1 to 7, the tray 1 for a microwave oven according to an embodiment of the present invention includes a container portion 10, a support portion 20, a fixing portion 30, and a roller portion 40. .

The container unit 10 is placed in a cooking chamber of a microwave oven and has a container shape in which food is placed. The container portion 10 may be directly put food or a container containing the food may be seated.

The support 20 is coupled to the container 10. The support 20 may be mounted in plural on the bottom of the container 10, and a support hole 23 is formed.

The fixing part 30 penetrates the support hole 23. The fixing part 30 is fixed to the support 20.

The roller portion 40 is rotatably coupled to the fixing portion 30. The roller portion 40 is rotated in contact with the cooking chamber of the microwave oven, so that the tray is rotated.

The coating layer 60 is formed on the outer surfaces of the container part 10, the support part 20, and the fixing part 30 by enameling. That is, in the state in which the support portion 20 is coupled to the container portion 10 and the fixing portion 30 is fixed to the support portion 20, enameling is performed on the support portion 20 to form the coating layer 60 on the outer surface. do.

Microwave tray 1 according to an embodiment of the present invention is further provided with a washer portion (50). The washer part 50 is fitted to the fixing part 30 to support the roller part 40.

Support portion 20 according to an embodiment of the present invention is provided with a coupling plate 21 and the support plate 22. The coupling plate 21 is coupled to the bottom of the container portion 10 by welding or bolting. The support plate 22 is bent and extended from the coupling plate 21, and a support hole 23 is formed.

The fixing part 30 according to the exemplary embodiment of the present invention includes a through body 31, a locking body 32, and a deformable body 33.

The penetrating member 31 has a tubular shape and penetrates the support hole 23. The locking body 32 is provided at one end of the through body 31 and has a larger diameter than the support hole 23. The deformable body 33 is provided at the other end of the through body 31. The deformable body 33 has the same diameter as the through body 31 and is bent laterally by an external force to have a length longer than the diameter of the support hole 23.

The locking body 32 has a cut spherical shape having an outer circumferential surface thereof. That is, one end of the locking body 32 is formed with a spherical surface, the other end forms a partition wall vertically. The locking body 32 is increased in diameter from one end to the other end in cross-sectional area.

The deformable body 33 is bent laterally by a deformable tool such as a punch and locked to the support plate 22.

On the other hand, the roller portion 40 is formed in the roller hole 41 corresponding to the maximum diameter of the locking body 32 to pass through the locking body (32). The washer part 50 is formed with a washer hole 51 smaller than the maximum diameter of the locking body 32.

The washer part 50 is made of elastic soft material. When the washer part 50 comes into contact with the locking body 32 while passing through the locking body 32, the washer hole 51 expands to correspond to the diameter of the locking body 32 and passes through the locking body 32. .

When the washer part 50 passes through the locking body 32, the diameter of the washer hole 51 is reduced, and the washer part 50 is locked to the locking body 32.

Referring to FIG. 8, a method for manufacturing a tray for a microwave oven according to an embodiment of the present invention having the above configuration is as follows.

Couple the plurality of support portions 20 to the ground of the container portion 10 is placed food (S10) (see Fig. 2). The support part 20 is provided with a coupling plate 21 coupled to the bottom of the container part 10 and a support plate 22 which is bent from the coupling plate 21 to extend and a support hole 23 is formed.

In the state in which the container portion 10 and the support portion 20 are coupled, the fixing portion 30 is fixed to the support portion 20 (S20).

The fixing part 30 includes a penetrating member 31 penetrating the support hole 23, a locking member 32 formed at one end of the penetrating member 31, and a curved surface, and the other end of the penetrating member 31. A deformable body 33 is formed which is formed and bent laterally by an external force.

Therefore, when the deformable body 33 to which no external force is applied passes through the support hole 23, the through body 31 passes through the support hole 23, and the locking body 32 is caught by the support plate 22 (FIG. 3). Reference).

In the above state, when the deformation tool is inserted into the tubular deformable body 33 and an external force is applied, the deformable body 33 is bent laterally and caught by the support plate 22, so that the fixing part 30 is supported by the support part 20. To remain locked (see Figure 4).

In the state in which the fixing part 30 is fixed to the support part 20, the roller part 40 is fitted to the fixing part 30 (S30) (see FIG. 6).

The roller portion 40 is formed with a roller hole 41 corresponding to the maximum diameter of the locking body 32, the roller portion 40 is located in the through body 31 after passing through the locking body (32). When the roller portion 40 is seated in the cooking chamber of the microwave oven and rotated, the container portion 10 is rotated.

On the other hand, after the step (S20) of fixing the fixing portion 30 to the support portion 20, the metal container portion 10, the support portion 20, and the outer surface of the fixing portion 30 through the enamel operation The coating layer 60 is formed (S40) (see FIG. 5).

That is, the fixing part 30 is enameled in a state where the fixing part 30 is locked to the support part 20, and after the container part 10 and the support part 20 are enameled, the fixing part 30 is attached to the support part 20. Damage to the coating layer 60 generated in the process of bonding can be prevented.

After the roller unit 40 is coupled to the fixing unit 30 (S30), the washer unit 50 is fitted to the fixing unit 30 (S50) (see FIG. 7).

Since the washer part 50 is made of soft material having elasticity, when the washer part 50 is contracted after passing through the catching body 32 of the fixing part 30, the washer part 50 is fixed to the catching body 32 and the roller is fixed. The separation of the part 40 is prevented.

Although the present invention has been described with reference to the embodiments shown in the drawings, this is merely exemplary, and those skilled in the art to which the art belongs can make various modifications and other equivalent embodiments therefrom. I will understand.

Therefore, the true technical protection scope of the present invention will be defined by the claims below.
