Because the density of hot air is small, the density of cold air can naturally rise, and the density of cold air is large, the density of cold air can naturally sink. Therefore, in order to make the heating and refrigerating effect better, during heating, the transverse fan blades swing downwards to enable the air outlet direction to be downward, and the downward blowing hot air naturally rises after reaching the lowest point, so that the whole room is quickly heated. And on the contrary, the transverse fan blades swing upwards to enable the air outlet direction to be upward, and the upward-blown cold air naturally sinks after reaching the highest point, so that the delivery range of the cold air is enlarged.
However, since the lateral wind plate is high from the ground and the wind guiding distance is short, it is difficult to blow the wind near the ground when guiding the wind downward, and thus the heating effect of the indoor lower space is poor. If the wind speed is regulated to the maximum, the ground can be reached, but the air outlet is higher, and the air can be blown far down obliquely and then can fall to the ground, so that the heating effect near the air conditioner is poor.

as shown in fig. 6, when the baffle 5 is located at the first position, the baffle 5 may separate the air inlet 14 from the space 23 between the first heat exchange plate 21 and the second heat exchange plate 22;
as shown in fig. 8, when the baffle 5 is located at the second position, the baffle 5 may separate the space 24 outside the first heat exchange plate 21 and the second heat exchange plate 22 from the air inlet 14.
In the cabinet air conditioner provided by the embodiment of the invention, since the baffle plate 5 can move between the first position and the second position, when the end of the first heat exchange plate 21 and the second heat exchange plate 22, which are far away from each other, is upward, in the refrigeration state, as shown in fig. 6, the baffle plate 5 moves to the first position to separate the space 23 between the first heat exchange plate 21 and the second heat exchange plate 22 from the air inlet 14, and at this time, the flow path of the air flow is as shown in fig. 4: under the action of the first fan 3, the air enters the space 24 outside the first heat exchange plate body 21 and the second heat exchange plate body 22 from the air inlet 14, passes through the evaporator 2 upwards, and then is blown to the upper air outlet 15 and blown out. In the heating state, as shown in fig. 8, the baffle 5 moves to the second position to separate the space 24 outside the first heat exchange plate 21 and the second heat exchange plate 22 from the air inlet 14, and at this time, the flow path of the air flow is as shown in fig. 5: under the action of the second fan 4, the air enters a space 23 between the first heat exchange plate body 21 and the second heat exchange plate body 22 from the air inlet 14, passes through the evaporator 2 downwards, and then is blown to the lower air outlet 16 and is blown out. Thereby realizing the functions of upward air supply during refrigeration and downward air supply during heating, and improving the refrigeration effect. The structure can realize the switching of wind direction through the movement of a group of baffles 5, has simple structure and less parts, and can effectively save space and manufacturing cost.
It should be noted that, the space 24 outside the first heat exchange plate body 21 and the second heat exchange plate body 22 refers to a space 23 between the outer side surface of the first heat exchange plate body 21 and the inner wall of the middle air duct 12 opposite thereto, and a space 23 between the outer side surface of the second heat exchange plate body 22 and the inner wall of the middle air duct 12 opposite thereto, that is, the space 24 in fig. 4, respectively. The ends of the first heat exchange plate body 21 and the second heat exchange plate body 22 are close to each other, and the ends close to each other may be connected or not connected, and are not limited herein.
Wherein, the end of the first heat exchange plate 21 and the second heat exchange plate 22 away from each other may be disposed near the upper air duct 11 or near the lower air duct 13. When the ends of the first heat exchange plate body 21 and the second heat exchange plate body 22, which are far from each other, are close to the upper air duct 11, the space 23 between the first heat exchange plate body 21 and the second heat exchange plate body 22 is communicated with the upper air duct 11, and the space 24 outside the first heat exchange plate body 21 and the second heat exchange plate body 22 is communicated with the lower air duct 13. When the ends of the first heat exchange plate body 21 and the second heat exchange plate body 22, which are far from each other, are close to the lower air duct 13, the space 23 between the first heat exchange plate body 21 and the second heat exchange plate body 22 is communicated with the lower air duct 13, and the space 24 outside the first heat exchange plate body 21 and the second heat exchange plate body 22 is communicated with the upper air duct 11. For example, when the evaporator 2 is of a V-shaped configuration, the opening of the V-shaped configuration may be both upward and downward.
In order to facilitate the implementation of the above-mentioned scheme, specifically, as shown in fig. 6 and 8, the housing 1 corresponding to the middle air duct 12 may be made into a hollow structure, and the hollow hole of the hollow structure is used as the air inlet 14, so when the baffle 5 is located at the first position, as shown in fig. 6, the baffle 5 seals the hollow hole corresponding to the space 23 between the first heat exchange plate 21 and the second heat exchange plate 22, so that the hollow holes corresponding to the outer side surface of the first heat exchange plate 21 and the outer side surface of the second heat exchange plate 22 are opened; when the baffle 5 is located at the second position, as shown in fig. 8, the baffle 5 plugs the hollowed holes corresponding to the outer side surface of the first heat exchange plate 21 and the outer side surface of the second heat exchange plate 22, so that the hollowed holes corresponding to the space 23 between the first heat exchange plate 21 and the second heat exchange plate 22 are opened. Therefore, the switching between the connection and disconnection of each space divided by the middle air duct 12 and the air inlet 14 by the evaporator 2 is realized, and the structure is simple, fewer parts are adopted, and the realization is convenient.
It should be noted that, since the baffle 5 needs to plug the hollowed holes corresponding to the outer side surface of the first heat exchange plate 21 and the outer side surface of the second heat exchange plate 22, the baffle 5 may include two parts, namely, the first baffle part 51 and the second baffle part 52 in fig. 7 and 9. When the baffle 5 is located at the first position, as shown in fig. 6 and fig. 7, the first baffle portion 51 and the second baffle portion 52 respectively block the hollowed holes corresponding to the two ends of the space 23; when the baffle 5 is in the second position, as shown in fig. 8 and 9, the first baffle portion 51 seals the hollowed holes corresponding to the outer surface of the first heat exchange plate 21, and the second baffle portion 52 seals the hollowed holes corresponding to the outer surface of the second heat exchange plate 22.

The first baffle portion 51 and the second baffle portion 52 may be partially connected together or may be entirely separate. When the first barrier portion 51 and the second barrier portion 52 of the barrier 5 are of an integral structure, the barrier 5 can be driven by a set of barrier driving assemblies. When the first barrier portion 51 and the second barrier portion 52 are of a split structure, two sets of barrier driving assemblies may be provided to drive the first barrier portion 51 and the second barrier portion 52, respectively.
