Refrigerating chamber ventilation guarantee platform

Abstract

The invention relates to a refrigerating chamber ventilation guarantee platform. The refrigerating chamber ventilation guarantee platform comprises a first cabinet body, a second cabinet body, range identification equipment and fan driving equipment; the first cabinet body comprises a thermal insulation plate, a first evaporator, a freezing chamber, a condenser, a first door body and a first handle, and the first handle is arranged on the first door body; the second cabinet body is arranged under the first cabinet body and comprises a second evaporator, a water draining pipe, a refrigerating chamber, a water receiving disc, a compressor, a second door body and a second handle, and the second handle is arranged on the second door body; the range identification equipment is used for identifying the total number of pixel points, occupied by all targets in a to-be-processed area, of the to-be-processed area and dividing the total number of the pixel points, occupied by all the targets, ofthe to-be-processed area by the total number of pixel points of the to-be-processed area to obtain a proportional reference value; and the fan driving equipment is connected with the range identification equipment and a fan in the refrigerating chamber and used for determining the fan driving power in direct proportion to the proportional reference value on the basis of the proportional referencevalue. According to the refrigerating chamber ventilation guarantee platform, the ventilation effect in the refrigerator refrigerating chamber can be guaranteed.

Description

technical field [0001] The invention relates to the fresh-keeping field of a refrigerator, in particular to a ventilation guarantee platform for a refrigerator. Background technique [0002] The cold room is a preservation method for the cooled food at a cold temperature (usually above freezing point), especially for fruits and vegetables, mainly to delay their life metabolism process as much as possible and keep their freshness. [0003] Generally, the temperature of the refrigerator is -1°C to 8°C, and the cold storage stored at this temperature is often called a high-temperature cold storage. Refrigeration can extend the shelf life of fresh foods and processed products by reducing the rate of biochemical reactions and changes caused by microorganisms. For most foods, refrigeration does not prevent food spoilage like canning, dehydration or freezing, but only slows down the spoilage rate of food, so it is actually a relatively weak preservation technology. However, not a...

Problems solved by technology

[0004] In order to solve the technical problem of reducing the freshness preservation effect caused by too much food in the current refrigerator, the invention provides a ventilation guarantee platform for the refrigerator, which analyzes the food occupation range in the refrigerator, and determines the drive of the fan in the refrigerator proportional to the occupation range. Power, to ensure the ventilation efficiency in the cold storage room, to ensure its freshness preservation effect; at the same time, before analyzing the image of the occupied area, on the basis of image smoothing, the smoothed image is executed with the histogram corresponding to the equalization level of the collected histogram Image equalization processing to output self-adaptive processing images; also built a valuable processing area identification mechanism based on pixel saturation distribution, which improves the efficiency of image processing
