Description

The present invention relates to a bath device capable of disinfecting hot water in a bathtub.

Specific examples of the conventional bath device are those described in Patent Documents 1 to 3.
The bath device described in the same document is provided with a sterilization device for sterilizing hot water in a bathtub, and this sterilization device includes a hot water distribution unit in which hot water in the bathtub can flow in and out, and this hot water distribution unit. It is configured in combination with a disinfectant lamp that can irradiate ultraviolet rays toward the hot water. The sterilization device operates when a predetermined switch operation is performed by the user, or when a timer is set in advance by the user, and the sterilization of the hot water is performed by irradiating the hot water in the bathtub with ultraviolet rays. Be done.

Here, in Patent Documents 1 and 2, the sterilization ability is made variable as a means for making the hot water in the bathtub as clean as possible, and when the hot water is extremely dirty, the sterilization ability is made higher than usual. I try to make it higher. On the other hand, in Patent Document 3, when the bath agent is added to the hot water of the bathtub, the sterilizing ability is enhanced as compared with the case where the bath agent is not added.

However, in the above-mentioned prior art, there is room for improvement as described below.

That is, when an opaque bath salt is added to the hot water of the bathtub, the water-insoluble component contained in the bath salt makes the hot water turbid, and the turbidity of the hot water becomes considerably high. Be hindered. As a result, as in Patent Document 3, when a bath agent is added, it is difficult to efficiently irradiate hot water with ultraviolet rays even if an attempt is made to enhance the sterilizing ability, and the sterilizing effect is hardly obtained. There are many. Further, in Patent Documents 1 and 2, when the turbidity of the hot water is high regardless of whether or not the bath agent is added to the hot water of the bathtub, an attempt is made to increase the sterilization ability, but the turbidity is high. If it is considerably high, it is not possible to efficiently irradiate the hot water with ultraviolet rays as in the case where the bath salt described above is added, so that a situation occurs in which the sterilization effect is hardly obtained.
On the other hand, in order to sterilize hot water, in addition to driving the sterilization lamp to light up, it is necessary to drive a pump for sending hot water from the bathtub to a predetermined hot water distribution section.
Therefore, it is unreasonable to try to increase the sterilizing ability of the sterilizing device considerably more than usual even though the turbidity of the hot water is quite high and the sterilizing effect is hardly obtained, and the power consumption is consumed. And a lot of wasted time. In addition, the service life of disinfectant lamps and pumps is shortened.

Japanese Unexamined Patent Publication No. 9-26207 Japanese Unexamined Patent Publication No. 9-276622 Japanese Unexamined Patent Publication No. 2001-12452

The present invention was conceived under the above-mentioned circumstances, and is caused by the fact that a bath agent is added to the hot water while appropriately having a sterilizing function of the hot water in the bathtub. An object of the present invention is to provide a bath device capable of appropriately avoiding a problem that a large amount of waste of power consumption occurs when the turbidity of the hot water is considerably high.

In order to solve the above problems, the following technical measures are taken in the present invention.

The bath device provided by the first aspect of the present invention includes a hot water distribution section through which hot water in a bathtub can flow in and out, and a disinfectant lamp capable of irradiating the hot water in the hot water distribution section with light for disinfection. A bath device having a sterilization device and a control means for executing control to operate the sterilization device at a predetermined sterilization start scheduled time, and the turbidity of hot water in the bathtub is equal to or higher than a predetermined value. Further, the control means is provided with a turbidity detecting means capable of determining whether or not the turbidity is, and when the turbidity of the hot water is equal to or higher than a predetermined value, the predetermined sterilization start scheduled time has arrived. However, it is characterized in that it is configured so as not to operate the sterilization device.
Here, the turbidity referred to in the present invention is the degree of turbidity of hot water, and may not conform to the definition and unit specified in JIS. The degree of turbidity of the hot water may be objectively indicated in some way, and for example, the translucency, the absorbance, the reflectance, or similar values of the hot water can be used. Further, the turbidity does not have to be an absolute value, and may be expressed as a relative value with respect to a predetermined hot water, for example.

According to such a configuration, the following effects can be obtained.
That is, when the turbidity of the hot water is considerably high due to the fact that the bath salt is added to the hot water of the bathtub, the sterilization device is not operated, so that the sterilization effect is almost obtained. It is rational because it can eliminate waste such as consuming a lot of power and time even though it does not exist. In addition, it is possible to prevent the service life of the disinfectant lamp from being unnecessarily shortened, and if a configuration is adopted in which hot water in the bathtub is supplied to the hot water distribution section of the disinfectant device using a pump, this is used. It is also possible to prevent the service life of the pump from being unnecessarily shortened.
On the other hand, when the turbidity of the hot water in the bathtub is low, the sterilization device operates as usual, so that it is possible to properly sterilize the hot water in the bathtub and make the hot water hygienic. ..

In the present invention, preferably, when the turbidity of the hot water is not more than a predetermined value and the sterilization device is operated, when the turbidity of the hot water is high, the degree of sterilization treatment is increased as compared with the case where the turbidity is low. It is configured as follows.
Here, as means for increasing the degree of sterilization treatment, for example, increasing the intensity of the sterilization light emitted from the sterilization lamp, lengthening the sterilization treatment time, and the flow velocity of hot water in the hot water distribution section. For example, slowing down.

According to such a configuration, it is possible to perform the optimum or near-optimal sterilization treatment without waste depending on the turbidity of the hot water in the bathtub.

In the present invention, preferably, the turbidity detecting means receives the disinfectant lamp and the light emitted from the disinfectant lamp and transmitted through the hot water, or receives the light reflected by the hot water, and the amount of received light thereof. It is configured by combining a light receiving element that outputs a signal of the corresponding level.

With such a configuration, it is possible to accurately determine the turbidity of hot water based on the level of the signal output from the light receiving element, but since a disinfectant lamp is used as the light source, it is turbid. There is no need to use a separate light source dedicated to turbidity measurement. Therefore, it is possible to suppress an increase in manufacturing cost and running cost.

In the present invention, preferably, the control means measures the turbidity of the hot water in the bathtub or a corresponding value at a predetermined first time during the filling of the bathtub or after the completion of the filling. , Using this measured value as a reference value, and at a predetermined second period after a person has entered the bathroom, and / or at a predetermined third period after a person has bathed in the bathtub. , The turbidity of the hot water in the bathtub or a value corresponding thereto is further measured, and the turbidity of the hot water is determined based on the measured value and the reference value.

According to such a configuration, the predetermined first time during or after the bathtub is filled with hot water is considered to be the time when the bath salt has not been added yet, and was measured at this first time. Since the turbidity of the hot water is determined based on the turbidity of the hot water as a reference value, it is preferable for accurately determining whether or not the bath salt has been added. In particular, during the predetermined second period after a person has entered the bathroom and / or the predetermined third period after a person has entered the bathtub, the bath salt is added to the hot water of the bathtub. It is more preferable because it is after the time when it is likely to be introduced.

In the present invention, preferably, the remote controller and / or the communication terminal capable of data communication with the control means is provided, and the control means has the turbidity of the hot water water of a predetermined value or more and the predetermined value. When the sterilization apparatus is not operated even when the scheduled start time of sterilization is reached, the remote controller and / or the communication terminal is used to notify the fact.

According to such a configuration, when the turbidity of the hot water in the bathtub is high and the sterilizer is not operated, the user can appropriately detect that fact.

The bath device provided by the second aspect of the present invention includes a hot water distribution section through which hot water in a bathtub can flow in and out, and a disinfectant lamp capable of irradiating hot water in the hot water distribution section with light for disinfection. A bath device including a sterilizing device having a sterilizing device and a control means for executing control of operating the sterilizing device at a predetermined scheduled start time of sterilization, and a bath agent is added to the hot water of the bathtub. In this case, the control means is further provided with an operation switch for making the control means recognize that fact, and the control means puts the bath salt into the hot water of the bathtub by operating the operation switch. When it is recognized that the sterilization has been performed, the sterilization apparatus is configured not to operate even when the predetermined sterilization start scheduled time has arrived.

According to such a configuration, when the bath salt is added to the hot water of the bathtub and the turbidity of the hot water of the bathtub becomes considerably high, the user operates the operation switch so that the sterilizing device is not operated wastefully. It is possible to obtain the same effect as described for the bath device provided by the first aspect of the present invention.

Other features and advantages of the present invention will become more apparent from the following description of embodiments of the invention with reference to the accompanying drawings.

It is explanatory drawing which shows an example of the bath apparatus which concerns on this invention. It is sectional drawing of the main part which shows the sterilization apparatus used in the bath apparatus shown in FIG. It is a flowchart which shows an example of the sterilization processing operation executed in the bath apparatus shown in FIG. It is a flowchart which shows another example of the sterilization processing operation performed in the bath apparatus shown in FIG.

Hereinafter, preferred embodiments of the present invention will be specifically described with reference to the drawings.

The bath device A shown in FIG. 1 is connected to the bathtub 1 via the bathtub 1 installed in the bathroom BR, the hot water circulation path 5 connected to the bathtub 1, and the external pipes 5a and 5b constituting the hot water circulation path 5. It includes a connected hot water supply device WH, a circulation pump P1 provided in the middle of the hot water circulation path 5, a sterilization device E, and a control unit 7 for executing operation control of the hot water supply device WH. In the figure, reference numeral 90 is an outer case of the hot water supply device WH.

The hot water supply device WH is, for example, an instantaneous gas hot water supply device, and has a hot water filling function for the bathtub 1, a bath reheating function, and a general hot water supply function for the hot water tap 60 and the like. In addition, the sterilization treatment operation of hot water in the bathtub 1 can be performed by using the sterilization device E.

Specifically, in the hot water supply device WH, in the general hot water supply, the hot water flowing into the water inlet 2 from the water inlet 20 is sent to the heat exchanger 30 and heated by the burner 31, and the heated hot water is the general hot water supply. This is performed in a manner in which the hot water outlet 6 is circulated and supplied to the hot water tap 60.
In the hot water filling operation to the bathtub 1, the on-off valve V1 provided in the hot water supply channel 50 for bath water is opened, so that the hot water heated by the heat exchanger 30 is circulated from the hot water supply channel 50 for bath water supply. It is carried out in a manner of flowing into the road 5. The hot water circulation path 5 has a configuration in which the internal pipes 5c and 5d of the hot water supply device WH and the heat exchanger 33 for reheating the bath are connected to the external pipes 5a and 5b connected to the adapter 10 of the bathtub 1.
The bath reheating operation is performed in such a manner that the circulation pump P1 is driven on, the hot water of the bathtub 1 is sent to the heat exchanger 33 via the hot water circulation path 5, heated by the burner 34, and then returned to the bathtub 1. Is done.
A water pressure sensor Sa is provided in the hot water circulation path 5, and the water level of the bathtub 1 can be inspected by the water pressure sensor Sa, and a state in which a person has taken a bath (a state in which the body is submerged in the hot water of the bathtub 1) is detected. It is possible to do.

As shown in FIG. 2, the sterilization device E has a hot water inlet 41 and an outflow port 42, a housing 4 whose inside is formed as a hot water flow section 40, and a sterilization lamp housed in the housing 4. 8. Two substantially cylindrical protective covers 81 and 82 covering the disinfectant lamp 8, caps 43a and 43b for closing the upper and lower openings of the housing 4, and a light receiving element 83 are provided. The inflow port 41 and the outflow port 42 of the housing 4 are connected to an intermediate portion of the internal pipe 5c of the hot water circulation path 5.

The disinfectant lamp 8 is, for example, an ultraviolet lamp. Both the protective covers 81 and 82 have translucency against ultraviolet rays emitted from the sterilizing lamp 8, and the hot water of the hot water distribution unit 40 can be sterilized by driving the sterilizing lamp 8 on. .. One of the protective covers 81 is a waterproof member that prevents the disinfectant lamp 8 from coming into contact with hot water in the housing 4, and is made of glass, for example. On the other hand, the other protective cover 82 is made of resin, and in the unlikely event that the protective cover 81 made of glass is damaged, it plays a role of preventing the fragments from being scattered and flowing out to the hot water circulation path 5. In the sterilization treatment of hot water in the bathtub 1, both the sterilization lamp 8 and the circulation pump P1 are driven on, and the hot water in the bathtub 1 is discharged to the hot water circulation path 5 and sent to the hot water distribution section 40 of the sterilization device E. The hot water is sterilized by the above method, and the hot water after the sterilization is returned to the bathtub 1.

The combination of the disinfectant lamp 8 and the light receiving element 83 corresponds to an example of the turbidity detecting means in the present invention. The light receiving element 83 is arranged above the disinfectant lamp 8 inside the protective covers 81 and 82 in a state of being mounted on an appropriate substrate (not shown), and among the ultraviolet rays emitted from the disinfectant lamp 8. The hot water flowing through the hot water distribution unit 40 is set to receive a part of the ultraviolet rays reflected by the inner surface of the housing 4 and then transmitted through the hot water again. It is considered that other light, for example, direct light from the disinfectant lamp 8 does not enter the light receiving element 83 (reference numeral 80 is sockets at both ends of the disinfectant lamp 8 and is non-transmissive). .. The light receiving element 83 can output a signal at a level corresponding to the amount of received ultraviolet rays (illuminance) described above, and when this signal is transmitted to the control unit 7, the control unit 7 will be described later. It is possible to determine the turbidity Ra, Rb, etc. of hot water.

The control unit 7 is configured by using a microcomputer, and corresponds to switch operations of the bathroom BR and the remote controllers 7A and 7B of the kitchen connected to the control unit 7 by communication, and controls the operation of each part of the water heater WH. Perform data processing. The remote controllers 7A and 7B are provided with a plurality of operation switches 72 and a display unit 73 capable of displaying an image, and the remote controller 7A of the bathroom BR can detect that fact when a person enters the bathroom BR. A human body detection sensor Sb is also provided. The human body detection sensor Sb may be configured to be provided at another location in the bathroom BR in place of or in addition to the remote controller 7A.

By operating the operation switch 72, it is possible to reserve and set the scheduled start time of sterilization of hot water in the bathtub 1. However, the control unit 7 does not execute the sterilization treatment when the turbidity of the hot water in the bathtub 1 is equal to or higher than a predetermined value, as will be described later, even when the scheduled start time of sterilization has arrived. It is configured.

Next, the operation of the bath device A described above will be described. At the same time, an example of the operation processing procedure in the bath device A will be described with reference to the flowchart shown in FIG.

First, when the hot water filling operation is performed by performing a switch operation to perform the hot water filling operation on the bathtub 1 and the hot water filling operation is completed, at a predetermined first time T1 after the completion, The sterilization lamp 8 is driven on, and the first turbidity correspondence value detection process for the hot water in the bathtub 1 is started (S1: YES, S2: YES, S3).

In this first turbidity-corresponding value detection process, the ultraviolet rays emitted from the disinfectant lamp 8 and transmitted through the hot water of the hot water distribution unit 40 are received by the light receiving element 83, and the signal output from the light receiving element 83 is received. Based on this, the detection illuminance E1 is determined by the control unit 7, and this detection illuminance E1 is stored as a reference value. Along with this, the disinfectant lamp 8 is driven off (S4: YES, S5).

The detected illuminance E1 is a numerical value corresponding to the transmittance of the ultraviolet rays of the hot water, and does not correspond to the turbidity of the hot water itself. However, the lower the detected illuminance E1, the higher the turbidity of the hot water. Corresponds to one of the values corresponding to. If the timing is immediately after the bathtub 1 is filled with hot water, the bath salt is not added and the bathtub is not bathed, and the hot water in the bathtub 1 is considered to be almost clean water. Therefore, the detection illuminance E1 However, it is used as a reference value to be compared with other detection illuminances E2 and E3 described later.
The first period T1 described above is preferably a short period from the completion of filling the bathtub 1 with hot water so that the bath salt is not added before the determination process of the detection illuminance E1 is performed. If possible, the detection process of the detection illuminance E1 may be performed before the completion of the hot water filling operation in the bathtub 1.

Next, when a person enters the bathroom BR and this is detected by using the human body detection sensor Sb, the circulation pump P1 is operated for a predetermined time and sterilized at a predetermined second time T2 thereafter. The light 8 is driven on, and the second turbidity-corresponding value detection process for the hot water in the bathtub 1 is performed (S6: YES, S7, S8).

In this second turbidity correspondence value detection process, the value of the detection illuminance E2 in the light receiving element 83 is stored in the control unit 7 as a comparison value with the detection illuminance E1, and the sterilization lamp 8 is driven off accordingly. Is done (S9). The second period T2 is set to an appropriate period from, for example, a few minutes after a person enters the bathroom BR, but the second period T2 is started after waiting for the person to leave the bathroom BR. (If the person who entered the bathroom BR does not leave and starts bathing, the second turbidity correspondence value detection process may not be executed).

When the detected illuminance E2 is obtained as described above, the control unit 7 calculates the illuminance ratio Ra = E2 / E1 at that time (S10). The higher the turbidity of the hot water, the smaller the illuminance ratio Ra. In the relationship between the illuminance ratio Ra and the predetermined first threshold value TH1, when Ra ≧ TH1 is not established, the turbidity of the hot water is equal to or higher than the predetermined value because a bath agent is added to the hot water. As a result, it is determined that the sterilization operation is not performed (S11: NO, S23).

Further, the above-mentioned fact is notified by using the remote controllers 7A and 7B. This notification can be performed by displaying a specific image or character on the display unit 73, lighting or blinking a predetermined lamp (not shown), or generating a voice message. As a result, the user can appropriately detect that the sterilization operation is not performed, and it is possible to prevent the user from feeling distrust that the sterilization operation is not performed. When the bath device A can be connected to the wide area communication network, the data is transmitted to a predetermined communication terminal such as a smartphone or a mobile phone owned by the user to notify the above. It may be.

If a bath agent is added to the hot water of the bathtub 1 when a person enters the bathroom BR described above, the hot water becomes so turbid that Ra ≧ TH1 does not hold, but according to the above-mentioned treatment, that fact. It is possible to judge appropriately. When such a determination is made, the sterilization treatment is not executed even if the predetermined sterilization start time comes after that (S24: YES, S25).

When the bath agent is put into the hot water of the bathtub 1, the turbidity is high, and the illuminance ratio Ra is small, the ultraviolet rays emitted from the sterilizing lamp 8 do not act efficiently on the hot water, and the sterilizing effect is almost obtained. However, if the sterilization process is not executed in such a case, the waste of power consumed in the sterilization process can be eliminated. Further, it is not preferable to operate the circulation pump P1 with the bath salt charged in the hot water because the service life of the circulation pump P1 is shortened, but such a problem can be appropriately avoided. ..

On the other hand, unlike the above, when the turbidity of the hot water is low and Ra ≧ TH1 is established, it is not determined that the above-mentioned sterilization operation is not performed. In this case, after that, when it is detected that a person has bathed in the bathtub 1 based on the change in water pressure (change in water level) detected by the water pressure sensor Sa, a predetermined third period thereafter. The circulation pump P1 is operated by T3 for a predetermined time, the sterilization lamp 8 is driven on, and the third turbidity correspondence value detection process for the hot water in the bathtub 1 is performed (S11: YES, S12: YES, S13, S14).

In this third turbidity correspondence value detection process, the value of the detection illuminance E3 in the light receiving element 83 is stored in the control unit 7 as a comparison value with the detection illuminance E1, and the sterilization lamp 8 is driven off accordingly. (S15). The third period T3 is set to an appropriate period, for example, from a few minutes after the start of bathing, but the third period T3 is started after waiting for the bather to leave the bathroom BR. You may do it.

When the detected illuminance E3 is obtained as described above, the control unit 7 calculates the illuminance ratio Rb = E3 / E1 at that time (S16). The smaller the illuminance ratio Rb, the higher the turbidity of the hot water. When Rb ≧ TH1 is not established in the relationship between the illuminance ratio Rb and the predetermined first threshold value TH1, the turbidity of the hot water is equal to or higher than the predetermined value as in the case where Ra ≧ TH1 in step S11 described above is not established. As a result, it is decided not to perform the sterilization operation, and further, a notification to that effect is given (S17: NO, S23). A bath agent may be added to the hot water of the bathtub 1 by the bather, but even in such a case, if the turbidity of the hot water becomes more than a predetermined value due to the addition of the bath agent, it is appropriately determined to that effect. , It is possible to prevent unnecessary sterilization treatment from being executed after that.

Unlike the above, when the turbidity of the hot water is low and the relationship of Rb ≧ TH1 is established, the control unit 7 determines that the bath salt is not used and decides to perform the sterilization operation as scheduled. It is done (S17: YES, S18). Therefore, when a predetermined scheduled start time for sterilization arrives thereafter (S19: YES), the sterilization process is started at that time.

However, in this sterilization treatment, preferably, the illuminance ratio Rb is compared with the second threshold value TH2 (a value larger than the first threshold value TH1), the turbidity of hot water is higher, and the relationship of Rb ≧ TH2 is established. If this is not the case, a sterilization treatment with a higher degree of sterilization is executed (S20: NO, S22). On the other hand, when the turbidity of the hot water is low and the relationship of Rb ≧ TH2 is established, the sterilization treatment with a low degree of sterilization is executed (S20: YES, S21). According to such a treatment, depending on the turbidity of the hot water, the necessary and sufficient sterilization treatment for sanitizing the hot water can be appropriately performed without waste or with less waste.
In order to make a difference between high and low in the degree of sterilization treatment, the luminescence of the sterilization lamp 8, the sterilization treatment time, and the operating speed of the circulation pump P1 (the flow velocity of hot water in the hot water distribution unit 40). A specific example is a means for making at least one of them different.

In the bath device A, in addition to or in place of the series of operations described above, an operation processing procedure as shown in the flowchart of FIG. 4 may be possible. This will be described below.

First, as a precondition for executing the operation processing procedure of FIG. 4, in the remote controllers 7A and 7B of the bath device A, the user operates the operation switch 72 when the bath salt is added to the hot water of the bathtub 1. By doing so, it is possible to set that fact and have the control unit 7 recognize it.

In the operation processing procedure shown in FIG. 4, when a predetermined sterilization start scheduled time has arrived, the control unit 7 determines in advance by switch operation that the bath salt has been added to the hot water of the bathtub 1. (S31: YES, S32). Here, if the above is preset, the sterilization process is not executed (S32: YES, S33). On the other hand, if the above is not set in advance, the sterilization process is executed as scheduled (S32: NO, S34).

According to such an operation treatment procedure, when the bath salt is put into the hot water of the bathtub 1 and the turbidity of the hot water is considerably high, it is appropriate that the sterilization treatment having almost no sterilization effect is wastefully executed. It is possible to avoid it. Although it is necessary for the user to input and set the fact that the bath salt has been added to the hot water of the bathtub 1 by operating a switch, if this input setting is made, the sterilization process can be surely not executed. , It is also possible to give the user a sense of security.

The present invention is not limited to the contents of the above-described embodiments. The specific configuration of each part of the bath device according to the present invention can be variously redesigned within the scope intended by the present invention.

In the above-described embodiment, as a method for determining whether or not the turbidity of the hot water in the bathtub 1 is equal to or higher than a predetermined value, the predetermined illuminance ratios Ra = E2 / E1 and Rb = E3 / E1 are the first and second methods. Although compared with the thresholds TH1 and TH2, the present invention is not limited to this. As described above, the definition of "turbidity" in the present invention is the degree of turbidity, and for example, the translucency, absorbance, reflectance, similar values, or other values of hot water are used. Therefore, it is possible to determine whether or not the turbidity of the hot water is equal to or higher than a predetermined value.

The scheduled start time of sterilization is not limited to the timer setting, and for example, the timing when the bather leaves the bathroom can be set as the scheduled start time of sterilization.
In the operation processing procedure shown in FIG. 3, the degree of sterilization when performing the sterilization treatment of hot water is divided into two stages of low and high in steps S21 and S22, but the number of stages is more than that. You can also do it.

The sterilization device can have a configuration different from that of the sterilization device E shown in FIG. 2, and for example, the protective cover 82 may be omitted. Further, as the housing of the sterilizer, a tubular housing in which the entire or part of the peripheral wall portion is made of a translucent material is used, and the inside of this housing is used as a hot water flow portion and is removed to the outside of this housing. By arranging the fungus lamp, it is possible to irradiate the hot water in the housing with light for sterilization from the outside of the housing.
