Description

Technical Field

[0001] The present disclosure relates to the technical field of household appliances, and specifically provides a control method and device for a clothing processing device, and the clothing processing device. Background Art

[0002] Since it is understood that using a clothes dryer to dry clothes has the advantage of not being restricted by space and weather conditions compared to conventional drying methods, many families buy and use clothes dryers to dry clothes. However, existing clothes dryers rotate at a pre-set fixed speed during operation. Rotating at a pre-set fixed speed does not take into account the load of the load to be dried. When the load is large, the load to be dried will accumulate at the bottom of the drum. When the load is small, the load to be dried will stick to the wall of the drum. Both of these make it impossible for the load to be dried to fully contact the drying hot air, and the drying efficiency cannot be kept in the high-efficiency range. Summary of the invention

[0044] Embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although certain embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be construed as being limited to the embodiments described herein, which are instead provided for a more thorough and complete understanding of the present disclosure. It should be understood that the drawings and embodiments of the present disclosure are only for exemplary purposes and are not intended to limit the scope of protection of the present disclosure.

[0045] The term "including" and its variations used in this document are open inclusions, that is, "including but not limited to". The term "based on" means "based at least in part on". The term "one embodiment" means "at least one embodiment"; the term "another embodiment" means "at least one other embodiment"; the term "some embodiments" means "at least some embodiments". Relevant definitions of other terms will be given in the description below. It should be noted that the concepts of "first", "second", etc. mentioned in this disclosure are only used to distinguish different devices, modules or units, and are not used to limit the order or interdependence of the processes performed by these devices, modules or units.

[0046] It should be noted that the modifications of "one" and "plurality" mentioned in the present disclosure are illustrative rather than restrictive, and those skilled in the art should understand that unless otherwise clearly indicated in the context, it should be understood as "one or more".

[0047] Before analyzing the control method of the clothing processing device provided by the embodiment of the present disclosure, we first analyze the reason why the related technology controls the drying drum to rotate at a preset fixed speed, which may not achieve the drying efficiency in the high efficiency range. The clothing processing device mentioned in the embodiment of the present disclosure is a device such as a dryer that dries the load to be dried, so the following analysis takes the dryer as an example.

[0048] According to the working principle of the dryer, during the drying operation, the drying drum of the dryer rotates to drive the load to be dried to roll in the drying drum. The goal is to evenly distribute the load to be dried in the drying drum and increase the contact area between the load to be dried and the drying hot air.

[0049] However, in the prior art, the dryer is set to control the rotation of the drying drum according to a preset fixed speed. When the load to be dried is small, the centrifugal force generated when the aforementioned fixed speed drives the load to be dried to rotate makes the load to be dried adhere to the inner wall of the drying drum, and the contact area between the load to be dried and the drying hot air is small, resulting in low drying efficiency. When the load to be dried is large, when the dryer controls the rotation of the drying drum according to the aforementioned preset fixed speed, the lifting force and centrifugal force generated by it cannot drive the large load to be dried to roll fully. Part of the load to be dried is accumulated at the bottom of the drying drum, and the contact area with the drying hot air is small, which also makes the drying efficiency low.

[0050] In order to solve the above-mentioned problems, an embodiment of the present invention provides a control method for a clothing processing device. The above-mentioned method determines a reasonable first target speed according to the load amount of the load to be dried, and controls the rotation of the drying drum according to the first target speed, so that the lifting force and centrifugal force generated when the drying drum rotates make the load to be dried as evenly as possible in the drying drum, thereby improving the drying efficiency of the load to be dried.

[0051] Figure 1 is a flow chart of a control method for a clothes processing device provided by an embodiment of the present disclosure. Figure 1 As shown, the control method of the clothing processing device provided by the embodiment of the present disclosure includes S110-S130.

[0052] S110: Starting a drying operation on the load to be dried, and determining a first estimated load amount of the load to be dried.

[0053] In the embodiment of the present disclosure, after the dryer is started and performs a drying operation on the load to be dried, the dryer controls the drying drum to rotate. In the process of controlling the drying drum to rotate, the dryer detects a first estimated load amount of the load to be dried by a corresponding detection method.

[0054] In some embodiments, the clothes dryer determines the first estimated load amount of the load to be dried by a load bearing method.

[0055] For example, the dryer first controls the drying drum to shake out the load to be dried, then controls the driving motor to drive the drying drum to rotate an acute angle, and measures the amount of work done when the drum rotates to the acute angle, and then determines the first estimated load of the load to be dried based on the work done.

[0056] For another example, the clothes dryer can control the driving motor to drive the drying drum to rotate according to the set power, and detect the motion characteristic parameters in the drying drum, and then determine the first estimated load of the load to be dried according to the motion characteristic parameters in the drying drum. The kinematic characteristic parameters are parameters used to characterize the kinematic characteristics of a specific object, and the kinematic characteristic parameters may include motion speed, motion angular velocity, motion acceleration or motion angular acceleration. According to the principle of kinematics, under the drive of a specific input power, the kinematic characteristic parameters that can be achieved by the drying drum are different under different load amounts of the load to be dried. Accordingly, the first estimated load amount of the load to be dried can be determined according to the kinematic characteristic parameters detected during the rotation of the clothing processing device. In some specific applications, the clothing processing device pre-stores an association relationship table of kinematic characteristic parameters and estimated load weight under a specific input power. After detecting the motion characteristic parameters of the drying drum, the association relationship table is searched according to the motion characteristic parameters to determine the initial load amount of the load to be dried.

[0057] For another example, in some applications, after the clothes dryer is started, the volume of the clothes in the drying drum is determined by scanning detection, and a first estimated load amount of the load to be dried is estimated based on the volume of the clothes.

[0058] In some other embodiments, the clothes dryer determines the first estimated load amount of the load to be dried by a contact detection method.

[0059] In order to determine the first estimated load amount of the load to be dried by using the contact detection method, the clothes dryer includes a contact sensor in addition to existing components (such as a drying drum, a fan, a heating device, and a controller). The contact sensor can generate a trigger signal when being contacted by the load to be dried, and send the trigger signal to the controller of the clothes dryer.

[0060] In practical applications, the contact sensor can be various types of sensors. In a specific application, the contact sensor can be a conductivity sensor. When a load still having a large water content contacts the two conductive electrodes of the conductivity sensor at the same time, the conductivity sensor can generate a conductivity signal, and the conductivity signal is used as the aforementioned contact signal. In another specific application, the contact sensor can be a pressure sensor. When the load to be dried contacts the pressure sensor, the pressure sensor senses the trigger pressure and generates a pressure detection signal. The aforementioned pressure detection signal is used as the contact signal.

[0061] In the case where the clothes dryer uses a contact sensor to perform contact detection, the aforementioned S110 for determining the load amount to be dried includes S121 - S122 .

[0062] S121: Control the drying drum to rotate according to the initially set speed, and count the running time of the drying drum and the accumulated triggering time of the contact sensor.

[0063] The running time of the drying drum is the accumulated time from the start of the rotation of the drying drum.

[0064] The cumulative triggering duration is the triggering duration generated when the contact sensor is contacted by the load to be dried. In a specific implementation, after receiving the triggering signal, the dryer controller will count the cumulative duration of receiving the triggering signal as the cumulative triggering duration of the contact sensor being triggered by the load to be dried.

[0065] In a specific implementation, since the load to be dried rolls under the drive of the clothes processing barrel, each part of the load to be dried may randomly contact the contact sensor during the rolling process, triggering the contact sensor to generate a contact signal, thereby allowing the controller to accumulate the cumulative trigger time.

[0066] It is known from empirical reasoning and actual tests that the greater the load of the load to be dried in the clothes treatment barrel, the greater the spread volume of the load to be dried in the clothes treatment barrel, and the greater the probability that the load to be dried contacts the contact sensor and triggers the contact sensor to generate a contact signal. Correspondingly, the greater the probability that the contact sensor generates a contact signal, the longer the time for the contact sensor to generate the contact signal during the drying operation, making the controller accumulate the trigger time according to the trigger signal statistics. In other words, the accumulated trigger time is positively correlated with the load of the load to be dried.

[0067] It should be noted that, in the case where the contact sensor is a conductivity sensor, if the conductivity sensor is triggered within a detection cycle, that is, a current loop is formed between its two conductive electrodes to realize conductivity detection, the controller will use the corresponding cycle as the cycle in which the conductivity sensor is in contact with the load to be dried, and accumulate to form the cumulative triggering duration. In some applications, the conductivity sensor simultaneously measures the conductivity of the load to be dried, detects the conductivity within a detection cycle, and generates a corresponding duty cycle signal based on the conductivity. The high potential ratio (or duration) in this duty cycle signal cannot be used to calculate the cumulative triggering duration.

[0068] S122: Determine a first estimated load based on the running time and the accumulated triggering time.

[0069] As analyzed above, the cumulative trigger duration is positively correlated with the load amount of the load to be dried. However, when there is only the cumulative trigger duration and no corresponding reference, the first estimated load amount of the load to be dried cannot be directly determined using the cumulative trigger duration. In the disclosed embodiment, the clothes dryer determines the first estimated load amount by the running time of the drying drum and the cumulative trigger duration.

[0070] In some embodiments, determining the first estimated load amount based on the running time and the accumulated triggering time may include S1221.

[0071] S1221: When the running time reaches the target running time, determine a first estimated load amount according to the accumulated triggering time.

[0072] When the running time of the drying drum reaches the target running time, that is, the running time is long enough, the accumulated triggering time obtained within the corresponding running time also has a relative meaning, which can be used to determine the first estimated load amount of the load to be dried. According to the above analysis, the larger the load amount of the load to be dried, the larger the accumulated triggering time obtained within the target running time, that is, the first estimated load amount is positively correlated with the accumulated triggering time.

[0073] In some specific applications, the controller stores a table of correspondence between trigger duration and load. After determining the cumulative trigger duration, the corresponding table is searched using the cumulative trigger duration to determine the corresponding first estimated load. In other specific applications, the controller stores a mapping function between the trigger duration and the load. After determining the cumulative trigger duration, the cumulative trigger duration is input into the aforementioned mapping function to determine the corresponding first estimated load.

[0074] In some other embodiments, determining the first estimated load based on the running time and the accumulated triggering time may include S1222.

[0075] S1222: When the accumulated triggering duration reaches the target accumulated duration, determine a first estimated load amount according to the running duration.

[0076] In contrast to the aforementioned embodiments, in the embodiments of the present disclosure, the running time of the drying drum is not used as a reference to determine the first estimated load amount of the load to be dried according to the cumulative triggering time. Instead, the cumulative triggering time is used as a reference to determine the first estimated load amount of the load to be dried according to the running time of the drying drum.

[0077] According to the above idea, the reverse analysis is carried out. If the load amount of the load to be dried is larger, the probability that the contact sensor is triggered during the rotation of the drum is greater, and accordingly, the running time of the drying drum required for the cumulative triggering time to reach the target cumulative time is shorter. In other words, when the cumulative triggering time reaches the target cumulative time, the first estimated load amount is inversely correlated with the running time.

[0078] In a specific implementation, the first estimated load amount can be determined according to the running time by using the aforementioned method of searching the corresponding relationship table or the aforementioned method based on the mapping function, which will not be repeated here. The specific implementation process can refer to the previous analysis.

[0079] In some further embodiments, determining the first estimated load amount based on the running time and the accumulated triggering time may include S1223 - S1224 .

[0080] S1223: When one of the running time and the cumulative triggering time reaches the corresponding target time, the ratio of the cumulative triggering time to the running time is calculated.

[0081] According to the previous analysis and experience, the cumulative trigger duration will increase with the increase of the running time, and the ratio between the cumulative trigger duration and the running time is related to the load amount of the load to be dried. After the running time of the drying drum or the cumulative trigger duration reaches the corresponding target duration and is relatively large, the other will also reach the corresponding proportion of duration. At this time, the ratio of the cumulative trigger duration to the running time is calculated, which can eliminate the influence of time accumulation. In other words, by calculating the ratio of the cumulative trigger duration and the running time, it is a value that is positively correlated with the load amount of the load to be dried.

[0082] S1224: Determine a first estimated load according to the duration ratio, where the first estimated load is positively correlated with the duration ratio.

[0083] After obtaining the duration ratio, based on the characteristic that the duration ratio is positively correlated with the load amount of the load to be dried, an estimated load that is positively correlated with the duration ratio can be determined based on the duration ratio. In a specific implementation, the first estimated load amount can be determined based on the running duration by using the aforementioned method of looking up the corresponding relationship table, or by using the aforementioned method based on the mapping function, which will not be repeated here, and the specific implementation process can refer to the analysis in the previous text.

[0084] S120: Determine a first target rotation speed according to the first estimated load.

[0085] In the disclosed embodiment, the first estimated load is positively correlated with the first target speed.

[0086] In some embodiments, the controller stores a data comparison table of load and drum speed. After determining the first estimated load, the first estimated load is used to search the data comparison table to determine the corresponding first target speed.

[0087] In some other specific applications, the controller stores a speed calculation function of the relationship between the load and the drum speed. After determining the first estimated load, the first estimated load is input into the speed calculation function to determine the first target speed.

[0088] In actual applications, the drying drum of a clothes dryer has a corresponding minimum set speed and a maximum set speed. When the drying drum speed is lower than the minimum set speed, the clothes dryer cannot perform the drying operation normally. When the drying drum speed is higher than the maximum set speed, the operation of the clothes dryer causes excessive vibration, or may enter the resonance range and cause severe vibration. If all the first estimated load amounts are brought into the speed calculation function to calculate the first target speed, the problem that the first target speed is lower than the minimum set speed or higher than the maximum set speed may occur.

[0089] In order to avoid the aforementioned problem, in the embodiment of the present disclosure, before using the speed calculation function to determine the first target speed, it is first determined whether the first estimated load is in the interval where the speed calculation function is applicable. The aforementioned interval is represented by a first set load and a second set load, and the first set load is less than the second set load.

[0090] If the first estimated load is within the range of the applicable speed calculation function, the first estimated load is directly processed using the speed calculation function to obtain the first target speed. If the first estimated load is not within the range of the applicable speed calculation function, the first target speed is determined by the following method: (1) if the first estimated load is less than or equal to the first set load, the lowest set speed is used as the first target speed; (2) if the first estimated load is greater than or equal to the second load, the highest set speed is used as the first target speed.

[0091] In actual applications, the controller in the clothes dryer may be a general controller, rather than a dedicated processor specially set for a clothes dryer with a specific signal. In this case, when the clothes dryer is started, the memory will send the stored clothes dryer hardware information to the general processor, and the aforementioned hardware information includes the drum radius of the drying drum. In this case, in order to make the lifting force and centrifugal force generated when the drying drum rotates so that the load to be dried is evenly distributed in the drying drum, the clothes dryer controller determines the first target rotation speed according to the first estimated load and the drum radius.

[0092] In some embodiments, the first target speed is determined based on the first estimated load and the roller radius. The corresponding first set load, second set load, speed calculation function or data comparison table can be determined based on the roller radius, and the first target speed is determined using the aforementioned data.

[0093] In some other examples, the controller stores a speed calculation function including both a load parameter and a roller radius parameter. After determining the roller radius and the first estimated load, the two parameters are simultaneously input into the speed calculation function to obtain a first target speed.

[0094] S130: Control the drying drum to continue rotating at the first target speed.

[0095] After determining the first target rotation speed, the dryer can then control the drying drum to continue rotating according to the first target rotation speed, thereby making the load to be dried as evenly distributed as possible in the drying drum, thereby improving the drying efficiency of the load to be dried.

[0096] According to the control method of the clothing processing device provided by the embodiment of the present disclosure, after starting the drying operation of the load to be dried, the first estimated load of the load to be dried is determined by detecting parameters in the process of initially controlling the drying drum to drive the load to rotate, and then the corresponding first target speed is determined according to the first estimated load, and the drying drum is controlled to continue rotating at the first target speed. The first target speed determined based on the above method roughly matches the load of the load to be dried, and the drying drum is controlled to continue rotating at the first target speed, so that the load to be dried can be distributed as evenly as possible in the drying drum, thereby increasing the specific surface area in contact with the hot air, and thus improving the drying efficiency.

[0097] In actual application, as drying progresses, the moisture in the load to be dried gradually evaporates and the load capacity is reduced, and continuing to control the rotation of the drying drum according to the aforementioned first target speed may not achieve a better drying efficiency. Therefore, after executing the aforementioned S130, the following S140-S150 may also be executed.

[0098] S140: Determine a second estimated load amount of the load to be dried, and determine a second target rotation speed according to the second estimated load amount, wherein the second target rotation speed is positively correlated with the second estimated load amount.

[0099] In a specific implementation, the second estimated load amount of the load to be dried is determined when the drying process reaches a specific time period. For example, in some embodiments, when the clothes dryer determines that the humidity of the load to be dried reaches the target humidity, the second estimated load amount of the load to be dried is determined. In other embodiments, when the clothes dryer determines that the drying time reaches the target time, the second estimated load amount of the load to be dried is re-determined.

[0100] In a specific implementation, the method for determining the second estimated load amount of the load to be dried is the same as the method for determining the first estimated load amount in the previous text, and no further detailed analysis is given here. It should be noted that if the second estimated load amount is determined based on the cumulative triggering time of the contact sensor, a different lookup table or a different mapping function than the previous one is required.

[0101] Similar to the above, after the second estimated load is determined, the second target speed can be determined by a data search method or a data comparison method. It can be imagined that the second target speed is positively correlated with the second estimated load in the above text.

[0102] S130: Control the drying drum to continue rotating at the second target speed.

[0103] After determining the second target speed, the drying drum can be controlled to continue rotating according to the second target speed, so that the contact surface area between the load to be dried and the hot air is higher, thereby achieving higher drying efficiency. In a specific implementation, the aforementioned S140-S150 can be performed multiple times to achieve multiple adjustments of the drying speed.

[0104] The disclosed embodiment also provides a control device for a clothes processing device. Figure 2 Schematic diagram of the structure of the control device of the clothes processing equipment provided by the embodiment of the present disclosure. Figure 2 As shown, the control device 200 of the laundry processing equipment provided by the embodiment of the present disclosure includes a load estimation unit 201, a rotation speed determination unit 202 and a control unit 203.

[0105] The load estimation unit 201 is used to determine a first estimated load of the load to be dried after starting the drying operation of the load to be dried. The speed determination unit 202 is used to determine a first target speed according to the first estimated load, and the first target speed is positively correlated with the first estimated load; the control unit 203 is used to control the drying drum to rotate according to the first target speed.

[0106] In some embodiments, after starting the drying operation of the load to be dried, the control unit 203 controls the drying drum to rotate according to the initially set speed. The load estimation unit 201 counts the running time of the drying drum and the cumulative triggering time of the contact sensor, where the cumulative triggering time is the cumulative time that the load to be dried triggers the contact sensor when the drying drum rotates; then, the first estimated load is determined based on the running time and the cumulative triggering time.

[0107] In some embodiments, when the running time reaches the target running time, the load estimating unit 201 determines a first estimated load according to the accumulated triggering time, and the first estimated load is positively correlated with the accumulated triggering time.

[0108] In some embodiments, when the cumulative trigger duration reaches the target cumulative duration, the load estimation unit 201 determines a first estimated load according to the running duration, and the first estimated load is inversely correlated with the running duration.

[0109] In some embodiments, when one of the running duration and the cumulative trigger duration reaches the corresponding target duration, the load estimation unit 201 calculates the duration ratio of the cumulative trigger duration to the running duration; then determines a first estimated load based on the duration ratio, and the first estimated load is positively correlated with the duration ratio.

[0110] In some embodiments, the control unit 203 controls the drying drum to rotate, including: controlling the drying drum to rotate at a preset fixed speed, or cyclically controlling the drying drum to rotate at a plurality of preset speeds.

[0111] In some embodiments, the speed determination unit 202 adopts the following strategy to determine the first target speed: when the first estimated load is less than or equal to the first set load, the lowest set speed is used as the first target speed; when the first estimated load is greater than or equal to the second set load, the highest set speed is used as the first target speed; when the first estimated load is greater than the first set load but less than the second set load, the speed calculation function is used to process the first estimated load to obtain the first target speed.

[0112] In some embodiments, when determining the first target rotational speed according to the first estimated load, the rotational speed determination unit 202 first obtains and determines the drum radius of the drying drum, and then determines the first target rotational speed according to the first estimated load and the drum radius.

[0113] In some embodiments, after controlling the drying drum to continue rotating at the first target speed, the load estimation unit 201 can also determine a second estimated load of the load to be dried, and the speed determination unit 202 determines the second target speed based on the second estimated load, and the second target speed is positively correlated with the second estimated load, and then the drying drum is controlled to continue rotating at the second target speed.

[0114] In addition to providing the aforementioned control method and control device for the clothes treating apparatus, the embodiments of the present disclosure also provide a clothes treating apparatus. Figure 3 Schematic diagram of the structure of the clothes processing device provided by the present disclosure. Figure 3 As shown, the clothing processing device includes a controller 301, a drying drum 302, and a load estimation device 303.
