Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a turntable for a microwave oven on which food to be cooked is placed and driven to rotate in an oven chamber.

[Conventional technology]

In the microwave oven, as shown in Figure 4,
A turntable 2 for placing food on the oven is arranged in the oven chamber 1, and the food on the turntable 2 is heated uniformly by rotating the turntable 2 during heating. Common.

FIG. 5 is a longitudinal cross-sectional view showing a conventional support configuration of the turntable 2 in the oven interior 1, in which the rotation of the motor 5 is transmitted to the bottom of the oven interior 1 via the shaft 3 and the coupling ring 4. A roller rotation shaft 6 is disposed, and as the roller rotation shaft 6 rotates, rollers 7, 7 pivotally supported at both ends thereof roll on the bottom surface of the oven interior 1, and accordingly, the rollers 7, 7 rotate. A turntable 2 placed thereon is configured to rotate.

Incidentally, an inclined wall surface extending upwardly is provided around the periphery of the food placing surface on the front side of the turntable 2 in order to prevent the food from falling.

It is well known that the configuration in which the turntable 2 on which the food is placed is rotated during cooking is extremely effective in uniformly heating the food.

[The problem that the idea attempts to solve]

However, in the above configuration, there is a problem in that it is not possible to heat a large or large amount of food that protrudes from the turntable 2, and this restricts the shape of the food. That is, although the oven interior 1 normally has a rectangular planar cross-sectional shape, its four corners are dead spaces in which food cannot be placed. This is because if a food with a shape that protrudes from the turntable 2 into these areas is placed on the turntable 2, as the turntable 2 rotates, the food will be placed on the side wall of the oven interior 1. This is because things become usable. As described above, conventionally, the space inside the oven chamber 1 cannot be fully utilized.

This invention was made in view of the above, and
The purpose is to make it easier to switch from a rotary heating support state that involves rotation to a support state that allows food to be placed over almost the entire area inside the oven, in response to user requests. It is an object of the present invention to provide a turntable for a microwave oven that can be provided with a structure.

[Means to solve the problem]

Therefore, the turntable for a microwave oven of the present invention has a planar surface that is almost the same as the food placement surface on the front side, on the center side of the back side where the outer peripheral edge side is supported by the rollers rolling on the bottom surface of the refrigerator. is provided with a cooking food placement surface portion on the back side thereof, and a side wall portion having a protruding portion having a height dimension larger than the diameter of the roller is provided on the front surface at a position radially outer than the roller. It is characterized by

[Effect]

According to the above configuration, by placing the turntable on the roller with the food placement surface on the front side facing upward, the turntable is caused to rotate as the roller rolls. On the other hand, when the above-mentioned turntable is placed face down on the bottom of the refrigerator, a side wall portion having a protrusion larger in height than the diameter of the roller is provided at a position radially outward from the roller. Because of this, the end surface of this side wall portion comes into contact with the bottom surface of the inside of the refrigerator, and therefore, this turntable is positioned at a distance from the rollers. As a result, this turntable is held in a stationary state, so even if a food with a shape that protrudes from this turntable is placed on this turntable, if it is rotated, it will not be able to enter the refrigerator. It can be heated without causing the conventional problem of hitting the wall. In this way, in the above, with one turntable, by the simple operation of turning it over,
It is possible to switch between a rotating heating state that involves rotation and a stationary heating state that allows food to be placed over almost the entire area inside the oven, and it is possible to switch between Since the above switching can be performed without installing a turntable with a different shape or changing the specifications of the microwave oven itself, the overall configuration can be made simpler. can.

[Embodiment] An embodiment of the present invention will be described below with reference to FIGS. 1 to 3.

FIG. 1 is a longitudinal cross-sectional view of the main part of the bottom of the oven interior of a microwave oven having a structure similar to that shown in FIG. A roller 9 that rolls on the bottom surface is attached, and a turntable 20 is supported by the roller 9 on the back side thereof. In the turntable 20, each central side of both the front side and the back side is formed as planar food placement surfaces 20a and 20b, respectively. And these cooking food mounting surface parts 20a, 20
On the back surface on the radially outer side of b, a supported surface portion 22b, which is recessed slightly upwardly than the back food placement surface portion 20b, is formed as a receiving surface for the roller 9. This supported surface portion 22b
A side wall portion 23 that protrudes vertically from both the front and back surfaces is provided on the outer peripheral edge of the side wall portion 23.
The protruding length of the roller 3b is set smaller than the diameter of the roller 9. Therefore, when this turntable 2 is placed on the roller 9 as shown in the figure, the upper part of the peripheral surface of the roller 9 is connected to the supported surface part 2.
2b from below, and as a result, when the roller rotation shaft 8 is rotationally driven and the roller 9 rolls on the bottom of the chamber, the turntable 2 also rotates as the roller 9 rolls. , a rotational movement concentric with the center of rotation of the roller rotation shaft 8 is produced.

The surface side protruding portion (protruding portion) 23 a extending upward in the side wall portion 23 has a protruding length L larger than the diameter of the roller 9 . Therefore, when the turntable 20 is turned over from the state shown in FIG. 1 and placed on the bottom surface of the oven interior 14, as shown in FIG.
The turntable 20 is released from the rollers 9 and directly supported on the bottom surface of the oven interior 14, and is in a state where it is lifted from the rollers 9, that is, a state where it is not driven by the rollers 9. Therefore, the turntable 20 is in a stationary state. It will be held.

In this way, by setting the turntable 9 in a non-rotatable supported state where it is completely raised from the roller 9, even large or large quantities of food that protrude from the turntable 20 can be accommodated in the oven chamber 14. The four corners of the oven interior 14 (indicated by diagonal lines) cannot be used because the food gets stuck when cooking by rotating the turntable 20 as shown in the plan view in Fig. 3. (shown) can also be used effectively. Further, the turntable driving motor is not overloaded as a result of this.

[Effect of idea]

As described above, the turntable for a microwave oven of the present invention has a surface portion on the center side of the back side, the outer peripheral edge of which is supported by the rollers rolling on the bottom surface of the refrigerator, which is almost the same as the food placement surface on the front side. is provided with a planar back side food placement surface portion, and the front surface is provided with a side wall portion having a protruding portion having a height larger than the diameter of the roller at a position radially outward from the roller. This is the configuration that is used.

As a result, by simply flipping the turntable over, a single turntable can be used to provide rotational heating support with rotation, and stationary heating support that allows food to be placed over almost the entire area inside the oven. It is possible to switch between states. Therefore, compared to, for example, providing separate turntables corresponding to each of the above-mentioned support states or changing the specifications of the microwave oven main body, the present invention can be more simply configured.
