Description

Cooking Appliance{COOKING APPLIANCE}

The present invention relates to a cooking appliance, and more specifically, to a cooking appliance provided with a door for opening and closing a cooking chamber.

A cooking appliance is a type of home appliance for cooking food and is installed in a kitchen space to cook food according to the user's intention. These cooking appliances can be classified in various ways depending on the heat source or type used and the type of fuel.

When classifying cooking appliances according to the type of space where plants are placed, cooking appliances can be classified into open cooking appliances and closed cooking appliances. Closed cooking appliances include ovens and microwave ovens. And open cooking appliances include cooktops, hobs, and griddles.

A closed cooking appliance is a cooking appliance that shields the space where food is located. These sealed cooking appliances can cook food by heating a shielded space.

Inside the closed cooking appliance, a cooking chamber is provided. The galley is a space where food is placed and a space where cooking appliances are shielded when cooking food. This galley is actually a space where food is cooked.

In closed cooking appliances, a rotatable door is provided to selectively open and close the cooking chamber. The door may be rotatably installed in the main body by a door hinge provided between the main body with a cooking chamber formed therein and the door. This door can selectively open and close the galley by rotating around the part that is coupled to the main body through the door hinge.

A heat source may be provided in the interior space of the cooking compartment that is opened and closed by the door. The heat source is provided to heat the cooking chamber. A gas burner or electric heater may be used as such a heat source.

In the upper part of the galley, an electronics room may be placed. The electrical components room may be equipped with electrical components necessary for the operation of the sealed cooking appliance. This battlefield room is formed as a space separated from the galley.

Inside the battlefield, a cooling fan may be provided to cool the battlefield. The cooling fan may be provided in the form of a centrifugal fan, such as a sirocco fan, and may be disposed biased toward the rear of the battlefield.

This cooling fan can cool the battlefield by sucking in external air and forcing it into the interior of the battlefield, and forcibly discharging the hot air inside the battlefield to the outside.

The main body may include a cavity and a front panel. The cavity forms the skeleton of the main body, and a cooking chamber may be formed inside the cavity. The front panel may be disposed in front of the cavity to form the front of the main body.

The electronics compartment may be placed at the top of the cavity. And the front of the battlefield can be shielded by the front panel. For example, at least a portion of the front panel may protrude above the cavity, and the upper area of the front panel disposed above the cavity may shield the front of the electrical equipment room.

In the front panel, an exhaust port may be provided. The exhaust port may be formed to penetrate the front panel in the front and rear directions. These exhaust ports can form a passage on the front panel for the air inside the battlefield to be discharged to the outside.

The exhaust port may be placed in the front of the electronics compartment, that is, in the upper area of the front panel. And on the front side of the exhaust port, a discharge passage may be formed. A control panel and a door may be disposed on the front side of the exhaust port, and a gap of a predetermined height may be formed between the control panel and the door disposed in the vertical direction. A discharge passage may be formed in the gap between the control panel and the door.

The exhaust port is exposed to the discharge passage side and may be connected to the discharge passage. Additionally, at least a portion of the exhaust port may be exposed to the front of the cooking appliance through this discharge passage. That is, at least a portion of the exhaust port may be exposed to the front through the gap between the control panel and the door.

Air introduced into the battlefield by a cooling fan inside the battlefield may be discharged to the outside of the battlefield through an exhaust port. And the air discharged through the exhaust port can be discharged to the front of the cooking appliance through the discharge passage between the control panel and the door.

Meanwhile, heat inside the cooking chamber generated during the cooking process may be transmitted to the outside of the door through the door. To shield this conductive heat, a plurality of glasses may be installed on the door.

For example, a front glass disposed on the outer side of the door and a rear glass disposed on the inner side of the door may be installed on the door, and a plurality of intermediate glasses may be installed between the front glass and the rear glass. Each intermediate glass may be provided with a radiation-reflective coating for heat shielding.

The heat inside the galley is transferred to the inner side of the door and then to the front glass through the middle glass inside the door. The conductive heat can be shielded by the radiant energy reflecting coating of the inner glass.

Additionally, a discharge hole may be provided at the top of the door. The discharge hole may be formed to penetrate the top of the door in a vertical direction. Through these discharge holes, hot air inside the door can be discharged into the discharge passage. At the same time, cold air may be sucked into the lower part of the door, where hot air has escaped.

That is, the door can be cooled by an air flow in which hot air inside the door is discharged through the top of the door and cold air is introduced into the inside of the door through the bottom of the door.

As described above, the discharge hole is disposed at the top of the door. In this way, the discharge hole disposed at the top of the door may be connected to the discharge passage. In other words, hot air discharged through the exhaust port and hot air discharged through the discharge hole may merge in the discharge passage.

The hot air discharged from the inside of the electrical room through the exhaust port may pass through the discharge passage and the upper area of the discharge hole before being discharged to the outside of the cooking appliance. In this process, the hot air flowing inside the discharge passage may flow back into the door through the discharge hole.

In other words, a phenomenon may occur where the air discharged from inside the electrical room cannot escape to the outside of the cooking appliance and flows back into the door through the exhaust hole. When this backflow occurs, cold air cannot properly flow into the inside of the door, making it difficult to cool the door smoothly.

Prior Document 1 (Korean Patent Publication No. 10-2015-0030016) discloses an oven.

As shown in FIGS. 28 and 29, the oven 1 disclosed in Prior Document 1 includes a casing 10 in which a cooking chamber 20 is provided, and a door 30 that opens and closes the open front of the cooking chamber 20. may include.

The cooking chamber 20 is a cooking space formed by a top plate 21, a bottom plate 22, both side plates 23, and a rear plate 24. Various parts constituting the oven 1 may be installed in the space between the outside of the cooking compartment 20 and the casing 10 (hereinafter referred to as the “electrical compartment”). A control panel 12 may be installed at the upper end of the casing 10 to control the operation of the oven 1.

A cooling fan 50 may be installed outside the top plate 21. The cooling fan 50 can introduce external air into the electrical equipment room through at least one opening installed on the rear panel 11 of the casing 10, etc., and then discharge the air introduced into the electrical equipment room back to the outside. .

A cooling passage 55 may be provided inside the battlefield. The cooling passage 55 forms a passage through which air sucked in by the cooling fan 50 flows toward the front of the oven 1.

A cooling discharge port 57 may be provided on the front side of the cooling passage 55. The air that has passed through the cooling passage 55 may be discharged to the upper part of the door 30 through the cooling discharge port 57. The cooling outlet 57 may be located rearward of the door 30.

A cooling guide 80 may be installed at the front end of the cooling discharge port 57. The cooling guide 80 may be provided in the form of a bent bracket to narrow the width of the cooling discharge port 57.

In the cooling discharge port 57 whose width is narrowed due to the cooling guide 80, a phenomenon in which the flow rate of air passing through the cooling discharge port 57 increases may occur. Accordingly, the air passing through the cooling discharge port 57 is discharged to the outside of the oven 1 at a high speed, while the pressure of the cooling discharge port 57 is lowered and the surrounding air gathers around the cooling discharge port 57. phenomenon may occur.

In this way, the air around the cooling outlet 57 gathers at the top of the door 30, thereby causing the air inside the door 30 to be discharged to the top of the door 30.

Prior Literature 1 states that, by inducing the discharge of air inside the door 30 induced in this way, the inflow of cold air into the inside of the door 30 is activated, and the inside of the door 30 of the air discharged through the cooling discharge port 57 is activated. It suggests the effect that backflow into the furnace can be suppressed.

However, Prior Document 1 has the following problems.

According to Prior Literature 1, the air passing through the cooling outlet 57 and the air discharged from the door 30 are discharged into a space located in front of the cooling outlet 57 and above the door 30.

That is, as the air discharged through the cooling discharge port 57 and the air discharged from inside the door 30 merge in one space, a vortex may be generated within the space. As vortices are generated in this way, the air that has passed through the cooling discharge port (57) and the air discharged from the door (30) may not be properly discharged to the outside of the oven (1), and the air in the space may not be discharged properly to the outside of the door (30). ) Internal reflux may occur.

In this case, it is difficult to properly cool the inside of the electrical equipment room and the inside of the door 30.

Additionally, in Prior Document 1, the cooling guide 80 also extends longitudinally along the lower part of the cooling discharge port 57, and the cooling guide 80 is fixed to the lower part of the cooling discharge port 57.

If the cooling outlet 57 is formed in a form divided into a plurality of pieces along the width direction of the oven 1, a plurality of cooling guides 80 to be fixed to the lower part of the cooling outlet 57 must also be provided.

In this case, a problem arises in that the assembly man-hours and number of parts required to install the cooling guide 80 are increased.

In addition, if the cooling discharge port 57 is provided in a continuous form along the width direction of the oven 1, that is, if only one long cooling discharge port 57 is formed in the oven 1, the strength of the front of the casing 1 increases accordingly. has no choice but to become weak.

On the other hand, when meat or food containing meat is heated and cooked using the above-mentioned sealed cooking device, oil such as fat or oil from the food floats inside the cooking chamber and adheres to the wall of the cooking chamber. It contaminates the inner wall of the kitchen.

The oil that adheres (adheres) to the wall of the cooking chamber in this way undergoes so-called polymerization (polymerization (reaction)) and sticks hard, making it difficult to clean (remove).

Among recently released cooking appliances, there are those equipped with a self-cleaning function that automatically removes contaminants such as oil as described above.

The self-cleaning function of cooking appliances is a function that automatically removes contaminants such as oil attached to the walls of the cooking chamber.

Self-cleaning in cooking appliances removes contaminants such as oil by burning them by heating the interior of the cooking chamber with a heat source such as a burner or heater to maintain the temperature inside the cooking chamber at a high temperature for a long time when contaminants such as oil adhere to the walls of the cooking chamber. This is mainly done using a thermal decomposition method called pyrolysis.

Prior document 1 also discloses a pyrolytic cleaning function that is the same or similar to this self-cleaning function. According to this, the control unit 38 of Prior Document 1 can perform a cleaning mode in which foreign substances are removed by thermal decomposition by increasing the temperature inside the cooking chamber 20. At this time, pyrolytic cleaning may be performed in the form of maintaining the internal temperature of the cooking chamber 20 at a high temperature for a long time using an electric heater 42 to burn and remove contaminants.

When the above-mentioned pyrolytic cleaning is performed, the inside of the cooking chamber 20 is maintained at a very high temperature. Therefore, to prevent safety accidents, the door of the cooking appliance must be tightly closed while the self-cleaning operation is in progress.

For this purpose, the oven 1 may be provided with a door locking device. The door lock device may be installed on the front of the oven 1 and may include a latch provided to lock the door 30 and a driving unit for operating the latch.

The driving unit may include a motor, and the driving unit and the latch may be connected by a link structure. The latch remains engaged with the door 30 while the door 30 must remain closed. When the door 30 no longer needs to remain closed, the latch may be released from the door 30.

The latch is installed on the front of the oven 1, rotates forward, and can protrude toward the front of the oven 1. This latch may rotate forward and protrude to be caught on the door 30, and may rotate backward and be separated from the door 30.

A locking groove may be provided at the top of the door 30, and the latch is inserted into the locking groove from the top of the locking groove and caught on the door 30, so that the door 30 can be locked by the door locking device.

The latch may be installed to be exposed to the front of the oven 1 so that the latch can protrude to the front of the oven 1 when necessary. Additionally, this latch may be placed higher than the door 30 so that it can enter and exit a locking groove provided at the top of the door 30.

In prior art document 1, if the latch is installed in the above position, the latch is positioned at the front of the oven 1 not only when the door 30 opens the cooking chamber 20 but also when the door 30 closes the cooking chamber 20. is exposed as

That is, the latch disposed above the door 30 is exposed to the front of the oven 1 through the gap between the door 30 and the control panel, which may deteriorate the aesthetics of the oven 1.

And the air guide 300 can be stably fixed to the lower side of the control panel 200 by being coupled to the plurality of cover protrusions 210 and 220, respectively.

Referring to Figures 3 and 13 to 15, the air guide 300 may include a first guide part 310 and a second guide part 320.

The first guide part 310 and the second guide part 320 are parts that occupy most of the area of the air guide 300 and can form most of the exterior of the air guide 300.

The first guide portion 310 is a portion disposed on the front side of the air guide 300, and may be disposed on the front side of the second guide portion 320. This first guide portion 310 is a control panel It is disposed between 200 and the door 150 to divide the space between the control panel 200 and the door 150 upward and downward.

This first guide unit 310 can divide the space between the control panel 200 and the door 150 into an upper first space (S1) and a lower second space (S2).

The second guide portion 320 is a portion disposed on the rear side of the air guide 300 and may be disposed rearward than the first guide portion 310. This second guide part 320 may be connected to the first guide part 310 at the rear side of the first guide part 310.

The second guide part 320 may be arranged in the front space S, but may be arranged in a space surrounded by the first guide part 310, the exhaust port 122, and the door exhaust port 152. This second guide unit 320, together with the first guide unit 310, divides the space between the control panel 200 and the door 150 into an upper first space (S1) and a lower second space (S2). It can be divided into

The second guide part 320 may extend from the first guide part 310 toward the rear side. This second guide part 320 moves in a direction from the first guide part 310 toward the main body 100, more specifically, the front panel 120, and from the first guide part 310 towards the door 150. It can extend in a direction between facing directions.

In other words, the second guide part 320 may be formed to be inclined downwardly and backward from the first guide part 310.

In this embodiment, the door exhaust port 152 may be placed at a lower position than the exhaust port 122. In the vertical direction, at least a portion of the second guide portion 320 may be disposed between the door exhaust port 152 and the exhaust port 122.

Additionally, in the front-back direction, at least a portion of the second guide portion 320 may be disposed between the door exhaust port 152 and the exhaust port 122.

This second guide part 320 may be arranged such that at least a portion of the second guide part 320 blocks the space between the exhaust port 122 and the door exhaust port 152. That is, the second guide unit 320 may be disposed to block the path through which the air discharged from the exhaust port 122 flows and the path through which the air discharged from the door exhaust port 152 flows.

The first guide part 310 may be formed in a planar shape parallel to the bottom surface of the control panel 200 or the top surface of the door 150. At this time, the first guide part 310 may be formed in a shape including a plane perpendicular to the vertical axis.

The second guide part 320 may be provided to be connected to the first guide part 310 in the front-to-back direction. This second guide part 320 may be formed to extend rearward from the rear end of the first guide part 310.

As an example, the second guide part 320 may be formed in the shape of an inclined surface extending rearward from the rear end of the first guide part 310. At this time, the second guide portion 320 may be formed in the shape of an inclined surface extending downward toward the rear.

At least a portion of the second guide portion 320 formed in this way may be disposed between the door exhaust port 152 and the exhaust port 122. That is, in the vertical and forward directions, at least a portion of the second guide part 320 may be disposed between the door exhaust port 152 and the exhaust port 122.

The second guide part 320 may be disposed on the upper side of the door 150 and on the upper side of the rear half 150b.

According to this embodiment, the first guide part 310 and the second guide part 320 are disposed on the upper side of the door 150. Among these, the first guide part 310 may be disposed on the upper side of the front half 150a. And the second guide part 320 may be disposed on the upper side of the latter half (150b).

The first guide portion 310 may form a plane parallel to the upper surface of the front half 150a. And the second guide portion 320 may form an inclined surface parallel to the rear half 150b of the door 150.

Accordingly, the first guide part 310 and the second guide part 320 can be disposed between the door 150 and the control panel 200 while maintaining a predetermined distance from the door 150.

And the second guide part 320, which forms an inclined surface as described above, blocks the space between the door exhaust port 152 and the exhaust port 122, and controls the flow of air discharged from the exhaust port 122 with the air guide 300. It may serve to guide the flow of air discharged from the door exhaust port 152 toward the passage formed between the panels 200 and the passage formed between the door 150 and the air guide 300.

In addition, the air guide 300 may further include an extension portion 315. The extension portion 315 may be disposed on both sides of the first guide portion 310 in the lateral direction. This extension part 315 may be formed to protrude laterally from the first guide part 310.

The extension portion 315 is not a portion coupled to the cover protrusions 210 and 220. Accordingly, the length of the extension portion 315 may be set shorter than the total length of the first guide portion 310 and the air guide 300.

Since the extension part 315 is formed in a shape in which the length of the extension part 315 is shorter than the total length of the air guide 300, the overall size and weight of the air guide 300 may not be unnecessarily increased.

The extension portion 315 may be disposed biased toward the front side of the air guide 300. Preferably, the first guide part 310 and the extension part 315 are laterally connected so that the front end of the extension part 315 and the front end of the first guide part 310 are disposed on the same line. You can.

In this embodiment, the extension part 315 is illustrated as protruding from the first guide part 310 with the same length as the first guide part 310.

Accordingly, although the length of the extension part 315 of the first guide part 310 is set shorter than the total length of the air guide 300, the appearance of the air guide 300 seen from the front is formed in a smoothly continuous form. It becomes possible.

In addition, the extension portion 315 may be disposed in front of the protruding surface portion 123, as shown in FIG. 7 . As described above, the protruding surface portion 123 is formed to protrude forward from the lateral end of the front panel 120.

The extension portion 315 disposed in front of the protruding surface portion 123 is formed to have a shorter length than the first guide portion 310 as described above and is disposed biased toward the front side on the air guide 300, so that the protruding surface portion ( 123) can be avoided.

That is, the extension portion 315 formed in the above shape has the effect of maintaining the aesthetics of the air guide 300 visible from the front while avoiding interference with the protruding surface portion 123, and the size and weight of the air guide 300. It can also provide the effect of preventing this from increasing unnecessarily.

[Air guide arrangement structure considering the front appearance of the cooking appliance]

FIG. 16 is a front view showing a portion of the front of the cooking appliance with the air guide removed, and FIG. 17 is an enlarged view of a portion of the front of the cooking appliance shown in FIG. 16. Additionally, FIG. 18 is a front view showing a portion of the front of a cooking appliance according to an embodiment of the present invention, and FIG. 19 is an enlarged view showing a portion of the front of the cooking appliance shown in FIG. 18.

Referring to FIGS. 16 and 17, when the air guide is excluded from the cooking appliance, various airflows of the cooking appliance are exposed through the gap between the control panel 200 and the door 150 (hereinafter referred to as the “front gap”). Parts may be exposed to the front of the cooking appliance.

As an example, a portion of the front panel 120 may be exposed to the front of the cooking appliance through the front gap. Specifically, a plurality of exhaust ports 122 provided in the control panel 200 may be exposed to the front of the cooking appliance through the front gap. Additionally, the partition walls 121 disposed between the exhaust ports 122 may be exposed to the front of the cooking appliance through the front gap.

In addition, among the various electrical components arranged in the electrical equipment room 103, a portion of the parts disposed behind the exhaust port 122 may be exposed to the front of the cooking appliance through the front gap.

Additionally, at least a portion of the door lock may be exposed to the front of the cooking appliance through the front gap. For example, most of the latch 140 may be exposed to the front of the cooking appliance through the front gap. Additionally, a portion of the driving unit 145 along with the latch 140 may be exposed to the front of the cooking appliance through the front gap.

When the above items are exposed to the front of the cooking appliance, they may have a negative impact on the front appearance of the cooking appliance. That is, the shapes formed on the front panel 120, such as the exhaust port 122 and the partition wall 121, the complex-shaped structures such as the latch 140, and the electrical components exposed through the exhaust port 122, add to the aesthetics of the front of the cooking appliance. It can be a damaging factor.

In order to reduce the influence they have on the front aesthetics of the cooking appliance, in this embodiment, as shown in FIGS. 18 and 19, an air guide 300 may be provided in the cooking appliance.

The air guide 300 may be placed in the front gap. The air guide 300 is disposed between the control panel 200 and the door 150, and is provided to cover parts of the front panel 120, latch 140, and electrical components from the front.

This air guide 300 covers a portion of the front gap between the control panel 200 and the door 150, and thus the front panel 120 and the latch 140, which were exposed to the front of the cooking appliance through the front gap. ), some parts of the electrical components, etc. may be obscured by the air guide 300.

As the thickness of the air guide 300 increases, the area covered by the air guide 300 may expand. As the area covered by the air guide 300 is expanded, the aesthetics of the front of the cooking appliance may be improved, but exhaustion to the front of the cooking appliance through the front space (S; see FIG. 3) becomes more difficult.

Conversely, as the thickness of the air guide 300 becomes thinner, the area covered by the air guide 300 may decrease. As the area covered by the air guide 300 decreases, the effect of improving the front aesthetics of the cooking appliance decreases, but instead, exhaust to the front of the cooking appliance through the front space S can be achieved more smoothly.

Considering this, it is preferable that the thickness of the air guide 300 is set to the thickest thickness within a range that ensures smooth exhaustion to the front of the cooking appliance through the front space (S).

When the thickness of the air guide 300 is set to satisfy these conditions, the exhaust efficiency through the front gap can be maintained at a certain level or higher while effectively improving the front aesthetics of the cooking appliance.

According to this embodiment, some of the areas exposed to the front of the cooking appliance through the front gap are covered by the air guide 300, thereby improving the aesthetics of the front of the cooking appliance.

As an example, the air guide 300 may be placed in the front gap, and the first guide part 310 may be positioned in the vertical center of the front gap. That is, the air guide 300 is disposed between the door 150 that closes the galley and the control panel 200, and the vertical distance between the first guide part 310 and the control panel 200 and the first guide part ( It may be placed at a position where the vertical distance between 310) and the door 150 is set to be the same (hereinafter referred to as “center position”).

Accordingly, the air guide 300 can form a structure that allows the first guide part 310 to cover the front gap at the vertical center of the front gap, that is, at the central position.

This air guide 300 allows the upper area of the front gap and the lower area of the front gap to be symmetrical around the first guide part 310, thereby making the front shape of the cooking appliance appear more stable. This can contribute to improving the overall aesthetics of the cooking appliance.

Additionally, the air guide 300 in this embodiment can cover the lower area of the front gap through the second guide part 320 disposed on the rear side of the first guide part 310. At this time, since the second guide part 320 is disposed on the rear side of the first guide part 310, it is not as noticeable as the first guide part 310 when viewed from the front.

That is, the second guide part 320 can cover the lower area of the front gap in a less conspicuous position compared to the first guide part 310.

The air guide 300 having this second guide part 320 covers the front gap so that the upper area of the front gap and the lower area of the front gap are symmetrical around the first guide unit 310, and The lower area of the front gap can be further covered by using the second guide part 320, which is less noticeable than the first guide part 310.

The air guide 300 of this embodiment can effectively improve the front aesthetics of the cooking appliance while making the front shape of the cooking appliance appear more stable.

Meanwhile, as described above, the air guide 300 may be coupled to the control panel 200 by the cover protrusions 210 and 220.

As an example, the cover protrusions 210 and 220 may include an outer cover protrusion 210.

The outer cover protrusion 210 may be provided in a form that protrudes downward from the bottom of the control panel 200. This outer cover protrusion 210 may be coupled to the air guide 300 at the lower part of the control panel 200. By coupling between the outer cover protrusion 210 and the air guide 300, the air guide 300 can be coupled to the control panel 200 while being spaced a predetermined distance from the bottom of the control panel 200.

Preferably, when the outer cover protrusion 210 is coupled to the air guide 300, the air guide 300 may be disposed at a central position.

The outer cover protrusion 210 may be disposed in a position to cover at least a portion of the latch 140 from the front side. For example, the outer cover protrusion 210 protrudes downward from the bottom of the control panel 200, and may protrude from the vertical upper side of the latch 140.

At least a portion of the latch 140 is covered by the outer cover protrusion 210 arranged in this way. Accordingly, when viewed from the front, at least a portion of the latch 140 is obscured by the outer cover protrusion 210 and is not visible.

As an example, the outer cover protrusion 210 may be formed to protrude from the bottom of the control panel 200 to the central position. Additionally, the width of the outer cover protrusion 210 may be set to be greater than or equal to the width of the latch 140. This outer cover protrusion 210 may cover the upper half of the latch 140 exposed through the front gap from the front. The lower half of the latch 140 may be exposed to the lower side of the air guide 300.

According to this embodiment, the side shape of the latch 140 may be set to approximately an “L” shape. This latch 140 may be formed so that its upper end protrudes forward. Therefore, when viewed from the front, the upper half of the latch 140 has a more complicated shape than the lower half of the latch 140.

The outer cover protrusion 210 is formed to protrude from the control panel 200 by the length necessary to be coupled with the air guide 300, while protruding from the control panel 200 by the length necessary to cover the upper half of the latch 140. can be formed.

That is, the outer cover protrusion 210 only protrudes long enough to cover the upper half of the latch 140 while fixing the air guide 300 in the central position, but does not protrude longer.

If the outer cover protrusion 210 protrudes longer, the outer cover protrusion 210 may cover more of the latch 140, but the coupling structure of the outer cover protrusion 210 and the air guide 300 is complicated. Problems may arise where the combination itself becomes difficult. Additionally, unnecessarily protruding structures may cause the problem of deteriorating the overall aesthetics of the cooking appliance.

Considering this, in this embodiment, the outer cover protrusion 210 does not protrude unnecessarily long, but protrudes long enough to cover the upper half of the latch 140 while fixing the air guide 300 in the central position.

This outer cover protrusion 210 preferentially covers the upper half of the latch 140, which is a part that can greatly affect the front aesthetics of the cooking appliance, and also arranges the air guide 300 in the central position. , can contribute to effectively improving the overall aesthetics of cooking appliances.

As another example, the air guide 300 may be disposed in the front gap, but may be disposed in a position more inclined downward from the vertical center of the front gap.

Considering that the user's eye level is generally higher than the height of the air guide 300 placed between the door 150 and the control panel 200, the air guide 300 must be placed in the above position to allow the user to use air. The guide 300 can be better identified.

In addition, the aesthetics provided by the air guide 300 can be expressed more effectively when the air guide 300 is placed in a position where the air guide 300 can be clearly seen from the outside of the cooking appliance.

In other words, by arranging the air guide 300 in a position more inclined toward the bottom from the vertical center of the front gap, aesthetics can be effectively created.

In addition, when the air guide 300 is disposed at the above position, the vertical length of the cover projections 210 and 220, especially the outer cover projection 210, becomes longer.

When the length of the outer cover protrusion 200 is increased in this way, the outer cover protrusion 210 can cover the latch 140 and cover a wider area than the upper half of the latch 140. In this way, more of the latch 140 is covered by the outer cover protrusion 210, so that the front aesthetics of the cooking appliance can be more effectively improved.

Meanwhile, in this embodiment, the latch 140 is illustrated as being disposed on one side of the main body 100 in the lateral direction. For example, in a cooking appliance, one latch 140 may be disposed at a position biased toward one side of the main body 100. At this time, the latch 140 may be disposed in a position that is more biased to one side of the main body 100 in the lateral direction than the exhaust port 122.

According to this embodiment, a pair of outer cover protrusions 210 may be disposed between the control panel 200 and the air guide 300. The pair of outer cover protrusions 210 may be arranged symmetrically about the lateral center of the cooking compartment, that is, about the lateral center of the main body 100. Alternatively, the pair of outer cover protrusions 210 may be expressed as being symmetrically disposed about the lateral center of the control panel 200.

One of the pair of outer cover protrusions 210 may be disposed in front of the latch 140 and cover the upper half of the latch 140 from the front. The other one of the pair of outer cover protrusions 210 is not disposed in front of the latch 140.

However, by arranging the pair of outer cover protrusions 210 symmetrically as described above, the shapes of the cover protrusions 210 and 220 and the air guide 300 exposed through the front gap can appear more balanced.

The cover protrusions 210 and 220 may include an inner cover protrusion 220.

The inner cover protrusion 220 may be provided in a form that protrudes downward from the bottom of the control panel 200. This inner cover protrusion 220 may be coupled to the air guide 300 at the lower part of the control panel 200. By coupling between the inner cover protrusion 220 and the air guide 300, the air guide 300 can be coupled to the control panel 200 while being spaced a predetermined distance from the bottom of the control panel 200.

Preferably, when the inner cover protrusion 220 is coupled to the air guide 300, the air guide 300 may be placed at a central position.

The inner cover protrusion 220 may be disposed in a position where at least a portion of the inner cover protrusion 220 can cover at least a portion of the partition wall 121 from the front side. For example, the inner cover protrusion 220 protrudes downward from the bottom of the control panel 200, and may protrude from the vertical upper side of the partition wall 121.

At least a portion of the partition wall 121 is covered by the inner cover protrusion 220 arranged in this way. Accordingly, when viewed from the front, at least a portion of the partition wall 121 is obscured by the inner cover protrusion 220 and is not visible.

The inner cover protrusion 220 arranged as described above may be disposed between a pair of outer cover protrusions 210. For example, among the plurality of cover protrusions 210 and 220 arranged in the lateral direction, the outer cover protrusion 210 may be disposed on the outermost side in the lateral direction, and the inner cover protrusion 220 may be disposed between them.

By the inner cover protrusion 220 and the outer cover protrusion 210 provided in this way, the air guide 300 is coupled to the cover protrusions 210 and 220 at multiple points in the lateral direction and is stably fixed to the lower part of the control panel 200. You can.

That is, the inner cover protrusion 220 can contribute to stably fixing the air guide 300 by increasing the coupling point between the control panel 200 and the air guide 300.

In addition, the inner cover protrusion 220 is disposed in a position to cover the partition wall 121 from the front, thereby preventing the number of vertical structures exposed through the front gap from increasing.

That is, the inner cover protrusion 220 may be arranged in such a way that the inner cover protrusion 220 covers the partition wall 121, which is a vertical structure that is exposed anyway through the front gap. As a result, it may appear that the number of longitudinal structures exposed through the anterior gap has not increased.

As a result, it is possible to effectively prevent the front aesthetics of the cooking appliance from being deteriorated due to the vertical structure exposed through the front gap.

Additionally, the inner cover protrusion 220 arranged as described above can be placed in a position avoiding the exhaust port 122. The exhaust port 122 forms a passage necessary for air from the battlefield room 103 (see FIG. 3) to be discharged into the front space S.

The air introduced into the electrical equipment room 103 by the fan module 170 (see FIG. 3) exchanges heat within the electrical equipment room 103 and can cool electrical components, etc. The air heat-exchanged inside the electrical equipment compartment 103 may be discharged at a high temperature into the front space S through the exhaust port 122.

Assuming that the inner cover protrusion 220 is made of a plastic material, if the inner cover protrusion 220 is constantly exposed to high temperature air discharged through the exhaust port 122, thermal deformation of the inner cover protrusion 220 occurs. The risk of becoming infected may increase.

For example, if the inner cover protrusion 220 is disposed in front of the exhaust port 122 rather than in front of the partition 121, thermal deformation of the inner cover protrusion 220 may occur due to the high temperature air discharged through the exhaust port 122. It can happen.

Considering this, in this embodiment, the inner cover protrusion 220 is disposed at a position avoiding the exhaust port 122, that is, in front of the partition wall 121 rather than in front of the exhaust port 122.

As a result, thermal deformation of the inner cover protrusion 220 can be effectively prevented, and air can be discharged through the exhaust port 122 smoothly without being hindered by the inner cover protrusion 220.

That is, the inner cover protrusion 220 of the present embodiment is disposed in a position to cover the exhaust port 122 from the front, so there is a risk of thermal deformation of the inner cover protrusion 220 without impeding the discharge of air through the exhaust port 122. It can be placed in a position that lowers and improves the front aesthetics of the cooking appliance.

In summary, the effects provided by the air guide 300 arranged as above and the cover protrusions 210 and 220 for fixing it are as follows.

First, the aesthetics of the front of the cooking appliance can be improved by covering some of the structures exposed through the front gap by the air guide 300, which laterally crosses the front gap and provides a structure that covers the front gap.

The air guide 300 covers part of other structures at the rear and focuses the gaze looking at the front gap on the air guide 300, creating an optical illusion that only the air guide 300 exists in the front gap. ensure that it is provided.

In addition, the air guide 300 forms a structure that covers the front gap at the center of the front gap, so that the upper area of the front gap and the lower area of the front gap are symmetrical, and the front shape of the cooking appliance is more stable. It can be displayed as .

Through this, the air guide 300 can contribute to effectively improving the front aesthetics of the cooking appliance.

Second, by covering at least a portion of a large and complex structure, such as the latch 140, by the outer cover protrusion 210, the front aesthetics of the cooking appliance can be more effectively improved.

According to this embodiment, the upper half of the latch 140, which is a part that can greatly affect the front appearance of the cooking appliance, may be covered by the outer cover protrusion 210 provided for fixing the air guide 300. .

That is, the arrangement position of the outer cover protrusion 210 provided for fixing the air guide 300 is appropriately set in front of the latch 140, thereby stably fixing the air guide 300 and improving the front aesthetics of the cooking appliance. It can be accomplished.

Third, the inner cover protrusion 220 is disposed in a position to cover the partition wall 121 dividing the exhaust port 122 between the exhaust port 122 from the front, so that the inner cover protrusion 220 does not interfere with the discharge of air through the exhaust port 122. It can provide the effect of lowering the risk of thermal deformation of the cover protrusion 220 and the effect of improving the front aesthetics of the cooking appliance.

[Coupling structure between control panel and air guide]

Figure 20 is a cross-sectional perspective view showing the coupling structure between the air guide and the control panel, Figure 21 is a cross-sectional exploded perspective view showing the separated state of the air guide and control panel shown in Figure 20, and Figure 22 is the air guide shown in Figure 21. This is a cross-sectional exploded perspective view showing another example of a guide.

Referring to Figures 13 and 17 to 21, cover protrusions 210 and 220 may be included in the front panel 120. As an example, the cover protrusions 210 and 220 may be formed integrally with the front panel 120. More specifically, the cover protrusions 210 and 220 may be formed integrally with the bottom of the front panel 120.

In this embodiment, the bottom of the front panel 120 and the cover protrusions 210 and 220 are illustrated as being made of plastic material. Since the cover projections 210 and 220 are made of plastic and are formed integrally with the bottom of the front panel 120, not only can the cost required for adding the cover projections 210 and 220 be reduced, but the cover projections 210 and 220 are made of metal. Compared to the case in which they are formed, the weight of the cover protrusions 210 and 220 can be significantly reduced.

The air guide 300 may be made of a metal material. As an example, the air guide 300 may be made of a metal material that has excellent heat resistance and a metal-specific luster. This air guide 300 is not easily deformed by high temperature heat, is not easily damaged by impact, and can contribute to improving the aesthetics of the cooking appliance through metallic luster.

Considering that the air guide 300 is placed in a path where high-temperature air is discharged, that it is placed in a prominent position on the front of the cooking appliance, and that it is placed in a location where frequent contact with the user may occur, , In this embodiment, the air guide 300 is made of a metal material.

The cover protrusions 210 and 220 may be coupled to the first guide portion 310. A hollow is formed in each of the cover protrusions 210 and 220, and a fastening hole in communication with the first guide portion 310 may be formed to penetrate in the vertical direction. These cover protrusions 210 and 220 and the first guide portion 310 may be coupled by a fastening member 305 such as a screw.

As another example, as shown in FIG. 22, a cover protrusion 330 may be included in the air guide (300a). This cover protrusion 330 may be formed to protrude upward from the first guide portion 310. As an example, the cover protrusion 330 may be formed integrally with the air guide (300a).

In this embodiment, the combination of the cover protrusion 330 and the air guide 300a is illustrated as being formed of a metal material. As an example, the combination of the cover protrusion 330 and the air guide 300 may be made of a metal material that has excellent heat resistance and a metal-specific luster.

As the cover protrusion 330 is made of a metal material and is formed integrally with the air guide 300a, the cover protrusion 330 may not be easily deformed even under high temperature heat.

In addition, both the cover protrusion 330 and the air guide 300a, which account for most of the structures exposed through the front gap, are made of a metal material with a metallic luster, so that the aesthetics of the cooking appliance can be more effectively improved.

[Air guide arrangement structure considering exhaust flow]

FIG. 23 is a cross-sectional view showing the air flow inside the cooking appliance according to an embodiment of the present invention, and FIG. 24 is an enlarged view showing a portion of the cooking appliance shown in FIG. 23. In addition, FIG. 25 is an enlarged view of a portion of the cooking appliance shown in FIG. 24, and FIG. 26 is an enlarged view of the “ⅩⅩⅥ” portion of FIG. 25.

Referring to FIGS. 23 to 26, by operating the fan module 170, external air may be introduced into the electrical equipment compartment 103 from the rear side of the cooking appliance. In this way, the air introduced into the electrical equipment room 103 can move forward inside the electrical equipment room 103 and cool the electrical components inside the electrical equipment room 103.

To be more specific, external air may flow into the inside of the cooking appliance through the lower part of the main body 100. The outside air flowing in through the lower part of the main body 100 passes through the rear space of the cooking appliance where the convection unit 160, etc. is placed, and various parts disposed in the rear space of the cooking appliance, such as the convection unit 160. ) can be cooled.

In this way, the air that passes through the rear space of the cooking appliance and moves upward can move toward the electrical appliance room 103 through the space covered by the electrical appliance cover 133 between the rear space of the cooking appliance and the electrical appliance room 103. there is.

Air moving inside the electrical equipment room 103 may be sucked in by the fan module 170 and introduced into the duct 133. The air flowing into the duct 133 moves forward inside the duct 133 and can cool the electrical components inside the electrical equipment room 103.

As described above, the air moving forward inside the electrical equipment compartment 103 may be discharged through the exhaust port 122 to the front of the electrical equipment compartment 103, that is, to the front space (S).

Additionally, the air inside the door 150 heated by the heat transferred from the cooking chamber 101 during the cooking process may be discharged to the outside of the door 150 through the door exhaust port 152 provided at the top of the door 150.

As the hot air inside the door 150 is discharged, the outside air at the front lower side of the cooking appliance may flow into the inside of the door 150 through the air flow hole provided at the bottom of the door 150 and rise. In this process, the heated door 150 may be cooled by the heat transferred from the cooking chamber 101 to the door 150.

Additionally, the air that cools the door 150 and rises inside the door 150 may be discharged into the front space (S) through the door exhaust port 152. That is, the air discharged through the exhaust port 122 and the air discharged through the door exhaust port 152 may join in the front space S and be discharged to the front of the cooking appliance.

According to this embodiment, the front space (S) is a space surrounded by the door 150, the front panel 120, and the control panel 200, and the air guide 300 can be placed in this front space (S). .

The exhaust port 122 may communicate with the front space (S) at the rear side of the front space (S), and the door exhaust port 152 may communicate with the front space (S) at the lower side of the front space (S). And the front space (S) may be open toward the front of the cooking appliance.

The door exhaust port 152 may be disposed between the air guide 300 and the front panel 120. Specifically, the door exhaust port 152 may be disposed in front of the exhaust port 122. That is, in the front-back direction, the door exhaust port 152 may be disposed between the air guide 300 and the exhaust port 122.

Additionally, the door exhaust port 152 may be disposed below the air guide 300 and the exhaust port 122. In addition, the door exhaust port 152 may be provided at the top of the door 150, but may be provided on the latter half (150b).

Accordingly, the door exhaust port 152 is disposed at a position biased toward the rear on the door 150, and may be disposed on the lower side rather than the top of the door 150 formed by the front half 150a.

Looking at the arrangement relationship between the exhaust port 122, the door exhaust port 152, and the air guide 300, the door exhaust port 152 is placed at a position on the door 150 that is closest to the exhaust port 122 in the front and rear directions. .

If the door exhaust port 152 is disposed in the front half (150a) rather than the rear half (150b) of the door 150, hot air discharged through the exhaust port 122 flows into the inside of the door 150 through the door exhaust port 152. The likelihood of reflux increases.

The air discharged through the exhaust port 122 gradually spreads in the front space (S) and moves forward in the front space (S). That is, the air discharged through the exhaust port 122 spreads not only in the left and right directions but also in the up and down directions within the front space (S) and moves forward.

Therefore, the closer the door exhaust port 152 is located to the front within the front space S, the more likely it is that the air discharged through the exhaust port 122 will flow into the door exhaust port 152.

In this way, if the hot air discharged through the exhaust port 122 flows back into the door 150 through the door exhaust port 152, the door 150 cannot be cooled smoothly and flows into the front space (S). It becomes difficult for the heat to be discharged smoothly to the outside of the cooking appliance.

Taking this into consideration, in this embodiment, the door exhaust port 152 is disposed in the latter half (150b) of the door 150, and is thus located at a position on the door 150 that is closest to the exhaust port 122 in the front and rear directions. A door exhaust port 152 may be disposed.

As a result, the door exhaust port 152 can be placed in a position that can deviate from the flow area of the air discharged through the exhaust port 122 as much as possible among the selectable forward and backward positions within the door 150.

Additionally, according to this embodiment, the door exhaust port 152 is disposed in the rear half 150b, so that it can be disposed lower than the uppermost end of the door 150 formed by the front half 150a. That is, the door exhaust port 152 may be disposed further downward from the flow area of air discharged through the exhaust port 122.

As a result, the door exhaust port 152 can be placed in a position that can deviate from the flow area of the air discharged through the exhaust port 122 as much as possible. The door exhaust port 152 arranged in this way can contribute to effectively suppressing the phenomenon of hot air discharged into the front space S flowing back into the door 150.

Additionally, the door exhaust port 152 may not be disposed on the vertical lower side of the air guide 300, but may be disposed rearward than the air guide 300. Accordingly, the flow of air discharged from the door exhaust port 152 can flow smoothly toward the front space S without being interrupted by the air guide 300.

According to this embodiment, the door exhaust port 152 may be disposed between the air guide 300 and the front panel 120. That is, the air guide 300 may be disposed in front of the exhaust port 122 and the door exhaust port 152. This air guide 300 may be placed at a position biased toward the front within the front space (S).

The air guide 300 arranged in this way can guide the flow of air discharged from the exhaust port 122 and the door exhaust port 152 to the front space (S) from the front side of the front space (S).

For example, the air discharged from the exhaust port 122 and the door exhaust port 152 into the front space (S) may merge in the front space (S) and be discharged to the front of the cooking appliance. The air guide 300 may be disposed in the flow path (hereinafter referred to as “exhaust path”) of air discharged from the front space S to the front of the cooking appliance.

The air guide 300 arranged in this way may include a first guide part 310 and a second guide part 320. The first guide part 310 and the second guide part 320 may be provided in the form of a frame that is longer in width compared to the length and thickness and thinner than the length and width.

The air guide 300 including the first guide part 310 and the second guide part 320 as described above divides the space between the control panel 200 and the door 150 into the first space S1 and the second guide part 320. It can be divided into two spaces (S2).

The first guide portion 310 of the air guide 300 may be disposed in the vertical center of the front space (S). And the second guide part 320 disposed on the rear side of the first guide part 310 may block the space between the door exhaust port 152 and the exhaust port 122.

Accordingly, the flow of air (hereinafter referred to as “first exhaust air”) introduced into the front space (S) through the exhaust port 122 is directed to the first space (S1) by the second guide part 320. can be induced.

That is, the first exhaust air discharged from the upper side of the second guide part 320 cannot move toward the door exhaust port 152 and the second space (S) around it due to the second guide part 320, and 2 It flows toward the first space (S1) through the upper space of the guide part 320.

The first exhaust air flowing in this way may be discharged to the front of the cooking appliance through the first space (S1), which is a space biased toward the upper side of the front space (S).

The first exhaust air is. Since it is discharged at a high temperature, it shows an upward flow while passing through the front space (S). Therefore, even if the second guide part 320 is formed to be inclined upwardly toward the front, the second guide part 320 does not have much influence on the flow of the first exhaust air.

The flow of the first exhaust air is hardly interrupted by the second guide part 320. Rather, the flow of the first exhaust air can be smoothly guided by the second guide part 320 formed to be inclined upwardly toward the front.

Additionally, the flow of air (hereinafter referred to as “second exhaust air”) introduced into the front space (S) through the door exhaust port 152 may be guided by the second guide unit 320. The flow of the second exhaust air may be guided toward the second space (S2) by the second guide unit 320.

That is, the second exhaust air discharged from the lower side of the second guide unit 320 is discharged into the first space S1 or exhaust port disposed on the upper side of the second guide unit 320 due to the second guide unit 320. It cannot move toward (122), but flows toward the second space (S2) disposed on the lower side of the second guide portion (320).

The second exhaust air flowing in this way may be discharged to the front of the cooking appliance through the space biased toward the lower part of the front space S, that is, the second space S2.

Since the second guide part 320 is formed to be inclined upwardly toward the front, the resistance of the second guide part 320 that blocks the flow of the second exhaust air can be maintained at a very weak level. The flow of the second exhaust air directed forward from the door exhaust port 152 disposed on the lower side of the second guide unit 320 can be smoothly guided by the second guide unit 320.

Due to the action of the second guide unit 320 as described above, the first exhaust air and the second exhaust air each flow forward through separate spaces. Accordingly, the first exhaust air is not directed toward the door exhaust port 152 and the second exhaust air is not directed toward the exhaust port 122.

When the flow of the first exhaust air and the flow of the second exhaust air are strong and the flow of the first exhaust air and the flow of the second exhaust air merge in the front space (S), the flow path resistance within the front space (S) As this increases, there is a possibility that vortices may be generated within the front space (S).

If a vortex occurs in the front space (S), the air flowing into the front space (S) may not be properly discharged to the outside of the cooking appliance, or the air in the front space (S) may be discharged from the door through the door exhaust port (152). (150) Internal reflux may occur.

Considering this, in this embodiment, the second guide part 320 is arranged to block between the door exhaust port 152 and the exhaust port 122. Accordingly, when the flows of the first exhaust air and the second exhaust air are strong, the first exhaust air and the second exhaust air can individually flow forward through separate spaces.

In this way, when a flow of air branched by the air guide 300 is formed within the front space (S), the possibility of generating a vortex within the front space (S) can be significantly reduced.

In general, the temperature of the first exhaust air discharged from the electrical equipment room 103 may be higher than the temperature of the second exhaust air discharged from the door 150. Considering this, the air guide 300 of the present embodiment can induce a flow of air such that the first discharged air flows through the first space (S1).

That is, the air guide 300 of this embodiment allows the first exhaust air, which is relatively hotter than the second exhaust air, to flow through the first space (S1), which is a space biased toward the upper side of the front space (S). can be induced. This air guide 300 can guide the exhaust flow so that the gap between the first exhaust air flow and the door 150 increases.

Accordingly, exhaust is discharged toward the front of the cooking appliance from the side farthest from the door 150 in the front space (S), so the distance between the hot air discharged to the front of the cooking appliance and the door 150 becomes correspondingly greater.

As the distance between the hot air discharged to the front of the cooking appliance and the door 150 increases, the risk of the temperature of the door 150 rising due to contact between the hot air and the door 150 decreases.

In addition, because the air discharged from the exhaust port 122 and the door exhaust port 152 moves through a space biased toward the upper part of the front space (S), the air discharged from the exhaust port 122 moves downward and reaches the door exhaust port 152. The possibility that air flowing into the door 150 or discharged from the door exhaust port 152 will flow back into the door 150 is reduced.

Since the air flow toward the front of the cooking appliance is directed toward the upper side away from the door exhaust port 152, the possibility of air flowing into the front space S flowing into the inside of the door 150 is very low.

To this end, the second guide unit 320 blocks the second space S2, which is a space adjacent to the door exhaust port 152, to prevent the movement of air through the space adjacent to the door exhaust port 152.

Additionally, the second guide unit 320 can induce upward movement of air introduced into the front space (S) by forming a blocking wall inclined upwardly toward the front.

As described above, the air guide 300 of this embodiment can not only effectively suppress the temperature of the door 150 from increasing due to hot air discharged to the front of the galley, but also can effectively prevent the temperature of the door 150 from increasing in the battlefield or inside the door 150. Backflow of discharged air into the door 150 can also be effectively prevented.

According to this embodiment, the second guide part 320 is disposed between the first guide part 310 and the main body 100, and may be arranged to be spaced apart from the main body 100 in the front and rear directions. More specifically, the second guide part 320 is disposed between the first guide part 310 and the front panel 120, and may be arranged to be spaced apart from the front panel 120 in the front and rear directions.

A connection space S3 may be formed between the second guide part 320 and the main body 100 that are spaced apart in this way. The connection space S3 may form a passage connecting the first space S1 and the second space S2 on the rear side of the second guide part 320.

When the flows of the first exhaust air and the second exhaust air are strong, air may not flow through the connection space S3. This is because the connection space S3 is located very close to the exhaust port 122 and at the rear of the door exhaust port 152.

However, when the flow of the first exhaust air and the flow of the second exhaust air are weak, air may flow through the connection space S3. At this time, mixing between the first exhaust air and the second exhaust air can be achieved through the connection space (S3), and the mixed exhaust air can be discharged through the first space (S1) and the second space (S2). .

In this case, since air discharged at a high temperature can be mixed with air discharged at a lower temperature, the maximum temperature of the air discharged to the front of the cooking appliance can be lowered.

When the flow of the first exhaust air and the flow of the second exhaust air are weak, the flow resistance in the front space S is not large. Therefore, even if the first exhaust air and the second exhaust air are mixed as described above, exhaust to the front is not smooth or a phenomenon in which air in the front space (S) flows back into the door 150 occurs. It is unlikely to happen.

As described above, the cooking appliance of this embodiment can separate or mix the flows of the first exhaust air and the flows of the second exhaust air and perform exhaustion depending on the situation.

The cooking appliance of this embodiment can provide both the effect of suppressing exhaust performance deterioration due to eddy currents and the occurrence of exhaust backflow problems into the inside of the door, as well as the effect of suppressing exhaust exhaust from being generated at an excessively high temperature.

Meanwhile, the inner cover protrusion 220 that secures the air guide 300 to the control panel 200 may be disposed between the exhaust port 122 and the exhaust port 122. The inner cover protrusion 220 obscures the partition wall 121 from the front of the partition wall 121 so that it is not visible, and is disposed in a position that does not overlap the exhaust port 122, thereby causing damage to the partition wall 121 due to the cover projections 210 and 220 or the air guide 300. The generated flow path resistance can be effectively lowered.

In addition, the front end of the air guide 300 disposed on the front side of the front space S within the front space S as described above overlaps in the vertical direction with at least a portion of the windshield 153 of the door 150. It can be placed in any location.

As an example, the front end of the air guide 300 may be disposed in the same position as the rear end of the windshield 152 in the front-to-back direction, or may be disposed in a position that protrudes further forward than the rear end of the windshield 152. there is.

In this way, the air guide 300 is disposed at a position biased toward the front within the front space (S), so that the flow of air flowing from the front space (S) toward the front of the cooking appliance is further controlled by the air guide (300). Can be guided effectively.

In addition, by arranging the air guide 300 in a position where the air guide 300 can be easily seen from the outside of the cooking appliance as described above, the aesthetics provided by the air guide 300 can be expressed more effectively.

Meanwhile, in the process of hot air being discharged from the front space (S), some of the discharged air comes into contact with the bottom of the control panel 200, which may cause condensation to form on the bottom of the control panel 200.

In this way, when the condensed water condensed on the bottom of the control panel 200 falls on the top of the door 150, the water that hits the door 150 splashes around the door 150 and contaminates the surrounding area.

As described above, when the air guide 300 is placed in a position biased toward the front within the front space (S), the control panel 200 and the door are kept from condensation water condensed on the bottom of the control panel 200 to fall on the door 150. (150) It can be a barrier between them.

Because the distance between the control panel 200 and the air guide 300 is much closer than the distance between the control panel 200 and the door 150, even if condensate falls on the air guide 300, the amount of water splashed around it is small. There won't be much.

Additionally, condensed water falling on the air guide 300 may flow down the inner surface of the door 150 along the second guide portion 320 formed to be inclined downward toward the rear. That is, the air guide 300 can guide the flow of condensate that falls on the air guide 300 to the inner surface of the door 150.

Condensed water flowing down along the inner surface of the door 150 does not flow out of the cooking appliance, but can be contained in a drip tray installed on the bottom of the cooking appliance.

That is, by using the air guide 300 arranged in the above-mentioned form, the occurrence of contamination around the cooking appliance due to condensate can be significantly reduced.

In this embodiment, the front end of the air guide 300 may be disposed at a position that coincides with at least one of the front end of the control panel 200 and the front end of the door 150 in the front-to-back direction.

For example, when viewed from the side, the front end of the air guide 300 and the front lower edge of the control panel 200 may be arranged on the same line. Additionally, when viewed from the side, the front end of the air guide 300 and the front upper edge of the door 150 may be arranged on the same line.

By arranging the air guide 300 in this way, the positions of the control panel 200, the air guide 300, and the door 150 are aligned and the appearance of the cooking appliance appears more balanced, improving the aesthetics of the cooking appliance. This could be improved further.

In this way, the arrangement of the air guide 300 to improve the aesthetics of the cooking appliance is possible because the air guide 300 is skewed to the front side of the front space (S) within the front space (S).

That is, the air guide 300 of this embodiment is disposed biased toward the front side of the front space (S) within the front space (S), thereby suppressing the generation of vortices within the front space (S) and improving the aesthetics of the cooking appliance. It can also provide an improving effect.

The present invention has been described with reference to the embodiments shown in the drawings, but these are merely exemplary, and those skilled in the art will recognize that various modifications and other equivalent embodiments are possible therefrom.
