Definitions

  • the present invention relates to a microwave oven, and more particularly to a door for a microwave oven.
  • a microwave oven is an appliance that cooks or heats food laid in a cooking chamber using microwaves that are generated by a magnetron disposed in a machine room.
  • the microwave oven cooks or heats the food using a frictional heat produced between moisture molecules of the food, and generated by irradiating the microwaves into the cooking chamber. That is, the microwaves repeatedly change the molecular arrangement of moisture contained in the food to cook the food.
  • FIG. 1 shows a perspective view of a conventional microwave oven with its door 8 opened.
  • the microwave oven comprises a housing 1 having a machine room 2 and a cooking chamber 3 which are partitioned from each other in the interior of the housing 1.
  • a magnetron 4 which generates microwaves, and a blower fan 5 which cools the magnetron 4 and discharges moisture and odor generated from food to the outside of the microwave oven are mounted in the machine room 2.
  • the blower fan 5 discharges the moisture and odor by circulating air through the cooking chamber 3.
  • the cooking chamber 3 is constructed in a form of a box with its front opened.
  • the cooking chamber 3 has a rectangular bottom 3a, a front end of which is laid on the same plane as a front of the cooking chamber 3.
  • a turntable 6 which allows the food to be laid thereon, and a rotation guide (not shown) which rotatably supports the turntable 6 are mounted on the rectangular bottom 3a.
  • the turntable 6 is rotated at a relatively low speed while being coupled to a motor (not shown) disposed under the cooking chamber 3.
  • the door 8 is rotatably hinged to one side of the housing 1 in front of the cooking chamber 3 so as to selectively open and close the cooking chamber 3.
  • the door 8 is constructed in a form of a rectangle.
  • a see-through member 9 having a plurality of see-through holes is fitted into a center portion of the door 8 to allow a user to see through the door 8.
  • the door 8 including the see-through member 9 has planar front and back surfaces. Accordingly, where the door 8 is tightly closed, the planar back surface of the door 8 comes into close contact with the front of the cooking chamber 3, and the front of the door 8 constitutes a plane.
  • the microwaves generated by the magnetron 4 are irradiated into the cooking chamber 3, and simultaneously, the turntable 6 is rotated at a relatively low speed. Accordingly, the food laid on the turntable 6 is cooked by the irradiated microwaves.
  • the conventional microwave oven having the construction as described above is shaped in a form of a hexahedron and the see-through member 9 formed to allow a user to see through the door 8 constitutes a plane along with the frame of the door 8, the user has to observe the interior of the cooking chamber 3 with his eyes being level with the see-through member 9. That is, the user must adjust his/her body toward and directly in front of the see-through member 9 to ascertain a cooking status of the food.
  • the door 8 of the conventional microwave oven and the see-through member 9 thereof are planar, and a region where the see-through holes are formed is small as compared to the overall size of the door 8. Therefore, the user has to approach the see-thorough member 9 to observe the interior of the cooking chamber 3.
  • the conventional microwave oven is inconvenient and time-consuming for the user to ascertain the cooking status of the food being cooked in the cooking chamber. Therefore, the user cannot carry out other tasks and must remain attentive to the microwave oven while cooking the food with the conventional microwave oven.
  • the conventional microwave oven has a planar door 8, so air fed into the cooking chamber 3 through air inlet holes (not shown) formed on one sidewall of the cooking chamber 3 is brought into collision with an inside surface of the planar door 8. Consequently, moisture generated from the food, for example, at the time of cooling, condenses on the inside surface of the planar door 8. Therefore, the user has a further difficulty in making a visual contact with the cooking chamber 3 through the planar door 8.
  • US-A-3 991 295 discloses a microwave oven in which the heating chamber is defined by an upper portion serving as a door opening upwards and a lower portion forming the oven chamber lower portion for constituting, upon closure of the door, one complete heating chamber.
  • the heating chamber In one side of the heating chamber a microwave assembly and stirrer members are provided. The stirrer members can be rotated by the passage of cooling air for efficient microwave energy distribution and consequent uniform heating of the object to be heated.
  • EP-A-0 723 382 discloses a microwave oven comprising an oven cavity, a microwave radiation source for feeding microwaves to the cavity, and an oven door with a window. Mist formation on the inside of the window is prevented by an air stream directed thereto.
  • JP 01 184 332 A discloses a cooker with a door formed in the shape of a rectangular with a punching screen arched laterally.
