For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0048] like Figures 1 to 3 As shown, the present invention provides a control method for a washing device and a washing device.

[0049] In one aspect, a control method for a washing device is provided.

[0050] The washing device comprises a stain detection device and a display device;

[0051] The control method comprises:

[0052] The stain detection device performs stain detection on the washing water / rinsing water;

[0053] The display device is controlled to display the content detected by the stain detection device and used to reflect the degree of cleaning / rinsing of the laundry.

[0054] The control method of the washing machine provided by the present invention enables the user to know the degree of cleanliness or rinsing of the laundry directly through the display device during the washing or rinsing process, so that the user can make the next step response according to the washing or rinsing situation and wash or rinse the laundry cleanly.

[0055] On the other hand, a washing device using the control method of the washing device is also provided.

[0056] Embodiment 1

[0057] like Figure 1 and Figure 2 As shown, this embodiment provides a control method for a washing device.

[0058] The washing device comprises a stain detection device and a display device;

[0059] The control method comprises:

[0060] The stain detection device performs stain detection on the washing water / rinsing water;

[0061] The display device is controlled to display the content detected by the stain detection device and used to reflect the degree of cleaning / rinsing of the laundry.

[0062] The washing device used in the control method of the washing device in this embodiment is a washing machine, wherein a stain detection device is provided in the washing tub of the washing machine, and a display device is also provided on the washing machine, wherein the stain detection device and the display device are communicatively connected.

[0063] The control method includes: a user puts the laundry into a washing tub and starts washing. As washing proceeds, a stain detection device detects information related to stains in washing water or rinsing water, and then sends the detected information related to stains to a display device, which displays the detected information related to stains. The user can know the degree of cleanliness or rinsing of the laundry through the information displayed on the display device.

[0064] In another solution of this embodiment, the stain detection device and the display device are not in communication connection, and both are in communication connection with the control system of the washing machine. The stain detection device sends the detected stain-related information to the control system of the washing machine, and the control system processes the information and sends it to the display device, which displays the stain-related information.

[0065] This embodiment also includes that the display device is provided with a digital tube for displaying the degree of washing / rinsing.

[0066] The display device directly displays the stain content change rate or the stain content value.

[0067] The detection device used in this scheme is an ultraviolet spectrum sensor, which detects the stain content of washing water by ultraviolet absorption spectroscopy. The ultraviolet spectrum sensor uses ultraviolet absorption spectroscopy to detect the stain content. The ultraviolet absorption spectroscopy detects the amount of the substance by the corresponding relationship between the substance and its ultraviolet visible spectrum when the substance absorbs light of a specific wavelength to reach the maximum value. The stains include a variety of substances that cannot be detected by conventional sensors. Conventional sensors, such as infrared tube sensors, cannot detect organic soluble stains, including oily stains, proteins, laundry detergents and emulsions, while the ultraviolet spectrum sensor can detect insoluble particles while detecting the above-mentioned organic soluble stains. Since organic soluble stains include the main types of dirt on clothes, during the washing process, by performing real-time and accurate detection of the amount of dissolution, the degree of washing or rinsing of the clothes can be more accurately displayed.

[0068] In the scheme of this embodiment, when a digital tube for displaying the degree of cleaning / rinsing is provided on the display device, the numerical value of the rate of change of the stain content is displayed on the digital tube to indicate the degree of cleaning during the washing process, and the numerical value of the stain content is displayed on the digital tube to indicate the degree of rinsing during the rinsing process.

[0069] In this scheme, whether the clothes are washed clean is explained by the change rate of the stain content. Generally speaking, washing can be divided into three stages. The first stage is that the stains on the clothes are quickly dissolved in the washing water. At this time, the stain content in the washing water increases rapidly. The change rate of the stain content in this stage is the largest. As the washing progresses, it enters the second stage. The second stage is that the stains on the clothes are dissolved in the washing water under the action of the impeller or lifting ribs. At this time, the stain content in the washing water increases slowly, and the change rate of the stain content in this stage is large. As the washing progresses, it enters the third stage. In this stage, the clothes are washed more and more cleanly, and the stain content dissolved in the washing water does not increase or increases slowly. The change rate of the stain content in this stage is small.

[0070] In this scheme, the stain content is used to indicate whether the clothes are rinsed clean. Generally, two rinsing procedures are performed, and the rinsing procedure mainly dissolves the residual detergent in the clothes in the rinsing water, and finally discharges it into the washing tub with the rinsing water. In this process, no stains on the clothes will be dissolved in the rinsing water. Therefore, the degree of rinsing is no longer indicated by the change rate of the stain content, but by the stain content. The closer the detected stain content value is to the detection value of tap water, the higher the degree of rinsing is.

[0071] It is worth noting that, in the above scheme: the determination of the stain content change rate includes the following steps:

[0072] Step S1, during the washing process of the washing device, obtaining the stain content of the washing water by a stain detection device;

[0073] Step S2, setting a preset interval time, and obtaining the stain content of the washing water again when the preset interval time is reached;

[0074] Step S3: Calculate the change rate of the stain content according to the stain contents obtained twice and the preset interval time.

[0075] In the solution provided by this embodiment, the stain detection device is used to obtain the stain content of the washing water, and then the stain detection device stops detecting. When the preset interval time is reached, the stain detection device detects the stain content in the washing water again, and the stain content change rate within the preset interval time is obtained based on the stain contents detected twice and the preset interval time. In the above solution, multiple stain contents within a period of time can be taken to calculate multiple stain content change rates, and the average value is taken, so that the stain amount change rate within the time period is more accurate.

[0076] In the solution of this embodiment, the stain detection device performs stain detection on the washing water; obtains the change rate of the stain content in the washing water according to the detection result; and the display device displays the stain-related information according to the change rate of the stain content;

[0077] And / or, in the rinsing process, the stain detection device performs stain detection on the rinsing water; obtains the stain content in the rinsing water according to the detection result; and the display device displays the stain-related information according to the stain content.

[0078] The following is a detailed description of the above scheme:

[0079] like Figure 1 As shown, during the washing process, the ultraviolet spectrum sensor detects the information related to the stains in the washing water to obtain the stain content in the washing water. Every time the preset interval time is reached, the ultraviolet spectrum sensor detects the information related to the stains in the washing water again to obtain the stain content in the washing water again. The ultraviolet spectrum sensor sends the stain content detected multiple times to the display device or the control system of the washing machine, and obtains the change rate of the stain content in the washing water through calculation and analysis. The digital tube on the display device displays the obtained value of the change rate of the stain content. The user can know the degree of cleaning of the clothes according to the value of the change rate of the stain content on the display tube.

[0080] like Figure 2 As shown, during the rinsing process, the ultraviolet spectrum sensor detects the stain-related information in the washing water to obtain the stain content in the washing water. Every time the preset interval time is reached, the ultraviolet spectrum sensor detects the stain-related information in the washing water again to obtain the stain content in the washing water again. The ultraviolet spectrum sensor sends the stain content detected multiple times to the display device. The digital tube on the display device displays the obtained stain content. The user can know the degree of rinsing of the clothes according to the stain content value on the display tube.

[0081] In the solution provided by this embodiment, during the washing or rinsing process, the user can determine the degree of cleanliness or rinsing of the clothes through the numerical value displayed on the display device, so as to make the next step response according to the washing or rinsing situation and wash or rinse the clothes cleanly.

[0082] Embodiment 2

[0083] This embodiment provides a control method for a washing machine.

[0084] The difference between this embodiment and the above-mentioned embodiments is that a dashboard for displaying the degree of washing / rinsing is provided on the display device.

[0085] In this solution, when a dashboard for displaying the degree of cleaning / rinsing is provided on the display device, the dashboard has a display area, and an indicator mark points to different display areas according to the numerical value of the detected rate of change of the stain content. The user can clearly judge the degree of cleaning or rinsing according to the position pointed by the indicator mark.

[0086] Specifically, the display device is provided with at least two display areas corresponding to different washing / rinsing degrees; the display area for controlling the washing degree according to the rate of change of the stain content is highlighted, and the display area for controlling the rinsing degree according to the stain content is highlighted.

[0087] The display device is also provided with an indicator mark for pointing to any display area to highlight it; the stain-related information is the display area pointed to by the indicator mark;

[0088] The washing equipment presets a one-to-one correspondence between the range of the change rate of the stain content and different degrees of cleaning, and the washing equipment presets a one-to-one correspondence between the range of the stain content and different degrees of rinsing;

[0089] The indicator on the display device points to the corresponding display area according to the detected stain content change rate or stain content.

[0090] Determine which group of preset soil content change rate ranges the detected soil content change rate falls into, and the indicator on the display device points to the display area corresponding to the group of preset soil content change rate ranges;

[0091] It is determined which set of preset stain content ranges the detected stain content falls into, and the indicator on the display device points to the display area corresponding to the set of preset stain content ranges.

[0092] Next, the above scheme is explained in detail:

[0093] The instrument panel on the display device is provided with three display areas corresponding to different cleaning degrees, which are a high cleaning area, a medium cleaning area, and a low cleaning area from left to right. The instrument panel is also provided with an indicator mark for pointing to any display area, and the indicator mark is used to point to any display area to highlight it. In the scheme of this embodiment, the indicator mark is a pointer. Three groups of preset stain content change rate ranges are also provided, and the three groups of preset stain content change rate ranges correspond to the high cleaning area, the medium cleaning area, and the low cleaning area, respectively.

[0094] During the washing process, the ultraviolet spectrum sensor detects the stain content in the washing water, and then sends the detected stain content to the display device, which obtains the stain content change rate and compares the stain content change rate with three groups of preset stain content change rates to determine which group of preset stain content change rates the detected stain content change rate falls into, and determines the display area corresponding to the preset stain content change rate that falls into, and the pointer points to the corresponding display area, such as the high-cleaning area, the medium-cleaning area, and the low-cleaning area. In this way, the user can judge the degree of cleanliness of the clothes according to the display area indicated by the pointer.

[0095] Similarly, the instrument panel is also provided with three display areas corresponding to different rinsing degrees, which are high rinsing area, medium rinsing area, and low rinsing area from left to right. Among them, the display areas of the rinsing degree are set one by one with the display areas of the rinsing degree. The high rinsing area is set corresponding to the high rinsing area, the medium rinsing area is set corresponding to the medium rinsing area, and the low rinsing area is set corresponding to the low rinsing area.

[0096] Three groups of preset stain content ranges are also provided, and the three groups of preset stain content ranges correspond one by one to the high rinse area, the medium rinse area, and the wash rinse area, respectively.

[0097] Similarly, during the rinsing and washing process, the ultraviolet spectrum sensor detects the stain content in the rinsing water, and then sends the detected stain content to the display device, and compares the stain content with the three groups of preset stain contents, determines which group of preset stain contents the detected stain content falls into, determines the display area corresponding to the preset stain content, and the pointer points to the corresponding display area, such as the high rinse area, the medium rinse area, and the wash rinse area. In this way, the user can judge the degree of rinsing of the clothes according to the display area indicated by the pointer.

[0098] like Figure 3 As shown, the instrument panel can also be provided with four display areas, corresponding to which there are four groups of preset stain content ranges. Multiple display areas can be provided according to actual needs. In the solution of this embodiment, the number of display areas provided is not limited.

[0099] The solution of this embodiment also includes: display areas corresponding to different washing / rinsing degrees have different display colors.

[0100] In the above scheme, different display areas are provided with different display colors. For example, the high cleaning area is red, the medium cleaning area is green, and the low cleaning area is yellow. Correspondingly, the high rinsing area is red, the medium rinsing area is green, and the low rinsing area is yellow.

[0101] In the above scheme, since different display areas have different colors, the user can intuitively observe the degree of washing or rinsing of the clothes through the display areas and their corresponding colors, thereby improving the user experience.

[0102] Embodiment 3

[0103] This embodiment provides a control method for a washing machine.

[0104] The difference between this embodiment and the second embodiment is that a progress bar for displaying the degree of washing / rinsing is provided on the display device.

[0105] The display device is provided with a progress bar for displaying the degree of washing / rinsing. Similar to the instrument panel in the above scheme, this scheme also provides different display areas, and different display areas correspond to different preset soil content change rate ranges, and the preset soil content change rate range includes a specific soil content change rate value. The indicator on the progress bar can not only indicate the display area it falls into, but also indicate the specific value in the display area.

[0106] Embodiment 4

[0107] This embodiment provides a control method for a washing machine. This solution is a further description of the above embodiment.

[0108] The solution of this embodiment includes: the washing device is preset with a washing gear / rinsing gear corresponding to different washing degrees / rinsing degrees, and the washing gear / rinsing gear respectively corresponds to a stain content change rate range and a stain content range;

[0109] Before performing the washing operation, the washing device receives a set washing gear / rinsing gear instruction;

[0110] Detecting the change rate of the stain content in the washing water and the stain content in the rinsing water, and comparing them with the stain content change rate range and the stain content range corresponding to the set wash gear / rinse gear instruction respectively;

[0111] If the set washing gear / rinsing gear is reached, the washing program / rinsing program will be controlled to stop running;

[0112] If the set wash level / rinse level is not reached after the washing program / rinsing program ends, the range of the stain content change rate detected at the end of the washing program / rinsing program and the wash level / rinse level corresponding to the stain content range will be displayed.

[0113] The following is a detailed description of the above scheme:

[0114] In this scheme, the washing device presets different washing degrees with corresponding washing gears, and different rinsing degrees with corresponding rinsing gears. Among them, the washing gear / rinsing gear respectively corresponds to the stain content change rate range and the stain content range. Before washing, the user can set the washing gear / rinsing gear. Then the washing program is executed. When the washing program is running, the gear corresponding to the washing state is determined according to the detected stain content change rate, and the current detected stain content change rate is compared with the preset stain content change rate of the set gear in real time. If the lowest preset stain content change rate value of the set gear has been reached, it means that the set washing gear has been reached, the clothes have reached the washing conditions set by the user, and the washing program ends. Then the rinsing program is executed. When the rinsing program is running, the gear corresponding to the rinsing state is determined according to the detected stain content, and the current detected stain content is compared with the preset stain content of the set gear in real time. If the lowest preset stain content value of the set gear has been reached, it means that the clothes have reached the rinsing conditions set by the user, and the rinsing program ends.

[0115] In another scheme of the present embodiment, before washing, the user can set the wash gear / rinse gear. Then execute the washing program. When the washing program is running, the gear corresponding to the washing state is determined according to the detected stain content change rate, and the currently detected stain content change rate is compared with the preset stain content change rate of the set gear in real time. If the washing reaches the maximum washing time and still does not reach the lowest preset stain content change rate value of the set gear, the current wash gear is displayed to remind the user that the washing has not been reached. Rinsing is the same as the scheme described in the above scheme. If the rinse gear is not reached after the maximum number of rinses, the current rinse gear is displayed to remind the user that the clothes are not rinsed, and the user is reminded to reduce the amount of detergent when washing again.

[0116] In the above scheme, energy can be saved on the basis of washing or rinsing.

[0117] Embodiment 5

[0118] This embodiment provides a control method for a washing machine. This solution is a further description of the second and third embodiments.

[0119] like Figure 3 As shown, in the solution of this embodiment, the instrument panel can be provided with a display area not only to display the degree of washing and rinsing, but also to display the dehydration status. The dehydration is divided into four gears, and different gears correspond to different dehydration times and dehydration speeds. The higher the gear, the higher the speed and the shorter the dehydration time.

[0123] In the above scheme, the stain detection device is an ultraviolet spectrum sensor, and the display device is provided with a dashboard, a progress bar or a digital tube for displaying the degree of cleaning / rinsing.

[0124] In this embodiment, the detection device used in the scheme is an ultraviolet spectrum sensor, which detects the stain content of washing water by ultraviolet absorption spectroscopy. The ultraviolet spectrum sensor uses ultraviolet absorption spectroscopy to detect the stain content. The ultraviolet absorption spectroscopy detects the amount of the substance by the corresponding relationship between the substance and its ultraviolet visible spectrum when the substance absorbs light of a specific wavelength to reach the maximum value. The stains include a variety of substances that cannot be detected by conventional sensors. The conventional sensors, such as infrared tube sensors, cannot detect organic soluble stains, including oily stains, proteins, laundry detergents and emulsions, while the ultraviolet spectrum sensor can detect the above-mentioned organic soluble stains and insoluble particles. Since organic soluble stains include the main types of dirt on clothes, during the washing process, by performing real-time and accurate detection of the amount of dissolution, the degree of washing or rinsing of the clothes can be more accurately displayed.
