Description

Technical Field

[0001] The present invention relates to the technical field of refrigerators, and in particular to an air-cooled horizontal refrigerator. Background Art

[0002] A freezer is another name for a refrigerator or freezer. The refrigeration principle of a freezer is that the compressor inside the freezer sucks in low-temperature, low-pressure refrigerant vapor and compresses it into high-temperature, high-pressure liquid refrigerant. Then, the high-temperature, high-pressure liquid refrigerant flows into the condenser to dissipate heat and becomes high-pressure, low-temperature liquid refrigerant. Then, the high-pressure, low-temperature liquid refrigerant enters the evaporator through the capillary tube. When the refrigerant enters the evaporator with a larger space from the narrow capillary tube, its internal pressure is released and it instantly vaporizes and absorbs heat to turn back into low-temperature, low-pressure refrigerant vapor, which is then sucked back into the compressor to form a cycle. A freezer can be divided into direct cooling and air cooling. Direct cooling refers to the evaporator being attached to the side wall of the refrigeration cavity to cool the refrigeration cavity. The disadvantage is that the air inside the refrigeration cavity does not flow and ice cubes are easily formed on its side wall. Air cooling refers to placing the evaporator in a cavity so that the air in the refrigeration cavity flows through the cavity to form cold wind, which is then blown into the refrigeration cavity. The advantage is that ice crystals will not form in the refrigeration cavity. Ice mainly occurs on the surface of the evaporator, and defrosting is required after working for a long time.

[0003] Although the ambient temperature in the refrigerator is low, low temperature can only inhibit the activity of bacteria. After the refrigerator is used for a long time, a large number of bacteria will still grow inside it, and these bacteria will not only cause the food in the refrigerator to deteriorate, but also produce unpleasant odors, which will mix with the smell of the food in the refrigerator, making people feel uncomfortable.

[0004] In view of this, in order to overcome the above technical problems, the present invention designs and develops an air-cooled horizontal freezer to solve the above technical problems. Summary of the invention

DETAILED DESCRIPTION

[0038] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] The embodiment of the present invention provides an air-cooled horizontal refrigerator, thereby solving the problem that a large number of bacteria may breed inside the refrigerator and generate odor after long-term use.

[0040] The technical solution in the embodiment of the present invention is to solve the above technical problems, and the overall idea is as follows: an ultraviolet lamp is arranged inside the refrigerating chamber 3, and ultraviolet rays are irradiated to the inside of the refrigerating chamber 3 when the cabinet door 2 is closed to eliminate microorganisms on the side walls and corners of the refrigerating chamber 3, and when the air inside the refrigerator is circulated and cooled, the air is filtered to absorb odors in the air of the refrigerator.

[0041] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0042] The present invention provides an air-cooled horizontal refrigerator, comprising: a cabinet body 1 and a cabinet door 2 hinged to the side of the cabinet body 1, a door seal 21 fixed at the edge of the cabinet door 2 and a refrigerating chamber 3 inside the cabinet body 1, and further comprising:

[0043] Circulating refrigeration and deodorizing device: The circulating refrigeration and deodorizing device is located inside the refrigerator and is used to cool and deodorize the refrigerating chamber 3;

[0044] No. 1 ultraviolet lamp 31: The No. 1 ultraviolet lamp 31 is fixed at two corners of the bottom of the side wall of one end of the refrigerating chamber 3, and is used to disinfect the side wall of the refrigerating chamber 3;

[0045] No. 2 ultraviolet lamp 32: The No. 2 ultraviolet lamp 32 is fixed at the bottom two corners of the side wall at the other end of the refrigerating chamber 3, and is used to disinfect the side wall of the refrigerating chamber 3 at that location.

[0046] The appearance of the present invention is substantially the same as that of an ordinary air-cooled horizontal freezer, and its exterior is composed of a cabinet body 1 and a cabinet door 2 hinged to the side of the cabinet body 1. A door seal 21 is fixed to the edge of the cabinet door 2 facing the cabinet body 1. When the cabinet door 2 is closed, the door seal 21 fits with the upper surface of the side wall of the cabinet body 1, so that the refrigerating chamber 3 forms a closed space. A circulating refrigeration and deodorizing device is provided inside the freezer. The air in the freezer is refrigerated and filtered and deodorized by the circulating refrigeration and filtering device. While providing low-temperature refrigeration conditions for the food in the freezer, the odor in the air of the refrigerating chamber 3 is removed, thereby achieving the effect of purifying the air and preventing the odors of different foods from mixing with each other and affecting people's appetite. In addition, a filter is provided at the bottom corners of the two end side walls of the refrigerating chamber 3. The first ultraviolet lamp 31 and the second ultraviolet lamp 32, when the cabinet door 2 is closed, irradiate ultraviolet rays into the refrigerator chamber 3 at the same time, and eliminate bacteria on the side walls and corners of the refrigerator chamber 3, and microorganisms in the flowing air, so as to prevent bacteria from multiplying and accumulating in the corners to form colonies due to long-term use of the refrigerator chamber 3, causing food to rot and produce unpleasant odors. Users need to thoroughly disinfect and clean the interior of the refrigerator to eliminate odors, which is very troublesome. The present invention can disinfect and sterilize the walls inside the refrigerator, refresh the air in the refrigerator, inhibit the reproduction of bacteria in the refrigerator chamber 3 to a certain extent, prolong the time for producing odors in the refrigerator, improve the preservation quality of the food inside the refrigerator, and reduce the frequency of cleaning the inside of the refrigerator by users.

[0047] As a specific embodiment of the present invention, the circulating refrigeration and deodorization device comprises:

[0048] Air outlet 33: The air outlet 33 is provided on the side wall of one end of the refrigerating chamber 3 where the No. 1 ultraviolet lamp 31 is located, and is a square hole arranged in a mesh shape;

[0049] Air inlet 34: The air inlet 34 is provided on the side wall of one end of the refrigerating chamber 3 where the second ultraviolet lamp 32 is located, and is a circular hole arranged in a mesh shape;

[0050] Filter tank 35: The filter tank 35 is disposed on one side of the air inlet 34 and is connected to the air inlet 34;

[0051] Filter plate 36: The filter plate 36 is disposed inside the filter tank 35, and its surface and edge are in contact with the side and groove edge of the filter tank 35;

[0052] Air channel 4: the air channel 4 is connected to one side of the filter plate 36, passes through the bottom of the cabinet 1, and is connected to the air outlet 33;

[0053] Air pump 41: the air pump 41 is arranged in the air passage 4 at the bottom of the cabinet 1, and its side is fixedly connected to the side wall of the air passage 4;

[0054] Compressor 42: The compressor 42 is fixed in the bottom side wall of the cabinet 1 at the end where the air outlet 33 is located;

[0055] Condenser 43: The condenser 43 is fixed on the inner wall of the cabinet 1 above the compressor 42 and communicates with the compressor 42;

[0056] Evaporator 44: The evaporator 44 is fixed inside the air passage 4 on the side of the compressor 42, and is communicated with the compressor 42 and with the condenser 43 through a capillary tube.

[0057] The present invention is provided with a circulating refrigeration and deodorizing device, which is used to cool and deodorize the air inside the cold storage room 3, wherein the air pump 41 inside the air channel 4 draws air toward one end along the direction of the air channel 4, so that an air flow is formed inside the air channel 4, so that the air pressure in the air channel 4 at the suction end of the air pump 41 is small, and the air pressure in the air channel 4 at the air outlet end of the air pump 41 is large, and one side of the air channel 4 with small air pressure is connected to the filter tank 35, and the middle part of the filter tank 35 is plugged with a filter plate 36, and the side part is an air inlet 34, so the air inside the cold storage room 3 will pass through the filter plate 36 from the air inlet 34 and be sucked into the air channel 4. In the present invention, the middle part of the filter plate 36 is provided with an activated carbon layer and a desiccant layer, and when the air passes through the filter plate 36, the odor molecules inside it will be desiccant by the activated carbon. The desiccant absorbs part of the air, thereby achieving the purpose of deodorization. The moisture mixed inside will also be absorbed by the desiccant, so that the air can be drier and the ice crystals condensed on the evaporator 44 can be reduced. An evaporator 44 is fixed inside the air channel 4 in the direction of the air outlet end of the air pump 41, which is connected to the compressor 42 and the condenser 43 fixed in the side wall of the cabinet 1. According to the refrigeration principle of the refrigerator, the refrigerant is vaporized inside the evaporator 44 to absorb the heat of the air around the evaporator 44. The air blown out by the air pump 41 passes through the evaporator 44, and after the heat is absorbed by it and becomes cold air, the cold air will enter the cold storage room 3 from the air outlet 33 due to the high air pressure inside the air channel 4, thereby lowering the temperature inside the cold storage room 3 and forming a cycle.

[0058] As a specific embodiment of the present invention, the evaporator 44 has a curved arc body, a heating wire 441 is provided on its surface, and a drain port 46 is provided at its bottom. The drain port 46 is connected to the water outlet 16 on one side of the cabinet 1 through a pipe.

[0059] Since a compressor 42 and other components are installed at the bottom of the side wall where the air outlet 33 of the cabinet 1 is located, the bottom wall of the cold storage room 3 on this side protrudes inward in a cylindrical shape, and the air channel 4 located in the wall is also bent into an arc shape. In the present invention, the evaporator 44 is designed to be bent into an arc shape so that it can be fixed to the bent air channel 4 here. The air flows out from the air outlet end of the air pump 41, and its flow direction changes and the flow rate decreases when passing through the bent air duct here, so that the contact time between the air and the evaporator 44 becomes longer, and the cooling effect on the air is better. The wall at this location is arc-shaped, and a drain port 46 is provided at the bottom of the arc-shaped wall. When the evaporator 44 defrosts, the heating wire 441 on its surface heats up and melts the ice crystals on its surface into water, and the water droplets will slide down along the side wall of the arc-shaped air channel 4 and directly flow into the drain port 46. The drain port 46 is connected to the water outlet 16 on one side of the cabinet 1 that is connected to the outside. Therefore, the water formed by the defrosting of the evaporator 44 in the present invention can automatically flow to the outside of the cabinet 1.

[0060] As a specific embodiment of the present invention, a U-shaped tube 45 is provided at the bottom of the drain outlet 46 , one end of which is connected to the bottom of the drain outlet 46 , and the other end is connected to the water outlet 16 , and the horizontal position of one end of the water outlet 16 is lower than the top of the drain outlet 46 .

[0061] In order to ensure that the water formed by the defrosting of the evaporator 44 can be smoothly discharged from the air channel 4 while ensuring the relative sealing of the entire refrigeration space, the present invention provides a U-shaped tube 45 at the bottom of the drain port 46, and water is filled at the bottom of the U-shaped tube 45 to form a communicating vessel structure. Since the horizontal position of the end of the U-shaped tube 45 that is connected to the water outlet 16 is lower than the top of the drain port 46, and the horizontal positions of the water surfaces on both sides of the U-shaped tube 45 are always the same, after the water formed by the defrosting of the evaporator 44 flows into the U-shaped tube 45, the liquid levels on both sides thereof rise. When the liquid level is higher than the water outlet 16, the corresponding water will flow out from the water outlet 16, so that the water level inside the U-shaped tube 45 is always lower than the top of the drain port 46 to avoid backflow. The residual water inside the U-shaped tube 45 can play a sealing role, isolating the internal air channel 4 and the water outlet 16, avoiding leakage of internal cold air, which increases the energy consumption of the machine body.

[0062] As a specific implementation of the present invention, a heating plate 451 is provided at the bottom of the U-shaped tube 45 .

[0063] In the present invention, in order to make the water in the U-shaped tube 45 always in liquid state and prevent it from freezing and losing its function of draining outwards, a heating plate 451 is provided at the bottom of the U-shaped tube 45. The heating plate 451 can heat the water inside the U-shaped tube 45 in real time to prevent it from freezing, so that the function of the communicating vessel is always effective, and the water formed when the evaporator 44 is defrosted cannot be discharged in time and accumulates in the air channel 4, causing ice on a larger area.

[0064] As a specific embodiment of the present invention, a fan-shaped groove 12 is provided at the top of one side of the cabinet 1, and a fan-shaped ultraviolet switch 13 is provided in the fan-shaped groove 12. The end of the ultraviolet switch 13 is rotatably connected to one end of the fan-shaped groove 12, and a coil spring is provided at the rotating position. A sensor 14 for turning on the ultraviolet lamp power is provided in the fan-shaped groove 12. When the ultraviolet switch 13 touches the sensor 14, the ultraviolet lamp power is turned on, and ultraviolet lamp No. 1 31 and ultraviolet lamp No. 2 32 emit light.

[0065] In order to prevent the ultraviolet light emitted by the ultraviolet lamp from causing harm to the human body when the cabinet door 2 is opened, the present invention sets that the first ultraviolet lamp 31 and the second ultraviolet lamp 32 will work only when the cabinet door 2 is closed. Therefore, a fan-shaped groove 12 is provided on the top plane of one side of the cabinet body 1, and a sensor 14 is provided inside the fan-shaped groove 12. When the ultraviolet switch 13 in the fan-shaped groove 12 contacts the sensor 14, the first ultraviolet lamp 31 and the second ultraviolet lamp 32 will be powered on. The ultraviolet switch 13 is also fan-shaped, and its end is rotatably connected to one end of the fan-shaped groove 12, and a coil spring is provided at the connection. When the cabinet door 2 is opened, the ultraviolet switch 1 Under the action of the elastic force of the coil spring at its end, the UV switch 13 is suspended in the fan-shaped groove 12. When the cabinet door 2 is closed, the side facing the cabinet body 1 presses the UV switch 13 into the fan-shaped groove 12, so that the UV switch 13 contacts the sensor 14, so that the No. 1 UV lamp 31 and the No. 2 UV lamp 32 are connected to the power supply, thereby emitting UV light to work. When the cabinet door 2 is opened again, since the UV switch 13 loses the pressure of the cabinet door 2, it is suspended again under the action of the coil spring, and the No. 1 UV lamp 31 and the No. 2 UV lamp 32 are disconnected from the power supply and stop working.

[0066] As a specific implementation of the present invention, the first ultraviolet lamp 31 is an arc-shaped long strip, and the lampshade of the second ultraviolet lamp 32 is a spherical surface.

[0067] The bottom edge of the end where the No. 1 ultraviolet lamp 31 is located in the present invention is protruded toward the inside of the refrigerating chamber 3 in a cylindrical shape because a compressor 42 is installed on its side. Therefore, the No. 1 ultraviolet lamp 31 is designed to be an arc-shaped long strip that can fit with the two side corners of this place to prevent the ultraviolet light emitted by it from being blocked by the protruding columnar wall, forming an obvious blind spot for irradiation. The No. 2 ultraviolet lamp 32 is fixed to the two bottom corners of the other end of the refrigerating chamber 3. Its lampshade is a spherical surface that can scatter the ultraviolet light emitted from its inside, expand its irradiation range, and improve the sterilization efficiency of ultraviolet rays.

[0068] As a specific implementation of the present invention, a ring-shaped handle 361 is fixed to the top of the filter plate 36 .

[0069] In the present invention, an activated carbon layer and a desiccant layer are provided inside the filter plate 36. Since both are consumables and will not be permanently effective, when the activated carbon adsorbs more substances and when the humidity of the desiccant is high, the filter plate 36 needs to be replaced. Since the filter plate 36 is located in the filter slot 35, in order to facilitate its removal, a ring-shaped handle 361 is fixed on the horizontal plate at the top thereof. The user only needs to hold the handle 361 to pull the filter plate 36 out of the filter slot 35, and then insert a new filter plate 36 to complete the replacement, which is convenient and quick.

[0070] As a specific implementation of the present invention, annular handles 22 are fixed to both end sides and the front side of the cabinet door 2 .

[0071] Since horizontal refrigerators are usually larger, the present invention has ring handles 22 fixed to both end sides and the front side of the cabinet door 2, so that the user can hold the handles 22 to open the cabinet door 2 at any position of the refrigerator.

[0072] As a specific embodiment of the present invention, a long strip heat dissipation hole 15 is opened on the side surface of the end where the condenser 43 is located on the cabinet 1, connecting the condenser 43 and the internal cavity where the compressor 42 is located.

[0073] The compressor 42 generates heat when it is working, and the condenser 43 also needs to dissipate heat to the outside when working. Therefore, the present invention has a row of long strip heat dissipation holes 15 on the side surface of one end of the cabinet 1, which connect the condenser 43 and the inner cavity where the compressor 42 is installed. The long strip heat dissipation holes 15 can allow external air to circulate on the surface of the condenser 43 and the compressor 42, taking away the heat around them and improving the working performance of the entire machine.

[0074] Working principle: The appearance of the present invention is substantially the same as that of an ordinary air-cooled horizontal freezer, and its exterior is composed of a cabinet body 1 and a cabinet door 2 hinged to the side of the cabinet body 1. A door seal 21 is fixed to the edge of the cabinet door 2 facing the cabinet body 1. When the cabinet door 2 is closed, the door seal 21 fits with the upper surface of the side wall of the cabinet body 1, so that the refrigerating chamber 3 forms a closed space. A circulating refrigeration and deodorizing device is provided inside the freezer, which is used to cool and deodorize the air inside the refrigerating chamber 3. The air pump 41 inside the air channel 4 draws air toward one end along the direction of the air channel 4, so that an airflow is formed inside the air channel 4, so that the air inside the air channel 4 at the air pump 41 draws air at the air channel 4 end. The air pressure is low, and the air pressure in the air channel 4 at the air outlet end of the air pump 41 is high, and one side of the air channel 4 with low air pressure is connected to the filter tank 35, and a filter plate 36 is plugged in the middle of the filter tank 35, and the side is an air inlet 34, so the air inside the refrigerating chamber 3 will pass through the filter plate 36 from the air inlet 34 and be sucked into the air channel 4. In the present invention, an activated carbon layer and a desiccant layer are provided in the middle of the filter plate 36. When the air passes through the filter plate 36, the odor molecules inside it will be partially absorbed by the activated carbon, thereby achieving the purpose of deodorization, and the moisture mixed inside it will also be partially absorbed by the desiccant, so that the air can be relatively dry and the ice crystals condensed on the evaporator 44 can be reduced; at the air pump 41 An evaporator 44 is fixed inside the air channel 4 in the direction of the air outlet end, which is connected to the compressor 42 and the condenser 43 fixed in the side wall of the cabinet 1. Using the refrigeration principle of the refrigerator, the refrigerant is vaporized inside the evaporator 44 to absorb the heat of the air around the evaporator 44. The air blown out by the air pump 41 passes through the evaporator 44 and absorbs the heat to become cold air. Since the air pressure inside the air channel 4 is relatively high, the cold air will enter the refrigerating chamber 3 from the air outlet 33, lowering the temperature inside the refrigerating chamber 3 to form a circulation, and at the bottom corners of the side walls at both ends of the refrigerating chamber 3, a No. 1 ultraviolet lamp 31 and a No. 2 ultraviolet lamp 32 are respectively installed. When the cabinet door 2 is closed, the two At the same time, ultraviolet rays are irradiated into the refrigerator chamber 3 to eliminate bacteria on the side walls and corners of the refrigerator chamber 3 and microorganisms in the flowing air, so as to avoid the bacteria in the refrigerator chamber 3 from multiplying and accumulating in the corners to form colonies due to long-term use, so that food becomes corrupt and produces unpleasant odors. It is very troublesome for users to thoroughly disinfect and clean the interior of the refrigerator to eliminate the odor. The present invention can disinfect and sterilize the walls inside the refrigerator, refresh the air in the refrigerator, inhibit the reproduction of bacteria in the refrigerator chamber 3 to a certain extent, prolong the time for producing odors in the refrigerator, improve the preservation quality of the food inside the refrigerator, and reduce the frequency of cleaning the inside of the refrigerator by users.

It should be understood by those skilled in the art that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the present invention.
