Technical Field

[0001] The invention belongs to the technical field of air conditioning, and in particular relates to a dehumidifier and a control method thereof. Background Art

[0002] With the continuous improvement of people's living standards, dehumidifiers have gradually become an indispensable product in people's families. The dehumidification principle of a dehumidifier is to suck high-humidity air into the heat exchanger, which is converted into dry air through heat exchange, and then discharged into the room. The generated condensed water gathers and flows into the water tank. At present, the water tanks of dehumidifiers on the market are mostly pulled out of the placement cavity of the dehumidifier body in a horizontal manner to pour out the condensed water collected in the water tank. After that, the user assembles the water tank in the placement cavity to achieve reset. However, there is a phenomenon that the water tank is not reset properly, causing the dehumidifier to misjudge the machine damage. Summary of the invention

[0003] Therefore, the present invention provides a dehumidifier and a control method thereof, which can overcome the technical problem in the prior art that the dehumidifier water tank cannot be fully reset when it is assembled and reset after the condensed water in the water tank is poured out.

[0004] In order to solve the above problems, the present invention provides a dehumidifier, including a dehumidifier body and a water tank, the dehumidifier body including a rear side vertical plate, the rear side vertical plate having an opening corresponding to the placement cavity of the dehumidifier body, a bottom of the placement cavity is provided with a base, the water tank includes a box body, the box body is assembled in the placement cavity through the opening and is located on the base, a guide plate is provided on the outer edge of the base corresponding to the opening, the guide plate has a water tank anti-detachment state, when the guide plate is in the water tank anti-detachment state, the guide plate can be driven to rotate along a first rotation direction close to the outer side wall of the water tank and finally abut against the outer side wall of the box body.

[0005] In some embodiments, the guide plate also has a water tank pulling state. When the guide plate is in the water tank pulling state, the guide plate can rotate along a second rotation direction following the movement of the box body, and always contacts the outer wall or bottom wall of the box body during rotation, until the water tank is separated from the chassis, and the guide plate rotates along the second rotation direction to a horizontal state, and the second rotation direction is opposite to the first rotation direction.

[0006] In some embodiments, a rotation driving component is provided on the chassis, and the rotation driving component is used to drive the guide plate to rotate forward or reversely to achieve the switching of the guide plate between the water tank anti-detachment state and the water tank pulling state.

[0007] In some embodiments, the water tank further comprises a handle hinged to the top of the tank body, the water tank having a water collecting state assembled in the placement cavity and a water pouring state outside the placement cavity, the tank body having an outer wall, when the water tank is in the water collecting state, the handle is horizontally supported by the top surface of the outer wall, and the outer side surface of the handle does not protrude from the wall surface of the outer wall, the outer wall has a hand-gripping groove recessed toward the inner side of the placement cavity, and a finger-passing gap is formed between the inner side surface of the handle and the inner groove wall of the hand-gripping groove.

[0008] In some embodiments, the outer side surface of the handle, the wall surface of the outer side wall of the box body, and the rear wall surface of the rear vertical plate are on the same vertical plane.

[0009] In some embodiments, the upper edge of the opening has a horizontal plate extending horizontally toward the inner side of the placement cavity, and the horizontal plate is located on the rear vertical plate. A plurality of position detection sensors are arranged on the bottom surface of the horizontal plate. When the water tank is in the water collecting state, the dimension of the handle in the direction of pulling the water tank horizontally outward is defined as its width, and a plurality of the position detection sensors are arranged at intervals along the width, and the projections of each position detection sensor in the vertical downward direction are all within the width range.

[0010] In some embodiments, a finger holding groove is formed on the top surface of the handle close to the placement cavity, and the finger holding groove is connected to the hand picking groove to ensure that the operator's fingers can extend into the finger holding groove through the hand picking groove and the finger passing gap.

[0011] The present invention also provides a control method for the dehumidifier as described above, comprising the following steps:

[0012] Obtaining real-time location information of the water tank and obtaining control instructions of the dehumidifier;

[0013] According to the real-time position of the water tank and the control instruction, the rotation of the guide plate is controlled so that the guide plate can be switched between the water tank anti-slip state and the water tank pulling state.

[0014] In some embodiments, when a position detection sensor is included, there are three position detection sensors, each of which is arranged at intervals along the width direction of the handle, and according to the real-time position of the water tank and the control instruction, controlling the rotation of the guide plate so that the guide plate can switch between the water tank anti-detachment state and the water tank pulling state specifically includes:

[0015] When the control instruction is a water tank reset instruction, the handle is detected by two position detection sensors located on the inner side and the outer side of each position detection sensor. When both the inner and outer position detection sensors detect the handle, the guide plate is controlled to be at a position forming a first angle a1 with the horizontal plane so that the guide plate is in an anti-detachment state of the water tank; when the inner position detection sensor does not detect the handle and the outer position detection sensor detects the handle, the guide plate is controlled to be at a position forming a second angle a2 with the horizontal plane; when both the inner and outer position detection sensors do not detect the handle, the guide plate is controlled to be at a position forming a third angle a3 with the horizontal plane, wherein a1>a2>a3; or,

[0016] When the control instruction is a water tank pulling instruction, the handle is detected by each of the position detection sensors. When each of the position detection sensors detects the handle, the guide plate is controlled to be at a position forming a fourth angle a4 with the horizontal plane; when the inner position detection sensor does not detect the handle and the remaining position detection sensors all detect the handle, the guide plate is controlled to be at a position forming a fifth angle a5 with the horizontal plane; when the outer position detection sensor detects the handle and the remaining position detection sensors do not detect the handle, the guide plate is controlled to be at a position forming a sixth angle a6 with the horizontal plane; when none of the position detection sensors detects the handle, the guide plate is controlled to be at a position forming a seventh angle a7 with the horizontal plane, a4>a5>a6>a7.

[0017] In some embodiments, when the control instruction is a water tank pulling instruction, a child lock instruction configured for the dehumidifier is also obtained. When the child lock instruction is obtained, the guide plate is controlled to be at a position forming a first angle a1 with the horizontal plane so that the water tank is in the water tank anti-detachment state; when the child lock instruction is not obtained, the guide plate is controlled to be at a position forming a fourth angle a4 with the horizontal plane.

[0018] The dehumidifier and control method thereof provided by the present invention have the following beneficial effects:

[0019] The guide plate in the water tank anti-detachment state can resist the outer wall of the water tank, thereby returning the water tank to its proper position, effectively preventing the occurrence of the phenomenon of machine misjudgment and error reporting due to the failure of the water tank to be returned to its proper position in the prior art. At the same time, when the guide plate is in the water tank anti-detachment state, it can also prevent the uncontrollable risk of children pulling the water tank out of the placement cavity;

[0020] When the guide plate is in the anti-detachment state of the water tank, the guide plate can rotate along the first rotation direction to approach the outer side wall of the water tank and finally abut against the outer side wall of the box body, so that the box body can be limited in the opening; when the guide plate is in the drawn-out state of the water tank, the guide plate can rotate along the second rotation direction following the movement of the box body to avoid obstruction to the box body during the outward drawing and drawing process, and always abut against the outer side wall or bottom wall of the box body during the rotation process, so that auxiliary support can be formed for the box body to prevent the phenomenon that the internal condensed water splashes out due to the large change in the tilted position during the outward drawing and pulling of the water tank, until the water tank is separated from the chassis, the guide plate rotates to the horizontal state along the second rotation direction. At this time, the guide plate rotates to the horizontal state after the water tank is separated from the chassis, which can facilitate the smooth reset after the condensed water in the box body is dumped;

[0021] A handle that can be hinged to the top of the box is provided, and when the water tank is in the water collecting state, the handle has a portion that is exposed to the outside of the placement cavity and is in an open position. In this way, when the water tank assembled in the placement cavity needs to be pulled out to pour out the condensed water, it is only necessary to apply force to the aforementioned handle to pull out the box. For users who are too tall, they only need to bend over slightly, and for users of medium height, there is no need to bend over, let alone squat, to achieve the pulling and taking out of the box, and the operation is very convenient.

[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means intended to limit the present invention and its application or use. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] In the description of the present invention, it is necessary to understand that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings. They are only for the convenience of describing the present invention and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the devices or elements referred to must have a specific direction or be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the scope of protection of the present invention. The directional words "inside and outside" refer to the inside and outside relative to the contours of each component itself.

[0037] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings 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 "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0038] 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. If not otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of the present invention.

[0039] See also Figures 1 to 10As shown, according to an embodiment of the present invention, a dehumidifier is provided, including a dehumidifier body (not marked in the figure), a water tank 2, the dehumidifier body includes a rear side vertical plate 11 and a front panel (not shown in the figure) matched and buckled therewith, a main body space is formed between the front panel and the rear side vertical plate 11, and necessary components such as a condenser (not shown in the figure), a compressor (not shown in the figure), an evaporator (not shown in the figure), and a water receiving tray 4 are arranged in the main body space. The connection relationship of the aforementioned components is a conventional technology for dehumidifier design, and the present invention will not repeat it. The rear side vertical plate 11 has an opening 113 corresponding to the placement cavity of the dehumidifier body, and a bottom plate 3 is provided at the bottom of the placement cavity. The aforementioned placement cavity can be understood as a part of the aforementioned host space. The water tank 2 is assembled in the placement cavity via the opening 113. The water tank 2 includes a box body 21 and a handle 22 hinged to the top of the box body 21. The aforementioned hinge is specifically, for example, a rotating shaft is respectively arranged on both sides of the handle 22, and a rotatable connection is formed with the assembly hole on the top wall of the box body 21 through the rotating shaft. The water tank 2 has The water tank 2 is assembled in the placement cavity in a water collecting state and in a water pouring state outside the placement cavity. In the water collecting state, the handle 22 has a portion exposed to the outside of the placement cavity and located at the position of the opening 113, so that the operator can apply force to pull the handle 22 to switch the water tank 2 from the water collecting state to the water pouring state. The aforementioned water pouring state is that the user tilts the box body 21 so that the condensed water collected in the box body 21 is poured to a target location, such as a sewer, etc. The aforementioned water collecting state is that the water tank 2 is in the placement cavity so that The condensed water in the water receiving tray 4 generated by the operation of the condenser can be collected and guided into the box body 21. The box body 21 is assembled in the placement cavity through the opening 113 and is located on the bottom plate 3. In a preferred embodiment, corresponding rollers can be arranged between the bottom surface of the box body 21 and the top surface of the bottom plate 3 to ensure that when the user applies force to the handle 22 to pull the box body 21 outward, the box body 21 can achieve displacement change more smoothly. A guide plate 31 is arranged on the outer edge of the bottom plate 3 corresponding to the opening 113, specifically Figure 6 The orientation shown in the figure is used as a reference. The guide plate 31 is arranged at the right edge of the chassis 3. The guide plate 31 has a water tank anti-detachment state, which corresponds to the aforementioned water collecting state. When the guide plate 31 is in the water tank anti-detachment state, the guide plate 31 can rotate along the first rotation direction (with Figure 6 The orientation shown is for reference, and the first rotation direction (i.e., counterclockwise) rotates close to the outer wall of the water tank 2 and finally abuts against the outer wall of the box body 21, thereby limiting the box body 21 in the opening 113.

[0040] In this technical solution, a guide plate 31 that can be driven to rotate is provided on the outer edge of the chassis 3, so that when the condensed water in the water tank 2 is poured out and reassembled in the placement cavity, the guide plate 31 in the water tank anti-detachment state can exert a resistance force on the outer wall of the water tank 2, thereby returning the water tank 2 to its proper position, effectively preventing the phenomenon in the prior art that the machine misjudges and reports errors due to the water tank 2 not being properly reset. At the same time, when the guide plate 31 is in the water tank anti-detachment state, it can also prevent the uncontrollable risk of children pulling the water tank 2 out of the placement cavity.

[0041] In another preferred embodiment, the guide plate 31 also has a water tank pull-out state, which corresponds to the aforementioned pouring state. When the guide plate 31 is in the water tank anti-detachment state, the guide plate 31 can rotate along the first rotation direction (with Figure 6 The guide plate 31 is rotated in the first direction (i.e., counterclockwise) to approach the outer wall of the water tank 2 and finally abut against the outer wall of the box body 21, so that the box body 21 can be limited in the opening 113. When the guide plate 31 is in the water tank pulling state, the guide plate 31 can be rotated in the second direction (i.e., counterclockwise) to approach the outer wall of the water tank 2 and finally abut against the outer wall of the box body 21. Figure 6 The shown orientation is for reference, and the second rotation direction is clockwise) follows the movement and rotation of the box body 21 to avoid obstruction to the box body 21 during the outward pulling process, and always contacts the outer wall or bottom wall of the box body during the rotation process, so that auxiliary support can be formed for the box body 21 to prevent the internal condensed water from splashing out due to the large change in the tilt position during the water tank being pulled outward, until the water tank 2 is separated from the chassis 3, the guide plate 31 rotates along the second rotation direction to a horizontal state. At this time, the guide plate 31 rotates to a horizontal state after the water tank 2 is separated from the chassis 3, which can facilitate the subsequent smooth reset after the condensed water in the box body 21 is dumped (that is, the process of assembling it in the placement cavity).

[0042] It should be noted that a handle 22 that can be hinged thereto is provided on the top of the box body 21, and when the water tank 2 is in the water collecting state, the handle 22 has a portion exposed to the outside of the placement cavity and located at the opening 113. In this way, when it is necessary to pull out the water tank 2 assembled in the placement cavity to pour out the condensed water, it is only necessary to apply force to the handle 22 to pull out the box body 21. Users who are too tall only need to bend over slightly, and users of medium height do not need to bend over, let alone squat, to achieve the pulling and taking out of the box body 21, which is very convenient to operate.

[0043] See also Figure 2 and Figure 5As shown, the guide plate 31 also has a rotation driving component 32, and the rotation driving component 32 is used to drive the guide plate 31 to rotate forward or reversely to realize the switching of the guide plate 31 between the water tank anti-detachment state and the water tank pulling state. Specifically, the aforementioned rotation driving component 32 includes a rotary motor 321, and a driving gear 322 is mounted on the output shaft of the rotary motor 321. The two ends of the guide plate 31 are rotatably connected to the two sides of the chassis 3 through a rotating shaft, wherein a driven gear 323 is mounted on the rotating shaft at one end, and the driven gear 323 is meshed with the driving gear 322. When the rotary motor 321 is running, the driving gear 322 is driven to rotate forward or reverse, and then the guide plate 31 is driven to flip along the first rotation direction or the second rotation direction through the driven gear 323 to realize state switching, with a simple structure and efficient transmission.

[0044] In some embodiments, the box body 21 has an outer wall (that is, the side facing the external space rather than the aforementioned placement cavity space). When the water tank 2 is in the water collecting state, the handle 22 is horizontally supported by the top surface of the outer wall, and the outer side surface of the handle 22 does not protrude from the wall surface of the outer wall. The outer wall has a hand-picking groove 211 that is recessed toward the inner side of the placement cavity. A finger passage gap (not marked in the figure) is formed between the inner side surface of the handle 22 (that is, the side facing the inside of the placement cavity) and the inner groove wall of the hand-picking groove 211. In a preferred embodiment, the outer side surface of the handle 22, the wall surface of the outer side wall of the box body 21, and the rear wall surface of the rear side vertical plate 11 are on the same vertical plane.

[0045] In this technical solution, by designing the outer side surface of the handle 22 to be concave or flush with the rear wall surface of the rear vertical plate 11, the appearance consistency of the dehumidifier can be improved, and damage that may be caused by the protruding structure of the handle 22 can be prevented.

[0046] In some embodiments, the upper edge of the opening 113 has a horizontal plate 111 extending horizontally toward the inner side of the placement cavity, and the horizontal plate 111 is located on the rear side vertical plate 11. In a specific embodiment, the horizontal plate 111 and the rear side vertical plate 11 are integrally injection molded, and a plurality of position detection sensors 112 are arranged on the bottom surface of the horizontal plate 111. When the water tank 2 is in the water collecting state, the dimension of the handle 22 in the direction of pulling the water tank 2 horizontally outward is defined as its width, and the plurality of position detection sensors 112 are arranged at intervals along the width, and the vertical downward projections of each position detection sensor 112 are all within the width range. In this way, by arranging the plurality of position detection sensors 112 arranged at intervals along the width of the handle 22, the state position of the handle 22 can be detected in real time, which is conducive to the subsequent precise control of the pulling and resetting of the water tank 2.

[0047] See Figure 7 As shown, in some embodiments, the handle 22 is close to one side of the placement cavity (i.e. Figure 7 A finger holding groove 221 is formed on the top surface of the handle 22 (the left side surface of the handle 22 in the figure), and the finger holding groove 221 is connected with the hand picking groove 211 to ensure that the operator's fingers can extend into the finger holding groove 221 through the hand picking groove 211 and the finger passing gap.

[0048] In this technical solution, by reserving a corresponding finger grip groove 221 on the inner top surface of the handle 22, the user can securely grip the inner part of the handle 22 with his fingers when applying force on the handle 22 to pull out the box body 21, thereby ensuring the reliability and stability of the force applied during the process of pulling out the box body 21 and preventing the box body 21 from falling during the process of pulling out the box body 21.

[0049] Continue to see Figure 1 As shown, a splash cover 23 is provided in the top opening of the water tank 2, and the handle 22 is assembled in the upper area of ​​the splash cover 23 to prevent the condensed water from splashing due to excessive shaking of the condensed water in the water tank 2 during the pulling process. Specifically, the splash cover 23 includes a fixed cover plate 231 fixed relative to the position of the box body 21 and a movable rotating cover plate 232 hinged to one side of the fixed cover plate 231. When the condensed water needs to be poured out, it is only necessary to tilt the box body 21, and the movable rotating cover plate 232 will open an outlet under the action of its own weight for the condensed water to flow out. It can be understood that a water drop structure corresponding to the outlet of the water receiving tray 4 is also formed on the fixed cover plate 231 and / or the movable rotating cover plate 232, so that the condensed water received in the water receiving tray 4 can be guided into the box body 21.

[0050] According to an embodiment of the present invention, there is also provided a control method for the dehumidifier as described above, comprising the following steps:

[0051] Obtaining the real-time position information of the water tank 2 and obtaining the control instructions of the dehumidifier;

[0052] According to the real-time position of the water tank 2 and the control instruction, the rotation of the guide plate 31 is controlled so that the guide plate 31 can be switched between the water tank anti-slip state and the water tank pulling state.

[0053] See also Figure 7 As shown, there are three position detection sensors 112, each of which is arranged at intervals along the width direction of the handle 22, that is, along the horizontal direction of the water tank 2. According to the real-time position of the water tank 2 and the control instruction, the rotation of the guide plate 31 is controlled so that the guide plate 31 can be switched between the water tank anti-slip state and the water tank pulling state. Specifically, it includes:

[0054] When the control instruction is a water tank reset instruction, the handle 22 is detected by two position detection sensors located on the inner side and the outer side of each position detection sensor 12 (the inner side and the outer side here refer to the relative position relationship between the position detection sensor and the inner side of the aforementioned placement cavity, or the relative position relationship with the external environment, for example, the inner side is far away from the external environment and the outer side is close to the external environment). When both the inner and outer position detection sensors detect the handle 22, the guide plate 31 is controlled to be at a position forming a first angle a1 with the horizontal plane so that the guide plate 31 is in the water tank anti-detachment state, that is, when the inner and outer position detection sensors detect the handle 22, the guide plate 31 is controlled to be at a position forming a first angle a1 with the horizontal plane so that the guide plate 31 is in the water tank anti-detachment state. When the inner position detection sensor does not detect the handle 22 and the outer position detection sensor detects the handle 22, it indicates that the water tank 2 is in the process of moving from the outside of the opening 113 to the inside (that is, in the placement cavity) (part of the water tank 2 is in the opening 113), and at this time, the guide plate 31 is controlled to be at the second angle a1 with the horizontal plane. The position of a2 can form a certain degree of auxiliary inward push for the outer wall or bottom wall of the inclined box body 21, making the user's water tank reset operation more convenient; when the inner and outer position detection sensors do not detect the handle 22, it means that the water tank 2 is completely outside the opening 113. At this time, in order to ensure that the box body 21 can enter the opening 113 more smoothly, the guide plate 31 is controlled to be at a position at a third angle a3 to the horizontal plane, wherein a1>a2>a3, and the aforementioned a1, a2 and a3 are specifically determined according to the spacing between the position detection sensors 112 and the relative distance to the opening 113. Generally speaking, in order to prevent The inclined guide plate 31 hinders the reset process of the box body 21. The aforementioned third angle a3 is designed to be 0°, that is, the guide plate 31 is in a horizontal position. In this technical solution, by controlling the guide plate 31 to deflect a certain angle (that is, the aforementioned second angle a2) during the reset process of the water tank to follow the box body 21 into the placement cavity, on the one hand, the inclined box body 21 can be pushed inwardly during the reset process, which makes it more convenient for the user to reset. On the other hand, after the box body 21 is reset in place, the guide plate 31 can be controlled at the third angle a3 to achieve the purpose of limiting the box body 21, and the water tank can be reset in place to prevent the dehumidifier from misjudging the machine damage. At this time, in a specific embodiment, a3 is 90°, that is, perpendicular to the horizontal plane, and a2 is 45°.

[0055] See Fig.10As shown, a logical flow of water tank reset control in an embodiment is shown. F1 and F3 in the figure correspond to the detection signals of the inner position detection sensor and the outer position detection sensor mentioned above, respectively. When F1=0 or F3=0, it means that the corresponding position detection sensor has not detected the handle 22 below it, which means that the water tank 2 is not in the corresponding position at this time. On the contrary, when F1=1 or F3=1, it means that the water tank 2 is in the corresponding position. Of course, for the middle position detection sensor between the inner position detection sensor and the outer position detection sensor, when F2=0, it means that the water tank 2 is already thereunder, and when F2=1, it means that the water tank 2 is not thereunder. It will not be elaborated here. In the figure, the guide plate maintains the maximum angle without moving, which means that the aforementioned third angle a3 is formed between the guide plate and the horizontal plane.

[0056] When the control instruction is a water tank pulling instruction, the handle 22 is detected by each of the position detection sensors 12. When each of the position detection sensors 12 detects the handle 22, it means that the water tank 2 is in the initial state. The guide plate 31 needs to be deflected toward the outside of the opening 113 by a certain angle to avoid obstruction to the outward pulling of the water tank 2. Therefore, the guide plate 31 is controlled to be at a position forming a fourth angle a4 with the horizontal plane. Figure 8In the direction shown, the aforementioned rotary motor 231 is controlled to rotate so that the guide plate 31 rotates clockwise; when the inner position detection sensor does not detect the handle 22, and the remaining position detection sensors 12 (i.e., the middle position detection sensor and the outer position detection sensor) all detect the handle 22, it means that the box body 21 is partially inside the opening 113, so the guide plate 31 is controlled to be at a position forming a fifth angle a5 with the horizontal plane, and the guide plate 31 deflected at a certain angle forms an auxiliary support for the outer wall or bottom wall of the box body 21, so that the box body 21 is in a relatively stable tilted state; when the outer position detection sensor When the position detection sensor detects the handle 22 and the remaining position detection sensors 12 do not detect the handle 22, it means that the box 21 is closer to the opening 113, and the guide plate 31 is controlled to be at a position that forms a sixth angle a6 with the horizontal plane, which further facilitates the smooth pulling out of the box 21 from the opening 113; when the position detection sensors 12 do not detect the handle 22, it means that the box 21 is completely pulled out of the opening and is outside, and the guide plate 31 is controlled to be at a position that forms a seventh angle a7 with the horizontal plane, a4>a5>a6>a7, so that the subsequent reset of the water tank 2 can be smoothly carried out. In this technical solution, by controlling the guide plate 31 to deflect a certain angle (that is, the fourth angle a4 to the seventh angle a7) during the process of pulling out the water tank, auxiliary support for the inclined box 21 can be achieved during the pulling process, effectively preventing the box 21 from shaking and splashing due to the unstable position switching during the pulling process.

[0057] In a specific embodiment, the aforementioned a7 and a3 can select the same angle value, for example, both are 0°, that is, the guide plates 31 at the two positions are in a horizontal state, and the selection of the specific angle values ​​of the aforementioned a4, a5 and a6 is specifically determined based on the spacing between each position detection sensor 112 and the relative distance from the opening 113. In a specific embodiment, a4=70°, a5=45°, a6=30°, and a7=0°.

[0058] In some embodiments, when the control instruction is a water tank pull-out instruction, a child lock instruction configured for the dehumidifier is also obtained. When the child lock instruction is obtained, the guide plate 31 is controlled to be at a position that forms a first angle a1 with the horizontal plane so that the water tank 2 is in the water tank anti-detachment state to prevent children from accidentally touching or operating the water tank 2. When the child lock instruction is not obtained, the water tank pull-out instruction is executed normally. At this time, the guide plate 31 is controlled to be at a position that forms a fourth angle a4 with the horizontal plane, so that the box body 21 is pulled out of the opening part while the guide plate 31 at this angle position forms auxiliary support for the outer wall surface of the box body 21. The aforementioned child lock instruction can be specifically selected by setting a corresponding child lock button on the dehumidifier host. For example, when the child lock button is pressed, the corresponding control component will obtain the child lock instruction. On the contrary, if the child lock button is not pressed, the control component will not obtain the child lock instruction.
