Detailed description of the invention
Below in conjunction with specific embodiment, the present invention is described in more detail.
Refer to Fig. 1 to Fig. 6, a kind of refrigerator MOD provided in figure, comprises MOD door frame 40, MOD door-plate 10, MOD sealing plate 20 and driving mechanism.
MOD door frame 40 is provided with an air door 41, and air door 41 is positioned at MOD door frame 40 roughly centre position, is provided with gear-box 42 on rear side of MOD door frame 40.The driving mechanism of this refrigerator MOD adopts damper motor (not shown) and gear assembly 50, and gear assembly 50 is arranged in gear-box 42, and gear-box 42 is provided with gear box cover 60.
MOD door-plate 10 is articulated with the latter of MOD door frame 40, is driven and overturn by gear assembly 50.MOD sealing plate 20 is placed on MOD door-plate 10 also fixing, and this MOD sealing plate 20 is driven by MOD door-plate 10 and realizes opening and closing the air door 41 on MOD door frame 40.
MOD sealing plate 20 is equipped with a current-limiting apparatus 30, in MOD sealing plate 20 opening process, the channel cross-sectional area of air door 41 is slowly increased.
Below as space is limited, only the structure of the concrete current-limiting apparatus 30 that the present invention uses and effect are described, but description does not below form limiting to the claimed invention.
