Description

Technical Field

[0001] This utility model relates to the field of water treatment technology, specifically to a pipeline machine. Background Technology

[0002] With the development of the times, people's requirements for drinking water are getting higher and higher, and they are usually no longer satisfied with room temperature water and hot water. Pipe-flow water dispensers can provide users with room temperature water, cold water, and hot water, and have been recognized and purchased by most people. Pipe-flow water dispensers on the market can include wall-mounted dispensers and built-in dispensers. Some dispensers integrate water purification components to purify the water source, while others connect to water purifiers and other equipment to obtain purified water.

[0003] For water dispensers that can provide chilled water, there is a cooling system inside. The cooling system needs to dissipate heat during the cooling process, so existing water dispensers are usually equipped with a high-powered fan to provide sufficient air for heat dissipation.

[0004] Not only do fan-equipped water dispensers generate significant noise during operation, but for those used in relatively enclosed spaces, such as embedded water dispensers, poor air circulation causes heat generated by the cooling components to accumulate inside the device, affecting not only the performance of the water dispenser but also its lifespan. Utility Model Content

[0005] To at least partially address the problems existing in the prior art, some embodiments of this utility model provide a pipeline machine with a main water inlet and a main water outlet, including a water storage tank, the inlet of which is connected to the main water inlet via a water supply pipe, and the outlet of which is connected to the main water outlet via a normal temperature water pipe; a cooling water tank, the inlet of which is connected to the outlet of which is connected via a water storage pipe, so that the water storage tank stores water into the cooling water tank; and a cold tank, which includes a cold water chamber, a refrigeration component, and a water-cooling component. The inlet of the water chamber is connected to the outlet of the water storage tank via an inlet pipe, and the outlet of the cold water chamber is connected to the main outlet via a cold water pipe. The cold end of the refrigeration component can exchange heat with the cold water chamber, and the hot end of the refrigeration component can also exchange heat with the water-cooling component. The water-cooling component includes a water-cooling inlet and a water-cooling outlet. The water-cooling inlet is connected to the outlet of the cooling water tank via a first water-cooling pipe, and the water-cooling outlet is connected to the inlet of the cooling water tank via a second water-cooling pipe. A circulation pump is installed on either the first or second water-cooling pipe. In this technical solution, the refrigeration component can be cooled by water cooling, eliminating the need for a fan with high airflow velocity and significantly reducing the noise of the water dispenser during operation. Using the cooling water tank as the cooling water source simplifies the structure of the water dispenser and has almost no impact on the user's access to room temperature water from the water storage tank. For water dispensers using semiconductor cooling, noise levels during operation can be further reduced. Furthermore, for dispensers installed in relatively enclosed spaces, such as embedded models, cooling efficiency is not reduced as much as existing water dispensers or water purifiers due to obstructed air inlets and outlets, and heat accumulation is generally avoided. Water cooling via a cooling tank also has virtually no impact on the user's ability to access room-temperature water from the storage tank.

[0006] For example, the water storage tank has a first water storage outlet as its outlet, and the cooling water tank has a first cooling water inlet as its inlet. A water storage pipeline connects the first water storage outlet and the first cooling water inlet. The bottom wall of the cooling water tank is lower than the lower of the first water storage outlet and the first cooling water inlet. Through proper design, water replenishment to the cooling water tank can be achieved even with relatively simple structures for both the water storage tank and the cooling water tank, and the water in the cooling water tank will not flow back into the water storage tank after replenishment.

[0007] For example, the cooling water tank inlet also includes a second cooling water inlet, and a second water-cooling pipeline is connected between the water-cooling outlet and the second cooling water inlet. The second cooling water inlet is lower than the first cooling water inlet. During operation, cooling water will not flow into the cooling water tank from above the water surface, thus avoiding the sound of running water from the water dispenser affecting the user experience. There is also no risk of cooling water flowing back into the first cooling water inlet and back into the storage water tank.

[0008] For example, the water storage tank has a second water outlet located at its bottom, and the cold water chamber is located below the water storage tank. Water in the water storage tank can be replenished into the cold water chamber under gravity, eliminating the need for a water pump.

[0009] For example, a one-way valve is installed on the water storage pipeline. This prevents the water temperature in the storage tank from rising and making it impossible for users to access room temperature water.

[0010] For example, the water dispenser also includes a first water level detector for detecting the water level in the storage tank; a second water level detector for detecting the water level in the cooling tank; an inlet control valve connected in series on the water supply pipeline; and a controller electrically connected to the first water level detector, the second water level detector, and the inlet control valve. The controller is used to control the inlet control valve to open when the water level in the storage tank is lower than the first lower limit or the water level in the cooling tank is lower than the second lower limit. In summary, by setting the first water level detector, the second water level detector, the inlet control valve, and the controller, the water dispenser can automatically replenish water when the water level in the storage tank or the cooling tank is insufficient.

[0011] For example, the water dispenser also includes a hot water pipe connected between the outlet of the cooling tank and the main outlet; and a heating element connected in series on the hot water pipe. This not only provides users with a larger flow rate of hot water at a higher temperature, but also saves energy.

[0012] For example, the water dispenser also includes a chilled water pump, which is connected in series on the chilled water pipeline. The chilled water pump can pump chilled water to a height above the chilled water chamber or above the liquid level in the water storage tank, which can effectively increase the water flow rate and improve the user experience.

[0013] For example, the pipeline machine also includes a room temperature water pump, which is connected in series on the room temperature water pipeline. The room temperature water pump also allows for an unrestricted height of the main outlet and provides a larger flow rate of room temperature water.

[0014] For example, a chilled water pump is connected in series with the water inlet pipe, and the chilled tank is only connected to the outside world through the chilled water pipe. Therefore, the chilled tank does not have a vent for balancing air pressure, resulting in a simpler structure. By not connecting to the atmosphere through a vent, foreign objects, dust, and bacteria can be prevented from entering the chilled tank, making it less prone to bacterial growth and allowing for simple maintenance such as evacuation.

[0015] For example, the cooling component includes a thermoelectric cooler. The thermoelectric cooler does not require a refrigerant, making it safer and more environmentally friendly. It has no moving parts, making it more shock-resistant and longer-lasting. During operation, the thermoelectric cooler produces almost no noise.

[0016] For example, the water-cooling component includes a water block. Water blocks have mature manufacturing processes, low production costs, and are easy to procure in bulk. Optionally, the water block has meandering water-cooling channels throughout its interior, providing excellent heat exchange capabilities.

[0017] For example, the height of the water cooling inlet is lower than that of the water cooling outlet. This allows the cooling water to completely fill the water cooling channels, and almost no air bubbles are generated that would affect the water cooling effect.

[0018] This utility model description introduces a series of simplified concepts, which will be further explained in detail in the detailed description section. This utility model description is not intended to limit the key features and essential technical features of the claimed technical solution, nor is it intended to determine the scope of protection of the claimed technical solution.

[0026] In the following description, numerous details are provided to enable a thorough understanding of the present invention. However, those skilled in the art will appreciate that the following description merely illustrates preferred embodiments of the present invention, which may be practiced without one or more of these details. Furthermore, to avoid confusion with the present invention, some technical features well-known in the art have not been described in detail.

[0027] To fully understand the embodiments of this utility model, a detailed structure will be presented in the following description. Obviously, the implementation of the embodiments of this utility model is not limited to the specific details familiar to those skilled in the art. Preferred embodiments of this utility model are described in detail below; however, in addition to these detailed descriptions, this utility model may have other embodiments.

[0028] This utility model provides a pipeline machine according to an embodiment. The pipeline machine according to an embodiment of this utility model will be described in detail below with reference to the accompanying drawings. Figure 1 As shown, the water dispenser has a main inlet 10 and a main outlet 20. The main inlet 10 can be used to obtain a water source, for example, it can be connected to the outlet of a water purifier. The main outlet 20 can provide users with water that has been stored and / or processed by the water dispenser. Specifically, the water dispenser can store purified water from the main inlet 10 and provide room temperature water to users through the main outlet 20. In this case, the water dispenser may include a water storage tank 100. Alternatively, the water dispenser can heat or cool the water from the water purifier before providing it to users. Optionally, the main outlet 20 can be connected to a faucet or spout. Optionally, the main outlet 20 can have multiple separate openings, so that water that has undergone different treatments, such as cooled or heated water, can be provided to users through different openings without interference. The inlet of the water storage tank 100 can be connected to the main water inlet 10 via a water supply pipe 400, and the outlet of the water storage tank 100 can be connected to the main water outlet 20 via a room temperature water pipe 500. In the embodiment where the main water inlet 10 is connected to the water purifier, the water storage tank 100 can store a large amount of purified water extracted by the water purifier, and provide the product to the user through the water storage tank 100 when the user draws water. This can reduce the number of times the water purifier is started and stopped, and extend the service life of the water purifier.

[0029] The water dispenser may also include a cold tank 300. The cold tank 300 may include a chilled water chamber (not shown) disposed therein. Optionally, the chilled water chamber may have a shape substantially the same as the main body of the cold tank 300, being cubic in shape. Optionally, the cold tank 300 may have tortuous pipes formed inside, with the chilled water chamber having an inner cavity formed by the pipes, thereby increasing the inner surface area of ​​the chilled water chamber. The cold tank 300 may also include a refrigeration assembly, which may include a compressor-type refrigeration assembly, a semiconductor refrigeration assembly, or other existing or future refrigeration assemblies. Regardless of the type of refrigeration assembly, heat is generated during the refrigeration process, causing one part of the refrigeration assembly to form a hot end and the other part to form a cold end. The cold end of the refrigeration assembly can exchange heat with the chilled water chamber, thereby cooling the water in the chilled water chamber. The inlet of the chilled water chamber is connected to the outlet of the water storage tank 100 via an inlet pipe, and the outlet of the chilled water chamber is connected to the main outlet 20 via a chilled water pipe 600. Thus, the water dispenser can provide users with chilled water below room temperature.

[0030] For any existing type of refrigeration component, the cooling efficiency decreases when the temperature difference between its hot and cold ends is too large. Taking semiconductor refrigeration as an example, when the temperature difference between its hot and cold ends exceeds 50 degrees Celsius, its cooling effect becomes almost negligible, causing the water temperature in the cooling tank 300 to stop decreasing, making it difficult for the water dispenser to provide the required temperature of chilled water. Therefore, the hot end of the refrigeration component needs to be cooled. The hot end of the refrigeration component can exchange heat with the water-cooling component 710, which can transfer the heat from the hot end to the cooling water. Since water has a much higher specific heat capacity than air, the temperature rise of the same volume of water is much less than that of the same volume of air during the process of water passing through the water cooling head. Thus, only a very small flow rate of cooling water is needed to achieve the same cooling effect as a larger flow rate of air. Experiments show that with a cooling power of 60W and a temperature difference of 10 degrees Celsius between the chilled water and the air, an air flow rate of 279 L / min is required. However, with the same cooling power of 60W and a temperature difference of 5 degrees Celsius between the chilled water and the cooling water, a water flow rate of only 170 mL / min is required.

[0031] The water dispenser may also include a cooling water tank 200, and a water-cooling assembly 710 including a water-cooling inlet and a water-cooling outlet. The water-cooling inlet is connected to the outlet of the cooling water tank 200 via a first water-cooling pipe 701, and the water-cooling outlet is connected to the inlet of the cooling water tank 200 via a second water-cooling pipe 702. A circulation pump 720 is installed on either the first water-cooling pipe 701 or the second water-cooling pipe 702. The circulation pump 720 may include various suitable water pumps such as peristaltic pumps, diaphragm pumps, and centrifugal pumps. Thus, the cooling water tank 200 can supply cooling water to the water-cooling assembly 710. The larger the volume of the cooling water tank 200, the more heat it can store when full, ensuring that the cooling water passing through the water-cooling assembly 710 remains at a low temperature. Conversely, the smaller the volume of the cooling water tank 200, the less heat it can store when full.

[0032] In some embodiments, the cooling assembly includes a compressor and refrigerant circulation piping. In this case, the water-cooling assembly 710 may be configured as nested piping, with one of the refrigerant and cooling water flowing in the inner pipe of the water-cooling assembly 710, and the other flowing between the outer wall of the inner pipe and the outer pipe. Optionally, the water-cooling assembly 710 may include heat sinks and water pipes made of thermally conductive material embedded in the heat sinks. Optionally, the water-cooling assembly 710 may include a water cooling head. For semiconductor coolers, since they do not have piping structures, the water-cooling assembly 710 may employ a planar component such as the water cooling head described above.

[0033] The inlet of the cooling water tank 200 is connected to the outlet of the storage tank 100 via a water storage pipe 900, allowing the storage tank 100 to store water into the cooling water tank 200. Optionally, a water pump can be installed on the water storage pipe 900 to draw water from the storage tank 100 into the cooling water tank 200. Optionally, a one-way valve 910 can be installed on the water storage pipe 900 to ensure that water in the storage tank 100 flows only unidirectionally into the cooling water tank 200 (see reference). Figure 3C Optionally, the water storage tank 100 and the cooling water tank 200 form a communicating vessel, such that the water level in the water storage tank 100 and the water level in the cooling water tank 200 are at the same height. Preferably, the water in the cooling water tank 200 can only flow back to the water storage tank 100 in a small amount or cannot flow back to the water storage tank 100, thereby avoiding the water temperature in the water storage tank 100 from rising and making it impossible for the user to access room temperature water.

[0034] In the above technical solution, water cooling can be used to dissipate heat from the cooling components, eliminating the need for a fan with high airflow velocity and significantly reducing the noise level of the water dispenser during operation. Using a cooling water tank 200 as the source of cooling water simplifies the structure of the water dispenser and has virtually no impact on the user's access to room-temperature water in the storage tank 100. For water dispensers using semiconductor cooling, the noise level can be further reduced. Furthermore, for water dispensers installed in relatively enclosed spaces, such as embedded water dispensers, the cooling efficiency is not reduced as much as in existing water dispensers or water purifiers due to obstructed air inlets and outlets, and heat accumulation is generally avoided. Water cooling via the cooling water tank 200 also has virtually no impact on the user's access to room-temperature water in the storage tank 100.

[0035] As described above, preferably, the cooling component may include a semiconductor cooler. Semiconductor coolers do not require refrigerants, making them safer and more environmentally friendly. They have no moving parts, making them more shock-resistant and longer-lasting. During operation, semiconductor coolers produce almost no noise. Preferably, the water-cooling component 710 may include a water block. Water block technology is mature, production costs are low, and bulk purchasing is convenient. Optionally, the water block has a meandering water-cooling channel that extends throughout its interior, providing excellent heat exchange capabilities. Preferably, the height of the water inlet can be lower than the water outlet. This ensures that the cooling water completely fills the water-cooling channel, minimizing the formation of air bubbles that could affect the cooling effect.

[0036] For example, the outlet of the water storage tank 100 may include a first water storage outlet 110, and the inlet of the cooling water tank 200 may include a first cooling inlet 210. A water storage pipe 900 connects the first water storage outlet 110 and the first cooling inlet 210. The bottom wall of the cooling water tank 200 is lower than the lower of the first water storage outlet 110 and the first cooling inlet 210. The water level in the water storage tank 100 may be higher than either the first water storage outlet 110 or the first cooling inlet 210. Thus, the bottom wall of the cooling water tank 200 is also lower than the water level in the water storage tank 100, and water in the water storage tank 100 can be replenished to the cooling water tank 200 through the water storage pipe 900. When the water storage tank 100 is full, the water overflows into the cooling water tank 200 until the water level in the water storage tank 100 drops to the higher of the first water outlet 110 and the first cooling inlet 210 (ignoring the siphon effect), or to the same level as the cooling water tank 200. This eliminates the need for a water pump, allowing the cooling water tank 200 to be filled simultaneously with the water storage tank 100. Specifically, as... Figure 3AAs shown, optionally, the first water outlet 110 is higher than the first cooling inlet 210. After replenishing the water tank 100 with water to a level higher than the first water outlet 110, water is continued to be added for a period of time. When the water levels in the water tank 100 and the cooling tank 200 are balanced after water replenishment stops, the water level in the water tank 100 is level with the first water outlet 110, and the water level in the cooling tank can be lower than or equal to the height of the first water outlet 110. Figure 3B As shown, optionally, the first water outlet 110 is lower than the height of the first cooling inlet 210. After replenishing the water tank 100 with water to a level higher than the first cooling inlet 210, water is continued to be added for a period of time. When the water levels in the water tank 100 and the cooling tank 200 are balanced after water replenishment stops, the water level in the water tank 100 is level with the first cooling inlet 210, and the water level in the cooling tank can be lower than or equal to the height of the first cooling inlet 210. Of course, the figure only shows an embodiment in which the bottom wall heights of the water tank 100 and the cooling tank 200 are the same, and this application does not exclude embodiments in which the bottom wall heights of the water tank 100 and the cooling tank 200 are different. It should be noted that the same structures in the above figures use the same reference numerals.

[0037] like Figure 1 and Figure 2 In the illustrated embodiment, the water storage pipe 900 can be horizontal. When the highest water level in the water storage tank 100 is slightly higher than that in the water storage pipe 900, the water in the water storage tank 100 overflows into the cooling water tank 200. Optionally, when the water level in the cooling water tank 200 reaches a certain height, water replenishment to the water storage tank 100 is stopped, allowing all the water in the water storage tank 100 above the water storage pipe 900 to enter the cooling water tank 200. Thus, the water levels in both the water storage tank 100 and the cooling water tank 200 are not higher than those in the water storage pipe 900. Therefore, almost no heat exchange occurs between the water storage tank 100 and the cooling water tank 200, and the water temperature in the water storage tank 100 does not rise due to the circulation of cooling water. This structure is relatively simple and easy to manufacture. Optionally, the water storage tank 100 and the cooling water tank 200 can be constructed as a single unit, separated by a partition. The water storage pipe 900 can be an opening on the partition, or formed by the upper edge of the partition and the inner wall of the tank. In short, through reasonable design, water replenishment to the cooling water tank 200 can be achieved even with a relatively simple structure for the water storage tank 100 and the cooling water tank 200, and the water in the cooling water tank 200 will not flow back into the water storage tank 100 after replenishment.

[0038] For example, the cooling water tank 200 further includes a second cooling water inlet 220, and a second water-cooling pipe 702 is connected between the water-cooling outlet and the second cooling water inlet 220. The second cooling water inlet 220 is lower than the first cooling water inlet 210. As described above, the cooling water tank 200 is replenished with water below the cooling water inlet. In some embodiments, the liquid level in the cooling water tank 200 will not be higher than the first cooling water inlet 210. In this case, since the second cooling water inlet 220 is lower than the first cooling water inlet 210, cooling water will not flow into the cooling water tank 200 from above the water surface during operation, thereby avoiding the sound of running water from the water dispenser affecting the user experience. There is also no risk of cooling water flowing back into the first cooling water inlet 210 and back into the water storage tank 100.

[0039] For example, the outlet of the water storage tank 100 may include a second water outlet 120 located at its bottom, and the cold water chamber is located below the water storage tank 100. Water in the water storage tank 100 can be replenished into the cold water chamber under gravity, eliminating the need for a water pump. In these embodiments, optionally, the main outlet 20 may be no higher than the cold water chamber and may be equipped with a faucet with a shut-off function. When a user needs cold water, the faucet can be turned on, and water can be supplied to the user under gravity. Optionally, the cold water chamber may be located entirely or partially below the water storage tank 100. Optionally, the cold water chamber may not have a vent communicating with the atmosphere, thus allowing water to fill the entire cold water chamber. Optionally, the cold water chamber may have a vent that is higher than the liquid level in the water storage tank 100, thereby preventing water from overflowing from the vent.

[0040] For example, the water dispenser may also include a hot water pipe 800 and a heating element 810 connected in series on the hot water pipe 800. The heating element 810 may include, but is not limited to, existing or future heating elements such as thick-film heaters, hot water tanks, and electromagnetic heaters. The hot water pipe 800 is connected between the outlet of the cooling water tank 200 and the main outlet 20. Thus, water in the cooling water tank 200 at a temperature higher than room temperature can be reheated by the heating element 810 and supplied to the user. This not only provides users with a larger flow rate of higher-temperature hot water but also saves energy. Figure 2 In the embodiment shown, a hot water pump 820 for pumping water to be reheated can also be installed on the hot water pipe 800. Optionally, the hot water pump 820 can control the flow rate, so that the water dispenser can provide users with hot water at a more accurate temperature.

[0041] For example, the water dispenser also includes a first water level detector and a second water level detector. The first water level detector is used to detect the water level in the water storage tank 100, and the second water level detector is used to detect the water level in the cooling water tank 200. The first and second water level detectors include, but are not limited to, existing or future water level detection elements, such as ultrasonic water level sensors, float sensors, infrared liquid level sensors, and laser liquid level sensors. The water dispenser also includes an inlet control valve 410, which is connected in series on the water supply pipeline 400 to control the opening and closing of the water supply pipeline 400. As described above, the main water inlet 10 can be connected to a water purifier. When the inlet control valve 410 is open, water can be supplied to the water storage tank 100 and the cooling water tank 200; when the inlet control valve 410 is closed, water supply can be stopped. The pipeline machine may include a controller, which is electrically connected to a first water level detector, a second water level detector and an inlet control valve 410. The controller is used to control the inlet control valve 410 to open when the water level in the water storage tank 100 is lower than the first water level lower limit or the water level in the cooling water tank 200 is lower than the second water level lower limit.

[0042] Specifically, the controller can be built using electronic components such as timers, comparators, registers, and digital logic circuits, or implemented using processor chips such as microcontrollers, microprocessors, programmable logic controllers (PLCs), digital signal processors (DSPs), field-programmable gate arrays (FPGAs), programmable logic arrays (PLAs), and application-specific integrated circuits (ASICs) and their peripheral circuits.

[0043] As described above, the cooling water tank 200 can provide users with reheated water, causing the water level in the cooling water tank 200 to drop. Optionally, the second lower limit of the water level in the cooling water tank 200 can be higher than the first lower limit of the water level in the storage tank 100, thereby avoiding the water level in the cooling water tank 200 being too low, resulting in insufficient cooling water required for water cooling. In a specific embodiment, at the first lower limit of the water level, the storage tank 100 may be almost empty, while at the second lower limit of the water level, the cooling water tank 200 can still retain the amount of water required for the operation of the water cooling component 710. In summary, by setting a first water level detector, a second water level detector, an inlet control valve 410, and a controller, the water dispenser can automatically replenish water when the water level in the storage tank 100 or the cooling water tank 200 is insufficient.

[0044] For example, the water dispenser may also include a cold water pump 610, which is connected in series on the cold water pipeline 600. The cold water pump 610 can pump cold water to a height above the cold water chamber or above the water level in the storage tank by 100, which can effectively increase the water flow rate and improve the user experience. For example, the water dispenser may also include a room temperature water pump 510, which is connected in series on the room temperature water pipeline 500. Similar to the cold water pump 610, the room temperature water pump 510 can also make the height of the total outlet 20 unrestricted and provide a larger flow rate of room temperature water.

[0045] For example, a cold water pump 610 can be connected in series in the water inlet pipe, and the cold tank 300 is only connected to the outside world through the cold water pipe 600. When the user needs cold water, the cold water pump 610 can draw room temperature water from the water storage tank 100 to replenish the cold tank 300, and squeeze the cold water in the cold tank 300 into the cold water pipe 600. Therefore, the cold tank 300 does not have a vent for balancing air pressure, and its structure is relatively simple. By not connecting to the atmosphere through a vent, foreign objects, dust, and bacteria can be prevented from entering the cold tank 300, making it less prone to bacterial growth inside, and allowing for simple maintenance such as evacuation.

[0046] In the description of this utility model, it should be understood that the directional terms such as "front", "rear", "up", "down", "left", "right", "horizontal", "vertical", "horizontal", "top", and "bottom" indicate the orientation or positional relationship, which are usually based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this utility model. The directional terms "inner" and "outer" refer to the inner and outer contours of each component itself.
