Description

  The present invention relates to a ventilator for a kitchen (kitchen).

  When cooking in a kitchen, heat from a heating device such as a gas range or IH (Induction Heating, electromagnetic induction heating) cooking heater or cooking is transmitted to the cook, and in the summer, the cook is uncomfortable. In addition, the smell of cooking may flow from the kitchen to the living room, etc., and smell the visitors in the living room. For this reason, ventilators have been developed that cut off as much as possible the heat and smell of cooking, as well as air containing unpleasant and harmful substances such as combustion exhaust gas (hereinafter referred to as “cooking air” as appropriate). .

  For example, a ventilator is known that includes a rotatable child ventilation duct at the tip of an extension duct that extends from the side surface of a range hood (see, for example, Patent Document 1). According to this ventilator, by positioning the child ventilation duct above a pan, a frying pan, or the like, air contaminated with oily smoke or moist air can be discharged outside the room.

  Further, there is known a gas bed periphery in which an air curtain is formed around the gas table (for example, see Patent Document 2). An air supply device and an exhaust device are arranged on the upper side of the exhaust hood around the gas table. The air supply device introduces outside air to the lower side of the gas table, and the introduced outside air is discharged from the gas table to the outdoor by the exhaust device. In this way, an air curtain is formed around the gas table to cut off cooking air.

Furthermore, ventilator sucks like fumes or oil-water mist are known in the cyclone-shaped (e.g., see Patent Document 3.). In this ventilator, a nozzle plate is disposed above a cooking table provided with heating means. A round hole is formed in the nozzle plate so as to face the heating means, and a lower exhaust pipe is connected to the round hole. ing. The lower exhaust pipe is connected to the upper exhaust pipe via a filter box, and the upper exhaust pipe is connected to the exhaust duct with its upper end fixed to the building beam. Further, a nozzle ring formed in a bowl shape whose diameter gradually increases toward the lower end is provided at the lower end of the lower exhaust pipe. Then, a cyclone phenomenon occurs due to the bowl-shaped nozzle ring, and smoke, oil mist, etc. are instantaneously sucked.

  By the way, in the ventilator described in Patent Document 1, by placing the child ventilation duct on a pan or a frying pan, the smell from the pan can be efficiently discharged, but the heat is cut off. I can't. In addition, exhausting air from multiple pans and pans at the same time requires multiple child ventilation ducts, which complicates the configuration, and further, because the area where the child ventilation ducts need to rotate is wide, There is a risk of malfunction.

  Further, around the gas table described in Patent Document 2, a complicated duct mechanism is required to form an air curtain, and much labor and time are required for maintenance and replacement of the air supply device and the exhaust device. . Furthermore, the ventilation device described in Patent Document 3 has a complicated and large-scale mechanism and configuration of the device, and requires special consideration such as fixing the upper exhaust pipe to the building beam. For this reason, it is considered that it is often difficult to arrange in a home cooking place, and lacks versatility. Moreover, in the technique described in patent documents 1-3, since cooking air contacts direct with atmospheric air, mixing of both air, discomfort, and spreading | diffusion of a harmful substance cannot be avoided.

  Accordingly, an object of the present invention is to provide a ventilator for a kitchen that can effectively block cooking air by cooking and has a simple configuration.

In order to achieve the above object, the invention described in claim 1 is characterized in that at least a front surface of a heating device is shielded to move up and down so that the light-transmitting shielding body can be opened and closed, and outside air is transferred to the heating device. surface of the shield by the supply and discharge means for discharging the pre-Symbol heating device upper portion of the air to the outside is supplied, the shield in contact with the surface of the heating device side of the shield is vertically moved toward the A wiping body for wiping off deposits adhering to the heating device, wherein the supply / discharge means is disposed on the back side of the heating device and supplies outside air to the heating device, and the heating device And an exhaust means for discharging the air above the heating device to the outside .

That is, air is circulated on the heating device side with respect to the shielding body. Also, outside air is supplied from the back side of the heating device to the heating device by the outside air intake means, and air above the heating device is discharged from above the heating device to the outside by the exhaust means.

The invention according to claim 2 is the ventilator for a kitchen according to claim 1, wherein the predetermined time has passed with the shielding body closed, and the temperature on the heating device side is predetermined. An alarm means is provided that issues an alarm when at least one of a condition that the temperature is reached and a condition that a predetermined odor is detected on the heating device side is satisfied.

  According to this invention, when the predetermined time has passed with the shielding body closed, the temperature on the heating device side reaches the predetermined temperature, or the predetermined odor is detected on the heating device side. An alarm is issued by the alarm means.

According to the first aspect of the present invention, the cooking air emitted from the heating device side can be effectively blocked by closing the shielding body, giving the cook a discomfort due to heat, and smell. Can be prevented from flowing into the room. In addition, since air is circulated on the heating device side with the shielding body closed, cooking air is less likely to be released indoors, and cooking air can be blocked more effectively. Moreover, since the combustion exhaust gas contained in the cooking air does not leak, the intake amount of outside air is small, and it becomes possible to reduce the power cost by reducing the supply and discharge means such as the exhaust fan. Moreover , since it is only necessary to provide the shielding body and the supply / discharge means, the configuration is simple, and it is possible to apply and arrange it in any of the commercial and domestic kitchens. In addition, it is possible to configure the outside air intake means with existing louvers, etc., and the exhaust means with existing exhaust systems (such as hoods and exhaust fans), and simply install a shield on the existing equipment. A ventilation device can be constructed. Furthermore, deposits such as oil and water adhering to the surface of the shielding body on the side of the heating device are wiped off by the wiping body, preventing the deposits from being scattered and preventing the spread of odor due to the scattering.

According to the second and third aspects of the present invention, the predetermined time elapses with the shielding body closed, the temperature on the heating device side reaches the predetermined temperature, or the predetermined value is set on the heating device side. When the odor is detected, an alarm is issued or heating by the heating device is stopped, so that it is possible to prevent spillage or fire due to overheating.

According to the invention described in claim 4 , since the shielding body is freely deformable, for example, even when a handle of a frying pan protrudes from the heating device side, the heating body can be heated by deforming the shielding body along the handle. The front side of the equipment can be properly shielded.

Also, when the temperature on the heating equipment 101, 102 side reaches a predetermined temperature, the gas supply is cut off and an alarm sound is generated. Furthermore, when a predetermined odor is detected on the heating devices 101 and 102 side, the gas supply is cut off and an alarm sound is generated. Even when the state of the heating devices 101 and 102 cannot be accurately grasped by closing the shielding plate 4 in this way, the gas supply is cut off based on the abnormality in time, temperature and odor. A warning sound is emitted.

  Then, when cooking progresses, the shielding board 4 is opened as mentioned above. At this time, the adhering matter adhering to the shielding plate 4 is wiped off by the roll towel 5 as described above. Next, the cooking state is confirmed. If cooking is completed, the heating devices 101 and 102 are stopped and the pan or the like is taken out. Then, with the shielding plate 4 closed again and the gallery 21 closed, the operation of the exhaust fan 33 is continued. Thereby, the air flows into the heating devices 101 and 102 only from the gap between the front surface 100 b of the cooking table 100 and the shielding plate 4, and the smell, heat, etc. staying above the heating devices 101 and 102 are efficient. Then, it is discharged from the exhaust casing 32 through the range hood 31.

  As mentioned above, according to this ventilation apparatus 1, the cooking air by cooking can be interrupted | blocked effectively by the shielding board 4, and cooking air can be discharged | emitted effectively outside. And since the shielding board 4 is comprised from the fireproof glass board, it becomes possible to interrupt | block cooking air by cooking more effectively. Even when an abnormality occurs in time, temperature, or smell with the shielding plate 4 closed, the safety equipment 6 is provided so that the gas supply is cut off as described above, and an alarm sound is generated. It is possible to prevent spillage or fire caused by overheating.

  Furthermore, deposits such as oil and water adhering to the shielding plate 4 are wiped off by the roll towel 5, so that the deposits can be prevented from scattering and the smell from spreading due to the scattering can be prevented. Moreover, this ventilation apparatus 1 can be constructed only by providing the outside air intake facility 2, the exhaust facility 3, and the shielding plate 4, and the existing cooking place equipped with the outside air intake facility 2 and the exhaust facility 3 has a shielding plate.

(Embodiment 4)
FIG. 9 is a side view (partially cross-sectional view) showing a ventilator 30 for a kitchen according to this embodiment. In this embodiment, the supply / discharge means is mainly composed of a range hood (hood) 7, an air supply duct (outside air intake means) 8, an exhaust duct (exhaust means) 9, and a guide plate 71. Yes.

  The range hood (hood) 7 is disposed above the heating devices 101 and 102 so that the opening 7a faces the range 101. At the upper end of the range hood 7, one end of the air supply duct 8 and the exhaust duct are disposed. 9 is connected to one end. The other end of the air supply duct 8 is arranged facing the outside air (atmosphere), and the external air is introduced into the heating devices 101 and 102 through the air supply duct 8 by the suction action of an exhaust fan 91 described later. It has become. Further, an exhaust fan 91 is disposed on one end side in the exhaust duct 9, and the other end is disposed facing the outside air, and the air above the heating devices 101 and 102 passes through the exhaust duct 9 into the atmosphere ( To the outside).

  The guide plate 71 is disposed in the range hood 7 and guides the outside air supplied from the air supply duct 8 to the front side of the heating devices 101 and 102, and the air on the heating devices 101 and 102 side to the exhaust duct 9 side. It is formed to guide. Specifically, the range hood 7 is formed such that the distance between the range hood 7 and the front plate 7b is wide on the upper side and narrow on the lower side, and the air flow is smooth. That is, the upper side that receives outside air from the air supply duct 8 is wide, and the lower side that receives air from the heating devices 101 and 102 is wide.

  According to the ventilation device 30 provided with such supply and discharge means, in a state in which the shielding glass (a configuration equivalent to the shielding plate in the first embodiment) 4 is closed, as shown in FIG. The supplied outside air is guided to the front side of the heating devices 101 and 102 by the guide plate 71. And the air by the side of the heating equipment 101 and 102 is guide | induced to the exhaust duct 9 side by the guide plate 71, and is discharged | emitted by the exhaust duct 9 outside. In this way, in the state where the shielding glass 4 is closed, air is circulated on the heating devices 101 and 102 side than the shielding glass 4, and cooking air can be more effectively blocked. By doing so, combustion air can be supplied into the range hood 7 while reducing leakage of cooking air to the outside of the range hood 7, and this is transmitted with a small amount of air.

  Furthermore, as shown in FIG. 10, a switching damper 72 can be provided on the upper portion of the front plate 7 b of the range hood 7. In this case, an opening that is closed when the switching damper 72 stands is formed in the range hood 7. In other words, the switching damper 72 allows the indoor space inside the range hood 7 and the outside of the range hood 7 to communicate with each other, or blocks both spaces. The switching damper 72 is rotatably arranged around the lower end portion. When the switching damper 72 is positioned vertically (in the state of the two-dot chain line in the figure), outside air supplied from the air supply duct 8 is removed. Together with the guide plate 71, it is guided to the front side of the heating devices 101 and 102. Further, in a state where the switching damper 72 is tilted sideways (indicated by a broken line in the figure), the flow path of the guide plate 71 is closed, and the outside air supplied from the air supply duct 8 is guided to the indoor side.

  In addition, as shown in FIG. 10, when the switching damper 72 is tilted, the shielding glass 4 is opened a little and the front lower end is opened, the upper air supply side of the range hood 7 and the indoor space such as the kitchen are in communication. In a state where a gap is provided between the shielding glass 4 and the base of the range 101, the following is obtained. That is, the heat on the range 101 side is blocked by the shielding glass 4, and the outside air flowing from the air supply duct 8 to the indoor side forms a tilted deflected air flow toward the range hood 7 side. The air is supplied to the range 101 side through a gap with the base. Further, by turning down the switching damper 72 and operating the air supply fan 81 as the air supply means, the outside air can be guided to the indoor side and the room can be cooled by the outside air. At this time, the air volume (air supply volume) of the air supply fan 81 is slightly larger than the air volume (exhaust volume) of the exhaust fan 91. Thereby, while the taken-in outside air goes to the range hood 7 side, the surplus outside air flows into the indoor side and diffuses while diluting odors and smoke. In addition, it is desirable that such air volume adjustment is performed in the middle of spring or autumn in consideration of the influence on other air conditioning equipment.
