Description

Technical Field

[0001] The utility model relates to the technical field of water purification equipment, in particular to an embedded water purifier. Background Art

[0002] A water purifier is a device that deeply filters and purifies water to produce or deliver warm, hot, or cold water. Embedded water purifiers are increasingly popular among consumers because they can be completely embedded in cabinets or walls, forming a harmonious whole with the overall kitchen.

[0003] During the use of a water purifier, it is necessary to regularly or irregularly check the filter cartridge's filtration status and replace it promptly. Failure to do so can affect the purifier's effectiveness. Embedded water purifiers are completely embedded in a cabinet or wall, so checking or replacing the filter cartridge often requires moving the entire unit and disassembling it. This inconvenient operation reduces the user experience. Even when the filter cartridge is replaced by a professional, disassembly and replacement can still be difficult.

[0004] A search revealed patent authorization publication number CN 220695015 U, which discloses a built-in water dispenser. The application includes a built-in housing and a modular filtration device, located within the housing, comprised of several modular filter cartridge assemblies. A removable cover is provided at the connection between the housing and the modular filtration device to facilitate filter cartridge replacement within the modular filter cartridge assembly, which may be a single or at least two sets. The removable cover can be magnetic, snap-fit, or hinged. This application facilitates filter cartridge replacement within the modular filter cartridge assembly by providing a removable cover at the connection between the housing and the modular filtration device. However, since the removable cover is located on the customer-facing side, it is susceptible to accidental contact or opening by children out of curiosity. Furthermore, the removable cover is completely independent of the front panel of the water dispenser. After filter cartridge replacement, whether the removable cover is reinstalled or not does not affect the customer's ability to insert a water container and operate the water dispenser normally. This may cause the detachable cover to be not installed and reset in time after the filter element is replaced, and the filter element installation port is exposed to the outside, which is unsightly and foreign matter can easily enter the interior of the body.

[0046] Example 1

[0047] Combine Figure 1 、 Figure 2 、 Figure 8 、 Figure 9 and Figure 10 The embedded water purifier of this embodiment includes a housing formed by an upper panel 4 (shown in the figure), a side panel 3 (the other side panels are not shown), and a bottom plate (not shown). The housing houses a frame, a water tank, and other water treatment components. The water treatment components and the housing comprise a body 10, which serves as the main body of the water purifier.

[0048] It should be understood that for embedded water purification equipment, only the front end faces the customer, so a shell is set to cover the internal components. The most important function is aesthetics and protection. It is actually feasible not to have the upper panel 4 and the side panel 3.

[0049] The front side of the body 10 is provided with a spout 5 for discharging purified water from the body 10 through the outlet of the spout 5. A water receiving platform 6 is provided for placing a water receiving container, which receives the water discharged from the spout 5. A water collection box 8 is provided for collecting water released from the water receiving container placed on the water receiving platform 6. The water collection box 8 comprises a box body with a water storage chamber, the top of which is provided with an opening.

[0050] The middle portion of the front door 1 is recessed rearward to form a water receiving chamber 14 for placing a water container. The water receiving platform 6 is provided on the lower sidewall of the water receiving chamber 14. A water spout inlet 138 is provided on the wall of the water receiving chamber 14. When the front door 1 is closed, the water outlet of the water spout 5 can enter the water receiving chamber 14 through the water spout inlet 138 and face the water receiving platform 6. Water on the surface of the water receiving platform 6 can flow through a water collection channel 139 into a water collection box 8 provided on the body 10.

[0051] The front door 1 is movably mounted on the front side of the housing 10. Specifically, a front cover 7 is provided on the front side of the housing 10. The front cover 7 can cover the internal components of the housing. The front door 1 can cover the front cover 7, making the front side of the front cover 7 invisible. The front cover 7 is provided with a receiving cavity 72 formed by being recessed into the housing 10. When the front door is closed, the front door 1 can cover the receiving cavity 72 of the housing 10.

[0052] The faucet 5 is mounted on the housing 10, near the upper side of the accommodating cavity 72. A filter cartridge assembly opening 721 is provided on the wall of the accommodating cavity 72. The filter cartridge assembly opening 721 is positioned on the housing 10 so that when the front door 1 is closed, the front door 1 completely covers the filter cartridge assembly opening 721. When the front door 1 is opened, the filter cartridge can be completely removed from the filter cartridge assembly opening 721.

[0053] The housing 10 is provided with a filter cartridge mounting seat 9, which is configured to mount and secure a filter cartridge. The mounting seat 9 is equipped with a filter cartridge mounting barrel 91 for linearly inserting the filter cartridge. One end of the filter cartridge cavity 911 of the cartridge mounting barrel 91 communicates with the filter cartridge assembly port 721. The filter cartridge is inserted into the cartridge mounting barrel 91 through the filter cartridge assembly port 721, and can be removed from the cartridge mounting barrel 91 through the filter cartridge assembly port 721. The filter cartridge is connected to the various waterways of the waterway plate, filtering water entering the water inlet, discharging the filtered pure water, and discharging wastewater generated by the filter cartridge.

[0054] Furthermore, the filter cartridge mounting seat 9 is fixedly arranged in the housing, and the filter cartridge mounting barrel 91 is arranged inside the housing 10 along the front-to-back direction. The filter cartridge assembly port 721 and the filter cartridge mounting barrel 91 are coaxially arranged, and the filter cartridge is laterally inserted into the filter cartridge mounting barrel 91 through the filter cartridge assembly port 721; or is laterally pulled out from the filter cartridge mounting barrel 91 through the filter cartridge assembly port 721. In this way, when the filter cartridge needs to be replaced, the user only needs to pull the filter cartridge outward from the filter cartridge mounting seat 9 from the front side of the housing, and then insert the replacement filter cartridge into the filter cartridge mounting seat 9 from the front side of the housing. This method of replacing the filter cartridge does not require the entire machine to be pulled out from the cabinet or wall, nor does it require the filter cartridge mounting seat 9 and the filter cartridge to be pulled out from the machine cavity together. The filter cartridge can be replaced as a whole. The operation is simple and convenient, which can greatly reduce the tediousness of filter cartridge replacement and is conducive to improving the user experience. In addition, the filter element mounting seat 9 is not pulled out from the machine cavity together with the filter element, that is, the filter element mounting seat 9 is fixedly set in the machine cavity. In this way, when the user replaces the filter element by himself, it can also effectively avoid interference with the pipelines and other components set on the filter element mounting seat 9 due to user's misoperation (such as damaging the pipelines), which is beneficial to improving the reliability and service life of the whole machine.

[0055] Example 2

[0056] Combine Figure 3-Figure 5 In this embodiment of an embedded water purifier, the filter element mounting opening 721 is perpendicular to the wall of the accommodating chamber 72 and extends from the wall of the accommodating chamber 72 toward the interior of the housing 10, forming an extension portion 7211 that protrudes from the wall of the accommodating chamber 72. The outer diameter of the extension portion 7211 matches the inner diameter of the filter element mounting barrel 91, and the extension portion 7211 is configured to be inserted into the interior of the filter element mounting barrel 91.

[0057] A plurality of fixing members 75 are provided on the peripheral cavity wall of the extension portion 7211. Correspondingly, a plurality of structures cooperating with the fixing members 75 are also provided on the periphery of the filter element mounting cylinder 91 of the filter element mounting seat 9. Specifically, they are fixing holes 92 in this embodiment. After the extension portion 7211 is inserted into the filter element mounting cylinder 91, the cavity wall of the accommodating cavity 72 is fixed by cooperating with the fixing members 75 and the fixing holes 92, which can ensure that the filter element mounting seat 9 and the front cover plate 7 are reliably fixed, and the filter element can be smoothly inserted into the filter element mounting cylinder 91.

[0058] The filter element can be cylindrical, cubic or other appropriate shapes. The shape of the filter element installation cylinder 91 for linear plug-in filter element should be compatible with the shape of the filter element. For example, when the filter element is cylindrical, refer to Figure 1 and Figure 2 , the filter element mounting cylinder 91 should also preferably be cylindrical.

[0059] The filter element mounting seat 9 is provided with at least one filter element mounting barrel 91, and typically two or three filter element mounting barrels 91 are provided. The position and number of the filter element mounting openings 721 on the wall of the accommodating chamber 72 are adapted to the filter element mounting barrels 91. The filter element mounting barrels 91 can accommodate different or non-identical filter elements; the filter element mounting barrels 91 can be arranged vertically, horizontally, or in other suitable arrangements.

[0060] Each filter element installation cylinder 91 in the filter element installation seat 9 corresponds to a filter element, and different filter element installation cylinders 91 are inserted with different or non-identical filter elements; the filter elements that can be used include but are not limited to RO reverse osmosis filter elements, pre-filter elements, post-filter elements, and pre- and post-composite filter elements.

[0061] Specifically in this embodiment, the filter element mounting seat 9 is provided with two horizontally arranged filter element mounting cylinders 91. The filter element mounting cylinders 91 are arranged in parallel up and down on one side of the water purifier. The two filter element mounting cylinders 91 are respectively provided with an RO reverse osmosis filter element and a front and rear composite filter element.

[0062] It is worth noting that during the service life of the water purifier, the filter element is the key to ensuring water quality and requires regular maintenance. Compared with other equipment failures, the replacement of the filter element has the characteristics of being user-operable and relatively high in frequency. In view of the design feature that the embedded water purifier is completely embedded in the cabinet or wall, with only one side facing the user, this embodiment places the filter element horizontally inside the compartment, and the filter element assembly port 721 is set on the front cover 7. The filter element is inserted into the filter element mounting seat 9 from the front side of the housing from the filter element assembly port 721 inward, and can be pulled out from the filter element assembly port 721 laterally outward for replacement as a whole, which ensures that both professionals and users can replace the filter element more conveniently. At the same time, the filter element, rack, water tank and other components in the compartment are covered by the front cover 7 to prevent the user from opening the front door 1. The components in the compartment are clearly visible, affecting the user's visual experience and improving the safety of equipment use.

[0063] The design concept of this embodiment is mainly to allow the front door 1 to cover the front cover 7, so that the front face of the embedded water purifier facing the customer has a simple and elegant appearance. In theory, the front door 1 and the front cover 7 can be connected by magnetic, snap-on or other movable connection methods to achieve the overall opening and closing of the front door 1 relative to the front cover 7. However, from the perspective of connection stability and ease of operation, this embodiment preferably provides a hinge 12 on one side of the front door 1, and the front door 1 is connected to the front cover 7 through the hinge 12. The function of the hinge 12 is mainly to enable the front door 1 to be opened from the side away from the hinge 12 and rotated relative to the front cover 7. When the front door 1 is open relative to the front cover 7, the filter element can be pulled out from the filter element assembly port 721 for replacement. When the front door 1 and the front cover 7 are in a closed state, the front door 1 can cover the front cover 7, especially the filter element assembly port 721 provided on the front cover 7.

[0064] It should be understood that the front door 1 does not necessarily cover the front cover 7 completely and 100% of the time; it can also cooperate with other components to cover the front cover 7. Specifically, in this embodiment, a front panel 2 is provided at the front end of the housing, above the front door 1. This front panel 2 is fixed to the upper end of the front cover 7 and partially covers the front cover 7. The front panel 2 can be used to accommodate components such as a display screen, a touch control panel, or indicator lights. The front panel 2 and front door 1 can be designed as an integral whole or as a separate part, which is completely feasible in terms of technology. Only in this embodiment, a separate part is used.

[0065] The hinge 12 can theoretically be set at the upper end, lower end, left end and right end of the front door 1. Based on the user's usage habits, this embodiment sets the hinge 12 at the left end of the front door 1, that is, the user opens the front door 1 from the right side.

[0066] Example 3

[0067] Combine Figure 6-Figure 7In the embodiment of the present invention, an embedded water purifier is designed with an integral opening and closing front door 1 , which includes a front panel 11 , a hinge 12 , and a rear panel 13 . The hinge 12 is arranged on the sides of the front panel 11 and the rear panel 13 .

[0068] The rear plate 13 is symmetrically provided with two concave first concave portions 131 and second concave portions 132. An opening extending from top to bottom is formed between the first concave portion 131 and the second concave portion 132. The upper end of the opening is a faucet inlet 138, and the faucet 5 extends through the faucet inlet 138; so that when the front door 1 and the front cover plate 7 are in a closed state, the faucet 5 is located on the outside of the front door 1.

[0069] The lower end of the opening formed between the first inner recess 131 and the second inner recess 132 is a water collection channel 139, which together with the bottom plates of the first inner recess 131 and the second inner recess 132 forms a trapezoidal water receiving area that is wide on the outside and narrow on the inside, and a water receiving platform 6 is fixed on the water receiving area; a box body mounting portion 71 is provided at the bottom of the front cover 7, and the water collection box 8 is installed in the box body mounting portion 71; when the front door 1 and the front cover 7 are in a closed state, the water collection platform 6 is located above the water collection box 8, and the water collection box 8 is in an invisible state. When the front door is opened, the water collection box 8 can be taken out from the box body mounting portion 71.

[0070] In order to further improve the user experience, this embodiment provides a hidden handle 136 on the upper side of the rear panel 13. The hidden handle 136 can also be provided on the right side or the lower side of the rear panel 13. This embodiment still provides the hidden handle 136 on the upper side of the rear panel 13 from the perspective of conforming to the user's usage habits.

[0071] A first magnetic block 135 and a plug-in 137 are also provided on the side of the rear panel 13 away from the hinge 12, wherein the first magnetic block 135 cooperates with the second magnetic block 74 provided at the corresponding position of the front cover 7, and shock-absorbing pads 134 are provided on the upper and lower sides of the first magnetic block 135. In this embodiment, the plug-in 137 is provided at the lower corner of the shock-absorbing pad 134. The plug-in 137 has a conical structure and is magnetic. It cooperates with the Hall sensor provided in the socket 73 on the front cover 7 to determine whether the front door 1 is completely closed. The provision of the first magnetic block 135 and the plug-in 137 can ensure that the front door 1 is reliably closed and prevent it from opening in the event of accidental touching. The shock-absorbing pad 134 can play a role in reducing shock and noise when closing the front door 1.

[0072] In this embodiment, a strip-shaped installation groove 133 is provided on the upper side of the rear plate 13 , and a light strip is installed in the installation groove 133 to create an atmosphere when receiving water or to provide lighting when receiving water at night.

[0073] The above description is only a preferred embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or direct / indirect application in other related technical fields are included in the patent protection scope of the present invention.
