[0021] In order to make the purpose, technical solutions and advantages of the present disclosure clearer, the technical solutions of the present disclosure will be clearly and completely described below in combination with the specific embodiments of the present disclosure and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present disclosure.

[0022] Combination Figure 1 to Figure 2 As shown, an embodiment of the present disclosure provides an air conditioner, including a fresh air device, which includes a fresh air outlet 12; the air conditioner also includes a downwind duct 6, and the fresh air outlet 12 is arranged on the duct wall of the downwind duct 6. The fresh air outlet 12 is provided with an air guide structure 7, and the air guide structure 7 is configured to control the opening and closing of the fresh air outlet 12 and the air volume, and is also configured to control the direction of the airflow in the downwind duct 6.

[0023] In the air conditioner of the disclosed embodiment, the fresh air outlet 12 of the fresh air device is located on the duct wall of the lower duct 6, and is provided with an air guide structure 7. The air guide structure 7 is movably arranged to control the opening and closing of the fresh air outlet 12 and the air volume according to the different working states of the air conditioner and the fresh air device, and can also guide the wind direction of the lower duct 10 of the air duct of the air conditioner, so as to control the size of the fresh air outlet and the distance of the air supply from the lower duct 10, thereby improving the user experience. At the same time, when the fresh air device is not in operation, the air guide structure 7 closes the fresh air outlet 12 to prevent dust and the like from entering, thereby ensuring the cleanliness of the interior of the fresh air device and improving the health experience of the fresh air device and the air conditioner.

[0024] In some embodiments, the wind guide structure 7 includes an air guide plate 8, which is rotatably connected to the fresh air outlet 12. A downwind outlet 10 is provided at the end of the downwind duct 6 along the airflow direction. The air guide plate 8 is connected to the upper edge of the fresh air outlet 12 along the airflow direction. The air guide plate 8 is configured to be able to open into the downwind duct 6. The air guide plate 8 guides the airflow flowing to the downwind outlet 10 toward the first side 802 of the downwind duct 6.

[0025] In the air conditioner of this embodiment, the air guide structure 7 adopts an air guide plate 8, and the air guide plate 8 can be opened toward the lower air duct 6. When the air guide plate 8 is opened, that is, partially extended into the lower air duct 6, since the airflow in the lower air duct 6 is blown from top to bottom and is substantially perpendicular to the horizontal plane, the first side surface 802 of the air guide plate 8 forms a certain angle with the airflow in the lower air duct 6, and the airflow will change its flow direction along the first side surface 802 of the air guide plate 8, thereby reducing the angle between the airflow and the horizontal plane. The airflow blowing out of the lower air outlet 10 along this direction will significantly increase the air supply distance compared to the airflow not guided by the air guide plate 8. When the lower air outlet 10 needs to supply air for a long distance, the angle of the air guide plate 8 can be adjusted to a larger angle, and the fresh air output volume is relatively large. When the lower air outlet 10 needs to supply air for a short distance and a wide range, the angle of the air guide plate 8 can be adjusted to a smaller angle, and the fresh air output volume is relatively small. The air supply angle and the fresh air output volume can be adjusted within a certain range according to different use environments.

[0026] In some embodiments, when the air guide plate 8 is in a closed state, the first side surface 802 of the air guide plate 8 is flush with the air duct wall of the lower air duct 6 .

[0027] In the present embodiment, since the fresh air outlet 12 of the fresh air device is arranged on the air duct wall of the downwind duct 6, in order to prevent the fresh air outlet 12 and the air guide structure 7 from affecting the normal air outlet of the downwind duct 6, the side of the air guide plate 8 is made to match and flush with the air duct wall of the downwind duct 6. When the air guide plate 8 is in the closed state, the air guide plate 8 is smoothly connected to the air duct wall, and the air guiding performance is similar to that of other parts of the air duct wall, and will not cause airflow loss in the downwind duct 6.

[0028] In some embodiments, the air guide structure 7 further includes an air guide motor 9 , which is configured to drive the air guide plate 8 to rotate around the upper edge of the fresh air outlet 12 .

[0029] In this embodiment, in order to realize automatic control of the air guide structure 7, an air guide motor 9 is used as the driving component of the air guide structure 7. The rotation angle of the air guide plate 8 is controlled by the rotation of the motor to realize the control of the fresh air outlet volume and the air supply distance of the downwind outlet 10, thereby achieving an intelligent control effect.

[0030] In some embodiments, the air guide plate 8 includes a rotating shaft portion 801, which is arranged on a second side surface 803 opposite to the first side surface 802. The rotating shaft portion 801 is protruded along the second side surface 803. The position of the rotating shaft portion 801 avoids the air duct wall of the lower air duct 6. The air guide plate 8 is rotatably installed on the fresh air outlet 12 through the rotating shaft portion 801. The air guide motor 9 is hinged to the rotating shaft portion 801. The air guide plate 8 is driven to rotate around the rotating shaft portion 801 by the air guide motor 9, so as to realize the opening and closing of the fresh air outlet 12 and adjust the air volume.

[0031] In the present embodiment, in order to make the edge of the first side 802 along the airflow direction as close to the air duct wall as possible during the opening and closing of the air guide plate 8, and at the same time reduce the difficulty of installing the air guide motor 9, the installation position of the air guide motor 9 avoids the air duct wall structure, and the shaft portion 801 protrudes from the second side 803, which meets the opening and closing trajectory of the first side 802 and is convenient for the installation of the air guide motor 9.

[0032] In some embodiments, the fresh air device includes a device shell, in which a fresh air driving chamber 1 and a dirty air driving chamber 2 are constructed. The fresh air driving chamber 1 and the dirty air driving chamber 2 are independent of each other. The fresh air exhaust outlet is connected to the fresh air driving chamber 1, and the fresh air driving chamber 1 is also connected to a fresh air inlet 11. The dirty air driving chamber 2 is respectively connected to a dirty air inlet 21 and a dirty air exhaust outlet 22. A first fan blade 13 is provided in the fresh air driving chamber 1, which is used to drive an airflow, such as fresh air in the external environment, into the fresh air driving chamber 1 via the fresh air inlet 11 and discharge it to the indoor space via the fresh air exhaust outlet 12. A second fan blade 23 is provided in the dirty air driving chamber 2, which is used to drive the indoor dirty air flow into the dirty air driving chamber 2 via the dirty air inlet 21 and discharge it to the outdoor environment via the dirty air exhaust outlet 22.

[0033] In this embodiment, the first fan blade 13 and the second fan blade 23 can drive fresh air and indoor polluted air respectively, so that the fresh air device can introduce fresh air from the external environment into the room while discharging indoor polluted air into the outdoor environment, thereby more efficiently improving the indoor air quality. At the same time, since the fresh air driving chamber 1 and the polluted air driving chamber 2 are constructed in the device shell at the same time, the overall structure of the fresh air device is more compact and occupies less space.

[0034] In some embodiments, the fresh air device also includes a first drive motor 31, which is a double-shaft motor. The first fan blade 13 and the second fan blade 23 are respectively mounted on the two ends of the power output shaft of the double-shaft motor, thereby making the structure of the fresh air device more compact and reducing the purchase cost of the drive motor. In addition, it can also simplify the design of the electrical control system.

[0035] In some embodiments, the fresh air inlet 11 corresponds to the fresh air inlet pipe 111, the dirty air outlet 22 corresponds to the dirty air outlet pipe 221, and a first damper 41 is provided between the fresh air inlet pipe 111 and the dirty air outlet pipe 221. The first damper 41 has a first position that connects the fresh air inlet pipe 111 with the dirty air outlet pipe 221 and cuts off the fresh air inlet pipe 111 and the dirty air outlet pipe 221 from the external environment, and a second position that cuts off the fresh air inlet pipe 111 and the dirty air outlet pipe 221. The outlet pipe 221 is used to connect with the fresh air duct and the dirty air duct between the indoor and outdoor areas respectively. The setting of the first damper 41 can form a controllable connection between the dirty air driving chamber 2 and the fresh air driving chamber 1, so that the fresh air device can realize internal circulation in the operation mode. For example, the indoor dirty air is introduced into the dirty air driving chamber 2 and then introduced into the fresh air driving chamber 1 and discharged. It can be understood that at this time, corresponding air purification components (such as filter components) are set on the air flow paths of the two so that air purification can be achieved by the dirty air internal circulation. The position switching of the first damper 41 can be controlled by the second drive motor 32.

[0036] In some embodiments, the device housing includes a fresh air exhaust channel, and the air guide motor 9 is installed on the outside of the wall of the fresh air exhaust channel.

[0037] In the air conditioner of this embodiment, the air guide motor 9 is installed on the outside of the wall of the fresh air exhaust channel, and the rotating shaft portion 801 of the air guide plate 8 also passes through the fresh air exhaust channel to the outside. The rotating shaft portion 801 is connected to the air guide motor 9, so that the air guide plate 8 is driven to rotate through the air guide motor 9.

[0038] It is easy for those skilled in the art to understand that, under the premise of no conflict, the above-mentioned advantageous methods can be freely combined and superimposed. The above are only preferred embodiments of the present disclosure and are not intended to limit the present disclosure. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present disclosure should be included in the protection scope of the present disclosure. The above are only preferred implementations of the present disclosure. It should be pointed out that for ordinary technicians in this technical field, several improvements and variations can be made without departing from the technical principles of the present disclosure, and these improvements and variations should also be regarded as the protection scope of the present disclosure.
