Abstract
A kind of waterproof anti-explosion type MOD, including housing, damper is provided with the housing, damper upper end is provided with gear reduction, the housing upper end is provided with cover plate, and gasket seal is provided between housing and cover plate, prevents water from flowing into enclosure interior from the gap of cover plate and housing assembling.Solve the water that common electric air door produces during automatic defrosting and gap can be assembled by cover plate and housing and flow into enclosure interior, so as to improve the security performance of air door, with simple structure, it is easy to operate the characteristics of, so as to improve the security performance of air door.
Description
Technical field
The utility model is related to a kind of waterproof anti-explosion type MOD, and the anti-of MOD is used on particularly a kind of refrigerator
Water explosion-proof electric air door.
Background technology
FMB type MODs are after stepper motor connects special driving power supply, by set of gears deceleration transmission
Mechanism, drives one to fan swung, by stepper motor rotating and pulse step number come the opening and closing angle of controlling baffle plate, so as to control
The cold flow of cold compartment of refrigerator processed.
Using the refrigerator of MOD, inevitably there is frost, showing as air door can not normally be opened and closed, its
Reason is that damper is frozen and cannot be operating normally.There are the presence of condensed water, low temperature bar in the refrigerator air duct of normal work
Frost can be condensed under part, it usually needs periodically defrosting, and MOD can relatively easily automatic defrosting, by MOD frame
A heating strip on the cloth of frame air port periphery, makes to be difficult frosting at wind passage mouth, but the working environment of inevitable MOD simultaneously
There is the presence of water, when water is from the motor circuit plate that housing and cover plate gap enter in housing, generation peace can be used to air door
Full hidden danger.
Utility model content
The utility model its purpose is that a kind of waterproof anti-explosion type MOD of offer, solves common electric air door and exists
The water produced during automatic defrosting can assemble gap and flow into enclosure interior by cover plate and housing, improve the security of air door
Can, with simple structure, it is easy to operate the characteristics of, so as to improve the security performance of air door.
The technical scheme realized above-mentioned purpose and take, including housing, are provided with damper, damper in the housing
Upper end is provided with gear reduction, and the housing upper end is provided with cover plate, gasket seal is provided between housing and cover plate, prevent water from
Cover plate flows into enclosure interior with the gap of housing assembling.
Beneficial effect
The utility model has advantages below compared with prior art.
The utility model has the advantages that by setting gasket seal between cover plate and housing, solving common electric air door
The water produced during automatic defrosting can assemble gap and flow into enclosure interior by cover plate and housing, so as to improve air door
Security, with simple structure, it is easy to operate the characteristics of, so as to improve the security performance of air door.
Brief description of the drawings
The utility model is described in further detail below in conjunction with the accompanying drawings.
Fig. 1 is structural representation of the present utility model；
Shown in figure：1. the damper of 2. gasket seal of cover plate, 3. gear reduction, 4. housing 5..
Specific embodiment
The present apparatus includes housing 4, as shown in figure 1, being provided with damper 5 in the housing 4, the upper end of damper 5 is provided with
Gear reduction 3, the upper end of the housing 4 is provided with cover plate 1, and gasket seal 2 is provided between housing 4 and cover plate 1, prevents water from lid
Plate 1 is flowed into inside housing 1 with the gap of the assembling of housing 4.
Multiple screws are provided between the cover plate 1 and housing 4, cover plate 1 is locked with housing 4 by fixing bolt, make lid
The compression seal pad 2 of plate 1 reaches waterproof purpose.
The utility model by increasing gasket seal 2 at the cooperation of housing 4 and cover plate 1, by fixing bolt by cover plate 1
Locked with housing 4, make the compression seal pad 2 of cover plate 1, prevent MOD water in the course of the work from being filled with housing 4 from cover plate 1
The gap matched somebody with somebody is flowed into inside air door, improves MOD security performance in the course of the work.
