Problems solved by technology

[0003] The freezer door of the household refrigerator is connected with the freezer body by a connecting shaft. After opening the freezer door, cold air escapes, causing the temperature inside the freezer to rise and the food in the freezer to experience a high-temperature process; frequent opening of the door will lead to this frequent process
This not only causes the workload of the refrigerator to increase, but also is not conducive to the preservation of food.

Embodiment 1

[0024] see Figure 1-3 . An air curtain structure for a refrigerator, comprising a refrigerator door 1, which is pivotally connected to the cabinet body 3 of the refrigerator through a connecting shaft 2, and also includes an air pressure chamber, the inner surface of the refrigerator door 1 is provided with a first series of air holes 4, The first series of air holes 4 communicate with the air pressure chamber through pipelines; the pipeline between the first series of air holes 4 and the pressure chamber is provided with a rotary switch; the connecting shaft 2 is also used as a rotary knob of the rotary switch.

[0025] When the refrigerator door 1 is opened, the connecting shaft 2 will rotate. Since the connecting shaft 2 doubles as the rotary knob of the rotary switch, the rotary switch will be turned on at the same time when the refrigerator door 1 is opened, and the air in the air pressure chamber will pass through the first series of air holes 4 The gas is released, an...

Embodiment 2

[0031] see Figure 4-6 . An air curtain structure for a refrigerator, comprising a refrigerator door 1, which is pivotally connected to the cabinet body 3 of the refrigerator through a connecting shaft 2, and also includes an air pressure chamber, the inner surface of the refrigerator door 1 is provided with a first series of air holes 4, The first series of air holes 4 communicate with the air pressure chamber through pipelines; the pipeline between the first series of air holes 4 and the pressure chamber is provided with a rotary switch; the connecting shaft 2 is also used as a rotary knob of the rotary switch.

[0032] When the refrigerator door 1 is opened, the connecting shaft 2 will rotate. Since the connecting shaft 2 doubles as the rotary knob of the rotary switch, the rotary switch will be turned on at the same time when the refrigerator door 1 is opened, and the air in the air pressure chamber will pass through the first series of air holes 4 The gas is released, an...

Abstract

The invention relates to technical field of household appliances, in particular to an air curtain structure of a freezer. The air curtain structure comprises a freezer door and an air pressure bin. The freezer door is pivoted to a freezer body of the freezer through connecting shafts. The inner surface of the freezer door is provided with a first series of air holes which are communicated with the air pressure bin through pipelines. Each pipeline is provided with a rotary switch. The connecting shafts are also used as rotating button of the rotary switches, so that when the freezer door is opened, the rotary switches are opened, air in the air pressure bin is discharged through the first series of air holes, the air reaches to the original position of the freezer door to form an air curtain under action of air pressure, escape of cold air is prevented effectively, temperature in the freezer is prevented from rising, and long-term food freshness preservation is facilitated.

Description

technical field [0001] The invention relates to the technical field of home appliances, in particular to an air curtain structure of a refrigerator. Background technique [0002] Household refrigerators and freezers have become a necessity in people's daily life, and now basically every household has a refrigerator or freezer. [0003] The freezer door of the household refrigerator is connected with the freezer body by a connecting shaft. After opening the freezer door, cold air escapes, causing the temperature inside the freezer to rise and the food in the freezer to experience a high-temperature process; frequent opening of the door will lead to this The process is carried out frequently. This not only causes the workload of the refrigerator to increase, but also is not conducive to the preservation of food. Contents of the invention [0004] The object of the present invention is to provide a refrigerator with an air curtain structure, in which cold air in the refrige...
