Fig. 3 is the utility model driving device structure schematic diagram.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is made detailed explanation.
The utility model provides a kind of pump type heat air conditioner indoor set, Fig. 1 and Fig. 2 are respectively the structural representation of this indoor set under refrigeration mode and heating mode, as shown in Figure 1 and Figure 2, be provided with heat exchanger 6 in the casing of indoor set, heat exchanger 6 is provided with electric heating tube 7, the below of heat exchanger 6 is provided with fan 5, the upper and lower of indoor set casing front panel 1 is respectively equipped with air outlet 11 and air inlet 12, under refrigeration mode, air enters from air inlet 12 by fan 5, and blows out from air outlet 11 after becoming cold wind through heat exchanger 6.
Be provided with auxiliary defrosting device and control module in the casing of indoor set, described auxiliary defrosting device comprises warming plate 2, this warming plate 2 is fixed in the casing and with air outlet on the front panel of indoor unit 1 11 and air inlet 12 to be separated, and forms from air inlet 12 air flow passage to air outlet 11.Be provided with one slide-plate 13 slidably on the inner surface of air outlet 11 belows of front panel of indoor unit, this slide plate 13 can seal or open air outlet 11 in the upper and lower slip of inner surface of the driving lower edge of drive unit 3 front panel of indoor unit 1.Warming plate 2 has a sidewall 21 that be arranged in parallel with slide plate 13, and the top of this sidewall 21 offers a window, and when this window was opened, air outlet 11 communicated with air inlet 12.Sliding on the sidewall 21 of warming plate 2 is provided with a cover plate 22, and cover plate 22 can be in the sidewall 21 upper and lower slips of the driving lower edge of drive unit 3 warming plate 2, open or closed side wall 21 on window.
The structure of drive unit 3 as shown in Figure 3, this drive unit 3 comprises motor 31, motor 31 is fixed in the gap of slide plate 13 and cover plate 22 formation, be fixed with first gear 33 on the output shaft of motor 31, be respectively equipped with first, second tooth bar 14,23 on slide plate 13 and the cover plate 22, first tooth bar 14 and 33 engagements of first gear are provided with second gear 32 and second gear 32 and mesh with second tooth bar 23 and first gear 33 respectively between second tooth bar 23 and first gear 33.
