[0001] The utility model relates to the field of electrical appliances, in particular to household water purifier electrical equipment, specifically a water purifier. Background Art

[0002] As people's quality of life improves, their awareness of drinking water safety has gradually increased. Household water purifiers integrate water purification and drinking water, and have the advantages of convenience, safety and health, and have been rapidly promoted. With the development of technology, water purifiers have been continuously updated with product functions according to different application scenarios. For example, from a simple water purification function, it has developed into a water storage, heating, cooling, sparkling water making and other functions. In addition, according to different household usage areas, it has developed into under-counter, countertop, wall-mounted, and water purifiers that can meet both countertop and wall requirements to meet the installation and use needs of different users.

[0003] With the development of water purifier technology, on the one hand, it is required to have more functions and improve user experience. On the other hand, it is required to be as compact as possible so that it can be placed on the countertop, under the kitchen or wall-mounted to occupy less space. At the same time, the commonality of various components of different series of water purifiers should be improved as much as possible to reduce the number of accessories, reduce costs and increase adaptability. In existing water purifiers, the water channels in the machine body are mostly distributed to the filter element, water tank, heating body, ice tank and other functional components through the water channel plate to adapt to the complex water channel distribution control, especially the filter element is often connected to the water channel of the water channel plate through the filter element seat. However, in existing water purifiers, the filter cartridge seat and the waterway plate are usually integrally injection molded or connected by fasteners. For example, the Chinese patent publication number is CN112357980 A, the publication date is February 12, 2021, and the name is: A water purifier with a fixed filter cartridge and automatic filter cartridge ejection structure. Two filter cartridge fixing assemblies are provided on the right side of the waterway plate. A filter cartridge interface is provided in the filter cartridge fixing assembly for installing the filter assembly. Multiple filter cartridge seats in the filter cartridge fixing assembly are fixed on the waterway plate, which requires the waterway plate to reserve a filter cartridge seat installation position. The waterway plate has a large shape and occupies a large space. It is often difficult to install in a compact water purifier, or the pipeline is difficult to inspect 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 requires the waterway plate to adapt to different filter cartridges, reducing versatility and greatly increasing the number of accessories. Utility Model Content

[0004] The purpose of the utility model is to provide a water purifier to solve the problem that in the prior art, the filter seat and the waterway plate in the water purifier are usually integrally injection molded or connected by fasteners, resulting in a larger shape of the waterway plate, occupying a larger internal space of the water purifier and having low versatility.

[0005] In order to achieve the above-mentioned purpose, the utility model provides a water purifier, comprising a frame, a waterway plate, a waterway plate and a filter element seat; wherein the filter element is used to filter and purify the water entering the waterway plate, and is installed in the frame; the waterway plate is used for waterway distribution inside the water purifier, and is installed in the frame; the waterway plate has a front side and a back side, and a water inlet is provided on the front side; the filter element seat has a waterway interface; the filter element is installed on the filter element seat, and the filter element can be connected with the waterway of the waterway plate through the filter element seat;

[0007] This solution separates the filter element seat from the waterway plate, which effectively reduces the overall area occupied by the waterway plate and reduces the internal space occupied by the water purifier, making the water purifier more compact. The filter element seat is designed independently, and only the filter element seat needs to be replaced according to the needs of different types of filter elements, without changing the waterway plate. 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 upper and lower vertical spaces of the rack, which facilitates their installation and interconnection in the rack.

[0008] Further optimization is made to the installation position of the waterway plate. The waterway plate cavity is arranged close to the bottom of the frame in the height direction. The waterway plate cavity is connected to the outside of the frame through the loading port opened at the bottom of the frame. The waterway plate is loaded into the waterway plate cavity of the frame through the loading port. In this way, the waterway plate is easy to install in the frame, and each solenoid valve installed on the waterway plate is located in the waterway plate cavity, which has a certain protective effect. At the same time, the waterway plate is located at the bottom of the frame, which can effectively prevent accidental water seepage from affecting other components, especially electrical components, and improve safety. Preferably, the water inlet on the waterway plate is only arranged on the front side to facilitate the waterway plate to be connected in the frame. There is no water inlet on the back side, which is convenient for the water purifier to install the bottom plate, and the structure is compact.

[0009] The layout of the waterway plate in the rack is further optimized, and the waterway plate cavity is located at the front side of the rack in the horizontal direction; the length direction of the waterway plate is along the length direction of the rack, and the width direction of the waterway plate is along the width direction of the rack. In this arrangement, the width of the waterway plate can be designed to be roughly equivalent to the width of the rack, and the length direction occupies less space, making full use of space and making the layout more compact.

[0010] In order to facilitate the inspection of the connection reliability between the waterway plate and other components and to facilitate maintenance, an inspection port connected to the waterway plate cavity is provided on the frame above the waterway plate and around the waterway plate cavity. More preferably, the inspection port is provided on at least one side of the frame in the width direction, or both sides in the width direction, or the inspection port is also provided on the front side in the length direction of the frame, which greatly improves the inspection range and convenience, and also reduces the weight of the whole machine to a certain extent.

[0011] As a further optimization and improvement of the water purifier, the front of the waterway plate is kept roughly horizontal with the placement surface at the bottom of the water purifier; the support seat is provided with a support surface for supporting the filter cartridge seat, and the support surface is roughly parallel to the front of the waterway plate. The support seat and the waterway plate are arranged vertically opposite each other, which makes it easier to connect the two with a pipe. On this basis, the connecting pipe between the waterway plate and the filter cartridge seat is a straight pipe with a certain hardness, preferably a pipe fitting made of PE or TPU. During installation, a section of the connecting pipe can be inserted into the waterway plate first, and then the waterway plate can be installed into the waterway plate cavity. The connecting pipe has a certain hardness, and the other end can be directly inserted into the pipe joint on the support seat for quick installation, thereby greatly improving the quickness of connection between the waterway plate and the support seat.

[0012] As a further optimization and improvement of the water purifier, in the frame, a partition is arranged above the waterway plate and extends along the length direction of the frame, and the two sides of the partition have a filter element cavity for installing a filter element and a pump cavity for installing a booster pump, respectively. The support seat is located on the side where the filter element cavity is located and is connected to the partition, and the pump cavity is connected to the waterway plate cavity. The space in the width direction of the frame above the waterway plate is divided into two by the partition, which can meet the installation space requirements of the filter element and the booster pump at the same time, make full use of the space, and facilitate the connection of the booster pump to the waterway plate. At the same time, the booster pump is located in a relatively independent space, which can effectively reduce the operating noise. Preferably, the upper side of the filter element cavity and the side relative to the partition are open, or the pump cavity is open on the side relative to the partition, which is convenient for the installation of the filter element and the booster pump. More preferably, a booster pump is installed in the pump cavity on the frame, the water inlet and outlet of the booster pump are downward, and are connected to the waterway of the waterway plate through a connecting pipe. A connection method similar to that between the filter element seat and the waterway plate can be adopted, which is convenient for connection.

[0034] The present invention will be described in detail with reference to the accompanying drawings. What is described here is only a preferred embodiment of the present invention, and those skilled in the art can think of other ways to implement the present invention based on the preferred embodiment, and other ways also fall within the scope of the present invention.

[0035] like Figure 1 and Figure 2 As shown, this embodiment shows a water purifier, which can be a countertop type, an under-counter type or a wall-mounted type. Here, the under-counter type water purifier is taken as an example. The frame 100, the waterway plate 300, the waterway plate 300 and the filter element seat 600 installed in the frame 100 are retained, and other internal structures are omitted. Among them, the filter element 200 is used to filter and purify the water entering the inside, and it is installed in the frame 100; the waterway plate 300 is used for water distribution inside the water purifier, and it is installed in the frame 100; the filter element seat 600 is used as the installation base of the filter element 200, and the filter element 200 can be detachably installed on the filter element seat 600.

[0036] The under-counter water purifier in this example is in the shape of a rectangular block as a whole, so that it can be placed under the counter. Its front-to-back direction is the length direction, and its left-to-right direction is the width direction. The water inlets and outlets are located on the rear side. 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. 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, which reduces versatility and greatly increases the number of accessories. The present scheme 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 to solve this problem. The following is a description of the installation method of the waterway plate 300. Figure 1 and Figure 2 The under-counter water purifier shown illustrates a specific solution of the utility model.

[0037] Figure 3 and Figure 4 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; Figure 7 and Figure 8 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.

[0038] The waterway plate 300 has a front side and a back side. A water inlet 310 is provided on the front side. There are multiple water inlets 310, which can be installed with quick-connect plugs to facilitate pipeline connection, or to install various control solenoid valves or detection components, such as TDS detection sensors. As a more preferred method, the water inlet 310 of the waterway plate 300 is only provided on the front side, so that the waterway plate 300 can be connected to the frame 100. There is no water inlet 310 on the back side, which is convenient for installing the base plate at the bottom of the water purifier, and the structure is compact. There is a waterway plate cavity 130 in the frame 100. The waterway plate 300 is installed in the waterway plate cavity 130, and the front side of the waterway plate 300 faces the top of the water purifier, and the back side faces the bottom, so that the waterway plate 300 can be connected from the top. 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 cartridge seat 600 of the water purifier from above 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 cartridge seat 600 through the connection pipe 630. The number of openings of the support seat 120 is determined according to the type of filter cartridge 200 installed on the filter cartridge 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.

[0039] 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.

[0040] Combination Figure 3-Figure 5 and Figure 7-Figure 8As 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.

[0041] In this embodiment, the waterway plate cavity 130 is arranged at the front side of the length direction of the frame 100 in the transverse direction, 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 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.

[0042] 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 rear 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.

[0043] like Figure 7 and Figure 8 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.

[0044] Combined with Figures 6 to 8 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 PE, TPU material pipe fitting, etc. The external interface on the filter element seat 600 is installed with a pipe joint 640, and the pipe joint 640 extends into the waterway plate cavity 130 through the opening on the support seat 120 or around it, 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, a section of the connecting tube 630 can be first inserted into the waterway plate 300, 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 connection speed 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.

[0045] 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.

[0046] Combination Figure 1-Figure 4 and Figure 7-Figure 8 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.

[0047] 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. As an under-counter water purifier, the upper side of the water purifier is limited by the countertop space, 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. There is also an upper chamber 113 with a larger volume 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.

[0048] Combination Figure 1-Figure 2 and Figure 9-10 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.

[0049] like Figure 1 , Figure 3 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.

[0050] 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-counter water purifiers.
