The embodiment of the present invention provides an electronically controlled dryer and its control method. The electronically controlled dryer includes a drying tank and a first check valve. One end of the drying tank is connected to the air inlet, and the other end of the drying tank passes through the first check valve The direction valve is connected with the gas outlet; the electric control dryer also includes a controller, a solenoid valve connected with the controller, and an unloading valve connected with the exhaust port, the first end of the solenoid valve is connected with the first one-way valve and the gas outlet The second end of the solenoid valve is connected to the unloading valve, and the third end of the solenoid valve is connected to the exhaust port; the electric control dryer also includes a second one-way valve and a throttle valve, and the second one-way valve One end of the valve is connected to the pipeline between the solenoid valve and the unloading valve, the other end of the second check valve is connected to the pipeline between the drying tank and the first check valve through a throttle valve, and the other end of the drying tank is connected to the pipeline between the unloading valve. Loading valve connection realizes the optimization of the electronically controlled dryer. A solenoid valve can be used to realize unloading and regeneration backflushing at the same time, reducing the cost of the electronically controlled dryer.
Description
technical field [0001] The invention relates to the field of dryers, in particular to an electrically controlled dryer and a control method thereof. Background technique [0002] With the development of automobile electrification technology, electric air compressors are used to supply air to the brake system in automobiles, and electric air compressors need to be equipped with electronically controlled dryers to cooperate with them. [0003] In the prior art, the electronically controlled dryer usually uses a solenoid valve to realize the functions of unloading, reverse regeneration and blowing again, but the existing electronically controlled dryer has a complex structure and high cost. Contents of the invention [0004] In view of the above problems, it is proposed to provide an electronically controlled dryer and its control method to overcome the above problems or at least partially solve the above problems, including: [0005] An electronically controlled dryer, whic...
