Embodiment 1

[0054] like Figures 1 to 2 As shown, a method for detecting clogging of a clothes dryer filter screen includes the steps of:

[0055] S1, the dryer starts to run;

[0056] S2, obtain the continuous running time y of the clothes dryer at regular intervals;

[0057] S3, judging whether the continuous running time y of the dryer satisfies the first preset condition; if so, continue to perform step S4, if not, then the dryer is running normally, and continue to perform step S2;

[0058] S4, obtain the current refrigerant temperature tcomp at the inlet of the condenser and the current refrigerant temperature tcond at the outlet of the condenser;

[0059] S5, calculate the value of the current tcomp-tcond;

[0060] S6, determine whether the current value of tcomp-tcond satisfies the second preset condition; if so, the dryer suspends operation to remind the user to clean the filter screen; if not, the dryer runs normally, and proceeds to step S2.

[0061] Wherein, the first pres...

Embodiment 2

[0075] like image 3 As shown, a method for detecting clogging of a clothes dryer filter screen includes the steps of:

[0076] S1, the dryer starts to run;

[0077] S2, obtain the refrigerant temperature tcond at the condenser outlet of the dryer at regular intervals;

[0078] S3, judging whether the temperature tcond of the refrigerant at the outlet of the condenser satisfies the third preset condition; if so, continue to perform step S4, if not, the clothes dryer is running normally, and continue to perform step S2;

[0079] S4, obtain the current refrigerant temperature tcomp at the inlet of the condenser and the current refrigerant temperature tcond at the outlet of the condenser;

[0080] S5, calculate the value of the current tcomp-tcond;

[0081] S6, determine whether the current value of tcomp-tcond satisfies the second preset condition; if so, the dryer suspends operation to remind the user to clean the filter screen; if not, the dryer runs normally, and proceeds ...

Embodiment 3

[0088] like Figures 4 to 5 As shown, a method for detecting clogging of a clothes dryer filter screen includes the steps of:

[0089] S1, the dryer starts to run;

[0090] S2, obtain the condenser outlet refrigerant temperature tcond of the dryer and the continuous running time y of the dryer at regular intervals;

[0091] S3, judging whether the continuous running time y of the dryer satisfies the first preset condition; if so, continue to perform step S4, if not, continue to judge whether the condenser outlet temperature tcond satisfies the third preset condition; If yes, continue to step S4, if not, the clothes dryer is running normally, and continue to execute step S2;

[0092] S4, obtain the current refrigerant temperature tcomp at the inlet of the condenser and the current refrigerant temperature tcond at the outlet of the condenser;

[0093] S5, calculate the value of the current tcomp-tcond;

[0094] S6, judging whether the current value of tcomp-tcond satisfies t...

Abstract

The invention provides a method for detecting clogging of a filter screen of a clothes dryer and a clothes dryer, comprising steps: S1, the clothes dryer starts to run; S2, the temperature tcond of the refrigerant at the outlet of the condenser is obtained every certain time and the clothes dryer runs continuously. Time y; S3, determine whether the y meets the first preset condition; and / or, whether the tcond meets the third preset condition; if so, continue to perform steps S4; S4, obtain the current refrigerant temperature at the inlet of the condenser tcomp and the current refrigerant temperature tcond at the outlet of the condenser; S5, calculate the value of the current tcomp-tcond; S6, determine whether the current value of tcomp-tcond satisfies the second preset condition; if so, the dryer suspends operation and reminds the user to clean The filter screen; the method for detecting clogging of the filter screen of the clothes dryer and the clothes dryer of the present invention have the advantages of simple detection method, high accuracy and good real-time performance.

Description

technical field [0001] The invention relates to a clothes dryer and a method for controlling the clothes dryer, in particular to a method for detecting clogging of a filter screen of a clothes dryer and a clothes dryer. Background technique [0002] Existing clothes dryers, such as heat pump clothes dryers, are usually provided with the following air circulation channels: the hot air heated by the condenser is sent into the drum containing the clothes through the rear air channel, and the moisture is taken from the clothes. The humid air is sent back to the evaporator for dehumidification, and the dehumidified dry air is heated by the condenser again and sent into the drum. At the same time, in order to circulate the heating and drying of the air, the heat pump dryer is also provided with the following refrigerant circulation channels: the refrigerant gas with high temperature and high pressure enters the condenser from the inlet of the condenser, and exchanges heat with the...
