Description

Technical Field

[0001] The present invention belongs to the technical field of washing equipment, and in particular, relates to a washing equipment and a self-cleaning control method thereof. Background Art

[0002] With the improvement of people's living standards, the application of washing equipment has become very popular. With the long-term use of washing equipment, some stains will adhere to the space between the inner drum and the outer drum. During the washing process, due to the lack of strong water flow, deposited dirt will form on the outer wall of the inner drum and the inner wall of the outer drum. Since the inside of the washing equipment is humid, the dirt breeds bacteria in a humid environment, becoming a hotbed for bacteria to multiply in large numbers, thus causing secondary contamination of the laundry when the user washes it next time.

[0003] At present, the method of removing dirt in washing equipment is generally to use a drum cleaner, which is added into the washing equipment and mixed evenly with the washing water, and the drum is cleaned by rotating the inner drum. However, since the detergent has been fully dissolved in a large amount of water, this method requires soaking and washing for a long time, and the cleaning effect is weak and indirect. Some washing equipment has added a spray device to rinse the dirt. Since the dirt has hardened on the washing drum, it is still necessary to mix the drum cleaner with the washing water and soak for a long time to soften the dirt in the early stage to ensure the effect of the spray. There are still technical problems such as long cleaning time, high water consumption and poor cleaning effect.

[0004] The above information disclosed in the background technology is only used to increase the understanding of the background technology of the present application, and therefore, it may include information that does not constitute the prior art known to ordinary technicians in the field.

[0012] In the washing equipment as described above, the control device is used to control the rotation of the inner drum and control the drum detergent dispensing device not to dispense drum detergent during the process of controlling the water inlet pipe to fill the water to the rinsing water level; after the water inlet pipe fills the water to the rinsing water level, the control device is used to control the water inlet pipe to stop filling the water and control the inner drum to rotate at the rinsing set start / stop timing to set the rinsing time.

[0017] The self-cleaning control method of the washing equipment of the present invention is as follows: in the process of controlling the water inlet of the water inlet pipeline, the inner drum is controlled to rotate, and the pipeline switching device is controlled to operate so that the water inlet pipeline and the flushing component are in the first conductive state or the second conductive state. When the pipeline switching device of the present invention controls the operation of the first conductive state, the front flushing component sprays clean water and the rear flushing component sprays the barrel detergent in the rotation direction of the inner drum so that the washing drum is first wetted and then sprayed with the barrel detergent, so that a high concentration of barrel detergent is attached to the washing drum, which greatly improves the cleaning effect of the barrel detergent; when the pipeline switching device of the present invention controls the operation of the second conductive state, the front flushing component sprays the barrel detergent to the washing drum in the rotation direction of the inner drum, and the rear flushing component sprays clean water to the washing drum with detergent, so as to achieve the washing effect of the detergent and water flushing together, first cleaning and then flushing, and achieving the effect of continuously ablating stains.

[0031] A washing device and a self-cleaning control method thereof, the washing device comprising an inner drum, an outer drum, at least two groups of flushing components, at least two water inlet pipes, a pipe switching device and a control device, the flushing components comprising a front flushing component and a rear flushing component arranged in the rotation direction of the inner drum; the water inlet pipe comprising a common water inlet pipe and a detergent water inlet pipe connected to a drum detergent dispensing device; the pipe switching device is used to switch the water inlet pipe and the flushing component to a first conduction state in which the common water inlet pipe is connected to the front flushing component and the detergent water inlet pipe is connected to the rear flushing component, or to a second conduction state in which the common water inlet pipe is connected to the rear flushing component and the detergent water inlet pipe is connected to the front flushing component; the control device is used to control the action of the pipe switching device to make the water inlet pipe and the flushing component in the first conduction state or the second conduction state. When the control line switching device is operated to the first conduction state, the front flushing component sprays clean water and the rear flushing component sprays the tub detergent in the rotation direction of the inner drum so that the washing drum is first wetted and then sprayed with the tub detergent, so that a high concentration of tub detergent is attached to the washing drum, improving the cleaning effect of the tub detergent; when the control line switching device is operated to the second conduction state, the front flushing component sprays the tub detergent to the washing drum in the rotation direction of the inner drum, and the rear flushing component sprays clean water to the washing drum with the detergent, so as to achieve the washing effect of the detergent and water flushing together, first cleaning and then flushing, and achieving the effect of continuously removing stains. Therefore, the washing device and the control method thereof improve the cleaning effect of self-cleaning, while shortening the self-cleaning time and reducing water consumption.

[0032] The washing equipment may be a washing machine (including a drum washing machine and a pulsator washing machine), a washer-dryer, a shoe washing machine with an inner washing drum and an outer washing drum, etc.

[0033] Taking a drum washing machine as an example, the washing device and its self-cleaning control method are specifically described below: like Figure 1-4 As shown, the drum washing machine comprises an inner drum 3 and an outer drum 2. The inner drum 3 is located inside the outer drum 2 and can rotate under the drive of an inner drum driving device.

[0034] The drum washing machine comprises at least two groups of flushing components 1 and at least two water inlet pipes 4 , wherein the number of the flushing components 1 matches the number of the water inlet pipes 4 .

[0035] At least two groups of flushing assemblies 1 are arranged in the rotation direction of the inner tub 3 so that the multiple groups of flushing assemblies 1 can flush the washing tub in sequence during the rotation of the inner tub 3 .

[0036] The flushing assembly 1 includes a front flushing assembly and a rear flushing assembly arranged in the rotation direction of the inner drum.

[0037] Among them, the front flushing component can be the front flushing component or the front flushing components in the rotation direction of the inner drum, and the rear flushing component can be the rear flushing component or the rear flushing components in the rotation direction of the inner drum.

[0038] The front flushing assembly and the rear flushing assembly are determined according to the rotation direction of the inner drum.

[0039] Specifically, in this embodiment, the flushing assembly 1 includes a first flushing assembly 111 and a second flushing assembly 112 .

[0040] In the direction facing the inner tube mouth, the inner tube includes a second flushing assembly 112 located in front and a first flushing assembly 111 located behind the second flushing assembly 112 in the clockwise direction. When the inner tube rotates clockwise, the front flushing assembly is the second flushing assembly 112 and the rear flushing assembly is the first flushing assembly 111; when the inner tube rotates counterclockwise, the front flushing assembly is the first flushing assembly 111 and the rear flushing assembly is the second flushing assembly 112. In order to improve the flushing effect, the flushing assembly 1 is a pressurized flushing assembly 1, which includes a pressurized pipeline 12 and a plurality of nozzles 13 located on the pressurized pipeline 12.

[0041] The diameter of the pressurizing pipeline 12 is smaller than the diameter of the water inlet pipeline 4 to achieve pressurization, and the nozzle 13 has a flat water outlet to achieve pressurization and increase the spraying force.

[0042] In order to fully clean the washing tub, part of the nozzles 13 are used to wash the cylindrical side walls of the inner tub 3 and the outer tub 2 , and part of the nozzles 13 are used to wash the circular bottom walls of the inner tub 3 and the outer tub 2 .

[0043] Generally, the flushing assembly 1 is disposed between the inner cylinder 3 and the outer cylinder 4 and is located at the outer edge of the circular bottom wall of the inner cylinder 3 .

[0044] Among them, the pressurized pipeline 12 includes a first pressurized pipeline 121 and a second pressurized pipeline 122 at a certain angle, one end of the first pressurized pipeline 121 is connected to the water inlet pipeline 4, and the other end of the first pressurized pipeline 121 is connected to the middle of the second pressurized pipeline 122, and the nozzle 13 is located on the second pressurized pipeline 122.

[0045] The water inlet pipeline 4 includes a common water inlet pipeline and a detergent water inlet pipeline connected to a drum detergent delivery device. At least one water inlet pipeline 4 is a detergent water inlet pipeline connected to a drum detergent delivery device to achieve delivery of drum detergent.

[0046] Specifically, in this embodiment, the water inlet pipeline 4 includes a first water inlet pipeline 41 and a second water inlet pipeline 42. The first metal pipeline 41 is a detergent water inlet pipeline connected to a drum detergent delivery device, and the second water inlet pipeline 42 is a common water inlet pipeline.

[0047] The pipeline switching device 5 is used to switch the water inlet pipeline 4 and the flushing component 1 to a first conductive state in which the ordinary water inlet pipeline is connected to the front flushing component and the detergent water inlet pipeline is connected to the rear flushing component, or a second conductive state in which the ordinary water inlet pipeline is connected to the rear flushing component and the detergent water inlet pipeline is connected to the front flushing component.

[0048] The pipeline switching device 5 is used to switch the conduction state between the water inlet pipeline 4 and the flushing component 1, so as to switch the flushing component 1 that can dispense the tub cleaner. Among them, only when the flushing component 1 is connected to the detergent water inlet pipeline 4 with the tub cleaner dispensing device, the flushing component 1 can spray the tub cleaner, and the other flushing components 1 spray clean water.

[0049] The pipeline switching device 5 is located on the water inlet pipeline 4 .

[0050] In some other embodiments, the pipeline switching device 5 may also be located between the water inlet pipeline 4 and the flushing assembly 1 .

[0051] In this embodiment, the pipeline switching device 5 is used to switch to a state where the first water inlet pipeline 41 is connected to the first flushing component 111 and the second water inlet pipeline 42 is connected to the second flushing component 112, or to switch to a state where the first water inlet pipeline 41 is connected to the second flushing component 112 and the second water inlet pipeline 42 is connected to the first flushing component 111.

[0052] In the present embodiment, the first water inlet pipe 41 is a detergent water inlet pipe connected to a drum detergent dispensing device. Therefore, when the pipe switching device 5 is switched to a state in which the first water inlet pipe 41 is connected to the first flushing component 111 and the second water inlet pipe 42 is connected to the second flushing component 112, when the drum detergent dispensing device dispenses detergent, the first flushing component 111 can spray the drum detergent, and the second flushing component 112 sprays clean water; when the pipe switching device 5 is switched to a state in which the first water inlet pipe 41 is connected to the second flushing component 112 and the second water inlet pipe 42 is connected to the first flushing component 111, when the drum detergent dispensing device dispenses detergent, the second flushing component 112 can spray the drum detergent, and the first flushing component 111 sprays clean water.

[0053] In order to save space, the pipeline switching device 5 of this embodiment includes a shell 51, a slider 52 and a slider driving device (not shown in the figure) located in the shell 51. The slider 52 has at least two groups of passages, and the slider driving device switches the passages connected to the water inlet pipeline 4 and the flushing component 1 to form at least two different connection states.

[0054] Specifically, in this embodiment, the slider 52 has a first group of passages 5211 and 5212, and the slider 52 also has a second group of passages 5221 and 5222. The slider driving device drives the slider 52 so that the first group of passages is connected to the pressurized pipeline and the flushing component or the second group of passages is connected to the pressurized pipeline and the flushing component.

[0055] When the first group of passages are connected with the pressurized pipeline and the flushing assembly, the first water inlet pipeline 41 is connected with the first flushing assembly 111, and the second water inlet pipeline 42 is connected with the second flushing assembly 112. When the second group of passages are connected with the pressurized pipeline and the flushing assembly, the first water inlet pipeline 41 is connected with the second flushing assembly 112, and the second water inlet pipeline 42 is connected with the first flushing assembly 111.

[0056] In order to ensure the accuracy of the movement of the slider 52 , the slider driving device may include a high-precision stepping motor or a cylinder. In addition, a limit block is also provided in the housing 51 .

[0057] Of course, in other embodiments, the pipeline switching device 5 may be a solenoid valve or an electrically controlled valve.

[0058] The control device is used to control the action of the pipeline switching device so that the water inlet pipeline and the flushing component are in a first conductive state or a second conductive state.

[0059] When the control line switching device is operated to the first conduction state, the front flushing component sprays clean water and the rear flushing component sprays the tub detergent in the rotation direction of the inner tub so that the washing tub is first wetted and then sprayed with the tub detergent, and a high concentration of tub detergent is attached to the washing tub, which greatly improves the cleaning effect of the tub detergent; when the control line switching device is operated to the second conduction state, the front flushing component sprays the tub detergent to the washing tub in the rotation direction of the inner tub, and the rear flushing component sprays clean water to the washing tub with the detergent, so as to achieve the washing effect of the detergent and water flushing together, first cleaning and then flushing, and achieving the effect of continuously removing stains. Therefore, the cleaning effect of self-cleaning can be improved, while shortening the self-cleaning time and reducing water consumption.

[0060] The control device is used to control the action of the pipeline switching device according to the self-cleaning water inlet stage and the inner drum rotation direction, so as to adjust the order of spraying water and spraying drum cleaning agent at different water inlet stages and different inner drum rotation directions to achieve the optimal cleaning effect.

[0061] Generally, the self-cleaning of washing equipment can be divided into a self-cleaning soaking stage, a self-cleaning washing stage and a self-cleaning rinsing stage.

[0062] Each stage includes a water intake process. The self-cleaning soaking stage requires water intake to the soaking water level for soaking, the self-cleaning washing stage requires water intake to the washing water level for washing, and the self-cleaning rinsing stage requires water intake to the rinsing water level for rinsing.

[0063] The focus of this embodiment is the control of the water inflow process at each stage.

[0064] The control device is used to control the rotation of the inner drum, control the pipeline switching device to switch to the first conduction state, and control the drum detergent dispensing device to dispense drum detergent when the washing equipment enters the self-cleaning soaking stage and controls the water inlet pipeline to flow water to the soaking water level.

[0065] During the immersion stage, as the inner drum rotates, the front flushing component first sprays a small amount of water into the washing drum in the direction of rotation of the inner drum to wet the washing drum, and the rear flushing component sprays the drum cleaner onto the washing drum. As a result, a high concentration of drum cleaner is attached to the washing drum, greatly improving the cleaning effect of the drum cleaner.

[0066] Specifically, the control device is used to control the inner drum to rotate clockwise (facing the drum mouth) when the washing device enters the self-cleaning soaking stage and controls the water inlet pipeline to flow to the soaking water level, and controls the pipeline switching device to make the front rinse component second rinse component 112 in the inner drum rotation direction communicate with the second water inlet pipeline 42, and the rear rinse component-the first rinse component 111 is connected to the detergent inlet pipeline 41, and controls the drum detergent delivery device to deliver the drum detergent, so that the clean water delivered by the second rinse component 112 first soaks the washing drum, and the drum detergent delivered by the first rinse component 111 immediately thereafter adheres to the washing drum, so that the drum detergent is fully soaked and adhered to the surface of the washing drum; control When the inner drum rotates counterclockwise, the control pipeline switching device makes the front flushing component - the first flushing component 111 in the rotation direction of the inner drum connected with the second water inlet pipeline 42, and the rear flushing component - the second flushing component 112 is connected with the detergent inlet pipeline 41, and the drum detergent dispensing device is controlled to dispense the drum detergent. Therefore, the clean water dispensed by the first flushing component 111 first soaks the washing drum, and the drum detergent dispensed by the second flushing component 112 thereafter adheres to the washing drum, so that the drum cleaning agent is fully soaked and adhered to the surface of the washing drum; therefore, during the rotation of the inner drum, the washing drum is always wetted with clean water first, and then the water added with the drum detergent is sprayed onto the washing drum to improve the cleaning effect.

[0067] After the water inlet pipe fills with water to the soaking water level, the control device controls the water inlet pipe to stop filling with water, and controls the washing equipment to enter the soaking process.

[0068] The soaking process includes a first soaking process and a second soaking process.

[0069] In the first soaking process, the control device controls the inner drum to rotate at the soaking set start / stop timing for the first soaking time or rotate until the heating device heats to the set temperature, and then enters the second soaking process.

[0070] In some embodiments, there is no heating function or the heating function is not used, and the rotation of the inner drum is controlled according to the first soaking time.

[0071] In some embodiments, a heating function is used to control the washing device to heat to a soaking temperature, and the washing tub is controlled to rotate according to a soaking set start / stop timing (s / s).

[0072] Whether to use the heating function can be determined according to whether the heating function is available or according to user selection.

[0073] During the second soaking process, the control device controls the inner drum to rotate a set angle according to the interval time.

[0074] The interval time and the setting angle can be preset values.

[0075] Of course, in order to ensure that the foam overflows during the self-cleaning process, the foam height is monitored during the second soaking process, the interval time is determined according to the foam height, and the washing tub rotates at a set angle every interval time. The second soaking process continues to soak for the second soaking time.

[0076] The foam height is detected by the foam monitoring module. The interval time is the interval time between two rotations of the washing drum.

[0077] In some embodiments, the rotation setting angle is 30°-90°.

[0078] Among them, the interval time is positively correlated with the foam height. That is, the higher the foam height, the longer the interval time, and the lower the foam height, the shorter the interval time.

[0079] The more foam there is, the better the soaking effect will be. However, excessive rotation should be avoided to avoid the risk of overflow due to increased foam. Some of the foam can be eliminated by extending the interval time.

[0080] The length of the interval time can reflect the frequency of soaking and rotation. The more frequent the soaking and rotation, the greater the probability that the stains on the washing drum will fall off easily.

[0081] The soaking stage of the self-cleaning control method of the washing equipment is divided into two soaking stages. In the first soaking stage, soaking is carried out according to a certain start / stop sequence. At this time, a large amount of foam is easily generated. In order to avoid foam overflow, the foam height is monitored in the second soaking process, and the rotation interval time is dynamically determined according to the foam height to improve the soaking effect while avoiding foam problems, which is beneficial to the subsequent washing and rinsing and improves the self-cleaning effect.

[0082] In the second soaking process, in order to prevent the foam from overflowing, when the foam height exceeds the set height upper limit, the washing drum is controlled to stop rotating. When the foam height is lower than the set height upper limit, the rotation of the washing drum is resumed.

[0083] In order to improve the soaking effect, when the foam height is lower than the set height lower limit, the interval time for the washing drum to rotate the set angle is the set interval time.

[0084] Among them, the interval time is set shorter than other interval times to increase the rotation frequency and improve the soaking effect. At the same time, the rotation process can promote the removal of stains.

[0085] A controlled soaking phase in washing machines improves the self-cleaning effect and prevents foam overflow.

[0086] After soaking, it enters the self-cleaning washing stage.

[0087] The control device is used to control the rotation of the inner drum, control the pipeline switching device to switch to the second conduction state, and control the drum detergent dispensing device to dispense drum detergent when the washing equipment enters the self-cleaning washing stage and controls the water inlet pipe to flow into the washing water level.

[0088] During the washing water inlet stage, as the inner drum rotates, the front flushing component first sprays drum detergent into the washing drum in the direction of rotation of the inner drum to clean the washing drum, and the rear flushing component sprays water onto the washing drum with detergent to achieve the washing effect of the detergent and water flushing together, cleaning first and then flushing, to achieve the effect of continuously dissolving stains.

[0089] Specifically, the control device is used to control the inner drum to rotate clockwise (facing the drum mouth) when the washing device enters the self-cleaning washing stage and controls the water inlet pipeline to flow to the washing water level, and controls the pipeline switching device to make the front flushing component-the second flushing component 112 in the inner drum rotation direction connected with the detergent water inlet pipeline 41, and the rear flushing component-the first flushing component 111 is connected with the second water inlet pipeline 42, and controls the drum detergent delivery device to deliver the drum detergent, so that the drum detergent delivered by the second flushing component 112 is first pressurized to flush and clean the washing drum, and then the first flushing component 111 delivers clean water, and the stains are pressurized to be flushed to make them quickly detach and melt; control the inner drum When the drum rotates counterclockwise, the control pipeline switching device makes the front flushing component - the first flushing component 111 in the rotation direction of the inner drum connected to the detergent water inlet pipeline 41, and the rear flushing component - the second flushing component 112 is connected to the second water inlet pipeline 42, and the control drum detergent dispensing device dispenses the drum detergent. Therefore, the drum detergent dispensed by the first flushing component 111 is pressurized to flush and clean the washing drum, and then the second flushing component 112 dispenses clean water to pressurize and flush the stains to quickly separate and dissolve them; therefore, during the rotation of the inner drum, the drum detergent is always sprayed onto the washing drum first, and then the clean water is sprayed onto the washing drum, so as to clean first and then flush, and continuously dissolve the stains.

[0090] After the water inlet pipe fills up to the washing water level, the control device controls the water inlet pipe to stop filling, the drum detergent delivery device stops delivering the drum detergent, and the washing device is controlled to enter the washing process.

[0091] The washing process includes a first washing process and a second washing process.

[0092] In the first washing process, the control device controls the inner drum to rotate for the first washing time at the washing set start / stop timing.

[0093] In the second washing process, the control device controls the inner drum and the water inlet pipeline synchronously to run for a second set time with a set start / stop timing, ends the washing process, and drains the water.

[0094] During the second washing process, when water enters the water inlet pipe, the tub detergent dispensing device is controlled to dispense tub detergent.

[0095] A second washing process is added to further improve the washing effect by utilizing the flushing component for flushing and washing again based on the first washing process.

[0096] The control device is used to control the rotation of the inner drum and control the drum detergent dispensing device not to dispense drum detergent when the washing equipment enters the self-cleaning rinsing stage and controls the water inlet pipe to flow into the rinsing water level.

[0097] During the rinsing water inlet stage, all flushing components are rinsed with clean water to improve the rinsing effect.

[0098] During the rinsing stage, double pressure is used to rinse the stains, and no detergent is added. Specifically, no matter whether the washing machine rotates clockwise or counterclockwise, the flushing pipeline is no longer switched. At this time, all flushing components are filled with clean water to completely remove the stains and eliminate the drum detergent at the same time.

[0099] After the water inlet pipe fills up to the rinsing water level, the control device controls the water inlet pipe to stop filling, and controls the inner drum to rotate at the rinsing set start / stop timing to set the rinsing time.

[0100] Drain water after rinsing.

[0101] Among them, the number of rinse times can be set or preset in advance.

[0102] Of course, in order to ensure a clean rinse during the rinsing stage, the number of rinses can be automatically determined based on the foam during the rinsing process.

[0103] During the rinsing process, the foam height is monitored and the number of rinses is determined based on the foam height.

[0104] When the foam height exceeds the set height, an additional rinse is performed, otherwise, the rinsing process ends after the current rinse is completed.

[0105] The rinsing control method of the washing equipment can ensure clean rinsing.

[0106] Therefore, by adjusting the flushing order of water and detergent during the soaking process and the washing process, it is more in line with the washing rules, greatly improving the self-cleaning cleaning effect, while shortening the self-cleaning time and reducing water consumption.

[0107] Of course, in any water inlet process, the pipeline switching device can be used to switch the conduction state between the flushing component and the water inlet pipeline according to needs or settings, all of which are within the protection scope of the present invention.

[0108] When the washing equipment controls the water inlet pipe to flow water to the soaking water level / washing water level / rinsing water level, the inner drum rotates in the forward direction, the reverse direction, or the forward and reverse bidirectional alternating rotation.

[0109] During the process of water inlet pipe to the soaking water level / washing water level, when the inner drum switches the rotation direction, the control device controls the pipeline switching device to switch the flushing component connected to the detergent water inlet pipeline. The switching principle is that the front flushing component sprays clean water and the rear flushing component sprays the drum detergent during the soaking water inlet stage, and the front flushing component sprays the drum detergent and the rear flushing component sprays clean water during the washing water inlet stage.

[0110] The washing device includes a water inlet valve that controls a water inlet pipe. During the process of water inletting into the water inlet pipe, the control device controls the water inlet valve to always be open to achieve continuous water inlet. Alternatively, the control device controls the water inlet valve to open when the inner drum rotates and to close when the inner drum stops rotating, so as to achieve synchronization of water inlet and inner drum movement.

[0111] The water inlet valve can be a separate solenoid valve or electric valve, or it can be integrated in the pipeline switching device 5. The slider 52 has a third sliding position. In this position, the flushing component 1 and the water inlet pipeline 4 are cut off, and the washing device stops taking in water.

[0112] Since there are many types of existing drum cleaners, the types of drum cleaners are divided according to the dissolution rate, generally including three types: block (granular), powder and liquid. Since different types of drum cleaners have different water volumes and cleaning parameters required at different stages, the control device is used to obtain the type of drum cleaner and determine the soaking water level, washing water level and self-cleaning parameters according to the type of drum cleaner. The self-cleaning parameters include soaking parameters and washing parameters.

[0113] The soaking water level refers to the water level during the soaking stage.

[0114] Soaking parameters refer to the relevant parameters of washing equipment control during the soaking stage.

[0115] In some embodiments, the soak parameters include a soak start / stop sequence.

[0116] In some embodiments, the soaking parameters include a soaking start / stop sequence and a soaking temperature.

[0117] The first soaking time refers to the soaking time in the first soaking stage.

[0118] The second soaking time refers to the soaking time of the second soaking process.

[0119] Among them, the soaking water level is negatively correlated with the dissolution rate, the first soaking time is negatively correlated with the dissolution rate, the second soaking time is negatively correlated with the dissolution rate, the soaking start / stop timing is negatively correlated with the dissolution rate, and the soaking temperature is negatively correlated with the dissolution rate.

[0120] In some embodiments, the corresponding values ​​or value ranges of the drum detergent type and the soaking water level, the first soaking time, the second soaking time, the start / stop timing, and the soaking temperature are determined through preliminary experiments.

[0121] For example: Drum Cleaner Type Immersion water level (cm) Soaking temperature T(℃) First soaking time (min) First soaking sequence start / stop (s / s) Second soaking time (h) Block H1 T1 t11 t1z / t1t t21 Powder H2 T2 t12 t2z / t2t t22 liquid H3 T3 t13 t3z / t3t t23 Among them, H1>H2>H3.

[0122] T1>T2>T3.

[0123] t11>t12>t13.

[0124] t1z>t2z>t3z; t1t>t2t>t3t.

[0125] t21>t22>t23.

[0126] The rotation speed of the soaking drum in the soaking stage is a first set rotation speed, for example, the first set rotation speed is any value of 40-90 rpm.

[0127] During the soaking stage, different soaking start / stop sequences, soaking temperatures and soaking times are formulated according to different types of drum cleaners, which are conducive to the rapid melting, dispersion and action of the drum cleaners. The low-frequency, small-angle rotation and reversing pressurized flushing method can achieve full infiltration of the drum wall under low water level conditions, while increasing the adhesion time of the cleaning agent on the outer surface of the inner drum, thereby fully realizing the soaking effect.

[0128] The wash water level refers to the water level during the wash phase.

[0129] Washing parameters include relevant parameters for washing equipment control during the washing phase.

[0130] In some embodiments, the washing parameters include a second washing process start / stop sequence.

[0131] In some embodiments, the wash parameters include wash temperature.

[0132] In some embodiments, the washing parameter includes a washing drum rotation speed, and the washing drum rotation speed in the washing stage is a second set rotation speed, for example, the second set rotation speed is any value of 40-60 rpm.

[0133] In some embodiments, the wash parameters include wash start / stop timing of the wash phases.

[0134] The values ​​or value ranges corresponding to the drum detergent type, the wash water level, the start / stop timing of the second wash stage, and the wash temperature are determined through preliminary experiments.

[0135] For example: Drum Cleaner Type Washing water level (cm) Washing temperature T(℃) Second washing process start / stop sequence (s / s) Block H1 T1 t1z / t1t Powder H2 T2 t2z / t2t liquid H3 T3 t3z / t3t Among them, H1>H2>H3.

[0136] T1>T2>T3.

[0137] t1z>t2z>t3z; t1t>t2t>t3t.

[0138] Based on the selected drum cleaning agent type, a strong wash, high water level and high speed washing method is adopted, and a reversing pressurized flushing is simultaneously adopted to accelerate the removal of stains, realize cleaning first and then flushing, and realize strong cleaning of stains in the drum.

[0139] The rinse water level refers to the water level during the rinsing phase.

[0140] The rinse parameters include the rinse drum speed, rinse start / stop timing (s / s) and rinse time as preset values.

[0141] According to the established rinse sequence and pressurized flushing sequence, use high water level and pressurized flushing to continuously flush away stains.

[0142] During the soaking water inlet stage of the washing equipment, as the inner drum rotates, the front flushing component first sprays a small amount of water to the washing drum in the direction of the inner drum rotation to wet the washing drum, and the rear flushing component sprays the drum detergent to the washing drum, so that the washing drum is attached with a high concentration of drum detergent, which greatly improves the cleaning effect of the drum detergent; during the washing water inlet stage, as the inner drum rotates, the front flushing component first sprays the drum detergent to the washing drum in the direction of the inner drum rotation, and the rear flushing component sprays water to the washing drum with detergent, so as to achieve the washing effect of the detergent and water flushing together, first cleaning and then flushing, and achieving the effect of continuously dissolving stains; during the rinsing water inlet stage, the dirt has been softened and dissolved, and all flushing components are flushed with clean water to improve the rinsing effect. Therefore, the washing equipment greatly improves the cleaning effect of self-cleaning, while shortening the self-cleaning time and reducing water consumption. Based on the above-mentioned washing equipment, this embodiment also proposes a self-cleaning control method: in the process of controlling the water inlet of the water inlet pipe, controlling the rotation of the inner drum, and controlling the action of the pipe switching device to make the water inlet pipe and the flushing component in the first conduction state or the second conduction state, and by changing the order of adding water and detergent, the self-cleaning cleaning effect is improved.

[0143] In order to make the delivery of water and detergent more reasonable, in some embodiments, the self-cleaning control method is: Entering the self-cleaning soaking stage, during the process of controlling the water inlet pipe to flow to the soaking water level, the inner drum is controlled to rotate, and the pipe switching device is controlled to switch to the first conduction state, that is, the front flushing component is connected with the ordinary water inlet pipe and the rear flushing component is connected with the detergent water inlet pipe in the direction of rotation of the inner drum, and the drum detergent delivery device is controlled to deliver the drum detergent; after the water flows to the soaking water level, the water supply is stopped and soaking is carried out.

[0144] The soaking process includes a first soaking process and a second soaking process.

[0145] In the first soaking process, the control device controls the inner drum to rotate at the soaking set start / stop timing for the first soaking time or rotate until the heating device heats to the set temperature, and then enters the second soaking process.

[0146] In some embodiments, there is no heating function or the heating function is not used, and the rotation of the inner drum is controlled according to the first soaking time.

[0147] In some embodiments, a heating function is used to control the washing device to heat to a soaking temperature, and the washing tub is controlled to rotate according to a soaking set start / stop timing (s / s).

[0148] Whether to use the heating function can be determined according to whether the heating function is available or according to user selection.

[0149] During the second soaking process, the control device controls the inner drum to rotate a set angle according to the interval time.

[0150] The interval time and the setting angle can be preset values.

[0151] Of course, in order to ensure that the foam overflows during the self-cleaning process, the foam height is monitored during the second soaking process, the interval time is determined according to the foam height, and the washing tub rotates at a set angle every interval time. The second soaking process continues to soak for the second soaking time.

[0152] The foam height is detected by the foam monitoring module. The interval time is the interval time between two rotations of the washing drum.

[0153] In some embodiments, the rotation setting angle is 30°-90°.

[0154] Among them, the interval time is positively correlated with the foam height. That is, the higher the foam height, the longer the interval time, and the lower the foam height, the shorter the interval time.

[0155] The more foam there is, the better the soaking effect will be. However, excessive rotation should be avoided to avoid the risk of overflow due to increased foam. Some of the foam can be eliminated by extending the interval time.

[0156] The length of the interval time can reflect the frequency of soaking and rotation. The more frequent the soaking and rotation, the greater the probability that the stains on the washing drum will fall off easily.

[0157] The immersion stage of the self-cleaning control method of the washing equipment is divided into two immersion stages. In the first immersion stage, the immersion is carried out according to a certain start / stop sequence. At this time, a large amount of foam is easily generated. In order to avoid foam overflow, the foam height is monitored in the second immersion process, and the rotation interval time is dynamically determined according to the foam height to improve the immersion effect while avoiding foam problems, which is beneficial to the subsequent washing and rinsing and improves the self-cleaning effect.

[0158] In the second soaking process, in order to prevent the foam from overflowing, when the foam height exceeds the set height upper limit, the washing drum is controlled to stop rotating. When the foam height is lower than the set height upper limit, the rotation of the washing drum is resumed.

[0159] In order to improve the soaking effect, when the foam height is lower than the set height lower limit, the interval time for the washing drum to rotate the set angle is the set interval time.

[0160] Among them, the interval time is set shorter than other interval times to increase the rotation frequency and improve the soaking effect. At the same time, the rotation process can promote the removal of stains.

[0161] The immersion control method of washing equipment can improve the self-cleaning effect and prevent foam overflow.

[0162] Entering the self-cleaning washing stage, during the process of controlling the water inlet pipe to flow to the washing water level, the inner drum is controlled to rotate, and the pipe switching device is controlled to switch to the second conduction state, that is, the front flushing component is connected with the detergent water inlet pipe and the rear flushing component is connected with the ordinary water inlet pipe in the rotation direction of the inner drum, and the drum detergent delivery device is controlled to deliver the drum detergent; after the water flows to the washing water level, the water supply is stopped, washing is carried out, and the water is drained after the washing is completed.

[0163] After the water inlet pipe fills up to the washing water level, the control device controls the water inlet pipe to stop filling, the drum detergent delivery device stops delivering the drum detergent, and the washing device is controlled to enter the washing process.

[0164] The washing process includes a first washing process and a second washing process.

[0165] In the first washing process, the control device controls the inner drum to rotate for the first washing time at the washing set start / stop timing.

[0166] In the second washing process, the control device controls the inner drum and the water inlet pipeline synchronously to run for a second set time with a set start / stop timing, ends the washing process, and drains the water.

[0167] During the second washing process, when water enters the water inlet pipe, the tub detergent dispensing device is controlled to dispense tub detergent.

[0168] By adding a second washing process to use the flushing component again for flushing and washing based on the first washing process, the washing effect can be further improved.

[0169] Entering the self-cleaning rinsing stage, the water inlet pipe is controlled to flow to the rinsing water level, the inner drum is controlled to rotate, and the drum detergent delivery device is controlled not to deliver the drum detergent; after the water flows to the rinsing water level, the water supply is stopped and rinsing is performed.

[0170] During the rinsing water inlet stage, all flushing components are rinsed with clean water to improve the rinsing effect. During this stage, the pipeline switching device does not need to be operated and can be in any channel connected water inlet state.

[0171] After the water inlet pipe fills up to the rinsing water level, the control device controls the water inlet pipe to stop filling, and controls the inner drum to rotate at the rinsing set start / stop timing to set the rinsing time.

[0172] Drain water after rinsing.

[0173] Among them, the number of rinse times can be set or preset in advance.

[0174] Of course, in order to ensure a clean rinse during the rinsing stage, the number of rinses can be automatically determined based on the foam during the rinsing process.

[0175] During the rinsing process, the foam height is monitored and the number of rinses is determined based on the foam height.

[0176] When the foam height exceeds the set height, an additional rinse is performed, otherwise, the rinsing process ends after the current rinse is completed.

[0177] The rinsing control method of the washing equipment can ensure clean rinsing.

[0178] like Figure 5 As shown, the control method of this embodiment includes the following steps: S1. Start.

[0179] S2. Obtain the type of drum detergent, and determine relevant water level and self-cleaning parameters according to the type of drum detergent.

[0180] S3, when the water is fed to the soaking water level, the inner drum is controlled to rotate, the pipeline switching device is controlled to make the water inlet pipeline and the flushing component in the first conducting state, and the drum detergent delivery device is controlled to deliver the drum detergent. When the water is fed to the soaking water level, the water feeding is stopped.

[0181] The inner drum can always keep rotating in one direction, or keep rotating in one direction according to a certain start / stop sequence, or rotate in a forward and reverse direction alternately according to a certain start / stop sequence. In the case where the inner drum rotates in a forward and reverse direction alternately, the pipeline switching device needs to be actuated during the process of switching the rotation direction of the inner drum, so as to perform flushing according to the principle of flushing with clean water first and then flushing with drum detergent in the immersion water stage.

[0182] S4, first soaking process: control the inner drum to rotate at the soaking set start / stop sequence for the first soaking time or rotate until the heating device heats to the set temperature.

[0183] S5, second soaking process: control the inner drum to rotate the set angle according to the interval time. When the soaking time reaches the second soaking time, the soaking ends.

[0184] S6. When the water reaches the washing water level, the inner drum is controlled to rotate, the pipeline switching device is controlled to make the water inlet pipeline and the flushing component in the second conducting state, and the drum detergent delivery device is controlled to deliver the drum detergent. When the water reaches the washing water level, the water delivery is stopped.

[0185] The inner drum can always keep rotating in one direction, or keep rotating in one direction according to a certain start / stop sequence, or rotate forward and reverse alternately according to a certain start / stop sequence. In the case where the inner drum rotates forward and reverse alternately, the pipeline switching device needs to be actuated during the process of switching the rotation direction of the inner drum, so as to perform the washing according to the principle of first washing the drum with detergent and then washing with water in the washing water inlet stage.

[0186] S7, during the first washing process, the inner drum is controlled to rotate for the first washing time according to the washing set start / stop timing.

[0187] In washing equipment with heating function, heating is performed to the washing setting temperature and maintained.

[0188] S8. During the second washing process, the inner drum and the water inlet pipeline are controlled to run synchronously for a second set time with a set start / stop timing, and the washing process is ended and the water is drained.

[0189] S9, when the water is fed to the rinsing water level, the inner drum is controlled to rotate, and the drum detergent feeding device is controlled not to feed the drum detergent. When the water is fed to the rinsing water level, the water feeding is stopped.

[0190] S10, control the inner drum to run the rinsing time according to the rinsing drum speed and rinsing sequence start / stop sequence (s / s), end rinsing, and drain.

[0191] During the soaking water inlet stage of the washing equipment, as the inner drum rotates, the front flushing component first sprays a small amount of water to the washing drum in the direction of the inner drum rotation to wet the washing drum, and the rear flushing component sprays the drum detergent to the washing drum, so that the washing drum is attached with a high concentration of drum detergent, which greatly improves the cleaning effect of the drum detergent; during the washing water inlet stage, as the inner drum rotates, the front flushing component first sprays the drum detergent to the washing drum in the direction of the inner drum rotation, and the rear flushing component sprays water to the washing drum with detergent, so as to achieve the washing effect of the detergent and water flushing together, first cleaning and then flushing, and achieving the effect of continuously dissolving stains; during the rinsing water inlet stage, the dirt has been softened and dissolved, and all flushing components are flushed with clean water to improve the rinsing effect. Therefore, the washing equipment greatly improves the cleaning effect of self-cleaning, while shortening the self-cleaning time and reducing water consumption.

[0192] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for a person skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to replace some of the technical features therein by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions claimed to be protected by the present invention.
