Description

Technical Field

[0001] The present invention belongs to the technical field of dehumidifiers, and particularly relates to a water tank structure of a dehumidifier, a dehumidifier, and a control method. Background Art

[0002] Existing dehumidifiers usually come with water tanks of fixed capacity, whose volume design is relatively fixed and difficult to meet the needs of different usage scenarios. In high-humidity environments, due to the limited capacity of the water tank, users need to frequently pour out the accumulated water, which is inconvenient to use; especially when the water tank is full, due to its large weight, users need to be careful during the process of pouring water to avoid spilling, increasing the difficulty of use. In addition, the design of the traditional fixed-capacity water tank occupies a large amount of space in the body of the device, affecting the compactness and portability of the equipment. At the same time, the design of the fixed-capacity water tank results in a relatively large overall volume of the machine, occupying more space during transportation and storage, and increasing the transportation and storage costs. Therefore, how to optimize the water tank design while ensuring the dehumidification function, improving the usability, space utilization rate, and transportation efficiency of the dehumidifier has become an urgent problem to be solved.

[0003] Due to the fact that the water tank of the dehumidifier in the prior art has a fixed-capacity structure, resulting in problems such as a relatively large volume of the dehumidifier and increased transportation and storage costs, the present invention has been researched and designed to provide a water tank structure of a dehumidifier, a dehumidifier, and a control method.

[0044] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. The following description of at least one exemplary embodiment is actually illustrative only and in no way restricts the present invention and its application or use. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0045] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by orientation words such as "front, rear, upper, lower, left, right", "transverse, vertical, perpendicular, horizontal" and "top, bottom" is usually based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present invention and simplifying the description. Without contrary description, these orientation words do not indicate and imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the protection scope of the present invention; the orientation words "inside, outside" refer to the inside and outside relative to the contour of each component itself.

[0046] For the convenience of description, spatial relative terms such as "above...", "above...", "on the upper surface of...", "above" can be used here to describe the spatial positional relationship between a device or feature shown in the figure and other devices or features. It should be understood that the spatial relative terms are intended to include different orientations in use or operation in addition to the orientation described in the figure of the device. For example, if the device in the drawing is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "beneath other devices or structures" afterwards. Thus, the exemplary term "above..." can include both the orientation of "above..." and "below...". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and corresponding explanations should be made for the spatial relative descriptions used here.

[0047] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. Without additional statements, the above terms have no special meaning, so it should not be construed as a limitation on the protection scope of the present invention.

[0048] Referring to Figures 1-5 As shown, according to an embodiment of the present invention, a water tank structure of a dehumidifier is provided, including: a body 1, a base 2 is provided at the bottom of the body 1, at least part of the base 2 and the body 1 enclose a cavity structure, the opening of the cavity structure is located on the body 1, a water tank 3 is provided on the base 2, along the opening direction of the cavity structure, the length of the base 2 can be adjusted to change the volume of the water tank 3.

[0049] In this technical solution, when the dehumidifier is in a non-working mode, the length of the base 2 can be adjusted to reduce the volume of the water tank 3, so that the water tank 3 is embedded in the body 1, reducing the occupied space of the dehumidifier body 1. When the dehumidifier is working, the length of the base 2 can be adjusted according to the real-time state of the dehumidifier, so as to adjust the volume of the water tank 3 to meet the needs of the dehumidifier, improving the convenience of use, space utilization rate and transportation efficiency of the dehumidifier.

[0050] In a specific embodiment, the water tank 3 is detachably connected to the base 2, which is convenient for the user to take out the water tank 3 for drainage.

[0051] In some embodiments, the base 2 includes a fixed chassis 4 and a separated base 5. Along the opening direction of the cavity structure, a guide rail 7 is provided at the bottom of the fixed chassis 4, at least part of the separated base 5 is located in the guide rail 7, and the separated base 5 can move along the guide rail 7 to adjust the length of the base 2.

[0052] In this technical solution, a guide rail is provided at the bottom of the base 2, at least part of the separated base 5 is located in the guide rail 7, and the separated base 5 can move along the guide rail 7 to adjust the length of the base 2, and further adjust the volume of the water tank 3. It should be noted that the fixed chassis 4 is clamped with the bottom of the body 1, the opening of the cavity structure can be provided on the front side of the body 1, and the separated base 5 moves along the direction from the rear side to the front side of the body 1 to adjust the length of the base 2.

[0053] In some embodiments, a rack is provided on the separated base 5, a driving member 9 is provided on the side wall of the guide rail 7, a gear is provided on the driving shaft of the driving member 9, and the gear meshes with the rack.

[0054] In this technical solution, through the cooperation of the gear and the rack, the relative movement between the separation base 5 and the fixed chassis 4 is realized, and the forward and reverse states of the driving member 8 are adjusted, so as to adjust the increase or decrease of the length of the base 2, so that the volume of the water tank 3 changes.

[0055] In a specific embodiment, the guide rail 7 can be formed into a groove structure, the separation base 5 extends in from the opening of the groove structure, and the driving member 9 can be arranged on the inner wall or the outer wall of the guide rail 7. When it is arranged on the outer wall of the guide rail 7, through holes are arranged on the side wall of the guide rail 7, and the driving shaft of the driving member 9 extends into the guide rail 7. The driving member 9 can adopt a motor.

[0056] In a specific embodiment, a limiting portion can be arranged on the rack to prevent the rack from separating from the gear and avoid the separation of the fixed chassis 4 and the separation base 5; alternatively, a first limiting portion can be arranged on the inner wall of the guide rail 7, and a second limiting portion can be arranged on the separation base 5. The second limiting portion is located at one end of the separation base 5 extending into the guide rail 7. Through the cooperation of the first limiting portion and the second limiting portion, the rack is prevented from separating from the gear and the separation of the fixed chassis 4 and the separation base 5 is avoided.

[0057] In the water tank structure of the dehumidifier of the present invention, when the dehumidifier is in a non-working state and the water tank is empty, the electric gear rotates to drive the separation chassis to slide along the slide rail towards the fixed chassis, and at the same time, the folding water tank front cover is driven by the separation chassis to fold and store towards the water tank rear plate. When in the working state, the electric gear rotates in reverse, the separation chassis slides along the slide rail in the opposite direction of the fixed chassis, and at the same time, the folding water tank is unfolded.

[0058] The water tank structure of the dehumidifier of the present invention aims to solve the problems of inconvenient use, large space occupation and high transportation cost existing in the design of the traditional dehumidifier water tank.

[0059] In some embodiments, a plurality of casters 6 are arranged on the bottom surfaces of the fixed chassis 4 and the separation base 5, and a plurality of support members 19 are arranged on the top surfaces of the fixed chassis 4 and the separation base 5.

[0060] In this technical solution, by arranging a plurality of casters 6 on the bottom surfaces of the fixed chassis 4 and the separation base 5, while the casters 6 play a supporting role for the dehumidifier, they also facilitate the movement of the dehumidifier and the relative movement between the fixed chassis 4 and the separation base 5. By arranging a plurality of support members 19 on the top surfaces of the fixed chassis 4 and the separation base 5, the support members 19 can adopt elastic materials such as rubber to avoid violent collision between the body 1, the water tank 3 and the base 2, resulting in damage to the dehumidifier.

[0061] The top surfaces of the fixed chassis 4 and the separation base 5 refer to the sides of the fixed chassis 4 and the separation base 5 facing the fuselage 1, and the bottom surfaces of the fixed chassis 4 and the separation base 5 refer to the sides of the fixed chassis 4 and the separation base 5 facing the ground.

[0062] In some embodiments, a second buckle 10 is provided on the top surface of the fixed chassis 4, a first buckle 8 is provided on the top surface of the separation base 5, one end of the water tank 3 is engaged with the second buckle 10, and the other end of the water tank 3 is engaged with the first buckle 8.

[0063] In this technical solution, both ends of the water tank 3 are fixed by the second buckle 10 and the first buckle 8, which facilitates the installation and disassembly of the water tank 3.

[0064] In some embodiments, the water tank 3 includes a front cover 11, a box body 14 and a rear cover 12. One end of the box body 14 is connected to the front cover 11, and the other end of the box body 14 is connected to the rear cover 12. The front cover 11 is snap-connected to the first buckle 8, and the rear cover 12 is snap-connected to the second buckle 10. The box body 14 is a foldable box body.

[0065] In this technical solution, the box body 14 has a cylindrical structure and is foldable, eliminating the need to worry about water spraying problems and improving the safety and convenience of the pouring operation. Preferably, the box body 14 is made of a lightweight silicone film, and both ends of the box body 14 are sealed and fixed by the front cover 11 and the rear cover 12, so that the water tank 3 can be detachably installed on the base 2.

[0066] It should be noted that when the length of the base 2 is the minimum length, that is, when the volume of the water tank 3 is the minimum volume, the side of the front cover 11 facing away from the rear cover 12 is in the same plane as the surface of the fuselage 1.

[0067] In some embodiments, a water inlet 13 is provided on the rear cover 12 for allowing the water of the dehumidifier to flow into the box body 14, and a drain port 15 is provided on the front cover 11 for draining the water in the box body 14.

[0068] In this technical solution, when the water tank 3 is installed on the base 2, the water inlet 13 is communicated with the drain port inside the fuselage 1, so as to drain the water in the dehumidifier into the water tank 3. Further, a sealed water plug can be provided at the water inlet 13. When the water inlet 13 is communicated with the drain port inside the fuselage 1, the sealed water plug aligns with the protrusion on the drain port of the dehumidifier fuselage, and the sealed water plug is pushed open, and the condensate water of the dehumidifier enters the water tank therefrom. When the water inlet 13 is disconnected from the drain port inside the fuselage 1, the sealed water plug is closed to avoid the problem of water spraying from the water tank 3.

[0069] In some embodiments, an air inlet 18 is provided on the front cover 11, and the air inlet 18 is connected to the space of the box body 14. A sensor 16 and a handle 17 are provided on the side of the front cover 11 facing away from the rear cover 12. The sensor 16 is used to detect the distance between the water tank and the nearest obstacle. A water level sensor is provided in the box body 14.

[0070] In this technical solution, in order to prevent the completely sealed water tank 3 from being unable to be folded and unfolded smoothly due to pressure problems, an air inlet 18 is provided on the front cover 11 to allow air to enter the water tank 3 to balance the pressure, and the water tank can be taken out by the handle. The sensor 16 and the water level sensor can prevent the water tank 3 from being over-expanded to occupy space or cause damage, and the optimal volume of the water tank 3 can also be calculated according to the water level change. Preferably, the sensor 16 is an infrared sensor, and the water level sensor can be a water level float.

[0071] Preferably, an air inlet hole 18 is provided on the top of the front cover 11 to prevent water in the water tank 3 from spilling out from the air inlet hole 18 .

[0072] In the dehumidifier water tank structure of the present invention, the folding water tank is composed of a front cover, a rear plate, and a box body. The front cover is provided with a water tank handle, a drain plug, an air inlet hole, a chassis buckle, and an infrared sensor. The folding box body adopts a lightweight silicone film. The rear plate box body is provided with a sealed water plug and a chassis buckle, and a water level float is provided in the box body. The sealed water plug is used to inlet water. When the rear plate of the water tank is placed on the fixed chassis, the water inlet of the sealed water plug is aligned with the protrusion on the drain outlet of the dehumidifier body, and the sealed water plug is pushed open, and the condensed water of the dehumidifier enters the water tank. When the user needs to pour water, the water tank is lifted away, and the sealed water plug is closed, which greatly reduces the risk of water spillage in the water tank. However, due to the pressure problem, the completely sealed water tank cannot be folded and unfolded smoothly, so an air inlet hole is provided on the top of the front cover of the water tank to allow air to enter and balance the pressure. There is no risk of water leakage when it is set at this position. A drain port is provided under the front cover of the water tank, and the water can be directly drained without lifting the water tank. The tank body is made of lightweight materials and the water tank handle is external, which makes it easier for users to lift the water tank and pour water, reducing physical exertion. At the same time, users can manually adjust the size of the foldable water tank through the handle to meet the needs of different users. The infrared sensor set on the water tank can sense the distance to the nearest obstacle, and the water level float can sense the change of water level height. Inputting this information into the controller can prevent the water tank from over-expanding and occupying space or causing damage, and can also calculate the optimal water tank volume according to the water level change.

[0073] It should be noted that the sealing structure of the sealing water plug in the water tank structure of the dehumidifier can be realized by structures such as a spring-type sealing water plug / a check valve / a one-way silica gel sheet, etc. Setting a one-way silica gel sheet at the water plug at the water inlet of the water tank is the simplest and most effective solution among them, and the elasticity of the silica gel sheet can be used to achieve the one-way flow of water and automatic sealing. The following is the specific working process:

[0074] The silica gel sheet is located inside the water tank at the water inlet of the sealing water plug, with the upper end fixed and the lower end movable.

[0075] In the initial state, the silica gel sheet closely adheres to the water inlet to prevent the water in the water tank from flowing back or leaking.

[0076] When the water tank is installed on the dehumidifier, the drain port of the dehumidifier pushes open the silica gel sheet, the sealing water plug is opened, and the water flows into the water tank along the water inlet of the water tank.

[0077] When the water tank is taken out to pour water, due to the water pressure inside the water tank and the elasticity of the silica gel sheet itself, the silica gel sheet rebounds to the closed position, and the water plug is resealed to prevent the water in the water tank from leaking from the water inlet when the user pours water.

[0078] The prior art discloses a dehumidifier, which reduces the volume of the machine body and increases the volume of the water tank by placing the water tank outside. When in the idle state, the dehumidifier body is stored in the water tank, and when in the working state, the body is placed above the water tank, thereby reducing the storage space and increasing the water storage volume. However, the patent still has the following deficiencies:

[0079] 1. When switching to the working state, it is necessary to lift the relatively heavy body, which increases physical exertion and potential safety hazards;

[0080] 2. When pouring water, it is necessary to lift the body and place it beside, which is inconvenient to operate in a room with limited space;

[0081] 3. The water tank still has a fixed volume and cannot be adjusted according to the actual use space and dehumidification rate.

[0082] The water tank structure of the dehumidifier of the present invention can be folded and stored in the body of the dehumidifier when the dehumidifier is in a non-working mode, occupying little space in the body of the dehumidifier; it improves the portability and space utilization rate of the device, increases the container loading capacity during transportation, and reduces logistics and warehousing costs. It can not only optimize the overall volume through the foldable water tank design, but also improve transportation and warehousing efficiency. When the dehumidifier is in the working mode, the water tank unfolds with the detachable chassis, and the volume of the water tank can be adjusted manually and automatically. Preferably, the water tank intelligently adjusts its volume according to the user's space and dehumidification rate and unfolds to store water. Further, when in the working state, the unfolding degree of the water tank can be adjusted according to the dehumidification space and dehumidification rate of the dehumidifier to control the volume of the water tank to meet the needs of customers in different usage scenarios. The water inlet of the water tank adopts a closed water plug design, and the box body is made of lightweight silicone material. When the user pours water, they only need to directly lift the water tank to pour water, which is convenient to operate and there is no need to worry about water spillage and safety issues. The water tank adopts lightweight materials and a sealed water tank design, which not only reduces the weight of the device, but also significantly improves the portability and use safety of the dehumidifier, thus significantly enhancing the user experience. The user can directly lift the water tank to perform the pouring operation without worrying about water spillage, further improving the safety and convenience of the pouring operation and significantly enhancing the user experience.

[0083] The present invention also provides a dehumidifier, including the above-mentioned water tank structure of the dehumidifier.

[0084] Combined with referring to Figure 6 As shown, in some embodiments, the present invention also provides a control method for the above-mentioned dehumidifier, which is specifically implemented according to the following steps:

[0085] A judgment step, judging the relationship between the water level in the water tank 3 and the current capacity of the water tank 3;

[0086] A control step, when the water level in the water tank 3 is less than 20% of the current capacity of the water tank 3, controlling the length of the base 2 to be adjusted to the minimum length so that the water tank 3 is in the minimum volume state;

[0087] When the water level in the water tank 3 is not less than 20% of the current capacity of the water tank 3, controlling the length of the base 2 according to the distance between the dehumidifier and the nearest obstacle.

[0088] The dehumidifier is powered on, and the controller is initialized. The infrared sensing device on the front cover 11 of the water tank 3, the float sensor in the water tank 3, and the humidity sensor on the body of the dehumidifier are started. The infrared sensing device detects the distance to the obstacle in front of the water tank in real time to judge the available space size; the water tank float sensor monitors the water level change in real time; the humidity sensor monitors the humidity change in the space in real time. It is set that there is a certain proportional relationship between the maximum capacity when the folding water tank 3 is fully unfolded and the minimum capacity when it is fully folded. When the float detects that the water level in the water tank is less than 20% of the current capacity when powered on, if the water tank 3 is in the unfolded state at this time, the controller fully folds the water tank 3 to the minimum capacity through the electric gear. If the water tank 3 is already fully folded at this time, it maintains this state. After the operation of the minimum capacity state of the water tank 3 is completed, the controller enters the determination of the space threshold and the dehumidification rate.

[0089] It should be noted that the current capacity is the capacity of the water tank 3 in the real-time state. The capacities in the folded / unfolded / half-folded states are all different. After powering on, the water tank 3 is not necessarily in the folded state. It may also be unfolded. Judging according to the current capacity can take into account the actual situation.

[0090] In some embodiments, controlling the length of the base 2 according to the distance between the dehumidifier and the nearest obstacle further includes the following steps:

[0091] When the distance S between the dehumidifier and the nearest obstacle is less than the preset distance, control the base 2 to remain unchanged, and the volume of the water tank 3 remains unchanged. When the distance S between the dehumidifier and the nearest obstacle is not less than the preset distance, control the length of the base 2 according to the dehumidification rate of the dehumidifier.

[0092] When the float detects that the water level in the water tank is greater than 20% of the current capacity when powered on, directly enter the determination of the space threshold and the dehumidification rate.

[0093] When the infrared sensing detects that the distance between the front cover of the water tank and the obstacle is too small, and the signal processing result of the controller is that the space threshold S < S1, the space threshold S1 is related to whether the dehumidification space meets the requirement for the water tank to be fully unfolded. The water tank remains unchanged and does not continue to unfold or fold.

[0094] When the infrared sensing detects that there is a certain distance between the front cover of the water tank and the obstacle, meeting the requirement for the water tank to unfold, and the signal processing result of the controller is that the space threshold S ≥ S1, at this time, enter the determination of the dehumidification rate.

[0095] The space threshold S1 is the distance space required to fully unfold the water tank.

[0096] In some embodiments, controlling the length of the base 2 according to the dehumidification rate of the dehumidifier further includes the following steps:

[0097] A judgment step for judging the relationship between the current dehumidification rate R of the dehumidifier and the preset dehumidification rates R1 and R2, where R1 is less than R2;

[0098] A control step. If R > R1, control the length of the base 2 to be adjusted to the maximum length so that the water tank 3 is in the maximum volume state;

[0099] When R2 ≤ R ≤ R1, control the length of the base 2 to be adjusted so that the volume of the water tank 3 is 80% of the maximum volume of the water tank 3;

[0100] If R < R2, control the base 2 to remain as it is and the volume of the water tank 3 remains unchanged.

[0101] The water tank float monitors the water level change speed in real time, combines with the environmental humidity change data, and calculates the current dehumidification rate R. According to the magnitude of the dehumidification rate R, the controller judges the water tank capacity requirement:

[0102] If R > R1, it means the dehumidification rate is extremely high. It is predicted that a large-capacity water tank is needed, and the water tank is fully expanded to increase the water storage capacity.

[0103] If R2 ≤ R ≤ R1, it means the dehumidification rate is moderate. It is predicted that a medium-capacity water tank is needed, and the water tank is expanded / folded to 80% of the maximum capacity, appropriately increasing the water storage capacity.

[0104] If R < R2, it means the dehumidification rate is relatively low, and the water tank remains unchanged to maintain the current water storage capacity.

[0105] It should be noted that R = (r1 - r2) / (t2 - t1), where r1 and r2 are the environmental humidities at time t1 or t2.

[0106] In some embodiments, after the length of the base 2 is adjusted and the volume 3 of the water tank 3 meets the requirements, the following steps are further included;

[0107] A judgment step for judging the relationship between the current water level in the water tank 3 and the current volume of the water tank 3;

[0108] A control step. When the current water level in the water tank 3 reaches 78% of the current capacity of the water tank 3, control the dehumidifier to enter the full-water shutdown state and remind the user to pour out the water;

[0109] If the current water level in the water tank 3 has not reached 78% of the current capacity of the water tank 3, control the dehumidifier to continue working until the current water level in the water tank 3 reaches 78% of the current capacity of the water tank 3, and then control the dehumidifier to enter the full-water shutdown state and remind the user to pour out the water.

[0110] In some embodiments, when the current water level in the water tank 3 has not reached 78% of the current capacity of the water tank 3, the following steps are further included:

[0111] A judgment step of judging whether the dehumidifier is moved or whether the obstacle in front of the water tank 3 is removed;

[0112] A control step of, when the dehumidifier is moved by a person or the obstacle in front of the water tank 3 is removed, controlling the length of the base 2 according to the distance between the dehumidifier and the nearest obstacle.

[0113] When the dehumidifier is not moved or the obstacle in front of the water tank 3 is not removed, it is detected whether the current water level in the water tank 3 reaches 78% of the current capacity of the water tank 3. When the current water level in the water tank 3 reaches 78% of the current capacity of the water tank 3, the dehumidifier is controlled to stop due to full water, and the user is reminded to pour out the water.

[0114] After the water tank capacity state is stable, the controller continues to detect the signal. When the water level reaches 78% of the current water tank capacity, the dehumidifier stops due to full water, and the user is reminded to pour out the water.

[0115] If the water level has not reached 78%, but the dehumidifier is moved by a person or the obstacle in front of the water tank is removed, the space where the dehumidifier is located may change, then the judgment of the space threshold is re-entered.

[0116] If the water level has not reached 78%, and the machine is not moved or the obstacle in front of the water tank is not removed, and the space where the dehumidifier is located does not change, then wait until the water level reaches 78%, and the dehumidifier stops due to full water.

[0117] Through the above control logic, the dehumidifier can intelligently adjust the water tank capacity according to the actual use environment, such as the space size and the dehumidification rate. It can expand the water tank capacity when the dehumidification demand is high, solving the problem of users pouring water frequently. Also, when the use space is limited or the dehumidification demand is not large, it can avoid the waste of water tank capacity or the problem of excessive space occupation, significantly improving the use convenience and space utilization rate of the device. At the same time, it can detect the change of the space where the dehumidifier is located in real time, such as the user moving the device or the removal of the obstacle, and adjust the water tank capacity, further optimizing the user experience.

[0118] The control method of the dehumidifier of the present invention, through the automatic adjustment control logic of the water tank volume, dynamically adjusts the water tank volume according to the actual humidity environment and the dehumidification rate, reducing the frequency of users pouring water and improving the use convenience. When the dehumidifier is in a non-working state, the water tank is in a fully folded state. When in the working state, the unfolding degree of the water tank can be adjusted according to the dehumidification space and the dehumidification rate of the dehumidifier, controlling the water tank volume to meet the needs of customers in different use scenarios.

[0119] It is easy for those skilled in the art to understand that, on the premise of no conflict, the advantageous technical features of the above various methods can be freely combined and superimposed.

The above is only the preferred implementation manner of the present invention.
