Abstract

PURPOSE:To realize a safe and sanitary discharging device for cooking operation by a method wherein an oil removing hole is opened at a lower part of a vane casing and then an oil reservoir for receiving oil dripped from the oil removing hole is arranged. CONSTITUTION:An oil removing hole 11 is opened at a lower part of a vane casing 12 of a discharging air blower 8 and an oil reservoir 9 which is removably attached for use in receiving oil dripped from the oil removing hole 11 is provided. When the discharging air blower 8 is operated, oily smoke and odor and the like generated from a cooking device 1 are sucked from a front part of the cooking table 2 and guided by an airstream flowed along an air stream guiding plate 5 and a top lid 4 toward the suction port 3, sucked through the suction port 3, passed through an aeration passage 10 and a discharging duct 7 and discharged out of a room. At this time, the sucked oily smoke is flows toward an inner wall of a vane casing 12 due to a centrifugal force of a vane wheel 13, oil and fat substances in the oily smoke are adhered to the inner wall of the vane casing 12, dripped from the oil removing hole 11 at the lower part of the vane casing 12, resulting in that oil is not accumulated within the vane casing 12.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a cooking exhaust device for exhausting carbon dioxide, oil smoke, odor, etc. generated from a cooking appliance to the outside.

2. Description of the Related Art Conventionally, this type of exhaust system for cooking was disclosed in Japanese Patent Publication No. 60-5381.
The configuration was as described in Publication No. 7. However, with such a configuration, a large amount of exhaust air is required to suck in the oil smoke, odor, etc. that try to escape from side to side, resulting in high noise. We are proposing an exhaust system for cooking.

In FIG. 2, a suction port 3 is provided at the rear upper part of a cooking table 2 on which a cooking device 1 is placed, air flow guide plates 6 are provided on the left and right sides of the upper surface of the cooking table 2, and a canopy 4 is provided above.

The canopy 4, the airflow guide plate 6, and the back plate 6 are integrated to form a hood. The suction port 3 is connected via a ventilation path 1o to an exhaust blower 15, which is composed of a centrifugal impeller 13 and a blade casing 14, which are installed inside the cooking table 2, and is connected to the outdoors via an exhaust duct 7. It's communicating.

In the above configuration, when the exhaust blower 16 is operated, oily smoke, odor, etc. generated from the cooking device 1 are sucked in from the front of the cooking device table 2 and are absorbed into the airflow flowing along the airflow guide plate 6 and the canopy 4 toward the suction port 3. It was guided, sucked in through the suction port 3, passed through the ventilation path 1o, the exhaust duct 7, and was discharged outdoors.

Problems to be Solved by the Invention In such a conventional configuration, the oil and fat in the oil smoke is blown to the inner wall of the blade casing by the centrifugal force of the impeller, adheres to it, and accumulates inside the blade casing, which is a disaster prevention problem. The problem was that it was dangerous. Additionally, there was a problem in that the amount of exhaust air was reduced due to the accumulated oil.

The present invention solves these problems and aims to provide a safe and clean cooking exhaust system.

Means for Solving the Problems In order to solve this problem, the present invention provides a ventilation passage having an inlet provided at the rear upper part of a cooking table on which a cooking appliance is arranged, and an exhaust air passage to which this ventilation passage is connected. It consists of a blower and an oil drain hole opened at the bottom of the blade casing of this exhaust blower.

Function: With this configuration, oil drips to the outside of the blade casing from the oil drain hole, so oil does not accumulate inside the blade casing and the ventilation area of the blade casing does not change.

EXAMPLE Hereinafter, an example of the present invention will be described based on FIG. An oil drain hole 11 is opened at the lower part of the blade casing 12 of the exhaust blower 8, and a removable oil reservoir 9 is provided to receive oil dripping from the oil drain hole 11. The other configurations are the same as the conventional example.

When the exhaust blower 8 is operated in the above configuration, the cooking device 1
The oil smoke, odor, etc. generated from the cooking table 2 are sucked in from the front of the cooking table 2, guided by the airflow flowing toward the suction port 3 along the airflow guide plate 6 and the canopy 4, and sucked out from the suction port 3. It passes through duct 7 and is discharged outdoors. At this time, the sucked oil smoke is blown to the inner wall of the blade casing 12 by the centrifugal force of the impeller 13, and the oil and fat in the oil smoke adheres to the inner wall of the blade casing 12 and drips from the oil drain hole 11 at the bottom of the blade casing 12. Therefore, oil does not accumulate inside the blade casing 12. Further, the dropped oil will accumulate in the oil reservoir 9. Furthermore, since the oil sump cage 9 is detachable, the oil accumulated in the oil sump 9 can be easily disposed of, and the oil sump 9 can be made smaller.

Effects of the Invention As is clear from the above description of the embodiments, according to the present invention, an oil drain hole is opened at the bottom of the blade casing, and an oil reservoir is provided to receive oil dripping from the oil drain hole, thereby preventing the inside of the blade casing from being damaged. This prevents oil from accumulating and provides a safe and clean cooking exhaust system. Further, since oil does not adhere to the inside of the vane casing and reduce the ventilation area, it is possible to prevent a decrease in the exhaust air volume and an increase in ventilation noise.
