[detailed description of the invention]
Below in conjunction with accompanying drawing 1-2, the utility model embodiment is described in detail.
The present embodiment provides the two-door refrigerator 10 of downward swing door on, and this refrigerator 10 comprises refrigerating chamber 11 and is positioned at the refrigerating chamber 12 below refrigerating chamber 11, is separated between refrigerating chamber 10 and refrigerating chamber 11 by an adiabatic wall 13.
Arrange refrigerating chamber osculum 5 at refrigerating chamber rear wall 14 and near the position of refrigerating chamber diapire 7, the condensed water on refrigerating chamber rear wall 14 is collected into refrigerating chamber osculum 5 and discharges via refrigerating chamber drainpipe 6.
The evaporimeter (not shown) that low-temperature receiver is provided is provided with in refrigerating chamber 12, the refrigerating chamber osculum 17 of the defrosting water for collecting evaporimeter is provided with, through being discharged by refrigerating chamber drainpipe 21 after the defrosting water of collection enters refrigerating chamber osculum 17 in the below of evaporimeter.
Fig. 2 can find out, the water exit end of refrigerating chamber drainpipe 21 is the siphon pipe of U-shaped, can prevent the cool air leakage in refrigerating chamber and stop extraneous hot-air to enter refrigerating chamber 10.The water that refrigerating chamber drainpipe 21 is discharged can directly drain into refrigerator outside, or drains into the drip tray of the Machine Room being arranged in refrigerator, by the heat of vaporization on condenser or compressor.
When the door that user opens refrigerating chamber 12 takes article, have a large amount of hot-airs and enter refrigerating chamber 12 from the external world, this part hot-air is cooled in refrigerating chamber 12, the principle of expanding with heat and contract with cold, the volume of hot-air reduces, pressure in refrigerating chamber 12 is reduced, and refrigerating chamber pressure drop is low to moderate that I haven't seen you for ages brings two kinds of impacts: 1. the pressure differential of the both sides of the door of refrigerating chamber 12 increases, and user opens the door needs larger power; 2. because pressure in refrigerating chamber 12 reduces, water in siphon pipe, under the effect of atmospheric pressure, can flow to refrigerating chamber 12 direction, although pressure difference is difficult to make the water in siphon pipe be back in refrigerating chamber, but, noise that is obvious and that allow user easily discover during flowing, can be produced.Based on above-mentioned adverse influence, the present embodiment is provided with the air inlet pipe 19 of supplied gas circulation between refrigerating chamber 11 and refrigerating chamber 12, for balancing the pressure between refrigerating chamber 11 and refrigerating chamber 12.
The rear wall 14 of refrigerating chamber 11 is provided with steam vent 16, blast pipe 19 is connected on refrigerating chamber drainpipe 21 by three-way connection 1, thus make to be communicated with between refrigerating chamber steam vent 16 and refrigerating chamber osculum 17, gas can flow freely between refrigerating chamber 11 and refrigerating chamber 12.The size of steam vent 16 is greater than the size of refrigerating chamber osculum 5.
The position in the vertical direction of steam vent 16 is higher than refrigerating chamber osculum 5, steam vent 16 arranges vent cap 2, vent cap 2 has multiple aperture supplied gas to pass through, in order to avoid the condensed water on refrigerating chamber rear wall 14 enters steam vent 16, multiple muscle for water guide is set on the surface of vent cap 2.
Because in refrigerating chamber 11, storing food easily produces peculiar smell, refrigerating chamber 12 is entered in order to prevent peculiar smell, gas-filtering device 18 is set in blast pipe 19, the carbon bag that gas-filtering device 18 can adopt adsorptivity stronger, carbon bag, except the peculiar smell in adsorbed gas, also can adsorb in the gas entered in blast pipe 19 a small amount of aqueous vapor contained.Gas-filtering device 18 is arranged on the side near refrigerating chamber steam vent 16 in blast pipe 19, and gas-filtering device 18 can be avoided to absorb aqueous vapor and produce condensation.
Refrigerating chamber drainpipe 21 is divided into two parts by three-way connection 1, and Part I 3 is one section between three-way connection 1 and refrigerating chamber osculum 17, and Part II 20 is the part that the refrigerating chamber drainpipe 21 of three-way connection 1 connection is left.Because the Part I 3 of refrigerating chamber drainpipe 21 is near refrigerating chamber 12, there is condensation herein to prevent the water overlayed on the inwall of refrigerating chamber drainpipe 21 and produce blocking, being wound around heater strip at the outer wall of the Part I 3 of refrigerating chamber drainpipe 21 and periodically heating.
