Description

Technical Field

[0001] This utility model belongs to the field of air conditioning technology, specifically relating to a dehumidifier. Background Technology

[0002] Current dehumidifier products employ various drainage structures. Some designs integrate the water pump's suction and drainage mechanisms, along with the float controlling its operation, into the water tray. The pump draws water from the tray via a suction pipe and discharges the condensate through a drain pipe and outlet. The pump starts when the float reaches full capacity and stops after a certain time. However, this method, where the pump directly draws and discharges the condensate from the tray, results in the condensate being drained quickly due to the tray's small capacity, leading to frequent pump starts and stops or even dry runs, thus reducing the pump's lifespan. Other designs utilize a water tank in conjunction with the water tray. The pump draws the condensate from the tray into a larger tank, and a float in the tray detects the water level and controls the pump's operation. However, this larger tank configuration, with the pump and float working together, also suffers from the drawback of frequent pump starts and stops, reducing the pump's lifespan. Utility Model Content

[0003] Therefore, this utility model provides a dehumidifier that can overcome the technical problem in related technologies where a water pump is used to suck and discharge condensate collected in a small water tray, and the frequent start and stop of the water pump reduces the service life of the water pump.

[0004] To address the aforementioned problems, this utility model provides a dehumidifier, including a water receiving tray and a water tank. The water receiving tray has a water storage pool, and the water storage pool and the water tank are connected in the bottom area to form a communicating vessel structure. It also includes a water pump assembly, which includes a water pump. The inlet of the water pump's suction pipe is located in the bottom area of ​​the water storage pool. When the water pump is running, it can discharge the condensate stored in the water storage pool to the outside of the dehumidifier.

[0005] In some embodiments, the bottom area of ​​the water tank has a water tank docking mechanism, the bottom area of ​​the water storage tank has a water storage tank docking mechanism, and the water tank and the water storage tank are connected and connected through the water tank docking mechanism and the water storage tank docking mechanism; and / or, a liquid level detection component is provided in the water tank for detecting the real-time liquid level of the condensate in the water tank.

[0006] In some embodiments, the water tank docking mechanism includes a first pair of connecting pipes, and the water storage tank docking mechanism includes a second pair of connecting pipes. The water tank has a water storage and connection state and a disconnected and emptied state. When the water tank is in the water storage and connection state, the water tank docking mechanism and the water storage tank docking mechanism are connected to each other, and the first pair of connecting pipes and the second pair of connecting pipes are interlocked. When the water tank is in the disconnected and emptied state, the water tank docking mechanism and the water storage tank docking mechanism are separated from each other, and the flow of the first pair of connecting pipes and the second pair of connecting pipes is cut off.

[0007] In some embodiments, a first on / off valve assembly and a first ejector structure extending toward the second pair of pipes are assembled inside the first pair of pipes. The water storage tank has a second on / off valve assembly capable of controlling the on / off of the second pair of pipes and a second ejector structure located inside the second pair of pipes and extending toward the first pair of pipes. When the water tank is in the water storage connection state, the first ejector structure applies force to the second on / off valve assembly to enable flow through the second pair of pipes, and the second ejector structure applies force to the first on / off valve assembly to enable flow through the first pair of pipes.

[0008] In some embodiments, the first on / off valve assembly includes a first valve stem and a first valve plate fixedly connected to a first end of the first valve stem. A first support structure is formed within the first connecting pipe. The first valve stem is slidably assembled onto the first support structure along the axial direction of the first connecting pipe. A first elastic element is fitted onto the first valve stem and is clamped between the first support structure and a second end of the first valve stem. A second ejector structure applies force to the second end of the first valve stem to overcome the elastic force of the first elastic element, thereby forming a flow gap between the first valve plate and the opening of the first connecting pipe. Alternatively, the second on / off valve assembly includes a second valve stem and a second valve plate fixedly connected to a first end of the second valve stem. A second support structure is formed within the water storage tank. The second valve stem is slidably assembled onto the second support structure along a direction parallel to the axial direction of the second connecting pipe. A second elastic element is fitted onto the second valve stem and is clamped between the second support structure and a second end of the second valve stem. The first ejector structure applies force to the first end of the second valve stem to overcome the elastic force of the second elastic element, thereby forming a flow gap between the second valve plate and the opening of the second connecting pipe.

[0009] In some embodiments, the first valve stem and the second valve stem are arranged parallel to each other and spaced apart; and / or, the second pair of connecting pipes is sleeved on the radially outer side of the first pair of connecting pipes, and a sealing ring is provided between the first pair of connecting pipes and the second pair of connecting pipes; and / or, the second valve plate and the second valve stem are integrally formed; and / or, an annular groove for fitting and positioning the second elastic element is formed on the side of the second valve plate facing the second end of the second valve stem.

[0010] In some embodiments, the second on / off valve assembly includes a second valve stem and a second valve plate fixedly connected to a first end of the second valve stem. A second support structure is formed in the water storage tank. The second valve stem is slidably assembled on the second support structure in a direction parallel to the axial direction of the second connecting pipe. A magnetic attraction assembly is provided between the second valve plate and the opening of the second connecting pipe. The first ejection structure can apply force to the first end of the second valve stem to overcome the magnetic attraction force of the magnetic attraction assembly, thereby forming a flow gap between the second valve plate and the opening of the second connecting pipe.

[0011] In some embodiments, an installation platform is formed on the outer wall of the top region of the water storage tank, and the water pump is assembled on the installation platform; and / or, the water storage tank has a drain outlet, the inlet side of which is connected to the drain pipe of the water pump, and the outlet side of which is connected to an external drain pipe.

[0012] The dehumidifier provided by this utility model has the following beneficial effects:

[0013] A water storage tank is formed below the water receiving tray. The water storage tank and the water tank can form a communicating vessel structure, which can significantly increase the storage capacity of condensate. At the same time, a water pump is configured to automatically discharge the condensate in the water storage tank. Due to the existence of the communicating vessel structure, the water tank will be emptied at the same time as the water pump empties the water storage tank. This can effectively reduce the start and stop frequency of the water pump, which is conducive to extending the service life of the water pump. Attached Figure Description

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present utility model or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0031] In the description of this utility model, it should be understood that the directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this utility model. The directional terms "inner" and "outer" refer to the inner and outer contours of each component itself.

[0032] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90° or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0033] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be construed as limiting the scope of protection of this utility model.

[0034] See Figure 1 and Figure 13 As shown, according to an embodiment of the present invention, a dehumidifier is provided, including a chassis 4 and a water receiving tray 1 and a water tank 2 located on the chassis 4. The water receiving tray 1 has a water storage pool 11, and the water storage pool 11 and the water tank 2 are connected in the bottom area to form a communicating vessel structure. The lower the aforementioned bottom area is in principle, the better, so as to ensure that the amount of condensate retained at the bottom of the water storage pool 11 and the water tank 2 is as small as possible. However, the basic principle should be that the physical structure of the connection position between the water storage pool 11 and the water tank 2 is easy to implement. The dehumidifier also includes a water pump assembly (not indicated in the figure), which includes a water pump 31. The inlet of the water pump 31's suction pipe 32 is located in the bottom area of ​​the water storage pool 11. When the water pump 31 is running, it can discharge the condensate stored in the water storage pool 11 to the outside of the dehumidifier. In a preferred embodiment, a filter assembly 321 is assembled at the inlet of the aforementioned suction pipe 32. In one specific embodiment, the water storage tank 11 is integrally formed on the water receiving tray 1. The water receiving tray 1 is positioned below the evaporator (for dehumidification) of the dehumidifier to collect the condensate generated during the operation of the evaporator. The condensate then falls into the water storage tank 11 below the water receiving tray 1, and subsequently into the water tank 2. It is understood that since the water tank 2 and the water storage tank 11 form a communicating vessel structure, to maximize the condensate storage capacity of the communicating vessel structure, the maximum achievable height of the liquid level in the water tank 2 is preferably equal to the maximum achievable height of the liquid level in the water storage tank 11, thus avoiding the disadvantages of the "weakest link" effect.

[0035] In this technical solution, a water storage tank 11 is formed below the water receiving pan 1. The water storage tank 11 and the water tank 2 can form a communicating vessel structure, which can significantly increase the storage capacity of condensate. At the same time, a water pump 31 is configured to automatically discharge the condensate in the water storage tank 11. Due to the existence of the communicating vessel structure, the water tank 2 will be emptied at the same time as the water pump 31 empties the water storage tank 11. This can effectively reduce the start and stop frequency of the water pump 31, which is conducive to improving the service life of the water pump 31.

[0036] In some embodiments, the bottom area of ​​the water tank 2 has a water tank docking mechanism (not labeled in the figure), and the bottom area of ​​the water storage tank 11 has a water storage tank docking mechanism (not labeled in the figure). The water tank 2 and the water storage tank 11 are connected and connected through the water tank docking mechanism and the water storage tank docking mechanism. That is, the water tank 2 and the water storage tank 11 can be connected and connected, so that the water tank 2 can be separated from the water storage tank 11. Specifically, when the condensate water level in the water tank 2 is high, the user can manually separate the water tank 2 from the water storage tank 11 and pour the condensate water into the target area (e.g., the sewer) without using the water pump 31 to pump and drain the water, which reduces energy consumption and can also improve the overall service life of the water pump 31 to a certain extent.

[0037] In some embodiments, a liquid level detection component (not shown or labeled in the figure) is provided in the water tank 2 to detect the real-time liquid level of the condensate in the water tank 2. It should be noted that since the water tank 2 and the water storage tank 11 form a communicating vessel structure, it is not necessary to configure a liquid level detection component in the water storage tank 11 and the water receiving tray 1. Only the liquid level detection component needs to be installed in the water tank 2, which can reduce the use of control materials and thus reduce the product manufacturing cost. In a specific embodiment, the aforementioned liquid level detection component can be a float with a magnet (made of foam, not shown in the figure). The float moves up and down with the water level of the condensate under the buoyancy of the condensate in the water tank 2, thereby realizing the synchronous detection of the condensate water level. At the same time, a corresponding magnetic induction switch (not shown in the figure) is set in the water storage tank 11. When the height of the float corresponds to the position of the magnetic induction switch, the magnetic induction switch will sense the magnet in the float, thereby realizing the real-time detection of the condensate water level. It is understood that if the dehumidifier's drainage function is automatic drainage, the water pump 31 will run and drain under the control of the dehumidifier's control component.

[0038] For details, please refer to [link / reference]. Figures 2 to 8As shown, in some embodiments, the water tank docking mechanism includes a first pair of connecting pipes 21, and the water storage tank docking mechanism includes a second pair of connecting pipes 12. The water tank 2 has a water storage and connection state (corresponding to the dehumidifier operating normally and storing condensate) and a disconnected and emptied state (that is, the water tank 2 and the water storage tank 11 are disconnected, so as to facilitate the user to pour out the condensate in the water tank 2). When the water tank 2 is in the water storage and connection state, the water tank docking mechanism and the water storage tank docking mechanism are connected to each other, and the first pair of connecting pipes 21 and the second pair of connecting pipes 12 are connected inside and outside each other to prevent condensate from flowing out of the water tank 2 and the water storage tank 11. When the water tank 2 is in the disconnected and emptied state, the water tank docking mechanism and the water storage tank docking mechanism are far apart from each other, and the flow of the first pair of connecting pipes 21 and the second pair of connecting pipes 12 is cut off to prevent the condensate in the water tank 2 and the water storage tank 11 from flowing out.

[0039] In some embodiments, the first connecting pipe 21 is equipped with a first on / off valve assembly (not labeled in the figure) and a first ejector structure 22 extending toward the second connecting pipe 12. The water storage tank 11 has a second on / off valve assembly (not labeled in the figure) capable of controlling the on / off of the second connecting pipe 12 and a second ejector structure 13 located in the second connecting pipe 12 and extending toward the first connecting pipe 21. When the water tank 2 is in the water storage connection state, the first ejector structure 22 applies force to the second on / off valve assembly to allow flow through the second connecting pipe 12, and the second ejector structure 13 applies force to the first on / off valve assembly to allow flow through the first connecting pipe 21. In a specific embodiment, the aforementioned first ejector structure 22 and second ejector structure 13 can be rod-shaped bodies, which can be integrally formed with the first connecting pipe 21 or the second connecting pipe 12.

[0040] In this technical solution, by setting corresponding ejector structures on the water tank 2 and the water storage tank 11 to apply force to the first on-off valve assembly and the second on-off valve assembly, the connection of the two connecting pipes can be realized during the docking and connection of the water tank 2 and the water storage tank 11. There is no need to control the on-off state of the two on-off valve assemblies separately, which simplifies the structural design, simplifies the operation, and reduces the design and production costs.

[0041] In one specific embodiment, the first on / off valve assembly includes a first valve stem 231 and a first valve plate 232 fixedly connected to a first end of the first valve stem 231 (e.g., the first valve plate 232 is made of rubber material and is interference-fitted onto the first end of the first valve stem 231). A first support structure 211 is formed within the first connecting pipe 21 (understandably, the first support structure 211 should ensure that the first connecting pipe 21 has a sufficiently large flow area). The first valve stem 231 can be slidably assembled onto the first support structure 211 along the axial direction of the first connecting pipe 21. A first elastic element 233 (e.g., a coil spring) is fitted onto the first valve stem 231. The first elastic element 233 is clamped between the first support structure 211 and the second end of the first valve stem 231. The second ejector structure 13 can apply force to the second end of the first valve stem 231 to overcome the elastic force of the first elastic element 233 and cause the first valve plate 232 to... A flow gap is formed between the pipe opening of the first connecting pipe 21 and the second valve assembly; and / or, the second on / off valve assembly includes a second valve stem 141 and a second valve plate 142 fixedly connected to the first end of the second valve stem 141. A second support structure 121 is formed in the water storage tank 11 (it is understood that the first support structure 211 should ensure that the second connecting pipe 12 has a sufficiently large flow area). The second valve stem 141 can be slidably assembled on the second support structure 121 in a direction parallel to the axial direction of the second connecting pipe 12. A second elastic element 143 (e.g., a helical spring) is fitted on the second valve stem 141. The second elastic element 143 is clamped between the second support structure 121 and the second end of the second valve stem 141. The first ejector structure 22 can apply force to the first end of the second valve stem 141 to overcome the elastic force of the second elastic element 143 so that a flow gap is formed between the second valve plate 142 and the pipe opening of the second connecting pipe 12.

[0042] In this technical solution, the first elastic element 233 and the second elastic element 143 can respectively apply an elastic force to the corresponding valve plate. When the water tank 2 and the water storage pool 11 are not in a connected state (that is, when the two are not assembled in place), the elastic force can ensure that the valve plate reliably seals the corresponding flow port (pipe opening) to prevent the condensate in the corresponding container from flowing out.

[0043] See details Figure 4 and Figure 8 As shown, to ensure reliable engagement between the first elastic element 233 and the second elastic element 143 and their respective valve stems, corresponding stepped holes are formed on the first support structure 211 and the second support structure 121, respectively. (See attached diagram.) Figure 4As shown, the relationships between the stepped hole diameters d1 and d4 on the first support structure 211, the inner diameter d2 and outer diameter d3 of the first elastic element 233, and the diameter d5 of the first valve stem 231 are designed as follows: d1 > d3 > d4 > d2 > d5. This ensures that the first elastic element 233 can be confined between the first support structure 211 and the first valve plate 232. (See Figure 1 for details.) Figure 8 As shown, the relationship between the large aperture d6 of the stepped hole of the second support structure 121, the inner diameter d8 and outer diameter d7 of the second elastic element 143, and the diameter d9 of the second valve stem 142 is designed as follows: d6 > d7 > d8 > d9. The second elastic element 143 is constrained between the second support structure 121 and the first valve plate 232.

[0044] See details Figure 7 As shown, in a specific embodiment, the first valve stem 231 and the second valve stem 141 are arranged parallel to each other at intervals, so that the positional change (sliding) of the two during the docking and assembly of the water tank 2 and the water storage pool 11 is smoother; the second pair of connecting pipes 12 is sleeved on the radial outside of the first pair of connecting pipes 21, and a sealing ring 24 is provided between the first pair of connecting pipes 21 and the second pair of connecting pipes 12 to ensure a good seal between the two pipes.

[0045] In one specific embodiment, the second valve plate 142 and the second valve stem 141 are an integral structure, for example, made by integral rubber injection molding, which simplifies the assembly process and reduces the failure rate; see details. Figure 7 As shown, the second valve plate 142 has an annular groove 1421 on its side facing the second end of the second valve stem 141 for embedding and positioning the second elastic member 143, so as to ensure that the position of the second elastic member 143 is reliable and stable, thereby ensuring smooth switching of the second valve plate 142.

[0046] As another feasible implementation of the second on / off valve assembly, the second on / off valve assembly includes a second valve stem 141 and a second valve plate 142 fixedly connected to the first end of the second valve stem 141 (the two can also be integral). A second support structure 121 is formed in the water storage tank 11. The second valve stem 141 can be slidably assembled on the second support structure 121 in a direction parallel to the axial direction of the second connecting pipe 12. A magnetic attraction assembly is provided between the second valve plate 142 and the opening of the second connecting pipe 12. The first ejection structure 22 can apply force to the first end of the second valve stem 141 to overcome the magnetic attraction force of the magnetic attraction assembly, thereby forming a flow gap between the second valve plate 142 and the opening of the second connecting pipe 12. Of course, the aforementioned first on / off valve assembly can also adopt the aforementioned magnetic attraction assembly. The aforementioned magnetic attraction assembly may specifically include a first magnetic element (positive magnet) and a second magnetic element (negative magnet) that can attract each other, or a magnetic ring and an iron ring. One of them is fixed to the second valve plate 142, and the other is fixedly connected to the port of the second connecting pipe 12, which simplifies the structural design.

[0047] In some embodiments, an installation platform 15 is formed on the outer wall of the top area of ​​the water storage tank 11, and the water pump 31 is assembled on the installation platform 15 by a fixing clip 34. At this time, only the suction pipe 32 and the drain pipe 33 are inside the water storage tank 11, while the water pump 31 is outside the water storage tank 11. This can reduce the protection level requirements for the water pump 31, thereby reducing the cost of product selection.

[0048] The water storage tank 11 has a drain outlet 111. The inlet side of the drain outlet 111 is connected to the drain pipe 33 of the water pump 31, and the outlet side of the drain outlet 111 is connected to an external drain pipe (not shown in the figure). In practical applications, the user can place the outlet of the drain pipe in the discharge area (such as a floor drain) to improve the portability of the dehumidifier. A drainage rib 112 is provided on the top area of ​​the water storage tank 11 to guide the condensate dripping / collected from the evaporator or water tray 1 above into the water storage tank 11, preventing the condensate from dripping directly onto the liquid surface of the water storage tank 11 and causing noise.

[0049] According to an embodiment of the present invention, a drainage control method for a dehumidifier as described above is also provided, comprising the following steps:

[0050] To obtain the dehumidifier's operating mode, generally speaking, dehumidifier operating modes include continuous dehumidification mode (for situations where air humidity is high and long-term dehumidification is required) and non-continuous dehumidification mode.

[0051] When the dehumidifier's operating mode is continuous dehumidification mode, the real-time water level of the condensate stored in the water tank 2 is obtained.

[0052] When the real-time water level of the condensate stored in the water tank 2 reaches the full water level, the water pump 31 is controlled to run and drain for a preset time t0, and then the water pump 31 is controlled to stop running. In a specific embodiment, when the water pump 31 is controlled to run and drain for a preset time t0, the condensate in the water tank 2 is emptied. That is, t0 is the time corresponding to the water pump 31 running at the target speed to empty the condensate in the water tank 2 and the water storage tank 11.

[0053] When the condensate in the water tank 2 reaches the full water level again, the time difference Δt between the time when the condensate in the water tank 2 reaches the full water level again is obtained. Specifically, it can be obtained by recording the difference between the time when the water pump 31 stops running and the time when the water tank 2 reaches the full water level.

[0054] The speed of the water pump 31 is adjusted according to the magnitude of Δt. Specifically...

[0055] When Δt≤t1, it indicates that the time to reach full water is relatively short, meaning the dehumidification capacity is large and the drainage demand is high. Therefore, the water pump 31 is controlled to operate at the first speed (high speed) for drainage; or,

[0056] When t1 < Δt ≤ t2, it indicates that the time to reach full water is neither too short nor too long, and the dehumidification capacity is moderate. Therefore, the water pump 31 is controlled to operate at the second speed (medium speed) for drainage; or,

[0057] When Δt > t2, it indicates that the time to reach the full water state is relatively long, the dehumidification capacity is relatively small, and the drainage demand is relatively low. Therefore, the water pump 31 is controlled to operate at the third speed (low speed) to drain water. The third speed < the second speed < the first speed, where t1 is the reference time for rapid full water filling and t2 is the reference time for slow full water filling.

[0058] In this technical solution, the dehumidification capacity (i.e., the humidity of the environment) is determined by the time it takes for the condensate in the water tank 2 to reach full capacity, and then the water pump 31 is controlled to operate at the corresponding speed to drain water. There is no need to configure a separate detection device, which reduces the design cost.

[0059] In some implementations, when the dehumidifier's operating mode is a non-continuous dehumidification mode, the real-time water level of the condensate stored in the water tank 2 is acquired; when the real-time water level of the condensate stored in the water tank 2 reaches the full water level, a warning message is issued to prompt the user to drain the condensate in the water tank 2. Specifically, the user can choose to remove the water tank 2 from the dehumidifier to empty the condensate or choose to press the corresponding water pump start switch to control the water pump 31 to run and drain the water.

[0060] It will be readily understood by those skilled in the art that, without conflict, the advantageous technical features of the above-mentioned methods can be freely combined and superimposed.

[0061] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model.
