The controller 61 switches the operation state of the PTC heater 30 from the driving state to the stop state when it is estimated that the surface temperature of the cover portion 13b is higher than the upper limit temperature A.

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 a backrest, and has a massage device having a massage ball. The chair-type massager performs a predetermined operation on the massage ball in a state in which the massage ball is in contact with the back acupuncture points and meridians, thereby promoting blood circulation in the shoulders and back, thereby resolving stiffness of the shoulders and back. Such a chair type massage machine has been proposed in the past, and it has been widely used in general households and public facilities.

In recent years, a massager having an ottoman having a heat source for imparting heat to a user's body (see, for example, Patent Document 1) and a heat source are provided on the backrest, A massager configured to operate as a single heat source has been developed.

Patent Document 1: JP-A-2006-051062

However, as described above, in the massage machine provided with the heat source that operates integrally with the sample holder, the entire backrest portion or the backrest portion is covered by the cover portion so that the sample of the massage device does not directly contact the user's body. That is, the heat from the heat source is transmitted to the user through the cover portion. Because of this, the temperature of the heat source is measured by using a temperature sensor such as a thermistor, for example, so that the massager can not set the surface temperature of the cover part at a desired temperature.

Further, since the heat source operates integrally with the sample, heat from the heat source is concentrated on a certain range (part of the user's body) when the position of the sample does not change or the amount of change in the position of the sample is small. Accordingly, there arises a problem that it becomes difficult to obtain a proper effect of a warm sample by making a part of the body warm, and it is hoped that such a problem will be improved.

SUMMARY OF THE INVENTION An object of the present invention is to provide a massage machine which can more suitably perform a warm sample using a heat source that operates in unison with a sample holder.

In order to solve the above-mentioned problems, the invention described in claim 1 is characterized in that a backrest provided on a seat portion in which a user is seated and a rear portion of the seat portion includes a massage device accommodated in the backrest portion and having a sample holder, And a cover portion provided to cover at least the movable range of the specimen on the front surface of the backrest portion so that the specimen does not directly contact the user, the heat source accommodated in the back portion of the backrest, And a control unit for controlling the massage device and the heat source to massage the user, wherein the heat source is provided so as to be able to operate integrally with the sample person, and the control unit controls the operation state of the heat source, And the surface temperature of the cover portion And the operating state of at least one of the heat source and the specimen is changed when the temperature of the surface of the cover part is lower than the set temperature.

In the present invention, the heat source is provided so as to be able to operate integrally with the sample holder. The controller estimates the surface temperature of the cover part based on the operation state of the heat source and the operation state of the specimen person. The control unit changes the operation state of at least one of the heat source and the specimen when the surface temperature of the cover unit is higher than the set temperature. Here, the "operating state of the heat source" refers to either a state in which the heat source is in the driving state or a stationary state, and the term "operating state of the specimen" means the position of the specimen or the specimen pattern (operation locus of the specimen) And the same meaning is used in the following. In this way, if the control unit inferences the surface temperature of the cover unit based on the operation state of the heat source and the specimen person, and if the surface temperature of the cover unit is higher than the set temperature, which is an appropriate temperature for the user, By changing the operating state of at least one of the sample person, the massager can lower the surface temperature of that part of the cover part to an appropriate temperature. Accordingly, the massager can perform a more suitable thermal sample for the user.

The invention according to claim 6 is a backrest provided in a seat portion in which a user is seated and a rear portion of the seat portion, wherein the backrest portion is housed in the backrest portion and is accommodated inside the backrest portion, And a cover portion provided to cover at least the movable range of the specimen holder on the front surface of the backrest portion so that the specimen does not directly contact the user, and a massage portion And a control unit for controlling the massage device and the heat source to perform the massage, wherein the heat source is provided so as to be able to operate integrally with the sample person, and the backrest unit performs an expansion and contraction operation along the front- Include an air bag that allows the user to perform an air massage. Wherein the control unit estimates the surface temperature of the cover unit based on the operation state of the heat source and the operation state of the specimen, and when the surface temperature of the cover unit is higher than the set temperature, the airbag is inflated, And the distance between the user and the user is widened.

In the present invention, the heat source and the backrest part, which can operate integrally with the sample holder, are provided with an airbag for performing air massage to the user by performing expansion and contraction operations in the back and forth direction of the backrest part. The controller estimates the surface temperature of the cover part based on the operation state of the heat source and the operation state of the specimen person. The control unit causes the airbag to expand when the surface temperature of the covered cover unit is higher than the set temperature, thereby widening the space between the heat source and the user's body. As described above, when the surface temperature of the covered cover portion is higher than the set temperature, which is an appropriate temperature, since the user's body is separated from the heat source by the airbag, the massage device is suitable for restraining the user from over- A hot sample can be run.

A massager according to an embodiment of the present invention will be described with reference to the drawings.

Fig. 1 shows a schematic configuration of a massage machine according to the present embodiment. As shown in Fig. 1, the leg portion 11 of the massage machine 10 is placed on a floor surface (not shown). On the upper portion of the leg portion 11 of the massage device 10, a seat portion 12 to which a user can sit is fixed. The back portion of the seat portion 12 is provided so that the backrest portion 13 for leaning the user can tilt. An ottoman 14 for raising the legs of the user is provided at the front portion of the seat portion 12 so as to be able to tilt. In addition, an armrest portion 15 for supporting the user's arm is provided on both sides of the backrest portion 13 and across the front portion of the seat portion 12. [

As shown in Figs. 1 and 5A and 5B, the backrest portion 13 includes a backrest main body 13a and a cover portion 13b covering at least the front surface of the backrest main body 13a. In addition, the backrest main body 13a has a main body case 13c having an opening on the front surface and being made of a hard resin material. A guide rail (not shown) is provided along the vertical direction of the backrest portion 13 in the body case 13c. A massage device 20 is attached to the backrest main body 13a so as to be movable up and down along the guide rails.

The massage device 20 operates along the up and down direction by the up and down driving part 51 (up and down driving motor 51a; see Fig. 6) provided in the massage device 20. [ The massaging mechanism 20 also includes a strong (front and rear) driving part 52 (strong driving motor 52a) and a width driving part 53 (width driving motor 53a). As each of the driving units 51 to 53 cooperates and operates, the specimen holder 21 operates in a two-dimensional or three-dimensional manner. The specimen holder 21 comes into contact with the inner surface of the cover portion 13b while rubbing against the inner surface of the cover portion 13b by projecting the specimen holder 21 forward. Accordingly, the specimen holder 21 can massage the specimen parts such as the shoulders, back part, and waist of the user through the cover part 13b.

6, the up and down driving unit 51, the strength (front and rear) driving unit 52 and the width driving unit 53 are provided with driving motors 51a to 53a as driving sources, 53a are controlled by the control unit 61. [ More specifically, the detection signals from the upper and lower sensors 55, the intensity sensor 56, and the width sensor 57 provided in the respective portions of the massage mechanism 20 are input to the control unit 61. The control unit 61 controls the massage device 20 (each of the driving units 51 to 53) including the state (position and posture) of the sample person 21 based on the detection signals of the respective sensors 55 to 57, As shown in FIG.

2, the pair of sample members 21 of the massage device 20 includes a pair of arms 22 (only a single arm 22 is shown), a heater unit (not shown) provided in each arm 22 A massage ball 24 connected to the heater unit 23 and a fixing member 25 for holding the massage ball 24 between the heater unit 23 and the fixing member 25. On the other hand, the fixing member 25 is formed of aluminum having high thermal conductivity.

3 and 4, each of the heater units 23 is configured to support a PTC (Positive Temperature Coefficient) heater 30 between the first case member 31 and the second case member 32 . Each of the heater units 23 is provided inside the pair of arms 22 in the width direction. On the other hand, the case members 31 and 32 that house the respective PTC heaters 30 employ aluminum as a material having high thermal conductivity and high rigidity.

The first case member 31 on the outer side in the width direction is fixed to the arm 22 by using screws 33a and 33b. 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 of the PTC heaters 30 is electrically connected to the control unit 61, and the control unit 61 determines power to be supplied to each of the PTC heaters 30.

The second case member 32 is provided with a rubber pad 41 made of, for example, a silicon-based material having high thermal conductivity and high elasticity at a position corresponding to the PTC heater 30 on the inner surface on the outside in the width direction . 4, the PTC heater 30 is sandwiched between the abutting portion 31a of the first case member 31 and the rubber pad 41 of the second case member 32. As shown in Fig. The rubber pad 41 is elastically deformed in accordance with the pressure against the PTC heater 30 when the PTC heater 30 is supported between the rubber pad 41 and the PTC heater 30 by using the abutting portion 31a do. That is, the PTC heater 30 is in a state in which the PTC heater 30 is in pressure contact with 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 do.

The abutting portion 32a of the second case member 32 has a curved shape protruding toward the user side and contacts the user's body through the cover portion 13b. The abutting portion 32a is formed so as to extend toward the outside in the width direction on the order of the approximate thickness (length in the width direction) of the first case member 31. [ The heat of the PTC heater 30 is concentrated on the side of the second case member 32 of the heater unit 23 so that the diffusion of heat to the area other than the abutting portion 32a is positively suppressed. It is preferable that the portions of the first case member 31 and the second case member 32 other than the abutting portion 32a have shapes conforming to the shape of the PTC heater 30 as much as possible.

A thermistor 42 is fixed to the inside of the second case member 32 in the width direction by screws 32b. As shown in Fig. 7, the thermistor 42 is electrically connected to the control section 61. Fig. 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 second case member 32 is formed with an extended portion 32c projecting inward in the width direction. An engaging protrusion 32d having a substantially rectangular shape is formed at the distal end of the extending portion 32c in the extending direction. The cylindrical portion 25a of the fixing member 25 having a substantially cylindrical shape is fitted to the extended portion 32c of the second case member 32 to the outside. A screw 46 is fitted in the screw hole 32e formed in the extended portion 32c in order to prevent the fixing member 25 from coming off the screw hole 32e.

An engaging hole 25c having a substantially rectangular shape is formed on the axial end side of the inner surface of the cylindrical portion 25a. The engaging hole 25c of the cylindrical portion 25a is engaged with the engagement portion 32c of the extending portion 32c protruding inward in the width direction from the outer surface of the second case member 32 in order to prevent the fixing member 25 from rotating And is engaged with the projecting portion 32d.

The massage ball 24 is rotatably supported on the outer circumferential surface of the cylindrical portion 25a of the fixing member 25 by using two bearings 24a and 24b. A large diameter portion 25b having an outer diameter larger than the outer diameter of the cylindrical portion 25a is formed on the axial end side of the cylindrical portion 25a so as to project toward the inner side in the width direction than the massage pad 24. With this configuration, the massage ball 24 is prevented from falling in the width direction (axial direction) by the wide diameter portion 25b. The massage ball 24 is slightly smaller than the distance from the axial center of the extended portion 32c of the second case member 32 to the abutment portion 32a of the second case member 32 Mm). Thus, 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 against the user's body, The abutting portion 32a of the two case members 32 is lightly contacted to the user as much as possible so that only the heat is properly transmitted to the user.

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

The control section 61 controls the surface temperature of the cover section 13b to be warmed by the PTC heater 30 (second case member 32) to the operating state of the PTC heater 30 and the sample holder 21 It is possible to deduce based on the time during which the operating state of the PTC heater 30 and the specimen holder 21 does not change. 5A and FIG. 5B and FIG. 7, the control unit 61 determines whether the PTC heater 30 is in the ON (ON) state or the sample position in the vertical direction of the sample holder 21 is in the upper When the massage device 20 is operated for a predetermined time T1 in a certain operation pattern (for example, a kneading operation) under the condition that the position of the sample in the direction is the outer side and the sample position in the strong direction is the strong side The control unit 61 switches the driving of the PTC heater 30 from the on state to the stop (off) state. When the operation (position) of the specimen holder 21 does not change for the predetermined time T1 when the operating state of the PTC heater 30 is in the driving (on) state, the controller 61 controls the cover portion 13b ) Exceeds the upper limit temperature (A), which is an appropriate set temperature, and switches the operating state of the PTC heater (30) from the driving state to the stopping state. That is, when the position of the sample holder 21 is not changed and the massage machine 10 operates for a predetermined time (T1) in a constant operation pattern, the surface temperature of the cover portion 13b becomes excessively high and the heat of the PTC heater 30 This focuses on a part of the body of the user. The massage machine 10 lowers the temperature of the PTC heater 30 by switching the operating state of the PTC heater 30 from the driving state to the stopping state to realize a more suitable heating sample.

The control unit 61 sets the PTC heater 30 to the stopped state until the predetermined time T2 elapses after the predetermined time T1 elapses and then sets the operating state of the PTC heater 30 to the stopped state And then, the above-described operation is repeated.

Hereinafter, the characteristic effects of the present embodiment will be described.

(1) When the PTC heater 30 is in the driving state and at the same time the operating state of the sample holder 21 does not change for a predetermined time, the control section 61 controls the cover section 13b to be higher than the upper limit temperature A, Is higher than the surface temperature. The control unit 61 switches the operating state of the PTC heater 30 from the driving state to the stopping state when the control unit 61 determines that the surface temperature of the cover portion 13b is higher than the upper limit temperature A. As described above, the massage device 10 is configured to operate based on the operation state of the sample handler 21 during the driving of the PTC heater 30 and the time (predetermined time T1) during which the operating state of the PTC heater 30 continues The surface temperature of the cover portion 13b can be deduced by deducing the surface temperature of the cover portion 13b to an appropriate temperature. Accordingly, the massage machine 10 can apply a more suitable thermal sample to the user.

(2) When the PTC heater 30 is in operation and the operation state of the sample holder 21 is not changed for a predetermined time, the control unit 61 determines that the surface temperature of the cover portion 13b is higher than the upper limit temperature A Analogy. The control section 61 changes the operating state of at least one of the PTC heater 30 and the sample hand 21 when the control section 61 determines that the surface temperature of the cover section 13b is higher than the upper limit temperature A . The massager 10 can control the surface temperature of the cover portion 13b based on the operating state of the sample holder 21 and the operating state of the PTC heater 30 during driving of the PTC heater 30. [ And the surface temperature of the cover portion 13b can be lowered to an appropriate temperature. Accordingly, the massage machine 10 can apply a more suitable thermal sample to the user.

(3) When the surface temperature of the inferred cover portion 13b is higher than the upper limit temperature A, the control unit 61 stops the driving of the PTC heater 30. Since the driving of the PTC heater 30 is stopped when the surface temperature of the inferred cover portion 13b is higher than the upper limit temperature A which is an appropriate temperature, The temperature can be lowered to an appropriate temperature. Accordingly, the massage machine 10 can apply a more suitable thermal sample to the user.

(4) When the surface temperature of the covered cover portion 13b is higher than the upper limit temperature A, the control unit 61 drives the sample holder 21 to change the position of the sample holder 21. The massager 10 is provided with a part (part of the user's body) of the user's body because the position of the sample holder 21 is changed when the surface temperature of the inferred cover part 13b is higher than the upper limit temperature A, It is possible to apply a suitable warm sample to suppress excessive warming of the sample.

(5) The backrest 13 is provided with an airbag 70 for performing air massage to the user by the expansion and contraction movement of the backrest 13 in the front-back direction. The controller 61 expands the airbag 70 to expand the interval between the PTC heater 30 and the user's body when the surface temperature of the covered cover portion 13b is higher than the upper limit temperature A. [ Since the user's body is separated from the PTC heater 30 by the airbag 70 when the surface temperature of the covered cover portion 13b is higher than the upper limit temperature A, May be provided with a suitable warm sample to inhibit excessive warming of a part of the user's body.

The embodiment of the present invention may be modified as follows.

In the above-described embodiment, when the operation state of the massage ball 24 (specimen holder 21) is not changed for the predetermined time T1 in the driving (on) state of the PTC heater 30, The driving of the heater 30 is in a stopped (off) state, but is not limited thereto.

8, when the operation state of the massage ball 24 (specimen holder 21) is not changed during the predetermined time T1 in the driving state of the PTC heater 30, A configuration may be adopted in which the position of the magnet 21 is changed. In this case, since the massage device 10 does not stop the driving of the PTC heater 30, the warm sample can be directly applied to other body parts of the user after the position of the sample holder 21 is changed.

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 massager 10 is capable of being operated in a relatively long time during which the user's body (the cover portion 13b) comes into contact with the sample member 21 (massage ball 24) It is possible to lower the surface temperature of the cover portion 13b by using a configuration in which the time is changed to a relatively short tapping operation.

An airbag 70 (indicated by a broken line in Fig. 1) capable of expanding and contracting along the longitudinal direction may be provided in the backrest portion 13 of the massage machine 10, for example, in addition to the above-described configuration. 9, when the operation state of massage ball 24 (specimen holder 21) does not change for the predetermined time T1 in the driving state of PTC heater 30, controller 61 and / The air pump 71 inflates the airbag 70 and may allow the user's body (the cover portion 13b) to be separated from the PTC heater 30. [ In this configuration, since the driving of the PTC heater 30 is not stopped, the massage machine 10 can immediately apply the hot sample to the other body parts of the user after the position of the sample needle 21 is changed. In addition, by providing the airbag 70, the massager 10 can perform air massage using the airbag 70. [ Further, the airbag 70 may be appropriately changed to any position of the backrest 13. [

Although the thermistor 42 for measuring the temperature of the PTC heater 30 (the second case member 32) is provided in the second case member 32 in the above embodiment, the present invention is not limited to this, 42 may be omitted. In this case, for example, the temperature of the PTC heater 30 may be estimated in advance by experiment, and the temperature of the PTC heater 30 may be inferred.

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