DETAILED DESCRIPTION

[0033] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means intended to limit the present invention and its application or use. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] As shown in the accompanying drawings, an embodiment of the present invention provides an air inlet and outlet structure, comprising: a housing 10, the housing 10 having an air duct 11 and an air outlet 12 connected to the air duct 11; a shielding portion 20, movably arranged on the housing 10, the shielding portion 20 having a blocking position for blocking the air outlet 12 and a avoiding position for avoiding the air outlet 12, wherein the blocking position is located at the air outlet 12, and the avoiding position is located in the cavity of the housing 10. The air outlet 12 in the air inlet and outlet structure can be used for air intake or air outlet, and the air inlet and outlet structure can be used for air intake or air outlet in an air conditioner. When the shielding portion 20 is in the blocking position, the air outlet 12 is not connected to the outside of the housing 10 to play a protective role, and when the shielding portion 20 is in the avoiding position, the air outlet 12 is connected to the outside of the housing 10 to intake or exhaust air; a filter portion, movably arranged on the shielding portion, and the filter portion is used to filter the wind entering the air duct.

[0035] The technical solution of this embodiment is applied to provide an air inlet and outlet structure, in which a housing 10 and a shielding part 20 are provided, the housing 10 has an air duct 11 and an air outlet 12 connected to the air duct 11, the shielding part 20 is movably provided on the housing 10, and the shielding part 20 has a blocking position for blocking the air outlet 12 and a avoiding position for avoiding the air outlet 12, wherein the blocking position is located at the air outlet 12, and the avoiding position is located in the cavity of the housing 10. When the shielding part 20 is in the blocking position, the air outlet 12 is closed, and when the shielding part 20 is in the avoiding position, the air outlet 12 is opened. Through the above arrangement, when the shielding part 20 moves to the inside of the cavity of the housing 10, the air outlet 12 can be opened, so that air can enter or exit through the air outlet 12. Since the shielding part 20 is located inside the housing 10 when the air outlet 12 is opened, and does not extend outside the housing 10, the aesthetics of the air conditioner will not be affected. The shielding portion 20 is used to replace the existing air guide plate, thereby avoiding the problem that the protruding air guide plate affects the aesthetics of the air conditioner.

[0036] Moreover, the filter part 30 is movably arranged on the shielding part 20, and the filter part 30 is used to filter the wind entering the air duct 11. The filter part 30 is arranged on the shielding part 20, so that the filter part 30 and the shielding part 20 become an integrated assembly structure, which can reduce the number of parts, facilitate assembly, and make the structure compact. Moreover, since the filter part 30 is movable, the functions of the air inlet and outlet structure and the applicable situations are enriched. For example, when the air outlet 12 is used for air intake, the filter part 30 moves to the wind flow path in the air duct 11 for filtering, and when the air outlet 12 is used for air outlet, the filter part 30 moves to a position to avoid wind flow to ensure smooth air outlet. In this embodiment, the movement of the filter part 30 relative to the shielding part 20 can be other forms of movement such as translation and rotation.

[0037] In this embodiment, when the shielding portion 20 is in the avoidance position, the air outlet 12 can be switched to an air intake state or an air outlet state, that is, when the air outlet 12 is open, the air outlet 12 can be selectively used for air intake or air outlet. Among them, when the air outlet 12 is in the air intake state, the filter portion 30 is located on the wind flow path in the air duct 11 to filter the wind entering the air duct 11; when the air outlet 12 is in the air outlet state, the filter portion 30 leaves the wind flow path to avoid the wind output from the air duct 11. Through the above arrangement, when the air outlet 12 is used for air intake, the filter portion 30 can play a filtering role, and when the air outlet 12 is used for air outlet, the filter portion 30 plays a avoiding role to ensure smooth air outlet. The air intake and outlet structure is flexible to use and has a wide range of applications.

[0038] Optionally, the shielding portion 20 can be swung and maintained at different positions, so that when the air outlet 12 is used to discharge air, the air outlet direction can be adjusted by changing the angle of the shielding portion 20, thereby playing a role in guiding the air. Alternatively, the shielding portion 20 can be swung back and forth to achieve swinging air discharge in the required indoor heat exchange area.

[0039] In this embodiment, the filter part 30 is rotatably arranged on the shielding part 20, and the filter part 30 has a closed position attached to the shielding part 20 and an open position with a preset angle between the shielding part 20, wherein when the shielding part 20 is in the blocking position, the filter part 30 is in the closed position; when the air outlet 12 is in the air intake state, the filter part 30 is in the open position to filter the wind entering the air duct 11; when the air outlet 12 is in the air outlet state, the filter part 30 is in the closed position to avoid the wind output from the air duct 11. When the air outlet 12 is in the air intake state or the air outlet state, the shielding part 20 is in the avoidance position. In this way, the position of the filter part 30 can be changed by rotating the filter part 30, so as to filter the wind entering the air duct 11 or avoid the wind output from the air duct 11. Among them, when the shielding part 20 is in the blocking position and the air outlet 12 is in the air outlet state, the filter part 30 is in the closed position attached to the shielding part 20, so that the occupied space of the filter part 30 can be reduced. In this embodiment, when the shielding portion 20 is located at the blocking position and the air outlet 12 is in the air outlet state, the filter portion 30 is located at a different position relative to the housing 10 .

Through the above arrangement, when the filter part 30 is attached to the shielding part 20, the surface of the filter part 30 on the side away from the first avoidance groove 21 is flush with the outer surface of the shielding part 20, so that when the shielding part 20 and the filter part 30 are at the air outlet 12, the structural parts can be prevented from protruding from the housing 10, ensuring the aesthetic appearance, and when the shielding part 20 and the filter part 30 are located in the cavity of the housing 10, the flow of wind can be prevented from being disturbed, reducing resistance.

[0054] Optionally, the first arc-shaped rack 41 has a push-out state and a retracted state. When the first arc-shaped rack 41 is in the push-out state, the mushroom-shaped piece abuts against one end of the first waist-shaped hole 26 for position limiting. When the first arc-shaped rack 41 is in the retracted state, the mushroom-shaped piece abuts against the other end of the first waist-shaped hole 26 for position limiting. Correspondingly, the second arc-shaped rack 51 has a push-out state and a retracted state.

When the second arc-shaped rack 51 is in the retracted state, the mushroom-shaped piece abuts against the other end of the second waist-shaped hole 34 for position limiting.

[0055] like Figures 1 to 6As shown, when the air outlet 12 is closed, the first arc-shaped rack 41 and the second arc-shaped rack 51 are both in the pushed-out state; when the air outlet 12 is in the air outlet state, the first arc-shaped rack 41 and the second arc-shaped rack 51 are both in the retracted state; when the air outlet 12 is in the air intake state, the first arc-shaped rack 41 is in the retracted state, and the second arc-shaped rack 51 is in the pushed-out state.

[0056] like Figure 6 As shown, there are two air vents 12, which are respectively located at the two ends of the air duct 11, two shielding parts 20, which are arranged one-to-one with the two air vents 12, and two filtering parts 30, which are arranged one-to-one with the two shielding parts 20; wherein, the two air vents 12 are respectively the first air vent and the second air vent, and when the first air vent is in the air intake state, the second air vent is in the air outlet state; when the first air vent is in the air outlet state, the second air vent is in the air intake state. Through the above arrangement, any one of the two air vents 12 can be selected to intake air, and the other of the two air vents 12 can be used to discharge air, thereby improving the function and flexibility of the air inlet and outlet structure and the air conditioner using the air inlet and outlet structure, and meeting different usage requirements. Moreover, by setting two shielding parts 20 and two filtering parts 30, the air inlet vent 12 can be filtered and the air outlet vent 12 can be avoided while switching the air inlet and outlet.

[0057] In this embodiment, the first air outlet is arranged at the upper part of the housing 10, and the second air outlet is arranged at the lower part of the housing 10, and the first air outlet and the second air outlet are arranged alternately in the horizontal direction. Through the above arrangement, it is possible to achieve upper air intake and lower air outlet, or lower air intake and upper air outlet, thereby improving flexibility. Specifically, the first air outlet faces directly upward, and the second air outlet faces directly downward.

[0058] In this embodiment, one end of the shielding part 20 is rotatably arranged on an edge of the air outlet 12, and a limiting member 16 is arranged on the other edge of the air outlet 12. The limiting member 16 is located on the rotation path of the other end of the shielding part 20. When the shielding part 20 rotates to the blocking position, the limiting member 16 cooperates with the other end stopper of the shielding part 20. In this way, the rotation angle of the shielding part 20 can be limited by the limiting member 16, so that the shielding part 20 moves to an accurate position. On the one hand, this can prevent the shielding part 20 from moving to the outside of the housing 10 to affect the appearance, and on the other hand, it can improve the performance of blocking the air outlet 12 and prevent dust from entering. The limiting member 16 can be set as a long strip structure.

[0059] Another embodiment of the present invention also provides an air conditioner, which includes the air inlet and outlet structure provided above. Applying the technical solution of this embodiment, a shell 10 and a shielding part 20 are provided in the air inlet and outlet structure, the shell 10 has an air duct 11 and an air outlet 12 connected to the air duct 11, and the shielding part 20 is movably provided on the shell 10, and the shielding part 20 has a blocking position for blocking the air outlet 12 and a avoiding position for avoiding the air outlet 12, wherein the blocking position is located at the air outlet 12, and the avoiding position is located in the cavity of the shell 10. When the shielding part 20 is in the blocking position, the air outlet 12 is closed, and when the shielding part 20 is in the avoiding position, the air outlet 12 is opened. Through the above arrangement, the air outlet 12 can be opened when the shielding part 20 moves to the inside of the cavity of the shell 10, so that air can enter or exit through the air outlet 12. Since the shielding part 20 is located inside the shell 10 when the air outlet 12 is opened, and does not extend outside the shell 10, it does not affect the aesthetics of the air conditioner. The shielding part 20 is used to replace the existing air guide plate, so as to avoid the problem that the extended air guide plate affects the aesthetics of the air conditioner. In this embodiment, the air conditioner further includes a fan 60, which is arranged in the housing 10. The fan 60 can be arranged in the air duct 11 to increase the power of the air flow. The air conditioner can be set as a wall-mounted air conditioner.

[0060] The shielding part and the filter part provided by the present invention adopt an integrated assembly structure, and the upper and lower air outlets can switch the air inlet and outlet through a gear mechanism. In the off state, the filter screen and the baffle are closed to ensure a beautiful appearance; when the air is entering, the baffle is opened for avoidance, and the filter screen is opened for filtering, ensuring smooth air intake and the function of filtering dust; when the air is discharged, the baffle and the filter screen form the side wall of the air duct, ensuring the air volume and reducing noise. Due to the use of the integrated assembly structure of the present invention, the parts of the upper and lower air outlets are reduced, the production efficiency is improved, the appearance is guaranteed, and the dust filtering effect is not lost, which is better for consumers to use.

[0061] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
