Abstract

PURPOSE:To enable entire ventilation to be performed without decreasing a cleaning characteristic with a more simple structure by a method wherein the top surface of an ornamental panel is inclined toward a main body of a range hood until it may abut against it and a sub-suction port is arranged above the abutting position. CONSTITUTION:Waste gas or soot generated from a cooking burner 9 ascends as an ascending air flow (a) and sucked into a main body 1 of a range hood from a main suction port 4 by a fan 3. However, in case an air speed of the ascending air flow (a) is more superior than a sucking air speed of a fan 7, the ascending air flow (a) ascends along an inner surface of an ornamental panel 2 without being directly sucked into a fan 7. To the contrary, since the top surface 5 of the ornamental panel inclined from the upper part of the ornamental panel 2 downwardly toward the main body 1 and abutted there closes the upper part of the ornamental panel 2, the ascending air flow (a) is sucked again into the main body 1. Waste gas or soot staying near the top surface is sucked from a sub-suction port 6 above an abutting position of the main body 1 and the top surface 5 along the shield plate 3.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a range hood having a sub-intake port for discharging oil smoke and waste gas generated in a kitchen to the outside, and particularly for effectively ventilating the whole.

Conventional technology Generally, range hoods are provided with a through hole at the top of the range hood body for general ventilation, which serves as an auxiliary suction port.
If the wind speed of the rising air containing oil smoke is higher than the suction wind speed near the auxiliary suction port, the rising air that was once sucked into the range hood body from the main suction port will flow out of the range hood body again from the auxiliary suction port. Sometimes it comes out. Therefore, a reliable sub-suction means for general ventilation has been desired.

For this reason, conventional range hoods are, for example, as shown in FIGS. 6 and 7, which are mounted on a wall 8, house a fan 7 inside, and have a box body with open bottom and front sides. A main body 101 and a decorative panel 102 that is engaged with the curved surface of the range hood main body 101 and forms a main suction port 104 on the lower surface together with the range hood main body 101.
The interior of the decorative panel 102 attached to the inside of the decorative panel 102 is slowed down by a sub-intake port 110 provided as a through hole at the upper front surface of the decorative panel 102 and a slightly lower part of the sub-intake port 110. It consisted of a partition plate 111 that closes, and a curtain plate 3 that is attached between the range hood main body 101 and the ceiling surface.

Problems to be Solved by the Invention In the above-mentioned conventional range hood, if the wind speed of the rising air containing oil smoke sucked in from the main suction port is higher than the suction wind speed of the fan, the rising air is returned to the range from the sub-suction port. A partition plate is provided inside the decorative panel to prevent it from coming out of the hood body, but when cleaning the decorative panel, it is sometimes difficult to attach and remove it due to the heavy weight of the entire decorative panel. In addition, the presence of the partition plate makes the inside of the decorative panel complicated, making it troublesome to sweep away dirt and reducing cleaning performance.

The present invention has been made in consideration of the above-mentioned conventional problems, and an object of the present invention is to perform general ventilation using a sub-suction port with a simple structure without reducing cleaning performance.

Means for Solving the Problems In order to achieve the above object, the present invention includes a range hood main body that houses a fan and has an open bottom and front surface, and a range hood main body that is locked to the 011 side of the range hood main body and that is attached to the bottom surface together with the range hood main body. A through hole is formed in the upper front of the range hood body so that a through hole is formed above the contact point between the decorative panel that forms the main suction port and the top surface of the decorative panel that slopes downward toward the range hood body at the top of the decorative panel. It is equipped with an auxiliary suction port.

Effect With the above configuration, smoke and waste gas floating near the ceiling of the kitchen room are sucked into the range hood main body through the sub-intake port, and the wind speed of the rising air sucked in through the main suction port is higher than the suction wind speed of the fan. Even if there is a microwave oven, the rising air will rise along the inner surface of the decorative panel, but will be blocked by the top surface of the decorative panel, allowing complete ventilation without flowing back to the outside of the range hood body through the auxiliary suction port.

EXAMPLE An example of the present invention will be described below with reference to FIGS. 1 to 4. In the figure, 1 is the range hood body, and there are 7 inside.
The stove 7 is housed therein, has an open bottom and front surface, and is attached to a wall surface 8 so as to be located above the stove 9.

A decorative panel 2 is fixed to the front surface of the range hood body 1, and the range hood body 1 and the decorative panel 2 form a main suction port on the lower surface, and between the top surface of the range hood body 1 and the ceiling surface. A curtain plate 3 is attached to block off the space above the range hood body 1 and the indoor space. 5 is the top surface of the decorative panel, which is inclined from the top of the decorative panel 2 until it abuts downwards toward the range hood main body 1, and above this abutting position, the through hole and the range hood main body 1 are connected to each other. A sub suction port 6 is provided at the upper front surface.

In the above configuration, as shown in FIGS. 1 and 2, the waste gas and oil smoke generated from the stove 9 rises as an upward airflow a, and flows into the range hood main body 1 from the main suction port 4 through the 71 inlet 3. It gets sucked in. However, if the wind speed of the rising airflow a is higher than the suction wind speed of the fan 7, the rising airflow a will not be directly sucked into the fan 7 and the decorative panel 2
It rises along the inner surface of. However, since the decorative panel top surface 6 blocks the upper part of the decorative panel 2, the rising air current a is sucked into the range hood main body 1 again.

Further, waste gas and oil smoke near the ceiling surface are sucked into the range hood main body 1 through the sub-intake port 6 along the curtain plate 3.

As described above, according to this embodiment, the top surface 5 of the decorative panel is inclined toward the range hood main body 1 until it abuts downward, and the front surface of the range hood main body 1 is formed such that a through hole is formed above this abutting position. By providing the auxiliary suction port 6 in the upper part, ventilation can be achieved as a whole, and it is possible to prevent the rising air current d sucked in from the main suction port 4 from flowing back to the outside of the range hood main body 1 through the auxiliary suction port 6.

Effects of the Invention As is clear from the description of the embodiments above, according to the present invention, there is a decorative panel that is fixed to the front surface of the range hood main body and forms a main suction port on the lower surface together with the range hood main body, and a microwave The auxiliary suction port is provided at the top of the front of the range hood body so that it forms a through hole above the contact point with the top surface of the decorative panel that slopes downward toward the hood body, making it easy to clean. The effect is that the whole body can be ventilated without reducing the performance.
