Control apparatus for solenoid pump of instant heating steam cleaner

Abstract

The invention discloses a control apparatus for a solenoid pump of an instant heating steam cleaner, which comprises a solenoid pump for conveying the water stored in a water tank to a steam generator, a pump-driving part for driving the solenoid pump with the common alternating current, a zero point detecting part for detecting each zero point of the common alternating current, a frequency control part for controlling the frequency of the pump-driving part into which the half-period power supply of the alternating current source is input based on the detection result of the zero point detecting part, and a dc source generation part for generating a predetermined dc source from the common alternating current source and supplying the same for each part of the apparatus. The invention solves the problem in the prior art, and provides a control apparatus for a solenoid pump of an instant heating steam cleaner, which makes the solenoid pump maintain the appropriate pressure to the steam generator and can supply the expected water amount.

Description

technical field [0001] The invention relates to an electromagnetic pump control device of an instant heating steam cleaner. Background technique [0002] The working principle of the instantaneous heating steam cleaner is: through the steam generator formed by the tubular flow path and the heater arranged around the tubular flow path, steam is sprayed to the surface to be cleaned to achieve the purpose of cleaning. After the electromagnetic pump is started, the instantaneous heating steam cleaner will output the water stored in the water tank to the steam generator by the electromagnetic pump, so that the output water will be heated by the heater during the process of passing through the flow path of the steam generator. Finally, it is ejected in the form of steam. [0003] attached figure 1 It is the sectional view of the electromagnetic pump of the instantaneous heating type steam cleaner under the prior art, as attached figure 1 As shown, in the past, the electromagnet...

Problems solved by technology

[0005] However, according to the electromagnetic pump control method of the instantaneous heating steam cleaner in the prior art, when the steam generator is in the starting state, the voltage of each cycle of the input common AC power is obviously lower than the maximum voltage of the common AC power, Due to the steam pressure generated in the heater of the steam generator, there may be a reverse flow of water output by the electromagnetic pump
