DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a controller for an electric heater, and more particularly to a controller for an electric heater having a support for the electric heater.

[0002]

2. Description of the Related Art A conventional cotter roller of an electric warming device has a structure as shown in FIGS. In FIGS. 5, 6, 7 and 8, the controller is constituted by a knob 2, an upper case 3, a lower case 4, and a support base 5, and connects the electric heater 1 to the edge of the upper case 3 and the lower case 4. The knob 2 is assembled with the support base 5 by being pinched, and the knob 2 is attached to a hole 6 formed by the upper case 3 and the support base 5 and located on the upper surface side of the flat part 7 of the support base 5. The support 5 had a right angle from the plane portion 7 to the hole 6.

[0003]

However, in the above configuration, since the support base 5 is at a right angle from the flat portion 7 to the hole 6, dust tends to accumulate on the right-angled portion and even if the user cleans the dust. Since the knob 2 is hard to be removed, the sliding of the knob 2 becomes poor and the user is unsatisfactory. If water or the like is spilled on the controller, water splashed on the flat portion 7 of the support base 5 enters the hole 6. However, there is a disadvantage that the waterproofness of the controller cannot be maintained.

The present invention solves such a conventional problem. The dust does not accumulate on the support 5 and the knob 2 can slide smoothly.
It is an object of the present invention to provide a controller of an electric warming device having high waterproofness that does not enter the housing.

[0005]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, a controller for an electric warming device according to the present invention comprises a knob, a box-shaped upper case having an opening at a lower surface, and a box-shaped upper case having an opening at an upper surface. A lower case, a support table sandwiched between edges of the upper case and the lower case, wherein the knob is provided via a hole formed by the upper case and the support table, Is provided at a position on the upper surface side of the flat part of the support base, the support base has a concave curved surface at a rising part from the flat part to the hole, and is electrically operated by the upper case and the lower casing. It is configured by sandwiching the main body of the heater.

[0006]

According to the present invention, with the above structure, the support base is
Since the flat part to the hole is formed by a curved surface that is convex downward, even if dust accumulates on the support, it can be easily cleaned, and even if water splashes on the support, water will flow from the hole. This prevents entry into the controller.

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A controller for an electric warmer according to an embodiment of the present invention will be described below with reference to FIGS.

In FIG. 1, reference numeral 1 denotes an electric heater.
The controller includes a knob 21, an upper case 3 forming an upper portion, a lower case 4 forming a lower portion, a support 51, a hole 6 formed by the upper case 3 and the support 51, and the support 51 is a flat portion 7. A concave curved surface 8 is formed in the rising portion from the hole 6 to the hole 6, and the electric warming device main body 1 is sandwiched between the upper case 3 and the lower case 4.

The hole 6 is provided at a position on the upper surface side of the flat portion 7 of the support base 51. In the above-described configuration, since the support 51 has the concave curved surface 8 formed at the rising portion from the flat portion 7 to the hole 6, even if dust is accumulated on the support 51, the support 51 can be easily cleaned along the curved surface 8. Therefore, the sliding of the knob 21 can be performed smoothly. Further, even if water or the like is spilled on the controller, even if the water is rebounded by the support base 51, the water can be prevented from entering the hole 6 by the curved surface 8, so that the waterproofness can be maintained.

[0010]

As is apparent from the above description of the embodiment, according to the controller of the electric heater of the present invention, the support base has a concave curved surface at the rising portion from the flat portion to the hole. Therefore, even if dust accumulates on the support base, it can be easily cleaned along the curved surface, so that the knob can slide smoothly. Further, even if water or the like spills on the controller, even if the water rebounds on the support, the curved surface of the support can prevent water from entering the inside of the controller through the hole, so that waterproofness can be maintained.
