Technical Field

The present invention relates to the technical field of equipment control, and in particular to a control method and device for cleaning equipment, cleaning equipment and a storage medium.

Background Art

As people's living standards improve, the market demand for dishwashers is growing. The use of dishwashers has brought great convenience to people's lives and can achieve the integrated washing, disinfection, drying and storage of tableware.

Currently, dishwashers on the market all have washing and drying functions, but the washing or drying methods and logic of most dishwashers are relatively fixed. Most of them run for a fixed time and then use hot air to dry. They cannot be dynamically adjusted according to the actual situation of the dishes in the dishwasher. When the number of dishes washed by the user is small, if the fixed washing logic is followed, it will lead to excessive washing time and increased energy consumption. In addition, as the drying progresses, the water droplets attached to the dishes gradually disappear. If the drying logic is not adjusted, it will take too long and increase power consumption, which is not conducive to energy saving and environmental protection.

DETAILED DESCRIPTION

In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

As people's living standards improve, the market demand for dishwashers is growing. The use of dishwashers has brought great convenience to people's lives, and can achieve the integration of washing, disinfecting, drying and storing tableware. Currently, all dishwashers on the market have a drying function, but the drying methods and logic of most dishwashers are relatively fixed. Most of them start the fan to run for a fixed time and use hot air for drying. It is impossible to dynamically adjust according to the actual situation of the tableware in the dishwasher. This method has the following shortcomings:

1) The washing logic cannot be adjusted according to the number and size of dishes. When the user washes a small number of dishes, following the fixed washing logic will result in excessive washing time and increased energy consumption;

2) It is impossible to adjust the drying time and temperature in real time according to the degree of dryness of the tableware. As the drying progresses, the water droplets attached to the tableware gradually disappear. If the drying logic is not adjusted, the drying time will be too long, the power consumption will increase, and it is not conducive to energy saving and environmental protection.

Therefore, an embodiment of the present invention provides a control method for a cleaning device, which adjusts the cleaning logic of the cleaning device according to the number and size of tableware to achieve the effect of reducing energy consumption.

According to an embodiment of the present invention, an embodiment of a control method for a cleaning device is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.

In this embodiment, a control method for a cleaning device is provided, which can be used for a cleaning device for cleaning tableware, such as a dishwasher, etc. FIG. 1 is a flow chart of a control method for a cleaning device according to an embodiment of the present invention. As shown in FIG. 1 , the process includes the following steps:

Step S101, obtaining a first thermal image corresponding to the tableware in the cleaning device before cleaning, and obtaining the specifications of the tableware according to the first thermal image.

Specifically, an infrared thermal imaging sensor can be installed in the inner tank of the cleaning device. When the cleaning device starts running, the infrared thermal imaging sensor installed in the inner tank is started to generate a corresponding first thermal image. The cleaning device controller receives the first thermal image to obtain the tableware specifications. By way of example, the tableware specifications mainly include the number of tableware and the size of the tableware.

Specifically, in thermal images, areas with higher temperatures usually appear as bright or warm colors. These areas may correspond to target objects (i.e., tableware). Therefore, the tableware and the number of tableware in the thermal image can be identified by determining the color tones corresponding to the tableware materials, such as ceramic, plastic, and stainless steel.

In some optional embodiments, before determining the number and size of tableware according to the first thermal image, it is necessary to first obtain specific parameters of the infrared thermal imaging sensor, such as the instantaneous field of view (IFOV) or the minimum focusing distance, and determine the size of the tableware according to the ratio between the pixel size of the tableware in the first thermal image and the IFOV. In addition, the size of the tableware corresponding to each tableware can be calculated in combination with the number of tableware.

Step S102, determining a target cleaning program based on the tableware specifications, and controlling the cleaning device to clean the tableware according to the target cleaning program.

Specifically, the corresponding preset target cleaning program is automatically selected according to the number and size of tableware. The target cleaning program can control the cleaning parameters in different stages (washing stage, hot rinsing stage and drying stage) to facilitate precise regulation and dynamic adjustment of the cleaning logic of the cleaning equipment.

Step S103, obtaining a second thermal image corresponding to the tableware when being washed.

Specifically, during the cleaning process, especially during the drying process, the infrared thermal imaging sensor will display the second thermal image during cleaning at regular intervals to determine whether the drying stage can be completed.

Step S104, after determining that the dishes are cleaned according to the second thermal image, turning off the cleaning device.

Specifically, the dryness of the dishes can be determined based on the second thermal image. If the dryness reaches a certain level, the dishwashing can be terminated and the cleaning equipment can be turned off to achieve the effect of reducing energy consumption.

The control method of the cleaning device provided in the present embodiment identifies the specifications of the tableware according to the first thermal image corresponding to the tableware in the cleaning device before cleaning, so as to determine the target cleaning program corresponding to the specifications of the tableware, accurately regulate and dynamically adjust the cleaning logic of the cleaning device, and shut down the cleaning device after determining that the cleaning of the tableware is completed through the second thermal image corresponding to the tableware during cleaning, thereby achieving the effect of reducing energy consumption and improving the user experience.

In this embodiment, a control method for a cleaning device is provided, which can be used for a cleaning device for cleaning tableware, such as a dishwasher, etc. FIG. 2 is a flow chart of a control method for a cleaning device according to an embodiment of the present invention. As shown in FIG. 2 , the process includes the following steps:

Step S201, obtaining a first thermal image corresponding to the tableware in the cleaning device before cleaning, and obtaining the tableware specifications according to the first thermal image. For details, please refer to step S101 of the embodiment shown in FIG1 , which will not be described in detail here.

Step S202, determining a target cleaning program based on the tableware specifications, and controlling the cleaning device to clean the tableware according to the target cleaning program.

Specifically, the tableware specifications include the number of tableware and the size of the tableware. The above step S202 includes:

Step S2021, based on the number and size of tableware, determine the target cleaning programs corresponding to the washing stage, hot rinsing stage and drying stage of the cleaning equipment respectively.

Step a1, determining a plurality of washing programs matching the number of dishes in a preset program library; wherein each washing program corresponds to a different cleaning area, washing time, washing temperature, washing water pressure, water consumption and power consumption.

Step a2, obtaining a total tableware washing area according to the size of the tableware, and determining a target washing program based on the total tableware washing area and the washing area corresponding to each washing program.

For example, when the number of tableware is n, the corresponding number of tableware sets n*x can be calculated according to a certain ratio x, and the corresponding washing program (Program A, Program B, Program C, Program D, Program E) is selected in the preset program library according to the number of tableware sets. Then, the size of the tableware is determined, and the total tableware washing area m is calculated and compared with the washing area corresponding to each washing program. The ranges of the washing areas corresponding to Program A, Program B, Program C, Program D, and Program E are respectively expressed as (a, b), (b, c), (c, d), (d, e), and (e, f), where a<b<c<d<e<f. If m is between a and b, select Program A; if it is between b and c, select Program B; if it is between c and d, select Program C; if it is between d and e, select Program D; if it is between e and f, select Program E.

The target washing program can be determined by the number and size of tableware, so that the washing time, washing temperature or washing water pressure of the cleaning equipment can be accurately controlled during washing, and washing can be stopped in time when there are too few dishes, thereby reducing energy consumption.

In some optional embodiments, the target cleaning program includes a target hot rinsing program, and the above step S2021 further includes:

Step b1, determining a plurality of hot rinsing programs matching the number of dishes in a preset program library; wherein each hot rinsing program corresponds to a different cleaning area, hot rinsing time, hot rinsing temperature, hot rinsing water pressure and rinsing agent dosage.

Step b2, obtaining the total tableware washing area according to the size of the tableware, and determining the target hot rinsing program based on the total tableware washing area and the cleaning area corresponding to each hot rinsing program.

Specifically, the target hot rinsing program can be determined according to the number and size of tableware by referring to the example of steps a1 to a2, so as to accurately control parameters such as the hot rinsing time, hot rinsing temperature, hot rinsing water pressure and amount of rinsing agent of the cleaning equipment during hot rinsing. This allows the hot rinsing to be stopped in time when there are too few dishes, thereby reducing energy consumption, reducing the amount of rinsing agent used, reducing costs and improving user experience.

In some optional embodiments, the target cleaning program includes a target drying program, and the above step S2021 further includes:

Step c1, determining a plurality of drying programs matching the number of dishes in a preset program library; wherein each drying program corresponds to a different cleaning area, fan speed and drying temperature.

Step c2, obtaining the total tableware washing area according to the size of the tableware, and determining the target drying program based on the total tableware washing area and the washing area corresponding to each hot rinsing program.

Specifically, the target drying program can be determined according to the number and size of tableware by referring to the example of steps a1 to a2, so as to accurately control parameters such as the fan speed and drying temperature of the cleaning equipment during drying, and to stop drying in time when there are too few dishes, thereby reducing energy consumption.

Step S2022, according to the target cleaning program, control the cleaning equipment to wash, hot rinse and dry the dishes in sequence.

Specifically, according to the determined target washing program, target hot rinsing program and target drying program, the dishwashing, hot rinsing and drying processes are precisely regulated in turn, which is more in line with the number and size of the dishes, thereby reducing equipment energy consumption and user costs.

Step S203, obtaining a second thermal image corresponding to the tableware when it is washed. Please refer to step S103 of the embodiment shown in FIG1 for details, which will not be described again.

Step S204: after determining that the dishwashing is complete according to the second thermal image, the cleaning device is turned off. For details, please refer to step S104 of the embodiment shown in FIG. 1 , which will not be described in detail here.

The control method of the cleaning device provided in the present embodiment identifies the number and size of the tableware in the cleaning device based on the first thermal image corresponding to the tableware in the cleaning device before cleaning, so as to determine the target washing program, target hot rinsing program and target drying program corresponding to the number and size of the tableware, and accurately regulates and dynamically adjusts the washing, hot rinsing and drying logic of the cleaning device. After determining that the cleaning of the tableware is completed through the second thermal image corresponding to the tableware during cleaning, the cleaning device is turned off, thereby achieving the effect of reducing energy consumption and improving the user experience.

In this embodiment, a control method for a cleaning device is provided, which can be used for a cleaning device for cleaning tableware, such as a dishwasher, etc. FIG. 3 is a flow chart of a control method for a cleaning device according to an embodiment of the present invention. As shown in FIG. 3 , the process includes the following steps:

Step S301, obtaining a first thermal image corresponding to the tableware in the cleaning device before cleaning, and obtaining the tableware specifications according to the first thermal image. For details, please refer to step S201 of the embodiment shown in FIG2, which will not be described in detail here.

Step S302, determining a target cleaning procedure based on the tableware specifications, and controlling the cleaning device to clean the tableware according to the target cleaning procedure. For details, please refer to step S202 of the embodiment shown in FIG. 2, which will not be described in detail here.

Step S303, obtaining a second thermal image corresponding to the tableware when it is washed. Please refer to step S203 of the embodiment shown in FIG2 for details, which will not be described in detail here.

Step S304: determining the degree of dryness of the dishes for characterizing the uniformity of temperature distribution according to the second thermal image.

Specifically, the controller of the cleaning equipment determines whether the temperature distribution on the surface of the tableware is uniform through the second thermal image. When there is residual water on the tableware, the temperature distribution on the surface of the tableware is uneven in the thermal image, and the temperature is inconsistent at different places on the tableware. The temperature is lower where there is residual water, thereby being able to determine whether the tableware is completely dry.

Exemplarily, the second thermal image at this time may be compared with the thermal image after the tableware is completely dried to obtain the degree of dryness of the tableware at this time.

For example, the uniformity of temperature distribution can also be judged according to the number of tones corresponding to the tableware area in the second thermal image. When the temperature distribution is uniform, the tableware is dry at a high level, the tones corresponding to the tableware area are relatively simple, and the number of tones is less than the preset number of tones; when the temperature distribution is not uniform, the tableware is dry at a low level, the tones corresponding to the tableware area are relatively complex, and the number of tones is greater than the preset number of tones.

Step S305, determining whether the tableware dryness is greater than a preset tableware dryness.

Specifically, if the tableware dryness is not greater than the preset tableware dryness, step S306 is executed; if the tableware dryness is greater than the preset tableware dryness, step S307 is executed.

Step S306, adjusting the current fan speed and the current drying temperature.

Specifically, the temperature distribution on the surface of the tableware is uneven, and there are water droplets on the surface of the tableware. Then adjust the corresponding speed and temperature of the fan. After that, continue drying. The infrared thermal imaging sensor continues to collect thermal images after a certain period of time and sends them to the controller for judgment until there are no water droplets on the surface of the tableware and the drying is completed.

Step S307, determining that the dishes are washed.

Specifically, the temperature of the tableware surface is evenly distributed, no water droplets remain on the tableware surface, the fan is turned off, the drying is completed, and the tableware is cleaned.

The dryness of the dishes can be obtained through the second thermal image to determine whether the dishes have been cleaned, so that the cleaning device can be turned off in time.

Step S308, after determining that the dishes are washed according to the second thermal image, the cleaning device is turned off. For details, please refer to step S204 of the embodiment shown in FIG2 , which will not be described in detail here.

The control method of the cleaning device provided in the present embodiment identifies the number and size of the tableware in the cleaning device based on the first thermal image corresponding to the tableware in the cleaning device before cleaning, so as to determine the target washing program, target thermal rinsing program and target drying program corresponding to the number and size of the tableware, and accurately regulates and dynamically adjusts the washing, thermal rinsing and drying logic of the cleaning device, and determines whether the cleaning can be ended by obtaining the degree of dryness of the tableware through the second thermal image corresponding to the tableware when cleaning. After determining that the cleaning of the tableware is completed, the cleaning device is turned off, thereby achieving the effect of reducing energy consumption and improving the user experience.

In this embodiment, a control method for a cleaning device is provided, which can be used for a cleaning device for cleaning tableware, such as a dishwasher, etc. FIG. 4 is a flow chart of a control method for a cleaning device according to an embodiment of the present invention. As shown in FIG. 4 , the process includes the following steps:

Step S401, obtaining a first thermal image corresponding to the tableware in the cleaning device before cleaning, and obtaining the tableware specifications according to the first thermal image. For details, please refer to step S301 of the embodiment shown in FIG3, which will not be described in detail here.

Step S402, determining a target cleaning procedure based on the tableware specifications, and controlling the cleaning device to clean the tableware according to the target cleaning procedure. For details, please refer to step S302 of the embodiment shown in FIG3 , which will not be described in detail here.

Step S403, obtaining a second thermal image corresponding to the tableware when it is washed. Please refer to step S303 of the embodiment shown in FIG3 for details, which will not be described again.

Step S404: Calculate the total area of residual water stains on the tableware according to the second thermal image.

Specifically, one or more thresholds can be set to separate the temperature difference area (i.e., water droplets) in the second thermal image from the background, thereby achieving the segmentation of the residual water stains and the background to obtain the residual water stain area. The residual water stain area can then be denoised, refined, and grayscaled to obtain a binary image of the residual water stain area (i.e., an image with only black and white pixels, in which the water droplet area is white), and then the total area of the residual water stain is calculated based on the area corresponding to each pixel.

Step S405, determining whether the total residual water stain area is smaller than a preset total residual water stain area.

Specifically, if the total residual water stain area is not less than the preset total residual water stain area, step S406 is executed; if the total residual water stain area is less than the preset total residual water stain area, step S407 is executed.

The total area of residual water stains can be calculated through the second thermal image to determine whether the tableware has been cleaned, so that the cleaning equipment can be turned off in time.

Step S406, adjusting the current fan speed and the current drying temperature. Please refer to step S306 of the embodiment shown in FIG3 for details, which will not be described in detail here.

Step S407, determining that the dishwashing is complete. For details, please refer to step S307 of the embodiment shown in FIG. 3, which will not be described in detail here.

Step S408: After determining that the dishwashing is complete according to the second thermal image, the cleaning device is turned off. Please refer to step S308 of the embodiment shown in FIG. 3 for details, which will not be described in detail here.

The control method of the cleaning device provided in the present embodiment identifies the number and size of the tableware in the cleaning device based on the first thermal image corresponding to the tableware in the cleaning device before cleaning, so as to determine the target washing program, target hot rinsing program and target drying program corresponding to the number and size of the tableware, accurately regulate and dynamically adjust the washing, hot rinsing and drying logic of the cleaning device, and calculates the total area of residual water stains through the second thermal image corresponding to the tableware when cleaning to determine whether the cleaning can be ended. After determining that the tableware cleaning is completed, the cleaning device is turned off to achieve the effect of reducing energy consumption and improving the user experience.

The control method of the cleaning device of the present invention is described in detail below with reference to a specific application example.

This application example uses an infrared thermal imaging sensor to generate corresponding thermal images to determine the number, size and dryness of tableware, and dynamically adjust the washing, hot rinsing and drying logic of the dishwasher.

As shown in FIG. 5 , when the dishwasher starts running, the infrared thermal imaging sensor installed in the inner tank is started to generate a corresponding first thermal image, and the controller receives the first thermal image to determine the number and size of the tableware.

It automatically selects the preset target washing program according to the number and size of dishes, and can control the washing time, washing temperature, washing water pressure, water consumption and power consumption during the washing stage to achieve energy and power saving effects.

When the dishwasher starts to enter the hot rinse stage, the amount of rinse agent and the target hot rinse program of the hot rinse stage are automatically selected according to the current number and size of dishes, so as to realize the control of the washing logic of the hot rinse stage. It should be noted that the cleaning parameters required for the washing stage and the hot rinse stage can be integrated through one washing program, that is, the time to start the hot rinse and the amount of rinse agent can be specified in the washing program.

After the hot rinsing stage, the dishwasher enters the drying stage, and controls the fan speed and drying temperature to the preset values of the target drying program based on the number and size of dishes obtained at the beginning.

Then the infrared thermal imaging sensor displays a second thermal image at regular intervals. The controller uses the second thermal image to determine whether the temperature distribution on the tableware surface is uniform. By comparing the thermal image at this time with the thermal image after the tableware is completely dried, the controller can determine how dry the tableware is at this time. When there is residual water on the tableware, the temperature distribution of the thermal image on the tableware surface is uneven, and the temperature at different places on the tableware is inconsistent. The temperature at the place with residual water is lower, so it can be determined whether the tableware is completely dry.

If the judgment result is yes, it means that the temperature distribution on the surface of the tableware is uniform, and there are no water droplets remaining on the surface of the tableware. The fan is turned off and the drying is completed.

If the judgment result is no, it means that the surface temperature distribution of the tableware is uneven and there are water droplets on the surface of the tableware. Then adjust the fan speed and drying temperature. After that, continue drying. The infrared thermal imaging sensor continues to collect and display thermal images after a certain period of time, and then passes them to the controller for judgment until there are no water droplets left on the surface of the tableware. In this way, the degree of dryness of the tableware can be monitored in real time and the drying process can be adjusted dynamically.

The embodiment of the present invention generates a corresponding thermal image through an infrared thermal imaging sensor to determine the number and size of tableware to control the cleaning logic. The thermal image is used to determine whether the surface temperature distribution of the tableware is uniform. When there is residual water on the tableware, the thermal image shows that the surface temperature distribution of the tableware is uneven and the temperature of the tableware is inconsistent. This determines whether the tableware is completely dry, and can detect the dryness of the tableware in real time and adjust the drying process.
