This application is based on and claims priority under 35 U.S.C. § 119(a) of a Japanese patent application number 2020-170703, filed on Oct. 8, 2020, in the Japanese Intellectual Property Office, and of a Korean patent application number 10-2021-0079646, filed on Jun. 18, 2021, in the Korean Intellectual Property Office, the disclosure of each of which is incorporated by reference herein in its entirety.
The disclosure relates to a ventilation hood.
A ventilation hood is provided above a heating cooker to ventilate heat, steam, oil vapor, odor, and the like (hereinafter, collectively referred to as smoke and the like) generated during cooking. However, in recent years, there is a case in which another cooker such as a microwave oven is disposed above the heating cooker in a kitchen.
As a ventilation hood in such a kitchen, there is a ventilation hood including an air suction port provided on a lower surface of a housing of the microwave oven and, for example, a fan provided in the housing to draw smoke and the like to the air suction port by operating the fan and exhaust the smoke and the like through the inside of the housing.
In this configuration, since it is necessary to maximize the space as a cooking chamber or secure a space for arranging control devices, etc., in the housing, an airflow path of smoke etc. becomes narrow so that it is difficult to obtain a sufficient suction air volume.
The suction air volume may be increased by increasing a fan speed, but as described above, because the airflow path in the housing is narrow, it is difficult to effectively increase the suction air volume, and other problems such as increased power consumption and noise occur.
On the other hand, in order to improve a collection efficiency of a ventilation hood, e.g., the ventilation hood shown and described in Japanese Patent Publication No. 2008-082634, a panel to form an airflow path between the lower surface of the housing and the panel may be provided.
However, when smoke and the like are generated just below the panel, the smoke and the like may be drawn into the airflow path between the panel and the lower surface of the housing, but for example, when a pot or the like is placed on a front side (in front) of the panel so that smoke and the like rise from the outside of the panel during cooking, a part of the smoke and the like is not collected and diffuses into a room, which deteriorates the comfort of an indoor environment.
The above information is presented as background information only to assist with an understanding of the disclosure. No determination has been made, and no assertion is made, as to whether any of the above might be applicable as prior art with regard to the disclosure.
Aspects of the disclosure are to address at least the above-mentioned problems and/or disadvantages and to provide at least the advantages described below. Accordingly, an aspect of the disclosure is to provide a ventilation hood, which is installed in a kitchen provided with a housing of a microwave oven or the like disposed above a heating cooker, capable of increasing a collection efficiency compared to the conventional art and collecting smoke and the like as much as possible.
Additional aspects will be set forth in part in the description which follows and, in part, will be apparent from the description, or may be learned by practice of the presented embodiments.
In accordance with an aspect of the disclosure, a ventilation hood is provided. The ventilation hood includes a housing provided above a heating cooker and having an air suction port on a lower surface thereof, a blowing fan provided in the housing to induce air to the air suction port, and a panel provided below the housing to form an airflow path between the lower surface of the housing and the panel, wherein the panel is arranged such that a negative pressure is generated in a front of an upstream opening of the airflow path by the operation of the blowing fan.
Herein, the expression “in front of an upstream opening” refers to a space being further from a forward side with respect to the upstream opening that is open toward the front side, and refers to a space being in further from a lateral side with respect to the upstream opening that is open toward the lateral side.
According to the ventilation hood configured as described above, because the panel is arranged such that a negative pressure is generated in front of the upstream opening of the airflow path, even when smoke and the like rise from the outside of the panel, the smoke and the like may be drawn into the airflow path by the negative pressure, so that even in the kitchen where the housing is provided above the heating cooker, smoke and the like may be collected as much as possible.
In order to generate a negative pressure for collecting smoke and the like as much as possible, it is suitable that a distance from an upper surface of the panel to the lower surface of the housing in a height direction is 100 mm or less, and particularly 50 mm or less.
Herein, specific experimental data will be described later.
When the panel is positioned in front of a front surface of the housing, the panel is disturbed in cooking.
Therefore, in order to generate negative pressure without disturbing cooking by the panel, in a configuration in which a front end of the panel is positioned in front of the front surface of the housing, it is suitable that a distance from the front surface of the housing to the front end of the panel in a front-rear direction is 100 mm or less.
With this configuration, the panel is not disturbed in cooking and a collection efficiency of smoke and the like may be increased.
In order to generate a negative pressure for collecting smoke and the like as much as possible, in a configuration in which the front end of the panel is positioned in the rear of the front surface of the housing, it is suitable that a distance from the front surface of the housing to the front end of the panel in the front-rear direction is 100 mm or less.
Herein, specific experimental data will be described later.
In order to prevent a finger of a user or the like from entering the upstream opening of the airflow path and to enable air suction, it is suitable that a grill having a grid shape is provided in the upstream opening of the airflow path.
It is suitable that the housing includes an air exhaust port to allow the air sucked from the air suction port to be discharged into a room, and a deodorizing part is provided in an internal airflow path to communicate the air suction port and the air exhaust port.
With this configuration, the comfort of an indoor environment is not deteriorated by the odor of smoke and the like, and the collected air may be circulated.
In addition, as another specific embodiment, a configuration in which the upstream opening of the airflow path is provided on the front surface of the housing may be exemplified.
As a more specific embodiment, a form in which the housing constitutes a cooker different from the heating cooker may be exemplified.
As a form in which the action and effect according to the disclosure are more remarkably exhibited, it is suitable that the cooker includes a touch panel provided on the housing.
With this configuration, deterioration of the operability of the touch panel may be prevented due to the effect of increasing the collection efficiency of smoke and the like by the disclosure.
In addition, as another form in which the action and effect according to the disclosure are more remarkably exhibited, the cooker having a voice recognition function may be exemplified.
With this configuration, because by the effect of increasing the collection efficiency of smoke and the like by the disclosure, for example, even when a small motor is used for the blowing fan or a rotation speed of the blowing fan is lowered, the smoke and the like may be collected as much as possible, noise may be reduced compared to the conventional art, so that the voice recognition function may be secured.
Other aspects, advantages, and salient features of the disclosure will become apparent to those skilled in the art from the following detailed description, which, taken in conjunction with the annexed drawings, discloses various embodiments of the disclosure.
The above and other aspects, features, and advantages of certain embodiments of the disclosure will be more apparent from the following description taken in conjunction with the accompanying drawings, of which:

Referring to
The panel 30 according to the embodiment is disposed such that a negative pressure is generated in front of the upstream opening La of the airflow path L as the blowing fan 20 operates.
The expression “in front of the upstream opening La” refers to a space being further from the front side with respect to the upstream opening La that is open toward the front side, and refers to a space being further from a lateral side with respect to the upstream opening La that is open toward the lateral side.
Referring to
The exhaust leakage improvement rate is a ratio between a leakage amount Zon at a front surface when the ventilation hood 100 is turned on and a leakage amount Zoff at the front surface when the ventilation hood 100 is turned off, and more specifically, is calculated by the following calculation formula.
Exhaust leakage improvement rate (%)=(1−Zon/Zoff)×100

As may be seen from the correlation of the graph referring to
For this reason, in the configuration of the embodiment in which the front end of the panel 30 is positioned in the rear of the front surface of the housing 10, the distance X is set to be 100 mm or less, and specifically, the distance X is set to 0 mm, that is, the front surface of the housing 10 and a front surface of the panel 30 are formed to be on the same plane. Accordingly, referring to
In the configuration in which the front end of the panel 30 is positioned in front of the front surface of the housing 10, when the distance X exceeds 100 mm, an exhaust leak occurs as described above, and furthermore, the panel 30 is obstructed in cooking. For this reason, in the configuration in which the front end of the panel 30 is positioned in front of the front surface of the housing 10, it is suitable that the distance X is 100 mm or less.
Referring to
As may be seen from this correlation, when the distance Y is 100 mm or more, the suction wind speed becomes the same as a suction wind speed when there is no panel, so it may be difficult to form a negative pressure. On the other hand, as the distance Y from the panel 30 decreases from 100 mm, the suction wind speed increases, so that a negative pressure is generated in front of the upstream opening La of the airflow path L.
Therefore, in the embodiment, the distance Y may be set to 100 mm or less, and may be 50 mm or less.
According to the ventilation hood 100 configured as described above, because the panel 30 is arranged such that a negative pressure is generated in front of the upstream opening La of the airflow path L, even when smoke and the like rise from the outside of the panel 30, the smoke and the like may be drawn into the airflow path L by the negative pressure, so that even in the kitchen where the housing 10 is provided above the heating cooker 101, smoke and the like may be collected as much as possible.
By setting the distance X from the front surface of the housing 10 to the front end of the panel 30 in the front-rear direction to −80 mm to 20 mm, as illustrated in
The disclosure is not limited to the above embodiment.
For example, in the ventilation hood 100 of the above embodiment, the distance X is 100 mm or less, and the distance Y is 100 mm or less, but in the ventilation hood 100 according to the disclosure, the distance X may be 100 mm or less, or the distance Y may be 100 mm or more.
In addition, although the above embodiment illustrates that smoke and the like are discharged to the outdoors, referring to
Referring to
As is apparent from the above, according to the disclosure, a ventilation hood, which is provided in a kitchen provided with a microwave oven and the like above a heating cooker, can increase a collection efficiency compared to the conventional art and collect smoke and the like as much as possible.
While the disclosure has been shown and described with reference to various embodiments thereof, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the disclosure as defined by the appended claims and their equivalents.
