Description

Technical Field

[0001] This application relates to the field of clothing processing equipment technology, and in particular to a clothing processing equipment and drying control method. Background Technology

[0002] As people's demand for intelligent laundry equipment increases, laundry equipment with drying functions is becoming increasingly common. Users simply need to select the drying function on the laundry equipment, and the equipment will intelligently dry the clothes.

[0003] In the aforementioned drying process, the washing machine typically executes the drying process based on user-set operating parameters or preset parameters until the drying stop condition is met. The drying time is usually determined based on a preset drying time. However, many factors influence the drying time (e.g., heating environment factors), and these factors vary complexly, making the drying process complex and variable. Therefore, using the aforementioned preset drying time is not suitable for this complex and variable process. Consequently, the accuracy of the drying time determined using this static method is low. Summary of the Invention

[0004] This application provides a garment processing device and a drying control method to at least solve the problem of unreasonable garment drying degree in related technologies.

[0005] In a first aspect, a garment processing device is provided, comprising: an inner drum for containing target garments; a motor for driving the inner drum to rotate; a weight detection device for detecting the weight of the target garments; and a controller; the controller is connected to the inner drum, the motor, and the weight detection device; the controller is configured to: determine a first target weight of the target garments and a target rotational speed of the motor during the drying process when the garment processing device is started to execute a drying operation program according to target operating parameters; the target operating parameters include the target rotational speed; determine a target weight range corresponding to the first target weight and the target rotational speed based on the weight of the target garments when the drying operation program is started and the correspondence between the motor rotational speed and the drying weight range; the drying weight range characterizes the weight range of the target garments when they reach a preset drying degree; control the weight detection device to detect a second target weight of the target garments during the drying operation to obtain the second target weight; and stop executing the drying operation program when the second target weight is within the target weight range.

[0006] The aforementioned second target weight being within the target weight range serves as a drying condition that satisfies the degree of drying.

[0007] The technical solution provided in this application provides at least the following beneficial effects: The garment processing equipment can determine the target weight range of the garment after it has reached the target drying degree based on the initial weight of the garment and the correspondence between the motor speed and the drying weight range; it then monitors the second target weight of the garment in real time during the drying process and determines whether the second target weight is within the target weight range. When the second target weight is within the target weight range, the drying process is terminated. The garment processing equipment is configured with different motor speeds and different initial weights to determine the required weight range after drying; therefore, during the drying process, when the garment reaches the target weight range, it indicates that the garment is dried, and the drying process is stopped. The above-mentioned method of flexibly determining the drying time based on the target weight range ensures that the dried garment reaches the target drying degree and is not affected by different drying environmental factors (such as drying temperature, air flow speed, etc.) during the drying process, which may result in incomplete or over-drying of the garment.

[0008] Furthermore, drying methods in related technologies that use a temperature change value exceeding a preset temperature as the drying condition require additional temperature sensors to acquire the temperature change value. Therefore, compared to the aforementioned related technologies, the drying method in this application, which uses the target garment being within a target weight range during the drying process as the drying stop condition, eliminates the need for additional temperature sensors, reducing the manufacturing cost of the garment processing equipment, thereby lowering user operating costs and improving the user experience.

[0009] In some embodiments, the controller is further configured to: determine the target moisture content corresponding to the target drying level based on the target drying level corresponding to the drying operation program.

[0010] The target drying level mentioned above corresponds to the target degree of drying. This target drying level can be set by the user or preset by the garment processing equipment.

[0011] In this embodiment, the garment processing equipment establishes a correspondence between drying levels and target moisture content, and the drying operation program is associated with the target drying level. Based on this, the controller can determine the target moisture content based on the drying operation program.

[0012] In some embodiments, the controller is specifically configured to determine a first target weight and a target weight range corresponding to a target rotation speed based on the correspondence between the weight of the target garment when the drying operation is started and the rotation speed of the motor and the drying weight range; specifically, it is configured to perform: determining a first target weight, a target rotation speed, and a target weight range corresponding to a target moisture content based on the correspondence between the weight of the target garment when the drying operation is started, the rotation speed of the motor, and the moisture content of the target garment and the drying weight range.

[0013] It should be noted that garments of the same weight but different materials, dried at the same motor speed, will have essentially the same moisture content. Therefore, given a constant motor speed, if the initial weight and target moisture content of the target garment are determined, the weight of the dried garment will fall within a certain range.

[0014] In this embodiment, the garment processing equipment pre-stores the weight of the target garment during the drying process, the motor speed, and the correspondence between the moisture content of the target garment and the drying weight range. This allows the garment processing equipment to determine the target drying weight range based on the first target weight, target motor speed, and target moisture content. Based on this embodiment, considering the user's needs for the degree of garment drying—that is, the different users' requirements for the moisture content of the dried garment—different weight ranges are further set for different moisture contents at different drying degrees to ensure that the dried garments better meet the user's drying needs.

[0015] In some embodiments, the garment processing device further includes: a water inlet valve for introducing water into the water inlet channel according to a target control sequence during the drying process; the target control sequence represents a first duration of continuous water injection into the water inlet channel and a second duration of cessation of water injection into the water inlet channel; a drying heating tube for heating the target garment according to a target heating duration; and a fan for providing airflow to the cavity of the inner drum according to a target operating speed; the target operating parameters further include the target control sequence, the target heating duration, and the target operating speed.

[0016] In this embodiment, the target operating parameters, including the target control timing, target heating time, target operating speed, and target rotation speed, are kept constant to reduce the impact on the moisture content of the target clothes after drying. This ensures that the target weight range is determined more accurately based on the weight at the start of the drying process, the motor speed, and the correspondence between the moisture content of the target clothes and the drying weight range.

[0017] In some embodiments, the controller is further configured to control the garment processing equipment to execute a drying operation program according to the target operating parameters when the second target weight is outside the target weight range.

[0018] It is understandable that during the drying process, if the drying conditions are not met, the second target weight is greater than or equal to the larger of the target weight range.

[0019] In this embodiment, the target weight range is used as the execution condition for the drying program, which ensures the normal execution of the drying process.

[0020] In some embodiments, the controller is further configured to stop executing the drying operation when the execution time of the drying operation by the garment handling equipment reaches a time threshold.

[0021] Based on this, a time threshold is used to limit the maximum execution time of the drying operation program to prevent the drying process from continuing due to factors such as the water inlet valve not receiving water or the flow rate being too low.

[0022] In some embodiments, the second target weight is obtained according to a preset cycle; when the second target weight is within the target weight range, the drying operation program is stopped; specifically configured to: obtain the second target weight for a consecutive preset number of preset cycles; when the second target weight in each of the preset number of preset cycles is within the target weight range, the drying operation program is stopped.

[0023] Based on this, the drying condition is terminated when the drying condition is reached a preset number of times. This ensures that the target clothing meets the drying condition multiple times at the end of the drying process, thus ensuring that the target clothing is in a stable drying state and avoiding the erroneous operation of mistakenly judging that the target clothing meets the drying condition in one instance.

[0024] In some embodiments, the controller is also configured to perform a dehydration process on the target garment before determining the first target weight of the target garment.

[0025] Based on this, the impact of excessive moisture in the target clothing on the drying process is taken into consideration. If the target clothing is completely soaked, directly drying the wet clothing may result in excessively long drying time or failure to dry at all. Therefore, the target clothing is first dehydrated before starting the drying function to ensure drying efficiency.

[0026] Secondly, a drying control method for a garment processing device is provided. This method includes: when starting the garment processing device and executing a drying operation program according to target operating parameters, determining a first target weight of the target garment and a target rotational speed of the motor during the drying process; the target operating parameters include the target rotational speed; determining a target weight range corresponding to the first target weight and the target rotational speed based on the weight of the target garment at the start of the drying operation program and the correspondence between the motor rotational speed and the drying weight range; the drying weight range characterizes the weight range of the target garment when it reaches a preset drying degree; controlling a weight detection device to detect a second target weight of the target garment during the drying operation to obtain the second target weight; and stopping the execution of the drying operation program when the second target weight is within the target weight range.

[0027] In some embodiments, the drying control method further includes:

[0028] Based on the target drying level corresponding to the drying operation procedure, determine the target moisture content corresponding to the target drying level.

[0029] Thirdly, embodiments of this application provide a computer-readable storage medium storing instructions that, when executed on any of the aforementioned devices, cause the devices to perform the drying control method of any of the aforementioned garment processing devices.

[0030] Fourthly, embodiments of this application provide a chip, including: a processor and a memory; the memory is used to store computer execution instructions, the processor is connected to the memory, and when the chip is running, the processor executes the computer execution instructions stored in the memory to cause the chip to execute any of the above-described drying control methods for clothing processing equipment.

[0031] Fifthly, embodiments of this application provide a computer program product containing instructions that, when run on any of the aforementioned devices, causes the device to execute the drying control method of any of the aforementioned garment processing devices.

[0032] In the embodiments of this application, the names of the components of the above-mentioned device do not limit the device itself. In actual implementation, these components may appear under other names. As long as the function of each component is similar to that of the embodiments of this application, it falls within the scope of the claims of this application and its equivalents.

[0043] 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. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0044] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, unless otherwise stated, "a plurality of" means two or more.

[0045] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "connected" and "linked" should be interpreted broadly, for example, as a fixed connection, a detachable connection, or an integral connection. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances. Furthermore, when describing pipelines, the terms "connected" and "linked" as used in this application have the meaning of establishing electrical connection. The specific meaning needs to be understood in conjunction with the context.

[0046] In the embodiments of this application, the terms "exemplary" or "for example" are used to indicate that something is an example, illustration, or description. Any embodiment or design that is described as "exemplary" or "for example" in the embodiments of this application should not be construed as being more preferred or advantageous than other embodiments or design. Specifically, the use of the terms "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.

[0047] As people's demand for intelligent laundry equipment increases, laundry equipment with drying functions is becoming increasingly common. Users simply need to select the drying function on the laundry equipment, and the equipment will intelligently dry the clothes.

[0048] In the aforementioned drying process, the washing machine typically executes the drying process based on user-set operating parameters or preset parameters until the drying stop condition is met. The drying time is usually determined based on a preset drying time. However, many factors influence the drying time (e.g., heating environment factors), and these factors vary complexly, making the drying process complex and variable. Therefore, using the aforementioned preset drying time is not suitable for this complex and variable process. Consequently, the accuracy of the drying time determined using this static method is low.

[0049] In view of this, embodiments of this application provide a garment processing device that can determine the target weight range of the target garment after it has reached the target drying degree based on the initial weight of the target garment and the correspondence between the motor speed and the drying weight range; then, it can detect the second target weight of the target garment in real time during the drying process and determine whether the second target weight is within the target weight range. When the second target weight is within the target weight range, it determines that the drying operation program has ended.

[0050] The aforementioned garment processing equipment is designed with different motor speeds and initial weights to determine the desired weight range for the dried garments. During the drying process, once the target garment reaches the target weight range, it is considered dry and the drying process stops. This method of flexibly determining the drying time based on the target weight range ensures that the garments achieve the desired level of dryness and prevents incomplete or over-drying due to environmental factors (such as drying temperature and airflow speed).

[0051] Furthermore, drying methods in related technologies that use a temperature change value exceeding a preset temperature as the drying condition require additional temperature sensors to acquire the temperature change value. Therefore, compared to the aforementioned related technologies, the drying method in this application, which uses the target garment being within a target weight range during the drying process as the drying stop condition, eliminates the need for additional temperature sensors, reducing the manufacturing cost of the garment processing equipment, thereby lowering user operating costs and improving the user experience.

[0052] In this application embodiment, the clothing processing equipment can be a drum clothing processing equipment with drying function, i.e., a drum washing machine, or a pulsator clothing processing equipment with drying function, i.e., a pulsator washing machine, etc. To further describe the solution of this application, the mechanical structure of a clothing processing equipment provided in this application embodiment will be introduced next using a drum clothing processing equipment as an example.

[0053] refer to Figure 1The garment processing equipment 10 may include one or more of the following: housing 101, door 102, drum assembly 103, motor 104, water inlet valve 105, drain valve 106, display 107, controller 108, fan 109, drying heating tube 110, temperature detection device 112, and water level detection device 111.

[0054] In some embodiments, a motor 104 is used to drive the inner drum to rotate. A temperature detection device 112 is installed at the bottom of the water inlet channel of the garment processing equipment; it is used to detect the water temperature in the water inlet channel. A water inlet valve 105 is used to introduce water into the water inlet channel according to a control sequence during the drying process; the control sequence represents the water inlet volume corresponding to a first duration of continuous water injection into the water inlet channel and a second duration of cessation of water injection into the water inlet channel. A drying heating tube 110 is used to heat the interior of the inner drum cavity. A fan 109 is used to provide airflow into the interior of the inner drum cavity. A water level detection device 111 is used to detect the temperature inside the inner drum.

[0055] In some embodiments, a water level detection device (not shown) is also included for detecting the water level height in the inlet channel. Specifically, when the water level height is greater than or equal to a height threshold, a drainage process is performed to discharge the water from the inlet channel.

[0056] In some embodiments, the housing 101 may form the overall appearance of the garment processing device 10 and seal the channels for contact between the inside and outside of the garment processing device 10, thereby preventing damage to electrical components. In the embodiments provided in this application, the housing 101 is generally arranged in a cuboid shape.

[0057] In some embodiments, the door 102 can be rotatably mounted on the housing 101, and the loading and unloading of clothing in the garment handling device 10 can be achieved by opening and closing the door 102. Specifically, the door 102 can be rotatably connected to the housing 101 via a door hinge.

[0058] In some embodiments, the garment processing device 10 further includes a water heating pipe 117, and a temperature detection device 112 is disposed on the water heating pipe 117.

[0059] Optionally, the door 102 can be made of transparent material to allow users to easily observe the condition of the clothes when the clothing processing equipment 10 is working.

[0060] In some embodiments, the tub assembly 103 is disposed inside the housing 101 to perform functions such as washing or drying clothes in the clothing processing device.

[0061] In some embodiments, the tub assembly 103 may include an inner tub 1031 and an outer tub 1032. The inner tub 1031 is used to hold the target clothing and includes dehydration holes. The outer tub 1032 is used to store washing water. When the drain valve 106 is closed, since the outer tub 1032 does not have other drain outlets, the washing water can be temporarily stored in the outer tub 1032.

[0062] In some embodiments, a certain gap is left between the inner drum 1031 and the outer drum 1032. For example, when the garment processing equipment performs a dehydration process, the garments remain in the inner drum 1031, and the control motor 104 drives the drum assembly 103 to rotate at the target dehydration speed to dehydrate the garments. During this process, water flows out from the dehydration hole, flows through the gap between the inner drum 1031 and the outer drum 1032 into the drain pipe, thereby achieving the purpose of spinning or drying the garments.

[0063] In some embodiments, the motor 104 is used to drive the drum assembly 103 to rotate, so that the rotating drum assembly 103 drives the clothes and washing water inside the drum assembly 103 to rotate, providing power support for the clothes handling equipment 10 to run the washing program.

[0064] In some embodiments, the water inlet valve 105 can be used to control the flow of water into the drum assembly 103. For example, when the water inlet valve 105 receives a water inlet command from the controller 108, the water inlet valve 105 opens to allow water to flow into the drum assembly 103 of the garment processing device 10, thereby enabling the garment processing device 10 to perform subsequent procedures such as washing and dehydration.

[0065] In some embodiments, the drain valve 106 is used to receive a drain command from the controller 108 when the washing process is finished and drainage is required, and the drain valve 106 opens to allow the washing wastewater to be discharged smoothly.

[0066] In some embodiments, the display 107 may be a liquid crystal display or an organic light-emitting diode (OLED) display. The specific type, size, and resolution of the display 107 are not limited, and those skilled in the art will understand that the display 107 can be modified in terms of performance and configuration as needed.

[0067] In some embodiments, the display 107 may be used to display the control panel of the garment processing device 10 or other image information. For example, the garment processing device 10 may display current operating information of the garment processing device on the display 107, such as the type of washing program, the duration and remaining duration of the washing program, and the amount of water used for washing.

[0068] In some embodiments, controller 108 refers to a device that can generate operation control signals based on instruction opcodes and timing signals to instruct the garment processing device 10 to execute control instructions. Exemplarily, controller 108 can be a central processing unit (CPU), a network processor (NP), a digital signal processor (DSP), a programmable logic device (PLD), a microprocessor, a microcontroller, or any combination thereof. The controller can also be other devices with processing functions, such as circuits, devices, or software modules; this application embodiment does not impose any limitations on this.

[0069] For example, the controller 108 can start the drying function of the clothing processing equipment; determine the target weight range of the target clothing after it reaches the target drying degree based on the initial weight of the target clothing and the correspondence between the motor speed and the drying weight range; then detect the second target weight of the target clothing in real time during the drying process, and determine whether the second target weight is within the target weight range. When the second target weight is within the target weight range, determine that the drying operation program ends.

[0070] Figure 2 An exemplary circuit system architecture diagram of the garment processing device 10 is shown.

[0071] like Figure 2 As shown, the garment processing device 10 may also include: an alarm device 114, a communication device 115, a human-computer interaction device 116, and a power supply 113.

[0072] Among them, the motor 104, water inlet valve 105, water outlet valve 106, display 107, early warning device 114, fan 109, drying heating tube 110, temperature detection device 112 and water level detection device 111, water heating tube 117, communication device 115, human-machine interaction device 116 and power supply 113 are all connected to the controller 108.

[0073] In some embodiments, the warning device 114 is used to send corresponding prompt information when starting or stopping the drying operation program to inform the user of the stage of the drying process. In some embodiments, the communication device 115 is a component used to communicate with external devices or external servers according to various communication protocol types. For example, the communication device may include at least one of the following: a Wi-Fi chip, a Bluetooth communication protocol chip, a wired Ethernet communication protocol chip, or other network communication protocol chips or near-field communication protocol chips, and an infrared receiver.

[0074] In some embodiments, the garment processing device 10 can transmit control signals and data signals with user-used terminal devices (e.g., mobile phones, tablets, wearable mobile devices, etc.), other home appliances (e.g., air conditioners, monitoring equipment, etc.), and servers via the communication device 115. For example, if a user issues a command to activate the quiet mode via a mobile phone, the garment processing device 10 receives the command via the communication device 115, and in response to the user's command to activate the quiet mode, the controller 108 of the garment processing device 10 activates the quiet mode.

[0075] In some embodiments, the human-computer interaction device 116 is used to enable interaction between the user and the laundry processing device 10. The human-computer interaction device 116 may include one or more of physical buttons, a touch display panel, or a voice recognition device. For example, the user can start the laundry processing device 10 by using the human-computer interaction device, and can also set the washing program to be run by the laundry processing device 10 by using the human-computer interaction device 116.

[0076] In some embodiments, the power supply 113, under the control of the controller 108, provides power supply support for the garment processing device 10 by using the power input from the external power source.

[0077] Based on the above-mentioned clothing processing equipment, such as Figure 3 As shown in the figure, this application provides a drying control method for a garment processing device, which includes the following steps:

[0078] Step S301: When starting the garment processing equipment and executing the drying operation program according to the target operating parameters, determine the first target weight of the target garment and the target speed of the motor during the drying process.

[0079] The aforementioned target operating parameters include the target rotation speed. Furthermore, the target rotation speed is constant throughout the drying process. The initial target weight can be understood as the initial weight of the target garments when the drying program is started.

[0080] For ease of description, the term "clothing" will be used to refer to the target clothing in the following text.

[0081] The aforementioned method of initiating the drying program can be implemented using a startup signal. This startup signal can be a user-input signal to activate the drying program. For example, if the user only needs to dry the clothes individually, they would place the clothes into the drum assembly and select the confirmation button on the "drying control" of the clothing handling device, thus generating a drying startup signal. Alternatively, the startup signal can be a signal generated when the drying program is about to begin during the execution of various washing functions. For example, a signal generated when the drying program is about to begin after the washing program has finished. Therefore, this application does not specifically limit the method of initiating the drying function.

[0082] In some implementations, the target operating parameters also include the target control timing, the target heating duration, and the target operating speed.

[0083] The aforementioned target operating parameters can be determined based on the garment processing equipment, which includes the following devices.

[0084] (1) Water inlet valve, used to introduce water into the water inlet channel according to the target control sequence during the drying process; the target control sequence represents the first duration of continuous water injection into the water inlet channel and the second duration of stopping water injection into the water inlet channel. (2) Drying heating tube, used to heat the target clothing according to the target heating duration. (3) Fan, used to provide air energy to the cavity of the inner drum according to the target operating speed.

[0085] In this embodiment, the target operating parameters, including the target control timing, target heating time, target operating speed, and target rotation speed, are kept constant to reduce the impact on the moisture content of the target clothes after drying. This ensures that the target weight range is determined more accurately based on the weight at the start of the drying process, the motor speed, and the correspondence between the moisture content of the target clothes and the drying weight range.

[0086] Based on the above implementation of the target operating parameters, after the controller determines the target operating parameters, the process of controlling the clothing processing settings to dry the target clothing according to the target operating parameters includes the following processing steps: (1) Control the drying heating tube to heat the target clothing according to the target heating time. (2) Control the motor to drive the target clothing to rotate according to the target speed. (3) Control the fan to rotate according to the target operating speed, and drive the air in the cylinder assembly to circulate at that speed. (4) Control the water inlet valve to control the water to be injected into the water inlet channel in a rhythmic manner according to the target timing.

[0087] Step S302: Based on the weight of the target garment when the drying program is started and the correspondence between the motor speed and the drying weight range, determine the target weight range corresponding to the first target weight and the target speed.

[0088] The drying weight range represents the weight range of the target garment when it reaches the preset drying level.

[0089] In this step, the garment processing equipment can determine the target weight range of the target garment after it reaches the target drying level based on the initial weight of the target garment and the correspondence between the motor speed and the drying weight range. In step S303, the weight detection device is controlled to detect the second target weight of the target garment during the drying process to obtain the second target weight.

[0090] In this step, the second target weight of the target garment is detected in real time during the drying process.

[0091] Step S304: When the second target weight is within the target weight range, stop executing the drying operation program.

[0092] The aforementioned second target weight being within the target weight range serves as a drying condition that satisfies the degree of drying.

[0093] In this step, the second target weight of the target garment during the drying process is acquired in real time, and it is determined whether the second target weight is within the target weight range. The drying process ends when the second target weight is within the target weight range.

[0094] Figure 3 The technical solution described above offers at least the following benefits: the garment processing equipment is equipped with different motor speeds and initial weights to determine the required weight range for the garments after drying; therefore, during the drying process, when the target garments reach the target weight range, it indicates that the garments are dried, and drying is stopped. This method of flexibly determining the drying time based on the target weight range ensures that the dried garments reach the target degree of dryness and prevents incomplete or over-drying due to various environmental factors (such as drying temperature and airflow speed) during the drying process.

[0095] Furthermore, drying methods in related technologies that use a temperature change value exceeding a preset temperature as the drying condition require additional temperature sensors to acquire the temperature change value. Therefore, compared to the aforementioned related technologies, the drying method in this application, which uses the target garment being within a target weight range during the drying process as the drying stop condition, eliminates the need for additional temperature sensors, reducing the manufacturing cost of the garment processing equipment, thereby lowering user operating costs and improving the user experience.

[0096] In one implementation, the controller of the garment processing equipment can determine the target weight range based on the target moisture content, the weight during drying operation, the motor speed, and the correspondence between the moisture content of the target garment and the drying weight range. Step S302 can be specifically implemented as follows:

[0097] Based on the weight of the target garment during the start-up drying process, the motor speed, and the correspondence between the moisture content of the target garment and the drying weight range, the first target weight, the target speed, and the target weight range corresponding to the target moisture content are determined.

[0098] The above-mentioned drying weight range can be understood as the weight range of the target garment after reaching a certain degree of drying.

[0099] It should be noted that for clothes of the same weight but different materials, after being dried under the same rotational speed of the motor, the moisture content of the clothes is basically the same. Therefore, when the rotational speed is fixed, if the initial weight of the target clothes and the target moisture content of the target clothes are determined, the weight of the target clothes after drying will be within a certain weight range.

[0100] Exemplarily, the corresponding relationship among the initial weight of the above-mentioned target clothes at the start of the drying operation, the rotational speed of the motor, and the moisture content of the target clothes and the drying weight range can be stored in the controller in the form of a table, and the storage form of the corresponding relationship can be as Figure 4 shown.

[0101] In some embodiments, the first target weight of the target clothes, also known as the load, such as target clothes of different weights, is simply referred to as different loads or loads of different weights. The moisture content can also be referred to as the moisture rate.

[0102] Here Figure 4 in the table, according to the actual test situation, it lists the weighing value ranges corresponding to different rotational speeds, different loads, and different moisture contents of the target clothes, that is, the drying weight range. In Figure 4 it is recorded that the second target weight is recorded as the moisture content weighing value Wb. The first target weight is the weighing value Wa before drying.

[0103] Figure 4 In, taking three different target rotational speeds and 3 different weights of loads at the same target rotational speed as examples, the corresponding relationship among the weight of the above-mentioned target clothes at the start of the drying operation, the rotational speed of the motor, and the moisture content of the target clothes and the drying weight range is described. Among them, n1, n2, and n3 respectively represent three different target rotational speeds.

[0104] Specifically, in the case of the target rotational speed n1, the initial weight Wa corresponds to three initial weight ranges, that is, Wa < W1, W1 ≤ Wa < W2, and Wa ≥ W2. In the case of the target rotational speed n2, the initial weight Wa corresponds to three initial weight ranges, that is, Wa < W1', W1' ≤ Wa < W2', and Wa ≥ W2'. In the case of the target rotational speed n3, the initial weight Wa corresponds to three initial weight ranges, that is, Wa < W1'', W1'' ≤ Wa < W2'', and Wa ≥ W2''.

[0105] In some examples, different drying grades correspond to different moisture contents, that is, the moisture content A% corresponding to the first drying grade; the moisture content B% corresponding to the second drying grade; the moisture content C% corresponding to the third drying grade.

[0106] Specifically, when the target rotational speed and the initial weight are fixed, the target weight range is determined according to different target water contents. If the target rotational speed belongs to n1 and it is determined that the initial weight Wa belongs to Wa < W1, then when the target water content is A%, the target weight range is Wb ≥ W1A; when the target water content is B%, the target weight range is W1B ≤ Wb < W1A; when the target water content is C%, the target weight range is W1C ≤ Wb < W1B.

[0107] In some other examples, first determine which one of the three target rotational speeds n1, n2, and n3 the target rotational speed belongs to; then according to the weighing value Wa before drying belonging to Figure 4 which one of the initial weight ranges formed by W1 to W2 or W1' to W2' or W1” to W2” in the table. Finally, based on Figure 4 the corresponding relationship in the shown chart, obtain the target weight range.

[0108] If the target rotational speed belongs to n1, it is determined that the initial weight Wa belongs to Wa < W1 and the target water content is A% corresponding to the first drying level, then the target weight range is Wb ≥ W1A.

[0109] Specifically, at the target rotational speed n1, for the water contents from A% to C% corresponding to the initial weight range formed by Wa between W1 and W2, the following target weight ranges are successively: 3 target weight ranges formed by W1A to W1C, 3 target weight ranges formed by W2A to W2C, and 3 target weight ranges formed by W3A to W3C.

[0110] At the target rotational speed n2, for the water contents from A% to C% corresponding to the initial weight range formed by Wa between W1' and W2', the following target weight ranges are successively: 3 target weight ranges formed by W1'A to W1'C, 3 target weight ranges formed by W2'A to W2'C, and 3 target weight ranges formed by W3'A to W3'C.

[0111] At the target rotational speed n3, for the water contents from A% to C% corresponding to the initial weight range formed by Wa between W1” and W2”, the following target weight ranges are successively: 3 target weight ranges formed by W1”A to W1”C, 3 target weight ranges formed by W2”A to W2”C, and 3 target weight ranges formed by W3”A to W3”C.

[0112] It should be noted that Figure 4 the table only lists the weighing values of different loads corresponding to n1, n2, and n3 rotational speeds at different water contents, but this application is not limited to setting parameters corresponding to three target rotational speeds, and parameters corresponding to multiple target rotational speeds can be set. Therefore, this application does not specifically limit the number of target rotational speeds.

[0113] Correspondingly, Figure 4 The table listed only includes parameters for three different weight loads for the same target rotational speed. However, this application is not limited to setting three different weight loads and can set multiple different weight loads. Therefore, this application does not specifically limit the number of weight loads.

[0114] Correspondingly, Figure 4 The table in the original document sets three weighing parameters for moisture content, ranging from A% to C%, for the same target rotational speed and the same weight load. However, this application is not limited to setting three parameters and can set multiple weighing value ranges corresponding to different moisture contents. Therefore, this application does not specifically limit the number of weight loads.

[0115] In this embodiment, the garment processing equipment pre-stores the weight of the target garment, the speed of the motor, and the correspondence between the moisture content of the target garment and the drying weight range when the drying process is started, so that the garment processing equipment can determine the target drying weight range based on the first target weight, the target speed, and the target moisture content.

[0116] Based on this implementation method, the user's needs for the degree of drying of clothes are taken into account, that is, the different users' needs for the moisture content of clothes after drying. Furthermore, different weight ranges are set for the moisture content of clothes with different degrees of drying, so as to ensure that the clothes after drying better meet the user's drying needs.

[0117] Based on the above implementation method of determining the target weight range according to the target moisture content, as a possible implementation method, the target moisture content can be determined in the following way: determine the target moisture content corresponding to the target drying level according to the target drying level corresponding to the drying operation program.

[0118] The target drying level mentioned above corresponds to the target degree of drying. This target drying level can be set by the user or preset by the garment processing equipment.

[0119] For example, different drying levels are pre-set in the garment processing equipment for users to select, and the user-selected drying level is used as the target drying level. Specifically, when the user starts the drying program, different drying levels, such as fully dry and semi-dry, are displayed to the user, who then selects the target drying level as needed. The drying level can be displayed on the garment processing equipment's display panel; alternatively, the user's terminal device can communicate with the garment processing equipment and display the drying level on the user's terminal device for selection.

[0120] In another example, if the user does not select a drying level, the pre-set drying level corresponding to the drying program will be used as the target drying level. Specifically, when the user starts the drying program, the preset drying level of the program can be directly set as the target drying level; alternatively, the washing mode of the target garment (e.g., cotton garment washing mode, wool garment washing mode, or fiber garment washing mode) can be detected first, and the drying level corresponding to the washing mode of the target garment can be set as the target drying level based on the correspondence between the washing mode and the drying level.

[0121] In this implementation, the garment processing equipment establishes a correspondence between drying levels and target moisture content, and the drying operation program is associated with the target drying level. Based on this implementation, the controller can determine the target moisture content based on the drying operation program.

[0122] As one implementation method, such as Figure 5 As shown, after performing step S303, the following steps can also be performed:

[0123] S501, when the second target weight is outside the target weight range, control the garment processing equipment to execute the drying operation program according to the target operating parameters.

[0124] It is understandable that during the drying process, if the drying conditions are not met, the second target weight is greater than or equal to the larger of the target weight range.

[0125] For example, the user selects a drying program with a target motor speed Rx of n1, i.e., Rx = n1. The user sets the drying level to H% moisture content. After the drying program runs for a time Ts, the garment is weighed, and the weight is recorded as Wa, which is the first target weight. A table shows that Wa corresponds to a target weight range of [W4W5]. During operation, the garment is weighed every time interval ΔTb, and the weight is recorded as the second target weight Wb. It is then determined whether Wb < W5. If Wb ≥ W5, the drying program continues until Wb < W5, meaning Wb meets the target weight drying range: W4 ≤ Wb < W5. At this point, the garment is considered dried, and the drying process ends.

[0126] In this embodiment, the failure to reach the target weight range is used as the execution condition for the drying procedure, thus ensuring the normal execution of the drying process.

[0127] As one implementation method, combined with Figure 3 ,like Figure 6As shown, after step S303 is completed, the end time of drying can be determined by reaching a time threshold. That is, when the execution time of the drying program by the clothing processing equipment reaches the time threshold, the drying program is stopped. Specifically, the following steps can be performed:

[0128] Step S301: When starting the garment processing equipment and executing the drying operation program according to the target operating parameters, determine the first target weight of the target garment and the target speed of the motor during the drying process.

[0129] Step S302: Based on the weight of the target garment when the drying program is started and the correspondence between the motor speed and the drying weight range, determine the target weight range corresponding to the first target weight and the target speed.

[0130] Step S303: Control the weight detection device to detect the second target weight of the target garment during the drying process to obtain the second target weight.

[0131] Step S601: Determine whether the execution time is greater than or equal to the time threshold. If yes, proceed to step S602; otherwise, proceed to step S603.

[0132] In step S601 above, the execution time is the time for the clothing processing equipment to execute the drying operation program.

[0133] Step S602: Stop the drying operation.

[0134] Step S603: Determine whether the second target weight is within the target weight range; if yes, proceed to step S602; if no, proceed to step S303.

[0135] For example, the time threshold for executing the drying operation program is TM1, the start time of drying is denoted as T1, and the execution time of the drying operation program during the drying process is denoted as Tn1. Then, the execution time of the drying operation program is Tn1-T1. When the execution time Tn1-T1≥TM1, the drying operation program ends regardless of whether the second target weight Wb has reached the drying condition, i.e., whether the second target weight Wb is within the target weight range.

[0136] Based on this, a time threshold is used to limit the maximum execution time of the drying operation program to prevent the drying process from continuing due to factors such as the water inlet valve not receiving water or the flow rate being too low.

[0137] As one implementation method, combined with Figure 3 ,like Figure 7As shown, the drying operation can be terminated by meeting the drying conditions multiple times consecutively. The drying condition is that the second target weight is within the target weight range. Then, the above step S304 can be achieved through the following steps.

[0138] Step S701: Obtain the second target weight for a consecutive preset number of preset periods.

[0139] The second target weight is obtained according to a preset cycle.

[0140] Step S702: When the second target weight is within the target weight range for each of the preset preset cycles, stop executing the drying operation program.

[0141] For example, taking a preset number of N1 as an example, if the drying conditions are detected for N1 consecutive time intervals ΔTb, it is determined that the target clothing has been dried, and the drying process ends.

[0142] Another example is that at the beginning of the drying process, the system checks whether Wa-Wb≤Wc is satisfied every N2 consecutive time intervals ΔTb. If Wa-Wb≤Wc is checked every N3 consecutive times, the drying process ends; otherwise, the drying process continues.

[0143] Based on this, the drying condition is terminated when the drying condition is reached a preset number of times. This ensures that the target clothing meets the drying condition multiple times at the end of the drying process, thus ensuring that the target clothing is in a stable drying state and avoiding the erroneous operation of mistakenly judging that the target clothing meets the drying condition in one instance.

[0144] As one implementation method, in order to ensure that the first target weight matches the weight in the corresponding relationship, if the target clothing is too wet, the following steps can be performed before executing step S301, that is, before determining the first target weight of the target clothing: dehydrating the target clothing.

[0145] It should be noted that for situations where the target garment is excessively damp, the dehydration process could be pre-set by the user who already knows the garment is too damp, or the garment processing equipment could incorporate the dehydration step into the drying process. Alternatively, when starting the drying process, the garment processing equipment could first detect the moisture content of the target garment; if the moisture content is too high, it could first execute the dehydration process, and then execute the drying process.

[0146] In addition, during the process of washing clothes and then transitioning to drying clothes, a dehydration process is usually performed.

[0147] For example, the drying program defaults to a dehydration process. After starting the drying program, it first identifies the target motor speed set in the user-selected drying program, denoted as Rx. Then, it performs dehydration for a certain period of time, denoted as Ts. After dehydration, it weighs the components before drying, and the weight is recorded as in the example above, denoted as Wa. Then, it controls the heating element, fan, water inlet valve, and other components to execute the drying process according to the software settings, while simultaneously timing the start of drying, denoted as T1.

[0148] Based on this, the impact of excessive moisture in the target clothing on the drying process is taken into consideration. If the target clothing is completely soaked, directly drying the wet clothing may result in excessively long drying time or failure to dry at all. Therefore, the target clothing is first dehydrated before starting the drying function to ensure drying efficiency.
