The suction port 31b protrudes slightly above the top surface 20a of the cooking table main body 20 by a small amount (for example, 5 to 10 mm), so that it can be sucked downward and spilled or dusted during cooking. Or the like can be prevented from entering the circulation vent 31. Similarly to the blowout port 31a, the suction port 31b may be provided with a lattice, a wire net, or the like to prevent foreign matters such as food from entering the circulation vent 31.

  The blower 32 employs a centrifugal type or an axial flow type, and in this example, an ON / OFF operation and an air blowing amount (air blowing strength) can be adjusted by an operation switch provided on the operation panel 23b. The ON / OFF operation of the blower 32 may be linked to the ON / OFF operation of the heating cooker 23 in addition to this. The adjustment of the air flow rate is performed by increasing or decreasing the number of rotations of the motor of the blower 32. In this example, only one blower 32 is arranged in the middle of the circulation vent 31, but the blower dedicated blower arranged on the downstream side of the circulation vent 31 and the upstream of the circulation vent 31. There is also an aspect constituted by two blowers dedicated to suction arranged on the side.

In this example, the cleaning device 33 is arranged on the upstream side to capture liquid components and solid components. And an adsorber made of activated carbon, silica gel, or the like that is disposed downstream and adsorbs odors and moisture, and is arranged so that maintenance inspection and replacement can be performed below the cooking device 23. . The cooking table 10 of the present embodiment is provided with the cleaning device 33 on the upstream side of the blower 32 to reduce the adhesion of liquid components and solid components to the blower 32.

  The airflow guide plate 34 is formed of a metal plate, an opaque heat-resistant resin plate or glass plate, or a transparent or translucent heat-resistant resin plate or glass plate that can be visually recognized by the cook from the back dining area D side. The The arrangement location of the airflow guide plate 34 is on the upper surface 20a side of the countertop main body 20 and on the back side of the suction port 31b, and is fitted to a standing tool 34d provided at the arrangement location. It is erected so as to be detachable. In addition to this, the airflow guide plate 34 may be standing upright with a screw that can be turned by hand so that the back surface 40b of the counter 40 is in close contact with or close to the back surface 40b of the airflow guide plate 34 so as to be detachable. Good. As described above, the airflow guide plate 34 is detachable so that it can be easily cleaned by removing it and washing it. In addition, the standing tool 34d of this example is provided with a holding tool made of a spring, a pressing screw, or the like, thereby facilitating the fitting and removing work of the airflow guide plate 34.

  The airflow guide plate 34 is a plate having a longitudinal direction (left and right direction) dimension substantially the same as or larger than the longitudinal direction (left and right direction) dimension W2 of the suction port 31b, and an upstanding region 34a standing from the root side; A direction changing area 34b that extends from the standing area 34a and bends is formed, and the air blown obliquely upward toward the upper side of the heating cooker 23 from the outlet 31a is captured by the direction changing area 34b, and air The advancing direction is changed downward and guided to the standing area 34a. In this example, as shown in FIG. 3A, the airflow guide plate 34 is exposed by the height H on the top plate upper surface 20a side, and the tip 34c protrudes to the near side by the dimension X from the standing region 34a. Thus, the air blown from the blowout opening 31a at the elevation angle θ is brought into contact with the direction changing area 34b so as not to flow over the airflow guide plate 34 to the dining area D. Further, in this example, the airflow guide plate 34 has a total of 90 ° of the bending angle δ formed by the imaginary straight line extending from the boundary 34e between the standing region 34a and the direction changing region 34b to the tip 34c and the horizontal line, and the elevation angle θ. (Δ + θ <90 °), so that the ventilation air blown out at the elevation angle θ is captured by the direction change region 34b and along the direction change region 34b, so that the upright region 34a can be smoothly lowered. It is possible to change the direction to guide. Further, the airflow guide plate 34 is bent so that the direction changing area 34b is convex upward, so that the direction changing area 34b can easily catch the ventilation air. Thus, the airflow guide plate 34 of this example has a shape suitable for guiding the ventilation air from the tip 34c side to the suction port 31b side.

  If the airflow guide plate 34 can be bent so that the bending angle δ of the direction changing region 34b can be changed, the airflow guide plate 34 can be easily guided according to the elevation angle θ and the wind speed of the ventilation air blown out from the suction port 31b during use. It can be deformed into a shape and can be bent and compacted when not in use. The airflow guide plate 34 is formed of a plate material that plastically deforms the direction change region 34b, as shown in FIG. 3A, or shown in FIG. In this manner, the direction changing region 34b is formed by a plurality of strip-shaped plates 36, and the strip plates 36 are connected to each other by hinges 37 that can be folded and maintain a folding angle. The sheet direction changing region 34 b and the standing region 34 a may be connected by a hinge 37.

  Further, the airflow guide plate 34 can change the height H exposed to the upper surface 20a side, so that the direction changing region 34b can be adjusted to an optimal height position according to the elevation angle θ of the ventilation air and the wind speed. When the cooking device 23 is not used, the height H can be lowered so as not to stand out. In order to make the height H extendable, the airflow guide plate 34 can be freely inserted into and removed from the inside of the cooking table body 20 as shown in FIG. It is inserted to keep the height H low, and conversely, the standing area 34a can be extracted from the inside of the cooking table main body 20 so that the height H can be kept high, or as shown in FIG. It is formed of two sheets of plate materials 38, 38 so that the overlap margin can be adjusted.

  The ventilation device 30 is provided with an air volume adjuster 35a composed of a damper or the like in the middle of the exhaust passage 35. By opening and closing the air volume adjuster 35a, the air flow is exhausted from the exhaust passage 35 and blown to the outlet 31a. The distribution with the air volume can be adjusted.

  Next, operation | movement of this invention cooking stand 10 is demonstrated based on operation | movement when collect | recovering the contaminated air which generate | occur | produced during the heating cooking with the said heating cooker 23. FIG. When the blower 32 is activated during cooking, the cooking table 10 of the present invention is blown from the blower 32 and then returned to the blower 32. A discharge airflow indicated by an arrow B discharged to the outside and an intrusion airflow indicated by an arrow C entering from the outside of the cooking table body 20 are formed.

  After the circulating airflow A is blown from the blower 32, the circulating airflow A is blown out in a band shape from the rectangular outlet 31a, passes over the heating cooker 23, is captured by the direction changing region 34b of the airflow guide plate 34, and changes its direction. Then, the air is guided to the standing region 34 a, is sucked into the suction port 31 b by the suction force of the blower 32, and is repeatedly circulated through the cleaning device 33 of the circulation vent 31 and blown by the blower 32. In addition, since the momentum of the updraft produced by heating is weak when this invention cooking stand 10 employ | adopts IH type, an electric type, etc. as the heating cooker 23, a blowing wind speed is comparatively low with 1-3 m / s. The ventilation air blown out from the outlet 31a can pass through the upper portion of the heating cooker 23 without being obstructed by the rising airflow in a band shape. When employed, since the momentum of the updraft generated by heating is strong, the blowing air speed is made higher than that in the case of the IH type or the electric type, and the ventilation air blown out from the blowout port 31a is kept in a band shape in the heating cooker 23 A strong ascending air current can be guided to the air current guiding plate 34 while passing above the air. The cooking table 10 of the present invention can cause contaminated air generated during cooking to join the circulating airflow A flowing in a strip shape above the cooking device 23 and suck it into the suction port 31b. When the circulating airflow A passes above the heating cooker 23, it is pushed by the contaminated air generated and raised during cooking, and its traveling direction is slightly changed upward. In addition, the cooking table 10 of the present invention can be reused as ventilation air by purifying the contaminated air joined to the circulating airflow A with the cleaning device 33.

  The exhaust air flow B is exhausted from the blower 32 to the outside of the cooking table body 20 through the exhaust passage 35. The intruding airflow C is fresh air that is sucked into the suction port 31b as an airflow other than the circulating airflow A so as to balance the exhaust airflow B with the airflow, and the circulating airflow between the outlet 31a and the suction port 31b. Join A.

  The cooking table 10 of the present invention can adjust the distribution of the airflows of the circulating airflow A and the exhausted airflow B by opening and closing the airflow adjuster 35a of the exhaust passage 35. Specifically, when the air volume adjuster 35a is opened, the airflow of the discharged airflow B is increased by an appropriate amount, the airflow of the circulating airflow A is decreased by an appropriate amount, and the airflow adjuster 35a is closed. As a result, the air volume of the discharged air flow B is reduced by an appropriate amount and the air volume of the circulating air flow A is increased by an appropriate amount.

  Since the cooking table 10 of the present invention has a configuration in which the airflow guide plate 34 having a small cross-sectional area is provided on the upper surface 20a side of the cooking table body 20, it is possible to make the upper surface 20a side of the cooking table body 20 wider than before. It is possible to improve the workability of cooking. In addition, the cooking table 10 of the present invention causes a large amount of contaminants such as oily smoke contained in the contaminated air to come into contact with the exposed surface of the airflow guide plate 34, but because the adhered surface of the contaminant is an exposed surface, Easy to clean. In addition, when the airflow guide plate 34 is detachable, it can be easily cleaned by washing the removed airflow guide plate 34 or the like. Further, the cooking table 10 of the present invention can form the above-described airflow guide plate 34 in a shape suitable for induction of ventilation air, and can efficiently collect the ventilation air and guide it to the intake port 31b. It is also possible to reduce 31b. Furthermore, the cooking table 10 of the present invention can directly catch the scattering of oily smoke or the like generated during cooking by the airflow guide plate 34 and prevent it from scattering to the dining area D.
