[0046] In addition, the refrigerator usually has a cabinet with a door body (refrigerator door) as a main body, and a freezing chamber, a refrigerating chamber or a storage chamber, and a drying chamber, an ice making chamber and the like divided in the cabinet, and has a condenser, an evaporator, a capillary tube and a compressor, a heat insulating member, a heat radiating member, a fan and the like, and the utility model does not make a detailed description of this. The utility model only makes a detailed description of the refrigerator door.
[0047] The refrigerator door related to the utility model will be described in detail below with reference to the drawings. Figure 1 It is the exploded perspective view of the main structure of the refrigerator door of the utility model (explosion diagram), Figure 2 It is the front view of the refrigerator door of the utility model, Figure 3 It is Figure 2 The schematic view of the part shown in the dashed box B in Figure 4 It is the top view (the view when observing from the upper direction to the lower direction of the refrigerator) in the state that the sensing device is installed on the substrate box.
[0048] As shown in Figure 1 And Figure 2 The refrigerator door D of the utility model mainly includes: a door frame body 1, a substrate box 2 arranged in the door body space S surrounded by the door frame body 1, a sensing device 3 fixed to the substrate box 2, and an atmosphere lamp (or lighting device) 4 arranged on the refrigerator door D.
[0049] Here, the sensing device 3 and the atmosphere lamp 4 are respectively electrically connected with a power supply substrate or a main substrate (or a power supply substrate) for controlling the whole refrigerator, and the sensing device 3 can sense or detect the existence of the refrigerator user and the change of the surrounding environment, for example, can sense or detect various conditions such as the existence of the refrigerator user passing by the refrigerator and the existence of the refrigerator user staying in front of the refrigerator. When the sensing device 3 senses and detects the change of the surrounding environment of the refrigerator, it sends an electric signal to the main substrate or the power supply substrate (not shown) of the refrigerator, and the main substrate or the power supply substrate sends an electric signal to the atmosphere lamp 4 electrically connected therewith, so as to turn on the atmosphere lamp 4 or change the brightness and / or color of the atmosphere lamp 4.
[0050] In addition, the atmosphere lamp can also be a lighting lamp or a lighting device or a light assembly that combines the atmosphere lamp and the lighting lamp. In addition, the atmosphere lamp can emit various colors and change colors in advance or at any time, and can be changed according to the user's settings, such as changing within a specified period or changing according to the change of the environment. In addition, the brightness of the atmosphere lamp can also be changed according to the user's settings, such as changing within a specified period or changing according to the change of the environment, and the utility model has no special limitation, which can be set and changed according to various conditions. In addition, the atmosphere lamp can also be set as a gradient light, which not only improves the technological sense of the refrigerator, but also improves the overall appearance of the refrigerator. In the utility model, the user can independently set the lighting conditions and lighting effects of the atmosphere lamp, so that the refrigerator door of the utility model is not only beautiful, but also can increase the interaction with the user.
[0051] In the substrate box 2, various components such as electronic components, control boards, display substrates, etc. can be installed. As a specific example, in the utility model, as shown in Figures 1 to 4 The sensing device 3 is fixedly installed in the substrate box 2. Among them, as an example of fixing the sensing device 3 to the substrate box 2, for example, a clamping piece can be used, more specifically, a clamping claw can be used. As shown in Figure 3 And Figure 4 As shown in the drawings, a clamping claw as a fixing piece can be provided on the left and right sides corresponding to the width of the sensing device 3, and the installation and fixation of the sensing device 3 can be achieved by embedding the sensing device 3 into the two clamping claws and clamping them. Here, the number of clamping claws is not limited, and in the drawings, one fixing piece with two clamping claws is taken as an example for illustration, but more than two can also be provided. In addition, there is no special limitation to the formation of the fixing piece 21 for fixing the sensing device 3, which can be formed integrally with the substrate box, or can be provided separately. From the perspective of cost, firmness and processing convenience, the fixing piece 21 is preferably a clamping piece (such as a clamping claw integrally formed with the substrate box 2 by molding or stamping, etc.) integrally formed with the substrate box 2, and is formed so that the sensing device 3 can be disassembled relative to the fixing piece (clamping piece) 21. By setting in this way, the number of parts can be reduced, thereby reducing the production steps, reducing the cost, and making the fixation of each part more firm and convenient to replace, easy to disassemble and convenient for fault repair. In addition, there is no limitation to the forming method of the clamping claw integrally formed on the substrate box 2, which can be extrusion molding or molding or stamping, etc.
[0052] In the refrigerator door D, a front panel and an inner container (not shown) are provided on the front side of the door frame body 1, and the refrigerator door is formed by foaming after combining these components, but in order to facilitate understanding of the description, the front panel and the inner container are omitted in the description and the drawings, and only the internal structure of the refrigerator door D is shown, which should be within the understanding of those skilled in the art.
[0053] In addition, the door frame body of the refrigerator is usually surrounded by one or more components (such as sheet components) and has a certain thickness in the longitudinal direction (when the user faces the refrigerator, the direction from the user side to the inside of the refrigerator). Herein, in order to facilitate understanding of the description, the space surrounded by the door frame body 1 is referred to as the door body space S (see Figure 1 and Figure 2 In the door body space S, mounting components, electronic components, etc. can be provided, but the present application does not have a special limitation.
[0054] In one embodiment of the present application, as shown in Figure 1 and Figure 2 A substrate pre-embedded box 5 is also provided in the door body space S, and the substrate box 2 can be installed and fixed by inserting the substrate box 2 into the substrate pre-embedded box 5.
[0055] In one embodiment, the door body space S is provided with a substrate pre-embedded box 5, and then the substrate box 2 is inserted into the substrate pre-embedded box 5 for installation and fixation after the substrate pre-embedded box 5 has been fixed and formed, and the installation of the atmosphere lamp 4 is performed, and then the substrate box 2 and the atmosphere lamp 4 are connected to the main substrate of the refrigerator. In this way, the installation accuracy and convenience of the substrate box can be improved, and the installation of the substrate box can be more secure. In addition, the present application fixes and installs the sensing device 3 in the substrate box 2 in advance, so that when the refrigerator door D is installed, the sensing device 3 does not need to be installed on the refrigerator door D, and only the substrate box 2 with the fixed and installed sensing device 3 needs to be inserted into the substrate pre-embedded box 5, thereby saving the installation steps and saving labor.
[0056] In addition, in one embodiment, the substrate pre-embedded box 5 is located at the upper portion of the door body space S, the atmosphere lamp 4 is located at the lower side of the door frame body 1 (for example, the lower portion of the door body space S or the lower side of the door frame body), and the main substrate is located at the top of the refrigerator (the upper portion of the refrigerator door when the refrigerator door is an upper side door). In addition, a hinge box 6 is further provided at the rotating pivot of the upper side of the door frame body 1, and the hinge box 6 has a wire harness hole 61 for the wire to pass through and a guide groove 62 for guiding the sliding of the component. The connection wire harness w1 of the induction device 3 and the connection wire harness w2 of the atmosphere lamp 4 (hereinafter, the connection wire harness w1 and the connection wire harness w2 are collectively referred to as the connection wire harness w) pass through the wire harness hole 61 of the hinge box 6 and are electrically connected to the main substrate located at the top of the refrigerator.
[0057] That is, taking the refrigerator door D as an example of the door body at the upper portion of the refrigerator, the atmosphere lamp 4 is located at the lower side of the refrigerator door D, the substrate pre-embedded box 5 and the substrate box 2 in which the induction device 3 is fixedly installed are located at the upper side of the refrigerator door D (above the door body space S), and the connection wire harness w1 of the induction device 3 and the connection wire harness w2 of the atmosphere lamp 4 pass through the wire harness hole 61 of the hinge box 6 at the upper side of the door frame body 1 as a whole (connection wire harness w) and are electrically connected to the main substrate at the upper side of the refrigerator, so that a separate wire outlet port is not required for the wire harness of the induction device 3, only one wire outlet port is required, and the connection wire harness w1 of the induction device 3 and the connection wire harness w2 of the atmosphere lamp 4 can be led out from the inside. In addition, by providing the wire harness hole 61 of the connection wire harness w2 in the hinge box 6, no other wire outlet port is required in the door body, the processing procedure is reduced, the structure of the hinge box 6 is ingeniously utilized, the overall appearance of the refrigerator door is neat and beautiful, and the installation is convenient.
[0058] In addition, in one embodiment of the present application, a radar is used as the induction device 3, so that the detection can be performed with higher precision and a wider induction range, and accurate detection can be performed even in the case of strong ambient light.
[0059] In addition, as one embodiment, when the refrigerator door D is observed from the front, the portion of the front panel that blocks the atmosphere lamp 4 can be formed as a light-transmitting portion through which light can pass. Of course, the atmosphere lamp 4 can also be directly arranged below the refrigerator door D.
[0060] As described above, in one specific embodiment of the present application, the refrigerator door D includes a door frame body 1, a substrate box 2 arranged in a door body space S surrounded by the door frame body 1, an induction device 3 fixed to the substrate box 2 by a fixing member 21 (such as a clamping member, for example, a clamping pawl), and an atmosphere lamp 4 arranged on the lower side of the refrigerator door D. In addition, a substrate pre-embedded box 5 is further arranged on the upper portion in the door body space S, the substrate box 2 can be inserted into the substrate pre-embedded box 5 to be fixed, and the connection wire harness w1 of the induction device 3 and the connection wire harness w2 of the atmosphere lamp 4 are both electrically connected to the main substrate through the wire harness hole 61 provided in the hinge box 6 on the upper side of the refrigerator.
[0061] Therefore, the induction device 3 is close to the main substrate, so that the wire harness arrangement distance of the induction device 3 is short, thereby saving costs. In addition, the induction device 3 is hiddenly arranged in the interior of the door frame body 1 (the rear portion or back surface of the front panel or glass plate), so that the induction device 3 cannot be touched and the appearance cannot be seen, thereby increasing the overall beauty of the refrigerator, and the induction device 3 is not easily damaged, prolonging the service life.
[0062] In addition, in the present application, a separate special fixing member for fixing the induction device 3 does not need to be arranged for the induction device 3, only when the substrate box is formed, the structure such as the clamping pawl is formed on the substrate box, for example, by integral molding, etc., so that the installation and fixation of the induction device 3 can be achieved. Therefore, additional components (such as plastic parts as separate fixing members) do not need to be added, the installation is convenient and more secure, and the installation process can be reduced, saving installation time.
[0063] In addition, in the present application, a radar is used as the induction device 3, so that the dynamic signal can be captured in a larger range, and the human motion can be more accurately identified. In addition, even if the thickness of the front panel is too thick, the external environment can be detected and perceived, and even in a complex light environment and during the day, accurate perception detection can be achieved.
[0064] In addition, in the present application, the wire harness hole 61 is ingeniously arranged in the hinge box 6, so that a separate opening does not need to be specially provided for wiring, which is convenient for installation and does not affect the appearance of the door body.
[0065] In addition, the user can independently set the lighting conditions and specific change conditions of the atmosphere lamp, which can increase the interaction between the user and the refrigerator, improve the sense of technology and the overall beauty of the refrigerator. In addition, the components are easy to disassemble, which is convenient for later maintenance and repair of faults.
[0066] The embodiments of the present application are described above, it should be understood that although the present application is described with respect to the specific embodiments, one skilled in the art can modify one or more features in the embodiments after reading the specification, without departing from the spirit and scope of the present application. Therefore, the specification is not intended to limit the present application.
