Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the accompanying drawings are illustrative only for the purpose of explaining the present invention, and are not to be construed as limiting the present invention.

An air outlet part of an air-conditioning indoor unit 100 according to an embodiment of the present invention will be described with reference to the accompanying drawings. The air outlet component can be used for a wall-mounted air conditioner indoor unit and can also be used for a vertical air conditioner indoor unit. Specifically, the air outlet component can guide the air outlet flow of the indoor unit 100 of the air conditioner, so that the air outlet direction and the air outlet range of the indoor unit 100 of the air conditioner can be adjusted through the air outlet component, and the air supply requirement of a user is met.

As shown in fig. 1, the air outlet part of the indoor unit 100 of the air conditioner according to the embodiment of the present invention includes an air outlet frame 2 and a louver 1.

An air outlet 21 is formed on the air outlet frame 2. A plurality of louvers 1 are provided on the air-out frame 2 so as to be capable of swinging left and right. When the air-conditioning indoor unit 100 works, the left-right air outlet airflow distribution can be adjusted by adjusting the left-right swing angle of the louver 1.

It should be noted that, when the human body stands parallel to and facing the indoor unit 100 of the air conditioner, the direction of the left hand side of the human body may be understood as the "left" direction of the present application, and correspondingly, the direction of the right hand side of the human body may be understood as the "right" direction of the present application. The direction of the indoor air conditioner 100 approaching the human body is "front" in the present application, and the direction of the indoor air conditioner 100 facing away from the human body is "rear" in the present application.

In addition, in the description of the present invention, it is to be understood that the terms "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", and the like indicate orientations or positional relationships based on those shown in the drawings, and are only for convenience of description and simplicity of description, but do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and thus, are not to be construed as limiting the present invention.

Specifically, the louver 1 includes a plurality of sub-blades 11. In the description of the present invention, the term "plurality" means two or more. For example, the louvers 1 may be two, three, four, etc. Each louver 1 may comprise two, three, four, etc. sub-vanes 11. The number of the sub-blades 11 can be adjusted according to the specification of the louver 1, and the utility model is not limited thereto.

The plurality of sub-blades 11 are connected in sequence, and two adjacent sub-blades 11 can rotate relatively. For example, the plurality of sub-blades 11 may be connected in series in the outlet air flow direction (e.g., the front-rear direction in fig. 1) of the air conditioning indoor unit 100. In an initial state (for example, when the air conditioning indoor unit 100 is not operated or the air conditioning indoor unit 100 is just started), the extending direction of each sub-vane 11 may be substantially parallel to the air outlet direction of the air conditioning indoor unit 100.

The connecting rods may be connected to a plurality of louvers 1. In particular, each louver 1 is associated with a connecting rod. Therefore, when the driving mechanism drives the connecting rod to move, the connecting rod can drive the plurality of shutters 1 to move synchronously, and linkage among the plurality of shutters 1 is realized. Simple structure and convenient control.

In particular, in some embodiments of the utility model, the connecting rod may be connected to one of the sub-blades 11 of the shutter 1. When the driving mechanism drives the connecting rod to move, the sub-blades 11 connected with the connecting rod swing left and right under the driving of the connecting rod, and because the two adjacent sub-blades 11 can rotate relatively, when one sub-blade 11 swings, the sub-blade 11 can drive the sub-blade 11 adjacent to the sub-blade 11 to swing, so that the swing of each sub-blade 11 can be realized, and an included angle is formed between the two adjacent sub-blades 11. It should be noted that the "included angle" in this application refers to the smallest positive angle formed by two straight lines intersecting.

Like this, every sub-blade 11 all can swing an angle, utilize a plurality of angle stacks, realize the target swing angle, thereby can replace traditional single angle of attack through the multiunit angle of attack, make single big angle of attack decompose into a plurality of little angle of attack, can reduce the angle of attack of air current, make near tripe 1 air current can laminate with tripe 1, improve the smooth and easy nature that the air current flows, reduce the risk that air current and tripe 1 break away from, thereby improved the vortex problem that causes because of air current and tripe 1 separation, the air-out stability has been improved, the air-out noise has been reduced, surge etc. has been avoided appearing effectively. Meanwhile, the temperature difference caused by the vortex area on the two sides of the louver 1 can be reduced, and the generation of condensation is reduced. In addition, the pressure loss caused by the fact that the front of the incoming flow impacts the louver 1 can be reduced, and the flow of the outlet air flow is increased.

Further, when the conventional louver 1a swings, the occupied space is larger than that of the multi-section louver 1, and the conventional louver 1a swings for a longer time, so that the left and right wind swinging angles are limited, and the multi-section louver 1 can decompose a single wind swinging angle into a plurality of small wind swinging angles to realize a larger wind swinging angle. That is to say, the multi-section louver 1 occupies a small space, and can realize a wider range of wind sweeping, so that the user experience is better.

For example, in some embodiments of the present invention, referring to fig. 2 and 3, the louver 1 includes two sub-blades 11, for convenience of description, the sub-blade 11 near the air inlet side is referred to as a "first sub-blade", the sub-blade 11 near the air outlet side is referred to as a "second sub-blade", when the louver 1 swings, the first sub-blade and the second sub-blade both swing a certain angle, and an included angle is formed between the first sub-blade and the second sub-blade. At this time, the sum of the included angle between the normal of the plane where the first sub-blade and the air outlet 21 are located and the included angle formed between the first sub-blade and the second sub-blade is the included angle between the louver 1 and the incoming airflow.

As shown in fig. 3, when the angle between the louver 1 and the incoming airflow is 60 °, the angle between the first sub-blade and the normal of the plane where the air outlet 21 is located may be 24 °, and the angle between the second sub-blade and the first sub-blade may be 36 °. That is, the angle between the first sub-blade and the incoming airflow may be 24 °, and the angle between the second sub-blade and the incoming airflow may be 36 °. Therefore, included angles between the first sub-blade and the second sub-blade and incoming airflow are smaller than 60 degrees, the probability that the back of the tail end of the louver 1 is separated from the airflow is greatly reduced, the airflow stability of the louver 1 during left-right air swinging is improved, the air outlet airflow flow is increased, and the air outlet noise is reduced.

Referring to fig. 4a and 4b, when the swing angle of the conventional louver 1a is 0 ° and 30 °, the airflow near the conventional louver 1a is better attached to the conventional louver 1a, and flows smoothly without generating significant vortex. Referring to fig. 4c, when traditional tripe 1a swings to 60, traditional tripe 1a afterbody back air current breaks away from with traditional tripe 1a, produces the swirl, and the swirl is less, produces the noise, and it is stable to influence the air-out, and along with further expansion, the development of swirl, periodic big swirl breaks away from and still can produce surge scheduling problem, influences user experience, and simultaneously, the existence in swirl district still can make traditional tripe 1a both sides appear the difference in temperature, produces the condensation problem.

According to the air outlet component of the indoor unit 100 of the air conditioner, the louver 1 is provided with the plurality of sub-blades 11 which are sequentially connected, the two adjacent sub-blades 11 can rotate relatively, the louver 1 is provided with the multi-section structure, the probability of separation of air flow from the louver 1 is reduced, the air outlet stability is improved, the air outlet noise is reduced, and surging and the like are effectively avoided. Meanwhile, the temperature difference caused by the vortex area on the two sides of the louver 1 can be reduced, and the generation of condensation is reduced. In addition, the pressure loss caused by the fact that the front of the incoming flow impacts the louver 1 can be reduced, and the flow of the outlet air flow is increased. Furthermore, the multi-section louver 1 occupies a small space, and can sweep wind in a wider range, so that the use experience of a user is better.

In some embodiments of the utility model, two adjacent sub-blades 11 are connected by a pivot assembly 12. Specifically, the pivot assembly 12 may include a pivot shaft 121 and a pivot hole 122, the pivot shaft 121 may be formed on one of the two adjacent sub-blades 11, and the pivot hole 122 may be formed on the other of the two adjacent sub-blades 11. The pivot shaft 121 is matched with the pivot hole 122, so that the adjacent two sub-vanes 11 can rotate relatively. Simple structure and convenient processing.

For example, in the example of fig. 1a, the pivot shaft 121 is provided on the sub-blade 11 (i.e., the first sub-blade) near the air intake side, and the pivot hole 122 is formed on the sub-blade 11 (i.e., the second sub-blade) near the air discharge side. Wherein, the number of the pivot shaft 121 and the pivot hole 122 is two. The two pivot shafts 121 may be disposed at intervals in a width direction (e.g., an up-down direction in fig. 2) of the first sub-blade, and the two pivot holes 122 may be disposed at intervals in a width direction of the second sub-blade. Therefore, the relative rotation between two adjacent sub-blades 11 can be conveniently realized, and the structure is simple and the processing is convenient.

It is understood that in other embodiments of the present invention, the pivot axis 121 may also be formed at one end of the first sub-vane adjacent to the second sub-vane, and the pivot axis 121 may be formed in an elongated structure extending along the width direction of the sub-vane 11. In this way, the relative rotation between two adjacent sub-blades 11 can be conveniently realized, and the structure is simple and the processing is convenient.

According to some embodiments of the present invention, the sub-blade 11 closest to the air-out side among the plurality of sub-blades 11 is connected to a link. Specifically, the sub-blades 11 closest to the air-out side in each louver 1 are connected to the connecting rods. Thus, when the driving mechanism drives the connecting rod to move, the sub-blade 11 closest to the air outlet side swings left and right under the driving of the connecting rod. Because two adjacent sub-blades 11 can rotate relatively, the sub-blade 11 can drive the sub-blade 11 adjacent to the sub-blade to swing when swinging, thereby realizing the swinging of the louver 1.

Meanwhile, the sub-blade 11 closest to the air outlet side in the plurality of sub-blades 11 is connected with the connecting rod, in the direction from the air outlet side to the air inlet side, the moment of the sub-blade 11 is gradually increased, so that the swing angle of each sub-blade 11 can be gradually reduced and changed, thereby the whole line of the louver 1 can be more smooth, the air flow is more tightly attached to the louver 1, the probability of the louver 1 being separated from the air flow is further reduced, the air flow stability when the louver 1 swings left and right is improved, the air outlet flow rate can be increased, and the air outlet noise is reduced.

In some embodiments of the present invention, the sub-blade 11 closest to the air-out side may be provided with a connector 14. The connecting rod may be snap-fit connected to the connecting member 14. Referring to fig. 1a, the connection member 14 may be disposed at one side of the sub-blade 11 in the width direction, and has a simple structure and convenient connection.

According to some embodiments of the present invention, the sub-blade 11 closest to the air inlet side among the plurality of sub-blades 11 is rotatably connected to the air-out frame 2. Therefore, the whole swing angle of the louver 1 can be increased, and the flexibility of the louver 1 is improved.

For example, referring to fig. 1 in combination with fig. 1a, the sub-vane 11 closest to the air inlet side may be provided with a catch 13, and the catch 13 may be provided on one side (e.g., the upper side in fig. 1) in the width direction of the sub-vane 11. The air outlet frame 2 can be provided with a clamping hole matched with the clamping buckle 13. The buckle 13 extends into the clamping hole to be rotatably matched with the clamping hole. Therefore, the sub-blades 11 can be rotatably connected to the air outlet frame 2 through the buckles 13, and the fan is simple in structure and convenient to process.

Alternatively, the catch 13 may be an elastic catch. From this, can improve the connection reliability between sub-blade 11 and the air-out frame 2, reduce the noise that factor blade 11 rocked the production, and can reduce the assembly degree of difficulty, improve assembly efficiency.

According to some embodiments of the present invention, the length of the sub-blade 11 close to the air-out side of the two adjacent sub-blades 11 is L1, the length of the sub-blade 11 far from the air-out side of the two adjacent sub-blades 11 is L2, and L1 and L2 satisfy: l1 is more than or equal to 0.5L2 and less than or equal to 1.5L 2.

For example, in some embodiments of the present invention, L1 and L2 may satisfy: L1-0.5L 2, L1-0.8L 2, L1-L2, L1-1.1L 2, L1-1.2L 2, L1-1.3L 2, L1-1.4L 2, L1-1.5L 2, etc. When the length of the sub-blade 11 close to the air-out side is too short, the wind guiding effect of the sub-blade 11 is poor, and when the length of the sub-blade 11 close to the air-out side is too long, the vortex problem caused by the separation of the air flow and the louver 1 cannot be improved. The inventor researches and finds that the length of two adjacent sub-blades 11 is set to be 0.5L 2-1.5L 2-1, so that the wind guide effect of the sub-blades 11 can be ensured, and the vortex problem caused by separation of airflow and the louver 1 can be better improved.

In some further embodiments of the present invention, L1 and L2 satisfy: l1 is more than or equal to L2 and is more than or equal to 0.5L 2. This can further improve the air guiding effect of the sub-blades 11, and can further improve the problem of swirl caused by separation of the airflow from the louver 1.

According to some embodiments of the present invention, an included angle between a sub-blade 11 closest to the air outlet side of the plurality of sub-blades 11 and a normal of a plane where the air outlet 21 is located is 0 to 80 °. That is to say, the included angle between the sub-blade 11 closest to the air outlet side among the plurality of sub-blades 11 and the incoming airflow is 0 to 80 °, that is, the left and right single-side wind swinging angle of the louver 1 is 0 to 80 °. For example, the maximum included angle between the sub-blade 11 closest to the air outlet side among the plurality of sub-blades 11 and the normal of the plane where the air outlet 21 is located may be 45 °, 60 °, 75 °, 80 °, and the like. It can be understood that, the specific value of the maximum included angle between the sub-vane 11 closest to the air outlet side in the plurality of sub-vanes 11 and the normal of the plane where the air outlet 21 is located may be adjusted and designed according to the specific structure and model of the indoor unit 100 of the air conditioner, and this is not specifically limited in this application.

Compared with the one-piece type traditional shutter 1a, the single-side wind swinging angle of the shutter 1 is obviously increased, so that the left and right wind swinging in a wider range can be realized, and the use experience of a user is improved.

According to some embodiments of the present invention, a maximum included angle between the sub-blade 11 closest to the air outlet side of the plurality of sub-blades 11 and a normal of a plane where the air outlet 21 is located is α, that is, a maximum angle at which the sub-blade 11 can swing left and right at a single side is α. The number of the sub-blades 11 is n, and an included angle β between two adjacent sub-blades 11 is: 0.7 alpha/n to 1.3 alpha/n. Wherein the number n of the sub-blades 11 is more than or equal to 2.

It can be understood that each sub-blade 11 swings by an angle, and the size of the angle β between two adjacent sub-blades 11 is influenced by the number of sub-blades 11 and the included angle α. When the included angle alpha is not changed, the more the number n of the sub-blades 11 is, the smaller the included angle beta is, so that the wind-facing angle of the multi-section louver 1 is decomposed, the wind-facing angle between the sub-blades 11 and the airflow is reduced, the airflow near the louver 1 can be attached to the louver 1, the flowing smoothness of the airflow is improved, the risk of separation of the airflow and the louver 1 is reduced, the vortex problem caused by separation of the airflow and the louver 1 is solved, the air outlet stability is improved, the air outlet noise is reduced, and surge and the like are effectively avoided. Meanwhile, the temperature difference caused by the vortex area on the two sides of the louver 1 can be reduced, and the generation of condensation is reduced. In addition, the pressure loss caused by the fact that the front of the incoming flow impacts the louver 1 can be reduced, and the flow of the outlet air flow is increased.

According to some embodiments of the present invention, the sub-blade 11 has a first surface 111 and a second surface 112, and the first surface 111 and the second surface 112 are symmetrically disposed in a thickness direction (e.g., a left-right direction in fig. 2) of the sub-blade 11. Referring to fig. 3 in conjunction with fig. 3a, the first surface 111 and the second surface 112 may be parallel to each other, or the first surface 111 and the second surface 112 may extend toward each other in a direction from the air intake side to the air discharge side. From this, can make the atress on two surfaces of first surface 111 and the second surface 112 of sub-blade 11 more even to can make the air current distribution of the both sides of sub-blade 11 thickness direction more even, and then can improve air-out stability, reduce the difference in temperature between first surface 111 and the second surface 112, reduce the production of condensation.

Meanwhile, the temperature difference caused by the vortex area on the two sides of the louver 1 can be reduced, and the generation of condensation is reduced. In addition, the pressure loss caused by the fact that the front of the incoming flow impacts the louver 1 can be reduced, and the flow of the outlet air flow is increased. Furthermore, the multi-section louver 1 occupies a small space, and can sweep wind in a wider range, so that the use experience of a user is better.
