Abstract

PURPOSE:To prevent the circumference of a kitchen range from contamination by communicating a suction port provided at the rear part of the kitchen range and a heating chamber with an air exhaust duct with a fan, and providing an air guide which freely enters or leaves the suction port, in the range with a gas heater and the like. CONSTITUTION:A fan 7 is operated with the starting of cooking, and in linkage therewith, an air guide 8 operates a limit siwtch and ascends from an accommodating part 9 until the limit switch stops to cover the upper space of the kitchen range 2. As a result, the exhaust gas A of the kitchen range 2 is pulled by the air guide 8 and flows from the suction port 9 to the exhaust duct 6. An exhaust air C of the heating chamber 1 and a cooling air current B of a table 3 are sucked up into the exhaust air duct 6. With the stop of the fan 7, the air guide 8 is accommodated in the accommodating part 9 by the reverse rotation of a motor (not shown). By this construction, contaminations at the kitchen range are prevented and the space at the upper part of the kitchen range can be utilized effectively.

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 devices of this type include a. A ventilation fan and a hood are installed on the rear wall above the stove, and an exhaust inlet is installed near the stove, and the exhaust is installed on the rear wall through an exhaust duct. The most common method was to release it outdoors using a ventilation fan. However, the above-mentioned method a has drawbacks such as the noise of the ventilation fan easily entering the kitchen and the rear wall surface being easily soiled. ! The above method has the disadvantage that it does 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, and pollutes the air in the kitchen. was there.

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 exhaust gas, etc., all at once, regardless of which 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 part d is installed at the rear of this chi-pull 3 to exhaust steam, exhaust gas, etc. generated at 1 hour when the object 4 to be heated is heated by the stove 2, and the exhaust duct 2.6 is connected to the □),. L
-C, 4° A storage box 9 is installed at the rear of the silent 6 to store an air guide 8 that directs steam and exhaust gas generated during cooking in one direction.When the air guide 8 is operated vertically by the motor 1o, In FIG. 3, the motor 8 rotates, the arm 12 fixed to the motor shaft 11 rises, and the air guide support 13
rises to lift the air guide 8, and operates the upper limit switch 14 to stop the motor 1o and stop the rising operation.

The air guide 8 is made of a thin stainless steel material with a thickness of about 0.4 to 0.81111 mm, and weights 16 having cutouts 16 at an angle θ are attached to both ends of the air guide 8, as shown in FIG. As the air guide 8 rises, it bends forward and finally comes to rest as shown by the dashed line in FIG.

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. Due to the cooling air flow B of the peeling table 3 and the exhaust of the heating device 1, the 'C is also forced to the outside and 6゜'''□;... Next, when the ventilation fan 7 stops, the motor 10 rotates in the opposite direction.
Arm 12. The air guide support fitting 13 is lowered, the lower limit switch 17 is operated, the motor 10 is stopped, and the air guide 8 is stored in the storage box 9.

In the above configuration, the following effects occur.

(1) An exhaust intake part 6 is provided 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. Stove 2 even if there are
Since the air guide 8 covers the entire surface and forcibly sucks in the air, the collection rate is high and most of the steam, exhaust gas, etc. are discharged from the intake section 6 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, oil smoke, etc. are scattered and stain the cabinet 19 on the rear wall and ceiling, but 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 create a bright kitchen that has a good access from the kitchen to the outside and can take in sufficient sunlight.

(3) Since a ventilation hood is not required above the stove 2, a cabinet 19 or a hanging cupboard can be freely installed on the wall surface of that area.

+41 The air guide 8 is moved in and out by the driving force of the motor 1o, so the user can operate it with a single switch, and it also works in conjunction with the exhaust fan 7, so it reliably introduces steam and exhaust gas into the intake section 6 to the outdoors. Can be discharged.

16) 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 accumulates on the air guide 8, cleaning of the air guide 8 is the main task, and cleaning of other parts becomes easy.

16) The air guide 8 is made of a thin metal plate, and weights 16 with notches 16 are attached to both ends of the air guide 8 so that it can be bent forward, so it can be implemented with extremely simple equipment and is economical. It also has excellent heat resistance and is easy to clean because it is a flat plate.

In the above embodiment, the oil adhering to the lower part of the air guide 8 is prevented from falling onto the bottom surface of the storage section.

A configuration in which an oil receiver (not shown) is provided at the lower end of the air guide 8 also facilitates cleaning.

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. In addition, since the exhaust hood that conventionally occupied the area above the stove becomes unnecessary, the smooth surface can be used for other hanging cabinets, etc., making it more effective in the kitchen! It has many effects, such as being able to use it for cooking, and cleaning after cooking, which was done in the conventional way, using the air guide as the main focus, making it much easier.
