Described notch portion 36 be subjected to refluxing the defrost water that prevents that part 37 bottoms are collected the gravity effect and open, and after defrost water prevents part 37 by the notch portion 36 discharge backflows of opening, described notch portion 36 is closed, thereby extraneous air can not flow into the inside of refluxing and preventing part 37 by notch portion 36.
Change the operation of the ON/OFF part 40 of caused draining valve 30 to Fig. 7 introduction by the pressure in the storeroom below with reference to Fig. 4, wherein above-mentioned pressure changes owing to cause after the refrigerator door open-close.
Shown in Figure 4 and 5, the air flow ports 33 of described ON/OFF part 40 valve body 35.At this moment, because the flange portion 43 of ON/OFF part 40 engages with the support section 34 of valve body 35, described ON/OFF part 40 maintains the closed position, so that the air flow ports 33 of valve body 35, and the through hole 42 of ON/OFF part 40 prevents that with drainpipe 23, defrost water flow orifice 32 and backflow part 37 is connected.
In view of the above, because the defrost water that is produced for evaporimeter 9 defrostings at first drops onto draining receiving element 22, flow downward along drainpipe 23 through floss hole 21 subsequently.The defrost water that flows along drainpipe 23 is discharged into water-collecting tray 6 through draining valve 30.At this moment, the defrost water that flows into draining valve 30 from drainpipe 23 is passed through the defrost water flow orifice 32 of valve body 35 and the through hole 42 of ON/OFF part 40, and drops onto the bottom of refluxing and preventing part 37.At this moment, open under the gravity effect of defrost water because backflow prevents the notch portion 36 of part 37, defrost water is discharged into water-collecting tray 6 by the notch portion of opening 36.The notch portion 36 that is subjected to the gravity of defrost water and opens is closed after defrost water is discharged again, and thus, air can not flow in the draining valve member 30 by notch portion 36.
When the user opened refrigerator doors 7a and 7b and closes them once more, extraneous air flowed into refrigerating chamber 3a and refrigerating chamber 3b.At this moment, the air in refrigerating chamber 3a and the refrigerating chamber 3b shrinks, and causes that thus the pressure of storeroom 3a and 3b changes.Because described pressure changes, the ON/OFF part 40 of draining valve 30 moves up, shown in Fig. 6 and 7.Moving up of ON/OFF part 40 by closing air flow ports 33 before, the air flow ports 33 of valve body 35 is opened, and extraneous air flows into valve bodies 35 by described air flow ports 33.The air that flows into valve body 35 flows into drainpipe 23 through the through hole 42 and the defrost water flow orifice 32 of switch member 40.The air that flows into drainpipe 23 continues upwards to flow and flow into refrigerating chamber 3a and refrigerating chamber 3b, and the pressure of having eliminated thus in storeroom 3a and the 3b changes.Like this, just can enough very little strength easily open refrigerator doors 7a and 7b.When the pressure in storeroom 3a and the 3b changes because after air inflow refrigerating chamber 3a and refrigerating chamber 3b be eliminated out, the ON/OFF part 40 of draining valve 30 moved down and return to the closed position under the self gravitation effect, as shown in Figure 4 and Figure 5.
Described ON/OFF part 40 with through hole 42 can be arranged in the valve body 35 of draining valve 30 with raising, is used to pass air into refrigerating chamber 3a and refrigerating chamber 3b, also is used to block air and flows into refrigerating chamber 3a and refrigerating chamber 3b, and be used to make defrost water to pass through.In view of the above, draining valve 30 is carried out two functions by simple structure: discharge defrost water and pass air into refrigerating chamber and refrigerating chamber 3a and 3b.
In addition, because draining valve 30 outward appearances are very thin, even therefore in narrow space, also can easily install.And because the internal diameter of through hole 42 and drainpipe 23 is roughly the same, so extraneous air can promptly flow into drainpipe 23.
As indicated above, according to the present invention, when the internal pressure of storeroom and external pressure balance, when can preventing that extraneous air from flowing into storeroom, can also be by draining valve simple in structure with defrosting draining to outside.Even the pressure that causes storeroom owing to open the door and close the door changes, extraneous air also can flow in the storeroom, thereby helps the unlatching of refrigerator doors.
Although this paper diagram has also been introduced several embodiments of the present invention; but those skilled in the art answer described recognizing; can make various changes to embodiments of the invention without departing from the principles and spirit of the present invention; wherein, protection scope of the present invention is limited by claim and equivalent thereof.
