Abstract
The utility model discloses a defrosting mechanism of dual temperature control direct cooling refrigerator. The utility model overcomes the defect of removing frost too slowly in present refrigerator, and has the advantages of cutting down defrosting time and accelerating the defrosting process. The utility model is provided with a compressor which is connected with a condenser, an electromagnetic valve, a freezing evaporator, and a refrigerating evaporator by a vent pipe. The utility model is characterized in that the vent pipe is provided with a straight tee; the other pipe C is connected with the inlet of the freezing evaporator by the electromagnetic valve after being connected with the straight tee.
Description
The utility model relates to a kind of defrost mechanism, relates in particular to a kind of defrost mechanism of double temperature double control direct cooling refrigerator.
Direct cooling refrigerator used in everyday has two kinds of two warm single controlleds and double temperature double control formulas by the control mode branch.Because double temperature double control formula temperature control is accurate, use more and more generally, but its defrosting still needs the user to carry out artificial defrosting.When artificial defrosting, need to root out the long-pending frost of evaporator surface gently or allow the temperature inside the box go up naturally to melt long-pending frost with the defrosting shovel, because the temperature inside the box is low, the frost layer of evaporator surface is thicker, which kind of mode all need take a long time, the food that is placed on the outside easily melts through long-time back, thereby influence food quality, be unfavorable for people's health.
The purpose of this utility model is exactly in order to solve the slow shortcoming of current refrigerator defrosting, a kind of shortening defrosting time that has to be provided, accelerating the double temperature double control direct cooling refrigerator defrost mechanism of advantages such as defrost process.
For achieving the above object, the utility model adopts following technical scheme: a kind of double temperature double control direct cooling refrigerator defrost mechanism, it has compressor, respectively by blast pipe successively with condenser and magnetic valve, refrigerating evaporator and refrigeration evaporator link, and it is characterized in that: controlled pipeline c is linked together the inlet of refrigerating evaporator with the blast pipe that directly links with compressor.Described controlled pipeline c one end is connected in the threeway, and this threeway is on the blast pipe between compressor and condenser, and the other end links to each other with the inlet of refrigerating evaporator through magnetic valve.The coil M on control a, b road and the coil N on control c road are arranged on the magnetic valve, and a road connects with refrigeration evaporator, and the b road connects with refrigerating evaporator.
Owing to adopted technique scheme,, made it quicken defrosting during defrosting by thermal medium by a controlled pipeline c without condenser, thereby shortened defrosting time, quickened defrost process, with existing similar refrigerator structure compared novelty, time saving and energy saving, be particularly suitable for the user and use.
The utility model is described in further detail below in conjunction with accompanying drawing and embodiment.
Fig. 1 is a structural representation of the present utility model.
Connect a threeway 3 on the blast pipe 2 of 4 of compressor 1 and condensers, controlled pipeline c one end is connected in this threeway 3, and the other end directly links to each other with the inlet of refrigerating evaporator 7 by magnetic valve 5 backs.Two coil M, N are arranged on the magnetic valve 5, and the N coil is controlled controlled pipeline c, in that coil N is not charged at ordinary times, make that the c road is obstructed, control the break-make on a, b road according to the power on/off of M coil, a road connects with refrigeration evaporator 6, b road and refrigerating evaporator 7 link, with the flow direction of control cold-producing medium.When needs defrost, open chamber door, with drawer and the concentrated place, cool place that transfers to of food.Closed defrost switch, the N coil of magnetic valve 5 is charged, logical b road, c road is disconnected, simultaneously temperature controller is transferred to the coldest position, compressor operating, the high-temperature medium of discharge directly arrives refrigerating evaporator through the c road of magnetic valve 5, melts the long-pending frost of evaporator surface fast with extraneous air, so accelerated white thawing speed greatly, need not artificial with rooting out frost.Though a road is also logical during defrosting, owing to have capillary, pipe resistance to be far longer than the c road, few by the cold-producing medium on a road, do not influence defrosting.
