Technical Field

The present invention relates to the field of household appliances, in particular to an implicit heating ventilation window, and specifically to an implicit heating ventilation window based on the Bernoulli effect.

Background technique

Usually, in buildings such as office buildings or residential buildings, ventilation is mostly carried out through windows, but this method causes outdoor air to flow into the room rapidly, which not only easily causes the loss of cooled and heated air, but also causes a problem of reduced thermal efficiency as the cooled and heated air is discharged through the windows.

The existing building ventilation technology has certain deficiencies and defects. Installing ventilation fans on the building facade affects the appearance and damages the integrity of the wall. The ventilation duct penetrates the wall, destroying the integrity of the building envelope structure, and there is a thermal bridge effect, which has defects in the building's thermal performance and damages the wall's thermal insulation performance.

Working principle: In summer, open the openable window sash, and the air enters the room through the heating ventilation window purlin and the ventilation window frame. Based on the Bernoulli effect, the gas discharged from the air outlet (the airway toward the middle of the air outlet window frame) forms an airflow, which drives the air in the ventilation window frame forward through viscosity. In theory, it can discharge 15 times the amount of air passing through the ventilation window frame, thereby enhancing the air circulation between indoor and outdoor. In winter, close the openable window sash, and the air enters the room through the heating ventilation window purlin, thereby achieving the effect of heating and ventilation in winter.

The heated ventilation window purlin draws air into the ventilation window frame from bottom to top, filters and heats the air in sequence, and finally outputs the air on the openable window sash side through the Bernoulli effect.

Embodiment: In the embodiment of the present invention, the power system is a motor. The fresh air collection system is composed of a ventilation grille filter at the air inlet, a rotating shaft and a wind turbine to suck the wind near the outdoor air inlet into the heating ventilation window purlin. A filter core skeleton is attached to the outside of the filter device, and nano antibacterial cloth, a large particle interception layer, a PM core interception layer, and a catalyst decomposition layer are arranged from bottom to top. The inhaled air is filtered and purified layer by layer through four layers of filter devices. The heating device uses a heating tungsten wire.

The size of the window frame and the window sash is variable, and the window frame profile is an ordinary window frame. The openable window sash is composed of window frame profile 4, window frame profile 5 and glass, which is connected to window frame profile 4 through a hinge and can be opened. The air coming out of the heating and ventilation window purlin is distributed with several random air outlets in the window purlin shell, and then enters the air outlet window frame through the air holes of window frame profile 3, and enters the room through the air outlet. In summer, the window sash is opened, and the air enters the room through the entire ventilation window frame through the heating and ventilation window purlin. Based on the Bernoulli effect, the gas discharged from the air outlet forms an airflow, and the airflow will drive the air in the window frame to move forward through the viscosity. With the superposition effect, theoretically, 15 times the amount of air can be discharged into the ventilation window frame, thereby enhancing the air circulation between indoor and outdoor. In winter, the openable window sash is closed, and the air enters the room through the heating and ventilation window purlin through the entire ventilation window frame. The outdoor air enters the room through filtration, purification and heating, thereby achieving the effect of heating and ventilation in winter.
