[0034] Refer to Figure 1, which shows a schematic diagram of the use of a household appliance 20 in an embodiment of the present application. The shell assembly 10 provided in an embodiment of the present application is arranged on the corresponding structure of the household appliance 20 and is used to make color changes according to external operations.

[0035] The household appliance 20 referred to in this application is mainly an appliance for performing specific functions, not limited to household or commercial use, and the specific functions may be, for example, washing, processing, and storing items. The household appliance 20 may be a refrigeration appliance, as shown in FIG1 , for example, the household appliance 20 is a refrigerator.

[0036] The household appliance 20 may have a housing, a storage space for storing items (not shown), a master control unit (not shown), and a door body 21 for opening and closing the storage space. The door body 21 has a connection structure (not shown) for sealing the storage space, a panel structure facing the user 30, and a door body that carries the connection structure and the panel structure. The following description is based on an example in which the housing assembly 10 is disposed in the door body 21, and the housing assembly 10 is at least partially disposed in the door body or the panel structure.

[0037] The panel structure has a visible layer, and the visible layer can make the housing assembly 10 display a color change to show it to the user 30. As needed, at least part of the visible layer is a transparent structure, a hollow structure, a frosted structure, or a combination thereof. An outer layer is provided outside the visible layer, so that the outer layer is arranged as the outermost layer of the panel structure in a direction away from the accommodation space. The visible layer can be protected by the outer layer from external damage caused by external impact or other external factors.

[0038] Referring to FIGS. 2 to 6 , the housing assembly 10 includes an emitting layer 200, a color-changing layer 300, and a sensing layer 100. The emitting layer 200 is provided with an emitting unit 210, and the emitting unit 210 is used to send a corresponding color-changing signal m according to a preset signal p. The color-changing layer 300 is provided in the visible layer of the household appliance 20, and the color-changing layer 300 can change its own color according to the corresponding color-changing signal m. The sensing layer 100 is provided with a sensing element 101, which is used to sense an external trigger signal q and generate a preset signal p according to the trigger signal q, as shown in FIG. 5 .

[0039] The above-mentioned shell assembly 10 and the household appliance 20 having the shell assembly 10 can change the color of the color-changing layer 300 by emitting a preset signal p. The color change can be controlled by simply controlling the emitting part 210. The control is convenient, and the color-changing layer 300 and the emitting layer 200 are more flexibly arranged, without affecting the integrity of the appearance of the household appliance 10, and the color change effect is changeable.

[0040] The color-changing layer 300 generates corresponding colors according to the triggering of the color-changing signal m. This color change can be achieved by changing its own color or by changing the properties of certain materials so that the desired color is displayed.

[0041] In one embodiment, the color-changing layer 300 is at least partially made of a photochromic material or a thermochromic material, and changes the color displayed by itself according to the color change signal m required by different materials, so as to change the overall color of the color-changing layer 300. Specifically, the photochromic material may include organic photochromic compounds (spiropyran, fulgide, diarylethenes, azobenzenes), inorganic photochromic compounds (WO3, MoO3, TiO2, calcium iodide and mercuric iodide mixed crystals, copper chloride, pot chloride, silver chloride) and rare earth complexes, etc. Specifically, the thermochromic material may include spiropyran, fluorescent derivatives, polythiophene, liquid crystal materials, vanadium dioxide, etc.

[0042] In another embodiment, the color-changing layer 300 is at least partially made of photosensitive denaturing material or thermosensitive denaturing material, and changes its own physical properties according to the color-changing signal m required by different materials, such as changing the transmittance to different colors of light (or different wavelengths). At this time, a matching light-emitting element is provided in the emitting layer 200. When the color-changing layer 300 receives the color-changing signal m to change its properties, after the light emitted by the light-emitting element reaches the color-changing layer 300, only light of the required color is allowed to pass through, thereby realizing a change in the color displayed by the color-changing layer 300.

[0043] In one embodiment, when the color-changing layer 300 is at least partially made of a photosensitive material, the emitting unit 210 can emit light of different wavelengths and / or different intensities as different color-changing signals m. When the color-changing layer 300 is at least partially made of a thermosensitive material, the emitting unit 210 can generate temperatures of different values ​​as different color-changing signals m.

[0044] It can be understood that the "at least part" in "the color-changing layer 300 is at least partly made of photosensitive color-changing material or thermosensitive color-changing material" herein does not specifically refer to the component ratio of the color-changing layer 300. "At least part" means that a certain layer or a certain position in the color-changing layer 300 is provided with a whole piece of photosensitive material or thermosensitive material, so that at least part of the structure of the color-changing layer 300 can change color.

[0045] Specifically, the emission unit 210 matches the characteristic setting of the color-changing layer 300, each color-changing layer 300 corresponds to at least one matching emission unit 210, one color-changing layer 300 can match multiple emission units 210, and multiple emission units 210 match different areas of the same color-changing layer 300. The emission units 210 can form an emission group, and multiple emission groups constitute an emission array, and each emission group or emission array can be uniformly encoded.

[0046] It can be understood that the color-changing signal m emitted by each transmitting unit 210 can cover a preset area of ​​the color-changing layer 300. Under the premise of ensuring the color-changing effect, the intervals of the transmitting units 210 are installed according to the preset area and the arrangement of the color-changing layer 300. The size of the preset area is related to factors such as the power of the transmitting unit 210, the distance from the color-changing layer 300, and the characteristics of the color-changing signal emitted by the transmitting unit 210.

[0047] After the transmitter 210 obtains the preset signal p, it sends a corresponding color-changing signal m to the color-changing layer 300 according to the indication of the preset signal p, so that the color-changing layer 300 changes color. A processor and a converter may be provided in the transmitter 210, the processor is used to preset the corresponding relationship between different preset signals p and the color-changing signal m, and the converter is used to convert the preset signal p.

[0048] In one embodiment, the color-changing layer 300 includes at least two, and each color-changing layer 300 can produce different colors to match a variety of color-changing signals m, produce a variety of effects, and improve user experience.

[0049] Specifically, each color-changing layer 300 of different colors can be arranged at different positions of the same layer of the door body 21, or at different layers of the door body 21 in a direction away from the accommodation space. When at least two color-changing layers 300 are respectively arranged at different positions of the same layer of the door body 21, the different color-changing layers 300 can be arranged according to a preset pattern, or can cover the entire visible layer of the door body 21.

[0050] Specifically, the color-changing layer 300 of the same color can also display different patterns, colors of different brightness or different saturation. In other embodiments where only one color-changing layer 300 is provided, the one color-changing layer 300 can also present multiple display states according to different color-changing signals m.

[0051] In one embodiment, the color-changing layer 300 includes at least two regions capable of displaying different colors, each region matching one or more emission parts 210, or the same color-changing layer 300 is made of different materials, so that different regions of the same color-changing layer 300 display different colors.

[0052] In one embodiment, the housing assembly 10 further includes a substrate 220, the emitting unit 210 is disposed on the substrate 220, and the substrate 220 and the emitting unit 210 constitute an emitting layer 200. The substrate 220 is installed in the door body or the panel structure, that is, the emitting layer 200 as a whole can be disposed in the door body or the panel structure.

[0053] Furthermore, in the direction of the door body 21 away from the accommodation space, the color-changing layer 300 is arranged on the outside of the emission layer 200. Since the color-changing layer 300 is arranged on the visible layer or the color-changing layer 300 is arranged close to the visible layer, the emission layer 200 is arranged away from the visible layer to avoid affecting the display effect. The color-changing layer 300 and the emission layer 200 can be arranged at a preset distance. When the color-changing signal m emitted by the emission layer 200 has a certain transmission distance and penetration, a sensing layer 100 or other door body 21 structures can be arranged between the color-changing layer 300 and the emission layer 200.

[0054] The substrate 220 may be a supporting structure for supporting the transmitting unit 210. In other embodiments, the substrate 220 may be a structure in the door body 21. The substrate 220 may be provided with circuits or connected with other elements to form a circuit board for connecting other components of the housing assembly 10.

[0055] In one embodiment, referring to FIG. 2, FIG. 2 shows a schematic cross-sectional structure diagram of a housing assembly 10 in an embodiment of the present application, and the sensing layer 100 is disposed between the color-changing layer 300 and the emission layer 200, so that in the direction of the door body 21 away from the accommodation space, the color-changing layer 300 is located at the outermost portion of the housing assembly 10, and the display effect is better. In order to ensure the color-changing effect, the color-changing layer 300 has a preset thickness, and the sensing element 101 of the sensing layer 100 should be configured to at least sense the trigger signal q outside the preset thickness. When the sensing layer 100 is located between the color-changing layer 300 and the emission layer 200, preferably, the sensing layer 100 and the color-changing layer 300 are arranged synchronously, and the area overlap rate of the sensing layer 100 and the emission layer 200 with the color-changing layer 300 is at least 80%. Combined with the structure of the three-layer overlapping arrangement, the color-changing layer 300 can display accordingly in real time according to the external trigger signal q. In particular, when the trigger signal q is a gesture of the user 30, the color change of the color-changing layer 300 has a better effect of following the gesture, and can change color according to the user operation and interact with the user, thereby producing a better interactive experience.

[0056] In one of the embodiments, refer to FIG. 3, which shows a schematic cross-sectional structure diagram of the housing assembly 10 in another embodiment of the present application. In the direction of the door body 21 away from the accommodating space, the sensing layer 100 can be located outside the color-changing layer 300. At this time, the color-changing layer 300 is located between the sensing layer 100 and the emission layer 200. The sensing layer 100 can be made of the same material as the visible layer. The area overlap rate of the sensing layer 100 and the emission layer 200 with the color-changing layer 300 is at least 80%, which does not affect the display effect. The color-changing layer 300 can also display in real time according to the external trigger signal q. In particular, when the trigger signal q is a gesture of the user 30, the color change of the color-changing layer 300 has a better effect on following the gesture, resulting in a better interactive experience. At the same time, it is particularly suitable for the case where the sensing distance of the sensing element 101 is limited.

[0057] In one embodiment, the sensing layer 100 can be located at other positions of the housing assembly 10, as long as it can receive the trigger signal q and transmit the preset signal p to the transmitting unit 210. Specifically, the sensing layer 100 can be located at different positions of the same layer as the color-changing layer 300 or the transmitting layer 200; the sensing layer 100 can also be arranged at intervals from the color-changing layer 300 or the transmitting layer 200, and transmit signals through communication lines or wireless communications. For example, the sensing layer 100 is separated from the color-changing layer 300 or the transmitting layer 200 by other structures, or the sensing layer 100 and the color-changing layer 300 or the transmitting layer 200 are separated by a preset distance.

[0058] In one embodiment, the shell component 10 itself may not include the sensing layer 100, and the shell component 10 can obtain the preset signal p emitted by the external operating unit 40. The operating unit 40 is also provided with a sensing element 401, and the operating unit 40 is equivalent to the sensing layer 100 of the shell component 10. The sensing element 401 is used to sense the external trigger signal q and generate a preset signal p according to the trigger signal q, and then transmit the preset signal p to the transmitting unit 210, such as transmitting the signal through a communication line or wireless communication. As a preferred embodiment, the household appliance 20 has a control panel that can be operated by the user 30, and the control panel is the above-mentioned operating unit 40, and the shell component 10 can obtain the preset signal p output from the control panel to achieve color change. As another preferred embodiment, refer to Figure 4 The external operating unit 40 is a mobile device 50, such as a mobile phone or a tablet, which controls the housing assembly 10 of the door body 21 of the networked household appliance 20 to produce a corresponding color change display through application software and intelligent interconnection. The sensing element 401 is an electronic component in the mobile device 50.

[0059] The sensing element 101, 401 can be located between the color-changing layer 300 and the emission layer 200, or outside the color-changing layer 300, or at other locations. The trigger signal q is formed according to the trigger action. The sensing element 101, 401 can directly contact the user 30 to form the trigger signal q, or obtain the trigger action of the user 30 in the air, or there are multiple sensing elements 101, 401, and each sensing element 101, 401 obtains a corresponding trigger signal q. It can be understood that the trigger action matches the sensing principle of the sensing element 101, 401, and the trigger action can include sound, light, gesture, pressing a button, etc. Correspondingly, the sensing element 101, 401 can include a sound sensor, a light sensor, a camera, a physical button, and a touch button, etc.

[0060] Furthermore, through a certain conversion algorithm, the trigger signal q is converted into a specific preset signal p, and the transmitter 210 receives the specific preset signal p and transmits a corresponding color change signal m, so that the color change pattern and effect of the color change layer 300 can correspond to the trigger action one by one, and achieve a real-time display effect, or the color change pattern and effect of the color change layer 300 can form an interactive effect with the trigger action. The conversion algorithm can be set according to demand to make the display pattern and effect more diversified.

[0061] In one embodiment, the sensing element 101, 401 includes a touch portion, which is used to sense an external trigger signal q or a combination of trigger signals q, the combination of trigger signals q includes at least two different trigger signals q, and each trigger signal q or the combination of trigger signals q corresponds to at least one color displayed by the color layer 300.

[0062] Specifically, the touch control unit can sense at least one trigger signal q or a combination of trigger signals q. Different trigger signals q match the manner in which the touch control unit obtains the trigger signal q, and controls the transmitting unit 210 to generate a corresponding color change signal m.

[0063] The touch control unit can directly contact the user 30 to form a trigger signal q. The trigger action is the position touched by the user 30 or the movement track of the user 30. Different positions or different tracks can constitute different trigger signals q. The touch control unit can obtain the trigger action of the user 30 in the air to form a trigger signal q. The trigger action is the state of the user 30's body part, such as gesture action, voice command or body movement. The touch control unit is provided with a corresponding type of sensor to sense the above trigger action. Different gesture actions, voice commands or body movement methods constitute different trigger signals q.

[0064] In one embodiment, the sensing element 101, 401 includes a pressure portion, which is used to sense a trigger signal q or a combination of trigger signals q caused by an external action, the combination of trigger signals q including at least two different trigger signals q, and each trigger signal q or the combination of trigger signals q corresponds to at least one color displayed by the color layer 300.

[0065] The pressure part can directly contact the user 30 to form a trigger signal q, and the triggering action is that the user 30 presses different positions of the pressure part, presses different pressure parts, or feels different pressures on the pressure part, forming different trigger signals q. For example, the pressure part can be a button group arranged on the housing assembly 10, and the button group can sense and obtain the pressure applied by the user 30 on the pressure part, so that the closed loop of the components of the button group generates a preset signal p.

[0066] In one embodiment, the household appliance 20 further includes a controller 400, and the sensing elements 101, 401 and the transmitting unit 210 are connected to the controller 400 respectively. The controller 400 is used to control the transmitting unit 210 to generate a corresponding color change signal m according to the trigger signal q. The controller 400 includes a processing module, a conversion module, a storage module and a communication module. Referring to FIG6, FIG6 shows a control logic diagram of the controller 400 of an embodiment of the present application. The controller 400 synchronously receives the trigger signal q obtained by the sensing elements 101, 401, and the processing module analyzes the trigger signal q or the combination of the trigger signal q and splits it. The conversion module converts the trigger signal q into a preset signal p that can be recognized by the transmitting unit 210 and transmits it to the transmitting unit 210. The transmitting unit 210 itself converts the preset signal p into heat or light energy and transmits it to the color change layer 300. The storage module is preset with a corresponding conversion algorithm, and the storage module can also store the processing process. The communication module is responsible for the communication inside or outside the processor. The controller 400 may be provided in the household appliance 20 itself, or the controller 400 may be provided as an independent matching housing assembly 10 in the household appliance 20. Furthermore, the controller 400 may also include the above-mentioned control panel.

[0067] Furthermore, in some embodiments, the household appliance 20 further includes a circuit board, which is a substrate 220, and the circuit board and the transmitter 210 provided together form a transmitter layer 200, or the circuit board is independently provided. The controller 400 is provided on the circuit board, and the sensing element 101, 401 and the transmitter 210 are connected through a line. In other embodiments, the controller 400 can be provided away from the household appliance 20, and the controller 400 is wirelessly connected to the sensing element 101, 401 or the transmitter 210 by means of remote communication. It can be understood that the type of wireless connection is not limited, and at least data is exchanged between the controller 400 and the household appliance 20 by means of the connection.

[0068] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0069] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application.
