First segmental arc 311 and/or second segmental arc 321 are moved vertically to stretching, extension or contraction.
It should be noted that the air outlet 101 includes multiple outlet air regions, each outlet air region corresponds to one group upper and lower
To in one first segmental arc 311 being correspondingly arranged and one second segmental arc 321, pass through the first segmental arc 311 and second of the group
Segmental arc 321 cooperates, thus it is possible to vary the wind direction in corresponding outlet air region.Since each drive component can be controlled individually
Corresponding first segmental arc 311 and second segmental arc 321 are made, therefore, the wind direction in multiple outlet air regions
Can be identical, it can not also be identical.Preferably, the quantity of first segmental arc 311 is 2~5, second segmental arc
321 quantity is 2~5.
In the present embodiment, each corresponding first segmental arc 311 of the driving component connection, with described in driving
First segmental arc 311 vertically to stretching, extension or is shunk.
With reference to Fig. 7 to Fig. 9, first segmental arc 311 is hollow structure, and it is gentle that the driving component includes air pump 400
Pipe 410, the tracheae 410 are equipped with air inlet and gas outlet 411, and first segmental arc 311 is equipped with and the gas outlet 411
The air inlet pipe 412 of connection, the air pump 400 are connected with the air inlet, to drive first segmental arc 311 vertically to stretching
Exhibition is shunk.It is to be appreciated that in order to preferably control first segmental arc 311 vertically to stretching, extension or the speed shunk
Degree can set dynamic clamping head and quiet clamping head, such as spring, silica gel etc. in first segmental arc 311.
Further, second segmental arc 321 is hollow structure, and second segmental arc 321 offers multiple ventilations
Hole 322.When air pump 400 is inflated by air inlet pipe 412 into the first segmental arc 311, the first segmental arc 311 can stretch downwards,
Meanwhile corresponding second segmental arc 321 is due to by the downward extruding force of the first segmental arc 311, in second segmental arc 321
Gas will flow out and retracted downward from the venthole 322.When air pump 400 takes out the first segmental arc 311 by tracheae 410
During gas, the first segmental arc 311 can be shunk upwards, meanwhile, corresponding second segmental arc 321 due to by the first segmental arc 311 to
On pulling force, which can stretch upwards.In this way, pass through the first segmental arc 311 and corresponding second arc
The mutual cooperation of section 321, thus it is possible to vary the shape of air outlet 101 changes wind direction.
With reference to Fig. 4 and Fig. 7, the driving component further includes crane 420, and the crane 420 is set on first arc
Between shape section 311 and corresponding second segmental arc 321, and connect first segmental arc 311 and second segmental arc
321。
In one embodiment, the driving component can be by controlling crane 420 to move up and down, and drives described first
311 and second segmental arc 321 of segmental arc vertically to stretching, extension or is shunk.Specifically, the driving component includes driving motor,
The driving motor connects the crane 420, the crane 420 to be driven to move up and down.Wherein, driving motor driving rises
There are many modes that drop frame 420 moves up and down, for example, driving motor can drive crane 420 to move up and down by transmission belt,
Crane 420 can also be driven to move up and down by way of rack and pinion engagement, can also be driven by cam mechanism
Crane 420 moves up and down, and does not do herein specifically limited.
When driving motor driving crane 420 moves up, the first pleat ring 310 is by the upward extruding of crane 420
Power and shrink upwards, meanwhile, the second pleat ring 320 is stretched upwards by the upward pulling force of crane 420；When driving motor drives
When crane 420 moves down, the first pleat ring 310 is stretched downwards by the downward pulling force of crane 420, meanwhile, the second pleat
The retracted downward by the downward extruding force of crane 420 of ring 320.
With continued reference to Fig. 7, the ceiling machine, which further includes, to be installed between the drip tray 200 and the air-inlet grille 130
Limiting plate 430, the limiting plate 430 offered vertically to the sliding slot of extension 431, and the crane 420 is equipped with lead
421, the lead 421 is slidably mounted in the sliding slot 431.It is to be appreciated that the effect of the sliding slot 431 is can be right
The crane 420 plays guiding role.Preferably, the both ends of the crane 420 are equipped with limiting plate 430.
Further, with reference to Fig. 2, Fig. 3 and Fig. 4, the panel assembly 100 further includes installing frame 140, the installing frame
140 are set to the inside of the flexible air duct 300.The effect of the installing frame is flexible air duct 300 can be played admittedly
It is set for using, can also play the role of keeping out the wind, prevent the gas of air inlet from flowing directly into air outlet across flexible air duct 300
101。
It is to be appreciated that in another embodiment, the driving device can also connect the first pleat ring 310, with driving
The first pleat ring 310 vertically to stretching, extension or is shunk.Wherein, driving device drives the first pleat ring 310 vertically to stretching, extension
Or the mode shunk, with reference to above-described embodiment, details are not described herein.
During using the utility model ceiling machine, stretched about 320 by driving the first pleat ring 310 and the second pleat ring, to change
Become the shape of air outlet 101, change wind direction, it is specific as follows：
Reference Fig. 3, when crane 420 is moved to first position, the shape invariance of the air outlet 101, at this point it is possible to
Form longer relatively stable air outlet 101, thus, the gas after heat exchanger heat exchange can be sent to farther out away from
From.
With reference to Fig. 5, when crane 420 is moved to the second position, the air outlet 101 is in widened shape after first reducing
Shape can realize the air-supply of polarizers of big angle scope in this way.Specifically, the gas after heat exchanger heat exchange, in the air outlet 101
Diminution position increase wind speed, the expansion position of the air outlet 101 increase blowing range, so as to fulfill sending for polarizers of big angle scope
Wind.
With reference to Fig. 6, when crane 420 is moved to the third place, the air outlet 101 is in the shape for first expanding and reducing afterwards
Shape, the in this way gas after heat exchanger heat exchange can be formed in the air outlet 101 and be buffered, so as to realize level angle
Balanced ventilation, improve the comfort level of user.
The above is only the preferred embodiment of the present invention, and it does not limit the scope of the patent of the present invention,
It is every under the inventive concept of the utility model, equivalent structure made based on the specification and figures of the utility model becomes
It changes or directly/is used in other related technical areas indirectly and is included in the scope of patent protection of the utility model.
