Definitions

  • the present utility model relates to the field of household appliances, and particularly to a refrigerator.
  • 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.
  • 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.
  • 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
  • JP S55 162082 U also contains relevant prior art.
  • the present utility model provides a refrigerator that can improve users' product experience.
  • the present invention provides a refrigerator as defined in claim 1, including a first storage chamber and a second storage chamber, wherein a set temperature of the first storage chamber is higher than that of the second storage chamber, the first storage chamber has a first drain hole and a first drain pipe connecting the first drain hole, and the second storage chamber has a second drain hole and a second drain pipe connecting the second drain hole, and further including an exhaust pipe, wherein the first storage chamber has an exhaust hole, the exhaust pipe is connected with the second drain pipe and the exhaust hole is in communication with the second drain hole.
  • the first storage chamber may be a refrigerating chamber or a zero degree chamber
  • the second storage chamber may be a freezing chamber
  • the exhaust hole of the first storage chamber is in communication with the second drain hole of the second storage chamber, when air pressures in the first storage chamber and the second storage chamber are not equal, air will flow from a high-pressure compartment to a lower-pressure compartment, so as to balance the air pressure between the first storage chamber and the second storage chamber.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • the heater strip is disposed on the second drain pipe in a winding manner.
  • a three-way joint is further included, and the exhaust pipe is connected to the second drain pipe through the three-way joint.
  • the first storage chamber is a refrigerating chamber
  • the second storage chamber is a freezing chamber

  • a refrigerating chamber drain hole 5 is disposed in a position that is on a refrigerating chamber rear wall 14 and is near a refrigerating chamber bottom wall 7, and condensate water on the refrigerating chamber rear wall 14 is collected to the refrigerating chamber 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 freezing chamber drain hole 17 used to collect defrosting water of the evaporator is disposed below the evaporator, and the collected defrosting water enters into the freezing chamber drain hole 17 and then is discharged via a freezing chamber drain pipe 21.
  • an evaporator not shown
  • a freezing chamber drain hole 17 used to collect defrosting water of the evaporator is disposed below the evaporator, and the collected defrosting water enters into the freezing chamber drain hole 17 and then is discharged via a freezing chamber drain pipe 21.
  • a discharge section of the freezing chamber 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 refrigerating chamber 10.
  • Water discharged by the freezing chamber 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.
  • an exhaust pipe 19 that allows air flow is disposed between the refrigerating chamber 11 and the freezing chamber 12, used to balance the pressure between the refrigerating chamber 11 and the freezing chamber 12.
  • An exhaust hole 16 is disposed on a rear wall 14 of the refrigerating chamber 11, the exhaust pipe 19 is connected onto the freezing chamber drain pipe 21 through a three-way joint 1, so as to enable communication between the refrigerating chamber exhaust hole 16 and the freezing chamber drain hole 17, and air can flow freely between the refrigerating chamber 11 and the freezing chamber 12.
  • the size of the exhaust hole 16 is greater than that of the refrigerating chamber drain hole 5.
  • the position of the exhaust hole 16 is higher than that of the refrigerating chamber drain hole 5 in a vertical direction, the exhaust hole 16 is provided thereon with an exhaust hole cover 2, the exhaust hole cover 2 has multiple small holes thereon to allow air passing, and in order to avoid that condensate water on the refrigerating chamber rear wall 14 enters into the exhaust hole 16, a surface of the exhaust hole cover 2 is provided with multiple ribs used to guide water.
  • an air filtering device 18 is disposed in the exhaust pipe 19, the air 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 the exhaust pipe 19.
  • the air filtering device 18 is disposed on one side of the exhaust pipe 19 that is near the refrigerating chamber exhaust hole 16, which can avoid that the air filtering device 18 is condensed due to absorbing water vapor.
  • the three-way joint 1 divides the freezing chamber drain pipe 21 into two parts, the first part 3 of the freezing chamber drain pipe 21 is a section between the three-way joint 1 and the freezing chamber drain hole 17, and the second part 20 of the freezing chamber drain pipe 21 is a remaining part of the freezing chamber drain pipe 21 connected with the three-way joint 1.
