JPH067016B2 - Exhaust device for cooking - Google Patents

Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an exhaust system for cooking that exhausts carbon dioxide, oil, smoke, odor, etc. generated from a cooker to the outside.

2. Description of the Related Art Conventionally, an exhaust device for cooking of this type is disclosed in Japanese Patent Publication No. 60-5381.
The structure is as shown in Japanese Patent Laid-Open No. 7. However, in such a structure, there is a problem that oil adheres to the inside of the exhaust duct. Therefore, we have already proposed the method shown in FIGS. 3 and 4. In the figure, a suction port 3 is provided in the upper rear portion of a cooker base 2 equipped with a cooker 1 such as a gas stove, and airflow guide plates 10 are provided on the upper and left sides of the upper surface of the cooker base 2 at the top. The canopy 8, the airflow guide plate 10, and the back plate 9 are integrated to form a hood. A grease filter 4 for collecting oil and fat contained in oil smoke by passing oil smoke generated during cooking through the suction port 3 is provided with a canopy 8
It was installed using the airflow shielding plate 14. The airflow shielding plate 14 prevents the combustion air of the cooking device 1 from being directly sucked into the ventilation passage 11 and improves the combustion efficiency of the cooking device 1.

In addition, the suction port 3 is connected to a blower 12 mounted inside the cooker base 2 via a ventilation passage 11, and an exhaust duct 13
It communicates with the outside through. In the above structure, when the blower 12 is operated, oil smoke, odor, etc. generated during cooking are sucked from the front of the cooker base 2 and guided to the airflow flowing along the airflow guide plate 10 and the canopy 8 toward the suction port 3. After passing through the grease filter 4, it is sucked from the suction port 3, passes through the ventilation passage 11 and the exhaust duct 13, and is discharged to the outside. The oil and fat contained in the oil smoke adhered when the oil smoke passed through the grease filter 4.

Problems to be Solved by the Invention In such a conventional configuration, when the amount of oil and fat adhered to the grease filter 4 increases, the adhered oil and fat gradually accumulates at the lower end portion of the grease filter 4, and finally the air flow shielding plate 14 is covered. There is a problem that the air flow shield plate 14 and the upper surface of the cooker table 2 are soiled by being drooped and accumulated on the upper surface of the cooker table 2.

The present invention solves such a problem, and an object of the present invention is to provide a clean cooking exhaust device in which the oil collected by the grease filter does not stain the upper surfaces of the airflow shielding plate and the cooker table. Is.

Means for Solving the Problem In order to solve this problem, the present invention provides a suction port at the upper rear part of a cooker table with a cooker arranged on the upper surface, and extends from the rear of the cooker table at the lower part of this suction port. Installed so that the lower tip of the grease filter provided between the airflow shield plate and the canopy provided to cover the cooker above the cooker table is located on the side opposite the cooker side of the airflow shield plate, An oil groove is provided on the anti-cooker side of the airflow shield plate, the tip of which penetrates the airflow shield plate and reaches an oil reservoir detachably provided on the upper part of the cooker table.

Action With this configuration, the oil and fat accumulated in the lower part of the grease filter drips down into the oil groove provided on the side opposite the cooker of the airflow shield plate,
After flowing in the oil groove, it penetrates the airflow shielding plate at the tip and accumulates in the oil sump placed on the top of the cooker table.

Embodiment An embodiment of the present invention will be described below with reference to FIGS. 1 and 2. In the present embodiment, the rectangular grease filter 4 is attached so that the lower end portion thereof is located on the side opposite to the cooker side of the airflow shield plate 7, and a U-shaped oil groove 5 is formed in the lower portion thereof by using the airflow shield plate 7. It is attached. The oil groove 5 is inclined to the left and right with respect to the central portion, and its tip portion penetrates the airflow shield plate 7 from the side opposite the cooking device to the cooking device side, and the airflow is formed at the left and right rear portions of the upper surface of the cooking device base 2. Guide plate 10 and airflow shield plate 7
It is located above the oil sump 6, which is a triangular prism-shaped container that is detachably placed so as to come into contact with. Other configurations are the same as the conventional example, and detailed description thereof will be omitted.

In the above configuration, when a large amount of oil and fat adheres to the grease filter 4 and accumulates in the lower portion, it drops as oil drops into the oil groove 5 on the side opposite to the cooker. The dripping oil flows to the left and right along the inclination of the oil groove 5, penetrates to the cooker side at the tip, and flows down to the oil sumps 6 placed on the left and right. Since the oil sump 6 is detachably installed, it is not necessary to replace the oil sump 6 by discarding only the oil when the oil is full.

In this embodiment, the oil groove is inclined from the center to the left and right, and two oil sumps are provided. However, the oil groove may be inclined from the left end to the right end or from the right end to the left end. It will be one.

EFFECTS OF THE INVENTION As described above, according to the present invention, the lower end of the grease filter is installed so as to be located on the side opposite to the cooker side of the airflow shield plate, and the tip at the lower portion thereof penetrates the airflow shield plate on the cooker side. Since an oil groove is provided so that the oil dripping from the grease filter will collect in the oil sump that is detachably installed on the cooker side, the oil collected by the grease filter
The airflow shield plate and the top surface of the cooker stand will not get dirty, and the oil accumulated in the oil sump can be easily discarded, and only the tip of the oil groove will be located on the cooker side of the airflow shield plate. The oil groove does not hinder the wiping operation, the oil adhering to the airflow shielding plate can be easily wiped off by cooking, and a clean exhaust device for cooking can be provided.
