The first exhaust opening 23 may connect to an exhaust duct 41. The exhaust duct 41 may be provided to discharge exhaust gas, which is generated in the cooking space 31 while a food item is cooked, out of the cooking appliance.
The exhaust duct 41 may be provided in a way that the lower end portion thereof connects to the upper portion of the cooking space 31 while the upper end portion thereof is disposed toward the upper portion of the rear surface of the cooking appliance 1. For example, the upper end portion of the exhaust duct 41 may be disposed at the rear of the cooktop part 20. In this embodiment, the upper end portion of the exhaust duct 41 connects to the first exhaust opening 23, for example.
Accordingly, exhaust gas generated in the cooking space 31 may flow into the exhaust duct 41 connected to the upper portion of the cooking space 31 and move upward, and be discharged upward on the rear surface of the cooking appliance 1 through the first exhaust opening 23 connected to the upper end portion of the exhaust duct 41.
A vent grille 60 may be disposed above the first exhaust opening 23. The vent grille 60 may be provided to cover the first exhaust opening 23, on the top plate 21.
The vent grille 60 is provided in a way that covers a partial area of the rear of the top plate 21, including the area in which the first exhaust opening 23 is disposed, from above. The vent grille 60 may also cover a portion being open upward in the rear space 34 that is a space between the rear surface of the cavity 31 and the rear cover 15, i.e., an upper end opening formed between the partition surface 30 a and the rear cover 15, from above. Thus, a space surrounded by the vent grille 60, the top plate 21 and the rear cover 15 may be formed in the vent grille 60.
In this embodiment, the vent grille 60 is formed into a cuboid the lower portion of which is open downward, for example. The vent grille 60 may be provided with at least one vent hole 61 through which exhaust gas discharged through the exhaust duct 41 passes. The vent hole 61 may be formed in a way that passes through the upper surface of the vent grille 60 vertically.
[Connection Structure Between Top Plate and Rear Panel]
FIG. 7 is an enlarged side view showing a portion of a rear of the cooking appliance in FIG. 5. FIG. 8 is an enlarged perspective view showing a portion of the rear of the cooking appliance in FIG. 5.
Referring to FIGS. 4 to 8, the rear space 34 may be formed between the cavity 31 and the rear cover 15. An upper end opening 49 may be formed at the upper end of the rear space 34. The upper end opening 49 may form a passage for opening the rear space 34 upward, behind the upper space 40.
The top plate 21 may connect to the rear cover 15 while covering the upper end opening 49 and the upper space 40 from above. The top plate 21 may include a main plate 210 and an extension plate 215.
The main plate 210 takes up most of the area of the top plate 21 and is disposed on the upper space 40. For example, the main plate 210 may be formed into a shape including a rectangle corresponding to the shape of the upper surface of the cavity 31.
The main plate 210 may include a concave surface 211 on which the cooktop heating part 22 is disposed, and an edge 212 which surrounds the concave surface 211.
The concave surface 211 may be disposed approximately at the center of the main plate 210 and takes up most of the area of the main plate 210. The cooktop heating part 22 may be disposed on the concave surface 211. In the case of a cooktop heating part 22 implemented as a heating device that uses gas as a fuel, at least a portion of a burner that burns gas may be exposed to the upper portion of the concave surface 211. To this end, a hole for exposing the burner to the upper portion of the concave surface 211 may be formed on the concave surface 211 in a way that passes through the concave surface 211 vertically.
The edge 212 may be provided at the front-rear edge and the left-right edge of the concave surface 211. The edge 212 may be concave further upward than the concave surface 211. For example, the central portion of the main plate 210, in which the concave surface 211 is disposed, may be depressed downward in the form of a rectangle.
The edge 212 of the main plate 210 may connect to the control panel 50, the side panel 17 and the like. For example, a portion of the edge 212, at the front of the main plate 210, may be coupled to the control panel 50, and portions of the edge 212, at both sides of the main plate 210 may be respectively coupled to the side panel 17.
As a result of the coupling among the edge 212, the control panel 50 and the side panel 17, the top plate 21 may be fixed to the upper portion of the upper space 40.
The extension plate 215 may extend from the main plate 210 rearward. The extension plate 215 may be provided to cover the upper end opening 49, on the upper space 40.
The extension plate 215 may correspond to the rear area of the top plate 21, and extend from the main plate 210 to the rear cover 15. Accordingly, the main plate 210 may be provided to approximately cover the upper area of the cavity 31, and the extension plate 215 may be provided to cover the rear area of the cavity, i.e., an area between the cavity 31 and the rear cover 15, from above.
In this embodiment, the main plate 210 and the extension plate 215 connect as the same surface while connecting in the front-rear direction, for example. A connecting structure of the main plate 210 and the extension plate 215 that connect as the same surface may cover the upper end opening 49 and the upper space 40 from above.
The extension plate 215 may be coupled to the rear cover 15 behind the cooktop part 20, specifically, behind the upper space 40 and at the rear of the rear space 34. To this end, the top plate 21 may further include a coupling part 217. The coupling part 217 may extend from the extension plate 215 and be coupled to the rear cover 15.
In this embodiment, the coupling part 217 is integrated with the main plate 210 and the extension plate 215, for example. The coupling part 217 may be formed in a way that extends from the extension plate 215 in a direction parallel with the rear cover 15.
For example, the coupling part 217 may extend from the end of the rear of the extension plate 215 downward. The coupling part 217, formed as described above, may be coupled to the rear cover 15 while contacting the rear cover 15 in the front-rear direction.
That is, the main plate 210, the extension plate 215 and the coupling part 217 may integrally connect such that a gap is not formed between the main plate 210 and the extension plate 215 and between the extension plate 215 and the coupling part 217, and while contacting the rear cover 15 in the front-rear direction, the coupling part 217 may be coupled to the rear cover 15.
Accordingly, the top plate 21 may be coupled to the control panel 50, the side panel 17 and the rear cover 15 while covering the rear space 34 and the upper space 40 from above. Accordingly, the top plate 21 may be fixed to the upper portion of the cooking appliance 1 while covering the upper space 40 and the upper end opening 49 from above.
[Operation of Cooking Appliance and Effect Thereof]
As described above, the top plate 21 may be fixed to the upper portion of the cooking appliance while covering the upper end opening 49 and the upper space 40 from above.
The top plate 21 may be provided with the first exhaust opening 23, and the vent grille 60 may be disposed on the first exhaust opening 23. The vent grille 60 may be provided to cover a partial area of the rear of the top plate 21, including the area in which the first exhaust opening 23 is disposed, from above.
The vent grille 60 may further include a link member 63. The link member 63 may be provided for a coupling between the vent grille 60 and the main body 10. For example, the link member 63 may protrude from the end of the rear of the vent grille downward. The link member 63 may be coupled to the main body 10, under the vent grille 60.
In an example, the link member 63 may be coupled to the rear cover 15. In another example, the link member 63 may be coupled to the end of the rear of the side panel 17 or the coupling part 217 of the top plate 21.
FIG. 9 is a rear view showing the cooking appliance in FIG. 2 without a rear cover, FIG. 10 is a view showing a flow of water in a cooking appliance of the related art, and FIG. 11 is a view showing a flow of water in the cooking appliance of one embodiment.
Referring to FIGS. 4 and 9, the rear space 34 may be disposed behind the cavity 11. Various types of electronic components associated with the function of the oven part 30 may be disposed in the rear space 34. For example, a circuit board 70 associated with the supply of power to the cooking appliance 1, a portion of a lighting device 75 installed in the oven part 30, and a convection motor 38 for rotating a convection fan disposed in the convection part 37 may be disposed in the rear space 34. Additionally, devices such as a valve 80 or a regulator 85 and the like associated with the supply of gas to the cooking appliance may be disposed in the rear space 34.
When water or foreign substances enter the rear space 34 in which the electronic components are disposed, the water or foreign substances may cause failure of the electronic components or accidents.
In a cooking appliance of the related art, a rear cover 15 is disposed behind a top plate 21 a, and the rear cover 15 is disposed behind a cavity 11, and a rear space 34 may be formed between the cavity 11 and the rear cover 15, as illustrated in FIG. 10.
Further, a gap 49 a is formed at the upper end of the rear cover 15, and the gap 49 a is formed between the top plate 21 a and the rear cover 15 to open the rear space 34 upward.
The rear cover 15 is coupled to the cavity 11 without being coupled to the top plate 21 a. The gap 49 a may be exposed to the upper portion of a cooktop part 20, behind the top plate 21 a.
A vent grille 60 a may be disposed over the gap 49 a. The vent grille 60 a is disposed to cover a partial area of the rear of the top plate 21 a, including the area in which an exhaust duct and an exhaust opening are disposed, from above. The gap 49 a is also covered by the vent grille 60 a.
A vent hole 61 a passes through the vent grille 60 a vertically, and exhaust gas discharged through the exhaust opening is discharged out of the upper portion of the vent grille 60 a through the vent hole 61 a.
Through the vent hole 61 a, water or foreign substances may enter the space in the vent grille 60 a. The water or the foreign substances having entered the space in the vent grille 60 a may enter the rear space 34 through the gap 49 a formed between the top plate 21 a and the rear cover 15.
That is, in the cooking appliance of the related art, water or foreign substances are highly likely to enter the rear space 34 through the gap 49 a exposed to the inside the vent grille 60 a.
Unlike the cooking appliance of the related art, the cooking appliance of this embodiment has a top plate 21 that covers the upper end opening 49 and the upper space 40, as illustrated in FIGS. 4 and 11.
For example, the main plate 210, the extension plate 215 and the coupling part 217 integrally connect such that a gap is not formed between the main plate 210 and the extension plate 215 and between the extension plate 215 and the coupling part 217, and the coupling part 217 may be coupled to the rear cover 15 while contacting the rear cover 15 in the front-rear direction.
Accordingly, the top plate 21 is coupled to the control panel 50, the side panel 17 and the rear cover 15 while covering the upper space 40 and the rear space 34 from above. Thus, the top plate 21 may be fixed to the upper portion of the cooking appliance 1, while covering the upper space 40 and the upper end opening 49 from above.
That is, a passage, through which water or foreign substances enter the rear space 34 from the upper portion of the cooking appliance 1, is blocked by the top plate 21, thereby effectively preventing the water and foreign substances from entering the rear space 34.
Further, in this embodiment, a connecting portion between the top plate 21 and the rear cover 15 is disposed at the rear of the cooking appliance 1 instead of being disposed toward the upper portion of the cooking appliance 1, and the top plate 21 and the rear cover 15 are coupled in the front-rear direction. Thus, it is less likely that water or foreign substances enter the cooking appliance through the coupling portion between the top plate 21 and the rear cover 15, and the invasion of water or foreign substances into the rear space 34 is effectively prevented.
Since water or foreign substances having fallen to the upper portion of the cooking appliance through the vent grille 60 are prevented from entering the electronic components disposed in a space formed between the rear surface of the cooking appliance 1 and the rear cover 15 through the vent grille 60 as described above, the failure of the electronic components, caused by the water or foreign substances, may be effectively prevented.
[Control Panel and Peripheral Structure Thereof]
FIG. 12 is an exploded perspective view showing a state in which a cooktop part and a control panel are separated from the cooking appliance of one embodiment, and FIG. 13 is a cross-sectional view showing a flow of cool air in the cooking appliance of one embodiment.
Referring to FIGS. 12 and 13, the control panel 50 may be disposed at the front of the upper space 40, and disposed on the door 32. The control panel 50 may include a control panel cover 55. The control panel cover 55 may form the exterior of the control panel 50 and accommodate various types of components constituting the control panel 50.
The control panel cover 55 may form the exteriors of the front surface, lateral surfaces and lower surface of the control panel cover 55, and accommodate the display 52. The lower surface of the control panel cover 55 may close between the door 32 and the display 52.
The door 32 disposed under the control panel 50 may have a path for the flow of air, therein. Additionally, an air flow hole may be disposed in the lower portion of the door 32. Further, a discharge hole 32 a may be disposed on the upper surface of the door 32, which faces the control panel 50. The air flow hole, the path and the discharge hole 32 a may be formed in a way that they pass through the door 32.
The air flow hole may form a passage through which external air flows into the path in the door 32, and the discharge hole 32 a may form a passage through which the air having passed through the path in the door 32 is discharged out of the door 32. The discharge hole 32 a may be formed in a way that passes through the upper surface of the door 32 vertically, and the air having passed through the path in the door 32 may be discharged upward through the discharge hole 32 a.
Further, a cooling fan 45 may be disposed behind the control panel 50 and the door 32. The cooling fan 45 may be disposed near the rear cover 15 while being disposed in the upper space 40.
In an example, the cooling fan 45 may include a turbo fan disposed on the upper surface of the cavity 11. The cooling fan 45 may suction air in front of the upper space 40 and discharge the air toward the vent grille 60. The air discharged by the cooling fan 45 may pass through the second exhaust opening 24 formed in a way that passes through the top plate 21 and through the vent grille 60, and be discharged out of the upper portion of the cooking appliance 1.
[Relationship Between Structure of Control Panel and Structure of Top Plate]
Ordinarily, when the cooking appliance, specifically, the oven part 30 performs a cooking operation, the heating part operates. While the heating part operates, the cooling fan 45 may also operate.
When the cooling fan 45 operates, external air in front of the cooking appliance 1 may flow into the upper space 40 through the intake opening 14 that is formed in a way that passes through the front panel 13. The air having flown into the upper space 40 may pass through the upper space 40 while cooling components such as the display 52 disposed on the control panel 50 or the circuit board and the like, and then pass through the second exhaust opening 24 and the vent grille 60 and be discharged out of the upper portion of the cooking appliance 1.
Along the way, external air in front of the main body 10 and under the main body 10 is suctioned through the air flow hole disposed in the lower portion of the door 32, and then discharged through the discharge hole 32 a disposed in the upper portion of the door 32 while cooling the door 32. The air discharged out of the upper portion of the door 32 through the discharge hole 32 a may flow into the upper space 40 through the intake opening 14 that is formed in a way that passes through the front panel 13.
In this embodiment, the lower surface of the control panel cover 55 closes between the door 32 and the display 52, and a passage for connecting between the discharge hole 32 a of the door 32 and the display 52 is not formed on the lower surface of the control panel cover 55.
Accordingly, the air discharged out of the upper portion of the door 32 through the discharge hole 32 a of the door 32 may flow into the upper space 40 immediately through the intake opening 14 without contacting the display 52. That is, air heated during the process of cooling the door 32 may be discharged through the discharge hole 32 a and then flow into the upper space 40 immediately without affecting the display 52.
The hot air discharged from the door 32 hardly affects the display 52 disposed on the door 32. Thus, damage to the display 52 or operational errors of the display 52, caused by the hot air discharged from the door 32, may be effectively prevented.
The display 52 is a heat-generating component that generates a large amount of heat. Accordingly, if the display 52 does not cool properly, the performance of the display 52 may deteriorate or the failure of the display 52 may occur.
One of the effective ways to cool the display 52 is to provide a cooling hole for cooling the display 52 at the control panel cover 55 that surrounds the display 52.
If the cooling hole is disposed on the front surface or the upper surface of the control panel cover 55, the cooling hole is exposed plainly, deteriorating aesthetic qualities. Additionally, water or foreign substances are highly likely to enter the control panel 50 through the cooling hole.
If the cooling hole is disposed on the lateral surface of the control pane cover 55, a distance between the cooling hole and the display 52 increases, and the surface area of the cooling hole may not be ensured sufficiently. That is, if the cooling hole is disposed on the lateral surface of the control panel cover 55, the display 52 may not cool properly.
To solve the above problems, the cooling hole may be provided on the lower surface of the control panel cover 55, preferably. However, the discharge hole 32 a of the door 32 and the cooling hole of the control panel 50 face each other. In this case, hot air discharged from the door 32 may flow into the control panel 50 through the cooling hole, adversely affecting the display 52.
To prevent this from happening, in this embodiment, a passage for connecting between the discharge hole 32 a of the door 32 and the display 52 is formed on no surface including the lower surface of the control panel cover 55. Thus, the hot air discharged from the door 32 hardly affects the display 52 disposed on the door 32.
However, if no cooling hole is disposed at the control panel cover 55, there is little possibility that the display 52 cools properly. The occurrence of the problem may be suppressed based on the effect of the above-described coupling between the top plate 21 and the rear cover 15.
In this embodiment, the main plate 210, the extension plate 215 and the coupling part 217 may integrally connect such that a gap is not formed between the main plate 210 and the extension plate 215 and between the extension plate 215 and the coupling part 217, and the coupling part 217 may be coupled to the rear cover 15 while contacting the rear cover 15 in the front-rear direction.
Accordingly, the top plate 21 may be coupled to the control panel 50, the side panel 17 and the rear cover 15 while covering the upper space 40 and the rear space 34 from above, such that the top plate 21 is fixed to the upper portion of the cooking appliance 1 while covering the upper space 40 and the upper end opening 49 from above.
The top plate 21 may be coupled to the rear cover 15 as a result of the coupling between the coupling part 217 and the rear cover 15, and seal the upper portion of the cooktop part 20. That is, the upper end opening 49 may be sealed by the top plate 21, and a space around the cooling fan 45 disposed near the upper end opening 49 may be surrounded and sealed by the top plate 21, the rear cover 15 and the cavity 31.
When the perimeter of the cooling fan 45 is sealed as described above, the intensity of air current generated by the cooling fan 45 may increase efficiently. As the intensity of air current generated by the cooling fan 45 increases, the efficiency of cooling components such as the display 52 or the circuit disposed on the control panel 50 and the like may improve.
That is, in the cooking appliance of this embodiment, since the upper end opening 49 near the cooling fan is sealed as a result of the coupling between the top plate 21 and the rear cover 15, the intensity of air current generated by the cooling fan 45 may efficiently increase, thereby effectively cooling the display 52 disposed on the control panel 50.
The cooking appliance 1 of this embodiment may increase the intensity of air current for cooling such that the display 52 cools effectively although the cooling hole is not formed in the lower portion of the control panel 50. Thus, the cooking appliance 1 of this embodiment may help to cool the display 52 effectively, while preventing hot air discharged from the door 32 from affecting the display 52.
The subject matter of the present disclosure is described with reference to the embodiments illustrated in the drawings, but the embodiments are merely illustrative. Those of ordinary skill in the art to which the disclosure pertains can understand that various modifications and other equivalent embodiments are drawn from the above embodiments. Therefore, the technical scope of the present disclosure should be defined by the appended claims.
