実開昭54−45288号公報参照）。 Conventionally, in this type of oven, a fan for circulating hot air is provided in a heating chamber having a hot air supply port and a hot air discharge port, and an exhaust cooling fan is provided at the rear of the heating chamber. The housing is housed in a casing having an inlet port and an outlet port, and a common duct is provided for merging the outlet port with the exhaust port, and the duct is installed at the rear of the casing at the back near the merging point. It is known to bulge out and open outward at the upper end (see, for example, Japanese Utility Model Application No. 54-45288).

たことを特徴とする。 In this case, the reason for providing the bulge in the duct is
The exhaust gas mainly flowing out from the exhaust port of the heating chamber pushes the cold air flowing out from the discharge port of the casing, which tends to obstruct this outflow, toward the bulging part, so that the exhaust gas is obstructed. This is to ensure that the cold air joins with the cold air, is properly cooled by the cold air, and is smoothly discharged to the outside of the duct together with the cold air. As the distance between the back of the duct and the back of the oven main body surrounding the duct becomes closer, the back of the oven main body tends to be overheated by the hot air from inside the heating chamber in the bulge, and when the oven is not used. Not good. The purpose of the present invention is to improve the conventional oven described above so that the back side of the oven body does not overheat.As shown in Fig. 1, the present invention has a hot air supply port 1 and a hot air discharge port 2. A hot air circulation fan 4 is provided in the heating chamber 3 having
An exhaust cooling fan 5 is installed behind the heating chamber 3, and the exhaust cooling fan 5 is connected to an intake port 6 and an exhaust port 7.
The exhaust port 7 is housed in a casing 8 having a
A common duct 9 is provided for merging the casing 8 with the discharge port 2, and the duct 9 is bulged out to the rear of the casing 8 at the back near the merging point, and opened to the outside at its upper end. The hot air circulation type oven is characterized in that a through hole 10 is provided on the back surface of the duct 9 to guide cold air outside the casing 8 to the confluence point.

is located on the rear side of the casing 8 and both fans 4 and 5
The motors driving the are shown respectively.

くなるようにした。 In the illustrated example, a passage 1 extending vertically along the back surface of the casing 8 is provided below the bulge 9a of the duct 9.
6 is provided and communicated with the through hole 10 so that the cold air outside the casing 8 can be easily guided to the confluence point 17 with the hot air.

排出される。 Next, to explain its operation, when the burner 14 and the motor 15 are driven, the hot air in the combustion chamber 13 by the burner 14 is sucked into the heating chamber 3 through the supply port 1 by the hot air circulation fan 4. , are circulated within it. During this time, hot air in the combustion chamber 13 is constantly supplied through the supply port 1, and a portion of the hot air in the heating chamber 3 is discharged through the discharge port 2. This exhaust air is directed toward the bulging portion 9a of the duct 9, and includes cold air outside the casing 8 through the inside of the casing 8 sucked by the exhaust cooling fan 5, cold air outside the casing 8 through the through hole 10, and the bulging portion 9a.
After being cooled by the cold air, the cold air is discharged to the outside from the upper end of the duct 9 together with the cold air.

１０を設けた場合は、15deg程度の低温となる。 Here, when we actually measure the temperature at the back of the oven body behind the bulging part 9a, it is quite high at about 35 deg in a conventional oven without a through hole in the duct, but as in the present invention, the temperature in the duct 9 is quite high. When the through hole 10 is provided on the back surface, the temperature becomes about 15 degrees.

りでなく、モータ１５を冷却する役目をも果す。 Note that when the intake port 6 of the casing 8 is provided on the motor 15 side as shown in the figure, the exhaust cooling fan 5
serves not only to guide cold air into the bulging portion 9a of the duct 9, but also to cool the motor 15.

A gas table 19 is provided in the upper part via a cooling passage 18, and a gas control chamber is placed on the side of the door 11 of the heating chamber 3, but the configuration of other parts is almost the same as that shown in Fig. 1. Therefore, the same reference numerals will be given and the explanation will be omitted.

る。 In this way, according to the present invention, there is a common type 1 in which the hot air flowing out from the heating chamber 3 and the cold air from the exhaust cooling fan 5 are combined in the bulging part.
A through hole 10 is provided on the back surface of each duct 9, and the cold air outside the casing 8 of the exhaust cooling fan 5 is guided to the confluence point through the through hole 10 to cool the bulging portion. Therefore, the back side of the oven main body, which is relatively close to the bulge, is not overheated, and the oven can be used safely.
