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 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 drawings are exemplary only for the purpose of explaining the present invention, and should not be construed as limiting the present invention.

An air conditioning indoor unit 100 according to an embodiment of the present invention is described below with reference to the accompanying drawings. Wherein the indoor unit 100 may be a cabinet unit.

As shown in fig. 1-2, an air conditioner indoor unit 100 according to an embodiment of the present invention includes: the air guide device comprises a machine shell 1, a volute 2 and a plurality of air guide assemblies 3.

Specifically, an air outlet 11 and an air inlet 12 are arranged on the machine shell 1, and a heat exchange air duct a communicated with the air outlet 11 and the air inlet 12 is defined in the machine shell 1. Therefore, when the air-conditioning indoor unit 100 exchanges heat, indoor air can enter the heat exchange air duct a in the casing 1 through the air inlet 12, and then exchanges heat with the indoor heat exchanger of the air-conditioning indoor unit 100, and the air after heat exchange is discharged to an indoor space through the air outlet 11, so that the heat exchange function of the air-conditioning indoor unit 100 can be realized through such a cycle.

The volute 2 is arranged in the casing 1 to define at least a part of the heat exchange air duct a, and the volute 2 is provided with a volute tongue portion 21. It can be seen that after passing through the heat exchange air duct a defined by the volute 2, the air flow rate is larger on the side close to the volute tongue portion 21, that is, the air flows toward the side of the volute tongue portion 21. (the unidirectional arrows in FIGS. 1-3 refer to the simulated lines of air flow in the heat exchange air duct a)

The plurality of air guide assemblies 3 are pivotally arranged at the air outlet 11, and each air guide assembly 3 comprises a connecting rod 31 and a plurality of air guide strips 32 arranged on the connecting rod 31 at intervals. Therefore, each wind guide assembly 3 can be pivotally arranged at the air outlet 11 through the connecting rod 31, and the plurality of wind guide strips 32 of each wind guide assembly 3 can be driven to rotate through the connecting rod 31, so that the guiding effect on the air flow can be realized.

The plurality of air guide assemblies 3 have a first position where the plurality of air guide assemblies 3 are located on the same plane in the left-right direction and a second position. In the second position, at least one air guide assembly 3 can move backward so that at least two air guide assemblies 3 are arranged at intervals in the front-back direction. The left-right direction refers to a direction of the outlet 11 parallel to the ground after the air conditioning indoor unit 100 is installed. For example, when the air conditioning indoor unit 100 is a cabinet, the width direction of the outlet 11 is the left-right direction. When the air conditioning indoor unit 100 is on-hook, the length direction of the outlet 11 is the left-right direction.

As can be seen from this, in the plurality of air guide assemblies 3, after the air guide assembly 3 moving rearward moves from the first position to the second position, the air guide assembly 3 can block the airflow in the heat exchange air duct a from flowing toward the volute portion 21 to some extent, and further, more airflow can be moved in the air guide direction of the air guide strips 32 on the air guide assembly 3, thereby increasing the air guide amount of the air guide assembly 3. Since the distances between the plurality of air guide strips 32 on the same air guide assembly 3 are fixed, that is, the air guide areas between the plurality of air guide strips 32 are fixed, when the air guide amount of the air guide assembly 3 is increased, the flow speed of the air current flowing through the air guide assembly 3 can be increased, and the air supply distance of the air-conditioning indoor unit 100 is increased to a certain extent, so that the air-conditioning indoor unit 100 can supply air to a region with a longer distance, which is beneficial for a user moving in the space where the air-conditioning indoor unit 100 is located to feel cooling or heating more quickly. The comfort of the user is improved, and the use experience of the user is improved.

It can be understood that, when the plurality of air guide assemblies 3 are arranged side by side in the left-right direction, and the air guide assembly 3 on one side close to the volute portion 21 in two adjacent air guide assemblies 3 moves backward to be arranged at an interval with another air guide assembly 3 in the front-rear direction, the air guide assembly 3 moving backward can block the airflow in the heat exchange air duct a from flowing toward one side of the volute portion 21 to a certain extent, and further more airflows can move along the air guide direction of the air guide strips 32 on the air guide assembly 3, and the air guide amount of the air guide assembly 3 is increased. Meanwhile, the air guiding amount between the adjacent air guiding strips 32 of the two adjacent air guiding assemblies 3 close to each other is increased more (because the air guiding strips 32 of the air guiding assembly 3 positioned at the front side do not increase the blocking effect on the air flow, but the air guiding strips 32 of the air guiding assembly 3 close to the front side in the air guiding assembly 3 moving backwards block the air flow with a certain air volume and enable the blocked air flow to flow along the air guiding strips 32 close to each other of the two air guiding assemblies 3), so that compared with the first position, the air guiding area between the two air guiding strips 32 is unchanged, but the air guiding amount is increased obviously, the air flow between the two air guiding strips 32 is effectively increased, the pressure between the two air guiding strips 32 is increased, the flow speed of the air flow between the two air guiding strips 32 is increased, the air supply distance of the indoor unit 100 of the air conditioner can be increased, and the indoor unit 100 of the air conditioner can supply air to a region with, it is advantageous for a user who moves in the space where the indoor unit 100 of the air conditioner is located to feel cool or hot more quickly. The comfort of the user is improved, and the use experience of the user is improved.

Therefore, when the air guide strips 32 of the plurality of air guide assemblies 3 are arranged in a crossing manner, the air guide amount of the corresponding plurality of air guide assemblies 3 can be more effectively increased, so that high pressure regions with high air flow pressure are formed among more air guide strips 32, and the air supply distance of the air-conditioning indoor unit 100 can be effectively increased.

according to the utility model discloses indoor unit of air conditioner 100, through making a plurality of air guide assembly 3 have primary importance and second position, at the primary importance, in the left right direction, a plurality of air guide assembly 3 are located the coplanar. In the second position, at least one air guide assembly 3 can move backward so that at least two air guide assemblies 3 are arranged at intervals in the front-back direction. Therefore, the air guide assembly 3 can block a part of the airflow flowing towards the volute tongue portion 21, the flowing speed of the airflow flowing through the air guide assembly 3 can be further improved, the air supply distance of the air-conditioning indoor unit 100 is increased to a certain extent, the air-conditioning indoor unit 100 can supply air to a region with a longer distance, and a user moving in a space where the air-conditioning indoor unit 100 is located can feel cool or hot more quickly. The comfort of the user is improved, and the use experience of the user is improved.

As shown in fig. 2, according to some embodiments of the present invention, the wind guide strips 32 of at least a part of the at least two wind guide assemblies 3 are arranged to intersect in the left-right direction. Therefore, the air guiding amount of the corresponding air guiding assembly 3 can be effectively increased, and high pressure regions with higher air flow pressure are formed among more air guiding strips 32, so that the air supply distance of the indoor unit 100 of the air conditioner can be effectively increased. When the plurality of air guide assemblies 3 are all arranged in an intersecting manner, the side of each air guide strip 32 on the front air guide assembly 3 close to the tongue portion 21 is an air pressure high pressure region, and the side of each air guide strip 32 far from the tongue portion 21 is a negative pressure region. For example, as shown in fig. 2 to 3, two air guide assemblies 3 are provided, and the two air guide assemblies 3 are arranged to intersect with each other. The volute tongue portion 21 is located on the left side of the heat exchange air duct a, after the air guide assembly 3 located on the left side moves backwards, the air flow on the left side of each air guide strip 32 in the air guide assembly 3 located on the front side is increased, namely, the air pressure region is high, and the air flow on the right side of each air guide strip 32 is decreased (a part of the air flow which should flow into the space on the right side of the air guide strip 32 originally is shielded by the air guide strip 32 in the air guide assembly 3 moving backwards), namely, the air pressure region is low.

Alternatively, as shown in fig. 2, the wind guide strips 32 of the plurality of wind guide assemblies 3 are all arranged in a crossing manner. The air blowing distance of the air conditioning indoor unit 100 can be further increased.

The structure of an indoor unit 100 for an air conditioner according to an embodiment of the present invention will be described in detail with reference to fig. 1 to 4. It should be noted that the following description is only exemplary, and it is obvious that a person skilled in the art may combine, replace, modify and/or modify the technical solutions or some technical features of the present invention after reading the following technical solutions of the present invention, which also falls into the protection scope of the present invention.

as shown in fig. 1 to 4, the indoor air conditioner 100 includes: the air-conditioning device comprises a machine shell 1, a volute 2, an air guide component 3, a louver 4, an air inlet grille 5 and a filter screen component 6. The indoor air conditioner 100 is a cabinet.

An air outlet 11 and an air inlet 12 are arranged on the machine shell 1, and a heat exchange air duct a communicated with the air outlet 11 and the air inlet 12 respectively is defined in the machine shell 1. The volute 2 is arranged in the casing 1 to define a part of the heat exchange air duct a, and the volute 2 is provided with a volute tongue portion 21, and the volute tongue portion 21 is positioned at the left side of the heat exchange air duct a. The number of the air guide assemblies 3 is two, each air guide assembly 3 comprises a connecting rod 31 and three air guide strips 32 arranged on the connecting rod 31 at intervals, and each air guide assembly 3 is pivotally arranged on the machine shell 1 through the connecting rod 31 and is positioned at the air outlet 11. In the thickness direction perpendicular to the axial direction of the air guide strips 32, the maximum thickness value of each air guide strip 32 is b, and b satisfies: b is more than or equal to 4mm and less than or equal to 8 mm.

The two air guide assemblies 3 have a first position and a second position, as shown in fig. 1, in the first position, in the left-right direction, the two air guide assemblies 3 are located in the same plane, and the air guide strips 32 of the two air guide assemblies 3 are arranged in a crossed manner; as shown in fig. 2, in the second position, the left air guide assembly 3 is movable rearward so that the two air guide assemblies 3 are spaced apart in the front-rear direction. And the left air guide assembly 3 can also move in the left-right direction.

As shown in fig. 1 and 2, in the embodiment of the present invention, the air guide assembly 3 located on the left side is a first air guide assembly, and the air guide assembly 3 located on the right side is a second air guide assembly. The three wind guide strips 32 of the first wind guide assembly are named as a first wind guide strip, a second wind guide strip and a third wind guide strip in the left-to-right direction. Three air guide strips of the second air guide assembly 3 are named as a fourth air guide strip, a fifth air guide strip and a sixth air guide strip. When the two air guide assemblies 3 are in the first position, the first air guide strip, the fourth air guide strip, the second air guide strip, the fifth air guide strip, the third air guide strip and the sixth air guide strip are respectively arranged in the left-to-right direction. The distance between two adjacent wind guide strips 32 is equal.

when the first air guiding assembly is in the first position, the first air guiding assembly moves backwards to enable the first air guiding assembly and the second air guiding assembly to be arranged at intervals in the front-back direction. At this time, the positional relationship between the first wind guide strip and the sixth wind guide strip is not changed in the left-to-right direction, and the first wind guide strip, the fourth wind guide strip, the second wind guide strip, the fifth wind guide strip, the third wind guide strip, and the sixth wind guide strip remain.

Because the second air guiding assembly moves backwards and the volute tongue portion 21 is located on the left side of the heat exchange air duct a, the first air guiding strip, the second air guiding strip and the third air guiding strip on the second air guiding assembly can respectively block a part of air flow flowing leftwards, so that the blocked air flow flows along the air guiding direction of the air guiding assembly 3. Specifically, the airflow blocked by the first air guiding strip may flow out to the indoor unit 100 of the air conditioner along a gap between the first air guiding strip and the fourth air guiding strip. The air flow blocked by the second air guiding strip can flow out to the indoor unit of air conditioner 100 along the gap between the second air guiding strip and the fifth air guiding strip. The air flow blocked by the third air guiding strip can flow out to the indoor unit of air conditioner 100 along the gap between the third air guiding strip and the sixth air guiding strip. Therefore, compared with the two air guiding assemblies 3 in the first position, the air flow between the first air guiding strip and the fourth air guiding strip is increased, that is, the air pressure is increased to form a high pressure area (for example, the area between the two air guiding strips 32 in fig. 3 is the high pressure area). The air flow between the second air guide strips and the fifth air guide strips is increased, namely, the air pressure is increased to form a high-pressure area. The air flow between the third air guide strip and the sixth air guide strip is increased, namely, the air pressure is increased to form a high-pressure area. Therefore, the flow speed of the airflow flowing between the first air guide strip and the fourth air guide strip, between the second air guide strip and the fifth air guide strip and between the third air guide strip and the sixth air guide strip can be increased, the air supply distance of the indoor air conditioner unit 100 can be effectively increased, the indoor air conditioner unit 100 can supply air to a region with a longer distance, and a user moving in a space where the indoor air conditioner unit 100 is located can feel cool or hot more quickly. The comfort of the user is improved, and the use experience of the user is improved.

When the two air guiding assemblies 3 are in the second position, the first air guiding strip blocks part of the air flow flowing leftward, so that the air flow flowing through the left side of the first air guiding strip and close to the first air guiding strip is reduced to some extent, and the air flow on the left side of the first air guiding strip is reduced, that is, the air pressure is reduced to form a negative pressure region (for example, the region on the left side of the left air guiding strip 32 in fig. 3 is a negative pressure region). Since the second air guiding strip blocks part of the air flow flowing leftwards, the air flow flowing between the second air guiding strip and the fourth air guiding strip is reduced to a certain extent, so that the air flow between the second air guiding strip and the fourth air guiding strip is reduced, namely, the air pressure is reduced to form a negative pressure area (for example, the area on the right side of the air guiding strip 32 on the right side in fig. 3 is a negative pressure area). Because the third air guide strip blocks part of the air flow flowing leftwards, the air flow flowing between the third air guide strip and the fifth air guide strip is reduced to a certain extent, and the air flow between the third air guide strip and the fifth air guide strip is reduced, namely, the air pressure is reduced to form a negative pressure area.
