Abstract
nullThe utility model discloses a kind of sensing microwave defrost air-cooler automatically，It includes shell、Blower fan group、Refrigerating plant、Frosting induction installation、Microwave defrosting device，Described frosting induction installation includes light coupling relay，Described microwave defrosting device includes magnetron，Described light coupling relay uses reflective photoelectric switch to control opening and closing，And access in magnetron control loop，Described reflective photoelectric switch is securable on fin，The other end on the other side is fixed with reflector plate，When frosting，The optical signal that photoswitch sends is blocked by frost，Receiving terminal cannot receive optical signal，Now light coupling relay conducting，Magnetron starts，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 electricity-heated defrosting, 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 shell, blower fan group, refrigerating plant, frosting induction installation, microwave defrosting device, described microwave technology
Frost device, frosting induction installation constitute sensing microwave defrosting device automatically；Described blower fan is assembled in side in described shell, wind direction
Relative with described refrigerating plant, described refrigerating plant includes condensing tube, vaporizer, fin, bypassing circulation device；Described microwave
Defrosting device includes magnetron and control circuit thereof；Described frosting induction installation includes light coupling relay, described light coupling relay
Series connection accesses the control circuit of described magnetron, the control switch of described light coupling relay for reflective photoelectric switch, described instead
Penetrating one end that the transmitting terminal of formula photoswitch is fixed on the two panels fin of vaporizer with receiving terminal, this two panels on the other side dissipates
The backing other end is fixed with reflecting piece.
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 microwave defrosting device also includes closing door, and control the electric control gear of its opening and closing, described closing door
It is loaded on the air port of air-cooler, closes while described magnetron starts, open while described magnetron is out of service.
This utility model utilizes microwave to carry out defrost, will be temporarily forming " microwave oven " of closing, and work as heat radiation inside air-cooler
Time between sheet without frosting, the receiving terminal of reflective photoelectric switch can receive optical signal, when between fin during frosting, reflection type photoelectricity
The receiving terminal of switch cannot receive optical signal, and the state transition of photoswitch can make to be connected in magnetron control circuit
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, magnetron control circuit disconnect, closing door is opened；2, light
When electric switch is not turned on, magnetron control circuit is connected, and closing door is closed.Only use because of this utility model ball bearing made 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.

For reflective photoelectric switch 2, the transmitting terminal of described reflective photoelectric switch 2 and receiving terminal are fixed on the two panels fin of vaporizer
One end of 9, this two panels fin 9 other end on the other side is fixed with reflecting piece 4.
More specifically, described reflecting piece 4 is iron plate, and it has reflecting coating towards the one side of described transmitting terminal.
More specifically, described microwave defrosting device also includes closing door 6, and controls the electric control gear of its opening and closing, described envelope
Close door 6 and be loaded on the air port of air-cooler, close while described magnetron 3 starts, while described magnetron 3 is out of service
Opening, the electric control gear controlling closing door opening and closing here should be to be connected with the control circuit of magnetron by another relay, its
The power supply circuits of itself are independent.
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.
