The face frame 120 and the panel 110 are disposed at the front side of the case 100, wherein the face frame 120 is disposed at the inner side of the case 100 with respect to the panel 110. In addition, in the present embodiment, in order to increase the space used inside the indoor unit 10 of the air conditioner, the panel 110 is of a planar design, and specifically, the panel 110 may be of an approximately flat and thin plate design.
In this embodiment, a rotation mechanism 200 is further provided, and the rotation mechanism 200 drives the panel 110 to rotate relative to the face frame 120, so that the panel 110 has a first state and a second state. It can be understood that, the face frame 120 is stationary with respect to the housing 100, the rotating mechanism 200 drives the panel 110 to rotate relatively, the first state refers to an initial position of the panel 110, and the second state refers to a position of the panel 110 after the panel 110 rotates with respect to the face frame 120.
Further, the rotation mechanism 200 includes a motor 210, a first link 220, and a second link 230; the motor 210 is mounted on the face frame 120.

Preferably, the motor 210 is a stepper motor 210. The following description will take an example in which one end of the first link 220 is connected to the motor 210 and one end of the second link 220 rotates the connecting frame 120.
Furthermore, one end of the first link 220 is rotatably connected to the face frame 120, and the rotatable connection means that the first link 220 and the face frame 120 can rotate relatively, and the other end of the first link 220 and the other end of the second link 230 are both rotatably connected to the panel 110; the two rotational connections mean that the first link 220, the second link 230 and the panel 110 can rotate relatively. In the present invention, the panel frame 120 is fixedly mounted on the housing 100, and it is understood that the first link 220 is rotatable relative to the panel frame 120. Similarly, one end of the second connecting rod 230 is rotatably connected to the face frame 120, and the rotational connection therein is analyzed in the same way, which is not described herein again.
When the panel 110 is in the first state, the panel 110 is attached to the face frame 120. When the panel 110 is in the second state, the panel 110 is inclined downward, and the distance from the connection point of the first link 220 and the panel 110 to the face frame 120 is greater than the distance from the connection point of the second link 230 and the panel 110 to the face frame 120, that is, in the second state, the panel 110 and the face frame 120 form an upward angle.
According to the technical scheme of the utility model, the rotating mechanism 200 formed by combining the motor 210, the first connecting rod 220 and the second connecting rod 230 is adopted, and the rotating mechanism 200 is used for driving the panel 110 to rotate relative to the face frame 120, so that the panel 110 has a first state and a second state. Compared with a gear rack transmission mechanism, the rotating mechanism 200 provided by the utility model can reduce the sound generated when the panel 110 is opened or closed, and the rotating mechanism 200 is simple, low in cost, high in production efficiency and high in reliability. Meanwhile, the rotating mechanism 200 is installed on the face frame 120, and occupies a small space.
Referring to fig. 1 to fig. 3, in an embodiment, an air inlet 121 and an air outlet 122 are formed on the face frame 120, and the air inlet 121 is located above the air outlet 122; in the first state, the panel 110 closes both the air inlet 121 and the air outlet 122; in the second state, the panel 110 opens both the intake opening 121 and the exhaust opening 122.
It should be noted that, regarding the performance of the air conditioner indoor unit itself, when the air conditioner indoor unit 10 is in a standby state, the air inlet 121 or the air outlet 122 does not need to be closed. In view of this, in many air conditioner indoor units in the related art, the air inlet 121 or the air outlet 122 is not provided with a damper, or the air inlet 121 or the air outlet 122 is independently controlled by a damper. In addition, the air conditioner indoor unit 10 is usually that the air inlet 121 and the air outlet 122 are opened simultaneously or closed simultaneously, based on the condition that a damper is provided, in this embodiment, the air inlet 121 and the air outlet 122 are both disposed on the panel frame 120, and the panel frame 120 and the panel 110 are correspondingly disposed, so that when the air conditioner indoor unit 10 is in a standby state, that is, when the panel 110 is in the first state, the panel 110 closes both the air inlet 121 and the air outlet 122, thereby preventing external dust from entering the air conditioner indoor unit 10. When the air conditioner indoor unit 10 is in the working state, that is, the panel 110 is in the second state, the panel 110 opens both the air inlet 121 and the air outlet 122, and the air conditioner indoor unit 10 is working. Therefore, the opening or closing of the air inlet 121 and the air outlet 122 is controlled by one panel 110, so that the structure of the air conditioner indoor unit is simplified, and the performance of the air conditioner indoor unit 10 is improved.
Specifically, the air conditioner indoor unit 10 provided by the present invention may be a general air conditioner indoor unit 10, or may be an embedded air conditioner indoor unit 10, or an air conditioner indoor unit 10 for other purposes. One of the usage scenarios of the embedded air conditioner indoor unit 10 is an embedded wardrobe. In the use scene of embedding the wardrobe, the heating function of applying the air conditioner can be heating sterilization of the wardrobe or drying of clothes of the wardrobe, and the moisture prevention of the wardrobe can also be realized.
Referring to fig. 7, 8 and 13, in an embodiment, when the panel 110 is switched from the first state to the second state, the first link 220 rotates by an angle α, and the second link 230 rotates by an angle β. At the same time, the lowest point of the panel 110 moves from point H to point H1, and α ═ β or | α - β | ≦ 3 ° is required in order to make the motion trajectory of the panel 110 approach a straight line as much as possible from point H to point H1.
It should be noted that the smaller the | α - β | is, the more the motion trajectory of the panel 110 approaches the straight line motion from point H to point H1. Therefore, when the rotation speed of the motor 210 is constant while the panel 110 is switched from the first state to the second state, the difference between α and β increases as the difference between the length of the first link 220 and the length of the second link 230 increases. The embodiment requires that α ═ β or | ≦ 3 °, which means that the lengths of the first link 220 and the second link 230 cannot be different too much. As to the specific size of α - β |, for example but not limited to: 0 °, 1 °, 2 °, 3 °, 1.5 °, 2.5 °, etc. Further, when the panel 110 is switched from the first state to the second state, the motion trajectory of the panel 110 from H to H1 is as close as possible to a linear motion, where the approximate linear motion means that the distance between the bottom end of the panel 110 and the face frame 120 is less than 6mm, and specifically, the distance includes, but is not limited to, 1mm, 2mm, 3mm, 4mm, 5mm, and so on.
Referring to fig. 5, 6 and 13, in a preferred embodiment, in order to ensure the intake volume of the intake opening 121, in the second state, the included angle between the panel 110 and the face frame 120 is θ, and θ ranges from 15 ° to 45 °, specifically, the value of θ includes, but is not limited to, 15 °, 18 °, 20 °, 22 °, 25 °, 28 °, 30 °, 32 °, 35 °, 28 °, 40 °, 42 °, and 45 °. In addition, in order to enable the panel 110 to be opened at a desired angle, a vertical distance L1 between the first link 220 and the face frame 120 is smaller than a vertical distance L2 between the second link 230 and the face frame 120 in the first state. It should be noted that, after the product selects the value of θ according to the required air intake, the specific values of L1 and L2 can be flexibly designed according to the opening and closing angle and the whole space of the air conditioner.
Referring to fig. 4, 7 and 12, in a preferred embodiment, the rotating mechanism 200, the panel 110 and the frame 120 form a mechanism, which is a typical four-bar mechanism in terms of mechanical dimension, and the mechanism may generate a motion dead point during the motion, and the motion dead point may cause a jamming phenomenon of the rotating mechanism 200. Therefore, in this embodiment, the face frame 120 is further provided with a limiting groove 123, and the first link 220 and the second link 230 penetrate through the limiting groove 123 to be rotatably connected with the panel 110. At this time, the motor 210 is installed on a side of the face frame 120 away from the panel 110, and a place where the first link 220 or the second link 230 is rotatably connected to the panel 110 is also located on a side where the motor 210 is located.
Referring to fig. 6, 10 and 12, based on the above embodiment, the first link 220 is bent to adapt to other structures of the indoor unit of the air conditioner and to ensure that the panel 110 is opened at a sufficient angle. Specifically, the first link 220 is in a bending design, that is, the first link 220 is not a straight rod, and may be in a bending design or an arc bending, and the like, and the detailed bending amplitude and the bending position need to be adjusted according to specific situations, which is not limited herein.
In an embodiment, in order to further improve the stability of the panel rotation, two sets of the rotation mechanisms are respectively arranged at two ends of the face frame in the length direction. Of course, the number of the rotating mechanisms can be one set, three sets or more than three sets, and when one set of rotating mechanism is used, the rotating mechanism is usually arranged in the middle part so as to ensure the stability of the whole panel in the moving process. The three sets of rotating mechanisms can be set at each of two ends and the middle part of the surface frame in the length direction, and are suitable for the condition that the surface frame of the indoor unit of the air conditioner is longer. In summary, based on the length of the indoor unit of a general air conditioner, the cost performance of the two sets of rotating mechanisms is highest in comprehensive consideration of space utilization, cost, structure and the like.
The present invention further provides an air conditioner, which includes the above air conditioner indoor unit, and the specific structure of the air conditioner indoor unit refers to the above embodiments, and since the air conditioner employs all technical solutions of all the above embodiments, the air conditioner at least has all beneficial effects brought by the technical solutions of the above embodiments, and details are not repeated herein.
