  Induction heaters (also called IH heaters) have become widespread, and kitchens called open types are increasing. In this type of kitchen, kitchen cabinets are arranged in an island type (floating island type) or a peninsula type (peninsula type), and the upper part of the kitchen cabinet is open. In such a kitchen, in the ventilator as shown in Patent Documents 2 and 3, the hood that collects steam and oily smoke is located above the work surface, and there is a feeling of pressure that greatly impairs the feeling of opening. The appearance of is also damaged. In addition, what is shown in Patent Document 1 is capable of sucking steam and oily smoke well when cooking using an induction heater with weak fire control, but when the fire control is strong, When cooking using two or three mouths, there is a problem that sufficient collection performance cannot be obtained if the amount of generated steam or oily smoke is large.

  The present invention has been made in order to solve the above-mentioned problems, and the problem is that the kitchen is excellent in steam and oil smoke collection performance without impairing the feeling of openness and the appearance of the kitchen. It is to obtain a ventilation device for the kitchen, and to provide a kitchen cabinet suitable for an open type kitchen.

  In order to solve the above-mentioned problems, the present invention provides a suction opening that opens forward at the upper front surface of a closed rectangular first duct that constitutes a low-rise barrier having a forwardly inclined front surface. A square-shaped second duct having a blow-out opening that opens downward on both sides of the mouth and having a suction opening that opens into the room is provided side by side with the first duct, and is exhausted to the lower portion of the first duct. The suction side of the blower is connected, and a means for incorporating a blower that forms an air flow from the suction port to the two outlets is employed in the second duct.

  In order to solve the above-mentioned problem, another invention provides a suction opening that opens forward in the upper part of the front face of the closed rectangular first duct that constitutes a low-rise barrier having a front face inclined forward. A rectangular second duct having an air outlet opening downward on both sides of the air inlet and having an air inlet opening in the room is provided alongside the first duct, and exhausted to the outside of the lower part of the first duct. Inductive heating of the first and second ducts of a kitchen ventilator that incorporates a blower that forms an air flow from the inlet to the two outlets in the second duct. The means provided behind the vessel is adopted.

  According to the present invention, there is no hood that collects steam and oily smoke above the work surface, and the steam and oily smoke are smoothly sucked from the suction port provided in the square duct that forms the forward inclined barrier. Can do. Since an induced air flow is blown downward from both sides of the suction port, the vapor and smoke are prevented from diffusing and are smoothly sucked into the suction port. That is, it is possible to obtain a kitchen ventilator having an excellent performance of collecting steam and oily smoke, which does not impair the openness and appearance of the open type kitchen.

  Moreover, according to another invention, the kitchen cabinet with a feeling of opening suitable for an open type kitchen without the food | hood which collects a vapor | steam and oily smoke in the upper part of a work surface is obtained.

  The kitchen ventilator according to the present invention has a square-shaped first barrier that constitutes a low-rise barrier having a front surface that is tilted forward by about 10 to 15 degrees with respect to a vertical plane and has no occlusion (about 350 mm to 450 mm). The main part of the outer shell is constituted by one duct and a square-shaped second duct provided side by side in the center of the back surface of the first duct. The upper end of the first duct is closed, and a suction port that opens forward is provided in the upper front portion. The lower part of the first duct is opened as a connection port, and the suction side of the blower exhausting to the outside is connected in the kitchen cabinet. The second duct is provided with a hammer head portion that holds the upper end of the first duct slightly in an overhang shape at the top, and a blower opening downward on both sides of the suction port of the first duct. There is an exit. The lower side of the upper end of the second duct protruding like a hammer is covered with a curtain plate extending from the front surface of the first duct, and the front surface of the first duct is a flat rectangular flat plate. It has become. The lower end of the second duct is configured as a mounting surface, and is fixed and closed behind the top plate of the kitchen cabinet. A suction port is provided at the lower back of the second duct, and a blower that forms an air flow from the suction port toward the two outlets is incorporated. The flat rectangular flat plate-like front surface of the first duct is a low-rise barrier having substantially the same width as the top plate behind the top plate having, for example, a three-port induction heater.

  According to this kitchen ventilator, there is no hood for collecting steam and oily smoke above the work surface, and only a low standing barrier for collecting steam and oily smoke stands on the work surface of the kitchen cabinet. The openness and appearance of the open kitchen are not impaired. Steam and oily smoke generated from the cooking container on the induction heater rises toward the front surface inclined forward by about 10 to 15 degrees with respect to the vertical surface and is blown downward from both sides of the suction port. Diffusion to the outside is prevented by the air flow induced by the indoor air, and the air is sucked into the first duct from the suction port that opens upward in the upward direction. The reason why diffusion is prevented by the induced air flow is that the periphery of the induced air flow becomes a negative pressure region and attracts the surrounding air. Then, the polluted air sucked into the first duct is exhausted from the floor to the outside through the duct by a blower provided in the kitchen cabinet. Even when two or more induction heaters are used, the two outlets through which the induced air flow is blown are located so as to cover the entire width of the top plate. Without being exhausted.

FIG. 13 is a side view showing another kitchen ventilator, and FIG. 13 is a cross-sectional view showing a kitchen in which another kitchen ventilator is installed.

  The kitchen cabinet 1 of the present embodiment is arranged in an island type or a peninsula type, and is suitable for constituting an open type kitchen that is open upward. On the work surface 2 of the kitchen cabinet 1, as shown in FIG. 2, for example, a top plate 4 provided with a three-way induction heater 3 of strong, medium and weak is provided. In addition to the induction heater 3, a kitchen ventilator is also provided in the kitchen cabinet 1. The kitchen ventilator is a square first that constitutes a low-rise barrier 6 having a front surface 5 inclined forward by about 10 to 15 degrees with respect to a vertical surface and having a low feeling of occlusion (about 350 mm to 450 mm). The main part of the outer shell is constituted by the duct 7 and the square second duct 8 provided in line with the center of the back surface of the first duct 7 (see FIGS. 5 and 6).

The upper end of the first duct 7 is closed, and a suction port (exhaust suction port) 9 that opens forward is provided in the center at the upper end of the front surface as shown in FIG. The suction port 9 is formed in a rectangle close to a square of about 100 square centimeters, and is provided in the center to increase the suction wind speed and increase the collecting power. The lower part of the 1st duct 7 opens as the connection port 10, and the suction side of the air blower 11 which exhausts the outdoors is connected in a kitchen cabinet (refer FIG. 4). The second duct 8 is provided with a hammer head portion 12 that embeds the upper end of the first duct 7 slightly in an overhang shape at the upper portion, and the hammer head portion 12 includes both sides of the suction port 9 of the first duct 7. The air outlet 13 that opens downward is provided (see FIG. 5). From these two outlets 13, as shown in FIG. 8, the attraction | suction airflow A is blown out substantially right below. The lower side of the side portion of the upper end of the second duct 8 that protrudes like a hammer is covered with a curtain plate portion 14 extending from the front surface 5 of the first duct 7, and the front surface 5 of the first duct 7 is A flat, flat plate shape (see FIGS. 2, 3 and 5).

The lower end of the 2nd duct 8 is comprised as the attachment surface 15, is fixed behind the top plate of the kitchen cabinet 1, and is obstruct | occluded. A suction port (blowing suction port) 16 is provided at the lower back of the second duct 8 as shown in FIG. 6, and a blower 17 that forms an air flow from the suction port 16 toward the two blower ports 13 is provided. It is incorporated (see FIG. 4). The flat rectangular flat plate-like front surface 5 of the first duct 7 stands behind the top plate 4 having, for example, a three-port induction heater 3 and has a width substantially the same as that of the top plate 4 that does not cover the top plate 4. It is a low barrier 6. The wind speed of the induced air flow A from the two air outlets 13 is set to be higher than the speed of steam and smoke rising from the cooking vessel placed on the induction heater 3, and the suction air speed to the inlet 9 of the first duct 7. It is set a little slower. More specifically, the blowout air speed from the two air outlets 13 is set to about 3 m / second to about 5 m / second, and the suction air speed to the suction port 9 is set to about 4 m / second to about 10 m / second.

  According to this kitchen ventilator, there is no hood for collecting steam or oily smoke above the work surface 2, and a low standing barrier 6 for collecting steam or oily smoke stands on the work surface 2 of the kitchen cabinet 1. The openness and appearance of the open kitchen are not impaired. Steam and oily smoke generated from the cooking container on the induction heater 3 along with cooking is smoothly following the trajectory to the suction port 9 toward the front surface 5 inclined forward by about 10 to 15 degrees with respect to the vertical surface. The air is prevented from diffusing outward by the air flow A induced by the indoor air blown downward from both sides of the suction port 9 and sucked into the first duct 7 from the suction port 9 opened forward in the upward direction. . The reason why diffusion is prevented by the induced air flow A is that the periphery of the induced air flow A becomes a negative pressure region and attracts the surrounding air.

  The kitchen cabinet 1 has a slit-like heat exhaust port 18 at the rear part of the top plate 4, and may diffuse steam and oily smoke, but the influence of the exhaust heat flow from the heat exhaust port 18 due to the induced air flow A Can be reduced. Then, the polluted air sucked into the first duct 7 is exhausted from below the floor through the duct by the air blower 11 provided in the kitchen cabinet 1. Even when two or more induction heaters 3 are used, the two air outlets 13 through which the induced air flow A is blown out are at positions covering the entire width of the top plate 4, and thus are generated in the same manner as described above. Vapor and smoke are exhausted outside without spreading.

  The air blower 11 connected to the first duct 7 may be installed under the floor as shown in FIG. 9 or outdoors as shown in FIG. 10. Has the effect of increasing the degree. Moreover, as shown in FIGS. 11 to 13, the kitchen ventilation device may be installed separately from the kitchen cabinet 1 and arranged in the kitchen cabinet 1.
