In addition, the first convection heater 110 and the first convection fan 120 are covered by the first cover member 140.

In detail, the first cover member 140 is fastened to the cavity rear wall 11a from the outside of the cavity 11.

Accordingly, a first heating chamber 142 is formed by the rear wall 11a of the cavity 11 and the first cover member 140, and is formed in the first heating chamber 142. The first convection heater 110 and the first convection fan 120 are located.

That is, the first convection heater 110 and the first convection fan 120 are provided outside the rear of the cavity 11, the first convection fan 120 is the first cover member 140 of the It is coupled to the shaft 132 of the fan motor 130 penetrated from the rear.

Here, the second cover member 240 is fastened to the cavity left wall 11b from the outside of the cavity 11. As a result, a second heating chamber 242 is formed by the cavity left wall 11b and the second cover member.

As described above, since each of the convection heaters 110 and 210 and the convection fans 120 and 220 are spatially separated by the cover members 140 and 240, the convection assemblies 100 and 200 may operate independently of each other. It becomes possible.

That is, one convection assembly is not affected by the other convection assembly in the operation of the convection heater and the convection fan.

Hereinafter, the relationship between each of the convection assemblies 100 and 200 and the relationship between the intake and outlet ports will be described in detail.

FIG. 4 is a diagram illustrating a relationship between a plurality of convex assemblies according to the present invention. In FIG. 4, a left wall and a rear wall of the cavity are two-dimensionally arranged.

Referring to FIG. 4, as described above, a pair of convex assemblies are provided on the outside of the cavity 11. At this time, the pair of convex assemblies are positioned in terms of the geometrical aspects of the various aspects so that the heated air can be circulated uniformly in the cavity 11. Hereinafter, the relationship between a pair of convection fans will be described with an example.

In detail, the pair of convection fans includes a first convection fan 120 and a second convection fan 220 and has a vertical height difference from each other.

That is, the axis of the first convection fan 120 is located higher than the axis of the second convection fan 220 based on the bottom surface of the cavity 11.

In this embodiment, the axis of the first convection fan 120 is located higher than the axis of the second convection fan 220, but vice versa.

In more detail, the axis of one convection fan is located on the upper side and the axis of the other convection fan is located on the lower side with respect to the imaginary horizontal center line A which bisects the cavity 11 up and down.

As such, when the axes of the pair of convection fans 120 and 220 are positioned at different heights, the air discharged by each of the convection fans 120 and 220 may be spread throughout the cavity 11. It becomes possible.

On the other hand, for more effective cooking of the food inside the cavity 11, the axis of the first convection pan 120 is closer to the cavity right wall, which is the other side of the cavity left wall 11b on which the second convection pan 220 is located. Is located.

When the axis of the first convection fan 120 is located close to the cavity left wall 11b, the air discharged through the side outlets 42 and 43 is immediately discharged through the rear outlets 32 and 33. It meets the discharged air and forms turbulence. In this case, it is good in terms of generation of turbulence, but the air discharged through the side outlets 42 and 43 is not smoothly moved to the right side of the cavity.

Therefore, in the present invention, the axis of the first convection fan 120 is located close to the cavity right wall, so that the air discharged through the side discharge ports 42 and 43 is smoothly moved to the right surface of the cavity and then moved. The turbulence is formed by meeting the air discharged through the rear discharge ports 32 and 33, so that the heated air can be evenly distributed in the cavity 11.

Meanwhile, a first suction port 31 is formed in the cavity rear wall 11a to allow air to be sucked into the first heating chamber 142, and the second heating chamber 242 is formed in the cavity left wall 11b. A second suction port 41 is formed to allow air to be sucked in.

In this case, each of the suction ports 31 and 41 is formed at a position corresponding to each of the convection fans 120 and 220 so that the air in the cavity 11 can be sucked in smoothly. Therefore, the second suction port 41 is formed at a position higher than the first suction port 31.

The rear discharge port may include a first rear discharge port 32 formed above the first suction port 31 and a second rear discharge port 33 formed below the first suction port 31. The side discharge port includes a first side discharge port 42 formed above the second suction port 41 and a second side discharge port 43 formed below the second suction port 41.

In this case, the first rear discharge port 32 is formed to be biased to the left based on the first suction port 31, and the second rear discharge port 33 is to be shifted to the right based on the first suction port 31. Is formed.

Similarly, the first side outlet 42 is biased to the left based on the second suction port 41, and the first side outlet 43 is to the right relative to the second suction port 41. Is formed.

In addition, the first rear discharge port 32 and the second rear discharge port 33 are formed to be symmetrical with respect to the axis of the first convection fan 120, and the first side discharge port 42 and the second side discharge port are formed. 43 is formed to be symmetrical with respect to the axis of the second convection fan 220.

Here, since the first and second rear discharge ports 32 and 33 are symmetrical with each other, and the first and second side discharge ports 42 and 43 are symmetrical, the position at which the first rear discharge port 32 is formed. Is higher than the position of the first side discharge port 42 as compared with the first rear discharge port 32, and the position at which the second rear discharge port 33 is formed is higher than the position of the second side discharge port 43 as contrasted. It is formed high.

As such, the air heated by each of the convection heaters 110 and 210 may be substantially evenly discharged into the cavity by the positional relationship between the rear discharge ports 32 and 33 and the side discharge ports 42 and 43.

The operation of the oven of the present invention will be described with reference to the structure of the suction outlet port and the positional relationship of each convection assembly.

5 is a view showing the flow of air inside the oven according to the present invention.

Referring to FIG. 5, when a user accommodates food in the cavity 11 and presses a start button, each of the convection heaters 110 and 210 generates heat, and each of the convection fans 120 and 220 is heated. Is rotated.

Then, the air inside the cavity 11 is sucked into the respective heating chambers 142 and 242 through the respective suction ports 31 and 41 and heated by the respective convection heaters 110 and 210. It is discharged into the cavity 11 through the rear discharge holes 32 and 33 and the side discharge holes 42 and 43.

In detail, the air discharged through the first side discharge port 42 meets the right side of the cavity while flowing along the upper side of the cooking chamber, and the flow direction thereof changes so that the second heating chamber 242 passes through the second suction port 41. Is inhaled.

In addition, the air discharged through the first rear discharge port 32 meets the door 14 while flowing along the upper side of the cooking chamber, and the flow direction thereof changes so that the first heating chamber passes through the first suction port 31. Inhaled at 142.

The air discharged through the second side discharge port 43 meets the right side of the cavity while flowing along the lower side of the cooking chamber, and the flow direction thereof changes so that the air is sucked into the second heating chamber 242 through the second suction port 41. do.

In addition, the air discharged through the second rear discharge port 33 meets the door 14 while flowing along the lower side of the cooking chamber, and the flow direction thereof changes so that the first heating chamber passes through the first suction port 31. Inhaled at 142.

At this time, the air discharged through the side discharge ports 42 and 43 faces the right side of the cavity 11, and the air discharged through the rear discharge ports 32 and 33 faces the front surface of the cavity 11. Therefore, the discharge direction of the air discharged through the side discharge ports 42 and 43 and the discharge direction of the air discharged through the rear discharge ports 32 and 33 may be viewed as crossing.

However, since each of the side discharge ports 42 and 43 is located at a position higher than the rear discharge ports 32 and 33 to be contrasted with each other, the air discharged through the side discharge holes 42 and 43 and the rear discharge holes 32 and 33 may be reduced. They do not actually meet until they change direction of flow. These discharged air meet each other after the flow direction is changed to form turbulent flow.

In this case, the food is heated while maintaining a constant flow until the air discharged through the discharge ports 32, 33, 42, 43 changes direction, and the turbulence meets each other while the direction of the air changes, thereby Can be heated evenly.

The present invention further includes the following examples.

The cover member of the present invention is fastened to the cavity on the outside of the cavity, but may alternatively be configured to be fastened to the cavity on the inside of the cavity. In this case, each heating chamber will be formed inside the cavity.

In addition, the suction port and the discharge port may be formed in the cover member. In this case, the suction port may be formed on a first surface of the cover member facing the cavity surface, and the discharge port may be formed on the first surface of the cover member or may form a peripheral surface of the first surface. It can be formed on two sides.

In addition, the present invention is described that the convection assembly is provided on one side of the cavity, it is also possible that the convection assembly is formed on both sides of the cavity. In this case the convection assembly provided at the rear of the cavity will preferably be located at the center of the cavity rear wall.

According to the present invention as proposed, since a plurality of heaters and fans can operate independently of each other, there is an effect that the heating air inside the cavity is uniformly distributed.

In addition, a plurality of heaters and fans are arranged up and down, and symmetrical, respectively, there is an effect that the air inside the cavity can be evenly distributed even more.

In addition, since heated air is discharged from the rear side and the one side of the cavity, the heating air inside the cavity can be made more uniform.

In addition, as air heated by a plurality of heaters is discharged in various directions inside the cavity, it is possible to appropriately cook various kinds of food.

In addition, since the plurality of heaters and fans are configured to be spatially independent, there is an effect that the rapid cooking is possible when the plurality of heaters and fans are operated at the same time.
