Description

[Detailed description of the invention] [Industrial application field] In an electric cooker such as a hot plate, a heater (heating element) is disposed on the bottom of the cooking body in order to heat the cooking body, and a terminal for power supply to the heater is disposed on the bottom of the cooking body. is fixed to the periphery of the cooking body. The present invention relates to a fixing structure of a terminal cover to which a terminal of an electric cooking device is attached.

[Conventional technology]

Generally, the terminal cover is made of heat-resistant synthetic resin material in the shape of a rectangular tube, and a part of the top wall is omitted to make this part an open part, and this open part is fixed facing the bottom of the peripheral part of the cooking unit. ing. Since such a terminal cover inevitably comes into contact with hands and fingers when attaching or detaching the temperature controller, it is dangerous if heated to high temperatures. Therefore, in order to prevent the terminal cover from being heated to a high temperature, conventionally, as shown in FIG.
In other words, a spacer metal fitting B, which is formed by bending a metal plate to form irregularities, is secured with screws, and a terminal cover D made of synthetic resin is secured to this spacer metal fitting B with screws E.

[The problem that the idea attempts to solve]

In the conventional structure, the process for fixing the terminal cover requires a process of fixing with screws C and a process of fixing with screws E. Additionally, when attaching the terminal cover to the cooking unit, there are two joint screws: the cooking unit and the spacer metal fitting, and the spacer metal fitting and the terminal cover, so there is a drawback in terms of strength that there is a high possibility of it rattling or coming off. It was hot.

In view of the above drawbacks, the present invention simplifies the assembly process and has the effect of preventing the terminal cover from being heated to a high temperature, while allowing installation equivalent to directly screwing the terminal cover to the cooking unit. This invention has devised a terminal cover fixing structure for an electric cooker that can provide strength.

[Means to solve the problem]

A spacer metal fitting 9 in the form of a flat plate, which is formed by bending a metal plate to form unevenness, is arranged inside the terminal cover 3 in the open part by omitting a part of the top wall, and the both sides of the spacer metal fitting 9 are placed on both sides of the terminal cover. The terminal cover 3 and the cooking body 1 are fastened with screws 8 through spacer fittings 9. At this time, the spacer metal fitting 9
One of the top and bottom surfaces of the unevenness is in contact with a part of the cooking body and the other is in contact with the inner surface of the terminal cover, that is, the spacer fitting is sandwiched in a sandwich-like manner, and the cooking body and the terminal cover do not come into direct contact. shall be taken as a thing.

[Effect]

The cooking body 1 and the terminal cover 3 are firmly fixed with screws 8. At this time, the cooking body 1 and the terminal cover 3 do not come into direct contact with each other, but come into contact with each other via the spacer metal fitting 9 having an uneven surface. Therefore,
Although the terminal cover 3 is directly fixed to the cooking body by screws 8, the heat of the cooking body heated to high temperature is transmitted to the spacer metal fitting from one of the uneven surfaces of the spacer metal fitting, and the spacer metal fitting is fixed. When this happens, the heat will be transferred from the other side of the spacer metal fitting to the terminal cover. Therefore, only a small amount of heat is transmitted to the terminal cover, and the entire terminal cover is not heated to a high temperature.

〔Example〕

Hereinafter, an embodiment of the terminal cover fixing structure in the electric cooking device of the present invention will be described based on the attached drawings in which it is applied to a hot plate.

As shown in FIG. 1, the hot plate has legs 2 fixed to a cooking body 1 that is heated to a high temperature, and a rectangular tube-shaped terminal cover 3 is attached around the periphery so that a part of the hot plate protrudes from the periphery of the cooking body 1. Fixed to the bottom of the part.
As shown in FIG. 3, the rectangular cylindrical terminal cover 3 has a part of the top wall, i.e., the top wall at the front part, omitted to make this part an open part 3b, and the open part 3b is the peripheral part of the cooking body 1. Fix it facing the bottom. A temperature regulator 4, which is a power source for heating means for the cooking object, is detachably attached to the terminal cover 3.

As can be seen from FIGS. 2 and 5, a temperature-sensitive pipe 5 and a pedestal 6 are brazed to the bottom of the periphery of the cooking body 1, so that the terminal cover 3 can be secured to the pedestal 6 with screws 8. It is set as. That is, the temperature-sensitive pipe 5 and the pedestal 6 brazed to the cooking body 1 form a part of the cooking body, so to speak, and are heated to the same high temperature as the cooking body. The positional relationship between the pedestal 6 and the temperature-sensing pipe 5 is such that when the terminal cover is fixed to the pedestal 6, one end of the thermo-sensing pipe is located inside the terminal cover 3 together with the terminal of the heating element (not shown), and temperature control is performed. It is assumed that when the device 4 is inserted, the sensor 7 is inserted into the temperature-sensitive pipe 5 at the same time as the terminal is connected.

When fixing the terminal cover 3 to the pedestal 6, which is a part of the cooking body, with the screws 8, engage both sides of the spacer metal fittings with both sides of the inside of the terminal cover 3, and in this state, pass the spacer metal fittings through. Fasten the terminal cover 3 and cooking body 1 with screws 8. At this time, one of the uneven surfaces of the spacer metal fitting 9 is in contact with the surface of the base 6, and the other is in contact with the inner surface of the terminal cover, so that the cooking body 1 or the base 6, which is a part of the cooking body, and the terminal cover 3 do not touch. Make it. The spacer fitting 9 is made by bending a metal plate, but in the illustrated embodiment, it has two protrusions 9a, 9 as shown in FIG.
A through hole 10 for ventilation and a screw hole 11 through which a screw passes are bored. Further, screw holes 12, 12 are formed in the terminal cover 3 so that the screw hole 11 of the spacer metal fitting 9 and the screw hole 12 formed in the terminal cover 3 are aligned vertically. Reference numeral 13 denotes a ventilation hole formed in the terminal cover 3.

In order to engage the spacer fitting 9 inside the terminal cover 3, a guide groove 14 is formed on the inner surface of the side wall 3a of the terminal cover 3 as shown in FIGS. 3 and 4, and the spacer fitting 9 is inserted along the guide groove. Insert the metal fittings so that they can be held in place. Of course, it is not necessary that the spacer metal fittings do not move accidentally, but it is preferable to at least engage them so that they do not fall off during screw fastening work.

[Effect of idea]

According to the terminal cover fixing structure of the electric cooker of the present invention, the spacer fitting and the terminal cover can be fixed to a part of the cooking body at the same time with one screw, unlike the conventional method in which they are fixed separately with screws. The manufacturing process can be simplified compared to .

In addition, with conventional models, if either the screws that secure the spacer metal fittings or the screws that secure the terminal cover come loose, the terminal cover will become loose. According to the invention, the spacer metal fittings and the terminal cover are
Since the terminal cover is fixed with a common screw, the possibility of the terminal cover falling off or rattling can be reduced.
