Description

Technical Field [0001] The present invention relates to a heating assembly for a massage chair with airbag,

The present invention relates to a heating assembly for use in a massage chair. More specifically, the present invention relates to a heating assembly capable of separately providing an massage ball for performing a massage function and a heating element for performing a heating function, and also providing an air bag with a feeling of pressure.

Many people get massages to relieve the stiff body caused by stress, muscular bunching due to lack of exercise. However, massage masseurs can not receive massages for various reasons, so massage chairs which can be conveniently provided at home have been developed and used.

There are various kinds of massage chairs, but a massage ball assembly is mounted on the inner side of the backrest portion to massage the warm ball to the muscles of the back portion and to transmit the warm feeling.

As a patent document relating to a warm ball assembly, Korean Patent No. 10-1479521, Japanese Laid-Open Patent Application No. 2013-066509, Korean Laid-Open Patent Application No. 2002-0078516, and the like can be given.

The conventional thermal ball assembly includes a bracket that supports the thermal ball and transmits power for generating heat (through another wire or the like) and is movable up and down. And a plurality of hot balls made of the same material. A hot wire or a sheath heater is built in the hot ball, and receives power from the power supply unit to generate heat. In addition, since the heated ball is fixed to the bracket, the bracket moves together when it is moved up and down or left and right. At the same time, it rotates itself in a state fixed to the bracket to provide a massage feeling. That is, the hot ball is moved up and down together with (1) the heat generation, (2) the up and down movement of the bracket, and (3) At the same time.

Such a conventional warm ball assembly has the following problems.

First, bracket heating problems. Since the bracket is directly connected to the shaft member of the warm ball so as to fix the warm ball, when the heated ball is heated, the bracket receives heat and is heated. However, since the bracket is generally made of a hard metal material in order to withstand the load and is generally made of a soft material such as rubber to provide a massage feeling of the warm ball, when the power is supplied to heat the warm ball, And is heated to a higher temperature. In reality, in many massage chairs, the user feels a sense of warmth due to the heating of the bracket, not heating the heated ball directly. The heat loss through the bracket causes not only the power loss but also the problem of lowering of the thermal sensation upon massage, and the problem of decreasing the durability of the bracket due to repeated heating and cooling of the metal material bracket.

Second, in order to solve the first problem, it is possible to apply other materials such as ceramics, which have a higher heat transfer coefficient than metal bracket, to the heated balls, but the heated balls made of such materials cause noise during self rotation. Considering that most of the warm ball assemblies are mounted adjacent to the back or neck of the user, the noise problem is a drawback that can not be overlooked.

Third, in order for the heating ball to generate heat, it is necessary to apply electric power to the rotating heating ball, which makes the structure of the heating ball complicated, making it difficult to manufacture, and causing frequent failure. If a hot ball of a complicated structure fails, it must be replaced with a new hot ball, which inconveniences the user as well as the economic burden of the manufacturer.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems.

In order to provide a massage feeling, a warm ball must be provided in the bracket and rotated. At the same time, since the user should be provided with a sense of thermal sensation, a massager that satisfies the conditions of simultaneously providing massage sensation and thermal sensation, To provide a self heating heat sink assembly.

That is, there is an attempt to solve the problem of excessive heat generation of the bracket, to prevent a noise problem at the same time, and to provide a heat generating assembly which is simple in structure of a warm ball.

In addition, when a user uses a massage chair including a conventional heating assembly, he or she can not feel the pressure feeling desired by the user and the satisfaction is lowered.

According to an aspect of the present invention, A plurality of massage balls 610 rotatably mounted on the bracket 630; A massage pack 650 to which the bracket 630 is fixed and which can perform at least one of up-down motion and left-right motion; A heating body 620 mounted on the massage mass 650 or the bracket 630 and positioned adjacent to the massage balls 610; And an airbag (619) having one end fixed to the bracket (630), the airbag (619) being located adjacent to the plurality of massage balls (610), the heating assembly including a backrest (100). ≪ / RTI >

The heating assembly is preferably reciprocated in a direction toward the backrest part 100 of the massage chair by adjusting the air amount of the airbag 619.

In addition, it is preferable that the heating assembly perform at least one of up-down movement and left-right movement while air is being injected into the airbag 619.

In addition, it is preferable that the air amount of the airbag 619 is controlled in multiple stages.

Further, when the stretching mode is applied to the massage chair, air is preferably injected into the airbag 619.

In addition, when the heating element 620 is heated, it is preferable that air is injected into the airbag 619.

According to an aspect of the present invention, there is provided a massage chair comprising: a seat portion; The backrest part 100 rotatably fixed to one side of the seat part 200; A leg fixing part 300 rotatably fixed to the other side of the seat part 200; A support frame 400 for fixing the seat portion 200; The heating assembly 600 mounted on the back 100 and being capable of being vertically or horizontally moved by the massager 650; And an operating portion capable of controlling the rotation of the backrest portion 100 and the rotation of the leg fixing portion 300 and the upward and downward movement or the left and right movement of the heating assembly 600 and the heating of the heating body 620 500). ≪ / RTI >

The operation unit 500 controls the air volume of the air bag 619 to reciprocate the massage ball 610 and the heating element 620 of the heating assembly 600 in the direction toward the back desirable.

The massage ball is deviated from the paradigm that the massage feeling and the thermal feeling are provided to the user at the same time because the massage ball itself needs to be heated so that the massage ball performing the massage function and the heating body performing the heat generating function are separately adopted. This is because, since the heat-generating assembly mounted on the backrest of the massage chair and a somewhat thick outer portion (leather sheet, etc.) are located between the back or shoulder of the user, heat is generated in the adjacent area without necessarily heating the massage ball itself If you move up / down / left / right with the massage ball, you can feel the feeling of massage and thermal sensation at the same time.

In particular, since the heating element is made of a material having a higher heat transfer coefficient than the heat transfer rate of the bracket, it is possible to prevent a phenomenon that the bracket is heated excessively and the durability of the bracket is weakened.

Further, since the heating element is disposed adjacent to the massage ball, the user can simultaneously feel the thermal feeling and the massage feeling similar to the heating of the massage ball.

Further, by locating the airbag adjacent to the massage ball, it is possible to provide the same effect as moxibustion pressure.

Due to such a structure, the material of the massage ball can be freely selected as a material which can give an optimum massage feeling but does not cause noise, so that a massage feeling superior to that of a conventional massage chair can be provided.

Explanation of the heating assembly

One of the distinguishing features of the heat generating assembly 600 according to the present invention from the prior art is that the massage ball 610 provides the user with a sense of heat without heating.

In the massage chair according to the related art, in order to simultaneously provide the massage feeling and the thermal feeling to the user, the massager ball touching the user's shoulder or shoulder must rotate while generating heat, and the present inventors have confirmed that this problem arises in this part.

The massage ball 610, which provides a massage feeling by touching the back or shoulder of the user, is not heated but only rotates and moves up and down / left and right only, and a separate heating element 620 is provided to the massage ball 610, So that it is mounted on the massage pad 650 or the bracket 630 so that the user can feel the massage feeling and the thermal sensation as in the prior art.

A heat generating assembly 600 according to the present invention will be described in more detail with reference to Fig.

The heating assembly 600 includes a plurality of massage balls 610 that are mounted on the backrest 100 in the massage chair and are rotatable, an airbag 619 and a heating body 620 positioned adjacent to the massage ball 610, A bracket 630 for fixing the massage ball 610, the airbag 619 and the heat generating element 620 and a bracket 630 fixed to support the bracket 630. The entire heating assembly 600 may be moved up and down, And a massage mass 650 for supplying electric power to the massager 650.

The massage ball 610 does not generate heat separately, and moves upwardly or downwardly or right and left together with the massage pad 650 when moving up and down or right and left. At this time, it is possible to rotate naturally by moving up and down or left and right while touching the back or shoulder part of the user, and massage feeling is transmitted to the user by the rotation of the massage ball 610.

The material of the massage ball 610 may be any material for providing an optimal massage feeling to the user and minimizing noise during rotation. In the prior art, the massage ball itself needs to be made of a heat-resistant material or a material having a good heat transfer ratio. In view of this, the massage ball is somewhat poor in quality or noise during rotation. It is not necessary to consider the heat transfer rate, so that any material suitable for the purpose of the massage chair can be selected from elastic rubber or synthetic resin series.

The airbag 619 is fixed at one end to the bracket 630, and is located adjacent to the plurality of massage balls 610. The airbag 619 adjusts the amount of air located inside the airbag 619 to reciprocate the massage ball 610 in the direction toward the backrest part 100 of the massage chair.

In addition, the amount of air in the airbag 619 can be adjusted in multiple stages, and with the air being introduced into the airbag 619, the heating assembly according to the present invention performs at least one of up-down movement and left-right movement. In this case, the massage ball 610 can provide the user with a feeling of massage by the pressure separately, and the massage ball 610 and the other heat generating assembly can give the user the same effect as the moxibustion pressure by giving the heat feeling and the pressure feeling at once . To this end, in one embodiment, when the heating element 620 to be described later is heated, air can be injected into the airbag 619.

In another embodiment, the airbag 619 can inject air into the interior of the massage chair when the stretching mode is applied, thereby providing the user with the pressure for stretching.

The heating element 620 is installed at a predetermined distance from the bracket 630 or the massage pad 650. In an embodiment, the heating element 620 is mounted on the bracket 630.

The heating body 620 mounted on the bracket 630 receives power through a wire (not shown) provided in the massage mass 650 and the bracket 630 in a separate power supply unit (not shown) to generate heat. The specific structure for generating heat may be any structure, for example, a structure employing a heat wire or a sheath heater.

The heating element 620 does not rotate. Therefore, unlike the heating structure according to the related art in which the rotating massage ball generates heat, power can be transmitted as a simple structure.

The number of the heating elements 620 is not limited, and the number of the heating elements 620 is the same as the number of the massage balls 610. If the number of the massage balls 610 is the same, a massage feeling can be felt in the massage ball 610 as described later. In the figure, the massage ball 610 and the heating body 620 are shown in total of six by three on the left and right, but the number of the massage ball 610 and the heating body 620 may be smaller or larger.

The heating element 620 should be positioned adjacent to the massage ball 610. In the case of the user, a feeling of warmth is felt around the rotating massage pad 610 while giving a massage sensation, so that the massage effect and the warming sensation are simultaneously felt, and the massage effect is increased. (Not shown), such as a leather sheet or cushion, between the heating assembly 600 and the back or shoulder of the user, even if the heating element 620 located adjacent to the massage ball 610 actually generates heat, The ball 610 can feel the same thermal feeling as the heat.

For this, the heating element 620 is positioned opposite to the massage ball 610 with respect to the bracket 630. That is, the massage ball 610 is positioned on the inner side with respect to the bracket 630, and the heating element 620 is positioned on the outer side.

In addition, since the number of the heating elements 620 is the same as the number of the massage balls 610, even if the user feels a particularly excellent massage feeling in any massage balls 610, the heating elements 620 located opposite to the massage balls 610 ) At the same time.

The bracket 630 supports the massage ball 610 and the airbag 619 and the heating body 620 located adjacent to the massage ball 610 and is connected to the massage pad 650 at the same time, The ball 610 and the heating element 620 are moved together.

The thermal conductivity of the bracket 630 is preferably lower than that of the heat generating element 620. According to the present invention, since the heating element 620 does not perform a massage function, the heating element 620 can be freely configured and made of a material having a thermal conductivity higher than the thermal conductivity of the metal bracket 630 It is possible to prevent the heat from being transferred to the bracket 630 during the heat generation of the heat generating element 620.

It is preferable that the heating element 620 and the bracket 630 are spaced apart from each other by a predetermined distance to further prevent the heat generated in the heating element 620 from being transmitted to the bracket 630.

The bracket 630 is provided with a separate electric wire (not shown) to transmit the electric power supplied from the electric power supply unit (not shown) to the heating body 620. According to the prior art, since the power is supplied to the rotating massage ball, the structure becomes complicated. In the present invention, the structure is simplified since power is supplied to the heating element 620 which does not rotate.

The massage mass 650 is mounted with an actuator (not shown) that receives electric power from a power supply unit (not shown) of the massage chair and performs at least one of up-down movement and left-right motion of the heat-generating assembly 600.

The massage pack 650 also supplies the power supplied from the power supply unit (not shown) to the airbag 619 and the heating body 620 through a separate electric wire (not shown) provided on the bracket 630 or the like.

While the present invention has been described with reference to exemplary embodiments thereof, it will be understood by those of ordinary skill in the art that various changes in form and details may be made therein without departing from the spirit and scope of the present invention as defined by the following claims.
