Description

[Detailed explanation of the idea] (b) Industrial application fields The present invention relates to a cooking device such as a microwave oven.

(b) Prior Art In a cooking device such as a microwave oven, a cooking chamber formed in the main body is closed off with a door that can be opened and closed. This door is usually provided with a door latch as shown in Japanese Utility Model Publication No. 53-53955, but the conventional door latch protruded from the rear surface of the door toward the main body as shown in the same publication. Therefore, in such a conventional structure,
When opening the door to take food in and out of the cooking chamber, the door latch can get caught on the food or on the hands or clothes of the person using the cooker, making it inconvenient to use.

(c) Problems to be Solved by the Invention The object of the invention is to provide an easy-to-use cooker in which the door latch does not protrude significantly from the rear surface of the door and therefore does not get caught on the user's clothes. It is something to do.

(d) Means for Solving the Problems The cooking appliance of the present invention comprises a cooking chamber formed in a main body, a door provided in the main body for opening and closing the cooking chamber, and a protrusion on the front side of the peripheral edge of the door. A door latch that protrudes from the rear side of the protruding edge and is located substantially within the thickness of the door, and a latch engaging portion that protrudes forward from the front plate of the main body. shall be.

(E) Function Since the door latch is located almost within the thickness of the door, it does not protrude significantly from the rear surface of the door.

(f) Embodiment FIGS. 1 to 3 show a microwave oven which is an embodiment of the present invention.

1 is the main body of the microwave oven, 2 is a cooking chamber formed in the main body 1 by the oven frame 2b, and 3 is an electrical equipment room formed on the side of the cooking room 2 in the main body 1; A large number of electrical components (not shown), such as a magnetron that supplies high frequency waves and its drive circuit, are housed inside. Reference numeral 4 denotes a front plate provided at the front of the main body 1 and forming an opening 2a of the cooking chamber 2. A control frame 7 having a keyboard 5 and a display 6 is attached to the front of the front plate 4 in a portion corresponding to the electrical equipment compartment 3. ing. A door 8 is rotatably provided in the main body 1 on the opposite side of the control frame 7 across the opening 2a, and opens and closes the cooking chamber 2.

9 is a metal door body, 10 is a metal shield plate that forms the rear surface of the door 8, and 11 is a chiyoke groove formed by these two members. When the door 8 is closed, the shield plate 10 is a front plate around the opening 2a. 4 to prevent high frequency leakage. 12 is a chiyoke dielectric that covers the chiyoke groove 11, and 13 is a door body 9.
This is a door cover that covers the front side of the door 8 and forms the front side of the door 8.

Reference numeral 14 designates a protruding edge portion of the peripheral edge of the door 8 that protrudes from the front side of the side edge on the control frame 7 side;
It is constructed by modifying the ends of the yoke dielectric 12 and the door cover 13. Reference numeral 15 designates a door latch which is rotatably supported on the projecting edge 14 by a shaft 16 and projects from the rear side of the projecting edge through a latch hole 17. The size of this door latch 15 is such that its tip 15a is approximately aligned with the rear surface of the door 8, or is located on the front side thereof,
The door latch 15 is located approximately within the thickness of the door 8 (indicated by A in the figure).

Reference numeral 18 denotes a latch engaging portion protruding forward from the front plate 4 of the main body 1, and is formed integrally with the control frame 7 on the side thereof. The latch engagement portion 18 includes a latch insertion hole 19 into which the door latch 15 is inserted when the door 8 is closed, and a lock portion 20 into which the inserted door latch 15 is locked.
The locked door latch 15 turns on the magnetron so that it can oscillate, and the door 8
A door switch 21 is provided which turns off when opened and stops the oscillation of the magnetron to prevent high frequency leakage.

According to the present invention, since the door latch 15 is located almost within the thickness of the door 8, compared to the conventional structure in which the tip 15a of the door latch 15 protrudes significantly from the rear surface of the door 8, the door latch 15
There is almost no risk that food or the user's hand may get caught in the cooking device 5, making it possible to obtain an easy-to-use cooking device.

Furthermore, in this embodiment, the door switch 21 and the lock part 20, which occupied a considerable space in the electrical equipment compartment 3 in the conventional configuration, are provided in the latch engaging part 18 that protrudes forward from the front plate 4. can be used more widely.

Furthermore, in this embodiment, the latch engaging part 18 and the control frame 7 are integrated to reduce the number of parts and cost. It is also possible to configure the frame 7 separately.

(g) Effects of the invention According to the invention, the door latch does not protrude significantly from the rear surface of the door, and therefore the door latch does not get caught on the food being taken out or put in or the user's clothes, making cooking easier to use. A vessel is obtained.
