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 is capable of electrically detecting when a cooking pot is placed out of alignment with 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. User-friendly furniture is becoming available. In this case, the cooking surface is flush with the top plate, which gives it an excellent appearance, and it functions well as a normal table when the heater is not in use. If placed off-center,
It has the disadvantage of burning the top plate, which has relatively low heat resistance, such as melamine resin.

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 and is made of a heat-resistant material such as ceramic. cooking surface 2
An operating body 3 for driving an alarm device and a switch 4 facing the operating body 3 are provided on the lower surface of the top plate 1 close to the periphery thereof. A plurality of the operating bodies 3 and switches 4 forming the pair are provided around the periphery of the cooking surface 2, and each switch 4
are connected in parallel in the circuit of an alarm device such as a buzzer,
The alarm device is activated by turning on one of the switches. The relationship between the operating body 3 and the switch 4 is shown in Figure 3.
As shown in Figure 4. Operation body 3 is case 5
and an operating rod 7 which is movable up and down within a case 5 and has a magnet 6 attached thereto, and a switch 4, for example a micro switch, is provided opposite the operating rod 7. FIG. 3 shows a state in which the operating body 3 is in a lowered position due to its own weight, and the switch 4 is pushed to open the alarm circuit. Figure 4 shows a cooking pot 8 made of magnetic material placed on top plate 1.
The operating body 3 is raised by the attractive force of the magnet 6, and the switch 4 is released to close the alarm circuit and issue an alarm. The material of the cooking pot 8 may be non-magnetic, but most are magnetic, such as an enamel pot. Further, the embodiment is intended for an electromagnetic induction heater, and in this case, it is limited to a pot made of magnetic material, so there is no problem in practical use.

In addition to sounding a buzzer, the warning device can also be implemented by turning on a warning light.

The alarm device is installed at a suitable location on the bottom of the top plate, which has low heat resistance, so if the cooking pot shifts from the cooking surface and a portion of the pot is placed on the top plate, the alarm device will activate. This system has various effects because it can alert you to abnormal use and prevent the pan from overheating by placing a portion of the pan on the top plate.
