[0002] The present invention relates to the technical field of washing equipment, and more particularly to a drum-type washing machine, an isolated washing control method for washing equipment, and a washing equipment. [Background technology]

[0003] Washing machines are common household laundry washing machines, and are mainly classified into pulsator washing machines and drum washing machines depending on the washing mode. In the washing mode of a conventional drum washing machine, water is first supplied between the inner and outer tubs so that the water level is higher than the inner tub and the clothes are immersed in the water, and then the inner tub is rotated to "batter" the clothes to wash them. When the washing machine is used for a long time, bacteria inevitably grow between the inner and outer tubs, which can cause cross-contamination of the clothes when the user uses the washing machine again, which is unhealthy.

[0004] Therefore, there is a need in the art for new technical solutions to solve the above problems. Summary of the Invention [Problem to be solved by the invention]

[0005] First technical proposal: CN202211543213.X

[0006] The present invention aims to solve the above-mentioned technical problem, namely, the problem that bacteria between the inner and outer tubs may adhere to clothes in the washing mode of a conventional drum-type washing machine, causing secondary contamination of the clothes. [Means for solving the problem]

[0007] The present invention provides an isolated washing control method for a drum-type washing machine, the drum-type washing machine including an inner tub, an outer tub, and a spray device, the inner tub being rotatably disposed within the outer tub, the inner tub being used to accommodate clothes to be washed, a clearance cavity being formed between the inner tub and the outer tub, the spray device being disposed so as to be able to spray into the inner tub, the control method including the steps of: S1, controlling the spray device to alternately spray water and / or detergent onto the clothes to be washed in the inner tub and controlling the inner tub to rotate, thereby washing the clothes to be washed in the inner tub with running water; S2, when the spray device is activated, acquiring an actual water level in the clearance cavity; and S3, when the actual water level is higher than a preset water level, controlling the clearance cavity to drain water so that the water in the clearance cavity does not always come into contact with the inner tub.

[0008] When the above technical solution is adopted, the spray device sprays directly onto the clothes to be washed in the inner tub during the washing and rinsing stages, so that the sprayed water and / or detergent first enters the inner tub and comes into contact with the clothes to be washed, then enters the gap cavity, and finally exits the gap cavity. This ensures that the water and / or detergent sprayed onto the clothes to be washed is always clean and not reused. At the same time, the water in the gap cavity does not constantly come into contact with the inner tub, and as the inner tub rotates, the water in the gap cavity does not re-enter the inner tub as it rotates, preventing bacteria in the gap cavity from being carried into the inner tub and adhering to the clothes to be washed, thereby preventing secondary contamination of the clothes. Furthermore, because the water in the gap cavity does not constantly come into contact with the inner tub, the inner tub does not need to overcome resistance caused by contact with water as it rotates, thereby reducing power consumption compared to conventional drum-type washing machines.

[0085] First technical proposal: CN202211543213.X, Figures 1 to 4, first embodiment.

[0086] First Example First, referring to Fig. 1, Fig. 1 is a structural schematic diagram of a drum-type washing machine of the present invention. As shown in Fig. 1, the drum-type washing machine of the present invention includes an inner tub 1, an outer tub 2, and a spray device (not shown), the inner tub 1 is rotatably installed in the outer tub 2, the inner tub 1 is used to store clothes to be washed, a clearance cavity (not shown in Fig. 1) is formed between the inner tub 1 and the outer tub 2, a window packing 3 is installed at the open end of the front structure of the outer tub 2, and the spray device is attached to the window packing 3 and installed so as to be able to spray inside the inner tub 1.

[0087] 2, which is a flowchart showing the main steps of the method for controlling the isolated washing of a drum washing machine according to the present invention, which is used in the washing and rinsing stages of the drum washing machine. As shown in FIG. 3, the method for controlling the isolated washing of a drum washing machine according to the present invention includes the following steps:

[0088] Step S1: The spray device is controlled to spray water and / or detergent onto the clothes to be washed in the inner tub 1, and the inner tub 1 is controlled to rotate, alternately washing the clothes to be washed in the inner tub 1 with running water.

[0089] Step S2: When the spray device is started, the actual water level height in the gap cavity is obtained.

[0090] Step S3: If the actual water level is higher than the preset water level, the gap cavity is controlled to drain so that the water in the gap cavity does not always contact the inner tank 1.

[0091] Here, a water level sensor (not shown) is provided in the gap cavity to detect the actual water level in the gap cavity.

[0092] During the washing and rinsing stages, the spray device sprays water and / or detergent directly onto the clothes in inner tub 1, first entering the clothes and then entering the gap cavity, and finally exiting the gap cavity. This ensures that the water and / or detergent sprayed onto the clothes is always clean and not reused. At the same time, the water in the gap cavity does not always come into contact with inner tub 1, and as inner tub 1 rotates, the water does not re-enter the inner tub 1, preventing bacteria in the gap cavity from entering the inner tub 1 and adhering to the clothes, thereby preventing cross-contamination of the clothes. Furthermore, because the water in the gap cavity does not always come into contact with inner tub 1, inner tub 1 does not need to overcome resistance from contact with water during rotation, resulting in lower power consumption compared to conventional drum-type washing machines.

[0093] Furthermore, by adopting the spray mode to wash and rinse clothes, water and / or detergent can be sprayed more evenly onto the clothes, ensuring the washing and rinsing effect of the clothes while also saving water.

[0094] 3, which is a flowchart showing the specific steps of step S1 of the washing stage in the drum-type washing machine control method of the present invention. As shown in FIG. 3, step S1 specifically includes the following steps:

[0095] Step S11: The spray device is controlled to spray water onto the clothes to be washed in the inner tub 1.

[0096] Step S12: The inner tank 1 is controlled to rotate back and forth.

[0097] In step S13, the spray device is controlled to spray detergent onto the laundry to be washed in the inner tub 1.

[0098] In the washing stage, first, steps S11 and S12 are repeated multiple times to soak the laundry to be washed, and then steps S12 and S13 are repeated multiple times to apply the detergent to the laundry to be washed.

[0099] Specifically, during one execution of steps S11 and S12, the spray device is first controlled to spray water onto the clothes to be washed in the inner tub 1, and then the inner tub 1 is controlled to rotate back and forth, and this cycle is repeated multiple times until the preset amount of water sprayed and the preset number of sprays are reached. Similarly, during one execution of steps S12 and S13, the spray device is first controlled to spray detergent onto the clothes to be washed in the inner tub 1, and then the inner tub 1 is controlled to rotate back and forth, and this cycle is repeated multiple times until the preset amount of detergent sprayed and the preset number of sprays are reached.

[0100] In the above steps, by controlling the spray and the rotation of the inner tub 1 to alternate, the clothes to be washed are dispersed when the inner tub 1 rotates, preventing the clothes from overlapping, and allowing the water and / or detergent to be sprayed more evenly onto the clothes to be washed. Meanwhile, a dotted water supply method is formed, which ensures the accuracy of the water supply level entering the gap cavity, ensures accurate control of drainage, and prevents contact between the inner tub 1 and the water in the gap cavity due to delayed drainage.

[0101] Preferably, step S13 further includes the following steps:

[0102] Step S14: The spray device is controlled to spray the detergent and water mixture onto the laundry to be washed in the inner tub 1. The detergent and water mixture is pre-mixed before entering the spray device.

[0103] The detergent may be a single detergent, such as a laundry detergent, or a detergent mixture having a certain concentration after dilution, and the present invention is not limited thereto.

[0104] Specifically, taking the above-mentioned detergent as an example, when step S13 is adopted, those skilled in the art can adopt the following method. For example, first, spray water on the clothes to be washed until they are fully soaked, and then spray detergent on them to adhere the detergent to the clothes. When step S14 is adopted, those skilled in the art can adopt the following method. For example, first, spray water on the clothes to be washed until they are wet, and then spray a mixture of detergent and water on them until they are fully soaked and the detergent adheres to them. This method first wets the clothes to be washed but does not completely soak them, and allows them to be fully soaked under the action of the mixture of detergent and water, allowing the detergent to adhere better and more uniformly to the clothes to be washed, ensuring subsequent laundry effectiveness while saving the amount of detergent used and the amount of water sprayed.

[0105] Alternatively, in an alternative embodiment, step S1 specifically includes the following steps:

[0106] In step S110, the spray device is controlled to spray detergent onto the laundry to be washed in the inner tub 1.

[0107] In step S120, the inner tank 1 is controlled to rotate back and forth.

[0108] In step S130, the spray device is controlled to spray water onto the laundry to be washed in the inner tub 1.

[0109] In step S1, first, steps S110 and S120 are repeatedly executed a plurality of times, and then steps S120 and S130 are repeatedly executed a plurality of times.

[0110] Alternatively, in an alternative embodiment, step S110 further includes the following steps:

[0111] The spray device is controlled to spray a mixture of detergent and water onto the clothes to be washed in the inner tub 1.

[0112] Alternatively, in an alternative embodiment, step S1 specifically includes alternately performing the following steps:

[0113] In step S1100, the spray device is controlled to spray a mixture of detergent and water onto the clothes to be washed in the inner tub 1.

[0114] In step S1200, the inner tank 1 is controlled to rotate back and forth.

[0115] The control method is used in the wash phase of a drum washing machine.

[0116] Alternatively, in an alternative embodiment, step S1 specifically includes the following steps:

[0117] First, the spray device is controlled to spray water onto the clothes to be washed in the inner tub 1.

[0118] Next, the spray device is controlled to spray detergent onto the clothes to be washed in the inner tub 1.

[0119] After the clothes to be washed in the inner tub are sufficiently wetted, the inner tub is controlled to rotate back and forth.

[0120] Here, the step of "controlling the spray device to spray detergent onto the laundry to be washed in the inner tub 1" further includes the following steps.

[0121] The spray device is controlled to spray a mixture of detergent and water onto the clothes to be washed in the inner tub 1.

[0122] Alternatively, in an alternative embodiment, the control method is used in the washing stage of a drum-type washing machine. Step S1 specifically includes the following steps:

[0123] First, the spray device is controlled to spray detergent onto the clothes to be washed in the inner tub 1.

[0124] Next, the spray device is controlled to spray water onto the clothes to be washed in the inner tub 1.

[0125] After the clothes to be washed in the inner tub 1 are sufficiently wetted, the inner tub 1 is controlled to rotate back and forth.

[0126] Here, the step of "controlling the spray device to spray detergent onto the laundry to be washed in the inner tub 1" further includes the following steps.

[0127] The spray device is controlled to spray a mixture of detergent and water onto the clothes to be washed in the inner tub 1.

[0128] Alternatively, in an alternative embodiment, the control method is used in the washing stage of a drum-type washing machine. Step S1 specifically includes the following steps:

[0129] First, the spray device is controlled to spray a mixture of detergent and water onto the clothes to be washed in the inner tub 1.

[0130] Next, after the laundry to be washed in the inner tub has been sufficiently wetted, the inner tub 1 is controlled to rotate back and forth.

[0131] 4, which is a flowchart showing the specific procedure of step S1 in the rinsing stage of the drum-type washing machine control method of the present invention. As shown in FIG. 4, in the rinsing stage of the drum-type washing machine, the step of "controlling and rotating inner tub 1" specifically includes the following steps:

[0132] In step S15, water is sprayed onto the laundry to be washed in the inner tub 1, and at the same time, the inner tub 1 is controlled to rotate back and forth.

[0133] In an alternative embodiment, in the rinsing stage of a drum-type washing machine, the step of "controlling and rotating the inner tub 1" specifically includes the following steps.

[0134] In step S16, the operation of spraying water onto the laundry to be washed in the inner tub 1 and the operation of controlling the inner tub 1 to rotate back and forth are alternately performed.

[0135] Specifically, during the rinsing stage, after each rinse, the inner tub 1 is rotated at high speed to remove water from the clothes, and then the next rinse is performed. This cycle is repeated multiple times until the set number of rinses is completed or the machine stops when it detects that the clothes have been rinsed.

[0136] The drum-type washing machine of the present invention further includes a drying system, which is configured to supply hot air into the outer tub 2. The control method of the present invention further includes the following steps.

[0137] Simultaneously with or after spraying water and / or detergent onto the laundry to be washed in the inner tub 1, the drying system is controlled to supply hot air into the outer tub 2.

[0138] Alternatively, in an alternative embodiment, the drum-type washing machine of the present invention further includes a heating element provided at the inner bottom of the outer tub 2, and the heating element is configured to heat the wash water at the inner bottom of the outer tub 2 to generate steam. The control method of the present invention further includes the following steps.

[0139] Simultaneously with or after spraying water and / or detergent onto the clothes to be washed in the inner tub 1, the heating element is controlled to heat the wash water in the inner bottom of the outer tub 2 and generate steam.

[0140] Here, in order to prevent the dry-heating phenomenon of the heating element, when the actual water level in the gap cavity is lower than the dry-heating water level, control is performed so that water is replenished into the gap cavity.

[0141] The temperature of the hot air or steam supplied into the outer tub 2 is not limited in the present invention, and can be set by a person skilled in the art based on the optimum activation temperature that can be achieved by the detergent actually used in actual applications.

[0142] In the above steps, supplying hot air or steam to fumigate the clothes activates the enzymes contained in the detergent added to inner tub 1 during the washing stage, allowing them to better integrate with the clothes and promote dirt removal and cleaning. At the same time, it reduces the amount of detergent used and the number of rinses, making it easier to rinse clothes thoroughly during the rinsing stage and improving the level of cleanliness after washing. In addition, because the clothes are in a steam environment, they can be heated more evenly and energy transfer efficiency can be increased compared to clothes soaked in conventional water, and the environment in inner tub 1 and the clothes can be sterilized while washing.

[0143] Furthermore, hot air or steam is supplied simultaneously with or after spraying water and / or detergent onto the clothes to be washed in the inner tub 1, thereby ensuring that the enzymes contained in the detergent are gradually activated and preventing the enzymes from being deactivated due to excessively high temperatures when spraying the detergent, which could affect the cleaning effect.

[0144] Continuing to refer to FIG. 1, in order to ensure the spray effect of the spray device, it is necessary to detect the water pressure condition before the spray device is activated. The control method of the present invention further includes the following steps:

[0145] Step S4: Normal cleaning water supply is performed, and the actual water level change ΔL in the gap cavity is obtained.

[0146] Step S5: If the actual water level change amount ΔL is higher than the preset water level change amount ΔL', control is performed so that the spray device starts normally.

[0147] Specifically, step S4 specifically includes the following steps:

[0148] Step S41: Control the clearance cavity to drain until it is empty and obtain a first water level L1.

[0149] In step S42, water is supplied to the gap cavity for a preset time t1, and a second water level L2 is obtained.

[0150] Step S43: Calculate the actual water level change amount ΔL.

[0151] Here, the calculation formula for the actual water level change ΔL is as follows: (Formula 1) ΔL=(L2-L1) / t1.

[0152] In the above steps, the present invention detects the water pressure condition using the amount of change in water level, thereby achieving higher accuracy.

[0153] Continuing to refer to FIG. 1, before the spray device is activated, the control method of the present invention further includes the following steps:

[0154] In step S6, the weight and / or material of the clothes to be washed in the inner tub 1 is acquired.

[0155] Step S7: Determine the amount of water and / or detergent to spray based on the weight and / or material of the clothes to be washed.

[0156] Here, for example, in step S6, the weight of the clothes to be washed can be obtained by a weight sensor installed in the inner tub 1, and the material of the clothes to be washed can be obtained using AI camera recognition technology, spectral analysis technology, etc., but the present invention is not limited to this.

[0157] In step S7, a person skilled in the art can pre-store a mapping relationship between different materials and weights of clothes and the amount of water and / or detergent sprayed, and then match the corresponding amount of water and / or detergent sprayed based on the actual weight and / or material of the clothes to be washed. For example, the heavier the weight of the clothes to be washed, the larger the amount of water and / or detergent sprayed and the longer the spray time. Even with the same weight, clothes made of different materials have different water absorption capacities. For example, cotton clothes require a larger amount of water and / or detergent sprayed than synthetic clothes, and accordingly, the amount of water and / or detergent sprayed on cotton clothes is longer than the amount of water and / or detergent sprayed on synthetic clothes.

[0158] In the above steps, the amount of water and / or detergent sprayed can be controlled according to the weight and / or material of the clothes to be washed, thereby ensuring the cleaning effect of the clothes and achieving the purpose of water saving.

[0159] In addition, the number of washes and rinses can be controlled according to the weight and / or material of the clothes to be washed. Users can also customize the number of washes and / or rinses according to their actual washing needs.

[0160] After rinsing, the user can choose whether to dry the clothes or not depending on their needs.

[0161] Second technical solution: CN202310173417.7, Figures 5 to 7, second to seventh embodiments.

[0162] Second Example The present invention provides a method for controlling isolated cleaning of a laundry machine, and the laundry machine may be a drum-type washing machine or a pulsator-type washing machine. The control method of the present invention will be described below using a drum-type washing machine as an example.

[0163] First, let us refer to FIGS. 1 and 5. FIGS. 1 and 5 are structural schematic diagrams of a drum-type washing machine of the present invention. As shown in FIGS. 1 and 5, the drum-type washing machine of the present invention includes an inner tub 1, an outer tub 2, and a spray device (not shown). The inner tub 1 is rotatably mounted within the outer tub 2. The inner tub 1 is used to hold clothes to be washed. A clearance cavity 4 is formed between the inner tub 1 and the outer tub 2. A window gasket 3 is provided between the open end of the front structure of the outer tub 2 and the housing of the washing machine. The spray device is preferably attached to the window gasket 3 and configured to spray into the inner tub 1. Specifically, the spray device may be in the form of a nozzle connected to the water supply box and / or detergent dispenser of the drum-type washing machine via piping. The piping may be provided with a pump or other power device to provide spray pressure. Of course, the spray device may be mounted at a location other than the window gasket 3 or in a form other than a nozzle. However, as long as it can spray into the inner tub 1, the present invention does not impose any limitations on the installation location or physical form of the spray device.

[0164] Next, please refer to Fig. 6. Fig. 6 is a flowchart showing the main steps of the method for controlling the isolation cleaning of a laundry facility according to the present invention. As shown in Fig. 6, the control method of the present invention includes the following steps:

[0165] In step S1, the washing stage, the spray device is controlled to spray water and / or detergent onto the clothes to be washed in the inner tub 1, and the inner tub is controlled to rotate.

[0166] In step S2, the rinsing stage, the operation of spraying water onto the laundry to be washed in the inner tub 1 and the operation of controlling the inner tub 1 to rotate are performed alternately.

[0167] Step S3: The entire program is controlled so that the water in the gap cavity 4 does not come into contact with the inner tank 1 at any time.

[0168] In the cleaning stage, step S1 specifically includes the following steps:

[0169] Step S11: The spray device is controlled to spray water onto the clothes to be washed in the inner tub 1.

[0170] Step S12: The inner tank 1 is controlled to rotate back and forth.

[0171] In step S13, the spray device is controlled to spray detergent onto the laundry to be washed in the inner tub 1.

[0172] Preferably, steps S11 and S12 are first repeated multiple times to soak the laundry to be washed, and then steps S12 and S13 are repeated multiple times to apply the detergent to the laundry to be washed.

[0173] Specifically, during one execution of steps S11 and S12, the spray device is first controlled to spray water onto the clothes to be washed in the inner tub 1, and then the inner tub 1 is controlled to rotate back and forth, and this cycle is repeated multiple times until the preset amount of water sprayed and the preset number of sprays are reached. Similarly, during one execution of steps S12 and S13, the spray device is first controlled to spray detergent onto the clothes to be washed in the inner tub 1, and then the inner tub 1 is controlled to rotate back and forth, and this cycle is repeated multiple times until the preset amount of detergent sprayed and the preset number of sprays are reached.

[0174] Of course, during one execution of steps S11 and S12, the spray of water and the rotation of inner tub 1 may be controlled simultaneously, or the inner tub 1 may be controlled to rotate first and then the spray of water may be controlled. Similarly, during one execution of steps S12 and S13, the spray of detergent and the rotation of inner tub 1 may be controlled simultaneously, or the inner tub 1 may be controlled to rotate first and then the spray of detergent may be controlled. These adjustments do not deviate from the principles of the present invention and are therefore within the scope of protection of the present invention.

[0175] Furthermore, the detergent may be a concentrate or a mixture of concentrate and water, but the present invention is not limited thereto. For example, water may be first sprayed onto the clothes to be washed, allowing the clothes to be fully soaked, and then a high-concentration detergent may be sprayed onto the clothes to allow the detergent to adhere to the clothes. Alternatively, water may be first sprayed onto the clothes to wet them, and then a low-concentration detergent may be sprayed onto the clothes to allow the clothes to be fully soaked and allow the detergent to adhere to the clothes. This method wets the clothes to be washed but does not completely soak them, allowing them to be fully soaked under the action of the detergent, which allows the detergent to adhere to the clothes better and more uniformly, ensuring subsequent laundry effects while saving the amount of detergent used and the amount of water sprayed.

[0176] Preferably, step S13 further includes the following steps:

[0177] In step S131, the spray device is controlled to spray a mixture of detergent and water onto the clothes to be washed in the inner tub 1.

[0178] In step S2, a rinsing method is adopted in which spraying and rotation of the inner tub 1 are controlled to alternate, so that the clothes to be washed are dispersed as the inner tub 1 rotates, preventing the clothes from overlapping, and allowing the mixed solution to be sprayed more evenly onto the clothes to be washed. Meanwhile, a dotted water supply method is formed, which ensures the accuracy of the water supply level entering the gap cavity, ensures accurate control of drainage, and prevents contact between the inner tub 1 and the water in the gap cavity due to delayed drainage.

[0179] After each rinse, the inner tub 1 is rotated at high speed to remove water from the clothes, and then the next rinse is performed. This cycle is repeated multiple times until the set number of rinses is completed or the machine stops when it is detected that the clothes have been rinsed.

[0180] Step S3 specifically includes the following steps.

[0181] Step S31: The actual water level height in the gap cavity 4 is acquired in real time throughout the program.

[0182] Step S32: If the actual water level is higher than the preset water level, the gap cavity 4 is controlled to drain water so that the water in the gap cavity 4 does not always contact the inner tank 1.

[0183] In this embodiment, a water level sensor (not shown) is provided in the gap cavity 4 to detect the actual water level in the gap cavity 4. The preset water level is a water level that does not always come into contact with the edge of the inner tank 1.

[0184] Alternatively, in an alternative embodiment, step S3 specifically includes the following steps:

[0185] In step S33, the gap cavity 4 is maintained in a drained state throughout the entire program so that the water in the gap cavity 4 does not come into contact with the inner tank 1. Maintaining the drained state of the gap cavity 4 can be achieved by always leaving the drain port communicating with the gap cavity 4 open and draining the water using the principle of gravity drainage. It can also be achieved by always keeping the drain pump in the drain pipe communicating with the gap cavity 4 on and draining the water using the principle of power drainage.

[0186] Throughout the entire washing cycle, the spray device sprays water and / or detergent directly onto the clothes in the inner tub 1. The sprayed water and / or detergent first enters the inner tub 1 and contacts the clothes, then enters the gap cavity 4, and finally exits the gap cavity 4. This ensures that the water and / or detergent sprayed onto the clothes is always clean. At the same time, the liquid in the gap cavity 4 does not constantly come into contact with the inner tub 1. As the inner tub 1 rotates, the water in the gap cavity 4 does not re-enter the inner tub 1. This prevents bacteria in the gap cavity 4 from being carried into the inner tub 1 and adhering to the clothes, preventing cross-contamination of the clothes. Furthermore, because the water in the gap cavity 4 does not constantly come into contact with the inner tub 1, the inner tub 1 does not need to overcome resistance from contact with water during rotation, thereby reducing power consumption compared to conventional washing machines. Furthermore, using the spray mode to wash clothes allows the liquid to be sprayed more evenly onto the clothes, ensuring effective cleaning and saving water.

[0187] It should be noted that "throughout the entire process" in step S3 refers to the execution of the entire washing process, including the washing step, rinsing step, and spin-drying step.

[0188] Third Example In the cleaning stage, step S1 specifically differs from the second embodiment in that it includes the following steps.

[0189] In step S110, the spray device is controlled to spray detergent onto the laundry to be washed in the inner tub 1.

[0190] In step S120, the inner tank 1 is controlled to rotate back and forth.

[0191] In step S130, the spray device is controlled to spray water onto the laundry to be washed in the inner tub 1.

[0192] Preferably, steps S110 and S120 are first repeated multiple times to apply detergent to the laundry to be washed, and then steps S120 and S130 are repeated multiple times to soak the laundry to be washed.

[0193] Specifically, during one execution of steps S110 and S120, the spray device is first controlled to spray detergent onto the clothes to be washed in the inner tub 1, and then the inner tub 1 is controlled to rotate back and forth, and this cycle is repeated multiple times until the preset amount of detergent sprayed and the preset number of sprays are reached. Similarly, during one execution of steps S120 and S130, the spray device is first controlled to spray water onto the clothes to be washed in the inner tub 1, and then the inner tub 1 is controlled to rotate back and forth, and this cycle is repeated multiple times until the preset amount of water sprayed and the preset number of sprays are reached.

[0194] Of course, during one execution of steps S110 and S120, the control may be such that the spray of detergent and the rotation of inner tub 1 are performed simultaneously, or the inner tub 1 is first controlled to rotate and then the spray of detergent is controlled. Similarly, during one execution of steps S120 and S130, the control may be such that the spray of water and the rotation of inner tub 1 are performed simultaneously, or the inner tub 1 is first controlled to rotate and then the spray of water is controlled. These adjustments do not deviate from the principles of the present invention and are therefore within the scope of protection of the present invention.

[0195] Preferably, step S110 further includes the following steps:

[0196] In step S1101, the spray device is controlled to spray a mixture of detergent and water onto the clothes to be washed in the inner tub 1.

[0197] Fourth Example In the cleaning stage, step S1 specifically differs from the second embodiment in that it includes the following steps.

[0198] In step S1100, the spray device is controlled to spray a mixture of detergent and water onto the clothes to be washed in the inner tub 1.

[0199] In step S1200, the inner tank 1 is controlled to rotate back and forth.

[0200] Steps S1100 and S1200 are alternately executed and repeated multiple times until the preset spray amount and number of sprays are reached.

[0201] In the above step, by adopting a method of alternately controlling the spray and the rotation of the inner tub 1 to perform washing, the clothes to be washed are dispersed as the inner tub 1 rotates, preventing the clothes from overlapping, and allowing the mixed solution to be sprayed more evenly onto the clothes to be washed. Meanwhile, a dotted water supply method is formed to ensure the accuracy of the water supply level entering the gap cavity 4, ensuring accurate control of drainage and preventing contact between the inner tub 1 and the water in the gap cavity 4 due to delayed drainage.

[0202] Fifth Example In the cleaning stage, step S1 specifically differs from the second embodiment in that it includes the following steps.

[0203] First, the spray device is controlled to spray water onto the clothes to be washed in the inner tub 1.

[0204] Next, the spray device is controlled to spray detergent onto the clothes to be washed in the inner tub 1.

[0205] After the clothes to be washed in the inner tub 1 are sufficiently wetted, the inner tub 1 is controlled to rotate back and forth.

[0206] Preferably, the step of "controlling the spray device to spray detergent onto the clothes to be washed in the inner tub 1" further includes the following steps.

[0207] The spray device is controlled to spray a mixture of detergent and water onto the clothes to be washed in the inner tub 1.

[0208] Sixth Example In the cleaning stage, step S1 specifically differs from the second embodiment in that it includes the following steps.

[0209] First, the spray device is controlled to spray detergent onto the clothes to be washed in the inner tub 1.

[0210] Next, the spray device is controlled to spray water onto the clothes to be washed in the inner tub 1.

[0211] After the clothes to be washed in the inner tub 1 are sufficiently wetted, the inner tub 1 is controlled to rotate back and forth.

[0212] Preferably, the step of "controlling the spray device to spray detergent onto the clothes to be washed in the inner tub 1" further includes the following steps.

[0213] The spray device is controlled to spray a mixture of detergent and water onto the clothes to be washed in the inner tub 1.

[0214] Seventh Example In the cleaning stage, step S1 specifically differs from the second embodiment in that it includes the following steps.

[0215] First, the spray device is controlled to spray a mixture of detergent and water onto the clothes to be washed in the inner tub 1.

[0216] After the clothes to be washed in the inner tub 1 are sufficiently wetted, the inner tub 1 is controlled to rotate back and forth.

[0217] In fact, the concentrations of the mixed solutions in Examples 4 and 7 are much lower than those in Examples 2, 3, 5, and 6. This is because, in Examples 4 and 7, water is no longer sprayed alone, but the water required for cleaning is thoroughly mixed with the detergent. The specific concentration can be flexibly set by those skilled in the art according to their needs, as long as it can ensure the degree of cleaning and subsequent rinsing cleanliness, and the present invention does not impose any limitations thereon.

[0218] In the fifth, sixth and seventh embodiments, the spray-first, then spin washing mode is adopted, so that the clothes to be washed can be loosened after they have fully absorbed the water and / or detergent, ensuring a good washing effect. In actual operation, the spray-first, then spin washing mode is applied when there are only a few clothes to be washed, to avoid uneven spraying on the clothes to be washed due to too many clothes to affect the washing effect.

[0219] Next, please refer to Fig. 7. Fig. 7 is a flowchart of a possible complete procedure of the method for controlling isolated cleaning of a washing facility of the present invention. As shown in Fig. 7, a possible complete flow of the method for controlling isolated cleaning of a washing facility of the present invention is S11-S12-S13-S2-S3.

[0220] Third technical solution: CN202310048381.X, Figures 8-9, eighth embodiment.

[0221] The present invention provides a method for controlling isolated washing of washing equipment, and in the present invention, the washing equipment may be a drum-type washing machine or a pulsator-type washing machine. The control method of the present invention will be described below using a drum-type washing machine as an example. The structure of the drum-type washing machine can be understood in combination with the structure described in the second embodiment.

[0222] Please refer to Figure 8. Figure 8 is a flowchart of the main steps of the isolated cleaning control method for the washing equipment of the present invention, and this control method is used for the entire cleaning process of the washing equipment, which includes all operation processes of washing, rinsing, and spin-drying. As shown in Figure 8, the control method of the present invention includes the following steps:

[0223] Step S1: The spray device is controlled to spray water and / or detergent onto the clothes to be washed in the inner tub 1, and the inner tub 1 is controlled to rotate.

[0224] Step S2: Hot air is supplied into the outer tub 2 simultaneously with, before, or after spraying water and / or detergent onto the laundry to be washed in the inner tub 1.

[0225] Step S3: Control is performed so that the water in the gap cavity 4 does not come into contact with the inner tank 1 throughout the entire cleaning program.

[0226] In this embodiment of the present invention, the spray device sprays water and / or detergent directly onto the clothes in inner tub 1 throughout the entire wash cycle. The sprayed water and / or detergent first enters inner tub 1 and contacts the clothes, then enters gap cavity 4, and finally exits gap cavity 4. This ensures that the water and / or detergent sprayed onto the clothes is always clean and not reused. At the same time, the water in gap cavity 4 does not constantly come into contact with the inner tub. As inner tub 1 rotates, the water in gap cavity 4 does not re-enter the inner tub. This prevents bacteria in gap cavity 4 from being carried into inner tub 1 and adhering to the clothes, preventing cross-contamination of the clothes. Furthermore, because the water in gap cavity 4 does not constantly come into contact with inner tub 1, the rotation of inner tub 1 does not need to overcome resistance due to contact with water. This reduces power consumption compared to conventional drum-type washing machines. Furthermore, using the spray mode to wash clothes allows water and / or detergent to be sprayed more evenly onto the clothes, ensuring effective cleaning and saving water.

[0227] In the cleaning stage, step S1 specifically includes the following steps:

[0228] The clothes to be washed in the inner tub 1 are washed with running water by alternately controlling the spray device to spray water and / or detergent onto the clothes to be washed in the inner tub 1 and controlling the inner tub 1 to rotate it. That is, first, the process of controlling the spray device to spray water onto the clothes to be washed in the inner tub 1 and controlling the inner tub 1 to rotate it back and forth is repeated multiple times, and then the process of controlling the spray device to spray detergent onto the clothes to be washed in the inner tub 1 and controlling the inner tub 1 to rotate it back and forth is repeated multiple times.

[0229] Although the above description relates to the alternating operation of the inner tub 1 and the spray device, this is not limiting, and those skilled in the art can, according to their needs, control the inner tub 1 to rotate back and forth while the spray device sprays water and / or detergent, or control the inner tub 1 to rotate back and forth after the clothes to be washed are sufficiently wetted first. These adjustments do not deviate from the principles of the present invention and are therefore also included within the scope of protection of the present invention.

[0230] Here, the step of controlling the spray device to spray water and / or detergent onto the clothes to be washed in the inner tub 1 specifically includes the steps of first controlling the spray device to spray water onto the clothes to be washed in the inner tub 1 to wet the clothes to be washed, and then controlling the spray device to spray detergent onto the clothes to be washed in the inner tub 1 to adhere the detergent to the clothes to be washed.

[0231] The detergent may be a single detergent, such as a laundry detergent, or a detergent mixture having a certain concentration after dilution, and the present invention is not limited thereto.

[0232] In the rinsing stage, step S1 specifically includes the following steps.

[0233] In step S11, water is sprayed onto the laundry to be washed in the inner tub 1, and at the same time, the inner tub 1 is controlled to rotate back and forth.

[0234] Alternatively, in an alternative embodiment, in the rinsing stage, step S1 specifically includes the following steps:

[0235] In step S12, the operation of spraying water onto the laundry to be washed in the inner tub 1 and the operation of controlling the inner tub 1 to rotate back and forth are alternately performed.

[0236] In an embodiment of the present invention, during the rinsing stage, after each rinse, the inner tub 1 is rotated at high speed to remove water from the clothes, and then the next rinse is performed. This cycle is repeated multiple times until the set number of rinses is completed or the machine stops when it is detected that the clothes have been rinsed.

[0237] The washing equipment further includes a drying system, which is a heat pump drying system and / or an electric heating drying system. Here, the heat pump drying system includes a fan, a compressor, an evaporator, and a condenser, and air is heated as it passes through the condenser and sent to the inner tub. Adding an electric heating drying system to the heat pump drying system can improve the temperature rise rate. The step of "supplying hot air into the outer tub 2" in step S2 specifically includes the following steps.

[0238] Step S21: Control the drying system to supply hot air into the outer tub.

[0239] In an embodiment of the present invention, by supplying hot air to fumigate the clothes, the enzymes contained in the detergent added to the inner tub 1 are activated during the washing stage, allowing them to better integrate with the clothes and promote dirt removal and cleaning, while also reducing the amount of detergent used and the number of rinses, making it easier to rinse the clothes thoroughly during the rinsing stage and improving the level of cleanliness after washing.In addition, because the clothes are in a steam environment, they can be heated more evenly and energy transfer efficiency can be increased compared to conventional clothes soaked in water, and the environment of the inner tub 1 and the clothes can be sterilized while washing.

[0240] Furthermore, to ensure the heat transfer efficiency of hot air, improve energy utilization, quickly raise the temperature of clothes during the washing process, and reduce frequent operation of the drying system, which can shorten the life of parts, in this embodiment of the present invention, the drying system is first controlled to start, quickly heat up to a set temperature range, and then stopped. The selection of this temperature range depends on the weight and material of the clothes to be washed; the heavier the weight of the clothes to be washed and the more water-absorbent the material of the clothes to be washed, the higher the set upper temperature limit. Next, the clothes are heated using residual heat in the tub, and the temperature change in the tub is monitored in real time. If the actual temperature is lower than the set temperature, the drying system is controlled to start again, and if the actual temperature reaches or exceeds the set temperature, the drying system is controlled to stop operation. Furthermore, in the case of a combined washing and drying washing machine, if a user requests drying, the clothes can be first heated after the spin cycle is completed and then the drying program is started, thereby raising the surface temperature of the clothes and improving drying efficiency.

[0241] Furthermore, since condensed water may be present during drying, it is necessary to prevent the water in the clearance cavity 4 from contacting the inner tank at any time.

[0242] Step S3 specifically includes the following steps.

[0243] Step S31: Obtain the actual water level height in the gap cavity 4 in real time throughout the entire cleaning program.

[0244] Step S32: If the actual water level is higher than the preset water level, the gap cavity 4 is controlled to drain water so that the water in the gap cavity 4 does not always contact the inner tank 1.

[0245] In the embodiment of the present invention, a water level sensor (not shown) is provided in the gap cavity 4 to detect the actual water level in the gap cavity 4. The preset water level is a water level that does not always come into contact with the edge of the inner tank 1.

[0246] Alternatively, in an alternative embodiment, step S3 specifically includes the following steps:

[0247] Step S33: The gap cavity 4 is maintained in a drained state so that the water in the gap cavity 4 does not always come into contact with the inner tank 1 throughout the entire cleaning program.

[0248] In the embodiment of the present invention, maintaining the drainage state of the clearance cavity 4 can be achieved by always keeping the drain port communicating with the clearance cavity 4 open and draining using the principle of gravity drainage. It can also be achieved by always keeping the drain pump of the drain pipe communicating with the clearance cavity 4 on and draining using the principle of power drainage.

[0249] In order to ensure the spray effect of the spray device, it is necessary to detect the water pressure condition. Before step S1, the control method of the present invention further includes the following steps:

[0250] Step S4: Before the spray device is started, normal cleaning water supply is performed and the actual water level change ΔL in the gap cavity 4 is obtained.

[0251] Step S5: If the actual water level change amount ΔL is higher than the preset water level change amount ΔL′, the spray device is started normally.

[0252] Specifically, step S4 includes the following steps.

[0253] Step S41: Drain the clearance cavity 4 to empty it and obtain a first water level L1.

[0254] Step S42: Water is supplied to the gap cavity 4 for a preset time t1 to obtain a second water level L2.

[0255] Step S43: Calculate the actual water level change amount ΔL.

[0256] Here, the calculation formula for the actual water level change ΔL is as follows: (Formula 2) ΔL=(L2-L1) / t1.

[0257] In the embodiment of the present invention, the accuracy is improved by detecting the water pressure condition using the amount of change in water level.

[0258] Before step S1, the control method of the present invention further includes the following steps.

[0259] Step S6: Before the spray device is started, the weight and / or material of the clothes to be washed in the inner tub 1 is obtained.

[0260] Step S7: Control the amount of water and / or detergent sprayed depending on the weight and / or material of the clothes to be washed.

[0261] Here, for example, in step S6, the weight of the clothes to be washed can be obtained by a weight sensor installed in the inner tub 1, and the material of the clothes to be washed can be obtained using AI camera recognition technology, spectral analysis technology, etc., but the present invention is not limited to this.

[0262] In step S7, a person skilled in the art can pre-store a mapping relationship between different materials and weights of clothes and the amount of water and / or detergent sprayed, and then match the corresponding amount of water and / or detergent sprayed based on the actual weight and / or material of the clothes to be washed. For example, the heavier the weight of the clothes to be washed, the larger the amount of water and / or detergent sprayed and the longer the spray time. Even with the same weight, clothes made of different materials have different water absorption capacities. For example, cotton clothes require a larger amount of water and / or detergent sprayed than synthetic clothes, and accordingly, the amount of water and / or detergent sprayed on cotton clothes is longer than the amount of water and / or detergent sprayed on synthetic clothes.

[0263] In an embodiment of the present invention, the amount of water and / or detergent sprayed can be controlled according to the weight and / or material of the clothes to be washed, thereby ensuring the cleaning effect of the clothes while also achieving the purpose of water saving.

[0264] In addition, the number of washes and rinses can be controlled according to the weight and / or material of the clothes being washed. Users can also customize the number of washes and / or rinses according to their actual washing needs.

[0265] After rinsing, the user can choose whether to dry the clothes or not depending on their needs.

[0266] Next, please refer to Fig. 9. Fig. 9 is a flowchart of a possible complete procedure of the isolated cleaning control method for a washing equipment of the present invention. As shown in Fig. 9, a possible complete flow of the isolated cleaning control method for a washing equipment of the present invention is S4-S5-S6-S7-S1-S2-S31-S32. Here, steps S1-S2-S31-S32 are involved in all operation processes of the washing equipment, including washing, rinsing, and spin-drying.

[0267] Based on the above method embodiment, the present invention further provides a washing installation including a controller, the controller being configured to execute the above isolation washing control method.

[0268] Fourth technical solution: CN202310338633.2, Figures 10 to 12, ninth embodiment.

[0269] The present invention provides a method for controlling isolated washing of washing equipment, and in the present invention, the washing equipment may be a drum-type washing machine or a pulsator-type washing machine. The control method of the present invention will be described below using a drum-type washing machine as an example. The structure of the drum-type washing machine can be understood in combination with the structure described in the second embodiment.

[0270] Next, reference is made to Fig. 11. Fig. 11 is a flowchart showing the main steps of the isolation cleaning control method for the cleaning equipment of the present invention. As shown in Fig. 11, the control method of the present invention includes the following steps.

[0271] Step S1: The spray device is controlled to spray water and / or detergent onto the clothes to be washed in the inner tub 1, and the inner tub 1 is controlled to rotate.

[0272] Step S2: When the spray device stops spraying water and / or detergent onto the clothes to be washed in the inner tub and the clearance cavity stops draining, water vapor is supplied into the outer tub.

[0273] Step S3: The entire program is controlled so that the water in the gap cavity 4 does not come into contact with the inner tank 1 at any time.

[0274] It should be noted that "throughout the entire process" in step S3 refers to the execution of the entire washing process, including the washing step, rinsing step, and spin-drying step.

[0275] In this embodiment of the present invention, the spray device sprays water and / or detergent directly onto the clothes in inner tub 1 throughout the entire wash cycle. The sprayed water and / or detergent first enters inner tub 1 and contacts the clothes, then enters gap cavity 4, and finally exits gap cavity 4. This ensures that the water and / or detergent sprayed onto the clothes is always clean and not reused. Furthermore, the water in gap cavity 4 does not constantly come into contact with inner tub 1. As inner tub 1 rotates, the water in gap cavity 4 does not re-enter the inner tub 1. This prevents bacteria in gap cavity 4 from being carried into the inner tub 1 and adhering to the clothes, preventing cross-contamination of the clothes. Furthermore, because the water in gap cavity 4 does not constantly come into contact with inner tub 1, the rotation of inner tub 1 does not require overcoming resistance due to contact with water. This reduces power consumption compared to conventional drum-type washing machines. Furthermore, using the spray mode to wash clothes allows water and / or detergent to be sprayed more evenly onto the clothes, ensuring effective cleaning and saving water.

[0276] In the cleaning stage, step S1 specifically includes the following steps:

[0277] The clothes to be washed in the inner tub 1 are washed with running water by alternately controlling the spray device to spray water and / or detergent onto the clothes to be washed in the inner tub 1 and controlling the inner tub 1 to rotate it. That is, first, the process of controlling the spray device to spray water onto the clothes to be washed in the inner tub 1 and controlling the inner tub 1 to rotate it back and forth is repeated multiple times, and then the process of controlling the spray device to spray detergent onto the clothes to be washed in the inner tub 1 and controlling the inner tub 1 to rotate it back and forth is repeated multiple times.

[0278] Although the above description relates to the alternating operation of the inner tub 1 and the spray device, this is not limiting, and those skilled in the art can, according to their needs, control the inner tub 1 to rotate back and forth while the spray device sprays water and / or detergent, or control the inner tub 1 to rotate back and forth after the clothes to be washed are sufficiently wetted first. These adjustments do not deviate from the principles of the present invention and are therefore also included within the scope of protection of the present invention.

[0279] Here, the step of controlling the spray device to spray water and / or detergent onto the clothes to be washed in the inner tub 1 specifically includes the following steps: First, the spray device is controlled to spray water onto the clothes to be washed in the inner tub 1 to wet the clothes to be washed, and then the spray device is controlled to spray detergent onto the clothes to be washed in the inner tub 1 to adhere the detergent to the clothes to be washed.

[0280] The detergent may be a single detergent, such as a laundry detergent, or a detergent mixture having a certain concentration after dilution, and the present invention is not limited thereto.

[0281] In the rinsing stage, step S1 specifically includes the following steps.

[0282] In step S11, water is sprayed onto the laundry to be washed in the inner tub 1, and at the same time, the inner tub 1 is controlled to rotate back and forth.

[0283] Alternatively, in an alternative embodiment, in the rinsing stage, step S1 specifically includes the following steps:

[0284] In step S12, the operation of spraying water onto the laundry to be washed in the inner tub 1 and the operation of controlling the inner tub 1 to rotate back and forth are alternately performed.

[0285] In an embodiment of the present invention, during the rinsing stage, after each rinse, the inner tub 1 is rotated at high speed to remove water from the clothes, and then the next rinse is performed. This cycle is repeated multiple times until the set number of rinses is completed or the machine stops when it is detected that the clothes have been rinsed.

[0286] As shown in Figure 10, the cleaning equipment further includes a heating element 5 provided at the inner bottom of the outer tank 2, and a groove 21 is provided at the inner bottom of the outer tank 2, and the heating element 5 is an electric heating tube provided in the groove 21. The step of "supplying steam into the outer tank 2" in step S2 is specifically a step of controlling the heating element 5 to heat the cleaning water at the inner bottom of the outer tank 2 and generate steam.

[0287] In an embodiment of the present invention, by supplying steam to fumigate the clothes, the enzymes contained in the detergent added to the inner tub 1 are activated during the washing stage, allowing them to better integrate with the clothes and promote dirt removal and cleaning, while also reducing the amount of detergent used and the number of rinses, making it easier to rinse the clothes thoroughly during the rinsing stage and improving the level of cleanliness after washing.In addition, because the clothes are in a steam environment, they can be heated more evenly and energy transfer efficiency can be increased compared to clothes soaked in conventional water, and the environment of the inner tub 1 and the clothes can be sterilized while washing.

[0288] Furthermore, step S2 specifically includes the following steps.

[0289] S21: After controlling the spray device to stop spraying water and / or detergent onto the laundry to be washed in the inner tub 1, first rotate the inner tub 1.

[0290] S22: The gap cavity 4 is in a state where drainage is stopped, and water vapor is supplied into the outer tank 2.

[0291] Alternatively, an alternative embodiment of step S22 specifically includes the following steps:

[0292] S23: When the clearance cavity 4 is in a draining state and the clearance cavity 4 stops draining water, or at the same time, after the clearance cavity 4 stops draining water, water vapor is supplied into the outer tank 2.

[0293] In the above steps, the heating element 5 does not operate when the washing equipment is at least supplying water or draining water. This means that steam is not supplied to the outer tub 2 at this time. This is because the washing water level in the clearance cavity 4 is unstable when the washing equipment is supplying water or draining water. If heating were to be performed at this time, the newly heated washing water would be discharged when draining water, or the heating temperature during water supply would be insufficient to generate steam, resulting in energy waste and preventing maximum energy utilization. Therefore, to improve energy utilization, the washing equipment of the present invention only operates the heating element 5, i.e., supplies steam to the outer tub 2, when the water supply and drainage are stopped.

[0294] When steam is supplied into the outer tub 2, water droplets still fall into the gap cavity 4 while the wet clothes are being hammer-washed, causing the water level in the gap cavity 4 to rise. To prevent the water in the gap cavity 4 from coming into contact with the inner tub, it is necessary to drain the water to maintain a stable water level. This causes the water level in the gap cavity 4 to become unstable. Therefore, in a preferred embodiment, to supply steam while maintaining a stable water level in the gap cavity 4, after the water supply to the washing equipment is completed, the clothes are hammer-washed for a certain period of time, and steam is supplied until the water level stabilizes. Specifically, in step S22, if there is no change in the water level in the gap cavity 4 after the inner tub 1 has rotated for a certain period of time and hammer-washed the clothes to be washed, or if there is a change in the water level but there is no need to control the gap cavity 4 to drain the water, steam is directly supplied. In step S23, after the inner tub 1 has rotated for a certain period of time to impact wash the clothes to be washed, if a change occurs in the water level in the gap cavity 4 and drainage is required, steam is supplied simultaneously with or after drainage is completed.

[0295] Furthermore, to ensure efficient heat transfer of steam during the supply of water vapor, rapidly increase the temperature of clothes during the washing process, and reduce frequent heating of the heating element 5, which can shorten the lifespan of the components, in this embodiment of the present invention, the heating element 5 is first controlled and activated, rapidly heats the clothes to a temperature range where the water vapor can rapidly evaporate, and then stops heating. Here, the rapid evaporation temperature range is, for example, 70°C to 90°C. The selection of this temperature range depends on the weight of the clothes to be washed; the heavier the clothes to be washed, the higher the set upper limit of the rapid evaporation temperature. Next, the residual heat in the tub is used to heat the clothes, and the temperature change in the tub is monitored in real time. If the actual temperature is lower than the set temperature, the heating element 5 is controlled to operate again. If the actual temperature reaches or exceeds the set temperature, the heating element 5 is controlled to stop heating. Furthermore, in the case of a combined washer-dryer washing machine, if a user requests drying, the clothes can be first steam-heated after the spin cycle is completed and then the drying program is started, thereby increasing the surface temperature of the clothes and improving drying efficiency.

[0296] Step S3 specifically includes the following steps.

[0297] Step S31: Obtain the actual water level height in the gap cavity 4 in real time throughout the entire cleaning program.

[0298] Step S32: If the actual water level is higher than the preset water level, the gap cavity 4 is controlled to drain water so that the water in the gap cavity 4 does not always contact the inner tank 1.

[0299] In the embodiment of the present invention, a water level sensor (not shown) is provided in the gap cavity 4 to detect the actual water level in the gap cavity 4. The preset water level is a water level that does not always come into contact with the edge of the inner tank 1.

[0300] Preferably, in step S32, the step of "controlling and draining the clearance cavity 4" further includes the following steps:

[0301] Step S321: Control the gap cavity 4 to perform intermittent drainage.

[0302] Here, step 321 specifically includes alternately executing the following steps:

[0303] Step 3211: Controlling the drainage of the clearance cavity 4 for a first preset time.

[0304] Step 3212: Controlling the drainage of the clearance cavity 4 to stop for a second preset time.

[0305] In the above step, if the water level in the clearance cavity 4 rises, the water is intermittently drained from the clearance cavity 4 to form a pulsed drainage method, preventing the cleaning water in the clearance cavity 4 from being emptied and preventing the occurrence of siphoning. Illustratively, the first preset time is 1.5 seconds, and the second preset time is 3 seconds.

[0306] In the embodiment of the present invention, the drainage pump of the drainage pipe communicating with the clearance cavity 4 is intermittently operated to drain the water by utilizing the principle of power drainage.

[0307] In an embodiment of the present invention, the amount of water and / or detergent sprayed can be controlled according to the weight and / or material of the clothes to be washed, thereby ensuring the cleaning effect of the clothes while also achieving the purpose of saving water.

[0308] In addition, the number of washes and rinses can also be controlled according to the weight and / or material of the clothes being washed. Users can also customize the number of washes and / or rinses according to their actual washing needs.

[0309] After rinsing, the user can choose whether to dry the clothes or not depending on their needs.

[0310] Next, reference is made to Fig. 12. Fig. 12 is a flowchart of a possible complete procedure of the method for controlling isolated cleaning of a washing facility of the present invention. As shown in Fig. 12, a possible complete flow of the method for controlling isolated cleaning of a washing facility of the present invention is as follows.
