Description

Technical Field

[0002] In the context of the big health industry, household water purifier consumption continues to expand the boundaries of product value based on water quality safety requirements, and product functions are gradually moving from safety to health and comfort. In addition to pure water products, there are also products with rich product functions. Among them, the concept of boiled water (i.e. cooked water) is deeply rooted in the hearts of Chinese people and may become the next selling point for water purification. Some manufacturers have focused on the cooked water preparation system and designed a cooked water preparation system that introduces a heat exchanger to achieve instant boiling and physical cooling to prepare cooked water at all temperatures. However, the heat of the newly added heat exchanger itself and the water stored in the pipeline can easily cause the water temperature in the front section of the water pipe to be at room temperature after the user has not used hot water for a long time, making the temperature of the first cup of boiling water often inaccurate, and the amount of cold water is large, affecting the user experience. Summary of the invention

[0030] Refer to FIG1 , which is a schematic diagram of the structure of a water purifier provided by an embodiment of the present invention. The water purifier provided by an embodiment of the present invention includes a water storage module 100, a heating module 200 and a water outlet module 300; the water storage module 100 includes a pure water tank 110, and the pure water tank 110 is used to store pure water; the heating module 200 includes a first heating element 210, a second heating element 220 and a heat exchange element 230, and the heat exchange element 230 includes a first heat exchange pipeline 231 and a second heat exchange pipeline 232 for mutual heat exchange, and the water inlet of the first heating element 210 is connected to the pure water tank 110. 0, the water outlet of the first heating element 210 is used to communicate with the water inlet of the first heat exchange pipeline 231, the water inlet of the second heating element 220 is connected to the water outlet of the first heat exchange pipeline 231, and the water outlet of the second heating element 220 is connected to the water inlet of the second heat exchange pipeline 232; the water inlet of the water outlet module 300 is used to communicate with the water outlet of the first heating element 210 and the water outlet of the second heat exchange pipeline 232, and the water outlet of the water outlet module 300 is used for drainage.

[0031] Specifically, in the present application, the water outlet of the first heating element 210 is connected to the water inlet of the first heat exchange pipeline 231, so that the first heating element 210 can introduce the heated boiling water into the first heat exchange pipeline 231, and through the heat exchange between the first heat exchange pipeline 231 and the second heat exchange pipeline 232, the cooked water preparation of the full temperature section can be achieved by boiling and physically cooling down, and the water outlet temperature of the water outlet module 300 is controlled by the cooperation of the first heating element 210 and the second heating element 220. Among them, since the water inlet of the water outlet module 300 can also be connected to the water outlet of the first heating element 210, the length of the pipeline between the first heating element 210 and the water outlet module 300 is shortened. When obtaining the first cup of boiling water, the boiling water heated by the first heating element 210 can be directly discharged from the water outlet module 300, thereby reducing the interference of cold water in the pipeline, ensuring the water outlet temperature of the first cup of boiling water, and improving the reliability of the water purifier.

[0032] It should be noted that, in the case of not the first cup of boiling water, that is, in the case of taking general boiling water, the boiling water heated by the first heating element 210 can be directly discharged from the water outlet module 300, thereby reducing the process of obtaining cooked water by heat exchange and heating by the second heating element 220, avoiding energy waste. Among them, in the case of not the first cup of boiling water, since the pipeline between the water outlet of the first heating element 210 and the water inlet of the water outlet module 300 is hot water, it will not affect the outlet water temperature flowing toward the water outlet module 300 through the water outlet of the first heating element 210, so the power of the first heating element 210 in the case of not the first cup of boiling water can be lower than the power of the first heating element 210 in the case of taking the first cup of boiling water.

[0033] Referring to Figure 1, in one embodiment, the water purifier also includes a first control valve 240, which is arranged on the pipeline between the water outlet of the first heating element 210 and the water inlet of the first heat exchange pipeline 231. The water inlet of the first control valve 240 is connected with the water outlet of the first heating element 210, and the two water outlets of the first control valve 240 are respectively used to communicate with the water inlet of the first heat exchange pipeline 231 and the water inlet of the water outlet module 300. The first control valve 240 is used to control the connection and disconnection between the water outlet of the first heating element 210 and the water inlet of the first heat exchange pipeline 231 and the connection and disconnection between the water outlet of the first heating element 210 and the water outlet module 300.

[0034] Specifically, when boiling water is needed, the first control valve 240 controls the water outlet of the first heating element 210 to be connected to the water outlet module 300, so that the boiling water heated by the first heating element 210 flows directly toward the water outlet module 300, thereby ensuring the outlet water temperature of the first cup of boiling water while avoiding energy waste for water other than the first cup of boiling water.

[0035] When low-temperature hot water (higher than normal temperature) is needed, the first control valve 240 controls the water outlet of the first heating element 210 to be connected with the water inlet of the first heat exchange pipeline 231, so that the boiling water heated by the first heating element 210 flows directly toward the first heat exchange pipeline 231, and exchanges heat with the second heat exchange pipeline 232, so that cooked water flows out of the water outlet of the first heat exchange pipeline 231, and then flows through the second heating element 220, and then obtains heat through the heat exchange of the second heat exchange pipeline 232, so that the water outlet of the second heat exchange pipeline 232 flows out low-temperature water toward the water outlet module 300. When high-temperature hot water (lower than boiling water) is required, the first control valve 240 controls the water outlet of the first heating element 210 to be connected with the water inlet of the first heat exchange pipeline 231, so that the boiling water heated by the first heating element 210 flows directly toward the first heat exchange pipeline 231, and exchanges heat with the second heat exchange pipeline 232, so that the water outlet of the first heat exchange pipeline 231 flows out cooked water, and then flows through the second heating element 220, is heated by the second heating element 220, and then obtains heat through the heat exchange of the second heat exchange pipeline 232, so that the water outlet of the second heat exchange pipeline 232 flows out high-temperature hot water toward the water outlet module 300. That is, when low-temperature hot water is required, only the first heating element 210 generates heat, and when high-temperature hot water is required, both the first heating element and the second heating element generate heat.

[0036] Referring to Figure 1, in one embodiment, a first temperature detecting element 250 is provided on the pipeline between the water outlet of the first heating element 210 and the water inlet of the first control valve 240, and the first temperature detecting element 250 is used to detect the outlet water temperature of the water outlet of the first heating element 210; and / or, a second temperature detecting element 260 is provided on the pipeline between the water outlet of the second heating element 220 and the water inlet of the second heat exchange pipeline 232, and the second temperature detecting element 260 is used to detect the outlet water temperature of the water outlet of the second heating element 220.

[0037] Specifically, the water purifier also includes a controller, which is electrically connected to the first temperature detection member 250, the second temperature detection member 260, the first heating member 210, the second heating member 220 and the first control valve 240. The first temperature detection member 250 is used to measure the water outlet temperature of the water outlet of the first heating member 210, and send the first temperature information to the controller, and the second temperature detection member 260 is used to measure the water outlet temperature of the water outlet of the second heating member 220, and send the second temperature information to the controller. The controller controls the operation of the first control valve 240, the heating power of the first heating member 210 and the second heating member 220, and then receives the first temperature information and the second temperature information. It can control the working state of each component according to the temperature and water volume set by the user, thereby meeting the user's needs and realizing the intelligence of the water purifier. Preferably, the first temperature detection member 250 and the second temperature detection member 260 are temperature sensing bags.

[0038] Referring to Figure 1, in one embodiment, the water purifier also includes a second control valve 420 and a first water pump 410, the water inlet of the first water pump 410 is connected to the water outlet of the pure water tank 110, the water outlet of the first water pump 410 is connected to the water inlet of the water outlet module 300, and the second control valve 420 is arranged on the pipeline between the water outlet of the first water pump 410 and the water inlet of the water outlet module 300, and the second control valve 420 is used to control the connection and disconnection of the water outlet of the first water pump 410 and the water inlet of the water outlet module 300.

[0039] Specifically, the water inlet of the second control valve 420 is connected to the water outlet of the first water pump 410, and the water outlet of the second control valve 420 is connected to the water inlet of the water outlet module 300. When the second control valve 420 controls the water outlet of the first water pump 410 to be connected to the water inlet of the water outlet module 300, the normal temperature water in the pure water tank 110 can be obtained from the water outlet of the water outlet module 300, thereby improving the adaptability of the water purifier. The second control valve 420 is electrically connected to the controller, and the controller is used to control the opening and closing of the second control valve 420.

[0040] Referring to Figure 1, in one embodiment, the first water pump 410 is arranged on the pipeline between the water inlet of the first heating element 210 and the water outlet of the pure water tank 110, and the water purifier also includes a first check valve 430, which is arranged on the pipeline between the water outlet of the first water pump 410 and the water inlet of the first heating element 210. The water inlet of the second control valve 420 is connected to the pipeline between the water outlet of the first water pump 410 and the water inlet of the first check valve 430, so that when the controller controls the second control valve 420 to open, so that the water outlet of the second water pump 160 is connected to the water inlet of the second control valve 420, it can prevent the hot water heated by the first heating element 210 from flowing back to the water inlet of the second control valve 420, thereby ensuring the water outlet temperature of the water outlet of the second control valve 420 and improving the reliability of the water purifier.

[0041] Referring to Figure 1, in one embodiment, the water storage module 100 also includes a raw water tank 120 and a filter element 150. The raw water tank 120 is used to communicate with an external water source. The water inlet of the filter element 150 is connected to the water outlet of the raw water tank 120, and a second water pump 160 is provided on the pipeline between the water inlet of the filter element 150 and the water outlet of the raw water tank 120. The clean water outlet of the filter element 150 is connected to the water inlet of the pure water tank 110. The filter element 150 is used to purify the water flowing into the pure water tank 110 through the raw water tank 120.

[0042] Specifically, the second water pump 160 is electrically connected to the controller, and the controller is used to control the operation of the second water pump 160 so that the water source in the raw water tank 120 flows into the pure water tank 110 after being purified by the filter element 150, thereby effectively improving the user's drinking water safety and improving the reliability of the water purifier.

[0043] Furthermore, the water storage module 100 further includes a first water inlet valve 170, which is disposed on a pipeline between the water inlet of the second water pump 160 and the water outlet of the raw water tank 120, and is used to control the on-off between the water outlet of the raw water tank 120 and the water inlet of the second water pump 160. The first water inlet valve 170 is electrically connected to a controller, and the controller is used to control the opening and closing of the first water inlet valve 170.

[0044] Referring to FIG. 1 , in one embodiment, the water storage module 100 further includes a wastewater tank 130 , the water inlet of the wastewater tank 130 is connected to the wastewater outlet of the filter element 150 to collect concentrated water generated during the water purification process, so as to realize concentrated water recovery.

[0045] Furthermore, the water storage module 100 further includes a wastewater valve 180, which is disposed on a pipeline between the water inlet of the wastewater tank 130 and the wastewater outlet of the filter element 150, and is used to control the on-off between the water inlet of the wastewater tank 130 and the wastewater outlet of the filter element 150. The wastewater valve 180 is electrically connected to a controller, and the controller is used to control the opening and closing of the wastewater valve 180.

[0046] Referring to Figure 1, in one embodiment, the water storage module 100 also includes a water storage tank 140 and a partition 141. The partition 141 is accommodated in the water storage tank 140 and connected to the box wall of the water storage tank 140 to separate the water storage tank 140 into a first box body and a second box body. The height of the partition 141 is lower than the height of the box wall of the water storage tank 140 so that the upper ends of the first box body and the second box body are connected, wherein the first box body is configured as a raw water tank 120, and the second box body is configured as a waste water tank 130.

[0047] Specifically, the bottom wall of the partition 141 is connected to the bottom of the water storage tank 140, and the side wall of the partition 141 is connected to the wall of the water storage tank 140, thereby dividing the water storage tank 140 into a first box body and a second box body, which are independent at the lower end and connected at the upper end. When the raw water tank 120 is injected with external water, the liquid level of the water source in the raw water tank 120 will exceed the partition 141, so that the waste water tank 130 is also filled with water, that is, the waste water tank 130 is connected with the water source in the raw water tank 120. When the controller controls the second water pump 160 to operate so that part of the water in the raw water tank 120 flows into the filter element 150, the concentrated water generated by the filter element 150 during the water purification process will enter the waste water tank 130 through the pipeline. Since the height of the water source in the water storage tank 140 is higher than the height of the partition 141, the concentrated water will be mixed and diluted with the water in the raw water tank 120 and enter the filter element 150 again, so that the concentrated water can be utilized and the water production rate can be improved.

[0048] Among them, when a part of the water source in the raw water tank 120 is consumed so that the liquid level of the water source in the raw water tank 120 is lower than the height of the partition 141, the liquid level of the water source in the waste water tank 130 is level with the height of the partition 141, and when the concentrated water is discharged to the waste water tank 130 during the water purification process of the filter element 150, the concentrated water will be mixed and diluted with the water source in the waste water tank 130, and the mixed and diluted water source will overflow into the raw water tank 120 through the partition 141, and be mixed and diluted with the water source in the raw water tank 120, and flow into the filter element 150 through the water outlet of the raw water tank 120 for utilization. Among them, when the water volume in the raw water tank 120 becomes smaller and smaller, and the concentrated water discharged during the water purification process of the filter element 150 becomes more and more, making the concentrated water content in the wastewater tank 130 higher and higher, the setting of the partition 141 can retain the water source with higher concentrated water concentration in the wastewater tank 130, so that the water source flowing into the raw water tank 120 is the water source after the water source in the wastewater tank 130 is mixed with the concentrated water and diluted, thereby avoiding the direct filtering and utilization of high-concentration concentrated water, reducing energy waste, and increasing the service life of the filter element 150.

[0049] Referring to FIG. 1 , in one embodiment, the water storage module 100 further includes a water level detection member 190 . The water level detection member 190 is disposed in the raw water tank 120 and is located at the lower end of the raw water tank 120 .

[0050] Specifically, the water level detection member 190 is connected to the wall of the raw water tank 120 and is electrically connected to the controller, and the height of the installation position of the water level detection member 190 is lower than the height of the partition 141. The water level detection member 190 is used to detect the height of the water level in the raw water tank 120 and send the water level information to the controller. When the water level in the raw water tank 120 is lower than the set value, the controller will prompt the user to change the water in the raw water tank 120. It should be noted that when the water level in the raw water tank 120 is low, when the water source overflowing from the waste water tank 130 through the partition 141 is mixed with the water source in the raw water tank 120, the dilution degree is poor, so that the concentration of the concentrated water in the raw water tank 120 is high, that is, the water quality of the water source is poor, and the water needs to be changed again.

[0051] Referring to FIG. 1 , in one embodiment, the water storage module 100 further includes a water quality detector, which is disposed in the raw water tank 120 and located at the lower end of the raw water tank 120. Specifically, the water quality detector is electrically connected to the controller, and the water quality detector is used to detect the water quality of the water source in the raw water tank 120 and send the water quality information to the controller. When the water quality in the raw water tank 120 is lower than the set value, the controller will prompt the user to change the water in the raw water tank 120.

[0052] Referring to Figure 1, in one embodiment, the water purifier also includes an ice-making module 500, which includes a cold water tank 510, an ice-making box 520 and an ice storage box 530. The water inlet of the cold water tank 510 is connected to the water outlet of the pure water tank 110, and a third water pump 550 is provided on the pipeline between the water inlet of the cold water tank 510 and the water outlet of the pure water tank 110. The water inlet of the ice-making box 520 is connected to the water outlet of the cold water tank 510 for making ice, and a fourth water pump 560 is provided on the pipeline between the water inlet of the ice-making box 520 and the water outlet of the cold water tank 510. The ice storage box 530 is arranged between the ice-making box 520 and the cold water tank 510, and the ice storage box 530 is used to store ice cubes made by the ice-making box 520.

[0053] Specifically, the ice storage box 530 is arranged between the ice making box 520 and the cold water tank 510. The ice cubes stored in the ice storage box 530 can cool the water in the cold water tank 510. Therefore, when the fourth water pump 560 delivers the water in the cold water tank 510 to the ice making box 520, the water temperature in the cold water tank 510 is reduced, which can improve the ice making efficiency of the ice making box 520, thereby improving the user experience.

[0054] Furthermore, the ice-making module 500 further includes a second water inlet valve 540, which is disposed on a pipeline between the water outlet of the fourth water pump 560 and the water inlet of the ice-making box 520, and the second water inlet valve 540 is used to control the on-off between the water outlet of the fourth water pump 560 and the water inlet of the ice-making box 520. The second water inlet valve 540 is electrically connected to a controller, and the controller is used to control the opening and closing of the second water inlet valve 540.

[0055] 1 , in one embodiment, the water outlet of the ice box 520 is used to communicate with the water inlet of the cold water tank 510 , and the water outlet of the fourth water pump 560 is used to communicate with the water inlet of the water outlet module 300 .

[0056] Specifically, the water in the ice box 520 that has not condensed into ice can flow back into the cold water tank 510 through the pipeline, thereby preventing the ice cubes from melting easily due to the presence of water in the ice box 520, and allowing the water outlet of the water outlet module 300 to discharge ice water, thereby improving the adaptability of the water purifier. Among them, since the temperature of the water drained from the ice box 520 to the cold water tank 510 is relatively low, the water is used to cool the normal temperature water in the cold water tank 510, thereby improving the cold capacity utilization rate and reducing the energy consumption of the ice box 520.

[0057] Furthermore, a drain valve 580 is provided between the pipe between the water outlet of the ice box 520 and the water inlet of the cold water tank 510, and the drain valve 580 is used to control the connection and disconnection between the water outlet of the ice box 520 and the water inlet of the cold water tank 510. The drain valve 580 is connected to a controller, and the controller is used to control the opening and closing of the drain valve 580.

[0058] Furthermore, the water purifier further includes a third water inlet valve 450, which is disposed on a pipeline between the water outlet of the fourth water pump 560 and the water inlet of the water outlet module 300, and the third water inlet valve 450 is used to control the on-off between the water outlet of the fourth water pump 560 and the water inlet of the water outlet module 300. The third water inlet valve 450 is connected to a controller, and the controller is used to control the opening and closing of the third water inlet valve 450.

[0059] 1 , in one embodiment, the water outlet of the cold water tank 510 is connected to the water inlet of the water storage module 100 , and a fifth water pump 570 is disposed on the pipeline between the water outlet of the cold water tank 510 and the water inlet of the water storage module 100 .

[0060] Specifically, the water outlet of the cold water tank 510 is connected to the water inlet of the water storage tank 140. When the water in the cold water tank 510 needs to be drained for cleaning, the fifth water pump 570 discharges the water into the water storage tank 140 through a pipeline for utilization, thereby improving the utilization rate of the water.

[0061] Furthermore, the water outlet of the cold water tank 510 is connected to the water inlet of the waste liquid tank, so that the ice water discharged from the cold water tank 510 can be mixed with the water source in the waste water tank 130 to cool down before flowing into the raw water tank 120, thereby avoiding the low water temperature flowing into the water inlet of the filter element 150 through the water outlet of the raw water tank 120, which affects the service life of the filter element 150.

[0062] Among them, a high water level detector and a low water level detector are provided in the cold water tank 510. When the water level in the cold water tank 510 is lower than the set value, water is pumped from the pure water tank 110 to the cold water tank 510 through the third water pump 550 to add water; when the water level is higher than the set value, the third water pump 550 stops pumping water.

[0063] Referring to FIG. 1 , in one embodiment, the water purifier further includes a second check valve 440, which is disposed on a pipeline between the water outlet of the fifth water pump 570 and the water inlet of the water storage module 100. The second check valve 440 is disposed on a pipeline between the water outlet of the fifth water pump 570 and the water inlet of the waste water tank 130, thereby preventing the water source in the waste water tank 130 from flowing back to the cold water tank 510 through the pipeline, thereby contaminating the water source in the cold water tank 510.
