If it is described as first, second, it is only for the purpose of distinguishing technical features, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of indicated technical features or implicitly indicating the order of indicated technical features.

[0043] In the description of the present application, unless otherwise explicitly limited, the words such as setting, mounting, connecting, assembling, cooperating, etc. should be understood in a broad sense, and those skilled in the art can reasonably determine the specific meaning of the above words in the present application in combination with the specific content of the technical solution.

[0044] The main refrigeration method of the current refrigerator is air cooling, that is, air is used for refrigeration. When high-temperature air flows through the built-in evaporator (the evaporator is separated from the inner wall of the refrigerator), due to the high temperature of the air and the low temperature of the evaporator, heat exchange occurs directly between the two, the temperature of the air will be reduced, and the obtained cold air is blown into the refrigerator. Through this continuous circulation method, the temperature of the refrigerator is reduced. Air-cooled refrigerators are widely used due to their advantages of no frost, circulating air to keep the smell fresh inside the refrigerator, etc.

[0045] However, air-cooled refrigerators are prone to cause the humidity of the freezer compartment 110 to be too low due to direct blowing of the air supply, especially when the cold air is directly blown towards the food materials in the freezer compartment 110, which can easily cause the food materials to lose moisture quickly, especially the surface of the food materials to lose water severely, dry consumption is serious, oxidation is intensified, for frozen meat food materials, it is easy to form DFD meat (i.e. dry muscle, coarse texture, dark meat) or PSE meat (i.e. white meat, soft meat, with exudate); for food materials, it is easy to crack; for aquatic food materials, it is easy to cause oxidation to be intensified; for fruit food materials, it is easy to cause dryness and browning; which seriously affects the taste of the food materials and causes serious loss of nutrients.

[0046] To solve the problem of excessive loss of nutrients caused by excessive loss of water, some achieve moisture retention by changing the direction of cold air outlet, increasing the cover plate 160, etc., to reduce water loss, but do not increase the humidity of the food, and the effect is not good. Some use the method of coating ice clothes on the surface of the food. In the related art, the coating of ice clothes is achieved by spraying water combined with drainage. The overall design of the drainage structure is complex. In order to prevent the drainage structure from icing, a sensor and a heating device are added, which is relatively high in cost and is not conducive to application.

[0047] To solve the above problems, with reference to Figure 1 and Figure 2 , the first aspect of the present application provides a refrigerator, which can be a single-door refrigerator, a double-door wall cabinet refrigerator, a three-door refrigerator, etc., and the refrigerator is a wind-cooled refrigerator, i.e. the temperature of the refrigerator is lowered by circulating cold air. The refrigerator comprises a cabinet 100, an atomizing device 200 and a first fan 300.

[0048] With reference to Figure 1 , it can be understood that the cabinet 100 is a vertical cabinet structure, and the cabinet 100 has an inner cavity opening forward, which is divided into a refrigeration compartment 120 and a freezing compartment 110. The refrigeration compartment 120 is located on the upper side, and the freezing compartment 110 is located on the lower side. Of course, the positions of the refrigeration compartment 120 and the freezing compartment 110 can be interchanged. The cabinet 100 is also provided with a cabinet door (not shown in the figure) for closing the refrigeration compartment 120 and the freezing compartment 110. The cabinet door can be provided on the refrigeration compartment 120 and the freezing compartment 110 respectively, or a cabinet door is provided to close the refrigeration compartment 120 and the freezing compartment 110 at the same time. The temperature of the refrigeration compartment 120 is generally greater than 0℃ and will not freeze, and the temperature of the freezing compartment 110 is generally lower than 0℃ and will freeze. A foaming layer 130 is provided between the refrigeration compartment 120 and the freezing compartment 110. The foaming layer 130 can be polyurethane foam and has a heat preservation effect, which plays a role of heat insulation between the refrigeration compartment 120 and the freezing compartment 110, avoiding the transfer of cold and heat between the refrigeration compartment 120 and the freezing compartment 110.

[0049] With reference to Figure 1 and Figure 2It can be understood that a plurality of first bearing components 150 are arranged in the freezing compartment 110, the plurality of first bearing components 150 can be arranged side by side in the left-right direction or arranged in sequence in the vertical direction, the first bearing component 150 is used for placing food materials, and the first bearing component 150 can be a partition plate, a drawer or the like, so as to facilitate the classification and placement of a plurality of food materials, and the space utilization of the freezing compartment 110 can be improved. Among them, the first bearing component 150 located at the uppermost side can be a partition plate or a drawer, when the first bearing component 150 at the uppermost side is a partition plate, the space above the partition plate is the ice-coated space 111; when the first bearing component 150 at the uppermost side is a drawer, the internal space of the drawer is the ice-coated space 111. The ice-coated space 111 is used for coating ice on the food materials placed therein, so as to humidify and preserve the food materials, and avoid the problem of serious water loss and nutrient loss of the food materials caused by direct blowing of cold air.

[0050] With reference to Figure 1 And Figure 2 It can be understood that the atomizing device 200 is arranged in the cabinet 100, and the atomizing device 200 can be arranged in the refrigerating compartment 120, the freezing compartment 110 or the outside of the cabinet 100. When the atomizing device 200 is arranged in the freezing compartment 110, a heating device needs to be used in cooperation to prevent the water in the atomizing device 200 from freezing, so as to avoid damage of the atomizing device 200 due to freezing. The atomizing device 200 comprises a shell 210, the shell 210 is divided into a water storage cavity 220 and an atomizing cavity 230, the water storage cavity 220 and the atomizing cavity 230 are respectively located at two sides of the shell 210, and the shell 210 is provided with a water inlet 211 at the top, the water inlet 211 is communicated with the water storage cavity 220, and water is injected into the water storage cavity 220 through the water inlet 211, so as to generate mist. The mist here is fine water droplets that can be suspended in the air. The shell 210 is further provided with a flow guide plate 212 connected to the water inlet 211, the flow guide plate 212 is arranged obliquely downward, so as to guide the water to flow into the water storage cavity 220, avoid water overflow when water is injected into the water storage cavity 220, and facilitate water injection.

[0051] With reference to Figure 1 And Figure 2 It can be understood that the atomizing cavity 230 of the atomizing device 200 is communicated with the ice-coated space 111 of the freezing compartment 110. For example, when the atomizing device 200 is arranged in the refrigerating compartment 120 or the outside of the cabinet 100, the atomizing cavity 230 can be communicated with the ice-coated space 111 of the freezing compartment 110 through a pipeline; when the atomizing device 200 is arranged in the freezing compartment 110, generally, the atomizing device 200 is located at the top of the freezing compartment 110, and then a wall of the atomizing cavity 230 is provided with a mist outlet 231 communicated with the ice-coated space 111 of the freezing compartment 110, so that the mist in the atomizing cavity 230 can enter the ice-coated space 111.

[0052] With reference to Figure 2It can be understood that the atomization device 200 further comprises an ultrasonic atomization element located in the water storage cavity 220 and used to generate the mist, the ultrasonic atomization element comprising an ultrasonic vibrator 221 and a control circuit board 222, the ultrasonic vibrator 221 being electrically connected with the control circuit board 222, the control circuit board 222 being electrically connected with a controller (not shown in the figure) of the refrigerator, the ultrasonic vibrator 221 being fixedly installed on the bottom wall of the water storage cavity 220, the mist being formed by controlling the vibration of the ultrasonic vibrator 221, and the mist being formed above the water surface. A through hole (not shown in the figure) is formed above the wall body between the atomization cavity 230 and the water storage cavity 220, the through hole being used for allowing the mist to pass through so as to allow the mist to enter the atomization cavity 230, thereby the food can be further coated with ice by the mist in the atomization cavity 230. The ultrasonic atomization has the advantages of large mist output, fast mist diffusion, fine mist particles and the like, and the mist forming effect is better. Of course, the ultrasonic vibrator 221 can also be arranged on the side wall of the water storage cavity 220, and it is required to ensure that the ultrasonic vibrator 221 is immersed in the water, that is, the ultrasonic vibrator 221 is below the water surface, and the mist can also be generated by vibration, and the installation position of the ultrasonic vibrator 221 is not limited here.

[0053] It can be understood that the atomization device 200 can also generate the mist by a pressure atomization mode, for example, the water is pressurized by a pressure type atomization nozzle, and then the mist is formed.

[0054] It can be understood that the preservative can also be added into the water through the water injection port 211, so as to form the mist with the preservative, and when the mist is applied to coat the ice on the food, the preservation effect on the food can be further improved, and the loss of nutrients of the food can be avoided.

[0055] Referring to Figure 2 It can be understood that the bottom wall of the water storage cavity 220 is further provided with a heat dissipation plate 223, heat is inevitably generated during the working process of the ultrasonic atomization element, too much heat affects the normal working of the ultrasonic atomization element on the one hand, and affects the atomization of the water on the other hand, the heat dissipation plate 223 can conduct the heat generated by the ultrasonic atomization element, the heat dissipation area is increased, so as to dissipate the heat of the ultrasonic atomization device 200, and the atomization reliability is improved.

[0056] Referring to Figure 2It can be understood that the first fan 300 is installed in the atomizing cavity 230, for example, the first fan 300 is installed at the mist outlet 231 of the atomizing cavity 230, or the first fan 300 is installed in the connecting pipeline between the atomizing cavity 230 and the ice-coated space 111, or the first fan 300 is installed on the inner wall of the atomizing cavity 230 away from the mist outlet 231. When the first fan 300 is installed at the mist outlet 231 or the connecting pipeline, the air inlet end of the first fan 300 faces the atomizing cavity 230, and when the first fan 300 is installed on the inner wall away from the mist outlet 231, the air outlet end of the first fan 300 faces the storage mist outlet 231, so that the mist output rate can be accelerated by the first fan 300, and the mist can be concentrated and blown to the food placed in the ice-coated space 111 and attached to the outer surface of the food, thereby humidifying the food. At the same time, under the freezing environment of the freezing compartment 110, the mist attached to the outer surface of the food forms ice, thereby preserving the food. By setting the first fan 300 to output mist, the mist output rate can be accelerated, the ice-coating efficiency can be effectively improved, and the ice-coating effect can be improved.

[0057] The food is placed in the ice-coated space 111 of the freezing compartment 110, the ultrasonic vibrator 221 of the atomizing device 200 vibrates to convert the water in the water storage cavity 220 into mist, the mist enters and is stored in the atomizing cavity 230 through the through hole, the first fan 300 is started, and the first fan 300 blows the mist in the atomizing cavity 230 to the food in the ice-coated space 111, the mist is attached to the surface of the food, the food is humidified, and at the same time, under the freezing environment of the freezing compartment 110, the mist attached to the surface of the food freezes, thereby forming an ice coat on the surface of the food, preserving the food, and the overall structure is simple, without the need to set a drainage mechanism, effectively reducing the cost, and the ice-coating effect is good, so that the food can maintain the original color and flavor for a long time, avoiding the problems of serious water loss and nutrient loss.

[0058] Referring to Figure 2 It can be understood that the wall between the water storage cavity 220 and the atomizing cavity 230 is also provided with a second fan 240, the second fan 240 is installed at the through hole, the air inlet end of the second fan 240 faces the water storage cavity 220, and the air outlet end of the second fan 240 faces the atomizing cavity 230. The mist generated by the ultrasonic vibrator 221 of the water storage cavity 220 is sucked into the atomizing cavity 230 through the second fan 240 for storage, so that the mist in the water storage cavity 220 can be timely sucked away, the pressure of the mist in the water storage cavity 220 is prevented from being too large to affect the mist manufacturing process, the rate of the mist entering the atomizing cavity 230 can be accelerated, and the output mist rate and the ice-coating efficiency can be improved.

[0059] Referring to Figure 1 and Figure 2It can be understood that the atomizing device 200 is installed on the lower side of the refrigeration compartment 120, which can effectively avoid the water in the atomizing device 200 from freezing and affecting the production of mist, and avoid the damage of the ultrasonic element caused by freezing. The atomizing device 200 does not need to be matched with a heating device to prevent water from freezing, and has a simple structure and low cost. Generally, the refrigeration compartment 120 is also provided with a plurality of second bearing parts 170, which can be arranged side by side along the left-right direction or sequentially from top to bottom. The second bearing part 170 can be a partition plate or a drawer for storing food, thereby improving the space utilization rate of the refrigeration compartment 120. The atomizing device 200 is located on the left side of the lowermost second bearing part 170, so that the atomizing device 200 does not affect the normal storage function of the second bearing part 170, and the installation structure of the atomizing device 200 is compact.

[0060] Referring to Figure 1 and Figure 2 It can be understood that the bottom wall of the atomizing cavity 230 is provided with a mist outlet 231, and the mist outlet 231 is connected with the freezing compartment 110 through a mist conveying pipe 232. One end of the mist conveying pipe 232 connected to the freezing compartment 110 is located above the ice-coated space 111, so that the atomizing cavity 230 is communicated with the ice-coated space 111. The mist conveying pipe 232 is arranged in the foaming layer 130, so that the foaming layer 130 protects the mist conveying pipe 232 from being damaged by collision, prolongs the service life of the mist conveying pipe 232, and improves the reliability. The diameter of the mist conveying pipe 232 is set according to the demand for mist output. For example, if the demand for mist output is large, a mist conveying pipe 232 with a larger diameter is selected, and if the demand for mist output is small, a mist conveying pipe 232 with a smaller diameter is selected.

[0061] Referring to Figure 1 and Figure 2 It can be understood that since the temperature of one end of the mist conveying pipe 232 connected to the freezing compartment 110 is low, the mist is easy to freeze and form granular ice beads at the end of the mist conveying pipe 232 connected to the freezing compartment 110. When the mist is sprayed to the food in the ice-coated space 111 through the mist conveying pipe 232, the granular ice beads cannot be attached to the surface of the food, so that the food cannot be humidified, and the generation of ice-coated clothes is affected, and even the mist conveying pipe 232 can be blocked. Therefore, a first heating element 233 is arranged at the end of the mist conveying pipe 232 connected to the freezing compartment 110. The first heating element 233 can be a heating wire, a heating film or the like. The first heating element 233 can heat the end of the mist conveying pipe 232, so that the mist maintains a temperature above 0℃ and keeps a misty shape when passing through the mist conveying pipe 232, thereby avoiding the mist from freezing to form ice beads, so that the mist can be attached to the surface of the food to humidify the food, and the problem of blocking the mist conveying pipe 232 caused by freezing is avoided. At the same time, the mist attached to the surface of the food can form ice-coated clothes, thereby ensuring the reliability of the ice-coated clothes, achieving food preservation, and avoiding the problems of serious water loss and nutrient loss of the food.

[0062] With reference to Figure 1 And Figure 2 It can be understood that, for the air-cooled refrigerator, the freezing compartment 110 is provided with an air duct opening 140 for circulating and blowing out cold air to reduce the temperature of the freezing compartment 110 and achieve the freezing effect. Since the fog is fine water droplets that are densely spaced and can be suspended in the air, when the fog is sprayed onto the surface of the food, the fog instantly becomes frost in the freezing environment of the freezing compartment 110, and the frost is small ice beads that are densely spaced and cannot completely cover the food, i.e., the ice coat is not completely formed. Therefore, the second heating element 141 is arranged at the air duct opening 140, which can be a heating wire, a heating film or the like, and the second heating element 141 can heat the air blown out by the air duct opening 140. In specific applications, after the fog adheres to the surface of the food and forms frost, the second heating element 141 works, the air duct opening 140 briefly blows out hot air to melt the frost adhering to the surface of the food to form a water film, the second heating element 141 stops working, and the air duct opening 140 continues to blow out cold air, so that the water film on the surface of the food forms an ice film, and the ice film can completely cover the food, i.e., the ice film is more completely formed, so that the ice coat can preserve the food, effectively avoiding the problems of severe water loss and nutrient loss of the food.

[0063] With reference to Figures 3 to 5It can be understood that the first bearing component 150 at the uppermost side of the freezing chamber 110 is arranged as a drawer, facilitating the pulling and storage of food materials.

The positions of the first partition plate 151 and the second partition plate 152 can be adjusted according to the size of the volume of the food materials, that is, the size of the cavity 1522 is adjusted. The specific operation is to sequentially pull out the second partition plate 152 and the first partition plate 151, adjust the positions of the first mounting slot 1533 and the second mounting slot 1543, and then sequentially insert the first partition plate 151 and the second partition plate 152. When the volume of the food materials is small, the size of the cavity 1522 can be reduced, so that the size of the cavity 1522 matches the food materials, the spraying range of the mist is limited within the volume range of the food materials, so that the mist can be concentrated to the food materials, and then the ice-coated clothing is more complete, the ice-coated clothing covers the food materials better, which is beneficial to the preservation of the food materials, and effectively avoids the problems of serious water loss and nutrient loss of the food materials.

[0065] Referring to Figure 1 , Figure 2 and Figure 6It can be understood that the top of the drawer located at the uppermost part of the freezing chamber 110 is provided with a cover plate 160, that is, the cover plate 160 is installed above the icing space 111, the cover plate 160 is provided with a plurality of mist outlets 161, the plurality of mist outlets 161 are uniformly distributed on the cover plate 160, one end of the mist conveying pipe 232 connected to the freezing chamber 110 is located above the cover plate 160, and the end of the mist conveying pipe 232 faces the cover plate 160, so that the mist output from the mist conveying pipe 232 can be uniformly sprayed to the icing space 111 through the mist outlets 161 uniformly distributed on the cover plate 160, which is beneficial to the attachment of the mist on the food to form the ice clothes. At this time, cooperating with the size-adjustable chamber 1522, the mist sprayed from the mist outlets 161 above the chamber 1522 can be concentratedly sprayed to the food stored in the chamber 1522, which is beneficial to the formation of complete ice clothes to completely cover the food.

[0066] In the specific application of the ice-coated clothes function, the food is stored in the icing space 111 of the freezing chamber 110, the positions of the first partition plate 151 and the second partition plate 152 are adjusted according to the size of the volume of the food, the size of the chamber 1522 is matched with the volume of the food, the ultrasonic vibrator 221, the first fan 300 and the second fan 240 are started, at this time, the air duct opening 140 stops air supply, the water in the water storage cavity 220 is converted into mist by the vibration of the ultrasonic vibrator 221, the mist is sucked into the atomizing cavity 230 by the second fan 240 through the through hole, the mist in the atomizing cavity 230 is blown to the icing space 111 by the first fan 300 through the mist conveying pipe 232, in order to prevent the mist blown out of the mist conveying pipe 232 from being frozen and causing the blockage of the mist conveying pipe 232, the first heating element 233 is started to heat the mist conveying pipe 232, the mist blown out of the mist conveying pipe 232 is uniformly attached to the surface of the food in the chamber 1522 through the mist outlets 161 on the cover plate 160, and the food is humidified, in the freezing environment of the freezing chamber 110, the mist attached to the surface of the food instantly becomes frost, and the frost is densely and intermittently distributed small ice beads, at this time, the second heating element 141 is started and the air duct opening 140 re-supplies air, the air duct opening 140 temporarily blows out hot air to melt the frost attached to the surface of the food to form a water film, the second heating element 141 stops working, and the air duct opening 140 continues to blow out cold air, so that the water film on the surface of the food forms an ice film, the ice film completely covers the food, that is, the ice-coated clothes on the surface of the food is completed, the food is preserved, the overall structure is simple, a drainage mechanism does not need to be additionally arranged, the cost is effectively reduced, and the ice-coated clothes effect is good, so that the food can keep the original color and flavor for a long time, and the problems of serious water loss and nutrient loss are avoided.

[0067] Referring to Figure 9 The second aspect embodiment of the present application provides an ice-coated clothes control method of a refrigerator, and the ice-coated clothes control method of the refrigerator comprises the following steps:

[0068] Step S100: obtaining a starting instruction of an ice-coated clothes mode;

[0069] The starting instruction of the ice-coating mode can be issued by a user through operating the control panel, the button, the remote control, or other control components of the refrigerator according to the requirement, and the controller (not shown in the figure) of the refrigerator can obtain the starting instruction of the ice-coating mode issued by the user.

[0070] Alternatively, the starting instruction of the ice-coating mode can also be issued by detecting that the food material is stored in the ice-coating space 111, for example, a weighing instrument (not shown in the figure) is arranged at the bottom of the ice-coating space 111 to detect the weight of the stored food material, the weighing instrument is electrically connected with the controller, if the detected weight is greater than zero, it indicates that the food material is stored in the ice-coating space 111, and the signal is fed back to the controller, that is, the starting instruction of the ice-coating mode is issued to the controller; or an infrared detector is used to detect whether the food material exists in the ice-coating space 111, the infrared detector is electrically connected with the controller, if the infrared detector detects that the food material exists in the ice-coating space 111, the signal is also fed back to the controller, that is, the starting instruction of the ice-coating mode is issued to the controller; so that the controller can obtain the starting instruction of the ice-coating mode issued by the detecting element.

[0071] Alternatively, the starting instruction of the ice-coating mode can be issued by combining the above two ways, that is, when the user issues the first starting instruction of the ice-coating mode through operating the control panel, the button, the remote control, or other control components of the refrigerator, and the detecting element detects that the food material exists in the ice-coating space 111 and issues the second starting instruction of the ice-coating mode, the controller can truly obtain the starting instruction of the ice-coating mode, so as to avoid misoperation. The way of issuing the ice-coating instruction is not limited here.

[0072] Step S200: starting the atomizing device and the first fan according to the starting instruction.

[0073] When the controller obtains the starting instruction of the ice-coating mode, the ultrasonic vibrator 221, the first fan 300, and the second fan 240 are started, the ultrasonic vibrator 221 vibrates to convert the water in the water storage cavity 220 into mist, the mist enters and is stored in the atomizing cavity 230 through the through hole, the first fan 300 is started to blow the mist in the atomizing cavity 230 to the food material in the ice-coating space 111, the mist adheres to the surface of the food material, the mist adhering to the surface of the food material forms ice coat under the frozen environment of the freezing compartment 110, so that a layer of ice coat is coated on the surface of the food material, the food material is preserved, the control mode is simple, the ice-coating effect is good, the food material can keep the original color and flavor for a long time, and the problems of serious water loss and nutrient loss are avoided.

[0074] With reference to Figure 2 and Figure 9 It can be understood that before the step of starting the atomizing device and the first fan according to the starting instruction, the following step is further included:

[0075] Step S110: Obtain the water level height value of the water storage cavity, and determine whether the water level height value is within the preset water level value range;

[0076] The inner wall of the water storage cavity 220 is provided with a liquid level sensor 224, which is electrically connected with the controller. The liquid level sensor 224 is used to detect the water level height value in the water storage cavity 220, so that the controller can obtain the water level height value in the water storage cavity 220 for the next step control. Generally, a preset water level value range can be set in the program of the controller according to the actual size of the water storage cavity 220, to limit the lower limit value and the upper limit value of the water level height value, so as to determine whether the water storage amount in the water storage cavity 220 meets the ice coating plating requirement.

[0077] It can be understood that the inner wall of the water storage cavity 220 is sequentially provided with a water level lower limit value scale line 225 and a water level upper limit value scale line 226 from bottom to top, which facilitates the user to inject the appropriate amount of water into the water storage cavity 220 when injecting water, and avoids that too much water causes the water to overflow the through hole between the water storage cavity 220 and the atomization cavity 230, affecting the normal manufacturing process of the mist.

[0078] When the water level height value is within the preset water level value range, step S101 is performed according to the start instruction to start the atomization device 200 and the first fan 300.

[0079] After the controller obtains the start instruction of the ice coating plating mode, the liquid level sensor 224 detects that the water level height value in the water storage cavity 220 is within the preset water level value range, the controller normally controls the ultrasonic vibrator 221, the first fan 300 and the second fan 240 to work, and performs the ice coating plating mode to realize the ice coating plating on the surface of the food material, and realizes the preservation of the food material.

[0080] When the water level height value exceeds the preset water level value range, step S111 is performed to issue a warning signal.

[0081] After the controller obtains the start instruction of the ice coating plating mode, the liquid level sensor 224 detects that the water level height value in the water storage cavity 220 exceeds the preset water level value range. For example, the water level height value is greater than the upper limit value of the water level height, which means that the water amount is too much, and the space above the water surface is too small, which is not conducive to the formation of the mist. The controller then issues a warning signal to remind the user to draw out part of the water. Or the water level height value is less than the lower limit value of the water level height, which means that the water amount is too small, which may be that the user adds too little water, or the last ice coating plating mode has basically used up the water in the water storage cavity 220, which is easy to cause that the ultrasonic vibrator 221 cannot manufacture the mist or the amount of the mist is too small, which is not conducive to the ice coating plating. The controller then issues a warning signal to remind the user to add water to the water storage cavity 220. The warning signal can include but is not limited to warning light, alarm sound, text prompt and combination thereof.

[0082] Referring toFigure 9 It can be understood that the ice coating control method further comprises the following steps:

[0083] Step S300: Close the air duct opening.

[0084] Before the ice coating mode is started, the air duct opening 140 normally blows out cold air to achieve the purpose of lowering the temperature of the freezing compartment 110 and achieving freezing. After the ice coating mode is started, i.e., after the ultrasonic vibrator 221, the first fan 300 and the second fan 240 are started, the controller controls to close the air duct opening 140 and stop blowing cold air into the freezing compartment 110, so as to avoid the cold air blown out of the air duct opening 140 from dispersing the mist sprayed by the mist delivery pipe 232 to the food, and ensure that the mist can normally adhere to the surface of the food, thereby forming an ice coat and improving reliability.

[0085] It can be understood that the order of starting the first fan 300 and closing the air duct opening 140 can be interchanged or performed simultaneously.

[0086] Referring to Figure 9 It can be understood that the ice coating control method further comprises the following steps:

[0087] Step S400: Start the first heating element.

[0088] After the ice coating mode is started, i.e., after the ultrasonic vibrator 221, the first fan 300 and the second fan 240 are started, the mist is sprayed out of the mist delivery pipe 232 to the ice coating space 111. Since the temperature of the freezing compartment 110 is low, in order to avoid the mist from icing when entering the freezing compartment 110 and failing to adhere to the food, the mist cannot humidify the food, and the formation of the ice coat is affected. Therefore, the controller controls the first heating element 233 arranged at one end of the mist delivery pipe 232 connected to the freezing compartment 110 to start, and then heats the mist delivery pipe 232, i.e., heats the output mist, so that the mist maintains a temperature above 0°C and keeps the mist in a misty state, so that the mist can adhere to the surface of the food, humidify the food, and facilitate the formation of the ice coat, thereby ensuring the reliability of the ice coating, preserving the food, and avoiding the problem of clogging of the mist delivery pipe 232 caused by icing of the mist.

[0089] Referring to Figure 9 It can be understood that the ice coating control method further comprises the following steps:

[0090] Step S500: Start the second heating element.

[0091] After the ice coating mode is started and the air duct opening 140 is closed, the controller controls the second heating element 141 located at the air duct opening 140 to start, and the second heating element 141 heats the air duct opening 140, i.e., preheats the cold air in the air duct opening 140.

[0092] It can be understood that the order of starting the first heating element 233 and starting the second heating element 141 can be interchanged or performed simultaneously.

[0093] Referring to Figure 9 It can be understood that the ice coating control method further comprises the following steps:

[0094] Step S600: When the first fan runs for a first preset time, the atomizing device and the first fan are turned off, and the air duct opening is opened.

[0095] After the ultrasonic vibrator 221, the first fan 300 and the second fan 240 are started, the mist is output from the mist conveying pipe 232 and sprayed to the food materials stored in the ice coating space 111. After the mist continues to spray for a first preset time, i.e., after the first fan 300 runs for a first preset time, the ultrasonic vibrator 221, the first fan 300 and the second fan 240 stop working. For example, the mist continues to spray (i.e., the first fan 300 runs) for 10 minutes or 15 minutes, etc. so that enough mist is attached to the surface of the food materials to increase the humidity of the food materials, and in the freezing environment of the freezing compartment 110, the mist attached to the surface of the food materials instantly becomes frost, thereby increasing the thickness of the frost. Since the frost is in the state of small ice beads distributed at close intervals at this time, it cannot form a complete ice coat. Therefore, the controller controls the air duct opening 140 to be opened, at this time, the air duct opening 140 blows hot air to melt the frost on the surface of the food materials into a water film, so as to form a complete ice film by subsequent ice formation of the water film. By continuously spraying the mist for a period of time, the subsequent formed ice film has sufficient thickness, and the preservation effect of the ice film on the food materials is improved.

[0096] Referring to Figure 9 It can be understood that the ice coating control method further comprises the following steps:

[0097] Step S700: When the opening time of the air duct opening reaches a second preset time, the first heating element and the second heating element are turned off, and a stop signal is sent.

[0098] Step S710: The ice coating mode is stopped, and the stop time is recorded.

[0099] When the time for the air outlet 140 to blow hot air reaches a second preset time, for example, 5 minutes or 6 minutes, the ice frost is melted to form a water film, and the water film can be attached to the food, and then, on the basis of the stop of the ultrasonic vibrator 221, the first fan 300 and the second fan 240, the controller further controls the first heating element 233 and the second heating element 141 to stop working, at this time, the air outlet 140 is switched to blow cold air, so that the water film on the food is frozen to form an ice film, that is, the ice coating is completed, the ice coating is formed completely, the ice coating effect is good, which is beneficial to the preservation of the food, and avoids the problems of serious water loss and nutrient loss of the food. At the same time, the controller sends a stop signal of the ice coating mode, and synchronously records the stop time, that is, the stop time point of the last stopped component in the ultrasonic vibrator 221, the first fan 300, the second fan 240, the first heating element 233 and the second heating element 141 is taken as a reference, and the stop time of the ice coating mode is started to be recorded.

[0100] With reference to Figure 9 It can be understood that the ice coating control method further comprises the following steps:

[0101] Step S800: Obtain a determination value of whether the food is stored in the freezing compartment, and determine whether the food is stored in the freezing compartment;

[0102] Step S900: Determine whether the stop time reaches a third preset time;

[0103] For example, a weighing instrument (not shown in the figure) is arranged at the bottom of the ice coating space 111 to detect the weight of the stored food, the weighing instrument is electrically connected with the controller, if the detected weight is greater than zero, it indicates that the ice coating space 111 stores food, and a signal is fed back to the controller; if the detected weight is always equal to zero, it indicates that the ice coating space 111 has no food, and a signal is fed back to the controller, and then the controller can obtain the determination value of whether the food is stored in the ice coating space 111.

[0104] It can be understood that the infrared detector can also be used to detect whether the food is stored in the ice coating space 111, the infrared detector is electrically connected with the controller, and similarly, the controller can obtain the determination value of whether the food is stored in the ice coating space 111.

[0105] When the determination value represents that the ice coating space 111 has food, and the stop time of the ice coating mode reaches the third preset time, the start instruction of the ice coating mode is sent again.

[0106] When the determination value represents that the ice coating space 111 has no food, the stop state of the ice coating mode is continuously maintained.

[0107] For example, the weighing instrument detects that the weight of the stored goods in the icing space 111 is greater than zero, or the infrared detector detects that the icing space 111 has goods, and at the same time, the stop time reaches the third preset time, for example, the stop time reaches 24 hours, so that the controller obtains the icing mode starting instruction again, and performs the next icing operation, that is, the food in the icing space 111 is iced again, which can be icing new food or re-icing food that has been iced, so as to improve the preservation effect. The icing can be automatically controlled without too much human intervention, and the control mode is simple and easy to implement.

Taking one processor and a memory as an example, the processor and the memory can be connected through a bus or other means.

The processor realizes the icing control method of the refrigerator in the second aspect of the present application by running the non-transitory software programs and instructions stored in the memory.
