Problems solved by technology

Freezers are divided into air-cooled refrigerators and direct-cooled refrigerators. During the use of direct-cooled refrigerators, negative pressure is formed due to the low temperature inside the cabinet. When the door is opened, a large amount of external air will carry water vapor into the cabinet. As a result, frost is formed on the surface of the inner tank of the cabinet, and the conventional method is to manually defrost or stop defrosting by the user, which is time-consuming and laborious, resulting in poor user experience

Abstract

The invention discloses a phase-change defrosting device, refrigeration equipment and a defrosting method. The phase-change defrosting device comprises a mounting box, an energy storage tube, an electric heater, an inner connecting tube and an outer connecting tube, wherein a mounting cavity is formed in the mounting box, an air inlet connector and an air outlet connector which are in communicatedwith the mounting cavity are arranged on the mounting box, inserting holes are formed in the mounting box, the inner connecting tube is connected with the air inlet connector, and the outer connecting tube is connected with the air outlet connector; and the energy storage tube comprises a heat conduction tube body and a phase change energy storage material arranged in the heat conduction tube body, the energy storage tube and the electric heater are arranged in the mounting cavity, the electric heater is attached to the energy storage tube, and one end of the energy storage tube penetrates through the insertion holes and extends out to the outside of the mounting box. The air entering the refrigeration equipment is frosted and dehumidified by the phase-change defrosting device, and automatic defrosting is realized by electric heating so as to improve the user experience.

Description

technical field [0001] The invention relates to refrigeration equipment, in particular to a phase change defrosting device, refrigeration equipment and a defrosting method. Background technique [0002] At present, refrigeration equipment (refrigerators, freezers, etc.) are commonly used electrical equipment, and refrigerators are widely used because of their large storage capacity. Freezers are divided into air-cooled refrigerators and direct-cooled refrigerators. During the use of direct-cooled refrigerators, negative pressure is formed due to the low temperature inside the cabinet. When the door is opened, a large amount of external air will carry water vapor into the cabinet. As a result, frost is formed on the surface of the inner tank of the cabinet, and the conventional method is to manually defrost or stop defrosting by the user, which is time-consuming and laborious, resulting in poor user experience. How to design a refrigeration device with automatic defrosting t...
