The specific embodiment
Below in conjunction with drawings and Examples, the specific embodiment of the present utility model is described in further detail.Following examples are used to illustrate the utility model, but are not used for limiting scope of the present utility model.
As depicted in figs. 1 and 2, air-conditioner of the present utility model is made up of indoor set 10, front panel 14, front door 16, indoor set 10 front upper are provided with air outlet 12, the bottom of two sides and bottom are provided with air inlet 13, front panel 14 constitutes the previous section of indoor set 10, and is equiped with the slidable panels 15 that opens and closes air outlet 12.
Slide and be provided with the slidable panels 15 that can cover air outlet 12 in the front of described indoor set 10, air-conditioner is under running status and state out of service, described slidable panels descends or rises along straight line by mechanical driving device, thereby finishes the unlatching (see figure 2) in air outlet 12 fronts and close (see figure 1).Frame is provided with guide rail 21 in the indoor set 10, and slidable panels 15 back sides are provided with directive wheel 22, and described directive wheel 22 slides in guide rail 21.Described guide rail 21 bottoms are to described framework inner recess, the top of described guide rail 21 is the displacement of at least one front panel 15 thickness of displacement forward, be connected smoothly between described guide rail 21 tops and the guide rail bottom, make that slidable panels 15 rising backs and described front panel 14 are in the same plane.Shown in Figure 4 as Fig. 3 and partial enlarged drawing thereof.
Described guide rail 21 is provided with A limit switch 23, B limit switch 24, described stepper motor 17 receives and is rotated in the forward signal after the air-conditioner start, described stepper motor 17 drives slidable panels 15 by gear train, worm screw 19, tooth bar 20 transmissions and descends, when described directive wheel 22 touches A limit switch 24, described stepper motor 17 stops to be rotated in the forward, and described slidable panels 15 stops to descend.Described stepper motor 17 receives the reverse rotation signal after described air-conditioner shutdown, described stepper motor 17 drives slidable panels 15 by gear train, worm screw 19, tooth bar 20 transmissions and rises, when described directive wheel 22 touches B limit switch 23, described stepper motor 17 stops reverse rotation, and described slidable panels 15 stops to rise.
Figure 5 shows that the transmission device schematic diagram of the utility model air-conditioner slidable panels.Stepper motor 17 drive gear set, this gear train comprise three different gears 18, described gear set drive worm screw 19 with the tooth bar 20 of worm engaging on motion, rise or descend thereby drive slidable panels 15.Described gear train and stepper motor 17 are arranged on the frame at front panel 14 rear portions.The utility model is selected the directly kind of drive simple in structure of motion on tooth bar 20 of worm screw 19, can guarantee under the transmission stabilized uniform prerequisite, reduces transmission loss, reduces cost.
Below the action of the utility model slidable panels 15 is introduced.
When the air-conditioner in the utility model is worked, at first connect power supply, press shift knob, the control circuit output signal of telecommunication drives stepper motor and is rotated in the forward, under the driving of stepper motor, drive slidable panels 15 and descend, air outlet 12 is revealed by the worm rack transmission.After the directive wheel 22 at slidable panels 15 back sides is run into limit switch 24, the control circuit output signal of telecommunication drives stepper motor and stagnates rotation, press shift knob once more, the control circuit output signal of telecommunication drives the stepper motor reverse rotation, under the driving of stepper motor, drive slidable panels 15 and rise, air outlet 12 is closed by the worm rack transmission.After the directive wheel 22 at slidable panels 15 back sides was run into limit switch 23, the control circuit output signal of telecommunication drove stepper motor and stagnates rotation.
Air-conditioner provided by the utility model, when air-conditioner moved, worm gearing drove the decline of slidable panels, appears described air outlet; When air-conditioner was out of service, slidable panels can cover up air outlet under the drive of worm gearing dexterously, made that the front panel of air-conditioner was both attractive in appearance, can prevent that again dust or foreign matter from falling in the air outlet.Because the employing of simple worm gearing makes transmission loss reduce, transmission is stable.
The above only is a preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model know-why; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
