The frost-free fridge has the advantages of simpleness and practicability. By arranging the frosting quantity sensor at a certain position, the utility model can exactly hold the frost melting opportunity on the evaporator, thus reaching the effect of reducing the electric consumption of the fridge, leading to more energy-saving fridge and improving the working efficiency.
Description
Technical field
The utility model relates to refrigerator, is specifically related to a kind of frost-free refrigerator-freezer of belt sensor.
Background technology
The tradition frost-free refrigerator-freezer generally is to adopt regularly defrost, i.e. time accumulation control defrost, and when the refrigerator cooling time reached a setting value, case can enter the defrost program automatically, and defrost reaches a setting-up time, and frost promptly finishes.Such defrost mode is subjected to artificial factor, often differs bigger with actual conditions, can control defrost exactly, thereby refrigerator power consumption is increased, and is unfavorable for energy-conservationly, and it is low to make efficient.
Summary of the invention
The technical problems to be solved in the utility model is how accurately to determine opportunity that frost is melted, reaches exactly the frost on the evaporimeter is melted, thereby reaches the purpose that reduces refrigerator power consumption, makes refrigerator more energy-conservation, increases work efficiency.
Above-mentioned technical problem of the present utility model solves like this, construct a kind of frost-free refrigerator-freezer, it is characterized in that, but near the sensor that frosting degree on the sensing evaporator is installed the evaporator of refrigerator, described frosting degree sensor is connected to the input port of microprocessor by signal processing unit, and the output port of described microprocessor can be controlled according to described frosting degree transducing signal and carry out defrost or refrigeration.
In the frost-free refrigerator-freezer that provides according to the utility model, described frosting degree sensor device is at the easiest frosting of evaporator of refrigerator position.
In the frost-free refrigerator-freezer that provides according to the utility model, described frosting degree sensor is an optical sensor.
