The temperature sensors and humidity sensors are specially set for drying detection, which increases the cost, and the humidity sensors are easily disturbed and have low detection accuracy. SUMMARY

[0003] The main purpose of the embodiments of the present application is to provide a control method and device of a clothes treatment apparatus, aiming to solve the technical problems of high cost and low accuracy of the existing drying judgment method.

[0019] wherein △t satisfies 0≤△t≤1℃.

[0020] In the example embodiment of the present application, according to the preset condition that the critical temperature value and the first temperature value satisfy, it is determined that the clothes in the clothes processing device have completed drying, wherein the preset condition can comprise:

[0021] T-Tmax>Td;

[0022] wherein T is the first temperature value, Tmax is the critical temperature value, and Td is a preset temperature threshold.

[0023] In the example embodiment of the present application, the preset condition can further comprise:

[0045] The embodiments of the present application provide a drying judgment method of a clothes processing apparatus. The clothes processing apparatus can include a heater. In the embodiments, the heater can heat washing water at the bottom of an outer drum during a washing process to wash clothes. The heater is not operated during a drying process of the clothes. The clothes processing apparatus further includes a temperature sensor disposed at the heater at the bottom of the outer drum to detect a temperature between an inner drum and the outer drum. As shown in Figure 1 、 Figure 2 The method can include steps S101-S103.

[0046] S101, acquiring temperature values in multiple periods collected by the temperature sensor, and determining a critical temperature value of the drying process of the clothes processing apparatus according to the temperature data in the multiple periods.

[0047] S102, acquiring a first temperature value after a first preset time length from the determination of the critical temperature value.

[0048] S103, determining that the critical temperature value and the first temperature value satisfy a preset condition, and judging that the clothes in the clothes processing apparatus have completed drying.

[0049] In the exemplary embodiments of the present application, a scheme for automatically judging drying in a drying stage by means of a temperature sensor for detecting temperature in a water-heated drying drum clothes processing apparatus is provided. The scheme does not need to additionally increase sensors, is more cost-saving, and can provide judgment accuracy, compared with a conventional scheme for judging drying by means of a temperature sensor and a humidity sensor.

[0050] In the exemplary embodiments of the present application, the temperature sensor can be a sensor for detecting the temperature between the inner drum and the outer drum.

[0051] In the exemplary embodiments of the present application, acquiring the temperature data can include:

[0052] The period includes multiple sub-periods.

[0053] Acquiring temperature values in the multiple sub-periods, and taking an average value of the temperature values in the multiple sub-periods as the temperature value in the one period.

[0054] In the exemplary embodiments of the present application, the period can be a first preset time length.

[0055] In the example embodiments of the present application, the temperature (i.e., the temperature value) can be periodically collected according to a preset temperature collection period (i.e., the sub-period described above); every set first preset time length, the average temperature in the first preset time length is calculated according to the collected temperature, and the average temperature in each first preset time length can be taken as a temperature data respectively; wherein the first preset time length can include at least two temperature collection periods, that is, two sub-periods.

[0056] In the example embodiments of the present application, the first preset time length can be defined according to different information of laundry treatment equipment models, different heating powers, different water quantities, etc., and the specific value of the first preset time length is not limited herein.

[0057] In the example embodiments of the present application, for example, the first preset time length can meet but is not limited to 0.5min-2min. Specifically, 1min can be selected, that is, the average temperature is calculated once every 1min.

[0058] In the example embodiments of the present application, the temperature collection period can also be defined according to different information of laundry treatment equipment models, different heating powers, different water quantities, etc., and the specific value of the temperature collection period is not limited herein.

[0059] In the example embodiments of the present application, each temperature collection period can meet but is not limited to the following range: 5s-15s, for example, 12s, 10s, etc. can be selected, that is, temperature collection is performed once every 12s, or once every 10s.

[0060] In the example embodiments of the present application, for example, when the temperature collection period is 12s, if the first preset time length described above is 1min, 5 times of temperature collection can be performed in each first preset time length, and the average of 5 temperatures can be calculated. When the temperature collection period is 10, if the first preset time length described above is 1min, 6 times of temperature collection can be performed in each first preset time length, and the average of 6 temperatures can be calculated.

[0061] In the example embodiments of the present application, before the average temperature in the first preset time length is calculated according to the collected temperature, the method can further include:

[0062] The maximum and minimum values of the plurality of temperatures collected in the first preset time length are removed, and the remaining temperatures in the plurality of temperatures are averaged to obtain the average temperature in the first preset time length.

[0063] In the example embodiments of the present application, the above-mentioned embodiments avoid inaccurate temperature acquisition due to temporary large fluctuations in temperature or temporary failure of the temperature sensor, etc., thereby ensuring the effectiveness of the acquired temperature and improving the accuracy of the drying scheme of the embodiments of the present application.

[0064] In the example embodiments of the present application, the determination of the critical temperature value in the drying process of the clothes processing device according to the temperature data of multiple cycles can include:

[0065] The temperature values in the two consecutive cycles are obtained, defined as T0 and T1.

[0066] It is determined that T1>T0 is satisfied in the n consecutive cycles, and the clothes processing device is controlled to record T1 and set T1=Tmax; wherein n is a positive integer greater than or equal to 5.

[0067] In the example embodiments of the present application, for example, the average temperature in the current first preset time period is compared with the average temperature in the previous first preset time period, and the size relationship between the average temperature in the current first preset time period and the average temperature in the previous first preset time period is obtained.

[0068] In the example embodiments of the present application, if the average temperature in the current first preset time period is T1 and the average temperature in the previous first preset time period is T0, it is determined whether T1>T0 is satisfied to determine the size relationship between T1 and T0. If it is determined that T1>T0 is satisfied in the n consecutive cycles, the clothes processing device is controlled to record T1 and set T1=Tmax; wherein n is a positive integer greater than or equal to 5.

[0069] In the embodiments of the present application, the temperature values T0 and T1 in the two consecutive first preset time periods are obtained in real time, and the size of T1 and T0 is determined. If T1>T0, it indicates that the drying process is in the rising stage, and if T1>T0 is satisfied in the n consecutive cycles, the misjudgment of the critical temperature value can be excluded. Specifically, in the actual drying process, the first cycle satisfies T1>T0, the second cycle satisfies T1=T0, and the third cycle satisfies T1=T0. Some people may think that T1 at this time is the critical temperature value, but in actuality, it is possible that T1>T0 in the fourth cycle, indicating that the drying stage at this time is still in the rising stage and has not reached the steady-state critical position. Therefore, it is necessary to determine that T1>T0 is satisfied in the n consecutive cycles to further determine whether T1 is the critical temperature value.

[0070] In the present embodiment, the critical position is determined in this way, which can avoid misjudgment of the critical position in the drying process, thereby avoiding misjudgment of the entire drying process, accurately determining the drying, and ensuring the completion of the drying of the clothes.

[0071] In some embodiments, the method can further comprise:

[0072] obtaining temperature values in two consecutive periods, defined as T0 and T1;

[0073] determining that the temperature values in n consecutive periods do not satisfy T1 > T0, and controlling the temperature sensor to re-obtain temperature values in two consecutive periods; wherein n is a positive integer greater than or equal to 5.

[0074] In this embodiment, as long as the temperature value in one of the n consecutive periods does not satisfy T1 > T0, the temperature sensor is controlled to re-obtain temperature values in two consecutive periods, and the values of T1 and T0 are compared again. This process eliminates false positives that can occur during the drying rising process, and only when this condition is met can it be further determined whether T1 is a critical temperature value.

[0075] In some embodiments, the specific determination steps can refer to steps 51-53:

[0076] 51. Obtain a first difference value of the average temperature value T1 in the latter one of the two consecutive adjacent first preset time periods within the second preset time period minus the average temperature value T0 in the former one of the two consecutive adjacent first preset time periods within the second preset time period; the second preset time period includes a first preset time period; a is a positive integer greater than or equal to 5;

[0077] 52. When the first difference value detected in the second preset time period is greater than the preset temperature threshold, it is determined that the temperature is in the rising state, and step 51 is returned. When any one of the first difference values detected in the second preset time period is less than or equal to the preset temperature threshold, the average temperature in the latter one of the first preset time periods corresponding to the first difference value less than or equal to the preset temperature threshold is recorded as a possible critical temperature value, and the detection of the first difference value in the next second preset time period is entered. The current rising state is determined by the first difference value in the next second preset time period to determine whether the current rising state is over and enters the stable state;

[0078] 53. When the first difference value detected in the next second preset time period is less than or equal to the preset temperature threshold, it is determined that the rising state is over and has entered the stable state, and it is determined that the state when the possible critical temperature value appears is a critical state, and the possible critical temperature value is taken as the critical temperature value. When any one or more of the first difference values detected in the next second preset time period is greater than the preset temperature threshold, it is determined that the intermediate temperature has fluctuated, but the current temperature is still in the rising state, and step 51 is returned.

[0079] In the exemplary embodiments of the present application, the temperature threshold value can be set according to different models, and the value of the temperature threshold value is not limited in detail herein.

[0080] In the exemplary embodiments of the present application, on the basis of determining how to judge the rising state and the stable state, the transition stage between the rising state and the stable state can be detected, i.e., the stage in which the first difference value changes from being greater than the temperature threshold value to being less than or equal to the temperature threshold value, and the state of the temperature at this stage is taken as the critical state.

[0081] In the exemplary embodiments of the present application, after the critical state is determined, the maximum average temperature when the state transition is performed, i.e., the average temperature peak in the critical state, can be obtained as the critical temperature value Tmax.

[0082] In some embodiments, after the critical temperature value of the laundry treating apparatus in the drying process is determined according to the temperature data of multiple cycles, the method can further include:

[0083] obtaining temperature values in multiple cycles;

[0084] determining that the drying process is in a stable state when the temperature values in the multiple cycles all satisfy Tmax-△t≤Tmax≤Tmax+△t;

[0085] wherein △t satisfies 0≤△t≤1℃.

[0086] In this embodiment, Tmax is taken as the possible critical temperature value, and whether the temperature values in the multiple cycles satisfy Tmax-△t≤Tmax≤Tmax+△t is obtained. If yes, it indicates that the drying process has been in a stable state. If no, then the size relationship between the temperature values T1 and T0 in the two consecutive cycles is re-judged, and the temperature value at the stable state is re-found.

[0087] In the exemplary embodiments of the present application, detecting whether the temperature in the outer drum reaches a stable state can further include:

[0088] obtaining multiple average temperatures in a second preset time period; the second preset time period is greater than the first preset time period;

[0089] judging whether the obtained multiple average temperatures continuously rise according to a comparison result of the multiple average temperatures;

[0090] determining that the temperature reaches a stable state when it is judged that the obtained multiple average temperatures do not continuously rise, and determining that the temperature does not reach a stable state when it is judged that the obtained multiple average temperatures continuously rise.

[0091] In the example embodiments of the present application, the determination of whether the plurality of average temperatures continuously increase according to the comparison result of the plurality of average temperatures can include:

[0092] When the difference between any two consecutive average temperatures in the plurality of average temperatures in the second preset time period is less than or equal to the preset temperature threshold, it is determined that the plurality of average temperatures in the second preset time period do not continuously increase.

[0093] When the difference between any two consecutive average temperatures in the plurality of average temperatures in the second preset time period is greater than the second temperature threshold, it is determined that the plurality of average temperatures in the second preset time period continuously increase. In the example embodiments of the present application, the determination of whether the plurality of average temperatures continuously increase can be the determination of whether the plurality of average temperatures sequentially increase according to the collection time (from front to back). If the plurality of average temperatures sequentially increase, it indicates that the average temperature in the outer drum continuously increases. If the plurality of average temperatures do not sequentially increase, it indicates that the average temperature in the outer drum reaches a stable state.

[0094] In the example embodiments of the present application, the non-sequential increase can include that the plurality of average temperature values remain substantially the same (each average temperature can fluctuate around the same basic temperature, and the fluctuation range can satisfy a preset range threshold); or the first a average temperatures in the plurality of average temperatures (for example, a+b, a and b are positive integers) gradually increase, and the last b average temperature values remain substantially the same. The number of b can be limited, for example, b can be at least 2 or 3.

[0095] In the example embodiments of the present application, when it is determined that the plurality of average temperatures in the second preset time period continuously increase, the temperature data is reacquired, and the determination of whether the temperature between the inner drum and the outer drum reaches a stable state is re-detected until it is determined that the plurality of average temperatures in the second preset time period do not continuously increase, the temperature reaches a stable state, and the temperature T is collected.

[0096] In the example embodiments of the present application, when the temperature reaches a stable state, the temperature at this time can be collected as a first temperature value T, and the determination of whether the clothes in the inner drum have been dried according to the acquired critical temperature value Tmax and the collected first temperature value T.

[0097] In the example embodiments of the present application, if it is determined according to the above determination scheme that the temperature does not reach a stable state, it can be returned to step S101 to acquire a plurality of temperature data in the outer drum, and the size relationship between the plurality of temperature data is reacquired to reacquire a possible critical temperature value.

[0098] In the example embodiments of the present application, the second preset time length can be defined according to different types of laundry treatment equipment, different heating powers, different water amounts, etc. The specific value of the second preset time length is not limited herein.

[0099] In the example embodiments of the present application, for example, the second preset time length can be 3 min-10 min, but is not limited thereto. Specifically, 5 min can be selected, i.e., it can be detected whether the average temperature continuously increases within 5 min.

[0100] In the example embodiments of the present application, if it is detected that the average temperature continuously increases within 5 min, step S101 can be returned to, and if it is detected that the average temperature no longer increases within 5 min, the temperature T after 5 min can be recorded.

[0101] In the example embodiments of the present application, the preset condition can include that T-Tmax>Td, where T is the first temperature value collected after the temperature is stable, Tmax is the critical temperature value, and Td is a preset temperature threshold.

[0102] T-Tmax>Td;

[0103] T-Tmax>Td;

[0104] In the example embodiments of the present application, the temperature threshold Td can be defined according to one or more of different types of laundry treatment equipment, different heating powers, and different water amounts added to the outer drum, etc. The specific value of the temperature threshold Td is not limited herein.

[0105] In the example embodiments of the present application, after the critical temperature value and the collected first temperature value are input into the discriminant, it is determined whether the discriminant is established.

[0106] When the discriminant is established, it is determined that the laundry has been dried.

[0107] When the discriminant is not established, it is determined that the laundry has not been dried.

[0108] In the example embodiments of the present application, the critical temperature value determined in the foregoing scheme and the first temperature value collected after the temperature is stable can be input into a preset discriminant. The discriminant can be defined according to requirements, and the specific discriminant is not limited. The discriminant result can be used to determine whether the laundry in the inner drum has been dried.

[0109] In the example embodiments of the present application, the preset condition can further include that T-Tmax

[0110] If T-Tmax≤Td is determined, the temperature sensor is controlled to reacquire the temperature values in two continuous periods. In the exemplary embodiment of the present application, if the determinant is true, it is determined that the clothes have been dried, and the drying process can be directly ended; if the determinant is not true, it is determined that the clothes have not been dried, and the method returns to step S101 to reexecute the drying determination scheme of the embodiment of the present application.

[0111] In the exemplary embodiment of the present application, a schematic diagram of the embodiment of the present application is given as follows, which can include steps 1-9 as shown in the figure. Figure 2

[0112] 1. Enter the automatic drying determination stage.

[0113] 2. Read a temperature value every 12s, read 5 temperature values continuously, remove the maximum and minimum values in the 5 temperature values, and average the remaining values, i.e., obtain an average temperature every 1min.

[0114] 3. The water temperature value T1 obtained in the latest second, and T0 in the last second.

[0115] 4. Do the multiple 1min continuously satisfy T1>T0?

[0116] 5. If yes, let T1=Tmax, and if no, return to step 3.

[0117] 6. Do the multiple 1min continuously satisfy Tmax-△t≤Tmax≤Tmax+△t? If no, return to step 3; and if yes, enter step 7.

[0118] 7. Record the temperature value T2 after 5min.

[0119] 8. T2-Tmax>Td? If yes, enter step 9; and if no, return to step 3.

[0120] 9. Determine that the drying is completed.

[0121] In the exemplary embodiment of the present application, the method can further include:

[0122] When the time length consumed for acquiring the critical temperature value reaches the preset time length threshold, the critical temperature value is still not determined, the clothes are directly determined to have been dried, and the drying process is exited.

[0123] In the exemplary embodiment of the present application, the time length threshold can be customized according to different machine types, different starting detection times, and the like, and the specific value of the time length threshold is not limited in detail herein.

[0124] ​In the exemplary embodiments of the present application, after determining the critical temperature value, the method can further include calculating the temperature in the barrel of the clothes treatment device by the temperature value detected by the temperature sensor, and determining whether the clothes have been dried according to the temperature in the barrel.

[0125] In the exemplary embodiments of the present application, in the current drying determination scheme, the temperature of the inner drum can be directly measured by the preset temperature sensor, and whether the clothes in the inner drum have been dried can be determined according to the temperature of the inner drum.

[0126] In the exemplary embodiments of the present application, the collected temperature (for example, the average temperature after reaching the temperature steady state) can be converted into the temperature of the inner drum, and the current existing drying determination scheme can be used to determine whether the clothes have been dried according to the converted temperature of the inner drum.

[0127] In the exemplary embodiments of the present application, since the temperature sensor is installed between the outer drum and the inner drum and does not directly contact the inner drum for temperature sensing, the temperature collected by the temperature sensor is generally lower than the real temperature of the inner drum (i.e., the temperature directly used for drying determination). For example, the temperature directly used for determining the switching of the heating pipe in the inner drum is generally 100°C and 95°C, while the temperature used for drying determination by the temperature sensor is 10°C to 20°C lower than the temperature directly used for drying determination in the inner drum. The specific value can be calibrated according to different models. According to this situation, after obtaining the temperature detected by the temperature sensor, a preset temperature difference value (which can be 10°C to 20°C) can be added to obtain the corresponding temperature of the inner drum, and then the corresponding drying process can be performed according to the temperature of the inner drum.

[0128] In the exemplary embodiments of the present application, a specific embodiment of the embodiment of the present application is given below, as shown in FIG. 2, the embodiment can include steps S201-S209: Figure 3

[0130] S202, start timing the steady state determination time t2;

[0131] S203, read the detection value (a value representing the temperature) of the temperature sensor every 12s, continuously read 5 detection values, remove the maximum value and the minimum value in the 5 detection values, and average the remaining 3 detection values to obtain the average temperature, i.e., obtain an average temperature every 1min;

[0132] S204, obtain the average temperature T1 obtained in the last 1min, and obtain the average temperature T0 obtained in the last 1min;

[0133] ​S205, judging whether T1>T0? and recording the judging result, detecting whether t2 reaches 5 min? and detecting whether t1 reaches the set drying time 2 hours? when t1 does not reach two hours and t2 reaches 5 min, entering step S206; when t2 does not reach 5 min, returning to S204; when t1 reaches two hours, considering that the clothes have been dried, the drying can be ended;

[0134] S206, judging whether the average temperature continuously rises within 5 min according to the recorded result? when it is detected that the average temperature continuously rises within 5 min, returning to step S204; when it is detected that the average temperature does not continuously rise within 5 min, executing step S207;

[0135] S207, recording the current average temperature as a first temperature value T and obtaining the recorded temperature T1 before 5 min as a critical temperature value Tmax;
