Description

Technical Field

[0001] This utility model relates to an air vent switch adjustment device and a dehumidifier. Background Technology

[0002] Currently, electrical appliances used to drive airflow (such as air purifiers and dehumidifiers) have an internal air cavity and an air inlet and an air outlet connected to the internal air cavity. The air outlet is usually in a normally open state. If the air outlet is too large, it is easy to cause a lot of dust accumulation when the air volume is small. If the air outlet is too small, it will cause excessive wind resistance and loud noise when the air volume is large.

[0003] Therefore, related technologies have developed a door panel at the air outlet and a drive mechanism to open or close the air outlet, thereby achieving the opening and closing of the air outlet or adjusting the opening size of the air outlet. However, the door panel is usually connected by a rotating mechanism, and the ordinary drive mechanism occupies a large space along the axial direction of the door panel's rotation axis, resulting in a smaller size of the air outlet along the axial direction of the door panel's rotation axis. This reduces the maximum opening size of the air outlet and affects the air volume. Utility Model Content

[0028] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0029] See Figures 1 to 3This utility model discloses an air vent switch adjustment device, comprising: a mounting body 100, an air outlet 101 provided on the mounting body 100, a narrow side region between the opposite sides of the air outlet 101 and the outline edge of the mounting body 100, a door panel 200 for adjusting the opening size of the air outlet 101 rotatably connected to one side of the mounting body 100, the door panel 200 having a rotating shaft 210 located within the narrow side region, a motor 300 provided on one side of the air outlet 101, and a transmission assembly 400 located within the narrow side region between the output shaft of the motor 300 and the rotating shaft 210.

[0030] The above-described air vent switch adjustment device uses the forward and reverse rotation of the output shaft of the motor 300 to drive the door panel 200 to rotate relative to the air outlet 101 through the transmission component 400, thereby adjusting the opening size of the air outlet 101. The transmission component 400 is located within the narrow side area between the air outlet 101 and the outline edge of the mounting body 100, and the motor 300 is located on the side of the air outlet 101. Without changing the size and specifications of the electrical appliance, the maximum opening size of the air outlet 101 will not be reduced, thus ensuring the air volume.

[0031] See Figure 1 and Figure 2In some embodiments of this utility model, the output shaft of the motor 300 and the rotating shaft 210 are parallel to each other. The transmission assembly 400 includes a first connecting rod 410 fixedly connected to the rotating shaft 210, a second connecting rod 420 fixedly connected to the output shaft of the motor 300, and a linkage rod 430 whose two ends are respectively rotatably connected to the first connecting rod 410 and the second connecting rod 420. The first connecting rod 410, the linkage rod 430 and the second connecting rod 420 are stacked and arranged in the narrow side region along the width direction of the narrow side region. It should be noted that when the output shaft of the motor 300 rotates, it drives the second link 420 to rotate. When the second link 420 rotates, it drives the first link 410 to rotate through the linkage 430, thereby driving the door panel 200 to rotate around the pivot 210. That is, the mounting body 100, the second link 420, the linkage 430 and the first link 410 are connected in sequence to form a planar four-bar linkage. The transmission component 400 of this structure occupies a small thickness in the narrow side area, which is conducive to maximizing the size of the air inlet, thereby ensuring the maximum air volume and expanding the opening adjustment range of the air outlet 101. Of course, in other embodiments, the transmission assembly 400 may also be configured as follows: a gear is provided on the rotating shaft 210, and a rack that meshes with the gear is slidably provided on the mounting body 100. The output shaft of the motor 300 is parallel to the rack, and a threaded rod is provided on the output shaft of the motor 300. The rack has a threaded through hole that mates with the threaded rod along its length. The motor 300 drives the threaded rod to rotate so as to drive the rack to slide back and forth, thereby driving the rotating shaft 210 on the gear to rotate in both directions.

[0032] See Figure 2 In some embodiments of this utility model, the first connecting rod 410 and the second connecting rod 420 are of equal length, and the mounting body 100, the first connecting rod 410, the linkage rod 430, and the second connecting rod 420 form a parallelogram mechanism. Due to its symmetry, the parallelogram mechanism has a simpler structure than a conventional four-bar linkage, is easier to manufacture and assemble, and can achieve constant speed transmission with smooth motion transmission.

[0033] In some embodiments of this utility model, in order to limit the angle of the door panel 200 when it is opened and closed, and to avoid the situation where the door panel 200 is not fully opened or closed due to the rotation of the motor 300 alone, the mounting body 100 is provided with an angle limiting structure that contacts the first connecting rod 410 or the second connecting rod 420.

[0034] See Figure 3In some embodiments of this utility model, the angle limiting structure includes a first limiting surface 510 and a second limiting surface 520 formed on the mounting body 100 and arranged face to face. A triangular limiting groove is defined between the first limiting surface 510 and the second limiting surface 520. The end of the first connecting rod 410 is provided with a first pivot 411. One end of the linkage rod 430 is provided with a first through hole corresponding to the first pivot 411. The first pivot 411 is located within the triangular limiting groove so that it can rotate to abut against the first limiting surface 510 or the second limiting surface 520. Understandably, when the motor 300 drives the first pivot 411 to swing to abut against the first limiting surface 510, the door panel 200 is at its maximum opening angle. When the motor 300 drives the first pivot 411 to swing to abut against the second limiting surface 520, the door panel 200 is in a closed state, effectively preventing jamming of the planar four-bar linkage composed of the mounting body 100, the second connecting rod 420, the linkage rod 430, and the first connecting rod 410.

[0035] See Figure 1 and Figure 2 In some embodiments of this utility model, the shape of the air outlet 101 and the shape of the door panel 200 are both rectangular. A side ear 220 is provided at each end of one long side of the door panel 200. The rotating shaft 210 includes two shaft ends respectively formed on the two side ear portions 220, with the shaft ends protruding from the long side of the door panel 200. The first connecting rod 410 is formed on one of the side ear portions 220. A socket 610 is provided in the narrow side region at one end of the door panel 200 for inserting one of the shaft ends. An opening groove 620 is provided in the narrow side region at the other end of the door panel 200 for the other shaft end to move in and out. A support block 630 is installed at the opening groove 620 to prevent the shaft end from disengaging from the opening groove 620. It is understood that the housing of an appliance is generally a regular rectangular body, and the rectangular shape of both the air outlet 101 and the door panel 200 is beneficial for fully utilizing the area of ​​one side panel of the housing. During assembly, one shaft end of the door panel 200 is inserted into the insertion hole 610, and the other shaft end enters along the entrance of the opening slot 620. Then, the support block 630 is installed and fixed to prevent the door panel 200 from falling off. Moreover, the output shaft of the motor 300 only needs to drive one of the shaft ends to rotate to drive the door panel 200 to rotate.

[0036] See Figure 1In some embodiments of this utility model, in order to make the exhaust quieter and smoother and to alleviate the turbulence phenomenon caused by large air volume, a long strip plate 230 parallel to the door panel 200 is provided on the surface of the door panel 200 facing the air outlet 101. A plurality of stiffening plates 240 are connected between the long strip plate 230 and the door panel 200 and are arranged at intervals along the length direction of the long strip plate 230. The stiffening plates 240 extend along the width direction of the door panel 200. An air guide duct 250 is defined between the door panel 200, the long strip plate 230 and two adjacent stiffening plates 240.

[0037] See Figure 1 and Figure 2 In some embodiments of this utility model, the mounting body 100 is provided with a receiving groove 103 opposite to the air outlet 101. An exhaust grille 102 is provided at the bottom of the receiving groove 103. When the door panel 200 closes the air outlet 101, the elongated plate 230, the reinforcing rib 240, and the air duct 250 are all located within the receiving groove 103, preventing the door panel 200 from protruding from the surface of the mounting body 100. Furthermore, the exhaust grille 102 helps reduce dust accumulation, and a filter element can be placed on the exhaust grille 102 to clean the ambient air.

[0038] See Figure 2 In some embodiments of this utility model, the mounting body 100 includes a lower housing 110 and a light-transmitting upper housing 120 detachably mounted above the lower housing 110. An air outlet 101 penetrates both the lower housing 110 and the upper housing 120, forming a flat space on one side of the air outlet 101 between the lower housing 110 and the upper housing 120. A control circuit board 700 and a display module 710 are housed within this flat space. The motor 300 is connected to the control circuit board 700 and located within the flat space. It is understood that the display module 710 displays information through the upper housing 120, and the control circuit board 700 is equipped with corresponding touch buttons. Users can operate the touch buttons on the surface of the upper housing 120 to control the opening angle of the door panel 200.

[0039] This utility model also discloses a dehumidifier, including the air outlet switch adjustment device of any of the above technical solutions; the dehumidifier uses the motor 300 to drive the door panel 200 to rotate relative to the air outlet 101 through the transmission component 400 when the motor 300 rotates, thereby adjusting the opening size of the air outlet 101. The transmission component 400 is located within the narrow side area and the motor 300 is located on the side of the air outlet 101. When the size and specifications of the dehumidifier remain unchanged, the maximum opening size of the air outlet 101 will not be reduced, thereby ensuring the air volume.

[0040] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above 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.

[0041] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
