In this application.

Technical field

The invention relates to a control method for a multifunctional room in a refrigerator and a refrigerator, and belongs to the field of household appliances.

Background technique

The variety and quantity of food in consumers' homes are constantly changing. Therefore, for different foods, in order to achieve the best storage environment, the storage environment in the refrigerator needs to change accordingly. Since the optimal storage environment for different foods is different, usually a certain type of food has the most suitable temperature and humidity for storage. Raw meat prepared for cooking in a day or two is best stored at around -3 °C, while some dry matter, such as fungus, tea, etc., stored in refrigerated temperature, low humidity (35-50%) environment, can be preserved and preserved. The time is optimal. However, the humidity in the refrigerator in the existing ordinary refrigerator is greatly affected by the type of food stored, which makes the humidity in the refrigerator room fluctuate greatly, which is not conducive to storing dry matter.

In the storage of the refrigerator, the general refrigerator has a soft freezing compartment with a soft freezing function, the temperature of the soft freezing compartment is lower than that of the refrigerating compartment, and is higher than the freezing compartment, about 0 to -8 ° C, and the soft freezing compartment is generally It is installed in the refrigerator compartment of the refrigerator. For high-grade refrigerators, in addition to the soft freezing compartment, a drying chamber is provided, which provides a low-humidity storage environment. The soft freezer compartment consists of a soft freezer box, a heat shield that is placed on the soft freezer box for insulation, and a duct that blows in cold air. The heat insulation board is designed with a foaming layer with heat insulation function under the upper partition of the soft freezing box. The air duct is designed in the foam layer, and the air passage uniformly blows the cold air blown out from the evaporator to the soft from top to bottom. In the freezer compartment, the air in the compartment is cooled to soft freezing, and the heat insulation panel blocks the loss of cooling capacity and maintains the indoor soft freezing temperature. The existing drying chamber is also installed in the refrigerator compartment of the refrigerator, and the temperature of the drying chamber is changed by the temperature of the refrigerator compartment by 2 to 3 ° C, which is composed of a sealed drying box and a damper for air intake. The air inlet damper is connected to the air passage behind the back panel of the refrigerating chamber, and the dry cold air blown out from the evaporator is introduced into the box to replace the higher humidity air in the box, thereby reducing the humidity and temperature in the box. At the same time, the drying chamber is insulated by the foaming layer in the chamber, and the heat can be exchanged between the heat-conducting chamber wall and the air in the refrigerating chamber to increase the indoor temperature, thereby reducing the relative humidity in the chamber (Note: the absolute humidity is constant. In this case, the temperature rises and the relative humidity decreases.

However, due to the limited space in the refrigerated room, it is not ideal to design two separate rooms with different functions to occupy the space of the fruit and vegetable boxes. Therefore, it is necessary to design a structure that can switch between these two functions at any time as the needs of the consumer. Although the soft freezer compartment and the drying chamber are both designed in the cold room, the requirements for structural design are different. The temperature range of the soft freezer is: -3 to -8 °C. Relatively speaking, the soft freezer compartment needs better insulation. The drying chamber requires the purpose of sealing the compartment after the ventilation and dehumidification of the compartment, and at the same time, in order to achieve the low relative humidity value in the compartment, it is also necessary to satisfy the indoor air temperature value is not so low, so It is possible to obtain a higher relative humidity value under the condition that the absolute humidity value after the ventilation is constant, so that good heat exchange between the indoor and outdoor is required.

Therefore, the structural requirements of the soft freezing and drying chambers that achieve the same function are contradictory.

Summarized as follows:

Contradictory point	Soft freezer requirements	Drying room requirements
			Contradiction 1	Insulation (ie -3 to -8 ° C)	Heat exchange capacity (ie, achieving a higher temperature of the compartment air)
Contradiction 2	Fully ventilated (lower than the freezer compartment)	Seal after ventilation (to prevent humidity from rising)
