Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electric hot plate in which a plate is assembled to a hot plate body, and particularly, with a simple assembly structure, invasion of dust such as cooked food into the interior and thermal deformation of the hot plate body. The present invention relates to an electric hot plate that simultaneously prevents the occurrence of discoloration and discoloration (hereinafter simply referred to as “thermal deformation”).

[0002]

2. Description of the Related Art In recent years, various improvements have been made with the spread of electric hot plates. For example, the problem of heat deformation of the hot plate body due to heat transfer of the plate to the resin-made hot plate body is solved. Provides a gap so that the plate does not contact the hot plate body,
The heat of the plate was not transferred to the resin hot plate body.

However, if a gap is provided between the hot plate body and the plate, dust such as food will enter the inside of the hot plate body through the gap, so that the performance of the electric hot plate and hygiene are considered. Therefore, it became necessary to carry out cleaning work to remove dust such as cooked foods.

Therefore, Japanese Patent Laid-Open No. 4-227422 proposes a cooking top which eliminates the gap between the plate and the base to facilitate cleaning. Such a cooking-top, in addition to simplifying the cleaning, influences the power supply to the heating element depending on the detection result of whether there is a load placed on the heating element covered by the plate, It is also possible to prevent wasteful power consumption.

[0005]

However, the cooking top disclosed in Japanese Patent Laid-Open No. 4-227422 detects whether or not there is a load placed on the heating element, and the heating element is detected according to the detection result. Since it controls the power supply to the base, the plate is fixed to the base with a strain-cage module that detects such load, and it is necessary from the viewpoint of preventing thermal deformation of the base and simplifying cleaning. It had a complicated assembly structure as described above.

Therefore, the present invention has been made in order to solve the above-mentioned conventional problems, and has a simple assembling structure to prevent dust such as cooked food from entering the inside and heat deformation of the hot plate body. It is an object of the present invention to provide an electric hot plate that simultaneously prevents the above.

[0007]

An electric hot plate according to claim 1, which is formed to achieve this object, includes a plate having a flange portion provided around the plate, and a hot plate body to which the plate is assembled. An electric hot plate having: a heater box having an upper surface opening and filled with a heat insulating material; and a bracket for fixing the heater box away from the hot plate body, the plate being the heater box The flange portion of the plate is mounted on the hot plate body while being mounted on the upper surface opening portion.

In the electric hot plate having such a structure, the heater box is fixed to the hot plate main body by a bracket, and the plate is placed in the opening portion of the upper surface of the heater box. The structure to be attached to is simplified. In such an assembly structure, a space is formed between the heater box and the hot plate body,
Further, since the heater box is filled with the heat insulating material, the heat generated in the heater box is difficult to be transferred to the hot plate body. Further, since the space formed between the heater box and the hot plate body can increase the surface area of the flange portion of the plate that is in close contact with the hot plate body, it is possible to increase the heat radiation from the flange portion. , The heat of the plate is less likely to be transferred to the hot plate body. By these,
It is possible to prevent thermal deformation of the hot plate body.

At the same time, in the above-mentioned assembly structure, since the flange portion of the plate is in close contact with the hot plate main body, it is possible to prevent dust such as cooked food from entering the inside of the electric hot plate. It is possible to simplify the internal cleaning.

DETAILED DESCRIPTION OF THE INVENTION An electric hot plate according to the present invention will be described below with reference to FIGS. FIG.
FIG. 3 is a perspective view of the electric hot plate 1. FIG. 2 is an exploded perspective view showing an assembled state of the table 2 and the plate 3 which are hot plate bodies. FIG. 3 is a sectional view showing an assembly structure of the table 2 and the plate 3.

As shown in FIG. 1, in an electric hot plate 1 according to the present invention, a table 2 made of resin, wood or the like is used.
The plate 3 is attached to the central portion of the top plate (see FIGS. 2 and 3). A heater box 4 is arranged below the plate 3. A heater 8 (see FIG. 3) is built in the heater box 4, and the heater 8 includes various switches of the operation panel 5 attached to the upper end of the top plate of the table 2 or the bottom side of the top plate of the table 2. The plate 3 is heated from below based on the depression of the switch 7 or the like of the control box 6 fixed to the end,
As a result, heat treatment on the plate 3 becomes possible and cooking can be performed.

Further, as shown in FIG. 2, the heater box 4 is fixed to a bracket 10 below the top plate of the table 2 apart from the table 2. Further, the inside of the heater box 4 is filled with ceramic wool 9 which is a heat insulating material from the upper surface opening. Further, a flange portion 3A having a large surface area is formed on the periphery of the plate 3, and when the plate 3 is placed on the upper surface opening of the heater box 4, the lower side of the flange portion 3A is the table 2
It comes into close contact with the upper side of the top plate (see FIGS. 1 and 3). The heater 8 is located below the plate 3 (see FIG. 3), but is omitted in FIG.

Next, the assembling structure of the table 2 and the plate 3 will be described. As shown in FIG. 3, the table 2 and the heater box 4 are fixed by a bracket 10 and a screw 11. A space 12 is formed between the table 2 and the heater box 4 by fixing the table 2 and the heater box 4 separately with the bracket 10. Also, to assemble the plate 3 to the table 2,
It suffices to place the plate 3 in the upper opening of the heater box 4, and as a result, the lower side of the flange 3A of the plate 3 comes into close contact with the upper side of the top plate of the table 2 so that the space between the plate 3 and the table 2 is There are no gaps formed. Further, the top plate of the table 2 may be processed according to the simple shape of the plate 3 and does not require complicated processing or work.

As described in detail above, in the electric hot plate 1 according to the present invention, the bracket 10 is used to fix the heater box 4 away from the table 2, and the plate 3 is placed in the upper opening of the heater box 4. This simplifies the structure for assembling the plate 3 to the table 2 and forms a space 12 between the heater box 4 and the table 2, and the heater box 4 is filled with the ceramic wool 9 to form a heater box. 4 (to be exact, the heater 8) makes it difficult for the heat generated in the table 2 to be transmitted to the table 2, and further, the space 12 formed between the heater box 4 and the table 2 causes the flange of the plate 3 to be in close contact with the table 2. Part 3A
Since the heat of the plate 3 is less likely to be transmitted to the table 2 by increasing the surface area of the plate 3 and increasing the heat radiation from the flange 3A, thermal deformation of the table 2 can be prevented.

At the same time, in the above-mentioned assembly structure, the lower side of the flange portion 3A of the plate 3 is in close contact with the upper side of the top plate of the table 2, so that dust such as cooked food can enter the electric hot plate 1. Therefore, it is possible to simplify the cleaning of the inside of the electric hot plate 1.

The present invention is not limited to the above embodiment, and various modifications can be made without departing from the spirit of the invention. For example, although the plate 3 of the above-described embodiment is formed integrally with the flange portion 3A, when it is difficult to integrally form the flange portion 3A having a large surface area, the separately formed flange portion 3A is used. You may use what fixed to the plate 3 with a bolt etc.

Further, in the top plate of the table 2, if a heat insulating material is loaded in a portion where the lower side of the flange portion 3A of the plate 3 is in close contact, thermal deformation of the table 2 can be prevented more reliably.

[0018]

As is apparent from the above description, the bracket is used to fix the heater box by separating it from the hot plate body and mounting the plate on the opening of the upper surface of the heater box. The structure to be assembled to the plate body is simplified,
At the same time, since the flange portion of the plate is in close contact with the hot plate body, it is possible to provide an electric hot plate that simultaneously prevents the intrusion of debris such as food into the interior and the thermal deformation of the hot plate body. The effect to be performed is great.
