[0025] In addition, it should be noted that in the description of the present invention, although the various steps of the control method of the present invention are described in this application in a specific order, these orders are not restrictive. Without departing from the basic principles of the present invention, those skilled in the art can perform the steps in a different order.

[0026] Based on the technical problems raised in the background technology, the present invention provides a control method for a clothing processing device, which aims to achieve an alarm prompt and long-term ventilation effect when a child or pet accidentally enters the clothing processing device and closes the door 8 when the clothing processing device is in a non-operating state, thereby avoiding suffocation due to the non-circulation of the environment in the chamber and improving safety.

[0027] See first Figure 1 , which is a schematic diagram of the structure of the clothing processing device of the present invention. Figure 1 As shown, the clothing processing device includes a housing 1, a drum assembly 2 arranged in the housing 1, a damper 4, a fan 7 and a ventilation duct 5. The housing 1 is provided with an openable and closable door 8, the drum assembly 2 is provided with a first vent 3 and a second vent 6 connected to its internal chamber, the damper 4 is arranged at the first vent 3 and is configured to enable the chamber to be connected to and blocked from the outside, the first vent 3 is also connected to the air inlet of the fan 7 through the ventilation duct 5, and the air outlet of the fan 7 is connected to the second vent 6.

[0028] Exemplarily, the damper 4 is an electric damper, including a driving device and a damper plate. The damper 4 plate is rotatably arranged at the first vent 3. The driving end of the driving device is connected to the damper plate. The damper plate is driven to rotate to realize the opening and closing of the first vent 3, so that the chamber can be connected to and blocked from the outside. It should be noted that the specific structure of the damper 4 is not limited to the structure of "driving device + damper plate" described above. As long as it can connect and block the chamber to the outside, the present invention does not impose any limitation on the specific structure of the damper 4.

[0029] Specifically, the first vent 3 is provided at the top of the barrel assembly 2, and the second vent 6 is provided at the bottom of the barrel assembly 2. The air flow path is as follows Figure 1 As shown, when the door body 8 is closed, the air flow inside the chamber can be realized when the fan 7 is running, and when the damper 4 is opened, the chamber can be connected with the outside world, and can be used in conjunction with the fan 7 to better achieve the ventilation effect between the chamber and the outside world.

[0030] See below Figure 2 , which is a flow chart of the main steps of the control method of the clothes processing device of the present invention. Figure 2 As shown, when the clothing processing device is in a non-operating state, when a living body is detected in the chamber and the door body 8 is in a closed state, the control method of the present invention includes:

[0031] S1, when a living being is detected in the chamber for a first preset time, the damper 4 is controlled to open;

[0032] S2, when the presence of a living body is detected in the chamber for a second preset time, the fan 7 is controlled to start and run;

[0033] Wherein, the first preset time is less than the second preset time.

[0034] In the above steps, illustratively, a camera (not shown in the figure) is set in the chamber to detect whether there is a life form inside it. Of course, the camera can also be set at other locations other than the chamber, or set in other forms other than the camera, as long as it can detect whether there is a life form in the chamber. The present invention does not impose any restrictions on the location and physical form of the camera.

[0035] Furthermore, the specific settings of the first preset time and the second preset time can be pre-set when the device leaves the factory, or can be set by the user as needed. For example, the first preset time is set to 30S. When the presence of a living organism is detected in the chamber for 30S, that is, the living organism has not left the chamber at this time, the damper 4 is controlled to open, so that the chamber is connected to the outside world to achieve ventilation. The second preset time is set to 120S. When the presence of a living organism is detected in the chamber for 120S, that is, the living organism has not left the chamber at this time, the fan 7 is controlled to start and run to promote air flow in the chamber, which can better achieve the effect of ventilation between the chamber and the outside world and avoid suffocation due to poor air circulation in the chamber.

[0036] The control method of the present invention further includes:

[0037] When or after the air door 4 is opened, the clothes processing device is controlled to issue an alarm.

[0038] The step of "controlling the clothing processing equipment to issue an alarm prompt" specifically includes:

[0039] Control the clothes processing equipment to give out a sound alarm prompt.

[0040] In the above steps, when the presence of a living being is detected in the chamber for a first preset time, that is, the living being has not left the chamber at this time, in addition to controlling the damper 4 to open in step S1 to ensure ventilation between the chamber and the outside, the clothing processing device is also controlled to issue an alarm prompt to prompt the user to handle it in time. Exemplarily, a buzzer can be provided in the clothing processing device to issue a buzzer sound for an alarm prompt. Of course, those skilled in the art can also use alarm prompts other than sound alarm prompts, such as SMS reminders or system reminders, and the above adjustments are all within the scope of protection of the present invention.

[0041] The control method of the present invention further includes:

[0042] After the damper 4 is opened, it is determined whether there is a living body in the chamber;

[0043] If the judgment result is "yes", the damper 4 is controlled to continue to be opened and the clothes processing device is controlled to continue to issue an alarm prompt;

[0044] If the judgment result is "no", the damper 4 is controlled to be closed and the clothes processing device cancels the alarm prompt.

[0045] In the above steps, after the damper 4 is opened, if no life is detected in the chamber after the first preset time and before the second preset time, it indicates that the life has left on its own. At this time, the damper 4 is controlled to close and the alarm prompt is released.

[0046] In another alternative specific embodiment, the control method of the present invention further includes:

[0047] After the air door 4 is opened, determining whether the alarm prompt of the clothes processing device is released;

[0048] If the judgment result is "yes", the damper 4 is controlled to be closed;

[0049] If the judgment result is "no", the damper 4 is controlled to continue to be opened and the clothes processing device is controlled to continue to issue an alarm prompt.

[0050] In the above steps, after the damper 4 is opened, if the alarm prompt of the chamber is released after the first preset time and before the second preset time, it indicates that there is human intervention to release and close the alarm prompt, and the damper 4 is controlled to be closed.

[0051] The control method of the present invention further includes:

[0052] After the fan 7 is running, it is determined whether the door 8 is opened;

[0053] If the judgment result is "yes", the damper 4 is controlled to close, the alarm prompt of the laundry processing device is released, and the fan 7 stops running;

[0054] If the judgment result is "No", execute step S2.

[0055] In the above steps, when the door 8 is opened, the interior of the chamber is connected to the outside world, so that the living environment of the living organism in the chamber can be guaranteed. At this time, the damper 4 is closed, the alarm is released, and the fan 7 stops running.

[0056] The control method of the present invention further includes:

[0057] Get the actual oxygen concentration in the chamber;

[0058] The steps of “controlling the operation of the fan 7” specifically include:

[0059] When the actual oxygen concentration is greater than or equal to the first preset oxygen concentration, the fan 7 is controlled to run at a first speed;

[0060] When the actual oxygen concentration is greater than or equal to the second preset oxygen concentration and less than the first preset oxygen concentration, the fan 7 is controlled to run at a second speed;

[0061] When the actual oxygen concentration is less than the second preset oxygen concentration, the fan 7 is controlled to run at a third speed;

[0062] The first rotation speed is less than the second rotation speed and less than the third rotation speed, and the second preset oxygen concentration is less than the first preset oxygen concentration.

[0063] In the above steps, illustratively, an oxygen concentration sensor (not shown in the figure) is provided in the chamber to detect the oxygen concentration in the chamber in real time, and transmit the real-time detected oxygen concentration to the controller, and the controller compares the actual oxygen concentration with the preset oxygen concentration to control the operating speed of the fan 7 accordingly. Of course, the oxygen concentration sensor can also be set at other locations other than the chamber, as long as it can detect the oxygen concentration in the chamber, and the present invention does not impose any restrictions on the setting position of the oxygen concentration sensor. In addition, the settings of the first speed, the second speed and the third speed, as well as the first preset oxygen concentration and the second preset oxygen concentration can be pre-set when the equipment leaves the factory, or can be set by the user as needed.

[0064] Specifically, when the actual oxygen concentration is greater than or equal to the first preset oxygen concentration, it indicates that the oxygen concentration in the chamber is in a qualified state at this time, and the fan 7 is controlled to run at a first speed, that is, to run at a low speed; when the actual oxygen concentration is greater than or equal to the second preset oxygen concentration and less than the first preset oxygen concentration, it indicates that the oxygen concentration in the chamber is low at this time, and the fan 7 is controlled to run at a second speed, that is, to run at a medium speed; when the actual oxygen concentration is less than the second preset oxygen concentration, it indicates that the oxygen concentration in the chamber is in a deficient state at this time, and the fan 7 is controlled to run at a third speed, that is, to run at a high speed, to speed up the air flow in the chamber, so as to reach the oxygen demand in a short time and avoid suffocation.

[0065] In another alternative specific embodiment, the control method of the present invention further includes:

[0066] Get the actual temperature in the chamber;

[0067] The steps of “controlling the operation of the fan 7” specifically include:

[0068] When the actual temperature is greater than or equal to the first preset temperature, the fan 7 is controlled to run at a first speed;

[0069] When the actual temperature is greater than or equal to the second preset temperature and less than the first preset temperature, the fan 7 is controlled to run at a second speed;

[0070] When the actual temperature is lower than the second preset temperature, the fan 7 is controlled to run at a third speed;

[0071] The first rotation speed is less than the second rotation speed and less than the third rotation speed, and the second preset temperature is less than the first preset temperature.

[0072] In the above steps, illustratively, a temperature sensor 9 is provided at the first vent 3 of the chamber to detect the temperature in the chamber in real time, and transmit the real-time detected temperature to the controller, and the controller compares the actual temperature with the preset temperature to control the running speed of the fan 7 accordingly. Of course, the temperature sensor 9 can also be set at other positions besides the chamber, as long as it can detect the temperature in the chamber, and the present invention does not impose any limitation on the setting position of the temperature.

[0073] Specifically, when the actual temperature is greater than or equal to the first preset temperature, the clothing processing equipment has just finished running. At this time, the temperature in the chamber is relatively high. The fan 7 is controlled to run at the third speed, that is, to run at a high speed, to speed up the air flow between the chamber and the external environment, so as to reduce the temperature in the chamber in a short time and ensure the safety of life; when the actual temperature is greater than or equal to the second preset temperature and less than the first preset temperature, it indicates that the temperature in the chamber is slightly high at this time, and the fan 7 is controlled to run at the second speed, that is, to run at a medium speed; when the actual temperature is less than the second preset temperature, it indicates that the temperature in the chamber is relatively low at this time, and the fan 7 is controlled to run at the first speed, that is, to run at a low speed, to ensure that the chamber and the external environment are connected to achieve a balance.

[0074] See below Figure 3 , a possible control process of the present invention is introduced. Figure 3 As shown, when the clothing processing device is in a non-operating state, a living body is detected in the chamber and the door body 8 is in a closed state, a possible complete process of the control method of the present invention is:

[0075] S101, when a living body is detected in the chamber for a first preset time, the damper 4 is controlled to open and the clothes processing device is controlled to issue an alarm prompt;

[0077] If yes, execute step S104;

[0078] If not, execute step S103;

[0079] S103, controlling the damper 4 to close and the clothes processing device to release the alarm prompt;

[0080] S104, controlling the damper 4 to continue to open and controlling the clothes processing device to continue to issue an alarm prompt;

[0081] S105, when the presence of a living body is detected in the chamber for a second preset time, obtaining an actual oxygen concentration in the chamber;

[0082] S106, when the actual oxygen concentration is greater than or equal to the first preset oxygen concentration, controlling the fan 7 to run at a first speed;

[0083] S107, when the actual oxygen concentration is greater than or equal to the second preset oxygen concentration and less than the first preset oxygen concentration, controlling the fan 7 to operate at a second speed;

[0084] S108, when the actual oxygen concentration is less than the second preset oxygen concentration, controlling the fan 7 to run at a third speed;

[0085] S109, determining whether the door 8 is opened;
