Background Art

[0003] A washing machine is a common household clothing cleaning equipment. Washing machines are mainly classified into pulsator washing machines and drum washing machines according to the cleaning mode. In the cleaning mode of a conventional drum washing machine, generally, first, water is supplied between the inner tub and the outer tub so that the water level is higher than the inner tub to immerse the clothes in water, and then the inner tub is rotated to "strike" the clothes for cleaning. When the washing machine is used for a long time, bacteria will inevitably multiply between the inner tub and the outer tub. When the user uses the washing machine again to wash clothes, the clothes may be secondarily contaminated, which is not good for health.

[0004] Therefore, in the art, new technical solutions for solving the above problems are required.

Summary of the Invention

Problems to be Solved by the Invention

[0005] Technical proposal #1: CN202211543213.X

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

[0007] The present invention provides a method for controlling isolated washing of a drum-type washing machine, the drum-type washing machine comprising an inner tub, an outer tub, and a spray device, the inner tub being rotatably mounted within the outer tub, the inner tub being used to accommodate clothes to be washed, a gap cavity being formed between the inner tub and the outer tub, the spray device being mounted to spray into the inner tub, and the control method comprising: S1, controlling the spray device to spray water and / or detergent onto the clothes to be washed in the inner tub, and alternating between 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, obtaining the actual water level in the gap cavity; and S3, if the actual water level is higher than a preset water level, controlling the gap cavity to drain the water so that the water in the gap cavity does not always come into contact with the inner tub.

[0008] When the above technical solution is adopted, during the washing and rinsing stages, the spray device sprays directly onto the clothes to be washed in the inner tub. This ensures that the sprayed water and / or detergent first enter the inner tub and come into contact with the clothes, then enter the crevice cavity, and finally is discharged from the crevice cavity. As a result, the water and / or detergent sprayed onto the clothes are always clean and not reused. At the same time, the water in the crevice cavity never comes into contact with the inner tub, and as the inner tub rotates, the water in the crevice cavity does not re-enter the inner tub with the rotation. This prevents bacteria in the crevice cavity from being brought into the inner tub and adhering to the clothes, thus preventing secondary contamination of the clothes. Furthermore, because the water in the crevice cavity never comes into contact with the inner tub, there is no need to overcome the resistance caused by contact with water when the inner tub rotates, and therefore power consumption is reduced compared to conventional drum-type washing machines.

[0009] Furthermore, by employing a spray mode for washing and rinsing clothes, water and / or detergent can be sprayed more evenly onto the clothes, ensuring effective washing and rinsing while also saving water.

[0010] In a specific embodiment of the above-described isolated washing control method for a drum-type washing machine, step S1 specifically includes S11, controlling the spray device to spray water onto the clothes to be washed in the inner tub; S12, controlling the inner tub to rotate back and forth; and S13, controlling the spray device to spray detergent onto the clothes to be washed in the inner tub.

[0012] By adopting the above technical solution, the spray and inner tub rotation are controlled to alternate, allowing the clothes to be washed to be dispersed during the inner tub's rotation, preventing overlapping of clothes and ensuring a more uniform spray of water and / or detergent onto the clothes. At the same time, a point-and-shoot water supply system is formed, guaranteeing the accuracy of the water level entering the gap cavity, ensuring precise control of drainage, and preventing contact between the water in the inner tub and the gap cavity due to delayed drainage.

[0085] Technical proposal 1: CN202211543213.X, Figures 1-4, First embodiment.

[0086] First embodiment First, referring to Figure 1, which is a schematic diagram of the structure of the drum-type washing machine of the present invention. As shown in Figure 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 mounted inside the outer tub 2, and the inner tub 1 is used to hold the clothes to be washed. A gap cavity (not shown in Figure 1) is formed between the inner tub 1 and the outer tub 2. A window packing 3 is provided 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 is mounted so as to be able to spray inside the inner tub 1.

[0087] Next, referring to Figure 2, which is a flowchart of the main steps of the isolation washing control method for a drum-type washing machine of the present invention, the control method is used in the washing and rinsing stages of a drum-type washing machine. As shown in Figure 3, the control method of 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, thereby washing the clothes to be washed in the inner tub 1 with running water.

[0089] Step S2: When the spray device is activated, the actual water level in the crevice 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 the water so that the water in the gap cavity does not always come into contact with the inner tank 1.

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

[0092] During the washing and rinsing stages, the spray device sprays directly onto the clothes to be washed in the inner tub 1. This ensures that the sprayed water and / or detergent first enter the inner tub 1, come into contact with the clothes, then enter the gap cavity, and finally be discharged from 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 never comes into contact with the inner tub 1. As the inner tub 1 rotates, the water in the gap cavity does not re-enter the inner tub 1 with the rotation, preventing bacteria in the gap cavity from entering the inner tub 1 and adhering to the clothes, thus preventing secondary contamination of the clothes. Furthermore, because the water in the gap cavity never comes into contact with the inner tub 1, the inner tub 1 does not need to overcome resistance from contact with water during rotation, and therefore power consumption is reduced compared to conventional drum-type washing machines.

[0093] Furthermore, by employing a spray mode to wash and rinse clothes, water and / or detergent can be sprayed more evenly onto the clothes, ensuring effective washing and rinsing while also providing water-saving benefits.

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

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

[0096] Step S12: Control the inner tank 1 to make it reciprocate and rotate.

[0097] Step S13: The spray device is controlled to spray detergent onto the clothes to be washed in the inner tub 1.

[0098] In the washing stage, first, steps S11 and S12 are repeated multiple times to immerse the garment to be washed, and then steps S12 and S13 are repeated multiple times to allow the detergent to adhere to the garment.

[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. This cycle is repeated multiple times until a preset amount and number of sprays of water 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. This cycle is repeated multiple times until a preset amount and number of sprays of detergent are reached.

[0100] In the above steps, by controlling the spraying and rotation of the inner tub 1 to occur alternately, 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 sprayed onto the clothes to be washed to be sprayed more uniformly. At the same time, a point-and-shoot water supply system is formed, ensuring the accuracy of the water level entering the gap cavity, thus ensuring precise control of drainage and preventing contact between the water in the inner tub 1 and the water in the gap cavity due to delays in 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 clothes to be washed in the inner tub 1. The detergent and water mixture is pre-mixed before entering the spray device.

[0103] The above-mentioned detergent may be a single detergent, such as a laundry detergent, or a detergent mixture having a certain concentration after dilution; the present invention is not limited to these.

[0104] Specifically, taking the above-mentioned detergent as a single detergent as an example, if step S13 is adopted, a person skilled in the art can adopt the following method. For example, first spray water onto the garment to be washed to fully immerse it, and then spray detergent onto the garment to allow the detergent to adhere to it. If step S14 is adopted, a person skilled in the art can adopt the following method. For example, first spray water onto the garment to be washed to wet it, and then spray a mixed solution of detergent and water onto the garment to fully immerse it and allow the detergent to adhere to it. This method first wets the garment to be washed, but does not completely immerse it. By thoroughly immersing it under the action of the detergent and water mixture, the detergent adheres to the garment more effectively and uniformly, ensuring the subsequent garment washing effect, while also saving on the amount of detergent and spray water used.

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

[0106] Step S110: The spray device is controlled to spray detergent onto the clothes to be washed in the inner tub 1.

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

[0108] Step S130: The spray device is controlled to spray water onto the clothes to be washed in the inner tub 1.

[0109] In step S1, steps S110 and S120 are executed multiple times, and then steps S120 and S130 are executed multiple times.

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

[0111] The spray device is controlled to spray a mixed solution 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 the step of performing the following steps alternately:

[0113] Step S1100: The spray device is controlled to spray a mixed solution 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 during the washing phase of a drum-type 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 inside the inner tub are sufficiently wet, the inner tub is controlled to rotate back and forth.

[0120] Here, 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:

[0121] The spray device is controlled to spray a mixed solution 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 inside the inner tub 1 are sufficiently wet, 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 clothes to be washed in the inner tub 1" further includes the following steps:

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

[0130] Next, after the clothes to be washed inside the inner tub are sufficiently wet, the inner tub 1 is controlled to rotate back and forth.

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

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

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

[0134] In step S16, the process alternates between spraying water onto the clothes to be washed inside the inner tub 1 and controlling the inner tub 1 to rotate back and forth.

[0135] Specifically, during the rinsing stage, after each rinse is completed, the inner tub 1 is rotated at high speed to remove water adhering to 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 after detecting that the clothes have finished rinsing.

[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 clothes 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, the heating element being 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, a heating element is controlled to heat the washing water at the bottom of the outer tub 2, thereby generating steam.

[0140] To prevent the heating element from overheating, the system controls the supply of water to the crevice cavity if the actual water level in the crevice cavity is lower than the water level at which overheating would occur.

[0141] The temperature of the hot air or steam supplied into the outer tank 2 is not limited in this invention, and those skilled in the art can set it based on the optimal activation temperature that the detergent actually used can achieve in an actual application.

[0142] In the above steps, by supplying hot air or steam to fumigate the clothes, the enzymes contained in the detergent introduced into the inner tub 1 are activated during the washing stage, allowing them to better blend with the clothes and promote dirt removal and cleaning. At the same time, the amount of detergent used and the number of rinses can be reduced, making it easier to rinse the clothes thoroughly during the rinsing stage and improving the degree of cleanliness. In addition, because the clothes are in a steam environment, the clothes can be heated more uniformly compared to clothes immersed in water in the conventional method, increasing energy transfer efficiency, and the environment of the inner tub 1 and the clothes can be sterilized and disinfected while washing.

[0143] Furthermore, by supplying hot air or steam simultaneously with or after spraying water and / or detergent onto the clothes to be washed in the inner tub 1, it is possible to ensure that the enzymes contained in the detergent are gradually activated, preventing the enzymes from becoming inactive due to excessively high temperatures when spraying the detergent, which could affect the cleaning effect.

[0144] As shown in Figure 1, in order to ensure the spraying effect of the spray device, it is necessary to detect the water pressure conditions, and before the spray device is activated, the control method of the present invention further includes the following steps.

[0145] Step S4: Perform a normal flushing water supply and obtain the actual water level change ΔL in the crevice cavity.

[0146] In step S5, if the actual water level change ΔL is higher than the preset water level change ΔL', the spray device is controlled to start up normally.

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

[0148] Step S41, control the gap cavity and drain it until it is empty, obtaining the first water level L1.

[0149] In step S42, the system controls the supply of water to the gap cavity for a predetermined time t1, and obtains a second water level L2.

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

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

[0152] In the steps described above, the present invention achieves higher accuracy by detecting the water pressure situation using the amount of water level change.

[0153] As shown in Figure 1, before the spray device is activated, the control method of the present invention further includes the following steps.

[0154] Step S6, obtain the weight and / or material of the clothes to be washed in the inner tub 1.

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

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

[0157] In step S7, a person skilled in the art would pre-store a mapping relationship between different garment materials and weights and the amount of water and / or detergent sprayed, and then match the corresponding amount of water and / or detergent sprayed based on the weight and / or material of the garment to be cleaned. For example, the heavier the garment to be cleaned, the greater the amount of water and / or detergent sprayed and the longer the spraying time. Even at the same weight, garments of different materials will have different water absorption rates. For example, the amount of water and / or detergent sprayed required for cotton garments is greater than that required for synthetic fiber garments, and accordingly, the spraying time required for cotton garments is longer than that required for synthetic fiber garments.

[0158] In the steps described above, by controlling the amount of water and / or detergent sprayed according to the weight and / or material of the clothing to be washed, it is possible to ensure the cleaning effect of the clothing while also achieving the objective of water conservation.

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

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

[0161] Second technical proposal: CN202310173417.7, Figures 5-7, Second to Seventh Embodiments.

[0162] Second example This invention provides a method for controlling isolated washing in a washing machine. In this invention, the washing machine may be a drum-type washing machine or a pulsator-type washing machine. The control method of this invention will be described below using a drum-type washing machine as an example.

[0163] First, refer to Figures 1 and 5. Figures 1 and 5 are schematic diagrams of the structure of the drum-type washing machine of the present invention. As shown in Figures 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 and is used to hold the clothes to be washed. A gap cavity 4 is formed between the inner tub 1 and the outer tub 2. A window packing 3 is provided between the opening 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 packing 3 and is configured to spray into the inner tub 1. Specifically, the spray device can be provided in the form of a nozzle, which is connected via piping to the water supply box and / or detergent dispenser of the drum-type washing machine, and the piping may be provided with a pump or other power device to provide spray pressure. Of course, the spray device may be mounted in a location other than the window packing 3 and may be provided in a form other than a nozzle, as long as it can spray into the inner tub 1, and the present invention does not limit the installation location and physical form of the spray device in any way.

[0164] Next, refer to Figure 6. Figure 6 is a flowchart of the main steps of the isolation washing control method for the washing equipment of the present invention. As shown in Figure 6, the control method of the present invention includes the following steps.

[0165] In step S1, during the washing phase, 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 clothes to be washed in the inner tub 1 and the operation of controlling and rotating the inner tub 1 are performed alternately.

[0167] Step S3: The program controls the water in the gap cavity 4 so that it does not always come into contact with the inner tank 1.

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

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

[0170] Step S12: Control the inner tank 1 to make it reciprocate and rotate.

[0171] Step S13: The spray device is controlled to spray detergent onto the clothes to be washed in the inner tub 1.

[0172] Preferably, first, steps S11 and S12 are repeated multiple times to immerse the garment to be washed, and then steps S12 and S13 are repeated multiple times to allow the detergent to adhere to the garment.

[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. This cycle is repeated multiple times until a preset amount and number of sprays of water 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. This cycle is repeated multiple times until a preset amount and number of sprays of detergent are reached.

[0174] Of course, during the execution of steps S11 and S12 once, the water spray and the rotation of the inner tub 1 may be controlled to occur simultaneously, or the inner tub 1 may be controlled to rotate first, and then the water spray may be controlled. Similarly, during the execution of steps S12 and S13 once, the detergent spray and the rotation of the inner tub 1 may be controlled to occur simultaneously, or the inner tub 1 may be controlled to rotate first, and then the detergent spray 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 undiluted detergent or a mixture of undiluted detergent and water, but the present invention is not limited thereto. For example, one may first spray water onto the garment to be washed, soaking the garment completely, and then spray a high-concentration detergent onto the garment to allow the detergent to adhere to it. Alternatively, one may first spray water onto the garment to be washed, wetting the garment, and then spray a low-concentration detergent onto the garment, soaking the garment completely to allow the detergent to adhere to it. This method allows the garment to be wet first but not completely immersed, and then thoroughly immersed under the action of the detergent, enabling the detergent to adhere to the garment more effectively and uniformly, ensuring the subsequent garment washing effect, while also saving on the amount of detergent and spray water used.

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

[0177] Step S131: The spray device is controlled to spray a mixed solution of detergent and water onto the clothes to be washed in the inner tub 1.

[0178] In step S2, by employing a rinsing method that controls the alternating spraying and rotation of the inner tub 1, the clothes to be washed are dispersed as the inner tub 1 rotates, preventing the clothes from overlapping and allowing the mixed solution sprayed onto the clothes to be washed to be sprayed more uniformly. At the same time, a point-and-move water supply system is formed, ensuring the accuracy of the water level entering the gap cavity, thus ensuring precise control of drainage and preventing contact between the water in the inner tub 1 and the water in the gap cavity due to delays in drainage.

[0179] After each rinse cycle, 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 system detects that the clothes have finished rinsing and stops.

[0180] Step S3 specifically includes the following steps:

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

[0182] In step S32, if the actual water level is higher than the preset water level, the gap cavity 4 is controlled to drain the water so that the water in the gap cavity 4 does not always come into contact with the inner tank 1.

[0183] In this embodiment, a water level sensor (not shown) is provided inside the gap cavity 4 to detect the actual water level inside the gap cavity 4. The preset water level is always such that the water level does not 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 kept 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 program. Maintaining the drained state of the gap cavity 4 can be achieved by keeping the drain port communicating with the gap cavity 4 open at all times and draining using the principle of gravity drainage. Alternatively, this can be achieved by keeping the drain pump of the drain pipe communicating with the gap cavity 4 constantly on and draining using the principle of powered drainage.

[0186] Throughout the entire washing program, the spray device directly sprays the clothes to be washed into the inner tub 1. The sprayed water and / or detergent first enter the inner tub 1, come into contact with the clothes, then enter the gap cavity 4, and finally exit the gap cavity 4. This ensures that the water and / or detergent sprayed onto the clothes remains clean at all times. Simultaneously, the liquid in the gap cavity 4 never comes 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, preventing bacteria from being carried into the inner tub 1 and adhering to the clothes, thus preventing secondary contamination. Furthermore, because the water in the gap cavity 4 never comes into contact with the inner tub 1, the inner tub 1 does not need to overcome resistance from water contact during rotation, resulting in lower power consumption compared to conventional washing equipment. Additionally, employing a spray mode for washing clothes allows for more uniform spraying of the liquid onto the clothes, ensuring effective cleaning while also providing water savings.

[0187] In step S3, "throughout the entire process" refers to the execution of the entire washing process, including the rinsing and dewatering stages in addition to the washing stage.

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

[0189] Step S110: The spray device is controlled to spray detergent onto the clothes to be washed in the inner tub 1.

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

[0191] Step S130: The spray device is controlled to spray water onto the clothes to be washed in the inner tub 1.

[0192] Preferably, first, steps S110 and S120 are repeated multiple times to allow the detergent to adhere to the garment to be washed, and then steps S120 and S130 are repeated multiple times to immerse the garment.

[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. This cycle is repeated multiple times until the preset amount and number of sprays of detergent 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. This cycle is repeated multiple times until the preset amount and number of sprays of water are reached.

[0194] Of course, during a single execution of steps S110 and S120, the detergent spray and the rotation of the inner tub 1 may be controlled simultaneously, or the inner tub 1 may be controlled to rotate first, and then the detergent spray may be controlled. Similarly, during a single execution of steps S120 and S130, the water spray and the rotation of the inner tub 1 may be controlled simultaneously, or the inner tub 1 may be controlled to rotate first, and then the water spray 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.

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

[0196] Step S1101: The spray device is controlled to spray a mixed solution of detergent and water onto the clothes to be washed in the inner tub 1.

[0197] Fourth embodiment In the cleaning stage, step S1 specifically includes the following steps, which is different from the second embodiment.

[0198] Step S1100: The spray device is controlled to spray a mixed solution 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 executed alternately and repeated multiple times until the preset spray volume and number of sprays are reached.

[0201] In the above steps, by employing a method of washing by alternately controlling the spray and the rotation of the inner tub 1, the clothes to be washed are dispersed when the inner tub 1 rotates, preventing the clothes from overlapping and allowing the mixed solution sprayed onto the clothes to be washed to be sprayed more uniformly. At the same time, a point-and-move water supply system is formed, ensuring the accuracy of the water level entering the gap cavity 4, thereby ensuring precise control of drainage and preventing contact between the water in the inner tub 1 and the water in the gap cavity 4 due to delays in drainage.

[0202] Fifth embodiment In the cleaning stage, step S1 differs from the second embodiment in that it specifically 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 inside the inner tub 1 are sufficiently wet, 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 mixed solution of detergent and water onto the clothes to be washed in the inner tub 1.

[0208] Sixth embodiment In the cleaning stage, step S1 differs from the second embodiment in that it specifically 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 inside the inner tub 1 are sufficiently wet, 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 mixed solution of detergent and water onto the clothes to be washed in the inner tub 1.

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

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

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

[0217] In practice, the concentrations of the mixed solutions in the fourth and seventh embodiments are much lower than those in the second, third, fifth, and sixth embodiments. This is because, in the embodiments of the fourth and seventh embodiments, water is no longer sprayed alone, and the water necessary for cleaning is completely 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 ensures the degree of cleaning and the cleanliness of the subsequent rinsing, and the present invention does not impose any limitations thereon.

[0218] In the fifth, sixth, and seventh embodiments described above, by employing a washing mode in which the machine sprays first and then rotates, the washing machine can loosen the garments after they have sufficiently absorbed water and / or detergent, thereby ensuring a thorough cleaning. In actual operation, the washing mode in which the machine sprays first and then rotates is applied when there are only a few garments to be washed, in order to avoid uneven spraying of the garments due to too many garments, which could affect the cleaning effect.

[0219] Next, refer to Figure 7. Figure 7 is a flowchart of a possible complete procedure for the isolation cleaning control method for cleaning equipment of the present invention. As shown in Figure 7, the possible complete flow of the isolation cleaning control method for cleaning equipment of the present invention is S11-S12-S13-S2-S3.

[0220] Third technical proposal: CN202310048381.X, Figures 8-9, Eighth embodiment.

[0221] The present invention provides a method for controlling isolated washing of washing equipment. In this 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. Here, the structure of the drum-type washing machine can be understood in combination with the structure described in the second embodiment.

[0222] Refer to Figure 8. Figure 8 is a flowchart of the main steps of the isolation cleaning control method for cleaning equipment of the present invention, which is used throughout the cleaning process of cleaning equipment, and which includes all the operations of washing, rinsing, and dewatering. 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] In step S2, water and / or detergent are sprayed onto the clothes to be washed in the inner tub 1, and at the same time, before spraying, or after spraying, hot air is supplied into the outer tub 2.

[0225] Step S3: The entire cleaning program is controlled to ensure that the water in the gap cavity 4 does not always come into contact with the inner tank 1.

[0226] In this embodiment of the present invention, the spray device sprays directly onto the clothes to be washed in the inner tub 1 throughout the entire washing program. This ensures that the sprayed water and / or detergent first enters the inner tub 1 and comes into contact with the clothes, then enters the gap cavity 4, and finally is discharged from the 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 the gap cavity 4 never comes into contact with the inner tub. As the inner tub 1 rotates, the water in the gap cavity 4 does not re-enter the inner tub 1 with the rotation, preventing bacteria in the gap cavity 4 from being brought into the inner tub 1 and adhering to the clothes, thus preventing secondary contamination of the clothes. Furthermore, because the water in the gap cavity 4 never comes into contact with the inner tub 1, there is no need to overcome resistance due to contact with water when the inner tub 1 rotates, thus reducing power consumption compared to conventional drum-type washing machines. Moreover, by employing a spray mode to wash clothes, water and / or detergent can be sprayed more uniformly onto the clothes, ensuring a thorough cleaning while also providing a water-saving effect.

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

[0228] The garments 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 garments to be washed in the inner tub 1 and controlling the inner tub 1 to rotate it. Specifically, first, the process of controlling the spray device to spray water onto the garments 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 garments 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] The above description relates to the alternating operation of the inner tub 1 and the spray device, but is not limited to this. Those skilled in the art may, depending on their needs, control the inner tub 1 to reciprocate while the spray device sprays water and / or detergent, or control the inner tub 1 to reciprocate after the clothes to be washed have been sufficiently wet. These adjustments do not depart from the principles of the present invention and are therefore 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 first controlling the spray device to spray water onto the clothes to be washed in the inner tub 1 to wet the clothes, and then controlling the spray device to spray detergent onto the clothes to be washed in the inner tub 1 to allow the detergent to adhere to the clothes.

[0231] The above-mentioned detergent may be a single detergent, such as a laundry detergent, or a detergent mixture having a certain concentration after dilution; the present invention is not limited to these.

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

[0233] In step S11, water is sprayed onto the clothes to be washed inside 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, step S1 in the rinsing stage specifically includes the following steps:

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

[0236] In an embodiment of the present invention, during the rinsing stage, after each rinse is completed, 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 tub stops when it is detected that the clothes have finished rinsing.

[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 tank. The heating rate can be improved by adding an electric heating drying system to the heat pump drying system. The step of "supplying hot air into the outer tank 2" in step S2 specifically includes the following steps:

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

[0239] In the embodiments of the present invention, by supplying hot air to fumigate the clothes, the enzymes contained in the detergent introduced into the inner tub 1 are activated during the washing stage, allowing them to better blend with the clothes and promote dirt removal and cleaning. At the same time, the amount of detergent used can be reduced, the number of rinses can be reduced, and the clothes can be rinsed more easily during the rinsing stage, thereby improving the degree of cleaning and cleanliness. Furthermore, because the clothes are in a steam environment, the clothes can be heated more uniformly compared to clothes immersed in water in conventional methods, resulting in higher energy transfer efficiency. At the same time, the environment of the inner tub 1 and the clothes can be sterilized and disinfected while washing.

[0240] Furthermore, in order to ensure the heat transfer efficiency of the hot air, improve energy utilization, rapidly raise the temperature of the clothes during the washing process, and reduce the frequent operation of the drying system which can lead to a decrease in component lifespan, in the embodiment of the present invention, the drying system is first controlled and started, rapidly heated 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 clothes and the better the corresponding water absorption of the material of the clothes, the higher the set upper temperature limit. Next, the clothes are heated using the 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 and started again, and if the actual temperature reaches or exceeds the set temperature, the drying system is controlled and stopped. Furthermore, in the case of a washer-dryer combined washing machine, if the user requests drying, the clothes are first heated after the spin cycle is complete before entering the drying program, 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 ensure that the water in the gap cavity 4 does not constantly come into contact with the inner tank.

[0242] Step S3 specifically includes the following steps:

[0243] In step S31, the actual water level in the gap cavity 4 is obtained in real time throughout the entire cleaning program.

[0244] In step S32, if the actual water level is higher than the preset water level, the gap cavity 4 is controlled to drain the water so that the water in the gap cavity 4 does not always come into contact with the inner tank 1.

[0245] In an 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 always a water level that does not 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] In step S33, the gap cavity 4 is kept 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 embodiments of the present invention, maintaining the drainage state of the gap cavity 4 can be achieved by keeping the drain port communicating with the gap cavity 4 open at all times and draining using the principle of gravity drainage. Alternatively, this can also be achieved by keeping the drain pump of the drain pipe communicating with the gap cavity 4 constantly on and draining using the principle of powered drainage.

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

[0250] In step S4, before the spray device is activated, a normal cleaning water supply is performed to obtain the actual water level change ΔL in the gap cavity 4.

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

[0252] Step S4 specifically includes the following steps:

[0253] Step S41: Drain the gap cavity 4 until it is empty and obtain the first water level L1.

[0254] In step S42, water is supplied to the gap cavity 4 at a predetermined time t1 to obtain a second water level L2.

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

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

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

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

[0259] Step S6: Before the spraying device is activated, obtain the weight and / or material of the garments to be washed in the inner tub 1.

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

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

[0262] In step S7, a person skilled in the art would pre-store a mapping relationship between different garment materials and weights and the amount of water and / or detergent sprayed, and then match the corresponding amount of water and / or detergent sprayed based on the weight and / or material of the garment to be cleaned. For example, the heavier the garment to be cleaned, the greater the amount of water and / or detergent sprayed and the longer the spraying time. Even at the same weight, garments of different materials will have different water absorption rates. For example, the amount of water and / or detergent sprayed required for cotton garments is greater than that required for synthetic fiber garments, and accordingly, the spraying time required for cotton garments is longer than that required for synthetic fiber garments.

[0263] In embodiments of the present invention, by controlling the amount of water and / or detergent sprayed according to the weight and / or material of the clothing to be washed, it is possible to ensure the cleaning effect of the clothing while also achieving the objective of water conservation.

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

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

[0266] Next, refer to Figure 9. Figure 9 is a flowchart of a possible complete procedure for the isolation cleaning control method for cleaning equipment of the present invention. As shown in Figure 9, the possible complete flow of the isolation cleaning control method for cleaning equipment of the present invention is S4-S5-S6-S7-S1-S2-S31-S32. Here, steps S1-S2-S31-S32 relate to all operational processes of cleaning, rinsing, and dewatering the cleaning equipment.

[0267] Based on embodiments of the above method, the present invention further provides a cleaning system including a controller, the controller configured to perform the above isolation cleaning control method.

[0268] Fourth technical proposal: CN202310338633.2, Figures 10-12, Ninth embodiment.

[0269] The present invention provides a method for controlling isolated washing of washing equipment. In this 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. Here, the structure of the drum-type washing machine can be understood in combination with the structure described in the second embodiment.

[0270] Next, refer to Figure 11. Figure 11 is a flowchart of the main steps of the isolation cleaning control method for the cleaning equipment of the present invention. As shown in Figure 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] In step S2, when the spray device stops spraying water and / or detergent onto the clothes to be washed in the inner tub and the crevice cavity stops draining, steam is supplied to the outer tub.

[0273] Step S3: The program controls the water in the gap cavity 4 so that it does not always come into contact with the inner tank 1.

[0274] Note that "throughout the entire process" in step S3 refers to the execution of the entire washing process, including the rinsing and dewatering stages in addition to the washing stage.

[0275] In this embodiment of the present invention, the spray device sprays directly onto the clothes to be washed in the inner tub 1 throughout the entire washing program. This ensures that the sprayed water and / or detergent first enters the inner tub 1 and comes into contact with the clothes, then enters the gap cavity 4, and finally is discharged from the 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 the gap cavity 4 never comes 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 with the rotation, preventing bacteria in the gap cavity 4 from being brought into the inner tub 1 and adhering to the clothes, thus preventing secondary contamination of the clothes. Furthermore, because the water in the gap cavity 4 never comes into contact with the inner tub 1, there is no need to overcome resistance due to contact with water when the inner tub 1 rotates, thus reducing power consumption compared to conventional drum-type washing machines. Moreover, by employing a spray mode to wash clothes, water and / or detergent can be sprayed more uniformly onto the clothes, ensuring a thorough cleaning while also providing a water-saving effect.

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

[0277] The garments 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 garments to be washed in the inner tub 1 and controlling the inner tub 1 to rotate it. Specifically, first, the process of controlling the spray device to spray water onto the garments 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 garments 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] Note that the above description is made in relation to the alternating operation of the inner tub 1 and the spray device, but this is not limiting. Those skilled in the art can, according to needs, control the inner tub 1 to reciprocate and rotate simultaneously while the spray device sprays water and / or detergent, or can control the inner tub 1 to reciprocate and rotate after the clothing to be cleaned is first sufficiently wetted. Since these above adjustments do not deviate from the principle of the present invention, they are also included within the protection scope of the present invention.

[0279] Here, the step of controlling the spray device to spray water and / or detergent onto the clothing to be cleaned in the inner tub 1 specifically includes the following steps. First, control the spray device to spray water onto the clothing to be cleaned in the inner tub 1 to wet the clothing to be cleaned, and then control the spray device to spray detergent onto the clothing to be cleaned in the inner tub 1 to attach the detergent to the clothing to be cleaned.

[0280] Note that the above detergent may be a single detergent, such as a laundry detergent, or may be 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] Step S11, while spraying water onto the clothing to be cleaned in the inner tub 1, control the inner tub 1 to reciprocate and rotate.

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

[0284] Step S12, alternately perform the operation of spraying water onto the clothing to be cleaned in the inner tub 1 and the operation of controlling the inner tub 1 to reciprocate and rotate.

[0285] In an embodiment of the present invention, in the rinsing stage, every time the rinsing is completed once, the inner tub 1 is rotated at a high speed to dehydrate the water on the clothes, and then the next rinsing is performed. This cycle is repeated multiple times until the set number of rinsing times is completed or it is detected that the clothes have finished rinsing and then stopped.

[0286] As shown in FIG. 10, the cleaning equipment further includes a heating element 5 provided at the inner bottom of the outer tub 2. A groove 21 is provided at the inner bottom of the outer tub 2, and the heating element 5 is an electric heating tube provided in the groove 21. The step of "supplying water vapor into the outer tub 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 tub 2 to generate water vapor.

[0287] In an embodiment of the present invention, by supplying steam to fumigate the clothes, in the cleaning stage, the enzyme contained in the detergent put into the inner tub 1 can be activated, better fused with the clothes, and promote the removal of dirt and cleaning. At the same time, the amount of detergent used can be reduced, the number of rinsing times can be reduced, and the clothes are more easily rinsed cleanly in the rinsing stage, and the cleaning cleanliness can be improved. Also, because the clothes are in a steam environment, compared with the clothes immersed in conventional water, the clothes can be heated more uniformly, the energy transfer efficiency can be increased, and at the same time, the environment of the inner tub 1 and the clothes can be sterilized and disinfected while cleaning.

[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 clothes to be cleaned in the inner tub 1, first rotate the inner tub 1.

[0290] S22, when the gap cavity 4 is in a drainage stop state, supply water vapor into the outer tub 2.

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

[0292] S23, when the gap cavity 4 is in a drained state, and at the same time as or after the gap cavity 4 stops draining, steam is supplied into the outer tank 2.

[0293] In the above steps, the heating element 5 does not operate when the cleaning equipment is either supplying or draining water. In other words, no steam is supplied into the outer tank 2 at this time. This is because when the cleaning equipment is supplying or draining water, the cleaning water level in the gap cavity 4 is unstable, and heating at this time would result in the discharge of freshly heated cleaning water when draining, or insufficient heating temperature when supplying water, preventing the generation of steam and thus preventing the continuation of heating. This would lead to energy waste and prevent the maximum utilization of energy. Therefore, in order to improve energy utilization, the cleaning equipment of the present invention operates the heating element 5, i.e., supplies steam into the outer tank 2, only when water supply and draining are stopped.

[0294] When steam is supplied to the outer tub 2, water droplets continue to fall into the gap cavity 4 while the wet clothes are being washed by impact, causing the water level in the gap cavity 4 to rise. In order 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 sufficient water level. In this way, the water level in the gap cavity 4 becomes unstable. Therefore, in order to supply steam while the water level in the gap cavity 4 is stable, a preferred embodiment is to wash the clothes by impact for a certain period of time after the water supply to the washing equipment is complete, and then supply steam until the water level stabilizes. Specifically, in step S22, after the inner tub 1 has rotated for a certain period of time and the clothes to be washed by impact, if there is no change in the water level in the gap cavity 4, or if there is no need to control the gap cavity 4 to drain the water even if a change in the water level occurs, steam is supplied directly. In step S23, after the inner tub 1 has rotated for a certain period of time to agitate and wash the clothes to be washed, if a change in the water level in the gap cavity 4 occurs and drainage is required, steam is supplied at the same time as or after the drainage is completed.

[0295] Furthermore, in order to ensure the heat transfer efficiency of the steam when supplying steam, to rapidly raise the temperature of the clothes during the washing process, and to reduce the frequent heating of the heating element 5 which leads to a decrease in component lifespan, in the embodiment of the present invention, the heating element 5 is first controlled and started, and after rapidly heating to a temperature range in which the steam can rapidly volatilize, the heating is stopped. Here, the rapid volatilization temperature range is, for example, 70°C to 90°C, and the selection of this temperature range depends on the weight of the clothes to be washed, with the heavier the weight of the clothes to be washed, the higher the upper limit of the set rapid volatilization temperature. Next, the clothes are heated using the 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 heating element 5 is controlled and operated again, and if the actual temperature reaches or exceeds the set temperature, the heating element 5 is controlled and the heating is stopped. Furthermore, in the case of a washer-dryer integrated washing machine, if the user requests drying, after the spin-drying is completed, the clothes are first steam-heated before entering the drying program, which increases the surface temperature of the clothes and improves drying efficiency.

[0296] Step S3 specifically includes the following steps:

[0297] In step S31, the actual water level in the gap cavity 4 is obtained in real time throughout the entire cleaning program.

[0298] In step S32, if the actual water level is higher than the preset water level, the gap cavity 4 is controlled to drain the water so that the water in the gap cavity 4 does not always come into contact with the inner tank 1.

[0299] In an 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 always a water level that does not come into contact with the edge of the inner tank 1.

[0300] Preferably, in step S32, the step of "controlling the gap cavity 4 to drain" further includes the following steps.

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

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

[0303] Step 3211: Control to drain the gap cavity 4 for a first preset time.

[0304] Step 3212: Control to stop draining the gap cavity 4 for a second preset time.

[0305] In the above steps, when the water level in the gap cavity rises, by intermittently draining from the gap cavity 4, a jogging drainage method is formed to prevent the cleaning water in the gap cavity 4 from becoming empty and prevent the occurrence of siphon phenomenon. Exemplarily, the first preset time is 1.5 s, and the second preset time is 3 s.

[0306] In an embodiment of the present invention, by intermittently operating the drainage pump of the drainage pipe communicating with the gap cavity 4, drainage is performed using the principle of powered drainage.

[0307] In an embodiment of the present invention, by controlling the spray amount of water and / or detergent according to the weight and / or material of the clothes to be cleaned, the cleaning effect of the clothes can be ensured, and the purpose of water conservation can also be achieved.

[0308] Furthermore, according to the weight and / or material of the clothes to be cleaned, the number of washing times and the number of rinsing times can also be controlled. The user can also customize the number of washing times and / or the number of rinsing times according to the actual washing needs.

[0309] After rinsing, the user can select whether to dry the clothes according to the needs.

[0310] Next, refer to Figure 12. Figure 12 is a flowchart of a possible complete procedure for the isolation cleaning control method for cleaning equipment of the present invention. As shown in Figure 12, the possible complete flow of the isolation cleaning control method for cleaning equipment of the present invention is as follows:

[0316] S104 acquires the actual water level in the gap cavity 4 in real time.

[0317] S105 determines whether the actual water level is higher than the pre-set water level.

[0318] If the answer is "Yes", then step S106 is executed.

[0320] S106, control the gap cavity to drain for a first preset time.

[0321] S107, control the gap cavity to stop draining for a second preset time.
