Confirmation Middle of the road. The exhaust passage is provided on the side wall of the front side of the exhaust valve with a pressure relief exhaust hole, and the exhaust hole communicates with the exhaust passage and the cooking chamber.

The exhaust steam fan is disposed at one end or middle portion of the exhaust passage and behind the exhaust valve; the exhaust passage is provided with an air inlet at the exhaust fan, and the air inlet is connected to the outside; the exhaust passage is another One end is connected to the outside world. The outlet of the exhaust passage is disposed at the top of the furnace body, and the exhaust wall is disposed on the side wall and/or the top wall of the top of the furnace body; the air inlet is disposed on the exhaust hood of the cavity, and the air inlet is disposed in the cooking chamber The control chamber of the side, the electrical control component is connected, and the bottom of the control chamber is provided with an air inlet slit or an air inlet to communicate with the outside. .

The above-mentioned exhaust passage is composed of an exhaust hood and a ventilating cover of the cavity. The spliced cavity exhaust hood and the exhaust hood cover form a rotary hollow cavity. A sealing strip is disposed between the chamber exhaust hood and the exhaust hood. The cavity exhaust hood and the top wall of the cooking chamber are integrated. The solenoid valve and the exhaust fan are electrically connected to the main controller of the electric steam boiler, respectively, and the main controller is disposed in the control chamber.

In the cooking process of the present invention, as the amount of steam in the cooking chamber is continuously increased, the air pressure in the furnace chamber is also continuously increased while cooking the food. By connecting the exhaust passage and the pressure relief exhaust hole of the cooking chamber, excessive steam in the cooking chamber is gradually released to the outside to prevent the air pressure in the cooking chamber from being too high, thereby causing danger; at this time, the exhaust steam for rapid exhausting The valve is always closed.

When the cooking is finished, the cooking chamber of the electric steamer is filled with high-temperature steam. If the user directly opens the door to take the food, there is a danger of being burnt. At this time, the exhaust fan can be activated by the main controller, or the exhaust fan can be automatically activated by a preset program; at the same time, the main controller gives an opening command to the solenoid valve, and the electromagnetic wide stem pushes the exhaust valve to open. The high-speed rotating exhaust fan generates a strong airflow, and the airflow passes through the exhaust valve along the exhaust passage, taking away a large amount of steam discharged from the cooking chamber, and is arranged by the side wall and/or the top wall of the top of the furnace body. The steam outlet is discharged; at the same time, the temperature in the cooking chamber is rapidly lowered.

After the above process, when the user opens the oven door to take food, the steam in the electric steamer has been based. This discharge, and the temperature inside the electric steamer is also greatly reduced, the user can easily take out the food, there is no possibility of being burnt.

When the exhaust fan of the present invention is in operation, since the intake air is carried out through the air inlet slit provided at the bottom of the control chamber and communicating with the outside, when the intake air flow passes through the control chamber, it is bound to be Taking away the high temperature gas in the control chamber, which reduces the temperature in the control chamber and reduces the operating temperature of the electrical control components including the main controller, which greatly prolongs the service life of the electric steam boiler.

The invention has the advantages of simple and reasonable structure, safe and reliable operation, high heating efficiency, high and rapid discharge of excess steam in time, avoiding user injury caused by superheated steam, and timely taking away more fortunate heat, thereby greatly prolonging the service life of the product.
