Description

[Detailed Description of the Invention] This invention relates to an exhaust system for a kitchen, which is disposed above a heating appliance, in order to discharge contaminated air rising due to the use of the heating appliance, such as a range, a gas stove, or a stove, to the outside.

Conventionally, various structures and designs have been known for ventilation devices for indoor rooms that are installed above heating appliances and discharge the rising contaminated air to the outside. A hood for collecting the air, an exhaust fan, its drive means, duct means, and a box-shaped casing to house it are essential, and the lower part of the single casing is the hood, and the exhaust fan and The most common structure was that the drive means was provided and a duct was connected to the discharge port of the exhaust fan.

However, in the conventional exhaust system for a room, all parts and mechanisms including the hood are arranged in a single casing, and the duct must also be connected inside this casing. Connection work and cleaning of various parts and mechanisms including the hood were extremely difficult.
Furthermore, since it is constructed as a single piece and has a considerable weight, it is inconvenient to attach and remove it from the building frame, making it difficult for one person to work on it.

This invention was devised to eliminate the above-mentioned drawbacks found in conventional room exhaust systems, and will be described in detail below with reference to the drawings.

The exhaust device for a room according to this invention is constructed by separating the device into three parts, and the three parts are removably connected to each other to facilitate assembly and disassembly.
It is characterized by convenient manufacturing, cleaning, installation, transportation, and inventory. Referring to FIGS. 1 and 2, the kitchen exhaust system according to the invention includes a first member 1 having a hood function suitable for efficiently collecting contaminated air rising from below; 1
a second member 2 having a passage for guiding the contaminated air collected in the third member 3; It consists of a third member 3.

The first member 1 is configured as a box-shaped hood member with an open top and bottom, and has a lower opening 1 with its front side extending forward in order to improve the efficiency of collecting contaminated air.
The area of 0 is increased. The upper opening 11 communicates with the second member. On the front side, there is a hole 12 that exposes electrical control buttons attached to the third member.
is formed (Figure 3).

Referring to FIGS. 4 and 5, the second member 2 is formed into a rectangular box with an open bottom surface, and the bottom opening 20 communicates with the top opening 11 of the first member 1. A filter 2 is installed adjacent to and slightly above the lower opening 20.

serves also as a partition plate that can close the front surface of the third member 3, and has a communication hole 24 that communicates with the third member 3. Connecting fittings 25 and 26 for connecting to the third member 3 are attached to the upper and lower portions of the back plate 23. Although the shape and structure of the connecting fittings 25 and 26 are not particularly limited, in the illustrated embodiment, the upper connecting fitting 25 has a hooking structure that is hooked to the corresponding connecting fitting of the third member 3. The lower connecting fitting 26 is made of a plate-shaped member suitable for connection with the fitting of the corresponding third member 3 with screws.

Inside the second member 2, there is a lower opening 2 as needed.
A switching damper may be provided that can selectively switch between intake from both the 0 and upper intake holes 22 and intake from only one of them. The filter 21 is preferably a filter that can filter out oil and fat from contaminated air, and by using such a filter, oil and fat can be removed from the air blower and duct installed in the third member 3. This will prevent oil from sticking to the air blower and prevent duct fires.

Referring to FIGS. 6 and 7, the third member 3 is formed into a rectangular box with an open front, and is partitioned into two left and right chambers 31 and 32 by a partition wall 30 located approximately in the center. . The first chamber 31 is located in alignment with the communication hole 24 formed on the back surface of the second member 2, and a blower fan 33 is disposed therein. The blower fan 33 is driven by a motor 34 located at the back thereof. A discharge port 35 of the blower fan 33 is formed in the field wall 30. The second chamber 32 is used as a connection space for connecting a duct 36 to the discharge port 35 for discharging contaminated air to the outside.

When the second member 2 and the third member 3 are joined, the back plate 23 of the second member 2 is positioned as a partition plate, and the open front surface of the third member 3 is Obstruction. Therefore, the second
The duct connection work within the chamber 32 can be performed from the front of the third member 3, and the work is extremely simple. Furthermore, cleaning of the blower mechanism parts including the blower fan can be done from the front as well, making the work easier.

A space for arranging the motor 34 is provided by a partition wall 3.
If 7 is separated from the first chamber 31 that houses the blower fan 33, electrical parts including the motor 34 can be stored.
It can be isolated from the flow path of contaminated air, and contamination of these electrical components can be prevented.

Attachment fittings 38 and 39 to the building frame are attached to the back surface of the third member 3. Mounting bracket 38, 3
9 may have any structure, but for the simplest installation work, the upper mounting bracket 38 is a latching bracket that is hooked to a receiving bracket 40 of the corresponding building frame, and the lower mounting bracket 39 is a latching bracket that is hooked to a receiving bracket 40 of a corresponding building frame. Constructed into a plate member suitable for screwing to the building frame. Further, a receiving metal fitting 41 corresponding to the mounting metal fitting 25 of the second member 2 is attached to the upper front surface, and a mounting metal fitting 42 corresponding to the mounting metal fitting 26 of the second member 2 is attached to the lower front surface.

Reference numeral 43 denotes a switch control box mounting plate extending obliquely forward from the lower front surface, and a switch control box 44 is disposed at the tip, and the switch button 45 of the box 44 is inserted into the hole in the front surface of the first member 1. Protrudes from 12. 46
is a lighting box hung vertically from the bottom,
through the upper opening 11 of the first member 1
It extends into the member 1 of.

Next, install the kitchen exhaust system as shown in Figures 8 to 1.
Figure 0 will be explained. First, as shown in FIG. 8, the third member 3 is attached to a building frame, for example, a wall 5. In this case, the easiest way is to hook the mounting bracket 38 on the upper part of the back to the bracket 40 fixed to the wall 5,
Fix the lower mounting bracket 39 to the wall 5 with screws.
Since the third member 3 is not attached to the entire exhaust system, it is light in weight and can be carried out by one person. After fixing the third member 3 to the wall 5, the duct 3
6 is connected to the discharge port 35.

Next, as shown in FIG. 9, the mounting bracket 25 of the second member 2 is hooked to the receiving bracket 41 of the third member 3,
The lower mounting brackets 26 and 42 are removably connected with thumbscrews 6 to join the second member 2 to the third member 3. By such joining, the open front surface of the third member 3 is closed by the back plate 23 of the second member 2, and the communication hole 24 is connected to the air intake port of the blower fan 33.
are aligned and communicated within the second member 2.

Next, as shown in FIG.
The first, second, and third members 1, 2, and 3 are detachably connected to each other.

As described above, according to this invention, the cubicle exhaust system is made up of three members 1, 2, and 3 that can be separated from each other.
Since the exhaust system is divided into parts and joined together during installation, when installing the exhaust system on the building frame, it is only necessary to handle each component, which is relatively light in weight, one after the other, making it easy for one person to do the installation work, and reducing the risk of contamination. Cleaning work can also be done easily. Further, even when manufacturing, transporting, and stocking products, each member 1, 2, and 3 can be separated and carried out separately, which improves workability and convenience. In addition, the front surface of the third member on which the blower fan is installed is open so that the duct can be attached to the fan from the front of the third member, making the duct installation extremely easy. In addition, since the second member is connected to the front surface of the third member, the front surface of the third member can be closed with the back plate of the second member,
There is an advantage that no special structure is required for closing the front surface of the third member.
