Abstract

PURPOSE:To obtain the subject ventilator with a low noise and an excellent collection effi ciency by a method wherein the top end of a hollow wall member, which extends in a direction substantially parallel to a heat-cooking apparatus and in an inverted L-shape, has an upper air suction port opened downwardly, and a wall member extending upwardly is provided on the upper surface of rise part on right and left sides, and then a suction port and the upper suction port are made to communicate to a blower for exhaust via a duct. CONSTITUTION:The top end of a hollow wall member 4 forms an eaves-shaped overhang extending toward a cooking apparatus 1, where an upper air suction port 5 opened downwardly is provided. Further, an air current guide plate 8 with bent part 8A on the right and left side of said plate 8, the top ends of the bent part 8A being bent toward the cooking apparatus 1 so as to surround an air suction port 3, is provided. Both the suction port 3 and the upper suction port 5 communicate to an exhausting blower 7 through a duct 6. When the exhausting blower 7 is operated, negative pressure arises in the vicinity of the suction port 3 and the upper suction port 5, and oil vapor, smoke, odor and the like generated on the cooking apparatus 1 pass through the duct 6 from the suction port 3 and is discharged outdoors. On the other hand, smoke and the like which tend to rise upwardly are sucked into the upper suction port 5 along an air current guide plate 4A and the air current guide plate 8 and then are discharged outdoors. In this instance, the bent part 8A of the air current guide plate 8 guide the current ascending along side plate 8 to the upper suction port 5.

Description

[Detailed description of the invention] Industrial applications 2 to 1/ The present invention is aimed at reducing the amount of oil generated by heating cookers in the kitchen.

This relates to kitchen ventilation equipment that exhausts smoke, odors, etc.

BACKGROUND OF THE INVENTION Conventionally, this type of kitchen ventilation system has been constructed as shown in FIGS. 3 and 4. In the case of FIG. 3, an intake port 102 is provided at the rear of two sides of a cooking device 101 such as a gas stove, and is connected to a blower 104 installed inside a cooking table 103 through a duct 105. Furthermore, a canopy 106 is attached above the air intake port 102, which is similar to a canopy 106 on which a cooking device is placed. In the above configuration, oil, smoke, odor, etc. generated during cooking are sucked from the intake port 102 along the canopy 106 by operating the blower 104.
Discharged outdoors.

In the case of FIG. 4, an intake port 108 is provided in the center of a cooking device 107 such as a gas stove, and is connected to a blower 110 installed inside a cooking table 109 via a duct 111. In the second configuration, oil, smoke, odor, etc. generated during cooking are sucked through the air intake port 108 by operating the blower 3/\7110 and discharged outdoors.

Problems to be Solved by the Invention In the conventional kitchen ventilation system as described above, in the case shown in FIG. air volume is required, which increases the noise level.

There was also the problem that a canopy was required to catch smoke and the like that tried to escape upwards. Also, in the case of Figure 4, the noise was similar to that of Figure 3, and there was a problem that the smoke that was trying to escape further upwards could not be completely captured, and most of it leaked out. .

The present invention solves these conventional problems, and aims to provide a kitchen ventilation system with low noise and excellent collection efficiency.

No Means to Solve the Problem In order to solve this problem, the present invention has been added to the top! (
A rising portion is provided at the rear of the upper surface of the cooking table on which the cooking device is placed, and on the left and right sides of the upper surface, and an air intake port is opened on the side of the heating cooking device of this raised portion.
A hollow wall body extending obliquely upward in the direction of the front of the cooking table is provided on the - side, and the second part of the hollow wall body extends in an inverted shape almost horizontally toward the heating air conditioner side, and has an air intake port opening downward. A wall body extending upward is provided on the upper surface of the left and right vertical two parts, and the intake port and the upper intake port are connected to an exhaust air blower through a duct of a kitchen ventilation system. It is structured as follows.

With this configuration, when air is sucked in from the intake port by the exhaust blower, a descending airflow is generated in the space north of the cooking equipment, and this descending airflow causes oily smoke and odors generated during cooking to flow outside from the intake port without rising up. It is discharged. Even if smoke rises upward at this time, it is collected from the "two-part intake l" at the upper end of the rear hollow wall. In addition, the walls on the two sides of the left and right rising sections block the effects of turbulent airflow in the room, so smoke and odors from cooking can be efficiently collected with a small amount of airflow.

EXAMPLE Hereinafter, a kitchen ventilation system according to an example of the present invention will be explained with reference to the drawings. As shown in FIGS. 1 and 2, an intake port 3 is provided at the rear of the upper surface of the cooking table 2 on which the cooking appliance 1 is placed and at the left and right rising portions 2a, and the cooking appliance 1 is provided above the rear intake opening.
A hollow wall body 4 is provided with an airflow guiding plate 4A whose side wall surface is inclined toward the rear, and the second part of the hollow wall body 4 is provided with an upper air intake port 5 that extends toward the cooking appliance 1 side in the form of an eave and opens toward the bottom surface. has been established. Air flow guiding plates 8 are provided with bent portions 8A whose upper ends are bent toward the cooking appliance 1 side on the left and right sides so as to surround the intake port 3.
has been established. Both the intake port 3 and the upper intake port 5 are connected to an exhaust blower γ by a duct 6.

When the exhaust blower 7 is operated in the above configuration, there is no negative pressure in the vicinity of the intake port 3 and the upper intake port 6, and oil, smoke, odor, etc. generated on the cooking appliance 1 are discharged from the intake port 3 to the duct l-
6 and is discharged outdoors.

-4 Smoke, etc. that tries to rise to one side is sucked into the intake port 5 along the airflow guide plate 4A and the airflow guide plate 8,
It is discharged outdoors. At this time, the bent portion 8A of the airflow guiding plate 8 guides the airflow rising along the airflow guiding plate 8 to the two-part intake air []5.

Effects of the Invention As is clear from the above description of the embodiments, according to the present invention, intake ports are provided on the outer periphery of the second part of the cooking table and on the rear side thereof, and the second part opens downward. By surrounding the cooking table with a wall, the air above the cooking table is sucked in as a wide flow from the front of the cooking table to the rear, so oil smoke etc. generated on the cooking table can be efficiently collected with low noise, and cooking There is always a flow of fresh air around the cook standing in front of the counter, ensuring comfort and safety, and there is no need for a hood or exhaust duct above the counter, so there are no restrictions on installing hanging cabinets, etc. This allows for effective use of kitchen space.
