[0036] The present invention will be described in detail below in conjunction with the specific embodiments shown in the accompanying drawings. However, these embodiments do not limit the present invention, and any structural, methodological, or functional changes made by a person skilled in the art based on these embodiments are all within the scope of protection of the present invention.

[0037] Reference Figure 1 , Figure 2 In one embodiment of the present invention, a refrigerator 100 is provided, which may include a housing 1, a storage chamber 2 formed in the housing 1, a storage chamber door 3 for opening and closing the storage chamber 2, and a dispenser chamber 6 disposed in the storage chamber door 3. The storage chamber 2 may be a refrigerator compartment, a freezer compartment, a temperature-changing chamber, etc. Preferably, the storage chamber 2 is a refrigerator compartment.

[0038] The dispenser chamber 6 is provided with a water outlet 62 or an ice outlet 61. The dispenser chamber 6 opens outward.

[0039] In this embodiment, the up-down direction may refer to the height direction of the cabinet 1, the front-back direction may refer to the depth direction of the cabinet 1, and the left-right direction may refer to the width direction of the cabinet 1. Taking the user as a reference, when the user uses the refrigerator, the side close to the user may be the front side, and the side away from the user may be the back side. The refrigerator 100 may also include a refrigeration system, which may include an evaporator, a condenser, a compressor, etc. The evaporator may be arranged at the back of the storage chamber 2 to cool the storage chamber 2 by direct cooling. Of course, the evaporator may also be arranged in the evaporator chamber, and a refrigerated air inlet duct and a refrigerated air return duct that allow cold air to circulate may be provided between the storage chamber 2 and the evaporator chamber to achieve cooling of the storage chamber 2 by air cooling.

[0040] The refrigerator 100 may further include a sub-door 4 disposed outside the storage chamber door 3. A heat-insulating material may be disposed inside the sub-door 4. The sub-door 4 may be used to open and close the opening of the dispenser chamber 6. When the sub-door 4 closes the opening of the dispenser chamber 6, the dispenser chamber 6 can form a relatively closed space. The sub-door 4 closing the dispenser chamber 6 can also clean the dispenser chamber 6 and prevent dust from the outside from contaminating the dispenser chamber 6.

[0041] Furthermore, in the present embodiment, the refrigerator 100 may further include an ice-making chamber 5 provided on the storage chamber door 3, and an ice-making door 7 provided on the storage chamber door 3 and used to open and close the opening of the ice-making chamber 5. In other embodiments, the ice-making door 7 may also be installed on the auxiliary door 4, and it is sufficient to open and close the ice-making chamber 5. The ice-making chamber 5 opens outward, and a heat-insulating material is provided inside the ice-making door 7. By providing the ice-making door 7 with the heat-insulating material, the cold transfer between the ice-making chamber 5 and the external space can be isolated, and the cold air leakage of the ice-making chamber 5 can be avoided.

[0042] Furthermore, in this embodiment, the auxiliary door 4 can be arranged outside the ice-making door 7. When the auxiliary door 4 is in a closed state, the auxiliary door 4 can shield the ice-making door 7. Such an arrangement can ensure the cleanliness of the ice-making door 7, prevent the external environment from polluting the ice-making door 7, and further isolate the cold transfer between the ice-making chamber 5 and the external space through the auxiliary door 4, prevent the cold air in the ice-making chamber 5 from leaking, and in addition, can make the appearance of the storage chamber door 3 more simple and neat.

[0043] Furthermore, in the present embodiment, an ice maker 51 and an ice storage box 52 placed below the ice maker 51 may be provided in the ice making chamber 5 , and an ice guide channel 31 may be provided between the ice outlet 61 in the dispenser chamber 6 and the ice storage box 52 .

[0044] The ice cubes stored in the ice storage box 52 can be discharged from the ice outlet 61 through the ice guide channel 31. The user can take the ice cubes through the ice outlet 61 of the dispenser chamber 6 without opening the storage chamber door 3 and the ice making door 7, which is convenient for the user to take ice cubes in daily life.

[0045] The ice storage box 52 can be removably disposed below the ice maker 51. When the user needs to take a large amount of ice cubes, the user can open the ice making door 7 and take out the ice storage box 52 to take the ice cubes.

[0046] Furthermore, in this embodiment, the storage chamber door 3 may include a door shell 32 and a door lining 33 that are arranged opposite to each other. A heat-insulating material may be arranged between the door shell 32 and the door lining 33. In this way, the cold transfer between the storage chamber 2 and the external environment can be isolated by closing the storage chamber door 3, thereby preventing the cold leakage in the storage chamber 2.

[0047] The dispenser chamber 6 may be provided in the door shell 32. The dispenser chamber 6 may be formed by the door shell 32 being recessed toward the door lining 33. The ice making chamber 5 may also be provided in the door shell 32. The ice making chamber 5 may also be recessed toward the door lining 33 by the door shell 32. The dispenser chamber 6 may be provided below the ice making chamber 5.

[0048] Furthermore, in this embodiment, the refrigerator 100 supplies cold to the distribution chamber 6. Preferably, the temperature of the distribution chamber 6 is a refrigeration temperature that can provide a refrigerated environment. For example, the temperature of the distribution chamber 6 can be maintained between 1-5 degrees Celsius.

[0049] There are many ways for the refrigerator 100 to supply cold to the distributor chamber 6. Preferably, the refrigerator supplies cold to the distributor chamber 6 through the storage chamber 2, and utilizes the coldness of the storage chamber 2 to cool the distributor chamber 6 and reduce the temperature of the distributor chamber 6.

[0050] Reference Figure 1 and Figure 2 Preferably, in this embodiment, the wall of the distributor chamber 6 may be provided with an air inlet 63 and an air return port 64 communicating with the cold air of the storage chamber 2. The cold air in the storage chamber 2 may enter the distributor chamber 6 through the air inlet 63. The cold air in the distributor chamber 6 may enter the storage chamber 2 through the air return port 64.

[0051] By arranging an air inlet 63 and an air return port 64 on the wall of the distributor chamber 6 which are in communication with the cold air of the storage chamber 2 , cold air circulation between the storage chamber 2 and the distributor chamber 6 can be achieved, thereby utilizing the cold air in the storage chamber 2 to cool the distributor chamber 6 .

[0052] In addition, since the distributor chamber 6 is arranged on the storage chamber door 3 and is close to the storage chamber 2, this cooling method of the distributor chamber 6 can ensure the cooling effect of the distributor chamber 6, avoid the air duct arrangement of the distributor chamber 6 being too complicated, and achieve the purpose of lowering the temperature of the distributor chamber 6 while having a simpler structure and being easy to implement.

[0053] Furthermore, in this embodiment, a heat-insulating material may be provided between the rear wall of the distributor chamber 6 and the door lining 33. This arrangement enables the temperature distribution in the distributor chamber 6 to be more uniform. The distributor chamber 6 is connected to the storage chamber 2 for cold capacity, and a refrigeration and fresh-keeping environment similar to that of the storage chamber 2 can be formed. The distributor chamber 6 can be used to place a kettle to cool the water in the kettle, so that the user can take cold water daily. The distributor chamber 6 can also be used to provide a certain space for placing items, so that the user can use the distributor chamber 6 to store a certain amount of items without opening the storage chamber door 3, which can increase the storage space of the refrigerator 100 and facilitate the user's daily use.

[0054] Reference Figures 1 to 4 The refrigerator 100 further includes a sealing strip 8, which at least closes around the periphery of the ice-making door 7 when the secondary door 4 is in a closed state. The sealing strip 8 seals at least the gap between the front wall of the ice-making chamber 5 and the secondary door 4 at the periphery of the ice-making door 7, and prevents the cold air in the dispenser chamber 6 from flowing between the ice-making door 7 and the secondary door 4.

[0055] The ice-making door may include an ice-making door shell 71 and an ice-making door lining 72 which are arranged opposite to each other. A heat-insulating space may be formed between the ice-making door shell 71 and the ice-making door lining 72, and an ice-making heat-insulating material 73 may be arranged in the heat-insulating space.

[0056] The ice-making door 7 and the ice-making chamber 5 may be provided with a door seal of the ice-making door 7. When the ice-making door 7 is in a closed state, the door seal of the ice-making door 7 may be a closed type surrounding the opening of the ice-making chamber 5. The door seal of the ice-making door 7 may seal the gap between the ice-making door 7 and the ice-making chamber 5 to prevent the cold air in the ice-making chamber 5 from leaking.

[0057] However, when the ice-making door 7 is in a closed state, since the temperature in the ice-making chamber 5 is relatively low, generally about 10 degrees below zero, it is inevitable that some cold energy will be transmitted to the outside of the ice-making door 7 through the ice-making door 7 or the seal of the ice-making door 7, and the temperature of the ice-making door 7, especially the upper, lower, left and right side walls of the ice-making door 7, will be relatively low, thereby causing condensation on the surface of the ice-making door. The auxiliary door 4 shields the outside of the ice-making door 7, and the ice-making door 7 is placed in the sealing area formed by the seal 8, which is equivalent to adding a heat-insulating layer on the outside of the ice-making door 7, improving the heat-insulating effect of the ice-making chamber 5, reducing the leakage of cold air in the ice-making chamber 5, reducing the thickness of the ice-making door 7, and being conducive to realizing the thin and light design of the ice-making door 7. At the same time, it can prevent the ice-making door 7 from directly contacting the external environment, and can effectively prevent condensation on the surface of the ice-making door 7.

[0058] Since the temperature of the dispenser chamber 6 is generally much lower than that of the ice-making chamber 5, and the humidity in the dispenser chamber 6 is generally relatively high, by setting the sealing strip 8 to prevent the cold air in the dispenser chamber 6 from flowing between the ice-making door 7 and the secondary door 4, it can effectively prevent the air in the dispenser chamber 6 from causing condensation on the ice-making door 7 and effectively avoid the appearance of condensation on the surface of the ice-making door 7.

[0059] Refer to Figures 1 to 4 , further, in this embodiment, there may be a gap between the ice-making door 7 and the secondary door 4.

[0060] The front surface of the ice-making door 7 and the rear surface of the secondary door 4 are not closely attached, but are spaced apart by a certain distance. This setting can facilitate the opening and closing of the ice-making door 7 and the secondary door 4 and avoid interference between the ice-making door 7 and the secondary door 4.

[0061] The sealing strip 8 can be a refrigerator door seal with an airbag in the middle made of existing materials such as PVC. Under the pressure of both sides of the front wall of the storage chamber door 3 and the rear wall of the secondary door 4, the sealing strip 8 will undergo a certain degree of deformation, so that both sides are closely attached to the front wall of the storage chamber door 3 and the rear wall of the secondary door 4 respectively, thereby realizing the sealing between the ice-making door 7 and the dispenser chamber 6 in the sealed area and avoiding contact between the ice-making door 7 and the dispenser chamber 6 and the outside world when the secondary door 4 is in the closed state.

[0062] Setting a certain amount of gap between the ice-making door 7 and the secondary door 4 can also ensure that the sealing strip 8 has enough deformation space and ensure the sealing effect of the sealing strip 8.

[0063] Refer to Figure 3 and Figure 4 , when the secondary door 4 is in the closed state, the sealing strip 8 simultaneously and enclosingly surrounds the opening of the dispenser chamber 6, and the sealing strip 8 also seals the gap between the front wall of the dispenser chamber 6 outside the periphery of the opening of the dispenser chamber 6 and the secondary door 4 to prevent the dispenser chamber 6 from directly contacting the external environment.

[0064] Placing the dispenser chamber 6 within the sealed area of the sealing strip 8 can improve the closing effect of the secondary door 4 on the dispenser chamber 6 and avoid the loss of cold in the dispenser chamber 6.

[0065] Refer to Figure 3 and Figure 4 , further, in this embodiment, the sealing strip 8 is generally in the shape of a "曰" character to simultaneously and enclosingly surround the openings of the ice-making door 7 and the dispenser chamber 6 respectively.

[0066] Specifically, the sealing strip 8 can be set to be composed of a U-shaped sealing strip 81 connected end to end and a separate I-shaped sealing strip 82. The U-shaped sealing strip 81 can surround the outside of the opening of the ice-making door 7 and the dispenser chamber 6 to prevent the ice-making door 7 or the dispenser chamber 6 from contacting the external environment. The I-shaped sealing strip 82 can be arranged on the front wall of the partition wall 321 between the ice-making door 7 and the dispenser chamber 6 to block the cold air in the dispenser chamber 6 from overflowing to the front side of the ice-making door 7 through the opening.

[0067] With such a setting, the sealing of both the ice-making door 7 and the dispenser chamber 6 can be achieved simultaneously, effectively preventing the cold air in the dispenser chamber 6 from entering between the ice-making door 7 and the secondary door 4. It can simplify the structure and installation of the sealing strip 8 and facilitate the mutual cooperation between the secondary door 4 and the storage chamber door 3.

[0068] Referring to Figure 3 and Figure 5 , the secondary door 4 can be recessed to form a mounting groove 44 that cooperates with the sealing strip 8, and the sealing strip 8 is inserted into the mounting groove 44. With such a setting, the structure is simple and the installation is convenient. Of course, in other embodiments of the present invention, the sealing strip 8 can also be installed on the front wall of the storage chamber door 3.

[0069] Referring to Figure 3 and Figure 5 , further, in this embodiment, the heat-insulating material of the secondary door 4 can include a VIP board 43 and a foamed heat-insulating material. The VIP board 43 is arranged at the corresponding position of the dispenser chamber 6 of the secondary door 4. The foamed heat-insulating material is foamed and filled around the VIP board 43 and at the corresponding position of the ice-making chamber 5 of the secondary door 4.

[0070] The secondary door can include oppositely arranged secondary door shells 41 and secondary door linings 42. The secondary door shells 41 and the secondary door linings 42 form a heat-insulating space. The VIP board 43 can be arranged at the corresponding position of the dispenser chamber 6 in the heat-insulating space, and the foamed heat-insulating material can be foamed and filled in the remaining positions of the heat-insulating space.

[0071] Specifically, the mounting groove 44 can be recessed from the secondary door lining 42 towards the secondary door shell 41. The mounting groove 44 can be generally in the shape of a Chinese character 'Ri'. The mounting groove 44 can include a U-shaped sealing groove 441 that cooperates with the U-shaped sealing strip 81, and can also include an I-shaped sealing groove 442 that cooperates with the I-shaped sealing strip 82. The U-shaped sealing groove 441 and the I-shaped sealing groove 442 can communicate with each other.

[0072] Since the ice-making chamber 5 has been thermally insulated by the heat-insulating material inside the ice-making door 7, the thermal insulation requirement for the area of the secondary door 4 corresponding to the ice-making door 7 is relatively low. The dispenser chamber 6 is only thermally insulated by the heat-insulating material inside the secondary door 4, so the thermal insulation requirement for the area of the secondary door 4 corresponding to the dispenser chamber 6 is relatively high.

[0073] Compared with the foam material, the VIP panel 43 is thinner and has better thermal insulation effect. The VIP panel 43 can be set at the corresponding position of the distributor chamber 6 of the sub-door 4, which can improve the thermal insulation effect of the distributor chamber 6 and avoid cold air leakage in the distributor chamber 6. Different thermal insulation materials are set in different areas of the sub-door 4, and the foamed thermal insulation material is filled around the VIP panel 43 to fix the VIP panel 43. This can ensure the thermal insulation effect of the sub-door 4, simplify the structural design of the sub-door 4, reduce the production cost of the sub-door 4, and reduce the thickness of the sub-door 4.

[0074] Preferably, in this embodiment, air cooling can be used to cool the storage chamber 2 and promote uniform temperature distribution in the storage chamber 2, that is, by setting a refrigeration fan to make cold air flow in the storage chamber 2. The refrigeration fan can be set in the air duct between the storage chamber 2 and the evaporator chamber, and can also be set in the storage chamber 2.

[0075] By providing a refrigeration fan to promote the air flow in the storage room 2, the cold air circulation and cold energy exchange between the storage room 2 and the distributor room 6 can also be promoted, and the cooling efficiency of the distributor room 6 can be improved.

[0076] Reference Figure 3 and Figure 6 Further, in this embodiment, the refrigerator 100 may further include a filter 9 disposed on the storage chamber door 3. The filter 9 may be opposite to the air inlet 63 and may be used to filter the cold air from the storage chamber 2 into the dispenser chamber 6.

[0077] The storage room 2 generally has a large storage space and stores many items, such as fruits, vegetables, meat, etc., so it is easy for the storage room 2 to produce odor. The distributor room 6 is generally used to take ice or water, and generally does not have odor. Since the cold air between the storage room 2 and the distributor room 6 circulates through the air inlet 63 and the return air outlet 64 on the distributor room 6, the odor in the storage room 2 can easily flow into the distributor room 6 and mix with the odor of the distributor room 6, causing the distributor room 6 to also have odor.

[0078] By arranging a filter element 9 on the storage chamber door 3 for filtering the cold air from the storage chamber 2 entering the dispenser chamber 6, it is possible to effectively prevent the odor in the storage chamber 2 from flowing into the dispenser chamber 6, and to prevent the storage chamber 2 and the dispenser chamber 6 from mixing odors. This improves the cooling efficiency of the dispenser chamber 6 while ensuring the cleanliness of the internal environment and odor of the dispenser chamber 6, thereby improving the user experience of the dispenser chamber 6.

[0079] The filter element 9 is arranged opposite to the air inlet 63. Specifically, the filter element 9 can be arranged at the front side, the rear side, or the inner side of the air inlet 63, as long as the filter element 9 can fully cover the air inlet 63.

[0080] Such a configuration can ensure the filtering effect of the filter element 9, improve the filtering efficiency, and fully filter the cold air from the storage chamber 2 entering the dispenser chamber 6, thereby avoiding poor odor removal effect due to part of the cold air not being filtered out. It can also facilitate the installation and setting of the filter element 9, avoid the filter element 9 being too large in size, and reduce the space occupied by the filter element 9 on the storage chamber door 3.

[0081] Reference Figure 3 and Figure 8 The refrigerator 100 may further include a fan 11 disposed on the storage chamber door 3. The fan 11 may be opposite to the air inlet 63 and used to promote the cold air in the storage chamber 2 to enter the dispenser chamber 6 from the air inlet 63.

[0082] The fan 11 and the air inlet 63 are arranged opposite to each other. Specifically, the fan 11 can be arranged at the front side, the rear side, or the inner side of the air inlet 63 .

[0096] The rear surface of the brake plate 131 may be provided with a micro switch, and the front surface of the grille of the air inlet 63 may be provided with a protrusion that cooperates with the micro switch. The rear surface of the brake plate 131 may also be provided with an elastic member, and the rear surface of the elastic member may abut against the front surface of the rear wall of the accommodating space 601.

[0097] When the brake plate 131 swings backward due to external force, the elastic part is compressed, the micro switch abuts against the protrusion on the front surface of the air inlet 63 grille, and the manual water outlet 621 is opened; when the external force on the brake plate 131 disappears, the elastic part stretches to reset the brake plate 131, the micro switch no longer contacts the protrusion on the front surface of the air inlet 63 grille, and the manual water outlet 621 is closed.

[0098] The middle portion of the brake plate 131 can be recessed toward the interior of the accommodating space 601, and the left edge, right edge and lower edge of the brake plate 131 can be inclined away from the rear wall of the distributor chamber 6, so that the left gap, right gap and lower gap between the brake plate 131 and the wall of the distributor chamber 6 gradually increase along the flow direction of the cold air entering from the air inlet 63, so as to facilitate the flow of cold air and better play a role in diverting and guiding the cold air.

[0099] Such an arrangement enables the brake member 13 to block the air inlet 63 from the front side, thereby realizing a concealed arrangement of the air inlet 63. It also enables the brake member 13 to divert and guide the cold air flowing in from the air inlet 63, thereby making the wind circulation in the entire distributor chamber 6 more reasonable and the temperature distribution in the distributor chamber 6 more uniform.

[0100] Reference Figure 1 , Figure 2 and Fig.12 , ( Fig.12 The dotted rectangular frame in the figure is used to indicate the location of the automatic water filling kettle 14. Further, in this embodiment, the dispenser chamber 6 is provided with an automatic water outlet 622 and a removable automatic water filling kettle 14 placed below the automatic water outlet 622.

The water temperature detection device can also be arranged on the automatic water filling kettle 14, for example, arranged in the automatic water filling kettle 14, or arranged to be attached to the automatic water filling kettle 14, so as to detect the water temperature of the automatic water filling kettle 14.

[0110] Furthermore, in this embodiment, the refrigerator 100 may further include a display device. The display device may be in communication connection with the control module. The display device may include a display screen. Under the control of the control module of the refrigerator, the display device may display the water temperature of the automatic water filling kettle 14 detected by the water temperature detection device, so that the user may accurately and timely understand the water temperature in the automatic water filling kettle 14 without opening the door.

[0111] Reference Fig.16 Furthermore, in this embodiment, the refrigerator 100 may further include a water quantity detection device. The water quantity detection device is used to detect the water quantity of the automatic water filling kettle 14. The water quantity detection device can be connected to the control module of the refrigerator for communication, and transmit the detected water quantity information of the automatic water filling kettle 14 to the control module.

[0112] Under the control of the control module, the display device can display the water level of the automatic water filling kettle 14 detected by the water level detection device, so that the user can accurately and timely understand the water level in the automatic water filling kettle 14 without opening the refrigerator door.

[0113] Preferably, in this embodiment, the water level detection device may include a first liquid level sensor 121, a second liquid level sensor 122, and a third liquid level sensor 123. The height of the first liquid level sensor 121 may be located at the upper part of the automatic water filling kettle 14, and the first liquid level sensor 121 is located below the water injection port 141 of the automatic water filling kettle 14. The water injection port 141 cooperates with the automatic water outlet 622. The height of the second liquid level sensor 122 may be located in the middle of the automatic water filling kettle 14. The height of the third liquid level sensor 123 may be located at the lower part of the automatic water filling kettle 14.

[0114] In this embodiment, the water amount detection device can be arranged in the distribution chamber. The water amount detection device can be arranged in a non-contact manner with the automatic water filling kettle 14. Of course, in other embodiments of the present invention, the water amount detection device can also be arranged on the automatic water filling kettle 14, for example, arranged in the automatic water filling kettle 14, or arranged to be attached to the automatic water filling kettle 14, so as to detect the water amount of the automatic water filling kettle 14.

[0115] When the water level in the automatic water filling kettle 14 reaches the height of the first liquid level sensor 121, the first liquid level sensor 121, the second liquid level sensor 122, and the third liquid level sensor 123 can all detect that there is water in the automatic water filling kettle 14 and send a signal to the control module. The control module can control the display device to display whether the water level in the automatic water filling kettle 14 is too much or full according to the signal transmitted by the water level detection device.

[0116] When the water level in the automatic water filling kettle 14 reaches or exceeds the height of the second liquid level sensor 122 and is lower than the height of the first liquid level sensor 121, the second liquid level sensor 122 and the third liquid level sensor 123 can detect that there is water in the automatic water filling kettle 14 and send a signal to the control module. The control module can control the display device to display that the water level in the automatic water filling kettle 14 is medium according to the signal transmitted by the water level detection device.

[0117] When the amount of water in the automatic water filling kettle 14 is lower than the height of the second liquid level sensor 122, only the third liquid level sensor 123 can detect that there is water in the automatic water filling kettle 14 and send a signal to the control module. The control module can control the display device to display that the amount of water in the automatic water filling kettle 14 is a small amount according to the signal transmitted by the water level detection device.

[0118] In addition, when the first liquid level sensor 121 detects that there is water in the automatic water filling kettle 14, the automatic water outlet 622 can be controlled to be closed to prevent the automatic water outlet 622 from continuing to inject water into the automatic water filling kettle 14 and causing the water in the automatic water filling kettle 14 to overflow.

[0119] Further, in this embodiment, a bracket may be provided in the dispenser chamber 6. The bracket may extend along the height direction of the automatic water filling kettle 14. The bracket may be provided in cooperation with the side wall of the automatic water filling kettle 14. The first liquid level sensor 121, the second liquid level sensor 122, and the third liquid level sensor 123 may all be provided on the bracket.

[0120] The water temperature detection device can also be arranged on support. In addition, the water quantity detection device can be arranged on support away from the automatic water filling kettle 14 sides, to realize the hidden arrangement of the water quantity detection device, while avoiding the water quantity detection device water inlet as far as possible.

[0121] In other embodiments of the present invention, the water volume detection device may only include a liquid level sensor. The water volume detection device may be disposed on the upper portion of the automatic water filling kettle 14 and below the water filling port 141 of the automatic water filling kettle 14 .

[0122] When the water level detection device detects that there is water in the automatic water filling kettle 14, the control module can control the display device to display that the water level in the automatic water filling kettle 14 is full according to the signal transmitted by the water level detection device. When the water level detection device detects that there is water in the automatic water filling kettle 14, the automatic water outlet 622 can be controlled to be closed to prevent the automatic water outlet 622 from continuing to inject water into the automatic water filling kettle 14 and causing the water in the automatic water filling kettle 14 to overflow.

[0123] The bottom surface of the placement groove 66 may be recessed downward to form a water storage groove 67. If the water in the automatic water filling kettle 14 overflows, it may first flow downward into the placement groove 66, then flow in the placement groove 66 and accumulate in the water storage groove 67. The dispenser chamber 6 may be provided with a water storage detection device at the water storage groove 67. The water storage detection device may be used to detect whether there is water in the water storage groove 67. The water storage detection device 67 may be a sensor capable of detecting whether there is water.

[0124] When the kettle detection module detects that the automatic water filling kettle 14 is placed in the placement slot 66, and the water storage detection device does not detect that there is water in the water storage slot 67, and the water quantity detection device detects that the water level in the automatic water filling kettle 14 has not reached the preset water level, the control module can control the automatic water outlet 622 to open to inject water into the automatic water filling kettle 14 until the water level in the automatic water filling kettle 14 reaches the preset water level.

[0125] Such an arrangement can realize automatic water filling into the automatic water filling kettle 14. The cold air in the dispenser chamber 6 can cool the water in the automatic water filling kettle 14. The user can directly take out the automatic water filling kettle 14 from the dispenser chamber 6 for use, which can facilitate the user to take a large amount of ice water, save the user's water fetching time, and improve the user's experience.

[0126] Reference Figure 1 , Figure 2 and Fig.12Furthermore, in this embodiment, the manual water inlet can be set close to the right side of the distributor chamber 6, and the automatic water outlet 622 can be set close to the left side of the distributor chamber 6.

[0127] A portion of the cold air entering from the air inlet 63 can flow into the return air outlet 64 from the right side gap between the brake part 13 and the rear wall of the dispenser chamber 6, along the rear wall of the dispenser chamber 6, the right side wall of the dispenser chamber 6, the auxiliary door 4, the front side of the automatic water filling kettle 14, the left side of the automatic water filling kettle 14 (the left side wall of the dispenser chamber 6, the left side wall of the placement space 65), and the rear side of the automatic water filling kettle 14 (the rear wall of the dispenser chamber 6, the rear wall of the placement space 65).

[0128] Another part of the cold air entering from the air inlet 63 can flow into the return air outlet 64 from the left gap between the brake part 13 and the rear wall of the dispenser chamber 6, along the rear wall of the dispenser chamber 6, the right side of the automatic water filling kettle 14 (the right side wall of the placement space 65), and the rear side of the automatic water filling kettle 14 (the rear wall of the placement space 65).

[0129] Such arrangement enables the brake member 13 and the automatic water filling kettle 14 to divert and guide the cold air flowing in the dispenser chamber 6, making the wind circulation in the entire dispenser chamber 6 more reasonable and the temperature distribution in the dispenser chamber 6 more uniform.

[0130] Furthermore, in one embodiment of the present invention, the refrigerator 100 further includes a door lock. The door lock may be provided on the secondary door 4, and the door lock may be used to lock the secondary door 4 in a position to close the dispenser chamber 6. The door lock may be a push-type door lock, and when the door lock is pressed, the door lock opens to enable the secondary door 4 to be opened.

[0131] The refrigerator 100 may further include a pressure detection device, which may be provided in conjunction with a door lock, and is used to detect whether the door lock is pressed, so that the refrigerator 100 can control the opening and closing of the automatic water outlet 622 according to a signal output by the pressure detection device.

[0132] When the pressure detection device detects that the door lock is pressed, it indicates that the user is opening the auxiliary door 4 and the user wants to use the dispenser chamber 6. The control module of the refrigerator can control the automatic water outlet 622 to close according to the signal transmitted by the pressure detection device, so that the automatic water outlet 622 stops injecting water into the automatic water filling kettle 14. In this way, when the auxiliary door 4 is opened, the automatic water outlet 622 is always closed to prevent water from splashing out of the automatic water outlet 622, or the automatic water outlet 622 injects water into the automatic water filling kettle 14, which affects the user's use of the dispenser chamber 6, such as taking the automatic water filling kettle 14.

[0133] Specifically, the pressure detection device may be a pressure sensor, or an electrical switch triggered when the door lock is pressed, which can output a corresponding signal to the control module of the refrigerator when the door lock is pressed.

[0134] Of course, in other embodiments of the present invention, the door lock may be an automatic door lock. The user does not need to manually press the door lock, and can input a door lock opening command to the refrigerator through a display screen or voice or the like. When the refrigerator receives a command input by the user to open the secondary door 4, the control module of the refrigerator can first detect whether the automatic water outlet 622 is closed. If the automatic water outlet 622 is in an open state, the automatic water outlet 622 can be controlled to be closed first, and then the door lock can be controlled to be opened, so that the automatic water outlet 622 is closed before the secondary door 4 is opened, and the automatic water outlet 622 is ensured to be in a closed state when the secondary door 4 is opened.

[0135] Reference Figure 3 , Fig.12 and Fig.15 Furthermore, in the present embodiment, the door lining 33 is recessed toward the air inlet 63 to form a mounting portion 331 .

The opening of the installation portion 331 toward the air inlet 63 can be larger than the air inlet 63, so that the fan 11 can blow the cold air in the storage chamber 2 into the air inlet 63. Such an arrangement can ensure the mutual cooperation between the fan 11 and the air inlet 63, and can facilitate the installation of the fan 11.

[0137] Reference Figure 3 , Figure 8 , Fig. 9 and Fig.12 Further, in this embodiment, a cover 12 for shielding the mounting portion 331 may be provided on the inner side of the door lining 33. The inner side of the door lining 33 is the side of the door lining 33 that faces the opening of the storage chamber 2.

[0153] In actual use, the user can remove the cover body 12 together with the fan 11 from the mounting portion 331 from the side of the door lining 33, and then take out the bracket 10 and the filter 9 from the opening on the side of the air inlet 63 of the mounting portion 331. When installing again, the user can first install the bracket 10 and the filter 9 from the opening on the side of the air inlet 63 of the mounting portion 331, so that the bracket 10 abuts against the rear wall of the distributor chamber 6, and then install the interconnected cover body 12 and the fan 11 into the mounting portion 331 together, so that the fan 11 abuts against the bracket 10, and the cover body 12 and the mounting portion 331 are mutually engaged, so as to achieve mutual cooperation and stable installation of the cover body 12, the fan 11, the bracket 10, and the filter 9. Such a configuration has a simple structure and is easy to disassemble and assemble.

[0154] Furthermore, the bracket 10 can at least partially extend into the opening on the side of the air inlet 63 of the mounting portion 331. This arrangement can position and limit the bracket 10, facilitate the abutment and cooperation between the bracket 10 and the fan 11, and facilitate the disassembly and assembly of the bracket 10.

[0155] Reference Fig.10 Furthermore, in this embodiment, the rear wall of the distributor chamber 6 can extend toward the door lining 33 to form a first flange 68, and the first flange 68 can close around the air inlet 63. The first flange 68 can be closed around the first seal, and the front wall of the mounting portion 331 is connected to the first seal to prevent the insulation material between the rear wall of the distributor chamber 6 and the door lining 33 from entering the air inlet 63 or the mounting portion 331.

[0156] The rear wall of the distributor chamber 6 can extend toward the door lining 33 to form a second flange 69, and the second flange 69 can surround the return air outlet 64 in a closed manner. The second flange 69 can be externally closed and surrounded by a second seal, and the front wall of the door lining 33 is connected to the second seal to prevent the insulation material between the rear wall of the distributor chamber 6 and the door lining 33 from entering the return air outlet 64 or the inner side of the door lining 33.

[0157] The first sealing member and the second sealing member may both be sealing sponges. The door lining may be provided with an opening corresponding to the return air port 64. The opening corresponding to the return air port 64 provided on the door lining is placed inside the second flange 69. This arrangement can prevent the insulation material from overflowing from the interval space between the rear wall of the distributor chamber 6 and the door lining 33 to the air inlet 63 or the inside of the mounting portion 331 or the inside of the door lining 33 when the insulation material is foamed and filled.
