the air in the first chamber enters the second chamber through the air supply outlet and returns to the first chamber through the air return inlet in a cooling circulation mode; or

And the dew removing mode is that air in the first compartment enters the dew removing air duct so that part of air flow flows to the front surface of the rear wall through the dew removing holes to remove surface dew.

Optionally, the dew-removing air duct has an inlet and an outlet communicating with the first compartment; and is

The refrigerator is configured to have the inlet and the outlet in a closed state and an open state, respectively, when in a cooling circulation mode; when in dew removing mode, the inlet and the outlet are both in an open state.

The refrigerator provided by the invention is a composite door refrigerator and can comprise a first door body and a second door body. After the first door body and the second door body are closed, the first lock catch and the second lock catch can be locked by the same stop piece, and are respectively locked by different stop pieces relative to the first lock catch and the second lock catch, so that the number of the stop pieces is reduced, the structure of the refrigerator is simplified, the cost of the refrigerator is saved, the assembly process of the refrigerator is simplified, and the assembly efficiency of the refrigerator is improved.

Furthermore, the first door body is specially designed, so that condensation on the inner wall of the second chamber can be effectively removed. Specifically, the rear wall of the first door body is hollow, a defrosting air channel is defined, and a plurality of dew removing holes are formed in the front surface of the rear wall backwards. When the second compartment needs normal refrigeration, the refrigerator operates a cooling circulation mode, so that air in the first compartment normally enters the second compartment through the air supply outlet to refrigerate the second compartment. When condensation is generated on the rear wall surface of the second compartment (namely the front surface of the rear wall of the first door body) and dew needs to be removed, the refrigerator operates a dew removing mode, so that air in the first compartment enters a dew removing air duct inside the rear wall of the first door body, and partial air flow flows to the front surface of the rear wall through dew removing holes. The relative humidity of the air in the dew removing air channel is necessarily lower than the original air flow at the front surface of the rear wall of the first door body (the relative humidity of the air near the dew is necessarily high), so the low-humidity air introduced into the dew removing air channel can promote the evaporation of the dew.

In addition, when the refrigerator operates in the dew-removing mode, the traditional modes of electrically heating the rear wall or introducing hot air and the like are not adopted, the dew is removed by utilizing the cold air of the first chamber, the dew-removing process basically does not influence the normal refrigeration of the second chamber, and the structural design is very ingenious.

Detailed Description

A refrigerator according to an embodiment of the present invention will be described with reference to fig. 1 to 10. Where the orientations or positional relationships indicated by the terms "front," "back," "upper," "lower," "top," "bottom," "inner," "outer," "lateral," and the like are based on the orientations or positional relationships shown in the drawings, the description is for convenience only and to simplify the description, and no indication or suggestion is made that the device or element so indicated must have a particular orientation, be constructed and operated in a particular orientation, and is therefore not to be construed as limiting the invention. The direction of the wind is indicated by arrows in the figures.

Fig. 1 is an exploded view of a refrigerator according to an embodiment of the present invention, and referring to fig. 1, the refrigerator according to an embodiment of the present invention may generally include a refrigerator body 101, a first door 102, a second door 103, a stopper 106, a first latch 104, and a second latch 105. The front side of the cabinet 101 (the side of the refrigerator where the first door 102 and the second door 103 are located is the front side of the refrigerator in the present invention, and the front-back direction is shown in the figure) is opened to define a first compartment 1011. The first door 102 is rotatably attached to the front side of the cabinet 101 to open and close the first compartment 1011 and defines a second compartment 1021. The second door 103 is rotatably installed at a front side of the first door 102 to open and close the second compartment 1021. The stopper 106 is mounted to the front side of the cabinet 101 adjacent to the hinge end of the first door 102. The first latch 104 is mounted on the first door 102 and adapted to be locked by the stopper 106 after the first door 102 is closed, so as to apply elastic resistance to the first door 102 when the first door 102 is opened, thereby preventing the first door 102 from being easily opened. The second latch 105 is mounted on the second door 103 and adapted to be locked by the stopper 106 after the second door 103 is closed, so as to apply elastic resistance to the second door 103 when the second door is opened, thereby preventing the second door 103 from being easily opened.

In the present embodiment, when the first door 102 is opened, the user accesses the articles from the first compartment 1011. When the first door 102 is closed and the second door 103 is opened, the user can access the articles from the second compartment 1021. Compared with the scheme that two door bodies are respectively provided with independent stop components in the existing structure, the refrigerator has the advantages that the first lock catch 104 and the second lock catch 105 can be locked by the same stop component 106 after the first door body 102 and the second door body 103 are closed, the number of the stop components 106 is reduced, the structure of the refrigerator is greatly simplified, the cost of the refrigerator is saved, the assembly process of the refrigerator is simplified, and the assembly efficiency of the refrigerator is improved.

Referring to fig. 2 to 4, in one embodiment of the present invention, the stopper 106 is a hook-shaped structure extending forward from the front side of the case 101 and then bent toward the other end of the case 101 in the transverse direction. The first latch 104 includes a first hook 1042 to hook on the stopper 106 when the first door body 102 is in the closed state, so as to be locked by the stopper 106.

In the process of opening the first door 102, the first hook 1042 is elastically deformed to disengage from the stopper 106, so as to allow the first door 102 to be opened smoothly. During the closing process of the first door 102, a user applies a backward pushing force to the first door 102 to urge the first hook 1042 to move toward the front surface of the stopper 106, so that the first hook is pressed along the front surface of the stopper 106 to elastically deform, and then enters the rear side of the stopper 106 to enter a locked position. Therefore, the position of the first hook 1042 is restricted by the stopper 106, so that the position of the first door 102 is very stable, and when the pulling force is insufficient and the first hook 1042 is not deformed enough to disengage from the stopper 106, the first door 102 cannot be opened.

The second locking catch 105 includes a second hook 1052 to hook on the stopper 106 when the second door 103 is in the closed state, so as to be locked by the stopper 106.

During the opening process of the second door 103, the second hook 1052 is elastically deformed to disengage from the stopper 106, so as to allow the second door 103 to be smoothly opened. When the second door 103 is closed, a user applies a backward pushing force to the second door 103 to urge the second hook 1052 to move toward the front surface of the stopper 106, so that the second hook is pressed along the front surface of the stopper 106 to be elastically deformed, and then the second hook enters the rear side of the stopper 106 to enter a locked position. Therefore, the position of the second hook 1052 is restricted by the stopper 106, so that the position of the second door 103 is very stable, and the second door 103 does not open when the second hook 1052 is not deformed enough to disengage the stopper 106 due to insufficient tension.

With continued reference to fig. 2 to 4, in an embodiment of the present invention, the stopper 106 extends while being bent toward the other lateral end of the housing 101 while being inclined rearward to facilitate hooking of the first hook 1042 and the second hook 1052 thereon.

Referring to fig. 3, in one embodiment of the present invention, the first locking device 104 and the second locking device 105 are respectively disposed on the upper and lower sides of the stopper 106. The first locking device 104 and the second locking device 105 are respectively located at the upper and lower sides of the stop member 106, so that the first locking device 104 and the second locking device 105 can be prevented from being influenced by each other, and the assembly process of the first locking device 104 and the second locking device 105 is simpler.

Referring to fig. 2 and 3, in one embodiment of the present invention, the stopper 106 further includes first and

second hinge shafts

1061 and 1062 extending from upper and lower surfaces thereof, respectively. The first door 102 is rotatably mounted on the first hinge shaft 1061. And the second door body 103 is rotatably mounted at the second hinge shaft 1062. The first hinge shaft 1061 and the second hinge shaft 1062 are respectively located on the upper surface and the lower surface of the stopper 106, so that the positions of the first hinge shaft 1061, the second hinge shaft 1062 and the stopper 106 can be more compact, the positions of the first door body 102 and the second door body 103 can be more compact, and the space occupied by the first door body 102 and the second door body 103 can be reduced.

In this embodiment, the stopper 106 not only serves to lock the positions of the door bodies (the first door body 102 and the second door body 103), but also serves as a part of the door body hinge structure. That is, the stopper 106 integrates the stopper function and the hinge function, and the structure is very skillful, thereby saving the cost of the refrigerator.

Referring to fig. 3 and 4, in an embodiment of the invention, the first lock 104 is provided with a first yielding hole 1041. The first hinge shaft 1061 passes through the first escape hole 1041. The second lock catch 105 is provided with a second yielding hole 1051. The second hinge shaft 1062 passes through the second escape hole 1051.

In this embodiment, in the process of closing the first door 102, the first latch 104 can be driven to rotate around the first hinge shaft 1061 and further rotate around the stopper 106, and in the process of closing the second door 103, the second latch 105 can be driven to rotate around the second hinge shaft 1062 and further rotate around the stopper 106, so that the first latch 104 and the second latch 105 can be locked by the stopper 106 relatively easily.

Referring to fig. 5, in an embodiment of the present invention, the first latch 104 is mounted on a bottom end surface of the first door body 102. The bottom end of the second door 103 has an ear plate 1031 extending rearward to below the first door 102. The secondary catch 105 is mounted to the upper surface of the mounting ear plate 1031.

In this embodiment, since the mounting ear plate 1031 extends to the lower side of the first door 102, the positional relationship between the first door 102 and the second door 103 can be more compact, and the second compartment 1021 of the first door 102 can be more tightly closed after the second door 103 is closed.

Referring to fig. 6, in some other embodiments, the stopper 106 is a hook-shaped structure extending forward from the front side of the case 101 and then bent toward the other end of the case 101 in the transverse direction to form a plurality of hooks. Specifically, for example, the stopper 106 is a hook structure extending toward the other lateral end of the case 101 to form a first hook 1063 and a second hook 1064. The first locker 104 may be hooked on the first hook 1063, and the second locker 105 may be hooked on the second hook 1064.

In some other embodiments, the refrigerator may refrigerate 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 1011 of the embodiment of the present invention is preferably a refrigerating compartment.

The existing double-door refrigerator often has the problem of condensation on the inner wall of a door chamber (the second chamber 1021 in the invention). The inventors have recognized that since the rear wall 211 of the first door body 102 is adjacent to the first compartment 1011 and the air in the first compartment 1011 can be transferred 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 1021, and condensation is more likely to occur.

Based on the above recognition, the embodiment of the present invention specifically designs the first door 102 to specifically remove dew from the front surface of the rear wall 211 of the second chamber 1021. Specifically, the rear wall 211 of the first door 102 is opened with an air supply outlet 212 and an air return outlet 214, both of which communicate with the first compartment 1011 and the second compartment 1021. The rear wall 211 of the first door body 102 is hollow, and defines therein a dew condensation removing duct 215 communicating with the first compartment 1011. 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 1021 and the dew-removing duct 215. The refrigerator is configured to: the cooling cycle mode can be set such that the air in the first compartment 1011 enters the second compartment 1021 through the supply outlet 212 and then returns to the first compartment 1011 through the return outlet 214, so as to cool the second compartment 1021 using the cool air in the first compartment 1011, as shown in fig. 7 and 8. Alternatively, the refrigerator is in a dewing mode in which air in the first compartment 1011 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. 9 and 10.

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 first door 102 after humid air is introduced or high humidity storage is placed due to door opening and closing operations, the refrigerator can be controlled to operate in the above-mentioned condensation removing mode, so that air in the first compartment 1011 enters the condensation removing air duct 215 inside the rear wall 211 of the first door 102, and a part of air flows to the front surface of the rear wall 211 through the condensation removing 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 first door body 102 (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.

When the refrigerator provided by the embodiment of the invention operates in the dew-removing mode, the traditional modes of electrically heating the rear wall 211 or introducing hot air and the like are not adopted, the dew is removed by utilizing the cold air in the first compartment 1011, the normal refrigeration of the second compartment 1021 is basically not influenced in the dew-removing process, and the structural design is very ingenious.

In some embodiments, as shown in fig. 7 and 9, the dew-removing air duct 215 may have an inlet 2151 and an outlet 2152 communicating with the first compartment 1011, so as to form an air path circulation between the dew-removing air duct 215 and the first compartment 1011, 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. 7 and 9, 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 1011 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 1011 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 first door body 102 is simplified, and the rear surface of the rear wall 211 of the first door body 102 only needs to be directly provided with the air supply outlet 212 and the air return inlet 214.

In some embodiments, as shown in fig. 7 and 9, 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 a cooling circulation mode, after the cold air flows into the second compartment 1021 from the air supply outlet 212, the cold air flows downwards due to the sinking effect of the relatively high density, and sequentially cools each height area of the second compartment 1021, and the air temperature gradually rises and then flows back to the first compartment 1011 from the air return opening 214 at the bottom of the second compartment 1021. Thus, more smooth air path circulation is formed, and the refrigeration effect of the second compartment 1021 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. 8 and 10, 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. 8) closing the inlet 2151 and opening the blast opening 212, or to a dewing state (fig. 10) 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. 8 and 10, 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. 8) or a dew-removing state (fig. 10). In the embodiment of the invention, the switching of the running modes of the refrigerator can be completed by controlling the rotation of one air door 216 without arranging a complex moving mechanism and control logic, and the structure and the control are greatly simplified.

In some embodiments, as shown in fig. 7 to 10, 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 1011 to flow to the air supply outlet 212 to accelerate the cooling cycle. Of course, for the case where the inlet 2151 communicates with the supply outlet 212, the fan 230 is also used to promote the air in the first compartment 1011 to flow to the dew-removing 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 first door body 102, and the closer to the air return port 214, the less condensation is generated. Therefore, the embodiment of the present invention specifically designs the arrangement density of the dew-removing holes 2154, and gradually decreases the arrangement density of the dew-removing holes 2154 in the direction from the air-supplying opening 212 to the air-returning opening 214 to match the variation trend of the dew condensation degree at different positions of the rear wall 211 of the first door body 102, thereby reducing the excessive meaningless openings. The opening area of the rear wall 211 of the first door body 102 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 illustrated and described in detail herein, many other variations or modifications consistent with the principles of the invention may be directly determined or derived from the disclosure of the present invention without departing from the spirit and scope of the invention. Accordingly, the scope of the invention should be understood and interpreted to cover all such other variations or modifications.
