Detailed Description
Fig. 1 is a schematic configuration diagram of a refrigeration and freezing apparatus according to an embodiment of the present invention. The refrigerating and freezing apparatus 1 of the present invention includes a box 10 and at least one light emitting device 20.
At least one storage compartment is defined within the housing 10. Specifically, in the embodiment shown in fig. 1, 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.
Fig. 2 is a schematic structural view of a light emitting device according to an embodiment of the present invention. In particular, the light emitting device 20 of the present invention includes a temperature sensing housing 21 for sensing a temperature of a space where the light emitting device 20 is located and changing a color according to a temperature change of the space where the light emitting device is located, and at least one light source 22 for emitting light toward the inside of the temperature sensing housing 21 so that the light emitting device 20 exhibits different color light emitting effects when the temperatures of the spaces where the temperature sensing housing 21 is located are different.
That is, the refrigerating and freezing device 1 of the present invention is designed to have the light emitting device 20 specifically including the temperature sensing housing 21 and at least one light source 22 for emitting light toward the inside of the temperature sensing housing 21, and the light emitting device 20 can exhibit different color light emitting effects when the temperature of the space in which the temperature sensing housing 21 is located is different. That is to say, 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 compartment 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, and simplifies the circuit structure of the refrigeration and freezing device 1.
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 addition, the light emitting device 20 of the present application senses the temperature through the temperature sensing housing 21 and changes color with the temperature change, that is, the temperature sensing housing 21 instead of the light source 22 changes color with the temperature change, so the light source 22 is not required to emit light with different colors, and the light source 22 only provides light. The different colors displayed on the temperature sensing housing 21 are brighter or more transparent under the irradiation of the light source 22, so that the light emitting device 20 can display the light emitting effect of different colors. It can be seen that the present application reduces the requirements for the light source 22, reducing costs.
In some embodiments, the light source 22 may be a white light lamp that emits only monochromatic light. The white light lamp is simple and easy to obtain, and has low price, thereby effectively reducing the cost of the refrigeration and freezing device 1. Specifically, the light source 22 may include a plurality of lamp beads arranged in parallel.
In alternative embodiments, the light source 22 may be other light sources capable of emitting a single color of light or light sources capable of emitting a color change of light.
Further, all the light sources 22 of all the light emitting devices 20 are arranged in parallel to ensure that the plurality of light sources 22 do not affect each other.

In other embodiments, the inside or outside of the temperature sensitive casing 21 may be provided with a temperature sensitive color changing layer made of a temperature sensitive color changing ink. That is, a part of the temperature sensitive housing 21 may change color with a change in temperature. In either case, the purpose of changing the color of the temperature sensitive casing 21 according to the change in temperature can be achieved.
In some embodiments, an air outlet 111 for delivering airflow into the storage compartment is formed in a wall of the inner container defining the storage compartment, and the light-emitting device 20 is disposed adjacent to the air outlet 111. Therefore, the temperature-sensitive shell 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.
Furthermore, the inner container wall of the storage compartment comprises an inner container rear wall 112 at the rear side of the storage compartment, and the air outlet 111 is formed in the inner container rear wall 112. Accordingly, the light emitting device 20 is disposed adjacent the liner rear wall 112.
In some embodiments, the number of the air outlets 111 is multiple, the air outlets 111 are arranged in two rows of air outlet groups spaced apart along the transverse direction, and each row of air outlet group includes the air outlets 111 spaced apart along the vertical direction, so as to uniformly supply air into the storage compartment.
Further, the number of the light emitting devices 20 may be two, two light emitting devices 20 are respectively disposed adjacent to two rows of the 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, a duct cover 113 is disposed on the front side of the inner container rear wall 112, and a gap is formed between the lateral sides of the duct cover 113 and the inner container rear wall 112. The two light-emitting devices 20 are disposed at the rear side of the duct cover 113 and at two lateral side edges of the duct cover 113, respectively, so that light emitted by the two light-emitting devices 20 is emitted from a gap between the duct cover 113 and the liner rear wall 112.
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. Meanwhile, the light emitting device 20 is located at the lateral side edge of the air duct cover plate 113, so that light emitted by the light emitting device 20 can be directly emitted from the gap between the air duct cover plate 113 and the inner container rear wall 112, and the atmosphere decoration effect is improved.
In some alternative embodiments, the light emitting device 20 may also be disposed at other positions adjacent to the air outlet 111.
In some embodiments, the temperature sensing housing 21 of the light emitting device 20 is a bar-shaped cylindrical structure extending in the vertical direction. That is, the upper end portion and the lower end portion of the temperature sensing case 21 are both formed with openings, and the inside of the temperature sensing case 21 is hollow.
Further, the number of the light sources 22 is two, and the two light sources 22 are respectively provided at the upper end portion and the lower end portion of the temperature sensing housing 21. That is, the light emitting device 20 is a bar-shaped light emitting device that lights at both ends. The lamp source 22 is provided at an end of the temperature sensing housing 21 to facilitate mounting of the lamp source 22.
In some embodiments, a light guide 23 is provided in the temperature sensing housing 21 to guide the light emitted from the two light sources 22 at the two ends of the temperature sensing housing 21 to the middle inside the temperature sensing housing 21 through the light guide 23. Therefore, the condition that the brightness of the temperature sensing shell 21 gradually weakens from two ends to the middle can be avoided, the brightness uniformity of the light-emitting device 20 is improved, and the decorative effect of the light-emitting device 20 is improved.
Further, in some embodiments, the light guide 23 may be a light guide rod within the temperature sensitive housing 21. In other embodiments, the light guide member may be a light guide film attached to the inner wall of the temperature sensing housing 21.
Fig. 3 is a schematic cross-sectional view of a light emitting device according to one embodiment of the present invention. In some embodiments, the temperature sensing housing 21 has a plurality of side plates connected in sequence and enclosing a closed cylindrical structure, and the two light sources 22 are respectively disposed at two opposite end openings of the closed cylindrical structure. Some of the side plates are light-transmitting plates 211 allowing light to pass through, and the other side plates are light-shielding plates 212 preventing light from passing through, so that the light emitted from the light source 22 is emitted through the light-transmitting plates 211, and the light-emitting device 20 emits light only toward the side where the light-transmitting plates 211 are located.
In the present invention, only a part of the plurality of side plates of the temperature sensitive casing 21 is provided as the light transmitting plate 211 which allows light to pass therethrough, and the other part of the plurality of side plates is provided as the light blocking plate 212 which strictly blocks light from passing therethrough. Accordingly, the light emitted from the light source 22 in the temperature sensitive housing 21 can be emitted only 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 be emitted only to the 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-transmitting plate 211 in the temperature sensitive housing 21.
