Automatic ultrasonic defrosting device

Abstract

The invention relates to an automatic ultrasonic defrosting device which comprises a shell. A refrigerating device is arranged in the shell and comprises a plurality of air coolers and an evaporator. The multiple air coolers are installed on one side of the shell. The evaporator comprises a plurality of cooling fins and a plurality of condensing pipes. An ultrasonic transducer device is arranged on one side of one air cooler and comprises an ultrasonic transducer and an ultrasonic generator. A frosting induction device is arranged on the other side of the shell and comprises a fixing part, an emitting device and a receiving induction device. The emitting device comprises a reflecting optoelectronic switch. The receiving induction device is arranged between the two corresponding cooling fins and located on the same straight line with the frosting induction device. By adoption of the automatic ultrasonic defrosting device, frosting can be automatically inducted, defrosting can be automatically conducted, the frosting condition of the air coolers is detected through the frosting induction device under the condition that the refrigerating effect is not stopped, the automatic ultrasonic defrosting device can automatically operate in a defrosting mode, the defrosting effect is good, and normal production is not affected, so that the production efficiency is high.

Description

technical field [0001] The invention relates to a device capable of automatically sensing the frosting of a cold air blower and ultrasonic defrosting. Background technique [0002] At present, defrosting can restore the cold and heat exchange capacity of the air cooler and improve the cooling effect. Otherwise, the cooling capacity of the refrigerator will be reduced or even not cooled or damaged. There are many types of air-cooler defrosting, such as electric defrosting, hot air defrosting, water defrosting, etc. When defrosting, the refrigerator must be stopped for cooling, and a considerable amount of heat is input, which consumes energy and affects production efficiency. Contents of the invention [0003] The object of the present invention is to overcome the above disadvantages, and provide an ultrasonic automatic defrosting device with non-stop defrosting, energy saving and high production efficiency. [0004] The purpose of the present invention is achieved by the...
