Description

Microwave defrosting refrigerator

Technical Field

The utility model belongs to the technical field of refrigerators, and particularly relates to a microwave defrosting refrigerator.

Background

In a cryogenic refrigeration system, a refrigerator includes finned tubes and a fan, and heat carried by a refrigerant flowing through the interior of the finned tubes is exchanged with air surrounding the finned tubes under the action of the fan. In the heat exchange process, due to the temperature difference effect, after a period of time, the surface of the finned tube can be frosted, condensed frost can block ventilation and influence the heat exchange effect, so that the refrigerating machine needs to defrost the finned tube.

At present, the defrosting modes of the refrigerating machine mainly comprise three modes: firstly, electrical heating defrosting, namely, an electrical heating rod is arranged on the finned tube to directly heat and defrost the finned tube. Because the finned tube is directly heated by the electric heating rod, the defects of long defrosting time, high heating power, high energy consumption and the like exist. And secondly, defrosting by water, namely defrosting by spraying water on the finned tubes. Although the mode is energy-saving, the mode is greatly influenced by the environmental temperature, and for example, the mode cannot be used in northern China when the environmental temperature is lower than zero centigrade. And thirdly, heating and defrosting, namely defrosting is realized by converting a refrigerating system to heat. The structure of the method has complex process and higher cost.

Therefore, how to manufacture a refrigerator, which has a fast defrosting speed, can effectively prevent the frost condensed during refrigeration from blocking ventilation and affecting the refrigeration effect, has low power consumption and is energy-saving, and the problem to be solved by the technical staff in the field is urgently needed.

Referring to fig. 1-2, the utility model provides a microwave defrosting refrigerator, which comprises a finned tube 1, a fan 3 for blowing air to the finned tube 1, and a microwave shielding case 2 covering the finned tube 1 and used for reflecting microwaves, wherein a microwave shielding net 21 for allowing the air blown by the fan 3 to enter and flow out of the microwave shielding case 2 and blow the finned tube 1 is arranged on the microwave shielding case 2, a microwave generator 4 is also arranged on the microwave shielding case 2, a waveguide 5 is arranged on the microwave generator 4, and the waveguide 5 is arranged inside the microwave shielding case 2.

Thus, in the process that the refrigerator participates in refrigeration, the refrigerant flows through the finned tube 1, the air blown out by the fan 3 can smoothly blow the finned tube 1 through the microwave shielding net 21, the refrigerant transfers heat to the finned tube 1, and the finned tube 1 and the air blown out by the fan 3 perform heat exchange. In the defrosting process, the microwave generated by the microwave generator 4 is transmitted through the waveguide 5 and then is transmitted inside the microwave shielding shell 2, and the microwave shielding shell 2 (including the microwave shielding net 21) has the function of shielding the microwave, so that the microwave cannot be transmitted out of the microwave shielding shell 2. Because the microwave has the characteristics of meeting metal reflection and working when meeting water molecules, the microwave can remove frost condensed on the finned tube 1, only works on the water molecules in the defrosting and heating process, and does not heat the finned tube 1, thereby reducing useless work and having the advantages of high defrosting speed, energy conservation and remarkable effect. And because the microwave shielding shell 2 has the function of reflecting the microwave, only a small part of the energy of the microwave is absorbed by the microwave shielding shell 2, thus the utilization efficiency of the energy of the microwave can be increased, and the energy consumed for defrosting can be further saved.

The microwave shielding shell 2 is also provided with a microwave leakage protector 6, and the microwave leakage protector 6 is electrically connected with the microwave generator 4.

If the microwave leaks out from the inside of the microwave shielding case 2 due to the damage of the microwave shielding net 21, etc., the microwave leakage protector 6 gives an alarm sound and disconnects the path of the microwave generator 4, so that the microwave generator 4 stops emitting the microwave. The staff hears the alarm sound and can overhaul the refrigerator.

The microwave shielding case 2 is formed in a rectangular parallelepiped shape, and a first long side wall of the microwave shielding case 2 is disposed opposite to the fan 3. The first long side wall is one of four long side walls in a rectangular parallelepiped shape, and any one of the four long side walls is sufficient.
