Description
Technical field
The electric-heating technology field of water is the utility model is related to, relates in particular to a kind of condensation generator.
Background technology
From the point of view of safety and service life, the danger that the water heater of electricity consumption is maximum is exactly dry combustion method.Dry combustion method is light then
Damage equipment, it is heavy then can fire hazard with cause personnel to injure.The He of Chinese utility model patent 201120039913.6
200920313815.X all disclose a kind of anti-dry burning device using a switch.It may be failed in view of switch
Risk, Chinese patent 200920119083.1 discloses " two-stage dry-heating preventing " of a kind of temperature control and switch protection
Technology.Particularly Chinese patent 200720149269.1, the original of dry combustion method can not thoroughly be avoided by not only analyzing a switch
Cause, the common weak point with temperature-sensitive element anti-dry is also analyzed, be exactly to react slow and poor reliability.In the Chinese patent
In, inventors herein propose with body expansion type temperature controller to improve the technology of the response speed of anti-dry burning device and reliability.But nothing
By body expansion type temperature controller response speed how soon, it is all that can just make the response of protectiveness after dry combustion method produces high temperature to move
Make, it is impossible to definitely prevent the generation of dry combustion method phenomenon.
Chinese patent 201310130435.3 discloses one kind and mutually confirms inspection with two switches, is acting frequently
Upper switch damage after alert anti-dry method.In theory, the technology can be solved thoroughly really
The problem of condensation generator dry combustion method.But the patented technology has following defect in implementation process：(1) because various scenes
Uncertain factor, such as the dust at scene and greasy dirt can influence the actions of two switches, the accident of dry combustion method or even have
Occur；(2) can only alert, necessarily occur if warning message can not be found in time, the problem of dry combustion method；(3) produce
Raw water vapour can the regelation in equipment, safety and protection structure hidden danger to equipment；(4) because two switches need
Larger installing space is wanted, so the volume of condensation generator is larger, inside can accumulate more condensed water all the time.
Therefore, it is necessary to develop a kind of water heater of really not dry combustion method.
The content of the invention
The utility model discloses a kind of condensation generator, it include shell 1, water tank 2, fan 3, PTC heating plates 4,
Control circuit 5, heat-insulating base 6 and LED signal lamp group 7；
Wherein a gland steam exhauster 21 is arranged at the top of water tank 2, and it exports through the steam drain 11 on shell 1 and allows caused water vapour
It is discharged to the outside of condensation generator；
Fan 3 on shell 1 blows out air-flow by the exhaust outlet 13 on shell 1, what is come out from steam drain 11
Water vapour blows remote and dispelled；
There is current detection circuit 54 in control circuit 5, control circuit 5 is according to the operating currents of the PTC heating plates 4 detected
Size, start fan 3 when thering is condensed water to be heated, blow remote and dispel water vapour；Control circuit 5 is according to detecting
The size of the operating current of PTC heating plates 4, after condensed water is all evaporated, when stopping one section of the power supply of PTC heating plates 4
Between, then power, move in circles to PTC heating plates 4 again, reduce the heat time of PTC heating plates 4, save the energy and extension
The service life of PTC heating plates 4；

The strength signal of curtage；Control circuit 5 just according to the testing result of current detection circuit 54, judges PTC heating plates 4
Temperature is either with or without more than its Curie temperature；
Heat-insulating base 6 plays two effects：First, PTC heating plates 4 are tightly pressed against the bottom of water tank 2, allow in water tank 2
Condensed water can be evaporated completely by from bottom-heated；Scatter and disappear, carry to the heat of surrounding environment second, reducing PTC heating plates 4
The efficiency and speed of high evaporation condensed water.
In use, control circuit 5 is powered, by self-test, LED signal lamp group 7 is issued by system and normally indicates to believe system
Number.According to set time, control circuit 5 is powered and changed the state of LED signal lamp group 7 to PTC heating plates 4, instruction PTC heating
Piece 4 works.After certain interval of time, the detection of control circuit 5 passes through the electric current of PTC heating plates 4, if the PTC detected
The electric current of heating plate 4 presets threshold more than one, illustrates have condensed water by evaporation and PTC heating plates 4 in water tank 2
Temperature is less than Curie temperature, and control circuit 5 keeps the electric current supply of PTC heating plates 4, at the same open fan 3 blow it is remote and dispel from
The water vapour that gland steam exhauster 21 is discharged.Period, control circuit 5 constantly detect the work of PTC heating plates 4 according to certain time interval
Make electric current.After the electric current of the PTC heating plates 4 detected is less than the threshold of setting, illustrate condensed water in water tank 2 by
All evaporate and be higher than Curie temperature with the temperature of PTC heating plates 4, control circuit 5 interrupts the electric current supply of PTC heating plates 4
Instruction state with change LED signal lamp group 7 closes fan 3 to be stopped after a period of time that is delayed.Hereafter, control
Circuit 5 processed just restarted " to be powered to PTC heating plates 4 from control circuit 5 and change LED signal lamp group 7 every 3~30 minutes
State " a complete circulation starting, the condensed water allowed in condensation generator can be evaporated in time.In advance
The threshold of setting can determine that the method for experiment is according to experiment：Condensation generator is allowed in the case of no condensed water
Dry combustion method more than 10 minutes, threshold set in advance is used as by the use of actually measure obtained electric current 110~200%.
The utility model for dry combustion method potential safety hazard and water vapour secondary condensation the shortcomings that, disclose one kind highest temperature
PTC heating plate of the degree no more than 300 DEG C controls the new method of a small fan for heating element heater and with the method for detection electric current
Condensation generator.When not having condensed water, the maximum temperature inside condensation generator is also no more than 180 DEG C, from root
The risk that condensation generator dry combustion method is eliminated in sheet and is caused the accident.During condensate evaporation, small fan is generation
Water vapour blow remote and dispel, avoid condensed water secondary the problem of condensing in equipment.Moreover, with it is existing using PTC as plus
The condensation generator of thermal element is compared, PTC heating plates of the present utility model be when no condensed water it is idle, both
Energy-conservation more can greatly extend the service life of condensation generator again.
The utility model makes condensation generator most by the use of the PTC heating plates 4 that resistance varies with temperature as heating element heater
High-temperature is restricted, and eliminates the possibility of dry combustion method, allows condensation generator can never dry combustion method.The utility model is also with control
Circuit 5 detects the electric current of PTC heating plates 4, fan 3 is opened when having condensate evaporation water vapour is blown remote and dispelled, kept away
Exempt from the secondary condensation of condensed water.According to the electric current of the PTC heating plates 4 detected, control circuit 5 of the present utility model is not cold
Stop the heating of PTC heating plates 4, energy-conservation and the service life for extending condensation generator when condensate.
