As shown in fig. 1, the present invention provides a display method for a washing machine, the display method including the steps of: s1, detecting the distance between the user and the washing machine; s2, comparing the distance with a preset display distance threshold value; and S3, selectively adjusting the brightness of the display device according to the comparison result of the distance and the preset display distance threshold.
In another aspect, the present invention also provides a washing machine, as shown in fig. 3, including a washing tub for accommodating an object to be washed; an illumination device for illuminating the interior of the washing drum; a display device for displaying a program and/or status information of the washing machine; a distance detecting device for detecting a distance between a user and the washing machine; and a control device that controls the illumination device and/or the display device based on a detection result of the distance detection device and according to the display method. The distance detection device can be a human body induction distance measurement device such as an infrared spectrum sensor, an ultrasonic distance measurement sensor or a camera, the distance detection device can be arranged on at least one side of the display device, and the distance detection device can also be arranged on a tray seat of the washing machine. In the process of detecting the distance, the distance between the user and the washing machine may be continuously detected, or the distance between the user and the washing machine may be intermittently detected. When the control device receives the distance signal detected by the distance detection device, the distance is compared with a preset display distance threshold or a preset illumination distance threshold, and according to the comparison result, the control device controls the washing machine to adjust the brightness of the display device, so that a user can clearly observe the running state information or the running program of the washing machine; or the on/off state of the lighting device is adjusted, so that a user can conveniently check the state of the washed object in the washing drum, and the use experience of the user is improved.

Under the arrangement modes of different washing drums, the arrangement positions of the lighting devices can be irradiated to the bottoms of the washing drums.
In a preferred embodiment, the predetermined display distance threshold comprises a first predetermined display distance threshold; in the step S3, the step of "selectively adjusting the brightness of the display device according to the comparison result between the distance and the preset display distance threshold" further includes: and S31, if the distance is less than the first preset display distance threshold, controlling the washing machine to increase the brightness of the display device to the first brightness. Specifically, when the distance is smaller than the first preset display distance threshold, it may be considered that the user is already within the range of the first preset display distance threshold, and in order to facilitate the user to clearly observe the operation state information or the operation program of the washing machine within the range of the first preset display distance threshold, the washing machine is controlled to increase the brightness of the display device to the first brightness, so that the purpose of adjusting the brightness of the display device according to the distance between the user and the washing machine is achieved, the display device can display the first brightness to meet the requirement of the user for observing the operation state information or the operation program of the washing machine, and further the use experience of the user is improved.
In the process, by setting the first preset display distance threshold, a conclusion whether the brightness of the display device is improved to the first brightness can be preliminarily given, so that the display device can adopt an optimal brightness mode under different conditions, the display device can display different brightness according to the distance between a user and the washing machine, the requirement of the user for observing the running state information or the running program of the washing machine is met, and the use experience of the user is improved. The first preset display distance threshold may be a maximum distance at which the user can observe information displayed by the display device, so that the user can timely observe the running state information or the running program displayed by the display device within a maximum range. Of course, the first preset display distance threshold is not limited to the maximum distance at which the user can observe the information displayed by the display device, and may be other distances, such as an experimental distance obtained by a person skilled in the art according to an experiment under a specific working condition, or an empirical distance obtained according to an experiment, as long as the requirement that the demarcation point determined by the first preset display distance threshold, which is used for increasing the brightness of the display device to the first brightness, can meet the display brightness is met.
In a preferred embodiment, the preset display distance threshold further includes a second preset display distance threshold; in the step S3, the step of "selectively adjusting the brightness of the display device according to the comparison result between the distance and the preset display distance threshold" further includes: s32, if the distance is smaller than a second preset display distance threshold, controlling the washing machine to increase the brightness of the display device to a second brightness; wherein the second brightness is greater than the first brightness. Specifically, when the distance is smaller than the second preset display distance threshold, it may be considered that the user is already within the range of the second preset display distance threshold, and in order to facilitate the user to clearly observe the operation state information or the operation program of the washing machine within the range of the second preset display distance threshold, the washing machine is controlled to increase the brightness of the display device to the second brightness, so that the purpose of adjusting the brightness of the display device according to the distance between the user and the washing machine is achieved, the display device can display the second brightness to meet the requirement of the user for observing the operation state information or the operation program of the washing machine, and further the use experience of the user is improved.
In the process, through setting of the second preset display distance threshold, a conclusion whether the brightness of the display device is improved to the second brightness can be further given, so that the display device can adopt an optimal brightness mode under different conditions, the display device can display different brightness according to the distance between the user and the washing machine, the requirement of the user for observing the running state information or the running program of the washing machine is met, and the use experience of the user is improved. The setting of the second preset display distance threshold can be flexibly adjusted and set according to actual conditions, as long as the requirement that the display brightness can be met by the demarcation point for switching from the brightness of the display device determined by the second preset display distance threshold to the second brightness is met.
The second preset display distance threshold is different from the first preset display distance threshold, and the example that the second preset display distance threshold is smaller than the first preset display distance threshold is further described below. When the distance is greater than or equal to the first preset display distance threshold, the user is not considered to be in the range of the first preset display distance threshold, and the user does not need to observe the running state information or the running program of the washing machine, so that the washing machine is controlled not to improve the brightness of the display device; when the distance is smaller than a first preset display distance threshold and the distance is greater than or equal to a second preset display distance threshold, the user can be considered to be in the range of the first preset display distance threshold, and in order to facilitate the user to clearly observe the running state information or the running program of the washing machine in the range of the first preset display distance threshold, the washing machine is controlled to improve the brightness of the display device to the first brightness; when the distance is smaller than the second preset display distance threshold, the user is considered to be within the range of the second preset display distance threshold, and in order to facilitate the user to clearly observe the operation state information or the operation program of the washing machine within the range of the second preset display distance threshold, the washing machine is controlled to increase the brightness of the display device to the second brightness, so that the purpose of adjusting the brightness of the display device according to the distance between the user and the washing machine is achieved, the display device can display the first brightness or the second brightness according to the judgment result of the distance to meet the requirement of the user for observing the operation state information or the operation program of the washing machine, and the use experience of the user is improved. In practical applications, the actual values of the first preset display distance threshold and the second preset display distance threshold may be obtained by those skilled in the art according to experiments or experience. Of course, it will be understood by those skilled in the art that the second preset display distance threshold may be larger than the first preset display distance threshold, as long as the requirement for increasing the brightness of the display device to a different brightness, which is determined by a different preset display distance threshold, is met.
In a preferred embodiment, the preset display distance threshold further includes a third preset display distance threshold; in the step S3, the step of "selectively adjusting the brightness of the display device according to the comparison result between the distance and the preset display distance threshold" further includes: s33, if the distance is smaller than a third preset display distance threshold, controlling the washing machine to increase the brightness of the display device to a third brightness; wherein the third brightness is greater than the second brightness. Specifically, when the distance is smaller than the third preset display distance threshold, it may be considered that the user is already within the range of the third preset display distance threshold, and in order to facilitate the user to clearly observe the operation state information or the operation program of the washing machine within the range of the third preset display distance threshold, the washing machine is controlled to increase the brightness of the display device to the third brightness, so that the purpose of adjusting the brightness of the display device according to the distance between the user and the washing machine is achieved, the display device can display the third brightness to meet the requirement of the user for observing the operation state information or the operation program of the washing machine, and further the use experience of the user is improved.
Preferably, the first brightness is a micro brightness, i.e., a brightness when less than half of the lamps of the display device are on; the second luminance is half luminance, i.e., luminance when half of the lamps of the display device are turned on; the third brightness is full brightness, i.e., brightness when the lamps of the display device are all on.
In the process, by setting the third preset display distance threshold, a conclusion about whether the brightness of the display device is improved to the third brightness can be further given, so that the display device can adopt an optimal brightness mode under different conditions, the display device can display different brightness according to the distance between the user and the washing machine, the requirement of the user for observing the running state information or the running program of the washing machine is met, and the use experience of the user is improved. Through repeated tests, observation, analysis and comparison of the inventor, when the third preset display distance threshold is determined to be the optimal visual distance for the user to observe the running state information or the running program displayed by the display device, the display scheme of the display device is optimal, namely, the brightness of the display device is increased to the third brightness within the optimal visual distance range, so that the requirement of the user for observing the running state information or the running program of the washing machine is met. In practical applications, the actual value of the third preset display distance threshold is not limited to the optimal sight distance of the user for observing the running state information displayed by the display device or running the program, and can be obtained by a person skilled in the art through experiments or experience.
The first preset display distance threshold, the second preset display distance threshold and the third preset display distance threshold are different from each other, and the third preset display distance threshold is smaller than the second preset display distance threshold, and the second preset display distance threshold is smaller than the first preset display distance threshold. When the distance is greater than or equal to the first preset display distance threshold, the user is not considered to be in the range of the first preset display distance threshold, and the user does not need to observe the running state information or the running program of the washing machine, so that the washing machine is controlled not to improve the brightness of the display device; when the distance is smaller than a first preset display distance threshold and the distance is greater than or equal to a second preset display distance threshold, the user can be considered to be in the range of the first preset display distance threshold, and in order to facilitate the user to clearly observe the running state information or the running program of the washing machine in the range of the first preset display distance threshold, the washing machine is controlled to improve the brightness of the display device to the first brightness; when the distance is smaller than the second preset display distance threshold and the distance is greater than or equal to the third preset display distance threshold, the user is considered to be within the range of the second preset display distance threshold, and in order to facilitate the user to clearly observe the operation state information or the operation program of the washing machine within the range of the second preset display distance threshold, the washing machine is controlled to improve the brightness of the display device to the second brightness; when the distance is smaller than the third preset display distance threshold, the user is considered to be within the range of the third preset display distance threshold, and in order to facilitate the user to clearly observe the operation state information or the operation program of the washing machine within the range of the third preset display distance threshold, the washing machine is controlled to increase the brightness of the display device to the third brightness, so that the purpose of adjusting the brightness of the display device according to the distance between the user and the washing machine is achieved, the display device can display the first brightness, the second brightness or the third brightness according to the judgment result of the distance so as to meet the requirement of the user for observing the operation state information or the operation program of the washing machine, and the use experience of the user is improved. In practical applications, actual values of the first preset display distance threshold, the second preset display distance threshold, and the third preset display distance threshold may be obtained by those skilled in the art according to experiments or experience. Of course, it can be understood by those skilled in the art that the third preset display distance threshold may be larger than the second preset display distance threshold, and the second preset display distance threshold is larger than the first preset display distance threshold, and the size relationship among the first preset display distance threshold, the second preset display distance threshold, and the third preset display distance threshold is not limited thereto, as long as the requirement for increasing the brightness of the display device to different brightness, which is determined by different preset display distance thresholds, is satisfied.
In a preferred embodiment, in step S2, at the same time or before the step of "comparing the distance with the preset display distance threshold", the display method further includes: s4, judging whether the distance is smaller than a preset illumination distance threshold value; s5, if the distance is smaller than the preset illumination distance threshold, adjusting the state of the illumination device according to the stay time of the user within the preset illumination distance threshold; and S6, if the distance is larger than or equal to the preset illumination distance threshold value, controlling the illumination device to be in a closed state. Specifically, when the distance is greater than or equal to the preset illumination distance threshold, which indicates that the user is out of the range of the preset illumination distance threshold, it may be determined that the user does not want to observe the condition in the washing tub, and the illumination device may be controlled to be in the off state. When the distance is smaller than the preset illumination distance threshold, the fact that the user is within the range of the preset illumination distance threshold is indicated, in order to accurately judge whether the user needs to observe the condition in the washing drum, the stay time of the user within the preset illumination distance threshold is further detected, whether the user needs to observe the condition in the washing drum is accurately judged, the situation that the user does not need to observe the condition in the washing drum is avoided, the lighting device is turned on, the waste of energy is avoided, and the use experience of the user is improved.
In the process, the conclusion that the lighting device is in the closed state or the open state can be preliminarily given through the setting of the preset lighting distance threshold value, so that the lighting device can adopt the optimal lighting mode under different conditions, the state of the lighting device can be adjusted according to the distance between the user and the washing machine, the requirement that the user observes the condition in the washing drum is met, and the use experience of the user is improved. The preset illumination distance threshold value can be flexibly adjusted and set according to actual conditions, and only the demarcation point which is determined by the preset illumination distance threshold value and enables the illumination device to be in the on state can meet the illumination requirement.
It should be further noted that the distance for determining whether to adjust the brightness of the display device and the distance for determining whether to adjust the state of the lighting device may be the same distance or different distances, that is, the distance for determining whether to adjust the brightness of the display device is the distance between the user and the display device, and the distance for determining whether to adjust the state of the lighting device is the distance between the housings of the washing machine.
Preferably, in the step S5, the step of adjusting the state of the lighting device according to the staying time of the user within the preset illumination distance threshold if the distance is less than the preset illumination distance threshold further includes: s51, if the stay time is larger than the preset time threshold, controlling the lighting device to be in an on state; and S52, if the stay time is less than or equal to the preset time threshold, controlling the lighting device to be in a closed state. Specifically, when the residence time is less than or equal to the preset time threshold, it may be considered that the user does not want to observe the conditions inside the washing drum, and if the user passes through the washing machine, the lighting device is controlled to be in the off state; if the stay time is longer than the preset time threshold, the user can be considered to observe the condition in the washing drum, and in order to enable the user to clearly observe the condition in the washing drum, the lighting device is controlled to be in an open state to light the inside of the washing drum, so that the user can conveniently view the state of the washed objects in the washing drum, and the use experience of the user is improved.
