Description

Technical Field

[0001] The present application belongs to the field of refrigeration technology, and in particular relates to a drawer assembly and a refrigerator. Background Art

[0002] Refrigerators that simply keep food fresh by refrigeration can no longer meet people's demand for higher quality preservation, so many more complex preservation methods have been developed. For example, an excitation coil is installed on the drawer of the refrigerator to improve the preservation effect by generating a magnetic field; another example is a temperature sensor installed on the drawer of the refrigerator to monitor the temperature in the drawer at all times, and cooperate with the heating coil to control the temperature in the drawer within a more stable range; there are even some drawers with display screens installed, and sensors installed in the drawers. When food is put in, the sensor detects the food being put in, records the current time, and then informs the user of the food storage time through the display screen. In all of the above schemes, electrical equipment (such as excitation coils, sensors or display screens, etc.) needs to be installed on the drawer of the refrigerator. However, the drawer needs to move when opening or closing it, and the drawer is prone to dirt and grime due to long-term storage of food, so it needs to be removed and cleaned regularly. It is precisely because of the need to ensure easy disassembly and assembly that how to electrically connect the electrical appliances on the drawer with the power supply equipment and control mechanism in the refrigerator has become a technical problem. Some technical solutions use slide rails for electrical connection, but friction during sliding will gradually cause the electrical connection to fail; some technical solutions use wireless connections, which are costly and have low power transmission efficiency, and can only achieve electrical connection at specific locations. Therefore, both of the above solutions are prone to electrical connection failure and have low reliability. In order to improve the user experience, a drawer assembly with more reliable electrical connection is needed. Utility Model Content

[0032] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0033] The embodiment of the present application provides a drawer assembly and a refrigerator to solve the problem of poor electrical connection reliability of the existing drawer assembly.

[0034] The drawer assembly provided in the embodiment of the present application can be applied to a refrigerator. For example, refer to Figure 1 , Figure 1 This is a schematic diagram of the structure of the refrigerator provided in the embodiment of the present application. Figure 2 , the drawer assembly can be installed in the cabinet 500 of the refrigerator.

[0035] In order to more clearly illustrate the structure of the drawer assembly, the drawer assembly will be introduced below with reference to the accompanying drawings.

[0036] refer to Figure 3The drawer assembly provided in the embodiment of the present application is applied to the box 500 of the refrigerator, and includes a guide rail 100, a drawer 200 and a wiring harness assembly. The guide rail 100 includes a base rail 110 and a mounting rail 120. The base rail 110 is used to be installed in the refrigerator, for example Figure 2 The wall surface of the refrigerator body 500 shown in the figure, or other side walls in the refrigerator, only needs to fix the relative position of the base rail 110 and the refrigerator to provide support for the mounting rail 120. The mounting rail 120 and the base rail 110 can slide relative to each other along the length direction of the base rail 110 to achieve opening and closing. The guide rail 100 is not limited to including the base rail 110 and the mounting rail 120, and can also include a structure such as an intermediate rail (not provided in the embodiment in the drawings) to form an existing rail structure such as a three-section ball bearing slide rail.

[0037] The drawer 200 is mounted on the mounting rail 120, so that the drawer 200 can slide along the mounting rail 120 to open or close. When the drawer 200 is in an open state, it can be exposed to the box 500; when the drawer 200 is in a closed state, it can be stored in the box 500. The drawer 200 is provided with an electric device to realize more functions of the drawer 200, such as strengthening the preservation of the contents, realizing human-computer interaction, etc.

[0038] The wiring harness assembly is used to electrically connect the electrical equipment on the drawer 200 with the power supply equipment and / or control equipment in the refrigerator. The wiring harness assembly includes a first wire 310, a first connection terminal 320, a second connection terminal 330 and a first bracket 340. The first connection terminal 320 and the second connection terminal 330 are respectively connected to the two ends of the first wire 310 for the first wire 310 to be electrically connected to other structures. The first connection terminal 320 is used to electrically connect with the box 500, which can be divided into two cases. The first case is that the wire body is provided with a socket, and the first connection terminal 320 can be directly inserted into the socket and electrically connected with the power supply equipment and / or control equipment of the refrigerator through the socket; the second case is that there is no socket on the box 500, and the first connection terminal 320 passes through the box 500 and is directly electrically connected with the power supply equipment and / or control equipment of the refrigerator. The second connection terminal 330 is installed on the first bracket 340, and the first bracket 340 is installed on the mounting rail 120, so that the second connection terminal 330 can move with the mounting rail 120. After the second connection terminal 330 is fixed in relative position to the mounting rail 120, it is very convenient to use the second connection terminal 330 to electrically connect to the electrical equipment. Because the electrical equipment is also fixed in relative position to the mounting rail 120, the second connection terminal 330 can be connected to the electrical equipment through a fixed wiring. At the same time, the connection method of the connection terminal is also very easy to disassemble, so it can provide a reliable electrical connection for the electrical equipment while being easy to disassemble. When the mounting rail 120 slides relative to the base rail 110, the first bracket 340 slides with the mounting rail 120 to drive the first wire 310 to retract. The first wire 310 can be wound on a coil spring. When the mounting rail 120 is Figure 5 The position shown is Figure 3 When the mounting rail 120 is moved from the position shown in FIG. 1 to the position shown in FIG. 1 , the first bracket 340 pulls the second connecting terminal 330 to pull the first wire 310, so that the first wire 310 is unwound from the coil spring and thus extends. Figure 3 The position shown is Figure 5 When the position shown slides, the first wire 310 is rewound onto the coil spring under the elastic force of the coil spring, thereby shortening.

[0039] refer to Figure 4 and Figure 6In some embodiments, the wiring harness assembly further includes a second wire 350, a second bracket 360 and a third connection terminal 370. The second bracket 360 is fixedly connected to the drawer 200, the third connection terminal 370 is connected to one end of the second wire 350, and the third connection terminal 370 is mounted on the second bracket 360, so that when the drawer 200 is mounted on the mounting rail 120, the relative position relationship between the third connection terminal 370, the second bracket 360, the second connection terminal 330 and the first bracket 340 is fixed. At the same time, the second bracket 360 is opposite to the first bracket 340. In this way, when the drawer 200 is mounted on the mounting rail 120 from a separated state, the second connection terminal 330 and the third connection terminal 370 can be connected by themselves. Since the second wire 350 is electrically connected to the electrical equipment, the above embodiment can make the electrical equipment more convenient to be electrically connected to the second connection terminal 330.

[0040] refer to Figure 7 and Figure 8 In some embodiments, the first bracket 340 is detachably connected to the mounting rail 120. Since the first bracket 340 needs to pull the first wire 310, it is often subjected to force and is easily damaged. The detachable connection between the first bracket 340 and the mounting rail 120 facilitates the replacement of the first bracket 340. When installing the drawer assembly, it is more convenient to first install the second connection terminal 330 on the first bracket 340 and then install the first bracket 340 on the mounting rail 120, thereby making the assembly of the drawer assembly easier.

[0041] refer to Fig. 9 and Fig.10 In some embodiments, when the mounting rail 120 slides in a direction away from the base rail 110 to be fully extended, the first bracket 340 is installed at one end of the mounting rail 120 close to the base rail 110, and the first bracket 340 is exposed outside the box 500. In the process of installing the drawer 200 on the mounting rail 120, the mounting rail 120 can be opened to the position as shown in FIG. Fig. 9 The first bracket 340 is in the expanded state shown, so that the mounting rail 120 is exposed outside the box 500, which facilitates the installation of the drawer 200 on the mounting rail 120. At this time, the first bracket 340 is exposed outside the box 500, which facilitates the connection of the electrical equipment with the second connection terminal 330 on the first bracket 340. The first bracket 340 is installed at one end of the mounting rail 120 close to the base rail 110 so that the first wire 310 pulled by the second connection terminal 330 is not exposed outside the box 500 as much as possible, thereby preventing the first wire 310 from being accidentally damaged during the installation process.

[0042] refer to Figure 7In some embodiments, the drawer assembly further includes a guide rod 400, and the guide rod 400 is parallel to the guide rail 100. The first wire 310 is configured as a spiral winding wire wound on the guide rod 400. When the mounting rail 120 slides relative to the base rail 110, the first bracket 340 slides with the mounting rail 120 and drives the first wire 310 to expand and contract along the guide rod 400. In this way, the elasticity of the first wire 310 itself can be used to complete the contraction, simplifying the structure that causes the expansion and contraction of the first wire 310, improving reliability while reducing costs.

[0043] refer to Figure 4 and Figure 8 In some embodiments, the first bracket 340 is provided with a slide groove 342, and the slide groove 342 extends along the extension direction of the guide rod 400. The side wall of the box body 500 is provided with a strip hole (at Figure 8 The side wall of the box body 500 corresponding to the strip hole is embedded in the slide groove 342 to cooperate with the slide groove 342. In this way, when the first bracket 340 slides with the mounting rail 120, the side wall of the box body 500 corresponding to the strip hole is always in cooperation with the slide groove 342, which can provide support for the first bracket 340, so that the first bracket 340 is supported by the side wall of the box body 500 and the mounting rail 120 at the same time, so that the first bracket 340 is not easily damaged.

[0044] refer to Figure 8 and Figure 4 In some embodiments, the first bracket 340 is provided with a guide protrusion 341 protruding in the direction of the guide rod 400, and the slide groove 342 is provided on the guide protrusion 341. The strip hole includes a guide hole 512 and a mounting hole 513. The mounting hole 513 is provided at one end of the guide hole 512 away from the opening of the box 500. The width of the mounting hole 513 is greater than the width of the guide hole 512, so that the guide protrusion 341 can pass through the mounting hole 513. At the same time, during the sliding process of the first bracket 340, the side wall of the box 500 corresponding to the guide hole 512 can cooperate with the slide groove 342 to provide support. The reason why the mounting hole 513 is provided at the end of the guide hole 512 away from the opening of the box 500 is that when the first bracket 340 moves to this end, the first wire 310 is in a contracted state, so the force of the first wire 310 on the first bracket 340 is smaller; at this time, the first bracket 340 is not easily damaged when it loses the support of the guide hole 512.

[0045] The embodiment of the present application also provides a refrigerator, in which the drawer assembly provided by the present application is installed in the refrigerator body 500.

[0046] refer to Figure 7 and Figure 8In some embodiments, a through hole is provided on the side wall of the box body 500, and a wire accommodation space is provided on the side of the through hole away from the accommodation cavity. The first wire 310 is accommodated in the wire accommodation space, and the second connection terminal 330 is installed on the first bracket 340 through the through hole. The through hole may not be Figure 8 The mounting hole 513 and the guide hole 512 in the drawer 200 may be a round hole, through which the first wire 310 passes. A structure that allows the first wire 310 to be retractable (such as the coil spring provided in the above embodiment) may also be provided in the wire accommodation space. In this way, the first wire 310 can be accommodated in the wire accommodation space, and is not likely to rub against the drawer 200, thereby protecting the first wire 310.

[0047] refer to Figure 2 , Figure 7 and Figure 8 In some embodiments, the refrigerator includes a partition 510, and the partition 510 is used to form a side wall of the box body 500 away from the outer wall of the refrigerator. The capacity line space is set in the partition 510, and the strip hole is set on the surface of the partition 510 facing the drawer 200. The outer wall of the refrigerator is often provided with a heat insulating material to prevent the outside heat from entering the refrigerator and affecting the refrigerator refrigeration. Therefore, the capacity line space is set in the partition 510, and it does not need to be set in the outer wall of the refrigerator. The occupation of the space for setting the heat insulating material by the capacity line space is avoided.
