Description

Technical Field

[0001] The present application relates to the field of drying equipment control, and in particular, to a drying control method and drying equipment. Background Art

[0002] In the process of drying clothes and other loads, it is found that the heat output by the electric heating device may fluctuate due to certain factors, which may affect the drying progress and effect and reduce the user's drying experience. Summary of the invention

[0003] The embodiments of the present application provide a drying control method and a drying device to at least solve the technical problem of poor drying experience.

[0004] According to a first aspect of an embodiment of the present application, a drying control method is provided, which is applied to a drying duct, wherein an electric heating device for heating a drying airflow is provided in the drying duct, and the drying duct is connected to an air inlet of a clothes processing drum, and the method comprises:

[0005] Obtaining an actual voltage value of the electric heating device;

[0006] If the actual voltage value exceeds the preset target voltage range, the start and stop rhythm of the electric heating device is adjusted so that the change direction of the heat energy value output by the electric heating device is opposite to the change direction of the actual voltage value;

[0007] The step of adjusting the start and stop rhythm of the electric heating device comprises:

[0008] The upper limit value of the first start-stop interval of the electric heating device is adjusted, and the electric heating device is triggered to stop when the temperature of the air inlet exceeds the adjusted upper limit value.

[0009] By adopting this embodiment, the voltage of the electric heating device is detected by obtaining the actual voltage value of the electric heating device. Once the actual voltage value exceeds the target voltage range, it proves that the voltage of the electric heating device fluctuates, which will cause the heat output of the electric heating device to fluctuate. Therefore, the start and stop rhythm of the electric heating device is adjusted so that the start and stop rhythm of the electric heating device can change with the change of the actual voltage value, stabilize the stability of the heat output of the electric heating device, and improve the user's drying experience.

[0010] In combination with the first aspect, in an optional implementation of the embodiment of the present application,

[0011] If the actual voltage value exceeds the preset target voltage range, adjusting the start and stop rhythm of the electric heating device includes:

[0012] If the actual voltage value exceeds the preset target voltage range, the start-stop rhythm of the electric heating device is adjusted by adjusting the range of the first start-stop interval of the electric heating device. The first start-stop interval includes the minimum temperature at which the electric heater needs to be started and the maximum temperature at which the electric heater needs to be stopped.

[0013] When the start-stop rhythm of the electric heating device is adjusted by this implementation, the relevant parameters of the start-stop rhythm will not be changed directly. Instead, the temperature sensor can affect the start-stop of the electric heating device, and the range of the first start-stop interval is adjusted, so that when the temperature detected by the temperature sensor exceeds the adjusted range, the electric heating device starts or brakes, and the start-stop rhythm is adjusted. Since the first start-stop interval is already available, there is no need to set the relevant parameters of the start-stop rhythm, which reduces the number of parameter settings.

[0014] In combination with the first aspect, in an optional implementation of the embodiment of the present application, if the actual voltage value exceeds a preset target voltage interval, the start-stop rhythm of the electric heating device is adjusted by adjusting the interval range of the first start-stop interval, including:

[0015] If the actual voltage value is greater than the upper limit value of the target voltage interval, reducing the upper limit value of the first start-stop interval;

[0016] If the actual voltage value is less than the lower limit value of the target voltage interval, the upper limit value of the first start-stop interval is increased.

[0017] When the present implementation method is used, when the actual voltage value is greater than the upper limit value, the heat output by the electric heating device will increase. At this time, reducing the upper limit value of the first start-stop interval will cause the temperature detected by the temperature sensor to reach the upper limit value of the first start-stop interval in advance, thereby turning off the electric heating device, thereby shortening the start time of the electric heating device, thereby reducing the heat output by the electric heating device, achieving heat stability, and ensuring a good drying experience.

[0018] In combination with the first aspect, in an optional implementation manner of the embodiment of the present application, the method further includes:

[0019] The larger the actual voltage value is, the more the upper limit value of the first start-stop interval is reduced;

[0020] The smaller the actual voltage value is, the more the upper limit value of the first start-stop interval increases.

[0021] When adopting this implementation method, when adjusting the range of the first start-stop interval, the adjustment degree of the range of the first start-stop interval will be adaptively selected according to the actual voltage value, which is beneficial to improving the stability of the heat output by the electric heating device and improving the drying experience.

[0022] In combination with the first aspect, in an optional implementation of the embodiment of the present application, before obtaining the actual voltage value of the electric heating device, the method further includes:

[0023] Obtaining a bus voltage value of the electric heating device;

[0024] If the bus voltage value exceeds a preset reference voltage interval, the start and stop rhythm of the electric heating device is adjusted so that the change direction of the heat energy value output by the electric heating device is opposite to the change direction of the actual voltage value;

[0025] The reference voltage interval includes 300V-350V, the upper limit value of the reference voltage interval is greater than the upper limit value of the target voltage interval, and the lower limit value of the reference voltage interval is greater than the lower limit value of the target voltage interval.

[0026] By adopting this implementation mode, the use of the electric heating device can also be detected by using the bus voltage value, thereby improving the flexibility of control.

[0027] In combination with the first aspect, in an optional implementation of the embodiment of the present application, obtaining the actual voltage value of the electric heating device includes:

[0028] Obtaining the bus voltage of the electric heating device;

[0029] The bus voltage is calculated according to a preset formula to obtain the actual voltage value.

[0030] By adopting this implementation method, the actual voltage value of the electric heating device is difficult to obtain directly or accurately. By obtaining the bus voltage and calculating it using a preset formula, the actual voltage value is obtained, which reduces the difficulty of obtaining the actual voltage value and improves the accuracy of the actual voltage value.

[0031] In combination with the first aspect, in an optional implementation manner of the embodiment of the present application, the preset formula includes:

[0032] Bus voltage = *Actual voltage value.

[0033] By adopting this implementation method, the number of parameters in the formula is small and the calculation is simple, which is conducive to saving computing resources and reducing costs.

[0034] In combination with the first aspect, in an optional implementation of the embodiment of the present application, before obtaining the bus voltage of the electric heating device, the method further includes:

[0035] The motor of the clothes processing drum and the fan in the drying air duct are controlled to maintain a braking state.

[0036] By adopting this implementation method, the voltage of the motor and the fan will not affect the bus voltage of the electric heating device, thereby improving the accuracy of the bus voltage, thereby facilitating improving the accuracy of the actual voltage value.

[0037] According to a second aspect of an embodiment of the present application, a drying equipment control method is provided, including the drying control method described above.

[0038] According to a third aspect of an embodiment of the present application, a drying device is provided, which adopts the above-mentioned drying control method.

[0039] In combination with the third aspect, in an optional implementation of the embodiment of the present application, the drying equipment includes at least one of a dryer and a washer-dryer.

[0040] The technical effects obtained by the above-mentioned second to third aspects are similar to the technical effects obtained by the corresponding technical means in the first aspect, and will not be repeated here. BRIEF DESCRIPTION OF THE DRAWINGS

[0044] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0045] It should be understood that the "plurality" mentioned in this article refers to two or more. In the description of the embodiments of the present application, unless otherwise specified, " / " means or, for example, A / B can mean A or B; "and / or" in this article is only a description of the association relationship of associated objects, indicating that there can be three relationships, for example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone. In addition, in order to facilitate the clear description of the technical solutions of the embodiments of the present application, in the embodiments of the present application, the words "first", "second" and so on are used to distinguish between the same items or similar items with basically the same functions and effects. Those skilled in the art can understand that the words "first", "second" and so on do not limit the quantity and execution order, and the words "first", "second" and so on do not limit certain different

[0046] In addition, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover non-exclusive inclusions. For example, a process, method, system, product, or apparatus that includes a series of steps or elements is not necessarily limited to those steps or elements explicitly listed, but may include other steps or elements not explicitly listed or inherent to such process, method, product, or apparatus.

[0047] Based on the abnormal drying failure (abnormal drying failure: drying heating timeout failure and drying temperature too high failure) that occurred during the long-term experiment of the whole machine, after investigation, it was found that the failure was related to the voltage. The operation under the unconventional voltage of 220V, that is, the high voltage of 253V and the low voltage of 187V, would have a certain impact on the stable output of thermal energy for drying clothes. The instability of thermal energy would cause a large temperature jump in the drying duct, and then cause the automatic temperature limiter to be forced to trip, causing the electric heating device to stop heating, or the manual temperature limiter to be forced to trip, causing the whole machine to report a failure, and finally affecting the drying of clothes and the user's experience. To this end, the present invention proposes a control method to achieve stable output of thermal energy.

[0048] The control method provided in this embodiment solves at least one of the following problems:

[0049] 1. Solve the technical problem of drying abnormality caused by unstable thermal energy under different voltages;

[0050] 2. Solve the problem of accelerated device aging caused by repeated start and stop of the temperature limiter.

[0051] The control method provided in this embodiment has at least one of the following beneficial effects:

[0052] 1. It realizes the output of stable heat energy, which is conducive to the stable drying of clothes;

[0053] 2. Reduce the failure of the whole machine and effectively avoid the accelerated aging of the device;

[0054] 3. It is conducive to improving the user experience.

[0055] In order to solve the technical problem of abnormal drying caused by unstable thermal energy, the present invention determines whether it is necessary to control the threshold of the air inlet temperature sensor bag through the voltage value, and then controls the start and stop time of the electric heating device, and finally satisfies the thermal energy required for drying. This can effectively realize the output of stable thermal energy, which is conducive to the stable drying of clothes.

[0056] Next, a drying control method is provided in detail in the embodiment of the present application. Figure 1 The flow chart of the drying control method shown is that the method is applied to a drying duct, wherein an electric heating device for heating the drying air flow is provided in the drying duct, and the drying duct is connected to the air inlet of the clothing processing drum, and the method includes the following processing process.

[0057] S100: Acquire the actual voltage value of the electric heating device.

[0058] It should be noted that, since the drying air duct may also include other electrical devices after the electric heating device, when obtaining the actual voltage value of the electric heating device, other electrical devices may be turned off to improve the accuracy of obtaining the actual voltage value. In addition, if the actual voltage value cannot be obtained directly, the actual voltage value of the electric heating device may also be obtained by obtaining other electrical parameters and then calculating. Among them, electrical parameters include current, power, etc.

[0059] The actual voltage value refers to the voltage value input to the electric heating device by the outside world.

[0060] S102, if the actual voltage value exceeds the preset target voltage range, adjusting the start and stop rhythm of the electric heating device so that the change direction of the heat energy value output by the electric heating device is opposite to the change direction of the actual voltage value;

[0061] The step of adjusting the start and stop rhythm of the electric heating device comprises:

[0062] The upper limit value of the first start-stop interval of the electric heating device is adjusted, and the electric heating device is triggered to stop when the temperature of the air inlet exceeds the adjusted upper limit value.

[0063] The start-stop rhythm is adjusted by adjusting the maximum temperature at which the electric heating device needs to be stopped. When the electric heating device operates at different voltages, the heat output is different, so a target voltage range is preset. If the actual voltage value is within the target voltage range, it proves that the heat output by the electric heating device is stable. Conversely, if the actual voltage value exceeds the target voltage range, the heat output by the electric heating device will change. Specifically, when the actual voltage value is lower than the lower limit of the target voltage range, the heat output will decrease, and when it is higher than the upper limit of the target voltage range, the heat output will increase.

[0064] Based on the above principle, in order to stabilize the heat output by the electric heating device, the start-stop rhythm of the electric heating device is adjusted. The start-stop rhythm refers to the switching rhythm between starting and braking of the electric heating device. Specifically, when the start duration and / or braking duration changes, it proves that the start-stop rhythm changes.

[0065] After adjusting the start-stop rhythm, the heat energy value output by the electric heating device will change, specifically including two change directions, one is increase and the other is decrease. Therefore, when adjusting the start-stop rhythm, it is only necessary to adjust the change direction of the heat energy value in the opposite direction of the change direction of the actual voltage value. Among them, the change direction of the actual voltage value includes the direction in which the voltage value increases and the direction in which the voltage value decreases.

[0066] By adopting this embodiment, the voltage of the electric heating device is detected by obtaining the actual voltage value of the electric heating device. Once the actual voltage value exceeds the target voltage range, it proves that the voltage of the electric heating device fluctuates, which will cause the heat output of the electric heating device to fluctuate. Therefore, the start and stop rhythm of the electric heating device is adjusted so that the start and stop rhythm of the electric heating device can change with the change of the actual voltage value, stabilize the stability of the heat output of the electric heating device, and improve the user's drying experience.

[0067] In a possible embodiment of the present application, if the actual voltage value exceeds a preset target voltage range, adjusting the start and stop rhythm of the electric heating device includes:

[0068] If the actual voltage value exceeds the preset target voltage interval, the start-stop rhythm of the electric heating device is adjusted by adjusting the interval range of the first start-stop interval of the electric heating device.

[0069] Wherein, the first start-stop interval includes the minimum temperature indicating that the electric heater needs to be started and the maximum temperature indicating that the electric heater needs to be stopped. In one embodiment, a temperature sensor is provided at the air inlet, and when the temperature detected by the temperature sensor exceeds the preset first start-stop interval, the electric heating device is controlled to start or brake.

[0070] For ease of understanding, the temperature sensor at the air inlet can detect the temperature of the drying airflow passing through the air inlet. If the drying airflow temperature exceeds the upper limit of the first start-stop interval, the electric heating device will be controlled to brake. If the drying airflow temperature exceeds the lower limit of the first start-stop interval, the electric heating device will be controlled to start. Based on this, by adjusting the interval range of the first start-stop interval, the start-stop rhythm of the electric heating device can be adjusted. For example, when the upper limit of the first start-stop interval is reduced, the electric heating device will be braked earlier, shortening the start-up time of the electric heating device.

[0071] When the start-stop rhythm of the electric heating device is adjusted by this implementation, the relevant parameters of the start-stop rhythm will not be changed directly. Instead, the temperature sensor can affect the start-stop of the electric heating device, and the range of the first start-stop interval is adjusted, so that when the temperature detected by the temperature sensor exceeds the adjusted range, the electric heating device starts or brakes, and the start-stop rhythm is adjusted. Since the first start-stop interval is already available, there is no need to set the relevant parameters of the start-stop rhythm, which reduces the number of parameter settings.

[0072] Optionally, in an implementation of this embodiment, if the actual voltage value exceeds a preset target voltage interval, adjusting the interval range of the first start-stop interval so that the start-stop rhythm of the electric heating device is adjusted includes:

[0073] If the actual voltage value is greater than the upper limit value of the target voltage interval, reducing the upper limit value of the first start-stop interval;

[0074] If the actual voltage value is less than the lower limit value of the target voltage interval, the upper limit value of the first start-stop interval is increased.

[0075] When reducing the upper limit value of the first start-stop interval, a fixed value or a non-fixed value may be reduced. For example, when reducing a non-fixed value, the value to be reduced may be determined based on the value by which the actual voltage value exceeds the target voltage interval.

[0076] Similarly, when increasing the upper limit value of the first start-stop interval, the value may be increased by a fixed value or a non-fixed value. For example, when increasing a non-fixed value, the value to be increased may be determined based on the value by which the actual voltage value exceeds the target voltage interval.

[0077] When the present implementation method is used, when the actual voltage value is greater than the upper limit value, the heat output by the electric heating device will increase. At this time, reducing the upper limit value of the first start-stop interval will cause the temperature detected by the temperature sensor to reach the upper limit value of the first start-stop interval in advance, thereby turning off the electric heating device, thereby shortening the start time of the electric heating device, thereby reducing the heat output by the electric heating device, achieving heat stability, and ensuring a good drying experience.

[0078] Optionally, in an implementation of this embodiment, the method further includes:

[0079] The larger the actual voltage value is, the more the upper limit value of the first start-stop interval is reduced;

[0080] The smaller the actual voltage value is, the more the upper limit value of the first start-stop interval increases.

[0081] In one embodiment, the reduction range and the increase range of the upper limit value of the first start-stop interval may be determined by means of a preset relationship table or formula, which is not specifically limited in this embodiment.

[0082] When adopting this implementation method, when adjusting the range of the first start-stop interval, the adjustment degree of the range of the first start-stop interval will be adaptively selected according to the actual voltage value, which is beneficial to improving the stability of the heat output by the electric heating device and improving the drying experience.

[0083] Optionally, in an implementation manner of this embodiment, reducing the upper limit value of the first start-stop interval includes:

[0084] reducing the upper limit value of the preset first start-stop interval by a preset first constant;

[0085] The increasing the upper limit value of the first start-stop interval includes:

[0086] The upper limit value of the preset first start-stop interval is increased by a preset second constant.

[0087] In one embodiment, the first constant and the second constant may be equal, for example, both are 5 degrees Celsius.

[0088] By adopting this implementation method, the interval range of the first start-stop interval is adjusted by presetting the first constant and the second constant, which is simple to calculate, helps to save computing resources and reduce costs.

[0089] Optionally, in an implementation of this embodiment, before obtaining the actual voltage value of the electric heating device, the method further includes:

[0090] Obtaining a bus voltage value of the electric heating device;

[0091] If the bus voltage value exceeds a preset reference voltage interval, the start and stop rhythm of the electric heating device is adjusted so that the change direction of the heat energy value output by the electric heating device is opposite to the change direction of the actual voltage value;

[0092] The reference voltage interval includes 300V-350V, the upper limit value of the reference voltage interval is greater than the upper limit value of the target voltage interval, and the lower limit value of the reference voltage interval is greater than the lower limit value of the target voltage interval.

[0093] Preferably, the upper limit of the reference voltage interval is greater than the upper limit of the target voltage interval. times, the lower limit of the reference voltage interval is greater than the lower limit of the target voltage interval times.

[0094] By adopting this implementation mode, the use of the electric heating device can also be detected by using the bus voltage value, thereby improving the flexibility of control.

[0095] Optionally, in an implementation of this embodiment, obtaining the actual voltage value of the electric heating device includes:

[0096] Obtaining the bus voltage of the electric heating device;

[0097] The bus voltage is calculated according to a preset formula to obtain the actual voltage value.

[0098] The bus voltage may be directly measured by a voltage sensor or calculated by current, which is not specifically limited in this embodiment.

[0099] By adopting this implementation method, the actual voltage value of the electric heating device is difficult to obtain directly or accurately. By obtaining the bus voltage and calculating it using a preset formula, the actual voltage value is obtained, which reduces the difficulty of obtaining the actual voltage value and improves the accuracy of the actual voltage value.

[0100] Optionally, in an implementation of this embodiment, the preset formula includes:

[0101] Bus voltage = *Actual voltage value.

[0102] By adopting this implementation method, the number of parameters in the formula is small and the calculation is simple, which is conducive to saving computing resources and reducing costs.

[0103] Optionally, in an implementation of this embodiment, before obtaining the bus voltage of the electric heating device, the method further includes:

[0104] The motor of the clothes processing drum and the fan in the drying air duct are controlled to maintain a braking state.

[0105] By adopting this implementation method, the voltage of the motor and the fan will not affect the bus voltage of the electric heating device, thereby improving the accuracy of the bus voltage, thereby facilitating improving the accuracy of the actual voltage value.

[0106] An embodiment of the present application also provides a drying equipment control method, including the drying control method described above.

[0107] The embodiment of the present application also provides a drying device, which adopts the drying control method described above.

[0108] Optionally, in an implementation of this embodiment, the drying equipment includes at least one of a dryer and a washer-dryer.

[0109] In the above-mentioned embodiments of the present application, the description of each embodiment has its own emphasis. For parts that are not described in detail in a certain embodiment, please refer to the relevant description of other embodiments. The steps shown in the relevant flow chart can be executed in a computer system such as a set of computer executable instructions, and although the logical order is shown in the flow chart, in some cases, the steps shown or described can be executed in an order different from that here. In other words, the order of steps described in the foregoing embodiments is only an example, and it is also within the scope of protection of the embodiments of the present application to reasonably adjust the order of steps based on the content of the embodiments of the present application.

[0110] In a specific implementation of the embodiment of the present application, the drying control method includes the following processing steps:

[0111] like Figure 2 and 3 As shown, in order to solve the technical problem of abnormal drying caused by unstable thermal energy, the present invention determines whether it is necessary to control the threshold value of the air inlet temperature sensor bag through the voltage value, and then controls the start and stop time of the electric heating device, and finally satisfies the thermal energy required for drying. This can effectively achieve the output of stable thermal energy, which is conducive to the stable drying of clothes.

[0112] Specifically, the drying mode is run. After the drying and dehydration is completed, the motor is set not to operate and the fan is not started for 5 seconds to detect the bus voltage of the electric heating device, and then the actual voltage value of the electric heating device is obtained according to Formula 1.

[0113] According to formula 2, t=QR / U², it can be seen that the resistance of the electric heating device remains unchanged. In order to ensure the stable output of thermal energy, it means that t and U² are inversely proportional.

[0114] Since the system can only detect the bus voltage, the actual voltage is determined by the bus voltage. If U bus ≥ 350V, it is judged as a high voltage of 253V; if 300V ≤ U bus ≤ 350V, it is judged as a conventional voltage of 220V; if U bus ≤ 300V, it is judged as a low voltage of 187V;

[0115] If it is judged to be a high voltage of 253V, the upper temperature threshold set by the air inlet temperature sensor is reduced by △T1. (The existing program logic (conventional voltage): when the air inlet temperature reaches 100℃, the electric heating device is turned off; when the air inlet temperature reaches 85℃, the electric heating device is turned on. Here, since the conventional voltage is converted into a high voltage, the air inlet temperature is reset to (100-△T1)℃, then the electric heating device is turned off; when the air inlet temperature reaches 85℃, the electric heating device is turned on.) That is, the opening time of the electric heating device is shortened by △t1, so that the output heat energy tends to be stable.

[0116] If it is judged to be a low voltage of 187V, the upper temperature threshold set by the air inlet temperature sensor is increased by △T1. (The existing program logic (conventional voltage): when the air inlet temperature reaches 100℃, the electric heating device is turned off; when the air inlet temperature reaches 85℃, the electric heating device is turned on. Here, since the conventional voltage is converted to a low voltage, the air inlet temperature is reset to (100+△T2)℃, then the electric heating device is turned off; when the air inlet temperature reaches 85℃, the electric heating device is turned on.) That is, the opening time of the electric heating device is extended by △t2 to achieve the stabilization of the output heat energy.

[0117] If it is judged to be the normal voltage 220V, it will be executed according to the original program logic.

[0118] Formula 1:

[0119] Formula 2: Q=I²Rt=U²t / R.
