Embodiment 1

[0031] like figure 2 As shown, the present invention provides a refrigerator, comprising: a freezer compartment 1, a freezer compartment 2, and the freezer compartment is located above the freezer compartment. The freezer compartment 1 is provided with a freezer compartment air duct 111, namely a first air duct. The refrigerator compartment is provided with a refrigerator compartment air channel 21, namely the second air channel. The freezer air channel 111 is provided with an air inlet 112 , an air outlet 121 , a fan 122 , a first guide boss 116 and a water outlet 118 . The air inlet 112 is located near the top surface of the freezing compartment 1 .

[0032] The air duct 21 of the refrigerating compartment communicates with the air duct 111 of the freezing compartment through the air supply duct 113 . The opening at the junction of the air supply duct and the freezing air duct is located on the bottom surface of the freezing air duct, that is, the limiting surface of the...

Embodiment 2

[0041] like image 3 As shown, the present invention provides a refrigerator, comprising: a freezing compartment 1 and a refrigerating compartment 2 . The freezer is located above the refrigerator. A freezer air channel 111, namely a first air channel, is arranged in the freezer compartment 1 . At the same time, a refrigerating room air channel 21 is provided in the refrigerating room, that is, a second air channel, and an air outlet 211 is provided in the refrigerating room air channel 21 . The freezer air duct 111 communicates with the refrigerator compartment air duct 21 . The freezing chamber 1 is also provided with an evaporator (not shown in the figure).

[0042] The freezing duct structure of the refrigerator of the present invention is specifically referred to Figure 4-5 . In this embodiment, the freezer air duct 111 is formed by fastening the front air duct cover 12 and the rear air duct cover 11. At the same time, the air duct front cover 12 and the rear air du...

Embodiment 3

[0055] The difference between this embodiment and Embodiment 2 is that a part or all of the lower air outlet 1212 is located below the slope of the first air guiding boss 116 . In order to prevent the water flowing down the slope of the first diversion boss 116 from flowing into the lower air outlet 1212 and freezing the lower air outlet 1212 , the lower air outlet 1212 should be as far away from the first diversion boss 116 as possible. The lower air outlet can be arranged vertically or horizontally.

[0056] like Image 6 As shown, the lower air outlet 1212 is roughly rectangular, preferably, Image 6 Among them, the length of the side perpendicular to the bottom surface of the refrigerator is greater than the length of the side balanced with the bottom surface of the refrigerator, that is, it is vertically arranged. At the same time, the lower air outlet 1212 is located at the protrusion at the lower end of the freezer air duct 111 , and the depression in the middle of th...

Abstract

The invention relates to a household electric appliance, in particular to a refrigerator with a freezing and blocking prevention air duct structure. The refrigerator comprises a first storage chamber and a second storage chamber, wherein the first storage chamber is formed above the second storage chamber; an evaporator is arranged in the first storage chamber. The refrigerator further comprises a first air duct positioned in the first storage chamber and a second air duct positioned in the second storage chamber, wherein the first air duct is communicated with a space in the vicinity of the evaporator; an air supply passage is formed between the first and second air ducts; a first flow guide lug boss and water outlets are arranged in the first air duct; the first flow guide lug boss is positioned above the air supply passage to prevent water in the air ducts from flowing into the air supply passage and guide the water to the water outlets. According to the refrigerator, an air duct design for a top-freezing and bottom-cold storage or variable temperature refrigerator is provided, and by the lug boss designed in the air duct, water drops or water flow in the air duct in a freezing chamber can be prevented from flowing to a damper door to be frozen or block the air duct, and the air duct is prevented from being iced and further failing.

Description

technical field [0001] The invention relates to a household appliance, in particular to a refrigerator with an anti-freezing air duct structure. Background technique [0002] Today, the use of household appliances has become very popular. As a practical household appliance, refrigerators are favored by users. At present, the air-cooled refrigerators that realize frost-free indoors occupy a very large sales share in the refrigerator market. [0003] Air-cooled refrigerators on the market generally include a refrigerating (or variable temperature) compartment and a freezing compartment. The refrigerating (or variable temperature) compartment includes an inner container and a refrigerating (or variable temperature) air duct assembly arranged in the inner container. The freezing compartment includes a freezing inner container. It communicates with the freezer air duct assembly arranged in the freezer liner, the refrigerating (or variable temperature) air duct formed by the ref...
