Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an exhaust device for a cooking device that effectively discharges steam or combustion exhaust gas generated during cooking in a range having a gas or electric stove to the outside.

Conventional exhaust systems of this type include: (a) A ventilation fan and a hood are installed on the rear wall above the stove; (b) An exhaust intake port is installed near the stove, and ventilation is installed on the rear wall through an exhaust duct. The most common method was to release it outdoors using a fan. However, the above-mentioned method a has disadvantages such as the noise from the ventilation fan easily entering the kitchen and the rear wall surface being easily soiled. In addition, with method b, especially those with four-burner stoves, there is a drawback that they do not have the ability to sufficiently exhaust steam, exhaust gas, etc. that are generated when boiling on a stove far from the exhaust air intake, which pollutes the air in the kitchen. Ta.

The present invention solves the above-mentioned drawbacks of the conventional methods, especially in method b, and allows the kitchen to be kept clean by reliably collecting steam, exhaust gas, etc. no matter which one of a plurality of stoves is used. The purpose is to make effective use of the space above.

The present invention stores and guides steam and exhaust gas generated from a stove into an exhaust duct using a removable air guide, and forcibly exhausts it outdoors.The exhaust gas from the built-in heating device is also sucked into the exhaust duct. This prevents the area around the stove from getting dirty and prevents the temperature of the appliance from rising.

An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 shows a cooking device in which a heating device 1 such as a microwave oven is installed on the floor of a kitchen, and a table 3 having a plurality of stoves 2 is mounted above the heating device 1. An intake section 5 is installed at the rear of the table 3 for discharging steam, exhaust gas, etc. generated when an object 4 to be heated is heated by the stove 2, and communicates with an exhaust fan 7 via an exhaust duct 6. A storage box 9 for storing an air guide 8 for directing steam and exhaust gas generated during cooking in one direction is installed at the rear of the intake port 5, and the air guide 8 moves up and down by a motor 10 so that it can be moved in and out. That is, when the ventilation fan 7 operates, the motor 8 rotates as shown in FIG. 3, the arm 12 fixed to the motor shaft 11 rises, the air guide support fitting 13 rises to lift the air guide 8, and the upper limit switch 14 is operated. Then, the motor 10 is stopped and the lifting operation is stopped.

The air guide 8 is made of a thin stainless steel material with a thickness of approximately 0.4 to 0.8 mm, and has a weight 1 at both ends thereof having a notch 15 at an angle θ as shown in FIG.
6 is attached, as the air guide 8 rises, it bends forward and comes to rest as shown by the dashed line in the final figure.

Therefore, air moves as shown by arrow A, and steam, exhaust gas, etc. generated from the stove 2 are sucked in from the intake section 5 and are forcibly discharged outdoors through the exhaust duct 6. At this time, the cooling airflow B of the table 3 and the exhaust air C of the heating device 1 are also forcedly discharged outdoors.

Next, when the ventilation fan 7 stops, the motor 10 rotates in the opposite direction, the arm 12 and the air guide support fitting 13 descend, and the lower limit switch 17 is operated, the motor 10 is stopped, and the air guide 8 is stored in the storage box 9. Ru.

In the above configuration, the following effects occur.

(1) Provide an exhaust air intake part 5 at the rear of the table 3,
Furthermore, by attaching an air guide 8 that can freely go in and out at the rear, the air guide 8 is raised only when necessary, and steam, exhaust gas, etc. generated during heating are introduced into the intake port as a laminar flow, so that multiple stoves 2 can be used. Even in the case where there are a number of gases, the air guide 8 covers the entire surface of the stove 2 and forcibly sucks it in, so that the collection rate is high and most of the steam, exhaust gas, etc. are discharged from the intake section 5 by the exhaust fan 7. Therefore, the air in the kitchen is not polluted and a clean environment can be maintained.

(2) When cooking tempura and other foods, oil, oily smoke, etc. may scatter and cause damage to the cabinet 19 on the rear wall and ceiling.
However, the air guide 8 of this device can prevent these stains. In particular, it was very troublesome to clean the window 20 on the rear wall surface after every cooking, but since the air guide 8 prevents it from getting dirty, a large window can be installed. Therefore, it is possible to have a bright kitchen that has a good view of the outside from the kitchen and can take in sufficient sunlight.

(3) Since there is no need for a ventilation hood above the stove 2, a cabinet 19 or a hanging cabinet can be freely installed on the wall in that area.

(4) Since the air guide 8 is moved in and out by the driving force of the motor 10, the user can operate it with a single switch, and since it is linked with the exhaust fan 7, steam and exhaust gas can be reliably introduced into the intake section 5. Can be discharged outdoors.

(5) The air guide 8 is simply received by the upper receiving part 18 of the air guide support fitting 13 and can be easily removed and cleaned. In particular, since dirt is concentrated on the air guide 8, cleaning of the air guide 8 is the main task, and cleaning of other parts becomes easy.

(6) The air guide 8 is made of a thin metal plate, and weights 16 with cutouts 15 are attached to both ends of the air guide 8 so that it can be bent forward, making it possible to implement it with a very simple device and making it economical. It is durable, has excellent heat resistance, and is easy to clean because it is a flat plate.

In the above embodiment, an oil receiver (not shown) may be provided at the lower end of the air guide 8 to prevent oil attached to the lower part of the air guide 8 from falling onto the bottom surface of the storage portion, making cleaning even easier. Become.

As described above, according to the present invention, a movable air guide is provided on the rear side of the cooking device, and steam, exhaust gas, etc. from the stove are discharged outdoors by an exhaust fan provided on the rear side of the cooking device. This can prevent stains around the cooking device. Furthermore, since the exhaust hood that conventionally occupies the area above the stove becomes unnecessary, the space can be used for other hanging cabinets, etc., and the kitchen can be used effectively. In addition, cleaning after cooking, which was done in the past, is now mainly done through air guides, which makes cleaning much easier and has many other effects. By automatically extruding and automatically storing the air guide in conjunction with the exhaust fan, the air guide, which is the most likely to get dirty, is stored when the exhaust fan is not in use, so the beauty of the kitchen, etc. can be maintained.
