Background technology
In freezer runs, due to cold wind surface frosting, after needing to run a period of time, cold wind defrosting out of service.
Current air-cooler, defrosting process is heated by the electric heater in evaporation coil.In this process, the hot-air produced directly is discharged in freezer and goes, and makes temperature of ice house produce fluctuation, causes electric heater heat effectively not utilize.The temperature fluctuation how reduced in defrosting process is that current freezer technical field needs one of technical barrier solved.The patent No. is 201420394004, invention and created name for " a kind of energy-saving air-conditioner " patent document discloses a kind of air-cooler with the fan housing preventing high temperature air in body excessive; The patent No. is 201420067166, invention and created name for " a kind of Novel belt water curtain air-cooler " patent document discloses a kind of air-cooler with rear portion water screen generator, anterior water screen generator; The patent No. is 201420015964, invention and created name is " closed defrosting air-cooler " patent document discloses the air-cooler that a kind of air inlet at air-cooler and air outlet place are separately installed with air-valve; The one that patent document discloses that patent is well 201210530047, invention and created name is " the differential defroster of freezer evaporator in air cooler " has left and right plenum chamber, and two plenum chambers are respectively equipped with the defrosting device of pressure reduction blower fan; The one that patent document discloses that the patent No. is 200910304362, invention and created name is " a kind of energy-saving type air cooler " is respectively arranged with air inlet and air outlet, be provided with the air inlet deep bead of closed rear enclosed air inlet in air inlet, be provided with the air-cooler of the air outlet deep bead of closed rear enclosed air outlet at air outlet place.Particularly patent " the differential defroster of freezer evaporator in air cooler " and " a kind of energy-saving type air cooler " are that the storehouse temperature fluctuation solving defrosting provides good thinking.But the technical scheme of " the differential defroster of freezer evaporator in air cooler " will combine with cold storage locker body, complex structure, control inconvenient; Then efficiency is low for the technical scheme of " a kind of energy-saving type air cooler ", and can produce superheating phenomenon.
Utility model content
The purpose of this utility model is the technological deficiency for existing in prior art, and provides a kind of fluctuation that can reduce temperature of ice house, can realize again energy-conservation interior defrosting air-cooler.
The technical scheme adopted for realizing the purpose of this utility model is:
Defrosting air-cooler in a kind of, it is characterized in that, comprise housing, described housing two ends are separately installed with inlet air door and air-out air door, described enclosure interior is provided with evaporation coil and blower fan, between described evaporation coil and described inlet air door, electric heater is installed, between described evaporation coil and described electric heater, forms return air plenum chamber, between described evaporation coil and described blower fan, form air supply plenum chamber; The bottom of described housing is provided with circulation air path, and the described circulation air path between described blower fan and air-out air door is provided with air intake air-valve, and the described circulation air path between described inlet air door and electric heater is provided with air-out air-valve; Described evaporation coil bottom is provided with water-collecting tray, and described water-collecting tray is connected with drainpipe; When air-cooler normally runs, described air intake air-valve and air-out air-valve are in closed condition, and described electric heater does not work, and described inlet air door and air-out air door are opened; When needing defrosting, described inlet air door and air-out air door are closed, and described air intake air-valve and air-out air-valve are opened, electric heater work, and under the effect of blower fan, air is at circulation air path and housing Inner eycle.
Compared with prior art, the beneficial effects of the utility model are:
1, air-cooler of the present utility model is by rational structural design, the external outside at evaporation coil of electric heater, when air-cooler normally runs, air intake air-valve and air-out air-valve are in closed condition, electric heater does not work, and inlet air door and air-out air door are opened, and needs the air of cooling to be entered by air door 2 under the effect of blower fan, by return air plenum chamber, evaporation coil, air supply plenum chamber and air door 1, be sent to freezer.When needing defrosting, inlet air door and air-out air door are closed, and air intake air-valve and air-out air-valve are opened, electric heater work, and under the effect of blower fan, the air in air-cooler is at circulation air path Inner eycle.Use air-cooler of the present utility model, temperature fluctuation during freezer defrosting can be reduced.And, utilize the air of flowing to carry out defrosting, reach energy-conservation object.And structure is simple, and the thermal efficiency is low, can not produce superheating phenomenon.
2, devise return air plenum chamber in air-cooler of the present utility model, can ensure that return air field is even.
3, devise air channel in air-cooler of the present utility model, defrosting hot blast at blower fan Inner eycle, can make defrosting hot blast not enter freezer by air channel like this, and reduce temperature of ice house fluctuation, heat concentrates in blower fan simultaneously, and defrosting efficiency is high.
Accompanying drawing explanation
Figure 1 shows that the structural representation of defrosting air-cooler in the utility model.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
In the utility model, the structural representation of defrosting air-cooler as shown in Figure 1, comprise housing, described housing two ends are separately installed with inlet air door 12 and air-out air door 1, described enclosure interior is provided with evaporation coil 4 and blower fan 2, between described evaporation coil 4 and described inlet air door 12, electric heater 6 is installed, form return air plenum chamber 5 between described evaporation coil 4 and described electric heater 6, between described evaporation coil 4 and described blower fan 2, form air supply plenum chamber 3.The bottom of described housing is provided with circulation air path 8, and the described circulation air path between described blower fan 2 and air-out air door 1 is provided with air intake air-valve 7, and the described circulation air path between described inlet air door 12 and electric heater 5 is provided with air-out air-valve 11.Described evaporation coil bottom is provided with water-collecting tray 9, and described water-collecting tray 9 is connected with drainpipe 10.When air-cooler normally runs, described air intake air-valve 7 and air-out air-valve 11 are in closed condition, described electric heater 6 does not work, described inlet air door 12 and air-out air door 1 are opened, the air of cooling is needed to enter enclosure interior by inlet air door 12 under the effect of blower fan, successively by return air plenum chamber 5, evaporation coil 4, air supply plenum chamber 3 and air-out air door 1, be sent to freezer.When needs defrosting, described inlet air door 12 and air-out air door 1 are closed, described air intake air-valve 7 and air-out air-valve 11 are opened, electric heater 4 works, under the effect of blower fan 2, air enters circulation air path 8 through air intake air-valve 7, then enters enclosure interior by air-out air-valve 11, hot-air after electric heater heating enters circulation air path through return air plenum chamber 5, evaporation coil 4, air supply plenum chamber 3, blower fan 2, air intake air-valve 7, successively at circulation air path and enclosure interior Inner eycle.Hot-air is realizing defrosting through evaporation coil.Water after thawing enters water-collecting tray, is flowed out by drainpipe.Under the effect at blower fan of the air of evaporation coil, so circulate, until defrosting terminates.
