Spray head, spray cleaning device and kitchen ventilator

Abstract

The invention relates to the field of household appliances and discloses a spray head, a spray cleaning device and a kitchen ventilator. A water-in flow passage (1) and a plurality of water-out flow passages (2) separated out of the water-in flow passage are formed in the spray head (10), the water-out flow passages are in outward flaring shapes and are provided with long and narrow flow passage cross sections, and the minimum cross section area of the water-in flow passage is larger than the sum of all flow passage cross section areas of the multiple water-out flow passages. According to the spray head, the water-out flow passages are set to be in the outward flaring shapes and to be provided with the long and narrow flow passage cross sections, the minimum cross section area of the water-in flow passage is larger than the sum of all the flow passage cross section areas of the multiple water-out flow passages, in this way, the fluid ejected by the spray head can have high scouring force and can also have a large injection area, and it is beneficial to improvement of cleaning efficiency.

Description

technical field [0001] The invention belongs to the field of household appliances, and in particular relates to a spray head, a spray cleaning device and a range hood. Background technique [0002] At present, electrostatic devices are widely used in range hoods for the separation of kitchen oil due to their good oil separation effect and simple implementation. Among them, after the range hood is used for a long time, the oil in the oil fume will accumulate and solidify in a large amount in the electrostatic device, thereby affecting the filtering and separating effect of the electrostatic device on the oil particles. [0003] When the electrostatic device in the range hood needs to be cleaned, the conventional method currently on the market is to use a metal nozzle with several holes. The water column cleans the oil accumulated in the electrostatic device. Although this type of spray cleaning device can spray a water column with a high scouring force, the spray area of ​​t...
