Specifically, the air-conditioning indoor unit comprises any one of a floor-type air-conditioning indoor unit, a wall-mounted air-conditioning indoor unit and a ceiling-mounted air-conditioning indoor unit. The details will be described below by taking a floor type air conditioner indoor unit as an example.
Referring to fig. 1 to 4, an air conditioner 100 according to the present invention includes a housing 10, a partition 50 and a fan assembly. The housing 10 has an air duct 11, the housing 10 includes a front panel 13 and a back panel 12, and the back panel 12 is provided with an air inlet 121 communicated with the air duct 11. The partition plate 50 is installed in the air duct, the air inlet 121 is divided into an upper air inlet area and a lower air inlet area by the partition plate 50, the air duct 11 is divided into a first air chamber 11a and a second air chamber 11b, the first air chamber 11a is communicated with the upper air inlet area, and the second air chamber 11b is communicated with the lower air inlet area by the partition plate 50. A first air outlet 131 and a second air outlet 132 are formed in the front panel 13, the first air outlet 131 is communicated with the first air cavity 11a, and the second air outlet 132 is communicated with the second air cavity 11b. The fan assembly comprises a first fan 20a and a second fan 20b, the first fan 20a is arranged in the first air cavity 11a and corresponds to the first air outlet 131, and the second fan 20b is arranged in the second air cavity 11b and corresponds to the second air outlet 132.
Specifically, the housing 10 is disposed in a square shape, but the housing 10 may also be disposed in a circular shape, which is not limited herein, and will be described as a square cabinet. For convenience of detachment and installation, the housing 10 may be provided in a separate manner, and certainly, the housing 10 may also be provided in an integrally formed manner, which is not limited herein. The back plate 12 is provided with a strip-shaped air inlet 121 (as shown in fig. 1) extending in the vertical direction, and an air inlet grille is arranged at the air inlet 121. The front panel 13 is provided with a first air outlet 131 and a second air outlet 132 which are arranged at an interval in the vertical direction, and the shapes of the first air outlet 131 and the second air outlet 132 are not particularly limited, for example, the air outlets may be square air outlets, circular air outlets, or air outlets with other shapes such as oval air outlets.
The air duct 11 is formed in the housing 10, and air enters the air duct 11 from the air inlet 121, exchanges heat with the heat exchanger 30 in the air duct 11, and is blown out through the first air outlet 131 and the second air outlet 132, so as to adjust the temperature of indoor air. The partition plate 50 is disposed in the air duct 11 and extends in the front-back direction, and the partition plate 50 is correspondingly disposed between the first air outlet 131 and the second air outlet 132, so as to divide the air duct 11 into a first air cavity 11a communicated with the first air outlet 131 and a second air cavity 11b communicated with the second air outlet 132. Here, the partition plate 50 completely separates the first air cavity 11a from the second air cavity 11b, so that air robbery in the case of simultaneous operation of the upper and lower two sets of fans is effectively avoided. Moreover, the partition plate 50 divides the air inlet 121 extending in the up-down direction into an upper air inlet area and a lower air inlet area, so that the air entering from the upper air inlet area can only enter the first air chamber 11a and is blown out through the first air outlet 131; the air entering from the lower air inlet area can only enter the second air chamber 11b and is blown out through the second air outlet 132. Therefore, the vortex caused by the air robbery between the first air cavity 11a and the second air cavity 11b can be effectively avoided, so that the air volume of the secondary air outlets (the first air outlet 131 and the second air outlet 132) is improved, and the noise is reduced.
In the embodiment of the present invention, the first fan 20a is mainly used for driving air to enter the first air cavity 11a from the upper air inlet area, and then to be blown out through the first air outlet 131; the second fan 20b is mainly used for driving air to enter the second air chamber 11b from the lower air inlet area and then blow out through the second air outlet 132. The specific structure of the first fan 20a and the second fan 20b is not limited, for example, the first fan 20a may include an axial flow wind wheel or a centrifugal wind wheel, and the second fan 20b may also include an axial flow wind wheel or a centrifugal wind wheel. Taking the axial flow wind wheel as an example, the number of the axial flow wind wheels included in the first fan 20a may be one, two, or three, and the like, and similarly, the number of the axial flow wind wheels included in the second fan 20b may also be one, two, or three, and the like. As such, there are various combinations of the first fan 20a and the second fan 20b, for example, the first fan 20a includes one axial flow wind wheel, and the second fan 20b includes two axial flow wind wheels; or the first fan 20a comprises two axial flow wind wheels, and the second fan 20b comprises two axial flow wind wheels; or the first fan 20a comprises two axial flow wind wheels, and the second fan 20b comprises three axial flow wind wheels. It is not particularly limited and will be described in detail hereinafter.
According to the technical scheme, the partition plate 50 is arranged, the air inlet 121 of the air conditioner 100 is divided into the upper air inlet area and the lower air inlet area which are distributed in the vertical direction, the air duct 11 of the air conditioner 100 is divided into the first air cavity 11a communicated with the upper air inlet area and the second air cavity 11b communicated with the lower air inlet area, the first fan 20a is arranged in the first air cavity 11a, and the second fan 20b is arranged in the air cavities, so that the problems of low air volume and high noise caused by air snatching when two groups of fans operate simultaneously can be effectively avoided.
There are various structures of the partition 50, for example, in this embodiment, referring to fig. 3, the partition 50 is disposed in a flat plate shape. The front end of the partition 50 may be connected to the front panel 13, and the rear end of the partition 50 may be connected to the back panel 12, so that the partition 50 divides the air duct 11 into two first air chambers 11a and two second air chambers 11b which are separated from each other.
In another embodiment, referring to fig. 5, the thickness of the partition 50 gradually increases from back to front. Wherein the cross section of the partition 50 may be a right triangle, an equilateral triangle, a trapezoid, etc. Preferably, the cross section of the partition 50 is an equilateral triangle, so that the partition 50 has an upward inclined upper flow guiding surface and a downward inclined lower flow guiding surface, and since the partition 50 is correspondingly located between the first air outlet 131 and the second air outlet 132, the upper flow guiding surface of the partition 50 can guide the air flow entering from the lower end of the upper air inlet area to the air inlet side of the first fan 20 a; the lower guide surface of the partition 50 guides the air flow entering from the upper end of the lower air intake area to the air intake side of the second fan 20 b. In this way, the air flow can be prevented from being located in the intake dead zone of the first fan 20a or the second fan 20b, and the efficiency of the first fan 20a and the second fan 20b is improved.
Referring to fig. 3 and 4, the air conditioner 100 further includes a heat exchanger 30 disposed in the air duct 11. The installation manner of the heat exchanger 30 may be various, and specifically, the following are provided:
in one way, the heat exchanger 30 is attached to the back plate 12 to cover the air inlet 121, and the rear end of the partition plate 50 is connected to the heat exchanger 30 (as shown in fig. 3). Thus, the air entering from the air inlet 121 exchanges heat with the heat exchanger 30, the air exchanging heat with the upper portion of the heat exchanger 30 enters the first air chamber 11a, and the air exchanging heat with the lower portion of the heat exchanger 30 enters the second air chamber 11b.
In a second mode, the heat exchanger 30 is spaced apart from the back plate 12 and is located behind the first fan 20a and the second fan 20 b. Thus, a part of the air entering the first air chamber 11a from the upper air inlet area is subjected to heat exchange by the heat exchanger 30 and then blown out through the first air outlet 131, and the other part of the air is directly blown out through the first air outlet 131; air entering the second air chamber 11b from the lower air inlet area is partially blown out through the second air outlet 132 after heat exchange is performed by the heat exchanger 30, and the other part of air is directly blown out through the second air outlet 132. In this way, the temperature of the air blown by the air conditioner 100 is not too high or too low, so that the comfort of the user can be improved.
There are also various structures of the heat exchanger 30, and there is no particular limitation thereto. In the present embodiment, the heat exchanger 30 is a straight-line heat exchanger, and the heat exchanger 30 extends in the vertical direction. It will be appreciated that in another embodiment, the heat exchanger 30 is a V-shaped heat exchanger, and the heat exchanger 30 has a convex portion that projects toward the back plate 12. Of course, in yet another embodiment, the heat exchanger 30 may also be a U-shaped heat exchanger.
In a preferred embodiment, the heat exchanger 30 may further include a first sub-heat exchanger disposed above the partition 50, and a second sub-heat exchanger disposed below the partition 50.
Various combinations of the first sub heat exchanger and the second sub heat exchanger are possible, for example, in one embodiment, the first sub heat exchanger is attached to the back plate 12 to cover the upper intake area, and/or the second sub heat exchanger is attached to the back plate 12 to cover the lower intake area. Specifically, the first sub heat exchanger is combined with the back plate 12 to cover the upper air inlet area, and the second sub heat exchanger is located behind the second fan 20b and spaced from the back plate 12; or, the second sub heat exchanger is combined with the back plate 12 to cover the lower air intake area, and the first sub heat exchanger is located at the rear side of the first fan 20a and spaced from the back plate 12; or, the first sub heat exchanger is combined with the back plate 12 to cover the upper air inlet area, and the second sub heat exchanger is combined with the back plate 12 to cover the lower air inlet area. Of course, in another embodiment, the first sub heat exchanger is located behind the first fan 20a and spaced from the back plate 12, and the second sub heat exchanger is located behind the second fan 20b and spaced from the back plate 12.
Further, the air conditioner 100 further includes an electric control board (not shown) connecting the first sub heat exchanger and the second sub heat exchanger to control operations of the first sub heat exchanger and the second sub heat exchanger. So, can be according to user's needs, select different air-out effects. For example, when refrigerating, the first sub heat exchanger can be controlled to operate, and the second sub heat exchanger is controlled to stop operating, so that on one hand, long-distance air supply can be realized, on the other hand, the air outlet quantity can be reduced, and the indoor temperature is prevented from being too low. When heating, steerable first sub heat exchanger stop operation to and the operation of control second sub heat exchanger, can make indoor upper and lower floor's temperature more even on the one hand like this, on the other hand also can reduce the air output, prevents that indoor temperature is too high. By independently controlling the operation of the first sub heat exchanger and the second sub heat exchanger, the heat exchange efficiency of the heat exchanger 30 is improved, and unnecessary waste is reduced.
On the basis of the above embodiments, referring to fig. 3, an installation plate 40 extending in the vertical direction is disposed in the air duct 11, and a first installation opening corresponding to the first air outlet 131 and a second installation opening corresponding to the second air outlet 132 penetrate through the installation plate 40.
In order to facilitate the assembly and disassembly of the first fan 20a and the second fan 20b, the air conditioner 100 further includes a first housing 41 for the first fan 20a to be mounted and a second housing 42 for the second fan 20b to be mounted. The air inlet end of the first housing 41 is connected to the first mounting port, the air outlet end of the first housing 41 is connected to the first air outlet 131, the air inlet end of the second housing 42 is connected to the second mounting port, and the air outlet end of the second housing 42 is connected to the second air outlet 132.
Specifically, the first housing 41 and the second housing 42 are both cylindrical and have two open ends. Taking the first housing 41 as an example, the first housing 41 may be cylindrical or square cylindrical, and is not limited herein. The first housing 41 may be integrally formed on the mounting plate 40, or may be detachably mounted on the mounting plate 40, which is not limited herein.
Referring to fig. 3, the partition plate 50 is located at the rear side of the mounting plate 40 and is connected to the mounting plate 40. Thus, the air entering the first air cavity 11a from the upper air inlet region enters the first casing 41 through the air inlet end of the first casing 41, and finally is blown out from the first air outlet 131; the air entering the second air chamber 11b from the lower air inlet region enters the second casing 42 through the air inlet end of the second casing 42, and finally is blown out from the second air outlet 132.
The partition plate 50 and the mounting plate 40 may be integrally formed. Of course, the partition board 50 and the mounting plate 40 may be detachably connected, for example, the partition board 50 and the mounting plate 40 are magnetically attracted to each other, or the partition board 50 and the mounting plate 40 are snap-connected to each other.
In addition to the above embodiments, in order to increase the air blowing distance and reduce noise, at least one of the first fan 20a and the second fan 20b may be a counter-rotating fan.
Specifically, the counter-rotating fan includes a first axial wind wheel 21 and a second axial wind wheel 22 which are coaxially arranged, the rotation direction of the first axial wind wheel 21 is opposite to the rotation direction of the second axial wind wheel 22, and the air supply direction of the first axial wind wheel 21 is the same as the air supply direction of the second axial wind wheel 22.
In a preferred embodiment, the first fan 20a and the second fan 20b are counter-rotating fans.
