Detailed Description
Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to like or similar elements or elements having like or similar functions throughout. The embodiments described below by referring to the drawings are illustrative only and are not to be construed as limiting the invention.
An air conditioner 100 according to an embodiment of the present invention is described below with reference to fig. 1 to 14.
Referring to fig. 1 to 8, an air conditioner 100 according to an embodiment of the present invention includes: the device comprises a shell 1, a first wind wheel 2, a second wind wheel 3 and a heat exchanger 4. The air conditioner 100 is provided with an air inlet 101, a first air outlet 102, and a second air outlet 103 spaced apart from each other.
As shown in fig. 3, 7 and 8, a wind mixing cavity 11, a first wind channel 12 and a second wind channel 13 for communicating the wind mixing cavity 11 with the wind inlet 101 are formed in the casing 1, the wind mixing cavity 11 is communicated with the first wind outlet 102 and the second wind outlet 103, that is, the wind mixing cavity 11, the first wind channel 12 and the second wind channel 13 are formed in the casing 1, the first wind channel 12 is used for communicating the wind mixing cavity 11 with the wind inlet 101, the second wind channel 13 is also used for communicating the wind mixing cavity 11 with the wind inlet 101, air can enter the first wind channel 12 through the wind inlet 101 and then enter the wind mixing cavity 11, air can enter the second wind channel 13 through the wind inlet 101 and then enter the wind mixing cavity 11, air entering the wind mixing cavity 11 can flow out of the air conditioner 100 through the first wind outlet 102, and air entering the wind mixing cavity 11 can also flow out of the air conditioner 100 through the second wind outlet 103.
The first wind wheel 2 is rotatably arranged in the first wind channel 12 to drive air to flow from the air inlet 101 towards the air mixing cavity 11, namely, under the drive of the first wind wheel 2, the air is driven to enter the first wind channel 12 through the air inlet 101 and flows to the air mixing cavity 11 through the first wind channel 12.
The second wind wheel 3 is rotatably arranged in the second wind channel 13 to drive air to circulate from the air inlet 101 towards the air mixing cavity 11, namely, under the drive of the second wind wheel 3, the air is driven to enter the second wind channel 13 through the air inlet 101 and flows to the air mixing cavity 11 through the second wind channel 13.
The heat exchanger 4 is disposed in the housing 1 and located at an upstream side of the first air duct 12 and the second air duct 13, so that air entering from the air inlet 101 exchanges heat with the heat exchanger 4 and then enters into the first air duct 12 and the second air duct 13. The "upstream side" described herein is based on the flow direction of the air flow in the housing 1. As shown in fig. 3, 7 and 8, the heat exchanger 4 may be disposed between the air inlet 101 and the air inlet end of the first air duct 12 and the air inlet end of the second air duct 13. Therefore, the air entering the first air channel 12 and the second air channel 13 can be guaranteed to exchange heat with the heat exchanger 4, and the air is prevented from directly entering the first air channel 12 and the second air channel 13 without exchanging heat with the heat exchanger 4 after entering the shell 1 through the air inlet 101.
When the air conditioner 100 works, if the first wind wheel 2 and the second wind wheel 3 work, the first wind wheel 2 drives a part of air to enter the shell 1 through the air inlet 101 to exchange heat with the heat exchanger 4, the air after heat exchange enters the first air duct 12 and flows to the air mixing cavity 11 through the first air duct 12, the second wind wheel 3 drives a part of air to enter the shell 1 through the air inlet 101 to exchange heat with the heat exchanger 4, the air after heat exchange enters the second air duct 13 and flows to the air mixing cavity 11 through the second air duct 13, and the air flowing into the air mixing cavity 11 can flow out through the first air outlet 102 and the second air outlet 103.
It should be noted that, when the air conditioner 100 works, the first wind wheel 2 and the second wind wheel 3 of the present application may work, of course, only one of the first wind wheel 2 and the second wind wheel 3 may work, for example, only the first wind wheel 2 may work and the second wind wheel 3 may not work, at this time, air is driven by the first wind wheel 2 and enters the casing 1 through the air inlet 101 to exchange heat with the heat exchanger 4, the air after heat exchange flows into the air mixing cavity 11 through the first air duct 12, and the air flowing into the air mixing cavity 11 may flow out through the first air outlet 102 and the second air outlet 103;
Or only the second wind wheel 3 works and the first wind wheel 2 does not work, at this time, the air is driven by the second wind wheel 3 to enter the shell 1 through the air inlet 101 to exchange heat with the heat exchanger 4, the air after heat exchange flows into the air mixing cavity 11 through the second air duct 13, and the air flowing into the air mixing cavity 11 can be discharged through the first air outlet 102 and the second air outlet 103.
It can be appreciated that, preferably, the first wind wheel 2 and the second wind wheel 3 both work, so that the heat exchange area of the air duct of the air conditioner 100 is larger, the air conditioner 100 has good refrigeration and heating effects, and the working performance of the air conditioner 100 is improved.
In addition, the position of the air inlet 101 may be arbitrarily selected according to practical needs, for example, as shown in fig. 1-8, the air inlet 101 is disposed on the rear side wall of the housing 1, and the air inlet 101 may be disposed on the top wall, the front wall, the left side wall, the right side wall, or the like of the housing 1.
Similarly, the positions of the first air outlet 102 and the second air outlet 103 may be selected according to practical needs, for example, as shown in fig. 1-8, the first air outlet 102 is disposed on the front wall of the housing 1, the second air outlet 103 is disposed above the top wall of the housing 1, and the first air outlet 102 and the second air outlet 103 may be disposed on the left side wall or the right side wall of the housing 1.
In addition, the air outlet directions of the first air outlet 102 and the second air outlet 103 may be arbitrarily selected according to the needs, the first air outlet 102 may be configured to outlet air in a front side, a left side, a right side, or a top of the air conditioner 100, the second air outlet 103 may be configured to outlet air in a front side, a left side, a right side, or a top of the air conditioner 100, and the air outlet directions of the first air outlet 102 and the second air outlet 103 may be the same, for example, as shown in fig. 8, the air outlet directions of the first air outlet 102 and the second air outlet 103 may be configured to outlet air in front sides of the air conditioner 100, and of course, the air outlet directions of the first air outlet 102 and the second air outlet 103 may be different.
According to the air conditioner 100 provided by the embodiment of the invention, the air mixing cavity 11, the first air duct 12 and the second air duct 13 are arranged, so that the heat exchange area of the air ducts is greatly increased, the air conditioner 100 has good refrigeration and heating effects, and the working performance of the air conditioner 100 is improved. In addition, by providing the first air outlet 102 and the second air outlet 103, the air conditioner 100 can supply air through the two air outlets, and the air supply effect is good. .
In one embodiment of the present invention, the air conditioner further includes a first air deflection assembly 5 for opening or closing the first air outlet 102, and a second air deflection assembly 6 for opening or closing the second air outlet 103. When the first air outlet 102 is closed by the first air deflection assembly 5 and the second air outlet 103 is closed by the second air deflection assembly 6, the air conditioner 100 does not air out at this time, namely, the air conditioner 100 is in a shutdown state at this time; when the first air outlet 102 is opened by the first air deflection assembly 5 and the second air outlet 103 is closed by the second air deflection assembly 6, the air conditioner 100 can only outlet air through the first air outlet 102 (as shown in fig. 3); when the first air outlet 102 is closed by the first air deflection assembly 5 and the second air outlet 103 is opened by the second air deflection assembly 6, the air conditioner 100 can only air out through the second air outlet 103 (as shown in fig. 7); when the first air outlet 102 is opened by the first air deflection assembly 5 and the second air outlet 103 is opened by the second air deflection assembly 6, the air conditioner 100 can discharge air not only through the first air outlet 102 but also through the second air outlet 103 (as shown in fig. 8). By controlling the first air deflection assemblies 5 and the second air deflection assemblies 6, the air conditioner 100 is provided with a plurality of air supply modes.
In one embodiment of the invention, the first rotor 2 is an axial flow rotor (as shown in fig. 3, 7-8) or an diagonal flow rotor, and the second rotor 3 is a centrifugal rotor (as shown in fig. 3, 7-8). It should be noted that, the first wind wheel 2 is not limited to the axial flow wind wheel or the diagonal flow wind wheel, and the first wind wheel 2 may be a centrifugal wind wheel or a cross flow wind wheel. The second wind wheel 3 is not limited to the centrifugal wind wheel, and the second wind wheel 3 may be an axial flow wind wheel, a cross flow wind wheel, an oblique flow wind wheel, or the like.
In one embodiment of the present invention, as shown in fig. 3, 7-8, the first air duct 12 extends in a horizontal direction (front-to-rear direction as shown in the drawings), and the second air duct 13 extends in a vertical direction (up-and-down direction as shown in the drawings). Thus, the air conditioner 100 is compact in internal structure and larger in air duct heat exchange area. Preferably, the second air duct 13 is provided below the first air duct 12.
In one embodiment of the invention, as shown in fig. 3, 7-8, the heat exchanger 4 is vertically disposed within the housing 1. Thus, the air conditioner 100 is compact in internal structure and larger in air duct heat exchange area.
In one embodiment of the present invention, as shown in fig. 4 to 8, the first air outlet 102 is provided on the front panel 18 of the housing 1, and the second air outlet 103 is located above the first air outlet 102. By arranging the first air outlet 102 on the front panel 18 of the casing 1, the first air outlet 102 is air-out towards the front of the air conditioner 100, the air supply distance is short, and the refrigerating or heating effect is good.
The height that second air outlet 103 and first air outlet 102 set up can be selected as required, and preferably, the height of first air outlet 102 is compatible with the height of human body, and the wind that is sent out by first air outlet 102 can directly blow to the region that the human body is located, and the height of second air outlet 103 is higher than the height of human body, and the wind that is sent out by second air outlet 103 blows to the top of human body, then the air current naturally sinks to the region that the human body is located, and the human body will not feel wind sense or the wind sense that feels is lighter this moment, promotes user's comfort. Preferably, as shown in fig. 7 to 8, the second air outlet 103 also outputs air toward the front of the air conditioner 100.
By controlling the first air deflection assemblies 5 and the second air deflection assemblies 6, the air conditioner 100 can realize various air supply modes, and specifically, the air supply modes of the air conditioner 100 can be controlled by the following control methods:
The method comprises the following steps:
the first air outlet 102 is opened by the first air deflector assembly 5, the second air outlet 103 is opened by the second air deflector assembly 6, and both the first air outlet 102 and the second air outlet 103 are air-out;
When the indoor temperature is detected to reach the preset temperature threshold value, the first air deflection assembly 5 is controlled to close the first air outlet 102, and only the second air outlet 103 is used for air outlet at the moment, so that no wind sense and no temperature balancing are realized.
