When a user uses the air conditioner, if a person is close to the air outlet of the air conditioner, wind directly blows to the person to cause discomfort of the person easily, and when the person is far away from the air outlet of the air conditioner, the air conditioner is required to supply air in a long distance, and how to realize close-distance direct blowing prevention and long-distance air supply is a problem to be solved at present. In view of the foregoing, the present utility model has been made to provide an indoor unit of an air conditioner that overcomes or at least partially solves the foregoing problems, and is capable of achieving close-range direct blowing prevention and long-range air blowing, so as to better satisfy user demands.

Fig. 1 is a schematic structural view of an indoor unit of an air conditioner according to an embodiment of the present utility model, as shown in fig. 1, and referring to fig. 2 to 5, an indoor unit 1 of an air conditioner is provided, which includes a casing 10 and an air outlet provided at a front surface of the casing 10, and further includes two wind shielding devices 12, the two wind shielding devices 12 being sequentially provided at the air outlet in a lateral direction. Both windshields 12 are movably arranged such that each windshield 12 has a first position directly in front of the air outlet.

Specifically, the air outlet is preferably disposed at an upper portion of the front surface of the casing 10, and of course, the air outlet may be disposed at a middle portion or a lower portion of the front surface of the casing 10. The air outlet is preferably rectangular in shape, and the length of the air outlet is greater than the width of the air outlet. Of course, the shape of the air outlet may be square, circular, oval, polygonal or other shapes, as well, which are not described herein.

As shown in fig. 3, when both windshields 12 are in the first position, both windshields 12 are directly in front of the air outlet. When the air conditioner indoor unit 1 sends air, air flows out from the air outlet, at least part of the air flows cannot flow along the right front under the blocking of the two wind shields 12, and flows out to the left side and the right side of the two wind shields 12 respectively, so that the air conditioner indoor unit 1 presents an air outlet state that the front air is not blown out or is less blown out, and meanwhile, the air outlet state of the two air outlets is realized, and the anti-direct blowing function of the air conditioner indoor unit 1 is realized. This arrangement makes it possible to prevent excessive air flow from blowing through the user when the user is in front of the air outlet. When the user is at a position far away from the indoor unit of the air conditioner, the user can be taken care of by the air flows blown out from the two sides. The arrangement can realize close-range direct blowing prevention and long-distance air supply, and better meets the demands of users.

In some embodiments of the present utility model, as shown in FIG. 3, the wind deflector 12 is a wind deflector 122. Specifically, the shape of the wind deflector 122 is adapted to the shape of the air outlet, that is, if the shape of the air outlet is rectangular, the shape of the wind deflector 122 is also rectangular. Of course, in some alternative embodiments of the present utility model, the wind shielding device may also be an air outlet body with a certain thickness.

Further, in some embodiments of the utility model, each wind deflector 122 has a vertical edge that is proximate to the other wind deflector 122, the vertical edges of the two wind deflectors 122 meeting when both wind deflectors 122 are in the first position. Specifically, after the two wind shields 122 are moved to the first position, the vertical edges of the two wind shields 122 are connected, so that a gap between the two wind shields 122 that can be ventilated is avoided, and the air flow flowing out from the air outlet completely flows out from both sides of the wind shields 122 to the outside, so that the anti-direct blowing effect of the air conditioner indoor unit 1 is better.

In some embodiments of the utility model, as shown in fig. 4, the two windshields 12 also have second positions on opposite lateral sides of the air outlet. Specifically, one of the windshields 12 is located laterally to the left of the air outlet when it is in the second position. Wherein the other windscreen 12 is located laterally to the right of the air outlet when in the second position. When the two wind shields 12 are both positioned at the second position, the air outlet is not blocked right in front of the air outlet, and when the air conditioner indoor unit 1 sends air, air flows out from the air outlet and can flow along the right front, so that the air conditioner indoor unit 1 presents an air outlet state for forward air supply, and the direct blowing function of the air conditioner indoor unit 1 is realized. The air conditioner indoor unit has multiple air outlet modes, and is beneficial to meeting multiple requirements of users.

When the air conditioning indoor unit 1 is not required to prevent direct blowing, the two wind shields 12 are moved from the first position to the second position, that is, the two wind shields 12 are respectively moved to the left side and the right side of the air outlet from the right front of the air outlet, so that the air conditioning indoor unit 1 is directly blown. When the air conditioner indoor unit 1 needs to prevent direct blowing, the two wind shields 12 are moved from the second position to the first position, that is, the two wind shields 12 are respectively moved from the left side and the right side of the air outlet to the right front of the air outlet, so that the air conditioner indoor unit 1 can prevent direct blowing. Since the second position is adjacent to the first position, the time required for switching the two wind shielding devices 12 between the first position and the second position is shortened, and the speed of switching the air conditioning indoor unit 1 between direct blowing and direct blowing prevention is increased.

As shown in fig. 1, in some embodiments of the present utility model, the front surface of the casing 10 is provided with two mounting openings 14 for accommodating the wind shielding devices 12, and the two mounting openings 14 are respectively located at two lateral sides of the air outlet, so that the two wind shielding devices 12 are respectively located in the two mounting openings 14 when in the second position.

Specifically, the shape of the mounting opening 14 is adapted to the shape of the wind shielding device 12. For example, when the wind shielding device 12 is elongated, the mounting opening 14 is also elongated, and when the wind shielding device 12 is circular, the mounting opening 14 is also circular. When the two windshields 12 move from the first position to the second position, the two windshields 12 are respectively positioned in the two mounting openings 14, so that the surfaces of the two windshields 12 are flush with the front surface of the casing 10, and the whole indoor unit 1 of the air conditioner is more attractive and tidy.

Specifically, the slide bar 121 is provided in plurality. The slide bar 121 is disposed obliquely with respect to the wind shielding device 12, and the front end of the slide bar 121 is closer to the air outlet than the rear end. In this way, when the sliding bar 121 moves forward along the length direction thereof, the front end moves along the oblique front direction, and then drives the wind shielding device 12 to move along the oblique front direction, so that the wind shielding device 12 moves from the lateral side of the air outlet to the position right in front of the air outlet, and the switching between the second position and the first position of the wind shielding device 12 is realized. When the sliding bar 121 moves obliquely backward along the length direction, the wind shielding device 12 is driven to move obliquely backward far away from the air outlet, so that the wind shielding device 12 moves to one side of the air outlet transversely from the right front of the air outlet, and the switching of the wind shielding device 12 from the first position to the second position is realized.

The ratio between the width of the air outlet and the width of the two wind deflectors 122 when they meet at the vertical edges is 0.8 to 1.2. Preferably, the distance between the wind deflector 122 and the vertical plane in which the air outlet is located is 8cm. The ratio between the width of the air outlet and the width of the two wind deflectors 122 when they meet at the vertical edge is 1.
