Description

Technical Field

[0001] This invention belongs to the field of mechanical equipment technology, specifically, it relates to a water inlet control method for a washing device and the washing device itself. Background Technology

[0002] "Washing equipment" refers to a general term for a class of household appliances that can perform washing, dehydration, and drying processes, such as washing machines and washer-dryer combos.

[0003] In existing technologies, the water intake of washing machines is mostly determined by weighing. Specifically, the forward and reverse rotation of the washing machine motor is controlled, and the weight of the clothes to be processed is determined based on the back electromotive force pulse value data of the motor. Then, the preset water intake level is determined, and the water level is detected in real time by a water level sensor. When the detected water intake level reaches the preset water intake level, the water intake is stopped.

[0004] In this water intake method, because the densities of the clothes to be treated often vary, even for clothes of the same weight, the volume difference is significant, resulting in different heights within the tub. Therefore, determining the water level solely based on the weight of the clothes will lead to inaccuracies. Specifically, for clothes of the same weight, if the density of the clothes is too high, their height within the tub will be too low, and the water level will be much higher than the clothes, resulting in wasted water. Conversely, if the density of the clothes is too low, their height within the tub will be too high, and the water level will be lower than the clothes, failing to fully submerge them and resulting in poor washing performance.

[0005] Furthermore, some washing machines determine the water level solely based on the height of the clothes inside the machine. Once the water level is detected to be higher than the height of the clothes, the water intake is completed. In this method, if the clothes float, the detected height of the clothes becomes inaccurate, and consequently, the amount of water controlled based on the height of the clothes will also be inaccurate.

[0006] In view of this, the present invention is hereby proposed. Summary of the Invention

[0007] The purpose of this invention is to provide a water inlet control method for a washing machine, so as to avoid the interference of floating clothes on the water inlet of the washing machine and to make the water inlet volume of the washing machine more accurate; another purpose of this invention is to provide a washing machine to achieve intelligent control of the water inlet volume of the washing machine, so as to make the water inlet volume of the washing machine more accurate.

[0008] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by the present invention is as follows:

[0009] A water inlet control method for a washing device, the washing device including a tub for holding clothes, the control method including: setting a preset water inlet level v0, determining whether the clothes in the tub are floating during the water inlet process, if so, controlling the water inlet to the preset water level v0, otherwise, controlling the water inlet volume according to the height of the clothes in the tub.

[0010] Furthermore, determining whether the clothes inside the bucket are floating includes: before water enters, obtaining the height h0 of the clothes inside the bucket; during water entry, obtaining the height h0' of the clothes inside the bucket; comparing the size of h0 and h0'; if h0' > h0, then the clothes are determined to be floating.

[0011] Furthermore, before water is introduced, the heights of the clothing at different locations inside the bucket are measured as h1, h2...h n h1, h2...h n The average value is taken as the obtained clothing height h0;

[0012] During the water intake process, the heights of the clothing at different positions inside the bucket are measured as h1', h2', ... h'. n ', h1', h2'...h n The average value of ' is used as the obtained clothing height h0';

[0013] Preferably, the rotation of the tank is controlled before and / or during water intake.

[0014] Furthermore, controlling the water intake based on the height of the clothes inside the bucket includes:

[0015] During the water intake process, the bucket is rotated to obtain the heights of the clothing at different positions inside the bucket, h1', h2', ... h'. n ', calculate h1', h2'...h n The deviation value Q between ' is preset to a deviation value Q0. The magnitudes of Q and Q0 are compared. If Q < Q0, the water intake is completed.

[0016] Preferably, the deviation value Q includes variance and standard deviation.

[0017] Furthermore, the water intake process includes several stages. After each stage is completed, the heights of the clothing at different positions inside the container are controlled and measured as h1', h2', ... h'. n '.

[0018] Furthermore, the water inflow rate for each water inflow stage is K*v0, where k < 1;

[0019] Preferably, 0.1 ≤ k ≤ 0.5;

[0020] Preferably, K is positively correlated with the height of the clothes in the bucket.

[0021] Furthermore, the preset water level v0 includes: before water is introduced, the height h of the clothes inside the bucket is obtained, the calculation model of the preset water level is v0 = f1(h) ± f2(h), and the obtained height h of the clothes is substituted into the calculation model to obtain the water level v0.

[0022] Furthermore, obtaining the height h of the clothing inside the bucket includes: obtaining the heights h1, h2, ... h of the clothing at different positions inside the bucket. n In the computational model

[0023] Furthermore, if it is determined that the clothes inside the bucket are floating, water is added in multiple stages. After each addition, the water level value v inside the bucket is obtained and compared with the preset water level v0. If v ≥ v0, the water addition is completed.

[0024] The present invention also provides a washing device, which is controlled by any of the control methods described in the above technical solutions.

[0025] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art.

[0026] During the water intake process of this invention, if it is determined that the clothes are floating, the washing equipment is controlled to directly intake water to the preset water level to avoid the floating clothes interfering with the judgment of the clothes height, which would lead to excessive water intake, waste of water resources, and safety hazards. If it is determined that the clothes are not floating, the water intake is controlled according to the height of the clothes, so that the water intake is more accurate. On the one hand, it ensures that the water intake can submerge the clothes and ensure a good washing effect, and on the other hand, it does not allow excessive water intake to avoid waste of water resources.

[0027] In this invention, the height h0 of the clothes inside the tub is obtained before water is introduced, which is equivalent to obtaining the actual height of the clothes inside the tub. During water introduction, the height h0' of the clothes inside the tub is obtained. If h0' > h0, it indicates that the height of the clothes inside the tub has increased during water introduction, thus indicating that the clothes are floating under the buoyancy of the washing water; otherwise, it indicates that the clothes are not floating. The control method of this invention can accurately determine the floating status of the clothes inside the tub, which is beneficial for accurately controlling the water intake of the washing equipment based on the determined floating status.

[0028] The washing equipment of the present invention is controlled by the control method of the present invention. The washing equipment of the present invention can achieve the purpose of intelligent water intake, so that the water intake process is not disturbed by the floating of clothes, and ensures accurate water intake. While improving the washing effect of clothes, it avoids the waste of water resources.

[0036] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0037] In the description of this invention, it should be noted that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0038] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0039] "Washing equipment" refers to a general term for a class of household appliances that can perform washing, dehydration, and drying processes, such as top-loading washing machines, front-loading washing machines, and washer-dryer combos.

[0040] The washing equipment includes a tub for holding clothes. The water inlet control methods for the washing equipment include:

[0041] The preset water level is v0. During the water intake process, it is determined whether the clothes in the bucket are floating. If so, the water intake is controlled to the preset water level v0. Otherwise, the water intake is controlled according to the height of the clothes in the bucket.

[0042] Specifically, such as Figure 1 As shown, the control steps of the washing equipment include:

[0043] S1, Begin;

[0044] S2, preset inlet water level v0;

[0045] S3. During the water intake process, determine whether the clothes inside the bucket are floating; if so, control the water intake to the preset water level v0; otherwise, control the water intake according to the height of the clothes inside the bucket.

[0046] S4. Determine if water intake is complete; if yes, control the water intake to end; otherwise, repeat steps S3 and S4.

[0047] In this invention, a dispensing port for dispensing clothing is provided at the top of the bucket, and a distance measuring sensor, such as a laser distance measuring sensor or an ultrasonic distance measuring sensor, is provided at the edge of the dispensing port.

[0048] Specifically, taking a laser rangefinder sensor as an example, the laser rangefinder sensor first emits a laser pulse from a laser diode aimed at the bottom of the barrel. After being reflected by the clothing, the laser light is scattered in all directions, and some of the scattered light returns to the sensor receiver. After being received by the optical system, it is imaged onto the avalanche photodiode.

[0049] An avalanche photodiode is an optical sensor with internal amplification, enabling it to detect extremely weak light signals. By recording and processing the time it takes for a light pulse to travel from emission to reception, the distance from the clothing to the inlet can be determined. The height of the clothing inside the container can then be calculated by subtracting this distance from the container's height.

[0050] In this invention, if it is determined that the clothes are floating during the water intake process, the washing equipment is controlled to directly intake water to the preset water level to avoid the floating clothes interfering with the judgment of the clothes height, which would lead to excessive water intake, waste of water resources and safety hazards.

[0051] Conversely, if it is determined that the clothes are not floating, the water intake is controlled according to the height of the clothes to make the water intake more accurate. This ensures that the water intake can submerge the clothes for better washing results, while also preventing excessive water intake to avoid wasting water resources.

[0052] As one embodiment of the present invention, determining whether the clothes inside the bucket are floating includes:

[0053] Before water is introduced, obtain the height h0 of the clothes inside the bucket;

[0054] During the water intake process, the height h0' of the clothes inside the bucket is obtained;

[0055] Compare the values ​​of h0 and h0'. If h0' > h0, the clothes are considered to float; otherwise, the clothes are considered not to float.

[0056] Specifically, such as Figure 2 As shown, the control steps of the washing equipment include:

[0057] S1, Begin;

[0058] S2, preset inlet water level v0;

[0059] S3. Before water enters the tank, obtain the height h0 of the clothes inside the tank;

[0060] S4. During the water intake process, obtain the height h0' of the clothes inside the bucket;

[0061] S5. Compare the size of h0 and h0'; if h0' > h0, it is determined that the clothes are floating, and the water intake is controlled to the preset water level v0; otherwise, it is determined that the clothes are not floating, and the water intake is controlled according to the height of the clothes in the bucket.

[0062] S6. Determine whether the water intake is complete; if yes, control the water intake to end; otherwise, repeat steps S4 to S6.

[0063] In this embodiment, the height h0 of the clothes inside the tub is obtained before water is introduced, which is equivalent to obtaining the actual height of the clothes inside the tub; the height h0' of the clothes inside the tub is obtained during the water introduction process. If h0' > h0, it indicates that the height of the clothes inside the tub has increased during the water introduction process, which indicates that the clothes have floated under the buoyancy of the washing water; otherwise, it indicates that the clothes have not floated.

[0064] The control method in this embodiment can accurately determine the floating status of clothes in the tub, which is beneficial for accurately controlling the water intake of the washing equipment based on the determined floating status.

[0065] As one implementation method of this embodiment, obtaining the height h0 of the clothing inside the bucket includes:

[0066] Before water is introduced, the heights of the clothing at different locations inside the container are measured as h1, h2...h n h1, h2...h n The average value is used as the obtained clothing height h0. For example: to obtain the clothing heights h1, h2, h3, h4, and h5 at 5 positions inside the barrel, h0 = (h1 + h2 + h3 + h4 + h5) / 5.

[0067] Specifically, before water is introduced, the height of the clothing (h1) is measured. Then, the bucket is rotated by a certain angle, and the height of the clothing (h2) is measured again. This process is repeated to obtain the heights of the clothing (h1, h2, ... h) at different rotation angles of the bucket. n This way, h1, h2...h n The average value is used as the obtained clothing height h0, which makes the measurement value of clothing height h0 in the bucket before water is introduced more accurate.

[0068] Similarly, during the water intake process, the heights of the clothing at different locations inside the bucket are obtained as h1', h2', ... h. n ', h1', h2'...h n The average value of ' is used as the obtained clothing height h0'.

[0069] Specifically, during the water intake process, the height of the clothing h1' is first measured. Then, the bucket is rotated by a certain angle, and the height of the clothing h2' is measured again. This process is repeated to obtain the heights of the clothing h1', h2', ... h at different rotation angles of the bucket. n ', thus h1', h2'...h n The average value of ' is used as the height of the clothes h0' during the water intake process, making the measurement value of the height of the clothes h0' inside the bucket more accurate during the water intake process.

[0070] In this embodiment, the drum is rotated during the water intake process, so that the clothes can fully contact the washing water and be fully soaked, which further ensures the accuracy of subsequent water intake.

[0071] As one embodiment of the present invention, controlling the water intake based on the height of the clothes in the tub includes:

[0072] During the water intake process, the bucket is rotated to obtain the heights of the clothing at different positions inside the bucket, h1', h2', ... h'. n ', calculate h1', h2'...h n The deviation value Q between ' is preset to a deviation value Q0. The magnitudes of Q and Q0 are compared. If Q < Q0, the water intake is completed.

[0073] Specifically, such as Figure 3 As shown, the control steps of the washing equipment include:

[0074] S1, Begin;

[0075] S2, preset inlet water level v0, preset deviation value Q0;

[0076] S3. During the water intake process, determine whether the clothes inside the bucket are floating; if so, proceed to step S4; otherwise, proceed to steps S5 to S8.

[0077] S4. Control the water intake to the water level v0; determine whether the water intake is complete; if yes, control the water intake to end; otherwise, control the repetition of steps S3 and S4.

[0078] S5. During the water intake process, control the rotation of the tank;

[0079] S6. Obtain the heights of the clothing at different positions inside the bucket: h1', h2', ... h n ';

[0080] S7. Calculate h1', h2'...h n The deviation value Q between ';

[0081] S8. Compare Q with the preset deviation value Q0; if Q < Q0, then control the water intake to end; otherwise, repeat steps S5 to S8.

[0082] The deviation value Q includes variance, standard deviation, etc.

[0083] In this embodiment, during the water intake process, if the deviation value Q is less than the preset deviation value Q0, it indicates that the deviation between the height values ​​of clothes at different positions in the tub is small. That is, the detected height value can actually represent the water level height value in the tub, which indicates that the washing water has completely submerged the clothes. At this time, the water intake is sufficient to meet the washing requirements of the clothes. The water intake is controlled to end to avoid excessive water intake and waste of water resources.

[0084] If the deviation value Q is greater than or equal to the preset deviation value Q0, it indicates that the height of the clothes at different positions in the tub is significantly different. The clothes protrude above the water surface and are in an undulating state, which means that the clothes are not completely submerged in the washing water. In other words, the water intake at this time is not enough to meet the washing requirements of the clothes. Continue to increase the water intake to ensure a better washing effect on the clothes.

[0085] As one implementation method of this embodiment, the water intake process includes several water intake stages. After each water intake stage is completed, the heights of the clothes at different positions inside the bucket, h1', h2', ... h', are controlled and acquired. n '.

[0086] In this embodiment, after a water inlet stage is completed, the heights of the clothing at different positions h1', h2'...h are obtained. n To avoid water turbulence during water intake, which could interfere with the measurement of clothing height.

[0087] In addition, after each water intake stage is completed, a deviation value Q is calculated based on the detected height of the clothes at different positions. The water intake can then be controlled based on the magnitude of the deviation value Q and the preset deviation value Q0. This control method enables the washing equipment to detect the accurate water intake at each water intake stage, so as to accurately control the water intake of subsequent water intake.

[0088] As one implementation of this embodiment, the water intake volume for each water intake stage is K*v0, where k < 1; preferably, 0.1 ≤ k ≤ 0.5.

[0089] In this embodiment, a fixed amount of water K*v0 is introduced at each water inlet stage. This allows the system to determine whether the water volume is sufficient to completely submerge the clothes based on the height of the clothes inside the tub after each K*v0 water inlet stage, thus ensuring accurate control of the water volume during the water inlet process.

[0090] In another implementation of this embodiment, the control coefficient K is positively correlated with the height of the clothes inside the tub. Preferably, the control coefficient K decreases as the water level increases during the water inlet process.

[0091] In this embodiment, the higher the height of the clothes inside the tub, the more water is needed to immerse the clothes. Therefore, the larger the control coefficient K, the more water is needed in each water intake stage, so as to ensure that the water intake efficiency of the washing equipment is high.

[0092] Furthermore, as the water level increases, the amount of water entering the tank increases. At this point, the control coefficient K decreases in order to accurately control the subsequent water intake.

[0093] As another embodiment of the present invention, the preset water level v0 includes: before water is introduced, the height h of the clothes inside the bucket is obtained, the calculation model of the preset water level v0 = f1(h) ± f2(h) is used, and the obtained height h of the clothes is substituted into the calculation model to obtain the water level v0.

[0094] Specifically, such as Figure 4 As shown, the control steps of the washing equipment include:

[0095] S1, Begin;

[0096] S2. Before water enters the tank, obtain the height h of the clothes inside the tank;

[0097] S3. The calculation model of the preset water inlet level is v0 = f1(h) ± f2(h). The obtained clothing height h is substituted into the calculation model to obtain the water inlet level v0.

[0098] S4. During the water intake process, determine whether the clothes inside the bucket are floating; if so, control the water intake to the preset water level v0; otherwise, control the water intake according to the height of the clothes inside the bucket.

[0099] S5. Determine if water intake is complete; if yes, control the water intake to end; otherwise, repeat steps S4 and S5.

[0100] In this embodiment, the calculation model v0 = f1(h) ± f2(h) is a function related to the height h of the clothes. That is, the preset water level v0 is calculated based on the height h of the clothes to ensure that the preset water level v0 meets the washing requirements of the clothes. The calculation model v0 = f1(h) ± f2(h) is an empirical model obtained through multiple tests before the washing equipment leaves the factory. The preset water level v0 calculated based on this model can meet the washing requirements without wasting water resources.

[0101] For example: in the calculation model v0=f1(h)±f2(h), f1(h)=h1+h2......+h n / n, Among them, the preset water level v0 can be v 0min With v 0max Fluctuations between

[0102]

[0103]

[0104] In another embodiment of the present invention, if it is determined that the clothes in the bucket are floating, water is controlled to be added in multiple times. After each water addition, the water level value v in the bucket is obtained, and the obtained water level value v is compared with the preset water level v0. If v ≥ v0, the water addition is controlled to be completed; if v < v0, the water addition is controlled to continue.

[0105] In this embodiment, if the clothes in the tub are floating, water is introduced in multiple stages so that the water flow can wash the floating clothes during each water introduction process. This allows the floating clothes to fully contact the water flow and, under the impact of the water flow, reduce their floating degree and fully contact the washing water, thereby improving the washing effect.

[0106] In this embodiment, the drum can be rotated during the water intake process. This rotation promotes contact between the clothes and the washing water, allowing the clothes to be thoroughly soaked and reducing their buoyancy. This prevents floating clothes from affecting the accuracy of water intake and further improves the accuracy of water intake.

[0107] As one embodiment of this invention, the control steps of the washing equipment include:

[0108] S1. Before water enters the container, obtain the height h0 of the clothes inside the container;

[0109] S2. During the water intake process, obtain the height h0' of the clothes inside the bucket;

[0110] S3. Compare the size of h0 and h0'. If h0' > h0, then determine that the clothes are floating and control the execution of step S4; otherwise, determine that the clothes are not floating and control the execution of step S5.

[0111] S4. Control the calculation difference △h = h0' - h0, preset the difference △h0, compare the difference △h with the preset difference △h0. If △h is greater than the preset difference △h0, control to increase the number of water inlets; otherwise, control to add water according to the preset number of water inlets.

[0112] The preset difference △h0 can be set according to the height h0 of the clothes in the bucket obtained before water enters. For example, the preset difference △h0 can be 1 / 6 of h0.

[0113] S5. Control the water intake according to the height of the clothes in the bucket.

[0114] In this embodiment, if the difference △h is greater than the preset difference △h0, it indicates that the clothes are floating. At this time, the number of water intakes is increased so that the floating clothes can be reduced under the impact of multiple water intakes, so as to ensure a better washing effect.

[0115] This invention also provides a washing device controlled by any of the control methods described above. The washing device of this invention, controlled by the control method of this invention, can achieve intelligent water intake, ensuring that the water intake process is not disturbed by floating clothes and guaranteeing the accuracy of water intake. This improves the washing effect on clothes while avoiding water waste.

[0116] In one embodiment of the present invention, the washing equipment has an inlet at the top of the tub for loading clothes into the tub, and a distance sensor, such as a laser distance sensor or an ultrasonic distance sensor, is installed at the edge of the inlet. The washing equipment also includes a controller, which is electrically or communicatively connected to the distance sensor, for receiving signals from the distance sensor and controlling the water intake program of the washing equipment according to the received signals.

[0117] In this embodiment, a distance sensor is set up to detect the height of the clothes inside the bucket during the water intake process, and then the height of the clothes is used to determine whether the clothes are floating, and the water intake is accurately controlled according to the height of the clothes.

[0118] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-described technical content to create equivalent embodiments without departing from the scope of the present invention. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the scope of the present invention.
