Door body.

In another embodiment of the present invention, referring to FIG. 11 , the difference from the structure of the refrigerator shown in FIG. 1 is that the refrigerating air channel wind collecting section 111 does not have the refrigerating evaporator 9 and the corresponding refrigerating fan 15 , and is frozen. Between the air duct 14 and the refrigerating air duct wind collecting section 111, a damper 19 that controls the freezing air duct 14 and the refrigerating air duct to be opened or closed is provided. In the operation of the refrigerator of the present embodiment, if refrigeration is required inside the refrigerating compartment 10, the damper 19 is opened, and the amount of cold generated by the evaporator 6 is driven by the refrigerating evaporator 16, a part directly enters the freezing compartment 13, and the other part passes through the damper. 19 Entering the refrigerating air channel collecting section 111; wherein the cooling air flowing into the refrigerating air channel collecting section 111 can refer to the cooling air flow mode in the refrigerating air duct in the refrigerator shown in FIG.

Since the cold air in the refrigerating air passage of the present invention is dehumidified air treated by the evaporator (low humidity, usually relative humidity ≤ 35%), the cold air in the refrigerating air passage can be used to dry the inside of the drying chamber 3 to make the drying chamber 3 The humidity is kept to a low level (measured to maintain relative humidity ≤ 40%).

The refrigerator according to the present invention has a duct turntable 8, and during the cooling of the interior of the refrigerating chamber 10, the conduction state between the wind chamber 80 and the drying chamber 3 can be controlled by controlling the rotational position of the air duct dial 8, specifically the following description.

Specifically, in combination with the structure of the refrigerator shown in FIG. 1, the process of specifically implementing the drying function of the drying chamber 3 is as follows:

When cooling in the refrigerating compartment, the refrigerating fan 15 in the refrigerating air duct collecting section 111 starts to operate after a certain period of time after the refrigerating evaporator 9 is cooled, and simultaneously controls the blowing bobbin to enter the first rotating position shown in FIG. The cold air generated by the evaporator 9 is sent to the air chamber 80 of the air duct 8 for recirculation by the refrigerating fan 15, and the cold air in the air chamber 80 can enter the refrigerating chamber 10 and the drying chamber 3, respectively; The cold air in 80 is the air dehumidified and cooled by the refrigerating evaporator 9, and the humidity is low (humidity ≤ 35%), which satisfies the dry storage requirement of the drying chamber 3, and can keep the humidity inside the drying chamber 3 at a low level. (Measured to maintain humidity ≤ 40%).

After the internal temperature of the refrigerating compartment 10 is cooled for a period of time, when the internal temperature is lowered to the set temperature, the refrigerating evaporator 9 is cooled to stop, and at this time, the air blowing bobbin 8 is controlled to enter the second rotating position shown in FIG. 5, so that the wind chamber 80 is connected. The first air chamber air outlet 811 of the drying chamber 3 is closed to ensure that the high-humidity air in the air chamber 10 does not enter the first air chamber air outlet 811 during the humidification process of the refrigerator chamber 10 after the refrigeration evaporator 9 is stopped. The inside of the drying chamber 3 is used to affect the internal humidity. Specifically, the structure shown in FIG. 1 has a humidification procedure which is common in the refrigerator of the refrigerator compartment evaporator 15 during operation, that is, after the refrigerating evaporator 9 is stopped, the refrigerating fan 15 continues to operate, and the refrigerating evaporator 9 is condensed. The water vapor is blown into the refrigerating chamber 10 for humidification, and at the same time functions as a defrosting, and the air passage dial 8 enters the second rotational position shown in FIG. 5 to prevent the water vapor blown into the interior of the refrigerating chamber 10 from being blown through the drying chamber. The duct 4 enters the drying chamber 3.

In the specific process of drying the refrigerator, although the refrigeration evaporator 9 stops cooling, the humidity in the drying chamber 3 will increase to some extent, but before the next refrigerating evaporator 9 runs the cooling, the humidity inside the drying chamber 3 Still can meet the requirements, the measured maximum humidity ≤ 45%, in line with the humidity requirements of the drying chamber 3.

Based on the specific structure of the refrigerator according to the present invention, the cold air entering process inside the drying chamber on the door body can be effectively controlled, and the drying chamber is disposed on the door body, which can effectively reduce the influence on the refrigerating storage capacity of the refrigerating room, and is convenient for the user to Take the stored items inside the drying room.

When the first door body is closed, the drying chamber air inlet 31 is in communication with the air outlet air outlet 41, thereby achieving cold air from the refrigerating air. The road is conveyed to the inside of the drying chamber 3.

In a specific implementation process, the drying chamber air supply duct 4 is disposed in the heat insulating layer 12 near the inner side of the inner tank 100, thereby preventing the external environment temperature from unnecessarily affecting the cold air inside the drying chamber air supply duct 4, usually the drying room The heat insulating layer of the air supply duct 4 away from the side of the inner tank 100 is also at least 25 mm thick. Further, as a preferred embodiment, referring to FIG. 1, the air outlet duct air outlet 41 of the present invention is disposed on a side of the inner casing that is pivotally mounted adjacent to the first door body 2.

The protrusion 43 is embedded in the recess to enable positioning of the drying chamber air duct 4. Specifically, the heat insulating layer 12 is formed by foaming, and the protrusion 43 is embedded in the groove to prevent the position of the drying chamber air duct 4 from being displaced when the heat insulating layer 12 is foamed. In addition, in the case where the cross-sectional area of the drying duct air duct 4 is fixed, the manner of designing the boss portion 43 can also reduce the thinning occupation of the heat insulating layer 12 by the drying chamber air duct 4, which is reduced to some extent. Here the probability of condensation on panel 17 is generated.

As shown in FIG. 7 and FIG. 8 , in the specific embodiment, the heat insulating layer 12 is externally provided with a panel 17 exposed to the air, and the condenser tube 18 of the refrigerator extends to the vicinity of the drying chamber air supply duct 4 and is embedded in the heat preservation.
