Description

Technical Field

[0001] This invention relates to the field of household appliance technology, specifically to a water purifier. Background Technology

[0002] With economic development and improved living standards, consumers are paying more and more attention to healthy water and drinking water, and their requirements for water use are also getting higher and higher. As a water treatment device that can deeply filter and purify water according to its usage requirements, water purifiers are gaining increasing recognition and favor from consumers.

[0003] Currently, a multi-functional integrated water purifier and heater has emerged on the market, allowing consumers to simultaneously access both ambient temperature purified water and hot water. This is gradually replacing older water purifiers with only a single purification function. These integrated units include filtration and heating units. However, when the filtration and heating units are integrated into the water purifier, space constraints and installation requirements place high demands on the arrangement of these components within a limited space. This significantly impacts the size, efficiency of disassembly and assembly, lifespan, and reliability of the water purifier. Existing water purifiers of this type vary widely in their arrangement and suffer from numerous defects. Current technologies, due to unreasonable installation structure design, exhibit drawbacks such as difficulty in assembling functional units, complex and non-compact structures, insufficient reliability, and poor assembly stability, causing significant challenges to the manufacturing, installation, and reliable use of water purifiers. Moreover, existing integrated water purifiers and heaters are limited by the filtration efficiency of their filter units, resulting in a fixed output of purified hot water per unit time. This makes it difficult to meet users' large water consumption needs, leading to a poor user experience. Furthermore, existing integrated water purifiers and heaters often suffer from an unreasonable internal layout, resulting in excessively long hot water pipes behind the heating element. When users do not use hot water for a period of time, the remaining hot water in these pipes cools down naturally. When users use hot water again, the residual water in the pipes cannot be reheated. The excessive length of the hot water pipes behind the heating element leads to too much residual water at room temperature, resulting in excessively low water temperatures and negatively impacting the user experience. Summary of the Invention

[0004] This invention provides a water purifier to solve the above-mentioned technical problems.

[0005] The technical solution adopted in this invention is as follows:

[0006] A water purifier, comprising:

[0007] A supporting frame is provided with a first accommodating space and a second accommodating space, the first accommodating space and the second accommodating space being arranged side by side along a first direction;

[0008] A filtration unit is disposed within the first accommodating space along a second direction perpendicular to the first direction; a water purification unit includes a water storage tank connected to the purified water outlet of the filtration unit and a heating component connected to the water outlet of the water storage tank. The water storage tank and the heating component are arranged side by side along the second direction, the heating component is disposed above the water storage tank, and the water outlet of the heating component is located at the top of the water purifier.

[0009] A hot water outlet is provided, which is located near the outlet of the heating element and is directly connected to the outlet of the heating element.

[0010] In hot water mode, the raw water is filtered by the filtration unit and then flows to the storage tank for storage. The purified water in the storage tank is heated by the heating element and then flows directly to the hot water outlet.

[0011] The water purifier of this invention also has the following additional technical features:

[0012] The support frame is provided with a first clearance notch adapted to the water storage tank and a second clearance notch adapted to the heating component. The water storage tank is installed to the support frame from the first clearance notch in a direction opposite to the first direction. The heating component includes a heating element, which is installed to the support frame from the second clearance notch in a direction opposite to the second direction.

[0013] The water storage tank is provided with a stop structure, and the heating element is provided with a limiting structure. The stop structure and the limiting structure stop together to limit the movement of the heating element in the first direction, the opposite direction of the second direction, a third direction perpendicular to the first direction, and / or the direction opposite to the third direction.

[0014] The stop structure includes an outer rib and an inner support rib fixed to the outer rib and extending toward the inner side of the outer rib. The outer rib wraps around at least a portion of the limiting structure to limit the movement of the heating element in the first direction, the third direction and / or the opposite direction of the third direction. The limiting structure abuts against the inner support rib to allow the heating assembly to be supported on the water storage tank.

[0015] The limiting structure has a water inlet pipe that can communicate with the water outlet of the water storage tank, and the stop structure has a notch adapted to the water inlet pipe, with one side of the water inlet pipe extending out along the notch to the outside of the stop structure.

[0016] The heating assembly further includes a positioning bracket for mounting the heating element. The positioning bracket and the heating element are arranged side by side along the first direction. The support frame is provided with a third clearance notch. The positioning bracket is installed to the support frame from the third clearance notch in a direction opposite to the first direction.

[0017] The positioning bracket is provided with a guide groove that matches the heating element. The heating element slides into the positioning bracket from the third clearance notch in a direction opposite to the first direction and is then fixed.

[0018] The filtration unit has a raw water inlet, a purified water outlet, and a wastewater outlet. The purified water outlet can be connected to the first water supply port of the water purifier. The outlet of the heating element can be connected to the second water supply port of the water purifier. The water purifier also includes a water circuit board and a booster pump. The water circuit board has a raw water inlet that can be connected to the raw water inlet, a wastewater outlet that can be connected to the wastewater outlet, a purified water outlet that connects the purified water outlet and the first water supply port, and a hot water outlet that connects the outlet of the heating element and the second water supply port. The booster pump is located on the fluid path between the raw water inlet and the raw water outlet. The support frame has a third accommodating space for accommodating the water circuit board and the booster pump. The first accommodating space, the third accommodating space, and the second accommodating space are arranged side by side along the first direction.

[0019] The support frame is provided with a fourth clearance notch, and the water channel plate is installed to the support frame from the fourth clearance notch in a direction opposite to the second direction; the support frame is provided with a fifth clearance notch, and the booster pump is installed to the support frame from the fifth clearance notch in a third direction perpendicular to the first direction or in a direction opposite to the third direction.

[0020] The booster pump and the water storage tank are arranged side by side along the first direction, the water circuit board and the heating assembly are arranged side by side along the first direction, and the water circuit board and the booster pump are arranged side by side along a direction opposite to the second direction.

[0021] Due to the adoption of the above technical solution, the technical effects achieved by this invention are as follows:

[0022] The water purifier provided by this invention, firstly, improves the compactness of the filter unit and the water purification unit after installation within the support frame by arranging a first accommodating space suitable for installing the filter unit and a second accommodating space suitable for installing the water purification unit side by side along a first direction on the support frame, thus reducing the space occupied in directions other than the first direction. Secondly, this invention adds a water storage tank to the fluid path between the filter unit and the heating component. The water storage tank can temporarily store the purified water flowing out of the filter unit. When a higher temperature and larger flow rate of purified water is required, the water in the storage tank can be delivered to the heating component in real time, improving water treatment efficiency and meeting the user's large water consumption needs. Furthermore, the water storage tank and heating element are arranged side by side along a second direction perpendicular to the first direction, which can make full use of the installation space of the second accommodating space, realize the rational layout of the water circuit and the compact layout of the structure; the heating element is set above the water storage tank, and the outlet of the heating element is close to the hot water outlet at the top of the water purifier. The direct connection between the outlet of the heating element and the hot water outlet greatly simplifies and shortens the pipeline connection from the rear end of the heating element to the hot water outlet of the water purifier and the length of the hot water pipeline, reduces the residual water storage in the pipeline, prevents the residual water in the hot water pipeline from affecting the user's water temperature, and improves the accuracy of the first cup of hot water temperature after a long interval.

[0023] In a preferred embodiment of the present invention, by setting a first clearance notch and a second clearance notch, the water storage tank is installed to the support frame from the first clearance notch in a direction opposite to the first direction, and the heating element is installed to the support frame from the second clearance notch in a direction opposite to the second direction. That is, the water storage tank and the heating element are assembled to the support frame through different clearance notches and different directions during the installation process, and the two do not interfere with each other, thereby helping to simplify their respective structural designs. Moreover, the multi-angle assembly facilitates the assembler's operation process, helps to achieve rapid assembly, and improves assembly efficiency. Furthermore, the installation operation of the water storage tank and the heating element will not interfere with other modules (such as filter units, control units, booster pumps, etc.) installed on the support frame, avoiding the need to remove other parts on the support frame to make way for the installation of the water storage tank and the heating element. The installation is convenient and quick.

[0024] In a preferred embodiment of the present invention, the stop structure of the water storage tank cooperates with the stop structure of the heating element to limit the movement of the heating element in the first direction, the opposite direction of the second direction, a third direction perpendicular to the first direction, and / or the direction opposite to the third direction. This achieves the limitation of the heating element by the water storage tank in one or more directions, ensuring the stability of the heating element installation. At the same time, the limitation of the heating element by the water storage tank can also achieve coarse positioning during the installation process of the heating element, assist in the rapid assembly of the heating element, and facilitate the subsequent fastening of the heating element by the connecting parts.

[0025] In a preferred embodiment, the stop structure includes an outer rib and an inner supporting rib fixed to the outer rib and extending inward toward the inner side of the outer rib. The outer rib and the inner supporting rib form a stop structure with high structural strength, which greatly enhances the load-bearing capacity of the heating element while cooperating with the limiting structure. The limiting structure abuts against the inner supporting rib to ensure that the heating component is supported on the water storage tank, avoiding stress concentration at other fixed positions of the heating component.

[0026] In a preferred embodiment, the limiting structure not only works with the stop structure to limit the heating element, but also includes a water inlet pipe, serving multiple purposes and achieving a compact layout of the heating assembly. The water inlet pipe extends from the notch to the outside of the stop structure for easy pipe connection. Furthermore, in the preferred embodiment where the water tank is detachable, this arrangement of the water inlet pipe guides the loading and unloading of the water tank, facilitating quick assembly and disassembly.

[0027] As a preferred embodiment of the present invention, compared to directly mounting the heating element onto the support frame, the independent positioning bracket is simpler to manufacture, has lower manufacturing costs, and is easier to optimize in terms of its compatibility with the heating element. This reduces the difficulty of installing the heating element and improves its installation stability. During installation, the positioning bracket and the heating element are assembled to the support frame through different clearance notches and in different directions, ensuring they do not interfere with each other. This also allows assembly personnel to observe and clearly define the assembly position and placement of the heating element from multiple angles and directions, ensuring the reliability of the heating element's assembly.

[0028] In a preferred embodiment of the present invention, the water circuit board is provided with a raw water inlet that connects to the raw water inlet, a wastewater outlet that connects to the wastewater outlet, a purified water outlet that connects to the purified water outlet and the first water supply outlet, and a hot water outlet that connects to the heating element and the second water supply outlet. This means the water circuit board integrates all water interfaces, including the raw water inlet, wastewater outlet, purified water outlet, and hot water outlet, resulting in high modularity, simplified overall structure, easier pipe layout, and miniaturization of the entire unit. Furthermore, the support frame is provided with a third accommodating space corresponding to the water circuit board and the booster pump. The first accommodating space, the third accommodating space, and the second accommodating space are arranged side-by-side along the first direction, which helps reduce the thickness of the support frame and further contributes to miniaturization.

[0029] As a preferred embodiment of the present invention, the water circuit board is installed to the support frame from the fourth clearance notch in a direction opposite to the second direction, and the booster pump is installed to the support frame from the fifth clearance notch in a third direction perpendicular to the first direction or in a direction opposite to the third direction. That is, the installation of the water circuit board and the booster pump do not interfere with each other, which facilitates the simultaneous installation of the water circuit board and the booster pump to improve assembly efficiency.

[0030] In a preferred embodiment of the present invention, the booster pump and the water storage tank are arranged side by side along the first direction, the water circuit board and the heating component are arranged side by side along the first direction, and the water circuit board and the booster pump are arranged side by side along the opposite direction to the second direction. This rationalizes the arrangement of each module to shorten the flow path between fluids as much as possible, thereby achieving both structural compactness and facilitating rapid water flow.

[0048] To more clearly illustrate the overall concept of the present invention, a detailed description will be provided below with reference to the accompanying drawings and examples.

[0049] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the scope of protection of the invention is not limited to the specific embodiments disclosed below.

[0050] Furthermore, in the description of this invention, it should be understood that the terms "upper," "lower," "top," "bottom," "inner," "outer," "axial," "radial," "circumferential," "lateral," and "longitudinal," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0051] In this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection, an electrical connection, or a communication connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0052] In this invention, unless otherwise expressly specified and limited, the first feature "on" or "below" the second feature may be in direct contact with the first and second features, or indirect contact through an intermediate medium. In the description of this specification, references to terms such as "one embodiment," "some embodiments," "example," "specific example," or "some examples," etc., indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one embodiment or example of the invention. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0053] Reference Figures 1 to 3 As shown, a water purifier includes a support frame 1, a filter unit, and a water purification unit. The support frame 1 has a first accommodating space 11 for accommodating the filter unit and a second accommodating space 12 for accommodating the water purification unit. The first accommodating space 11 and the second accommodating space 12 are arranged side by side along a first direction. The water purification unit includes a water storage tank 2 that can communicate with the purified water outlet of the filter unit, and a heating component 3 that can communicate with the water outlet of the water storage tank 2. The water storage tank 2 and the heating component 3 are arranged side by side along a second direction perpendicular to the first direction. For ease of understanding, as... Figure 4 As shown, the present invention schematically illustrates the first direction as X, i.e., the water purifier. Figure 4 The state shown is in the direction from left to right; the second direction is set as Y, which is the water purifier. Figure 4 The direction from bottom to top in the state shown; let the third direction, which is perpendicular to both the first and second directions, be Z, i.e. Figure 5 Zhongshui Water Purifier Figure 4 The direction from right to left for the state shown.

[0054] Those skilled in the art will understand that the water purifier provided by the present invention, firstly, by arranging the first accommodating space 11 suitable for installing the filter unit and the second accommodating space 12 suitable for installing the water purification unit side by side on the support frame 1 along the first direction, helps to improve the compactness of the filter unit and the water purification unit after installation in the support frame 1, reduces the space occupied in other directions besides the first direction, and can make the water purifier thinner and lighter.

[0055] Secondly, this invention adds a water storage tank 2 to the fluid path between the filtration unit and the heating component 3. A water pump 4 is installed at the bottom of the water storage tank 2. The water storage tank 2 can temporarily store the purified water flowing out of the filtration unit. When a higher temperature and larger flow rate of purified water is required, the water pump 4 can stably pump the water in the water storage tank 2 to the heating component 3, improving water treatment efficiency and meeting the user's large water consumption needs. Compared with the purified water after filtration by the reverse osmosis filter directly flowing to the heating component 3 for heating, the solution of using the water pump 4 in conjunction with the water storage tank 2 can achieve a stable large flow rate of hot water. The working power of the water pump 4 can be adjusted according to the user's water temperature to achieve the maximum flow rate of water output while meeting the user's water temperature, thus improving the user experience.

[0056] In addition, the water storage tank 2 and the heating component 3 are arranged side by side along a second direction perpendicular to the first direction, which can make full use of the installation space of the second accommodating space 12, realize the rational arrangement of the water circuit and the compact layout of the structure. The heating component 3 is located above the water storage tank 2, and the outlet of the heating component 3 is located at the top of the water purifier.

[0057] As a preferred embodiment of the present invention, such as Figure 1 , Figure 2 and Figure 4 As shown, the support frame 1 is provided with a first clearance notch adapted to the water storage tank 2 and a second clearance notch adapted to the heating component 3. The water storage tank 2 is installed to the support frame 1 from the first clearance notch in a direction opposite to the first direction. The heating component 3 includes a heating element 31, which is installed to the support frame 1 from the second clearance notch in a direction opposite to the second direction.

[0058] Those skilled in the art will understand that, through the setting of the first and second clearance notches, the water storage tank 2 is installed to the support frame 1 from the first clearance notch in a direction opposite to the first direction, and the heating element 31 is installed to the support frame 1 from the second clearance notch in a direction opposite to the second direction. That is, the water storage tank 2 and the heating element 31 are assembled to the support frame 1 through different clearance notches and different directions during the installation process, and the two do not interfere with each other. This helps to simplify their respective structural designs, and the multi-angle assembly facilitates the assembler's operation process, helps to achieve rapid assembly, and improves assembly efficiency. For example, during the installation of the water storage tank 2 in a direction opposite to the first direction, the position of the water storage tank 2 can be observed through the second clearance notch, and during the installation of the heating element 31 in a direction opposite to the second direction, the position of the heating element 31 can be observed through the first clearance notch. Moreover, the installation of the water storage tank 2 and the heating element 31 will not interfere with other modules (such as the filter unit, control unit, booster pump, etc.) installed on the support frame 1, avoiding the need to remove other parts on the support frame 1 to avoid the installation of the water storage tank 2 and the heating element 31, making the installation convenient and quick.

[0059] As a specific embodiment of this implementation, such as Figures 6 to 8 As shown, a stop structure 21 may be provided in the water storage tank 2, and a limiting structure 311 may be provided in the heating body 31. The stop structure 21 and the limiting structure 311 cooperate to limit the movement of the heating body 31 in the first direction, the opposite direction of the second direction, a third direction perpendicular to the first direction, or the direction opposite to the third direction.

[0060] As a preferred embodiment, the stop structure 21 and the limiting structure 311 can cooperate to simultaneously limit the movement of the heating element 31 along the first direction, the opposite direction of the second direction, a third direction perpendicular to the first direction, and the direction opposite to the third direction, which helps to simplify the structure of the heating element 31 and the water storage tank 2.

[0061] Those skilled in the art will understand that the stop structure 21 of the water storage tank 2 cooperates with the limiting structure 311 of the heating element 31 to limit the movement of the heating element 31 in the first direction, the opposite direction of the second direction, a third direction perpendicular to the first direction, and the direction opposite to the third direction. This allows the water storage tank 2 to limit the heating element 31 in one or more directions, ensuring the stability of the heating element 31 during installation and its reliable operation. Simultaneously, the limiting of the heating element 31 by the water storage tank 2 also enables coarse positioning during the installation process, assisting in the rapid assembly of the heating element 31 and facilitating the subsequent tightening of the heating element 31 with screws.

[0062] As a preferred example in this embodiment, such as Figure 6 As shown, the stop structure 21 includes an outer rib 211 and an inner support rib 212 fixed to the outer rib 211 and extending toward the inner side of the outer rib 211. The outer rib 211 wraps around at least a portion of the limiting structure 311 to limit the movement of the heating body 31 in the first direction, the third direction, and the opposite direction of the third direction. The limiting structure 311 abuts against the inner support rib 212 so that the heating assembly 3 is supported on the water storage tank 2.

[0063] Preferably, three inner support ribs 212 arranged in a triangular pattern can be provided inside the outer rib 211, so that the outer rib 211 and the inner support ribs 212 form a stop structure 21 with high structural strength, which greatly reduces the possibility of the stop structure 21 breaking. Moreover, while the stop structure 21 cooperates with the limiting structure 311 to limit the heating element 31, it also greatly improves the load-bearing capacity of the heating element 31. The limiting structure 311 and the inner support ribs 212 abut against each other to make the heating component 3 supported on the water storage tank 2, avoiding stress concentration at other fixed positions of the heating component 3, such as stress concentration at the screw fixing position of the heating element 31.

[0064] As a preferred example in this embodiment, such as Figures 6 to 8 As shown, the limiting structure 311 has an inlet pipe 3111 that can communicate with the outlet of the water storage tank 2, and the stop structure 21 is provided with a notch 213 that is adapted to the inlet pipe 3111. One side of the inlet pipe 3111 extends along the notch 213 to the outside of the stop structure 21.

[0065] Those skilled in the art will understand that by providing a water inlet pipe 3111 that can communicate with the outlet of the water storage tank 2, the limiting structure 311 can not only cooperate with the stop structure 21 to limit the heating element 31, but also communicate with the water storage tank 2, serving multiple purposes. This avoids drilling holes at other locations on the water storage tank 2 to create water inlets, achieving a compact layout of the heating component 3. The water inlet pipe 3111 extends from the notch 213 to the outside of the stop structure 21 for convenient pipe connection. Furthermore, in the preferred embodiment where the water storage tank 2 is detachable, the arrangement of the water inlet pipe 3111 guides the installation and removal of the water storage tank 2, facilitating quick assembly and disassembly. In other words, during the installation of the water storage tank 2 onto the support frame 1 in a direction opposite to the first direction, the orientation and direction of the water inlet pipe 3111 prevent the water storage tank 2 from being installed backwards, thus avoiding rework.

[0066] As a preferred embodiment of the present invention, such as Figure 1 and Figure 4As shown, the heating assembly 3 further includes a positioning bracket 32 ​​for mounting the heating element 31. The positioning bracket 32 ​​and the heating element 31 are arranged side by side along the first direction. The support frame 1 is provided with a third clearance notch. The positioning bracket 32 ​​is installed from the third clearance notch to the support frame 1 in a direction opposite to the first direction.

[0067] Those skilled in the art will understand that, compared to directly mounting the heating element 31 onto the support frame 1, the independent positioning bracket 32 ​​is simpler to manufacture, has lower manufacturing costs, and is easier to optimize in terms of its compatibility with the heating element 31. This reduces the installation difficulty of the heating element 31 and improves its installation stability. During installation, the positioning bracket 32 ​​and the heating element 31 are assembled to the support frame 1 through different clearance notches and in different directions, without interfering with each other. This also allows assembly personnel to observe and clearly define the assembly position and placement of the heating element 31 from multiple angles and directions, ensuring the reliability of the heating element 31's assembly.

[0068] Specifically, such as Figure 7 and Figure 9 As shown, the positioning bracket 32 ​​includes a bracket body 321, a first stop limiting part 322, a second stop limiting part 323, a third stop limiting part 324, a limiting rib 327, and a limiting support rib 328. The first stop limiting part 322 is disposed on the limiting end face of the bracket body 321. The second stop limiting part 323 and the third stop limiting part 324 are both fixedly connected to the bracket body 321 and extend in a direction away from the bracket body 321 along a first direction. The limiting rib 327 and the limiting support rib 328... All are fixedly connected to the bracket body 321 and extend away from the bracket body 321 in a direction opposite to the first direction. The first stop limiting part 322 is used to limit the movement of the heating body 31 in a direction opposite to the first direction. The second stop limiting part 323 is used to limit the movement of the heating body 31 in a direction opposite to the second direction. The third stop limiting part 324 is provided with a screw post 3241, which passes through the heating body 31 and is connected to the screw post 3241 through a screw connector to limit the movement of the heating body 31 in the first direction and in the direction opposite to the first direction. The limiting rib 327 and the limiting support rib 328 are used to limit the movement of the positioning bracket 32 ​​in the direction opposite to the first direction.

[0069] In addition, such as Figures 9 to 11As shown, the supporting frame 1 is provided with a bearing portion 13 for fixing the positioning bracket 32. The positioning bracket 32 ​​has a symmetrical structure, with a first clamping portion 325 and a second clamping portion 326 symmetrically arranged on both sides of the upper part of the positioning bracket 32. A clamping groove for clamping the bearing portion 13 is formed between the first clamping portion 325 and the second clamping portion 326. The first clamping portion 325, the bearing portion 13, and the second clamping portion 326 are arranged sequentially in the opposite direction of the second direction. The bearing portion 13 clamps and fixes itself to the first clamping portion 325 and the second clamping portion 326. Between the two clamping parts 326, the bearing part 13 is clamped in the clamping groove. The bearing part 13 has a U-shaped notch. One end of the limiting rib 327, i.e., the end of the limiting rib 327 facing the bearing part 13, has a limiting groove 3271 with an opening facing the bearing part 13. The limiting groove 3271 fits into the bottom of the U-shaped notch, i.e., the bottom of the U-shaped notch of the bearing part 13 is located in the limiting groove 3271, and the two sides of the U-shaped notch of the bearing part 13 are located in the clamping groove formed by the first clamping part 325 and the second clamping part 326. When assembling the positioning bracket 32, the positioning bracket 32 ​​is first installed to the support frame 1 from the third clearance notch in the direction opposite to the first direction, so that the bearing part 13 is inserted into the limiting groove 3271 and the clamping grooves on the left and right sides of the positioning bracket 32. The positioning bracket 32 ​​relies only on the limiting groove 3271 and the first clamping part 325. The three points of the clamping groove formed between the second clamping part 326 and the support part 13 are positioned within the U-shaped notch, thus achieving the pre-fixation of the positioning bracket 32. Without the need for screw fixing, the limiting slot 3271, in conjunction with the clamping groove, achieves the positioning bracket 32's limitation in the directions opposite to the first direction, the second direction, the direction opposite to the second direction, the third direction, and the direction opposite to the third direction. That is, the positioning bracket 32's longitudinal and lateral limitation can be achieved solely by its own structure. The final fixing of the positioning bracket 32 ​​only requires connecting the support part 13 and the second clamping part 326 with screws to achieve the fixing of the positioning bracket 32. Since the positioning bracket 32's own structure is sufficient to achieve this... The pre-fixing and positioning of the positioning bracket 32 ​​makes installation more convenient, faster, and more stable for installers. The first stop limiting part 322 of the positioning bracket 32 ​​and the third stop limiting parts 324 on the left and right sides form a guide groove 329 that matches the heating body. When installing the heating body 31, it is only necessary to slide the heating body 31 into the guide groove 329 from the second clearance notch in the direction opposite to the second direction. When the heating body 31 abuts against the second stop limiting part 323, it indicates that the heating body 31 has been installed in place. At this time, it is only necessary to fix the heating body 31 to the screw post 3241 with screws. The second stop limiting part 323 plays the role of installation positioning for the heating body.After the heating element 31 is installed onto the positioning bracket 32, since the positioning bracket 32 ​​is only fixedly connected to the upper part of the heating element 31, the center of gravity of the heating element 31 is located below the positioning bracket 32. When the water purifier shakes, the shift in the center of gravity of the heating element 31 will cause the positioning bracket 32 ​​to deflect. Therefore, the positioning bracket 32 ​​is provided with limiting support ribs 328 to support the support frame 1 and prevent the positioning bracket 32 ​​from deflecting in a direction opposite to the first direction.

[0070] As a preferred embodiment of the present invention, although not shown in the accompanying drawings, all the foregoing embodiments and examples of the present invention can further include a raw water inlet, a purified water outlet, and a wastewater outlet. The purified water outlet can be connected to the first water supply port of the water purifier to achieve the output of room temperature purified water from the first water supply port; the outlet of the heating component 3 can be connected to the second water supply port of the water purifier to achieve the output of hot water from the second water supply port.

[0071] In this embodiment, the water purifier further includes a water circuit board and a booster pump. The water circuit board is provided with a raw water inlet that can communicate with the raw water inlet, a wastewater outlet that can communicate with the wastewater outlet, a purified water outlet that connects the purified water outlet and the first water supply outlet, and a hot water outlet that connects the outlet of the heating element 3 and the second water supply outlet. The hot water outlet is close to the outlet of the heating element 3 and is directly connected to the outlet of the heating element 3. The booster pump is located on the fluid path between the raw water inlet and the raw water outlet. Figure 2 As shown, the support frame 1 is provided with a third accommodating space 14 for accommodating the water circuit board and the booster pump. The first accommodating space 11, the third accommodating space 14 and the second accommodating space 12 are arranged side by side along the first direction.

[0072] Those skilled in the art will understand that by providing a raw water inlet that connects to the raw water inlet, a wastewater outlet that connects to the wastewater outlet, a purified water outlet that connects to the purified water outlet and the first water supply outlet, and a hot water outlet that connects to the outlet of the heating component 3 and the second water supply outlet, the water circuit board integrates all water interfaces, including the raw water inlet, wastewater outlet, purified water outlet, and hot water outlet. This high degree of modularity simplifies the overall structure, facilitates pipe layout, and contributes to the miniaturization of the entire unit. Furthermore, the support frame 1 is provided with a third accommodating space 14 corresponding to the water circuit board and the booster pump. The first accommodating space 11, the third accommodating space 14, and the second accommodating space 12 are arranged side-by-side along the first direction, which helps reduce the thickness of the support frame 1, further contributing to miniaturization. Moreover, in the presence of multiple water flow obstructions such as those from the filtration unit and the purified water treatment unit, the booster pump increases water pressure and volume, improves water treatment efficiency, and meets the requirements for large-volume water supply.

[0073] Preferably, such as Figure 3 As shown, a pump body mounting position 15 for installing a booster pump can be set in the third accommodating space 14, and the booster pump and the water circuit board can be arranged side by side along the second direction, that is, the water circuit board is set above the pump body mounting position 15 and the booster pump, making full use of the third accommodating space 14 and rationalizing the layout of the water purifier.

[0074] In a preferred embodiment of this implementation, the support frame 1 may be provided with a fourth clearance notch, and the water circuit board may be installed to the support frame 1 from the fourth clearance notch in a direction opposite to the second direction; the support frame 1 may be provided with a fifth clearance notch, and the booster pump may be installed to the support frame 1 from the fifth clearance notch in a third direction perpendicular to the first direction or in a direction opposite to the third direction.

[0075] Those skilled in the art will understand that by installing the water circuit board to the support frame 1 from the fourth clearance notch in a direction opposite to the second direction, and installing the booster pump to the support frame 1 from the fifth clearance notch in a third direction perpendicular to the first direction or in a direction opposite to the third direction, the installation of the water circuit board and the booster pump do not interfere with each other, which facilitates the simultaneous installation of the water circuit board and the booster pump to improve assembly efficiency. The present invention schematically illustrates that the pump body mounting position 15 faces a direction opposite to the third direction, so the booster pump can be installed to the support frame 1 in the third direction.

[0076] In a preferred embodiment of this implementation, the booster pump and the water storage tank 2 can be arranged side by side along the first direction, the water circuit board and the heating component 3 can be arranged side by side along the first direction, and the water circuit board and the booster pump can be arranged side by side along the opposite direction to the second direction.

[0077] Those skilled in the art will understand that the booster pump and water storage tank 2 are arranged side by side along the first direction, the water circuit board and heating component 3 are arranged side by side along the first direction, and the water circuit board and booster pump are arranged side by side along the opposite direction to the second direction. This rationalizes the arrangement of each module to shorten the flow path between fluids as much as possible, which not only achieves a compact structure but also facilitates the rapid flow of water.

[0078] Regarding the structure of the supporting frame 1, any of the following embodiments can be adopted:

[0079] Example 1: As Figure 3 As shown, the support frame 1 is an integrally formed structure, which improves the integration of the support frame 1 and the installation of various modules such as the filter unit, water purification unit, water circuit board, and booster pump, and simplifies the processing and assembly process.

[0080] Example 2: Although not shown in the accompanying drawings, the supporting frame 1 may also include a first bracket with the first accommodating space 11 and a second bracket with the second accommodating space 12. The first bracket and the second bracket are separately formed structures, and the first bracket and the second bracket are fixedly connected and cooperate to form the third accommodating space 14.

[0081] Those skilled in the art will understand that, in embodiments where the support frame 1 is a split-form structure including a first bracket and a second bracket, multiple different types of water purifiers can share the first bracket and the filter unit. For different types of water purifiers, only the second bracket and the corresponding heating component need to be redesigned. Alternatively, multiple different types of water purifiers can share the second bracket and the heating component. For different types of water purifiers, only the first bracket and the corresponding filter unit need to be redesigned, thus shortening the development cycle and reducing mold investment costs.

[0082] For any parts not mentioned in this invention, existing technologies can be used or referenced.

[0083] The various embodiments in this specification are described in a progressive manner. The same or similar parts between the various embodiments can be referred to each other. Each embodiment focuses on describing the differences from other embodiments.

[0084] The above description is merely an embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of the present invention should be included within the scope of the claims of the present invention.
