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.

[0044] 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.

[0045] Combination Figure 1-8 As shown, in some embodiments, the refrigerator includes: a box body 200, a refrigeration module 300 and a vibration unit 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 vibration unit 400 is arranged at the side wall of the box body 200, and is used to drive the upper side wall of the box body 200 to vibrate.

[0046] The refrigerator and control method thereof provided by the embodiment of the present disclosure are adopted, by setting a refrigeration module 300 in the upper side wall area of ​​the box body 200, when it is necessary to clean the upper side wall of the box body 200, 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 vibration part 400 is used to emit vibration, thereby driving the upper side wall of the box body 200 to cause resonance, so that dust and other pollutants on the upper side wall of the box body 200 flow down with the condensed water, 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 vibration, thereby reducing the risk of pollution of the environment where the refrigerator is located and improving the user experience.

[0047] 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.

[0048] 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.

[0049] 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 is also convenient to set.

[0050] Optionally, there is an inclination angle between the upper side wall of the box body 200 and the horizontal plane, so that pollutants and condensed water can flow down along the upper side wall of the box body 200 under the action of vibration, thereby improving the cleaning effect of the upper side wall of the box body 200.

[0051] Optionally, the upper side wall of the box body 200 has an inclination angle of 5° with the horizontal plane. In this way, the upper side wall of the box body 200 has an inclination angle, so that the condensed water mixed with pollutants flows down naturally with the vibration, and the inclination of the upper side wall of the box body 200 is not easily noticed, thereby ensuring the appearance consistency of the box body 200.

[0052] Optionally, the upper side wall of the box body 200 is inclined in the direction from the front side to the rear side, so that the condensed water and pollutants on the upper side wall of the box body 200 can flow from the front side to the rear side, and the condensed water and pollutants are discharged to the rear, so as to prevent the pollutants from contaminating the door body 500 on the front side of the box body 200.

[0053] 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.

[0054] Combination Figure 1 and Figure 2As 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.

[0055] Optionally, 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, 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, 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.

[0056] 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.

[0057] Combination Figure 3As 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.

[0058] 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.

[0059] 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.

[0060] 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. There is a gap between the lower end of the refrigeration module 300 and the upper side wall of the box body 200 to prevent the refrigeration module 300 from blocking the condensed water and pollutants, and ensure that the condensed water and pollutants can flow down naturally along the upper side wall of the box body 200.

[0061] Alternatively, if 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 vibration of the vibration part 400 drives the upper side wall of the box body 200 to resonate, so that the condensed water and dust and other pollutants on the upper side wall of the box body 200 flow into the water collecting groove 240 along the upper side wall of the box body 200, and then are discharged through the sewage pipe 250, without the need to set up an additional sewage discharge structure, reducing costs and improving user experience.

[0062] Optionally, a water collecting groove 240 is provided at the rear side of the upper side wall of the box body 200. In this way, since the upper side wall of the box body 200 is inclined from the front side to the rear side, condensed water and pollutants flow toward the rear side of the upper side wall of the box body 200 under the action of vibration, and therefore, a water collecting groove 240 is provided at the rear side of the upper side wall of the box body 200, so that condensed water and pollutants flow into the water collecting groove 240.

[0063] Optionally, water collecting grooves 240 are provided at other sides of the upper side wall of the box body 200 except the front side, and adjacent water collecting grooves 240 are connected. In this way, when the upper side wall of the box body 200 vibrates with the vibration part 400, condensed water carrying pollutants may also flow to the two side positions adjacent to the rear side. Therefore, water collecting grooves 240 are provided at other sides of the upper side wall of the box body 200 except the front side, and adjacent water collecting grooves 240 are connected, so that condensed water and pollutants can be better collected.

[0064] Optionally, the bottom end of each water collecting tank 240 is connected to the sewage pipe 250. In this way, the condensed water and pollutants in each water collecting tank 240 can be discharged through the sewage pipe 250.

[0065] 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. The drain pipe 250 is arranged vertically so that the condensed water and pollutants can quickly flow into the dirt storage pan under the action of gravity.

[0066] Optionally, the dirt storage tray may be a water collection tray of a refrigerator.

[0067] Alternatively, if Figure 5 and Figure 8As shown, the vibration part 400 is disposed on the upper side wall of the box body 200. In this way, the vibration generated by the vibration part 400 can be more efficiently transmitted to the upper side wall of the box body 200, thereby better driving the upper side wall of the box body 200 to vibrate, so that dust and other pollutants on the upper side wall of the box body 200 are better separated from the upper side wall of the box body 200, thereby improving the cleaning effect of the upper side wall of the box body 200.

[0068] Optionally, the vibration part 400 is disposed below the upper side wall of the box body 200 and abuts against the upper inner wall of the box body 200. In this way, the vibration part 400 can be hidden below the upper side wall of the box body 200 to prevent the vibration part 400 from blocking the flow of condensed water and pollutants.

[0069] Optionally, a plurality of vibration parts 400 are provided, and the plurality of vibration parts 400 are respectively located at the corner regions of the upper side wall of the box body 200. In this way, by providing a plurality of vibration parts 400, and respectively provided at the corner regions of the upper side wall of the box body 200, the plurality of vibration parts 400 vibrate together to drive the upper side wall of the box body 200 to vibrate, thereby improving the uniformity of the vibration of the upper side wall of the box body 200, and further improving the cleaning effect of the upper side wall of the box body 200.

[0070] Specifically, four vibration parts 400 are provided, and the four vibration parts 400 are respectively located at four corner areas of the upper side wall of the box body 200 .

[0071] Optionally, the vibration part 400 is a vibration motor or an ultrasonic oscillator.

[0072] Combination Fig. 9 As shown, in some embodiments, a method for controlling a refrigerator includes:

[0073] S01, the processor obtains a cleaning instruction for the upper side wall of the refrigerator body;

[0074] S02, the processor controls the refrigeration module to start cooling the upper wall of the refrigerator;

[0075] S03, the processor controls the vibration part to start and drive the upper side wall of the box to vibrate, so that the condensed water and pollutants flow down along the upper side wall of the box.

[0076] The control method of the refrigerator provided in the embodiment of the present disclosure is adopted to determine the cleaning time of the refrigerator by obtaining the cleaning instruction of the refrigerator. When the cleaning instruction is obtained, the refrigeration module is controlled to start cooling the upper side wall of the cabinet so that condensed water can condense on the upper side wall of the cabinet, and then the vibration part is controlled to start to drive the upper side wall of the cabinet to vibrate, so that the cleaning of the refrigerator is more intelligent.

[0077] Combination Fig.10 As shown, in some other embodiments, a method for controlling a refrigerator includes:

[0078] S01, the processor obtains a cleaning instruction for the upper side wall of the refrigerator body;

[0079] S02, the processor controls the refrigeration module to start cooling the upper wall of the refrigerator;

[0080] S04, the processor obtains the opening time of the cooling module;

[0081] S05, the processor determines that the start-up time is greater than or equal to the set time;

[0082] S03, the processor controls the vibration part to start and drive the upper side wall of the box to vibrate, so that the condensed water and pollutants flow down along the upper side wall of the box.

[0083] According to the control method of the refrigerator provided by the embodiment of the present disclosure, 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 vibrator to vibrate to drive the resonance of the upper side wall of the cabinet after determining that the opening time is greater than or equal to the set time, which can reduce the generation of dust and further improve the cleaning effect of the upper side wall of the cabinet.

[0084] Optionally, the set duration may be 20 minutes.

[0085] 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.

[0086] 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.

[0087] 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.

[0088] 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.

[0089] 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.

[0090] 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.

[0091] 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.

[0092] 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.

[0093] Optionally, after the processor controls the vibration part to start and drive the upper side wall of the box body to vibrate, the method further includes: the processor obtains the start-up time of the vibration part, and controls the vibration part to be turned off when the start-up time reaches the set start-up time. In this way, when the start-up time of the vibration part reaches the set start-up time, the cleaning purpose of the upper side wall of the box body has been achieved, and the vibration part is controlled to be turned off.

[0094] Optionally, set the on time to 8 minutes.

[0095] Optionally, while the processor controls the vibration part to be turned off, 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 cabinet 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.

[0096] 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.

[0097] Optionally, while the processor controls the vibration part to be turned off, the processor also controls the electromagnetic valves at both ends of the evaporation coil to be turned off, so that the refrigerant in the refrigeration system is no longer diverted to the evaporation coil.

[0098] Optionally, 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.

[0099] 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.

[0100] 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.

[0101] In some embodiments, the processor controls the vibration part to start and drive the upper side wall of the box body to vibrate, including: the processor obtains the operating state of the refrigerator compressor; when the compressor is in the operating state, the processor controls the vibration part to start and drive the upper side wall of the box body to vibrate; when the compressor is in the standby state, the processor obtains the operating time of the compressor, and controls the vibration part to start and drive the upper side wall of the box body to vibrate when the compressor is running. In this way, since the vibration part will drive the box body to resonate and generate noise when it is turned on, and the compressor will also vibrate when it is running and drive the box body to resonate and generate noise. Therefore, the processor controls the vibration part to start and vibrate with the compressor when the compressor is running, so that the vibration of the vibration part coincides with the operating time of the compressor, and the time when the refrigerator makes noise is reduced as much as possible, thereby reducing the impact of the noise generated by the cleaning of the upper side wall of the box body on the indoor environment and improving the user experience.
