Detailed Description
The present invention first provides a light emitting device for a refrigerating and freezing apparatus. Fig. 1 is a schematic structural view of a light emitting device according to an embodiment of the present invention, and fig. 2 is a schematic structural sectional view of the light emitting device according to an embodiment of the present invention. Referring to fig. 1 and 2, a lighting device 20 for a refrigerating and freezing apparatus of the present invention includes a housing 21 and at least one light source 22. Fig. 3 is a schematic cross-sectional view of a housing according to one embodiment of the utility model.
The housing 21 has a plurality of side plates connected in sequence and enclosing a closed cylindrical structure and two end plates 216 respectively disposed at two opposite openings of the closed cylindrical structure to form a closed chamber 214 inside the housing 21.
The light source 22 is disposed in the closed chamber 214 of the housing 21 to emit light toward the inside of the closed chamber 214.
In particular, a part of the side plates is a light-transmitting plate 211 allowing light to pass through, and the other part of the side plates is a light-shielding plate 212 preventing light from passing through, so that the light emitted from the light source 22 is emitted through the light-transmitting plate 211, and the light-emitting device 20 emits light only toward the side where the light-transmitting plate 211 is located.
The light emitting device 20 for a refrigerating and freezing apparatus according to the present invention is provided with a light transmitting plate 211 for allowing light to pass through only a part of the plurality of side plates of the housing 21, and a light blocking plate 212 for strictly blocking light to pass through the other part of the plurality of side plates. Thus, the light emitted from the light source 22 in the housing 21 can only be emitted through the light-transmitting plate 211, and is not emitted from the light-shielding plate 212, that is, the light emitted from the light-emitting device 20 can only be irradiated to one side of the light-transmitting plate 211, so that the light-emitting direction of the light-emitting device 20 is restricted, and the light emitted from the light-emitting device is guided to a desired light-emitting position. It is understood that, when the light emitting device 20 emits light at different desired light emitting positions, the side where the light-transmitting plate 211 is located is different. That is, the desired light emitting direction of the light emitting device 20 can be adjusted by adjusting the orientation of the light transmissive plate 211 in the housing 21.
Meanwhile, the present application further provides an end plate at each of two end openings of the closed cylindrical structure of the housing 21, so that the closed chamber 214 can be formed in the housing 21. The lamp source 22 is disposed in the sealed chamber 214, and effectively isolates the inner space and the outer space of the sealed chamber 214, thereby preventing the external high-humidity airflow from entering the sealed chamber 214 to cause the generation of condensation.
In some embodiments, the housing 21 is an elongated, strip-shaped shell. The number of the light sources 22 is one, and the light sources 22 are strip-shaped light bars or strip-shaped light strips. Specifically, the light source 22 may include a plurality of light beads arranged in the form of a light bar or strip along the length of the housing 21.
In some embodiments, a limiting rib 23 for limiting the light source 22 is disposed in the sealed chamber 214 in the housing 21, the limiting rib 23 and a part of the side plate of the housing 21 enclose a light source accommodating cavity 213, and the light source 22 is plugged in the light source accommodating cavity 213.
It is understood that the limiting rib 23 divides the sealed chamber 214 into two parts, and the lamp source accommodating chamber 213 is one part of the sealed chamber 214. Due to the large space of the enclosed chamber 214, it is difficult to position the lamp source 22 therein. Therefore, the limiting rib 23 is arranged in the closed cavity 214, so that the lamp source accommodating cavity 213 with a small space is formed in the closed cavity 214, when the lamp source 22 is plugged in the lamp source accommodating cavity 213, the lamp source 22 can be limited through the limiting rib 23, the lamp source 22 can be assembled in the closed cavity 214 in a plugging mode, other extra fixing operations on the lamp source 22 can be omitted, and the lamp source 22 is effectively prevented from running out or shaking. That is, the positioning of the limiting rib 23 not only facilitates the installation of the lamp source 22, but also ensures the stability of the installation of the lamp source 22.
In some embodiments, the number of the limiting ribs 23 is two, and two limiting ribs 23 extend from two opposite side plates of the housing 21 towards the inside of the closed chamber 214. The extending ends of the two limiting ribs 23 are spaced by a preset distance to form a gap 215 on one side of the light source accommodating cavity 213, and the gap 215 is disposed opposite to the light-transmitting plate 211 to allow light emitted by the light source 22 in the light source accommodating cavity 213 to irradiate the light-transmitting plate 211 through the gap 215, so as to be emitted through the light-transmitting plate 211.
Specifically, the two limiting ribs 23 may extend from the light shielding plate 212 to the inside of the closed chamber 214, and the limiting ribs 23 may be integrally formed with the light shielding plate 212, and have the same material and the function of strictly shielding light. Thus, the light emitted from the light source 22 can exit the lamp housing chamber 213 only through the notch 215, and the light emitting direction of the light source 22 is restricted in advance. The light shielding plate 212 has a certain reflection effect on the light, enhancing the intensity of the light emitted from the notch 215 and the intensity of the light emitted from the light-transmitting plate 211.
Further, a light guide member may be disposed in another chamber of the closed chamber 214 partitioned by the limiting rib 23 to guide the light emitted from the notch 215 to the light-transmitting plate 211. Specifically, the light guide member may be a light guide pillar in the other chamber or a light guide film attached to an inner wall of the other chamber.
In some embodiments, the housing 21 is a temperature-sensing housing for sensing the temperature of the space where the housing is located and changing the color thereof with the temperature of the space where the housing is located, so that the light-emitting device 20 can emit light with different colors when the temperatures of the spaces where the housing is located are different. That is, when the temperature of the space where the housing 21 is located is different, the housing 21 can exhibit different color lighting effects. Therefore, the light emitting device 20 can automatically change the light emitting color according to the temperature change, on one hand, the user can intuitively know the temperature condition, the refrigeration condition and other information of the storage room through the color presented by the light emitting device 20, and on the other hand, the utility model does not need to design any control circuit for the light emitting device 20, thereby simplifying the circuit structure of the refrigerating and freezing device 1.
In addition, the light emitting device 20 of the present application senses temperature through the housing 21 and changes color with temperature, that is, the housing 21 instead of the light source 22 changes color with temperature, so that the light source 22 is not required to emit light with different colors, and the light source 22 only provides light. The different colors presented by the housing 21 are brighter or more translucent under the illumination of the light source 22, so that the light emitting device 20 presents the light emitting effect of the different colors. It can be seen that the present application reduces the requirements for the light source 22, reducing costs.
The utility model also provides a refrigerating and freezing device. Fig. 4 is a schematic structural view of a refrigerating and freezing apparatus according to an embodiment of the present invention. The refrigerator-freezer 1 of the utility model comprises a cabinet 10 and at least one lighting device 20 according to any of the embodiments described above.
At least one storage compartment is defined within the housing 10. Specifically, in the embodiment shown in fig. 4, a refrigerating compartment 11 and a freezing compartment 12 are defined in the cabinet 10, and the refrigerating compartment 11 is located above the freezing compartment 12. In other embodiments, only one storage compartment of the refrigerating compartment or the freezing compartment may be defined in the box body 10. In still other embodiments, the refrigerator body 10 may define other storage compartments, such as a temperature-changing compartment, in addition to the refrigerating compartment 11 and the freezing compartment 12.
The light emitting device 20 is disposed in one of the storage compartments. Specifically, in the embodiment shown in fig. 1, the light emitting device 20 may be disposed in the refrigerating compartment 11. In other embodiments, the light emitting device 20 may be disposed in other storage compartments with lighting requirements, increased atmosphere requirements, or other light requirements.
Specifically, the light emitting device 20 may be lit after the door of the storage compartment is opened. When a user opens the door body to take and place articles, the light-emitting device 20 interacts with the user through the color of the emitted light, and the user can see the color of the light emitted by the light-emitting device 20, so that the current state of the refrigerating and freezing device 1 can be known. For example, when the temperature in the storage compartment is low immediately after the refrigeration and freezing device 1 finishes refrigerating, the light-emitting device 20 may appear dark red; when the refrigeration of the refrigeration and freezing device 1 is finished for a long time, the temperature in the storage compartment rises more, and at this time, the light-emitting device 20 may show a gradually light pink color. Thus, the user can perceive the actual operating state of the refrigerating and freezing device 1 by the color presented by the light emitting device 20.
In some embodiments, an air duct cover plate 113 is arranged on the front side of the inner container rear wall 112 of the storage compartment, and a gap is formed between the two lateral sides of the air duct cover plate 113 and the inner container rear wall 112. The number of the light emitting devices 20 is two, and the two light emitting devices 20 are both disposed at the rear side of the duct cover 113 and are respectively located at two lateral side edges of the duct cover 113. That is to say, the light emitting device 20 is hidden behind the air duct cover plate 113, so that the user does not directly see the light emitting device 20 when using the refrigeration and freezing device 1, the phenomenon that light directly pierces eyes is avoided, and the comfort experience of the user is improved.
Further, the light-transmitting plate 211 of each light-emitting device 20 is disposed toward the gap on the side of the light-emitting device 20, so that the light emitted from the light-emitting device 20 is emitted from the gap, thereby improving the atmosphere decoration effect. That is, in these embodiments, the desired light-emitting position of the light-emitting device 20 is the gap between the air duct cover 113 and the inner container rear wall 112, and for this reason, the light-transmitting plate 211 of the light-emitting device 20 faces the gap, so that the light emitted by the light-emitting device 20 can be emitted only from the gap, and the internal structure of the refrigeration and freezing device can be prevented from being exposed to other positions or the use experience of the user can be prevented from being affected.
In some embodiments, an air outlet 111 for delivering airflow into the storage compartment is formed in a rear wall 112 of the inner container of the storage compartment, and the light-emitting device 20 is disposed adjacent to the air outlet. Therefore, the housing 21 of the light-emitting device 20 can sense the temperature at the air outlet 111 and change the color along with the temperature change at the air outlet 111, so that the light-emitting color of the whole light-emitting device 20 can accurately represent the air outlet temperature of the air outlet 111, and a user can visually know the air outlet temperature of the air outlet 111, the refrigeration state of the storage room and the like through the light-emitting color of the light-emitting device 20, thereby greatly improving the atmosphere effect and improving the use experience of the user.
In some embodiments, the number of the air outlets 111 is multiple, the multiple air outlets are arranged in two rows of air outlet groups spaced apart along the transverse direction, and each row of air outlet group includes multiple air outlets spaced apart along the vertical direction. The two light emitting devices 20 are respectively disposed adjacent to the two rows of air outlet groups, and each light emitting device 20 is a strip-shaped structure extending along the vertical direction.
Specifically, the length of the light emitting device 20 extending in the vertical direction may be equivalent to the height of each air outlet group distributed in the vertical direction, so that the temperature sensing shell 21 of the light emitting device 20 can uniformly sense the air outlet temperature of the air outlet 111 and present a uniform color.
In some embodiments, all of the light sources 22 of all of the light emitting devices 20 are arranged in parallel to ensure that the plurality of light sources 22 do not interfere with each other.
It will be appreciated by those skilled in the art that the refrigerator-freezer 1 of the present invention may be a refrigerator, freezer, or other device having a refrigerated or frozen storage function.
It should also be understood by those skilled in the art that the terms "upper", "lower", "front", "back", "top", "bottom", and the like used in the embodiments of the present invention are used with reference to the actual usage of the refrigeration and freezing apparatus 1, and these terms are only used for convenience of describing and understanding the technical solution of the present invention, and do not indicate or imply that the apparatus referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as limiting the present invention.
