Abstract

PURPOSE:To ensure the design of a controller wherein even dust accumulated on a supporter table is easily cleaned and water is prevented from entering through a hole. CONSTITUTION:There are included a knob 21, an upper casing 3 which forms an upper part, a lower casing 4 which forms a lower part, and a supporter table 51 held between edges of the upper and lower casings 3 and 4. The knob 21 is provided via a hole 6 formed with the upper casing 3 and the supporter table 51. The supporter table 51 forms a recessed surface 8 along a building-up portion extending from a flat plane part 7 to the hole 6, and an electrical heating device is held between the upper and lower casings. With the construction, any dust on the supporter table 51 is likely to be removed with ease and water is prevented from entering through the hole 6.

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

0002

2. Description of the Related Art A conventional electric heating device called a cotton roller has a structure as shown in FIGS. 5 to 8. 5, 6, 7, and 8, the controller is composed of a knob 2, an upper case 3, a lower case 4, and a support stand 5, and the electric heating device main body 1 is connected to the edge of the upper case 3 and the lower case 4. The knob 2 was assembled by being clamped together with the support base 5 at the upper part, and the knob 2 was attached to a hole 6 formed by the upper case 3 and the support base 5 and located at a position on the upper side of the flat surface part 7 of the support base 5. The support stand 5 had a right angle from the plane part 7 to the hole 6.

0003

[Problems to be Solved by the Invention] However, in the above structure, since the support base 5 has a right angle from the flat part 7 to the hole 6, dust tends to accumulate in the right angle part, even if the user cleans it. Because it is difficult to remove, the knob 2 may not slide properly, resulting in a product that is unsatisfactory to the user.Also, if water spills on the controller, the water that bounces off the flat surface 7 of the support base 5 may enter the hole 6. The disadvantage is that the controller cannot maintain its waterproof properties.

[0004] The present invention solves the problems of the prior art. Dust does not accumulate on the support base 5, the knob 2 can be smoothly slid, and the water that has bounced off the support base 5 flows through the hole 6.
The purpose of the present invention is to provide a highly waterproof controller for an electric heating device that does not get wet.

[0005]

[Means for Solving the Problems] In order to solve the above problems, a controller for an electric heating device of the present invention includes a knob, a box-shaped upper case having an opening on the lower surface, and a box-shaped upper case having an opening on the upper surface. The knob is provided through a hole formed by the upper case and the support base, and the knob is provided through a hole formed by the upper case and the support base. , the supporting stand is provided at a position on the upper surface side than the flat part of the support stand, and the support stand has a concave curved surface in a rising part from the flat part to the hole, and the upper case and the lower case provide electricity. It is constructed by sandwiching the body of the heating device.

[0006]

[Operation] According to the present invention, with the above-described configuration, the support base can
Since the area from the flat part to the hole is composed of a downwardly convex curved surface, even if dust accumulates on the support base, it can be easily cleaned, and even if water splashes off the support base, water will not flow out from the hole. This will prevent it from entering the inside of the controller.

[0007]

DESCRIPTION OF THE PREFERRED EMBODIMENTS A controller for an electric heating device according to an embodiment of the present invention will be described below with reference to FIGS. 1 to 4.

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

The hole 6 is provided at a position closer to the upper surface of the support base 51 than the flat surface 7 . In the above configuration, by forming the concave curved surface 8 on the rising part of the support base 51 from the flat part 7 to the hole 6, even if dust accumulates on the support base 51, it can be easily cleaned along the curved surface 8. This allows the knob 21 to slide smoothly. Further, even if water or the like spills on the controller and bounces off the support base 51, the curved surface 8 prevents the water from entering the hole 6, so that waterproofness can be maintained.

0010

[Effects of the Invention] As is clear from the description of the embodiments above, according to the controller of the electric heating device of the present invention, the support base forms a concave curved surface on 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, allowing the knob to slide smoothly. Furthermore, even if water or the like spills on the controller and the water bounces off the support base, the curved surface of the support base prevents the water from entering the controller through the holes, thereby maintaining waterproofness.
