Detailed Description

Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present application, as detailed in the appended claims.

It should be noted that, in this document, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising an … …" does not exclude the presence of other like elements in a process, method, article, or apparatus that comprises the element.

For easy understanding, an application scenario to which the present application is applied is described in detail below with reference to fig. 1.

Fig. 1 is a schematic view of an application scenario provided in an embodiment of the present application. Referring to fig. 1, the clothes drying device and the clothes to be dried are included. The clothes to be dried are put into the clothes drying equipment, and the clothes to be dried can be dried by the clothes drying equipment. In the working process of the clothes drying equipment, if the filter screens in the clothes drying equipment are blocked, the clothes drying equipment can send out fault prompt voice to remind a user of cleaning the filter screens of the clothes drying equipment.

In the related art, the clothes dryer may judge whether the lint blocks the filter screen according to a temperature difference between both ends of the filter screen. For example, when the temperature difference between the two ends of the filter screen is small, it can be determined that the filter screen is not blocked, and when the temperature difference between the two ends of the filter screen is large, it can be determined that the filter screen is blocked. However, when judging whether the filter screen is blocked according to the temperature difference, the temperature difference at the two ends of the filter screen is easily affected by the temperature measuring position, the ambient temperature and other factors, so that the temperature difference at the two ends of the filter screen obtained by the clothes dryer can not accurately reflect the state of the filter screen, and the accuracy of judging whether the filter screen is blocked by the clothes dryer is low.

In order to solve the technical problem that the accuracy of judging whether a filter screen is blocked by a clothes dryer in the related art is low, the embodiment of the application provides a fault determining method of clothes dryer, the clothes dryer comprises an exhaust device and a filter device, when the rotating speed of the exhaust device is increased to a first rotating speed value, a first current value of the exhaust device is obtained, a second current value of the exhaust device is determined according to the first rotating speed value, when the first current value is larger than or equal to the second current value, the current of the exhaust device is normal at the moment, the state of the filter device is in an unblocked state, when the first current value is smaller than the second current value, the current of the exhaust device is abnormal at the moment, and the state of the filter device is in a blocked state, so that the working state of the exhaust device can be quickly and accurately reflected through the second current value corresponding to the first current value and the first rotating speed value, and further whether the filter device is blocked can, the accuracy of whether filter equipment judges to block up is improved to the clothing drying equipment.

The technical means shown in the present application will be described in detail below with reference to specific examples. It should be noted that the following embodiments may exist alone or in combination with each other, and description of the same or similar contents is not repeated in different embodiments.

Fig. 2 is a schematic flow chart of a method for determining a failure of a clothes drying apparatus according to an embodiment of the present application. Referring to fig. 2, the method may include:

s201, when the rotating speed of the air exhausting device is increased to a first rotating speed value, a first current value of the air exhausting device is obtained.

The execution main body of the embodiment of the application can be a clothes drying device and also can be a fault determination device of the clothes drying device arranged in the clothes drying device. Wherein the fault determination means of the clothes drying apparatus may be implemented by a combination of software and/or hardware.

The clothes drying equipment can be any equipment with the clothes drying function. For example, the clothes drying device can be a clothes dryer, a washing and drying all-in-one machine and the like. For example, the dryer may be a direct-exhaust dryer, a condensing dryer, or a heat pump dryer.

The clothes drying equipment comprises an air exhaust device and a filtering device. Wherein the air exhaust device is used for drying the internal environment of the clothes dryer. For example, the air exhausting device may be a fan inside the dryer, and the fan may output hot air and cause humid air inside the dryer to be exhausted out of the dryer to keep the air inside the dryer dry. Alternatively, the air exhaust device may also be another device for outputting hot air, which is not limited in the embodiments of the present application.

The filtering device is used for collecting thread scraps falling off from clothes to be dried in the circulating air path so as to prevent the thread scraps from entering the motor. For example, the filtering device may be a lint filter inside the clothes dryer, and when the clothes dryer is in operation, the lint filter may collect lint in air inside the clothes dryer under the action of the exhaust device, so as to prevent the lint from entering the motor and causing a potential safety hazard.

The first rotating speed value is the highest rotating speed value which can be reached when the air exhaust device works. For example, the first rotational speed value may be a rated rotational speed value of the air exhaust device, and when the rotational speed of the air exhaust device increases to the rated rotational speed value, the rotational speed of the air exhaust device stops increasing. For example, the first rotation speed value may be any preset rotation speed value smaller than the rated rotation speed of the air exhaust device, and when the rotation speed of the air exhaust device is increased to the preset rotation speed value, the rotation speed of the air exhaust device stops increasing.

Alternatively, the clothes drying apparatus may determine the first rotation speed value according to the weight of the clothes to be dried. For example, the clothes drying device may obtain the weight of the clothes to be dried according to the gravity sensor in the drum, and determine the first rotation speed value according to the corresponding relationship between the weight of the clothes to be dried and the first rotation speed value. For example, the corresponding relationship between the weight of the clothes to be dried and the first rotation speed value may be as shown in table 1:

TABLE 1

Weight of clothes to be dried	First rotation speed value
		Weight
1	Rotational speed value 1
		Weight 2	Rotational speed value 2
Weight 3	Rotational speed value 3
		……	……

It should be noted that table 1 illustrates the corresponding relationship between the weight of the laundry to be dried and the first rotation speed value by way of example only, and is not limited to the corresponding relationship between the weight of the laundry to be dried and the first rotation speed value.

For example, when the weight of the laundry to be dried is 1, the first rotation speed value determined by the laundry drying apparatus is 1; when the weight of the clothes to be dried is 2, the first rotating speed value determined by the clothes drying equipment is 2; when the weight of the laundry to be dried is weight 3, the first rotation speed value determined by the laundry drying apparatus is rotation speed value 3.

Optionally, the higher the weight of the laundry to be dried in the drum of the clothes drying apparatus, the higher the first rotation speed value of the air exhaust device of the clothes drying apparatus. For example, the first rotation speed value of the clothes drying device for drying 10 kg is rotation speed value a, the first rotation speed value of the clothes drying device for drying 5 kg is rotation speed value B, and rotation speed value a is greater than rotation speed value B. Therefore, when the clothes drying equipment works, the first rotating speed value of the air exhaust device can be reasonably set according to the weight of clothes to be dried in the roller, and the energy consumption of the clothes drying equipment during working can be effectively saved.

Optionally, before the user uses the clothes drying apparatus to dry the clothes, the drying mode may be selected in advance, and the clothes drying apparatus may determine the first rotation speed value according to the drying mode. For example, when drying clothes with a small mass, the user may select a power drying mode in order to reduce the drying time, and the clothes drying apparatus may determine a rotation speed value corresponding to the power drying mode as a first rotation speed value; when the user dries silk clothes, the user can select the soft drying mode, and the clothes drying equipment can determine the rotating speed value corresponding to the soft drying mode as the first rotating speed value.

The first current value is the output current value when the rotating speed of an air exhaust device of the clothes drying equipment is the first rotating speed value. For example, if the first rotation speed value is 1000 rpm, the current value output when the rotation speed of the exhaust device during operation reaches 1000 rpm is the first current value; if the first rotation speed value is 2000 rpm, the current value output when the rotation speed of the exhaust device during working reaches 2000 rpm is the first current value.

Optionally, when the rotation speed of the air exhaust device is increased to the first rotation speed value, the clothes drying equipment may obtain the first current value of the air exhaust device according to the current sensor. Optionally, the clothes drying device may also obtain the first current value of the air exhausting device according to a voltage, a resistance, and the like, which is not limited in the embodiment of the present application.

Next, referring to fig. 3, a process of acquiring a first current value of the air exhausting device when the rotation speed of the air exhausting device is increased to a first rotation speed value will be described in detail.

Fig. 3 is a schematic process diagram for obtaining a first current value of an air exhaust device according to an embodiment of the present application. Referring to fig. 3, a clothes drying apparatus is included. Wherein, the first rotating speed value of the air exhaust device of the clothes drying equipment is 2000 r/min. When the clothes drying equipment starts to work, the rotating speed of the air exhaust device displayed by the display panel of the clothes drying equipment is 1000 revolutions per minute. When the rotating speed of the air exhaust device is increased to a first rotating speed value, the rotating speed of the air exhaust device displayed by a display panel of the clothes drying equipment is 2000 r/min, at the moment, the rotating speed of the air exhaust device is not increased, and the clothes drying equipment acquires a first current value output by the air exhaust device.

And S202, determining the state of the filtering device according to the first current value and the first rotating speed value.

The state of the filter device is a unblocked state or a blocked state. When the state of the filtering device is in a smooth state, the filtering device cannot reduce the clothes drying efficiency of the clothes drying equipment, and when the state of the filtering device is in a blocking state, the filtering device can reduce the clothes drying efficiency of the clothes drying equipment.

The state of the filter device may be determined according to the following possible implementations: and determining a second current value of the air exhaust device according to the first rotating speed value. And the second current value is the corresponding minimum normal working current when the rotating speed of the exhaust device is the first rotating speed value. For example, when the rotation speed of the air exhaust device is increased to the first rotation speed value, if the current value output by the air exhaust device is greater than or equal to the second current value, the air exhaust device works normally, the clothes drying equipment can effectively dry the clothes to be dried, and if the current value output by the air exhaust device is smaller than the second current value, the air exhaust device works abnormally, and the drying efficiency of the clothes drying equipment on the clothes to be dried is low.

Alternatively, the second current value may be determined according to the following feasible implementation: a first preset relationship between the rotation speed value and the current value is obtained. The first preset relationship comprises at least one rotating speed value and a current value corresponding to each rotating speed value. For example, a first preset relationship between the rotation speed value and the current value may be as shown in table 2:

TABLE 2

Value of the rotational speed	Current value
		Rotational speed value 1	Current value 1
Rotational speed value 2	Current value 2
		Rotational speed value 3	Current value 3
……	……

It should be noted that table 2 illustrates the first preset relationship between the rotation speed value and the current value by way of example only, and does not limit the first preset relationship between the rotation speed value and the current value.

And determining a second current value according to the first rotation speed value and the first preset relation. For example, when the first rotation speed value of the air exhaust device is a rotation speed value 1, the corresponding second current value of the air exhaust device is a current value 1; when the first rotating speed value of the air exhaust device is a rotating speed value 2, the corresponding second current value of the air exhaust device is a current value 2; when the first rotating speed value of the air exhaust device is a rotating speed value 3, the corresponding second current value of the air exhaust device is a current value 3.

The state of the filter device is determined based on the first current value and the second current value.

Optionally, when the first current value is greater than or equal to the second current value, the state of the filter device is determined to be a clear state. For example, when the rotation speed of the air exhaust device is increased to a first rotation speed value, if the first current value of the air exhaust device is obtained to be greater than or equal to a second current value corresponding to the first rotation speed value, it is indicated that the blockage degree of the filtering device does not affect the air exhaust device, the air exhaust device works normally, and the clothes drying equipment can effectively dry clothes to be dried.

Optionally, when the first current value is smaller than the second current value, the state of the filter device is determined to be a clogging state. For example, when the rotation speed of the air exhaust device is increased to a first rotation speed value, if the obtained first current value of the air exhaust device is smaller than a second current value corresponding to the first rotation speed value, it is indicated that the blockage degree of the filtering device may affect the air exhaust device, the air exhaust device operates abnormally, and the drying efficiency of the clothes drying equipment on clothes to be dried is low.

And S203, generating fault prompting information according to the state of the filtering device.

And when the state of the filtering device is the blocking state, the clothes drying equipment generates fault prompt information. Optionally, the fault prompt message generated by the clothes drying device may be a prompt tone. For example, when the state of the filter device is a clogging state, the clothes drying apparatus may emit a filter device cleaning prompt sound to remind the user that the filter device is clogged. Optionally, the fault prompt message generated by the clothes drying device can be a buzzing prompt tone and a fault message prompt. For example, when the state of the filter device is a blocked state, the clothes drying apparatus may emit a buzzer warning tone and display failure information of the blocking of the filter device in a display panel of the clothes drying apparatus.

Next, a process of generating the failure indication information according to the state of the filter device will be described in detail with reference to fig. 4A and 4B.

Fig. 4A is a schematic diagram of a process of generating fault notification information according to an embodiment of the present application. Referring to fig. 4A, a clothes drying apparatus is included. When the clothes drying equipment works, the state of the filtering device is a blocking state, and at the moment, the clothes drying equipment can send out voice prompt information of asking for clearing the filtering device so as to remind a user that the filtering device is blocked.

Fig. 4B is a schematic diagram of another process for generating fault notification information according to the embodiment of the present application. See fig. 4B, including a clothes drying apparatus. When the clothes drying equipment works, the state of the filtering device is a blocking state, at the moment, the clothes drying equipment can send out a buzzing prompt tone to remind a user that the clothes drying equipment fails, fault information of blocking of the filtering device is displayed in a display panel of the clothes drying equipment, and the user can determine the failure of the clothes drying equipment according to the fault information displayed in the display panel.

The embodiment of the application provides a method for determining faults of clothes drying equipment, the clothes drying equipment comprises an air exhaust device and a filtering device, when the rotating speed of the air exhaust device is increased to a first rotating speed value, a first current value of the air exhaust device is obtained, a first preset relation between the rotating speed value and the current value is obtained, a second current value of the air exhaust device is determined according to the first rotating speed value and the first preset relation, when the first current value is larger than or equal to the second current value, the state of the filtering device is determined to be an unblocked state, when the first current value is smaller than the second current value, the state of the filtering device is determined to be a blocked state, and when the state of the filtering device is the blocked state, fault prompt information is generated. In the method, the second current value corresponding to the first rotation speed value can be accurately determined according to the first rotation speed value and the first preset relation, and the second current value is the minimum normal working current corresponding to the rotation speed of the air exhaust device reaching the first rotation speed value, so that when the first current value is smaller than the second current value, the current output when the rotation speed of the air exhaust device reaches the first rotation speed value is abnormal, and the state of the filter device can be further determined to be a blocking state. According to the first current value and the second current value, whether the current output when the rotating speed of the air exhaust device reaches the first rotating speed value is normal or not can be quickly and accurately determined, and then whether the filtering device is blocked or not can be accurately determined, so that the accuracy of judging whether the filtering device is blocked or not by the clothes dryer is improved.

On the basis of the embodiment shown in fig. 2, the following describes in detail the process of obtaining the first current value output by the air exhausting device when the rotation speed of the air exhausting device is increased to the first rotation speed value, with reference to fig. 5.

Fig. 5 is a schematic flow chart illustrating obtaining a first current value output by an air exhaust device according to an embodiment of the present application. Referring to fig. 5, the method may include:

and S501, acquiring at least two third current values in a preset time period.

The third current value may be a current value output by the air exhausting device within a preset time period. For example, when the rotation speed of the air exhaust device is increased to the first rotation speed value, 3 current values output by the air exhaust device in a preset time period may be obtained, and the 3 current values output by the air exhaust device may be determined as the third current value. For example, when the rotation speed of the air exhausting device is increased to the first rotation speed value, the current value output by the air exhausting device within 5 minutes may be determined as the third current value. For example, when the rotation speed of the air exhausting device during operation reaches a first rotation speed value, a current value output by the air exhausting device in the first minute and a current value output by the air exhausting device in the third minute are obtained, and the current value output in the first minute and the current value output in the third minute are determined as a third current value.

And S502, determining a first current value according to at least two third current values.

Alternatively, the average of at least two third current values may be determined as the first current value. For example, if the third current value a is 10 ma and the third current value B is 20 ma, the first current value may be 15 ma.

Alternatively, the smallest current value of the at least two third current values may be determined as the first current value. For example, if the third current value a is 10 ma and the third current value B is 20 ma, the first current value may be 10 ma.

Alternatively, when the number of the third current values is greater than or equal to the first threshold value, an average value of the plurality of third current values may be determined as the first current value, and when the number of the third current values is less than the first threshold value, a smallest current value among the plurality of third current values may be determined as the first current value. For example, when the first threshold value is 1000, if the number of the third current values is greater than or equal to 1000, an average value of the plurality of third current values is determined as the first current value; if the number of the third current values is less than 1000, a minimum current value among the plurality of third current values is determined, and the minimum current value is determined as the first current value.

Optionally, when the rotation speed of the exhaust device is increased to the first rotation speed value, a relationship curve between the current value output by the exhaust device and the time in a preset time period may be obtained, and the first current value is determined according to the relationship curve between the current value output by the exhaust device and the time. For example, when the rotation speed of the air exhaust device is increased to a first rotation speed value, a relation curve of the current value output by the air exhaust device within five minutes and time is obtained, the minimum value or the average value of the current value is determined in the relation curve, and then the first current value is determined according to the minimum value or the average value of the current value.

The embodiment of the application provides a fault determining method of clothes drying equipment, the clothes drying equipment comprises an air exhaust device and a filtering device, when the rotating speed of the air exhaust device is increased to a first rotating speed value, at least two third current values are obtained in a preset time period, and the average value of the at least two third current values or the minimum current value of the at least two third current values is determined to be the first current value. In the method, after the rotating speed of the air exhaust device is stabilized at the first rotating speed value, at least two third current values in a preset time period are obtained, so that the accuracy of the obtained third current values is high, the first current value output by the air exhaust device can be accurately determined according to the average value or the minimum value of the third current values, whether the filter device is blocked or not can be accurately determined, and the accuracy of judging whether the filter device is blocked or not by the clothes dryer is improved.

On the basis of any of the above embodiments, the following describes in detail the process of fault determination of the clothes drying apparatus by way of example, with reference to fig. 6.

Fig. 6 is a schematic process diagram of fault determination of a clothes drying apparatus according to an embodiment of the present application. See fig. 6, including a clothes drying apparatus. Wherein, the first rotating speed value of the clothes drying equipment is 2000 rpm. And determining a second current value corresponding to the first rotating speed value according to the first rotating speed value.

Referring to fig. 6, when the rotation speed of the air exhausting device in the clothes drying apparatus is increased to the first rotation speed value, 2000 rpm is displayed on the display panel of the clothes drying apparatus, and at this time, the clothes drying apparatus obtains the first current value output by the air exhausting device according to the current value output by the air exhausting device in the preset time period. When the first current value is smaller than the second current value, the state of the filtering device is a blocking state, the clothes drying equipment can send out a buzzing prompt tone to remind a user that the clothes drying equipment fails, fault information of blocking of the filtering device is displayed on a display panel of the clothes drying equipment, and the user can determine the failure of the clothes drying equipment according to the fault information displayed on the display panel. Therefore, according to the first current value and the second current value of the air exhaust device, whether the current output when the rotating speed of the air exhaust device reaches the first rotating speed value is normal or not can be quickly and accurately determined, whether the filtering device is blocked or not can be accurately determined, and the accuracy of judging whether the filtering device is blocked or not by the clothes dryer is improved.

Next, referring to fig. 7, the influence of the clogging of the filter device on the current value of the air discharging device will be described in detail.

Fig. 7 is a schematic diagram of a change in a current value of an air exhaust device according to an embodiment of the present application. Referring to fig. 7, the axes include the axis in which the filter is in an open state and the axis in which the filter is in a blocked state. The ordinate axis of the coordinate axis is the current value output after the rotating speed of the air exhaust device is increased to the first rotating speed value, and the abscissa axis of the coordinate axis is the time after the rotating speed of the air exhaust device is increased to the first rotating speed value.

Referring to fig. 7, in the coordinate axis of the filter device in the unblocked state, after the rotation speed of the exhaust device is increased to the first rotation speed value, the minimum output current value is 163 milliamperes, and when the filter device is unblocked, the current output by the exhaust device is larger. In the coordinate axis of the filter device in the blocked state, after the rotating speed of the exhaust device is increased to the first rotating speed value, the maximum output current value is 57 milliamperes, and because the first rotating speed value is the same, after the filter device is blocked, the current output by the exhaust device is reduced, therefore, according to the first current value output after the rotating speed of the exhaust device is increased to the first rotating speed value, whether the filter device is blocked can be accurately determined, and the current value cannot be influenced by the ambient temperature, so that the accuracy of judging whether the filter device is blocked by the clothes drying equipment is improved.
