Title:
SPRAYING SYSTEM AND CONTROL METHOD AND APPARATUS THEREFOR, ELECTRONIC DEVICE, AND READABLE STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2023/169385
Kind Code:
A1
Abstract:
A spraying system and a control method and apparatus therefor, an electronic device, a readable storage medium, and an air conditioner. The spraying system comprises a water outlet device (1), a spraying branch (2), a return flow branch (3), and a nozzle (4); a water outlet (11) of the water outlet device (1), the spraying branch (2), and the nozzle (4) are sequentially connected; the spraying branch (2), the return flow branch (3), and a water inlet (12) of the water outlet device (1) are sequentially connected; an electromagnetic valve is disposed in the spraying branch (2) and/or the return flow branch (3), the electromagnetic valve being used to control opening and closing of the spraying branch (2) and/or the return flow branch (3); when the spraying branch (2) is open, liquid flowing out of the water outlet device (1) flows out of the nozzle (4) via the spraying branch (2); and when the return flow branch (3) is open, liquid flowing out of the water outlet device (1) flows into the water outlet device (1) via the return flow branch (3). In this way, implementation of intermittent spraying can be ensured in a spraying system provided with a water pump (5), and water supply pressure can be increased by means of the return flow branch (3), so that the water pump (5) does not need to be frequently started and stopped, and the temperature inside the pump is not increased, thereby ensuring the service life and spraying cooling effect of the system during water-saving operation of the spraying system.
