Description

Wall-mounted air conditioner indoor unit

Technical field

Background technique

In order to save space, household appliances such as air conditioners are becoming more and more miniaturized, but users are increasingly demanding for many aspects such as air supply performance and aesthetic appearance. The traditional wall-mounted air conditioner indoor unit has a single appearance, and the limitation of shape change restricts the improvement of air conditioning performance to a certain extent.

In the prior art, a wall-mounted air conditioner indoor unit usually uses a combination of swing leaves and a wind deflector to guide the air outlet to send air. The wind deflector is driven by the motor to swing forward and backward about its laterally extending rotating shaft, and the swing leaves surround it. The rotating shaft swings left and right, so as to adjust the air supply direction of the air outlet in the up-down direction and the left-right direction. In the existing structure, the size of the air supply range of the air outlet depends on the air deflector and the swing leaf. However, due to the limitation of the casing structure, the swing amplitude of the air deflector and the swing leaf has the maximum limit. Therefore, the air outlet The expansion of the supply air range is also limited.

In addition, the air-conditioning indoor unit achieves the purpose of cooling or heating through the heat exchange between the evaporator and the air. Generally speaking, the larger the area of the evaporator, the higher the efficiency of heat exchange. Traditional wall-mounted air conditioner indoor units use a cross-flow fan to drive the air flow, and the evaporator is wrapped around the outside of the cross-flow fan. In the prior art, it is generally believed that the indoor area of such an indoor unit using a cross flow fan does not have a large evaporator area and low heat exchange efficiency. For this reason, in order to unilaterally pursue a larger evaporator area, some existing technologies have replaced a cross flow fan with an axial flow fan or a centrifugal fan. However, a single axial fan or centrifugal fan cannot meet the normal air supply demand. Multiple axial fans or centrifugal fans need to be installed, and the axial fan has strict requirements on the position of the air inlet. The air duct of the centrifugal fan The structure is relatively complicated, and it takes up space, which results in the structure of this type of wall-mounted air conditioner indoor unit is very complicated, the volume is large, and the operating noise is large.

FIG. 1 is a schematic structural diagram of a wall-mounted air-conditioning indoor unit according to an embodiment of the present invention, and FIG. 2 is a schematic view of a wall-mounted air-conditioning indoor unit according to an embodiment of the present invention. Front view, FIG. 3 is a schematic structural exploded view of a wall-mounted air-conditioning indoor unit according to an embodiment of the present invention, and FIG. 4 is a schematic cross-sectional view of the wall-mounted air-conditioning indoor unit according to an embodiment of the present invention, taken along a horizontal plane.

Referring to FIGS. 1 to 4, the wall-mounted air-conditioning indoor unit 1 of the present invention includes a cabinet 10, and the cabinet 10 is used to form a casing of the wall-mounted air-conditioning indoor unit 1. The casing 10 has an air inlet 11 for introducing indoor air, and an air outlet 12 extending along the lateral direction of the casing 10 and used to send air to the room. The air outlet 12 is provided with two independent air deflectors arranged side by side in the horizontal direction. 131, 132. Each air deflector is configured to be controlled to pivot about its own rotation axis parallel to the extending direction of the air outlet 12 for adjusting the opening and closing state of the air outlet 12 corresponding to the air deflector of the air deflector. And / or wind direction. The rotation axes of the two

wind deflectors

131 and 132 may be collinear or parallel to each other. Specifically, one of the air deflectors 131 may be located on the left side area of the air outlet 12 for adjusting the opening and closing state and / or the air outlet direction of the left side of the air outlet 12; the other air deflector 132 may be located on the air outlet 12 The right region is used to adjust the opening and closing state and / or the direction of the air outlet of the right region of the air outlet 12. The rotation axes of the wind deflector 131 and the wind deflector 132 are both parallel to the extending direction of the air outlet 12. For example, when the air outlet 12 extends in the lateral direction of the cabinet 10, the rotation shafts of the wind deflector 131 and the wind deflector 132 both extend in the lateral direction. Specifically, each of the wind deflectors is an elongated plate material extending in the direction of its rotation axis. Each air deflector is a flat plate to reduce the resistance of the air flow through it and increase the speed of air supply. Alternatively, each of the air deflectors is a curved panel protruding in the middle toward the outside of the casing 10 to guide the airflow to the lower side of the front side of the casing 10 to prevent the airflow from blowing straight down.

In particular, the wall-mounted air-conditioning indoor unit 1 further includes two independent

cross-flow fans

Specifically, the rotating shaft 211 of the cross-flow fan 21 may extend obliquely and forward from one lateral end portion of the casing 10 to the middle portion of the casing 10, and the rotating shaft 221 of the cross-flow fan 22 may extend from the other lateral end portion of the casing 10 to the machine. The middle of the shell 10 extends obliquely forward. In the present invention, a structure gradually slopes or bulges in one direction from one end toward the other end means that the structure has a tendency to slope or bulges in that direction from one end to the other end.

Since the two air deflectors are independent and the two cross-flow fans are also independent, the parameters of the state of each air deflector, as well as the pivoting angle and speed, can be set by the user freely. Parameters such as start-stop status and speed can also be set freely by the user. The combination of the state of the air deflector and the state of the cross-flow fan realizes dual-mode air supply in multiple modes, which meets the different cooling and heating needs of users in different regions, and improves the user experience. In addition, the rotating shafts of the two

cross-flow fans

21 and 22 are specially designed to extend obliquely and forward from the two lateral side ends of the casing 10 to the middle of the casing 10, respectively, so that the outlet air of each cross-flow fan can be made. The directions are directed to the lateral outer front and lower sides of the cabinet 10, which breaks through the limitation on the air supply angle of the cross-flow fan in the prior art and expands the air supply range of the indoor unit.

cross-flow fans

21, 22, the third heat exchange section 33 is on the front side of the two

cross-flow fans

21, 22, and the first heat exchange section 31 and the first Each of the three heat exchange sections 33 is a V-shaped heat exchange section that gradually extends obliquely forward from the lateral ends of the casing 10 to the middle thereof or a curved heat exchange section that gradually protrudes forward and bends. That is to say, the cross sections of the first heat exchange section 31 and the third heat exchange section 33 taken along the horizontal cutting plane are V-shaped or gradually forward that gradually extend forward toward the middle of the casing 10 at both lateral ends. Bent curved arc.

This application breaks through the traditional design idea that the cross-flow fan must be replaced with another fan type in order to increase the area of the evaporator.

In addition, since the first heat exchange section 31 is V-shaped, a substantially triangular or arcuate space can be formed between the first heat exchange section 31 and the skeleton of the cabinet 10, which increases the size of the gap between the two. It is beneficial for the air to pass through the evaporator 30 quickly, reduces the resistance of air flow in the cabinet 10, and reduces the operating noise of the wall-mounted air conditioner indoor unit 1. At the same time, the amount of supplementary air is also increased to a certain extent, thereby increasing the amount of air supplied by the wall-mounted air-conditioning indoor unit 1.
