Description

A Refrigerator

The present invention relates to a Bottom Freezer refrigerator having an ice making chamber formed on a door and a refrigerating chamber on an upper portion thereof. More specifically, the present invention relates to a Bottom Freezer refrigerator wherein a cold air generated by an evaporator installed in a refrigerating chamber is introduced into an ice- The present invention relates to a refrigerator freezer having uniform quality regardless of whether the door is opened or closed by a connecting pipe having a variable length when the door is opened or closed.

Generally, a refrigerator is a device intended for low-temperature storage of food. It is a household appliance that is frozen or refrigerated according to the state of the food to be stored. Currently, the refrigerator has various forms It is changing.

That is, an inner portion made of a polygon is formed inside the body, and a partition wall separating the upper and lower spaces is provided in the inner portion

A freezing chamber is formed in the upper portion and a freezing chamber is formed in the lower portion,

A plurality of doors are rotatably coupled to the front surface,

A bottom freezer refrigerator which can easily take out and use the food stored in the refrigerator without requiring the user to bend the waist has appeared,

According to the embodiment, the refrigerator in which the ice making facility is built on the door of the refrigerator compartment also appears.

However, in such a Bottom Freezer refrigerator, the evaporator of the freezer compartment at the bottom generates cold air by the heat exchange method, moves it along the flow path to the inside of the ice making chamber to generate ice, and at this time, Is moved back to the refrigerator room to store the article inside the refrigerator room at a low temperature. And the cold air in the refrigerating chamber is moved to the freezing chamber again to circulate the ice-making chamber, the refrigerating chamber, and the freezing chamber repeatedly.

Therefore, in the conventional bottom freezer refrigerator, the length of the flow path for moving the freezing chamber, the ice-making chamber, and the refrigerating chamber becomes long and it is difficult to control the cooling rate. Particularly, The power consumed due to the operation of the motor and the heat loss to cause the power to be increased, and the noise was inevitable. Also, in the conventional refrigerator, the refrigerating chamber located at the upper part has to be in a state of sufficient moisture to maintain the fresh state, and conversely, the freezing chamber must maintain the dry state because there is a problem such as sexual abuse. However, in the conventional refrigerator, the cold air in the high-humidity state in the refrigerating chamber is circulated to the freezing chamber, and the fresh air in the dry freezing chamber is moved to the refrigerating chamber through the ice making chamber and the moisture is insufficient. There was a problem that the freshness of the food dropped. Furthermore, the conventional bottom freezer refrigerator circulates between the refrigerator compartment and the freezer compartment in which doors with different cool air are installed, and the refrigerator compartment and the freezer compartment communicate with each other. Accordingly, when the door of the refrigerator room located at the upper side is tightly closed, air is introduced into the inside of the refrigerator compartment, and the inflow air is forced to open through the refrigerator compartment and into the freezer compartment. In addition, as the cold air moves between the freezer compartment and the ice-making compartment and the refrigerating compartment, there is a problem that the smell of food stored in the refrigerating compartment or the freezing compartment spreads throughout the refrigerator. In addition, although the dispenser is formed on the door at the time of constructing the ice making facility, the ice making room is installed with a separate space in the inside of the refrigerating chamber, so that the refrigerating space is narrowed.

Further, such a bottom freezer refrigerator is inevitably affected by the opening and closing of the door as the ice making chamber is formed in the door. Especially, when the door is opened, not only the cold air flows into the ice making chamber, There is a problem in that it can not help but be influenced by.
