The specific embodiment
Be below specific embodiment of the utility model by reference to the accompanying drawings, the technical solution of the utility model is further described, but the utility model be not limited to these embodiment.
As shown in Figure 1, the wet-film humidifying system of this wind cooling refrigerator comprises refrigerating chamber 1 and refrigerating chamber 6, be communicated with air inlet duct 5 between the two and form one-way circulation wind path with air-return duct 8, in refrigerating chamber 1, install blower fan 2 and heat exchanger 3, between refrigerating chamber 1 and refrigerating chamber 6, be also communicated with humidification branch road.
Air-return duct 8 becomes large channel design gradually for sectional area, makes thus return air wind speed increase and reduce with cross section.Air-return duct 8 upper bifurcations are communicated with the air inlet 10 of humidification branch road, and air inlet 10 is communicated with humidifying chamber, and humidifying chamber is communicated with refrigerating chamber 1 by the air outlet 14 being connected again.The crotch of air-return duct 8 arranges selector switch 9, and this selector switch 9, in the time being communicated with air-return duct 8, is blocked humidification branch road; Selector switch 9, in the time being communicated with humidification branch road, is blocked air-return duct 8.Selector switch 9 can be controlled the air force that returns through humidification branch road simultaneously, realizes the accurate control of humidity.
In humidifying chamber, install wet-membrane humidifier, wet-membrane humidifier comprises wet film body 11, and this wet film body 11 is high-density fiber material block.Drip tray 4 is installed in heat exchanger 3 belows in refrigerating chamber 1, and the bottom connection of this drip tray 4 arranges aqueduct.The top of wet film body 11 arranges trickle box 12, and trickle box 12 is communicated with aqueduct, the bottom even of trickle box 12 is offered some trickles hole, drip tray 4 is collected the defrosting water on heat exchanger 3 thus, deposit 12 li, trickle box in by aqueduct, and infiltrate through gradually and in wet film body 11, realize humidification and supply water by trickle hole under Action of Gravity Field.Discharge outlet 13 is also offered in the bottom of humidifying chamber, if defrosting water is too much, and wet film body 11 state that reaches capacity, unnecessary defrosting water can be discharged from discharge outlet 13.One side of wet film body 11 connects air inlet 10, and is covered with pore on wet film body 11, and all pore is communicated with air outlet 14.Pore is distributed in wet film body 11 inside, forms porous air exhausting structure, guarantees that return air air-flow fully contacts with wet film body 11, increases disengagement area.Current in wet film body 11 are vertically infiltration from top to bottom, and put down to by wet film body 11 on distinguished and admirable edge, distinguished and admirablely thus contacts with current are perpendicular, is beneficial to the distinguished and admirable moisture being evaporated that absorbs to greatest extent.
In refrigerating chamber 6, install humidity sensor 7, this humidity sensor 7 connects controller by circuit, and is electricly connected the selector switch 9 of air-return duct 8 crotches by controller, and controller also electricly connects the blower fan 2 in refrigerating chamber 1.By the humidity value in humidity sensor 7 moment detection refrigerating chamber 6, and detection signal is sent to controller, once detect that humidity value in refrigerating chamber 6 is lower than established standards, controller just controls selector switch 9 and cuts out air-return duct 8, be communicated with humidification branch road and carry out humidification.
Refrigerator is in the time of refrigeration work, and the starting stage, controller control blower fan 2 started without humidification, and blower fan 2 drives air-flow to be blown into refrigerating chamber 6 by refrigerating chamber 1 by air inlet duct 5 to freeze.Controller control selector switch 9 cuts out humidification branch road, is directly communicated with the air-return duct 8 between refrigerating chamber 6 and refrigerating chamber 1, and the distinguished and admirable humidification program of not passing through circulates between refrigerating chamber 1 and refrigerating chamber 6 thus.
When refrigerator stops after refrigeration, and experience a defrost periods, the drip tray 4 that is positioned at heat exchanger 3 belows has certain defrosting water, and defrosting water is collected into 12 li, trickle box by aqueduct, and is infiltrated through gradually and in wet film body 11, realized humidification and supply water by trickle hole under Action of Gravity Field.If the humidity that the humidity sensor 7 in refrigerating chamber 6 feeds back to controller is lower than setting value, controller control selector switch 9 cuts out air-return duct 8, be communicated with humidification branch road, simultaneously selector switch 9 can be controlled the air force that returns through humidification branch road, and in conjunction with the accurate controlled humidity of feedback signal of humidity sensor 7.Return air air-flow arrives humidifying chamber through air inlet 10, and entered by a side of wet film body 11, fully absorb transpiring moisture therein, thereby increase return air airflow humidity, finally enter refrigerating chamber 1 by air outlet 14 and carry out heat exchange effect with heat exchanger 3, drive and be blown into refrigerating chamber 6 by air inlet duct 5 and carry out humidification refrigeration by blower fan 2 again, in the kind of refrigeration cycle between refrigerating chamber 1 and refrigerating chamber 6, increase air-flow humidification program thus.
If the humidity that in refrigerating chamber 6, humidity sensor 7 feeds back reaches predetermined value, or refrigerator is while starting to freeze, and controller control selector switch 9 cuts out humidification branch road, is directly communicated with the air-return duct 8 between refrigerating chamber 6 and refrigerating chamber 1.
Specific embodiment described herein is only to the explanation for example of the utility model spirit.The utility model person of ordinary skill in the field can make various modifications or supplements or adopt similar mode to substitute described specific embodiment, but can't depart from spirit of the present utility model or surmount the defined scope of appended claims.
Although more used refrigerating chamber 1 herein; Blower fan 2; Heat exchanger 3; Drip tray 4; Air inlet duct 5; Refrigerating chamber 6; Humidity sensor 7; Air-return duct 8; Selector switch 9; Air inlet 10; Wet film body 11; Trickle box 12; Discharge outlet 13; Air outlet 14 terms such as grade, but do not get rid of the possibility that uses other term.Use these terms to be only used to describe more easily and explain essence of the present utility model; They are construed to any additional restriction is all contrary with the utility model spirit.
