Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to furniture with a heater that incorporates a cooking surface made of heat-resistant material flush with the cooking surface, and detects when a heated cooking pot is placed offset from the cooking surface. The purpose is to issue a warning.

Generally, the surface of the so-called top of furniture such as a seating table is finished with melamine resin or the like. This is to improve the appearance of the furniture and improve its appearance. For example, a cooking table is constructed by incorporating a heating device into such a top plate, but with the spread of electromagnetic induction heaters, a cooking surface made of highly heat-resistant ceramic material is incorporated on the same plane as the top plate, making it easier to clean. Provides user-friendly furniture. In this case, the cooking surface is flush with the top plate, giving it an excellent appearance.
Also, while it has the advantage of fully functioning as a regular table when the heater is not in use, if the cooking pot is placed off the cooking surface, a relatively low heat-resistant top plate such as melamine resin can be used. It has the disadvantage of burning.

The present invention deals with this situation, and embodiments thereof will be described below with reference to the drawings. The embodiment relates to a furniture top plate in which an electromagnetic induction heater (not shown) is incorporated; 1 is a top plate made of wood, for example;
The surface is coated with a melamine resin film, etc., and has relatively low heat resistance. Reference numeral 2 denotes a cooking surface of the electromagnetic induction heater, which is installed on the same plane as the top plate 1 with a heat insulating material 3 in between, and is made of a heat-resistant material such as ceramic. Top plate 1 close to the periphery of cooking surface 2
A thermally responsive body 4 is buried in the thermally responsive device 4, and a switch for an alarm device is provided in correspondence with this thermally responsive device 4.

Details of the thermal response device 4 are as shown in FIGS. 3 and 4. Reference numeral 5 denotes an outer case made of stainless steel, the upper surface of which is exposed flush with the upper surface of the top plate 1. 6 is a dish-shaped bimetal, and 7 is a pushing member located at the bottom of the bimetal 6, which is movable up and down. Reference numeral 8 denotes a switch located at the lower part of the pushing member 7, which has an operating piece 9 that is biased upward, and is of a normally closed type.

A plurality of pairs of thermal response devices 4 and switches 8 are provided around the periphery of the cooking surface 2, and each switch 8 is connected in parallel to the circuit of an alarm device such as a buzzer, and when one of the switches is turned on, the alarm device is activated. make it work.

FIG. 3 shows a state in which there is no pot above the thermal response device 4, the bimetal 6 is not deformed, the operating piece 9 is pushed through the pushing member 7, and the switch 8 is opened. FIG. 4 shows a case where the cooking pot 10 is placed on the top plate 1 and is being heated. The switch 8 closes and closes the alarm circuit to issue an alarm.

In addition to the sound of a buzzer, the warning device can also include the lighting of a warning light. In addition, insulation material 3
The vertical length of the plate member constituting the cooking surface 2 is larger than the thickness thereof. This is to prevent the heat of the pot from acting on the thermally responsive body 4 and causing it to malfunction when the cooking pot 10 is normally placed on the cooking surface 2.

As described above, according to the present invention, when the cooking pot 10 is placed deviated from the cooking surface 2 as shown in FIG. 1, the alarm device is activated to notify abnormal use. It is possible to prevent accidents such as scorching the surface of the top plate when placed on the board 1, and the practicality of this type of so-called smooth-top furniture with a heater can be greatly improved.
In addition, since the device detects when the pot is being heated and does not issue an alarm when the pot is not heated, it is more practical as it eliminates the inconvenience of emitting an alarm sound unnecessarily.
