Description

Technical Field

[0001] The present invention relates to the technical field of water treatment, and in particular to an embedded beverage machine. Background Art

[0002] As the world changes, people's demands for drinking water quality are becoming increasingly stringent, and beverage dispensers have become popular and widely accepted. Available beverage dispensers include desktop dispensers, under-the-sink dispensers, and built-in dispensers, all of which can purify tap water or water from a water tank to provide users with high-quality, purified water.

[0003] Built-in beverage dispensers are popular among users because they don't take up desk space and can be connected to a water source such as tap water, making them convenient to use. These dispensers can be placed in sideboards, allowing users to easily access water while dining.

[0004] Sideboards are typically small. Currently, built-in beverage dispensers on the market are becoming increasingly versatile, with more internal components and a larger depth. This makes them difficult to install in smaller sideboards. Even if they can be installed, the gap between the back of the dispenser and the inner wall of the sideboard is too small, causing significant bending in the wiring. Summary of the Invention

[0005] To at least partially address the problems existing in the prior art, some embodiments of the present invention provide an embedded beverage dispenser, comprising: a rear shell and a front door, the front door being closably disposed on the rear shell, the front door and the rear shell together forming an inner cavity; a refrigeration assembly disposed within the inner cavity; a filter assembly, the filter assembly comprising a first filter assembly and a second filter assembly, the first filter assembly and the second filter assembly being detachably disposed within the inner cavity and located on first and second sides of the refrigeration assembly along a lateral direction, the filter assembly being detachable when the front door is open; and a water intake nozzle disposed within the rear shell and located between the first filter assembly and the second filter assembly, wherein: a central portion of the front door is recessed inwardly into the space between the first filter assembly and the second filter assembly to form a water intake cavity, the front door further comprising a water intake opening, at least a portion of the water intake opening being disposed on a top wall of the water intake cavity, the water intake opening exposing the water intake nozzle when the front door is closed. Thus, the depth of the embedded beverage dispenser is effectively shortened. The built-in beverage dispenser's center of gravity is relatively forward, and the front-opening door allows users to easily open the front door to maintain the filter assembly without having to remove the heavy built-in beverage dispenser from its storage space. This effectively reduces the risk of the built-in beverage dispenser tipping over during maintenance. Furthermore, users can still dispense water even when the front door is closed, providing a positive user experience.

[0006] For example, the lateral width of the water intake chamber increases in the direction away from the inner cavity; the lateral width of the portion of the water intake chamber away from the inner cavity is greater than the lateral width of the gap between the first filter assembly and the second filter assembly. In this way, the layout can be reasonably arranged when the size of the embedded beverage machine is limited and there are many components inside. On the one hand, it ensures that the portion of the water intake chamber away from the inner cavity has a sufficiently large opening to facilitate users to place various types of water intake containers. In addition to cups, they can also place kettles, pots, basins, etc. On the other hand, the portion of the water intake chamber close to the inner cavity is located in the gap, which can make the water intake chamber have sufficient depth. During the user's water intake process, the water intake container placed in the water intake chamber is not easy to fall.

[0007] Exemplarily, the rear wall of the rear housing has a recessed portion recessed toward the inner cavity, a first rear air vent, and a second rear air vent, the first rear air vent being located within the recessed portion. An air inlet and an air outlet are provided on one or more of the side walls, top wall, bottom wall, and front door of the rear housing. The refrigeration assembly includes a compressor, a condenser, and a first cooling fan. The first cooling fan is located at the rear of the inner cavity and adjacent to the front wall of the recessed portion. The first cooling fan is used to dissipate heat from the condenser and the compressor. The air outlet of the first cooling fan is directed toward the first rear air vent, thereby forming a first heat dissipation path sequentially passing through the air inlet, the inner cavity, and the recessed portion. The embedded beverage dispenser further includes a second cooling fan disposed within the inner cavity. The air inlet of the second cooling fan is connected to the second rear air vent, thereby forming a second heat dissipation path sequentially passing through the recessed portion, the inner cavity, and the air outlet. The air inlet can continuously replenish cool air. The cool air passes through the compressor and condenser, and most of the heat is blown to the rear of the housing assembly through the first rear air vent. This prevents the hot air from directly reaching the user. High-temperature air at the rear of the built-in beverage dispenser is at least partially transferred to the front of the built-in beverage dispenser, preventing heat accumulation in the confined space and potentially leading to overheating and performance degradation. Heat is initially dissipated at the rear of the built-in beverage dispenser, and the airflow directed toward the user is relatively low in temperature, virtually minimizing the user experience. The recessed portion effectively prevents heat from accumulating outside the built-in beverage dispenser due to heat not being blown away by the first cooling fan.

[0008] Exemplarily, a partition is provided within the rear housing to separate the inner cavity into a first filter cartridge compartment housing the first filter assembly, a second filter cartridge compartment housing the second filter assembly, and a main body compartment housing the refrigeration assembly. The air inlet communicates with the main body compartment via the first filter cartridge compartment, and the air outlet communicates with the main body compartment via the second filter cartridge compartment. The partition can isolate at least the main body compartment from the lower halves of the first and second filter cartridge compartments, effectively preventing water from flowing into the electrical component area. On the one hand, airflow drawn from the rear of the built-in beverage dispenser can be buffered in the second filter cartridge compartment and directed from the air outlet of the second cooling fan located above to the air outlet located below, further preventing hot air from being blown onto the user. On the other hand, using the first and second filter cartridge compartments as airflow channels eliminates the need for additional guide channels within the inner cavity, simplifying the inner cavity structure. Similarly, the first filter cartridge compartment can also guide airflow from the air inlet, simplifying the inner cavity structure. The second filter assembly may include a reverse osmosis filter element as a central filter element. When the second cooling fan draws hot air into the second filter element compartment, the temperature of the reverse osmosis filter element may be increased, thereby increasing the water outlet flow of the reverse osmosis filter element to a certain extent.

[0009] For example, the air inlet includes a front air inlet located on the front door, and the air outlet includes a front air outlet located on the front door. The front air inlet can provide a better cooling effect. Placing the front air outlet on the front door can also improve the smoothness of airflow and enhance the heat dissipation effect.

[0010] Exemplarily, the front door comprises an inner lining panel, with a water intake cavity formed by a recessed portion of the inner lining panel. The water intake cavity has first and second sidewalls that oppose each other laterally, with a front air inlet and a front air outlet located on the first and second sidewalls, respectively; and an outer panel that covers the outer side of the inner lining panel and includes an outer panel opening that exposes the water intake cavity. The front door can be assembled from the outer panel and the inner lining panel. The outer panel can be made of a different material than the inner lining panel, and the production process is relatively simple and cost-effective. The outer panel is aesthetically pleasing and has no cracks on its surface that easily accumulate dirt, making it easy to clean. Placing the front air inlet on the first sidewall makes it less accessible to users, preventing accidental blockage during use. The front air outlet, which may emit hot air, is located on the second sidewall, directing the hot air laterally rather than directly toward the user, thereby improving the user experience.

[0011] Exemplarily, the first side wall includes a first straight wall and a first oblique wall, the first oblique wall is inclined toward the outside of the water intake cavity with its back to the inner cavity, the first straight wall is connected to the side of the first oblique wall away from the inner cavity and extends along the depth direction, and the depth direction is perpendicular to the lateral direction, the second side wall includes a second straight wall and a second oblique wall, the second oblique wall is inclined toward the outside of the water intake cavity with its back to the inner cavity, the second straight wall is connected to the side of the second oblique wall away from the inner cavity and extends along the depth direction, and the front air inlet and the front air outlet are respectively located on the first straight wall and the second straight wall. The first straight wall and the second straight wall are connected between the inner surface of the outer plate and the first oblique wall and the second oblique wall, and can form a right angle with the inner surface of the outer plate. It is more convenient to clean. The front air inlet and the front air outlet are respectively located on the first straight wall and the second straight wall. Not only are the front air inlet and the front air outlet difficult to see from the front, but the airflow path is further deflected, which will not affect the user experience.

[0012] Exemplarily, the refrigeration assembly includes a cold tank, an ice-making assembly, a compressor, and a condenser. The cold tank is adjacent to the rear wall of the water intake chamber. The ice-making assembly includes an ice-making mechanism and a motor that drives the ice-making mechanism. The ice-making mechanism is disposed within the cold tank, with the motor located outside the cold tank and above the water intake chamber. The compressor is located below the cold tank, and the condenser is located behind the compressor. Thus, the ice-making mechanism disposed within the cold tank is maintained at a lower temperature than the cold tank and is isolated from the outside world, resulting in a cleaner ice-making environment. The motor is disposed above the water intake chamber, effectively utilizing the gap within the inner chamber and improving space utilization. The compressor and condenser disposed below not only lower the center of gravity of the embedded beverage dispenser but also place the two components generating the most heat closest to the first cooling fan, achieving optimal heat dissipation.

[0013] For example, the built-in beverage dispenser further includes an ice receiving tray. An ice receiving opening is provided on the wall of the water intake chamber. The ice receiving tray is retractably connected to the cold can via the ice receiving opening. The ice receiving tray is used to receive ice cubes produced by the ice-making assembly. Thus, ice cubes produced by the ice-making assembly can be temporarily stored in the ice receiving tray. The ice receiving tray can also isolate the interior of the ice-making assembly from the outside world, thereby improving the interior hygiene of the ice-making assembly and enhancing ice-making efficiency.

[0014] For example, the built-in beverage dispenser also includes a heating assembly. The heating assembly's water inlet is connected to the filter assembly for heating the purified water produced by the filter assembly. The heating assembly's water outlet is connected to the water intake nozzle. The heating assembly is located between the first and second filter assemblies. The heating assembly can be positioned close to the water intake nozzle, shortening the piping. This placement also keeps it away from the first cooling fan, reducing heat loss and effectively utilizing space within the built-in beverage dispenser.

[0015] For example, the built-in beverage dispenser further includes: a booster pump located behind one of the first and second filter assemblies; and an electrical control board and a power adapter located behind the other of the first and second filter assemblies. This allows the internal space on both sides of the recessed portion at the rear of the built-in beverage dispenser to be utilized, further improving space utilization within the built-in beverage dispenser.

[0016] Exemplarily, the water intake opening extends from the top wall of the water intake chamber to the rear wall of the water intake chamber. For the embodiment in which the front door moves horizontally, the water intake nozzle can enter the water intake chamber when the front door is closed, and the water intake opening will not form a large gap.

[0017] For example, a base is provided within the inner cavity, and the water intake nozzle is fixed to the base. The bottom surface of the base exposes the outlet of the water intake nozzle. When the front door is in the closed position, the top wall of the water intake cavity abuts the bottom surface of the base. This facilitates assembly of the embedded water dispenser and allows the rear housing and the water intake nozzle to be made of different materials and processes, improving product quality and reducing costs.

[0018] For example, a seal is provided on the bottom surface of the base and / or the wall of the water intake chamber. When the front door is closed, the seal is clamped between the bottom surface of the base and the wall of the water intake chamber, and the seal surrounds the water intake spout. This prevents water from seeping into the rear housing through the water intake opening when water is being drawn. Even if water does not flow into the rear housing, steam may pass through the water intake opening when the user draws hot water. The provision of a seal prevents steam from adversely affecting the operating panel.

[0019] Exemplarily, the built-in beverage dispenser further includes: an electronic control board disposed within the rear housing; and an operating panel disposed on the front door, the operating panel being electrically connected to the electronic control board at least when the front door is closed. Placing the operating panel on the front door allows the user to operate the device without opening the front door. With the operating panel located on the front door, moisture or dirt is virtually eliminated from entering the space between the operating panel and the transparent portion of the front door, ensuring a clear display at all times.

[0020] For example, a first conductive contact is provided in the rear housing and electrically connected to the electronic control panel. A second conductive contact is provided on the front door and electrically connected to the operation panel. The first and second conductive contacts are electrically coupled when the front door is closed. This eliminates the need for a cable between the front door and the rear housing, preventing cable breakage from prolonged bending or accidental door opening. Furthermore, the circuit design is relatively simple and cost-effective.

[0021] Exemplarily, each of the first filter assembly and the second filter assembly includes: a mounting seat, the mounting seat being arranged at the top of the inner cavity, the mounting seat having a filter seat water interface extending in the depth direction, the depth direction being perpendicular to the lateral direction; and a filter element, the filter element including a mounting head located at the top thereof, the mounting head having a filter element water interface extending in the depth direction, the mounting head being detachably mounted to the mounting seat along the depth direction, wherein, in the mounted state where the mounting head is mounted to the mounting seat: the filter element water interface and the filter seat water interface are interconnected; and the filter element is hoisted in the inner cavity. The above scheme can be applied to embedded beverage machines with a relatively compact internal arrangement, without the need to reserve additional moving space for the removal and assembly of the filter element. The removal and installation of the filter element can be done by pulling out the filter element compartment along the first direction, or inserting the filter element compartment in the opposite direction to the first direction, which is simple to operate. Moreover, the filter element water interface and the filter seat water interface extend in the horizontal direction, so there is less water accumulation inside, making replacement more convenient.

[0022] Illustratively, each of the first and second filter assemblies includes a filter cartridge and a filter holder, the filter holder being disposed within a rear housing. The filter cartridge is removably mounted to the filter holder, and the filter holder is pivotable about an axis extending laterally between a stowed position and an inclined position. When the filter holder is in the stowed position, the filter cartridge mounted on the filter holder is housed within the rear housing; and when the filter holder is in the inclined position, at least a portion of the filter cartridge mounted on the filter holder extends outside the rear housing. Particularly for embedded beverage dispensers with a relatively small filter cartridge compartment, the filter holder can be pivoted so that the filter cartridge can be partially or completely exposed from the compartment during removal and installation, thereby facilitating handling of the filter cartridge. Furthermore, mounting the filter cartridge to the filter holder outside the compartment allows for sufficient movement of the filter cartridge along the extended direction. For embedded beverage dispensers whose total length, before the filter cartridge is mounted on the filter holder, is greater than the cartridge compartment, the filter cartridge can be mounted to the filter holder outside the compartment in the aforementioned manner, and after installation, the filter cartridge and filter holder can be accommodated within the compartment.

[0023] Exemplarily, the beverage dispenser further includes a retaining member movably disposed on the top of the rear housing between a retaining position and a release position. The retaining position is located below the release position. When the retaining member is in the retaining position, the filter cartridge is retained in the rear housing by the retaining assembly. When the retaining member is in the release position, the filter cartridge can be removed from the rear housing. The retaining member can prevent the filter cartridge from loosening and leaking, or even from accidentally falling off.

[0024] For example, the depth of the built-in beverage dispenser is smaller than the standard size, so that it can be applied to storage spaces of conventional specifications such as sideboards, dish racks, cabinets, etc., and can also be applied to storage spaces with shorter depth.

DETAILED DESCRIPTION

[0042] In the following description, a large amount of detail is provided to facilitate a thorough understanding of the present invention. However, it will be appreciated by those skilled in the art that the following description merely illustrates preferred embodiments of the present invention, and that the present invention 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.

[0043] To provide a thorough understanding of the embodiments of the present invention, a detailed description of the structure will be provided in the following description. It should be understood that the implementation of the embodiments of the present invention is not limited to the specific details familiar to those skilled in the art. Preferred embodiments of the present invention are described below in detail, but in addition to these detailed descriptions, the present invention may also have other embodiments.

[0044] Combined with reference Figure 1-Figure 3 This application provides a built-in beverage dispenser. The built-in beverage dispenser may include a rear housing 100 and a front door 200. The rear housing 100 may be made of materials such as plastic or metal. In the embodiment shown in the figure, the rear housing 100 may be made using sheet metal processing, which provides higher strength and lower production costs. For ease of understanding, in this application, the side of the built-in beverage dispenser facing the user during use may be considered the front, while the side facing away from the user may be considered the rear of the built-in beverage dispenser. The dimensions of the front and rear surfaces of the built-in beverage dispenser are referred to as the depth.

[0045] The front door 200 is disposed on the rear housing 100 in an openable and closable manner. The front door 200 and the rear housing 100 together form an inner cavity 300. For example, the front door 200 can be opened by pivoting, sliding, or the like. In one embodiment, a hinge is provided between the front door 200 and the rear housing 100, and the front door 200 is opened by pivoting. In another embodiment, the front door 200 can be opened by sliding laterally. When in the open state, the inner cavity 300 can be exposed. The figure shows only one front door 200. In embodiments not shown, there may be more than one front door 200, for example, a double-door structure.

[0046] The built-in beverage dispenser includes a refrigeration assembly 400 disposed within the inner cavity 300. The refrigeration assembly 400 may include a semiconductor refrigeration element, a refrigeration element with a refrigerant circulation circuit, or the like. In short, the refrigeration assembly 400 can transfer heat from the cold end to the hot end. In some embodiments, the refrigeration assembly 400 can be used only to prepare cold water; in other embodiments, the refrigeration assembly 400 can also be used to make ice.

[0047] The built-in beverage dispenser also includes a filter assembly 500, which includes a first filter assembly 510 and a second filter assembly 520. The first filter assembly 510 and the second filter assembly 520 are removably disposed within the inner cavity 300 and located on first and second sides of the refrigeration assembly 400 along the lateral direction. The depth of the built-in beverage dispenser and the lateral direction of the built-in beverage dispenser are perpendicular to each other. Taking the built-in beverage dispenser in normal use as an example, when looking directly at the front door of the built-in beverage dispenser, the left-right direction is the lateral direction, and the front-to-back direction is the depth direction. Each of the first filter assembly 510 and the second filter assembly 520 can be removable from the filter seat 540 by providing a filter element 530 and a filter seat 540. The filter elements 530 can each include a pre-filter element and a central filter element, or a central filter element and a post-filter element. The central filter element performs the primary filtering function. Taking the first filter assembly 510 and the second filter assembly 520 as an example, representing the pre-filter and central filter, respectively, the pre-filter can be made of PP cotton, activated carbon, non-woven fabric, or a composite of any two or more of these. It is located before the central filter and is used to perform preliminary filtration on the water entering the central filter to extend the service life of the central filter. The central filter can include a reverse osmosis filter, an ultrafiltration filter, a nanofiltration filter, or a composite of any two or more of these filter elements 530. For reverse osmosis and nanofiltration filter elements, the water needs to be pressurized before entering the filter element 530. In this case, the embedded beverage dispenser can also include a booster pump 900. This allows for the provision of high-quality purified water to the user. When the front door 200 is open, the filter assembly 500 can be at least partially exposed to the outside, allowing the user to remove and install the filter assembly 500 through the open opening.

[0048] The built-in beverage dispenser may include a water spout 110, which is disposed within the rear housing 100 and positioned between the first filter assembly 510 and the second filter assembly 520. The water spout 110 is used to provide the user with water during the water dispensing operation. The front door 200 includes a water intake chamber 210, which is recessed from the center of the front door 200 into the space between the first filter assembly 510 and the second filter assembly 520. Users can place a water container on the bottom surface of the water intake chamber 210, eliminating the need to constantly hold the container during water dispensing. In this case, the water spout 110 can be located within the water intake chamber 210. The recessed shape of the water intake chamber 210 into the inner cavity 300 eliminates any protrusions from the front surface of the built-in beverage dispenser. This prevents users from bumping into protruding parts and causing injury or damage to the built-in beverage dispenser during use. The front door 200 may be provided with a water intake opening 211. At least a portion of the water intake opening 211 is disposed on the top wall of the water intake chamber 210. When the front door 200 is closed, the water intake opening 211 exposes the water intake spout 110. In other words, the top wall of the water intake chamber 210 does not obstruct the water intake spout when the front door 200 is closed. This allows users to access water without opening the front door 200 during daily use, simplifying operation.

[0049] For embedded beverage machines, the water intake chamber 210, the filter element 530 assembly and the refrigeration assembly 400 have relatively large horizontal dimensions. The components that have a greater impact on the depth dimension are arranged side by side in the width direction, so that a portion of each component can be accommodated in the gaps between other components in the depth direction. As a result, the depth dimension of the embedded beverage machine is effectively shortened. The center of gravity of the embedded beverage machine is relatively forward. Through the front-opening door structure, the user can more conveniently open the front door 200 to maintain the filter assembly 500 without having to pull the heavier embedded beverage machine out of the storage space, effectively reducing the risk of the embedded beverage machine tipping over due to an unstable center of gravity during maintenance. Moreover, when the front door 200 is in the closed state, the user can also perform the water extraction operation, which provides a good user experience.

[0050] As mentioned above, the embedded beverage machine can be suitable for a storage space with only a small depth. For example, the depth of the embedded beverage machine is smaller than the standard size. Taking the common embedded beverage machines on the market as an example, it is suitable for a storage space with a height of 460mm and a width of 600mm or more. Therefore, the height and width of the embedded beverage machine are about 455mm×595mm. And its depth can reach 520mm. Taking into account the heat dissipation at the rear, the depth requirement for the storage space is at least 550mm. The depth of the embedded beverage machine of this application can be compressed to 330mm, and the height and width are the same as those of a conventional embedded beverage machine. In this way, it can be suitable for storage spaces of conventional specifications such as sideboards, dish racks, cabinets, etc., and it can also be suitable for storage spaces with a shorter depth.

[0051] For example, the left-right width of the water intake chamber 210 can increase in the forward direction. Specifically, in the lateral direction, the portion of the water intake chamber 210 distal to the inner cavity 300 can be wider than the gap between the first filter assembly 510 and the second filter assembly 520, while the portion of the water intake chamber 210 proximal to the inner cavity 300 can be narrower than the gap, thereby positioning the portion of the water intake chamber 210 proximal to the inner cavity 300 within the gap. In some embodiments, the portion of the water intake chamber 210 distal to the inner cavity 300 and the portion proximal to the inner cavity 300 can be directly connected by a straight wall, resulting in a generally trapezoidal horizontal cross-section of the water intake chamber 210. In other embodiments, the wall connecting the portion distal to the inner cavity 300 and the portion proximal to the inner cavity 300 can have a curve or bend, for example, the horizontal cross-section of the water intake chamber 210 can have a stepped shape. In summary, the wall connecting the portion of the water intake chamber 210 distal to the inner cavity 300 and the portion proximal to the inner cavity 300 can provide clearance for the first filter assembly 510 and the second filter assembly 520.

[0052] This allows for a well-designed layout even within a built-in beverage dispenser with limited depth and numerous internal components. This ensures that the portion of the water intake chamber 210 away from the inner cavity 300 has a sufficiently large opening to accommodate various water containers, including cups, pots, pans, and basins. Furthermore, the portion of the water intake chamber 210 near the inner cavity 300 is located within the gap, ensuring sufficient depth. This prevents water containers placed within the water intake chamber 210 from falling out during the user's water intake process.

[0053] Combined with reference Figure 4 and Figure 5 For example, the refrigeration assembly 400 includes a compressor 420, a condenser 430, and a first cooling fan 610. The first cooling fan 610 is located at the rear of the inner cavity 300 and adjacent to the front wall of the recessed portion 190. The first cooling fan 610 is used to dissipate heat from the condenser 430 and the compressor 420. The air outlet of the first cooling fan 610 faces the first rear air vent 140, forming a first heat dissipation path that passes through the air inlet, the inner cavity 300, and the recessed portion 190 in sequence. As a result, the air inlet can continuously replenish cold air. The cold air passes through the compressor 420 and condenser 430, and most of the heat can be blown to the rear of the housing assembly through the first rear air vent 140. This prevents the hot air from directly facing the user.

[0054] The built-in beverage dispenser also includes a second cooling fan 620, which is disposed within the inner cavity 300. The air inlet of the second cooling fan 620 communicates with the second rear air vent 150, forming a second heat dissipation path that sequentially passes through the recessed portion 190, the inner cavity 300, and the air outlet. The rear of the built-in beverage dispenser forms a high-temperature area due to the first cooling fan 610. The second cooling fan 620 draws air from the high-temperature area through the first rear air vent 140 and blows the higher-temperature air to the air outlet. The second cooling fan 620 is disposed within the inner cavity 300 and may include, but is not limited to, an axial flow fan, a centrifugal fan, or the like. In some embodiments, the area where the second cooling fan 620 is located is isolated from the rest of the inner cavity 300, so that only air entering through the second rear air vent 150 can be blown by the fan assembly to the front air outlet 240. In another embodiment, air from other areas of the inner cavity 300 and air entering through the second rear air vent 150 can be blown to the air outlet together.

[0055] Air inlets and outlets are provided on one or more of the side walls, top wall, and bottom wall of the rear housing 100, as well as the front door 200. The air inlets at different locations allow airflow within the embedded beverage dispenser to converge from various directions to the first cooling fan 610, thereby dissipating heat from various components requiring heat dissipation. The rear wall of the rear housing 100 includes a recessed portion 190 that is recessed toward the inner cavity 300, a first rear air outlet 140, and a second rear air outlet 150. The first rear air outlet 140 is located within the recessed portion 190. In some usage scenarios, the embedded beverage dispenser may place the rear wall of the housing against the inner wall of the space containing the embedded beverage dispenser. In this case, the provision of the recessed portion 190 can form an air circulation path between at least the rear portion of the embedded beverage dispenser and the inner wall of the space, thereby preventing a situation where the heat dissipation component is completely unable to dissipate heat while the fan component is unable to draw air away from the heat dissipation component.

[0056] As a result, the high-temperature air at the rear of the built-in beverage dispenser can be at least partially transferred to the front of the built-in beverage dispenser, preventing heat accumulation in the confined space, which could lead to overheating and performance degradation. Heat is initially dissipated at the rear of the built-in beverage dispenser. Compared to directing air from the first cooling fan 610 directly to the front of the built-in beverage dispenser, this solution delivers lower air temperature toward the user, virtually eliminating any impact on the user experience. The recessed portion 190 effectively prevents heat from accumulating outside the built-in beverage dispenser due to heat not being blown by the first cooling fan 610.

[0057] For example, the built-in beverage dispenser further includes a booster pump 900 located behind one of the first filter assembly 510 and the second filter assembly 520, and an electronic control board 1000 and a power adapter 1010 located behind the other of the first filter assembly 510 and the second filter assembly 520. Thus, the space in the inner cavity 300 on both sides of the recessed portion 190 at the rear of the built-in beverage dispenser can be utilized, further improving the space utilization inside the built-in beverage dispenser.

[0058] For example, a partition 160 may be provided within the rear housing 100 to separate the main compartment 173 within the inner cavity 300, which houses the refrigeration assembly 400. As described above, the water inlet nozzle 110 is located in a portion of the main compartment 173 away from the inner cavity 300. Water may spill when drawing water, or residual water may drip after drawing water. The main compartment 173 prevents water from entering the refrigeration assembly 400 and other components located within the main compartment 173. The inner cavity 300 may also be divided by the partition 160 into a first filter cartridge compartment 171, which houses the first filter assembly 510, and a second filter cartridge compartment 172, which houses the second filter assembly 520. In embodiments where the first and second filter assemblies 510, 520 include a filter seat 540 and a filter cartridge 530, and both are replaceable, users may need to replace the filter cartridge 530 themselves during routine maintenance. Since residual water may remain in the filter cartridge 530 when the filter cartridge 530 is removed, water may flow into the inner cavity 300 when the user replaces the filter cartridge 530, causing electric shock and damage. The first filter cartridge compartment 171 and the second filter cartridge compartment 172 can separate the first filter assembly 510, the second filter assembly 520, and the components in the main body compartment 173. The partition 160 can separate at least the lower half of the main body compartment 173 from the first filter cartridge compartment 171 and the second filter cartridge compartment 172, thereby effectively preventing water from flowing into the electrical component area. As shown in the figure, the partition 160 can also completely separate the first filter assembly 510, the second filter assembly 520 from the components in the main body compartment 173.

[0059] The air inlet is connected to the main body compartment 173 via the first filter cartridge compartment 171, and the air outlet is connected to the main body compartment 173 via the second filter cartridge compartment 172. On the one hand, the airflow drawn from the rear of the embedded beverage machine can be buffered in the second filter cartridge compartment 172 and guided from the air outlet of the second cooling fan 620 located above to the air outlet located below, which can further prevent the hot air at a higher temperature from being blown onto the user. On the other hand, by using the first filter cartridge compartment 171 and the second filter cartridge compartment 172 as channels for the airflow, there is no need to provide an additional guide channel in the inner cavity 300, which can simplify the structure of the inner cavity 300. Similarly, the first filter cartridge compartment 171 can also guide the airflow at the air inlet, simplifying the structure of the inner cavity 300.

[0060] The central filter element may include a reverse osmosis filter element. The pore size of the reverse osmosis filter element is 0.1 nanometers (one-millionth of a hair), and the number of bacteria and viruses that are generally invisible to the naked eye is 10 times that of the reverse osmosis filter element. Therefore, only water molecules and some mineral ions beneficial to the human body can pass through, while other impurities and heavy metals are discharged from the concentrated water outlet, providing users with high-quality purified water. The second filter assembly 520 may include a reverse osmosis filter element as the central filter element. When the second cooling fan 620 draws hot air into the second filter element compartment 172, the temperature of the reverse osmosis filter element can be increased, thereby increasing the water outlet flow of the reverse osmosis filter element to a certain extent.

[0061] For example, the air inlet comprises a front air inlet 230 located on the front door 200, and the air outlet comprises a front air outlet 240 located on the front door 200. Because the air in front of the built-in beverage dispenser is relatively cooler and is rarely obstructed by obstacles, the front air inlet 230 can provide a better cooling effect. Similarly, the front door 200 is also unobstructed compared to the side walls of the built-in beverage dispenser. Positioning the front air outlet 240 on the front door 200 can also improve airflow and heat dissipation.

[0062] Combined with reference Figure 5 and Figure 6 Exemplarily, the refrigeration assembly 400 includes a cold tank 410, an ice-making assembly, a compressor 420, and a condenser 430. The cold tank 410 is adjacent to the rear wall of the water intake chamber 210. The ice-making assembly includes an ice-making mechanism and a motor that drives the ice-making mechanism. The ice-making mechanism is disposed within the cold tank 410. The motor is located outside the cold tank 410 and above the water intake chamber 210. The compressor 420 is located below the cold tank 410, and the condenser 430 is located behind the compressor 420.

[0063] As a result, the ice-making mechanism within cold tank 410 maintains a relatively low temperature within the cold tank 410 and is isolated from the outside world, resulting in a cleaner ice-making environment. The motor is located above the water intake chamber 210, effectively utilizing the gap within the inner chamber 300 and improving space efficiency. The compressor 420 and condenser 430 located below not only lower the center of gravity of the built-in beverage dispenser but also place the two components generating the most heat closest to the first cooling fan 610, achieving optimal heat dissipation.

[0064] Exemplarily, the embedded beverage machine may further include an ice receiving box 700. An ice receiving opening 212 is further provided on the cavity wall of the water intake cavity 210. The ice receiving box 700 is retractably connected to the cold tank 410 via the ice receiving opening 212. The ice receiving box 700 is used to receive ice cubes made by the ice making assembly.

[0065] Thus, the ice cubes made by the ice-making assembly can be temporarily stored in the ice receiving box 700. The ice receiving box 700 can isolate the interior of the ice-making assembly from the outside, thereby making the interior of the ice-making assembly more hygienic and improving ice-making efficiency.

[0066] like Figure 5 As shown, illustratively, the embedded beverage machine further includes a heating component 800, the water inlet of the heating component 800 is communicated with the filter component 500, and is used to heat the purified water produced by the filter component 500, the water outlet of the heating component 800 is communicated with the water intake nozzle 110, and the heating component 800 is located between the first filter component 510 and the second filter component 520. The heating component 800 may include a water storage type or flow-through type heating element such as a hot tank, a thick film heater, or an electromagnetic heater. The heating component 800 is arranged between the first filter component 510 and the second filter component 520, and the heating component 800 can be close to the water intake nozzle 110, so that the pipeline can be shortened. And by arranging it in this position, it can be kept away from the first cooling fan 610, reducing its heat loss and making rational use of the space in the embedded beverage machine.

[0067] Combined with reference Figure 1 、 Figure 7 and Figure 8 For example, the embedded water supply machine may further include an electric control board 1000 and an operation panel 1020. The electric control board 1000 may be disposed within the rear housing 100. The electric control board 1000 may send display information to the operation panel 1020, and the display information may be displayed on components such as a digital tube 1021, an LCD display, and an indicator light 1023 of the operation panel 1020. Figure 7 As shown, the operation panel 1020 includes a digital tube 1021, a display element 1022 for displaying icons, and an indicator light 1023. In some embodiments, the operation panel 1020 can also make sounds. In the case where the operation panel 1020 is provided with input elements such as physical or touch buttons, a touch screen, etc., the operation panel 1020 can also send the acquired operation information to the electric control board 1000. Figure 2 The operation panel 1020 may include a contact spring 1024. The contact spring 1024 may be attached to a thin insulator such as glass. When a user touches the other side of the insulator, the operation panel 1020 may sense the user's touch via the contact spring 1024. The operation panel 1020 may be provided on the front door 200.

[0068] The electric control board 1000 can be implemented using various chips, such as a field programmable gate array (FPGA), a microprocessor (MPU), a programmable logic controller (PLC), a microprocessor unit (MCU), etc. The operation panel 1020 includes display elements 1022 such as indicator lights 1023 and a digital tube 1021 for display, and can also include chips such as a field programmable gate array (FPGA), a microprocessor (MPU), a programmable logic controller (PLC), a microprocessor unit (MCU), etc.

[0069] In some exemplary embodiments, the operation panel 1020 can be connected to the electronic control board 1000 in the rear housing 100 via a cable from the front door 200 to transmit power and signals. In some embodiments, the operation panel 1020 and the electronic control board 1000 are connected via wireless communication, including but not limited to Bluetooth, 315MHz radio, 433MHz radio, local area network, etc. In embodiments where wireless communication is used, the operation panel 1020 may use low-power components, allowing the operation panel 1020 to rely on the battery therein for long-term power supply. In summary, in these aforementioned embodiments, the operation panel 1020 can maintain communication with the electronic control board 1000 regardless of whether the front door 200 is closed.

[0070] In other embodiments, the operation panel 1020 can be connected to the electric control board 1000 in the rear housing 100 via, for example, near-field communication (NFC), conductive terminals, etc., to at least transmit signals. Since NFC and conductive terminals only achieve electrical coupling or contact at a relatively short distance, the operation panel 1020 is electrically connected to the electric control board 1000 only when the front door 200 is closed.

[0071] Thus, for an embedded water dispenser whose front door 200 can be opened for maintenance, the operation panel 1020 can be set on the front door 200, so that the user can operate the device without opening the front door 200. The operation panel 1020 set on the front door 200 is almost free from moisture or stains that can penetrate between the operation panel 1020 and the transparent portion of the front door 200, and the display can always be clear.

[0072] like Figure 8 As shown, for example, a first conductive contact 260 is provided in the rear housing 100, and the first conductive contact 260 is electrically connected to the electric control board 1000. A second conductive contact 180 is provided on the front door 200, and the second conductive contact 180 is electrically connected to the operation panel 1020. One of the first conductive contact 260 and the second conductive contact 180 can have a certain elasticity, including a probe, a spring, a contact plate, etc. In some embodiments, the surfaces of both the first conductive contact 260 and the second conductive contact 180 can also be coated with a precious metal layer. Figure 8In the illustrated embodiment, when the front door 200 is closed, the probe of the first conductive contact 260 can be pressed against the contact plate serving as the second conductive contact 180. This eliminates the need for a cable between the front door 200 and the rear housing 100, thus preventing cable breakage from prolonged bending or accidental door opening. Furthermore, the circuit design is simpler and less costly.

[0073] Combined with reference Figure 9 and Figure 10 For example, the front door 200 includes an inner lining plate 220, and the water intake chamber 210 is formed by the inner lining plate 220 being recessed into the inner cavity 300. The structure of the water intake chamber 210 is relatively complex. In some embodiments, the inner lining plate 220 is formed from a metal sheet, and the water intake chamber 210 thereon can be formed using sheet metal or stamping, or can be formed by welding multiple independent metal sheets. In some embodiments, the inner lining plate 220 is injection molded. The front door 200 may also include an outer panel 250, which covers the outer side of the inner lining plate 220 and includes an outer panel opening 251, which exposes the water intake chamber 210. The outer panel 250 can be integrally formed, such as a single piece of glass, ceramic, or stainless steel plate cut into the desired shape. Thus, the front door 200 can be assembled by assembling the outer panel 250 and the inner lining plate 220. The outer panel 250 can be made of a different material than the inner lining plate 220, and the production process is relatively simple and cost-effective. The one-piece outer panel 250 is more aesthetically pleasing and has no gaps on the surface where dirt easily accumulates, making it easy to clean.

[0074] The water intake chamber 210 may have a first sidewall 221 and a second sidewall 222 that oppose each other laterally. The front air inlet 230 and the front air outlet 240 are located on the first sidewall 221 and the second sidewall 222, respectively. Positioning the front air inlet 230 on the first sidewall 221 makes it less accessible to the user, preventing accidental blockage of the front air inlet 230 during use. Positioning the front air outlet 240 on the second sidewall 222 directs the hot air, which may be blown out, toward the side, rather than directly toward the user, thereby improving the user experience.

[0075] Exemplarily, the first side wall 221 includes a first straight wall 2211 and a first oblique wall 2212. The first oblique wall 2212 tilts forward toward the outside of the water intake chamber 210. The first straight wall 2211 is connected to the side of the first oblique wall 2212 away from the inner cavity 300 and extends in the depth direction. The second side wall 222 includes a second straight wall 2221 and a second oblique wall 2222. The second oblique wall 2222 tilts forward toward the outside of the water intake chamber 210. The second straight wall 2221 is connected to the side of the second oblique wall 2222 away from the inner cavity 300 and extends in the depth direction. As a result, the first oblique wall 2212 and the second oblique wall 2222 form an obtuse angle with the rear wall, making it easy to clean. The first straight wall 2211 and the first oblique wall 2212, the second straight wall 2221, and the second oblique wall 2222 also form an obtuse angle that is easy to clean. The outer plate opening 251 is typically slightly smaller than the front opening of the water intake chamber 210. This eliminates the need to perfectly match the dimensions of the water intake chamber 210, reducing the precision required for machining. Furthermore, compared to embodiments in which the outer plate opening 251 is larger, exposing the edge of the water intake chamber 210, the result is a more aesthetically pleasing design. In this case, the first straight wall 2211 and the second straight wall 2221 are connected between the inner surface of the outer plate 250 and the first and second slanted walls 2212, 2222, forming a right angle with the inner surface of the outer plate 250. This makes cleaning more convenient compared to embodiments in which the first and second slanted walls 2212, 2222 extend directly to the inner surface of the outer plate 250, forming an acute angle.

[0076] For example, the front air inlet 230 and the front air outlet 240 are located on the first straight wall 2211 and the second straight wall 2221, respectively. This makes the front air inlet 230 and the front air outlet 240 less visible from the front and further deflects the airflow path, thus minimizing the user experience. In some embodiments, the front air outlet 240 includes a barrier hood 270, which includes a fence-shaped vent. This hood not only prevents foreign matter from entering but also allows for a larger air circulation area, meeting heat dissipation requirements.

[0077] In some embodiments, the water intake opening 211 extends from the top wall of the water intake chamber 210 to the rear wall of the water intake chamber 210. In embodiments where the front door 200 moves horizontally, the water intake nozzle 110 can enter the water intake chamber 210 when the front door 200 is closed, and the water intake opening 211 does not form a large gap.

[0078] In order to simplify the manufacture of the rear shell 100, the water intake nozzle 110 is usually a structure independent of the rear shell 100. This can facilitate the assembly of the embedded water supply machine, while allowing the rear shell 100 and the water intake nozzle 110 to use different materials and processes, thereby improving the product yield and reducing costs. Therefore, the water intake nozzle 110 needs to be installed on the rear shell 100. For example, a base 120 can be provided in the inner cavity 300, and the water intake nozzle 110 is fixed on the base 120. The base 120 can be integrally formed with the rear shell 100, or it can be a separate part, providing a fixing function between the water intake nozzle 110 and the rear shell 100. In Figure 6 In the illustrated embodiment, the base 120 may extend to below the water intake spout 110. In an embodiment not shown, the base 120 may also fix the water intake spout 110 only from the side. In the embodiment where the base 120 extends to below the water intake spout 110, the bottom surface of the base 120 exposes the outlet portion of the water intake spout 110. The outlet portion may be embedded within the base 120, or may be flush with the bottom surface of the base 120 or protrude from the bottom surface. The wall of the water intake chamber 210 is provided with a water intake opening 211. When the front door 200 is in the closed position, the wall of the water intake chamber 210 is in contact with the bottom surface of the base 120, and the water intake opening 211 exposes the outlet portion of the water intake spout 110.

[0079] When taking water, if there is vibration, or there is dirt between the water intake nozzle 110 and the bottom surface of the base 120, or the outlet is damaged, it is very likely that water will flow along the inner wall of the water intake cavity 210 during the water intake process. For example, the bottom surface of the base 120 is provided with a seal 130 (refer to Figure 12 ), when the front door 200 is in the closed position, the seal 130 is clamped between the bottom surface of the base 120 and the wall of the water intake chamber 210, and the seal 130 surrounds the water intake nozzle 110. This prevents water from seeping into the interior of the rear shell 100 from the water intake opening 211 when taking water. Even if water does not flow into the interior of the rear shell 100, steam may pass through the water intake opening 211 when the user takes hot water. The provision of the seal 130 can prevent steam from adversely affecting the operation panel 1020. In other embodiments, the seal 130 can also be provided on the wall of the water intake chamber 210, which can also play the same role. In some embodiments, the seal 130 is provided on both the bottom surface of the base 120 and the wall of the water intake chamber 210.

[0080] For example, each of the first filter assembly 510 and the second filter assembly 520 includes a mounting seat 531, which is disposed at the top of the inner cavity 300 and has a filter seat 540 water interface extending in the depth direction. Figure 11As shown, each of the first filter assembly 510 and the second filter assembly 520 may further include a filter element 530', the filter element 530' including a mounting head located at the top thereof, the mounting head having a filter element water interface 533 extending along the depth direction, and the mounting head being detachably mounted to the mounting seat 531 along the depth direction. In the installation state where the mounting head is mounted to the mounting seat 531, the filter element water interface 533 is in communication with the filter seat 540 water interface; and the filter element 530' is hoisted in the inner cavity 300. In some embodiments, when the filter element 530' is in the installation state, the bottom of the filter element 530' may be in contact with the bottom of the filter element compartment. In other embodiments, the bottom of the filter element 530' does not contact the bottom plate of the filter element compartment.

[0081] The filter element 530' can be installed in a relatively narrow filter element compartment (for example, the height is close to the length of the filter element 530'), and there is no need to move the filter element 530' along the extension direction of the filter element 530' during the disassembly and assembly process. Therefore, the above solution can be applied to embedded beverage machines with a relatively compact internal arrangement, and there is no need to reserve additional moving space for the disassembly and assembly of the filter element 530'. The disassembly and installation of the filter element 530' can be done by pulling out the filter element compartment along the first direction, or inserting the filter element compartment in the opposite direction to the first direction, which is easy to operate. In addition, the filter element water interface 533 and the filter seat 540 water interface extend in the horizontal direction, so there is less water accumulation inside, which is more convenient when replacing.

[0082] like Figure 12 As shown, for example, each of the first filter assembly 510 and the second filter assembly 520 includes a filter element 530 and a filter seat 540. The filter seat 540 is disposed in the rear housing 100. The filter element 530 is detachably mounted to the filter seat 540. The filter seat 540 is pivotable about an axis extending laterally between a storage position and an inclined position. When the filter seat 540 is in the storage position, the filter element 530 mounted on the filter seat 540 is accommodated in the rear housing 100. When the filter seat 540 is in the inclined position, at least a portion of the filter element 530 mounted on the filter seat 540 extends outside the rear housing 100.

[0083] The filter element 530 may have a filter element water flow interface 533. For the pre-filter element and the central filter element that does not include a reverse osmosis filter element or a nanofiltration filter element, the filter element water flow interface 533 may only include a water inlet and a water outlet. For the central filter element that includes a reverse osmosis filter element and / or a nanofiltration filter element, since a certain proportion of concentrated water will be produced when both are working, the filter element water flow interface 533 also includes a concentrated water outlet. In some embodiments, the filter seat 540 may only serve to fix the filter element 530 without connecting the water path. In a specific embodiment, the filter element water flow interface 533 may first be connected to other water path components in the embedded beverage machine through a pipeline, and then the filter element 530 may be fixed to the filter seat 540 by screwing or inserting. The water path components in the embedded beverage machine may include one or more of a raw water inlet, a clean water outlet, a control valve, and a pump. During the installation of the filter element 530 to the filter seat 540, the filter seat 540 is in an inclined position. This eliminates the need for the user to insert their hand into the gap between the filter cartridge compartment and the filter cartridge 530 to grasp the filter cartridge. The portion of the filter cartridge 530 extending out of the compartment opening provides a fulcrum, facilitating installation. After the filter cartridge 530 is installed, the filter holder 540 can be pushed to the storage position, thereby closing the compartment opening. In another embodiment, the filter holder 540 also serves only as a fixing element. However, when the filter holder 540 is in the storage position, the filter cartridge water interface 533 can be aligned with the water channel interface below the filter holder 540 and pressure can be applied, thereby connecting the filter cartridge water interface 533 to other water channel components within the embedded beverage dispenser. In another embodiment, the filter holder 540 can have a water channel structure that provides a connection between the filter cartridge 530 and other water channel components within the embedded beverage dispenser. In some embodiments, the pivoting of the filter holder 540 can have a certain resistance, requiring a certain external force to move the filter holder 540 between the storage position and the tilted position. In other embodiments, the filter holder 540 can be pivoted with minimal force, with the filter cartridge 530 and filter holder 540 restrained by the inner walls of the built-in beverage dispenser and a shield provided at the bin opening. In some embodiments, the filter holder 540 can pivot between 30 and 60 degrees. In some embodiments, when the filter holder 540 is in an inclined position, the filter holder 540 and all filter cartridges 530 can extend out of the bin opening. In still other embodiments, the filter holder 540 can even pivot 90 degrees.

[0084] Therefore, especially for embedded beverage dispensers with a relatively small filter cartridge compartment, the filter holder 540 can be pivoted so that the filter cartridge 530 can be partially or completely exposed from the filter cartridge compartment during removal and installation, making it easier to grip the filter cartridge 530. Furthermore, installing the filter cartridge 530 to the filter holder 540 outside the filter cartridge compartment allows the filter cartridge 530 to have sufficient space to move along the extension direction. For embedded beverage dispensers whose total length is greater than the filter cartridge compartment before the filter cartridge 530 is fully installed on the filter holder 540, the filter cartridge 530 can be installed to the filter holder 540 outside the filter cartridge compartment in the aforementioned manner. Once fully installed, the filter cartridge 530 and filter holder 540 can be accommodated in the filter cartridge compartment.

[0085] Exemplarily, the beverage machine further includes a limiting member 560, which is movably disposed on the top of the rear shell 100 between a limiting position and a release position, wherein the limiting position is located below the release position. When the limiting member 560 is in the limiting position, the filter element 530 is retained in the rear shell 100 under the restriction of the limiting assembly, and when the limiting member 560 is in the release position, the filter element 530 is allowed to be removed from the rear shell 100. The limiting member 560 can be movable between the limiting position and the release position by pivoting or translating. In some embodiments, the limiting member 560 may include a pivot shaft or a slide rail. Figure 12 Taking the embodiment shown as an example, the limiting member 560 may include a clamp, which can be put on the filter element 530 to limit the position of the filter element 530.
