Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improved electric cooking device with improved assembly and sealing performance.

In general, for electric cooking appliances such as hot plates, in order to prevent water from entering the live parts connected to the heating element when cleaning the main body of the appliance, which has a heating element inside, the conventional method is as shown in Figure 5. The plug receiver b connected to the terminal a' of the heating element a is attached to the wall surface C' inside the protector C via the backing d, and is connected to the through hole e bored in the center of the wall surface C' and the main body side. An OIJ ring g was interposed at the joint with the heat-sensitive rod insertion part f to protect the live part.

However, if there is a difference in flatness between the two at the joint, there is a risk of water intrusion into the wall surface C' from the insertion part f.

In addition, the mounting screw h when fixing the protector C to the main body
It has various problems, such as displacement due to looseness and difficulty in assembling 0977g.

The present invention was made to solve the above problem, and it is possible to assemble by providing a protrusion integrally molded with the heat-sensitive rod insertion hole, attaching a sealing member to this protrusion, and fitting it into the through hole of the protector. To provide an electric cooking appliance which is improved in performance, has reliable sealing against a live part, and allows the appliance to be washed completely.

Hereinafter, details of the present invention will be explained with reference to FIGS. 1 to 4.

Reference numeral 1 denotes a main body formed in the shape of a rectangular dish; 2 a heating element made of a sheathed wire housed in the bottom of the main body 1; 3 a protector attached to one side of the main body 1; 4
An insulating wall surface 3' is provided to cover the heat-sensitive rod insertion section 5 integrally molded with the main body 1, and a pair of plug receivers 6 are attached to this wall surface 3' and connected to the charging section 4 and protrude outward.
, 6 is formed in the shape of a case.

Reference numeral 7 indicates a backing for the plug holder, and the plug holder 6, which is attached by penetrating both sides of the wall surface 3', is brought into close contact with the wall surface 3'.

8 is a sealing member made of an O-ring, for example, and is attached to the wall surface 3'.
The insertion portion 5 and the protector 3 are interposed between a through hole 9 bored in the center of the heat-sensitive rod insertion portion 5 and a protrusion 10 formed at the tip of the heat-sensitive rod insertion portion 5 and inserted into the through hole 9. Live part 4 from the gap
Prevents water from seeping inside.

11 is a backing made of silicone rubber or the like that keeps the space between the protector 3 and the main body 1 liquid-tight, 12 is a terminal plate attached to the plug receiver 6, 13 is a node wire, 14 is a fixing screw for the protector 3, and 15 is a A plug-in thermometer with a built-in automatic temperature controller, 16 is its heat-sensitive rod.

As described above, the protector 3 is attached to the main body 1 through the packing 11 in a liquid-tight manner around its periphery, and the heat-sensitive rod insertion portion 5
is fixed by inserting the protrusion 10 into the through hole 9 together with the sealing member 8, and also increases the contact area at the joint between the inside of the through hole 9 and the back surface of the wall surface 3'. It can be installed in a liquid-tight manner.

Therefore, even when the main body of the appliance is washed in order to remove oil stains and the like after cooking, it is possible to reliably prevent water from entering the charging section 4.

Furthermore, when fixing the protector 3, it is only necessary to fit the seal member 8 to the protrusion 10 in advance and then fit it into the through hole 9 of the wall surface 3', which simplifies assembly. Even if there is an error in the installation, it will be absorbed and will not cause any problems.

As described in detail above, the present invention includes a device main body having a live part of a heating element and a heat-sensitive rod insertion part, and a wall surface having a plug receptacle connected to the live part and a through hole facing the insertion part. The electric cooking device comprises a protector provided, a protrusion that is molded integrally with the insertion portion of the main body and fits into the through hole, and a sealing member that is attached to the protrusion to keep the charged part liquid-tight. Since it is a container, it has the excellent advantage of being able to prevent water from entering the live parts, making it possible to wash the whole body, and being easy to assemble.
