Oven

By setting up a smoke vent and smoke exhaust channel on the rear side of the top surface of the oven cavity, combined with the natural rise of hot air and the airflow pressure difference in the duct, the problem of difficult smoke exhaust in the oven is solved, achieving smooth smoke exhaust and stable internal oven temperature.

AI Technical Summary

⚠Technical Problem

The design of existing oven exhaust channels makes it difficult for oil fumes to escape smoothly, causing oil fumes to accumulate and potentially turn into sludge, affecting the internal temperature stability of the oven and user safety.

⚗Method used

The first exhaust vent is set on the rear side of the top surface of the oven cavity, and the second exhaust vent is connected through the exhaust channel between the heat insulation plate and the top surface of the cavity. The natural rising characteristics of hot air and the air pressure difference in the duct ensure that the fumes are discharged smoothly.

🎯Benefits of technology

It effectively prevents the accumulation of oil fumes, lowers the internal temperature of the oven, prevents oil fumes from dripping onto the food surface after cooling, ensures the stability of the internal temperature of the oven and user safety, and improves the efficiency of smoke extraction.

Abstract

This utility model relates to the field of kitchen appliances technology and discloses an oven, including an inner cavity and a heat insulation plate and a baffle plate sequentially disposed above the top surface of the inner cavity. Along the front-rear direction of the inner cavity, a first exhaust vent is provided on the rear side of the top surface of the inner cavity, communicating with its interior. A second exhaust vent is provided on the heat insulation plate in front of the first exhaust vent. An exhaust channel is provided between the heat insulation plate and the top surface of the inner cavity, and the first and second exhaust vents are connected through the exhaust channel. An air duct is provided between the baffle plate and the heat insulation plate, with both ends of the air duct connected to the air outlet of a fan and the outside atmosphere, respectively. Along the front-rear direction of the inner cavity, the second exhaust vent is connected to the air duct and located between the two ends of the air duct. When the fan is running, a rapidly flowing airflow is formed in the air duct, creating a pressure difference between the inner cavity and the air duct. The fumes inside the inner cavity are then drawn into the air duct through the first exhaust vent, the exhaust channel, and the second exhaust vent under the action of this pressure difference, and are discharged with the help of the airflow within the air duct.
