Description

Technical Field

[0001] This utility model relates to the field of water treatment technology, specifically to an embedded pipeline machine. Background Technology

[0002] With the development of the times, people have increasingly higher requirements for drinking water quality, and simple water purifiers are no longer sufficient to meet their needs. Water dispensers can receive purified water from water purifiers and provide services such as hot and cold water, offering a wide range of functions and have been widely recognized and purchased. Water dispensers on the market include countertop and built-in models.

[0003] Built-in water dispensers are popular because they can be installed in spaces such as sideboards and cabinets, saving countertop space. Some built-in water dispensers can provide chilled water. Currently, some built-in water dispensers on the market use semiconductor refrigeration. Semiconductor refrigeration units are small, lightweight, and relatively quiet. Others use compressor refrigeration, which can provide even colder water, but is relatively bulky.

[0004] Regardless of the cooling method, cooling components require large heat sinks. Some cooling components also include fans. These fans are typically high-efficiency, low-noise axial fans, thus requiring sufficiently large exhaust vents on the casing to dissipate the heat generated by the chilled water. Large exhaust vents are not located at the front to avoid affecting the aesthetics of the embedded chiller. However, in the confined space of an embedded chiller, heat can gradually accumulate, reducing heat dissipation efficiency, leading to performance degradation, and even causing the chilled water to continue operating due to insufficient cooling temperature. Utility Model Content

[0005] To at least partially address the problems existing in the prior art, some embodiments of this utility model provide an embedded pipeline machine, comprising: a rear shell having a first rear shell sidewall facing a first lateral direction and a second rear shell sidewall facing a second lateral direction, the first and second lateral directions being opposite; a front panel, the front panel and the rear shell together forming an inner cavity, the front panel having a first side edge facing the first lateral direction and a second side edge facing the second lateral direction, an air inlet and an air outlet provided on the front panel, the air inlet being closer to the first side edge than the air outlet, at least a portion of the second rear shell sidewall being recessed inward relative to the second side edge toward the first lateral direction to form a hot air chamber; a cooling device disposed in the inner cavity, the cooling device including a cooling and heat dissipation component adjacent to the chamber wall of the hot air chamber, the cooling and heat dissipation component being used to transfer heat to the hot air chamber; and a hot air duct connecting the hot air chamber and the air outlet, the hot air duct being provided with a duct cooling fan. In the above technical solution, by setting up a hot air chamber, the external air outlet of the fan is not obstructed, thus ensuring the exhaust speed of the cooling and heat dissipation components' fans. By drawing some of the hot air from the hot air chamber to the front of the embedded pipeline machine through a hot air duct, the air temperature within the hot air chamber can be reduced, preventing the temperature of the hot air chamber from affecting the temperature of the cooling and heat dissipation components, further improving the efficiency of the cooling components. Positioning the air inlet away from the hot air chamber ensures that the air entering the embedded pipeline machine is at a lower temperature, also improving heat dissipation efficiency. In summary, through the above methods, the heat dissipation efficiency of the cooling components can be improved from multiple angles, avoiding performance degradation or problems such as insufficient chilled water temperature.

[0006] For example, the rear portion of the second rear shell sidewall is recessed relative to its front portion in a first lateral direction, forming a hot air chamber. The chamber wall of the hot air chamber is provided with a first heat dissipation vent and a second heat dissipation vent. The cooling and heat dissipation component is in fluid communication with the hot air chamber via the first heat dissipation vent, and the hot air duct is in fluid communication with the hot air chamber via the second heat dissipation vent. Compared to embodiments where the second rear shell sidewall is entirely recessed, the internal space of the embedded pipeline machine can be larger. Furthermore, sufficient space exists between the hot air chamber and the air outlet to accommodate the hot air duct, allowing the airflow from the hot air duct to reach the air outlet in a straight line, improving heat dissipation efficiency. The entire hot air duct can also be a straight structure that is easy to manufacture, simplifying the processing of the rear shell.

[0007] For example, the hot air chamber includes a first chamber wall facing a second lateral direction and a second chamber wall facing rearward. A first heat dissipation vent is disposed on the first chamber wall, and a second heat dissipation vent is disposed on the second chamber wall. Because the first chamber wall is relatively flat, the installation and fixing of the cooling and heat dissipation components are convenient, and it can fit snugly against the fan outlet, eliminating the need for additional air ducts and preventing airflow leakage back into the rear housing. The second heat dissipation vent can have a small gap from the first heat dissipation vent, thereby creating a lower air pressure in the area near the first heat dissipation vent, drawing some of the hotter air to the outlet. This configuration of the hot air chamber provides a sufficiently large volume, and the processing of the rear housing is simpler.

[0008] For example, the area of ​​the air outlet is smaller than the area of ​​the first heat dissipation vent. A smaller air outlet is not only more aesthetically pleasing but also does not damage the front panel structure. The cooling fan can be a centrifugal fan, which has a higher airflow rate, allowing for a larger air volume even with a smaller air outlet. This further reduces the size of the air outlet.

[0009] For example, the second heat dissipation vent is higher than the first heat dissipation vent. Since hot air has a lower density, the second heat dissipation vent can draw most of the hot air from the first heat dissipation vent to the air outlet, thereby effectively improving heat dissipation efficiency.

[0010] For example, a recessed water receiving cavity is provided on the front panel. This cavity has a first cavity sidewall located on the same side as the first rear shell sidewall and a second cavity sidewall located on the same side as the second rear shell sidewall. An air inlet is located on the first cavity sidewall, and an air outlet is located on the second cavity sidewall. The water receiving cavity serves as a space to accommodate the user's water container, allowing the user to dispense water without constantly holding the container. Furthermore, the recessed water receiving cavity eliminates any protruding structure from the front panel of the embedded water dispenser. This prevents users from bumping into protruding parts and injuring or damaging the embedded water dispenser. The air inlet is located on the first cavity sidewall, and the air outlet is located on the second cavity sidewall. This ensures that air blown from the front of the embedded beverage dispenser is not directly directed towards the user, but rather partially blown laterally, improving the user experience. The air inlet and outlet located on the sidewalls are also less likely to be blocked by objects placed on them.

[0011] For example, the second cavity sidewall has an inclined portion that slopes forward and in a second lateral direction, and the air outlet is disposed on the inclined portion, with the hot air duct perpendicular to the inclined portion. Thus, the airflow from the cooling fan in the duct is not obstructed and does not blow directly towards the user, ensuring airflow rate while avoiding impacting the user experience.

[0012] For example, an additional air inlet is provided on the side wall of the first rear housing. This allows for the intake of cool air not only through the main air dispenser's inlet but also through the gap between the embedded air dispenser and the housing space. The additional air inlet can have a larger intake area than the main air inlet, resulting in less resistance to the intake of cool air. The additional air inlet and the main air inlet are at least partially spaced apart and can converge only when they reach the cooling and heat dissipation components. This ensures that the airflow from the main air inlet and the airflow from the additional air inlet do not interfere with each other.

[0013] For example, at least a portion of the first rear shell sidewall is recessed inward relative to the first side edge toward the second lateral direction to form a cold air chamber, with an additional air inlet disposed on the chamber wall of the cold air chamber. The cold air chamber can be formed by the first rear shell sidewall being spaced apart from the inner wall of the receiving space, thereby preventing the inner wall of the receiving space from abutting against the additional air inlet, which would result in excessive airflow resistance. The cold air chamber can also buffer the hot air from the hot air chamber. In the cold air chamber, relatively hot air can mix with a sufficient amount of cold air for cooling, and the warmer air floats at the top, ensuring that the air temperature entering through the additional air inlet is relatively low.

[0014] For example, an additional air inlet is located on the lower part of the side wall of the first rear housing. This allows denser, cooler air to be drawn into the embedded pipeline unit, improving the heat dissipation efficiency of the cooling and heat dissipation components.

[0015] Exemplarily, the embedded water dispenser also includes one or more of the following components: a water tank located within the inner cavity and in front of the cooling device; an electronic control board located within the inner cavity and adjacent to the side wall of the first rear housing; a heating element assembly located in the front portion of the inner cavity and adjacent to the side wall of the first rear housing; a waterproof water pump located in the lower portion of the inner cavity; and a solenoid valve located in the lower portion of the inner cavity. The water tank can have a similar size to the cooling device in its frontal projection, and arranging them adjacently can improve space utilization. At least one waterproof water pump can be located below the water tank and the cooling device. This shortens the pipe length between the three components, facilitating the waterproof water pump to draw clean water from the water tank to replenish the cooling device. Even if the embedded water dispenser leaks, the waterproof water pump located at the bottom will not be damaged. Positioning the heating element assembly close to the front water inlet cavity shortens the pipes and prevents the hot water from cooling down after passing through the pipes. Shorter pipes also eliminate the need for insulation, reducing costs and assembly difficulty. Solenoid valves can be interspersed within the gaps of waterproof water pumps to improve the space utilization of embedded water dispensers. The inlet and outlet of embedded water dispensers are also usually located at the bottom, and can be connected to the solenoid valves with shorter pipes to control water supply and drainage.

[0026] In the following description, numerous details are provided to enable a thorough understanding of the present invention. However, those skilled in the art will appreciate that the following description merely illustrates preferred embodiments of the present invention, which may be practiced without one or more of these details. Furthermore, to avoid confusion with the present invention, some technical features well-known in the art have not been described in detail.

[0027] To fully understand the embodiments of this utility model, a detailed structure will be presented in the following description. Obviously, the implementation of the embodiments of this utility model is not limited to the specific details familiar to those skilled in the art. Preferred embodiments of this utility model are described in detail below; however, in addition to these detailed descriptions, this utility model may have other embodiments.

[0028] This utility model provides an embedded pipeline machine. The embedded pipeline machine according to an embodiment of this utility model will be described in detail below with reference to the accompanying drawings.

[0029] like Figure 1 As shown, the embedded pipeline machine may include a rear housing 100. In some embodiments, the rear housing 100 may be made of metal and manufactured by, for example, sheet metal processing. In other embodiments, the rear housing 100 may also be made of a material such as plastic and manufactured by injection molding. The rear housing 100 has a first rear housing sidewall 110 facing a first lateral direction (see reference). Figure 3 The first lateral direction and the second rear shell sidewall 120 face a second lateral direction, which are opposite to each other. Taking the embedded pipeline machine shown in the figure as an example, when viewed directly, the first lateral direction can be the left and the second lateral direction can be the right. In other embodiments, the first lateral direction can also be the right and the second lateral direction can be the left. For ease of description, the embodiment with the first lateral direction on the left will be described.

[0030] The embedded pipeline machine may also include a front panel 200, which may be made of the same material and process as the rear shell 100, or may be a composite of multiple different materials processed using corresponding techniques. In one specific embodiment, the front panel 200 may include an inner sheet metal liner and an outer glass panel. The front panel 200 and the rear shell 100 may be joined to form an inner cavity, which may serve as a space for accommodating internal components. In some embodiments, the inner cavity may have multiple non-communicating areas to separate water channels, electrical circuits, and internal airflow.

[0031] The embedded water dispenser includes a cooling unit 300 disposed within an internal cavity. As described above, the cooling unit 300 may include a thermoelectric cooling component, a compressor cooling component, or a combination of both. The cooling unit 300 may include a cooling heat dissipation component 310, which transfers heat from the water to be cooled during the cooling process. For a cooling unit 300 using a thermoelectric cooling component, the cooling heat dissipation component 310 may include a heat sink and a fan; for a cooling unit 300 using a compressor cooling component, the cooling heat dissipation component 310 may include a condenser coil and a fan. The fan can draw in air from the interior of the embedded water dispenser and through a connected air inlet 2111. The drawn-in or blown-out air passes through the heat sink or condenser coil and exits through the air outlet 2121 to the exterior of the embedded water dispenser.

[0032] The front panel 200 has a first side edge facing a first lateral direction and a second side edge facing a second lateral direction. An air inlet 2111 and an air outlet 2121 are provided on the front panel 200. The air inlet 2111 is closer to the first side edge than the air outlet 2121. At least a portion of the second rear shell sidewall 120 is recessed inward relative to the second side edge towards the first lateral direction to form a hot air chamber 400. Figure 2 As shown, a portion of the second rear shell sidewall 120 near the rear tapers inward toward a first lateral direction, forming a first compartment wall 410 and a second compartment wall 420. The first compartment wall 410 and the second compartment wall 420 are at right angles, allowing the hot air chamber 400 to be a cubic space. In some embodiments, the second rear shell sidewall 120 is entirely tapered inward toward the first lateral direction. The front panel 200 of the embedded pipeline machine is sized to match the opening of the receiving space 10, allowing the embedded pipeline machine to be mounted into the receiving space 10 (see...). Figure 3Afterwards, the second rear housing sidewall 120 may be spaced apart from the receiving space 10. In some other embodiments, the middle portion of the second rear housing sidewall 120 may also be recessed. The cooling and heat dissipation assembly 310 is adjacent to the wall of the hot air chamber 400. The cooling and heat dissipation assembly is used to transfer heat to the hot air chamber. Optionally, the cooling and heat dissipation assembly is a heat sink extending into the hot air chamber, which passively dissipates heat to the hot air chamber. Optionally, the wall of the hot air chamber 400 is made of a thermally conductive material, and the cooling and heat dissipation assembly transfers heat to the wall of the hot air chamber, and then to the hot air chamber. Optionally, the cooling and heat dissipation assembly may include a heat sink and a fan, the fan pumping air into the hot air chamber, the airflow path passing through the heat sink to dissipate heat from the heat sink. In summary, the hot air chamber 400 may be formed by the rear housing 100 of the embedded pipeline machine and the inner wall of the receiving space 10 that accommodates it. When the cooling and heat dissipation components are equipped with a fan, a larger fan outlet 2121 can be installed on the wall of the hot air chamber 400 to blow hot air into the hot air chamber 400. Since the fan outlet 2121 is unobstructed, the airflow can be relatively smooth, and the heat dissipation efficiency can be guaranteed to a certain extent.

[0033] During the cooling process, as the temperature of the cooling heat dissipation component 310 increases, the overall cooling efficiency tends to decrease. When the temperature difference between the chilled water and the cooling heat dissipation component 310 reaches a certain level, the temperature of the chilled water will not continue to decrease. To prevent hot air from accumulating in the hot air chamber 400, causing the temperature of the cooling heat dissipation component 310 to rise continuously, the embedded water dispenser also includes a hot air duct 500. The hot air duct 500 connects the hot air chamber 400 and the air outlet 2121, and a duct cooling fan 510 is installed inside the hot air duct 500. Some hot air can be discharged through the gap between the hot air chamber 400 and the outside, and after preliminary cooling by the hot air chamber 400, the flow rate and temperature of the hot air output by the hot air duct 500 can be lower than the hot air blown out by the cooling heat dissipation component 310. Thus, a large amount of hot air in the hot air chamber 400 can be drawn to the outside of the embedded water dispenser.

[0034] In the above technical solution, by setting up the hot air chamber 400, the external surface of the fan outlet 2121 is not obstructed, thus ensuring the fan exhaust rate of the cooling and heat dissipation component 310. By drawing a portion of the hot air from the hot air chamber 400 to the front of the embedded water dispenser through the hot air duct 500, the air temperature in the hot air chamber 400 can be reduced, preventing the temperature in the hot air chamber 400 from affecting the temperature of the cooling and heat dissipation component 310, further improving the efficiency of the cooling component. The air inlet 2111 is located far from the hot air chamber 400, ensuring that the air entering the embedded water dispenser is at a lower temperature, which also improves heat dissipation efficiency. In summary, through the above methods, the heat dissipation efficiency of the cooling component can be improved from multiple angles, avoiding performance degradation or problems with insufficient chilled water temperature.

[0035] Return to reference Figure 1 For example, the front panel 200 has a rearwardly recessed water receiving cavity 210, which has a first cavity sidewall 211 located on the same side as the first rear shell sidewall 110 and a second cavity sidewall 212 located on the same side as the second rear shell sidewall 120. The water receiving cavity 210 can serve as a space to accommodate the user's water container, allowing the user to dispense water without constantly holding the container. Furthermore, the recessed water receiving cavity 210 ensures that the embedded water dispenser does not protrude from the front panel 200. This prevents the user from bumping into protruding parts and injuring or damaging the embedded water dispenser. An air inlet 2111 is located on the first cavity sidewall 211, and an air outlet 2121 is located on the second cavity sidewall 212. This ensures that air blown from the front of the embedded beverage machine is not directly directed towards the user, but rather partially blown laterally, improving the user experience. The air inlet 2111 and air outlet 2121 located on the side wall are also less likely to be blocked by objects placed on them.

[0036] For example, the second cavity sidewall 212 has an inclined portion that slopes forward and in a second lateral direction, and the air outlet 2121 is disposed on the inclined portion, with the hot air duct 500 perpendicular to the inclined portion. Thus, the airflow from the cooling fan 510 is not obstructed and does not blow directly towards the user, ensuring airflow rate while avoiding impacting the user experience.

[0037] For example, the rear portion of the second rear shell sidewall 120 is recessed relative to its front portion in a first lateral direction, forming a hot air chamber 400. In addition... Figure 2 In addition to the embodiment shown, in other embodiments, the second rear shell sidewall 120 may also be provided with an arc-shaped inward portion, which can connect the second rear shell sidewall 120 and the rear shell rear wall. The hot air chamber 400 has a first heat dissipation vent 411 and a second heat dissipation vent 421 on its chamber wall. The cooling and heat dissipation assembly 310 is in fluid communication with the hot air chamber 400 through the first heat dissipation vent 411, and the hot air duct 500 is in fluid communication with the hot air chamber 400 through the second heat dissipation vent 421.

[0038] Compared to the embodiment where the second rear housing sidewall 120 is entirely recessed, the internal space of the embedded pipeline machine can be larger. Furthermore, sufficient space exists between the hot air chamber 400 and the air outlet 2121 to accommodate the hot air duct 500, allowing the airflow from the hot air duct 500 to reach the air outlet 2121 in a straight line, improving heat dissipation efficiency. Moreover, the entire hot air duct 500 can be a straight structure that is easy to manufacture, simplifying the machining of the rear housing 100.

[0039] Continue to refer to Figure 2For example, the hot air chamber 400 includes a first chamber wall 410 facing a second lateral direction and a second chamber wall 420 facing rearward. A first heat dissipation vent 411 is disposed on the first chamber wall 410, and a second heat dissipation vent 421 is disposed on the second chamber wall 420. The first heat dissipation vent 411 can be disposed on the first chamber wall 410. Since the first chamber wall 410 is relatively flat, it is convenient to install and fix the cooling and heat dissipation component 310, and it can fit snugly against the fan outlet 2121, eliminating the need for additional air ducts and preventing airflow leakage back into the rear shell 100. The second heat dissipation vent 421 can have a small gap from the first heat dissipation vent 411, thereby creating a lower air pressure in the area near the first heat dissipation vent 411, drawing some of the hotter air to the outlet 2121. This configuration of the hot air chamber 400 provides a sufficiently large volume, and simplifies the manufacturing of the rear shell 100.

[0040] For example, the area of ​​the air outlet 2121 is smaller than the area of ​​the first heat dissipation vent 411. As described above, the air duct cooling fan 510 only needs to blow a portion of the hot air from the first heat dissipation vent 411 to the air outlet 2121, so a smaller air outlet 2121 can be used. A smaller air outlet 2121 is not only more aesthetically pleasing but also does not damage the structure of the front panel 200. The air duct cooling fan 510 can be a centrifugal fan, which has a higher airflow rate, allowing for a larger air volume even with a smaller air outlet 2121. This further reduces the size of the air outlet 2121. For example, the second heat dissipation vent 421 is higher than the first heat dissipation vent 411. Since hot air has a lower density, the second heat dissipation vent 421 can draw most of the hot air from the first heat dissipation vent 411 to the air outlet 2121, thereby effectively improving heat dissipation efficiency.

[0041] For example, an additional air inlet 111 is provided on the side wall 110 of the first rear housing. This allows for the intake of cool air not only through the air inlet 2111 of the water dispenser, but also through the gap between the embedded water dispenser and the housing space 10. Figure 4As shown, the auxiliary air inlet 111 can have a larger air intake area than the air inlet 2111, resulting in less resistance to the entry of cold air. The auxiliary air inlet 111 and the air inlet 2111 are at least partially spaced apart, and can converge only when they reach the cooling and heat dissipation component 310. This ensures that the airflow from the air inlet 2111 and the airflow from the auxiliary air inlet 111 do not interfere with each other. In some embodiments, the air entering the embedded water dispenser mainly comes from the air inlet 2111, and the air around the auxiliary air inlet 111 may partially come from the hot air chamber 400, serving only as a supplement. In other embodiments, the air entering the embedded water dispenser mainly comes from the auxiliary air inlet 111, and there may be a large gap between the front panel 200 of the water dispenser and the opening of the receiving space 10, allowing more air to enter the receiving space 10 and then the auxiliary air inlet 111. In summary, the two can work together to allow cooler ambient air to enter the embedded water dispenser for heat dissipation. In some embodiments, the cooling fan 510 within the hot air duct 500 can have a large airflow rate, which, while drawing hot air from the hot air chamber 400, also promotes the entry of outside air into the accommodating space 10 through the aforementioned gaps. The additional air inlet 111 allows this cool air to participate in heat dissipation, improving the heat dissipation performance of the embedded pipeline machine.

[0042] For example, an additional air inlet 111 may be provided at the lower part of the first rear housing sidewall 110. This allows denser, cooler air to be drawn into the embedded pipeline unit, improving the heat dissipation efficiency of the cooling and heat dissipation assembly 310.

[0043] Return to reference Figure 3 For example, at least a portion of the first rear shell sidewall 110 is recessed inward relative to the first side edge toward the second lateral direction to form a cold air chamber 600, with an additional air inlet 111 disposed on the chamber wall of the cold air chamber 600. Similar to the hot air chamber 400, the cold air chamber 600 can be formed by the first rear shell sidewall 110 being spaced apart from the inner wall of the receiving space 10, thereby preventing the inner wall of the receiving space 10 from abutting against the additional air inlet 111, which would result in excessive air intake resistance. The cold air chamber 600 can also buffer the hot air from the hot air chamber 400. In the cold air chamber 600, relatively hot air can be mixed with a sufficient amount of cold air for cooling, and the warmer air floats at the top, ensuring that the air temperature entering through the additional air inlet 111 is relatively low.

[0044] Exemplarily, the embedded water dispenser also includes one or more of the following components: a water tank 710, an electronic control board 720, a heating element assembly 730, a waterproof water pump 740, and a solenoid valve assembly 750. The water tank 710 stores purified water from the water purifier, eliminating the need for the purifier to operate every time the user draws water, thus reducing the number of start-ups and shutdowns, decreasing noise, and extending the purifier's lifespan. The water tank 710 can be disposed within the inner cavity and in front of the cooling unit 300. The water tank 710 and the cooling unit 300 can have similar dimensions in their frontal projections, and placing them adjacent to each other improves space utilization. The waterproof water pump 740 is disposed in the lower part of the inner cavity; specifically, at least one waterproof water pump 740 can be disposed below the water tank 710 and the cooling unit 300. This shortens the pipe length between the three components, facilitating the waterproof water pump 740 to draw purified water from the water tank 710 and replenish the cooling unit 300. Even if the embedded water dispenser leaks, the waterproof water pump 740 located at the bottom will not be damaged. The control board 720 is also located within the inner cavity and adjacent to the first rear housing sidewall 110. The control board 720 generates relatively little heat and typically requires no additional cooling. In some embodiments, an additional air inlet 111 is located near the control board 720, allowing airflow to provide some additional cooling. The heating element assembly 730 is located in the front of the inner cavity and adjacent to the first rear housing sidewall 110. Positioning the heating element assembly 730 close to the front water inlet chamber 210 shortens the piping and prevents the hot water from cooling down after passing through the piping. Shorter piping also eliminates the need for insulation, reducing costs and assembly difficulty. The solenoid valve assembly 750 can be located in the lower part of the inner cavity. In some embodiments, the solenoid valve assembly 750 can be interspersed within the gap of the waterproof water pump 740 to improve the space utilization of the embedded water dispenser. The inlet and outlet of the embedded water dispenser are usually located at the bottom, and can be connected to the solenoid valve assembly 750 with a short pipe to control water supply and drainage.
