Abstract

PURPOSE:To facilitate the removal work of a front hood on the front surface of a range hood body by joinning a coupling surface of the range hood on the side of a body and a joint surface of the same on the side of the front hood through stopper means each provided on the respective surfaces. CONSTITUTION:Upon a front hood 15 being mounted on a range hood body 3, a spring 13 provided on a second joint surface 12 is engaged from the front surface side of the range hood body 3 with an engagement hole 5 formed on a first joint surface 4 of the range hood body 3 and with a roller catch 6 as a fixed part. Then, there are superimposed a mounting hole 17 formed on the first joint surface 4 and a tapped mounting hole 18 formed on the second joint surface 12 to fix both members 3, 5 through threading of a screw 16. Further, upon the range hood being cleaned, the screw 16 is removed and the front hood 15 is pulled frontward, whereby a leaf spring 13 is separated from the roller catch 6 against the retaining force of the roller catch 6.

Description

[Detailed description of the invention]

0001

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a range hood that discharges oil smoke, waste gas, etc. generated during cooking to the outside.

0002

[Prior Art] In recent years, this type of range hood has been constructed in such a way that the front hood can be easily attached and detached in order to clean the air blower built into the range hood, which has become extremely dirty due to oily smoke generated during cooking. Something was requested. For this reason, conventional range hoods generally include a range hood main body 25 that is attached to a wall surface 21, houses a casing 23 to surround a fan 22, and has a suction port 24 opened at the bottom, as shown in FIG. , a filter 26 that is disposed near the suction port 24 inside this range hood body 25 to collect oil dust in oil smoke, and a filter 26 that is detachably attached to the front of the range hood body 25 with a hook and a fixing screw (not shown). It consisted of a front hood 27 and an adapter 29 attached to the top of the range hood main body 25 and connected to an exhaust duct 28.

[0003] In the above configuration, when the fan 22 is operated during cooking in the gas range 30, the generated oily smoke flows through the suction port 2 between the front hood 27 and the range hood main body 25.
4, passes through a filter 26, and exits through an exhaust duct 28.
It was used to efficiently collect oil smoke by exhausting it outside the room.

[Problems to be Solved by the Invention] In such a conventional range hood structure, the front hood 27 is hooked from above onto two hooks provided on the left and right sides of the upper part of the range hood main body 25. Because it is fixed with fixing screws (not shown) provided on the lower left and right sides of the front hood 27, depending on the construction location, there may not be enough space on the ceiling surface to hang the front hood 27 from above, making it impossible to install the front hood 27. There were other problems.

[0005] The present invention solves these conventional problems and aims to provide a range hood with improved workability and maintainability.

[0006]

[Means for Solving the Problems] In order to achieve the above object, the range hood of the present invention is mounted on a wall so as to be located above a combustion cooking appliance such as a gas range, and has an opening on the front side and a first opening on the bottom side. A suction port has an air blower therein, a first joint surface is formed around the front opening, an engaging hole and a fixing part are provided on the left and right sides above the first joint surface, and further the first joint surface It has a range hood main body with screws and mounting holes on the left and right sides of the bottom, a second suction port on the bottom surface, an opening on the back surface, a second joint surface formed around the back opening, and a second joint surface formed around the back opening. A leaf spring that engages with the engagement hole provided in the range hood body and the fixing part is provided on the left and right above the second joint surface, and a screw hole that overlaps with the mounting hole is provided on the left and right below the second joint surface. The plate spring is engaged with the engagement hole and the fixing part, the mounting hole and the screw hole are overlapped, and the front hood is removably connected to the range hood main body by the screw.

[0007]

[Operation] The range hood of the present invention has the above-described structure, and the first joint surface of the range hood main body and the second joint surface of the front hood are joined by locking means provided respectively, so that the front hood can be attached and detached from the range hood. This can be done on the front of the main body.

As a result, even when the hood body is installed near the ceiling surface, it can be easily attached and detached.

[0009]

DESCRIPTION OF THE PREFERRED EMBODIMENTS A range hood according to an embodiment of the present invention will be described below with reference to FIGS. 1 to 4. As shown in the figure, a first suction port 1 is formed by attaching to a wall surface A, and a first suction port 1 is formed by opening the front and bottom surfaces, and a first suction port 1 is formed around the front opening of the gingi hood main body 3, which has a discharge port 2 provided on the top surface. A joint surface 4 is formed. A rectangular engagement hole 5 is provided above the range hood body 3, and a fixing portion consisting of a roller catch 6 is provided at the back of the engagement hole 5.
The lower part has a screw 16 and an attachment hole 17 for attaching it. A blower 8 is provided inside the range hood main body 3,
A filter 10 is provided in an air flow path 9 formed between the first suction port 1 and the blower 8. The opening on the front side of the range hood body 3 is covered and the lower surface has a second suction port 11, and around the back opening there is a second joint that is joined to the first joint surface 4 formed on the range hood body 3. There is a front hood 15 forming a surface 12. This front hood 15 is provided with a leaf spring 13 having a hollow tip at the tip that enters the engagement hole 5 formed in the first joint surface 4 and engages with the roller catch 6 above the second joint surface 12. A mounting screw hole 18 is provided below the joint surface 12 and overlaps with the mounting hole 17 formed in the first joint surface 4 .

When the front hood 15 is attached to the range hood main body 3 in the above structure, the spring 13 provided on the second joint surface 12 is inserted between the engagement hole 5 formed on the first joint surface 4 of the range hood main body 3 and the roller catch 6. The range is engaged from the front side of the range hood main body 3, and then the mounting holes 17 formed on the first joint surface 4 and the tapped mounting holes 18 formed on the second joint surface 12 are overlapped and fixed with thumbscrews 16. A front hood 15 is attached to a hood body 3. Also, when cleaning the range hood, remove the screws 16 and pull the front hood 15 forward.
The elasticity of the leaf spring 13 resists the holding force of the roller catch 6, so that the leaf spring 13 separates from the roller catch 6, and the front hood 15 is removed from the range hood main body 3, making it possible to clean the inside.

[0011]

Effects of the Invention As is clear from the description of the embodiments above, according to the range hood of the present invention, an engagement hole and a roller catch are provided on the first joint surface provided at the front opening of the range hood main body. A second joint surface provided at the rear opening of the front hood is provided with a tapped screw hole that overlaps with the mounting hole of the first joint surface and the plate spring that engages with the engagement hole and the roller catch, so that the front hood and the range Since the hood body is connected with screws, the front hood can be attached and detached from the front of the range load body, so even when the range hood body is installed near the ceiling, the front hood can be easily attached and detached. , it is possible to provide a range hood with improved workability and maintainability.
