Description

Technical Field

[0001] This utility model relates to the field of bullet ice making machine technology, specifically to a vacuum water pumping ice making machine. Background Technology

[0002] The existing bullet ice maker's water system mainly consists of a water tank, an ice-making water tank, an ice-making box, water pipes, and a water pump. The water tank, ice-making water tank, ice-making box, water pipes, and water pump are fixedly connected and located inside the main unit. Water is supplied through the operation of the water pump. This structure results in the ice-making water tank and the water tank being fixed and cannot be disassembled, which leads to the problem of inconvenience in cleaning the ice-making water tank and the water tank.

[0003] For example, utility model patent CN103900313A discloses a small ice maker, including a main body, a casing, a control board, a water supply device, an ice-making and ice-removing device, and an ice-scraping device. The water supply device, ice-making and ice-removing device, and ice-scraping device are all fixed inside the main body, and the control board is fixed inside the casing. The water supply device includes a water tank, an ice-making water tank with rotating shafts at both ends, a water pipe, and a water pump that can lead water from the water tank to the ice-making water tank through the water pipe. In this prior art, the ice-making water tank is fixedly connected to the water tank and the ice-making container via the water pipe and water pump. This means that the ice-making water tank and the water tank cannot be disassembled for cleaning, especially since sugary solutions (such as beverages) cannot be added to make ice. Otherwise, due to the difficulty in cleaning, odors and bacteria will remain in the ice-making water tank, water tank, water pipe, and water pump, thus affecting the user's use and health.

[0004] Therefore, existing technologies still need to be improved and developed. Utility Model Content

[0005] To address the problems of existing technologies, this utility model provides a vacuum water pumping ice maker. It utilizes an air pump assembly to vacuum-pump the water storage chamber and pressurize it with air to transport liquid from the water tank to the storage chamber, and then to the ice-making box. There are no fixed connections between the ice-making box, water tank, and pumping tank assembly. After ice making, the water tank and pumping tank assembly can be easily disassembled and cleaned. This allows the ice maker to be used with sugary solutions (such as beverages) without concerns about insufficient cleaning affecting user experience and health.

[0006] To achieve the above objectives, the technical solution applied in this utility model is as follows:

[0007] A vacuum water pumping ice maker includes a main unit with a cavity formed therein. A hinged flap for opening or closing the cavity is attached to the opening of the cavity. An ice-making box and a refrigeration component are fixed in the cavity. A water tank is detachably installed in the cavity. A water pumping assembly is detachably installed in the cavity and has a water storage chamber formed therein. The water pumping assembly has an inlet and an outlet, with the inlet corresponding to the water tank and the outlet corresponding to the ice-making box. An air pump assembly is fixed in the cavity and is corresponding to the water storage chamber. When the air pump assembly draws air into the water storage chamber to create negative pressure, liquid in the water tank can be drawn into the water storage chamber. When the air pump assembly pressurizes the water storage chamber, liquid in the water storage chamber can be discharged into the ice-making box. With this design, during operation, the air pump assembly evacuates the water storage chamber, drawing liquid from the water tank into it. Then, the air pump assembly inflates the water storage chamber, discharging the liquid into the ice maker. This vacuum pumping and pressurization process transfers the liquid from the water tank to the storage chamber and then to the ice maker. Since there are no fixed water pipes or pumps connecting the ice maker, water tank, and pump assembly, the water tank and pump assembly can be easily disassembled and cleaned after ice making. This allows the ice maker to be used with sugary solutions (such as beverages) without worrying about insufficient cleaning affecting user experience or health.

[0008] According to the above scheme, the water tank assembly includes a water tank and a tank cover. The tank cover is detachably installed on the water tank. The water tank is provided with a water inlet, a water outlet, an air extraction hole, and an air inflation hole. When the water tank assembly is installed in the accommodating cavity, the water inlet is located above the water tank, and a water extraction pipe is fixed on the water inlet. The lower end of the water extraction pipe extends into the water tank. The water outlet is located above the ice maker. The air extraction hole and the air inflation hole are respectively connected to the air pump assembly. Two clearance grooves are formed on the inner wall of the tank cover for cooperating with the air extraction hole and the air inflation hole. With this configuration, when the water tank assembly is installed in the accommodating cavity, the air extraction port and the air inflation port are respectively connected to the air pump assembly, thus connecting the air passage between the water tank assembly and the air pump assembly to enable the air pump assembly to extract or inflate the water storage cavity. The water inlet extends into the water tank through a water extraction pipe, which can extract water without fixed connection. The water outlet is located above the ice maker, which can directly discharge water into the ice maker without water pipe connection. Two clearance grooves are provided on the inner wall of the lid to cooperate with the openings at the upper ends of the air extraction port and the air inflation port located in the water storage cavity. That is, after assembly, the openings at the upper ends of the air extraction port and the air inflation port are located in the clearance grooves on the lid. This allows the air extraction port and the air inflation port to communicate with the water storage cavity to realize the air extraction or inflation function, while preventing liquid in the water storage cavity from entering the air extraction port and the air inflation port.

[0009] According to the above scheme, a sealing ring is provided between the tank cover and the water tank. This arrangement creates a closed space inside the water storage chamber when the tank cover is closed on the water tank, facilitating the air pump assembly to create a vacuum and generate negative pressure.

[0010] According to the above scheme, a hollow sleeve is fixed inside the water inlet, and a water inlet duckbill valve is fixed at the upper end of the hollow sleeve. The water inlet duckbill valve is located in the water storage chamber, and a water suction pipe is fixed at the lower end of the hollow sleeve. This configuration, with the water inlet duckbill valve fixed at the upper end of the hollow sleeve and located in the water storage chamber, ensures that the water inlet duckbill valve is initially closed. It only opens when a vacuum is created in the water storage chamber to form a negative pressure, making it convenient to use.

[0011] According to the above scheme, a duckbill valve is fixed on the water outlet, and the duckbill valve is located outside the water tank. With this configuration, the duckbill valve is in the closed state when pumping water, and only opens when the water storage chamber is pressurized by air, making it convenient to use.

[0012] According to the above scheme, the air pump assembly includes an air pump, a suction pipe, and an inflation pipe. One end of the suction pipe is connected to the air pump inlet, and the other end is fixed with a suction solenoid valve, which is correspondingly set with the suction port. One end of the inflation pipe is connected to the air pump outlet, and the other end is fixed with an inflation solenoid valve, which is correspondingly set with the inflation port. With this configuration, by fixing the suction solenoid valve on the suction pipe corresponding to the suction port and the inflation solenoid valve on the inflation pipe corresponding to the inflation port, the water storage chamber can be switched between vacuuming and inflation by controlling whether the suction and inflation solenoid valves are energized or de-energized.

[0013] According to the above scheme, the suction solenoid valve is provided with interface 1, interface 2 and interface 3. Interface 1 is connected to the suction pipe, interface 2 is connected to the accommodating cavity, and interface 3 is correspondingly set to the suction port. When the suction solenoid valve is not energized, interface 1 and interface 3 are connected. When the suction solenoid valve is energized, interface 1 and interface 2 are connected. The inflation solenoid valve is provided with interface 4, interface 5 and interface 6. Interface 4 is connected to the inflation pipe, interface 5 is connected to the accommodating cavity, and interface 6 is correspondingly set to the inflation port. When the inflation solenoid valve is not energized, interface 4 and interface 6 are connected. When the inflation solenoid valve is energized, interface 4 and interface 5 are connected. With this setup, during ice making, the air pump and the inflation solenoid valve are energized. After the inflation solenoid valve is energized, ports four and five are connected. The suction solenoid valve is not energized, and ports one and three are connected. Air inside the water tank enters the air pump through port three of the suction solenoid valve and the suction pipe, and then exits into the accommodating cavity through the inflation pipe and port five of the inflation solenoid valve, creating negative pressure inside the water tank. The inlet valve opens and draws liquid from the water tank into the water tank through the suction pipe. When the water level reaches a certain position (the position of the conductive needle), the inflation solenoid valve is de-energized, ports four and six are connected, the air pump and the suction solenoid valve are energized, and ports one and two are connected. The air pump draws air from port two of the suction solenoid valve and then fills the water tank with air. The air pressure inside the water tank increases, causing the outlet valve to open and drain the liquid from the water tank into the ice maker to begin ice making.

[0014] According to the above scheme, interfaces three and six are respectively protruding from the main unit. Interface three is fixed with a suction plug that seals with the suction port, and interface six is ​​fixed with an inflation plug that seals with the inflation port. With interfaces three and six protruding from the main unit, after the water tank assembly is assembled, the suction port and inflation port of the water tank connect with interfaces three and six respectively, where the suction plug and inflation plug provide a sealing effect at the connection point.

[0015] According to the above scheme, a water level assembly is installed on the water tank. The water level assembly includes a conductive needle fixing block and two conductive needles. The two conductive needles are fixed to the water tank by the conductive needle fixing block and are located between the conductive needle fixing block and the water tank. The water tank has two sleeve holes I formed on it, and the conductive needle fixing block has two sleeve holes II formed on it and a groove. The upper ends of the two conductive needles pass through the two sleeve holes I respectively and are located in the water storage cavity. The upper ends of the conductive needles are fixed with sealing plugs that cooperate with the sleeve holes I to seal. The lower ends of the two conductive needles pass through the two sleeve holes II respectively and are located in the groove. The main unit is provided with a conductive component that cooperates with the conductive needles to realize circuit conduction, and the conductive component is electrically connected to the air pump assembly. With this setup, when the water volume reaches the position of the conductive needle in the water storage chamber, the two conductive needles connect. At this time, the air pump stops its vacuum function and switches to its inflation function, draining the liquid in the water tank into the ice maker to start making ice. The sealing plug serves to prevent leakage. The lower ends of the two conductive needles pass through the two sleeve holes and are located in the groove, forming a coupling female interface that cooperates with the conductive components.

[0016] According to the above scheme, the conductive component includes a convex shroud and a conductive pin connecting plate. The convex shroud is fixedly protruding from the main unit, and the convex shroud and the groove are correspondingly arranged. The conductive pin connecting plate is fixed on the convex shroud, and two spring pins are fixed on the conductive pin connecting plate. Two sleeve holes are formed on the convex shroud. The upper ends of the two spring pins pass through the two sleeve holes respectively to cooperate with the two conductive pins to achieve circuit conduction. The conductive pin connecting plate is electrically connected to the air pump assembly. With this configuration, when the water tank assembly is assembled, the groove on the conductive pin fixing block cooperates with the convex shroud to make the spring pins and conductive pins communicate; wherein the convex shroud is fixedly protruding from the main unit, and the upper ends of the spring pins pass through the two sleeve holes respectively to form coupling male interfaces that cooperate with and couple with the two conductive pins.

[0017] The beneficial effects of this utility model are:

[0018] This invention utilizes an air pump assembly to vacuum-pump the water storage chamber and pressurize it with air to transport the liquid from the water tank to the storage chamber, and then to the ice maker. There are no fixed connections between the ice maker, water tank, and pump assembly via water pipes or pumps. After ice making, the water tank and pump assembly can be easily disassembled and cleaned, allowing the ice maker to be used with sugary solutions (such as beverages) without worrying about insufficient cleaning affecting user experience and health.

[0031] The technical solution of this utility model will be described below with reference to the accompanying drawings and embodiments.

[0032] like Figures 1 to 8As shown, the vacuum water pumping ice maker of this utility model includes a main unit 4, which has a cavity formed inside. A flip cover 3 for opening or closing the cavity is hinged to the opening of the cavity. An ice maker 5 and a refrigeration component are fixed in the cavity. A water tank 6 is detachably installed in the cavity. A water pumping tank assembly 1 is detachably installed in the cavity and has a water storage chamber formed inside. The water pumping tank assembly 1 has an inlet and an outlet, with the inlet corresponding to the water tank 6 and the outlet corresponding to the ice maker 5. An air pump assembly 2 is fixed in the cavity and is corresponding to the water storage chamber. When the air pump assembly 2 pumps air into the water storage chamber to create negative pressure, it can pump the liquid in the water tank 6 into the water storage chamber. When the air pump assembly 2 pressurizes the water storage chamber, it can discharge the liquid in the water storage chamber into the ice maker 5. With this configuration, during operation, the air pump assembly 2 draws air into the water storage chamber, drawing the liquid from the water tank 6 into the storage chamber. Then, the air pump assembly 2 inflates the storage chamber, discharging the liquid into the ice maker 5. The air pump assembly 2 uses vacuum pumping and pressurization to transport the liquid from the water tank 6 to the storage chamber and then to the ice maker 5. There are no water pipes or pumps fixedly connected between the ice maker 5, the water tank 6, and the water pump assembly 1. After ice making, the water tank 6 and the water pump assembly 1 can be easily disassembled and cleaned. This allows the ice maker to add sugary solutions (such as beverages) to make ice without worrying about insufficient cleaning affecting the user's use and health.

[0033] The flip cover 3 can be used to open or close the accommodating cavity, making it convenient to install and remove the water tank 6 and the water pumping tank assembly 1, and the accommodating cavity also serves as a dustproof feature.

[0034] In practical applications, the refrigeration assembly includes a condenser 7 and a compressor 8. The ice maker 5, the condenser 7, and the compressor 8 are connected by pipelines to provide refrigerant to the ice maker 5. This structure is existing technology and will not be described in detail.

[0035] Furthermore, the water tank assembly 1 includes a water tank 11 and a cover 12. The cover 12 is detachably installed on the water tank 11. The water tank 11 is provided with a water inlet, a water outlet, an air extraction hole 14, and an air inflation hole 15. When the water tank assembly 1 is installed in the accommodating cavity, the water inlet is located above the water tank 6, and a water extraction pipe 18 is fixed on the water inlet. The lower end of the water extraction pipe 18 extends into the water tank 6. The water outlet is located above the ice maker 5. The air extraction hole 14 and the air inflation hole 15 are respectively connected to the air pump assembly 2. Two clearance grooves 116 are formed on the inner wall of the cover 12 for cooperating with the air extraction hole 14 and the air inflation hole 15. With this configuration, when the water tank assembly 1 is installed in the accommodating cavity, the air extraction port 14 and the air inflation port 15 are respectively connected to the air pump assembly 2, thus connecting the water tank assembly 1 and the air pump assembly 2 via an air passage, enabling the air pump assembly 2 to extract or inflate the water storage cavity. The water inlet extends into the water tank 6 via the water extraction pipe 18, requiring no fixed connection for water extraction. The water outlet is located above the ice maker 5, requiring no water pipe connection, allowing water to flow directly into the ice maker 5. The inner wall of the cover 12 has two clearance grooves 116 for engaging with the openings at the upper ends of the air extraction hole 14 and the air filling hole 15 located in the water storage cavity. That is, after assembly, the openings at the upper ends of the air extraction hole 14 and the air filling hole 15 are located in the clearance grooves 116 on the cover 12. This allows the air extraction hole 14 and the air filling hole 15 to communicate with the water storage cavity to achieve the function of air extraction or air filling, while preventing liquid in the water storage cavity from entering the air extraction hole 14 and the air filling hole 15.

[0036] Furthermore, a sealing ring 13 is provided between the cover 12 and the water tank 11. This arrangement creates a closed space inside the water storage chamber when the cover 12 is closed on the water tank 11, facilitating the air pump assembly 2 to create a vacuum and generate negative pressure.

[0037] Furthermore, a hollow sleeve 113 is fixed inside the water inlet, and a water inlet duckbill valve 16 is fixed to the upper end of the hollow sleeve 113. The water inlet duckbill valve 16 is located in the water storage chamber, and a water suction pipe 18 is fixed to the lower end of the hollow sleeve 113. This configuration, with the water inlet duckbill valve 16 fixed to the upper end of the hollow sleeve 113 and located in the water storage chamber, ensures that the water inlet duckbill valve 16 is initially closed. It only opens when a vacuum is created in the water storage chamber to form a negative pressure, making it convenient to use.

[0038] Furthermore, a water outlet valve 17 is fixed on the water outlet, and the water outlet valve 17 is located outside the water tank 11. With this configuration, the water outlet valve 17 is in the closed state when pumping water, and only when the water storage chamber is pressurized by air, the water outlet valve 17 is in the open state, which is convenient to use.

[0039] Furthermore, the air pump assembly 2 includes an air pump 21, an air extraction pipe 22, and an air filling pipe 25. One end of the air extraction pipe 22 is connected to the air inlet of the air pump 21, and the other end of the air extraction pipe 22 is fixed with an air extraction solenoid valve 23, which is correspondingly arranged with the air extraction port 14. One end of the air filling pipe 25 is connected to the air outlet of the air pump 21, and the other end of the air filling pipe 25 is fixed with an air filling solenoid valve 26, which is correspondingly arranged with the air filling port 15. With this configuration, by fixing the air extraction solenoid valve 23 on the air extraction pipe 22 and the air filling solenoid valve 26 on the air filling pipe 25 and the air filling solenoid valve 26 and the air extraction solenoid valve 23 and the air filling solenoid valve 26 to be energized or de-energized, the water storage chamber can be switched between vacuuming and filling.

[0040] Furthermore, the suction solenoid valve 23 is provided with interface 1 211, interface 212, and interface 3 213. Interface 1 211 is connected to the suction pipe 22, interface 212 is connected to the accommodating cavity, and interface 3 213 is correspondingly set with the suction port 14. When the suction solenoid valve 23 is not energized, interface 1 211 and interface 3 213 are connected. When the suction solenoid valve 23 is energized, interface 1 211 and interface 2 212 are connected. The inflation solenoid valve 26 is provided with interface 4 214, interface 5 215, and interface 6 216. Interface 4 214 is connected to the inflation pipe 25, interface 5 215 is connected to the accommodating cavity, and interface 6 216 is correspondingly set with the inflation port 15. When the inflation solenoid valve 26 is not energized, interface 4 214 and interface 6 216 are connected. When the inflation solenoid valve 26 is energized, interface 4 214 and interface 5 215 are connected. With this setup, during ice making, the air pump 21 and the inflation solenoid valve 26 are energized. After the inflation solenoid valve 26 is energized, interface 4 214 and interface 5 215 are connected. The suction solenoid valve 23 is not energized, and interface 1 211 and interface 3 213 are connected. Air inside the water tank 11 enters the air pump 21 through interface 3 213 of the suction solenoid valve 23 and the suction pipe 22, and is then discharged into the receiving cavity through the inflation pipe 25 and interface 5 215 of the inflation solenoid valve 26, creating a negative pressure inside the water tank 11. This causes the water inlet duckbill valve 16 to open and draw water from the water tank 6. Liquid is pumped into the water tank 11 through the pumping pipe 18. When the water level reaches a certain position (the position of the conductive needle 19), the inflation solenoid valve 26 is de-energized, and the interfaces 4 214 and 6 216 are connected. The air pump 21 and the suction solenoid valve 23 are energized, and the interfaces 1 211 and 2 212 are connected. The air pump 21 draws air from the interface 2 212 of the suction solenoid valve 23 and then pumps the air into the water tank 11. The air pressure in the water tank 11 increases, causing the water outlet duckbill valve 17 to open and discharge the liquid in the water tank 11 into the ice maker 5 to start making ice.

[0041] In practical applications, the vacuum solenoid valve 23 and the inflation solenoid valve 26 have the same structure, both being two-position three-way solenoid valves.

[0042] Furthermore, interfaces 3 (213) and 6 (216) are respectively protruding from the main unit 4. Interface 3 (213) is fixed with a suction plug 24 that seals against the suction port 14, and interface 6 (216) is fixed with an inflation plug 27 that seals against the inflation port 15. This arrangement, with interfaces 3 (213) and 6 (216) protruding from the main unit 4, ensures that after the water tank assembly 1 is assembled, the suction port 14 and inflation port 1 of the water tank 11 are connected to interfaces 3 (213) and 6 (216) respectively. The suction plug 24 and inflation plug 27 provide a sealing effect at the connection points.

[0043] Furthermore, a water level assembly is installed on the water tank 11. The water level assembly includes a conductive needle fixing block 111 and two conductive needles 19. The two conductive needles 19 are fixed to the water tank 11 by the conductive needle fixing block 111 and are located between the conductive needle fixing block 111 and the water tank 11. The water tank 11 has two sleeve holes 114 formed on it. The conductive needle fixing block 111 has two sleeve holes 115 and a groove 112 formed on it. The upper ends of the two conductive needles 19 pass through the two sleeve holes 114 and are located in the water storage cavity. The upper ends of the conductive needles 19 are fixed with sealing plugs 110 that cooperate with the sleeve holes 114 to seal. The lower ends of the two conductive needles 19 pass through the two sleeve holes 115 and are located in the groove 112. The main unit 4 is provided with a conductive component that cooperates with the conductive needles 19 to achieve circuit conduction. The conductive component is electrically connected to the air pump assembly 2. With this configuration, when the water volume reaches the position of the conductive needle 19 in the water storage chamber, the two conductive needles 19 are connected. At this time, the air pump 21 stops the vacuum function and switches to the air filling function, draining the liquid in the water tank 11 into the ice box 5 to start ice making. The sealing plug 110 plays a role in sealing and preventing leakage. The lower ends of the two conductive needles 19 pass through the two sleeve holes 115 and are located in the groove 112, forming a coupling female interface that cooperates with the conductive component.

[0044] Furthermore, the conductive component includes a protrusion 41 and a conductive pin connecting plate 28. The protrusion 41 is fixedly protruding from the main unit 4, and the protrusion 41 is correspondingly arranged with the groove 112. The conductive pin connecting plate 28 is fixed on the protrusion 41, and two spring pins 29 are fixed on the conductive pin connecting plate 28. Two sleeve holes 42 are formed on the protrusion 41. The upper ends of the two spring pins 29 pass through the two sleeve holes 42 respectively and are used to cooperate with the two conductive pins 19 to achieve circuit conduction. The conductive pin connecting plate 28 is electrically connected to the air pump assembly 2. With this configuration, when the water tank assembly 1 is assembled, the groove 112 on the conductive pin fixing block 111 cooperates with the protrusion 41 to make the spring pins 29 and the conductive pins 19 connected; wherein the protrusion 41 is fixedly protruding from the main unit 4, and the upper ends of the spring pins 29 pass through the two sleeve holes 42 respectively to form coupling male interfaces that cooperate with the two conductive pins 19.

[0045] It should be noted that after the water tank assembly 1 is assembled, the water inlet on the water tank 11 extends into the water tank 6 through the water pipe 18 to achieve water circuit connection, without the need for water pipes and water pumps; the air extraction port 14 on the water tank 11 is inserted into interface 21 on the air extraction solenoid valve 23 of the air extraction pipe 22, and the air inflation port 15 is inserted into interface 216 on the air inflation solenoid valve 26 of the air inflation pipe 25 to achieve air circuit connection; the conductive pin fixing block 111 on the water tank 11 is coupled to the protrusion 41 to achieve circuit connection; when disassembling the water tank assembly 1, it can be directly pulled out by opening the flip cover 3, and then the water tank 6 can be taken out, which is convenient for disassembly; when assembling after cleaning, the water tank 6 is assembled first, and then the water tank assembly 1 is assembled, with corresponding insertions at each position, which is convenient for assembly.
