Description

Technical Field

[0001] The utility model belongs to the technical field of drinking water equipment, and specifically provides a water bladder device and a drinking machine. Background Art

[0002] Commonly used water dispensers generally heat water through electric heating wires and cool water through semiconductor refrigerators. However, their efficiency is low. For this reason, some water dispensers are equipped with heat pump systems and water systems at the same time, so that the heat pump system can heat and cool the water in the water system.

[0003] Among them, the water system usually has a cold water tank for storing cold water and a hot water tank for storing hot water. The heat pump system mainly includes a compressor, a condenser, a throttling and pressure reduction component and an evaporator that are connected end to end in sequence to form a loop. The condenser in the heat pump system is thermally connected to the hot water tank to heat the water in the hot water tank by the heat of the condenser. The evaporator in the heat pump system is thermally connected to the cold water tank to cool the water in the cold water tank by the coldness of the evaporator. Since the heat pump system essentially transfers part of the heat in the cold water tank to the hot water tank, the water dispenser with a heat pump system can greatly save electricity compared to traditional water dispensers.

[0004] However, when the heat pump system is working, the evaporator will condense the moisture in the air into liquid water, which will adhere to the surface of the evaporator to form condensation. Over time, the evaporator is prone to corrosion due to condensation, affecting the use effect and service life of the water dispenser. Utility Model Content

[0005] One purpose of the utility model is to solve the problem that the evaporator in the existing water dispenser with a heat pump system is easily corroded by condensation.

[0006] To achieve the above-mentioned object, the utility model provides a water tank device in a first aspect, which is applicable to a water dispenser, comprising:

[0007] The gallbladder is used to hold water;

[0008] A microchannel heat exchanger is arranged on the outside of the bile body and is thermally connected to the bile body, so that the microchannel heat exchanger heats or cools the bile body;

[0010] Optionally, a plurality of fins are arranged on the outer side of the tank body; a plurality of slots adapted to the fins are arranged on the microchannel heat exchanger so that the fins can be embedded in the slots, thereby increasing the heat exchange area between the microchannel heat exchanger and the tank body.

[0013] Optionally, the middle portion of the bottom wall of the bladder body protrudes toward the inside of the bladder body, so that an annular cavity is formed at the bottom of the bladder body, so that the microchannel heat exchanger can quickly heat or cool the water in the annular cavity.

[0014] Optionally, the water bladder device further comprises a water inlet pipe and a water outlet pipe mounted on or integrally formed with the bladder body, and a water inlet end of the water outlet pipe is located at the bottom of the annular cavity.

[0015] Optionally, the water inlet pipe and / or the water outlet pipe are fixedly connected to the top wall of the bile body or are made in one piece.

[0016] Optionally, the encapsulation shell is a foaming layer or a waterproof film formed on the outside of the body and the microchannel heat exchanger; and / or, the body is used to contain cold water, and the microchannel heat exchanger is an evaporator.

[0017] The utility model provides a water dispenser in a second aspect, comprising:

[0018] The water bladder device according to any one of the first aspects

[0019] A heat pump system, comprising a compressor, a condenser, a throttling and pressure-reducing component and the microchannel heat exchanger which are connected end to end in sequence to form a loop;

[0020] The water system comprises a reversing valve, a tank body connected to the reversing valve, and a water tank connected to the reversing valve.

[0021] Optionally, the water container is thermally connected to the condenser; and / or, the water system further includes a filter connected in series upstream of the reversing valve.

[0022] Based on the foregoing description, those skilled in the art can understand that, in the aforementioned technical solution of the utility model, the encapsulation shell encapsulates at least a portion of the body and the microchannel heat exchanger, thereby reducing or eliminating the contact between the microchannel heat exchanger and the air, thereby reducing or eliminating the condensation on the microchannel heat exchanger, and further reducing or eliminating the corrosion of the microchannel heat exchanger by condensation. Therefore, the utility model increases the service life of the microchannel heat exchanger and ensures the use effect of the water dispenser using the microchannel heat exchanger.

[0023] Furthermore, by arranging fins on the gallbladder body, arranging a plurality of slots matching the fins on the microchannel heat exchanger, and embedding the fins in the slots, not only the heat exchange area between the microchannel heat exchanger and the gallbladder body is increased, and the heat exchange efficiency between the microchannel heat exchanger and the gallbladder body is improved; but also the microchannel heat exchanger and the gallbladder body can be connected together through the fins and the slots, thereby improving the connection strength between the microchannel heat exchanger and the gallbladder body.

[0024] Furthermore, by forming an annular cavity at the bottom of the gallbladder body, the microchannel heat exchanger can quickly heat or cool the water in the annular cavity, especially when there is less water in the gallbladder body.

[0025] Furthermore, by locating the water inlet end of the water outlet pipe at the bottom of the annular cavity, the water in the bile body can be discharged as much as possible through the water outlet pipe.

[0026] Furthermore, by setting the packaging shell as a foaming layer formed on the outside of the tank body and the microchannel heat exchanger, the packaging shell can also play a role in insulating the microchannel heat exchanger, reducing the waste of cold or heat of the microchannel heat exchanger and improving the utilization rate of cold or heat of the microchannel heat exchanger.

[0033] It should be understood by those skilled in the art that the embodiments described below are only a part of the embodiments of the present invention, rather than all the embodiments of the present invention, and the embodiments are intended to explain the technical principles of the present invention, rather than to limit the protection scope of the present invention. Based on the embodiments provided by the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should still fall within the protection scope of the present invention.

[0034] It should be noted that in the description of the present invention, the terms "center", "upper", "lower", "top", "bottom", "left", "right", "vertical", "horizontal", "inside", "outside" and the like indicating directions or positional relationships are based on the directions or positional relationships shown in the drawings, which are only for the convenience of description, and do not indicate or imply that the device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention. In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0037] Refer to the following Figures 1 to 3 The water bladder device 100 of the present invention is described by way of example. Figure 1It is a structural exploded view of the water bladder device 100 in some embodiments of the utility model. Figure 2 yes Figure 1 Axonometric view of the water bladder device 100, Figure 3 yes Figure 2 A cross-sectional view of the water bladder device 100 along the AA direction.

[0038] It should be noted that the water tank device 100 of the present invention can be applied to the water dispenser 001 (such as Figure 4 It can also be applied to any other feasible water treatment equipment, such as water filter, water purifier, etc.

[0039] like Figures 1 to 3 As shown, in some embodiments of the present invention, the water bladder device 100 includes a bladder body 110 , a microchannel heat exchanger 120 and a packaging shell 130 .

[0040] The body 110 is used to contain water.

[0041] The microchannel heat exchanger 120 is disposed on the outside of the bile body 110 and is thermally connected to the bile body 110 , so that the microchannel heat exchanger 120 heats or cools the bile body 110 .

[0042] The packaging shell 130 is used to package the body 110 and at least a portion of the microchannel heat exchanger 120 .

[0043] When the tank body 110 is used to contain cold water, the microchannel heat exchanger 120 is an evaporator to cool the water in the tank body 110 through the refrigerant in the microchannel heat exchanger 120 .

[0044] When the tank body 110 is used to contain hot water, the microchannel heat exchanger 120 is a condenser 220 to heat the water in the tank body 110 through the refrigerant in the microchannel heat exchanger 120 .

[0045] It is understood by those skilled in the art that by encapsulating at least a portion of the body 110 and the microchannel heat exchanger 120 with the encapsulation shell 130, the contact between the microchannel heat exchanger 120 and the air is reduced or eliminated, thereby reducing or eliminating the condensation on the microchannel heat exchanger 120, and further reducing or eliminating the corrosion of the microchannel heat exchanger 120 by condensation. Therefore, the utility model improves the service life of the microchannel heat exchanger 120 and ensures the use effect of the water dispenser 001 using the microchannel heat exchanger 120.

[0046] like Figure 1 and Figure 3 As shown, a plurality of fins 111 are provided on the outer side of the gallbladder body 110 .

[0047] Correspondingly, a plurality of slots 121 adapted to the fins 111 are provided on the microchannel heat exchanger 120 , so that the fins 111 are embedded in the slots 121 , thereby increasing the heat exchange area between the microchannel heat exchanger 120 and the body 110 .

[0048] It will be understood by those skilled in the art that, by providing fins 111 on the gallbladder body 110, providing a plurality of slots 121 matched with the fins 111 on the microchannel heat exchanger 120, and embedding the fins 111 in the slots 121, not only the heat exchange area between the microchannel heat exchanger 120 and the gallbladder body 110 is increased, and the heat exchange efficiency between the microchannel heat exchanger 120 and the gallbladder body 110 is improved; but also the microchannel heat exchanger 120 and the gallbladder body 110 can be connected together through the fins 111 and the slots 121, thereby improving the connection strength between the microchannel heat exchanger 120 and the gallbladder body 110.

[0049] Furthermore, in some embodiments of the present invention, the body 110 is made of a material with good heat transfer performance, such as iron, stainless steel, aluminum alloy, etc.

[0050] from Figures 1 to 3 It can be seen that in some embodiments of the present invention, the body 110 is a columnar structure as a whole, and the fins 111 are arranged on the circumferential wall of the body 110. In addition, the microchannel heat exchanger 120 is wrapped around the outer side of the circumferential wall of the body 110.

[0051] from Figure 1 It can be seen that in some embodiments of the present invention, the fin 111 is approximately annular in shape as a whole. When the microchannel heat exchanger 120 is unfolded, the slot 121 is approximately strip-shaped.

[0052] Furthermore, in order to facilitate the installation and connection between the microchannel heat exchanger 120 and the bladder body 110, the microchannel heat exchanger 120 has a certain degree of flexibility as a whole, so that the staff can clip the flattened heat exchanger 120 into the fins 111 and bend it into Figure 1 The form shown.

[0053] Those skilled in the art will appreciate that the above-mentioned arrangement of the liner body 110 and the microchannel heat exchanger 120 can facilitate the assembly between the liner body 110 and the microchannel heat exchanger 120 .

[0054] In addition, in other embodiments of the present invention, those skilled in the art may also configure the body 110 to any other feasible shape, such as a spherical shape, a rectangular shape, etc., as required.

[0055] like Figure 3As shown, in some embodiments of the present invention, the middle portion of the bottom wall of the gallbladder body 110 protrudes toward the inside of the gallbladder body 110 to form an annular cavity 112 at the bottom of the gallbladder body 110, so that the microchannel heat exchanger 120 can quickly heat or cool the water in the annular cavity 112.

[0056] Those skilled in the art can understand that when there is only a small amount of water in the bile body 110, due to the presence of the annular cavity 112 at the bottom of the bile body 110, the water in the bile body 110 has a sufficient height, and thus the contact area between the water in the bile body 110 and the side wall of the bile body 110 is larger, making it easier to be heated by the bile body 110.

[0057] like Figures 1 to 3 As shown, in some embodiments of the present invention, the water bladder device 100 further includes a water inlet pipe 141 and a water outlet pipe 142 mounted on or integrally formed with the bladder body 110 , and the water inlet end of the water outlet pipe 142 is located at the bottom of the annular cavity 112 .

[0058] Furthermore, there is a certain gap between the water inlet end of the water outlet pipe 142 and the bottom wall of the annular cavity 112 to prevent the water inlet end of the water outlet pipe 142 from forming a large resistance to the water flow.

[0059] Those skilled in the art will appreciate that by locating the water inlet end of the water outlet pipe 142 at the bottom of the annular cavity 112 , the water in the bile body 110 can be discharged as much as possible through the water outlet pipe 142 .

[0060] Furthermore, in some embodiments of the present invention, the water inlet pipe 141 and / or the water outlet pipe 142 is fixedly connected to the top wall of the gallbladder body 110 or is integrally formed therewith.

[0061] In addition, in other embodiments of the present invention, those skilled in the art may also, as required, fix the water inlet pipe 141 and / or the water outlet pipe 142 to the peripheral wall or the bottom wall of the gallbladder body 110 or make them integrally.

[0062] like Figure 3 As shown, in some embodiments of the present invention, the packaging shell 130 is a foaming layer or a waterproof film formed on the outside of the body 110 and the microchannel heat exchanger 120 .

[0063] It will be understood by those skilled in the art that, by configuring the encapsulating shell 130 as a foaming layer formed on the outside of the body 110 and the microchannel heat exchanger 120, the encapsulating shell 130 can also play a role in insulating the microchannel heat exchanger 120, thereby reducing the waste of cold or heat of the microchannel heat exchanger 120 and improving the utilization rate of cold or heat of the microchannel heat exchanger 120.

[0064] In addition, in other embodiments of the present invention, those skilled in the art may also configure the packaging shell 130 to be a waterproof membrane or a waterproof plastic shell formed on the outside of the body 110 and the microchannel heat exchanger 120 as needed.

[0065] The waterproof film may be any feasible film such as a plastic film, a heat shrinkable film, etc.

[0066] from Figures 1 to 3 It can be seen that in some embodiments of the present invention, the encapsulation shell 130 completely encloses the gallbladder 110 and the microchannel heat exchanger 120 except for the water inlet pipe 141, the water outlet pipe 142, and the inlet and outlet pipes of the microchannel heat exchanger 120.

[0067] Of course, in other embodiments of the present invention, those skilled in the art will appreciate that the encapsulation shell 130 only encloses a portion of the body 110 and the microchannel heat exchanger 120. For example, the encapsulation shell 130 only encloses the body 110 and the peripheral wall of the microchannel heat exchanger 120.

[0068] Based on the above description, those skilled in the art can understand that the water bladder device 100 of the present invention has at least the following technical effects:

[0069] The service life of the microchannel heat exchanger 120 is improved: by encapsulating the body 110 and at least a portion of the microchannel heat exchanger 120 through the encapsulation shell 130, the contact between the microchannel heat exchanger 120 and the air is significantly reduced, thereby reducing condensation on the microchannel heat exchanger 120, thereby reducing corrosion caused by condensation, and significantly improving the service life of the microchannel heat exchanger 120.

[0070] Improved heat exchange efficiency: multiple fins 111 are arranged on the outside of the gallbladder body 110, and slots 121 adapted to the fins 111 are arranged on the microchannel heat exchanger 120, so that the fins 111 are embedded in the slots 121, which greatly increases the heat exchange area between the microchannel heat exchanger 120 and the gallbladder body 110 and improves the heat exchange efficiency.

[0071] Enhanced connection strength: The design of the fins 111 and the slots 121 not only improves the heat exchange efficiency, but also enables the microchannel heat exchanger 120 and the body 110 to be connected together through the fins 111 and the slots 121, thereby enhancing the connection strength between the two.

[0072] Optimize the water tank structure design: The tank body 110 is made of materials with good heat transfer performance, such as iron, stainless steel, aluminum alloy, etc., which improves the heat conduction efficiency. At the same time, the bottom of the tank body 110 is designed as an annular cavity 112, so that the water in the tank body 110 can have a large contact area with the side wall even when it is a small amount, and it is easier to be heated.

[0073] Improve the drainage efficiency of the water tank: the water inlet end of the water outlet pipe 142 is located at the bottom of the annular cavity 112, so that the water in the tank body 110 can be discharged as much as possible, thereby improving the drainage efficiency.

[0074] Diversified functions of the encapsulation shell 130: The encapsulation shell 130 can be set as a foam layer, a waterproof film or a waterproof plastic shell, which not only has the function of preventing condensation, but also has the function of heat preservation, reduces the waste of cold or heat, and improves the utilization rate.

[0075] High design flexibility: The shapes of the gallbladder body 110 and the microchannel heat exchanger 120 are flexibly designed and can be adjusted as needed. For example, the gallbladder body 110 can be set to be columnar, spherical, rectangular, etc., and the packaging shell 130 can also only wrap part of the gallbladder body 110 and the microchannel heat exchanger 120 to adapt to different application scenarios and needs.

[0076] Refer to the following Figure 4 The application of the water tank device 100 of the present invention is illustrated in combination with the water dispenser 001.

[0077] like Figure 4 As shown, in some other embodiments of the present invention, the water dispenser 001 includes a water bladder device 100 .

[0078] Furthermore, in some other embodiments of the present invention, the water dispenser 001 also includes a heat pump system 200 and a water system 300 .

[0079] The heat pump system 200 includes a compressor 210, a condenser 220, a throttling and pressure-reducing component 230, and a microchannel heat exchanger 120 of the water tank device 100, which are connected end to end in sequence to form a loop.

[0080] In other embodiments of the present invention, the throttling and pressure-reducing component 230 may be a capillary tube, an electronic expansion valve, a throttling valve with a throttling function, or any other feasible component.

[0081] The water system 300 includes a reversing valve 310, a body 110 of the water bladder device 100, and a water bladder 320. The body 110 and the water bladder 320 are fluidically connected to the reversing valve 310, respectively.

[0082] Continue reading Figure 4 In some other embodiments of the present invention, the water dispenser 001 may further include a filter 330 connected in series upstream of the reversing valve 310, so that the end of the filter 330 away from the reversing valve 310 is connected to tap water to filter the tap water.

[0083] from Figure 4 As can be seen in FIG. 1 , the water container 320 is thermally connected to the condenser 220 so that the condenser 220 heats the water in the water container 320 .

[0084] It should be noted that the water container 320 and the condenser 220 can be thermally connected together in any feasible manner.

[0085] For example, the tank body 110 and the microchannel heat exchanger 120 in the water tank device 100 can be thermally connected together in the same manner. The condenser 220 can also be configured as a metal tube wound around the water tank 320 .

[0086] Furthermore, the material of the water container 320 may refer to the above description of the container body 110 .

[0087] Continue reading Figure 4 In some other embodiments of the present invention, the water system 300 also includes an electric heater 340 connected in series downstream of the water container 320, so that when the water temperature in the water container 320 is low, the water flowing out of the water container 320 is heated by the electric heater 340, thereby meeting the user's water demand when the user is in urgent need of water.

[0088] The electric heater 340 is an electric heating wire.

[0089] Exemplarily, the electric heater 340 is an electric heating wire wound around the outside of the water pipe.

[0090] Furthermore, the water system 300 further includes a temperature sensor disposed in the water container 320, or disposed between the water container 320 and the electric heater 340, so as to detect the temperature of water flowing through the electric heater 340 through the temperature sensor. Thus, when the water temperature is low, the electric heater 340 is turned on; when the water temperature is high, the electric heater 340 is turned off.

[0091] Furthermore, although not shown in the figures, in other embodiments of the utility model, the reversing valve 310 is a four-way reversing valve, and the outlets of the reversing valve 310, the gallbladder body 110 and the electric heater 340 are respectively connected to a water outlet through a water pipe, and the water outlet can be a water nozzle.

[0092] When the reversing valve 310 is switched to a position where the filter 330 is connected to the water outlet of the reversing valve 310, the water dispenser 001 outputs water at normal temperature.

[0093] When the reversing valve 310 is switched to a position where the filter 330 is connected to the water outlet of the water container 320, the water dispenser 001 outputs hot water.

[0094] When the reversing valve 310 is switched to a position where the filter 330 is connected to the water outlet of the bile body 110, the water dispenser 001 outputs cold water.

[0095] In addition, in other embodiments of the present invention, those skilled in the art may also configure the reversing valve 310 to any other feasible reversing valve, such as a five-way reversing valve, a plurality of two-way reversing valves or three-way reversing valves in parallel, etc., as needed.

[0096] Those skilled in the art should understand that when the compressor 210 of the heat pump system 200 is working, the refrigerant circulates along the following path: compressor 210 →condenser 220 →throttling and pressure reduction component 230 →evaporator →compressor 210 .

[0097] When the refrigerant flows through the compressor 210 , it is compressed by the compressor 210 into a high-temperature and high-pressure state (liquid state or a gas-liquid mixed state).

[0098] When the refrigerant flows through the condenser 220, the refrigerant dissipates heat through the condenser 220 and is cooled to a low temperature and high pressure state (liquid state or gas-liquid mixed state).

[0099] During this process, the heat dissipated by the condenser 220 is absorbed by the water container 320 , thereby heating the water in the water container 320 .

[0100] When the refrigerant flows through the throttling and pressure reducing component 230, the refrigerant is throttled and reduced in pressure to a low temperature and low pressure state (liquid state or gas-liquid mixed state) by the throttling and pressure reducing component 230.

[0101] When the refrigerant flows through the evaporator, it absorbs heat from the external environment through the evaporator and heats up to a high-temperature and low-pressure state (gaseous state).

[0102] During this process, the evaporator absorbs heat from the vessel body 110 , thereby cooling the water in the vessel body 110 .

[0103] It should be noted that the aforementioned states of the refrigerant in the compressor 210, the condenser 220, the throttling and pressure reducing component 230, and the evaporator, i.e., the high temperature, low temperature, high pressure, and low pressure of the refrigerant, are the states of the refrigerant after it enters the corresponding components or flows out of the corresponding components compared to the states before it flows into the corresponding components.

[0104] It can be seen that the water dispenser 001 of the utility model adopts the heat pump system 200, which can make the refrigerant circulate in the compressor 210, the condenser 220, the throttling and pressure-reducing component 230 and the microchannel heat exchanger 120, thereby achieving heating and cooling of water. Not only does it improve the energy utilization efficiency, but it also significantly reduces energy consumption, making the water dispenser 001 more energy-efficient when providing hot and cold water.

[0105] So far, the technical solution of the utility model has been described in combination with the above multiple embodiments, but it is easy for those skilled in the art to understand that the protection scope of the utility model is not limited to these specific embodiments. Without departing from the technical principle of the utility model, those skilled in the art can split and combine the technical solutions in the above embodiments, and can also make equivalent changes or replacements to the relevant technical features. Any changes, equivalent replacements, improvements, etc. made within the technical concept and / or technical principle of the utility model will fall within the protection scope of the utility model.

[0106] Finally, it should be noted that in the present invention, the term "communication" means fluid communication, so as to allow fluid (such as air, liquid) to flow between two connected objects. And the "communication" can be to allow the fluid to flow between the two connected objects without leakage, or to allow the fluid to flow between the two connected objects with a little leakage.
