Description

[0002] With the advancement of science and technology and the improvement of people's living standards, high-temperature washing household appliances (such as washing machines and dishwashers) are becoming more and more popular among users due to their efficient cleaning ability and hygiene protection. High-temperature washing household appliances can quickly heat the washing liquid to a set high temperature to improve the cleaning effect. During the washing process, these devices will generate a large amount of high-temperature steam. Since the washing chamber is usually sealed, these high-temperature steam will accumulate in the chamber. Therefore, most of these household appliances will perform exhaust operations after the washing program is completed to discharge the high-temperature steam out of the chamber, thereby avoiding the high-temperature steam from causing a bad user experience and preventing the damage caused by the high-temperature steam.

[0003] However, this is limited to the final processing stage after the washing process. In actual use, if the user suddenly opens the door during the washing process and the high-temperature steam has not yet been discharged, a large amount of high-temperature steam will instantly surge out, giving the user an unpleasant experience and may even cause serious injuries such as burns.

[0041] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

When the above embodiments of this application are applied to specific products or technologies, user permission or consent is required, and the collection, use and processing of relevant data need to comply with relevant laws, regulations and standards of relevant countries and regions.

[0044] See also Figure 1 , which shows a flow chart of a control method for a washing device provided in an embodiment of the present application. It should be noted that this specification provides method operation steps such as the embodiments or flow charts, but may include more or fewer operation steps based on conventional or non-creative labor. The order of steps listed in the embodiments is only one way of executing the steps among many orders, and does not represent the only order of execution. When the system or product is executed in practice, it can be executed in the order shown in the embodiments or drawings or in parallel (for example, in a parallel processor or multi-threaded processing environment). Specifically, Figure 1 As shown, the method may include:

[0045] S101, during the operation of the washing machine, in response to a door opening instruction from a user, controlling the washing machine to pause operation.

[0046] The washing equipment refers to a cavity-type washing equipment capable of high-temperature washing, such as a washing machine, a dishwasher, etc. Specifically, the washing equipment includes a door body and a washing cavity for placing washing objects, an opening is provided on one side of the washing cavity, and the door body is provided on the side of the opening for opening or closing the washing cavity.

[0047] Specifically, when the washing equipment receives a door opening command from the user during operation, the control system responds immediately and sends a signal to suspend the equipment, ensuring that the equipment is in a stationary state before conducting subsequent safety checks to reduce potential risks.

[0048] In specific implementation, the user can trigger the door opening command through the door handle, physical button, touch screen, voice control, etc. on the washing device. Specifically, the user holds the door handle and gently pulls it outward, and this action triggers the switch or sensor on the door handle; a sensor (such as a mechanical switch, pressure sensor, proximity sensor, etc.) is installed inside or near the door handle to detect the user's door pulling action, and the sensor transmits the detected action signal to the control system.

[0049] S103, obtaining current steam information in the washing chamber.

[0050] Among them, the current steam information refers to data reflecting the state of steam in the washing cavity, which may include parameters such as steam concentration and temperature.

[0051] In specific implementation, the steam state in the washing cavity can be detected in real time through built-in sensors (such as temperature sensors, humidity sensors, etc.) to obtain current steam information. These sensors can accurately measure parameters such as steam concentration and temperature in the cavity, providing a basis for subsequent decision-making.

[0052] S105, determining whether the steam state in the washing cavity indicated by the current steam information meets the preset safety standard.

[0053] Specifically, if the result of the judgment is no, step S107 can be executed; otherwise, if the result of the judgment is yes, step S109 can be executed.

[0054] Among them, the steam state refers to the various physical properties of the steam in the washing cavity, which may include the steam concentration. High concentration of steam means more moisture and heat accumulate in the washing cavity; it may also include the temperature of the steam. High-temperature steam has higher energy and may cause burns to the user; it may also include the air pressure in the washing cavity. A high-pressure environment may cause steam to gush out rapidly, increasing safety hazards.

[0055] Among them, the preset safety standards are used to ensure that users will not be harmed by high-temperature steam when opening the door. Specifically, the preset safety standards can be set through a variety of channels, including experimental tests, industry standards, user feedback, etc. In specific implementations, the preliminary safety standards can be determined through experimental tests, and then verified and optimized in combination with thermodynamic and fluid mechanics calculations. Specifically, various usage scenarios are simulated in a controlled environment to test the effects on users under different steam states. For example, through human models or volunteer tests, the reactions under different steam concentrations and temperatures are recorded to determine the preliminary safety range. Thermodynamic principles are used to calculate the heat transfer and energy distribution under different steam states. Through computer simulation, the flow and distribution of steam in the cavity are predicted, and the preliminary safety range is verified and optimized to obtain the preset safety standard.

[0056] Specifically, if the current steam information obtained shows that the steam state in the washing cavity does not meet the preset safety standards (for example, the steam concentration exceeds the set threshold), the control system will start the steam removal program, such as turning on the exhaust fan to accelerate air circulation, or quickly reduce the steam concentration in the cavity by other means (such as spraying cold air). If the current steam information obtained shows that the steam state in the washing cavity does not meet the preset safety standards, the control system will control the door to open the washing cavity.

[0057] In an exemplary embodiment, the washing device further includes an image acquisition device disposed in the washing cavity; the current steam information includes a cavity state image acquired by the image acquisition device, and the preset safety standard includes that the amount of steam in the washing cavity is less than a preset steam amount threshold; the above step S105 may include the following steps:

[0058] determining a current amount of steam in the washing cavity based on the cavity state image;

[0059] Determine whether the current steam volume is less than the preset steam volume threshold.

[0060] The image acquisition device refers to a camera or other imaging device installed inside the washing device, which is used to capture images inside the washing cavity. Specifically, the image acquisition device is installed at a suitable position inside the washing cavity to ensure that the state inside the washing cavity can be clearly captured. In a specific implementation, when the user triggers the door opening command, the image acquisition device starts immediately to capture the cavity state image. The image acquisition frequency can be adjusted as needed, usually multiple frames per second, to ensure the real-time and accuracy of the data.

[0061] The cavity state image refers to a real-time image of the inside of the washing cavity taken by the image acquisition device, which reflects the current state of the cavity, including information such as steam volume and temperature. Specifically, the cavity state image is transmitted to the control system through the internal communication module, and the control system uses image processing algorithms (such as edge detection, grayscale analysis, pixel density calculation, etc.) to analyze the image and extract the current steam volume information. For example, the steam volume can be estimated by analyzing the pixel density of the steam area in the image.

[0062] The current steam volume is steam volume information extracted from the cavity state image by image analysis technology. Specifically, the current steam volume can be calculated by using parameters such as pixel density and grayscale value obtained from the cavity state image, or directly represented by parameters such as pixel density and grayscale value.

[0063] Specifically, use filtering algorithms (such as Gaussian filtering and median filtering) to remove noise in the cavity state image and improve image quality; convert color images into grayscale images to simplify subsequent processing steps; normalize the grayscale value of the image to the range of 0-255 for subsequent analysis. Use edge detection algorithms (such as Canny and Sobel) to detect edges in the image and distinguish steam areas from other areas; use threshold segmentation methods (such as Otsu algorithm) to divide the image into foreground (steam area) and background (non-steam area); use morphological operations such as expansion and corrosion to remove small noise areas and retain the main steam area. Calculate the pixel density of the steam area, that is, the proportion of the number of pixels in the steam area to the total number of pixels; analyze the average grayscale value of the steam area, and a higher grayscale value indicates more steam; calculate the area of ​​the steam area, and the larger the area, the more steam it means. Combine indicators such as pixel density, grayscale value and area to calculate the current steam volume. For example, a weighted average method can be used.

[0064] The preset steam volume threshold refers to the upper limit of the steam volume, which is used to determine whether the steam volume in the cavity reaches the safety standard. In specific implementations, the preset steam volume threshold is usually set according to safety standards and experimental tests.

[0065] Specifically, if the current steam volume is less than the preset steam volume threshold, it is considered that the steam state in the cavity meets the safety standards and the door can be opened safely; if the current steam volume is greater than or equal to the preset steam volume threshold, the steam removal program is started until the steam volume drops to a safe range.

[0066] It can be seen from the above technical solutions of the embodiment of the present application that the embodiment of the present application monitors the steam state in the washing cavity in real time through the image acquisition device and image processing technology, and determines whether the current steam volume meets the safety standards, thereby ensuring that the user will not be harmed by high-temperature steam when opening the door at any time, thereby significantly enhancing the safety performance of the washing equipment.

[0067] In an exemplary embodiment, the washing device further includes an audio prompt device; when the result of the judgment in the above step S105 is no, the method may further include the following steps:

[0068] Determine whether the audio prompt instruction corresponding to the door opening instruction has been executed; the audio prompt instruction includes a first prompt instruction, and the first prompt instruction is used to prompt the user to temporarily lock the washing cavity;

[0069] When the audio prompt instruction corresponding to the door opening instruction has not been executed, the audio prompt device is controlled to execute the first prompt instruction.

[0070] The audio prompt device refers to a speaker or other sound-generating device installed on the washing equipment, which is used to issue sound prompts to the user.

[0071] Specifically, checking whether the audio prompt instruction corresponding to the current door opening instruction has been executed can be achieved through a flag bit or a state variable. For example, a Boolean variable audioPromptExecuted is set with an initial value of false, indicating that the audio prompt instruction has not been executed. If audioPromptExecuted is false, it means that the audio prompt instruction has not been executed, and the audio prompt device is controlled to execute the first prompt instruction. After executing the first prompt instruction, audioPromptExecuted is set to true, indicating that the audio prompt instruction has been executed. This can avoid hearing the same prompt tone multiple times while the user is waiting, thereby improving the user experience.

[0072] Specifically, during the steam removal process, the current steam information is continuously monitored and updated to ensure that the steam state gradually returns to a safe range. In the subsequent monitoring of the steam state in the washing chamber, if it is detected again that the steam state does not meet the safety standard, the first prompt instruction will not be executed again because audioPromptExecuted is already true.

[0073] Specifically, the first prompt instruction is used to prompt the user that the washing cavity is temporarily locked and the door cannot be opened immediately. For example, the audio prompt device plays a voice message "high temperature steam will hurt people, do not open the door".

[0074] It can be seen from the above technical solutions of the embodiment of the present application that the embodiment of the present application improves the user's operational convenience and safety by sending a clear prompt to the user through the audio prompt device when the current steam state does not meet the safety standards, informing the user that the washing cavity is temporarily locked and the door cannot be opened immediately. By judging whether the audio prompt instruction corresponding to the door opening instruction has been executed, it is ensured that the first prompt instruction is only executed once under the current door opening instruction, avoiding repeated execution in the subsequent monitoring process, reducing the user's troubles and improving the user experience.

[0075] S107, performing steam cleaning treatment on the washing cavity.

[0076] Specifically, return to step S103.

[0077] Specifically, during the steam removal process, the control system continuously monitors and updates the steam information to ensure that the steam state gradually returns to a safe range. Once the updated steam information indicates that the steam state in the chamber meets the preset safety standards, the control system will stop the steam removal process.

[0078] Specifically, the steam state parameters that exceed the preset safety standards are determined, and the corresponding steam removal program is started. Specifically, if the steam concentration exceeds the preset safety standard, the exhaust fan can be started, the exhaust fan speed can be increased, and the discharge of steam in the cavity can be accelerated; the steam concentration in the cavity can also be reduced by spraying cold air to promote steam condensation and discharge. If the steam temperature exceeds the preset safety standard, the cooling system can be started to reduce the temperature in the cavity by circulating cold water or cold air; the temperature in the cavity can also be directly reduced by spraying cold air. If the steam pressure exceeds the preset safety standard, the pressure relief valve can be opened to quickly reduce the pressure in the cavity; the exhaust fan can also be started and the exhaust fan speed can be increased to help quickly discharge the gas in the cavity and reduce the pressure.

[0079] In an exemplary embodiment, the washing device further includes a drainage device, a water supply device, a spray device, and an exhaust device respectively disposed in the washing cavity; the above step S107 may further include the following steps:

[0080] Control the drainage device to drain the water in the washing chamber;

[0081] Controlling the water inlet device to add water into the washing chamber according to a preset water volume, so that the heat carried by the steam in the washing chamber is transferred to the water in the washing chamber;

[0082] Accordingly, the above step S107 may include: during the heat transfer process, controlling the spraying device to spray into the washing cavity, and controlling the exhaust device to exhaust the washing cavity.

[0083] Specifically, when the current steam information indicates that the steam state in the washing cavity does not meet the preset safety standards, the water device, the water supply device, the spray device, and the exhaust device are turned on in sequence to perform steam removal processing. In the subsequent monitoring of the steam state in the washing cavity, the spray device and the exhaust device are kept working until the steam state in the washing cavity meets the preset safety standards.

[0084] Among them, the drainage device is a device installed at the bottom of the washing cavity, which is used to drain the water in the cavity.

[0085] Among them, the water supply device is a device for adding water to the washing cavity, usually including a water pump and a water pipe. Specifically, since step S101 has controlled the washing equipment to suspend operation, including the heating element of the washing equipment, the water added to the washing cavity by the water supply device is cold water at this time, and the heat carried by the high-temperature steam will be transferred to the cold water. This is due to the second law of thermodynamics that heat naturally flows from the high-temperature area to the low-temperature area. As the heat is transferred, the steam begins to condense into liquid water, and a large amount of latent heat is released in this process. The release of this latent heat is an efficient form of energy transfer, which allows the steam to quickly lose heat and convert into liquid.

[0086] The spray device is installed in the washing cavity to spray water into the cavity to help cool and remove steam. Specifically, the water mist generated by the cold water spray can promote air flow, form forced convection, enhance heat exchange efficiency, and make heat transfer faster.

[0087] Among them, the exhaust device is a device installed on the top or side of the washing cavity, which is used to discharge the steam in the cavity.

[0088] The preset water volume is usually the amount of water added according to experimental tests to effectively absorb the heat in the steam. The preset water volume should be selected to ensure that the heat in the steam can be effectively absorbed without increasing the water level in the cavity too much.

[0089] Specifically, when the control system detects that the current steam state does not meet the preset safety standards, the drainage device is controlled to drain the water in the washing cavity. After the drainage is completed, the water supply device is controlled to add water to the washing cavity according to the preset water volume. After the water is added, the spray device is started to spray water into the washing cavity. The water mist generated by the spray can promote air flow, form forced convection, enhance heat exchange efficiency, and make heat transfer faster. At the same time, the exhaust device is started to discharge the steam and air in the washing cavity. The activation of the exhaust device helps to reduce the pressure in the cavity and promote the rapid discharge of steam.

[0090] It can be seen from the above technical solutions of the embodiment of the present application that the embodiment of the present application automatically starts the steam removal process when it is detected that the steam state in the washing cavity does not meet the preset safety standards. Through the comprehensive measures of drainage, water addition, spraying and exhaust, the high-temperature steam in the cavity is quickly and effectively removed to ensure that the steam state in the cavity meets the safety standards. The efficient heat transfer and heat exchange process makes the steam removal process more energy-saving and efficient.

[0091] In an exemplary embodiment, after executing step S107, if the result of step S105 is yes, the steam removal process is stopped, which may specifically include the following steps:

[0092] Control the sprinkler device to stop working, and control the exhaust device to stop working;

[0093] Control the drainage device to drain the water in the washing chamber.

[0094] Specifically, when it is detected that the steam state in the washing cavity has returned to the preset safety standard, the spray device is controlled to stop working and stop spraying water mist; at the same time, the exhaust device is controlled to stop working and stop exhaust operation. After the above is completed, the drainage device is controlled to drain the water in the washing cavity to ensure that there is no residual water in the washing cavity, ready for the user to open the door.

[0095] It can be seen from the above technical solutions of the embodiment of the present application that the embodiment of the present application stops the steam removal process after the steam state returns to the safety standard and ensures that there is no residual water in the cavity, thereby preparing for the user to open the door. This not only improves the user's operating convenience and usage experience, but also significantly enhances the safety performance of the washing equipment.

[0096] S109, controlling the door to open the washing chamber.

[0097] Specifically, after confirming that the steam state in the washing cavity has reached a preset safety standard, the door is controlled to open, allowing the user to access the interior of the washing cavity.

[0098] It can be seen from the above technical scheme of the embodiment of the present application that the embodiment of the present application controls the washing device to pause its operation according to the user's door opening command during the operation of the washing device, obtains the current steam information in the washing cavity, and when the current steam information indicates that the steam state in the washing cavity does not meet the preset safety standards, performs steam clearing processing on the washing cavity, updates the current steam information, and opens the door only when the updated current steam information indicates that the steam state in the washing cavity meets the preset safety standards, thereby effectively preventing the user from being scalded by high-temperature steam due to opening the door during the operation of the washing device, thereby ensuring the user's safety and experience.

[0099] In an exemplary embodiment, the audio prompt instruction further includes a second prompt instruction, and the second prompt instruction is used to prompt the user to unlock the washing cavity; the above step S1011 may include the following steps:

[0100] Controlling the audio prompt device to execute a second prompt instruction so that the user can confirm whether to execute the door opening instruction;

[0101] When the user confirms the door opening instruction, the door is controlled to open the washing chamber.

[0102] Specifically, the audio prompt device is controlled to execute the second prompt instruction to inform the user that the washing cavity has been unlocked and the door can be opened safely. For example, the audio prompt device plays the voice "The washing cavity has been unlocked and the door can be opened safely." After hearing the second prompt instruction, the user can choose whether to execute the door opening instruction. The user can confirm the execution of the door opening instruction by triggering the door opening instruction again (such as pulling the door handle, pressing a button, voice, etc.). When the user confirms the execution of the door opening instruction, the door body is controlled to open, allowing the user to access the inside of the washing cavity.

[0103] In specific implementation, if the user chooses not to open the door, the control system will resume the operation of the washing device. If the user does not respond within a certain period of time (such as 30 seconds), it is assumed that the user chooses not to open the door, and the control system will resume the operation of the washing device.

[0104] It can be seen from the above technical solutions of the embodiment of the present application that the embodiment of the present application improves the user's operational convenience and safety by informing the user again through the audio prompt device that the washing cavity has been unlocked and the door can be opened safely after the steam state has returned to the safety standard. After the washing cavity is unlocked, the user is informed through the audio prompt device and asked to confirm whether to execute the door opening command. This double confirmation mechanism further improves the safety of the system and the user's experience.

[0105] In order to facilitate a full understanding of the solution of this application, the following is a summary of the process of opening the door for the user during the operation of the washing machine. Figure 2 , which is a flow chart of another control method for washing equipment provided by an embodiment of the present application, which may specifically include:

[0106] (1) The internal conditions of the dishwasher cavity are monitored by a camera. If high-temperature steam is detected, a rapid cooling and steam removal program is initiated;

[0107] (2) The drainage device discharges the water in the washing chamber;

[0108] (3) The water supply device adds cold water into the washing chamber;

[0109] (4) The spray device sprays cold water into the washing chamber, and the exhaust device exhausts the washing chamber;

[0110] (5) judging whether there is steam in the washing chamber according to the monitoring result of the camera;

[0111] Specifically, if there is steam, return to step (4) to continue the cold water spraying and exhaust operation; if there is no steam, proceed to the next step;

[0112] (6) Turn off the sprinkler and exhaust devices, and prompt the user to open the door through voice;
