Description

Technical Field

[0001] This utility model relates to the field of household appliances, and in particular to a water purifier. Background Technology

[0002] Traditional water purifier door panel assemblies often employ a circular magnet pairing design, where a circular neodymium magnet is installed on the door panel assembly, and another circular magnet or iron sheet is installed at a corresponding position on the base of the unit, achieving fixation through magnetic attraction. For example, in the intelligent direct drinking water purifier disclosed in Chinese utility model patent No. ZL202021794193.X (authorization announcement No. CN213488391U), a fixing plate 202 is fixedly installed at the center of the side of the door 201 away from the hinge, and a handle 203 is fixedly welded to the side of the fixing plate 202 away from the door 201. A magnetic strip 9 is fixedly installed at one end of the door 201 facing the main body 2, and multiple sets of circular magnets 901 are equidistantly arranged on one side of the main body 2 in conjunction with the magnetic strip 9. When the door 201 is closed, the magnetic strip 9 and the multiple sets of circular magnets 901 attract each other, preventing the door 201 from opening by itself.

[0003] However, this type of magnetic fixation solution has the following problems:

[0004] (1) The magnet polarity needs to be strictly matched (such as N / S pole alignment), otherwise it may lead to insufficient attraction or repulsion; (2) When the magnet is directly fixed to the base, a separate positioning structure needs to be set up, which is complicated and costly.

[0005] It is evident that the existing magnetic fixing solution for the door panel assembly of water purifiers needs further improvement. Summary of the Invention

[0006] The first technical problem to be solved by this utility model is to provide a water purifier with a magnetic door that is easy to assemble and has a reliable closing action.

[0007] The second technical problem to be solved by this utility model is to provide a water purifier with a magnetic door that is robustly assembled, in contrast to the prior art.

[0008] The technical solution adopted by this utility model to solve at least one of the above-mentioned technical problems is as follows: a water purifier, including a housing, characterized in that it further includes a strip-shaped magnetic metal plate, one side surface of which has a magnetic attraction surface for forming a magnetic attraction with a magnet on the door, and the housing is provided with a receiving groove for mounting the magnetic metal plate behind its surface liner, and the magnetic metal plate is installed in the receiving groove by means of a first end being detachably connected to and positioned by the receiving groove, and a second end being fixed to the receiving groove by fasteners, and the magnetic attraction surface of the magnetic metal plate extends vertically in the left and right direction when it is installed in the receiving groove.

[0009] Furthermore, the magnetic metal plate is bent into a U-shape along its length and includes a magnetic suction wall and a first connecting wall and a second connecting wall respectively connected to both ends of the magnetic suction wall. The outer surface of the magnetic suction wall forms the aforementioned magnetic suction surface, while the first connecting wall is embedded in the receiving groove. The free end of the second connecting wall has a mounting hole and is fixed to the receiving groove by the aforementioned fasteners. Designing the magnetic metal plate in a U-shape enhances the internal structural strength of the magnetic metal plate. Furthermore, it allows for a better formation of the magnetic suction surface, ensuring a stable magnetic attraction between the magnetic suction surface and the magnet of the door. Additionally, it allows for better detachable connection and positioning of the first end to the receiving groove, while the second end is fixed to the receiving groove by fasteners, ensuring a stable installation of the magnetic metal plate in the receiving groove.

[0010] Furthermore, the length of the first connecting wall is shorter than that of the second connecting wall. Since the second connecting wall is fixed to the receiving groove and the first connecting wall is embedded in the receiving groove, designing the length of the first connecting wall to be shorter than that of the second connecting wall is beneficial to improving the stability of the installation structure between the magnetic metal plate and the receiving groove.

[0011] Furthermore, the housing includes a frame with an open front, and the aforementioned faceplate is fixed to the edge of the front of the frame, with the front and back facing each other. A first insertion port and a second insertion port are respectively provided through the front and back of one side wall of the aforementioned receiving groove. Each insertion port is an elongated hole, and its size matches the cross-sectional size of the aforementioned magnetic metal plate.

[0012] During installation, the first end of the aforementioned magnetic metal plate passes sequentially through each insertion interface until the bends at both ends of the magnetic wall are located in the corresponding insertion interfaces, while the magnetic wall extends out of the receiving groove and is exposed on the front of the frame. By opening the first and second insertion interfaces, a stable connection between the first end of the magnetic metal plate and the receiving groove is achieved. Furthermore, the insertion allows the magnetic wall to extend out of the mounting groove and be exposed on the front of the frame, which not only allows for better placement of the magnetic surface in the desired orientation (extending vertically in the left-right direction), but also allows for better non-contact magnetic adsorption with the magnets of the door.

[0013] Furthermore, an installation channel is formed on the other side wall of the receiving groove along the depth direction of the receiving groove. When the magnetic metal plate is installed in the receiving groove, the first connecting wall is limited to the bottom of the receiving groove, while the second connecting wall is located in the opening of the receiving groove and covers most of the opening, and the mounting hole is directly opposite the installation channel. By limiting the first connecting wall to the bottom of the receiving groove, the first connecting wall is embedded in the receiving groove. By setting it in the installation channel and making the mounting hole on the second connecting wall directly opposite the installation channel, it is easy to fix the second connecting wall to the receiving groove with fasteners. The fact that the second connecting wall is located in the opening of the receiving groove and covers most of the opening allows the magnetic metal plate to be better accommodated in the receiving groove.

[0014] Furthermore, a mounting post protrudes from the outer surface of the frame. This mounting post extends along the depth direction of the receiving groove and has the aforementioned mounting channel. The mounting post, together with the mounting wall protruding from the outer surface of the frame or the wall at the corresponding location on the frame, forms the receiving groove. One side of the mounting post is located in the receiving groove. When the magnetic metal plate is installed in the receiving groove, the free end of the first connecting wall abuts against the mounting post and is thus limited. This allows for a better formation of the receiving groove on the frame, better implementation of the mounting channel in the receiving groove, and limitation of the first connecting wall at the bottom of the receiving groove by the abutment of the free end of the first connecting wall against the mounting post.

[0015] Furthermore, a groove matching the size of the magnetic wall is formed by recessing the accommodating slot at the corresponding location on the front edge of the frame. The first and second insertion interfaces are respectively located in this groove. With the magnetic metal plate installed in the accommodating slot, the magnetic wall is accommodated in this groove, and the magnetic surface of the magnetic wall is flush with the front edge. This prevents the magnetic wall from protruding from the front edge of the frame, facilitating the assembly of the frame and the faceplate, and also promoting the magnetic attraction between the magnetic surface and the magnet of the door.

[0016] Furthermore, the magnetic surface is square or rectangular with similar length and width. During installation, the magnetic metal plate can be placed horizontally or vertically depending on the different opening directions of the receiving slot, thus allowing for flexible installation of the receiving slot on the casing according to space requirements.

[0017] Furthermore, there are two magnetic metal plates, respectively disposed at the upper and lower ends of one side of the casing, and there are two receiving slots, each corresponding to one of the magnetic metal plates.

[0018] Furthermore, the magnetic metal plate located at the upper end of the casing is arranged horizontally along the vertical direction, and the first connecting wall is located below the second connecting wall. At the same time, the receiving groove corresponding to the magnetic metal plate extends vertically and opens upward.

[0019] A magnetic metal plate located at the lower end of the casing is horizontally arranged in the left-right direction, with the first connecting wall positioned inside the second connecting wall relative to the casing. Simultaneously, a receiving groove corresponding to the magnetic metal plate extends horizontally and opens outwards relative to the casing. This arrangement of two magnetic metal plates, with each plate attracting a corresponding magnet on the door, helps ensure the door closes securely and prevents accidental opening.

[0020] Furthermore, the magnetic metal plate is specifically a galvanized plate with magnetic properties.

[0021] Compared with existing technologies, the advantages of this invention are as follows: This invention utilizes the magnetism of the magnetic metal plate itself to form a non-contact magnetic attraction with the magnet of the door, achieving magnetic positioning of the door. Compared with magnets, the magnetic metal plate has a uniform magnetic distribution and does not require distinguishing between N / S poles. Therefore, replacing traditional magnets with magnetic metal plates eliminates the need for precise matching of magnetic poles during installation, reducing installation difficulty and the probability of errors, and lowering the production cost of the water purifier.

[0022] Furthermore, a magnetic attraction surface is provided on one side of the magnetic metal plate to ensure that the magnetic metal plate can form a strong magnetic attraction with the magnet, ensuring the reliability of the closing action. In addition, by extending the magnetic attraction surface vertically in the left and right directions, a reliable magnetic attraction between the magnetic attraction surface and the magnet of the door can be better guaranteed.

[0023] In addition, the housing is provided with a receiving groove for placing a magnetic metal plate. The magnetic metal plate is installed in the receiving groove by means of a first end being detachably connected to and positioned by the receiving groove, and the second end being fixed to the receiving groove by fasteners. This facilitates the installation of the magnetic metal plate on the housing and ensures the stability of the installation. During installation, the first end of the magnetic metal plate is first detachably connected to and positioned by the receiving groove, and then the second end is fixed in the receiving groove by fasteners. It can be seen that the installation operation is convenient. Attached Figure Description

[0033] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0034] In the description of this utility model, it should be understood that the terms "center," "longitudinal," "transverse," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," and "circumferential," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Since the embodiments disclosed in this utility model can be arranged in different directions, these terms indicating direction are only for illustration and should not be regarded as limitations. For example, "upper" and "lower" are not necessarily limited to directions opposite to or consistent with the direction of gravity. In addition, features defined with "first" and "second" may explicitly or implicitly include one or more of such features.

[0035] like Figures 1-9 As shown, a water purifier includes a housing 2 and a strip-shaped magnetic metal plate 1. One side surface of the magnetic metal plate 1 has a magnetic attraction surface 100 for magnetic attraction with a magnet on a door. The housing 2 has a receiving groove 3 for mounting the magnetic metal plate 1 behind its surface panel 21. The magnetic metal plate 1 is mounted in the receiving groove 3 by means of a first end being detachably connected to and positioned by the receiving groove 3, and a second end being fixed to the receiving groove 3 by fasteners 4. When the magnetic metal plate 1 is mounted in the receiving groove 3, its magnetic attraction surface 100 extends vertically in the left-right direction.

[0036] As can be seen from the above, this utility model utilizes the magnetism of the magnetic metal plate 1 itself to form a non-contact magnetic attraction with the magnet of the door, thereby achieving magnetic positioning of the door. Compared with magnets, the magnetic metal plate 1 has a uniform magnetic distribution and does not require distinguishing between N / S poles. Therefore, by replacing traditional magnets with the magnetic metal plate 1, there is no need to precisely match the magnetic poles during installation, reducing installation difficulty and the probability of errors, and lowering the production cost of the water purifier.

[0037] Furthermore, a magnetic attraction surface 100 is provided on one side surface of the magnetic metal plate 1 to ensure that the magnetic metal plate 1 can form a strong magnetic attraction with the magnet, thus ensuring the reliability of the closing action. Moreover, by extending the magnetic attraction surface 100 vertically in the left and right directions, a reliable magnetic attraction can be better ensured between the magnetic attraction surface 100 and the magnet of the door.

[0038] Furthermore, the housing 2 is provided with a receiving groove 3 for accommodating the magnetic metal plate 1. The magnetic metal plate 1 is installed in the receiving groove 3 by means of a first end being detachably connected to and positioned by the receiving groove 3, and the second end being fixed to the receiving groove 3 by a fastener 4 (in this embodiment, the fastener is specifically a screw). This facilitates the installation of the magnetic metal plate 1 on the housing 2 and ensures the stability of the installation. Moreover, during installation, the first end of the magnetic metal plate 1 is first detachably connected to and positioned by the receiving groove 3, and then the second end is fixed in the receiving groove 3 by the fastener 4, demonstrating convenient installation operation. In this embodiment, the magnetic metal plate 1 is specifically made of a galvanized sheet with magnetic properties.

[0039] Furthermore, such as Figure 3 and Figure 4 As shown, in this embodiment, preferably, the magnetic metal plate 1 is bent into a U-shape along its length and includes a magnetic suction wall 10 and a first connecting wall 11 and a second connecting wall 12 respectively connected to both ends of the magnetic suction wall 10. The outer surface of the magnetic suction wall 10 forms the magnetic suction surface 100, the first connecting wall 11 is embedded in the receiving groove 3, and the free end of the second connecting wall 12 has a mounting hole 13 and is fixed to the receiving groove 3 by the fastener 4.

[0040] By designing the magnetic metal plate 1 as a U-shape, the internal structural strength of the magnetic metal plate 1 is enhanced. In addition, it can better form the magnetic attraction surface 100, ensuring a stable magnetic attraction between the magnetic attraction surface 100 and the magnet of the door body. Furthermore, it can better achieve the detachable connection and positioning of the first end with the receiving groove 3, while the second end is fixed to the receiving groove 3 by the fastener 4, which helps to ensure the stable installation of the magnetic metal plate 1 in the receiving groove 3.

[0041] Furthermore, preferably, the length of the first connecting wall 11 is shorter than that of the second connecting wall 12. Since the second connecting wall 12 is fixed to the receiving groove 3 and the first connecting wall 11 is embedded in the receiving groove 3, designing the length of the first connecting wall 11 to be shorter than that of the second connecting wall 12 is beneficial to improving the stability of the installation structure between the magnetic metal plate 1 and the receiving groove 3.

[0042] Furthermore, the aforementioned housing 2 includes a frame 22 with an open front. The aforementioned faceplate 21 is fixed to the front edge 221 of the frame 22, with the front and back facing each other. The receiving groove 3 has a first insertion interface 31 and a second insertion interface 32 that pass through the front and back respectively on one side of the groove wall. Each insertion interface is an elongated hole, and its size matches the cross-sectional size of the aforementioned magnetic metal plate 1. During installation, the first end of the aforementioned magnetic metal plate 1 passes through each insertion interface in sequence until the bends at both ends of the magnetic wall 10 are located in the corresponding insertion interfaces, and the magnetic wall 10 extends out of the receiving groove 3 and is exposed on the front of the frame 22. By opening the first insertion interface 31 and the second insertion interface 32, the first end of the magnetic metal plate 1 is stably inserted into the receiving groove 3. Furthermore, the insertion allows the magnetic wall 10 to extend out of the mounting groove receiving groove 3 and be exposed on the front of the frame 22. This not only allows the magnetic surface 100 to be set in the desired position (extending vertically in the left and right direction) but also allows the exposed magnetic surface 100 to better form a non-contact magnetic adsorption with the magnet of the door.

[0043] Furthermore, an installation channel 330 is provided on the other side wall of the aforementioned receiving groove 3 along the depth direction of the receiving groove 3. When the aforementioned magnetic metal plate 1 is installed in the receiving groove 3, the aforementioned first connecting wall 11 is limited to the bottom of the receiving groove 3, while the aforementioned second connecting wall 12 is located in the opening of the receiving groove 3 and covers most of the opening, and the installation hole 13 is directly opposite to the installation channel 330. By limiting the first connecting wall 11 to the bottom of the receiving groove 3, the first connecting wall 11 is embedded in the receiving groove 3. By providing the installation channel 330 and making the installation hole 13 on the second connecting wall 12 directly opposite the installation channel 330, it is convenient to fix the second connecting wall 12 to the installation groove using fasteners 4. The fact that the second connecting wall 12 is located in the opening of the receiving groove 3 and covers most of the opening allows the magnetic metal plate 1 to be better accommodated in the receiving groove 3.

[0044] In this embodiment, specifically, as follows: Figure 3 and Figure 4 As shown, a mounting post 33 protrudes from the outer surface of the frame 22. The mounting post 33 extends along the depth direction of the receiving groove 3 and has the mounting channel 330. The mounting post 33, together with the mounting wall 23 protruding from the outer surface of the frame 22 or the wall at the corresponding location of the frame 22, forms the receiving groove 3 (e.g., Figure 1 and Figure 2As shown), with one side of the mounting post 33 located in the receiving groove 3, and the magnetic metal plate 1 installed in the receiving groove 3, the free end of the first connecting wall 11 abuts against the mounting post 33 and is thus limited. This allows for a better formation of the receiving groove 3 on the frame 22, and also allows for a better placement of the mounting hole 330 in the receiving groove 3. Furthermore, the first connecting wall 11 is limited at the bottom of the receiving groove 3 by abutting against the mounting post 33 with its free end.

[0045] Preferably, such as Figure 7 As shown, a groove 2211 matching the size of the magnetic wall 10 is formed by recessing the rim 221 on the front of the frame 22 at the corresponding location of the receiving groove 3. The first insertion interface 31 and the second insertion interface 32 are respectively located in the groove 2211. With the magnetic metal plate 1 installed in the receiving groove 3, the magnetic wall 10 is accommodated in the groove 2211, and the magnetic surface 100 of the magnetic wall 10 is flush with the rim 221. This prevents the magnetic wall 10 from protruding from the rim 221 on the front of the frame 22, facilitating the assembly of the frame 22 and the faceplate 21, and also facilitating the magnetic attraction between the magnetic surface 100 and the magnet of the door.

[0046] Preferably, the magnetic attraction surface 100 is a square or a rectangle with similar length and width (e.g., ...). Figure 7 (As shown). During installation, the magnetic metal plate 1 can be placed horizontally or vertically depending on the different opening directions of the receiving slot 3. This allows for flexible installation of the receiving slot 3 on the housing 2 according to space requirements. Specifically, in this embodiment, as shown... Figures 1-4 As shown, there are two magnetic metal plates 1, respectively disposed at the upper and lower ends of one side of the housing 2. There are two receiving slots 3, each corresponding to one of the magnetic metal plates 1. The magnetic metal plate 1 located at the upper end of the housing 2 is horizontally arranged vertically, with the first connecting wall 11 located below the second connecting wall 12. The receiving slot 3 corresponding to this magnetic metal plate 1 extends vertically and opens upwards. The magnetic metal plate 1 located at the lower end of the housing 2 is horizontally arranged horizontally, with the first connecting wall 11 located inside the second connecting wall 12 relative to the housing 2. The receiving slot 3 corresponding to this magnetic metal plate 1 extends horizontally and opens outwards relative to the housing 2. This arrangement of two magnetic metal plates 1, with each plate attracting a corresponding magnet on the door, helps ensure the door closes securely and prevents accidental opening.
