Abstract
Description
Technical Field
[0001] This application relates to the technical field of dehumidifiers, and in particular to a dehumidifier with an upper-mounted water tank. Background Technology
[0002] A dehumidifier is an air handling device that reduces air humidity through the principle of condensation. It mainly includes core components such as a compressor, heat exchanger (condenser and evaporator), fan, water tank, casing, and controller. The fan draws humid air into the machine, where it is cooled by the evaporator, causing the water vapor to condense into liquid water which is collected in the water tank. The dried air is then heated by the condenser before being discharged, thus regulating the ambient humidity.
[0003] In related technologies, dehumidifiers generally use a bottom-mounted water tank, which is fixed to the bottom or side of the equipment. Condensate drips down from the evaporator and flows into the base water tank. When the water level reaches the set height, the level switch triggers the water pump to pump the water to the water tank for temporary storage.
[0004] Regarding the aforementioned technologies, the water tank is typically connected to the main unit via a pull-out or side-sliding method, requiring the user to manually empty the tank when full. The low installation position of the bottom-mounted water tank means that when full, the user must bend over or squat to remove it before emptying and cleaning, making the process inconvenient. Utility Model Content
[0005] To address the issue of the inconvenience of removing the bottom-mounted water tank and improve the ease of cleaning the dehumidifier's water tank, this application provides a dehumidifier with a top-mounted water tank.
[0006] The dehumidifier with a top-mounted water tank provided in this application adopts the following technical solution: A dehumidifier with an upper water tank includes a housing, a water tank, a base water trough, an evaporator and a condenser disposed inside the housing, and a water supply pipeline assembly for conveying condensate from the base water trough to the water tank. The base water trough is installed at the bottom of the housing and is supported below the evaporator and the condenser. The water supply pipeline assembly is installed on the inner wall of the housing. The outer casing of the machine body has an upper mounting cavity on one side for placing the water tank, and a cover plate for closing the water tank is movably connected to the outer casing of the machine body.
[0007] By adopting the above technical solution, the water tank is placed in the mounting cavity at the top of the unit's outer casing, improving the inconvenience of accessing water from a bottom-mounted water tank. Users can easily remove and empty the water tank without bending over or squatting, reducing physical strain and making it more user-friendly for the elderly, pregnant women, and other special groups. Simultaneously, the water tank's connection to the outer casing via a movable cover ensures installation stability and facilitates daily cleaning and maintenance. The water supply piping assembly, arranged along the inner wall, further optimizes the spatial layout, reducing the risk of structural wear due to frequent pulling and retraction, and enhancing the dehumidifier's ease of use and user experience.
[0008] Furthermore, the outer casing includes two oppositely arranged side panels, a lower panel, an upper panel, a middle partition, and a back panel integrally connected between the two side panels. The middle partition is arranged horizontally and perpendicular to the two side panels. The lower panel and the upper panel are both arranged vertically. The lower panel is vertically fixedly connected to the edge of the middle partition and located below the middle partition. The upper panel is vertically fixedly connected to the edge of the middle partition away from the lower panel and located above the middle partition. The middle partition and the upper panel together form a stepped mounting cavity for installing the water tank. The back panel is arranged vertically and fixedly connected to the side of the two side panels away from the lower panel.
[0009] By adopting the above technical solution, the vertical fixed connection of the side panels, lower panel, upper panel, and middle partition creates a modular cabinet structure. The stepped mounting cavity formed by the middle partition and upper panel provides a suitable positioning space for the water tank, ensuring the stability of the water tank installation. The water tank is installed at the top of the unit, allowing users to directly access and remove it without bending or squatting, significantly reducing physical strain during operation. The top-mounted water tank is connected to the unit frame via the modular mounting cavity. The vertical support structure of the side panels, middle partition, and back panel forms a rigid frame, reducing water tank displacement caused by operational vibrations. The fixed connection between the back panel and the side panels seals the side openings of the cabinet, forming a complete protective structure with other panels, reducing the probability of external dust and foreign objects intruding into internal components.
[0010] Furthermore, the water supply pipeline assembly includes a water pipe body, a level gauge, and a miniature water pump. The miniature water pump is fixedly connected to the inner wall of the side panel. The level gauge is installed in the bottom water tank and electrically connected to the miniature water pump. The water pipe body passes through the miniature water pump and its lower end extends into the base water tank. The upper end of the water pipe body passes through the upper panel and extends into the mounting cavity. The upper panel has a clearance groove at its upper edge for the end of the water pipe body to pass through.
[0011] By adopting the above technical solution, the micro water pump and level gauge are designed in tandem to achieve intelligent drainage control of the water tank. The level gauge monitors the water level in the base tank in real time. When the threshold is reached, it triggers the micro water pump to start, automatically transporting condensate to the upper water tank through the water pipe, avoiding the cumbersome manual emptying required for traditional lower water tanks. The water pipe passes through the micro water pump and extends to the upper panel. The pipe routing is optimized using the space inside the side panel, and the end is fixed by a clearance groove, ensuring sealing and preventing leakage caused by pipe swaying during operation.
[0012] Furthermore, on the side of the upper panel away from the water tank, at the location of the relief groove, there is a water pipe guide wheel for supporting the water pipe and a U-shaped mounting seat for installing the water pipe guide wheel. The water pipe guide wheel is rotatably connected to the U-shaped mounting seat, and the outer peripheral wall of the water pipe guide wheel has a supporting ring groove that matches the outer wall of the water pipe body.
[0013] By adopting the above technical solution, the supporting annular groove on the outer circumference of the water pipe guide wheel fits tightly against the outer wall of the water pipe body, forming a stable contact support interface. When the water pipe experiences local bending stress due to its own weight or pipeline layout, the guide wheel supports the outer wall of the water pipe through the annular groove, dispersing the concentrated bending force to the annular support surface of the guide wheel, effectively reducing the pressure per unit area of the water pipe and preventing pipe wall collapse and deformation caused by local pressure. The rotatable connection between the guide wheel and the U-shaped mounting base allows the guide wheel to rotate freely with slight displacement of the water pipe, reducing the sliding friction resistance between the water pipe and the guide wheel, reducing the risk of pipe wall wear caused by friction, and adapting to the slight deformation of the water pipe caused by temperature changes or vibration during long-term use, always maintaining the roundness of the water pipe cross-section, thereby preventing problems such as poor water flow or even blockage caused by deformation and flattening of the water pipe.
[0014] Furthermore, the U-shaped mounting base has a clearance notch on its bottom side that matches the outer wall of the water pipe body.
[0015] By adopting the above technical solution, the depth of the reserved clearance notch matches the outer wall of the water pipe, forming a clearance space. When the cover is opened / closed, the water pipe can be completely embedded in the notch, avoiding direct contact between the edge of the cover and the outer wall of the water pipe.
[0016] Furthermore, a horizontal support plate for supporting the water pipe body is fixedly connected to the side of the upper panel near the water tank at the location of the relief groove. The horizontal support plate has an arc-shaped groove that matches the outer wall of the water pipe body.
[0017] By adopting the above technical solution, the horizontal support plate fits tightly against the outer wall of the water pipe through an arc-shaped groove, directly supporting the end of the water pipe. In actual use, the curvature of the groove matches the outer diameter of the water pipe, stably supporting the water pipe and preventing it from sag due to gravity, causing friction or bending deformation with surrounding components. At the same time, the arc-shaped groove increases the contact area between the water pipe and the support plate, reducing local pressure and avoiding pipe wall indentation caused by long-term pressure. This ensures the smooth flow of condensate water and reduces drainage problems caused by pipe deformation or blockage.
[0018] Furthermore, the cover plate is hinged to the top edge of the upper panel, and a clearance groove is provided on the bottom side of the cover plate at the position of the horizontal support plate for the water pipe body to be inserted. The clearance groove is arranged vertically and vertically corresponding to the arc-shaped groove.
[0019] By adopting the above technical solution, the cover plate is hinged to the top side of the upper panel. When the water tank needs to be removed, there is no need to disassemble the surrounding structure; simply lift the cover plate upwards to expose the water tank, making operation convenient. The cover plate presses the water pipe firmly against gravity and prevents its lateral displacement through the upper groove. The horizontal support plate supports the weight of the water pipe to prevent sagging, and the arc-shaped groove prevents the water pipe body from being flattened.
[0020] Furthermore, the base water tank is vertically fixedly connected with multiple spaced guide plates, each of which is located below the evaporator and the condenser.
[0021] By adopting the above technical solution, the guide plate guides the condensate generated by the evaporator along a preset trajectory, so that the condensate can be delivered to the water tank in a timely manner by the water supply pipeline assembly, avoiding water accumulation that could lead to bacterial growth.
[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. The water tank is moved to the upper mounting cavity, allowing users to easily remove and place it without bending or squatting, making it more user-friendly for the elderly and pregnant women. The hinged cover opens upwards without disassembling surrounding parts, allowing for one-handed operation and quick exposure of the water tank for easy cleaning. The stepped mounting cavity formed by the central partition and side panels ensures the water tank's stability and isolates it from internal components, reducing dust intrusion. When the cover is closed, gravity presses firmly against the water pipes to prevent shaking and noise, while the sealed structure prevents condensation from overflowing. 2. The water supply pipeline is arranged along the inner wall to avoid exposed pipelines. The U-shaped mounting base cooperates with the water pipe guide wheel to fix the pipeline, allowing for slight displacement and reducing bending wear. The arc-shaped groove of the horizontal support plate and the groove of the cover plate form double support to prevent the water pipe from being deformed under pressure. Even with long-term use, it can maintain smooth drainage and reduce the risk of blockage. 3. The baffle plate precisely guides the condensate to the water pipe inlet and is then pumped to the water tank by the water pump, preventing water accumulation in the base water tank and the growth of bacteria. The miniature water pump and the level gauge work together to achieve automatic drainage. Attached Figure Description

[0031] To make the purpose, technical solution, and advantages of this application clearer, the following description is provided in conjunction with the appendix. Figure 1-7 The present application will be further described in detail with reference to the embodiments.
[0032] This application discloses a dehumidifier with a top-mounted water tank. (Refer to...) Figure 1 , Figure 2 and Figure 3 The dehumidifier's water tank 2 structure includes a casing 1, a water tank 2, a cover plate 3, a base water trough 4, an evaporator 5, a condenser 6, and a water supply pipeline assembly 7.
[0033] Reference Figure 3 and Figure 4 The outer casing 1 includes two oppositely arranged side panels 11, a lower panel 12 integrally connected between the two side panels 11, an upper panel 13, a middle partition 14, and a back panel 15. The middle partition 14 is arranged horizontally and perpendicular to the two side panels 11, while the lower panel 12 and upper panel 13 are both arranged vertically. The lower panel 12 is vertically fixed to the edge of the middle partition 14 and located below the middle partition 14, while the upper panel 13 is vertically fixed to the edge of the middle partition 14 away from the lower panel 12 and located above the middle partition 14. The top side of the middle partition 14 and the upper panel 13 together form a stepped mounting cavity 141 for installing the water supply tank 2. The back panel 15 is arranged vertically and fixedly connected to the side of the two side panels 11 away from the lower panel 12.
[0034] In this embodiment, the partition 14 separates the mounting cavity 141 in the upper part of the entire body, thereby achieving the effect of placing the water tank 2 on the top. The mounting cavity 141 is an open mounting cavity, which facilitates the installation and disassembly of the water tank 2. The cover plate 3 is hinged to the top edge of the upper panel 13 to cover the water tank 2.
[0035] The two side panels 11, the back panel 15, the lower panel 12, and the bottom of the middle partition 14 together form a closed internal chamber 142. The evaporator 5 and the condenser 6 are installed in the internal chamber 142 and located below the middle partition 14. Figure 5 The base water tank 4 is installed at the bottom of the outer casing 1 and is supported below the evaporator 5 and condenser 6 to collect condensate. The base water tank 4 has multiple spaced guide plates 41 vertically fixed inside, and each guide plate 41 is located below the evaporator 5 and condenser 6.
[0036] A water supply pipeline assembly 7 is installed on the inner wall of the side panel 11 to transport condensate from the base water tank 4 to the water tank 2. The water supply pipeline assembly 7 includes a water pipe body 71, a level gauge 72, and a miniature water pump 73. The miniature water pump 73 is fixedly connected to the inner wall of the side panel 11, and the level gauge 72 is installed in the bottom water tank and electrically connected to the miniature water pump 73. The water pipe body 71 passes through the miniature water pump 73 and extends its lower end into the base water tank 4. The upper end of the water pipe body 71 passes through the upper panel 13 and extends into the mounting cavity 141. The upper panel 13 has a clearance groove 131 at its upper edge for the end of the water supply pipe body 71 to pass through.
[0037] The miniature water pump 73 and the level gauge 72 work together to achieve intelligent drainage control of the water tank 2. The level gauge 72 monitors the water level in the base water tank 4 in real time. When the water level reaches a threshold, it triggers the miniature water pump 73 to start, automatically transporting condensate to the upper water tank 2 through the water pipe body 71. The water pipe body 71 passes through the miniature water pump 73 and extends to the upper panel 13. The pipe routing is optimized by utilizing the inner wall space of the side upright plate 11, and the end is fixed by the clearance groove 131.
[0038] Reference Figure 6 and Figure 7 On the side of the upper panel 13 away from the water tank 2, at the location of the clearance groove 131, there is a water pipe guide wheel 132 for supporting the water pipe and a U-shaped mounting seat 133 for mounting the water pipe guide wheel 132. The water pipe guide wheel 132 is rotatably connected to the U-shaped mounting seat 133. The U-shaped mounting seat 133 has a clearance notch 1331 on its bottom side that matches the outer wall of the water pipe body 71. The outer peripheral wall of the water pipe guide wheel 132 has a supporting ring groove 1321 that matches the outer wall of the water pipe body 71.
[0039] On the side of the upper panel 13 near the water tank 2, a horizontal support plate 134 for supporting the water pipe body 71 is fixedly connected at the relief groove 131. The horizontal support plate 134 has an arc-shaped groove 1341 that matches the outer wall of the water pipe body 71. The cover plate 3 has a relief groove 31 at the position of the horizontal support plate 134 for the water pipe body 71 to be inserted. The relief groove 31 and the arc-shaped groove 1341 are arranged vertically and vertically respectively.
[0040] The supporting annular groove 1321 on the outer periphery of the water pipe guide wheel 132 fits tightly against the outer wall of the water pipe body 71, forming a stable contact support interface. When the water pipe experiences local bending stress due to its own weight or pipeline layout, the guide wheel supports the outer wall of the water pipe through the annular groove, dispersing the concentrated bending force to the annular support surface of the guide wheel, effectively reducing the pressure borne by the water pipe per unit area, and avoiding pipe wall collapse and deformation caused by local pressure.
[0041] The rotatable connection between the water pipe guide wheel 132 and the U-shaped mounting base 133 allows the guide wheel to rotate freely with slight displacement of the water pipe, reducing the sliding friction resistance between the water pipe and the guide wheel, maintaining the roundness of the water pipe cross-section, and preventing problems such as poor water flow or even blockage caused by deformation and flattening of the water pipe. The depth of the clearance notch 1331 reserved in the U-shaped mounting base 133 matches the outer wall of the water pipe, forming a clearance space. When the cover plate 3 is opened / closed, the end of the water pipe body 71 can be completely embedded in the clearance notch 1331, avoiding direct contact between the edge of the cover plate 3 and the outer wall of the water pipe, thus preventing compression.
[0042] The horizontal support plate 134 fits tightly against the outer wall of the water pipe through the arc-shaped groove 1341, directly supporting the end of the water pipe. In actual use, the curvature of the groove matches the outer diameter of the water pipe, stably supporting the water pipe and preventing it from sag due to gravity, causing friction or bending deformation with surrounding components. At the same time, the arc-shaped groove 1341 increases the contact area between the water pipe and the support plate, reduces local pressure, avoids pipe wall indentation caused by long-term pressure, ensures the smooth flow of condensate water, and reduces drainage problems caused by water pipe deformation or blockage.
[0043] The implementation principle of a dehumidifier with a top-mounted water tank according to an embodiment of this application is as follows: The water tank 2 is integrated into the mounting cavity 141 at the top of the unit. An open stepped structure is constructed using the partition plate 14 and the side plate, allowing the water tank 2 to be directly opened and placed in the unit without bending over or squatting, significantly reducing the operational threshold. The spaced guide plates 41 in the base water tank 4 form a directional condensate flow channel. With the linkage control of the micro water pump 73 and the level gauge 72, the condensate is automatically pumped out, preventing water accumulation and bacterial growth. The water supply pipeline is doubly supported by the guide wheels of the U-shaped mounting base 133 and the arc-shaped groove 1341 of the horizontal support plate 134. This not only disperses the force on the water pipe to prevent deformation but also allows for slight displacement to adapt to equipment vibration. At the same time, the clearance notch 1331 allows for flexible avoidance when the cover 3 is closed. The hinged design of the cover 3, combined with a gravity clamping mechanism, simplifies the cleaning process while ensuring sealing. The overall structure improves drainage efficiency and reduces component wear through spatial reconstruction and dynamic flow guidance, balancing ease of use and equipment durability.
[0044] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
