The present invention will be described in detail below in conjunction with the embodiments shown in the figures. However, these embodiments do not limit the present invention, and structural or functional modifications made by those skilled in the art based on these embodiments are all included in the protection scope of the present invention.
The present invention relates to a door-in-door refrigerator. The refrigerator comprises a cabinet, and a door-in-door for closing the cabinet. The number of the door-in-doors is not limited.
Referring to
The first door body 10 comprises: a first door frame 11 and a transparent panel 13 embedded in the first door frame 11, and an internal space of the refrigerator can be observed through the transparent panel 13 which is for example a glass panel. The second door body 20 comprises: a second door frame 21, and parts such as bottle holders and shelves which are disposed on the second door frame 21 and configured to carry items, which are not described in detail here.
With reference to
In an implementation of the present invention, the display screen assembly 30 comprises: a display main body detachably connected to the second door body 20 and forming an accommodating space therein, a display screen 35 disposed on the display main body and forming the display interface, and a control panel that is at least partially disposed in the accommodating space of the display main body to control content output by the display screen 35; the display screen 35 may be a TFT screen to facilitate the user to control by touch, or a traditional screen which can be operated by using an external control button. A regulating frequency of the refrigerator is generally not very high. According to the present invention, the operating status of the refrigerator may be understood without opening the first door 10. If the content output by the display screen 35 needs to be regulated, the first door 10 may be opened to expose the display screen, and the display screen is regulated. As such, the overall effect of the transparent door is not destroyed, and meanwhile the appearance of the refrigerator may be made more concise.
In a preferred embodiment of the present invention, as shown in
In an implementation of the present invention, the display screen assembly 30 may be connected to the second door body 20 in a variety of ways, such as gluing, screw fixation, and snap connection.
As shown in
Preferably, a bottom wall of the first groove 333 is provided with a through hole 3333, and the elastic snap 335 comprises: an extension plate 3351 extending from a portion of the inner wall of the through hole 3333 towards a central position of the through hole 333, and an abutting stage 3353 which is disposed at an end of the extension plate 3351 adjacent to the central position of the through hole 3333 and extends towards an opening of the first groove 333. The first snap-fitting portion is formed between a side wall 33531 of the abutting stage 3353 and the first groove side wall 3331 of the first groove 333 away from the elastic snap 335.
In a process of assembling the display screen assembly 30 with the second door body 20, an external force presses the abutting stage 3353 so that the extension plate 3351 drives the abutting stage 3353 to move towards the interior of the through hole 3333. When the display screen assembly 30 moves to a mounting position relative to the second door body 20, the elastic snap 335 returns to the original position against the external force, and the outer wall of the second groove 211 abuts against the inner wall of the first groove 333 and the side wall 33531 of the abutting state 3353, whereby a structure that the first embedding portion is embedded into the first snap-fitting portion is formed so that the display screen assembly 30 is fixedly connected to the second door body 20.
In a preferred embodiment of the present invention, the first embedding portion is formed on the inner side wall of the second door frame 21; a third groove 213 sharing part of the side wall with the second groove 211 is protrusively outwardly provided on the inner side wall of the second door frame 21, an outer wall surface of the third groove 213 not sharing the side wall with the second groove 211 abuts against the inner wall surface of the first groove 333, the abutting stage 3353 is disposed corresponding to the third groove 213, and a portion of the extension plate 3351 not provided with the abutting stage 3353 is disposed corresponding to the second groove 211. With the third groove 212 being provided, the display screen assembly 30 can be more firmly installed on the second door body 20 through the cooperation of the first groove 333 and the third groove 213.
Further, in a preferred embodiment of the present invention, a fourth groove 215 sharing part of the side wall with the third groove 213 is disposed protrusively outwardly on the inner side wall of the second door frame 21, an outer wall surface of the fourth groove 215 not sharing the side wall of the third groove 213 abuts against the inner wall surface of the first groove 333, and a bottom wall of at least one of the fourth grooves 215 runs through the interior of the second door frame 21. The rear decorative plate 33 is provided with at least one accommodating hole 35 communicated with the accommodating space, and the accommodating hole 35 is disposed corresponding to the fourth groove 215 whose bottom wall runs through when the mounting of the display screen assembly 30 is completed.
Further, a communication member 2151 is further disposed at the bottom wall which is of the fourth groove 215 and runs through the interior of the second door frame 21. The shape of the communication member 2251 may be specifically set according to needs. For example, in an implementation of the present invention, the communication member 2151 has two communication paths for communicating the accommodating hole 35 with the interior of the second door frame 21: one communication path is used to guide a power line in the display screen assembly into the interior of the second door frame 21, and the other communication path is used to guide a heating pipe partially disposed in the accommodating space to enter the interior of the second door frame 21, the heating pipe being used to prevent a dew condensation phenomenon from occurring on the display screen assembly.
In a preferred embodiment of the present invention, the display screen assembly 30 is used to display an operation state of the refrigerator in real time, for example, a door opening or closing state of the refrigerator, a temperature of each compartment, etc.; further, the display screen assembly 30 is connected with a camera device in the refrigerator and used to display a state of foods in the refrigerator; in a specific example of the present invention, the door-in-door further comprises a sterilization module 40 which is detachably connected to the display screen assembly 30 and communicatively connected to the control panel to output its operation control instructions and control results through the display screen 35; the second door body 20 is further provided with an accommodating box 50 which is configured to accommodate items in cooperation with the sterilization module 40, and the sterilization module 40 is used to sterilize items in the accommodating box 50.
Preferably, the accommodating box 50 has an opening facing a side of the cabinet or the accommodating box is a drawer formed on the second door 20 and being pushable towards or pullable away from the cabinet of the refrigerator, thereby facilitating the user to put or take items.
It needs to be appreciated that the sterilization module 40 may also be configured as a moisturizing module or other functional modules that cooperate with the accommodating box 50, which is not described in detail here.
In summary, in the door-in-door with display screen assembly and the refrigerator having the same according to the present invention, the display screen assembly is disposed on the second door body arranged close to the cabinet, so that the operation state of the refrigerator may be learnt about without opening the first door body, which does not destroy the transparent display effect of the first door body and meanwhile may make the appearance of the refrigerator more concise.
