Therefore, due to such a shape, a space in which outside air is introduced into the rear end of the side cover 240 is formed, and the outside air flows into the electric chamber (reference numeral 800 in FIG. 7).

Hereinafter, the structure of the electric chamber (reference numeral 800 in FIG. 7) will be described in detail with reference to the accompanying drawings.

6 is a perspective view showing a state in which the electric chamber cover of the built-in oven according to the present invention is removed.

As shown in the figure, the bottom of the electric chamber (reference numeral 800 in FIG. 7) is formed by an insulator lower 820. The insulator lower 820 is formed in a substantially rectangular plate shape, and distinguishes a space in which the oven cavity 120 is formed from a space of the electric compartment (reference numeral 800 in FIG. 7). The inner space is partitioned in the transverse direction.

Looking at the interior of the battlefield room (reference numeral 800 in FIG. 7), a cooling fan 860 is provided at approximately the center of the second half of the battlefield room (reference numeral 800 in FIG. 7). The cooling fan 860 forcibly discharges the heated air inside the electric compartment (reference numeral 800 in FIG. 7) to the outside and sucks the outside air to cool the inside of the electric compartment (reference numeral 800 in FIG. 7). For example, centrifugal fans such as Siroccofan are used.

The cooling fan 860 is mounted by the cooling fan guide 862 so that the mounting position can be fixed in the interior of the electric compartment (reference numeral 800 in FIG. 7). The cooling fan guide 862 guides the flow of air blown by the cooling fan 860 as well as fixing the mounting position of the cooling fan 860, except for a part of the cooling fan 860. It is formed to surround the other portion, it is coupled to communicate with the air guide 840 to be described below.

The air guide 840 is provided in front of the cooling fan guide 862, the air inside the electric chamber (reference numeral 800 in FIG. 7) forcibly blown from the cooling fan 860 is the outside of the oven 100 To be discharged.

Accordingly, the air guide 840 has both side ends and the front end portion bent downward, and the bent portion is coupled with the insulator lower 820, between the upper surface of the insulator lower 820 and the inside of the air guide 840. A predetermined space is formed in the. And the rear end of the space is connected to the exhaust hole 720, the air inside the electrical chamber (reference numeral 800 in Fig. 7) is discharged through the exhaust hole (720).

In addition, the air guide 840 is formed so that the width is gradually wider from the front end to the rear end, so that the rear end of the air guide 840 all the plurality of exhaust holes 720 formed in the front panel 700 It is mounted to include.

On the other hand, the above-described air guide 840 is equipped with the above-described electrical components 880, PC (PCB: 882) and the LCD display 884 and the like. In addition, the PC 882 and the LCD display 884 are mounted in a line in the direction of the cooling fan 860 in the outside air inlet 362, in particular, parts such as TFT LCD (TFT LCD) Since it is a sensitive device, it is most preferable to mount the lower side of the intake hole (221 in FIG. 5) formed at the center and the right side of the extension plate 222 so that the outside air flowing from the outside air inlet 362 is directly contacted. .

Hereinafter, the operation of the oven according to the present invention having the configuration as described above will be described in detail with reference to FIG.

First of all, the present invention has been described as an example of a built-in electric oven, which is applicable to a built-in oven.

Figure 7 is a perspective view showing the flow of air inside the electrical chamber of the built-in oven according to an embodiment of the present invention, as shown in the figure, when the user operates the oven 100, the cooling fan 860 is operated, By the operation of the cooling fan 860, the outside air flows into the intake hole 221 through the outside air inlet 362 formed in the coupling end 360 of the control panel 300. That is, the cooling fan 860 sucks the air in the interior of the electric chamber 800 by rotation to make the inside of the electric chamber 800 into a low pressure part having a lower air pressure than the outside, and thus the external air pressure is relatively high. Air is easily introduced into the electric chamber 800 through the intake hole 221.

The outside air introduced in this way circulates inside the electric chamber 800 to cool the electric parts contained therein (refer to reference numeral 880 of FIG. 6), the PC 882, the LCD display 884, and the like. Outside air is again collected by the air guide 840 by the suction force of the cooling fan 860. The outside air collected by the air guide 840 is transferred to the exhaust hole 720 communicating with the air guide 840, and the transferred outside air is external to the oven 100 through the exhaust hole 720. Is discharged.

In the air circulation process, the outside air inlet 362 secures an outside air inflow space that is relatively insufficient in the built-in oven 100. That is, as shown in the top / bottom / left / right / rear of the oven 100 is shielded by the cabinet or the wall so that the outside air does not flow smoothly, the outside air inlet 362 is the upper surface of the cabinet Open spaces are formed to allow the smooth inflow of outside air.

In addition, since the suction space of the outside air is narrow, the outside air flows into the low pressure portion formed by the cooling fan 860 at a high speed, and the outside air introduced at a high speed has a relatively low temperature, thereby making the electric component 880 easier. ) And the LCD display 884 and the PCB 882 are cooled.

In addition, the intake hole 221 is located at the lower side of the outside air inlet 362 and the upper side of the electric component 880, and the outside air introduced from the outside air inlet 362 to the electric component 880. It is allowed to enter immediately and cooled.

The scope of the present invention is not limited to the above-exemplified embodiments, and many other modifications based on the present invention will be possible to those skilled in the art within the above technical scope.

For example, it will be possible to mount the PCB and the LCD display and the electronic components to be located in a zigzag direction in the direction of the cooling fan from the inlet air, it is also possible to vary the shape and quantity of the intake hole. It is also possible to modify the shape of the outside air inlet, but it will be apparent that the deformation and the change of the mounting position of the shape are included in the technical idea of the present invention.

The air flow structure of the oven according to the present invention as described above in detail has the advantage that the intake hole is located on the rear side of the control panel so that the space opened to the outside is not exposed and the appearance is beautiful.

In addition, the outside air inlet is formed on the upper side of the intake hole, and there is an advantage that the outside air flows smoothly into the intake hole even when the outside air is built in.

In addition, since the intake hole is located at the rear side of the control panel, the inflow of dust and dirt is minimized, so that the accumulation amount of dust and dirt on the electric component is reduced.

In addition, since the position of the intake hole is located on the lower side of the outside air inlet and the upper side of the electric component, external air flows directly into the electric component, thereby increasing the cooling efficiency.
