As shown in fig. 1 to 4, a refrigerator according to an embodiment of the present invention may generally include a refrigerator body 100 and a door body 200. Wherein, the front side of the cabinet 100 (the side of the door 200 is the front side of the refrigerator, and the front-back direction is shown in the figure) is opened to define the first compartment 101. The door body 200 includes a main door 210 for opening and closing the first compartment 101 and defining the second compartment 201, and a sub door 220 for opening and closing the second compartment 201.

The main door 210 may be rotatably mounted to the cabinet 100 at the front side of the cabinet 100, the front side of the main door 210 is opened to define the aforementioned second compartment 201, and the sub door 220 may be rotatably mounted to the main door 210 at the front side of the main door 210. When the main door 210 is opened, the user accesses the items from the first compartment 101. With the main door 210 closed and the sub-door 220 open, a user may access items from the second compartment 201.

The refrigerator may be refrigerated by a vapor compression refrigeration cycle, a semiconductor refrigeration system, or other means. Each compartment inside the refrigerator may be divided into a refrigerating compartment, a freezing compartment, and a temperature-changing compartment according to a refrigerating temperature. For example, the temperature in the refrigerated compartment is generally controlled between 2 ℃ and 10 ℃, preferably between 4 ℃ and 7 ℃. The temperature range in the freezer compartment is typically controlled between-22 ℃ and-14 ℃. The temperature-changing chamber can be adjusted between-18 ℃ and 8 ℃ to realize the temperature-changing effect. The optimal storage temperatures of different kinds of articles are different, and the storage compartments suitable for storage are also different. For example, fruit and vegetable foods are suitably stored in the refrigerating compartment, while meat foods are suitably stored in the freezing compartment. The first compartment 101 of the embodiment of the present invention is preferably a refrigerating compartment.

The embodiment of the utility model provides an in the refrigerator be composite door refrigerator, door body room (the utility model discloses a second room 201) inner wall condensation problem often appears in current composite door refrigerator. The inventor has recognized that since the rear wall 211 of the main door 210 is adjacent to the first compartment 101 and can transfer heat to the air in the first compartment 101 by heat conduction, the temperature of the front surface of the rear wall 211 is lower than that of the other wall surfaces of the second compartment 201, and condensation is more likely to occur.

Based on the above recognition, the embodiment of the present invention purposefully removes the dew on the front surface of the rear wall 211 of the second compartment 201 by specially designing the main door 210. Specifically, the rear wall 211 of the main door 210 opens a supply air outlet 212 and a return air outlet 214, both of which communicate the first compartment 101 and the second compartment 201. The rear wall 211 of the main door 210 is hollow, and a dew condensation removing duct 215 communicating with the first compartment 101 is defined therein. That is, the hollow space of the rear wall 211 constitutes the dew-removing duct 215. The front surface of the rear wall 211 is rearwardly opened with a plurality of dew-removing holes 2154 communicating the second compartment 201 and the dew-removing duct 215. The refrigerator is configured to: the cooling cycle mode may be set such that air in the first compartment 101 enters the second compartment 201 through the supply air outlet 212 and returns to the first compartment 101 through the return air outlet 214, so as to cool the second compartment 201 by using the cool air in the first compartment 101, as shown in fig. 1 and 2. Alternatively, the refrigerator is in a dewing mode in which air of the first compartment 101 enters the dewing duct 215 to allow a part of the air flow to the front surface of the rear wall 211 through the dewing holes 2154 to remove surface dews thereof, as shown in fig. 3 and 4.

In the embodiment of the present invention, the refrigerator is in the aforementioned cooling circulation mode in a normal state. However, when more condensation occurs on the front surface of the rear wall 211 of the main door 210 after humid air is introduced or a humid storage is placed due to a door opening and closing operation, the refrigerator may be controlled to operate in the above-described dewing mode such that air in the first compartment 101 enters the dewing duct 215 inside the rear wall 211 of the main door 210, and a part of the air flows to the front surface of the rear wall 211 through the dewing holes 2154. Since the relative humidity of the air in the dew-removing air duct 215 is necessarily lower than the relative humidity of the original air flow at the front surface of the rear wall 211 of the main door 210 (the relative humidity of the air near the dew is necessarily high), the low-humidity air introduced into the dew-removing air duct 215 can promote the evaporation of the dew, and the dew-removing process is completed. When dew removal is completed, the refrigerator can be controlled to switch to a cooling circulation mode.

The timing of switching between the cooling circulation mode and the dew condensation removing mode may be automatically controlled by the refrigerator, for example, by switching at regular time or automatically switching the operation mode of the refrigerator according to the detection result of the humidity sensor. The control can also be manual, for example, the user can manually switch the refrigerator operation mode when finding that dew removal is needed or stopping dew removal.

The utility model discloses refrigerator when the dew mode is removed in the operation, also do not adopt to carry out traditional modes such as electrical heating or introduction hot-air to back wall 211, still utilize the cold wind of first room 101 to remove dew, remove the dew process and can not produce the influence to the normal refrigeration of second room 201 basically, structural design is very ingenious.

In some embodiments, as shown in fig. 1 and 3, the dew-removing air duct 215 may have an inlet 2151 and an outlet 2152 communicating with the first compartment 101, so as to form an air path circulation between the dew-removing air duct 215 and the first compartment 101, and prevent the air flow for dew removal from accumulating near the dew-removing air duct 215 and the dew-removing hole 2154 and affecting the dew-removing effect. Further, the refrigerator is configured to have the inlet 2151 and the outlet 2152 in a closed state and an open state, respectively, when in a cooling circulation mode; when in dewing mode, both the inlet 2151 and the outlet 2152 are left open. That is, only the inlet 2151 of the dew-removing duct 215 needs to be closed in the cooling circulation mode. When in dew removal mode, the inlet 2151 of the dew removal duct 215 is opened. Since the opening and closing of the dew-removing air duct 215 are already controlled by controlling the opening and closing of the inlet 2151 and the outlet 2152 of the dew-removing air duct 215, the outlet 2152 of the dew-removing air duct 215 does not need to be controlled. In the two modes, the outlet 2152 of the dew-removing air duct 215 is in a normally open state and does not need to be controlled, so that the structure and control of the refrigerator are simplified.

In some embodiments, as shown in fig. 1 and 3, the inlet 2151 of the dew-removal duct 215 may penetrate the sidewall of the air outlet 212 to communicate with the air outlet 212. That is, the dew condensation removing duct 215 communicates with the first compartment 101 through the air blowing port 212, and does not need to be opened in the rear wall 211. The outlet 2152 of the dew-removing duct 215 may also penetrate the side wall of the return air inlet 214 to communicate with the return air inlet 214. That is, the dew condensation removing duct 215 communicates with the first compartment 101 through the return air opening 214, and does not need to be opened in the rear wall 211. The design structure is very ingenious, the opening structure of the rear wall 211 of the main door 210 is simplified, and the rear surface of the rear wall 211 of the main door 210 is only required to be directly provided with the air supply outlet 212 and the air return inlet 214.

In some embodiments, as shown in fig. 1 and 3, the supply and return

air ports

212 and 214 are located at the top and bottom of the rear wall 211, respectively. When the refrigerator is in the cooling circulation mode, after the cold air flows into the second compartment 201 from the air supply outlet 212, the cold air flows downward due to the sinking action of the relatively high density, and cools each height area of the second compartment 201 in turn, and after the air temperature is gradually increased, the cold air flows back to the first compartment 101 from the air return outlet 214 at the bottom of the second compartment 201. Thus, a more smooth air path circulation is formed, and the cooling effect of the second compartment 201 is improved. When the refrigerator is in the dew removing mode, the cold air enters the dew removing air duct 215 from the top of the dew removing air duct 215, and the cold air is more favorable for flowing downwards, so that the dew removing air duct 215 has better circulation and is favorable for accelerating the dew removing process.

As shown in fig. 2 and 4, the refrigerator may further include a damper 216 installed at the blast opening 212 and configured to be controllably moved to a cooling state (fig. 2) closing the inlet 2151 and opening the blast opening 212, or to a dewing state (fig. 4) opening the inlet 2151 and closing the blast opening 212. The embodiment effectively utilizes the advantage that the inlet 2151 is communicated with the air supply outlet 212, and utilizes one air door 216 to simultaneously control the air supply outlet 212 and the inlet 2151, thereby simplifying the air inlet and outlet control and having skillful design.

Specifically, as shown in fig. 2 and 4, one end of the damper 216 may be rotatably mounted at the front edge of the inlet 2151 to rotate to a cooling state (fig. 2) or a dew-removing state (fig. 4). The embodiment of the utility model provides an in, need not to set up complicated motion and control logic, only control the rotation of an air door 216, just can accomplish the switching of refrigerator operational mode, structure and control are all greatly simplified.

In some embodiments, as shown in fig. 1 to 4, the refrigerator further includes a blower fan 230, and the blower fan 230 is located at the air supply outlet 212 to promote air in the first compartment 101 to flow to the air supply outlet 212 to accelerate a cooling cycle speed. Of course, for the case where the inlet 2151 communicates with the supply outlet 212, the fan 230 is also used to force the air in the first compartment 101 to flow to the dew-removing air duct 215.

The inventors have recognized that the closer to the supply outlet 212, the more condensation is generated by the rear wall 211 of the main door 210, and the closer to the return outlet 214, the less condensation. Therefore, the embodiment of the present invention especially designs the arrangement density of the dewing holes 2154, and gradually reduces the arrangement density of the dewing holes 2154 in the direction from the air supply opening 212 to the air return opening 214 to match the variation trend of the condensation degree of the back wall 211 of the main door 210 at different positions, thereby reducing the excessive meaningless openings. The opening area of the rear wall 211 of the main door 210 may be spread over the entire front surface of the rear wall 211 to achieve sufficient dew removal, or may be spread over a portion of the front surface of the rear wall 211. The opening rate of the exposed hole 2154 can be 30-80%. The dewing holes 2154 may be arranged in a matrix or other arrangement. The dewdrop holes 2154 may be circular, oval, square, or other shapes. Preferably, the dew-removing hole 2154 is an elongated hole with the length direction parallel to the airflow direction of the dew-removing duct 215, and this structure is favorable for destroying the integrity of dew and accelerating the dispersion and evaporation of dew.

Thus, it should be appreciated by those skilled in the art that while a number of exemplary embodiments of the invention have been shown and described in detail herein, many other variations and modifications can be made, consistent with the principles of the invention, which are directly determined or derived from the disclosure herein, without departing from the spirit and scope of the invention. Accordingly, the scope of the present invention should be understood and interpreted to cover all such other variations or modifications.
