Description

[Detailed description of the invention] This invention relates to an electric cooking device such as a griddle or a pot equipped with a heater.

Conventionally, this type of electric cooker has a sheathed heater cast into the bottom or a welded grill plate or pot fixed to a frame or body made of heat-resistant plastic or the like. When cleaning after cooking, the frame and body can get in the way, and water can accumulate inside, causing problems with insulation, so washing with water is usually prohibited.

Therefore, recently, in order to make it easier to wash the grill plates and pots with water, devices have been developed in which the grill plates and pots can be attached to and detached from the frame or body.

However, with this cooker, if you remove the grill plate or pot from the frame or body, for example, if you place the grill plate or pot directly on a table, etc., and then turn on the electricity, the grill plate or pot will heat up. There were drawbacks such as burning the table and causing a fire.

The present invention was devised in order to solve these problems in the prior art, and its purpose is to connect the electrical connector to the cooker without setting the cooker main body in the exterior body. To provide an electric cooker in which electricity is not applied even when connected to a main body, and to easily, quickly and appropriately engage and disengage a terminal pin of the cooker main body and an electrical connection relay part of the exterior body. Furthermore, when the cooking device main body is set in the exterior body and the terminal pin is engaged with the electrical connection relay part, that part is completely covered to prevent it from coming off, thereby ensuring safety. Moreover, when the main body of the cooking device is not set, an electric connector is inserted directly into the main body of the cooking device so that no electricity is applied.

Hereinafter, the present invention will be sequentially explained according to an illustrative embodiment.

Reference numeral A denotes an electric cooking device, which is composed of a cooking device main body 1, an exterior body 2, and an electrical connector 3.

The cooking device main body 1 has a heater 4 attached to its lower surface and a pair of terminal pins 5, 5 at its tips, and a heat-sensitive pipe 6 in the center of these terminal pins 5, 5.
is installed.

The exterior body 2 is provided with an electrical connection relay portion 7 at a portion where the cooking device main body 1 is set and the terminal pins 5, 5 and the heat-sensitive pipe 6 are located.

The electrical connection relay part 7 is located from the plug force bar sliding part 9 of the plug force bar fixing part 8.

The plug force bar fixing part 8 has a relay terminal 1 projecting outward.
A rising piece 11 for fixing the terminal 10.10 is provided, and a pin receiver 12.12 for receiving the terminal pins 5, 5 is provided at a position away from the axis of the terminal 10.10 on the plane. A conductor 13 is provided to connect the relay terminal 12.12 and the relay terminal 10.10.

The pin receivers 12.12 are made of an elastic body so as to receive and clamp the terminal pins 5, 5 from above, and to forcibly pull them upward.

The plug bar sliding portion 9 has a stepped portion and an upper step 9a thereof.
x faces outward, while its lower stage 9a2 faces inward, and is normally biased outward by the spring 18.

The lower stage 9a2 is provided with the terminal pins 12, 1.
Through-holes 14, 14 into which the heat-sensitive pipe 6 is inserted, and a through-hole 19 into which the heat-sensitive pipe 6 is inserted are formed at corresponding positions, and under normal conditions, the pin receivers 12.
12 are each present.

When the electric connector 3 described later is inserted, the sliding portion 9 slides inward against the bias of the spring 18, and the vertical stepped portion 9a
The lower end of 3 is positioned above and inward of the pin receivers 12 and 12 that engage the terminal pins 5, 5.

The electrical connector 3 has the above-mentioned relay terminal 10.1 on its end surface 3a.
A terminal hole 15.15 that fits into the terminal hole 15.15 is opened, and a heat-sensitive rod 16 protrudes from the center thereof, and a projection 17 that abuts against the edge 9b of the sliding portion 9 is provided on its upper surface 3b. .

Next, the main functions of the electric cooking device A configured as described above will be explained separately when the cooking device main body 1 is set to the exterior body 2 and when it is not set.

■ Set 1: Set the cooking device main body 1 at a predetermined position on the exterior body 2 where the electrical connector 3 is not inserted.

At this time, the terminal pins 5, 5 of the cooking device main body 1 fall through the through holes 14, 14 and are fitted into the pin receivers 12, 12.

Next, the plug force bar fixing part 8 and the plug force bar sliding part 9
When the electric connector 3 is inserted from the outside between the heat-sensitive rods 1
6 is inserted into the heat-sensitive pipe 6, and the relay terminal 10.1
0 is inserted into the terminal hole 15.15, the protrusion 17 presses the edge 9b of the sliding portion 9 against the bias of the spring 18, and finally, as shown in FIG. At this time, the vertical step portion 9a3 is located above and inward of the pin receiver 12.12 and remains stationary.

■ When not set When the electrical connector 3 is pulled out from between the plug force bar fixing part 8 and the plug force bar sliding part 9, the sliding part 9 slides outward under the bias of the spring 18 and closes in the through hole 14. , 14, the pin receivers 12, 12 face inside.

Then, when you pull up the cooker body 1, the terminal pin 5
, 5 are pulled out from the pin receivers 12, 12 and guided outward through the through holes 14, 14.

In this way, even if an attempt is made to insert the electrical connector 3 into the cooking device main body 1 which is not set, the distance between the terminal pins 5 and 5 is larger than the distance between the terminal holes 15 and 15, so they fit together and do not conduct electricity. There's nothing to do.

As described above, according to the present invention, the danger when setting the cooker body is prevented, and electricity is not directly applied to the cooker body itself after the set is released.
This has the effect of being able to prevent accidents such as fires due to electrical leakage and incorrect use.
