Definitions

  • the present invention relates to a drawer type cooking device in which a heated object storage unit can be drawn out of a heating chamber formed within a cooking device body by an operation of a door.
  • FIG. 6 is a perspective view of a drawer type cooking device equivalent to the one previously proposed by the present applicant.
  • a heating chamber 3 for cooking an object to be cooked (an object to be heated) is formed within a cooking device body 1 .
  • a drawer body 2 includes a door 2 a for opening and closing the heating chamber 3 , and a heated object storage unit 2 b that is shaped like a container on which an object to be cooked can be loaded.
  • the drawer body 2 is slidably disposed within the cooking device body 1 by a sliding mechanism 4 , so that the drawer body 2 can be drawn out forward from the heating chamber 3 of the cooking device body 1 , or can be pushed into the heating chamber 3 .
  • the sliding mechanism 4 is disposed at least on the right and left outer surfaces of the heating chamber 3 , but may be also disposed on the bottom surface thereof. Since the sliding mechanism 4 is disposed outside the heating chamber 3 , the heating chamber 3 can provide a wide space inside itself as the heated object storage unit 2 b . It is also not necessary to use an expensive component or material having high heat resistance and flame resistance for a movable rail, a fixed rail or the like, which constitute the sliding mechanism 4 . Furthermore, there is no risk that the sliding mechanism 4 is affected by microwaves emitted in the heating chamber 3 and an electric discharge occurs due to the microwaves. A wired door glass 10 as a transparent plate for blocking the microwaves is fitted into the door 2 a such that a user can look into the heating chamber 3 from the outside when the door 2 a is closed.
  • the sliding mechanism 4 includes the fixed rail that is fixed to the cooking device body 1 , and the movable rail that is mounted on the door 2 a to slide along the fixed rail.
  • the drawer body 2 is slidably supported on the cooking device body 1 via the door 2 a and the sliding mechanism 4 .
  • a DC motor for example, is provided as a driving mechanism to drive the sliding mechanism 4 .
  • a pinion that is rotated upon receiving a rotation output of the DC motor meshes with a rack that is mounted on the movable rail. When the pinion is rotated, the rack is moved linearly, so that the drawer body 2 is automatically driven via the sliding mechanism 4 .
  • the drawer body 2 can be thereby automatically drawn out and pushed in, which is especially preferable in a large cooking device.
  • the heated object storage unit 2 b has side walls on its right and left sides, and a back wall on its back side that is disposed inside the heating chamber 3 of the cooking device body 1 .
  • the heated object storage unit 2 b has an opening on its upper side, through which an object to be cooked can be put in and removed.
  • the door 2 a is mounted on the front of the heated object storage unit 2 b .
  • An operation unit 9 for allowing a user to open and close the door 2 a is provided on the upper side surface of the cooking device body 1 .
  • the operation unit 9 has an operation button, a control unit, and a display unit 5 for displaying operation contents.
  • the kitchen apparatus is a drawer type cooking device such as a microwave oven whose heating chamber can be drawn out forward.
  • the air flowing into the heating chamber engulfs water vapor generated when an object to be cooked is heated, rises as moving forward within the heating chamber, and flows into an upper horizontal duct of the cooking device body 1 .
  • the air moves backward through the horizontal duct extending across the ceiling of the heating chamber, and then moves downward to a lower portion of the back surface of the cooking device body. After that, the air moves forward on the bottom surface of the cooking device body, and is exhausted from the exhaust unit in a lower portion of the front surface of the cooking device body.
  • the supplied air sucked into the cooking device body is delivered into the heating chamber from the back surface of the heating chamber as described above.
  • An air including the water vapor generated from the object to be cooked flows with the supplied air flow to flow toward the inner surface of the door that is disposed at the front.
  • the water vapor comes into contact with the door glass and is cooled to cause condensation and adhesion of water droplets.
  • the door glass is easily fogged up. Unless the water vapor generated from the object to be cooked is prevented from coming into contact with the door glass by changing the water vapor flow, it is very difficult to prevent the fogging of the door glass.
  • An object of the present invention is to provide a drawer type cooking device which enables a user to easily check the inside of a heated object storage unit from the outside through a door glass even when an object to be heated as an object to be cooked is cooked and water vapor is thereby generated, by preventing the water vapor of the object to be cooked from being cooled in contact with the inner surface of a door to cause condensation and adhesion of water droplets, with an air curtain effect of outside air flowing along the inner surface of the door.
  • the drawer body capable of being drawn out of and pushed into the heating chamber formed inside the cooking device body includes the heated object storage unit capable of storing the object to be heated, and the door integrally mounted on the front end of the heated object storage unit.
  • the heated object storage unit is stored in the heating chamber, and the door can close the opening of the heating chamber.
  • the drawer type cooking device may further include a splash cover disposed with a gap between the splash cover and a ceiling wall of the heating chamber, wherein the air flow is guided to an upper portion of the inner surface of the door through the gap.
  • the outside air delivered into the heating chamber from the back surface upper portion flows toward a front surface of the cooking device body through the gap formed between a top surface of the splash cover and a ceiling surface of the heating chamber, and further flows as the descending air flow along the inner surface of the door glass from a front end of the splash cover.
  • a front end of the splash cover may occupy a position adjacent to the inner surface of the door, thereby forming a gap between the front end of the splash cover and the inner surface of the door to allow the descending air flow to flow down therefrom. Since the front terminal of the splash cover can be located at the position adjacent to the door, the air flow delivered into the heating chamber can be reliably caused to descend along the inner surface of the transparent plate from the gap formed between the front end of the splash cover and the inner surface of the door.
  • the drawer type cooking device has the aforementioned configuration. Therefore, in the cooking device in which the air is supplied into the heating chamber from the back surface of the heating chamber due to installation conditions specific to a large cooking device in which the drawer body is slid relative to the cooking device body by the sliding mechanism outside the heating chamber, the supplied air is caused to descend along the transparent plate despite the shape of a container of an object to be cooked, and the transparent plate can be shielded from the water vapor generated from the object to be cooked, thereby preventing fogging of the transparent plate during cooking.
  • the splash cover mounted in the cooking device to facilitate cleaning inside the heating chamber is used, the splash cover is provided with a function of preventing the fogging of the transparent plate during cooking by guiding the supplied air to flow as the descending air flow.
  • FIG. 1 is an explanatory view illustrating an air flow in a vertical section of a drawer type cooking device
  • FIG. 2 is an explanatory view illustrating an air flow in a horizontal section of the drawer type cooking device shown in FIG. 1 ;
  • FIG. 3 is a front view of the drawer type cooking device shown in FIG. 1 ;
  • FIG. 5 is a schematic plan view of the drawer body shown in FIG. 4 ;
  • the cooking device may have the same configuration as that of a conventional cooking device shown in FIG. 6 except for an exhaust air flow, and thus, the description of the configuration will be omitted.
  • a high-voltage transformer 12 for generating a high voltage, a cross-flow fan 13 , and a magnetron 14 for generating microwaves based on the high voltage from the high-voltage transformer 12 are disposed sequentially from the bottom to the top in the rear space 11 of a heating chamber 3 of the cooking device body 1 .
  • a waveguide tube 15 connected to the magnetron 14 to guide the microwaves extends across a ceiling 16 of the cooking device body 1 .
  • a splash cover 17 for facilitating cleaning inside the heating chamber is provided in an upper portion of the heating chamber 3 , that is, in the vicinity of the ceiling 16 of the cooking device body 1 .
  • the splash cover 17 is wide enough to cover substantially an entire wall surface 16 a of the ceiling 16 , and is disposed at a predetermined distance from the wall surface 16 a of the ceiling 16 . Accordingly, a gap passage 18 is formed between the ceiling wall surface 16 a and a top surface 17 a of the splash cover 17 .
  • the splash cover 17 also extends to the vicinity of the inner surface of a door 2 a .
  • a gap 19 is thereby formed between a front end 17 b of the splash cover 17 and the inner surface of the door 2 a .
  • the exhaust window unit 21 may be formed between the bottom portion 20 and the inner surface of the door 2 a by cutting away the front end of a bottom plate which constitutes the bottom portion 20 .
  • the exhaust window unit 21 also includes an upright wall 23 that stands at the edge along the exhaust window 22 in the heated object storage unit.
  • the upright wall 23 can effectively guide passage of the descending air flow, and smoothly exhaust the descending air flow including water vapor through the exhaust window unit 21 .
  • water overflowing from a food (an object to be heated) into the heating chamber 3 can be prevented from flowing out from the exhaust window 22 .
  • the air flow delivered into the heating chamber 3 from the back surface becomes an air flow F 5 , and flows forward through the gap passage 18 between the ceiling wall surface 16 a and the top surface 17 a of the splash cover 17 .
  • the air flow F 5 passes through the gap 19 formed between the front end 17 b of the splash cover 17 and the inner surface of the door 2 a , and flows as a descending air flow F 6 along the inner surface of the door 2 a . Since the descending air flow F 6 flows along a door glass 10 as a transparent plate, water vapor (a flow Fs 1 ) generated from the object to be heated during cooking is prevented from coming into contact with the door glass.
  • the descending air flow F 6 flowing along the inner surface of the door 2 a engulfs the water vapor generated from the object to be heated, and flows into the exhaust window unit 21 in the bottom portion 20 of the heated object storage unit 2 b (a water vapor flow Fs 2 ).
  • the descending air flow F 6 further passes through the exhaust opening 26 in the body bottom portion 25 of the cooking device body 1 and the exhaust duct 36 in the front surface of the cooking device body 1 , and is exhausted to outside the cooking device as an exhausted air flow F 7 from the exhaust unit 33 of the grill in the front surface lower portion of the cooking device.
  • a built-in cooking device has a smaller degree of freedom in an air supply and exhaust passage structure in comparison with a cooking device that is installed alone on a countertop or an OTR (over the range) cooking device that is mounted on a wall surface or suspended from a cabinet to be installed above a gas range. It is thus necessary to supply and exhaust air from the air supply and exhaust grill disposed in the front surface lower portion.
  • the air supply and exhaust structure is inventively disposed to address such limits, and the air can be exhausted to outside the cooking device from the front surface lower portion of the cooking device.
  • the exhaust passage from the heating chamber is reduced in length, and has less bent portion. Therefore, the blowing load on a cooling fan motor is reduced, and power consumption is thus reduced, which is preferable in view of energy saving.
