TECHNICAL FIELD The present invention relates to a ventilation device.

[0002]

2. Description of the Related Art Generally, in a kitchen, a ventilation device such as a ventilation fan is installed above a cooking device such as a gas cooker such as a gas stove or a gas stove, or an electric cooker such as an electric stove or a microwave oven. During the cooking operation of this type of cooking utensil, it is necessary to discharge oil smoke and water vapor and to ventilate the room, so that the ventilation fan is operated. In particular, in recent years when highly airtight houses are becoming common, indoor ventilation at the time of combustion is indispensable when the cooking appliance is a gas appliance.

However, the operation for operating the cooking appliance (for example, ignition and heat power adjustment in the case of gas appliance) and the operation for performing the ventilation operation of the ventilation device are separately performed, and the cooking operation of the cooking appliance is performed. At that time, a number of troublesome operations are required. In particular, in the range hood fan, which is a ventilation device for system kitchens that has recently been seen, the ventilation operation switch is often installed in front of the hood located at a relatively high place, and it is a switch for the elderly and short people. It is difficult to operate. In addition, even if the cookware is operated during cooking, it is possible to forget the switch operation of the ventilation device and perform cooking without ventilation.

Therefore, there is known an interlocking system in which the ventilation device is operated in association with the operation of the cooking utensil. In this type of interlocking system, for example, the gas cooker and the ventilator are connected by a signal line, the gas cooker is provided with a detection means for detecting its combustion operation, and the detection means sends the signal through the signal line. Operate the ventilator according to the signal provided. By doing so, the ventilation device is automatically operated by performing the combustion operation of the gas cooker, and it is possible to prevent a plurality of operation operations and forgetting ventilation as described above.

[0005]

However, since the cooking utensil and the ventilation device are connected by the signal line, there is a disadvantage that the wiring work is required. If the interlocking system is used between the cooking utensil and the ventilation device that have already been used (so-called retrofitting), is it necessary to purchase a new cooking utensil with the built-in detection means? Or, there is an inconvenience that the work of attaching the detection means to an existing cooking utensil must be performed.

In order to eliminate such inconvenience, the present invention aims to provide a ventilation device which can perform ventilation operation in conjunction with the operation of cooking utensils, does not require wiring work, and can be easily installed afterwards. And

[0007]

In order to achieve the above object, the present invention provides a main body having ventilation means provided above the cooking utensil, a sensor for sensing the operation of the cooking utensil, and the main body.

The detection signal of the sensor is sent to the ventilation operation control means provided in the ventilation device main body, and the ventilation operation of the ventilation means is performed by the ventilation operation control means.

As described above, according to the present invention, since the ventilation operation can be performed according to the operation of the cooking utensil without connecting the cooking utensil and the ventilation device by the signal line, the wiring work can be omitted. Moreover, it is not necessary to provide the cooking utensil with the means for detecting the operation as in the prior art, and the existing cooking utensil can be used as it is, so that the retrofitting can be extremely easily performed.

Further, in the present invention, when the cooker is a gas cooker, a sensor that can be used is, for example, a temperature sensor that detects heat generated during combustion, a gas sensor that detects combustion exhaust gas, and an infrared ray emitted from a flame. Examples thereof include an infrared sensor and an ultraviolet sensor that senses ultraviolet rays emitted from sparks and flames at the time of ignition due to discharge. Further, as a sensor that can be used in the present invention when the cooking utensil is an electric cooker, for example, a temperature sensor that senses heat of a heat generating portion (heater or the like) as a heating source of the electric cooker can be mentioned. And no matter which sensor is used,

DETAILED DESCRIPTION OF THE INVENTION An embodiment of the present invention will be described with reference to the drawings. FIG. 1 is an explanatory front view showing an installation example of the ventilation device of the present embodiment, FIG. 2 is an explanatory side view of FIG. 1, FIG. 3 is a block diagram showing a schematic configuration of the ventilation device of the present embodiment, and FIG. 5A and 5B are explanatory views showing the moving device.
6A and 6B are explanatory views showing the margin holding device, FIG.
FIG. 9 is an explanatory diagram showing another embodiment.

In FIG. 1 and FIG. 2, 1 is a gas stove (gas cooker) which is a cooking appliance, and 2 is a range hood fan (ventilator) provided above the gas stove 1.

As shown in FIG. 1, the gas stove 1 is
In a so-called system kitchen, the counter 3 is embedded and fixed (built-in), and a top plate 4 exposed on the counter 3 is provided with a plurality of stove burners (stove sections) 5. Further, the gas stove 1 has a built-in grill 6, and as shown in FIG. 2, an exhaust port 7 of the grill 6 is opened at the rear edge of the top plate 4. Further, as shown in FIG. 1, the gas stove 1 is provided with operation knobs 8 on the front surface thereof for adjusting ignition and heat power of the stove burner 5 and the grill 6.

As shown in FIGS. 1 and 2, the range hood fan 2 has a ventilation plate 9 having a top plate 4 of the gas stove 1.
The hood portion 10 (main body) installed so as to project toward the front so as to face the fan unit, and a fan device 11 which is a ventilation means provided through the rear wall of the hood portion 10 (not shown).
(See FIG. 3).

A peripheral edge portion 17 of the ventilation port 9 of the hood portion 10
Is provided with a rod-shaped support member 12 extending to the vicinity of the top plate 4 of the gas stove 1 (a position immediately above the exhaust port 7 of the grill 6 in the figure), and a sensor 13 is provided at the tip of the support member 12. It is supported.

The sensor 13 is for detecting the combustion operation of each stove burner 5 and the grill 6 of the gas stove 1. In the present embodiment, the heat of the flame of each stove burner 5 and the exhaust port of the grill 6 are detected. A temperature sensor that senses exhaust heat emitted from No. 7 was adopted. In the present invention, the sensor 13 is not limited to the temperature sensor, and examples thereof include a gas sensor for detecting combustion exhaust gas, an infrared sensor for detecting infrared rays emitted from a flame, and an ultraviolet ray emitted from sparks or flames caused by discharge during ignition. It is possible to employ an ultraviolet sensor or the like for detecting the above, and further, such plural kinds of sensors may be integrally supported at the tip of the support member 12.

The sensor 13 is connected to the ventilation operation control means 15 via a signal line 14 as shown in FIG. The ventilation operation control means 15 is built in the hood portion 10 or the fan device 11 of the range hood fan 2, and operates the fan device 11 in response to a signal when the sensor 13 detects combustion.

As shown in FIGS. 1 and 2, the support member 12 is formed so as to be expandable and contractable by slidably inserting and connecting a plurality of cylindrical members having different diameters. A signal line 14 (see FIG. 3) from the sensor 13 supported at the tip is built in and extends downward. Moreover, since the support member 12 has a structure in which a plurality of cylindrical members are inserted and connected, the support member 12 can be rotated around the axis at any connection portion, and if the sensor 13 supported at the tip of the support member 12 has directivity. Even if there is, the direction of the sensor 13 can be rotated by this.

The support member 12, as shown in FIG.
The moving device 2 is attached to the peripheral portion 17 of the ventilation port 9 of the hood portion 10.
They are connected via 1 . Signal lines 14 by the sensor 13 ahead end is attached is connected to the ventilation operation control means 15 is inserted through the inner portion of the support member 12.

[0026]

[0027] The mobile device 21 includes, as shown in FIG. 4,
A pair of rollers 23, 23 rotatably attached to the base end portion 12a of the support member 12 by a shaft 22, and a peripheral edge portion 17
And a slit 24 formed in the. The slit 24
Is formed to have a predetermined length in the lateral direction of the gas stove 1 shown in FIG . This length is the moving distance of the support member 12 in the horizontal direction.

The moving device 21 moves the supporting member 12 horizontally above the gas stove 1 (horizontal direction as shown by the phantom line in FIG. 1), whereby the sensor supported at the tip of the supporting member 12 is moved. 13 can be placed in a suitable position above the gas stove 1.

Further, the support member 1 by the moving device 21
In order to maintain the electrical connection between the sensor 13 and the ventilation operation control means 15 even if the moving member 2 is moved or the support member 12 is expanded or contracted, the signal line 14 is provided with one of them as shown in FIG. It is provided with a margin portion 14a which is long and has a margin.

The margin portion 14a, as shown in FIG.
By providing the allowance holding device 25, the device can be held so that it can be pulled out without being entangled. That is, the margin holding device 25 has an arm 27 that is swingable by having one end pivotally attached to the inner wall of the hood portion 10 on the shaft 26, and a shaft 28 at the other end of the arm 27. Is rotatably supported by the tension pulley 2 with the allowance 14a.
9, a spring 30 for urging the arm 27 in the direction of the arrow, and a pair of guide pulleys 31, 31 for guiding the allowance portion 14a toward the tension pulley 29 at a fixed position. As a result, when the signal line 14 is pulled by the expansion and contraction or movement of the support member 12, the arm 27 swings through the tension pulley 29 in a direction opposite to the bias of the spring 30, and is constantly moved to the allowance portion 14a. The signal line 14 can be sent out in a state where tension is applied, and when there is a surplus in the signal line 14, the arm 27 swings in the urging direction of the spring 30 to constantly apply tension to the allowance portion 14a. The signal line 14 can be pulled in by.

[0031]

[0032] Incidentally, the biasing force of the spring 30 of the margin portion holding device 25, or to contract the support member 12 of the tension through the signal line 14, the support from the moving position by the moving equipment 2 1 member 12 Is not enough to move
It goes without saying that the margin 14a is simply set to prevent entanglement.

The operation of the range hood fan 2 having the above structure will be described. First, as shown in FIGS. 1 and 2, the support member 12 is extended toward the gas stove 1, and the sensor 13 is placed near the gas stove 1. Keep it in place. At this time, all the stove burners 5 are moved by the vertical expansion and contraction of the support member 12, the lateral movement, and the rotation around the axis.
Also, the sensor 13 can be placed at an optimum position where the heat from the exhaust port 7 of the grill 6 can be sensed.

When the stove burner 5 or the grill 6 of the gas stove 1 starts burning, its heat is detected by the sensor 13, and the detection signal is sent to the ventilation operation control means 15 via the signal line 14. The ventilation operation control means 15 responds to the detection signal sent from the sensor 13 by the fan device 1
Operate 1 and ventilate. After that, when the use of the gas stove 1 is stopped, the sensing signal from the sensor 13 is stopped,
The ventilation operation control means 15 stops the operation of the fan device 11. As described above, according to the present embodiment, large-scale wiring work for electrically connecting the gas stove 1 and the range hood fan 2 with the signal line is unnecessary. Moreover, since the gas stove 1 itself does not need a means for detecting combustion in order to interlock ventilation operation, there is no need to purchase a dedicated gas stove, and it is most suitable for sensing the combustion with the existing gas stove 1 as it is. Since the sensor 13 can be positioned at a suitable position, retrofitting is extremely easy.

In the present embodiment, the support member 12 is allowed to expand and contract, but if the most suitable position for sensing the combustion of the gas stove 1 is clear, the rod-shaped support member does not expand or contract to that position. (Not shown) may be extended and the sensor 13 may be supported at its tip.

Further, without providing the support member 12, for example, as shown in FIG. 6, the sensor 13 is fixed to the rear wall 16 near the gas stove 1 at a position where combustion of the gas stove 1 can be detected. The sensor 13 and the ventilation operation control means 15 may be simply wired. Also in this case, it is preferable to employ the above-mentioned allowance holding device 25 .

Further, for example, as shown in phantom in FIG. 6, the sensor 13 may be detachably attached to the peripheral portion 17 of the hood portion 10 or the like. That is, when the combustion of the gas stove 1 can be detected with the sensor 13 attached to the hood portion 10, the gas stove 1 and the fan device 11 can be interlocked in that state. Also, if combustion is not sensed sufficiently,
The sensor 13 is detached from the hood portion 10 and the sensor 1
3, the ventilation operation control means 15 and the electrical connection by the signal line 14 are maintained, the support member 12 is provided, or the sensor 13 is installed on the rear wall 16 in the vicinity of the gas stove 1 to install the gas stove 1. The sensor 13 can be located at a position where combustion can be well sensed. Also in this case, it is needless to say that it is preferable to adopt the above-mentioned margin holding device 25 .

In the present embodiment, the system kitchen shown in FIG. 1 has been described as an example. However, even if the gas stove 1 is a so-called table stove (not shown) not fixed to the counter 3, the present invention can be used. The interlocking system of can be adopted.

Further, in the above-mentioned embodiment, the gas stove 1 having the grill 6 built therein as the cooking utensil has been described as an example, but the present invention is also applicable to a gas stove having an oven under the gas stove 1. Furthermore, in the above-described embodiment, an example of the gas stove 1 (gas cooker) using gas combustion as a heat source has been described, but the heat source may be an electric heating element such as a heater, and for example, electric cooking such as an electric stove or an electric oven. It may be a container.
