[0028] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0029] In daily life, water purifiers are installed under kitchens and in water dispensers. Long-term use will cause debris to mix into the filter element of the water purifier, affecting the service life of the filter element and thus the water purification effect of the water purifier. Once the filter element reaches the end of its service life, the cost of replacing the element will increase. In addition, water purifiers are often installed inside, making repair and maintenance inconvenient.

[0030] In order to effectively protect the filter element of the water purifier and extend the service life of the filter element, an embodiment of the present application provides an integrated water use device, which sets a reflux branch to return water to the water purification module, flushes and soaks the filter element of the water purification module, desorbs and regenerates the filter element, extends the service life of the filter element, and reduces the cost of replacing the filter element.

[0031] For details, please refer to Figure 1 and Figure 2 The integrated water equipment provided in the embodiment of the present application includes a shell, and a water inlet 1 and a first water outlet 17 are arranged on the surface of the shell; a first branch 100 is arranged in the shell, and the first branch 100 is arranged between the water inlet 1 and the first water outlet 17 to obtain the first type of water. In the embodiment of the present application, the first type of water is domestic water, and the integrated water equipment is installed in the kitchen; a gas heating module 8 is arranged on the first branch 100, and the gas heating module 8 is arranged near the first water outlet 17 to heat the first type of water; in order to ensure the health and hygiene of kitchen water, the integrated water equipment provided in the embodiment of the present application is installed with a water purification module 4, that is, a water purifier, and the first type of water generated by the first branch 100 is filtered through at least a part of the water purification module 4 to purify the first type of water; it is emphasized that the embodiment of the present application is provided with a second branch 200 in the shell, and the second branch 200 is arranged between the gas heating module 8 and the water purification module 4. The second branch 200 serves as a regeneration branch of the water purification module 4, so that the heated first type of water flows back to the water purification module 4 to rinse the filter element of the water purification module 4. Through such an arrangement, the filter element of the water purification module 4 is flushed and soaked, so that the filter element is desorbed and regenerated, thereby extending the service life of the filter element and reducing the cost of replacing the filter element.

[0032] In an optional example, the second branch 200 includes a first regeneration branch 210, the water purification module 4 includes a first filter element 42, and the first regeneration branch 210 is arranged through the first filter element 42 to soak the first filter element 42. Further, the second branch 200 includes a second regeneration branch 220, the water purification module 4 also includes a second filter element 44, and the second regeneration branch 220 is arranged through the second filter element 44 to soak the second filter element 44. Further, the second branch 200 also includes a third regeneration branch 230, and the third regeneration branch 230 is used to rinse the first filter element 42 and the second filter element 44.

[0033] Specifically, Figure 4 As shown, a cleaning control diagram of the filter element by the integrated water-using equipment provided in an embodiment of the present application is shown, such as Figure 2As shown, a first control valve 19, a second control valve 20, a third control valve 21, a fourth control valve 22, a fifth control valve 23, a sixth control valve 24, a seventh control valve 25, an eighth control valve 26 and a ninth control valve 27 are arranged between the first branch 100 and the second branch 200. When the first filter element 42 is cleaned, the cleaning mode includes three sub-modes, namely, emptying, soaking and rinsing. Firstly, to start the emptying mode, it is only necessary to open the third control valve 21 to discharge the water retained in the first filter element 42 from the first water outlet 17, and at this time, the other control valves are all in the closed state. Secondly, when the soaking mode is executed after the emptying is completed, only the third control valve 21 is opened to discharge the water retained in the first filter element 42 from the first water outlet 17, and at this time, the other control valves are all in the closed state. It is necessary to open the first control valve 19 and the seventh control valve 25, and the other control valves are in the closed state. Then, the heated first type of water will flow back to the first filter element 42 and stay in the first filter element 42 to soak the filter element and remove stubborn debris, bacteria and other microorganisms on the first filter element 42. Furthermore, the user can choose to empty the first filter element 42 again, and the operation is the same as above. Finally, start the flushing mode, open the third control valve 21 and the ninth control valve 27 at the same time, and the other control valves are in the closed state, so that water flows through the first filter element 42 and then flows out, completing a flushing and soaking process of the first filter element 42, so that the filter element can be desorbed and regenerated.

[0034] Similarly, when cleaning the second filter element 44, the cleaning mode also includes three sub-modes, namely emptying, soaking and flushing; first, to start the emptying mode, it is only necessary to open the fifth control valve 23 to discharge the water retained in the second filter element 44 from the first water outlet 17, and the other control valves are in a closed state at this time; secondly, when executing the soaking mode after the emptying is completed, it is only necessary to open the first control valve 19 and the eighth control valve 26, and the other control valves are in a closed state, then the heated first type of water will flow back to the second filter element 44 and stay in the second filter element 44, soaking the filter element, and removing the stubborn debris and bacteria and other microorganisms on the second filter element 44; furthermore, the user can choose to empty the second filter element 44 again, and the operation is the same as above; finally, start the flushing mode, open the sixth control valve 24 and the ninth control valve 27 at the same time, and the other control valves are in a closed state, so that the water flows through the second filter element 44 and then flows out, completing a flushing and soaking process of the second filter element 44, so that the filter element can be desorbed and regenerated.

[0035] In an optional example, the first filter element 42 and the second filter element 44 are activated carbon / carbon rods. It should be noted that the embodiment of the present application uses the first type of water, i.e., domestic water, to rinse the filter element. Ordinary domestic water has no effect on the desorption and regeneration of the filter element. Therefore, in order to have a good desorption and regeneration effect, the embodiment of the present application selects the first filter element 42 and the second filter element 44 as activated carbon and carbon rods that are easy to clean as an optimal technical solution; and the embodiment of the present application uses high-temperature hot water to reflux to the activated carbon / carbon rod filter element to desorb and regenerate it, so that it regains the adsorption and purification capabilities.

[0036] Furthermore, the water purification module 4 of the embodiment of the present application is also provided with a PP cotton filter element 41 and a reverse osmosis membrane filter element (RO membrane filter element 43). The above-mentioned activated carbon / carbon rod filter element is mainly used to remove residual chlorine, discolored and odorous substances, and improve the taste. The PP cotton filter element 41 is mainly used to remove large particle impurities such as mud, rust, etc. The RO membrane filter element 43 can intercept bacteria and reduce harmful substances such as organic matter and heavy metals in water.

[0037] In an additional example of the present application, the first category of water, namely domestic water, includes tap water. During use in the kitchen, unfiltered tap water is usually used for flushing basins, water tanks, etc., and will be directly treated as waste water after use without purification. Therefore, the first branch 100 includes a first bypass branch 110 that does not pass through the water purification module 4, and the first bypass branch 110 is provided with a first control valve 19 for opening the first bypass branch 110 to obtain the above-mentioned tap water.

[0038] Furthermore, the first category of water, namely domestic water, also includes purified water. In daily life water use, purified water is usually used for washing vegetables, etc. In order to ensure the cleanliness of the surface of vegetables, etc., impurities in the water need to be removed. Therefore, the first branch 100 includes a second bypass branch 120 passing through the PP cotton filter element 41 and the first filter element 42. The PP cotton filter element 41 is used to remove mud, rust, suspended matter, residual chlorine and other substances. The second bypass branch 120 is provided with a second control valve 20 and a third control valve 21 for opening the second bypass branch 120 to obtain purified water.

[0039] It should be noted that the second bypass branch 120 includes two routes, namely, passing through the first filter element 42 and not passing through the first filter element 42 .

[0040] Furthermore, the first type of water, namely domestic water, includes domestic pure water, which is drinkable. The first branch 100 includes a fourth bypass branch 140 passing through a PP cotton filter element 41, a first filter element 42, an RO membrane filter element 43 and a second filter element. The fourth bypass branch 140 is provided with a fifth control valve 23 for opening the fourth bypass branch 140 to obtain domestic pure water.

[0041] It should be noted that, in the embodiment of the present application, in order to ensure smooth water inflow and enable water to smoothly enter the water purification module 4, the integrated water use device is provided with a first water pump 16 between the first bypass branch 110, the second bypass branch 120 and the third bypass branch 130, and the flow force of the water flow is increased by the first water pump 16; on the first branch 100 provided in the embodiment of the present application, the branch passing through the water purification module 4, namely the second bypass branch 120, the third bypass branch 130 and the fourth bypass branch 140, as shown Figure 2As shown, it is not difficult to see that the water flow passing through the fourth bypass branch 140 must pass through the second bypass branch 120 and a part of the third bypass branch 130. Therefore, in order to ensure that the water flow can completely pass through all water purification processes of the water purification module 4, it is a preferred solution to set the first water pump 16 to provide power on the branch passing through the water purification module 4 in the embodiment of the present application. Preferably, in order to make the purification branch controllable, a sixth control valve 24 can also be set on the path where the first water pump 16 is set, and part of the water purification path is controlled by the sixth control valve 24; for example, Figure 2 As shown, the sixth control valve 24 controls whether to activate the third bypass branch 130 and the fourth bypass branch 140. In general, the sixth control valve 24 is in a normally open state.

[0042] In an additional example of the present application, the first branch 100 provided in the embodiment of the present application is provided with a first water inlet temperature probe 5 and a first water outlet temperature probe 15. The first water inlet temperature probe 5 is arranged near the water inlet 1, and the first water outlet temperature probe 15 is arranged near the first water outlet 17. In actual applications, the first type of water, namely domestic water, needs to be temperature-controlled in order to obtain water with a suitable temperature. In order to accurately control the water temperature, it is necessary to accurately obtain the water inlet temperature and the water outlet temperature. Therefore, in the embodiment of the present application, the first water inlet temperature probe 5 and the first water outlet temperature probe 15 are respectively arranged at the water inlet 1 and the first water outlet 17 of the first branch 100. Further, the first branch 100 is provided with a first water flow sensor 3. The first water flow sensor 3 is used to measure the water outlet flow of the first type of water. The water temperature is measured by the two probes, and the first water flow is measured by the inlet flow through the sensor 3. Then, through the gas heating module 8 on the first branch 100, it is selected whether to perform temperature heating treatment on the water. In this way, water with a suitable temperature can be obtained according to user needs.

[0043] In an optional example, the integrated water use equipment provided in the embodiment of the present application is provided with a second water outlet 12 on the housing, and the integrated water use equipment further comprises a third branch 300 provided between the water inlet 1 and the second water outlet 12, and the third branch 300 is provided through the water purification module 4 to obtain the second type of water after purification by the water purification module 4. The third branch 300 is provided with an electric heating module 10 to heat the second type of water, and the third branch 300 is provided with a high-pressure switch 28, and the high-pressure switch 28 is used to control the water purification module 4 to be turned on and off to prepare the second type of water.

[0044] It should be noted that the second type of water is drinking water, and the third branch 300 is a branch for producing drinking water. In order to ensure the healthy water quality of drinking water and meet the user's demand for healthy water, all drinking water produced by the third branch 300 must pass through all filter elements of the water purification module 4 for water purification filtration to ensure that the drinking water is absolutely healthy and safe. In addition, an electric heating module 10 is arranged on the third branch 300 to heat the drinking water and provide hot drinking water to the user.

[0045] In an additional example of the present application, the embodiment of the present application sets a second water pump 7 on the third branch 300, i.e., the drinking water branch, so as to ensure that the third branch 300 can obtain drinking water smoothly.

[0046] Preferably, in order to ensure that there is always drinking water in the third branch 300 and that it can be used by users at any time, a high-pressure switch 28 is provided on the third branch 300 in the embodiment of the present application. The function of the high-pressure switch 28 is to control the start and stop of the water purification module 4. In this way, it can be ensured that users can access drinking water at any time.

[0047] In another additional example of the present application, the third branch 300 is provided with a second water inlet temperature probe 9 and a second water outlet temperature probe 11. The second water inlet temperature probe 9 is arranged near the water inlet 1, and the second water outlet temperature probe 11 is arranged near the second water outlet 12. In actual applications, the second type of water, namely drinking water, needs to be temperature-controlled in order to obtain water with a suitable temperature. In order to accurately control the water temperature, it is necessary to accurately obtain the water inlet temperature and the water outlet temperature. Therefore, in the embodiment of the present application, the second water inlet temperature probe 9 and the second water outlet temperature probe 11 are respectively arranged at the water inlet 1 and the second water outlet 12 of the third branch 300. The water temperature is measured by the two probes, and then the electric heating module 10 on the third branch 300 is used to select whether to heat the water. In this way, water with a suitable temperature can be obtained according to user needs.

[0048] Furthermore, the third branch 300 is provided with a second water flow sensor 6, and the second water flow sensor 6 is used to measure the outflow flow of the second type of water.

[0049] Furthermore, the integrated water-use equipment provided in the embodiment of the present application is provided with an air inlet 2 on the surface of the shell. During the water temperature detection and water flow detection process, the air inlet 2 is opened to control the working condition of the gas heating module 8 by coordinating the air volume in the third branch 300. The water flow sensor and the water inlet temperature probe on the water inlet pipe detect the water inlet flow and water inlet temperature, and the water outlet temperature probe on the water outlet pipe detects the water outlet temperature, thereby accurately adjusting the water outlet temperature.

[0050] In an additional example of the present application, the integrated water use device provided in the embodiment of the present application also includes a storage tray 13 arranged on the surface of the shell, and the storage tray 13 can be used to place kitchen utensils, etc., so that the user can use the integrated water use device to collect water.

[0051] In an optional example, the shell is provided with a wastewater outlet 18, and the integrated water use equipment further includes a fourth branch 400 provided between the water purification module 4 and the wastewater outlet 18 to discharge the wastewater.

[0052] According to the integrated water use equipment provided in the embodiment of the present application, a second branch is set in the equipment to allow the heated first-class water to flow back to the water purification module, so as to rinse and soak the filter element of the water purification module, desorb and regenerate the filter element, extend the service life of the filter element, and reduce the cost of replacing the filter element; in addition, the integrated water use equipment provided in the embodiment of the present application also integrates gas water use equipment, drinking water equipment and water purification equipment into one, which is convenient for users to use and improves the user's water use experience.
