Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of water treatment, in particular, to an embedded water supply machine. BACKGROUND

[0002] With the development of the times, people's requirements for the quality of drinking water are getting higher and higher. Water supply machines have been recognized and purchased by most people. The water supply machine can have the functions of purification, heating, etc., and can provide high-quality water sources for users.

[0003] Embedded water supply machines have appeared on the market. Such water supply machines can be arranged in a sideboard, and users can conveniently take water while eating. Some embedded water supply machines are provided with protruding faucets, and users can take water at the faucets. Some embedded water supply machines are provided with door panels, and users can take water after opening the door panels. There are consumables inside the embedded water supply machine, which need to be opened regularly for maintenance. Some embedded water supply machines on the market provide sliding rails, which can be pulled out from the inside of the sideboard, etc., so as to open the side of the embedded water supply machine for maintenance.

[0004] However, with the increasing functions of the embedded water supply machine, its weight is also getting heavier. Pulling out the embedded water supply machine from the sideboard may cause the sideboard to tip over due to unstable center of gravity. Therefore, there is an urgent need for a solution that can open the shell of the embedded water supply machine from the front for maintenance. CONTENT OF THE INVENTION

[0005] In order to at least partially solve the problems existing in the prior art, some embodiments of the present application provide an embedded water supply machine, which comprises: a rear shell; a front door, which is arranged in the rear shell in a hinged manner, and the front door and the rear shell jointly form an inner cavity; a water supply assembly, which is arranged in the inner cavity; and a water taking nozzle, which is connected to the water supply assembly, wherein the front door is provided with a water taking opening, and the water taking opening exposes the water taking nozzle when the front door is in a closed state. Through the front door structure, the user can conveniently open the front door to regularly maintain the inside of the embedded water supply machine, without the need to pull out the relatively heavy embedded water supply machine from the space where it is arranged, effectively preventing the risk of unstable center of gravity of the drawer-type embedded water supply machine during maintenance. Moreover, when the front door is in a closed state, the user can also perform water taking operation, and the user experience is good.

[0006] Exemplarily, the front door is pivotally connected to the rear shell about a pivot axis extending in a vertical direction. The lateral direction opening door usually does not interfere with the user's operation, and does not require additional retaining structure, which is cost-effective and convenient.

[0007] Exemplarily, the outer surface of the front door is recessed to form a water taking cavity towards the inner cavity, the water taking cavity comprises a top wall, a bottom wall and a rear wall connected between the top wall and the bottom wall, the top wall and the bottom wall are opposite to each other in the vertical direction, and at least a part of the water taking opening is arranged on the top wall, the water taking opening on the top wall exposes the outlet portion of the water taking nozzle. The water taking cavity can facilitate the user to place a water taking container, and the water taking cavity recessed towards the inner cavity can make the embedded water supply machine not have a structure protruding from the front surface. In this way, during use of the user, there is no possibility of injury or damage to the embedded water supply machine due to bumping into the protruding part.

[0008] Exemplarily, a base is arranged in the inner cavity, the water taking nozzle is fixed on the base, and the bottom surface of the base exposes the outlet portion of the water taking nozzle, and when the front door is in the closed position, the top wall of the water taking cavity abuts against the bottom surface of the base. The base can be at least partially provided with an elastic material, such as a sealing ring. When the top wall of the water taking cavity abuts against the bottom surface of the base, the elastic material can form a seal therebetween, thereby preventing water from seeping into the inner cavity from the water taking opening during water taking.

[0009] Exemplarily, the outlet portion of the water taking nozzle protrudes from the bottom surface of the base, the water taking opening extends from the top wall to the top of the rear wall, and the projection of the outlet portion of the water taking nozzle on the rear wall of the water taking cavity falls into the water taking opening. In this way, during water taking, water is guided by the outlet portion and flows vertically downward. On the other hand, the protruding outlet portion is easier to clean and prevents dirt accumulation. The outlet portion of the water taking nozzle can also enter the water taking cavity when the front door is closed.

[0010] Exemplarily, the front door comprises: an inner lining plate, the water taking cavity is recessed towards the inner cavity by the inner lining plate; and an outer side plate, the outer side plate covers the outer side of the inner lining plate and comprises an outer side plate opening, the outer side plate opening exposes the water taking cavity. In this way, the front door can be assembled by the outer side plate and the inner lining plate, the outer side plate and the inner lining plate can have different materials, and the production process is relatively simple and the cost is relatively low. The integrally formed outer side plate is more beautiful and the surface does not have gaps that are easy to accumulate dirt, which is easy to clean.

[0011] Exemplarily, under the condition that the front door is in the closed state, the projection of the inner lining plate and the rear shell on the plane where the outer side plate is located falls completely into the outer contour of the outer side plate. While being beautiful, the outer side plate which is easy to clean can to some extent shield the gap formed by the embedded water supply machine and the space (such as a side cabinet) containing it, reduce the possibility of dust entering, and facilitate cleaning.

[0012] Exemplarily, the front door further comprises a water receiving box, which is arranged at the bottom of the water taking cavity and located at the side of the outer side plate close to the inner cavity. After taking water, the water remaining in the water taking nozzle can drip into the water receiving box. Alternatively, when the water is accidentally spilled, it can also be first received by the water receiving box. Arranging the water receiving box at the side of the outer side plate close to the inner cavity, the water receiving box is almost invisible from the front, which is more beautiful. At the same time, the water receiving box is blocked by the outer side plate and can only be taken out under correct operation, effectively preventing the water receiving box from being accidentally dropped or the spilled water.

[0013] Exemplarily, the outer side plate is made of glass. The outer side plate is provided with a display assembly and / or a touch control assembly at the rear part, and the glass material of the outer side plate can enable the display assembly to display through it, and the touch control assembly can also receive touch control signals through the glass.

[0014] Exemplarily, the water taking cavity further comprises a first side wall and a second side wall connected between the top wall and the bottom wall, the first side wall and the second side wall are respectively located at the two sides of the rear wall, and the distance between the edges of the first side wall and the second side wall close to the inner cavity is smaller than the distance between the edges of the first side wall and the second side wall away from the inner cavity, so that the width of the part of the water taking cavity away from the inner cavity in the lateral direction is greater than the width of the part of the water taking cavity close to the inner cavity in the lateral direction. This not only looks more beautiful, but also avoids sharp right angles or acute angles in the area that is easily contaminated, thus reducing the dead angle that is not easy to clean.

[0015] Exemplarily, the first side wall comprises a first straight wall and a first inclined wall, both connected between the top wall and the bottom wall, and the first inclined wall is connected between the first straight wall and the rear wall, the first inclined wall inclines away from the inner cavity to the outside of the water taking cavity, the second side wall comprises a second straight wall and a second inclined wall, both connected between the top wall and the bottom wall, and the second inclined wall is connected between the second straight wall and the rear wall, the second inclined wall inclines away from the inner cavity to the outside of the water taking cavity, the first straight wall and the second straight wall are oppositely arranged along the lateral direction, and at least one of the first straight wall and the second straight wall is provided with a ventilation opening in communication with the inner cavity. Compared with the embodiment in which the first inclined wall and the second inclined wall directly extend to the inner surface of the outer side plate to form an acute angle, it is more convenient to clean. Arranging the ventilation opening on the first straight wall or the second straight wall can make the blown hot air face the lateral direction, so as not to directly blow to the user, thereby improving the user experience.

[0016] Exemplarily, the water supply assembly comprises a first filter element assembly and a second filter element assembly, which are arranged in the inner cavity and respectively located at the two sides of the rear wall. Arranging the first filter element assembly and the second filter element assembly respectively at the two sides of the rear wall, the first inclined wall and the second inclined wall can each form a clearance for the first filter element assembly and the second filter element assembly, so that the space utilization of the embedded water supply machine is more reasonable.

[0017] Exemplarily, the embedded water supply machine further comprises an ice making assembly arranged in the inner cavity, and the front door further comprises an ice receiving opening, and the ice receiving opening is communicated with an ice outlet of the ice making assembly when the front door is in the closed state. Thus, the embedded water supply machine has more functions, and the ice cubes can be taken without opening the front door, and the user experience is good.

[0018] Exemplarily, the water supply assembly comprises a filter element assembly. Thus, clean water can be provided for the user.

DETAILED DESCRIPTION

[0029] 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.

[0030] 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.

[0031] The embodiments of the present application provide an embedded water supply machine. The embedded water supply machine according to the embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0032] Figure 1 An embedded water supply machine according to an exemplary embodiment of the present application is shown. As described above, the embedded water supply machine can be arranged in a containing space of a sideboard, for example. For the convenience of understanding, the face of the embedded water supply machine facing the user is considered as the front face, and the face facing away from the user is considered as the back face, and the left and right directions are the side faces of the embedded water supply machine.

[0033] The embedded water dispenser can include a rear shell 100 and a front door 200. The rear shell 100 can be made of plastic or metal. In the embodiment shown in the figure, the rear shell 100 can be made of sheet metal, which has high strength and low production cost. The embedded water dispenser can include a water outlet 300, which is used to provide water to the user during the water taking operation. The embedded water dispenser shown in the figure can have a water taking cavity 210, in which the user can place a water taking container, so that the user does not need to hold the water taking container during the water taking operation. In this case, the water outlet 300 can be arranged in the water taking cavity 210. In an embodiment not shown, the embedded water dispenser can also include a support table protruding from the front surface of the embedded water dispenser, on which the water taking container can be placed for the water taking operation. In this case, the water outlet can protrude from the front surface of the embedded water dispenser.

[0034] Reference Figure 2 The front door 200 is arranged on the rear shell 100 in a pivotable or slidable manner, and the front door 200 and the rear shell 100 form an inner cavity 400. In an embodiment, the front door 200 is pivotally connected to the rear shell 100. In another embodiment, the front door 200 is slidably connected to the rear shell 100. When the front door 200 is opened, the inner cavity 400 is exposed. In the embodiment shown in the figure, the front door 200 is the only one, and in an embodiment not shown, the front door 200 can be more than one, for example, a double door structure. The embedded water dispenser further includes a water supply assembly arranged in the inner cavity 400. The water supply assembly includes, but is not limited to, a water purification assembly, a heating assembly, and a refrigeration assembly. The water outlet 300 can be connected to the water supply assembly, so as to receive normal temperature purified water, hot water or cold water provided by the water supply assembly.

[0035] The front door 200 can be provided with a water taking opening 220, which exposes the water outlet 300 when the front door 200 is in a closed state. In this way, the user can take water without opening the front door 200 in daily use, which is simple and convenient to operate. When the front door 200 is opened, the user can maintain the water supply assembly in the inner cavity 400. In a specific embodiment, the water supply assembly can include a filter element, which can be maintained and replaced by the user. In another embodiment, the water supply assembly includes a water tank, which can be cleaned by the user. In yet another embodiment, the water supply assembly can be provided with a heating tank and a magnesium rod, which can be replaced by the user.

[0036] In summary, through the front opening structure, the user can more conveniently open the front door 200 to perform routine maintenance on the interior of the embedded water dispenser without having to extract the relatively heavy embedded water dispenser from the space in which it is disposed, effectively preventing the risk of instability of the center of gravity of the drawer-type embedded water dispenser during maintenance. And when the front door 200 is in the closed state, the user can also perform water taking operations, and the user experience is good.

[0037] In some embodiments, the front door 200 is pivoted open about a horizontally disposed pivot axis. In one embodiment, the lower edge of the front door 200 can be pivoted to a height close to the upper edge of the front door 200, or even to a height higher than the upper edge of the front door 200. In this embodiment, the user can need to lift the front door 200, or the embedded water dispenser can be provided with a structure that allows the front door 200 to be maintained in an open state. In another embodiment, the upper edge of the front door 200 can be pivoted to a height close to the lower edge of the front door 200, or to a height lower than the lower edge of the front door 200. For these embodiments of the embedded water dispenser, the front door 200 can not be placed in a vertical state, causing the user to be obstructed by the front door 200 during maintenance. Exemplarily, the front door 200 is pivotally connected to the rear shell 100 about a pivot axis extending in the vertical direction. As shown, the rear shell 100 can be provided with a first pivot hole 110, and the front door 200 is provided with a second pivot hole 230, the first pivot hole 110 and the second pivot hole 230 are concentrically disposed and installed with a rivet or a screw. In this way, the front door 200 can be pivoted about the pivot axis. The lateral direction opening of the door generally does not interfere with the user's operation, and no additional retaining structure is required, combining cost and convenience. Figure 3

[0038] As shown in FIG. 1, the embedded water dispenser can be provided with a front door 200 pivotally connected to the rear shell 100. The front door 200 can be provided with a front door opening 210, and the rear shell 100 can be provided with a rear shell opening 120. The front door opening 210 and the rear shell opening 120 can be aligned with each other in the vertical direction. The front door 200 can be provided with a front door handle 220, and the rear shell 100 can be provided with a rear shell handle 130. The front door handle 220 and the rear shell handle 130 can be aligned with each other in the vertical direction. The front door 200 can be provided with a front door door frame 240, and the rear shell 100 can be provided with a rear shell door frame 140. The front door door frame 240 and the rear shell door frame 140 can be aligned with each other in the vertical direction. Figure 4 ​As shown, the outer surface of the front door 200 can be recessed to form a water taking cavity 210 towards the inner cavity 400. Alternatively, the water taking cavity can be formed by sheet metal processing. Alternatively, the water taking cavity can be formed by splicing multiple parts. Alternatively, the water taking cavity can be a part of the front door in structure. As mentioned above, the water taking cavity 210 can facilitate the user to place a water taking container, and the water taking cavity 210 recessed towards the inner cavity 400 can make the embedded water dispenser not have a structure protruding from the front surface. In this way, during 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 water taking cavity 210 includes a top wall 211, a bottom wall 212 (not shown due to the blocking of the water receiving box), and a rear wall 213 connected between the top wall 211 and the bottom wall 212, the top wall 211 and the bottom wall 212 are opposite to each other in the vertical direction, and at least part of the water taking opening 220 is arranged on the top wall 211, and the water taking opening 220 on the top wall 211 exposes the outlet part of the water taking nozzle 300. In other words, the top wall 211 is provided with the water taking opening 220, so that the lower part of the water taking nozzle 300 is not blocked by the top wall 211. As shown, the size of the water taking opening 220 is slightly larger than the outlet part of the water taking nozzle 300, and the edge of the water taking opening 220 can avoid the outlet part during the rotation of the front door 200 around the pivot shaft to the closed state. The size of the water taking opening 220 is only slightly larger than the size of the outlet part, so that when the front door 200 is in the closed state, a larger gap is not formed around the water taking opening 220, which can avoid the accumulation of dirt and make the water taking cavity 210 more beautiful.

[0039] In the embodiment shown in the figure, the water taking nozzle 300 can only have one, and the corresponding water taking opening 220 is also one. In the embodiment not shown, the water taking nozzle can have multiple, and multiple water taking nozzles can provide different water such as hot water and cold water, and the water taking opening can be multiple corresponding to the number of water taking nozzles, or it can be one, and multiple water taking nozzles can be extended from this water taking opening. The water taking nozzle can be symmetrically arranged about the central axis of the embedded water dispenser, or it can be asymmetrically arranged. The present application also does not exclude the embodiment of arranging multiple water taking openings and multiple water taking nozzles, part of the water taking openings corresponding to multiple water taking nozzles, and part of the water taking openings corresponding to single water taking nozzles.

[0040] To simplify the manufacture of the rear shell 100, the water outlet 300 is usually a structure independent of the rear shell 100. This facilitates the assembly of the embedded water supply machine, and allows the rear shell 100 and the water outlet 300 to be made of different materials and processes, improving product yield and reducing costs. Therefore, the water outlet 300 needs to be mounted to the rear shell 100. Illustratively, a base 410 can be arranged in the inner cavity 400, and the water outlet 300 is fixed to the base 410. The base 410 can be integrally formed with the rear shell 100, or can be a separate part that provides a fixing function between the water outlet 300 and the rear shell 100. In an embodiment not shown, the base can extend below the water outlet. In another embodiment not shown, the base can only fix the water outlet from the side. In the embodiment in which the base 410 extends below the water outlet, the bottom surface of the base 410 exposes the outlet portion of the water outlet 300. That is, the bottom of the base 410 does not block the outlet portion of the water outlet 300, so that the water flowing out of the outlet portion can flow directly downward. The outlet portion can be embedded in the base 410, flush with the bottom surface of the base 410, or protrude from the bottom surface. When the front door 200 is in the closed position, the top wall 211 of the water taking cavity 210 abuts against the bottom surface of the base 410. In some embodiments, the base 410 can be at least partially provided with an elastic material, such as a sealing ring. When the top wall 211 of the water taking cavity 210 abuts against the bottom surface of the base 410, the elastic material can form a seal therebetween, thereby preventing water from seeping into the inner cavity 400 from the water taking opening 220 during water taking.

[0041] For embodiments in which the outlet portion of the water outlet 300 does not protrude from the bottom surface of the base 410, if there is vibration during water taking, or there is dirt between the water outlet 300 and the bottom surface of the base 410, or the outlet portion is damaged, it is likely that water will flow along the inner wall of the water taking cavity 210 during water taking. To avoid such situations, illustratively, the outlet portion of the water outlet 300 can protrude from the bottom surface of the base 410. In this way, during water taking, the water will be guided by the outlet portion and flow vertically downward. On the other hand, the protruding outlet portion is easier to clean and prevents dirt accumulation.

[0042] Since the outlet portion of the water outlet 300 protrudes from the bottom surface of the base 410, the water taking opening 220 extends from the top wall 211 to the top of the rear wall 213, and the projection of the outlet portion of the water outlet 300 on the rear wall 213 of the water taking cavity 210 falls within the water taking opening 220. Thus, the outlet portion of the water outlet 300 can enter the water taking cavity 210 when the front door 200 is closed.

[0043] For reference Figure 2 and Figure 5For example, the front door 200 includes an inner lining plate 260, and the water taking cavity 210 is recessed from the inner lining plate 260 to the inner cavity 400. The structure of the water taking cavity 210 is relatively complex, and in some embodiments, the inner lining plate 260 is formed by a metal sheet, and the water taking cavity 210 on the inner lining plate 260 can be formed by sheet metal or stamping, or can be formed by welding a plurality of independent metal sheets. In some embodiments, the inner lining plate 260 is formed by injection molding. The front door 200 can further include an outer side plate 250 covering the outer side of the inner lining plate 260, and the outer side plate 250 includes an outer side plate opening 251 exposing the water taking cavity 210. The outer side plate 250 can be integrally formed, for example, a whole piece of glass, ceramic or stainless steel plate cut into a desired shape. Thus, the front door 200 can be assembled by the outer side plate 250 and the inner lining plate 260, the outer side plate 250 can have a different material from the inner lining plate 260, and the production process is relatively simple and low in cost. The integrally formed outer side plate 250 is more beautiful, and the surface does not have gaps that are easy to accumulate dirt, and is easy to clean.

[0044] For example, when the front door 200 is in a closed state, the projections of the inner lining plate 260 and the rear shell 100 on the plane of the outer side plate 250 completely fall within the outer contour of the outer side plate 250. In this way, the user can only see the outer side plate 250 in the front, and the easy-to-clean outer side plate 250 can to some extent shield the gap formed by the embedded water supply machine and the space containing it (for example, a sideboard), reduce the possibility of dust entering, and facilitate cleaning.

[0045] For example, the front door 200 can further include a water receiving box 240, which can be arranged at the bottom of the water taking cavity 210, and the water receiving box 240 is located on the side of the outer side plate 250 close to the inner cavity 400. As shown in Figure 1 The water receiving box 240 can be located directly below the water taking nozzle 300, and after taking water, the water remaining in the water taking nozzle 300 can drip into the water receiving box 240. Or when the water accidentally spills, it can also be first received by the water receiving box 240. The water receiving box 240 is arranged on the side of the outer side plate 250 close to the inner cavity 400, and almost invisible in the front, more beautiful. At the same time, the water receiving box 240 is blocked by the outer side plate 250, and can only be taken out under correct operation, effectively preventing the water receiving box 240 from accidentally falling or the water contained therein from spilling.

[0046] In one embodiment, the bottom of the inner plate 260 can form a receiving cavity with the outer plate 250, and the water receiving box 240 has a structure that fits the receiving cavity to be mounted to the receiving cavity. This makes the water receiving box 240 reliably mounted to the front door 200, and reduces the gap between the water receiving box 240 and the receiving cavity, avoiding dirt accumulation or water accumulation in the receiving cavity. The water receiving box 240 can include a box body 241 and a top cover 242, and the bottom wall 212 of the box body 241 is provided with a protrusion part protruding into the box cavity, which separates the top cover 242 from the bottom wall 212. In this way, the water receiving box 240 can have sufficient capacity to receive water. When the water receiving box 240 is removed, the top cover 242 can be removed first, and the water receiving box 240 can be removed through the protrusion part, which is relatively easy to operate. The top cover 242 is configured as a fence shape to allow water to flow in, preventing foreign matter from falling into the water receiving box 240.

[0047] Exemplarily, the outer plate 250 can be made of glass. It is not only beautiful, but also easy to clean. In some embodiments, the portion of the outer plate 250 close to the inner cavity 400 is provided with a display assembly and / or a touch control assembly, and the glass outer plate 250 can allow the display assembly to display through it, and the touch control assembly can also receive touch control signals through the glass.

[0048] Exemplarily, the water receiving cavity 210 further includes a first side wall 214 and a second side wall 215 connected between the top wall 211 and the bottom wall 212, and the first side wall 214 and the second side wall 215 are respectively located on both sides of the rear wall 213. The distance between the edges of the first side wall 214 and the second side wall 215 close to the inner cavity 400 is smaller than the distance between the edges of the first side wall 214 and the second side wall 215 away from the inner cavity 400, so that the width of the portion of the water receiving cavity 210 away from the inner cavity 400 in the lateral direction is greater than the width of the portion of the water receiving cavity 210 close to the inner cavity 400 in the lateral direction. The cross section of the water receiving cavity 210 is trumpet-shaped. This not only makes it more beautiful, but also avoids sharp right angles or acute angles in areas that are more susceptible to contamination, thereby reducing dead angles that are difficult to clean.

[0049] Exemplarily, the first side wall 214 includes a first straight wall 2141 and a first inclined wall 2142, both of which are connected between the top wall 211 and the bottom wall 212, and the first inclined wall 2142 is connected between the first straight wall 2141 and the back wall 213 and inclines away from the inner cavity 400 to the outside of the water taking cavity 210. The second side wall 215 includes a second straight wall 2151 and a second inclined wall 2152, both of which are connected between the top wall 211 and the bottom wall 212, and the second inclined wall 2152 is connected between the second straight wall 2151 and the back wall 213 and inclines away from the inner cavity 400 to the outside of the water taking cavity 210. The first straight wall 2141 and the second straight wall 2151 are oppositely arranged along the lateral direction. Thus, the first inclined wall 2142 and the second inclined wall 2152 form an obtuse angle with the back wall 213, which is easy to clean. The first straight wall 2141 and the first inclined wall 2142, and the second straight wall 2151 and the second inclined wall 2152 also form obtuse angles which are easy to clean. The outer side plate opening 251 is generally slightly smaller than the opening of the water taking cavity 210 away from the inner cavity 400, so that it is not necessary to completely match the size of the water taking cavity 210, thereby reducing 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 straight wall 2141 and the second straight wall 2151 are connected between the inner surface of the outer side plate 250 and the first inclined wall 2142 and the second 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 inclined wall 2142 and the second 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.

[0050] Exemplarily, at least one of the first straight wall 2141 and the second straight wall 2151 is provided with a ventilation opening 216 which communicates with the inner cavity 400. The ventilation opening 216 can blow out hot air, and by arranging the ventilation opening 216 on the first straight wall 2141 or the second straight wall 2151, the blown hot air can be directed towards the lateral direction and not directly towards the user, thereby improving the user experience. Figure 5 In the illustrated embodiment, the ventilation opening 216 can include an air inlet 2161 arranged on the left first straight wall 2141 and an air outlet 2162 arranged on the right second straight wall 2151. A buffer cavity 217 is arranged at the air outlet 2162 to buffer the incoming airflow and avoid directly blowing towards the user to affect the experience.

[0051] Referring back to Figure 2The water supply assembly includes a first filter element assembly 510 and a second filter element assembly 520. The first filter element assembly 510 and the second filter element assembly 520 are arranged in the inner cavity 400 and are located on two sides of the rear wall 213 respectively. 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 include a front filter element and a central filter element respectively, or include a central filter element and a rear filter element respectively. 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 respectively, the front filter element can be a composite filter element, which is located in front of the central filter element and is used to perform preliminary filtration on the water entering the central filter element to prolong the service life of the central filter element. The central filter element can include a reverse osmosis filter element, an ultrafiltration filter element, a nanofiltration filter element, or a filter element composed of any two or more of them. For the reverse osmosis filter element and the nanofiltration filter element, the water needs to be pressurized before entering the filter element, in which case the water supply assembly can also include a booster pump. Thus, the water supply assembly can provide high-quality purified water for the user. By arranging the first filter element assembly 510 and the second filter element assembly 520 on two sides of the rear wall 213 respectively, the first inclined wall 2142 and the second inclined wall 2152 can each form a clearance for the first filter element assembly 510 and the second filter element assembly 520, making the space utilization of the embedded water supply machine more reasonable.

[0052] Illustratively, the embedded water supply machine can also include an ice making assembly arranged in the inner cavity 400, and the front door 200 further includes an ice receiving opening 270, which is in communication with an ice outlet of the ice making assembly when the front door 200 is in the closed state. Thus, the embedded water supply machine has more functions, and ice cubes can be taken without opening the front door 200, providing a good user experience.
