The defrosting device has the characteristics of good defrosting effect, capability of keeping the cooling chamber at a lower temperature in the defrosting process and the like.
Description
Freezing, cold wind plant equipment that the utility model relates to.
Of the prior art freezing, the cold wind plant equipment, as the cooling calibrator in the shoemaking machinery, refrigerator in the food machinery, when defrosting in use for some time, the general employing with the extraneous condenser of connecting made " evaporimeter ", making " condenser " with the evaporimeter of the indoor connection of such apparatus cools defrosts, or defrost near placing above-mentioned evaporimeter with the part that compressor connects condenser pipe, though aforesaid way has evaporator surface and near the white effect of removing of bonding, the cooling indoor temperature sharply increases in defrost process but there is, and cooling chamber can not keep defectives such as lower temperature.
The objective of the invention is to solve the defective that exists in the above-mentioned Defrost technology, a kind of defrosting structure that keeps lower temperature in a kind of defrost process in the cooling chamber is provided.
Its technical solution is:
The utility model has main evaporator, main evaporator is furnished with compressor, condenser, main evaporator connects compressor by pipeline, compressor connects condenser by pipeline, condenser connects main evaporator by capillary or choke valve, and it also has a secondary evaporimeter, and this pair evaporimeter connects above-mentioned compressor by pipeline, main evaporator connects above-mentioned secondary evaporimeter by capillary or choke valve, and described pipeline is furnished with control valve.
Between above-mentioned main evaporator and the secondary evaporimeter thermal insulation layer is arranged.
Above-mentioned control valve has four way solenoid valve.
The device of promising its additional cold-producing medium of above-mentioned main evaporator.
The device of above-mentioned additional cold-producing medium has the liquid level display device.
The utility model is owing to adopt major and minor two evaporimeters, and when the cooling chamber operate as normal of freezing, cold wind equipment, main evaporator is as " evaporimeter " work, and secondary evaporimeter is not worked, and can realize the cooling, freezing to the cooling indoor article like this; In the time need removing to main evaporator surface and near bonding frost thereof, by adjusting above-mentioned control valve, secondary evaporimeter is as " evaporimeter ", main evaporator is as " condenser " work, aforementioned condenser shut down, because it is main, secondary evaporimeter is all only connected cooling chamber, the heat that so both can rely on main evaporator to distribute is removed main evaporator surface and near bonding frost thereof, can rely on the heat-absorbing action of secondary evaporimeter again, the intensification air that produces when main evaporator is defrosted as " condenser " cools off, help temperature constant control in the cooling chamber, make to keep lower temperature in the cooling chamber; In order to improve defrosting effect better, between main evaporator and secondary evaporimeter, can be provided with thermal insulation layer; Be provided with four way solenoid valve, be convenient to
Realization is controlled the said structure function conversion; The device of promising its additional cold-producing medium of main evaporator, the high-pressure refrigerant that exists in condenser, the liquid storage filling is in time replenished enter main evaporator, when defrosting, there are enough cold-producing mediums to participate in circulation, so that raising defrosting effect, the device that should replenish cold-producing medium has liquid to show mirror, be convenient to observe flowing into main evaporator cold-producing medium liquid measure situation, be convenient to remind and in time replenish cold-producing medium.
Below in conjunction with accompanying drawing the utility model is described in detail:
Figure is the utility model structural principle schematic diagram.
1 is compressor, and 2 is evaporating dish, and 3 is four-way electricity valve, and 4,15,20,21 is check valve, 5 is main condenser, and 6 is secondary condenser, and 7 is stop valve, 8 is device for drying and filtering, and 9 is the liquid level display device, and 10 are the refrigeration magnetic valve, 11 is choke valve, and 12 is main evaporator, and 13 is vapour liquid separator, 14 are the defrosting magnetic valve, and 16 is filter, and 17 is capillary, 18 is secondary evaporimeter, and 19 are defrosting fluid infusion magnetic valve, and 22 is fluid reservoir.
The utility model main evaporator 12 is furnished with compressor 1, main condenser 5, main evaporator 12 connects compressor 1 by pipeline, compressor 1 connects main condenser 5 by pipeline, main condenser 5 connects main evaporator 12 by capillary or choke valve (claiming expansion valve again) 11, in order to strengthen refrigeration, also can increase by a secondary condenser 6, it has a secondary evaporimeter 18, secondary evaporimeter 18 connects compressor 1 by pipeline, main evaporator 12 is by capillary * or choke valve (claiming expansion valve again) 17 auxiliary connection evaporimeters 18, described pipeline is furnished with above-mentioned some control valves, as four way solenoid valve 3, check valve 4,15,21, stop valve 7, refrigeration magnetic valve 10, defrosting magnetic valve 14 etc.When the cooling chamber operate as normal of this kind equipment, by regulating four way solenoid valve 3 etc., compressor 1, main evaporator 12, condenser 5,6, choke valve 11 etc. form refrigeration system, begin normal refrigeration work; When needing defrosting, regulate four way solenoid valve 3, shut off valve 10, open valve 14 etc., compressor 1, main evaporator 12, secondary evaporimeter 18, capillary 17 etc. form defrost system at this moment, begin defrosting work; Defrosting finishes, control valve 3, shut off valve 14, open valve 10 etc. again, and refrigeration system is started working; Said process moves repeatedly.Said process can be realized the operation that automaticity is higher by parts such as relevant electric, the temperature tests of configuration.18 in main evaporator 12 and secondary evaporimeter can have thermal insulation layer, so promptly are convenient to improve defrosting effect, are beneficial to again to keep balanced lower temperature in the cooling chamber.The device of main evaporator 12 promising its additional cold-producing mediums, this device can be made of following parts, the fluid reservoir 22 of auxiliary connection condenser or main condenser, stop valve 7, device for drying and filtering 8, liquid level display device 9, individual event valve 21, defrosting fluid infusion magnetic valve 19 etc., passing through liquid level display device 9 in defrost process observes when needing to replenish cold-producing medium, when open valve 7,19 reached an amount of for main evaporator 12 liquid make-up cold-producing mediums, shut off valve 7,19 can stop to replenish of cold-producing medium.
The utility model is applicable to the cooling chamber of small-type refrigeration appliances such as refrigeration machine, refrigerator.
