Description

[Detailed explanation of the invention] This invention relates to the improvement of microwave ovens.
In particular, it relates to a microwave oven with a vertically swinging door held by two arms.

This invention will be explained below with reference to an embodiment shown in the drawings. 1 is a main body of a microwave oven, 2 is a heating chamber, and 3 is a door that closes the front opening of this heating chamber, and the lower edge is connected to the main body 1 by a hinge (not shown). Supported.

4 is a handle, 5 and 6 are arms whose one end is rotatably supported by pins 7 provided at both left and right ends of the door 3, and the other end is inserted into the main body 1 and is supported by a roller 8.
is maintained. Reference numeral 9 denotes a hook portion formed at the tip of the arms 5 and 6, which is blocked by the roller 8 when the door 3 is opened, thereby preventing the door 3 from being opened excessively.

10 is a tension spring that always urges the arms 5 and 6 inward to the main body 1, 11 and 12 are pins protruding from the closing surface of the door 3 and near the base of the arms 5 and 6, and 13 and 14 are tension springs. When the door 3 is closed, the pin 1
Small holes 15 and 15 are formed on the front surface of the main body 1 so that the small holes 1 and 12 are inserted, and the safety switch is placed behind this small hole and is inserted into the power supply circuit of a magnetron (not shown). 16 and 17 are heaters,
18 is a timer knob, and 19 is a cooking start button.

With the above configuration, when the door 3 is opened now, the safety switch 15 is no longer pressed by the pins 11 and 12, so it opens, and therefore the oscillation of radio waves stops.

When the door 3 is closed, the pins 11 and 12 close the safety switch 15, making it possible to oscillate radio waves, and when the cooking start button 19 is pressed, the radio waves are oscillated.

As explained above, since the pins 11 and 12 are provided near the arms 5 and 6, when the door 3 is opened, the upper surface of the door 3 can be used widely, and the pin 1
The small holes 13 and 14 for insertion of the heating chambers 1 and 12 are provided at low positions, so that even when hot air etc. in the heating chamber 2 is released, there is little intrusion and the safety switch 15 is not overheated.

In the above embodiment, the pins 11 and 12 were mere protrusions, but it goes without saying that they may be of a latch type, in which they are moved by operating the handle 4 of the door 3. In addition, as shown by the imaginary lines in Fig. 2, if the arms 5 and 6 are installed rearward, the door 3
The closing surface can be used widely.

As described above, according to this invention, when the door is opened, the upper surface can be used widely, making it convenient for putting in and taking out hot dishes, etc., and placing them there.In addition, the temperature around the safety switch can be kept low, resulting in stable operation. This has the effect of increasing the lifespan.

[Brief explanation of the drawing]

FIG. 1 is a front view of an embodiment of this invention when the door is open, and FIG. 2 is a side view of the main parts thereof. In the figure, 1 is the main body, 3 is the door, 5 and 6 are arms,
11 and 12 are pins, and 15 is a safety switch.

Claims (1)

[Scope of Claim for Utility Model Registration] (1) In a door equipped with a door whose lower edge is rotatably supported on the front of the main body, arms are provided at the left and right ends of the door, and the tips of the arms are The microwave oven is hooked and held on the main body and has a pin for opening/closing a safety switch provided inside the main body on the door closing surface near the arm. (2) The microwave oven according to claim 1 of the utility model registration, characterized in that a pair of pins are provided, and these are provided near the left and right arms, respectively.
