Detailed Description
Fig. 1 is a schematic structural view of a refrigerator according to one embodiment of the present invention; fig. 2 is a schematic structural view of a door body 100 according to an embodiment of the present invention; fig. 3 is a partially schematic structural view of a door body according to an embodiment of the present invention, which is cut in a longitudinal direction. Specifically, the present embodiment provides a door 100 for a refrigerator 200. Generally, as shown in fig. 1, a refrigerator 200 includes a cabinet 201 and a compartment 202, and a door 100 is rotatably mounted on the cabinet 201 to open or close the compartment 202. As shown in fig. 3, the door body 100 of the present embodiment may include an outer panel 110 and an inner panel 120. Wherein the inner plate 120 is disposed inside the outer plate 110. Specifically, the inner panel 120 is a structure in which the door body 100 is close to the outside, and the inner panel 120 is a structure in which the door body 100 is closer to the compartment 202, and the inner panel 120 is configured such that the color of the inner wall 121 and/or the outer wall 122 thereof changes in accordance with a change in the temperature of the compartment 202, so as to determine the temperature of the compartment 202 from the color of the inner wall 121 and/or the outer wall 122 of the inner panel 120.
As far as now, the temperature in the compartment 202 is directly detected and displayed inside or outside the door 100 of the refrigerator 200. Since additional temperature detection requires additional sensors and additional power supplies and wires for providing power to the sensors and the display device, there is a certain requirement for the wiring structure inside the door 100 of the refrigerator 200, and more power is also consumed. In this embodiment, since the color of the inner wall 121 and/or the outer wall 122 of the inner plate 120 changes directly according to the temperature of the compartment 202, a user can visually know the temperature of the compartment 202 by observing the color of the inner plate 120, and does not need a sensor, a power supply, an electric wire and a display device, and the interior of the door body 100 does not need a wiring structure, so that the door body has a simple structure, is more convenient and faster for detecting the temperature of the compartment, and is more energy-saving.
In this embodiment, the inner wall 121 of the inner plate 120 is the side wall near the compartment 202, and the outer wall 122 of the inner plate 120 is the side wall near the outer plate 110. Whether the inner wall 121 or the outer wall is relatively close to the compartment 202 and therefore at a temperature comparable to that of the compartment 202. And the temperature difference between the inner wall 121 and the outer wall 122 is not so large that the temperature difference can be ignored. Therefore, the present embodiment can determine the temperature of the compartment 202 by observing the color of the inner wall 121 and/or the outer wall 122 of the inner plate 120.
Since the outer wall 122 of the inner panel 120 is close to the outside, in order to facilitate viewing the color of the outer wall 122 of the inner panel 120, in one specific embodiment, the outer panel 110 of the present application may be a transparent material. During use, a user can directly see the color of the outer wall 122 of the inner plate 120 from the outside of the door body 100 of the refrigerator 200 through the transparent outer plate 110, thereby determining the temperature in the compartment 202. As one embodiment, the material of the inner plate 120 of this embodiment is LBA-resistant ABS or LBA-resistant PS, where LBA is trans-1-chloro-3, 3, 3-trifluoropropene, ABS is a terpolymer of acrylonitrile, butadiene, and styrene, and PS is polystyrene. And the material of the outer wall 122 may be tempered glass.
FIG. 4 is a cross-sectional view of an inner panel of the door body according to one embodiment of the present invention. As a specific embodiment of the present invention, as shown in fig. 4, the inner panel 120 of the present embodiment may further include an inner panel body 123 and a heat sensitive material coating 124. Wherein the thermosensitive material coating 124 is formed at an inner wall and/or an outer wall of the inner plate body 123. As one of the embodiments, the thermosensitive material coating 124 is formed only at the inner wall of the inner panel body 123, and the user of the embodiment can obtain the temperature of the compartment 202 only by opening the door body 100 to observe the color of the thermosensitive material coating 124 at the inner wall of the inner panel body 123 of the door body 100. In another embodiment, if the heat sensitive material coating 124 is formed only at the outer wall of the inner panel body 123, the outer panel 110 of the door body 100 must be a transparent material. At this time, the user can directly obtain the temperature of the compartment 202 by observing the color of the thermosensitive material coating 124 at the inner wall of the inner plate body 123 through the transparent outer plate 110 outside the refrigerator 200. In another embodiment, the inner wall and the outer wall of the inner plate body 123 are both provided with the heat-sensitive material coating 124, so that a user can observe the color of the heat-sensitive material coating 124 at the inner wall of the inner plate 120 body through the transparent outer plate 110 to obtain the temperature of the compartment 202, and can observe the color of the heat-sensitive material coating 124 at the inner wall of the inner plate 120 of the door body 100 by opening the door body 100 to obtain the temperature of the compartment 202. In the practical application process, the design can be carried out according to the requirements.
As a specific embodiment of the present invention, the inner plate 120 includes at least two different types of thermosensitive material coatings 124, and the at least two thermosensitive material coatings 124 are juxtaposed on an inner wall or an outer wall of the inner plate body 123. Each heat sensitive material coating 124 exhibits a different color at a different temperature.
FIG. 5 is a schematic view of a vertical arrangement of heat sensitive material coatings according to one embodiment of the present invention;
FIG. 6 is a schematic view of a lateral arrangement of a coating of thermally sensitive material according to another embodiment of the present invention; fig. 7 is a schematic view of a ring-like arrangement of heat sensitive material coatings according to yet another embodiment of the present invention. Specifically, in this embodiment, the thermosensitive material coating 124 may be designed to be disposed side by side left and right (as shown in fig. 5), or may be designed to be disposed side by side up and down (as shown in fig. 6), or may be designed to be annular from inside to outside (as shown in fig. 7). As other embodiments, the thermal sensitive material coating 124 may be designed in other different shapes or patterns. However, no matter what shape the thermosensitive material coatings 124 are finally formed, thermosensitive material coatings 124 displaying different colors cannot be overlapped and are arranged side by side, so that the situation that the colors are not clearly recognized due to different colors displayed by different thermosensitive material coatings 124 is avoided.
As a specific embodiment of the present invention, since the thermosensitive material coating 124 shows different colors at different temperatures, the user can obtain the temperature values according to the colors of the different thermosensitive material coatings 124 during use. Preferably, each thermal sensitive material coating 124 exhibits a color in one temperature range and a transparency in the other temperature range. Or each thermosensitive material coating 124 is formed by combining multiple thermosensitive materials, and different colors are cooperatively displayed among multiple different thermosensitive material coatings 124 at different temperatures, so that a user can more intuitively know the temperature corresponding to each color, and the temperature of the compartment 202 is obtained. Preferably, the thermosensitive material coating 124 of the present embodiment includes at least three or more colors, and the displayed color is also at least three or more colors.
FIG. 8 is a cross-sectional view of an inner panel of a door body according to another embodiment of the present invention. As a specific embodiment of the present invention, as shown in fig. 8, the inner panel 120 may further include a transparent material layer 125. The transparent material layer 125 is formed outside the thermosensitive material coating 124, and the material of the transparent material layer 125 is selected to be a corrosion-resistant material. Since the thermosensitive material coating 124 is generally easily corroded or scratched by the external environment when exposed for a long time, the color change is not sensitive or the color is not clearly displayed after a long time. This embodiment therefore provides a layer of corrosion resistant material outside the heat sensitive material coating 124. In particular, the material must also be transparent to facilitate viewing of the color of the heat sensitive material coating 124.
As another specific example of the present embodiment, the material of the inner plate 120 in the present embodiment may include a heat-sensitive material. In other words, the heat sensitive material may be directly incorporated into the inner panel 120 during the molding of the inner panel 120, so that the color of the inner panel 120 may be directly changed according to the change of the external temperature, thereby enabling the temperature of the compartment 202 to be obtained. In the present embodiment, the heat-sensitive material in the inner plate 120 may be a mixture of a plurality of heat-sensitive materials. And the plurality of heat-sensitive materials may allow the inner panel 120 to display different colors at different temperatures.
Specifically, whether the inner wall and/or the outer wall of the inner plate body 123 is provided with the heat-sensitive material coating 124 or the material of the inner plate 120 is close to the heat-sensitive material, the inner plate 120 of the door body 100 of the refrigerator 200 is directly communicated with the compartment 202 and is mainly used for observing the temperature of the compartment 202 of the refrigerator 200, and the temperature of the compartment 202 of the refrigerator 200 is generally between-5 ℃ and 15 ℃. Therefore, the temperature discoloration range of the thermosensitive material coating 124 or the inner plate 120 with the thermosensitive material is preferably between-5 ℃ and 15 ℃, and one color is changed every 1 ℃ to 5 ℃, so that the user can more intuitively and clearly know the approximate temperature of the compartment 202. The temperature variation range and the color displayed along with the temperature variation can be designed according to the actual requirement.
Fig. 9 is a schematic structural view of an inner panel of a door body, a molecular sieve, and a light source according to an embodiment of the present invention. As a specific embodiment of the present invention, as shown in fig. 9, the door body 100 of the present embodiment may further include a light source 130, the light source 130 may be disposed at one side of the inner panel 120, and light emitted from the light source 130 irradiates the inner panel 120, so as to observe the color of the inner panel 120. Specifically, the light source 130 may be disposed on a side of the inner and outer panels adjacent to the compartment 202 or adjacent to the outer panel 110. In practical use, the light source 130 is preferably disposed at a side of the inner plate 120 close to the outer plate 110. The light source 130 may be normally turned on or may be turned on when the door 100 is opened.
As a specific embodiment of the present invention, as shown in fig. 9, the door body 100 of the present embodiment may further include a molecular sieve 140. The molecular sieve 140 of the present embodiment is constructed in a frame-type structure, both sides of which are connected to the inner plate 120 and the outer plate 110, respectively.
Specifically, the primary function of molecular sieve 140 is to absorb moisture. Because the gap between the inner plate 120 and the outer plate 110 of the door body 100 is closed, when the temperature of the inside and outside environment of the door body 100 is inconsistent, fog is easily formed and condensed at the space and the side wall position between the inner plate 120 and the outer plate 110, which not only affects the beauty of the refrigerator 200, but also affects the condition that a user observes the color of the inner plate 120 from the appearance. Therefore, in the present embodiment, the molecular sieve 140 is formed in a frame-type structure, so that a closed space is formed between the inner plate 120 and the outer plate 110 of the molecular sieve 140 when both sides of the molecular sieve 140 are connected to the inner plate 120 and the outer plate 110, respectively. The enclosed space can be filled with inert gas to further reduce the generation of fog.
FIG. 10 is a schematic view taken along section line A-A in FIG. 9; as a specific embodiment of the present invention, as shown in fig. 9 and 10, the top ends of the molecular sieves 140 are located lower than the top ends of the inner plates 120. The light source 130 is a light bar and is located above the inner plate 120. At this time, the light source 130 can irradiate only the inner plate 120 at a position above the molecular sieve 140. The user can obtain the temperature of the compartment 202 by observing the color of the inner plate 120 at a position above the molecular sieve 140. At this time, if the inner panel 120 is composed of the inner panel 120 body and a plurality of thermosensitive material coatings 124 juxtaposed, the thermosensitive material coatings 124 are preferably arranged vertically right and left at positions above the inner panel 120 so as to be irradiated by the light source 130.
FIG. 11 is a schematic block diagram of the inner panel of the door body, molecular sieves, and light sources according to another embodiment of the utility model; fig. 12 is a schematic view taken along section line B-B in fig. 11.
As one specific example of the present invention, as shown in fig. 11 and 12, a frame-shaped space is defined between the outer edges of the molecular sieves 140 and the outer edges of the inner plate 120. The light source 130 includes a plurality of light source units, which are enclosed together in a frame-shaped structure and located at the outer periphery of the molecular sieve 140.
Specifically, since the molecular sieves 140 are opaque, when the light source 130 is disposed at the outer periphery of the molecular sieves 140, the light source 130 can irradiate only a position of the inner plate 120 located outside the molecular sieves 140, that is, a frame-type spatial position defined between the outer edges of the molecular sieves 140 and the outer edges of the inner plate 120. At this time, if the inner plate 120 is formed of the inner plate 120 body and the thermosensitive material coating 124, the thermosensitive material coating 124 is preferably disposed at a portion of the inner plate 120 located outside the outer position of the molecular sieve 140. And may be provided with a plurality of heat sensitive material coatings 124 juxtaposed on each side. Different coatings 124 of thermally sensitive material may also be applied around each edge, each edge being formed in a different color to represent a different temperature range.
As a specific embodiment of the present invention, as shown in fig. 3, the door body of the present embodiment may further include a frame 150, a connector 160, and a decoration strip 170. The frame 150 is disposed around the inner plate 120 and the outer plate 110. The connector 160 is disposed inside the frame 150. The molding 170 is connected to the frame 150 by a connector 160. Specifically, the light source 130 may be disposed on the connection member 160 at an inner position of the connection member 160.
Fig. 13 is a schematic structural view of a door body according to another embodiment of the present invention. As a specific embodiment of the present invention, this embodiment further provides a refrigerator 200, and the refrigerator 200 may include a cabinet 201 and an upper door 100. Specifically, the refrigerator 200 of the present embodiment further includes a second door body 180, and the door body 100 is a small door on the second door body 180. Specifically, the refrigerator 200 has a through hole 181 at a middle position of the second door body 180, the door body 100 is disposed at the position of the through hole 181 of the second door body 180, and the door body 100 is rotatably connected to the second door body 180.
