Definitions

  • the present invention relates to a cooking apparatus such as a microwave oven for cooking a food stored within a heating chamber.
  • a cooking apparatus in which a gasket is formed in a hollow tubular shape so as to be able absorb an uneven clearance between a door and the edge of the opening portion of a heating chamber and thus stick the gasket closely on the edge of the opening portion; where the uneven clearance is caused by variations in the door assembly and/or by variations in the flatness deviation of the opening portion edge of the heating chamber (For example, see Japanese Patent Publication H05-26460A ).
  • the present invention aims at solving the above-mentioned problem found in the conventional cooking apparatus. And thus, it is an object of the invention to provide a cooking apparatus which not only can enhance the close contact of the gasket, that is, the sealing performance of the gasket but also can facilitate the shutting operation of the door.
  • a cooking apparatus which includes a hollow gasket for sealing between a door while shut and the edge of the opening portion of a heating chamber, wherein the gasket includes a fin-like lip formed on the outer surface thereof and extending in the longitudinal direction thereof.
  • the gasket can be closely contacted with the edge of the opening portion of the heating chamber with ease.
  • a cooking apparatus of the invention even when a clearance between the door and the edge of the opening portion of the heating chamber is uneven, steam and/or smoke can be prevented from leaking out of the door during cooking.
  • a cooking apparatus which comprises: a heating chamber for storing an object to be heated therein; a door for opening and shutting the opening portion of the heating chamber; a heating device for heating the object to be heated; and, a hollow gasket composed of an elastic member for sealing between the door while shut and the edge of the opening portion of the heating chamber, wherein the gasket includes a fin-like lip integrally formed on the outer surface thereof and extending in the longitudinal direction thereof.
  • the fin-like lip according to the first aspect of the invention is inclined inwardly with respect to the edge of the opening portion of the heating chamber. Thanks to this, not only the pressure of the interior of the heating chamber is applied to the fin-like lip but also a force is applied in a direction where the fin-like lip is raised, thereby being able to further enhance the close contact on the gasket.
  • the fin-like lip according to the second aspect of the invention is inclined outwardly with respect to the opening portion of the heating chamber. Thanks to this, in the corner portion of the gasket while mounted, the fin-like lip can be prevented from generating wrinkles therein, which makes it possible to enhance the close contact on the gasket.
  • a cooking apparatus which comprises: a heating chamber for storing an object to be heated therein; a door for opening and shutting the opening portion of the heating chamber; a heating device for heating the object to be heated; and, a gasket for sealing between the door while shut and the edge of the opening portion of the heating chamber, wherein the gasket includes a fin-like lip inclined inwardly with respect to the opening portion of the heating chamber.
  • a steam generator for supplying steam to the heating chamber. Thanks to this, the gasket prevents the steam from leaking out of the door, which makes it possible to execute steam cooking in which a large amount of steam is generated.
  • the heating device is composed of a high frequency wave supply device for heating the object to be heated directly. Thanks to this, the gasket prevents the steam from leaking out of the door, which makes it possible to execute high frequency cooking in which a large amount of steam is generated.
  • a cooking apparatus 1 composed of a microwave oven includes a heating chamber 3 for storing therein a food 2 which is an object to be heated, a door 5 for shutting the opening portion 4 of the heating chamber 3, and a high frequency wave supply device 6 which is a heating device for heating a food 2 directly.
  • a gasket 7 which is formed of an elastic material such as rubber in a substantially rectangular ring-like shape and is used to seal between the door 5 while shut and the edge of the opening portion 4.
  • the door 5 is composed of a door frame 9 and a choke cover 10 which cooperate together in constituting a choke structure for cutting off radio waves generated from the high frequency wave supply device 6, while the gasket 7 is mounted in such a manner that it is secured to the choke cover 10.
  • the gasket 7 has a tubular shape including a hollow portion 11 extending continuously in the longitudinal direction of the gasket 7, and further includes a fin-like lip 12 formed integrally on the outer surface of the gasket 7 and extending in the longitudinal direction of the gasket 7.
  • a small lip 13, which is provided on the inner peripheral side of the gasket 7, is used to seal between the door frame 9 and choke cover 10.
  • a void 14 is used to facilitate the mounting of the gasket 7 when it is produced and, therefore, the object and operation effect of the void 14 are different those of the hollow portion 11 according to the invention.
  • a clearance (which is shown by an arrow mark G), which is a portion to be sealed by the fin-like lip 12, is often uneven due to variations in the assembling operation of the door and/or due to variations in the dimensions of parts.
  • the leading end of the fin-like lip 12 is contacted with the edge of the opening portion; and, where the clearance is small, as shown in Fig. 4B, while not only the fin-like lip 12 but also the hollow portion 11 are deformed, the gasket 7 is contacted with and closely stuck on the edge of the opening portion 4. Also, where the clearance is further smaller, as shown in Fig. 4C, while the hollow portion 11 and fin-like lip 12 are both deformed greatly, the gasket 7 is contacted with and closely stuck on the edge of the opening portion 4.
  • the resilient force of the whole gasket is composed of a combination of the resilient force of the fin-like lip and the resilient force of the hollow portion.
  • an adjusting method (designing method) thereof there are known a method in which the thicknesses and shapes of the fin-like lip and hollow portion are decided selectively, and a method in which there are formed two or more series of hollow portions continuing in the longitudinal direction of the gasket. These may be designed in an optimal manner to thereby be able to secure the close contact of the gasket.
  • the hollow portions may preferably be arranged in series but, depending on the design condition or the like, they may also be intermittent.
  • a series of hollow portions may be formed air tight, whereby the elasticity of the air can be used.
  • the fin-like lip 12 formed on the gasket 7, as shown in Fig. 5A is structured such that it is inclined inwardly with respect to the opening portion 4.
  • This fin-like lip 12, when the door 5 is shut, as shown in Fig. 5B, is contacted with and closely stuck on the edge of the opening portion 4.
  • the interior of the heating chamber is in a high pressure state due to generation of steam or the like and/or due to expansion of the air caused by an increase in the temperature of the interior of the heating chamber.
  • such force as shown by an arrow mark A is applied to the fin-like lip 12.
  • the fin-like lip 12 formed on the gasket 7, as shown in Fig. 6A is structured such that it is inclined outwardly with respect to the edge of the opening portion 4.
  • This fin-like lip 12, when the door 5 is shut, as shown in Fig. 6B, is deformed in the outer peripheral direction and is contacted with and closely stuck on the edge of the opening portion 4.
  • an extrusion molding of rubber is cut to a given length and, after then, the given length of molding is formed into a ring shape.
  • the thus structured gasket 7, as shown in Fig. 2 is mounted on the door 5 substantially in a rectangular ring shape.
  • the corner portion (shown by an arrow mark R in Fig. 2) of the gasket 7 is compressed on the inside thereof and is expanded on the outside thereof when compared with the linear portion (shown by an arrow mark S in Fig. 2) of the gasket 7.
  • the present embodiment since the fin-like lip 12 is inclined outwardly with respect to the opening portion 4, the lip 12 is extendedly deformed in the corner portion of the gasket. Therefore, the elasticity of the rubber material not only can prevent the fin-like lip 12 from causing wrinkles therein but also can prevent the close contact performance of the gasket from being lowered.
  • the present embodiment can provide a gasket which is inexpensive and versatile as well as can provide a high close contact performance. Also, the radius of the corner portion of the gasket can be reduced.
  • a gasket 7 is structured such that it includes a fin-like lip 16 formed inclined inwardly with respect to an opening portion 4. This fin-like lip 16, when the door 5 is shut, as shown in Fig. 7B, is contacted with and closely stuck on the edge of the opening portion 4.
  • the interior of the heating chamber is in a high pressure state due to generation of steam or the like and/or due to expansion of the air caused by an increase in the temperature of the interior of the heating chamber.
  • such force as shown by an arrow mark B is applied to the fin-like lip 16.
  • the invention can similarly apply to a cooking apparatus in which a hinge is provided on the side portion of the door and the door can be opened and shut in the horizontal direction, or a cooking apparatus in which a heating chamber is opened upwardly.
  • the gasket in a microwave oven, when the gasket is complicated in shape, it has an ill influence on the radio wave distribution within a heating chamber and on a measure to reduce a standing wave, which requires a new measure to eliminate such influence.
  • the gasket according to the invention includes only a hollow portion and a fin-like lip, that is, it has a simple shape. Thanks to this, a new measure is not necessary and also there is provided an effect that the design of the microwave oven can be facilitated.
  • a cooking apparatus according to the invention can prevent steam and/or smoke from leaking out of the door during cooking and, therefore, it is useful as a cooking apparatus.
