[0040] In this document, the term "embodiment" or "implementation" means that the specific features, structures, or characteristics described in connection with the embodiment or implementation can be included in at least one embodiment of the present application. The appearance of this phrase in various places in the specification does not necessarily mean the same embodiment, nor is it an independent or alternative embodiment to other embodiments. Those skilled in the art explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments.

[0041] The water purifier in the related art can purify water quality and heat the purified water. When the user needs hot water, the heater heats the purified water stored in the heating tank to achieve hot water at the required temperature. When cleaning the water purifier, the residual liquid in the heating tank needs to be drained, but the heating tank in the related art cannot drain the residual liquid in the heating tank.

[0042] In view of this, the present embodiment provides a water purifier 100 . The water purifier 100 can completely drain the residual liquid in the heating tank 10 .

[0043] See also Figure 1 and Figure 2 , a water purifier 100, comprising:

[0044] A heating tank 10 having a water outlet 11 disposed at the bottom of the heating tank 10;

[0045] The drainage component 20 has a water inlet 21, a first drain outlet 22, and a second drain outlet 23. The water inlet 21 is connected to the water outlet 11. The first drain outlet 22 is used to supply water to the water-using equipment. The second drain outlet 23 is used to discharge the water in the heating tank 10. The first drain outlet 22 is perpendicular to the second drain outlet 23.

[0046] The above-mentioned water purifier 100 is provided with a water outlet 11 at the bottom of the heating tank 10, and a drainage component 20 is provided on the water outlet 11. The first drain outlet 22 provided on the drainage component 20 can transport the hot water in the heating tank 10 to the water-using equipment, and the second drain outlet 23 provided on the drainage component 20 can discharge the hot water in the heating tank 10 to the outside of the heating tank 10, and the position of the first drain outlet 22 is perpendicular to the second drain outlet 23, so that the water flow from the first drain outlet 22 can completely flow into the second drain outlet 23, so that the water flow in the drainage component 20 and the heating tank 10 is completely discharged, and the water flow in the second drain outlet 23 is also completely discharged, which is convenient for cleaning or maintenance of the heating tank 10.

[0047] It can be understood that the heating tank 10 is arranged in the water purifier 100, and a water outlet 11 is provided at the bottom of the heating tank 10, which is used to discharge the water in the heating tank 10. A water inlet 21 is also provided at the top of the heating tank 10, which is used to add pure water into the heating tank 10, and the heated water is discharged through the water outlet 11.

[0048] It can be understood that the drainage component 20 is provided with a water inlet 21 and a first drain outlet 22 and a second drain outlet 23, wherein the water inlet 21 is connected to the water outlet 11, and the hot water in the heating tank 10 is supplied to the first drain outlet 22 and the second drain outlet 23. The axis of the first drain outlet 22 is arranged perpendicular to the axis of the second drain outlet 23, so that the water that is not discharged in the first drain outlet 22 can flow back to the second drain outlet 23, and then be discharged through the second drain outlet 23, so as to avoid the liquid in the drainage component 20 and the heating tank 10 from being completely discharged, and to avoid residual liquid in the drainage component 20, so that the residual liquid flows back into the heating tank 10 or the liquid in the heating tank 10 is not completely discharged, thereby improving the discharge efficiency of the water flow, so as to facilitate the cleaning or maintenance of the heating tank 10.

[0049] See also Figure 2 In some embodiments, the drainage assembly 20 further includes a first solenoid valve 24 and a second solenoid valve 25;

[0050] The first solenoid valve 24 is disposed at the first drain port 22 , and the second solenoid valve 25 is disposed at the second drain port 23 . The first solenoid valve 24 is connected to a first drain pipe 27 , and the second solenoid valve 25 is connected to a second drain pipe 28 .

[0051] It can be understood that the drainage assembly 20 also includes a first solenoid valve 24 and a second solenoid valve 25, wherein the first solenoid valve 24 is arranged at the first drain port 22, and a first drain pipe 27 is arranged on the first solenoid valve 24, and the first solenoid valve 24 is used to control the opening or closing of the first drain port 22 to allow the water in the heating tank 10 to flow to the water-using equipment, or to close the water flow to the water-using equipment; the second solenoid valve 25 is arranged on the second drain port 23, and a second drain pipe 28 is arranged on the second solenoid valve 25, and the second solenoid valve 25 is used to control the opening and closing of the second drain port 23 to discharge the water in the heating tank 10.

[0052] When the first solenoid valve 24 is open and the second solenoid valve 25 is closed, water can be discharged through the first drain port 22 into the first drain pipe 27 and then output to the water-using equipment through the first drain pipe 27;

[0053] When the first solenoid valve 24 is closed and the second solenoid valve 25 is opened, the water can be discharged through the second drain port 23 to discharge the water in the heating tank 10 .

[0054] When the first solenoid valve 24 and the second solenoid valve 25 are both opened, water flows out through the second drain port 23 , and the water remaining in the first drain pipe 27 also flows back into the drain assembly 20 and then flows out through the second drain port 23 .

[0055] See also Figure 3In some embodiments, the drainage assembly 20 further comprises a vane pump 26.

[0056] The vane pump 26 is arranged at the bottom of the heating tank 10, and the vane pump 26 is connected with the water outlet 11 and the connecting pipe respectively. The vane pump 26 is used to deliver the hot water in the heating tank 10 to the connecting pipe.

[0057] It can be understood that one end of the vane pump 26 is connected with the water outlet 11 of the heating tank 10, and the other end is connected with the drainage assembly 20. In actual use scenarios, the water purifier 100 is mostly placed in a cabinet and at a lower position. The vane pump 26 is mainly arranged to pressurize the water flow in the heating tank 10, so that the water flow in the heating tank 10 can be delivered to the water using equipment. Specifically, the hot water in the heating tank 10 flows out through the water outlet 11 of the heating tank 10 and flows into the vane pump 26. After the water flow is pressurized by the vane pump 26, it is delivered to the user end for use by the user. The vane pump 26 can ensure that the setting position of the heating tank 10 is not affected by water pressure, and can smoothly deliver the hot water in the heating tank 10 to the water using equipment, thereby improving the user experience.

[0058] Please refer to Figure 3 In some embodiments, the water purifier 100 further comprises a liquid level sensor 30.

[0059] The liquid level sensor 30 is arranged in the heating tank 10, and the liquid level sensor 30 is used to detect the liquid level in the heating tank 10.

[0060] It can be understood that the liquid level sensor 30 is arranged inside the heating tank 10. The liquid level sensor 30 is mainly used to detect the height of the current liquid level in the heating tank 10. After the liquid level sensor 30 detects the current liquid level height of the heating tank 10, it can send relevant control instructions according to the liquid level height. When the liquid level height reaches the preset height, the control water replenishing pump stops working. When the liquid level height is low, the control water replenishing pump replenishes the liquid in the heating tank 10.

[0061] Please refer to Figure 4 and Figure 5 In some embodiments, the water purifier 100 further comprises a housing 40.

[0062] The housing 40 comprises a mounting cavity 41, a first accommodating cavity 42, and a second accommodating cavity 43. The mounting cavity 41, the first accommodating cavity 42, and the second accommodating cavity 43 are arranged in sequence along a first direction.

[0063] It can be understood that the above-mentioned shell 40 is divided into a mounting cavity 41 (for mounting the filter element 60), a first accommodating cavity 42 (for mounting the booster pump), and a second accommodating cavity 43 (for mounting the heating tank 10). The mounting cavity 41, the first accommodating cavity 42, and the second accommodating cavity 43 are sequentially arranged along the first direction. This is to separate the heating tank and the filter element 60. Because the heating tank 10 generates a large amount of heat when heating the filtered water, and the active substance in the filter element 60 changes in nature in a high-temperature environment, which affects the service life of the filter element 60. Separating the heating tank 10 and the filter element 60 can greatly reduce the influence of the high temperature generated by the heating tank 10 on the filter element 60, so as to ensure the service life and normal use of the filter element 60.

[0064] Please refer to Figure 4 and Figure 5 In some embodiments, the water purifier 100 further comprises a booster pump 50 and a filter element 60.

[0065] The filter element 60 is arranged in the mounting cavity 41, the booster pump 50 is arranged in the first accommodating cavity 42, and the heating tank 10 is arranged in the second accommodating cavity 43. The booster pump is connected with the filter element 60, and the filter element 60 is connected with the heating tank 10. The heating tank 10 is used for supplying water to a water-using device.

[0066] It can be understood that the filter element 60 is arranged in the mounting cavity 41, the booster pump 50 is arranged in the first accommodating cavity 42, and the heating tank 10 is arranged in the second accommodating cavity 43. The booster pump arranged in the first accommodating cavity 42 is used for pressurizing the water flow entering the water purifier 100. Because the filter element 60 has an RO (Reverse Osmosis) membrane, it is difficult for ordinary tap water pressure to make the source water pass through the RO membrane. Therefore, the water flow is pressurized by the booster pump before flowing into the filter element 60, so that the water flow can smoothly flow through the RO filter element 60 to filter the water flow and improve the purification speed of the filter element 60, thereby ensuring the purification efficiency of the filter element 60.

[0067] It can be understood that the filter element 60 comprises a PPC composite filter element 60 and an RO filter element 60. When filtering water, the water flow first passes through the composite filter element 60 for rough filtration, then passes through the RO filter element 60 for fine filtration, and then flows out of the filter element 60 through the water outlet 11 and flows into the heating tank 10. The above-mentioned PPC composite filter element 60 is a filter element 60 that combines the use of PP cotton and activated carbon. The RO filter element 60 is a reverse osmosis pure water machine filter element 60.

[0068] Please refer to Figure 4 and Figure 5 In some embodiments, the shell 40 comprises a first side plate 44, a second side plate 45, a bottom plate 46, and a partition plate 47.

[0069] The first side plate 44 and the second side plate 45 are spaced apart from each other on the bottom plate 46 along the second direction, and the partition plate 47 is provided on a side of the first side plate 44 and the second side plate 45 close to the heating tank 10;

[0070] The first side plate 44 and the second side plate 45 are both perpendicular to the bottom plate 46 , and the partition plate 47 is perpendicular to the first side plate 44 and / or the second side plate 45 and / or the bottom plate 46 ;

[0071] The first side plate 44 , the second side plate 45 , the bottom plate 46 , and the partition plate 47 together form the installation cavity 41 .

[0072] It can be understood that the first side plate 44 and the second side plate 45 are two side plates of the shell 40 along its length direction, and the first side plate 44 and the second side plate 45 are spaced apart on the two sides of the bottom plate 46, and the first side plate 44 and the second side plate 45 are both arranged perpendicular to the bottom plate 46, and the partition plate 47 is vertically arranged between the first side plate 44 and the second side plate 45, so that the partition plate 47 and the first side plate 44, the second side plate 45 and the bottom plate 46 together enclose the installation cavity 41; wherein, the partition plate 47 is set to an arc shape that is adapted to the filter element 60.

[0073] As can be understood, the installation cavity 41 is semi-enclosed, with the top and the side away from the heating tank 10 both open, which facilitates the installation or removal of the filter element 60. The installation cavity 41 is located on the side away from the heating tank 10, which can also isolate the heat generated by the heating tank 10, preventing the heat generated by the heating tank 10 from affecting the filter element 60, causing the filter material in the filter element 60 to deteriorate and affecting the normal use of the filter element 60.

[0074] See also Figure 4 and Figure 6 , in some embodiments, the water purifier 100 further includes a plurality of limiting members 70;

[0075] The plurality of limiting members 70 are arranged on the first side plate 44 and the second side plate 45 . The mounting cavity 41 has a limiting portion 71 . A slide groove 72 is formed between the limiting portion 71 and the limiting member 70 . The slide groove 72 cooperates with the filter element 60 to fix the filter element 60 .

[0076] As will be understood, the mounting cavity 41 includes a limiting portion 71, which is located within the mounting cavity 41 and is primarily used to limit movement of the filter element 60 along a first direction. The limiting portion 71 is recessed relative to the mounting cavity 41, i.e., the inner diameter of the mounting cavity 41 is smaller than the inner diameter of the limiting portion 71. The limiting members 70 are disposed on opposite sides of the limiting portion 71, and the limiting members 70 are spaced apart from the limiting portion 71, such that a chute 72 is formed between the limiting members 70 and the limiting portion 71. The chute 72 can cooperate with a guide member 80 provided on the filter element 60 to confine the filter element 60 within the mounting cavity 41, preventing the filter element 60 from moving longitudinally. Due to gravity, the filter element 60 also does not move in the vertical direction of the filter element 60. This improves the stability of the filter element 60 after installation, ensuring that the filter element 60 does not move during normal use, thereby improving the stability of the water purifier 100.

[0077] See also Figure 4 、 Figure 6 and Figure 7 , in some embodiments, the water purifier 100 further includes a guide member 80;

[0078] The filter element 60 has a handle 61, which can be rotated along the filter element 60. The guide member 80 is arranged on the outer periphery of the handle 61. The guide member 80 is adapted to the slide groove 72. The guide member 80 can be inserted into the slide groove 72 to limit the movement of the guide member 80 along the first direction.

[0079] As can be understood, a handle 61 is provided at the top of the filter element 60, and the handle 61 can be rotated along the top of the filter element 60. Two guide members 80 are provided, and the guide members 80 are arranged at intervals on the handle 61 and are arranged at a part close to the filter element 60. The two filter elements 60 are arranged relatively on the handle 61. When the handle 61 is rotated along the filter element 60, the guide member 80 also rotates with the handle 61. When the handle 61 is rotated to be parallel to the first direction, that is, when the handle 61 is parallel to the top of the filter element 60, the guide member 80 can be inserted into the slide groove 72. At this time, the slide groove 72 cooperates with the guide member 80 to complete the fixation of the filter element 60, so that the filter element 60 cannot move in the longitudinal direction, and due to gravity, it will not move in the vertical direction of the filter element 60. This can improve the stability of the filter element 60 after installation, ensure that the filter element 60 will not move during normal use, and thereby improve the stability of the water purifier 100.

[0080] See also Figure 8 , in some embodiments, the water purifier 100 further includes: a one-way valve 91;

[0081] An exhaust port 90 is provided on the top of the heating tank 10 , and a one-way valve 91 is provided on the exhaust port 90 .

[0082] It can be understood that the top of the heating tank 10 is provided with an exhaust port 90, when the heating tank 10 heats the water flow in the heating tank 10, water vapor will be generated in the heating tank 10, which will make the pressure in the heating tank 10 become larger, and the exhaust port 90 is used to exhaust the water vapor in the heating tank 10. The exhaust port 90 is arranged at the top of the heating tank 10, so that the water vapor can be smoothly discharged to the outside of the heating tank 10, and does not affect the storage of hot water in the heating tank 10, and the exhaust port 90 is provided with a one-way valve 91, which can be a safety valve or a one-way safety valve, when the pressure in the heating tank 10 is greater than the preset value, the valve core of the one-way valve 91 is lifted by the air pressure, that is, the one-way valve 91 is opened, so that the water vapor in the heating tank 10 can be discharged.
