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.

Conventional electric cookers of this kind have a sheathed heater cast or welded into the bottom of the grill plate or pot, which is fixed to a frame or body made of heat-resistant plastic or the like. 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 inspired in view of the diagonal point, and its first
The object of the present invention is to provide an electric cooking appliance in which electricity cannot be applied to the cooking appliance body when the cooking appliance body, such as a grill plate or a pot, is removed from an exterior body such as a frame or a body.

The second purpose of this invention is to provide an electric cooker in which when the cooker main body is attached to the exterior body, the two are fixed by the magnetic force of the magnet, and the electrical connection between the two is ensured. There is something to do.

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.
2a is fitted and fixed in the hole 12a1.

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 new music piece 12a2 and the lower surface of the terminal board 12a.

Furthermore, on the bottom surface of the main body 1, a temperature controller 3 (described later) is provided.
A heat-sensitive pipe 13 into which a heat-sensitive rod 31 is inserted is fixed by means such as welding.

Note that a short terminal 11b is attached to the tip of the heater 11 via a heater backing 11a.

Reference numeral 2 denotes a frame body on which the cooking device main body 1 described above is placed and fixed, a protector for the body, etc. (the figure shows the frame body), and the main body 1 can be easily attached and removed.

This exterior body 2 has four parts 21 into which the tip of a temperature controller 3 (described later) is inserted, a through hole 21a into which a heat-sensitive rod 31 is inserted, and a terminal hole of the temperature controller 1-roller 3 which is fitted into a through hole 21a. A terminal pin 21b 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 screw 1-catch 2 fixed in the center of a cover 23H made of an insulating material such as synthetic resin.
3b (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 the same groove 23a1. A movable terminal 23d whose base end is inserted into the holding plate 23c with a base end of 7<
1 and the spring holding plate 23 c
It is composed of e.

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

. 3 is a temperature controller I/roller inserted into the recess 21 of the exterior body 2, and the heat-sensitive rod 31 is inserted into the through hole 21a.
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, and are electrically connected.

Further, the magnetic catch 23b corresponds to the movable plate 12b, and the two are attracted by the magnetic force of the magnet, and the heater terminal 12 and the heater terminal receiver 23 are mechanically coupled, and the terminal 11b and the movable terminal 23d are easily connected. It will not be separated.

In addition, 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 removed 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.

When the temperature controller 3 is inserted into the four parts 21 of the exterior body 2, the heat-sensitive rod 31 is inserted into the heat-sensitive pipe 13 through the through hole 21a, and the terminal pin 21b is inserted into the terminal hole. Electricity is applied to the movable terminal 23d via the wire 25, and therefore to the sheathed heater 11 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 you try to energize the cooking device main body 1, the tip of the heat-sensitive rod 31 hits the heater terminal 12 and cannot be inserted.
The terminal 11b is not inserted into the terminal hole of the temperature controller 3, so that the cooking device main body 1 is not energized and is not heated.

Further, in the above embodiment, the temperature of the cooker body 1 is adjusted by the temperature controller 3, but the temperature controller 3 may be a simple plug, and a thermostat or an input device may be installed on the cooker body 1 or exterior body 2 side. It is also possible to attach a temperature regulator such as a neat switch to heat the cooking device main body 1 to a desired temperature.

As mentioned above, this invention separates the plug connection part of the temperature controller etc. and the connection part between the cooker main body and the exterior body from the above connection part, and makes the connection between the cooker main body and the plug unnecessary. By making this possible, electricity cannot be applied to the cooker unless it is attached to the exterior body.
Therefore, even if the cooker body and the exterior body can be separated, it will not be possible to accidentally energize only the cooker body, making it possible to use the cooker safely.In addition, a magnet can be attached to the connection between the exterior body and the cooker body. By providing a catch and attaching a magnetic material to the connection part of the cooker main body, electrical connection can be made reliably at both connections, and the plug can be easily removed, thereby preventing sparks due to poor contact or discontinuity between terminals. It has the effect of being able to prevent the occurrence of such problems.
