Definitions

  • This utility model relates to an electrical household appliance, in particular to an electric household refrigerator.
  • the deficiency of this improved design consists in the following: Since water is always stored in the U-shaped water storage kink, during the opening of the door by the user, the suction force resulting from the pressure difference between inside and outside can cause an upward movement of the defrost water from the U -keeping water accumulation kink in the drain pipe cause. The upwardly moving water returns to the U-shaped water storage kink after opening the door. The rising water and the returning water can cause rippling noise during the movement. This lack of noise is not desired by the designers of the refrigerator.
  • the aim of this utility model is to provide a refrigerator which can equalize both the pressure differential inside and outside the storage room as well as eliminate the noises of the defrosting water.
  • a refrigerator of one embodiment of this utility model comprises a cabinet body with an internal storage space and a movable door mounted on the cabinet body for opening and closing this inner storage space, in which cabinet body a drain pipe for draining the defrost water generated in this inner storage room is mounted to the outside of the cabinet body, on this drain pipe, a pressure compensation device for balancing the air pressure inside and outside the cabinet body is mounted, this pressure compensation device has a attached at the end of the drain pipe drainage and an attached near the end of the drain pipe air inlet device, this drain device the defrost water does not store and at the same time prevents external air from entering the drain pipeline.
  • a further improvement of this utility model is that the described drain pipe comprises a drain check valve mounted at the end of the drain pipe; that the drain check valve described comprises a connected to the end of the drain pipe connecting part and a protruding from the connecting part sealing part; the described sealing part comprises a soft pressed-material part with a sealing opening, which sealing opening can open under the force of gravity of the defrosting water.
  • the described air inlet device comprises a bypass line connected to the drain line and an air inlet check valve mounted at the end of the bypass line;
  • the described air inlet check valve comprises a valve seat fixed to the end of the bypass line and a valve seat mounted in the valve seat;
  • the described valve insert comprises a V-shaped leaf spring which bears against the inner wall of the air inlet channel of the valve seat, this leaf spring bending and deforming under the effect of the pressure difference inside and outside the cabinet body.
  • the efficiency of this utility model is as follows: By attaching the air inlet device on the drain pipe, it is possible when opening the door Introduce fresh air into the storage room and equalize the pressure difference between inside and outside.
  • the construction of the drainage device on the drainage pipe allows the end of the drainage pipe, on the one hand, to store no defrost water and, on the other hand, to prevent the ingress of outside air into the drainage pipe.
  • Figure 1 shows a three-dimensional schematic representation of a refrigerator of this utility model.
  • Figure 2 shows a schematic representation of a drain pipe with air inlet device and drain device of an embodiment of this utility model.
  • Figure 3 shows the sectional view of the drainage pipe from Figure 2.
  • a refrigerator of one embodiment of this utility model comprises a cabinet body 1, the cabinet body 1 having inside it a storage room divided into the freezer room and the cold store room. This storage room can be closed by the door 2.
  • the pressure compensation device 3 is attached in the lower rear part of the cabinet body 1. In this embodiment, the pressure compensating device 3 is used to equalize the pressure inside and outside the freezing space of the storage space of the cabinet body.
  • the pressure compensating device 3 includes the defrosting water drainage pipe 30, the downcomer attached to the end of the downcomer pipe, and the air inlet device mounted near the end of the downcomer pipe.
  • the upper end of the drain pipe 30 passes through the heat insulating foam layer 10 of the cabinet body and extends into the interior of the freezer compartment. Inside the freezer compartment there is an opening to collect the defrost water.
  • the lower end of the drain pipe 30 extends to the water receiving cup fifth
  • the drain device comprises a drain check valve 31 connected to the lower end of the drain pipe 30.
  • the drain check valve 31 comprises a connection part 32 connected to the end of the drain pipe and a seal part 33 projecting downwardly from the connection part.
  • the seal part 33 is made of soft pressed material. At the end of which creates by mutual contraction and close pressing a seal opening. When defrost water does not flow therethrough, this seal opening seals the drain check valve 31 and prevents the outside air from passing through the lower end of the drain pipe 30 into the freezer room. When defrost water flows to this seal opening, this seal opening can open under the gravity of the defrost water.
  • the advantage of this construction is the following: As long as defrost water flows to this seal opening, the defrost water can be discharged into the water intake tray 5 at any time, so that no defrost water is stored in the seal member 33.
  • the air inlet device includes a bypass line 34 connected to the downcomer 30 and an air inlet check valve 35 mounted at the end of the bypass line 34.
  • the air inlet check valve 35 includes a valve seat 36 secured to the end of the bypass line and a valve seat 37 mounted in the valve seat 36, the valve insert 37 a V-shaped leaf spring 38 which bears against the inner wall of the air inlet channel of the valve seat 35.

Abstract

La présente invention concerne un réfrigérateur comprenant un élément armoire qui présente un espace de stockage intérieur et une porte mobile montée sur l'élément armoire et permettant d'ouvrir et de fermer l'espace de stockage intérieur. Une conduite d'évacuation permettant d'évacuer vers l'extérieur de l'élément armoire l'eau de dégivrage apparaissant dans l'espace de stockage intérieur est montée dans l'élément armoire. Un dispositif de compensation de pression permettant d'équilibrer la pression atmosphérique à l'intérieur et à l'extérieur de l'élément armoire est appliqué sur cette conduite d'évacuation. Ce dispositif de compensation de pression comprend un dispositif d'évacuation placé à l'extrémité de la conduite d'évacuation et un dispositif d'admission d'air placé à proximité de l'extrémité de la conduite d'évacuation. Ce dispositif d'évacuation ne stocke pas l'eau de dégivrage et empêche également l'entrée d'air extérieur dans la conduite d'évacuation.
