AI Technical Summary
The existing wall-mounted air conditioner has an unreasonable fresh air module structure design. The damper drive structure of the fresh air inlet and outlet is complicated, resulting in high cost and uneven fresh air output, which affects user comfort.
A transmission mechanism is used to drive the first and second air dampers to move synchronously. Through the combination of transmission gears, the first transmission component and the second transmission component, the fresh air inlet and the fresh air outlet are opened and closed at the same time, reducing the movement space of the dampers. The second air damper moves along the normal direction parallel to the fresh air outlet to guide the fresh air to diffuse evenly.
The size of the fresh air module has been reduced, the uniformity and comfort of the fresh air output have been improved, the cost has been reduced, and the discomfort of fresh air blowing directly on the human body has been reduced.

Abstract
Claims
1. A wall-mounted air conditioner, comprising: The main body, the main body includes: The housing has an internal cavity and a heat exchange inlet and a heat exchange outlet on its surface. An indoor heat exchanger is disposed within the accommodating cavity; A heat exchange fan is installed inside the volute duct of the main body and is located on the side of the indoor heat exchanger away from the heat exchange air inlet. Its characteristic is that it further includes: Fresh air volute, wherein a fresh air inlet and a fresh air outlet are formed on the fresh air volute; A drive motor, which is mounted on the fresh air volute; The first air damper is movably installed at the fresh air inlet and is used to open or close the fresh air inlet. The second air damper is movably installed at the fresh air outlet and is used to open or close the fresh air outlet. A transmission mechanism is provided, through which the drive motor drives the first damper and the second damper to move synchronously. The transmission mechanism includes: A transmission gear, which is dynamically coupled to the drive motor; The first transmission component is connected to the transmission gear and the first damper respectively; The second transmission component is connected to the transmission gear and the second damper respectively. The transmission gear drives the first damper to move along the normal direction perpendicular to the fresh air inlet through the first transmission component to open or close the fresh air inlet. At the same time, it drives the second damper to move along the normal direction parallel to the fresh air outlet through the second transmission component to open or close the fresh air outlet. When the second damper opens the fresh air outlet, the second damper separates from the fresh air outlet to guide fresh air to flow into the room from the gap between the fresh air outlet and the second damper.
2. The wall-mounted air conditioner according to claim 1, wherein The fresh air outlet and the fresh air inlet are distributed front and back along the thickness direction of the main body, and the fresh air outlet is located below the main body in the height direction of the main body, so as to guide the fresh air to flow downward out of the fresh air outlet.
3. The wall-mounted air conditioner according to claim 1, wherein The first transmission component includes a first rack, which is connected to the first damper and is also dynamically coupled to the transmission gear. The second transmission component includes a second rack, which is connected to the second damper and is dynamically coupled to the transmission gear.
4. The wall-mounted air conditioner according to claim 3, wherein The fresh air volute is provided with an installation groove, the opening of the installation groove faces the fresh air outlet, and the bottom of the installation groove is provided with a second notch; The second transmission component is movably inserted through the second notch, and the outer end of the second transmission component extends through the second notch into the mounting groove and is connected to the second damper. The portion of the second transmission component outside the mounting groove is provided with the second rack, and the portion of the second transmission component in the mounting groove is provided with a limiting component. The outer diameter of the limiting component is larger than the inner diameter of the second notch. When the limiting component contacts the bottom of the mounting groove, the second damper closes the fresh air outlet.
5. The wall-mounted air conditioner according to claim 4, wherein The second transmission component includes a first connecting part and a second connecting part. The first connecting part, the limiting member and the second connecting part are connected in sequence. The portion of the first connecting part that passes through the second notch and is located outside the mounting groove is provided with the second rack. The second connecting part is detachably connected to the second damper.
6. The wall-mounted air conditioner according to claim 3, characterized in that, The transmission gear includes a first gear and a second gear that are coaxially arranged and connected. The first rack is dynamically coupled to the first gear, and the second rack is dynamically coupled to the second gear.
7. The wall-mounted air conditioner according to claim 6, wherein The pitch circle diameter of the first gear is smaller than that of the second gear; the first damper is provided with a clearance groove to avoid the second transmission component, the clearance groove being open at both ends perpendicular to the moving direction of the first damper, and when both the fresh air inlet and the fresh air outlet are closed, a portion of the second transmission component is located within the clearance groove; or, The pitch circle diameter of the first gear is larger than that of the second gear; the first damper is provided with a clearance groove to avoid the second transmission component, the opening of the clearance groove facing the transmission gear, and when both the fresh air inlet and the fresh air outlet are closed, at least a portion of the second transmission component is located in the clearance groove.
8. The wall-mounted air conditioner according to claim 6, wherein The first damper is provided with a clearance groove to avoid the second transmission component. The length of the clearance groove opening along the moving direction of the first damper is L1, the depth of the clearance groove is L2, the stroke of the first damper is S1, and the stroke of the second damper is S2, satisfying: S1 / S2≤L1 / L2≤1.5×(S1 / S2).
9. The wall-mounted air conditioner according to any one of claims 1-8, characterized in that, The first transmission component is also provided with a first limiting part, and the second transmission component is provided with a second limiting part. When the second limiting part is engaged with the first limiting part, the first damper closes the fresh air inlet, and the second damper closes the fresh air outlet.
10. The wall-mounted air conditioner according to any one of claims 1-8, characterized in that, The fresh air volute is provided with a first guide member, which extends along a direction perpendicular to the normal of the fresh air inlet, and the first damper slides in cooperation with the first guide member; and / or, The fresh air volute is provided with a second guide member, which extends along a normal direction parallel to the fresh air outlet, and the second transmission member slides in cooperation with the second guide member.
