Description

TECHNICAL FIELD

[0002] Under the background of the health industry, household water purifiers continue to expand the product value boundary on the basis of water quality safety requirements, and the product function gradually advances 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 hot boiled water (i.e. cooked water) is deeply rooted in the hearts of the Chinese people, or it will become the next selling point of water purification. Some manufacturers have focused on cooked water production systems and designed a cooked water production system that uses a heat exchanger to achieve instant boiling and physical cooling to prepare full-temperature cooked water. However, the heat of the newly added heat exchanger and the water in the pipeline can easily cause the water temperature in the front section of the water pipe to be room temperature after a long time without using hot water, making the temperature of the first cup of boiling water often inaccurate, and the amount of cold water is large, affecting the user experience.

[0030] Referring to Figure 1 , Figure 1 A structure diagram of a pure drinking machine is provided in an embodiment of the present application. The pure drinking machine provided in the embodiment of the present application comprises a water storage module 100, a heating module 200 and a water outlet module 300. The water storage module 100 comprises a pure water tank 110, which is used for storing pure water. The heating module 200 comprises a first heating element 210, a second heating element 220 and a heat exchange element 230. The heat exchange element 230 comprises first and second heat exchange pipelines 231 and 232, which exchange heat with each other. The water inlet of the first heating element 210 is in communication with the water outlet of the pure water tank 110. The water outlet of the first heating element 210 is used for being in communication with the water inlet of the first heat exchange pipeline 231. The water inlet of the second heating element 220 is in communication with the water outlet of the first heat exchange pipeline 231. The water outlet of the second heating element 220 is in communication with the water inlet of the second heat exchange pipeline 232. The water inlet of the water outlet module 300 is used for being in communication with the water outlet of the first heating element 210 and the water outlet of the second heat exchange pipeline 232. The water outlet of the water outlet module 300 is used for draining water.

[0031] Specifically, in the present application, the water outlet of the first heating element 210 is in communication with the water inlet of the first heat exchange pipeline 231, so that the first heating element 210 can guide the heated boiling water into the first heat exchange pipeline 231, and the heat exchange between the first and second heat exchange pipelines 231 and 232 is used to realize the preparation of full-temperature boiled water through the physical cooling and temperature reduction of the boiled water, and the cooperation between the first and second heating elements 210 and 220 is used to realize the control of the water outlet temperature of the water outlet module 300. Since the water inlet of the water outlet module 300 can also be in communication with 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, so that when the first cup of boiling water is obtained, the heated boiling water from the first heating element 210 can be directly drained by the water outlet module 300, thereby reducing the interference of cold water in the pipeline and ensuring the water outlet temperature of the first cup of boiling water, and improving the reliability of the pure drinking machine.

[0032] It should be noted that in the case of non-first cup of boiling water, i.e. in the case of general boiling water, the boiling water heated by the first heating member 210 can be directly discharged by the water outlet module 300, thereby reducing the process of heat exchange to obtain hot water and heating by the second heating member 220, and avoiding waste of energy. Among them, when the non-first cup of boiling water, since the pipeline between the water outlet of the first heating member 210 and the water inlet of the water outlet module 300 is hot water, it will not affect the temperature of the water outlet flowing out from the water outlet of the first heating member 210 towards the water outlet module 300, so the power of the first heating member 210 in the case of non-first cup of boiling water can be lower than the power of the first heating member 210 in the case of first cup of boiling water.

[0033] Referring to Figure 1 In one embodiment, the net drinking machine also includes a first control valve 240, which is arranged on the pipeline between the water outlet of the first heating member 210 and the water inlet of the first heat exchange pipeline 231. The water inlet of the first control valve 240 is in communication with the water outlet of the first heating member 210, and the two water outlets of the first control valve 240 are respectively in communication 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 on-off between the water outlet of the first heating member 210 and the water inlet of the first heat exchange pipeline 231 and the on-off between the water outlet of the first heating member 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 member 210 to communicate with the water outlet module 300, so that the boiling water heated by the first heating member 210 directly flows out towards the water outlet module 300, thereby ensuring the water temperature of the first cup of boiling water while avoiding energy waste when the non-first cup of boiling water.

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

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

[0037] Specifically, the pure drinking machine further comprises a controller, which is electrically connected with the first temperature detection element 250, the second temperature detection element 260, the first heating element 210, the second heating element 220, and the first control valve 240. The first temperature detection element 250 is used to measure the outlet temperature of the first heating element 210 and send the first temperature information to the controller, and the second temperature detection element 260 is used to measure the outlet temperature of the second heating element 220 and send the second temperature information to the controller. The controller can control the working state of each component according to the temperature and water volume set by the user by controlling the operation of the first control valve 240 and the heating power of the first heating element 210 and the second heating element 220, and receiving the first temperature information and the second temperature information, so as to meet the user's demand and realize the intelligentization of the pure drinking machine. Preferably, the first temperature detection element 250 and the second temperature detection element 260 are temperature sensing bags.

[0038] Referring to Figure 1 In one embodiment, the water purification machine further comprises a second control valve 420 and a first water pump 410, the water inlet of the first water pump 410 is communicated with the water outlet of the pure water tank 110, the water outlet of the first water pump 410 is communicated with the water inlet of the water outlet module 300, 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 opening and closing 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 communicated with the water outlet of the first water pump 410, and the water outlet of the second control valve 420 is communicated with 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 communicated with 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 purification machine. The second control valve 420 is electrically connected with 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, the water purification machine further comprises a first check valve 430, the first check valve 430 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, and the water inlet of the second control valve 420 is communicated with 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 be opened and the water outlet of the second water pump 160 is communicated with the water inlet of the second control valve 420, the hot water heated by the first heating element 210 can be prevented from flowing back to the water inlet of the second control valve 420, thereby ensuring the water temperature of the water outlet of the second control valve 420 and improving the reliability of the water purification machine.

[0041] Referring to Figure 1 In one embodiment, the water storage module 100 further comprises a raw water tank 120 and a filter element 150, the raw water tank 120 is used to be communicated with an external water source, the water inlet of the filter element 150 is communicated with the water outlet of the raw water tank 120, a second water pump 160 is arranged on the pipeline between the water inlet of the filter element 150 and the water outlet of the raw water tank 120, and the water outlet of the filter element 150 is communicated with the water inlet of the pure water tank 110. The filter element 150 is used to purify the water flowing from the raw water tank 120 into the pure water tank 110.

[0042] Specifically, the second water pump 160 is electrically connected with the controller, and the controller is configured 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 150, thereby effectively improving the drinking water safety of the user and improving the reliability of the water purifier.

[0043] Further, the water storage module 100 further comprises a first water inlet valve 170, which is arranged 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 configured 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 with the controller, and the controller is configured to control the opening and closing of the first water inlet valve 170.

[0044] Referring to Figure 1 In one embodiment, the water storage module 100 further comprises a waste water tank 130, and the water inlet of the waste water tank 130 is communicated with the waste water outlet of the filter 150 to collect the concentrated water generated in the water purification process, so as to realize the recovery of the concentrated water.

[0045] Further, the water storage module 100 further comprises a waste water valve 180, which is arranged on a pipeline between the water inlet of the waste water tank 130 and the waste water outlet of the filter 150, and is configured to control the on-off between the water inlet of the waste water tank 130 and the waste water outlet of the filter 150. The waste water valve 180 is electrically connected with the controller, and the controller is configured to control the opening and closing of the waste water valve 180.

[0046] Referring to Figure 1 In one embodiment, the water storage module 100 further comprises a water storage tank 140 and a partition plate 141, the partition plate 141 is contained in the water storage tank 140 and connected with the tank wall of the water storage tank 140 to divide the water storage tank 140 into a first tank body and a second tank body, the height of the partition plate 141 is lower than the height of the tank wall of the water storage tank 140, so that the upper ends of the first tank body and the second tank body are communicated, and the first tank body is configured as the raw water tank 120 and the second tank body is configured as the waste water tank 130.

[0047] Specifically, the bottom wall of the partition plate 141 is connected with the bottom of the water storage tank 140, and the side wall of the partition plate 141 is connected with the tank wall of the water storage tank 140, so as to divide the water storage tank 140 into a first tank and a second tank which are independent at the lower end and communicated at the upper end. When the raw water tank 120 is filled with external water source, the liquid level of the water source in the raw water tank 120 is higher than the height of the partition plate 141, so that the water source in the waste water tank 130 is also filled, i.e. the waste water tank 130 is communicated 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 source in the raw water tank 120 flows into the filter 150, the concentrated water generated in the water purification process of the filter 150 enters 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 plate 141, the concentrated water is mixed and diluted with the water source in the raw water tank 120, and then enters the filter 150 again, so that the concentrated water is utilized and the water production rate is improved.

[0048] When 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 plate 141, the liquid level of the water source in the waste water tank 130 is leveled with the height of the partition plate 141. When the concentrated water is discharged to the waste water tank 130 in the water purification process of the filter 150, the concentrated water is mixed and diluted with the water source in the waste water tank 130, and then overflows from the partition plate 141 to the raw water tank 120, is mixed and diluted with the water source in the raw water tank 120, and flows into the filter 150 through the water outlet of the raw water tank 120 for utilization. When the volume of the water source in the raw water tank 120 becomes smaller and smaller, and the concentrated water discharged in the water purification process of the filter 150 becomes more and more, so that the content of the concentrated water in the waste water tank 130 becomes higher and higher, the partition plate 141 can retain the water source with high concentration of concentrated water in the waste water tank 130, so that the water source flowing into the raw water tank 120 is the water source mixed and diluted with the concentrated water in the waste water tank 130, thereby avoiding direct filtration and utilization of the concentrated water with high concentration, reducing energy waste, and prolonging the service life of the filter 150.

[0049] Referring to Figure 1 In one embodiment, the water storage module 100 further comprises a water level detection member 190 arranged in the raw water tank 120 and located at the lower end of the raw water tank 120.

[0050] Specifically, the water level detecting member 190 is connected with the tank wall of the raw water tank 120 and electrically connected with the controller, and the installation position of the water level detecting member 190 is lower than the height of the partition plate 141. The water level detecting member 190 is used to detect 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 replace 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, the water source overflowing from the waste water tank 130 through the partition plate 141 is mixed with the water source in the raw water tank 120, and 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 is poor, so that the water needs to be replaced.

[0051] Referring to Figure 1 In one embodiment, the water storage module 100 further comprises a water quality detector arranged 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 with 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 replace the water in the raw water tank 120.

[0056] Specifically, the water liquid in the ice making box 520 which is not condensed into ice can be returned to the cold water tank 510 through the pipeline, so as to prevent the ice from being easily melted due to the presence of water liquid in the ice making box 520, and the water outlet of the water outlet module 300 can discharge ice water, thereby improving the adaptability of the pure drinking machine. Since the water liquid flowing from the ice making box 520 to the cold water tank 510 has a low temperature, the water liquid is used to cool the normal temperature water liquid in the cold water tank 510, thereby improving the cooling capacity utilization rate and reducing the energy consumption of the ice making box 520.

[0057] Further, a drain valve 580 is arranged between the pipeline between the water outlet of the ice making box 520 and the water inlet of the cold water tank 510, and is used to control the on-off between the water outlet of the ice making box 520 and the water inlet of the cold water tank 510. The drain valve 580 is connected with the controller, and the controller is used to control the opening and closing of the drain valve 580.

[0058] Further, the pure drinking machine further comprises a third water inlet valve 450, which is arranged on the pipeline between the water outlet of the fourth water pump 560 and the water inlet of the water outlet module 300, and 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 with the controller, and the controller is used to control the opening and closing of the third water inlet valve 450.

[0060] Specifically, the water outlet of the cold water tank 510 is communicated with the water inlet of the water storage tank 140, and when the water in the cold water tank 510 needs to be emptied for cleaning, the water is discharged into the water storage tank 140 through the pipeline by the fifth water pump 570 for utilization, thereby improving the utilization rate of the water liquid.

[0061] Further, the outlet of the cold water tank 510 is communicated with the inlet of the waste liquid tank, so that the ice water in the cold water tank 510 can be mixed with the water source in the waste water tank 130 to reduce the temperature, and then flow into the raw water tank 120, thereby avoiding that the water flowing into the inlet of the filter 150 through the outlet of the raw water tank 120 has a low temperature, which affects the service life of the filter 150.

[0062] The cold water tank 510 is provided with a high water level detector and a low water level detector, when the water level in the cold water tank 510 is lower than a set value, the third water pump 550 is used to pump water from the pure water tank 110 to the cold water tank 510 to add water, when the water level is higher than the set value, the third water pump 550 stops pumping water.

[0063] Referring to Figure 1 In one embodiment, the purified drinking machine further comprises a second check valve 440, which is arranged on the pipeline between the outlet of the fifth water pump 570 and the inlet of the water storage module 100. The second check valve 440 is arranged on the pipeline between the outlet of the fifth water pump 570 and the inlet of the waste water tank 130, so as to avoid that the water source in the waste water tank 130 flows back to the cold water tank 510 through the pipeline, thereby polluting the water source in the cold water tank 510.
