[0006] Inside the massage device, power supply lines for supplying power to each unit are required for wiring. Regarding the wiring, there are problems such as troublesome work and ensuring space for wiring. Also, there are costs for the power supply lines and the period for preparing components, etc., or problems such as disconnection or entanglement of the power supply lines due to the operation of the massage units may occur. Therefore, it is desired to suppress the wiring inside the massage device.

[0007] According to one embodiment, the massage device includes: one or more massage units; a power supply unit that receives power supply from the outside; and a power transmitter that transmits the power of the power supply unit by wireless means. At least one of the massage units includes a wireless power receiving circuit so as to be able to receive the power transmitted from the power transmitter.

[0017] <1. Outline of the massage device>

[0018] (1) The massage device according to the embodiment includes: one or more massage units; a power supply unit that receives power supply from the outside; and a power transmitter that transmits the power of the power supply unit wirelessly. At least one of the massage units includes a wireless power receiving circuit so as to be able to receive the power transmitted from the power transmitter.

[0019] The massage unit is an action mechanism for performing a massage operation on the user's body, and is arranged at various parts of the massage device. By wirelessly transmitting power from the power supply unit and being able to receive it in at least one of the massage units, the wiring trouble inside the massage device can be suppressed. Therefore, it is easy to manufacture. And since the space for wiring can be reduced, the enlargement can be suppressed.

[0020] (2) Preferably, the massage unit further includes a converter for converting the voltage of the power received by the wireless power receiving circuit. Thereby, even when the operating voltage of the massage unit is different from the voltage of the power supplied from the power supply unit, the power corresponding to the operating voltage can be supplied.

[0021] (3) Preferably, the massage unit further includes a battery that can store the power received by the wireless power receiving circuit. Thereby, the massage unit operates using the power stored in the battery. Therefore, for example, even when the power required to drive the massage unit is greater than the power supplied wirelessly, power can be supplied. And when the massage unit is a movable unit that moves inside the massage device, even when the massage unit moves outside the range where power can be transmitted from the power transmitter, power can be supplied.

[0022] (4) Preferably, the massage unit further includes: a battery that can store the power received by the wireless power receiving circuit; and a converter for converting the voltage of the power output from the battery. Thereby, even when the operating voltage of the massage unit is different from the voltage of the power supplied from the power supply unit, the power corresponding to the operating voltage can be supplied.

[0023] (5) Preferably, the massage unit includes a movable unit that can move within the massage device during the massage operation, and the movable unit includes a battery. Thus, even when the massage unit moves and the positional relationship with the power transmitter changes, power can be supplied.

[0024] (6) Preferably, the power transmitter transmits power when the movable unit is in a specified position, and stops transmitting power when the movable unit starts to move from the specified position. Thus, when the positional relationship between the movable unit and the power transmitter changes, power is supplied from the battery instead of wireless power supply.

[0025] (7) Preferably, the movable unit is in an initial position different from the massage position where the massage operation is performed before the massage operation starts. The power transmitter stops transmitting power to the movable unit when the massage operation starts. After the power transmission stops, the movable unit moves from the initial position to the massage position using the power of the battery, and thus the massage operation starts. Thus, when the massage operation starts, wireless power supply is stopped, and then it moves to the massage position. Therefore, during the massage operation, power is supplied from the battery.

[0026] <2. Example of massage device>

[0027] The concept of direction used in the following description is consistent with the concept of direction as observed from a user of the massage device 1 included in the massage system 100 shown. For other cases, appropriate explanations will be given. Also, for the definition of the front and back of the body, the chest side of a standing user is defined as the "front surface", and the back side is defined as the "back surface" for explanation. Figure 1 Referring to

[0028] Reference Figure 1 , the massage system 100 includes: a massage device 1, that is, a massage machine main body; and a tablet 10 that functions as a controller of the massage device 1. The massage device 1 is preferably a seat type for the user to sit on, that is, a massage chair, and there is no limitation on forms such as a cushion type, a bed type, a handheld type, and a placement type.

[0029] The tablet 10 is constituted by an external device of the massage device 1. An external device of the massage device 1 is a device different from the massage device 1, and refers to a device that exists entirely outside the massage device 1. By "existing outside the massage device 1" it means outside the cover that covers the entire massage device 1, the whole can exist away from the massage device 1, and is controlled by an independent control mechanism separated from the control mechanism of the massage device 1.

[0030] The massage device 1 mainly includes: a seat portion 2 for the user to sit on; a backrest portion 3 provided at the rear of the seat portion 2 in a reclining manner for the user to lean on; a footrest 4 provided at the front of the seat portion 2 in a vertically swingable manner to support the lower limbs of the user; a headrest portion 5 provided in front of the upper part of the backrest portion 3 to support the head and / or neck of the user; armrest portions 6 (armrests) on the left and right sides of the seat portion 2; and side wall portions 7 on the left and right sides of the backrest portion 3. The seat portion 2, the backrest portion 3, the footrest 4, the headrest portion 5, the armrest portions 6, and the side wall portions 7 function as body support portions for supporting the user's body.

[0031] At each part of the body support portions 2 to 7, a plurality of action mechanisms for performing a massage action on the user's body, that is, massage units, are provided. The air massage unit 15 is an action mechanism that performs a massage action based on an airbag 20 or the like. The airbag 20 is an airbag that expands and contracts by the supply and discharge of air, and it can press the user by supplying and discharging air.

[0032] A pump unit 9 as a massage unit is provided below the seat portion 2. Refer to Figure 2 , the pump unit 9 includes a pump 93 and a drive circuit 91 that controls the drive of the pump 93, and supplies and discharges air to and from the air massage unit 15 including the airbag 20.

[0033] The pump unit 9 includes a communication unit 92 for communicating with a main substrate 21 described later. The communication unit 92 receives a control signal for a command action from the tablet 10 via the main substrate 21. The drive circuit 91 controls the drive of the pump 93 according to the control signal from the tablet 10, thereby controlling the supply and discharge of air to and from the air massage unit 15.

[0034] Refer to Figure 2 , the air massage unit 15 including the airbag 20 includes a drive circuit 51 having a valve (not shown) that supplies and discharges air from the pump unit 9 to and from the airbag 20.

[0035] The air massage unit 15 includes a communication unit 52 for communicating with a main substrate 21 described later. The communication unit 52 receives a control signal for a command action from the tablet 10 via the main substrate 21. The drive circuit 51 controls the supply and discharge to and from the airbag 20 according to the control signal from the tablet 10.

[0036] The air massage unit 15 may further include a pressure sensor 53. The pressure sensor 53 detects the pressurization caused by the expansion of the airbag 20. The pressurization caused by the expansion of the airbag 20 corresponds to the massage intensity based on the air massage unit 15. The communication unit 52 sends a sensor signal from the pressure sensor 53 to the tablet 10 via the main substrate 21.

[0037] In addition, the air massage unit 15 can replace the airbag 20 or, in addition thereto, include a vibrator and perform a massage action based on the vibrator. The vibrator can apply vibration to the user by rotating an eccentric weight. In this case, the drive unit is a motor that drives the vibrator.

[0038] In addition, as Figure 1 shown, the massage device 1 has a mechanical massage unit 8 as a massage unit on the backrest 3. The mechanical massage unit 8 is an action mechanism for performing massage actions such as kneading actions and / or pounding actions described later. The mechanical massage unit 8 massages the upper body of the user from the rear (back side). The mechanical massage unit 8 is a movable unit that can move in the vertical direction indicated by the arrow A in Figure 1 . A plurality of (one in this embodiment) mechanical massage units 8 can be provided in the height direction.

[0039] Refer to Figure 2 , the mechanical massage unit 8 has a massage motor M1 composed of one or more motors. The massage motor M1 is one of the actuators for performing massage actions.

[0040] As a massage component, the mechanical massage unit 8 has a pair of left and right arms (not shown) provided with treatment members at the upper and lower ends. The massage motor M1 can perform a kneading action of bringing the left and right treatment members closer to or farther from each other and a pounding action of alternately advancing and retreating the left and right treatment members toward the user side by driving.

[0041] The mechanical massage unit 8 has a lifting motor M2. The lifting motor M2 is an actuator for performing massage actions and is one of the actuators for moving the mechanical massage unit 8 as shown by the arrow A in Figure 1 .

[0042] The mechanical massage unit 8 is moved on a guide rail 33 ( Figure 4 ) by driving the lifting motor M2 and using a lifting mechanism (not shown) composed of a rack and a pinion, etc. As shown in Figure 4 , the guide rail 33 is provided to extend in the height direction on the backrest 3. Therefore, as shown by the arrow A in Figure 1 , the mechanical massage unit 8 moves upward or downward in the height direction, whereby the position relative to the body can be changed or rolling massage can be performed.

[0043] The mechanical massage unit 8 includes a communication unit 82 for communicating with the main substrate 21 described later. The communication unit 82 receives a control signal for commanding an action from the tablet 10 via the main substrate 21. The drive circuit 81 controls the drive of the massage motor M1 or the lifting motor M2 according to the control signal from the tablet 10. In addition, the communication unit 82 sends a signal indicating the drive state of the massage motor M1 or the lifting motor M2 to the tablet 10 via the main substrate 21.

[0044] The massage device 1 has a sensor unit 13 as a massage unit. The sensor unit 13 has a sensor 31. The sensor 31 detects the degree of massage action or the state of the user. The sensor 31 detects, for example, the position of the mechanical massage unit 8, the presence or absence of the user on the seat 2 or the backrest 3, and the like.

[0045] The sensor unit 13 includes a communication unit 32 for communicating with a main substrate 21 described later. The communication unit 32 transmits a sensor signal generated by the sensor 31 to the main substrate 21 .

[0046] The massage device 1 has a reclining unit 16 as a massage unit. The reclining unit 16 adjusts the angle of the backrest 3 according to the massage action. Figure 1 The unit is changed as shown by arrow B, and includes an actuator 63 that changes the angle and a drive circuit 61 that drives the actuator 63.

[0047] The reclining unit 16 includes a communication unit 62 for communicating with a main substrate 21 described later. The communication unit 62 receives a control signal for commanding an action from the tablet 10 via the main substrate 21. The drive circuit 61 controls the drive of the actuator 63 according to the control signal from the tablet 10. In addition, the communication unit 62 transmits a signal indicating the drive state of the actuator 63 to the tablet 10 via the main substrate 21.

[0048] refer to Figure 3 The tablet 10 has a user operation unit 11. The user operation unit 11 includes buttons, etc., receives user operations, specifies the contents of the massage action indicated, and outputs a first signal E11 indicating the execution of the massage action to the main substrate 21.

[0049] The massage device 1 can execute a massage routine. A massage routine is a combination of predetermined massage actions, in which massage actions such as kneading or beating, as well as duration and execution order, are predetermined.

[0050] The tablet 10 further includes a massage program execution processing unit 12. The massage program execution processing unit 12 includes a processor such as a CPU (Central Processing Unit) and a memory for storing a massage program executed by the processor.

[0051] When the user operation received by the user operation unit 11 is an operation instructing the execution of a massage process, the user operation unit 11 transmits the user operation to the massage program execution processing unit 12.

[0052] In the massage program execution processing unit 12, when the execution of a massage process is instructed by a user operation, the processor executes the massage program. By executing the massage program, the processor designates a massage action according to the massage process for the massage device 1 and outputs a first signal E12 indicating the execution to the main board 21.

[0053] The massage device 1 has a main board 21. The main board 21 communicates with the tablet 10 and receives the first signal E11 or E12 from the tablet 10. The main board 21 controls the drive circuits of the respective massage units based on the first signal E11 or E12.

[0054] Specifically, the main board 21 stores the massage units to be actuated and their operation contents for each massage action content specified by the first signals E11 and E12. Regarding the operation contents, for example, in the case of the mechanical massage unit 8, they are the on, off, rotation speed, rotational speed, etc. of the massage motor M1. In the case of the air massage unit 15, they are the on, off, etc. of the electromagnetic valves (not shown) included in the airbag 20.

[0055] The main board 21 outputs a signal (second signal) commanding the required operation to the required drive circuit according to the first signals E11 and E12, such as outputting the second signal E21 to the drive circuit 51 and outputting the second signal E22 to the drive circuit 81.

[0056] The drive circuits receiving commands from the main board 21 respectively output a pre-specified signal to the actuator for actuating the actuator to be controlled. For example, the drive circuit 51 of the air massage unit 15 outputs the on, off signal (third signal E31) of the electromagnetic valve of the airbag 20 to the airbag 20 according to the second signal E21 from the main board 21. The drive circuit 81 of the mechanical massage unit 8 outputs, for example, a drive signal (third signal E32) of the massage motor M1 such as a PWM (Pulse Width Modulation) signal to the massage motor M1.

[0057] The massage device 1 also has a power supply unit 17. The power supply unit 17 receives power supply from the outside through the connection wire 71A. The power supply unit 17 includes a power supply circuit 71 for supplying the supplied power to the massage units.

[0058] Regarding the power supply from the power supply unit 17 to the massage units, at least one massage unit is supplied with power wirelessly. The massage device 1 includes a massage unit that receives power supply through wireless communication, thereby being able to suppress the trouble of wiring inside the massage device 1. Therefore, it is easy to manufacture. Also, since the space for wiring can be reduced, the enlargement can be suppressed. In addition, among the multiple massage units, there may also be a massage unit that receives power supply from the power supply unit 17 by a wired method.

[0059] Reference Figure 2 and Figure 4 , the power supply unit 17 is arranged below the seat portion 2 of the massage device 1 and near the pump unit 9 that is also arranged below the seat portion 2. As Figure 2 shown, the pump unit 9 has a power receiving circuit 94 for receiving power supply from the power supply unit 17. The power receiving circuit 94 is connected to the power supply circuit 71 through a conducting wire and receives the power supply from the power supply circuit 71. This is because when the power supply amount per unit time of the wired method is larger than that of the wireless communication method of power supply, for the pump unit 9 with a relatively large required power, the wired method can increase the supply amount per unit time. Also, since the pump unit 9 is close to the power supply unit 17, the wiring is not troublesome.

[0060] The power supply unit 17 also has a power transmitter 72 and a power transmission control unit 73. The power transmitter 72 supplies power to the massage unit through wireless communication. The power transmission control unit 73 controls the power transmission of the power transmitter 72 based on a signal from the main substrate 21 described later.

[0061] The massage unit that receives power supply from the power supply unit 17 through wireless communication has a wireless power receiving circuit. Reference Figure 2 , the sensor unit 13 has a wireless receiving circuit 34. The reclining unit 16 has a wireless power receiving circuit 64. As Figure 1 and Figure 4 shown, the sensor unit 13 and the reclining unit 16 are arranged below the backrest 3 as an example and receive power supply wirelessly from the power transmitter 72 arranged below the seat portion 2.

[0062] The air massage unit 15 has a wireless power receiving circuit 54. As Figure 1 and Figure 4 shown, the air massage unit 15 is arranged at various parts such as the backrest 3, the footrest 4, the headrest 5, the armrest 6, and the side wall portion 7. Therefore, when power is supplied wirelessly, the wiring can be greatly reduced.

[0063] In addition, as Figure 4As shown, the power supply unit 17 may further include a second power transmitter 72A. The second power transmitter 72A is disposed at a position separated from the power transmitter 72, relays the power from the power transmitter 72, and transmits it to the massage unit.

[0064] For example, in the Figure 4 example, it is assumed that the wireless power receiving circuit 54 of the air massage unit 15 disposed on the footrest 4 has difficulty receiving the power transmitted from the power transmitter 72. In this case, the second power transmitter 72A can be disposed at an intermediate position between the wireless power receiving circuit 54 and the power transmitter 72, relays the power from the power transmitter 72, and transmits it to the wireless power receiving circuit 54. In addition, the power supply from the power transmitter 72 to the second power transmitter 72A can be wired or wireless.

[0065] The mechanical massage unit 8 has a wireless power receiving circuit 84. As Figure 4 shown, when the mechanical massage unit 8 is in the initial position described later, it is disposed below the backrest 3 and receives power supply wirelessly from the power transmitter 72 disposed below the seat 2.

[0066] Various wireless power supply methods can be adopted in the power transmitter 72. For example, an electromagnetic induction method, a magnetic resonance method, an electric field coupling method, a radio wave reception method, etc. can be cited. Wireless power supply can be performed by a single power supply method, or multiple power methods can be adopted according to the distance from the massage unit or the required power, etc.

[0067] As an example, taking the case of power supply by the radio wave reception method as an example, use Figure 5 to explain the power supply process. For the wireless power receiving circuit, the wireless power receiving circuit 84 of the mechanical massage unit 8 is taken as a representative for explanation.

[0068] Refer to Figure 5 The power supply circuit 71 of the power supply unit 17 includes an AC / DC conversion circuit 75. The AC / DC conversion circuit 75 converts the DC voltage input from the outside via the wire 71A into an AC voltage.

[0069] The power transmitter 72 includes a power transmission circuit 76 and an antenna 77. The power transmission circuit 76 includes a semiconductor oscillator, etc. The power transmission circuit 76 generates an electromagnetic wave for transmitting the power converted into AC by the AC / DC conversion circuit 75 according to a command from the main board 21.

[0070] The antenna 77 radiates the electromagnetic wave E generated by the power transmission circuit 76. The electromagnetic wave is, for example, a microwave of 2.45 GHz.

[0071] The wireless power receiving circuit 84 has an antenna 87. The antenna 87 receives the electromagnetic wave E radiated from the antenna 77.

[0072] The wireless power receiving circuit 84 also has a rectifying circuit 88. The rectifying circuit 88 converts the high-frequency received current received by the antenna 87 into a direct current.

[0073] The mechanical massage unit 8 also has a battery 85. The battery 85 can store the power output from the wireless power receiving circuit 84. The power stored in the battery 85 is supplied to the drive circuit 81.

[0074] When the drive voltage is different from the voltage received from the power supply unit 17, the massage unit further includes a converter for converting the voltage. In Figure 5 this case, the mechanical massage unit 8 has a converter 86, and the power output from the rectifying circuit 88 has its voltage converted by the converter 86 and is stored in the battery 85. As Figure 2 shown, similarly, the air massage unit 15 and the reclining unit 16 also respectively include converters 56 and 66. Thereby, power corresponding to the operating voltage is supplied.

[0075] In addition, the power output from the rectifying circuit 88 can be stored in the battery 85 without voltage conversion. In this case, the converter 86 converts the voltage of the power output from the battery 85 and supplies it to the drive circuit 81. In this case, power corresponding to the operating voltage can also be supplied.

[0076] Batteries can also be included in massage units other than the mechanical massage unit 8. For example, as Figure 2 shown, the reclining unit 16 includes a battery 65. As in the case of the reclining unit 16, when the driving power is large, power supply can be performed as follows: the battery 65 is charged during the period when the massage device 1 is not operating, and this power is used for driving during operation. Thereby, the shortage part in wireless power supply can be ensured.

[0077] In a movable unit such as the mechanical massage unit 8, the positional relationship with the power supply unit 17 changes according to the massage action, so wireless power supply during the massage action is sometimes not suitable. In this case, wireless power supply is performed and stored in the battery 85 in non-massage when the massage device 1 does not perform a massage action, and power is supplied from the battery 85 without wireless power supply during the massage action.

[0078] The execution and stop of wireless power supply to the movable unit can be achieved through Figure 6 the power supply control. During non-massage and when the massage action is being performed, the positional relationship between the mechanical massage unit 8 and the power supply unit 17 changes as Figure 7 and Figure 8 shown. Figure 6The control shown in the flowchart can also be performed by the CPU in the massage program execution processing unit 12 of the tablet 10.

[0079] As Figure 7 shown, when the massage device 1 is not performing a massage action (non-massage), the mechanical massage unit 8 is arranged at the initial position P0. The initial position P0 is a position where power can be received wirelessly from the power transmitter 72 by the wireless power receiving circuit 84. As an example, it is the lower part of the backrest 3 as Figure 7 shown.

[0080] When the massage action starts, as Figure 8 shown, the mechanical massage unit 8 is located at the massage position P1. The massage position P1 is above the backrest 3 and is approximately near the shoulders of the seated user. In addition, the massage position P1 can be changed according to the massage action specified in the massage process or the detected body type of the user, etc.

[0081] In non-massage, the mechanical massage unit 8 is located at the initial position P0. In non-massage, the CPU of the tablet 10 instructs the main board 21 to supply power to the mechanical massage unit 8. According to this instruction, wireless power supply is performed to the mechanical massage unit 8 (step S101). In non-massage, the power received by the wireless power receiving circuit 84 is stored in the battery 85.

[0082] When the main board 21 receives the above instruction from the tablet 10, as Figure 5 shown, a signal T1 is output to the power receiving control unit 89 and its response is obtained. The response can be, for example, a signal indicating the current position. According to the response, when the wireless power receiving circuit 84 can receive power, the main board 21 outputs a signal T2 instructing power transmission to the power transmission control unit 73. In addition, according to the signal T2 from the main board 21, the power transmission control unit 73 can send a signal T3 to the power receiving control unit 89 and start power transmission according to its response.

[0083] When a user operation instructing the execution of the massage process is received in the user operation unit 11 (Yes in step S103), the CPU of the tablet 10 sends a signal instructing the stop of wireless power supply to the main board 21. Thereby, the wireless power supply is stopped (step S105).

[0084] After stopping the wireless power supply to the mechanical massage unit 8 in step S105, the CPU executes the massage action according to the massage process (step S107). Specifically, the CPU moves the mechanical massage unit 8 from the initial position P0 ( Figure 7 ) to the massage position P1 ( Figure 8)。That is, based on the signal from the tablet 10, the main substrate 21 instructs the drive circuit 81 to drive the lifting motor M2. Thereby, the mechanical massage unit 8 moves along the guide rail 33 from the initial position P0 ( Figure 7 ) to the massage position P1 ( Figure 8 ). After that, a massage action according to the massage process is executed.

[0085] At this time, power is supplied to the drive circuit 81 of the mechanical massage unit 8 from the battery 85 instead of the power supply unit 17. By storing electricity in the battery 85 during non-massage, power can be ensured even without wireless power supply during the massage action.

[0086] When all the massage actions according to the instructed massage process are completed, the CPU returns the mechanical massage unit 8 to the initial position P0 ( Figure 7 )(step S109). Here, based on the signal from the tablet 10, the main substrate 21 instructs the drive circuit 81 to drive the lifting motor M2. Thereby, the mechanical massage unit 8 moves along the guide rail 33 from the massage position P1 ( Figure 8 ) to the initial position P0 ( Figure 7 ).

[0087] After the mechanical massage unit 8 returns to the initial position P0 ( Figure 7 ), the CPU again instructs the main substrate 21 to supply power to the mechanical massage unit 8. According to this instruction, the wireless power supply state to the mechanical massage unit 8 is restored (step S111).

[0088] By repeating Figure 6 's control, it is possible to wirelessly supply power to the mechanical massage unit 8 during non-massage and store the power in the battery 85, and supply power from the battery 85 without wireless power supply during the massage action.

[0089] The execution and stop of the wireless power supply to the movable unit can use sensors in addition to the control based on the CPU. For example, the power transmission control unit 73 may have a sensor that detects that the mechanical massage unit 8 is near the power transmitter or the initial position P0. When it is in the initial position P0, the power transmitter 72 is made to transmit power, and when it is not in the initial position P0, power transmission is not performed.

[0090] In addition, wireless power supply can also be continued during the massage operation. In this case, the CPU of the tablet 10 monitors the operation status of the mechanical massage unit 8 via the main board 21 and detects power shortage during the massage operation. Regarding the power shortage, for example, it can be detected by comparing the rotation speed of the massage motor M1 with a threshold value of the preset rotation speed. If power shortage is detected, the CPU of the tablet 10 sends a signal instructing to stop the wireless power supply to the main board 21 and stops the wireless power supply. Thereby, power can be supplied from the battery 85 to the drive circuit 81 of the mechanical massage unit 8 instead of from the power supply unit 17. In this way, wireless power supply can also be continued during the massage operation. By supplying power from the battery 85 when power shortage is detected, power can be ensured even in this case.
