[0060] With the improvement of people's quality of life, people's demand for refrigerators has extended from long-term food storage to other functions, such as fresh-keeping food or ice making functions.

[0061] At present, although some refrigerators have ice making function, because the water used for ice making contains a large amount of gas, when the water is frozen into ice blocks in the mold, because the temperature conduction direction is from outside to inside. In the case that the water outside is frozen to form ice blocks, the gas located in the inside of the ice blocks cannot be removed, so that a large amount of bubbles exist in the ice blocks, which results in low transparency of the ice blocks, and cannot meet the user's requirement for transparency of the ice blocks.

[0062] The utility model embodiment can include a water storage box 1, a first pipeline 2, a second pipeline 3, an ice making air blower 4 and an ice making mold 5, the first pipeline 2 is in liquid path communication with the water storage box 1, the second pipeline 3 is arranged on the outer surface of the first pipeline 2 and forms an ice making air duct 301 in cooperation with the first pipeline 2. The ice making air blower 4 is in gas path communication with the second pipeline 3. The ice making mold 5 is provided with an ice making cavity 501 and an ice making air cavity 502, wherein the ice making cavity 501 is in liquid path communication with the first pipeline 2, and the ice making air cavity 502 is in gas path communication with the second pipeline 3. When the ice making air blower 4 is working, cold air is sent into the ice making air cavity 502, the water in the ice making cavity 501 is slowly and uniformly cooled, so that the water in the ice making cavity 501 is slowly cooled, the temperature fluctuation is small and the supercooling state is reached. During the cooling process, the supercooling state is destroyed, the center of the ice making cavity 501 is simultaneously iced inside and outside, and the gas entering the ice block is greatly reduced. Therefore, the transparency of the ice block can be improved, and the user's requirement for the transparency of the ice block is met.

[0063] With reference to Figures 1-8 The utility model embodiment provides a kind of ice making device, the ice making device can include water storage box 1, first pipeline 2, second pipeline 3, ice making air blower 4 and ice making mold 5, the first pipeline 2 is in liquid path communication with the water storage box 1, the second pipeline 3 is arranged on the outer surface of the first pipeline 2 and forms an ice making air duct 301 in cooperation with the first pipeline 2. The ice making air blower 4 is in gas path communication with the second pipeline 3. The ice making mold 5 is provided with an ice making cavity 501 and an ice making air cavity 502, wherein the ice making cavity 501 is in liquid path communication with the first pipeline 2, and the ice making air cavity 502 is in gas path communication with the second pipeline 3. When the ice making air blower 4 is working, cold air is sent into the ice making air cavity 502, the water in the ice making cavity 501 is slowly and uniformly cooled, so that the water in the ice making cavity 501 is slowly cooled, the temperature fluctuation is small and the supercooling state is reached. During the cooling process, the supercooling state is destroyed, the center of the ice making cavity 501 is simultaneously iced inside and outside, and the gas entering the ice block is greatly reduced. Therefore, the transparency of the ice block can be improved, and the user's requirement for the transparency of the ice block is met.

[0064] The utility model discloses an ice making device, which comprises a water storage box 1, a first pipeline 2, a second pipeline 3, an ice making mold 5, an ice making fan 4 and a water pump 15.

[0065] The second pipeline 3 is arranged on the outer surface of the first pipeline 2 and cooperates with the first pipeline 2 to form an ice making air duct 301, that is, the refrigeration air in the ice making air duct 301 directly contacts the first pipeline 2, so that the water in the first pipeline 2 can be cooled. For example, the end of the ice making air duct 301 away from the ice making mold 5 can be provided with a refrigeration air inlet or a refrigeration air outlet. The ice making air cavity 502 is provided with a refrigeration air outlet or a refrigeration air inlet in communication with the outer surface of the ice making mold 5. The refrigeration air inlet is in communication with the air outlet of the ice making fan 4, so that the refrigeration air can be introduced into the ice making air duct 301 under the pressure of the ice making fan 4 and enter the ice making air cavity 502 of the ice making mold 5 along the ice making air duct 301. Or, the refrigeration air is introduced into the ice making air cavity 502 and then flows into the ice making air duct 301.

[0066] Therefore, the water in the water storage box 1 can be slowly and uniformly cooled by the ice making air duct 301 during flowing to the ice making mold 5, and the temperature distribution uniformity of the water in the ice making mold 5 during forming ice blocks can be ensured. The air flow of the refrigeration air outlet can also be in air path communication with the ice making fan 4, so as to form air flow circulation and realize the reuse of cold energy.

[0067] Under the working condition of the ice making fan 4, the water in the ice making cavity 501 is slowly and uniformly cooled according to the low-temperature cooling air introduced by the ice making fan 4, so that the water in the ice making cavity 501 has a slow cooling speed, a small temperature fluctuation and reaches a supercooling state. The supercooling state of water refers to a state that the temperature is lower than the freezing point but the water does not freeze or crystallize. The supercooling state of the water in the ice making cavity 501 is destroyed during the cooling process, so that the center of the ice making cavity 501 simultaneously freezes from the inside and the outside, and the gas entering the ice blocks is greatly reduced. Therefore, the transparency of the ice blocks can be improved to meet the user's requirement for the transparency of the ice blocks.

[0068] An optional utility model embodiment, refer to Figure 5 The ice making air cavity 502 surrounds the ice making cavity 501.

[0069] In the embodiment of the utility model, in order to improve the uniformity of the temperature distribution of water in the ice making cavity 501, the ice making air cavity 502 is arranged around the ice making cavity 501. For example, in some embodiments, the cross-sectional shape of the ice making cavity 501 can include but is not limited to spherical and rectangular, etc., and the cross-sectional shape of the ice making air cavity 502 is at least partially annular, so that it can partially surround or completely surround (also known as completely surround) the ice making cavity 501.

[0070] An optional embodiment of the utility model, referring to Figure 5 The ice making device further comprises a heating assembly 6 arranged inside the ice making mold 5, wherein the heating assembly 6 conducts heat to the ice making cavity 501 when working to melt the surface of the ice block in the ice making cavity 501.

[0071] In the embodiment of the utility model, the ice making device can further comprise a heating assembly 6 arranged inside the ice making mold 5. For example, the heating assembly 6 can be located in the mold wall between the ice making cavity 501 and the ice making air cavity 502, so that when the heating assembly 6 works, it can quickly conduct heat to the ice making cavity 501. Therefore, after the ice block in the ice making cavity 501 is manufactured, the heating assembly 6 is started to heat the ice block, so that the outer surface of the ice block (the surface close to the heating assembly 6) is melted, and the separation between the ice making mold 5 and the ice block is completed.

[0072] In some embodiments, the heating assembly 6 can include at least one heating sheet arranged around the outer surface of the ice making cavity 501, so as to improve the demolding efficiency of the ice block from the ice making mold 5.

[0073] An optional embodiment of the utility model, referring to Figure 4 and Figure 5 The ice making mold 5 can include a first mold 51, a rotating shaft 52, a second mold 53, and a first driving motor 54. The first mold 51 is fixedly connected with the first pipe 2 and the second pipe 3. The rotating shaft 52 is rotatably connected with the first mold 51. The second mold 53 is fixedly connected with the rotating shaft 52 and cooperates with the first mold 51 to form the ice making cavity 501 and the ice making air cavity 502. The first driving motor 54 is fixedly connected with the first mold 51, wherein the output shaft of the first driving motor 54 is coaxially fixed with the rotating shaft 52, and the first driving motor 54 drives the first mold 51 to rotate when working to open or close the ice making cavity 501.

[0074] The ice making mold 5 can further include a first mold 51, a rotating shaft 52, a second mold 53, and a first driving motor 54. The first mold 51 and the second mold 53 can be made of metal material, for example. The first mold 51 can be used as a lower mold, and the second mold 53 can be used as an upper mold, so that the ice making cavity 501 and the ice making air cavity 502 are formed by the cooperation of the first mold 51 and the second mold 53. For example, the structure of the first mold 51 can also be designed in layers, and the ice making cavity 501, the heating assembly 6, and the ice making air cavity 502 are arranged outward from the center of the ice making mold 5.

[0075] The first pipe 2 and the second pipe 3 are fixedly connected with the first mold 51, for example, the first pipe 2 can be welded and fixed with the first mold 51, and the second pipe 3 can be welded and fixed with the second mold 53. The rotating shaft 52 is rotatably connected to the first mold 51 and fixedly connected with the second mold 53. Thus, the rotating shaft 52 can drive the second mold 53 to rotate synchronously under the action of external force, and the included angle between the first mold 51 and the second mold 53 can be controlled by the rotation angle of the rotating shaft 52. Thus, the ice making cavity 501 can be opened or closed.

[0076] For example, the first driving motor 54 is fixed on the first mold 51, and the output shaft of the first driving motor 54 is coaxially fixed with the rotating shaft 52. The coaxial fixing can be understood as that the output shaft of the first driving motor 54 is fixedly connected with the rotating shaft 52, and the center axis of the output shaft of the first driving motor 54 coincides with the center axis of the rotating shaft 52. Thus, the rotating shaft 52 can be driven to rotate by the forward and reverse rotation of the first driving motor 54, and the second mold 53 fixed with the rotating shaft 52 can be driven to rotate forward or reverse. For example, in the case of forward rotation of the first driving motor 54, the second mold 53 makes a rotating motion close to the first mold 51 to cooperate with the first mold 51 to close the ice making cavity 501. For another example, in the case of reverse rotation of the first driving motor 54, the second mold 53 makes a rotating motion away from the first mold 51 to open the ice making cavity 501, so that the completely manufactured ice cubes can be poured out of the first mold 51.

[0077] An optional utility model embodiment is described with reference to Figure 3As shown, the ice making device can further include an ice making box 7 and a second driving motor 8, the ice making box 7 is provided with a containing cavity 701, the first pipe 2, the second pipe 3 and the ice making mold 5 are installed in the containing cavity 701, the first pipe 2 is coaxially fixed with the second pipe 3, and the second pipe 3 is rotationally connected to the ice making box 7. The second driving motor 8 is installed on the outer surface of the ice making box 7 and is coaxially fixed with the second pipe 3, and the second driving motor 8 drives the first mold 51 to rotate when working, so that the ice blocks in the first mold 51 fall into the containing cavity 701.

[0078] In the embodiment of the utility model, the ice making box 7 is provided with a containing cavity 701, and the containing cavity 701 is used for mounting ice making related devices, for example, the first pipe 2, the second pipe 3 and the ice making mold 5 are installed in the containing cavity 701. The first pipe 2 is coaxially fixed with the second pipe 3, which can be understood as the first pipe 2 is fixedly connected with the second pipe 3, and the central axis of the first pipe 2 coincides with the central axis of the second pipe 3. That is, the second pipe 3 is sleeved on the first pipe 2.

[0079] The second pipe 3 is rotationally connected with the ice making box 7. For example, the second pipe 3 has a certain height distance from the bottom of the ice making box 7. Therefore, the second pipe 3 can rotate around the ice making box 7 under the action of external force, and can drive the first mold 51 fixed with the second pipe 3 to rotate. Therefore, when the second mold 53 is away from the first mold 51 and the ice making cavity 501 is in an open state, the rotation of the first mold 51 can make the ice blocks in the first mold 51 fall downward and fall into the containing cavity 701.

[0080] The second driving motor 8 is installed on the outer surface of the ice making box 7, so that the second pipe 3 can be subjected to a rotating force. For example, the second driving motor 8 is fixed on the ice making box 7 and coaxially fixed with the second pipe 3. Among them, coaxial fixing can be understood as the output shaft of the second driving motor 8 is fixedly connected with the second pipe 3, and the central axis of the output shaft of the second driving motor 8 coincides with the central axis of the second pipe 3.

[0081] For example, when the ice cube manufacturing in the ice making cavity 501 is completed, the first driving motor 54 rotates forward to open the ice making cavity 501. The second driving motor 8 rotates forward to drive the first mold 51 to rotate, so that the ice cubes in the first mold 51 fall into the accommodating cavity 701. Then the second driving motor 8 reverses and drives the first mold 51 to rotate synchronously to return to the initial position, and the second driving motor 8 stops rotating. The first driving motor 54 reverses to drive the second mold 53 to rotate close to the first mold 51, so as to realize the closure of the ice making cavity 501. Thus, the next ice cube manufacturing step cycle can be performed.

[0082] An optional utility model embodiment, referring to Figure 3 and Figure 6 The ice making device further comprises an ice storage box 9 below the ice making box 7, the ice making box 7 can comprise an ice making bottom plate 71, a connecting rod 72 and an ice making side plate 73, and the ice making device further comprises a third driving motor 10. The connecting rod 72 is fixedly connected with the ice making bottom plate 71. The ice making side plate 73 and the ice making bottom plate 71 cooperate to form the accommodating cavity 701 and are rotationally connected with the connecting rod 72. The third driving motor 10 is fixed on the ice making side plate 73, wherein the output shaft of the third driving motor 10 is coaxially fixed with the connecting rod 72, and the third driving motor 10 drives the ice making bottom plate 71 to rotate when rotating, so that the ice cubes on the ice making bottom plate 71 fall into the ice storage box 9.

[0083] In the embodiment of the utility model, the ice storage box 9 is used for storing the ice cubes manufactured, so that the user can conveniently take the ice cubes from the ice storage box 9. In some optional embodiments, the ice making box 7 can comprise an ice making bottom plate 71, a connecting rod 72, an ice making side plate 73 and a third driving motor 10. The connecting rod 72 can be located on the central axis of the ice making bottom plate 71 and is fixedly connected with the ice making bottom plate 71. The number of the ice making side plates 73 can be multiple, for example, the number of the ice making side plates 73 can be four, so that the accommodating cavity 701 with an opening facing (towards) the ice making box 7 can be formed by cooperation of the four ice making side plates 73 and the ice making bottom plate 71. The connecting rod 72 is rotationally connected with the ice making side plate 73, for example, the two ends of the connecting rod 72 are respectively rotationally connected with two ice making side plates 73 opposite to each other.

[0084] The third driving motor 10 is fixed on the outer surface of the ice making side plate 73, and the output shaft of the third driving motor 10 is coaxially fixed with the connecting rod 72. Coaxial fixing can be understood as that the output shaft of the third driving motor 10 is fixedly connected with the connecting rod 72, and the central axis of the output shaft of the third driving motor 10 coincides with the central axis of the connecting rod 72. Therefore, under the condition that the third driving motor 10 rotates forward or reverses by a certain angle, the ice making bottom plate 71 can be driven to rotate, so that the accommodation cavity 701 and the ice storage box 9 form space communication, and the ice making bottom plate 71 is inclined during rotation, so that the ice blocks on the ice making bottom plate 71 can be guided into the ice storage box 9.

[0085] An optional utility model embodiment, referring to Figure 7 The ice making device can further include a carbon dioxide generating assembly 11 and a first valve 12.

[0102] An optional utility model embodiment, refer to Figure 9 、 Figure 10 And Figure 11 Show, the refrigerator can also include fresh-keeping drawer 17, air pipe 18, vacuum pump 19 and fresh-keeping fan 20. Fresh-keeping drawer 17 is slidably connected in refrigerator body 16, wherein, the fresh-keeping drawer 17 is provided with fresh-keeping cavity 1701 and fresh-keeping air cavity 1702 in gas path intercommunication with fresh-keeping cavity 1701, fresh-keeping air cavity 1702 with water storage box 1 gas path intercommunication. Air pipe 18 with fresh-keeping air cavity 1702 gas path intercommunication, vacuum pump 19 is located outside fresh-keeping air cavity 1702, and with air pipe 18 gas path intercommunication, vacuum pump 19 when working extracts carbon dioxide from water storage box 1 into fresh-keeping air cavity 1702. Fresh-keeping fan 20 is located in fresh-keeping air cavity 1702, fresh-keeping fan 20 when working, carbon dioxide located in fresh-keeping air cavity 1702 is sent into fresh-keeping drawer 17, to carry out food preservation.

[0103] The fresh-keeping drawer 17 is slidably connected in the refrigerator body 16, for example, the fresh-keeping drawer 17 can be provided with a fresh-keeping cavity 1701 and a fresh-keeping air cavity 1702. Wherein, the opening of the fresh-keeping cavity 1701 is upwardly arranged, so that the fresh-keeping cavity 1701 can be sealed by cooperating with the layered plate placed in the refrigerator body 16 and the fresh-keeping drawer 17. The fresh-keeping air cavity 1702 is a sealed cavity, which can be provided with a plurality of air inlets, for example, the fresh-keeping air cavity 1702 is in air communication with the water storage box 1, and the air pipe 18 is in air communication with the fresh-keeping air cavity 1702. The fresh-keeping fan 20 is installed in the fresh-keeping air cavity 1702, and the vacuum pump 19 is installed outside the fresh-keeping air cavity 1702. Therefore, when the vacuum pump 19 works, the residual carbon dioxide in the water storage box 1 can be introduced into the fresh-keeping air cavity 1702. There are at least two communication air inlets between the fresh-keeping air cavity 1702 and the fresh-keeping cavity 1701, so that the carbon dioxide in the fresh-keeping air cavity 1702 can be sent into the fresh-keeping cavity 1701 under the action of the fresh-keeping fan 20, and then the air flow in the fresh-keeping cavity 1701 is introduced into the fresh-keeping air cavity 1702 to form a fresh-keeping cycle.

[0104] In some embodiments, a third valve 21 is further arranged between the fresh-keeping drawer 17 and the water storage box 1, so that the air path between the water storage box 1 and the fresh-keeping drawer 17 can be controlled by the third valve 21. When the fresh-keeping drawer 17 does not work, the third valve 21 can be closed to disconnect the air path between the water storage box 1 and the fresh-keeping drawer 17.

[0105] Referring to Figure 12 The utility model discloses an embodiment further provides a control method of refrigerator, the refrigerator includes the refrigerator of any one of above utility model contents, the control method is applied to the controller of refrigerator, and the control method can include:

[0106] S1201, obtain the setting ice making mode, and the setting ice making mode includes the normal ice making mode and the bubble ice mode.

[0107] S1202, if the setting ice making mode is the normal ice making mode, starts the ice making fan, and sends air according to the first air supply temperature.

[0108] S1203, in the case that the temperature sensor located on the outer surface of the ice making mold detects that the temperature reaches the first temperature threshold, gradually reduces the air supply temperature of the ice making fan, so that the water in the ice making mold reaches the supercooling state.

[0109] S1204, in the case where the temperature reaches the set temperature threshold, reduce the air supply temperature of the ice-making blower, destroy the supercooling state to freeze.

[0110] In the embodiment of the utility model, the set ice-making mode refers to the ice-making mode determined by the user before ice-making based on the point selection operation on the mode control, which can be one of the conventional ice-making mode and the bubble ice mode. Among them, the ice block made according to the conventional ice-making mode has high transparency, and the ice block made according to the bubble ice mode has bubble taste. The controller and the electrical devices involved in the refrigerator are electrically connected respectively to control the working state of each electrical device through the controller, for example, the controller can be electrically connected with the ice-making blower 4 and the temperature sensor respectively.

[0111] In the case where the set ice-making mode selected by the user is the conventional ice-making mode, the ice-making blower is started. The first air supply temperature can be-30 to-18 DEG C (degree Celsius) range, so that the ice-making water can be rapidly cooled. The first temperature threshold can be understood as any value selected between-0.5 and 0.5 DEG C. In the case where the outer surface temperature of the ice-making mold 5 reaches the first temperature threshold, the air supply temperature of the ice-making blower 4 is gradually reduced, so that the water in the ice-making mold 5 reaches the supercooling state. Among them, the supercooling state of water refers to the temperature below the freezing point but still not solidified or crystallized. The temperature of the water in the ice-making mold 5 is gradually reduced by the air supply temperature of the ice-making blower 4, and the uniformity of the temperature distribution can be maintained.

[0112] The set temperature threshold can be-4.5 to-3.5 DEG C. When the temperature reaches the set temperature threshold, it is determined that the water in the ice-making mold 5 reaches the supercooling state and has a lower temperature. Therefore, the air supply temperature of the ice-making blower 4 is reduced, so that the supercooling state of the water in the ice-making mold 5 is destroyed under the stimulation of the low-temperature air supply temperature, and the water in the ice-making mold 5 can freeze rapidly. Therefore, there is no excess gas remaining in the obtained ice block, and the ice block has high transparency.

[0113] Referring to Figure 13 The utility model embodiment further provides another control method of refrigerator, the control method can include:

[0114] S1301, obtain the set ice-making mode, the set ice-making mode includes conventional ice-making mode and bubble ice mode.

[0115] S1302, if the set ice-making mode is conventional ice-making mode, start the ice-making blower and air supply according to the first air supply temperature.

[0116] S1303. When the temperature detected by the temperature sensor on the outer surface of the ice mold reaches the first temperature threshold, the ice-making fan is adjusted to deliver air at the second air delivery temperature.

[0117] S1304. When the temperature is detected to have reached the second temperature threshold, the ice-making fan is adjusted to deliver air at the set air delivery temperature.

[0118] S1305. When the temperature reaches the set temperature threshold, reduce the air supply temperature of the ice-making fan to break the subcooled state and allow icing to occur.

[0119] In this embodiment of the invention, the set ice-making mode refers to the ice-making mode determined by the user based on the selection operation of the mode control before ice making. It can be one of the regular ice-making mode and the bubble ice mode. When the user selects the regular ice-making mode, the ice-making fan is activated. The first air supply temperature can be within the range of -30 to -18°C, thereby rapidly cooling the ice-making water. The first temperature threshold can be understood as any value between -0.5 and 0.5°C. When the outer surface temperature of the ice mold 5 is detected to reach the first temperature threshold, the air supply temperature of the ice-making fan 4 is gradually reduced to make the water in the ice mold 5 reach a supercooled state. Here, the supercooled state of water refers to a temperature below the freezing point but not yet frozen or crystallized. By gradually reducing the air supply temperature of the ice-making fan 4, the temperature of the water in the ice mold 5 can be maintained, and the uniformity of its temperature distribution can be maintained.

[0120] For example, the cooling step of gradually reducing the air supply temperature of the ice-making fan 4 may include:

[0121] First, the air supply temperature of the ice-making fan 4 is reduced to a second air supply temperature, for example, the second air supply temperature T2 can be between -1.5 and -0.5℃. This allows for the slow cooling of water that has reached the first temperature threshold, stabilizing its temperature distribution and ensuring a stable water state in the ice-making mold 5, forming a supercooled state.

[0122] Second, the temperature detected by the temperature sensor is acquired, and it is determined whether the current temperature reaches (is equal to or lower than) a second temperature threshold. The second temperature threshold can be any value between -1.5 and -0.5℃, for example, -0.5℃, -1℃, or -1.5℃. If the current temperature is determined to have reached the second temperature threshold, the ice-making fan 4 can be adjusted to deliver air at a set air delivery temperature, for example, the set air delivery temperature can be between -4.5 and -3.5℃.

[0123] The set temperature threshold value can be a value selected between -4.5 and -3.5℃. When the temperature reaches the set temperature threshold value, it is determined that the water in the ice-making mold 5 reaches a super-cooled state and has a lower temperature. Thus, the air supply temperature of the ice-making air blower 4 is reduced, so that the super-cooled state of the water in the ice-making mold 5 can be destroyed under the stimulation of the air supply at a lower temperature, and the water in the ice-making mold 5 can be quickly frozen. Thus, the obtained ice cubes have no residual gas and have high transparency.

[0124] In some optional embodiments, the air supply temperature of the ice-making air blower 4 can be further divided into finer intervals, and the water in the ice-making mold 5 can be slowly cooled. For example, when the temperature reaches a second temperature threshold value, the ice-making air blower 4 is first adjusted to supply air at a third air supply temperature, for example, the third air supply temperature T3 can be -2.5 to -1.5℃. When the temperature reaches a third temperature threshold value, which is a value selected between -2.5 and -1.5℃, the ice-making air blower 4 is adjusted to supply air at a fourth air supply temperature. For example, the fourth air supply temperature T4 can be -3.5 to -2.5℃. When the temperature reaches a fourth temperature threshold value, which is a value selected between -3.5 and -2.5℃, the ice-making air blower 4 is adjusted to supply air at a fifth air supply temperature (or a set air supply temperature). For example, the fifth air supply temperature T4 can be between -4.5 and -3.5℃. The set temperature threshold value can be a value selected between -4.5 and -3.5℃. When the temperature reaches the set temperature threshold value, it is determined that the water in the ice-making mold 5 reaches a super-cooled state and has a lower temperature. Thus, the air supply temperature of the ice-making air blower 4 is reduced, for example, to the first air supply temperature for cooling, so that the super-cooled state of the water in the ice-making mold 5 can be destroyed under the stimulation of the cooling air at a higher temperature, and the water in the ice-making mold 5 can be quickly frozen. Thus, the obtained ice cubes have no residual gas and have high transparency.

[0125] In some optional embodiments, the control method further comprises:

[0126] After the ice-making air blower 4 is kept running at the first air supply temperature for a first time length, the heating assembly 6 is started to heat for a second time length. The first time length can be about 30 minutes, and the second time length can be 10 seconds, 12 seconds, etc. Those skilled in the art can determine the specific time length according to actual test results, and the first time length and the second time length are not limited herein.

[0127] The first driving motor 54 is controlled to open the ice making cavity 501, and the second driving motor 8 is controlled to rotate the ice making mold 5, so that the ice cubes fall into the containing cavity 701.

[0128] The third driving motor 10 is further controlled to drive the ice making bottom plate 71 to rotate, so that the ice cubes in the containing cavity 701 fall into the ice storage box 9, waiting for the user to take them.

[0129] When the refrigerator includes both the conventional ice making mode and the bubble ice making mode, the user can set the ice making mode through the operation of the mode control, and the third driving motor 10 is controlled to rotate in the forward direction or in the reverse direction according to the set ice making mode, so that the conventional ice cubes and the bubble ice cubes can be stored separately in the ice storage box 9 through the first ice storage cavity 901 and the second ice storage cavity 902.

[0130] In some optional embodiments, the sidewall or the bottom wall of the ice storage box 9 can be further provided with a pressure sensor, and when the pressure sensor detects that the number of ice cubes in the ice storage box 9 is relatively large, the ice making mode is stopped. For example, the first valve 12 and the second valve 14 can be closed, and the water pump 15 and the ice making fan 4 can be stopped.

[0131] When the user selects the bubble ice making mode as the set ice making mode, the controller starts the carbon dioxide generating assembly 11 to work, and opens the first valve 12, so that the carbon dioxide can enter the water storage box 1 to form bubble water. Meanwhile, the third valve 21 is opened, and the vacuum pump 19 is controlled to work and the fresh-keeping fan 20 is controlled to work, so that the water overflowed from the water storage box is extracted into the fresh-keeping air cavity 1702, and the carbon dioxide gas in the fresh-keeping air cavity 1702 is sent into the fresh-keeping drawer 17 through the fresh-keeping fan 20.

[0132] In some examples, the vacuum pump 19 can be controlled to work first, and the fresh-keeping air cavity 1702 can be further provided with a carbon dioxide sensor. When the carbon dioxide concentration reaches a preset concentration threshold, the vacuum pump 19 and the third valve 21 are closed, and the communication opening between the fresh-keeping air cavity 1702 and the fresh-keeping cavity 1701 (which can also be controlled by a valve) and the fresh-keeping fan 20 are opened, so that the air in the fresh-keeping cavity 1701 can be circulated under the pressure of the fresh-keeping fan 20. The carbon dioxide concentration in the fresh-keeping drawer 17 can be increased to improve the fresh-keeping effect of the food materials in the fresh-keeping drawer 17.

[0133] Start the ice-making fan, and air supply is carried out according to the first air supply temperature, so that the bubble water flowing from the water storage box 1 to the ice-making mold 5 is rapidly cooled to form bubble ice. The middle position of the bubble ice can include bubble water that has not frozen.

[0134] After the ice-making fan 4 operates for a third duration, the second driving motor 8 can also be started to rotate, so that the bubble water that has not frozen is located at the center of the bubble ice, the distribution uniformity of the structure of the bubble ice is improved, and the user experience can be improved.

[0135] After a bubble ice is manufactured, the third driving motor 10 can be controlled to reverse according to the set ice-making mode, so that the last obtained regular ice block and bubble ice block can be separately stored in the ice storage box 9 through the first ice storage cavity 901 and the second ice storage cavity 902.

[0136] Alternatively, after the set ice-making mode is obtained, the method step of controlling the third driving motor 10 to reverse according to the set ice-making mode is performed, and the execution sequence thereof is not limited.

[0137] In summary, the control method of the refrigerator can include the following steps: first, obtaining a set ice-making mode; if the set ice-making mode is a regular ice-making mode, starting the ice-making fan 4 and air supply is carried out according to the first air supply temperature. Then, when the temperature sensor located on the outer surface of the ice-making mold 5 detects that the temperature reaches a first temperature threshold, gradually reducing the air supply temperature of the ice-making fan 4, so that the water in the ice-making mold 5 reaches a supercooling state. And when the temperature reaches a set temperature threshold, the air supply temperature of the ice-making fan 4 is reduced to freeze the supercooling state. So that the center of the ice-making cavity 501 freezes at the same time inside and outside, and the gas entering the ice block is greatly reduced. So you can improve the transparency of the ice block to meet the user's requirements for ice block transparency.
