Description
- The present utility model relates to the field of household appliances, and particularly to a refrigerator.
- The prior art discloses that a refrigerating chamber and a freezing chamber of a refrigerator are provided with drain pipes, used to discharge condensate water or defrosting water in compartments. As the drain pipes are directly in communication with the outside or a water pan in a machine room, in order to prevent cool air in the freezing chamber from flowing out along the drain pipe in the freezing chamber or outside hot air from entering into the freezing chamber, a coiled pipe structure is used at the tail of the drain pipe of the freezing chamber, some condensate water discharged out of the freezing chamber remains in a coiled pipe section at the tail of the drain pipe, to prevent the freezing chamber from communicating with the outside.
- Although the aforementioned structure has effectively avoided reduction of refrigerating efficiency caused by that the drain pipe of the freezing chamber directly communicates with the outside, a new problem may arise. A user opens the door of the freezing chamber, some hot air may enter into the freezing chamber, after the door is closed for a period of time, the hot air is cooled, air pressure in the freezing chamber is reduced, water in the drain pipe of the freezing chamber will flow towards the direction of the freezing chamber under the action of outside atmospheric pressure, and although the possibility that the water will flow back to the freezing chamber is quite low, the flowing water will make a sound easy to make the user perceive, the user's product experience is affected.
- JPH 11 132640 A discloses a refrigerator in a top freezer configuration having one evaporator supplying freezer and cooler chamber.
- JPS 64 48569 U discloses a refrigerator comprising two storage chambers, each having an associated evaporator
-

When the second storage chamber is a freezing chamber, in order to decrease loss of the cool air, the drain pipe of the freezing chamber may use a siphon, that is, one part of the drain pipe of the freezing chamber is a U-shaped pipe, and is provided therein with water that blocks air passing. When the hot air entering into the freezing chamber is cooled to cause reduction of the air pressure in the freezing chamber, the air will enter into the freezing chamber from the refrigerating chamber through the exhaust pipe, thereby reducing a situation where too low pressure in the second storage chamber causes backflow of the water in the second drain pipe to make noise.
- Optionally, the exhaust hole is provided thereon with a water retaining device that blocks water in the first storage chamber from entering into the exhaust pipe, the exhaust pipe does not want water to enter therein, and disposing a water retaining device in the exhaust hole can reduce the possibility that water enters into the exhaust pipe.
- Optionally, the water retaining device is an exhaust hole cover that can allow air passing, and the exhaust hole cover can be provided with multiple small ribs used to guide water, to guide water to flow along walls of the first storage chamber, so as to avoid water entering into the exhaust pipe.
- Optionally, the exhaust pipe is internally provided with an air filtering device, to filter odors in the air passing through the exhaust pipe; as, in most cases, the air flows from the refrigerating chamber to the freezing chamber, and the air in the refrigerating chamber is easy to become odors, the air filtering device can avoid that odors in the refrigerating chamber enter into the freezing chamber.
- Optionally, the exhaust hole is formed on a vertical wall of the first storage chamber, and an opening direction of the exhaust hole is perpendicular to the vertical wall, so it is very difficult for the condensate water on the walls of the first storage chamber to enter into the exhaust pipe.
- The second drain pipe includes a U-shaped pipe, that is, part of the second drain pipe is siphon, to avoid that the cool air in the freezing chamber leaks out and avoids that external hot air enters into the freezing chamber along the second drain pipe.
- Optionally, the second storage chamber is internally provided with an evaporator, the second drain hole is located below the evaporator, and the second drain hole is used to discharge defrosting water of the evaporator.
- Optionally, a heater strip is disposed in a position that is on the second drain pipe and is near the second drain hole, to prevent the position that is on the second drain pipe and is near the second drain hole from frosting.
- Optionally, the heater strip is disposed on the second drain pipe in a winding manner.

FIG. 1 is a side sectional view of a refrigerator according to the present utility model; and -
FIG. 2 is a rear view of the refrigerator according to the present utility model. - Embodiments of the present utility model are elaborated below in combination with
FIGs. 1-2 . - This embodiment provides a double-door refrigerator 10having an up door and a down door, the
refrigerator 10 includes arefrigerating chamber 11 and afreezing chamber 12 located below the refrigeratingchamber 11, and the refrigeratingchamber 10 and thefreezing chamber 11 are separated through anadiabatic wall 13. - A refrigerating
chamber drain hole 5 is disposed in a position that is on a refrigerating chamberrear wall 14 and is near a refrigeratingchamber bottom wall 7, and condensate water on the refrigerating chamberrear wall 14 is collected to the refrigeratingchamber drain hole 5 and discharged via a refrigerating chamber drain pipe 6. - The
freezing chamber 12 is internally provided with an evaporator (not shown) that provides a cold source, a freezingchamber drain hole 17 used to collect defrosting water of the evaporator is disposed below the evaporator, and the collected defrosting water enters into the freezingchamber drain hole 17 and then is discharged via a freezingchamber drain pipe 21. - It can be seen from
FIG. 2 that a discharge section of the freezingchamber drain pipe 21 is a U-shaped siphon, which can prevent cool air in the freezing chamber from leaking out and block outside hot air from entering into the refrigeratingchamber 10. Water discharged by the freezingchamber drain pipe 21 can be directly discharged to the outside of the refrigerator or be discharged into a water pan located in a machine room of the refrigerator, and is evaporated by heat from a condenser or a compressor. - When a user opens the door of the
freezing chamber 12 to take an article, a lot of hot air will enter into thefreezing chamber 12 from the outside, the hot air is cooled in thefreezing chamber 12, due to the principle of heat expansion and cold contraction, the volume of the hot air decreases, so that pressure in thefreezing chamber 12 is reduced, and reduction of the air pressure in thefreezing chamber 12 will at least bring about two influences: 1. a pressure difference of two sides of the door of thefreezing chamber 12 increases, and the user requires a greater force to open the door; and 2. as the pressure in thefreezing chamber 12 is reduced, water in the siphon, under the action of atmospheric pressure, will flow to the direction of thefreezing chamber 12, and although it is very difficult for the water in the siphon to flow back to the freezing chamber due to the pressure difference, noise which is evident and easy to make the user perceive will be made during flowing. Based on the aforementioned disadvantageous influences, in this embodiment, anexhaust pipe 19 that allows air flow is disposed between the refrigeratingchamber 11 and thefreezing chamber 12, used to balance the pressure between the refrigeratingchamber 11 and thefreezing chamber 12. - An
exhaust hole 16 is disposed on arear wall 14 of the refrigeratingchamber 11, theexhaust pipe 19 is connected onto the freezingchamber drain pipe 21 through a three-way joint 1, so as to enable communication between the refrigeratingchamber exhaust hole 16 and the freezingchamber drain hole 17, and air can flow freely between the refrigeratingchamber 11 and thefreezing chamber 12. The size of theexhaust hole 16 is greater than that of the refrigeratingchamber drain hole 5. - The position of the
exhaust hole 16 is higher than that of the refrigeratingchamber drain hole 5 in a vertical direction, theexhaust hole 16 is provided thereon with anexhaust hole cover 2, theexhaust hole cover 2 has multiple small holes thereon to allow air passing, and in order to avoid that condensate water on the refrigerating chamberrear wall 14 enters into theexhaust hole 16, a surface of theexhaust hole cover 2 is provided with multiple ribs used to guide water. - As the refrigerating
chamber 11 is easy to smell bad when storing food therein, in order to prevent odors from entering into thefreezing chamber 12, anair filtering device 18 is disposed in theexhaust pipe 19, theair filtering device 18 can use a carbon bag with strong adsorption, and the carbon bag, in addition to absorbing odors in the air, can also adsorb a small amount of water vapor contained in the air entering into theexhaust pipe 19. Theair filtering device 18 is disposed on one side of theexhaust pipe 19 that is near the refrigeratingchamber exhaust hole 16, which can avoid that theair filtering device 18 is condensed due to absorbing water vapor. - The three-
way joint 1 divides the freezingchamber drain pipe 21 into two parts, the first part 3 of the freezingchamber drain pipe 21 is a section between the three-way joint 1 and the freezingchamber drain hole 17, and thesecond part 20 of the freezingchamber drain pipe 21 is a remaining part of the freezingchamber drain pipe 21 connected with the three-way joint 1. As the first part 3 of the freezingchamber drain pipe 21 is near thefreezing chamber 12, in order to prevent water coated on inner walls of the freezingchamber drain pipe 21 from condensing here to produce blockage, an outer wall of the first part 3 of the freezingchamber drain pipe 21 is wound with a heater strip for periodic heating. -
