Description

Detailed Description of the Invention The present invention provides a high frequency heating device 11t for thawing frozen foods, etc.
- Equipped with an exchangeable refrigerator 0 In recent years, frozen foods have been rapidly expanding into the RC food market.

Development of a refrigerated refrigerator with a 71"L, VC and a cold R1 [IC also has a freezer preservation machine II ￥!] for home use is underway. There are two ways to defrost frozen foods when cooking: one is to move the frozen food outside the refrigerator and allow it to thaw naturally, and the other is to defrost it using a high-frequency heating device such as a microwave oven. .

However, according to the former method, a microwave oven that also has a cooking function is expensive, and a microwave oven only for defrosting is not available on the market. The current situation is that it has not been released.

Therefore, in the present invention, the high circumference 1J1.
This is to provide a cold broken warehouse that incorporates a heat chamber and connects both high-frequency generators and gold-plated 1, which are heated to high temperatures outside the warehouse, with a waveguide, and prevents the waveguide from being exposed to the inner wall. be.

An embodiment of the present invention will be explained below based on the drawings.
1) In the case of the refrigerator body, the gap between the outer box and the inner box is filled with insulating material that is completely foamed on-site to form an insulating box. Inside the box is a partition wall + 21vc, and there are freezer compartments (3) and refrigerator compartments (41) above and below.
It is divided into. (5) is a machine room in the lower part of the cold R field main body (1) that stores pressure aJllt6+, etc.

(7) is a cold storage room (111) that closes the front opening of the freezer compartment (3) [with the room door, 18) is blurred on the inside of the company] (8a) has a t-refrigeration compartment (it is a R-shaped door that closes off the front opening of 41). (
4) A container provided at the inner lower part for storing vegetables, etc. (

Well, (IQ is a thawing chamber as a high-frequency heating vine that thaws the frozen food storage with sieve frequency so that it will bring good luck later). Q
In this embodiment, the JATF magnetron oscillator ul and the magnetron 1 are combined with a high frequency generator consisting of a source device 4 and a compressor (6) and a fan (b).
5) The pressure of the refrigeration system is 111 m inside the refrigeration system.
It is installed side by side with iamf61, and this high-frequency generator Q8 is equipped with a guide pipe (e) that sends radio waves to the electric stirring chamber (171) for the above-mentioned defrosting N cry.

There is an opening at the front @ 1kN, and a meat plate holder made of low dielectric resin or the like with an open top is inserted through the opening.The front rc of the inner plate has a handle -T. Figure 3 shows the thawing chamber j%-.
In the cross-sectional view of 6, is the cavity (ho) circle here? ``C1l'' is the front plate of the thawing chamber door, - is the choke electric body to prevent leakage of radio waves, and all of the thawing a+Msm It is a door punching plate that reflects electricity on the W surface of the cavity ().The position corresponding to the cold air outlet α4 on the rear wall of the cavity (E) and the front part of the large wall. niFi
A number of cold air circulation holes (26a) are drilled therein, and correspondingly, through holes (28a) are bored in the rear wall of the meat plater at positions corresponding to the cold air circulation holes (26a) rc. In this way, the cold air discharged into the refrigerator compartment (41) enters the thawing wtte from the rear ρ in the direction of the arrow in Fig. 2 and flows out to the front and upwards.The cold air is circulated here. Hole (26a
) is the solution [[1/10 of the wavelength λ of the high-frequency radio wave used is also a hole with a sufficiently small diameter. Therefore, the holes have a very large impedance to the electric current at that frequency, so the leakage of high-frequency radio waves from the cold air circulation hole (26a) is very small. Side face vCIIi Hole t17a having the same effect as the cold air circulation hole (26a) described above
) are provided, and the internal VC is driven by a motor.

← At least a plurality of waveguide elements (23a) in (23b)
), ← to (23b), and the connection between the dielectric part (23b) and the power supply part (23a) is a choke connection that can be inserted and removed from each other as shown in FIG. @ is a choke bond (
7) It is an electrical insulator that insulates the dielectric part (23b) and the power supply part (23a) from each other. lI! It has a through hole gat'' drilled in the back (1 m) of the container main body (l) and extends to the outside of the refrigerator to have an opening f'L.

A stepped portion is formed on the inside thereof, and the choke connection is made to the power feeding portion (23a) at this point. ! # The interior of the chamber (4) is cooled, and moisture in the refrigerator chamber (4) or the waveguide (to) condenses, causing water droplets to adhere to the inner 111 surface of the waveguide (2). . Since water has a very high dielectric constant, the high frequency radio waves emitted from the high frequency generator are absorbed by the water droplets and boil them, resulting in high frequency radio waves that reach the radio wave stirring chamber a'n. output is attenuated. Furthermore, the water droplets enter the inner circle of the high frequency generator due to the same η island, causing deterioration.

Therefore, a heat insulator vJt- is inserted into the dielectric part (23b) to seal the inside of the cavity. This heat insulator is made of polyvinyl chloride resin or the like that has a low dielectric constant and is transparent to high-frequency radio waves, and is molded to match the internal dimensions of the dielectric part (23b). This is made of a heat insulating material such as urethane resin that is also transparent to high frequency radio waves, and is pre-formed to fit the inner dimensions of the housing.
It is formed by storing it in a circle. The case member &I has a flange (43a) that protrudes outward at one end, and is shaped to wrap around the heat insulating material. Dielectric part (23b) from the free end
When the tip reaches near the opening, the flange part (43!L) enters and comes into contact with the fourth step part ■ of the opening, and the heat insulator is housed in the dielectric part (23b). Ru. Kof
The LK construction prevents dew condensation on the waveguide (2), and since the insulation material 444 is covered with the case member, it does not absorb moisture from the refrigerator compartment (4). high frequency radio wave v
There is no danger that the water in the cL lily will boil in the insulation material and cause deterioration of the insulation material. After that, the power supply part (23L) is choke-coupled to the t-dielectric part (23b).

The present invention is constructed as described above, and high-frequency heating Nt- is provided in the refrigerator compartment of the cold storage room, and a high-frequency generator that generates a relatively high temperature is installed outside the room. It is guided into the high-frequency heating chamber using a waveguide through the radio wave stirring chamber provided in the high-frequency heating chamber.

In the direct refrigeration unit configured to store and defrost frozen foods in the heating chamber, the waveguide connects a power supply section for the high frequency generator and a dielectric section extending from the stirring chamber to the storage section. It is divided into parts for choke coupling on the outside, and the joint is made so that the insulator is hermetically inserted into the dielectric part, so the dielectric part is cooled to the temperature inside the refrigerator room and dew buildup inside the waveguide is prevented. It is possible to prevent the attenuation of high-frequency radio waves and the intrusion of moisture into the high-frequency generator.In addition, it is also possible to incorporate a heat insulator!
