Problems solved by technology

[0013] Moreover, when new food with a temperature higher than that in the weak freezing temperature zone is put in, as the indoor temperature rises, the temperature of the frozen food that has been stored in the weak freezing temperature zone also rises, and the taste and freshness of the food will decrease. The problem

[0093] Figure 9 It is a schematic diagram explaining the piping structure of the said 1st Embodiment, Figure 10 It is a schematic diagram of the pipeline structure of the modification example 1.

[0094] The first embodiment of the present invention is as Figure 9 As shown, the cold air generated from the freezing cooler 27 is blown upward by the cooling fan 28 through the cold air duct 30 , and is blown into the ice making chamber 12 by the ice making fan 31 . Such as Figure 10 As shown, the cold air generated by the freezer cooler 27 is blown into the freezer compartment 9 by the freezer fan 28, and the air in the freezer compartment is blown into the ice maker compartment 12 by the ice-making fan 31 through a pipeline arranged at the rear of the freezer compartment.

[0095] In addition if Figure 11 As shown, the cold air generated by the refrigeration cooler 27 may also be blown to the ice-making chamber 12 by the ice-making fan 31 after passing through the pipeli...

[0097] During the ice-making process of the automatic ice-making device, in addition to the defrosting mode, the fan 31 for ice-making must be operated.

[0098] During the defrosting operation, the temperature of the cooler 27 for freezing is relatively high. If the air in the higher temperature environment is blown into the ice-making chamber 12, the indoor temperature will rise significantly. Not only the ice-making time will be prolonged, but also the stored Ice will melt. Also, in the refrigeration mode, although the freezing cooler 27 is not cooled, the temperature of the cooler is kept at a low temperature, and the ice making compartment 12 continues to be cooled by operating the ice making compartment fan 31 .

[0099] Therefore, in addition to the defrosting mode, the ice making compartment fan 31 is operated even when it is not in the freezing mode, so that the ice making time can be shortened and the temperature inside the box can be reliably maintained.

[0101] In the refrigeration mode, the ice-making fan 31 is operated at a low speed, and in the freezing mode, the ice-making compartment fan 31 is operated at a high speed.

[0102] In the refrigerating mode, since the freezer cooler 27 is not cooled, the difference from the normal high-speed operation is small regardless of whether the ice-making fan 31 rotates at a high speed or at a low speed. Therefore, by operating the ice-making fan 31 at a low speed in the refrigeration mode, the ice-making compartment 12 can be reliably cooled while saving power.

Abstract

A refrigerator comprises a refrigerating room(5)disposed in the upper part of a refrigerator body; a freezing room (9) disposed in the lower part of a refrigerator body; a vegetable room(7) provided between the refrigerating room and the freezing room; the ice making room (12) disposed in the corner of the bottom part of the refrigerating room having an automatic ice making device; and an ice making fan(31) provided in the rear part of the ice making room; The cooling air produced by the refrigeration cooler is sent to the ice making room via a duct(30) and the ice making fan(31), and a cooling air duct including the freezing fan and a return duct from the ice making room are jointly provided in the rear surface of the vegetable room; A weak freezing chamber (6) is disposed in a freezing space (40), and a damper (37) is disposed in a back face of the weak freezing chamber (6). wall in a freezing space (40) and a damper (37) is disposed in a back face of the weak freezing chamber (6). When weak freezing is performed for food in the weak freezing chamber (6), the damper (37) is made into an open state, cooling air is forced to flow in, resulting in a rapid freezing operation up to a maximum ice crystal generation zone or lower. Subsequently, a heater (43) is initiated and the food is maintained in the weak freezing temperature zone. The present invention provides a layout of a storage room of a usability, Furthermore, it may maintain fresh degree and taste of food with weak frozen temperature when preserving food.

Description

technical field [0001] The invention relates to a cooling storage room of a refrigerator, in particular to a structure and a control method of an ice-making room, and a control method of a weak freezing room. Background technique [0002] In recent years, with the diversification of people's life, the capacity of refrigerators has become larger. Considering the frequent opening and closing of the door and the high frequency of use, the refrigerator with the largest volume of storage is arranged on the upper part of the refrigerator body, and the lower part is arranged Vegetable room and freezer room, at the same time, an ice-making room with an ice-making device and a temperature switching room that can switch the temperature in the box from freezing temperature to vegetable storage temperature into multiple temperature zones are usually set between the vegetable room and the freezer room. [0003] Because it is necessary to set up multiple storage rooms with different stora...
