Abstract
nullThe utility model discloses a kind of air-cooler and automatically sense the antifreeze defrosting device of hot water，It includes frosting induction installation、Hot water defrosting device，Described frosting induction installation includes light coupling relay，Described hot water defrosting device includes defrost shower nozzle、Heating plant、Control valve，Described light coupling relay uses reflective photoelectric switch to control opening and closing，And access in the control loop of hot water defrosting device，Transmitting terminal and the receiving terminal of described reflective photoelectric switch are fixed between fin，Reflecting piece is fixed between the fin that it is relative，When frosting，The optical signal that photoswitch sends is blocked by frost，Receiving terminal cannot receive the optical signal being reflected back，Now light coupling relay conducting，Defrost shower nozzle starts hot-water spraying，Whole device enters defrost pattern，When defrost is complete，Receiving terminal receives optical signal，Whole device stops defrost pattern，This device is applicable to defrost and the monitoring of the refrigerating plants such as air-cooler，Design ingenious，With low cost，It is worthy to be popularized.
Description
Technical field
This utility model relates to art of refrigeration units, particularly relates to a kind of dress that can automatically sense air-cooler frosting defrost
Put.
Background technology
Air-cooler, is divided into refrigerating industry air-cooler and Household air cooler, industry air-cooler to be generally used for freezer, Cold Chain Logistics
In refrigerating environment, domestic are again Water cooled air conditioners, are a kind of evaporated cooling ventilations integrating cooling, ventilation, dust-proof, taste removal
Unit.Commonly use in industry is dry cold blower fan.It is to force outside cooling tube by the heat exchange evaporation comb in air-cooler by air
The air of flowing, in actual use, can produce frost, affect refrigerating efficiency, now need to carry out in air-cooler
Defrost, is typically main defrost means with hot water defrost, aquation frost, but defrost is opened and many manually opening and to arrange the time is
Main, rare real-time monitoring frosting degree automatic defrosting device.
Summary of the invention
This utility model is for prior art and the above-mentioned deficiency of device, in order to automatically sense frosting defrost, propose with
Lower design: structure includes: include hot water defrosting device, frosting induction installation；Described hot water defrosting device includes defrost shower nozzle, confession
Thermal, control valve, described heating plant connects described control valve, and described control valve is also connected with described defrost shower nozzle；Described
Frosting induction installation includes light coupling relay, and described light coupling relay controls the opening and closing of described control valve, and described optocoupler continues
The control switch of electrical equipment is reflective photoelectric switch, and the transmitting terminal of described reflective photoelectric switch and receiving terminal are fixed on vaporizer
One end of two panels fin, this two panels fin other end on the other side is fixed with reflecting piece；Described heating plant also wraps
Including ethylene glycol and add mouth, glycol concentration meter, air vent is arranged at its top.
It is also preferred that the left described reflecting piece is iron plate, it has reflecting coating towards the one side of described transmitting terminal.
It is also preferred that the left described control valve is electromagnetic valve, described heating plant is boiler or apparatus for heating water by solar energy.
This utility model when between fin without frosting time, the receiving terminal of reflective photoelectric switch can receive optical signal, when
Between fin during frosting, the receiving terminal of reflective photoelectric switch can not receive optical signal, and the state transition of photoswitch can make
The pattern of light coupling relay carries out saltus step, thus realizes the result according to frosting degree automatic shutter microwave defrosting device, here
For making the saltus step of photoswitch cater to the change of defrost state, phase inverter also need to be added in its connection with light coupling relay,
Make whole device sensing controlled state be: 1, photoswitch conducting time, control valve close, not defrost；2, photoswitch is not turned on
Time, control valve opens, and defrost shower nozzle is sprayed water, and enters defrost state, adds mouth and row owing to this utility model is provided with ethylene glycol
QI KOU, can regulate the defrost liquid i.e. concentration of glycol water at 50%-60% so that the freezing point of defrost liquid own is permissible
Maintain a relatively low level, will not freeze, improve defrost efficiency, and only use because of this utility model ball bearing made to switch
And element, therefore cost is low, designs ingenious, is worthy to be popularized.
Accompanying drawing explanation
Fig. 1 is this utility model structural representation.
Detailed description of the invention
Embodiment one
This utility model includes hot water defrosting device, frosting induction installation as shown in Figure 1；Described hot water defrosting device includes
Defrost shower nozzle 3, solar water heater 7, electromagnetic valve 6, the water side of described solar water heater 7 connects described electromagnetic valve 6, described
Electromagnetic valve 6 is also connected with described defrost shower nozzle 3；Described frosting induction installation includes light coupling relay 1, described light coupling relay 1
Controlling the opening and closing of described electromagnetic valve 6, the control switch of described light coupling relay 1 is reflective photoelectric switch 2, described reflecting light
The transmitting terminal of electric switch 2 and receiving terminal are fixed on one end of the two panels fin 5 of vaporizer, this two panels fin on the other side
5 other ends are fixed with reflecting piece 4；Ethylene glycol is had to add mouth, glycol concentration meter above the water storehouse of described solar water heater,
Air vent is arranged at its top.
Concrete, described reflecting piece 4 is iron plate, and it has reflecting coating towards the one side of described transmitting terminal.
These are only this utility model preferred embodiment, therefore the scope that this utility model is implemented can not be limited according to this, i.e.
The equivalence change made according to this utility model description and decoration, all should belong in the range of this utility model covering.
