Fig. 2 is the three-dimensional exploded view of the drain assembly 2 for refrigerator that provides of the embodiment of the present invention.
As shown in Figure 2, the drain assembly 2 for refrigerator that the embodiment of the present invention provides comprises drainpipe parts (parts of reference marks 21 and 23 indications) and inner conduit lid 22.
Particularly, drainpipe parts have the first opening 211 and the second opening 231 to the inside of refrigerator is in communication with the outside.Inner conduit lid 22 is arranged on the first opening 211 and sentences opening and closing the first opening 211.Inner conduit lid 22 has air pressure balance parts, and these air pressure balance parts are opened during over predetermined value at the pressure reduction of the air pressure of ambient pressure and refrigerator inside and with the inner chamber of conducting drainpipe parts and the inside of refrigerator and when the pressure reduction of the air pressure of ambient pressure and refrigerator inside is less than predetermined value, closed to disconnect the inner chamber of drainpipe parts and the conducting between refrigerator inside.
According to embodiments of the invention, the inner conduit of drain assembly 2 lid 23 has air pressure balance parts.When the pressure reduction of the air pressure of ambient pressure and refrigerator inside surpasses predetermined value, 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.
Drainpipe parts are tubular parts that the inside of refrigerator is in communication with the outside, and can play the double action of ventilation and draining.
Drainpipe parts can be configured to various structures, as long as can realize above-mentioned functions.For example, in the drain assembly 2 shown in Fig. 2, drainpipe parts consist of phase inner conduit 21 and outer water pipe 23.Particularly, the first end of inner conduit 21 (with reference to the left end of inner conduit in Fig. 2 21) opens wide to form the first opening 211, the second end of outer water pipe 22 (with reference to the right-hand member of outer water pipe in Fig. 2 22) opens wide to form the second opening 231, and second end (with reference to the right-hand member of inner conduit in Fig. 2 21) of the sheathed inner conduit 21 of the first end of outer water pipe 22 (with reference to the left end of outer water pipe in Fig. 2 22).
The first opening 211 that the modes such as inner conduit lid 22 is threaded connection, clamping are arranged on drainpipe parts is sentenced and is closed this first opening 211, thereby avoids refrigerator cold draining.And as mentioned above, inner conduit lid 22 has air pressure balance parts, thereby in the refrigerator course of work, reduce draught head between refrigerator inside and the external world or the air pressure inside and outside balance, make a door body for refrigerator be easy to open.
Air pressure balance parts can be configured to 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.As shown in Figures 2 to 4, air pressure balance parts comprise passage 221 and spool 222.Particularly, passage 221 is formed on inner conduit lid 22 with by the inner chamber of drainpipe parts and refrigerator internal communication.Spool 222 is located in passage 221, thereby open when the pressure reduction of the air pressure of ambient pressure and refrigerator inside surpasses predetermined value, closes to disconnect the inner chamber of drainpipe parts and the conducting between refrigerator inside with the inner chamber of conducting drainpipe parts and refrigerator inside and when the pressure reduction of the air pressure of ambient pressure and refrigerator inside is less than predetermined value.
As shown in Figure 3 and Figure 4, passage 221 preferably includes straight hole section 2211 and the reverse taper hole section 2212 being connected with these straight hole section 2211 upper ends, and spool 222 is arranged in reverse taper hole section 2212.Spool 222 has predefined weight, when the draught head of (being up and down between both sides of spool 222) between 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, make extraneous gas enter refrigerator inside via passage 221, reduce the inside and outside draught head of refrigerator.And being reduced to predetermined value when following when the air pressure between refrigerator inside and the external world, spool 222 will fall again to close passage 221, prevents refrigerator cold draining.
Spool 222 can form various shapes and structure by various materials.For example, in an embodiment of the present invention, spool 222 can form solid spheroid by plastics.Certainly, spool 222 is not limited to above-described embodiment, and it can manufacture various hollow or solid spheroids, cone, Rotary-table or laminated structure by materials such as plastics, glass, rubber or metals, as long as can realize its function.
In addition, in the present embodiment, as shown in Figure 3 and 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 from departing from from passage 221.On the other hand, handle 223 is convenient to grasp, and can provide convenience for using.
In addition, as shown in Figure 2, can also form at the first end of inner conduit 21 the first flange 214, and form second flange 224 suitable with described the first flange 214 on inner conduit lid 22.When inner conduit lid 22 is installed on to the first opening 211, the lower surface of the upper surface of the first flange 214 and the second flange 224 fits tightly, thereby improves the sealing property of refrigerator, prevents refrigerator cold draining.
In addition, as shown in Figure 2, the second end of outer water pipe 23 can also be provided with for opening and closing the cover piece 24 of the second opening 231, with when further preventing refrigerator cold draining, avoids extraneous foreign matter to enter in drainpipe parts these drainpipe parts are blocked.
Except the above-mentioned drain assembly for refrigerator, the embodiment of the present 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 air pressure balance parts.When the pressure reduction of the air pressure of ambient pressure and refrigerator inside surpasses predetermined value, air pressure balance parts will be opened with the inner chamber of drainpipe parts described in 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.
