Technical Problem

Existing refrigerators lack humidity control in their humidity preservation zones, making mature foods susceptible to microbial damage and spoilage under high humidity conditions.

Method used

Design a refrigerator with a dedicated freshness preservation zone, equipped with a gas sensor, air duct assembly, humidifier, and humidity sensor. The control panel automatically adjusts humidity and temperature according to the ripeness of the food, including the opening and closing of the air outlet damper, return damper, and humidifier, to achieve intelligent humidity control.

Abstract

The application provides a fresh-keeping special area refrigerator and a control method, which comprises: a fresh-keeping special area composed of a cover plate and arranged in a refrigerating chamber; a gas sensor arranged in the fresh-keeping special area and away from the door; an air duct assembly arranged in the fresh-keeping special area and away from the door; a humidifying device arranged in the fresh-keeping special area and located at the top of the fresh-keeping special area; a humidity sensor arranged in the fresh-keeping special area and close to the humidifying device; and a control panel arranged at the top of a box body and away from the fresh-keeping special area. The control panel is electrically connected with the gas sensor, the air duct assembly, the humidifying device and the humidity sensor, so as to solve the problem that the current refrigerator lacks humidity regulation and control, and high-maturity food is destroyed by microorganisms and deteriorated under high-humidity conditions.
