Passive ventilation device for resident house

Abstract

The invention relates to the technical field of house ventilation, and discloses a resident house passive ventilation device which comprises a shell, a sleeve and two air catching covers, bent pipes are fixedly connected in the two air catching covers, the side wall of the shell is fixedly connected with the pipe walls of the bent pipes through mounting openings, the lower end of the shell is connected with the upper end of the sleeve in a sleeving mode through a round opening, and the upper end of the sleeve is fixedly connected with the lower end of the shell. An air guide mechanism is connected into the bent pipe, one side of the shell is fixedly connected with a supporting rod, the rod wall of the supporting rod is connected with a transmission mechanism, the end, away from the shell, of the supporting rod is fixedly connected with a tail plate, one side of the shell is sleeved with a transverse plate through a strip-shaped through hole, and one end of the transverse plate is connected with the transmission mechanism. According to the passive ventilation device for the resident house, natural wind can be captured when the wind is small, the ventilation quantity of the ventilation device can be improved in an auxiliary mode, meanwhile, the ventilation quantity of the ventilation device is limited when the wind is large, the ventilation quantity of the ventilation device is balanced, and the influence of the natural wind speed on the ventilation device is effectively reduced.

Description

technical field [0001] The invention relates to the technical field of house ventilation, in particular to a passive ventilation device for residential houses. Background technique [0002] House ventilation is an important aspect that affects the quality of the indoor environment, and it has an important impact on the health of the indoor environment and the energy consumption of the building. Ventilation is an important means to improve the indoor air environment. Usually, mechanical or natural methods are used to make the wind unobstructed and can pass through and reach the room or a sealed environment to create a suitable air environment such as hygiene and safety. The roof is the first choice for ventilation equipment. Location, among them, roof ventilator is a common ventilation device for house ventilation, also called roof natural ventilator, roof natural ventilator, etc., mainly around the aerodynamic wind carrier type theory, that is, when the wind acts on the obje...

AI Technical Summary

Problems solved by technology

[0003] At present, although the house ventilator uses aerodynamics to make the room in a negative pressure state to achieve the purpose of ventilation, but due to the instability of the natural wind, the ventilation speed of the ventilator changes with the wind speed of the natural wind, that is, the wind speed of the external natural wind is relatively large. When the wind speed increases, the ventilation volume of the ventilator also increases, and the wind capture ability of the ventilator is poor. When the natural wind is small, the speed of the ventilator is small, and the purpose of ventilation to change the indoor environment cannot be achieved.
