An evaporator chamber 30 is provided. The evaporator chamber 30 is connected to the inside of the refrigerator 29 via the cold air inlet 22 so as to take in the cold air from the evaporator chamber 30 into the inside of the refrigerator 29 .
The cold air in the refrigerator interior 29 is also communicated with the refrigerator interior 29 through the cold air return port 23 and the cold air return passage 37.
It is designed to be returned to the container chamber 30.

The evaporator 21 is connected to a condenser 19 protruding laterally from the evaporator chamber 30, a capillary tube 20, and an external compressor unit 41 connected to the refrigerator main body 40, with switching valves provided on their reciprocating paths. They are connected via 33°34. Then, by pressing a changeover switch (not shown) provided at an appropriate location, the changeover valve 43.
44 can be switched to a microwave oven with a refrigeration function or a refrigerator side. Here, 24 is a motor attached to the side wall forming the evaporator chamber 30, 25 is a fan that cools the condenser 19, and 26 is a fan installed in the evaporator chamber 30 to draw cool air near the evaporator 21. Fans 38 and 39 send the cold RMI to the refrigerator interior 29 through the cold air inlet 22, and the external compressor unit 41 of the cold RMI is connected to the capillary tube 20 and evaporator 2 of the microwave oven with refrigeration function through the switching valves 43 and 44.
It is a connecting member that connects to 1.

Furthermore, in order to provide this microwave oven with a refrigeration function with a cold R function and a heating function, a cover 31 made of a material that allows high frequency waves to pass through but does not allow cold air to pass through is provided at the opening of the waveguide 2. On the other hand, in order to prevent high frequencies from entering the evaporator chamber 30 side, punching plates 32 and 33 are provided at the cold air inlet 22 and the cold air return port 23 to prevent high frequencies from entering.
Heat medium (fluorocarbon gas) in the internal system path in the evaporator 21

The heated object A is the turntable 9
It is heated evenly as it rotates.

Next, when using the microwave oven with refrigeration function as a refrigeration device, first, press the changeover switch provided on the microwave oven with refrigeration function F3 to switch the changeover valves 43 and 44 to the side of the microwave oven with refrigeration function. The cooled Freon gas in the cooling circuit of the microwave oven with a refrigeration function exchanges heat with the cold air returning from the refrigerator interior 29 through the cold air return port 23 and the cold air return passage 37 at the evaporator 21. As a result, the cold air whose temperature has been lowered further is sent to the inside of the refrigerator 29 through the cold air inlet 22, and is sequentially circulated through the inside of the refrigerator 29 to be cooled. As a result, the liquid-cooled W body B placed on the turntable 9 is cooled u1.

At this time, even during cooling, by rotating the turn 7-bull D, the object B to be cooled can be uniformly cooled W and will not be frozen by the cold air.

As described above, this microwave oven with a refrigeration function enables heating, cooling, and cold cooking.

In addition, when the refrigerator main body 40 is not operated, refrigeration can also be performed by pressing the changeover switch and switching the switching valves 43, 44 to the refrigerator main body 40 side, but the external compressor unit 41 is normally When the microwave oven with refrigeration function finishes refrigerating, the refrigerator body 4
There are switching valves 43 and 44 on the 0 side, and general refrigeration is done by the refrigerator main body 40. In other words, cold 1QIF! When used as the refrigeration function of a microwave oven, it is mainly used for cold storage and rapid refrigeration.

Next, another embodiment of the present invention will be described with reference to FIG. The construction of this microwave oven with refrigeration function is the same as that of the above-mentioned microwave oven with refrigeration function, so the explanation will be omitted, but the refrigerator is of the same integrated type as the conventional one, and the compressor 18 is disposed inside the refrigerator body 50. Switching valves 43 and 44 are provided in the reciprocating path of the cooling U circuit connected to the compressor 18, respectively.
．． A microwave oven 21 with a refrigeration function and a capillary duplex 20 are connected to 44 . This microwave oven with a refrigeration function can also provide the same effects as those described above, and in this case, simply installing a new switching valve in the refrigerator you have on hand will allow you to use the refrigerator more effectively.

Further, although not shown, the following may be considered as another embodiment. That is, a method can be considered in which the refrigerator and the microwave oven with refrigeration function are connected by a cold air supply pipe and a cold air return pipe (preferably as flexible and small in diameter as possible) to cool the pipes with cold air.

Due to the above, the inside of the microwave oven with refrigeration function is cold.
By being able to use the inside of the refrigerator for both purposes, heating and cooling as well as cold cooking become possible. And even though it only has one compressor unit, it can be used with a refrigerator and a microwave oven with a refrigeration function.

Effect of the invention As described above, according to the present invention, the following effects can be obtained.

(1) The inside of the microwave oven can be used as the inside of the refrigerator,
By adding a refrigeration unit U to the microwave oven, heating and refrigeration or cold cooking can now be performed in the same refrigerator.

(2) It can be used as a microwave oven as it can be heated in 11 steps and can be refrigerated or cold cooked! The operating time of a single device increases, allowing for efficient utilization.

(3) Since the microwave oven can be used as a refrigerator, it can be used as a 2-cup refrigerator even in households that already have a refrigerator.

(4) By utilizing the inside of the 7M microwave oven and combining the microwave oven and refrigerator with a separate unit configuration, the weight of the microwave oven itself can be made as light as possible, and the installation space can be minimized as well. .

(5) It can be used in multiple ways by switching between a functionally integrated refrigerator and refrigerator and a refrigerator with only a refrigeration function, and can be used in multiple ways using a single compressor.The compressor can also be used for multiple purposes, reducing costs. Realize it.
