Description

TECHNICAL FIELD

[0001] The utility model relates to water treatment technical field, specifically, relate to a kind of embedded pipeline machine. BACKGROUND

[0002] With the development of the times, people's requirements for drinking water are getting higher and higher, and it is usually not satisfied with normal temperature water and hot water. Pipeline machine can provide normal temperature water, cold water and hot water and other products for users, and has been recognized and purchased by most people. The pipeline machine on the market can include wall-mounted pipeline machine, embedded pipeline machine and the like. Some pipeline machines integrate water purification components, which can purify water sources, and other pipeline machines are connected to water purification machines and other equipment to obtain purified water.

[0003] For the pipeline machine that can provide cold water, a refrigeration component is provided inside. The refrigeration component needs to be cooled during refrigeration, so the existing pipeline machine usually has a fan with large power to provide sufficient air for cooling.

[0004] For example, for embedded pipeline machines, due to poor air circulation, heat generated by the refrigeration component accumulates inside the device, which not only affects the performance of the pipeline machine, but also may affect its service life. At the same time, due to the power limitation, the high-temperature hot water it can provide has a flow limitation, and the user experience is not good. SUMMARY

[0005] In order to at least partially solve the problems existing in the prior art, some embodiments of the utility model provide an embedded pipeline machine having a total water inlet and a total water outlet, comprising: a cold tank, the cold tank comprising a cold water cavity, a refrigeration component and a heat dissipation component, the refrigeration component comprising a cold end and a hot end, the cold end being used for heat exchange with the cold water cavity, the heat dissipation component being used for heat dissipation of the hot end, a water inlet of the cold water cavity being connected to the total water inlet through a cold tank water supplement pipeline, a water outlet of the cold water cavity being connected to the total water outlet; and a hot water tank, a water inlet of the hot water tank being connected to the total water inlet through a hot water supplement pipeline, wherein: a water outlet of the hot water tank is connected to the total water outlet through a hot water pipeline, a flow-type heating body is arranged on the hot water pipeline, the water outlet of the hot water tank is connected to the water inlet of the hot water tank through a circulation pipeline, a circulating water pump is arranged on the circulation pipeline, the circulating water pump is used to form a water flow from the water outlet to the water inlet of the hot water tank in the circulation pipeline, and the circulation pipeline is used for heat exchange with the heat dissipation component. In the above technical solution, most of the heat generated by the refrigeration component is transferred to the hot water tank through the cooling water in the circulation pipeline, thereby playing a function of preheating the normal temperature water in the hot water tank and reducing energy waste. When the user takes high-temperature hot water, the preheated water is heated again to provide the user, and the water outlet flow is large, which can meet the user's demand. Only a small amount of heat from the heat dissipation component is diffused into the air, so there is no need to set a fan for active heat dissipation, and the normal operation of the refrigeration component can also be ensured.

[0006] Exemplarily, the heat dissipation assembly comprises a substrate and a plurality of heat dissipation fins arranged on a first surface of the substrate, a second surface of the substrate opposite to the first surface being attached to the hot end; at least a portion of the circulation pipeline is embedded into the gaps between the plurality of heat dissipation fins, and the surface of the circulation pipeline is attached to the plurality of heat dissipation fins and / or the substrate. In summary, the heat dissipation assembly thus arranged is not only more suitable for the semiconductor refrigerator, but also can more efficiently transfer most of the heat to the cooling water of the circulation pipeline, and a small part of the heat is dissipated to the air.

[0007] Exemplarily, at least a portion of the circulation pipeline comprises a plurality of straight pipe sections and a plurality of elbow pipe sections arranged alternately and connected to each other, and the plurality of straight pipe sections are respectively embedded into the plurality of gaps between the plurality of heat dissipation fins. In this way, the cooling water circulating through the heat dissipation assembly can carry away enough heat, so that the circulation pump pumping the same volume of cooling water can have a better cooling effect, thereby improving the efficiency of the circulation pump.

[0008] Exemplarily, along the direction away from the first surface of the substrate, the plurality of heat dissipation fins protrude from at least a portion of the circulation pipeline. In this way, a large enough contact area with the air can be achieved, thereby also making the passive air cooling effect of the heat dissipation assembly better. After long-term use, even if the circulation pipeline moves in the direction protruding towards the heat dissipation fins due to vibration or the like, it will not fall off from the heat dissipation assembly.

[0009] Exemplarily, the embedded pipeline machine further comprises a cold water tank connected in series to the cold tank water supplement pipeline, and a cold water pump connected in series to the cold tank water supplement pipeline between the cold water tank and the cold tank. In this way, when the user takes cold water, the water to be refrigerated can be obtained from the cold water tank first, and the water source is obtained from the water purifier only when the water level in the cold water tank is low, thereby prolonging the service life of the water purifier. The cold water pump can pump cold water to a height higher than the cold water chamber or above the liquid level of the cold water tank, which can effectively increase the water flow and improve the user experience.

[0010] Exemplarily, the pipeline machine further comprises a water inlet control valve, the cold tank water supplement pipeline and the hot water supplement pipeline are connected to the total water inlet through the water inlet control valve, and the hot water tank comprises a first water level lower limit detection assembly for detecting whether the water level in the hot water tank is lower than the hot water lower limit. The opening condition of the water inlet control valve comprises that the water level of the hot water tank is lower than the hot water lower limit. In this way, the hot water tank can be supplemented in time when the water level is too low.

[0011] Exemplarily, the water inlet of the hot water tank is connected with a first float switch, which closes the water inlet of the hot water tank when the water level in the hot water tank reaches a first upper limit of the hot water level. In the embodiment provided with the first float switch, the water inlet control valve can still be open when the water level in the hot water tank reaches the first upper limit of the hot water level, and the water path is only cut off by the float switch to prevent water overflow.

[0012] Exemplarily, the inline water line machine further comprises a cold water tank, which is arranged in series on the cold tank water replenishing pipeline; and a second lower limit of water level detection assembly, which is used to detect whether the water level in the cold water tank is lower than a lower limit of the cold water level. The opening condition of the water inlet control valve further comprises that the water level in the cold water tank is lower than the lower limit of the cold water level. In this way, the situation that one of the hot water tank and the cold water tank is already empty but the replenishment is still not performed can be avoided.

[0013] Exemplarily, the water inlet of the cold water tank is connected with a second float switch, which closes the water inlet of the cold water tank when the water level in the cold water tank reaches a first upper limit of the cold water level. In the situation that the cold water tank is replenished while the hot water tank is still replenished, the second float switch can prevent water overflow in the cold water tank.

[0014] Exemplarily, the hot water tank further comprises a first upper limit of water level detection assembly, which is used to detect whether the water level in the hot water tank is higher than a second upper limit of the hot water level, and the cold water tank further comprises a second upper limit of water level detection assembly, which is used to detect whether the water level in the cold water tank is higher than a second upper limit of the cold water level. The closing condition of the water inlet control valve comprises that the water level in the hot water tank is higher than the second upper limit of the hot water level and the water level in the cold water tank is higher than the second upper limit of the cold water level. When the hot water tank and the cold water tank are both replenished, the water level information sent by the first upper limit of water level detection assembly and the second upper limit of water level detection assembly can be used to determine that the replenishment is not needed and the water inlet control valve is closed. In this way, the situation that the water replenishment is performed from the water purifier as soon as the water level decreases to the opening position of the float switch does not exist. Therefore, the start-stop frequency of the water purifier can be reduced and the service life of the water purifier can be prolonged.

[0015] Exemplarily, the water inlet of the hot water tank is connected with a first float switch, which closes the water inlet of the hot water tank when the water level in the hot water tank reaches a first upper limit of the hot water level, and the first upper limit of the hot water level is not lower than a second upper limit of the hot water level. In this way, it can be ensured that the water level in the hot water tank can be replenished to the second upper limit of the hot water level and cannot be prevented from reaching the second upper limit of the hot water level due to the closing of the first float switch before reaching the second upper limit of the hot water level.

[0016] Exemplarily, the water inlet of the cold water tank is connected with a second float switch, and the second float switch is configured to close the water inlet of the cold water tank when the water level of the cold water tank reaches a first upper limit of the cold water level, wherein the first upper limit of the cold water level is not lower than the second upper limit of the cold water level. In summary, the water inlet control valve can be closed when the hot water tank and the cold water tank are being filled, so as to prevent the water replenishment from the water purifier once the water level drops to the opening position of the float switch. In this way, the start-stop frequency of the water purifier is reduced, and the service life of the water purifier is prolonged.

[0017] Exemplarily, the pipeline machine further comprises a water inlet control valve, the hot water replenishment pipeline is connected to the total water inlet via the water inlet control valve, the cold tank replenishment pipeline is connected to a first predetermined position of the hot water replenishment pipeline, the cold tank replenishment pipeline is connected to the total water inlet through the hot water replenishment pipeline upstream of the first predetermined position, the first predetermined position is located downstream of the water inlet control valve, the water outlet of the circulation pipeline is connected to a second predetermined position of the hot water replenishment pipeline, the water inlet of the circulation pipeline is connected to the water outlet of the hot water tank, the second predetermined position is located downstream of the first predetermined position, a first one-way valve is connected in series to the hot water replenishment pipeline, the first one-way valve is located between the first predetermined position and the second predetermined position, a second one-way valve is connected in series to the circulation pipeline, and the water inlet control valve is closed when the circulation water pump is started. In this way, the first one-way valve is arranged to prevent the circulation pipeline from being under pressure, so as to avoid water leakage when a hose is present. The first one-way valve can also prevent the water under pressure from flowing back to the total water outlet or flowing back into the hot water tank, so as to prevent the hot water tank from overflowing. The second one-way valve can prevent the circulating cooling water from entering the cold water tank, so as to affect the temperature of the cold water. The water inlet control valve is closed when the circulation pump is started, so as to prevent the hot water tank from being excessively replenished, which causes the first float switch to be closed and the circulating water to be unable to return to the hot water tank.

DETAILED DESCRIPTION

[0026] In the following description, a large number of details are provided in order to allow a thorough understanding of the present utility model. However, it can be appreciated by those skilled in the art that the following description only exemplarily shows the preferred embodiments of the present utility model, and the present utility model can be implemented without one or more such details. In addition, in order to avoid confusion with the present utility model, some technical features known in the art are not described in detail.

[0027] In order to thoroughly understand the embodiments of the present utility model, detailed structures will be proposed in the following description. Obviously, the implementation of the embodiments of the present utility model is not limited to the special details familiar to those skilled in the art. The preferred embodiments of the present utility model are described in detail as follows, however, in addition to these detailed descriptions, the present utility model can also have other embodiments.

[0028] The embodiments of the present utility model provide an embedded pipeline machine. The embedded pipeline machine according to the embodiments of the present utility model will be introduced in detail below in combination with the drawings. As shown in the drawings, Figure 1As shown, the embedded water dispenser has a main inlet 10 and a main outlet 20. The main inlet 10 can be used to obtain a water source, such as connecting to the outlet of a water purifier. The main outlet 20 can provide the user with water that has been stored and / or processed by the embedded water dispenser. Specifically, the embedded water dispenser can store purified water from the main inlet 10 and provide room temperature water to the user through the main outlet 20. In this case, the embedded water dispenser may include a water tank (e.g., a hot water tank 200 and a cold water tank 600 mentioned below). Alternatively, the embedded water dispenser can heat or cool the water from the water purifier before providing it to the user. 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 the user through different openings without interference.

[0029] The embedded pipeline machine may also include a cold tank 100, which may include a cold water chamber (not shown) disposed therein. Figure 3 As shown, optionally, the cold water chamber can have a shape substantially the same as the main body of the cold tank 100, being cubic. Optionally, the cold tank 100 can have tortuous pipes formed inside, with the cold water chamber having an inner cavity formed by the pipes, thereby increasing the inner surface area of ​​the cold water chamber. The cold tank 100 may also include a refrigeration component, which may include a compressor-type refrigeration component, a semiconductor refrigeration component, or other existing or future refrigeration components. Regardless of the type of refrigeration component, heat is generated during the refrigeration process, causing one part of the refrigeration component to form a hot end and the other part to form a cold end. The cold end of the refrigeration component is used for heat exchange with the cold water chamber, thereby cooling the water in the cold water chamber. The inlet of the cold water chamber is connected to the main inlet 10 via the cold tank water supply pipe 410, and the outlet of the cold water chamber is connected to the main outlet 20. Thus, the embedded water dispenser can provide users with cold water at 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 reaches more than 50 degrees Celsius, its cooling effect is almost negligible, causing the water temperature in the cold tank 100 to stop decreasing, making it difficult for the embedded pipeline machine to provide the required temperature of cold water. Therefore, the hot end of the refrigeration component needs to be cooled. The heat dissipation component 300 is used to dissipate heat from the hot end. Specifically, the heat dissipation component 300 may include heat sinks that can contact the air and exchange heat with the surrounding air. The refrigeration component in the figure is not shown; it is positioned between the ice tank and the heat dissipation component 300.

[0031] The embedded pipeline machine can include a hot water tank 200, and a water inlet of the hot water tank 200 can be connected to the total water inlet 10 through a hot water supplement pipeline 420. A water outlet of the hot water tank 200 is connected to the total water outlet 20 through a hot water pipeline 430, and a flow-through heating body 500 can be arranged on the hot water pipeline 430. The flow-through heating body 500 can include, but is not limited to, a thick-film heating body, an electromagnetic heater, and other existing or future heating elements. The flow-through heating body 500 hardly stores hot water, and only heats when water passes through, so the temperature of the output hot water can be adjusted in real time by adjusting the heating power, and the lagging condition is better than that of the hot tank outlet. The water outlet of the hot water tank 200 can be connected to the water inlet of the hot water tank 200 through a circulation pipeline 440, and a circulating water pump can be arranged on the circulation pipeline 440. The circulating water pump is used to form a water flow from the water outlet to the water inlet of the hot water tank 200 in the circulation pipeline 440, and the circulation pipeline 440 is used for heat exchange with the heat dissipation assembly 300. The circulating water pump can include a peristaltic pump, a diaphragm pump, a centrifugal pump, and other suitable water pumps. The circulation pipeline 440 can be made of a heat-conducting material. Alternatively, at least a portion of the circulation pipeline 440 is made of metal, such as stainless steel. Alternatively, the circulation pipeline 440 can also be made of materials such as heat-conducting rubber, heat-conducting ceramic, and the like.

[0032] In addition to transferring heat to the air, the heat dissipation assembly 300 can also transfer most of the heat of the hot end to the cooling water in the circulation pipeline 440. Since water has a specific heat capacity much larger than air, the temperature rise of the same volume of water during its passage through the heat dissipation assembly 300 is much smaller than that of the same volume of air. Therefore, only a small flow rate of cooling water is needed to achieve the same cooling effect as a larger flow rate of air. The water to be heated in the hot water tank 200 can be driven to circulate by the circulating water pump in the circulation pipeline 440, and absorb part of the heat when passing through the heat dissipation assembly 300. Therefore, the water temperature in the hot water tank 200 can be higher than room temperature, and after being heated twice by the flow-through heating body 500, a larger flow rate of higher temperature hot water can be provided to the user. The embedded pipeline machine can also effectively improve the energy utilization rate.

[0033] In the above technical solution, most of the heat generated by the refrigeration assembly is transferred to the hot water tank 200 through the cooling water in the circulation pipeline 440, thereby playing a preheating function on the room temperature water in the hot water tank 200, and reducing energy waste. When the user takes higher temperature hot water, the preheated water is heated twice to provide the user with a larger flow rate of water, which can meet the user's needs. Only a small part of the heat of the heat dissipation assembly 300 is dissipated into the air, and a fan is not needed for active heat dissipation, which can also ensure the normal operation of the refrigeration assembly.

[0034] Preferably, the refrigeration assembly can comprise a semiconductor refrigerator. Semiconductor refrigerators do not require the use of refrigerants, are more environmentally friendly, have no moving parts on them, are more resistant to shock, and have a longer life. When in operation, semiconductor refrigerators produce almost no noise. Optionally, the volume of the hot water tank 200 can be twice the volume of the cold water chamber. This allows the temperature of the water in the hot water tank 200 to not rise too high as the temperature of the cold water in the cold water chamber gradually decreases, thereby allowing the refrigeration assembly to continue to cool the water to the desired temperature for the user. Optionally, the hot water tank 200 can also be larger or smaller than the cold water chamber.

[0035] For a refrigeration assembly employing a compressor with a refrigerant circulation line 440, in this case, the heat dissipation assembly 300 can be configured as a pipe nested within another pipe, one of the refrigerant and the cooling water flows in the inner pipe of the heat dissipation assembly 300, and the other flows between the outer wall of the inner pipe and the outer pipe. The outer wall of the heat dissipation assembly 300 can also be provided with fins for passive heat dissipation through air. Optionally, the heat dissipation assembly 300 can comprise a metal heat sink provided with fins on one side or on both sides, and the refrigerant circulation line 440 and the circulation line 440 are alternately embedded in the gaps between the fins. Optionally, the heat dissipation assembly 300 can comprise a metal heat sink provided with fins on both sides, and the refrigerant circulation line 440 is embedded in the gaps between the fins on one side, and the circulation line 440 is embedded in the gaps between the fins on the other side.

[0036] A semiconductor refrigerator is usually configured in a sheet shape, thereby having a flat heating end and a refrigeration end. The refrigeration end can be pasted with a cooling fin, which comprises a base plate 310 pasted to the flat surface of the refrigeration end of the semiconductor refrigerator, and fins extending from the base plate 310 into the cold water chamber, so that the contact area of the cooling fin with water is increased. For a refrigeration assembly employing a semiconductor refrigerator, such as Figure 3As shown, the heat dissipation assembly 300 includes a substrate 310 and a plurality of heat dissipation fins 320 disposed on a first surface of the substrate 310, and a second surface of the substrate 310 opposite to the first surface is attached to the hot end. At least a portion of the circulation pipeline 440 is embedded into the gaps between the plurality of heat dissipation fins 320, and the surface of the circulation pipeline 440 is attached to the plurality of heat dissipation fins 320 and / or the substrate 310. Similar to the heat sink described above, the flat surface of the substrate 310 of the heat dissipation assembly 300 can be attached to the heat generating end of the semiconductor refrigerator, and the gaps can be filled with a material such as thermal conductive glue. The plurality of heat dissipation fins 320 can increase the contact area with air and improve the effect of passive heat dissipation. At the same time, the plurality of heat dissipation fins 320 also increase the contact area of the heat dissipation assembly 300 with the circulation pipeline 440, which can more efficiently conduct heat to the cooling water in the circulation pipeline 440. To further improve the efficiency of heat exchange, the portion of the circulation pipeline 440 embedded between the heat dissipation fins 320 can also be filled with thermal conductive glue. Alternatively, this portion of the circulation pipeline 440 can be connected to the substrate 310 and the heat dissipation fins 320 of the heat dissipation assembly 300 by brazing, laser welding, or the like. Alternatively, the portion of the circulation pipeline 440 embedded between the heat dissipation fins 320 can be flattened to some extent to increase the contact area with the heat dissipation fins 320. In summary, the heat dissipation assembly 300 thus arranged is more suitable for the semiconductor refrigerator and can more efficiently transfer most of the heat to the cooling water in the circulation pipeline 440 and a small part of the heat to the air.

[0037] As an example, at least a portion of the circulation pipeline 440 includes a plurality of straight pipe segments 442 and a plurality of elbow pipe segments 443 arranged alternately and connected to each other, and the plurality of straight pipe segments 442 are respectively embedded into a plurality of gaps between the plurality of heat dissipation fins 320. Since the area of the heat dissipation assembly 300 is relatively large and can be provided with a plurality of heat dissipation fins 320, the diameter of the circulation pipeline 440 is small, which can pass through the heat dissipation assembly 300 multiple times and take away a part of heat each time. This enables the cooling water circulating through the heat dissipation assembly 300 to take away enough heat, so that the circulation pump 441 pumping the same volume of cooling water can have a better cooling effect and improve the efficiency of the circulation pump 441.

[0038] As an example, the plurality of heat dissipation fins 320 protrude from at least a portion of the circulation pipeline 440 in a direction away from the first surface of the substrate 310. This can have a large enough contact area with air, thereby also making the passive air cooling effect of the heat dissipation assembly 300 better. After long-term use, even if the circulation pipeline 440 moves towards the direction in which the heat dissipation fins 320 protrude due to vibration or the like, it will not fall off the heat dissipation assembly 300.

[0039] Reference Figure 2To avoid the water purifier to be started every time the user takes water, the embedded pipeline machine also includes a cold water tank 600, which is connected in series on the cold tank water supplement pipeline 410. In this way, when the user takes cold water, the water to be refrigerated can be obtained from the cold water tank 600 first, and the water source is obtained from the water purifier only when the water level in the cold water tank 600 is low, thereby prolonging the service life of the water purifier. The embedded pipeline machine also includes a cold water pump 412, which is connected in series on the cold tank water supplement pipeline 410 between the cold water tank 600 and the cold tank 100. The cold water pump 412 can pump cold water to a height above the cold water cavity or above the liquid level of the cold water tank 600, which can effectively increase the water flow and improve the user experience.

[0040] The pipeline machine also includes a water inlet control valve 421, and the cold tank water supplement pipeline 410 and the hot water supplement pipeline 420 are connected to the total water inlet 10 via the water inlet control valve 421. The hot water tank 200 includes a first water level lower limit detection assembly 210 for detecting whether the water level in the hot water tank 200 is lower than the hot water lower limit. The first water level lower limit detection assembly 210 can include an ultrasonic liquid level sensor, an infrared liquid level sensor, a float switch, etc. The water level lower limit detection assembly can be at least partially disposed in the hot water tank 200, or can be disposed outside the hot water tank 200. Optionally, the first water level lower limit detection assembly 210 can also detect the upper limit of the water level in the hot water tank 200 as the first water level upper limit detection assembly 220 mentioned below. The opening condition of the water inlet control valve 421 includes that the water level in the hot water tank 200 is lower than the hot water lower limit. Thus, when the water level in the hot water tank 200 is too low, it can be supplemented in time. Optionally, when the water level in the hot water tank 200 reaches the hot water lower limit, there can still be a certain amount of water for the circulation pipeline 440 to circulate and dissipate heat.

[0041] The water inlet of the hot water tank 200 is connected with a first float switch 230, which closes the water inlet of the hot water tank 200 when the water level in the hot water tank 200 reaches the first hot water upper limit. The first float switch 230 can be disposed in the hot water tank 200 to detect the liquid level of the hot water tank 200. In the embodiment provided with the first float ball, the water inlet control valve 421 can still be opened when the liquid level of the hot water tank 200 reaches the first hot water upper limit, and only the water path is cut off by the float switch to prevent water overflow.

[0042] In the embodiment in which the inline water purifier comprises the cold water tank 600, the inline water purifier can further comprise a second water level lower limit detecting assembly 610. The second water level lower limit detecting assembly 610 is configured to detect whether the water level in the cold water tank 600 is lower than the cold water level lower limit. Optionally, the second water level lower limit detecting assembly 610 can comprise the same components as the first water level lower limit detecting assembly 210. In this case, the opening condition of the water inlet control valve 421 further comprises that the water level in the cold water tank 600 is lower than the cold water level lower limit. Specifically, the water inlet control valve 421 is opened for water replenishment as long as the water level in the hot water tank 200 is lower than the hot water level lower limit, or the water level in the cold water tank 600 is lower than the cold water level lower limit. In this way, the situation that one of the hot water tank 200 and the cold water tank 600 is already empty but the water inlet control valve 421 is not opened for water replenishment can be avoided.

[0043] For example, the water inlet of the cold water tank 600 is connected with a second float switch 630, which closes the water inlet of the cold water tank 600 when the water level in the cold water tank 600 reaches the first cold water level upper limit. As described above, the cold water tank 600 and the hot water tank 200 can be replenished simultaneously or non-simultaneously. This can be caused by the different amounts and frequencies of the user's taking hot water and cold water. In the case that the hot water tank 200 is already full of water while the cold water tank 600 is still being replenished, the hot water tank 200 is prevented from overflowing by the first float switch 230. Similarly, in the case that the cold water tank 600 is full of water while the hot water tank 200 is still being replenished, the second float switch 630 can prevent the water in the cold water tank 600 from overflowing.

[0044] For example, the hot water tank 200 further comprises a first water level upper limit detecting assembly 220 configured to detect whether the water level in the hot water tank 200 is higher than a second hot water level upper limit, and the cold water tank 600 further comprises a second water level upper limit detecting assembly 620 configured to detect whether the water level in the cold water tank 600 is higher than a second cold water level upper limit. In this case, the closing condition of the water inlet control valve 421 comprises that the water level in the hot water tank 200 is higher than the second hot water level upper limit, and the water level in the cold water tank 600 is higher than the second cold water level upper limit. As described above, because the cold water tank 600 and the hot water tank 200 can not be replenished simultaneously, the water inlet control valve 421 should not be closed to stop the replenishment of the other tank when one of the tanks is full of water. When the hot water tank 200 and the cold water tank 600 are both full of water, the water level information from the first water level upper limit detecting assembly 220 and the second water level upper limit detecting assembly 620 can be used to determine that the water replenishment is not needed and thus the water inlet control valve 421 is closed. In this way, the situation that the water replenishment from the water purifier is started as soon as the water level drops to the opening position of the float switch can be avoided. In this way, the start-stop frequency of the water purifier can be reduced, and the service life of the water purifier can be prolonged.

[0045] As mentioned above, the water inlet of the hot water tank 200 can be connected with the first ball float switch 230. Exemplarily, the first hot water upper limit is not lower than the second hot water upper limit. This can ensure that the water level in the hot water tank 200 can be replenished to the second water upper limit, and will not be unable to reach the second water upper limit because the first ball float switch 230 is closed. Exemplarily, the first cold water upper limit of the second ball float switch 630 connected to the water inlet of the cold water tank 600 is also not lower than the second cold water upper limit. Thus, when replenishing water, three situations can occur: 1) the water level of the hot water tank 200 reaches the second hot water upper limit, and the water level of the cold water tank 600 reaches the second cold water upper limit, and the first ball float switch 230 and the second ball float switch 630 are not closed, and the water inlet control valve 421 is cut off. 2) the water level of the hot water tank 200 reaches the first hot water upper limit, the first ball float switch 230 is closed, and the water level of the cold water tank 600 reaches the second cold water upper limit. 3) the water level of the hot water tank 200 reaches the second hot water upper limit, the water level of the cold water tank 600 reaches the first cold water upper limit, and the second ball float switch 630 is closed. In summary, the hot water tank 200 and the cold water tank 600 can be filled at the same time, and the water inlet control valve 421 is closed to prevent the water inlet from the water purifier once the water level is lowered to the opening position of the ball float switch. Thus, the start-stop frequency of the water purifier is reduced, and the service life is prolonged.

[0046] Exemplarily, the cold tank water replenishing pipeline 410 can be connected to the first predetermined position of the hot water replenishing pipeline 420, and the cold tank water replenishing pipeline 410 is connected to the total water inlet 10 through the hot water replenishing pipeline 420 upstream of the first predetermined position. The first predetermined position is located downstream of the water inlet control valve 421. When the water inlet control valve 421 is closed, the water source of the hot water replenishing pipeline 420 and the cold tank water replenishing pipeline 410 can be cut off at the same time. The water outlet of the circulating pipeline 440 is connected to the second predetermined position of the hot water replenishing pipeline 420, and the water inlet of the circulating pipeline 440 is connected to the water outlet of the hot water tank 200. In this way, an additional water inlet does not need to be opened on the hot water tank 200, which simplifies the process of the hot water tank 200, reduces the cost, and reduces the possible leakage points of the hot water tank 200. The second predetermined position is located downstream of the first predetermined position, and the hot water replenishing pipeline 420 is connected in series with the first one-way valve 422, and the first one-way valve 422 is located between the first predetermined position and the second predetermined position. The circulating pipeline 440 is also connected in series with the second one-way valve 423, and the water inlet control valve 421 is closed when the circulating water pump is turned on. Continue to refer to Figure 2When the hot water tank 200 is being filled, if the water inlet control valve 421 is open, when the circulating pump 441 pumps water from the hot water tank 200 into the circulation line 440, the total water inlet 10 will continue to fill the hot water tank 200, causing the first ball float switch 230 to close. In this case, the water in the circulation line 440 will not be able to return to the hot water tank 200 through the closed first ball float switch 230. In the case where the water inlet control valve 421 is closed, even if the water level in the hot water tank 200 reaches the first upper water level limit, when the circulating pump 441 is working, the water level in the hot water tank 200 will drop slightly, and the water flowing back from the circulation line 440 can return to the hot water tank 200 through the first ball float valve. Alternatively, a portion of the circulation line 440 can be connected by a non-pressure hose, for example, a hose connected to the circulation pump 441. This can facilitate installation and reduce costs, and can meet the use requirements. The first one-way valve 422 can only allow water in the circulation line 440 to flow back to the hot water tank 200. In embodiments in which the circulation line 440 includes a non-pressure hose, when the hot water tank 200 and / or the cold water tank 600 are being filled, the water in the hot water tank 200 will not flow back into the circulation line 440, and the water in the hot water tank 200 will not flow back into the circulation line 440. The first one-way valve 422 can also prevent the water under pressure from flowing back into the circulation line 440. Alternatively, the circulation line 440 is also in communication with the outside through the hot water line 430, and the first one-way valve 422 can prevent water from flowing out of the total water outlet 20. The second one-way valve 423 can prevent hot water in the hot water tank 200 from flowing to the cold water tank 600 under the drive of the circulating pump 441, and can prevent the temperature of the water in the cold water tank 600 from rising.

[0047] Thus, the first one-way valve 422 can prevent the circulation line 440 from being under pressure, and can prevent water leakage when a hose is present. The first one-way valve 422 can also prevent water under pressure from flowing back into the circulation line 440 or back into the hot water tank 200, causing the hot water tank 200 to overflow. The second one-way valve 423 can prevent circulating cooling water from entering the cold water tank 600, affecting the temperature of the cold water. Closing the water inlet control valve 421 when the circulating pump 441 is on can prevent the hot water tank 200 from being overfilled, causing the first ball float switch 230 to close, and the circulating water to be unable to return to the hot water tank 200.
