Abstract

The utility model discloses a water-freeing arrangement for a refrigerator, comprising a water-freeing pipe used for draining water from the water outlet in the refrigerator into the compartment of a compressor and a water holding tray in the compartment of the compressor, characterized in that the water-freeing arrangement for a refrigerator also comprises a water-freeing appliance which is arranged at one end of the water-freeing pipe for storing water and forming liquid seal. Hot air can be effectively obstructed when entering the inner part of the refrigerator through the water-freeing pipe via the water-freeing arrangement for a refrigerator of the utility model, and the water-freeing arrangement for a refrigerator has the advantages of simple structure and low cost, and can be applied to refrigerators and cold cupboards with various types and formats.

Description

A kind of refrigerator drainage arrangement

Technical field

The utility model relates to the refrigerator technical field, more particularly, relates to a kind of refrigerator drainage arrangement.

Background technology

Refrigerator in the market, for the refrigerator evaporator wall of direct cooling refrigerator or the evaporimeter of wind cooling refrigerator, the defrost water that all adopts drainpipe will be attached on the evaporimeter or on the evaporimeter wall drains into outside the case.As shown in Figure 3, common design is the heat-insulation layer that drainpipe 1 is passed refrigerator, defrost water in the refrigerator is drained on the drip tray 3 in the compressor bin 4, and defrost water evaporates by high ambient temperature, or defrost water is drained into the condenser that is used in the compressor bin 4 in the cooled compressed cabin.This drainpipe generally is direct discharge, connects an elongated segment straight tube 5 in the exit of drainpipe, and directly draining is to the drip tray 3 of compressor bin bottom.The spacing that prolongs the end of straight tube 5 and drip tray 3 is very little, and this structure can directly cause drip tray with water first, avoids water to drench electrical part on the compressor; Second the principle that rises according to hot gas can prevent that too much hot-air from entering in the case from the draining mouth of pipe.Also some refrigerator has a kind of plastics or rubber plug 6 in the tip designs of drainpipe 1, and as shown in Figure 4, there is cross sections the lower end of plug, and defrost water can pass otch and flow in the drip tray, and its effect is to stop that hot-air enters in the refrigerator.

But, adopt the said structure design can bring many problems:

(1) though plug design is arranged, but still has the inside that hot-air directly enters to refrigerator, thereby can cause icing at the discharge outlet place of refrigerator inside, caliber is blocked, defrost water impeded drainage, even cause the obstruction of refrigerator inside discharge outlet, the phenomenon of ponding has influenced the normal use of refrigerator in the case.

(2) the part miniature organism can enter into refrigerator inside by drainpipe, has influenced health in the case.

(3) when refrigerator freezes, the pressure in the refrigerator reduces, and the air of outside can enter refrigerator by discharge outlet, and this air not only contains impurity, and can bring a part of heat in refrigerator, thereby causes energy loss.Equally, because drainpipe is in communication with the outside, do not form subnormal ambient in the refrigerator, in order to guarantee the refrigerator door good air-tightness, will improve the magnetic attraction of an envelope, obviously this is disadvantageous.

The utility model content

The technical problems to be solved in the utility model is, provides a kind of hot-air that can prevent to enter the drainage arrangement of refrigerator inside from drainpipe, to reduce the loss of refrigeration capacity of refrigerator, overcomes the deficiencies in the prior art.

For achieving the above object, a kind of refrigerator drainage arrangement is provided, comprise being used for water delivery port in the refrigerator case is drained into the drainpipe in the compressor bin, the drip tray in compressor bin, but also comprise water storage that is arranged on drainpipe one end and the drainage fixture that forms fluid-tight.

In the above-mentioned refrigerator drainage arrangement, described drainage fixture is one section bend pipe, and described bend pipe has the section of turning round that can form fluid-tight.

In the above-mentioned refrigerator drainage arrangement, described bend pipe is " U " shape.

In the above-mentioned refrigerator drainage arrangement, the tail end of described bend pipe is above drip tray or place in the drip tray.

In the above-mentioned refrigerator drainage arrangement, described drainpipe and bend pipe are integrally formed.

In the above-mentioned refrigerator drainage arrangement, be connected between described drainpipe and the bend pipe and be provided with sealing gasket.

The utility model compared with prior art has the following advantages and beneficial effect:

End at drainpipe connects the fluid-tight bend pipe, utilize water to seal the indoor and outdoor passage of refrigerator, thereby make hot-air can not enter into the inside of refrigerator, microorganism or uncleanly air can not enter into the inside of refrigerator, have prevented that effectively the inside and outside of air in drainage pipeline from ganging up.Stopped to have reduced loss of refrigeration capacity, solved the bad or unusual icing problem of defrost of refrigerator owing to hot-air enters the stifled phenomenon of discharge outlet ice that refrigerator inside causes from drainpipe.The utility model only need connect the preceding paragraph bend pipe at the drainpipe end just can reach desirable fluid-tight effect, has technology advantage simple, with low cost.

Fig. 2 is the structural representation of the utility model second embodiment;

Fig. 3 is the structural representation of existing refrigerator drainage arrangement;

Fig. 4 is another structural representation of existing refrigerator drainage arrangement.

The specific embodiment

The utility model is described in further detail below in conjunction with drawings and Examples.

As shown in Figure 1, label 1 expression drainpipe, it connects the discharge outlet of refrigerator inside and passes refrigerator heat-insulation layer (not shown), enter in the compressor bin 4 of refrigerator back, be used for the defrost water on evaporator surface or the refrigerator evaporator wall is drained in the drip tray 3 in the compressor bin, under the higher relatively environment of defrost water temperature in compressor bin, be evaporated to water vapour and enter in the surrounding air.Drip tray 3 is below compressor, and the refrigerator that has is designed to one with the supporting plate and the drip tray of fixing compressor, and supporting plate is designed to the disk-like structure that sink in the middle part, and defrost water directly is discharged on the sagging structure of supporting plate.End at drainpipe 1 connects one section upwards bend pipe 2 of the section of turning round, the section of turning round of bend pipe 2 is designed to " U " shape, drip tray 3 is pointed in the bending of pipeline section after the U-shaped section of turning round downwards, can be emitted on evaporation in the drip tray 3 after making defrost water by drainpipe 1, bend pipe 2.After freezer compartment of refrigerator evaporimeter or refrigerator evaporator defrost, defrost water is along drainpipe 1 bend pipe 2 of flowing through, and a part of water just is trapped in the U-shaped pipeline section, forms the water column of one section fluid-tight.Water column has intercepted the hot-air in the compressor bin, makes it can not pass drainpipe and enters refrigerator body inside.The structure of bend pipe 2 has guaranteed refrigerator through repeatedly defrost, has the fluid-tight water column all the time in the U-shaped pipeline section.

Referring to shown in Figure 2, at some drip tray 3 is placed on the refrigerator of compressor top, at the bend pipe 2 of the terminal connecting band U-shaped pipeline section of drainpipe 1, cause on the drip tray 3 at the end of U-shaped pipe.Drainpipe 1 can be integrally formed with bend pipe 2; Also can be to couple together by connected mode commonly used, as be threaded, socket etc., leak in order to prevent interface, can establish the sealing gasket (not shown) at the drainpipe 1 and the interface of bend pipe 2.
