Description

Technical Field

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

[0002] Cold brew coffee is a coffee beverage made by steeping coffee grounds in cold water for a longer period of time. Unlike traditional hot water brewing methods, cold brew coffee typically requires a longer steeping time. Because it uses cold water, cold brew coffee has lower acidity and a smoother texture.

[0003] In related technologies, extraction devices are used to improve the extraction efficiency of coffee from cold water. In a cold brew device, the coffee grounds container is located in an inner cup, which is placed inside an outer cup. A circulation pump draws water from the outer cup and injects it into the inner cup, which then flows through the coffee grounds container. This causes the water to circulate between the outer cup, the inner cup, and the coffee grounds container, thereby accelerating the contact rate between the water and the coffee grounds and improving the extraction efficiency of coffee from water.

[0004] However, after a period of use, coffee liquid tends to accumulate inside the circulation pump and on the inner walls of the pipes connected to the circulation pump. It is difficult for the extraction device to clean the inside of the circulation pump and the pipes connected to the circulation pump. If the coffee liquid is not cleaned for a long time, it can easily clog the pipes and breed bacteria and mold. Utility Model Content

[0005] This application provides a refrigerator that can solve the technical problem that related extraction devices have difficulty cleaning the inside of the circulation pump and the pipeline connected to the circulation pump.

[0006] This application provides a refrigerator, including:

[0007] The container is designed with a storage compartment.

[0008] A door for opening or closing the storage room; the door includes a rear wall that faces the storage room when the door is closed.

[0009] An extraction device, located on the rear wall of the door, includes:

[0010] The outer cup has a liquid storage cavity and a cup mouth;

[0011] The cup lid fits onto the mouth of the cup. The cup lid has a first flow channel and a second flow channel. The first flow channel is connected to the liquid storage chamber.

[0012] The filter element is located inside the liquid storage chamber and is disposed at the bottom of the cup lid. The filter element has a powder compartment, which is connected to the liquid storage chamber and the second flow channel respectively.

[0013] A fluid control mechanism is installed on the door body. The fluid control mechanism includes:

[0014] A connector assembly for connecting to a cup lid, the connector assembly having a third flow channel and a fourth flow channel, wherein when the connector assembly is connected to the cup lid, the third flow channel is connected to the first flow channel and the fourth flow channel is connected to the second flow channel;

[0015] A liquid extraction device has an inlet and an outlet, the inlet being connected to a third flow channel and the outlet being connected to a fourth flow channel;

[0016] The inlet valve assembly has an inlet, a first outlet, and a second outlet; the inlet is used to connect to a water source, the first outlet is connected to a third flow channel, and the second outlet is connected to the liquid inlet.

[0017] In this embodiment of the refrigerator, when the water inlet valve assembly is open and the liquid extraction device is activated, the fluid control mechanism is in cleaning mode. Water enters the water inlet valve assembly through the inlet and flows out from the first and second outlets. Water flowing out from the first outlet flows through the third channel to the first channel to rinse the third and first channels, reducing the amount of coffee liquid adhering to their inner walls. Water flowing out from the second outlet flows through the liquid inlet to the liquid extraction device and then flows from the liquid outlet to the fourth and second channels, cleaning the inside of the liquid extraction device, the pipes connected to the liquid extraction device, the fourth channel, and the second channel, reducing the amount of coffee liquid adhering to their inner walls.

[0018] In some embodiments of this application, the inlet valve assembly includes:

[0019] The valve body has an inlet and a main outlet. When the valve body is in the open state, the main outlet is connected to the inlet.

[0020] The diverter has an inlet, a first outlet, and a second outlet, with the inlet connected to the main outlet.

[0021] With this configuration, the inlet is connected to the main outlet. When the valve body is in the open state, the water source flows from the inlet to the main outlet and the inlet, and then flows to the first outlet and the second outlet respectively. The diverter divides the water source so that a portion of the water flows out from the first outlet and the other portion flows out from the second outlet.

[0022] In some embodiments of this application, the connector assembly includes:

[0023] The outer shell is located on the rear wall of the door. The outer shell has a receiving cavity, and the liquid pumping device and the water inlet valve assembly are respectively located in the receiving cavity.

[0024] The first flow guide is inserted into the bottom of the outer casing, and the first flow guide forms a third flow channel;

[0025] The second flow guide is installed at the bottom of the outer casing, and the second flow guide forms a fourth flow channel.

[0026] With this configuration, when the connector assembly is connected to the cup lid, the first and second flow guides are respectively connected to the cup lid, and the third flow channel is connected to the first flow channel, and the fourth flow channel is connected to the second flow channel.

[0027] In some embodiments of this application, the bottom end of the first guide member is located below the outer casing;

[0028] The connector assembly also includes a first seal located below the housing and surrounding the bottom periphery of the first guide member;

[0029] The cup lid includes:

[0030] The lid body fits into the mouth of the cup, and the lid body has a first flow channel and a second flow channel;

[0031] The second seal is located on the top of the lid body. The second seal has a connecting channel that communicates with the first channel. When the connector assembly is connected to the cup lid, the second seal and the first seal are sealed together, and the connecting channel communicates with the third channel.

[0032] With this configuration, when the connector assembly is connected to the cup lid, the second seal engages with the first seal to seal between the first guide and the first drain, reducing the possibility of liquid flowing from the gap between the first guide and the first drain to the outside of the first drain.

[0033] In some embodiments of this application, the first seal has a sealing cavity, a portion of the first guide is housed in the sealing cavity, and the side of the first seal away from the rear wall of the door has a passage opening that communicates with the sealing cavity and is used for the second seal to pass through.

[0034] When the connector assembly is connected to the cup lid, at least a portion of the second seal is accommodated within the sealing cavity, and the second seal blocks the passage.

[0035] With this configuration, an opening is constructed on the side of the first seal that faces away from the rear wall of the door. The extraction device only needs to be moved along the thickness direction of the door to achieve sealing or release of the first and second seals. There is no need to move the extraction device along the height direction of the door. This can seal the first guide and the first drain, and also reduce the difficulty of taking the extraction device out of the door.

[0036] In some embodiments of this application, the cup lid includes:

[0037] The connector is located inside the liquid storage chamber and is positioned on top of the outer cup; the filter component is connected to the connector.

[0038] The cover body fits onto the top of the connector, and the cover body has a first flow channel and a second flow channel.

[0039] With this design, the cup lid formed by the connector and the lid body can be cleaned separately when cleaning the cup lid. Compared with a one-piece molded cup lid, this reduces the cleaning dead corners inside the cup lid, reduces the difficulty of cleaning the cup lid, and can improve the cleaning effect of the cup lid.

[0040] In some embodiments of this application, the connector is configured with mounting holes, the filter element passes through the mounting holes, and the filter element overlaps the side of the connector facing the cover body.

[0041] With this configuration, the filter component overlaps on the side of the connector facing the cover body, simplifying the assembly structure of the filter component and the connector, and making it easier to install and disassemble the filter component and the connector.

[0042] In some embodiments of this application, the filtering component includes:

[0043] The powder storage component is connected to the bottom of the cup lid and has a powder hopper;

[0044] Liquid guiding components, including:

[0045] The connecting part is attached to the bottom of the powder storage component;

[0046] The liquid guiding section is located inside the powder hopper. The top end of the liquid guiding section is connected to the cup lid, and the bottom end of the liquid guiding section is connected to the connecting part. The liquid guiding section forms a liquid guiding channel, which is connected to the first flow channel and the liquid storage chamber respectively.

[0047] With this configuration, when the fluid control mechanism is in cleaning mode, the water flowing down from the first flow channel can be guided through the liquid guide channel to flow out from the bottom of the powder storage assembly. This prevents the water flowing down from the first flow channel from directly impacting the coffee particles in the powder compartment. Instead, the water flows through the liquid guide channel into the liquid storage chamber first, and then meanders from the liquid storage chamber into the powder compartment to contact the coffee particles. This reduces the possibility that the coffee particles will expand rapidly due to direct impact from the water and overflow from the top of the powder storage assembly.

[0048] In some embodiments of this application, the powder storage component includes:

[0049] The powder filling component is connected to the cup lid. The powder filling component has a powder filling cavity and a powder filling port is formed at the top of the powder filling port.

[0050] The powder storage component has a powder hopper, which is connected to the bottom of the powder injection component and is connected to the powder injection cavity; the side wall of the powder storage component has mesh holes, which are connected to the powder hopper and the liquid storage cavity respectively.

[0051] With this design, coffee granules are added to the injection chamber through the injection port, and the granules move downwards into the powder container. The mesh prevents coffee granules from entering the liquid storage chamber, allowing only liquid to pass through. The brewing liquid in the liquid storage chamber enters the powder container through the mesh, comes into contact with the coffee granules, and dissolves and extracts soluble flavor compounds and caffeine.

[0052] In some embodiments of this application, the bottom end of the second flow channel is located inside the powder injection cavity or above the powder injection cavity.

[0053] With this design, the liquid flowing out from the bottom of the second flow channel can flow directly into the powder injection chamber, and then flow downwards from the powder injection chamber to the top of the powder container. The liquid flows downwards from the top of the powder container, allowing it to flow from top to bottom through the entire powder container. This ensures that the liquid comes into contact with coffee particles at different heights within the powder container, thus improving the extraction efficiency of the coffee.

[0119] To make the objectives and implementation methods of this application clearer, the exemplary implementation methods of this application will be clearly and completely described below with reference to the accompanying drawings of the exemplary embodiments of this application. Obviously, the exemplary embodiments described are only some embodiments of this application, and not all embodiments.

[0120] It should be noted that the brief descriptions of terms in this application are only for the convenience of understanding the embodiments described below, and are not intended to limit the embodiments of this application. Unless otherwise stated, these terms should be understood in their ordinary and common meaning.

[0121] The terms "first," "second," "third," etc., used in the specification, claims, and accompanying drawings of this application are used to distinguish similar or related objects or entities, and do not necessarily imply a specific order or sequence, unless otherwise specified. It should be understood that such terms are interchangeable where appropriate.

[0122] The terms “comprising” and “having”, and any variations thereof, are intended to cover but not exclude inclusion, for example, a product or device that includes a range of components is not necessarily limited to all of the components that are clearly listed, but may include other components that are not clearly listed or that are inherent to such product or device.

[0123] Regarding the extraction devices in related technologies, there is a technical problem that it is difficult to clean the inside of the circulating pump and the pipeline connected to the circulating pump. This application provides a refrigerator with a water inlet valve assembly connected to a liquid extraction device. The water inlet of the water inlet valve assembly is used to connect to a water source. The water inlet valve assembly has a first water outlet and a second water outlet. The first water outlet is connected to a third flow channel, and the second water outlet is connected to the liquid inlet of the liquid extraction device. When it is necessary to clean the inside of the liquid extraction device and the pipeline connected to the liquid extraction device, the water inlet valve assembly is opened, and the liquid extraction device is started, allowing water to flow in through the water inlet. After the water inlet valve assembly, the water flowing out from the first outlet flows through the third flow channel to the first flow channel to flush the third and first flow channels, thereby reducing the coffee liquid adhering to the inner walls of the third and first flow channels. The water flowing out from the second outlet flows through the liquid inlet to the inside of the pumping device, and then flows from the liquid outlet to the fourth and second flow channels in sequence, in order to clean the inside of the pumping device, the pipes connected to the pumping device, the fourth flow channel, and the second flow channel, thereby reducing the coffee liquid adhering to the inner walls of the pumping device, the pipes connected to the pumping device, the fourth flow channel, and the second flow channel.

[0124] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0125] It should be noted that, in the embodiments of this application, "front side" refers to the side of the refrigerator facing the user when it is in normal use. "Rear side" refers to the side opposite to the front side, that is, the side of the refrigerator facing away from the user when it is in normal use.

[0126] refer to Figure 1 The refrigerator provided in this application embodiment may include a cabinet 10 having a storage compartment 111, a door 20 connected to the cabinet 10 to open and close the storage compartment 111, and a refrigeration device for supplying cold air to the storage compartment 111.

[0127] A refrigeration unit may be installed inside the enclosure 10. The refrigeration unit can be any refrigeration unit in the related art. The refrigeration unit is used to provide cold air to the storage compartment 111 to reduce the temperature inside the storage compartment 111.

[0128] refer to Figure 1The box body 10 may include a box liner 110, and a storage compartment 111 may be formed inside the box liner 110. A retrieval opening 112 may be formed on the front side of the storage compartment 111, through which the user can take items from the storage compartment 111 or put items into the storage compartment 111.

[0129] It is understood that the number of storage compartments 111 can be one, two, or more than three. Storage compartments 111 can be configured as refrigerators, freezers, or variable temperature compartments with internal temperature variations.

[0130] refer to Figure 1 The housing 10 may also include a housing shell 20. The housing shell 20 is attached to the outside of the housing liner 110 to form the appearance of the housing 10.

[0131] refer to Figure 1 The enclosure 10 may include a front wall 101, which may be located on the front side of the enclosure 10. The front wall 101 may be the front wall of the enclosure shell 20, or it may be formed by joining the front wall of the enclosure shell 20 and the front wall of the inner liner 110.

[0132] In some possible implementations of the embodiments of this application, the door 20 can be rotatably connected to the box 10 to open and close the access port 112 of the storage room 111.

[0133] The opening and closing states of the door 20 can include an open state and a closed state.

[0134] When door 20 is in the open state (refer to) Figure 1 When the door 20 opens the access port 112, the user can take items from or put items into the storage room 111 through the access port 112.

[0135] When the door 20 is closed, the door 20 closes the access port 112 to reduce the leakage of cold air from the access port 112 in the storage compartment 111, thereby improving the cooling effect of the refrigerator on the items in the storage compartment 111.

[0136] Each storage room 111 may be equipped with at least one door 20.

[0137] Understandably, reference Figure 1 Each storage room 111 may also be equipped with two double doors 20, which will not be described in detail in this embodiment.

[0138] refer to Figure 1 The door body 20 may include a door frame 210. The door frame 210 can be rotatably connected to the housing 10. The door frame 210 has high structural strength, and the rotatable connection between the door frame 210 and the housing 10 can improve the reliability of the connection between the door frame 210 and the housing 10.

[0139] refer to Figure 1 The door body 20 may further include an inner door liner 220 and a door panel 230. The door panel 230 and the inner door liner 220 may be respectively connected to opposite sides of the door frame 210 along its own thickness direction. When the door body 20 is closed, the inner door liner 220 is closer to the storage compartment 111 than the door panel 230. When the door body 20 is closed, the thickness direction of the door frame 210 is substantially consistent with the depth direction of the cabinet 10. The door panel 230, the inner door liner 220, and the door frame 210 form the appearance of the door body 20.

[0140] refer to Figure 3 Along the thickness direction of the door body 20, the door liner 220 and the door panel 230 can be spaced apart, forming a heat insulation cavity by the door panel 230, the door liner 220, and the door frame 210. The heat insulation cavity can be filled with heat insulation material, such as foaming agent, which can reduce the heat exchange between the storage compartment 111 inside the refrigerator and the outside, thus achieving a heat preservation effect.

[0141] refer to Figure 1 The door 20 may include a rear wall 221. When the door 20 is closed, the rear wall 221 may be located on the rear side of the door 20. It should be noted that the rear wall 221 is not a perfectly flat surface; a door seal may be provided on the rear wall 221 to improve sealing, and storage space, such as a storage box or an ice maker, may also be provided. It can be understood that when the door 20 is closed, a portion of the rear wall 221 corresponds to the access opening 112, and another portion of the rear wall 221 corresponds to the front wall 101 of the cabinet. At least part of the rear wall 221 around its perimeter cooperates with the front wall of the cabinet 10 to form a relatively sealed space in the storage compartment 111.

[0142] The rear wall 221 of the door can be the rear wall of the inner door liner 220, or it can include the rear wall of the door frame 210 and the rear wall of the inner door liner 220.

[0143] The door body 20 may also include a front wall. The front wall and the rear wall 221 are disposed opposite each other along the thickness direction of the door body 20. When the door body 20 is in the closed state, the front wall may be located on the front side of the door body 20. The front wall may be the front wall of the door panel 230.

[0144] In some possible implementations of the embodiments of this application, reference is made to Figure 1 The door body 20 may also include a door shelf 240. The door shelf 240 may be located on one side of the rear wall 221 of the door body 20. The door shelf 240 can be used to place items to improve the space utilization of the storage room 111 and to facilitate the user's access to items. The door shelf 240 may be installed in the inner door liner 220.

[0145] refer to Figure 2The refrigerator may also include an extraction device 30 for extracting beverages such as coffee. The extraction device 30 may be installed directly or indirectly on the rear wall 221 of the door.

[0146] In some implementations, the extraction device 30 can be detachably mounted on the rear wall 221 of the door. For example, the rear wall 221 of the door can be provided with a hook portion, and the extraction device 30 can be provided with a hanging channel. The hook portion is hung in the hanging channel so that the extraction device 30 can be directly hung on the rear wall 221 of the door.

[0147] In some other implementations, the extraction device 30 may be selectively placed within the door shelf 240. That is, the extraction device 30 may be placed within the door shelf 240 or removed from the door shelf 240 so that the extraction device 30 is indirectly disposed on the rear wall 221 of the door via the door shelf 240.

[0148] In other implementation methods, refer to Figure 2 and Figure 3 The door body 20 may also include a placement platform 250, which is connected to the rear wall 221 of the door, and the retrieval device can be placed on the placement platform 250.

[0149] refer to Figure 3 The top of the placement platform 250 may also be constructed with a placement groove 251, in which the extraction device 30 may be selectively placed. That is, the extraction device 30 may be placed in the placement groove 251 or removed from the placement groove 251, so that the extraction device 30 may be indirectly set on the rear wall 221 of the door through the placement platform 250.

[0150] refer to Figure 4 and Figure 5 The extraction device 30 may include an outer cup 310. The outer cup 310 may be a cylindrical cup, a cuboid cup, or a cup of other shapes. A liquid storage cavity 3111 may be formed inside the outer cup 310. The liquid storage cavity 3111 may be used to hold the brewing liquid, which may be purified water, mineral water, etc., and the brewing liquid is used to brew beverages such as coffee.

[0151] refer to Figure 5 The top of the outer cup 310 may have a cup opening 3112, which is connected to the liquid storage chamber 3111. The brewing liquid can be added into the liquid storage chamber 3111 through the cup opening 3112.

[0152] refer to Figure 5 The top edge of the outer cup 310 may have a spout 3113, through which liquid in the liquid storage chamber 3111 can be poured out. The spout 3113 can guide the liquid flow, reducing or preventing liquid from dripping along the outer wall of the outer cup 310 after pouring, so as to keep the outer cup 310 clean.

[0153] refer to Figure 5 The outer cup 310 may include an outer cup body 311 and a handle 312. The outer cup body 311 is constructed with a liquid storage cavity 3111, a cup mouth 3112 and a cup spout 3113. The handle 312 may be provided on the outer side wall of the outer cup body 311, and the handle 312 can facilitate holding the outer cup 310.

[0154] refer to Figure 4 and Figure 5 The extraction device 30 may also include a lid 320. The lid 320 can be closed to cover the mouth 3112 to reduce the entry of dust and other particles into the liquid storage chamber 3111.

[0155] In some possible implementations of the embodiments of this application, reference is made to Figure 4 , Figure 5 and Figure 6 The cup lid 320 may include a connector 345, which may be located within the liquid storage cavity 3111 and disposed on the top of the outer cup 310. The top edge of the connector 345 may overlap the top edge of the outer cup 310.

[0156] refer to Figure 5 The connector 345 may be configured with a liquid outlet chamber 3452, which is connected to the liquid storage chamber 3111. The connector 345 may be configured with a liquid outlet nozzle 3451, which is connected to the liquid outlet chamber 3452, and the liquid outlet nozzle 3451 may be fitted to the spout 3113.

[0157] When the connector 345 is attached to the outer cup 310, the liquid in the liquid outlet chamber 3452 can be poured out from the liquid outlet chamber 3452 and the liquid outlet 3451.

[0158] In some possible implementations of the embodiments of this application, reference is made to Figure 4 , Figure 5 and Figure 6 The cup lid 320 may also include a lid body 341, which can be fitted onto the top of the connector 345. In an implementation where the connector 345 is configured with a dispensing nozzle 3451, the lid body 341 fits onto the top of the connector 345 other than the dispensing nozzle 3451, so that when the lid body 341 fits onto the top of the connector 345, the liquid in the storage chamber 3111 can be poured out from the dispensing nozzle 3451 without disassembling the lid body 341.

[0159] The cup lid 320, formed by the connector 345 and the lid body 341, allows for separate cleaning of both the connector 345 and the lid body 341 during cleaning. Compared to a one-piece molded cup lid 320, this reduces cleaning dead spots inside the cup lid 320, decreases the difficulty of cleaning the cup lid 320, and improves the cleaning effect of the cup lid 320.

[0160] refer to Figures 4-8 The extraction device 30 may also include a filter element 330. The filter element 330 has a powder container 3314, which can hold ground coffee particles of varying sizes to suit individual tastes. The filter element 330 is located within a liquid reservoir 3111 and is positioned at the bottom of the lid 320. The powder container 3314 can communicate with the liquid reservoir 3111.

[0161] The brewing liquid in the reservoir 3111 soaks the coffee particles in the powder container 3314 to extract the coffee beverage.

[0162] In some possible implementations of the embodiments of this application, reference is made to Figure 5 The filter component 330 may include a powder storage assembly 331, which may be connected to the bottom of the cup lid 320 and has a powder hopper 3314.

[0164] refer to Figure 5 and Figure 8 The powder storage assembly 331 may also include a powder storage component 3313, which has a powder container 3314 located below the powder filling chamber 3312. The powder container 3314 is connected to the powder filling chamber 3312 and coffee particles are added to the powder filling chamber 3312 through the powder filling port. The coffee particles move downward from the powder filling chamber 3312 into the powder container 3314.

[0165] The powder storage component 3313 is connected to the bottom of the powder injection component 3311.

[0166] In some embodiments, the powder storage component 3313 and the powder injection component 3311 can be threaded together to facilitate disassembly of the powder storage component 3313 and the powder injection component 3311, thereby facilitating cleaning of the powder storage component 3313 and the powder injection component 3311.

[0167] In other embodiments, the powder storage component 3313 and the powder injection component 3311 can be integrally formed to simplify the assembly process.

[0168] The sidewall of the powder storage component 3313 may have a mesh, which communicates with both the powder container 3314 and the liquid storage chamber 3111. The mesh prevents coffee particles in the powder container 3314 from entering the liquid storage chamber 3111, allowing only liquid to pass through. The brewing liquid in the liquid storage chamber 3111 enters the powder container 3314 through the mesh, and upon contact with the coffee particles in the powder container 3314, dissolves and extracts soluble flavor substances and caffeine from the coffee particles.

[0169] In the implementation of the cup lid 320, which includes a lid body 341 and a connector 345, the filter member 330 can be connected to the connector 345.

[0171] In the implementation of the filter component 330 including the powder injection component 3311, the powder injection component 3311 can be threadedly connected to the connector 345.

[0172] In other embodiments, reference is made to Figure 5 , Figure 6 and Figure 8 The connector 345 may be configured with a mounting hole 3453, and the filter element 330 may pass through the mounting hole 3453, with the filter element 330 overlapping the side of the connector 345 facing the cover body 341. This overlap of the filter element 330 with the side of the connector 345 facing the cover body 341 simplifies the assembly structure of the filter element 330 and the connector 345, facilitating the installation and removal of the filter element 330 and the connector 345.

[0173] refer to Figure 8 In the implementation of the filter component 330 including the powder injection component 3311, the powder injection component 3311 can be inserted into the mounting hole 3453, and the powder injection component 3311 overlaps the side of the connector 345 facing the cover body 341.

[0174] The refrigerator may also include a fluid control mechanism 40, which is disposed on the door 20.

[0175] refer to Figure 3 and Figure 9 The cup lid 320 may be constructed with a first flow channel 3421 and a second flow channel 3431. The first flow channel 3421 is connected to the liquid storage chamber 3111. The second flow channel 3431 may be directly connected to the powder hopper 3314; or it may be connected to the space above the powder hopper 3314 (e.g., the powder injection chamber 3312), thereby indirectly connecting to the powder hopper 3314.

[0176] refer to Figure 6In the implementation of the cup lid 320 including the lid body 341, the cup lid 320 may also include a first flow guide 342, which is disposed through the lid body 341 and forms a first flow channel 3421.

[0177] refer to Figure 6 The cup lid 320 may also include a second flow guide 343, which is disposed through the lid body 341 and forms a second flow channel 3431.

(Reference) Figure 9 When the connector assembly 410 is connected to the cup lid 320, the third flow channel 4121 is connected to the first flow channel 3421, and the fourth flow channel 4131 is connected to the second flow channel 3431.

[0179] refer to Figure 10 and Figure 11 The connector assembly 410 may include a housing 411, which may be disposed on the rear wall 221 of the door.

[0180] refer to Figure 11 The connector assembly 410 may also include a first flow guide 412, which is disposed at the bottom of the housing 411. The first flow guide 412 may be tubular and has a third flow channel 4121.

[0182] refer to Figure 9 and Figure 12 When the connector assembly 410 is connected to the cup lid 320, the first flow guide 412 and the second flow guide 413 are respectively connected to the cup lid 320. The first flow guide 412 is connected to the first flow guide 342, the second flow guide 413 is connected to the second flow guide 343, and the third flow channel 4121 is connected to the first flow channel 3421, and the fourth flow channel 4131 is connected to the second flow channel 3431.

[0183] refer to Figure 2 The fluid control mechanism 40 may also include a pumping device 420, and the housing 411 may be configured with a receiving cavity 4111, and the pumping device 420 may be disposed within the receiving cavity 4111.

[0184] The liquid pumping device 420 can be a water pump or other device that can pump liquid.

[0185] refer to Figure 13 and Figure 14 The liquid extraction device 420 may have an inlet 4221 and an outlet 4231. The liquid extraction device 420 has an open state and a closed state. When the liquid extraction device 420 is in the open state, liquid can enter the liquid extraction device 420 from the inlet 4221 and flow out from the outlet 4231. When the liquid extraction device 420 is in the open state, liquid at the inlet 4221 cannot flow to the outlet 4231.

[0186] The inlet 4221 is connected to the third flow channel 4121, and the outlet 4231 is connected to the fourth flow channel 4131.

[0187] refer to Figure 13 and Figure 14 The liquid extraction device 420 may include a liquid extraction element 421. The liquid extraction element 421 may be a water pump or other device capable of extracting liquid. The liquid extraction element 421 has a fluid inlet and a fluid outlet. When the liquid extraction element 421 is turned on, liquid can enter the liquid extraction element 421 from the fluid inlet and flow out from the fluid outlet.

[0188] refer to Figure 13 and Figure 14 The pumping device 420 may further include an inlet pipe 422, which can be connected between the pumping member 421 and the first guide member 412. One end of the inlet pipe 422 is connected to the fluid inlet of the pumping member 421, and the end of the inlet pipe 422 away from the pumping member 421 forms an inlet port 4221. The inlet port 4221 is connected to the third flow channel 4121, and the fluid inlet and the third flow channel 4121 are connected through the inlet pipe 422.

[0189] refer to Figure 13 and Figure 14 The liquid extraction device 420 may further include a liquid outlet pipe 423, which can be connected between the liquid extraction member 421 and the second flow guide member 413. One end of the liquid outlet pipe 423 is connected to the fluid outlet of the liquid extraction member 421, and the end of the liquid outlet pipe 423 facing away from the liquid extraction member 421 forms a liquid outlet 4231. The liquid outlet 4231 is connected to the fourth flow channel 4131, and the fluid outlet and the fourth flow channel 4131 are connected through the liquid outlet pipe 423.

[0190] refer to Figure 12 When the liquid extraction component 421 is opened, the liquid in the storage chamber 3111 flows sequentially from the first inlet component 342 through the first guide component 412, the inlet pipe 422, the extraction component 421, the outlet pipe 423, and the second guide component 413. The liquid flowing out from the second guide component 413 flows through the powder hopper 3314 and then flows back into the storage chamber 3111. (Reference) Figure 9In other words, the flow path of the liquid in the storage chamber 3111 (red indicator line) is as follows: storage chamber 3111 → first flow channel 3421 → third flow channel 4121 → inlet pipe 422 → pumping component 421 → outlet pipe 423 → fourth flow channel 4131 → second flow channel 3431 → powder filling chamber 3312 → powder container 3314 → storage chamber 3111, and so on, to increase the contact rate between the brewing liquid and the coffee particles in the powder container 3314, thereby improving the extraction efficiency of coffee.

[0191] refer to Figure 2 The fluid control mechanism 40 may also include an inlet valve assembly 430, which may be disposed within the accommodating cavity 4111.

[0192] refer to Figure 13 and Figure 14 The inlet valve assembly 430 may have an inlet 4311, a first outlet 4322, and a second outlet 4323. The inlet 4311 is used to connect to a water source.

[0193] The inlet valve assembly 430 can have an open state and a closed state.

[0194] When the inlet valve assembly 430 is in the open state, water can enter the inlet valve assembly 430 from the inlet port 4311 and flow out from the first outlet port 4322 and the second outlet port 4323 respectively.

[0195] When the inlet valve assembly 430 is closed, water cannot enter the inlet 4311, and no water flows out of the first outlet 4322 and the second outlet 4323.

[0196] In some possible implementations of this application, the door 20 may include a water tank for storing water. The inlet 4311 may be connected to the outlet of the water tank. When the inlet valve assembly 430 is open, the water in the tank can flow through the inlet 4311 to the first outlet 4322 and the second outlet 4323.

[0197] In some possible implementations of the embodiments of this application, the inlet 4311 of the inlet valve group 430 can be connected to a tap water pipeline. When the inlet valve group 430 is in the open state, the water source in the tap water pipeline can flow through the inlet 4311 to the first outlet 4322 and the second outlet 4323.

[0198] In some possible implementations of the embodiments of this application, reference is made to Figure 13 and Figure 14 The inlet valve assembly 430 may include a valve body 431, which may have an inlet 4311 and a main outlet 4312. When the valve body 431 is in the open state, the main outlet 4312 is connected to the inlet 4311.

[0199] refer to Figure 13 and Figure 14 The inlet valve assembly 430 may further include a diverter 432, which may have an inlet 4321, a first outlet 4322, and a second outlet 4323. The inlet 4321, the first outlet 4322, and the second outlet 4323 are respectively connected to the inner cavity of the diverter 432. The inlet 4321 is connected to the main outlet 4312. When the valve body 431 is in the open state, water flows from the inlet 4311 to the main outlet 4312 and the inlet 4321, and then flows to the first outlet 4322 and the second outlet 4323 respectively. The diverter 432 diverts the water so that a portion of the water flows out from the first outlet 4322 and the other portion flows out from the second outlet 4323.

[0200] refer to Figure 12 The diverter 432 can be connected to the valve body 431 and the first guide 412 respectively, and the first outlet 4322 is connected to the top of the third flow channel 4121.

[0201] refer to Figure 12 The diverter 432 can be connected to the valve body 431 and the inlet pipe 422 respectively, and the second outlet 4323 is connected to the inlet 4221. The inlet pipe 422 is connected to the third flow channel 4121 through the diverter 432.

[0202] The fluid control mechanism 40 can have a water injection mode, an extraction mode, and a cleaning mode.

[0203] refer to Figure 15 When the liquid extraction device 420 is in the closed state and the water inlet valve group 430 is in the open state, the fluid control mechanism 40 is in the water injection mode. Figure 15 The flow path of the greywater is indicated by blue lines. The water source flows from the inlet 4311 to the first outlet 4322, and then flows from the third channel 4121 through the first channel 3421 into the storage chamber 3111 to inject water into the storage chamber 3111.

[0204] Referring to 16, a liquid level detection device 50 can be installed on the door body 20. The liquid level detection device 50 can be a liquid level sensor or an infrared sensor, etc. When the extraction device 30 is installed on the door body 20, the liquid level detection device 50 can detect the liquid level height in the liquid storage chamber 3111.

[0205] The refrigerator may also include a control device, which may be electrically connected to the water inlet valve assembly 430 and the liquid level sensor respectively. The control device may close the water inlet valve assembly 430 when the liquid level in the liquid storage chamber 3111 reaches the set liquid level, so as to reduce the possibility that the liquid level in the liquid storage chamber 3111 exceeds the set liquid level.

[0206] refer to Figure 9 When the inlet valve group 430 is closed and the liquid extraction device 420 is open, the fluid control mechanism 40 is in extraction mode. The liquid in the storage chamber 3111 flows sequentially from the first inlet 342 through the first guide 412, the inlet pipe 422, the extraction 421, the outlet pipe 423, and the second guide 413. The liquid flowing out from the second guide 413 flows through the powder container 3314 and then flows back into the storage chamber 3111. In other words, the flow path of the liquid in the storage chamber 3111 is: storage chamber 3111 → first flow channel 3421 → third flow channel 4121 → inlet pipe 422 → extraction 421 → outlet pipe 423 → fourth flow channel 4131 → second flow channel 3431 → powder filling chamber 3312 → powder container 3314 → storage chamber 3111. This cycle is repeated to increase the contact rate between the brewing liquid and the coffee particles in the powder container 3314, thereby improving the extraction efficiency of coffee.

[0207] refer to Figure 17 When the inlet valve assembly 430 is in the open state and the liquid extraction device 420 is in the open state, the fluid control mechanism 40 is in the cleaning mode.

[0208] Figure 17 The flow path of the greywater is indicated by the green indicator line. The water source enters the interior of the inlet valve assembly 430 from the inlet 4311 and flows out from the first outlet 4322 and the second outlet 4323 respectively.

[0209] Water flowing out of the first outlet 4322 flows into the liquid storage chamber 3111 through the third channel 4121 and the first channel 3421 to rinse the third channel 4121 and the first channel 3421, thereby reducing the coffee liquid adhering to the inner walls of the third channel 4121 and the first channel 3421.

[0210] Water flowing out from the second outlet 4323 flows sequentially through the inlet 4221 to the inlet pipe 422, the inside of the extraction component 421, and the outlet pipe 423. It then flows sequentially from the outlet 4231 to the fourth flow channel 4131 and the second flow channel 3431 to clean the inlet pipe 422, the inside of the extraction component 421, the outlet pipe 423, the fourth flow channel 4131, and the second flow channel 3431, thereby reducing the amount of coffee liquid adhering to the inner walls of the inlet pipe 422, the inside of the extraction component 421, the outlet pipe 423, the fourth flow channel 4131, and the second flow channel 3431.

[0211] In some possible implementations of the embodiments of this application, the bottom end of the first guide member 412 may be located below the outer casing 411.

[0212] refer to Figure 11The connector assembly 410 may further include a first seal 414, which may be a rubber component or a silicone component, etc. The first seal 414 is located below the housing 411 and surrounds and is connected to the bottom outer periphery of the first guide member 412.

[0213] refer to Figure 4 In the embodiment where the cup lid 320 includes a lid body 341, the lid body may further include a second sealing element 344, which may be a rubber element or a silicone element, etc. The second sealing element 344 may be disposed on the top of the lid body 341, and the second sealing element 344 has a communicating flow channel 3441, which is connected to the first flow channel 3421.

[0214] refer to Figure 9 When the connector assembly 410 is connected to the cup lid 320, the connecting channel 3441 is connected to the third channel 4121, so that the third channel 4121 can be connected to the first channel 3421 through the connecting channel 3441. (Reference) Figure 12 When the connector assembly 410 is connected to the cup lid 320, the second seal 344 and the first seal 414 are sealed together to seal between the first guide 412 and the first drain 342, reducing the possibility of liquid flowing from the gap between the first guide 412 and the first drain 342 to the outside of the first drain 342.

[0215] In some possible implementations of the embodiments of this application, reference is made to Figure 11 The first seal 414 may form a sealing cavity 4141, and part of the first guide 412 is housed in the sealing cavity 4141. The side of the first seal 414 away from the rear wall 221 of the door may be constructed with a through port 4142, which communicates with the sealing cavity 4141 and is used for the second seal 344 to pass through.

[0216] When the connector assembly 410 is connected to the cup lid 320, at least a portion of the second seal 344 is accommodated in the sealing cavity 4141, and the second seal 344 blocks the passage 4142.

[0217] When it is necessary to remove the extraction device 30 from the door body 20, the outer cup 310 can be moved along the thickness direction Y of the door body 20 in a direction away from the rear wall 221 of the door. During this process, the second seal 344 moves away from the rear wall 221 of the door along with the outer cup 310 and is removed from the passage 4142.

[0218] When it is necessary to connect the extraction device 30 to the connector assembly 410, the outer cup 310 can be moved toward the rear wall 221 of the door along the thickness direction Y of the door body 20. During this process, the second seal 344 moves toward the rear wall 221 of the door along with the outer cup 310 and moves from the passage 4142 into the sealing cavity 4141. When the second seal 344 blocks the passage 4142, the first seal 414 and the second seal 344 achieve a sealing fit.

[0219] A passage 4142 is constructed on the side of the first seal 414 away from the rear wall 221 of the door. The first seal 414 and the second seal 344 can be sealed or unsealed simply by moving the extraction device 30 along the thickness direction Y of the door body 20. There is no need to move the extraction device 30 along the height direction Z of the door body 20. This can seal the first guide 412 and the first guide 342 and reduce the difficulty of taking the extraction device 30 out of the door body 20.

[0220] refer to Figure 5 In an implementation where the filter element 330 includes a powder storage assembly 331, the filter element 330 may further include a liquid guiding member 332. The liquid guiding member 332 may include a connecting portion 3321, which may be connected to the bottom of the powder storage assembly 331. Exemplarily, the connecting portion 3321 may be threadedly connected to the powder storage assembly 331 to facilitate disassembly of the connecting portion 3321 and the powder storage assembly 331, thereby facilitating cleaning of both.

[0221] The liquid guiding component 332 may further include a liquid guiding section 3322, which is located within the powder hopper 3314 and may be tubular. The top end of the liquid guiding section 3322 is connected to the cup lid 320, and the bottom end is connected to the connecting section 3321. The liquid guiding section 3322 forms a liquid guiding channel 3323, the top end of which may communicate with the first flow channel 3421, and the bottom end of which may communicate with the liquid storage chamber 3111. The liquid guiding channel 3323 is connected to both the first flow channel 3421 and the liquid storage chamber 3111.

[0222] refer to Figure 15 When the fluid control mechanism 40 is in the cleaning mode, the water flowing down from the first flow channel 3421 can be guided through the liquid guiding channel 3323 to flow out from the bottom of the powder storage component 331. This makes it less likely for the water flowing down from the first flow channel 3421 to directly impact the coffee particles in the powder container 3314. Instead, the water flows through the liquid guiding channel 3323 to the liquid storage chamber 3111 first, and then detours from the liquid storage chamber 3111 to the powder container 3314 to contact the coffee particles. This reduces the possibility that the coffee particles will expand rapidly due to direct impact from the water and overflow from the top of the powder container.

[0223] In some possible implementations of the embodiments of this application, reference is made to Figure 8 and Figure 9 The powder injection component 3311 can form a powder injection cavity 3312. The bottom end of the second flow channel 3431 can be located inside or above the powder injection cavity 3312, so that the liquid flowing out from the bottom end of the second flow channel 3431 can flow directly into the powder injection cavity 3312 and flow down from the powder injection cavity 3312 to the top of the powder container 3314. The liquid flows down from the top of the powder container 3314, and the liquid can flow from top to bottom through the entire powder container 3314, so that the liquid comes into contact with coffee particles at different heights in the powder container 3314, thereby improving the extraction efficiency of coffee.
