Energy-saving and environment-friendly fresh air supplying device for kitchen

Abstract

The invention discloses an energy-saving and environment-friendly fresh air supplying device for a kitchen. The device is cooperated with a kitchen lampblack machine or an exhaust fan in use and comprises a heat exchange pipe and a fresh air purification device connected with the heat exchange pipe; the heat exchange pipe is arranged in an exhaust duct connected with an outlet of the kitchen lampblack machine or the exhaust fan, and a heat exchange pipe inlet and a heat exchange pipe outlet in the two ends of the heat exchange pipe are exposed out of the exhaust duct; the fresh air purification device is provided with an air inlet communicated with the outdoor, and an air outlet communicated with the heat exchange pipe inlet, and an air valve and a dust filter net are arranged between the air inlet and the air outlet in sequence. The energy-saving and environment-friendly fresh air supplying device for the kitchen is reasonable in structure, and can automatically supply fresh air to the enclosed kitchen so as to improve the smoke exhaust or air exhaust efficiency of the kitchen lampblack machine or the exhaust fan.

Description

technical field [0001] The invention relates to a kitchen matching device, and in particular provides an energy-saving and environment-friendly kitchen supplementary fresh air device. Background technique [0002] At present, a range hood or an exhaust fan is installed above the stove in the kitchen for the purpose of exhausting the smoke generated during the cooking process to the outside. However, when the doors and windows are closed, when the range hood / exhaust fan is working, the indoor air pressure will be lower than the outdoor air pressure, and the flow rate of the exhaust smoke (wind) is significantly smaller than the flow rate when the window is opened, reducing the range hood / exhaust air flow rate. The working efficiency of the fan and the effect of exhausting smoke (wind) are poor. [0003] Therefore, how to eliminate the negative pressure produced when the range hood / exhaust fan works when the doors and windows are closed, improve the working efficiency of the ...
