Description

Technical Field

[0001] The present invention relates to the technical field of household appliances, and specifically provides a household appliance and a control method thereof. Background Art

[0002] With the advancement of science and technology and the improvement of people's living standards, the types of household appliances are becoming more and more diverse. In daily family life, people are increasingly relying on various household appliances, such as drum washing machines, dryers, dishwashers, shoe washers, etc. The display interface of each household appliance (including the power button, etc.) is usually printed on the door or cover, so that people can easily find the location of the display interface, turn on the drum washing machine through the buttons and knobs on the display interface, and set the corresponding operating parameters to use the household appliance to wash clothes, dry clothes, wash dishes, wash shoes, etc.

[0003] However, the method of printing the display interface on the control panel is often not beautiful enough, especially for some models with fashionable appearance, the printing method will affect the overall aesthetics of the product. For this reason, the display interface is usually made visible and invisible. When the household appliance needs to be used, the user touches the area where the display interface is located, and the display interface will light up, especially the power button will light up, so that the user can turn on the household appliance and set the corresponding parameters. However, because the display interface is usually integrated with the door or cover when the household appliance is not in use, the user usually cannot see the power button and cannot accurately find the area where the power button is located. Especially when the user is not familiar with the household appliance, it is even more difficult to find the area where the power button is located, which causes inconvenience to the user's operation and affects the user experience.

[0004] Accordingly, the art needs a new technical solution to solve the above problems. Summary of the invention

[0005] The present invention aims to solve the above technical problem, that is, to solve the problem in the prior art that the user cannot accurately find the position of the power button, resulting in inconvenience in operation.

[0006] In a first aspect, the present invention provides a control method for a household appliance, wherein the household appliance comprises a power button, wherein the power button is configured to turn on or off the household appliance.

[0007] The control method comprises:

[0008] When the household appliance is in a powered-off state, determining whether a human body enters a preset range of the household appliance;

[0009] When a human body enters the preset range, obtaining the height of the human body;

[0010] Obtaining the length of time the human body stays within the preset range;

[0011] The power button is selectively awakened based on the height and the stay duration.

[0012] In the preferred technical solution of the above control method, the step of "selectively waking up the power button based on the height and the stay time" further includes:

[0013] When the height is greater than a preset height and the stay time is greater than a first preset time, the power button is awakened.

[0014] In the preferred technical solution of the above control method, the control method further includes:

[0015] While or after waking up the power button, obtaining a wakeup duration for waking up the power button;

[0016] Determining whether a key press of the power key is received;

[0017] Determine whether there is still a target human body within the preset range;

[0018] Selectively determining a target flashing mode of the power button based on the wake-up duration, a judgment result of whether a key press of the power button is received, and a judgment result of whether a target human body is still within the preset range;

[0019] While or after determining the target flashing mode, controlling the power button to flash in the target flashing mode;

[0020] Wherein, the height of the target person is greater than the preset height.

[0021] In the preferred technical solution of the above control method, the step of "selectively determining the target flashing mode of the power key based on the wake-up duration, the judgment result of whether the key press action of the power key is received, and the judgment result of whether the target human body is still within the preset range" further includes:

[0022] If the wake-up time is less than the second preset time and no key press of the power key is received, the first flashing mode is determined to be the target flashing mode.

[0023] In the preferred technical solution of the above control method, the step of "selectively determining the target flashing mode of the power key based on the wake-up duration, the judgment result of whether the key press action of the power key is received, and the judgment result of whether the target human body is still within the preset range" further includes:

[0024] If the wake-up duration is greater than or equal to the second preset duration and less than the third preset duration, and no key press of the power button is received, the target flashing mode of the power button is further selectively determined based on the judgment result of whether there is still a target human body within the preset range.

[0025] In the preferred technical solution of the above control method, the step of "further selectively determining the target flashing mode of the power button according to the result of the judgment of whether there is still a target human body within the preset range" further includes:

[0026] If a target human body is located within the preset range, a second flashing mode is determined as the target flashing mode, wherein the flashing frequency of the second flashing mode is greater than the flashing frequency of the first flashing mode.

[0027] In the preferred technical solution of the above control method, the step of "further selectively determining the target flashing mode of the power button according to the result of the judgment of whether there is still a target human body within the preset range" further includes:

[0028] If there is no target human body within the preset range, the power button is turned off.

[0029] In the preferred technical solution of the above control method, the step of "selectively determining the target flashing mode of the power key based on the wake-up duration, the judgment result of whether the key press action of the power key is received, and the judgment result of whether the target human body is still within the preset range" further includes:

[0030] If the wake-up time is greater than or equal to the third preset time and no key press of the power button is received, the power button is turned off.

[0031] In the preferred technical solution of the above control method, the control method further includes:

[0032] While or after waking up the power button, obtaining the light intensity of the environment in which the household appliance is located;

[0033] The brightness of the power key is adjusted based on the light intensity.

[0034] In the technical solution of the present invention, when the household appliance is in the off state, it is determined whether a human body enters the preset range of the household appliance. When a human body enters the preset range, the height of the human body and the length of time the human body stays in the preset range are obtained, and the power button is selectively awakened based on the height and the length of time. In this way, even if the household appliance is currently in the off state and the power button is not lit, if a user approaches the household appliance, it is determined whether the user has a tendency to use the household appliance based on the height of the user and the length of time the user stays in the preset range, and then the power button is selectively awakened. When the user has a tendency to use the household appliance, the power button is awakened in time and the power button is lit, so that the user can easily find the power button and turn on the household appliance for use, thereby effectively improving the user experience.

[0035] Furthermore, at the same time or after waking up the power button, the wake-up time of the power button is obtained, and it is determined whether the key operation of the power button is received, and whether the target human body is still within the preset range of the household appliance. Based on the wake-up time, the judgment result of whether the key operation of the power button is received, and the judgment result of whether the target human body is within the preset range of the household appliance, the target flashing mode of the power button is selectively determined, and at the same time or after the target flashing mode is determined, the power button is controlled to flash in the target flashing mode. In this way, after waking up the power button, the user can be better reminded of the location of the power button when the user wants to use the household appliance, and the power button can be turned off in time when the user does not want to use the household appliance. According to the actual needs of the user, the power button is controlled to flash in the target flashing mode or turn off the power button, thereby preventing the user from finding the power button, and at the same time preventing the power button from lighting up when it is not needed, so as to better serve the user and effectively improve the user experience.

[0036] Furthermore, while or after waking up the power button, the light intensity of the environment in which the household appliance is located is obtained, and the brightness of the power button is adjusted based on the light intensity, so that the power button lights up with an appropriate brightness. This can more clearly and specifically remind the user of the location of the power button, avoiding the situation where the brightness of the power button is too low or the surroundings are too bright for the user to see, thereby better reminding the user of the location of the power button.

[0037] In a second aspect, the present invention further provides a household appliance, comprising a control module, wherein the control module is configured to execute the household appliance control method described in any of the aforementioned solutions.

[0038] It should be noted that the household appliance has all the technical effects of the aforementioned household appliance control method, which will not be repeated here. BRIEF DESCRIPTION OF THE DRAWINGS

[0043] Figure 4 The present invention is a flowchart of adjusting the brightness of a power button according to light intensity according to an embodiment of the present invention. DETAILED DESCRIPTION

[0044] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the scope of protection of the present invention. Although this embodiment is described by taking a drum washing machine as an example, it can also be applied to other types of household appliances such as a pulsator washing machine, a washer-dryer, a dryer, a dishwasher, and a shoe washing machine.

[0045] It should be noted that, in the description of the present invention, the terms "first" to "third" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance. In addition, in the description of the present application, unless otherwise clearly specified and limited, the terms "connected" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be internal communication between two elements. For those skilled in the art, the specific meanings of the above terms in the present application can be understood according to the specific circumstances.

[0046] Based on the problem that the user cannot accurately find the area where the display interface is located in the current method where the display interface lights up only after the user touches the display interface, the present invention selectively wakes up the power button based on the height and length of stay of a person when a person enters the preset range of the drum washing machine, so that the power button can be woken up and lit up in time when the user is inclined to use the drum washing machine, making it easier for the user to find the power button, thereby effectively improving the user experience.

[0047] In the present invention, the drum washing machine includes a machine body and a door body pivotally arranged on the machine body, wherein a washing drum is arranged in the machine body, and the washing drum can rotate relative to the machine body. A clothing delivery opening is provided on the side of the machine body, and the clothing delivery opening is communicated with the washing drum. When the door body is pivotally opened relative to the machine body, the clothing delivery opening is exposed to the environment, and clothing can be delivered into the washing drum through the clothing delivery opening. When the door body is pivotally closed relative to the machine body, the clothing delivery opening can be closed. After the door body is closed, the drum washing machine can be started to wash the clothing delivered into the washing drum.

[0048] In the present invention, a control panel is provided at a position above the door body of the machine body, and the control panel includes a touch screen and a display computer board, and the display computer board is provided close to the touch screen. The touch screen is generally black, and is provided with a plurality of touch buttons and a display area, and the touch buttons include a touch power button, and the drum washing machine can be turned on or off by touching the touch power button, and the washing parameters, the operating status of the drum washing machine, etc. can be displayed through the display area. When the drum washing machine is not started, the touch screen is black, and the specific positions of the touch power button and the display area cannot be seen at this time. It should be noted that for the convenience of explanation, the power button is used instead of the touch power button for the following description.

[0049] Specifically, the display computer board is provided with several LED indicators and touch sensing areas. The touch sensing areas are arranged corresponding to the touch buttons on the touch screen, and are used to receive touch actions from the touch buttons, and transmit touch signals to the drum washing machine, thereby controlling the operation procedures of the drum washing machine. For example, when the user's finger touches or approaches the touch sensing area of ​​the touch screen corresponding to the power button, it can be considered that the power button is pressed, and the drum washing machine is started or turned off. An LED indicator is arranged in the touch button, and the display computer board can light up or turn off the corresponding LED indicator according to the received instructions. For example, the LED indicator arranged in the power button can be controlled to light up. Alternatively, the LED indicator can be turned on or off by the user touching the power button.

[0050] It should be noted that the control panel may also include a touch screen, a sensing spring and a circuit control board, one end of the sensing spring is connected to the touch screen and the other end is connected to the circuit control board. The touch screen is provided with multiple touch buttons and display areas, and each touch button is configured with a sensing spring. When a user touches a touch button, the corresponding sensing spring is squeezed and transmits a signal to the circuit control board, and then the corresponding operation procedure is implemented through the circuit control board. Similarly, an LED indicator light is provided in the touch button, and the circuit control board can light up or turn off the corresponding LED indicator light according to the received instruction. Without departing from the basic principles of the present application, those skilled in the art can flexibly select the specific setting method of the control panel according to the specific application scenario, as long as the power button is not visible when the drum washing machine is turned off and the power button can be lit when the power button is awakened.

[0051] In the present invention, the drum washing machine is also equipped with a human body detection module, through which it is possible to detect whether a human body has entered the preset range of the drum washing machine, and at the same time, it is possible to detect the height of the human body. It should be noted that the human body detection module can be set on the door body of the drum washing machine, the front side of the body, or other possible positions. Those skilled in the art can flexibly select the specific setting position of the human body detection module according to the specific application scenario, as long as the human body detection module can detect whether a human body has entered the preset range of the drum washing machine, and detect the height of the human body when a human body enters the preset range.

[0052] It should be noted that the human body detection module can be but is not limited to an infrared detection module, a radar detection module, an infrared thermal imaging detector, an image acquisition device, etc.

[0053] Taking the human body detection module as an infrared thermal imaging detector as an example, the infrared thermal imaging detector can identify and receive the heat emitted by the organism around the drum washing machine, and draw the infrared thermal image of the organism according to the difference between the temperature of the organism and the ambient temperature of the drum washing machine, extract the outer contour of the organism in the infrared thermal image, and match the outer contour with the contour of the target body in the preset model library, so that it can accurately determine whether there is a human body in the infrared thermal image. Then, based on the infrared thermal image, the height of the organism in the infrared thermal image is determined. It should be noted that the preset model library pre-stores the contours of people of various genders, heights and body shapes.

[0054] It should be noted that the human body detection module can be real-time detection or detection according to a preset time interval, wherein the preset time interval can be 15 seconds, 30 seconds, 1 minute, 3 minutes, etc. Of course, these preset time intervals are only exemplary descriptions and are not restrictive. Those skilled in the art can flexibly choose in actual applications, and no matter how to adjust and set the preset time interval, as long as it can accurately detect whether a human body enters the preset range.

[0055] It should be noted that the preset range may be the detection range when the human body detection module works normally, or may be a range pre-set by a person skilled in the art based on experiments or experience. The preset range may refer to a range within a certain straight-line distance from the drum washing machine, such as 0.2m, 0.5m, 0.8m or 1m, and those skilled in the art may flexibly adjust and set the preset range.

[0056] In the present invention, a light detection module is arranged on the drum washing machine, and the light intensity of the environment where the drum washing machine is located can be detected by the light sensor.

[0057] It should be noted that the light detection module can be, but is not limited to, a light sensor or an image acquisition device. Taking the light detection device as a light sensor as an example, the light sensor can convert light intensity into an electrical signal, which is then processed by an analog-to-digital processing circuit and output. Those skilled in the art can flexibly select the specific type of light detection device as long as the light intensity of the indoor space where the drum washing machine is located can be obtained.

[0058] In the present invention, the drum washing machine also includes a control module, which is connected to the above-mentioned touch screen, human body detection module, and light detection module, and can selectively wake up the power button based on body height and stay time. After waking up the power button, it can determine the target flashing mode of the power button or turn off the power button according to the wake-up time, the judgment result of whether the power button action is received, and the judgment result of whether the target human body is still within the preset range. After determining the target flashing mode, it can control the power button to flash in the target flashing mode, and can adjust the brightness of the power button according to the light intensity of the environment in which the drum washing machine is located.

[0059] It should be noted that such a control module may physically be a control chip of the drum washing machine itself, or a controller specifically used to execute the method of the present application, or a functional module or functional unit of a general controller.

[0060] Combine the following Figures 1 to 4 To illustrate possible implementations of the household appliance control method of the present invention.

[0061] like Figure 1As shown, in a possible implementation manner, the control method of the present invention includes:

[0062] S100: When the drum washing machine is in the off state, determining whether a human body enters into a preset range of the drum washing machine;

[0063] S101: When a person enters a preset range, obtaining the height of the person;

[0064] S102: Obtaining the length of time the human body stays within a preset range;

[0065] S103: Selectively wake up the power button based on the height and the stay time.

[0066] In S100, when the drum washing machine is in the off state, the control panel of the drum washing machine is generally black, and the power button cannot be seen by naked eyes. At this time, the human body detection module detects whether a human body enters the preset range of the drum washing machine.

[0067] In S101, if it is detected in S100 that a human body enters the preset range, it means that the human body is approaching the drum washing machine and may use the drum washing machine. At this time, the height of the human body is obtained through the above-mentioned human body detection module.

[0068] If no human body is detected to enter the preset range in S100, the human body detection module continues to detect. When a human body is detected to enter the preset range, S101 is executed.

[0069] In S102, the length of time the human body stays within the preset range is obtained.

[0070] It should be noted that the drum washing machine can be equipped with a timing module, which starts timing when it is determined in S100 that a human body enters the preset range, and accumulates the time the human body stays in the preset range, which is the length of time the human body stays in the preset range.

[0071] It should be noted that, although the above is explained by taking the example of first obtaining the height and then obtaining the dwell time, that is, executing S101 first and then executing S102, it is obviously only an exemplary explanation and is not restrictive. Obviously, S101 and S102 can also be executed at the same time, or S102 can be executed first and then S101. Without deviating from the basic principles of the present application, technical personnel in this field can flexibly choose the order of executing S101 and S102 according to the specific application scenario, as long as they can accurately judge the user's tendency.

[0072] In S103, based on the height obtained in S101 and the stay time obtained in S102, it is determined whether the person has the inclination to use the drum washing machine based on the height and the stay time. If so, the power button is awakened; if not, the power button is not awakened.

[0073] Through the above control method, the power button can be timely awakened and lit when the user is ready to use the drum washing machine, so that the user can quickly find the power button and use the power button to start the drum washing machine to wash clothes. It is also possible not to wake up the power button when the user is not ready to use the drum washing machine, thereby reducing power consumption. At the same time, it can also be made basically the same color as the control panel to ensure the overall aesthetics of the drum washing machine, thereby effectively improving the user experience.

[0074] In a possible implementation, when a person enters the preset range of the drum washing machine, it is determined whether to wake up the power button based on the height of the person and the length of time the person stays in the preset range. Figure 2 To illustrate possible implementation methods of selectively waking up the power button based on height and stay time.

[0075] like Figure 2 As shown, in a possible implementation manner, the control method of the present invention further includes:

[0076] S200: obtaining the height of the human body;

[0077] S201: Determine whether the height is greater than a preset height, if so, execute S203, if not, execute S202;

[0078] S202: Do not wake up the power button;

[0079] S203: Obtaining the length of time the human body stays within the preset range;

[0080] S204: Determine whether the duration is greater than a first preset duration, if so, execute S205, if not, execute S202;

[0081] S205: Wake up the power button.

[0082] In S200, similar to the above S101, the height of the person who enters the preset range of the drum washing machine is obtained through the above human detection module.

[0083] In S201, based on the height obtained in S200, it is determined whether the height is greater than a preset height.

[0084] If the height is less than or equal to the preset height, for example, the height obtained in S200 is 130 cm and the preset height is 150 cm, it means that the person is a child who may just run to play near the drum washing machine, and children usually do not have the ability to operate the drum washing machine independently. At this time, the power button is not awakened, that is, S202 is executed.

[0085] If the height is greater than the preset height, for example, the height obtained in S200 is 160 cm and the preset height is 150 cm, it means that the person has the ability to autonomously operate the drum washing machine and has the possibility of using the drum washing machine. At this time, the length of time the person stays in the preset range is further obtained, that is, S203 is executed.

[0086] In S204, based on the stay duration acquired in S203, it is determined whether the stay duration is greater than a first preset duration.

[0087] If the dwell time is less than or equal to the first preset time, for example, the dwell time obtained in S203 is 10 seconds and the first preset time is 30 seconds, it means that the human body is just passing by the drum washing machine and is not going to use the drum washing machine. At this time, the power button is not awakened, that is, S202 is executed.

[0088] If the dwell time is longer than the first preset time, for example, the dwell time obtained in S203 is 1 minute and the first preset time is 30 seconds, it means that the person is ready to use the drum washing machine. At this time, the power button is awakened, that is, S205 is executed. For example, an instruction to light up the LED indicator corresponding to the power button is sent to the display control panel, and the display control panel controls the LED indicator set in the power button to light up, so that the power button can be lit.

[0089] Through the above control method, the tendency of the human body to use the drum washing machine is judged based on the comparison result of the height of the human body entering the preset range with the preset height, and the comparison result of the human body's stay time in the preset range with the first preset time, and then it is determined whether to wake up the power button or not, so as to serve the user more accurately and avoid wasting electricity.

[0090] It should be noted that, although the above is explained by first obtaining the height and determining whether the height is greater than the preset height, and then obtaining the stay time and determining whether the stay time is greater than the first preset time, it is obviously also possible to first obtain the stay time and determine whether the stay time is greater than the first preset time, and then obtain the height and determine whether the height is greater than the preset height, or to obtain the height and the stay time at the same time, and determine whether the height is greater than the preset height and whether the stay time is greater than the first preset time. Without departing from the basic principles of the present application, those skilled in the art can flexibly choose the order of executing the above steps according to the specific application scenario, as long as they can accurately determine whether the human body entering the preset range of the drum washing machine has the tendency to use the drum washing machine, and wake up or not wake up the power button according to the tendency.

[0091] In a possible implementation, after waking up the power button, the drum washing machine may not be turned on because the user did not see the power button, the user changed his mind, etc. Keeping the power button in the awake state will waste energy and violate the purpose of this application. In this application, the target flashing mode of the power button is determined based on the wake-up duration, the judgment result of whether the power button action is received, and the judgment result of whether there is still a human body within the preset range. After determining the target flashing mode, the power button is controlled to flash in the target mode to better remind the user of the area where the power button is located by flashing, thereby improving the efficiency of the user in finding the power button. The following is combined with Figure 3 To illustrate the possible implementation method of the present application for determining the target flashing mode of the power button or turning off the power button based on the wake-up duration, the judgment result of whether the power button press action is received, and the judgment result of whether there is still a human body within a preset range after the power button is woken up.

[0092] like Figure 3 As shown, in a possible implementation manner, the control method of the present invention further includes:

[0093] S300: wake up power button;

[0094] S301: Determine whether a power button press action is received, if yes, execute S302, if no, execute S303;

[0095] S302: Controlling the drum washing machine to execute the received instruction;

[0096] S303: Obtaining the wake-up time of the wake-up power button;

[0097] S304: Determine whether the wake-up duration is less than the second preset duration, if so, execute S305, if not, execute S306;

[0098] S305: Determine the first flickering mode as the target flickering mode;

[0099] S306: Control the power button to flash in a first flashing mode;

[0100] S307: Determine whether the wake-up duration is greater than or equal to the third preset duration, if so, execute S308, if not, execute S309;

[0101] S308: Turn off the power button;

[0102] S309: Determine whether there is still a target human body within the preset range, if yes, execute S310, if no, execute S308;

[0103] S310: Determine the second flickering mode as the target flickering mode;

[0104] S311: Control the power button to flash in the second flashing mode.

[0105] In S300, similar to S205, the LED indicator light set in the power button can be controlled to light up, so that the power button is lit. Obviously, the power button can also be awakened by other methods.

[0106] In S301, after the power button is awakened in S300, it is determined whether a key press of the power button is received. For example, when the user touches the touch sensing area of ​​the corresponding power button with a finger and the capacitance value reaches a preset value, it can be considered that the power button is pressed, and at this time it can be considered that the key press of the power button is received.

[0107] If the power button is pressed, it means that the user has pressed the power button. At this time, the drum washing machine is controlled to execute the received instruction, that is, to execute S302. That is, the drum washing machine is controlled to start up, and the drum washing machine is operated after the washing parameters are set or selected. It should be noted that the washing parameters of the drum washing machine can be manually selected by the user according to the amount and material of the clothes, or can be determined by the drum washing machine itself according to the weight and material of the clothes put into the washing drum.

[0108] If the power button is not pressed, it means that the user may not have found or seen the power button. In this case, the wake-up time of the power button is obtained, that is, S303 is executed. For example, the wake-up time can be obtained by a timing module configured on the drum washing machine. The timing starts when the power button is awakened in S300 or S205, and the accumulated time of the power button is awakened is the wake-up time.

[0109] In S304, based on the wake-up duration acquired in S303, it is determined whether the wake-up duration is less than a second preset duration.

[0110] If the wake-up time is less than the second preset time, for example, the wake-up time obtained in S303 is 30 seconds and the second preset time is 2 minutes, it means that the power button is awakened for a short time, and the user may be doing other activities such as putting clothes or detergent in, and has not been able to press the button yet. At this time, the first flashing mode is determined as the target flashing mode, that is, S305 is executed.

[0111] In S306, after determining in S305 that the target flashing mode is the first flashing mode, the power button is controlled to flash in the first flashing mode. For example, the first flashing mode is a mode of being on for a first duration and off for a first duration, that is, the power button is made to flash in a mode of being on for a first duration and off for a first duration to remind the user of the location of the power button.

[0112] It should be noted that, the target flashing mode may be determined to be the first flashing mode in S305 and the power button may be controlled to flash in the first flashing mode, that is, S306 may be executed while S305 is executed.

[0113] If the wake-up time is greater than or equal to the second preset time, it is further determined whether the wake-up time is greater than or equal to the third preset time, that is, S307 is executed.

[0114] If the wake-up time is greater than or equal to the third preset time, for example, the wake-up time obtained in S303 is 15 minutes, the second preset time is 2 minutes, and the third preset time is 10 minutes, it means that the power button has been awakened for a long time, and the user has not pressed any button, which means that the user may not intend to use the drum washing machine to wash clothes, but just stayed near the drum washing machine for a short time. At this time, the power button is turned off, that is, S308 is executed to avoid wasting power.

[0115] If the wake-up time is less than the third preset time, that is, the wake-up time is greater than or equal to the second preset time and less than the third preset time, for example, the wake-up time obtained in S303 is 5 minutes, the second preset time is 2 minutes, and the third preset time is 10 minutes. This means that the power button has been awakened for a while. At this time, the user may or may not intend to use the drum washing machine. At this time, the human body detection module is further used to determine whether the target human body is still within the preset range, that is, S309 is executed.

[0116] It should be noted that the height of the target person is greater than the preset height. In other words, as long as the height of the person within the preset range is greater than the preset height in S201, it can be considered that there is still a target person within the preset range.

[0117] If there is still a target human body within the preset range, it means that there is currently a human body within the preset range and the height of the human body is greater than the preset height. The human body may be the same person as the human body in the previous S101 and S200, or may not be the same person. However, they are all people who use the drum washing machine and have the ability to operate the drum washing machine. At this time, the second flashing mode is determined as the target flashing mode, that is, S310 is executed.

[0118] In S311, after determining in S310 that the target flashing mode is the second flashing mode, the power button is controlled to flash in the second flashing mode. The flashing frequency of the second flashing mode is greater than the flashing frequency of the first flashing mode. This can make the power button more eye-catching and better remind the user of the location of the power button.

[0119] It should be noted that the flashing frequency of the power button is determined by the duration of the power button on and off. When the duration of the power button on remains unchanged, the duration of the off is shortened and the flashing frequency increases. The duration of the power button on is shortened and the duration of the off is also shortened, and the flashing frequency also increases. For example, the second flashing mode is a mode of a first duration on and a second duration off, wherein the second duration is smaller than the first duration, that is, the power button flashes in a mode of a longer first duration on and a shorter second duration off, which speeds up the flashing frequency compared to the mode of a first duration on and a first duration off. For another example, the second flashing mode is a mode of a second duration on and a second duration off, wherein the second duration is smaller than the first duration, that is, the power button flashes in a mode of a shorter second duration on and a shorter off, which speeds up the flashing frequency compared to the mode of a first duration on and a first duration off.

[0120] It should be noted that the target flashing mode may be determined as the second flashing mode in S310 and the power button may be controlled to flash in the second flashing mode, that is, S311 may be executed while S310 is executed.

[0121] If there is no target human body within the preset range, it means that there is no human body within the preset range at present, or there is a human body within the preset range but the height of the human body is less than the preset height, and the person who entered the preset range before only stayed for a short time and then left, and did not intend to use the drum washing machine. At this time, the power button is turned off, which means executing S308 to avoid wasting electricity.

[0122] Through the above control method, after the power button is awakened, when the user has the inclination to use the drum washing machine, the power button is made to flash in the first flashing mode or the second flashing mode, and the flashing frequency of the second flashing mode when the awakening time is longer is higher than the flashing frequency of the first flashing mode when the awakening time is shorter, so as to better remind the user of the location of the power button, and turn off the power button in time when the user has no inclination to use the drum washing machine, so as to reduce power consumption. In this way, the power button can be controlled to flash in a target flashing mode or turn off the power button according to the actual needs of the user, thereby preventing the user from finding the power button, and at the same time preventing the power button from lighting up when it is not needed, so as to better serve the user and effectively improve the user experience.

[0123] It should be noted that it is also possible to determine whether a key press of the power key is received while the power key is awakened, that is, to execute S301 while executing S300.

[0124] It should be noted that, when it is determined in S301 that no key press of the power button is received, the power can be turned off directly. Obviously, when it is determined in S304 that the wake-up duration is greater than or equal to the second preset duration, the power button can be turned off directly. When it is determined in S307 that the wake-up duration is less than the third preset duration, the second flashing mode can be directly determined as the target flashing mode, or the first flashing mode can still be determined as the target flashing mode.

[0125] In a possible implementation, after the power button is awakened, the power button is lit, but the user cannot clearly see the lit power button because the brightness is not enough or the surrounding environment is too bright. The present application can adjust the brightness of the power button based on the light intensity of the drum washing machine's environment, so that the power button can be displayed more clearly to the user, allowing the user to see the power button more clearly. Figure 4 To illustrate possible implementation methods of adjusting the brightness of the power button according to light intensity.

[0126] like Figure 4 As shown, in a possible implementation manner, the control method of the present invention further includes:

[0127] S400: Obtaining the light intensity of the environment where the drum washing machine is located;

[0128] S401: Adjust the brightness of the power button based on the light intensity.

[0129] In S400, after the power button is awakened, that is, after S205 or S300 is executed, the light intensity of the environment in which the drum washing machine is located is obtained through the light detection module.

[0130] In S401, the brightness of the power button is adjusted based on the light intensity obtained in S400, so that the power button lights up with a more appropriate brightness. For example, the drum washing machine is placed in the bathroom, the bathroom light is not turned on, and the light intensity of the drum washing machine is relatively low. At this time, the power button is controlled to light up with normal brightness, and the user can see the power button. For another example, the drum washing machine is placed on the balcony, and the weather is clear that day, the light intensity of the drum washing machine is relatively strong. At this time, the power button needs to be controlled to light up with a larger brightness so that the user can clearly see the power button.

[0131] It should be noted that the brightness of the power button can be achieved by controlling the brightness of the LED indicator light inside the power button, that is, the brightness of the power button corresponds to the brightness of the LED indicator light. The brightness of the LED indicator light can be adjusted by adjusting the voltage supplied to the LED indicator light, or adjusting the resistance inside the LED indicator light, or adjusting the current flowing through the LED indicator light, or adjusting the dimmer configured for the LED indicator light, thereby achieving the purpose of adjusting the brightness of the power button.

[0132] It should be noted that when determining the brightness of the power button based on light intensity, the light intensity obtained in S400 can be compared with the preset intensity. When the light intensity is less than the preset intensity, the brightness of the power button is determined to be the first brightness. When the light intensity is greater than or equal to the preset intensity, the brightness of the power button is determined to be the second brightness, wherein the first brightness is less than the second brightness.

[0133] Obviously, it is also possible to pre-build a brightness database, in which light intensity ranges and the brightness of the power button corresponding to each range are pre-stored, and the light intensity obtained in S400 is matched with each light intensity range in the brightness database to find the light intensity range including the light intensity, and the brightness of the power button corresponding to the light intensity range is determined as the final brightness of the power button. Of course, it is also possible to pre-set a comparison table, in which each light intensity range corresponds to the brightness of the power button one by one, and the light intensity obtained in S400 is compared with each light intensity range in the comparison table, and the brightness of the power button corresponding to the light intensity range that is successfully compared is determined as the final brightness of the power button.

[0134] Without departing from the basic principles of the present application, those skilled in the art can flexibly select a specific method for determining the brightness of the power button based on light intensity according to specific application scenarios, as long as an appropriate brightness can be determined so that the user can see the power button more easily.

[0135] Through the above control method, the power button can be lit with a more appropriate brightness to make the power button more conspicuous, avoiding the situation where the user cannot see the power button due to low brightness of the power button or too bright surroundings, thereby better reminding the user of the location of the power button.

[0136] It should be noted that the light intensity of the environment in which the drum washing machine is located may also be obtained while the power button is awakened, that is, S400 is executed while S205 or S300 is executed.

[0137] It should be noted that after waking up the power button, it is also possible not to obtain the light intensity of the environment in which the drum washing machine is located and adjust the brightness of the power button according to the light intensity, but to directly control the power button to light up at a fixed brightness.

[0138] It should be noted that the specific values ​​of the above-mentioned preset time interval, preset range, height, preset height, stay time, first preset time, wake-up time, second preset time, and third preset time are merely exemplary and not restrictive. Without departing from the basic principles of the present application, technical personnel in this field can flexibly select the specific values ​​of the above-mentioned time durations, preset ranges, and heights according to specific application scenarios, as long as they can accurately determine whether the user has the tendency to use the drum washing machine and then accurately wake up the power button and control the power button to flash or turn off the power button.

[0139] In summary, in the preferred technical solution of the present invention, when a human body enters the preset range of the drum washing machine, the user's height and the length of time the user stays in the preset range are used to determine whether the user has a tendency to use the drum washing machine. When the user has a tendency to use the drum washing machine, the power button is awakened in time and the power button is lit, so that the user can easily find the power button and turn on the drum washing machine for use, thereby effectively improving the user experience. After the power button is awakened, the target flashing mode of the power button is determined according to the awakening time, the judgment result of whether the key operation of the power button is received, and the judgment result of whether the target human body is located in the preset range of the drum washing machine, and the power button is controlled to flash in the target flashing mode, or the power button is turned off, so as to better remind the user, and at the same time, the power button can be turned off in time when it is not needed to reduce power consumption. After the power button is awakened, the brightness of the power button is adjusted based on the light intensity of the environment in which the drum washing machine is located, so that the power button is lit with a suitable brightness, so as to better remind the user of the location of the power button.

[0140] In addition, the present invention also provides a household appliance, which includes a control module, and the control module is configured to execute the aforementioned control method of the household appliance.

[0141] It should be noted that the household appliance has all the technical effects of the aforementioned household appliance control method, which will not be repeated here.
