Description

Technical Field

[0001] The present invention relates to the technical field of household appliances, and in particular to a clothing processing device and a control method thereof. Background Art

[0002] A drum washing machine usually requires a door seal at one end of the washing drum inlet. The main function of the door seal is to form a sealed space inside the washing drum with the cooperation of the observation window to ensure that there is no water leakage during the operation of the washing machine.

[0003] The washing tub consists of an outer drum and an inner drum mounted within it. Because both the inner and outer drums are suspended within the washing machine's casing, unbalanced rotation of the inner drum can cause unbalanced vibration. This is particularly true in areas with lower indoor temperatures, where the door seal becomes harder. This reduces the resonant speed of the washing machine and increases its amplitude. This vibration is then transmitted through the door seal to the washing machine casing, causing increased vibration and noise throughout the machine.

[0004] Therefore, there is an urgent need for a clothing processing device and a control method thereof to solve the above problems. Summary of the Invention

[0045] Example 1

[0046] This embodiment provides a clothes processing device that can solve the problem of high vibration and noise during operation of the clothes processing device due to excessive hardness of the door seal. The clothes processing device includes a door seal structure, a hardness detection member, and a heating module.

[0047] Among them, the door sealing structure is arranged at the end of the washing drum of the clothing processing equipment. After the door body of the clothing processing equipment is closed, the door body and the washing drum are sealed through the door sealing structure; the hardness detection part is used to detect the hardness of the door sealing structure; the heating module is used to heat the door sealing structure when the hardness value detected by the hardness detection part exceeds the qualified hardness range, so as to adjust the hardness of the door sealing structure.

[0048] The clothing processing device provided in this embodiment is provided with a hardness detection part and a heating module. When the hardness of the door seal structure exceeds the qualified hardness range, the door seal structure is heated by the heating device to soften the door seal structure. This can reduce the hardness of the door seal structure and make the hardness of the door seal structure appropriate, thereby reducing the noise generated during the operation of the clothing processing device, improving the user experience, enhancing the balance performance of the entire clothing processing device, reducing the wear of the door seal structure, and extending the service life.

[0049] Optionally, the heating module includes a first heating device, a water storage container, a drive element, and a water supply line. The door seal structure is provided with a water inlet. One end of the water supply line is connected to the water storage container, and the other end is connected to the water inlet. The first heating device is used to heat the water in the water storage container, and the drive element is used to pass the hot water heated by the first heating device into the door seal structure through the water supply line and the water inlet. The door seal structure is a pleated structure disposed at the end of the washing tub. The pleated structure forms a water storage chamber, and the water inlet is connected to the water storage chamber. Driven by the drive element, heated water is continuously passed into the water storage chamber through the water inlet. The hot water contacts the door seal structure to achieve heat exchange, thereby heating the door seal structure and reducing its hardness. In this embodiment, as hot water is continuously passed into the water storage chamber, the heat-exchanged water in the water storage chamber continuously overflows from the water storage chamber into the washing tub, causing hot water to continuously flush the door seal structure, maintaining the temperature of the hot water in the water storage chamber, and thus rapidly softening the door seal structure. The water flowing into the washing tub can be directly used as washing water during the washing cycle, reusing water resources and increasing energy efficiency.

[0050] Exemplarily, the water storage container may be a water tank disposed in a housing of the clothing processing device, the first heating device may be an electric heating tube disposed in the water tank, and the driving member may be a water pump disposed on the water supply pipeline.

[0051] Furthermore, a control valve is provided on the water supply pipeline to control the on / off state of the water supply pipeline. The control valve and the driving element are both electrically connected to the control computer board of the laundry processing device to achieve electric control. For example, the control valve is a solenoid valve, which facilitates intelligent control.

[0052] Optionally, a hardness detection block is provided on the door seal structure, and a hardness detection member is disposed on the hardness detection block for detecting the hardness of the hardness detection block. In this embodiment, the hardness detection block is integrally formed with the door seal structure and is made of the same material as the door seal structure. This ensures that the hardness value detected by the hardness detection member is the same as the hardness value of the door seal structure, resulting in more accurate test results. Exemplarily, the hardness detection member is a hardness sensor or a hardness tester.

[0053] In other embodiments, the hardness detection block and the door sealing structure may be designed separately and finally assembled into one.

[0054] like Figure 1 As shown, this embodiment also provides a method for controlling a clothes processing device, which is applied to the clothes processing device as described above. The clothes processing device has a clothes processing program. The method for controlling the clothes processing device includes the following steps:

[0055] S1. Before executing the laundry treatment program, obtain the initial hardness value a0 of the door seal structure through the hardness detection component;

[0056] S2, determining whether the initial hardness value a0 is within a preset hardness qualified range, if so, executing the clothing treatment program; if not, executing step S3;

[0057] S3, controlling the heating module to start and run for a first preset time t1. After the first preset time t1, determining whether the hardness value a of the door seal structure detected by the hardness detection component is within the hardness qualified range under the current environment; if so, executing the clothing treatment program; if not, executing step S4;

[0058] S4, controlling the heating module to continue operating for an additional time t. After the additional time t, determining whether the hardness value a of the door seal structure detected by the hardness detection component is within the hardness qualified range under the current environment, if so, executing the clothing treatment program; if not, executing step S5; the additional time t is less than the first preset time t1;

[0059] S5. Repeat step S4.

[0060] That is, after the clothing processing program is triggered, before the clothing processing program is executed, the hardness of the door seal structure is detected, and when the hardness of the door seal structure does not meet the requirements, the door seal structure is heated by the heating module so that the door seal structure meets the hardness qualified range requirements under the current environment, which solves the problem of high vibration and noise caused by excessive hardness of the door seal structure, improves the balance performance of the entire clothing processing equipment, reduces the wear of the door seal structure, and extends its service life.

[0061] In step S2, the preset hardness qualified range is the hardness range of the door seal structure at normal temperature, and the hardness qualified range can be measured through preliminary tests.

[0062] In steps S3 to S5, the hardness of the door seal structure is tested again after heating the door seal structure for the first preset time t1, which can further ensure that the hardness of the door seal structure meets the qualified requirements before executing the clothing processing program, thereby effectively improving the operating stability of the clothing processing equipment and reducing vibration noise.

[0063] Wherein, before controlling the heating module to start in step S3, the method further includes the following steps: S301, obtaining a first preset time t1 for the heating module to heat the door sealing structure;

[0064] The steps of calculating and obtaining the first preset time length t1 include:

[0065] R1, calculate the hardness difference δa between the initial hardness value a0 and the standard hardness value a1 of the door seal structure;

[0066] R2. Obtain the hardness-heating time relationship curve of the door seal structure;

[0067] R3. Obtain a first preset time t1 according to the hardness difference δa and the hardness-heating time relationship curve.

[0068] In step R1 , the standard hardness value a1 is a hardness value within a preset hardness qualified range.

[0069] In step R2, a curve representing the relationship between the door seal's hardness and heating time is obtained based on previous experimental testing of the door seal. Under a constant ambient temperature, a fitting curve is developed to represent the relationship between the door seal's hardness and heating time. Different hardness-heating time curves can be obtained at different ambient temperatures. During step R2, the corresponding hardness-heating time curve is retrieved based on the current ambient temperature of the laundry processing device.

[0070] In step R3 , when the hardness difference δa is determined, it is substituted into the corresponding hardness-heating time relationship curve to obtain the corresponding first preset heating time t1 .

[0071] Since the first preset duration t1 is obtained based on the hardness-heating duration relationship curve measured in actual tests, under normal circumstances, the door seal structure can reach the qualified hardness range under the current environment after heating for the first preset duration t1. In special circumstances, such as when the ambient temperature is low, the door seal structure may not reach the qualified hardness range under the current environment after the first preset duration t1. Even if the hardness of the door seal structure still does not meet the requirements of the qualified hardness range after heating for the first preset duration t1, the hardness of the door seal structure will not be too far from the qualified hardness at this time. Therefore, the additional duration t can be designed to be shorter than the first preset duration t1. This can shorten the total heating time of the door seal structure, thereby shortening the total washing time.

[0072] Exemplarily, the first preset time length t1 is 30 seconds or 1 minute, and the additional time length t is 10 seconds, 20 seconds, etc.

[0073] Furthermore, in step S3, before controlling the heating module to start, the process also includes the following steps: S302, obtaining the heating temperature T1 of the heating module, and adjusting the heating temperature of the heating module to T1. The heating temperature T1 of the heating module is determined based on the temperature tolerance of the clothes currently being washed in the laundry processing device, and the heating temperature T1 of the heating module is lower than the maximum temperature that the clothes can withstand. This setting can prevent excessive temperatures from damaging the clothes. For example, if the maximum temperature that the clothes can withstand is 40°C, then the value of T1 is less than 40°C.

[0074] Furthermore, when washing clothes made of various materials at the same time, the heating temperature T1 is determined based on the highest temperature that the clothes with the weakest heat resistance can withstand.

[0075] When the heating module includes a first heating device, a water storage container, a driver, and a water supply line, in step S3, while hot water is being supplied to the door seal structure, the water level in the washing tub of the laundry processing device is detected. When the detected water level exceeds a water level threshold, the drainage driver of the laundry processing device is controlled to drain excess water from the washing tub. This arrangement prevents excessive water in the washing tub from affecting subsequent laundry processing programs (such as a wash program). In this embodiment, the water level threshold is the maximum water level corresponding to the user's currently selected laundry processing program, and the drainage driver is the drainage pump of the laundry processing device.

[0076] Furthermore, a water level detection component is provided in the washing tub of the clothes processing device, and the water level detection component is used to detect the water level in the washing tub.

[0077] like Figure 2 As shown, in this embodiment, in step S1, before the laundry treatment program is executed, the ambient temperature T2 of the current environment of the laundry treatment device is detected. In step S3, before the heating module is activated, it is determined whether the ambient temperature T2 is lower than the temperature threshold T. If so, the preset hardness qualification range of the door seal structure is adjusted to the current hardness qualification range. If not, the hardness qualification range of the door seal structure is the preset hardness qualification range; the hardness of the current hardness qualification range is lower than the hardness of the preset hardness qualification range.

[0078] That is, before the execution of the clothing treatment program, the hardness of the door seal structure is detected while simultaneously detecting the ambient temperature T2 of the environment in which the clothing treatment device is located. When the ambient temperature T2 is lower than the temperature threshold T, the qualified hardness range of the door seal structure is adjusted to reduce the hardness of the qualified hardness range of the door seal structure. Due to the low ambient temperature, after the heating of the door seal structure is stopped, the temperature of the door seal structure tends to drop quickly, causing the hardness of the door seal structure to quickly fail to meet the requirements of the qualified hardness range. Therefore, by lowering the hardness of the qualified hardness range, the hardness of the door seal structure can be made lower after heating under low ambient temperature conditions, thereby ensuring that the hardness of the door seal structure is more appropriate during the execution of the clothing treatment program and reducing vibration and noise.

[0079] For example, the temperature threshold T of the ambient temperature is 10°C (actual tests have shown that the hardness of the door seal structure changes differently under different temperature gradients. The lower the temperature, especially when the temperature is below 10°C, the greater the change in hardness). When the ambient temperature is greater than or equal to 10°C, the hardness qualified range of the door seal structure (the preset hardness qualified range) is set to 30-35; when the ambient temperature T2 is below 10°C, the hardness qualified range of the door seal structure (the current hardness qualified range) is set to 25-30.

[0080] In other embodiments, the ambient temperature T2 below 10°C can be divided into multiple temperature intervals, and corresponding hardness acceptance intervals can be designed for each temperature interval. For example, when the ambient temperature T2 is between 0°C and 10°C, the hardness acceptance interval is 25-30; when the ambient temperature T2 is between -5°C and 0°C, the hardness acceptance interval is 20-25. During the specific design, the number of temperature intervals can be selected based on adaptability.

[0081] Furthermore, in step S3, if the detected ambient temperature T2 is lower than the temperature threshold T, the heating duration of the heating module is adjusted from the first preset duration t1 to the second preset duration t2, where the second preset duration t2 is greater than the first preset duration t1. In other words, by increasing the heating duration of the door seal structure, the hardness of the door seal structure is further reduced, allowing the hardness of the door seal structure to be quickly adjusted to meet the current hardness acceptance range.

[0082] Exemplarily, the first preset time length t1 is 1 minute, and the first preset time length t2 is 1 minute and 30 seconds.

[0083] In other embodiments, if the detected ambient temperature T2 is lower than the temperature threshold T, the heating module's heating temperature T1 may be adjusted from the first temperature T10 to the second temperature T11, where the second temperature T11 is higher than the first temperature T10 and lower than the maximum temperature that the clothing can withstand. In other words, by increasing the heating module's heating temperature T1, the hardness of the door seal structure is further reduced, allowing the hardness of the door seal structure to quickly decrease to meet the current hardness acceptance range within the first preset time duration t1.

[0084] Exemplarily, the first temperature T10 and the second temperature T11 differ by 10° C. For example, the first temperature is 30° C. and the second temperature is 40° C.; or, the first temperature is 40° C. and the second temperature is 50° C.

[0085] In a new embodiment, the heating time and the heating temperature of the heating module can also be adjusted simultaneously so that the hardness of the door seal structure can be reduced more quickly to meet the requirements of the current hardness qualified range.

[0086] In this embodiment, the laundry processing device further includes a first temperature detector and a second temperature detector. The first temperature detector is configured to detect the ambient temperature of the laundry processing device, and the second temperature detector is configured to detect the heating temperature of the heating device. The first and second temperature detectors are both communicatively connected to a control computer board of the laundry processing device, so that the control computer board can promptly issue corresponding control instructions based on the temperatures detected by the first and second temperature detectors.

[0087] For example, the first temperature detecting element can be a thermometer or temperature sensor, which is arranged outside the housing of the clothing processing device to accurately detect the ambient temperature of the clothing processing device (such as the balcony temperature or the bathroom temperature). The second temperature detecting element can be a water thermometer or temperature sensor, which is arranged inside the water storage container to accurately detect the water temperature in the water storage container. When the detected water temperature meets the temperature requirement, the control driving element is activated to pass the heated hot water through the water supply pipeline to the door sealing structure.

[0088] In this embodiment, the laundry processing program includes a washing program and a dehydration program. Steps S1 to S5 are performed once before the washing program and the dehydration program are executed.

[0089] Specifically, if the clothing processing device needs to execute the washing program and the dehydration program in sequence, then before the washing program is executed, steps S1 to S5 are executed once to make the hardness of the door seal structure appropriate to avoid generating large noise during the execution of the washing program. After the washing program is completed and before the dehydration program is executed, steps S1 to S5 are executed again. Since after the washing program is completed, the hardness of the door seal structure is likely to no longer meet the qualified hardness requirements under the current environment, and the rotation speed of the inner drum of the clothing processing device during the dehydration program is much greater than the rotation speed during the washing program, if the hardness of the door seal structure is large, it will increase the noise during the operation of the clothing processing device. Therefore, before the dehydration program is executed, the hardness of the door seal structure is detected again, and when the hardness of the door seal structure does not meet the qualified hardness range requirements under the current environment, the door seal structure is heated and softened by the heating module to reduce the hardness of the door seal structure, thereby reducing the vibration noise during the execution of the dehydration program of the clothing processing device.

[0090] Of course, if the clothing processing device only needs to execute the dehydration program, steps S1 to S5 are executed once before the dehydration program is executed to ensure that the hardness of the door sealing structure is appropriate to avoid generating loud noise during the dehydration program.

[0091] Example 2

[0092] This embodiment provides a clothes processing device, which differs from the first embodiment in that:

[0093] In this embodiment, the heating module includes a second heating device, a fan and a heating air duct. The second heating device is arranged on the air outlet path of the fan. The door sealing structure is provided with a vent. One end of the heating air duct is connected to the air outlet of the fan, and the other end is connected to the vent. The fan is used to pass the hot air through the heating air duct and the vent into the door sealing structure. The door sealing structure is a pleated structure arranged at the end of the washing drum. A cavity is formed in the pleated structure, and the vent is connected to the cavity. After the fan and the second heating device are started, the hot air heated by the fan continuously enters the cavity through the vent. The hot air contacts the door sealing structure to realize heat exchange, thereby heating the door sealing structure and reducing the hardness of the door sealing structure. As the hot air continuously enters the cavity, the airflow after heat exchange in the cavity overflows into the washing drum, maintaining the temperature of the hot air in the cavity, so that the door sealing structure can be softened quickly.

[0094] Illustratively, the second heating device may be an electric heating wire disposed in the heating air duct.

[0095] This embodiment further provides a method for controlling a clothes processing device, which is applied to the clothes processing device described above. The clothes processing device has a clothes processing program. The method for controlling the clothes processing device includes the following steps:

[0096] S1. Before executing the laundry treatment program, obtain the initial hardness value a0 of the door seal structure through the hardness detection component;

[0097] S2, determining whether the initial hardness value a0 is within a preset hardness qualified range, if so, executing the clothing treatment program; if not, executing step S3;

[0098] S3, controlling the heating module to start and run for a first preset time t1. After the first preset time t1, determining whether the hardness value a of the door seal structure detected by the hardness detection component is within the hardness qualified range under the current environment; if so, executing the clothing treatment program; if not, executing step S4;

[0099] S4, controlling the heating module to continue operating for an additional time t. After the additional time t, determining whether the hardness value a of the door seal structure detected by the hardness detection component is within the hardness qualified range under the current environment, if so, executing the clothing treatment program; if not, executing step S5; the additional time t is less than the first preset time t1;

[0100] S5. Repeat step S4.

[0101] In this embodiment, the laundry processing apparatus comprises an outer drum and an inner drum coaxially disposed within the outer drum.
