Description
Technical field
The present invention relates to a kind of refrigerator apparatus and using the structure refrigerator more particularly to a kind of refrigerator doorframe defrost
System and the refrigerator for using the system.
Background technology
The refrigerator produced and sold and used at present has two kinds of direct-cooling type and indirect-cooling, wherein indirect cooling refrigerator is also referred to as
" frost-free refrigerator ", for so-called " frostless " only frost layer knot in evaporator surface, people can't see frost layer in refrigerator inside.
And direct cooling refrigerator compares indirect cooling refrigerator apparent frosting, and mostly in freezing chamber.In the operational process of refrigerator, frost
Layer can hinder the heat exchange of evaporator surface, to influence the refrigerating efficiency of refrigerator.Frost layer is thicker, and refrigerating efficiency is poorer, therefore,
It is to improve an important channel of refrigerator performance that defrosting is periodically carried out to refrigerator.
There are two types of currently used Defrost methods：The first is traditional artificial method for defrosting or defrosting naturally:First,
Turn off refrigerator power supply, shifts all items in refrigerator；Then, refrigerator doors are opened, nature or artificial defrosting are carried out.Manually or certainly
So when defrosting, people usually use the removal frost layer such as hot water or defrosting shovel.But this Defrost method is unsatisfactory, first, entirely removing
White process takes longer, it is also possible to refrigerator be caused to damage；Second is that the water melted by hot water needs constantly to remove, accidentally,
One ground of flow, trouble；The too long preservation for being unfavorable for food and fresh-keeping third, chilled food delays outside refrigerator.
Second is electrical heating (heating wire, quartz ampoule heating etc.) Defrost method.The method defrosting efficiency of electric heated defrosting
Height, time-saving and efficiency.But it is a heater strip that the defrosting device in doorframe is installed in present civil refrigerator doorframe, but this sets
The existing defect of meter：First, heater strip increases equipment overall power, the efficiency of equipment is increased；Second is that this electrified heating silk
All have service life short and perishable；Third, if the heater strip being embedded in doorframe is broken replacement inconvenience.
So both Defrost methods all come with some shortcomings, all there is room for improvement.
Invention content
Technical problem to be solved by the present invention lies in provide a kind of defrosting device that can continually and steadily defrost and adopt
With the refrigerator of the device.
The present invention is to solve above-mentioned technical problem by the following technical programs：The present invention includes being connected by circulation by pipeline
Compressor, condenser, defrost heating tube, capillary, evaporator.
Preferably, further include drier, be connected between defrost heating tube and capillary.
Preferably, the global shape of the defrost heating tube is U-shaped.
Preferably, the defrost heating tube is copper pipe.
Preferably, further include one to be used to accelerate condenser cooling fan, be arranged in condenser side.
The present invention also provides a kind of refrigerator using the refrigerator doorframe defrosting system, the refrigerator includes babinet, door body, case
Body is connected through the hinge with door body, and the defrost heating tube is detachably arranged in inner side of door, compressor, condenser, capillary
Pipe, evaporator are arranged in babinet.
The present invention has the following advantages compared with prior art：The present invention has abandoned electrically heated mode in the prior art, profit
The pressure high temperature hot gas come out with compressor distributes a part of heat using condenser, and finally passing through defrost heating tube makes its liter
Temperature defrosts for refrigerator doorframe, can improve equipment effectiveness, the cold and hot exchange in refrigeration principle is rationally utilized；Also it carries significantly
The stability in use of high defrost heating device and service life.
Description of the drawings
Fig. 1 is a kind of structural schematic diagram of refrigerator doorframe defrosting system of the embodiment of the present invention.
Figure label:Compressor 1, condenser 2, defrost heating tube 3, capillary 4, evaporator 5, fan 6
Specific implementation mode
It elaborates below to the embodiment of the present invention, the present embodiment is carried out lower based on the technical solution of the present invention
Implement, gives detailed embodiment and specific operating process, but protection scope of the present invention is not limited to following implementation
Example.
As shown in Figure 1, a kind of refrigerator doorframe defrosting system of the present embodiment includes the compressor recycled successively by piping connection
1, condenser 2, defrost heating tube 3, capillary 4, evaporator 5.
The present embodiment further includes drier, is connected between defrost heating tube 3 and capillary 4.
The global shape of the defrost heating tube 3 is U-shaped, does not limit to this shape.
The defrost heating tube 3 is copper pipe.The major advantage of copper pipe：The advantages of copper pipe collection metal pipe material and non-metal pipe
.It is harder than plastic pipe, the high intensity with common metal, good toughness and ductility more flexible than common metal
Height has excellent antivibration, shock resistance and frost heaving resistant performance, and can bear extremely cold and very hot temperature,
The scope of application is big, and adaptive temperature acute variation, and performance will not be because being used for a long time the acute variation with temperature
And reduce, it not will produce aging phenomenon.
The present embodiment further includes one and is used to accelerate 2 cooling fan 6 of condenser, is arranged in 2 side of condenser.
The present invention also provides a kind of refrigerator using the refrigerator doorframe defrosting system, the refrigerator includes babinet, door body, case
Body is connected through the hinge with door body, and the defrost heating tube 3 is detachably arranged in inner side of door, specific dismountable installation
Mode can be taken：Groove is set in inner side of door face, defrosting heater is disposed therein, and inside is being connected to by plate
Face is embedded in inner side of door face, but does not limit to such mounting means.Using compressor 1 in the prior art, condenser 2, capillary
The set-up mode of pipe 4, evaporator 5, may be provided in babinet.
The SAPMAC method System Working Principle of refrigerator：
By the superheat refrigeration of 1 boil down to high temperature and pressure of compressor when the dry saturated gas of refrigerant of refrigerator passes through compressor 1
Agent steam is entered by the exhaust pipe of the expansion valve piston of compressor 1 in condenser 2, and the refrigerant vapour of high temperature and pressure exists
The liquid of high pressure low temperature is condensed into condenser 2, this liquid enters after filter of refrigerator by capillary 4 later,
Isenthalpic throttling becomes the refrigerant vapour of low-temp low-pressure in capillary 4, and the refrigerant of this low-temp low-pressure is in equipressure later
Boil a large amount of steam for absorbing extraneous heat and becoming saturation in evaporator 5, realizes the process of refrigerastion of refrigerator, finally freezes
Agent is sucked by compressor 1 carry out SAPMAC method again.
The course of work of the present invention：
When equipment making, a pre-buried defrost heating tube 3 along doorframe, and the extraction of defrost heating tube 3 in advance, access refrigeration
In the circulatory system.As shown in Figure 1, between defrost copper pipe access condenser 2 and drier, when work, the height that is come out from compressor 1
Super pressure-high temperature gas first passes around condenser 2 and distributes a part of heat, using defrost heating tube 3 so that 3 temperature of defrost heating tube
In 40 degrees centigrades, so that it may to defrost for refrigerator doorframe.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all essences in the present invention
All any modification, equivalent and improvement etc., should all be included in the protection scope of the present invention made by within refreshing and principle.
