Description

Technical Field

[0001] This utility model relates to the field of tea bar machine technology, and in particular to an ice water recirculation structure for a tea bar machine that provides purified drinking water. Background Technology

[0002] A Chinese patent with publication number CN202304170U discloses an ice-water separation device for an ice maker, including a housing, an ice-making box driven by an ice-turning motor in the inner cavity of the housing, a condenser in the ice-making box, an ice-water separation rack below the ice-making box that can bounce ice blocks that fall off the condenser to an ice storage box located below the front side of the ice-making box, and a water receiving tray below the ice-water separation rack that is connected to a water storage tank.

[0003] However, the ice-water separation device of the ice maker mentioned above has the following drawbacks: after passing through the ice-water separation rack, the device separates the water and drops it into the water receiving tray below. The ice water in the water receiving tray eventually falls into the water storage tank for reuse. However, the ice water in the water storage tank will lose its coldness and needs to be refrigerated again when used next time. This will increase the ice-making time and make the ice-making process less efficient, which urgently needs to be improved. Utility Model Content

[0004] The purpose of this invention is to provide an ice water recirculation structure for a tea purifier, which improves ice-making efficiency and prevents bacterial growth caused by water accumulation at the bottom of the return water tank.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: an ice water recirculation structure for a tea bar machine, comprising a tea bar machine body, an ice water supply device and an ice-making component disposed within the tea bar machine body, the ice-making component comprising an ice receiving frame, a water return chamber and an ice-making box, the ice water supply device being used to replenish water to the ice-making box, the ice-making box being provided with a refrigeration evaporator, the water return chamber being fixedly disposed on the tea bar machine body and located above the ice receiving frame, and the side of the water return chamber having an opening corresponding to the ice receiving frame, the ice-making box being rotatably disposed within the water return chamber, and the side of the ice-making box near the opening having an ice-tumbling plate;

[0006] It also includes a drive device that drives the ice-making box to rotate in the return water chamber. The bottom of the return water chamber is provided with a drain connector, which is connected to the ice water supply device through a return water pipe.

[0007] By adopting the above technical solution, the ice water supply device supplies pre-cooled ice water to the ice-making box. Ice cubes are prepared in the ice-making box using a refrigeration evaporator. Then, the ice is de-iced, separating the ice cubes from the refrigeration evaporator and falling back into the ice-making box. A drive device then rotates the ice-making box relative to the return water chamber, causing the ice cubes and a small amount of accumulated water in the ice-making box to fall into the return water chamber. At this point, an ice-tumbling plate stops the ice cubes from rolling to the bottom of the return water chamber. The accumulated water flows through the gap between the ice-tumbling plate and the return water chamber to the bottom of the return water chamber, and then flows back to the ice water supply device through the drain connector and return water pipe. Then, the driving device drives the ice box to reset. During the reset process, the ice cubes in the ice box are flipped from the opening position to the ice receiving frame for storage using the ice-flipping plate. This utility model uses an ice water supply device to pre-cool the water supplied to the ice box, thereby improving the ice cube preparation efficiency in the ice box. At the same time, by setting a drain connector at the bottom of the return water tank, the water in the return water tank can flow back to the ice water supply device through the drain connector and return water pipe, which can effectively prevent the water at the bottom of the return water tank from breeding bacteria. It has the effects of improving ice making efficiency and preventing the water at the bottom of the return water tank from breeding bacteria.

[0008] A further feature of this invention is that: a mounting housing is fixedly connected to the top of the ice water supply device; the mounting housing has a accommodating space for accommodating the ice receiving frame and the return water tank; the mounting housing has a pull-out hole corresponding to the ice receiving frame that communicates with the accommodating space; and the ice receiving frame is pulled out and installed in the mounting housing through the pull-out hole.

[0009] By adopting the above technical solution, the ice collection frame can be pulled out from the pull hole of the mounting shell to collect ice. At the same time, the mounting shell is installed on the top of the ice water replenishment device, which helps to shorten the distance between the return water tank and the ice water replenishment device, reduce the loss of cold energy during the process of water accumulating at the bottom of the return water tank flowing back to the ice water replenishment device, thereby achieving the purpose of saving electricity.

[0010] A further feature of this invention is that the mounting housing has a stepped hole corresponding to the drain connector, a sealing sleeve is fixed inside the stepped hole, the drain connector passes through the sealing sleeve and is inserted into the inlet end of the return water pipe, and the drain connector and the return water pipe are sealed together by the sealing sleeve.

[0011] By adopting the above technical solution, the addition of a sealing sleeve improves the water leakage prevention performance between the drain connector and the return pipe.

[0012] A further feature of this invention is that the mounting housing includes a cold-insulating part for mounting the ice-receiving frame and an extension part extending along the side of the mounting housing for accommodating the return water tank. A clearance space is formed between the bottom of the extension part and the side of the cold-insulating part above the ice water supply device, and the return water pipe is arranged within the clearance space.

[0013] By adopting the above technical solution, the layout of each component of this utility model within the main body of the tea bar machine is more reasonable. At the same time, the arrangement of the clearance space is also conducive to the installation and connection of the return water pipe, and the cold insulation part can effectively keep the ice frame cold, extending the cold insulation time of the ice frame.

[0014] A further feature of this invention is that the projection area of ​​the water return chamber in the height direction of the main body of the tea bar machine partially overlaps with the ice receiving frame.

[0015] By adopting the above technical solution, the driving device drives the ice-tumbling plate to flip the ice blocks in the ice-making box and let them fall into the ice-receiving frame.

[0016] A further feature of this invention is that the ice water supply device includes a cold tank, a water pump, and a water supply pipe. The main body of the tea bar machine is equipped with a refrigeration compression module corresponding to the cold tank. The water pump is used to pump the water in the cold tank to the ice box through the water supply pipe.

[0017] By adopting the above technical solution, the ice water produced in the cold tank can be replenished to the ice box through a water pump and a water supply pipe. The refrigeration compression module can compress the refrigerant gas circulating in the cold tank to provide power for the refrigeration cycle system.

[0018] A further feature of this invention is that: the cold tank is provided with an evaporator coil, the cold tank is provided with a return water connector for connecting to the outlet end of the return water pipe, the return water connector is located at the top of the cold tank, and the return water connector is located within the vertical projection area of ​​the evaporator coil on the main body of the tea bar machine.

[0019] By adopting the above technical solution, the return water connector is set above the evaporator coil of the cold tank, so that the water flowing back into the cold tank can directly contact the low-temperature evaporator coil for heat exchange, thereby improving the cooling rate of the water flowing back into the cold tank.

[0020] A further feature of this invention is that the cold air chamber is wrapped with an insulation cover, and the mounting housing is fixedly connected to the upper end of the insulation cover.

[0021] By adopting the above technical solution, the insulation cover can keep the cold tank cold, reduce the loss rate of the cold tank's cold energy, and fix the mounting shell to the upper end of the insulation cover to prevent the mounting shell from directly contacting the cold tank, thus preventing the cold energy of the cold tank from being lost due to direct heat transfer through the mounting shell.

[0022] A further feature of this invention is that a pressure balancing pipe is connected between the cooling liner and the mounting housing, and the cooling liner is connected to the accommodating space through the pressure balancing pipe.

[0023] By adopting the above technical solution, the air pressure balance pipe can connect the air pressure of the cold tank and the housing space, ensuring that the pressure in the cold tank is always consistent with the air pressure at the return water tank in the housing space, which is conducive to the water accumulated at the bottom of the return water tank flowing smoothly back into the cold tank through the return water pipe.

[0024] A further feature of this invention is that the pressure balancing pipe is located within the clearance space, and the air inlet of the pressure balancing pipe is connected to the top of the cooling liner, while the air outlet of the pressure balancing pipe is connected to the side wall of the insulation section and communicates with the accommodating space.

[0025] By adopting the above technical solution, the air pressure balance pipe is placed in the clearance space, which is beneficial for the installation and disassembly of the air pressure balance pipe.

[0026] In summary, this utility model has the following beneficial effects:

[0027] The tea bar machine incorporates an ice water supply device within its main body. A mounting housing is fixedly connected to the top of this device, and an ice-receiving frame and a water return chamber are housed within the housing. An ice-making box rotates within the water return chamber, and a water return pipe connects to the top of the ice water supply device at the bottom. The ice water supply device supplies pre-cooled ice water to the ice-making box, where a refrigeration evaporator prepares ice cubes. The ice cubes then detach from the evaporator and fall back into the ice-making box. A drive mechanism rotates the ice-making box relative to the water return chamber, causing the ice cubes and a small amount of accumulated water to fall into the water return chamber. An ice-turning plate prevents the ice cubes from rolling to the bottom of the water return chamber, and the accumulated water is removed through the ice-turning plate. The water flows through the gap between the plate and the return water tank to the bottom of the return water tank. Then, the accumulated water flows back to the ice water supply device through the drain connector and the return water pipe. After that, the driving device drives the ice box to reset. During the reset process, the ice-turning plate flips the ice cubes in the ice box from the opening position to the ice receiving frame for storage. This utility model uses the ice water supply device to pre-cool the water supplied to the ice box, thereby improving the ice cube preparation efficiency in the ice box. At the same time, by setting a drain connector at the bottom of the return water tank, the accumulated water in the return water tank can flow back to the ice water supply device through the drain connector and the return water pipe, which can effectively prevent the accumulation of water at the bottom of the return water tank from breeding bacteria. It has the effects of improving ice making efficiency and preventing the accumulation of water at the bottom of the return water tank from causing bacterial growth. Attached Figure Description

[0034] The present invention will be further described below with reference to the accompanying drawings.

[0035] An ice water recirculation structure for a tea purifier, such as Figures 1-5 As shown, the device includes a tea bar machine body 1, an ice water supply device 2 and an ice-making assembly located within the tea bar machine body 1. The ice-making assembly includes an ice receiving frame 4, a water return chamber 5, and an ice-making box 6. The ice water supply device 2 is used to replenish water to the ice-making box 6. The ice-making box 6 is equipped with a refrigeration evaporator 61. The water return chamber 5 is fixed on the tea bar machine body 1 and located above the ice receiving frame 4. The side of the water return chamber 5 has an opening 51 corresponding to the ice receiving frame 4. The ice-making box 6 is rotatably located within the water return chamber 5. An ice-turning plate 62 is provided on the side of the ice-making box 6 near the opening 51. A gap 621 is left between the ice-turning plate 62 and the water return chamber 5. The ice-turning plate 62 is equipped with... The machine includes several water passage holes 622; it also includes a drive device 63, which drives the ice box 6 to rotate in the return water chamber 5. The bottom of the return water chamber 5 is provided with a drain connector 52, which is connected to the ice water supply device 2 through a return water pipe 50. The main body 1 of the tea bar machine is also provided with a filter element, which is used to filter the raw water before it enters the ice chamber. In this embodiment, the bottom of the return water chamber 5 is set as an arc surface, which is conducive to the accumulation of water in the return water chamber 5. The drain connector 52 is set at the lowest point of the bottom of the return water chamber 5 to ensure that the water accumulated in the return water chamber 5 can be completely drained through the drain connector 52 and the return water pipe 50.

[0036] like Figures 2-5As shown, a mounting housing 3 is fixedly connected to the top of the ice water supply device 2. The mounting housing 3 has a receiving space 31 for accommodating the ice receiving frame 4 and the return water tank 5. The mounting housing 3 has a pull-out hole 32 corresponding to the ice receiving frame 4, which communicates with the receiving space 31. The ice receiving frame 4 is pulled out of the mounting housing 3 through the pull-out hole 32, so that the ice receiving frame 4 can be pulled out from the pull-out hole 32 of the mounting housing 3 to collect ice. At the same time, installing the mounting housing 3 on the top of the ice water supply device helps to shorten the distance between the return water tank 5 and the ice water supply device 2, and reduce the cold loss during the process of water accumulating at the bottom of the return water tank 5 flowing back to the ice water supply device 2. The mounting housing 3 has a stepped hole 33 corresponding to the drain connector 52, and a sealing sleeve 34 is fixed inside the stepped hole 33. The drain connector 52 passes through the sealing sleeve 34 and is inserted into the inlet end of the return water pipe 50. The drain connector 52 and the return water pipe 50 are sealed together by the sealing sleeve 34. The addition of the sealing sleeve 34 improves the water-proof performance between the drain connector 52 and the return water pipe 50. The mounting housing 3 includes a cold insulation part 301 for installing the ice frame 4 and an extension part 302 extending along the side of the mounting housing 3 to accommodate the return water chamber 5. The bottom of the extension part 302 is connected to the cold insulation part 301. A clearance space 35 is formed between the sides of part 301 above the ice water supply device 2. The return water pipe 50 is arranged in the clearance space 35, which makes the layout of each component of this utility model in the tea bar machine body 1 more reasonable. At the same time, the setting of the clearance space 35 is also conducive to the installation and connection of the return water pipe 50. The cold insulation part 301 can effectively keep the ice frame 4 cold, extending the cold insulation time of the ice frame 4. The projection area of ​​the return water tank 5 in the height direction of the tea bar machine body 1 partially overlaps with the ice frame 4, so that the drive device 63 drives the ice-turning plate 62 to turn the ice in the ice box 6 down and fall into the ice frame 4. The ice water supply device 2 includes a cold tank 21, a water pump 23, and a water supply pipe 24. The main body 1 of the tea bar machine is equipped with a refrigeration compression module 7 corresponding to the cold tank 21. The water pump 23 is used to pump the water in the cold tank 21 to the ice box 6 through the water supply pipe 24. The ice water produced in the cold tank 21 can be replenished to the ice box 6 through the water pump 23 and the water supply pipe 24. The refrigeration compression module 7 can compress the refrigerant gas circulating in the cold tank 21 to provide power for the refrigeration cycle system. In addition, in this embodiment, the bottom of the mounting housing 3 is provided with a drain pipe 36. The upper end of the drain pipe 36 is connected to the accommodating space 31, and the lower end of the drain pipe 36 is connected to the cold tank 21.

[0037] like Figures 2-4As shown, the cold tank 21 is equipped with an evaporator coil 212. The cold tank 21 also has a return water connector 210 for connecting to the outlet of the return water pipe 50. The return water connector 210 is located at the top of the cold tank 21, and is situated within the vertical projection area of ​​the evaporator coil 212 on the main body 1 of the tea bar machine. Positioning the return water connector 210 above the evaporator coil 212 in the cold tank 21 allows the water flowing back from the return water pipe 50 into the cold tank 21 to directly contact the low-temperature evaporator coil 212 for heat exchange, thus increasing the cooling rate of the water flowing back from the return water chamber 5 to the cold tank 21. The cold tank 21 is encased in an insulation cover 22. A mounting shell 3 is fixedly connected to the upper end of the insulation cover 22. The insulation cover 22 keeps the cold tank 21 cool, reducing the loss of cooling capacity. Fixing the mounting shell 3 to the upper end of the insulation cover 22 also prevents direct contact between the mounting shell 3 and the cold tank 21. The direct contact causes a loss of cooling capacity in the cooling tank 21 due to heat transfer through the mounting housing 3. A pressure balancing pipe 211 connects the cooling tank 21 to the mounting housing 3, and the cooling tank 21 is connected to the accommodating space 31 through the pressure balancing pipe 211. The pressure balancing pipe 211 connects the air pressure of the cooling tank 21 to the accommodating space 31, ensuring that the pressure in the cooling tank 21 is always consistent with the air pressure at the return water chamber 5 in the accommodating space 31. This facilitates the smooth flow of water accumulated at the bottom of the return water chamber 5 back to the cooling tank 21 through the return water pipe 50. The pressure balancing pipe 211 is located in the clearance space 35, with its air inlet connected to the top of the cooling tank 21 and its air outlet connected to the side wall of the insulation part 301 and connected to the accommodating space 31. The placement of the pressure balancing pipe 211 in the clearance space 35 facilitates its installation and removal.

[0038] The basic working principle of this utility model is as follows: An ice water supply device 2 is installed inside the main body 1 of the tea bar machine. A mounting shell 3 is fixedly connected to the top of the ice water supply device 2. An ice receiving frame 4 and a water return chamber 5 are installed within the accommodating space 31 of the mounting shell 3. An ice-making box 6 is rotatably installed inside the water return chamber 5. A water return pipe 50 is installed at the bottom of the water return chamber 5 and connects to the top of the ice water supply device 2. The ice water supply device 2 supplies pre-cooled ice water to the ice-making box 6. Ice cubes are prepared in the ice-making box 6 using a refrigeration evaporator 61. Then, the ice is removed. This removal can be done manually or using existing micro-heating technology to melt the ice surface in contact with the refrigeration evaporator 61, thus separating the ice cubes from the refrigeration evaporator 61. The ice cubes fall into the ice-making box 6. Then, a driving device 63 rotates the ice-making box 6 relative to the water return chamber 5, causing the ice cubes and a small amount of accumulated water in the ice-making box 6 to fall into the water return chamber 5. The ice-tumbling plate 62 stops the ice blocks from rolling to the bottom of the return water tank 5. The accumulated water flows to the bottom of the return water tank 5 through the gap 621 between the ice-tumbling plate 62 and the return water tank 5. Then, the accumulated water flows back to the ice water supply device 2 through the drain connector 52 and the return water pipe 50. After that, the driving device 63 drives the ice box 6 to reset. During the reset process, the ice-tumbling plate 62 flips the ice blocks in the ice box 6 from the opening 51 to the ice receiving frame 4 for storage. This utility model uses the ice water supply device 2 to pre-cool the water supplied to the ice box 6, thereby improving the ice block preparation efficiency in the ice box 6. At the same time, by setting the drain connector 52 at the bottom of the return water tank 5, the accumulated water in the return water tank 5 flows back to the ice water supply device 2 through the drain connector 52 and the return water pipe 50, which can effectively prevent the accumulation of water at the bottom of the return water tank 5 from breeding bacteria. It has the effects of improving ice making efficiency and preventing the accumulation of water at the bottom of the return water tank from causing bacterial growth.

[0039] The above description is only a preferred embodiment of the present utility model. Therefore, all equivalent changes or modifications made to the structure, features and principles described in the claims of the present utility model patent application are included in the scope of the present utility model patent application.
