Patent Description:
Cooking appliances are one kind of home appliances for cooking food and are installed in a kitchen space to cook food according to an intention of a user. These cooking appliances may be classified into various types according to a heat source or type being used and the type of fuel.

The cooking appliances are classified according to the type of cooking, the cooking appliances may be classified into open-type cooking appliances and closed-type cooking appliances according to the shape of a space in which food is placed. Closed-type cooking appliances include ovens, microwave ovens, and the like, and open-type cooking appliances include cooktops, hops, griddles, and the like.

A closed-type cooking appliance is a cooking appliance provided with a space in which food is located and which is shielded to cook the food by heating the shielded space. The closed-type cooking appliance is provided with a cooking chamber provided with a space which is shielded when food is cooked while the food is placed therein. The cooking chamber provides a space in which the food is substantially cooked.

Closed-type cooking appliances are roughly classified into gas ovens and electric ovens according to the type of a heat source. In a gas oven, a gas is used as a fuel, and as the gas is supplied to a plurality of burners and the burners are ignited, food is cooked by a flame generated while the supplied gas is burned. Unlike the gas oven, in an electric oven, electricity is used as a heat source, and food is cooked by heat emitted from heaters while the plurality of heaters are operated.

A door that selectively opens or closes the cooking chamber may be rotatably provided in the closed-type cooking appliance. The door is rotatably installed in a body, in which the cooking chamber is formed, using a door hinge provided between the body and the door, and as the door is rotated about a portion coupled to the body through the door hinge, the cooking chamber may be selectively opened or closed.

The heat source is provided in an inner space of the cooking chamber opened or closed by the door and heats the cooking chamber. A gas burner, an electric heater, or the like may be used as the heat source.

In addition, the closed-type cooking appliance is provided with an exhaust duct. The exhaust duct is provided to discharge, to the outside of the cooking appliance, combustion gas generated while the food is cooked inside the cooking chamber.

The exhaust duct is provided so that a lower end thereof is connected to an upper portion of the cooking chamber and an upper end thereof is disposed on the rear upper side of the cooking appliance. The combustion gas generated in the cooking chamber flows into the exhaust duct connected to the upper portion part of the cooking chamber, flows upward, and is discharged upward from the rear surface of the cooking appliance through a vent grill provided above the exhaust duct.

At least one exhaust hole through which the combustion gas discharged through the exhaust duct is to pass is provided in the vent grill, and the exhaust hole is formed to vertically pass through the vent grill.

In recent years, complex cooking appliances have been proposed in which the closed-type cooking appliance and the open-type cooking appliance are installed at the same time, a plurality of heat sources are combined, and thus various types of food may be cooked and a plurality of pieces of food may be cooked simultaneously. The cooking appliance in which the plurality of heat sources are installed is accompanied by a flow path of cooling air for cooling the plurality of heat sources and electronic components.

In the complex cooking appliance, the open-type cooking appliance is located on the closed-type cooking appliance. Further, in the open-type cooking appliance, the plurality of heaters or the plurality of burners are installed so that a plurality of dishes may be cooked simultaneously.

That is, when a user cooks an oven dish such as a barbecue dish or bread or a roast dish such as a grilled fish, the cooking is performed using the closed-type cooking appliance, and when the user cooks a general dish in which food is heated while being placed in a container, the cooking is performed using the open-type cooking appliance of which an upper portion is open.

One of the most commonly used open-type cooking appliances is a gas stove-type open cooking appliance, which cooks food using a flame generated when gas is burned by the burner.

The burner provided in this open-type cooking appliance generally includes a burner body, a burner head, and a burner head cap.

Accordingly, the burner body having a flow path through which a gas is supplied is fixedly installed inside a cooktop case forming an outer shape of the open-type cooking appliance, the burner head through which the gas supplied through the flow path is discharged is installed above the burner body, and the burner head cap is installed above the burner head.

A gas supply pipe for supplying a gas and a nozzle for injecting the gas may be mounted on the burner body. Further, the burner head may be located on a member defining an upper surface of the open-type cooking appliance, for example, an upper surface of a top plate, and the burner head cap is seated on the upper side of the burner head.

In the complex cooking appliance, the vent grill is generally disposed on the upper side of a rear surface of the open-type cooking appliance. For example, an upper end of the exhaust duct may pass through the top plate and may be disposed on the rear surface side of the open-type cooking appliance, and the vent grill may be disposed on the upper side thereof, that is, an upper side of the rear surface of the top plate.

Meanwhile, a lower end of the exhaust duct may be connected to an upper surface of a cavity. An exhaust port may be formed to vertically pass through the upper surface of the cavity, and the exhaust duct may be connected to the interior of the cooking chamber through the exhaust port.

The heat source is provided in the inner space of the cooking chamber to heat the cooking chamber, and the gas burner, the electric heater, or the like may be used as the heat source. Among them, as in a broil burner or a broil heater, the heat source disposed above the cooking chamber is disposed adjacent to the exhaust port, and at least a part of the heat source is disposed below the exhaust port.

According to the above structure, water may flow into the exhaust duct through the exhaust hole of the vent grill. Further, the water introduced into the exhaust duct in this way may penetrate toward the heat source disposed below the exhaust duct.

In this way, the water penetrating toward the heat source may affect a normal ignition or operation of the heat source. For example, when the water penetrates into an electric connection part of the broil heater, the risk of an accident increases, and when the water penetrates into an ignitor of the broil burner, the risk of an ignition failure of the broil burner increases.

The first duct part <NUM> may include a plurality of sidewalls connecting the upper surface of the cavity <NUM> and the second duct part <NUM>. In the first duct part <NUM>, the plurality of sidewalls may be connected to each other while surrounding the first exhaust passage 411a in the front-rear direction and the left-right direction. For example, the first duct part <NUM> may be formed in a form in which four side walls are connected to form a quadrangular shape, in other words, in the form of a hexahedral shape including four sidewalls and having an open upper end and an open lower end.

In addition, the first duct part <NUM> may further include a coupling part <NUM>. The coupling part <NUM> is provided to couple the exhaust duct <NUM> and the cavity <NUM>. The coupling part <NUM> may protrude from a plurality of sidewalls to be coupled to one side surface of the cavity <NUM>, that is, the upper surface of the cavity <NUM>.

The coupling part <NUM> may protrude from a lower end of any one of the plurality of sidewalls in a direction parallel to one side surface of the cavity <NUM>. For example, the coupling part <NUM> may protrude from the lower end of each of the sidewalls, and the coupling part <NUM> may protrude from the lower end of the sidewall and, along with the sidewall, may form an "L" shape.

The second duct part <NUM> may be disposed between the first duct part <NUM> and the vent grill <NUM>. A second exhaust passage 415a may be formed inside the second duct part <NUM>. One side of the second exhaust passage 415a may be connected to the first exhaust passage 411a, and the other side of the second exhaust passage 415a may be open to the upper side of the exhaust port <NUM>.

In detail, a lower end of the second exhaust passage 415a may be connected to the first exhaust passage 411a, and an upper end of the second exhaust passage 415a may be open to the vent grill <NUM>. The first exhaust passage 411a and the second exhaust passage 415a are connected vertically, and the first exhaust passage 411a and the second exhaust passage 415a connected in this way may be collectively called exhaust passages 411a and 415a.

The second duct part <NUM> may be disposed behind the exhaust port <NUM>. That is, the second duct part <NUM> may be disposed behind a lower end of the first duct part <NUM>. The first duct part <NUM> connecting the second duct part <NUM> and the exhaust port <NUM> may extend from the exhaust port <NUM> toward the second duct part <NUM> in an upwardly inclined direction. That is, the first duct part <NUM> may be installed to be inclined in the rearward direction as the first duct part <NUM> goes to the upper side.

Accordingly, a rear sidewall <NUM> that is a sidewall located at the rearmost location among the plurality of sidewalls forming the first duct part <NUM> may be a sidewall located at the lowest location among the plurality of sidewalls.

The combustion gas flowing into a space between the ceiling surface of the cooking chamber <NUM> and the upper surface of the reflector <NUM> may be discharged to the outside of the cooking chamber <NUM> through the exhaust port <NUM> formed in the upper surface of the cavity <NUM>.

Further, the combustion gas discharged through the exhaust port <NUM> may flow upward through the exhaust passages 411a and 415b formed inside the exhaust duct <NUM> and may be discharged upward while passing through the vent grill <NUM> from the rear side of the cooking appliance <NUM>.

In addition, the broil burner <NUM> is provided with the ignition device <NUM>. The ignition device <NUM> serves to ignite the mixed gas discharged from the flame hole. As an example, the ignition device <NUM> may include a heating element having a ceramic-coated surface. The temperature of the mixed gas discharged from the flame hole of the broil burner <NUM> may be increased to an ignition temperature due to heat generated by the heating element of the ignition device <NUM>, and accordingly, the broil burner <NUM> is ignited.

The ignition device <NUM> may be disposed between the ceiling surface of the cooking chamber <NUM> and the reflector <NUM>. In more detail, the ignition device <NUM> is disposed below the exhaust port <NUM>. That is, the ignition device <NUM> may be disposed between the exhaust part <NUM> and the reflector <NUM>.

<FIG> is a perspective view illustrating a state in which an upper surface of the cavity and a blocking part illustrated in <FIG> are separated, <FIG> is a cross-sectional view taken along line "VIII-VIII" of <FIG>, and <FIG> is a cross-sectional view taken along line "IX-IX" of <FIG>.

Referring to <FIG>, a blocking part <NUM> may be provided inside the exhaust duct <NUM>. The blocking part <NUM> is provided to block at least a portion of a movement path of water flowing downward from the exhaust passages 411a and 415a inside the exhaust duct <NUM> toward the exhaust port <NUM>.

The blocking part <NUM> may be disposed between the other side of the exhaust passages 411a and 415a and the exhaust port <NUM>, that is, between an open upper end of the exhaust passages 411a and 415a and the exhaust port <NUM>. In the present embodiment, it is exemplified that the blocking part <NUM> is disposed inside the first duct part <NUM>. The blocking part <NUM> is disposed between the exhaust port <NUM> and the rear sidewall <NUM> that is a sidewall disposed on the rearmost side among the plurality of sidewalls forming the first duct part <NUM>. That is, the blocking part <NUM> is disposed between the exhaust port <NUM> and the rear sidewall <NUM> inside the first duct part <NUM>.

The blocking part <NUM> may be provided to protrude vertically from the one side surface of the cavity <NUM>. In the present embodiment, it is exemplified that the blocking part <NUM> is provided on the upper surface of the cavity <NUM> and is formed to protrude vertically.

The exhaust port <NUM> and the rear sidewall <NUM> may be connected to each other by the one side surface of the cavity <NUM>, that is, the upper surface of the cavity <NUM>. Further, the blocking part <NUM> may be formed to protrude upward from the upper surface of the cavity <NUM>. That is, the blocking part <NUM> may be formed integrally with the cavity <NUM>, and the blocking part <NUM> may be formed by a portion of the upper surface of the cavity <NUM>.

According to the present embodiment, the portion of the upper surface of the cavity <NUM> may be vertically perforated to form the exhaust port <NUM>. Further, the blocking part <NUM> may be formed in a form in which a portion of an edge of the cavity <NUM> surrounding the exhaust port <NUM> extends upward.

As an example, a protrusion wall part <NUM> may be provided in the edge of the cavity <NUM> surrounding the exhaust port <NUM>. The protrusion wall part <NUM> may be formed to protrude upward from the edge of the cavity <NUM> surrounding the exhaust port <NUM>.

The protrusion wall part <NUM> may be formed in the form of a wall surface externally surrounding the exhaust port <NUM> in a radial direction and may be formed in the form of a wall surface protruding upward from the exhaust port <NUM> and the edge of the cavity <NUM> surrounding the exhaust port <NUM>.

For example, the protrusion wall part <NUM> may be formed in the form of a burr that is generated when the upper surface of the cavity <NUM> is perforated from the bottom to the top to form the exhaust port <NUM>. A periphery of the exhaust port <NUM> may be surrounded by the protrusion wall part <NUM> surrounding a radially outer side of the exhaust port <NUM>.

Unlike the protrusion wall part <NUM>, the blocking part <NUM> may be formed in a form in which a portion of the edge of the cavity <NUM> surrounding the exhaust port <NUM> protrudes or extends upward. Although the protrusion wall part <NUM> is formed to completely surround the periphery of the exhaust port <NUM>, unlike the protrusion wall part <NUM>, the blocking part <NUM> does not completely surround the periphery of the exhaust port <NUM> but may be disposed only in the portion of the edge of the cavity <NUM> surrounding the exhaust port <NUM>.

Further, in the present embodiment, it is exemplified that the height of the blocking part <NUM> is greater than the height of the protrusion wall part <NUM>. That is, the blocking part <NUM> is formed to protrude upward further than the protrusion wall part <NUM>.

The blocking part <NUM> may be disposed between the other side of the exhaust passages 411a and 415a and the ignition device <NUM>. In the present embodiment, it is exemplified that the blocking part <NUM> is disposed between the second exhaust passage 415a and the exhaust port <NUM>. When viewed from the top, the ignition device <NUM> may be exposed to the upper portion of the exhaust port <NUM>, and the blocking part <NUM> may be disposed between the exhaust port <NUM> and the second exhaust passage 415a to block at least a portion of a passage between the second exhaust passage 415a and the exhaust port <NUM>. The blocking part <NUM> may block a movement path of water flowing downward from the exhaust passages 411a and 415a toward the ignition device <NUM>.

The blocking part <NUM> is disposed behind the ignition device <NUM>. The blocking part <NUM> may be disposed behind the exhaust port <NUM> and thus may be disposed behind at least a portion of the ignition device <NUM> exposed to the upper portion of the cavity <NUM>, that is, toward the exhaust passages 411a and 415a, through the exhaust port <NUM>. That is, the blocking part <NUM> may be disposed behind a portion of the ignition device <NUM> that is exposed to the upper portion of the cavity <NUM> through the exhaust port <NUM>.

As illustrated in <FIG> and <FIG>, the width of the blocking part <NUM> in the left-right direction may be set to be smaller than or equal to the width of the exhaust port <NUM> in the left-right direction. As an example, the width of the blocking part <NUM> in the left-right direction may be set to a value between the width of the ignition device <NUM> in the left-right direction and the width of the exhaust port <NUM> in the left-right direction. In more detail, the width of the blocking part <NUM> in the left-right direction is set to be greater than the width of the ignition device <NUM> in the left-right direction and may be smaller than the width of the exhaust port <NUM> in the left-right direction.

The blocking part <NUM> may be formed to protrude further than the ignition device <NUM> in the left-right direction. That is, when viewed from the top, both ends of the blocking part <NUM> in the left-right direction may be formed to protrude to the left side and the right side further than the ignition device <NUM>.

<FIG> is a view illustrating a water flow state inside an exhaust duct illustrated in <FIG>, and <FIG> is a view illustrating a water flow state inside an exhaust duct illustrated in <FIG>.

Hereinafter, an action and effect of the cooking appliance including the blocking part according to the present embodiment will be described with reference to <FIG> and <FIG>.

Referring to <FIG> and <FIG>, the blocking part <NUM> may be disposed behind the exhaust port <NUM>, disposed behind the ignition device <NUM>, formed to protrude further than the ignition device <NUM> in the left-right direction, and formed to protrude upward further than the protrusion wall part <NUM> surrounding the exhaust port <NUM>.

When water fills near the vent grill <NUM> due to water overflowing while the cooktop part <NUM> or the like is washed using water or cooking is performed in the cooktop part <NUM>, the water may flow into the exhaust duct <NUM> through the exhaust port <NUM> of the vent grill <NUM>. Further, in this way, the water flowing into the exhaust duct <NUM> may flow downward toward the exhaust port <NUM> through the exhaust passages 411a and 415a.

In this case, the water introduced into the exhaust duct <NUM> flows downward toward the exhaust port <NUM> mainly along the rear sidewall <NUM> inside the exhaust passages 411a and 415a. In this way, at least a portion of the flow of the downward flowing water is blocked by the blocking part <NUM> disposed between the second exhaust passage 415a and the exhaust port <NUM>.

As described above, the blocking part <NUM> is disposed behind the exhaust port <NUM> and provided to block a gap between the exhaust passages 411a and 415a and the ignition device <NUM>. The blocking part <NUM> blocks the flow of the water flowing downward toward the ignition device <NUM> inside the exhaust passages 411a and 415a main along the rear sidewall <NUM>.

Due to the action of the blocking part <NUM> as described above, the water flowing downward along the exhaust duct <NUM> is blocked by the blocking part <NUM>, does not flow downward toward a lower portion of the exhaust port <NUM>, and is spread to the periphery of the exhaust port <NUM>.

The periphery of the exhaust port <NUM> is surrounded by the protrusion wall part <NUM>. That is, the periphery of the exhaust port <NUM> is surrounded by the blocking part <NUM> and the protrusion wall part <NUM>, and a passage connecting the exhaust passages 411a and 415a and the exhaust port <NUM> is in a state of being blocked by the blocking part <NUM> and the protrusion wall part <NUM>.

The water, which is blocked by the blocking part <NUM>, does not flow downward to the lower portion of the exhaust port <NUM>, and is spread to the periphery of the exhaust port <NUM>, does not flow downward to the lower portion of the exhaust port <NUM> due to the protrusion wall part <NUM>, is gradually spread from the upper surface of the cavity <NUM>, and then is vaporized by heat of the cavity <NUM>.

That is, the water blocked by the blocking part <NUM> and spread to the periphery of the exhaust port <NUM> does not flow downward toward the ignition device <NUM> through the exhaust port <NUM> eventually and is removed by being vaporized by the heat of the cavity <NUM> heated by operating the heating part such as the broil burner <NUM> while being spread from the upper surface of the cavity <NUM>.

The blocking part <NUM> is formed to protrude upward further than the protrusion wall part <NUM>. Unlike the protrusion wall part <NUM> surrounding the periphery of the exhaust port <NUM>, the blocking part <NUM> is formed to have a width sufficient to block movement of the water to the ignition device <NUM> without surrounding the entire periphery of the exhaust port <NUM>. That is, the blocking part <NUM> is formed so as not to surround the entire periphery of the exhaust port <NUM>.

The blocking part <NUM> is a structure protruding from the inside of the exhaust passages 411a and 415a, and in this way, the structure protruding from the inside of the exhaust passages 411a and 415a may act as obstacles that hinder exhaust flow inside the exhaust passages 411a and 415a.

As the width of the blocking part <NUM> becomes greater, and as the height of the blocking part <NUM> becomes greater, penetration of the water into the ignition device <NUM> is blocked more effectively. However, as the width of the blocking part <NUM> becomes greater, and as the height of the blocking part <NUM> becomes greater, obstruction the exhaust flow made by the blocking part <NUM> inside the exhaust passages 411a and 415a inevitably becomes severe.

Thus, it is preferable that the width and the height of the blocking part <NUM> are set to a length at which the penetration of the water into the ignition device <NUM> may be effectively blocked even without hindering the exhaust flow inside the exhaust passages 411a and 415a.

In consideration of this point, the width of the blocking part <NUM> is formed to be slightly greater than the width of the ignition device <NUM>. As an example, the blocking part <NUM> may be formed in a width at which both sides of the blocking part <NUM> in the left-right direction may protrude from both sides of the ignition device <NUM> in the left-right direction by the range of about <NUM> to <NUM>. For example, when the width of the ignition device <NUM> is about <NUM>, the width of the blocking part <NUM> may be set in the range of about <NUM> to <NUM>.

Further, the height of the blocking part <NUM> may be set to be greater than the height of the protrusion wall part <NUM> and may be set to a height at which a sufficient space required for the flow of the combustion gas is secured between an upper end of the blocking part <NUM> and a ceiling surface of the exhaust duct <NUM>. As an example, the height of the blocking part <NUM> may be set in consideration of whether the penetration of the water into the ignition device <NUM> may be blocked and the concentration of carbon monoxide (CO) in the combustion gas discharged through the exhaust duct <NUM>. For example, the height of the blocking part <NUM> may be set to a height at which, when the set amount of the water flows into the exhaust duct <NUM>, the penetration of the water into the ignition device <NUM> may be blocked effectively, and the concentration of carbon monoxide (CO) in the combustion gas discharged through the exhaust duct <NUM> may be maintained at a set value or less.

In addition, in the present embodiment, it is exemplified that the blocking part <NUM> is formed to protrude vertically upward.

When the blocking part <NUM> is formed to be inclined forward toward the exhaust port <NUM>, a possibility that the water flowing downward from the inside of the exhaust duct <NUM> may not be blocked by the blocking part <NUM> and may overflow toward the exhaust port <NUM> over the blocking part <NUM> increases.

Further, when the blocking part <NUM> is formed to be inclined forward toward the exhaust port <NUM>, the blocking part <NUM> may become an obstacle that narrows a gap between the upper end of the blocking part <NUM> and the ceiling surface of the exhaust duct <NUM> to obstruct the exhaust flow.

Further, when the blocking part <NUM> is formed to be inclined forward toward the exhaust port <NUM>, in order to prevent the water from overflowing, the length of the blocking part <NUM> should be further increased. In this case, the blocking part <NUM> inevitably becomes an obstacle that more seriously obstructs the exhaust flow.

In contrast, when the blocking part <NUM> is formed to be inclined rearward toward the rear sidewall <NUM>, a possibility that the blocking part <NUM> hinders the exhaust flow can be significantly reduced. However, in this case, since the gap between the blocking part <NUM> and the exhaust duct <NUM> is narrowed, a possibility that the water cannot be properly blocked by the blocking part <NUM> increases.

In consideration of this point, in the present embodiment, it is exemplified that the blocking part <NUM> is formed to protrude vertically upward. In this way, since the blocking part <NUM> is formed to be protrude vertically upward, the penetration of the water into the ignition device <NUM> is effectively blocked, and despite the existence of the protrusion structure such as the blocking part <NUM>, the exhaust flow inside the exhaust duct <NUM> may be smoothly maintained.

Meanwhile, the protrusion wall part <NUM> surrounding the exhaust port <NUM> at a location adjacent to the blocking part <NUM>, along with the blocking part <NUM>, may serve to block the penetration of the water into the ignition device <NUM>.

The water, which is blocked by the blocking part <NUM>, does not flow downward to the lower portion of the exhaust port <NUM>, and is spread to the periphery of the exhaust port <NUM>, is gradually spread out from the upper surface of the cavity <NUM>. In this way, the water spread out from the upper surface of the cavity <NUM> may not flow downward to the lower portion of the exhaust port <NUM> due to the protrusion wall part <NUM> surrounding the exhaust port <NUM> and protruding upward and may be vaporized by the heat of the cavity <NUM> while staying on the upper surface of the cavity <NUM>. That is, the protrusion wall part <NUM> may serve to assist a function of the blocking part <NUM> in the vicinity of the blocking part <NUM>.

As described above, the protrusion wall part <NUM> may be formed in a form in which the portion of the edge of the cavity <NUM> surrounding the exhaust port <NUM> protrudes or extends upward. Accordingly, a wall surface by the protrusion wall part <NUM> instead of a sharp cut surface may be formed in an inner edge of the cavity <NUM> surrounding the exhaust port <NUM>. As a result, the risk that a worker is injured due to the sharp cut surface around the exhaust port <NUM> can be significantly reduced.

Further, as the protrusion structure such as the protrusion wall part <NUM> is formed on the upper surface of the cavity <NUM>, the upper surface of the cavity <NUM> may be flattened more easily, and accordingly, the flattening of the upper surface of the cavity <NUM> may be performed more effectively.

Further, the protrusion wall part <NUM> forming the protrusion structure on the upper surface of the cavity <NUM> may serve to guide an installation location of the exhaust duct <NUM>. For example, in a process of installing the exhaust duct <NUM>, an installation location of the exhaust duct <NUM> with respect to the cavity <NUM> may be guided to a location in which interference occurs between an inner surface of the first duct part <NUM> and the protrusion wall part <NUM>. Accordingly, the exhaust duct <NUM> may be installed more easily, more rapidly, and more accurately.

In the cooking appliance <NUM> according to the present embodiment as described above, a flow path of the water to the ignition device <NUM> through the exhaust port <NUM> from the exhaust passages 411a and 415a is blocked using the blocking part <NUM> protruding upward from the upper surface of the cavity <NUM> and disposed inside the exhaust duct <NUM> and behind the exhaust port <NUM>, and thus the water introduced through the exhaust duct <NUM> from the outside of the cooking appliance <NUM> may be effectively blocked from penetrating into the heat source.

Further, in the cooking appliance <NUM> of the present embodiment, since the flow path of the water to the ignition device <NUM> through the exhaust port <NUM> from the exhaust passages 411a and 415a is blocked by the blocking part <NUM>, the water introduced through the exhaust duct <NUM> from the outside of the cooking appliance <NUM> may be effectively blocked from being introduced into the ignition device <NUM>, and accordingly, occurrence of an ignition failure of the broil burner <NUM> may be effectively suppressed.

Meanwhile, the cooking appliance having the blocking part as configured above is merely an exemplary embodiment of the present disclosure, and various embodiments that may replace the embodiment may be present.

<FIG> is a view illustrating a configuration of a blocking part according to another embodiment of the present disclosure.

Hereinafter, a structure of a blocking part according to another embodiment of the present disclosure will be described with reference to <FIG>.

Here, the same reference numerals as in the drawings as illustrated above are designated by the same members having the same functions, and thus, a duplicated description thereof will be omitted.

Referring to <FIG>, a blocking part <NUM> according to another embodiment of the present disclosure may be formed in an exhaust duct <NUM> instead of the cavity <NUM>.

Accordingly, at least one of coupling parts <NUM> of the exhaust duct <NUM> may include a first protrusion part 414a and a second protrusion part 414b. In the present embodiment, it is exemplified that the coupling part <NUM> located at a lower end of a rear sidewall <NUM> includes the first protrusion part 414a and the second protrusion part 414b.

The first protrusion part 414a may extend rearward from the rear sidewall <NUM> to protrude rearward from the rear sidewall <NUM>. The first protrusion part 414a may form a flat surface parallel to the upper surface of the cavity <NUM> and may protrude rearward from the rear sidewall <NUM>.

The second protrusion part 414b is formed to extend from a lower end of the first protrusion part 414a. The second protrusion part 414b may be formed to extend from the lower end of the first protrusion part 414a to the front side of the rear sidewall <NUM>. For example, the second protrusion part 414b may be formed in a flat surface parallel to the first protrusion part 414a and a connection portion between the rear sidewall <NUM> and the first protrusion part 414a may be provided at a rear end of the rear sidewall <NUM>. Further, a connection portion between the first protrusion part 414a and the second protrusion part 414b may be provided at a front end of the rear sidewall <NUM>, and the second protrusion part 414b may be disposed below the first protrusion part 414a and disposed between the upper surface of the cavity <NUM> and the first protrusion part 414a. The second protrusion part 414b may be coupled to the cavity <NUM> while being in contact with the upper surface of the cavity <NUM>.

The blocking part200 may extend upward from a front end of the second protrusion part 414b. The blocking part <NUM> may be formed to protrude upward from one side surface of the cavity <NUM>, that is, the upper surface of the cavity <NUM>.

Like the blocking part <NUM> (see <FIG>) illustrated in the above-described embodiment, the blocking part <NUM> may be disposed inside the exhaust duct <NUM> and disposed between the rear sidewall <NUM> and the exhaust port <NUM>.

The blocking part <NUM> may be formed integrally with the exhaust duct <NUM>. That is, the blocking part <NUM> of the present embodiment may be formed integrally with the exhaust duct <NUM> by bending a lower end of the exhaust duct <NUM>.

Like the blocking part <NUM> as described in the above embodiment, in the blocking part <NUM>, the water introduced through the exhaust duct <NUM> from the outside of the cooking appliance <NUM> can be effectively blocked from penetrating into the heat source. Therefore, occurrence of an ignition failure of the broil burner <NUM> can be effectively suppressed, and of course, the blocking part <NUM> may be easily processed on the exhaust duct <NUM> only using a simple operation of simply changing the shape of the exhaust duct <NUM>.

That is, the blocking part <NUM> of the present embodiment can be easily manufactured only using a simple operation of adding a bending process to the exhaust duct <NUM> and can be easily applied to the cooking appliance <NUM> only using a simple operation of installing the exhaust duct <NUM>, in which the blocking part is processed, in the cooking appliance <NUM>.

In a cooking appliance of the present disclosure, a water flow path through which water flows from an exhaust passage through an exhaust port to an ignition device <NUM> is blocked using a blocking part that protrudes upward from an upper surface of a cavity and is disposed inside an exhaust duct and behind the exhaust port, and thus the penetration of the water introduced through the exhaust duct from the outside of the cooking appliance can be effectively blocked.

Further, according to the present disclosure, since the water flow path through which water flows from the exhaust passage through the exhaust port to the ignition device is blocked using the blocking part, the water introduced through the exhaust duct from the outside of the cooking appliance can be effectively blocked from being introduced into the ignition device, and thus the occurrence of an ignition failure of a heat source such as a boil burner can be effectively suppressed.
