Abstract

PURPOSE:To absorb shocks generated from a deep pan to be heated, suppress electromagnetic vibration of a heater coil, and sink the noise by affixing a heat resistant sheet to a top plate consisting of ceramic material. CONSTITUTION:A top plate 4 is formed from a ceramic material and arranged so as to cover the oversurface of a heater coil 2, and in the neighborhood thereof are furnished a thermo-sensitive component 6, which senses the bottom temp. of a deep pan 5 to be heated, and a blower fan 7 to cool the coils 2 and its surroundings. With heat resistant adhesives, a heat resistant sheet 8 consisting of polytetrafluoroethylene (Tefron(R)) resin is affixed to the oversurface of the plate 4. This allows absorbing shocks likely to occur during handling of the deep pan 5 which is placed on the surface of the plate 4, suppresses electromagnetic vibration of the heater coil, and reduces the noise.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to an induction cooker having a ceramic top plate.

BACKGROUND OF THE INVENTION In recent years, induction heating cookers have come into widespread use in order to rationalize and improve the sophistication of housework. Conventionally, this type of induction heating cooker has generally had a configuration as shown in Japanese Utility Model Application Publication No. 6233193. Below is the second part about its configuration.
This will be explained with reference to the figures. As shown in the figure, the induction heating cooker includes a main body 1 forming an outer shell, a heating coil 2 that heats an object to be heated by electromagnetic induction, and this heating coil 2.
a control section 3 that supplies and controls power to the heating coil 2; a top plate 4 made of ceramic that is provided on the top surface of the main body 1 and covers the top surface of the heating coil 2; It consists of a heating component 6 that detects the temperature and sends a signal to the control section 3 to control the temperature of the heated steel 5, and a blower fan 7 that cools the heating coil 2 and the control section 3. Cooking is performed with the heated steel 5 placed thereon.

Problems to be Solved by the Invention In such a conventional induction heating cooker, since the steel to be heated 5 is placed on the top surface of the top plate 4 made of ceramic and cooked, the inside of the steel to be heated 5 is agitated. Sometimes, the heated steel 5 tends to move, and the top plate 4 may be damaged due to the impact of the heated steel 5 against the top plate 4 during handling.Furthermore, the high frequency vibration of the heating coil 2 may cause the heated steel 5 to There was a problem in that noise was generated due to vibration between the i15 and the top plate 4.

The present invention solves the above problems and aims to provide an induction heating cooker that does not generate noise during use.

Means to solve problems In order to achieve the above object, the present invention provides a ceramic material.

It has a structure in which a heat-resistant sheet is attached to a top plate made of wood.

Function: Since the present invention has the above-described structure in which a heat-resistant sheet is attached to the top plate made of ceramic, it is possible to provide cushioning between the heated steel and the top plate and control vibrations.

EXAMPLE Hereinafter, an example of the present invention will be described with reference to FIG. In this embodiment, the same components as those shown in the above-mentioned conventional example are given the same reference numerals, and the explanation thereof will be omitted. The characteristic structure of this embodiment is in the top plate portion. That is, the top plate 4 is made of ceramic or the like and is arranged to cover the top surface of the heating coil 2, and near the top plate 2 is a heat-sensitive component 6 that detects the temperature of the bottom surface of the heated steel 5. A blower fan 7 is provided to cool the heating coil 2 and its surroundings. The upper surface of the top plate 4 is coated with tyfluoroethylene resin (
A heat-resistant sheet 8 made of a sheet made of Teflon (trade name) or a silicone rubber material is attached. For adhesion, a heat-resistant adhesive based on epoxy resin or silicone rubber is used. The thickness of the heat-resistant sheet 8 is 0
．． 2 mm or less is appropriate. In addition, a heat-sensitive component 6 for controlling the temperature is provided near the top plate 4, and the temperature of the heated steel 5 and the top plate 4 is set to about 220 degrees or less, so the sheet made of ethylene fluoride resin Alternatively, if a silicone rubber material or the like is used, it can withstand heat sufficiently.

In the above structure, the impact of the heated steel 5 against the top plate 4 can be absorbed when the heated steel 5 is placed on the top surface of the top plate 4 to which the heat-resistant sheet 8 is attached and stirred or handled. , electromagnetic vibrations generated when the heating coil 2 is energized can be absorbed.

Effects of the Invention As is clear from the description of the embodiments above, the induction heating cooker of the present invention includes a heating coil, a top plate made of ceramic that covers the upper surface of the heating coil, and a top plate located near the top plate. It is equipped with a heat-sensitive component that detects the temperature of the bottom surface of the heated pot, a blower fan that cools the heating coil and its surroundings, and a heat-resistant sheet pasted on the top surface of the top plate. When placed on the top surface for cooking, it is possible not only to prevent the heated steel from slipping, but also to absorb shocks caused by abnormal handling, and to suppress electromagnetic vibrations of the heating coil, thereby reducing noise.
