Description

[Detailed description of the invention] [Technical field of the invention] The present invention relates to an electric heating device whose main body is in the form of a sheet, such as an electric carpet, and in particular, a control box having a switch for controlling the heater, etc. is attached to the main body. The present invention relates to an electric heating device configured to be detachably connected.

[Technical background of the present invention and its problems]

For electric heating devices such as electric carpets,
A control box having a switch for controlling the heater, etc. is provided on a rectangular sheet-like main body having a heater, and a cover is placed on the top surface of the main body. Conventionally, this control box has been installed in two ways: a connector is attached to the main body, and a control box separate from the main body is removably connected to the connector via a connecting cord; There is also one in which the control box is directly attached to the main body.

However, in the case of the former of the above conventional methods, not only is the cost high as a multi-core connection cord is required between the main body and the control box, but such a multi-core connection cord has relatively high rigidity. Therefore, this connection cord and the control box located at the tip of it tend to get in the way of walking, etc., and as mentioned above, the connection cord has high rigidity, so the control box has no choice but to separate from the main body. There is a problem in that it is difficult for older users to operate the control box. On the other hand, in the case of the latter, although there are advantages such as cost reduction as multi-conductor connection cords are not required and ease of operation of the control box, this is difficult because the relatively large control box is integrated with the main body. In addition to the problem that the control box gets in the way, the cover that hangs over the main body must be shaped in a special way to prevent the cover from covering the control box. There is a problem in that the cost is high.

[Purpose of invention]

The present invention was developed in consideration of the above circumstances, and its purpose is to make it possible to easily operate the control box from the top of the main body, to prevent the control box from getting in the way as much as possible, and to prevent the control box from getting in the way of the main body. There is no need to make a special shape for the cover that is hung on top.
To provide an electric heating device which can eliminate the need for a multi-core connection cord, and at the same time can reduce costs.

[Summary of the idea]

In the present invention, a connector is provided on the peripheral edge of a sheet-like main body having a heater so as to be located within the area of the main body, and a control box having a switch for controlling the heater, etc. is provided on the main body with respect to the connector. The control box is provided so as to be detachably connected from the side, and a stopper convex portion is provided on the upper surface of the control box and faces the edge of the cover that is hung on the surface of the main body. The knob for the stopper is located on the opposite side. Therefore,
The control box is attached to and detached from the main body without using a connection cord, and the control box is located outside the area of the main body when the control box is attached to the main body, and the cover to be hung on the main body is attached to the control box. The feature is that it does not get caught in the switch etc.

[Example of idea]

An embodiment in which the present invention is applied to an electric carpet will be described below with reference to FIGS. 1 and 2.

1 is a rectangular sheet-like main body with a heater 2 inside.
are laid out in a meandering pattern. Reference numeral 3 denotes a flat rectangular connector, which is attached to the periphery of the main body 1, in this case at one corner, so as to be located within the area of the main body 1, and has an insertion opening 4 for connection on one side. It is formed. Reference numeral 5 designates a control box which also has a flat rectangular shape. Although not shown inside, a switch for controlling the heater 2, a power switch, etc. are provided, and a knob 6 for controlling the heater 2 and a knob 7 for the power switch are provided on the top surface. is provided to protrude from the top surface. Further, a connecting piece 8 corresponding to the insertion port 4 of the connector 3 is protruded from one side of the control box 5.
A power cord 9 having a plug 9a is led out from the side adjacent to this. The control box 5 is detachably connected to the connector 3 from the side of the main body 1, and is attached to the main body 1 when the connecting piece 8 is inserted into the insertion opening 4 of the connector 3.
It has a protruding shape on the outside. Reference numeral 10 denotes a cover placed over the main body 1, which has approximately the same shape as the main body 1 and is slightly larger than the main body 1, so as not to cover the knobs 6 and 7 of the control box 5. It is composed of

Moreover, a stopper convex portion 11 is integrally provided on the upper surface of the control box 5 and faces the edge of the cover 10 that is hung on the upper surface of the main body 1. Furthermore, the knobs 6 and 7 are disposed on the upper surface of the control box 5 on the opposite side of the cover 10 with the stopper convex portion 11 as a boundary. Furthermore, the protruding heights of these knobs 6 and 7 are made lower than the stopper convex portion 11.

According to the above configuration, the connector 3 is provided at the peripheral edge of the main body 1 so as to be located within the area of the main body 1, and the control box 5 is detachably connected to the connector 3 from the side of the main body 1. As a result, the control box 5 is placed adjacent to the main body 1, and the user sitting on the main body 1 can easily operate the control box 5. In addition, in this case, since there is no connecting cord with high rigidity between the main body 1 and the control box 5, the connecting cord and the control box do not get in the way of walking etc. as in the conventional case. The cost can be reduced by eliminating the need for multi-core connection cords. Furthermore, according to this embodiment, since the control box 5 exists outside the area of the main body 1, the control box 5 does not get in the way of the user on the main body 1, unlike the case where the control box exists within the area of the main body. In addition, the cover 10 hung over the main body 1 is attached to the main body 1 regardless of the control box 5 part.
The cover 10 may have a shape that covers the entire area, and therefore, the cover 10 can be specially shaped so that the control box 5 portion is cut out, and the cost can be reduced accordingly.

Incidentally, the present invention is not limited to the above embodiment, and the connector 3 may be provided on the side edge of the main body 1, for example, as shown in a different embodiment in FIG.

[Effect of idea]

As is clear from the above description, the present invention provides a connector on the periphery of a sheet-like main body having a heater so as to be located within the area of the main body, and a controller having a switch for controlling the heater, etc. Since the box is configured to be detachably connected to the connector from the side of the main body, the control box can be easily operated from above the main body, and the control box can be prevented from getting in the way as much as possible. Moreover, the cover to be hung over the main body does not need to have a special shape, and a multi-conductor connection cord can be eliminated, which together with the fact that costs can be reduced. Furthermore, a stopper protrusion is provided on the top surface of the control box that faces the edge of the cover that is hung on the top surface of the main body, and switch knobs and the like are located on the opposite side of the cover with this protrusion as a boundary. Even if the cover shifts over the main body and covers the control box, further movement of the cover can be restricted by the edge of the cover coming into contact with the stopper protrusion. Therefore, the shifting cover can be prevented from covering the switch knob, etc., so the control box can be easily operated without the cover making it difficult to operate the control box.
