Specific embodiment
The invention will be further described with reference to the accompanying drawing.
Referring to Fig. 1-5, a kind of air duct construction of switch, including knob 2, pedestal 4, switch 5, the pedestal setting are cold in refrigerator
Freeze on the air duct cover board 10 of room and be overall structure with air duct cover board, switch is by first switch plate 51, second switch plate 52, switch
Cover 53, switch base 54 form, and the first, second switchboard is located at switch base two sides, and convex clip button 55 is arranged on switch base, described
Convex clip button passes through pedestal and extend into the recessed button hole of knob 2, and upper rotary table 21 and the lower band of column 22, recessed button hole setting is arranged in knob 2
In the lower band of column 22.The first slide guide circular arc 41 and the second slide guide circular arc 42, the first, second slide guide circular arc is arranged in the bottom surface of pedestal 4
Concentric, the first, second switchboard are respectively set slide guide notch (511,521), and slide guide notch 511 and the first slide guide circular arc 41 are suitable
Match, slide guide notch 521 is adapted to the second slide guide circular arc 42, and the radius of the first slide guide circular arc is greater than the half of the second slide guide circular arc
Diameter.Fool proof block 56 is set in switch base, the setting inserting column 23 compatible with fool proof block in the lower band of column 22 of knob, inserting column 23
In the lower position of the lower band of column, fool proof block is half sleeve-shaped, and inner mold face is matched with inserting column alien invasion, and the setting of fool proof block is being opened
It closes in half side under seat.Therefore, cooperated by convex clip button and recessed button hole, assemble switch with knob 2, knob rotation can be driven
The switchboard of switch rotates, so as to adjust air door size.And since the bottom surface of pedestal is provided with the different slide guide circular arc of radius, and
And correspondingly, the slide guide notch matched with two slide guide circular arcs is provided on two switchboards, it is clear that the size of two slide guide notches
Be it is inconsistent, therefore, switch with the cooperation position of pedestal be it is unique, otherwise switch can not be coupled with knob.Equally
Reason, due to being provided with fool proof block, it is also uniquely fixed for making the relative position between switch base and knob.Therefore, pass through control
The position of knob processed can determine the size of air door.Station location marker is made on air duct cover board, knob respectively, helps to consume
Person accurately adjusts refrigerating chamber air force, makes up to desired temperature target.
In order to keep refrigerator freezing room Nei Guan more good-looking, it is provided with decorated disk on the position of refrigerating chamber airflow regulating switch,
Decorated disk is plastic part, and surface silk-screen has air door size/temperature control instructions mark, and it is beautiful that print can be applied on decorated disk
Pattern, keep product shape more beautiful and generous, pleasing.Decorated disk includes circlets 31, mounting disc, and rib 44 is arranged in pedestal
With decorations disk grab 43, elastic fastener 33, fool proof notch 32 be set in mounting disc, the decorations disk grab can spiral-lock in elastic fastener
On, the rib can be inserted into fool proof notch.By the cooperation of rib 44 and fool proof notch 32, make the opposite dress of decorated disk and pedestal
It is fixed with relationship, is not in the case where position assembly deviates, to ensure that the correctness of silk-screen position.Using dress
After adoring disk, there is no need to silk-screens pattern on air duct cover board, and the processing cost of air duct cover board can be made to reduce.
In order to keep the appearance of air quantity adjusting knob more good-looking, knob can be divided into main body and 1 two parts of knob lid, and from material
It makes comparison on material or color to distinguish, to keep appearance more prominent.The main body and knob lid of knob are assembled by snap, rotation
The bottom surface of button lid 1 has extended downwardly cover buckle 11, setting catching groove 25 compatible with the cover buckle in the upper rotary table 21 of knob 2；Rotation
The upward rotary table plane in the bottom surface of button lid is extended with support foot 12 of drawing money on credit, short support leg 13, corresponds to the position of short support leg in upper rotary table
Convex block 26 is set, and the height of convex block is equal to the difference in height of long and short support leg.The top surface of knob lid is equipped with mark.Cover buckle 11 and button
Slot 25 cooperates, and is mounted on knob lid 1 above rotary table, and cover buckle is two, is distributed in 180 degree, therefore, knob lid and main body
Assembly there are two types of possibility, in order to make between the two assembly relation reach uniqueness, set by the difference in height of long and short support leg
The cooperation of the position and height of meter and short support leg and convex block, fixes the assembly relation of knob lid and main body uniquely, reaches
The purpose of fool-proof design.
Above-mentioned specific embodiment is only the preferable specific embodiment of effect of the present invention, is not constituted to limit of the invention
System, it is all to make simple transformation person without creative work and to the design of the present invention, it belongs in the protection scope of the application.
