Fig. 2 is the three-dimensional exploded view of the drain assembly that is used for refrigerator 2 that provides of the embodiment of the invention.
As shown in Figure 2, the drain assembly that is used for refrigerator 2 that the embodiment of the invention provides comprises drainpipe parts (parts of reference marks 21 and 23 indications) and inner conduit lid 22.
Particularly, the drainpipe parts have first opening 211 and second opening 231 so that the inside of refrigerator is in communication with the outside.Inner conduit lid 22 is installed in first opening 211 and sentences opening and closing first opening 211.Inner conduit lid 22 has the air pressure balance parts, and these air pressure balance parts are opened when the pressure reduction of the inner air pressure of ambient pressure and refrigerator surpasses predetermined value with the inside of the inner chamber of conducting drainpipe parts and refrigerator and at the pressure reduction of the air pressure of ambient pressure and refrigerator inside and closed with the inner chamber of disconnection drainpipe parts and the conducting between the refrigerator inside during less than predetermined value.
According to embodiments of the invention, the inner conduit of drain assembly 2 lid 23 has the air pressure balance parts.When the pressure reduction of the inner air pressure of ambient pressure and refrigerator surpasses predetermined value; The air pressure balance parts will be opened with the inner chamber of conducting drainpipe parts and the inside of refrigerator; Thereby allow extraneous gas to enter into refrigerator inside along the inner chamber of drainpipe parts; Reduce the inside and outside draught head of refrigerator, so that the door body of refrigerator is easy to open.
The drainpipe parts are tubular parts that the inside with refrigerator is in communication with the outside, and can play the double action of ventilation and draining.
The drainpipe parts can constitute various structures, as long as can realize above-mentioned functions.For example, in drain assembly shown in Figure 22, the drainpipe parts are made up of phase inner conduit 21 and outer water pipe 23.Particularly; First end of inner conduit 21 (with reference to the left end of inner conduit among Fig. 2 21) opens wide to constitute first opening 211; Second end of outer water pipe 22 (with reference to the right-hand member of outer water pipe among Fig. 2 22) opens wide constituting second opening 231, and second end (with reference to the right-hand member of inner conduit among Fig. 2 21) of the sheathed inner conduit 21 of first end of outer water pipe 22 (with reference to the left end of outer water pipe among Fig. 2 22).
The air pressure balance parts can constitute various structures, as long as can realize above-mentioned functions.For example, Fig. 2 to Fig. 4 shows a kind of typical structure of air pressure balance parts.To shown in Figure 4, the air pressure balance parts comprise passage 221 and spool 222 like Fig. 2.Particularly, passage 221 is formed on the inner conduit lid 22 with inner chamber and refrigerator internal communication with the drainpipe parts.Spool 222 is located in the passage 221, thereby it is inner and close with the inner chamber of disconnection drainpipe parts and the conducting between the refrigerator inside during less than predetermined value at the pressure reduction of ambient pressure and the air pressure of refrigerator inside with refrigerator when the pressure reduction of the inner air pressure of ambient pressure and refrigerator surpasses predetermined value, to open inner chamber with conducting drainpipe parts.
Like Fig. 3 and shown in Figure 4, passage 221 preferably includes straight hole section 2211 and the reverse taper hole section 2212 that links to each other with these straight hole section 2211 upper ends, and spool 222 is arranged in the reverse taper hole section 2212.Spool 222 has predefined weight; When the draught head of (being up and down between the both sides of spool 222) between the refrigerator inside and the external world is enough to overcome the weight of spool 222; Spool 222 will be by jack-up to open passage 221; It is inner to make that extraneous gas gets into refrigerator via passage 221, reduces the inside and outside draught head of refrigerator.And being reduced to predetermined value when following when the air pressure between the refrigerator inside and the external world, spool 222 will fall to close passage 221 again, prevents the refrigerator cold draining.
Spool 222 can form different shape and structure through various materials.For example, in an embodiment of the present invention, spool 222 can form solid spheroid through plastics.Certainly, spool 222 is not limited to the foregoing description, and it can become various hollow or solid spheroids, cone, Rotary-table or laminated structure through made such as plastics, glass, rubber or metals, as long as can realize its function.
In addition, in the present embodiment, like Fig. 3 and shown in Figure 4, the top of inner conduit lid 22 can also be provided with the handle 223 of arc, and spool 222 is positioned at the below of this handle 223.On the one hand, handle 223 can play restriction to spool 222, thereby prevents that spool 222 breaks away from from passage 221.On the other hand, handle 223 is convenient to grasping, can provide convenience for use.
In addition, as shown in Figure 2, can also form first flange 214 at first end of inner conduit 21, and on inner conduit lid 22, form and the second suitable flange 224 of said first flange 214.When inner conduit lid 22 was installed on first opening 211, the lower surface of the upper surface of first flange 214 and second flange 224 fitted tightly, thereby improves the sealing property of refrigerator, prevents the refrigerator cold draining.
In addition, as shown in Figure 2, second end of outer water pipe 23 can also be provided with the cover piece 24 that is used to open and close second opening 231, with when further preventing the refrigerator cold draining, avoids extraneous foreign matter to get in the drainpipe parts these drainpipe parts are blocked.
Except that the above-mentioned drain assembly that is used for refrigerator, the embodiment of the invention also provides a kind of refrigerator that above-mentioned drain assembly 2 is installed.
According to the abovementioned embodiments of the present invention, the inner conduit of the drain assembly 2 of refrigerator lid 22 has the air pressure balance parts.When the pressure reduction of the inner air pressure of ambient pressure and refrigerator surpasses predetermined value; The air pressure balance parts will be opened with the inner chamber of the said drainpipe parts of conducting and the inside of refrigerator; Thereby allow extraneous gas to enter into refrigerator inside along the inner chamber of drainpipe parts; Reduce the inside and outside draught head of refrigerator, so that the door body of refrigerator is easy to open.
In the description of this specification, the description of reference term " embodiment ", " some embodiment ", " example ", " concrete example " or " some examples " etc. means the concrete characteristic, structure, material or the characteristics that combine this embodiment or example to describe and is contained at least one embodiment of the present invention or the example.In this manual, the schematic statement to above-mentioned term not necessarily refers to identical embodiment or example.And concrete characteristic, structure, material or the characteristics of description can combine with suitable manner in any one or more embodiment or example.
Although illustrated and described embodiments of the invention above; It is understandable that; The foregoing description is exemplary; Can not be interpreted as limitation of the present invention, those of ordinary skill in the art can change the foregoing description under the situation that does not break away from principle of the present invention and aim within the scope of the invention, modification, replacement and modification.
