The refrigerator is provided with an evaporator, when the evaporator is stopped or is heated by a defrosting heater, frost adhered to the surface of the evaporator can be melted, and defrosting water is discharged through a drain pipe. The ambient temperature of the evaporator is usually low, so that the inside of the drain pipe is easy to freeze, the problem of ice blockage of the drain pipe is caused, the refrigeration performance of the refrigerator is further affected, and even equipment is damaged.

In the related art, an antifreezing plug made of a section of metal material is wound on the outer wall of a condensing pipe or a dew removing pipe, and one end of the antifreezing plug is wound on the outer wall of a drain pipe. In the refrigerating process of the refrigerator, the condensing pipe or the dew removing pipe belongs to a heating component, the temperature is high, and the antifreezing plug transfers heat of the heating component to the drain pipe, so that the temperature of the drain pipe is increased, and the phenomenon of ice blockage of the drain pipe is prevented.

The anti-freezing plug is a metal product similar to an iron wire, and has certain heat conductivity, but when the drain pipe is frozen seriously, the deicing speed of the anti-freezing plug is slower, and the deicing effect is poor.

The embodiment of the disclosure provides a refrigerator, which can effectively reduce the problem of ice blockage of a drain pipe.

As shown in fig. 1 and 2, the embodiment of the present disclosure provides a refrigerator including an evaporator 100, a drain pipe 200 and a condenser 300, the drain pipe 200 being provided below the evaporator 100 for receiving and discharging defrost water of the evaporator 100; the condenser 300 includes a condenser main body 310 and heat exchange tubes 320, the condenser main body 310 includes condenser tubes 311 and fins, and the condenser tubes 311 are provided to the fins.

The refrigerator further includes a compressor 600, and the compressor 600, the evaporator 100, and the condenser 300 are in communication. The heat exchange tube 320 is communicated with the condenser tube 311, and the refrigerant flowing out of the compressor 600 flows in the heat exchange tube 320, the condenser tube 311 and the evaporator 100, thereby realizing the refrigeration of the refrigerator.

The heat exchange pipe 320 corresponds to the drain pipe 200 for exchanging heat with the drain pipe 200.

The refrigeration cycle system of the refrigerator generally comprises a compressor 600, a condenser 300, a dry filter 800, a capillary tube 900, an evaporator 100 and other component structures which are communicated through refrigerant pipes, and the working process of the refrigeration cycle system comprises: compression, condensation, throttling and evaporation processes. Specifically, the compression process is: after the refrigerator power line is plugged in, the compressor 600 starts to work under the condition that the refrigerator has a refrigerating requirement, the low-temperature and low-pressure refrigerant from the evaporator 100 is sucked by the compressor 600, compressed into high-temperature and high-pressure superheated gas in the cylinder of the compressor 600 and then discharged into the condenser 300, and specifically enters the condenser pipeline 311 and the heat exchange tube 320. The condensation process is as follows: the high temperature and high pressure refrigerant gas is cooled by the condenser 300, the temperature is continuously reduced, the refrigerant gas is gradually cooled into normal temperature and high pressure saturated vapor, the refrigerant gas is further cooled into saturated liquid, the temperature is not reduced any more, and the pressure of the refrigerant is almost unchanged in the whole condensation process. The throttling process is as follows: the condensed saturated liquid of the refrigerant flows into the capillary tube 900 after the moisture and impurities are filtered by the dry filter 800, and the refrigerant is throttled and depressurized by the capillary tube 900 to be in a normal-temperature and low-pressure state. The evaporation process is as follows: the refrigerant at normal temperature and low pressure enters the evaporator 100 to start absorbing heat for vaporization, so that the temperature of the evaporator 100 and the surrounding temperature are reduced, the refrigeration chamber is refrigerated, and the refrigerant is changed into low-temperature and low-pressure gas. The refrigerant discharged from the evaporator 100 is returned to the compressor 600 again, and the above process is repeated, and the heat in the refrigerator is transferred to the air outside the refrigerator by the energy conversion according to the state change of the refrigerant, thereby realizing the refrigerating cycle of the refrigerator.

When the refrigerant evaporates in the evaporator 100, the refrigerant absorbs the ambient heat, so that the ambient temperature of the evaporator 100 is reduced, the food is cooled to achieve the purpose of refrigeration and fresh-keeping, and frost is formed on the surface of the evaporator 100 due to the temperature difference with the ambient air.

The drain pipe 200 is disposed below the evaporator 100, when the evaporator 100 stops cooling, the frost on the surface of the evaporator 100 melts, and the defrost water flows out of the drain pipe 200, but due to the low temperature in the tank, the defrost water may frost or freeze in the drain pipe 200 during the draining process, eventually causing the drain pipe 200 to be blocked.

The condenser pipeline 311 is arranged on a side plate of the refrigerator, and radiates high-temperature and high-pressure refrigerant in the condensation process, part of the pipeline of the condenser pipeline 311 extends out of the side plate of the refrigerator to the drain pipe 200 to form a heat exchange pipe 320, the heat exchange pipe 320 corresponds to the drain pipe 200, and the heat exchange pipe 320 is communicated with the condenser pipeline 311.

When the refrigerator is refrigerating, high-temperature and high-pressure gaseous refrigerant discharged from the compressor 600 enters the condenser pipeline 311 through the heat exchange tube 320, the heat exchange tube 320 is arranged corresponding to the drain pipe 200, and the high-temperature and high-pressure refrigerant in the heat exchange tube 320 is used for transferring heat to the drain pipe 200, so that the problem of ice blockage caused by icing in the drain pipe 200 can be effectively solved while the energy consumption is not increased.

In addition, the refrigerant with high temperature and high pressure firstly passes through the heat exchange tube 320 and then enters the condenser pipeline 311, so that the temperature of the refrigerant in the heat exchange tube 320 is higher than that of the refrigerant in the condenser pipeline 311, on one hand, the heating effect of the heat exchange tube 320 on the drain pipe 200 can be improved, on the other hand, the temperature of the defrosting water in the drain pipe 200 is reduced, the cold energy can be transferred to the heat exchange tube 320, the heat exchange tube 320 is communicated with the condenser pipeline 311, and the efficiency of the condenser 300 is improved.

It will be appreciated that the high temperature and pressure refrigerant exiting the compressor 600 may also flow through the condenser tube 311 before entering the heat exchange tube 320, i.e., the heat exchange tube 320 is connected to the side of the condenser tube 311 facing away from the air outlet of the compressor 600.

Optionally, the heat exchange pipe 320 includes, corresponding to the drain pipe 200: the heat exchange tube 320 is attached to the outer wall of the drain pipe 200; or the heat exchange tube 320 is connected with the drain pipe 200 through a heat conducting medium, wherein the heat conducting medium can be an iron wire, a copper wire or other substances which are easy to conduct heat; or the heat exchange tube 320 is wound around the outer wall of the drain pipe 200.

Optionally, the heat exchange tube 320 is attached to the outer wall of the drain tube 200.

As shown in conjunction with fig. 2 and 3, optionally, the heat exchange tube 320 is attached to the outer wall of the drain pipe 200, including: the heat exchange tube 320 is wound around the outer wall of the drain pipe 200 and is in direct contact with the outer wall of the drain pipe 200; or the heat exchange tube 320 and the drain pipe 200 are vertically arranged, and the outer wall of the heat exchange tube 320 is mutually attached to the outer wall of the drain pipe 200.

Through laminating heat exchange tube 320 in the outer wall of drain pipe 200, in refrigerator refrigeration process, the high temperature, high pressure refrigerant of compressor 600 discharge, in condenser pipeline 311 is got into to heat exchange tube 320, and high temperature refrigerant carries out the heat exchange with drain pipe 200 in the heat exchange tube 320 to for drain pipe 200 transfer heat, effectively solve the stifled problem of ice of drain pipe 200.

Alternatively, the heat exchange tube 320 is wound around the outer wall of the drain pipe 200 and extends along the length direction of the drain pipe 200.

The heat exchange tube 320 is spirally wound on the outer wall of the drain pipe 200 along the length direction of the drain pipe 200, the spiral winding pitch can be set according to the actual icing condition of the drain pipe 200, and the total length of the heat exchange tube 320 can be adjusted according to the total length of the drain pipe 200, so that the heat exchange tube 320 can be wound and wrapped at the icing position of the drain pipe 200.

Alternatively, the cross-sectional shape of the heat exchange tube 320 may be circular, elliptical, square, or the like, and in this embodiment, the cross-sectional shape of the heat exchange tube 320 is set to be elliptical.

The drain pipe 200 is generally cylindrical, and the cross-section of the heat exchange tube 320 is elliptical, so that the contact area between the heat exchange tube 320 and the drain pipe 200 can be increased, and the heat exchange between the heat exchange tube 320 and the drain pipe 200 is facilitated. And the cross-sectional shape of the heat exchange tube 320 is set to be elliptical so as not to affect the flow of the refrigerant in the heat exchange tube 320.

The heat exchange tube 320 is arranged on the outer wall of the drain pipe 200 in a winding manner, so that the contact area between the heat exchange tube 320 and the drain pipe 200 can be increased, and the problem that the drain pipe 200 is frozen and ice blockage occurs can be solved. The heat exchange tube 320 is a part of the pipeline extending from the condenser pipeline 311, which is equivalent to directly winding the part of the condenser pipeline 311 to the outer wall of the drain pipe 200, has simple structure and easy implementation, and utilizes the self heat of the condenser 300 to heat the drain pipe 200, thereby reducing energy loss.

As shown in connection with fig. 3, alternatively, the heat exchange tube 320 has a greater winding density at the first end 210 of the drain tube 200 than at the second end 220 of the drain tube, wherein the first end is spaced from the evaporator 100 less than the second end, e.g., the evaporator 100 is positioned above the drain tube 200, the first end 210 is the top end of the drain tube 200, and the second end 220 is the bottom end of the drain tube 200.

The drain pipe 200 is generally provided between the evaporator 100 and the compressor 600, and the evaporator 100 absorbs ambient heat mainly by evaporating a refrigerant during the cooling process of the refrigerator, thereby reducing the ambient temperature of the evaporator 100. And the compressor 600 compresses a refrigerant in a refrigerating process of the refrigerator to generate high-temperature, high-pressure gas, and the temperature around the compressor 600 rises. Thus, at a low temperature where the drain pipe 200 is near the first end 210 of the evaporator 100, the drain pipe 200 is susceptible to ice formation, and at a higher temperature where the drain pipe 200 is near the second end 220 of the compressor 600, the drain pipe 200 is less susceptible to ice formation.

The winding density represents the tightness in which the heat exchange tube 320 is wound around the outer wall of the drain pipe 200. The greater the winding density, the smaller the pitch of the spiral winding, the more tightly the heat exchange tube 320 is wound around the outer wall of the drain pipe 200; conversely, the smaller the winding density, the greater the pitch of the spiral winding, and the more sparsely the heat exchange tube 320 is wound around the outer wall of the drain pipe 200.

The winding density of the heat exchange tube 320 at the first end 210 is greater than that at the second end 220, so that the contact area between a section of the drain tube 200 which is easy to freeze and the heat exchange tube 320 is larger, the heat transfer between the heat exchange tube 320 and the drain tube 200 is accelerated, and the problem of ice blockage caused by icing inside the drain tube 200 is reduced. The heat exchange tube 320 is wound at the second end 220 at a sparse position, so that the total length of the heat exchange tube 320 can be reduced, and the cost is saved.

Optionally, the refrigerator further comprises a water pan 400 and an evaporation pan 500, wherein a water outlet 410 is arranged at the bottom of the water pan 400, and the first end 210 of the water drain pipe is communicated with the water outlet 410; the second end 220 of the drain pipe is arranged on the evaporating dish 500; wherein the flow direction of the refrigerant in the heat exchange tube 320 is from the evaporation pan 500 to the drain port 410.

Optionally, the water pan 400 is disposed at the bottom of the evaporator 100, the water pan 400 is formed by surrounding an inclined plane formed by inclining the periphery of the bottom end of the evaporator 100 toward the center, and the water pan 400 is funnel-shaped. The water pan 400 is used for receiving condensed water or defrost water generated by the evaporator 100.

Alternatively, the evaporation pan 500 is provided at the top of the compressor 600, and the water in the evaporation pan 500 is evaporated using the heat generated from the compressor 600.

The refrigerator generates condensation water due to cold and heat exchange in the refrigerator during operation, and the refrigerator periodically defrost to generate frost water, wherein the condensation water and the frost water are discharged into the evaporation pan 500 through the drain pipe 200, wherein the drain pipe first end 210 is communicated with the drain outlet 410, and the drain pipe second end 220 is arranged in the evaporation pan 500 to guide the frost water from the water receiving tray 400 into the evaporation pan 500. In order to avoid flooding the water collected in the evaporation pan 500, it is common practice to heat the water of the evaporation pan 500 to accelerate evaporation. The evaporation pan 500 is disposed at the top of the compressor 600, and water in the evaporation pan 500 is evaporated by heat generated when the compressor 600 is operated.

Optionally, the heat exchange tube 320 has a smaller winding radius at the drain pipe first end 210 than at the drain pipe second end 220, wherein the first end is located a smaller distance from the evaporator 100 than the second end.

The winding radius of the heat exchange tube 320 at the drain pipe 200 refers to the distance between the heat exchange tube 320 and the drain pipe 200 when the heat exchange tube 320 is wound around the outer wall of the drain pipe 200, and the winding radius of the heat exchange tube 320 at the first end 210 of the drain pipe is smaller than the winding radius at the second end 220 of the drain pipe, so that the drain pipe 200 is close to a section of the evaporator 100 which is easy to freeze, and the heat exchange tube 320 is more attached to the drain pipe 200; the heat exchange tube 320 increases in winding radius at the drain pipe second end 220, and the section of the drain pipe 200 is less prone to ice formation due to proximity to the compressor 600. The winding radius of the heat exchange tube 320 at the drain pipe second end 220 increases, so that the coverage area of the heat exchange tube 320 above the evaporation pan 500 increases, and the heat generated by the compressor 600 and the heat generated by the heat exchange tube 320 jointly act on the evaporation pan 500, which is beneficial to accelerating the evaporation of water in the evaporation pan 500.

The flow direction of the refrigerant in the heat exchange tube 320 is from the evaporation pan 500 to the drain port 410, so that the high temperature refrigerant discharged from the compressor 600 flows to the upper side of the evaporation pan 500 to accelerate the evaporation of water in the evaporation pan 500. And then flows along the heat exchange pipe 320 toward the drain port 410 to transfer heat to the drain pipe 200.

In some embodiments, the heat exchange tube 320 is made of metal.

Alternatively, the heat exchange tube 320 is made of galvanized steel tube, and the galvanized steel tube is a welded steel tube with a hot dip plating or electrogalvanizing layer on the surface. The galvanization can increase the corrosion resistance of the steel pipe and prolong the service life. The galvanized pipe has wide application range and can be used as an oil well pipe, an oil delivery pipe, an oil heater, a condensation cooler and the like of chemical coking equipment in petroleum industry, in particular in offshore oil fields.

The galvanized steel pipe has good strength and ductility so that it is easily extended without breaking under the external force, thereby facilitating the winding of the heat exchange pipe 320 around the outer wall of the drain pipe 200.

The heat conductivity of the galvanized steel pipe is as high as 16W/(MK), so that heat is easy to be dissipated, and the heat exchange between the heat exchange pipe 320 and the drain pipe 200 is facilitated.

Optionally, the heat exchange tube 320 is made of copper tube or aluminum tube.

As shown in connection with fig. 1, the refrigerator optionally further includes a compressor 600, and the heat exchange tube 320 is communicated between the condenser tube 311 and the compressor 600.

In the refrigerating process of the refrigerator, the compressor 600 discharges high-temperature and high-pressure refrigerant, and the heat exchange tube 320 is communicated between the condenser tube 311 and the compressor 600, so that the high-temperature and high-pressure refrigerant flows through the heat exchange tube 320 and then flows to the condenser tube 311, thereby transferring heat to the drain tube 200 by using the high-temperature refrigerant.

As shown in fig. 2, optionally, a compressor compartment 610 is provided in the refrigerator, a compressor 600 is provided in the compressor compartment 610, an evaporator 100 is provided outside the compressor compartment 610, and a heat exchange tube 320 is provided in the compressor compartment 610.

The evaporator 100 absorbs ambient heat during the refrigerator cooling process, causing the temperature around the evaporator 100 to drop. The compressor 600 compresses the refrigerant in the refrigerating process of the refrigerator, discharges the high-temperature and high-pressure refrigerant, the temperature around the compressor 600 rises, the heat generated by the heat exchange tube 320 and the compressor 600 is widely spread in the compressor 610 by commonly arranging the heat exchange tube 320 and the compressor 600 in the compressor 610, the water discharge pipe 200 is favorably used for deicing, the evaporation dish 500 is favorably used for evaporating the defrosting water, and the heat can not influence the refrigerating of the evaporator 100.

Optionally, heat exchange tubes 320 are connected in series or parallel with condenser tubes 311.

Referring to FIG. 4, the heat exchange tube 320 is connected in parallel with the condenser tube 311, and a control valve 330 is provided in the parallel branch.

When the water discharge pipe 200 is ice-blocked, the control valve 330 is opened, and the heat exchange pipe 320 is connected in parallel with the condenser pipe 311, and the refrigerant flows out of the compressor 600, and one part flows to the heat exchange pipe 320, and the other part flows to the condenser pipe 311, and finally meets. When the heat exchange tube 200 is not frozen, the control valve 330 is closed, and the heat exchange tube 320 is connected in series with the condenser tube 311, and the refrigerant flows from the condenser tube 311 to the evaporator 100.

By providing the control valve 330, the heat exchange tube 320 and the condenser tube 311 can be controlled in series or parallel, and when the control valve 330 is closed, the refrigerant does not flow through the heat exchange tube 320, thereby avoiding the repeated heating of the heat exchange tube 320.

Optionally, the refrigerator further includes a limiting member 700, where the limiting member 700 is disposed on the heat exchange tube 320 and the limiting member 700 is disposed on the heat exchange tube 320, so as to realize positioning of the heat exchange tube 320 on the drain pipe.

Optionally, the limiting member 700 includes two limiting rings, the two limiting rings are sleeved on the outer wall of the drain pipe, and the heat exchange tube 320 is arranged between the two limiting rings.

By arranging the limiting piece 700, the heat exchange tube 320 can be limited on the drain pipe, and displacement of the heat exchange tube 320 due to loose winding of the drain pipe 200 is prevented.

With reference to fig. 1 and fig. 2, the refrigerator provided in the embodiment of the disclosure may achieve the following technical effects: the refrigerator includes an evaporator 100, a drain pipe 200, and a condenser 300, the drain pipe 200 being provided below the evaporator 100 for discharging defrost water of the evaporator 100.

In addition, the heat exchange tube 320 is a part of the extended condenser tube 311, which is equivalent to directly winding the part of the condenser tube 311 to the outer wall of the drain pipe 200, and heating the drain pipe 200, so that no additional energy consumption of the refrigerator is increased.
