The electric compartment 80 is partitioned.

Therefore, when the microwave oven is operated in a state in which the cooked material or the container containing the cooked material is accommodated inside the cooking chamber 30, the microwaves oscillated from the magnetron accommodated in the electric field chamber 80 may move the waveguide 50. It is introduced into the inside of the cooking chamber 30, and the cooked matter is cooked by the microwave introduced as such.

However, in the above-described general monitor look type microwave oven, there is no big problem in domestic water due to the structure in which a noise filter for attenuating noise generated in the process of amplifying microwaves is not provided. There was a problem of lowering the reliability of the product.

In addition, the structure in which the noise filter is not provided as described above has a problem that the product cannot be exported because it is contrary to international standards.

Accordingly, a technical problem to be achieved by the present invention, that is, an object of the present invention is to solve the problem of the conventional monitor look type microwave, and effectively attenuates noise generated when the monitor look type microwave is operated. The present invention provides a monitor look type microwave oven that improves the reliability of the product.

Another object of the present invention is to provide a monitor look type microwave oven that facilitates the export of products by attenuating noise generated during operation of the monitor look type microwave oven.

In order to achieve the above object, the present invention, a case in which the inner body is formed by the case, the front panel and the rear panel is mounted on the front; A cooking compartment formed above the case and opened and closed by a door; An electric compartment having a compartment formed below the case and having an electric component such as a magnetron and a high voltage transformer and a fan motor for air-cooling heat generated from the components; And a monitor look type microwave oven provided inside the electric chamber and including noise attenuation means for attenuating noise generated when the electrical components are operated.

Hereinafter, with reference to the accompanying drawings, preferred embodiments of the present invention for achieving this purpose will be described in detail.

1 is a front view showing an embodiment of a general monitor look type microwave oven to which the present invention is applied, and FIG. 3 is a side view showing a state where the present invention is installed, and the same reference numerals are assigned to the same parts and members as in the prior art.

In other words, the noise attenuation means according to the present invention will be described with reference numeral "90".

As illustrated, the microwave oven main body 10 of the monitor look type to which the present invention is applied has a housing shape, and an upper side thereof includes a cooking chamber 30 opened and closed by a door 20 and a lower side according to a function. The control panel 40 for moving is mounted and the external shape is formed.

That is, the main body 10 is formed by the case 11 made of a metal material as shown in FIG. 3, and the front panel 12 and the rear panel 13 are mounted before and behind the main body 10.

On the other hand, inside the cooking chamber 30, a magnetron (not shown) in which high frequency oscillates and a waveguide 50 for guiding the microwaves oscillated by the magnetron into the cooking chamber 30 are provided in the case 11. Parts such as a high-voltage transformer 60 and a high-pressure capacitor (not shown) mounted on one side and applying a high voltage to the magnetron, and a fan motor 70 cooling the heat generated from each of these electrical components are accommodated. The electric room 80 is partitioned, and these configurations are the same as those of the general monitor look type microwave oven described above.

However, a feature of the present invention is that the inside of the electric chamber 80 is provided with a noise attenuation means 90 for attenuating the noise generated when the electrical components are driven by the operation of the microwave oven.

Preferably, the noise attenuation means 90 is preferably disposed in the vicinity of the noise attenuation means 90 so as to be cooled by the blowing force generated when the fan motor 70 is driven.

The noise attenuation means 90 is a plate-like support member 91 coupled to the one side wall of the case 11 exposed to the inside of the electric chamber 80 by the coupling member 94 and the support member ( It is provided with a plurality of support protrusions 92 having a locking projection 93 integrally protruded on the edge side of the 91 and the noise filter 95 sandwiched between the locking projections 93.
