The embodiment of the utility model provides a rear side of storeroom is provided with wind channel 110, as shown in fig. 2, the bottom in wind channel 110 is provided with and is used for the drainage the outside drain pipe 300 of box 100, as shown in fig. 3, drain pipe 300 stretches out be provided with the protruding edge 310 of annular on the outside one end inner wall of box 100, the protruding edge 310 middle part of annular forms wash port 320, drain pipe 300 is at the drainage in-process, as shown in fig. 5, the water that flows in the drain pipe can be plugged up wash port 320, reaches sealed effect, works as after the water in drain pipe 300 is discharged, as shown in fig. 6, remaining water droplet passes through the tension of water in drain pipe 320 can suspend in wash port 320 department, plugs up wash port 320 reaches sealed effect.

The embodiment of the utility model provides a refrigerator, because be provided with the protruding edge 310 of round annular on the inner wall of the export of drain pipe 300, the protruding edge 310 middle part of annular forms the wash port 320 that is used for the drainage, thereby make the diameter of wash port 320 be less than the internal diameter of drain pipe 300, so drain pipe 300 is at the drainage in-process, the wash port 320 can be stopped up to the hydroenergy that flows, outside air can not pass through the drain pipe, get into the box 100 inside, therefore, can reach sealed effect, after the water in the drain pipe is discharged, when the interior surplus drain pipe 320 of drain pipe 300 flows into wash port 320, because there is the appeal between the different materials, make the water droplet can adhere to on the inner wall of wash port 320, and water self has tension, therefore, the water droplet can suspend in wash port 320 department, stop up 320, reach sealed effect, thereby realize the inside and the outside of isolated box 100, the external hot air is prevented from entering the inside of the cabinet 100 through the drain pipe 300 to affect the storage temperature inside the cabinet 100, and no additional parts are required, resulting in low overall cost.

Because the tension of water is limited, will make the water droplet can suspend downtheholely, then need set up suitable aperture to make the water droplet can suspend in wash port 320 department through the tension of self, if the aperture is too big, the tension of water droplet can not make the water droplet suspend downthehole, if the aperture is too little, when the water of gathering up in drain pipe 300 is more, again cause the drainage to be smooth and easy, consequently, the embodiment of the utility model provides a wash port 320 is through experimental verification repeatedly, when the diameter of wash port 320 is 8-10mm, the water droplet can realize suspending in wash port 320 department to can guarantee that the drainage is smooth and easy, can not block up drain pipe 300.

Preferably, the diameter of the drain hole 320 is 8 mm. Through the experiment verification that relapses, when the aperture of wash port 320 sets up to 8mm, the water droplet can be stably suspended in wash port 320 department, can not drip to realize forming seal structure through the water droplet, isolated box 100 is inside and outside, prevents that the outside hot-air of box 100 from passing through drain pipe 300 and getting into inside box 100, influences the storage temperature of the inside storeroom of box 100.

In the case that the water in the drain pipe 300 is much and flows, most of the water is drained due to the gravity of the water, and no water drops are suspended at the drain hole 320, when most of the water in the drain pipe 300 is drained and little of the water is accumulated in the drain pipe 300, because the surface of the annular flange 310 facing the inside of the drain pipe 300 is a plane, local water drops are formed on the plane, and the water drops can stay on the plane without external force, and cannot flow to the drain hole 320, so that no water drops are suspended at the drain hole 320, as shown in fig. 3 and 4, a first flow guide surface 330 is provided on the surface of the annular flange 310 facing the inside of the drain pipe 300, and the first flow guide surface 330 extends from the edge of the drain hole 320 to the periphery and inclines in a direction away from the drain hole 320, the water in the drain pipe 300 can flow into the drain hole 320 along the first drainage surface. When the accumulated water in the drain pipe 300 is less, the remaining water drops flow into the drain hole 320 along the first drainage surface 330 through the first drainage surface 330, and when the gravity of the remaining water drops is smaller than the tension of the water drops and the adsorption force between the gravity of the remaining water drops and the inner wall of the drain hole 320, the water drops can be suspended at the drain hole 320 to block the drain hole 320, so that a sealing effect is formed.

In order to enable water to flow into the drain pipe 300 quickly, the inner diameter of the drain pipe 300 provided by the embodiment of the present invention is gradually reduced from the end close to the inside of the box 100 to the end far away from the inside of the box 100. Set up the diameter of drain pipe 300 entrance great, when ponding is more, ponding also can flow in the drain pipe 300 fast, prevent to form ponding in box 100 inside, and further freeze, the problem that leads to drain pipe 300 to block up takes place, and the diameter setting with the export of drain pipe 300 is less than the entry diameter, make ponding get into behind the drain pipe 300, pressure increase, the velocity of flow increases, thereby make the fast discharge of hydroenergy in the drain pipe 300, it is too much to avoid the water accumulation in the drain pipe 300, lead to forming ponding in box 100 inside, and then lead to freezing, cause the drainage to block up, influence refrigerator normal operating.

As shown in fig. 2 and fig. 3, the drain pipe 300 provided by the embodiment of the present invention is located on the outer wall of one end inside the box 100, and a ring-shaped protrusion 340 is provided on the outer wall of the end inside the box 100, and the ring-shaped protrusion 340 is used for being clamped at the bottom end of the air duct 110.

After the defrosting water that produces in wind channel 110 drips downwards, all drip on the bottom surface of wind channel 110 below, if this bottom surface sets up to a plane, then can cause the water droplet to stop in the position of dripping, only when ponding is too much, ponding just can be discharged through drain pipe 300, and the water droplet that stops on the bottom surface, if not discharge for a long time, because the temperature in wind channel 110 is lower, can lead to the water droplet to freeze locally on the plane of wind channel 110 below, form the large tracts of land and freeze as of a long time, the condition that blocks up drain pipe 300 even takes place.

Therefore, as shown in fig. 2, a second flow guiding surface 120 is disposed at a bottom end of the air duct 110, the second flow guiding surface 120 gradually extends from an inlet of the water discharging pipe 300 to the periphery and inclines towards a direction away from the water discharging pipe 300, and water dropping from the air duct 110 can flow into the water discharging pipe 300 along the second flow guiding surface 120. The plane at the bottom end of the air duct 110 is set to be an inclined plane structure, so that the dropped water drops are guided to the inlet of the drain pipe 300 through the second flow guide surface 120, the dropped water drops smoothly enter the drain pipe 300, and accumulated water which cannot be smoothly discharged is prevented from being at the bottom end of the air duct 110.

Further, as shown in fig. 2, a water receiving tray for collecting water discharged from the water discharge pipe 300 is provided at the bottom of the box body 100, and the water receiving tray 400 is detachably connected to the box body 100. Collect exhaust defrosting water through water collector 400 to prevent that the exhaust rivers are subaerial, and water collector 400 below is provided with compressor 500, and when normal work, compressor 500's temperature is higher, consequently, defrosting water in the water collector 400 can be evaporated, thereby avoids repeatedly going to clear up the ponding in the water collector 400.

It should be pointed out, to some special cases, for example, refrigerator door body 200 is sealed not tight, leads to changing the frost volume increase, and it is more to change the frost water, and at this moment, need in time clear up the ponding in the water collector 400, prevents that ponding from overflowing too much, flows to subaerially, consequently, the utility model discloses be connected through the mode of dismantling the connection between preferred water collector 400 of embodiment and the box 100, when needs clearance water collector 400, can be convenient take out water collector 400, promote user experience.

Preferably, the detachable connection can be connected through a buckle, a bolt, and other connection fixing methods, that is, the water pan 400 is fixed on one surface of the foaming layer facing the compressor 500 through the buckle or the bolt, and a fixing bracket is also arranged at the bottom of the box body 100 and used for supporting the water pan 400, so that the water pan 400 is just opposite to the outlet of the drain pipe 300.
