Description

Technical Field

[0001] This application relates to the technical field of electromechanical control, and more specifically, to a care method for a dryer. Background Art

[0002] During the clothing care period, steam spraying is required to achieve the ironing effect. If an ultrasonic generating device is used to vaporize the liquid and then care for the clothing, the sterilization effect will be affected due to the relatively low steam temperature. Therefore, a high-temperature steam generator is generally used to spray steam on the clothing to achieve the effects of high-temperature steam sterilization and ironing.

[0040] Existing steam drying and caring technologies usually use ultrasonic generating devices or other atomizing devices to spray steam for care. Since the sprayed steam has no temperature, it does not have the effect of sterilization. The steam generating device heats water to generate steam and sprays it onto the clothes, simulating the ironing technology of a steam iron. The high-temperature steam can achieve the purpose of sterilizing and removing mites, and the effect of caring for clothes is also more advantageous.

[0041] Figure 1 It is a schematic structural diagram of a dryer provided by an embodiment of the present application. It should be noted that a dryer refers to a device for processing dried objects such as clothes, bed sheets, and fabrics. Dryers include, but are not limited to, washing machines, dryers, dry cleaners, etc. with a drying function. As Figure 1 shown, the dryer 100 includes a cabinet 101, a drying drum 102, a humidity sensor 103, a steam generator 104, a temperature sensor 105, and a controller 106. Each part will be introduced one by one below.

[0042] The drying cylinder 102 is rotatably arranged in the box body 101. The drying cylinder 102 is used to provide a space for the user to place drying objects such as clothes to be processed, and it is also a container for steam drying care and drying operations of the drying objects.

[0043] The humidity sensor 103 is arranged in the drying cylinder 102 and is used to collect the humidity of the drying objects in the cylinder. The steam generator 104 is arranged in the drying cylinder 102 and is used to generate steam to perform steam drying care operations on the drying objects in the cylinder. The temperature sensor 105 is in the drying cylinder 102 and is used to collect the initial temperature and the real-time temperature inside the drying cylinder 102.

[0044] The controller 106 is arranged in the box body 101. The controller 106 can be electrically connected to the humidity sensor 103, the steam generator 104 and the temperature sensor 105 respectively. In addition, the controller 106 can also be independently arranged outside the box body 101. The controller 106 can receive / obtain the relevant data collected by the humidity sensor 103, the steam generator 104 and the temperature sensor 105. The controller 106 is configured to execute the steps as Figure 2 shown, Figure 2 is a flowchart of a control method of a controller in a dryer shown in an exemplary embodiment of the present application. Among them, it at least includes S210 to S230, which are introduced in detail as follows:

[0045] S210: Determine the target positive and negative rotation ratio of the rotating drying cylinder according to the comparison result between the surface area of the drying object and the target preset surface threshold.

[0046] In this embodiment, the surface area of the drying object can be measured by scanning with a scanning device, or a picture of the drying object is collected by an image acquisition device, and then the surface area of the drying object is further analyzed and calculated.

[0047] The target preset surface area threshold in this embodiment is a preset parameter before the dryer leaves the factory. There are multiple preset surface area thresholds preset before the dryer leaves the factory. During the actual use of the dryer, the target preset surface area threshold is selected from multiple preset surface area thresholds according to other data or parameters to be used to select the positive and negative rotation ratio suitable for the drying cylinder.

[0048] S220: Control the drying cylinder to rotate according to the target positive and negative rotation ratio.

[0049] In this embodiment, the target positive and negative rotation ratio suitable for the drying cylinder is determined according to the surface area of the drying object, so that the drying object is evenly dispersed during the rotation process and is easy for steam drying care.

[0050] S230: If it is detected that the humidity of the drying object is greater than or equal to the humidity threshold, calculate the temperature growth rate inside the cylinder according to the initial temperature and the real-time temperature inside the cylinder.

[0051] The temperature threshold is a parameter value pre-set before the dryer leaves the factory, and it is used to determine whether the humidity of the dried items reaches the expected value.

[0052] The initial temperature inside the drum is generally room temperature, such as 15 - 28°C. The real-time temperature inside the drum is the temperature value in the drying drum 102 collected by the temperature sensor 105 in real time.

[0053] An exemplary calculation process for the temperature growth rate inside the drum includes: calculating the difference between the initial temperature inside the drum and the real-time temperature inside the drum, taking the absolute value of this difference, dividing this absolute value by the initial temperature inside the drum, and the calculated quotient value is the temperature growth rate inside the drum.

[0054] If the humidity of the dried items is greater than or equal to the humidity threshold, it indicates that the dried items are suspected of not having received sufficient steam drying care and may require further steam drying care. Therefore, in this embodiment, the temperature growth rate inside the drum is calculated based on the initial temperature inside the drum and the real-time temperature inside the drum, and further the magnitude relationship between the temperature growth rate inside the drum and the preset temperature growth rate is compared to accurately determine whether the dried items have received sufficient steam drying care operations.

[0055] S240: Detect whether the temperature growth rate inside the drum is greater than or equal to the preset temperature growth rate.

[0056] The preset temperature growth rate is a parameter value pre-set before the dryer leaves the factory, such as parameter values like 10%, 0.005, etc. In some embodiments, the preset temperature growth rate can also be an interval value, such as (0.005, 0.007), 10% - 10.5%, etc.

[0057] S250: If it is greater than or equal to, stop the care operation.

[0058] Exemplarily, the temperature growth rate inside the drum is 0.01 and the preset temperature growth rate is 0.008, that is, the temperature growth rate inside the drum is greater than the preset temperature growth rate, then control the steam generator to stop generating steam and stop the steam drying care operation for the dried items.

[0059] In the above process, the controller 106 obtains the humidity of the dried items collected by the humidity sensor 103, and detects whether the humidity of the dried items is less than the humidity threshold; if it is detected that the humidity of the dried items is greater than or equal to the humidity threshold, then obtain the initial temperature inside the drum and the real-time temperature inside the drum of the drying drum 102 collected by the temperature sensor 105 to calculate the temperature growth rate inside the drum; compare the temperature growth rate inside the drum with the preset temperature growth rate, and if the temperature growth rate inside the drum is greater than or equal to the preset temperature growth rate, then timely control the steam generator 104 to stop the steam drying care operation.

[0060] In this embodiment, the target forward and reverse rotation ratio suitable for the drying cylinder is determined according to the surface area of the object to be dried, so that the object to be dried is evenly dispersed during rotation, facilitating steam drying care. Then, it is detected whether the humidity of the object to be dried is greater than or equal to the humidity threshold. When the humidity of the object to be dried is greater than or equal to the humidity threshold, that is, when the steam drying care of the object to be dried is suspected to be incomplete, the temperature growth rate inside the cylinder is calculated based on the initial temperature and the real-time temperature inside the cylinder. If the temperature growth rate is greater than or equal to the preset temperature growth rate, it indicates that the object to be dried has received effective and complete steam drying care, and thus the steam generator is timely controlled to stop the steam drying care operation. In this embodiment, corresponding detections and judgments are respectively made on the humidity and the temperature growth rate to determine whether the object to be dried has received effective and complete steam drying care, and the operation of the steam generator is precisely controlled to ensure the steam drying care effect of the object to be dried.

[0061] In another exemplary embodiment, the controller 106 is further configured to perform the following steps:

[0062] If it is detected that the temperature growth rate inside the cylinder is less than the preset temperature growth rate, then it is detected whether the humidity of the object to be dried at the current moment is greater than or equal to the humidity threshold, and a humidity detection result is obtained;

[0063] Determine whether to stop the care operation according to the humidity detection result.

[0064] That is, in the above S240, when it is detected that the temperature growth rate inside the cylinder is less than the preset temperature growth rate, the magnitude relationship between the humidity of the object to be dried at the current moment and the humidity threshold is detected again, that is, the humidity detection result. Among them, the humidity detection result includes the detection result indicating that the humidity of the object to be dried at the current moment is greater than or equal to the humidity threshold, and the detection result indicating that the humidity of the object to be dried at the current moment is less than the humidity threshold.

[0065] This embodiment illustrates the control method when it is detected that the temperature growth rate inside the cylinder is less than the preset temperature growth rate. Detecting that the temperature growth rate inside the cylinder is less than the preset temperature growth rate indicates that the object to be dried has not received sufficient steam drying care. Then, it is necessary to continue the steam drying care for it, and it is detected again whether the humidity of the object to be dried is greater than or equal to the humidity threshold, so as to monitor the humidity of the object to be dried in real time, and determine whether to control the steam generator to stop the steam drying care operation according to the humidity detection result, so as to ensure that the object to be dried receives sufficient steam drying care and improve the steam drying care effect of the object to be dried.

[0066] In another exemplary embodiment, the controller 106 is further configured to perform the following steps:

[0067] If the humidity detection result indicates that the humidity of the object to be dried is less than the humidity threshold, stop the care operation.

[0068] In this embodiment, if the humidity of the dried item is detected to be less than the humidity threshold, it indicates that the dried item has received sufficient steam drying care. Then, the steam generator is controlled to stop the steam drying care operation to avoid over-steaming the dried item and thus prevent damage to the dried item.

[0069] In another exemplary embodiment, the controller 106 is further configured to perform the following steps:

[0070] If the comparison result indicates that the surface area of the dried item is greater than the target preset surface area threshold, the target forward and reverse rotation ratio is the first forward and reverse rotation ratio;

[0071] If the comparison result indicates that the surface area of the dried item is less than the target preset surface area threshold, the target forward and reverse rotation ratio is the second forward and reverse rotation ratio.

[0072] Exemplarily, the target preset surface area threshold is 0.2 ㎡; the first forward and reverse rotation ratio is 1:1, and the second forward and reverse rotation ratio is 2:1. If the surface area of the dried item is 0.1 ㎡, which is less than the target preset surface area threshold, the drying drum is controlled to rotate according to the forward and reverse 1:1 rotation ratio; if the surface area of the dried item is 0.3 ㎡, which is greater than the target preset surface area threshold, the drying drum is controlled to rotate according to the forward and reverse 2:1 rotation ratio.

[0073] In this embodiment, by comparing the surface area of the dried item with the target preset surface area threshold, the dried item with a surface area greater than the target preset surface area threshold is defined as a large-sized dried item, and the drying drum is controlled to rotate according to the first forward and reverse rotation ratio, so that the dried item is evenly distributed and entanglement is prevented. If it is detected that the surface area of the dried item is less than the target preset surface area threshold, the drying drum is controlled to rotate according to the second forward and reverse rotation ratio. In this embodiment, the appropriate forward and reverse rotation ratio of the drying drum is selected according to the surface area of the dried item to control the rotation of the drying drum, so that the dried item is evenly distributed and entanglement is avoided.

[0074] In another exemplary embodiment, the type of the dried item is matched with the preset type, and the target preset surface area threshold corresponding to the successfully matched preset type is obtained. Herein, the type can be defined as the material type or can be defined as the use type according to the specific use of the dried item. The following is an exemplary description of the material type:

[0075] Please refer to Figure 3 as shown Figure 3 which is a schematic structural diagram of another clothes dryer involved in the present application. Compared with Figure 1 the clothes dryer shown Figure 3The dryer shown also includes: a material type detection device 107 for detecting the material type of the drying object. For example, when clothes are placed in the drying cylinder 102 and the door is closed and the start program is selected, the material type detection device 107 scans the clothes to obtain their material type information. Among them, the material type detection device 107 can be an RFID (Radio Frequency Identification) reader, which obtains the material type information of the clothes by identifying the clothes label; the material type detection device 107 can also be a barcode scanner, which obtains the material type information by scanning the barcode on the clothes label. The present application does not limit the specific type of the material type detection device 107 and the method for detecting the material type of the drying object.

[0076] The controller 106 in this embodiment is further configured to perform the following steps:

[0077] Match the type of the drying object with a preset type to obtain the preset type with a successful match;

[0078] Obtain the target preset surface area threshold corresponding to the preset type with a successful match.

[0079] Exemplarily, for drying objects with the same surface area but different material types, if the drying cylinder is rotated according to the same forward and reverse rotation ratio, their dispersion degrees may be different, resulting in uneven dispersion of some material types of drying objects and affecting the effect of steam drying and care. In this embodiment, different subsequent steam amounts, steam care frequencies, etc. can also be set for different material types of clothes to meet different user needs and ensure that the drying object achieves the effect of ironing and removing wrinkles.

[0080] Exemplarily, as shown in Table 1, Table 1 is a relationship table between preset material types and preset surface area thresholds.

[0081] Each preset material type corresponds to a corresponding preset surface area threshold.

[0082] Preset material type Preset surface area threshold (㎡) Cotton 0.020 Linen 0.010 Silk 0.005 Chemical fiber 0.015 …… ……

[0083] Table 1

[0084] If it is detected that the material type of the drying object is silk, obtain the preset surface area threshold corresponding to the silk preset material type as the target preset surface area threshold, that is, the target preset surface area threshold is 0.005 ㎡.

[0085] In this embodiment, by confirming the type of the drying object, the target preset surface area threshold is obtained through matching. This embodiment considers the influence of the type of the drying object in the early stage of the steam drying care process. Because for drying objects with the same surface area but different types, the preset surface area thresholds for dividing whether they are large items may be different. This embodiment determines the target preset surface area threshold from multiple preset surface area thresholds according to the type of the drying object, and can more accurately divide whether it is a large item.

[0086] In another exemplary embodiment, as Figure 4 shown, Figure 4 is a schematic structural diagram of another clothes dryer involved in the present application. Compared with the clothes dryer Figure 1 shown, Figure 4 the clothes dryer shown also includes: a timer 108 for recording various durations of the clothes dryer, and in this example, it records the preheating duration. Among them, the timer 108 can record each critical moment, such as the running / stopping moment of the clothes dryer 100, the starting or stopping moment of the steam generator 104, etc.

[0087] The controller 106 in this embodiment is further configured to execute the following steps:

[0088] Determine the preset preheating duration according to the weight of the drying object;

[0089] Perform a preheating operation on the drying object and record the preheating duration;

[0090] If the preheating duration is greater than or equal to the preset preheating duration, perform a steam drying care operation on the drying object according to the preset steam care frequency corresponding to the successfully matched preset weight range.

[0091] The preheating duration in this embodiment is a parameter value preset before the clothes dryer leaves the factory.

[0092] In this embodiment, a preheating operation is performed on the drying object before the steam drying care, and when it is detected that the preheating duration is greater than or equal to the preset preheating duration, the preheating operation is stopped, providing a temperature basis for the subsequent steam drying care to quickly rise to the temperature required for the steam drying care. Subsequently, a steam drying care operation is performed on the drying object according to the preset steam care frequency corresponding to the successfully matched preset weight range.

[0093] In another exemplary embodiment, as Figure 5 shown, Figure 5 is a schematic structural diagram of another clothes dryer involved in the present application. Compared with the clothes dryer Figure 1 shown, Figure 5The dryer shown also includes: a weighing device 109 for weighing the weight of the drying object; Exemplarily, the user places the drying object in the drying drum 102, and after closing the drum door, the weighing device 109 weighs the drying object, records the total weight in the drying drum 102 at the current moment, and subtracts the initial weight in the drying drum 102 from the total weight. The obtained weight difference is the weight of the drying object. The present application does not limit the specific type of the weighing device 109 and the method of weighing the weight of the drying object.

[0094] The controller 106 in this embodiment is further configured to perform the following steps:

[0095] Obtain the weight of the drying object;

[0096] Match the weight of the drying object with a preset weight range to obtain a successfully matched preset weight range;

[0097] Perform a steam drying and caring operation on the drying object according to the preset steam caring frequency corresponding to the successfully matched preset weight range.

[0098] Exemplarily, as shown in Table 2, Table 2 is a relationship table between the preset weight range and the preset steam caring frequency. Among them, each preset weight range corresponds to a corresponding steam caring frequency.

[0099] Preset weight range (kg) Preset steam care frequency (times / second) 1 to 3 20 3 to 5 15 5 to 7 10 7 to 9 5

[0100] Table 2

[0101] If the weight of the drying object is 6 kg, that is, it matches the preset weight range of (5, 7) in Table 2, and according to the corresponding preset steam caring frequency of 10 times / second, control the steam generator to perform a steam drying and caring operation on the drying object.

[0102] In this embodiment, corresponding preset weight ranges are matched for drying objects of different weights, and a steam drying and caring operation is performed on the drying object according to the preset steam caring frequency corresponding to the preset weight range. This embodiment adapts the corresponding preset steam caring frequency according to the weight of the drying object to improve the steam drying and caring effect of the drying object.

[0103] In another exemplary embodiment, the preset weight range includes a first preset weight range, a second preset weight range, and a third preset weight range; the controller 106 is further configured to perform the following steps:

[0104] If the successfully matched preset weight range is the first preset weight range, perform a steam drying and caring operation on the drying object according to the first preset steam caring frequency;

[0105] If the successfully matched preset weight range is the second preset weight range, perform a steam drying and caring operation on the drying object according to the second preset steam caring frequency;

[0106] If the preset weight range with a successful match is the third preset weight range, perform a steam drying care operation on the dried item according to the third preset steam care frequency.

[0107] Among them, the first preset weight range, the second preset weight range, and the third preset weight range do not overlap, and the preset steam care frequencies corresponding to the three preset weight ranges are different from each other. For example, the first preset weight range is (1 kg, 4 kg), and the corresponding preset steam care frequency is 20 times / second; the second preset weight range is [4 kg, 7 kg], and the corresponding preset steam care frequency is 15 times / second; the third preset weight range is (7 kg, 10 kg), and the corresponding preset steam care frequency is 10 times / second.

[0108] In this embodiment, the corresponding preset weight range is matched according to the weight of the dried item, and the preset steam care frequency corresponding to the successfully matched weight range is adapted, so as to control the steam generator to perform a steam drying care operation on the dried item according to the adapted preset steam care frequency, so as to improve the steam drying care effect of the dried item.

[0109] In another exemplary embodiment, the controller 106 is further configured to perform the following steps:

[0110] Obtain the humidity of the dried item and detect whether the humidity of the dried item is less than the humidity threshold;

[0111] If the humidity of the dried item is less than the humidity threshold, stop the care operation.

[0112] By detecting the humidity of the dried item after the steam drying care, the steam drying care effect of the dried item can be intuitively reflected. For example, the humidity of the dried item is 1 unit, and the humidity threshold is 8 units, that is, the humidity of the dried item is less than the humidity threshold, which indicates that a complete steam drying care process has been performed on the dried item.

[0113] In this embodiment, it is detected that the humidity of the dried item is less than the humidity threshold, indicating that the dried item has received sufficient steam drying care, and then the steam generator is controlled to stop the steam drying care operation, so as to avoid excessive steam drying care operation on the dried item, thereby avoiding damage to the dried item.

[0114] In another exemplary embodiment, the controller 106 is further configured to perform the following steps:

[0115] Obtain the initial temperature in the drum and the real-time temperature in the drum;

[0116] Perform a subtraction operation on the real-time temperature in the drum and the initial temperature in the drum to obtain a temperature difference;

[0117] Perform a division operation on the temperature difference and the initial temperature inside the drum, and use the obtained quotient value as the temperature growth rate.

[0118] Exemplarily, Figure 1 the temperature sensors 105 in respectively collect the initial temperature 15°C inside the drying drum 102 and the real-time temperature 35°C inside the drum. The controller 106 calculates 35°C - 15°C to obtain a temperature difference of 20°C; divides 20°C by 35°C to calculate a quotient value of 4 / 7, which is the temperature growth rate in this embodiment.

[0119] In this embodiment, according to the real-time temperature inside the drum and the initial temperature inside the drum, a temperature difference is calculated through a simple subtraction operation; then, a simple division operation is performed on the temperature difference and the initial temperature inside the drum, and the obtained quotient value is used as the temperature growth rate to quickly and simply determine the temperature growth rate.

[0120] In another exemplary embodiment of the present application, the control method of the controller in the dryer is described in detail. For details, please refer to Figure 6 , Figure 6 which is a flowchart of another control method of the controller in a dryer shown in another exemplary embodiment of the present application. It at least includes S610 to S690, which are introduced in detail as follows:

[0121] S610: Determine the corresponding target preset surface area threshold according to the type of the drying object.

[0122] Please refer to Figure 7 , Figure 7 which is a schematic structural diagram of another dryer involved in the present application. Compared with the dryer shown in Figure 1 , Figure 7 the dryer shown in Figure 1 further includes: a material type detection device 107 for detecting the material type of the drying object; a timer 108 for recording the preheating duration of the dryer; a weighing device 109 for weighing the drying object.

[0123] The controller 106 obtains the material type information of the drying object collected by the material type detection device 107, and determines the target preset surface area threshold from multiple preset surface area thresholds according to the material type of the drying object, for subsequent judgment of whether the drying object is a large-piece type drying object.

[0124] S620: Detect whether the surface area of the drying object is greater than the target preset surface area threshold.

[0125] This step is to judge whether the drying object is a large-piece type drying object according to the size of the surface area of the drying object, specifically by comparing the surface area of the drying object with the target preset surface area threshold.

[0126] S630: If it is detected that the surface area of the drying object is greater than the target preset surface area threshold, control the drying cylinder to rotate according to the first forward and reverse rotation ratio.

[0127] S640: If it is detected that the surface area of the drying object is less than the target preset surface area threshold, control the drying cylinder to rotate according to the second forward and reverse rotation ratio.

[0128] The above first forward and reverse rotation ratio and the second forward and reverse rotation ratio are different, and the specific ratio values are adjusted according to the actual situation.

[0129] S650: Obtain the preset steam care frequency corresponding to the weight of the drying object.

[0130] Figure 7 The weighing device 109 in weighs the drying object to obtain the weight of the drying object. The controller 106 determines the corresponding preset steam care frequency according to the weight of the drying object, and then controls the steam generator to perform steam drying care operations on the drying object according to the preset steam care frequency.

[0131] S660: Detect whether the preheating duration is greater than or equal to the preset duration.

[0132] Figure 7 The timer 108 in starts timing from the moment when the dryer starts preheating and records the current moment to calculate the preheating duration of the dryer. For example, if the moment when the dryer starts preheating is 10:00 and the current moment is 10:20, the preheating duration of the dryer is 20 minutes.

[0133] S670: If it is detected that the preheating duration is greater than or equal to the preset duration, control the steam generator to perform steam drying care operations on the drying object according to the steam care frequency.

[0134] If it is detected that the running preheating is greater than or equal to the preset duration, it indicates that the pre - preparation for the steam care operation has been fully completed, providing a temperature basis for the subsequent steam drying care to quickly rise to the temperature required for the steam drying care.

[0135] S680: Detect whether the humidity of the drying object is less than the humidity threshold.

[0136] Humidity is a parameter that can intuitively represent whether the steam drying care effect of the drying object reaches the expected value. If the humidity of the drying object is less than the humidity threshold, it has received sufficient steam drying care; if the humidity of the drying object is greater than or equal to the humidity threshold, it indicates that the drying object is suspected of not receiving sufficient steam drying care and may require further steam drying care.

[0137] S690: If it is detected that the humidity of the drying object is greater than or equal to the humidity threshold, detect whether the temperature growth rate in the cylinder is greater than or equal to the preset temperature growth rate.

[0138] If the humidity of the dried object is greater than or equal to the humidity threshold, it indicates that the dried object is suspected of not receiving sufficient steam drying care. It is necessary to further calculate the temperature growth rate inside the drying cylinder. If the temperature growth rate inside the cylinder is greater than or equal to the preset temperature growth rate, it indicates that the dried object needs to continue the steam drying care operation; if the temperature growth rate inside the cylinder is less than the preset temperature growth rate, it indicates that the dried object has received effective and complete steam drying care, and the steam drying care operation needs to be stopped to avoid damage to the dried object caused by over-care.

[0139] Compared with the method of judging whether to stop the steam care operation only based on the relationship between the humidity of the dried object and the humidity threshold, in this embodiment, the temperature change rate is introduced to analyze and judge the stop of the steam drying care operation process, more accurately determining whether to stop / continue the steam drying care operation for the dried object. While ensuring the steam drying care effect of the dried object, it also avoids damage caused by excessive steam drying care operation.

[0140] When the steam generating device is short of water, it will prompt the user to add water, but the whole machine will still operate normally. Once the water shortage is not discovered by the user, it will cause the clothing care to end without achieving the care effect. In the preferred embodiment, the present application fully considers the operability of the dried object care. Once the steam generating device is short of water, the display screen of the whole machine will prompt the user to add water. If the user does not add water in time, the dryer will stop running, and only when water is detected will it execute the normal clothing care process. For details, please refer to Figure 8 , Figure 8 It is a schematic diagram of the water shortage prompt process of the steam generator shown in an exemplary embodiment of the present application. Among them, it at least includes S810 to S870, which are introduced in detail as follows:

[0141] Select the steam drying care program to start, and detect the closed state of the low water level float of the steam generator. When it is detected that the low water level float switch is on and the high water level float switch is off, it indicates that the steam generator is short of water. At this time, the display panel of the dryer will prompt water shortage; after adding water, the icon will disappear. When it is detected that both the low water level float switch and the high water level float switch are on, it means that there is a fault with the float switch, and the dryer panel will prompt F. At this time, maintenance is required; it should be noted that if a non-steam drying care program is selected to start, this fault will not be affected.

[0142] After considering the specification and the disclosed embodiments here, those skilled in the art will easily think of other implementation schemes of the present application. The present application aims to cover any variations, uses, or adaptive changes of the present application, and these variations, uses, or adaptive changes follow the general principles of the present application and include the common general knowledge or conventional technical means in the technical field not disclosed in the present application.

[0143] It should be understood that the present application is not limited to the exact structures described above and shown in the drawings, and various modifications and changes can be made without departing from its scope. The scope of the present application is only limited by the appended claims.
