The utility model discloses a glass door 300 specially adapted composite door refrigerator. Fig. 3 is a schematic view of an assembly structure of a door body and a glass door 300 in a refrigerator according to an embodiment of the present invention; fig. 4 is a schematic view of a refrigerator according to an embodiment of the present invention in a cooling cycle mode.

As shown in fig. 3 and 4, the refrigerator is a composite door refrigerator, and specifically, the refrigerator includes a cabinet 100, a door 200, and a glass door 300. The front side of the case 100 is opened to define a first compartment 101. The door 200 is mounted to the cabinet 100 to open and close the first compartment 101, and the door 200 defines a second compartment 201 having an open front side. The glass door 300 is attached to the door body 200 to open and close the second compartment 201. The first compartment 101 of the embodiment of the present invention is preferably a refrigerating compartment. The front side of the door body 200 may be provided with a sealing tape 400 for sealing with the rear surface of the glass door 300. The magnet 500 may be further disposed at the front side of the door 200 to attract another magnet on the glass door 300, so that the glass door 300 is closed more tightly, and leakage of cold air is reduced.

The door 200 may be rotatably mounted to the cabinet 100 at a front side of the cabinet 100, the front side of the door 200 is opened to define the aforementioned second compartment 201, and the glass door 300 may be rotatably mounted to the door 200 at the front side of the door 200. When the door 200 is opened, the user accesses the articles from the first compartment 101. When the door 200 is closed and the glass door 300 is opened, the user can access the articles from the second compartment 201.

The second chamber 201 is opened and closed by a glass door 300 according to the embodiment of the present invention. Since the glass door 300 is more lightweight and thinner, it is more labor-saving for a user to open and close the second compartment 201. And the total thickness of the whole door body (comprising the door body 200 and the glass door 300) of the composite door refrigerator is not too thick, the weight is not too heavy, and the opening and closing of the whole door body are more labor-saving. In addition, because the outer frame 320 of the glass door 300 is of a half-frame structure, the visual field of a user is wider, more details in the second chamber 201 can be observed, and the product grade is improved.

FIG. 5 is an enlarged view at A of FIG. 4; FIG. 6 is a schematic view of the refrigerator shown in FIG. 4 in a dew removal mode; fig. 7 is an enlarged view at B of fig. 6, in which the wind direction is indicated by arrows.

The problem of condensation on the inner wall of a door compartment (the utility model relates to a second compartment 201) often appears in the existing composite door refrigerator. The inventors have recognized that since the rear wall 211 of the door 200 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 the temperature 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 door body 200. Specifically, the rear wall 211 of the door 200 is opened with an air supply outlet 212 and an air return outlet 214, both of which communicate the first compartment 101 and the second compartment 201. The rear wall 211 of the door 200 is hollow, and defines a dew condensation removing duct 215 communicating with the first compartment 101. 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 port 212 and returns to the first compartment 101 through the return port 214, so as to cool the second compartment 201 by using the cool air in the first compartment 101, as shown in fig. 4 and 5. 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. 6 and 7.

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 door body 200 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-mentioned condensation removal mode, so that air in the first compartment 101 enters the condensation removal air duct 215 inside the rear wall 211 of the door body 200, and a part of the air flow flows to the front surface of the rear wall 211 through the condensation removal 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 door body 200 (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. 4 and fig. 6, 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. 4 and 6, 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 door body 200 is simplified, and only the air supply outlet 212 and the air return inlet 214 need to be directly arranged on the rear surface of the rear wall 211 of the door body 200.

In some embodiments, as shown in fig. 4 and 6, 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. 5 and 7, 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. 5) closing the inlet 2151 and opening the blast opening 212, or to a dewing state (fig. 7) 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. 5 and 7, 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. 5) or a dew-removing state (fig. 7). 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. 4 to 7, 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 air blowing port 212, the more condensation is generated on the rear wall 211 of the door 200, and the closer to the air return port 214, the less condensation is generated. 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 rear wall 211 of the door 200 at different positions, thereby reducing the excessive meaningless openings. The opening area of the rear wall 211 of the door body 200 may be formed over the entire front surface of the rear wall 211 to achieve sufficient dew condensation removal, or may be formed 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.
