Description

Technical Field

[0001] This invention relates to the field of refrigeration equipment, and more particularly to a refrigerator. Background Technology

[0002] As people's living standards continue to improve, refrigerators are becoming more and more functional. For example, refrigerators can be equipped with a water supply system that uses a filter to filter external water sources and supplies the filtered water to a distributor and / or ice maker to meet different usage needs.

[0003] In related technologies, when installing a water supply system, the filter is typically fixed to a mounting base, which is then placed inside the refrigeration room, for example, between a drawer and its inner liner. However, because the mounting base and the drawer are not compatible, placing them adjacent to each other results in wasted space inside the refrigeration room. Summary of the Invention

[0004] The purpose of this invention is to provide a refrigerator that avoids wasting indoor space in the refrigeration room.

[0005] To achieve one of the above-mentioned objectives, one embodiment of the present invention provides a refrigerator, comprising:

The clearance block passes through the clearance groove along a second direction to disengage the mounting base from the fixing bracket. The first direction and the second direction are set at a certain angle.

[0014] As a further improvement of one embodiment of the present invention, the fixing device includes a first docking structure and a second docking structure that allow the mounting base and the fixing bracket to slide and engage along a first direction. The first docking structure and the second docking structure are arranged opposite each other along a third direction, and the third direction is arranged at a certain angle to the first direction.

[0015] As a further improvement of one embodiment of the present invention, the fixing device further includes an adjusting column that connects to the mounting base and abuts against the inner liner, the adjusting column being located on the side of the mounting base away from the fixing bracket along a second direction.

[0016] As a further improvement of one embodiment of the present invention, the water supply system includes a kettle connected to a filter, and the mounting base has a first cavity for receiving the filter and a second cavity for receiving the kettle, the first cavity being located above the second cavity.

[0031] The present invention will now be described in detail with reference to the specific embodiments shown in the accompanying drawings. However, these embodiments do not limit the present invention, and any structural, methodological, or functional modifications made by those skilled in the art based on these embodiments are included within the scope of protection of the present invention.

[0032] It should be understood that terms such as “having,” “comprising,” and “including” as used herein do not exclude the presence or addition of one or more other elements or combinations thereof.

[0033] It should be understood that terms such as "upper," "lower," "outer," and "inner," used herein to indicate spatial relative position, are for illustrative purposes to describe the relationship of one unit or feature relative to another unit or feature as shown in the accompanying drawings. The terms "spatial relative position" may be intended to include different orientations of the equipment in use or operation other than those shown in the figures.

[0034] The device may be oriented in other ways (rotated 90 degrees or otherwise), and the spatially related descriptive terms used herein shall be interpreted accordingly. For ease of description, in the present invention, when the refrigerator is in normal use, the direction facing the ground is downward, and the direction away from the ground is upward; the direction parallel to the ground is horizontal, and the direction perpendicular to the ground is vertical; the side closer to the user is the front side, and the side farther from the user is the rear side.

[0035] In the description of this invention, it should also be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0036] Reference Figure 1 As shown, a refrigerator includes an outer shell 104, an inner liner 101, and an insulation cavity 105. The inner liner 101 has a cooling compartment 102, and the insulation cavity 105 is located between the outer shell 104 and the inner liner 101. The insulation cavity 105 is filled with foam material to insulate the cooling compartment 102. The cooling compartment 102 can be a refrigerator compartment, a variable temperature compartment, or other functional compartment.

[0037] The refrigerator also includes a refrigeration system that provides cooling capacity to the refrigeration compartment 102. The refrigeration system includes a compressor, condenser, capillary tube, evaporator, etc., which are connected by pipes to form a refrigeration circuit.

[0038] In some embodiments, the refrigerator further includes a drawer 20 disposed within the cooling compartment 102. In this embodiment, the drawer 20 is located within the cooling compartment 102 and can exchange heat with the interior of the cooling compartment 102 to cool the items inside the drawer.

[0039] In some embodiments, in conjunction with reference Figure 2 As shown, the refrigerator also includes a water supply system, which includes a filter 301 located in the refrigeration compartment 102, a first water pipe connected to the filter 301, and a protective pipe 303 located in the insulation cavity 105. In this embodiment, the filter 301 is located in the refrigeration compartment 102, which facilitates the maintenance and replacement of the filter 301, such as replacing the filter element. The first water pipe is connected to the water inlet of the filter 301 to introduce external water into the filter 301 for filtration.

[0040] In some embodiments, the first water pipe passes through the protective pipe 303. In this embodiment, the protective pipe 303 is pre-embedded in the insulation cavity 105, that is, at least part of the first water pipe is pre-embedded in the foaming material, thereby protecting the first water pipe passing through the protective pipe 303. Furthermore, the foaming material in the insulation cavity 105 can insulate the first water pipe and prevent condensation from forming on the first water pipe.

[0041] In some embodiments, the refrigerator further includes a fixing device 40, which connects the inner liner 101 and the filter 301. In this embodiment, after the filter 301 is connected to the fixing device 40, it is connected to the inner liner 101 by the fixing device 40, thereby enabling the filter 301 to be installed (e.g., detachably installed) in the refrigeration compartment 102.

[0042] In some embodiments, in conjunction with reference Figure 3 As shown, the fixing device 40 includes a mounting base 401 for connecting the filter 301. In this embodiment, the filter 301 is fixed to the mounting base 401 and secured within the refrigeration compartment 102 by the mounting base 401. The mounting base 401 protects the filter 301 and prevents accidental contact by the user. The filter 301 is connected to the inner liner 101 via the fixing device 40. Compared to directly placing the filter 301 into the refrigeration compartment 102, this method makes it easier to control assembly errors between the mounting base 401 and the drawer 20, such as the gap between them.

[0043] In some embodiments, the drawer 20 has a clearance notch 201 that matches the mounting base 401. In this embodiment, the clearance notch 201 can be provided at the bottom of the drawer 20, for example, formed by recesses on the left and lower sides of the drawer 20, to avoid affecting the access opening at the top of the drawer 20. The inner diameter of the clearance notch 201 matches the outer dimensions of the mounting base 401, which can make full use of the internal space of the refrigeration compartment 102 and avoid mutual interference between the mounting base 401 and the clearance notch 201.

[0044] In other embodiments, the clearance notch 201 may also be provided at the top of the drawer 20.

[0045] In some embodiments, at least a portion of the filter 301 is located within the clearance notch 201. In this embodiment, after the filter 301 is fixed to the mounting base 401, both the filter 301 and the mounting base 401 are located within the clearance notch 201, thereby making full use of the space within the clearance notch 201 and avoiding wasting space between the drawer 20 and the inner liner 101.

[0046] By providing a clearance notch 201 on the drawer 20 that matches the mounting base 401, after the filter 301 is installed in the refrigeration compartment 102 using the mounting base 401, the filter 301 is directly located in the clearance notch 201, which can make full use of the space in the refrigeration compartment 102 and avoid wasting the space in the refrigeration compartment 102.

[0047] In some embodiments, the fixing device 40 includes a fixing bracket 402 connecting the inner liner 101 and the mounting base 401. In this embodiment, the mounting base 401 is connected to the inner liner 101 by the fixing bracket 402, so that the mounting base 401 can be removed from the refrigeration compartment 102 independently without removing the fixing bracket 402, which facilitates the installation and removal of the filter 301.

[0048] In some embodiments, the fixing bracket 402 and the drawer 20 are at least connected to the same side wall of the inner liner 101. In this embodiment, the fixing bracket 402 and the drawer 20 share the same side wall of the inner liner 101 as an assembly reference, which improves the assembly accuracy between the mounting base 401 and the drawer 20 (i.e., the clearance notch 201) and avoids interference between the mounting base 401 and the drawer 20. The side wall of the inner liner 101 can be the left side wall 1011, the right side wall, etc.

[0049] For example, the fixing bracket 402 and the drawer 20 are connected to the same side wall of the inner liner 101. The fixing bracket 402 is connected to the left side wall 1011 of the inner liner 101, and the drawer 20 is slidably connected to the left side wall 1011 and the right side wall of the inner liner 101, both of which are connected to the left side wall 1011, so that the mounting bracket 401 and the drawer 20 slide in the same direction (e.g., the front-to-back direction).

[0050] In other embodiments, both the fixing bracket 402 and the drawer 20 are connected to two identical side walls of the inner liner 101. For example, the fixing bracket 402 is connected to the left side wall 1011 and the right side wall of the inner liner 101, and the drawer 20 is slidably connected to the left side wall 1011 and the right side wall of the inner liner 101. Both are connected to the left side wall 1011 and the right side wall, which also allows the mounting bracket 401 and the drawer 20 to slide in the same direction (e.g., the front-to-back direction).

[0051] For example, the mounting bracket 402 is fixed to the inner liner 101 (e.g., the left side wall 1011 of the inner liner 101) using fasteners and is located inside the refrigeration compartment 102. The drawer 20 is fixed to the inner liner 101 (e.g., the left side wall 1011 of the inner liner) using a slide rail assembly.

[0052] In some embodiments, the drawer 20 and the inner liner 101 are slidably engaged along a first direction. In this embodiment, the drawer 20 and the inner liner 101 are slidably engaged along a first direction (e.g., the front-to-back direction) to facilitate the user's retrieval and placement of the drawer 20.

[0053] In some embodiments, the fixing device 40 includes a fixing bracket 402 that movably engages with the mounting base 401 along a first direction. In this embodiment, the mounting base 401 and the fixing bracket 402 movably engage along the first direction, enabling a detachable connection. Compared to a non-detachable fixing to the fixing bracket 402, the sliding engagement between the mounting base 401 and the fixing bracket 402 allows for a detachable connection, facilitating the installation and removal of the mounting base 401 (i.e., the filter 301).

[0054] In some embodiments, the mounting base 401 and the fixing bracket 402 are slidably engaged along a first direction. In this embodiment, the mounting base 401 and the fixing bracket 402 are slidably engaged along a first direction (e.g., the front-to-back direction) to facilitate the installation and removal of the mounting base 401.

[0055] It can be seen that the mating direction between drawer 20 and inner liner 101 is the same as the mating direction between mounting base 401 and fixed bracket 402, that is, they both slide along the first direction (e.g., front and back direction) to avoid mutual interference between drawer 20 and mounting base 401 during the mating process.

[0056] Furthermore, the assembly and disassembly processes of drawer 20 and mounting base 401 are independent of each other, which is beneficial for their respective assembly. Since mounting base 401 can move within the clearance notch 201 along the first direction, the filter element can be replaced by sliding mounting base 401 without removing drawer 20.

[0057] In some embodiments, in conjunction with reference Figure 4 and Figure 5 As shown, the fixing device 40 includes a clearance block 403 disposed on one of the mounting base 401 and the fixing bracket 402, and a clearance groove 404 disposed on the other of the mounting base 401 and the fixing bracket 402. In this embodiment, the clearance block 403 may be disposed on the mounting base 401 and the clearance groove 404 may be disposed on the fixing bracket 402. Alternatively, the clearance groove 404 may be disposed on the mounting base 401 and the clearance block 403 may be disposed on the fixing bracket 402.

[0058] In some embodiments, the clearance block 403 passes through the clearance groove 404 along the second direction to disengage the mounting base 401 from the fixed bracket 402. In this embodiment, when the clearance block 403 passes through the clearance groove 404 along the second direction (e.g., from left to right), that is, when the clearance block 403 moves away from the left side wall 1011 along the second direction, the mounting base 401 can disengage from the fixed bracket 402 (e.g., disengage from the sliding fit along the first direction). Thus, by controlling the mounting base 401 to slide a shorter distance along the first direction, that is, controlling the clearance block 403 to be opposite the corresponding clearance groove 404 along the second direction, the mounting base 401 can be disassembled along the second direction, thus eliminating the need to completely disengage the mounting base 401 from the fixed bracket 402 along the first direction, thereby reducing the length of the pipe (e.g., the first water pipe) connected to the filter 301.

[0059] For example, such as Figure 5 By setting multiple clearance slots 404 on the fixed bracket 402, and arranging the multiple clearance slots 404 along the first direction, it is only necessary to control the mounting base 401 to slide a certain distance along the first direction, so that the clearance block 403 can be controlled to be opposite to the corresponding clearance slot 404 along the second direction, thus realizing that the mounting base 401 can be detached along the second direction, making the installation and removal of the mounting base 401 and the fixed bracket 402 along the second direction more convenient.

[0060] In some embodiments, in conjunction with reference Figure 6 As shown, the first direction and the second direction are set at a certain angle. In this embodiment, the first direction can be a front-back direction, and the second direction can be perpendicular to the first direction, such as a left-right direction.

[0061] In some embodiments, the fixing device 40 includes a first mating structure 405 and a second mating structure 406 that allow the mounting base 401 and the fixing bracket 402 to slide along a first direction. In this embodiment, the mounting base 401 and the fixing bracket 402 achieve a sliding fit along the first direction using the first mating structure 405, and / or achieve a sliding fit along the first direction using the second mating structure 406.

[0062] For example, the first docking structure 405 includes a first sliding block 4051 disposed on one of the mounting base 401 and the fixed bracket 402, and a first sliding groove 4052 disposed on the other of the mounting base 401 and the fixed bracket 402. The second docking structure 406 includes a second sliding block 4061 disposed on one of the mounting base 401 and the fixed bracket 402, and a second sliding groove 4062 disposed on the other of the mounting base 401 and the fixed bracket 402.

[0063] In some embodiments, the first mating structure 405 and the second mating structure 406 are disposed opposite each other along a third direction. In this embodiment, compared to the solution where a single mating structure is used to achieve a sliding fit between the mounting base 401 and the fixed bracket 402, as... Figure 6 The first mating structure 405 and the second mating structure 406 are arranged opposite to each other, which improves the stability of the sliding fit between the mounting base 401 and the fixed bracket 402 and avoids misalignment, such as avoiding misalignment relative to a third direction. Furthermore, it also improves the connection strength between the mounting base 401 and the fixed bracket 402.

[0064] In some embodiments, the third direction is set at a certain angle to the first direction. In this embodiment, the first direction, the second direction, and the third direction are perpendicular to each other, and the third direction can be a vertical direction.

[0065] For example, the clearance block 403 and the clearance groove 404 can be disposed on the first mating structure 405 and / or the second mating structure 406. Figure 4 A clearance block 403 is formed by setting a notch on the first sliding block 4051, that is, the first sliding block 4051 and the clearance block 403 are arranged along the first direction and are spaced apart. Figure 5 By setting a notch on the groove wall of the first sliding groove 4052 away from the left side wall 1011, the clearance groove 404 is formed on the first sliding groove 4052.

[0066] For example, when the receptive block 403 moves along the second direction toward the left side wall 1011 (or the first sliding groove 4052) and extends into the first sliding groove 4052 through the receptive groove 404, a sliding engagement is achieved between the first sliding block 4051 and the first sliding groove 4052, thereby achieving a sliding engagement between the mounting base 401 and the fixed bracket 402. When the receptive block 403 moves along the second direction away from the left side wall 1011 (or the first sliding groove 4052) and extends out of the first sliding groove 4052 through the receptive groove 404, the sliding engagement between the first sliding block 4051 and the first sliding groove 4052 is disengaged, thereby disengaging the sliding engagement between the mounting base 401 and the fixed bracket 402. Thus, the mounting base 401 and the fixed bracket 402 can be detached in the second direction.

[0067] For example, the fixed bracket 402 (i.e., the first sliding groove 4052) is provided with a plurality of clearance grooves 404, which are arranged along the first direction and spaced apart. The clearance block 403 can pass through any one of the aforementioned clearance grooves 404, so that the mounting base 401 only needs to slide a short distance or move a multiple distance along the first direction to achieve mutual engagement or disengagement with the fixed bracket 402, which facilitates the assembly and disassembly of the mounting base and the fixed bracket 402.

[0068] In some embodiments, the fixing device 40 further includes an adjusting column 409 that connects to the mounting base 401 and abuts against the inner liner 101. In this embodiment, the adjusting column 409 and the mounting base 401 can be movable in a third direction, such as an interference fit, to adjust the gap between the mounting base 401 and the drawer 20 (i.e., the clearance notch 201). For example, when the bottom wall 1012 of the inner liner 101 deforms due to foaming, adjusting the adjusting column 409 ensures that the adjusting column 409 abuts against the bottom wall 1012, thus guaranteeing the assembly accuracy between the mounting base 401 and the drawer 20 (i.e., the clearance notch 201). Simultaneously, it avoids excessive compression of the two mating structures (405, 406).

[0069] In some embodiments, the adjusting column 409 is located on the side of the mounting base 401 opposite to the fixed bracket 402 along the second direction. In this embodiment, the mounting base 401 is supported on one side (e.g., the left side) along the second direction by slidingly engaging with the fixed bracket 402 through two mating structures (405, 406), while the opposite side (e.g., the right side) along the second direction is supported by the adjusting column 409 abutting against the inner liner (e.g., the bottom wall 1012). This avoids the mounting base 401 from tilting relative to the second direction (e.g., the horizontal plane) and ensures the assembly accuracy between the mounting base 401 and the drawer 20 (i.e., the clearance notch 201).

[0070] For example, refer to Figure 7 As shown, the adjusting column 409 has a movable part 4091 and a latch 4092 connecting the movable part 4091. The mounting base 401 has a movable hole 4011 that matches the movable part 4091 and a slot 4012 that mates with the latch 4092. After the latch 4092 extends into the slot 4012 at the bottom of the mounting base 401 in a third direction, it can prevent the adjusting column 409 from disengaging from the mounting base 401. By utilizing the interference fit between the movable part 4091 and the movable hole 4011, the adjusting column 409 and the mounting base 401 can be adjusted in a third direction.

[0071] In some embodiments, the water supply system includes a kettle 302 connected to a filter 301. In this embodiment, the kettle 302 is connected to the outlet of the filter 301 to store the liquid filtered by the filter 301 for user use. The kettle 302 is placed inside the cooling chamber 102 to exchange heat with the interior of the cooling chamber 102 to obtain cold drinking water. The kettle 302 is configured as a coil kettle to improve the heat exchange efficiency between the kettle 302 and the cooling chamber 102.

[0072] In some embodiments, the mounting base 401 has a first cavity 4013 for accommodating the filter 301 and a second cavity 4014 for accommodating the kettle 302. In this embodiment, the mounting base 401 can accommodate the filter 301 and the kettle 302, thereby integrating the kettle 302 and the filter 301 and installing them in the refrigeration chamber 102. The kettle 302 obtains cooling energy by exchanging heat with the refrigeration chamber 102, thereby producing cold drinking water.

[0073] In some embodiments, the first cavity 4013 is located above the second cavity 4014. In this embodiment, the first cavity 4013 and the second cavity 4014 are separated from each other to avoid mutual interference; for example, liquid in the first cavity 4013 cannot flow downward into the second cavity 4014. The mounting base 401 can be disposed on the bottom wall 1012 of the inner liner 101, and the filter 301 is located above the kettle 302. That is, the filter 301 is located at the top, making it easy for the user to replace the filter element. The mounting base 401 or at least part of the second cavity 4014 is located in the cooling chamber 102, and the kettle 302 is located at the bottom, which facilitates heat exchange between the kettle 302 and the descending cold air in the cooling chamber 102.

[0074] In some embodiments, the refrigerator further includes an RFID tag 50. In this embodiment, considering that the filter needs to be replaced regularly and leakage is likely to occur at the interface after replacement, the RFID tag 50 is provided to detect water leakage in the filter 301.

[0075] For example, the radio frequency identification device 50 adopts wireless radio frequency identification technology, namely radio frequency identification (RFID), which is a type of automatic identification technology. It conducts non-contact two-way data communication through wireless radio frequency and uses wireless radio frequency to read and write recording media (such as electronic tags or RFID cards) to achieve the purpose of identifying targets and exchanging data.

[0076] Therefore, the RFID device 50 can be used to detect whether the filter 301 is leaking, and issue a leak warning. Alternatively, the RFID device 50 can be used to detect whether the filter element is original, and perform filter element identification, for example, by reading the electronic tag on the filter element to confirm whether it is original.

[0077] In some embodiments, the RFID tag 50 is located within the second cavity 4014. In this embodiment, the RFID tag 50 is located within the second cavity 4014, which prevents the user from touching the RFID tag 50 when the user replaces the filter cartridge in the first cavity 4013, and also prevents the liquid from affecting the RFID tag 50 in case of leakage.

[0078] In some embodiments, the RFID tag 50 is located between the filter 301 and the kettle 302. In this embodiment, the RFID tag 50 is located between the filter 301 and the kettle 304, making the RFID tag 50 closer to the filter 301, which is beneficial for leak detection and filter cartridge identification. For example, the filter 301, the RFID tag 50, and the kettle 304 are arranged vertically from top to bottom.

[0079] For example, the refrigerator also includes a connector 60 for connecting the inner liner 101 (e.g., the left side wall 1011), and the connector 60 is electrically connected to the radio frequency identification (RFID) device 50. The power line and / or signal line of the RFID device 50 are connected to the connector 60, and the external wiring between the connector 60 and the power supply and / or refrigerator control board is embedded in the insulation cavity 105.

[0080] In some embodiments, the mounting base 401 has a water collection tank 4017 communicating with the first cavity 4013. In this embodiment, the water collection tank 4017 is located below the filter 301 (or at the bottom of the first cavity 4013), so that leakage formed in the first cavity 4013 will accumulate in the water collection tank 4017. The radio frequency identification device 50 detects leakage by detecting the water collection tank 4017 at the bottom of the filter 301.

[0081] For example, by placing a test strip (i.e., a recording medium) in the water collection tank 4017, the test strip absorbs liquid and is sensed by the radio frequency identification device 50, thereby issuing a water leakage warning.

[0082] In some embodiments, the RFID tag 50 is located below the water collection tank 4017. In this embodiment, the RFID tag 50 is located below the water collection tank 4017 (or the filter 301) (e.g., directly below), thus being closer to the bottom of the filter 301 and the water collection tank 4017, which is beneficial for contactless wireless identification.

[0083] In some embodiments, the RFID tag 50 is connected to the mounting base 401. In this embodiment, the RFID tag 50 is integrated into the mounting base 401 for easy installation and subsequent maintenance. For example, the RFID tag 50 can be connected to the mounting base 401 (i.e., the base) via a snap-fit ​​connection.

[0084] In some embodiments, the refrigerator includes a cabinet 10 forming a compressor compartment 103 and a door pivotally connected to the cabinet 10, wherein the refrigeration compartment 102 is formed in the cabinet 10 or the door. In this embodiment, the refrigeration compartment 102 is formed in the cabinet 10 or the door, that is, the inner liner 101 may be disposed on the cabinet 10 or the door.

[0085] For example, the refrigeration chamber 102 is formed inside the housing 10, that is, the outer shell 104 and the inner liner 101 are disposed on the housing 10, and the compressor chamber 103 is formed directly from the outer shell 104 of the housing 10.

[0086] Of course, in other embodiments, the refrigeration chamber 102 can also be formed inside the door, in which case the outer shell 103 and the inner liner 101 are disposed on the door, and the compressor chamber 103 can be formed separately from the box.

[0087] In some embodiments, the water supply system further includes a kettle 302 located in the refrigeration compartment 102 and a first valve connected to the kettle 302. In this embodiment, the first valve is connected to the outlet of the kettle 302, thereby delivering water from the kettle 302 according to the user's water demand. For example, the first valve is configured as a one-in-two-out solenoid valve, thereby delivering water from the kettle 302 to the distributor and the ice maker respectively.

[0088] In some embodiments, the first valve is located inside the compressor chamber 103. In this embodiment, since the kettle 302 is located inside the refrigeration chamber 102 and the first valve is located inside the compressor chamber 103, and both the refrigeration chamber 102 and the compressor chamber 103 are located in the housing 10, the length of the water path (e.g., the second water pipe) between the kettle 302 and the first valve is shortened, reducing the loss of cooling capacity during the cooling water delivery process.

[0089] Furthermore, the first valve's location within the compressor compartment 103 saves internal space in the refrigeration compartment 102. It is also more suitable for modular refrigerators, where the refrigerator and freezer compartments are movable, independently operating units, such as built-in refrigerators. In this case, the two outlets of the first valve can be connected to any compartment (e.g., refrigerator or freezer), increasing flexibility.

[0090] For example, the water supply system also includes a second valve connected to the first water pipe and a second water pipe connecting the kettle 302 and the first valve. The second valve is located in the compressor compartment 103, which also saves internal space in the refrigeration compartment 102 and is closer to the external water source, facilitating connection between the second valve and the external water source. The second water pipe passes through a protective pipe 303, which protects multiple water pipes. Furthermore, the foaming material in the insulation cavity 105 insulates the second water pipe, preventing condensation from forming on it.

[0091] Similarly, since the filter 301 is located in the refrigeration chamber 102 and the second valve is located in the compressor chamber 103, and both the refrigeration chamber 102 and the compressor chamber 103 are located in the housing 10, the length of the water path (e.g., the first water pipe) between the filter 301 and the second valve is shortened.

[0092] For example, the mounting base 401 can be located at the bottom of the door of the refrigeration room 102. The mounting base 401 and the protective pipe 303 are arranged along the first direction to prevent the water pipes (e.g., the first water pipe and the second water pipe) inside the protective pipe 303 from bending. Furthermore, when the mounting base 401 slides in cooperation with the fixed bracket 402 along the first direction, it facilitates the passage of water pipes (e.g., the first water pipe and the second water pipe) through the protective pipe 303, which is convenient for the assembly of the water supply system.

[0093] In some embodiments, in conjunction with reference Figure 8 As shown, the mounting base 401 includes a base 4015 that mates with the filter 301 and a limiting cover 4016 that connects to the base 4015. In this embodiment, the filter 301 is detachably connected by the interconnected base 4015 and limiting cover 4016, which facilitates the installation and removal of the filter 301.

[0094] In some embodiments, the limiting cover 4016 engages with the base 4015 along a third direction. In this embodiment, after the limiting cover 4016 engages with the base 4015, it can prevent the filter 301 from separating from the mounting base 401, thereby fixing the filter 301.

[0095] In addition, by setting a snap-fit ​​groove 4018 on the base 4015, a snap-fit ​​connection with the limiting cover 4016 can be achieved. The snap-fit ​​groove 4018 is opposite to the connector 60, that is, the snap-fit ​​groove 4018 is located on the left side of the base 4015. Thus, the circuit of the radio frequency identification device 50 can be connected to the connector 60 through the snap-fit ​​groove 4018, which facilitates the installation and removal of the radio frequency identification device 50.

[0096] For example, the base 4015 has a mounting groove 40151 that matches the shape of the filter 301 and a support post 40152 disposed within the mounting groove 40151. After the filter 301 is placed in the mounting groove 40151, the offset of the filter 301 in the left-right direction is at least limited.

[0097] For example, the filter 301 has a mounting portion 3011, a filter element 3012 detachably connected to the mounting portion 3011, and an inlet 3013 and an outlet 3014 connecting the mounting portion 3011. The limiting cover 4016 has a limiting post 40161 corresponding to the support post 40152. After the limiting cover 4016 is engaged with the base 4015 along the second direction, a limiting space 4019 is formed between the support post 40152 and the limiting post 40161. The inlet 3013 and / or the outlet 3014 are located within the corresponding limiting space 4019, thereby limiting the vertical and horizontal displacement between the filter 301 and the mounting base 401.

[0098] For example, the filter 301 has a first axis L1 (e.g., parallel to the left-right direction) that is collinear with the centerline of the inlet 3013 and / or the outlet 3014, and a second axis L2 that is collinear with the centerline of the filter element 3012. The inlet 3013 and / or the outlet 3014 are located within corresponding limiting spaces 4019, which can restrict the rotation of the mounting portion 3011 relative to the mounting base 401 along the second axis L2. Thus, when rotating about the second axis L2 to install and remove the filter element 3012, loosening caused by rotation of the mounting portion 3011 along the second axis L2 is prevented.

[0099] For example, the inlet 3013 and / or outlet 3014 are located within the limiting space 4019, allowing the mounting part 3011 to rotate a certain angle along the first axis L1. This facilitates the user to tilt the filter element 3012 upwards at a certain angle, thereby smoothly rotating it for replacement. Tilting the filter element upwards at a certain angle increases the contact area between the user's palm and the filter 301, making it easier to grip and twist.

[0100] For example, the mounting base 401 has a front cover 410 and an upper cover 411. The front cover 410 is opened separately to facilitate filter replacement, while the upper cover 411 can be used to cover the limiting cover 40161.

[0101] In some embodiments, in conjunction with reference Figure 9 As shown, the inner liner 101 has a clearance step 1013 protruding into the refrigeration compartment 102. In this embodiment, the clearance step 1013 is located on the front side of the compressor compartment 103 and matches the shape of the compressor compartment 103 to avoid components such as the compressor inside the compressor compartment 103.

[0102] In some embodiments, at least a portion of the fixing device 40 is located in front of the clearance step 1013. In this embodiment, the clearance step 1013 is located at the bottom of the inner liner 101 and at the rear of the inner liner 101. By placing at least a portion of the fixing device 40 in front of the clearance step 1013, the internal space of the refrigeration chamber 102, i.e., the space in front of the clearance step 1013, can be fully utilized.

[0103] Furthermore, the space in front of the step 1013 is located at the bottom of the inner liner 101, which is a space that is not frequently used by users. The filter 301 is also a component that is not frequently replaced. Therefore, the space is used to place the fixing device 40, making more reasonable use of the space in the refrigeration compartment 102.

[0104] For example, such as Figure 9The mounting base 401 is positioned on the front side of the clearance step 1013. Since the fixing bracket 402 is attached to the inner liner 101 after being connected to it, even if the fixing bracket 402 is higher than the clearance step 1013, the space occupied by it in the refrigeration compartment 102 is relatively small.

[0105] For example, the step 1013 allows the cooling chamber 102 to form a first space 1021 located on the lower side and a second space 1022 located on the upper side of the first space 1021. In this embodiment, as... Figure 9 The dashed line L3 is a horizontal line that is flush with the upper surface of the yielding step 1013. The first space 1021 is located below the dashed line L3 (i.e., the upper surface of the yielding step 1013), and the second space 1022 is located above the dashed line L3 (the upper surface of the yielding step 1013).

[0106] For example, the front-to-back depth of the first space 1021 is less than the front-to-back depth of the second space 1022. In this embodiment, the clearance step 1013 is located at the bottom of the inner liner 101 and at the rear of the first space 1021, thereby occupying a portion of the space in the refrigeration chamber 102, resulting in a smaller front-to-back depth of the first space 1021.

[0107] For example, at least a portion of the fixing device 40 is located within the first space 1021. In this embodiment, the fixing device 40 (e.g., mounting base 401) is located within the first space 1021, which can effectively utilize the space in front of the clearance step 1013, and the first space 1021 is a space that is not frequently used by users, thereby making more rational use of the space in the refrigeration room 102.

[0108] For example, the mounting base 401 is located within the first space 1021, that is, the filter 301 and the kettle 302 are located within the first space 1021.
