Description

Technical Field

[0001] This utility model relates to the field of household appliance technology, and in particular to a water purifier shell and a water purifier having the same. Background Technology

[0002] As living standards improve, people are paying more attention to the health and quality of their drinking water, and more and more families are equipping themselves with water purifiers to improve their water usage. Generally speaking, the main body of a water purifier consists of the casing and the filter cartridges inside. The filter cartridges perform deep filtration and purification of the water according to its usage requirements. Water purifiers are not only suitable for areas with severe tap water pollution, but also for under-sink water purification in homes, effectively filtering residual chlorine from tap water and improving the taste of the water.

[0003] Currently, water purifiers on the market often suffer from problems such as complex assembly processes leading to low production efficiency, inconvenient panel disassembly and assembly causing users to be unable to quickly replace filter cartridges, and poor shell structural strength, making them prone to deformation. Furthermore, when assembling the protective outer shell of the water purifier, it is generally done by slipping the shell onto the internal unit, while ensuring that the inlet and outlet of the water circuit board can protrude from one side of the shell after assembly for easy connection of external PE pipes. However, this assembly method inevitably requires that the inlet and outlet of the shell not restrict the shell during the insertion process; otherwise, it will affect the smooth assembly of the shell and the unit, and may even cause damage to the shell or the internal unit.

[0004] A search revealed patent number CN217431036U, which discloses an easy-to-assemble water purifier. This application discloses a water purifier comprising a front shell, a middle shell, a rear shell, and a purification component. One side of the purification component is detachably connected to one side of the front shell. The purification component is inserted into the middle shell via one side, and the two are detachably connected. The rear shell is detachably connected to the other side of the middle shell. This application simplifies the assembly process and shortens assembly time by minimizing the number of parts and modularizing them. However, this application uses a quick-connect water pipe on the middle shell to connect to the external pipe and the water inlet on the filter cartridge mounting base. This connection takes considerable time during assembly. Furthermore, while the quick-connect water pipe directly connects to the water inlet on the filter cartridge mounting base, avoiding limitations on the outer shell assembly, the internal water circuit function of the water purifier is very limited, restricting its use.

[0031] 3. Beneficial effects

[0032] Compared with existing known technologies, the technical solution provided by this utility model has the following significant advantages:

[0033] (1) The water purifier shell of this utility model has the water inlet and outlet of the water circuit board facing upwards and is provided with separate water inlet and outlet through plates. An opening is reserved on the middle shell corresponding to the water inlet and outlet position. The water inlet and outlet through plates can be detachably installed in the opening area and directly snapped into the middle shell at the opening through the hole. In the process of fitting the shell into the internal body, the water inlet and outlet are avoided from restricting the assembly of the shell, which can ensure the smooth assembly of the shell and the body and avoid damage to the shell or the internal body (such as the water inlet and outlet). The water inlet and outlet through plates are easy to install and remove, which can save assembly time.

[0034] (2) The water purifier shell of this utility model has multiple ribs on the middle shell, and the ends of the ribs are reserved with slots. The inner side of the front panel has a flange on all four sides, which engages with the rib slots of the middle shell for positioning. When assembling the water purifier, the front panel is first positioned and installed with the middle frame, and then the shell is moved along the front and back direction and fitted onto the outside of the machine body. The installation and positioning of the middle shell and the front panel can be achieved through the cooperation of the rib slots and the flange of the front panel, which is convenient to operate.

[0035] (3) A water purifier shell of the present invention has multiple symmetrically arranged protrusions at the connection between the filter element assembly hole and the filter element assembly cylinder, which are higher than the inner wall of the filter element assembly cylinder. The multiple protrusions support the filter element to prevent the filter element from moving down under the action of gravity, which would cause uneven gap between the filter element and the filter element in the filter element assembly cylinder cavity. This helps to pull out or insert the filter element from the side of the water purifier when replacing the filter element, making it convenient for users to disassemble and replace the filter element themselves.

[0036] (4) A water purifier shell of the present invention, in the process of fitting the body, which is mainly composed of a middle frame, a water circuit plate, a filter element and a booster pump, into the middle shell, the first limiting groove and the second limiting groove cooperate with the convex rib, so that the middle frame and the water circuit plate can move along the convex rib in the middle shell, which facilitates the assembly of the body and the middle shell and can minimize damage to the shell or the body.

[0037] (5) The water purifier shell of this utility model has multiple support feet at the bottom of the middle frame and multiple first through holes at the bottom of the middle shell. The support pad enters the middle shell through the first through holes to support the support feet, so that there is a gap between the support feet and the inner wall of the middle shell, so that the weight of the machine body is mainly concentrated on the support feet and the middle shell as a whole is not stressed. In addition, the ribs also serve as reinforcing ribs, which can ensure that the shell is not easily deformed.

[0038] (6) In this utility model, a water purifier is designed with a vertical water circuit board as a divider. The filter element and the booster pump are located on the same side of the water circuit board, while the functional components that are connected to the water circuit are uniformly installed on the other side of the water circuit board. This achieves water and electricity separation and reduces the risk of short circuits in functional components when the filter element is replaced or when the filter element interface leaks. At the same time, the functional components are located between the water circuit board and the back cover. When the water purifier needs to be inspected and repaired, only the back cover needs to be removed. It is not necessary to disassemble all the components of the water purifier, which makes inspection and repair more convenient. Attached Figure Description

[0058] Example 1

[0059] Combination Figure 1 This embodiment of a water purifier includes an outer shell 1 comprising: a dust cover 11, a front panel 12, a middle shell 13, a rear cover 14, and inlet / outlet water inlets / outlets 15. Wherein:

[0060] The middle shell 13 is a frame-shaped shell that extends from front to back. The main body, assembled from the middle frame 2, water circuit board 3, filter element 4, and booster pump 5, is fitted inside the middle shell 13. The middle shell 13 can protect various components such as the water circuit board 3, filter element 4, and booster pump 5. Wherein:

[0061] The middle frame 2 is fitted into the installation chamber formed inside the middle shell 13. The middle frame 2 mainly serves a supporting function, and the same number of filter element assembly cylinders 21 are provided for the corresponding filter element 4. In addition, the water circuit plate 3 and the booster pump 5 are connected to the middle frame 2.

[0062] The water channel plate 3 is set on one side of the middle frame 2, and its interior forms a structure resembling... Figure 12 The diagram shows multiple water channels 32 with different functions. The water channel plate 3 is vertically arranged and parallel to the rear cover plate 14. (Combined) Figure 11 The water circuit board 3 is provided with an element distribution area 33 on its exterior. Functional elements 34 that are fluidly connected to the water circuit 32 are installed in the element distribution area 33. The element distribution area 33 is located on the side of the water circuit board 3 near the rear cover plate 14.

[0063] Combination Figure 1The rear cover plate 14 is provided with a plurality of second studs 141 along its circumference. In this embodiment, a plurality of third studs 36 are provided circumferentially on the side of the water channel plate 3 near the rear cover plate 14, and a third stud 36 is also provided on the side of the middle frame 2 below the rear cover plate 14. The second studs 141 and the third studs 36 are threadedly connected to achieve a detachable connection between the rear cover plate 14, the water channel plate 3, and the middle frame 2. The second studs 141 and the third studs 36 not only serve a fixing function, but also leave space between the rear cover plate 14, the water channel plate 3, and the middle frame 2 for setting up functional elements 34.

[0064] It is worth noting that the connection of the rear cover plate 14 can also be achieved by detachably connecting the rear cover plate 14 to the water channel plate 3 or by detachably connecting the rear cover plate 14 to the middle frame 2.

[0065] For example, the functional components 34 include an inlet solenoid valve, a concentrate solenoid valve, a reflux solenoid valve, an adjustable solenoid valve, a check valve, a TDS probe, a pressure switch, etc. These functional components 34 are used to adjust various functions when the water circuit 32 is flowing.

[0066] The filter element 4 is inserted into the filter element assembly cylinder 21 of the middle frame 2 and is fluidly connected to the water passage 32, and is configured to filter the raw water flowing into the water purifier.

[0067] In specific implementation, multiple filter elements 4 are preferably set. The raw water is filtered by the combination of multiple filter elements 4, which facilitates the achievement of different levels and types of filtration needs and achieves better water treatment effect. The multiple filter elements 4 are fluidly connected through water passage 32, and the flow relationship of water between the filter elements 4 is adjusted by functional element 34. In this embodiment, the filter elements 4 include a composite filter element and an RO filter element. The composite filter element includes a pre-filter element and a post-filter element. The water treated by the pre-filter element first flows into the RO filter element, and after being treated by the RO filter element, it flows into the post-filter element for further treatment.

[0068] A booster pump 5 is also located in the mounting chamber and is fluidly connected to the water passage 32. The booster pump 5 is configured to increase the pressure of the water in its downstream pipeline so that water with a certain pressure passes through the filter element 4.

[0069] In this embodiment, the functional element 34, which is connected to the water circuit, is uniformly installed on one side of the water circuit plate 3, realizing the separation of water and electricity. This reduces the risk of short circuit of the functional element 34 when the filter element 4 is replaced or when the filter element interface leaks. At the same time, the functional element 34 is located between the water circuit plate 3 and the rear cover plate 14. When the water purifier needs to be inspected and repaired, only the rear cover plate 14 needs to be removed. It is not necessary to disassemble all the components of the water purifier, which makes inspection and repair more convenient.

[0070] Combination Figure 7 and Figure 8The middle shell 13 is provided with a plurality of protruding ribs 132 along its inner sidewall in the circumferential direction, and the protruding ribs 132 extend along the front-rear direction of the middle shell 13; the end of the protruding rib 132 forms a groove 133 with the inner wall surface of the middle shell 13.

[0071] The aforementioned ribs 132 primarily function as reinforcing ribs, thereby increasing the structural strength of the middle shell 13 and effectively protecting the internal components of the middle shell 13. Secondly, in conjunction with... Figure 9 The front panel 12 has a flange 121 on its inner periphery. The flange 121 cooperates with the slot 133. The front panel 12 and the middle shell 13 are connected by the flange 121 being inserted into the slot 133.

[0072] The front panel 12 is provided with a plurality of first studs 124 along its circumference, and the middle frame 2 is provided with a plurality of bolts 24 on the side near the front panel 12. The bolts 24 are threadedly connected to the first studs 124, thereby realizing the detachable connection between the middle frame 2 and the front panel 12.

[0073] When assembling the water purifier, the front panel 12 is first positioned and installed with the middle frame 2, and then the middle shell 13 is moved along the front and back direction and fitted onto the outside of the machine body. The middle shell 13 and the front panel 12 can be installed and positioned by the cooperation of the slot 133 at the end of the protruding rib 132 and the flange 121 of the front panel 12, which is convenient to operate.

[0074] The front panel 12 is provided with the same number of filter element assembly holes 122 corresponding to the filter element 4. Each filter element assembly hole 122 is a barrel-shaped structure adapted to the filter element assembly cylinder 21; the filter element assembly hole 122 is connected to the filter element assembly cylinder 21, and the filter element 4 is inserted into the filter element assembly cylinder 21 through the filter element assembly hole 122. At the junction of the filter element assembly hole 122 and the filter element assembly cylinder 21, there are protrusions 123 that are higher than the inner wall of the filter element assembly cylinder 21. Multiple protrusions 123 are symmetrically arranged along the circumferential inner wall of the filter element assembly hole 122, preferably 6 or 8.

[0075] Multiple protrusions 123 support the filter element 4 to prevent it from shifting downwards under gravity, which would cause uneven gaps between the filter element assembly cylinder 21 and the filter element 4. This also helps to remove or insert the filter element 4 from the side of the water purifier when replacing it.

[0076] The dust cover 11 is magnetically attached and detached from the front panel 12, allowing for convenient and quick assembly and removal. After removing the dust cover 11, the user can install or remove the composite filter and RO filter into the filter assembly cylinder 21 through the filter assembly hole 122, facilitating self-installation and replacement of the composite and RO filters. When the dust cover 11 is installed, it covers the filter assembly hole 122, the composite filter, and the RO filter, preventing foreign objects from entering the water purifier and improving its overall appearance.

[0077] Combination Figure 2 and Figure 3 An opening 131 is provided on the side of the middle shell 13 near the water channel plate 3. Exemplarily, the opening 131 is a sunken opening, that is, a part of the opening 131 is lower than the top shell wall of the middle shell 13. The opening 131 is closed by a water inlet / outlet through plate 15, and the water inlet / outlet assembly 31 of the water channel plate 3 extends out of the outer shell 1 through the water inlet / outlet through plate 15.

[0078] In this embodiment, the inlet and outlet ports 311 of the water circuit board 3 are set facing upwards, and a separate inlet and outlet water passage plate 15 is provided. An opening 131 is reserved on the middle shell 13 at the position corresponding to the inlet and outlet ports 311. The inlet and outlet water passage plate 15 can be detachably installed in the area of ​​the opening 131 and directly snapped into the middle shell 13 at the opening 131 through the hole. During the process of fitting the middle shell 13 into the internal body, the inlet and outlet ports 311 are avoided from restricting the assembly of the middle shell 13, which can ensure the smooth assembly of the middle shell 13 and the body and avoid damage to the middle shell 13 or the internal body (such as the inlet and outlet ports).

[0079] Example 2

[0080] As a preferred embodiment, combined with Figure 6 In this embodiment, the water circuit board 3 is provided with an inlet / outlet assembly 31 on its top. The inlet / outlet assembly 31 includes an inlet / outlet 311, a fixing post 312, a screw 313, and an interface 314. The opening of the inlet / outlet 311 faces upward and is fluidly connected to the water circuit 32. Raw water flows in through the inlet, and the water treated by the combination of composite filter and RO filter can flow through the water circuits 32 with different functions respectively, and finally be discharged through the outlet. In this embodiment, four water outlets are provided side by side on the top of the water circuit board 3, namely raw water inlet, wastewater outlet, pure water outlet, and domestic water outlet.

[0081] A fixing post 312 is provided on the side of the inlet / outlet 311. The fixing post 312 is threadedly connected to the screw 313, so that the interface 314 and the inlet / outlet 311 can be detachably connected.

[0082] Combination Figure 4 and Figure 5The inlet and outlet water perforation plate 15 is provided with the same number of perforations 151 corresponding to the inlet and outlet water inlet 311, and the interface 314 extends out of the inlet and outlet water perforation plate 15 through the perforations 151.

[0083] The inlet and outlet water inlet plate 15 is provided with a first buckle 152, a second buckle 153 and a guide member 154 along its circumference. The first buckle 152 is configured to engage with the protruding rib 132 provided on the inner wall of the middle shell 13, that is, the hook of the first buckle 152 is engaged with the uppermost protruding rib 132 on the side wall of the middle shell 13.

[0084] The second latch 153 is configured to engage with the inner wall surface of the middle shell 13, specifically, in conjunction with Figure 3 On the middle shell 13, a plurality of second through holes 135 are provided at the edge of the opening 131. The second buckle 153 is inserted into part of the second through hole 135, and the hook of the second buckle 153 is engaged with the inner wall surface of the middle shell 13.

[0085] The guide member 154 is configured to guide when the inlet / outlet water through plate 15 is engaged with the middle shell 13. Specifically, part of the guide member 154 is inserted into other second through holes 135, and part of the guide member 154 abuts against the inner wall of the middle shell 13 or the rear cover plate 14 to achieve guidance.

[0086] The design of the inlet / outlet water penetration plate 15 relative to the middle shell 13 in this embodiment makes the installation and disassembly of the inlet / outlet water penetration plate 15 convenient and can save assembly time.

[0087] Example 3

[0088] Combination Figure 1 In this embodiment, the middle frame 2 is provided with a plurality of first limiting grooves 25 on the side near the front panel 12, combined with Figure 11 The water channel plate 3 is provided with a plurality of second limiting grooves 35 along its circumference; combined with Figure 13 and Figure 14 The first limiting groove 25 and the second limiting groove 35 cooperate with the protruding rib 132. Figure 14 The example only shows the cooperation between the second limiting groove 35 and the protruding rib 132 (the cooperation structure between the first limiting groove 25 and the protruding rib 132 is similar), so that the middle frame 2 and the water channel plate 3 can move along the protruding rib 132 in the middle shell 13.

[0089] During the process of fitting the main body, which is mainly composed of the middle frame 2, water channel plate 3, filter element 4 and booster pump 5, into the middle shell 13, the first limiting groove 25 and the second limiting groove 35 cooperate with the protruding rib 132 to allow the middle frame 2 and water channel plate 3 to move along the protruding rib 132 in the middle shell 13. This facilitates the assembly of the main body and the middle shell 13 while minimizing damage to the outer shell 1 or the main body.
