Hereinafter, with reference to Figure 5 looks at the circulation of the hood according to the present invention in another aspect of the present invention.

5 is a front perspective view showing a circulation device of a hood employing another embodiment according to the present invention. The front end of the inner space of the hood housing 500 is equipped with a circulator 700 for circulating a fluid that flows through the inner space of the hood 300. The circulation device 700 is provided with a partition plate 710 for partitioning a space between the hood housing 500 and forming a lower surface.

The partition plate 710 is formed in a plate shape having a predetermined thickness, and the circulation space 700 includes an inner space of the hood housing 500 together with a plurality of plate materials formed along an edge of the partition plate 710. The inner space of the) and the inner space of the hood housing 500 is partitioned.

That is, the upper side of the partition plate 710 is an internal space of the circulation device 700, and the lower side of the partition plate 710 is an outer space of the circulation device 700, that is, of the hood housing 500. It becomes internal space.

A plurality of panels are formed along the edge of the partition plate 710. A left panel 712 is formed at the left edge of the partition plate 710 to form a bottom surface of the circulation device 700, and a rear panel is formed at the rear edge of the partition plate 710 to form a rear surface of the circulation device 700. 714 is formed, and a right side panel 716 is formed at the right edge of the partition plate 710 to form the right side of the circulation device 700.

The left panel 712 and the rear panel 714 formed along the edge of the partition plate 710 and the upper end of the right panel 716 are in contact with the bottom surface of the panel forming the top surface of the hood housing 500. The inside of the circulation device 700 is formed to form one shielded space.

The centrifugal fan 720 is mounted on an upper surface of the partition plate 710, more specifically, an upper surface oriented to the left. The centrifugal fan 720 is formed in a disc shape having a predetermined diameter and thickness, and a plurality of fan wings are formed along the outer circumferential surface. The centrifugal fan 720 is rotated to suck the fluid from the lower side to discharge to the outside.

Accordingly, a fluid having a predetermined diameter is formed in the partition plate 710 of the portion where the centrifugal fan 720 is mounted, and the fluid flows into the hood housing 500 by the rotational movement of the centrifugal fan 720. A part of the fluid is allowed to flow into the inner space of the circulation device 700.

In front of the rear panel 714 is formed a circulating discharge guide 730 for guiding the fluid that flows to the internal space of the circulation device 700 by the rotational movement of the centrifugal fan (720). The circulation discharge guide 730 is formed in the shape of a long rectangular plate in the horizontal direction, it is formed long in the horizontal direction to have a predetermined thickness while having a height corresponding to the rear panel 714.

The circulation discharge guide 730 is formed to have a predetermined angle with the rear panel 714 so as to face forward toward the right side. That is, the circulating discharge guide 730 is positioned so as to be closer to the circulating discharge port 740, which will be described later as the centrifugal fan 720 is moved. The right end of the circulating discharge guide 730 is the right panel ( 716 is in contact with the left side.

As the circulation discharge guide 730 moves away from the centrifugal fan 720, the circular discharge guide 730 is located closer to the circulation discharge port 740 toward the outside of the centrifugal fan 720 by the rotational movement of the centrifugal fan 720. This is to guide the fluid so that the discharged fluid arrives at the circulation discharge port 740 with a constant amount and speed.

In other words, the fluid flowing from the lower side of the centrifugal fan 720 is rotated as the centrifugal fan 720 rotates, so that the fluid discharged from the centrifugal fan 720 moves away from the centrifugal fan 720. This is to guide the position close to 740. This is to allow the fluid away from the centrifugal fan 720 to be guided by the front surface of the circulation discharge guide 730 to flow to the circulation discharge port 740 more quickly.

Accordingly, the fluid flowing outwardly of the centrifugal fan 720 according to the rotational motion of the centrifugal fan 720 is guided by the circulation discharge guide 730 so that a certain amount of fluid is directed to the circulation discharge port 740. Through the outer space.

Looking at this in detail, assuming that the centrifugal fan 720 is rotated in a clockwise direction, the air flowing from the lower side of the centrifugal fan 720 rotates in a clockwise direction from the lower side to the center of the centrifugal fan 720. It flows and is discharged outward by a plurality of fan blades which rotate clockwise.

Since the centrifugal fan 720 is biased to the left side in the inner space of the circulation device 700, a larger amount of air flows to the right side of the centrifugal fan 720 and the right side of the centrifugal fan 720. A large amount of air to be flowed to the circulating discharge guide 730 is guided by the same amount of fluid flows to the circulating discharge port 740.

On the other hand, when the centrifugal fan 720 flows in a counterclockwise direction, the position of the centrifugal fan 720 is preferably mounted to be biased to the right in the inner space of the circulation device 700. In this case, the circulation discharge The guide 730 is preferably formed on the left side of the centrifugal fan 720.

Therefore, the mounting position of the centrifugal fan 720 is changed according to the rotational direction of the centrifugal fan 720, and the position at which the circulation discharge guide 730 is mounted is changed according to the mounting position of the centrifugal fan 720.

The front end of the circulation device 700 is formed with a circulating discharge port 740 through which the fluid flowing by the rotational movement of the centrifugal fan 720 is discharged to the external space of the circulation device 700. The circulation discharge port 740 has a low height and is formed long in the horizontal direction, and the front end portion is formed to be rounded downward.

A circulation flow guide 750 is formed below the circulation discharge port 740 to guide the flow direction of the fluid discharged through the circulation discharge port 740. The circulation flow guide 750 is rounded downward and then comes into contact with the front end of the inclined portion 420.

That is, the circulation flow guide 750 is formed in a substantially "⊂" shape when viewed from the right side, the rear end is formed in contact with the front end of the inclined portion 420 fluid discharged through the circulation discharge port 740 The suction is guided along the surface of the circulation flow guide 750 to the lower surface of the inclined portion 420, the suction through the suction port 460 by the suction force generated by the rotational movement of the first fan 510 It flows into the inside of the unit 400.

The fluid flowing out through the circulation discharge port 740 flows along the surface of the circulation flow guide 750 to guide the air formed in front of the inclined portion 420 to flow toward the suction port 460. do.

On the other hand, the centrifugal fan 720 is equipped with a single phase induction motor. Single-phase flow motors are less expensive than motors used in crossflow fans, and have the advantages of smaller volume and lighter weight.

Therefore, when the centrifugal fan 720 is used without using the crossflow fan, the product design is light and free of product design, and the volume is small, thereby reducing the space constraint.

Hereinafter, the operation of the hood and the circulation device configured as described above will be described with reference to FIG. 6.

Figure 6 is a side view showing the air flow of the hood employing a preferred embodiment of the present invention. Referring to the figure, when the user cooks food using the cooker 200, the user to discharge the heat and exhaust gas generated in the cooker 200 to the outer space to the hood 300 Will be activated.

When the user connects an external power source to the hood 300, the first fan 510 mounted inside the hood 300 rotates. The suction force is generated in the suction part 400 by the rotational motion of the first fan 510, and the fluid is drawn into the suction part 400 by the suction force generated in the suction part 400. Is inhaled.

The fluid sucked into the suction part 400 is guided by the fan housing 520 surrounding the first fan 510 to flow upward, and the fluid flowing upward is passed through the exhaust part ( Through 600) into the outer space.

A part of the fluid flowing into the exhaust part 600 flows into the circulation device 700 by the rotational movement of the centrifugal fan 720. The fluid that flows into the circulation device 700 flows outwardly of the centrifugal fan 720 and is guided by the circulation discharge guide 730 to allow the fluid to flow out of the inclined portion 420 through the circulation discharge port 740. It will flow to the front end.

At this time, the fluid flowing to the front end of the inclined portion 420 through the circulation discharge port 740 passes through the circulation discharge port 740 with the same amount and speed. The fluid flowing through the circulating discharge port 740 to the front end of the inclined portion 420 is guided by the flow guide 760 and flows along the surface of the flow guide 760, and again the lower side of the inclined portion 420. To flow.

The fluid flowing downward of the inclined portion 420 is sucked into the inner space of the suction portion 400 by the suction force of the suction portion 400 generated by the rotational movement of the first fan 510. .

The fluid flowing downward of the inclined portion 420 induces external air located in front of the inclined portion 420 to flow together into the inner space of the suction portion 400, thereby allowing the cooker 200 to flow. The fluid containing heat and exhaust gas generated when cooking food is not leaked to the outside of the hood 300, and guides the outside air to the inner space of the suction part 400. At the same time, the suction of the fan motor, which generates rotational power for the rotational motion of the first fan 510, may also be simultaneously performed.

The above embodiments are merely one embodiments of the present invention, and do not limit the present invention. Therefore, 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.

In the hood of the cooker according to the present invention as described above, a centrifugal fan is mounted inside the hood, and a part of the air exhausted by the centrifugal fan is circulated again and flows to the suction part, so as to be located above the front of the cooker. At the same time, the outside air is induced to flow into the inner space of the suction unit.

Therefore, the weight of the pan is lighter than that of the conventional technology of separating the space where the user is located from the space where the cooker is used by using a crossflow pan, and the weight of the product is lightened by the light of the pan. There is.

As the weight of the product becomes light, the effect of improving the installability and transportability of the product also occurs.

In addition, by inhaling the outside air that is located in the front upper side of the cooker without using the air curtain does not affect the cooking of the top burner portion, the user's stability and cooking time is also shortened.

In addition, by using a centrifugal fan without using a crossflow fan, the space occupied by the fan is reduced, thereby improving the usability of the inner space of the hood. An improved effect also occurs.

In other words, even if the hood of the same size is provided, a larger amount of fluid suction is possible by increasing the inner space of the hood.
