Mounting and fixing; and (3) testing the pressure of the door pocket fresh air pipeline 33, debugging equipment, and installing and delivering the kitchen door pocket line 22.
Example 2
As shown in fig. 2 to 10, in the present embodiment, the fresh air fan 6 is respectively disposed in the vertical air transmission pipe 323 and the L-shaped embedded wall air pipe 331. The kitchen ventilator linkage line is simultaneously connected with the vertical air transmission pipe 323 and the fresh air fan 6 in the L-shaped embedded wall air pipe 331. Other structures and construction methods are the same as those of embodiment 1, and are not described in detail here.
In this embodiment, fresh air in the kitchen enters the room through the rain-proof air valve 312 in the outer wall and the air pipe of the outer wall sealing sleeve 311, is filtered by the air filtering device 341, is divided into two paths through the fresh air pipeline, and is respectively conveyed to the range hood fresh air pipeline 32 and the door pocket fresh air pipeline 33.
The first path is as follows: fresh air of the range hood:
fresh air of the range hood enters: fresh air in the fresh air pipeline is pressurized by a fresh air fan 6 arranged in a fresh air pipeline 32 of the range hood, is conveyed to a fresh air distributing pipe 12 through a fresh air inclined pipe 13, is sprayed to the outside of the range hood 1 through a hole-shaped netted air port 14 formed in the outer wall of the fresh air distributing pipe 12 and the outer shell of the range hood at the same time, and forms an umbrella-shaped fresh air wall around the bottom frame of the range hood 1.
Fresh air exhaust of the range hood: the fresh air fan 6 and the exhaust fan of the range hood are set to be started and stopped simultaneously, when the range hood discharges smoke, fresh air is fed simultaneously, air of a fresh air wall passes through the exhaust suction inlet of the range hood, passes through the exhaust fan, enters the exhaust pipe 16, passes through the exhaust check valve 165 and the exhaust transverse pipe 163, enters the kitchen flue 164, passes through the kitchen flue 164 of a building, and is discharged outdoors.
The airflow state below the smoke collecting hood of the range hood is as follows: under the simultaneous action of the suction airflow formed by smoke exhaust of the range hood and the umbrella-shaped fresh air wall formed by fresh air, small-range wrapped air flow is formed at the bottom edge of the smoke collecting hood of the range hood, and the oil smoke formed by cooking enters a smoke exhaust suction inlet of the range hood after being wrapped by the airflow and is exhausted outdoors through a smoke exhaust system.
Hole-type net air opening 14 of range hood: considering human body feeling comfort level and fresh air wall effect and the interference degree to stir-fry processing, synthesizing these three factors, the netted wind gap air-out direction of pass arranges that three direction is optional, and air-out is upwards gone out promptly, goes up the air-out to the slant, and the air-out is down to the slant.
And a second path: fresh air of the door pocket:
fresh air of the door pocket enters: fresh air in the fresh air pipeline is conveyed to the door pocket fresh air pipeline 33 through the air inlet pipe 31, the built-in fresh air fan 6 is installed in the L-shaped embedded wall air pipe 331, the door pocket fresh air pipe sleeve 332 and the conversion box 4 connected with the L-shaped embedded wall air pipe 331 are pressurized by the fresh air fan 6, the fresh air enters the door pocket built-in frame type air distribution pipe through the conversion box 4, namely the door pocket fresh air pipe sleeve 332, and is sprayed to the outside of the door pocket through hole type mesh air openings which are simultaneously formed in the outer wall of the door pocket fresh air pipe sleeve 332 and a door pocket wedge plate, so that a fresh air wall is formed around the door pocket frame.
And (3) discharging fresh air of the door pocket: the built-in fresh air fan 6 and the range hood exhaust fan which are installed in the L-shaped embedded wall air pipe 331 are set to be started and stopped simultaneously under the working state, when the range hood exhausts smoke, fresh air of the door pocket is sent simultaneously, air of the fresh air wall flows to the exhaust suction inlet of the range hood through the kitchen room, flows into the exhaust pipe 16 through the range hood exhaust fan, enters the kitchen flue 164 through the exhaust check valve 165 and the transverse exhaust pipe 163, and is exhausted out of the room through the kitchen flue 164 of the building.
Airflow state of door pocket new trend: under the simultaneous action of the suction air flow formed by smoke discharge of the range hood and the fresh air wall formed by fresh air of the door pocket, air flow is blocked by the door pocket, a great amount of oil smoke formed by cooking is sucked away by the range hood, and part of the oil smoke overflows, is blocked by the air flow and is brought into a smoke discharge suction inlet of the range hood, and is discharged out of a room through a smoke discharge system, so that the oil smoke is prevented from entering other rooms outside a kitchen, and the life quality of a house is improved.
The above-mentioned embodiments are only given for the purpose of more clearly illustrating the technical solutions of the present invention, and are not meant to be limiting, and variations of the technical solutions of the present invention by those skilled in the art based on the common general knowledge in the art are also within the scope of the present invention.
