Description

microwave

The present invention relates to a microwave oven, and in particular, to prevent the inflow of electromagnetic material to the outside of the cooking chamber by preventing the inflow of metal materials such as wire into the cooking chamber through an exhaust pipe for discharging moisture or smoke in the cooking chamber. The present invention relates to a microwave oven that can be prevented.

A relatively large commercial microwave oven, as shown in Figure 1, the cavity 2 forming a rectangular cylindrical cooking chamber, the front plate 3 is coupled to the front surface of the cavity 2 and the front opening is formed, It has a main body including a back plate 5 which is coupled to the rear of the cavity 2 at a predetermined distance to form a component chamber, and the outer casing having a top plate and both side plates are coupled to the outside of the main body 1. do.

The component chamber formed at the rear of the cooking chamber generates high voltage transformer (HVT) for generating high voltage according to the supply of power, high voltage capacitor (HVC) for charging high voltage from the HVT, and electromagnetic waves in response to voltage supply from the HVC. And a magnetron to be supplied into the cooking chamber 2 are provided. Here, a pair of magnetrons are provided on both sides of the upper side of the rear wall of the cooking chamber, and a pair of waveguides for supplying electromagnetic waves from the magnetron into the cooking chamber is formed obliquely toward the upper center region of the cooking chamber on the upper surface of the cooking chamber. have.

In addition, as illustrated in FIG. 3, a discharge hole 11 for discharging steam and smoke from food during cooking is formed in the rear center region of the upper surface of the cooking chamber, and the discharge hole ( An exhaust pipe 15 extending from 11) to the back plate 5 is formed. In addition, an exhaust port 17 is formed at the distal end of the exhaust pipe 15 in the rear plate 5, and a blocking plate 20 for preventing foreign matter from flowing into the exhaust port 17 is formed on the rear of the exhaust port 17. It is attached inclined downward toward the outer side from the plate 5. In addition, the exhaust port 17 is provided with a guide guide 25 having an upper side and an opening facing the exhaust port 17 so as to guide water vapor and smoke from the exhaust pipe 15 to the upper part, and the lower part of the guide guide 25. The cotton is inclined upward so that water vapor and smoke are directed upwards.

The exhaust pipe 15 is almost blocked from the outside by the blocking plate 20 and the guide guide 25 attached to the exhaust port 17, as shown in Figure 2, the blocking plate 20 and the guide guide ( There is a gap for the release of steam and smoke. When a metal linear material such as the wire 40 is inserted into the gap, the wire 40 is bent along the upper surface of the cooking chamber and inserted into the exhaust pipe 15 to be introduced into the discharge hole 11 formed on the upper surface of the cooking chamber. do. Then, when the microwave oven operates, the electromagnetic wave is leaked to the outside of the microwave oven using the wire 40 as a medium, and harms the human body.

Accordingly, the plurality of blocking walls formed in the exhaust pipe 15 with the predetermined length in the transverse direction of the exhaust pipe 15 are provided so as to cross each other to prevent the insertion of the wire 40 from the outside. However, in the case of forming the barrier wall, since the barrier wall must be manufactured and attached separately in the exhaust pipe 15, a problem arises in that the cost is relatively high and the work process becomes cumbersome.

Accordingly, an object of the present invention is to provide a microwave oven that can easily prevent the wire 40 is inserted into the cooking chamber through the exhaust pipe.

The object of the present invention is a microwave oven having a cooking chamber in which discharge holes for discharging moisture and gas are formed, and an exhaust pipe installed in an area in which the discharge hole is formed to exhaust moisture or gas from the cooking chamber to the outside. It is achieved by a microwave oven, characterized in that it has a protruding jaw to prevent the introduction of a linear metallic object through the distal end of the exhaust pipe between the distal end toward the outside of the exhaust pipe and the discharge hole.

Here, the protruding jaw is preferably formed to protrude from the plate surface of the cooking chamber in the horizontal direction of the exhaust pipe.

Hereinafter, the present invention will be described in detail with reference to the drawings.

In the detailed description of the present invention, the same reference numerals are used for the same elements as in the prior art for the convenience of description.

As described with reference to FIG. 1, the microwave oven main body has a cavity 2 that forms a square-shaped cooking chamber with an open front and a rear open, and the cavity 2 has a predetermined upper surface extending further rearward. . The front plate (3) is formed in front of the cavity (2) is coupled to the front plate (3) is formed, the rear plate (5) in contact with the upper surface of the cavity 2 is coupled to the rear of the cavity (2), the back plate (5) The rear cover 4 is coupled to the front of the rear plate 5 to be spaced apart from the rear plate 5 to block the rear of the cooking chamber at the lower portion of the upper surface of the cavity 2. Here, a component compartment in which various control components are accommodated is formed between the rear plate 5 and the rear cover 4. On the other hand, the outside of the body is coupled to the outer casing (not shown) having a top plate and both side plates to form an appearance.

In the rear center area of the upper surface of the cooking chamber, as shown in Figure 2, the discharge hole 11 for discharging the steam and smoke generated from the food during cooking is formed, the discharge hole in the upper portion of the cooking chamber A rectangular cylindrical exhaust pipe 15 for discharging water vapor and the like from (11) to the outside extends to the rear plate 5. The rear plate 5 is formed with an exhaust port 17 for the passage of the exhaust pipe 15, the upper portion of the exhaust port 17 is a free end of the blocking plate 20 to prevent foreign matter from entering the exhaust port 17 As it goes down, it is attached obliquely downward. In addition, the exhaust port 17 is provided with a guide guide 25 having an upper side and an opening facing the exhaust port 17 so as to guide water vapor and smoke from the exhaust pipe 15 to the upper part, and the lower part of the guide guide 25. The cotton is inclined upward so that water vapor and smoke are directed upwards.

Meanwhile, a protruding jaw 30 protruding inwardly of the exhaust pipe 15 is formed at the rear of the lower surface of the exhaust pipe 15, that is, the region where the discharge hole 11 of the upper surface of the cooking chamber is formed. ) Is formed to extend in the transverse direction of the exhaust pipe (15). The protruding jaw 30 is formed within a predetermined range that can reach the upper surface of the cooking chamber when a metal material such as the wire 40 is inserted into the gap formed by the guide guide 25 and the blocking plate 20. Will be.

By such a configuration, when the wire 40 or the like flows into the exhaust pipe 15 into the gap formed by the guide guide 25 and the blocking plate 20, the wire 40 is formed on the lower surface of the exhaust pipe 15. The projecting jaw 30 is hit, and the elastic wire 40 is bent toward the upper surface of the exhaust pipe 15 by the projecting jaw (30).

Accordingly, the wire 40 may be prevented from being inserted into the discharge hole 11 formed in the upper portion of the cooking chamber along the exhaust pipe 15, and electromagnetic waves may flow out of the microwave oven through the inserted wire 40. Can be prevented. In addition, as in the prior art, instead of making a separate blocking wall in the exhaust pipe 15, it is only necessary to raise the upper surface of the cooking chamber to which the exhaust pipe 15 is attached so as to protrude by a predetermined length, thereby reducing the cost and working process. It's easy.

As described above, according to the present invention, it is possible to easily prevent the introduction of metallic linear objects such as wires into the cooking chamber through the exhaust pipe.
