Detailed Description

In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.

Fig. 1 to 6 show a preferred embodiment of the present invention.

The refrigerator lighting device 100 in the present embodiment includes a light emitting element 110 and a reflection portion 120, and the light emitting element 110 emits light for lighting, which may be any existing element capable of emitting lighting light, and specifically may be an LED lamp. The reflection part 120 has a reflection surface 121, and light emitted from the light emitting element 110 is irradiated to the reflection surface 121 and reflected into the freezing chamber 13 to illuminate the freezing chamber 13. That is, light emitting element 110 does not directly irradiate the illumination light to freezing chamber 13, but irradiates the light to reflecting surface 121 of reflecting portion 120, and then guides the light into freezing chamber 13 by reflection of reflecting surface 121, thereby illuminating freezing chamber 13.

Light emitting element 110 and reflecting portion 120 are both disposed at the bottom of door 11 of refrigerating compartment 12 of refrigerator 10, and refrigerating compartment 12 is located above freezing compartment 13. That is, refrigerator 10 in the present embodiment includes refrigerating room 12 and freezing room 13, freezing room 13 is located below refrigerating room 12, refrigerating room 12 includes door 11, and lighting device 100 is attached to the bottom of door 11 of refrigerating room 12 and illuminates freezing room 13.

The light emitting element 110 is arranged at the bottom of the door body 11 of the refrigerating chamber 12 above the freezing chamber 13, so that the assembly process of the light emitting element 110 is simpler, and when the light emitting element 110 is assembled or maintained, an operator does not need to bend down and stretch into the freezing chamber 13 for operation, and only the door body 11 of the refrigerating chamber 12 needs to be opened to install or maintain the light emitting element 110 more conveniently. Furthermore, the light is reflected into the freezing chamber 13 by the reflection part 120, so that the light can be effectively guided, and the structural arrangement of the light emitting element 110 is facilitated.

It should be noted that the above description of the light emitting element 110 emitting light to the reflecting surface 121 to emit illumination light into the freezing chamber 13 means that all illumination light emitted from the light emitting element 110 entering the freezing chamber 13 is reflected by the reflecting surface 121, the light emitting element 110 does not directly emit illumination light into the freezing chamber 13, and the light emitted from the light emitting element 110 is not easily directed to the eyes of the user due to the structural arrangement.

The lighting device 100 further includes a protective cover 130, the protective cover 130 has a reflective cavity 131 with an opening 132 facing downward, the reflective portion 120 is located in the reflective cavity 131, and after the light emitting element 110 emits light to the reflective surface 121 in the reflective cavity 131, the light reflected by the reflective surface 121 exits the reflective cavity 131 from the opening 132 and illuminates the freezing compartment 13. The protective cover 130 prevents the light emitted by the light emitting element 110 from overflowing and shining on other parts, thereby well preventing the light emitted by the light emitting element 110 from directly shining on the eyes of the user.

In order to prevent the protective cover 130 from interfering with other parts of the refrigerator 10, in the present embodiment, the protective cover 130 is completely embedded in the bottom of the door 11, and the opening 132 is flush with the bottom wall of the door 11 of the refrigerating chamber 12. Specifically, the light emitting element 110 may be positioned on the protection cover 130 and embedded in the door body 11 of the refrigeration compartment 12 along with the protection cover 130. In one embodiment, the light emitting element 110 can be located in the reflective cavity 131 and positioned on a wall of the reflective cavity 131. In another embodiment, an illumination hole may be formed on the wall of the reflective cavity 131, and the light emitted from the light emitting element 110 is irradiated onto the reflective surface 121 in the reflective cavity 131 through the illumination hole.

In particular, the reflection unit 120 may be a separate member having the reflection surface 121, or may be integrally formed with the protective cover 130 to be a part of the protective cover 130.

When the opening 132 of the protective cover 130 is exposed, foreign substances are easily dropped into the reflective chamber 131, and cool air of the freezing chamber 13 of the refrigerator 10 easily flows into the reflective chamber 131, so that the reflective surface 121 in the reflective chamber 131 condenses water mist, thereby affecting the reflective effect. Therefore, in order to improve the illumination effect of the illumination apparatus 100, in an embodiment, the illumination apparatus 100 further includes a light-transmitting plate 140, and the light-transmitting plate 140 is disposed at the opening 132 of the protection cover 130 and completely covers the opening 132 of the protection cover 130. The transparent plate 140 prevents foreign matters outside the lighting device 100 from entering the reflective cavity 131 and prevents water mist from being condensed on the reflective surface 121. And when the water mist is condensed on the light-transmitting plate 140, the cleaning is relatively convenient.

In order to make the light emitted from the light emitting element 110 more concentrated, in one embodiment, as shown in fig. 4, the reflecting surface 121 is curved and extends upward along the edge of the opening 132 of the protective cover 130 away from the freezing compartment 13 and is curved toward the freezing compartment 13. This makes it possible to concentrate the light beam emitted by the light emitting element 110 more on the one hand and to reflect the light beam into the freezer compartment 13 more easily on the other hand.

In one embodiment, in order to prevent the light beam emitted from the light emitting device 110 from directly irradiating the reflective cavity 131 to direct the light to the eyes of the user, as shown in fig. 4, the light emitting device 110 is inclined upward to emit light toward the reflective surface 121, so that the light emitted from the light emitting device 110 can be maximally reflected by the reflective surface 121 out of the opening 132 of the protective cover 130.

The lighting device 100 further includes a control switch for controlling the light emitting element 110 to be turned on or off, and the control switch is configured to control the light emitting element 110 to be turned on when the door of the freezing compartment 13 is opened and to control the light emitting element 110 to be turned off when the door of the freezing compartment 13 is closed.

As shown in fig. 7 to 9, the present invention also provides another preferred lighting device 300 for the refrigerator 10.

The lighting device 300 of the refrigerator 10 includes a light shield 310, a light-transmitting portion 320, and a light emitting element 350. The light shield 310 is opaque and may be made of a common opaque rubber, plastic or metal material. The transparent portion 320 is transparent and can be made of transparent material such as glass or crystal. The light shield 310 and the light-transmitting portion 320 together define an illumination chamber 360, and a light emitting element 350 for emitting light is disposed in the illumination chamber 360. A part of the light emitted from the light emitting device 350 is blocked by the light shielding cover 310, and a part of the light passes through the light transmitting portion 320 and is radiated to the outside.

The light-transmitting portion 320 includes a mounting portion 321, and the mounting portion 321 is configured to be mountable to a lateral edge of the rack 20 of the refrigerator 10 (a partition for delamination in the refrigerator 10), i.e., the light-transmitting portion 320 may be mounted on the rack 20 of the refrigerator 10 through the mounting portion 321. And in particular, to the exposed lateral edge of the rack 20 near the door of the refrigerator 10. Since the rack 20 of the refrigerator 10 is transparent, the light emitted from the light emitting device 350 is transmitted through the light transmitting portion 320 and then laterally irradiated into the rack 20, the light irradiated into the rack 20 is uniformly distributed at each position of the rack 20, and the rack 20 illuminates the upper and lower storage compartments of the rack 20. This kind of illumination mode can not make light penetrate user's eyes directly on the one hand, and on the other hand also makes the indoor light of distribution in the storing room of refrigerator 10 more even, can not appear shining the blind area because of the article of placing in the refrigerator 10.

In one embodiment, in order to make the light in the storage compartment of the refrigerator 10 more uniform, the outer surface of the light-transmitting portion 320 facing away from the illumination chamber 360 may be frosted. The outer surface of the transparent portion 320 refers to an exposed surface of the lighting device 300 when not mounted on the rack 20. In particular, in other embodiments, only the exposed surface of the light-transmitting portion 320 after being mounted on the rack 20 may be frosted, and the surface of the light-transmitting portion 320 contacting the rack 20 may be smooth, so as to facilitate the light to be incident into the rack 20.

The mounting portion 321 may be detachably connected to the rack 20 of the refrigerator 10, specifically, as shown in fig. 8, the mounting portion 321 may include a first clamping arm 3211 and a second clamping arm 3212, the first clamping arm 3211 and the second clamping arm 3212 are spaced apart from each other such that a gap for accommodating the rack 20 is formed between the first clamping arm 3211 and the second clamping arm 3212, and the lighting device 300 is configured to be mounted to the rack 20 by clamping the rack 20 in the gap between the first clamping arm 3211 and the second clamping arm 3212. The first and

second clip arms

3211 and 3212 not only enable the entire lighting device 300 to be mounted on the rack 20, but also enable light in the lighting chamber 360 to better extend into the storage chamber of the refrigerator 10 through the two, thereby improving the intensity of light in the storage chamber of the refrigerator 10.

In order to fix the lighting device 300 more stably, the first and second holding

arms

3211 and 3212 may be both elongated, and the first and second holding

arms

3211 and 3212 define an elongated gap. Specifically, the length of the gap between the first and second clamping

arms

3211 and 3212 may be equal to the width of the rack 20, i.e., the lighting device 300 may be distributed over the lateral edges of the rack 20. Further, the light shielding cover 310 and the light-transmitting portion 320 may be both elongated and define an illumination chamber 360 with an elongated through hole shape. In order to close both ends of the illumination chamber 360, both ends of the illumination chamber 360 in a length direction thereof may be provided with one end cap 330, respectively.

Further, the lighting device 300 further includes a power taking assembly 340 for providing power to the light emitting element 350, and the power taking assembly 340 includes a power taking wire 341 and a power taking plug, and the power taking plug can be inserted into an internal socket of the refrigerator 10 to take power to the inside of the refrigerator 10. The current-carrying lead 341 is connected to the light-emitting element 350 and extends out of the illumination chamber 360 through one of the end caps 330. After the lighting device 300 is installed on the rack 20 of the refrigerator 10, one end of the lighting device 300 may abut against the sidewall of the inner container of the refrigerator 10, that is, one of the end caps 330 of the lighting device 300 abuts against the sidewall of the inner container of the refrigerator 10, and the power-taking conducting wire 341 is led out from the end cap 330 abutting against the inner container of the refrigerator 10 and extends to the inside of the refrigerator 10 along the side edge of the rack 20 abutting against the inner container of the refrigerator 10 to take power. The wiring mode enables the position of the power-taking lead 341 to be quite hidden, the limb of a user is not easy to contact, and the risk of electric shock is avoided.

In one embodiment, the light shield 310 is disposed opposite to the mounting portion 321, so that the light beams in the lighting chamber 360 after the lighting device 300 is mounted on the rack 20 are all irradiated toward the direction close to the rack 20. After the lighting device 300 is installed, the light shield 310 is just disposed between the light source and the light emitting device 350, so that the light shield 310 can better prevent the light emitted by the light emitting device 350 from directly irradiating the eyes of the user, and the lighting effect is improved.

In order to emit the light emitted from the light emitting device 350 into the storage compartment of the refrigerator 10 completely, in one embodiment, the surface of the light shield 310 close to the light emitting device 350 may be a mirror surface capable of reflecting the light, so that the light emitted to the light shield 310 is reflected into the storage compartment of the refrigerator 10 in a reverse direction. In another embodiment, the light emitting device 350 is configured to emit light rays directed from the light shield 310 to the light-transmitting portion 320, that is, the light emitting device 350 emits beam-shaped light which does not emit light rays to the light shield 310, thereby effectively reducing the loss of the light rays by the light shield 310.

Further, the light emitting device 350 is configured to emit light parallel to the plane of the rack 20 when the lighting apparatus 300 is installed on the rack 20, so that the light emitted by the light emitting device 350 is directly emitted into the rack 20, thereby preventing the light from forming multiple reflections between the upper and lower surfaces of the rack 20 and causing loss of the light.

In order to more stably position the lighting device 300 on the rack 20, the gap between the first and second clamping

arms

3211 and 3212 may be as close as possible to the thickness of the rack 20 to which it is fitted, so as to prevent the lighting device 300 from shaking on the rack 20 after being mounted on the rack 20. However, when the gap between the first clamping arm 3211 and the second clamping arm 3212 is too close to the thickness of the rack 20, the rack 20 is difficult to be clamped into the gap between the first clamping arm 3211 and the second clamping arm 3212, which increases the difficulty in installing the lighting device 300.

To solve the above-mentioned drawbacks, in an embodiment, the first and

second clipping arms

3211 and 3212 may be made of a transparent flexible material (for example, the first and

second clipping arms

3211 and 3212 may be made of a transparent resin material), so that the first and

second clipping arms

3211 and 3212 can generate a small displacement toward or away from each other. One magnetic member is disposed in each of the first and second holding

arms

3211 and 3212, and the two magnetic members attract each other to cause the first and second holding

arms

3211 and 3212 to approach each other. When the first and second clamping

arms

3211 and 3212 clamp the rack 20, the first and second clamping

arms

3211 and 3212 are tightly attached to the rack, so that a large friction force is generated between the rack 20 and the first and second clamping

arms

3211 and 3212, and the problem of shaking of the lighting device 300 after being mounted on the rack 20 is effectively prevented.

As shown in fig. 10 to 11, the present invention also provides a refrigerator lighting device 400 in still another embodiment.

The lighting device 400 of the refrigerator 10 includes a protective cover 410, a light emitting element 420, a reflecting portion 450, and a refracting portion 430.

The protective cover 410 is opaque to light and defines an illumination chamber 440, and the light emitting element 420 is disposed within the illumination chamber 440. The protection cover 410 has an opening 441 for emitting light, and the light emitting device 420 in the illumination chamber 440 passes through the opening 441 of the protection cover 410 to illuminate the outside.

The reflection portion 450 is disposed in the illumination chamber 440 and has a reflection surface, and the reflection portion 450 can reflect the light emitted from the light emitting device 420 out of the opening 441 of the protection cover 410. In one embodiment, as shown in fig. 11, the reflecting portion 450 may have an arc shape and is configured to converge and reflect the light emitted from the light emitting element 420 toward the refracting portion 430.

The opening 441 of the protective cover 410 is provided with a refraction portion 430, and the refraction portion 430 closes the illumination chamber 440 into a sealed cavity. The refraction portion 430 is transparent, light passing through the opening 441 is refracted by the refraction portion 430 and then exits the illumination chamber 440, and the refraction portion 430 is configured to shift the light refracted by the refraction portion 430 toward the same direction. For example, when light guided out of the opening 441 of the protective cover 410 transversely penetrates into the refraction portion 430, the direction of the light refracted out of the refraction portion 430 will be shifted upward, downward, or in other directions.

It should be noted that, since the arrangement position of the lighting device 400 in the refrigerator 10 can be adjusted, the light emitted from the refraction portion 430 has the same effect regardless of the direction of the light. For example, when the light is shifted upward, the light becomes shifted downward by turning the lighting device 400 upside down.

In the lighting device 400 of the present embodiment, the light emitted from the lighting chamber 440 passes through the refraction portion 430 and then is deflected in the same direction, so that the light emitted from the lighting device 400 can be deflected downward after the lighting device 400 is disposed above the storage chamber of the refrigerator 10, thereby effectively preventing the illumination light from horizontally projecting into the eyes of the user. Although the light emitting direction of the light emitting elements 420 can be changed to prevent the light from directly irradiating the eyes in the prior art, the manner of changing the light emitting direction tends to limit the arrangement position of the light emitting elements 420. The present application prevents light from being directly radiated to the eyes of a user by using a manner of offsetting the light emitted from the light emitting element 420, so that the light emitting element 420 can be disposed at a suitable position regardless of the direction in which it emits light.

In order to provide a better integration of the external shape of the illumination device 400, in one embodiment, the wall of the refraction portion 430 facing away from the illumination chamber 440 may be planar. That is, the exposed wall surface of the refraction portion 430 is planar. In order to achieve the technical effect of deflecting the light passing through the refraction portion 430, the wall surface of the refraction portion 430 facing the illumination chamber 440 may be planar, and the wall surface of the refraction portion 430 facing the illumination chamber 440 is not parallel to the wall surface of the refraction portion 430 facing away from the illumination chamber 440, so that the light passing through the refraction portion 430 is deflected in the same direction.

In the above-mentioned embodiment of the refraction portion 430, when the wall surface of the refraction portion 430 facing the illumination chamber 440 is not parallel to the wall surface of the refraction portion 430 facing away from the illumination chamber 440 (for example, the refraction portion 430 may have a triangular prism shape), although the effect of deflecting the light rays can be better achieved, the thickness of the refraction portion 430 (the thickness from the direction pointing outside the illumination chamber 440 in the illumination chamber 440) will be larger in size. With reference to the direction of fig. 11, if the wall surface of the refraction portion 430 facing the illumination chamber 440 and the wall surface of the refraction portion 430 facing away from the illumination chamber 440 are both planar and non-parallel, in order to achieve the purpose of making the light beam shift downwards, the thickness of the downward part of the refraction portion 430 is larger, which increases the processing difficulty of the refraction portion 430, occupies more space, and is not easy to assemble.

In order to solve the above problem, in an embodiment, as shown in fig. 11, a wall surface of the refraction portion 430 close to the illumination chamber 440 includes a plurality of inclined wall surfaces 431, each inclined wall surface 431 is not parallel to a wall surface of the refraction portion 430 away from the illumination chamber 440, and each inclined wall surface 431 is configured to deflect the light penetrating through each inclined wall surface 431 in the same direction after being refracted out of the refraction portion 430. That is, the wall surface of the refraction portion 430 facing the illumination chamber 440 is divided into a plurality of small wall surfaces each of which is not parallel to the wall surface of the refraction portion 430 facing away from the illumination chamber 440, so that the light can be deflected without increasing the thickness of the refraction portion 430.

The inclined walls 431 of the refraction portion 430 facing the illumination chamber 440 may be parallel to each other or not, but the inclined walls 431 are inclined in the same direction for the purpose of shifting the light rays in the same direction. Further, each of the inclined wall surfaces 431 may have a long shape, and both ends of each of the inclined wall surfaces 431 extend to both ends of the wall surface of the refraction portion 430 near the illumination chamber 440 along the length direction of the inclined wall surface 431. For ease of manufacture, the areas of the sloped walls 431 may all be the same.

The lighting device 400 in the above embodiment may be disposed at the top of the storage chamber of the refrigerator 10, the reflective portion 450 is configured to transmit the light reflected by the reflective portion to the refractive portion 430 in a transverse direction, and the refractive portion 430 is configured to deflect the light refracted by the refractive portion in a downward direction. This prevents the light refracted in the refracting part 430 from being incident laterally into the eyes of the user, causing discomfort to the user.

As shown in fig. 6, a second aspect of the present invention also provides a refrigerator 10, where the refrigerator 10 includes the lighting device 100 in any one of the above embodiments. Further, the refrigerating chamber 12 of the refrigerator 10 has two door bodies 11 with two doors, bottom walls of the two door bodies 11 are arranged in parallel, and the bottom walls of the two door bodies 11 are both provided with the light emitting element 110 and the reflection portion 120.

Thus, it should be appreciated by those skilled in the art that while a number of exemplary embodiments of the invention have been illustrated and described in detail herein, many other variations or modifications consistent with the principles of the invention may be directly determined or derived from the disclosure of the present invention without departing from the spirit and scope of the invention.
