Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a cooking device that has a cooking section equipped with or integrated with a cooking heater using electricity or gas as a heat source, and a smoke evacuation device. It is.

[Conventional technology]

The exhaust of contaminated air containing soot, smoke, steam, etc. in a kitchen during cooking is usually carried out by a ventilation fan or range hood installed above the cooking section. However, as is well known, with exhaust that relies on ventilation fans and range hoods, contaminated air flows along the wall behind the cooking section, so the wall behind the cooking section in the kitchen can become contaminated with oil smoke etc. very quickly. Moreover, it is difficult to prevent polluted air from spreading indoors using a normal ventilation fan. These problems can be solved by sucking and exhausting polluted air containing soot, smoke, steam, etc. immediately after it is generated. Cooking devices and the like have been developed. That is, as shown in FIGS. 10 and 11, the exhaust duct (1) is integrated into the stove, the suction port (2) of the exhaust duct (1) is brought close to the heating part (3) of the stove, and the exhaust gas is The polluted air sucked in by the blower (2) installed inside the duct (1) is exhausted to the outside. There is also a device as shown in Japanese Utility Model Application Laid-open No. 192117/1983 in which a smoke evacuation device consisting of an exhaust duct or the like is incorporated into a gas stand.

Conventional heating cooking devices with a smoke exhaust function basically suck the polluted air generated in a position close to the heating cooking part that performs boiling and exhaust it outside through an exhaust duct (1) etc. This prevents the diffusion of polluted air into the room and the resulting indoor pollution.

[Problem to be solved by the invention]

Conventional heating cooking devices such as those mentioned above exhaust the air outside, which requires construction work and is not easy to install.In addition, the functionality of existing exhaust devices such as ventilation fans that are widely installed in kitchens is limited. This includes issues that need to be resolved, such as the wastage of ventilation equipment and the creation of a chaotic kitchen situation in which various ventilation devices compete with each other.

This invention was made to solve the problem,
To provide a heating cooking device that is easy to install, can ventilate the kitchen including smoke by cooperating with an existing exhaust system, and can contribute to orderly ventilation of the kitchen.

[Means to solve the problem]

The heating cooking device according to the present invention includes a heating cooking table having a box-shaped platform structure having a heating cooking part on the upper surface on which a cooking heater is placed or integrally fixed, and an upper part behind the heating cooking part of this heating cooking table. It has a rear wall that stands up, and suctions polluted air containing oil smoke, smoke, steam, etc. generated during the use of the heating cooking section from a suction port located near the heating cooking section in front of the back wall, and then The device is equipped with a forced smoke evacuation device that applies pressure and blows out air from an air outlet provided at the top of the rear wall toward an existing exhaust device such as a ventilation fan installed above the heating cooking table. A rotatable and detachable air guide is provided above the suction port.

In addition, the front side of the rear wall provided with the suction port can be opened and closed.

In addition, the rear wall of the forced smoke evacuation device forms a barrier for the heating cooking section, and an oil guard made of transparent heat-resistant reinforced glass is provided.

[Effect]

In this invention, there is provided a heating cooking table having a box-shaped trapezoidal structure having a heating cooking part on the upper surface on which a heating device for cooking is placed or integrally fixed;
This heating cooking table has a rear wall that rises upward behind the heating cooking section, and the polluted air containing oil smoke, smoke, steam, etc. generated when the heating cooking section is used is removed from the heating cooking section in front of the rear wall. Suction is drawn through a suction port located at a certain location, and velocity and pressure are applied to the suction, which is then directed through an air outlet located at the top of the rear wall to an existing exhaust device such as a ventilation fan installed above the cooking table. Equipped with a forced smoke exhaust device that blows out,
By installing a rotatable and removable air guide above the intake port on the rear wall, you can simply adjust the positional relationship with the existing exhaust system and install it without doing any construction work for smoke exhaust. The polluted air containing smoke, smoke, steam, etc. that is generated during the use of the heating cooking section is suctioned into the suction port sequentially along with the air guide as it is generated, and then sent to the existing exhaust device such as a ventilation fan. It becomes possible to exhaust the air outside using the exhaust function.

Furthermore, since the front surface of the rear wall provided with the suction port can be opened and closed, objects can be easily inserted into and removed from the rear wall.

In addition, an oil guard made of transparent heat-resistant tempered glass is installed on the back wall of the forced smoke evacuation device to form a barrier for the cooking section, making it possible to visually see the smoke emitted from the cooking section. This prevents the spread of oil smoke.

Don't get too spoiled. This processing air is blown out with speed and pressure applied to it, so it is sent to the existing exhaust system (18a) which is operating without being diffused on the way. The existing exhaust device (18a) takes in the air directly from the forced smoke exhaust device (15) that is sent to the vicinity of its suction port and exhausts it to the outside of the room. That is, in the heating cooking device of this embodiment, the heating cooking section can be installed by simply adjusting the positional relationship with the existing exhaust device (18a) without having to install duct construction or exhaust type construction for smoke exhaust. In addition to generating polluted air containing oil smoke, smoke, steam, etc. during the use of (1),
It is possible to suction the air one after another and send it to an existing exhaust device (18a) such as a ventilation fan, and to cooperate with the existing exhaust device (18a) to effectively exhaust the air to the outside without impairing the exhaust function of the existing exhaust device (18a). In other words, it is easy to install, and by cooperating with existing exhaust devices (18a) such as ventilation fans widely installed in the kitchen, without wasting the function, orderly ventilation of the kitchen can be realized. In particular, since polluted air is sucked near the place where it is generated, insufficient polluted air can be treated with a small air volume, and stains on the walls around the cooking section of the kitchen can be significantly reduced. Furthermore, since the exhaust is not directly vented outdoors, there is an advantage that, for example, in the case of a tempura fire, the spread of fire can be prevented by taking fire prevention measures in the forced smoke exhaust system (15). Furthermore, the back wall (
Since all of the components including 36) are within the height range of the cooking work surface, maintenance such as cleaning is easy.
