Embodiment 1

[0050] The invention provides a vacuum heat-insulated refrigerator door with an air curtain structure, such as Figure 1-Figure 9 As shown, it includes: a door body 1 and a door frame 2, the door body 1 and the door frame 2 are mutually fitted and sealed; a first chamber 11 is arranged in the door body 1, and the first chamber 11 includes A plurality of first air vents 13 are opened on the door body 1; a second chamber 21 is arranged in the door frame 2, and the second chamber 21 includes a The second air vent 211, the first air vent 13 and the second air vent 211 are located on the surface where the door body 1 and the door frame 2 are fitted together; The pressure of the chamber 21 is used to form a directional airflow flowing from the second air outlet 211 to the first air outlet 13, and multiple directional airflows form an air curtain. The blowing mechanism blows air to the second chamber 21 to increase the pressure of the second chamber 21 , causing the airflow inside t...

Embodiment 2

[0061] This embodiment provides a control method for controlling the vacuum-insulated refrigerator door with an air curtain structure in Embodiment 1, including:

[0062] Judging the state of the door body 1, the door body 1 has a sensor, and the sensor judges the state of the door body 1 by detecting the sensing signal in real time;

[0063] When the door 1 is opened, the sensor sends a signal to control the blower mechanism to supply air and pressurize the second chamber 21; when the door 1 is closed, it is judged whether the second chamber 21 is closed;

[0064] When the second chamber 21 is closed, the pressure of the first chamber 11 is detected, and when the pressure is higher than the preset pressure threshold, the air blowing mechanism is controlled to extract the air of the first chamber 11 and Decrease to the preset pressure threshold, or less than the preset pressure threshold.

Abstract

The invention discloses a vacuum thermal insulating type cold storage door with an air curtain structure and a control method thereof. The vacuum thermal insulating type cold storage door comprises adoor body, a door frame, a first chamber, a second chamber and an air blowing mechanism; the door body and the door frame are mutually embedded and sealed; the first chamber is formed in the door bodyand comprises a plurality of air ports formed in the door body; the second chamber is formed in the door frame and comprises second air ports directly facing the first air ports; the first air portsand the second air ports are formed in mutually embedded surfaces of the door body and the door frame; the air blowing mechanism is used for increasing the pressure intensity of the second chamber toform a plurality of directional airflow flowing from the second air ports to the first air ports; the directional airflow form an air curtain; the second air ports directly face the first air ports; the ejected airflow is ejected into the first chamber through the first air ports; the directional airflow is distributed an open space range between the door body and the door frame to form the air curtain isolating the internal environment of a cold storage chamber from the external environment; and the airflow scours an object passing through the air curtain to realize a cleaning function.

Description

technical field [0001] The invention relates to the technical field of refrigeration equipment, in particular to a vacuum heat-insulating refrigerator door with an air curtain structure and a control method thereof. Background technique [0002] Cold storage and refrigerators are all refrigeration equipment. Refrigeration equipment is mainly used for constant temperature storage of food, dairy products, meat, aquatic products, poultry, fruits and vegetables, cold drinks, flowers, green plants, tea, medicines, chemical raw materials, electronic instruments, etc. [0003] However, when the refrigeration equipment is in use, usually the door of the refrigeration equipment is opened by taking the medicine, so that the corresponding refrigeration items can be taken out or put in. Existing refrigeration equipment usually has the following deficiencies: [0004] 1. There is a large difference between the temperature inside the refrigeration equipment and the outside temperature. ...
