Description

  The present invention relates to a range hood that exhausts oily smoke and water vapor generated during cooking to the outside.

  The environment surrounding the kitchen today is that the use of IH cooking heaters is increasing due to the increase in all-electric houses and the safety of using no fire and no generation of combustion gases such as carbon monoxide. As a part of it, an inconspicuous and harmonious design is required, and thin range hoods are becoming mainstream.

  In addition, in a conventional range hood provided with a movable hood, for example, as in Patent Document 1, a supply airflow is blown from the tip of the movable hood to induce oil smoke generated during cooking to an exhaust port, and an air curtain is formed in front of the hood. There was something that increased collection.

Japanese Patent Laid-Open No. 3-129231

  In order to match the trend of the range hood, when specializing in thinness without reducing the originally required collection performance, in the range hood with air supply and movable hood, the movable mechanism of the hood and the flow path of the air supply are There is a problem that it must be compact and have excellent design.

  In addition, when the IH cooking heater is used, there is a problem that oil smoke and water vapor diffuse because there is little heat generation and no upward air flow, and the conventional range hood cannot prevent the lateral diffusion.

  In addition, there is a problem of dew condensation on the wall surface to which the range hood is attached, particularly when the IH cooking heater grill is used in winter.

  The air supply that should increase the collection efficiency blows the air in the kitchen room through the range hood from below the range hood, that is, from above the food being cooked, which may cause discomfort from a hygienic viewpoint.

  An object of the present invention is to solve at least one of the above-mentioned problems and to realize a thin range hood with good collection performance.

  In order to achieve the above object, a range hood of the present invention includes a fixed hood provided at a lower portion of a fan unit portion in which a fan for exhaust is accommodated, a movable hood that can be stored and pulled out in the fixed hood, In the range hood having the fixed hood and the movable hood and a rectifying plate forming a suction port with the fixed hood and the movable hood, and a movable mechanism provided on a side of the fixed hood and the movable hood, the fan unit A blower that blows out air inside or outside the part, a rear box that is provided at the rear edge of the fixed hood and communicates with the blower, and a movable mechanism that is in communication with the rear box and that is lateral to the fixed hood. A fixed hood side box to be housed, and a blowout port that is provided at the lower part of the fixed hood side box and blows out the air flow blown out from the blower. That.

  According to this configuration, the hood is formed thin without newly providing a flow path, and the supply airflow is blown out from the side of the hood to prevent the lateral diffusion of oily smoke and water vapor.

  Here, the air supply outlet is not a general hole shape, but may be a gap at the joint (joint) of the box. This also improves the design.

  In addition, air supply is blown out from the rear of the fixed hood to prevent condensation water from dripping on the wall surface of the range hood.

  You may make it the supply air flow which blows off the air in a kitchen room blow off through an air purifying means. As a result, sanitary wind is obtained by sterilizing or deodorizing with charged ions, or removing dust and dust by filtering through a filter. It is even better to combine both ions and filters.

  According to the present invention, it is possible to provide a thin range hood with good collection performance.

  Embodiments of the present invention will be described below with reference to FIGS.

  The fan unit 101 of the range hood is provided with a fan 102 for discharging oily smoke, water vapor, and gas generated when cooked by an IH cooking heater to the outside. The fan 102 is driven by an exhaust motor 103. A curtain plate may be provided in front of the fan unit 101 for blinding.

  The fan 102 is covered with a scroll 104, and a bell mouth 105 is attached to the front side of the scroll 104. A filter 106 is provided in the exhaust passage on the front side of the bell mouth 105 so that oil and moisture can be collected.

This filter 106 is supported by an L-shaped support portion 107 provided on the scroll 104. With the L-shaped support portion 107 as a fulcrum, a filter 106 is disposed on the upper portion of the fan unit 101 so as to have a predetermined angle of inclination by a filter support fitting 108 using an elastic material. With these configurations, the fan 102, the bell mouth 105, and the filter 106 are detachably attached so as to be easily cleaned. In addition, a duct joint 109 for connecting a duct for discharging to the outside is attached to the outlet of the scroll 104.

The movable hood 201 has box bodies 202 and 203 assembled in a U-shape as edges. A top plate 204 that covers the entire top surface of the box body 203 is disposed, and a rectifying plate B205 that is smaller than the inner dimension of the edge of the movable hood 201 can be removed from the support portion at the same height as the lower surface of the side box body 203. Thus, the structure is attached to the top plate 204.

  One side of the side box 203 communicates with the front box 202, the other is open, and a blower outlet 206 through which a supply airflow 305 blows out is provided on the lower surface. The front box 202 also has an outlet 207 through which the air supply air 305 blows out.

  The fixed hood 208 connected to the fan unit 101 has the same configuration as that of the movable hood 201, and includes box bodies 209 and 210, a top plate 211, and a rectifying plate A212, and has a size that can accommodate the movable hood 201.

  The rectifying plate A212 is detachably attached to the supported side box 210. The side box 210 communicates with the rear box 209 provided on one side on the rear side, the other is opened, and has a gap 213 through which the top plate 204 of the movable hood 201 passes to receive the movable hood 201. On the lower surface, there is an outlet 214 through which the air supply air 305 blows out.

  The rear box 209 accommodates components such as a substrate and lighting for controlling the operation of the range hood and the like, and has a blower outlet 215 from which a supply airflow 305 blows out on the lower surface.

  As described above, in the present embodiment, each box functions as an air supply channel. Needless to say, each box need not have a so-called box shape.

  The top plate 211 has an opening 216 that communicates with the fan unit 101 when the fan unit 101 is connected. In FIG. 2, most of the opening 216 is hidden behind the rectifying plate A212.

  The movable hood 201 and the fixed hood 208 can be expanded and contracted to the box bodies 203 and 210 provided on the left and right sides of the respective hoods in the direction in which the open sides without the box bodies 202, 203, 209, and 210 that are the edges are abutted. Are connected via a movable mechanism 217.

Specifically, the box 203 on the side of the movable hood 201 is placed in the box 210 on the side of the fixed hood 208, and the top plate 204 of the movable hood 201 and the rectifying plate B 205 are placed on the top plate 211 of the fixed hood 208. It is accommodated in the fixed hood 208 via the movable mechanism 217 so as to be inserted between the rectifying plates A212.

  Here, an electric motor such as a motor may be provided as means for moving the movable hood 201 back and forth by the movable mechanism 217.

  An air supply blower 301 is provided inside or outside the fan unit 101, for example, on the top plate 211 of the fixed hood 208, and sucks and blows out air in the kitchen room, and the outlet of the supply air blower 301 is a rear box of the fixed hood 208. It is in communication with the body 209.

In addition, a device 302 that generates charged ions is disposed in the flow path of the air supply air 305, and a filter 303 that filters dust and dust in the air is provided upstream or downstream of the air supply blower 301. .

Usually, the movable hood 201 is housed in a fixed hood 208 as shown in FIG. When cooking, the movable hood 201 is pushed forward from the fixed hood 208 as shown in FIG. 3, and when the fan unit 101 is driven, the movable hood 201 is sucked into the opening 216 of the top plate 211 of the fixed hood 208 communicating with the fan unit 101. A flow is generated. Then, a negative pressure is generated between the top plates 204 and 211 of the movable hood 201 and the fixed hood 208 and the rectifying plate B205 and the rectifying plate A212. From the gap between the rectifying plates 205 and 212, oil smoke and water vapor are sucked in and exhausted to the outside.

  At this time, the air supply blower 301 is also driven alone or in conjunction with the drive of the fan unit 101, and flows into the rear box 209 of the fixed hood 208 that communicates the air sucked from the kitchen room. The air that has flowed into the rear box 209 flows into the communicating box 210 and blows downward from the blowout opening 214 toward the bottom of the range hood, so that it is possible to prevent the spread of oily smoke and water vapor generated by cooking in the lateral direction. is there.

  In the rear box 209, which is the flow path of the air supply air 305, electrical components such as a substrate and lighting are housed. These provide resistance to the flow of the air supply air 305, and the air supply air 305 may scatter dust and dust and adversely affect electrical components. It is desirable that the partition wall 304 is vertically or horizontally separated by a partition wall 304 that is a partition member formed of a plate material or sheet made of metal, plastic, or the like.

  Further, since the fixed hood 208 side of the box 203 on the side of the movable hood 201 is open, it communicates with the air supply flow path in the box 210 on the side of the fixed hood 208. Therefore, the air flow 305 flowing from the box 210 of the fixed hood 208 is blown downward from the air outlet 206 provided at the lower part of the side box 203 of the movable hood 201 to the lower side of the range hood. Therefore, since the air supply air 305 is blown from the side not only from the fixed hood 208 but also from the movable hood 201, it is possible to further prevent oil smoke and water vapor from diffusing in the lateral direction.

  Furthermore, the box 203 on the side of the movable hood 201 and the box 202 on the front are in communication with each other, and the supply air flow path is provided in the front box 202, so that the supply air that has flowed to the side of the movable hood 201 is provided. The airflow 305 flows into the front box 202 and blows out downward from the blowout opening 207 provided at the lower part of the front box 202, so that forward diffusion of oily smoke and water vapor can also be prevented.

  Moreover, the blower outlet 215 is provided in the lower part of the box 209 behind the fixed hood 208 in such a direction that the air supply air 305 flows along the wall surface to which the range hood is attached. Therefore, the range hood in this embodiment can prevent oil smoke and water vapor from adhering to the wall surface. Especially when the grill of IH cooking heater is used, the oil smoke and water vapor outlets are close to the wall surface, so it is easy for problems such as dirt on the wall surface due to oil and dripping of condensed water due to water vapor in winter. It can be prevented.

  The air outlets 206, 207, 214, and 215 of the air supply airflow 305 provided in the lower part of the box bodies 202, 203, 209, and 210 emit a wind like a curtain, so that they have, for example, a long hole shape or a continuous hole. It may be provided. Moreover, it is good also as a blower outlet by using the seam (joint) 701 formed when forming the box bodies 202, 203, 209, 210, and providing a gap with a width suitable for blowing out the wind. By doing this, it is possible to easily form a continuous outlet with a uniform width, make it easier to blow out the wind, and make it less noticeable in design than a long hole or a hole that is continuously opened. You can also.

  In addition, since the flow path of the air supply air 305 includes one or more devices 302 that generate charged ions, by generating ions alone or in accordance with the drive of the air supply blower 301, It is possible to inactivate bacteria, odors and the like floating in the air supply air 305.

  Moreover, since the filter 303 which filters the air of the supply airflow 305 is provided in the upstream or downstream of the supply air blower 301, the dust, dust, and odor which float in the air can be removed. It is preferable that the filter 303 can be easily replaced. Since the ions and the filter are used individually or in combination, the air supply 305 is always clean and does not cause discomfort even if it blows over the food being cooked.

  According to the embodiment of the present invention, the range is provided with a movable hood that is thin and excellent in design, can suppress the diffusion of oily smoke and water vapor, can prevent the condensation from dripping, and is hygienic. Can provide food.
