The dial 640 is made of a transparent resin material, and a power lamp for displaying an energized state is disposed inside the dial 640.

<2> Operation and Action of Heating Mat FIG. 11 is a perspective view showing a state where the heating mat is used in a bed, and FIG. 12 is a schematic view showing a cross section of the state where the heating mat is placed on the bed.

  The heating mat is used under different usage conditions when used by being placed on a futon and when placed on a bed.

  When the heating mat 100 is used while being placed on a futon, since there is a free space around the futon, the controller unit 600 can be installed in a relatively arbitrary place around the futon. Can be used without being fixed to the main body 200 and arranged at a position convenient for the user.

  On the other hand, when the heating mat 100 is used while being placed on the bed 110, in the conventional configuration, the controller unit 600 must be installed and used on the floor surface, and the controller 610 cannot be operated in the sleeping state. It was almost impossible.

  When the heating mat 100 according to the present embodiment is used while being placed on the bed 110, the connector receiving portion 632 of the main body 200 is disposed on the head side of the bed 110 as shown in FIG. The heating mat 100 is ready for use by connecting the connector plug 631 of the controller unit 600 to the connector receiving portion 632 and connecting the power plug 622 of the controller unit 600 to an outlet.

  As shown in FIG. 11, with the heating mat 100 placed on the bed 110, the controller 610 is fixed to the upper surface of the cover 500 with the binding belt 521, so that the controller 610 is placed at the bedside and is in the sleeping state. But it can be easily operated. Further, the power cord 621 extends from the side edge of the bed 110, and the headboard 112 installed on the head side of the bed 110 does not become an obstacle and can be easily connected to an outlet.

  The basic method of using the heating mat is to turn on the power switch by turning the dial 640 of the controller 610, the power lamp is turned on, and the heater unit 300 is energized. The temperature can be set by adjusting the rotation angle of the dial 640.

  As shown in FIG. 12, a part of the heat generated from the heater wire 320 is transmitted to the upper surface side of the heater unit 300 and is transmitted to the user through the blanket 310 and the cover 500. During this time, a part of the heat is transmitted to the blanket 310. And is conducted in the horizontal direction inside the cover 500 and diffuses over a wide area between the blanket 310 and the cover 500 to raise the temperature.

  On the other hand, a part of the heat is transmitted to the lower surface side of the heater unit 300 to heat the resin fibers 410 forming the base cushion material 400 and the air staying in the cavity 420. The heat transmitted to the resin fiber 410 is conducted along the resin fiber 410 and diffused over a wide range to increase the temperature, so that the effect of soaking the wide range of the cushion material is exhibited. Further, the heated air in the heated cavity 420 flows in a random direction along the cavity 420 as indicated by the arrow in FIG. 7, diffuses over a wide range of the base cushion material 400, and increases the temperature. The effect of soaking the wide range of 400 is exhibited. The heat soaked by the base cushion material 400 is mainly transmitted to the upper surface side and is transmitted to the user through the blanket 310 and the cover 500.

In particular, when the user lies down or when the posture is changed, the base cushion material 400 is greatly depressed, and the warmest air in the hollow portion 420 at the center of the base cushion material 400 diffuses toward the outer periphery. However, the air diffused by the closing member 430 provided at the outer peripheral edge is stopped, diffused in the upper surface direction to raise the temperature around the user, and the user can obtain a comfortable heating effect over a wide range. Can do.

  That is, the heat transmitted to the base cushion material 400 is diffused over a wide range as shown by the arrows in FIG. 7 and is soaked, and the soaked heat is transmitted to the user lying on the upper surface of the heating mat 100. The user can obtain a comfortable heating effect over a wide range.

  Further, the heated air that has reached the outer peripheral end portion of the base cushion material 400 along the hollow portion 420 is discharged to the outside from the end surface of the base cushion material 400 by the closing member 430 provided at the outer peripheral end portion. Is suppressed, and wasteful heat dissipation to the outside of the heating mat 100 is suppressed.

  As described above, the heating mat 100 according to the present embodiment includes a three-dimensional three-dimensional network-like base cushion material 400 having a large number of hollow portions 420 therein, thereby providing a heat insulation effect by air insulation. The heater unit 300 installed above the cushion material 400 is provided with a function of preventing heat from being transmitted downward and improving energy saving.

  In addition, since the base cushion material 400 is installed below the heater unit 300, the heat generated by the heater wire 320 is diffused in a wide range inside the base cushion material 400, so that the heating mat 100 is spread over a wide range. Heating can be achieved and a highly comfortable heating mat can be provided.

  Further, since the base cushion material 400 has an appropriate cushioning property, an appropriate cushioning property can be obtained when the user lies down or the posture is changed, and a comfortable sleeping comfort can be provided. .

  Further, by providing the closing member 430 at the outer peripheral end portion of the base cushion material 400, it is possible to suppress wasteful heat radiation to the outside of the heating mat 100, and to improve the thermal efficiency and heating rate of the heating mat 100. Therefore, it is possible to provide a heating mat 100 that is highly energy-saving and easy to use.

  Further, the connector receiving portion 632 of the connector 630 that connects the main body 200 and the controller unit 600 is provided in the vicinity of the short side of the upper surface of the main body 200, and the controller unit 600 can be installed on the short side. In the case of using any of the bedding of the futon and the bed 110, the controller unit 600 can be prevented from obstructing the user to enter and exit the bedding, and the controller 610 can be disposed at a position where it can be easily operated. The heating mat 100 with good quality can be provided.

  Further, since the binding belt 521 for fixing the controller 610 is installed in the vicinity of the connector receiving portion 632, the controller 610 is fixed at a position that becomes a bedside in the user's sleeping state, so that the controller 610 is easily operated. Can improve usability.

  In particular, when the heating mat 100 is used while being placed on the bed 110, the controller 610 can be installed without being obstructed by the headboard 112 of the bed 110, and the power cord can be hung near the headboard 112. Therefore, it is possible to minimize the controller unit 600 from hindering entering and exiting the bed 110. In addition, when the binding belt 521 is not installed, the controller 610 is likely to be used on the floor surface, and it is impossible to operate the controller in the sleeping state. This effect is particularly great.

  In the present embodiment, the substantially U-shaped closing member 430 is bonded and fixed to the outer peripheral end of the base cushion material 400. However, the shape of the closing member 430 is not limited to this. An approximate effect can be obtained even in a belt-like shape that closes only the end face of the base cushion material 400, or an L-shape that closes part of the end face and upper surface of the base cushion material 400.

  In the present embodiment, the closing member 430 is bonded and fixed to the outer peripheral end portion of the base cushion material 400. However, the present invention is not limited to this, and for example, faces the outer peripheral end portion of the base cushion material 400. By installing a blocking member made of a resin sheet on the inner surface of the cover 500, an approximate effect can be obtained.

  In the present embodiment, the heater unit 300 is configured using two blankets 310, but the material of the cloth is not limited to the blanket, and may be a cloth or non-woven fabric knitted with natural fibers or chemical fibers. Good.

  In this embodiment, the binding belt 521 provided with the hook-and-loop fastener 524 is used as the fixing means of the controller 610. However, the fixing means is not limited to this, and the hook without using the hook-and-loop fastener 524 is used. Alternatively, a configuration in which the controller 610 is fixed by a button, or a configuration in which the surface fastener 524 is directly installed on the lower surface of the controller 610 and is directly connected to the surface fastener installed on the upper surface of the cover 500 may be used.

It is a schematic diagram which shows the effect | action of a use condition.

  The second embodiment differs from the first embodiment mainly in the configuration of the cushion material. In the first embodiment, the base cushion material 400 is arranged only on the lower side of the heater unit 300. However, in the present embodiment, the sub cushion material 800 is separately arranged on the upper side of the heater unit 300. is there.

  In addition, the other structure of a heating mat is the same as that of Embodiment 1, the same structural member attaches | subjects the same code | symbol, and abbreviate | omits detailed description.

  As shown in FIGS. 13 and 14, the main body 700 of the heating mat 100 includes two cushion materials, a base cushion material 400 and a sub cushion material 800, and the sub cushion material 800 is disposed above the heater unit 300. The base cushion material 400 is disposed below the heater unit 300. Further, similarly to the first embodiment, a cover 500 that accommodates the entire laminate of the sub-cushion material 800, the heater unit 300, and the base cushion material 400 is provided.

The sub-cushion material 800 has a basic configuration substantially the same as that of the base cushion material 400 described in the first embodiment, and is a three-dimensional three-dimensional network made of polyester resin fibers. The external dimensions of the sub-cushion material 800 are 200 cm in length, 100 cm in width, and 1 cm in thickness, and the overall density of the sub-cushion material 800 is about 30 kg / _m ³ .

  The sub-cushion material 800 is a three-dimensional solid network made of polyester resin fibers having elasticity similar to the base cushion material 400, but has different characteristics.

In particular, the density of the base cushion material 400 is about 50 kg / _m ³ , whereas the density of the sub-cushion material 800 is about 30 kg / _m ³ . That is, the sub-cushion material 800 is formed with a lower proportion of resin fibers than the base cushion material 400, has a large compression ratio, and has soft characteristics. Moreover, the thickness is about 1 cm, and it is formed so as to be about 1/3 with respect to 3 cm of the base cushion material 400.

  Further, a substantially rectangular connector hole 810 is provided in a side portion near the upper end of the sub-cushion material 800, and the connector receiving portion 632 of the heater unit 300 accommodated therein is connected to the connector hole 810 of the sub-cushion material 800 and the cover. The connector plug 631 of the controller unit 600 can be connected to the connector receiving portion 632 by protruding upward through the 500 connector holes 520.

  In the state where the user lies on the main body 700, the base cushion material 400 is slightly depressed in the portion where the body is directly placed, but the sub cushion material 800 is directly placed on the body. The portion is greatly depressed downward and is almost compressed in the vertical direction. Thereby, when the user lies down or when the posture is changed, a soft cushioning property can be obtained and a comfortable sleeping comfort can be obtained.

  As shown in FIG. 15, a part of the heat generated from the heater wire 320 is transmitted to the upper surface side of the heater unit 300 and is transmitted to the user through the blanket 310, the sub-cushion material 800, and the cover 500. The heat is conducted in the horizontal direction inside the blanket 310, the sub-cushion material 800, and the cover 500, and diffuses over a wide range of the blanket 310, the sub-cushion material 800, and the cover 500 to raise the temperature.

  In particular, when the user lies down or when the posture is changed, the sub-cushion material 800 is greatly depressed, and the warmest air in the hollow portion at the center of the sub-cushion material 800 is randomly directed toward the outer periphery. The diffused and diffused warm air rises in the upper surface direction and raises the temperature around the user, so that the entire heating mat 100 is soaked, and the user can obtain a comfortable heating effect over a wide range. .

  On the other hand, as in Embodiment 1, a part of the heat is transmitted to the lower surface side of the heater unit 300 to heat the resin fibers 410 forming the base cushion material 400 and the air staying in the cavity 420. The heat transmitted to the resin fiber is conducted along the resin fiber, diffused over a wide range, and heated up, so that the temperature of the wide range of the sub-cushion material 800 is soaked. In addition, the heated air in the heated cavity 420 flows in a random direction along the cavity 420, diffuses to a wide range of the base cushion material 400, and increases the temperature, so that the wide range of the base cushion material 400 is increased. The effect of soaking is demonstrated. The soaked heat of the base cushion material 400 is mainly transmitted to the upper surface side and is transmitted to the user through the blanket 310, the sub cushion material 800 and the cover 500, and the user is soaked over a wide range. A comfortable heating effect can be obtained.

  As in the first embodiment, the base cushion material 400 is greatly depressed particularly when the user lies down or when the posture is changed, and the warmest air in the cavity 420 at the center of the base cushion material 400 However, the air diffused toward the outer peripheral portion is stopped by the blocking member 430 provided at the outer peripheral end portion, diffused in the upper surface direction to increase the temperature around the user, and the user is in a wide range. A comfortable heating effect can be obtained.

  As described above, the heating mat according to the present embodiment includes a three-dimensional three-dimensional network base cushion material 400 having a large number of cavities therein, thereby providing a heat insulating effect by air insulation. The heater unit 300 installed above 400 has a function of suppressing heat transfer downward and improving energy saving.

  Further, since the three-dimensional three-dimensional net-like base cushion material 400 and the sub-cushion material 800 having a large number of cavities therein are installed above and below the heater unit 300, the heat generated by the heater wire 320 can be reduced. By diffusing in a wide range inside the material 400 and the sub-cushion material 800, the heating mat 100 can be uniformly heated over a wide range, and the heating mat 100 having high comfort can be provided.

  Further, since the thickness of the sub cushion material 800 disposed above the heater unit 300 is made thinner than the thickness of the base cushion material 400 disposed below the heater unit 300, the heat generated by the heater unit is lowered downward. Is insulated and easily transmitted upward, and can provide a heating mat having a comfortable heating effect and energy saving.

  Moreover, by installing two pieces of the sub-cushion material 800 having a large compression ratio and a soft feeling and the base cushion material 400 having a small compression ratio and a hard feeling, it is possible to absorb a wide range of impacts and to be comfortable. Cushioning properties can be obtained.

  Further, by installing the sub-cushion material 800 having a large compression ratio and a soft feeling above the heater unit 300, the sub-cushion material 800 is deformed along the body shape of the user lying on the heating mat, thereby being soft. Cushioning and feel can be obtained.

  In addition, since the sub-cushion material 800 having a large compression ratio and easily deformable along the user's body shape is installed above the heater unit 300, the user's body and the heater unit 300 can be brought close to each other. Can get a comfortable heating effect.

  In the present embodiment, the closing member 430 is not installed at the outer peripheral end portion of the sub-cushion material 800. However, the present invention is not limited to this configuration, and the sub-cushion material 800 is closed similarly to the base cushion material 400. When the member is installed, the same effect as the base cushion material 400 described in the first embodiment can be obtained.

  As described above, since the heating mat according to the present invention can improve the usability particularly in the bed, it can be applied to other uses such as a warmer for bedding.
