The specific embodiment
Below will be by being elucidated in more detail with reference to the drawing embodiments of the invention.
(first embodiment)
As shown in Figure 1, toilet seat apparatus 5 is to constitute by the substrate 7 that the piezoelectric transducer that is wire 9 that will constitute voltage sensitive sensor is arranged at housing 8 according to an embodiment of the invention, and described housing 8 comprises by resin molded loam cake that forms 6 and substrate 7.
Here, as shown in Figure 2, the piezoelectric transducer that is wire 9 that uses is in the present embodiment described simply, pick off 14 is a kind of cable type pick offs that use piezoelectricity composition material, and by the heart yearn 18 (central electrode) that is arranged on the center in the axial direction, cover the piezoelectricity composition material 19 around the heart yearn 18, be arranged on piezoelectricity composition material 19 outer electrode 20 on every side, and PVC21 (Corvic) formation that is used to cover outermost.
Not have the piezoelectricity function with the piezoelectricity composition material 19 molded set piezoelectric transducers that are wire 9 of mode, therefore need to carry out certain and handle, be applied to piezoelectricity composition material 19 and provide piezoelectricity function (polarization is handled) for piezoelectricity composition material 19 by high direct voltage with several KV/mm.Piezoelectricity composition material 19 is carried out described polarization handle by after forming heart yearn 18 and outer electrode 20, between two electrodes 18,20, using DC voltage.
As shown in Figure 3, substrate 7 is equipped with 4 and is used to absorb ballistic pad 23, this pad 23 is attached to the rear surface of base plate 15, and when the device that is similar to background technology uses this toilet seat by being arranged between toilet seat apparatus 5 and the toilet main body 22, having a ballistic elastic force between absorptive substrate of being used for 7 and the toilet main body 22.In addition, toilet seat apparatus 5 is equipped with cap member 25, and cap member can be promoted to a side of water tank 24 with toilet seat apparatus 5.
According to present embodiment, the piezoelectric transducer 9 that is wire is fixedly arranged at substrate 7 by a plurality of keepers 26 that are provided with that are separated from each other.As shown in Figure 4, pad 23 is provided with the ledge 290 that passes the through hole 280 that is formed on the substrate 7, thus can and keeper 26 between piezoelectric transducer 9 contact to be configured for making the pressurizing unit of wire piezoelectric transducer 9 distortion.In addition, the inner surface of the loam cake 12 aforesaid heater 12 that has been fixed.
As shown in Figure 5, have in the toilet seat apparatus 5 of above-mentioned structure in use, when toilet seat apparatus 5 is set on the toilet main body 22 and applies when sitting the weight of human body M thereon, at the pressure that comes from toilet main body 22 by reception and in the compression gasket 23, ledge 290 projects upwards and such piezoelectric transducer 9 that pushes shown in double dotted line Fig. 4 from through hole 280.As a result, compare with the background technology that extrusion element is not provided, piezoelectric transducer 14 is applied in the vibration of with good grounds human motion via pad 23, and stably exports the signal of telecommunication.
Be supplied to control unit 13 according to the set signal of telecommunication of acceleration of vibration.
But, according to described toilet seat apparatus 5, shelter from the controlled unit 13 of the signal of telecommunication of piezoelectric transducer 9 output, thus make in the process of using toilet seat apparatus 5 by the vibration that drives generations such as washer jet, running hair-dryer or bath not can to the existence of human body whether, heart rate etc. constitutes noise.
In this way, piezoelectric transducer 9 produces the signal of telecommunication by extruding pad 23, and therefore described piezoelectric transducer 9 can produce the signal that is used to detect toilet seat apparatus distortion itself greater than background technology.
As shown in Figure 6, control unit 13 is provided with unshowned filter circuit, amplifying device, smoothing apparatus, determines device etc. in control section 29, and the heart rate accountant 30 that is used for calculating based on the output signal of smoothing apparatus heart rate is installed, be used to show the display device 31 of heart rate accountant 30 output signals, be used for the comparison means 32 that calculating is exported and setting value compares with heart rate accountant 30, and the warning generating means 33 that is used to give the alarm of result based on the comparison, the detection signal of piezoelectric transducer 9 outputs to control unit 13.
When piezoelectric transducer 9 detects the body kinematics of human body M and exports a signal of telecommunication, described control unit 13 filters the described signal of telecommunication by filter circuit, after this, by amplifying device the described signal of telecommunication is amplified and the described signal of telecommunication is carried out smoothly by smoothing apparatus.
As shown in Figure 7, when an object is installed on the toilet seat apparatus or described health when moving, that is landed in toilet seat apparatus 5 at human body M constantly, big output waveform is exported from smoothing apparatus.On the other hand, when human body M takes a seat thereon, thereupon enter a resting state, the little body kinematics of the human body that reason cardiac motion and Repiration are propagated has low level relatively output waveform by smoothing apparatus output.In contrast be that when human body M does not exist, or when an object is mounted thereto, after output one big output waveform, the waveform by smoothing apparatus output did not occur after the constant time period.
Therefore, described definite device compares output V and predetermined two setting numerical value Va, the Vb of smoothing apparatus to determine.That is, when V＜Va, confirmable is that a human body M or an object do not exist (non-existence output H :).When Va≤V＜Vb, confirmable to be human body exist (exist output H :) with resting state.In addition, when Vb＜V, confirmable is that human body M produces body kinematics (body kinematics output H :).When an object is installed in human body M present position, what can determine is that human body is taken a seat thereon or human body has been moved temporarily, be under the situation that object is disposed thereon, because the low level of propagating because of heart beating effect or Repiration vibration does not occur, determine that therefore human body M does not exist in human body M.
When definite device determined that a people takes a seat, deodorization apparatus and heater brought into operation.Described operating in determined just to stop when the people does not exist.In addition, the temperature control of heater monitoring heater 12.
In addition, the small-signal of propagating because of cardiac motion when human body M takes a seat with resting state is exported from smoothing apparatus.Based on described signal, thereby heart rate accountant 30 calculates the output heart rate.Result calculated shows by the display device 31 as external monitor.As shown in Figure 6, control unit 13 is equipped with the output signal that is used for comparison heart rate accountant 30 and the comparison means 32 of previous determined setting numerical value, and can give the alarm when heart rate be equal to or greater than setting value.Especially, heart rate increases when the people firmly drains, and can have the worry of bringing cerebral hemorrhage, but control unit 13 can be beneficial to healthy control by the generation of predicting this disease.In this case, when control unit 13 when being connected such as the network in hospital etc., not only use toilet seat apparatus in hospital to be concentrated and monitor, and the behavior in the lobby that can't directly be diagnosed always can be monitored.
In addition, the signal that arrives display device 31 can be transmitted by cable installation or wireless device via communicator.
According to above-mentioned toilet seat apparatus 5, by stably providing the signal of telecommunication, even piezoelectric transducer 9 obtains high reliability because of the light exercise that is easy to detect human body according to acceleration of vibration to control unit 13.In addition, piezoelectric transducer 9 has certain flexible, even and when impacting continuous action it also is difficult to when going up destroyedly, in addition, the described signal of telecommunication that is easy to distinguish people and object is output, and it is hereby ensured detection or similarly detection to taking a seat.
In addition, according to described toilet seat apparatus 5, ledge 290 is configured to by outstanding from the base plate 5 of substrate 7 and can contact with piezoelectric transducer 9, even so piezoelectric transducer 9 bases can stably export the signal of telecommunication in response to the very little acceleration of vibration that comes from human body.
In addition, by changing the shape of background technology product slightly, be used to absorb ballistic pad 23 and can be used as the pressurizing unit use yet, described pad can not invested on a large scale and produced.
In addition, although according to the foregoing description, whether exist, hearts rate etc. can be determined by the output signal that comes from piezoelectric transducer 9 is carried out smoothing processing, but may constitute a kind of structure, the output signal that wherein comes from piezoelectric transducer 9 is exaggerated as required, after this, be converted into numerical data by microcomputer etc. by the AD conversion, whether exist to be based on by the formed numerical value of numerical data rolling average is determined, perhaps heart rate etc. can be calculated by the automatic correction factor that calculates described numerical data.

By forming by this way, described elastomer 720 constitutes pressurizing unit, be used for being easy to crooked piezoelectric transducer 9 by contacting with human body, therefore described piezoelectric transducer 9 critically detects very little human motion, and can further stably export the signal of telecommunication.
In addition, when described elastomeric element 720 forms with the color that is different from loam cake 6, also can improve aesthetic feeling from design point of view.
The invention is not restricted to each above-mentioned embodiment, but can suitably be revised or improve.In addition, as long as the present invention can realize that material, shape, pattern that each building block is set are arbitrarily, and are hard-core in the various embodiments described above.
For example, although constituted the structure that piezoelectric transducer is installed on the side that heater surfaces is installed that is different from substrate, but because the piezoelectric transducer that is used among each embodiment is provided with aforesaid thermal resistance, therefore described piezoelectric transducer also can be set on the surface identical with described heater.
(the 4th embodiment)
According to described embodiment, especially the example that uses pressurizing unit to be made explanations, described pressurizing unit has elasticity, and wherein it is different from amplifying device with respect to the shape on the surface of vibration detecting sensor.
Fig. 1 is the decomposition diagram that illustrates according to the toilet seat apparatus of fourth embodiment of the invention, Fig. 2 is the perspective view that is used in the outward appearance of the vibrating sensor in the toilet seat apparatus among Fig. 1, Fig. 3 is to use the overall perspective view of the toilet of the toilet seat apparatus shown in Fig. 1, Figure 11 illustrates the cutaway view of the toilet seat apparatus of Fig. 1, Fig. 5 is the side view of the user mode of toilet shown in Figure 3, Fig. 6 is the structured flowchart of control unit in the toilet seat apparatus, and Fig. 7 is the sequential chart that pick off is exported and operated in toilet seat apparatus.
As shown in Figure 1, the toilet seat apparatus 5 of embodiment according to the present invention is to have certain flexible piezoelectric transducer 9 and constitute as substrate 7 places that vibration detecting sensor is arranged on housing 8 by being wire, and described housing 8 comprises that the loam cake 6 of rigid body is by the resin molded substrate that forms 7.
Herein, as shown in Figure 2, the simple piezoelectric transducer that is wire 9 that uses in the present embodiment of describing, pick off 9 is a kind of cable-shaped pick offs that are that use piezoelectricity composition material, and by the heart yearn that on axis direction, is arranged on the center (central electrode) 18, cover the piezoelectricity composition material 19 around the heart yearn 18, be arranged on the outer electrode 20 around the piezoelectricity composition material 19 and 21 formations of PVC (polyvinyl chloride resin) that are used to cover outermost.
In addition, compare with polymer piezoelectricity composition material, piezoelectric transducer 9 is provided with than hypersensitivity, and (10Hz or lower) obtains extra high susceptiveness in the low frequency region for the human body heart rate.This be because since the dielectric constant (about 55) of piezoelectricity composition material 19 greater than the dielectric constant (about 10) of polymer piezoelectricity composition material, even so sensitivity in low frequency region, also reduce very little.
Not have the piezoelectricity function with the piezoelectricity composition material 19 molded set piezoelectric transducers that are wire 9 of mode, therefore need to carry out certain and handle, be applied to piezoelectricity composition material 19 by high direct voltage and provide the piezoelectricity function for piezoelectricity composition material 19 with several KV/mm.Described polarization processing to piezoelectricity composition material 19 is carried out by apply DC voltage between two electrodes 18,20 after forming heart yearn 18 and lateral electrode 20.
As shown in Figure 3, substrate 7 is equipped with 4 and is used to absorb ballistic pad 23, this pad is attached to the rear surface of base plate 15, and when being similar to background technology and using this toilet seat, has the ballistic elastic force that is used for absorbing with toilet main body 22 between toilet seat apparatus 5 and the toilet main body 22 by being arranged on.In addition, toilet seat apparatus 5 is equipped with cap member 25, and cap member can be put forward a side to water tank 24 with toilet seat apparatus 5.
According to present embodiment, the piezoelectric transducer 9 that is wire is by being fixedly mounted on the substrate 7 by a plurality of keeper 26 location and supports that are provided with that are separated from each other.
On the amplification pad 23 as shown in Figure 11, constitute a kind of structure, this structure comprises the rubber-like pressurizing unit (amplifying device) 27 that is installed to as the inner surface of the loam cake 6 of rigid body, and the projection 28 (amplifying device) that is installed in the rigid body on the substrate 7, and clamp piezoelectric transducer 9 by pressurizing unit 27 and projection 28.Figure 11 (a) is illustrated in the state of integrating before loam cake 6 and the substrate 7, and Figure 11 (b) illustrates the state when loam cake 6 and substrate 7 screws are combined.When user is sitting on the toilet seat apparatus 5, the state shown in Figure 11 (b) can appear naturally, and loam cake 6 and substrate 7 are made of rigid body, even make that toilet seat apparatus 5 can be not destroyed when body wt is applied in thereon.
Here, described rigid body is defined by a kind of like this parts, just, even these parts also can not be out of shape and surpass its intensity when people's body wt applies thereon at least, especially, described rigid body allows the people not feel distortion, makes hip drop when the people sits thereon, and promptly user can not feel uneasy for intensity.The material that is used for it is not restricted especially, and can be a kind of resin-insulated material or pottery etc., perhaps can be metallic conductor etc., but what can increase is that the toilet seat of background technology normally is formed from a resin.
Now, although under user is sitting in situation on the toilet seat, all body wts of user are applied on the toilet seat, because loam cake 6 is made of rigid body, so loam cake is difficult to partly be out of shape.But what can expect is that toilet seat integral body is vibrated by the body kinematics of user, although this vibration is slight.How lower surface will be exaggerated the vibration of toilet seat and be transferred to piezoelectric transducer 9 provides detailed explanation.
At first, pressurizing unit 27 is set between loam cake 6 and the piezoelectric transducer 9, so pressurizing unit 27 is by vibration loam cake 6 and being vibrated, and still, the feature of described vibration is quite complicated.Because loam cake 6 is made of rigid body, pressurizing unit 27 is rubber-like parts, therefore, although near pressurizing unit 27 (be connected to loam cake 6 that part of) is similar to loam cake 6 vibrations, near the bottom of pressurizing unit 27 (be connected to piezoelectric transducer 9 that part of) vibration a little tardily, and be different from loam cake 6 and repetitive vibrations.Therefore, piezoelectric transducer 9 not only is transmitted as the vibration of the loam cake 6 of rigid body and substrate 7 but also is transmitted the different vibration that pressurizing unit 27 brings, and pressurizing unit 27 is carried out the vibration of so-called loam cake 6 and amplified.Therefore, pressurizing unit 27 can be considered to a kind of amplifying device.
Then, pressurizing unit 27 and piezoelectric transducer 9 are with configurations differing from one toward each other.Constitute such structure, wherein, piezoelectric transducer 9 is longer on the left and right directions of Figure 11, and pressurizing unit 27 is longer on the depth direction of Figure 11, in addition, although piezoelectric transducer 9 because of cable-shaped with flexure plane with respect to pressurizing unit 27, pressurizing unit 27 is with respect to a plane.Thus, piezoelectric transducer 9 has part that does not contact with pressurizing unit 27 and the part that contacts with pressurizing unit 27, and with part that pressurizing unit 27 contacts in, to the inapparent part of extruding, exist each several part from the part of brute force extruding with different squeezed states.Therefore, piezoelectric transducer 9 receives the different vibration of each several part, make the part place that contacts with pressurizing unit 27 not, the piezoelectric transducer 9 main vibrations that receive as rigid body, and being squeezed in the part place of pressurizing unit 27 in brute force, piezoelectric transducer 9 receives the vibration that is different from described rigid body that is produced by pressurizing unit 27.Piezoelectric transducer integral body does not receive identical vibration, but receives because of the different vibration of each several part, and this vibration is equal to the part distortion of piezoelectric transducer 9, therefore can increase the output of piezoelectric transducer.As a result, piezoelectric transducer 9 is deformed because of the vibration that comes from the rigid body that is difficult to be out of shape, and therefore, the vibration of described rigid body is exaggerated.Thus, the difference between the shape on the surface of pressurizing unit 27 respect to one another and piezoelectric transducer 9 can be considered for a kind of amplifying device.
Then, projection 28 and piezoelectric transducer 9 are faced mutually with configurations differing from one.Thus, piezoelectric transducer 9 is provided with part that does not contact with projection 28 and the part that contacts with projection 28.Therefore, relatively, receive vibration or do not receive vibration according to its described each several part piezoelectric transducer 9, make the part that contacts with projection 28 not, as the vibration of rigid body not by too much reception, and in the part that contacts with described projection 28, piezoelectric transducer 9 receives by the vibration of the projection 28 that is similar to substrate 7 or loam cake (rigid body) 6 as rigid body.But the integral body of piezoelectric transducer does not receive the integral body of identical vibration piezoelectric transducer and receives vibration or do not receive vibration according to each several part, and this vibration equals piezoelectric transducer 9 partly is out of shape, and the output of piezoelectric transducer can be increased.As a result, be slight although come from the distortion that vibration caused of the rigid body that is difficult to be out of shape, piezoelectric transducer 9 can be deformed, and therefore the vibration of described rigid body is exaggerated.Thus, the difference between the shape on the surface of projection 28 respect to one another and piezoelectric transducer 9 can be considered for a kind of amplifying device.But as mentioned above, the amplification effect that projection 28 is caused is less than the amplification effect of pressurizing unit 27.
Then, pressurizing unit 27 and projection 28 are faced mutually with configurations differing from one, and particularly, the area of pressurizing unit 27 is bigger.Because projection 28 is made of rigid body, only has the core of pressurizing unit 27 to be compressed, and at the core that compresses, the elasticity of pressurizing unit 27 is hindered, and is performed in the central part office near the vibration of rigid body.In addition, a power is applied in piezoelectric transducer 9 by pressurizing unit 27 and projection 28, and piezoelectric transducer 9 is fixed to a certain extent.The size of power also can be by pressurizing unit 27 elasticity and when loam cake 6 and substrate 7 combine the distance between them be changed.When the elasticity of pressurizing unit 27 is low or the distance between loam cake 6 and substrate 7 in short-term, piezoelectric transducer 9 is further applied described power and is firmly fixed.On the other hand, because described elasticity is maintained, the side (part not relative with projection 28) around the pressurizing unit 27 can be different from rigid body and be vibrated.Therefore, carry out the vibration approach rigid body thereby the core of pressurizing unit 27 is fixed, and pressurizing unit 27 around a side (not relative part) with projection 28 carried out the vibration that is different from rigid body by only pushing by pressurizing unit 27.In this case, it should be noted that the part of carrying out the vibration approach rigid body and the part that is different from the vibration of described rigid body are set at position very close each other in the piezoelectric transducer 9.Receive different each other vibrations in very close each other position, this equates piezoelectric transducer 9 and be out of shape partly, so the output of piezoelectric transducer can be increased.As a result, be slight although come from the distortion that vibration caused of the rigid body that is difficult to be out of shape, piezoelectric transducer 9 can be deformed, and therefore the vibration of described rigid body is exaggerated.Therefore, the difference between the shape on the surface of pressurizing unit 27 and projection 28 can be considered for a kind of amplifying device.Here, projection 28 may not be a rigid body.Even because when projection 28 is made of elastomer, elasticity can or shorten distance between loam cake 6 and the substrate 7 and push described pressurizing unit 27 forcefully and hindered at core by the height by increasing pressurizing unit 27 or projection 28.
Here, for the elasticity of pressurizing unit 27, described elasticity can be higher than the elasticity of loam cake, and obtains the above-mentioned effect as amplifying device.For example, can use representational padded coaming thus, and described pressurizing unit 27 can be made of rubber or sponge.
As shown in Figure 5, have in the toilet seat apparatus 5 of above-mentioned structure in use, when toilet seat apparatus 5 is arranged on the toilet main body 22 and is applied in when sitting the weight of human body M thereon, just as described above, piezoelectric transducer 9 is extruded.As a result, the vibration of moving corresponding to human body M is exaggerated, thereby is applied on the piezoelectric transducer 9, stably to export the signal of telecommunication.
The signal of telecommunication that provides according to acceleration of vibration is supplied to control unit 13.
But, sheltered by control unit 13 from the signal of telecommunication of piezoelectric transducer 9 outputs, thereby in using toilet seat apparatus 5, by the vibration that drives generations such as cleaning nozzle, operation blower fan or bath can not be configured for whether human body exists, the noise of heart rate etc.
As shown in Figure 6, control unit 13 is provided with unshowned filter circuit in the inboard of control section 29, amplifying device, smoothing apparatus, determine device etc., and be equipped with and be used for calculating the heart rate accountant 30 of heart rate based on the output signal of smoothing apparatus, be used to show the display device 31 of the output signal of exporting accountant 30, be used for the comparison means 32 that compares with setting value is exported in the calculating of heart rate accountant 30, and being used for the alarm issue device 33 that result based on the comparison gives the alarm, the detection signal of piezoelectric transducer 9 is imported into described control unit 13.
The health that detects human body M when piezoelectric transducer 9 moves and when exporting the signal of telecommunication, control unit 13 filters the described signal of telecommunication by filter circuit, subsequently, amplifies the described signal of telecommunication by amplifying device, in addition, by smoothing apparatus the described signal of telecommunication is carried out smoothly.
As shown in Figure 7, human body M be sitting on the toilet seat apparatus 5 that constantly, when object is mounted thereto, or when human body moved, big output waveform was output from smoothing apparatus.On the other hand, sit thereon at human body M, when resting state occurring, the little body kinematics of the human body that produces because of cardiac motion or Repiration, low level relatively waveform output is output from smoothing apparatus.
On the other sidely be, when human body M does not occur or when object is mounted thereto, after exporting big output waveform, is not illustrated with constant interval by the smoothing apparatus output waveform.
Therefore, determine that device compares output V and predetermined two setting values Va, the Vb of smoothing apparatus according to following, thereby determine.That is, when V＜Va, confirmable is that human body M or object do not exist (do not exist output H :).When Va≤V＜Vb, confirmable to be human body exist (exist output H :) with resting state.In addition, when Vb＜V, confirmable is that human body M produces body kinematics (body kinematics output H :).When object is installed in human body M present position, although to take a seat or health moves determines to carry out temporarily, but, the low utmost point of propagating because of heart beating effect or Repiration when human body M does not exist can not occur because vibrating, so by the state of placing object determined that confirmable is that human body M does not exist.
When definite device was determined taking a seat of people, odor removal and heater began starting.When determining the people and do not exist, described operation stops.
In addition, described heater is handled the temperature control of heater 12.
In addition, the small-signal of being propagated by the heart beating action when human body M sits thereon with resting state is exported from described smoothing apparatus.Based on described signal, thereby calculate described heart rate output by heart rate accountant 30.Result of calculation is shown by the display device 31 as external monitor.In addition, as shown in Figure 6, control unit 13 is equipped with and is used for the comparison means 32 that output signal and predefined numerical value with heart rate accountant 30 compare, and being used for the alarm issue device 33 that the output by comparison means 32 gives the alarm, this device can give the alarm when heart rate is equal to or greater than setting value.Especially, when the people exerted oneself when draining, heart rate increased and can exist the worry of cerebral hemorrhage occurring, and still, control unit 13 is beneficial to healthy control by predicting this accident.In this case, when control unit 13 is connected to such as hospital etc. by network, not only use toilet seat apparatus 5 in hospital to be concentrated and monitor, and the behavior in the lobby that can't directly be diagnosed always can be monitored.
In addition, the signal of arrival display device 31 can be transmitted with non-wireless means or wireless device via communicator.
According to above-mentioned toilet seat apparatus 5, piezoelectric transducer 9 obtains high reliability by stably being easy to detect very slight human motion to control unit 13 supply according to the signal of telecommunication of acceleration of vibration.In addition, because piezoelectric transducer 9 is flexible, even and also be difficult to the detection signal that destroyed and output helps distinguishing people and object thereon the time impacting continuous action, described piezoelectric transducer 9 can stably detect takes a seat etc.
In addition, although according to the above embodiments, by the output signal that smoothly comes from piezoelectric transducer 9 can determine whether to exist, heart rate etc., but can construct a kind of like this structure, wherein the output signal of piezoelectric transducer 9 is exaggerated on demand, and be converted into numerical data by microcomputer etc. by the AD conversion subsequently, whether exist to be based on by described numerical data is carried out rolling average in described microcomputer definitely, perhaps heart rate size etc. is to calculate by the automatic correction factor that calculates numerical data.
Will summarize to the effect of the foregoing description.
Constituted a kind of structure, it comprises: be used for amplifying pressurizing unit (amplifying device) 27, the projection (amplifying device) 28 of the vibration be delivered to loam cake 6 (rigid body) and comprise the piezoelectric transducer (vibration detecting sensor) 9 that is used to detect the vibration that is exaggerated and by pressurizing unit (amplifying device) 27, projection (amplifying device) 28 and piezoelectric transducer (vibration detecting sensor) 9 formed vibration detection devices 34.
Thus, although loam cake (rigid body) 6 is difficult to be out of shape by the vibration that is sent to loam cake (rigid body) 6, the vibration that is sent to loam cake (rigid body) 6 is amplified by amplifying device and is detected by vibration detecting sensor 34, and the vibration that therefore is sent to loam cake (rigid body) 6 can accurately be detected.
In addition, as amplifying device, can construct a kind of structure, this structure comprises pressurizing unit 27, and described device has the elasticity that is used to push piezoelectric transducer 9 (vibration detecting sensor).
Therefore, pressurizing unit 27 is vibrated by the vibration of loam cake 6 (rigid body), because pressurizing unit 27 is provided with elasticity, piezoelectric transducer (vibration detecting sensor) 9 can be pushed by the vibration that is exaggerated greater than the vibration of loam cake (rigid body) 6.
In addition, as amplifying device, constitute a kind of like this structure, this structure comprises pressurizing unit 27, and this pressurizing unit 27 pushes piezoelectric transducer 9 (vibration detecting sensor) by the shape that makes its surface with respect to piezoelectric transducer have the surface that is different from piezoelectric transducer.
Therefore, because the shape on the surface of piezoelectric transducer respect to one another (vibration detecting sensor) 9 and pressurizing unit 27 differs from one another, locate at piezoelectric transducer 9 (vibration detecting sensor), can occur vibrating by the parts of pressurizing unit 27 powerful extruding and the part of too not pushed because of loam cake 6 (rigid body), and compare in the situation that all surface is evenly pushed with piezoelectric transducer (vibration detecting sensor) 9, the vibration that described piezoelectric transducer (vibration detecting sensor) 9 can be exaggerated is pushed.
In addition, vibration detecting sensor is constituted by having flexible piezoelectric transducer 9.
Therefore, when piezoelectric transducer 9 received vibration, piezoelectric transducer 9 was easily deformable, produced the output corresponding to described distortion, therefore can accurately be exported corresponding to the output of described vibration.
In addition, according to the toilet seat apparatus 5 with vibration detection device 34, constructed a kind of like this structure, wherein rigid body is loam cake 6 (rigid body), substrate 7, and the body kinematics that is sent to the user of toilet is detected.
Therefore, even when toilet seat is difficult to body kinematics by the user that is sent to toilet seat when being out of shape, the body kinematics that is sent to the user of toilet seat is amplified by amplifying device, and by 9 detections of piezoelectric transducer (vibration detection device), the body kinematics that therefore is sent to the user of toilet seat can accurately be detected.
In addition,, constructed a kind of like this structure according to toilet seat apparatus 5, this structure be used for detecting come from the taking a seat of user body kinematics, heart beating, breathing at least one of them.
Therefore, it is easy taking a seat for detection, promptly user is sat movable information thereon or is easy based on the heart rate of the user of accurate detection body kinematics or the bio information of breathing, and can realize can full use detecting the multifunctional closestool seat device 5 of information.
In addition, with shown in Figure 11 comparing, will have certain elasticity and have special use and make an explanation with respect to the pressurizing unit on the difform surface of vibration detecting sensor other example as amplifying device.
At first, Figure 12 (a) illustrates the example with different structure to 12 (c).Figure 12 (a) is illustrated in the structure that each position is provided with pressurizing unit (amplifying device) 27 and projection (amplifying device) 28.Figure 12 (b) illustrates to use to have certain elastic pressurizing unit 35 and replaces the structure of the projection of rigid body as amplifying device, and wherein the right end position of pressurizing unit 27 and pressurizing unit 35 is aligned and therefore their left position staggers each other.In Figure 12 (c), piezoelectric transducer 9 (vibration detecting sensor) is set on the side with respect to pressurizing unit 36 of loam cake (rigid body) 6, and is directly fixed on described loam cake (rigid body) 6 especially.
Figure 13 (a) illustrates such example to 13 (c), and wherein, the shape on the surface of pressurizing unit respect to one another (amplifying device) and piezoelectric transducer (vibration detecting sensor) differs from one another.In Figure 13 (a), recess 38 is formed on pressurizing unit (amplifying device) 37 places.Naturally, a jut can be set.In Figure 13 (b), a plurality of pressurizing units (amplifying device) 39 are set.In Figure 13 (c), with respect to piezoelectric transducer 9, and described piezoelectric transducer (vibration detecting sensor) the 9th is crooked with the plane for pressurizing unit 40.
Figure 14 (a) and 14 (b) illustrate other example of rubber-like pressurizing unit (amplifying device).In Figure 14 (a), a spring is as pressurizing unit 41 (amplifying device).The pressurizing unit 42 (amplifying device) of Figure 14 (b) has elasticity by thin flexible member crooked and that fixedly be made of metal.
(embodiment 5)
According to present embodiment, will special use not had elasticity and have with respect to the pressurizing unit on the difform surface of the vibration detecting sensor example as amplifying device to make an explanation.
Figure 15 (a) is the structure chart that illustrates according to the part of the bathtub device of fifth embodiment of the invention, and Figure 16 is the profile of the major part of Figure 15 (a).
Shown in Figure 15 (a), according to the bathtub device of the embodiment of the invention at the bathtub 43 of rigid body and cover be provided with between 44 have certain flexible be wire, as the piezoelectric transducer 45 of vibration detecting sensor.In addition, described bathtub device comprises the projection 46 of giving prominence to piezoelectric transducer 45 from bathtub 43, is used for supporting at lid 44 places the keeper 47 of piezoelectric transducer 45, and described piezoelectric transducer 45 is positioned by the hole 48 of keeper 47.
Here, projection 46 and piezoelectric transducer 45 toward each other, their shape differs from one another.Constitute a kind of like this structure, wherein piezoelectric transducer 9 is longer on the left and right directions of Figure 16, and described projection 46 is longer on the depth direction of Figure 16, in view of piezoelectric transducer 9 has a flexure plane because of cable-shaped, and it is relative on left and right directions with constant shape, described projection 46 is configured to such shape, and its core is further outstanding on left and right directions.Therefore, described piezoelectric transducer 45 has part that does not contact with projection 46 and the part that contacts with described projection 46, in addition, in the part that contacts with described projection 46, to the part that is not subjected to too big extruding various parts with different pressured states can appear from the part (center) of powerful pressurized.
Except described here, although being connected to via keeper 47, piezoelectric transducer 45 covers 44, and whether state is rigid body or elastomer by described lid 44, and in addition, keeper 47 is rigid body or elastomer and change to some extent.
At first, when lid 44 when not having one to be fixed on the bathtub 43, regardless of covering 44 the material or the material of keeper 47,, cover 44 and do not vibrated although bathtub 43 is vibrated by the body kinematics of user.The vibration of bathtub 43 only is sent to piezoelectric transducer 45 from projection 46, so piezoelectric transducer 45 only receives the vibration that comes from itself and projection 46 contacted parts, and it does not receive vibration with projection 46 contacted parts.The integral body of piezoelectric transducer 45 does not receive identical vibration, but piezoelectric transducer 45 has received the different vibration of each several part, and described vibration equals the part distortion of piezoelectric transducer 45, so the output of piezoelectric transducer 45 can be enhanced.As a result, described piezoelectric transducer 45 can be deformed by the vibration of the bathtub 43 (rigid body) that is difficult to be out of shape, so the vibration of bathtub (rigid body) 43 has been exaggerated.Therefore, can be construed to be a kind of amplifying device to the difference between the shape of the face of projection 46 respect to one another and piezoelectric transducer 45.
Then, when lid 44 is fixed in bathtub 43 integratedly and covers 44 and keeper 47 when one of them is made of elastomer at least, bathtub 43 is vibrated because of the body kinematics of user, and the vibration of being undertaken by lid 44 and keeper 47 is made of the vibration that is different from bathtub 43 because of the flexible member vibration.Although the vibration of bathtub 43 is sent to piezoelectric transducer 45 from projection 46, cover in addition 44 and the vibration carried out of keeper 47 be sent to piezoelectric transducer 46, so piezoelectric transducer 45 receive because of with the part and the different vibration of part that contacts with keeper 47 of projection 46 contacts.The integral body of piezoelectric transducer 45 does not receive identical vibration, but piezoelectric transducer 45 has received the different vibration of each several part, and described vibration equals the part distortion of piezoelectric transducer 45, so the output of piezoelectric transducer 45 can be enhanced.As a result, described piezoelectric transducer 45 can be deformed by the vibration of the bathtub 43 (rigid body) that is difficult to be out of shape, so the vibration of bathtub (rigid body) 43 has been exaggerated.Therefore, projection 46, lid 44, keeper 47 can be construed to constitute a kind of amplifying device.
At last, lid 44 be fixed in described bathtub 43 integratedly and cover 44 and keeper 47 situation about constituting by rigid body under, when bathtub 43 is vibrated by the body kinematics of user, look the vibration that is sent to piezoelectric transducer 45 from projection 46 with constituted by identical vibration with the vibration that keeper 47 is carried out by lid 44.But from microcosmic, existing between them can't be by the JND that the people determined.That is, when bathtub 43 vibrations, projection 46 is vibrated at once, and still, keeper 47 can not vibrate immediately.After bathtub 43 vibrations, lid 47 is vibrated via being in bathtub 43 coupling part on every side, and further vibration of keeper 47 beginnings after this.That is, the path of transmission vibration is longer.Therefore, piezoelectric transducer 45 is by receiving different slightly vibrations with projection 46 contacted parts with keeper 47 contacted parts.The integral body of piezoelectric transducer 45 does not receive identical vibration, but piezoelectric transducer 45 has received the different vibration of each several part, and described vibration equals the part distortion of piezoelectric transducer 45, so the output of piezoelectric transducer 45 can be enhanced.As a result, described piezoelectric transducer 45 can be deformed by the vibration of the bathtub 43 (rigid body) that is difficult to be out of shape, so the vibration of bathtub (rigid body) 43 has been exaggerated.Therefore, projection 46, lid 44, keeper 47 can be construed to constitute a kind of amplifying device.But in this case, described enlarging function is less than the enlarging function under the above-mentioned situation, and therefore suggestion uses the circuit of processes sensor output to increase amplification coefficient etc.
Now, present embodiment comprises other structure with enlarging function.
At first, described piezoelectric transducer 45 is elastic.Described piezoelectric transducer 45 with flexible (flexural properties) also has elasticity, therefore described piezoelectric transducer 45 can be vibrated by the vibration of the projection 46 that keeps in touch with piezoelectric transducer 45 and the vibration that comes from keeper 47 in essence, especially, because of the elasticity of piezoelectric transducer 45, can produce this vibration that is different from original vibration.That is, this is a kind of like this mechanism, wherein when the output that produces with respect to the original vibration that is provided, vibrates other output and still can produce by producing the difference that is produced by piezoelectric transducer 45 in fact.
Below, piezoelectric transducer 45 is installed in and is applied in in certain tensile state.In Figure 16, piezoelectric transducer 45 is supported on and is applied in the described tensile state, promptly is in the state that is strained at.At this moment, vibration is propagated fartherly than not applying tensile situation in piezoelectric transducer 45.When piezoelectric transducer 45 is applied in a way tension force, come from the vibration of projection 46, the vibration that comes from the keeper 47 that contacts with piezoelectric transducer 45 is propagated fartherly in piezoelectric transducer 45, the result, in piezoelectric transducer 45, described output can produce from all places.According to this point, what can conceive is can obtain the effect identical with increasing the sensor sensing degree, i.e. amplification vibration.In addition, for preferably applying the how tension force of degree, preferably constitute a scope, wherein the mechanical strength of piezoelectric transducer 45 can not degenerated at least, particularly can keep elastic scope.In addition, Figure 17 (a) illustrates other example that uses pressurizing unit, and this device does not have elasticity, and wherein is different from amplifying device with respect to the shape on the surface of vibration detecting sensor.
In Figure 17 (a), projection (amplifying device) 49 is formed on to be covered on 44 the side, and keeper 47 is formed on the side of bathtub 43.In addition, Figure 17 (a) illustrates other example that uses pressurizing unit, and this device does not have elasticity, and wherein is different from amplifying device with respect to the shape on the surface of vibration detecting sensor.
In addition, although according to present embodiment, described bathtub is illustrated as rigid body, and historically, described bathtub is made by various materials.Described material is by timber, resin, stainless steel metal etc., marble, rock, tile etc.The rigid body that is used for bathtub can be suitable for, and is constituted as long as described rigid body is a material by the remarkable distortion that can not occur being felt by user in normal shower, vibrates to occur in the described material.
(embodiment 6)
According to present embodiment, will make an explanation to the example of special use pressurizing unit as amplifying device, be provided with elasticity in the described pressurizing unit, and wherein equate with respect to the shape on the surface of the pressurizing unit of vibration detecting sensor.
Figure 18 (a) is the structure chart that the shower of sixth embodiment of the invention is shown, and Figure 19 is the cutaway view of Figure 18 (a) major part.
According to the shower of the embodiment of the invention, shown in Figure 18 (a), described shower can use at the height of taking a seat, and people can be present and uses the hot water from a plurality of shower nozzles 51 ejections to wash under the state of seat 50.Internal integration at the seat 50 of rigid body has vibration detection device 52, and vibration detection device 52 comprises rubber-like piezoelectric transducer 53 in the form of sheets as vibration detecting sensor, and rubber-like pressurizing unit 54 is as amplifying device.As shown in Figure 19, even thereby the shape of working as the surfaces opposite to each other of pressurizing unit 54 and piezoelectric transducer 53 is flat being equal to each other, constitutes by center to have the structure of chamber 53 at pressurizing unit 54, and described amplification is exaggerated.Consider the situation that is used to push the crimping section 56 of piezoelectric transducer 53 and between the two, does not insert chamber 55, and be used to push the crimping section 57 of piezoelectric transducer 53 and between the two, insert the situation of chamber 55, the extruding of 56 pairs of piezoelectric transducers 53 of described crimping section is stronger, but a little less than the extruding of 57 pairs of piezoelectric transducers 53 of crimping section, this can be construed to is to have to be similar to (b) structure of function of Figure 13 (a).
That is, in piezoelectric transducer 53, have a part, this part receives by the brute force of crimping section 56 and pushes the brute force vibration that is produced, and also has a part, and this part does not receive the too many not many vibration that extruding produced by crimping section 57.The integral body of piezoelectric transducer 53 does not receive identical vibration, but piezoelectric transducer 53 has received the different vibration of each several part, and described vibration equals the part distortion of piezoelectric transducer 53, and therefore the output of piezoelectric transducer 53 can be enhanced.As a result, described piezoelectric transducer 53 can be deformed by the vibration of the rigid body (seat 50) that is difficult to be out of shape, so the vibration of rigid body has been exaggerated.As a result, pressurizing unit 54 can further amplify vibration by cavity 55, crimping section 56,57.
In addition, Figure 20 illustrates special use pressurizing unit other embodiment as amplifying device, and described pressurizing unit is provided with elasticity, and wherein equates with respect to the shape on the surface of the pressurizing unit of vibration detecting sensor.
In Figure 20, provide and have different elastic first pressurizing unit (amplifying device) 58 and second pressurizing units (amplifying device) 59, and different vibrations is sent on the surface of each pressurizing unit with respect to piezoelectric transducer 53 because of the difference between each elasticity as pressurizing unit.The integral body of piezoelectric transducer 53 does not receive identical vibration, but piezoelectric transducer 53 has received the different vibration of each several part, and described vibration equals the part distortion of piezoelectric transducer 53, and therefore the output of piezoelectric transducer 53 can be enhanced.Described piezoelectric transducer 53 can be deformed by the vibration of the rigid body (seat 50) that is difficult to be out of shape, and the vibration of rigid body has been exaggerated.As a result, the elastic difference between first pressurizing unit (amplifying device) 58 and second pressurizing unit (amplifying device) 59 can be taken as the amplifying device that is used to amplify described rigid body (seat 50) vibration.
In addition, the piezoelectric transducer of present embodiment 53 is with cable-shaped formation, and by piezoelectricity composition material being connected to piezoelectric patches 60 and will being connected to that two surfaces of piezoelectric patches 60 constitute with lamellar as the conductive rubber 61 of electrode.
In addition, although in Figure 12,13,14,17 (a), 19,20, between pressurizing unit and described projection and piezoelectric transducer, there is the gap, be similar to Figure 11 (a), to explain a gap be set in order to simplify, and described gap when being arranged in actual use two parts contact with each other.
(embodiment 7)
According to present embodiment, will be to making an explanation in the inner example of vibration detecting sensor being installed and constituting standing part in the outside of rigid body of rigid body (toilet seat).
Fig. 1 is the decomposition diagram that illustrates according to the toilet seat apparatus of seventh embodiment of the invention, Fig. 2 is the perspective view that is used in the outward appearance of the vibrating sensor in the toilet seat apparatus among Fig. 1, Fig. 3 is to use the overall perspective view of the toilet of the toilet seat apparatus shown in Fig. 1, Figure 11 illustrates the cutaway view of major part of the toilet seat apparatus of Fig. 1, Fig. 5 is the side view of the user mode of toilet shown in Figure 3, Fig. 6 is the structured flowchart of control unit in the toilet seat apparatus, and Fig. 7 is the sequential chart that pick off is exported and operated in toilet seat apparatus.
As shown in Figure 1, the toilet seat apparatus 5 of embodiment according to the present invention is to have certain flexible piezoelectric transducer 9 and constitute as the substrate 7 that vibration detecting sensor is arranged on housing 8 by being wire, and described housing 8 comprises by the loam cake 6 of the resin molded rigid body that forms and substrate 7.
Herein, simple description as shown in Figure 2 to the piezoelectric transducer that is wire 9 that uses in the present embodiment, pick off 9 is a kind of cable-shaped pick offs that are that use piezoelectricity composition material, and by the heart yearn (central electrode) 18 that on axis direction, is arranged on the center, cover the piezoelectricity composition material 19 around the heart yearn 18, be arranged on the outer electrode 20 around the piezoelectricity composition material 19 and 21 formations of PVC (polyvinyl chloride resin) that are used to cover outermost.
In addition, compare with polymer piezoelectricity composition material, piezoelectric transducer 9 is provided with hypersensitivity, and (10Hz or lower) obtains extra high susceptiveness in the low frequency region for the human body heart rate.This be because since the dielectric constant (about 55) of piezoelectricity composition material 19 greater than the dielectric constant (about 10) of polymer piezoelectricity composition material, also very little even sensitivity reduces in low frequency region.
Not have the piezoelectricity function with the piezoelectricity composition material 19 molded set piezoelectric transducers that are wire 9 of mode, therefore need to carry out certain and handle, be applied to piezoelectricity composition material 19 by high direct voltage and provide the piezoelectricity function for piezoelectricity composition material 19 with several kV/mm.Described polarization processing to piezoelectricity composition material 19 is carried out by apply DC voltage between two electrodes 18,20 after forming heart yearn 18 and lateral electrode 20.
As shown in Figure 3, substrate 7 is equipped with 4 and is used to absorb ballistic pad 23, this pad 23 is attached to the rear surface of base plate 15, and has when using the toilet seat be similar to background art device the elastic force that is used between toilet seat apparatus 5 and the toilet main body 22 absorbing with the collision of toilet main body 22 by being arranged on.Although described pad 23 is shanks of toilet seat apparatus 5, described pad 23 still is a kind of toilet seat apparatus 5 standing parts that are used for fixing toilet main body 22, when user is sat thereon, the weight of health applies thereon, and pad 23 is by being fixed to be extruded to than the state on the hard toilet main body 22 of toilet seat.Therefore, when toilet seat was vibrated because of the health vibration that receives user, near the of pad 23 was maintained under the state that is difficult to be vibrated because of being fixed in toilet main body 22.
In addition, toilet seat apparatus 5 is equipped with cap member 25, and cap member can be promoted to a side of water tank 24 with toilet seat apparatus 5.
According to present embodiment, the piezoelectric transducer 9 that is wire is by being installed on the substrate 7 by a plurality of keeper 26 location and supports that are provided with that are separated from each other.
As shown in Figure 11, when one of them periphery of four pads 23 amplifies, a kind of structure is arranged, this structure comprises having inner surface and the rubber-like pressurizing unit 27 that is connected to loam cake 6 (rigid body), and the projection 28 that is connected the rigid body on the substrate 7 (rigid body), be used for clipping piezoelectric transducer 9 by pressurizing unit 27 and projection 28.Figure 11 (a) is illustrated in the state of integrating before loam cake 6 and the substrate 7, and Figure 11 (b) illustrates and loam cake 6 and substrate 7 is threaded and state when combining.When user is sitting on the toilet seat apparatus 5, the state shown in Figure 11 (b) can appear naturally, and loam cake 6 and substrate 7 are made of rigid body, even make that toilet seat apparatus 5 can be not destroyed when body wt is applied in thereon yet.
Here, described rigid body is defined as a kind of like this parts, even these parts can not be out of shape and surpass its intensity when people's body wt applies thereon at least, especially, described rigid body is defined as a kind of like this parts, and these parts make hip drop when the people sits thereon, people not feel distortion, promptly be a kind of like this parts, user can not feel concern for described intensity.But material is not restricted especially, and can be insulant such as a kind of resin, pottery, perhaps can be metallic conductor etc., and what can increase is that the toilet seat of background technology normally is formed from a resin.
Now, in accompanying drawing 11 (b), when user is sat thereon, pad 23 constitutes because of being fixed in toilet main body 22 and is difficult to the standing part that vibrated, the substrate 7 and the projection 28 that are connected to pad 23 all are to be made of rigid body, so substrate 7 and projection 28 are difficult to be vibrated and can piezoelectric transducer 9 in the state lower support that is difficult to from piezoelectric transducer lower surface vibration piezoelectric transducer 9.But,,, be easy to vibration more more away from pad 23 because the shape of substrate 7 is big.On the other hand, look that vibration is easy to transmit, and loam cake 6 is vibrated according to body kinematics because loam cake (rigid body) 6 directly contacts user in loam cake 6 (rigid body), and constitute a kind of like this structure, be about to vibration via pressurizing unit 27 be sent to piezoelectric transducer 9 above.Therefore, under lower surface being remained in the state that is difficult to be vibrated in because piezoelectric transducer 9 receives the vibration that comes from top loam cake 6 (rigid body), piezoelectric transducer 9 can accurately detect vibration.Especially, the piezoelectric transducer 9 of use in described embodiment produces a signal according to the acceleration that is provided to piezoelectricity composition distortion of materials, therefore do not vibrate lower surface by only vibrating upper surface, effectively shrink and extend piezoelectricity composition distortion of materials acceleration and can be received and can produce big output signal.
Now, be sitting at user under the state of toilet seat, although the overall weight of user is applied on the toilet seat, because loam cake 6 is made of rigid body, loam cake 6 is difficult to partly be out of shape.But although look that vibration is little, the integral body of toilet seat is vibrated by the body kinematics of user.How vibration for toilet seat is exaggerated and is sent to piezoelectric transducer 9, below can provide detailed explanation to this.
At first, because pressurizing unit 27 is set between loam cake 6 and the piezoelectric transducer 9, pressurizing unit 27 is vibrated by vibration loam cake 6, the described vibration performance complexity very that becomes.Though loam cake 6 is made of rigid body, but pressurizing unit 27 is constituted by having certain elastic parts, therefore, though the top of pressurizing unit 27 (be connected to loam cake 6 that part near) be similar to loam cake 6 and vibrated, the bottom of pressurizing unit 27 (be connected to piezoelectric transducer 9 that part near) a little lingeringly vibrated, to repeat to be different from the vibration of loam cake 6.Therefore, piezoelectric transducer 9 not only is transmitted the vibration as the loam cake 6 of rigid body, and is transmitted the difference vibration that is produced by pressurizing unit 27, and the vibration of the so-called loam cake 6 of pressurizing unit 27 amplifications.Therefore, can be construed to be a kind of amplifying device to pressurizing unit 27.
Below, pressurizing unit 27 and piezoelectric transducer 9 are with configurations differing from one toward each other.In the structure that is constituted, piezoelectric transducer 9 is longer on the left and right directions of Figure 11, and pressurizing unit 27 is big on the depth direction of Figure 11, and constitute a kind of like this structure, though wherein piezoelectric transducer 9 because of cable-shaped bending with curved surface with respect to pressurizing unit 27, pressurizing unit 27 is with respect to a plane.Thus, piezoelectric transducer 9 has part that does not contact with pressurizing unit 27 and the part that contacts with pressurizing unit 27, and with part that pressurizing unit 27 contacts in, to the inapparent part of extruding, exist various parts from the part of brute force extruding with different squeezed states.Therefore, according to piezoelectric transducer 9, vibration is different because of each several part, this makes the part place that contacts with pressurizing unit 27 not, piezoelectric transducer 9 does not receive too many vibration, and at the part place by pressurizing unit 27 powerful extruding, piezoelectric transducer 9 receives strong vibration.Piezoelectric transducer integral body does not receive identical vibration but receives because of the different vibration of each several part, and this vibration is equal to the part distortion of piezoelectric transducer 9, so the output of piezoelectric transducer can increase.As a result, piezoelectric transducer 9 is deformed because of the vibration that comes from the rigid body that is difficult to be out of shape, and therefore the vibration of described rigid body is exaggerated.Therefore, the difference between the shape on the surface of pressurizing unit 27 respect to one another and piezoelectric transducer 9 can be considered for a kind of amplifying device.
Below, projection 28 and piezoelectric transducer 9 are with configurations differing from one toward each other.Therefore, piezoelectric transducer 9 is provided with part that does not contact with projection 28 and the part that contacts with projection 28.Therefore, piezoelectric transducer 9 with projection 28 contacted parts can be not too many being fixed and being easy to and receive vibration from pressurizing unit 27, and with projection 28 contacted parts, be fixed in pad 23 via substrate 7, and be difficult to receive the vibration that comes from pressurizing unit 27.That is, piezoelectric transducer 9 receives and does not receive to vibrate and depends on described each several part.The integral body of piezoelectric transducer does not receive identical vibration, but the integral body of piezoelectric transducer receives vibration or do not receive vibration according to each several part, and this vibration equals piezoelectric transducer 9 partly is out of shape, and the output of piezoelectric transducer can be increased.As a result, be slight although come from the vibration of the rigid body that is difficult to be out of shape, piezoelectric transducer 9 can be deformed, and the vibration of described rigid body is exaggerated.Therefore, the difference between the shape of the face of projection 28 respect to one another and piezoelectric transducer 9 can be considered for a kind of amplifying device.But, look that amplification effect that projection 28 is caused is less than the amplification effect of above-mentioned pressurizing unit 27.
Below, pressurizing unit 27 and projection 28 with configurations differing from one toward each other, particularly, the area of pressurizing unit 27 is big.Because projection 28 is to be made of rigid body, only has the core of pressurizing unit 27 to be compressed, at the core of compression, the elasticity of pressurizing unit 27 is hindered, and the vibration that therefore approaches loam cake 6 vibrations is performed in the central part office.In addition, power is applied in piezoelectric transducer 9 by pressurizing unit 27 and projection 28, and piezoelectric transducer 9 is fixed to a certain extent.The size of power also can be by pressurizing unit 27 elasticity and when loam cake 6 and substrate 7 combine the distance between them be changed.When the elasticity of pressurizing unit 17 is low and the distance between loam cake 6 and substrate 7 in short-term, piezoelectric transducer 9 is further applied described power and is firmly fixed.On the other hand, on the side around the pressurizing unit 27 (not relative with projection 28 part), because described elasticity is maintained, the vibration that is different from loam cake 6 can be performed.Therefore, core at pressurizing unit 27, piezoelectric transducer 9 approaches the vibration of loam cake 6 vibrations, and the side around pressurizing unit 27 (that not relative part) with projection 28, piezoelectric transducer 9 vibrates, and this vibration only is different from the vibration of the loam cake 6 that causes by the extruding by pressurizing unit 27.In this case, it should be noted that the part of the vibration that approaches loam cake 6 vibration and the part that is different from the vibration of loam cake 6 vibrations are set at position very close each other in the piezoelectric transducer 9.Piezoelectric transducer 9 receives different each other vibrations in very close each other position, this equates piezoelectric transducer 9 and be out of shape partly, so the output of piezoelectric transducer can be increased.As a result, be slight although come from the vibration of the rigid body that is difficult to be out of shape, piezoelectric transducer 9 can be deformed, and therefore the vibration of described rigid body is exaggerated.Therefore, the difference between the shape of the face of pressurizing unit 27 respect to one another and projection 28 can be considered for a kind of amplifying device.
In this case, projection 28 can not be a rigid body.Therefore even when projection 28 is made of elastomer, by increasing the height of pressurizing unit 27 or projection 28, or the distance between shortening loam cake 6 and the substrate 7, by compressing pressurizing unit 27 forcefully in the central part office, described elasticity can be hindered.
Here, for the elasticity of pressurizing unit 27, described elasticity can preferably be higher than the elasticity of loam cake 6, and above-mentioned effect obtains as amplifying device.For example, representative padded coaming can be used, lid, sponge etc. can be used.
According to toilet seat apparatus 5 with said structure, as shown in Figure 5, in using toilet seat apparatus 5, when toilet seat apparatus 5 is installed on the toilet main body 22 and the weight of human body M when applying thereon by taking a seat, as mentioned above, piezoelectric transducer 9 is extruded.As a result, the vibration of moving according to human body M is exaggerated and is applied on the piezoelectric transducer 9, and the signal of telecommunication is exported with being stabilized.
Be supplied to control unit 13 according to the signal of telecommunication that acceleration of vibration provided.
But, sheltered by control unit 13 from the signal of telecommunication of piezoelectric transducer 9 output, thus make in the process of using toilet seat apparatus 5 by the vibration that drives generations such as washer jet, running hair-dryer or bath not can to the existence of human body whether, heart rate etc. constitutes noise.
As shown in Figure 6, control unit 13 is provided with unshowned filter circuit in control section 29, amplifying device, smoothing apparatus, determine device etc., and heart rate accountant 30 is installed, be used for calculating heart rate based on the output signal of smoothing apparatus, be used to show the display device 31 of heart rate accountant 30 output signals, be used for the calculating output of comparison heart rate accountant 30 and the comparison means 32 of setting value, and the warning generating means 33 that is used to give the alarm of result based on the comparison, the detection signal of piezoelectric transducer 9 outputs to control unit 13.
When piezoelectric transducer 9 detected the body kinematics of human body M and exports the signal of telecommunication, control unit 13 filtered the described signal of telecommunication by filter circuit, subsequently, amplifies the described signal of telecommunication by amplifying device, and by the level and smooth described signal of telecommunication of smoothing apparatus.As shown in Figure 7, that is sitting on the toilet seat apparatus 5 at human body M, is mounted thereon or moves when health when object constantly, big output waveform is output from smoothing apparatus.On the other hand, in the resting state after human body M sits thereon, the little body kinematics of the human body of propagating because of cardiac motion and respiratory movement, low relatively output waveform is output from smoothing apparatus.
Relative with it, when human body M does not exist or when object is mounted thereto, after the big output waveform of smoothing apparatus output, output waveform does not occur after the constant time period.
Therefore, determine that device compares output V and predetermined two setting values Va, the Vb of smoothing apparatus according to following, thereby determine.That is, when V＜Va, confirmable is that human body M or object do not exist (non-existence output H :).When Va≤V＜Vb, confirmable to be human body exist (exist output H :) with resting state.In addition, when Vb＜V, confirmable is that human body M produces body kinematics (body kinematics output H :).When object is installed in human body M present position, although to take a seat or health moves determines to carry out temporarily, but because the low degree of propagating by the effect or the Repiration of heart beating when human body M does not exist vibration can not occur, so by state that object is set determined that identifiable is that human body M does not exist.
When definite device determined that the people takes a seat, odor removal and heater began starting.When determining the people and do not exist, described operation stops.
In addition, described heater is handled the temperature control of heater 12.
In addition, when human body M sits thereon with resting state, because of the small-signal that the heart beating action is propagated is exported from described smoothing apparatus.Based on described signal, thereby calculate the output heart rate by heart rate accountant 30.Result of calculation is shown by the display device 31 as external monitor.In addition, as shown in Figure 6, control unit 13 is equipped with and is used for the comparison means 32 that output signal and predefined numerical value with heart rate accountant 30 compare, and being used for the alarm issue device 33 that the output by comparison means 32 gives the alarm, this device can give the alarm when heart rate is equal to or greater than setting value.Especially, when the people when draining firmly, heart rate increases and has the worry of cerebral hemorrhage occurring, control unit 13 helps healthy control by predicting this accident.In this case, when control unit 13 is connected by network in hospital etc., not only use the toilet seat apparatus 5 in hospital to be monitored, and the behavior in the lobby that can't directly be diagnosed always can be monitored by the concentrated area.
In addition, the signal that arrives display device 31 can be transmitted by non-wireless means or wireless device via communicator.
According to above-mentioned toilet seat apparatus 5, by will be, and be easy to detect very slight human motion according to the signal of telecommunication of acceleration of vibration stably to control unit 13 supplies, piezoelectric transducer 9 obtains high reliability thus.In addition, even because piezoelectric transducer 9 has flexible and also be difficult to thereon the time destroyedly impacting continuous action, and output is beneficial to the detection signal of difference people and object in addition, piezoelectric transducer 9 can stably detect taking a seat of people etc.
In addition, although according to the above embodiments, whether exist, heart rate etc. determined by the output signal that smoothly comes from piezoelectric transducer 9, can construct a kind of like this structure, wherein the output signal of piezoelectric transducer 9 is amplified as required, and be converted into numerical data by microcomputer etc. by the AD conversion subsequently, whether exist to be based on by described numerical data is carried out rolling average in described microcomputer definitely, perhaps heart rate size etc. is to calculate by the automatic correction factor that calculates numerical data.
Will summarize to the effect of the foregoing description.Described vibration detection device 34 forms by constituting a kind of like this structure, promptly near the pad 23 (standing part) that is used for toilet seat apparatus 5 is fixed in the toilet main body, support the piezoelectric transducer 9 (vibration detecting sensor) of the vibration that is used to detect the loam cake 6 (rigid body) that is sent to toilet seat apparatus 5 or substrate 7 (rigid body).
Thus, vibration is difficult near appearance pad 23 (shank (standing part)) most, and therefore near the piezoelectric transducer 9 that supports pad 23 (shank (standing part)) by projection 28 is prevented from vibration at described support section at least.Therefore, the vibration that is sent to loam cake 6 (rigid body) can accurately be detected in such environment, and wherein piezoelectric transducer (vibration detecting sensor) 9 is actually non-vibrating.
In addition, constitute a kind of like this structure, this structure comprises partly (standing part) 23 of four pads (lower limb), and near each pad support piezoelectric transducer (vibration detecting sensor) 9.
Thus, even when the function of constrained vibration is different in four pads (shank branch (standing part)) 23, the pad (shank branch (standing part)) that piezoelectric transducer 9 (vibration detecting sensor) is still had the maximum limit vibrating function supports, and therefore can accurately detect the vibration that is sent to loam cake (rigid body) 6.For example, bend over and its center of gravity when leaning forward, be understandable that when user, because the pad on rear side is not applied in too many body wt, vibration is difficult to be limited, also in this case, body wt is applied on the pad of front side, and therefore vibration can be limited.The result, when pick off is supported by all pads, the position of ignoring described center of gravity, need at least one or a plurality of by being applied in the pad that body wt can constrained vibration, therefore at described pad place, the vibration of piezoelectric transducer 9 (vibration detecting sensor) can be limited, and can accurately detect this vibration.By accident, when using the piezoelectric transducer that is cable-shaped in the present embodiment, even when having the standing part of a plurality of pads, described pick off can be made of the independent institute in them.
In addition, described piezoelectric transducer 9 (vibration detecting sensor) is formed on the side (on the side of loam cake) of the vibration source 6 of pad (standing part) 23.
Thus, the vibration of loam cake 6 can be detected in (on the side of loam cake 6) on the described side of vibration source, prevent the vibration of piezoelectric transducer 9 (vibration detecting sensor) on the described side of pad 23 (shank branch (standing part)) simultaneously, therefore the vibration that is sent to loam cake 6 can accurately be detected by simple structure, and is this simple in structure to the degree with pressurizing unit 27 and projection 28.
In addition, vibration detecting sensor constitutes by having certain flexible piezoelectric transducer 9.
Thus, when producing output when piezoelectric transducer 9 reception vibrations and according to described distortion, piezoelectric transducer 9 is easily deformable, therefore can accurately be exported according to the described output of vibrating.
In addition, in toilet seat apparatus 5 with vibration detection device 34, constitute a kind of like this structure, wherein rigid body is by toilet seat (loam cake 6, substrate 7) constitutes, described standing part is made of the pad that is connected to toilet seat lower surface 7 (substrate) (shank branch (standing part)) 23, and pad can contact by the upper surface with toilet main body 22 toilet seat is fixed, and the health vibration that is sent to the user of toilet seat is detected.
Therefore, the substrate 7 of toilet seat apparatus 5 is fixed in toilet main body 22 around pad 23, and is difficult to most be vibrated, and therefore near the piezoelectric transducer 9 (vibration detecting sensor) that can support support section prevents by pad 23 is at least vibrated.Therefore, the body kinematics of user that is sent to the loam cake 6 of toilet seat apparatus 5 in the present embodiment can accurately be detected, and wherein piezoelectric transducer 9 (vibration detecting sensor) does not in fact vibrate.
In addition, in toilet seat apparatus 5, constitute a kind of like this structure, its detection come from the taking a seat of user body kinematics, heart beating, breathing at least one of them.
Thus, based on the body kinematics that is accurately detected, be easy to detect the movable information of taking a seat, promptly whether user is sat thereon, or the bio information of the heart beating of user or breathing, realizes multi-functional toilet seat apparatus 5 by the detected information of full use.
In addition, will compare with Figure 11 simultaneously making an explanation in the inner example of vibration detecting sensor being installed and constituting standing part in the outside of rigid body of rigid body (toilet seat).
At first, Figure 21 illustrates the example of different structure.Figure 21 (a) is illustrated in the structure that the position is provided with pressurizing unit 27 and projection 28, and pressurizing unit 27 is configured to the skew of the left side of pad 23, and projection 28 is configured to the skew of the right side of pad 23.Figure 21 (b) illustrates a kind of structure, and this structure is used has the projection that flexible pressurizing unit 35 replaces rigid body, and the alignment of the right end position of pressurizing unit 27 and pressurizing unit 35, and their left position is offset each other.In addition, in this case, described pad 23 constitutes with the shape greater than pressurizing unit 27, pressurizing unit 25.In Figure 21 (c), piezoelectric transducer 9 (vibration detecting sensor) is set on the side near the loam cake 6 (rigid body) of pressurizing unit 36, and is directly fixed on loam cake 6 (rigid body) especially.In this case, constitute a kind of structure, wherein the whole top of piezoelectric transducer 9 vibrated according to loam cake 6, and only the vibration of the part of the lower surface of piezoelectric transducer 9 (by the part of pressurizing unit 36 extruding) is hindered.
Figure 22 illustrates some examples, and the shape on the surface of the pressurizing unit of piezoelectric transducer wherein respect to one another (vibration detecting sensor) differs from one another.In Figure 22 (a), recess 38 is formed on pressurizing unit 37.Naturally, ledge can be set.In Figure 22 (b), a plurality of pressurizing units 39 are set.In Figure 22 (c), pressurizing unit 40 is relative with the plane, and piezoelectric transducer 9 (vibration detecting sensor) is bent.
Figure 23 illustrates other example of rubber-like pressurizing unit.In Figure 23 (a), spring is as pressurizing unit 41.The pressurizing unit 42 of Figure 23 (b) has elasticity by thin spring material crooked and that fixedly be made of metal.
(embodiment 8)
According to present embodiment, will the example that vibration detecting sensor is installed between rigid body (bathtub) and standing part be made an explanation.
Figure 15 (b) is the structure chart that illustrates according to the bathtub device part of eighth embodiment of the invention, and Figure 24 is the cutaway view of the major part of Figure 15 (b).
Shown in Figure 15 (b), be provided with at the bathtub 43 of rigid body and have certain flexible piezoelectric transducer 45 that is wire as vibration detecting sensor between as the external frame 144 of standing part according to the bathtub device of the embodiment of the invention, described standing part overweights and is thicker than bathtub 43, and is difficult to transmit vibration.In addition, be provided for supporting from bathtub 43 be projected into the projection 46 of piezoelectric transducer 45 keeper 47, be in the piezoelectric transducer 45 of external frame (standing part) 144, and piezoelectric transducer 45 is positioned via the hole 48 of keeper 47.
Here, projection 46 and piezoelectric transducer 45 toward each other, their shape differs from one another.Can construct a kind of structure, wherein piezoelectric transducer 9 is longer on the left and right directions of Figure 24, and described projection 46 is longer on the depth direction of Figure 24, in addition, although piezoelectric transducer 9 has a flexure plane because of cable-shaped, piezoelectric transducer 9 is relative with it with constant shape on left and right directions, and described projection 46 is further given prominence to its core on left and right directions and constituted.Therefore, described piezoelectric transducer 45 is provided with part that does not contact with projection 46 and the part that contacts with described projection 46, in addition, with part that described projection 46 contacts in, to the part that is not subjected to too big extruding various parts with different pressured states can appear from the part (center) of powerful pressurized.From the above, the vibration of bathtub 43 is sent to piezoelectric transducer 45 via projection 46.
On the other hand, piezoelectric transducer 45 is installed to external frame 144 (standing part) via keeper 47.Constitute a kind of like this structure, wherein said external frame (standing part) 144 only contacts with bathtub 43 in its edge, even and when vibration appeared at bathtub 43 inside, vibration was not sent to external frame 144 (standing part).Therefore because external frame (standing part) 144 do not vibrate, so that part of being difficult to of supporting by the keeper 47 of piezoelectric transducer 45 vibrated.Therefore and since piezoelectric transducer 45 from the vibrations of the contacted surface reception of it and projection 46 bathtubs 43, keep simultaneously its with the surface that contacts of projection 46 at the state that is difficult to be vibrated, vibration can accurately be detected.Especially, the piezoelectric transducer 9 that uses in the present embodiment produces signal according to being provided to piezoelectricity composition distortion of materials acceleration, therefore do not vibrate and keeper 47 contacted surfaces by only vibrating projection 46, effectively the acceleration of contraction or stretching piezoelectricity composition distortion of materials can be received and can produce big output signal.
Now, present embodiment comprises having other structure of amplifying vibrating function.
The elasticity of piezoelectric transducer 45 at first, is provided.Described piezoelectric transducer 45 with flexible (flexural properties) also has elasticity, therefore come from vibration vibration piezoelectric transducer 45 itself with piezoelectric transducer 45 contacted projections 46, and the vibration that is different from especially, original vibration can be produced by the elasticity of piezoelectric transducer 45.That is, constitute a kind of like this mechanism, wherein in the output that the original vibration that is provided is provided, by the difference vibration that self produces by piezoelectric transducer 45, the output that has produced other.
Then, piezoelectric transducer 45 is mounted being applied under the tensile state.In Figure 24, piezoelectric transducer 45 is applying under the tensile state supportedly,, strains at piezoelectric transducer 45 that is.In this case, and piezoelectric transducer 45 is not applied tensile situation and compare, vibration is propagated far in piezoelectric transducer 45.When described piezoelectric transducer 45 is applied in to a certain degree tension force, come from and in piezoelectric transducer 45, propagated far with the vibration of piezoelectric transducer 45 contacted projections 46, as a result, described output can produce from the position the piezoelectric transducer 45.In view of the above, be understandable that, can obtain the effect identical, promptly realized amplifying described vibration with increasing transducer sensitivity.In addition, the tension force for preferably applying on the degree how preferably constitutes a scope, and wherein the mechanical strength of piezoelectric transducer 45 does not worsen at least, especially, is in and can keeps in the elastic scope.
Figure 17 (b) is illustrated in other example that vibration detecting sensor is installed between described rigid body (bathtub) and the standing part.
In Figure 17 (b), projection 49 is formed on the side of external frame 144, and keeper 47 is formed on the side of bathtub 43.
In addition, although according to the present invention, described bathtub is illustrated as described rigid body, and on viewpoint of history, described bathtub is made of various materials.Described material comprises timber, resin, stainless steel metal etc., marble, rock, tile etc.The rigid body that is used for bathtub can be suitable for, and is constituted as long as described rigid body is a material by the remarkable distortion that can not occur being felt by user in normal shower, vibrates and transmits in described rigid body.
In addition, for the external frame as standing part, although because external frame comprises the heavy and thick rigid body than bathtub, and external frame does not transmit vibration, what it is contemplated that is, formation not with the contacted external frame of bathtub.When external frame did not contact with bathtub, vibration can not be transmitted, and therefore, need not described materials limitations to not only heavily but also thick.

According to present embodiment, will the example of vibration detecting sensor being installed in the inside of rigid body and constituting the standing part of removable type in the outside of rigid body be made an explanation.Figure 18 (b) is the structure chart of shower, and it illustrates according to ninth embodiment of the invention, and Figure 25 is the cutaway view of the major part of Figure 18 (b).
According to the shower of the embodiment of the invention, shown in Figure 18 (b), described shower can use in the posture of taking a seat, and a people can use the hot water that sprays from a plurality of shower nozzles 51 to wash under the state that is seated at seat 150.It can be the center rotation with axle 153 with respect to shower main body 152 that seat 150 is formed, it can be the center rotation with axle 155 with respect to seat 150 that gripper shoe (standing part) 154 is formed, and gripper shoe be formed in use shown in Figure 18 (b) support by gripper shoe (standing part) 154 as described in seat 150, thereby and when not using by lifting seat 150 to parallel folding gripper shoe 154 with shower main body 152.
Vibration detection device 156 is integrated into the inside of the seat 150 of rigid body, described vibration detection device 156 comprise as the rubber-like of vibration detecting sensor in the form of sheets piezoelectric transducer 157 and as the rubber-like pressurizing unit 158 of amplifying device.As shown in Figure 25, even thereby when the shape on the surface of pressurizing unit 158 respect to one another and piezoelectric transducer 157 be flat when mutually the same, constitute by center and have the structure of chamber 159 at pressurizing unit 158, amplification effect has been exaggerated.The crimping section 160 and the crimping section 161 that is used to push piezoelectric transducer 157 under the situation of insertion chamber 159 of piezoelectric transducer 157 pushed in consideration in being used under the situation of not inserting chamber 159, piezoelectric transducer 157 is subjected to strong extruding from crimping section 160, but piezoelectric transducer 157 is subjected to weak extruding by crimping section 161, and this can be envisaged as and constitute a kind of structure that is similar to Figure 22 (a) and (b) function that has.
Promptly at piezoelectric transducer 157 places, there is the part of the brute force vibration that a reception produced by the brute force extruding of crimping section 160, and a part that does not receive too much by the little vibration that extruding produced of crimping section 161.The integral body of piezoelectric transducer 157 does not receive identical vibration, but piezoelectric transducer 157 has received the vibration different according to each several part, and described vibration equals the part distortion of piezoelectric transducer 157, so the output of piezoelectric transducer 157 can be enhanced.As a result, described piezoelectric transducer 157 can be deformed by the vibration of the rigid body (seat 150) that is difficult to be out of shape, and the vibration of rigid body (seat 150) has been exaggerated.As a result, pressurizing unit 158 can pass through cavity 159, crimping section 160,161 further amplifies vibration.
In addition, gripper shoe 154 is transmitted the load that is applied on the seat 150 via axle 155, therefore, constitutes a kind of like this structure, and wherein gripper shoe 154 is securely fixed between seat 150 and the bottom surface, and is difficult to be vibrated.In addition, constitute a kind of like this structure, wherein be connected to axle 155 bearing 162 and pressed on axle 155 forcefully, so bearing 162 is difficult to vibration, the result, the bottom surface of piezoelectric transducer 157 also is difficult to be vibrated.
Therefore, because the vibration of seat 150 is received from itself and pressurizing unit 158 contacted surfaces, keep the surface on bearing 152 1 sides to be in the state that is difficult to be vibrated simultaneously, piezoelectric transducer 157 can accurately detect vibration.
In addition, Figure 26 is illustrated in other example of vibration detecting sensor being installed and constituting removable type standing part in the outside of rigid body in the inside of rigid body (seat).
In Figure 26, provide and have different elastic first pressurizing unit (amplifying device) 163 and second pressurizing units (amplifying device) 164, be used for different vibrations is sent to the difference between each elasticity the surface of the piezoelectric transducer relative 157 with it as pressurizing unit.The integral body of piezoelectric transducer 157 does not receive identical vibration, but depends on that each several part piezoelectric transducer 157 receives different vibrations, and this is equivalent to the part distortion of piezoelectric transducer 157, and the output of piezoelectric transducer 157 can be enhanced.Described piezoelectric transducer 157 can be deformed by the vibration of the rigid body (seat 150) that is difficult to be out of shape, and the vibration of rigid body has been exaggerated.As a result, the elastic difference between the pressurizing unit 163 and second pressurizing unit 164 can be taken as the amplifying device that is used to amplify described rigid body (seat 150) vibration.In addition, the piezoelectric transducer 157 of present embodiment is with cable-shaped formation, but constitutes with lamellar, and this is to constitute by the both sides that will be connected to as the conductive rubber 166 of electrode by in the form of sheets the molded piezoelectric patches that forms 165 of piezoelectricity composition material.
(embodiment 10)
According to present embodiment, will to vibration detecting sensor is installed to rigid body (toilet seat) inner, constitute in the outside of rigid body standing part and not only near standing part but also the example that supports described vibration detecting sensor at the other parts place describe.
Figure 27 is the structure chart of a toilet seat apparatus, and wherein piezoelectric transducer 9 (vibration detecting sensor) is fixedly mounted in pad 23 (standing part) and is formed on the keeper 67,68 of the position between the pad.Figure 27 (a) illustrates the state that is not vibrated, and Figure 17 (b) illustrates a kind of like this state, and loam cake (rigid body) 6 wherein, substrate (rigid body) 7 are bent downwardly by vibration.Although loam cake 6 and substrate 7 are made of rigid body, be understandable that from microcosmic loam cake 6 and substrate 7 are bent as shown in the figure by the body kinematics of user.But described accompanying drawing is illustrated turgidly to be beneficial to understand, and in fact, described bending is the little bending on a certain degree, and in fact user can't be perceived.
Now, in Figure 27 (b), compare with Figure 27 (a), by being bent downwardly substrate (rigid body) 7, keeper 68 is pulled down, and keeper 67 is fixed by pad 23, so keeper 67 is difficult to be moved.Therefore, thus piezoelectric transducer 9 is pulled the amount that moves with downward distortion keeper 68.On the contrary, when substrate 7 was bent upwards by vibration, keeper 68 was lifted, thereby piezoelectric transducer 9 is upwards spurred distortion.When being produced by the body kinematics of user when moving up and down, piezoelectric transducer 9 is by being pulled with loose in corresponding time repeated deformation, and produces signal in view of the above.Look that the generation of signal can be implemented because described pick off not only be fixed on pad 23 (standing part) near, and be fixed on position between the pad.In addition, in this case, when coming from the pressurizing unit of loam cake 6 one sides, vibration also can be detected, and vibration detection device can be independent of loam cake 6 and constitutes.
Compare with shown in Figure 27, Figure 28 illustrate keeper 68 is formed at the example of loam cake 6 (rigid body) side and shown in Figure 28 (b) when being bent downwardly, keeper 68 is pulled down, and still, piezoelectric transducer 9 is tension but also be added into distortion on the shrinkage direction not only.That is, constitute a kind of like this structure, wherein deformation direction is opposite with the direction shown in Figure 27.
In addition, although in Figure 21, Figure 22, Figure 23, Figure 17 (b), Figure 25, Figure 26, between the pressurizing unit or gapped between projection and the piezoelectric transducer, be similar to Figure 11 (a), the simplification that is provided in gap is explained, the adding in described gap makes that in actual use two parts contact with each other just.

Fig. 1 is the decomposition diagram that illustrates according to the toilet seat apparatus of eleventh embodiment of the invention, Fig. 2 is the perspective view that is used in the outward appearance of the vibrating sensor in the toilet seat apparatus, Fig. 3 is to use the overall perspective view of the toilet of the toilet seat apparatus shown in Fig. 1, Figure 11 illustrates the major part cutaway view of the toilet seat apparatus of Fig. 1, Fig. 5 is the side view of the user mode of toilet shown in Figure 3, Figure 29 is the structured flowchart of control unit in the toilet seat apparatus, Fig. 7 is the time chart that pick off is exported and operated in toilet seat apparatus, Figure 30 illustrates the pick off output that is in when static, Figure 31 illustrates by the pick off of filter process and exports the signal that is constituted, Figure 32 is the feature block diagram by the automatic correction factor of the signal of filter process, and Figure 33 is the flow chart that is used to calculate the heart rate cycle.
As shown in Figure 1, the toilet seat apparatus 5 of embodiment according to the present invention is to have certain flexible piezoelectric transducer 9 and constitute as substrate 7 places that vibration detecting sensor is arranged on housing 8 by being wire, and described housing 8 comprises by the loam cake 6 of the resin molded rigid body that forms and substrate 7.
Here, as shown in Figure 2, the piezoelectric transducer that is wire 9 that uses is in the present embodiment described simply, pick off 9 is a kind of cable type pick offs that use piezoelectricity composition material, and by the heart yearn 18 (central electrode) that is arranged on the center in the axial direction, cover the piezoelectric 19 around the heart yearn 18, be arranged on piezoelectric 19 outer electrode 20 on every side, and PVC21 (Corvic) formation that is used to cover outermost.
In addition, compare with the polymer piezoelectric element, piezoelectric transducer 9 has hypersensitivity, and obtains extra high sensitivity at the low frequency region that is used for the human body heart rate (10Hz or lower).This be because since the dielectric constant (about 55) of piezoelectricity composition material 19 greater than the dielectric constant (about 10) of polymer piezoelectricity composition material, so even the minimizing of sensitivity also is little in low frequency region.
Not have the piezoelectricity function with the set piezoelectric transducer that is wire 9 of the molded mode of piezoelectricity composition material 19, therefore need to carry out certain and handle, be applied to piezoelectricity composition material 19 by high direct voltage and come to provide the piezoelectricity function for piezoelectricity composition material 19 with several kV/mm.After forming heart yearn 18 and lateral electrode 20, carry out polarization at piezoelectricity composition material 19 places and handle by between two electrodes 18,20, using DC voltage.
As shown in Figure 3, substrate 7 is equipped with 4 and is used to absorb ballistic pad 23, this pad 23 is attached on the rear surface of base plate 15, and when described toilet seat is similar to the device use of background technology, have by being arranged on absorption and toilet main body 22 ballistic elastic forces between toilet seat apparatus 5 and the toilet main body 22.In addition, toilet seat apparatus 5 is equipped with cap member 25, and cap member can be put forward a side to water tank 24 with toilet seat apparatus 5.
According to present embodiment, the piezoelectric transducer 9 that is wire is by being installed on the substrate 7 by a plurality of keeper 26 location and supports that are provided with that are separated from each other.
As shown in Figure 11, amplify pad 23, constitute a kind of structure, this structure comprises and being connected to as the rubber-like pressurizing unit 27 of the inner surface of the loam cake of rigid body and the projection 28 that is connected the rigid body on the substrate 7, and clips piezoelectric transducer 9 by pressurizing unit 27 and projection 28.Figure 11 (a) is illustrated in the state integrated before loam cake 6 and the substrate 7 and Figure 11 (b) state when loam cake 6 and substrate 7 screw threads are combined is shown.When user is sitting on the toilet seat apparatus 205, the state of Figure 11 (b) can appear naturally, and loam cake 6 and substrate 7 are made of rigid body, even make that toilet seat apparatus 5 can be not destroyed when body wt is applied in thereon yet.
Here, described rigid body is defined as a kind of like this parts, even just when people's body wt applies thereon at least, these parts also can not be out of shape and surpass its intensity, and especially, described rigid body is defined as a kind of like this parts, these parts make hip drop when the people sits thereon, the people does not feel distortion, promptly is a kind of like this parts, and promptly user can be not that intensity feels concern to these parts.Although described material is not restricted especially, can be insulant such as a kind of resin or pottery, perhaps can be metallic conductor etc., what replenished is that the toilet seat of background technology normally is formed from a resin.
Now, under user was sitting in situation on the toilet seat, total body wt of user was applied on the toilet seat, and still, loam cake 6 is owing to being to be difficult to partly be deformed by rigid body.But what can expect is that toilet seat integral body is vibrated by the body kinematics of user, although this vibration is slight.Thereby how lower surface will be exaggerated the vibration of toilet seat and be transferred to piezoelectric transducer 9 and provide detailed explanation.
At first, because pressurizing unit 27 is set between loam cake 6 and the piezoelectric transducer 9, therefore, pressurizing unit 27 is vibrated because of the vibration of loam cake 6, and still, the feature of described vibration is very complicated.Because loam cake 6 is made of rigid body, pressurizing unit 27 is rubber-like parts, therefore the top of pressurizing unit 27 (be connected to loam cake 6 that part of near) is similar to loam cake 6 and vibrated, near the bottom of pressurizing unit 27 (be connected to piezoelectric transducer 9 that part of) vibration a little tardily is to repeat to be different from the vibration of loam cake 6.Therefore, piezoelectric transducer 9 not only is transmitted the different vibrations that have each pressurizing unit 27 to bring as the vibration of the loam cake 6 of rigid body and substrate 7 but also transmission, and pressurizing unit 27 amplifies the what is called vibration of loam cakes 6.Therefore, pressurizing unit 27 can be considered to a kind of amplifying device.
Then, pressurizing unit 27 and piezoelectric transducer 9 are with configurations differing from one toward each other.In the structure that is constituted, piezoelectric transducer 9 is longer on the left and right directions of Figure 11, and pressurizing unit 27 is bigger on the depth direction of Figure 11, piezoelectric transducer 9 because of cable-shaped with curved surface with respect to pressurizing unit 27, and pressurizing unit 27 is with respect to a plane.Therefore, in piezoelectric transducer 9, have part that does not contact and the part that contacts with pressurizing unit 27 with pressurizing unit 27, and with part that pressurizing unit 27 contacts in, to the inapparent part of extruding, exist various parts from the part of brute force extruding with different squeezed states.Therefore, piezoelectric transducer 9 receives and depends on the vibration that each several part is different, make the part place that contacts with pressurizing unit 27 not, the piezoelectric transducer 9 main vibrations that receive rigid body, and at the part place by pressurizing unit 27 powerful extruding, the vibration that is different from described rigid body that piezoelectric transducer 9 main receptions are produced by pressurizing unit 27.Piezoelectric transducer integral body does not receive identical vibration but receives because of the different vibration of each several part, and this vibration is equal to the part distortion of piezoelectric transducer 9, so the output of piezoelectric transducer can increase.As a result, piezoelectric transducer 9 is deformed because of the vibration that comes from the rigid body that is difficult to be out of shape, and therefore the vibration of described rigid body is exaggerated.Therefore, the difference between the shape of the face of pressurizing unit 27 respect to one another and piezoelectric transducer 9 can be considered for a kind of amplifying device.
Then, projection 28 and piezoelectric transducer 9 are faced mutually with configurations differing from one.Thus, in piezoelectric transducer 9, have part that does not contact and the part that contacts with projection 28 with projection 28.Therefore, piezoelectric transducer 9 receives vibration or does not receive vibration according to described each several part, make the part that contacts with projection 28 not, the reception that piezoelectric transducer 9 is exceeded is as the vibration of rigid body, and in the part that contacts with described projection 28, piezoelectric transducer 9 promptly is similar to the vibration of substrate 7 or loam cake (rigid body) 6 by the vibration that projection 28 receives as rigid body.But the integral body that the integral body of piezoelectric transducer does not receive identical vibration piezoelectric transducer receives vibration or does not receive vibration according to each several part, and this equals piezoelectric transducer 9 and partly is out of shape, so the output of piezoelectric transducer can be increased.As a result, piezoelectric transducer 9 can be deformed by the vibration that comes from the rigid body that is difficult to be out of shape, although distortion is slight, the vibration of described rigid body is exaggerated.Therefore, the difference between the shape on the surface of projection 28 respect to one another and piezoelectric transducer 9 can be considered for a kind of amplifying device.But the amplification effect that projection 28 is caused is less than the amplification effect of aforesaid pressurizing unit 27.
Below, pressurizing unit 27 and projection 28 are faced mutually with configurations differing from one, and particularly, the area of pressurizing unit 27 is bigger.Because projection 28 is rigid bodies, only has the core of pressurizing unit 27 to be compressed, and is hindered in the elasticity of the core pressurizing unit 27 that compresses, carry out vibration near the rigid body vibration.In addition, power is applied in piezoelectric transducer 9 by pressurizing unit 27 and projection 28, and piezoelectric transducer 9 is fixed to a certain extent.The size of power also can be by pressurizing unit 27 elasticity and when loam cake 6 and substrate 7 combine the distance between them be changed.When the elasticity of pressurizing unit 27 is low or the distance between loam cake 6 and substrate 7 in short-term, piezoelectric transducer 9 is further applied described power and is firmly fixed.On the other hand, the side (part not relative) around pressurizing unit 27 with projection 28, described elasticity is kept, and therefore the vibration that can be different from rigid body of described side is vibrated.Therefore, core at pressurizing unit 27, piezoelectric transducer 9 is fixed and approaches the vibration that rigid body vibrates, and the side around pressurizing unit 27 (not relative with projection 28 part), piezoelectric transducer 9 is carried out the vibration that only is different from the rigid body vibration of being pushed by pressurizing unit 27.In this case, it should be noted that oscillating component that approaches rigid body vibration and the oscillating component that is different from described rigid body vibration are set at position very close each other in the piezoelectric transducer 9.Receive different each other vibrations at very close each other position piezoelectric transducer 9, this equates piezoelectric transducer 9 and be out of shape partly, so the output of piezoelectric transducer can be increased.As a result, piezoelectric transducer 9 can be come from the vibration of the rigid body that is difficult to be out of shape and is out of shape, although the distortion that is caused is little, therefore the vibration of described rigid body is exaggerated.Thus, the difference between the shape of the face of pressurizing unit 27 respect to one another and projection 28 can be considered for a kind of amplifying device.Here, projection 28 may not be a rigid body.Even when projection 28 is made of elastomer, height that can be by increasing projection 28 or shorten distance between loam cake 6 and the substrate 7 compresses described pressurizing unit 27 forcefully and hinders described elasticity in the central part office.
Here, for the elasticity of pressurizing unit 27, described elasticity can be higher than the elasticity of loam cake 6, and obtains the above-mentioned effect as amplifying device.For example, representational gasket part can be used, perhaps rubber or sponge can be used.As shown in Figure 5, in using described toilet seat apparatus, when the toilet seat apparatus 205 with above-mentioned structure is set on the toilet main body 22, and the weight of human body M is when being applied in thereon by taking a seat, as described above, piezoelectric transducer 9 is extruded.As a result, the vibration of moving corresponding to human body M is exaggerated, and is applied on the piezoelectric transducer 9, and the signal of telecommunication is exported with being stabilized.
The signal of telecommunication according to acceleration or vibration setting is supplied to control device 213.
But, when using toilet seat apparatus 5, sheltered by control unit 213 from the signal of telecommunication of piezoelectric transducer 9 output, thus make by drive washer jet as cleaning device, operation as the vibration of generations such as the hair-dryer of drying device or bath not can to the existence of human body whether, heart rate etc. constitutes noise.
As shown in Figure 29, the inside of control device 213 comprises and is used for determining first definite device 229 of body motion information and is used for second of definite bio information determining device 230.
First determines that device 229 is constituted as the output that receives piezoelectric transducer, signal processing apparatus 233 by having filter 231 and amplifying device 232 is handled the output signal of piezoelectric transducers, based on the movable information (people how to operate) of described signal by movable information accountant 234 calculating people.Here, external power source part 235 is supplied electric energy via electric supply installation 236 to signal processing apparatus 235, and always waits for the vibration that body kinematics produced by human body.
Second determines that device 230 is constituted as the signal that reception comes from signal processing apparatus 233, handle described signal by signal processing apparatus 239, calculate people's bio information (heart beating, breathing etc.) based on described signal by bio information accountant 240 with filter 237 and amplifying device 238.Here, external power source part 235 is supplied electric energy via electric supply installation 236 to signal processing apparatus 235, and when the switch 241 of electric supply installation 236 was the pass, the power supply that is fed to signal processing apparatus 239 was cut off, and can't determine bio information.
When not in use, only determine device 229 by first, switch 241 is configured to close the vibration that produces by human motion to wait for.In addition, when using by the people, this user needs to carry out the motion of " lifting cap member 225 " and the motion of " being sitting in toilet seat apparatus 205 ", so the vibration of lifting cap member 225 and the big vibration that is sitting on the toilet seat apparatus 205 produce on toilet seat apparatus 205.Therefore, the state that vibration never appears in piezoelectric transducer 9 dynamically sharply changes to the state that receives big vibration, and therefore, the displacement acceleration is that big and big output produces from here.The big output of piezoelectric transducer 9 is sent to movable information accountant 234 as the signal based on the movable information that is produced by filter 231 and amplifying device 232, as a result, first definite device 229 has determined to occur the motion of " lifting cap member 225 " and the motion of " seat is on toilet seat apparatus 205 " etc.In addition, after determining that by first device 229 is determined " seat is on toilet seat apparatus 205 ", control device 213 opens switch 241 by electric supply installation 236.Then, electric energy also is supplied to signal processing apparatus 239, therefore signal processing apparatus 239 receives the signal that comes from signal processing apparatus 233, by filter 237 and amplifying device 238 etc. described signal is handled in addition, and communicated the signals to bio information accountant 240.In addition, when user is static, stop at short notice by the motion of previous " lifting cap member 225 " and the big vibration that motion produced of " seat is at toilet seat apparatus 205 ", the weak vibration of only with good grounds user bio information subsequently, i.e. heart beating, breathing etc. can continue.Although the vibration according to described bio information is weak, therefore the output of piezoelectric transducer 9 is little, described output is as being sent to bio information accountant 240 at the amplifying signal via two-stage amplifying device 232,238, and therefore described output can be used as the signal with sizes related and handled by biological computation device 240.In addition, even in identical bio information, for because of the vibration of heart beating and the vibration because of breathing, the frequency of heart beating is high and frequency that breathe is low, so both can be by filter 237 separately.In this case, as the structure that detects heart beating, in the inside of bio information accountant 240, the heart rate cycle is calculated by calculating automatic correction factor, thereby calculates heart rate.In addition, the display device 244 that was used to show as calculated the heart rate of crossing is installed, the comparison means 243 that is used to calculate described heart rate Yu preestablishes heart rate numerical value, and be used for the notifying device 244 that result based on the comparison gives the alarm.Described notifying device 244 gives the alarm when described heart rate is equal to or greater than setting value.Especially, when the people when draining firmly, heart rate increases and has worry to cerebral hemorrhage, but control device 293 can help healthy control by the attack that prediction comes from changes in heart rate.In this case, when control device 293 is connected in such as hospital etc. by network, not only use toilet seat apparatus 205 in hospital to be concentrated and monitor, and the behavior in the lobby that can't directly be diagnosed also always can be monitored.
In addition, the signal that arrives display device 242 can be transmitted by limited device or wireless device via communicator.
Here, for the first definite device that is used for determining movable information, when paying close attention to the output size of signal processing apparatus 233, as shown in Figure 7, be sitting on the toilet seat apparatus 205 at human body M (or stand at human body M that constantly) or when the object of cap member etc. be mounted thereon (or when object be removed) even or that moment when human body is moved in human body M maintenance seat state thereon, big output waveform is output.On the other hand, when resting state occurring after sitting thereon at human body M, because the little body kinematics of the human body that the action of heart or Repiration are propagated, low level relatively output waveform is output.
In contrast be that when human body M does not exist, or when object is mounted thereon, output waveform constant time period behind the big waveform of output does not occur.
Therefore, the output V of signal processing apparatus 233 and previous two data Va that determine, Vb can compare and be determined by following.That is, when V＜Va, confirmable is that human body M or object do not exist (non-existence output H :).When Va≤V＜Vb, confirmable to be human body exist (exist output H :) with resting state.In addition, when Vb＜V, confirmable is that human body M produces body kinematics (body kinematics output H :).When object is installed in human body M present position, although to take a seat or health moves determines to carry out temporarily, because the low-level vibration of propagating by the effect or the Repiration of heart beating when human body M does not exist can not occur, so by state that object is set determined that confirmable is that human body M is non-existent.
In addition, when first determined that device is determined existing of people, odor removal and heater began starting.When determining the people and do not exist, described operation stops.In addition, the toilet seat heater is described heater 12.
On the other hand, for the second definite device that is used for determining bio information, heart beating is to obtain from the output variation of Fig. 7 so-called quiescent time.In fact, the output waveform of the piezoelectric transducer in quiescent time 9 as shown in figure 30.
Now, in signal processing apparatus 239, filter 237 is a kind of low pass filters, it has the cut-off frequency of the 30Hz that is used for eliminating the 60Hz noise component(s) especially, and be a kind of high pass filter, it has the cut-off frequency that is used for especially eliminating by the 0.5Hz that breathes the oscillating component that is produced.Figure 31 is illustrated in by the output waveform behind the filter 237.
Below, in bio information accountant 240, at first, calculate 0 to t
MaxAutomatic correction factor between second.Figure 32 illustrates the example through the automatic correction factor that calculates.
Then, determine the cycle based on the automatic correction factor F (t) that is calculated.Figure 33 illustrates the operation of calculating the described cycle with flow chart.Operation is detected by peak value and constitutes.
When from 0 with hour between cycle dt when increasing t, from step 2 to step 4, determine the minimizing among the F (t), and determine the increase the F (t) from step 5 to step 7.T and F (t) are stored in step 8 after finishing described increase.By the repeating said steps detection peak, t becomes t up to traveling time
Max, and after finishing detection, in step 9, the peaked t of indication is restricted to the described cycle in peak value.According to the data of Figure 32, the described cycle is t1 second.Below, calculate heart rate.Can calculate heart rate from the cycle that calculates, described heart rate is S=60/t1.In described data instance, S=60/t1.As mentioned above, in bio information accountant 240, calculate heart rate S.
By accident, according to present embodiment, the amplification coefficient of amplifying device 232 can be configured to 10, and the amplification coefficient of amplifying device 238 can be configured to 200.
In addition, first determines that device can be used as input equipment wittingly by user, described input equipment be used to the to advance controlled step of toilet seat apparatus 205.
For example, as the general function of toilet seat apparatus 205, after drainage, wash by water or blow out exsiccant wind.But in this case, described operation need not to carry out with corresponding time cycle or quantity.For example, quite difficult degree or detection degree of drying by detection cleaning buttocks stops cleaning, therefore stops and starting by controlling continually with predefined cycle average time driving toilet seat apparatus 205 or by compressing switch under the user.
Therefore, be understandable that, by determining that by first the movable information that device detects such as " shaking buttocks " controls start and stop.Possible is drains the back and stops the user that is sitting on the toilet when shaking by finishing when buttocks, and water for cleaning begins flushing, and when buttocks shook continuously, water for cleaning stopped flushing, begins to blow out dry wind, then, when buttocks shakes, stopped to blow out dry wind.According to described method, therefore user can, can be eliminated because of time cycle and the not enough bad sensation that causes of quantity with preferred time cycle and quantity cleaning and dry buttocks, and can prevent that time cycle and quantity from too much causing waste.In addition, and compare with the operation of hands by soft-touch control, hands need not touch Anywhere, and therefore, this operation is the cleanest.

Figure 15 (c) is the structure chart that illustrates according to the cross section of the bathtub device of twelveth embodiment of the invention, and Figure 34 is the structured flowchart of the control device in the bathtub device.
Shown in Figure 15 (c), be equipped with the bathtub 246 that is in rigid body and cover according to the bathtub device of the embodiment of the invention and have certain flexible piezoelectric transducer 248 that is wire between 247.In addition, described bathtub device comprises the projection 249 of giving prominence to piezoelectric transducer 248 from bathtub 246, and is used for by covering the keeper 250 of 247 support piezoelectric transducers 248, and described piezoelectric transducer 248 is positioned via described keeper 250.
Here, projection 249 and piezoelectric transducer 248 toward each other, their shape differs from one another.Can construct a kind of structure, wherein piezoelectric transducer 248 is longer on the paper direction that is parallel to Figure 15 (c), and described projection 29 is longer on the depth direction of Figure 15 (c).Therefore, described piezoelectric transducer 248 has part that does not contact with projection 249 and the part that contacts with described projection 249, in the part that contacts with described projection 249, to the part that is not subjected to too big extruding various parts with different pressured states can appear from the part (center) of powerful pressurized.
Except described here, although piezoelectric transducer 248 is connected to via keeper 250 and covers 247, but state is by described lid 247 overall fixed bathtub 246 whether, and whether lid 247 is made of rigid body or elastomer, and whether keeper 250 is made of rigid body or elastomer and changes to some extent.
At first, when lid 247 is not integrated when not being fixed in bathtub 246, regardless of covering 247 the material or the material of keeper 250,, cover 247 and do not vibrated although bathtub 246 is vibrated by the body kinematics of user.The vibration of bathtub 246 only is sent to piezoelectric transducer 248 from projection 249, therefore, is only vibrated with the part of projection 249 contacted piezoelectric transducers 258, and does not vibrate with projection 249 contacted parts.The integral body of piezoelectric transducer 248 does not receive identical vibration, but piezoelectric transducer 248 has received the vibration different according to each several part, and described vibration equals the part distortion of piezoelectric transducer 248, so the output of piezoelectric transducer 248 can be enhanced.As a result, described piezoelectric transducer 248 can be deformed by the vibration of the bathtub 246 (rigid body) that is difficult to be out of shape, so the vibration of bathtub (rigid body) 246 has been exaggerated.Thus, can be construed to be a kind of amplifying device to the shape of the face of projection 249 respect to one another and piezoelectric transducer 248.
Below, when lid 247 is fixed in bathtub 246 with being integrated and covers 247 and keeper 250 when one of them is made of elastomer at least, bathtub 246 is vibrated because of the body kinematics of user, and carries out the vibration that is different from bathtub 246 because of the vibration that flexible member brought via the vibration of lid 247 and keeper 250.Although the vibration of bathtub 246 is sent to piezoelectric transducer 248 from projection 249, also have vibration to be sent to piezoelectric transducer 248 via lid 247 and keeper 250, thus piezoelectric transducer 248 receive because of with projection 249 contacted parts and with the different vibration of keeper 250 contacted parts.The integral body of piezoelectric transducer 248 does not receive identical vibration, but piezoelectric transducer 248 has received the different vibration of each several part, and described vibration equals the part distortion of piezoelectric transducer 248, and therefore the output of piezoelectric transducer 248 can be enhanced.As a result, described piezoelectric transducer 248 can be deformed by the vibration of the bathtub 246 (rigid body) that is difficult to be out of shape, and therefore, the vibration of bathtub (rigid body) 246 has been exaggerated.Thus, projection 249, lid 247, keeper 250 can be considered to constitute a kind of amplifying device.
At last, lid 247 be fixed in described bathtub 246 with integrating and cover 247 and keeper 250 situation about constituting by rigid body under, when bathtub 246 is vibrated by the body kinematics of user, look described that vibration is sent to piezoelectric transducer 248 from projection 249, and be to constitute with the vibration of keeper 250 by identical vibration via lid 247.But, from microcosmic, existing difference in a way between them, promptly this difference can't be determined by the people.That is, when bathtub 246 vibrations, projection 249 is vibrated at once, and still, keeper 250 can not vibrate immediately.After bathtub 246 vibrations, lid 247 is vibrated by being connected to bathtub 246 part on every side, and further vibration of keeper 250 beginnings subsequently.That is, the path of transmission vibration is longer.Therefore, piezoelectric transducer 248 receive because of with projection 249 contacted parts and with the different slightly vibration of keeper 250 contacted parts.The integral body of piezoelectric transducer 248 does not receive identical vibration, but piezoelectric transducer 248 has received the different vibration of each several part, and described vibration equals the part distortion of piezoelectric transducer 248, and therefore the output of piezoelectric transducer 248 can be enhanced.As a result, described piezoelectric transducer 248 can be deformed by the vibration of the bathtub 246 (rigid body) that is difficult to be out of shape, so the vibration of bathtub (rigid body) 246 has been exaggerated.Therefore, projection 249, lid 247, keeper 250 can be construed to constitute a kind of amplifying device.But in this case, enlarging function is less than the enlarging function in the above-mentioned situation, so the circuit of processes sensor output need be designed to increase amplification coefficient.
Now, present embodiment comprises other structure with enlarging function.
At first, described structure comprises the elasticity of described piezoelectric transducer 248.Described piezoelectric transducer 248 with flexible (flexural properties) also has elasticity, therefore described piezoelectric transducer 248 itself can be vibrated by the vibration of the projection 249 that keeps in touch with piezoelectric transducer 248 and the vibration that comes from keeper 250, especially, this vibration is different from the original vibration that elasticity produced by piezoelectric transducer 248.That is, constitute a kind of like this mechanism, wherein in the output that produces with respect to the original vibration that is provided, other output still can produce by itself carrying out different vibrations by piezoelectric transducer 248.
Below, piezoelectric transducer 248 is mounted in being applied in certain tensile state.In Figure 15 (c), piezoelectric transducer 248 is supported in being applied in described tensile state, promptly is in the state that is strained at.In this case, be not applied in described tensile situation with piezoelectric transducer 248 and compare, the vibration in piezoelectric transducer 248 is by long-distance communications.When the tension force that applies in a way, come from the projection 249 that contacts with piezoelectric transducer 248, the vibration of keeper 250 is propagated fartherly in piezoelectric transducer 248, the described output of result can produce from all places in piezoelectric transducer 248.It can be seen, obtained and the identical effect of sensitivity that increases pick off, promptly amplify vibration.In addition, about preferably applying the how tension force of degree, preferably constitute a scope, wherein the mechanical strength of piezoelectric transducer 248 can not degenerated at least, particularly in can keeping elastic scope.
As shown in Figure 34, comprise that in the inside of control device 251 first determines that device 252 and second definite device 253, the first definite devices 252 are used for determining the movable information of human body, second determines that device 253 is used for determining bio information.
First determines that device 252 is constituted as the output that receives piezoelectric transducer 248, signal processing apparatus 256 by having filter 254 and amplifying device 255 is handled the output signal of piezoelectric transducers 248, is calculated people's movable information (how the people operates) by movable information accountant 257 based on described signal.In addition, external power source part 258 is supplied electric energy via electric supply installation 259 to signal processing apparatus 256, and can be by the ON/OFF of switch 260 control power supplys.When the switch 260 of electric supply installation 259 was out, described signal can be supplied to signal processing apparatus 256 by the supply electric energy, and movable information can be determined by movable information accountant 257.When the switch 260 of electric supply installation 259 is when closing, the electric energy that is fed to signal processing apparatus 256 is cut off and can't determines movable information.
Second determines that device 253 is constituted as the output that receives piezoelectric transducer 248, signal processing apparatus 263 by having filter 261 and amplifying device 262 is handled the output signal of described piezoelectric transducer 248, is calculated people's bio information (heart beating, breathing etc.) by bio information accountant 264 based on described signal.Here, external power source part 265 is supplied electric energy via electric supply installation 266 to signal processing apparatus 263, and controls the ON/OFF of power supplys by switch 267.When the switch 267 of electric supply installation 266 was out, described signal can be processed by supplying electric energy to signal processing apparatus 263, and can determine bio informations by bio information accountant 264.When the switch 267 of electric supply installation 266 was the pass, the electric energy that is fed to signal processing apparatus 263 was cut off, and bio information can't be determined.
Following control is by expecting based on above-described control device 251.Although when not using, two switches the 260, the 267th, close and do not wait for movable information and bio information, but a kind of like this state can occur, promptly, wait for movable information by only switch 260 being switched to out and filling hot water or finish the heating bathtub to bathtub in conjunction with finishing automatically.When the people is mobile in bathtub 246, based on good moving being created in the bathtub 246 of the motion of " in bathtub 246 move ".Therefore, piezoelectric transducer 248 vibrational state dynamically never occurs and changes to the state that receives big vibration, and therefore the acceleration of distortion is big and has produced big output.The big output of piezoelectric transducer 248 is sent to operation information accountant 257 by filter 254 and amplifying device 255 as the signal of movable information, the result, and first determines that device 252 determined to occur the operation of " moving " in bathtub 246.In addition, afterwards, control device 251 leaves switch 267 by electric supply installation 266 determining to determine to have occurred " moving " by device 252 in bathtub 246 by first.Then, electric energy also is supplied to signal processing apparatus 263, described signal processing apparatus 263 receives the signal that comes from piezoelectric transducer 248, further handles described signal by filter 261, amplifying device 262 etc., and communicates the signals to bio information accountant 264.In addition, when user kept static, the big vibration that the motion formerly of " moving in bathtub 246 " is produced stopped at short notice, after this, the weak vibration of only with good grounds user bio information, i.e. heart beating, breathing etc. can continue.Because the vibration according to bio information is weak, the output of piezoelectric transducer 248 is weak, but, described output is as being sent to bio information accountant 264 by 262 amplifying signals of amplifying device, therefore, described output can be used as the signal that has quite size and is handled by described bio information accountant 264.In addition, although identical bio information, the vibration that produces for heart beating and breathe the vibration that produces, the frequency of heart beating is higher and frequency that breathe is lower, so both can be by wave filter 261 etc. separately.Here, for example, the rising of blood pressure or blood torrent can determine that to the degree of bather's head water supply installation 268 can be controlled by determining that the hypsokinesis removing water retention by purgation is to reduce the temperature of hot water by the bio information of heart beating, breathing etc.In addition, in the time can determining some bathers by bio information, the danger of being drowned can be avoided to the household danger reporting by the notifying device 269 usefulness radio communications that are arranged on other room in advance.
In addition, first determines that device can be used as the control input equipment of bathtub device wittingly by user.
For example, as the general function of bathtub device, carry out automatic hot-water filling, extra heating, the hot water that comes down in torrents, generation has the steam bubble that loosens effect, or ventilates, drying, cooling and heating bathroom etc.In addition, usually, the bather controls various functions by switching manipulation.
