A solar window ventilation device

Abstract

The invention provides a solar energy window-type ventilation device which comprises a sleeve arranged on a glass window. The surface of the sleeve is provided with outer threads. The sleeve is fixed to the glass window through a locking screw cap. The outdoor end face of the sleeve is provided with a solar cell plate and a shutter, and the indoor end face of the sleeve is provided with a waterproof baffle. A half-cylinder-shaped air bellow is arranged above the position, in the sleeve, of the waterproof baffle, a centrifugal fan is arranged in the half-cylinder-shaped air bellow. Exhaust is sent outside the glass window through the shutter. A centre positioning cylinder is connected with the waterproof baffle and the solar cell panel. A semicircular filter screen grid and a semicircular wind screen form a circular rotating body, and the circular rotating body is fixed to the center positioning cylinder through a manual bolt. According to the solar energy window-type ventilation device, electric power is generated through the solar cell plate at daytime to be supplied to the centrifugal fan so as to conduct indoor ventilation, a timer is automatically connected to an external power source at night to supply power to the centrifugal fan, indoor air ventilation can be effectively kept, air quality in an air-conditioned room is improved, and the solar energy window-type ventilation device has the advantages of saving energy and protecting the environment and being easy to install.

Description

technical field [0001] The invention relates to a ventilation device, in particular to a solar window ventilation device. Background technique [0002] At present, the indoor ventilation of residents is mainly carried out in the form of opening windows. In the current situation of serious air pollution, the outdoor air environment has a considerable impact on people's health, and a certain amount of indoor air will also be generated in closed air-conditioned rooms. Therefore, it is very necessary to discharge the indoor polluted air and ensure the circulation and clean exchange of indoor and outdoor air. The patent of "a household solar window ventilation device" described in Patent No. 201320179408. Solar ventilation device, the ventilation device is equipped with louvers, filter screens, fans and solar panels inside and outside the two connected casings. The ventilation duct of the above structure is a horizontal straight-through type, and the sealing and isolation effect ...

[0002] At present, the indoor ventilation of residents is mainly carried out in the form of opening windows. In the current situation of serious air pollution, the outdoor air environment has a considerable impact on people's health, and a certain amount of indoor air will also be generated in closed air-conditioned rooms. Therefore, it is very necessary to discharge the indoor polluted air and ensure the circulation and clean exchange of indoor and outdoor air. The patent of "a solar window ventilation device for household use" described in patent number 201320179408. Solar ventilation device, the ventilation device is equipped with louvers, filter screens, fans and solar panels inside and outside the two connected casings. The ventilation duct of the above structure is a horizontal straight-through type. The rainwater is easy to enter the room, and the length of the ventilation pipe is long. The solar panel is located at the tail, which causes the center of gravity of the whole device to be behind, which will have an adverse effect on the glass windows. Therefore, it is necessary to redesign the waterproof and overall structure. At the same time, it is necessary to take into account the structure of the existing glass windows, and the technical solution requires reliability, practicality and implementability
