Description

  The present invention relates to a circulation type cooking ventilator capable of appropriately purifying exhaust gases such as oil smoke, water vapor, and odor that are generated when cooking using an induction heating cooker.

It is common practice to collect exhaust fumes, water vapor, odors, and the like emitted from a heating cooker provided on a cooking table with a ventilation hood provided above the cooking table, and to discharge it outdoors with a ventilation fan. In this conventional apparatus, exhaust air is discharged outdoors, so that the outside air is contaminated, which is not preferable. Therefore, as disclosed in Japanese Patent Laid-Open No. 9-196423, it has been proposed to provide an air clean range hood above the cooking table to clean the exhaust and circulate it indoors.
JP-A-9-196423

  However, since the above-mentioned air cleaning range hood is expensive and is attached to the ceiling above the cooking table, it is doubtful whether all the exhaust can be taken in and cleaned, and the indoor air will become dirty over time. Therefore, the present invention uses an induction overheating cooker as a heating cooker, hardly fouls indoor air, and does not involve construction such as tearing a part of the wall of the room and providing a duct outside. An object is to provide an apparatus.

  The cooking ventilator according to the present invention includes a duct in which an intake port is disposed at the upper portion of the induction superheater, a purifier body that purifies exhaust gas guided by the duct, and exhaust gas purified by the purifier body. And a ventilator for guiding the air in the direction of the air inlet, wherein the purifier main body is provided with a purifying chamber in which the exhaust gas is introduced into an aqueous solution in the form of small bubbles and the aqueous solution is stirred.

Further, the exhaust gas for making the exhaust gas into a small bubble shape is constituted by a bubble generating plate having a large number of small holes.
Further, the present invention is characterized in that a filter plate is provided that removes odor from the exhaust gas that has been bubbled through the aqueous solution.
Further, the purifier body is provided with an exhaust intake chamber and an aqueous solution reservoir chamber, the purifier chamber and the exhaust intake chamber are disposed adjacent to each other above the aqueous solution reservoir chamber, and a lower end of a partition plate between the purifier chamber and the exhaust intake chamber The portion is extended to the aqueous solution storage chamber.

Further, an ultrasonic generator for generating mist in the exhaust intake chamber is provided in the aqueous solution reservoir chamber.
Furthermore, a drain port for discharging the aqueous solution is provided in the purification chamber, and a supply port for supplying the aqueous solution to the aqueous solution reservoir chamber is provided.

  According to the present invention, the exhaust gas generated when cooking using the induction heating cooker passes through the duct and is purified by the purifier main body, and then comes out of the ventilator again to the outside of the duct. It is configured. In other words, since the device is a single unit, it can be installed as long as there is a certain space, and it is not necessary to break out the wall of the room and put out a duct outside, so it is easily installed in the home kitchen be able to.

  The purifier main body is configured so that the exhaust gas is made into small bubbles and guided to the aqueous solution to bring the aqueous solution into a stirring state. Therefore, the oil content and moisture of the exhaust gas can be separated and removed from the exhaust gas. In addition, the bubble generating plate provided with a large number of small holes guides the exhaust gas to the aqueous solution by forming small bubbles. However, since the hole of the bubble generating plate is a small hole, the aqueous solution does not leak downward from the bubble generating plate.

Also, odor can be generated by the filter plate. Furthermore, mist is generated by an ultrasonic generator to facilitate separation of oil and moisture from the exhaust before purification, and purification in the subsequent purification chamber is facilitated.
Further, since the aqueous solution in the purification chamber can be discharged and the aqueous solution can be supplied to the aqueous solution storage chamber, it can be used continuously as appropriate.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a principle diagram of a cooking apparatus according to an embodiment of the present invention, and FIGS. 2, 3 and 4 are drawings of an apparatus implementing the apparatus. As shown in FIGS. 1, 2, 3, and 4, a fishing cabinet 3 is provided at the corner of the wall 1 and ceiling 2 of the room, and an induction overheating cooker 4 is installed below the fishing cabinet 3, and this induction overheating is performed. A purification ventilation device 7 is accommodated between the cooking device 4 and a table 6 provided on the floor 5.

The purification ventilator 7 is provided with a duct 10 that sucks in exhaust 9 such as water vapor, odor, and oil smoke coming out of the pan 8 used in the induction overheating cooker 4, and 10a is an inlet. The suction port 10 a is disposed near the lower end of the fishing cabinet 3. The duct 10 is led to the purification ventilation main body 11 through the space between the wall surface 1 and the induction overheating cooker 10.
The purification ventilation main body 11 is composed of three communicating chambers. The first chamber is an exhaust intake chamber 12 connected to the outlet 10 b of the duct 10, the second chamber is an aqueous solution reservoir chamber 13 such as water communicating with the exhaust intake 12, and the third chamber is an aqueous solution reservoir chamber 13. This is a purification chamber 14 that communicates with the purification chamber 14.

An ultrasonic generator 15 for generating an ultrasonic wave having a frequency of about 2, 4 MHZ is accommodated in the aqueous solution storage chamber 13, and the aqueous solution 16 is vibrated by the ultrasonic generator 15, and the mist 17 enters the exhaust intake chamber 12. Is generated. The aqueous solution 16 may be tap water, but other components may be added.
The purification chamber 14 is provided with a bubble generation plate 14a on the lower side, and a filter plate 14b is arranged on the upper portion thereof at a predetermined interval. As the bubble generation plate 14a, for example, a stainless steel or aluminum plate of 60 to 80 mesh is used. The aperture ratio is preferably about 50% or less and about 30%. What is necessary is just to provide many small holes. The small holes include those configured in a mesh shape having a small gap. The filter plate 14b uses, for example, a honeycomb filter made of activated carbon, and is used for deodorization.

A ventilation device 18 such as a sirocco fan is provided on the upper portion of the filter plate 14b. The outlet of the ventilation device 18 is connected to a duct 19, and the outlet 20 of the duct 19 is provided beside the induction heating cooker 4. You may make it provide another exit facing the exit 2 with the induction heating cooking appliance 4 inside. Instead of the exit 2, only another exit may be used.
Although not shown in FIGS. 2, 3, and 4, as shown in FIG. 1, a water supply port 21 for supplying an aqueous solution to the aqueous solution reservoir chamber 13 faces the aqueous solution reservoir chamber 13, and a drain outlet for discharging waste liquid. 22 exits the purification chamber 14. Solenoid valves 23 and 24 are provided at the water supply port 21 and the drain port 22, respectively.

  The purification chamber 14 and the exhaust intake chamber 12 are provided next to each other on the aqueous solution storage chamber 13, and the partition plate 25 between the purification chamber 14 and the exhaust intake chamber 12 extends into the aqueous solution storage chamber 13. The two chambers 12 and 14 do not need to be exactly adjacent to each other with a single partition plate, and may be arranged at a constant interval. In this case, the number of partition plates is two, but the number of partition plates 25 may be one or two.

  When the power switch of the fusion heating cooker 4 is turned on, the ventilation device 17 is electrically configured to operate in conjunction with this. Further, when the power switch is turned off, the electromagnetic valves 23 and 24 are operated so that the aqueous solution is supplied from the water supply port 21 to the aqueous solution reservoir chamber 13 and when the water level reaches a predetermined level, the electromagnetic valve 23 is operated to stop the water supply. It is configured. Further, the waste liquid is discharged from the drain port 22, and when all of the waste liquid is discharged, the electromagnetic valve 24 operates to close the valve.

The operations of the electromagnetic valves 23 and 24 may be manually performed as appropriate. That is, when the induction heating cooker 4 is turned on and off in a short time, it is inefficient to supply drainage water each time.
Next, the operation of this apparatus will be described with reference to FIG.
First, the aqueous solution 16 is put in the aqueous solution reservoir 13 up to level A. This level A is a level at which the lower end of the partition plate 25 sufficiently enters the aqueous solution 16. The waste liquid in the purification chamber 14 is removed from the drain port 22. With the water supply port 21 and the drain port 22 closed, the power switch of the induction heating cooker 4 is turned on. Then, the ventilation device 17 starts operation, and the exhaust of the purification ventilation chamber 7 is pulled in the direction of the arrow. At the same time, the ultrasonic generator 15 operates to generate a mist 17 in the exhaust intake chamber 12.

  The exhaust 9 generated from the pan 8 enters from the air inlet 10 a of the duct 10 and enters the exhaust intake chamber 12 through the duct 10. The exhaust 9 comes into contact with the mist 17 so that the oil and water are easily separated. Also, some odor is lost. The aqueous solution in the aqueous solution reservoir 13 is sucked and enters the purification chamber 14. When the water surface of the aqueous solution 16 is initially at A, the aqueous solution enters the purification chamber 14, but when the water surface falls below the partition plate 25, for example, when the water surface becomes B, the exhaust 9 passes through between the lower end of the partition plate 25 and the water surface and is purified. Head towards room 14.

  The exhaust gas 9 enters the purification chamber 14 through a small hole in the bubble generation plate 14a. Then, the exhaust 9 becomes a small bubble, and the water in the purification chamber 14 is brought into a stirring state. As a result, the oil and moisture in the exhaust gas are separated, and the oil is accumulated above the purification chamber 14. The exhaust gas from which the oil and moisture have been removed passes through the filter plate 14b, and the odor is removed by activated carbon. The exhaust gas is purified, passes through the ventilation device 17, passes through the duct 19, exits the outlet 20, and goes to the intake port 10 a.

  When cooking is completed and the power switch of the induction overheating cooker 4 is turned off, the ventilation device 17 and the ultrasonic generator 15 are stopped. At the same time, the electromagnetic valve 22.23 operates to open the valve, and the waste liquid in the purification chamber 14 is removed from the drain port 22. Further, an aqueous solution is supplied to the solution reservoir 13. When the waste liquid is removed, the electromagnetic valve 24 is operated and the valve is closed. When the water surface reaches A, the electromagnetic valve 23 operates and the valve is closed.

It should be noted that the bubble generating plate 14a is perforated, and it is considered that the aqueous solution leaks downward. However, since the hole is a small hole, the waste liquid in the purification chamber 14 passes downward through the bubble generating plate 14a. It does not fall and is all removed from the drain port 22.
Since the cooking ventilator is placed around the water, water supply and drainage can be realized easily. Although it is sufficient to put water into the aqueous solution storage chamber 13, it is also possible to add something like a cleaning agent. The bubble generating plate 14a and the filter plate 14b may be removed and cleaned as appropriate. The filter plate 14b may be replaced.

  As described above, the exhaust gas generated when cooking using the induction heating cooker 4 passes through the duct 10 and is purified by the purifier main body 11 and then comes out again from the ventilator 18 to the outside of the air inlet 10a of the duct 10. Configured to head towards. In other words, since the device is a single unit, it can be installed as long as there is a certain space, and it is not necessary to break out the wall of the room and put out a duct outside, so it is easily installed in the home kitchen be able to.

And the purifier main body 11 made exhaust_gas | exhaustion into a small bubble, was guide | induced to aqueous solution, and was made to stir the aqueous solution, Therefore The oil component and water | moisture content of exhaust_gas | exhaustion can be isolate | separated and removed from exhaust_gas | exhaustion.
In addition, the bubble generating plate 14a provided with a large number of small holes guides the exhaust gas into a small bubble. However, since the hole of the bubble generating plate 14a is a small hole, the aqueous solution leaks downward from the bubble generating plate 14a. There is no.

  Also, odor can be removed by the filter plate 14b. Furthermore, the mist 17 is generated by the ultrasonic generator 15 to facilitate separation of the oil and moisture of the exhaust before purification, and the subsequent purification in the purification chamber 14 becomes easy.

  The present invention is useful for a cooking ventilation device in a kitchen such as a home.
