Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of clothes drying, and specifically provides a control method of a clothes dryer and the clothes dryer. BACKGROUND

[0002] The clothes dryer is a cleaning household appliance that uses electric heating to evaporate and dry the moisture in washed clothes. With the improvement of lifestyle, the demand for clothes dryers gradually increases.

[0003] At present, the clothes dryer usually adopts the mode of air inlet at the bottom of the drum. When a large amount of clothes is put into the clothes dryer, a part of the hot air will rush to the inner wall of the drum along the existing inertia after entering the drum, which causes the clothes in the central part of the drum to be often not dried.

[0004] In addition, the existing clothes dryer can only adjust the drying time and the drying air volume to meet the drying needs of different types of clothes when drying different types of clothes.

In addition, ordinal numbers such as "first", "second", etc. are only for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0069] In addition, it should also be noted that in the description of the present application, unless otherwise explicitly specified and limited, the terms "mounting", "connection" should be understood broadly, for example, it can be fixed connection, or detachable connection or integral connection; it can be mechanical connection, or electrical connection; it can be direct connection, or indirect connection through intermediate medium. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0070] As Figure 1 illustrated, the present application proposes a control method of a clothes dryer, the clothes dryer comprising a drum provided with a central air duct and a side air duct, the control method comprising the following steps:

[0071] Step G1: obtaining the type of clothes;

[0072] Step G2: determining whether the clothes are wool and silk fabrics;

[0073] Step G3: selectively adopting a first drying mode or a second drying mode to dry the clothes according to the determination result.

[0074] Further, as Figure 2 illustrated: Step G31: when the clothes are wool and silk fabrics, the first drying mode is adopted to dry the clothes;

[0075] Step G32: when the clothes are non-wool and silk fabrics, the second drying mode is adopted to dry the clothes;

[0076] Among them, the first drying mode includes two stages: a stage of simultaneously opening the central air duct and the side air duct, and a stage of only opening the side air duct; the second drying mode includes three stages: a stage of only opening the central air duct, a stage of simultaneously opening the central air duct and the side air duct, and a stage of only opening the central air duct.

[0077] In this embodiment, after obtaining the type of clothes, the first drying mode or the second drying mode is selected according to whether the clothes are wool and silk fabrics. Since wool and silk fabrics are soft and relatively light, only the side air duct is opened in the later stage of drying, which can continue to dry and avoid the clothes being blown by the wind of the central air duct. The weight of non-wool and silk fabrics is relatively large, especially when a large amount of non-wool and silk fabrics need to be dried, the hot air sent by the central air duct is undoubtedly the most important, therefore, the central air duct is opened in three stages, in addition, in order to avoid the clothes in the central part of the drum from being not dried, the side air duct is opened in the second stage of the second drying mode, and since the opening time of the side air duct is less than that of the central air duct, the relationship between the air volume of the side air duct and the air volume of the central air duct is adjusted to maximize the drying efficiency and shorten the drying time.

[0078] The side air duct in the present application is located between the inner wall and the outer wall of the drum, the air outlets of the side air duct are multiple and are arranged on the inner wall of the drum in a uniform manner, and the air outlets of the side air duct are directed towards the rotation axis of the drum.

[0079] Further, as Figure 3 illustrated, the first drying mode comprises the following steps:

[0080] Step M10, simultaneously opening the central air duct and the side air duct;

[0081] Step M20, after T1 time period, close the center air duct, only open the side air duct;

[0082] Step M30, after T2 time period, close the side air duct;

[0083] Step M40, determine whether the clothes in the drum are dry, if not, return to step M10; if yes, the dryer stops working.

[0084] In this embodiment, since the weight of wool silk fabric is relatively small and the texture is soft, in order to avoid wrinkles or deformation during drying, a clothes holder needs to be put in during drying, one end of the clothes holder is connected to the drum shaft, and the other end is connected to the shell of the dryer. During the rotation of the drum, the clothes holder will not rotate, so the wool silk fabric will not rotate, thereby avoiding wrinkles or deformation of the wool silk fabric due to its own extrusion; in the later stage of drying, the weight of the clothes is further reduced after dehydration, in order to avoid the clothes being blown away from the clothes holder, therefore, the center air duct needs to be closed and only the side air duct is retained for drying. Since the air provided by the side air duct is in a roughly symmetrical form, the force of the hot air acting on the clothes can cancel out most of each other, which improves the stability of the clothes during drying.

[0085] Further, when the center air duct and the side air duct are opened at the same time, the air volume of the side air duct is 1.5-2 times that of the center air duct.

[0086] Further, as shown in FIG. 2, the second drying mode includes the following steps: Figure 4

[0087] Step S10, when drying starts, open the center air duct and close the side air duct;

[0088] Step S20, after T3 time period, open the side air duct;

[0089] Step S30, after T4 time period, increase the air volume of the side air duct;

[0090] Step S40, after T5 time period, close the side air duct and only open the center air duct, the air volume of the center air duct remains the same as that of the center air duct in step S30;

[0091] Step S50, after T6 time period, close the center air duct;

[0092] Step S60, determine whether the clothes in the drum are dry, if not, return to step S20; if yes, the dryer stops running.

[0093] ​In the second stage of drying in the embodiment, the side air duct is not only opened at the same time as the center air duct, but also the air volume of the side air duct and the air volume of the center air duct are adjusted in different proportions in two different time periods. The adjustment of the air volume ratio not only improves the drying efficiency, but also reduces the over-drying of the clothes, avoids the wrinkles or deformation of the clothes, and improves the user experience.

[0094] Further, in step S20, the air volume of the side air duct is 0.5-1 times the air volume of the center air duct; and / or

[0095] In step S30, the air volume of the side air duct is 1.5-2 times the air volume of the center air duct.

[0096] Further, T1 is 5-10 min, and T2 is 5-20 min.

[0097] In the embodiment, T1 and T2 are optimized according to the characteristics of wool and silk fabrics, actual operation experience and research and development requirements, and T1 is 5-10 min and T2 is 5-20 min.

[0098] Further, when the height of the wool and silk fabric does not exceed the radius of the drum, T1 is 5-7 min and T2 is 5-10 min; when the height of the wool and silk fabric exceeds the radius of the drum, T1 is 7-10 min and T2 is 10-20 min.

[0099] In the embodiment, the drying time period is adjusted according to the amount of clothes to be dried, so as to improve the drying efficiency, avoid waste of energy, and also avoid wrinkles or deformation of the clothes due to over-drying.

[0100] Further, T3 is 2-50 min, T4 is 2-10 min, T5 is 2-10 min, and T6 is 1-10 min.

[0101] In the embodiment, since other clothes do not have the softness of wool and silk fabrics, they are usually dried in a large amount and mixed with various fabrics. In order to ensure the drying effect of the clothes and also avoid wrinkles or deformation of the clothes, the time periods involved in each stage are optimized, and the optimized time periods are: T3 is 2-50 min, T4 is 2-10 min, T5 is 2-10 min, and T6 is 1-10 min.

[0102] Further, when the space occupied by the non-wool silk fabric in the drum is less than 50%, T3 is 2-20 min, T4 is 2-5 min, T5 is 2-5 min, and T6 is 1-5 min; when the space occupied by the non-wool silk fabric in the drum is more than 50%, T3 is 20-50 min, T4 is 5-10 min, T5 is 5-10 min, and T6 is 5-10 min.

[0103] In the embodiment, different time periods are determined according to the amount of clothes to be dried in the drum, which not only improves the drying efficiency, but also improves the experience of the customer.

[0104] The application also provides a clothes dryer, comprising a controller, the clothes dryer is any one of the clothes dryer described in the above, and the controller can execute the control method described in any one of the above.
