Description

Mounting Structure of High Voltage Transformer for Ventillation Hooded Microwave Oven}

The present invention relates to a microwave oven, and more particularly to a hood-mounted microwave transformer mounting structure for mounting the transformer of the hood-mounted microwave electronic chamber on the back plate.

In general, the hood-only microwave oven has an exhaust function for exhausting heat and smoke generated in the gas oven range in addition to the cooking function which is a function of the microwave oven.

Hooded microwave ovens tend to be increasingly used due to the efficiency of space utilization of gas ovens and microwave ovens and the comfort of the environment.

Microwaves are commonly used as a heating source for cooking food in a microwave oven. The microwave is radiated by the oscillation of the magnetron, and the magnetron generally requires a high voltage of 4000V or more in order to oscillate the microwave.

By the way, the voltage applied to the home is a relatively very low voltage of usually 100V ~ 250V. Therefore, in order to cook using microwave at home, a high voltage transformer for boosting the household voltage above 4000V is required.

Therefore, in the microwave oven using a microwave, the magnetron and the high voltage transformer are incorporated together.

Next, based on the accompanying drawings, Fig. 1 and Fig. 2, a full-length transformer mounting structure of a conventional microwave oven (hereinafter, simply referred to as a "microwave oven") according to the prior art will be described.

As shown in FIG. 1, the hood-use microwave oven 1 is provided with a cavity 2, which is a space for cooking food by heating food. The electric field chamber 4 is installed in the side surface of the cavity 2. The electric chamber 4 has a plurality of parts for supplying microwaves, which are heating sources for heating food. The space of the cavity 2 and the electric compartment 4 is partitioned by the cavity side wall 2a.

As the components incorporated in the electric compartment 4, first, a magnetron 18 for oscillating a microwave which is a heating source for heating food is mounted on the cavity side wall 2a and installed in the electric compartment 4. In addition, a high voltage transformer 20 for boosting the voltage applied to the magnetron 18 to a high pressure is provided in the bar plate 8 forming the bottom surface of the electric chamber 4.

The bar plate 8 is coupled to the front plate 12 forming the front of the microwave oven and the back plate 10 forming the rear surface of the microwave oven. The front plate 12 and the back plate 10 are coupled to the base plate 6 forming the bottom surface of the microwave oven 1.

In addition, the air guide 16 is installed in the bar plate 8 in parallel with the back plate 10. The air guide 16 forms the rear surface of the electric compartment 4, and at the same time between the back plate 10 and the exhaust gas exhausted from the gas oven range (not shown) below the microwave oven 1 is a cavity ( 2) It serves to guide the exhaust to the exhaust motor (not shown) installed on the top.

The front surface of the electric compartment 4 is formed by the control unit 14. The control unit 14 is provided with various function buttons for the operation and function of the microwave oven.

Next will be described the operation of the transformer mounting structure according to the prior art having the configuration as described above.

The transformer 20 is installed on one side of the bar plate 8. The mass of the said transformer 20 is 5 kg or more, and has a big load. Accordingly, since the bar plate 8 may be deformed due to the load of the transformer 20, the bar plate 8 may have the front plate 12 and the back plate 10 to prevent the bar plate 8 from being deformed. Are combined. In addition, since the bar plate 8 is connected to the air guide 16, the strength is further reinforced.

In addition, the bar plate 8 forming the bottom surface of the electric compartment 4 and the air guide 16 forming the rear surface of the exhaust chamber exhausted from the gas oven range (not shown) installed below the microwave oven 1. (2) It serves to guide the exhaust motor (not shown) installed in the upper portion.

That is, the exhaust gas exhausted from the gas oven range (not shown) is sucked into the suction port (not shown) provided in the base plate 6 of the microwave oven 1 so that the bar plate 8 and the base plate 6 Through the space to be formed, the air guide 16 and the back plate 10 pass through the ducts are formed and is sucked into the exhaust motor (not shown).

However, the microwave oven mounting structure according to the prior art having the configuration and operation as described above causes the following problems.

According to the prior art, a separate bar plate 8 for supporting the transformer 20 is provided. In addition, the load of the transformer 20 is very large, causing the deformation of the bar plate 8 to sag downward.

Therefore, in order to prevent the bar plate 8 from sagging downward, the bar plate 8 is connected to the front plate 12 and the back plate 10. Further, by connecting the air guide 16 to the bar plate 8, the bar plate 8 is more reliably prevented from sagging down.

In other words, the mounting structure of the transformer 20 according to the related art requires a separate member such as the air guide 16 to mount the transformer 20, resulting in an increase in the product cost and an increase in the number of parts. It causes a decrease in productivity.

In addition, the exhaust gas exhausted from the gas oven range is outside the microwave oven 1 through a space between the bar plate 8 and the base plate 6 and a space between the air guide 16 and the back plate 10. Is exhausted.

In other words, the exhaust gas of the gas oven range is introduced from the lower portion of the microwave oven 1 and is not directly exhausted to the outside of the microwave oven via the electric chamber 4, first, between the bar plate 8 and the base plate 6. After entering the space, the direction is changed and exhausted outside the microwave oven 1 through the space between the air guide 16 and the back plate 10.

Therefore, by installing the bar plate 8 to mount the transformer 20, the exhaust structure for exhausting the exhaust gas exhausted from the gas oven range (not shown) under the microwave oven 1 is complicated. Is raised.

An object of the present invention is to solve the problems of the prior art as described above, and provides a hood-use microwave oven having a full length room having a mounting structure that the support surface for supporting the transformer is not deformed due to the load of the transformer. There is.

Another object of the present invention is to provide a hood-use microwave oven having an electric compartment having a supporting surface for supporting the transformer by a simple structure.

Still another object of the present invention is to provide a hood-use microwave oven having an exhaust structure for exhausting the exhaust gas of the gas oven range by a simple structure.

Hereinafter, a preferred embodiment of the hood-use microwave transformer mounting structure of the present invention will be described in detail with reference to the accompanying drawings.

As shown in FIG. 3, the base plate 56 forming the bottom surface of the microwave oven 51 forms the bottom surface of the electric compartment 54. The base plate 56 is coupled to a back plate 60 forming a rear surface of the microwave oven 51 and a front plate 62 forming a front surface of the microwave oven 51.

One side of the back plate 60 is equipped with a transformer 70 for boosting and outputting an applied voltage. The magnetron 68 for oscillating the microwave by receiving the voltage boosted by the transformer 70 is installed in the cavity side wall 52a that partitions the cavity 52 and the electric chamber 54.

In addition, an exhaust motor 72 serving as a driving source for forcibly drawing exhaust gas exhausted from a gas oven range (not shown) installed below the microwave oven 51 into the electric compartment 54 is provided on the upper surface of the cavity 53. .

The space formed by the cavity side wall 52a and the base plate 56 is a suction port 66. The suction port 66 is an inlet through which the exhaust gas of a gas oven range (not shown) is sucked into the electric chamber 54 by driving the exhaust motor 72.

Next, the operation of the embodiment by the microwave oven transformer mounting structure of the present invention having the configuration as described above will be described.

The transformer 70 is mounted on a support surface perpendicular to the base plate 56. Here, the support surface is a surface on which the transformer is mounted and supported. Since the support surface of the transformer 70 is vertical, deformation such as sag down does not occur due to the load of the transformer 70 as in the prior art.

In addition, in the present embodiment, the existing back plate 60 is used as the support surface without providing a separate support surface in the electrical equipment room 54.
