Detailed description of the invention
With specific embodiment, the present invention is described in further detail below in conjunction with the accompanying drawings, but not as the limit to the present invention
Fixed.
Air-conditioning device in the present invention, particularly a kind of wall-hanging air conditioning apparatus, it can use not according to different demands
Same air supply mode, thus enrich the air supply mode of wall-hanging air conditioner indoor unit, reach wall-hanging air conditioner refrigeration, heat work
The purpose of comfortable air-supply under condition.
As shown in Figures 1 to 5, the air-conditioning device in the present invention includes base 1, drive mechanism and wind-blocking mechanism 2, wherein,
Wind-blocking mechanism 2 respect thereto 1 is pivotably mounted, and such as, base 1 and wind-blocking mechanism 2 all can use the structure of circle, and keep out the wind machine
Structure 2 is placed in base 1 interiorly or exteriorly.
Offer multiple first air outlet 3 at base 1, correspondingly, wind-blocking mechanism 2 is then offered multiple second air outlet
4, wherein, the second air outlet 4 forms an air-out passage when overlapping with the first air outlet 3 together with the first air outlet 3.Cause
This, have and how many be the first overlapping air outlet 3 mutually and the second air outlet 4 then can form multiple few air-out passage.
More specifically, the number of the first air outlet 3 is more than the number of the second air outlet 4, so, when drive mechanism drives
When wind-blocking mechanism 2 respect thereto 1 moves, can form one group of air-out passage in different positions, wherein, one group of air-out passage can
To include one or more above-mentioned air-out passage.
Therefore, the present invention may utilize drive mechanism to drive wind-blocking mechanism 2, so that the second air outlet thereon moves, from
And after aliging in different positions, form air-out passage with corresponding first air outlet, thus change the position of air-out passage
(such as, angle or direction etc.), such that it is able to be adapted to freeze and heat the demand waited under different operating modes difference air-out modes,
Solve that wall-hanging air conditioner air-out of the prior art is single, heat the problem that comfortableness is bad.
Additionally, due to wind-blocking mechanism 2 can move back and forth under the driving of drive mechanism, therefore, available keep out the wind
This motion of mechanism 2 realizes sweeping the function of wind.
In the embodiment shown in Fig. 1 to Fig. 5, base 1 and wind-blocking mechanism 2 are the most rounded, the plurality of first air outlet 3
Can circumferentially distributed along base 1, the plurality of second air outlet 4 then circumferentially distributed, in the circumference of the two along wind-blocking mechanism 2
Angle corresponding, thus available drive mechanism makes wind-blocking mechanism 2 rotate, and with in rotary course, forms different angle
The air-out passage of degree, such as, by rotating the air-out passage that all can form special angle in the range of 360 degree, thus
Significantly meet the diversity requirement to air-out passage.
In order to preferably guide air-out direction, the present invention preferably can be mounted in each second air outlet 4
Deflector 5, such as, deflector 5 in the illustrated embodiment have employed multiple deflector be arrangeding in parallel, these deflectors
The water conservancy diversion shape of straight line or arc line type can be used.
Wind-blocking mechanism 2 can be ring-type in one, wherein has cavity, and the air-conditioning device in the present invention utilizes and is arranged on this chamber
Internal fan blade 6, outwards sends wind from air-out passage.In one embodiment, the air inlet in the present invention comes from and keeps out the wind
Mechanism 2 axial, centrifugal blower fan system then substantially along radially, is creatively applied to by its air-out passage for this present invention
In wall-hanging air conditioner indoor unit, fan blade 6 therein uses centrifugation blade.As it is shown in figure 1, the present invention also can be at the center of base 1
Place installs one for the blade driving motor 7 driving fan blade 6.So, it is connected with centrifugation blade at blade driving motor 7, and
Drive it to rotate, thus realize the purpose of air inlet through hollow shaft, radially air-out.
In one embodiment, the drive mechanism in the present invention uses rim gear wheel mechanism, nibbles with ring gear 8 including ring gear 8
The gear 9 closed and the gear drive motor being used for driving gear 9.Wherein, ring gear 8 is arranged on base 1, gear 9 and gear
Motor is driven then to be installed on wind-blocking mechanism 2.When gear drive motor drives gear 9 to rotate, due to gear 9 and ring gear 8
External tooth engagement, therefore, just drive wind-blocking mechanism 2 to rotate.Certainly, ring gear 8 can also use the structure of internal gear, falls within this
The equivalent way of invention.
Preferably, air-conditioning device also includes cover plate 10, forms one and be preferably square through hole, to install heat exchange in the middle part of it
Device 11.During installation, cover plate 10 is connected with base 1, thus forms one between cover plate 10 and base 1 and can be used for installation and keep out the wind machine
Structure 2 and the installing space of fan blade 6.Further, present invention additionally comprises heat exchanger 11, it is above-mentioned logical that it is arranged in the middle part of cover plate 10
In hole.During work, by the effect of fan blade 6, air-flow, along when axially sucking of wind-blocking mechanism 2, flows through heat exchanger 11, thus and its
There is heat exchange, then discharge from air-out passage.
As it is shown in figure 1, present invention additionally comprises air inlet faceplate 12, it is arranged on the side away from base 1 of cover plate 10, ascends the throne
Inlet side in heat exchanger 11.
Refer to Fig. 4 and Fig. 5, in a preferred embodiment, the present invention forms four the first air outlets 3 on base 1,
Meanwhile, on wind-blocking mechanism 2, three the second air outlets 4 are also formed.In addition to quantitative difference, in this embodiment, first
Air outlet 3 is the most corresponding with the second air outlet 4 position in the circumferential.It is highly preferred that these four the first air outlets 3 are along base 1
Circumference be uniformly distributed so that the angle between adjacent two the first air outlets 3 is 90 degree.Correspondingly, above three second goes out
The position in air port 4 is the most corresponding with the position of three in aforementioned four the first air outlet 3.So, during rotation, can simultaneously shape
Become three air-out passages.
Refer to Fig. 4 and Fig. 5, the air-out of centrifugation blade is guided by deflector 5, thus the air-out of annular is guided
Form three strands of air-flows concentrated, reach to increase the purpose of wind velocity.Wind-blocking mechanism 2 in the present invention is carried out by drive mechanism
Rotate, thus change the angle of air-out.Wherein, Fig. 4 shows air outlet angle during heating condition, when wind-blocking mechanism 2 rotate to
During position shown in Fig. 4, under formation, left and right three air outlets, heating air port the nearest, thermal current is easier to land reality
Now heat the function that foot is warm.Fig. 5 then shows air outlet angle during refrigeration die worker's condition, and now wind-blocking mechanism rotates to shown in Fig. 5
State, thus form upper, left and right three air outlets, owing to refrigeration air port is in higher position at this moment, cold airflow is from room
Between top cover and realize refrigeration head and want cool function.Additionally, be also with rotating back and forth of wind-blocking mechanism, it is achieved sweep wind merit
Energy.
Certainly, it is above the preferred embodiment of the present invention.It should be pointed out that, for those skilled in the art
For, on the premise of without departing from its general principles, it is also possible to make some improvements and modifications, these improvements and modifications are also
It is considered as protection scope of the present invention.
