2. Description of the Related Art In commercial kitchens such as cafeterias and restaurants, combustion exhaust gas and cooking exhaust gas discharged from cooking appliances are collected by an exhaust hood and then discharged outside through a duct by an exhaust fan. The exhaust hood is separated from the cooking appliance, the exhaust hood is installed on the ceiling, and the cooking appliance is installed on the floor. Of the cooking appliances, flyers are generally installed below the exhaust hood due to the generation of oily smoke, etc.In addition, a grease filter is installed in the exhaust hood to remove oil, oily smoke, impurities, etc. I have to. FIG. 3 conceptually shows the configuration of such a conventional kitchen room, wherein reference symbol a denotes cooking equipment, b denotes an exhaust hood, c
Is a grease filter, d is a duct, e is an exhaust fan, f is a duct connected to an air conditioner, and g is a pantry.

[0003]

The construction of such a kitchen room has the following problems. Among the cooking appliances, the flyer is very difficult to clean because the oil scatters on the surrounding walls and floor. Even if the combustion exhaust gas and the cooking exhaust gas are collected by the exhaust hood, since the distance between the cooking device and the exhaust hood is long, there is overflow of the cooking exhaust gas and the combustion exhaust gas containing oil smoke, and the indoor environment is deteriorated. Such overflows also increase the temperature in the kitchen room and increase the air conditioning load. Accordingly, an object of the present invention is to solve such a problem.

[0004]

In order to solve the above-mentioned problems, according to the present invention, there is provided a cooking section using a burner, and a cooking section behind the cooking section.
An exhaust hood is connected to the upper side of the cooking device body to cover the side, rear and upper sides of the cooking unit, and extends from below to above. A cooking exhaust passage is formed, and a rear side of the exhaust hood is partitioned by a partition wall to independently cover the periphery of the combustion exhaust portion to form a combustion exhaust passage extending from below to above, and the combustion exhaust passage and the cooking exhaust passage are formed. Proposes an exhaust hood-integrated cooking apparatus in which a grease filter is installed on the cooking exhaust passage side of the junction and a duct connection part is provided downstream of the junction, together with the configuration of merging at the upper part of the exhaust hood. .

According to the present invention, in the above configuration,
It is proposed that the side wall that covers the side surface above the cooking unit be narrower toward the bottom.

In the present invention, it is proposed that a falling object shielding plate composed of a plurality of plates having a ventilation space is provided on the combustion exhaust passage side of the junction in the above configuration.

Further, according to the present invention, in the above configuration,
The fallen object shield plate on the lower side also burns from the partition wall at the junction.
The structure is inclined upward on the side of the burning exhaust passage.
Dropping objects below the lower end of the shielding plate and toward the cooking exhaust passage
It is proposed to configure a falling object collecting unit that collects oil droplets that fall from the shielding plate via the junction .

Further, the present invention proposes that an air passage is provided on the rear surface side of the combustion exhaust passage, and a communication portion with the air passage is provided upstream of the combustion exhaust passage.

[0009]

The cooking exhaust gas from the cooking section of the cooking device rises in the cooking exhaust passage and joins the combustion exhaust passage after passing through the grease filter. Further, the combustion exhaust gas from the burner of the cooking device rises in the combustion exhaust passage and joins with the cooking exhaust gas, and is discharged outside the room by the exhaust fan through the duct connected to the duct connection portion.

[0010] Since the cooking exhaust passage covers the side surface and the rear surface immediately from the upper end of the cooking section, the cooking exhaust gas does not overflow in these directions and is efficiently collected. Further, since the combustion exhaust passage is configured to pass the combustion exhaust independently before it joins the cooking exhaust passage at the upper part of the exhaust hood, the combustion exhaust is not discharged at all into the kitchen room.

The workability of the cooking section is favorably maintained by forming the side wall of the exhaust hood narrower as it goes downward.

If a fallen object shielding plate is provided on the combustion exhaust passage side, the oil that has not been collected by the grease filter collects after merging and drops as an oil droplet. The drop to the upstream side of the exhaust passage can be prevented, and therefore, the combustion of oil droplets can be prevented. most
