Embodiment Construction

[0019] The kitchen range hood of the present invention is described in detail below with reference to the accompanying drawings:

[0020] Such as Figure 4 As shown, it includes a vertical exhaust duct 100 arranged on the ceiling to discharge indoor air upwards, and a horizontal exhaust duct 110 formed at the bottom of the vertical exhaust duct 100, which is connected as a whole and enlarged, is arranged on the vertical exhaust duct 100 Inside, the exhaust fan 200 that sucks in indoor air and discharges it upwards is formed on the inside of the horizontal exhaust duct 110, and the air supply path 140 that sucks the air in the kitchen to the bottom of the exhaust fan 200 is formed on the discharge side of the air supply path 140. The nozzle part 141 and the curved surface part 142 through which the room air passes through the nozzle part 141 suck the polluted air from the air supply path 140 and supply air to the air supply device 400 . When the polluted air passes through the...

Abstract

The present invention discloses a kitchen ventilator. It includes air-supplying flow passage which is formed in the inner side of horizontal exhaust pipeline, used for sucking kitchen interior air and supplying air towards lower portion of exhaust fan, nozzle portion formed in the exhaust side of air-supplying flow passage, curved surface portion through which the indoor air passed through the nozzle portion can be passed and air-supplying device which is used for sucking pollutant air from air-supplying flow passage and making air-supplying action.

Description

technical field [0001] The invention belongs to a kitchen range hood device, in particular to a kitchen range hood which can improve the suction efficiency of the range hood and reduce the exhaust noise generated from the nozzle part according to the Coanda effect. Background technique [0002] Generally speaking, the kitchen range hood is a device that is installed above the stove to discharge the high-temperature hot air and polluted air generated during cooking; A device that supplies air to the room after being filtered by a filter. If there is an exhaust port in the kitchen, the range hood uses a double-suction cross-flow fan to filter the polluted air generated during cooking through the filter on the bottom of the range hood, and then passes through the straight pipe connected to the outlet of the cross-flow fan to the outside. discharge. If there is no exhaust port in the kitchen, the range hood is re-supplied to the kitchen after the air sucked by the cross-flow f...
