Water tank separated dehumidifier

Abstract

This invention provides a water tank-separated dehumidifier, including a dehumidifier main unit and a water tank. The inner wall of the water tank is provided with a limiting structure, which includes a limiting component and a floating component. The limiting component has a limiting position that prevents the dehumidifier main unit from entering the retracted state through the top opening, and a yielding position that allows the dehumidifier main unit to enter the retracted state through the top opening. The floating component can rise and fall under the buoyancy of the condensate collected in the water tank, locking the limiting component in the limiting position when the floating component rises to its highest point. This invention effectively prevents damage or safety hazards caused by the dehumidifier main unit being submerged due to condensate not draining from the water tank. Furthermore, since the height of the floating component is linked to the condensate level, there is no need for manual switching of the limiting component's position, making operation more convenient.

Description

Technical Field

[0001] This invention belongs to the field of dehumidifier design technology, specifically relating to a water tank-separated dehumidifier. Background Technology

[0002] With the development of the times and people's pursuit of a better life, dehumidifiers are constantly being upgraded and iterated, further enriching their functions, expanding their application scenarios, and miniaturizing their casings. In order to reduce the packaging size of dehumidifiers, a structure with a separate water tank and dehumidifier unit has emerged in the existing technology, namely the water tank separate dehumidifier. When not in use, the dehumidifier unit is stored in the water tank. When the dehumidifier unit is in use, it is lifted out of the water tank and placed above the water tank opening. At this time, the condensate water generated during the operation of the dehumidifier unit is collected and stored in the water tank. However, the common hidden danger of this type of dehumidifier is that if the condensate water in the water tank is not emptied in time or not emptied completely, the user will recycle the dehumidifier unit in the water tank, causing the dehumidifier unit to come into contact with or even be soaked in the condensate water. When it is powered on again, it may cause short circuit damage or even fire hazard, causing property damage or even personal injury to the user.

[0003] Due to the aforementioned shortcomings of water tank-separated dehumidifiers, existing technologies often employ methods such as installing detection electrodes inside the water tank to detect the presence and level of condensate, or using gravity detection to detect the presence of condensate. Both methods require corresponding electronic control systems, which are complex and increase the overall manufacturing cost of the dehumidifier. Another related technical solution uses a limiting structure on the inner wall of the water tank. This limiting structure has corresponding limiting components that restrict the dehumidifier unit's extension position when retracted into the water tank and allow it to retract. The extension position is achieved by the weight of the unit, while the retraction position requires manual force from the user. This manual repositioning method is inconvenient, and if the user is unfamiliar with the dehumidifier's operation, they may manually reposition the limiting components to the retracted position before retracting the unit, potentially leading to contact with condensate and subsequent damage or safety hazards. Summary of the Invention

[0004] Therefore, the present invention provides a water tank separation type dehumidifier, which can solve the technical problem in the prior art where the limiting structure set in the water tank needs to be manually reset, which is inconvenient to operate, and there is still a technical problem that user misoperation may cause the dehumidifier to come into contact with the condensate water, resulting in subsequent damage or safety hazards.

[0005] To address the aforementioned problems, this invention provides a water tank-separated dehumidifier, comprising a dehumidifier main unit and a water tank for collecting condensate generated by the dehumidifier main unit during operation. The dehumidifier main unit has an operating state and a recovery state. When the dehumidifier main unit is in the operating state, it is supported on the top opening of the water tank's water-containing space. When the dehumidifier main unit is in the recovery state, it is stored and recovered within the water-containing space.

[0006] The inner wall of the water tank is provided with a limiting structure, which includes a limiting component and a floating component. The limiting component has a limiting position that prevents the dehumidifier from being in the recovery state through the top opening, and a yielding position that allows the dehumidifier to be in the recovery state through the top opening. The floating component can rise and fall under the buoyancy of the condensate collected in the water tank, so that when the floating component rises to the highest position, the limiting component is locked in the limiting position.

[0007] In some implementations...

[0008] The limiting structure also includes a vertically extending boss formed on the inner wall of the water tank, and a vertically extending groove matching the shape of the boss is formed on one side wall of the dehumidifier. During the process of the dehumidifier switching from the operating state to the recycling state, the boss and the groove slide relative to each other.

[0009] In some implementations...

[0010] The floating element and / or at least part of the limiting component are located within the boss.

[0011] In some implementations...

[0012] The boss has a side wall perpendicular to the inner wall of the water tank. A limiting through hole is formed on the side wall. The limiting component includes a limiting member and an elastic member. The limiting member has a limiting head that can pass through the limiting through hole and protrude from the side wall, and a sliding guide body inside the boss. The elastic member can extend and retract to maintain the limiting head in the limiting position.

[0013] In some implementations...

[0014] The top surface of the free end of the limiting head has an inclined surface, the height of which decreases from the sliding guide towards the limiting head; and / or,

[0015] The limiting components are in two sets, and each set of limiting components is respectively disposed on the side walls opposite to each other on both sides of the boss. The floating member has a spacer portion. When each of the limiting components is in the limiting position, a limiting gap is formed between the sliding guides of the two limiting components. When the floating member is in the high point position, the spacer portion is within the limiting gap.

[0016] In some implementations...

[0017] The floating component also includes a buoyancy section at the bottom and a connecting section between the buoyancy section and the spacer section, wherein the cross-sectional area of ​​the buoyancy section is larger than the cross-sectional areas of the connecting section and the spacer section.

[0018] In some implementations...

[0019] The spacer portion is solid, while the connecting portion and the buoyancy portion are hollow; and / or, the connecting portion has hollowed-out weight-reducing holes.

[0020] In some implementations...

[0021] The first region is the position where the bottom wall of the water tank is opposite to the bottom end face of the buoyancy part. The first region has a water collection groove, and the cross-sectional area of ​​the water collection groove is not less than the cross-sectional area of ​​the buoyancy part.

[0022] In some implementations...

[0023] When both sets of the limiting components are in the limiting position, the protrusion of each limiting head from the side wall is h, where h ≥ 1 mm; and / or,

[0024] The horizontal width of the limiting interval is w, and the horizontal thickness of the interval is d, where 2mm ≤ d ≤ w.

[0025] In some implementations...

[0026] The boss includes support ribs formed on the inner wall of the water tank and a cover plate covering the outside of each support rib. An assembly sliding channel for each limiting component and a lifting sliding channel for the floating component are formed between each support rib. A flow hole is formed in the bottom area of ​​the cover plate.

[0027] The present invention provides a water tank separation type dehumidifier, which has the following beneficial effects:

[0028] The limiting structure includes a limiting component and a floating component. The floating component can rise under the buoyancy of the condensate collected in the water tank. When the condensate level is at its maximum, the floating component will be at the aforementioned high point, thus causing the limiting component to be in the limiting position. If the user tries to recycle and store the dehumidifier in the water tank in this state, the dehumidifier will not be able to be placed smoothly. This effectively prevents damage or safety hazards caused by the dehumidifier being submerged due to condensate not being drained from the water tank. At the same time, since the height of the floating component is linked to the condensate level, there is no need to manually switch the position of the limiting component, making the operation more convenient.

[0029] By sliding between the protrusion on the inner wall of the water tank and the groove on the side wall of the dehumidifier, the smooth switching process of the dehumidifier from the running state to the recycling state can be ensured.

[0030] By placing the floating components and limiting components inside the boss, the internal structural design of the water tank can be simplified, resulting in a compact structure.

[0031] The aforementioned cover plate can be reliably connected to the outermost edge of the supporting ribs through a snap-fit ​​connection, while the floating parts and limiting components are hidden and confined inside by the cover plate, resulting in a higher overall integrity of the limiting structure.

[0032] The elastic element allows the limiting component to be in the limiting position when there is no retraction force on the outer side of the limiting head. In this case, it can be understood that when the condensate in the water tank has not been drained, the floating element is in the high position, locking the position of the limiting head. When the condensate in the water tank has been drained, the floating element falls to the low position due to the lack of buoyancy. If the user retracts and stores the dehumidifier in the water tank, the sliding fit between the groove and the boss will apply force to the limiting head during the process of moving it under the dehumidifier, causing it to overcome the elastic element and retract to the yielding position.

[0055] See also Figures 1 to 9As shown in the embodiment of the present invention, a water tank separation type dehumidifier is provided, including a dehumidifier main unit 1 and a water tank 2 for collecting the condensate generated by the dehumidifier main unit 1 during operation. As is known in the industry, the aforementioned dehumidifier main unit 1 includes various components of a conventional dehumidifier that achieve its dehumidification function, such as a compressor, a throttling element, and two heat exchangers (evaporator and condenser), etc., which are not particularly limited here. The dehumidifier main unit 1 has an operating state and a recovery state. The aforementioned operating state is the state in which the dehumidifier main unit 1 achieves the purpose of dehumidifying the target space, while the recovery state refers to the state in which the dehumidifier main unit 1 is housed and contained within the water tank 2. Specifically, when the dehumidifier main unit 1 is in the operating state, the dehumidifier main unit 1 is supported on the top opening of the water-containing space (not indicated in the figure) of the water tank 2. When the dehumidifier main unit 1 is in the recovery state, the dehumidifier... The dehumidifier 1 is stored and recycled in the water-containing space. The inner wall of the water tank 2 is also provided with a limiting structure, which includes a limiting component and a floating component 32. The limiting component has a limiting position that prevents the dehumidifier 1 from being in the recycled state through the top opening and a yielding position that allows the dehumidifier 1 to be in the recycled state through the top opening. The floating component 32 can rise and fall under the buoyancy of the condensate collected in the water tank 2, so that when the floating component 32 rises to the high point, the limiting component is locked in the limiting position. It is understood that when the condensate in the water tank 2 is discharged, due to the lack of buoyancy of the condensate, the floating component 32 will fall to the low point, thereby releasing the locking of the limiting component. At this time, the limiting component is in the yielding position, and the dehumidifier 1 can be switched to the recycled state.

[0056] In this technical solution, the limiting structure includes a limiting component and a floating component 32. The floating component 32 can rise under the buoyancy of the condensate collected in the water tank 2. When the condensate level is at its maximum, the floating component 32 will be at the aforementioned high point, thus causing the limiting component to be in the limiting position. At this time, if the user retrieves the dehumidifier 1 and stores it in the water tank 2 in this state, the dehumidifier 1 will not be able to be placed smoothly. This effectively prevents damage or safety hazards caused by the dehumidifier 1 being submerged in water due to the condensate not being drained from the water tank 2. At the same time, since the height of the floating component 32 is linked to the condensate, there is no need to manually switch the position of the limiting component, making the operation more convenient.

[0057] In a preferred embodiment, the limiting structure further includes a vertically extending boss 33 formed on the inner wall of the water tank 2, and a vertically extending groove 11 matching the shape of the boss 33 is formed on one side wall of the dehumidifier 1. During the process of the dehumidifier 1 switching from the operating state to the recycling state, the boss 33 and the groove 11 slide relative to each other.

[0058] In this technical solution, the sliding connection between the protrusion 33 on the inner wall of the water tank 2 and the groove 11 on the side wall of the dehumidifier 1 ensures a smooth transition of the dehumidifier 1 from the operating state to the recycling state. It is understood that the horizontal width of the aforementioned protrusion 33 and the horizontal width of the groove 11 should be approximately equal.

[0059] In a preferred embodiment, two protrusions 33 may be provided, with the two protrusions 33 respectively provided on two opposite inner wall surfaces of the water tank 2. In this way, when the dehumidifier 1 is in operation, it can be more stably mounted on the top end surfaces of the two protrusions 33, ensuring the stable operation of the dehumidifier 1. When the dehumidifier 1 is in the retracted state, the two protrusions 33 are slidably assembled with the two grooves 11 respectively.

[0060] In some embodiments, the floating member 32 and / or at least a portion of the limiting component are both located within the boss 33; specifically, see [link to relevant documentation]. Figure 4 As shown, the floating component 32 is assembled entirely within the boss 33, while the limiting component has a portion that protrudes from the side wall of the boss 33. This protruding portion can obstruct the switching of the dehumidification unit 1's recovery state, thereby preventing potential hazards caused by storing condensate in the water tank 2 before it is drained. In this technical solution, both the floating component 32 and the limiting component are housed within the boss 33, which simplifies the internal structural design of the water tank 2 and results in a compact structure.

[0061] See details Figure 4 As shown, the boss 33 includes support ribs 332 formed on the inner wall of the water tank 2 and cover plates 333 covering the outside of each support rib 332. Assembly sliding channels (not labeled in the figure) for each limiting component and lifting sliding channels (not labeled in the figure) for the floating component 32 are formed between each support rib 332. The bottom area of ​​the cover plate 333 is constructed with flow holes 334.

[0062] In this technical solution, the aforementioned cover plate 333 can be reliably connected to the outermost edge of the support rib 332 through a snap-fit ​​connection, while the floating part 32 and the limiting component are hidden and limited inside by the cover plate 333, resulting in a higher overall integrity of the entire limiting structure.

[0063] In some embodiments, the boss 33 has a side wall perpendicular to the inner wall of the water tank 2. A limiting through hole 331 is formed on the side wall. The limiting assembly includes a limiting member 311 and an elastic member 312. The limiting member 311 has a limiting head 3111 that can pass through the limiting through hole 331 and protrude from the side wall, and a sliding guide 3112 located inside the boss 33. The elastic member 312 can telescopically maintain the limiting head 3111 in the limiting position. The aforementioned elastic member 312 is, for example, a metal coil spring, one end of which is connected to the inner side of the limiting head 3111, and the other end forms a limiting connection with a component (e.g., a support rib 332) within the boss 33. Specifically, the aforementioned sliding guide 3112 slides within the assembly sliding channel.

[0064] In this technical solution, the elastic element 312 can keep the limiting component in the limiting position when the outer side of the limiting head 3111 is not subjected to the retraction force. It can be understood that when the condensate in the water tank 2 has not been discharged, the floating element 32 is in the high position, locking the position of the limiting head 3111. When the condensate in the water tank 2 has been discharged, the floating element 32 falls to the low position due to the lack of buoyancy. At this time, if the user retracts and stores the dehumidifier 1 in the water tank 2, the sliding cooperation between the groove 11 and the boss 33 will apply force to the limiting head 3111 during the process of moving the dehumidifier 1 below, thereby making it overcome the elastic element 312 and retract to the yielding position.

[0065] See details Figure 8 As shown in state 1, the aforementioned elastic member 312 applies force to the limiting head 3111, causing it to protrude from the side wall. At this time, the elastic member 312 can be in a free state or a slightly compressed state, meaning the limiting member 311 is in a limited position. When the position of the limiting member 311 is not restricted by the floating member 32, see [the diagram]. Figure 8 As shown in state 3, when the user places the dehumidifier 1 into the water tank 2, force will be applied to the limiting head 3111 and the compressor elastic element 312 during the placement process. At this time, the limiting head 3111 retracts into the aforementioned side wall, and the limiting element 311 is in the yielding position.

[0066] As a preferred embodiment, the top surface of the free end of the limiting head 3111 has an inclined surface, and the height of the inclined surface decreases from the sliding guide 3112 to the limiting head 3111. That is, the limiting head 3111 is a wedge structure. In this way, when the dehumidifier 1 is placed in the water tank 2, if the floating part 32 is at the lowest point at the same time, the limiting head 3111 can switch its position from the limiting position to the yielding position during the storage and descent of the dehumidifier 1, making the operation more convenient.

[0067] In a preferred embodiment, see Figure 6 As shown, the limiting components have two sets, and each set of the limiting components is respectively disposed on the side walls of the protrusion 33 facing away from each other. The floating member 32 has a spacer 321. When all the limiting components are in the limiting position, a limiting interval is formed between the sliding guides 3112 of the two limiting members 311, that is, the two limiting heads 3111 are disposed facing away from each other. When the floating member 32 is in the high point position, the spacer 321 is within the limiting interval.

[0068] In this technical solution, by setting a set of the aforementioned limiting components on each of the opposite sides of the boss 33, the limiting reliability when it is locked in the limiting position can be improved.

[0069] See details Figure 4 As shown, in some embodiments, the floating member 32 further includes a buoyancy part 322 at the bottom and a connecting part 323 connecting the buoyancy part 322 and the spacer part 321, wherein the cross-sectional area of ​​the buoyancy part 322 is larger than the cross-sectional area of ​​the connecting part 323 and the spacer part 321.

[0070] In this technical solution, the cross-sectional area of ​​the bottom buoyancy part 322 is larger than the cross-sectional area of ​​the upper interval part 321 and the connecting part 323, which can ensure that the condensate has a large buoyancy, thereby ensuring the linkage response rate between the floating part 32 and the condensate water level.

[0071] In some embodiments, the spacer 321 is a solid body to improve its resistance to deformation, that is, to ensure that the limiting members 311 on its left and right sides are stably and reliably in their limiting positions, thus ensuring the effective functioning of its limiting function.

[0072] Both the connecting part 323 and the buoyancy part 322 are hollow bodies, which can reduce the mass of the entire floating part 32 and further improve the sensitivity of the linkage response between the floating part 32 and the condensate water level; furthermore, the connecting part 323 has a hollow weight-reducing hole 3231, which can further reduce the overall mass of the floating part 32.

[0073] In some embodiments, the position where the bottom wall of the water tank 2 is opposite to the bottom end face of the buoyancy part 322 is a first region, and the first region has a water collection groove (not shown in the figure), the cross-sectional area of ​​the water collection groove is not less than the cross-sectional area of ​​the buoyancy part 322.

[0074] In this technical solution, by setting a water collection groove on the bottom wall of the water tank 2 below the buoyancy part 322, it is possible to effectively prevent the water level in the water tank 2 from being too high even when the amount of condensate in the water tank is small, thereby ensuring that the buoyancy force on the floating part 32 is large enough.

[0075] In another preferred embodiment, the top surface of the bottom wall of the water tank 2 is an inclined surface that slopes toward the water collection groove, which facilitates the concentration of condensate in the water tank 2 into the aforementioned water collection groove when there is little condensate.

[0076] In one specific embodiment, when both sets of the limiting components are in the limiting position, the protrusion amount of each limiting head 3111 protruding from the side wall is h (e.g., Figure 9 (as shown), h≥1mm; and / or, the horizontal width of the limiting interval is w (as shown). Figure 9 As shown in the figure, the horizontal thickness of the spacer 321 is d (as shown in the figure). Figure 9 As shown in the figure, 2mm≤d≤w, to ensure that the limit head 3111 reliably limits the dehumidification unit 1.

[0077] like Figure 8 As shown, the specific operation of the aforementioned water tank separation type dehumidifier is as follows:

[0078] (1) When there is no water in the water tank 2, after the dehumidifier 1 is lifted out of the water tank 2, the limit head 3111 is stretched outward by the elastic force of the elastic element 312, and the floating element 32 does not move, as shown in state 1 in the figure.

[0079] (2) When the dehumidifier 1 is running and there is water in the water tank 2, the limiting head 3111 extends outward due to the elastic force of the elastic element 312, and the floating element 32 moves upward due to the buoyancy of the water, pushing the interval part 321 into the limiting interval, thus restricting the limiting head 3111 from retracting. When the dehumidifier 1 is installed at this time, it will be blocked by the limiting head 3111 and cannot be installed into the water tank 2.

[0080] (3) When the water in the water tank 2 is drained, the floating part 32 will fall back without buoyancy support, and the interval part 321 will exit from the limit interval, releasing the restriction on the retraction of the limit head 3111. At this time, when the main unit 1 is installed, the limit head 3111 is squeezed by the groove 11 of the dehumidification main unit 1 and retracts into the boss 33, thus achieving the purpose of installing the dehumidification main unit 1.

[0081] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention. The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the protection scope of the present invention.
