Description

[Detailed description of the invention] [Industrial field of application] The present invention is based on a rotating table provided in a cooking chamber for the purpose of preventing uneven heating of the food to be cooked, such as in a microwave oven. In order to facilitate cleaning or to enable cooking on a grill instead of the rotary table, the table side fitting part formed on the underside of the rotary table is installed at the bottom of the cooking chamber. This invention relates to a cooking machine equipped with a position-determining fitting mechanism that is removably fitted from above and below to a drive-side fitting portion formed on a drive rotating member, and the position is fixed by this fitting. .

[Conventional technology]

In the cooking machine mentioned above, as shown in Fig. 6,
The table side fitting part 08 formed on the lower surface of the rotary table 03 is formed on the drive rotating member 04, which is provided in a posture to protrude upward from the inner bottom plate 01a at the cooking cabinet position, which is formed substantially flush with the table side fitting part 08. A position fixing fitting mechanism A that can be detachably attached to the side fitting portion 04a from above and below to fix the rotary table 03 to the normal attachment position with respect to the driving rotation member 04 is provided. It was prepared.

[The problem that the idea attempts to solve]

For this reason, when attaching the rotary table to the drive rotating member, the rotary table must be moved horizontally over a wide range within the cooking cabinet, and the table-side fitting portion and the drive-side fitting portion must be moved horizontally within the cooking cabinet. It is necessary to put it on while estimating the relative position, which has the disadvantage that it cannot be put on smoothly.

The present invention has been developed in view of the above-mentioned circumstances, and is devised so that the relative position of the rotary table to the driving rotating member can be easily specified within a certain range, so that the rotating table can be easily positioned relative to the driving rotating member. The purpose is to make it easy to install.

[Means to solve the problem]

The characteristic structure of this invention to achieve the above purpose is as follows:
In the cooking machine mentioned above, a recessed surface portion surrounding either the drive-side fitting portion or the table-side fitting portion is provided, and the fitting start position of both the fitting portions is set. is set to enter within the range of the recessed space of the recessed surface part, and both fitting parts enter into the range of this recessed space and are temporarily positioned, and in this provisional positioning state, the rotary table is held horizontally. The position of both fitting portions is determined within the range of directional movement, and this configuration provides the following effects.

[Effect]

The recessed surface surrounds one of the mating parts, and the mating start positions of the two mating parts are set to enter the range of the recessed space of the recessed surface. The mating portion can be temporarily positioned at a position close to the regular mating position by entering the recessed space with a wide opening surrounding the regular mating position.

Then, since both mating parts are positioned in the horizontal movement range in the temporary positioning state where the other mating part is in the recessed space, the normal mating position can be reached without canceling the temporary positioning state. Can be attached to.

[Effect of idea]

Therefore, when attaching the rotary table to the drive rotating member, the other fitting part is inserted into the recess space of the recessed surface part surrounding one fitting part in advance, and the other fitting part is inserted into the recessed space of the recessed surface part surrounding the other fitting part. Since it is easy to maintain the fitting part near the drive-side fitting part, the relative position of the fitting parts within the range in which the fitting part inserted into this recessed space can be moved in the horizontal direction. It can be installed simply by guessing, whereas conventional methods require estimating the relative positions of the mating parts while moving the rotary table horizontally over a wide range within the cooking cabinet. It can be installed more easily than the .

In the cooking machine according to claim 2, since the recessed surface portion surrounding the drive side fitting portion is formed on the inner bottom plate of the cooking chamber, the lower surface of the rotary table can be easily formed into a flat surface that is easy to clean. In addition, the table side fitting part can be easily moved into the recessed surface part by horizontally moving it along the bottom plate inside the cooking cabinet.

In the cooking machine according to claim 3, since the recessed surface portion surrounding the drive-side fitting portion is formed on the drive rotation member, the bottom surface of the rotary table and the top surface of the bottom plate inside the cooking cabinet can be easily cleaned. Easy to form into a flat surface.
