Detailed description of the invention
In view of problem present in correlation technique, the present invention provides a kind of drainpipe for refrigerator.
Embodiments of the invention are described below in detail, and the example of described embodiment is shown in the drawings.Should be understood that
The embodiment describing below with reference to accompanying drawing is exemplary, is only used for explaining the present invention, and can not
It is construed to limitation of the present invention.
Fig. 1 to Fig. 6 C shows the structural representation of the embodiment of the drainpipe according to the present invention.Wherein
Fig. 1 is the stereogram of drainpipe, and Fig. 2 A to Fig. 6 C respectively illustrates the concrete structure of drainpipe.
See Fig. 1 to Fig. 4 B, include main body tube 1 and arm 3 according to the drainpipe of the present invention.Wherein,
Main body tube 1 has first end 11, and arm 3 has the 3rd end 33, and another of arm 3
End is connected on main body tube 1.It is provided with outside main body tube 1 on the first end 11 of main body tube 1
The main body tube lid 2 of the unidirectional water flowing in portion, the 3rd end 33 of arm 3 is provided with in arm 3
The arm lid 4 of one-way ventilating.Further, formed between the end face of main body tube lid 2 and horizontal plane little
In the angle α of 90 °, in order to when being arranged in refrigerator, main body tube lid 2 will not be fitted with evaporating dish,
The water in main body tube 1 is hindered to flow out.
Seeing Fig. 1 to Fig. 4 B, arm 3 also includes fourth end 34 relative with the 3rd end 33.
4th end 34 is connected with the body of main body tube 1 and arranges away from first end 11.Such as Fig. 1 institute
Showing, the 4th end 34 of arm 3 is connected on the body of main body tube 1, and its body is directed away from
The direction of the first end 11 of main body tube 1 tilts.As shown in Figure 3 A and Figure 3 B, the pipe of arm 3
Body is inclined upwardly from the body of main body tube 1, and its 3rd end 33 is curved from the body of arm 3
It is converted into horizontal, so that the arm lid 4 being connected on the 3rd end 33 is also horizontally disposed with.
As shown in Fig. 4 A to Fig. 5 C, main body tube lid 2 includes Part V the 25th, Part VII 27
And first elastic component 28.Wherein, as shown in Figure 4 B, Part V 25 is cylindric body, its
Cylindrical portion is set on the first end 11 of main body tube 1.Part VII 27 is positioned at Part V
The lower section of 25, and and Part V 25 between be provided with spacing L.First elastic component 28 is for even
Connect Part V 25 and Part VII 27.A part for first elastic component 28 and Part VII 27
Lower surface connects, and and horizontal plane between formed less than the angle [alpha] of 90 °.
In the present embodiment, as shown in Figure 4 B, the first elastic component 28 include the first arm and with the first arm
The second arm connecting.Wherein, the first arm is connected with Part VII 27 and is positioned at Part VII 27
On lower surface, and forming the angle [alpha] less than 90 ° between the first arm and horizontal plane, the second arm is simultaneously
It is connected with Part VII 27 and Part V 25.
According to the present invention, when there being water in drainpipe, water flows to main body tube pipe under gravity
Lid 2, owing to the first elastic component 28 has elasticity, Part VII 27 rotates down under the pressure of water,
The water in drainpipe is made to flow out.After discharging water, Part I 27 is in the effect of the first elastic component 28
Lower return in situ, covers in main body tube lid 2 again, with extraneous heat exchange in isolation refrigerator.
As shown in Figure 2 C, the 3rd end 33 of arm 3 includes the opening connecting with the 4th end 34.
Wherein, this open horizontal ground is arranged, and towards the first end 11 of main body tube 1.Such as Fig. 3 B and
Fig. 6 A to Fig. 6 C, arm lid 4 includes that Part VI the 46th, Part VIII 48 and second is elastic
Part 47.Wherein, Part VI 46 is positioned at the lower section of Part VIII 48, and Part VI 46
In the opening of the 3rd end 33 that a part is inserted in arm 3 together with Part VIII 48.8th
It point is provided with the second gap M between 48 and Part VI 46, and pass through the second elastic component 47 and the
Six parts 46 connect.Second elastic component 47 is simultaneously connected with Part VI 46 and Part VIII 48, and
And second the part of elastic component 47 be arranged on the upper surface of Part VI 46.
When opening refrigerator doors, due to the pressure differential with external environment in refrigerator, the second elastic component drives the
Eight parts 48 enter in refrigerator by arm lid 2 towards arm 2 inner rotation, air, solve
Because of cannot return-air causes smoothly enabling arduously and buzz noise problem.When turning a refrigerator off, due to
Second elastic component 47 has elasticity, and it drives Part VIII 48 to return back in situ, prevent outside air
Enter in refrigerator, it is achieved thereby that towards the function of one-way ventilating in refrigerator, prevent heat exchange.
In the present embodiment, main body tube 1 is cylindric hollow tube, arm 3 along being perpendicular to it
The cross section that center line is made is trapezium structure.The body bore at the 3rd end 33 of arm 3 is big
Body bore at the 4th end 34, and arm 2 near the body bore of the 3rd end is
The twice of main body tube body bore.
According to a further aspect in the invention, additionally provide a kind of refrigerator, this refrigerator is provided with according to this
The described drainpipe of invention.
Utilize the drainpipe according to the present invention, arranged towards main body tube 1 by the end at main body tube 1
The main body tube lid 2 of outer unidirectional water flowing, during draining, main body tube lid 2 is opened, during defrost, main body
Pipe lid 2 is closed, and effectively prevents heat exchange.And main body tube lid 2 is ramp structure, Neng Goufang
Only drainpipe and evaporating dish laminating hinders effective draining.
Meanwhile, drainpipe main body tube 1 increases arm 3, and arrange towards draining at arm 3 end
The arm lid 4 of one-way ventilating in pipe so that resistance when opening refrigerator doors is less, and closes ice
After chamber door, arm lid 4 returns to again closure state, the extraneous hot gas of isolation, effectively prevents heat exchange,
And when avoiding opening the door because of cannot return-air causes smoothly enabling arduously and the problem such as buzz noise.
Further, owing to effectively preventing heat exchange according to the drainpipe of the present invention, it is thus also avoided that heat exchange is produced
Raw energy loss, plays energy-conserving action.
Although an embodiment of the present invention has been shown and described, for those of ordinary skill in the art
For, it is possible to understand that without departing from the principles and spirit of the present invention can be to these embodiments
Carry out multiple change, modification, replacement and modification, the scope of the present invention by claims and etc.
With restriction.
