Water pump device for electric appliances

Abstract

A water pump device for electric appliances includes a water container, a piston cylinder, and an AC synchronous motor. The piston cylinder includes a piston. The AC synchronous motor drives the piston to reciprocate. The water container supplies water through reciprocation of the piston driven by the AC synchronous motor. The water in the water container enters the piston cylinder for pressurization. The pressurized water enters a heating member of a steam generator to output high temperature and high pressure steam. The water pump device further includes a steam adjustment knob between the clockwise check valve and the piston cylinder. The steam adjustment knob can be turned to drive a cam which is used to change the movement route of the piston, so that the volume of the pressurized water can be adjusted for desired high temperature and high pressure steam.

Description

BACKGROUND OF THE INVENTION[0001](a) Field of the Invention[0002]The present invention relates to a water pump device for electric appliances, and more particularly to one having an AC synchronous motor adapted for domestic or industrial electric appliances, such as a portable steam cleaner, a steam mop, a steam mop cooperated with a vacuum cleaner, or the like.[0003](b) Description of the Prior Art[0004]Domestic or industrial electric appliances, such as a portable steam cleaner, a steam mop, a steam mop cooperated with a vacuum cleaner or the like, adopts the following three ways to pour water into a heating member of a steam generator.[0005]The first way is that the inputted alternating current is rectified through a transformer and the voltage is lowered and stabilized by other electronic components on the circuit board, so that the required voltage and current are inputted to a DC motor for driving a pair of deceleration gears to drive a piston cylinder. Thus, the water in the ...

AI Technical Summary

Benefits of technology

The invention is a water pump device that uses an AC synchronous motor to drive a piston, which then pressurizes water in a container. The water is then heated by a steam generator to create high-temperature, high-pressure steam. The invention is different from previous designs because it does not require electronic components or deceleration gear boxes, which can lead to limescale buildup and other obstacles. The AC synchronous motor is a safe and stable motor that can be easily obtained. It has a rotation speed that is appropriate for driving the piston. The motor can be directed in either a clockwise or counterclockwise direction, and it will change its rotation direction in response to a counter pressure, preventing blockages and accidents. This design ensures the motor is always running at its best, even under high-temperature conditions.

Problems solved by technology

The drawback of this pump device is that the alternating current of the power supply must be transformed into direct current.

This increases the cost and difficulty for assembly, and is not compact.

In this way, it must use complicated and expensive electronic components and circuit to change the voltage of the DC motor so as to change the rotation speed of the DC motor for adjustment of the temperature and volume of the outputted steam.

The electromagnetic pump is expensive and large in size.

The limescale is easy to block the inlet and outlet of the electromagnetic pump, which may result in malfunction of the steam electronic appliance.

In this way, it must use complicated and expensive electronic components and circuit to change the voltage of the electromagnetic pump so as to change the reciprocation speed of the pillar piston in the electromagnetic pump for adjustment of the temperature and volume of the outputted steam.

This way cannot output high temperature and high pressure steam.

There is no pump in the system, so it cannot adjust the temperature and volume of the outputted steam.
