The camera cooling fan120is coupled to the fan holder110so that external air is suctioned through the inlet15, and the suctioned external air is transferred to the camera140to cool the camera140.

The camera140is disposed in the electrical component chamber50, and thus a temperature thereof may be increased by heat generated by the electrical components in the electrical component chamber50. The electrical component chamber50in which the camera is disposed is provided above the cooking compartment20, and thus the temperature thereof may be increased by heat generated in the cooking compartment20.

When the temperature of the camera140increases, a malfunction may occur in the camera140and an image quality thereof may be degraded, and thus the camera cooling fan120for cooling the camera140may be provided at an upper portion of the camera140.

The camera holder130on which the camera140is mounted is provided under the camera cooling fan120.

The camera holder130includes a mounting part131on which the camera cooling fan120is mounted, an outlet137through which air suctioned into the suction flow path111of the fan holder110to cool the camera140is discharged, and a first coupler139coupled to the exhaust duct53.

When the heat reflection coating layer175is provided on one surface of the glasses170and180, it is preferable for the surface on which the heat reflection coating layer175is provided to face the cooking compartment20.

Also, the glasses170and180may be formed of a tempered glass which is heat resistant or a borosilicate glass to prevent damage caused by heat. When the plurality of glasses170and180are provided, only a glass170disposed closest to the cooking compartment20may be formed of the tempered glass or the borosilicate glass.

The glass holder150includes a glass fixer151to which the plurality of second glasses180are fixed, a sealer152with an insertion hole153into which an end of the body tube143of the camera140on which the lens145is disposed is inserted, and a second coupler157coupled to the bottom surface57of the electrical component chamber50.

A space into which the end of the body tube143of the camera140in which the lens145is disposed is inserted is sealed by the second glass180positioned on top of the plurality of second glasses180and the sealer152to prevent a foreign material, such as dust, from entering the lens145.

Because only the end of the body tube143of the camera140at which the lens145is disposed is inserted into the insertion hole153, when a user looks at the camera140in the cooking compartment20, a remaining portion of the camera140except for the lens145is not visible and exposure of an unnecessary portion is prevented.

The glass holder150, as shown inFIG.9, may be provided to include the glass fixer151to which the plurality of second glasses180are fixed, an opening154opened to accommodate the end of the body tube143, and a gasket155detachably coupled to the opening154and having an insertion hole156into which the end of the body tube143is inserted.

In the case of the glass holder150shown inFIG.9, a space into which the end of the body tube143of the camera140at which the lens145is disposed is inserted is sealed by the gasket155and the second glass180positioned at the top of the plurality of second glasses180to prevent a foreign material, such as dust, from entering the lens145.

The third opening59is provided at the bottom surface57of the electrical component chamber50at a position corresponding to the second opening54provided in the exhaust duct53, and a glass holder coupling hole59ato which the glass holder150is coupled is provided around the third opening59.

The glass holder150is coupled to the bottom surface57of the electrical component chamber50by the fastening member B inserted into the glass holder coupling hole59aand the second coupler157, and the lens145disposed on the glass holder150captures the inside of the cooking compartment20through the third opening59provided in the bottom surface57of the electrical component chamber50and the second glasses180fixed to the glass holder150.

The first opening18bprovided on the ceiling18of the cooking compartment20is positioned to correspond to the second opening54provided on the exhaust duct53and the third opening59provided on the bottom surface57of the electrical component chamber50, and a glass bracket coupling hole18ccoupled to the glass bracket190on which the first glass170is mounted is provided around the first opening18b.

The glass bracket190includes a fourth coupler191positioned to correspond to the glass bracket coupling hole18c, and the glass bracket190is coupled to the ceiling18of the cooking compartment20by the fastening member B inserted into the glass bracket coupling hole18cand the fourth coupler191.

Because the glass bracket190is attachable to or detachable from the ceiling18of the cooking compartment20, when a foreign material is on the first glass170positioned above the cooking compartment20, the glass bracket190may be separated from the ceiling18of the cooking compartment20, and then the foreign material on the first glass170may be removed.

Therefore, the first glass170is positioned at the first opening18bprovided at the ceiling18of the cooking compartment20, the second glass180is positioned at the third opening59provided at the bottom surface57of the electrical component chamber50, and the lens145of the camera140may capture the inside of the cooking compartment20through the first glass170and the second glass180(seeFIG.10).

Also, transmission of heat in the cooking compartment20to the camera140may be doubly blocked by the first glass170and the second glass180, and thus the temperature of the camera140may be efficiently prevented from being increased.

FIG.10is a view showing that a blocking member in accordance with one embodiment of the present disclosure is provided between the camera and a cooling fan of the electrical component chamber, andFIG.11is a view showing that air discharged to the outside through the exhaust duct in accordance with one embodiment of the present disclosure bypasses and doesn't come into contact with the camera and is discharged to the outside by the blocking member.

As shown inFIGS.8,10, and11, a blocking member160for preventing air discharged to the outside through the exhaust duct53from coming into direct contact with the camera140is provided between the camera140positioned in the exhaust duct53and the electrical component chamber cooling fan51.

The blocking member160includes a third coupler161coupled to the bottom surface57of the electrical component chamber50and a support163supporting the exhaust duct53to prevent sagging of the exhaust duct53.

The blocking member coupling hole59bis provided on the bottom surface57of the electrical component chamber50to which the blocking member160is coupled, and the blocking member160is coupled to the bottom surface57of the electrical component chamber50by the fastening member B inserted into the third coupler161and the blocking member coupling hole59b.

When air suctioned from the outside by the electrical component chamber cooling fan51is discharged to the outside through the exhaust duct53, the blocking member160coupled to the bottom surface57of the electrical component chamber50allows the air to be discharged without coming into contact with the camera140by blocking a part of the exhaust duct53between the camera140and the electrical component chamber cooling fan51.

The air suctioned from the outside by the electrical component chamber cooling fan51cools the electrical components in the electrical component chamber50and is then discharged to the outside through the exhaust duct53, and thus the air discharged to the outside through the exhaust duct53has a high temperature. When high temperature air comes into direct contact with the camera140, the temperature of the camera140is increased, and thus the blocking member160is disposed between the camera140and the electrical component chamber cooling fan51to prevent the temperature of camera140from being increased.

Also, the support163supporting the exhaust duct53is provided at an upper portion of the blocking member160to prevent sagging of the exhaust duct53.

A part of the camera module100is coupled to an upper portion of the exhaust duct53, and thus a portion of the exhaust duct53to which the part of the camera module100is coupled may sag downward, and the support163of the blocking member160supports the exhaust duct53to prevent sagging of the exhaust duct53.

FIG.12is a view showing that air suctioned from the outside by a cooling fan of the camera and the cooling fan of the electrical component chamber in accordance with one embodiment of the present disclosure is discharged through the exhaust duct.

As shown inFIG.12, the electrical component chamber cooling fan51suctions external air into the electrical component chamber50through the suction port12aof the side panel12.

After the air suctioned into the electrical component chamber50cools the electrical components in the electrical component chamber50, the air is suctioned into the exhaust duct53by the electrical component chamber cooling fan51, and the air suctioned into the exhaust duct53is guided by the exhaust passage55and is discharged to the outside.

The external air suctioned into the inlet15of the upper panel14by the camera cooling fan120is moved through the suction flow path111, cools the camera140, and is then discharged through the outlet137.

Because the electrical component chamber cooling fan51cools the entirety of the electrical component chamber50, the electrical component chamber cooling fan51requires more air flow than that of the camera cooling fan120cooling the camera140, thereby having a larger size than the camera cooling fan120.

Therefore, the air discharged by the electrical component chamber cooling fan51to the exhaust duct53has a higher speed than the air discharged by the camera cooling fan120to the outlet137, and thus the air discharged into the outlet137is discharged to the outside along with the air discharged into the exhaust duct53by the electrical component chamber cooling fan51.

FIG.13is a view showing that a blocking member is integrally provided in a glass holder as another embodiment of the present disclosure, andFIG.14is a view showing that a blocking member is integrally provided in the camera holder as another embodiment of the present disclosure.

As shown inFIG.13, a blocking member158is not separately provided but is integrally provided in the glass holder150to prevent the air suctioned into the exhaust duct53by the electrical component chamber cooling fan51from coming into direct contact with the camera140.

Also, as shown inFIG.14, a blocking member138is not separately provided but is integrally provided in the camera holder130to prevent the air suctioned by the electrical component chamber cooling fan51and discharged into the exhaust duct53from being directly in contact with the camera140.

FIG.15is a schematic view of the oven in accordance with one embodiment of present disclosure.

As shown inFIG.15, the ceiling18of the cooking compartment20has the first opening18bso that the camera230disposed above the ceiling18of the cooking compartment20captures the inside of the cooking compartment20through the first opening18b.

The camera230is positioned above the ceiling18of the cooking compartment20, and thus a width of the first opening18bshould be determined according to a distance between the ceiling18of the cooking compartment and a lens235, a width of the cooking compartment20, and a distance between the lens235and the bottom surface of the cooking compartment20such that a food to be cooked in the cooking compartment20may be captured via the camera140.

When the width of first opening18bis f, the distance between the ceiling18of the cooking compartment20and the lens235is g, the width of cooking compartment20is w, and the distance between the lens235and the bottom surface of the cooking compartment20is h, it is preferable for the width of the first opening18bto satisfy the expression of “f≥g×w/h.”

FIG.16is a lateral cross-sectional view of an oven in accordance with another embodiment of the present disclosure,FIG.17is a view showing an inside of an electrical component chamber of the oven in accordance with another embodiment of the present disclosure,FIG.18is an exploded perspective view of a camera module in accordance with another embodiment of the present disclosure,FIG.19is a view showing that a part of the camera module in accordance with another embodiment of the present disclosure is coupled to an exhaust duct, andFIG.20is a view showing that the camera in accordance with another embodiment of the present disclosure is cooled by air suctioned from the outside by a cooling fan of the electrical component chamber.

As shown inFIGS.16to20, a camera module200is provided at the top of the cooking compartment20to capture a food to be cooked in the cooking compartment20.

The camera module100shown inFIGS.2to14includes the separate camera cooling fan120to cool the camera140, but the camera module200does not have a separate camera cooling fan to cool a camera230, and thus the camera230may be cooled by the electrical component chamber cooling fan51provided in the electrical component chamber50to cool the electrical components in the electrical component chamber50.

The camera module200includes a suction duct210communicating with the inlet15provided at the upper panel14of the main body10, a camera holder220on which the camera230is mounted, the camera230mounted in the camera holder220to capture the inside of the cooking compartment20, and at least one glass among glasses250and260provided under the camera230.

The suction flow path211communicates with the inlet15and guides the external air suctioned through the inlet15to be introduced to the camera230.

The outlet213discharges the air suctioned into the suction flow path211through the inlet15to cool the camera230to the outside of the camera module200.

The outlet213is provided to face an electrical component chamber cooling fan suction port52, and an upper end of the outlet213is provided to be higher than an upper end of the electrical component chamber cooling fan51.

An upper end of the outlet213is provided to be higher than the upper end of the electrical component chamber cooling fan51, and the outlet213is positioned at an upper portion of the electrical component chamber cooling fan suction port52.

The outlet213is positioned at the upper portion of the electrical component chamber cooling fan suction port52, and thus the external air is suctioned through the inlet15by a suction force of the electrical component chamber cooling fan51even though a separate camera cooling fan is not provided in the camera module200.

The partition wall215is provided between the suction flow path211and the outlet213, and thus the air suctioned into the suction flow path211is not discharged directly through the outlet213.

The camera holder220on which the camera230is mounted is provided at a lower portion of the suction duct210, and the suction duct210and the camera holder220are coupled by the fastening member B fastened to the camera holder coupling hole217provided in the suction duct210and a suction duct coupling hole225provided in the camera holder220.

Each of the suction flow path211and the outlet213of the suction duct210is provided to communicate with the camera holder220. Air suctioned into the suction flow path211is blocked from moving to the outlet213by the partition wall215and is transferred to the camera holder220, and the air transferred to the camera holder220cools the camera230.

The air that cooled camera230is discharged to the outside of the camera module200through the outlet213, and the air discharged through the outlet213is suctioned into the electrical component chamber cooling fan suction port52and is then discharged to the outside of the electrical component chamber50through the exhaust duct53.

The camera holder220includes a fixing hook221fixed to the suction duct210, a fixing protrusion223fixed to a glass holder240provided under the camera holder220, the suction duct coupling hole225coupled to the camera holder coupling hole217of the suction duct210, and a glass holder coupling hole227coupled to the glass holder240.

When the fixing hook221of the camera holder220is fixed to the suction duct210, the fastening member B is fastened to the camera holder coupling hole217of the suction duct210and the suction duct coupling hole225of the camera holder220, and thus the camera holder220is coupled to the suction duct210.

The camera230is mounted on the camera holder220, and the camera230is disposed in the electrical component chamber50, and thus a temperature of the camera230may be increased by the heat generated by the electrical component in the electrical component chamber50. The electrical component chamber50in which the camera230is disposed is provided above the cooking compartment20, and thus the temperature of the electrical component chamber50may be increased by the heat generated by the cooking compartment20.

When the temperature of the camera230increases, a fault may occur in the camera230and an image quality thereof may be degraded, and thus it is necessary to cool the camera230. In this case, the camera230is cooled by the external air suctioned into the inlet15by the electrical component chamber cooling fan51.

The camera230includes a mounting part231mounted on the camera holder220, a body tube233extending downward from the mounting part231and having a cylindrical shape, and a lens235disposed at an end of the body tube233to capture the inside of the cooking compartment20.

When the glasses250and260are provided as a single glass, it is preferable for the glasses250and260to have a thickness of 4 mm or more.

When the glasses250and260are divided into the first glass250and the second glass260, it is preferable for the sum of thicknesses of the first glass250and the second glass260to be 4 mm or more.

When the thickness of the glasses250and260is 4 mm or less, a heat reflection coating layer255is provided on one surface of the glasses250and260, as shown inFIG.6, or the heat reflection coating layers255may be provided on both surfaces of the glasses250and260, as shown inFIG.7.

When the heat reflection coating layer255is provided on one surface of the glasses250and260, it is preferable for the surface on which the heat reflection coating layer255to be provided to face the cooking compartment20.

Also, the glasses250and260may be formed of a tempered glass which is resistant to heat or a borosilicate glass to prevent damage caused by heat, and when the plurality of glasses250and260are provided, only a glass250disposed closest to the cooking compartment20may be formed of the tempered glass or the borosilicate glass.

One second glass260is fixed to the glass holder240, and the glass holder240includes a camera holder coupling hole241coupled to the camera holder220positioned at an upper portion of the glass holder240, and a fixing hole243to which the fixing protrusion223of the camera holder220is fixed.

After the fixing protrusion223of the camera holder220is fixed to the fixing hole243of the glass holder240, the fastening member B is fastened to the camera holder coupling hole241of the glass holder240and the glass holder coupling hole227of the camera holder220, and the glass holder240is coupled to the lower portion of the camera holder220.

A space in which an end of the body tube233of the camera230at which the lens235is disposed is positioned is sealed by the mounting part231of the camera230and the glass holder240to prevent a foreign material, such as dust, from entering the lens235.

The first opening18bis provided on the ceiling18of the cooking compartment, the second opening54is provided in the exhaust duct53, and the third opening59is provided on the bottom surface57of the electrical component chamber50. A configuration in which the camera230captures the inside of the cooking compartment20through the openings18b,54, and59is the same as the configuration shown inFIGS.2to14, and thus a description thereof will be omitted.

However, in the case of the camera module100shown inFIG.4, the coupling holes59aand59bto which the blocking member160and the glass holder150are coupled are provided around the third opening59. In the case of the camera module200shown inFIG.18, the glass holder240is coupled to the camera holder220, and the blocking member is not applied, and thus it is not necessary for a coupling hole to be provided around the third opening59.

The glass bracket270to which the first glass250is fixed includes a coupler271provided at a position corresponding to the glass bracket coupling hole18c, and the glass bracket270is coupled to the ceiling18of the cooking compartment20by the fastening member B inserted into the coupler271and the glass bracket coupling hole18c.

The glass bracket270is attachable to and detachable from the ceiling18of the cooking compartment20, and thus, when a foreign material is on the first glass250positioned above the cooking compartment20, the glass bracket270may be separated from the ceiling18of the cooking compartment20and the foreign material may be removed from the first glass250.

A flow of air cooling the camera230of the camera module200will be described with reference toFIGS.17and20.

As shown inFIGS.17and20, the external air is suctioned into the inlet15formed in the upper panel14of the main body and suction ports12aformed in both side panels12of the main body10by the electrical component chamber cooling fan51.

The air suctioned into the suction ports12acools the inside of the electrical component chamber50, is suctioned through the electrical component chamber cooling fan suction port52, and is then discharged to the outside of the electrical component chamber50through the exhaust duct53.

The air suctioned into the inlet15is transferred to the camera holder220through the suction flow path211to cool the camera230, and is then discharged through the outlet213, and the air discharged to the outlet213is suctioned through the electrical component chamber cooling fan suction port52and is discharged to the outside of the electrical component chamber50through the exhaust duct53.

While not shown in the drawings, when the space in which the camera230is positioned is in a vacuum due to a vacuum insulating material being foamed around the camera230, heat is not transmitted to the camera230, and thus a configuration for cooling the camera230may be omitted.

According to embodiments of the present disclosure, a camera is disposed above a cooking compartment such that an inside of the cooking compartment may be clearly captured, and a temperature of the camera disposed above the cooking compartment may be prevented from being increased.

Although particular shapes and directions have been mainly described in the above description of the oven with reference to the accompanying drawings, various modifications and changes may be made by those skilled in the art, and it should be recognized that such modifications and changes pertain to the scope of the present disclosure.
