High-pressure cleaner with multiple working modes

Abstract

The invention relates to a high-pressure cleaner with multiple working modes. The high-pressure cleaner with multiple working modes comprises a main pump and an auxiliary pump which are driven by a main motor and an auxiliary motor respectively; the water outlets of the main pump and the auxiliary pump are connected to a water outlet tee joint through a main pump water outlet check valve and an auxiliary pump water outlet valve respectively; the main motor and the auxiliary motor are powered by a power source controlled by a main switch; the power supply circuit of the main motor is connected in series with a main pump normally-closed pressure switch and an energy saving mode selecting switch; the power supply circuit of the auxiliary motor is connected in series with an auxiliary pump normally-closed pressure switch and an energy saving mode selecting switch; the main pump normally-closed pressure switch and the auxiliary pump normally-closed pressures switch are arranged at the water outlets of the main pump and the auxiliary pump respectively. Through mutual power compensation of the main pump and the auxiliary pump, the high-pressure cleaner with the multiple working modes can maintain the electrical load at a relatively high level when under high pressure and in a high-flow state, thereby being wide in application; the multiple working modes of high pressure, high flow and energy saving can be switched conveniently to meet multiple use demands of users.

Description

technical field [0001] The invention relates to a high-pressure cleaning machine, in particular to a high-pressure cleaning machine with multiple working modes. Background technique [0002] In the high-pressure cleaner industry, especially household electric cleaners, both the pressure and the flow are affected by the motor [0003] However, the power of the motor is mainly limited by the maximum power (maximum current) of household electricity, and the actual cleaning ability and cleaning range cannot be brought into full play. When encountering local dirt that is difficult to clean, it is necessary to use a large Pressure is used to improve the cleaning effect; when encountering easier-to-clean pipes or floors, large flow rates are required to improve cleaning efficiency. In the prior art, in order to obtain high pressure, the motor power is often designed to the maximum allowable power value. When a large flow rate is required, the pressure is reduced and the flow rate ...

AI Technical Summary

Problems solved by technology

In the prior art, in order to obtain high pressure, the motor power is often designed to the maximum allowable power value. When a large flow rate is required, the pressure is reduced and the flow rate is increased through a large-diameter nozzle. Because the motor power will have a large increase with the pressure drop Decrease, the actual flow rise is very limited, can not get a real large flow, the cleaning efficiency of the cleaning machine is limited
