[0002] In modern society, garment care devices have become essential household appliances. With the development of technology, the functions of garment care devices have become increasingly complex, leading to the emergence of washer-dryer combos. These add components such as air ducts, fans, and heaters to a standard washing machine to achieve the function of drying clothes after washing. However, because the outer drum's exhaust vent is connected to the inner drum of the garment care device, foam or a small amount of moisture from the inner drum can escape through the outer drum's exhaust vent, potentially damaging the garment care device's exterior components. Summary of the Invention
[0003] To address the shortcomings of existing technologies, the present invention aims to provide a method, system, and device for controlling the exhaust port of the outer cylinder of a garment care device, which can prevent a small amount of foam or water vapor from overflowing through the air outlet pipe and causing damage to the exterior components of the garment care device.
[0004] In order to achieve the above-mentioned objectives and other advantages of the present invention, a first objective of the present invention is to provide a method for controlling the exhaust port of the outer cylinder of a garment care device, comprising the following steps:

[0017] The third objective is clearly to provide a garment care device.
[0018] It includes: a memory on which program code is stored; and a processor connected to the memory, which implements the above method when the program code is executed by the processor.
[0019] Compared with the prior art, the beneficial effects of the present invention are:
[0020] This invention detects the air pressure inside the outer cylinder exhaust port. When the air pressure at the outer cylinder exhaust port is zero, it controls the outer cylinder exhaust port to close, thus preventing foam or a small amount of water vapor from the inner cylinder of the garment care device from being discharged through the outer cylinder exhaust port and ultimately damaging the outer parts of the garment care device.

[0030] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.
[0031] In the following description, the use of suffixes such as "module," "part," or "unit" to denote elements is solely for the purpose of illustrative purposes and has no specific meaning in itself. Therefore, "module," "part," or "unit" may be used interchangeably.
[0032] Reference Figure 1 A method for controlling the exhaust port of the outer cylinder of a garment care device includes the following steps:
[0033] S01: Obtain the air pressure value at the exhaust port of the outer cylinder of the garment care device; wherein, a controllable damper is provided at the exhaust port of the outer cylinder;
[0034] S02: When the exhaust port air pressure is greater than zero, the exhaust port damper of the garment care device air duct is opened.
[0035] This invention determines whether the outer tube exhaust port of the garment care device is operational by detecting the presence of air pressure at the exhaust port. When the outer tube exhaust port is operational, the damper is open, allowing the exhaust port to connect with the outside environment; when the outer tube exhaust port is not operational, the damper is closed, isolating the exhaust port from the outside environment. This method prevents foam or small amounts of moisture from the inner tube of the garment care device from being discharged through the exhaust port when it is not operational, thus avoiding potential damage to the external components of the garment care device.
[0036] In some embodiments, obtaining the air pressure value at the exhaust port of the garment care device's outer drum includes obtaining the exhaust port air pressure value during the washing and / or rinsing and / or spin-drying and / or drying processes. Monitoring the exhaust port air pressure value during the washing and rinsing processes can effectively prevent situations where increased pressure changes in the inner drum during washing prevent gas from being trapped and damaged, thus avoiding damage to the inner drum and air duct. Monitoring the exhaust port air pressure value during the spin-drying process can prevent situations where the rapid rotation of the inner drum during spin-drying causes drastic changes in air pressure. Detecting the air pressure value during the drying process can quickly expel the gas generated during drying, ensuring air pressure balance within the garment care device's drum.
[0037] In some preferred embodiments, the outer cylinder exhaust port control method further includes the step of acquiring the exhaust port air pressure value of the garment care device after the damper is opened. When the exhaust port air pressure value continues to increase and does not decrease to zero, it is considered that the air duct is blocked. The garment care device is then controlled to discharge residual water from the cylinder and stop operation, followed by a restart for inspection. Monitoring the air pressure value after the damper is opened allows for timely determination of whether the garment care device's air duct is blocked, solving the problem that the air duct cannot be directly observed inside the garment care device, making it impossible to check for blockages.
[0038] In some preferred embodiments, the air pressure value of the garment care device is the air pressure value at the end where the air duct of the garment care device connects to the inner drum. By detecting the air pressure value at this point, the air pressure status of the air duct and the inner drum can be obtained in real time, thereby controlling the timely opening and closing of the damper. In addition, detecting the air pressure value at this point, compared with detecting the air pressure value at the air outlet, can simultaneously detect whether the air duct is blocked.
[0039] In some preferred embodiments, controlling the closure of the air outlet damper includes rotating the outer cylinder exhaust port damper to close the outer cylinder exhaust port. When the outer cylinder exhaust port is operating, there is a certain gap between the damper and the outer cylinder exhaust port to allow gas to escape. When the outer cylinder exhaust port is not operating, rotating the damper closes the outer cylinder exhaust port. By rotating the damper, no additional operating space is required, improving the space utilization of the garment care device. Furthermore, rotating the damper only requires rotating a certain angle to control whether the outer cylinder exhaust port is closed, making the control method simple, convenient, and highly forgiving.
[0040] The present invention will be described in more detail below through specific embodiments, in which the advantages of the present invention will be more significant.
[0041] Example 1
[0042] Reference Figure 2 A method for controlling the exhaust port of the outer cylinder of a garment care device, specifically including the following steps:
[0043] S11: Detect the air pressure at the outer cylinder exhaust port;
[0044] S12: Obtain the air pressure at the outer cylinder exhaust port and determine whether the air pressure at the outer cylinder exhaust port is zero.
[0045] S13: If the exhaust port pressure is greater than zero, it is assumed that there is gas in the air duct that needs to be discharged, and the exhaust port of the garment care device is opened.
[0046] S14: If the air pressure at the outer cylinder exhaust port is zero, it is assumed that the air pressure inside the garment care device is normal and there is no need to balance the air pressure. In this case, the air duct damper is kept closed, and the process returns to step S11.
[0047] In this embodiment, a pressure sensor installed at the outer cylinder exhaust port determines whether the exhaust port is in operation. If the pressure sensor reading is not zero, the exhaust port is considered to be working. In this case, the rotating damper is in a state of communication with the outside, keeping the exhaust port unobstructed to prevent air from being trapped and causing cracks in the air duct, and to prevent excessive pressure from damaging the air duct. If the pressure sensor reading is zero, the exhaust port is considered not working. In this case, the rotating damper is controlled to rotate, closing the air duct and preventing foam or small amounts of water from flowing out of the exhaust port and damaging the exterior components of the garment care device.
[0048] In some embodiments, the opening and closing of the outer cylinder exhaust port is controlled by detecting the humidity of the exhaust port when the air duct is not in operation. If the humidity of the outer cylinder exhaust port is detected to be greater than or equal to a first preset threshold, the damper of the outer cylinder exhaust port is controlled to rotate, thereby closing the outer cylinder exhaust port and shutting off the fan. Otherwise, the outer cylinder exhaust port is connected to the outside. By detecting humidity, the situation where the humidity of the outer cylinder exhaust port is too high and water accumulates, thus overflowing and damaging the exterior parts of the garment care device, is further avoided.
[0049] Example 2
[0050] Reference Figure 3 A method for controlling the exhaust port of the outer cylinder of a garment care device, specifically including the following steps:
[0051] S21: Detect the air pressure at the outer cylinder exhaust port;
[0052] S22: Obtain the air pressure at the exhaust port and determine whether the air pressure at the outer cylinder exhaust port is zero.
[0053] S23: If the air pressure at the outer cylinder exhaust port is zero, it is considered that the outer cylinder exhaust port is in a non-working state. Control the rotation of the air duct damper at the outer cylinder exhaust port to close the outer cylinder exhaust port.
[0054] S24: If the air pressure at the outer cylinder exhaust port is positive, proceed to the next step of judgment and check the operation of the air intake duct fan.
[0055] S25: If the air intake fan stops moving, control the outer cylinder exhaust port damper to rotate and close the outer cylinder exhaust port; otherwise, return to step S21.
[0056] In this embodiment, after determining that the air pressure at the outer cylinder exhaust port is not zero, the operation of the fan in the air inlet duct is also checked. If the fan is determined to be not working, it is assumed that there is no airflow in the duct and that there is essentially no air transmission at the outer cylinder exhaust port. In this case, the outer cylinder exhaust port damper is rotated to close the outer cylinder exhaust port. By detecting the fan status, the condition inside the duct can be obtained in real time, allowing for faster closure of the outer cylinder exhaust port and further preventing foam or small amounts of water from flowing out of the outer cylinder exhaust port and damaging the exterior components of the garment care device.
[0057] Example 3
[0058] Reference Figure 4 A control system for the outer cylinder exhaust port of a garment care device, comprising:
[0059] The information acquisition module 10 is configured to acquire information about the air pressure value at the exhaust port of the outer cylinder of the garment care device; the control module 20 is configured to receive information from the information acquisition module and control the opening and closing of the damper at the exhaust port of the outer cylinder of the garment care device.
[0060] The working principle of the outer cylinder exhaust port protection system is as follows: the air pressure in the air duct of the garment care device is obtained by the information acquisition module 10, and the information is sent to the control module 20. The control module 20 controls the opening and closing of the air damper of the garment care device.
[0061] In some preferred embodiments, the outer cylinder exhaust port control system further includes a pressure detection module 30, configured to acquire the air pressure inside the outer cylinder exhaust port. Specifically, this is a pressure sensor installed inside the outer cylinder exhaust port. Through real-time monitoring by the pressure sensor, the condition inside the air duct can be monitored in real time. When the air duct stops working, it is closed to prevent foam from flowing out and damaging the exterior parts of the garment care device.
[0062] In some preferred embodiments, the outer cylinder exhaust port control system further includes a fan detection module 40, configured to detect whether the fan in the air inlet duct is operating. By detecting whether the fan is operating, the outer cylinder exhaust port is closed when the fan stops operating, further preventing foam from overflowing from the outer cylinder exhaust port and damaging the exterior parts of the garment care device.
[0063] In some preferred embodiments, the outer cylinder exhaust port control system further includes a humidity detection module 50, configured to detect the humidity inside the outer cylinder exhaust port of the garment care device. Specifically, this is a humidity sensor installed inside the air duct. The humidity sensor can detect the humidity inside the air duct, preventing excessive water vapor foam from overflowing and causing damage to the appearance of the garment care device.
[0064] Example 4
[0065] Reference Figure 5 This embodiment provides a garment care device 1, including a memory storing program code thereon; and a processor connected to the memory, which implements the above-described method when the program code is executed by the processor.
[0066] The garment care device 1 also includes an inner drum of the washing tub and an air duct. The air duct is connected to the washing tub and includes an air inlet duct and an outer drum exhaust port. The outer drum exhaust port includes a sensor. The air duct opening is opened and closed by a rotatable damper 11. The sensor obtains the pressure inside the outer drum exhaust port in real time. When the pressure of the garment care device does not change and there is no airflow at the outer drum exhaust port, the rotatable damper 11 is rotated to close the air duct opening, thus preventing foam from flowing out and damaging the appearance of the garment care device.
