Detailed Description

The technical solutions of the present application are described clearly and completely by the following specific examples, and it is obvious that the described examples are some, but not all, of the examples of the present application. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments in the present application without making any creative effort belong to the protection scope of the present application.

One embodiment of the present invention provides a refrigeration appliance, such as a refrigerator, wine chest, beverage chest, or the like. The refrigeration appliance comprises a door body 1, the door body 1 being used for opening and closing a storage compartment (not shown in the figures) of the refrigeration appliance.

As shown in fig. 1, the door body 1 includes an inner door 20 and an outer door 10, the inner door 20 has a receiving cavity 30 for storing articles, and the outer door 10 can be used for opening and closing the receiving cavity 30.

The inner door 20 is also provided with a lighting assembly 8, and light of the lighting assembly 8 can be irradiated into the accommodating cavity 30 from the rear part of the accommodating cavity 30 to provide lighting rays for the accommodating cavity 30.

So set up, hold chamber 30 and be located between luminescent light source and the user, shine the dead angle little, and light is difficult for sheltering from. In use, the user can more easily see objects placed in the receiving cavity 30 with the direct-lit assembly.

Illustratively, the light assembly 8 is electrically connected to the electrical circuit of the refrigeration appliance, and the electrical power is provided by the electrical circuit of the refrigeration appliance to provide illumination to the receiving cavity 30. The power for the lighting assembly 8 may also be provided by a separate power source or an external power source.

As shown in fig. 1, the inner door 20 is connected to the refrigerator body, and the outer door 10 is hinged to the edge of the inner door 20. The inner door 20 can open and close the storage compartment in a reversible manner, and the outer door can open and close the receiving chamber 30 in a reversible manner. In fact, the connection manner between the inner door 20 and the main body of the refrigeration appliance, and between the outer door 10 and the inner door 20 may be replaced with other forms, as long as the outer door 10 can open and close the receiving chamber 30, and the inner door 20 can open and close the storage chamber, to achieve the object of the embodiment of the present invention. For example, instead of the connection between the inner door 20 and the main body of the refrigeration appliance and/or the outer door 10 and the inner door 20 being in a sliding rail and chute manner, the outer door 10 or the inner door 20 opens and closes the accommodation chamber 30 or the storage compartment in a translational manner.

In one or more possible embodiments, the outer door has a transparent region, and a user can see the condition in the accommodating cavity from the transparent region without opening the outer door. In the past scheme, the light in the accommodating cavity is insufficient, and the condition in the accommodating cavity can be clearly seen only by opening the outer door. The embodiment of the application has good illumination capability, and a user can see the inner condition of the accommodating cavity from the transparent area on the outer door. It will be appreciated that this may be achieved by providing the outer door or a localised region on the outer door as a transparent material, which may be, for example, toughened glass or an organic resin material or the like.

It will be appreciated that there is at least a partial intersection of the transparent area with the area of the orthographic projection of the receiving chamber on the outer door, and that the user can see the inside of the receiving chamber from a front or horizontal perspective.

Referring to fig. 3-7, in one or more possible embodiments, the lighting assembly 8 includes a light-transmissive cover 89 that allows light to pass through, and the light-transmissive cover 89 may be part or all of the rear wall 31 of the receiving cavity 30. Exemplarily, one or several areas of the light-transmissive cover 89 are provided on the rear wall 31, for example, the light-transmissive cover 89 is embedded in a partial area of the rear wall 31; or the light-transmissive cover plate 89 serves as the rear wall 31 of the accommodation chamber 30, and the light of the illumination assembly 8 enters the accommodation chamber 30 through the light-transmissive cover plate 89.

So set up, lighting assembly 8 is integrated at holding chamber 30 back wall 31, is difficult for the mistake to touch lighting assembly 8 when holding in the chamber 30 and put article, and lighting assembly 8 does not occupy the space that holds chamber 30. Especially, when the rear wall 31 of the accommodating chamber 30 is entirely formed by the light-transmitting cover plate 89, the illumination light distribution is more uniform and the irradiation range is larger.

Illustratively, the light-transmissive cover 89 is accessible via the receiving cavity 30. It will be appreciated that no other means need be provided in front of the light-transmissive cover 89, on the one hand, further freeing up space for the receiving cavity 30; on the other hand, no other device is used for shielding, so that the lighting effect is better; in three aspects, the light-transmitting cover plate 89 can be wiped inside the accommodating chamber 30, and cleaning is facilitated.

Referring to fig. 6-7, in one or more possible embodiments, the inner door 20 has a sliding track 321 thereon, and the lighting assembly 8 is inserted into the inner door 20 through the sliding track 321.

The sliding rail 321 on the inner door 20 is replaced by a sliding groove or a sliding groove is additionally added, and accordingly, the lighting assembly is adaptively changed, and the purpose of the present embodiment can still be achieved. The lighting assembly 8 is inserted into the inner door 20 through a sliding groove and/or a sliding rail structure, so that the installation structure is simple and the operation is easy; especially, when the area of the lighting assembly 8 is large, the stress at the joint of the lighting assembly 8 and the inner door 20 is more uniform, no local gap is caused due to uneven stress, and the possibility that foreign matters or wet and cold air enter the lighting assembly 8 is reduced.

It will be appreciated that in order to insert the light assembly 8 into the inner door 20, the light assembly 8 should also have an adaptive structure that is compatible with the sliding grooves and/or the sliding tracks on the inner door 20. In one or more possible implementations, the adapting structure includes a slide slot that receives a slide rail on the inner door 20 and/or a slide rail that inserts into a slide slot on the inner door 20.

Referring to fig. 7, the receiving cavity 30 includes a side wall 32, a protruding sliding rail 321 is provided on the side wall 32, a groove-shaped sliding slot 82 is provided on a side of the lighting assembly 8, and the sliding rail 321 is inserted into the sliding slot 82. It is understood that the sliding groove 82 and the sliding rail 321 are disposed on the side wall 32 and the side of the lighting assembly 8, respectively, to achieve the object of the present embodiment.

With continued reference to fig. 7, the receiving cavity 30 further includes a back plate 33 connected to the side wall 32. In one or more embodiments not shown in the drawings, one of the slide rail and the slide groove may be provided on the front surface of the back plate 33, the other of the slide rail and the slide groove may be provided on the back surface of the lighting assembly 8, and the slide rail may be inserted into the slide groove, which may also achieve the object of the embodiments of the present invention.

Referring to fig. 8, in one or more possible embodiments, the light assembly 8 includes a housing 81 and a light transmissive cover 89, the light transmissive cover 89 being positioned in front of the housing 81.

The housing has a third flange 814 folded forward, and a cavity is formed between the transparent cover 89 and the third flange 814, and at least a portion of the light guide plate 85 is located in the cavity.

The housing 81 has groove-like sliding grooves 82 on both sides.

The side of the housing 81 has a front protrusion 811 and a rear protrusion 812 spaced apart from each other and extending toward the side, and the sliding groove 82 includes a gap 812 between the front protrusion 811 and the rear protrusion. With reference to fig. 7, the slide groove 82 on the light assembly 8 includes this gap.

Referring to fig. 7, the sidewall 32 of the receiving chamber 30 has a protrusion 322 protruding from the sidewall 32, and the protrusion 322 is spaced apart from the sliding rail 321 on the sidewall 32 and has a second gap 323. The light-transmitting cover 89 and the front protrusion 311 on the housing 81 are located in the second gap 323. The protrusion 322 can limit the lighting assembly 8 to prevent the light-transmitting cover 89 from falling forward.

On the other hand, the second gap 323 can be regarded as a sliding groove on the sidewall 32, and the light-transmitting cover 89 and the front protrusion 811 together form a sliding rail on the lighting assembly 8. The second gap 323 can play a certain role in clamping the light-transmitting cover 89 and the front protrusion 811, and prevent the light-transmitting cover 89 from being separated from the housing 81.

With continued reference to fig. 7, in one or more possible implementations, a protrusion 322 on the sidewall 32 extends into the receiving cavity 30, the protrusion 322 covering at least a portion of a side edge of the lighting assembly 8 in front of the lighting assembly 8. The protrusion 322 may protect the lighting assembly 8 to reduce the possibility that fine debris or cold and humid air in the accommodating cavity 30 may enter the lighting assembly 8 from the junction between the lighting assembly 8 and the sidewall 32.

Referring to fig. 2-4, in one or more possible implementations, there is also an air inlet channel 40 and an air outlet channel 50 in communication with the receiving cavity 30.

The air intake passage 40 is located at the top of the accommodating chamber 30.

As shown in fig. 4, the air intake passage 40 includes an air deflector 41. The lower end of the air deflector 41 extends to the front of the lighting assembly 8 and covers at least part of the upper edge of the lighting assembly 8, i.e. the air deflector 41 covers at least part of the upper edge of the lighting assembly from the front of the lighting assembly 8. In this way, the possibility that wind entering the accommodating cavity 30 along the wind deflector 41 enters the lighting assembly 8 from the top of the lighting assembly 8 is reduced.

In one or more possible implementations, the air deflection plates 41 are inclined from top to bottom to back. The cold air entering the accommodating cavity 30 is guided to the lighting assembly 8 and flows downwards along the lighting assembly 8, so that more accommodating space can be covered, and the cooling efficiency is higher.

In one or more possible implementations, the air deflection panel 41 includes a first flange 412 extending rearward; the first flange 412 covers at least part of the top surface of the lighting assembly 8. With this arrangement, it is possible to reduce the possibility of the residue or the cold and humid air in the air inlet duct 40 entering the lighting module 8 from the top of the lighting module 8.

Referring to FIG. 5, in one or more possible implementations, the back plate 33 includes a second flange 331 extending forward from the bottom; the lower end of the lighting assembly 8 abuts against the second flange 331. The lower end of the lighting assembly 8 is prevented from contacting the bottommost portion of the accommodating cavity 30, and the possibility that water accumulated at the bottom of the accommodating cavity 30 enters the lighting assembly 8 from the bottom is reduced.

In one or more possible implementations, the first flange 412, the back panel 33, the second flange 331 and the side wall 32 together define a cavity in which the lighting assembly 8 is disposed. The cavity may reduce the likelihood of foreign objects or cold, humid air entering the lighting assembly 8, reducing the probability of damage to the lighting assembly 8.

In one or more possible implementations, the lower end of the lighting assembly 8 abuts the second turned-up edge 331; the lower end of the back plate 33 is spaced from the bottom of the accommodating chamber 30. The lower end of the lighting assembly 8 is arranged at an interval with the bottom of the accommodating cavity 30, so that the possibility that accumulated water at the bottom of the accommodating cavity 30 enters the lighting assembly 8 from the bottom is reduced.

Referring to fig. 4, in one or more possible implementations, the air inlet channel 40 is located at the top of the accommodating chamber 30, and the air outlet channel 50 is located at the bottom of the accommodating chamber 40. The cold air for refrigeration enters the accommodating cavity 30 from the upper part, flows downwards, flows out from the air outlet channel at the bottom, can flow to more areas in the accommodating cavity 30, and is higher in refrigeration efficiency.

In one or more possible implementations, the lighting assembly 8 includes a light emitting unit 80, and a distance from the air inlet channel 40 to the light emitting unit 80 is greater than a distance from the air outlet channel 50 to the light emitting unit 80, that is, the light emitting unit is closer to the air outlet channel. In fact, the temperature at the air inlet channel 40 is slightly higher than the temperature at the air outlet channel 50, and the light emitting unit 80 generates a certain amount of heat during operation, so that the temperature rises, the temperature difference greatly aggravates the possibility of condensation generated near the light emitting unit 80, and therefore the light emitting unit 80 is arranged near the air outlet channel 50, and the possibility of condensation can be reduced due to the small temperature difference.

Referring to fig. 5, in one or more possible implementations, the lighting assembly 8 includes a light guide plate 85 and a light emitting unit 80. The light emitting unit 80 is located at the lower end of the lighting assembly 8, and the lower end of the light guide plate 85 abuts against the light emitting unit 80. The generated bright light of the light emitting unit 80 is diffused in the light guide plate 85, the light guide plate 85 exhibits light emitting and brightening effects, and the light guide plate 85 and the light emitting unit 80 together constitute the light emitting assembly 91.

In one or more possible implementations, a cavity for accommodating the light emitting assembly 91 is formed between the housing 81 and the light-transmissive cover 89, the light emitting unit 80 is placed at the bottom of the cavity, and the lower end of the light guide plate 85 abuts against the light emitting unit 80.

In one or more possible implementations, the housing 81 has a recess 813 extending rearward, and a portion of the light emitting unit 80 is located in the recess 813.

In one or more possible implementations, the accommodating cavity 30 is divided into two or more storage spaces distributed up and down by the transverse partition and/or the storage device 38. The lighting assembly 8 can provide light for all or most of the storage spaces, and therefore the upper end of the lighting assembly 8 extends to the storage space at the uppermost end, and the lower end of the lighting assembly extends to the storage space at the lowermost end.

It will be appreciated that the transverse partition and/or the storage device 38 may be fixed in the receiving cavity or may be removably connected to the receiving cavity. For example, the storage device 38 is hung or clamped in the accommodating cavity 30, and storage spaces are respectively formed above and/or below the storage device 38; the storage device 38 can be restored to a large storage space after being removed from the storage cavity.

Since the storage device 38 and/or the storage space may have a position and a size, users are used to store objects with different sizes according to different storage devices 38 and/or storage spaces, that is, the placement positions of large-sized objects and small-sized objects are often variable, and users have to use a lot of effort to arrange the accommodating cavity 30 in order to conveniently find the objects. The embodiment of the application provides a new lighting scheme, the accommodating cavity is positioned between the lighting device and the user, and the irradiation dead angle is smaller, so that the user can easily see the condition in the accommodating cavity 30 under the condition of not frequently tidying the accommodating cavity 30.

In one or more possible implementations, the lighting assembly 8 extends from an upper end of the receiving cavity 30 to a lower end of the receiving cavity 30. With such an arrangement, the illumination assembly 8 can provide illumination light for all or most of the area of the accommodating cavity 30 in the form of a surface light source, and the illumination dead angle is less; especially in the case where the receiving chamber 30 is located between the illumination assembly 8 and the user and the illumination light is not easily blocked, a wider range of illumination can be achieved without using the illumination assembly 8 having a high brightness.

In one or more possible implementations, the inner door 20 has a through hole penetrating the front and rear of the inner door 20 and a cover 37, the cover 37 is mounted on the inner door 20 along the through hole, and the cover 37 defines the receiving cavity 30 for placing an object. The cover 37 has a forwardly facing open end from which objects in the receiving cavity 30 can be accessed.

Illustratively, the side walls of the cover 37 also constitute the side walls 32 of the receiving cavity 30.

The cover 37 also has, illustratively, a plate closing the rear end, which constitutes the back plate 33 of the housing chamber 30.

With the inner door 20 and the accommodating cavity 30, the lighting assembly 8 is easy to install, and the lighting assembly 8 can be installed in the cover 37 firstly in the manufacturing process, and then the cover 37 is installed on the inner door 20; particularly advantageous for the implementation of various solutions for embodiments in which the lighting assembly 8 has a large area.

Please refer to fig. 8:

illustratively, the lighting assembly 8 may include a light-transmissive cover plate 89, a light guide plate 85, a light emitting unit 80 and a housing 81, wherein the light guide plate 85 is located between the light-transmissive cover plate 89 and the housing 81, and the light emitting unit 80 is located at a side of the light guide plate 85. The side of the housing 81 is provided with a groove-like sliding groove 82.

The housing 81 is used to mount the lighting assembly 8 to the refrigeration appliance and may provide some support for other components of the lighting assembly 8.

Light generated by the illumination assembly 8 can enter the receiving cavity 30 through the light-transmissive cover 89 to provide illumination light to at least a portion of the receiving cavity 30. In one or more possible implementations, a certain color, such as black, may be provided, so that the perspective may be reduced, the lighting assembly 8 is not operated, and the user may see the internal structure of the lighting assembly 8, and the visual effect is better.

The light guide plate 85 and the light emitting unit 80 constitute a light emitting module 91. The light generated by the light emitting unit 80 can be diffused in the light guide plate 85, so that the light guide plate 85 has a light emitting and shining effect as a whole, and the shining light of the light guide plate 85 enters the accommodating cavity 30 through the cover plate. Due to the arrangement, on the one hand, the light is softer and cannot be too dazzling; in the second aspect, the brightness is more uniform, and the conditions of local over-brightness and local over-darkness are reduced; in the third aspect, the locally generated light is guided to a larger area by the light guide plate 85, which not only reduces the number and cost of the light emitting units 80, but also saves the installation space and the production efficiency of the light emitting units 80.

In a possible implementation manner, the light guide plate 85 and the light emitting unit 80 can also be implemented by other forms of light emitting components 91, such as a LED strip between the light-transmissive cover 89 and the housing 81.

Illustratively, the lighting assembly 8 may further include a diffuser plate 87 positioned between the light guide plate 85 and the light transmissive cover plate 89. The diffuser 87 diffuses 87 the transmitted light to make the light that eventually enters the receiving cavity 30 more uniform and soft.

Illustratively, the lighting assembly 8 may further include a reflective layer 83 between the light guide plate 85 and the housing 81. The reflecting layer 83 can reflect light irradiated on the reflecting layer 83, so that the light enters the accommodating cavity 30 through the light-transmitting cover plate 89, the lighting efficiency is improved, and the energy waste is reduced.

Illustratively, the lighting assembly 8 may also include a barrier coating on the front or back side of the light transmissive cover panel 89. The light throughput can be reduced by the barrier coating, and the regions with and without the barrier coating can show different light and shade differences when the lighting assembly 8 is in operation. The personalized shielding coating is arranged to form a certain pattern, so that the aesthetic feeling of the refrigeration appliance is improved. The shielding coating is arranged on the rear side of the light-transmitting cover plate 89, so that the probability of being scratched can be reduced, and the shielding coating is more durable.

Illustratively, the light-transmitting cover 89 is hermetically connected with the edge of the housing 81 to reduce the probability of moisture entering the inside of the lighting assembly 8, the lighting assembly 8 is not easily damaged, and water drops are not easily generated on the light-transmitting cover 89, so that the lighting effect is better.

The light emitting unit 80 is used for emitting light, and may be obtained by connecting a plurality of light beads or LED tubes in series or in parallel, or may be a single light bead or tube. It is understood that the light emitting unit may be other common light emitting elements or be formed by assembling existing light emitting elements, such as fluorescent lamps, light emitting diodes, etc., and the object of the present embodiment can still be achieved.
