Description

TECHNICAL FIELD

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

[0002] With the development of the times, people's requirements for drinking water quality are higher and higher, and beverage machines have been recognized and purchased by most people due to their rich functions. The beverage machines on the market can include desktop beverage machines and embedded beverage machines, which can purify water from tap water or water tank to provide users with products such as purified water, hot water, cold water, etc.

[0003] For embedded beverage machines, they are widely welcomed because they can be set in spaces such as side cabinets, cabinets, etc., without occupying countertop space. Some embedded beverage machines have rich functions, such as ice making, cold water making, etc., and are highly integrated, capable of being embedded in relatively narrow spaces. With the integration of embedded beverage machines, how to quickly dissipate the heat generated inside to the air has become a very important problem. Most embedded beverage machines on the market dissipate heat to the rear of the machine, thereby avoiding the influence of heat on users during use.

[0004] Although dissipating heat from the rear of the machine avoids bad experience for users, it also causes the following problems: in the case that the space where the embedded beverage machine is located is very narrow, the heat at the rear will gradually accumulate, reducing the efficiency of heat dissipation, and causing the performance of the embedded beverage machine to decline. SUMMARY

[0005] To at least partially solve the problems in the prior art, some embodiments of the utility model provide an embedded beverage machine, which comprises: a shell assembly, the shell assembly forms an inner cavity, and a first rear air outlet and a front air outlet are further provided thereon, the first rear air outlet is located on the rear wall of the shell assembly, the front air outlet is located on the front wall of the shell assembly, and the first rear air outlet and the front air outlet both communicate the inner cavity with the outside; a heating assembly, the heating assembly is arranged in the inner cavity; a heat dissipation assembly, the heat dissipation assembly is located at the rear of the inner cavity, and is used for dissipating heat of the heating assembly; and a fan assembly, the fan assembly has a fan inlet and a fan outlet, wherein: the fan inlet communicates with the first rear air outlet, and the fan outlet communicates with the front air outlet via the inner cavity. The high-temperature air at the rear of the embedded beverage machine can be at least partially transferred to the front of the embedded beverage machine, thereby avoiding the accumulation of heat in the narrow space, causing the embedded beverage machine to overheat and performance to decline. The heat from the heat dissipation assembly is preliminarily dissipated at the rear of the embedded beverage machine, compared with directly blowing the heat of the heat dissipation assembly to the front of the embedded beverage machine, the air flow temperature blown to the user is lower, which hardly affects the user experience.

[0006] Exemplarily, the heat dissipation assembly comprises a fan, and a second rear air outlet is further arranged on the rear wall of the shell, the second rear air outlet communicates the inner cavity with the outside, and the air outlet of the fan faces the second rear air outlet. The heat dissipation assembly provided with the fan has better heat dissipation performance due to convection, and can quickly supplement the air in the rear part of the embedded beverage machine, thereby forming an air flow path of: air inlet→heat dissipation assembly→fan→air in the rear part of the embedded beverage machine→first rear air outlet→fan assembly→front air outlet. In this way, the heat dissipation effect is further improved.

[0007] Exemplarily, the first rear air outlet is located at the upper part of the rear wall of the shell, and the second rear air outlet is located at the lower part of the rear wall of the shell.

[0008] Exemplarily, the rear wall of the shell has a recessed part recessed towards the inner cavity, the recessed part has a recessed rear wall facing the rear, and the second rear air outlet is arranged on the recessed rear wall of the recessed part. In this case, the recessed part can form a passage for air flow between the rear part of the embedded beverage machine and the inner wall of the space, thereby avoiding the situation that the heat dissipation assembly cannot dissipate heat at all while the fan assembly cannot send air away from the heat dissipation assembly.

[0009] Exemplarily, the first rear air outlet is arranged outside the recessed part. In this way, air in a larger range can be sent, thereby improving the heat dissipation efficiency.

[0012] Exemplarily, the embedded beverage machine comprises a water connector and / or an electrical connector arranged on the recessed rear wall. The water connector arranged on the recessed part can avoid the rear wall of the shell of the embedded beverage machine being too close to the inner wall of the space, thereby causing the pipeline to be excessively bent and affecting use. In this way, the power cord can also be prevented from being excessively bent.

[0013] Exemplarily, the shell assembly further comprises a front air inlet arranged on the front wall of the shell, the front air inlet communicates the inner cavity with the outside. Since the temperature of the air in the front side of the embedded beverage machine is relatively low and is hardly blocked by an obstacle, the front air inlet can provide better cooling effect.

[0014] Exemplarily, the front wall of the shell has a water taking cavity recessed towards the inner cavity, a top of the water taking cavity is provided with a water taking nozzle, and the water taking cavity comprises a cavity top wall and a cavity bottom wall opposite to each other in the vertical direction, a cavity back wall connected between the cavity top wall and the cavity bottom wall, and a first cavity side wall and a second cavity side wall connected between the cavity top wall and the cavity bottom wall and located at two sides of the cavity back wall respectively, wherein the front air outlet and the front air inlet are arranged on the first cavity side wall and the second cavity side wall respectively.

Compared with the embodiment in which the first cavity inclined wall and the second cavity inclined wall directly extend to the inner surface of the outer side plate to form an acute angle, the cleaning is more convenient. The front air outlet and the front air inlet can further guide the airflow, avoiding the user from perceiving the airflow, thereby improving the user experience.

[0016] Exemplarily, the shell assembly comprises a rear shell and a front door, the front door is arranged in the rear shell in an openable manner, the front door and the rear shell jointly form the inner cavity, the front door comprises an inner lining plate and an outer side plate, the water taking cavity is recessed from the inner lining plate towards the inner cavity, the outer side plate covers the outside of the inner lining plate, and the outer side plate comprises an outer side plate opening, and the outer side plate opening exposes the water taking cavity.

The projections of the first cavity straight wall and the second cavity straight wall on the plane where the outer side plate is located completely fall into the outer side plate. When the front door is in the closed state, the user can only see the integrated outer side plate in the front. The outer side plate which is easy to clean can shield the gap formed by the embedded water supply machine and the space containing it to a certain extent, reduce the possibility of dust entering, and facilitate cleaning.

[0018] Exemplarily, the embedded beverage machine further comprises a first filter element assembly and a second filter element assembly.

On the one hand, the airflow drawn from the rear part of the embedded beverage machine can be buffered in the second filter element bin, and guided from the fan air outlet located above to the front air outlet located below, so as to further avoid blowing hot air with high temperature to the user. On the other hand, the first filter element bin and the second filter element bin are used as the airflow channel, without the need to set an additional guiding channel in the inner cavity, so as to simplify the structure of the inner cavity. The second filter element assembly can comprise a reverse osmosis filter element as a central filter element, which can increase the temperature of the reverse osmosis filter element when the fan assembly draws hot air into the second filter element bin, so as to increase the water flow of the reverse osmosis filter element to a certain extent. The main body bin can prevent the heating assembly, the heat dissipation assembly and the fan assembly from entering water. The first filter element bin and the second filter element bin can isolate the elements in the first filter element assembly, the second filter element assembly and the main body bin.

DETAILED DESCRIPTION

[0033] In the following description, numerous specific details are provided in order to provide a thorough understanding of the present application. One of ordinary skill in the art will realize, however, that the application can be practiced without one or more of these details. In other instances, well-known features have not been described in detail in order not to unnecessarily obscure the present application.

[0034] In order to thoroughly understand the embodiments of the present application, detailed structures will be proposed in the following description. Obviously, the implementation of the embodiments of the present application is not limited to the special details familiar to those skilled in the art. The preferred embodiments of the present application are described in detail as follows, however, in addition to these detailed descriptions, the present application can have other embodiments.

[0035] The embodiments of the present application provide an embedded beverage machine. The embedded beverage machine according to the embodiments of the present application will be introduced in detail below in combination with the drawings.

[0036] Reference is made to Figure 1 and Figure 2 The embedded beverage machine comprises a housing assembly 100, which encloses an inner cavity 103. In some embodiments, the housing assembly 100 can be made of metal, for example, by sheet metal processing. In other embodiments, the housing assembly 100 can also be made of plastic or other materials, for example, by injection molding. The inner cavity 103 can be considered as a space for accommodating all the internal components of the embedded beverage machine. In some embodiments, the inner cavity 103 can have multiple regions that are not in communication with each other, so as to separate the water circuit, the electrical circuit, and the internal air flow.

[0037] The embedded beverage machine further comprises a heating assembly, such as Figure 4 The heating assembly is disposed in the inner cavity 103. The heating assembly can comprise, for example, a circuit board, a power adapter, a hot end of a refrigeration assembly, or a condenser. In some embodiments, the embedded beverage machine can comprise a heating tank or a flow-through heater that provides hot water and does not need to be cooled, and these elements are not considered as the heating assembly of the present application. In general, all the elements of the embedded beverage machine that need to be cooled can be considered as the heating assembly.

[0038] The embedded beverage machine can comprise a heat dissipation assembly located at the rear of the inner cavity 103. For ease of understanding, the face of the embedded beverage machine facing the user when in use can be considered as the front face, and vice versa, the face of the embedded beverage machine facing away from the user can be considered as the rear face. The heat dissipation assembly is used to dissipate heat from the heating assembly. In some embodiments, the heat dissipation assembly can comprise heat dissipation fins, which can be partially disposed in the inner cavity 103 and partially extend out of the inner cavity 103. In some embodiments, the rear wall 101 of the housing assembly 100 can be directly configured as heat dissipation fins to dissipate heat by contacting air. In some embodiments, the heat dissipation assembly can concentrate heat from various parts of the embedded beverage machine to the rear of the inner cavity 103 by, for example, heat pipes. In the embodiment shown in Figure 3 The heat dissipation assembly comprises heat dissipation fins connected to the condenser 600, and a fan 700, which can suck air from the air inlet, pass through various elements that need to be cooled, reach the heat dissipation fins of the condenser 600, and be blown out of the housing assembly 100 of the embedded beverage machine by the fan. As shown, the housing assembly 100 of the embedded beverage machine can be provided with a side air inlet 130, and a front air inlet 1022 mentioned below.

[0039] The housing assembly 100 also has a first rear air inlet 1011 and a front air outlet 1021. The first rear air inlet 1011 is located on a rear wall 101 of the housing assembly 100, and the front air outlet 1021 is located on a front wall 102 of the housing assembly 100. Both the first rear air inlet 1011 and the front air outlet 1021 are in communication with the inner cavity 103. The embedded beverage machine also includes a fan assembly 400 having a fan air inlet 410 and a fan air outlet 420. The fan air inlet 410 is in communication with the first rear air inlet 1011, and the fan air outlet 420 is in communication with the front air outlet 1021 via the inner cavity 103.

[0040] As mentioned above, the heat dissipation assembly dissipates most of the heat to the rear of the housing assembly 100. Therefore, the rear of the embedded beverage machine forms a high-temperature area. The fan assembly 400 can suck air from the high-temperature area through the first rear air inlet 1011 to the fan air inlet, and blow the air with a higher temperature from the fan air outlet 420 to the front air outlet 1021. The fan assembly 400 is disposed in the inner cavity 103, including but not limited to an axial flow fan, a centrifugal fan, etc. In some embodiments, the part where the fan assembly 400 is located is separated from other parts in the inner cavity 103, so that only the air entering from the first rear air inlet 1011 can be blown by the fan assembly 400 to the front air outlet 1021. In another embodiment, the air in other parts of the inner cavity 103 and the air entering from the first rear air inlet 1011 can be blown together to the front air outlet 1021.

[0041] Thus, the high-temperature air in the rear of the embedded beverage machine can be at least partially transferred to the front of the embedded beverage machine, thereby avoiding the accumulation of heat in a small space, causing the embedded beverage machine to overheat and performance degradation. The heat from the heat dissipation assembly is preliminarily dissipated in the rear of the embedded beverage machine. Compared to directly blowing the heat from the heat dissipation assembly to the front of the embedded beverage machine, this scheme can blow air with a lower temperature to the user, which hardly affects the user experience.

[0042] In some embodiments, the suction from the fan assembly 400 creates negative pressure at the rear of the embedded beverage machine. In this case, air can be supplied to the rear of the embedded beverage machine through the mounting gap. However, if the mounting gap is small, it may be difficult to supply enough air to the rear of the embedded beverage machine through the gap, potentially leading to a further decrease in the heat dissipation efficiency of the heat dissipation assembly. Exemplarily, the heat dissipation assembly includes a fan 700, and a second rear air vent 1012 is also provided on the rear wall 101 of the housing, communicating the inner cavity 103 with the outside. The air outlet of the fan 700 faces the second rear air vent 1012. As described above, the fan 700 can blow air through the heat dissipation assembly to the rear of the embedded beverage machine. In this case, the embedded beverage machine may include an air inlet provided on the housing assembly 100, through which cooler air can be supplied to the fan 700. Therefore, not only does the heat dissipation component equipped with the fan 700 have better heat dissipation performance due to convection, but it can also quickly replenish the air at the rear of the embedded beverage machine, thus forming an airflow path of: air inlet → heat dissipation component → fan 700 → air at the rear of the embedded beverage machine → first rear air vent 1011 → fan assembly 400 → front air outlet 1021. This further enhances the heat dissipation effect. For example, the housing assembly 100 may also include a front air vent 1022 located on the front wall 102 of the housing, which connects the inner cavity 103 to the outside. Since the air temperature at the front of the embedded beverage machine is relatively lower and is almost unobstructed, the front air vent 1022 can provide better cooling.

[0043] like Figure 3 As shown, exemplarily, the first rear air vent 1011 is located on the upper part of the rear wall 101 of the housing, and the second rear air vent is located on the lower part of the rear wall 101 of the housing. Since hot air has a lower density, most of the hot air will accumulate in the upper rear area of ​​the embedded beverage machine. The first rear air vent 1011 can preferentially draw this warmer air to the front of the embedded beverage machine, improving heat dissipation.

[0044] For example, the rear wall 101 of the housing has a recessed portion 104 that is recessed into the inner cavity 103. The recessed portion 104 has a recessed rear wall facing rearward, and the second rear air vent 1012 is disposed on the recessed rear wall of the recessed portion 104. In some usage scenarios, the rear wall 101 of the housing may be placed against the inner wall of the space accommodating the embedded beverage machine. In this case, the recessed portion 104 can at least form an airflow passage between the rear of the embedded beverage machine and the inner wall of the space, avoiding a situation where the heat dissipation component cannot dissipate heat at all while the fan assembly 400 cannot draw air away from the heat dissipation component.

[0045] In some exemplary embodiments, the first rear air outlet is arranged outside the recess 104. Since the rear wall 101 of the embedded beverage machine is usually not arranged close to the inner wall of the space, arranging the first rear air outlet outside the recess 104 can draw air from a larger range and improve the heat dissipation efficiency. In other embodiments, the first rear air outlet 1011 is arranged on the side wall of the recess 104. This can avoid the heat dissipation failure in the case that the rear wall 101 of the embedded beverage machine is arranged close to the inner wall of the space. In some embodiments, part of the first rear air outlet 1011 is arranged outside the recess 104 and the other part is arranged on the side wall of the recess 104. In this way, the first rear air outlet 1011 can have a large enough air inlet area while adapting to various installation modes.

[0046] Exemplarily, the embedded beverage machine comprises a waterway connector 800 arranged on the recessed rear wall. The embedded beverage machine is usually connected with a water supply pipe, and in the case that the embedded beverage machine comprises a water purification function, some embedded beverage machines are further provided with a concentrated water discharge port, so as to discharge the concentrated water generated by the nanofiltration filter element or the reverse osmosis filter element (which will be described in detail below) to the outside. The waterway connector 800 arranged in the recess 104 can avoid the rear wall 101 of the embedded beverage machine being too close to the inner wall of the space, which can cause the pipe to be excessively bent and affect use. In some embodiments, an electrical connector 800 can also be arranged on the recessed rear wall. The electrical connector 800 can comprise a socket adapted to the pin-shaped plug, or can be a plug itself connected with a power cord, and the power cord enters the inner cavity 103 from the opening of the recessed rear wall. In this way, the excessive bending of the power cord can also be avoided.

[0047] In combination with reference to Figure 2 and Figure 5 Exemplarily, the embedded beverage machine further comprises a first filter element assembly 510 and a second filter element assembly 520. For each of the first filter element assembly 510 and the second filter element assembly 520, a detachable filter element and a filter element seat can be included. For the filter element, the first filter element assembly 510 and the second filter element assembly 520 can respectively comprise a front filter element and a central filter element, or respectively comprise a central filter element and a rear filter element. The central filter element plays a major filtering role. Taking the first filter element assembly 510 and the second filter element assembly 520 as the front filter element and the central filter element as examples, the front filter element can be a composite filter element, which is arranged in front of the central filter element and is used to preliminarily filter the water entering the central filter element to prolong the service life of the central filter element. The central filter element can comprise a reverse osmosis filter element, an ultrafiltration filter element, a nanofiltration filter element, or a filter element composed of any two or more of them. For the reverse osmosis filter element and the nanofiltration filter element, the water needs to be pressurized before entering the filter element, and in this case, the embedded beverage machine can further comprise a booster pump. Thus, the embedded beverage machine can provide high-quality purified water for the user.

[0048] The inner cavity 103 can include a main body compartment 1031 in which the heating assembly, the heat dissipation assembly, and the fan assembly 400 are accommodated. As described above, the water taking nozzle 300 is arranged at the front of the main body compartment 1031. Water can splash out when taking water, or water droplets can fall after taking water. The main body compartment 1031 can prevent water from entering the heating assembly, the heat dissipation assembly, and the fan assembly 400. The inner cavity 103 can further include a first filter cartridge compartment 1032 in which the first filter cartridge assembly 510 is accommodated, and a second filter cartridge compartment 1033 in which the second filter cartridge assembly 520 is accommodated. In embodiments in which the first filter cartridge assembly 510 and the second filter cartridge assembly 520 include filter cartridge seats and filter cartridges that are replaceable, the user can need to replace the filter cartridges during routine maintenance. Since the filter cartridges can have water remaining when they are removed, the water can flow into the inner cavity 103 when the user replaces the filter cartridges, 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 the elements in the main body compartment 1031. As shown, at least the lower half can be isolated, thereby effectively preventing water from flowing to the area of the electrical elements.

[0049] The front air inlet 1022 is in communication between the first filter cartridge compartment 1032 and the outside, and the first filter cartridge compartment 1032 is in communication with the main body compartment 1031. The front air outlet 1021 is in communication between the second filter cartridge compartment 1033 and the outside, and the second filter cartridge compartment 1033 is in communication with the main body compartment 1031. In one aspect, the air flow drawn from the rear of the embedded beverage machine can be buffered in the second filter cartridge compartment 1033, and directed from the fan air outlet 420 located above to the front air outlet 1021 located below, which can further prevent hot air with a relatively high temperature from blowing onto the user. In another aspect, by using the first filter cartridge compartment 1032 and the second filter cartridge compartment 1033 as air flow channels, there is no need to provide additional guide channels in the inner cavity 103, which can simplify the structure of the inner cavity 103.

[0050] The central filter cartridge can include a reverse osmosis filter cartridge, the pore size of which is one millionth of a hair (0.1 nanometer), and the bacteria and viruses that cannot be seen by the naked eye are 10 times larger than that. Therefore, only water molecules and part of beneficial mineral ions to the human body can pass through, and other impurities and heavy metals are discharged from the concentrated water outlet, providing high-quality clean water for the user. The second filter cartridge assembly 520 can include a reverse osmosis filter cartridge as a central filter cartridge, which can increase the temperature of the reverse osmosis filter cartridge when the fan assembly 400 draws hot air into the second filter cartridge compartment 1033, thereby increasing the water flow rate of the reverse osmosis filter cartridge to a certain extent.

[0051] Referring back to Figure 1For example, the front wall 102 of the shell has a water taking cavity 210 recessed towards the inner cavity 103, and the top of the water taking cavity 210 is provided with a water taking nozzle 300. The water taking nozzle 300 can provide normal temperature water, hot water or cold water for the user. In some embodiments, a water receiving box 240 can also be provided in the water taking cavity 210, and the water remaining in the water taking nozzle 300 when not taking water can drip into the water receiving box 240. For a better understanding, reference is made to Figure 2 and Figure 6 The water taking cavity 210 includes a cavity top wall 211, a cavity bottom wall 212 and a cavity back wall 213, the cavity top wall 211 and the cavity bottom wall 212 are opposite to each other in the vertical direction, and the cavity back wall 213 is connected between the cavity top wall 211 and the cavity bottom wall 212. The water taking cavity 210 also includes a first cavity side wall 214 and a second cavity side wall 215, the first cavity side wall 214 and the second cavity side wall 215 are connected between the cavity top wall 211 and the cavity bottom wall 212, and are respectively located on both sides of the cavity back wall 213. In some embodiments, the water taking cavity 210 can serve as a space for accommodating a user's water taking container, and the user can not need to hold the water taking container all the time during the water taking process. In addition, the water taking cavity 210 recessed towards the inner cavity 103 can make the embedded water dispenser have no structure protruding from the front wall 102 of the shell. In this way, during the use of the user, there will be no situation of bumping into the protruding part and being injured or damaging the embedded water dispenser. The front air outlet 1021 and the front air inlet 1022 are respectively arranged on the first cavity side wall 214 and the second cavity side wall 215. In this way, the air blown at least from the front of the embedded beverage dispenser will not be directly blown towards the user, but will be blown at least partially laterally, improving the user experience.

[0052] Exemplarily, the first cavity side wall 214 comprises a first cavity straight wall 2141 and a first cavity inclined wall 2142, both of which are connected between the cavity top wall 211 and the cavity bottom wall 212, and the first cavity inclined wall 2142 is connected between the first cavity straight wall 2141 and the cavity back wall 213, and the first cavity inclined wall 2142 is inclined to the outside of the water taking cavity 210 away from the inner cavity 103. The second cavity side wall 215 comprises a second cavity straight wall 2151 and a second cavity inclined wall 2152, both of which are connected between the cavity top wall 211 and the cavity bottom wall 212, and the second cavity inclined wall 2152 is connected between the second cavity straight wall 2151 and the cavity back wall 213, and the second cavity inclined wall 2152 is inclined to the outside of the water taking cavity 210 away from the inner cavity 103. Thus, the first cavity inclined wall 2142 and the second cavity inclined wall 2152 form an obtuse angle with the cavity back wall 213, which is easy to clean. The first cavity straight wall 2141 and the first cavity inclined wall 2142, and the second cavity straight wall 2151 and the second cavity inclined wall 2152 also form an obtuse angle which is easy to clean. In some embodiments, the water taking cavity 210 can be integrally formed on the shell front wall 102, and the above structure can avoid excessive bending angle at the bending part, and ensure the strength of the shell front wall 102 and the water taking cavity 210. In other embodiments, the water taking cavity 210 and the shell front wall 102 are not integrally formed. In these embodiments, the shell front wall 102 has an outer side plate 250, and the outer side plate 250 comprises an outer side plate opening 251 which exposes the water taking cavity 210. The outer side plate opening 251 is usually slightly smaller than the front opening of the water taking cavity 210, so that it is not necessary to match the size of the water taking cavity 210 completely, which reduces the precision requirement of processing. And compared with the embodiment in which the outer side plate opening 251 is larger to expose the edge of the water taking cavity 210, it is more beautiful. In this case, the first cavity straight wall 2141 and the second cavity straight wall 2151 are connected between the inner surface of the outer side plate 250 and the first cavity inclined wall 2142 and the second cavity inclined wall 2152, and can form a right angle with the inner surface of the outer side plate 250. Compared with the embodiment in which the first cavity inclined wall 2142 and the second cavity inclined wall 2152 directly extend to the inner surface of the outer side plate 250 to form an acute angle, it is more convenient to clean.

[0053] The first cavity straight wall 2141 and the second cavity straight wall 2151 are oppositely arranged along the lateral direction, and the front air outlet 1021 and the front air inlet 1022 are arranged on the first cavity straight wall 2141 and the second cavity straight wall 2151 respectively. Thus, the front air outlet 1021 and the front air inlet 1022 can further guide the airflow, so as to avoid the user from perceiving the airflow, thereby improving the user experience.

[0054] In combination with reference Figures 6 to 8Exemplarily, the housing assembly 100 includes a rear housing 110 and a front door 120. The front door 120 is openable and closable on the rear housing 110, and the front door 120 and the rear housing 110 together form an inner cavity 103. 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. In the open state, the inner cavity 103 can be exposed. The figure shows only one front door 120, but in embodiments not shown, there may be more than one front door, for example, a double-door structure. The openable front door facilitates routine maintenance and upkeep of the embedded beverage machine, eliminating the need for the user to remove or pull the embedded beverage machine from its housing, reducing workload, and decreasing the possibility of tipping over due to instability when the embedded beverage machine is pulled out of its housing.

[0055] like Figure 6 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.

[0056] The front door 120 may include an inner liner 260 and the aforementioned outer liner 250. The water intake cavity 210 is formed by the inner liner 260 recessed into the inner cavity 103. The outer liner 250 covers the outer side of the inner liner 260. The water intake cavity 210 is formed by the inner liner 260 recessed into the inner cavity 103. The structure of the water intake cavity 210 is relatively complex. In some embodiments, the inner liner 260 is formed of a thin metal sheet, and the water intake cavity 210 thereon can be formed by sheet metal processing or stamping, or it can be formed by welding multiple independent thin metal sheets. In some embodiments, the inner liner 260 is injection molded. The outer liner 250 can be integrally formed, for example, a single piece of glass, ceramic, or stainless steel plate cut to the required shape. Thus, the front door 120 can be assembled from the outer liner 250 and the inner liner 260. The outer liner 250 can be made of different materials than the inner liner 260, and the production process is relatively simple and cost-effective. The outer panel 250 can be made of different materials than the inner lining panel 260, and the production process is relatively simple and cost-effective. The outer panel 250 is aesthetically pleasing, and its surface does not have gaps that easily accumulate dirt, making it easy to clean.

[0057] Exemplarily, the projections of the first cavity straight wall 2141 and the second cavity straight wall 2151 on the plane where the outer side plate 250 is located completely fall into the outer side plate 250. Thus, when the front door 120 is in the closed state, the user can only see the integrated outer side plate 250 in the front view. The outer side plate 250, which is easy to clean and aesthetically pleasing, can to some extent shield the gap formed by the embedded water dispenser and the space containing it, reduce the possibility of dust entering, and facilitate cleaning.

[0058] Exemplarily, the blocking cover 1023 covers the front air outlet 1021 on the inner side of the shell front wall 102, and the blocking cover 1023 and the inner surface of the shell front wall 102 enclose a buffer cavity. The blocking cover 1023 is provided with an air vent penetrating in a first direction, and the front air outlet 1021 penetrates in a second direction. The angle between the first direction and the extension direction of the fan air outlet 420 is smaller than the angle between the second direction and the extension direction of the fan air outlet 420. Figure 8 In the embodiment shown, the first direction and the second direction are perpendicular, so that the air vent of the blocking cover 1023 is directly opposite the fan air outlet 420 facing forward, and the front air outlet 1021 faces the left side. In an embodiment not shown, the air vent can not be directly opposite the fan air outlet 420, but can be generally aligned with the direction of the fan air outlet 420, so that a smooth airflow path can be formed therebetween. The front air outlet 1021 and the air vent have a large bending, which can further guide the hot air and prevent it from being directly blown to the user. Exemplarily, the air vent can be provided in a lattice shape, which can not only provide a blocking function to prevent foreign matter from entering, but also can have a large air flow area to meet the heat dissipation requirement. In comparison, since the air inlet can be provided through the gap between the embedded beverage dispenser and the containing space, and the air inlet provided at other positions of the shell assembly 100, the air inlet on the front door 120 of the embodiment shown in the figure can be formed by a plurality of small holes formed on the first cavity straight wall 2141, only providing part of the air inlet, and there is no need to provide the blocking cover 1023 to guide the airflow.
