Description

The present invention relates to microwave cooking utensils and microwave ovens.

Patent Literature 1 discloses that a container containing food to be cooked is placed in a heating chamber of a microwave oven so as to float from the bottom surface of the heating chamber.

Japanese Patent Application Laid-Open No. 2007-139226

However, the technology disclosed in Patent Literature 1 has room for improvement in appropriately controlling the heating of the food in the microwave oven according to the food.

An object of the present invention is to appropriately control the heating of food in a microwave oven according to the food to be cooked.

As used herein, the term microwave oven includes those having functions as ovens (microwave ovens) and those having functions as grills, unless otherwise specified.

One aspect of the present invention includes a plate detachably supported in a heating chamber of a microwave oven, a support mechanism provided on the lower surface of the plate, and the A container detachably supported by a support mechanism, the container being made of a cylindrical container body with a bottom made of a microwave transmitting material, and a material having a specific gravity lighter than that of the container body, and attached to the container body. and a mounting member mounted on the support mechanism.

The design of the plate, support mechanism, and container allows the distance between the bottom surface of the heating chamber and the bottom surface of the container to be set, so that the heating of the food in the microwave oven can be appropriately controlled according to the food to be cooked. Since the container includes the mounting member made of a material having a lighter specific gravity than the container body, it is possible to suppress weight increase of the container due to the provision of the configuration (mounting member) for mounting to the support mechanism.

The container body is made of glass or ceramic.

Glass or ceramic container bodies are superior to resin containers in terms of scratch resistance, lingering odor, and durability. Therefore, user convenience can be improved.

The bottom surface of the heating chamber extends in a first direction and a second direction intersecting the first direction, and the support mechanism extends in the first direction facing the bottom surface and extends in the second direction. a pair of support portions spaced apart in a direction, and the container body has a flange portion having an outer shape smaller than a distance between opposed inner ends of the pair of support portions when viewed from the first direction. The mounting member includes a resin holding member placed on the pair of support portions and placed below the flange portion to hold the flange portion, and a resin holding member placed above the flange portion. and a resin cover connected to the holding member.

Since the container body is smaller than the space between the inner ends of the pair of support parts, and the mounting members each have a holding member and a cover made of resin, the weight of the container can be reduced compared to the case where the entire container is made of glass or ceramic. Weight can be reduced. Since the mounting member made of resin can be molded by a mold, it is possible to ensure dimensional accuracy with respect to the container body and the support mechanism.

The holding member and the cover are connected by a connecting member.

Since the holding member and the cover are connected by the connecting member, the mounting member can be firmly attached to the container body. Therefore, the handleability of the container can be improved.

The holding member and the cover are engaged with a locking hole provided in one of the holding member and the cover, and a hole edge of the locking hole provided in the other of the holding member and the cover. It is separably connected with the locking piece.

Since the holding member and the cover are connected by locking the locking piece to the rim of the locking hole, a separate connecting member is not required. Therefore, it is possible to reduce the number of parts and simplify the operation of attaching the attachment member to the container body. Further, the holding member and the cover can be removed from the container main body by operating the locking piece to release the locking to the holding member. Therefore, it is possible to improve the cleanability of the container body and the mounting member.

The bottom surface of the heating chamber extends in a first direction and a second direction intersecting the first direction, and the support mechanism extends in the first direction facing the bottom surface and extends in the second direction. The container body has a pair of support portions spaced apart in a direction, and the container body protrudes from the outer peripheral portion of the container body with a uniform dimension, and when viewed from the first direction, the pair of support portions It has a flange portion having an outer shape larger than the space between the opposed inner ends, and the mounting member is made of a rubber cover that covers from the lower surface to the upper surface of the flange portion.

Since the flange portion of the container body protrudes from the outer periphery by a uniform dimension, the portion of the container body required to mount the container to the support mechanism can be minimized. In other words, the weight of the container can be reduced as compared with the case where the rectangular flange portion is formed along the support portion in the container body. Since the flange portion is covered with a rubber cover, it is possible to prevent the container body from being damaged when it is attached to or detached from the support mechanism. Moreover, since the rubber cover can be easily attached to and detached from the flange portion, cleaning of the flange portion and the cover can be improved.

Said plate consists of a microwave reflector.

A microwave reflector plate divides the heating chamber of the microwave oven into two spaces. Of these spaces, the space where the microwave source of the microwave oven is located is the space to be heated by microwaves (heating space), and the space where the microwave source is not located is the space to be heated by microwaves. It becomes a space (unheated space) that does not heat. Since microwaves are used for heating only in the heating space, the food can be efficiently heated.

Both the support mechanism and the mounting member are made of a microwave transparent material.

Since the microwaves pass through the support mechanism and the mounting member, both of which are made of a microwave transmitting material, and flow around to the upper side of the container, the food can be heated from the whole.

In the microwave cookware of the present invention, the heating of food in the microwave oven can be appropriately controlled according to the food.

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

(First embodiment)
1 to 4 show a microwave cooking utensil 10 (hereinafter simply referred to as cooking utensil 10) according to a first embodiment of the present invention and a microwave oven 1 in which the cooking utensil 10 is used.

Referring to FIGS. 1 to 4, the microwave oven 1 includes a microwave oven main body 2 having a heating chamber 3, which is a rectangular parallelepiped space with an opening on the front side in FIG. A closing door 4 is provided. Left and right side walls of the heating chamber 3 are provided with a pair of substantially linear guide rails (first support mechanism) 5 extending horizontally in the front-rear direction. A microwave oven main body 2 is provided with a magnetron 6 on the bottom wall of a heating chamber 3. - 特許庁

The cooking utensil 10 includes a plate 11 detachably supported in the heating chamber 3 and a container 21 detachably supported on the plate 11 .

5A and 5B, the plate 11 includes a rectangular plate body 12 in plan view and a dome-shaped portion 13 that bulges upward from the center of the plate body 12 in FIG. 5A. The plate 11 also includes a pair of generally linear suspension rails (second support mechanism) 14 provided on the lower surface of the plate body 12 in FIG. 5A with a gap in the width direction.

Each suspension rail 14 has a pedestal portion 14a joined to the plate 11, a hanging portion 14b extending downward from the pedestal portion 14a in FIG. and a support portion 14c. In this embodiment, the suspension rail 14 is made of a microwave transmitting material (for example, resin).

Referring to FIGS. 3 and 4, the container 21 includes a bottomed cylindrical container body 22 in which food is stored, and a mounting member 23 extending from the upper end of the container body 22 .

The container 21 in which the food is stored in the container body 22 is detachably supported by the suspension rails 14 by inserting both sides of the mounting member 23 into the suspension rails 14 of the plate 11 . Specifically, the mounting member 23 of the container 21 is supported by the suspension rail 14 by being placed on the support portion 14 c of the suspension rail 14 . When the container 21 is supported by the plate 11, the upper portion of the container body 22 and the dome-shaped portion 13 of the plate 11 face each other. The plate 11 and the container 21 supported by it are accommodated in the heating chamber 3 through the opening of the heating chamber 3 . The plate 11 is supported in the heating chamber 3 by placing both sides of the plate body 12 on the guide rails 5 .

In this embodiment, the entire plate 11 including the plate body 12 and the dome-shaped portion 13 is made of a microwave reflector. For example, by making the plate body 12 and the dome-shaped portion 13 metal, they can be used as microwave reflectors. Moreover, in this embodiment, the entire container 21 is made of a microwave transmitting material. For example, by making the container main body 22 made of glass or ceramic and the mounting member 23 made of resin, the entire container 21 can be a microwave transmitting body.

The height position of the guide rail 5 in the heating chamber 3, the shape of the plate 11, the length of the drooping portion 14b of the suspension rail 14, and the height of the container 21 are the same as the bottom surface of the heating chamber 3 and the bottom surface of the container body 22. It is set so that there is an interval between

When the food is heated by the micro-irradiation from the magnetron 6, a gap is provided between the bottom surface of the heating chamber 3 where the magnetron 6 is arranged and the bottom surface of the container body 22. can be avoided from being locally heated. In addition, even when using the same container 21, the design of the suspension rail 14, more specifically, the length of the hanging part 14b of the suspension rail 14 can be changed so that the bottom surface of the heating chamber 3 and the container body 22 are separated from each other. Since the distance from the bottom surface can be adjusted, the heating of the food by the microwave oven 1 can be appropriately controlled according to the food to be cooked. The distance between the bottom surface of the heating chamber 3 and the bottom surface of the container body 22 depends on the design of the guide rails 5 (for example, the installation height of the guide rails 5 in the heating chamber 3) and the design of the plate 11 (for example, the guide rails 5 to the bottom surface of the plate 11).

A heating chamber 3 of the microwave oven 1 is vertically divided into two spaces by a plate 11 which is a microwave reflector as a whole. Of these spaces, the space below where the magnetron 6 is located is a space to be heated by microwaves (heating space A), and the space above where the magnetron 6 is not located is a space not to be heated by microwaves. (Non-heating space B). Since the microwaves are used for heating only in the heating space A, the food to be cooked can be efficiently heated.

By preparing a plurality of plates 11 having different shapes, sizes, etc., and selecting and using one of them, appropriate heating according to the food to be cooked can be performed.

Since both the suspension rail 14 and the mounting member 23 are made of a microwave transmitting material, microwaves emitted from the magnetron 6 arranged on the bottom surface of the heating chamber 3 pass through the suspension rail 14 and the mounting member 23. It can wrap around to the upper side of the container 21 . Therefore, microwaves can be efficiently incident on the upper surface of the food to be cooked, and the upper surface of the food contained in the container main body 22 can be effectively heated. In other words, by making the suspension rail 14 and the mounting member 23 transparent to microwaves, the food can be heated from the whole.

Next, the container main body 22 and the mounting member 23 will be described more specifically.

First, referring to FIGS. 1 to 4, the bottom surface 3a of the heating chamber 3 extends in the front-rear direction (first direction) X and the width direction (second direction) Y. As shown in FIG.
