Cleaning control method and system of heat exchanger for clothes dryer and clothes dryer

Abstract

The invention discloses a cleaning control method and system of a heat exchanger for a clothes dryer and the clothes dryer. The cleaning control system of the heat exchanger comprises a water collector for collecting condensate water, a water storage tank, a water spray head and a pump body, wherein the water spray head is provided with three water nozzles and two water through holes; and a control valve is arranged between each water through hole and the water storage tank and used for controlling the connection/separation between the corresponding water through hole and the water storage tank. The cleaning control method comprises the following steps: detecting the cleanliness of three-section parts of the heat exchanger, wherein the three-section parts of the heat exchanger include a left part, a middle part and a right part; judging the cleanliness of the three-section parts to obtain judgment results; and controlling the control valves according to the judgment results to correspondingly clean the left part, middle part and right part of the heat exchanger through the three water nozzles respectively. In the invention, the effluent of corresponding water nozzles is controlled by detecting the cleanliness of the three-section parts of the heat exchanger; the left part, middle part and right part of the heat exchanger are cleaned respectively; and the cleaning effect is good, and useless cleaning is avoided.

Description

technical field [0001] The present invention relates to the technical field of clothes dryers, and more specifically, to a cleaning control method for heat exchangers used in clothes dryers, a cleaning control system for heat exchangers used in clothes dryers, and a clothes dryer with the cleaning control system machine. Background technique [0002] In the cleaning device of the heat exchanger in the related art, the water outlet of the water nozzle is controlled through a straight-through valve, thereby using the condensed water in the water tank to clean the surface of the heat exchanger. However, the control of this water outlet method is not sensitive, and the flushing The strength is not strong enough to clean the dander on the surface of the heat exchanger, and the water sprayed from the nozzle is uneven, which seriously affects the heat exchange effect of the heat exchanger. [0003] Moreover, the distribution of lint at the boundary of the heat exchanger is not uni...
