The first motor, the second motor, the 3rd motor, the 4th motor 63 and the 5th motor 64 are by controller control.
Further set forth the operation principle of the room air conditioner of the present embodiment below:
Figure 4 shows that the room air conditioner refrigerating operaton state space-time gas flow direction schematic diagram in the present embodiment, air-conditioner is in the time of refrigerating operaton state, the first through-flow fan blade 65 moves, the second through-flow fan blade 66 does not move, on opening and closing member 20, move and open the second auxiliary air inlet 11c, air intake thus, and the first auxiliary air inlet 11b is in closed condition; The first wind deflector 81 and the second wind deflector 82 are opened, by the second air port 12b air intake, and the first air port 12a air-out.Now air enters in air-conditioner from the second auxiliary air inlet 11c, the second air port 12b, after heat exchanger 30, by the first through-flow fan blade 65, by the first air port 12a blowing cold air.Cold wind is blown out by air-conditioner top, can more effectively lower the temperature to room.
Figure 5 shows that the room air conditioner heating operation state space-time gas flow direction schematic diagram in the present embodiment, air-conditioner is in the time of heating operation state, the first through-flow fan blade 65 does not move, the second through-flow fan blade 66 moves, opening and closing member 20 moves down opens the first auxiliary air inlet 11b, air intake thus, and the second auxiliary air inlet 11c is in closed condition; The first wind deflector 81, the second wind deflector 82 are opened, by the first air port 12a air intake, and the second air port 12b air-out.Now air enters in air-conditioner from the first auxiliary air inlet 11b, the first air port 12a, after auxiliary electric heater unit 40, by the second through-flow fan blade 66, blows out hot blast by the second air port 12b.Hot blast is blown out by air-conditioner below, can more effectively heat up to room.
As can be seen here, the room air conditioner refrigeration of the present embodiment, heating operation state, from diverse location air-out, can effectively improve air-conditioner comfortableness.Meanwhile, in the time that air-conditioner moves, only need the single through-flow fan blade of driving, another through-flow fan blade does not need to drive but still is rotatable, can be used for generating, expands other functions of air-conditioner.
Fig. 6 is to the structural representation that Figure 8 shows that the room air conditioner in another embodiment of the present invention, and the room air conditioner in the present embodiment is cabinet-type air conditioner.
The front view of the room air conditioner in Fig. 6 the present embodiment, Fig. 7 is the left side sectional view of the room air conditioner in the present embodiment, as can be seen from the figure, the each parts arrangement mode in the inside of the cabinet-type air conditioner in the present embodiment and hanging air conditioner are similar, but bottom increases support component 90.The first air port 12a is arranged between the front of housing 10 and end face on the 3rd inclined-plane, the second air port 12b is arranged at the positive bottom of housing 10, because the difference in height of cabinet-type air conditioner the first air port 12a and the second air port 12b is large compared with hanging air conditioner, remarkable compared with hanging air conditioner in the function that improves comfortableness, internal structure compactness simultaneously, compared with other cabinet-type air conditioners, its lateral thickness is less, take up an area space little, air-conditioner is got up from the side more fine.
Fig. 7 and Fig. 8 are respectively room air conditioner refrigerating operaton state and the heating operation state space-time gas flow direction schematic diagram in the present embodiment, under refrigerating operaton state and heating operation state, air is similar the flow direction of cabinet-type air conditioner inside and hanging air conditioner, but the heat exchanger 30 of cabinet-type air conditioner is larger, be that work area is large, can promote heat exchange amount and heat exchange efficiency, reduction noise.
The above embodiment has only expressed several embodiment of the present invention, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the scope of the claims of the present invention.It should be pointed out that for the person of ordinary skill of the art, without departing from the inventive concept of the premise, can also make some distortion and improvement, these all belong to protection scope of the present invention.Therefore, the protection domain of patent of the present invention should be as the criterion with claims.
