Abstract

PURPOSE:To improve an efficiency by providing a sheetlike heater in contact with a thermally conductive material layer formed on the outer surface of a heating chamber structure. CONSTITUTION:When a sheetlike heater 8 is fed with electric power to be heated, heat generated therefrom is transferred to a heating chamber 6 through a heating chamber structure. In this case, since a thermally conductive material layer 7 is formed on the outer surface of a cavity top plate 5, the heat generated at the heater 8 is satisfactorily absorbed without reflecting on the surface of the plate 5, and desirably transferred into the chamber 6. Accordingly, there is no loss due to heat reflection, and heating is conducted with high efficiency.

Description

[Detailed description of the invention] (b) Industrial application fields The present invention relates to a heating control PM device.

0) Conventional a technique In Japanese Patent Application Laid-Open No. 62-299628, heating element structure 7) heating heating element 4 in which a planar heating element is provided closely on the keto surface;
It is shown. With such a groove bottom, a heating element such as a sheathed heater does not protrude into the heating chamber, so the space inside the heating chamber can be used effectively, and the inside of the heating chamber can be easily cleaned.

However, on the other hand, in such a configuration, the planar heating element is in the heating chamber N1.
11 Because it is outside the body, the heat generated there is tMf!
There was a problem that the signal could not be transmitted effectively into the room, resulting in poor efficiency.

(c) Problems to be Solved by the Invention The invention provides a heating cooker that can effectively utilize the space of a heating chamber and is highly efficient.

B) Means for Solving the Problems The information management device of the present invention comprises: a heating chamber component having a heating chamber; It is characterized by comprising a planar heating element provided in contact with the magnetic material layer.

(E) The heat generated by the working surface heating element is well conducted into the heating chamber via the layer of highly thermally conductive material formed on the outer surface of the heating chamber body.

(f) Example The drawing shows a heating cooker that is an embodiment of the present invention.

(1) is the outer shell of the cooking device, and (2) is the food entrance/exit.
Dij I'+ (3) is formed and is a front plate that constitutes the main body of the heating cooking test together with the outer a (1), and the front plate (2) has a door (not shown) for opening and closing the opening (3). figure)
is provided. (4> is the cavity provided on the back side of the opening (3) of the front plate (2), (5) is the cavity (4)
The cavity top plate is attached to the four sides of the heating chamber (6), and both of them constitute the heating chamber (6). That is, this cavity (+),
The large cavity plate (:I) corresponds to the heating chamber structure.

(7) is a good heat conductive material layer formed by applying a black heat-resistant paint with low heat reflection and good heat conductivity to the outer surface of the cavity top plate (5).

The composition of such a paint is as follows.

Epoxy modified silicone resin 2 (1.0% black M
Family (FetOx, 5lnt03.CuO, etc.) 17.5%
Extender pigments (MgO1S+01.41zO3, KtO, etc.)
21.5% anti-settling agent 1.
(1%M aromatic solvent 40.0% (8
is a planar heating element provided on the outside of the cavity top plate (4) so as to be in close contact with the good thermal conductive material 1# (7),
Surface where resistance heating wire is wrapped around mica board: 11 (Heater (
9), a heat-resistant insulator such as a mica board (10) < 11) is
−、Construct structure. , (12) is probably a mounting bracket for attaching the planar heating element (8) to the large cavity plate <5>, and (13) is a fitting for attaching the planar heating element (8) to the heating chamber (6) via the wave tube (14). It is a magnetron that supplies a high decoy wave (see Figure 2).
：No reason).

So, sheet heating element (8)! When heating is performed by energizing the knee, the heat generated is transferred to the heating chamber (
6). At this time, since the outer surface of the cavity top plate (5) has a good heat conductive material layer (7), the heat generated by the planar heating element (8) is transferred to the cavity top plate (5).
) Good without being reflected on the surface! 41 and is well transmitted to the heating chamber (6)? In other words, there is no loss due to heat reflection, and efficient heating is performed.

According to an experiment by a chaotic person, using the same planar heating element (8), 1f
At the time of J l f2, if a layer of good thermal conductivity material (7) is provided between the cavity top plate (5) and the surface 5 @ mature body (8) as in the present invention, the layer of material with good thermal conductivity (7) is directly attached to the cavity top plate (5). Planar heating element (8
), the temperature inside the heating chamber increased by 3f)''C to 40℃ by 17℃.
1! In the vicinity of the mature body (4), there is a heat-resistant insulator (10)
The temperature of (Ll) decreased by 50-60°C. In other words, this means that the heat generated by the planar heating element (8) is transferred to the cavity (top plate).
5) and was not reflected on the surface of the heating element (8) and was successfully transmitted to the cavity top plate (5) and into the heating chamber (6). It shows.

Therefore, if the electric power of the sheet heating element (8) is the same, 'I
LI thermal performance can be further improved, and less power is required to obtain the same heating performance.
Efficient heating #1p1. You can get profit.

Furthermore, since the planar heating element (8) is provided outside the heating chamber (6), the space in the heating chamber (6) can be used effectively, and it goes without saying that cleaning can be easily performed.

Note that the material layer (7) having good thermal conductivity is not limited to those described above, and for example, an inorganic black paint may be used, and other forming methods other than painting may also be used.

<g) Effects of the invention According to the invention, the heat generated by the planar heating element is 1 to 4
Efficient heating can be performed because the heat is transmitted well into the heating chamber through the tt material layer. In addition, since the planar heating body is provided outside the heating chamber, the space in the heating chamber can be used for +1 effect.
