Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 shows the outline of the overall structure of a portable sheet heating device (hereinafter, simply referred to as a heating device) 1.

That is, the heat generating device 1 includes a heat generating body 2 and a control device 3.

As shown in FIG. 2, the heating element 2 is formed by laminating an air layer forming material 22, a reflection film 23, and a heat insulating material 24 on the back surface of a sheet heating element 21 in which a conductive material is mixed. ing.

Of these, the sheet heating element 21 is a sheet made by mixing carbon fibers, which is a conductive substance, and processed into a sheet (Toho sheet heating element manufactured by Toho Rayon Co., Ltd., a product manufactured by Harada Sangyo Co., Ltd. Fabrypia H), carbon particles coated with and immersed in a base fabric (a sheet heating element manufactured by Kaken Co., Ltd.), and the like can be preferably used. The sheet heating element 21 is provided with a printed electrode 25 made of silver paste, copper foil, or the like in the vicinity of both sides facing each other, and from this printed electrode 25, a connector 26 for energization having excellent water resistance and waterproofness is derived. Has been done.

The air layer forming material 22 is interposed between the sheet heating element 21 and the reflection film 23 to insulate the two, and at the same time efficiently reflects the heat transmitted to the reflection film 23 side to form a sheet. This is for radiating heat to the surface side of the heating element 21. Therefore, the air layer forming material 22 is not particularly limited as long as it can form an air layer between the planar heating element 21 and the reflection film 23, and examples thereof include heat resistant resin, paper, and film. Alternatively, it is possible to use a mesh plate-like member formed by forming aluminum foil into a honeycomb shape.

The reflection film 23 is for preventing heat from the sheet heating element 21 from escaping to the back surface side, and a commonly used aluminum vapor deposition sheet or the like can be used.

The heat insulating material 24 is not particularly limited as long as it is a material having a heat insulating effect.
A non-woven fabric formed of glass wool or the like, a urethane foam formed in a sheet shape, or the like can be used.

The heating element 2 formed by stacking these is
As shown in FIG. 3, in a state where six sheets are arranged in a horizontal row, the heat-resistant resin film 20 covering the six heating elements 2 is sandwiched from both sides thereof. And each heating element 2
The entire boundary is laminated by welding or heat-sealing the boundary part and the peripheral part.

However, the connector 26 must have its insertion port exposed from the heat-resistant resin film 20 to the outside. Also, these connectors 2
6, the wiring connector 41 having the wiring 4 may be laminated. In this case, by connecting to the connector 26 that is in conduction with the heating element 2, the heating element 2 can generate heat and the wiring connector 4 that is in conduction with the wiring 4 is connected.
By connecting to 1, it is possible to prevent the heating element 2 from generating heat, and it is possible to freely connect wiring. At this time, the connector 26 and the wiring connector 41 can be distinguished from each other so that the connector 26 and the wiring connector 41 can be distinguished from each other.
It is preferable to change the color of the insertion port of and. The connection between the connector 26 and the wiring connector 41 can be performed using the connection cord 5 having the connector pins 51 at both ends.

If the connection with the connection cord 5 is not desired, the heat generating elements 2 may be preliminarily connected to each other in a wired manner and sandwiched by the heat resistant resin film 20 for lamination. In this case, the welder or heat seal at the boundary between the heating elements 2 must be avoided so as not to damage the wire connecting the heating elements 2.

The heating element 2 laminated in this way
Can be folded using the boundary portion of each heating element 2 as a fold line, and is compact and convenient for carrying. Then, when used, the control device 3 is connected to the connector 26 or the wiring connector 41 for use by standing in the state of being spread like a folding screen, encircling or laying around the user. .

The state of connection of the heating elements 2 is not limited to the one connected in a horizontal line as in this embodiment, but can be connected vertically and horizontally. Further, the number of the heating elements 2 is not particularly limited to 6, and the required number of the heating elements 2 can be used within the power consumption.

When the heating element 2 is used in an upright state, as shown in FIG. 4, a pedestal 6 having an insertion portion 61 adapted to support the entire bottom surface of the heating element 2, or a drawing As shown in FIG. 5, if a pedestal 6 having an insertion portion 61 configured to support a part of the bottom surface of the heating element 2 is used, it can be stood in a stable state.

The control device 3 is constructed by providing a control box 30 between an energizing connector 31 for connecting to the connector 26 and the wiring connector 41 provided on the heating element 2 and a household 100V outlet plug 32. Has been done. Then, the on / off switch 33 and the temperature control knob 34 provided in the control box 30 are used to turn on / off the heat generator 2 and adjust the temperature. In addition, when the heating element 2 is used around water such as a bathroom, 24 V of 100 V, for example, is put in the control box 30.
By incorporating a voltage converter for stepping down to V, a current amplifier, or the like, the control device 3 for preventing electric shock can be provided. Alternatively, the control device 3 may be incorporated in any one of the heating elements 2, and only the outlet plug 32 may be led out from the heating element 2.

The heating device 1 constructed in this way is
In the home, for example, when used in the bathroom, the bathroom can be used as a sauna bath, or can be placed in the living room, at the entrance, under a desk, or the like for heating.

In the fields of agriculture and animal husbandry, it can be used, for example, as a heat source for heating vinyl greenhouses, a hotbed in hydroponics, or for heating livestock sheds.

In this embodiment, the heating elements 2 are connected to each other, but as shown in FIG. 6, the heating elements 2 are individually laminated by the heat-resistant resin film 20 to form the peripheral portion. The connection means 7 may be provided with a magic tape (trademark of Nippon Velcro Co., Ltd.). In this case, the heating element 2 provided only with the loop tape 71 and the heating element 2 provided only with the hook tape 72 on the peripheral portion may be prepared, and both may be connected (see FIG. 6 (a)). ) Alternatively, only the loop tape 71 may be provided on the peripheral portions of all the heating elements 2, and the hook tapes 72 separately prepared may be connected to each other (FIG. 6 (b)).
reference). As a result, the degree of freedom in combining the heating elements 2 is further expanded, and it is possible to create the heating element 2 freely based on the idea of the user. For example, a pentagonal heating element 2 and a hexagonal heating element 2 can be formed into a soccer ball shape, or a three-dimensional structure can be freely configured by combining other heating elements 2.

The connecting means 7 is not limited to the magic tape (trade name of Nippon Velcro Co., Ltd.), but may be a fastener or an adhesive tape.

Further, since the heating element 2 is heated by far infrared rays, not the heating element 2 but a structure which is only required for internal reflection is arbitrarily connected depending on a user's intention or a necessary ambient (sensation) temperature. It is also possible. In other words, it is possible to use a plate-shaped body (not shown) that is substantially the same as the heating element 2 with the reflection film 23 or the reflector (not shown) attached to the outer surface thereof and the connecting means 7 provided at the peripheral edge.
