In the description of the present invention, "the first feature" and "the second feature" may include one or more of the features. Furthermore, the terms "first", "second" and "first" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the present invention, the first feature being "on" or "under" the second feature may include the first and second features being in direct contact, and may also include the first and second features being in contact with each other not directly but through another feature therebetween. In the description of the invention, "above", "over" and "above" a first feature in a second feature includes the first feature being directly above and obliquely above the second feature, or simply means that the first feature is higher in level than the second feature.

The first outlet 111 extends along a second direction to form a curved structure, wherein the first direction is perpendicular to the second direction, that is, the first outlet 111 extends along the second direction (for example, the left and right direction in the figure) to form a curved shape, in other words, in a horizontal plane, a projection of the first outlet 111 is a curve extending along the second direction. For example, referring to fig. 1, the first outlet port 111 extends in an arc shape along the second direction. Therefore, the air supply area of the first air outlet 111 in the second direction is increased, and the air supply range is expanded, so that the uniformity of the indoor temperature is improved, and the running comfort of the indoor unit 100 of the air conditioner is improved.

In the description of the present invention, "a plurality" means two or more.

Specifically, for example, referring to fig. 1, since the switch door is located at the first air outlet 111, the first air flow blown out from the first air outlet 111 can be guided, and since the switch door can rotate relative to the casing 1, the air outlet direction of the first air outlet 111 can be changed by controlling the rotation of the switch door 2, and then the flow direction of the first air flow can be changed, so that the air blowing form of the indoor unit 100 of the air conditioner is variable, the comfort of the operation of the air conditioner can be improved, and the use experience of a user is improved.

According to the utility model discloses indoor unit of air conditioner 100, through setting up first air outlet 111 and second air outlet 112, can increase the air-out area, and first air outlet 111 extends to the curved surface structure along the second direction, be favorable to increasing first air outlet 111 the ascending air supply area of second side, and then enlarge the scope of blowing, the rotation through control switch door 2 can change the air-out direction of first air outlet 111 in addition, make indoor unit of air conditioner 100's the form of blowing changeable, can improve the travelling comfort of air conditioner operation.

In some embodiments of the present invention, as shown in fig. 4 and 5, the indoor unit 100 of the air conditioner further includes a first switching door set 2, a second switching door set 3, a first driving assembly 4, and a second driving assembly 5.

From this, when a plurality of first switch door 21 of first switch door group 2 are in the closed condition, first switch door group 2 can play the effect of sheltering from partial first air outlet 111, when a plurality of first switch door 21 of first switch door group 2 are in the open condition, a plurality of first switch door 21 can play the guide effect to the partial first air current of flowing through it, particularly, because first switch door 21 is rotatable relative casing 1, consequently the open and shut angle of accessible adjustment first switch door 21, the flow direction of adjustment air current, thereby realize adjusting the air supply direction of air conditioning indoor set 100.

In addition, through setting up first connecting rod 22, first connecting rod 22 links to each other with every first switch door 21, first connecting rod 22 can play the transmission here, through the transmission of first connecting rod 22 alright drive a plurality of first switch doors 21 simultaneous movement, thereby reducible drive assembly's quantity, reduce driving cost, and because first connecting rod 21 drives a plurality of first switch doors 21 simultaneous movement, thereby make a plurality of first switch doors 21 have the same rotation amplitude and angle, the part first air current of first switch door group 2 of flowing through just has the same flow direction like this, thereby can not lead to the fact collision each other between the air current because of the difference of flow direction, the kinetic energy loss of this part first air current has been reduced, improve the air supply effect.

It should be noted that the first driving assembly 4 is only used for providing the main power for the rotation of the first switching door group 2, and specifically, the first driving assembly is connected to the first switching door 21 or the first connecting rod 22 in the first switching door group 2, and the like, which is not particularly limited, and can be selectively arranged according to actual requirements and specific situations. For example, the first driving assembly 4 may be connected to one of the first switching doors 21 of the first switching door group 2, and each of the first switching doors 21 is connected to the first connecting rod 22, so that when one of the first switching doors 21 is driven to rotate by the first driving assembly 4, the other first switching doors 21 may be driven to rotate synchronously through the transmission function of the first connecting rod 22, thereby adjusting the opening and closing angle of the first switching door group 2; or, the first driving assembly 4 can be connected to the first connecting rod 22 of the first switch door group 2, and can drive the first connecting rod 22 to slide, and since each first switch door 21 is connected to the first connecting rod 22, the first connecting rod 22 can drive the plurality of first switch doors 21 to rotate synchronously when sliding, so as to adjust the opening and closing angle of the first switch door group 2.

Optionally, the first driving assembly 4 is a first driving motor 41, and the first driving motor 41 is configured to drive the plurality of first switching doors 21 to rotate synchronously. Therefore, the structure is simple and the cost is low.

In the present invention, unless otherwise expressly stated or limited, the terms "mounted," "connected," "secured," and the like are to be construed broadly and can, for example, be fixedly connected, detachably connected, or integrally formed; either directly or indirectly through intervening media, either internally or in any other relationship. The specific meanings of the above terms in the present invention can be understood by those skilled in the art according to specific situations.

As shown in fig. 4 and 5, the second switching door group 3 is located at the first air outlet 111 and includes a plurality of second switching doors 31, each second switching door 31 is rotatable relative to the housing 1, a rotation center line of the second switching door 31 is parallel to a rotation center line of the first switching door 21, the plurality of second switching doors 31 move synchronously, the second driving assembly 5 is configured to drive the second switching door group 3 to move, and the second driving assembly 5 can provide a main driving force for the second switching door group 3 to rotate.

Therefore, when the second switching doors 31 of the second switching door group 3 are in the closed state, the second switching door group 3 can shield the rest of the first air outlet 111, and when the second switching doors 31 of the second switching door group 3 are in the open state, the second switching doors 31 can guide part of the first air flow flowing through the second switching doors, specifically, since the second switching doors 31 can rotate relative to the casing 1, the opening and closing angle of the second switching doors 31 can be adjusted, the flow direction of the air flow can be adjusted, and thus the air supply direction of the air-conditioning indoor unit 100 can be adjusted. Moreover, the synchronous movement of the second switching doors 31 means that the second switching doors 31 have the same rotation amplitude and angle, so that the partial first airflows flowing through the second switching door group 3 have the same flow direction, and the airflows do not collide with each other due to different flow directions, thereby reducing the kinetic energy loss of the partial first airflows and improving the air supply effect.

It can be understood that, since the first switching door group 2 and the second switching door group 3 are independent of each other, the rotation of the first switching door 21 and the rotation of the second switching door 31 do not affect each other, so that the first airflow can have more blowing forms when being blown out from the first air outlet 111, and more requirements of users can be met; because the rotation center line of the second switch door 31 is parallel to the rotation center line of the first switch door 21, there may be a situation that the rotation angles of the first switch door 21 and the second switch door 31 are opposite, in this situation, for example, in the direction blowing from the first air outlet 111 to the indoor along the first air flow, the first switch door group 2 and the second switch door group 3 may form an outward-expanding flow path at the first air outlet 111, so that the first air flow flowing through the first air outlet 111 may be blown to the indoor in a diffusion state, the air supply range is increased, the indoor temperature may be rapidly and uniformly distributed, and the comfort experience of the user is improved.

The first opening/closing door 21 and the second opening/closing door 31 are rotatable to close the first outlet 111, and the plurality of first opening/closing doors 21 and the plurality of second opening/closing doors 31 constitute the plurality of opening/closing doors. For example, when the air conditioning indoor unit 100 is turned off or when air does not need to be blown out from the first outlet 111, the first opening/closing door 21 and the second opening/closing door 31 may be rotated to a state where the first outlet 111 is closed. In this way, it is beneficial to prevent dust and the like from entering the casing 1 through the first air outlet 111, and to increase the air volume output of the second air outlet 112 when the indoor unit 100 of the air conditioner is in the working state.

Optionally, the plurality of first switching doors 21 and the plurality of second switching doors 31 are arranged along the curved surface structure of the first air outlet 111 in the second direction, that is, referring to fig. 5, the rotation center line of the plurality of first switching doors 21 and the rotation center line of the plurality of second switching doors 31 form a vertical arc-shaped surface, and the arc-shaped surface matches with the curved surface shape of the first air outlet 111, so that a better closing effect can be obtained when the first switching doors 21 and the second switching doors 31 close the first air outlet 111.

In some embodiments of the present invention, in the plane perpendicular to the rotation center line of the first switch door 21, the distance between the rotation center line of the first switch door 21 and the two ends of the first switch door 21 is not equal.

Specifically, for example, referring to fig. 5, a first rotating shaft 211 is disposed on the first switch door 21, a rotation center line of the first switch door 21 is an axis of the first rotating shaft 211, the first rotating shaft 211 is vertically disposed, the first switch door 21 has a first outer end 21a and another end opposite to the first outer end 21a, that is, a first inner end 21b, wherein when the first switch door 21 is in a state of opening the first air outlet 111, one end of the first switch door 21 away from the inside of the housing 1 is the first outer end 21a, and the first connecting rod 22 is connected to the first inner end 21b of the first switch door 21. In a plane perpendicular to the rotation center line of the first opening/closing door 21, for example, in a horizontal plane, the distance between the rotation center line of the first opening/closing door 21 and the two ends of the first opening/closing door 21 is not equal, that is, the distance between the axis of the first rotating shaft 211 and the first outer end 21a and the first inner end 21b of the first opening/closing door 21 is not equal. This includes two cases, the first case is that the distance from the axis of the first rotating shaft 211 of the first opening and closing door 21 to the first outer end 21a is larger than the distance to the first inner end 21b, that is, the first rotating shaft 211 is closer to the first inner end 21b, in this case, the first outer end 21a of the first opening and closing door 21 can have a larger rotating amplitude, and thus, a better guiding effect for the first air flow can be obtained; the second condition is that the distance from the axis of the first rotating shaft 211 of the first opening/closing door 21 to the first outer end 21a is smaller than the distance from the first inner end 21b, that is, the first rotating shaft 211 is closer to the first outer end 21a, in this case, most of the area of the first opening/closing door 21 is located inside the housing 1 when the first opening/closing door 21 rotates, which can provide better protection for the first opening/closing door 21.

In some embodiments of the present invention, in the plane perpendicular to the rotation center line of the second switch door 31, the distance between the rotation center line of the second switch door 31 and the two ends of the second switch door 31 is not equal.

Specifically, for example, referring to fig. 5, a second rotating shaft 311 is disposed on the second switch door 31, a rotating center line of the second switch door 31 is an axis of the second rotating shaft 311, the second rotating shaft 311 is vertically disposed, the second switch door 31 has a second outer end 31a and another end opposite to the second outer end 31a, that is, a second inner end 31b, wherein when the second switch door 31 is in a state of opening the first air outlet 111, one end of the second switch door 31 away from the inside of the housing 1 is the second outer end 31a, and the second connecting rod 32 is connected to the second inner end 31b of the second switch door 31.

In a plane perpendicular to the rotation center line of the second opening/closing door 31, for example, in a horizontal plane, the distance between the rotation center line of the second opening/closing door 31 and the two ends of the second opening/closing door 31 is not equal, that is, the distance between the axis of the second rotating shaft 311 and the second outer end 31a and the second inner end 31b of the second opening/closing door 31 is not equal. This includes two cases, the first case is that the distance from the axis of the second rotating shaft 311 of the second opening/closing door 31 to the second outer end 31a is greater than the distance to the second inner end 31b, i.e. the second rotating shaft 311 is closer to the second inner end 31b, in this case, the second outer end 31a of the second opening/closing door 31 can have a larger rotating amplitude, and thus can have a better guiding effect on the first air flow; in the second case, the distance from the axis of the first rotating shaft 211 of the second switching door 31 to the second outer end 31a is smaller than the distance from the axis of the second rotating shaft 211 to the second inner end 31b, that is, the second rotating shaft 311 is closer to the second outer end 31a, in this case, most of the area of the second switching door 31 is located inside the housing 1 when the second switching door 31 rotates, which can provide better protection for the second switching door 31.

In some embodiments of the present invention, the number of the first switch doors 21 and the number of the second switch doors 31 are equal. Referring to fig. 4, in the present embodiment, the first switching door 21 and the second switching door 31 are both two. Alternatively, the first and

second switching doors

In some embodiments of the present invention, the second driving assembly 5 is a second driving motor 51, and thus, has a simple structure.

It should be noted that, in addition to the structural form that the second driving motor 51 is matched with the second connecting rod 32, the manner for realizing the synchronous rotation of the second opening/closing door 31 may also be only the second driving motor 51, for example, the second driving assembly 5 may include a plurality of second driving motors 51, and the plurality of second driving motors 51 correspond to the plurality of second opening/closing doors 31 one by one, so that each second driving motor 51 may drive the corresponding second opening/closing door 31 to rotate, and the synchronous rotation of the plurality of second opening/closing doors 31 may be realized by controlling the state of each second driving motor 51.

In some optional embodiments of the present invention, the first driving motor 41 and/or the second driving motor 51 are detachably mounted on the housing 1, for example, by screws or fasteners. Therefore, the connection mode is simple and reliable.

As some embodiments of the present invention, since the space inside the air conditioning indoor unit 100 is generally narrow and small, and the power for driving the first opening/closing door 21 and/or the second opening/closing door 31 to rotate in this embodiment does not need to be too large, the structure of the device is more compact in order to save the installation space, and the production cost of the device is reduced, and the first driving motor 41 and/or the second driving motor 51 may adopt a micro motor. Of course, the driving mode of the first opening/closing door 21 and/or the second opening/closing door 31 is not limited to motor driving, and in other alternative embodiments of the present invention, other driving modes such as hydraulic driving or pneumatic driving may be adopted to realize the rotation of the first opening/closing door 21 and/or the second opening/closing door 31, and which driving mode is adopted may be selected according to the actual installation space and the production cost of the indoor unit 100 of the air conditioner.

In some optional embodiments of the present invention, the rotation center line of the first opening/closing door 21 and the rotation center line of the second opening/closing door 31 may be in a horizontal state in addition to the vertical state as shown in fig. 5. Specifically, for example, the first opening/closing door 21 and the second opening/closing door 31 are rotated independently of each other, the rotation center line of the first opening/closing door 21 is horizontally arranged so that the first opening/closing door 21 can be rotated up and down with respect to the housing 1, and the rotation center line of the second opening/closing door 31 is horizontally arranged so that the second opening/closing door 31 can be rotated up and down with respect to the housing 1; in this case, when the first opening/closing door 21 and the second opening/closing door 31 are both rotated upward, the first air flow is blown obliquely upward from the first outlet 111 toward the room, so that a greater blowing distance can be provided.
