Abstract

PURPOSE:To securely and effectively capture and exhaust, to the outside, gas involving smoke and odor produced from a burning appliance such as a range table in a kitchen without permitting the gas to be reflected back by a filter or to stay in an air stream reservoir of the lower part of hood, and hence keep indoor air clean in an exhaust hood structure which is disposed above the burning appliance so as to cover the burning appliance and which sucks and captures the gas including smoke and odor from the burning appliances with the actuation of an exhaust fan. CONSTITUTION:There are disposed on the same plane a filter 15 that covers an evacuation outlet 11a and an air flow control plate 16 disposed on the lower side from the foregoing filter 15 to introduce sucked gas to the filter 15. Further, the plane formed with those filter 15 and the air flow control plate 16 is located, traversing slantingly the direction of suction of the gas.

Description

[Detailed description of the invention]

0001

[Industrial Field of Application] The present invention is installed above a combustion appliance such as a stovetop in a kitchen, kitchen, etc. so as to cover the combustion appliance, and exhausts gas containing smoke, odor, etc. from the combustion appliance. This invention relates to an exhaust hood structure for sucking in, collecting, and guiding it to the outside as a fan operates.

0002

2. Description of the Related Art Conventionally, as shown in FIGS. 3 and 4, exhaust hoods 3 and 3 have been installed above combustion appliances (not shown) such as stoves in kitchens and kitchens to cover the combustion appliances. are installed protruding from the kitchen inner walls 7, 8, and by operating the exhaust fans 1, 4, gas containing smoke, odor, etc. generated by the combustion appliances is sucked into the exhaust hoods 3, 6 and flows outside. (For example, JP-A-60-175948, JP-A-63-41)
(See Publication No. 752).

[0003]The exhaust ports 3a and 6a of such exhaust hoods 3 and 6 are usually provided with filters 2 and 5, respectively. Here, in the exhaust hood 3 shown in FIG. 3, the filter 2 is provided from the kitchen inner wall 7 to the exhaust hood 3, and is arranged substantially perpendicular to the rising direction of the sucked gas. In addition, the exhaust hood 6 shown in FIG.
In this case, the filter 5 is disposed within the exhaust hood 6 in a substantially standing state.

0004

[Problems to be Solved by the Invention] However, in the exhaust hood structure shown in FIG. Due to the filter 2 disposed to obstruct the gas, the gas is repelled and spilled outside the exhaust hood 3, and the gas may not be reliably collected and discharged.

[0005] Furthermore, in the exhaust hood structure shown in FIG. 4, unlike the one in FIG. However, since there is a step between the exhaust hood 6 and the kitchen inner wall 8, an airflow pool will occur at the step, and gas will spill out of the exhaust hood 5, making it difficult to ensure that the gas is captured properly. In some cases, it was not possible to collect and discharge the waste.

[0006] The present invention is an attempt to solve such problems, and is intended to ensure that smoke and odor-containing gases emitted from combustion appliances are not repelled by the filter or stagnate in the airflow pool at the bottom of the hood. To provide an exhaust hood structure that can maintain indoor air in a clean state by efficiently collecting and exhausting the air to the outside.

[0007]

[Means for Solving the Problems] In order to achieve the above object, the exhaust hood structure of the present invention is disposed above a combustion appliance so as to cover the combustion appliance, and the exhaust hood structure is arranged above a combustion appliance to cover the combustion appliance, and the exhaust hood structure is arranged so as to cover the combustion appliance, and the exhaust hood structure is provided so as to cover the combustion appliance. In a device that collects gas and guides it to the outside, a filter that covers the exhaust port and an airflow control plate that is disposed below the filter to guide the sucked gas to the filter are arranged flush. At the same time, the surface formed by these filters and the airflow control plate is arranged diagonally across the gas suction direction.

[0008]

[Operation] In the exhaust hood structure of the present invention described above, the gases emitted by the combustion appliance rise upwards due to the operation of the exhaust fan, but at this time, the gases are flush with each other from the airflow control plate to the upper end of the filter. Along with being placed in
Since the surface is arranged diagonally across the gas suction direction, there is no airflow accumulation or airflow collision, and the gas rises smoothly while being guided by the airflow control plate.
It is efficiently collected and discharged to the outside.

[0009]

[Embodiment] Hereinafter, an exhaust hood structure as an embodiment of the present invention will be explained with reference to the drawings. Fig. 1 is a schematic vertical cross-sectional view thereof. In Fig. 1, numeral 11 is an exhaust hood; The hood 11 is provided above a stove (combustion appliance) 12 and protrudes toward the indoor side from the kitchen inner wall 13 so as to cover the stove 12.

Reference numeral 14 denotes an exhaust fan provided within the exhaust hood 11, and the exhaust fan 14 is located at an opening 13a formed in the kitchen inner wall 13 and communicating with the outside.

Furthermore, 15 is the exhaust port 1 of the exhaust hood 11.
A filter 16 covers the filter 1a, and a filter 16 is used to guide the gas sucked in by the exhaust fan 14 to the filter 15.
This is an airflow control board located below the

The filter 15 and the airflow control plate 16 are arranged flush with each other, and the surface formed by the filter 15 and the airflow control plate 16 is located on the back side of the stovetop 12 (on the kitchen inner wall 13 side). ) from the vicinity of the back guard 17 to the upper end of the filter 15 are arranged so as to diagonally cross the gas suction direction, that is, to rise from the kitchen inner wall 13 side toward the indoor side.

[0013] With the above-described configuration, gas containing smoke and odors generated by cooking on the stovetop 12 rises upward by the operation of the exhaust fan 14.

At this time, the filter 1 is removed from the airflow control plate 16.
These are arranged flush to the upper end of the kitchen wall 1, and the surface diagonally crosses the gas suction direction.
Since the gas is arranged so as to rise from the side 3 toward the indoor side, the sucked gas can flow through the airflow control plate 1 without creating an airflow pool or colliding with the exhaust hood 11 or the filter 15.
6, the gas collection efficiency is improved, and the gas discharge efficiency to the outside is also improved.

[0015] In this way, the gas from the stovetop 12 is
Because it is collected reliably and efficiently and discharged to the outside,
This allows indoor air to be kept clean at all times.

Furthermore, since the airflow control plate 16 stands up from the back side of the stovetop 12 from the indoor side, a cleaner can easily reach the airflow control plate 16 when cleaning dirt. At this time, by applying a stainless steel finish or the like to the airflow control plate 16, cleaning performance can be further improved.

Note that in the structure of this embodiment described above,
As shown in FIG.
8 may be provided. As a result, oil stains, etc. that adhere to the surface of the airflow control plate 16 and gradually flow down along the airflow control plate 16 can be received by the oil receiver 18, thereby preventing the top surface of the stovetop 12 from becoming dirty. can.

[0018]

Effects of the Invention As described in detail above, according to the exhaust hood structure of the present invention, the airflow control plate to the upper end of the filter are arranged flush, and the surface is oriented diagonally in the gas suction direction. Due to the extremely simple configuration of arranging them horizontally, the gas from the combustion appliances is guided by the airflow control board and rises smoothly without causing airflow pools or airflow collisions, and is efficiently collected and discharged to the outside. This has the effect of keeping the indoor air clean at all times.
