Abstract

PURPOSE:To make possible optional arrangement of a heating means, resulting expansion of the volume of a heating chamber of an oven said arrangement, access to the heating chamber of the heating means and sure cooling thereof, by taking out a part of cooling air for a high-frequency wave generating means, sending it to a fuel controller a pressure regulator, etc. of the heating means through a cylindrical guide. CONSTITUTION:A heating means is made up of an electromagnetic valve 115 to control fuel, a pressure regulator 116, an ignitor 117, a burner 118, a hot air circulation fan 11, etc., wherein the electromagnetic valve 115 and the pressure regulator 116, in particular, are integrated just above an air inlet 120 provided on a bottom plate 104. Cold air drawn by a cooling fan 105 cools a magnetron 106 and a high voltage transformer 107 to be passed to a main blow-off port 111. In that case, pressure in a container 108 will rise, causing said air to be blown off similarly from an auxiliary outlet 112 through a guide 114 to the air inlet 120 of the bottom plate 104. Said cooling air cools the electromagnetic valve 115 and the pressure regulator 116 located just above and at the same time supplies air for the combustion of the burner 118.

Description

[Detailed description of the invention] Industrial applications The present invention relates to a cooking device for general household use.

Conventional technology The conventional technique is shown in Fig. 4: Sea urchin magnetron 1. High voltage transformer 2. Solenoid valve 3. Cooker 4. The burner 6 and the cooling device were integrated, and the air supply path 2 from the cooling fan 6; heating means was arranged on the road to cool the heating means.

Alternatively, as shown in FIG. 5, ignition 7. A cooling air supply port 8 is provided directly below the heating means such as the burner 5, and the heating means is cooled by intake of air necessary for combustion and natural convection.

Problems to be Solved by the Invention However, in the case shown in FIG. 4, it is difficult to limit the air supply to the cooling device to cooling the heating means, and the effects of surrounding gaps are significant and the effect is insufficient. .

In addition, the built-in type has a standardized storage space, and if the heating, high-frequency generating means, and cooling device are integrated, it will end up compressing the open heating chamber and making it difficult to expand.

In addition, in the case shown in Fig. 6, the air supply path for combustion is limited by position, and the natural convection effect must wait until the ambient temperature rises. As a result, the heating means is located at a distance from the heating chamber. and heat insulation measures such as heat shields are required.

The present invention aims to solve such conventional problems.0 Means for Solving Problems/Means for Solving Problems A heating cooker C11 of the present invention, a cooling device for a high frequency generating means provided at the lower part of the main body of the device. Part II of the cooling air! /: It has a structure that leads to the heating means in the open part with a protruding, cylindrical guide.

Function: In the heating cooker of the present invention, the cooling air from the high-frequency generating means cannot be output to the machine 1 in its entirety, so a part of the cooling air is taken out from the cooling device J: In order to blow air through a cylindrical guide to the fuel control unit of the heating means, pressure regulator, etc.
It has the effect of making it possible to arbitrarily arrange the heating means, thereby increasing the capacity of the open heating chamber by 11, bringing the heating means closer to the heating chamber, and ensuring reliable cooling.

EXAMPLE Hereinafter, a heating device according to an example of the present invention will be explained with reference to the drawings.

FIG. 2 shows a grill section 102 on one side of the open section 101.
, shows a perspective view of the heating device on which the stove section 103 is placed.

FIG. 1 shows the lower part of the open part 101 seen through the bottom plate 104. 105 is a cooling fan, 106
1 is a magnetron for microwave oscillation, 107 is a high voltage transformer, and 10B is a holding box that houses these high frequency generating means. The holding box 108 has a cold air intake port 110° in front of the cooling fan 105 and a main air outlet 111. An auxiliary outlet 112 is provided on the side wall, and the main outlet 111 communicates with an exhaust pipe 113 and the auxiliary outlet 112 communicates with a guide 114.

FIG. 3 shows the heating means for the open portion 1Q1° at the top of the bottom plate 104. As shown in FIG. The heating means is a solenoid valve 115 that controls fuel.
Pressure regulator 1161 Igniter 117. Burner 118. It is composed of a hot air circulation fan 119, etc., and in particular, a solenoid valve 115.
The pressure regulator is concentrated right above the air supply port 120 provided in the bottom plate 104.

The air supply port 120 communicates with the guide 114 and the auxiliary air outlet 11
Reach 2. The imaginary line is - the heating chamber 121 of the garlic oven.
The bottom shows the holding box 108. In FIG. It cools the high pressure transformer 107 and reaches the main outlet 111. At this time, the pressure inside the holding box 10B rises and similarly blows out from the auxiliary outlet 112, passes through the guide 114, and reaches the air supply port 120 of the bottom plate 104. This cooling air is supplied to the solenoid valve 115 directly above the valve as shown in FIG. At the same time as cooling the pressure regulator 116, it also serves as air supply for the combustion chamber of the burner 118.

Effects of the Invention As described above, in the heating cooker of the present invention, a guide is provided from one end of the cooling device of the high-frequency generating means to send cooling air to the heating means, so that the heating means is ensured, and the heating means and the heating chamber are close to each other. This makes it possible to expand and increase the size of the heating chamber within the easily regulated outer dimensions.Also, in order to cool the conventional heating means, it was necessary to integrate the high frequency generating means and the cooling device, but with the present invention, each function can be improved. Therefore, the configuration can be arbitrarily configured.
