Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an exhaust device for cooking smoke, water vapor, evaporating oil, etc. by an electric, gas range or electromagnetic cooker.
[0002]
[Prior art]
Conventionally, an air intake for smoke emission is opened above the range cooker without a suction hood on the inner surface (in the vertical surface) of the rear wall of the cooking table, and is released from the outer surface of the wall through the downward duct to the atmosphere by the exhaust fan. The air was exhausted (Japanese Patent Application No. 2001-170468, Japanese Patent Application No. 2000-354713: JP-A No. 2002-162080).
[0003]
However, when it is opened on the inner surface of the wall, a considerable suction force is required to cleanly suck smoke, water vapor, evaporated oil or the like that rises from the cooking table or is directly above the air intake port that is opened on the inner surface of the wall.
[0004]
Therefore, it is an effective method by installing a wind exhauster through the vacuum box on the floor side of the downward duct to increase the suction force, but the diameter of the downward duct is relatively small, so the inner surface of the wall It has now been difficult to increase the suction power of cooking exhaust at the intake opening.
[0005]

[0007]
DETAILED DESCRIPTION OF THE INVENTION
A cooking table 13 is arranged on the floor 16 in contact with the inner surface of the wall 14 of the kitchen, and an electric range, a gas range, an electromagnetic range or the like 13 ′ is arranged on the upper surface of the cooking table 13.
[0008]
As shown in FIG. 3, a rectangular through hole 15 is formed in the wall 14 above the range 13 ′, and the through hole 15 is opened above the back surface of the cooking table 13. 8 is fitted into the through-hole 15 from the outside.
[0009]
Further, a stainless steel rectangular inner cylinder 9 is detachably inserted into the inner surface of the intake cylinder 8 from the inner end opening of the intake cylinder 8 from the inside of the through hole 15, and is fitted to the inner end of the inner cylinder 9. A rectangular frame-shaped decorative flange 9 ′ is provided, and the heat radiating gallery 10 is detachably fitted into the flange 9 ′ from the inside.
[0010]
The outer end of the rectangular air intake cylinder 8 is integrally formed by welding on the side plate 2 near one end of the stainless steel rectangular box 1 in contact with the outer surface of the wall 14, and the rectangular shape of the side plate 2 is formed inside the intake cylinder 8. A suction port 3 is drilled to allow the side plate 2 near one end of the rectangular box 1 to communicate with the intake cylinder 8.
[0011]
An air suction guide guide 4 is provided in the rectangular suction port 3 so as to protrude inside the side plate 2, that is, inside the rectangular box 1, and a gap W is interposed between the guide 4 and one end face 1 ′ of the box 1. Thus, a space 5 is provided in the interval W portion.
[0012]
As shown in FIGS. 3 and 4, the guide 4 can be a rectangular air suction guide tube 4 ′. In FIG. 4, one end outer surface 4 ″ of the tube 4 ′ and one end surface of the rectangular box 1 (more specifically, one end inner surface). ) To provide a space 5 with a gap W therebetween.
[0013]
However, the guide 4 is not limited to the rectangular guide tube 4 ′, and may be a gate-shaped guide 4 that lacks one end surface 4 a on the other end side of the rectangular box 1.
[0014]
The space 5 can be communicated between the inner end 4b of the guide 4 and the side plate 1 ″ facing the inner end 4b to form a communication space 5 ′ (FIG. 1 (B)).
[0015]
The heat radiating gallery 10 to be detachably fitted inside the rectangular frame-shaped decorative flange 9 'is made of stainless steel, and as shown in FIGS. 3 and 4, the opening frame 10' is inserted and fitted into the rectangular inner cylinder 9. A plurality of stainless steel suction guide plates 10a, 10a for heat dissipation are installed between both end plates 10 ", 10", and the opening area is reduced and adjusted by the adjusting plate 10b to adjust the air suction speed and the suction amount.
[0016]
As described above, the side surface 2, 2 ′ is in contact with the outer surface of the wall 14, and the air exhauster 6 is provided near the other inner end of the rectangular box 1 supported on the wall 14 by the intake cylinder 8. 4, the outside air inside the wall 14, i.e., the smoke for cooking, is sucked through the gallery 10, and the side plate 2 ′ of the rectangular box 1 and the other end face 1 a near the other end containing the exhaust fan 6 are exhausted to the other end surface 1 a. No. 7 is opened and smoke for cooking such as smoke, water vapor or evaporated oil from the above-mentioned range 13 'of the cooking place can be discharged together with air to the outside air.
[0017]
Further, a partition plate 11 of the rectangular box 1 is provided on the suction side of the exhaust fan 6, an air suction port 12 is provided in the center of the partition plate 11, and the other end side of the partition plate 11 is a machine room. One end side can be made an empty room.
[0018]
Further, the rectangular box 1 can be formed long in the vertical direction as shown in FIGS. 1A and 1B and long in the horizontal direction as shown in FIGS.
[0019]
Therefore, when the exhaust fan 6 is operated to suck high-temperature cooking smoke such as air, smoke, water vapor, or evaporated oil on the cooking table 13 along the guide guide 4 through the empty room, the smoke passes through the gallery 10. The heat is taken away and it cools.
[0020]
Further, the space 5 between the guide 4 and one end face 1 'of the box 1 and the communication space 5' communicating with the space 5 are significantly reduced in pressure (almost vacuum).
[0021]
Since the pressure difference between the negative pressure of the space 5 and the communication space 5 ′ and the atmospheric pressure of the cooking place is almost 1 atm, the suction amount of the cooking smoke from the gallery 10 is increased, and the upper area of the cooking table 13 is increased. The cooking smoke is sufficiently sucked and discharged from the exhaust port 7 of the rectangular box 1 to the atmosphere.
[0022]
1 (a) and 1 (b), 7 'is a downward exhaust guide cover of the exhaust port 7, 17 is a rotating shaft of the exhaust fan 6, 18 is a prime mover of the exhaust fan 6, and 19 is the gallery 10 in FIG. It is a stopper.
[0023]
【The invention's effect】
Since the present invention is constructed as described above, a rectangular air intake cylinder is opened on the inner surface of the upright wall by energizing the cooking smoke rising or staying on the cooking table by the strong negative pressure in the space in the rectangular box. Therefore, it can be easily and easily discharged into the atmosphere.
[0024]
In addition, the rectangular box can be easily mounted on the outer wall of the cooking area, and the temperature of cooking smoke can be reduced by the gallery, which is highly safe and cleans the space above the cooking table and does not require a suction hood. It can be widely used.
