[0061] For details, please refer to Figures 1 to 11 The embodiment of the present application provides a water dispenser, including a body 10, a heating unit 20 and a refrigeration unit 30. The body 10 is configured with a storage chamber, which is divided into a refrigeration area 120 and a freezing area 130 by a partition 110. The heating unit 20 is installed on the body 10 for preparing hot water. The refrigeration unit 30 is installed on the body 10 for preparing cold water and supplying cold to the refrigeration area 120 and the freezing area 130. The freezing area 130 is provided with an ice making unit 50, which is configured to prepare ice cubes in the freezing area 130.

[0062] In this embodiment, a storage room is constructed inside the body 10, and the storage room is divided into a refrigerating area 120 and a freezing area 130 by a partition 110, so that food can be refrigerated in the refrigerating area 120 and frozen in the freezing area 130. The heating unit 20 prepares hot water, the refrigerating unit 30 prepares cold water and supplies cold to the refrigerating area 120 and the freezing area 130, and ice cubes are prepared by the ice making unit 50 disposed in the freezing area 130. In this way, the water dispenser can have the functions of preparing hot water, preparing cold water, preparing ice cubes, refrigerating and freezing, making the functions of the water dispenser diverse and improving the applicability of the water dispenser.

[0063] like Figure 1 As shown, based on the width limitation of the body 10 in the water dispenser, the partition 110 is usually horizontally arranged in the storage room to separate the storage room into a refrigerating area 120 and a freezing area 130 distributed vertically. Among them, the freezing area 130 can be located above the refrigerating area 120. Of course, when the width of the body 10 is sufficient, the partition 110 can be vertically arranged in the storage room to separate the storage room into the refrigerating area 120 and the freezing area 130 distributed horizontally.

[0064] Among them, the partition 110 can be made of heat-insulating material or thermal insulation material to prevent the temperatures of the refrigeration area 120 and the freezing area 130 from interfering with each other, thereby preventing the cold air in the freezing area 130 from being transferred to the refrigeration area 120, causing the temperature of the refrigeration area 120 to be lower and the temperature of the freezing area 130 to be higher.

[0065] like Figure 2 As shown, in some embodiments, the refrigeration unit 30 includes a compressor 310, a heat exchanger 320, and a first evaporator 330. The compressor 310 is mounted on the machine body 10. The heat exchanger 320 is mounted on the machine body 10, and the refrigerant inlet end of the heat exchanger 320 is connected to the refrigerant outlet end of the compressor 310 through a refrigerant pipeline. The first evaporator 330 is mounted in the freezing area 130, and the refrigerant inlet end of the first evaporator 330 is connected to the refrigerant outlet end of the heat exchanger 320 through a refrigerant pipeline, and a throttling device is installed on the refrigerant pipeline between the first evaporator 330 and the heat exchanger 320, and the refrigerant outlet end of the first evaporator 330 is connected to the refrigerant inlet end of the compressor 310 through a refrigerant pipeline.

[0066] It is understandable that the compressor 310 is used to form a high-temperature and high-pressure gaseous refrigerant. After the high-temperature and high-pressure gaseous refrigerant flows into the heat exchanger 320 from the refrigerant pipeline, it can form a high-temperature and high-pressure liquid refrigerant after phase change in the heat exchanger 320. The high-temperature and high-pressure liquid refrigerant is throttled and depressurized from the refrigerant pipeline to form a low-temperature and low-pressure liquid refrigerant, and flows into the first evaporator 330. The low-temperature and low-pressure liquid refrigerant exchanges heat with the freezing zone 130 through the first evaporator 330, thereby transferring the cold to the freezing zone 130, and providing cold for the freezing zone 130. At the same time, the low-temperature and low-pressure liquid refrigerant can be phase-changed into a low-temperature and low-pressure gaseous refrigerant in the first evaporator 330. The low-temperature and low-pressure gaseous refrigerant flows back to the compressor 310, completing a round of refrigerant circulation.

[0067] The throttling device may be a capillary tube, which is used to throttle and reduce the pressure of the high-temperature and high-pressure liquid refrigerant discharged from the heat exchanger 320 to form a low-temperature and low-pressure liquid refrigerant. Of course, the throttling device may also be an expansion valve, etc., and the throttling device may be reasonably selected based on cost and other factors.

[0068] The compressor 310, the heat exchanger 320, and the capillary tube can all be arranged inside the machine body 10, and the heat exchanger 320 is located near the heat dissipation structure of the machine body 10, so as to release heat at the position of the heat exchanger 320 to realize the phase change of the refrigerant. The compressor 310, the heat exchanger 320, and the capillary tube can also be arranged outside the machine body 10. In this case, the compressor 310, the heat exchanger 320, and the capillary tube can be arranged in a chassis, and connected to the first evaporator 330 through the refrigerant pipeline to realize the refrigerant circulation.

[0069] Please continue reading Figure 2 In some embodiments, the refrigeration unit 30 further includes a second evaporator 340. The second evaporator 340 is installed in the refrigeration area 120, and the refrigerant inlet end of the second evaporator 340 is connected to the refrigerant outlet end of the first evaporator 330 through a refrigerant pipeline, and the refrigerant outlet end of the second evaporator 340 is connected to the refrigerant inlet end of the compressor 310 through a refrigerant pipeline.

[0070] It is understandable that after the low-temperature and low-pressure liquid refrigerant undergoes heat exchange with the freezing zone 130 through the first evaporator 330, a portion of it will be phase-changed into a low-temperature and low-pressure gaseous refrigerant, and a portion of the low-temperature and low-pressure liquid refrigerant that has not undergone phase change can flow into the second evaporator 340 through the refrigerant pipeline. The mixture of the low-temperature and low-pressure liquid refrigerant and the gaseous refrigerant can undergo heat exchange with the second evaporator 340, and transfer the cold to the refrigeration zone 120, thereby providing cold for the refrigeration zone 120. At the same time, the low-temperature and low-pressure liquid refrigerant can be phase-changed into a low-temperature and low-pressure gaseous refrigerant in the second evaporator 340. The low-temperature and low-pressure gaseous refrigerant flows back to the compressor 310, completing a round of refrigerant circulation.

[0071] Please continue reading Figure 2 In some embodiments, the refrigeration unit 30 further includes a cold water tank 360 and a third evaporator 350. The cold water tank 360 is mounted on the body 10. The third evaporator 350 is mounted on the cold water tank 360, and the refrigerant inlet end of the third evaporator 350 is connected to the refrigerant outlet end of the second evaporator 340 through a refrigerant pipeline, and the refrigerant outlet end of the third evaporator 350 is connected to the refrigerant inlet end of the compressor 310 through a refrigerant pipeline.

[0072] After the low-temperature and low-pressure liquid refrigerant is heat-exchanged with the freezing zone 130 through the second evaporator 340, a part of it will be phase-changed into a low-temperature and low-pressure gaseous refrigerant, and a part of the low-temperature and low-pressure liquid refrigerant that has not undergone phase change can flow into the third evaporator 350 through the refrigerant pipeline. The mixture of this part of the low-temperature and low-pressure liquid refrigerant and the gaseous refrigerant can be heat-exchanged with the third evaporator 350, and the cold energy is transferred to the cold water tank 360, so as to provide cold water for the cold water tank 360. At the same time, the low-temperature and low-pressure liquid refrigerant can be phase-changed into a low-temperature and low-pressure gaseous refrigerant in the third evaporator 350. The low-temperature and low-pressure gaseous refrigerant flows back to the compressor 310, completing a round of refrigerant circulation.

[0073] Based on the above refrigerant circuit arrangement, the high-temperature and high-pressure gaseous refrigerant generated by the compressor 310 passes through the heat exchanger 320 and the capillary tube, and the low-temperature and low-pressure liquid refrigerant formed can sequentially provide cooling for the first evaporator 330, the second evaporator 340, and the third evaporator 350. Thus, cooling for the freezing area 130, cooling for the refrigeration area 120, and cooling for the cold water tank 360 is achieved. Therefore, the refrigerant system can simultaneously achieve the freezing function, the refrigeration function, and the function of preparing cold water.

[0074] Generally speaking, the freezing temperature of the freezing area 130 is -10°C to 0°C (degrees Celsius), the refrigeration temperature of the refrigerating area 120 is 8°C to 15°C, and the water temperature of the drinking water in the cold water tank 360 is 4°C to 8°C. Based on the arrangement of the above refrigerant circuit, the freezing area 130, the refrigerating area 120 and the cold water tank 360 are provided with corresponding cold amounts in turn to ensure the normal operation of the water dispenser.

[0075] In this embodiment, there is no restriction on the models of the compressor 310, the heat exchanger 320, the throttling device, the first evaporator 330, the second evaporator 340 and the third evaporator 350, as long as they can realize their own functions.

[0076] like Figure 3 As shown, in some embodiments, the heating unit 20 includes a hot water tank 210 and a heating unit. The hot water tank 210 is installed on the machine body 10. The heating unit is installed on the hot water tank 210 and is used to heat the drinking water stored in the hot water tank 210.

[0077] The heating unit disposed in the hot water tank 210 can heat the drinking water to realize the function of the water dispenser to prepare hot water. The heating unit can be an electric heater, which is built into the hot water tank 210 to directly heat the drinking water in the hot water tank 210. The heating unit can also be an electric heating wire, which can be wound around the inner surface and / or outer surface of the hot water tank 210 to heat the drinking water in the hot water tank 210.

[0078] Please continue reading Figure 3 In some embodiments, the water outlet of the cold water tank 360 is connected to the water outlet of the body 10 and the water inlet of the hot water tank 210 through a cold water outlet pipe, and the water outlet of the hot water tank 210 is connected to the water outlet of the body 10 through a hot water outlet pipe.

[0079] Based on the water outlet of the cold water tank 360 being connected to the water outlet of the machine body 10, cold water can be discharged from the water outlet of the machine body 10 to facilitate the supply of cold water. Based on the water outlet of the cold water tank 360 being connected to the hot water tank 210, drinking water in the cold water tank 360 can be transported to the hot water tank 210 and heated by the heating unit to form hot water. Based on the water outlet of the hot water tank 210 being connected to the water outlet of the machine body 10, hot water can be discharged from the water outlet of the machine body 10 to facilitate the supply of hot water.

[0080] like Figure 3As shown, the cold water tank 360 can be located above the hot water tank 210. Thus, the drinking water in the cold water tank 360 can be directly transported to the hot water tank 210 by gravity. Since the cold water tank 360 is located above the hot water tank 210, a valve can be provided on the pipeline between the cold water tank 360 and the water outlet tank to control the on-off of the pipeline. Since the cold water tank 360 and the hot water tank 210 are connected to each other, only one water source needs to be configured to provide drinking water for the cold water tank 360, and there is no need to configure a separate water source for the hot water tank 210.

[0081] like Figure 1 and Figure 4 As shown, in some embodiments, the storage room is formed with a take-out opening 140 on the machine body 10, and a door assembly 40 is rotatably mounted on the machine body 10, wherein the door assembly 40 includes a door body 410, a lining plate 420, a heat-insulating layer 430, and a magnetic attraction member 440. The lining plate 420 is mounted on a side of the door body 410 facing the take-out opening 140, and a receiving cavity is formed between the lining plate 420 and the door body 410. The heat-insulating layer 430 is mounted in the receiving cavity.

[0082] The food in the refrigerator and freezer can be taken out and placed based on the access opening 140 on the body 10. The door assembly 40 is used to control the opening and closing of the access opening 140, so as to achieve the effect of sealing and keeping cold.

[0083] Specifically, the door assembly 40 forms a receiving cavity between the door body 410 and the lining plate 420. By arranging the heat preservation layer 430 in the receiving cavity, the heat preservation function of the door assembly 40 is realized to prevent the cold energy of the freezing area 130 and the refrigerating area 120 from being lost from the door assembly 40.

[0084] like Figure 4 As shown, in some embodiments, a plurality of connecting posts are configured on the door body 410, and threaded holes are formed on the connecting posts. A plurality of connecting holes are configured on the lining plate 420, and each connecting hole corresponds to a threaded hole of a connecting post. The connecting holes and the threaded holes are connected by fasteners to achieve a stable connection between the lining plate 420 and the door body 410.

[0085] Please continue reading Figure 4 A magnetic member 440 is installed on one side of the lining plate 420 facing the access opening 140, and is used for magnetic connection to the machine body 10. The magnetic member 440 on the lining plate 420 is used to connect the lining plate 420 and the machine body 10, so as to realize a detachable connection between the two.

[0086] like Figure 4As shown, the lining plate 420 can be roughly in the shape of an 8, and a partition section is provided in the middle thereof. The partition section corresponds to the partition 110, thereby dividing the door assembly 40 into an area of ​​the enclosed refrigerated area 120 and an area of ​​the enclosed frozen area 130. Among them, a magnetic attraction member 440 is provided on each side of the 8-shaped lining plate 420. Among them, the magnetic attraction member 440 can be a magnet, and based on the fact that the body 10 is made of a magnetic metal material, the door assembly 40 can be directly adsorbed to the body 10 through the magnet, so that the door assembly 40 can be reliably closed. When the body 10 is made of materials such as plastic, a corresponding magnet can be installed in the body 10 near the access port 140, and the door assembly 40 can be reliably closed based on the magnetic connection between the magnets.

[0087] The door assembly 40 can be hinged to the machine body 10 through the door body 410 to achieve a rotational connection between the door assembly 40 and the machine body 10. The door assembly 40 can also be hinged to the machine body 10 by hingedly connecting the lining plate 420 to the machine body 10 to achieve a rotational connection between the door assembly 40 and the machine body 10.

[0088] like Figures 5 to 7 As shown, in some embodiments, an ice making unit 50 is disposed in the freezing area 130, and the ice making unit 50 includes a housing 510, an ice tray 520, and a water replenishment mechanism 70. The housing 510 is installed in the freezing area 130. The ice tray 520 has an ice making groove 530, and the ice tray 520 is installed in the housing 510. The water replenishment mechanism 70 is configured to inject drinking water into the ice making groove 530.

[0089] For example, when the space of the freezing area 130 is large enough, there is still storage space in the freezing area 130 after the ice making unit 50 is installed in the freezing area 130, so that the freezing area 130 can have both the freezing function of food storage and the ice making function of making ice cubes. In this case, the water dispenser will have the functions of making hot water, making cold water, making ice cubes, refrigerating and freezing, making the water dispenser more versatile and better meeting the needs of users.

[0090] For example, when the space of the freezing area 130 is limited, and there is no remaining storage space in the freezing area 130 after the ice making unit 50 is installed in the freezing area 130, the freezing area 130 can only prepare ice cubes. In this case, the water dispenser will have the functions of preparing hot water, preparing cold water, preparing ice cubes, and refrigerating. The water dispenser has diversified functions to better meet user needs.

[0091] Based on the structure of preparing ice cubes, drinking water can be added to the ice making groove 530 of the ice tray 520 through the water replenishing mechanism 70. Under the action of the first evaporator 330, the drinking water in the ice making groove 530 can be gradually frozen into ice cubes.

[0092] like Figure 5As shown, the water replenishment mechanism 70 is located outside the housing 510, and the first evaporator 330 can be arranged inside the housing 510. A water replenishment port can be configured on the upper surface of the housing 510, and water is replenished to the ice tray 520 through the water replenishment port. By placing the water replenishment mechanism 70 outside the housing 510, it is possible to prevent the internal temperature of the water replenishment mechanism 70 from being too low, so that drinking water is frozen in the water replenishment mechanism 70 and causes blockage.

[0093] like Figure 7 and Figure 8 As shown, in some embodiments, the ice-making unit 50 further includes a transmission mechanism 60 , which is installed in the housing 510 , and the ice tray 520 is installed on the transmission mechanism 60 , so as to drive the ice tray 520 to flip through the transmission mechanism 60 .

[0094] Based on the structure for preparing ice cubes, drinking water can be added to the ice making groove 530 of the ice tray 520 through the water replenishment mechanism 70. Under the action of the first evaporator 330, the drinking water in the ice making groove 530 can be gradually frozen into ice cubes. Among them, the transmission mechanism 60 is located above the ice storage box 560. After the ice cubes are made, the transmission mechanism 60 drives the ice tray 520 to flip, thereby pouring the ice cubes in the ice tray 520 into the ice storage box 560 for user use.

[0095] like Figure 6 As shown, each ice tray 520 can be provided with a plurality of ice making grooves 530. Based on the transmission direction of the transmission mechanism 60, the water replenishment mechanism 70 can be located at a forward position in the transmission direction. After the water replenishment mechanism 70 replenishes water, the transmission mechanism 60 can drive one ice tray 520 to move forward and replenish water for the next ice tray 520.

[0096] like Figure 8 As shown, in some embodiments, the transmission mechanism 60 includes a first rotating shaft 610, a second rotating shaft 620, and a transmission chain 630. The first rotating shaft 610 and the second rotating shaft 620 are spaced apart in the housing 510. The transmission chain 630 is sleeved between the first rotating shaft 610 and the second rotating shaft 620, and is used to drive the transmission chain 630 to transmit through the rotation of the first rotating shaft 610 and / or the second rotating shaft 620. Among them, at least two ice trays 520 are provided, and at least two ice trays 520 are installed on the transmission chain 630 at intervals along the transmission direction.

[0097] The transmission chain 630 is driven to transmit based on the rotation of the first rotating shaft 610 and the second rotating shaft 620. After the transmission chain 630 is sleeved on the first rotating shaft 610 and the second rotating shaft 620, it will have an upper part and a lower part. When the ice tray 520 is located in the upper part, the notch of the ice making groove 530 of the ice tray 520 faces upward. In this way, the ice making groove 530 can store drinking water and form ice cubes under the action of the second evaporator 340. When the ice tray 520 is located in the lower part, the notch of the ice making groove 530 of the ice tray 520 faces downward. In this way, the ice tray 520 can be turned over and the ice cubes in the ice making groove 530 can be poured into the ice storage box 560 below to achieve the storage of ice cubes.

[0098] The transmission chain 630 may be a belt. The transmission chain 630 is directly sleeved on the first rotating shaft 610 and the second rotating shaft 620, so as to drive the belt transmission through the first rotating shaft 610 or the second rotating shaft 620. The transmission chain 630 may also be a chain. Gears are configured on the outer surfaces of the first rotating shaft 610 and the second rotating shaft 620, so that the gears are meshed with the chain, and the chain transmission can be driven through the first rotating shaft 610 or the second rotating shaft 620.

[0099] like Figure 6 and Figure 7 As shown, in some embodiments, a panel 540 is constructed on one side of the shell 510 facing the collective door assembly 40, and the first rotating shaft 610 and the second rotating shaft 620 are both rotatably mounted on the panel 540, wherein at least one of the first rotating shaft 610 and the second rotating shaft 620 passes through the panel 540 and is connected to a torsion member 640 outside the panel 540.

[0100] The arrangement based on the panel 540 can be used to rotatably connect the first rotating shaft 610 and the second rotating shaft 620. The first rotating shaft 610 and the second rotating shaft 620 are rotatably connected to the inner surface of the housing 510 at one end away from the panel 540. A support member can be provided on the inner surface of the housing 510. A circular notch can be provided on the support member to rotatably support the first rotating shaft 610 or the second rotating shaft 620. A bearing can also be provided on the support member, and the bearing is used to rotatably connect the first rotating shaft 610 or the second rotating shaft 620.

[0101] The first rotating shaft 610 passes through the panel 540 and is connected to the twisting member 640 outside the panel 540, so that the user can hold the twisting member 640 and rotate it to drive the first rotating shaft 610 to rotate. In this way, the transmission chain 630 can be driven to transmit the ice tray 520 or flip the ice tray 520.

[0102] Alternatively, the second rotating shaft 620 is passed through the panel 540 and connected to the twisting member 640 outside the panel 540, so that the user can hold the twisting member 640 and rotate it to drive the second rotating shaft 620 to rotate. In this way, the transmission chain 630 can be driven to transmit the ice tray 520 or flip the ice tray 520.

[0103] The panel 540 can be made of a transparent material. Therefore, it is possible to observe at the panel 540 whether the ice tray 520 is in a suitable water replenishment position after the torsion member 640 twists the drive transmission chain 630 for transmission. Alternatively, it is possible to observe at the panel 540 whether the ice tray 520 is in a flipped state. Alternatively, it is possible to observe at the panel 540 the amount of water replenishment, so as to control the amount of water replenishment and prepare ice cubes of different sizes.

[0104] In other embodiments of the present application, the first rotating shaft 610 or the second rotating shaft 620 may be driven to rotate by a motor to drive the transmission chain 630. The motor may use a gear set to drive the first rotating shaft 610 or the second rotating shaft 620 to rotate; or the motor may drive the first rotating shaft 610 or the second rotating shaft 620 to rotate through a worm gear; or the motor may be directly coaxially connected to the first rotating shaft 610 or the second rotating shaft 620 to drive the first rotating shaft 610 or the second rotating shaft 620 to rotate.

[0105] Please continue reading Figure 6 and Figure 7 In some embodiments, the ice-making unit 50 further includes an ice storage box 560 , the panel 540 is formed with a mounting notch 550 , and the ice storage box 560 is slidably installed in the shell 510 from the mounting notch 550 , wherein a grip portion 570 is constructed on the side of the ice storage box 560 facing the door assembly 40 .

[0106] The mounting notch 550 on the panel 540 is used to slide the ice storage box 560 so that the ice storage box 560 can be inserted into the housing 510 to store ice cubes. The grip 570 is used to extract the ice storage box 560, which is convenient for taking out ice cubes and putting in the ice storage box 560.

[0107] like Fig. 9 and Fig.10 As shown, in some embodiments, the water replenishment mechanism 70 includes a button 710, a water replenishment pipeline and a seal. The button 710 is installed on the panel 540. The water replenishment pipeline is constructed with a water replenishment inlet pipe 720, a water replenishment outlet pipe 730 and a conducting pipe 740 for conducting the water replenishment inlet pipe 720 and the water replenishment outlet pipe 730. The water replenishment inlet pipe 720 is connected to the cold water tank 360 of the refrigeration unit 30, and the water replenishment outlet pipe 730 is configured to inject drinking water into the ice making groove 530. The seal is slidably installed in the conducting pipe 740, and the seal is connected to the button 710, and is used to drive the seal to move in the conducting pipe 740 through the button 710 to control the on and off of the conducting pipe 740.

[0108] By pressing the button 710, the seal is driven to slide in the conduction tube 740 to control the on-off of the conduction tube 740. It is understandable that when the button 710 is not pressed, the seal is in a state of sealing the conduction tube 740. At this time, the water replenishment inlet pipe 720 and the water replenishment outlet pipe 730 are not connected, and the water replenishment mechanism 70 cannot add drinking water to the ice tray 520. When the user presses the button 710, the seal slides in the conduction tube 740 to put the conduction tube 740 in a conducting state. At this time, the water replenishment inlet pipe 720 and the water replenishment outlet pipe 730 are connected through the conduction tube 740, and the water replenishment mechanism 70 can add drinking water to the ice tray 520 to facilitate the preparation of ice cubes.

[0109] Since the panel 540 is made of a transparent material, the timing of releasing the button 710 can be determined based on observation to control the amount of water replenishment, thereby preparing ice cubes of different sizes. It is understandable that the user can control the water level in the ice tray 520 according to their own needs, so as to form ice cubes of appropriate sizes in the ice making groove 530, which is more suitable for the actual use of the user.

[0110] Among them, the water supply inlet pipe 720 is connected to the cold water tank 360, so the drinking water with a lower temperature in the cold water tank 360 can be used as a water source for preparing ice cubes. Since the room temperature in the cold water tank 360 is relatively low, approximately 4°C to 8°C, which is lower than the water temperature at room temperature, the efficiency of preparing ice cubes can be greatly improved, so that drinking water can form ice cubes faster.

[0111] When the door assembly 40 is in a closed state, there is a gap of a certain width between the panel 540 and the door assembly 40 to prevent the door assembly 40 from touching the button 710 and causing erroneous water replenishment.

[0112] At the same time, by pressing the button 710, drinking water can be added to the ice making groove 530 of the ice tray 520, so the user does not need to take out the ice tray 520 for water replenishment during the ice making process, which simplifies the ice making process, improves the convenience of ice making, and is simple and quick to operate.

[0113] Please continue reading Fig.10In some embodiments, the conducting pipe 740 has a first section 7410 connected to the water replenishment inlet pipe 720 and a second section 7420 connected to the water replenishment outlet pipe 730. The connection between the first section 7410 and the second section 7420 forms a sealing opening 7430, wherein the sealing member includes a first push rod 7510 and a second push rod 7520. The first push rod 7510 is slidably mounted on the first section 7410, and the first push rod 7510 abuts against the button 710. The second push rod 7520 is slidably mounted on the second section 7420 and closes the sealing opening 7430. The second push rod 7520 abuts against the first push rod 7510, and is used to drive the second push rod 7520 to move in the second section 7420 through the first push rod 7510 to control the opening and closing of the sealing opening 7430.

[0114] It can be understood that the first section 7410 of the conducting pipe 740 is used to connect the water replenishment inlet pipe 720, and the second section 7420 of the conducting pipe 740 is used to connect the water replenishment outlet pipe 730. When the sealing member does not seal the sealing port 7430 between the first section 7410 and the second section 7420, the first section 7410 and the second section 7420 are connected to each other. At this time, the water replenishment inlet pipe 720 and the water replenishment outlet pipe 730 can be connected to each other through the conducting pipe 740 to realize water replenishment of the ice making groove 530 of the ice tray 520. When the sealing member seals the sealing port 7430 between the first section 7410 and the second section 7420, the first section 7410 and the second section 7420 are in a non-conductive state. At this time, the water replenishment inlet pipe 720 and the water replenishment outlet pipe 730 are not connected, and water replenishment is stopped.

[0115] Specifically, by pressing the first push rod 7510 through the button 710 , the first push rod 7510 can drive the second push rod 7520 to slide in the second section 7420 to control the opening and closing of the sealing port 7430 .

[0116] like Fig.10 As shown, the conducting pipe 740 is a horizontally arranged pipe, having a first section 7410 and a second section 7420 arranged on the left and right. The water replenishment inlet pipe 720 and the water replenishment outlet pipe 730 are vertically arranged pipes. The water replenishment inlet pipe 720 is connected to the upper surface of the first section 7410, and the water replenishment outlet pipe 730 is connected to the lower surface of the second section 7420. The conducting pipe 740 is defined as the connection between the first section 7410 and the second section 7420 at a position close to the water replenishment outlet pipe 730, and a sealing port 7430 is formed.

[0117] The diameter of the first push rod 7510 is smaller than the inner diameter of the first section 7410 to prevent the first push rod 7510 from closing the first section 7410. The diameter of the second push rod 7520 can be adapted to the outer diameter of the second section 7420 so that the second push rod 7520 can close the sealing opening 7430. Alternatively, the second flexible member 7570 can be sleeved on the outside of the second push rod 7520 to close the sealing opening 7430 through the second flexible member 7570.

[0118] Please continue reading Fig.10 In some embodiments, a first sealing joint 7530 is installed at one end of the first section 7410 away from the second section 7420, and a first flexible member 7540 is installed in the first sealing joint 7530. The first flexible member 7540 extends toward the button 710 and abuts against the button 710, wherein the first flexible member 7540 forms a first connecting cavity 7550 connected to the first section 7410, and the first push rod 7510 is clamped in the first connecting cavity 7550.

[0119] It is understandable that the end of the first section 7410 away from the second section 7420 can be sealed by the first sealing joint 7530 and the first flexible member 7540. The first flexible member 7540 is brought into contact with the button 710, and the first push rod 7510 is clamped in the first connecting cavity 7550 of the first flexible member 7540. Then, the first push rod 7510 can be driven by the button 710 to slide toward the second push rod 7520, so as to drive the second push rod 7520 to move.

[0120] When the button 710 is pressed, the first flexible member 7540 can adapt to the pressing of the button 710 by deforming itself, so that the first flexible member 7540 can cooperate with the first sealing joint 7530 to keep the end of the first section 7410 away from the second section 7420 in a sealed state at all times to prevent water leakage.

[0121] like Fig.10 As shown, the first sealing joint 7530 is sleeved on the outside of the first section 7410, and a mounting hole is formed in the first sealing joint 7530. The first flexible member 7540 is mounted on the first sealing joint 7530 from the inner side of the first sealing joint 7530, and passes through the mounting hole to abut against the button 710. Thus, the first sealing joint 7530 and the first flexible member 7540 are sealed and connected to the first section 7410, and the abutment with the button 710 is achieved.

[0122] In some embodiments, a second sealing joint 7560 is installed at one end of the second section 7420 away from the first section 7410, a second flexible member 7570 is installed in the second sealing joint 7560, the second flexible member 7570 extends in the direction of the sealing opening 7430, and the second flexible member 7570 abuts against the first push rod 7510 and closes the sealing opening 7430. The second flexible member 7570 forms a second connecting cavity 7580 connected to the through hole 7590 of the second sealing joint 7560, the first end of the second push rod 7520 is clamped in the second connecting cavity 7580, and the second end of the second push rod 7520 passes through the second sealing joint 7560 from the through hole 7590.

[0123] It is understandable that the second section 7420 can be sealed at one end away from the first section 7410 by the second sealing joint 7560, and the sealing opening 7430 can be sealed by the second flexible member 7570, and the second flexible member 7570 can be abutted against the first push rod 7510. The second push rod 7520 is clamped into the second connecting cavity 7580 of the second flexible member 7570, and the second flexible member 7570 and the second push rod 7520 can be pushed by the first push rod 7510 to slide in a direction away from the sealing opening 7430, so that the sealing opening 7430 is in a conducting state.

[0124] When the button 710 is pressed, the second flexible member 7570 can adapt to the position movement of the button 710 and the first push rod 7510 through its own deformation, so that the second flexible member 7570 can move away from the sealing port 7430 and connect the water replenishment inlet pipe 720 and the water replenishment outlet pipe 730.

[0125] like Fig.10 As shown, the second sealing joint 7560 is sleeved on the outside of the second section 7420, and the second sealing joint 7560 is formed with a through hole 7590 for passing the second push rod 7520. One end of the second flexible member 7570 is fixed to the second section 7420 through the second sealing joint 7560, and the other end of the second flexible member 7570 extends toward the sealing opening 7430, and after passing through the entire second section 7420, the sealing opening 7430 is closed.

[0126] Please continue reading Fig.10 In some embodiments, an elastic member 760 is disposed in the second connecting cavity 7580, and the elastic member 760 is sleeved on the second push rod 7520, wherein the first end of the elastic member 760 abuts against a baffle constructed on the peripheral side of the second push rod 7520, and the second end of the elastic member 760 abuts against the second sealing joint 7560.

[0127] When the button 710 is pressed, the first push rod 7510, the second flexible member 7570 and the second push rod 7520 will slide in a direction away from the button 710. At this time, the elastic member 760 gradually contracts, and the second flexible member 7570 deforms to make the sealing port 7430 conductive, so that the ice tray 520 can be replenished with water. When the user releases the button 710, under the self-restoring effect of the elastic member 760, the second push rod 7520, the second flexible member 7570 and the first push rod 7510 can slide in the direction of the button 710, and the button 710 returns to the initial state. At this time, the spring gradually extends, and the second flexible member 7570 deforms to close the sealing port 7430, and the water replenishment stops.

[0128] The elastic member 760 may be a spring, which is sleeved on the second push rod 7520, and the two ends of the spring respectively abut against the baffle plate around the second push rod 7520 and the second sealing joint 7560. When the button 710 is not pressed, the second push rod 7520, the second flexible member 7570 and the first push rod 7510 can always have a force acting in the direction of the button 710 under the action of the spring, thereby ensuring the reliability of the sealing of the second flexible member 7570.

[0129] The baffle plate may be arranged in a ring shape around the second push rod 7520 and may be integrally formed with the second push rod 7520 .

[0130] In some embodiments, the second section 7420 is further configured with an extension tube 770, which is in communication with the water replenishment outlet pipe 730, wherein the extension tube 770 is in communication with the external environment of the housing 510. Based on the design of the extension tube 770, when the conducting tube 740 is in a closed state, the extension section enables the water replenishment outlet pipe 730 to be in communication with the external environment of the housing 510, thereby balancing the air pressure of the water replenishment outlet pipe 730, so that the drinking water in the water replenishment outlet pipe 730 can be completely discharged into the ice making groove 530 of the ice tray 520. In this way, it is possible to prevent the drinking water from being retained in the water replenishment outlet pipe 730 and freezing, resulting in the blockage of the water replenishment outlet pipe 730.

[0131] The external environment of the housing 510 may be an area inside the body 10 and outside the housing 510. Alternatively, the external environment of the housing 510 may be a user's living area outside the body 10.

[0132] In other embodiments of the present application, a solenoid valve may be provided on the conducting tube 740 to control the on and off of the conducting tube 740. The solenoid valve may control the amount of water replenishment based on a counter, etc., to prepare ice cubes of a suitable number and size. It is understandable that when water needs to be replenished for three ice cube trays 520, 3 may be input on the counter, and the solenoid valve controls the conducting tube 740 to provide the amount of drinking water for replenishing the three ice cube trays 520 after the conduction.

[0133] like Fig.11 As shown, in some embodiments, an insulation box 150 is provided in the storage room, and a partition 110 is provided in the insulation box 150 to separate the insulation box 150 into a first cavity 160 and a second cavity 170. A refrigeration liner 180 is provided in the first cavity 160 to form a refrigeration area 120, and a freezing liner 190 is provided in the second cavity 170 to form a freezing area 130.

[0134] Based on the design of the thermal insulation box 150 and the refrigeration liner 180 and the freezing liner 190, a heat preservation effect can be achieved, ensuring that the freezing area 130 and the refrigeration area 120 can be kept at a lower temperature under the action of the first evaporator 330 and the second evaporator 340.

[0135] The heat preservation box 150 and the aforementioned heat preservation layer 430 can both be made of heat preservation foam. Of course, they can also be made of other heat preservation materials as long as both have heat preservation performance.

[0136] The partition 110 may be integrally formed in the thermal insulation box 150 to separate the thermal insulation box 150 into a first cavity 160 and a second cavity 170 to respectively accommodate a refrigeration liner 180 and a freezing liner 190 to achieve refrigeration, freezing and ice making functions.

[0137] The refrigerated liner 180 and the frozen liner 190 can be integrally formed, and partitioned by an inner liner, so as to form an inner liner structure with a refrigerated area 120 and a frozen area 130. The refrigerated liner 180 and the frozen liner 190 can also be a split design, and the refrigerated liner 180 and the frozen liner 190 are independently installed in the first cavity 160 and the second cavity 170 respectively.

[0138] In other embodiments of the present application, the partition 110 may not be provided in the thermal insulation box 150, and only an independent cavity exists in the thermal insulation box 150. The inner liner may be directly provided in the thermal insulation box 150, and the partition 110 may be provided in the inner liner. Thus, the space inside the inner liner is divided into a refrigeration area 120 and a freezing area 130 by the partition 110, so as to realize the functions of refrigeration, freezing and ice making.

[0139] When the partition 110 is disposed in the inner container, multiple installation positions can be disposed in the inner container along the height direction, and the partition 110 can be detachably connected to each installation position. The refrigeration area 120 and the freezing area 130 of different sizes can be divided based on different installation positions, so that the size of the refrigeration area 120 and the freezing area 130 can be changed according to the user's own needs.
