Description

Technical Field

[0001] The utility model relates to the field of fresh air air conditioners, in particular to a fresh air valve component, a fresh air module and an air conditioner. Background Art

[0002] When the air conditioner is turned on in a room for a long time, the indoor air will become polluted and the oxygen content will decrease. People staying in the above environment will often experience adverse reactions such as dizziness and chest tightness.

[0003] In order to solve the above problems, more and more air conditioners have built-in fresh air functions. By turning on the built-in fresh air module, fresh air from the outdoor side can be transported into the room through the fresh air duct to improve the indoor air quality.

[0004] However, there are some problems with the fresh air module: the fresh air duct connects the indoor and outdoor sides. If the wind is strong outside, the air can easily flow back into the indoor side through the fresh air duct, causing the indoor temperature to change and generating whistling sounds, which affects the user experience. At the same time, small animals such as mosquitoes can easily crawl into the fresh air module through the fresh air duct, causing blockage and odor, affecting the performance of the air conditioner. Utility Model Content

[0005] In order to solve the above-mentioned technical problems, the purpose of the utility model is to provide a fresh air valve assembly, a fresh air module, and an air conditioner. Under the premise of not affecting the fresh air function, the valve assembly can automatically open and close with the start and stop of the fresh air function, thereby solving the problems of air backflow, mosquitoes and other small animals crawling into the fresh air module through the fresh air duct, etc.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical solutions:

[0007] A fresh air valve assembly is installed on a fresh air module, comprising a valve cover, a drive motor group and a valve, the fresh air module has an air inlet, the valve is rotatably arranged at the air inlet and can open or close the air inlet, the drive motor group is fixedly installed on the fresh air module, the drive motor group is connected to the valve and can drive the valve to rotate, the valve cover is fixedly arranged at the air inlet of the fresh air module, and the valve is located between the valve cover and the air inlet. When the valve is closed under the drive of the drive motor group, the air on the outdoor side will not flow back into the indoor side, and small animals such as mosquitoes cannot crawl into the fresh air module through the fresh air duct.

[0008] Preferably, the valve comprises a first door plate, a second door plate and a rotating shaft, the first door plate and the second door plate are semicircles with the same diameter, the first door plate and the second door plate are connected by a rotating shaft and are staggered, and an axis hole is provided at one end of the rotating shaft; two symmetrical rotating shaft installation positions are provided at the air inlet, and both ends of the rotating shaft of the valve are respectively mounted at the rotating shaft installation positions of the air inlet, and the motor shaft in the driving motor group is connected to the axis hole on the valve.

[0009] Preferably, the air inlet is also provided with a valve opening limit rib and a valve closing limit rib. When the driving motor group drives the valve to open to the maximum position, the valve and the valve opening limit rib abut against each other; when the driving motor group drives the valve to close, the valve and the valve closing limit rib abut against each other. This ensures that the valve can move to the specified position when closing or opening, improves the sealing performance, and ensures the air intake.

[0010] Preferably, the rotating shaft installation position at the air inlet is formed by two rotating shaft limiting ribs arranged opposite to each other, and the end limit of the rotating shaft on the valve is arranged between the two rotating shaft limiting ribs.

[0011] Preferably, the valve cover is symmetrically provided with two axis-center limiting parts on one side close to the valve. When the valve cover is installed at the air inlet, the axis-center limiting part of the valve cover is located in the rotating shaft installation position at the air inlet and is combined with the rotating shaft installation position to form a complete axis hole, so that the rotating shaft of the valve is limited by the valve cover and the air inlet. By combining the air inlet of the fresh air module and the valve cover to form a complete axis hole, the installation of the valve is convenient, and because the axis-center limiting part of the valve cover is located in the rotating shaft installation position at the air inlet, the concentricity of the two axis holes is guaranteed, and the smooth rotation of the valve is guaranteed.

[0012] Preferably, the driving motor group includes a motor base and a driving motor, the motor base is fixedly arranged on the fresh air module, the driving motor is fixedly arranged on the motor base, and the motor shaft on the driving motor is connected to the valve.

[0029] like Figures 2 to 6 A fresh air valve assembly is shown, which is installed on a fresh air module 1, and includes a valve cover 11, a drive motor group 12 and a valve 13. The fresh air module 1 has an air inlet 101, and the valve 13 is rotatably arranged at the air inlet 101 and can open or close the air inlet 101. The drive motor group 12 is fixedly installed on the fresh air module 1, and the drive motor group 12 is connected to the valve 13 and can drive the valve 13 to rotate. The valve cover 11 is fixedly arranged at the air inlet 101 of the fresh air module 1, and the valve 13 is located between the valve cover 11 and the air inlet 101. In this way, when the fresh air function is turned off, after the valve 13 is closed under the drive of the drive motor group 12, the air on the outdoor side will not flow back into the indoor side, and small animals such as mosquitoes cannot crawl into the fresh air module through the fresh air duct; when the fresh air function is turned on, the valve 13 is opened under the drive of the drive motor group 12 to ensure that the air inlet 101 of the fresh air module 1 can enter the air.

[0030] like Figure 5As shown, the valve 13 includes a first door plate 131, a second door plate 132 and a rotating shaft 133. The first door plate 131 and the second door plate 132 are semicircles with the same diameter. The first door plate 131 and the second door plate 132 are connected by the rotating shaft 133 and are staggered. An axis hole 1331 is provided at one end of the rotating shaft 133. Two symmetrical rotating shaft installation positions are provided at the air inlet 101. Both ends of the rotating shaft 133 of the valve 13 are respectively mounted at the rotating shaft installation positions of the air inlet 101. The motor shaft 123 in the driving motor group 12 is connected to the axis hole 1331 on the valve 13.

[0031] In order to obtain the maximum air intake when the valve 13 is opened and to achieve a good sealing effect when the valve 13 is closed, a valve opening limit rib 103 and a valve closing limit rib 104 are also provided at the air inlet 101. When the driving motor group 12 drives the valve 13 to open to the maximum position, the valve 13 abuts against the valve opening limit rib 103; when the driving motor group 12 drives the valve 13 to close, the valve 13 abuts against the valve closing limit rib 104. This ensures that the valve 13 can move to the specified position when closed or opened, improves the sealing performance, and ensures the air intake. Generally speaking, when the valve 13 is opened, the valve 13 is set at 90 degrees to the air inlet 101 of the fresh air module 1, thereby ensuring that the maximum air intake is obtained when the valve 13 is opened.

[0032] The shaft installation position at the air inlet 101 is formed by two shaft limiting ribs 102 arranged opposite to each other, the two shaft limiting ribs 102 are connected in an arc shape, and the end limit of the shaft 133 on the valve 13 is set between the two shaft limiting ribs 102 to prevent the valve 13 from axial movement.

[0033] like Figure 6 As shown, two axis-center limiting parts 111 are symmetrically protruded on one side of the valve cover 11 near the valve 13. When the valve cover 11 is installed at the air inlet 101, the axis-center limiting part 111 of the valve cover 11 is located in the rotating shaft installation position at the air inlet 101 and is combined with the rotating shaft installation position to form a complete axis hole, so that the rotating shaft 133 of the valve 13 is limited by the valve cover 11 and the air inlet 101. By combining the air inlet 101 of the fresh air module 1 and the valve cover 11 to form a complete axis hole, the installation of the valve 13 is convenient, and because the axis-center limiting part of the valve cover 11 is located in the rotating shaft installation position at the air inlet 101, the concentricity of the two axis holes is guaranteed, and the smoothness of the valve rotation is guaranteed.

[0034] In the utility model, the valve cover 11 is arranged in a tubular shape. In other embodiments, a valve closing limiting rib may be arranged on the valve cover 11, so that when the valve 13 is closed, the valve 13 has a better sealing effect on the air inlet 101; or, the valve closing limiting rib may be arranged on one of the valve cover 11 and the air inlet 101 of the fresh air module 1. A clamping groove 112 is arranged on the valve cover 11, and the valve cover 11 is positioned and clamped outside the rotating shaft limiting rib 102 of the air inlet 101 on the fresh air module 1 through the clamping groove 112, thereby providing a limiting effect when the valve cover 11 is installed, and can also ensure that the axis of the rotating shaft 133 on the valve 13 is kept within a reasonable deviation range to prevent the rotating shaft 133 of the valve 13 from being stuck.

[0035] like Figure 3 and Figure 4 As shown, the driving motor group 12 includes a motor base 121 and a driving motor 122. The motor base 121 is fixedly arranged on the fresh air module 1. The driving motor 122 is fixedly arranged on the motor base 121. The motor shaft 123 on the driving motor 122 is connected to the valve 13. The motor base 121 can protect the driving motor 122 and prevent the condensed water of the air conditioner from directly dripping on the driving motor 122, causing the driving motor 122 to corrode and rust.

[0036] The utility model also discloses a Figure 2 The fresh air module comprises a fresh air valve assembly as described above.

[0037] The utility model also discloses an air conditioner, comprising a fresh air module as described above, such as Figure 1 As shown, the fresh air module is installed at the lower part of the air conditioner cabinet.
