Description

Technical Field

[0001] The present invention relates to the technical field of refrigerators, and in particular to a refrigerator refrigeration cycle system. Background Art

[0002] Although air-cooled refrigerators have significant advantages in cooling efficiency and uniform temperature distribution, they also have some disadvantages that cannot be ignored. First, the fan will generate a certain amount of noise when it is running, which is especially obvious in a quiet environment at night. As time goes by, the fan will gradually increase its noise due to aging, which will not only further aggravate the noise problem, but also mean that users may need to bear the cost of replacing the fan or repairing it; secondly, there is the maintenance requirement. The fan needs to be cleaned regularly to keep it running at high speed, otherwise dust accumulation will affect the fan efficiency and increase noise; thirdly, the fan and circulation duct need to be installed in the air-cooled refrigerator, which to a certain extent reduces the effective storage space of the storage compartment; finally, the fan is a moving part, which has the risk of wear and failure. Once the fan has problems, the cooling effect of the entire refrigerator will be affected. The structural and technical complexity of the air-cooled refrigerator also leads to its relatively high production cost.

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0021] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", and "fixed" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection; it can be directly connected, or indirectly connected through an intermediate medium, or it can be internal communication between two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0022] like Figure 1 to Figure 2 As shown, a preferred embodiment of the present invention provides a refrigerator refrigeration cycle system, which includes a refrigerator liner (not shown in the figure), in which an air duct cover plate 1 is fixedly installed, and the rear space of the air duct cover plate 1 (i.e., the cavity between the air duct cover plate 1 and the rear wall of the refrigerator liner) is an evaporator cavity, in which an evaporator 2 is arranged, and the front space of the air duct cover plate 1 is a storage compartment.

[0023] The air duct cover plate 1 is provided with an air outlet 3 and an air return port 4 at intervals in the upper and lower parts. The air outlet 3 is a strip-shaped port and is arranged in the left and right directions. The bottom of the air duct cover plate 1 extends backward (i.e., the evaporator cavity) and is spaced apart from the bottom of the refrigerator liner to form the return port 4. Based on the above arrangement, the air outlet 3 and the return port 4 are both connected to the evaporator cavity and the storage compartment.

[0024] The system further includes a power supply module (not shown in the figure), an ion generator module 5 and electrodes 6 .

[0025] The refrigerator main control board is electrically connected to the power module, and the refrigerator main control board can control the on and off of the power module. The power module is a DC power module. The positive pole of the output end of the power module is connected to the positive pole of the input end of the ion generator module 5, and the negative pole of the output end of the power module is connected to the negative pole of the input end of the ion generator module 5. The power module can output stable DC low-voltage electricity for powering the ion generator module 5. The output end of the ion generator module 5 is connected to the electrode 6. The ion generator module 5 is used to convert the low voltage into a high voltage and output it through the electrode 6.

[0026] Furthermore, the ion generator module 5 is any one of a negative ion generator module, a positive ion generator module and a plasma generator module. In this embodiment, a negative ion generator module is preferably used.

[0027] like Figure 3As shown, the electrode 6 is a strip-shaped metal sheet structure, and its length is slightly less than the length of the air outlet. The electrode 6 is installed at the position of the air outlet 3 through an insulating bracket. Specifically, the insulating bracket includes two insulating vertical poles 7 arranged at intervals on the left and right, each insulating vertical pole 7 is fixedly installed on the top of the evaporator 2, and a shaft sleeve 8 is provided at the top of each insulating vertical pole 7. One long side of the electrode 6 is serrated, and a rotating shaft 9 is fixedly installed on the other long side opposite to the serrated long side. One end of the rotating shaft 9 extends into the shaft sleeve at the top of the first insulating vertical pole, and is rotatably and tightly connected to the shaft sleeve. The other end of the rotating shaft 9 extends into the shaft sleeve at the top of the second insulating vertical pole, and is similarly rotatably and tightly connected to the shaft sleeve. Based on the above arrangement, the serrated side of the electrode 6 faces the storage compartment, and the serrated tip of the electrode can be adjusted by rotating the electrode 6 up and down.

[0028] The air near the tip of the electrode is ionized under the action of high pressure to generate charged ions. Based on the interaction between the ions, an ion flow is formed and the air flow, i.e., ion wind, is driven. This replaces the fan to realize the circulation of cold air, which can effectively avoid the drawbacks of the fan in the prior art.

[0029] In addition, high voltage electricity can ionize oxygen molecules in the air to produce oxygen ions or active oxygen. Active oxygen reacts with oxygen molecules to produce ozone molecules. Ozone molecules can react with organic molecules to oxidize the organic matter into carbon dioxide and water. They can also react with organic matter such as bacteria, mold, viruses, and odor sources to degrade their molecular structures and achieve the effect of purifying the air.

[0030] In summary, in the refrigerator refrigeration cycle system described in the embodiment of the present invention, ion wind replaces the mechanical fan to realize the indoor air circulation of the refrigerator, and there is no mechanical moving parts to reduce noise pollution, while reducing the loss of parts and having a fast response speed. In addition, the charged ions generated after the air is ionized by high voltage electricity can mix with the microorganisms in the air to condense particles, kill the microorganisms, and achieve the effect of purifying the air.

[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
