Refreshing and sterilizing control device and the control method thereof for realizing safety temperature adjustment and timing in varying temperature compartment

Abstract

The invention discloses a refreshing and sterilizing control device and the control method thereof for realizing safety temperature adjustment and timing in a varying temperature compartment. The control device is used in the varying temperature compartment and comprises a gate controlled switch, a manual switch, a main control panel, an ultraviolet lamp, an LED refreshing lamp and a red warning lamp, wherein the gate controlled switch is used for starting the sterilizing and refreshing control device automatically when a door of the varying temperature compartment is closed and closing the sterilizing and refreshing control device compulsively when the door of the varying temperature compartment is opened; the manual switch is used for closing the sterilizing and refreshing control device compulsively and manually when the sterilizing and refreshing control device is in on-state for a long time, which is caused by that the gate controlled switch cannot work under the state that the door of the varying temperature compartment is opened; and the red warning lamp is started and closed synchronously with the ultraviolet lamp when the door of the varying temperature compartment is in open state. According to the control method provided by the invention, the interval time and the opening time for opening the sterilizing ultraviolet LED lamp are determined by the temperature set in the varying temperature compartment, and the opening of the refreshing LED lamp is determined comprehensively by the set temperature and the actual temperature in the varying temperature compartment.

Description

technical field [0001] The invention relates to the field of refrigerators, in particular to a control device and a control method thereof capable of realizing safe temperature adjustment, timing fresh-keeping and sterilization in a variable temperature chamber of a refrigerator. Background technique [0002] At present, the temperature-changing room of most refrigerators mainly realizes fresh-keeping function or sterilization function alone. The main methods include: vacuum zero-degree fresh-keeping technology: using a specific structure of fruit and vegetable box structure, and making the temperature obtain and long-term storage at around 0°C. To achieve freshness. Photosynthetic fresh-keeping technology: simulating natural light to irradiate fruits and vegetables to achieve the fresh-keeping function. This kind of fresh-keeping function has the disadvantages of difficult design, application limitations, invariable temperature, and high cost. Sterilization has light-activa...
