[0028] In order to more clearly understand the above-mentioned objectives, features and advantages of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the embodiments of the present application and the features therein can be combined with each other without conflict.

[0029] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0030] Some embodiments of the present invention are described below with reference to the accompanying drawings. Example 1

[0031] like Figures 1 to 10As shown, this embodiment discloses a dehumidifier with a variable air duct, comprising: a shell 1, wherein a condensing plate 2, a heat sink 3 and a fan 4 are sequentially arranged inside the shell 1, a cooling plate 5 is arranged between the condensing plate 2 and the heat sink 3, at least one air inlet 6 is opened on the side end face of the shell 1, and an air regulating component 7 is arranged on the inner wall of the shell 1 on the side of at least one of the air inlet 6.

[0032] This embodiment is capable of adjusting the air intake volume, air intake speed and air intake direction by setting an air regulating component 7, so that the air intake ratio can be adjusted under different humidity environments, and the temperature difference between the condensing plate 2 and the external air can be controlled and changed by different air inlets 6 and their sizes, so that the temperature difference value is always maintained at the optimal temperature difference corresponding to different humidity conditions, thereby making the dehumidification efficiency of the dehumidifier always maintained at the highest value, and realizing the function of maintaining the high-efficiency operation of the dehumidifier when switching between two usage scenarios with large humidity differences; and by setting multiple groups of air inlets 6, the heat dissipation efficiency of the heat sink 3 and the fan 4 is improved, thereby improving the overall operation efficiency of the dehumidifier.

[0033] At least one air outlet 8 is provided on the top surface or side surface of the shell 1, and one end of the air outlet duct 9 is connected to the inside of the air outlet 8, and the other end of the air outlet duct 9 is connected to the heat sink 3; the condensing sheet 2 is condensing aluminum, and the heat sink 3 is heat dissipating aluminum. The aluminum material has good thermal conductivity and can quickly and effectively conduct heat, thereby improving the cooling efficiency and heat dissipation effect of the dehumidifier; when the refrigeration sheet 5 is working, its cold surface close to the condensing sheet 2 absorbs heat, reducing the temperature of the condensing sheet 2, while the hot surface close to the heat sink 3 releases heat. After the heat is dispersed through the heat sink 3, the heat of the heat sink 3 is discharged to the air outlet duct 9 through the fan 4, and then discharged out of the dehumidifier; the dehumidified air flows along the channel below the condensing sheet 2 toward the fan 4, and the fan 4 blows it toward the heat sink 3, goes up along the heat sink 3, and finally is discharged back to the use environment through the air outlet duct 9 from the air outlet 8 on the top or side of the shell 1, thereby reducing the relative humidity of the use environment.

[0034] A movable groove 10 is further provided on the end surface of the housing 1 on one side of the air inlet 6. A paddle 11 is movably disposed within the movable groove 10. One end of the paddle 11 protrudes from the exterior of the housing 1, while the other end passes through the movable groove 10 and is fixedly connected to the air adjustment assembly 7. A limit assembly 12 is provided on the inner sidewall of the movable groove 10. The limit assembly 12 limits the up and down movement of the paddle 11 within the movable groove 10, thereby driving the air adjustment assembly 7 to move up and down, thereby shielding the air inlet 6 at different positions and achieving the purpose of air adjustment.

[0035] The air adjustment assembly 7 includes a limit frame 13, with slide posts 14 symmetrically arranged on both sides of the limit frame 13. An upper limit plate 15 and a lower limit plate 16 are arranged in the middle of the slide post 14. A baffle 17 is arranged between the upper limit plate 15 and the lower limit plate 16. The baffle 17 is sleeved on both sides of the slide post 14 and is slidably connected to the slide post 14. The height of the baffle 17 is less than the distance between the upper limit plate 15 and the lower limit plate 16. The baffle 17 is fixedly connected to the paddle 11. The installation of the baffle 17 is restricted by the limit frame 13, the movement path of the baffle 17 is restricted by the slide post 14, and the movement range of the baffle 17 is restricted by the upper limit plate 15 and the lower limit plate 16. When the user pushes the paddle 11, the paddle 11 drives the baffle 17 to move in the slide post 14 between the upper baffle 17 and the lower baffle 17, forming different air inlet adjustment gears and achieving different air adjustment goals.

[0036] like Figure 10 As shown, the limit assembly 12 includes a limit groove 18, which is arranged in the inner wall of the shell 1 on both sides of the upper part of the movable groove 10, and the opposite side surfaces of the two groups of limit grooves 18 are communicated with the movable groove 10. A spring 19 is arranged inside the limit groove 18, and the opposite ends of the two groups of springs 19 are fixedly connected to the inner wall surface of the limit groove 18. The opposite ends of the two groups of springs 19 are fixedly connected to the limit block 20, and the distance between the two groups of limit blocks 20 is less than the width of the paddle 11. The limit block 20 is provided with a first inclined surface 21 and a second inclined surface 22, and the paddle 11 is arranged above or below the limit block 20. When the adjustment paddle 11 moves from the bottom of the movable groove 10 to the top of the movable groove 10, the paddle 11 is pressed upward by the second inclined surface 22, and the limit block 20 is subjected to pressure in the direction of the spring 19. The spring 19 is compressed to both sides, so that the paddle 11 passes through the limit block 20 and reaches the top of the movable groove 10. After releasing the paddle 11, the spring 19 recovers, causing the limit block 20 to return to its original position, so that the limit block 20 can be used to support the paddle 11 and prevent it from falling down; when the paddle 11 is pushed to move downward, the thrust is greater than the elastic force, so that the paddle 11 is pressed downward by the first inclined surface 21, and the limit block 20 moves into the limit grooves 18 on both sides, so that the paddle 11 passes through the limit block 20 and reaches the bottom of the movable groove 10, thereby completing the air intake adjustment of the two gears. Example 2

[0037] like Figure 2 、 3 As shown in , 6 and 7, in addition to the features of the above embodiments, this embodiment further defines that: the housing 1 has the air inlet 6 opened on the side end face close to the condenser sheet 2, and the height of the baffle 17 is less than the total height of the air inlet 6.

[0038] like Figure 3 and Figure 6 As shown, when the relative humidity of the use environment reaches 95%, such as a bathroom, the paddle 11 is toggled to control the baffle 17 to move upward until it blocks the lower half of the air inlet 6. At this time, the air will enter the dehumidifier from the upper half of the air inlet 6, reach the upper half of the condensing sheet 2, and flow from the top to the bottom along the condensing sheet 2, thereby increasing the contact area and time between the air and the condensing sheet 2. After the air fully dissipates heat, the temperature of the condensing sheet 2 is increased, so that the temperature difference between the condensing sheet 2 and the outside air is reduced, reaching the optimal temperature difference value of 8.5°C under the relative humidity. At this time, the water vapor in the air is fully condensed to form water droplets, and the dehumidification efficiency of the dehumidifier is maximized.

[0039] like Figure 2 and Figure 7 As shown, when the relative humidity of the use environment is switched to 60%, such as the bedroom, the paddle 11 is turned to control the baffle 17 to continue to move upward until it blocks the middle part of the air inlet 6, leaving the upper and lower inlets. At this time, the total air inlet area remains unchanged, and the baffle 17 disperses the flow direction of the air, so that the air is divided into two. At this time, the air will flow in from the upper inlet of the air inlet 6 to the upper part of the condenser 2, and flow from the lower inlet of the air inlet 6 without passing through the condenser 2, so that half of the air is in contact with the condenser 2, and the other half of the air is not in contact with the condenser 2, reducing the contact area and time between the air and the condenser 2, so that the temperature of the condenser 2 is also reduced accordingly. At this time, the temperature difference between the condenser 2 and the external air will increase, reaching the optimal temperature difference value of 20°C under the relative humidity. Under this temperature difference condition, the dehumidification efficiency of the dehumidifier reaches the highest. Example 3

[0040] like Figure 4 、 5 As shown in Figures 8 and 9, in addition to the features of the above embodiments, this embodiment further defines that: the air inlet 6 is provided on the side end face of the housing 1 close to the condensing sheet 2 and the side end face close to the fan 4, and the air regulating component 7 is located at the air inlet 6 close to the fan 4, and the air inlet 6 close to the condensing sheet 2 is in a normally open state, and the height of the baffle 17 is equal to the total height of the air inlet 6.

[0041] like Figure 5 and Figure 9As shown, when the relative humidity of the use environment reaches 95%, such as a bathroom, the paddle 11 is toggled, and the control baffle 17 completely blocks the air inlet 6 near the side of the fan 4, so that the air enters completely from the air inlet 6 near the side of the condensing sheet 2. The total air inlet area remains unchanged, and all the air enters the condensing sheet 2, so that the contact area between the air and the condensing sheet 2 becomes larger. After the air fully dissipates heat, the temperature of the condensing sheet 2 is increased, so that the temperature difference between the condensing sheet 2 and the outside air is reduced, reaching the optimal temperature difference value of 8.5°C under the relative humidity. At this time, the water vapor in the air is fully condensed to form water droplets, and the dehumidification efficiency of the dehumidifier reaches the highest;

[0042] like Figure 4 and Figure 8 As shown, when switching to a usage environment with a relative humidity of 60%, such as a bedroom, the paddle 11 is toggled to control the baffle 17 to move downward so that the baffle 17 does not block the air inlet 6 close to the fan 4 side, forming a double opening. Since a part of the air is diverted into the air inlet 6, the air intake of the air inlet 6 close to the condensing plate 2 will become less, and the wind speed will also slow down accordingly, so that the air flow area flowing into the condensing plate 2 is reduced, thereby reducing the contact area between the air and the condensing plate 2, so that the temperature of the condensing plate 2 is maintained at a low temperature level, thereby increasing the temperature difference between the condensing plate 2 and the outside air, thereby reaching the optimal temperature difference of 20°C under the relative humidity, and the dehumidification efficiency of the dehumidifier is highest.

[0043] This embodiment also improves the heat dissipation efficiency of the heat sink 3 and the fan 4 by increasing the air intake of the air inlet 6 on the side close to the fan 4, thereby further improving the overall operating efficiency of the dehumidifier.

[0044] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0045] The above-described embodiments merely represent several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present utility model patent shall be determined by the appended claims.
