Description

Technical Field

[0001] This invention relates to the field of clothing processing equipment technology, and in particular to a drying control method and clothing processing equipment. Background Technology

[0002] The current market's washer-dryer combos typically determine whether the clothes inside the drum are dry by waiting for the temperature difference between the inlet and outlet temperature sensors in the air duct to reach a preset value for a certain period of time, or by directly measuring the moisture content of the clothes using a humidity sensor. However, these methods have significant errors in determining the moisture content of the clothes, which in turn leads to significant errors in determining whether the clothes are dry. Summary of the Invention

[0003] To overcome the problem of drying error caused by directly measuring the moisture content of clothes using temperature or humidity sensors in related technologies, this invention proposes a drying control method and a clothes processing device. This method collects air pressure values ​​inside the clothes processing drum or at its outlet, and determines the change in moisture content of the clothes inside the drum based on the change in air pressure. This allows for a more accurate determination of whether the clothes have reached the required dryness level compared to directly using temperature or humidity sensors.

[0004] The first aspect of this invention provides a drying control method for a garment processing device. The garment processing device has a drying program, which includes a drying and determining stage. The drying control method includes:

[0006] In the above technical solution, determining whether the clothes in the clothes processing drum have reached the drying requirements based on the air pressure value includes:

[0007] During the drying and judging stage, the average air pressure value is collected over at least one preset time period, and the drying requirements of the clothes in the clothes processing drum are determined based on the average air pressure value over at least one preset time period; wherein

[0008] When collecting the average air pressure values ​​over multiple preset time periods, the average of the air pressure values ​​over multiple preset time periods is calculated to determine whether the clothes in the clothes processing drum have reached the drying requirements.

[0009] In the above technical solution, determining whether the clothes in the clothes processing drum have reached the drying requirements based on the air pressure value includes:

[0010] Calculate the average air pressure value P4 in the clothing processing drum within at least one preset time period, compare P4 with the preset air pressure value P5, and determine whether the clothing in the clothing processing drum meets the drying requirements based on the comparison result of P4 and P5.

[0011] When the clothing processing equipment performs the drying and sorting stage, the heating element used to heat the airflow is turned on, and the fan used to power the airflow is turned on.

[0012] In the above technical solution, determining whether the clothes in the clothes processing drum meet the drying requirements based on the comparison results of P4 and P5 includes:

[0013] If P4≤P5, then the clothes in the clothes processing drum are deemed to have reached the drying requirements, and the drying process ends.

[0014] If P4 > P5, it is determined that the air outlet of the clothing processing drum is blocked or the clothes inside the clothing processing drum are tangled, and the air outlet of the clothing processing drum is cleaned.

[0015] The methods for cleaning the air outlet of the garment processing drum in the above technical solution include:

[0016] Rinse the air outlet and calculate the average air pressure P6 in the clothing treatment drum over at least one preset time period after rinsing is completed;

[0017] Compare P6 with the preset air pressure value P5;

[0018] If P6≤P5, then the clothes in the clothes processing drum are deemed to have reached the drying requirements, and the drying process ends.

[0019] If P6 > P5, it is determined that the clothes in the clothes processing drum are tangled, and the process enters an additional drying stage.

[0020] The additional processing stage includes a shaking procedure for shaking the clothes in the clothes processing drum. The shaking procedure includes controlling the clothes processing drum to rotate forward and backward at a preset rhythm for a fourth preset time period.

[0021] In the above technical solution, the drying control method further includes:

[0022] When the garment processing equipment performs an additional drying stage, the shaking procedure is executed m times, where m is an integer greater than or equal to 2, and the average air pressure P7 in the garment processing drum is calculated within at least one preset time period after the shaking procedure is completed.

[0023] Compare the average air pressure P7 with the preset average air pressure P5;

[0024] If P7≤P5, then the clothes in the clothes processing drum are deemed to have reached the drying requirements, and the drying process ends.

[0025] If P7 > P5, it is determined that the clothes in the clothes processing drum are still tangled, and the shaking and untangling procedure is executed again n times, where n is an integer greater than or equal to 2.

[0027] The material of the clothes in the clothes processing drum is obtained.

[0031] Drying control methods also include:

[0032] When the drying program starts, an airtightness test is performed, and the result of the airtightness test determines whether to enter the drying judgment stage.

[0033] If the test results in the airtightness testing stage meet the airtightness requirements, then proceed to the drying and dryness judgment stage;

[0034] If the test results during the airtightness testing phase do not meet the airtightness requirements, an alarm signal will be sent.

[0035] When the drying process is started, the heating element used to heat the airflow is turned on, and the fan used to power the airflow is turned on.

[0036] In the above technical solution, the airtightness testing stage is performed, and the determination of whether to proceed to the drying and sorting stage is based on the test results of the airtightness testing stage, including:

[0037] Get the initial air pressure value P1 inside the clothes processing drum or at the air outlet of the clothes processing drum when the drying program starts, and calculate the average air pressure value P2 in the clothes processing drum within a preset time period when the temperature value inside the clothes processing drum or at the air outlet of the clothes processing drum reaches the first preset temperature value T1.

[0038] Calculate the difference P3 between P2 and P1, and determine whether the difference P3 is within the preset difference interval P31;

[0039] If the difference P3 is within the preset difference range P31, the airtightness of the clothing processing equipment meets the requirements and enters the drying and judging stage.

[0040] If the difference P3 is outside the preset difference range P31, the airtightness of the clothing processing equipment does not meet the airtightness requirements, and an alarm message is sent.

[0041] When the temperature in the garment processing drum reaches the first preset temperature value T1, the heating element used to heat the airflow is controlled to shut off, and the alarm information includes the error code displayed on the garment processing equipment display panel and / or the alarm prompt sound emitted by the voice control system.

[0054] This invention proposes a drying control method and a clothing processing device. By collecting the air pressure value inside the clothing processing drum or at the air outlet of the clothing processing drum, the method judges the change in the moisture content of the clothes inside the clothing processing drum based on the change in the air pressure value, thereby determining whether the clothes inside the clothing processing drum have reached the drying requirements. Compared with the method of directly using temperature sensors or humidity sensors to judge the moisture content of clothes, the drying result is more accurate. Attached Figure Description

[0056] Figure 1 The process control of the drying control method of the clothing processing equipment of the present invention is as follows: Figure 1 ;

[0057] Figure 2 The process control of the drying control method of the clothing processing equipment of the present invention is as follows: Figure 2 . Detailed Implementation

[0058] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Rather, they are merely examples of apparatuses and methods consistent with some aspects of the invention as detailed in the appended claims.

[0059] Current garment processing equipment directly measures the moisture content of clothes using temperature or humidity sensors during the drying process, which introduces errors in determining whether the clothes are dry enough. This invention proposes a drying control method and garment processing equipment that collects air pressure values ​​inside the garment processing drum or at its outlet. By analyzing changes in air pressure, the method determines the change in moisture content of the clothes inside the drum, thereby judging whether the clothes have reached the required dryness level. Compared to directly using temperature or humidity sensors to determine moisture content, this method provides a more accurate assessment of dryness.

[0060] The following is in conjunction with the appendix Figure 1 -Appendix Figure 2The technical solution of this embodiment is described in detail. Unless otherwise specified, the following implementation methods and embodiments can be combined with each other.

[0061] Example

[0062] like Figure 1 and Figure 2 As shown, the first aspect of this invention proposes a drying control method for a garment processing device. The garment processing device has a drying program, which includes a drying and determining stage. The drying control method includes:

[0063] During the drying and judging stage of the clothing processing equipment, the air pressure value inside the clothing processing drum or at the air outlet of the clothing processing drum is collected, and the clothing in the clothing processing drum is judged based on the air pressure value to determine whether the clothing in the clothing processing drum has reached the drying requirements.

[0064] The drying control method proposed in this invention collects the air pressure value inside the clothes processing drum or at the air outlet of the clothes processing drum, and judges the change in the moisture content of the clothes inside the clothes processing drum based on the change in the air pressure value, thereby determining whether the clothes inside the clothes processing drum have reached the drying requirements. Since a large amount of water vapor and hot air are generated inside the clothes processing drum after drying, the air pressure inside the drum changes significantly. Compared with the method of directly using temperature sensors or humidity sensors to judge the moisture content of clothes, the drying result is more accurate.

[0065] Preferably, when collecting air pressure values, the air pressure value collected is the air pressure value at the air outlet of the clothing processing drum.

[0066] Furthermore, the air pressure value is used to determine whether the clothes in the garment processing drum have reached the drying requirements, including:

[0067] During the drying and judging stage, the average air pressure value is collected over at least one preset time period, and the drying requirements of the clothes in the clothes processing drum are determined based on the average air pressure value over at least one preset time period; wherein

[0068] When collecting the average air pressure values ​​over multiple preset time periods, the average of the air pressure values ​​over multiple preset time periods is calculated to determine whether the clothes in the clothes processing drum have reached the drying requirements.

[0069] It is worth noting that the drying and judging stage takes up the longest time in the drying process. The fan and electric heating element are always on during this stage. The air pressure change at the air outlet is most affected by the temperature change. The higher the temperature, the lower the air pressure in the inner cylinder.

[0070] Preferably, when the clothing processing equipment enters the drying and judging stage, when the average value of the air pressure value of multiple preset time periods is collected, the average value of the air pressure value of multiple preset time periods is calculated to determine whether the clothing in the clothing processing drum has reached the drying requirements based on the average air pressure value of multiple preset time periods.

[0071] Further preferably, the duration of each preset time period is set to 3 minutes, and the average value of the air pressure values ​​within multiple 3-minute intervals is calculated. The average of the multiple 3-minute air pressure values ​​is then averaged to obtain a more accurate value P4. After the data is collected, the air pressure value at this time should be the lowest air pressure value in the clothing processing drum, and the corresponding temperature at the air outlet should be the highest temperature in the clothing processing drum. After this condition is met, the main control board uses a fuzzy algorithm to determine the corresponding moisture content of the clothing based on the correspondence between the air pressure value and the moisture content, and thus determines whether the clothing is dry.

[0072] It should be noted that the fuzzy algorithm mentioned above is a correspondence between the air pressure value inside the cylinder and the moisture content of the clothes, that is, the moisture content of the clothes can be calculated from the air pressure value inside the cylinder.

[0073] Specifically, the determination of whether the clothes in the garment processing drum have reached the drying requirements is based on the air pressure value, including:

[0074] Calculate the average air pressure value P4 in the clothing processing drum within at least one preset time period, compare P4 with the preset air pressure value P5, and determine whether the clothing in the clothing processing drum meets the drying requirements based on the comparison result of P4 and P5.

[0075] When the clothing processing equipment performs the drying and sorting stage, the heating element used to heat the airflow is turned on, and the fan used to power the airflow is turned on.

[0076] More specifically, based on the comparison results of P4 and P5, determining whether the clothes in the garment processing drum have met the drying requirements includes:

[0077] If P4≤P5, then the clothes in the clothes processing drum are deemed to have reached the drying requirements, and the drying process ends.

[0078] If P4 > P5, it is determined that the air outlet of the clothing processing drum is blocked or the clothes inside the clothing processing drum are tangled, and the air outlet of the clothing processing drum is cleaned.

[0079] Furthermore, methods for cleaning the air outlet of the garment processing drum include:

[0080] Rinse the air outlet and calculate the average air pressure P6 in the clothing treatment drum over at least one preset time period after rinsing is completed;

[0081] Compare P6 with the preset air pressure value P5;

[0082] If P6≤P5, then the clothes in the clothes processing drum are deemed to have reached the drying requirements, and the drying process ends.

[0083] If P6 > P5, it is determined that the clothes in the clothes processing drum are tangled, and the process enters an additional drying stage.

[0084] The additional processing stage includes a shaking procedure for shaking the clothes in the clothes processing drum. The shaking procedure includes controlling the clothes processing drum to rotate forward and backward at a preset rhythm for a fourth preset time period.

[0085] Specifically, the rinsing valve is opened to flush the air outlet of the garment processing drum (i.e., the air duct opening of the condenser duct). The rinsing valve is open for 2 minutes. After rinsing, the average air pressure over multiple 3-minute intervals is calculated to obtain the average air pressure P6.

[0086] If the average air pressure P6 is less than or equal to the preset air pressure P5, then the clothes in the clothes processing drum are deemed to have reached the drying requirements, and the drying process ends.

[0087] If P7 > P5, it means that the clothes have not yet reached the required dryness level, indicating that the clothes in the clothes processing drum are tangled. At this time, an additional drying stage is entered to shake and loosen the clothes in the clothes processing drum.

[0088] Furthermore, drying control methods also include:

[0089] When the garment processing equipment performs an additional drying stage, the shaking procedure is executed m times, where m is an integer greater than or equal to 2, and the average air pressure P7 in the garment processing drum is calculated within at least one preset time period after the shaking procedure is completed.

[0090] Compare the average air pressure P7 with the preset average air pressure P5;

[0091] If P7≤P5, then the clothes in the clothes processing drum are deemed to have reached the drying requirements, and the drying process ends.

[0092] If P7 > P5, it is determined that the clothes in the clothes processing drum are still tangled, and the shaking and untangling procedure is executed again n times, where n is an integer greater than or equal to 2.

[0093] Specifically, after receiving the shaking signal, the main control board shakes the clothes, entering an additional drying stage. The main control board sends signals to control the motor to perform multiple forward and reverse rotations, completing five shaking and dehydration cycles. Then, it collects air pressure data three times. If the air pressure value at this point meets the preset range, the drying condition is met. If it does not, the control signal for three more shaking cycles is sent to the motor until the air pressure value meets the preset range.

[0094] In any of the above embodiments, the drying control method further includes:

[0095] The material of the clothes in the clothes processing drum is obtained. When determining whether the clothes in the clothes processing drum have reached the drying requirements based on the air pressure values ​​of multiple preset time periods, the number of multiple preset time periods is determined by the material of the clothes.

[0096] Specifically, for clothing made of different materials, such as wool and down, which are highly absorbent, during the longest drying stage (the assessment stage), the number of times air pressure values ​​are collected for down garments should be 1.5 times that for an equivalent weight of cotton or linen, and the number of times for wool garments should be twice that for an equivalent weight of cotton or linen, to ensure that the air pressure values ​​eventually stabilize. {It is worth noting that the number of collections mentioned here refers to multiple preset time periods described above. That is, a single collection only collects the average air pressure within one preset time period; multiple collections collect the average air pressure over multiple preset time periods, and then the average of these multiple preset time periods is calculated.} This ensures more accurate air pressure data.

[0097] In any of the above embodiments, the drying process further includes an air tightness detection stage performed before the drying and judging stage, the air tightness detection stage being used to detect the air tightness of the garment processing equipment.

[0098] Drying control methods also include:

[0099] When the drying program starts, an airtightness test is performed, and the result of the airtightness test determines whether to enter the drying judgment stage.

[0100] If the test results in the airtightness testing stage meet the airtightness requirements, then proceed to the drying and dryness judgment stage;

[0101] If the test results during the airtightness testing phase do not meet the airtightness requirements, an alarm signal will be sent.

[0102] When the drying process is started, the heating element used to heat the airflow is turned on, and the fan used to power the airflow is turned on.

[0103] Furthermore, an airtightness testing phase is performed, and the results of this phase determine whether to proceed to the drying and sorting phase, including:

[0104] Get the initial air pressure value P1 inside the clothes processing drum or at the air outlet of the clothes processing drum when the drying program starts, and calculate the average air pressure value P2 in the clothes processing drum within a preset time period when the temperature value inside the clothes processing drum or at the air outlet of the clothes processing drum reaches the first preset temperature value T1.

[0105] Calculate the difference P3 between P2 and P1, and determine whether the difference P3 is within the preset difference interval P31;

[0106] If the difference P3 is within the preset difference range P31, the airtightness of the clothing processing equipment meets the requirements and enters the drying and judging stage.

[0107] It should be noted that when the difference P3 is within the preset difference range P31, it is further determined whether the temperature of the air outlet is stable. If it is stable, the drying judgment stage is entered.

[0108] It should also be noted that when the temperature at the air outlet fluctuates within a preset range over a preset time period, it indicates that the air outlet temperature has reached a stable value. Specifically, when the temperature inside the garment processing drum stops rising within one minute, it indicates that the temperature has reached a stable state. A temperature tolerance deviation of ±1℃ at the air outlet is considered sufficient to indicate that the temperature has reached a stable value.

[0109] If the difference P3 is outside the preset difference range P31, the airtightness of the clothing processing equipment does not meet the airtightness requirements, and an alarm message is sent.

[0110] When the temperature in the garment processing drum reaches the first preset temperature value T1, the heating element used to heat the airflow is controlled to shut off, and the alarm information includes the error code displayed on the garment processing equipment display panel and / or the alarm prompt sound emitted by the voice control system.

[0111] Specifically, when the drying program starts, the electric heating chamber and fan are activated. A pressure sensor collects the air pressure value P1 at the air outlet of the clothes processing drum. The electric heating element in the air duct is powered on, and the temperature inside the clothes processing drum begins to rise. After the temperature measured by the outlet temperature sensor reaches the set temperature, the electric heating element is disconnected, and the average air pressure value P2 over 3 minutes is collected. The main control board algorithm then calculates the difference P3 between P1 and P2. After obtaining P3, the calculated air pressure difference is compared with the preset value P31. If P3 falls within the preset range of P31, it indicates that the overall airtightness of the machine during the heating phase is normal. If it does not fall within the preset range, a signal is fed back to the main control board, which sends a signal to the display screen to show an air pressure error code, indicating that the drying circulation system has a leakage problem due to prolonged use. After-sales personnel should be contacted to check the overall airtightness and structural damage of the machine.

[0112] In summary, this invention accurately determines the moisture content of clothing by capturing the point where the pressure difference changes most significantly during the drying stage of the entire garment processing equipment and determining whether the pressure difference meets a preset value. Furthermore, pressure control allows for precise judgment of pressure changes throughout the entire drying cycle structure. Different load weights and materials result in different pressure values ​​(the water vapor and heat generated after washing and drying vary depending on the load weight). Once the corresponding pressure difference reaches the preset range, the drying determination is complete. Specifically, the actual measured pressure value is compared with the preset value at each heating stage of the outlet air temperature sensor. The determination is complete once the preset value is reached. The main parameters for determining drying include the initial value, stable value after heating, peak value, and final value of the outlet air temperature sensor. Compared to traditional humidity sensors and the temperature difference between the inlet and outlet air temperature sensors, this method more accurately detects pressure changes within the circulating air duct due to decreased moisture content, thus completing the moisture content test for the clothing.

[0113] A second aspect of this invention also provides a garment processing device, employing the above-described drying control method. The garment processing device includes:
