For convenience of description, as shown in
Reference will now be made in detail to embodiments of the disclosure, examples of which are illustrated in the accompanying drawings.
The cooking apparatus 1 may be disposed indoors. For example, the cooking apparatus 1 may be disposed in a kitchen and may be coupled to and installed in a cabinet 3.
The cooking apparatus 1 may be configured to cook food. The cooking apparatus 1 may include the cooktop 10 configured to cook food and the hood 30 configured to suction air containing contaminants generated in a process of cooking food. The cooking apparatus 1 may be a hood-integrated cooktop in which the hood 30 is provided under the cooktop 10.
The cooktop 10 may be an induction cooktop, that is an electric cooktop. The cooktop 10 may include a plurality of coils (not shown) corresponding to positions L1, L2, L3, and L4 in which a cooking vessel may be placed. A current in which a magnitude thereof changes over time may be applied to the coil. As the current is applied to the coil, a magnetic field may be formed around the coil. As the current applied to the coil changes, the magnetic field formed around the coil may also change. An eddy current according to a change in the magnetic field may flow on a surface of a cooking vessel 2 that is in contact with an upper plate 11, thereby heating the cooking vessel.
In the drawings, it is illustrated that the cooktop 10 is an induction cooktop, that is an electric cooktop, but the disclosure is not limited thereto. The type of cooktop 10 may not be limited thereto. For example, the cooktop 10 may be a radiant cooktop among electric cooktops.
By using a method in which the current flows using a magnetic field, the induction cooktop may directly heat a cooking vessel without heating the upper plate. Accordingly, the risk of burns may be reduced. However, only a cooking vessel formed of a metal to which a magnet is attached may be used as a cooking vessel, but glass, ceramics, or aluminum may not be used. By using a method in which electricity flows through a nichrome wire under a ceramic plate, the radiant cooktop may heat an upper plate and a cooking vessel. Accordingly, the upper plate may be heated and thus there is the risk of burns. However, as long as a bottom is flat, all cooking vessels may be used for the radiant cooktop, except for direct-fired cooking vessel. The cooktop 10 may also be a hybrid capable of using both the magnetic field and the radiant heat. The hybrid may be a product that has the advantages of both induction cooktop and radiant cooktop.
The cooktop 10 may be a gas cooktop in addition to an electric cooktop. For example, the cooktop 10 may be a gas stove. However, in this drawing, an induction cooktop, which is an electric cooktop, will be described as an example.
The hood 30 may be configured to discharge air containing contaminants generated from the cooktop 10 to the outside. Alternatively, the hood 30 may allow air containing contaminants to pass through a deodorization filter (not shown) and then circulate the filtered air back to the inside. However, in this drawing, it is illustrated that the hood 30 includes a duct 40 configured to discharge air to the outside.
The cooking apparatus 1 may be a hood-integrated cooktop in which the cooktop 10 and the hood 30 are combined. The hood 30 may be coupled to a lower part of the cooktop 10. However, the disclosure is not limited thereto, and the cooktop 10 and the hood 30 may be integrally formed with each other.
Because the hood 30 is disposed below the cooktop 10, an upper space of a place in which the cooking apparatus 1 is installed may be secured. In addition, because the hood 30 is disposed at the rear of the cooktop 10, it is possible to secure a front space. For example, referring to
That is, the cooking apparatus 1 is a hood-integrated cooktop, and space utilization may be improved.

Because the chamber outlet 58 is disposed toward the second direction Y from the suction port 15, the front side of the suction port 15 may have weaker suction power than the rear side. Therefore, when the cooking vessel 2 is placed at the positions L2 and L4 provided in a front portion of the cooktop 10, the air suction power may be lower than when the cooking vessel 2 is placed at the positions L1 and L3 provided in a rear portion of the cooktop 10.
Therefore, a vortex may be generated in the rear portion of the inner space S of the chamber 50, and thus noise may be generated.
At this time, because the guide rib 60 defines a plurality of flow paths inside the chamber 50, the air sucked into the suction port 15 may be moved along the branched flow paths to the chamber outlet 58.
Particularly, the air sucked into the suction port 15 may be moved through a first flow path F1 formed between the first partition rib 62 and the second sidewall 53b, or a second flow path F2 formed between the first partition rib 62 and the third partition rib 64, or a third flow path F3 formed between the third partition rib 64 and the second partition rib 63, or a fourth flow path F4 formed between the second partition rib 63 and the third sidewall 53c.
Therefore, even when the cooking vessel 2 is placed at any of the various positions L1, L2, L3, and L4 provided on the upper plate 11 of the cooktop 10, the distribution of the flow velocity of the air sucked through the suction port 15 may be uniform.
In addition, it is possible to reduce an intensity of turbulence by reducing the deviation of the flow velocity inside the chamber 50. Air sucked into the chamber 50 through the suction port 15 may be moved uniformly to the chamber outlet 58.
The first partition rib 62 and/or the second partition rib 63 and/or the first sidewall 53a and/or the second sidewall 53b and/or the third sidewall 53c may include a curved surface. Accordingly, the flow resistance of the air moving through the flow path may be reduced.
In addition, a cross-sectional area of the flow paths F1, F2, F3, and F4 may be reduced toward the chamber outlet 58. Therefore, it is possible to gradually increase the flow rate of the air moving through the flow path.
On the other hand, in this drawing, it is illustrated that three partition ribs 62, 63, and 64 are provided, but the disclosure is not limited thereto. For example, two or less of the partition ribs 62, 63, and 64 may be provided or four or more of the partition ribs may be provided.
In addition, in this drawing, it is illustrated that the flow path is branched into four flow paths, but the disclosure is not limited thereto. For example, the flow path may be branched into three or less of flow paths, or branched into five or more of flow paths.
The guide rib 60 may include a protruding rib 66. The protruding rib 66 may protrude toward the inside of the chamber body 51 from the sidewall 53. The protruding rib 66 may extend from the first sidewall 53a toward the chamber outlet 58.
The protruding rib 66 may be disposed in a direction opposite to the direction, in which the chamber outlet 58 is disposed, from the suction port 15. As for the inner space S of the chamber 50, an influence of the blower fan 31 may be reduced and a suction force may be reduced as further away from the chamber outlet 58.
Particularly, air sucked through the suction port 15 may be biased toward the rear side of the chamber 50. Therefore, a vortex may be generated in the front portion of the chamber 50, and noise may be generated accordingly.
The protruding rib 66 may be provided to reduce a space area of a portion having weak suction force in the inner space S. The protruding rib 66 may extend from the first sidewall 53a toward the second direction Y, thereby reducing an area of the front portion of the inner space S. Therefore, it is possible to reduce noise by preventing generation of vortex.
The protruding rib 66 may extend from the center of the first sidewall 53a toward the center of the chamber outlet 58. The protruding rib 66 may be disposed to face the third partition rib 64.
The protruding rib 66 may extend toward the suction port 15 from the first sidewall 53a. The suction port 15 may include a fourth side 19 facing the third side 18. The fourth side 19 may be adjacent to the first sidewall 53a. A first end of the protruding rib 66 may be disposed on the first sidewall 53a and a second end 66a may be disposed to correspond to the fourth side 19 of the suction port 15.
The second end 66a of the protruding rib 66 may be disposed on the fourth side 19 of the suction port 15 to allow the air introduced into the suction port 15 to be divided into the left side and the right side. The protruding rib 66 may be provided to define the first flow path F1 and the fourth flow path F4. The protruding rib 66 may guide the air sucked into the front of the suction port 15 to be divided into the left side and the right side to prevent the vortex.
The guide rib 60 may be provided to be in contact with the lower plate 12 of the cooktop 10. The guide rib 60 may protrude from the bottom surface 52 of the chamber body 51 toward the first direction Z. The guide rib 60 may be in contact with the lower surface 12b of the lower plate 12.
Therefore, the air introduced into the chamber body 51 through the suction port 15 may be branched into the plurality of flow paths F1, F2, F3, and F4 by the guide rib 60, and air branched into each of the flow paths F1, F2, F3, and F4 may be moved toward the chamber outlet 58 without the loss of flow rate or without mixing with each other.
As is apparent from the above description, it is possible to improve utilization of space of a cooking apparatus.
Further, it is possible to reduce noise of a cooking apparatus.
