Description

Technical Field

[0001] The present invention relates to the technical field of refrigeration, and in particular to a refrigeration device and a control method thereof. Background Art

[0002] Large-capacity air-cooled refrigerators are becoming increasingly popular. This type of refrigerator meets the needs of users for storing more food. However, due to their large capacity, use in a high-humidity environment will inevitably lead to the problem of more frost on the evaporator. In order to solve the evaporation of defrost water in the evaporating dish of large-capacity air-cooled refrigerators, prevent the evaporating dish from being full of defrost water and causing overflow, and ensure normal use of the refrigerator users, the industry usually adopts the solution of adding a defrost water evaporation tube in the evaporating dish.

[0003] In the related art, the solution of accelerating the evaporation of defrost water by using a defrost water evaporator can solve the problem of defrost water evaporation and prevent defrost water from overflowing from the evaporating dish. However, due to the wide variety of food stored in the user's refrigerator, the moisture generated by these food ingredients will eventually frost on the refrigerator evaporator, and defrost water will be generated during defrosting, resulting in a complex composition of the defrost water. Some acidic food ingredients will even cause the defrost water to be acidic. The defrost water evaporator is repeatedly immersed in the complex defrost water. Under the high-temperature use conditions of the refrigerator, the temperature of the compressor is very high, and the temperature of the defrost water evaporator will also rise accordingly. Long-term operation under high-temperature water-immersion conditions can easily cause the anti-corrosion protective material (PE heat shrink tubing or PA nylon coating protective layer) on the surface of the defrost water evaporator to be damaged, eventually leading to corrosion and leakage of the defrost water evaporator. The refrigeration medium of the entire refrigerator leaks and cannot refrigerate normally, affecting the user's normal use of the refrigerator. Summary of the Invention

[0004] The present invention aims to provide a refrigeration device that uses an air guide plate to direct air from a compressor compartment toward an evaporating dish, allowing the air after passing through a condenser to evaporate defrost water in the evaporating dish. The refrigeration component's conduit does not pass through a water chamber, preventing damage to the conduit.

[0005] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0006] According to one aspect of the present invention, there is provided a refrigeration device, comprising a housing, an evaporating dish, a refrigeration assembly and an air guide assembly; a refrigeration compartment and a compressor compartment are formed in the housing; the compressor compartment is arranged at the bottom of the housing; the evaporating dish is arranged in the compressor compartment; the evaporating dish is structured to form a water storage chamber with an open upper end for receiving defrost water in the refrigeration device; the refrigeration assembly is arranged in the housing; the refrigeration assembly comprises a compressor, a condenser, a throttle tube and an evaporator connected in sequence by a conduit; the condenser and the compressor are arranged in the compressor compartment; the conduit does not pass through the water storage chamber; a heat dissipation fan is arranged in the compressor compartment; the heat dissipation fan is used to drive the gas in the compressor compartment to flow from the condenser toward the compressor; the evaporating dish is arranged on the side of the compressor facing the condenser.

[0007] An air guide assembly is arranged in the compressor chamber; the air guide assembly includes a floating member and an air guide plate; the floating member extends into the water holding chamber so as to be able to rise and fall with the rise and fall of the water holding chamber; the air guide plate is rotatably arranged in the compressor chamber; the air guide plate is connected to the floating member so as to be able to rotate under the drive of the floating member; when the water level in the water holding chamber rises, the floating member can drive one end of the air guide plate to rotate toward the evaporating dish, so as to guide the gas flowing from the heat dissipation fan to the compressor and toward the water holding chamber.

[0008] The above technical features have at least the following beneficial effects and advantages:

[0009] As defrost water flows into the water chamber inside the evaporating dish, the water level rises, driving the float upward and rotating one end of the air guide plate toward the evaporating dish. This directs the air flowing from the cooling fan to the compressor toward the water chamber, allowing the air after passing through the condenser to evaporate the defrost water in the evaporating dish. Since the conduit does not pass through the water chamber, the defrost water in the evaporating dish does not need to evaporate through the conduit, protecting the conduit and effectively extending the life of the refrigeration equipment.

[0010] When the water level in the water chamber is low, the floating member moves downward under the action of gravity, driving the air guide plate to move away from the evaporating dish, so that the gas in the compressor compartment can flow toward the compressor to dissipate heat from the compressor.

[0011] The air guide plate allows some of the gas in the compressor to flow toward the compressor, while the remaining gas flows toward the evaporating dish. The floating plate gradually rises as the water level in the evaporating dish rises, driving the air guide plate toward the evaporating dish, thereby allowing more gas to flow toward the evaporating dish.

[0012] In some embodiments of the present application, the evaporating dish is located below the condenser and the heat dissipation fan; the air guide plate is formed with an air guide section, and the vertical projection of the air guide section is located between the heat dissipation fan and the compressor; when the floating part moves upward, it can drive the air guide section of the air guide plate to move downward toward the evaporating dish.

[0013] The above technical features have at least the following beneficial effects and advantages:

[0014] The evaporating dish is arranged below the condenser and the heat dissipation fan. When the floating part moves upward, it can drive the air guide section of the air guide plate to move downward toward the evaporating dish, so as to drive the gas to move downward toward the evaporating dish under the guidance or blocking of the air guide plate.

[0015] In some embodiments of the present application, the air guide plate is arranged horizontally, and the air guide plate is located above the condenser and the heat dissipation fan; a connecting rod is provided on the side of the air guide plate facing away from the compressor, and the end of the connecting rod facing away from the air guide plate is fixed to the floating part.

[0016] The above technical features have at least the following beneficial effects and advantages:

[0017] The air deflector is positioned horizontally above the condenser and cooling fan. When the water level in the evaporation dish is low, the floating plate minimizes the impact of air flowing from the cooling fan toward the compressor, ensuring proper heat dissipation from the compressor and condenser. Furthermore, when the water level in the compressor is high, the air deflector rotates downward, directing air toward the evaporation dish.

[0018] The air guide plate is set horizontally and located above the condenser and the heat dissipation fan to ensure that there is enough space to place the air guide plate in the limited space inside the compressor. The setting of the air guide plate will not cause the space inside the compressor chamber to be too large, effectively ensuring the space of the refrigeration compartment of the refrigeration equipment.

[0019] In some embodiments of the present application, a bent section is formed at one end of the air guide section facing the compressor; the bent section bends from the air guide section and extends close to the evaporating dish.

[0020] The above technical features have at least the following beneficial effects and advantages:

[0021] After being blocked by the air guide section, the gas flowing from the cooling fan toward the compressor can move downward toward the evaporating dish under the guidance of the bent section, so as to ensure that the gas can flow to the evaporating dish more directly and ensure the evaporation efficiency of the defrost water in the evaporating dish.

[0022] In some embodiments of the present application, the evaporating dish is at least partially located on a side of the heat dissipating fan and the condenser facing away from the compressor; and the floating member is located at an end of the evaporating dish facing away from the compressor.

[0023] The above technical features have at least the following beneficial effects and advantages:

[0024] The float is located on the end of the evaporating dish facing away from the compressor. As the water level in the dish rises, the float moves downward, driving the end of the air deflector facing away from the compressor downward, causing the air deflector to rotate. The end of the deflector facing the compressor rotates downward, directing the air flowing from the cooling fan to the compressor downward toward the evaporating dish. The float is located on the end of the evaporating dish facing away from the compressor, directly driving the air guide section of the air deflector downward.

[0025] In some embodiments of the present application, a rotating seat is provided on the top of the compressor or the condenser, and the air guide plate or the connecting rod is rotatably connected to the rotating seat around an axis in the front-to-back direction.

[0026] The above technical features have at least the following beneficial effects and advantages:

[0027] By setting the rotating seat, the lifting and lowering of the floating member can be converted into the rotation of the wind guide plate.

[0028] The above technical features have at least the following beneficial effects and advantages:

[0029] In some embodiments of the present application, in the horizontal direction, the evaporating dish is at least partially located between the heat dissipation fan and the compressor; and the vertical projection of the air guide section is projected into the evaporating dish.

[0030] The above technical features have at least the following beneficial effects and advantages:

[0031] The vertical projection of the air guide section is projected onto the evaporating dish, so that the air guide section of the air guide plate can directly guide the gas to the evaporating dish.

[0032] In some embodiments of the present application, the compressor and the heat dissipation fan are located above the water holding chamber so that a left-right through-gap is formed between the bottom end of the compressor and the bottom end of the heat dissipation fan at the upper portion of the water holding chamber.

[0033] The above technical features have at least the following beneficial effects and advantages:

[0034] A left-right through-gap is formed between the bottom end of the compressor and the bottom end of the heat dissipation fan at the upper part of the water chamber, so that the gas can flow above the water chamber, thereby improving the evaporation efficiency of the defrost water in the water chamber.

[0035] In some embodiments of the present application, when the water level in the evaporating dish is lower than a preset height, the lower end of the air guide plate is higher than the heat dissipation fan.

[0036] The above technical features have at least the following beneficial effects and advantages:

[0037] When the water level in the evaporating dish is lower than the preset water level, there is no need to guide the gas to the evaporating dish through the air guide plate. The lower end of the air guide plate is higher than the heat dissipation fan to ensure that more gas flows toward the compressor, thereby fully ensuring the heat dissipation of the compressor and condenser.

[0038] According to another aspect of the present invention, a method for controlling a refrigeration device is provided, wherein the method determines an operating mode of the refrigeration device in response to environmental information and the number of times the refrigeration device is opened and closed.

[0039] After determining that the refrigeration equipment is operating in the first working mode; when the refrigeration equipment is defrosting, the cooling fan and the compressor are started and stopped synchronously, and the cooling fan runs at a high speed during operation; after the refrigeration equipment is defrosted, the cooling fan runs at a high speed for a first preset time; the cooling fan rotates at a high speed, and the compressor and the cooling fan are started and stopped synchronously.

[0040] Other features and advantages of the present application will become apparent from the following detailed description, or may be learned in part by practice of the present application.

[0041] It should be understood that the foregoing general description and the following detailed description are exemplary and explanatory only and are not restrictive of the present application. BRIEF DESCRIPTION OF THE DRAWINGS

Figure 2 It is a structural schematic diagram of the rear side of the refrigeration equipment of the present invention. Figure 3 It is a schematic diagram of the refrigeration assembly 200 and the air guide assembly 500 of the present invention.

[0064] See Figures 1 to 3 This embodiment provides a refrigeration device for storing items at low temperatures. The refrigeration device can be a refrigerator, a refrigerated display cabinet, a refrigerated wine cabinet, or a freezer. The refrigeration device includes a housing 100, a door (not shown) rotatably disposed on the housing 100, and a refrigeration assembly 200 disposed within the housing 100.

[0065] A refrigeration compartment 110 is formed within the box 100, and food is placed in the refrigeration compartment 110 for low-temperature storage. The front of the refrigeration compartment 110 is open. Specifically, the box 100 is provided with an inner container, and the inner container has a refrigeration compartment 110 with a front opening. Items are placed in the refrigeration compartment 110 for low-temperature storage.

[0066] A press chamber 120 is further formed in the housing 100, and part of the refrigeration assembly 200 is disposed in the press chamber 120. In one embodiment, the press chamber 120 is disposed at the bottom of the housing 100. In other embodiments, the press chamber 120 is disposed at the top of the housing 100.

[0067] The door is rotatably mounted on the front side of the housing 100 to open or close the refrigeration compartment 110 in the housing 100 and to allow access to the refrigeration compartment 110. In this embodiment, the door is rotatably mounted on the front side of the housing 100 to open and close the refrigeration compartment 110.

[0068] Refrigeration assembly 200 transfers cold energy to the air in the refrigeration duct, providing cool air to refrigeration compartment 110. The refrigeration duct can selectively connect to refrigeration compartment 110 to direct air from the refrigeration duct into refrigeration compartment 110, thereby cooling refrigeration compartment 110. A refrigerant is provided within refrigeration assembly 200, which circulates within refrigeration assembly 200 for heat exchange.

[0069] In some embodiments, the refrigeration compartment 110 may include a refrigerator and a freezer, and the refrigeration duct can deliver cold air to the refrigerator and the freezer respectively, so that the air in the refrigeration duct can transfer cold air to the refrigerator and the freezer respectively to maintain the refrigeration environment in the refrigerator and the freezer.

[0070] There is a foam layer between the liner and the box body 100 , and the foam layer is filled with foam material. The foam material surrounds the upper and lower, left and right and rear side walls of the refrigeration compartment 110 , thereby insulating the refrigeration compartment 110 and maintaining the temperature of the refrigeration compartment 110 .

[0071] In some embodiments, the cabinet door includes a freezer door for covering the freezer compartment and a refrigerator door for covering the refrigerator compartment. The refrigerator door is operable to cover the front of the refrigerator compartment and the temperature-changing chamber for opening and closing the refrigerator compartment and the temperature-changing chamber. The freezer door is operable to cover the front of the freezer compartment for opening and closing the freezer compartment. The freezer door and the refrigerator door are spaced apart in the left-right direction.

[0072] Figure 4 It is a structural schematic diagram of the refrigeration component of the present invention in the press chamber. Figure 5 It is a partial structural schematic diagram of the refrigeration equipment of the present invention.

[0073] participate Figures 4 and 5 The refrigeration assembly 200 is used to release heat from the refrigeration equipment to the external environment, providing cooling to the refrigeration compartment 110 to maintain a low temperature environment within the refrigeration compartment 110. The refrigeration assembly 200 is disposed within the housing 100 and may include a compressor 210, a condenser 220, a throttle tube, and an evaporator 230, which are sequentially connected by a conduit. The outlet of the evaporator 230 is connected to the inlet of the compressor 210, thereby forming a channel for the circulation of the refrigerant medium within the compressor 210, the condenser 220, the throttle tube, and the evaporator 230.

[0074] In some embodiments, the compressor 210 and the condenser 220 are disposed in the compressor chamber 120. The compressor 210 and the condenser 220 are spaced apart from each other.

[0075] A cooling duct is provided within the housing 100, which is used to deliver cold air to the refrigeration compartment 110, thereby providing cooling to the refrigeration compartment 110. The refrigeration assembly 200 is used to exchange heat with the air within the refrigeration duct, transferring cooling energy to the air within the refrigeration duct, thereby generating cold air within the refrigeration duct. The cold air within the refrigeration duct is transferred to the refrigeration compartment 110, thereby cooling the refrigeration compartment 110.

[0076] The cooling duct communicates with the cooling compartment 110, allowing air to circulate between them. This transfers cooling energy from the cooling duct to the cooling compartment 110, and heat from the cooling compartment 110 to the cooling duct. The low-temperature, low-pressure liquid refrigerant in the evaporator 230 exchanges heat with the cooling duct and is converted into a low-temperature, low-pressure gaseous refrigerant. The low-temperature, low-pressure gaseous refrigerant in the evaporator 230 is then delivered to the compressor 210, where it is compressed into a high-temperature, high-pressure gaseous refrigerant.

[0077] The high-temperature, high-pressure gaseous refrigerant in compressor 210 is delivered to condenser 220, where it releases heat to the surrounding environment, converting it into a low-temperature, high-pressure liquid refrigerant. The low-temperature, high-pressure liquid refrigerant undergoes throttling and pressure reduction in the throttle tube, converting it into a low-temperature, low-pressure liquid refrigerant. The low-temperature, low-pressure liquid refrigerant is then delivered to evaporator 230 for heat exchange with the air in the cooling duct.

[0078] It should be noted that in some embodiments, a defrost mechanism is provided within the refrigeration equipment to defrost the refrigerator. The defrost mechanism can be a heater located near the evaporator 230, or it can be implemented by using the refrigerant within the refrigeration assembly 200. The defrost mechanism is not limited in this technical solution.

[0079] In some embodiments, the refrigeration equipment may further include a heat dissipation fan 300, which is disposed in the compressor compartment 120. The wind from the heat dissipation fan 300 can drive the flow of air in the compressor compartment 120 to dissipate heat from the condenser 220 and the compressor 210 in the compressor compartment 120. Air holes are provided on the circumference of the compressor compartment 120, extending through the periphery of the housing 100, for air exchange between the compressor compartment 120 and the external environment, thereby dissipating heat from the compressor compartment 120 to the outside of the housing 100.

[0080] In one embodiment, the condenser 220 and the compressor 210 are spaced apart from each other on the left and right sides, and the condenser 220 and the compressor 210 are respectively arranged near the left and right ends of the compressor chamber 120, and the heat dissipation fan 300 is arranged near the condenser 220. The heat dissipation fan 300 can be arranged on the side of the condenser 220 facing the compressor 210, or the heat dissipation fan 300 can be arranged on the side of the condenser 220 facing away from the compressor 210.

[0081] See again Figures 3 to 5 The refrigeration device also includes an evaporation dish 400, which is disposed within the compressor compartment 120. The evaporation dish 400 is configured to have a water-receiving chamber with an open top for receiving defrost water from the refrigeration device. The compressor compartment 120 is disposed at the bottom of the housing 100 to receive the defrost water.

[0082] In some embodiments, the evaporation dish 400 is disposed below the condenser 220 and the heat dissipation fan 300 .

[0083] In other embodiments, the evaporation dish 400 is disposed above the condenser 220 and the heat dissipation fan 300 .

[0084] In another embodiment, the evaporation dish 400 is disposed in front of or behind the condenser 220 .

[0085] In one embodiment, the compressor 210, the condenser 220, the throttle tube, and the evaporator 230 are sequentially connected via a conduit. The conduit is not disposed within the water storage chamber of the evaporating dish 400 so that the defrost water in the evaporating dish 400 does not damage the conduit, thereby protecting the normal operation of the refrigeration assembly 200.

[0086] In some embodiments, the conduit is not disposed within the water chamber of the evaporating dish 400. The refrigeration equipment may further include an air guide assembly 500 disposed within the compressor compartment 120. The operation of the heat dissipation fan 300 drives the flow of gas within the compressor compartment 120, thereby dissipating heat from the compressor 210 and condenser 220. The air guide assembly 500 can block and guide the gas flowing within the compressor compartment 120, thereby causing the gas within the compressor compartment 120 to flow toward the evaporating dish 400 and evaporate the defrost water within the evaporating dish 400. The air guide assembly 500 can direct the gas flowing from the heat dissipation fan 300 to the compressor 210 toward the evaporating dish 400.

[0087] Figure 6 It is a schematic diagram of the installation of the air guide assembly of the present invention. Figure 7 It is a structural schematic diagram of the air guide assembly of the present invention in one state. Figure 8 It is a structural schematic diagram of the air guide assembly of the present invention in another state.

[0088] See Figure 6 and Figure 8The air guide assembly 500 may include an air guide plate 510 rotatably disposed in the press chamber 120 . The air guide plate 510 rotates to different angles relative to the evaporating dish 400 to guide gases of different flow rates to the evaporating dish 400 .

[0089] In one embodiment, the evaporating dish 400 is disposed below the condenser 220 and the heat dissipation fan 300, and the air guide plate 510 is at least partially located between the heat dissipation fan 300 and the compressor 210 in the left-right direction. The air guide plate 510 rotates downward toward one end of the compressor 210, thereby blocking the gas flowing toward the compressor 210 and directing the blocked gas to the evaporating dish 400.

[0090] In some embodiments, the evaporating dish 400 is arranged above the condenser 220 and the heat dissipation fan 300, and the air guide plate 510 is at least partially located between the heat dissipation fan 300 and the compressor 210 in the left and right directions. The end of the air guide plate 510 facing away from the compressor 210 rotates toward the evaporating dish 400, thereby directing the gas to the evaporating dish 400.

[0091] In other embodiments, the evaporating dish 400 is disposed in front of or behind the condenser 220 , and the air guide plate 510 is at least partially located between the cooling fan 300 and the compressor 210 in the left and right directions. The air guide plate 510 can rotate forward or backward to guide the gas to the evaporating dish 400 .

[0092] In some embodiments, the air guide assembly 500 may further include a float 520 that extends into the water chamber and rises and falls with the water chamber. The float 520 acts as the buoyancy of the defrost water within the evaporating dish 400, allowing the float 520 to rise and fall with the water level. When the water level in the water chamber rises, the float 520 moves upward. When the water level in the water chamber drops, the float 520 moves downward accordingly.

[0093] In the present application, the air guide plate 510 is connected to a floating member 520 so as to rotate driven by the floating member 520. As the water level in the water chamber rises, the floating member 520 drives one end of the air guide plate 510 to rotate toward the evaporating dish 400, thereby directing the gas flowing from the cooling fan 300 to the compressor 210 toward the water chamber. When defrost water flows into the water chamber within the evaporating dish 400, the water level within the water chamber rises, driving the floating member 520 upward, causing one end of the air guide plate 510 to rotate toward the evaporating dish 400, thereby directing the gas flowing from the cooling fan 300 to the compressor 210 toward the water chamber. This allows the gas after passing through the condenser 220 to be used to evaporate the defrost water in the evaporating dish 400. Since the conduit does not pass through the water chamber, the defrost water in the evaporating dish 400 does not need to evaporate through the conduit, thereby protecting the conduit and effectively extending the life of the refrigeration equipment.

[0094] When the water level in the water chamber is low, the floating member 520 moves downward under the action of gravity, driving the air guide plate 510 to move away from the evaporation dish 400, so that the gas in the compressor chamber 120 can flow toward the compressor 210 to dissipate heat from the compressor 210.

[0095] The air deflector 510 is configured to allow some of the gas in the compressor 210 to flow toward the compressor 210, while another portion flows toward the evaporating dish 400. The floating plate gradually rises as the water level in the evaporating dish 400 gradually increases, driving the air deflector 510 toward the evaporating dish 400, thereby allowing more gas to flow toward the evaporating dish 400. Specifically, the higher the water level in the water chamber, the greater the rotation angle of the air deflector 510, and the more gas flows toward the evaporator 230. The air deflector 510 automatically rotates as the water level in the water chamber increases.

[0096] In this embodiment, the wind from the heat dissipation fan 300 drives the gas within the compressor compartment 120 from the condenser 220 toward the compressor 210. The air guide plate 510 directs the gas after passing through the condenser 220 toward the evaporation dish 400. This increases the temperature of the gas after passing through the condenser 220, which in turn allows the gas to better evaporate the defrost water within the evaporation dish 400. It should be noted that the heat dissipation fan 300 is positioned near the condenser 220, and the air guide plate 510 directs the gas after passing through the condenser 220 toward the evaporation dish 400.

[0097] Figure 9 It is a structural schematic diagram of the air guide plate of the present invention.

[0098] See Figures 4 to 9 The evaporating dish 400 is located below the condenser 220 and the cooling fan 300. The air guide plate 510 is formed with an air guide section 511. The vertical projection of the air guide section 511 is located between the cooling fan 300 and the compressor 210. When the floating member 520 moves upward, it can drive the air guide section 511 of the air guide plate 510 downward toward the evaporating dish 400. This drives the air, guided or blocked by the air guide plate 510, downward toward the evaporating dish 400, thereby evaporating the defrosted water in the evaporating dish 400 below.

[0099] In some embodiments, the air deflector 510 is arranged horizontally and positioned above the condenser 220 and the cooling fan 300. When the water level in the evaporating dish 400 is low, the floating plate has minimal impact on the gas flowing from the cooling fan 300 toward the compressor 210, thereby ensuring proper heat dissipation from the compressor 210 and condenser 220. Furthermore, when the water level in the compressor 210 is high, the air deflector 510 rotates downward, directing gas toward the evaporating dish 400 and evaporating the defrosted water therein.

[0100] The air guide plate 510 is arranged horizontally and is located above the condenser 220 and the heat dissipation fan 300 to ensure that there is enough space to place the air guide plate 510 within the limited space in the compressor. The arrangement of the air guide plate 510 will not cause the space in the compressor chamber 120 to be too large, and the space of the refrigeration compartment 110 of the refrigeration equipment is effectively guaranteed.

[0101] In other embodiments, the entire air deflector 510 is positioned between the compressor 210 and the condenser 220 in the horizontal direction, with the upper projection of the air deflector 510 in the horizontal direction falling onto the condenser 220. When the air deflector 510 is horizontal, the air deflector 510 does not block the flow of gas from the cooling fan 300 toward the compressor 210. When the air deflector 510 is rotated to form an angle with the horizontal direction, the gas can be directed to the evaporation dish 400.

[0102] In some embodiments, the air guide plate 510 is horizontally disposed and positioned above the condenser 220 and the heat dissipation fan 300. The section of the air guide plate 510 facing the compressor 210 is the air guide section 511. A bent section 512 is formed at the end of the air guide section 511 facing the compressor 210. The bent section 512 bends from the air guide section 511 and extends toward the evaporation dish 400. After being blocked by the air guide section 511, the air flowing from the heat dissipation fan 300 toward the compressor 210 can move downward toward the evaporation dish 400, guided by the bent section 512. This ensures that the air flows more directly toward the evaporation dish 400, thereby ensuring efficient evaporation of the defrost water within the evaporation dish 400.

[0103] In some embodiments, the lower surface of the guide section of the air deflector 510 is provided with a plurality of spaced guide ribs 513 spaced apart in the front-to-back direction. The guide ribs 513 extend in the front-to-back direction, and the spaces between adjacent guide ribs 513 form guide spaces. The guide spaces serve to guide the gas to the evaporation dish 400.

[0104] In some embodiments, a connecting rod 530 is provided on the side of the air deflector 510 facing away from the compressor 210. The end of the connecting rod 530 facing away from the air deflector 510 is fixed to the floating member 520. The floating member 520 is raised and lowered by the connecting rod 530, thereby driving the air deflector 510 to rotate.

[0105] In one embodiment, the evaporating dish 400 is at least partially located on the side of the heat dissipating fan 300 and the condenser 220 facing away from the compressor 210. A floating member 520 is located on the end of the evaporating dish 400 facing away from the compressor 210. When the water level in the evaporating dish 400 rises, the floating member 520 moves downward, driving the end of the air guide plate 510 facing away from the compressor 210 downward, causing the air guide plate 510 to rotate. The end of the air guide plate facing the compressor 210 rotates downward to direct gas flowing from the heat dissipating fan 300 to the compressor 210 downward toward the evaporating dish 400. The floating member 520 is located on the end of the evaporating dish 400 facing away from the compressor 210, thereby directly driving the air guide section 511 of the air guide plate 510 to move downward.

[0106] In one embodiment, a rotating seat is provided at the bottom of the compressor 210, and the air guide plate 510 or the connecting rod 530 is rotatably connected to the rotating seat around the axis in the front-to-back direction. Through the setting of the rotating seat, the lifting and lowering of the floating member 520 can be converted into the rotation of the air guide plate 510.

[0107] In another embodiment, a rotating base is provided at the bottom of the condenser 220 , and the air guide plate 510 or the connecting rod 530 is rotatably connected to the rotating base around an axis in the front-to-back direction.

[0108] In some embodiments, there is one rotating seat. In other embodiments, there are multiple rotating seats, which are spaced apart along the front-to-back direction, and the rotation axes of the multiple rotating seats coincide.

[0109] In one embodiment, the evaporating dish 400 is at least partially located between the heat dissipation fan 300 and the compressor 210 ; the vertical projection of the air guide section 511 is projected into the evaporating dish 400 , and when the air guide plate 510 rotates downward, the air guide plate 510 guides the gas downward, so that the air guide section 511 of the air guide plate 510 can directly guide the gas to the evaporating dish 400 .

[0110] In a specific embodiment, the left and right ends of the evaporating dish 400 face the compressor 210 and the condenser 220 respectively, the air guide section 511 of the air guide plate 510 is located above the section of the evaporating dish 400 facing the compressor 210, and the floating member 520 is provided at the end of the evaporating dish 400 facing away from the compressor 210.

[0111] In some embodiments, the compressor 210 and the heat dissipation fan 300 are located above the water chamber, so that a left-right through-gap is formed between the bottom end of the compressor 210 and the bottom end of the heat dissipation fan 300 at the upper part of the water chamber, so that the gas can flow above the water chamber, thereby improving the evaporation efficiency of the defrost water in the water chamber.

[0112] When the water level in the evaporating dish 400 is lower than a preset level, the lower end of the air guide plate 510 is higher than the heat dissipation fan 300. When the water level in the evaporating dish 400 is lower than the preset level, the air guide plate 510 is no longer required to direct the gas toward the evaporating dish 400. The lower end of the air guide plate 510 is higher than the heat dissipation fan 300, ensuring that more gas flows toward the compressor 210 and adequately dissipating heat from the compressor 210 and condenser 220.

[0113] Figure 10 It is a schematic diagram for judging the working mode of the refrigeration equipment of the present invention.

[0114] See Figure 10 Based on the above structure, the present application also provides a control method for refrigeration equipment:

[0115] In response to environmental information and the number of times the door of the refrigeration device is opened and closed, the operating mode of the refrigeration device is determined; the environmental information includes environmental temperature and environmental humidity.

[0116] During a defrost cycle, the system collects data on ambient temperature, ambient humidity, and the number of door openings and closings M. A defrost cycle can be the time period from the refrigerator's passage to the first defrost, or it can be the time period between adjacent defrost cycles on both sides.

[0117] It should be noted that, in the present application, a defrost cycle includes a preparation stage, a defrost stage and an evaporation stage.

[0118] The preparation phase is the period from the end of the previous defrost cycle to the start of defrost.

[0119] The defrost stage is the time period during which the refrigeration equipment defrosts. The evaporation stage is the time period after the defrost is completed until the defrost water in the evaporating dish 400 is evaporated.

[0120] In some embodiments, the preparation phase collects environmental information and data on the number of times the refrigeration device's door is opened and closed. The preparation phase collects and compares this data to determine the operating mode of the refrigeration device. During the defrosting and evaporation phases, the refrigeration device operates in the determined operating mode.

[0121] After the last defrost cycle ends and before defrost begins, multiple sets of ambient temperature data are collected during the preparation phase. During the preparation phase, multiple sets of ambient temperature data are collected at different time points.

[0122] It should be noted that at least three sets of ambient temperature data are collected. In some embodiments, different numbers of data, such as one, two, three, or four sets, may be collected.

[0123] During the preparation phase after the last defrost cycle ends and before defrost begins, multiple sets of ambient humidity data are collected. During the preparation phase, multiple sets of ambient humidity data are collected at different time points.

[0124] It should be noted that at least three sets of environmental humidity data are collected. In some embodiments, different numbers of data, such as one, two, three, or four sets, may be collected.

[0125] Judge environmental information according to different ambient temperatures and humidity.

[0126] The ambient temperature data and the ambient humidity data are obtained and compared with the preset temperature value and the preset humidity value to determine the environmental information. The obtained ambient temperature data and ambient humidity data are respectively recorded and counted by the system.

[0127] In one embodiment, three sets of ambient temperature data T1, T2, and T3 are obtained, and three sets of ambient humidity data U1, U2, and U3 are obtained.

[0128] In some embodiments, one, two, three, or four sets of ambient temperature data may be acquired.

[0129] When the ambient temperature is greater than or equal to the first preset temperature value, and the ambient humidity is greater than or equal to the first preset humidity value, it is determined that the external environment is a high temperature and high humidity environment.

[0130] In one embodiment, the first preset temperature value may be 30° C. In another embodiment, the first preset temperature value may be greater than or less than 30° C.

[0131] In one embodiment, the first preset humidity value may be 75%.In another embodiment, the first preset humidity value may be greater than or less than 75%.

[0132] After determining that the environment information is a high temperature and high humidity environment, the number of door openings and closings of the refrigeration equipment in the preparation phase M is obtained and the number of door openings and closings M is compared with the preset number of door openings.

[0133] When the external environment is a high temperature and high humidity environment and the door opening and closing times M is greater than or equal to the preset door opening and closing times, it is determined that the system operates in the first working mode.

[0134] When the external environment is a high temperature and high humidity environment and the door opening and closing times M is less than the preset door opening and closing times, it is determined that the system operates in the second working mode.

[0135] In one embodiment, the preset number of door opening and closing times is 20. In another embodiment, the preset number of door opening and closing times may be greater than or less than 20.

[0136] In one embodiment, when the ambient temperature is greater than or equal to a first preset temperature value and the ambient humidity is less than the first preset humidity value, the external environment is determined to be a high temperature and medium humidity environment, and the system is determined to operate in the third working mode.

[0137] In some embodiments, when the ambient temperature is lower than the first preset temperature value and higher than the second preset temperature value, the ambient temperature is determined to be a medium temperature environment, and the system is determined to operate in the fourth working mode.

[0138] In other embodiments, when the ambient temperature is lower than the second preset temperature value, the ambient information is determined to be a low temperature environment, and the system is determined to operate in the fifth working mode.

[0139] In some embodiments, the second preset temperature value is less than the first preset temperature value. In one embodiment, the second preset temperature value may be 15° C. In another embodiment, the second preset temperature value may be greater than or less than 30° C.

[0140] Figure 11 It is a structural diagram of the first working mode of the refrigeration equipment of the present invention.

[0141] See Figure 11 , determine that the system operates in the first working mode and the refrigeration equipment enters the defrost stage.

[0142] When the refrigeration equipment is defrosting, the heat dissipation fan 300 and the compressor 210 are started and stopped synchronously, and the heat dissipation fan 300 runs at a high speed during operation.

[0143] In some embodiments, when the refrigeration equipment is defrosting, the refrigeration equipment enters the defrost phase. During the defrost phase, the cooling fan 300 and the compressor 210 start and stop synchronously, with the cooling fan 300 operating at a high speed. At the beginning of defrost, the amount of defrost water in the evaporating dish 400 is low, and the cooling fan 300 and the compressor 210 start and stop synchronously to allow the cooling fan 300 to dissipate heat from the compressor 210, ensuring normal operation of the compressor 210.

[0144] At the end of the defrost phase, the defrost water level in the evaporating dish 400 is high. The air guide plate 510 in the compressor compartment 120 can direct the air in the compressor compartment 120 to the evaporating dish 400, thereby evaporating the defrost water in the evaporating dish 400. The heat dissipation fan 300 operates at a high speed to increase the air volume directed to the evaporating dish 400 and ensure efficient evaporation of the defrost water.

[0145] After defrosting, the refrigeration equipment enters the evaporation phase. During this phase, the compressor 210 and the cooling fan 300 are started and stopped asynchronously, maintaining the cooling fan 300 at a high speed for a first predetermined duration. After defrosting, the volume of defrosted water in the evaporating dish 400 is high. The air guide 510 directs the wind from the cooling fan 300 toward the evaporating dish 400, which operates at a high speed to improve the evaporation efficiency of the defrosted water in the evaporating dish 400.

[0146] After the cooling fan 300 runs at a high speed for a first preset time, the system determines that the defrost water in the evaporating dish 400 has completely evaporated or the system determines that the defrost water in the evaporating dish 400 has fallen below a preset water level. This means that the defrost water in the evaporating dish 400 has completely evaporated.

[0147] The first preset duration can be obtained through multiple experiments or settlements, and can be obtained by counting the duration of evaporation completion in the same environment.

[0148] In some embodiments, a water level sensor is provided in the evaporating dish 400 for detecting the water level in the evaporating dish 400 , and determining whether the evaporating dish 400 has completed evaporation of the defrost water based on the detected water level.

[0149] After the defrost water is evaporated, the heat dissipation fan 300 runs at a high speed, and the compressor 210 and the heat dissipation fan 300 are started and stopped synchronously to maintain heat dissipation for the compressor 210 and the condenser 220 .

[0150] After the evaporation stage is completed, re-determine the system's working mode.

[0151] Figure 12 It is a structural diagram of the second working mode of the refrigeration equipment of the present invention.

[0152] See Figure 12 , determine that the system operates in the second working mode and the refrigeration equipment enters the defrost stage.

[0153] When the refrigeration equipment is defrosting, the heat dissipation fan 300 and the compressor 210 are started and stopped synchronously, and the heat dissipation fan 300 runs at a high speed during operation.

[0154] In some embodiments, when the refrigeration equipment is defrosting, the refrigeration equipment enters the defrost phase. During the defrost phase, the cooling fan 300 and the compressor 210 start and stop synchronously, with the cooling fan 300 operating at a high speed. At the beginning of defrost, the amount of defrost water in the evaporating dish 400 is low, and the cooling fan 300 and the compressor 210 start and stop synchronously to allow the cooling fan 300 to dissipate heat from the compressor 210, ensuring normal operation of the compressor 210.

[0155] At the end of the defrost phase, the defrost water level in the evaporating dish 400 is high. The air guide plate 510 in the compressor compartment 120 can direct the air in the compressor compartment 120 to the evaporating dish 400, thereby evaporating the defrost water in the evaporating dish 400. The heat dissipation fan 300 operates at a high speed to increase the air volume directed to the evaporating dish 400 and ensure efficient evaporation of the defrost water.

[0156] After defrosting is complete, the refrigeration equipment enters the evaporation phase. During this phase, the compressor 210 and the cooling fan 300 start and stop asynchronously, and the cooling fan 300 operates at a high speed for a second preset duration. After defrosting is complete, the volume of defrosted water in the evaporating dish 400 is high. The air guide 510 directs the wind from the cooling fan 300 toward the evaporating dish 400, which operates at a high speed to improve the evaporation efficiency of the defrosted water in the evaporating dish 400.

[0157] It should be noted that the second preset duration is shorter than the first preset duration. When determining whether to enter the first or second operating mode, the system distinguishes based on the number of door openings and closings. If the external environment is high temperature and high humidity, and the number of door openings and closings M is greater than or equal to the preset number, the system is determined to be operating in the first operating mode. If the external environment is high temperature and high humidity, and the number of door openings and closings M is less than the preset number, the system is determined to be operating in the second operating mode. The more door openings and closings occur, the more moisture enters the refrigerator, and the more defrost water is stored in the refrigerator.

[0158] Compared to the first working mode, the second working mode requires fewer door openings and closings, so that the evaporation of the defrost water in the evaporating dish 400 takes less time than in the first working mode.

[0159] After the cooling fan 300 runs at a high speed for a second preset time, the system determines that the defrost water in the evaporating dish 400 has completely evaporated or the system determines that the defrost water in the evaporating dish 400 has fallen below a preset water level. This means that the defrost water in the evaporating dish 400 has completely evaporated.

[0160] The second preset duration can be obtained through multiple experiments or settlements. The second preset duration is obtained by counting the duration of evaporation completion in the same environment.

[0161] In some embodiments, a water level sensor is provided in the evaporating dish 400 for detecting the water level in the evaporating dish 400 , and determining whether the evaporating dish 400 has completed evaporation of the defrost water based on the detected water level.

[0162] After the defrost water is evaporated, the heat dissipation fan 300 runs at a high speed, and the compressor 210 and the heat dissipation fan 300 are started and stopped synchronously to maintain heat dissipation for the compressor 210 and the condenser 220 .

[0163] After the evaporation stage is completed, re-determine the system's working mode.

[0164] Figure 13 It is a structural diagram of the third working mode of the refrigeration equipment of the present invention.

[0165] See Figure 13, determine that the system operates in the third working mode and the refrigeration equipment enters the defrost stage.

[0166] When the refrigeration equipment is defrosting, the heat dissipation fan 300 and the compressor 210 are started and stopped synchronously, and the heat dissipation fan 300 runs at a high speed during operation.

[0167] In some embodiments, when the refrigeration equipment is defrosting, it enters the defrost phase. During the defrost phase, the cooling fan 300 and the compressor 210 start and stop synchronously, with the cooling fan 300 operating at a high speed. At the beginning of defrost, the amount of defrost water in the evaporating dish 400 is low, and the cooling fan 300 and the compressor 210 start and stop synchronously to allow the cooling fan 300 to dissipate heat and / or dissipate heat from the condenser 220, ensuring the normal operation of the compressor 210.

[0168] After defrosting, the refrigeration unit enters the evaporation phase. During this phase, the compressor 210 and the cooling fan 300 are started and stopped asynchronously, and the cooling fan 300 operates at a high speed for a third predetermined time. The air guide 510 directs the wind from the cooling fan 300 toward the evaporation dish 400, which operates at a high speed to improve the evaporation efficiency of the defrosted water in the evaporation dish 400.

[0169] It should be noted that the third preset duration is shorter than the second preset duration. When the system determines the third operating mode, the ambient humidity is greater than or equal to the first preset humidity value, unlike the first and second operating modes, which are determined based on the ambient humidity being less than the first preset humidity value. With relatively little water vapor entering the refrigeration equipment, the amount of defrost water in the evaporating dish 400 is low, and the heat dissipation fan 300 can operate for a shorter period of time to complete the evaporation of the defrost water.

[0170] After the cooling fan 300 runs at a high speed for a third preset time, the system determines that the defrost water in the evaporating dish 400 has completely evaporated or the system determines that the defrost water in the evaporating dish 400 has fallen below a preset water level. This means that the defrost water in the evaporating dish 400 has completely evaporated.

[0171] The third preset duration can be obtained through multiple experiments or settlements, and can be obtained by counting the duration of evaporation completion in the same environment.

[0172] After the defrost water is evaporated, the heat dissipation fan 300 runs at a high speed, and the compressor 210 and the heat dissipation fan 300 are started and stopped synchronously to maintain heat dissipation for the compressor 210 and the condenser 220 .

[0173] After the evaporation stage is completed, re-determine the system's working mode.

[0174] Figure 14It is a structural diagram of the fourth working mode of the refrigeration equipment of the present invention.

[0175] See Figure 14 , determine that the system operates in the fourth working mode and the refrigeration equipment enters the defrost stage.

[0176] When the refrigeration equipment is defrosting, the heat dissipation fan 300 and the compressor 210 are started and stopped synchronously, and the heat dissipation fan 300 runs at a medium speed gear during operation.

[0177] In some embodiments, when the refrigeration equipment is defrosting, the refrigeration equipment enters the defrost phase. During the defrost phase, the cooling fan 300 and the compressor 210 start and stop synchronously, with the cooling fan 300 operating at a medium speed. At the beginning of defrost, the amount of defrost water in the evaporating dish 400 is relatively low, and the cooling fan 300 and the compressor 210 start and stop synchronously, allowing the cooling fan 300 to dissipate heat from the compressor 210, ensuring normal operation of the compressor 210.

[0178] It should be noted that the operating speed of the cooling fan 300 in the medium speed gear is lower than that in the high speed gear. Compared to the ambient temperature during the first, second, and third operating modes, when the ambient temperature is higher than or equal to the first preset temperature value, when the system enters the fourth operating mode, the ambient temperature is lower than the first preset temperature value. Low ambient temperatures allow the system to dissipate heat more effectively naturally. The cooling fan 300 can operate at a relatively low speed to dissipate heat from the compressor 210 and / or condenser 220.

[0179] After defrosting is complete, the refrigeration device enters the evaporation phase. During this phase, the compressor 210 and the cooling fan 300 are started and stopped asynchronously, and the cooling fan 300 operates at a high speed for a fourth preset time period. The air guide 510 directs the airflow from the cooling fan 300 toward the evaporation dish 400, which operates at a high speed to improve the evaporation efficiency of the defrosted water in the evaporation dish 400.

[0180] In the fourth working mode, entering the evaporation stage, the heat dissipation fan 300 switches from the medium speed gear to the high speed gear to better evaporate the defrost water in the evaporating dish 400 and improve the evaporation efficiency.

[0181] In one embodiment, the fourth operating time is equal to the third operating time. In another embodiment, the fourth operating time is less than the third operating time.

[0182] After the defrost water is evaporated, the heat dissipation fan 300 runs at a medium speed, and the compressor 210 and the heat dissipation fan 300 are started and stopped synchronously to maintain heat dissipation for the compressor 210 and the condenser 220 .

[0183] After the evaporation stage is completed, re-determine the system's working mode.

[0184] Figure 15 It is a structural diagram of the fifth working mode of the refrigeration equipment of the present invention.

[0185] See Figure 15 , determine that the system operates in the fifth working mode and the refrigeration equipment enters the defrost stage.

[0186] When the refrigeration equipment is defrosting, the heat dissipation fan 300 and the compressor 210 are started and stopped synchronously, and the heat dissipation fan 300 runs at a low speed gear during operation.

[0187] In the fifth operating mode, the ambient temperature is relatively low. During the defrost phase, the cooling fan 300 and the compressor 210 start and stop synchronously, operating at a low speed. At the start of defrost, the amount of defrost water in the evaporating dish 400 is low, so the cooling fan 300 and the compressor 210 start and stop synchronously, allowing the cooling fan 300 to dissipate heat from the compressor 210 and ensuring its normal operation.

[0188] It should be noted that the operating speed of the cooling fan 300 in the low gear is lower than that in the medium gear. Compared to the ambient temperatures during the first, second, third, and fourth operating modes, the ambient temperature in the fifth operating mode is relatively low. Low ambient temperatures enhance the system's natural heat dissipation, allowing the cooling fan 300 to operate at a relatively low speed to dissipate heat from the compressor 210 and / or condenser 220.

[0189] After defrosting is complete, the refrigeration unit enters the evaporation phase. During this phase, the compressor 210 and the cooling fan 300 are started and stopped asynchronously, and the cooling fan 300 operates at a medium speed for a fifth preset time period. The air guide 510 directs the airflow from the cooling fan 300 toward the evaporation dish 400, which operates at a medium speed to improve the evaporation efficiency of the defrosted water in the evaporation dish 400.

[0190] In the fifth working mode, the evaporation stage is entered, and the heat dissipation fan 300 switches from a low speed gear to a medium speed gear to better evaporate the defrost water in the evaporating dish 400 and improve the evaporation efficiency.

[0191] In one embodiment, the fifth working duration is equal to the fourth working duration. In another embodiment, the fifth working duration is less than the fourth working duration.

[0192] After the defrost water is evaporated, the heat dissipation fan 300 runs at a medium speed, and the compressor 210 and the heat dissipation fan 300 are started and stopped synchronously to maintain heat dissipation for the compressor 210 and the condenser 220 .

[0193] After the evaporation stage is completed, re-determine the system's working mode.

[0194] It should be noted that, in one embodiment, the second preset duration is less than the first preset duration, the third preset duration is less than the third preset duration; the fifth working duration and the fourth working duration are equal to the fourth working duration.

[0195] The duration of the cooling fan operation during the evaporation phase Duration First preset duration 6h Second preset duration 4h The third preset duration 2h

[0196] In other embodiments, the operating speeds of the cooling fan at different gears are different, the high speed gear is higher than the medium speed gear, and the medium speed gear is higher than the low speed gear. For example:

[0197] Cooling fan speed gear Speed High gear 1200r / min Medium speed 1000r / min Low gear 800r / min
