[0002] At present, refrigerators are widely used in daily life and supermarket sales due to their refrigeration and preservation functions. After long-term use, dust and other pollutants are easily accumulated on the top of the refrigerator. Since the height of the refrigerator is relatively high, it is difficult for users to reach the top of the refrigerator. When cleaning the top of the refrigerator, users need to use auxiliary tools to climb up to clean it. The method of users climbing up to manually clean the top of the refrigerator is relatively inefficient and has certain safety hazards, which brings troubles to users.

[0003] There is a refrigerator in the related art, characterized in that it includes an outer shell, a refrigerator door overlapped on the surface of the outer shell, a support plate placed inside the refrigerator fresh-keeping layer, and a base welded at the bottom of the refrigerator, fixed blocks are welded on both sides of the inside of the refrigerator fresh-keeping layer, and the fixed blocks are fixedly connected to the support plates through knobs; a concave block is welded on the outer surface of the outer shell, and a slider is clamped inside the concave block, and a first connecting rod is welded on the outer surface of the slider, and a cleaning assembly is arranged on the top of the refrigerator, and the cleaning assembly includes a square box placed on the top of the refrigerator; the cleaning assembly also includes a second connecting rod and cleaning cotton, one end of the second connecting rod is welded to the first connecting rod, and the other end is welded to the square box, and a cleaning box is clamped inside the square box, and the cleaning cotton is placed in the cleaning box; when the top of the outer shell needs to be cleaned, the pull ring on one side of the concave block can be pulled to move the square box on the top of the outer shell, and the top layer of the refrigerator is cleaned by the cleaning cotton in the cleaning box placed inside the square box, and when the cleaning cotton needs to be replaced or cleaned, the cleaning box clamped inside the square box can be directly pulled out to clean the cleaning cotton inside.

[0004] In the process of implementing the embodiments of the present disclosure, it is found that there are at least the following problems in the related art:

[0005] Since dust and other pollutants adhere to the top of the refrigerator for a long time, it is difficult to clean them with cleaning cotton, and the cleaning effect is poor. Moreover, when the cleaning cotton is used for cleaning, dust is easily caused to fly and fall, causing pollution to the environment where the refrigerator is located, and the user experience is poor.

[0006] It should be noted that the information disclosed in the above background technology section is only used to enhance the understanding of the background of the present application, and therefore may include information that does not constitute the prior art known to ordinary technicians in the field. Summary of the invention

[0007] In order to provide a basic understanding of some aspects of the disclosed embodiments, a brief summary is given below. The summary is not an extensive review, nor is it intended to identify key / critical components or delineate the scope of protection of these embodiments, but rather serves as a prelude to the detailed description that follows.

[0013] Optionally, both ends of the scraper are slidably connected to the two side edge areas opposite to the upper side wall of the box body. When the scraper slides, the scraper slides in a direction perpendicular to the length of the scraper to scrape pollutants on the upper side wall of the box body.

[0014] Optionally, one end of the scraper is rotatably connected to the upper side wall of the box body. When the scraper slides, the scraper performs a circular motion with the rotatably connected end as the center to scrape pollutants on the upper side wall of the box body.

[0015] In some embodiments, a control method for a refrigerator includes:

[0016] Obtain cleaning instructions for the upper side wall of the refrigerator body;

[0023] By setting a refrigeration module in the upper side wall area of ​​the cabinet, when the upper side wall of the cabinet needs to be cleaned, the refrigeration module can be used to refrigerate the upper side wall of the cabinet, so that the temperature of the upper side wall of the cabinet is lower than the dew point temperature in the environment, so that condensed water condenses on the upper side wall of the cabinet to soak the pollutants. The condensed water and pollutants are scraped off by the movement of the scraper to improve the cleaning effect of the upper side wall of the refrigerator. After being soaked in condensed water, the pollutants on the upper side wall of the cabinet are not easy to fly with the scraper, thereby reducing the risk of pollution of the environment where the refrigerator is located and improving the user experience. The cleaning time of the refrigerator is determined by obtaining the cleaning instruction of the refrigerator. When the cleaning instruction is obtained, the refrigeration module is controlled to start refrigeration on the upper side wall of the cabinet so that condensed water can be condensed on the upper side wall of the cabinet, and then the scraper is controlled to move to scrape off the condensed water and pollutants on the upper side wall of the cabinet, making the cleaning of the refrigerator more intelligent.

[0045] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present disclosure may be combined with each other.

[0046] Combination Figure 1-9 As shown, in some embodiments, the refrigerator includes: a box body 200, a refrigeration module 300 and a scraper 400. The refrigeration module 300 is arranged at the upper part or the lower part of the upper side wall of the box body 200, and is used to refrigerate the upper side wall of the box body 200; the scraper 400 is movably arranged on the upper side wall of the box body 200, and the lower side wall of the scraper 400 is slidably connected to the upper side wall of the box body 200.

[0047] The refrigerator provided by the embodiment of the present disclosure is provided with a refrigeration module 300 in the upper side wall area of ​​the box body 200. When the upper side wall of the box body 200 needs to be cleaned, the refrigeration module 300 can be used to refrigerate the upper side wall of the box body 200, so that the temperature of the upper side wall of the box body 200 is lower than the dew point temperature in the environment, so that condensed water condenses on the upper side wall of the box body 200 to soak the pollutants. The condensed water and pollutants are scraped off by the movement of the scraper 400, thereby improving the cleaning effect of the upper side wall of the refrigerator. After being soaked in condensed water, the pollutants on the upper side wall of the box body 200 are not easy to fly with the scraper 400, thereby reducing the risk of pollution of the environment where the refrigerator is located and improving the user experience.

[0048] Optionally, the refrigerator further includes a door body 500. The door body 500 is hinged to the box body 200 and is used to close the storage cavity inside the box body 200. In this way, food and other items are placed in the storage cavity inside the box body 200 for storage and preservation, and the door body 500 can open or close the storage cavity, which is convenient for taking and placing food and other items in the storage cavity, while reducing the leakage of cold energy in the storage cavity.

[0049] Optionally, the box 200 is a rectangular parallelepiped structure, and the long side of the box 200 is arranged in the vertical direction. In this way, the box 200 is more stable when placed, and the height of the box 200 is adapted to the height of the user, which is convenient for the user to use.

[0050] Optionally, the upper side wall of the box body 200 is a square end face. In this way, the heat exchange between the square end face and the refrigeration module 300 is more uniform, condensed water is better condensed on the upper side wall of the box body 200 for cleaning, and the scraper 400 is also convenient to set.

[0051] Combination Figure 1 As shown, in one embodiment, the refrigeration module 300 includes an evaporating coil, and the evaporating coil is connected to the refrigeration system of the refrigerator. In this way, the evaporating coil is arranged in the upper or lower area of ​​the upper side wall of the cabinet 200. When the upper side wall of the cabinet 200 needs to be cleaned, the refrigerant is controlled to flow into the evaporating coil for evaporation and heat absorption, thereby reducing the temperature of the upper side wall of the cabinet 200, so that the temperature of the upper side wall of the cabinet 200 is lower than the dew point temperature in the environment, and the moisture in the environment condenses on the upper side wall of the cabinet 200 to soak the dust and other pollutants, thereby improving the cleaning effect. The evaporating coil is connected to the refrigeration system of the refrigerator itself. When the upper side wall of the cabinet 200 needs to be cleaned, the refrigerant in the refrigeration system is controlled to flow into the evaporating coil for evaporation and heat absorption, thereby reducing the temperature of the upper side wall of the cabinet 200. There is no need to equip the evaporating coil with an additional refrigeration system, thereby reducing the cost of the refrigerator.

[0052] Alternatively, if Figure 2As shown, the refrigeration system includes a compressor 210, an evaporator 220 and a condenser 230. The evaporator 220 is laid on the side wall of the inner tank of the storage cavity, and the condenser 230 is arranged in the heat dissipation compartment of the refrigerator. The output end of the compressor 210 is connected to the input end of the condenser 230, and the output end of the condenser 230 is connected to the input end of the evaporator 220, and the output end of the evaporator 220 is connected to the input end of the compressor 210; the evaporation coil is connected between the input end of the compressor 210 and the output end of the condenser 230, and solenoid valves are arranged at both ends of the evaporation coil. In this way, the refrigerant compressed in the compressor 210 flows into the condenser 230 to condense and release heat, and the refrigerant in the condenser 230 flows into the evaporator 220 to evaporate and absorb heat, thereby cooling the internal environment of the storage cavity, and the refrigerant evaporated in the evaporator 220 flows into the compressor 210 again to be compressed to complete a refrigerant cycle. During this process, according to the cleaning requirements of the refrigerator, the solenoid valves at both ends of the evaporator coil can be controlled to open, so that part of the refrigerant flowing out of the condenser 230 flows into the evaporator coil for evaporation and heat absorption, thereby cooling the upper side wall of the cabinet 200. The refrigerant in the evaporator coil and the refrigerant in the evaporator 220 converge and flow into the compressor 210 for compression.

[0053] It can be understood that the refrigeration system also has necessary components such as a throttling and pressure reduction component, a four-way valve, a liquid storage tank, etc., which will not be described in detail here.

[0054] Combination Figure 3 As shown, in another embodiment, the refrigeration module 300 includes a semiconductor refrigeration chip, and the cold end of the semiconductor refrigeration chip is located above or below the upper side wall of the box body 200. In this way, the upper side wall of the box body 200 is quickly cooled by arranging the semiconductor refrigeration chip, so that the temperature of the upper side wall of the box body 200 is lower than the dew point temperature in the environment, and the moisture in the environment condenses on the upper side wall of the box body 200 to soak the dust and other pollutants, thereby improving the cleaning effect. When it is necessary to clean the upper side wall of the box body 200, the semiconductor refrigeration chip is controlled to be energized to reduce the temperature of the upper side wall of the box body 200 through its cold end.

[0055] Combination Figure 4 As shown, in one embodiment, the refrigeration module 300 is arranged below the upper side wall of the box body 200, and the top of the refrigeration module 300 abuts against the upper inner wall of the box body 200. In this way, the refrigeration module 300 can be hidden below the upper side wall of the box body 200, and the refrigeration module 300 is prevented from being exposed to the outside of the box body 200 and polluted by the environment. The top of the refrigeration module 300 abuts against the upper inner wall of the box body 200, so that the coldness of the refrigeration module 300 can be efficiently conducted to the upper side wall of the box body 200, thereby improving the cooling effect of the upper side wall of the box body 200, accelerating the generation of condensed water, and thus efficiently cleaning the pollutants on the upper side wall of the box body 200.

[0056] Optionally, the evaporator coil is disposed below the upper side wall of the box body 200, and the top of the evaporator coil abuts against the upper inner wall of the box body 200. In this way, when the refrigeration module 300 is an evaporator coil, the evaporator coil is hidden below the upper side wall of the box body 200. When the evaporator coil circulates refrigerant to evaporate and absorb heat, the cold energy of the evaporator coil is transferred to the upper side wall of the box body 200, so that condensed water is condensed on the upper side wall of the box body 200.

[0057] Combination Figure 5 As shown, in another embodiment, the refrigeration module 300 is arranged above the upper side wall of the box body 200, and there is a gap between the lower end of the refrigeration module 300 and the upper side wall of the box body 200. In this way, when the refrigeration module 300 is turned on, the upper side wall of the box body 200 can be refrigerated, so that the temperature of the upper side wall of the box body 200 is lower than the dew point temperature, thereby generating condensed water. Moreover, the refrigeration module 300 is exposed to the external environment, and can condense condensed water more efficiently. The condensed water condensed on the outer surface of the refrigeration module 300 drips on the upper side wall of the box body 200 under the action of gravity, and soaks the pollutants on the upper side wall of the box body 200. The condensed water is condensed by the upper side wall of the box body 200 and the refrigeration module 300 together, which improves the condensation efficiency and condensation amount of the condensed water, thereby improving the cleaning effect of the upper side wall of the box body 200.

[0058] Optionally, in the vertical direction, the width of the gap is greater than the thickness of the scraper 400. In this way, since the scraper 400 is movably arranged on the upper side wall of the box body 200 to scrape off pollutants on the upper side wall of the box body 200, the width of the gap between the refrigeration module 300 and the upper side wall of the box body 200 is set to be greater than the thickness of the scraper 400 to avoid interference between the scraper 400 and the refrigeration module 300.

[0059] Combination Figure 6 and Figure 7 As shown, a water collecting groove 240 is provided at the edge of the upper side wall of the box body 200, and the bottom end of the water collecting groove 240 is connected to the sewage pipe 250. In this way, the condensed water and dust and other pollutants on the upper side wall of the box body 200 can be scraped into the water collecting groove 240 by the scraper 400, and then discharged through the sewage pipe 250, without setting up an additional sewage discharge structure, reducing costs and improving user experience.

[0060] Optionally, water collecting grooves 240 are arranged at the four edges of the upper side wall of the box body 200, and the length of the water collecting grooves 240 arranged at each edge is the same as the length of the edge, and the four water collecting grooves 240 are connected end to end. In this way, the four side areas of the upper side wall of the box body 200 can collect condensed water and pollutants, and when the scraper 400 scrapes the pollutants on the upper side wall of the box body 200, the pollutant collection effect is improved.

[0061] Optionally, a dirt storage pan is further provided inside the box 200, and the upper end of the drain pipe 250 is connected to the water collecting tank 240, and the lower end is connected to the dirt storage pan. In this way, the condensed water and pollutants collected in the water collecting tank 240 are discharged into the dirt storage pan through the drain pipe 250 for storage, and the user can clean the pollutants collected in the dirt storage pan regularly.

[0062] Optionally, the dirt storage tray may be a water collection tray of a refrigerator.

[0063] In one embodiment, one drainage pipe 250 is provided, and the drainage pipe 250 is connected to the water collecting groove 240 provided at the rear edge of the upper side wall of the box body 200. In this way, the condensed water and pollutants scraped by the scraper 400 enter the multiple water collecting grooves 240 respectively. Since the multiple water collecting grooves 240 are all connected, by providing one drainage pipe 250 connected to the water collecting groove 240 located at the rear side of the upper side wall of the box body 200, the pollutants in the multiple water collecting grooves 240 can be discharged through one drainage pipe 250.

[0064] It can be understood that the side of the upper side wall of the box body 200 located on the installation side of the door body 500 is the front side, and the side opposite to the front side is the rear side of the upper side wall of the box body 200.

[0065] In another embodiment, three sewage pipes 250 are provided, and the three sewage pipes 250 are respectively connected to the water collecting grooves 240 provided at the three sides of the upper side wall of the box body 200 except the front side. In this way, since the front side wall of the box body 200 is open, it is convenient to take and put items, so the position of the front side wall of the box body 200 is not convenient to set the sewage pipe 250 for sewage discharge. Three sewage pipes 250 are provided, and the three sewage pipes 250 are respectively connected to the water collecting grooves 240 at the sides except the front side of the upper side wall of the box body 200, and sewage is discharged together through the three sewage pipes 250, thereby improving sewage discharge efficiency.

[0066] Combination Figure 1 and 8 As shown, in one embodiment, the two ends of the scraper 400 are respectively connected to the two side edge regions opposite to the upper side wall of the box body 200 in a sliding manner. When the scraper 400 slides, the scraper 400 slides in a direction perpendicular to the length of the scraper 400 to scrape the pollutants on the upper side wall of the box body 200. In this way, when the scraper 400 is moving, it slides on the upper side wall of the box body 200 in a direction perpendicular to the length of the scraper 400, and the pollutants on the upper side wall of the box body 200 are completely scraped off, thereby improving the cleaning effect of the upper side wall of the box body 200.

[0067] Specifically, the two ends of the scraper 400 are respectively slidably connected to the left and right side regions of the upper side wall of the box body 200. In this way, when the scraper 400 slides, the scraper 400 slides on the upper side wall of the box body 200 in the front-to-back direction, thereby improving the scraping effect of pollutants. Since the front side wall of the box body 200 is open, it is not convenient to connect the end of the scraper 400, so the two ends of the scraper 400 are respectively slidably connected to the left and right side regions of the upper side wall of the box body 200.

[0068] Optionally, the areas corresponding to the left and right sides of the upper side wall of the box body 200 are both provided with a slide groove 410, a transmission chain is provided inside the slide groove 410, and both ends of the scraper 400 extend into the corresponding slide groove 410 respectively and are connected to the conductive chain in the slide groove 410, and the transmission chain is driven by a driving motor. In this way, the scraper 400 is driven by the transmission chain to slide along the upper side wall of the box body 200, thereby improving the cleaning effect of the upper side wall of the box body 200.

[0069] Combination Fig. 9 As shown, in another embodiment, one end of the scraper 400 is rotatably connected to the upper side wall of the box body 200. When the scraper 400 slides, the scraper 400 performs a circular motion with the end of the rotatable connection as the center of the circle to scrape the pollutants on the upper side wall of the box body 200. In this way, when the scraper 400 is active, it performs a circular motion with one end of the scraper 400 as the center of the circle, thereby scraping off the pollutants on the upper side wall of the box body 200. When the scraper 400 performs a circular motion, the motion stroke is relatively short, and the pollutants on the upper side wall of the box body 200 can be scraped multiple times in the same time, thereby improving the cleaning efficiency.

[0070] Optionally, a driving motor is embedded in the upper side wall area of ​​the box body 200 corresponding to the connection end of the scraper 400, and the output shaft of the driving motor is fixedly connected to the end of the scraper 400. In this way, the driving motor drives the scraper 400 to perform reciprocating circular motion along its connection end.

[0071] Optionally, one end of the scraper 400 is rotatably connected to the corner area of ​​the upper side wall of the box body 200. In this way, the scraper 400 scrapes a larger area when it is active.

[0072] Optionally, two scrapers 400 are provided, and the ends of the two scrapers 400 are respectively rotatably connected to two corner regions adjacent to the upper side wall of the box body 200. In this way, by providing two scrapers 400, the scraping efficiency of pollutants on the upper side wall of the box body 200 is further improved.

[0073] Specifically, the two scrapers 400 are moved alternately, so that interference between the two scrapers 400 can be avoided.

[0074] Combination Fig.10 As shown, in some embodiments, a control method for a refrigerator includes:

[0075] S01, the processor obtains a cleaning instruction for the upper side wall of the refrigerator body;

[0076] S02, the processor controls the refrigeration module to start cooling the upper wall of the refrigerator;

[0077] S03, the processor controls the scraper to move to scrape pollutants on the upper wall of the refrigerator.

[0078] By adopting the control method for a refrigerator provided by the embodiment of the present disclosure, the cleaning time of the refrigerator is determined by obtaining the cleaning instruction of the refrigerator. When the cleaning instruction is obtained, the refrigeration module is controlled to start refrigeration of the upper side wall of the cabinet so that condensed water can condense on the upper side wall of the cabinet. Then, the scraper movement is controlled to scrape off the condensed water and pollutants on the upper side wall of the cabinet. While improving the cleaning effect of the upper side wall of the refrigerator, the cleaning of the refrigerator is made more intelligent.

[0079] Optionally, the processor controls the scraper to move to scrape pollutants on the upper side wall of the refrigerator, including: the processor controls the drive motor of the scraper to start, so as to drive the scraper to move to scrape pollutants on the upper side wall of the refrigerator. In this way, since the scraper is driven by the drive motor, the processor controls the drive motor to start to drive the scraper to move, thereby scraping pollutants and condensed water on the upper side wall of the refrigerator.

[0080] Exemplarily, when the two ends of the scraper are respectively slidably connected to the two sides of the upper side wall of the box body, the processor simultaneously drives the drive motors corresponding to the two ends of the scraper to start, so as to synchronously drive the two ends of the scraper to move, thereby driving the scraper to slide along the upper side wall of the box body. When one end of the scraper is rotationally connected to the upper side wall of the box body, the processor drives the drive motor at the connection end of the scraper to start, so as to drive the scraper to perform a circular motion along its connection end.

[0081] Combination Fig.11 As shown, in some other embodiments, a control method for a refrigerator includes:

[0082] S01, the processor obtains a cleaning instruction for the upper side wall of the refrigerator body;

[0083] S02, the processor controls the refrigeration module to start cooling the upper wall of the refrigerator;

[0084] S04, the processor obtains the opening time of the cooling module;

[0085] S05, the processor determines that the start-up time is greater than or equal to the set time;

[0086] S03, the processor controls the scraper to move to scrape pollutants on the upper wall of the refrigerator.

[0087] When the control method for a refrigerator provided by the embodiment of the present disclosure is used, when the refrigeration module is controlled to refrigerate the upper side wall of the cabinet, since the temperature of the upper side wall of the cabinet gradually decreases, it takes a certain amount of time for condensed water to be generated. After the condensed water is generated, it takes a certain amount of time to soak the pollutants on the upper side wall of the cabinet so that the pollutants can be better separated from the upper side wall of the cabinet. Therefore, the processor obtains the opening time of the refrigeration module, and only controls the scraper to move to scrape off the pollutants on the upper side wall of the cabinet after determining that the opening time is greater than or equal to the set time, thereby further improving the cleaning effect of the upper side wall of the cabinet.

[0088] Optionally, the set duration may be 20 minutes.

[0089] Optionally, the refrigeration module includes an evaporating coil, the evaporating coil is connected to the refrigeration system of the refrigerator, and the processor controls the refrigeration module to turn on to refrigerate the upper side wall of the refrigerator, including: the processor controls the refrigerant in the refrigeration system of the refrigerator to flow to the evaporating coil. In this way, when the refrigeration module is an evaporating coil, since the evaporating coil is connected to the refrigeration system of the refrigerator, when the processor needs to control the refrigeration module to turn on to refrigerate the upper side wall of the refrigerator, it is necessary to control the refrigerant to flow into the evaporating coil for evaporation and heat absorption, so the processor controls the refrigerant in the refrigeration system to flow to the evaporating coil.

[0090] Optionally, the processor controls the refrigerant in the refrigeration system of the refrigerator to flow to the evaporation coil, including: the processor controls the solenoid valves at both ends of the evaporation coil to open. In this way, since the evaporation coil is connected between the input end of the compressor of the refrigeration system and the output end of the condenser, the solenoid valves are arranged at both ends of the evaporation coil, so the processor controls the solenoid valves at both ends of the evaporation coil to open, so that the refrigerant in the refrigeration system flows to the evaporation coil.

[0091] Optionally, after the processor controls the electromagnetic valves at both ends of the evaporation coil to open, the method further includes: the processor obtains the relative humidity of the environment in which the refrigerator is located; and the processor controls the opening of the electromagnetic valves at both ends of the evaporation coil according to the relative humidity. In this way, the ability of the upper side wall of the cabinet to condense condensed water is related to the relative humidity in the environment. Therefore, the processor controls the opening of the electromagnetic valves at both ends of the evaporation coil according to the relative humidity, thereby ensuring that the upper side wall of the cabinet can efficiently condense condensed water while reducing energy consumption.

[0092] It can be understood that when the processor controls the solenoid valves at both ends of the evaporation coil to be opened, the opening of the solenoid valves is opened to the maximum opening by default.

[0093] Optionally, the processor controls the opening of the solenoid valves at both ends of the evaporation coil according to the relative humidity, including: when the relative humidity is greater than or equal to the first set value, the processor controls the opening of the solenoid valves at both ends of the evaporation coil to decrease; when the relative humidity is less than the first set value, the processor controls the opening of the solenoid valves at both ends of the evaporation coil to remain unchanged. In this way, when the relative humidity in the environment is high, the refrigeration demand of the upper side wall of the box is relatively small, and when the relative humidity in the environment is low, the upper side wall of the box needs to be lowered to a lower temperature to quickly condense condensed water, so the refrigeration demand of the upper side wall of the box is relatively large. Therefore, when the relative humidity is greater than or equal to the first set value, the opening of the solenoid valve is controlled to decrease, reducing the amount of refrigerant diverted by the refrigeration system to the evaporation coil, and reducing energy consumption. When the relative humidity is less than the first set value, the opening of the solenoid valve is controlled to remain unchanged, ensuring the refrigeration effect of the upper side wall of the box and efficiently condensing condensed water.

[0094] Specifically, the processor controls the opening of the solenoid valves at both ends of the evaporation coil to decrease to a set opening value, wherein the set opening value is smaller than the maximum opening value of the solenoid valve.

[0095] Optionally, while the processor controls the refrigerant in the refrigeration system of the refrigerator to flow to the evaporation coil, the processor also controls the operating frequency of the refrigerator compressor to increase. In this way, when the refrigerant in the refrigeration system is diverted to the evaporation coil, the amount of refrigerant flowing to the refrigerator evaporator is reduced, and in order to ensure the refrigeration effect of the refrigerator, the operating frequency of the compressor is controlled to increase.

[0096] Optionally, the processor controls the operating frequency of the refrigerator compressor to increase, including: the processor controls the operating frequency of the refrigerator compressor to increase by the first set frequency value when the relative humidity is greater than or equal to the first set value; the processor controls the operating frequency of the refrigerator compressor to increase by the second set frequency value when the relative humidity is less than the first set value, wherein the second set frequency value is greater than the first set frequency value. In this way, when the relative humidity is greater than or equal to the first set value, the relative humidity of the environment is high, the opening of the solenoid valves at both ends of the evaporating coil is relatively small, and the amount of refrigerant flowing to the evaporating coil in the refrigeration system is relatively small, so the operating frequency of the compressor is controlled to increase by the relatively small first set frequency value to reduce energy consumption. When the relative humidity is less than the first set value, the relative humidity of the environment is low, the opening of the solenoid valves at both ends of the evaporating coil is relatively large, and the amount of refrigerant flowing to the evaporating coil in the refrigeration system is relatively large, so the operating frequency of the compressor is controlled to increase by the relatively large second set frequency value, so as to ensure the refrigeration effect of the evaporating coil on the upper side wall of the cabinet while ensuring the refrigeration effect of the refrigerator.

[0097] Optionally, after the processor controls the scraper to move to scrape the pollutants on the upper side wall of the refrigerator, the process further includes: the processor obtains the movement time of the scraper, and when the movement time reaches a set movement time, controls the scraper to stop moving and return to an initial position. In this way, when the movement time of the scraper reaches the set movement time, the purpose of cleaning the upper side wall of the refrigerator has been achieved, and the scraper is controlled to stop moving and return to the initial position.

[0098] Optionally, set the exercise duration to 5 minutes.

[0099] Optionally, while the processor controls the scraper to stop moving and return to the initial position, the processor also controls the operating frequency of the compressor to reduce a set frequency value. In this way, after the cleaning of the upper side wall of the refrigerator is completed, in order to reduce the energy consumption of the refrigerator, the operating frequency of the compressor is controlled to reduce the set frequency value so that the compressor returns to its original level.

[0100] It can be understood that when the compressor increases the first set frequency value, the compressor is controlled to reduce the first set frequency value; when the compressor increases the second set frequency value, the compressor is controlled to reduce the second set frequency value so that the operating frequency of the compressor returns to the original level.

[0101] Optionally, while the processor controls the scraper to stop moving and return to the initial position, the processor also controls the electromagnetic valves at both ends of the evaporating coil to close, so that the refrigerant in the refrigeration system no longer flows to the evaporating coil.

[0102] In one embodiment, the processor obtains the cleaning instruction of the upper side wall of the refrigerator body, including: the processor obtains the dirty area of ​​the upper side wall of the box body; the processor obtains the cleaning instruction when the dirty area of ​​the upper side wall of the box body is greater than or equal to a set area. In this way, the processor determines the timing of obtaining the cleaning instruction by obtaining the dirty area of ​​the upper side wall of the box body, and obtains the cleaning instruction when the dirty area of ​​the upper side wall of the box body is greater than or equal to the set area, thereby improving the accuracy of the timing of obtaining the cleaning instruction.

[0103] Optionally, a scanning module is provided on one side of the upper side wall of the box, and the processor obtains the dirt area of ​​the upper side wall of the box, including: the processor obtains the image of the upper side wall of the box sent by the scanning module, and analyzes the image to determine the dirt area of ​​the upper side wall of the box.

[0104] Optionally, the scanning module is a camera.

[0105] In another embodiment, the processor obtains a cleaning instruction for the upper side wall of the refrigerator body, including: the processor obtains a cleaning instruction for the upper side wall of the refrigerator body issued by a user. In this way, the user can judge the degree of dirtiness of the upper side wall of the refrigerator body by himself, and then issue a cleaning instruction, and the processor obtains the cleaning instruction to control the refrigerator to clean the upper side wall of the refrigerator body.

[0106] In a specific embodiment, the refrigerator includes a touch screen; the processor obtains a cleaning instruction for the upper side wall of the refrigerator body issued by a user, including: the processor obtains a cleaning instruction for the upper side wall of the refrigerator body issued by the user through the touch screen. In this way, the user can issue a cleaning instruction to the processor by operating the touch screen, which simplifies the process of issuing the cleaning instruction.

[0107] In another specific embodiment, the refrigerator includes a microphone; the processor obtains a cleaning instruction for the upper side wall of the refrigerator body issued by a user, including: the processor obtains voice information issued by the microphone, and analyzes the voice information to determine the cleaning instruction. In this way, the user can issue a voice message, and the processor obtains the voice message through the microphone, and analyzes the voice message to determine the cleaning instruction.
