Description

Technical Field

[0001] The utility model relates to the field of buildings, and particularly to an indoor ventilation system for a building. Background Art

[0002] Ventilation, also known as air exchange, is the use of mechanical or natural methods to deliver sufficient fresh air into the indoor space, while expelling the dirty air that does not meet the hygiene requirements in the room, so that the indoor air meets the hygiene requirements and the needs of the production process.

[0003] The existing ventilation system uses a blower to transport outside air into the room for ventilation. When it rains heavily, rainwater will enter the air duct through the air inlet and accumulate in the air duct. After a long time, a musty smell will be generated in the air duct. Unless the air duct outlet is closed, ventilation will be impossible.

[0004] In summary, in order to solve the deficiencies in the prior art, it is necessary to design a building indoor ventilation system with a simple structure. Utility Model Content

[0005] The utility model provides a building indoor ventilation system to solve the problems of the prior art.

[0006] The purpose of the utility model can be achieved through the following technical solutions: a building indoor ventilation system comprises: an air duct, an air inlet pipe, an adjustment component and a fan, the air inlet pipe is fixedly connected to the left side of the air duct, and the right side of the air duct is connected to the indoor, the adjustment component comprises a frame, a motor, a fixed baffle and a rotating baffle, the frame is fixed in the air duct, the motor is arranged on the frame, the fixed baffle is fixed to the end face of the air inlet pipe, the fixed baffle and the end face of the air inlet pipe are provided with air inlet holes, the rotating baffle is connected to the motor through a rotating shaft, the rotating baffle closes the air inlet hole when driven by the motor, the lower end of the air inlet pipe is vertically connected to a vertical air inlet pipe, and the fan is arranged in the air duct.

[0007] As a further improvement, the diameter of the air inlet duct opening is increased toward the left side, and the diameter of the vertical air inlet duct opening is increased toward the bottom side.

[0008] As a further improvement, a groove is provided on the right side of the air duct, a filter is provided in the groove, a threaded groove is provided on the right side of the groove, a fixing piece is threadedly connected in the threaded groove, and a channel connected to the air duct is provided in the middle of the fixing piece.

[0009] As a further improvement, a limiting protrusion is provided in the groove, and a clamping groove which is clamped with the limiting protrusion is provided on the filter net.

[0010] Compared with the prior art, the beneficial effects of the building indoor ventilation system of the utility model are:

[0011] When ventilation is needed on sunny days, the motor drives the rotating baffle to rotate a certain angle and then overlap with the fixed baffle. The natural wind from the outside is sucked into the air duct through the air inlet by the fan, and then enters the room from the right side of the air duct. When ventilation is needed on rainy days, the motor drives the rotating baffle to rotate a certain angle and then overlap with the fixed baffle. The rotating baffle closes the air inlet, and air is sucked into the fan from the vertical air inlet duct at the lower end. The vertical setting of the vertical air inlet duct can prevent rainwater from entering the air duct, preventing rainwater from accumulating in the air duct to produce musty odor.

[0012] By means of the fixed baffle and the rotating baffle on the air inlet duct, and in conjunction with the vertical air inlet duct at the lower end, different air inlet channels can be flexibly selected according to actual weather conditions to ensure ventilation at all times.
