DETAILED DESCRIPTION

[0041] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0042] The terms "first," "second," and so on, in the specification and claims of this utility model and the accompanying drawings are used to distinguish different objects, not to describe a specific order. Furthermore, the terms "including," "having," and any variations thereof are intended to cover non-exclusive inclusions. For example, a process, method, system, product, or apparatus comprising a series of steps or elements is not limited to the listed steps or elements but may optionally include steps or elements not listed, or may optionally include other steps or elements inherent to the process, method, product, or apparatus.

[0043] References herein to "embodiments" or "implementations" mean that a particular feature, structure, or characteristic described in connection with the embodiments or implementations may be included in at least one embodiment of the present invention. The appearance of such phrases in various places in the specification does not necessarily refer to the same embodiment, nor do they constitute independent or alternative embodiments that are mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0044] Water purifiers in the related art can purify and heat water. When a user requires hot water, the purified water is heated by a heater to the desired temperature. However, when a high-flow water flow is required, the heater is affected by the heating power and water output, resulting in a long heating time and low water output efficiency.

[0045] Moreover, in the related art, the heater and the filter element are arranged in the same accommodating cavity. The heater generates a large amount of heat when working. The high temperature may cause the activity of the active substance in the filter element to change, affecting the normal use of the filter element.

[0046] To facilitate subsequent explanation, Figure 1 The perspectives shown define a first direction and a second direction, wherein the first direction is parallel to the X-axis, i.e. Figure 1 As shown in the direction from left to right, the second direction is parallel to the Y axis, that is, Figure 1 The following description of the first direction and the second direction is referred to here.

[0047] In view of this, this embodiment provides a water purifier 100. The water purifier 100 can achieve high-flow water output.

[0048] See also Figure 1 and Figure 2 As shown, the present invention provides a water purifier 100, comprising:

[0049] The housing 10 includes: an installation cavity 11, a first accommodating cavity 12, and a second accommodating cavity 13. The installation cavity 11, the first accommodating cavity 12, and the second accommodating cavity 13 are sequentially arranged along a first direction;

[0050] The filter element 30 is disposed in the installation cavity 11. The filter element 30 has a filter element water inlet 31, a first filter element water outlet 32, and a second filter element water outlet 33. The first filter element water outlet 32 ​​is used to supply water to the water-using equipment.

[0051] The heat storage tank 40 is arranged in the second accommodating chamber 13. The heat storage tank 40 has a heat storage tank water inlet 41 and a heat storage tank water outlet 42. The heat storage tank water inlet 41 is connected to the second filter element water outlet 33, and the heat storage tank water outlet 42 is connected to the water-using equipment.

[0052] The shell 10 in the present invention is used to install the booster pump 20, the filter element 30, and the heat storage tank 40. Specifically, the installation cavity 11 is used to install and fix the filter element 30, the first accommodating cavity 12 is used to install and fix the booster pump 20, and the second accommodating cavity 13 is used to install and fix the heat storage tank 40. Water flows into the water purifier 100 from the booster pump water inlet 21, and flows out through the booster pump water outlet 22 after being pressurized by the booster pump 20, and then flows into the filter element 30 through the filter element water inlet 31 for filtration. The filtered water can be directly supplied to the water-using equipment through the first filter element water outlet 32 ​​or flow out through the second filter element water outlet 33. The water flowing out of the second filter element water outlet 33 enters the heat storage tank 40 through the heat storage tank water inlet 41. The heat storage tank 40 heats the filtered water entering the heat storage tank 40 and heats it to a preset stability. When the user needs a large flow of water, the filtered water can be supplied to the user through the heat storage tank water outlet 42. In this solution, filtered water at room temperature, heated water, and mixed hot and cold water can be provided to users.

[0053] It can be understood that the above-mentioned shell 10 is divided into an installation chamber 11 (for installing the filter element 30), a first accommodating chamber 12 (for installing the booster pump 20), and a second accommodating chamber 13 (for installing the heat storage tank 40). The installation chamber 11, the first accommodating chamber 12, and the second accommodating chamber 13 are arranged in sequence along the first direction. This is to separate the heat tank and the filter element 30. This is because the heat storage tank 40 generates a large amount of heat when heating the filtered water, and the properties of the active substance in the filter element 30 will change at high temperature, which will affect the service life of the filter element 30. After separating the heat storage tank 40 and the filter element 30, the impact of the temperature generated by the heat storage tank 40 on the filter element 30 can be greatly reduced, thereby ensuring the service life and normal use of the filter element 30.

[0054] As can be understood, the filter element 30 is provided with a filter element water inlet 31 and two water outlets. After entering the filter element 30 and being purified, the unpurified water flows out through two outlets, namely a first filter element water outlet 32 ​​and a second filter element water outlet 33. The first filter element water outlet 32 ​​is used to directly provide filtered water to the user, and the second filter element water outlet 33 is connected to the heat storage tank 40 to provide filtered water to the heat storage tank 40. In this way, filtered water at room temperature or hot water heated by the heat storage tank 40 can be directly provided to the user.

[0055] It can be understood that the heat storage tank 40 is used to store the water filtered by the filter element 30, and to heat and keep it warm. When the water flows into the heat storage tank 40, the heat storage tank 40 starts to heat the water flow and heats it to a preset temperature (the preset temperature can be 40°~90°). When the user needs to use hot water, it can be transported to the water-using equipment through the water outlet 42 of the heat storage tank.

[0056] In some embodiments, the boost pump 20;

[0057] The booster pump 20 is arranged in the first accommodating chamber 12, and the booster pump 20 has a booster pump water inlet 21 and a booster pump water outlet 22. The booster pump water inlet 21 is connected to the water supply pipeline; the booster pump water outlet 22 is connected to the filter element water inlet 31.

[0058] It can be understood that the booster pump 20 provided in the first accommodating chamber 12 is used to pressurize the raw water. This is because the filter element 30 is provided with an RO (Reverse Osmosis) membrane. Generally, the water pressure of the water flow itself may not be sufficient to allow the water flow to pass through the RO. In order to allow the water flow to pass through the filter element 30 smoothly, a booster pump 20 is provided to ensure that the water flow can flow into the filter element 30 while ensuring the purification efficiency of the filter element 30.

[0059] See also Figure 2 In some embodiments, the housing 10 includes a first side plate 14, a second side plate 15, a bottom plate 16, and a partition plate 17;

[0060] The first side plate 14 and the second side plate 15 are spaced apart and arranged on the bottom plate 16 along the second direction, and the partition plate 17 is arranged on a side of the first side plate 14 and the second side plate 15 close to the heat storage tank 40;

[0061] The first side panel 14 and the second side panel 15 are both perpendicular to the bottom panel 16 , and the partition 17 is perpendicular to the first side panel 14 and / or the second side panel 15 and / or the bottom panel 16 ;

[0062] The first side plate 14 , the second side plate 15 , the bottom plate 16 , and the partition plate 17 together form the installation cavity 11 .

[0063] It can be understood that the first side plate 14 and the second side plate 15 are two side plates of the housing 10 along its length direction. The first side plate 14 and the second side plate 15 are respectively arranged on the two sides of the bottom plate 16, and the first side plate 14 and the second side plate 15 are arranged perpendicular to the bottom plate 16. The partition plate 17 is arranged in the middle or at one end of the first side plate 14 and the second side plate 15. The partition plate 17, the first side plate 14, the second side plate 15 and the bottom plate 16 together enclose the installation cavity 11. The partition plate 17 is configured to be an arc shape that adapts to the filter element 30.

[0064] The installation cavity 11 is semi-enclosed, with both the top and the side away from the heat storage tank 40 being open, making it easy to install or remove the filter element 30. The installation cavity 11 is located on the side away from the heat storage tank 40, and its semi-enclosed design also isolates the heat generated by the heat storage tank 40, preventing the heat from affecting the filter element 30 and deteriorating the filter material in the filter element 30, thereby affecting the normal use of the filter element 30.

[0065] See also Figures 2 to 4 , in some embodiments, further comprising a plurality of limiting members 50;

[0066] The installation cavity 11 has a limiting portion 111, and the limiting portion 111 is located in the installation cavity 11. Multiple limiting members 50 are arranged on the first side plate 14 and the second side plate 15. The limiting members 50 are arranged to be separated from the limiting portion 111. A slide groove 61 is formed between the limiting portion 111 and the limiting member 50. The slide groove 61 cooperates with the filter element 30 to fix the filter element 30.

[0067] It can be understood that the installation cavity 11 includes a limiting portion 111, and the limiting portion 111 is located in the installation cavity 11, and its position is as follows: Figure 2 The upper part shown, as Figure 2 The lower portion shown is a limiting portion 111, which is primarily used to limit movement of the filter element 30 along a first direction. The limiting portion 111 is recessed relative to the mounting cavity 11, i.e., the inner diameter of the mounting cavity 11 is smaller than the inner diameter of the limiting portion 111. Limiting members 50 are disposed on opposite sides of the limiting portion 111, and the limiting members 50 are spaced apart from the limiting portion 111. This forms a chute 61 between the limiting members 50 and the limiting portion 111. The chute 61 can cooperate with the guide member 60 provided on the filter element 30 to confine the filter element 30 within the mounting cavity 11, preventing the filter element 30 from moving longitudinally. Due to gravity, the filter element 30 also does not move in the vertical direction of the filter element 30. This improves the stability of the filter element 30 after installation, ensuring that the filter element 30 does not move during normal use, thereby improving the stability of the water purifier 100.

[0068] See also Figure 3 and Figure 4 and Figure 7 , in some embodiments, further comprising a guide member 60;

[0069] The filter element 30 has a handle 36, and the guide member 60 is arranged on the outer periphery of the handle 36. The guide member 60 is adapted to the slide groove 61. The handle 36 can be rotated along the filter element 30. When the handle 36 is rotated along the filter element 30 to be parallel to the first direction, the guide member 60 is parallel to the slide groove 61, and the guide member 60 can be inserted into the slide groove 61.

[0070] As can be understood, a handle 36 is provided at the top of the filter element 30, and the handle 36 can be rotated along the top of the filter element 30. Two guide members 60 are provided, and the guide members 60 are arranged at intervals on the handle 36 and are arranged at a portion close to the filter element 30. The two filter elements 30 are arranged relatively on the handle 36. When the handle 36 is rotated along the filter element 30, the guide member 60 also rotates with the handle 36. When the handle 36 is rotated to be parallel to the first direction, that is, when the handle 36 is parallel to the top of the filter element 30, the guide member 60 can be inserted into the slide groove 61. At this time, the slide groove 61 and the guide member 60 cooperate to complete the fixation of the filter element 30, so that the filter element 30 cannot move in the longitudinal direction, and due to gravity, it will not move in the vertical direction of the filter element 30. This can improve the stability of the filter element 30 after installation, ensure that the filter element 30 will not move during normal use, and thereby improve the stability of the water purifier 100.

[0071] See also Figure 9 In some embodiments, the filter element 30 includes a PPC composite filter element 34 and an RO filter element 35, and the water flow is filtered through the booster pump 20, the PPC composite filter element 34, and the RO filter element 35 in sequence.

[0072] It can be understood that the filter element 30 includes a PPC composite filter element 34 and an RO filter element 35. When filtering water, the water flow first passes through the composite filter element 30 for coarse filtration, and then passes through the RO filter element 35 for fine filtration, and then flows out of the filter element 30 through the water outlet of the filter element 30; since the filtration accuracy of the RO filter element 35 is high, it is difficult to make the source water pass through the reverse osmosis membrane by relying on the water pressure of ordinary tap water. Therefore, the water flow is first pressurized by the booster pump 20 before flowing into the filter element 30, so that the water flow can flow smoothly through the RO filter element 35 to filter the water flow, which can also increase the purification speed of the filter element 30 and improve the working efficiency of the water purifier 100.

[0073] The PPC composite filter element 34 is a filter element 30 that combines PP cotton and activated carbon. The RO filter element 35 is a reverse osmosis water purifier filter element 30 and is a common filter element 30 of the water purifier 100.

[0074] See also Figure 8 In some embodiments, a circuit board 81 is further included; the shell 10 also has a third accommodating chamber 18, and the third accommodating chamber 18 is arranged away from the first accommodating chamber 12 and / or the second accommodating chamber 13. The circuit board 81 is arranged in the third accommodating chamber 18, and the circuit board 81 is respectively connected to the booster pump 20 and the heat storage tank 40.

[0075] It can be understood that a third accommodating chamber 18 is further provided in the shell 10, and the third accommodating chamber 18 is provided on a side of the shell 10 away from the first accommodating chamber 12 or the second accommodating chamber 13 (that is, the third accommodating chamber 18 is spaced apart from the first accommodating chamber 12). The third accommodating chamber 18 is used to accommodate a circuit board 81. The circuit board 81 is fixedly provided in the third accommodating chamber 18, and the circuit board 81 is respectively connected to the booster pump 20 and the heat storage tank 40 for controlling the operation of the booster pump 20 and the heat storage tank 40. Specifically, a temperature sensor can be provided in the heat storage tank 40. When the temperature sensor detects that the temperature of the heat storage tank 40 is lower than the preset temperature, the circuit board 81 controls the operation of the heat storage tank 40 to heat the water flow in the heat storage tank 40.

[0076] Alternatively, a water level detector is provided in the heat storage tank 40. When the water level detector detects that the water level in the heat storage tank 40 is low, the booster pump 20 is controlled to work, purify the water flow and store it in the heat storage tank 40. When the water level in the heat storage tank 40 reaches a preset water level, the circuit board 81 can control the booster pump 20 to stop working.

[0077] See also Figure 9 In some embodiments, the water purifier 100 further includes a vane pump 82; the vane pump 82 is disposed in the second accommodating chamber 13, and the vane pump 82 is respectively connected to the water outlet 42 of the heat storage tank and the water-using equipment. The vane pump 82 is used to supply the hot water in the heat storage tank 40 to the water-using equipment.

[0078] It can be understood that the vane pump 82 is arranged in the second accommodating chamber 13, that is, the vane pump 82 and the heat storage tank 40 are both arranged in the second accommodating chamber 13, and the vane pump 82 is respectively connected to the water outlet of the heat storage tank 40 and the water-using equipment to deliver the hot water in the heat storage tank 40 to the user end. Specifically, the hot water in the heat storage tank 40 flows out through the water outlet 42 of the heat storage tank and flows to the vane pump 82. The vane pump 82 pressurizes the hot water and delivers it to the user end for user use. The vane pump 82 can ensure that the setting position of the heat storage tank 40 is not affected by the water pressure, and can smoothly deliver the hot water in the heat storage tank 40 to the water-using equipment to improve the user experience.

[0079] See also Figure 9 In some embodiments, the water purifier 100 further includes: a one-way valve 83 ; an exhaust port 43 is provided on the top of the heat storage tank 40 , and the exhaust port 43 is provided with a one-way valve 83 .

[0080] As will be appreciated, the top of the heat storage tank 40 is provided with an exhaust port 43. When the heat storage tank 40 heats the water flow therein, water vapor is generated in the heat storage tank 40, which increases the pressure within the heat storage tank 40. The exhaust port 43 is provided at the top of the heat storage tank 40 to allow the water vapor to be smoothly discharged to the outside of the heat storage tank 40 without affecting the storage of hot water in the heat storage tank 40. A one-way valve 83 is provided at the exhaust port 43. The one-way valve 83 can be a safety valve or a one-way safety valve. When the pressure within the heat storage tank 40 exceeds a preset value, the valve core of the one-way valve 83 is lifted by the air pressure, i.e., the one-way valve 83 is opened, thereby enabling the water vapor within the heat storage tank 40 to be discharged.

[0081] See also Figure 5 and Figure 6 , in some embodiments, further comprising a mounting base 70;

[0082] A groove 71 is provided on the mounting base 70 , and a guide block 72 is provided on a side of the filter element 30 away from the handle 36 . When the filter element 30 is mounted on the mounting base 70 , the guide block 72 is located in the groove 71 .

[0083] It can be understood that the mounting base 70 is used to install the filter element 30. A water channel structure compatible with the filter element 30 is provided on the mounting base 70, and a groove 71 is provided on the mounting base 70. The groove 71 runs through the top of the mounting base 70, and a guide block 72 is provided on the side of the filter element 30 away from the handle 36. The guide block 72 is used to cooperate with the groove 71. When the filter element 30 is installed to the base, the guide block 72 is inserted into the groove 71 to achieve positioning of the filter element 30. At the same time, the filter element 30 cooperates with the guide block 72 to limit the rotation of the filter element 30 along its circumferential direction. This can improve the stability of the filter element 30 after installation, ensure that the filter element 30 will not move during normal use, and thereby improve the stability of the water purifier 100.

[0084] See also Figure 2 , in some embodiments, further comprising a plurality of fixing members 80;

[0085] A plurality of fixing members 80 are arranged on the side wall of the second accommodating cavity 13 along the second direction. The heat storage tank 40 is installed on the fixing members 80 . The fixing members 80 are used to fix the heat storage tank 40 .

[0086] As can be understood, the fixing member 80 is used to fix the heat storage tank 40. Multiple fixing members 80 are arranged on the side wall of the second accommodating chamber 13 along the second direction. Multiple fixing members 80 are arranged at intervals. The fixing members 80 can also play a role in positioning the heat storage tank 40. The fixing member 80 is configured to have a shape that adapts to the heat storage tank 40. For example, when the heat storage tank 40 is configured to be curved, the fixing member 80 is also configured to be curved. When the heat storage tank 40 is configured to be square, the fixing member 80 is configured to be plate-shaped and connected to one side of the fixing member 80 to fix the heat storage tank 40. At the same time, the fixing member 80 can also isolate part of the temperature of the heat storage tank 40, allowing a small amount of the temperature of the heat storage tank 40 to be transferred to the housing 10, thereby extending the service life of the housing 10.

[0087] In some embodiments, a heat insulation sheet is further provided in the second accommodating chamber 13. The heat insulation sheet can keep the heat storage tank 40 warm and isolate the heat from the first accommodating chamber 12. This not only improves the heat preservation performance of the heat storage tank 40, but also reduces the impact of the heat of the heat storage tank 40 on other components in the water purifier 100, causing damage to other components.
