[0055] Reference Figure 1 The refrigerator of the embodiment of the utility model comprises a box body 101 and a door 102. The box body 101 is provided with a refrigerating chamber 103 and a freezing chamber 104. The refrigerating chamber 103 and the freezing chamber 104 are arranged at intervals along the height direction of the box body 101. The upper and lower positional relationship of the refrigerating chamber 103 and the freezing chamber 104 can be set according to requirements, and the refrigerating chamber 103 and the freezing chamber 104 can be opened and closed by the door 102. The temperature in the refrigerating chamber 103 is higher than the temperature in the freezing chamber 104, so that the refrigerating chamber 103 is used to keep the stored items fresh, and the freezing chamber 104 is used to freeze the stored items.

[0056] The door 102 is divided into a first door body 105 and a second door body 106. The first door body 105 is arranged at the opening of the refrigerating chamber 103, and the second door body 106 is arranged at the opening of the freezing chamber 104. The refrigerator is provided with a water intake device 111 and an ice making device 112. The refrigerator can provide low-temperature water to the user through the water intake device 111, and provide ice cubes to the user through the ice making device 112. In combination with the arrangement of the water intake device 111 and the ice making device 112, the water intake device 111 can be arranged on the first door body 105, and the ice making device 112 can be arranged on the first door body 105 or the second door body 106, or in the freezing chamber 104.

[0057] It is understandable that, in some embodiments, the door 102 may also be integrated to simultaneously enclose the refrigerating chamber 103 and the freezing chamber 104 .

[0058] Reference Figure 3 As shown, it can be understood that an operation window 301 is provided on the outer side of the first door body 105, that is, the operation window 301 is located on the side of the first door body 105 away from the refrigerating chamber 103, and the water inlet 109 of the water intake device 111 is located at the operation window 301. More specifically, the operation window 301 is recessed relative to the outer surface of the first door body, the water intake device 111 can be provided at the upper part of the operation window 301, and the water intake 109 is located at the upper part of the operation window 301. The user can place a container at the bottom of the operation window 301 to receive low-temperature water.

[0059] It is understandable that when the ice-making device 112 is disposed on the second door body 106, an ice-taking window is also disposed on the outer side of the second door body 106, and the ice-taking opening of the ice-making device 112 is located in the ice-taking window. More specifically, the ice-taking window is recessed relative to the outer surface of the second door body 106, the ice-making device 112 can be disposed on the upper part of the ice-taking window, and the ice-taking opening is located on the upper part of the ice-taking window, and the user can place a container at the bottom of the ice-taking window to receive ice cubes.

[0060] It is understandable that the ice-making device 112 may also be disposed on the first door body 105, and the ice-taking window and the operation window 301 may be disposed in combination or independently of each other.

[0061] Reference Figure 1 and Figure 2As shown, it can be understood that the refrigerator of the embodiment of the utility model further includes a water box 107, which is used as a water source to supply water to the water intake device 111 and the ice making device 112. The water intake device 111 and the ice making device 112 share a water box 107 to reduce the waste of space in the refrigerator. Specifically, the water box 107 is arranged on the first door body 105, and the water intake device 111 is connected to the water box 107 through the water intake assembly. The height of at least part of the water box 107 is higher than the height of the water intake port 109 of the water intake device 111. The water intake assembly is provided with a control valve 108, and the control valve 108 controls the connection or disconnection of the water intake assembly. When the control valve 108 is opened, the water in the water box 107 can flow out under the action of gravity to reach the water intake port 109 of the water intake device 111. The cooled water is stored in the water box 107. When the user presses the button of the water intake device 111, the cooled water will flow out. The whole system adopts a pure mechanical mechanism, has a stable structure, is not affected by electricity, and can still use the water taking device 111 to take water when the refrigerator is powered off. Since the gravity of water is used, the water path is short, the commonly used water pump 502 is reduced, and the failure rate of the water taking device 111 due to the life of the pump is reduced.

[0062] The refrigerator of the utility model embodiment also includes a pump assembly 110, which is connected to the water box 107 through the water pumping pipeline 403. After the pump assembly 110 is turned on, the water in the water box 107 is transported to the ice making device 112. When the refrigeration system of the refrigerator is running, it will transport cold air to the cooling unit of the ice making device 112. This cooling unit is usually located inside the freezer 104 of the refrigerator and consists of a group of refrigeration pipes and ice molds. When the refrigeration unit is cooled, the water will be guided into the ice mold through an automatic control system. The ice mold is a series of small plastic molds designed to hold a certain amount of water and form ice cubes. The water is cooled and gradually freezes in the ice mold. This process takes a certain amount of time and is usually completed within a few hours. The temperature of the ice making device 112 is usually lower than that of other parts of the refrigerator to ensure that the water can freeze quickly. Once the ice cubes are formed, they will be stored in a special ice storage area of ​​the refrigerator. This area is usually located in the door 102 or the freezer 104 of the refrigerator for easy access by users. The user can open the door 102 and take out ice cubes from the ice storage area for use. The ice making device 112 of some refrigerators is also equipped with an automatic or manually activated ice cube release mechanism to make the ice taking process more convenient.

[0063] It can be understood that the door 102 is rotatably connected to the box body 101 through a hinge, and the connecting shaft 1201 of the hinge is provided with a through hole, and the pumping pipeline 403 passes through the hinge of the door 102, that is, the pumping pipeline 403 is penetrated through the through hole of the connecting shaft 1201 of the hinge, thereby reducing the interference of the rotation of the door 102 on the stability of the pumping pipeline 403. The pumping pipeline 403 is also penetrated through the insulation layer of the box body 101, and supplies water to the ice-making device 112 at the upper end of the freezing chamber 104. Specifically, refer to Figure 1 As shown, the water pumping pipeline 403 starts from the water box 107, extends upward along a suitable path inside the first door body 105 to the hinge above the first door body 105, and then enters the box body 101 and extends downward to the freezing chamber 104. In order to protect the pipes of the water pumping pipeline 403 from damage and avoid frost or condensation caused by the exchange of cold and hot air, the pipes of the water pumping pipeline 403 are usually wrapped with insulating materials, that is, the pipes of the water pumping pipeline 403 are pre-buried in the insulation layer of the box body 101. Figure 2 and Figure 5 As shown, the first door body 105 is provided with a rotation axis hole 201 , the connecting axis 1201 of the hinge is accommodated in the rotation axis hole 201 , and the pipe of the water pumping pipeline 403 is passed through the connecting axis 1201 at the position corresponding to the rotation axis hole 201 .

[0064] Reference Figure 3 and Figure 4 As shown, it can be understood that the first door body 105 is provided with an embedded shell 302, the embedded shell 302 is provided with a recess to form an operation window 301, and the embedded shell 302 is provided with a through hole communicating with the recess, and the water intake device 111 can be inserted through the through hole of the embedded shell 302, so that the water intake port 109 of the water intake device 111 enters the operation window 301. The embedded shell 302 is fixedly installed inside the first door body 105, and it is not easy to move forward and backward or left and right relative to the first door body 105. It can be understood that since there is a foaming layer inside the first door body 105, after the embedded shell 302 is arranged inside the first door body 105, due to the existence of the foaming layer around it, the embedded shell 302 is not easy to move.

[0065] Reference Figure 5As shown, it can be understood that the pump body assembly 110 includes a pre-buried base plate 501, a water pump 502 and a protection box 503, and the pre-buried base plate 501 is installed in the first door body 105, that is, the pre-buried base plate 501 is fixedly installed inside the first door body 105, and it is not easy to move forward and backward or left and right relative to the first door body 105. It can be understood that since there is a foaming layer inside the first door body 105, after the pre-buried base plate 501 is arranged inside the first door body 105, due to the presence of the foaming layer around it, the pre-buried base plate 501 is not easy to move. The water pump 502 is fixedly installed on the pre-buried base plate 501, so that the water pump 502 can be kept relatively fixed with the first door body 105 and is not easy to shake. The protection box 503 is detachably connected to the first door body 105, and the protection box 503 is covered on the water pump 502, so that the water pump 502 is located between the protection box 503 and the pre-buried base plate 501. The protection box 503 is provided with a first hanging ear 504, and the first door body 105 is provided with a first supporting protrusion, and the first hanging ear 504 is hung on the first supporting protrusion to realize the installation of the protection box 503. It is understandable that the first door body 105 and the protection box 503 can also be detachably connected by means of screw connection, buckle connection, etc. After grabbing the protection box 503, the protection box 503 is moved upward so that the first hanging ear 504 is separated from the first supporting protrusion to realize the disassembly of the protection box 503. The first supporting protrusion can support the protection box 503 and can also limit the front and rear directions of the protection box 503, that is, prevent the protection box 503 from falling toward the inside of the box body 101. When the protection box 503 is connected to the embedded bottom plate 501, the protection box 503 can isolate the water pump 502 from other items in the refrigerator to prevent mutual interference, and it is also more beautiful. After the protection box 503 is disassembled, the water pump 502 can be inspected and replaced, which is more convenient for maintenance.

[0066] It is understandable that in some other embodiments, the protection box 503 can also be detachably connected to the embedded base plate 501, and the advantage of hanging the protection box 503 on the first door body 105 is that the operating space is larger, the strength of the connection structure is higher, and it can be more convenient to disassemble and install and improve the connection reliability.

[0067] Reference Figures 6 to 8 As shown, it can be understood that the water box 107 is provided with a water outlet 601, a one-way stop valve 801 is provided at the water outlet 601, and the control valve 108 is detachably connected to the one-way stop valve 801. When the water box 107 is removed from the first door body 105, the one-way stop valve 801 is in a closed state, and the water outlet 601 can be closed, so that the water in the water box 107 cannot flow out from the water outlet 601, which is conducive to maintaining the cleanliness of the inside of the refrigerator and the floor.

[0068] Reference Fig.10As shown, it can be understood that the control valve 108 includes a striker 1001, which is located on the side of the control valve 108 close to the one-way stop valve 801. When the one-way stop valve 801 is installed on the control valve 108, the striker 1001 pushes the valve core in the one-way stop valve 801 to move to the open position, so that the one-way stop valve 801 is in a conducting state. When the water box 107 is taken out, the one-way stop valve 801 is separated from the striker 1001, and the spring valve core 909 in the stop valve helps the valve core 909 return to the closed position to ensure sealing.

[0069] It can be understood that the impact head 1001 includes a protruding portion 1003 and a conducting portion 1004, the conducting portion 1004 is fixedly connected to the valve seat 1007 of the control valve 108 and other positions, the conducting portion 1004 is provided with a conducting hole 1005 for water flow to pass through, the protruding portion 1003 is located on the side of the conducting portion 1004 close to the one-way stop valve 801 and protrudes from the outer surface of the conducting portion 1004, and the conducting hole 1005 is located radially outside the protruding portion 1003. After the water box 107 is installed at a predetermined position of the first door body 105, the protruding portion 1003 relatively enters the water outlet 601 of the water box 107, pushing the valve core in the one-way stop valve 801 to overcome the action of the spring and move so that the water in the water box 107 flows out from the water outlet 601, and the outflowing water flows out after passing through the conducting hole 1005 of the conducting portion 1004.

[0070] Reference Figure 7 As shown, it can be understood that the water box 107 is provided with a second hanging ear 701, and the first door body 105 is provided with a second supporting protrusion, and the second hanging ear 701 is hung on the second supporting protrusion to achieve the installation of the water box 107. It can be understood that the first door body 105 and the water box 107 can also be detachably connected by means of screw connection, snap connection, etc. After taking the water box 107, move the water box 107 upward so that the second hanging ear 701 is separated from the second supporting protrusion to achieve the disassembly of the water box 107. After the water box 107 is replenished with water, it can be directly hung on the second supporting protrusion. The second supporting protrusion can support the water box 107 and can also limit the front and rear directions of the water box 107, that is, prevent the water box 107 from falling toward the inside of the box body 101.

[0071] Reference Figure 7 As shown, it can be understood that the second hanging ear 701 is tilted toward the first door body 105, so that the user can easily put the water box 107 in an oblique direction. Compared with putting the water box 107 in a vertical direction, putting the water box 107 in an oblique direction can reduce the obstruction of the bracket on the first door body 105, obtain a wider operating space, and the moving path of the water box 107 is also shorter.

[0072] Reference Figure 6As shown, it can be understood that the water intake device 111 includes a switch assembly, and the switch assembly can open or close the control valve 108. The switch assembly includes a tongue 602, and the tongue 602 includes a rotating end 603 and a movable end 604. The rotating end 603 is relatively fixed with the first door body 105, and the movable end 604 rotates around the rotating end 603. The control valve 108 includes a press switch 605, and the movable end 604 can cause the press switch 605 to act. Specifically, by pressing the tongue 602, the tongue 602 will move in the direction of the press switch 605 until the movable end 604 of the tongue 602 contacts the press switch 605 and presses the press switch 605 to the maximum position, and then stop pressing the tongue 602. At this time, the signal of the press switch 605 is triggered, and the control valve 108 is in an open state and starts to discharge water.

[0073] It should be noted that, in some other embodiments, the switch assembly may further include a micro switch assembly, which includes a switch support connected to the embedded housing 302 and a micro switch disposed on the switch support. The micro switch support may provide an installation space for the micro switch. The micro switch assembly also includes a push plate disposed on the front side of the micro switch and capable of triggering the micro switch. Specifically, by pressing the push plate, the push plate will move in the direction of the micro switch until the push plate contacts the micro switch and presses the micro switch to the maximum position, then stop pressing the push plate, at which time, the signal of the micro switch is triggered, the control valve 108 is in an open state and starts to discharge water.

[0074] Reference Figure 6 As shown, it can be understood that the switch assembly also includes a mounting plate 606, which is connected to the embedded housing 302, so that the mounting plate 606 and the box door 102 are fixed, and the rotating end 603 of the tongue 602 is rotatably connected to the mounting plate 606. Fig.12 As shown, the mounting plate 606 is provided with a connecting shaft 1201, and the rotating end 603 of the pressing tongue 602 is provided with a connecting hole 1202, and the connecting shaft 1201 is penetrated in the connecting hole 1202, so that the pressing tongue 602 can rotate around the connecting shaft 1201 of the mounting plate 606. In order to facilitate installation, the rotating end 603 of the pressing tongue 602 is also provided with a card interface 1203, and the card interface 1203 penetrates the side wall of the connecting hole 1202, so that the connecting shaft 1201 can enter the connecting hole 1202 through the card interface 1203, so that the pressing tongue 602 can be installed from the front, without the need to be installed in a deformed manner from the side.

[0075] Reference Fig.16As shown, it can be understood that the switch assembly also includes a first elastic member 1601, which is arranged between the mounting plate 606 and the pressing tongue 602. The first elastic member 1601 allows the mounting plate 606 and the pressing tongue 602 to maintain a certain opening and closing angle, so that the movable end 604 of the pressing tongue 602 has a movable distance. After pressing the pressing tongue 602, the first elastic member 1601 can reset the pressing tongue 602, which is convenient for the next pressing action. The first elastic member 1601 can be a metal sheet, one end of the metal sheet is fixedly connected to the mounting plate 606, and the other end abuts against the pressing tongue 602, so that the mounting plate 606 and the pressing tongue 602 maintain a distance. When the user presses the pressing tongue 602, the pressing tongue 602 rotates toward the mounting plate 606, and the metal sheet is squeezed and deformed. When the user releases the pressing tongue 602, the metal sheet returns to its original state and prompts the pressing tongue 602 to reset. It can be understood that the first elastic member 1601 can also be a compression spring or other structure.

[0076] Reference Fig.12 As shown, it can be understood that a limited position structure is provided between the mounting plate 606 and the pressing tongue 602. Specifically, referring to Fig.16 As shown, the mounting plate 606 is provided with a guide hole 1602, and the tongue 602 is provided with a guide block 1204, and the guide block 1204 is penetrated in the guide hole 1602. When the tongue 602 rotates, the guide block 1204 moves along the guide hole 1602. In addition, a limiting portion 1205 is provided at one end of the guide block 1204 away from the tongue 602, and the periphery of the limiting portion 1205 protrudes from the periphery of the guide hole 1602, so that when the tongue 602 rotates, the limiting portion 1205 will not pass through the guide hole 1602, and the limiting portion 1205 abuts against the mounting plate 606, preventing the guide block 1204 from being separated from the guide hole 1602, thereby preventing the first elastic member 1601 from causing the tongue 602 to rebound at an excessively large angle to affect the use.

[0077] Reference Fig. 9 and Fig.10As shown, it can be understood that the control valve 108 has an inlet end 901 and two outlet ends, the inlet end 901 is connected to the water outlet 601, and the two outlet ends are an open end 902 and a normally closed end 903 respectively. The water flowing out of the water box 107 can flow directly from the open end 902 through the inlet end 901, while the normally closed end 903 will block the water flow and cannot flow directly from the normally closed end 903. The control valve 108 is provided with a switch for opening the normally closed end 903, and the switch can be the above-mentioned pressing switch 605 or electromagnetic switch, etc. When the normally closed end 903 is opened, the water flowing out of the water box 107 can flow out from the normally closed end 903. The water intake device 111 is connected to the normally closed end 903 through the water intake assembly, and the water intake device 111 is provided with a structure for operating the switch to open the normally closed end 903, which can be the above-mentioned tongue pressing 602. The pump assembly 110 is connected to the open end 902 through the pumping pipeline 403. When the pump assembly 110 is turned on, water can be pumped to the ice-making device 112. When the pump assembly 110 is closed, the water cannot pass through the pump assembly 110. The control valve 108 adopts a one-in and two-out structure, and is connected to the water intake device 111 and the ice-making device 112 at the same time. The water box 107 is only connected to one control valve 108, that is, a single output end structure is adopted, which simplifies the water circuit of the refrigerator and improves space utilization. When the normally closed end 903 is opened, the open end 902 and the normally closed end 903 can discharge water at the same time, so that the water intake device 111 and the ice-making device 112 can work at the same time.

[0078] Reference Fig. 9 and Fig.10As shown, it can be understood that the control valve 108 includes a valve body 904, a first sealing member 1002 and a valve core 909. The valve body 904 is the main part of the control valve 108, which is used to accommodate and guide the flow of the fluid. The valve core 909 is a key component of the fluid channel in the valve body 904. It can move inside the valve body 904 to change the conduction state of the fluid. The valve body 904 is provided with a valve cavity 1006, and the valve body 904 is also provided with a valve seat 1007, and the valve seat 1007 cooperates with the valve core 909 to form a seal. The valve seat 1007 is located in the valve cavity 1006, the valve core 909 is movably arranged in the valve cavity 1006 and penetrates the valve seat 1007, the first sealing member 1002 is sleeved on the valve body 904 and abuts against the valve seat 1007, the normally closed end 903 and the inlet end 901 are located on opposite sides of the valve seat 1007, and the open end 902 and the inlet end 901 are located on the same side of the valve seat 1007. When the valve core 909 is in the normal position, the first sealing member 1002 abuts against the valve seat 1007 to achieve sealing of the valve seat 1007, so that the water flow entering from the inlet end 901 cannot pass through the valve seat 1007 and flows out from the normally closed end 903. The driving mechanism can be a manual knob, an electric actuator or other driving methods, which is used to control the movement of the valve core 108. When the driving mechanism is not in action, the valve core 909 is in the default position. When the driving mechanism is activated, it moves the valve core 909 to another position, thereby changing the conduction state and making the normally closed end 903 conductive.

[0079] In this embodiment, when the water intake device 111 triggers the switch of the control valve 108, the valve core 909 moves along the axial direction of the valve seat 1007, the first sealing member 1002 is separated from the valve seat 1007, and the water flow entering from the inlet end 901 can flow out from the normally closed end 903 through the valve seat 1007. Since the open end 902 and the inlet end 901 are located on the same side of the valve seat 1007, the water flow entering from the inlet end 901 can flow out directly from the open end 902 without passing through the valve seat 1007. The control valve 108 adopts a purely mechanical mechanism, with a stable structure and is not affected by electricity. When the refrigerator is powered off, the water intake device 111 can still be used to take water. In addition, the water intake device 111 does not require a commonly used water pump 502, but uses the gravity of water itself, which reduces the failure rate of the water intake device 111 due to the pump life problem and reduces the cost.

[0080] The following description will be made by taking the push switch 605 as an example. Fig.10As shown, it can be understood that the push switch 605 includes a push member 1008 and a second elastic member 1009, the push member 1008 can be movably connected to the valve body 904, the two ends of the second elastic member 1009 are respectively against the valve seat 1007 and the valve core 909, and the second elastic member 1009 is used to apply force to the valve core 909 to keep it in a specific position. The switching between the normally open and normally closed states can be controlled by adjusting the tension of the second elastic member 1009. The push member 1008 and the valve core 909 are an integrated structure. After pressing the push member 1008, the push member 1008 moves toward the valve seat 1007, and the valve core 909 moves accordingly, so that the first sealing member 1002 is separated from the valve seat 1007, and the water at the inlet end 901 reaches the normally closed end 903 through the gap between the valve seat 1007 and the first sealing member 1002. After the pressing member 1008 is released, the valve core 909 is reset under the action of the second elastic member 1009 , and the pressing member 1008 moves along with the valve core 909 .

[0081] It can be understood that the pressing member 1008 and the valve core 909 can also be a split structure. In the moving direction of the pressing member 1008, the pressing member 1008 and the valve core 909 maintain a certain distance or maintain abutment. When the pressing member 1008 is subjected to a force, so that the pressing member 1008 moves toward the valve seat 1007, the pressing member 1008 pushes the valve core 909 to move, so that the first sealing member 1002 is separated from the valve seat 1007, connecting the normally closed end 903 and the inlet end 901. When the force that causes the pressing member 1008 to move toward the valve seat 1007 disappears, the valve core 909 is reset under the force of the second elastic member 1009, and the valve core 909 pushes the pressing member 1008 to reset.

[0082] It is understandable that the second elastic member 1009 can also be installed in a manner that one end abuts against the valve body 904 and the other end abuts against the valve core 909 , so as to achieve telescopic movement of the pressing member 1008 and the valve core 909 toward the valve seat 1007 .

[0083] Reference Fig.10 As shown, it can be understood that Fig.10 The up and down direction in is the axial direction of the valve seat 1007. Fig.10 The left and right directions in the figure are the radial directions of the valve seat 1007. The inlet end 901 is located on the upper side of the valve seat 1007, the normally closed end 903 is located on the lower side of the valve seat 1007, the open end 902 is located above the valve seat 1007 and on the right side of the valve seat 1007, the valve core 909 is penetrated through the normally closed end 903, the valve core 909 is provided with a water outlet channel 1101 communicating with the valve cavity 1006, and the pressing member 1008 is provided on the outer peripheral wall of the valve core 909, that is, the pressing member 1008 is a pressing protrusion provided on the outer peripheral wall of the valve core 909. The movement direction of the pressing member 1008 is basically consistent with the water outlet direction, which is conducive to simplifying the structure and improving the space utilization rate.

[0084] Reference Fig.10 and Fig.11 As shown, it can be understood that the valve core 909 includes a core 1014, a barrel 1015 and a plurality of diverter ribs 1016, the barrel 1015 is sleeved on the outside of the core 1014, a water outlet channel 1101 is formed between the barrel 1015 and the core 1014, and a plurality of diverter ribs 1016 are distributed at intervals along the circumference of the valve core 909, each diverter rib 1016 connects the barrel 1015 and the core 1014, and the pressing member 1008 is arranged on the outer peripheral wall of the barrel 1015. The diverter ribs 1016 can make the water outlet more uniform, and the end of the barrel 1015 away from the valve seat 1007 protrudes from the core 1014, so that the water flow at the outlet end of the valve core 909 is more concentrated.

[0085] It should be noted that, in some other embodiments, the axial direction of the valve seat 1007 is close to perpendicular to the line connecting the inlet end 901 to the normally closed end 903. At this time, the normally closed end 903 and the inlet end 901 are located on both sides of the radial direction of the valve seat 1007, the open end 902 is located on one side of the axial direction of the valve seat 1007 but is offset from the valve seat 1007, and the pressing member 1008 is arranged on one side of the axial direction of the valve seat 1007 and outside the valve cavity 1006. After the user presses the pressing member 1008, the pressing member 1008 pushes the valve core 909 to move inside the valve cavity 1006, the first sealing member 1002 is separated from the valve seat 1007, and the water flow at the inlet end 901 can enter the normally closed end 903 through the valve seat 1007. In this embodiment, the movement direction of the pressing member 1008 is substantially perpendicular to the water outlet direction.

[0086] Reference Figure 6 and Fig.12 As shown, it can be understood that the movable end 604 is provided with two protrusions 607, the part of the control valve 108 is inserted between the two protrusions 607, and the push switch 605 is on the movement path of the protrusion 607, so that the protrusion 607 can press the push switch 605. Specifically, the two protrusions 607 are respectively arranged on both sides of the pressing member 1008, and when the pressing tongue 602 rotates toward the mounting plate 606, the two protrusions 607 directly push the pressing member 1008 to move toward the valve seat 1007, opening the normally closed end 903. The two sides of the pressing member 1008 are subjected to force at the same time, so that the pressing member 1008 is subjected to force more evenly and moves more smoothly.

[0087] Reference Fig.10As shown, it can be understood that the control valve 108 also includes a locking tube 1010 and a second sealing member 1011, the locking tube 1010 is inserted at the end of the open end 902, the second sealing member 1011 is arranged between the locking tube 1010 and the open end 902, and the locking tube 1010 is used to connect the pumping pipeline 403. The locking tube 1010 is a mechanical device for pipeline connection, and its main function is to fix and lock the pipe 1010 to ensure the stability and sealing of the pipeline connection. The locking tube 1010 is generally used in pipeline systems that need to be frequently disassembled and connected. They can provide a fast and reliable connection method while reducing the risk of leakage. The locking tube 1010 can be equipped with a locking mechanism, such as a clamp, a clamp or a quick connector, etc., to facilitate the connection of the pipeline of the pumping pipeline 403 with the open end 902. These mechanisms can be further locked after the pipeline is connected to ensure the stability of the connection. During the locking process, the second sealing member 1011 will be compressed to form a good sealing effect.

[0088] Reference Fig. 9 and Fig.10 As shown, it can be understood that the control valve 108 includes a third sealing member 905, the one-way stop valve 801 is inserted into the inner hole of the third sealing member 905, the third sealing member 905 covers the outer wall of the one-way stop valve 801, the impact head 1001 pushes the one-way stop valve 801 to make it in a conducting state, and the water flowing out of the one-way stop valve 801 will be sealed by the third sealing member 905. The third sealing member 905 includes a ring body 1012 and a lip 1013, the lip 1013 is arranged on the inner wall of the ring body 1012, and the lip 1013 is close to the outer wall of the one-way stop valve 801, thereby improving the sealing performance and preventing water from leaking from the gap between the third sealing member 905 and the one-way stop valve 801. In addition, the ring body 1012 has a large thickness and can have a certain strength. When the one-way stop valve 801 is installed, the ring body 1012 is not easy to deform, thereby reducing the difficulty of installation.

[0089] Reference Figure 4 and Fig.13 As shown, it can be understood that a protective cover 401 is provided in the box door 102, the control valve 108 is accommodated in the protective cover 401, the control valve 108 is detachably connected to the protective cover 401, the protective cover 401 is provided with a first outlet 1301, a second outlet 1302 and a third outlet 1303, the one-way stop valve 801 is provided in the first outlet 1301, the normally closed end 903 is provided in the second outlet 1302, and the pumping pipeline 403 is provided in the third outlet 1303.

[0090] Reference Figures 13 to 15As shown, it can be understood that the protective cover 401 includes a cover body 1304 and a cover body 1305, the cover body 1304 is fixedly installed in the first door body 105, the cover body 1305 is located on the side of the cover body 1304 close to the refrigeration chamber 103, the control valve 108 is detachably connected to the cover body 1305, the cover body 1305 is detachably connected to the cover body 1304, and the control valve 108 can be removed together with the cover body 1305, and then the control valve 108 can be taken out from the cover body 1305.

[0091] Specifically, refer to Fig. 9 As shown, the valve body 904 of the control valve 108 is provided with a spiral groove 906, which includes a first groove section 907 arranged along the axial direction of the valve body 904 and a second groove section 908 arranged along the circumferential direction of the valve body 904. The first groove section 907 penetrates to one end surface of the valve body 904, and both ends of the second groove section 908 are blind ends. Fig.14 As shown, the cover body 1305 is provided with a mounting protrusion 1401. During installation, the mounting protrusion 1401 moves axially from the first groove section 907 to the second groove section 908 along the valve body 904, and then the control valve 108 is rotated to allow the mounting protrusion 1401 to move circumferentially from one end of the second groove section 908 to the other end of the valve body 904, thereby realizing the connection between the control valve 108 and the cover body 1305.

[0092] Reference Fig.15 As shown, the housing 1304 is provided with an inner cavity 1501 for accommodating the control valve 108, and the inner wall of the inner cavity 1501 is provided with a clamping hole 1502. Fig.14 As shown, the cover 1305 is provided with a snap-fit ​​protrusion 1402, which is snap-fitted into the snap-fit ​​hole 1502, so as to realize a detachable connection between the cover 1305 and the cover 1304. The cover 1305 also includes a cover portion, which abuts against the end surface of the cover 1304 and closes the inner cavity 1501. Fig.15 As shown, the inner cavity 1501 is divided into a columnar space 1503 and a strip space 1504. The columnar space 1503 is used to place the inlet end 901 and the normally closed end 903, and the strip space 1504 is used to place the open end 902. Fig.14 As shown, the cover 1305 is provided with a limiting protrusion 1403 at a position corresponding to the strip space 1504, and the limiting protrusion 1403 abuts against the side wall of the strip space 1504 away from the columnar space 1503, thereby enhancing the connection reliability between the cover 1305 and the cover 1304. The cover 1304 is also provided with an escape space 1505, which is connected to the strip space 1504, and the position of the escape space 1505 corresponds to the limiting protrusion 1403. It can also be understood that the escape space 1505 is formed by a local area of ​​the side wall of the strip space 1504 away from the columnar space 1503 being recessed, and the user can reach into the escape space 1505 with his hands or tools, pry up the cover 1305, and separate the cover 1305 from the cover 1304.

[0093] Reference Figure 4 and Fig.13 As shown, it can be understood that the protective cover 401 also includes a pipe body 402, and a pipe port through which the water supply pipe 403 passes is arranged on the cover body 1304. The pipe body 402 includes a first side portion 1306, a second side portion 1307 and a pipe portion 1308. The first side portion 1306 and the second side portion 1307 respectively abut against the adjacent two sides of the cover body 1304. The first side portion 1306 is attached to the side wall where the pipe port is located. The pipe portion 1308 is connected to the first side portion 1306 and communicates with the cover body 1304, that is, the position of the pipe portion 1308 corresponds to the pipe port. The water supply pipe 403 is passed through the pipe portion 1308, and then enters the cover body 1304 and is connected to the open end 902. The pipe body 402 and the cover body 1304 are arranged in a split manner. Compared with the integrated arrangement, the split arrangement has a simpler structure, is convenient for manufacturing, and reduces the difficulty of manufacturing. The first side portion 1306 and the second side portion 1307 respectively abut against two adjacent sides of the cover body 1304, which can achieve rapid positioning and connection between the tube body 402 and the cover body 1304, and can also play a protective role to prevent the thermal insulation material from entering the cover body 1304 when the thermal insulation material is injected.

[0094] It is understandable that the refrigerator of the embodiment of the utility model further includes a control module, which is connected to the pump body assembly 110, and the control module can control the opening and closing of the pump body assembly 110. The control module can be the main control board of the refrigerator, or it can be other control devices independent of the main control board of the refrigerator, without specific limitation. When the control module receives the user's opening or closing instruction, it controls the opening or closing of the pump body assembly 110, thereby controlling the opening or closing of the ice-making device 112. For example, the control module can be directly connected to the motor of the water pump 502 through a wiring terminal or a junction box, and can also realize a wireless connection between the control module and the water pump 502 through wireless communication technology (such as Wi-Fi, Bluetooth, ZigBee, etc.).

[0095] Reference Figure 6 As shown, it can be understood that the switch assembly also includes a detection member 608, which can detect the opening action of the depressing tongue 602, that is, when the depressing tongue 602 rotates toward the mounting plate 606 to open the water intake device 111, the detection member 608 detects the position change of the depressing tongue 602, generates and transmits a trigger signal to the control module, and the control module controls the pump body assembly 110 to remain in the closed state. When the water intake device 111 and the ice making device 112 trigger the opening command at the same time, the detection member 608 detects the movement of the depressing tongue 602 and generates a trigger signal. After receiving the trigger signal, the control module will close the pump body assembly 110 and stop the water extraction pipeline 403 of the ice making device 112 from taking water.

[0096] It is understandable that the detent 602 can also be replaced by other triggering members for opening the control valve 108. For example, when the switch assembly includes a button, the triggering member can be a button cap, and the detection member 608 is used to detect the downward movement process of the button cap and transmit the detection signal to the control module.

[0097] Reference Figure 5 As shown, it can be understood that the pump body assembly 110 also includes a normally closed solenoid valve 505, which is arranged on the water pumping pipeline 403. When the water pump 502 is turned on and the normally closed solenoid valve 505 is opened, the water flow at the open end 902 can flow along the water pumping pipeline 403 and enter the ice-making device 112 to make ice. When the normally closed solenoid valve 505 is closed, the water flow at the open end 902 cannot enter the ice-making device 112. After the user takes out the water box 107, the normally closed solenoid valve 505 can close the water pumping pipeline 403. Under the action of atmospheric pressure, the residual water flow in the pipeline connected to the open end 902 will not flow out, thereby avoiding contamination of the internal environment of the refrigerator and improving the user experience.

[0098] It is understandable that in some embodiments, the detection member 608 may be a travel switch, which is fixed to the mounting plate 606 and connected to the control module, and is triggered when the tongue 602 presses the press switch 605. Fig.16 As shown, it can be understood that a mounting position 1603 for accommodating the travel switch is provided on the mounting plate 606, and a snap structure 1604 is provided at the mounting position 1603 to facilitate the installation and removal of the travel switch.

[0099] In some other embodiments, the detection element 608 can also be an infrared sensor, a pressure sensor, an ultrasonic sensor, a magnetic switch, etc. For example, the pressure sensor can detect changes in pressure. When the user presses the switch 605, the sensor detects the increase in pressure and outputs a corresponding signal. The ultrasonic sensor detects the distance of an object by emitting and receiving ultrasonic waves. When the user presses the switch 605, the sensor can detect changes in the position of the object. The magnetic switch uses changes in the magnetic field to detect the state of the switch. When a magnetic object (such as a magnet) approaches or leaves the switch, the switch action can be triggered.

[0100] Reference Fig.17As shown, it can be understood that when the refrigerator is not powered on, the ice-making device 112 in the refrigerator cannot work to make ice, and the water pumping pipeline 403 of the ice-making device 112 cannot work to supply water. The water intake device 111 is a mechanical structure that is not controlled by the circuit, so it can work normally. When the user presses the pressure tongue 602 to draw water, the switch of the control valve 108 is turned on, the water intake water path of the water intake device 111 is opened, and the container can be used to draw water at the outer end of the door 102, that is, after the refrigerator is powered off, the user can still draw water for use without opening the door 102; when the refrigerator is powered on and the user does not press the pressure tongue 602, the water pumping pipeline 403 of the ice-making device 112 can work normally, the water pump 502 pumps water to the ice-making device 112 for ice making, and the water intake device 111 does not discharge water; when the refrigerator is powered on and the user presses the pressure tongue 602, the water pumping pipeline 403 of the ice-making device 112 is closed, the water pump 502 stops pumping water, the water intake water path of the water intake device 111 is opened, and water can be drawn at the outer end of the door 102. When the refrigerator is powered on and the ice-making device 112 is in operation, if the user presses the tongue 602 during operation, the pump assembly 110 stops working, the water intake passage of the water intake device 111 is opened, and water is supplied to the water intake device 111 first.
