Description

Technical Field

[0001] The utility model relates to the technical field of water purifiers, and more specifically to a large-flux under-sink water purifier. Background Art

[0002] Under-the-sink water purifiers are often installed in the cabinets under the kitchen. When in use, you can get filtered clean water by turning on the faucet, which is very quick to operate. However, because it is installed under the cabinet, and the kitchen sink is generally embedded downward into the cabinet, the space for placing the under-the-sink water purifier is very limited. The common under-the-sink water purifiers on the market are small in size and generally only provide direct drinking water at room temperature, or have a heating function. With the improvement of living standards, people have higher requirements for water purifiers, hoping that they can not only provide direct drinking pure water, but also hot water and ice water at the same time. But obviously, the increase in functions will inevitably lead to an increase in the overall size of the water purifier. For example, for a countertop water purifier with full hot and cold purification functions, its size is difficult to install under the kitchen environment.

[0003] In practice, the width between the cabinet and the sink is relatively small, and because a drain elbow needs to be arranged under the sink, the installation space of the under-kitchen water purifier is further limited. If the drain elbow is staggered and the water purifier is placed away from the sink, it will not only take up space in other areas of the cabinet, but will also inevitably lead to the need to significantly lengthen the pipe connecting the under-kitchen water purifier to the faucet. In addition to increasing the cost of the pipe, the overly long pipe will also affect the placement of items in the cabinet. In summary, the under-kitchen water purifiers on the market are currently limited by the installation space, making it difficult to balance the richness of the functions of the water purifier and the operability of the installation volume. In addition, the kitchen water environment has certain particularities. First of all, the kitchen uses a large amount of water and has a demand for large flow and fast water discharge. In addition, the water quality requirements for water use are different in different environments. For example, the water quality requirements for cleaning water and drinking water are completely different. This also puts forward better requirements for the overall design of the under-kitchen water purifier, which has become a factor affecting the competitiveness of the product.

[0004] For example, the patent with publication number CN212632001U discloses an under-kitchen water purifier, which is flat as a whole and can be flexibly and conveniently installed in the narrow space of the cabinet. The pipe connected to the water faucet can be made very short, saving the increase of pipes, but the design has a single function and does not have cooling and heating functions. The patent with publication number CN215480097U discloses an under-kitchen water purifier and heat all-in-one machine, which only adds a heating function to the original filtration and cannot meet user needs. The patent with publication number CN220951240U discloses an under-kitchen water purifier with cooling function, which is equipped with a heating and cooling system and can produce hot water or ice water. The overall layout can also be used for installation in a small space under the kitchen, but the design adopts an instant heating and drainage method, which inevitably leads to a small water flow rate and is not suitable for a large water flow environment in the kitchen. The patent with publication number CN220135721 U discloses an under-kitchen water heater, which rationally plans and utilizes space to achieve miniaturization and integration of the entire machine; it adopts the coordinated heating of a preheating tank and an instant heating module, and the water is preheated in the preheating tank to the preheating temperature and then heated by the instant heating module, which can be heated to the required temperature more quickly, and helps to achieve a large flow of water, but this design is also lacking in comprehensive functionality. Utility Model Content

[0005] 1. Technical problems to be solved by the utility model

[0006] In view of the problem that the installation space of under-kitchen water purifiers in the prior art is limited and the volume of the whole machine is strictly required, it is difficult to balance the user's demand for the rich functionality of the under-kitchen water purifier. The utility model intends to provide a large-flow under-kitchen water purifier, which, through reasonable layout design, ensures comprehensive functions and can be applied to the under-kitchen installation environment. At the same time, it helps to achieve large-flow waterproofing and adapt to the special water use environment of users' kitchens.

[0007] 2. Technical solution

[0008] In order to achieve the above-mentioned purpose, the technical solution provided by the utility model is:

[0009] The utility model discloses a large-throughput kitchen-type water purifier, comprising: a frame; a filter element for filtering and purifying incoming water; a heating module for heating the filtered purified water; it should be noted that the frame also includes a clean water tank, which is located at the upper rear part of the front-to-back direction of the water purifier; a partition is provided in front of the clean water tank, which extends in the front-to-back direction and divides the front area of ​​the clean water tank into two side areas in the left-right direction; a booster pump is installed in one side area, and a filter element is installed in the other side area; under the frame A support seat is provided at the bottom, and the filter element seat can be detachably installed on the support seat; a water circuit plate is provided under the support seat; the filter element includes at least two groups of filter elements, and the water circuit interfaces of several groups of filter elements are respectively connected to the water inlets on the water circuit plate through connecting pipes; a water inlet, a hot water outlet and a normal temperature water outlet are provided on the rear side of the frame along the front and rear direction of the water purifier, the water inlet is used to connect the pre-filtration water source, the hot water outlet is connected with the water outlet of the heating module, and is used to discharge the purified hot water separately, and the normal temperature water outlet is connected with the water outlet of the clean water tank, and is used to discharge the purified normal temperature water.

[0010] The utility model adds a clean water tank to the under-sink water purifier to effectively store purified water. When water is needed, the stored purified water is directly discharged, which can effectively increase the drainage flow and drainage speed, meet the large-volume water demand of the kitchen, and the clean water tank is arranged at the top of the water purifier to effectively ensure sufficient water pressure. On the basis of adding a clean water tank, in order to further meet the large-volume water demand of the kitchen and the different water quality requirements of the kitchen, the filter element in the utility model includes at least two groups of filter elements, and the multiple groups of filter elements are independently arranged, rather than using the conventional integrated filter element arrangement. Although the integrated filter element helps to simplify the volume to a certain extent, the service life of different filter elements is different, and the integrated filter elements must be replaced uniformly, which inevitably causes waste of resources or insufficient filtering effect. The utility model adopts the form of independent distribution of each group of filter elements, and each level of filter element can be replaced independently, which can effectively extend the overall service life of the filter element. More importantly, it can choose to use purified water with different filtration levels according to the filtering requirements of the water quality used. For example, three groups of filters including a pre-filter element, an RO filter element, and a post-filter element can be set in the rack. The first pipe and the second pipe are connected in parallel to the clean water outlet of the pre-filter element. The first pipe is connected to the RO filter element, and the second pipe is connected to the kitchen faucet, so that part of the water filtered by the pre-filter can be directly connected to the kitchen water faucet for washing water. At this time, the water only needs to be filtered once, without passing through the RO filter, and the filtration rate is greatly improved, and the water flow rate is large, which can meet the large flux requirements of clean water; and the other part of the water after the pre-filtration can continue to be connected to the RO filter and the post-filter for continued filtration to meet the drinking water quality requirements. The utility model can select the water quality filtration level by independently setting the multi-stage filter element, and select different water qualities according to the kitchen water demand, which not only meets the requirements for water quality, but also meets the demand for large flux water, and is very flexible. Alternatively, according to the volume design requirements of the water purifier, the pre-filter or the post-filter may be designed as a separate filter outside the water purifier, and connected to the water purifier through a pipeline.

[0011] In contrast, the independent distribution of multi-stage filter elements puts forward higher requirements on the spatial layout of the water purifier, especially on the compact installation of the filter element and the waterway plate. The utility model sets a support seat in the frame, installs the filter element seat above the support seat, and installs the waterway plate below the support seat. The waterway plate and the filter element seat are layered up and down, and the water outlet is connected by a connecting pipe to realize non-contact installation. This can effectively and significantly reduce the volume of the waterway plate, thereby realizing compact layout installation.

[0012] The high-throughput water demand in the kitchen is not only a high-throughput demand for clean water, but also a high-throughput discharge demand for drinking water quality. The utility model specially arranges different water outlets, and separates the hot water outlet and the normal temperature water outlet. That is, the water outlet of the heating module is connected to the hot water outlet separately, while the water outlet of the water purification tank is not connected to the heating module, but directly connected to the normal temperature water outlet, so that the normal temperature water in the water purification tank can be directly discharged when drinking normal temperature water without passing through the heating module. This can effectively increase the normal temperature water flow rate and realize high-throughput discharge.

[0013] As a preferred design for the installation of the filter element and the waterway plate, a waterway plate cavity is provided near the bottom of the frame in the height direction. The waterway plate cavity is located below the support seat. The waterway plate is installed in the waterway plate cavity, and the front of the waterway plate faces the top of the water purifier, and the back faces the bottom. The water inlet on the waterway plate is only provided on the front. The waterway interface of the filter element seat is connected to the water inlet of the waterway plate through a connecting pipe, so that the waterway plate can be connected to the pipe in the frame. There is no water inlet on the back, which is convenient for the water purifier to install the bottom plate. The structure is compact. The filter element seat and the waterway plate are designed to be split, and the overall occupied area of ​​the waterway plate is effectively reduced, and the internal space occupied by the water purifier is reduced, so that the water purifier can be designed more compactly; the filter element seat is designed independently, and according to the needs of different types of filter elements, only the filter element seat needs to be replaced, and the waterway plate does not need to be changed. The versatility of the waterway plate is enhanced, and the number of accessories can be reduced; at the same time, the filter element seat and the waterway plate are distributed in the vertical space up and down in the frame, which is convenient for them to be installed in the frame and connected to each other.

[0014] The arrangement orientation of the waterway plate in the frame is further optimized, the front-to-back direction of the water purifier is the length direction, the left-to-right direction is the width direction, and the length of the water purifier is greater than the width of the water purifier; the waterway plate cavity is located at the front side in the length direction of the frame in the transverse direction; the length direction of the waterway plate is distributed along the length direction of the water purifier, and the width direction of the waterway plate is distributed along the width direction of the water purifier. In this arrangement, the width of the waterway plate can be designed to be roughly equivalent to the width of the frame, and the length direction occupies less space, fully utilizing the space and making the arrangement more compact.

[0015] As one of the ways to distribute the filter elements, the filter element includes at least one group of filter elements installed in the rack, and a pre-filter arranged outside the rack. The pre-water inlet of the pre-filter is connected to the tap water pipe, the pre-filter has a pre-first water outlet connected to the kitchen faucet, and the pre-filter has a pre-second water outlet connected to the water inlet of the water purifier. By independently setting up the pre-filter, the large flux demand for kitchen clean water can be met, and it helps to streamline the internal structure of the water purifier and reduce the size of the equipment. The RO filter element and the post-filter element can be retained in the rack, or the RO filter element can be retained alone, etc., and it can be flexibly adjusted according to the filtering needs.

[0016] In order to improve the comprehensiveness of the functions of the under-kitchen water purifier, the frame also includes a refrigeration module, which is located at the lower rear part of the water purifier in the front-to-back direction and below the clean water tank. The heating module is also located below the clean water tank and between the filter element and the refrigeration module. Correspondingly, the water outlet of the refrigeration module is connected in parallel with the water outlet of the clean water tank and then connected to the normal temperature water outlet, which serves as the common outlet for normal temperature water and cold water.

[0017] As a structural optimization of the water tank, the water tank adopts a water tank structure with a rectangular cross section, and the length direction of the water tank is distributed along the length direction of the water purifier, and the width direction of the water tank is distributed along the width direction of the water purifier. The width of the water tank is basically the same as the width of the water purifier, so that the volume of the water tank is maximized in a limited space, and the large-capacity water storage meets the demand for large-volume water output. The capacity of the water tank in this solution can reach 6L. In order to optimize the installation of the water tank, the frame has a water tank accommodating cavity at the upper rear side of the front and rear direction of the water purifier. The water tank can be detachably placed in the water tank accommodating cavity, and the lower edge of the water tank accommodating cavity has a water tank bottom guard plate extending upward, which is supported on the outside of the water tank to enhance the support stability of the water tank, and is also conducive to enhancing the overall strength of the frame.

[0018] As a further enrichment of the functions of the under-kitchen water purifier, a filter element waste water outlet and a pipeline machine interface are provided on the rear side of the frame along the front-to-rear direction of the water purifier. The filter element waste water outlet is connected to the waste water outlet of the filter element for discharging waste water; the pipeline machine interface is connected to the clean water outlet of the filter element for connecting the pipeline machine.

[0019] Furthermore, a heat dissipation module is provided on the rear side of the refrigeration module along the front-to-back direction of the water purifier, and a heat dissipation channel communicating with the outside is opened on the outer shell of the water purifier. The heat dissipation channel corresponds to the rear side of the front-to-back direction of the water purifier, that is, the heat dissipation end and the external water inlet end of the water purifier in this solution are located on the same side, both facing the rear side of the front-to-back direction of the water purifier, and the connection space is utilized to ensure sufficient heat dissipation at the same time.

In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0052] The utility model is further described below in conjunction with embodiments.

[0053] Example

[0054] Combination Figure 1-Figure 19 As shown, a large-throughput under-sink water purifier of this embodiment includes: a frame 100; a filter element 200, which is used to filter and purify the incoming water; a heating module 810, which is used to heat the filtered clean water; in particular, it also includes a clean water tank 800, which is located at the upper rear position in the front-to-back direction of the water purifier; a partition 150 is provided in front of the clean water tank 800, and the partition 150 extends in the front-to-back direction and divides the front area of ​​the clean water tank 800 into two side areas in the left-right direction; a booster pump 400 is installed in one side area, and a filter element 200 is installed in the other side area; more specifically, a PCB controller 820 and a power adapter 821 are also installed in the area where the booster pump 400 is located, combined with Figure 3 As shown in the center position, the filter element 200 is installed in the right area in front of the clean water tank 800, and the PCB controller 820, the power adapter 821 and the boost pump 400 are located in the left area in front of the clean water tank 800. Specifically, the PCB controller 820 is horizontally placed in the upper part of the left area, the power adapter 821 and the boost pump 400 are vertically distributed below the PCB controller 820, and the power adapter 821 is located on the side of the PCB controller 820 closer to the clean water tank 800, and the boost pump 400 is located on the side of the PCB controller 820 away from the clean water tank 800.

[0055] In this embodiment, a support seat 120 is provided at the lower part of the frame 100, and the filter element seat 600 can be detachably installed on the support seat 120; a water circuit plate 300 is provided below the support seat 120; the filter element 200 includes at least two groups of filter elements, and the water circuit interfaces of several groups of filter elements are respectively connected to the water inlet 310 on the water circuit plate 300 through connecting pipes 630; in addition, a water inlet 716, a hot water outlet 715 and a normal temperature water outlet 717 are provided on the rear side of the frame 100 along the front-to-back direction of the water purifier, and the water inlet 716 is used to connect the pre-filtration water source, the hot water outlet 715 is connected to the water outlet of the heating module 810, and the normal temperature water outlet 717 is connected to the water outlet of the clean water tank 800.

[0056] In order to meet the large-volume water demand in the kitchen, this embodiment adds a clean water tank 800 to realize the water use process of first storing water and then draining water. Compared with the ready-to-use and filtered type, it can effectively improve the water outlet efficiency and water outlet flow rate, and has a large-volume drainage characteristic; by setting the hot water outlet 715 and the normal temperature water outlet 717 separately, drinking normal temperature water does not need to pass through the heating module 810, further increasing the normal temperature water outlet flux; in addition, the use of multiple groups of filter elements in a split type can directly connect the water after the pre-primary filtration to the large kitchen faucet, meeting the large-volume use demand of non-drinking water quality. However, the problem that must be considered at the same time is that the addition of a water tank already occupies a large internal space, and the split design of multiple filter cartridges will further occupy space. In existing water purifiers, the filter cartridge seat and the waterway plate are usually integrally injection molded or connected by fasteners, which means that the waterway plate must reserve a filter cartridge seat installation position. When multiple filter cartridges are present, the waterway plate has a large appearance and occupies a large space. It is often difficult to install in a compact water purifier, or the pipeline is difficult to repair after installation. At the same time, different types of filter cartridges are of different sizes, and the corresponding filter cartridge seats are also different, which also means that the waterway plate must be adapted to different filter cartridges, reducing versatility and greatly increasing the number of accessories. This solution adopts the form of multiple groups of filter cartridges being independently distributed in the water purifier. According to the traditional installation method of the waterway plate, multiple groups of filter cartridge seats must be reserved on the waterway plate for installation, which is completely unsuitable for under-kitchen installation requirements. In order to meet the large-volume drainage requirements under the kitchen, this embodiment makes improvements in the installation method of the waterway plate 300 and the connection method between the filter cartridge seat 600 and the waterway plate 300.

[0057] Fig.10 and Fig.11 This is a three-dimensional view of the water purifier after removing the booster pump 400 and the seat plate 500, showing the installation method of the waterway plate 300 and the connection method between the filter element seat 600 and the waterway plate 300; Fig.14 and Fig.15 It is a partial three-dimensional view of the frame 100 , and the installation positions of the filter element seat 600 and the waterway plate 300 on the frame 100 can be seen.

[0058] The waterway plate 300 has a front side and a back side, and a water inlet 310 is provided on the front side. There are multiple water inlets 310, which can be installed with a quick-connect plug to facilitate pipeline connection, or to install various control solenoid valves or detection components, such as TDS detection sensors, etc. As a better way, the water inlet 310 on the waterway plate 300 is only provided on the front side, so that the waterway plate 300 can be connected to the frame 100, and there is no water inlet on the back side, which is convenient for installing the bottom plate at the bottom of the water purifier, and the structure is compact. As a better way, the water inlet 310 on the waterway plate 300 is only provided on the front side, so that the waterway plate 300 can be connected to the frame 100, and there is no water inlet on the back side, which is convenient for installing the bottom plate at the bottom of the water purifier, and the structure is compact. The frame 100 has a waterway plate cavity 130, and the waterway plate 300 is installed in the waterway plate cavity 130, so that the front of the waterway plate 300 faces the top of the water purifier and the back faces the bottom, so that the pipe can be connected from the top of the waterway plate 300. In the frame 100, a support seat 120 is arranged above the waterway plate cavity 130, and the support seat 120 is configured to install the filter element seat 600 of the water purifier from the top of the support seat 120; at least one opening is provided on the support seat 120, or the frame 100 around the support seat 120 has openings, and the openings are configured so that the water inlet 310 of the waterway plate 300 can be connected to the filter element seat 600 through the connecting pipe 630. The number of openings of the support seat 120 is determined according to the type of filter element 200 installed on the filter element seat 600. The filter element seat 600 has a water channel interface. The filter element 200 can be detachably installed on the filter element seat 600. The filter element 200 can be installed on the support seat 120 from above the support seat 120. The filter element 200 can be connected to the water channel of the waterway plate 300 through the filter element seat 600. Specifically, the water channel interface of the filter element seat 600 is connected to the water inlet 310 of the waterway plate 300 through the connecting pipe 630.

[0059] In this solution, the filter cartridge seat 600 and the waterway plate 300 are designed to be split, and the overall area occupied by the waterway plate 300 is effectively reduced, and the internal space occupied by the water purifier is reduced, so that the water purifier can be designed to be more compact; the filter cartridge seat 600 is designed independently, and according to the needs of different types of filter cartridges, only the filter cartridge seat 600 needs to be replaced, and there is no need to change the waterway plate 300. The versatility of the waterway plate 300 is enhanced, and the number of accessories can be reduced; at the same time, the filter cartridge seat 600 and the waterway plate 300 are distributed in the upper and lower vertical spaces in the frame 100, which is convenient for them to be installed and connected to each other in the frame 100.

[0060] Combination Figure 10-12 and Figure 14-15As shown, the waterway plate cavity 130 is arranged near the bottom of the frame 100 in the height direction, and the waterway plate cavity 130 is connected to the outside of the frame 100 through the loading port 131 opened at the bottom of the frame 100, and the waterway plate 300 is loaded into the waterway plate cavity 130 of the frame 100 through the loading port 131. In this way, the waterway plate 300 is easy to install in the frame 100, and each solenoid valve installed on the waterway plate 300 is located in the waterway plate cavity 130, which has a certain protective effect; at the same time, the waterway plate 300 is located at the bottom of the frame 100, which can effectively prevent the accidental water seepage from affecting other components, especially electrical components, and improve safety. A plurality of connection holes 320 are arranged around the waterway plate 300, and corresponding fixing columns 132 are arranged on the frame 100 around the waterway plate cavity 130. After the waterway plate 300 is installed in the waterway plate cavity 130, screws are passed through the connection holes 320 and screwed into the fixing columns 132, so that the waterway plate 300 is fixed to the frame 100. Of course, the waterway plate 300 can also be installed on the frame 100 by other connection methods, such as snap-fitting or welding. At the same time, the front of the waterway plate 300 and the placement surface at the bottom of the water purifier, that is, the support surface of the water purifier, are kept roughly horizontal to facilitate its own installation and connection with the waterway of the filter element seat 600. Roughly horizontal means basically parallel to the support surface, and can be slightly tilted.

[0061] In this embodiment, the waterway plate cavity 130 is arranged at the front side in the length direction of the frame 100, the length direction of the waterway plate 300 is along the length direction of the frame 100, and its length accounts for about half of the entire length of the frame 100, and the width direction of the waterway plate 300 is along the width direction of the frame 100, and its width basically extends to the edge in the width direction of the frame 100, leaving only the edge of the frame 100 to limit the waterway plate 300 and ensure the strength of the frame 100. In this arrangement, the width of the waterway plate 300 can be designed to be roughly equivalent to the width of the frame 100, and there are retaining edges around to limit the waterway plate 300, and the length direction occupies less space, fully utilizes the space, and is more compactly arranged, and can also reduce the weight of the frame 100 to a certain extent.

[0062] In order to facilitate the inspection of the connection reliability between the waterway plate 300 and other components and to facilitate maintenance, an inspection port 160 connected to the waterway plate cavity 130 is provided on the frame 100 above the waterway plate 300 and around the waterway plate cavity 130. More preferably, the inspection port 160 is provided on at least one side in the width direction of the frame 100, or both sides in the width direction, or the inspection port 160 is also provided on the front side in the length direction of the frame 100, which greatly improves the inspection range and convenience, and also reduces the weight of the whole machine to a certain extent. In this embodiment, the inspection port 160 is provided on the left and right sides and the front side of the frame 100, so as to facilitate the all-round inspection of the waterway plate 300.

[0063] like Fig.14 and Fig.15 As shown, the support seat 120 is located on the upper side of the waterway plate cavity 130, and has a certain distance from the waterway plate 300 in the vertical direction, so that there is space in the waterway plate cavity 130 to accommodate the solenoid valve, detection components and other components installed on the front of the waterway plate 300. A support surface is provided on the upper surface of the support seat 120, and the filter element seat 600 is supported and installed on the support surface, and the support surface is generally parallel to the front of the waterway plate 300. Generally parallel can be parallel or with a slight angle. The support seat 120 and the waterway plate 300 are arranged vertically opposite each other, which makes it easier to connect the two with pipes. The filter element seat 600 can be supported and installed on the support surface of the support seat 120 by bolts, buckles, etc., to facilitate disassembly and assembly.

[0064] Combined with Figures 13 to 15 As shown, the waterway plate 300 and the filter element seat 600 are connected by water through the connecting pipe 630. Optimally, the connecting pipe 630 is a straight pipe with a certain hardness, such as a pipe made of PE or TPU. The external interface on the filter element seat 600 is installed with a pipe joint 640, which extends into the waterway plate cavity 130 through the through holes on or around the support seat 120, and the interface of the pipe joint 640 is directly opposite to the connecting hole 320 on the waterway plate 300, so that the connecting pipe 630 is a straight pipe with sufficient hardness, and can be directly plugged between the pipe joint 640 and the connecting hole 320 of the waterway plate 300, and is not easy to bend. During installation, one end of the connecting tube 630 can be inserted into the waterway plate 300 first, and then the waterway plate 300 can be installed into the waterway plate cavity 130. The connecting tube 630 has a certain hardness, and the other end thereof can be directly inserted into the pipe joint 640 on the support seat 120 for quick installation, thereby greatly improving the quickness of connection between the waterway plate 300 and the support seat 120. Here, the connecting tube 630 is required to have a hardness that can meet the requirement that when the waterway plate 300 with the connecting tube 630 inserted is installed into the waterway plate cavity 130, the other end of the connecting tube 630 can be directly inserted into the pipe joint 640 on the support seat 120, and the connecting tube 630 will not be bent.

[0065] In this embodiment, the support seat 120 includes a first bracket 121 with a first support surface 122 and a second bracket 124 with a second support surface 125. The first support surface 122 and the second support surface 125 are used to support and install a filter element 200 respectively, and there is a height difference between the two in the height direction of the water purifier. In this way, two different types of filter elements can be installed, and the height difference between the first support surface 122 and the second support surface 125 can be controlled to keep the upper end heights of the two filter elements relatively consistent, which is convenient for operation and understanding that the filter elements are installed in place. A first opening 123 is provided on the first support surface 122 of the first bracket 121, and a second opening 126 is provided on the second support surface 125 of the second bracket 124. The height of the first support surface 122 is higher than that of the second support surface 125. The first filter element 210 installed on the first filter element seat 610 on the first support surface 122 can be an activated carbon filter element, and the second filter element 220 installed on the second filter element seat 620 on the second support surface 125 can be an RO filter element. The volume of the RO filter element is larger than that of the activated carbon filter element, and has a longer life. At the same time, the RO filter element and the activated carbon filter element can be replaced separately according to their respective lifespans to improve utilization. The first external interface 611 of the first filter element seat 610 and the second external interface 621 of the second filter element seat 620 are connected to the connecting pipe 630 through the pipe joint 640 respectively. Filter element connecting columns 127 are provided on the first bracket 121 and the second bracket 124 around the first port 123 and the second port 126, so that the first filter element seat 610 and the second filter element seat 620 can be detachably installed on the first bracket 121 and the second bracket 124 by screws.

[0066] Combination Figure 8-Figure 12 and Figure 14-16 As shown, in the frame 100, a partition 150 is arranged above the waterway plate 300 and extends along the length direction of the frame 100. The two sides of the partition 150 are respectively provided with a filter element cavity 110 for installing the filter element 200 and a pump cavity 140 for installing the booster pump 400. The support seat 120 is located on the side where the filter element cavity 110 is located and is connected to the partition 150. The pump cavity 140 is connected to the waterway plate cavity 130. The filter element 200 is installed in the filter element cavity 110, and the booster pump 400 is installed in the pump cavity 140. The space in the width direction of the frame 100 above the waterway plate 300 is divided into two by the partition 150, which can meet the installation space requirements of the filter element 200 and the booster pump 400 at the same time, make full use of the space, and facilitate the booster pump 400 to connect to the waterway plate 300. At the same time, the booster pump 400 is located in a relatively independent space, which can effectively reduce the operating noise.

[0067] In this embodiment, the upper side of the filter cartridge chamber 110 and the side opposite to the partition 150 are open, that is, the right side of the frame 100 is open, the upper side is a top opening 115, and the right side is a right side opening 114. For an under-sink water purifier, the space above the countertop is limited, and the filter cartridge 200 is difficult to be directly loaded from the top. The top opening 115 and the right side opening 114 of the filter cartridge chamber 110 enable the filter cartridge 200 to be inserted into the filter cartridge chamber 110 from the right side opening 114, and force is applied through the top opening 115 to install the filter cartridge 200 in place in the filter cartridge seat 600. An upper chamber 113 with a larger volume is provided above the first filter cartridge chamber 111 and the second filter cartridge chamber 112 in which the filter cartridge 200 is installed in the filter cartridge chamber 110. A step is formed between the upper chamber 113 and the top surfaces of the first filter cartridge chamber 111 and the second filter cartridge chamber 112, so as to facilitate the disassembly and assembly of the filter cartridge 200.

[0068] Combination Figure 8-Figure 9 and Figure 16-Figure 17 As shown, a seat plate 500 is also provided in the filter element cavity 110. The seat plate 500 has a filter element chamber 510, which is open to the right to form a chamber side port 511. The upper side of the filter element chamber 510 has an upper side chamber 551 corresponding to the upper chamber 113. The bottom of the upper side chamber 551 is open, and a top plate 550 is provided around the opening. The top plate 550 is attached to the step surface formed between the upper chamber 113 and the top surfaces of the first filter element chamber 111 and the second filter element chamber 112. The left side of the filter element chamber 510 has a back plate 540, which includes a first back plate 541 and a second back plate 542, which match the shapes of the first filter element 210 and the second filter element 220, respectively. The bottom of the filter element chamber 510 has a horizontal plate 530, and the horizontal plate 530 is provided with a first insertion port 531 and a second insertion port 532. The first filter element 210 and the second filter element 220 are respectively inserted into the first insertion port 531 and the second insertion port 532 and connected to the first filter element seat 610 and the second filter element seat 620. A sealing plate 520 extends downward from the right side of the bottom of the filter element chamber 510, and the sealing plate 520 can cover the inspection port 160 on the right side of the frame 100. The design of the seat plate 500 can isolate the filter element 200 from a relatively closed installation space, which is convenient for the disassembly and assembly of the filter element 200 and more beautiful.

[0069] like Figure 8 , Fig.10 As shown, the pump chamber 140 is open on one side relative to the partition 150, i.e., the left side, to facilitate the installation of the filter element 200 and the booster pump 400. The booster pump 400 is fixed to the partition 150 in the pump chamber 140 by screws, and the water inlet and outlet of the booster pump 400 are downward, and are connected to the waterway of the waterway plate 300 through the connecting pipe 630, and can adopt a direct plug-in connection method similar to the filter element seat 600 and the waterway plate 300, which is convenient for connection and maintenance.

[0070] In summary, this solution separates the filter cartridge seat 600 from the waterway plate 300. The waterway plate 300 can be designed to be smaller, which reduces the internal space occupied by the water purifier, making the water purifier more compact. The filter cartridge seat 600 is independently designed to meet the needs of different types of filter cartridges. The filter cartridge seat 600, the booster pump 400 and the waterway plate 300 are easy to connect and maintain, and are particularly suitable for under-sink water purifiers.

[0071] By adopting the above-mentioned method, the present embodiment can flexibly select the distribution form of the filter element, such as: a three-stage filtration including pre-filter, RO and post-filter is arranged in the body, wherein the pre-water inlet of the pre-filter is connected to the tap water pipe, and the first pipe and the second pipe are connected in parallel at the clean water outlet of the pre-filter, the first pipe is connected to the RO filter element, and the second pipe is connected to the large kitchen faucet, so as to meet the large-volume direct drainage requirement. For example: only two-stage filtration including pre-filter + RO can be arranged in the body, and the post-filter is cancelled, and the clean water outlet of the pre-filter also has a first pipe connected to the large kitchen faucet, so as to meet the large-volume discharge requirement of the water after the pre-filter. Another example: refer to Figure 7 , two sets of filter elements, RO filter element and post filter element, can be installed in the frame 100, and the pre-filter 900 is set to be independent of the water purifier body, the pre-water inlet 901 of the pre-filter 900 is connected to the tap water pipeline, the pre-filter 900 has a pre-first water outlet 902 connected to the kitchen faucet, and the pre-filter 900 has a pre-second water outlet 903 connected to the water inlet 716 of the water purifier. In this way, the demand for large-flux drainage is met, and the volume of the water purifier can be simplified.

[0072] In this embodiment, the front-to-back direction of the water purifier is the length direction, and the left-to-right direction is the width direction. The water purifier is in the shape of a rectangular parallelepiped as a whole, and the length of the water purifier is greater than the width of the water purifier, preferably the length is not less than twice the width, so as to be installed under the kitchen. The water purifier has a shell 700 on the outside. In this embodiment, a large-capacity water purification tank 800 is used. The width direction of the water purification tank 800 is the left-to-right width direction of the water purifier, and the width of the water purification tank is the width of the water purification tank 800 after the shell 700 is covered on both sides of the width; the length direction of the water purification tank 800 is the front-to-back length direction of the water purifier, and the front-to-back length of the water purification tank 800 also basically occupies half of the front-to-back length direction of the water purification tank, and the water purification tank 800 adopts a rectangular box structure with basically the same cross-sectional area at the top and bottom, which maximizes the capacity of the water purification tank 800 in a limited space and ensures large-volume drainage. As a specific structural design of the clean water tank 800, as shown in the reference figure, the frame 100 has a water tank accommodating chamber 830 at the upper rear side in the front-to-rear direction of the water purifier. The clean water tank 800 can be detachably placed in the water tank accommodating chamber 830, and the lower edge of the water tank accommodating chamber 830 has a water tank bottom guard plate 801 extending upward. The water tank bottom guard plate 801 is supported on the outside of the clean water tank 800 to support the large-volume clean water tank 800. The top of the clean water tank 800 is detachably equipped with a water tank cover 803, and an exhaust overflow port 802 is provided on the upper side wall of the clean water tank 800. It serves as both exhaust and overflow. The exhaust overflow port 802 is separately connected to an overflow pipe to discharge to the outside of the machine body to ensure that the water pressure in the water tank is normal and even if overflow occurs, it is prevented from overflowing into the machine body and affecting the circuit safety.

[0073] In order to meet the richness of water use functions, the water purifier in this embodiment also includes a refrigeration module 850, which is located at the lower rear side of the water purifier in the front-to-back direction and below the clean water tank 800. The heating module 810 is also located below the clean water tank 800 and between the filter element 200 and the refrigeration module 850. The water outlet of the refrigeration module 850 is connected in parallel with the water outlet of the clean water tank 800 and is connected to the normal temperature water outlet 717. The normal temperature water outlet 717 serves as a common outlet for normal temperature water and cold water. Specifically, the water tank accommodating chamber 830 corresponds to a refrigeration accommodating chamber 840 below, and the refrigeration module 850 is located in the refrigeration accommodating chamber 840. The refrigeration module 850 is provided with a heat dissipation module 851 on the rear side facing the front-to-back direction of the water purifier, and the rear side of the housing 700 is provided with a heat dissipation channel 720 communicating with the outside world, so that the wiring direction of the water purifier is on the same side as the heat dissipation direction, and there is sufficient heat dissipation and wiring space.

[0074] In this embodiment, the frame 100 also has a filter element wastewater outlet 713 and a pipeline machine interface 714 on the rear side along the front-to-back direction of the water purifier. The filter element wastewater outlet 713 is connected to the wastewater outlet of the filter element 200 for discharging the filter element wastewater; the pipeline machine interface 714 is connected to the clean water outlet of the filter element 200 for directly connecting a portion of the filtered clean water to the pipeline machine. In practice, a pipeline connection plate 710 can be detachably installed on the frame 100 as a pipeline centralized distribution area. The water inlet 716, hot water outlet 715, normal temperature water outlet 717, filter element wastewater outlet 713 and pipeline machine interface 714 are all arranged on the pipeline connection plate 710. In addition, the pipeline connection plate 710 also serves as a connection area for the faucet signal connection line 711 and the power line 712, which is convenient for centralized pipe connection and wiring.
