JP 2001-4181 A

  In a conventional range hood such as Patent Document 1, after most of the airflow including oil smoke and water vapor rising from below collides with the current plate, the air is sucked from the intake port provided between the fixed hood and the current plate and discharged to the outside. It has a structure to do. In this structure, airflow may escape to the side of the main body, and it is required to improve the collection efficiency of oily smoke and water vapor.

  The oil smoke sucked into the intake flow passage is a phenomenon that is especially seen when the room temperature is low, but is likely to condense on the surface of the current plate. For this reason, the current plate is subjected to a surface treatment such as fluorine processing to make it easier to remove the flow plate to prevent condensation and to improve the cleanability by making it easier to wipe the surface of the current plate during normal maintenance.

  However, since the range hood is attached at a high place and the current plate itself is also large, there is a problem that it is difficult for the user to wipe or remove when cleaning.

  In addition, the exhaust port of the grill of IH cooking heater and gas stove is provided on the wall side, and when grilling fish etc. on this grill, the oil smoke and steam collide with the current plate at the rear of the range hood, Condensation is likely to occur on the back baffle plate and the rear wall surface, and if the amount of condensed water drops, it may drip into the cooking pan, etc. There was a problem that the water dripped onto the kitchen surface and it took time and effort to clean up the condensed water.

  The present invention aims to solve the above-described problems.

In order to solve the above problems, a range hood of the present invention includes a fixed hood provided at a lower portion of a unit portion having a fan for exhaust, a movable hood movable forward from the fixed hood, and the movable hood of the movable hood. a front rectifying plate which is supported on the lower, and side rectifying plate after the movable der in the direction of the front side rectifying plate from position supported below the fixed hood is, and is supported below said front rectifying plate , have a, wherein a front side rectifying plate and the rear straightening plate, those which are different levels provided in the height direction.

  According to the above configuration, since the rear rectifying plate can be moved forward from the position supported below the fixed hood, the oily smoke and water vapor that directly reach the rear rectifying plate are reduced and it becomes difficult to get dirty. Moreover, since the baffle plate approaches the front user at the time of cleaning, the cleaning property is improved.

  In addition to the above-described configuration, the range hood of the present invention may be provided with a constant interval intake port serving as an intake flow path between the front rectifying plate and the rear rectifying plate.

  According to the present invention, the amount of oil smoke or water vapor rising from below collides with the rectifying plate is reduced, the amount of suction from the intake port provided between the hood and the rectifying plate is increased, and the collection efficiency is improved. Also, the surface of the current plate is difficult to condense.

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings. 1-4, the range hood which is one Embodiment of this invention is demonstrated.

  A fixed hood 2 is provided at the lower part of the unit portion 1 provided with a mechanism for sucking indoor air from the range hood and discharging it outside.

  The movable hood 3 is supported so that it can be stored and pulled out with respect to the fixed hood 2. The unit portion 1, the fixed hood 2, and the movable hood 3 have flow paths through which oil smoke or water vapor that has been sucked and passed through the hood is introduced into the unit portion 1.

  In the unit portion 1, there are an intake passage 4 and an exhaust passage 5. The intake passage 4 is connected to the fixed hood 2 and the movable hood 3 and passes through an intake opening 7 provided at the lower part of the unit portion 1. The exhaust passage 5 reaches the outside through an exhaust port 6 provided on the upper surface of the unit portion 1.

  The exhaust fan 8 is provided with a sirocco fan 10 disposed in a scroll 9 attached to the unit portion 1. A blower mounting plate 11 is provided behind the unit portion 1 and an exhaust blower 8 is attached.

  A filter 12 is provided in the exhaust flow path 5 in front of the scroll 9. The filter 12 is supported by an L-shaped support portion 13 provided outside the scroll 9. Further, the filter 12 is disposed with an inclination of a predetermined angle by a filter support fitting 14 using an elastic material in front of the unit portion 1 with the L-shaped support portion 13 as a fulcrum.

  An oil pocket 15 for receiving oil collected in the scroll 9 by the oil collected by the filter 12 and the oil adhering to the sirocco fan 10 being blown off by centrifugal force is detachably disposed behind the fixed hood 2. ing.

  A duct joint 16 connected to a duct (not shown) leading to the outside is provided at the exhaust port 6 on the upper surface of the unit portion 1.

  A plurality of illumination mechanisms 18 are provided behind the fixed hood 2 provided in the lower part of the unit portion 1 via a cover 17 made of a light-transmitting material, for example, made of glass.

  Two (or more) front rectifying plates 19 provided below the movable hood 3 and two rear rectifying plates 20 provided below the fixed hood 2 are provided at different supported heights.

  The entire circumference of each rectifying plate between the movable hood 3 and the fixed hood 2, and the front rectifying plate 19 and the rear rectifying plate 20 is used as a suction port 21 to improve the collection efficiency.

  When the movable hood 3 is pulled out from the state housed in the fixed hood 2, a constant-interval suction port 22 that is a part of the intake flow path 4 is formed at a portion where the front rectifying plate 19 and the rear rectifying plate 20 intersect, Most of the air containing oil smoke and water vapor rising from below does not collide with the front rectifying plate 19 and the rear rectifying plate 20 but is sucked from the suction port 22 at a constant interval, so that the collection efficiency is improved. As a result, the surface of the front rectifying plate 19 is less likely to condense.

  A movable mechanism 24 is provided at a lateral position of the fixed hood 2 and the movable hood 3. The rail 25 is moved by the movable mechanism 24 (for example, pulley system: drive motor, limit switch, and wire), and the movable hood 3 is stored in the fixed hood 2 or protruded from the fixed hood 2.

  In order for the movable hood 3 to move relative to the fixed hood 2, if the main body is in an operating state, for example, when the main body switch 26 is turned on (or from an IH cooking heater equipped with a light receiving portion that receives infrared rays in the main body). When receiving an infrared signal or receiving an infrared signal from a remote control), the movable hood 3 is automatically moved or moved with respect to the fixed hood 2 (in conjunction with a signal from outside the main body).

  Each of the front rectifying plate 19 and the rear rectifying plate 20 is provided with an L-shaped hook portion 27 on one side and a spring-type claw portion 28 on the opposite side with respect to the hood above each. On the other hand, on the lower surface of the movable hood 3, a hook support fitting 29 provided with a square hole and a spring-type claw support fitting 30 are provided. For the rear flow straightening plate 20, a hook support fitting 29 provided with a square hole in a rail disposed in a box 31 on the side of the fixed hood 2 and a spring-type claw support fixture 30 are provided.

By removing the spring-type claw portion 28 on the front side of the rear rectifying plate 20 and then removing the hook portion 27 from the hook support bracket 29, the rear rectifying plate 20 can be removed from the fixed hood 2, and the reverse rectification can be achieved by attaching it in reverse. The plate 20 is supported by the fixed hood 2. Similarly, the front rectifying plate 19 can be removed from the movable hood 3 or supported. However, since the front rectifying plate 19 and the rear rectifying plate 20 are supported at overlapping positions although a space is opened, it is necessary to remove the rear rectifying plate 20 from the rear rectifying plate 20. By the above, each baffle plate is detachable from the supported hood.

The case where the range hood is washed will be described with reference to FIGS. When the “care” switch provided on the main body switch 26 is turned ON, the rear straightening plate 20 provided below the fixed hood 2 from the position normally supported by the fixed hood 2 to the front side (or obliquely downward position) It moves automatically to the lower position of the current plate 19 (even if it does not move automatically, it may be moved manually as a free state by turning on the “care” switch).

  In this case, a movable mechanism portion 24 similar to the case where the movable hood 3 is moved is provided at the lateral position of the fixed hood 2 and the movable hood 3, and the rail 37 driven by the movable mechanism portion 24 is provided with the movable hood 3. Are provided in the same box 31 as the movable mechanism 24.

  As described above, the rear flow straightening plate 20 supported below the fixed hood 2 moves from the support position to the front (or obliquely lower position) and is supported by a detachable structure. , Improved cleanability, easy to wipe and remove the surface during normal care.

Further, in FIG. 7, when the “grill mode” switch aligned with the main body switch 26 is turned ON, the rear rectifying plate 20 is automatically (or manually) moved forward (or obliquely downward).

  When a fish or the like is baked on the grill of the IH cooking heater, the oil smoke and steam are exhausted from the grill exhaust port 32 at the rear position of the IH cooking heater. However, according to this embodiment, the space leading to the intake opening 7 provided at the lower rear of the unit portion 1 is widened (see FIG. 6), and the rear rectifying plate 20 below the fixed hood 2 collides with the rear of the main body. No longer run away. For this reason, the dew condensation water does not drip into a cooking pan or the like and the cooking is not contaminated.

  In addition, oil smoke or steam exhausted from the grill exhaust port 32 of the IH cooking heater due to the Coanda effect flows in the rear wall surface 33 (in an oblique direction), and condensation may occur on the rear wall surface 33 particularly in winter. is there.

  However, even for this phenomenon, the movable hood is moved by moving the rear rectifying plate 20 in the forward direction (or obliquely downward position) below the movable hood 3 so that the amount of overlap with the front rectifying plate 19 increases. 3 The flow resistance of the intake flow path 4 below the fixed hood 2 is lower than the flow resistance of the intake flow path 4 below, and the amount of air sucked from below the fixed hood 2 toward the intake opening 7 increases.

  Therefore, the exhaust from the grill exhaust port 32 of the IH cooking heater is exhausted upward in the unit part 1 where the intake passage 4 is located, the condensation on the rear wall surface 33 is reduced, and the dew condensation water droops on the kitchen surface. This eliminates the need for cleaning work to wipe off the condensed water.

  In FIG. 8, a lighting fixture 34 for illuminating a hand during cooking is generally provided at a rear position of the main body, but the front rectifying plate 19 provided below the movable hood 3 is arranged in the front-rear direction of the movable hood 3. A short rectifying plate 35 having a length less than half of the length is provided on the rear side, and a glass 36 having a length substantially less than half on the front side with respect to the length in the front-rear direction of the movable hood 3 (single number) By attaching the sheet and a plurality of sheets), the glass 36 whose front length is approximately half or less allows the indoor light to be taken under the hood, and the hand during cooking becomes brighter.

Furthermore, the lighting fixture 34 provided in the rear position can reduce power consumption by using not only a light bulb but also an LED (or a high-intensity LED) or a fluorescent lamp, and the running cost can be reduced. When an LED having a long life (or a high-intensity LED) is used, the replacement frequency is drastically reduced as compared with the use of a light bulb or a fluorescent lamp, reducing the user's trouble and reducing the cost of the replacement lighting fixture.

  As described above, according to the description using the embodiment of the present invention, the rectifying plate provided below the fixed hood can be moved from the position provided below the fixed hood to the front and lower positions, thereby Condensation and adhesion of oil smoke and water vapor to the current plate are reduced, and cleaning is improved. In addition, the rectifying plate is made detachable so that it can be easily wiped off and removed during normal maintenance.

  Furthermore, by moving the baffle plate from the position provided on the lower surface of the fixed hood to the front and substantially obliquely downward, it is possible to efficiently collect oil smoke and steam when fish are baked on the grill of the IH cooking heater. Condensation does not occur on the current plate or the rear wall surface provided on the lower surface of the fixed hood.

  In general, lighting fixtures for illuminating the hands during cooking are provided at the rear of the main body, but the rectifying plate provided on the lower surface of the movable hood is approximately half the size behind the movable hood. In addition, by attaching one or more glasses to the front of the size of the movable hood approximately half or less, it is possible to incorporate indoor lighting from the front glass and lighten the hand during cooking .
