Wherein, two indoor air inlets 12 can be arranged on the front surface 14 of the inner shell; or one of the indoor air outlets 13 is arranged on the front surface 14 of the inner shell, and the other indoor air outlet 13 is arranged on the side surface 15 of the inner shell; or one of the indoor air outlets 13 is arranged on the front surface 14 of the inner shell, and the other indoor air outlet 13 is arranged on the back surface 16 of the inner shell.
In another embodiment, at least one indoor air intake 12 is provided in the inner casing side 15 of the inner casing 10. That is, when one indoor air inlet 12 is provided, the indoor air inlet 12 is provided on the inner casing side surface 15, and when two or more indoor air inlets 12 are provided, at least one indoor air inlet 12 is provided on the inner casing side surface 15. When indoor air outlet 13 locates inner shell openly 14, so can make the interval between indoor air outlet 13 and the indoor air intake 12 far away, and make indoor air outlet 13 and indoor air intake 12 respectively towards different directions, can reduce the air-out air current that blows off from indoor air outlet 13 and directly inhaled the possibility of indoor air intake 12, can also promote the circulation effect of room air, realize the abundant circulation heat transfer of room air. The two indoor air inlets 12 may be disposed on the inner casing side surface 15, at this time, two indoor air inlets 12 may be disposed on two side surfaces of the inner casing 10, the two indoor air ducts 11 are communicated with the two indoor air inlets 12 in a one-to-one correspondence, or two indoor air inlets 12 may be disposed on each inner casing side surface 15, one indoor air inlet 12 is disposed on each of the two inner casing side surfaces 15 and is communicated with one of the indoor air ducts 11, and the other indoor air inlets 12 of the two inner casing side surfaces 15 are communicated with the other indoor air duct 11. Or one of the indoor air outlets 13 is arranged on the side surface 15 of the inner shell, and the other indoor air outlet 13 is arranged on the back surface 16 of the inner shell.
In another embodiment, all of the indoor air inlets 12 may be disposed on the back surface 16 of the inner casing. That is, when one indoor air inlet 12 is provided, the indoor air inlet 12 is provided on the back surface 16 of the inner casing, and when two or more indoor air inlets 12 are provided, all the indoor air inlets 12 are provided on the back surface 16 of the inner casing.

In one embodiment, the air inlet side of the axial flow wind wheel 22 is disposed toward the indoor air inlet 12. That is, the indoor air inlet 12 is disposed at the position of the inner machine casing 10 facing the air inlet side of the axial flow wind wheel 22, so that the distance between the air inlet side of the axial flow wind wheel 22 and the indoor air inlet 12 is small, which is beneficial to shortening the air inlet path and the air duct path between the indoor air inlet 12 and the indoor air outlet 13. Of course, in other embodiments, the indoor air inlet 12 and the air inlet side of the axial flow wind wheel 22 may be arranged at an interval in the vertical direction.
In one embodiment, the axis of the axial flow wind wheel 22 extends in the front-rear direction. That is, the air inlet side of the axial flow wind wheel 22 is arranged towards the rear side of the inner casing 10, the air outlet side of the axial flow wind wheel 22 is arranged towards the front side of the inner casing 10, and the indoor air outlet 13 is arranged on the front side 14 of the inner casing. Since the axial flow wind wheel 22 is small in axial dimension, the dimension in the front-rear direction in the inner machine casing 10 can be reduced. And the space in the left-right direction and the up-down direction in the inner machine casing 10 can be fully utilized, so that the radial dimension of the axial flow wind wheel 22 is larger, and the air supply quantity of the axial flow wind wheel 22 is increased. Of course, in other embodiments, the indoor air intake 12 may be disposed on the inner shell side 15. In addition, in other embodiments, the axis of the axial flow wind wheel 22 may also extend in the left-right direction.
In one embodiment, the axis of the cross-flow wind wheel 21 extends in the left-right direction. Therefore, the indoor air outlet 13 can be arranged at a higher position of the inner machine shell 10 (for example, the indoor air outlet 13 is positioned above the cross-flow wind wheel 21), and in the cooling mode, as the cold air flow can flow downwards after being sent out from the indoor air outlet 13, when the indoor air outlet 13 is arranged at the higher position of the inner machine shell 10, the cold air flow can be sent out from the upper side as much as possible, so that the cold air flow can be better distributed indoors. The indoor air outlet 13 may also be disposed at a lower position of the inner machine casing 10 (for example, the indoor air outlet 13 is located below the cross flow wind wheel 21), and in the heating mode, since the hot air flows upward after being sent out from the indoor air outlet 13, when the indoor air outlet 13 is disposed at the lower position of the inner machine casing 10, the hot air can be sent out from the lower position as much as possible, so that the hot air can be better distributed indoors. Of course, in other embodiments, the axis of the cross-flow wind wheel 21 may also extend in the up-down direction.
In an embodiment, an indoor air inlet 12 is disposed at a position of the internal machine casing 10 corresponding to an air inlet side of the cross flow wind wheel 21. That is, the air inlet side of the cross flow wind wheel 21 is arranged towards the indoor air inlet 12, so that the distance between the air inlet side of the cross flow wind wheel 21 and the indoor air inlet 12 is small, and the air inlet path and the air duct path between the indoor air inlet 12 and the indoor air outlet 13 are favorably shortened. Of course, in other embodiments, the indoor air inlet 12 and the air inlet side of the cross flow wind wheel 21 may be arranged at an interval in the vertical direction or the horizontal direction.
In one embodiment, the inner machine casing 10 is provided with an indoor air inlet 12 at a position corresponding to the air inlet side of the axial flow wind wheel 22. That is, the air inlet side of the axial flow wind wheel 22 is arranged towards the other indoor air inlet 12, so that the distance between the air inlet side of the axial flow wind wheel 22 and the indoor air inlet 12 is smaller, and the air inlet path and the air duct path between the indoor air inlet 12 and the indoor air outlet 13 are favorably shortened. Of course, in other embodiments, the indoor air inlet 12 and the air inlet side of the axial flow wind wheel 22 may be arranged at an interval in the up-down direction or the left-right direction.
In an embodiment, an air outlet duct 17 is formed between the cross flow wind wheel 21 and the indoor air outlet 13, and in the air outlet direction, the cross-sectional area of the air outlet duct 17 perpendicular to the air outlet direction is gradually increased. In the air-out direction, the size in air-out wind channel 17 increases gradually promptly, so can promote the diffusion effect of air-out air current to can increase the air supply scope. In the embodiment that the axis of the cross flow wind wheel 21 extends in the left-right direction, the distance between two wind channel walls opposite to the wind outlet channel 17 and parallel to the axis of the cross flow wind wheel 21 is gradually increased in the wind outlet direction, so as to better match the wind outlet side of the cross flow wind wheel 21, and thus the air supply range can be better increased. Of course, in other embodiments, the sizes of the air outlet duct 17 may be substantially the same.
In one embodiment, an air outlet duct 17 is formed between the cross flow wind wheel 21 and the indoor air outlet 13, and in the air outlet direction, the air outlet duct 17 gradually inclines towards a direction away from the other indoor air outlet 13. That is, in the air outlet direction, the air outlet duct 17 is gradually inclined toward the direction away from the axial flow wind wheel 22. Therefore, the distance between the indoor air outlet 13 corresponding to the cross-flow wind wheel 21 and the indoor air outlet 13 corresponding to the axial-flow wind wheel 22 is relatively long, and the air supply range can be further enlarged. For example, when the cross flow wind wheel 21 is disposed above the axial flow wind wheel 22, that is, the air outlet duct 17 extends obliquely upward, so that the airflow sent out from the indoor air outlet 13 above can be sent to a higher position indoors, which is beneficial to improving the air supply effect in the cooling mode. When the cross flow wind wheel 21 is arranged below the axial flow wind wheel 22, namely the air outlet duct 17 extends obliquely downwards, the airflow sent out from the indoor air outlet 13 below can be better sent to the bottom surface, and the air supply effect in the heating mode can be improved. In the embodiment where the indoor air inlet 12 is located between the two indoor air outlets 13, such that the outlet airflow is sent out obliquely upward and obliquely downward, the possibility that the outlet airflow sent out from the indoor air outlet 13 is directly sucked by the indoor air inlet 12 can be further reduced. Of course, in other embodiments, the extending direction of the air outlet duct 17 may also be perpendicular to the front surface 14 of the inner casing.
In one embodiment, the two indoor outlets 13 are spaced in the vertical direction. So set up, can carry out the air-out according to heat transfer mode reasonable selection indoor air outlet 13 to reach better air supply effect, promote indoor heat transfer effect. For example, in the heating mode, since the hot air flow flows upward after being sent out from the indoor air outlet 13, the air can be sent out through the indoor air outlet 13 below, so that the hot air flow is sent out downward as much as possible, and the hot air flow can be better distributed indoors. In the cooling mode, the cold airflow is sent out from the indoor air outlet 13 and then flows downwards, so that the air can be supplied through the indoor air outlet 13 above, and the cold airflow is sent out upwards as much as possible, so that the cold airflow can be better distributed indoors. And two indoor air outlets 13 are arranged on the front surface 14 of the inner shell, so that the air supply range in the left and right directions is larger while the air supply range in the up and down directions is enlarged. Of course, in other embodiments, the two indoor air outlets 13 may be distributed at intervals in the left-right direction. Or the two indoor air outlets 13 are respectively arranged on the two inner shell side surfaces 15.
In one embodiment, the axial flow wind wheel 22 and the cross flow wind wheel 21 are arranged at intervals in the vertical direction. That is, the axial flow wind wheel 22 and the cross flow wind wheel 21 are arranged in the up-down direction, so that the size of the internal machine casing 10 in the left-right direction and the front-back direction can be reduced, and the indoor occupied area of the internal machine casing 10 can be reduced. But also the upper indoor air outlet 13 is at a higher position, so that the cold air flow can be sent to a higher position in the room in the cooling mode. Of course, in other embodiments, the axial flow wind wheel 22 and the cross flow wind wheel 21 may be arranged at a distance in the left-right direction.
The tubular wind wheel 21 and the axial wind wheel 22 are disposed in various ways in the inner machine casing 10, for example, in an embodiment, the axial wind wheel 22 is spaced below the tubular wind wheel 21. That is, the cross-flow wind wheel 21 is arranged above the axial-flow wind wheel 22, so that in the cooling mode, main air supply can be performed through the cross-flow wind wheel 21 to ensure the uniformity of sending out the cold air flow. In the heating mode, the axial flow wind wheel 22 can be used for mainly supplying air to ensure that the air volume of hot air flow is larger and indoor rapid heating is realized.
In one embodiment, the axial flow wind wheel 22 is spaced above the cross flow wind wheel 21. That is, the cross flow wind wheel 21 is arranged below the axial flow wind wheel 22, so that main air supply can be performed through the axial flow wind wheel 22 in a refrigeration mode, the air quantity of cold air flow is large, and indoor rapid cooling is achieved. In the heating mode, the main air supply can be carried out through the cross flow wind wheel 21 so as to ensure the uniformity of hot air flow.
In one embodiment, one indoor air inlet 12 is provided, and the air inlet sides of the cross flow wind wheel 21 and the axial flow wind wheel 22 are both communicated with the indoor air inlet 12. That is, the air inlet side of the cross flow wind wheel 21 and the air inlet side of the axial flow wind wheel 22 share one indoor air inlet 12, so that the number of the indoor air inlets 12 on the inner machine shell 10 is reduced, the structure of the inner machine shell 10 is simplified, and the production cost is reduced. Of course, in other embodiments, an indoor air inlet 12 may be provided on the inner machine casing 10 corresponding to each of the cross-flow wind wheel 21 and the axial-flow wind wheel 22.
Further, in an embodiment, the unitary air conditioner further includes an indoor heat exchanger 30, and the indoor heat exchanger 30 is disposed at the indoor air inlet 12. That is, the indoor side heat exchanger 30 is disposed inside the indoor air inlet 12, after the indoor air enters the indoor air duct 11 from the indoor air inlet 12, the indoor air firstly exchanges heat through the indoor side heat exchanger 30, and the air after heat exchange is respectively sucked by the cross flow wind wheel 21 and the axial flow wind wheel 22 and is respectively sent out by the cross flow wind wheel 21 and the axial flow wind wheel 22. Therefore, the cross flow wind wheel 21 and the axial flow wind wheel 22 share one indoor side heat exchanger 30, the number of the indoor side heat exchangers 30 can be reduced, the assembling procedures of the indoor side heat exchangers 30 are also reduced, and the production cost is reduced. Of course, in other embodiments, the indoor heat exchanger 30 may be disposed at the indoor air outlet 13. Or the air inlet sides of the cross flow wind wheel 21 and the axial flow wind wheel 22 are respectively provided with an indoor side heat exchanger 30.
In the embodiment that the air inlet side of the cross flow wind wheel 21 and the air inlet side of the axial flow wind wheel 22 are both communicated with the indoor air inlet 12, the air inlet side of the cross flow wind wheel 21 and the air inlet side of the axial flow wind wheel 22 are both arranged towards the indoor air inlet 12. That is, when the indoor heat exchanger 30 is disposed at the indoor air inlet 12, the air inlet side of the cross flow wind wheel 21 and the air inlet side of the axial flow wind wheel 22 both face the inner side surface of the indoor heat exchanger 30.
Referring to fig. 4, in an embodiment, the indoor air duct 11 includes a first air duct 111 and a second air duct 112 that are independent from each other, one of the indoor air outlets 13 is communicated with the first air duct 111, the other indoor air outlet 13 is communicated with the second air duct 112, the indoor air inlet 12 includes a first air inlet 121 communicated with the first air duct 111 and a second air inlet 122 communicated with the second air duct 112, the axial flow wind wheel 22 is disposed in the first air duct 111, and the cross flow wind wheel 21 is disposed in the second air duct 112. Therefore, the axial flow wind wheel 22 and the cross flow wind wheel 21 can be ensured to be mutually independent, so that the intake airflows of the axial flow wind wheel 22 and the cross flow wind wheel 21 are ensured to be mutually independent in the inner machine shell 10, and the condition that the suction airflow of one wind wheel (the axial flow wind wheel 22 or the cross flow wind wheel 21) is reduced due to overlarge negative pressure generated by the other wind wheel is avoided. Therefore, the air outlet speeds of the axial flow wind wheel 22 and the cross flow wind wheel 21 can be conveniently and independently adjusted, air supply with different speeds and different air volumes can be simultaneously realized for two different areas, various air outlet modes can be realized, and different air supply requirements can be met. The indoor air outlet 13 of the first air duct 111 and the indoor air outlet 13 of the second air duct 112 may be both disposed on the front surface 14 of the inner shell, or may be both disposed on the same side surface 15 (see fig. 1) of the inner shell, or the indoor air outlet 13 of the first air duct 111 and the indoor air outlet 13 of the second air duct 112 are respectively disposed on the two side surfaces 15 of the inner shell, or the indoor air outlet 13 of the first air duct 111 (the second air duct 112) is disposed on the front surface 14 of the inner shell, and the indoor air outlet 13 of the second air duct 112 (the first air duct 111) is disposed on the side surface 15 of the inner shell.
