Abstract

PURPOSE:To permit every kinds of cookings by employing only one set of driving motor by a method wherein a waveguide is provided so as to introduce high frequency electromagnetic waves to a fan casing in the compound cooker capable of effecting more than two kinds of cookings such as high frequency wave cooking, hot air cooking or the like. CONSTITUTION:The high frequency electromagnetic waves, generated in a high frequency electromagnetic waves generating source 3, are introduced to the fan casing 5 through the waveguide 8 to irradiate the interior of a cooking chamber 1 through the fan casing 5. According to such constitution, the high frequency electromagnetic waves are affected by a mixing effect due to the stirrer fan function of a hot-air circulating fan 7 and are irradiated into the cooking chamber 1 through a suction port 5a or a blow-off port. In this case, dirt such as soot generated in the cooking chamber 1 or the like is prevented from adhering to the high frequency electromagnetic waves generating source 3 by means of a partitioning plate 11. The leakage of the electromagnetic waves from a hot-air introducing port 5b at the back surface of the fan casing may be prevented by an electromagnetic wave shield plate 14. According to this constitution, every kinds of cookings may be performed by only one set of the driving motor.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a nine-component cooking device equipped with frequency heating preparation, hot air heating cooking, and at least 211 or more cooking functions.

Conventionally, this type of cooker has a high frequency generation source and a heat source in the cooker body with a built-in cooking chamber, and an electric liquid stirring device with a stirrer fan that transmits radio waves from the high frequency generation source to the cooking chamber. The hot air generated by the heat source is circulated into the refrigerator via a fan casing equipped with a hot air circulation fan. There are known devices that can uniformly heat a product with hot air, but 1. In this case, the electric stirrer and the fan casing are installed independently at positions separated from each other. ＃ It is generally accepted and takes 0 steps to assemble),
In addition, separate drive motors are required for the metallurgical fan and the hot air circulation 7a, which is expensive.

Inconveniences = The purpose of the present invention is to provide a composite cooking device that eliminates such inconveniences. In addition to providing a #7 uncasing that communicates with the cooking chamber,
The hot air circulation fan is housed in the fan casing, and is characterized in that round high frequency radio waves generated by the high frequency generation source are guided to the fan casing via a single waveguide.

Next, the present invention is attached to the illustrated example! I will clarify.

The one shown in Figure 1 has a high frequency generation source (3) consisting of a magnetron and a heat source (4) consisting of a gas nozzle in the lower space of the W4M main body (2) in which the cooking chamber (1) is placed. ), and a fan casing (5) having a front suction port (5a) communicating with the interior of the cooking chamber and air outlets (not shown) on both left and right sides is provided at the back of the cooking chamber (1), The motor shaft (of the drive motor (6)) is installed inside the fan casing (5).
Double suction hot air circulation fan (7) installed in 6a)
and guide the hot air from the heat source (4) to the hot air inlet (5b) on the back of the fan casing (5), and according to the operation of the hot air circulation fan (7), the hot air inlet (5b) Hot air is introduced into the #77 casing (6) from the air outlet, through the cooking chamber (1), and into the suction port (5a) K.
This system is designed to circulate air and is not particularly different from the conventional type described above, but according to the present invention, high frequency radio waves from a high frequency generation source (3) are sent through a waveguide (8). the fan casing (5);
The inside of the cooking chamber (1) was irradiated through the rays.

To explain this in more detail, the high frequency radio waves guided to the fan casing (5) through the waveguide (8) are stirred by the hot air circulation fan (7) which functions as a stirrup/closer. From the inlet (5a) and outlet to the cooking cabinet (1)
) is irradiated within.

A hot air circulation fan (
7) and a hot air introduction fan (9) are placed spaced apart from each other on the same axis in the front and back, and a stirrer fan frame is installed at an intermediate position on the coaxial shaft. The fan casing (
5), the inside of the Nl4N storage (1) is irradiated.

In addition, in order to prevent oil smoke and other dirt from adhering to the high frequency generation source (3), for example, as shown in Figure 1, the radio wave inlet of the fan casing (5) to which the waveguide (8) is connected, or 2. As shown in the figure, a partition plate ■ made of ceramic material that can transmit high-frequency radio waves is installed on the front of the Starts 7A4IO.
In addition, in order to prevent leakage of electricity from the 191 storage room (1),
It is OK to construct the front door (2) or the exhaust port a:I of the mud wall 'rJ with a radio wave seal r##, and also to prevent the radio waves from the back @(D hot air inlet (5b) of the fan casing (5) In order to prevent leakage, a radio wave shield plate a made of punched metal or the like is installed on the back side of the radio wave inlet of the casing (5).
4, and in order to prevent leakage of O radio waves through the motor shaft (61), a well-known Oλ/4 choke (not shown) is inserted into the insertion hole of the radio wave shield plate a4, for example, through which the shaft (6a) is inserted. Form.

Further, by arranging the combustion air O flow path toward the heat source (4) as shown in the figure, an air cooling effect is provided by the air flow, which is advantageous in that a separate cooling fan is not required.

Incidentally, in the above embodiment, the heat source (4) was gas A-.
Of course, this may be constructed with an electric heater housed in the IN storage (1), but in this case, the hot air introduction fan (9) inside the hot air introduction port (5a) would be a waste of public safety due to the noise.

In this way, according to the present invention, high frequency radio waves from a high frequency generation source are guided to the fan casing that accommodates the hot air circulation fan, and from the scissors 7 uncasing! 1141 It is designed to irradiate the inside of the laboratory, so there is no need for a separate radio wave stirrer. Also, the hot air circulation fan can also be used as a Neta-2 fan.
Alternatively, when a stirrer fan is provided, it can be installed coaxially with the ring fan, eliminating the need for a separate O drive motor exclusively for the stirrer fan, and eliminating the disadvantages of the conventional type C) 4b (DJC) described above. It has the effect of reliably eliminating the problem.
