Description

TECHNICAL FIELD

[0001] The utility model relates to water treatment technical field, specifically, relate to a kind of embedded water purifier. BACKGROUND

[0002] With the development of the times, people's requirements for drinking water quality are higher and higher, and water purifiers have been recognized and purchased by most people. Water purifiers can purify tap water or water in water tanks to provide high-quality purified water to users. The water purifiers on the market can include desktop water purifiers, under-kitchen water purifiers and embedded water purifiers, etc. The embedded water purifier can be embedded in a cabinet, a side cabinet, etc. Since it does not occupy the space on the table, it has also become the choice of many people.

[0003] The embedded water purifier can be provided with a water taking nozzle and a bearing table protruding from its surface, so that the user can place a water taking container and take water. Some embedded water purifiers on the market are provided with a water taking cavity, and the user can place the water taking container on the bottom surface of the water taking cavity to take water. The size of the water taking cavity will greatly affect the user's experience.

[0004] The size of the accommodation space is usually determined, so that the size of the embedded water purifier is also limited. With more and more functions of the embedded water purifier, the space arrangement of the embedded water purifier is also more tense. For the embedded water purifier provided with a water taking cavity, how to reasonably arrange the component arrangement of the embedded water purifier while ensuring the size of the water taking cavity has become a problem that needs to be solved. SUMMARY

[0005] To at least partially address the problems existing in the prior art, some embodiments of this utility model provide an embedded water purifier, comprising: a housing assembly forming an inner cavity, a first wall of the housing assembly recessed into the inner cavity to form a water intake cavity, the width of the water intake cavity increasing along the direction away from the inner cavity; a water outlet located at the top of the water intake cavity; and a first filter element assembly and a second filter element assembly, both disposed within the inner cavity, and located on opposite sides of the water intake cavity, wherein: the lateral width of the portion of the water intake cavity away from the inner cavity is greater than the lateral width of the gap between the first and second filter element assemblies; and the portion of the water intake cavity near the inner cavity is narrower than the gap, such that the portion of the water intake cavity near the inner cavity is located within the gap. This allows for a reasonable layout even when the front-to-back dimensions of the embedded water purifier are limited and it contains many internal components. On the one hand, it ensures that the water intake cavity has a sufficiently large opening, facilitating the placement of various types of water containers, such as kettles, pots, and basins, in addition to water cups. On the other hand, the portion of the water intake chamber near the inner cavity is located within a gap, allowing for sufficient depth. This prevents the water container placed within the chamber from easily falling out during water collection. Therefore, by rationally arranging the positional relationship between the first filter assembly, the second filter assembly, and the water intake chamber, as well as the shape of the water intake chamber, the dimensions of the water intake chamber are ensured.

[0006] For example, the water intake cavity includes: a top wall and a bottom wall, which are vertically opposite to each other; a second wall, a first side wall, and a second side wall, all connected between the top wall and the bottom wall. In the lateral direction, the first side wall and the second side wall are located on opposite sides of the second wall, wherein the lateral direction includes opposing first and second lateral directions. The second wall is located within the gap, the first side wall extends obliquely across the first filter element assembly in the first lateral direction, and the second side wall extends obliquely across the second filter element assembly in the second lateral direction, facing away from the inner cavity. Thus, the cross-section of the water intake cavity is funnel-shaped. This is not only more aesthetically pleasing but also avoids sharp corners in areas prone to contamination, reducing hard-to-clean corners. Furthermore, the inner surface of the water intake cavity can be smoothly transitioned, allowing for low-cost processing using techniques such as sheet metal work.

[0007] For example, the distance between the front edges of the first and second sidewalls is greater than the center distance between the first and second filter element assemblies. This allows the water intake chamber to have a sufficiently large size to accommodate a large water intake container, such as a pot or basin.

[0008] For example, the water intake cavity further includes a third sidewall and a fourth sidewall both connected between the top wall and the bottom wall, wherein: the first sidewall is connected between the third sidewall and the second wall, and the second sidewall is connected between the fourth sidewall and the second wall, with the third and fourth sidewalls arranged opposite to each other in the lateral direction. This ensures that the opening of the first wall exposing the water intake cavity is not too large. The above structure avoids excessively large bends at the bends and prevents the edge of the water intake cavity opening from being too close to the edge of the first wall of the embedded water purifier, thereby ensuring the strength of the first wall and the water intake cavity.

[0009] For example, along the arrangement direction of the first and second walls, the dimensions of the third and fourth side walls are each less than half the dimension of either the first or second side wall. This not only makes the built-in water purifier more aesthetically pleasing but also allows the opening of the water intake chamber to have a larger lateral dimension.

[0010] For example, along the arrangement direction of the first and second walls, at least one of the third and fourth side walls is provided with a vent. This arrangement of the vent is more concealed, making the appearance of the embedded water purifier more streamlined. For the vent that blows air outwards, placing it on the third and / or fourth side walls can guide the airflow, preventing it from affecting the user experience.

[0011] For example, each of the first and second filter cartridge assemblies includes a filter cartridge and a filter base, with the filter base mounted at the bottom of the inner cavity and the filter cartridge vertically and detachably mounted to the filter base. This allows users to easily replace the filter cartridge without requiring complex water circuit connections.

[0012] For example, the filter holder includes a locking mechanism that locks the filter element in place when it is installed. The horizontal cross-sectional area of ​​the filter element is smaller than that of the filter holder, and the filter element's horizontal projection completely falls within the horizontal projection of the filter holder. At least a portion of the filter holder facing the water intake cavity projects in a fan shape on the horizontal plane, and the minimum distance between the filter holder and the water intake cavity is less than a preset threshold. This makes installation simpler and more reliable. When designing the relationship between the filter element assembly and the water intake cavity, a filter holder with a larger cross-sectional area can be used as a reference. The portion enclosed by the front and side surfaces of the filter holder can be constructed to be fan-shaped on the horizontal plane, thus providing sufficient space to accommodate the aforementioned buttons. Furthermore, the filter holder can avoid interference with the water intake cavity, thereby meeting the design requirements of an embedded water purifier.

[0013] For example, the housing assembly includes: a rear housing with replacement openings for a first filter assembly and a second filter assembly; and a front door, which is closable and connectable to the rear housing. The front door and the rear housing together form an inner cavity, and a water intake cavity is formed on the front door. Therefore, the user does not need to remove or pull the built-in water purifier from its housing, reducing workload and decreasing the possibility of the built-in water purifier tipping over due to instability when pulled out of its housing.

[0014] For example, the front door is pivotally connected to the rear shell between an open and closed position about a pivot axis extending vertically. Lateral opening typically does not obstruct user operation and requires no additional retaining structure, offering both cost-effectiveness and convenience.

[0015] For example, the rear housing is provided with a first partition and a second partition. The first partition divides the inner cavity into a first filter cartridge compartment for accommodating a first filter cartridge assembly, and the second partition divides the inner cavity into a second filter cartridge compartment for accommodating a second filter cartridge assembly. The front sides of both the first and second filter cartridge compartments are open and communicate with the filter cartridge replacement opening. There is a single front door, which, when closed, simultaneously covers the front sides of both the first and second filter cartridge compartments. The first and second filter cartridge compartments can isolate the first and second filter cartridge assemblies from other components in the inner cavity. The first and second partitions extend from the bottom to the top of the inner cavity, effectively preventing water from flowing into the electrical component area. This allows the outer side panel of the front door to be a single piece, without gaps, resulting in a more aesthetically pleasing appearance and easier cleaning.

This utility model description is not intended to limit the key features and essential technical features of the claimed technical solution, nor is it intended to determine the scope of protection of the claimed technical solution.

[0027] In the following description, numerous details are provided to enable a thorough understanding of the present invention. However, those skilled in the art will appreciate that the following description merely illustrates preferred embodiments of the present invention, which may be practiced without one or more of these details. Furthermore, to avoid confusion with the present invention, some technical features well-known in the art have not been described in detail.

[0028] To fully understand the embodiments of this utility model, a detailed structure will be presented in the following description. Obviously, the implementation of the embodiments of this utility model is not limited to the specific details familiar to those skilled in the art. Preferred embodiments of this utility model are described in detail below; however, in addition to these detailed descriptions, this utility model may have other embodiments.

[0029] This utility model provides an embedded water purifier. The embedded water purifier according to an embodiment of this utility model will be described in detail below with reference to the accompanying drawings.Figure 1 As shown, the embedded water purifier includes a housing assembly 100. The housing assembly 100 encloses to form an inner cavity 103. In some embodiments, the housing assembly 100 may be made of metal and manufactured using processes such as sheet metal fabrication. In other embodiments, the housing assembly 100 may also be made of materials such as plastic and manufactured using injection molding. The inner cavity 103 can be considered as the space that houses all the internal components of the embedded water purifier. In some embodiments, the inner cavity 103 may have multiple non-communicating areas to separate water channels, electrical circuits, and internal airflow.

[0030] The first wall 101 of the housing assembly 100 can be recessed into the inner cavity 103 to form a water intake cavity 210. In some embodiments, the user can place a water container on the bottom surface of the water intake cavity 210, thus eliminating the need to constantly support the water container during water intake. The water intake cavity 210, formed by the recess into the inner cavity 103, ensures that the embedded water dispenser has no structure protruding from the front surface. This prevents the user from bumping into protruding parts and injuring or damaging the embedded water dispenser during use. The width of the water intake cavity 210 increases in the direction away from the inner cavity.

[0031] An embedded water purifier may include a water dispensing nozzle 300, which provides the user with the required water during dispensing. The water dispensing nozzle 300 may be located at the top of the water dispensing chamber 210. As shown in the figure, the water dispensing nozzle 300 may be positioned in the middle of the water dispensing chamber 210. Specifically, in the lateral direction, the water dispensing nozzle 300 is positioned near the center line; in the front-back direction, i.e., the depth direction of the water dispensing chamber 210, the center line of the water dispensing nozzle 300 is also close to or coincides with the center line of the water dispensing chamber 210. This provides a sufficiently large area directly below the water dispensing nozzle 300, preventing the water container from falling when placed by the user.

[0032] The embedded water purifier may further include a first filter assembly 510 and a second filter assembly 520, both of which are disposed within the inner cavity 103, and are located on opposite sides of the water intake cavity 210. Each of the first filter assembly 510 and the second filter assembly 520 may include a removable filter element and a filter element holder. For the filter elements, the first filter assembly 510 and the second filter assembly 520 may each include a pre-filter and a central filter, or each may include a central filter and a post-filter. The central filter plays the primary filtration role. Taking the first filter assembly 510 and the second filter assembly 520 as a pre-filter and a central filter respectively, the pre-filter may be a composite filter element located before the central filter element, used for initial filtration of the water entering the central filter element to extend its service life. The central filter element may include a reverse osmosis filter element, an ultrafiltration filter element, a nanofiltration filter element, or a filter element composed of any two or more of these. For reverse osmosis and nanofiltration filters, the water needs to be pressurized before entering the filter. In this case, the built-in water purifier may also include a booster pump. This provides users with high-quality purified water. Specifically, the lateral width of the portion of the water intake chamber 210 away from the inner cavity 103 is greater than the lateral width of the gap between the first filter assembly 510 and the second filter assembly 520, and the portion of the water intake chamber 210 near the inner cavity 103 is narrower than the gap, such that the portion of the water intake chamber 210 near the inner cavity 103 is located within the gap. In some embodiments, the inner wall of the water intake chamber 210 may be straight, making the horizontal cross-section of the water intake chamber 210 generally trapezoidal. In other embodiments, the wall of the water intake chamber 210 may have curves or bends; for example, the horizontal cross-section of the water intake chamber 210 may be stepped. In summary, the wall of the water intake chamber 210 can provide clearance from the first filter assembly 510 and the second filter assembly 520.

[0033] Therefore, the layout can be rationally arranged even with limited front and rear dimensions and numerous internal components in the built-in water purifier. On one hand, it ensures that the water intake chamber 210 has a sufficiently large opening, facilitating the placement of various types of water containers, including cups, kettles, pots, and basins. On the other hand, the portion of the water intake chamber 210 near the inner cavity 103 is located within a gap, allowing for sufficient depth. This prevents water containers placed in the water intake chamber 210 from falling out during water dispensing. Thus, by rationally arranging the positional relationship between the first filter assembly 510, the second filter assembly 520, and the water intake chamber 210, as well as the shape of the water intake chamber 210, the dimensions of the water intake chamber 210 are ensured.

[0034] For example, the water intake cavity 210 includes a top wall 211 and a bottom wall, which are vertically opposite to each other. The water intake cavity 210 also includes a second wall 213, a first side wall 214, and a second side wall 215, all connected between the top wall 211 and the bottom wall. Laterally, the first side wall 214 and the second side wall 215 are located on opposite sides of the second wall 213. The lateral direction includes a first lateral direction and a second lateral direction. The second wall 213 is located within the gap. The first side wall 214 extends away from the inner cavity 103 and obliquely in the first lateral direction beyond the first filter element assembly 510, i.e., the first side wall extends to the front of the first filter element assembly 510 shown in the figure. The second side wall 215 extends away from the inner cavity 103 and obliquely in the second lateral direction beyond the second filter element assembly 520. Thus, the cross-section of the water intake cavity 210 is funnel-shaped. This design is not only more aesthetically pleasing, but also avoids sharp corners in areas prone to contamination, thus reducing hard-to-clean areas. Furthermore, the inner surface of the water intake cavity 210 can be smoothly transitioned, allowing for low-cost processing using techniques such as sheet metal work.

[0035] As described above, the lateral dimensions of the built-in water purifier are limited by the available space, resulting in a small center-to-center distance between the first filter assembly 510 and the second filter assembly 520 located on the left and right sides of the water intake chamber 210. Furthermore, as the required filter flow rate gradually increases, the dimensions of the first filter assembly 510 and the second filter assembly 520 also increase accordingly, further reducing their center-to-center distance. For example, the distance between the front edges of the first sidewall 214 and the second sidewall 215 is greater than the center-to-center distance between the first filter assembly 510 and the second filter assembly 520. This allows the water intake chamber 210 to have a sufficiently large size, enabling it to accommodate large water containers such as pots or basins.

[0036] The second wall 213 of the water intake cavity 210 has a dimension slightly smaller than the aforementioned center-to-center distance. The angle between the first sidewall 214 and the second sidewall 215 extending from the second wall 213 of the water intake cavity 210 and the second wall 213 is not too large to avoid interference with the first filter element assembly 510 and the second filter element assembly 520 on both sides of the water intake cavity 210. At the same time, the angle cannot be set too small to avoid the cross-section of the water intake cavity 210 being too small to accommodate common water intake containers. Exemplarily, the water intake cavity 210 also includes a third sidewall 216 and a fourth sidewall 217, both connected between the top wall 211 and the bottom wall, wherein: the first sidewall 214 is connected between the third sidewall 216 and the second wall 213, the second sidewall 215 is connected between the fourth sidewall 217 and the second wall 213, and the third sidewall 216 and the fourth sidewall 217 are arranged opposite each other in the lateral direction. When the edges of the first sidewall 214 and the second sidewall 215 have sufficient spacing (e.g., greater than the center distance between the first filter assembly 510 and the second filter assembly 520 as described above), they are connected to the first wall 101 of the embedded water purifier via the third sidewall 216 and the fourth sidewall 217, which have a small angle with the second wall 213. Figure 2B In the illustrated embodiment, the angles between the first sidewall 214 and the second sidewall 215 and the second wall 213 can both be θ1, and the angles between the third sidewall 216 and the fourth sidewall 217 and the second wall 213 can both be θ2, where θ1 > θ2. Specifically, for example, θ2 is a right angle and θ1 is an obtuse angle. This ensures that the opening of the first wall 101 exposing the water intake cavity 210 is not too large. In some embodiments, the water intake cavity 210 can be integrally formed on the first wall 101. In these embodiments, the above structure can avoid excessively large bends at the bends and prevent the edge of the opening of the water intake cavity 210 from being too close to the edge of the first wall 101 of the embedded water purifier, thereby ensuring the strength of the first wall 101 and the water intake cavity 210. In other embodiments, the water intake cavity 210 and the first wall 101 of the embedded water purifier are not integrally formed. In these embodiments, the first wall 101 has an outer side plate 250, which includes an outer side plate opening 251 that exposes the water intake cavity 210. The outer panel opening 251 is typically slightly smaller than the opening of the water intake cavity 210, thus eliminating the need for a perfect size match and reducing the precision requirements of the machining. It is also more aesthetically pleasing than embodiments where the outer panel opening 251 exposes the edge of the water intake cavity 210 more. In this case, the third sidewall 216 and the fourth sidewall 217 connect between the inner surface of the outer panel 250 and the first sidewall 214 and the second sidewall 215, forming a right angle with the inner surface of the outer panel 250. This is more convenient for cleaning than embodiments where the first sidewall 214 and the second sidewall 215 extend directly to the inner surface of the outer panel 250, forming an acute angle. Furthermore, the water intake cavity 210 has a greater depth to accommodate the water intake container.

[0037] Continue to refer toFigure 2A The first filter element assembly 510 and the second filter element assembly 520 have a small gap from the first wall 101 of the embedded water purifier. Exemplarily, along the arrangement direction of the first wall 101 and the second wall 213, the dimensions of the third side wall 216 and the fourth side wall 217 are respectively less than half the dimension of either the first side wall 214 or the second side wall 215. Therefore, the smaller third side wall 216 can be disposed in the gap between the first filter element assembly 510 and the first wall 101, and the fourth side wall 217 can also be disposed in the gap between the second filter element assembly 520 and the first wall 101. Thus, in the lateral direction, an increase in the distance between the third side wall 216 and the fourth side wall 217 will not interfere with the first filter element assembly 510 and the second filter element assembly 520. This not only makes the embedded water purifier more aesthetically pleasing but also allows the opening of the water intake chamber 210 to have a larger lateral dimension.

[0038] For example, at least one of the third sidewall 216 and the fourth sidewall 217 is provided with a vent 400. This arrangement of the vent 400 is more concealed, making the appearance of the embedded water purifier more streamlined. The vent 400, which blows air outwards, can be positioned on the third sidewall 216 and / or the fourth sidewall 217 to guide the airflow and prevent it from affecting the user experience.

[0039] Exemplarily, each of the first filter assembly 510 and the second filter assembly 520 includes a filter element and a filter holder. Figure 2A and Figure 3 As shown, the first filter element assembly 510 includes a first filter element 511 and a first filter base 512. The first filter element 511 can be the reverse osmosis filter element described above. The second filter element assembly 520 includes a second filter element 521 and a second filter base 522. The second filter element 521 can be the pre-filter element described above. Of course, the first filter element 511 and the second filter element 521 can be of different types, and the corresponding filter bases can also have different numbers of water passage openings. The filter base is installed at the bottom of the inner cavity 103, and the filter element is vertically and detachably installed to the filter base. For example, the filter element can be connected to the filter base by a suitable method such as straight insertion or twist clamping. Thus, users can replace the filter element more conveniently without making complicated water passage connections.

[0040] Exemplarily, the filter holder includes a locking mechanism that locks the filter cartridge in place when it is installed. In some embodiments, the user only needs to insert the filter cartridge into the filter holder and press it until it cannot be pressed any further to lock the filter cartridge, making installation simpler and more reliable. The horizontal cross-sectional area of ​​the filter cartridge is smaller than that of the filter holder, and the filter cartridge's horizontal projection falls entirely within the horizontal projection of the filter holder. Therefore, when designing the relationship between the filter cartridge assembly and the water intake chamber 210, the filter holder with the larger cross-sectional area can be used as a reference. In some embodiments, one surface of the filter holder can be constructed with a chamfered structure to accommodate the first sidewall 214 and the second sidewall 215 of the water intake chamber 210. In the embodiment shown in the figure, at least a portion of the filter holder's projection on the horizontal plane is fan-shaped, and the minimum distance between the filter holder and the water intake chamber 210 is less than a preset threshold. The preset threshold can be determined according to the specific dimensions of the embedded water purifier to ensure that the dimensions of the embedded water purifier meet the requirements without the filter holder contacting the water intake chamber 210.

[0041] As shown in the figure, the locking mechanism includes a button 530, which allows the user to easily eject the filter element from the filter holder. To reduce production costs, the filter holders of the first filter element assembly 510 and the second filter element assembly 520 may differ only in their water inlet, while maintaining the same overall shape. The portion enclosed by the front and side surfaces of the filter holder can be configured to project in a fan shape onto the horizontal plane, thus providing sufficient space to accommodate the button 530. Furthermore, the filter holder can avoid interference with the water intake chamber 210, thereby meeting the design requirements of an embedded water purifier.

[0042] Reference Figures 3 to 5 Exemplarily, the housing assembly 100 includes a rear housing 110 and a front door 120. The rear housing 110 contains replacement openings 540 for a first filter element assembly 510 and a second filter element assembly 520. The front door 120 is closably connected to the rear housing 110, and the front door 120 and the rear housing 110 together form an inner cavity 103. A water intake cavity 210 is formed on the front door 120. Exemplarily, the front door 120 can be opened by pivoting, translating, or other means. In one embodiment, a hinge is provided between the front door 120 and the rear housing 110, allowing it to be opened by pivoting. In another embodiment, the front door 120 can be opened by sliding laterally. When open, the inner cavity 103 is exposed. Only one front door 120 is shown in the figure; in embodiments not shown, there may be more than one front door 120, for example, a double-door structure. Users can directly open the front door 120 to expose the replacement openings 540 and disassemble and replace the filter elements through the replacement openings 540. Therefore, users do not need to remove or pull the built-in water purifier from its housing, reducing workload and decreasing the possibility of it tipping over due to instability when pulled out of the housing.

[0043] For example, the front door 120 is pivotally connected to the rear housing 110 between an open position and a closed position about a pivot axis extending in a vertical direction. Figure 3 As shown, a first pivot hole 111 can be provided on the rear shell 110, and a second pivot hole 230 can be provided on the front door 120. The first pivot hole 111 and the second pivot hole 230 are concentrically arranged and fitted with rivets or screws. Thus, the front door 120 can pivot about the pivot axis. The side-opening door usually does not hinder the user's operation and does not require an additional retaining structure, combining cost and convenience.

[0044] Exemplarily, the rear housing 110 is provided with a first partition and a second partition. The first partition divides the inner cavity 103 into a first filter cartridge compartment 1032 for accommodating the first filter cartridge assembly 510, and the second partition divides the inner cavity 103 into a second filter cartridge compartment 1033 for accommodating the second filter cartridge assembly 520. In embodiments where the first filter cartridge assembly 510 and the second filter cartridge assembly 520 include a filter cartridge holder and a filter cartridge, and both are replaceable, the user may need to replace the filter cartridge during routine maintenance. Since water may remain in the filter cartridge during disassembly, water may flow into the inner cavity 103 when the user replaces the filter cartridge, potentially causing electric shock and damage. The first filter cartridge compartment 1032 and the second filter cartridge compartment 1033 can isolate the first filter cartridge assembly 510, the second filter cartridge assembly 520, and other components in the inner cavity 103. The first partition and the second partition can be provided at least in the lower half, preferably extending from the bottom to the top of the inner cavity 103, thereby effectively preventing water from flowing into the electrical component area. Wherein:

[0045] The front sides of the first filter compartment 1032 and the second filter compartment 1033 are open and connected to the filter replacement opening 540. The front door 120 is a single unit. When the front door 120 is in the closed position, it simultaneously covers the front sides of the first filter compartment 1032 and the second filter compartment 1033. This allows the outer panel 250 of the front door 120 to be a single piece without gaps, making it more aesthetically pleasing and easier to clean.
