Abstract

PURPOSE:To reduce the exhaust air temperature, and prevent the overheat of the exhaust air passage from happening. CONSTITUTION:For a gas cooker such as an oven, etc., which heat-cooks an object to be heated being put in the chamber, cooling means 7, 8 to feed outside air, in an exhaust air passage which connects the chamber and an exhaust air port 4. Hot air which is sent out from the inside of the chamber to the exhaust air port is mixed with cold air which is fed from the outside of the chamber, and the temperature is lowered.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a gas cooker such as an oven in which objects to be heated are stored in a refrigerator.

[0002]

2. Description of the Related Art In a gas cooker such as an oven that heats and cooks an object to be heated, the hot air in the chamber is discharged directly to an exhaust port.

[0003]

By the way, in recent years, a gas cooker has been proposed which can raise the temperature in the refrigerator higher than the conventional one in order to make the surface of the object to be heated brown. Such gas cooker, 400
Exhausting the hot air in the refrigerator, which may reach as high as 0 ° C., to the exhaust port as it is has various problems in terms of safety and durability of the exhaust passage.

The present invention has been made in view of the above points, and an object thereof is to provide a gas cooking appliance capable of reducing the exhaust gas temperature and avoiding overheating of the exhaust passage. It is in.

[0005]

SUMMARY OF THE INVENTION According to the present invention, however, in a gas cooking utensil such as an oven that heats and cooks an object to be heated, the outside air is introduced into an exhaust passage extending from the inside to the exhaust port. It is characterized in that a cooling means for feeding is provided.

[0006]

According to the present invention, the temperature of the hot air sent from the inside to the exhaust port is lowered because it is mixed with the cold air of the outside air sent by the cooling means. If the cooling means is composed of a self-cooling fan that is provided in a motor for driving a fan for circulating heated air and blows outside air to the motor, and a cool air passage that connects the motor peripheral space and the exhaust passage, that is, this type If the self-cooling fan provided for cooling the motor is used in the gas cooker, the exhaust gas temperature can be lowered without increasing the cost.

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail below with reference to the illustrated embodiments. In this gas cooker, as shown in FIG. 1, air heated by a burner 2 is circulated in a compartment 1 by a circulation fan 3. This is an oven that raises the temperature of the inside of the refrigerator 1, and part of the air sent out by the fan 3 flows to the exhaust port 4. Here, the driving motor 5 of the fan 3 is arranged in a place partitioned by a partition wall 6 from the compartment 1 and the installation portion of the fan 3 so as to avoid being affected by the temperature of the compartment 1 as much as possible. It has been done,
Since high-temperature hot air of 500 to 600 ° C. passes through the fan 3, the motor 5 is usually provided with a self-cooling fan 7. In the present invention, the middle of the exhaust passage connecting the inside 1 and the exhaust port 4 and the space around the motor 5 are connected by the cool air passage 8, and the outside air blown to the motor 5 by the self-cooling fan 7 is further The temperature of the exhaust gas is lowered by sending it to the exhaust path side through the cold air path 8 and mixing it with the hot air.

FIG. 2 shows a circulation path formed by a fan 3 and an exhaust port 4.
It is applied to a gas cooking appliance in a form in which the exhaust passage leading to the above is separated.

[0009]

As described above, in the present invention, the exhaust temperature is lowered because the hot air sent from the inside to the exhaust port is mixed with the cold air of the outside air sent by the cooling means. Accordingly, there is no problem even if the heat resistance of the exhaust passage is reduced, and measures such as strength against thermal stress can be reduced, so that safety can be improved and cost can be reduced at the same time.

Further, the cooling means may be composed of a self-cooling fan which is provided in a driving motor of a fan for circulating heated air and blows outside air to the motor, and a cool air passage which connects a space around the motor and an exhaust passage. In other words, if the self-cooling fan provided for cooling the motor in this type of gas cooking utensil is used, there is no increase in cost due to the provision of the cooling means.
