BACKGROUND OF THE INVENTION Conventional microwave ovens have only functioned as heating devices. That is, as shown in FIG. 4, the conventional microwave oven has a magnetron 1 that generates high frequency waves, and a waveguide 2 that introduces the high frequency waves from the magnetron 1 into the chamber interior 3. is gear 5, 6.7 by motor 4.
A rotary shaft 8 is provided which is rotated via the rotary shaft 8 . Also,
The interior 3 of the refrigerator is provided with a turntable 9 that is removably fitted onto the rotating shaft 8, and this turntable 9 is placed on a pulley 10 provided on the bottom surface of the interior 3 of the refrigerator. As a result, when the operation is started, the motor 4 is driven and the turntable 9 rotates while sliding on the pulley lO, and the heated object A placed on the turntable 9 is heated by the high frequency from the magnetron 1. Heats evenly.

On the other hand, as shown in FIG. 5, a conventional refrigerator has a compressor 18 attached to the lower part of the refrigerator main body, a condenser 19, a capillary tube 20. and a refrigeration principle configuration in which an evaporator 21 is connected, and a refrigeration compartment 17 having a cold air inlet 22 that takes in cold air from the evaporator 21 and a cold air return port 23 that returns the cold air to the evaporator 21 side. The fan 25 rotated by the motor 24 blows cold air into the refrigerator compartment 1.
7 to be refrigerated.

Furthermore, as shown in FIG. 6, an ice cream making device is constructed by placing a container 31 in which a cold storage agent 32 is sealed between a double-walled cylindrical body in the refrigerating compartment of a refrigeration device (see FIG. 5). Some foods are kept cooled for a long time until the temperature reaches around -15℃.

After that, ice cream cooking ingredients such as cream, milk, eggs, sugar, etc. are put into the container 31, and a stirring impeller 33 rotatably provided inside is manually operated using the rotary handle 34 provided on the top of the stirring impeller 33. By rotating and stirring the cooking materials, ice cream at a temperature of -4°C to -6°C is completed. Another method for making ice cream is to put the cooking ingredients in the container 31 in advance and stir them manually in the same manner as described above, then place the container 31 together in the refrigerator compartment of the refrigeration device and cool it. At this time, the container 31 is taken out at regular intervals and the ice cream in the container 31 is stirred. By repeating this, eventually -4℃~-
Ice cream at 6℃ is ready. Also, transparent ice can be made by placing water in the container 31 instead of the ice cream cooking ingredients and performing the same operation.

Problems to be Solved by the Invention However, as a matter of course, conventional microwave ovens cannot perform cold cooking such as refrigeration or ice cream production, and conventional refrigeration equipment cannot perform heated cooking. It could not be cooked cold.

The present invention has been made to solve the above-mentioned problems, and it is an object of the present invention to provide a microwave oven that can perform refrigeration and cold cooking such as ice cream production.

Means for Solving the Problems In order to solve the above problems, the present invention provides a heating unit that generates high frequency waves using a magnetron to heat the inside of the refrigerator, and a cold air inlet and a cold air return port that communicate with the interior of the refrigerator. A refrigeration mechanism unit that cools the inside with cold air, a rotating shaft located at the bottom of the refrigerator and rotated by a motor, a turntable that is removably fitted to the rotating shaft and rotates, and a turntable that protrudes from the bottom. The container includes a stirring impeller whose lower end is removably fitted onto the rotating shaft and rotates, and a container capable of stirring and cooling the contents.

With the configuration described in 2.2, during heating, the turntable is fitted to the rotating shaft, and the motor does not rotate the turntable via the rotating shaft, but the magnetron is activated, so that the object to be heated on the turntable is uniformly heated. heated to. In addition, by operating the refrigeration mechanism without operating the magnetron and sending cold air into the refrigerator via the cold air supply 1, the objects to be cooled in the refrigerator are cooled with cold air. When the object to be cooled is placed on the turntable 2 and the turntable is rotated, cooling is performed uniformly. Furthermore, when making ice cream, mix the ice cream ingredients in a container, place the container in the refrigerator so that the stirring impeller fits on the rotating shaft instead of the turntable, and then While operating the section to cool the container with cold air,
Start the motor. As a result, the cooking agent in the container is cooled and stirred by the stirring impeller to make ice cream. Similarly, transparent water can be obtained by using water as a cooking material, and cold cooking can be achieved by utilizing the refrigeration and rotation functions of a microwave oven.

Example Embodiments of the present invention will be described below based on the drawings.

Note that parts that are the same as those in conventional microwave ovens and refrigerators are given the same numbers.

Figures 1 to 3 are partially cutaway front views of a microwave oven with a refrigeration function showing an embodiment of the present invention. If so, FIG. 3 is a diagram showing the case where cold cooking is being performed. As shown in FIG. 1, a microwave oven with a refrigeration function has a structure similar to that of a conventional microwave oven, including a magnetron 1, a waveguide 2, a motor 4. Gears 5.6, 7, rotating shaft 8. It has a turntable 9 and a pulley 10. Further, a refrigeration mechanism section 15 is provided on the side opposite to the side where the magnetron 1 is arranged with respect to the interior 11 of the refrigerator. This refrigeration mechanism section 15 is provided with a compressor 18 in the lower part, like a conventional refrigeration device, and a condenser 19, a capillary tube 20, and an evaporator 21 are connected in series to this compressor 18. The evaporator chamber 16 in which the evaporator 21 is disposed has a cold air inlet 22 provided in front of the evaporator 21, a cold air return passage 29 that opens at the rear of the evaporator 21, and a cold air return passage 29 that communicates with the evaporator chamber 16. It communicates with the inside of the refrigerator 11 via a cold air return port 23 provided below. A motor 24 is provided between the evaporator 21 and the condenser 19, and has fans 25 and 26 attached to both ends of the shaft.The fan 26 cools the condenser 19, and the fan 25 cools the evaporator 21. Cold air in the vicinity of is sent into the refrigerator interior 11 via the cold air inlet 22. 27 and 2
Reference numeral 8 denotes an intake port and an exhaust port of the refrigeration mechanism section 15. Further, in order to provide this microwave oven with a refrigeration function with a refrigeration function and a heating function, a cover 36 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 frequency waves from entering the refrigeration mechanism section 15, punching plates 37 and 38 for preventing high frequency waves from entering are provided at the cold air inlet 22 and the cold air return port 23.

Overheating of the heat medium (fluorocarbon gas) in the internal system in the refrigeration mechanism section 15 is prevented. The inner surface material 39 forming the wall portion of the chamber interior 11 is made of a material that does not pass high frequency waves and cold air, and a heat insulating material 41 such as urethane material is provided between the inner surface material 39 and the outer surface material 40. There is. Also,
In order to prevent high frequency and cold air from leaking from the vicinity of the rotating shaft 8 toward the gear 7, the bottom surface 1 of the turntable 9 and the inside of the refrigerator 11 is installed.
1a comes into contact with each other, and the bottom surface portion 11a approaches the rotating shaft 8 at the portion through which the rotating shaft 8 passes, so that there is little clearance. In addition, a pipe (not shown) communicating with the outside is provided at the four parts of the bottom surface 11a of the refrigerator interior 1 where the pulley 10 is arranged, and the condensed water in the refrigerator interior 11 is discharged to the outside from this pipe. .

Furthermore, in addition to the above configuration, this microwave oven with a refrigeration function has a shaft portion 42a protruding from the bottom, as shown in FIG.
A container 43 is provided which has therein a stirring impeller 42 whose lower end is removably fitted onto the rotating shaft 8 and rotates.

An upwardly depressed recess 43a is formed in a portion of the bottom of the container 43 corresponding to the pulley 10.

It does not come into contact with the pulley 10 but comes into contact with the bottom portion 11a of the inside 11 of the refrigerator.

The operation of the above configuration will be explained.

First, when cooking by heating, the turntable 9 is fitted onto the rotating shaft 8 as shown in FIG. Activate Macnetron 1 while rotating. As a result, the heated object A placed on the turntable 9
High frequency is applied uniformly to the area to heat it.

Next, we will discuss the case of refrigeration. At this time as well, a turntable 9 is attached to the rotating shaft 8, but the magnetron 1
is not activated. The cooled fluorocarbon gas in the system of the refrigeration mechanism section 15 is returned from the refrigerator interior 11 to the cold air return channel 23. Heat is exchanged with the cold air returning via the cold air return passage 29. As a result, the cold air whose temperature has been lowered further is sent into the refrigerator interior 11 through the cold air inlet 22, and is sequentially circulated and cooled. As a result, the object to be cooled B placed on the turntable 9 is cooled. At this time, even during cooling, by rotating the turntable 9, the object to be cooled B can be uniformly cooled and will not freeze due to cold air.

Also, during refrigeration, especially when making ice cream or transparent ice, we will discuss. In this case, the turntable 9 used for heating and general refrigeration (chilling beer, watermelon, etc.) is removed and the container 43 is used. When making ice cream, cooking materials such as cream, milk, eggs, and sugar are stirred and placed in the container 43 in advance. Then, the rotating shaft 8 and the shaft portion 22 of the stirring impeller 22 protruding from the container 43 are fitted and set. At this time, by pressing the cold cooking operation button (not shown), the magnetron 1 is not activated, but the refrigeration mechanism 15 is started, cooling of the refrigerator interior 11 is started, and the motor 4 is started. For one hour, the stirring impeller 42 in the container 43 is rotated via the gears 5, 6.7 and the rotating shaft 8, and the cooking material (ice cream) in the container 43 is cooled while being rotated and stirred. snow,
After a while, the ice cream will be ready. 6 In addition, to obtain clear ice without cloudiness, the above ice can be obtained by using water as the cooking material and cooling while stirring in the same way as above. Up to this point, we have described the case of making ice cream or ice using the container 43, but in the configuration of the present invention, the container 43 can also be used for heating and stirring cooking (not shown). That is, for example, ingredients for stew are placed in the container 43, and as in the case of ice cream,
Heat it in the microwave while stirring. This allows stirring cooking that was previously impossible.

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 mechanism to the microwave oven, heating and refrigeration or cold cooking can now be done in the same refrigerator.

(2) Ice cream and ice cubes can now be made extremely easily because a refrigerator and a container that is automatically stirred by an impeller using a rotating shaft can be used at the same time inside the microwave oven. (3) In addition to being able to heat and cook food inside the microwave oven, it is now possible to use a container that is automatically stirred by an impeller that uses a rotating shaft, making it possible to heat and stir the food.

(4) Since microwave cooking and refrigeration or cold cooking can be performed, the microwave oven can be used more efficiently as an appliance, increasing its operating time.

(5) A microwave oven can be used as a refrigerator.

Even in households that already have a refrigerator, it can be used as a second refrigerator.
