Specific embodiment
To make the above purposes, features and advantages of the invention more obvious and understandable, with reference to the accompanying drawing to the present invention
Specific embodiment be described in detail.
As shown in Figure 1, being a kind of indoor unit that a variety of air-out modes can be achieved provided by the invention, the indoor unit is to hang
Machine.The indoor unit includes shell, and the shell is equipped with the lower air port 12 positioned at the uptake 11 at top and positioned at bottom, institute
The first wind deflector 21 of setting at uptake 11 is stated, second wind deflector 22 is set at the lower air port 12；It is equipped with and leans in the shell
The first fan blade 31 at the nearly uptake, the second fan blade 32 at the lower air port.
Preferably, first fan blade 31 and the second fan blade 32 are through-flow fan blade, mainly since through-flow fan blade can be
In the case that air duct is shorter, realize that air inlet and the outlet are more smooth.
Preferably, it is formed on the shell close to the first auxiliary air port 13 of the uptake 11 and close to the leeward
Second auxiliary air port 14 of mouth 12, first auxiliary are equipped with third wind deflector 23 at air port 13, and the third wind deflector 23 is beaten
It is located at 13 inside of the first auxiliary air port after opening, second auxiliary is equipped with the 4th wind deflector 24, the 4th wind-guiding at air port 14
Plate 24 is located at 14 inside of the second auxiliary air port after opening, setting in this way can guarantee that third wind deflector 23 and the 4th wind deflector 24 are beaten
Uptake 11 and lower 12 air inlet/outlet of air port are not influenced after opening.By the setting in the first auxiliary air port and the second auxiliary air port, can increase
The intake of big indoor unit.
Preferably, the position in air port is assisted to meet the air inlet of first auxiliary air port (13) without the first fan blade
(31), the air inlet of second auxiliary air port (14) is without the second fan blade (32), in this way, not needed by auxiliary air port air inlet
By the setting of its close fan blade, the windage of its air inlet is reduced, intake can be further increased, further increase air-conditioning
Refrigeration or heating efficiency.
Specifically, the air channel structure being connected to the first auxiliary air port 13 and the second auxiliary air port 14, can be achieved will be from this
The wind that auxiliary air port enters guides evaporator 50 into.
As shown in Fig. 2, the exit of the air channel structure in the first auxiliary air port 13 and second auxiliary air port 14
It is equipped with outlet section 15, the outlet section 15 is grid-like or cellular, preferably grid-like.By the setting of outlet section 15,
On the one hand it can prevent user from protruding into hand inside air conditioner, improve the safety of indoor unit, on the other hand, using different sizes
Hole can realize the filtering of air inlet, keep clean inside air conditioner.
Preferably, it is equipped with the first swing flap blade 41 at the uptake 11, is equipped with the second swing flap leaf at the lower air port 12
Lateral swing flap can be achieved in piece 42, the first swing flap blade 41 and the second swing flap blade 42, can increase swing flap range, further
Realization carries out control and regulation effect to air-out direction.
For the space utilization rate for reducing the volume of indoor on-hook as far as possible, improving indoor on-hook, it is preferable that the shell
It is inside provided with an evaporator 50, the evaporator 50 is between first fan blade 31 and second fan blade 32, therefore,
First fan blade 31 or second fan blade 32 can be operated according to actual needs, are bypassed air through evaporator 50 and are entered accordingly
Air duct, and then be discharged again from uptake 11 or lower air port 12.
The present invention provides a kind of control method of indoor unit, can realize a variety of air-out modes according to user demand, it is described go out
Wind mode includes at least one of normal refrigeration mode, conventional heating mode and cold wind not blow-through mode, specific as follows:
(1) it normal refrigeration mode: when user is big to refrigeration demand amount (such as just outside hot room to interior), can control
Indoor unit enters normal refrigeration mode；
As shown in figure 3, under normal refrigeration mode, first wind deflector 21, the second wind deflector 22 and third wind deflector
23 are in an open state, and the uptake 11 is air intake mode, and the lower air port 12 is air-out mode, first auxiliary air port 13
Auxiliary air inlet,；First fan blade 31 is inoperative, guarantees that air stream swimmingly can pass through evaporator 50 from the upper air inlet/outlet 11
After reach the second fan blade 32, the operating of the second fan blade 32 and air stream are from outlet air from the lower air port 12；
(2) heating mode: when user has heating needs, controllable indoor unit enters conventional heating mode；
As shown in figure 4, in a heating mode, first wind deflector 21, the second wind deflector 22 and third wind deflector 23 are
Opening state, the uptake 11 are air intake mode, and the lower air port 12 is air-out mode, and first auxiliary air port 13 assists
Air inlet；First fan blade 31 is inoperative, guarantee air stream can swimmingly from the upper air inlet/outlet 11 after evaporator 50 to
Up to the second fan blade 32, second fan blade 32 operating and air stream are from outlet air from the lower air port 12；Under the heating mode,
The angle that second wind deflector 22 is opened is bigger than the angle that it is opened under the normal refrigeration mode, and can be achieved in this way will be hot
Wind is blown towards ground as far as possible, is improved hot wind and is landed air quantity, realizes that blanket type send the effect of heat.
(3) it cold wind not blow-through mode: when user is not intended to cold wind blow-through and needs preferable refrigeration effect, can control
Indoor unit enters cold wind not blow-through mode；
As shown in figure 5, under cold wind not blow-through mode, and first wind deflector 21, the second wind deflector 22 and the 4th are led
Aerofoil 24 is in an open state, and the uptake 11 is air-out mode, and the lower air port 12 is air intake mode, the second auxiliary wind
14 auxiliary air inlets of mouth；Second fan blade 32 is inoperative, guarantees that air stream can be swimmingly from the lower air inlet/outlet 12 through pervaporation
The first fan blade 31, the operating of the first fan blade 31 and air stream are reached after device 50 from outlet air from the uptake 11；It in this way can be real
Cold wind is blown upwards now, realizes that shower formula send cold effect, and the cold wind blown out at the uptake 11 for being located at top is upward
It blows, will not really realize calm sense refrigeration towards human body completely.
The present invention also provides a kind of air conditioners comprising above-mentioned indoor unit.By double through-flow fan blade, double inlet and outlets and
The setting in double auxiliary air ports, air-flow court when air-flow being conveyed or be delivered up, heated downwards when can be realized control air conditioner refrigerating
It conveys downwards, meets the different demands of user in varied situations, improve the comfort of air conditioner air-supply.
Although present disclosure is as above, present invention is not limited to this.Anyone skilled in the art are not departing from this
It in the spirit and scope of invention, can make various changes or modifications, therefore protection scope of the present invention should be with claim institute
Subject to the range of restriction.
