Description

Technical Field

[0001] This invention belongs to the field of household appliance technology. Specifically, it relates to a control method for a garment processing device and a garment processing device using the above-mentioned control method. Background Technology

[0002] In existing technology, drum washing machines are basically top-draining. After each wash, some water will remain in the drum. When users buy new clothes, they only want to rinse them with water, or clothes that have been stored for a while, they only want to rinse them with water. However, the normal washing time is relatively long, and usually the water in the outer drum is filled to a certain height before the clothes are soaked in water for washing. This washing method without detergent may cause the clothes to become contaminated.

[0003] Chinese Patent Application No. CN200910139869.3 discloses a program control method for a gentle wash cycle in a washing machine, including water intake, washing, rinsing, and spin-drying programs. The method is characterized by the following steps: Step 1: The water inlet valve is powered on and the water intake stops when the set water level is reached. The motor starts working, washing for 2-4 minutes, stopping for 2-4 minutes, and repeating this cycle 2-4 times. Step 2: The actuator 1 is powered on, the drain valve is opened, and after drainage, the water inlet valve is powered on again, allowing water to enter and wash simultaneously. Step 1: Drain the water. The motor runs the washing program for 3-5 minutes, the water inlet valve is closed, the actuator 2 is powered on, the clutch spring lever is pulled, the pawl is opened, and the motor rotates clockwise at high speed for 3-6 seconds, pausing for 3-6 seconds, repeating this cycle 2-4 times. Then, spin-dry for 2-4 minutes. Step 2: De-energize actuator 1, the drain valve resets, and simultaneously energize the water inlet valve to open the water inlet. Once the set water level is reached, stop the water inlet, and the washing machine motor runs for 2-4 minutes, pausing for 2-4 minutes, repeating this cycle 1-3 times. Step 3: energize actuator 1, pull the drain valve, draining is complete, actuator 2 is powered on, the clutch spring lever is pulled, the pawl is opened, and the motor rotates clockwise at high speed for 3-6 seconds, pausing for 3-6 seconds, repeating this cycle 3-6 seconds. The program ends.

[0004] The above solution first involves thoroughly wetting and soaking the clothes in step one, washing while soaking to facilitate the removal of dirt. Step two involves a simultaneous water intake, washing, and drainage process to promptly remove the dirt from the washing machine, ensuring the clothes are thoroughly cleaned. Step one of this solution, soaking and using detergent to clean the clothes, not only requires an additional rinsing stage to remove detergent residue, but also makes the detergent prone to adhering to the drum wall and accumulating dirt that is difficult to rinse off. Especially for new clothes with minimal dirt, only surface dust or odor, this solution requires a second rinsing after detergent washing to remove the detergent, wasting water and making the washing process more complex and time-consuming.

[0005] In view of this, the present invention is hereby proposed. Summary of the Invention

[0006] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a control method for a clothing processing device. The present invention aims to solve the problem that the prior art does not use detergent, but only uses water to rinse clothes, so as to avoid the clothes being contaminated by residual washing water in the clothing processing device; in particular, it provides a control method for a clothing processing device to achieve the purpose of cleaning new clothes.

[0007] To address the aforementioned technical problems, the first aspect of this application discloses...

[0008] A control method for a garment processing device, the garment processing device having a spray rinsing program; the spray rinsing program is as follows: the water inlet is turned on, and the water flow is directly sprayed onto the garments contained in the inner drum; during the spray rinsing process, the water level in the outer drum of the garment processing device is always lower than the bottom of the inner drum.

[0009] With the above design, new clothes or clothes that have been stored for a long time are rinsed directly by spraying clean water. During the spray rinsing process, the water level of the clothes treatment equipment is always lower than the inner drum, eliminating the need for soaking. This prevents the clothes from being contaminated by residual washing water in the clothes treatment equipment, thus achieving the purpose of rinsing the clothes. At the same time, it eliminates the need for detergent and rinsing, making the spray rinsing process simpler, faster, and more water and energy-saving.

[0010] Furthermore, before starting the water inlet, the process includes closing the drain pipe of the outer tub; the process of directly spraying the inlet water onto the clothes in the inner tub also includes determining whether the water level in the outer tub of the clothing processing equipment has reached a first preset water level; if so, start the drainage; otherwise, continue to close the drainage.

[0011] Through the above design, the present invention starts draining only when the water level in the clothing processing equipment reaches the first preset water level, rather than automatically starting draining when the spray rinsing program begins. This saves some electricity and allows a certain amount of water to accumulate between the outer and inner drums. By heating the water between the outer and inner drums, the temperature of the inner drum is increased or steam is generated, thereby improving the cleaning effect on the clothes or achieving sterilization and disinfection.

[0012] Further, determining whether the water level in the outer drum of the clothing processing equipment has reached the first preset water level includes detecting whether the water level frequency value in the outer drum of the clothing processing equipment is less than or equal to the first preset value. If the water level frequency value is less than or equal to the first preset value, then the water level in the outer drum of the clothing processing equipment has reached the first preset water level; otherwise, the water level in the outer drum of the clothing processing equipment has not reached the first preset water level.

[0013] Through the above design, this application determines the water level by detecting the water level frequency value in the clothing processing equipment. The water level determination is accurate and simple. Furthermore, it determines whether the water level frequency value in the clothing processing equipment is less than or equal to the first preset value for more than a set time. If it exceeds the set time, it indicates that the water on the clothing is in a supersaturated state and begins to drip, and the water level in the clothing processing equipment continues to change.

[0014] Furthermore, it also includes adjusting the drainage volume according to the water level in the outer drum of the garment processing equipment; detecting whether the water level in the outer drum of the garment processing equipment has reached the first preset water level; if the water level in the outer drum of the garment processing equipment has reached the first preset water level, starting drainage and setting the drainage volume to be greater than the inflow volume; detecting whether the water level in the garment processing equipment has reached the second preset water level; if the water level in the garment processing equipment has reached the second preset water level, starting drainage and setting the drainage volume to be less than the inflow volume; the first preset water level is higher than the second preset water level and lower than the bottom height of the inner drum.

[0015] Through the above design, by dynamically adjusting the drainage volume, a certain amount of washing water is always accumulated between the inner and outer drums, avoiding dry burning of the clothes handling equipment and causing it to malfunction.

[0016] Furthermore, it also includes detecting the height of the clothes in the inner drum and adjusting the spray rinsing method according to the detected height of the clothes.

[0017] Through the above design, the height of the clothes varies depending on the amount of clothing. As the clothes rotate in the inner drum, the spray water must always keep rinsing the clothes. Combining the movement patterns of clothes at different heights, this invention provides different spray rinsing methods.

[0018] Furthermore, the method of adjusting the spray rinsing mode according to the height of the detected clothing includes the following mode 1: the inner drum is stationary, and the height of the clothing in the inner drum is detected by using the stationary inner drum; when the height of the detected clothing is less than or equal to 1 / 3 of the height of the inner drum, the rinsing mode of the first sprayer or the second sprayer at the top of the inner drum is activated to spray water onto the clothing; when the height of the detected clothing is higher than 1 / 3 of the height of the inner drum but less than or equal to 2 / 3 of the height of the inner drum, the rinsing mode of the first sprayer and the second sprayer at the top of the inner drum is activated to spray water onto the clothing; when the height of the detected clothing is higher than 2 / 3 of the height of the inner drum, the rinsing mode of the first sprayer, the second sprayer at the top of the inner drum and the third sprayer and the fourth sprayer on both sides of the inner drum are activated to spray water onto the clothing.

[0019] With the above design, when the inner drum is stationary, different spraying methods are used for clothes of different heights when spraying clothes, ensuring that the spray water is sprayed onto the clothes, achieving the purpose of cleaning clothes, and also saving water resources.

[0020] Furthermore, the method of adjusting the spray rinsing mode according to the height of the detected clothing includes a second method: the inner drum rotates in a single direction at a set speed, and the clothing inside the inner drum rotates along with the wall; the thickness of the clothing inside the rotating inner drum is detected; when the thickness of the detected clothing inside the rotating inner drum is less than or equal to 1 / 3 of the inner drum radius, the rinsing mode of the third or fourth sprayer on both sides of the inner drum is activated to spray water onto the clothing; when the thickness of the detected clothing inside the rotating inner drum is greater than 1 / 3 of the inner drum radius but less than or equal to 2 / 3 of the inner drum radius, the rinsing mode of the first or second sprayer at the top of the inner drum is activated, and the rinsing mode of the third or fourth sprayer on the side of the inner drum is activated simultaneously to spray water onto the clothing; when the thickness of the detected clothing inside the rotating inner drum is greater than 2 / 3 of the inner drum radius, the rinsing mode of the first and second sprayers at the top of the inner drum and the third and fourth sprayers on both sides of the inner drum are activated to spray water onto the clothing.

[0021] With the above design, the inner drum rotates, causing the clothes to rise to a certain height and then fall. When there are few clothes, the clothes mainly move between the bottom of the inner drum and the raised position. When the drum is full of clothes, there are more clothes, and the height will decrease after they are wet. However, since the clothes are not soaked in the washing water, a larger water flow is required to spray and rinse the clothes to ensure that they are fully sprayed.

[0022] Furthermore, during the spray rinsing process, the inner cylinder alternates between rotating for a certain period of time and remaining stationary for a certain period of time. When the inner cylinder is stationary, the rinsing mode is adjusted using mode one; when the inner cylinder is rotating, the rinsing mode is adjusted using mode two; when the inner cylinder changes from stationary to rotating, or from rotating to stationary, the rinsing mode is the preset setting mode.

[0023] By adjusting the spray pattern according to the inner drum condition, the spray water can be sprayed onto the clothes as much as possible, avoiding water from flowing directly out of the inner drum holes and wasting water resources.

[0024] Furthermore, during the spray rinsing process, the humidity at the front and rear of the outer cylinder along the axial direction is also detected separately; if the difference between the detected humidity values ​​at the front and rear of the outer cylinder along the axial direction is greater than a set threshold, an alarm will be triggered; if it is less than the set threshold, no alarm will be triggered.

[0025] With the above design, when there are many clothes in the inner drum, the spray water flow is blocked and cannot be sprayed directly to the bottom of the inner drum. This results in uneven wetting of the clothes at the bottom of the inner drum and fails to achieve the purpose of spray rinsing. In this case, the clothes can be automatically evenly wetted by the clothes treatment equipment, or the clothes can be manually adjusted so that the parts that are to be sprayed can also be rinsed.

[0026] A second aspect of this application also provides a garment processing apparatus for performing the garment processing method as described above, the garment processing apparatus comprising an outer cylinder and an inner cylinder rotatable about an axis inside the outer cylinder.

[0027] Furthermore, at least one sprayer is installed on the outer drum. The sprayer is connected to the water inlet structure of the washing machine and sprays water toward the inner drum to spray the water into the inner drum of the washing machine. The sprayer is installed on the outer drum of the washing machine or at the window gasket and sprays water into the inner drum from the inner drum opening, so that the sprayed water is directly sprayed onto the clothes in the inner drum.

[0028] Furthermore, the top of the inner drum is equipped with a first sprayer and a second sprayer, and the left and right sides of the inner drum are respectively equipped with a third sprayer and a fourth sprayer; each sprayer is connected to the water inlet structure of the washing machine, and a control valve is provided on the connecting pipe to control the connection of one or a combination of sprayers to the water inlet structure, thereby achieving the effect of controllable selection or combination of sprayers to spray water into the inner drum of the washing machine.

[0029] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art.

[0030] 1. This invention uses only clean water and employs a spray rinsing method to wash clothes. To avoid contact between the clothes and residual washing water in the clothes processing equipment, the water level in the clothes processing equipment is always lower than the inner drum, ensuring that the clothes are always rinsed with clean water. This eliminates the need for detergent and rinsing procedures, making it more energy-efficient and water-saving.

[0031] 2. This invention does not use detergent, and can also avoid detergent adhering to the drum wall and causing pollution. When rinsing clothes with water, it can also play a role in self-cleaning the bottom of the drum.

[0032] 3. This invention first stores water between the inner and outer drums. When the water level reaches the first preset water level, the drainage is turned on, realizing a process of rinsing, washing and draining at the same time. It can also heat the washing water between the inner and outer drums to improve the cleaning efficiency of clothes.

[0033] 4. In order to ensure that the water flow reaches the clothes during the spray rinsing process, the present invention adopts different spraying methods based on the height of the clothes and the movement pattern of the clothes in the inner drum. On the one hand, it saves water resources, and on the other hand, it allows the clothes to be fully sprayed and rinsed.

[0034] The specific embodiments of the present invention will now be described in further detail with reference to the accompanying drawings. Attached Figure Description

[0040] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0041] In the description of this invention, it should be noted that the terms "upper", "lower", "left", "right", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0042] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0043] The present invention will be further described in detail below with reference to the embodiments.

[0044] like Figures 1 to 6 As shown, the present invention proposes a clothing treatment method, including a spray rinsing program, turning on the water inlet, spraying the water directly onto the clothing, and ensuring that the water level in the clothing treatment equipment is always lower than the bottom of the inner drum 2 during the spray rinsing process.

[0045] This invention does not use detergent; it uses clean water to wash new or long-stored clothes, removing dust and odors. To avoid secondary contamination of clothes by contact with residual washing water inside the garment processing equipment, this invention employs a spray rinsing method, ensuring the water level in the garment processing equipment remains below the inner drum 2 to achieve the purpose of cleaning clothes. It also eliminates the need for detergent, omitting the rinsing process, saving washing time and water resources, and avoiding the problem of detergent adhering to the drum wall and being difficult to clean. Rinsing clothes with clean water also helps clean the drum wall, enhancing the self-cleaning function of the garment processing equipment.

[0046] Furthermore, such as Figure 2 As shown, the process before starting the water inlet also includes:

[0047] Turn off the drain;

[0048] After the incoming water is sprayed directly onto the clothes, the process also includes determining whether the water level in the clothing treatment equipment has reached the first preset water level. If so, the drainage is turned on; otherwise, the drainage is turned off.

[0049] Before water enters the garment, the drain is turned off. When the water level in the garment processing equipment reaches the first preset water level, the drain is turned on. The time for this spray rinsing is calculated from the time the drain is turned on. At this time, the inner drum 2 rotates. The rotation speed of the inner drum 2 is 20-200 rpm. The inner drum 2 can also rotate when the spray rinsing program is started. This is not limited here.

[0050] Preferably, the spray rinsing program is set to a washing time of 1-30 minutes. The user can set the time of the spray rinsing program according to actual needs, but the overall washing time is shorter than that of washing with detergent and rinsing, and it saves more water.

[0051] This invention does not simultaneously open the water inlet and outlet. Firstly, delaying the drainage start time saves energy. Secondly, it allows a certain amount of water to accumulate in the garment processing equipment. By heating this accumulated water, the temperature of the inner drum 2 is increased, improving the cleaning efficiency. When the accumulated water is heated to generate steam, it can also sterilize and disinfect the clothes, removing harmful substances such as formaldehyde. This invention can control the water volume between the inner and outer drums by setting the drainage time, which will not be elaborated further here.

[0052] Furthermore, determining whether the water level in the clothing processing equipment has reached the first preset water level includes detecting whether the water level frequency value in the clothing processing equipment is less than or equal to the first preset value. If the water level frequency value is less than or equal to the first preset value, then the water level in the clothing processing equipment has reached the first preset water level; otherwise, the water level in the clothing processing equipment has not reached the first preset water level.

[0053] Preferably, the detection device detects whether the water level frequency value in the clothing processing device is less than or equal to a first preset value for a set time. If the water level frequency value is less than or equal to the first preset value for a set time, then the water level in the clothing processing device has reached the first preset water level; otherwise, the water level in the clothing processing device has not reached the first preset water level.

[0054] Alternatively, the set time is 5 seconds.

[0055] This invention uses the frequency value of the water level in the garment processing equipment to determine the water level. The detection method is simple and the results are accurate. Furthermore, if the detected water level frequency value in the garment processing equipment is less than or equal to a first preset value for a set time, it proves that the water used to soak the clothes is supersaturated and dripping begins. Therefore, the difference in water level height detected by the water level sensor is constantly changing. At this time, continuous drainage should be maintained so that the clothes never come into contact with the washing water in the inner drum 2. This invention can control the drainage volume by setting the drainage time. Those skilled in the art can set it according to actual conditions, which will not be elaborated here.

[0056] Furthermore, it also includes adjusting the drainage volume according to the water level in the clothing processing equipment, detecting whether the water level in the clothing processing equipment has reached the first preset water level, and if the water level in the clothing processing equipment has reached the first preset water level, starting the drainage and setting the drainage volume to be greater than the inflow volume.

[0057] Detect whether the water level in the clothing processing equipment has reached the second preset water level. If the water level in the clothing processing equipment has reached the second preset water level, set the drainage volume to be less than the inflow volume.

[0058] Preferably, the first preset water level is higher than the second preset water level.

[0059] The first water level is slightly lower than the bottom of the inner drum, and the second water level is equal to or higher than the height where the heater is installed. This ensures that there is always water between the inner and outer drums, preventing dry burning and damage to the clothing processing equipment. By dynamically adjusting the drainage in conjunction with the water inlet, this invention can further ensure that there is always washing water between the inner and outer drums.

[0060] Furthermore, the spray rinsing process is preceded by a drainage process to remove residual washing water from the garment processing equipment.

[0061] Although the present invention can drain the residual washing water in the clothing treatment equipment by setting a drainage program, detergent dirt will still adhere to the drum wall. When washing new clothes, if the clothes are soaked, the detergent dirt will inevitably dissolve in the water and come into contact with the clothes. In order to avoid the new clothes coming into contact with detergent dirt, the water level in the clothing treatment equipment should be controlled not to be higher than the inner drum 2.

[0062] In the spray rinsing process of the present invention, in order to keep the water flow spraying onto the clothes, the inner drum 2 rotates continuously, ensuring that the flowing water rinses the rotating clothes, which can remove lint, dust and other debris from the clothes in time, thus meeting the user's needs for clean clothes.

[0063] Furthermore, such as Figures 3 to 6 As shown, it also includes determining the height of the clothing and adjusting the spray rinsing method according to the height of the clothing.

[0064] This invention provides different spray rinsing methods for clothing of different heights, so as to save water resources while ensuring that water is sprayed onto the clothing, and make full use of the spray water to achieve the purpose of cleaning clothes.

[0065] Furthermore, the determination of clothing height and adjustment of the spray rinsing method based on clothing height includes Method 1, which is detailed below:

[0066] With the inner drum 2 stationary, the height of the clothes inside the inner drum is measured;

[0067] When the height of the clothes is less than or equal to 1 / 3 of the inner drum height, activate the rinsing mode of either the first sprayer 30 or the second sprayer 31 at the top of the inner drum 2 to spray water onto the clothes. Figure 3 As shown;

[0068] When the height of the clothes is higher than 1 / 3 but less than or equal to 2 / 3 of the inner drum height, the first sprayer 30 and the second sprayer 31 at the top of the inner drum 2 are activated to spray water onto the clothes. Figure 4 As shown;

[0069] When the height of the clothes is higher than 2 / 3 of the height of the inner drum, the washing mode is activated by turning on the first sprayer 30, the second sprayer 31 at the top of the inner drum 2 and the third sprayer 32 and the fourth sprayer 33 on both sides, spraying water onto the clothes.

[0070] As is well known, simply airing out newly purchased or seasonal clothing is insufficient to completely remove dust or odors. For lightweight fabrics with a small amount of laundry, a spray rinse requires only a small water flow. Conversely, for heavier fabrics with a larger amount of laundry, a spray rinse obviously requires a larger water flow. Therefore, this invention addresses the height of the clothing inside the inner drum 2. When the clothing height is less than or equal to one-third of the inner drum 2's height, it indicates a small amount of clothing. When the inner drum 2 is stationary, the clothing tends to concentrate at the radial bottom. Using a top-mounted single-spray system ensures that water is sprayed directly onto the clothing, preventing water from flowing out of the inner drum 2's holes and wasting water. Specifically, the first and second sprayers form the first and second spray patterns, respectively, spraying water directly from the top of the inner drum onto the clothing at the bottom. Two sprayers are symmetrically distributed radially along the inner drum opening. The first and second spraying methods correspond to the first and second spraying areas, respectively. The first or second spraying area must at least cover the bottom of the inner drum; the specific coverage area can be adjusted according to actual needs. The first and second spraying areas are slightly offset from the areas where the first and second sprayers are located. Similarly, when the height of the clothes is higher than 1 / 3 and less than or equal to 2 / 3 of the inner drum height, the amount of clothes is moderate. A top-dual spraying method is used, where the first and second sprayers simultaneously spray and rinse the clothes, ensuring sufficient water flow onto the clothes and enough water to soak all the clothes, achieving the effect of spraying, rinsing, and draining simultaneously. When the clothes fill the entire inner drum 2, and the height decreases after soaking, to prevent clothes near the inner drum opening from blocking clothes at the bottom of the inner drum 2, the water flow should be increased to rinse the clothes, ensuring that all clothes are rinsed. When there are more clothes and more spraying methods are activated, it is best to simultaneously increase the spray speed to enhance the rinsing effect.

[0071] Furthermore, the determination of clothing height and adjustment of the spray rinsing method based on clothing height includes a second method, which is detailed below.

[0072] The inner drum 2 rotates, and the clothes inside rotate together with it, adhering to the wall; the thickness of the clothes inside the rotating inner drum is measured.

[0073] When the thickness of the clothing is less than or equal to 1 / 3 of the inner drum radius, the third sprayer 32 or the fourth sprayer 33 on the radial side of the inner drum 2 activates a spray rinsing mode, spraying water onto the clothing. Figure 5 As shown;

[0074] When the thickness of the clothing is greater than 1 / 3 of the inner drum radius but less than or equal to 2 / 3 of the inner drum radius, the first sprayer 30 or the second sprayer 31 at the top of the inner drum 2, and the third sprayer 32 or the fourth sprayer 33 on the radial side of the inner drum 2, will activate the rinsing mode to spray water onto the clothing. Figure 6 As shown;

[0075] When the thickness of the clothing is higher than 2 / 3 of the inner drum radius, the rinsing mode of the top first sprayer 30, the second sprayer 31, and the side third sprayers 32 and the fourth sprayer 33 is activated to spray water onto the clothing.

[0076] In this embodiment of the invention, in the second method described above, when the clothes at the bottom of the inner drum rotate to the left along with the inner drum, the fourth sprayer 33 on the left side of the inner drum is turned on accordingly; while when the clothes at the bottom of the inner drum rotate to the right along with the inner drum, the third sprayer 32 on the right side of the inner drum is turned on accordingly, so as to improve the spray rinsing effect.

[0077] After clothes are put into the clothing processing device of the present invention, the spray washing program is started. When the inner drum 2 is stationary or rotating, the clothes are in different motion states. However, after the rotation speed of the inner drum 2 reaches the set value, the clothes will be subjected to centrifugal force and rotate against the drum wall, so that the maximum distance between the clothes and the inner drum wall, i.e. the thickness of the clothes, is a fixed value. Under the premise of user input or automatic determination of the material of the clothes by the washing machine, the amount of clothes in the drum can be obtained by the detection of the thickness of the clothes. When the thickness of the clothing is less than or equal to 1 / 3 of the inner drum's radius, the amount of clothing is relatively small. When the inner drum 2 rotates, the clothing moves radially from the bottom of the inner drum 2 to a roughly horizontal position and then falls back to the bottom of the inner drum 2. This cycle repeats. At this time, the clothing moves in a 90° fan-shaped area at the bottom of the drum. Therefore, turning on the spray in this direction ensures that the water is sprayed onto the clothing and is not wasted from the inner drum holes, making full use of the spray water and avoiding waste. Specifically, the third and fourth sprayers form the third and fourth spray patterns, spraying water onto the clothing from the upper horizontal positions on both sides of the inner drum. The third and fourth spray patterns correspond to the third and fourth spray areas. The third spray area covers the side where the third sprayer is located and the bottom area of ​​the inner drum, and the fourth spray area covers the side where the fourth sprayer is located and the bottom area of ​​the inner drum. The inner drum rotates counterclockwise. When the inner drum rotates clockwise, a third spray method is used, and a fourth spray method is used when the inner drum rotates counterclockwise. Similarly, when the amount of laundry increases to a height that is more than 1 / 3 but less than or equal to 2 / 3 of the inner drum radius, the inner drum rotates counterclockwise, and the first spray method and the third spray method on the same side as the first sprayer are used to ensure the laundry is thoroughly cleaned. When the inner drum is full of laundry, the focus is not obvious. To ensure thorough cleaning, the water intake is increased, and a combination of the first to fourth spray methods is used. The spray rinsing program of this invention can be set with a fixed washing time. By adjusting the spray method, even with a large amount of laundry, thorough cleaning can be achieved. The spray rinsing program itself is a convenient and quick washing program, as it does not involve rinsing. Therefore, adjusting the spray method to enhance the washing effect for different amounts of laundry is convenient and feasible.

[0078] In this embodiment of the invention, during the spray rinsing process, the inner cylinder alternates between rotating for a certain period of time and remaining stationary for a certain period of time.

[0079] During the rotation of the inner drum over a certain period of time, there are any one or a combination of acceleration phase, low-speed uniform speed phase, high-speed uniform speed phase, and deceleration phase. During the high-speed uniform speed phase, the rotation speed of the inner drum is greater than the set value, and the clothes inside the drum rotate together with the inner drum against the wall. The spraying mode is adjusted using the above method two. In other phases, the spraying mode determined in the previous high-speed uniform speed phase is used.

[0080] During the period when the inner drum is stationary, there are acceleration phase, stationary phase and deceleration phase. During the stationary phase, the inner drum rotates at 0 and the clothes inside the drum are stationary along with the inner drum. The spray mode is adjusted in this way. In other phases, the spray mode determined in the previous stationary phase is used.

[0081] In this embodiment of the invention, the following settings can also be made: when the inner drum 2 changes from stationary to rotating or from rotating to stationary, the corresponding spraying mode is dynamically adjusted to the set spraying mode; the set spraying mode is a preset spraying mode that is manually selected by the user before the washing machine starts working or automatically selected by the washing machine.

[0082] This invention provides different spray rinsing methods for different movement states of clothing. When the movement state of clothing changes dynamically, the spray rinsing method should also be adjusted accordingly to make full use of the spray water flow.

[0083] Furthermore, it also includes detecting the humidity at the front and rear of the outer cylinder 1 along the axis, and determining whether to alarm based on the difference in humidity at the front and rear of the outer cylinder 1 along the axis. If the difference in humidity at the front and rear of the outer cylinder 1 along the axis is greater than a set threshold, an alarm will be triggered; otherwise, no alarm will be triggered.

[0084] When there is a large amount of laundry, the spray washing program may spray and wash clothes closer to the water inlet more effectively. The clothes cannot be automatically tumbled or soaked. Clothes located at the bottom of the inner drum 2 may not receive spray washing. This causes the humidity in the inner drum 2 to vary. By detecting the humidity difference between the drum opening and the bottom of the inner drum 2, it can be determined whether the clothes are fully soaked. If the difference is large, it means that the clothes at the bottom of the drum 2 have not received sufficient spray washing. You can manually tumble the clothes by triggering an alarm or wash them separately in multiple sessions to ensure that all clothes are spray washed.
