Title:
HIGH-PRESSURE CLEANING MACHINE USING BOTH ALTERNATING CURRENT AND DIRECT CURRENT
Document Type and Number:
WIPO Patent Application WO/2023/092664
Kind Code:
A1
Abstract:
The present invention relates to a high-pressure cleaning machine using both an alternating current and a direct current. The high-pressure cleaning machine comprises: an alternating-current channel, an input end of which is connected to an alternating-current power supply, and an output end of which is connected to an alternating-current electric motor; a direct-current channel, an input end of which is connected to a battery pack, and an output end of which is connected to the direct-current electric motor; and a charging channel, an input end of which is connected to the alternating-current power supply, and an output end of which is connected to the battery pack. The alternating-current electric motor and the direct-current electric motor share a high-pressure pump, and an output end of the high-pressure pump is connected to a high-pressure pipe, a high-pressure gun and a nozzle. The beneficial effects of the present invention are that, if there is alternating-current mains electricity, a cleaning machine can be driven by using an alternating-current power source, and the alternating-current mains electricity can also charge a battery pack after being rectified and transformed by means of a charging channel, such that charging can be performed during use, thereby improving convenience; if there is no alternating-current mains electricity, the cleaning machine can be driven by the battery pack, so as to get rid of the constraint of an electric wire, thereby greatly increasing the usage places of the cleaning machine and greatly expanding the usage range thereof, and meeting more usage requirements; and it is possible to select only one of an alternating-current mode or a direct-current mode for operation, and it is also possible to operate under an alternating current and a direct current at the same time.
