Description

  The present invention relates to a ventilator for exhausting polluted air such as smoke, steam and exhaust gas generated during cooking in a kitchen range to the outside.

  Conventionally, this type of ventilator is arranged above the kitchen range, sucks contaminated air generated in the range by an exhaust fan, and discharges it outside through an exhaust duct. At that time, the overhanging dimensions of the ventilator are set so that they do not interfere with cooking operations, but a movable smoke trap is installed on the front of the ventilator so that the smoke is collected even during cooking where much smoke is generated. It is known to provide a collecting cover (see, for example, Patent Document 1).

  The ventilation device will be described below with reference to FIG.

  As shown in FIG. 4, a movable smoke collection cover 103 is provided on the front surface of the hood main body 101 of the ventilation device constituted by the exhaust fan 102 and the hood main body 101, and the smoke collection cover 103 is provided with the hood main body 101.

Increased and increased the amount of smoke collected.

JP 2000-97462 A

  In such a conventional ventilator, since the suction port 104 of the exhaust fan 102 is located behind the hood body 101, the distance to the smoke collection cover 103 provided in front of the lower surface of the hood body 101 is long. Therefore, the suction wind speed decreases near the smoke collection cover 103. For this reason, even during cooking where a lot of smoke is generated, even if smoke on the rising airflow generated by the heat from the range hits the smoke collection cover 103, the suction air speed is insufficient and the exhaust fan 102 is not sucked. There has been a problem of leakage from the main body 101.

  SUMMARY OF THE INVENTION The present invention solves the above-described conventional problems, and an object of the present invention is to provide a ventilator that does not leak smoke even when a smoke collection cover is extended forward and can discharge the contaminated air in the range to the outside. .

It has the composition of having. This opens the front panel during cooking when a lot of smoke is generated, and when the partition plate is tilted into the hood body, a suction air passage from the front opening is formed, and the suction air speed in front of the hood body does not decrease. Because the smoke collected on the front panel passes through the air passage formed by the partition plate, it is sucked into the exhaust fan and discharged outside, so even when cooking where a lot of polluted air is generated, The effect is that the contaminated air collected by the front panel does not leak outside.

  In addition, a grease filter facing the lower opening and the front opening is provided so as to surround the front of the suction port of the exhaust fan in the hood body. As a result, the oil in the hood body is collected by the grease filter, ensuring that the exhaust fan does not get oil and ensuring the performance, and the mechanism that collects the oil smoke from the grease filter provides ventilation resistance. The suction air speed is made uniform at the ventilation surface, and the contaminated air is sucked in from the front opening side in the hood body, and the contaminated air collected by the front panel is prevented from leaking outside (claim 2).

  Further, side plates are provided on both sides of the front panel. Thereby, when the front panel is opened, the smoke hitting the front panel does not diffuse from the side surface of the front panel, and the collected polluted air does not leak outside (claim 3).

  In addition, a stopper is provided to hold the partition plate when it falls into the hood body, and the position of this stopper can be slid forward and backward. Thereby, the inclination which a partition plate falls by changing a stopper position changes, the suction air volume from the front can be adjusted, and it has the effect that the collection performance of contaminated air can be adjusted according to a cooking form (Claim 7). ).

  Further, a sub suction port is provided on the front side of the top surface of the hood main body. As a result, even if contaminated air from the range leaks from the hood main body, it is sucked from the auxiliary suction port, so that the collected contaminated air does not leak outside (claim 8).

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

(Embodiment 1)
FIG. 1 is an installation front half sectional view of a ventilation device according to Embodiment 1 of the present invention.

  As shown in FIG. 1, a lower opening 3 and a front opening 4 are provided below the hood body 2 of the ventilation device 1, and an exhaust fan 6 having a suction port 5 is disposed in the hood body 2. At the same time, a grease filter 7 made of a plurality of laminated lath metals is provided. The grease filter 7 has two surfaces having a substantially L-shaped cross section, one end of which is held on the rear inner wall of the hood body 2 and the other end is held on the upper inner wall of the hood body 2. . The first component surface 7 a of the grease filter 7 is positioned between the lower opening 3 and the suction port 5 so as to face the lower opening 3, and the second component surface 7 b of the grease filter 7 is opposed to the front opening 4. And located between the front opening 4 and the exhaust fan 6. The left and right side ends that are not held by the hood main body 2 are in contact with the inner walls of both side surfaces of the hood main body 2 and surround the suction port 5.

  A first air passage 8 is formed from the lower side of the hood body 2 through the lower opening 3, through the grease filter 7, and to the suction port 5 of the exhaust fan 6. Is provided with an adapter 9 to which an exhaust duct 10 communicating with the outdoors is connected.

  A front panel 11 is provided in the front opening 4 of the hood body 2. The front panel 11 has a flat plate shape, and is pivotally fixed to the hood body 2 by a rotation axis A12 provided at the upper part on both sides of the front panel 11, and is rotated by the rotation axis A12 to be in front of the hood body 2. It is configured to open. Further, on both side surfaces of the front panel 11, side plates 13 are accommodated in the hood main body 2 when the front panel 11 is closed, and cover gaps generated on both front sides of the hood main body 2 when the front panel 11 is opened. Is provided.

  Further, a partition plate 14 is provided in the hood main body 2 behind the front panel 11 of the front opening 4. This partition plate 14 is also a flat plate, and is pivotally fixed to the hood main body 2 by a rotation shaft B15 provided at the lower part on both sides of the partition plate 14, and is disposed so as to overlap the front panel 11. In a state where the partition plate 14 is almost upright, the partition plate 14 is slightly tilted to the inside of the hood body 2 so as to fall down due to its own weight. Alternatively, a coil spring (not shown) is installed on the rotation axis B15 so as to fall down.

  The hood main body 2 is provided with a stopper 16, which is held by the stopper 16 when the partition plate 14 is rotated by the rotation shaft B 15 and falls to the hood main body 2 side. And the upper side 17 of the partition plate 14 is positioned in the vicinity of the grease filter 7. The stopper 16 is made of rubber or the like, and has a buffering function when the partition plate 14 falls down. When the partition plate 14 falls down, a second air passage 18 is formed in the hood body 2 from the front opening 4 through the grease filter 7 to the suction port 5 of the exhaust fan 6.

  A switch operation unit 19 for controlling the operation of the ventilator 1 is also arranged on the front surface of the hood body 2.

  In the above-described configuration, when cooking in a range, for example, when cooking such as a kettle or the like generates little contaminated air and causes little diffusion, the front panel 11 is closed and the ventilator 1 is operated by the switch operation unit 19. When the front panel 11 is closed, the lower portion of the front panel 11 hits the lower side of the partition plate 14 and a force is applied to press the lower side of the partition plate 14. The front panel 11 is closed in the right half of the front view of FIG. 1A (shown by a broken line in FIG. 1B).

  When the partition plate 14 rotates and rises, the second air passage 18 is not formed, so that the suction surface of the first air passage 8 becomes the entire lower opening 3 of the hood body 2. Therefore, the amount of contaminated air generated by cooking from the range below the hood main body 2 is small, the amount of diffusion in the hood main body 2 is small, and is collected at the lower opening 3 of the hood main body 2 provided above the range. Then, the air is sucked by the exhaust fan 6 without leaking from the hood main body 2 and discharged to the outside by the exhaust duct 10.

  Then, when cooking is performed in the range, when the generation of contaminated air is large and the diffusion is large, the front panel 11 is opened forward, and the ventilator 1 is operated by the switch operation unit 19. When the front panel 11 is opened forward, the lower part of the front panel 11 is detached from the partition plate 14, and the partition plate 14 eliminates the support of the front panel 11, and rotates around the rotation axis B15 by its own weight or spring force (not shown). It moves and falls to the inside of the hood main body 2 and is held against the stopper 16 to form a second air passage 18.

  Since the grease filter 7 has a mechanism for collecting oil and smoke to provide ventilation resistance, and the suction air speed is uniformed on the ventilation surface, the air volume of the first air path 8 and the air volume of the second air path 18 are divided by the partition plate 14. Is tilted in the vicinity of the grease filter 7, the air is roughly divided into the ventilation area ratio between the first component surface 7 a and the second component surface 7 b of the grease filter 7. Therefore, since the front panel 11 is open, the second air path 18 configured in the hood body 2 with the partition plate 14 tilted down sucks contaminated air from the lower side of the front panel 11 with the air volume.

  According to the above configuration and operation, when the front panel 11 is opened, the suction surface of the second air passage 18 is formed in front of the lower opening 3 of the hood body 2 that is the suction surface of the first air passage 8. Therefore, the entire suction surface is enlarged. And since the partition plate 14 has divided | segmented into the 1st air path 8 and the 2nd air path 18, it is grease also in the suction area where the front panel 11 ahead of the food | hood main body 2 protruded through the 2nd air path 18, and was expanded. Compared to the suction air speed at the second component surface 7b of the filter 7, the suction air speed is not lowered and the contaminated air is sucked in, so that the collection performance is improved.

  Therefore, even when there is much generation of contaminated air when cooking in the range and the diffusion thereof is large, the lower opening 3 of the hood body 2 provided above the range and the enlarged surface below the opened front panel 11 Thus, the contaminated air is collected, and the effect that the contaminated air does not leak out of the hood body 2 can be obtained.

  Further, the side plate 13 that covers the gap formed between the front surface of the hood main body 2 and both side edges of the front panel 11 when the front panel 11 is opened prevents contamination air from leaking from the gap.

  When exhausting a large amount of polluted air generated from the range by tilting the front panel 11 forward, increasing the fan speed and further increasing the exhaust air volume will increase the suction area and the exhaust volume, More collection performance.

  Further, the grease filter 7 is made of a lath metal, but as long as the suction surface wind speed of the filter portion is made uniform, it may be a punching metal other than the lath metal, and the first component surface and the second component surface of the filter. Ventilation pressure loss may be changed. Furthermore, if the shape of the main body hood, the position of the exhaust fan, and the configuration of the partition plate, for example, if the partition plate collapses in the vicinity of the fan inlet and the air volume of the second air passage does not decrease, there is no filter. However, the intended purpose is achieved.

And as a locking means of the front panel 11, a locking hole 22 is formed on both side surfaces of the metal frame 21, and a shape projecting hemispherically toward the front panel 11 so as to fit into the locking hole 22 in the hood body 2. The locking dowels 23 are formed. In addition, a panel opening / closing handle 24 made of a heat insulating material is provided as a panel opening / closing handle at the lower portion of the metal frame 21 of the front panel 11, and a rubber packing 25 is sandwiched between the rotation axis A 12 of the front panel 11 and the hood main body 2 is fixed to the shaft. The front panel 11 can be opened and closed freely.

  On the lower side of the partition plate 14, a contact plate 26 made of a material resistant to impact such as resin is provided, and the partition plate provided on the inner peripheral frame 27 of the lower opening 3 of the hood body 2 by the rotation axis B 15 of the partition plate 14. It is fixed to the mounting hole so that it can be opened and closed. The stopper 16 has a cylindrical shape, and is formed with a groove 28 that engages with the inner peripheral frame 27 of the lower opening 3 of the hood main body 2, and the groove 28 is fitted and attached to the inner peripheral frame 27.

  In the above configuration, even if the front panel 11 is opened and the front panel 11 blocks the line of sight from the cook to the range part, the transparent plate 20 transmits the line of sight, for example, cooking in a pan in the range part The effect that the state can be confirmed is also obtained (claim 4).

  Further, when the front panel 11 is closed, the locking holes 22 are engaged with the locking dowels 23, the front panel 11 is securely fixed and locked to the hood body 2, and a rattling sound due to vibration of the exhaust fan 6 is generated. The effect of elimination can be obtained (claim 5).

  Moreover, the opening and closing operation of the front panel 11 heated by the heat generated during cooking is performed by the panel opening / closing handle 24 made of a heat insulating material, so that the opening / closing operation can be performed safely.

  And since the stopper 16 moves the upper end of the inner peripheral frame 27 of the lower opening part 3 of the hood main body 2 back and forth by the groove 28, the inclination of the partition plate 14 changes depending on the position of the stopper 16 which also serves as a buffer, and the second Since the ventilation cross-sectional area of the air passage 18 is variable, the amount of air introduced into the second air passage 18 can be adjusted, and there is an effect that the contaminated air collecting performance can be adjusted in accordance with the cooking mode (claim). Item 7).

  Note that the friction of the rubber packing 25 is used to freely open and close the front panel 11, but an oil gear or the like may be used for the rotation shaft A.
