Furthermore, the temperature in the refrigerator compartment is too low, and the temperature of the refrigerator compartment cannot be maintained within a suitable range, thereby affecting the refrigerator compartment The normal working situation.
- first to eighth mating surfaces are to seal and prevent the leakage of cold air, that is, to prevent the cold air from flowing between the refrigerated refrigeration system and the ice-making refrigeration system. At the same time, to prevent the leakage of cold air to the outside of the refrigerator. In this way, the ice-making efficiency is greatly improved and the cooling efficiency in the refrigerator compartment of the refrigerator is effectively ensured.
- the cold air of the ice-making evaporator 2 is sent into the interior of the ice-making machine 1 by the ice-making fan 4 through the ice-making air supply duct 3. After the cold air is transferred into the ice-making machine 1, it will communicate with the ice-making machine 1 The air inside is subjected to heat exchange, and the cold air after the heat exchange is sent back to the ice making evaporator 2 through the ice making return air duct 5 to perform heat exchange again and circulate in turn.
- the setting of the ice-making fan 4 can speed up the flow rate of cold air, speed up the refrigeration cycle, and improve the refrigeration efficiency.
- the ice-making evaporator 2 since the ice-making evaporator 2 is provided in the refrigerator compartment and is located outside the ice-making room, by making the ice-making supply air duct 3 and the ice-making return air duct 5 both connected to the ice-making machine 1, the ice-making evaporator
- the defrost heating tube 10 in the evaporator 2 described below is away from the ice making room and the ice storage bucket in the ice making room, which reduces the heat transfer to the ice making room when the ice making evaporator 2 heats and defrosts, especially to the storage
- the heat transfer in the ice bucket prevents the ice cubes of the ice storage bucket from melting when heated and defrosted, which further improves the efficiency of ice making.
- the space in the refrigerating compartment is much larger than the space of the ice making compartment 2, it is convenient to install the ice making evaporator 2 and to increase the effective area of the ice making evaporator 2, and more reasonably match the heat load of the ice making machine 1 with
- the area of the ice making evaporator 2 increases the ice making speed of the ice making machine 1, increases the frost holding capacity of the ice making evaporator 2, reduces the heating and defrosting frequency of the ice making evaporator 2, reduces energy consumption, and improves the surface of the ice cube quality.
- an ice maker 1 and an ice making evaporator 2 are provided in the refrigerator compartment of the refrigerator, respectively, and the cold air is transported to the system through the short ice making air supply duct 3 through the ice making fan 4 provided at the back of the ice making room
- the ice making machine 1 in the ice compartment performs ice making, and the loss of cooling capacity is small on the way, and the ice making efficiency is guaranteed.
- the ice-making evaporator can be made in a case where the area of the ice-making evaporator 2 is constant The shape of 2 is changed from the original narrow and high to wide and short.
- the defrost heating tube 10 is located at the lower end of the ice making evaporator 2 as described below, the ice making evaporation is greatly reduced
- the heat transfer resistance of the evaporator 2 can transfer heat to the far end of the ice making evaporator 2 in the shortest time, reduce the heat transfer resistance of the ice making evaporator 2, shorten the defrosting time, and improve the defrosting efficiency.
