Description

Technical Field

[0001] This utility model relates to the field of dehumidifier technology, and in particular to a swing device and a dehumidifier. Background Technology

[0002] Dehumidifiers, as key devices for regulating indoor air humidity, are widely used in homes, offices, and various industrial settings. They circulate air, condense moisture, and return the dried air to the room. During this process, the comfort and efficiency of the airflow pattern directly affect the user experience and the device's performance. Currently, most mainstream dehumidifiers on the market have a single airflow pattern, supporting only vertical or horizontal oscillation.

[0003] The limitation of existing technology lies in the fact that for dehumidifiers that only support vertical airflow, users cannot select the horizontal airflow mode according to their actual needs (such as needing to quickly and evenly dehumidify the entire width of the room or avoid blowing air onto specific areas). This single airflow direction limits the optimization of airflow distribution, which may lead to uneven indoor humidity, affecting dehumidification efficiency and user experience. To compensate for the lack of horizontal airflow function, some manufacturers achieve horizontal airflow by adding an independent horizontal airflow mechanism to the air duct outlet; this mechanism is usually driven by another motor to control the rotation of the horizontal guide vanes. However, this method has several drawbacks. The added mechanical components are located on the core airflow path of the duct outlet, and their physical structure obstructs the airflow. This obstruction leads to a certain degree of air pressure loss and increases wind resistance. To maintain the same air volume, the fan needs to operate at a higher speed, which increases the overall power consumption of the machine and is not conducive to energy efficiency. In addition, it increases the noise during operation. The increased wind resistance itself will generate more eddies and turbulence, producing aerodynamic noise. This will affect the comfort of users in quiet home or office environments. Utility Model Content

Detailed Implementation

[0026] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention. Example 1

[0027] Reference Figures 1 to 8As shown, the swing device of this utility model can be installed in dehumidifiers, air conditioners and other gas interaction devices to increase and expand the flow range of the swing airflow, thereby improving dehumidification or ventilation efficiency and bringing a better user experience.

[0028] The swing device includes a base plate 1, on which a vent 10 is provided. The base plate 1 has a first end face 11 and a second end face 12 along its thickness direction. During operation, the dry air to be output is formed on the side where the second end face 12 is located, flows out from the side where the second end face 12 is located, and is discharged to the side where the first end face 11 is located through the vent 10.

[0029] The swing device further includes a first swing unit, which includes a first mounting base 20, a first blade assembly 21, a first transmission assembly 22, and a first driving member 23. The first mounting base 20 is disposed on the first end face 11, the first blade assembly 21 is movably mounted on the first mounting base 20, and the first driving member 23 is connected to the first blade assembly 21 through the first transmission assembly 22 to drive the first blade assembly 21 to swing along a first direction.

[0030] The first blade assembly 21 is positioned opposite to the vent 10 to effectively control the direction of gas flow; It should be noted that the first transmission component 22, the first driving component 23 and the vent 10 are staggered along the thickness direction of the substrate 1. This can also be understood as the projections of the first transmission component 22 and the first driving component 23 not overlapping with the projection of the vent 10 along the thickness direction of the substrate 1. This arrangement ensures that the positions of the first transmission component 22 and the first driving component 23 are located outside the air duct and away from the area where the air outlet is located. This avoids aerodynamic noise caused by increased wind resistance when the first transmission component 22 and the first driving component 23 are working, effectively preventing the generation of additional noise.

[0031] The swing device further includes a second swing unit 3, which includes a second blade assembly 31 and a second drive member 32. The second blade assembly 31 is rotatably connected to the first end face 11, and the end of the second blade assembly 31 passes through the vent 10 and extends to the side where the second end face 11 is located.

[0032] The second driving member 32 is mounted on the first end face 11, and the output end of the second driving member 32 is connected to the second blade assembly 31 to drive the second blade assembly 32 to swing along the second direction.

[0033] In this embodiment, the first direction is defined as the left-right direction, and the second direction is defined as the up-down direction; the first direction is perpendicular to the second direction.

[0034] Therefore, it can be seen that the swing device protected by this utility model includes a base plate, a first swing unit, and a second swing unit. The first and second swing units are mounted on the base plate. The first swing unit can swing in the left and right direction, while the second swing unit can swing in the up and down direction. The up and down swing and the left and right swing can be controlled independently to meet different swing needs. Therefore, this utility model can effectively increase the airflow range, improve dehumidification and ventilation efficiency, and bring different user experiences. In addition, while realizing multi-dimensional and selectable air supply modes, it can effectively overcome the high wind resistance and high noise problems caused by traditional left and right swing devices, thus achieving a good balance between improving user experience and ensuring efficient and quiet operation of the equipment.

[0035] In a preferred embodiment, the first blade assembly 21 includes a plurality of first blades 210 spaced apart along the first direction. Specifically, each first blade 210 extends along the second direction, one end of each first blade 210 along the second direction is rotatably connected to the first mounting base 20, and the other end of each first blade 210 along the second direction is connected to the first transmission assembly 22.

[0036] Preferably, for the purpose of improving the uniformity of gas flow, the two adjacent first blades 210 can be set at equal intervals.

[0037] Further, the first transmission assembly 22 includes a drive link 220, a first link 221, and a second link 222. The first link 221 is movably connected to the output end of the first drive member 23 via the drive link 220, so as to move along the first direction under the drive of the first drive member 23. One end of the second link 222 is connected to the first link 221, and the other end of the second link 222 is connected to the first blade 210. It should be noted that there are multiple second links 222, and each second link 222 is configured to cooperate with one first blade 210. With this configuration, when the first link 221 moves along the first direction under the drive of the first drive member 23, it can synchronously drive multiple second links 222 to move, thereby driving the first blade 210 to rotate synchronously, realizing the left and right swing of the first blade 210.

[0038] In detail, the first connecting rod 221 includes a first body 2210 and a drive member mounting portion 2211 disposed on the first body 2210. The first body 2210 extends along the first direction. The drive member mounting portion 2211 includes a protrusion 22110 and a guide groove 22111. The protrusion 22110 is located in the middle of the first body 2210, and the guide groove 22111 is disposed on the protrusion 22110. The extending direction of the guide groove 22111 is perpendicular to the first direction. One end of the driving connecting rod 220 is slidably connected to the guide groove 22111.

[0039] With this configuration, the first driving member 23 can output power to the driving member mounting part 2211 through the driving link 220, and then drive the first link 221 to swing around the output end of the first driving member 23 through the driving member mounting part 2211, so as to synchronously drive the second link 222 to move. The guide groove 2213 can provide redundant space for the movement of the driving link 220 to a certain extent.

[0040] Furthermore, the first connecting rod 221 also includes mounting holes 2212, the number of which is not less than the number of the second connecting rods 222, and the plurality of mounting holes 2212 are spaced apart along the first direction in the first body 2210; one end of the second connecting rod 222 is fitted into the mounting hole 2212 by a fastener, and the other end of the second connecting rod 222 is connected to the first blade 210. The fasteners include, but are not limited to, bolts.

[0041] Traditional left-right swing mechanisms typically have a drive linkage at the air duct opening connecting the left and right fan blades, which increases the air resistance at the outlet and consequently increases the noise during operation. This invention employs a transmission connection between the first link 221, the second link 222, the drive link 220, and the first drive component 23, and positions the first transmission assembly 22 outside the air duct, thus avoiding the location of the air outlet and preventing the generation of additional noise.

[0042] It should be noted that, in order to facilitate installation and ensure the uniformity of the driving force received by the first connecting rod 221, the first driving member 23 is positioned to match the driving mounting part 2211, and the first driving member 23 is adjacent to the middle of the first connecting rod 221.

[0043] In a preferred embodiment, the first swing unit further includes a locking assembly disposed on the first mounting base 20 to limit the swing amplitude of the second link 222. Specifically, the locking assembly includes a first limiting plate 201 and a second limiting plate 202 disposed opposite to each other. When the second link 222 is driven to swing along the first direction, it can be limited by the first limiting plate 201 and the second limiting plate 202 respectively. When the second link 222 rotates to the leftmost position, the first limiting plate 201 blocks the second link 222 to prevent excessive rotation that could prevent it from returning to its original position; when the second link 222 rotates to the rightmost position, the second limiting plate 202 blocks the second link 222 to ensure the accuracy of the swing angle and prevent excessive rotation of the second link 222.

[0044] The locking assembly is provided in at least one set. Preferably, the locking assembly is provided in two sets, which are spaced apart along the first direction on the first mounting base 20, and the two sets of locking assemblies respectively cooperate with the two second connecting rods 222.

[0045] In a preferred embodiment, the second blade assembly 31 includes a second blade 310, a first connecting seat 311, and a second connecting seat 312, wherein the first connecting seat 311 and the second connecting seat 312 are respectively disposed at both ends of the second blade 310 along the first direction; The substrate 1 is provided with a mounting groove, the first connecting seat 311 is provided with a first connecting member, and the second connecting seat 312 is rotatably connected to the mounting groove through the first connecting member; the first connecting seat 311 is connected to the output end of the second driving member 32 so as to drive the second blade 310 to swing under the drive of the second driving member 32.

[0046] To ensure smooth airflow, a ventilation grille 203 is provided on the first mounting base 20, which is positioned opposite to the vent 10. Furthermore, the ventilation grille 203 also serves a protective function, preventing accidental contact with the vent 10 by the user and potential danger (such as direct contact with the dehumidifier's centrifugal fan blades).

[0047] In a preferred embodiment, the substrate 1 is further provided with a mounting port 13 for mounting a panel. The panel includes a touch display panel to facilitate data interaction and user operation.

[0048] In a preferred embodiment, the first driving component 23 includes, but is not limited to, a drive motor, and the second driving component 32 includes, but is not limited to, a drive motor.

[0049] To facilitate the assembly of the swing device into a dehumidifier or air conditioning unit, the edge of the base plate 1 is also provided with mounting clips 14. Multiple mounting clips 14 can be provided as needed to adapt to different devices. Example 2

[0050] This utility model also discloses a dehumidifier, which includes an air swing device as described in Embodiment 1, and the air swing device is detachably installed at the air outlet of the dehumidifier.

Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.
