つた。 Conventional ventilation systems, for example, install an inverted hopper-type ceiling frame in the shape of a pyramid on the ceiling above a deep fryer, and have the tip of a chimney connected to the center of this ceiling frame protrude outside. exhaust gas containing oil or steam. In this way, the exhaust action is carried out solely by the rising air of combustion gas or by a ventilation fan, which has the disadvantage of poor exhaust effectiveness. In addition, condensation adhering to the walls of this ceiling frame sometimes fell and stained the room. Furthermore, since such exhaust devices do not have a ventilation function, ventilation means such as opening a window to take in outside air are required.

Reference numeral 1 denotes a ceiling frame for collecting exhaust gas, which has a substantially quadrangular pyramid shape with a narrow upper part, and a storage section 2 is provided along the inside of the lower end of the ceiling frame. A cylinder 4 is connected to the center of the slanted wall surface 3 located above the ceiling frame, and the tip of the cylinder 4 protrudes outside the room to which an umbrella 5 is attached. Reference numeral 7 denotes an air supply pipe connected to the first blower 3 at its rear end, and is installed horizontally through the center of the lower end of the cylinder 4, with the tip of the cylinder 4 protruding outside the cylinder, and a sealing lid 19 is installed. Attach removably. In addition, when ventilation is performed at the same time as exhaust, a ventilation cover 9a having an opening 9b approximately half the cross-sectional area of the air pipe is attached, and half of the air in the air pipe is blown out from the opening 10. The remaining half is the ventilation lid 9
It is supplied into the room through the opening 9b of a. Furthermore, cylinder 4
An opening 10 is provided at the center of the lower surface of the air pipe 7 located inside the cylinder 4, and a concave reflective surface 11 is provided below the opening 10 by conically recessing the center of the upper surface of the cylinder 4. A reflector 12 is attached, and an annular suction port 15 is formed between the reflector 11 and the cylinder 4, and the reflector 12 has a plurality of connecting pieces 16,
16 is attached to the lower end of the cylinder 4.

増大させ、一層の排気効果を発揮する。 Therefore, when the outdoor air entering from the first blower 8 located outdoors is blown into the air pipe 7, if the tip is closed with the lid 9, the air pipe 7
The air inside blows out downward from the opening 10, and the air reflected by the concave reflective surface 12 rises along the reflective surface, passes through the suction port 15, and further rises along the side wall of the cylinder 4. . At this time, the annular suction port 15
This creates an ejector action in the ceiling frame 1, sucks the exhaust gas containing steam, etc. in the ceiling frame 1 into the cylinder 4, and enhances the evacuation effect. Further, since the air supplied from the second blower 20 is located above the suction port 15 and generates an upward airflow, the ejector action is increased and the exhaust effect is further improved.

If it comes into contact with the ceiling frame, the steam may condense on the inner wall of the ceiling frame and fall along the inner wall of the ceiling. Therefore, a storage chamber 2 is provided inside the lower part of the ceiling frame.
While it is stored inside, it vaporizes again and is discharged outdoors along with the exhaust gas. In addition, if there is a lot of dew condensation in the exhaust air, a rubber hose (not shown) may be connected to this storage chamber 2 to drain the water. Also, reflector 1
In order to prevent dew condensation on the lower surface of the reflector 1, an absorbent material 19 is attached to the entire lower surface of the reflector.

有する。 When supplying fresh air indoors, remove the lid 19 from the tip of the air pipe 7 and close the ventilation lid 9.
If a is installed, half of the air supplied from the first blower 8 will be blown out from the opening 10, and the remaining half will be able to supply fresh air into the room from the tip of the air pipe 7. Although the second blower 20 is used as the air source for the auxiliary air pipe 21, the tip of the air pipe 7 may be connected to the auxiliary air pipe 21. Furthermore, the air flow that is reflected by the reflector 11 and rises is divided into two by the air pipe 7, and when they recombine above the air pipe 7, turbulence is generated and the exhaust flow is It has the function of increasing the steam content and preventing dew condensation.

来る。 As described above, the present invention uses a blower to supply outdoor air indoors, and uses air from the same air supply source to suction exhaust air from within the ceiling frame by the ejector action. Therefore, one air source can be used for exhaust and ventilation at the same time, and furthermore,
It is possible to increase the ejector action by using the air supplied from the first blower or the second blower, and in addition, it can prevent water droplets from falling, so it should be installed above the source of steam etc. I can do it.
