Description

Technical Field

[0001] This utility model relates to the field of water purifier technology, and more specifically, to a water circuit component for a water purifier. Background Technology

[0002] As people's demands for drinking water quality increase, water purifiers, with their combined functions of water purification and instant heating, have become essential equipment in homes and offices. Existing water purifiers typically employ an integrated water circuit design, where water filtration, distribution, and heating control are achieved on a single circuit board. While this simplifies water pipe connections, it also results in a complex and bulky circuit board structure, occupying significant internal space. This restricts the machine's layout, hindering the rational arrangement of other key components and making it difficult to balance space efficiency with efficient functional module collaboration. Consequently, it impacts the overall compactness and assembly efficiency of the machine.

[0003] A search revealed several patents, such as CN116172405A, which discloses a water circuit component and a water purifier. This design employs a dual water circuit board, integrating multiple channels on the first board for connection to solenoid valves and heat exchange structures, and multiple channels on the second board for connection to the water pump. This avoids complex water pipe connections and helps reduce the overall size of the machine. Another patent, CN216737780U, discloses a horizontally mounted water purifier where the water circuit component is divided into a first, second, and third water circuit board. The water circuit component is installed in the mounting space above the water pump, shortening the distance between the pump and the component, and consequently shortening the length of the water pipe connecting the pump and the component. This results in a more compact internal structure and reduced space occupation. It is evident that the industry has already recognized the importance of using multiple water circuit boards to reduce space consumption, but further optimization and improvement are still possible in practice, especially given the varying design requirements for different models.

[0022] The present invention will be further described below with reference to the embodiments.

[0023] Example Combination Figures 1-9 As shown, this embodiment provides a water circuit component for a water purifier, including: The support frame has filter cartridges 110 and pump mounting brackets 120 distributed vertically along the height of the machine body. Filter cartridges and booster pumps 122 are installed inside the frame, respectively, with horizontally arranged filter elements and booster pumps 122 installed inside. The purification water circuit board 130 is longitudinally located at the rear end of the support frame along its length and is fitted with the filter element and connected to the booster pump 122. In practice, the purification water circuit board 130 may be equipped with a pure water outlet 131. Water circuit board 220 is distributed perpendicularly to the purified water circuit board 130, located on the outside of the filter cartridge frame 110 and extending longitudinally. The inlet end of water circuit board 220 is connected to the pure water outlet of purified water circuit board 130. Water circuit board 220 is used to distribute purified pure water. In practice, the outlet end of water circuit board 220 is connected to drinking water outlet 212.

[0024] This embodiment employs a dual-waterway design. The purification waterway plate 130 is fitted with the filter element and integrates the valve group, pump group components, etc., required for purification treatment (details omitted), including connection to the booster pump 122, which pumps the pre-filtered water into the RO membrane filter element. The top of the purification waterway plate 130 may have a water outlet area, including a pure water outlet 131, a raw water inlet, and a wastewater outlet, where the pure water outlet 131 can be used as a pipeline machine interface, etc. The purification waterway plate 130, together with the installed filter element and the booster pump 122, forms a basic universal module for filtration and purification. The second waterway plate 220 is located on a different plane from the purification waterway plate 130. The second waterway plate 220 is used for subsequent treatment of the purified pure water, such as heating, and finally discharged through the drinking water outlet 212. The two sets of water circuit boards work together to effectively reduce the overall volume. The components required for raw water purification and pure water treatment are integrated into different water circuit boards. Each water circuit board has fewer components, which is more conducive to reducing the volume. In addition, the two are distributed on different planes, which can make full use of the side space of the filter cartridge 110 and promote a compact layout inside the machine.

[0025] In this embodiment, taking the subsequent heating treatment of pure water as an example, it also includes a heating element 210. The heating element 210 and the water circuit board 220 are arranged on the same radial side of the filter cartridge frame 110, saving space in the width direction of the machine body. The water circuit board 220 is connected to the inlet end of the heating element 210 and is used to deliver pure water to the heating. The drinking water outlet 212 includes a hot water outlet.

[0026] Furthermore, the support frame is provided with filter cartridge frames 110 at the top and bottom along the height direction. The top filter cartridge frame 110 houses a first filter element 111, which combines pre- and post-filter elements, while the bottom filter cartridge frame 110 houses an RO membrane filter element. A pump mounting bracket 120 is located between the two filter cartridge frames 110, forming a booster pump mounting area 121. The booster pump 122 is horizontally mounted within the booster pump mounting area 121. The water circuit board 220 is detachably mounted on the upper and lower filter cartridge frames 110. More specifically, the pump mounting bracket 120 has a placement opening for placing the booster pump 122 on the side facing the water circuit board 220, and the filter cartridge frame 110 extends radially beyond this placement opening; along the length of the machine body, the water circuit board 220 at least covers a portion of the placement opening. In practice, the radial width of the filter cartridge holder 110 generally exceeds the width of the booster pump 122. By aligning the water circuit board 220 with at least a portion of the booster pump installation area 121, the area beyond the radial extension of the filter cartridge holder 110 can be fully utilized, avoiding wasted space.

[0027] The specific configuration of the support frame is further described below. An electrical control frame 202 is located at the top of the support frame. The electrical control module (not shown in the attached diagram) is installed on the electrical control frame 202, specifically within the electrical control installation area enclosed by the electrical control frame 202. An inner installation area is formed below the electrical control frame 202 on the support frame. A water outlet 212 is located at the rear end of the support frame. Along the front-to-back length of the machine body, a heating element 210, a water circuit board 220, and a heat preservation box 230 are sequentially arranged from back to front in the inner installation area. The inlet end of the heating element 210 is connected to the outlet end of the heat preservation box 230, and the outlet end of the heating element 210 is connected to both the inlet end of the heat preservation box 230 and the water outlet 212 of the machine body.

[0028] In this embodiment of the water purifier, the heat preservation box 230 is used to keep the hot water heated by the heating element 210 warm and store it, so as to realize the preheating of hot water. According to the actual use needs, the preheated hot water in the heat preservation box 230 can be sent back to the heating element 210 for reheating, so as to realize the rapid and large flow of hot water and ensure the accuracy of hot water temperature.

[0029] In this embodiment, the heating element 210 and the heat preservation box 230 are respectively the main high-temperature components inside the machine body. The heating element 210 and the heat preservation box 230 are separated and located at the front and rear ends of the machine body, respectively. A water circuit board 220 is set between the two. The water circuit board 220 is equipped with water circuit components such as valve groups, pump groups, and pipelines. As a low-temperature component inside the machine body, the water circuit board 220 is set between the high-temperature components at both ends, forming an alternating layout of main high-temperature zone, low-temperature zone, and secondary high-temperature zone inside the machine body. This greatly avoids heat concentration in the high-temperature zone, helps to achieve rapid heat dissipation of the high-temperature components at both ends, avoids the adverse effects of heat concentration on other components, and improves the reliability and operational stability of the machine body.

[0030] Secondly, in this embodiment, the drinking water outlet 212 is specifically a hot water outlet, located at the rear end of the machine body. The heating element 210 is located at the rear end of the machine body, corresponding to the position of the drinking water outlet 212. This not only effectively saves pipe length and promotes a compact and simple layout inside the machine body, but also helps to reduce temperature loss, ensure the accuracy of hot water temperature, and improve the user experience.

[0031] In addition, this embodiment installs the electronic control module at the top of the machine body, which helps to achieve water and electricity separation, avoids the risk of water ingress into the electronic control module, and uses the electronic control frame 202 to separate it from the inner mounting area below, so that the electronic control module is distributed relatively independently and separated from the high-temperature components in the mounting area below, further reducing heat transfer to the electronic control module and ensuring service life and stability.

[0032] Furthermore, the electronic control frame 202 extends along the length of the machine body, and at least a portion of the electronic control frame 202 covers the extended length of the lower water channel plate 220, preferably mainly covering the low-temperature zone where the lower water channel plate 220 is located, further reducing heat transfer from the high-temperature zone to the electronic control module. Specifically, in conjunction with... Figure 1 As shown, the length of the electrical control frame 202 mainly covers the area above the water circuit board 220, with its tail end located in front of the heating element 210 and offset from the main high-temperature zone. The front part covers the area above the insulation box 230. An upper window 201 is formed at the front of the electrical control frame 202, which facilitates the inspection and maintenance of the insulation box 230 below.

[0033] This embodiment also includes an adapter 240. More preferably, the front end of the support frame has a front plate 204, and the adapter 240 is mounted on the front side of the front plate 204 facing away from the inner mounting area. The adapter 240 also serves as a secondary high-temperature component. The front plate 204 separates the insulation box 230 from the adapter 240, reducing heat transfer and heat concentration between the two. Furthermore, placing the adapter 240 at the very front of the machine body facilitates direct heat dissipation to the outside of the machine body. Additionally, placing both the adapter 240 and the electronic control module on the outside of the inner mounting area facilitates the separation and routing of electrical wires within the machine body. In particular, high-voltage lines can be routed from the outside of the support frame, while low-voltage lines are concentrated on the inside of the inner mounting area, ensuring separation of high and low voltage circuits and further improving the reliability and stability of the system operation.

[0034] In practice, the heating element 210 can be specifically designed as follows: a rear plate 205 is provided at the rear end of the support frame, and a heating element mounting area 211 is formed on the front side of the rear plate 205. More specifically, a mounting plate 213 can be provided in front of the rear plate 205. The mounting plate 213 and the rear plate 205 together form the heating element mounting area 211, and the heating element 210 is located in the heating element mounting area 211. The drinking water outlet 212 is located at the top of the rear end of the support frame and is connected to the outlet end of the heating element 210. The mounting plate 213 can be provided at the upper and lower ends of the heating element 210 to form an effective positioning support for the heating element 210 and to form a relatively independent heating element mounting area 211, separating the heating element 210 from other surrounding components and effectively reducing the heat diffusion of the main high-temperature area inward.

[0035] As a preferred design scheme for the supporting frame, combined with Figures 4-5 As shown, the support frame includes a purification frame 100 and a functional frame 200 arranged side-by-side along the left-right width direction of the machine body. The purification module is installed on the purification frame 100, and the heating element 210, water circuit board 220, and insulation box 230 are all distributed in the inner mounting area of ​​the functional frame 200. More preferably, the purification frame 100 and the functional frame 200 are designed to be detachable, such as by using four-corner bolts for fixing. The purification frame 100 only integrates basic purification functions, and the installed purification module can serve as a general-purpose purification module. The functional frame 200 can integrate heating, insulation, or other functional modules according to user needs. Users can combine the general-purpose purification module with different functional modules as needed, achieving the versatility of the purification module and helping to reduce costs.

[0036] Specifically, combined Figure 3 As shown, the right side of the booster pump mounting area 121, away from the functional frame 200, is the mounting and fixing side, and the booster pump 122 is fixed on this side plate. Furthermore, there is a gap between the rear end of the pump mounting bracket 120 and the purified water circuit board 130, allowing the necessary valve groups, pump components, etc., to be installed on the front side plate of the purified water circuit board 130.

[0037] Furthermore, combining Figures 4 to 6As shown, the pump mounting bracket 120 has an open area on the side facing the functional frame 200, providing a placement opening for the booster pump 122. A mounting panel 206 is provided on the side of the functional frame 200 facing the purification frame 100. The mounting panel 206 is connected to the purification frame 100 and covers at least a portion of the placement opening. The mounting panel 206 and the pump mounting bracket 120 together form the mounting chamber for the booster pump 122. The mounting panel 206 and the pump mounting bracket 120 are located on different sides of the frame, and the detachable design of the purification frame 100 and the functional frame 200 helps reduce vibration transmission and vibration noise from the booster pump 122. In practice, it is further preferred that the front-to-back extension length of the booster pump mounting area 121 is greater than the length of the booster pump 122 itself, allowing for the use of a higher-power booster pump 122 as needed.

[0038] In this embodiment, the drinking water outlet 212 is preferably located at the top rear end of the functional frame 200. The top rear end of the functional frame 200 may also be provided with a room temperature water outlet, etc., which, together with the interface area at the top rear end of the purification frame 100, form a concentrated interface area at the top rear end of the body, which facilitates the centralized distribution of pipelines.

[0039] In practice, the outlet end of the heating element 210 needs to be connected to both the insulation box 230 and the drinking water outlet 212. This can be achieved using a reversing valve 203, combined with... Figure 1 and Figure 2 As shown, more specifically, a reversing valve 203 is also provided above the heating element 210 within the functional framework 200. The outlet end of the heating element 210 is connected to the inlet of the reversing valve 203. The first outlet of the reversing valve 203 is connected to the water inlet end of the insulation box 230, and the second outlet of the reversing valve 203 is connected to the drinking water outlet 212 above. By placing the reversing valve 203 above the heating element 210, directly on the communication path between the heating element 210 and the drinking water outlet 212, the shortest pipeline design between the outlet end of the heating element 210 and the drinking water outlet 212 is achieved. The heated hot water can reach the drinking water outlet 212 directly through the shortest path, effectively reducing heat loss and ensuring the accuracy of the hot water outlet temperature. Specifically, the reversing valve 203 is located above the mounting plate 213, which separates it from the heating element 210.

[0040] In this embodiment, the machine body has two sets of water circuit boards, including a purification water circuit board 130 and a second water circuit board 220. The purification water circuit board 130 mainly integrates the valve group, pump group and other components required for the purification function. The side of the purification water circuit board 130 facing the filter cartridge frame 110 is the mounting surface, and the components are concentrated on one side to reduce the space occupied in the length direction. There is a component mounting area between the tail end of the pump mounting bracket 120 and the mounting surface of the purification water circuit board 130 to make full use of the spare space in the length direction between the filter cartridge frame 110 and the pump mounting bracket 120.

[0041] The second water circuit board 220 is mainly distributed inside the functional frame 200, located between the heating element 210 and the insulation box 230. Along the length of the machine body, the second water circuit board 220 extends to at least cover part of the component mounting area of ​​the purified water circuit board 130, making the distribution of water circuit components relatively concentrated and making full use of space. The second water circuit board 220 mainly integrates various valve groups, pump groups, sensor detection, and other components required for the purified water system. For example, it includes a diaphragm pump to directly deliver purified water to the heating element 210, and an outlet valve for controlling the water output, etc., which will not be elaborated further. Furthermore, the sides of the second water circuit board 220 facing and away from the filter cartridge holder 110 are both component mounting surfaces, allowing water circuit components to be installed from both sides, making full use of the gap space.

[0042] Water circuit board 220 and purification water circuit board 130 are arranged independently, which not only saves more space and facilitates a compact layout, but also allows purification water circuit board 130 to serve as a general purification water circuit board, together forming a general purification module. As needed, only the functional components on water circuit board 220 need to be adjusted to achieve the application of different models.

[0043] To further optimize the internal layout and improve space compactness, combined with Figure 8 and Figure 9 As shown, the functional frame 200 has a mounting panel 206 on the side facing the purification frame 100. The mounting panel 206 has an opening area 207 extending through the entire thickness. The water channel plate 220 is at least partially embedded within the opening area 207. More precisely, the surface of the water channel plate 220 can be completely embedded within the opening area 207 and fixedly connected to the purification frame 100, specifically by bolts to the filter cartridge frame 110. The left side of the water channel plate 220 is a component mounting surface, where the main components are distributed within the inner mounting area of ​​the functional frame 200. Similarly, the right side of the water channel plate 220 can also serve as a component mounting surface, where some components are mounted.

[0044] In this embodiment, the opening area 207 is located on the rear side closer to the heating element 210 in the length direction of the machine body. Since the booster pump 122 is shorter than the filter element and is preferably located closer to the front side of the machine body, there is still a certain gap space between the rear end of the booster pump 122 and the purified water circuit plate 130. This embodiment utilizes the opening area 207 to make full use of the side space between the upper and lower filter cartridge frames 110, especially the side space in the rear area, so that the water circuit plate 220 can be embedded from the opening area 207. Components can be installed on both the left and right sides of the water circuit plate 220. The main components are concentrated in the installation area within the functional frame 200 on the right side, reducing the occupancy of the water circuit plate 220 in the width direction of the machine body. This can correspondingly reduce the left and right width of the functional frame 200, making the machine body narrower and the model more compact. Furthermore, the right side of the water circuit board 220 is fixed on the filter cartridge frame 110, which will not put pressure on the thin plate-shaped mounting panel 206, and also improves the installation stability of the water circuit board 220.

[0045] Secondly, in conjunction with the detachable design of the functional frame 200 and the purification frame 100, this embodiment fixes the water circuit board 220 to the purification frame 100. When water circuit maintenance is required, simply remove the fixing bolts at the four corners of the functional frame 200 and remove a few obstructing pipes on the water circuit board 220, and the entire functional frame 200 connected to the components installed on top can be directly removed. Figure 7 As shown in the diagram, this allows for thorough inspection of the water circuit board 220. Compared to fixing the water circuit board 220 to the functional frame 200, this effectively reduces the complexity of disassembly and makes actual operation easier.

[0046] In addition, combined Figure 9 As shown, in practice, it is further preferred that the upper part of the mounting panel 206 is provided with an upper arc-shaped surface 206a and the lower part with an lower arc-shaped surface 206b, so as to fit and conform to the outer wall surfaces of the two sets of filter cartridge frames 110 distributed vertically, ensuring the tight fit between the functional frame 200 and the purification frame 100. The mounting panel 206 is also provided with a second opening area 208 and a third opening area 209 that extend through the thickness. The second opening area 208 is located in the front part of the lower arc-shaped surface 206b, that is, between the insulation box 230 and the lower filter cartridge frame 110, which can effectively avoid the filter cartridge frame 110 and make the distribution of the insulation box 230 more compact in the limited space. The opening area 3 209 is located in the front part of the middle of the mounting panel 206, which is adapted to the front end position of the booster pump 122. Part of the booster pump 122 can be exposed through the opening area 3 209, which is convenient for inspection and maintenance of the booster pump 122. It can also avoid the front end area of ​​the booster pump 122, saving space and avoiding contact between the insulation box 230 and the booster pump 122, thus reducing vibration transmission.

[0047] The scope of protection of this utility model is defined only by the claims. Thanks to the teachings of this utility model, those skilled in the art will readily recognize that alternative structures to the disclosed structure can be used as feasible alternative implementations, and that the disclosed implementations can be combined to produce new implementations, which also fall within the scope of the appended claims.
