Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a gas oven device for home or commercial use.

[Conventional technology and its problems]

As shown in FIG. 1, a conventional gas oven device has a burner installed at the bottom of a heating chamber, and heats the food by convection of air heated by the burner. Such conventional gas oven devices use a relatively large burner and provide an exhaust port at the top of the device to allow combustion to be carried out in an open atmosphere. Therefore, when the door was opened, the work was hindered by being blown away by the exhaust gas. The present invention solves these problems and makes the temperature distribution within the heating chamber uniform.

[Means to solve the problem]

Two combustion chambers are constructed by installing heat transfer plates at the upper and lower parts of the heating chamber, and the combustion chambers are
The configuration is as follows.

A burner is installed on the front side of the combustion chamber, a chevron-shaped heat shield plate is installed in the horizontal direction on the heat transfer plate on the burner side, and a heat transfer plate is installed on the heat transfer plate on the rear side of the combustion chamber. A gas oven device, wherein a promoter is provided, and the combustion chamber is communicated with an exhaust fan.

[Effect]

When the burners start combustion in the two upper and lower combustion chambers, the combustion gas heats the heat exchanger plate, and the heat exchanger plate heats the food in the heating chamber from above and below.
Since the combustion gas is forcibly discharged by the exhaust fan, the food to be cooked in the heating chamber is heated only by radiant heat. In such cases, the chevron-shaped heat shield plate installed horizontally on the heat exchanger plate inside the combustion chamber avoids concentrated heating in the center of the heat exchanger plate, makes the temperature distribution uniform in the left and right direction, and improves the temperature distribution on the rear side of the combustion chamber. The heat transfer promoting means provided on the heat transfer plate promotes the heat transfer effect in the front-rear direction of the heating chamber and makes the temperature distribution in the front-rear direction uniform.

〔Example〕

Two combustion chambers 4 and 4' are constructed by installing heat exchanger plates 3 at the upper and lower parts of the heating chamber 1,
The combustion chambers 4, 4' have the following configuration. That is,
A burner 2 is installed on the front side of the combustion chambers 4 and 4',
A chevron-shaped heat shield plate 5 is provided on the heat transfer plate 3 on the side of the burner 2.
are installed in the left-right direction, a heat transfer promoter 6 is provided on the heat transfer plate 3 on the rear side of the combustion chambers 4, 4', and the combustion chamber is communicated with an exhaust fan. The heat transfer promoter 6 may be a fin.

[Effect]

In the above configuration, when the burner 2 starts combustion, the combustion gas heats the heat transfer plate 3, and the heat transfer plate 3 heats the food to be cooked in the heating chamber 1. The combustion gas is
Since it is forcibly discharged by the exhaust fan 7,
The food to be cooked in the heating chamber 1 is heated only by radiant heat from the upper and lower heat transfer plates 3. In this case, the mountain-shaped heat shield plate 5 avoids concentrated heating at the center of the heat transfer plate 3 and makes the temperature distribution uniform in the left and right direction, and the heat transfer promoting means 6 improves the heat transfer in the front and back direction of the heating chamber 1. Promote the thermal effect and make the temperature distribution uniform in the front-back direction.

[Effect of idea]

As mentioned above, this invention has combustion chambers above and below the heating chamber, and no exhaust gas is introduced into the heating chamber, so even if the oven door is opened, there is no chance of being blown away by the combustion gas. When used for commercial purposes, the workability and working environment can be significantly improved, and the unique configuration described above equalizes the temperature distribution in the front-rear and left-right directions of the heating chamber. This has the advantage that the temperature distribution in the heating chamber is made uniform overall by combining with the heating from the combustion chamber, and cooking can be performed in a cooperative manner.
