Technical Field

[0001] This application belongs to the technical field of washing equipment, and particularly relates to a pulsator washing machine, its control method, control device, and storage medium. Background Art

[0002] During the washing process of a washing machine, the generation of foam is a common phenomenon. Although the use of detergent can effectively remove stains, in the case of adding too much detergent or having fewer clothes, there will be too much foam, which affects the dehydration effect. Therefore, it is necessary to eliminate foam during the use of the washing machine. However, the existing defoaming methods of washing machines have poor defoaming effects. Summary of the Invention

[0015] In a second aspect, an embodiment of the present application further provides a control method for a pulsator washing machine, which is applied to the pulsator washing machine described in the above embodiments. The control method includes:

[0016] Obtain a water level frequency value;

[0017] When the water level frequency value is less than a preset threshold, execute a defoaming mode; wherein, the defoaming mode includes controlling the inner tub to rotate and execute the preset rotation mode for a first preset duration, so that the washing water between the inner tub and the outer tub rises and is guided to the inner tub through the diversion structure.

When it is detected that there are many bubbles, the inner tub is controlled to execute the preset rotation mode, so that the diversion structure guides the water flow circulation between the outer tub and the inner tub into the inner tub. The circulating sprayed water flow impacts the foam layer, and the foam structure is destroyed by mechanical force. The washing water passes through the anti-foaming box during the circulating flow process, and the defoaming liquid is released through the solid slow-release anti-foaming agent. The defoaming liquid enters the inner tub along with the water flow and is evenly distributed on the surface of the clothes and the foam through spraying, further reducing the number of bubbles. Combining the two methods of mechanical impact and chemical defoaming can more efficiently remove bubbles, avoid the influence of foam accumulation on the washing effect, and improve the defoaming effect of the washing machine.

[0050] With the improvement of people's living standards, users' requirements for washing machines have not only been satisfied with basic cleaning and convenience. The residue of detergent on clothes is also a particularly concerned aspect. During the washing process of a washing machine, the generation of foam is a common phenomenon. Although using detergent can effectively remove stains, when too much detergent is used or there are few clothes, there will be too much foam, which affects the dehydration effect. Excessive foam will not only prevent the clothes from being fully dehydrated, but may also cause the foam to overflow, increasing the difficulty of cleaning and maintenance. Excessive foam remaining on the clothes will affect the subsequent use experience of the clothes and may even cause problems such as skin allergies. The current defoaming methods include multiple water inlet rinsing, blowing, high-speed dehydration, etc., with low defoaming efficiency and water consumption, increasing the overall cost of the machine.

[0051] The embodiment of the present application provides a pulsator washing machine, its control method, control device and storage medium to solve the problem of poor defoaming effect of existing washing machines. The following will be described in conjunction with the attached Figures 1-8 for illustration.

[0052] Refer to Figure 1 and Figure 2 As shown, the pulsator washing machine provided by the embodiment of the present application includes an inner tub 100, an outer tub 200 and a defoaming box 300. The inner tub 100 has a preset rotation mode. The outer tub 200 is sleeved outside the inner tub 100. A diversion structure 220 is provided on the outer tub 200. One end of the diversion structure 220 is connected to the inner tub 100, and the other end is connected to the gap between the inner tub 100 and the outer tub 200. When the inner tub 100 executes the preset rotation mode, the water in the inner tub 100 is lifted into the gap and enters the diversion structure 220. The water is diverted by the diversion structure 220 and flows into the inner tub 100. The defoaming box 300 is arranged in the diversion structure 220, and a defoaming agent is accommodated in the defoaming box 300.

[0053] It should be noted that the preset rotation mode is the circulating spray mode or the waterfall mode of the pulsator washing machine, that is, it is used to lift the water cycle at the gap between the inner tub 100 and the outer tub 200 and divert it into the inner tub 100 through the diversion structure 220, which can be specifically achieved by increasing the rotation speed of the inner tub 100.

[0054] It can be understood that in this embodiment, there is a certain gap between the inner cylinder 100 and the outer cylinder 200, which provides necessary space for the rotation of the inner cylinder 100. At the same time, this gap is communicable with the internal space of the inner cylinder 100, that is, the water in the inner cylinder 100 can flow into the gap between the inner cylinder 100 and the outer cylinder 200. When the inner cylinder 100 rotates, it can drive the water in the gap to rotate together, and under the action of centrifugal force, the water rises to the cylinder cover 210 and is sprayed into the inner cylinder 100 from above the inner cylinder 100 under the water guiding action of the water guiding structure of the cylinder cover 210, so as to be sprayed on the surface of the clothes and the foam, break through the foam, and at the same time, the flow of the washing water will also drive the foam to flow, and the structure of the foam is damaged during the flowing process to achieve foam elimination.

[0055] The defoaming box 300 is installed at an appropriate position of the diversion structure 220 to ensure that it can effectively contact the washing water circulation path. During the flow of the circulating water, it contacts the defoaming agent in the defoaming box 300 and dissolves part of the defoaming agent to form a defoaming liquid. The defoaming liquid enters the inner cylinder 100 with the water flow. When the defoaming liquid is sprayed on the surface of the foam, it can reduce the surface tension of the foam and cause the foam to break, achieving defoaming.

[0056] By combining the two methods of mechanical impact and chemical defoaming, foam can be removed more efficiently, avoiding the influence of foam accumulation on the washing effect. The uniform distribution of the circulating water flow on the surface of the clothes improves the defoaming effect and efficiency. It can also avoid multiple rinses, reduce water and electricity consumption, and improve the energy-saving effect of the washing machine.

[0057] After defoaming, the dehydration process will be smoother, avoiding the situation of dehydration failure, and there is less detergent residue on the clothes, reducing the occurrence of problems such as the user not being able to wash clean, detergent residue, and not being able to dry.

[0058] Optionally, the types of defoaming agents can include but are not limited to silicone-based, polyether-based, fluorocarbon-based, etc., and can be selected according to actual needs. This embodiment does not make specific limitations on this.

[0059] In some alternative embodiments, the pulsator washing machine is also equipped with an ultrasonic defoaming device. When it detects that there is more foam, the ultrasonic defoaming device can be started to destroy the foam structure by using the high-frequency vibration of ultrasonic waves and quickly eliminate the foam.

[0060] In some alternative embodiments, the washing machine is also equipped with a steam generating device. When it detects that there is more foam, it uses steam cleaning technology to decompose and remove the foam through high-temperature steam.

[0061] In an alternative embodiment, combining Figure 1 and Figure 2As shown in the figure, a cylinder cover 210 is provided at the top of the outer cylinder 200, and a diversion structure 220 is provided on the cylinder cover 210. The diversion structure 220 includes a plurality of diversion ribs 221. The plurality of diversion ribs 221 are arranged at intervals along the circumferential direction of the cylinder cover 210, and a diversion groove 222 is formed between two adjacent diversion ribs 221. The defoaming box 300 is arranged in the diversion groove 222.

[0062] It can be understood that by arranging a plurality of diversion ribs 221 at intervals along the circumferential direction of the annular cylinder cover 210, the water flow led out by the diversion structure 220 can radially and comprehensively cover the axial region inside the washing tub, form a water curtain, and fully contact with the foam in the inner cylinder 100 to achieve defoaming, improving the defoaming effect.

[0063] When the washing water is guided down by the diversion ribs 221 on the cylinder cover 210, the water flow will pass through the defoaming box 300 arranged in the diversion groove 222, contact with the defoaming agent in the defoaming box 300 to form a defoaming liquid, and then enter the inside of the inner cylinder 100 to contact the clothes and foam. Due to the action of the defoaming agent, the foam is quickly dispersed or eliminated, thus avoiding the problem of foam accumulation.

[0064] In an optional embodiment, the water diversion groove extends from the edge of the annular cylinder cover 210 towards the center, and along the extension direction of the water diversion groove, the width of the water diversion groove gradually decreases, which is beneficial to accelerating the water flow speed and enhancing the spraying effect, so as to fully eliminate the foam.

[0065] In an optional embodiment, the number of the defoaming boxes 300 is multiple, and the multiple defoaming boxes 300 are arranged at intervals along the circumferential direction of the cylinder cover 210.

[0066] The arrangement of the multiple defoaming boxes 300 enables each diversion groove 222 to independently introduce the defoaming agent, ensuring that the water flow can be fully mixed with the defoaming agent at different positions around the cylinder cover 210, so as to form a defoaming liquid with multi-point and uniform distribution in the entire washing tub. This design can more comprehensively eliminate the foam and avoid the problem of insufficient local defoaming caused by a single defoaming area.

[0067] In an optional embodiment, the defoaming box 300 and the cylinder cover 210 are of an integral structure, which omits the step of separately assembling the defoaming box 300, simplifies the production process, and reduces the installation complexity. Moreover, the space can be more reasonably utilized, making the structure of the whole washing machine more compact.

[0068] In an optional embodiment, in combination Figure 1 、 Figure 3 and Figure 4 As shown in the figure, the defoaming box 300 penetrates through the cylinder cover 210, and an opening 310 is formed at one end of the defoaming box 300 facing away from the inner cylinder 100. The defoaming box 300 is also provided with a box cover 320, and the box cover 320 is rotatably arranged to open or close the opening 310.

[0069] In this embodiment, the opening 310 is provided at one end of the defoaming box 300 facing away from the inner cylinder 100, which facilitates the user to add or replace the defoaming agent in the defoaming box 300, simplifies the maintenance operation steps of the defoaming box 300, and improves the user experience. The lid 320 can effectively seal the opening 310 to prevent foreign objects from entering the interior of the defoaming box 300 and affecting the washing effect and defoaming effect.

[0070] In an alternative embodiment, in combination with Figure 1 、 Figure 3 and Figure 4 as shown, the defoaming box 300 is provided with a mounting groove 330, and the lid 320 is provided with a rotating shaft portion 321, and the rotating shaft portion 321 is sleeved in the mounting groove 330. The design of the rotating shaft portion 321 allows the lid 320 to rotate freely around the axis, facilitating the user to open and close the opening 310. Through the mechanical connection between the rotating shaft portion 321 and the mounting groove 330, the stability between the lid 320 and the defoaming box 300 is ensured, avoiding accidental loosening.

[0071] In an alternative embodiment, in combination with Figure 1 、 Figure 4 and Figure 5 as shown, the defoaming box 300 is provided with a card slot 340, and the lid 320 is provided with a clamping member 322. When the lid 320 covers the opening 310, the clamping member 322 is clamped in the card slot 340. The snap connection can provide a high fixing strength to ensure that the lid 320 will not accidentally open in the closed state. The user only needs to align the lid 320 and apply pressure to complete the fixation of the lid 320, and the operation is simple and fast.

[0072] In an alternative embodiment, in combination with Figure 1 and Figure 2 as shown, at least one of the bottom wall and the side surface of the defoaming box 300 is provided with a release hole 350, and the size of the release hole 350 is smaller than the size of the defoaming agent.

[0073] In this embodiment, the release holes 350 are opened on the bottom wall and the side surface of the defoaming box 300. The release holes 350 allow the washing water guided by the diversion structure 220 to flow into and out of the defoaming box 300, so as to contact the defoaming agent. The diameter or width of the release hole 350 is designed to be smaller than the size of the defoaming agent particles, so that the defoaming agent particles cannot leak out of the defoaming box 300 through the release hole 350, but the water flow can pass freely.

[0074] Due to the small size of the release holes 350, the defoamer can only be slowly dissolved and released into the water, thus controlling the release rate of the defoamer and ensuring a continuous defoaming effect. The design of the release holes 350 prevents the direct leakage of the defoamer. On the one hand, it reduces the waste of materials and extends the service life of the defoamer. On the other hand, it ensures that the defoamer does not directly enter the washing water, avoiding internal contamination of the washing equipment or other maintenance problems, and simplifies the cleaning and maintenance work of the equipment.

[0075] Optionally, the number of the release holes 350 is multiple, and the multiple release holes 350 are arranged at intervals along the circumferential direction of the defoaming box 300, increasing the chance of contact between water and the defoamer, which helps to improve the efficiency of dissolution and release of the defoamer, thereby improving the defoaming efficiency. And such a layout helps to ensure that the defoamer can be evenly released into the washing water, thus improving the sterilization uniformity of the entire washing process. Even if some of the release holes 350 are blocked by dirt, the other release holes 350 can still continue to work, reducing the overall performance degradation caused by the blockage of a single hole and improving the sterilization reliability.

[0076] In an alternative embodiment, the agitator washing machine further includes a counter and a display panel (not shown in the figure). The counter is used to calculate the slow-release times of the defoaming box 300, that is, the defoaming times. The display panel is connected to the counter to display the release times, and the display panel is configured to display a prompt message after the release times reach a preset number.

[0077] In this embodiment, the counter is an electronic device for recording and calculating the release times of the defoamer in the defoaming box 300. Each time the defoaming mode is executed in a washing cycle, when the defoamer is released, the counter will automatically increase the count by one time. Specifically, it can be determined by the diversion times of the diversion structure 220 or the number of times of executing a preset rotation mode. The display panel is connected to the counter and can display the release times of the defoaming box 300 in real time. The user can understand the usage situation of the defoamer through the display panel.

[0078] Furthermore, the display panel is configured with an intelligent reminder function. When the release times reach the preset number, that is, when the defoaming material is approaching or reaching its service life, the display panel will display a prompt message to notify the user that the defoamer needs to be replaced. Through the information provided by the display panel, the user can intuitively understand the usage status of the defoaming box 300 and can perform maintenance without professional knowledge. After the preset release times are reached, the prompt message on the display panel can help the user replace the defoamer in time, ensure that the defoaming effect of the washing machine is always in the best state, avoid the decline of the defoaming effect caused by the failure of the defoamer, and improve the user experience.

[0079] In a second aspect, the embodiments of the present application further provide a control method for an agitator washing machine, which is applied to the agitator washing machine in the above embodiment. Refer to Figure 6As shown, the control method includes:

[0080] S601: Obtain water level frequency value;

[0081] S602: When the water level frequency value is less than a preset threshold, a defoaming mode is executed; wherein the defoaming mode includes controlling the inner drum to rotate and executing a preset rotation mode for a first preset time.

[0082] For example, a pulsator washing machine has a built-in water level sensor for detecting the water level frequency value of the inner drum. The water level frequency value is used to reflect the water level height in the inner drum. The higher the water level height, the smaller the water level frequency value. The pulsator washing machine has been pre-set with a mapping relationship between the water level frequency value and the water level height when it leaves the factory.

[0083] Before using a pulsator washing machine to wash clothes, the user pre-sets the target water level height for washing. Based on the target water level height, the preset threshold of the water level frequency can be determined. When there is a lot of foam in the inner drum, the washing water mixes with the bubbles to form a water-gas mixture. The corresponding water level will be higher than the preset water level value, and the water level in the inner drum will rise, causing the water level frequency value detected by the washing machine to decrease. When the water level frequency value is lower than a certain level, it can be determined that there is a lot of foam generated in the washing machine, so it is necessary to execute the defoaming mode for defoaming.

[0084] When the water level frequency value is greater than or equal to the preset threshold, it means that the foam content is low. At this time, there is no need to execute the defoaming mode, and you can continue washing and dehydrating.

[0085] For example, assuming that the water level frequency value corresponding to the target water level height set by the user is N KHz, when the detected water level frequency value is less than (N-0.2) KHz, it is judged that there is a lot of foam. At this time, it is necessary to execute the defoaming mode for defoaming. The system controls the rotation of the inner drum, starts the combined defoaming mode of the defoaming agent and the waterfall spray system of the drum cover, starts the circulating spray system, and runs a cycle. The inner drum rotates at a high speed of 150-400rpm (for example, 150rpm, 200rpm, 300rpm or 400rpm), so that the water between the inner drum and the outer drum is thrown to the water flow guide ribs on the bottom wall of the drum cover. The washing water thrown out at high speed is guided by the streamlined flow channel, radially covers the axial area inside the inner drum, forms a water curtain, and sprays on the surface of the clothes. The flow of washing water will also cause the foam to flow, destroying the structure of the foam during the flow process, and the foam in the washing water will be reduced.

[0086] Optionally, in the preset rotation mode, the spraying process of the tub lid can be specifically as follows: Spraying starts at time t: the clutch tractor is turned on at t + 2s, the drain valve is not opened, the motor stops rotating at t + 10, and during the spraying process, the washing tub rotates at a high speed of 200 rpm, so that the water between the inner and outer tubs is thrown to the water flow guiding rib channel at the bottom of the outer tub lid. The high-speed thrown washing water is guided by the streamline of the channel and radiates to fully cover the axial area inside the washing tub, forming a water curtain and spraying on the surface of the clothes. The flow of the washing water will also drive the foam to flow, and the structure of the foam will be damaged during the flow process, so the foam in the washing water will decrease, and then the water level value will change. The waterfall ends at time T: the motor is powered off, the clutch is closed at T + 3s, and the motor starts at T + 8s.

[0087] In an alternative embodiment, after executing the defoaming mode, the method further includes:

[0088] Controlling the inner tub to stand still for a second preset duration;

[0089] Reacquiring the water level frequency value;

[0090] In the case where the water level frequency value is less than the preset threshold, continue to execute the defoaming mode; in the case where the water level frequency value is greater than or equal to the preset threshold, end the defoaming mode and continue washing.

[0091] Exemplarily, after executing a defoaming mode (including chemical defoaming and physical defoaming) once, the system controls the inner tub to stand still for a second preset duration (such as 2 - 5 minutes). During the standing stage, with the action of gravity and time, the foam further breaks, reduces or disappears.

[0092] After standing for the second preset duration, the system reacquires the current water level frequency value through the water level sensor. By detecting the change in the water level frequency, it is judged whether the foam has been eliminated to a predetermined degree. If the foam has not been completely eliminated, the defoaming mode needs to be continued. If it is detected that the foam has been effectively eliminated, the defoaming process can be ended, and the main washing or rinsing program can be continued.

[0093] It can be understood that the first preset duration and the second preset duration can also be other values, which can be specifically set according to actual needs, and the embodiment does not specifically limit their values.

[0094] In an alternative embodiment, before acquiring the water level frequency value, the method further includes: determining the washing stage of the pulsator washing machine; and performing the step of acquiring the water level frequency value when the washing stage meets the preset time period before the end of the washing program.

[0095] In this embodiment, the system checks whether the current washing stage is within a preset time period before the end of the washing program, ensuring that the step of obtaining the water level frequency value is only executed when the washing program is about to end, thereby improving the accuracy and relevance of foam detection and being able to more accurately reflect the foam content.

[0096] For example, the preset time period can be the last 90 seconds or the last 2 - 5 minutes or other time of the detailed program, which can be adjusted according to specific circumstances, and this embodiment does not make specific limitations in this regard.

[0097] By detecting and eliminating foam before the end of the washing stage, it is ensured that the foam has been effectively processed before entering the dehydration stage and the drainage stage, avoiding its impact on the normal operation of the dehydration process.
