Abstract
nullThe utility model discloses a kind of air-cooler automatic Induction Heating defrosting device，It includes frosting induction installation、Electricity-heated defrosting device，Described frosting induction installation includes light coupling relay，Described electricity-heated defrosting device includes heating wire、Electrothermal tube、Implant、Insulating end，Described electrothermal tube is while being coil，Described light coupling relay uses reflective photoelectric switch to control opening and closing，And access in heating wire loop，The transmitting terminal of described reflective photoelectric switch and receiving terminal are positioned at the recess of described electrothermal tube，The electrothermal tube other end on the other side is hinged 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，Whole device enters defrost pattern，When defrost is complete，Receiving terminal receives optical signal，Whole device stops defrost pattern，This device is suitable for the defrost with the refrigerating plant such as air-cooler and monitoring，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: electricity-heated defrosting device, frosting induction installation；Described electricity-heated defrosting device include heating wire, electrothermal tube,
Implant, insulating end, described heating wire is positioned at described electrothermal tube, is implant therebetween, and described insulating end is positioned at described
The two ends of electrothermal tube, described electrothermal tube is coil；Described frosting induction installation includes light coupling relay, described optocoupler
Relay series connection accesses described heating wire loop, the control switch of described light coupling relay for reflective photoelectric switch, described instead
Penetrate the interior recess that the transmitting terminal of formula photoswitch is fixed on the coil part of described electrothermal tube with receiving terminal, on the other side two
It is fixed with reflecting piece at individual adjacent coil evagination.
It is also preferred that the left described reflecting piece is iron plate, it has reflecting coating, described reflecting piece one towards the one side of described transmitting terminal
Ride on the magnetic piece of adjacent electrothermal tube while be articulated with another side on described electrothermal tube by magnetic force, first push aside reflective during use
Sheet, snaps in coil between condensing tube, then reflecting piece is ridden on magnetic piece so that it is the luminous energy of reflection enters connecing of photoswitch
Receiving end.
Coil part of the present utility model snaps between condensing tube, utilizes the frosting journey between photoswitch detection fin
Degree, time when between fin without frosting, the receiving terminal of reflective photoelectric switch can receive optical signal, without frosting when between fin
Time, the receiving terminal of reflective photoelectric switch can receive optical signal, the state transition of photoswitch, can make to be connected on heating wire and return
The pattern of the light coupling relay in road carries out saltus step, thus realizes the knot according to frosting degree automatic shutter electricity-heated defrosting device
Really, here for making the saltus step of photoswitch cater to the change of defrost state, also need to add in its connection with light coupling relay
Phase inverter, make whole device sensing controlled state be: 1, photoswitch conducting time, heating wire loop disconnect；2, photoswitch is not
During conducting, heating wire loop is connected.Only use ball bearing made switch and element because of this utility model, therefore cost is low, and design is skilful
Wonderful, it is worthy to be popularized.
Accompanying drawing explanation
Fig. 1 is this utility model structural representation.
Detailed description of the invention
Embodiment one

Heating wire 3, electrothermal tube 2, implant, insulating end 1, described heating wire 3 is positioned at described electrothermal tube 2, is implant therebetween, and one
As use magnesium oxide, described insulating end 1 is positioned at the two ends of described electrothermal tube 2, and described electrothermal tube 2 is coil；Institute
State frosting induction installation and include that light coupling relay 6, the series connection of described light coupling relay access described heating wire 3 loop, described optocoupler
The control switch of relay 6 is reflective photoelectric switch 7, and the transmitting terminal of described reflective photoelectric switch 7 is fixed on receiving terminal
The interior recess of the coil part of described electrothermal tube 2, is fixed with reflecting piece 4 at two adjacent coil evaginations on the other side.
More specifically, described reflecting piece 4 is iron plate, and it has a reflecting coating towards the one side of described transmitting terminal, described instead
Mating plate 4 is while being articulated with another side on described electrothermal tube 2 and being ridden on 2 magnetic pieces 5 of adjacent electrothermal tube by magnetic force.
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.
