In conjunction with Fig. 3 and shown in Figure 4, described driven unit groove 202 lower ends have front limit step 203, described front limit step 203 cooperates with the crank arm 524 of described crank 520, when being formed on described turn panel and outwarding winding described turn panel is carried out the front limit structure of front limit.
Fig. 5 shows the assembling stereogram of driven unit among Fig. 1, and Fig. 6 then shows the decomposing schematic representation of described driven unit.
In conjunction with Fig. 5 and shown in Figure 6, described driven unit 500 comprises motor 510, be arranged with the crank axle 521 of crank 520 on the motor shaft 512 of described motor 510, the other end of described crank axle 521 has elastic hook 522, the tie rod holes 531 of connecting rod 530 1 ends is set on the described elastic hook 522, and the tie rod holes 532 of described connecting rod 530 other ends is fixed on the described drop front 300 by bearing pin 540 and back-up ring 550.Have hook step 523 at the top of described elastic hook 522, be used to stop described tie rod holes 531 to withdraw from from described elastic hook 522.
The process of the unscrewing type panel in assembling the foregoing description is as follows:
The first step, assembling turn panel: described front shroud 400 is lumped together with described drop front 300, utilize screw and double-screw bolt that described front shroud 400 and described drop front 300 are tightened together then, form the turn panel.
Second step, assembling driven unit: the elastic hook 522 that the tie rod holes 531 of described connecting rod 530 1 ends is inserted in described crank 520, be close to up to the medial surface of described tie rod holes 531 and the lateral surface of described crank 520, this moment, elastic hook 522 outwards flicked, and the described tie rod holes 531 of described hook step 523 restrictions withdraws from; Crank axle 521 with described crank 520 is inserted on the motor shaft 512 of described motor 510 then.
In the 3rd step, driven unit is assembled on the fixed panel: the motor hole 511 that utilizes screw to pass described motor 510 is fixed on the screw post of described fixed panel 200, and motor is located fully; One end of described crank axle 521 is spacing by described motor 510, the other end of described crank axle 521 be inserted into realize in the crank axis hole 201 on the described fixed panel 200 spacing.
In the 4th step, assembling turn panel is to fixed panel: the rotating shaft 630 on the described drop front 300 is put into open slot 620 on the described fixed panel 200, and described rotating shaft 630 is embedded in the semilune groove 621 of described open slot 620 bottoms; Simultaneously, the left limit piece 730 on the described drop front 300 enters described narrow 722 from wide 721 of described left limit hole 720, and the right limit piece on the described drop front 300 enters described narrow 822 from wide 821 of described right limit hole 820.
The 5th step, assembling bearing pin and back-up ring: the pin shaft hole 301 with the tie rod holes 532 of described connecting rod 530 other ends is aimed on the described drop front 300, insert described bearing pin 540 then, load onto described back-up ring 550 at last, finish the assembling of whole unscrewing type panels.
And the unscrewing type panel process in dismounting the foregoing description is fairly simple, only need spur described turn panel towards the front upper place, and described rotating shaft 630 is deviate from from the opening part of described open slot 620, described connecting rod 530 is separated getting final product then with described crank 520.
Fig. 7 is a driven unit part disassembly process schematic diagram among Fig. 1.Wherein, Fig. 7-1 is connecting rod 530 and crank 520 assembled state schematic diagrames, and Fig. 7-2 is for depressing the schematic diagram of elastic hook 522, and Fig. 7-3 withdraws from the schematic diagram of elastic hook 522 for connecting rod 530; Fig. 7-4 is connecting rod 530 and schematic diagram after crank 520 separates.Described embodiment can take described connecting rod 530 apart easily, thereby be convenient to the unscrewing type panel is cleaned and keeps in repair by pushing described elastic hook 522 with described crank 520.
Fig. 8 is described for the stereogram of air-conditioner under unscrewing type panel closure state of unscrewing type panel among Fig. 1 is installed; Fig. 9 then is the stereogram of air-conditioner under the unscrewing type panel is outwarded winding state among Fig. 8.Described air-conditioner comprises main body 100, in described main body 100 fronts the unscrewing type panel of being made up of fixed panel 200, drop front 300 and front shroud 400 is installed.
Above-mentioned air-conditioner is when off working state, and described unscrewing type panel is in closure state.Under the effect of described driven unit 500 self-lock forces and described lower limit structure 600, described turn panel can forwards not move to producing with downward direction.Described turn panel is spacing following described left limit structure 700 and described right limit structure 800, can not produce direction and moving to right left.Described turn panel described upper limit structure 900 spacing down, can not produce upward to move.In addition, rub when avoiding described turn panel opening, between the confined planes 931 of the confined planes 921 of described fixed panel upper limit muscle 920 and described turn panel upper limit muscle 930, leave certain clearance.Because the cooperation intensity of described lower limit structure 600, described left limit structure 700, described right limit structure 800 and described upper limit structure 900 is bigger; can bear bigger impact and can not be out of shape or damage, can protect the weak driven unit 500 of intensity relative thin can not damage effectively.
When air-conditioner was opened, described motor 510 was just changeing, and drove described crank 520 and rotated, and described crank 520 drives described connecting rod 530 swings, opens around rotating shaft 630 thereby promote described turn panel by described bearing pin 540.Described rotating shaft 630 is subjected to described open slot 620 spacing in forward and backward, following three directions, can not move up by the self gravitation effect, and therefore, described turn panel rotates around described rotating shaft 630 all the time.Because the height of projection size of described left limit piece 730 and right limit piece is bigger, no matter when unscrewing type panel closure is still outwarded winding, described left limit piece 730 and 720 positions, described left limit hole and described right limit piece and 820 positions, described right limit hole all are in mated condition, played good guide effect, therefore, described turn panel can not produce moving of left and right directions.When described turn panel was outwarded winding needed maximum position, described crank arm 524 was collided with described front limit step 203, and described motor 510 stops operating, and air enters to air-conditioner from described ventilating opening 204.After air-conditioner receives shutdown signal, described motor 510 counter-rotatings, thus drive described turn panel closure.
Unscrewing type panel construction described in the utility model is simple, and running is steadily reliable, not fragile, processing, easy disassembling, and the scope of application is wider.
Certainly; the above only is a kind of 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 principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
