[0004] With the continuous improvement of manufacturing technology and the increasing demands of people's daily lives, garment processing equipment has entered thousands of households and become one of the most commonly used household appliances. Garment processing equipment is used to perform various processing steps on garments (washing, rinsing, ironing, drying, etc.).

[0005] Currently, some existing garment processing devices contain filters to remove clothing debris, paper scraps, lint, cotton fibers, or other impurities generated during processing. Over time, these debris and impurities can clog the filters, reducing their filtration efficiency. In addition, the inventors have discovered for the first time another reason that can lead to reduced filtration efficiency: a water film forms on the filter surface (at the pores). The presence of this water film renders the filter ineffective at filtering. Summary of the Invention

[0063] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely represents selected embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort (including new embodiments formed by combining features included in different embodiments) are within the scope of protection of this application.

[0064] It should be noted that similar reference numerals and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures. Furthermore, in the description of this application, terms such as "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0065] This application provides a garment processing device for washing, rinsing, ironing, and drying garments. The garment processing device includes, but is not limited to, washing machines, dryers, washer-dryer combos, and other garment processing equipment. Figure 1 The illustration depicts a garment processing device 1000 including a garment receiving device 1100 (which may include an inner drum and an outer drum) for receiving garments to be processed, a drying device 2000, and an air outlet duct 1300. The air outlet duct 1300 connects the garment receiving device 1100 and the drying device 2000. The air outlet duct 1300 is configured to guide airflow from the garment receiving device 1100 to the drying device 2000. The relative positions of the garment receiving device 1100 and the drying device 2000 are not fixed; they can be arranged vertically or front-to-back.

[0066] Figure 2 The diagram illustrates a drying device 2000 including a circulating fan 2100, a moisture absorption and desiccation component 2200, a moisture absorption and desiccation turntable drive unit 2300, and a regeneration fan 2400. The drying device 2000 also includes... Figure 2 The moisture absorption channel and regeneration channel are not shown in the diagram.

[0067] The air inlet of the moisture absorption channel is connected to the air outlet duct 1300 of the clothing holding device 1100. The air outlet of the moisture absorption channel is connected to the air inlet duct of the clothing holding device 1100. The air outlet of the moisture absorption channel can be connected to the air inlet duct of the clothing holding device 1100 via a connector. A circulating fan 2100 is located inside the moisture absorption channel to create a circulating airflow within the clothing holding device 1100 and the moisture absorption channel. A regeneration fan 2400 is located inside the regeneration channel to create a dehumidifying airflow within the regeneration channel.

[0068] The moisture absorption and desiccation component 2200 may include a moisture absorption and desiccation turntable 2201 (set in...) Figure 2 The moisture absorption and desiccation component 2200 has its interior housing. The moisture absorption and desiccation turntable 2201 is equipped with a desiccant for absorbing moisture. The desiccant can be, for example, zeolite (molecular sieve), alkali metal aluminosilicate (13X molecular sieve), lithium chloride, silica gel, modified silica gel, activated alumina, etc.

[0069] The moisture absorption and desiccation turntable drive unit 2300 is used to drive the moisture absorption and desiccation turntable 2201 to rotate relative to the moisture absorption channel and the regeneration channel. Both circulating airflow and desiccation airflow flow simultaneously on the moisture absorption and desiccation turntable 2201. The area on the moisture absorption and desiccation turntable 2201 through which the circulating airflow flows is the moisture absorption area, and the area through which the desiccation airflow flows is the regeneration area. In one possible example, the circulating airflow and the desiccation airflow flow through the moisture absorption and desiccation turntable 2201 in opposite directions.

[0070] The drying apparatus 2000 may further include a regeneration heating module 2500 and a condenser 2600 disposed on the regeneration channel. The regeneration heating module 2500 covers the regeneration area of ​​the moisture absorption and desiccation component 2200 (moisture absorption and desiccation turntable 2201) and is used to heat the regeneration area of ​​the moisture absorption and desiccation component 2200 (moisture absorption and desiccation turntable 2201) to desorb the moisture absorbed by the moisture absorption and desiccation component 2200 (moisture absorption and desiccation turntable 2201). The condenser 2600 is used to condense the exhaust airflow flowing out from the regeneration area of ​​the moisture absorption and desiccation component 2200 to dry the exhaust airflow.

[0071] In one embodiment, the drying device 2000 further includes a housing, making the drying device 2000 a single integrated module. In one embodiment, the housing includes a first housing and a second housing accommodating the moisture-absorbing and desiccant turntable 2201. In one embodiment, a first partition is provided on the first housing, and a second partition is provided on the second housing. When the first housing and the second housing are connected, the space formed by the first housing, the second housing, and the moisture-absorbing and desiccant turntable 2201 can be divided into at least two relatively isolated spaces, namely, a first space and a second space, or a moisture-absorbing space and a regeneration space, or a moisture-absorbing area and a regeneration area. The relative isolation of the first space and the second space can be understood as: the airflow exchange between the first space and the second space is restricted by certain sealing measures, preventing free flow.

[0072] A filter 601 is installed in the air outlet duct 1300 to filter the airflow. The clothing processing equipment further includes a water film detection device and a water film removal device.

[0073] The water film detection device is used to detect changes in system parameters within the garment processing equipment and determine the presence of a water film on the filter screen 601 based on these changes. System parameters include one or more of temperature, pressure, and current. The water film removal device is used to remove the water film from the filter screen.

[0074] The water film detection device is used to detect and determine whether a water film exists on the filter screen 601. The water film detection device can be implemented in various ways, such as by detecting system parameters in the processing equipment, such as temperature, pressure, current, fan power, etc. Since there are multiple temperature points in the garment processing equipment, determining which temperature point is used as the basis for detecting whether a water film has formed on the filter screen requires special design by the inventor to achieve accurate detection. The water film removal device is activated when a water film is detected on the filter screen 601 to remove it promptly. The water film removal device can also be implemented in various ways, such as by actively moving the filter screen 601 to remove the water film, by using other devices to assist in removing the water film, or by using existing devices in the equipment for water film removal, etc.

[0075] In this embodiment, the water film detection device and the water film removal device can detect the filtration status of the filter screen 601 in real time during equipment operation. Once a water film appears on the filter screen, it can be detected in time and removed quickly to ensure that the filter screen 601 is always working in an effective filtration state.

[0076] In one embodiment, the water film detection device includes a temperature sensor disposed at the air outlet of the clothing holding device. This sensor detects the temperature near the air outlet (a temperature point in the temperature field of the cross-section where the air outlet is located) and determines whether a water film exists on the filter 601 based on the temperature level. In one embodiment, the filter 601 is considered to have a water film and needs to be cleaned if the temperature near the air outlet exceeds 60°C. Normally, the temperature near the air outlet of the clothing holding device can be set at 53±5°C (e.g., 50°C, 53°C, 55°C, 57°C, or 58°C). If a water film forms on the filter 601, the circulating airflow through the air outlet duct will be obstructed. The circulating airflow, having been processed by the drying device, will increase in temperature and enter the clothing holding device. When the heated circulating airflow exits the clothing holding device, it becomes a slightly warmer and more humid airflow. This airflow cannot quickly pass through the filter 601 and accumulates near the air outlet, causing the temperature near the air outlet to rise (compared to normal). Therefore, it can be set that if the temperature near the air outlet of the clothing container exceeds 60°C, it is determined that there is a water film on the filter 601 and it needs to be cleaned.

[0077] In one embodiment, the garment processing equipment further includes a condensation module (which may include a water-cooled condenser), and the water film detection device includes a temperature sensor disposed at the air inlet and / or air outlet of the condensation module, for detecting the temperature near the air inlet and / or air outlet of the condensation module, and determining whether there is a water film on the filter 601 by the temperature change near the air inlet and / or air outlet of the condensation module.

[0078] In one embodiment, the drying device 2000 includes a circulation module, a dehumidification module, a regeneration module, and a condensation module. The circulation module includes a circulation fan 2100 for drawing in humid airflow from the garment processing device and forming a circulating airflow. The dehumidification module includes a moisture-absorbing and desiccant disc 2201 for absorbing moisture from the circulating airflow, thus transforming the circulating airflow after passing through the moisture-absorbing and desiccant disc 2201 into a dry airflow. The regeneration module includes a regeneration fan 2400 and a regeneration heating module 2500. The regeneration heating module 2500 heats the moisture-absorbing and desiccant disc 2201 and the regeneration airflow. The condensation module is connected to the regeneration air outlet of the regeneration fan 2400 and condenses the high-temperature, high-humidity regeneration airflow output from the regeneration air outlet to form a low-temperature, dry airflow. The area on the moisture-absorbing and desiccant disc 2201 through which the circulating airflow passes is the dehumidification section, and the area through which the regeneration airflow passes is the regeneration section.

[0079] The water film detection device includes a temperature sensor located at the air inlet and / or outlet of the condenser module. This sensor detects the temperature near the air inlet and / or outlet of the condenser module and determines whether a water film exists on the filter 601 based on temperature changes near the air inlet and / or outlet. In this embodiment, if a water film forms on the filter 601, airflow ceases, and the temperature of the circulating airflow (the airflow entering the clothing container) increases. The temperature of the dehumidification section also increases, as does the temperature of the regeneration zone (with the regeneration heating module 2500), and the temperatures entering and exiting the condenser 2600 all rise. In this embodiment, the device can be configured to determine the presence of a water film on the filter 601 and require removal when the temperature near the air inlet of the condenser 2600 is greater than or equal to 100°C. Alternatively, the device can be configured to determine the presence of a water film on the filter 601 and require removal when the temperature near the air outlet of the condenser 2600 is greater than or equal to 90°C.

[0080] In one embodiment, the water film detection device includes a load current detector for detecting the magnitude of the load current of the circulating fan 2100. In this embodiment, in constant speed mode, when the load current of the circulating fan 2100 decreases, it is determined that a filter water film exists and needs to be removed. In constant power mode, when the load current of the circulating fan 2100 increases, it is determined that a filter water film exists and needs to be removed.

[0081] In one embodiment, the water film detection device includes a pressure sensor disposed in the air outlet duct 1300 between the filter 601 and the drying device 2000. In this embodiment, the pressure sensor can be positioned in various ways. The water film detection device is used to detect whether the pressure change rate in the air outlet duct 1300 reaches a preset threshold, such as whether the pressure change rate reaches 20%.

[0082] In one embodiment, the water film removal device is a filter screen 601 vibrator connected to the filter screen 601, used to remove the water film by controlling the vibration frequency of the filter screen 601 vibrator. In this embodiment, the filter screen 601 vibrator can be configured as a sheet-like structure formed on the non-filtering surface of the filter screen 601. The filter screen 601 vibrator includes a control motor and a vibrating plate, which is attached to the non-filtering surface of the filter screen 601. The vibrating plate includes a third hole, the diameter of which is larger than the diameter of the second hole 6013. When a water film is detected on the filter screen, the control motor of the filter screen 601 vibrator starts, controlling the vibrating plate to vibrate at a specific frequency to remove the water film on the filter screen 601. In this embodiment, the filter screen 601 can resonate at the same frequency as the vibrating plate, resulting in a better water film removal effect.

[0083] In one embodiment, the water film removal device is a power applicator. The power applicator includes a power generating module and at least one power ball. The power generating module is connected to the at least one power ball and is used to generate power at different frequencies. The power ball and the filter screen 601 are spaced apart, and the distance between the spaced distance is related to the distance the power ball travels. The distance the power ball travels is greater than or equal to the distance between the spaced distances.

[0084] When a water film is detected on the filter screen 601, the power ball, when the power applicator is turned on, is in contact with the surface (non-filter surface) of the filter screen 601. The force applied by the power ball to the filter screen 601 can break the water film on the filter screen 601 and remove the water film.

[0085] In one set of embodiments, this application also provides a garment processing device, further including a water film detection device.

[0086] The water film detection device is used to detect changes in system parameters in the garment processing equipment and determine whether a water film exists on the filter 601 based on these changes. System parameters include one or more of temperature, pressure, and current.

[0087] When the water film detection device detects the presence of a water film on the filter 601, the fan and / or heater in the garment processing equipment operate at higher power.

[0088] In this embodiment, the water film on the filter screen is removed by using the structural components of the clothing processing equipment itself. This reduces the need for modifications to the clothing processing equipment, saves design space, increases the functionality of the structural components of the clothing processing equipment, and effectively removes the water film from the filter screen.

[0089] In one embodiment, the fan in the garment processing device includes a circulating fan 2100 for drawing in humid airflow from the garment processing device and forming a circulating airflow. When the water film detection device detects the presence of a water film on the filter 601, the circulating fan 2100 operates at a higher power or maximum power to form a stronger airflow to eliminate the water film.

[0090] In one embodiment, when the circulating fan 2100 operates at a higher power, it directs the airflow in a predetermined direction, which is the direction in which the airflow sequentially flows through the garment holding device, the filter 601, the drying device 2000, and back to the garment holding device. In this embodiment, the circulating fan 2100 preferably rotates in the direction that generates the normal operating airflow, to prevent the reverse airflow generated by the circulating fan 2100 from expelling lint and impurities from the air inlet of the garment holding device and thus preventing them from being blown into the drying device 2000 and absorbed by the moisture-absorbing and desiccant disc 2201.

[0091] The garment handling equipment also includes a first heater for heating the washing water in the garment holding device.

[0092] The heater in the garment processing equipment includes a first heater and / or a regeneration heating module 2500. When the water film detection device detects the presence of a water film on the filter 601, the first heater and / or the regeneration heating module 2500 operate at a higher power or maximum power to increase the temperature within the air outlet duct 1300, thereby further improving the efficiency of water film removal.

[0093] It is understood that when it is necessary to remove the water film, the fan and heater of the clothing treatment equipment in the above embodiments, the vibrator of the filter screen 601 in the above embodiments, and the power applicator in the above embodiments can be used individually or in combination to enhance the water and ink removal effect of the filter screen 601.

[0094] In one set of embodiments, this application also provides a control method for a clothing processing device, the clothing processing device including: a clothing holding device, a drying device 2000, and an air outlet duct 1300 connecting the clothing holding device and the drying device 2000, the air outlet duct 1300 being configured to guide airflow from the clothing holding device to the drying device 2000.

[0095] A filter 601 is installed in the air outlet duct 1300 to filter the airflow. The control method for the garment processing equipment includes detecting changes in system parameters within the garment processing equipment, including one or more of temperature, pressure, and current.

[0096] The presence of a water film on filter screen 601 is determined based on changes in system parameters.

[0097] When a water film is detected on filter screen 601, the circulating fan 2100 is controlled to operate at a higher power or maximum power. And / or, when a water film is detected on filter screen 601, the regeneration heating module 2500 is controlled to operate at a higher power or maximum power.

[0098] In one embodiment, the garment processing device further includes a water film removal device. When a water film is detected on the filter 601, the water film removal device is controlled to vibrate at a first frequency to remove the water film.

[0099] In this embodiment, the water film removal device can be either actively vibrating the filter screen 601 or having the filter screen 601 struck by a powered device. The magnitude of the first frequency is adjustable. The adjustment of the first frequency is based on the degree of change in system parameters.

The air inlet of the air outlet duct 1300 is located on the rear wall of the outer tub, and the air outlet of the air outlet duct 1300 is located on the side wall of the outer tub to ensure the airtightness between the air outlet duct 1300 and the outer tub, while also saving space in the garment holding device. The air outlet of the air outlet duct 1300 is connected to the air inlet of the garment holding device.

[0105] The airflow circulation process in the clothing holding device may include: high-humidity gas in the inner drum enters the outer drum through the water-permeable and air-permeable holes of the inner drum, passes through the air inlet of the air outlet duct 1300 set on the rear wall of the outer drum, reaches the filter screen 601 in the air outlet duct 1300, filters out lint and impurities through the filter screen 601, and then enters the air outlet of the air outlet duct 1300 set on the side wall of the outer drum, reaches the drying device 2000, and the high-humidity gas is filtered into high-temperature dry gas by the drying device 2000 before entering the inner drum.

[0106] In one embodiment, the inner cylinder is a first cylinder, and the outer cylinder is a second cylinder. The diameter of the second cylinder is larger than the diameter of the first cylinder. The central axes of the first and second cylinders may coincide. An air outlet duct 1300 is sealed and installed on the rear wall of the outer cylinder. The rear wall of the outer cylinder, the air outlet duct 1300, and the side wall of the outer cylinder together form an air outlet channel. The rear wall of the outer cylinder is flat, and the side wall of the outer cylinder is an arc surface.

[0107] In one embodiment, such as Figure 3 As shown, the air outlet duct 1300 includes a vertical channel communicating with the drying device 2000 and an arc-shaped channel communicating with the clothes holding device. When the filter 601 is installed in the air outlet duct 1300, it can be installed only in the vertical duct, or it can be installed in both the vertical duct and the arc-shaped duct. Figure 3 The black arrow in the middle indicates the direction of airflow.

[0108] In one embodiment, the curvature of the arc-shaped channel is less than or equal to the curvature of the side of the clothing holding device, which ensures that the air outlet duct 1300 is completely located on the rear wall of the outer cylinder.

[0109] In one embodiment, a filter 601 is installed in the air outlet duct 1300 to filter airflow; the filter 601 covers more than half of the vertical channel length. In this embodiment, the filter 601 is only installed in the vertical duct, simplifying the installation and fixing process; installing the filter 601 on a vertical channel allows for a larger filter area than installing it on an arc-shaped channel. Specifically, the filter 601 covers more than half of the vertical channel length. For example, the filter 601 covers four-fifths of the vertical channel length.

[0110] In one embodiment, the inner cylinder is cylindrical. The outer cylinder is polyhedral, preferably tetrahedral, pentahedral, hexahedral, etc. The air outlet duct 1300 is sealed and installed on the rear wall or side wall of the outer cylinder.

[0111] When the air outlet duct 1300 is installed on the side wall of the outer cylinder, it is installed on one side of the outer cylinder side wall. For example, if the outer cylinder is a pentahedron, the rear wall of the outer cylinder is one bottom surface of the pentahedron, and the surface opposite the rear wall of the outer cylinder is the other bottom surface of the pentahedron, corresponding to the clothing insertion port of the clothing holding device. The air outlet duct 1300 is installed on one of the five side walls of the outer cylinder. The rear wall of the outer cylinder, the air outlet duct 1300, and the side wall of the outer cylinder together form a sealed air outlet channel.

[0112] In one embodiment, such as Figure 4 and Figure 5As shown, the air outlet duct 1300 includes a first end 1301 near the clothes holding device and a second end 1302 near the drying device 2000. One end of the filter screen 601 is near the first end 1301 and the other end of the filter screen 601 is near the second end 1302.

[0113] In a specific embodiment, the first end portion 1301 is located at the rear of the clothing holding device and is connected to the air outlet of the clothing holding device. The second end portion 1302 is located at the rear of the clothing holding device and is connected to the adapter portion 1303 located on the side wall of the clothing holding device. The adapter portion 1303 is connected to the drying device 2000, and the design of the adapter portion 1303 can save more space. Figure 5 The diagram also illustrates the cleaning nozzle 602 and the nozzle water supply pipe 603, which are located within the air outlet duct 1300 along the air inlet direction. Figure 5 The airflow from the washing machine drum is arranged sequentially (in the direction of the black arrow in the middle) so that the airflow first passes through the filter screen 601 to filter out lint and impurities contained in the airflow.
