Description

Technical Field

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

[0002] As people's demands for drinking water quality increase, water purifiers, which integrate filtration, heating, and other functions, are gradually becoming the mainstream drinking water equipment in homes and offices. The interior of a water purifier typically contains complex functional components such as filter cartridges, water pumps, heating modules, control circuit boards, and water circuit systems. These components need to be rationally arranged within a limited space to meet the market demand for miniaturization and compactness of the entire machine, while ensuring the efficient operation of each functional module.

[0003] However, the high degree of integration within the internal space of water purifiers also brings numerous technical challenges, especially in models with heating functions, where heat management has become a major concern. Since the heating module generates high temperatures during operation, improper layout can lead to localized heat accumulation, affecting not only the stability and lifespan of surrounding electronic components but also potentially causing thermal aging of the water system due to heat conduction or radiation, and even impacting the accuracy of the water temperature and the user experience. Therefore, current water purifier designs not only require efficient arrangement of functional components within limited space but also need to address the heat concentration issues caused by the compact layout, improving the overall reliability, safety, and ease of maintenance. This research direction is of great significance for promoting high-performance, long-life, and optimized user experience in water purifiers.

[0004] A search revealed that patent CN219640438U provides a combined air purifier and heater. Its support frame includes a low-temperature structure mounting area and a high-temperature structure mounting area surrounding the low-temperature structure mounting area and located at the edge of the support frame. The power adapter is installed in the low-temperature structure mounting area, and the electrical control box and / or heating unit are installed in the high-temperature structure mounting area. This design achieves a separation of the high-temperature and low-temperature areas, which helps to reduce the temperature rise of the power adapter and even the entire machine, and improves the safety of use. However, there is still room for further optimization, and the industry has different approaches to the functional integration and layout of the machine body. Utility Model Content

[0006] 2. Technical Solution To achieve the above objectives, the technical solution provided by this utility model is as follows: The present invention relates to a water purifier, comprising a support frame, an installation area formed inside the support frame, a hot water outlet at the rear end of the support frame, and a heating element, a water circuit board, and an insulation box arranged sequentially from back to front in the installation area along the front-back length of the machine body. The inlet end of the heating element is connected to the outlet end of the insulation box, and the outlet end of the heating element is connected to the inlet end of the insulation box and the hot water outlet of the machine body respectively.

[0007] Furthermore, an electrical control frame is provided at the top of the support frame, and an electrical control module or adapter (240) is installed on the electrical control frame; the support frame forms an inner mounting area below the electrical control frame.

[0008] Furthermore, the front end of the supporting frame has a front plate, on which the adapter or electronic control module is mounted on the front side of the front plate away from the inner mounting area.

[0009] Furthermore, the electronic control frame extends along the length of the machine body, and at least part of the electronic control frame covers the length of the water channel plate 2 extending below.

[0010] Furthermore, it also includes a purification module. The supporting frame includes a purification frame and a functional frame arranged side by side along the left and right width direction of the body. The purification module is installed on the purification frame, and the heating element, water circuit board 2 and insulation box are all distributed in the inner installation area of ​​the functional frame.

[0011] Furthermore, the purification frame includes a filter cartridge frame and a pump mounting frame distributed along the height of the machine body. Inside, a filter element and a booster pump are respectively installed in a horizontally arranged manner. A purification water circuit board that matches the filter element is installed at the rear end of the purification frame.

[0012] Furthermore, the pump mounting bracket has a placement opening on the side facing the functional frame for inserting the booster pump, and the functional frame has a mounting panel on the side facing the purification frame. The mounting panel is connected to the purification frame and covers at least a portion of the placement opening.

[0013] Furthermore, a reversing valve is also provided above the heating element within the functional framework. The outlet end of the heating element is connected to the inlet of the reversing valve. The first outlet of the reversing valve is connected to the water inlet of the insulation box, and the second outlet of the reversing valve is connected to the hot water outlet above.

[0014] Furthermore, the mounting panel on the side of the functional frame facing the purification frame has an opening area with a thickness that extends through it. The water channel plate is at least partially embedded in the opening area and is detachably connected to the purification frame.

[0015] Furthermore, the water inlet is located at the top of the insulation box, and the water outlet is located at the bottom of the insulation box. Both the water inlet and the water outlet are located on the rear side of the insulation box, near the water circuit board.

[0016] Furthermore, the electronic control frame is located at the rear end of the functional frame, and the top of the functional frame forms an upper window at the front of the electronic control frame, which can expose at least part of the area of ​​the lower insulation box.

[0017] Furthermore, it also includes a base, with a water collection area at the rear end of the base. Behind the water collection area, facing the rear end of the machine body, there are two partitions, one and two, forming an isolation area that is isolated from the water collection area. The height of partition two is higher than that of partition one.

[0018] 3. Beneficial effects Compared with the prior art, the technical solution provided by this utility model has the following advantages: (1) The water purifier of this utility model separates the heating element and the heat preservation box at the front and rear ends of the machine body, and sets a water circuit board 2 between the two, forming an alternating layout of main high temperature zone, low temperature zone and secondary high temperature zone inside the machine body, which greatly avoids the 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.

[0019] (2) The water purifier of this utility model has the electronic control module installed at the top of the machine body, which helps to achieve water and electricity separation, avoid the risk of water ingress, and uses the electronic control frame to separate it from the inner installation area below, so that the electronic control module is relatively independently distributed and separated from the high-temperature components in the lower installation area, further reducing heat transfer and ensuring service life and stability.

[0020] (3) The water purifier of this utility model uses the front panel to separate the heat preservation box and the adapter, which reduces heat transfer and heat concentration. The adapter is located at the front of the machine body, which is more conducive to direct heat dissipation to the outside of the machine body. The adapter and the electrical control module are both located on the outside of the inner installation area, which also facilitates the separation and routing of the wires inside the machine body, ensuring the separation of strong and weak currents, and further improving the reliability and stability of the system operation.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0026] The present invention will be further described below with reference to the embodiments.

[0027] Example Combination Figures 1-11 As shown, this embodiment provides a water purifier, including a support frame, an inner mounting area formed inside the support frame, a hot water outlet 212 provided at the rear end of the support frame, and a heating element 210, a water circuit board 220 and a heat preservation box 230 arranged sequentially from back to front in the inner mounting area along the front-back length direction of the machine body. The inlet end of the heating element 210 is connected to the water outlet end 233 of the heat preservation box 230, and the outlet end of the heating element 210 is connected to the water inlet end 231 of the heat preservation box 230 and the hot water outlet 212 of the machine body respectively.

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

[0031] Furthermore, preferably, an electrical control frame 202 is provided at the top of the support frame, and the electrical control module (not shown in the attached drawings) is installed on the electrical control frame 202, specifically in the electrical control mounting area enclosed by the electrical control frame 202; the support frame forms an inner mounting area below the electrical control frame 202. Alternatively, the adapter 240 can be installed on the electrical control frame 202. In this embodiment, the electrical control module is specifically installed at the top of the body, which helps to achieve water and electricity separation, avoids the risk of water ingress into the electrical control module, and uses the electrical control frame 202 to separate it from the inner mounting area below, distributing the electrical control module relatively independently and isolating it from the high-temperature components in the lower mounting area, further reducing heat transfer to the electrical 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 electronic 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.

[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 them. Furthermore, placing the adapter 240 at the very front of the machine body facilitates direct heat dissipation to the outside of the machine. Furthermore, 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. 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. In practice, the installation positions of the adapter 240 and the electronic control module can be interchanged; that is, the electronic control module can be mounted on the front side of the front plate 204, and the adapter 240 can be mounted on the electronic control frame 202.

[0034] In practice, the heating element 210 can be specifically installed 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 hot 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] The water purifier in this embodiment is further preferably integrated with a purification function, and a purification module is provided inside the machine. In this case, as a preferred design 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] Regarding the specific design of the purification frame 100, further, it combines... Figure 1 and Figure 3 As shown, the purification frame 100 includes a filter cartridge frame 110 and a pump mounting frame 120 distributed along the height of the machine body. Internally, a horizontally arranged filter element and a booster pump 122 are respectively installed. A purification water circuit board 130, which is fitted to the filter element, is installed at the rear end of the purification frame 100. The purification water circuit board 130 integrates valve groups, pump group components, etc., required for filtration and purification (details omitted), including connection to the booster pump 122, which pumps pre-filtered water into the RO membrane filter element. The top of the purification water circuit board 130 has a water inlet area, including a pure water outlet 131, a raw water inlet, and a wastewater outlet. The pure water outlet 131 can be used as a pipeline machine interface, etc. The purification water circuit board 130, together with the installed filter element and booster pump 122, forms a basic universal module for filtration and purification.

[0037] More specifically, in practice, a dual-filter structure can be set up. The purification frame 100 has filter cartridge holders 110 at both the top and bottom along the height direction. The top filter cartridge holder 110 houses a first filter cartridge 111, which combines pre-filters and post-filters. The bottom filter cartridge holder 110 houses an RO membrane filter cartridge. A pump mounting bracket 120 is located between the two filter cartridge holders 110. The pump mounting bracket 120 encloses a booster pump mounting area 121, and the booster pump 122 is horizontally mounted within the booster pump mounting area 121. Specifically, combined with... 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.

[0038] Furthermore, combining Figures 4 to 6 As 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.

[0039] In this embodiment, the hot 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 normal temperature water outlet, etc., which, together with the interface area at the top rear end of the purification frame 100, form an interface concentration area at the top rear end of the body, which facilitates the centralized distribution of pipelines.

[0040] In practice, the outlet end of the heating element 210 needs to be connected to the insulation box 230 and the hot water outlet 212 respectively. This can be achieved by using a reversing valve 203, combined with... Figure 1 and Figure 2As 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 231 of the insulation box 230, and the second outlet of the reversing valve 203 is connected to the hot 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 hot water outlet 212, the shortest pipeline design between the outlet end of the heating element 210 and the hot water outlet 212 is achieved. The heated hot water can reach the hot water outlet 212 directly via 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.

[0041] In this embodiment, the machine body is equipped with 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 groups, pump groups and other components required for the purification function. The second water circuit board 220 is mainly distributed inside the functional skeleton 200, located between the heating body 210 and the insulation box 230. The second water circuit board 220 mainly integrates various valve groups, pump groups, sensor detection and other components required for the purified water circuit system. For example, there is a diaphragm pump 1 to pump water in the insulation box 230 to the heating body 210, a diaphragm pump 2 to directly send the purified water to the heating body 210, and an outlet valve for controlling the water output, etc., which will not be described in detail. Water circuit board 220 and purification water circuit board 130 are vertically distributed, and their independent arrangement 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.

[0042] 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.

[0043] 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.

[0044] 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.

[0045] 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.

[0046] The following further elaborates on the insulated box 230 in this embodiment. (In conjunction with...) Figure 10 As shown, preferably, the first water inlet 231 is located at the top of the insulation box 230, and the second water outlet 233 is located at the bottom of the insulation box 230. Both the first water inlet 231 and the second water outlet 233 are located on the rear side of the insulation box 230 near the second water circuit board 220. This not only saves pipe length and promotes integrated distribution, but also forms a convenient operating area between the rear side of the insulation box 230 and the second water circuit board 220, facilitating wiring and maintenance. Furthermore, the top of the insulation box 230 is also provided with a second water inlet 232, which is internally connected to the pure water outlet 131 of the purification module, allowing purified pure water to be directly and quickly replenished into the insulation box 230. Both the second water inlet 232 and the first water inlet 231 are located on the rear side of the top of the insulation box 230. This embodiment adopts a top-inlet and bottom-outlet water design, which not only facilitates the water pump to fully extract water from the tank, but also enables automatic internal circulation of cold and hot water within the tank, ensuring uniform water temperature mixing. In addition, the insulated tank 230 is equipped with an exhaust vent on its top.

[0047] Furthermore, the top of the insulated box 230 is equipped with a water level detector 234, specifically a water level detection probe. The water level detector 234 is located on the front side of the insulated box 230 away from the water circuit board 220. The insulated box 230 is generally made of metal insulation material. To ensure detection accuracy, it is preferable to mount the water level detector 234 on the detection mounting plate 235 and extend it into the box. The detection mounting plate 235 is fixed to the front side of the top of the insulated box 230. The top of the insulated box 230 is also equipped with an exhaust port, and the bottom may also be equipped with a drain port, so that water can be directly discharged from the machine body when needed by opening the drain port. A temperature sensor is also installed inside the insulated box 230.

[0048] Furthermore, combining Figure 2 As shown, the electronic control frame 202 is preferably located closer to the rear end of the functional frame 200. An upper window 201 is formed at the top of the functional frame 200 in front of the electronic control frame 202. The upper window 201 can expose at least a portion of the lower insulation box 230, more precisely, the area where the lower water level detector 234 is located. The upper window 201 can serve as a maintenance window, facilitating the replacement and maintenance of the detection components of the insulation box 230 without disassembling the entire frame.

[0049] Combination Figure 11 As shown, in this embodiment, the bottom of the machine body also has a base 300. The rear end of the base 300 is provided with a water collection area 303. Behind the water collection area 303, facing the rear end of the machine body, there are two partitions in sequence: a first partition 304 and a second partition 305. A separation area 306 is formed between the first partition 304 and the second partition 305, which is isolated from the water collection area 303. The height of the second partition 305 is higher than the height of the first partition 304.

[0050] Specifically, in this embodiment, a water collection area 303 is set in the rear part of the machine body, corresponding to the distribution area of ​​the second water circuit board 220 and the purification water circuit board 130. This can effectively collect water leakage from the water pipes inside the machine body. A leak detector is also installed inside the machine body to detect the risk of leakage. The base 300 includes a bottom wall 301. External stiffening plates 302 are respectively provided on both sides of the rear end of the bottom wall 301 in the length direction. The external stiffening plates 302 in the length direction, together with the first partition 304 and the second partition 305 in the width direction, form an isolation area 306. The first partition 304 in the front is lower in height, and the second partition 305 in the rear is higher in height. This arrangement can effectively avoid the problem of frequent false alarms of the leak detector caused by a small amount of water accumulation during pipe disassembly and assembly. When a small amount of water accumulates at the rear of the machine, it can be blocked by partition 304 and prevented from entering the water collection area 303, thus avoiding false alarms. When the machine does leak, the water can quickly overflow partition 304 and enter the water collection area 303, ensuring timely and accurate detection. Partition 305 is higher, thus preventing water from flowing directly out of the machine from the rear.

[0051] The water purifier in this embodiment, through the rational layout of high-temperature and low-temperature components, ensures a compact and miniaturized body structure while effectively avoiding internal heat concentration issues, thus guaranteeing the reliability and stability of the machine. Furthermore, the parallel design of the functional frame 200 and the purification frame 100 allows for the differentiated and centralized arrangement of different functional components, enhancing the versatility and adaptability of different frames and further improving the space utilization of each component, thereby meeting users' higher requirements for a compact and miniaturized machine.

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.
