Abstract

PURPOSE:To prevent an exhaust gas generated from a range table from flowing into a room by a method wherein an air curtain is blown from a blowing port located mode forwardly than a suction port of a range hood. CONSTITUTION:A range hood 3 is formed into an inverted L-shape at its side surface and it is placed while its vertical part being contacted with a wall 2. A horizontal part of the range hood 3 is provided with an air suction duct 4, an opening at a base end of the air supplying duct 4 is connected to an air supplying port 2b formed in the wall 2, and an opening port at an extreme end is connected to a blowing port 3c, formed at a lower surface of a horizontal part placed more forwardly than the suction port 3a. This air supplying duct 4 is widened at its extreme end so as to form a slit-like opening, so that the surrounding air sucked from the suction port 2b is blown out of the blowing port 3c, resulting in forming an air curtain. The air curtain is blown out from the blowing port to enable the exhaust gas generated from the range hood 1 to be prevented from flowing into a room, the exhaust gas generated at the range can positively be exhausted out of the room from a suction port 3a' through the exhaust duct 3b.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an exhaust device used for exhausting exhaust gas generated from a cooktop in a kitchen or the like to the outdoors.

[Conventional technology]

2. Description of the Related Art Conventionally, there is a structure shown in FIG. 8 that exhausts the exhaust gas generated from a cooktop having a plurality of cooktops arranged in the depth direction to the outside. In this structure, an exhaust pipe 33 with an intake port 32 formed at the upper end is provided on the back side of the cooktop 31, and an exhaust port 34 communicating with the exhaust pipe 33 is formed in a wall 35. Exhaust gas is sucked in through the intake port 32, passes through the exhaust pipe 33, and is exhausted from the exhaust port 34.

[Problem to be solved by the invention]

However, in this structure, the air supply port 32 can take in the exhaust gas generated from the range 31a on the side closer to the wall 35, but cannot take in the exhaust gas generated from the range 31b on the side farther from the wall 35. Exhaust air was rising indoors. As a result, there was a problem in that the interior of the room was contaminated by the exhaust gas.

Therefore, an object of the present invention is to provide an exhaust device that can exhaust all the exhaust gas generated in a cooktop to the outside.

(Means for Solving Problems) The exhaust system of the present invention includes a range hood that covers the upper and rear side of the range, an exhaust duct provided in the range hood and having an inlet facing the range, and an exhaust duct that covers the upper and rear sides of the range. and an air supply duct having a slit-shaped outlet that is provided at a position in front of the inlet of the hood and blows out an air curtain toward the front end of the range.

[For production]

According to the configuration of the present invention, by blowing out the air curtain from the outlet located in front of the inlet of the range hood, it is possible to prevent exhaust gas generated from the cooktop from flowing into the room. Therefore, 8. The exhaust gas produced in the microwave can be reliably discharged outdoors from the inlet through the exhaust duct.

〔Example〕

An embodiment of the present invention will be described based on FIGS. 1 to 6.

A cooktop l is installed along a wall 2.

An exhaust port 2a is formed in the wall 2 in alignment with the upper end of the cooktop 1, and an air supply port 2b is formed above the exhaust port 2a. However, the exhaust from the exhaust port 2a is transferred to the air supply port 2b.
These are placed laterally offset from each other to prevent inhalation of the air. Furthermore, fans 5 for blowing air outwardly and inwardly are installed at the exhaust port 2a and the air supply port 2b, respectively. A plurality of cooktops 1a are arranged in the depth direction on the upper surface of the cooktop 1.

The range hood 3 has an upside-down shape and is provided with its vertical portion in contact with the wall 2. A suction port 3a (FIG. 2) is formed from the front surface of the vertical portion to the horizontal portion, and this suction port 3a is covered with a breathable mesh material. The suction port 3a is an exhaust duct 3b formed in a vertical part.
The exhaust duct 3b communicates with the exhaust port 2a of the wall 2. An air supply duct 4 as shown in FIG. 6 is installed in the horizontal part of the range hood 3, and an opening on the base end side of the air supply duct 4 is connected to an air supply port 2b provided in the wall 2. The opening on the tip side is connected to an air outlet 3C formed on the horizontal lower surface in front of the inlet 3a. Moreover, since the air supply duct 4 becomes wider toward the tip and forms a slit-shaped opening, an air curtain is formed when the outside air sucked in from the air supply port 2b is blown out from the blow-off port 3C. This air supply duct 4 is made of a material such as stainless steel.

The exhaust operation according to this embodiment will be explained. During cooking, when the fans 5 of the exhaust port 2a and the air supply port 2b are operated before using the ranges la and lb, indoor air is discharged from the suction port 3a to the outdoors via the exhaust duct 3b. Also,
The outside air sucked in from the air supply port 2b is blown out from the air outlet 3C of the range hood 3 to form an air curtain. When the ranges la and lb are used in this state, the exhaust gas generated from the range 1a near the wall 2 is sucked into the suction port 3a as it is. In addition, the exhaust gas generated from the range 1b on the side far from the wall 2 is blocked by the air curtain and does not leak into the room, and after flowing to the range hood 3 side, it is sucked into the intake port 3a and passes through the exhaust duct 3b. and is discharged outdoors from the exhaust port 2a.

According to the configuration of this embodiment, since the outside air taken in from the air supply port 2b is blown out from the air outlet 3C of the range hood 3, an air curtain can be formed above the range hood 1, and the wall 2 It is possible to prevent the exhaust gas from the range 1b which is far away from flowing into the room. Therefore, the exhaust gas generated in the range table 1 can be reliably discharged outdoors. Moreover, since this range hood 3 is installed at a lower position than conventional ones, objects can be placed on the top surface of the range hood 3. Also, range hood 3
It is also possible to install a storage cabinet or the like in the space above.

Another embodiment of the invention is shown in FIG. In this example, a retractable exhaust guide 6 is provided above the air supply duct 4 of the range hood 3 of the previous embodiment. The exhaust guide 6 is made of transparent tempered glass or the like in the shape of an arc, and when projected forward, the tip is diagonally downward, guiding the exhaust toward the range hood 3 side. Further, the tip of the exhaust guide 6 has a hook-shaped handle for easy insertion and removal.

According to the configuration of this embodiment, the provision of the exhaust guide 6 makes it difficult to disturb the air curtain, so that the exhaust gas does not flow into the room, and the exhaust gas can be more reliably discharged to the outdoors. Other effects are the same as those of the previous embodiment.

In the second embodiment, the air curtain was formed only above the cooktop 1, but by forming air curtains on both sides as well, the air can be exhausted even more effectively.

〔Effect of the invention〕

According to the exhaust device of the present invention, by blowing out the air curtain from the outlet located in front of the inlet of the range hood, it is possible to prevent the exhaust gas generated from the range hood from flowing into the room.

Therefore, the exhaust gas generated in the microwave can be reliably discharged outdoors from the inlet through the exhaust duct.
