When the water tank 200 is pulled in the direction of leaving the body 100, the first guide member 320 and the second guide member 420 cooperate to guide the first fastening member 310 and the second fastening member 410 to unlock, so that the water tank 200 can be separated from the body 100 at the same time during the outward movement. When the water tank 200 is placed into the accommodating groove 120 again, the first guide member 320 and the second guide member 420 guide the first fastening member 310 and the second fastening member 410 to lock, so that the water tank 200 can be fixed in the accommodating groove 120 at the same time during the inward movement. In this way, the mobile water tank 200 is integrated with the locking and unlocking functions, making the operation smoother, effectively improving the operating efficiency, and allowing the user to easily take out the water tank 200, thereby enhancing the user experience.

[0041] like Figure 3 and Figure 4As shown, in this specific embodiment, two first fastening members 310 are provided, and the two first fastening members 310 are symmetrically arranged on the body 100 along the left-right direction. Correspondingly, two second fastening members 410 are provided, and the first fastening member 310 is arranged on the upper groove wall of the accommodating groove 120 and is arranged downward in the accommodating groove 120, and the second fastening member 410 is arranged at the upper end of the water tank cover 220. When the water tank 200 is located in the accommodating groove 120, the first fastening member 310 and the second fastening member 410 are correspondingly fastened to fix the water tank 200 in the accommodating groove 120.

[0042] Specifically, the first fastening member 310 and the first guide member 320 are integrally formed.

[0043] Specifically, the first fastening member 310 and the second fastening member 410 are claws that can be fastened to each other.

[0044] In some specific embodiments of the present invention, a movable member 210 is further included, the movable member 210 is movably connected to the water tank 200, and the second guide member 420 is disposed on the movable member 210. Figure 5 As shown, in this specific embodiment, the movable part 210 is a water tank handle 211, and the water tank handle 211 is rotatably connected to the water tank 200.

[0045] In some specific embodiments of the present invention, the second guide member 420 includes a first guide portion 421 and a second guide portion 422. The first guide portion 421 and the second guide portion 422 are arranged on the water tank in sequence along the connection direction between the water tank and the body. The first guide portion 421 cooperates with the first guide member 320 to guide the first fastening member 310 and the second fastening member 410 to separate, and the second guide portion 422 cooperates with the first guide member 320 to guide the first fastening member 310 and the second fastening member 410 to fasten.

[0046] like Figure 4 As shown, the first guide member 320 is provided at the right end of the first fastening member 310. Figure 5As shown, both the first guide portion 421 and the second guide portion 422 are provided on the water tank handle 211. It should be noted that the water tank handle 2111 includes a gripping handle 2111 and two connecting handles 2112. The gripping handle 2111 is provided in the left-right direction, and the connecting handles 2112 are provided in the front-back direction. The two connecting handles 2112 are respectively provided at the left and right ends of the gripping handle 2111. Specifically, two first guide members 320 are provided, and two second guide members 420 are provided. The two second guide members 420 are respectively provided on the connecting handles 2112 at the left and right ends of the water tank handle 211. A second guide portion 422 is provided at the rear end of each first guide portion 421. Therefore, when the water tank 200 is pulled forward, the first guide portion 421 guides the first guide member 320 to disengage from the second guide member 420, so that the first snapping portion 511 is separated from the second snapping portion 511, thereby unlocking the water tank 200 and the body 100, so that the water tank 200 can smoothly separate the body 100 from the water tank 200 during the process of pulling the water tank 200 forward. When the water tank 200 is placed into the accommodating groove 120 again, the second guide portion 422 guides the first snapping member 310 to move toward the second snapping member 410 until the first snapping member 310 and the second snapping member 410 are snapped with each other, thereby locking the water tank 200 and the body 100, so that the water tank 200 can be fixed in the accommodating groove 120 at the same time during the process of moving backward, thereby making the operation smoother and improving the operating efficiency.

[0047] Specifically, the first guide portion 421 , the second guide portion 422 and the water tank handle 211 are integrally formed.

[0048] In some specific embodiments of the present invention, the cross-sectional area of ​​the first guide member 320 gradually decreases along the middle toward the opposite ends close to and away from the body 100, the cross-sectional area of ​​the first guide portion 421 gradually increases in the direction close to the body 100, and the cross-sectional area of ​​the second guide portion 422 gradually decreases in the direction close to the body 100.

[0049] like Figure 4 、 Figure 5 and Figure 9As shown, the first guide member 320 is an arc-shaped protrusion, and its cross-sectional area gradually decreases from the middle toward the front and rear ends. Correspondingly, the first guide portion 421 is a groove, and the rear end of the groove has a separation guide inclined surface 4211. When the water tank 200 is pulled forward, the separation guide inclined surface 4211 cooperates with the arc-shaped protrusion. Under the guidance of the separation guide inclined surface 4211 and the arc-shaped protrusion, the first buckling portion 511 bends upward and separates from the second buckling portion 511, thereby unlocking the water tank 200 and the body 100. The second guide portion 422 has a first installation guide bevel 4221 and a second installation guide bevel 4222. The first installation guide bevel 4221 is located at the rear end of the second installation guide bevel 4222. The slope of the first installation guide bevel 4221 is greater than the slope of the second installation guide bevel 4222. When the water tank 200 is placed into the accommodating groove 120, the first fastening component 310 first abuts against the first installation guide bevel 4221. Under the guidance of the first installation guide bevel 4221, the first fastening component 310 abuts against the second installation guide bevel 4222. Under the action of the second installation guide bevel 4222, the first fastening component 310 and the second fastening component 410 are smoothly fastened, thereby locking the water tank 200 and the body 100.

[0050] In some specific embodiments of the present invention, the first fastening assembly 300 further includes an elastic member 330, which is disposed on the first fastening member 310. The first fastening member 310 is movably connected to the body 100 via the elastic member 330. Specifically, the number of the elastic members 330 is the same as the number of the first fastening members 310. Each first fastening member 310 is correspondingly provided with an elastic member 330. The first fastening member 310 is movably connected to the body 100 via the elastic member 330. Figure 4 As shown, the elastic member 330 is located in the accommodating groove 120, which is arranged in the up and down directions, and the first fastening member 310 is arranged in the horizontal direction. The upper end of the elastic member 330 is connected to the body 100, and the lower end is connected to the first fastening member 310. Thus, the separation guide inclined surface 4211 cooperates with the arc-shaped protrusion. Under the elastic action of the elastic member 330, the first fastening portion 511 bends upward and separates from the second fastening portion 511, thereby realizing the unlocking of the water tank 200 and the body 100.

[0051] In some specific embodiments of the present invention, a limiting assembly 500 is further included. The limiting assembly 500 is connected to the water tank cover 220 , and the limiting assembly 500 is connected to the water tank handle 211 . The limiting assembly 500 is used to limit the moving direction of the water tank handle 211 .

[0052] In some specific embodiments of the present invention, the limiting assembly 500 includes: a limiting column 510, which is arranged on the water tank handle 211; a limiting groove 520, which is opened on the water tank cover 220, and the limiting groove 520 extends along the separation direction of the water tank 200 and the body 100, and the limiting column 510 slides through the limiting groove 520.

[0053] like Figure 5 and Figure 6 As shown, there are two limit grooves 520, and the two limit grooves 520 are both arranged on the water tank cover 220 along the left and right directions. The limit grooves 520 extend along the front and back directions. Correspondingly, there are two limit columns 510, and the two limit columns 510 are respectively located at the left and right ends of the water tank handle 211 and are movably passed through the corresponding limit grooves 520. The limit column 510 has a buckling portion 511 at the end away from the water tank handle 211 to prevent the water tank handle 211 from slipping out of the limit groove 520 when moving along the channel restricted by the limit groove 520. Therefore, when the water tank 200 is placed backward into the accommodating groove 120, the second guide portion 422 guides the first fastening member 310 to move toward the second fastening member 410 until the first fastening member 310 and the second fastening member 410 are fastened to each other. At this time, the water tank handle 211 is still outside the body 100. Pressing the water tank handle 211 backward causes the limiting column 510 to move along the channel restricted by the limiting groove 520 until the first guide member 320 is fastened with the first guide portion 421. Specifically, the first guide member 320 cooperates with the first installation guide inclined surface 4221, the second installation guide inclined surface 4222, and the separation guide inclined surface 4211 in sequence, driving the first fastening member 310 to lift up first and then resume downward pressure. At this time, the first fastening member 310 is fastened with the second fastening member 410 again, and the installation is completed.

[0054] In some specific embodiments of the present invention, a sliding assembly 600 is further included. The sliding assembly 600 is connected to the water tank 200 , and the sliding assembly 600 is connected to the body 100 . The sliding assembly 600 is used to improve the portability of the water tank 200 .

[0055] In some specific embodiments of the present invention, the sliding assembly 600 includes: a pulley 610, which is arranged at the bottom end of the water tank 200; a slide groove 620, which is arranged on the chassis 110, and the slide groove 620 corresponds to the pulley 610, and the slide groove 620 extends along the separation direction of the water tank 200 and the body 100.

[0056] In some specific embodiments of the present invention, both ends of the pulley 610 have a correction piece 611 , and the cross-sectional area of ​​the correction piece 611 gradually decreases in a direction away from the pulley 610 .

[0057] like Figure 7 and Figure 8As shown, four pulleys 610 are provided and two slide grooves 620 are provided, each slide groove 620 corresponds to two pulleys 610, the correction member 611 is conical in shape, and the cross-section of the corresponding slide groove 620 is trapezoidal in shape. The pulley 610 and the slide groove 620 cooperate with each other to ensure that the pulley 610 is automatically corrected and does not derail during the rolling process. Therefore, when it is necessary to clean the waste water in the water tank 200, the first fastening member 310 and the second fastening member 410 are separated when the handle is pulled, and the locking state between the water tank 200 and the body 100 is released, and then the water tank 200 is smoothly pulled out under the push of the pulley 610, thereby reducing the burden of manual handling and improving the user experience.

[0058] In some specific embodiments of the present invention, when the dehumidifier is operating, condensed water in the body 100 slowly drips into the water collection port of the water tank cover 220, where it collects and then drips into the water tank 200. When the water tank is full, the dehumidifier automatically shuts off and enters standby mode. At this time, the water tank handle 211 is pulled forward. As the water tank handle 211 slides along the limit groove 520, the separation guide inclined surface 4211 on the water tank handle 211 immediately pushes the arc-shaped protrusion upward, thereby driving the first fastening member 310 upward as a whole, and the first fastening member 310 and the second fastening member 410 are disengaged. The water tank handle 211 is pulled forward until it slides to the end of the limit groove 520. At this time, the force acting on the water tank handle 211 is transferred to the water tank 200, and the four pulleys 610 roll along the two slide grooves 620, pushing the water tank 200 outward until it is completely separated from the accommodating tank 120. After the water tank 200 is separated from the dehumidifier body, the user can flip the water tank handle 211 to a vertical state along the limit groove 520, bend the fingers and hold the water tank handle 211 tightly to lift the water tank 200, or hold the water tank handle 211 and use the pulley 610 to pull the water tank 200 to the drain.

[0059] After the wastewater is dumped, the pulley 610 is aligned with the chute 620 and the water tank 200 is pushed backward until a "click" sound is heard. At this time, the second fastening member 410 on the water tank cover 220 is fastened to the first fastening member 310. It should be noted that at this time, the water tank handle 211 is still outside the water tank 200. The water tank handle 211 is pressed along the limit groove 520 until a "click" sound is heard again. The arc-shaped protrusion cooperates with the first installation guide slope 4221, the second installation guide slope 4222, and the separation guide slope 4211 in sequence, driving the first fastening member 310 to first lift up and then resume downward pressure. At this time, the first fastening member 310 is again fastened to the second fastening member 410, thus completing the installation of the water tank 200 and the body 100.

[0060] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in the technical field without departing from the purpose of the present invention.
