Description

Technical Field

[0001] The utility model relates to the technical field of water purifiers, and more specifically, to an embedded water purifier with a safety protection structure. Background Art

[0002] The water purifier integrates water purification and drinking. According to different household use area scenarios, it has developed into various structural installation forms such as under-counter type, countertop type, wall-mounted type, and embedded type. For example, the embedded water purifier is mainly installed in the kitchen cabinet or the wall. The installation space environment in the cabinet or the wall is very limited. And to ensure the aesthetics after installation, there is no large reserved gap between the water purifier body and the cabinet wall surface. The water connection of the water purifier is generally hidden at the back of the water purifier and is not convenient to directly observe. This further leads to very limited activity space and observation line of sight during the installation of the water purifier.

[0003] The embedded water purifier is generally directly connected to the external water source outside the kitchen for filtration. After the water purifier is placed in a suitable position in the cabinet or the wall, the external water pipe needs to be connected to the rear water inlet of the water purifier to achieve water connection. The narrow operation space affects both the convenience and safety of the water connection. Especially during the process of inserting the water purifier into the cabinet or the wall, and during the pipeline connection process, if there is accidental impact or collision, it is very likely to cause damage to the connection water inlet or affect the accuracy of the installation position, thus affecting the sealing of the pipeline connection and resulting in subsequent water leakage. And the embedded water purifier is basically hidden inside the cabinet or the wall, making it difficult to detect the water leakage situation in time, which is likely to cause greater damage to the water purifier, the cabinet wall, etc. Therefore, it is very necessary to improve the convenience and safety of the pipeline connection of the embedded water purifier.

[0004] For example, the patent with the publication number CN218901081U provides an anti-collision structure for a water purifier. There are water inlets and outlets and slots on the shell. There are bolts on the water inlets and outlets, and an anti-impact part is detachably arranged on the slots. The height of the anti-impact part on the shell is higher than the height of the bolt on the shell. This design can prevent the bolt from colliding with the wall or the back panel of the cabinet when the user installs the water purifier or replaces the filter element of the water purifier, resulting in the breakage of the bolt or the water inlets and outlets of the water circuit board, and has a certain safety protection effect. However, there is still room for further optimization in practical applications, especially in how to further improve the convenience during pipeline connection, which is still worthy of exploration in the industry. Summary of the Utility Model

[0005] 1. Technical Problems to be Solved by the Utility Model

[0006] In view of the situation in the prior art that the installation space of the embedded water purifier is limited, and it is easy to damage the water outlet during the installation process, affecting the sealing performance of the pipeline connection, the present utility model intends to provide an embedded water purifier with a safety protection structure. By adopting such a protection structure, the convenience of the pipeline connection of the water outlet can be effectively improved, the water outlet can be prevented from being damaged, and the sealing performance of the pipeline connection and the long-term application safety can be guaranteed.

[0007] 2. Technical solution

[0008] To achieve the above object, the technical solution provided by the present utility model is as follows:

[0009] An embedded water purifier with a safety protection structure of the present utility model includes: a front panel and a water circuit board. The front panel is the front appearance panel of the water purifier, and there is a water receiving area at the front panel. During installation, the rear side wall and the surrounding side walls of the water purifier are all embedded in the accommodating space of the water purifier, and the extension in the up, down, left, and right directions does not exceed the peripheral edge range of the front panel. Thus, only the front panel is displayed after the water purifier is embedded in the cabinet or wall, which is compact and beautiful in distribution; the water circuit board is installed inside the water purifier, and at least one connection water outlet is provided on the water circuit board. The connection water outlet is used to connect an external pipeline; particularly, an inwardly recessed installation space is provided on the rear side of the water purifier facing away from the front panel. The connection water outlet on the water circuit board extends into this installation space. The installation space is used for connecting the connection water outlet with the external pipeline, and the area occupied by the installation space does not extend beyond the rear side wall of the water purifier backward and does not extend beyond the left and right side walls of the water purifier in the left and right directions, so that after the connection water outlet is connected with the external pipeline, it is hidden behind the front panel.

[0010] In this solution, an embedded installation space is provided on the rear side of the water purifier as the operation space for the connection water outlet and the external pipeline, making the pipeline connection more convenient. And this installation space does not exceed the rear wall of the water purifier backward, does not exceed the bottom wall of the water purifier downward, and does not exceed the left and right side walls of the water purifier in the left and right directions. The water circuit interface is completely located inside the installation space, which can effectively prevent collision, avoid directly hitting the water circuit interface during the process of moving the embedded water purifier, and ensure the position accuracy and connection sealing performance of the subsequent pipeline connection.

[0011] For further protection, first protection columns are also provided on both sides of the connection water outlet in the installation space. The length extension direction of the first protection columns is the same as the length extension direction of the connection water outlet; the extension length of the first protection columns in the installation space exceeds and covers the extension length of the connection water outlet in the installation space, and the first protection columns do not extend beyond the installation space area. The use of the first protection columns can enhance the protection effect on the connection water outlet. Even if there is an impact in the installation space area, it will first collide with the first protection columns, rather than directly hitting the connection water outlet.

[0012] As a preferred solution, a back panel is provided on the rear side of the water purifier away from the front panel, and a bottom panel is provided at the bottom of the water purifier. The back panel and the bottom panel are respectively the rear appearance panel and the bottom appearance panel of the water purifier. The bottom of the back panel has an inner extension panel facing the front side of the water purifier, and the rear end of the bottom panel has an upper extension panel facing upward. The front end of the inner extension panel is connected to the upper end of the upper extension panel, so as to form an installation space at the bottom of the rear side of the water purifier. In practice, as an embedded water purifier design, except for the front panel that needs to be displayed, the bottom panel, the back panel and the surrounding panels of the water purifier are hidden in the cabinet or wall. Therefore, there is no need to set up the appearance panel, and the corresponding installation space can be directly reserved at the rear side of the water purifier. As a preferred solution, appearance panels such as the back panel and the bottom panel can also be retained on all sides. In this case, the back panel and the bottom panel can be used to form an installation space at the bottom of the rear side of the water purifier. More preferably, the inner extension plate extends laterally toward the front side, and the upper extension plate extends vertically upward, so that the cross-section of the installation space is approximately rectangular, and the overall shape of the water purifier is relatively regular and beautiful. In practice, the lateral extension of the inner extension plate can be completely horizontally extended toward the front side, or preferably extended in an inclined manner with a slightly lower height toward the front side. If the waterway plate leaks, water can flow into the body of the water purifier along the inner extension plate with a lowered height tilted forward. A water leakage protection component will be correspondingly provided near the waterway plate in the water purifier, which can detect the presence of water leakage in a timely manner, thereby discovering the water leakage in a timely manner.

[0013] In this solution, the first protective column can be set on the inner extension plate and extend downward beyond the connecting water outlet. In practice, the upper extension plate and the inner extension plate can be formed integrally with the bottom plate, that is, two bending processes are performed on the rear end of the bottom plate to make the rear end of the bottom plate present an approximately L-shaped bending portion, and then the rear end of the inner extension plate is connected to the bottom of the back plate accordingly. Other processing and forming methods can also be used to form an inwardly concave installation space between the back plate and the bottom plate.

[0014] Preferably, the waterway plate is arranged inside the water purifier near the back plate, and the connecting water outlet is located at the bottom of the height direction of the waterway plate and extends downward; a corresponding installation opening for the connecting water outlet to pass through is arranged on the inner extension plate, and the connecting water outlet extends downward through the installation opening, and the distance that the connecting water outlet extends beyond the installation opening is less than the height distance of the installation space. In order to achieve the coordinated installation of the waterway plate, this scheme preferably extends the thickness direction of the waterway plate along the front-to-back direction of the water purifier, so that the waterway plate is longitudinally distributed above the inner extension plate, and the side of the waterway plate away from the back plate is the installation surface for installing the filter element, that is, the front of the waterway plate, and the back of the waterway plate is the side close to the back plate. No connection interface may be arranged on the back of the waterway plate, so that it is as close to the back plate as possible, the installation is more compact, and space is saved. It can also make the connecting water outlet of the waterway plate as far back as possible and extend out of the machine body, so as to facilitate the rear connection.

[0015] In practice, it is further preferably that first protective columns are respectively provided on both sides of the bottom of the inner extension plate in the left-right length direction, and the connection water inlets at the bottom of the water circuit plate are located between the first protective columns on both sides. The connection water inlets are surrounded by the first protective columns on both sides, so as to achieve comprehensive protection and avoid accidental collision on either side. Further, a plurality of connection water inlets are successively arranged on the bottom of the water circuit plate along the left-right length direction, and a plurality of installation openings are correspondingly arranged on the inner extension plate in sequence; all the plurality of connection water inlets are located between the first protective columns on both sides. The arrangement of the plurality of connection water inlets can be correspondingly set according to the functions of the water purifier to meet the user's usage requirements. Concentrating the plurality of connection water inlets between the first protective columns on both sides not only makes the structure more compact and concise, but also facilitates comprehensive protection. Preferably, the plurality of installation openings on the inner extension plate are centrally distributed in the left-right length direction, and the first protective columns on both sides are symmetrically distributed outside the plurality of installation openings, making the layout more compact and beautiful.

[0016] In addition to the bottom anti-collision protection, further, a second protective column is also provided on the rear side wall surface of the water purifier facing away from the front panel. The second protective column extends towards the rear side direction of the water purifier, and the area where the second protective column extends beyond the installation space in the front-rear direction. When there is no appearance panel provided on the rear side of the water purifier, the second protective column can be provided on a certain installation frame or a certain functional component facing the rear side of the water purifier, etc., as long as the second protective column can extend towards the rear side direction of the water purifier. When a back panel is provided as the appearance panel on the rear side of the water purifier, preferably, second protective columns are respectively provided at both ends of the bottom of the back panel in the left-right length direction. The second protective column extends backward by a certain length, which can effectively prevent the back panel from directly hitting and contacting the cabinet or the wall when moving or installing the water purifier. Instead, the second protective column first contacts the cabinet or the wall to indicate that the installation has reached the limit position. The second protective column not only avoids the impact on the back panel, but also enables a certain gap space to be reserved between the back panel and the cabinet or the wall, which is more convenient for the connection and installation of pipelines and further avoids impact damage to the position of the connection water inlet.

[0017] In addition, a heat dissipation channel penetrating through the front-rear thickness direction is provided on the back panel in this solution. A heat dissipation fan is correspondingly provided inside the water purifier on the inner side of the heat dissipation channel. The heat dissipation fan is preferably located on one side above the water circuit plate. The heat dissipation channel is located on one side of the upper part of the back panel. The second protective column can not only achieve effective anti-collision protection, but also form an effective gap with the wall and the cabinet, cooperate with the heat dissipation channel, form a more sufficient heat dissipation space, promote the efficient heat dissipation of the heat dissipation risk, and ensure the long-term use of the water purifier.

[0030] To further understand the content of the present utility model, the present utility model will be described in detail in conjunction with the accompanying drawings

[0031] In the description of the present utility model, it should be noted that the orientation or positional relationship indicated by the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation to the present utility model. In addition, the terms "first", "second", "third" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance

[0032] The following further describes the present utility model in conjunction with the embodiments

[0033] Embodiment

[0034] In combination with Figures 1 - 6As shown, an embedded water purifier with a safety protection structure of the present embodiment includes: a front panel 130 and a waterway plate 200, the front panel 130 is the front appearance panel of the water purifier facing the user, and the front panel 130 has a water receiving area, the rear wall and the surrounding walls of the water purifier are embedded in the wall or cabinet, and the extension does not exceed the surrounding edge range of the front panel 130, so that after being embedded in the cabinet or wall, only the front panel 130 is displayed, the visual effect is beautiful and concise, and the wall or cabinet forms a unified whole; the waterway plate 200 is installed inside the water purifier, and at least one connecting water outlet 201 is provided on the waterway plate 200, and the connecting water outlet 201 is used to connect an external pipeline.

[0035] In practice, the sealing of the pipe connection of the embedded water purifier is particularly important. If there is a leak in the pipe, not only is it difficult to find it in time due to obstructed vision, but it is also more likely to corrode the surrounding cabinets or walls, and even mold in the long run. In conventional home design, there are often multiple layers of embedded space on the wall or cabinet to place multiple embedded household appliances in layers, such as placing a water purifier on the upper layer and a microwave oven on the lower layer. If the water purifier leaks, the water will flow into the lower layer of appliances and may even damage other appliances, causing greater losses. Therefore, it is particularly important to protect the pipe installation of the embedded water purifier.

[0036] In this embodiment, the rear side of the water purifier away from the front panel 130 is provided with an inwardly recessed installation space 112, and the connecting water port 201 on the waterway plate 200 extends into the installation space 112. The installation space 112 is used for connecting the connecting water port 201 with an external pipeline, and the area occupied by the installation space 112 does not exceed the rear wall surface of the water purifier in the rear direction, and does not exceed the left and right side walls of the water purifier in the left and right directions, so that the connecting water port 201 is hidden in the rear area of ​​the front panel 130 after being connected to the external pipeline. Using the installation space 112 as a pipeline connection space facilitates the pipe connection operation, and the connecting water port 201 can be enclosed inside the installation space 112, which helps to prevent foreign objects from directly colliding with the connecting water port 201, and ensures the position accuracy and connection sealing of the subsequent connection of the connecting water port 201.

[0037] In order to further improve the protection performance, first protective columns 121 are respectively provided on both sides of the connecting water outlet 201 in the installation space 112. The length extension direction of the first protective column 121 is consistent with the length extension direction of the connecting water outlet 201. The extension length of the first protective column 121 in the installation space 112 exceeds and covers the extension length of the connecting water outlet 201 in the installation space 112, and the first protective column 121 does not extend beyond the area of ​​the installation space 112. The connecting water outlet 201 is further surrounded on the inside by the first protective column 121, and the first protective column 121 is consistent with the extension direction of the connecting water outlet 201 and completely covers the extension length of the connecting water outlet 201. Even if an accidental collision occurs in the area where the installation space 112 is located, the first protective column 121 will be collided with first protective column 121 first, and the connecting water outlet 201 will not be directly collided. Thus, enhanced protection of the connecting water outlet 201 can be formed, damage to the connecting water outlet 201 can be avoided, and the accuracy and sealing of subsequent pipeline connection can be guaranteed.

[0038] Since the embedded water purifier is completely embedded in the cabinet or wall during installation, except for the front panel 130 as the appearance panel, the appearance panel is not required in other directions. In practice, it is also possible to choose to set appearance panels on each wall surface, which makes the shape more regular and beautiful, and further protects the internal devices, and is convenient for overall transportation and movement. As a specific design of the installation space 112, the rear side of the water purifier away from the front panel 130 is provided with a back panel 100, and the bottom of the water purifier has a bottom plate 110. The back panel 100 and the bottom plate 110 are the rear and bottom appearance panels. The bottom of the back panel 100 is provided with an inner extension plate 101 facing the front side of the water purifier, and the rear end of the bottom plate 110 is provided with an upper extension plate 111 facing upward, and the front end of the inner extension plate 101 is connected to the upper end of the upper extension plate 111, thereby forming an installation space 112 at the rear bottom of the water purifier. Specifically, in practice, it can be selected that the inner extension plate 101 extends horizontally to the front side, specifically, it can extend horizontally forward or extend obliquely with a lowered height forward. When the oblique extension occurs, it is more convenient for the water flow to be directed toward the inner side of the water purifier when a water leak occurs, so that the water leakage protection component set in the water purifier can detect the water leak in time; and the upper extension plate 111 extends vertically upward, so that the cross section of the installation space 112 is approximately rectangular, forming a long strip installation space 112 extending along the left and right length direction of the water purifier and consistent with the length of the water purifier. Correspondingly, preferably, the waterway plate 200 is arranged inside the water purifier near the back plate 100, and the connecting water port 201 is located at the bottom of the height direction of the waterway plate 200 and extends downward; the inner extension plate 101 is correspondingly provided with a mounting port 102 for the connecting water port 201 to pass through, and the connecting water port 201 extends downward through the mounting port 102, and the height of the connecting water port 201 extending beyond the mounting port 102 is less than the height of the mounting space 112. The first protection column 121 is correspondingly disposed at the bottom of the inner extension plate 101 and extends vertically downward.

[0039] In this embodiment, the water circuit board 200 is attached close to the back board 100, and the connection water inlet 201 is arranged to extend downward from the bottom of the water circuit board 200. After passing through the installation opening 102, the connection water inlet 201 extends toward the installation space 112. The installation space 112 is formed at the bottom as an installation operation space for the connection water inlet 201 and an external pipeline, facilitating the connection of the pipeline from the bottom. Utilizing this installation space 112 also helps to protect the connection water inlet 201. The downward extension distance of the connection water inlet 201 is less than the height of the installation space 112, so that the connection water inlet 201 is located inside the installation space 112. The back board 100 is at the rearmost side, and the bottom board 110 is at the bottommost side, which helps to reduce the accidental collision of the connection water inlet 201 when installing or inserting the water purifier, avoiding damage to the connection water inlet 201 and affecting its subsequent sealing performance.

[0040] More preferably, in practice, a plurality of connection water inlets 201 can be sequentially arranged along the left - right length direction at the bottom of the water circuit board 200, and a plurality of installation openings 102 are correspondingly arranged in sequence on the inner extension board 101; first protection columns 121 are respectively arranged on both sides of the bottom of the inner extension board 101 along the left - right length direction, and a plurality of connection water inlets 201 are all located between the first protection columns 121 on both sides. In this embodiment, for example, four connection water inlets 201 are sequentially arranged along the left - right length direction at the bottom of the water circuit board 200, which are respectively a water inlet, a wastewater outlet, a primary filtration water inlet, and a purified water outlet. The water inlet is connected to the raw water inlet pipeline and is used to introduce raw water into the water purifier for filtration; the wastewater outlet is connected to the waste discharge pipeline and is used to discharge the wastewater generated by filtration; the primary filtration water inlet is used to connect the pre - filtered pure water in the water purifier to the kitchen domestic water pipeline to meet the large - flow domestic water demand; the purified water outlet is connected to the drinking water pipeline to meet the drinking water quality requirement. Correspondingly, in this embodiment, four installation openings 102 are arranged along the length direction on the inner extension board 101, and the four connection water inlets 201 are surrounded inside by the first protection columns 121 on both sides of the inner extension board 101.

[0041] In this embodiment, it is preferred that the thickness direction of the water circuit board 200 extends along the front - rear direction of the water purifier, combined with Figure 4As shown, the waterway board 200 is longitudinally distributed above the inner extension board 101, and the side of the waterway board 200 facing away from the back panel 100 is the installation surface for installing the filter element, that is, the front of the waterway board 200. Preferably, no component interfaces are provided on the back of the waterway board 200, which facilitates the waterway board 200 to be arranged as close to the back panel 100 as possible to save installation space and also makes the position of the connection water inlet 201 as far back as possible to facilitate the connection of the rear pipeline. Further, the length direction of the waterway board 200 is arranged along the left-right length direction of the water dispenser, and the width direction of the waterway board 200 is arranged along the height direction of the water dispenser. Preferably, the thickness direction of the waterway board 200 does not exceed the front-back extension width of the inner extension board 101, so as to form an independent installation area for the waterway board 200 above the inner extension board 101, which is convenient for the compact installation of the waterway board 200.

[0042] To further improve the safety protection of the built-in water dispenser, a second protection post 120 is also provided on the rear side wall surface of the water dispenser facing away from the front panel 130. The second protection post 120 extends towards the rear side of the water dispenser, and the second protection post 120 extends beyond the area of the installation space 112 in the front-back direction. In practice, it is preferable that the second protection post 120 is arranged at the bottom of the back panel 100, and the second protection post 120 extends from the back panel 100 towards the rear side of the water dispenser. And preferably, the second protection post 120 is provided at both ends of the bottom of the back panel 100 in the left-right length direction. As Figure 5 shown, optionally, the multiple installation openings 102 on the inner extension board 101 are centrally distributed in the left-right length direction, the first protection posts 121 on both sides are symmetrically distributed outside the multiple installation openings 102, and the second protection posts 120 on both sides are located outside the first protection posts 121 in the left-right length direction. The second protection post 120 extends backward for a certain length along the length direction of the water dispenser, thus forming an anti-collision limit structure. When installing the water dispenser, especially when the water dispenser is inserted into the cabinet or wall from front to back, the second protection post 120 can effectively prevent the wall or cabinet from directly colliding with the back panel 100. Instead, when contacting the second protection post 120, it reminds the installer that the position has reached the limit. The setting of the second protection post 120 can also provide more sufficient space behind the back panel 100, and there is more sufficient installation operation space when the connection water inlet 201 at the bottom of the waterway board 200 is connected to the pipeline. Moreover, the connecting pipeline is located in the installation space 112, and through the limit of the second protection post 120, a certain gap can also be maintained with the rear cabinet or wall, further avoiding the situation of collision damage and ensuring long-term safe use.

[0043] In this embodiment, preferably, a heat dissipation channel 103 penetrating the front-back thickness direction of the rear back plate 100 is provided. Specifically, a heat dissipation fan is provided inside the water purifier to dissipate heat from the inside of the machine body. The heat dissipation fan can be arranged above the water circuit board 200 and close to the rear back plate 100. Correspondingly, a heat dissipation channel 103 communicating with the outside is provided at the position of the upper part of the rear back plate 100 corresponding to the heat dissipation fan to achieve ventilation and heat dissipation at the rear side of the water purifier. By setting the second protection column 120, not only can the effective limit and safety anti-collision of the water purifier be realized, but also an effective gap can be formed between the installation wall or cabinet, which cooperates with the heat dissipation channel 103 to form a more favorable heat dissipation space, promoting the efficient heat dissipation and stable operation of the water purifier.

[0044] In this embodiment, by forming an installation space 112 at the bottom of the rear side of the built-in water purifier and cooperating with the settings of the first protection column 121 and the second protection column 120, effective protection can be provided for the rear back plate 100 of the water purifier housing itself and the connection between the bottom connection water inlet 201 of the water circuit board 200 and the external pipeline, avoiding impact damage to the housing and the pipeline connection position, and not affecting the front and overall appearance of the built-in water purifier at all, which can meet the multiple requirements of users for the use performance and appearance of the built-in water purifier.

[0045] The above schematically describes the present invention and its implementation manners. This description is not restrictive, but only one of the implementation manners of the present invention, and the actual situation is not limited thereto. Therefore, if those of ordinary skill in the art are inspired by it and design similar structural manners and embodiments without creative work without departing from the creative purpose of the present invention, they shall fall within the protection scope of the present invention.
