Multiple air outlets are provided with, make to form circulation air path connectivity structure between refrigerating chamber, refrigerating chamber and evaporator chamber.Covered behind air channel and set
Fan supporter is put, fan electromotor is then arranged on fan supporter, makes air forced circulation in air channel, and cold wind is passed through into air outlet
Deliver to refrigerating chamber and refrigerating chamber.At present, air channel bonnet and being connected for fan supporter are by multiple mode connects for screw, assembling
One ducting assembly takes at least 3 minutes.In order to coordinate the linear speed of streamline, also need for the operation to be refined as two small operations complete
Into making assembled in situ efficiency extremely low.
Utility model content
The purpose of this utility model is to provide a kind of rational in infrastructure, assembling to take short, efficiency of assembling air channel bonnet high
Structure, to overcome the deficiencies in the prior art.
What utility model purpose of the present utility model was realized in：Air channel rear cover structure, including refrigerating chamber air duct cover board,
Air channel bonnet, covers installation fan supporter behind air channel, and the fan supporter is used to install fan electromotor, the air duct cover board
At least two button holes are set on flange, and the fan supporter sets side cover plate, and the side cover plate extends to downwards air duct cover board
Flange outer sides, the side cover plate is provided with the projection being adapted with the button hole, and the fan supporter sets screw mounting seat, institute
Screw mounting seat is stated positioned at the opposite side of side cover plate.
Fan supporter installation step, sagging depth and the fan supporter of the installation step are set on the air duct cover board
Edge thickness is adapted.
Screw empty avoiding is set on the installation step.
Screw mounting post is set on the air duct cover board.
Wind guide tank is set on the air duct cover board, so as to be formed with main exhaust passage, the first horizontal branch air channel, the second horizontal branch
Air channel.
The lower wall in the first horizontal branch air channel is inclined to main exhaust passage；The second horizontal branch air channel includes shoulder and leg
Portion, the air outlet in the second horizontal branch air channel is arranged on the bottom of leg, and the shoulder in the second horizontal branch air channel is inclined to main exhaust passage,
In the junction of the second horizontal branch air channel shoulder Yu leg, dash sill are set.
The beneficial effects of the utility model are：Air channel bonnet is by the utility model with the matching structure design of fan supporter
Combination based on eye-splice, supplemented by screw, makes the overall assembling of ducting assembly to be reduced to either simplex sequence and time-consuming less than 1
Minute, substantially increase labor productivity.
Brief description of the drawings
Fig. 1 is that a kind of part of air channel rear cover structure of the present utility model splits schematic diagram.
Specific embodiment
The utility model will be further described below in conjunction with the accompanying drawings.
Referring to Fig. 1, a kind of air channel rear cover structure, including refrigerating chamber air duct cover board 3, air channel bonnet 2, peace is covered behind air channel
Dress fan supporter 1, the center of fan supporter sets motor cavity 11, and fan electromotor is arranged on motor cavity 11, air duct cover board
Flange at least two button holes 31 are set, fan supporter sets side cover plate, and side cover plate extends to downwards the flange of air duct cover board
Outside, side cover plate is provided with the projection 12 being adapted with button hole, and fan supporter sets screw mounting seat 13, and screw mounting seat is located at
The opposite side of side cover plate.
On air duct cover board 3, the installation site of correspondence fan supporter sets support breach 21, and gap edge is provided with blower fan branch
Frame installation step 22, the sagging depth of installation step is adapted with the edge thickness of fan supporter.Screw is set on installation step
Empty avoiding 23.Correspondingly, screw mounting post 32 is set in the inner side of air duct cover board.After assembling, screw mounting post 32 is kept away through screw
Empty 23 contact with screw mounting seat 13, and just fan supporter can be arranged on air duct cover board by a screw.
Wind guide tank is set on air duct cover board, so as to be formed with main exhaust passage, the first horizontal branch air channel 33, second horizontal branch's wind
Road 34.
The lower wall in the first horizontal branch air channel is inclined to main exhaust passage；Second horizontal branch air channel includes shoulder and leg, second
The air outlet in horizontal branch air channel is arranged on the bottom of leg, and the shoulder in the second horizontal branch air channel is inclined to main exhaust passage, second
Horizontal branch air channel shoulder sets dash sill 35 with the junction of leg.Refrigerating chamber is provided near the lower end return air inlet of air duct cover board
