Description

Technical Field

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

[0002] "Washing equipment" refers to all household appliances that can wash and spin-dry clothes, such as front-loading washing machines and top-loading washing machines.

[0003] Most washing machines currently have a spin-drying program for removing excess water from clothes. Specifically, the spin-drying program consists of stages such as intermittent spin-drying, constant-speed spin-drying, continuous spin-drying, and braking. The runtime of each stage of the spin-drying program is generally preset and cannot be adjusted adaptively according to the condition of the clothes in the washing machine drum.

[0004] In existing spin-drying programs, if the fabric of the clothes in the drum is highly absorbent, the clothes will have a high moisture content after washing, making spin-drying more difficult. In this case, continuing to spin-dry according to the preset program will result in poor dehydration. Conversely, if the fabric of the clothes in the drum is not highly absorbent, the clothes will have a low moisture content after washing, making spin-drying easier. In this case, continuing to spin-dry according to the preset program will waste the spin-drying time.

[0005] In view of this, the present invention is hereby proposed. Summary of the Invention

[0006] This invention provides a dehydration control method and washing equipment for washing equipment, so as to achieve precise and reasonable control of the dehydration time and dehydration speed of the washing equipment, and ensure a better dehydration effect.

[0007] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by the present invention is as follows:

[0008] A method for controlling the dehydration of a washing machine, the washing machine including a drum for holding clothes.

[0009] The material of the clothes inside the drum is obtained. During the dehydration process, the moisture content Q of the clothes inside the drum is obtained. The obtained moisture content is compared with the moisture content Q0 corresponding to the material. If Q > Q0, the dehydration speed of the drum is increased.

[0010] Preferably, the moisture content Q of the clothes inside the drum is calculated during the dehydration process, in the dehydration stage when the drum slows down.

[0011] Furthermore, controlling the increase in the dehydration speed of the barrel includes: controlling the increase in the dehydration speed of the barrel to be positively correlated with the moisture content Q0.

[0012] Furthermore, with a preset interval time t0 and a change value △Q0, during the dehydration process by increasing the dehydration speed, the change value △Q of the moisture content of the clothes within the interval time t0 is obtained. The obtained change value △Q is compared with the preset change value △Q0. If △Q≤△Q0, the dehydration can be controlled to end.

[0013] Furthermore, a preset number of times n0 is set and n0≥2, and several change values ​​△Q are continuously obtained. The cumulative number of times △Q≤△Q0 occurs is n. The cumulative number of times n is compared with the preset number of times n0. If n≥n0, the dehydration process ends.

[0014] Furthermore, the process of increasing the dehydration speed includes: controlling the drum speed to increase in a periodic manner of first increasing, then decreasing, and then increasing again, and obtaining the change value △Q of the moisture content of the clothes within the interval time t0 during the process of decreasing the speed.

[0015] Furthermore, the interval time t0 is controlled to be positively correlated with the moisture content Q0 corresponding to the obtained material.

[0016] Furthermore, the larger the moisture content Q0 corresponding to the clothing material, the shorter the duration of a single cycle in which the rotation speed of the control drum first increases, then decreases, and then increases again.

[0017] Furthermore, if the container contains clothing of various materials, the proportion of each material in the container is calculated, and the corresponding moisture content Q0 of each material is given by the formula Q0. 0n The sum of the products of its proportion.

[0018] Furthermore, obtaining the moisture content Q of the clothes inside the drum includes: detecting the weight Q1 of the clothes inside the drum before water is introduced, and detecting the weight Q2 of the clothes inside the drum during the dehydration process, wherein the moisture content Q = Q2 - Q1, or the moisture content Q = (Q2 - Q1) / Q1.

[0019] The present invention also provides a washing device, which is controlled by the dehydration control method described in any of the above technical solutions.

[0020] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art.

[0021] In this invention, the moisture content Q0 is related to the fabric material. When Q > Q0, it indicates that the moisture content of the fabric is still relatively high. In this case, the spin speed of the drum is increased to improve the spin-drying efficiency. Conversely, when Q ≤ Q0, it indicates that the moisture content of the fabric is relatively low. In this case, the spin-drying process can be stopped to avoid wasting time by continuing the spin-drying process. This invention uses the moisture content Q0 corresponding to the fabric material as a reference value to accurately and reasonably control the spin-drying time and spin speed during the spin-drying process, resulting in a better spin-drying effect.

[0022] In this invention, the higher the moisture content Q0 of the clothing material in the tub, the greater the difficulty of dehydrating the clothing. When the clothing is not completely dehydrated, the increase in the dehydration speed is directly controlled to increase the dehydration speed to a relatively large value, thereby improving the dehydration effect and ensuring that the clothing that is difficult to dehydrate can be dehydrated as quickly as possible in a shorter time.

[0023] The washing equipment of the present invention uses the dehydration control method of the present invention, which enables the washing equipment to reasonably control the dehydration time and dehydration speed according to the material of the clothes, thus ensuring a good dehydration effect on the clothes and avoiding waste of dehydration time.

The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

Therefore, they should not be construed as limitations on this invention.

[0033] 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.

[0034] "Washing equipment" refers to all household appliances capable of washing clothes, such as front-loading washing machines and top-loading washing machines. Washing equipment includes a drum for holding the clothes. It also has a spin-drying program to remove excess water from the clothes inside the drum.

[0035] like Figures 1 to 3 As shown, this invention discloses a control method for a washing machine. The dehydration control method includes: obtaining the material of the clothes inside the drum; during the dehydration process, obtaining the moisture content Q of the clothes inside the drum; comparing the obtained moisture content with the moisture content Q0 corresponding to the material; if Q > Q0, then controlling to increase the dehydration speed of the drum.

[0036] Specifically, as one embodiment of the present invention, such as Figure 1 As shown, the dehydration control steps of the washing equipment include:

[0037] S1, Begin;

[0038] S2, Obtain the material of the clothing inside the bucket;

[0039] S3. Obtain the moisture content Q0 corresponding to the material of the clothing inside the bucket;

[0040] S4. The dehydration process includes alternating acceleration and deceleration phases controlled by the drum. During the deceleration phase of the drum, the moisture content Q of the clothes inside the drum is obtained.

[0041] S5. Compare the obtained moisture content Q with the obtained moisture content Q0;

[0042] S6. Determine whether the obtained moisture content Q is greater than Q0; if yes, proceed to step S7; otherwise, proceed directly to step S8.

[0043] S7. Control the increase of the dehydration speed of the barrel; and return to step S4;

[0044] S8, Dehydration complete.

[0045] In this invention, the moisture content Q0 is related to the material of the clothing. When Q > Q0, it indicates that the moisture content of the clothing is still relatively high. At this time, the spin speed of the drum is increased to improve the spin-drying efficiency. Conversely, when Q ≤ Q0, it indicates that the moisture content of the clothing is relatively low. At this time, the spin-drying process can be stopped to avoid wasting spin-drying time by continuing the spin-drying process. This invention uses the moisture content Q0 corresponding to the material of the clothing as a reference value to accurately and reasonably control the spin-drying time and spin speed during the spin-drying process, resulting in a better spin-drying effect.

[0046] In one embodiment of this invention, in step S2, the washing equipment includes a lid for opening and closing the tub. A camera is installed inside the lid. Each time the user puts a garment into the tub, the camera takes a picture and sends it to the washing equipment's server. The server analyzes the image to determine the material of the garment. This embodiment can accurately determine the type of garment inside the tub.

[0047] In another implementation of this embodiment, in step S3, the database of the washing equipment pre-stores the moisture content Q0 corresponding to different clothing materials. Specifically, the moisture content Q0 is related to the water absorption performance of the clothing material; the stronger the water absorption performance of the clothing material, the higher its corresponding moisture content Q0; conversely, the lower the water absorption performance, the lower the moisture content Q0. Specifically, in step S3, obtaining the moisture content Q0 corresponding to the clothing material in the tub includes:

[0048] S31. Match the material information of the clothes inside the drum with the materials stored in the washing equipment database; S32. Select the moisture content Q0 corresponding to the successfully matched material.

[0049] In this embodiment, the stronger the water absorption of the clothing material, the higher the moisture content of the clothing after washing, and the more difficult it is to dehydrate. In this case, selecting a larger moisture content Q0 as the theoretical moisture content that the clothing can achieve after dehydration can better match the actual dehydration situation of the current clothing material, and avoid selecting a moisture content Q0 that is too low, which will not be able to reach the value in the actual dehydration process, thus wasting dehydration time.

[0050] As another implementation of this embodiment, the washing equipment can record the weight of clothes of different materials before and after washing and dehydration based on historical dehydration information, and calculate the corresponding moisture content Q0 based on the recorded information.

[0051] For example: Clothing A has a weight of 'a' before washing and a weight of 'b' after spin-drying. Then the moisture content of clothing A is Q0 = 'ba'. The moisture content Q0 of clothing A is stored in the database of the washing machine. The next time it is spin-dried, this value can be directly retrieved as the moisture content Q0 of clothing A.

[0052] In this embodiment, the moisture content Q0 corresponding to the user's clothing can be detected based on the actual moisture content of the clothing, making the moisture content Q0 more suitable for the current user's washing equipment and meeting the current user's actual needs.

[0053] In another embodiment of the present invention, controlling the increase of the dehydration speed of the barrel includes: controlling the increase of the dehydration speed of the barrel to be positively correlated with the moisture content Q0.

[0054] In this embodiment, the higher the moisture content Q0 of the clothing material in the bucket, the greater the difficulty of dehydrating the clothing. When the clothing is not completely dehydrated, the increase in the dehydration speed is directly controlled to increase the dehydration speed to a relatively large value, thereby improving the dehydration effect and ensuring that the clothing that is difficult to dehydrate can be dehydrated as quickly as possible in a shorter time.

[0055] As another embodiment of the present invention, the dehydration control method includes: a preset interval time t0 and a change value △Q0; during the dehydration process of increasing the dehydration speed, calculating the change value △Q of the moisture content of the clothes within the interval time t0; comparing the obtained change value △Q with the preset change value △Q0; if △Q≤△Q0, then the dehydration can be controlled to end.

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

[0057] S1, Begin;

[0058] S2, preset interval time t0, change value △Q0; for example: t0=10S;

[0059] S3, Obtain the material of the clothing inside the bucket;

[0060] S4. Obtain the moisture content Q0 corresponding to the material of the clothing inside the bucket;

[0061] S5. The dehydration process includes alternating acceleration and deceleration phases controlled by the drum. During the deceleration phase of the drum, the moisture content Q of the clothes inside the drum is obtained.

[0062] S6. Compare the obtained moisture content Q with the obtained moisture content Q0;

[0063] S7. Determine whether the obtained moisture content Q is greater than Q0; if yes, proceed to step S8; otherwise, proceed directly to step S11.

[0064] S8. Control the increase of the dehydration speed of the drum;

[0065] S9. Obtain the change value △Q of the moisture content of clothing within the interval time t0;

[0066] S10. Compare the obtained change value △Q with the preset change value △Q0;

[0067] S11. Determine whether the obtained change value △Q is less than or equal to the preset change value △Q0; if yes, proceed to step S12; otherwise, return to step S5.

[0068] S12, Dehydration complete.

[0069] In this embodiment, step S2 may also be set after step S4 and before step S5. In this embodiment, △Q0 < Q0; for example: △Q0 = 0.1 * Q0.

[0070] In this embodiment, if the obtained change value △Q is less than or equal to the preset change value △Q0, it indicates that the moisture content of the clothes has not changed significantly within the interval time t0. This further indicates that the current dehydration of the clothes has reached its limit and it is difficult to continue dehydrating. At this time, the dehydration is controlled to end to avoid blindly continuing to dehydrate, which would waste energy and also avoid unnecessary wear and tear on the clothes.

[0071] As one implementation method of this embodiment, a preset number of times n0 is set and n0≥2, several change values ​​△Q are continuously calculated, and the number of times △Q≤△Q0 occurs consecutively is accumulated n. The accumulated number of times n is compared with the preset number of times n0. If n≥n0, the dehydration is controlled to end.

[0072] Specifically, such as Figure 3 As shown, the control steps include:

[0073] S1, Begin;

[0074] S2, preset interval time t0, change value △Q0; for example: t0=10S;

[0075] S3, Obtain the material of the clothing inside the bucket;

[0076] S4. Obtain the moisture content Q0 corresponding to the material of the clothing inside the bucket;

[0077] S5. The dehydration process includes alternating acceleration and deceleration phases controlled by the drum. During the deceleration phase of the drum, the moisture content Q of the clothes inside the drum is obtained.

[0078] S6. Compare the obtained moisture content Q with the obtained moisture content Q0;

[0079] S7. Determine whether the obtained moisture content Q is greater than Q0; if yes, proceed to step S8; otherwise, proceed directly to step S14.

[0080] S8. Control the increase of the dehydration speed of the drum;

[0081] S9. Obtain the change value △Q of the moisture content of clothing within the interval time t0;

[0082] S10. Compare the obtained change value △Q with the preset change value △Q0;

[0083] S11. Determine whether the obtained change value △Q is less than or equal to the preset change value △Q0; if yes, proceed to step S12; otherwise, return to step S5.

[0084] S12, the cumulative number of times △Q≤△Q0 appears consecutively, n;

[0085] S13. Determine if the cumulative number of times n is greater than or equal to n0; if yes, proceed to step S14; otherwise, return to step S5.

[0086] S14, Dehydration complete.

[0087] In this embodiment, if the cumulative number of times n is greater than or equal to n0, it indicates that the moisture content of the clothes has not changed significantly after multiple consecutive detections. This further indicates that the current dehydration of the clothes has reached its limit and it is difficult to continue dehydrating. At this time, the dehydration is controlled to end, which not only ensures that the washing equipment has completely dehydrated the clothes, but also avoids blindly continuing to dehydrate, which would waste energy and cause unnecessary wear and tear on the clothes.

[0088] Conversely, if the cumulative number of times n is less than n0, it indicates that the phenomenon of no significant change in moisture content has occurred only by chance. This may be due to detection error. In this case, the washing equipment should be controlled to continue spinning to avoid the clothes not being dried due to misjudgment.

[0089] As another implementation method of this embodiment, such as Figure 4 As shown, the process of increasing the dehydration speed includes: controlling the speed of the drum to increase in a periodic manner of first increasing, then decreasing, and then increasing again.

[0090] For example: control the speed to first increase to 1000 r / min, then decrease to 500 r / min, then increase to 1500 r / min, then decrease to 1000 r / min, then increase to 2000 r / min, then decrease to 1500 r / min, then increase to 2500 r / min, then decrease to 2000 r / min, then increase to 3000 r / min.

[0091] In this embodiment, the change in moisture content of the clothing, ΔQ, is acquired during the decrease in rotational speed over an interval t0. During the deceleration phase, the water shaken off the clothing is discharged to the outside of the drum. At this time, the moisture content change value ΔQ is not affected by water not on the clothing, making the change value ΔQ more accurate and reliable. Therefore, the control of the dehydration process based on this change value ΔQ is also more accurate and reliable.

[0092] Furthermore, after the spin-drying speed is increased to the set value, a spin-drying time t is set. Within the spin-drying time t, the drum speed is reduced from the set value to 0 r / min, and the speed reduction value is calculated as: set value / spin-drying time t. The next time the spin-drying program is executed, the motor of the washing machine can be directly controlled to reduce the speed according to this speed reduction value.

[0093] For example: After increasing the spin speed to 3000 r / min, set the spin-drying time t, such as 30 seconds; control the washing machine to reduce its speed to 0 r / min within the spin-drying time t after the spin speed increases to 3000 r / min. The calculated reduction value is 3000 / 30 = 100. The next time the spin-drying program is executed, when the spin speed increases to 3000 r / min, directly control the washing machine's motor to reduce its speed according to the calculated reduction value. When the motor speed is detected to be 0, directly proceed to the next program to save the total running time of the washing machine.

[0094] In another embodiment of this invention, the interval time t0 is controlled to be positively correlated with the moisture content Q0 corresponding to the obtained material.

[0095] In this embodiment, the higher the moisture content Q0 of the material, the more difficult it is to dehydrate the garment, and the longer it takes for the water on the garment to be peeled off. At this time, the control interval t0 is longer to allow enough time for the water on the garment to be peeled off, and to avoid the interval t0 being too short, so that the water flow does not have enough time to be removed, resulting in the obtained change value ΔQ being too small, which in turn leads to a misjudgment that the dehydration is complete.

[0096] As another implementation of this embodiment, if the moisture content Q0 corresponding to the clothing material is larger, the duration of a single cycle in which the rotation speed of the control drum first increases, then decreases, and then increases again is shorter.

[0097] For example: In the first cycle T1: the rotation speed is first increased to 1000 r / min, then decreased to 500 r / min, and then increased to 1500 r / min; In the second cycle T2: the speed is decreased to 1000 r / min, then increased to 2000 r / min, and then decreased to 1500 r / min; In the third cycle T3: the speed is increased to 2500 r / min, then decreased to 2000 r / min, and then increased to 3000 r / min. The higher the moisture content Q0 corresponding to the clothing material, the shorter the control times T1, T2, and T3 should be.

[0098] In this embodiment, the higher the moisture content Q0 of the material, the more difficult it is to dehydrate the clothes. It is more difficult to remove water from the clothes. At this time, controlling the shortening of the single cycle time of the drum rotation speed first increases, then decreases and then increases again is equivalent to increasing the frequency of the drum rotation speed change, which is more conducive to shaking out the washing water from the clothes.

[0099] As one embodiment of the present invention, if the tub contains clothing of various materials, the proportion of each material in the tub is calculated, and the moisture content Q0 corresponding to each material is the moisture content Q0 corresponding to each material. 0n The sum of the products of its proportion.

[0100] Specifically, if the container contains clothing made of polyester, cotton-linen, and down; obtain the total weight G of the clothing, the weight G1 of the polyester clothing, the weight G2 of the cotton-linen clothing, and the weight G3 of the down clothing. Calculate the specific gravity G1 / G of the polyester clothing, the specific gravity G2 / G of the cotton-linen clothing, and the specific gravity G3 / G of the down clothing. The moisture content of the polyester clothing is Q. 01 The moisture content corresponding to cotton and linen materials is Q. 02 The moisture content corresponding to down material is Q. 03 The moisture content of the clothing material in the bucket, Q0 = Q 01 *G1 / G+Q 02 *G2 / G+Q 03 *G3 / G.

[0101] In this embodiment, for the case where the tub contains clothing of various materials, the moisture content Q0 is reasonably fitted and calculated so that the moisture content Q0 can be applied to the clothing in the tub. This ensures that all types of clothing in the tub can be thoroughly dehydrated, while avoiding excessive dehydration time and energy waste.

[0102] In another embodiment of the present invention, obtaining the moisture content Q of the clothes inside the drum includes: detecting the weight Q1 of the clothes inside the drum before water is introduced, and detecting the weight Q2 of the clothes inside the drum during the dehydration process, wherein the moisture content Q = Q2 - Q1, or the moisture content Q = (Q2 - Q1) / Q1.

[0103] In this embodiment, a sensor for detecting the weight of clothes inside the tub is installed inside the washing equipment. Detecting the weight Q1 of the clothes inside the tub before water enters includes: controlling the sensor to turn on before water enters to obtain the weight Q1 of the clothes inside the tub.

[0104] Alternatively, the washing equipment includes a motor for driving the drum rotation. Within a predetermined time (e.g., 5 minutes), the motor is accelerated to speed V1 (e.g., 1500 r / min), then decelerated to V2 (e.g., 1000 r / min). The time t required for the motor to decelerate from V1 to V2 is recorded, and the motor deceleration rate W1 = (V1 - V2) / t is calculated. The washing equipment's database pre-stores different motor deceleration rates W1 / t. n The weight Q of the clothes inside the corresponding bucket n Substitute the calculated deceleration rate W1 into the database and select the corresponding weight Q of the clothing. n This represents the weight of the clothes currently inside the bucket.

[0105] Specifically, detecting the weight Q1 of the clothes inside the tub before water intake includes: calculating the motor's deceleration rate W before water intake. 11 = (V1-V2) / t, calculate the deceleration rate W 11 Substitute the data into the database and select the corresponding weight Q of the clothing. n The weight of the clothing is Q1.

[0106] The weight Q2 of the clothes inside the drum during the spin-drying process includes: calculating the motor's deceleration rate W during the spin-drying process. 12 = (V1-V2) / t, calculate the deceleration rate W 12 Substitute the data into the database and select the corresponding weight Q of the clothing. n The weight of the clothing is Q2.

[0107] Alternatively, the washing machine's database may pre-store the weight Q of the clothes inside the drum corresponding to pulses at different motor speeds. n ;For example:

[0108]

[0109] Specifically, detecting the weight Q1 of the clothes inside the tank before water intake includes: acquiring the pulse when the motor speed is V1 before water intake, substituting the acquired pulse into the database, and selecting the corresponding weight Q of the clothes. n The weight of the clothing is Q1.

[0110] The process of detecting the weight Q2 of the clothes inside the drum during the spin-drying process includes: acquiring the pulse when the motor speed is V1 during the spin-drying process, substituting the acquired pulse into the database, and selecting the corresponding weight Q of the clothes. n The weight of the clothing is Q2.

[0111] More specifically, before water enters the drum, the weight Q1 of the clothes inside is obtained through a gravity sensor. After washing, the weight of the clothes inside the drum is obtained through a gravity sensor. The server of the washing equipment calls the optimal dehydration program for the current material of the clothes, namely the dehydration speed and dehydration time. The server sends the dehydration program to the control terminal of the washing equipment for setting.

[0112] Control the barrel to rotate for initial dehydration. When the initial dehydration is complete, compare the obtained moisture content with the corresponding moisture content Q0 of the material. If Q > Q0, perform N consecutive dehydration cycles until the minimum dehydration rate is met. For each additional dehydration cycle, increase the dehydration speed by one cycle until the dehydration is complete.

[0113] In this embodiment, a reasonable method for calculating the moisture content Q is designed, which is to take the deviation between the weight of the clothes in the drum during the dehydration process and the weight of the clothes before water intake as the moisture content Q of the clothes, so that the calculated moisture content Q can accurately represent the current moisture content of the clothes.

[0114] The present invention also provides a washing device, which is controlled by the dehydration control method described in any of the above technical solutions.

[0115] The washing equipment of the present invention uses the dehydration control method of the present invention, which enables the washing equipment to reasonably control the dehydration time and dehydration speed according to the material of the clothes, thus ensuring a good dehydration effect on the clothes and avoiding waste of dehydration time.

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.
