Referring to fig. 2 and 3, fig. 2 is a schematic diagram illustrating a positional relationship among the door 20, the electrochromic layer 30 and the glass panel 90 in the refrigerator 1 according to an embodiment of the present invention, and fig. 3 is a schematic block diagram of the refrigerator 1 according to an embodiment of the present invention.
In some embodiments, the refrigerator 1 may further include an electrochromic layer 30, a storage unit 50, a control unit 60, and one or more detection units 40. The electrochromic layer 30 is disposed on an outer side of the door body 20 and configured to exhibit different colors according to a change in voltage applied thereto. The one or more detection units 40 are used for detecting the state of the storage compartment 14 and outputting state information. The memory cell 50 is used to store correspondence of state information to a voltage of the electrochromic layer 30.
The input terminal of the control unit 60 is electrically connected to the detection unit 40, the output terminal of the control unit 60 is electrically connected to the electrochromic layer 30, and the control unit 60 is further configured to receive the status information and adjust the voltage applied to the electrochromic layer 30 according to the correspondence stored in the storage unit 50, so that the color of the electrochromic layer 30 changes with the temperature of the storage compartment 14.
The electrochromic layer 30 is disposed at an outer side of the door body 20 by coating or the like with an electrochromic material. The electrochromic material is a material which can generate stable and reversible chemical reaction under the action of an external electric field and generate color change.
Referring to fig. 4, fig. 4 is a structural view of an electrochromic layer 30 in a refrigerator 1 according to an embodiment of the present invention. In some embodiments, the electrochromic layer 30 may be formed from a tunable power source E, a color changing layer 34 (tungsten trioxide, WO) 3 ) An ion conducting layer 36, an ion storage layer 38, and two transparent electrodes 31, 32 (e.g., indium tin oxide, ITO). The two transparent electrodes 31 and 32 are disposed opposite to each other and located at the outermost layer, the color-changing layer 34, the ion conducting layer 36, and the ion storage layer 38 are disposed between the two transparent electrodes 31 and 32 and sequentially disposed from one transparent electrode 31 to the other transparent electrode 32, and two poles of the adjustable power source E are respectively loaded on the two transparent electrodes 31 and 32.
When the color-changing layer works, the adjustable power supply E loads a certain voltage between the two transparent electrodes 31 and 32, and the color-changing layer 34 generates oxidation-reduction reaction under the catalysis of the voltage, so that the color of the color-changing layer is changed. The ion conducting layer 36 is made of a special conductive material (such as lithium perchlorate solution, etc.), and the ion storage layer 38 stores corresponding counter ions during the oxidation-reduction reaction of the color-changing layer 34, so as to keep the charge balance of the whole system. The ion storage layer 38 may be provided as an electrochromic material having a color shifting property opposite to that of the color shifting layer 34, and thus may function as a color superposition or complementation, for example, the color shifting layer 34 may be formed of an anodic oxidation color shifting material, and the ion storage layer 38 may be formed of a cathodic reduction color shifting material.
Further, since the oxidation-reduction reaction of the color-changing layer 34 is related to the catalysis of the voltage, the change of the voltage may change the reaction degree of the color-changing layer 34, thereby showing that different colors are presented under different voltages.
One or more detection units 40 may be provided. The detection unit 40 is used to detect various states of the storage compartment 14 of the refrigerator 1, such as temperature, humidity, etc., and output temperature state information, humidity state information, etc.
The storage unit 50 may be a Read Only Memory (ROM), an erasable and editable read only memory (EPROM or flash memory), or the like. Before the refrigerator 1 leaves the factory, a specific color-changing layer 34 may be tested to obtain a relationship between voltage and color, and then the state information, the voltage and the color of the storage compartment 14 are associated to form a corresponding relationship, for example, when the temperature of the storage compartment 14 is-9 ℃, it is preset that the color corresponding to the temperature is green, and the voltage corresponding to the green is 2V.
The control unit 60 may be a processor (chip IC, etc.) having an input electrically connected to the detection unit 40 for receiving the state information of the detection unit 40, and an output electrically connected to the electrochromic layer 30 for adjusting the voltage applied to the electrochromic layer 30 according to the correspondence stored in the storage unit 50. In some specific embodiments, the output of the control unit 60 is electrically connected to the adjustable power supply E of the electrochromic layer 30.
For example, when the temperature of the storage compartment 14 is-9 ℃, the control unit 60 inquires the storage unit 50 that the corresponding voltage at the temperature is 2V, the control unit 60 controls the voltage of the adjustable power supply E to be 2V, and finally, under the catalytic action of the 2V voltage, the electrochromic layer 30 is entirely green, so that a user can judge the temperature of the storage compartment 14 according to the color of the electrochromic layer 30, and the door 20 automatically changes the color, thereby improving the intelligence and the man-machine interaction of the refrigerator 1.
For another example, when the humidity of the storage compartment 14 is 30RH (relative humidity), the control unit 60 queries the storage unit 50 that the corresponding voltage at the temperature is 3V, and the control unit 60 controls the voltage of the adjustable power supply E to be 3V, and finally, under the catalytic action of the voltage of 3V, the electrochromic layer 30 is made to be green as a whole.
In some further embodiments, the correspondence of the state information to the voltage of the electrochromic layer 30 may also be preconfigured to be continuous, so that the voltage of the electrochromic layer 30 can be continuously adjusted as the state information changes.
Referring to fig. 3, in some embodiments, the detection unit 40 may further include a temperature sensor 42, and the temperature sensor 42 is disposed inside the storage compartment 14 to detect the temperature of the storage compartment 14 and output temperature status information.

Referring to fig. 3, in some embodiments, the detection unit 40 may further include a humidity sensor 44, and the humidity sensor 44 is disposed inside the storage compartment 14 to detect the humidity of the storage compartment 14 and output humidity state information. The memory unit 50 stores a second correspondence relationship between the humidity state information and the voltage of the electrochromic layer 30.
Referring to fig. 3, in some embodiments, the refrigerator 1 may further include a time collecting unit 70, and the time collecting unit 70 is electrically connected to an input terminal of the control unit 60 to transmit time information to the control unit 60. The storage unit 50 stores a third correspondence of time information to the voltage of the electrochromic layer 30. The control unit 60 is further configured to adjust the voltage applied to the electrochromic layer 30 according to the third correspondence so that the color of the electrochromic layer 30 changes over time.
In this embodiment, the time collecting unit 70 may record the current time in real time and output the time information. The storage unit 50 stores a third correspondence of time information to the voltage of the electrochromic layer 30, which may be a different time period versus voltage relationship.
For example, before the refrigerator 1 is shipped, 08: the color of the door body 20 in the time period 00 to 12. The time acquisition unit 70 transmits time information to the control unit 60 in real time, and when the current time is 08: during the time period from 00 to 12, the control unit 60 controls the voltage of the adjustable power supply E to be 2V, and finally, under the catalytic action of the voltage of 2V, the entire electrochromic layer 30 is made to be light green, and during the time period from 12 to 20 at the present time, the control unit 60 controls the voltage of the adjustable power supply E to be 2.5V, and finally, under the catalytic action of the voltage of 2.5V, the entire electrochromic layer 30 is made to be dark green, so that the intelligence and the man-machine interaction of the refrigerator 1 are further improved.
In some embodiments, the temperature sensor 42, the humidity sensor 44, and the time acquisition unit 70 may be used alternatively, that is, only one status information or time information is used to adjust the color of the door 20.
