Embodiment 1

[0054] see Figure 1-5 As shown, the present invention is a single-system multi-channel air inlet air duct device, which includes the air duct device body, and the air duct device body includes the lower air duct foam 1, the upper air duct foam 2, the fixed support block 3, the double damper 4, the fixed support Seat 5, single damper 6, freezer compartment air outlet 7, variable room air inlet 8, refrigerating room air inlet 9, refrigerating room variable temperature box air inlet 10.

[0055] The tuyeres on the foam 1 of the lower air passage are corresponding to the air outlets on the foam 2 of the upper air passage to form a complete freezer compartment air outlet 7, variable room air intake 8, refrigerating compartment air intake 9, and refrigerating compartment variable temperature box air intake 10.

[0056] The fixed support base 5 is installed at the air inlet 8 of the variable room, and the single damper 6 is installed on the fixed support base 5 for controlling the o...

Embodiment 2

[0059] Based on the technical solution described in the first embodiment above. see Figure 6-7 As shown, the inside of the foam 1 in the downflow channel is a hollow cavity. The three different surfaces of the foam 1 in the lower air channel are respectively provided with an air outlet 101 for the lower freezing chamber, an air inlet 102 for the lower variable room, and an overall air inlet for the lower refrigerating chamber. The overall air inlet of the lower refrigerating room includes an air inlet 103 of the lower refrigerating room and an air inlet 104 of the variable temperature box of the lower refrigerating room. The inside of the foam 2 in the upper air duct is a hollow cavity.

[0060] see Figure 8-11 As shown, the three different surfaces of the foam 2 in the upper air channel are respectively provided with an air outlet 201 for the upper freezer, an air inlet 202 for the upper variable room, and an air inlet 203 for the upper refrigerator.

[0061] see Figu...

Embodiment 3

[0084] Based on the technical solution of the second embodiment above, a refrigerator includes a refrigerator in which a single-system multi-channel air inlet air duct device in the second embodiment is installed. The refrigerator includes a freezing liner, a temperature-changing liner, and a refrigerating liner.

[0085] see Figure 6-7 As shown, the lower air duct foam 1 is provided with a lower first fitting groove 115 , a lower second fitting groove 116 , and a lower third fitting groove 117 . The lower first assembly groove 115 is in interference fit with the refrigerated liner, the lower second assembly groove 116 is in interference fit with the temperature-changing liner, and the lower third assembly groove 117 is in interference fit with the refrigerated liner. The effect of the interference is to prevent leakage. The foaming liquid prevents the foaming liquid from entering the inner cavity of the air duct. It is designed to interfere with another function, which can ...

Abstract

The invention discloses a single-system multi-path air inlet duct device and a refrigerator with the same, and relates to the technical field of refrigerators. Comprising an air duct device body, and a complete freezing chamber air outlet, a variable-temperature chamber air inlet, a refrigerating chamber air inlet and a refrigerating chamber variable-temperature box air inlet are formed by corresponding air openings in lower air duct foam and air openings in upper air duct foam. The single air door is installed on the fixed supporting seat and used for controlling opening and closing of an air inlet of the temperature changing chamber, the fixed supporting blocks are installed at an air inlet of the refrigerating chamber and an air inlet of the temperature changing box of the refrigerating chamber, and the double air doors are installed on the fixed supporting blocks and used for controlling opening and closing of the air inlet of the refrigerating chamber and the air inlet of the temperature changing box of the refrigerating chamber. Through cold storage air inlet, direct connection from the freezing chamber can be achieved, the cooling capacity loss is reduced, the refrigeration efficiency can be improved, and then the power consumption is reduced.

Description

technical field [0001] The invention belongs to the technical field of refrigerators, and in particular relates to an air inlet duct device of a refrigerator, in particular to a single-system multi-channel air inlet duct device and a refrigerator having the same. Background technique [0002] With the existing air duct installation, the air intake of the refrigerating room needs to pass through the variable room, the air intake path is long, and the loss of cooling capacity is large, which indirectly affects the power consumption. [0003] The existing air duct device has a complex structure of parts and many plastic parts, resulting in a high total cost of parts; moreover, multiple injection molds need to be manufactured, which greatly increases the cost of molds and indirectly increases product costs, which is not conducive to product competitiveness. In addition, the air duct device is difficult to assemble, the process is complex, time-consuming and labor-intensive, and ...
