JPH0632041Y2 - Cooking container detection device for electric cooker - Google Patents

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a cooking container detection device in an electric cooker such as a hot plate or an electric pan.

[Conventional technology]

In an electric cooker, a bar-shaped heater is installed in the cooker body by bending it into a predetermined shape, and a cooking container (a cooking plate in the case of a hot plate or an electric pan) is provided with a groove on the bottom that fits the heater. In some cases, a pan is placed on the cooking container in a detachable manner.

[Problems to be solved by the invention]

As described above, in the conventional electric cooker of the type in which the heater and the cooking container can be separated from each other, whether the cooking container is placed or not, or whether the cooking container is placed in the proper position. It was possible to energize with or without. For this reason, there is a risk of burns due to energization without a cooking container. Also, if the cooking container is in the opposite direction, and the heater does not match the groove on the bottom of the cooking container,
When the cooking container is not in the proper position because the cooking waste adheres to the heater and the power is turned on, the temperature does not rise due to poor contact, which causes a problem in cooking.

Therefore, the present invention aims to prevent electricity from being supplied unless the cooking container is placed in a proper position.

[Means for solving problems]

In order to solve the above problems, the present invention provides a cooking container in which a rod-shaped heater is installed in a cooker body by bending it into a predetermined shape, and a groove having a shape fitting with the heater is provided on the bottom surface. In an electric cooker that is detachably mounted on the cooker body, the cooker body is provided with a detection switch, and a lever for operating the detection switch is swingably attached,
A projecting piece is provided at one location of the cooking container, and one end of the lever is projected to a position where it engages with the projecting piece, and one end of the lever engages with the projecting piece only when the cooking container is in the proper position. In addition, the other end is configured to operate the detection switch.

〔Example〕

The electric cooker of the embodiment shown in the drawings is a hot plate, and comprises a cooker body 1, a heat shield plate 3 on which a rod-shaped heater 2 is bent and attached in a predetermined shape, and a cooking plate 4.

The cooker main body 1 has a cooking section 5 composed of a recess having a size slightly larger than that of the plate 4, and a peripheral wall of the cooking section 5 serves as a guard section 6. The cooking plate 4 is adapted to fit the heater 2 into a groove 7 provided on the lower surface thereof. Further, a protruding piece 8 protruding laterally is provided at the center of the lower end of the side surface on the short side of the cooking plate 4.

On the other hand, a mounting hole 9 is formed on the inner side surface of the cooker main body 1, and a lever 10 is inserted into the mounting hole 9 to swingably mount the cooker main body 1. The outer end of the lever 10 is the cooker body 1
Facing the detection switch 1 provided on the
The inner end of 0 protrudes inward of the cooker main body 1, that is, inward of the cooking section 5, and when the cooking plate 4 is placed in the regular position (see the chain double-dashed line in FIG. 2), Lever 1 by 8
When 0 is operated, the detection switch 11 is activated. In other words, the lever 1 engaged with the protruding piece 8 of the cooker body 1 only when the cooker body 1 is in the regular position.
The other end of 0 sets the shape of the lever 10 and its mounting position so as to activate the detection switch 11. 1 in the figure
Reference numeral 2 is a spiral spring that biases the lever 10.

In FIG. 3, an elastic detection rod 13 is attached to the inner end of the lever 10 and the tip of the detection rod 13 is brought into contact with the projecting piece 8 of the cooking plate 4. According to this structure, when the cooking plate 4 is pushed further from the regular position, the force of the force causes the detection rod 13 to bend, which prevents the detection switch 11 from being applied with an excessive load.

Although not shown, the detection switch 11 is connected to the power supply circuit in series.

[Effect of device]

As described above, in the present invention, the detection switch operates and power is supplied only when the cooking container is placed in the proper position. When the cooking container is not placed, or when the cooking container is uncertainly placed, the lever does not engage with the projecting piece, and therefore the detection switch does not operate, so that the heater is not energized. In particular, it is designed to detect whether the cooking container is in the proper position by the engagement of the lever and the protruding piece protruding from the cooking container. Also, by vertically shifting, there is no inconvenience that the heater is energized when the heater is not properly fitted in the groove on the bottom surface of the cooking container.

As in the embodiment, when one end of the lever is engaged with the protruding piece of the cooking container, heat is less likely to be transmitted to the detection switch through the lever as compared with the case where the lever is engaged directly with the cooking container. There is an advantage that reliability is improved.
