Description

Technical Field

[0001] This application relates to the field of water purification technology, and in particular to high-flow-rate water purification systems. Background Technology

[0002] Water purifiers, widely used in homes and businesses, primarily function to filter and purify tap water or other water sources, effectively removing impurities, bacteria, viruses, heavy metals, and chemical pollutants, thus providing users with safer and healthier drinking water. Currently, heating technologies are mainly divided into two categories: instantaneous heating technology and storage heating technology. In the technological development of water purifiers, instantaneous water purifiers have gradually gained favor with users due to their unique advantages. These devices not only possess the traditional filtration function of water purifiers but also integrate heating, achieving a unified purification and heating function, providing users with instant and convenient hot water service, especially suitable for home environments with high hot water demand.

[0003] However, in the current market, purified water is only supplied after it reaches the set temperature at the outlet of the instant heating element. Although this technology improves the efficiency of hot water heating to a certain extent, when the heating temperature difference is too large, the water supply speed is slow and the water flow rate is small, which cannot guarantee the user's water demand. The hot water storage tank technology does not continuously produce hot water, and after the stored hot water is used up, it is necessary to wait for it to be reheated to the set temperature, and the temperature of the hot water is not adjustable. Utility Model Content

[0004] Therefore, it is necessary to provide a high-flow-rate water purification system that can supply large volumes of water, is highly efficient, and provides accurate water temperature to address the above problems.

[0005] A high-flow-rate water purification system includes:

[0006] A filtration assembly is used to filter the acquired raw water to obtain purified water;

[0007] A room temperature water tank, connected downstream of the filter assembly, is used to store the purified water;

[0008] The first water outlet path connects the ambient temperature water tank and the first water outlet to supply ambient temperature water; and

[0009] The second water outlet is arranged in parallel with the first water outlet and is connected between the ambient temperature water tank and the second water outlet. The second water outlet includes a heating branch and an insulation branch. The heating branch is used to heat the purified water and supply water to the second water outlet. The insulation branch is connected between the outlet and inlet of the heating branch and is used to store the heated purified water and supply water to the heating branch.

[0010] In one embodiment, the heating branch includes an instant heating element and a reversing valve, wherein the instant heating element is located downstream of the ambient temperature water tank, and the reversing valve is located downstream of the instant heating element.

[0011] In one embodiment, when the preset temperature is equal to the water storage temperature, the heat preservation branch is activated, and the instant heating element is selectively turned on.

[0012] In one embodiment, when the preset temperature is greater than the water storage temperature, the insulation branch and the heating branch work simultaneously, and the heating branch is not connected to the ambient temperature water tank, and the instant heating element is turned on.

[0013] In one embodiment, when the preset temperature is lower than the storage water temperature, the heat preservation branch selectively operates, and the heating branch is connected to the ambient temperature water tank. Water from the ambient temperature water tank passes through the instant heating element, which selectively activates heating.

[0014] In one embodiment, the reversing valve has a first valve outlet and a second valve outlet, the first valve outlet is connected to the second water outlet, the second valve outlet is connected to the inlet of the insulation branch, and the control component controls the first valve outlet and the second valve outlet to open selectively.

[0015] In one embodiment, the heat preservation branch includes a heat preservation water tank, the inlet of which is connected to the outlet of the reversing valve, and the outlet of which is connected to the inlet of the instant heating element.

[0016] In one embodiment, the water purification system further includes a control component, which is used to acquire a preset temperature of the second outlet and detect the water temperature of the insulated branch and determine the operating condition of the second outlet water path. Under a first operating condition, the control component controls at least the insulated branch to operate and supply water. Under a second operating condition, the control component controls at least the heating branch to operate and supply water. And / or, the control component is used to control the purified water to circulate between the heating branch and the insulated branch according to the water temperature.

[0017] In one embodiment, the water purification system includes at least one of a first water outlet pump located in the first water outlet path, a second water outlet pump located in the second water outlet path, and a third water outlet pump located in the insulated branch path.

[0018] In one embodiment, the water purification system includes an exhaust branch and an exhaust port, the exhaust branch being connected between the ambient temperature water tank and the exhaust port, and / or the exhaust branch being connected between the insulation branch and the exhaust port.

[0019] The aforementioned high-flow water purification system, through the second water outlet, incorporates a heating branch and an insulation branch, enabling the water circuit to simultaneously provide instant heating and water storage / insulation functions. The insulation branch connects to both ends of the heating branch, allowing for selection based on different operating conditions: either directly heating the outlet water or using water stored in the insulation branch for heating. Furthermore, the heating branch can also circulate heating to the insulation branch. By setting operating conditions, the temperature difference between the heated and outlet water is reduced, thus achieving a high-flow supply of ambient, warm, and hot water. This avoids the need to increase the flux of the reverse osmosis membrane, reducing the cost and noise of the water purification system. Attached Figure Description

[0030] See Figure 1 , Figure 1 The diagram shows a structural schematic of a high-flow water purification system 1 according to an embodiment of the present application. The high-flow water purification system 1 provided in an embodiment of the present application includes a filter component 100, a normal temperature water tank 200, a first water outlet 300, a second water outlet 400, and a control component 600.

[0031] A filter assembly 100 is used to filter the acquired raw water to obtain purified water. A room temperature water tank 200 is connected downstream of the filter assembly and is used to store the purified water. A first water outlet 300 is connected between the room temperature water tank 200 and the first water outlet 11 and is used to supply room temperature water. A second water outlet 400 is arranged in parallel with the first water outlet 300 and is connected between the room temperature water tank 200 and the second water outlet 12. The second water outlet 400 includes a heating branch 410 and an insulation branch 420. The heating branch 410 is used to heat the purified water and supply water to the second water outlet 12. The insulation branch 420 is connected between the outlet and inlet of the heating branch 410 and is used to store the heated purified water and supply water to the heating branch 410.

[0032] The aforementioned high-flow water purification system 1, through the second water outlet 400, is equipped with a heating branch 410 and an insulation branch 420, enabling the water circuit to simultaneously possess instant heating and water storage insulation functions. The insulation branch 420 is connected to both ends of the heating branch 410, allowing selection based on different operating conditions whether to directly heat the water or use the water stored in the insulation branch 420 for heating the water outlet. Furthermore, the heating branch 410 can also circulate and heat the insulation branch 420. By setting operating conditions, the temperature difference of the heated water outlet is reduced, thereby achieving a high-flow supply of room temperature water, warm water, and hot water. This avoids the need to increase the flux of the reverse osmosis membrane, reducing the cost and noise of the water purification system 1.

[0033] See Figure 2 , Figure 2This is a control flowchart of the control component 600 in one embodiment of this application. In one embodiment, the water purification system 1 includes the control component 600, which is used to acquire the preset temperature of the second water outlet 12, detect the water temperature stored in the heat-insulating branch 420, and determine the operating condition of the second water outlet 400. In a first operating condition, the control component 600 controls at least the heat-insulating branch 420 to operate and supply water. In a second operating condition, the control component 600 controls at least the heating branch 410 to operate and supply water.

[0034] The second water outlet 400 is used to supply warm or hot water. Specifically, the first operating condition is defined as follows: when the control component 600 determines that the preset temperature is greater than or equal to the stored water temperature, that is, when the user-set water intake temperature is greater than or equal to the stored water temperature, at least the insulation branch 420 operates, supplying water from the stored purified water to the second water outlet 12 or supplying water to the second water outlet 12 through the heating branch 410. Specifically, the second operating condition is defined as follows: when the control component 600 determines that the preset temperature is less than the stored water temperature, that is, when the user-set water intake temperature is less than the stored water temperature, at least the heating branch 410 operates, supplying water from the stored purified water to the second water outlet 12 through the heating branch 410 or supplying room temperature water to the second water outlet 12 through the heating branch 410.

[0035] In one embodiment, the heating branch 410 includes an instant heating element 411 and a reversing valve 412. The instant heating element 411 is located downstream of the ambient temperature water tank 200, and the reversing valve 412 is located downstream of the instant heating element 411. Specifically, the control component 600 controls the operation of the heating branch 410 mainly by controlling the start and stop of the instant heating element 411 and the reversing valve 412, and the control component 600 controls the operation of the insulation branch 420 mainly by controlling the water pump on the insulation branch 420.

[0036] Specifically, the reversing valve 412 is connected upstream to the instant heating element 411 and downstream to the second water outlet 12 and the insulation branch 420. The reversing valve 412 changes the water flow direction so that it flows back to the heating branch 410 through the insulation branch 420. The clean water flows through the instant heating element 411, and the water at the outlet of the heating element reaches the required preset temperature.

[0037] In one embodiment, when the first operating condition is that the preset temperature equals the water storage temperature, the control component 600 controls the heat preservation branch 420 to operate, and the control component 600 selectively controls the instant heating element 411 to turn on. At this time, the heating branch 410 is not connected to the ambient temperature water tank 200.

[0038] Specifically, temperature sensors are installed at both the inlet and outlet of the instant heating element 411. When the preset temperature equals the stored water temperature, and the difference between the inlet temperature of the instant heating element 411 and the preset temperature does not exceed the allowable range, the instant heating element 411 does not turn on, and water is supplied directly from the water stored in the insulation branch 420. When the preset temperature equals the stored water temperature, and the difference between the inlet temperature of the instant heating element 411 and the preset temperature exceeds the allowable range, the instant heating element 411 turns on, and the water stored in the insulation branch 420 is heated and supplied after reaching the allowable range at the outlet of the instant heating element 411. The difference between the inlet temperature of the instant heating element 411 and the preset temperature can be defined as ±2℃, that is, the inlet temperature of the instant heating element 411 equals the preset temperature or the stored water temperature ±2℃.

[0039] In one embodiment, when the first operating condition is that the preset temperature is greater than the water storage temperature, the control component 600 controls the heat preservation branch 420 and the heating branch 410 to work simultaneously, and the heating branch 410 is not connected to the ambient temperature water tank 200, and the control component 600 controls the instant heating element 411 to turn on.

[0040] Specifically, the insulation branch 420 and the heating branch 410 work simultaneously, that is, the heating element 411 is turned on to heat the water stored in the insulation branch 420 to reach the preset temperature and then supply water to the second outlet 12. The temperature difference between the stored water and the water intake is small, and the heating element has high working efficiency to achieve a large flow of water supply.

[0041] Understandably, in the first operating condition, the ambient temperature water tank 200 does not supply water to the second water outlet 400, but only to the first water outlet 300.

[0042] In one embodiment, when the second operating condition is that the preset temperature is lower than the water storage temperature, the control component 600 controls the heat preservation branch 420 to work selectively, and the heating branch 410 is connected to the ambient temperature water tank 200. Water from the ambient temperature water tank 200 passes through the instant heating element 411, and the control component 600 controls the instant heating element 411 to selectively turn on heating.

[0043] Specifically, the insulation branch 420 and the heating branch 410 can operate simultaneously, or only the heating branch 410 can operate. When the heating branch 410 is operating, it maintains constant communication with the ambient temperature water tank 200. When the instantaneous heating element 411 is turned on, it heats the water stored in the insulation branch 420, the ambient temperature water supplied by the ambient temperature water tank 200, or a mixture of both, to reach a preset temperature before supplying water to the second outlet 12. Furthermore, the water supplied to the instantaneous heating element 411 can be water stored in the insulation branch 420, water stored in the ambient temperature water tank 200, or a mixture of both. Regardless of the type of water supply, when the preset temperature is lower than the temperature of the stored water, the temperature difference heated by the heating element is small, the heating element operates efficiently, and a large flow rate of water can be achieved.

[0044] In one embodiment, the reversing valve 412 is provided with a first valve outlet and a second valve outlet. The first valve outlet is connected to the second water outlet 12, and the second valve outlet is connected to the inlet of the insulation branch 420. The control component 600 controls the first valve outlet and the second valve outlet to open selectively.

[0045] Specifically, when the user is not drawing water, the second valve outlet is open, storing water in the insulated branch 420. Once the water level reaches its maximum, the second valve outlet closes. When the user draws water, and the first operating condition is that the preset temperature equals the stored water temperature, the second valve outlet closes, meaning the heating element 411 selectively opens, and the first valve outlet opens to supply water. When the user draws water, and the first operating condition is that the preset temperature is higher than the stored water temperature, the second valve outlet closes, meaning the heating element 411 opens, and the first valve outlet opens to supply water. When the user draws water, and the second operating condition is that the preset temperature is lower than the stored water temperature, the second valve outlet closes, meaning the heating element 411 opens, the ambient temperature water tank 200 selectively connects to the heating branch 410, and the first valve outlet opens to supply water.

[0046] Furthermore, when the water level in the insulated branch 420 reaches the lower limit, the outlet of the first valve closes and the outlet of the second valve opens, allowing water to be stored in the insulated branch 420.

[0047] In one embodiment, the heat preservation branch 420 includes a heat preservation water tank 421, the inlet of which is connected to the outlet of the reversing valve 412, and the outlet of which is connected to the inlet of the instant heating element 411.

[0048] Specifically, the inlet of the insulated water tank 421 is connected to the second valve outlet of the reversing valve 412. The outlet of the insulated water tank 421 and the outlet of the ambient temperature water tank 200 are both connected to the inlet of the instant heating element 411 through pipelines. A valve is provided at the junction of the pipeline of the outlet of the insulated water tank 421 and the pipeline of the outlet of the ambient temperature water tank 200. The valve is selectively opened under the control of the control component 600 according to the first working condition or the second working condition.

[0049] Furthermore, the insulated water tank 421 is equipped with a lower limit water level sensor and an upper limit water level sensor. The control component 600 is electrically connected to the lower limit water level sensor and the upper limit water level sensor, and determines the water storage based on the signals fed back by the sensors.

[0050] In one embodiment, the control component 600 is used to control the circulation of purified water between the heating branch 410 and the insulation branch 420 according to the water storage temperature. Specifically, if the user does not use water for a long time or the ambient temperature is low, the water storage temperature of the insulation water tank 421 drops significantly below the storage temperature. In this case, the control component 600 controls the second valve outlet to open and controls the instant heating element 411 to turn on, so that the purified water circulates between the heating branch 410 and the insulation branch 420 to bring the stored water back to the storage temperature.

[0051] In one embodiment, the filter assembly 100 includes a fine filter, a pre-filter, and a post-filter that are partially or completely combined, or the filter module includes a fine filter, a pre-filter, or a post-filter that are separately configured.

[0052] Specifically, the fine filter element can be an RO (Reverse Osmosis) filter element, a nanofiltration filter element, or others. Raw water is filtered through the fine filter element to form purified water. The filter module includes at least one individual or composite fine filter element. When the filter module includes a pre-filter and a fine filter element, the raw water is filtered through the pre-filter and fine filter elements sequentially to form purified water. When the filter module includes a post-filter and a fine filter element, the raw water is filtered through the fine filter and post-filter elements sequentially to form purified water. When the filter module includes a pre-filter, a post-filter, and a fine filter element, the raw water is filtered through the pre-filter, fine filter, and post-filter elements sequentially to form purified water.

[0053] Understandably, the temperature of room temperature water is basically the same as the temperature of the raw water. The temperature of the warm or hot water in the second water outlet (400) is higher than the room temperature water temperature.

[0054] In one embodiment, the ambient temperature water tank 200 has two outlets, one of which is connected to the second water outlet 400 via a pipe, and the other is connected to the first water outlet 11 via a pipe, i.e., connected to the first water outlet 300. The second water outlet 12 and the first water outlet 11 are set independently, and the first water outlet 11 is only used to supply ambient temperature water.

[0055] In other embodiments, the second outlet 12 and the first outlet 11 are the same outlet, and the control component 600 controls the supply of either room temperature water or warm water.

[0056] In one embodiment, the water purification system 1 includes at least one of a first water outlet pump 301 disposed in the first water outlet passage 300, a second water outlet pump 401 disposed in the second water outlet passage 400, and a third water outlet pump 422 disposed in the heat preservation branch passage 420.

[0057] Specifically, the first outlet pump 301, under the control of the control component 600, draws room temperature water from the room temperature water tank 200 and supplies water to the second outlet 12. The second outlet pump 401, located on the upstream pipe of the heating branch 410 and the insulation branch 420, is also under the control of the control component 600 and draws room temperature water from the room temperature water tank 200 to supply water to the heating branch 410. The third outlet pump 422, under the control of the control component 600, draws water from the insulation water tank 421 and supplies water to the heating branch 410.

[0058] In one embodiment, the water purification system 1 includes an exhaust branch 500 and an exhaust port. The exhaust branch 500 is connected between the ambient temperature water tank 200 and the exhaust port, and / or, the exhaust branch 500 is connected between the insulation branch 420 and the exhaust port. Specifically, the exhaust branch 500 has two branches, one for exhausting gas from the ambient temperature water tank 200 and the other for exhausting gas from the insulation water tank 421. The two branches converge and connect to the exhaust port.

[0059] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0060] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
