Description

An energy-saving refrigerator with air purification function

technical field

The invention relates to a refrigerator, in particular to a refrigerator equipped with an air cleaning device and realizing the purpose of energy saving through the air cleaning device.

technical background

Energy saving and environmental protection are the main directions for the development of refrigerators today. From the point of view of energy saving, the methods commonly used at present include increasing the thickness of the foam layer, improving the structure of the refrigerator door seal, and improving the insulation performance of the box to reduce the energy consumption of the refrigerator. The temperature sensing accuracy and timeliness of the sensor can reduce the fluctuation of storage temperature and also play a certain role in reducing energy consumption. However, the above-mentioned methods are passively saving energy by reducing cooling loss. In fact, improving the efficiency of the refrigeration system is the most direct and effective way to save energy. At present, the way to realize energy saving from the perspective of improving the efficiency of the refrigeration system is to use high-efficiency compressors, but due to the high cost, it is only used in a few high-end products.

As we all know, refrigerators and air conditioners are both refrigeration systems. In the refrigeration system, the high-temperature and high-pressure refrigerant compressed by the compressor must first be cooled in the condenser to become a high-pressure and medium-temperature liquid refrigerant, and then further cooled after being throttled by the throttling device, and then enters the evaporator to achieve the purpose of refrigeration. In the refrigeration system pipeline where the refrigerant comes out from the compressor to the throttling device, the lower the degree of cooling of the refrigerant, the better the cooling effect and the higher the efficiency of the refrigeration system. In the air conditioning system, fans are used to promote air convection to improve the condensation effect of the condenser, and various methods are used to reduce the temperature of the refrigerant before throttling, that is, to increase the degree of subcooling to improve the cooling effect. Theoretically, for every degree of subcooling, the cooling capacity can be increased by 0.85 percentage points. Therefore, increasing the subcooling degree of the refrigeration system is an important way to improve the efficiency of the refrigeration system and reduce energy consumption. However, in the refrigeration system of the refrigerator, due to the limitation of structure and space, the method of promoting air convection is not used to improve the condensation effect of the condenser. What is done at present is to increase the area of the condenser or improve the structure of the condenser The heat dissipation efficiency relies on the natural convection of air to cool the refrigerant coming out of the compressor. However, the cooling efficiency of natural convection is very low, and refrigerators are generally placed indoors, the space is relatively airtight, and the degree of air convection is inherently low. In addition, due to space constraints, refrigerators are generally placed against the wall, and refrigerator condensers are located in the refrigerator. On the rear side, the external space is narrow, and the condensation effect is even worse. The low efficiency of the condenser will inevitably lead to the low efficiency of the whole refrigeration system. But if adopt fan etc. to promote air convection like air-conditioning system, be subjected to the limitation of structure and space again, and simply arrange a fan to dissipate heat, itself also will consume energy, can take care of one thing and lose another.

From an environmental point of view. Health is a hot topic among people at present. With the aggravation of environmental pollution, the air quality is deteriorating day by day, and dirty air has become the number one killer of people's health today. According to the living conditions and layout habits of Chinese people, refrigerators are generally placed in the living room and kitchen. From a practical point of view, the refrigerator is not only a storage cabinet for storing food, but also a place prone to cross-contamination. If the air in the living room is polluted, when the refrigerator door is opened, dirty air will enter the refrigerator. Although many refrigerators are equipped with sterilization and deodorization devices, they cannot eliminate solid suspended particles such as dust in the air. Moreover, if the air in the refrigerator is unclean, when the refrigerator door is opened, it will also cause certain pollution to the living room air. Generally adopt indoor air purification device to purify indoor air at present. Many air purifiers draw in air through a fan, purify and filter it, and then blow it out. However, placing an air purifier indoors not only takes up a certain amount of space, but also the wind energy converted from electric energy is not fully utilized and wasted during the suction and exhaust process of the fan.

Contents of the invention

The object of the present invention is to address the above problems, to provide a refrigerator with energy-saving and environmental protection functions, which can improve the efficiency of the refrigeration system of the refrigerator by improving the condensation effect of the refrigerator condenser, achieve the purpose of energy saving, and by purifying and improving indoor air quality, avoid Refrigerator and indoor air cross-contamination, to achieve the dual purpose of energy saving and environmental protection.

In order to achieve the above object, the present invention arranges a interlayer on the top of the refrigerator, and an air cleaner is arranged in the interlayer to form an air cleaning room. The interlayer is formed by buckling the top of the refrigerator box with a downwardly protruding cover plate. The periphery of the cover plate is sealed with the top of the refrigerator. There are through holes on the front and rear sides, or through holes can also be set on the left and right sides. , as the air inlet or outlet of the air purification room. The air purification room sucks in and purifies the indoor air and blows it out, and promotes air convection around the condenser of the refrigerator by sucking in or blowing out the air, increasing the cooling effect of the condenser, improving the efficiency of the refrigeration system, and realizing the purpose of energy saving of the refrigerator.

The air purifier is a shell structure composed of an upper shell and a lower shell. There are screw holes on the edge of the upper housing, through which the air cleaner can be fixed on the inner surface of the cover plate with screws. The casing is provided with an air inlet and an exhaust port, and a catalyst for purifying and filtering air, a negative ion generator and a fan are arranged in the casing. Catalyst is installed at the suction port, and the suction port is connected with the air inlet of the air cleaning room, and the fan is installed at the exhaust port of the air purifier, and between the fan and the catalyst is a negative ion generator. The fan draws the air in the room through the air inlet, and first enters the air purifier for purification. The air purification is divided into two layers, the first layer is filtered and purified by the catalyst, the second layer is to increase the negative ions through the negative ion generator, and then discharge through the exhaust port, pass through the air channel in the purification room, and blow out from the air outlet.

The air outlet is located at the rear side of the air cleaning chamber, that is, on the side of the refrigerator condenser, and the air inlet is located at the front side, or at the left or right side. After the inhaled air is filtered and purified, it is discharged through the air outlet. Since the air outlet is located above the refrigerator condenser, the air convection around the condenser is greatly promoted by the blowing action of the air outlet, and the condensation effect is improved.

Of course, in the present invention, the air inlet of the clean room can also be arranged on one side of the condenser, and the air outlet can be arranged on the front side or the left and right sides of the refrigerator, and the condensing effect of the condenser can also be improved through the suction effect of the air inlet.

In order to further improve the degree of air flow around the condenser, the present invention can make the air inlet or outlet opening on the side of the condenser face downward. It can be designed as a flat trumpet shape with an opening that slopes downward. In this way, when the air inlet is located on the side of the condenser, since the hot air has a tendency to rise, what is inhaled is mainly the hot air around the condenser, and when the air outlet is located on the side of the condenser, it can blow the condenser itself to the greatest extent, thus Make the condensation effect more ideal.

In order to increase the degree of air convection and improve the condensation effect, a fan can also be set at the air outlet to blow air outward.

The cover plate of the air cleaning room is mounted on the top of the refrigerator through a buckle, which can be opened conveniently, so as to facilitate the maintenance, cleaning and replacement of parts of the air cleaner.

The catalyst for purifying and filtering air adopts a honeycomb mesh structure and is filled with activated carbon, which can absorb harmful smoke, odor, kitchen and living room odors, and can effectively filter out dust, pollen and mold with a diameter of 0.01um.

The beneficial effects of the present invention are: due to the use of the suction and exhaust functions of the air purification device, the air flow around the condenser can be promoted, the heat dissipation effect of the condenser can be improved, the refrigeration efficiency of the refrigerator can be improved, and the energy consumption of the refrigerator can be saved; The air purification device is installed to purify the indoor air, avoiding the cross-contamination of the indoor air and the air in the refrigerator, and realizing the purpose of environmental protection; since the air purification device and the refrigerator are integrated, the room space is also saved.
