Embodiment Construction

[0033] The following will describe in detail with reference to the drawings and embodiments, and the embodiments in the present application and the features in the embodiments can be combined without conflict.

[0034] figure 1 For a side view of a clothes dryer, such as figure 1 As shown, the clothes dryer 1 has a cabinet 2, an inner tub 5 located in the cabinet 2 and driven by a main motor 4 to rotate, and an outer tub 6 (ie, a drying tub) set outside the inner tub 5 . The outer tub 6 is connected to the air channel 9 of the condensing device 7 and communicated in space. The air channel 9 of the condensing device further connects the fan 11 and the air heating channel 10 in sequence. The other end of the air heating channel 10 is then in spatial communication with the tub 6 .

[0035] In the drying process, the heater 12 (heating device) in the air heating channel 10 heats the drying air 8 flowing through it; the heated high-temperature drying air 8 enters the inner barre...

Abstract

The invention discloses a clothes dryer and a fault self-diagnosing method. The clothes dryer at least comprises the following components of a drying barrel, a fan promoting air flow to move, a heating device heating air, a sensor detecting air temperature of the drying barrel and a control device. The method comprises steps of a heating procedure including starting the heating device and the fan, and detecting heating time (t1) required for heating a temperature value of the sensor to a preset temperature value (T), a cooling procedure including closing the heating device, and detecting cooling time (t2) required for heating a temperature value of the sensor to a preset temperature value (T0), and comparing the heating time (t1) and the cooling time (t2) with a standard value to determine a corresponding fault component. By the use of the fault self-diagnosing method, a problem of inconvenient maintenance due to incapability of fault self-detection of clothes driers in the prior art can be solved, so on one hand, a user can make primary judgment whether to call for after-sale support according to a self-diagnosing result of the clothes dryer, and on the other hand, the self-diagnosing result of the clothes dryer can work as reference for after-sale supporting work.

Description

【Technical field】 [0001] The invention relates to a machine capable of drying clothes, in particular to a fault self-checking method of the machine. 【Background technique】 [0002] Clothes dryers generally include machines with pure dryer functions as well as machines that combine washing and drying functions. The drying principle of the clothes dryer can be roughly summarized as follows: under the action of the heating device, the dry air is heated by the heating device to form dry hot air, and then enters the drying barrel to exchange heat with the wet clothes, and the clothes in the clothes The moisture is taken away to form relatively humid hot air, which is then condensed by the condensing device, and the moisture in it is condensed into water, and then discharged through the drain pipe, and the condensed air becomes relatively dry cold air , under the action of the fan, it is redirected to the heating device, and the heated and dried hot air enters the next cycle, and...
