Description

Technical Field

[0001] The embodiments of the present application relate to refrigeration technology, and more particularly to a refrigerator. Background Art

[0002] A refrigerator is a refrigeration device that maintains a constant low temperature. It is also a civilian product that keeps food or other items at a constant low temperature.

[0003] In the related art, a refrigerator includes a refrigerator body, a water box located inside the refrigerator body, an ice maker, and a water pump. The ice maker and the water pump are connected through a first pipe, and the water box and the water pump are connected through a second pipe. The water pump is used to transport water in the water box to the ice maker.

[0004] However, the ice maker cannot recognize whether water is injected or not. Utility Model Content

[0005] An embodiment of the present application provides a refrigerator that can identify water injection into an ice maker with high accuracy.

[0006] In a first aspect, an embodiment of the present application provides a refrigerator, comprising:

[0007] A box body, the box body is configured with a first chamber and a second chamber;

[0008] a water box, the water box being located in the second chamber;

[0009] an ice maker, the ice maker being located in the first chamber;

[0010] A water pump is connected to the water box and is located above the ice maker;

[0011] The first pipeline is connected to the water pump and the ice maker, and the first pipeline includes:

[0012] a first connecting section, the first connecting section being connected to a water pump;

[0013] a second connecting section, the second connecting section being located below the first connecting section, the second connecting section being connected to an end of the first connecting section facing away from the ice maker, and the second connecting section being connected to the ice maker;

[0014] wherein a first angle between the extension direction of the first connecting section and the horizontal plane is greater than a second angle between the extension direction of the second connecting section and the horizontal plane;

[0015] a heating element, the heating element being arranged on the second connecting section;

[0016] The first temperature sensor is arranged on the bottom wall of the second connecting section and is close to the first connecting section.

[0017] Based on the principle that when the temperature of the liquid in the water box is lower than that of the first pipe, the liquid flows through the first pipe, causing the temperature of the first pipe to decrease. This application provides a first pipe, a heater, and a first temperature sensor. The first pipe connects the water pump and the ice maker. The heater heats the first pipe, and the first temperature sensor detects the temperature of the first pipe. Thus, when water flows through the first pipe, the temperature of the first pipe decreases. The first temperature sensor detects the decrease, indicating that water has been injected into the ice maker. Furthermore, to improve identification accuracy, based on the principle that when the amount of liquid is small, the liquid flows along the bottom wall of the first pipe under the action of gravity. In this application, the first pipe includes a first connecting section and a second connecting section located at the bottom of the first connecting section. Under the action of the water pump, the liquid in the water box passes through the first and second connecting sections and is then transported to the ice maker. The first angle between the first connecting section and the horizontal plane is greater than the second angle between the second connecting section and the horizontal plane. The heater is provided on the second connecting section. The first temperature sensor is provided on the bottom wall of the second connecting section, adjacent to the first connecting section. In this way, when the amount of water is small, the water will flow along the bottom of the second connecting section when it flows to the second connecting section. The first temperature sensor can still identify the temperature change of the second connecting section, thereby identifying that water has been injected into the ice maker.

[0018] In some embodiments, 85 degrees is less than the first angle.

[0019] When the first angle is less than 85 degrees, the first connecting section occupies a larger space.

[0020] In some embodiments, 5 degrees is less than the second angle, and the second angle is less than 15 degrees.

[0021] When the second angle is less than 5 degrees, the second connecting section is relatively flat, and liquid is likely to remain in the second connecting section, thereby being frozen and blocked.

[0022] When the second angle is greater than 15 degrees, the liquid in the second connecting section flows to the ice maker at a high speed and is prone to splashing.

[0023] In some embodiments, the heating element is close to the first temperature sensor, and the heating element and the first temperature sensor are arranged side by side along the extension direction of the second connecting section.

[0024] When the heating element is close to the first temperature sensor, the temperature of the outer wall at the location of the first temperature sensor is higher, and the temperature difference between the outer wall and the liquid can be larger. When the liquid flows, the temperature change is more obvious, and the first temperature sensor can easily detect the temperature change. Therefore, the accuracy of water filling identification in the ice maker is higher.

[0025] In some embodiments, a heat-insulating component is further included, which is sleeved on the outer wall of the second connecting section, and the heating component and the first temperature sensor are located inside the heat-insulating component.

[0026] The heat-insulating member is used to keep the second connecting section warm, thereby reducing heat loss and helping to reduce the impact on the refrigeration effect of the refrigeration chamber.

[0027] In some embodiments, the ice making machine comprises;

[0028] Bracket;

[0029] An ice making box, wherein the bracket is connected to the inner wall of the box body, the bracket is configured with a receiving cavity, the ice making box is located in the receiving cavity, and is connected to the bracket;

[0030] The refrigerator also includes:

[0031] The air duct assembly is located in the box and has an air outlet structure;

[0032] The air guide piece is constructed with an air guide cavity, the air guide piece is sleeved on the peripheral side of the air outlet structure, the inner cavity of the air outlet structure is connected to the air guide cavity, the air guide piece is connected to the bracket, and the air guide cavity is connected to the accommodating cavity.

[0033] In this way, the air guide member can guide the cold air blown out by the air duct assembly into the ice making box of the ice maker.

[0034] In some embodiments, there is a distance e between the outer wall of the air outlet structure and the inner wall of the air guide.

[0035] The cold air in the air outlet structure can flow to the outside through the above-mentioned spacing, thereby blowing away the moist air between the air outlet structure and the air guide, thereby effectively avoiding condensation and ice formation between the air outlet structure and the air guide.

[0036] In some embodiments, 1 mm < spacing e.

[0037] When the spacing is less than 1mm, the spacing is small, the cold air flowing through the spacing is less, and it is not easy to blow away the humid air. The position between the air outlet structure and the air guide is prone to condensation and ice.

[0038] In some embodiments, along the depth direction of the box body, from the end away from the air guide to the end close to the air guide, the height of the top wall of the air outlet structure decreases, and the height of the bottom wall of the air outlet structure increases;

[0039] Along the depth direction of the box body, the height of the inner bottom wall of the air guide increases from an end close to the air outlet structure to an end far away from the air outlet structure.

[0040] In this way, condensation on the top wall of the air outlet structure can slide along the top of the air outlet structure into the air guide cavity and then be blown away by the cold air in the air guide cavity. Condensation on the bottom wall of the air outlet structure can slide along the bottom of the air outlet structure to the bottom of the air outlet structure, and condensation on the inner bottom wall of the air guide can slide along the inner bottom wall of the air guide to the outside of the air guide, thereby effectively preventing accumulation between the outer wall of the air outlet structure and the inner wall of the air guide, and thus effectively preventing ice from forming.

[0041] In some embodiments, a second temperature sensor is further included. The second temperature sensor is connected to the bracket and is located on a side of the ice making box that is away from the door of the refrigerator.

[0042] In this way, when the user opens the door, the second temperature sensor is not easily affected by the air outside the refrigerator. BRIEF DESCRIPTION OF THE DRAWINGS

[0072] As described in the background art, the ice maker cannot identify whether water is injected.

[0073] To solve the above technical problems, based on the principle that when the temperature of the water in the water box is lower than the temperature of the sidewall of the first pipe, the temperature of the sidewall of the first pipe decreases as the water flows through the first pipe. This application provides a first pipe, a heater, and a first temperature sensor. The first pipe connects the water pump and the ice maker, the heater heats the sidewall of the first pipe, and the first temperature sensor detects the temperature of the sidewall of the first pipe. Thus, when water flows through the first pipe, the temperature of the sidewall of the first pipe decreases. The first temperature sensor detects the temperature decrease, indicating that water has been injected into the ice maker.

[0074] Furthermore, in order to improve the accuracy of recognition. Based on the principle that when the amount of water is small, the water will flow along the bottom wall of the first pipe under the action of gravity. In this application, the first pipe includes a first connecting section and a second connecting section located at the bottom of the first connecting section. Under the action of the water pump, the water in the water box passes through the first connecting section and the second connecting section and is located in the ice maker. The first angle between the extension direction of the first connecting section and the horizontal plane is greater than the second angle between the extension direction of the second connecting section and the horizontal plane. Wherein, the heating element is arranged on the outer wall of the second connecting section. The first temperature sensor is arranged on the outer bottom wall of the second connecting section and is close to the first connecting section. In this way, when the amount of water is small, the water will flow along the bottom of the second connecting section when it flows to the second connecting section. The first temperature sensor can still recognize the temperature change of the second connecting section, thereby recognizing that water has been injected into the ice maker.

Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0082] The embodiment of the present application provides a refrigerator, wherein the refrigerator can be a direct cooling refrigerator or an air cooling refrigerator.

[0083] Figure 1 This is a schematic diagram of the external structure of the refrigerator provided in an embodiment of the present application. Figure 2 Schematic diagram of the internal structure of the refrigerator provided in an embodiment of the present application.

[0084] See also Figure 1 and Figure 2 As shown, in some embodiments, the refrigerator includes a cabinet 100 .

[0085] The housing 100 may define a refrigeration chamber. There may be at least one refrigeration chamber. When there is one refrigeration chamber, the refrigeration chamber may be any one of a refrigerator, a freezer, or a temperature-varying chamber. When there are two or more refrigeration chambers, the plurality of refrigeration chambers may include at least one or more of the refrigerator, the freezer, or the temperature-varying chamber.

[0086] In some embodiments, the housing 100 is configured with a first chamber.

[0087] In some embodiments, the housing 100 is configured with a second chamber.

[0088] In some embodiments, the first chamber and the second chamber may be arranged side by side along the height direction of the housing 100. Alternatively, the first chamber and the second chamber may be arranged side by side along the width direction of the housing 100. The height direction is the direction indicated by the Z axis in the figure, and the width direction is the direction indicated by the X axis in the figure.

[0089] Specifically, the first chamber may be a freezing chamber, and the second chamber may be a refrigerating chamber.

[0090] In some embodiments, the refrigerator includes a door body 200 .

[0091] The door 200 is an openable cover provided on the front side of the box body 100 to close and open the refrigeration chamber and to take items into and out of the storage chamber. It should be noted that the number of the door 200 can be one, two or more.

[0092] In some embodiments, the refrigerator includes a refrigeration system.

[0093] The refrigeration system may include a compressor 300, a condenser, a throttling device and an evaporator 400. The compressor 300, the condenser, the throttling device and the evaporator 400 are connected in series in sequence through pipelines, and refrigerant flows in the pipelines.

[0094] In some embodiments, the refrigerator is an air-cooled refrigerator.

[0095] In some embodiments, an air duct assembly 500 is provided in the box body 100, and the air duct assembly 500 divides the inner cavity into a cold source chamber and a refrigeration chamber.

[0096] In some embodiments, the cold source chamber is located at the back of the refrigeration chamber.

[0097] In some embodiments, the evaporator 400 and the fan are disposed in the cold source chamber.

[0098] When the compressor 300 is working, low-temperature, low-pressure refrigerant is sucked into the compressor 300, compressed into high-temperature, high-pressure superheated gas in the cylinder of the compressor 300, and then discharged into the condenser.

[0099] The high-temperature, high-pressure refrigerant gas dissipates heat through the condenser, and the temperature continues to drop. It is gradually cooled into a saturated vapor at room temperature and high pressure, and further cooled into a saturated liquid. The pressure of the refrigerant remains almost unchanged during the entire condensation process.

[0100] The throttling device may include a pressure reducing tube or an electronic expansion valve. In this application, the throttling device is described as including a pressure reducing tube as an example. The pressure reducing tube has low cost and is not prone to abnormal failures.

[0101] After condensation, the saturated refrigerant liquid passes through a pressure reducing pipe, where it undergoes throttling and pressure reduction, transforming into a wet vapor at room temperature and low pressure. This wet vapor then passes through the evaporator 400, absorbing heat and vaporizing. This not only lowers the temperature of the evaporator 400 and its surroundings but also transforms the refrigerant into a low-temperature, low-pressure gas.

[0102] The evaporator 400 cools the air in the cold source chamber to reduce the temperature of the air in the cold source chamber. Under the action of the fan, the cold air in the cold source chamber flows into the freezer through the air duct assembly 500, so that the temperature of the freezer is reduced, so that the ice maker can make ice.

[0103] The refrigerant coming out of the evaporator 400 returns to the compressor 300 again, and the above process is repeated, so that the evaporator 400 can continue to cool the air in the cold source chamber, thereby maintaining the freezing chamber at a set temperature.

[0104] In some embodiments, the refrigerator includes a water box 600. The water box 600 is used to hold liquid, thereby facilitating the addition of liquid to the ice maker.

[0105] The water box 600 is located in the second chamber.

[0106] In some embodiments, the refrigerator includes an ice maker 700. The ice maker 700 is used to make ice cubes.

[0107] The ice maker 700 is located in the first chamber.

[0108] In some embodiments, the refrigerator includes a water pump 800 . The water pump 800 is used to deliver water in the water box 600 to the ice maker 700 .

[0109] In some embodiments, the water pump 800 is in communication with the water box 600. The water pump 800 is in communication with the ice maker 700.

[0110] Specifically, the water pump 800 may be in communication with the water box 600 through a second pipe.

[0111] In some embodiments, the water pump 800 is located above the ice maker 700 .

[0112] In some embodiments, the refrigerator includes a first pipe 900. The first pipe 900 connects the water pump 800 and the ice maker 700.

[0113] Under the action of the water pump 800 , the liquid in the water box 600 enters the ice maker 700 through the second pipe, the water pump 800 and the first pipe 900 .

[0114] Figure 3 This is a structural diagram of the first pipe, the first temperature sensor, and the heat preservation component in the refrigerator provided in an embodiment of the present application. Figure 4 for Figure 3 sectional view of .

[0115] See also Figure 3 and Figure 4 As shown, in some embodiments, the first pipe 900 includes a first connecting section 910 .

[0116] In some embodiments, the extending direction of the first connecting section 910 forms a first angle a with the horizontal plane. The first connecting section 910 is connected to the water pump 800 .

[0117] Specifically, the first angle a is the angle between the axis of the first connecting section 910 and the horizontal plane. The first angle a is set to a value not greater than 90 degrees.

[0118] It is understandable that, since the water pump 800 is located above the ice maker 700 , in order to utilize gravity to promote the flow of liquid, the extension direction of the first connecting section 910 forms a first angle a with the horizontal plane.

[0119] In some embodiments, the first pipe 900 includes a second connecting section 920 .

[0120] In some embodiments, the second connecting section 920 is located below the first connecting section 910. An end of the first connecting section 910 facing away from the ice maker 700 is connected to the second connecting section 920, and the second connecting section 920 is connected to the ice maker 700.

[0121] In some embodiments, the extension direction of the second connecting segment 920 forms a second angle b with the horizontal plane.

[0122] Specifically, the second angle b is the angle between the axis of the second connecting section 920 and the horizontal plane. The second angle b is set to a value not greater than 90 degrees.

[0123] It can be understood that, in order to utilize gravity to promote the flow of liquid, the extension direction of the second connecting section 920 has a second angle b with the horizontal plane.

[0124] In some embodiments, the first angle a is greater than the second angle b.

[0125] It is understood that because the second connecting section 920 is connected to the ice maker 700, when the second angle b is greater than or equal to the first angle a, the liquid in the second connecting section 920 is likely to splash when it flows into the ice maker 700. Alternatively, the space occupied along the depth direction of the box 100 is relatively large. The depth direction is the direction indicated by the Y axis in the figure.

[0126] It is understood that by providing the first connecting section 910 and the second connecting section 920, and by having the first connecting section 910 and the second connecting section 920 have different inclination angles, with the first angle a being greater than the second angle b, gravity is advantageously utilized to promote the flow of liquid, and the overall length and occupied space of the first pipe 900 are advantageously reduced. Furthermore, splashing of liquid is advantageously reduced.

[0127] In some embodiments, the refrigerator includes a heating element 1200 .

[0128] In some embodiments, the heating element 1200 is disposed on the first pipe 900 , and the heating element 1200 is used to heat the first pipe 900 .

[0129] In some embodiments, the first pipe 900 may be a metal pipe, such as an aluminum pipe, so as to facilitate faster heat transfer.

[0130] In some embodiments, the heating element 1200 may be a heating wire or a heating plate.

[0131] In some embodiments, the refrigerator includes a first temperature sensor 1000 .

[0132] In some embodiments, the first temperature sensor 1000 is disposed on the first pipe 900 , and the first temperature sensor 1000 is used to detect the temperature of the first pipe 900 .

[0133] It is understood that, based on the principle that when the temperature of the liquid in the water box 600 is lower than that of the first pipe 900, the liquid flows through the first pipe 900, causing the temperature of the first pipe 900 to decrease. The present application provides a first pipe 900, a heater 1200, and a first temperature sensor 1000. The first pipe 900 connects the water pump 800 and the ice maker 700, the heater 1200 heats the first pipe 900, and the first temperature sensor 1000 detects the temperature of the first pipe 900. Thus, when liquid flows through the first pipe 900, the temperature of the first pipe 900 decreases. The first temperature sensor 1000 detects the temperature drop, indicating that liquid has been injected into the ice maker 700.

[0134] In some embodiments, the heating element 1200 is disposed on the second connecting section 920 . The heating element 1200 is used to heat the second connecting section 920 .

[0135] Specifically, the heating element 1200 is disposed on the outer wall of the second connecting section 920 .

[0136] In some embodiments, the first temperature sensor 1000 is disposed on the bottom wall of the second connecting section 920. The first temperature sensor 1000 is used to detect the temperature of the second connecting section 920.

[0137] Specifically, in some embodiments, the first temperature sensor 1000 is disposed on the outer bottom wall of the second connecting section 920 .

[0138] Furthermore, to improve recognition accuracy, based on the principle that when the amount of liquid is low, the liquid flows along the bottom wall of the first pipe 900 under the action of gravity. In this application, the first pipe 900 includes a first connecting section 910 and a second connecting section 920 located at the bottom of the first connecting section 910. Under the action of the water pump 800, the liquid in the water box 600 passes through the first connecting section 910 and the second connecting section 920 and is then placed inside the ice maker 700. The first angle a between the extension direction of the first connecting section 910 and the horizontal plane is greater than the second angle b between the extension direction of the second connecting section 920 and the horizontal plane. The heater 1200 is disposed on the second connecting section 920. The first temperature sensor 1000 is disposed on the bottom wall of the second connecting section 920. Thus, when the amount of water is low, the water flowing into the second connecting section 920 will flow along the bottom of the second connecting section 920. However, the first temperature sensor 1000 can still detect the temperature change in the second connecting section 920, thereby identifying the injection of liquid into the ice maker 700.

[0139] In some embodiments, the first temperature sensor 1000 is disposed on the outer bottom wall of the second connecting section 920 and is close to the first connecting section 910 .

[0140] It is understood that when the liquid first flows from the first connecting section 910 to the second connecting section 920, it does not undergo heat transfer through the second connecting section 920 and is therefore at a lower temperature, resulting in a more significant cooling effect on the second connecting section 920. This allows the first temperature sensor 1000 to easily detect temperature changes, thus providing a higher degree of accuracy in identifying water filling in the ice maker 700.

[0141] In some embodiments, the first angle a is 85-90 degrees.

[0142] In some embodiments, the first angle a is greater than 85 degrees.

[0143] In some embodiments, the first angle a is less than 90 degrees.

[0144] In some embodiments, the first angle a may be 86 degrees or 88 degrees.

[0145] It is understandable that when the first angle a is less than 85 degrees, the first connecting section 910 occupies a larger space. For example, along the depth direction of the box body 100, the first connecting section 910 occupies a larger space.

[0146] In some embodiments, the second angle b is 5-15 degrees.

[0147] In some embodiments, the second angle b is 9-11 degrees.

[0148] In some embodiments, the second angle b may be 10 degrees.

[0149] It is understandable that when the second angle b is less than 5 degrees, the second connecting section 920 is relatively flat, and liquid is likely to remain in the second connecting section 920, thereby being frozen and blocked.

[0150] When the second angle b is greater than 15 degrees, the liquid in the second connecting section 920 flows to the ice maker 700 at a high speed and is prone to splashing.

[0151] In some embodiments, the first pipe 900 further includes a curved portion 930 .

[0152] The arcuate portion 930 is located between the first connecting section 910 and the second connecting section 920, and the first connecting section 910 is connected to the second connecting section 920 via the arcuate portion 930. In this way, liquid is unlikely to remain at the connection between the first connecting section 910 and the second connecting section 920 in the first pipe 900.

[0153] In some embodiments, the heating element 1200 is close to the first temperature sensor 1000 .

[0154] In some embodiments, the heating element 1200 and the first temperature sensor 1000 are arranged side by side along the extension direction of the second connecting section 920 .

[0155] As can be understood, since heating element 1200 is located close to first temperature sensor 1000, the temperature of the outer wall at the location of first temperature sensor 1000 is higher, and the temperature difference with the liquid can be larger, resulting in a more significant temperature change when liquid is flowing. This makes it easier for first temperature sensor 1000 to detect temperature changes, thus increasing the accuracy of identifying water filling in ice maker 700.

[0156] In some embodiments, the refrigerator further includes a heat-insulating member 1100. The heat-insulating member 1100 is used to keep the second connecting section 920 warm, thereby reducing heat loss and helping to reduce the impact on the refrigeration effect of the refrigeration chamber.

[0157] The heat-insulating component 1100 is sleeved on the outer wall of the second connecting section 920 .

[0158] In some embodiments, the heating element 1200 and the first temperature sensor 1000 are located inside the heat preservation element 1100 .

[0159] In some embodiments, the thermal insulation component 1100 may be thermal insulation cotton or thermal insulation foam.

[0160] Figure 5 This is a schematic structural diagram of the air duct assembly, ice maker and air guide member in the refrigerator provided in an embodiment of the present application.

[0161] See also Figure 5 As shown, in some embodiments, ice maker 700 includes a stand 710 .

[0162] The bracket 710 is connected to the inner wall of the box body 100 , and the bracket 710 is configured with a receiving cavity.

[0163] In some embodiments, the ice maker 700 includes an ice making box (not shown).

[0164] The ice making box is located in the accommodating cavity and is connected to the bracket 710 .

[0165] In some embodiments, the refrigerator further includes a second temperature sensor 1300 .

[0166] In some embodiments, the second temperature sensor 1300 is connected to the outer wall of the bracket 710 .

[0167] In some embodiments, the second temperature sensor 1300 is located in the accommodating cavity, and the second temperature sensor 1300 is connected to the inner wall of the bracket 710 .

[0168] It should be noted that the second temperature sensor 1300 does not use an infrared sensor to measure the temperature of the ice box, nor does it use an ordinary sensor to contact the ice box to measure the temperature (because the ice box cannot be detachable). Instead, the second temperature sensor 1300 is used to measure the air temperature around the ice maker 700.

[0169] In some embodiments, the second temperature sensor 1300 is located on a side of the ice making box away from the door body 200. In this way, when the user opens the door, the second temperature sensor 1300 is not easily affected by the air outside the refrigerator.

[0170] In some embodiments, the second temperature sensor 1300 is located on a side of the bracket 710 away from the air outlet structure 510 of the air duct assembly 500. In this way, the second temperature sensor 1300 is not easily affected by the air outlet of the air duct assembly 500.

[0171] Figure 6 This is a schematic structural diagram of the air duct assembly in the refrigerator provided in an embodiment of the present application.

[0172] See also Figure 6As shown, in some embodiments, the air duct assembly 500 is configured with an air outlet structure 510 .

[0173] It should be noted that the air duct assembly 500 has been omitted from the accompanying drawings.

[0174] Figure 7 This is a schematic diagram of the structure of the air guide member in the refrigerator provided in the embodiment of the present application. Figure 8 This is a schematic structural diagram of the air guide member in the refrigerator provided in an embodiment of the present application from another angle.

[0175] See also Figure 7 and Figure 8 As shown, in some embodiments, the refrigerator further includes an air guide 1400. The air guide 1400 is used to guide the cold air blown out by the air duct assembly 500 into the ice making box of the ice maker 700.

[0176] In some embodiments, the air guide member 1400 is configured with an air guide cavity 1410 .

[0177] Figure 9 for Figure 5 The main view, Figure 10 for Figure 9 The cross-sectional view along the AA direction, Figure 11 for Figure 10 A partial enlarged view of point B in the middle.

[0178] See also Figure 5 、 Figures 9 to 11 As shown, the air guide 1400 is connected to the bracket 710. The air guide cavity 1410 is communicated with the accommodating cavity.

[0179] The air guide member 1400 is sleeved on the circumference of the air outlet structure 510 , and the air outlet structure 510 is communicated with the air guide cavity 1410 .

[0180] The cold air in the air duct assembly 500 enters the accommodating cavity through the air outlet structure 510 and the air guide cavity 1410 of the air guide member 1400 , and is connected to the ice making box of the ice maker 700 .

[0181] In some embodiments, the air guide 1400 is detachably connected to the bracket 710, for example, by snap-fitting or screw connection.

[0182] It will be appreciated that the air guide 1400 is detachably connected to the bracket 710. This allows the air guide 1400 to be replaced when different refrigerators have different depth dimensions, thereby meeting the needs of different refrigerators. For example, as the depth dimension of a refrigerator increases, a larger air guide 1400 can be replaced. As the depth dimension of a refrigerator decreases, a smaller air guide 1400 can be replaced. This eliminates the need to modify the ice maker 700 and air duct assembly 500, thereby improving versatility.

[0183] It should be noted that the depth direction is the direction indicated by the Y axis.

[0184] See also Figure 11 As shown, in some embodiments, there is a distance e between the outer wall of the air outlet structure 510 and the inner wall of the air guide 1400 .

[0185] It can be understood that the cold air in the air outlet structure 510 can flow to the outside through the spacing e, thereby blowing away the humid air between the air outlet structure 510 and the air guide 1400, thereby effectively avoiding condensation and ice formation between the air outlet structure 510 and the air guide 1400.

[0186] In some embodiments, 1 mm < spacing e.

[0187] It is understandable that when the spacing e is less than 1 mm, the spacing e is small, the cold air flowing through the spacing e is less, and it is not easy to blow away the humid air, and the position between the air outlet structure 510 and the air guide 1400 is prone to condensation and ice.

[0188] In some embodiments, the spacing e is no greater than 5 mm.

[0189] It can be understood that when the distance e is greater than 5 mm, the leakage of cold air is greater.

[0190] In some embodiments, the spacing e is 2 mm.

[0191] Specifically, simulations show that when the air outlet structure 510 outputs 9.32 m³ / h, the air outlet of the air guide 1400 is 8.72 m³ / h. This means that the air leakage is 0.6 m³ / h, accounting for 6.43% of the total air volume. This ensures sufficient airflow above the ice box, enabling rapid ice production.

[0192] Figure 12 for Figure 5 Side view of Figure 13 for Figure 12 A partial enlarged view of point C in the middle.

[0193] See also Figure 12 and Figure 13 In some embodiments, along the depth direction of the box body 100 , the height of the top wall of the air outlet structure 510 decreases from the end away from the air guide 1400 to the end close to the air guide 1400 .

[0194] Specifically, the height of the top wall of the air outlet structure 510 may gradually decrease.

[0195] It can be understood that the condensation on the top wall of the air outlet structure 510 can slide along the top of the air outlet structure 510 into the air guide cavity 1410 and then be blown away by the cold air in the air guide cavity 1410, thereby effectively avoiding ice formation.

[0196] In some embodiments, along the depth direction of the box body 100 , the height of the bottom wall of the air outlet structure 510 increases from an end away from the air guide 1400 to an end close to the air guide 1400 .

[0197] Specifically, the height of the bottom wall of the air outlet structure 510 may gradually increase.

[0198] It can be understood that the condensation on the bottom wall of the air outlet structure 510 can slide along the bottom of the air outlet structure 510 to the bottom of the air outlet structure 510, thereby effectively avoiding accumulation between the outer wall of the air outlet structure 510 and the inner wall of the air guide 1400, thereby effectively avoiding ice formation.

[0199] See also Figure 11 As shown, in some embodiments, along the depth direction of the box body 100 , the height of the inner bottom wall of the air guide 1400 increases from the end close to the air outlet structure 510 to the end away from the air outlet structure 510 .

[0200] Specifically, the height of the inner bottom wall of the air guide 1400 may gradually increase.

[0201] It can be understood that the condensation on the inner bottom wall of the air guide 1400 can slide along the inner bottom wall of the air guide 1400 to the outside of the air guide 1400, thereby effectively avoiding accumulation between the outer wall of the air outlet structure 510 and the inner wall of the air guide 1400, thereby effectively avoiding ice formation.

[0202] It should be noted that the depth direction is the direction indicated by the Y axis in the figure, and the height direction is the direction indicated by the Z axis in the figure.
