Detailed Description
Fig. 1 is a schematic diagram of a refrigerator 10 according to one embodiment of the present invention. Fig. 2 is a control block diagram of the refrigerator 10 according to one embodiment of the present invention. The refrigerator 10 may generally include: the light source device includes a cabinet 110, a door (not shown), an internal light source 210, a light sensor 220, and a controller 300.
The cabinet 110 defines a storage compartment 120 therein for storing food. The storage compartment 120 may be divided into a freezing compartment, a refrigerating compartment, and a temperature-varying compartment according to storage temperature and function. The refrigerator 10 can be flexibly configured with the number and function of the storage compartments 120. And a door body provided at the front side of the cabinet 110 to open and close the storage compartment 120.
The internal light source 210 is installed inside the storage compartment 120, for example, the top of the storage compartment 120 or the rear wall of the storage compartment 120, and on one hand, the internal light source can be used for illuminating the inside of the storage compartment 120 after the door body is opened, and on the other hand, the internal light source can emit visible light for detecting the usage volume of the storage compartment 120 after the door body is closed. The internal light sources 210 may be one or more according to the size of the storage compartment 120 of the refrigerator 10, for example, one set of internal light sources 210 may be used for a storage compartment 120 with a small available volume (e.g., less than or equal to 30L), and multiple sets of internal light sources 210 may be used for a storage compartment 120 with a large available volume (e.g., greater than 30L). The internal light source 210 is preferably an LED light source, varied by adjusting the supply voltage and/or the conduction ratio. For example, the LED light source may be powered by a power supply with continuously adjustable voltage, and the power supply voltage may be changed during adjustment; for a power supply with a fixed voltage, for example, the brightness of the LED may be adjusted by adjusting the conduction ratio (or referred to as on-off ratio). For example, for a voltage of 12V, a voltage of 9.6V can be obtained by a conduction rate of 80%.
The light sensor 220 is also installed inside the storage compartment 120 for measuring the brightness inside the storage compartment 120. As the usage size of the usage volume of the storage compartment 120 changes, the reflection and blocking of light in the storage compartment 120 change, and the propagation characteristics of light also differ. Therefore, a technology for detecting the using volume of the refrigerator by using the rule that the brightness of the storage compartment 120 changes along with the change of the using volume appears. However, when the measurement result of the photosensor 220 is actually used to detect the used volume, it is found that the actually detected result may have a large deviation, and therefore, those skilled in the art mainly aim to improve the detection algorithm.
In the process of implementing the solution of the present embodiment, the inventor finds that the differences of the light emitting effects of the internal light sources of the same type using the same parameters in the storage compartment 120 may also occur due to the differences of the internal light sources, the light sensor 220 and the assembly of the internal components of the box 110, and the differences lead to the detection errors. In view of the problem of poor detection accuracy caused by the consistency, the refrigerator 10 and the method for setting the brightness of the internal light source of the refrigerator according to the present embodiment provide a detection environment with better consistency by adjusting the light emitting parameters of the internal light source 210.
The controller 300 in the refrigerator 10 of the present embodiment has a memory 320 and a processor 310, wherein a computer program 321 is stored in the memory 320, and the computer program 321 is used to implement the method for setting the brightness of the internal light source of the refrigerator according to any one of the following embodiments when executed by the processor 310. The processor 310 may be a central processing unit, or a digital processing unit, etc. The memory 320 is a variety of non-volatile memories such as, but not limited to, a read-only memory, a flash memory, a hard or solid state drive, or any other medium that can be used to carry or store desired program code in the form of instructions or data structures and that can be accessed by a computer.
Fig. 3 is a schematic view of a brightness setting method of an internal light source of a refrigerator according to an embodiment of the present invention, which may generally include:
step S302 is to obtain a trigger signal for the refrigerator 10 to enter the initialization setting mode, where the trigger signal may be a power-on start signal of the refrigerator 10 or an initialization instruction signal issued by a user.
In step S304, the internal light source 210 and the photosensor 220 inside the refrigerator 10 are turned on.
After the trigger signal is acquired, the parameter setting state of the internal light source 210 may be read first; in the case where the parameter setting state is not set, the initialization setting mode is automatically entered and the internal light source 210 and the light sensing sensor 220 are turned on.
And if the parameter setting state is set, outputting calibration prompt information to prompt a user or an operator whether recalibration is needed. After receiving the calibration instruction in response to the calibration prompt message, that is, after receiving the calibration operation instruction of the user or the operator, enter the initialization setting mode and turn on the internal light source 210 and the light sensor 220.
When the internal light source 210 is turned on, light may be emitted according to the initial default light emission parameters. After the step of entering the initialization setting mode and turning on the internal light source 210 and the light sensing sensor 220, the method may further include: detecting whether the state of the refrigerator 10 satisfies a preset initialization setting condition; if yes, executing the step of adjusting the light emitting parameters of the internal light source 210; if not, outputting an initialization prompt message to prompt the operator to adjust the refrigerator 10 to a state satisfying the initialization setting condition, and after the initialization setting condition is satisfied, performing a step of adjusting the light emitting parameters of the internal light source 210. The initialization setting condition may include: the door opening/closing signal of the refrigerator 10 indicates that the door is in a closed state and continues for a set time, and/or the fluctuation of the measured brightness of the light sensor 220 in the set time is less than a preset fluctuation threshold. Since the detection of the used volume generally needs to be performed when the door is closed, the door needs to be in a closed state for a set time period even at the time of initial setting.
By the above initialization conditions, it can be ensured that the door is kept closed and the internal light source 210 and the light sensor 220 work normally during the initialization process. In addition, it is necessary to ensure that the storage compartment 120 is empty when initialization is performed.
In step S306, the light emitting parameters of the internal light source 210 are adjusted to continuously change the light emitting intensity of the internal light source 210, for example, for an LED light source, the power supply voltage or the conduction rate thereof may be continuously changed.
Step S308, the measured brightness of the photosensor 220 is obtained, and the light-emitting parameters of the internal light source 210 when the measured brightness reaches the preset brightness range are recorded and saved. The above-mentioned luminance range may be set in advance according to the luminance required to detect the usage volume.
Step S310, exiting the initialization setting mode, and controlling the internal light source 210 to emit light according to the stored light emitting parameters when the refrigerator 10 performs the volume estimation.
The luminous parameters determined by the steps can ensure the consistency of the luminous when the using volume is detected, and are adaptive to the parameters of the calculation algorithm of the using volume of the refrigerator 10. For example, the step of estimating the volume of the refrigerator 10 may include: after the door closing signal of the refrigerator 10 is obtained, reading the stored light emitting parameters, and controlling the internal light source 210 to emit light according to the stored light emitting parameters; acquiring the measured brightness of the photosensor 220; and calculates the usage volume of the storage compartment 120 based on the measured brightness. The refrigerating state of the refrigerator 10 may also be adjusted according to the usage volume after calculating the usage volume of the storage compartment 120.
For example, after a door closing signal of the refrigerator 10 is acquired, the internal light source 210 and the light sensor 220 in the storage compartment 120 are started to detect the usage volume of the storage compartment 120; comparing the detected usage volume with the usage volume of the refrigerator 10 before the door is closed; if the detected usage volume is larger than the usage volume before the door is closed, the cold source driving the storage compartment 120 operates at a high power, so that the refrigerator 10 enters a quick cooling mode to rapidly reduce the temperature of the food just put in. The refrigerator 10 may also output the usage volume to the user terminal in a wireless manner, and output a food supplement prompting signal to the user when the usage volume is less than a preset volume threshold.
Fig. 4 is a flowchart of a brightness setting method of an internal light source of a refrigerator according to one embodiment of the present invention. The process comprises the following steps:
step S402, entering an initialization setting mode;
step S404, determining whether the parameter setting state of the light source 210 is set, that is, detecting whether the set light emitting parameter is stored;
step S406, turning on the internal light source 210 and the light sensor 220 inside the refrigerator 10 when the parameter setting state is not set;
step S408, determining whether the state of the refrigerator 10 meets an initialization setting condition, such as that the door is in a closed state and continues for a set time, or that the door is in a closed state for a set time and the fluctuation of the measured brightness of the photosensor 220 in the set time is less than a preset fluctuation threshold;
and step S410, outputting a door closing prompt under the condition that the door body is not closed.
Step S412, adjusting the light emitting parameters of the internal light source 210 to continuously change the light emitting intensity of the internal light source 210, for example, for an LED light source, the power supply voltage or the conduction rate thereof may be continuously changed;
step S414, obtaining the measured brightness of the photosensor 220, and determining whether the measured brightness reaches a preset brightness range;
step S416, recording and storing the light emitting parameters of the internal light source 210 when the measured brightness reaches the preset brightness range;
in step S418, the initialization setting mode is exited.
Fig. 5 is a flowchart for detecting a usage volume of the storage compartment in a brightness setting method of an internal light source of a refrigerator according to an embodiment of the present invention. The process of detecting the usage volume is performed during the usage of the refrigerator 10, and includes:
step S502, acquiring a door closing signal of the refrigerator 10;
step S504, reading a prestored lighting parameter of the internal light source 210, such as a prestored power supply voltage or a prestored conduction rate of the LED light source;
step S506, controlling the internal light source 210 to emit light according to the stored light-emitting parameters;
step S508, acquiring the measured brightness of the photosensor 220;
step S510, calculating the using volume of the storage chamber 120 according to the measured brightness;
in step S512, the cooling state of the refrigerator 10 is adjusted according to the usage volume.
By using the method of the embodiment, the internal light source 210 is controlled to emit light according to the stored light-emitting parameters during the volume estimation, so that the stability of the light-emitting intensity of the internal light source 210 is ensured, the consistency of the test conditions for detecting the internal use volume of the refrigerator 10 by using the light source 210 is higher, and the detection accuracy is ensured.
