The specific embodiment
Consider the problem that exists in the correlation technique, the invention provides a kind of drainpipe that is used for refrigerator.Describe embodiments of the invention below in detail, the example of described embodiment is shown in the drawings.Should be understood that below by the embodiment that is described with reference to the drawings be exemplary, only be used to explain the present invention, and can not be interpreted as limitation of the present invention.
Fig. 1 to Fig. 6 C shows the structural representation according to the embodiment of drainpipe of the present invention.Wherein Fig. 1 is the stereogram of drainpipe, and Fig. 2 A to Fig. 6 C shows the concrete structure of drainpipe respectively.
Referring to Fig. 1 to Fig. 4 B, drainpipe according to the present invention comprises main body pipe 1 and arm 3.Wherein, main body pipe 1 has first end 11, and arm 3 has the 3rd end 33, and another end of arm 3 is connected on the main body pipe 1.The first end 11 of main body pipe 1 is provided with the main body pipe pipe lid 2 towards the 1 outside unidirectional water flowing of main body pipe, and the 3rd end 33 of arm 3 is provided with the arm pipe lid 4 of unidirectional ventilation in arm 3.And, form angle α between the end face of main body pipe pipe lid 2 and the horizontal plane less than 90 °, so that when being installed in the refrigerator, main body pipe pipe lid 2 can not fitted with evaporating dish, the water that hinders in the main body pipe 1 flows out.
Referring to Fig. 1 to Fig. 4 B, arm 3 also comprises four end 34 relative with the 3rd end 33.The 4th end 34 is connected with the body of main body pipe 1 and is provided with away from first end 11.As shown in Figure 1, the 4th end 34 of arm 3 is connected on the body of main body pipe 1, and its body tilts towards the direction away from the first end 11 of main body pipe 1.Shown in Fig. 3 A and Fig. 3 B, the body of arm 3 is inclined upwardly from the body of main body pipe 1, and its 3rd end 33 be bent into from the body of arm 3 horizontal, thereby make the arm pipe lid 4 that is connected on the 3rd end 33 also be horizontally disposed with.
Shown in Fig. 4 A to Fig. 5 C, main body pipe pipe lid 2 comprises the 5th part 25, the 7th part 27 and first elastic component 28.Wherein, shown in Fig. 4 B, the 5th part 25 is cylindric body, and its cylindric part is set on the first end 11 of main body pipe 1.The 7th part 27 is positioned at the below of the 5th part 25, and and the 5th part 25 between be provided with spacing L.First elastic component 28 is used to connect the 5th part 25 and the 7th part 27.The part of first elastic component 28 is connected with the lower surface of the 7th part 27, and and horizontal plane between form angle [alpha] less than 90 °.
In the present embodiment, shown in Fig. 4 B, first elastic component 28 comprises the first arm and second arm that is connected with the first arm.Wherein, the first arm is connected with the 7th part 27 and is positioned on the lower surface of the 7th part 27, and forms the angle [alpha] less than 90 ° between the first arm and the horizontal plane, and second arm is connected with the 5th part 25 with the 7th part 27 simultaneously.
According to the present invention, when in the drainpipe water being arranged, water covers 2 at effect current downflow to the main body pipe pipe of gravity, because first elastic component 28 has elasticity, the 7th part 27 rotates under the pressure of water, and the water in the drainpipe is flowed out.After discharge water, first 27 reposition under the effect of first elastic component 28 covers on the main body pipe pipe lid 2 again, in the isolated refrigerator with the heat exchange in the external world.
Shown in Fig. 2 C, the 3rd end 33 of arm 3 comprises the opening that is communicated with the 4th end 34.Wherein, this opening flatly is provided with, and towards the first end 11 of main body pipe 1.As Fig. 3 B and Fig. 6 A to Fig. 6 C, arm pipe lid 4 comprises the 6th part 46, the 8th part 48 and second elastic component 47.Wherein, the 6th part 46 is positioned at the below of the 8th part 48, and the part of the 6th part 46 is inserted in the opening of the 3rd end 33 of arm 3 with the 8th part 48.Be provided with the second gap M between the 8th part 48 and the 6th part 46, and be connected with the 6th part 46 by second elastic component 47.Second elastic component 47 connects the 6th part 46 and the 8th part 48 simultaneously, and the part of second elastic component 47 is arranged on the upper surface of the 6th part 46.
When opening refrigerator doors, because refrigerator is interior and the pressure differential of external environment, second elastic component drives the 8th part 48 towards arm 2 inner rotation, and air enters in the refrigerator by arm pipe lid 2, has solved because of opening the door of causing of return-air smoothly to require great effort and the buzz noise problem.When turning a refrigerator off, because second elastic component 47 has elasticity, it drives the 8th part 48 and returns back to original position, prevents that outside air from entering in the refrigerator, thereby has realized the function of unidirectional ventilation in refrigerator, prevents heat exchange.
In the present embodiment, main body pipe 1 is cylindric hollow tube, arm 3 be trapezium structure along the cross section of making perpendicular to its center line.The body bore at close 33 places, the 3rd end of arm 3 is greater than the body bore at 34 places, the 4th end, and the body bore near place, the 3rd end of arm 2 is twices of main body pipe body bore.
According to a further aspect in the invention, also provide a kind of refrigerator, be provided with according to drainpipe of the present invention in this refrigerator.
Utilization is according to drainpipe of the present invention, and by the main body pipe pipe lid 2 in end setting unidirectional water flowing outside main body pipe 1 of main body pipe 1, during draining, main body pipe pipe lid 2 is opened, and during defrost, main body pipe pipe lid 2 is closed, and effectively prevents heat exchange.And main body pipe pipe lid 2 is a ramp structure, can prevent that the applying of drainpipe and evaporating dish from hindering effective draining.
Simultaneously, increase arm 3 on the drainpipe main body pipe 1, and at the arm 3 terminal arm pipe lids 4 that unidirectional ventilation in drainpipe is set, make that the resistance when opening refrigerator doors is littler, and closing refrigerator arm pipe lid 4 behind the door returns to closure state again, isolated extraneous hot gas effectively prevents heat exchange, and requires great effort because of opening the door of causing of return-air smoothly when avoiding opening the door and problems such as buzz noise.
And owing to effectively prevent heat exchange according to drainpipe of the present invention, the energy loss of also having avoided heat exchange to produce plays energy-conserving action.
Although illustrated and described embodiments of the invention, for the ordinary skill in the art, be appreciated that without departing from the principles and spirit of the present invention and can carry out multiple variation, modification, replacement and modification that scope of the present invention is by claims and be equal to and limit to these embodiment.
