Specific embodiment
It is practical new below in conjunction with this to keep the objectives, technical solutions, and advantages of the embodiments of the present invention clearer
Attached drawing in type embodiment, the technical scheme in the utility model embodiment is clearly and completely described, it is clear that is retouched
The embodiment stated is the utility model a part of the embodiment, instead of all the embodiments.Based on the implementation in the utility model
Example, every other embodiment obtained by those of ordinary skill in the art without making creative efforts belong to
The range of the utility model protection.
The utility model discloses a kind of wind inlet of fan defrosting device of wind cooling refrigerator, referring to Figures 1 and 2, including fan
200,200 face of fan has air inlet 300.Heating tube 100, the import of heating tube 100 and refrigeration for refrigerator are equipped at air inlet 300
The outlet of compressor 610 in circuit 600, the outlet of heating tube 100 and the evaporator 640 in refrigerator refrigeration loop 600
Inlet communication, alternatively, the inlet communication of the outlet of heating tube 100 and compressor 610.
Specifically, refrigerating circuit 600 include link together compressor 610, condenser 620, throttling set 630 and
Evaporator 640, referring to Fig. 3.Refrigerating circuit 600 further includes heating tube 100, the import of heating tube 100 and the outlet of compressor 610
The inlet communication of connection, the outlet of heating tube 100 and evaporator 640, alternatively, the outlet of heating tube 100 and compressor 610 into
Mouth connection.When needing to 300 defrost of wind inlet of fan, heating tube branch is opened, the high temperature and high pressure steam exported from compressor 610
Enter in heating tube 100, heating tube 100 is set at air inlet 300, the heat of high temperature and high pressure steam by heating tube 100 to
Outer heat dissipation is to carry out heating defrost to wind inlet of fan 300.It, being capable of maximum limit since heating tube 100 is close to air inlet 300
Degree ground transfers heat to air inlet 300, raising defrosting effect, avoid at air inlet 300 frost accumulated more and more and by fan 200
It stumbles or freezes, influence the service performance of refrigerator.Meanwhile the heat for making full use of compressor 610 to be discharged, it does not need additionally to increase
Add energy resource supply, advantageously reduces energy consumption, and safe and reliable.
When the outlet of heating tube 100 is set as the inlet communication with evaporator 640, high temperature and high pressure steam passes through heating tube
100 are flowed into evaporator 640, can also equably heat to evaporator 640, play to the quick defrost of evaporator 640
Effect.The outlet of heating tube 100 and the inlet communication of evaporator 640 are the preferred embodiment of the present embodiment.
The import of heating tube 100 by the outlet of solenoid valve 650 and compressor 610, when need to air inlet 300 into
When row defrost, solenoid valve 650 is opened, and heating tube branch is connected to.
The material of heating tube 100 is preferably the high copper or aluminium of heating conduction, improves radiating efficiency.
From figure 2 it can be seen that air inlet 300 has certain width along its longitudinal direction, if heating tube 100 is set to
The inside of air inlet 300, will affect the air inlet effect of air inlet 300, and also be unfavorable for installing, so heating tube 100 is preferred
For set on the outside of air inlet 300.
The wind inlet of fan defrosting device is applied to wind cooling refrigerator.Specifically, the lower section of evaporator 640 is equipped with water receiving
Disk, air inlet are formed on drip tray 400.Air inlet 300 and drip tray 400 are become one structure, advantageously reduced into
This.Also, air inlet 100 is obliquely installed obliquely relative to drip tray 400, to avoid the ponding in drip tray 400 from air inlet
It is outer at mouthful to drop down.Certainly, in other embodiments, air inlet 300 can be formed on independent air intake cover.
In the process of running, showing for frosting can all occur to wind cooling refrigerator in drip tray 400, drainpipe 500 and evaporator 640
As, the present embodiment is while realizing 300 defrost of wind inlet of fan, also to drip tray 400, drainpipe 500 and evaporator 640 into
Row heating defrost.
Specifically, heating tube 100 is formed with the first heating pipeline section 110, second heating pipeline section 120 along refrigerant flow direction
And third heats pipeline section 130.Circumferentially structure is set on the outside of air inlet 300 for first heating pipeline section 110, for entering the wind to fan
Mouth 300 carries out heating defrost.Second heating pipeline section 120 is layed in the outside of drip tray 400 in coil-like structure, for water receiving
Disk 400 carries out heating defrost.Third heating pipeline section is wound in the outside of drainpipe 500, for carrying out heating to drainpipe 500
Frost.
When defrost, solenoid valve 650 is opened, and heating tube branch is opened, and the high temperature and high pressure steam exported from compressor 610 enters
Into heating tube 100, pipeline section 120, evaporator are heated followed by the first heating pipeline section 110, third heating pipeline section 130, second
640, it is finally back in compressor 610.The heat of high temperature and high pressure steam is radiated outward by heating tube 100, thus realization pair
The heating defrost of air inlet 300, drainpipe 500, drip tray 400 and evaporator 640.
The outer surface of drip tray 400 is equipped with thermal insulative board (not shown), and heating tube 100 is pressed against thermal insulative board and drip tray
Between 400, thermal insulative board makes heat all be transferred to air inlet it is possible to prevente effectively from the heat that distributes of heating tube 100 is exchanged with the external world
300 and drip tray 400 on, improve defrosting effect.Specifically, the first heating pipeline section 110 and the second heating pipeline section 120 are by thermal insulative board
It is pressed against between thermal insulative board and drip tray 400.
The outside of thermal insulative board, drip tray 400 and air inlet 300 is respectively formed with to be added with the first heating pipeline section 110 and second
120 matched groove structure (not shown) of hot pipe section, when assembling heating tube 100, groove plays the role of Primary Location, is convenient for
Installation.Meanwhile groove structure is but also 300 outside of the first heating pipeline section 110 and air inlet, the second heating pipeline section 120 and water receiving
Connection between disk 400 is more solid and reliable.
The geometric center that fan 200, first heats pipeline section 110 and air inlet 300 is located along the same line, convenient for assembly and
Air inlet.
Finally, it should be noted that above embodiments are only to illustrate the technical solution of the utility model, rather than its limitations；
Although the utility model is described in detail with reference to the foregoing embodiments, those skilled in the art should understand that:
It is still possible to modify the technical solutions described in the foregoing embodiments, or part of technical characteristic is carried out etc.
With replacement；And these are modified or replaceed, various embodiments of the utility model technology that it does not separate the essence of the corresponding technical solution
