Definitions

  • the present invention relates to a movable hood, and more particularly, to a movable hood used for suctioning and removing contaminants floating in a room.
  • a kitchen is provided with a kitchen table on which a heating device such as an electric heater or gas range is disposed to cook food such as boiling or baking by applying high-temperature heat to food.
  • a heating device such as an electric heater or gas range is disposed to cook food such as boiling or baking by applying high-temperature heat to food.
  • the food heated by the high heat of the heating device disposed on the cooking table generates pollutants such as smoke, smell, and oil vapor in the process of being heated. These contaminants may float by heat and spread throughout the kitchen or room. Such diffused contaminants can provide an unpleasant odor and cause disgust. In particular, in an enclosed kitchen, these contaminants reduce the worker's concentration and become a factor that harms the worker's health.
  • a range hood is installed in the kitchen to discharge contaminants such as smoke, smell, and oil vapor generated during cooking to the outdoors.
  • Such a range hood may include a hood main body having an exterior appearance of a range hood and having a suction port formed on a lower surface thereof, and a blower that draws in air into the hood main body and generates airflow to discharge the air to the outdoors.
  • the range hood may further include a filter installed in the hood body to filter air sucked into the body, and a pipe passing through the filter and forming a passage through which the air sucked into the body is discharged to the outdoors.
  • Contaminants generated in the process of heating food on the kitchen counter by a heating device are raised by their own buoyancy due to a temperature higher than that of the surrounding air, or are forcibly raised by airflow generated by a blower of a range hood. Contaminants raised in this way may pass through the filter and be discharged through a pipe connected to an external duct.
  • the range hood can inhale air and contaminants near an inlet formed on the lower surface of the hood body to some extent, but it is difficult to properly inhale air and contaminants located far from the inlet. This is because the flow rate of the suction airflow decreases in inverse proportion to the square of the distance from the suction port as the distance from the suction port increases.
  • the suction performance rapidly decreases as the distance from the intake port increases, and even if the suction flow rate of the suction fan increases, the efficiency of collecting pollutants does not increase proportionally.
  • the effective air intake area of the conventional range hood is limited to a small area about the diameter of the air intake port. Therefore, conventional range hoods are not suitable for removing contaminants generated far from the intake vent.
  • a range hood using an eddy current generates eddy currents by blowing air in an amount similar to the amount of air intake into the space, and can increase collection efficiency by using the concentrated eddy currents generated in this way.
  • noise is generated due to generation of turbulent flow due to mutual interference between the flow blown out and the flow sucked in a narrow area under the intake port.
  • the vortex generated in the range hood using the vortex generates a flow blowing into the space, and this flow may cause additional diffusion of contaminants in the space.
  • the range hood has a disadvantage in that it requires the installation of additional equipment such as a blower, a filter, and a flow pipe for generating swirl.
  • the swirler is rotatably installed on the inlet side of the exhaust system.
  • a swirler is configured to include a disc-shaped rotary plate, a plurality of blades arranged on the lower surface of the rotary plate to form a vortex, and a driving motor for rotating the rotary plate.
  • the swirler configured as described above serves to expand the intake area of the exhaust device by generating a vortex around the suction port of the exhaust device during rotation.
  • the suction area of the exhaust device may further expand.
  • intake of air and contaminants located far away from the exhaust device can be performed more effectively.
  • Prior Document 1 Korean Patent Registration No. 10-2059802 discloses a range hood equipped with a vortex fan. As shown in FIG. 1, the range hood disclosed in Prior Art 1 includes a housing 200, an upper case 300, a vortex fan 400, and a lower filter case 500.

  • the vortex fan 400 is installed inside the upper case 300, and the lower filter case 500 is installed spaced apart from the lower portion of the vortex fan 400.
  • the vortex fan 400 is disposed in the separation space 460 between the upper surface of the lower filter case 500 and the ceiling surface of the upper case 300 .
  • the vortex fan 400 rotates together with the exhaust fan 210 .
  • the vortex fan 400 pushes the air in the spaced space 460 outward, and the pushed airflow flows downward along the inclined surface of the upper case 300, then the outer surface of the lower filter case 500 and the upper case ( 300) is discharged out of the upper case 300 through the exhaust space 700 between the inner surfaces.
  • a vortex is formed on the outer lower portion of the lower filter case 500. That is, a kind of low pressure zone is formed at the outer periphery of the lower filter case 500, and an ascending airflow appears at the center where the exhaust fan 210 and the vortex fan 400 are disposed.
  • the range hood of Prior Art 1 as described above is fixedly installed at a location in a kitchen, for example, on top of a sink. Such a range hood can suck in and discharge only the air around the sink where the range hood is installed to a certain extent, and it is difficult to suck in and discharge the surrounding air when cooking is performed outside the kitchen.
  • the suction power of a general exhaust fan such as the exhaust fan 210 provided in the range hood of Prior Document 1, is only as far as the diameter of the exhaust fan from the exhaust fan inlet, and the suction flow rate at the corresponding position is 1 of the intake flow rate at the exhaust fan inlet There is a physical limit that falls below /10.
  • the range of the vortex generated by the vortex fan 400 of the range hood of Prior Document 1 is very wide compared to the range occupied by the range hood. Therefore, when the range hood is installed on a dining table or kitchen space, an additional space for maintaining vortex generated by the vortex fan 400 must be sufficiently secured.
  • the range hood having the vortex fan 400 as disclosed in Prior Document 1 has an installation space restriction that it must be installed in a dining table or kitchen space while securing sufficient additional space.
  • the vortex fan 400 of the range hood disclosed in Prior Art 1 can effectively form a vortex under the condition of rotating at a specific speed. That is, when the vortex fan 400 rotates at a speed out of the appropriate range, the vortex cannot be properly formed.

  • Prior Document 1 two fans are built into one range hood. That is, the exhaust fan 210 and the vortex fan 400 are installed together inside the range hood, and the exhaust fan 210 and the vortex fan 400 are arranged in a row along the vertical direction.
  • the range hood of Prior Document 1 not only has a fairly large width due to the vortex span 400, but also has a considerably thick thickness in the vertical direction due to the two fans arranged in a row along the vertical direction.

  • Prior Document 1 the range hood of Prior Document 1 is not only difficult to use while placed on a sink or dining table due to its size, but also difficult to move due to its weight, making it virtually impossible to be used in a mobile manner.
  • the suction flow is formed to face upward. If the suction flow is formed to be directed upward, there is a high possibility that the polluted air will eventually be sucked into the range hood even if it flows out of the range hood while being sucked in.
