The specific embodiment
Embodiment 1:
Structural representation of the present invention as shown in Figure 1, cleaning apparatus for self 1 is placed on the air inlet front side of air conditioner room unit air-duct spiral case 2, the screen pack in the device can rotate around air-duct spiral case air inlet center in the space between air-duct spiral case and the air intake barrier.In the air-conditioner running, air sucks air-duct spiral case through the cleaning apparatus for self screen pack by blower fan, again through the heat exchanger after-blow to indoor, and that dust in air is attracted to air filtration is online.After operation a period of time, the dust on the screen pack can be absorbed and be discharged from outdoor by cleaning apparatus for self.
Fig. 2 is the section construction figure of cleaning apparatus for self, whole device is made of three parts, and the one, 4, one of suction nozzle bodies are the screen pack mechanisms that screen pack 3 and support thereof etc. are constituted, another dust collection mechanism does not show that in the drawings suction nozzle body 4 links to each other with dust collection mechanism by a sweep-up pipe.
Fig. 3 is the schematic diagram of embodiment.This programme changes the shape and the arrangement of traditional screen pack, and screen pack is designed to revolving structure, and screen pack and support body thereof can rotate around a certain center line, and suction nozzle body keeps quiet state.The suction port 5 that suction nozzle body 4 lower ends are provided with is rectangular slit, it contacts with screen pack 3, suction nozzle body 4 links to each other with dust collection mechanism, dust suction pump in the dust collection mechanism produces the negative pressure high velocity air in the vacuum chamber of suction nozzle body 4, suction port 5 places keep strong dust-absorbing strength, screen pack 3 contacts laying dust partly just by dust suction slit suction vacuum chamber with slit, discharge outdoor by dust collection mechanism again.Screen pack 3 is low speed rotation under the driving of drive system, can switch the contact area of suction port 5 and screen pack 3 in turn, when screen pack rotates a week, then finish a cleaning stroke of whole screen pack, clean for guaranteeing the screen pack cleaning, can set the rotation time that cleans the task screen pack each time.The height H of screen pack mechanism also can be adjusted according to the appearance and size of whole air-conditioner simultaneously.
Fig. 4 is the suction nozzle body of this device and the structure explosive view of screen pack mechanism, and wherein screen pack mechanism mainly is made up of base 6, gear drive circle 7, pressure net circle 8, filter screen bracket 11, screen pack 3, pinion 12 and motor 13.Suction nozzle body is made up of suction nozzle support 9 and suction nozzle 10.Base 6 in the screen pack mechanism is fixed on the air-duct spiral case as the main support parts, gear drive circle 7, filter screen bracket 11, screen pack 3 and press net circle 8 rotatable parts that constituted to rotate under the drive systems that pinion 12 and motor 13 are formed.Suction nozzle support 9 is fixed on the base, and there is strip dust suction slit 5 suction nozzle support lower end, and suction nozzle 10 is fixed on the suction nozzle support, and suction nozzle 10 links to each other with the dust collection mechanism of being made up of dust suction pump and dust flue by sweep-up pipe.When the cleaning action took place, suction nozzle body maintained static, and the pivoting part that has only gear drive circle 7, filter screen bracket 11, screen pack 3 and press net circle 8 to form rotates.
Fig. 5 and Fig. 6 are the structural representation of suction nozzle body, and as shown in Figure 5, suction nozzle support 9 has only half zone that the dust suction slit is arranged, and plays the dust suction effect, and second half is as rigidity and the intensity of holder part to guarantee whole suction nozzle body.If the dust suction slit designs on whole suction nozzle support, then requires the power output of dust collection mechanism to increase, its appearance and size also can correspondingly strengthen.Fig. 5 also shows the cross-sectional view of suction nozzle support 9 vacuum parts, and as can be seen, suction nozzle support 9 and suction nozzle form the dust suction cavity between the two by seal felt 14 sealings.There is suction port 5 suction nozzle support 9 lower ends, and suction port 5 peripheral edge portions are outstanding to the contact direction of screen pack 3, and ledge can guarantee that suction port 5 contacts with screen pack 3 well, and the dust on the screen pack 3 only needs very little dust-absorbing strength to absorb.
Cross-sectional view shows that the vacuum part design of suction nozzle support is fluted among Fig. 5, and the bottom of groove offers suction port 5, and as shown in Figure 6, suction port 5 is made up of a series of strip finedraw 5a, 5b, 5c.
Fig. 7～Figure 12 is the structure and the motion mode of explanation screen pack mechanism part.As mentioned above, screen pack mechanism is made up of base 6, rotating part and drive part.Drive part is made up of motor 13 and pinion 12, as shown in Figure 8.Motor 13 is fixed on the base 6, the output shaft of motor 13 and pinion 12 closely cooperate, design has a circle gear on the gear drive circle 7, but pinion 12 driven gear transmission circles 7 are done the low speed gyration in the groove of base 6, and the filter screen bracket 11, screen pack and the pressure net circle (not shown) that are fixed on the gear drive circle 7 are also rotated thereupon.
In fact, can be easy to the rotating speed of controlled filter net rotating part by the number of teeth of adjusting gear, generally speaking, we need lower rotating speed, the a certain zone that can guarantee dust suction slit and screen pack like this is longer time of contact, has adequate time to finish this regional dust suction task.
Fig. 9 and Figure 10 have shown the modes of emplacement of gear drive circle 7 at base 6, gear drive circle 7 is placed in the groove of base 6, the edge designs of base 6 has some trips 16, and the effect of trip 16 is to prevent that gear drive circle 7 from bob taking place produce bumpy motion and noise in rotation process.Trip 16 does not closely contact with the upper surface of gear drive circle 7, but needs to keep certain clearance, causes the gear drive circle may produce " stuck " phenomenon to prevent friction each other.
In order to guarantee 7 motions of gear drive circle steadily, prevent that particularly gear drive circle 7 from producing bigger radial-play in rotation process, also designed limiting tooth 17, as shown in figure 10 in the groove of base 6.Limiting tooth 17 in base 6 grooves is the discontinuous spacing preiections of a circle, as 17a, 17b, 17c, 17d ... one side of spacing preiection and the outside end portion of gear drive circle 7 keep non-tight contact condition, and it is to reduce the frictional force of gear drive circle 7 under issuable contact condition that these spacing preiections are designed to tooth type structures.
Among Figure 11, filter screen bracket 11 rotates with the gear drive circle, relative slip can not be arranged each other or beat, therefore design on the filter screen bracket 11 have some rack trips 18 and rack fixedly inserted link 19 it is fixed on the gear drive circle 7.Designed fixedly inserted link 19 of some rack trips 18 and rack in the contact site of filter screen bracket 11 lower ends and gear drive circle, rack trip and rack fixedly inserted link are alternately distributed around the rack lower end.Correspondingly, also offer fixedly inserted link groove 21 of the rack trip groove 20 of respective number and rack in the contact site of gear drive circle 7 upper ends and filter screen bracket 11.Rack trip groove and rack fixedly inserted link groove also are alternately distributed position, upper end at gear drive circle 7.Wherein rack trip 18 is that pine contacts with trip groove 20, prevents that filter screen bracket 11 breaks away from gear drive circle 7 or bob takes place in running.Rack fixedly inserted link 19 and rack fixedly inserted link groove 21 are close contact, prevent that filter screen bracket from producing radially or circumferential play in running.
Figure 12 has shown the rigging position of pressing net circle 8 and screen pack 3.Airstrainer 3 posts on filter screen bracket 11 by the mode of mold pressing.Press net circle 8 to be close to the filter screen bracket peripheral edge portion, its effect is to prevent that the screen pack marginal portion from coming off, and guarantees good looking appearance.
Embodiment 2:
Structure of the present invention is identical with embodiment 1, difference is the difference of suction nozzle body, Figure 13 is the structural representation of suction nozzle body, suction port 5 configurations in suction nozzle body upper edge sweep dirt hairbrush 22, sweep dirt hairbrush 22 and use the softer fine, soft fur of quality, closely contact with airstrainer, for the laying dust that suction nozzle can't thoroughly be absorbed, can be by sweeping 22 cleanings of dirt hairbrush.The mode that this subsidiary hairbrush is swept dirt is at first absorbed the dust on the screen pack by the suction port on the suction nozzle support, the difficult laying dust of absorbing then can be brushed from behind by sweeping the dirt hairbrush, can improve the dust removing effects of whole device like this.
Embodiment 3:
Structure of the present invention is identical with embodiment 1, difference is the difference of cleaning apparatus for self 1, the cleaning apparatus for self that has shown another kind of structure among Figure 14 and Figure 15, in this embodiment, the all more above-mentioned embodiment of the profile of filter screen bracket and suction nozzle has had bigger variation, filter screen bracket 11 adopts the form of dome, and promptly cross section is an arch.Correspondingly, suction nozzle 10 also is designed to the domes of suitable radian, so that suction port 5 closely contacts with airstrainer 3.The same with embodiment 1, suction nozzle body is motionless, and screen pack rotates together in company with rack.
Embodiment 4:
Structure of the present invention is identical with embodiment 1, and difference is the difference of suction nozzle body, and Figure 16 and Figure 17 are the structural representations of suction nozzle body, promptly adopts many suction nozzle bodies to finish the dust suction action.Shown in Figure 16 is the suction nozzle body that is provided with two suction nozzle 10a and 10b, correspondingly, the corresponding one section dust suction slit of each suction nozzle, each suction nozzle is all linked to each other with dust collection mechanism by sweep-up pipe.Certainly the number of suction nozzle can be at two or more according to the actual needs.
This many suction nozzles dust suction mode reduces the length of dust suction slit, and the dust suction area also reduces with regard to corresponding, and required dust-absorbing strength just significantly reduces, so the power output of dust suction pump significantly reduces in the dust collection mechanism, and the appearance and size of whole device is miniaturization more also.
In many suction nozzle bodies, the corresponding dust suction zone of each suction nozzle.Many suction nozzles mode both can adopt the dust suction of a plurality of dust suction pump, also can adopt the dust suction of single dust suction pump.
Each suction nozzle is continuous with corresponding dust suction pump by sweep-up pipe in many dust suctions pump mode, and in this mode, the cleaning in zone separately of finishing that each suction nozzle can be separate is moved, and shortened the cleaning time greatly, but the cost of this mode is higher.
A plurality of suction nozzles are concentrated by sweep-up pipe and are connected on the special attaching parts in the single suction dirt pump mode, attaching parts are connected with a dust suction pump again, in the cleaning process, have only a suction nozzle to be communicated with and produce dust suction and move with the dust suction pump, other suction nozzles then can not be worked, finish the cleaning task of region when this suction nozzle after, attaching parts make the dust suction pump be communicated with another suction nozzle, finish the cleaning task in new zone, change the connected state of dust suction pump and suction nozzle so successively, can clean the dust in the whole zone of screen pack.This mode is compared with preceding a kind of mode, and the cleaning time increases, and single needs a dust suction pump.
In fact laying dust degree varies sample on the screen pack, the required dust-absorbing strength of the suction nozzle of region is also different, the power output of the dust suction pump of each corresponding suction nozzle can be adjusted according to actual needs, so just can reduce the waste of dust suction pump power, this also is another characteristics of many suction nozzle bodies.
