Description

Microwave Speaker Mounting Structure

The present invention relates to a microwave oven, and more particularly, to a speaker mounting structure of a microwave oven for minimizing interference between components due to spatial constraints by mounting a speaker on the bottom plate of the microwave oven.

In general, a microwave oven is a device that cooks food by uniformly heating food using a high frequency (microwave) generated from the magnetron, it is possible to perform a variety of cooking, such as cooking food, as well as cooking the food. .

As shown in FIG. 1, the microwave oven has a cabinet 11 for cooking, and a high frequency radiated from the magnetron 12 is provided at one side of the cabinet 11. A waveguide 13 is formed to guide the inside of the cabinet 11. A tray 15, which is rotated according to the driving of the motor 14, is seated below the cabinet 11, and the cabinet 11 is provided. In the upper side of the inside is mounted a heater 16 for generating heat.

Therefore, when the cooking condition is selected while the food F is seated on the tray 15 and the microwave oven is operated, the high frequency oscillated by the magnetron 12 is radiated into the cabinet 11 through the waveguide 13. At the same time, as the tray 15 rotates according to the driving of the motor 14, the high frequency introduced into the cabinet 11 through the waveguide 13 is uniformly transmitted to the food F so that the food is cooked uniformly.

In the related art, when the microwave oven has a voice instruction function for explanation or guidance, the speaker 21 is mounted inside the operation panel 20 as illustrated in FIG. 2.

However, according to the conventional speaker mounting structure of the microwave oven, as it is attached toward the front side of the main body 10, it is difficult to assemble due to interference between components due to spatial constraints, thereby lowering the productivity of the product, thereby increasing the manufacturing cost Several problems were inherent, such as acting as factors.

Accordingly, an object of the present invention is to solve the above problems of the conventional speaker mounting structure of a microwave oven, and to provide spatial constraints by mounting a speaker for outputting voice information on a bottom plate. Minimizes the interference between components due to this, and easy to assemble, improve productivity and reduce the manufacturing cost of the microwave speaker mounting structure to provide.

Speaker mounting structure of the microwave oven according to the present invention for achieving the above object, the cabinet; A bottom plate coupled to the lower side of the cabinet and having a plurality of holes formed therein; A horn member detachably coupled to the bottom plate on which the plurality of holes are formed; And a speaker coupled to an upper side of the horn member.

Here, the horn member includes a plurality of lower hooks inserted into and fixed in coupling holes formed in the bottom plate, and a plurality of upper hooks to which the speaker is coupled.

According to the present invention, the horn member is mounted on the bottom plate, the speaker is mounted on the horn member to minimize the interference between components due to spatial constraints during assembly, thereby facilitating assembly and further improve the productivity The cost is significantly reduced.

Hereinafter, preferred embodiments of the present invention will be described in more detail with reference to the accompanying drawings.

Figure 3 is an exploded perspective view showing a speaker mounting structure of the microwave oven according to the present invention, Figure 4 is a cross-sectional view of the combination of the present invention, the bottom plate 30 is formed with a plurality of through holes 31, the edge is coupled to The hole 32 is formed.

The horn member 40 is detachably coupled to the coupling hole 32, and the speaker 50 is coupled to the upper side of the horn member 40.

The horn member 40 spreads the sound waves radiated from the speaker 50 and propagates to the outside of the main body through the through hole 31, and a plurality of lower hooks 41 are inserted into and fixed in the coupling hole 32 at the lower end thereof. ) Is protruded, and a plurality of upper hooks 42 protruding from the flange 51 of the speaker 50 are protruded from the upper side thereof.

In addition, the horn member 40 is preferably formed to gradually increase in diameter from the upper side to the lower side so as to diffuse the sound waves emitted from the speaker 50.

Hereinafter, the operation of the speaker mounting structure of the microwave oven according to the present invention will be described in detail.

The lower hook 41 of the horn member 40 is inserted into and fixed to the coupling hole 32 of the bottom plate 30 coupled to the lower side of the cabinet, and the flange portion of the speaker 50 is attached to the upper hook 42 on the upper side thereof. By inserting and fixing 51, the operation of assembling the speaker 50 to the bottom plate 30 is completed.

In this case, when using a microwave oven, when selecting a guide, etc., sound waves are emitted from the speaker 50, and the sound waves are diffused through the horn member 40, and then a plurality of through holes formed in the bottom plate 30 ( 31) to the outside.

In addition, the sound wave radiated from the speaker 50 is diffused from the horn member 40 and then radiated to the outside to increase the intensity of the sound wave.

Therefore, since the speaker 50 that emits the voice is fixed to the bottom plate 30 fixed to the cabinet, the assembly of the speaker 50 can be minimized because the interference between components due to spatial constraints can be minimized when the speaker 50 is assembled. It is possible to facilitate, thereby improving the productivity of the product, it is possible to reduce the manufacturing cost.

As described above, according to the present invention, the horn member is mounted on the bottom plate, and the speaker is mounted on the horn member, thereby minimizing interference between components due to spatial constraints during assembly, thereby facilitating assembly and further improving productivity. And the manufacturing cost is significantly reduced, such as a number of effects.

Although specific embodiments of the present invention have been illustrated and described above, the present invention is not limited to the above-described embodiments, and the technology to which the present invention pertains without departing from the gist of the present invention as claimed in the claims. Various modifications can be made by those skilled in the art, and such changes are within the scope of the claims.
