Has an L-shaped bayonet-type engagement groove 21 and is detachably engaged with the projection 22 of the case body 11. The front surface of the smoke removing filter 18 serves as a suction port 34.

A smoke sensor 23 is mounted on the outer surface of the case main body 11, and outputs an electric detection signal in response to oil smoke generated by cooking. The output reaches a certain level or more by a control device. When it is determined that
The motor 15 is automatically driven, and when the voltage falls below a certain level, the driving is automatically stopped.

In the above-mentioned control, by using a sensor which outputs various levels of electric signals in response to the amount of oil smoke as the smoke sensor 23, the motor 15 is automatically driven, and when the output level rises, The rotation speed of the motor 15 may be controlled to increase accordingly, and the motor 15 may be automatically stopped when the rotation speed falls below a certain level. In addition, a manual changeover switch is provided to turn off,
"Weak" is displayed, and the motor 1
5 may be controlled manually.

Instead of the smoke sensor 23, a microphone for collecting sound having directivity with respect to sound from below (cooker 26) can be used. The smoke sensor 23 and the microphone detect oil smoke, which is a phenomenon that occurs with cooking, and the sound of meat or the like burning.

The smoke remover 4 and the support arm 3 are detachably connected to each other via a connection pipe 24 provided to the auxiliary case 12 so as to protrude horizontally. A control box 20 for controlling the motor 15 is attached to the support arm 3, and a power-on switch (not shown) of the smoke remover 4 is attached to the control box 20.

An outlet 25 is provided at an appropriate position on the mounting table 1, and the outlet 25 is connected to the power cord 6.

The orientation of the support arm 3 is appropriately determined around the vertical portion (see arrow A in FIG. 1), and the horizontal position of the smoke eliminator 4 is also appropriately adjusted (see arrow B in FIG. 1). The smoke remover 4 is installed downward substantially above the center of the cooker 26.
The direction of the smoke remover 4 may be changed by rotating the smoke remover 4 around the connection pipe 24 as needed, for example, when cleaning or replacing the filter (see arrow C in FIG. 1).

When, for example, a grilled meat dish is cooked on the cooking plate of the cooker 26 and oil smoke is generated, the smoke sensor 23 responds to this and when its output becomes higher than a certain level (or the size of the output becomes larger). The motor 15 is driven and the smoke is removed by the smoke removing filter 18 by the suction action of the fan 16, and the purified air is removed from the exhaust port 1.
It is discharged from 4. The same applies when a microphone for sound collection is used instead of the smoke sensor 23.

Next, in the second embodiment shown in FIGS. 6 and 7, the support pipes 2 and 2 are fixed at diagonal corners of the mounting table 1, respectively, and
The support arms 3, 3 are detachably inserted, and the horizontal portions of the support arms 3, 3 are inserted into connection pipes 24, 24 provided at symmetric positions of the smoke remover 4, and the smoke remover 4 is placed on the mounting table. It is supported in a double-supporting manner above the central portion of the device 1.

In this case, the support pipe 2 and the support arm 3
The relationship of the plug receiver 7 is the same as that of FIG. The same applies to the smoke sensor 23 and a microphone for sound collection that substitutes for the smoke sensor 23.

Further, as shown in FIG.
Instead of a microphone or a microphone, a detecting means in which a light-emitting body 28 such as an LED is attached to a vertical portion of one support arm 3 and an optical sensor 29 is attached to a vertical portion of the other support arm 3 opposed thereto is adopted. it can. When the light from the light emitter 28 is blocked by oil smoke generated by cooking, the amount of light received by the optical sensor 29 decreases, and the generation of oil smoke is detected. However, the motor is driven after an appropriate delay time to avoid an immediate response to a momentary interruption by a human hand or the like.

Also in this embodiment, similarly to the above-described case, the motor is driven when the amount of received light falls below a certain level, and is stopped when the amount of light exceeds a certain level. Control for changing the rotation speed of the motor can be performed. The strength may be switched by a manual changeover switch.

The other constructions and operations are the same as those of the first embodiment. Therefore, the same parts are denoted by the same reference numerals, and their description is omitted.

The other constructions and operations are the same as those of the first embodiment, so that the same parts are denoted by the same reference numerals and the description thereof is omitted.

As in the third embodiment, the support arm 3 is directly inserted into the guard 31 of the cooker 26 and attached to the guard 31, and two diagonal positions are provided at the diagonal positions as in the second embodiment. It is also possible to insert the support arms 3, 3 to support the smoke remover 4 in a double-supported manner.

[0033]

As described above, according to the present invention, whether the apparatus has a mounting table or the type in which the support arm is directly inserted into the cooker, the apparatus is different from the cooker. Since it can be separated from one cooker and used in another cooker, there is versatility in use,
It can be removed if not needed. In the case of the type using the mounting table, the smoke can be removed simply by mounting the cooking apparatus on the mounting table without causing any change.

In each of the above types, a smoke remover can be installed above the cooker to absorb oily smoke, and the position and direction of the smoke remover can be changed as necessary.
Efficient smoke removal can be performed.

Further, since the smoke removing device is not provided by using the cooking plate of the cooker, there is an advantage that the effective use range of the cooking surface is not affected.
