A sunscreen device for frozen goods on balcony using current sensor

Abstract

The invention discloses a balcony frozen products sun-proof device using a current sensor. The device comprises a cargo tank. The other side of the cargo tank is provided with a solar panel. The solar panel is electrically connected with a storage battery. The current sensor is arranged between the solar panel and the storage battery. The top of one side of the solar panel is connected with a buckle cover through a torsional spring shaft in a hinged mode. The top end of the side, provided with a mounting plate, of the cargo tank, is connected with a pull rod through a reset spring. One side of the cargo tank is connected with an exterior transformer. The transformer is electrically connected with a set of semiconductor chilling plates arranged in the cargo tank. A temperature control switch and an electronic switch are arranged between the transformer and the semiconductor chilling plates. The device is capable of effectively preventing frozen products putted out of balcony in winner from unfreezing caused by sunshine and ensuring the quality of frozen products so that users are relieved to store frozen products out of balcony.

Description

technical field [0001] The invention relates to the field of home appliances, in particular to a sunscreen device for frozen goods on a balcony using a current sensor. Background technique [0002] In the Northeast, the temperature in winter is very cold, especially in Heilongjiang, where the outdoor temperature has been below minus ten degrees for a long time. Even in Liaoning Province, the temperature has remained below minus five degrees for a long time. In such cold weather Under the circumstances, putting food outdoors can have a good preservation effect, which is equivalent to a natural refrigerator. In fact, many residents in the Northeast region store food on the storage boxes outside the balcony in winter, but even in winter, when the sun is shining When the irradiation is strong, the temperature of the food under direct sunlight will rise or even thaw due to solar radiation and other reasons, which will affect the quality of the food. Now there is a need for a stor...
