Description

Massager {MASSAGE MACHINE}

The present invention relates to a massage machine having a massage device and a heat source in the backrest.

Conventionally, for example, a chair type massager is provided in the backrest part, and is provided with the massage mechanism which has a massage ball. The chair-type massager performs a predetermined motion on the massage ball while the massage ball is in contact with the acupuncture points and the meridians of the back, and promotes blood circulation of the shoulder or back, thereby relieving stiffness of the shoulder or back. Such chair type massagers have been proposed in the related art, and are widely used in general homes and public facilities.

In recent years, a massage device equipped with an ottoman (for example, Patent Document 1) having a heat source that heats a user's body and a heat source are provided in the backrest portion to sample the massage device (massage ball). Massager configured to operate integrally with the heat source has been developed.

Prior art literature

Patent Document 1: Japanese Unexamined Patent Publication No. 2006-051062

However, in the massager having a heat source operating integrally with the sampler as described above, the entire backrest portion or part of the backrest portion is covered by the cover portion so that the sampler of the massage mechanism does not directly contact the user's body. That is, heat from the heat source is transmitted to the user through the cover portion. For this reason, since temperature control of a heat source is performed by measuring the temperature of a heat source using temperature sensors, such as a thermistor, for example, a massager could not set the surface temperature of a cover part to desired temperature.

In addition, since the heat source operates integrally with the sample, when the position of the sampler does not change or the amount of change in the position of the sampler is small, heat from the heat source is concentrated in a certain range (part) of the user's body. Accordingly, a problem arises in that it becomes difficult to warm a part of the body so as to obtain an effect of an appropriate thermal sample, and this problem is hoped to be improved.

An object of the present invention is to provide a massaging machine capable of more appropriately performing a heat sample to be carried out using a heat source operating integrally with a sample.

In order to solve the above-mentioned problems, the invention described in claim 1 is a massage device which is accommodated inside the back support part and has a sampler in a seat provided at a user's seat and a back seat provided at the rear of the seat. The backrest includes a heat source accommodated in the inside of the part to provide heat to the back of the user, and a cover part provided to cover at least the movable range of the sampler on the front surface of the backrest part so that the sampler does not directly contact the user. And a control unit for controlling the massage device and the heat source to massage the user, wherein the heat source is provided to be operated integrally with the sample, and the control unit is provided with an operating state of the heat source and The surface temperature of the cover part is based on the operating state of the sampler. In addition, when the surface temperature of the inferred cover portion is higher than a set temperature, the operating state of at least one of the heat source and the sampler is changed.

In the present invention, the heat source is provided to be able to operate integrally with the sample. The control unit infers the surface temperature of the cover part based on the operation state of the heat source and the operation state of the sampler. The control unit changes the operating state of at least one of the heat source and the sampler when the surface temperature of the cover portion is higher than the set temperature. Here, the "operation state of the heat source" refers to either the driving state or the stop state of the heat source, and the "operation state of the sampler" refers to the position of the sampler or the sample pattern (operation trajectory of the sampler), or the number of samples. As used herein, the following meanings are used. As described above, when the control unit infers the surface temperature of the cover unit based on the operating state of the heat source and the operation state of the sampler, and the surface temperature of the cover unit is higher than the set temperature which is appropriate for the user, the control unit may be a heat source and By changing at least one operating state of the sampler, the massaging machine can lower the surface temperature of the portion of the cover portion to an appropriate temperature. Accordingly, the massaging machine can perform a more appropriate heat sample for the user.

The invention according to claim 6, wherein the backrest provided at the back of the seat and the back of the seat, in which the user is seated, the backrest is accommodated in the backrest and has a sampler, and is housed in the backrest. Massage to the user and the backrest including a heat source for providing heat to the back of the cover and a cover portion provided to cover at least the movable range of the sampler on the front of the backrest portion so that the sampler does not directly contact the user. And a control unit for controlling the massage device and the heat source to implement the heat source, and the heat source is provided to be able to operate integrally with the sample, and the backrest unit performs expansion and contraction motion along the front and rear directions of the massage device. Including an airbag to perform an air massage to the user. The control unit infers the surface temperature of the cover part according to the operating state of the heat source and the operation state of the sampler. When the surface temperature of the inferred cover part is higher than a set temperature, the control unit inflates and operates the air bag. It is characterized by extending the distance from the user's body.

In the present invention, the heat source and the backrest, which can be operated integrally with the sample, are provided with an airbag for performing air massage to the user by performing the expansion and contraction motion in the front-back direction of the backrest portion. The control unit infers the surface temperature of the cover unit based on the operating state of the heat source and the operating state of the sampler. When the surface temperature of the inferred cover portion is higher than the set temperature, the controller expands the airbag to expand the distance between the heat source and the user's body. Thus, since the body of the user is separated from the heat source by the airbag when the surface temperature of the inferred cover portion is higher than the set temperature which is an appropriate temperature, the massager is suitable for suppressing excessive warming of the user's body part (part). Thermal samples can be performed.

Moreover, the massage mechanism 20 is equipped with the strong (front and back) drive part 52 (strong drive motor 52a), and the width drive part 53 (width drive motor 53a). By operating the driving units 51 to 53 in cooperation, the specimen 21 operates in two or three dimensions. The sample ruler 21 abuts against the inner surface of the cover portion 13b while the sample ruler 21 protrudes forward. Accordingly, the sampler 21 may perform massage, such as a kneading operation or a tapping operation, on the sample part such as the shoulder, the back, or the waist of the user through the cover part 13b.

As shown in FIG. 6, the up-and-down drive part 51, the strong (front and rear) drive part 52, and the width drive part 53 are provided with drive motors 51a-53a as a drive source, respectively, and each drive motor 51a- The driving of 53a) is controlled by the controller 61. In more detail, the detection part from the up-and-down sensor 55, the intensity | strength sensor 56, and the width sensor 57 with which each part of the massage mechanism 20 is input is input to the control part 61. The control unit 61, based on the detection signal of each of the sensors 55 to 57, the massage mechanism 20 (the respective driving units 51 to 53) including the state (position and posture) of the sampler 21. Detects the state of.

As shown in FIG. 2, the pair of samplers 21 of the massage device 20 includes a pair of arms 22 (only a single arm 22 is shown) and a heater unit provided in each arm 22 ( 23, a massage ball 24 connected to the heater unit 23, and a fixing member 25 for sandwiching and supporting the massage ball 24 with the heater unit 23. On the other hand, the fixing member 25 is formed of aluminum having high thermal conductivity.

As shown in FIGS. 3 and 4, each heater unit 23 is configured to support a PTC (Positive Temperature Coefficient) heater 30 by being sandwiched between the first case member 31 and the second case member 32. . Each heater unit 23 is provided inside the width direction of the pair of arms 22, respectively. On the other hand, each case member 31 and 32 accommodating each PTC heater 30 employs aluminum as a material having high thermal conductivity and high rigidity.

The first case member 31 in the width direction outer side is fixed by adopting screws 33a and 33b to the arm 22. 3 and 4, the inner surface on the inner side in the width direction of the first case member 31 has the abutting portion 31a at the position corresponding to the PTC heater 30 protruding inward in the width direction . 6, each PTC heater 30 is electrically connected with the control part 61, and the control part 61 determines the power supply to each PTC heater 30. As shown in FIG.

The second case member 32 includes, for example, a rubber pad 41 made of a silicon-based material having high thermal conductivity and high elasticity at a position corresponding to the PTC heater 30 on the inner surface outside the width direction. . As shown in FIG. 4, the PTC heater 30 is sandwiched and supported between the contact portion 31a of the first case member 31 and the rubber pad 41 of the second case member 32. The rubber pad 41 is configured to elastically deform in accordance with the pressure on the PTC heater 30 when the rubber pad 41 and the PTC heater 30 are sandwiched and supported using the abutting portion 31a. do. That is, in the PTC heater 30, the PTC heater 30 is press-contacted to the second case member 32, and efficiently transmits heat to the second case member 32 side of the heater unit 23. It is possible to.

The contact portion 32a of the second case member 32 has a curved shape protruding toward the user side and abuts against the user's body through the cover portion 13b. Moreover, the contact part 32a is formed so that it may extend toward the outer side in the width direction to about thickness (length in the width direction) of the 1st case member 31. FIG. For this reason, by condensing the heat of the PTC heater 30 to the 2nd case member 32 side of the heater unit 23, the spread of the heat other than the contact part 32a is suppressed actively. In addition, it is preferable that portions other than the contact portions 32a of the first case member 31 and the second case member 32 have a shape that follows the shape of the PTC heater 30 as much as possible.

In addition, the thermistor 42 is fixed to the inner side in the width direction of the second case member 32 with the screw 32b. As shown in FIG. 7, the thermistor 42 is electrically connected to the control unit 61. Accordingly, the heat of the PTC heater 30 is transmitted to the second case member 32, which is the outer shell of the heater unit 23, and the thermistor 42 can monitor the temperature of the heat of the PTC heater 30. have.

The extension part 32c which protrudes toward the inner side in the width direction is formed in the 2nd case member 32. As shown in FIG. An engaging projection 32d having an almost square shape is formed at the tip of the extension portion 32c in the extension direction. The cylindrical portion 25a of the fixing member 25 having a substantially cylindrical shape is fitted to the extension portion 32c of the second case member 32 to the outside. In order to prevent the fixing member 25 from falling out of the screw hole 32e, the screw 46 is fitted into the screw hole 32e formed in the extension part 32c.

An engagement hole 25c having a substantially rectangular shape is formed on the axial end side of the inner surface of the cylindrical portion 25a. The engagement hole 25c of the cylindrical part 25a engages the extension part 32c which protrudes toward the inner side in the width direction from the outer surface of the 2nd case member 32, in order to prevent the fixing member 25 from rotating. It is engaged with the projection part 32d.

In addition, a massage ball 24 is provided on the outer circumferential surface of the cylindrical portion 25a of the fixing member 25 so as to be rotatable using two bearings 24a and 24b. On the axial end side of the cylindrical portion 25a, a wide diameter portion 25b having an outer diameter larger than the outer diameter of the cylindrical portion 25a is formed to protrude toward the width direction inner side than the massage ball 24. According to this structure, the massage ball 24 is prevented from falling out in the width direction (axial direction) by the wide diameter portion 25b. In addition, the massage ball 24 is slightly smaller than the distance from the axis center of the extension part 32c of the second case member 32 to the abutting portion 32a of the second case member 32 (eg, 3 Mm) has a large radius. Accordingly, when the massage ball 24 comes into contact with the user's body through the cover portion 13b, the massage ball 24 is deformed by the contact pressure of the user's body, and is formed of a rigid body. The abutting portion 32a of the two case members 32 is in light contact with the user as much as possible so that only heat is appropriately transmitted to the user.

In the massager 10 having the above-described configuration, electric power is supplied to the PTC heater 30 through the control unit 61 from an external power source not shown. The control part 61 monitors the temperature of the PTC heater 30 (2nd case member 32), and controls the temperature of PTC heater 30 to about 55 degreeC, for example.

Moreover, the control part 61 changes the surface temperature of the cover part 13b heated by the PTC heater 30 (the 2nd case member 32), and the operation state of the PTC heater 30 and the sampler 21. It can be inferred based on the time when the operation state of the PTC heater 30 and the sampler 21 does not change. In detail, as shown in FIG. 5A, FIG. 5B, and FIG. 7, the control part 61 is a drive (on) state of the PTC heater 30, and the sample position of the up-down direction of the sampler 21 is the upper side, the width | variety. When the massage device 20 is operated for a predetermined time (T1) with a certain operation pattern (for example, kneading operation) under the condition that the sample position in the direction is the outer side and the sample position in the strong and weak direction is the river side (front side). The controller 61 switches the driving of the PTC heater 30 from the on state to the stopped (off) state. This is because, when the operation state of the PTC heater 30 is the driving (on) state, when the operation (position) of the sampler 21 does not change for a predetermined time T1, the control unit 61 controls the cover unit 13b. It is judged that the surface temperature of) exceeds the upper limit temperature A which is an appropriate setting temperature, and switches the operation state of the PTC heater 30 from a drive state to a stop state. That is, when the position of the sampler 21 does not change and the massage device 10 operates for a predetermined time T1 in a constant operation pattern, the surface temperature of the cover part 13b becomes too high, and the heat of the PTC heater 30 is increased. It is focused on the body part of the user. By changing the operating state of the PTC heater 30 from a driving state to a stationary state, the massage device 10 lowers the temperature of the PTC heater 30, and a more suitable thermal sample is implement | achieved.

After the predetermined time T1 has elapsed, the control unit 61 makes the PTC heater 30 stop until the predetermined time T2 elapses, and then the operating state of the PTC heater 30 is stopped in the stopped state. The operation is switched to the drive state, and then the above-described operation is repeated.

The characteristic operational effects of the present embodiment are described below.

(1) When the PTC heater 30 is in the driving state and at the same time the operating state of the sampler 21 does not change for a predetermined time, the control unit 61 covers the cover portion 13b rather than the upper limit temperature A which is the set temperature. Infer whether the surface temperature is high. When the control part 61 infers that the surface temperature of the cover part 13b is higher than the upper limit temperature A, the control part 61 switches the operation state of the PTC heater 30 from a drive state to a stop state. Thus, the massage device 10 is based on the time (predetermined time T1) in which the operation state of the sampler 21 and the operation state of the PTC heater 30 continue while the PTC heater 30 is driving. By inferring the surface temperature of the cover portion 13b, the surface temperature of the cover portion 13b can be lowered to an appropriate temperature. Accordingly, the massage device 10 can implement a more appropriate heat sample for the user.

(2) When the PTC heater 30 is being driven and the operation state of the sampler 21 does not change for a predetermined time, the controller 61 indicates that the surface temperature of the cover portion 13b is higher than the upper limit temperature A. FIG. Infer. When the controller 61 infers that the surface temperature of the cover portion 13b is higher than the upper limit temperature A, the controller 61 changes the operation state of at least one of the PTC heater 30 and the sampler 21. . In this way, the massage device 10 uses the surface temperature of the cover portion 13b based on the time of maintaining the operation state of the sample heater 21 and the operation state of the PTC heater 30 while the PTC heater 30 is being driven. By inferring, the surface temperature of the cover portion 13b can be lowered to an appropriate temperature. Accordingly, the massage device 10 can implement a more appropriate heat sample for the user.

(3) When the surface temperature of the cover part 13b inferred is higher than the upper limit temperature A, the control part 61 stops the drive of the PTC heater 30. FIG. In this way, when the surface temperature of the inferred cover portion 13b is higher than the upper limit temperature A, which is an appropriate temperature, the driving of the PTC heater 30 is stopped, so that the massager 10 has the surface of the cover portion 13b. The temperature can be lowered to an appropriate temperature. Accordingly, the massage device 10 can implement a more appropriate heat sample for the user.

(4) When the surface temperature of the cover part 13b inferred is higher than the upper limit temperature A, the control part 61 drives the sampler 21, and changes the position of the sampler 21. FIG. In this way, when the surface temperature of the inferred cover portion 13b is higher than the upper limit temperature A, which is an appropriate temperature, the position of the sampler 21 is changed, so that the massaging machine 10 is part (part) of the user's body. Appropriate thermal samples can be carried out to suppress the excessive warming.

(5) The backrest portion 13 is provided with an airbag 70 for giving an air massage to the user by the expansion and contraction motion of the backrest portion 13 in the front-rear direction. When the surface temperature of the cover part 13b inferred is higher than the upper limit temperature A, the control part 61 expands and operates the airbag 70, and widens the space | interval of the PTC heater 30 and a user's body. In this way, when the surface temperature of the inferred cover portion 13b is higher than the upper limit temperature A, which is an appropriate temperature, the user's body is separated from the PTC heater 30 by the airbag 70, so that the massaging machine 10 Can perform an appropriate thermal sample that suppresses excessive warming of a part (part) of the user's body.

In addition, you may change embodiment of this invention as follows.

In the above-described embodiment, when the operation state of the massage ball 24 (sample 21) is not changed in a driving time (on) state of the PTC heater 30, the PTC is changed. The driving of the heater 30 has been stopped (off), but is not limited thereto.

For example, as shown in FIG. 8, when the operation state of the massage ball 24 (sample 21) does not change for the predetermined time T1 in the driving state of the PTC heater 30, a sample is required. The structure which changes the position of the ruler 21 may be employ | adopted. In this case, since the massager 10 does not stop driving of the PTC heater 30, it is possible to immediately apply a heated sample to another body part of the user after the position change of the sampler 21.

In the case where the operation state of massage ball 24 (specimen 21) is not changed for the predetermined time T1 in the driving state of PTC heater 30, for example, A configuration for changing the operation pattern may be employed. More specifically, the massage device 10 is, for example, in contact with the kneading operation with a relatively long contact time for the user's body (cover portion 13b) to contact the sampler 21 (massage ball 24). The surface temperature of the cover portion 13b can be lowered by using a configuration in which the time is changed to a relatively short tapping operation.

In addition to the above-described configuration, for example, an air bag 70 (shown in broken lines in FIG. 1) capable of inflating and contracting along the front-back direction may be provided in the backrest portion 13 of the massager 10. In this case, as shown in FIG. 9, when the operation state of the massage ball 24 (sample 21) does not change for a predetermined time T1 in the driving state of the PTC heater 30, the control part 61 and The air pump 71 inflates the airbag 70 and may separate the user's body (cover portion 13b) from the PTC heater 30. In such a configuration, since the driving of the PTC heater 30 is not stopped, the massager 10 can immediately apply a heated sample to other body parts of the user after the position change of the sampler 21. In addition, by providing the airbag 70, the massager 10 can perform the air massage using the airbag (70). In addition, you may change suitably the airbag 70 to arbitrary positions of the backrest part 13. As shown in FIG.

In the above-mentioned embodiment, although the thermistor 42 which measures the temperature of the PTC heater 30 (2nd case member 32) is provided in the 2nd case member 32, it is not limited to this, The thermistor ( 42 may be omitted. In this case, the temperature of the PTC heater 30 may be inferred, for example, by obtaining the temperature change of the PTC heater 30 beforehand by experiment.

In the above-described embodiment, the ottoman 14 is provided, but the ottoman 14 may be omitted.
