Energy-saving control device of fruit and vegetable storage short-term fresh-keeping system for winter

Abstract

The invention discloses an energy-saving control device of a fruit and vegetable storage short-term fresh-keeping system for winter. The device comprises a box body and a base, wherein the box body iswrapped with a thermal insulation material layer, the top of the box body is provided with a ventilation opening, the left side and the right side of the box body are each provided with a shutter anda permanent magnet, the front end face of the box body is provided with a double-layer glass sliding window, the base is provided with an arc-shaped track, the track penetrates through an opening inwindow glass, one half of the track is indoor, the other half of the track is outdoor, and the box body moves on the track along the track. The shape and size of the opening are consistent with thoseof the outer contour of the box body, and thus the box body can and just can pass through the opening; baffles are arranged at both ends of the track, electromagnets are arranged on the inner sides ofthe baffles, and the electromagnets generate electromagnetic force when powered on so as to push the box body to move and provide kinetic energy for movement of the box body, and are attracted by thepermanent magnets on the box body when powered off so as to limit movement of the box body. With the device, the problem about how to store a large number of fruits and vegetables in winter can be solved, the storage and fresh-keeping time of the fruits and vegetables is prolonged, and the device has the characteristics of being energy-saving, environmentally friendly, simple in structure and good in implementation effect.

Description

Technical field [0001] The invention belongs to the technical field of energy saving, and particularly relates to an energy saving control device and method for a short-term fresh-keeping system for fruit and vegetable storage in winter. Background technique [0002] Usually, fruits and vegetables are stored in cold storage or refrigerator to ensure the freshness of fruits and vegetables within a certain period of time. But sometimes it is necessary to store a large amount of fresh fruits and vegetables for a short period of time, which is not convenient to store in the refrigerator. For example, a large amount of fruits and vegetables are often stored around the Spring Festival. It is winter at this time, but due to the influence of heating, the indoor temperature is high. Too long, otherwise it is easy to produce mildew, and the fruits and vegetables may be frozen when the outdoor temperature is low. Summary of the invention [0003] In order to overcome the above-mentioned sho...
