Detailed description of the invention
In the present embodiment, as it is shown in figure 1, wind cooling refrigerator includes cold room 1 and refrigerating chamber 2；Vaporizer 3 is positioned at refrigerating chamber 2
Fan housing after, this vaporizer 3 end is embedded in foaming layer 12 and leads to cold room 1；
The moisturizing module of a kind of wind cooling refrigerator is provided in the cold room 1 of wind cooling refrigerator, as in figure 2 it is shown, moisturizing module includes:
Moisturizing fan 6, moisturizing vaporizer 7, fan housing 8, moisturizing evaporator heater 9a, water storage case heater 9b, level sensor
10 and water storage case 11；
Moisturizing vaporizer 7 is to be coiled to form by the evaporator tube 4 being connected on vaporizer 3；I.e. from being positioned at after refrigerating chamber 2
Concatenate out two vaporizers on vaporizer 3 and extend coil pipes 4 through refrigerator back foaming layer 12 to cold room 1, be coiled into moisturizing evaporation
Device 7；It is provided above fan housing 8 at moisturizing vaporizer 7；In fan housing 8, be in moisturizing vaporizer 7 is provided above guarantor
Wet wind fan 6；It is provided around moisturizing evaporator heater 9a at moisturizing vaporizer 7；In being embodied as, moisturizing vaporizer heats
Device 9a can be attached in fan housing 8, it is also possible to directly fits with moisturizing vaporizer 7；Fixed range below moisturizing vaporizer 7
Inside it is provided with water storage case 11；Certain distance is kept, it is simple to moisturizing vaporizer 7 surrounding air flows between water storage case 11 and fan housing 8；
Water storage case heater 9b it is provided with in the outside of water storage case 11；Wherein, moisturizing evaporator heater 9a and water storage case heater 9b
For independent control；Level sensor 10 it is provided with in water storage case 11；The water level in water storage case 11 is obtained with level sensor 10
Amount, thus control the keying of water storage case heater 9b；
With the operating of moisturizing fan 6 and moisturizing evaporator heater 9a, the poly-aqueous vapor stayed on moisturizing vaporizer 7 is dropped to
In water storage case 11, form aqueous vapor collection structure when cold room 1 freezes；
With the operating of moisturizing fan 6 and water storage case heater 9b make condensate evaporation in water storage case 11 in cold room 1,
Form the humidifying structure of cold room 1.
Concrete, the control method of a kind of wind cooling refrigerator moisturizing module is as follows:
As it is shown on figure 3, when cold room 1 request refrigeration or other several rooms the most also request refrigeration, vaporizer 3 and moisturizing
Vaporizer 7 temperature reduces the most rapidly, and cold wind through air channel, is sent to cold room 1 from air outlet 13, then passed through by blower fan 15
Return air inlet 14 returns to the bin at vaporizer 3 place.Steam in cold room 1 can be taken away by this process, causes cold room 1
Humidity is the lowest, and in inventing, because being provided with moisturizing vaporizer 7, and its surface temperature is the lowest, is held open by moisturizing fan 6
Until cold room 1 stops refrigeration, the steam in wind path can be made to be deposited in moisturizing vaporizer 7 surface in a large number；Not only reduce
The cooling time of cold room 1, moreover it is possible to realize dynamically storing of cold room 1 wet；
When only other room refrigeration, the temperature of vaporizer 3 and moisturizing vaporizer 7 reduces simultaneously, now, and moisturizing fan 6
According to first a minute out of service, it is then turned on running the cycle of modes of b minute to compressor shutdown, thus realizes cold preservation
The cold moisturizing of benefit of room 1；The scope of a is 10 seconds～10 minutes；The scope of b is 10 seconds～10 minutes；
As shown in Figure 4, when the compressor is shut down, vaporizer 3 and moisturizing vaporizer 7 temperature slowly rise, by moisturizing vaporizer
Heater 9a and moisturizing fan 6 cooperating make defrosting water drip, the process of humidification is: moisturizing evaporator heater 9a is first
Open, be rapidly completed defrosting water drippage, after closing moisturizing evaporator heater 9a, according to judging whether level sensor 10 reaches
To limit value, if reaching limit value, the most only open moisturizing fan 6, if not up to, then water storage case heater 9b and moisturizing fan 6
Open simultaneously, but moisturizing fan 6 working time is longer than water storage case heater 9b working time, and water storage case heater 9b heating
Finish time is later than moisturizing evaporator heater 9a, it is achieved rapid evaporation defrost aquation and the purpose that is humidified.
As it is shown in figure 5, when refrigerator system defrost, the temperature of vaporizer 3 can rise rapidly, by moisturizing evaporator heater 9a
The process make defrosting water drippage with moisturizing fan 6 cooperating, being humidified is: opens moisturizing evaporator heater 9a and runs, until
Moisturizing evaporator heater 9a is closed after till during defrosting water is dropped into water storage case 11 completely on moisturizing vaporizer 7；Utilize water level
Sensor 10 judges whether the water level in water storage case 11 reaches limit value, if reaching limit value, the most only opening moisturizing fan 6 and running,
Avoid dry combustion method；Otherwise, open water storage case heater 9b to run with moisturizing fan 6 simultaneously；And moisturizing fan 6 long operational time
The operation time in water storage case heater 9b；Water storage case heater 9b heating finish time is later than moisturizing evaporator heater 9a,
Fast defrosting water speed is evaporated, thus realizes the humidification to cold room 1.
