Abstract
The utility model provides a defrosting sensor of an automatic defrosting device for a refrigeration system. The utility model comprises a luminescent device for detecting the thickness of frost, a photoreceptor, a fixed bracket and conductor wires. Which frost exists or not, the photoreceptor is affected by the change of light intensity to detect the thickness of frost, hereby realizing the automatic control on the defrosting of the refrigeration system. With the defrosting sensor, the utility model has the advantages of accurate and timely defrostation, reduction of energy consumption and increased efficiency of the refrigeration system.
Description
The present invention is a kind of refrigeration system automatic defrosting defrosting sensor.
The automatic defrosting device of present refrigeration system, usually adopt the timing controlled defrost, even it is many that its shortcoming is a frosting degree, but because of not carrying out defrost less than the regular hour, in contrast, but periodically start defrosting device when not having frosting and carry out defrost, thereby increased energy consumption, influenced the efficient of refrigeration system.
The purpose of this invention is to provide a kind of Defrostingsensor for refrigerating system, it is thick so that realize opening, stopping of automatic control frost device to detect frost automatically by it.Thereby improve the efficient of refrigeration system.
The present invention is achieved in that it is useful on the thick luminescent device of detection frost, photoreceptor, fixed support and connection lead.Luminescent device can become the form of correlation or reflection to be installed on the fixed support with photoreceptor.During use defrosting sensor is installed in the position that needs defrost, when the refrigeration system frosting, the luminous intensity that is subjected to of photoreceptor will change, like this by testing circuit just can detect the frost thickness and control defrosting device and when frost reaches certain thickness, carry out defrost.Also the thermometric temperature-sensitive device can be housed in this defrosting sensor, detect the temperature of frost when melting fully by it and stop defrost with the control defrosting device.Luminescent device, the most handy waterproof insulation material of photoreceptor are enclosed on the fixed support admittedly.Luminescent device can adopt infrarede emitting diode, and photoreceptor can adopt photodiode.Can adopt the good material of heat conductivility to manufacture admittedly seal support.Thermometric can adopt thermistor with temperature-sensitive device.
The automatic detection frost that the present invention can be used for refrigeration system is thick, and carries out defrost in view of the above accurately and timely, thereby has reduced energy consumption and improved the efficient of refrigeration system.
Accompanying drawing is the concrete structure figure according to an enforcement provided by the invention.
The present invention is described further below in conjunction with accompanying drawing.
1 is fixed support in the accompanying drawing.Can adopt adhesive or be fixed on the position that needs defrost with screw, rivet.2 is photodiode.3 is infrarede emitting diode.4 is thermistor.5 is the waterproof insulation fixed sealing material.6 for drawing lead.When the refrigeration system frosting.Photodiode 2 and infrarede emitting diode 3 surfaces will frostings.Make photodiode 2 weakened by luminous intensity.Can detect white thick by testing circuit.When under the occasion of high light is arranged, using, can on photodiode 2, add infrared fileter to eliminate the interference of visible light.When the frosting position reached uniform temperature usually, frost can melt fully.Detect the temperature at frosting position by thermistor 4, stop defrost with the control defrosting device.Gu envelope can adopt epobond epoxyn with waterproof material.
Claims (4)
1. a defrosting sensor that is used for refrigeration system is characterized in that it is useful on thick luminescent device, photoreceptor, fixed support and the lead of detection frost.
2. defrosting sensor according to claim 1 is characterized in that it also has the thermometric temperature-sensitive device.
3. according to claim 1,2 described defrosting sensors, it is characterized in that described luminescent device, photoreceptor and temperature-sensitive device are to be enclosed on the fixed support admittedly with insulating materials.
4. defrosting sensor according to claim 1 is characterized in that described luminescent device is an infrarede emitting diode, and photoreceptor is a photodiode.
