However, foreign matter such as lint contained in laundry may be mixed in the air discharged from the drum, and such foreign matter may adhere to the surface of the evaporator or condenser, thus becoming an obstacle to lowering the heat exchange efficiency between the air and the refrigerant. reason
[0005] In order to avoid this situation, in the related art, the lint removal filter can be arranged on the upstream side of the evaporator to minimize the adhesion of lint particles to the surface of the evaporator, but in reducing the lint removal filter There are limitations in terms of mesh size
As a result, it would still be impossible to remove lint particles having a size smaller than the mesh size, and thus it would not be possible to avoid the adhesion of lint particles to the surface of the evaporator when the filter is used for a long time
In addition, foreign matter filtered through the lint removal filter can remain on the surface of the lint removal filter, thereby making this a cause of obstructed air flow

The present invention relates to a diagnostic method for a clothes treating apparatus, and according to an embodiment of the present invention, provided is a diagnostic method of the clothes treating apparatus having a compressor, a condenser, an expansion apparatus, and an evaporator for cooling air being discharged from a drum by the evaporator of a heat pump, and the method may include activating the compressor; measuring a property (P1) of the refrigerant that has passed through the compressor; re-measuring a property (P2) of the refrigerant that has passed through the compressor after a predetermined period of time; checking whether or not a value F defined as P2-P1 is equal to or greater than a predetermined value; suspending the operation of the compressor and repeating the foregoing processes when the value F is less than the predetermined value; and determining that a failure has occurred in the clothes treating apparatus when the execution number of the processes is equal to or greater than the predetermined value.
Description
technical field [0001] The present invention relates to a diagnosis method of a laundry treatment device. Background technique [0002] A laundry treating device having a drying function, such as a dryer, may generally supply hot air to a drum to remove moisture in a state in which drying objects are loaded in the rotating drum. The hot air supplied to the drum is generated by applying heat obtained by combustion of fuel such as resistance heating, gas, etc. to the air supplied to the drum, but a heat pump may be used for hot air generation to reduce energy consumption. [0003] More specifically, high temperature air discharged from the drum may be cooled and compressed by heat exchange with the evaporator, and air supplied to the drum may be heat exchanged with the condenser to generate hot air. When using a heat pump, the heat wasted in the discharge or compression process can be re-used to generate hot air, thereby reducing energy consumption to that extent. [0004] A...
