In order to improve the heating efficiency of high-temperature steam to food, the inner tank of the steam oven is usually designed as a closed structure, which heats the food faster and maintains the nutrition and taste of the food. However, when the baking heating method is adopted, the internal air pressure is balanced. The existence of the food itself can not be effectively discharged through the existing exhaust structure after being evaporated by heat, which will result in a large internal humidity.

Therefore, the steam ovens currently on the market can obtain better baking effects when grilling some foods that do not require high internal humidity, such as roast chicken, barbecue, etc., and for humidity-sensitive foods such as cakes and breads. The steam generated during heating directly affects the fermentation and baking effect of the food, and is prone to problems such as poor shape, insufficient fermentation, high humidity, and poor mouthfeel; therefore, the commercially available steam oven does not even cook the cake. It can achieve the baking effect of ordinary oven, which seriously affects the promotion and use of the new kitchen appliances such as steam oven. Therefore, it is necessary to improve the structure of the existing steam oven so that it can satisfy the steam heating mode. The sealing requirement under the formula can achieve excellent baking effect in the baking mode.

detailed description

Referring to Figures 1 to 3, a steam oven with a toasting blast structure includes a casing 1 having a liner 2 that can be closed by closing the tank door, and a steam for the liner 2. a steam generating device 3, a water tank 4 for supplying water to the steam generating device 3, and an air discharging device 5 for exhausting the inner tank 2, and the drum 1 is further provided with a drum for inputting air for the inner tank 2 during baking and heating The air device 6 forms a steam discharge passage with the air exhaust device 5, so that the steam oven can input relatively dry air through the air blowing device 6 during baking and heating, and discharge the steam generated by the food to avoid baking heating. When the internal humidity is too large, good fermentation can be achieved when baking cakes and breads, so that the steam oven can not only meet the sealing requirements in the steam heating mode, but also improve the steam heating efficiency and the dry ventilation in the baking mode. Requires an excellent baking effect.

Wherein, the inner wall of the inner tank 2 is provided with an air inlet 21, and the air blowing device 6 includes a blower 7 and an air blowing duct 8 that communicates the air blower 7 with the inner air inlet 21; preferably, the air blowing device 6 is disposed in the cabinet 1 Further, the air inlet of the air blower 7 is located in the cavity between the casing 1 and the inner tank 2 on the back side of the inner casing 2 in the cavity between the inner casing 2.

Since the internal space between the casing 1 and the inner tank 2 of the steam oven is relatively closed, the heat source of the internal space is mainly concentrated at the back of the inner tank 2 during operation, so that the internal space is heated, which easily leads to internal wiring and electrical components. Aging, damage, so the air inlet of the blower 7 can be set in the cavity of the back of the inner tank 2, one is to enhance the heat dissipation effect of the internal space; the second is that the air entering the blower 7 has a certain temperature to avoid entering the inner tank 2 After the temperature difference between the original high temperature steam and the original high temperature steam is too large, and the time required to reach the heating temperature is shorter, the heating energy consumption of the heating device for the incoming air is reduced.

Of course, the air inlet of the air blower 7 can also be disposed outside the casing 1, and since the blast duct 8 is located in the cavity between the cabinet 1 and the inner tank 2 having a relatively high temperature, the cold air entering can also be entered. Plays a preliminary heating effect.

In this embodiment, the air blowing device further includes an on-off valve 9 capable of preventing backflow of gas in the inner tank 2. The on-off valve 9 may be a one-way valve, or may be synchronized with the blower 7 when the steam is too large during baking and heating. Open solenoid valve.
