[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 and wash them. When a washing machine is used for a long time, bacteria inevitably grow between the inner and outer tubs, which can cause cross-contamination of 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.

[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, 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 is discharged from the gap cavity. This ensures that the water and / or detergent sprayed onto the clothes to be washed is always clean and is not reused. At the same time, the water in the gap cavity does not always come into contact with the inner tub, and when the inner tub rotates, the water in the gap cavity does not enter the inner tub again as the inner tub rotates, preventing bacteria in the gap cavity from being brought into the inner tub and adhering to the clothes to be washed, and not causing secondary contamination of the clothes. Furthermore, since the water in the gap cavity is not constantly in contact with the inner tub, the inner tub does not need to overcome resistance caused by contact with water when rotating, thereby reducing power consumption compared to conventional drum-type washing machines.

[0067] First technical proposal: CN202211543213.X, Figures 1 to 4, first embodiment.

[0068] 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 mounted within the outer tub 2, the inner tub 1 is used to accommodate 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 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 within the inner tub 1 so as to be able to spray.

[0069] 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:

[0070] 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.

[0071] Step S2: When the spray device is started, the actual water level in the gap cavity is obtained.

[0072] 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.

[0073] Here, a water level sensor (not shown) is provided in the gap cavity to detect the actual water level in the gap cavity.

[0074] 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 in the gap cavity 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 and causing secondary contamination of the clothes. Furthermore, because the water in the gap cavity does not always come into contact with inner tub 1, the 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.

[0075] 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 effectiveness of washing and rinsing clothes while also saving water.

[0076] 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:

[0077] Step S11: The spray device is controlled to spray water onto the clothes to be washed in the inner tub 1.

[0078] Step S12: The inner tank 1 is controlled to rotate back and forth.

[0079] In step S13, the spray device is controlled to spray detergent onto the laundry to be washed in the inner tub 1.

[0080] 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.

[0081] 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.

[0082] 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.

[0083] Preferably, step S13 further includes the following steps:

[0084] 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.

[0085] 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.

[0086] Specifically, taking the above-mentioned detergent as an example of a single detergent, when step S13 is adopted, a person skilled in the art can adopt the following method. For example, first, water is sprayed onto the clothes to be washed until the clothes are fully soaked, and then detergent is sprayed onto the clothes to be washed so that the detergent adheres to the clothes to be washed. When step S14 is adopted, those skilled in the art can adopt the following method. For example, water is first sprayed onto the clothes to be washed to make them wet, and then a mixture of detergent and water is sprayed onto the clothes to fully soak them and allow the detergent to adhere to them. This method first wets the clothes to be washed but does not fully soak them, and allows them to fully soak under the action of the mixture of detergent and water, allowing the detergent to adhere to the clothes better and more uniformly, ensuring the subsequent washing effect of the clothes and saving the amount of detergent used and the amount of water sprayed.

[0087] Alternatively, in an alternative embodiment, step S1 specifically includes the following steps:

[0088] In step S110, the spray device is controlled to spray detergent onto the laundry to be washed in the inner tub 1.

[0089] In step S120, the inner tank 1 is controlled to rotate back and forth.

[0090] In step S130, the spray device is controlled to spray water onto the laundry to be washed in the inner tub 1.

[0091] 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.

[0092] Alternatively, in an alternative embodiment, step S110 further includes the following steps:

[0093] The spray device is controlled to spray a mixture of detergent and water onto the clothes to be washed in the inner tub 1.

[0094] Alternatively, in an alternative embodiment, step S1 specifically includes alternately performing the following steps:

[0095] 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.

[0096] In step S1200, the inner tank 1 is controlled to rotate back and forth.

[0097] The control method is used in the wash phase of a drum washing machine.

[0098] Alternatively, in an alternative embodiment, step S1 specifically includes the following steps:

[0099] First, the spray device is controlled to spray water onto the clothes to be washed in the inner tub 1.

[0100] Next, the spray device is controlled to spray detergent onto the clothes to be washed in the inner tub 1.

[0101] After the clothes to be washed in the inner tub are sufficiently wetted, the inner tub is controlled to rotate back and forth.

[0102] 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.

[0103] The spray device is controlled to spray a mixture of detergent and water onto the clothes to be washed in the inner tub 1.

[0104] 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:

[0105] First, the spray device is controlled to spray detergent onto the clothes to be washed in the inner tub 1.

[0106] Next, the spray device is controlled to spray water onto the clothes to be washed in the inner tub 1.

[0107] 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.

[0108] 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.

[0109] The spray device is controlled to spray a mixture of detergent and water onto the clothes to be washed in the inner tub 1.

[0110] 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:

[0111] 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.

[0112] 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.

[0113] Hereinafter, reference will be made to FIG. 4, which is a flowchart showing a specific procedure of step S1 of the rinsing stage in the control method for a drum type washing machine 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 the inner tub 1" specifically includes the following steps.

[0114] 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.

[0115] 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.

[0116] 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.

[0117] 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.

[0118] 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.

[0119] 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.

[0120] 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.

[0121] 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.

[0122] 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.

[0123] 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.

[0124] In the above steps, by supplying hot air or 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. At the same time, the amount of detergent used and the number of rinses can be reduced, making the clothes easier to rinse clean during the rinsing stage and improving the level of cleanliness after washing. In addition, because the clothes are in a steam environment, the clothes can be heated more evenly and energy transfer efficiency can be improved compared to clothes soaked in conventional water, and the environment of the inner tub 1 and the clothes can be sterilized and disinfected while washing.

[0125] 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.

[0126] 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:

[0127] Step S4: Normal cleaning water supply is performed, and the actual water level change ΔL in the gap cavity is obtained.

[0128] 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.

[0129] Specifically, step S4 specifically includes the following steps:

[0130] Step S41: Control the clearance cavity to drain until it is empty and obtain a first water level L1.

[0131] In step S42, water is supplied to the gap cavity for a preset time t1, and a second water level L2 is obtained.

[0132] Step S43: Calculate the actual water level change amount ΔL.

[0133] Here, the calculation formula for the actual water level change ΔL is as follows: [Formula 1] ΔL=(L2-L1) / t1

[0134] In the above steps, the present invention detects the water pressure condition using the amount of change in water level, thereby achieving higher accuracy.

[0135] Continuing to refer to FIG. 1, before the spray device is activated, the control method of the present invention further includes the following steps:

[0136] In step S6, the weight and / or material of the clothes to be washed in the inner tub 1 is acquired.

[0137] 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.

[0138] 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.

[0139] 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 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 if the weight is the same, clothes made of different materials have different water absorption capacities. For example, the amount of water and / or detergent sprayed on cotton clothes is greater than the amount of water and / or detergent sprayed on synthetic fiber clothes, and accordingly, the time required to spray water and / or detergent on cotton clothes is longer than the time required to spray water and / or detergent on synthetic fiber clothes.

[0140] 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.

[0141] Furthermore, the number of washes and rinses can be controlled depending on the weight and / or material of the clothes being washed. Users can also customize the wash and / or rinse times according to their actual cleaning needs.

[0142] After rinsing, the user can choose whether to dry the clothes or not depending on their needs.

[0143] Second technical solution: CN202310048381.X, Figures 5 to 7, second embodiment.

[0144] The present invention provides a method for controlling isolated washing of washing equipment, and the washing equipment in the present invention may be a drum-type washing machine or a pulsator-type washing machine. Hereinafter, the control method of the present invention will be described taking 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. Figure 5 shows a clearance cavity 4 formed between the inner tub 1 and the outer tub 2. The spray device may be attached to a position other than the window packing 3, as long as it can spray inside the inner tank 1, and the present invention does not place any restrictions on the installation position of the spray device.

[0145] Please refer to Figure 6. Figure 6 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 6, the control method of the present invention includes the following steps:

[0146] 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.

[0147] 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.

[0148] 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.

[0149] In an 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, so that the sprayed water and / or detergent first enters the inner tub 1 and comes into contact with the clothes to be washed, 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 to be washed is always clean and is not reused, and at the same time, the water in the gap cavity 4 does not always come into contact with the inner tub, and when the inner tub 1 rotates, the water in the gap cavity 4 does not enter the inner tub 1 again as the inner tub 1 rotates, preventing bacteria in the gap cavity 4 from being brought into the inner tub 1 and adhering to the clothes to be washed, and not causing secondary contamination of the clothes. Furthermore, since the water in the gap cavity 4 is not constantly in contact with the inner tub 1, the inner tub 1 does not need to overcome resistance caused by contact with water when rotating, and therefore power consumption is reduced compared to conventional drum-type washing machines. Furthermore, by adopting the spray mode to wash clothes, water and / or detergent can be sprayed more evenly onto the clothes, ensuring the washing effect of the clothes while also saving water.

[0150] In the cleaning stage, step S1 specifically includes the following steps:

[0151] 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. That is, first, the spray device is controlled to spray water onto the clothes to be washed in the inner tub 1, and the inner tub 1 is controlled to rotate back and forth, and this is repeated multiple times; then the spray device is controlled to spray detergent onto the clothes to be washed in the inner tub 1, and the inner tub 1 is controlled to rotate back and forth, and this is repeated multiple times.

[0152] It should be noted that although the above description is given in relation to the alternating operation of the inner tub 1 and the spray device, this is not limiting, and those skilled in the art may, according to their needs, control the inner tub 1 to rotate back and forth while the spray device sprays water and / or detergent, or may first wet the clothes to be washed sufficiently and then control the inner tub 1 to rotate back and forth. These adjustments do not deviate from the principle of the present invention, and are therefore also included within the protection scope of the present invention.

[0153] 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, 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.

[0154] 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.

[0155] In the rinsing stage, step S1 specifically includes the following steps.

[0156] 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.

[0157] Alternatively, in an alternative embodiment, in the rinsing stage, step S1 specifically includes the following steps:

[0158] 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.

[0159] 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.

[0160] The washing facility further includes a drying system, wherein the drying system is a heat pump drying system and / or an electrically heated 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 temperature rise 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 tub 2" in step S2 specifically includes the following steps.

[0161] Step S21: Control the drying system to supply hot air into the outer tub.

[0162] 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 during the washing stage are activated, allowing the detergent 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 cleaning cleanliness. In addition, because the clothes are in a steam environment, they can be heated more evenly and the energy transfer efficiency can be increased compared to conventional clothes soaked in water, while the environment of the inner tub 1 and the clothes can be sterilized and disinfected while washing.

[0163] Furthermore, in order to ensure the heat transfer efficiency of the hot air, improve energy utilization, quickly raise the temperature of the clothes during the washing process, and reduce the frequent operation of the drying system which leads to a shortened component life, in an embodiment of the present invention, the drying system is first controlled and started, and then heating is stopped after quickly heating to the set temperature range. The temperature range is determined depending on the weight and material of the clothes to be washed, and the heavier the clothes to be washed and the better the water absorbency of the material of the clothes to be washed, the higher the set upper temperature limit. The residual heat in the tub is then 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 drying system is controlled to operate 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 washing machine with a built-in washer / dryer, if the user requests drying, the clothes can be heated first after the spin cycle is completed and then the drying program can be started, thereby raising the surface temperature of the clothes and improving drying efficiency.

[0164] 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.

[0165] Specifically, step S3 includes the following steps.

[0166] Step S31: Obtain the actual water level height in the gap cavity 4 in real time throughout the entire cleaning program.

[0167] 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.

[0168] 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.

[0169] Alternatively, in an alternative embodiment, step S3 specifically includes the following steps:

[0170] 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.

[0171] In an 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 the air by utilizing the principle of gravity drainage. It can also be achieved by constantly turning on the drain pump of the drain pipe communicating with the gap cavity 4 and using the principle of power drainage to drain the water.

[0172] 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:

[0173] 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.

[0174] 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.

[0175] Specifically, step S4 includes the following steps.

[0176] Step S41: Drain the clearance cavity 4 to empty it and obtain a first water level L1.

[0177] In step S42, water is supplied to the gap cavity 4 for a preset time t1, and a second water level L2 is obtained.

[0178] Step S43: Calculate the actual water level change ΔL.

[0179] Here, the calculation formula for the actual water level change ΔL is as follows: [Formula 2] ΔL=(L2-L1) / t1

[0180] 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.

[0181] Before step S1, the control method of the present invention further includes the following steps.

[0182] 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.

[0183] Step S7: Control the amount of water and / or detergent sprayed depending on the weight and / or material of the clothes to be washed.

[0184] 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.

[0185] In step S7, the person skilled in the art pre-stores the mapping relationship between different materials and weights of clothes and the amount of water and / or detergent sprayed, and then matches the corresponding amount of water and / or detergent sprayed based on the weight and / or material of the clothes to be washed that are actually obtained. For example, the heavier the weight of the clothes to be washed, the greater the amount of water and / or detergent sprayed and the longer the spray time. Clothes of the same weight but 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 time required to spray water and / or detergent on cotton clothes is longer than the time required to spray water and / or detergent on synthetic clothes.

[0186] 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.

[0187] 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.

[0188] After rinsing, the user can choose whether to dry the clothes or not depending on their needs.

[0189] Next, reference is made to FIG. FIG. 7 is a flowchart showing the overall procedure of the method for controlling isolated cleaning of a cleaning facility according to the present invention. As shown in FIG. 7, the overall flow of the method for controlling isolated cleaning of a cleaning facility of the present invention is S4-S5-S6-S7-S1-S2-S31-S32. Here, steps S1-S2-S31-S32 involve all the operation processes of the washing equipment, including washing, rinsing and dehydration.

[0190] 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.

[0191] Third technical solution: CN202310048382.4, Figures 8 to 10, third embodiment.

[0192] The present invention provides an isolated washing control method for a washing machine, and in the present invention, the washing 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. Here, the structure of the drum-type washing machine can be understood in combination with the structure described in the second embodiment. Figure 5 shows a clearance cavity 4 formed between the inner tub 1 and the outer tub 2. The spray device may be attached to a position other than the window packing 3, as long as it can spray inside the inner tank 1, and the present invention does not place any restrictions on the installation position of the spray device.

[0193] Please refer to Figure 9. Figure 9 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, and this cleaning process includes all the operation processes of washing, rinsing and spin-drying. As shown in FIG. 9, the control method of the present invention includes the following steps:

[0194] 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.

[0195] In step S2, water and / or detergent is sprayed onto the laundry to be washed in the inner tub 1, and simultaneously, before or after the spraying, water vapor is supplied into the outer tub 2.

[0196] 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.

[0197] In an 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, so that the sprayed water and / or detergent first enters the inner tub 1 and comes into contact with the clothes to be washed, 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 to be washed is always clean and is not reused, and at the same time, the water in the gap cavity 4 does not always come into contact with the inner tub, and when the inner tub 1 rotates, the water in the gap cavity 4 does not enter the inner tub 1 again as the inner tub 1 rotates, preventing bacteria in the gap cavity 4 from being brought into the inner tub 1 and adhering to the clothes to be washed, and not causing secondary contamination of the clothes. Furthermore, since the water in the gap cavity 4 is not constantly in contact with the inner tub 1, the inner tub 1 does not need to overcome resistance caused by contact with water when rotating, and therefore power consumption is reduced compared to conventional drum-type washing machines. Furthermore, by adopting the spray mode to wash clothes, water and / or detergent can be sprayed more evenly onto the clothes, ensuring the washing effect of the clothes while also saving water.

[0198] In the cleaning stage, step S1 specifically includes the following steps:

[0199] 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. That is, first, the spray device is controlled to spray water onto the clothes to be washed in the inner tub 1, and the inner tub 1 is controlled to rotate back and forth, and this is repeated multiple times; then the spray device is controlled to spray detergent onto the clothes to be washed in the inner tub 1, and the inner tub 1 is controlled to rotate back and forth, and this is repeated multiple times.

[0200] It should be noted that although the above description is given in relation to the alternating operation of the inner tub 1 and the spray device, this is not limiting, and those skilled in the art may, according to their needs, control the inner tub 1 to rotate back and forth while the spray device sprays water and / or detergent, or may first wet the clothes to be washed sufficiently and then control the inner tub 1 to rotate back and forth. These adjustments do not deviate from the principle of the present invention, and are therefore also included within the protection scope of the present invention.

[0201] 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, 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.

[0202] 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.

[0203] In the rinsing stage, step S1 specifically includes the following steps.

[0204] 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.

[0205] Alternatively, in an alternative embodiment, in the rinsing stage, step S1 specifically includes the following steps:

[0206] 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.

[0207] 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.

[0208] As shown in FIG. 8, the cleaning equipment further includes a heating element 5 provided on the inner bottom of the outer tank 2, and a groove 21 is provided on 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 water vapor into the outer tank 2" in step S2 specifically includes the following steps.

[0209] This is a step in which the heating element 5 is controlled to heat the cleaning water at the inner bottom of the outer tank 2 to generate steam.

[0210] In an embodiment of the present invention, by supplying water vapor to fumigate the clothes, the enzymes contained in the detergent added to the inner tub 1 during the washing stage can be activated, allowing the detergent 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 cleaning cleanliness. In addition, because the clothes are in a steam environment, they can be heated more evenly and the energy transfer efficiency can be increased compared to conventional clothes soaked in water, while the environment of the inner tub 1 and the clothes can be sterilized and disinfected while washing.

[0211] Furthermore, to ensure the heat transfer efficiency of water vapor, improve energy utilization, 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 parts, in this embodiment of the present invention, the heating element 5 is first controlled to start and quickly heat up to a temperature range where water vapor can be rapidly evaporated, and then heating is stopped. Here, the rapid evaporation 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 set upper limit of the rapid evaporation temperature. The residual heat in the tub is then 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, and if the actual temperature reaches or exceeds the set temperature, the heating element 5 is controlled to stop heating. Furthermore, in the case of an all-in-one washing and drying washing machine, if the user requests drying, after the spin cycle is completed, the clothes are first steam heated and then the drying program is started, thereby raising the surface temperature of the clothes and improving drying efficiency.

[0212] Specifically, step S3 includes the following steps.

[0213] Step S31: Obtain the actual water level height in the gap cavity 4 in real time throughout the entire cleaning program.

[0214] 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.

[0215] 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.

[0216] Alternatively, in an alternative embodiment, step S3 specifically includes the following steps:

[0217] 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.

[0218] 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.

[0219] 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:

[0220] 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.

[0221] 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.

[0222] Specifically, step S4 includes the following steps.

[0223] Step S41: Drain the clearance cavity 4 to empty it and obtain a first water level L1.

[0224] In step S42, water is supplied to the gap cavity 4 for a preset time t1, and a second water level L2 is obtained.

[0225] Step S43: Calculate the actual water level change amount ΔL.

[0226] Here, the calculation formula for the actual water level change ΔL is as follows: [Formula 3] ΔL=(L2-L1) / t1

[0227] 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.

[0228] Before step S1, the control method of the present invention further includes the following steps.

[0229] 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.

[0230] Step S7: Control the amount of water and / or detergent sprayed depending on the weight and / or material of the clothes to be washed.

[0231] 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.

[0232] In step S7, the person skilled in the art pre-stores the mapping relationship between different materials and weights of clothes and the amount of water and / or detergent sprayed, and then matches the corresponding amount of water and / or detergent sprayed based on the weight and / or material of the clothes to be washed that are actually obtained. Illustratively, the heavier the weight of the laundry being washed, the greater the amount of water and / or detergent spray required and the longer the spray time. Even if the weight is the same, clothes made of different materials have different water absorption capacities. For example, the amount of water and / or detergent sprayed on cotton clothes is greater than the amount of water and / or detergent sprayed on synthetic fiber clothes, and accordingly, the time required to spray water and / or detergent on cotton clothes is longer than the time required to spray water and / or detergent on synthetic fiber clothes.

[0233] 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.

[0234] 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.

[0235] After rinsing, the user can choose whether to dry the clothes or not depending on their needs.

[0236] Next, refer to FIG. FIG. 10 is a flowchart showing the overall procedure of the method for controlling isolated cleaning of a cleaning facility according to the present invention. As shown in FIG. 10, the overall flow of the method for controlling isolated cleaning of a cleaning facility of the present invention is S4-S5-S6-S7-S1-S2-S31-S32. Here, steps S1-S2-S31-S32 involve all the operation processes of the washing equipment, including washing, rinsing and dehydration.

[0237] 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.

[0238] Although the technical solutions of the present invention have been described above in combination with the preferred embodiments illustrated in the drawings, those skilled in the art will readily understand that the protection scope of the present invention is not limited to these specific embodiments. Without departing from the principle of the present invention, those skilled in the art may make equivalent modifications or substitutions to the relevant technical features, and all of these modified or substituted technical solutions fall within the protection scope of the present invention.
