Detailed Description

A refrigerator is a type of refrigeration equipment that maintains a constant low temperature, and generally includes a cabinet for accommodating an article to be refrigerated, a compressor, an ice maker, and the like. A common household or commercial refrigeration unit is typically a refrigerator or freezer.

In the prior art, a light source is generally arranged at the top in a box body to realize illumination of the box body, so that a refrigerated article can be conveniently taken and placed. The rack comprises a plate body on which refrigerated goods are placed, and the plate body is detachably arranged inside the box body. The relative both sides of plate body are configured with the courage muscle cooperation on the lateral wall of box so that the plate body demountable installation is in the box, promptly, the plate body need be along the courage muscle pack in the cold storage plant, take out from the cold storage plant along the courage muscle.

However, there are many problems with this type of installation of lighting and racks, for example, the space between the racks is fixed and cannot be adjusted, which results in the space of the cabinet not being well utilized; the length of the liner rib is the same as that of the side wall of the box body, namely the liner rib is longer, the rack is heavier, the long-distance push-pull causes that the rack is more laborious to install and dismantle, and the two opposite sides (namely the installation side) of the rack and the side wall of the box body are damaged; the side wall of the box body is not beautiful enough.

In view of the above, the present embodiment provides a rack for a refrigerator, fig. 1 is a schematic view of a refrigerator to which the rack is applied according to an embodiment of the present invention, and fig. 2 is a schematic view of a back panel to which the rack is applied according to an embodiment of the present invention. As shown in fig. 1, the refrigerating apparatus includes a cabinet 100, two support rails 200, and a rack 300. The cabinet 100 defines a storage compartment 110 therein.

The two support rails 200 are disposed on the back plate 120 of the box body 100 and extend along the height direction of the box body 100, and a plurality of support portions are distributed along the height direction of each support rail 200. The electrodes are respectively disposed in the two support rails 200.

As shown in fig. 2, the rack 300 includes a plate body 310, two fixing pieces 320, and a lighting assembly 330. The two fixing members 320 are respectively disposed on two opposite sides of the board body 310, that is, as shown in fig. 1 and 2, the two fixing members 320 are respectively disposed on the left and right sides of the board body 310. And one ends thereof facing the supporting parts are configured to be detachably disposed at the supporting parts of the two support rails 200, respectively, that is, the rear sides of the plate bodies 310 are configured to be detachably disposed at the two support rails 200, so as to mount the rack 300 at different heights of the refrigerator. It should be apparent that the mounting of the rack 300 in fig. 1 and 2 is merely exemplary and not the only mounting means, e.g., the rack can be mounted from either the left or right side of the support rail.

The lighting assembly 330 is disposed on one side of the board body 310 close to the supporting portion and is erected between the two fixing members 320, that is, the lighting assembly 330 is disposed on the rear side of the board body and is overlapped between the two fixing members. The lighting assembly 330 has two conductive contacts respectively protruded toward the two electrodes, which are respectively inserted into the two support rails 200 to contact the electrodes when the rack 300 is mounted in the refrigerator, so as to supply power to the lighting assembly using the electrodes to emit light to the panel body. It is clear that the way in which the conductive contacts and the electrodes are contacted in fig. 1 and 2 is only exemplary and not the only way of mounting, e.g. the conductive contacts are contacted with the electrodes from the left or right side of the support rail. One of the two electrodes is a positive electrode, the other one is a negative electrode, and the two conductive contacts of the lighting assembly 330 are respectively in contact with the positive electrode and the negative electrode to form a complete lighting assembly power supply loop.

The two support rails 200 are respectively provided with a positive electrode and a negative electrode, the lighting assembly 330 is provided with two conductive contacts, and the two conductive contacts of the lighting assembly 330 are respectively contacted with the positive electrode and the negative electrode to form a complete power supply loop. This arrangement allows the two conductive contacts to be electrically connected to the positive and negative electrodes, respectively, with precision, avoiding short circuits, and allowing the rack 300 and the two support rails 200 to be mounted relatively easily.

A plurality of supporting portions are distributed along the height direction of each supporting rail 200, and the racks 300 are detachably disposed at the supporting portions of the two supporting rails 200 so that the racks 300 are installed at different heights of the refrigerating apparatus. The technical problem that the space between the racks 300 is fixed and cannot be adjusted, so that the space of the box body cannot be well utilized is solved.

The rack 300 is mounted on the refrigerating device by the fixing parts 320 at both sides of the board body and the supporting part on the supporting rail 200. Avoiding the long-distance pushing and pulling of the rack 300 causes the installation and removal of the rack 300 to be laborious and damages to the opposite sides (i.e., the installation sides) of the rack 300 and the side walls of the cabinet 100.

The rack 300 includes an illumination assembly 330, and the illumination assembly 330 is disposed at the rear side of the panel body to solve the technical problem of condensation.

The two support rails 200 are respectively provided with electrode bars therein, and the lighting assembly 300 has two conductive contacts which are respectively inserted into the two support rails 200 to be in contact with the electrodes when the rack 300 is installed at different heights of the refrigerator, so that the lighting assembly 300 is supplied with power by the electrodes to emit light to the panel body. Therefore, as the rack 300 moves, the illumination assembly 330 also moves along with the rack 300 and can connect the electrodes from different positions, thereby solving the technical problem that the rack 300 has illumination blind areas.

The electrodes are positioned in the supporting guide rail 200, the conductive contacts are inserted into the supporting guide rail 200 and are contacted with the electrodes to obtain power supply, the mounting parts of the two fixing parts for bearing the rack 300, the mounting parts and the conductive contacts of the lighting assembly are separated, the conductive contacts cannot be damaged due to bearing and repeated mounting, namely, the electrodes cannot be damaged due to external force, and electric shock cannot be caused by mistake.

FIG. 3 is a schematic diagram of a rack structure according to one embodiment of the present invention; FIG. 4 is a schematic diagram of a rack configuration from another perspective according to an embodiment of the present invention. In some embodiments, as shown in fig. 3 and 4, the rack 300 includes a plate body 310, two fixtures 320, and a lighting assembly 330. The two fixing members 320 are respectively disposed on two opposite sides of the board body 310, that is, the fixing members 320 are disposed on the left and right sides of the board body 310. Each of the fixing members 320 is adapted to cooperate with the inner supporting portion of the refrigerator to detachably mount the rack 300 to different heights of the refrigerator. The lighting assembly 330 includes a light shield 332 and a light source 335, the light shield 332 is disposed on one side of the board body 310 close to the supporting portion, and is erected between the two fixing members 320, and a light-transmitting through slot 3321 is formed therein. That is, the light shield 332 is disposed at the rear side of the plate body 310, and the fixing member 320 is disposed at both sides of the plate body 310. The light source 335 is disposed on a side of the light shield 332 opposite to the plate body 310, and emits light to the plate body 310 through the light-transmitting through slot 3321. That is, the light source 335 is disposed at the rear side of the light shield 332, the plate body 310 is disposed at the front side of the light shield 332, a light-transmitting through slot 3321 is formed in a portion of the light shield 332 located between the light source 335 and the plate body 310, and the light source 335 emits light to the plate body 310 through the light-transmitting through slot 3321.

Therefore, the light source 335 is disposed on a side of the light shield 332 opposite to the plate body 310, that is, the light source 335 and the plate body 310 are disposed on two sides of the light shield 332 facing away. This arrangement prevents the light source 335 from directly contacting the board 310, so as to prevent the light source 335 from affecting the assembly of the board 310 and the fixing member 320 and affecting the fixing of the board 310. Another convenience is that the damage of the light source 335 caused by applying an external force to the light source 335 during the bearing process of the plate body 310 is also avoided.

The light source 335 makes the plate body 310 emit light through the light-transmitting through slot 3321, so as to prevent the light source 310 from directly irradiating eyes, and make the light softer. And light passes through plate body 310 and outwards gives out light, makes plate body 310 luminous compare the line source and the point light source more even, reduces the blind area.

The lighting assembly 330 is disposed at the rear side of the plate 310, and along with the movement of the position of the rack 300, the lighting assembly 330 also moves along with the rack 300 and can be connected with the electrodes from different positions, thereby solving the technical problem that the rack 300 has a lighting blind area.

In some embodiments, as shown in fig. 3 and 5, the illumination assembly 330 further comprises a light leakage prevention plate 336: the light leakage prevention plate 336 extends out from the side surface of the light shield 332 opposite to the plate body 310 and is positioned below the light transmission through groove 3321, and the edge of the plate body 310 is lapped on the light leakage prevention plate 336 to prevent the light of the light source 335 from leaking out from the lower part of the plate body 310. The lighting assembly 330 further includes two plate body limiting blocks 337, the two plate body limiting blocks 337 respectively extend from the light shield 332 opposite to the plate body 310, are located above the light-transmitting through groove 3321, and cooperate with the light leakage prevention plate 336 to enable the side of the plate body 310 to be opposite to the light-transmitting through groove 3321. That is, as shown in fig. 3 and 5, the light leakage prevention plate 336 and the plate body limiting block 337 all extend out from the front side of the light shield 332, the light leakage prevention plate 336 is located at the lower side of the light transmission through groove 3321, the plate body limiting block 337 is located at the upper side of the light transmission through groove 3321, the plate body limiting block 337 and the light leakage prevention plate 336 form a "clip-shaped structure", and the "clip-shaped structure" clips the plate body 310 so that the side of the plate body 310 is opposite to the light transmission through groove 3321.

The lighting assembly 330 further includes a sealing plate 338, wherein the sealing plate 338 is disposed at an upper edge of the light shield 332, and extends from the light shield 332 to a top portion of a side close to the support portion of the plate body 310 for preventing light of the light source 335 from leaking out from the upper side of the plate body 310.

The two plate body limiting blocks 337 are matched with the light leakage prevention plate 336 to position the plate body 310, that is, as shown in fig. 3 and 5, the plate body limiting blocks 337 and the light leakage prevention plate 336 form a 'clip-shaped structure', so that the plate body 310 is positioned at the light transmission through groove 3321, and the light of the plate body 310 is uniform. The light leakage preventing plate 336 and the sealing plate 338 cooperate to prevent light of the light source 350 from leaking out above and below the plate body 310, thereby preventing the light source from being wasted and irritating the eyes.

The edge of the plate body 310 is lapped on the light leakage prevention plate 336 to be assembled with the light shield 332, and the light source 335 and the plate body 310 are arranged at the front side and the rear side of the light shield 332. This arrangement prevents the light source 335 from interfering with the assembly of the board 310 and the fixing member 320, and thus prevents the light source 310 from interfering with the fixing of the board 310. Another convenience is that the damage of the light source 335 caused by applying an external force to the light source 335 during the bearing process of the plate body 310 is also avoided.

In some embodiments, as shown in fig. 3 to 5, a mounting groove 3322 for mounting the light source is formed on a side of the light shield 332 opposite to the plate body 310; the light-transmitting through groove 3321 is opened from one end of the plate body 310 on the side close to the support portion to the other end of the plate body 310 on the side close to the support portion, that is, as shown in fig. 3 to 5, the light-transmitting through groove 3321 is opened from the right end to the left end of the plate body 310. The light source 335 has a bar shape and is disposed along a length direction of the mounting groove 3322, and a size of the light source 335 is adapted to a size of the light-transmitting through groove 3321. That is, the length and width of the light source 335, the length and width of the mounting groove 3322, and the length and width of the light-transmitting through groove 3321 are the same as, slightly smaller than, or slightly larger than the length or width of the rear side of the plate body 310, so that light covers the rear side of the plate body 310 and is irradiated from the rear side of the plate body 310 through the entire plate body 310 toward the front side of the plate body 310.

The mounting groove 3322 is used for accommodating the strip light source 335, the shape of the strip light source 335 is matched with the length and width of the light-transmitting through groove 3321, and the length and width of the light-transmitting through groove 3321 are matched with the side edge of the plate body 310 close to one side of the supporting part, so that the light source 335 covers the rear side surface of the plate body 310 through the light-transmitting through groove 3321, and the plate body 310 is uniformly illuminated.

In some embodiments, as shown in fig. 4, a light source positioning block 3323 is disposed in the mounting groove 3322, and the light source 335 has a light source positioning hole sleeved on the light source positioning block 3323 to position the light source 335 at the light-transmitting through groove 3321. A light source limiting block 3324 is arranged in the mounting groove 3322, the light source limiting block 3324 is arranged at the periphery of the light source 335, the light source limiting block 3324 is staggered with the light source positioning block 3323, and the light source positioning block 3323 is matched with the light source limiting block 3324 to prevent the light source 335 from rotating relative to the mounting groove 3322. The lighting assembly further includes a light source cover 339, wherein the light source cover 339 covers the opening of the mounting groove 3322 to prevent light of the light source 335 from leaking out of the opening of the mounting groove 3322.

A light source positioning block 3323 is disposed in the mounting groove 3322, and the light source positioning block 3323 is used for determining the mounting position of the light source 335, so as to precisely mount the light source 335. And light source stopper 3324 and light source locating piece 3323 are mutually wrong, prevent that light source 335 is rotatory relative to mounting groove 3322 to the light that makes light source 335 send leads to plate body 310 through printing opacity logical groove 3321 as far as possible, and this kind of mode avoids causing the energy waste, avoids the amazing eyes of light that spills.

As shown in fig. 3, the lighting assembly 300 has two conductive contacts 331, and when the rack 300 is installed in the refrigerator, the two conductive contacts 331 are respectively contacted with electrodes in the refrigerator to make the light source emit light. Therefore, as the rack 300 moves, the illumination assembly 330 also moves along with the rack 300 and can connect the electrodes from different positions, thereby solving the technical problem that the rack 300 has illumination blind areas. The conductive contacts 331 are connected to the light source 335 by wires that fit within the conductive contact receiving cavities 3331 (wires are not shown in the figures).

In some embodiments, as shown in fig. 3 and 4, the lighting assembly 330 further includes two conductive contact covers 333, the two conductive contact covers 333 respectively extend downward from two ends of the light shield 332, that is, from the left and right ends of the light shield 332, respectively, and respectively define a conductive contact accommodating cavity 3331 having an opening, and the two conductive contacts 331 are respectively assembled to the conductive contact accommodating cavity 3331.

It can be seen that the conductive contact cover 333 defines an open conductive contact receiving cavity 3331 for receiving the conductive contact 331 in the conductive contact receiving cavity 3331 to prevent accidental contact, and the open conductive contact receiving cavity 3331 facilitates removal and installation of the conductive contact 331.

The lighting assembly 330 has two conductive contacts 331 and two conductive contact covers 333, the two conductive contact covers 333 respectively extend downwards from two ends of the light shield 332, the conductive contact covers 333 and the conductive contacts 331 are located at two ends of the light shield 332, and the two conductive contacts 331 are sufficiently separated, so that the rack 300 is convenient to install and avoids internal short circuit.

The two conductive contact covers 333 extend downward from both ends of the light shield 332 to sufficiently separate the two conductive contacts 331, and this installation allows the two conductive contacts to be electrically connected to the positive and negative electrodes, respectively, with precision, thereby preventing short circuits, and allowing the rack 300 and the two support rails 200 to be installed relatively easily.

As shown in fig. 2, the light shield 332 is disposed at the rear side of the board body 310, and the board body 310 and the object carried on the board body 310 naturally apply downward and backward pressure to the light shield 333 and the conductive contact 331 under the action of gravity, that is, apply pressure to the light shield 333 and the conductive contact 331 toward the electrode, so as to ensure that the conductive contact 331 and the electrode are in good contact.

In some embodiments, as shown in fig. 3 and 5, an end of each conductive contact cover 333 away from the light shield 332 extends toward the support rail 200, i.e., a lower end of the conductive contact cover 333 extends toward the support rail 200 to form a protrusion 3332. The conductive contact 331 extends downward from the conductive contact cover 333 to a position of the projection 3332, extends toward the support rail 200 along the projection 3332, and has a distal end projecting from the projection 3332. It is apparent that the arrangement position of the projection 3332 described above is merely exemplary and not exclusive, and for example, the projection 3332 may be formed from the middle of the conductive contact cover 333.

It can be seen that the end of the conductive contact cover plate 333 remote from the light shield 332 extending toward the support rail 200 to form the projection 3332 will form the conductive contact receiving cavity 3331 into a vertical segment receiving cavity and a horizontal segment receiving cavity. Accordingly, the conductive contacts 331 will also form vertical segment conductive contacts and horizontal segment conductive contacts. The receiving cavity of the vertical section and the conductive contact of the vertical section may limit the conductive contact of the horizontal section from moving forward relative to the projection 3332 to prevent the conductive contact from contacting the electrode poorly during installation, or limit the conductive contact of the horizontal section from moving backward relative to the projection 3332 to cause the conductive contact 331 to protrude too far out of the projection 3332 to damage the electrode.

In some embodiments, as shown in fig. 3 and 5, the lighting assembly further includes two insulating fixing clips 334, and the two insulating fixing clips 334 are respectively clipped on the two conductive contact cover plates 333 to respectively limit the conductive contacts 331 from moving relative to the conductive contact accommodating cavities 3331. That is, one insulating retainer 334 is snap-fitted to the left conductive contact cover 333, and the other insulating retainer 334 is snap-fitted to the right conductive contact cover 333 (right side not shown). Optionally, each conductive contact cover 333 is provided with at least two clamping blocks 3333; the shape of each insulating fixing clip 334 is adapted to the shape of the conductive contact accommodating cavity 3331, for example, in this embodiment, the insulating fixing clip 334 is clipped at the junction of the vertical section accommodating cavity and the horizontal section accommodating cavity, then the shape of the insulating fixing clip 334 is also divided into the vertical section and the horizontal section, and the size of the insulating fixing clip 334 is slightly smaller than the size of the conductive contact accommodating cavity 3331, so that the insulating fixing clip 334 butts against the inner wall of the conductive contact accommodating cavity 3331. Each insulating fixing clip 334 is provided with a clip hole 3341 adapted to each clip block 3333, and the clip hole 3341 is sleeved on the clip block 3333 to clip the insulating fixing clip 334 on the conductive contact cover plate 333.

It can be seen that the insulating fixing clip 334 prevents the conductive contact 331 from moving relative to the projection 3332 to prevent the conductive contact 331 from making poor contact with the electrode during the mounting process.
