An electric cylinder is fixed to the top end surface and the bottom end surface of the inner wall of the equipment box, and the protruding ends of the two electric cylinders are fixed on the seat body. Adjustment blocks are welded on the seat body in a rectangular array. The rectangular array-welded adjustment blocks are aligned with the rectangular array-shaped through holes. When the seat body moves to the left, the adjustment blocks and the through holes are in a plug-in state.

[0009] Furthermore, the adjustment blocks welded in a rectangular array are cylindrical block structures, and the left end of each adjustment block is polished. After polishing, the left end of each adjustment block is a pointed structure, and the diameter of the adjustment block is equal to the inner diameter of the through hole.

[0010] Furthermore, a second filter plate is installed in the device case, and the second filter plate is located between the adjustment component and the baffle; a cleaning component is installed in the device case, and the cleaning component consists of a base block, a connecting rod, a blocking block, a cleaning block, a first motor and a first threaded rod. The base block slides inside the device case, and a cleaning block is fixed on the right end face of the base block. The right end face of the cleaning block contacts the left end face of the second filter plate. A first motor is fixed on the top surface of the device case, and a first threaded rod is fixed on the output shaft of the first motor.

The front end and rear end faces of the scraper block are welded with a mounting arm, and both mounting arms are L-shaped block structures. A spring rod is fixed on each mounting arm, and the protruding ends of the two spring rods are in contact with the front end and rear end faces of the equipment box respectively. When the scraper block moves downward, the two spring rods are in a continuous elastic clamping state with the protrusions. The protruding ends of the two spring rods are polished. After polishing, the protruding ends of the two spring rods are both arc-shaped structures.

[0016] Compared with the prior art, the present invention has the following beneficial effects: In terms of energy saving, the heat exchange core in the heat exchange assembly of this application can efficiently recover the waste heat in the indoor return air and use it to preheat the fresh air. This process realizes the recycling of heat and greatly reduces the energy consumption of the system. At the same time, the second motor drives the adjustment rod to rotate, and the distance between the two baffles can be flexibly adjusted, thereby changing the width of the U-shaped channel. When it is necessary to speed up the gas flow rate, the channel width can be increased to allow the gas to pass quickly to complete the initial heat exchange. To improve the heat exchange effect, the channel width can be reduced, the gas flow rate can be slowed down, and the gas and the heat exchange core can have more sufficient contact time. In addition, the first auxiliary block and the second auxiliary block are staggered, like building a complex maze path, which significantly extends the gas flow path in the heat exchange area, further improving the heat exchange efficiency, and achieving the dual goals of energy saving and efficient heat exchange.

[0017] In terms of performance optimization, the application utilizes an electric cylinder-driven housing and an adjustment block, enabling precise adjustment of the through-hole size on the first filter plate. In different usage scenarios, such as when ambient dust concentration changes, the through-hole size can be increased or decreased based on actual needs, ensuring effective air circulation while also controlling the filtration effect. When a through-hole becomes clogged, affecting air circulation, the adjustment block can also serve as a clearing tool, quickly unclogging the hole. When not in use, the adjustment block is inserted into the through-hole to seal it, forming a solid protective barrier that effectively prevents dust and other impurities from entering the device, protecting the precision components within and extending the dehumidifier's service life.

[0018] In this application, through the setting of the cleaning component, the first motor drives the first threaded rod to rotate, and the base block drives the cleaning block to move, thereby carefully wiping and cleaning the second filter plate; during the cleaning process, the blocking block moves synchronously, cleverly opening up a discharge channel for debris, ensuring a smooth and unobstructed cleaning process, so that the second filter plate always maintains good filtering performance and maintains the stability of the air purification effect.

[0019] This application uses a backward-inclined fan setting. Compared with the traditional centrifugal fan, the backward-inclined fan does not require additional complex air ducts to form wind pressure, and can efficiently discharge the air in the evaporator and condenser; this design greatly saves the internal space of the equipment and makes the overall structure more compact.

[0020] In terms of functional diversity, the silica gel calcium oxide filled in the first filter box and the activated carbon in the second filter box work synergistically, which can not only effectively remove harmful gases such as formaldehyde in the air, but also have the function of filtering PM2.5. At the same time, it can deeply dehumidify the humid air, creating a healthy and comfortable indoor air environment for users.

[0021] In this application, through the setting of the scraping assembly, the third motor drives the second threaded rod to rotate, and the scraping block moves downward along the second sliding seat to thoroughly clean the debris on the left side of the first filter plate; the continuous elastic card connection design between the spring rod and the protrusion is very ingenious, and continuous vibration is generated during the movement of the scraping block, which helps to shake off the stubborn debris attached to the surface of the filter plate.

When the base body 202 moves to the left, the adjustment block 203 and the through-hole 102 are in a plug-in state. During use, when the size of the through-hole 102 needs to be adjusted, the two electric cylinders 201 are driven to extend. The two electric cylinders 201 drive the base body 202 and the adjustment block 203 to move to the left.

Under the threaded drive of the first threaded rod 306, the base block 301 drives the cleaning block 304 to move downward to complete the wiping and cleaning of the second filter plate 103. When the base block 301 moves downward, the blocking block 303 moves downward. At this time, the debris is discharged through the plug hole of the base block 301.

[0041] Among them, a backward-inclined fan 7 is installed in the equipment box 1, and the backward-inclined fan 7 is located on the right side of the condenser 6.

The size of the through hole 102 can be adjusted by plugging the adjusting block 203 into the through hole 102, and the through hole 102 can also be unblocked by the adjusting block 203; when the second filter plate 103 needs to be cleaned, the first motor 305 is driven to rotate, and the first motor 305 drives the first threaded rod 306 to rotate. Under the thread drive of the first threaded rod 306, the base block 301 drives the cleaning block 304 to move downward to complete the wiping and cleaning of the second filter plate 103. When the base block 301 moves downward, the blocking block 303 moves downward, and at this time, debris is discharged through the plug hole of the base block 301; when the debris on the left side of the first filter plate 101 is cleared, the third motor 904 is driven to rotate, The third motor 904 drives the second threaded rod 903 to rotate, and the scraper block 902 moves downward under the thread drive of the second threaded rod 903 to complete the cleaning of the debris on the left side of the first filter plate 101; at the same time, the continuous elastic engagement between the spring rod 907 and the protrusion 905 can generate vibration, which can assist in shaking off the debris on the left end face of the first filter plate 101, and because the protruding ends of the two spring rods 907 are both arc-shaped structures, the wear of the spring rod 907 and the protrusion 905 can be reduced when in use; when not in use, the two electric cylinders 201 are driven to extend until the cylindrical part of the adjustment block 203 is inserted into the through hole 102, at which time the through hole 102 can be sealed.
