Embodiment 1

[0045] Such as figure 1 , as shown in 3-10, a fresh air system built in the range hood and the door cover of the present invention includes a kitchen range hood 1, a kitchen door cover 2 and a fresh air duct 3, and a fresh air fan 6 is arranged in the fresh air duct 3. The fresh air duct 3 includes an air inlet pipe 31 , a range hood fresh air duct 32 and a door pocket fresh air duct 33 . In this example, if figure 1 As shown, the fresh air fan 6 is only arranged in the air inlet pipe 31 . One end of the air inlet pipe 31 is provided with an outer wall airtight casing 311 and a rainproof and ventilating valve 312 sequentially from the inside to the outside, and the other end is connected with the fresh air duct 32 of the range hood and the fresh air duct 33 of the door pocket through the fresh air tee 34 respectively. An air filter device 341 is also arranged on the fresh air tee 34 connected to the air inlet pipe 31 . The range hood fresh air duct 32 is composed of a horiz...

Embodiment 2

[0071] Such as Figure 2-10 As shown, in this embodiment, the fresh air fan 6 is respectively arranged in the vertical air duct 323 and the L-shaped embedded wall air duct 331 . The kitchen range hood linkage line is connected to the above-mentioned vertical air duct 323 and the fresh air fan 6 in the L-shaped pre-embedded wall air duct 331 at the same time. Other structures and construction methods are the same as in Embodiment 1, and will not be described in detail here.

[0072]In this embodiment, the fresh air from the kitchen enters the room through the rain-proof and ventilating valve 312 inside the outer wall, and the air duct of the airtight casing 311 on the outer wall enters the room, is filtered by the air filter device 341, and is divided into two paths through the fresh air pipe, and is sent to the fresh air of the range hood respectively. Duct 32 and door casing fresh air duct 33.

Abstract

The invention relates to a construction method of a fresh air system built inside a range hood and on a door cover, and belongs to the technical field of fresh air system construction technology. The fresh air system includes the kitchen range hood, the kitchen door cover and the fresh air duct. The fresh air duct is equipped with a fresh air fan. The fresh air duct includes the air inlet pipe, the range hood fresh air duct and the door cover fresh air duct; Air duct and door cover fresh air duct cover; the kitchen range hood includes the range hood shell and the fresh air distribution duct on the inner and outer edges; the method includes the following steps: the structure pre-embedded stage; the factory processing stage, including kitchen range hood processing, kitchen door cover Processing; equipment installation and commissioning delivery; and installation and fixing. The range hood of the invention has good smoke exhaust effect, sufficient supply of fresh air, no bad smell in the room, and short construction period.

Description

technical field [0001] The invention relates to a construction method of a fresh air system, in particular to a construction method of a fresh air system built inside a range hood and on a door cover, and belongs to the technical field of fresh air system construction technology. Background technique [0002] With the development of science and technology, building doors and windows are gradually updated, their performance is steadily increasing, their airtightness performance is gradually improving, and the infiltration of cold wind is gradually decreasing. The large air volume in the range hood market has become a hot spot. [0003] The existing range hood does not have a fresh air device. When the range hood is turned on to exhaust smoke, due to the high air tightness of the building, the small pores of the doors and windows of the building, the infiltration of outdoor air is insufficient, the air flow replenishment is less than the design value of the hood air volume, t...
