DETAILED DESCRIPTION

[0027] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0028] The condensate drainage structure 100 provided in the application embodiment is mainly used in dehumidifiers to collect condensate generated during the dehumidification process. The structure realizes the free switching of the two drainage modes of water tank storage and continuous external discharge, effectively solving the problem of frequent dumping of traditional dehumidifiers due to the single water tank storage method in high humidity environments, better meeting the needs of different usage scenarios and greatly improving the user experience.

[0029] First, as Figures 1 to 9 As shown, the condensate drainage structure 100 of the embodiment of the present application mainly includes a water holding component 10 and a water tank 20. Specifically, the water holding component 10 is designed as a middle partition of the dehumidifier, which can not only support the core dehumidification components such as the evaporator 200, but also hold the condensate generated during the dehumidification process; and the water tank 20 adopts a pull-out design, which can be installed below the water holding component 10 along the inner and outer sides of the dehumidifier, which is convenient for users to operate.

[0030] Among them, the water holding component 10 is provided with a water outlet 11 connected to the water tank 20 and a drain outlet 12 for connecting to an external drain pipe, which are used to realize the flow direction switching of condensed water between different drainage modes; a water outlet 11 is provided in a water outlet valve 30, and a movable part 40 is movably connected to the water tank 20, and the movable part 40 can move between a first position and a second position to control the opening and closing of the water outlet valve 30. When the movable part 40 is in the first position, the water outlet 11 is opened by the water valve 30, and the water holding component 10 is connected with the water tank 20 through the water outlet 11 to form a first drainage channel 100a; when the movable part 40 is in the second position, the water outlet 11 is sealed by the water valve 30, and the water holding component 10 is connected with the external drain pipe through the drain outlet 12 to form a second drainage channel 100b.

[0031] When doing specific work, such as Figure 3 , Figure 4 , Figure 5 , Fig. 9 As shown, two drainage channels can be formed:

[0032] When the movable part 40 is in the first position and acts on the drain valve 30, when the drain valve 30 opens the drain port 11, the water holding part 10 is connected with the water tank 20 through the drain port 11, and the condensed water directly flows into the water tank 20 for storage. This is suitable for short-term or small-scale dehumidification scenarios, such as bedrooms, study rooms, etc. The user only needs to regularly draw out the water tank 20 and dump it.

[0033] When the movable part 40 is in the second position and does not act on the drain valve 30, the drain valve 30 seals the drain outlet 11, and the condensed water no longer flows to the water tank 20, but flows to the external drain pipe through the drain outlet 12 on the water holding part 10, forming a continuous second drainage channel 100b. This is suitable for scenarios that require long-term continuous dehumidification, such as basements, laundries or factory workshops. It can effectively avoid shutdown problems caused by overfilling the water tank 20, and there is no need to frequently clean the water tank 20, greatly reducing the need for manual maintenance.

[0034] In this way, this structural design not only improves the applicability of the dehumidifier, but also greatly improves the user experience, especially in high humidity environments, completely solving the problem that the water tank of the traditional dehumidifier is easy to fill up and needs to be dumped frequently.

[0035] In some embodiments, Figure 4 , Figure 5 As shown, the drain valve 30 includes an elastic seal 31, an anchor bolt 32 and a spring 33. A guide bracket 34 is provided in the drain port 11. One end of the anchor bolt 32 passes through the guide bracket 34 and can be raised and lowered relative to the guide bracket 34. The elastic seal 31 is fixed to the top end of the anchor bolt 32. The bottom end of the anchor bolt 32 is provided with a stop portion 35 located below the guide bracket 34. The spring 33 is sleeved on the anchor bolt 32, and the two ends of the spring 33 are respectively abutted against the guide bracket 34 and the stop portion 35; when the movable member 40 is in the first position, it abuts against the stop portion 35, and the elastic seal 31 seals the drain port 11. When the movable member 40 is in the second position, it is separated from the stop portion 35, and the elastic seal 31 leaves the drain port 11.

[0036] In this embodiment, the elastic sealing member 31 is a hollow conical sealing sleeve, which is larger at the top and smaller at the bottom. When the movable member 40 is in the first position, the conical surface of the outer side of the conical sealing sleeve is in sealing contact with the opening edge of the top of the drain port 11. When the movable member 40 is in the second position, the conical surface of the outer side of the conical sealing sleeve is spaced from the opening edge of the top of the drain port 11. The conical sealing sleeve can be made of, but not limited to, silicone material.

[0037] In specific implementation, the guide bracket 34 is used as a guide component. When the movable part 40 is located in the first position and applies a force to the stop portion 35, the stop portion 35 drives the anchor bolt 32 to overcome the rebound force of the spring 33, and then pushes the conical sealing sleeve to move upward, thereby releasing its sealing contact with the opening edge of the drain port 11, thereby opening the drain valve 30, and allowing condensed water to flow into the water tank 20 through the drain port 11; and when the movable part 40 is located in the second position and no longer applies a force to the stop portion 35, the rebound force of the spring 33 causes the anchor bolt 32 to shift downward, driving the conical sealing sleeve to reset, and re-close in close contact with the opening edge of the drain port 11, thereby sealing the drain port 11 and closing the drain valve 30. At this time, the condensed water no longer flows into the water tank 20, but flows to the external drain pipe through the drain port 12, thereby realizing a continuous drainage function.

[0038] In some embodiments, the movable member 40 is pivotally connected to the water tank 20. Figure 4 , Figure 5 As shown, the movable member 40 forms a reliable rotation connection with the water tank 20 through the pivot 40a, and the movable member 40 can rotate and move between the first position and the second position, so as to achieve flexible adjustment of the angle, that is, the movable member 40 can rotate between two key positions to selectively control the opening and closing state of the drain valve 30, thereby switching the drainage channel of the condensed water:

[0039] like Figure 7 As shown, the movable part 40 is located in the first position: when the movable part 40 rotates to the vertical state, it contacts the drain valve 30 and exerts a force, thereby opening the drain port 11, and the condensed water flows into the water tank 20 through the first drainage channel 100a, completing the water storage function of the water tank.

[0040] like Figure 8 As shown, the movable part 40 is located in the second position: when the movable part 40 rotates to a horizontal state, it is out of the action range of the drain valve 30. The drain valve 30 can close the drain port 11 under the action of a spring or other elastic structure, and the condensed water enters the second drain channel 100b through the drain port 12, thereby realizing a continuous drainage function.

[0041] For example, when the user needs to switch to the first drainage channel 100a (water storage mode), the user only needs to turn the movable part 40 to a vertical state manually or by external force, so that it can reliably contact the drain valve 30 and apply an opening force; and when it is necessary to switch to the second drainage channel 100b (continuous drainage mode), the user only needs to turn the movable part 40 to a horizontal state to ensure that it is separated from the drain valve 30.

[0042] In addition, in order to meet different installation requirements, in other embodiments, a sliding structure can be used instead of a pivot structure. For example, the movable member 40 is connected to the water tank 20 through a slide rail device, and the movable member 40 slides along the slide rail between two fixed positions: one position contacts the drain valve 30 to open the drain port 11, and the other position is separated from the drain valve 30 to close the drain port 11. This design can not only improve the reliability of the drainage channel switching, but also facilitate the fixing of the movable member 40, thereby reducing the uncertainty of the user during operation.

[0043] In some embodiments, the movable member 40 is installed on the water tank 20 using a hinged structure with damping, that is, the movable member 40 is connected to the water tank 20 with damping rotation. This structural design is intended to prevent the movable member 40 from excessively swinging or rebounding when switching the drainage channel, thereby ensuring that it can accurately stay at the required position, enhancing the stability of the movable member 40 at the predetermined position, and avoiding unexpected position deviations caused by excessive swinging, thereby effectively ensuring the reliable switching of the condensate drainage channel and preventing condensate leakage or incorrect switching of the drainage channel due to the failure of the movable member 40 to accurately position. For example, in a specific implementation, a friction ring can be set on the circumferential surface of the pivot 40a of the hinged structure with damping to provide moderate resistance to prevent the movable member 40 from being too fast or unstable when switching.

[0044] In some embodiments, Figure 4 , Figure 7 As shown, a first protrusion structure 41 pivotally connected to a movable member 40 is provided on the water tank 20, a convex strip 411 is convexly provided on the first protrusion structure 41, the movable member 40 is pivotally connected to the first protrusion structure 41, and when the movable member 40 is pivoted to the first position, it is interference fit with the convex strip 411, and the convex strip 411 stabilizes the movable member 40 in the first position, and the drain valve 30 opens the drain port 11 under the action of the movable member 40.

[0045] In specific implementation, the first protrusion structure 41 serves as the base of the movable part 40 and is connected to the convex strip 411 by an interference fit, ensuring that the movable part 40 can accurately stay at the predetermined first position during rotation to prevent it from being accidentally shifted due to vibration or external force during use. At the same time, through this interference fit, the convex strip 411 can not only stabilize the position of the movable part 40, but also provide obvious tactile feedback when the movable part 40 rotates to a critical position, helping the user to determine whether the correct operation has been completed. One side of the convex strip 411 has an inclined guide surface, and the setting of the guide surface can make the movable part 40 slide more smoothly until it has an interference fit with the convex strip 411; the side of the movable part 40 facing the convex strip 411 is provided with undercuts at intervals, and when the movable part 40 just moves to have an interference fit with the convex strip, the undercuts on the movable part 40 abut against the side of the convex strip, and the setting of such undercuts can prevent the elastic force of the spring 33 from driving the anchor bolt 32 to abut against the movable part 40, so that the movable part 40 rotates from the first position to the second position, that is, the movable part 40 will not automatically rotate downward due to the elastic force of the spring 33; specifically, two undercuts are provided at intervals on the movable part 40. The connection between the two adjacent side surfaces of the first protrusion structure 41 is set as a smooth transition, and the connection between the side surface and the top surface, and the convergence of the two side surfaces and the top surface are all set as a smooth transition.

[0046] That is, in actual use, when the user rotates the movable part 40 to a vertical state, the interference fit between the convex strip 411 and the movable part 40 will produce obvious rotational resistance, which gradually increases during the rotation of the movable part 40 until the movable part 40 is accurately aligned with the predetermined position. This allows the user to intuitively feel whether the movable part 40 is in place by touch during operation, thereby effectively avoiding improper operation or position deviation and ensuring that the sewer valve 30 can be reliably opened or closed.

[0047] In some embodiments, Figure 4 , Figure 7 As shown, the movable member 40 is U-shaped, including a top plate 44 and connecting ears 45 connecting the two ends of the top plate 44, and the two connecting ears 45 are respectively pivoted to the opposite sides of the first protruding structure 41; the top surface of the top plate 44 is convexly provided with an inclined convex rib 43, and the height of the inclined convex rib 43 gradually decreases from the first position to the second position; the movable member 40 acts on the drain valve 30 through the inclined convex rib 43

[0048] With this structural design, when installing the water tank 20, the design of the inclined convex rib 43 allows the movable part 40 to be gradually applied to the drain valve 30 through the inclined surface force, avoiding the possibility of interference and jamming between the movable part 40 and the drain valve 30 caused by severe impact, and making the installation of the water tank 20 smoother, that is, when the user pushes the water tank 20 under the water holding part 10, he can feel the gradual change of force without encountering abrupt changes in resistance, which increases the comfort of operation. In one embodiment, the length-to-height ratio of the inclined convex rib 43 can be set to 2:1. In another embodiment, the length-to-height ratio of the inclined convex rib 43 can be set to 3:2.

[0049] In other embodiments, Figure 5 , Figure 8 As shown, the water tank 20 is further provided with a second protrusion structure 42 arranged opposite to the first protrusion structure 41. The second protrusion structure 42 and the first protrusion structure 41 are spaced apart to form a positioning groove 421 that cooperates with the movable member 40. When the movable member 40 pivots to the second position, the movable member 40 is positioned and matched with the positioning groove 421, and the drain valve 30 seals the drain port 11 under the action of the movable member 40.

[0050] In specific implementation, the connecting ears 45 at both ends of the top plate 44 are connected to the first protruding structure 41 through the pivot 40a, and can rotate freely around the pivot 40a. When the movable part 40 rotates to the second position, the positioning groove 421 precisely cooperates with the movable part 40 to ensure that the movable part 40 stays firmly in the second position. In actual operation, the user can rotate the movable part 40 to a horizontal position until the movable part 40 completely enters the positioning groove 421. At this time, the positioning cooperation between the positioning groove 421 and the movable part 40 provides stable support to ensure that the movable part 40 stays accurately in the predetermined position, effectively preventing the movable part 40 from accidentally shifting due to vibration or external force during use, thereby reducing the risk of noise or failure of drainage channel switching caused by the shaking of the movable part 40.

[0051] In some embodiments, Figure 6 , Figure 7As shown, the water tank 20 includes a box body 21 and a cover body 22 connected to the box body 21, and a movable part 40 is arranged on the cover body 22. The cover body 22 is provided with a water guide structure 23 for guiding condensed water into the box body 21. With this structural design, the cover body 22 is a detachable component, which is convenient for users to easily access the inside of the box body 21, so that the accumulation of condensed water or cleaning of the box body 21 can be conveniently checked, which significantly reduces the complexity of maintenance. At the same time, the movable part 40 is arranged on the cover body 22, which can effectively reduce the complex structure inside the box body 21 and improve the utilization efficiency of the internal space of the box body 21. When necessary, the user can disassemble the movable part 40 together with the cover body 22, which further simplifies the operation process and maintenance work. In addition, a water guide structure 23 (such as a water guide groove, etc.) can be designed on the cover body 22 to ensure that the condensed water can flow smoothly into the box body 21, that is, the design of the water guide structure 23 ensures that the guiding path of the condensed water is clear and efficient.

[0052] In some embodiments, Fig. 9 As shown, a drain hole 13 is provided on the water holding part 10, and the water inlet position of the drain hole 13 is higher than the water inlet position of the drain port 12. With this design, when the drain port 11 is sealed by the drain valve 30, for example, during the dehumidification process of the evaporator 200, the amount of condensed water generated may be greater than the discharge capacity of the drain pipe connected to the drain port 12, or when the drain pipe connected to the drain port 12 is blocked, the overflowed condensed water can flow to the cover body 22 below through the drain hole 13, and then the condensed water flows smoothly into the box body 21 along the water guide structure 23 on the cover body 22, so as to ensure that when the drainage is abnormal, the condensed water can be effectively guided to the inside of the water tank 20, thereby avoiding the risk of condensed water overflowing or equipment damage.

[0053] In some embodiments, the condensate drainage structure further includes a manual drive device, through which the movable member 40 switches between the first position and the second position. A water outlet plug may be provided at the drain port 12, and when continuous drainage is required, the water outlet plug is pulled out from the drain port 12. The manual drive device may adopt a rod-type drive structure, one end of which is connected or linked to the movable member 40 to drive the movable member 40 to rotate around the first protruding structure 41 to switch between the first position and the second position, and the other end of the rod passes through the water tank 20 and is exposed to form an operating end for manual operation. The top surface of the second protruding structure 42 may be provided with a recess 422 adapted to the driven rod.

[0054] In some embodiments, an electric drive device (not shown) is also included, and the movable part 40 selectively acts on the drain valve 30 under the drive of the electric drive device to seal or open the drain port 11. In this embodiment, the electric drive device (such as a motor) drives the movable part 40 so that it can selectively act on the drain valve 30 to achieve the sealing or opening of the drain port 11, that is, through the drive of the electric drive device, the movable part 40 can automatically control the opening and closing of the drain valve 30, without the user manually adjusting the drainage mode, thereby greatly improving the convenience of the device and saving the user's time and energy. In addition, the electric drive device provides precise control to ensure that the movable part 40 can accurately reach the predetermined position when needed, triggering the opening or sealing operation of the drain valve 30. This precise control reduces errors in manual operation and avoids improper drainage mode switching or condensate leakage caused by human factors, thereby ensuring efficient and stable operation of the equipment.

[0055] In the second aspect, the embodiment of the present application provides a dehumidifier, including the condensate drainage structure 100 of any embodiment of the first aspect. Those skilled in the art can clearly understand that for the convenience and simplicity of description, the specific working process of the dehumidifier described above can refer to the corresponding process in the aforementioned embodiment of the condensate drainage structure 100, and will not be repeated here.

[0056] When the movable part 40 is driven by an electric drive device, the dehumidifier also includes a humidity sensor and a controller. The humidity sensor and the electric drive device are electrically connected to the controller. The controller is configured to control the electric drive device to drive the movable part 40 to act on the drain valve 30 to seal the drain port 11 when the humidity sensor detects that the humidity of the background environment of the dehumidifier is greater than a preset threshold.

[0057] In this embodiment, the humidity sensor is installed on the dehumidifier to detect the humidity of the current environment in real time and transmit the measurement results to the controller. The controller is electrically connected to the electric drive device. When the humidity sensor detects that the ambient humidity is greater than a preset threshold, the controller will send a signal to control the electric drive device to drive the movable part 40 to act on the drain valve 30, thereby sealing the drain port 11 and allowing condensed water to flow into the water tank 20.

[0058] In actual use, when the dehumidifier works in an environment with high humidity, the humidity sensor continuously monitors the humidity change and feeds back to the controller. When the humidity is lower than the set threshold, the controller automatically drives the movable part 40 through the electric drive device to seal the drain port 11, start the water tank storage mode, and store the condensed water in the water tank 20. When the humidity exceeds the set threshold, it means that the dehumidification amount is large. At this time, the controller opens the drain port 11 through the electric drive device to achieve continuous discharge of condensed water, avoid overflowing the water tank, and ensure efficient operation of the equipment. Therefore, the user does not need to worry about whether the equipment switches the drainage mode on time. The dehumidifier will automatically adjust according to the ambient humidity, reducing the user's manual operation requirements, making the use of the equipment more convenient, and further improving the user's experience.

[0059] The condensate drainage structure and dehumidifier provided in the present embodiment realize the switching of drainage modes by arranging a drain port and a water outlet on the water holding component and controlling the opening and sealing status of the drain valve through movable parts, combined with a simple and reliable mechanical structure, without the need for a complex control system, and the structure has a small number of parts, simple assembly and low production cost; the user only needs to perform a simple manual operation to switch the drainage mode, without the need to disassemble or replace parts, and can freely select the water tank water storage mode or the continuous drainage mode according to the use environment to meet the needs of different usage scenarios.

[0061] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components.
