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.

This type of conventional electric cooker has a sheathed heater cast into the bottom, or has a grill plate or pot attached to it that is fixed to a frame or body made of heat-resistant plastic or the like. However, when cleaning grill plates and pots 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 are removably attached to the frame or body.

However, with this cooker, if you turn on the electricity with the grilling plate or pot removed from the frame or body, that is, if you turn on the electricity with the grilling plate or pot placed directly on the table, etc., the grilling plate or pot will heat up. There were drawbacks such as burning the table and causing a fire.

This idea was developed in view of the issue of slanting, and its purpose is that when the main body of the cooking device, such as a grill plate or pot, is removed from the exterior body such as the frame or body, the main body of the cooking device To provide an electric cooker which cannot be energized.

Next, one embodiment of this invention will be described with reference to the drawings.

Reference numeral 1 denotes a main body of a cooking device such as a grill plate or a pot (the figure shows the grill plate), and a sheathed heater 11 is fixed to the back side by means such as welding.

The tip of this heater 11 is attached to a heater terminal 12 fixed to the back surface of the main body 1.

That is, the tip of the heater 11 is connected to the L-shaped terminal board 1.
It is fitted and fixed in the hole 12a1 of 2a.

In addition, a notched bent piece 12 is provided in the center of the terminal board 12a.
A2 is formed, and a movable plate 12b made of a magnetic material and having a U-shaped side surface is rotatably attached by a pin 12C using this bent piece 12a2 and the lower surface of the terminal board 12a.

Furthermore, a heat-sensitive pipe 13 into which a heat-sensitive rod 31 of a plug 3 with a temperature controller to be described later is inserted is fixed to the lower surface of the main body 1 by means such as welding.

Note that short terminals 11b are attached to the tip of the heater 11ρ via a heater backing 11a (the spacing between the terminals 11b is set to be the same as the terminal holes of the temperature controller plug 3, which will be described later). ).

Reference numeral 2 denotes an exterior body such as a frame or a body (the frame is shown in the figure) on which the cooking device main body 1 is placed and fixed, and the main body 1 can be easily attached and removed.

This exterior body 2 includes a plug 3 with a temperature controller, which will be described later.
A through hole 21 a into which the heat-sensitive rod 31 is inserted, and a terminal pin 21 into which the terminal hole of the temperature controller plug 3 is inserted.
b is provided.

Note that when the cooking device main body 1 is set in the exterior body 2, it is positioned so that the heat-sensitive pipe 15 and the through hole 21a coincide with each other.

Further, a notch 22 is formed in the exterior body 2, and a heater terminal receiver 2 is connected to the heater terminal 12 here.
3 is attached by screws 24.

This terminal receiver 23 is a magnetic catch 23b fixed to the center of a cover 238 made of an insulating material such as synthetic resin.
(sandwich structure of one magnet with two yokes), a spring holding plate 23C fitted in grooves 23a1 formed on both sides of the spring holding plate 23C, and a spring holding plate 23C fitted in grooves 23a1 on both sides thereof; It is composed of a movable terminal 23d fitted into a spring holding plate 23C, and a spring 23e stretched between a disk 23d1 of the movable terminal 23d and the spring holding plate 23C.

And the base end of the movable terminal 23d and the terminal pin 2
1b through a lead wire 25.

3 is a plug with a temperature controller that is inserted into the recess 21 of the exterior body 2, and a heat-sensitive rod 31 is inserted into the through hole 21a, and a terminal pin 21b is inserted into a terminal hole (not shown).

Note that 32 is a temperature control knob, and 33 is a power cord.

Next, to explain the usage condition based on the above-described structure, when the cooking device main body 1 is now housed in the exterior body 2, the heat-sensitive pipe 13
matches the through hole 21a, and the heater terminal 12
corresponds to the heater terminal receiver 23.

At this time, the terminal 11b of the heater terminal 12 corresponds to the movable terminal 23d of the heater terminal receiver 23, and the two elastically come into contact with each other due to the spring force of the spring 23e.
electrically connected.

Furthermore, the magnetic catch 23b corresponds to the movable plate 12b, and both are attracted by the magnetic force of the magnet.
The heater terminal 12 and the heater terminal receiver 23 are also mechanically coupled, and the terminal 11b and the movable terminal 23d are not easily separated.

Furthermore, since the movable plate 12b is rotatable by the pin 12C, even if the cooker main body 1 is stored at an angle with respect to the exterior body 2, the magnetic catch can be secured by rotating the movable plate 12b. The suction with the movable terminal 23b is reliably performed, and therefore the contact between the terminal 11b and the movable terminal 23d is reliably performed.

Then, insert the plug 3 with a temperature controller into the recess 2 of the exterior body 2.
1, the heat-sensitive rod 31 is inserted into the heat-sensitive pipe 13 through the through hole 21a, and the terminal pin 21
Since the movable terminal 23d is inserted into the terminal hole, the movable terminal 23d is energized via the lead wire 25, and therefore the sheathed heater 11 is energized via the terminal 11b, so that the cooking device main body 1 is heated.

When the cooking device main body 1 reaches a temperature predetermined by the temperature adjustment knob 32, the heat-sensitive rod 31 detects this and the power supply from the temperature controller 3 is cut off.

Next, with the cooker body 1 removed from the exterior body 2,
Even if an attempt is made to energize the cooking device main body 1, the tip of the heat-sensitive rod 31 hits the movable plate 12b of the heater terminal 12 and cannot be inserted, so the terminal 11b may not be inserted into the terminal hole of the plug 3 with temperature controller. Therefore, the cooking device main body 1 is not energized and is not heated.

In the above embodiment, the movable terminal 23d utilizing spring force is used as the heater terminal receiver 23, but this may be freely replaced with a known appropriate connection terminal.

If the connection with the terminal 11b is ensured, the magnetic catch 23b is not necessary.

Further, in the above embodiment, the temperature of the cooker main body 1 is adjusted by the plug 3 with a temperature controller, but the plug 3 with a temperature controller may be a simple plug,
Attach a temperature regulator such as a thermostat or infinite switch to the cooking device main body 1 or the exterior body 2, and
It is also possible to heat it to a desired temperature.

As mentioned above, this idea made the plug connection part of the temperature controller etc. and the connection part between the cooker body and the exterior body separate from the above connection part, and also made it impossible to connect the cooker body and the plug. As a result, it is not possible to energize the cooker unless it is attached to the exterior body, and even if the cooker body and the exterior body can be separated, it is possible to accidentally energize only the cooker body. It has the advantage of being able to be used safely.
