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 used to cook 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 food they cook, cooking appliances can be classified into open and closed cooking appliances depending on the type of space where food is placed. Closed cooking appliances include ovens and microwaves, while open cooking appliances include cooktops and hobs.

A closed cooking appliance is a cooking appliance that shields the space where food is located and cooks the food by heating the shielded space. A closed cooking appliance is provided with a cooking chamber, which is a space where food is placed and shielded when food is to be cooked. This galley is actually a space where food is cooked.

The sealed cooking appliances are roughly divided into gas ovens and electric ovens depending on the type of heat source.

Gas ovens use gas as fuel and supply gas to a burner to ignite it, allowing food to be cooked by a flame in the burner.

Electric ovens, unlike gas ovens, use electricity as a heat source. These electric ovens use a method that allows food to be cooked by heat emitted from a heater.

Recently, steam ovens that cook food using high-temperature steam have been released.

A steam oven is an oven that sprays steam into the cooking chamber using high-temperature steam and has the function of controlling humidity by the amount of steam. It prevents food from drying out and enables large-scale, multi-stage cooking.

In addition, steam ovens can provide complex functions, such as maintaining the taste and aroma of dishes by blocking evaporation of flavors and aromas.

In general, the steam oven includes a cabinet that forms the exterior, a cavity disposed inside the cabinet to form a cooking chamber, a door that opens and closes the front opening of the cooking chamber, and a steam supply unit that supplies steam to the inside of the cooking chamber. It is provided in the form

Additionally, the steam supply unit may include a steam generator that generates steam, and a water supply device that supplies water to the steam generator.

Between the water supply device and the steam generator, a water supply pipe is connected so that the water inside the water tank can be moved to the steam generator. The steam generator includes a water storage unit that accommodates water supplied from the water supply device, and a heater that generates steam by heating the water inside the water storage unit.

In the steam oven as described above, water injected through the water supply device flows into the water storage unit through the water supply pipe, the water flowing into the water storage unit is heated by the heater to generate steam, and the steam generated in this way flows into the cooking chamber. Cooking is done using steam as it flows in and circulates inside the cooking chamber.

In the steam oven as described above, the water supply device may be placed in the battlefield space, which is a space formed at the upper part of the cooking chamber.

The water supply device may be provided to be withdrawn from the front of the battlefield space. This water supply device may include a housing and a water tank.

The housing is fixed in the battlefield space. The housing forms an accommodating space inside that can accommodate a water tank, and the front of the housing is open toward the front.

The water tank is installed in the housing so that it can move forward and backward in the receiving space inside the housing. This water tank can be pulled out to the front of the battlefield space.

On the front side of the cavity, a front panel may be provided. The front panel may be disposed on the front side of the cavity to form the front exterior of the steam oven. This front panel shields the front edge area of the cavity and can form the front appearance of the steam oven.

Additionally, a portion of the front panel may extend to the upper side of the cavity and be disposed on the front side of the full-length space. In this case, a portion of the front panel disposed on the front side of the battlefield space serves as a cover that covers the battlefield space from the front side.

The front panel formed as described above can form the front exterior of the steam oven that is exposed when the door opens the cooking chamber. This front panel can shield the front edge area of the cavity and the overall space from the front side and form the front exterior of the steam oven.

The steam oven may be further provided with a control panel for controlling the operation of the steam oven and displaying the operating status. This control panel can be placed on the upper side of the door that closes the galley.

The water tank can be drawn out to the front of the battlefield space through the front panel disposed in front of the battlefield space. For this purpose, an open hole is formed in the front panel to form a passage through which the water tank can pass. This open hole is located in the area between the galley and the control panel.

When the door opens the galley, the open hole is exposed, and when the door closes the galley, the open hole is not exposed. Therefore, the water tank can be withdrawn when the door opens the galley, and when the door closes the galley, the opening hole and water tank are not exposed to the outside.

On the other hand, a steam oven with a smaller size than the steam oven with the above structure, that is, a steam oven with a cooking chamber with a smaller volume than the steam oven with the above structure, or a steam oven with the same cooking chamber volume but a smaller overall size compared to the steam oven with the above structure. In the case of an oven, the distance between the cooking chamber and the control panel may be shortened compared to a steam oven of the above structure.

In such steam ovens (hereinafter referred to as “small and medium-sized steam ovens”), it is difficult to secure a space for placing a water supply device between the cavity where the cooking chamber is formed and the control panel.

In order to place a water supply device between the cooking chamber and the control panel, the vertical gap between the upper surface of the cavity and the control panel must be secured enough to allow placement of the water supply device, but this is not easy in small and medium-sized steam ovens. In order to ensure the above-mentioned spacing in a small to medium-sized steam oven, only the top and bottom length may be excessively long compared to the overall size of the small to medium-sized steam oven.

In these small and medium-sized ovens, the control panel instead of the front panel serves as a cover that covers the battlefield space from the front. Accordingly, the water supply device, more specifically the water tank, is placed in the area behind the control panel.

However, when the water tank is placed in the rear area of the control panel like this, an open hole forming a passage through which the water tank can pass must be formed in the control panel.

In this way, the open hole formed in the control panel is always exposed to the outside of the steam oven, so it can be an element that spoils the aesthetics of the steam oven.

Prior Document 1 (European Patent Publication No. 3080517) discloses a home appliance including a movable control panel.

In Prior Literature 1, a storage space in which home appliance parts are accommodated is disposed on the upper side of the home appliance. The control panel is placed on the upper side of the door and is provided to cover the front of the storage space.

The control panel is provided to be movable in the up and down directions. When the control panel is moved upward, the storage space becomes accessible without restrictions, and thus the tank can be easily removed from or inserted into the storage space.

When the control panel is moved downward, the front of the storage space is covered by the control panel, and thus access to the storage space and the tank inserted therein is also restricted.

The movement path of the control panel in Prior Document 1 can be divided into a first path and a second path. Between the closed position where the control panel closes the storage space and the open position where the control panel completely opens the storage space, the first path is the lower section including the closed position, and the second path is between the end of the first path and the open position. It is the upper section of .

In the first path, the control panel can be moved by a moving device including a driving motor. In the second path, no motor driving force is applied to the control panel, and the control panel can be moved by user manipulation.

According to this, after the control panel is automatically moved in the first path, the storage space of the control panel is opened by manual movement of the control panel in the second path.

In small and medium-sized steam ovens, the front panel does not cover the storage space, and instead, the control panel serves as a cover that covers the storage space from the front. However, when the control panel is opened to withdraw or insert the tank into the storage space, the storage space is completely opened to the front.

If the storage space is completely opened like this, not only does it not look good, but it can also cause problems with various foreign substances or contaminants flowing into the storage space while the control panel is open.

However, Prior Document 1 does not disclose what and how the front of this storage space is covered.

The storage space can be covered by this separate panel. In this case, there is a need to design an installation structure for the panel covering the storage space. Additionally, there is a need to design the installation structure of the tank and tank storage structure against the panel.

On the other hand, if the shape of the first inner wall portion (131a) is deformed due to the load applied to the first inner wall portion (131a), the effect of this deformation of the first inner wall portion (131a) is on the second inner wall portion ( 131b) also applies. That is, when the first inner wall portion 131a sags toward the lower side, a phenomenon in which the second inner wall portion 131b connected to the first inner wall portion 131a also sags toward the lower side may occur.

If sagging of the second inner wall portion 131b occurs, the second inner wall portion 131b may press the water tank 320 toward the lower side, causing the water tank 320 to tilt, and the second inner wall portion 131b may press the water tank 320 downward. Friction between the unit 131b and the water tank 320 increases, which may cause problems in which the water tank 320 cannot be moved smoothly.

In addition, if the second inner wall portion 131b sags, the appearance is not good, and noise increases when the water tank 320 is moved due to increased friction between the second inner wall portion 131b and the water tank 320. Problems may arise.

Unlike the first inner wall portion 131a, the second inner wall portion 131b is not coupled to the housing 310. Therefore, the second inner wall portion 131b is more likely to be deformed than the first inner wall portion 131a when an external force in the downward direction is applied.

Considering this, in this embodiment, a plurality of reinforcing ribs 133c may be formed on the upper surface of the second inner wall portion 131b. These reinforcing ribs 133c may serve to support the second inner wall portion 131b so that the second inner wall portion 131b does not easily sag downward.

According to this embodiment, the first inner wall portion 131a can effectively resist the load applied by the water tank 320 by being supported by the housing 310 combined with the first inner wall portion 131a. there is.

Additionally, if the load resistance of the first inner wall portion 131a increases, the degree to which the load applied to the first inner wall portion 131a affects the second inner wall portion 131b may be reduced.

Additionally, the second inner wall portion 131b can effectively resist the force applied to the second inner wall portion 131b by being supported by the reinforcing ribs 133c.

In this way, the second inner wall is designed to prevent the second inner wall portion 131b from sagging due to the interaction of the force supporting the first inner wall portion 131a and the force supporting the second inner wall portion 131b. Support for the portion 131b can be achieved very effectively.

Accordingly, the cooking appliance of this embodiment has the following characteristics: sagging of the second inner wall portion 131b, tilting of the water tank 320 resulting therefrom, defective extraction/insertion of the water tank 320, damage to the exterior of the cooking appliance, increased noise, etc. The occurrence of the same problem can be effectively suppressed.

Meanwhile, the second front panel 130 may further include an outer wall portion 131d. The outer wall portion 131d may be disposed on the upper side of the second inner wall portion 131b. Like the second inner wall portion 131b, this outer wall portion 131d may protrude rearward from the panel body portion 131.

In addition, the second front panel 130 may further include a connecting rib 133d. The connecting rib 133d may protrude rearward from the panel body 131. This connecting rib (133d) may be provided in the form of connecting the outer wall portion (131d) and the second inner wall portion (131b).

The connecting rib 133d connects the second inner wall portion 131b to the outer wall portion 131d and can improve the strength of the second inner wall portion 131b. Of course, these connecting ribs 133d can also serve to improve the strength of the panel body 131.

This first downward coupling portion 311e may be coupled to the duct portion 143 at the upper side of the duct portion 143.

The housing 310 may be coupled to the duct portion 143 by coupling the first lower coupling portion 311e and the duct portion 143. A plurality of first lower coupling portions 311e may be disposed in the front-back direction, and thus the housing 310 and the duct portion 143 may be coupled at multiple points in the front-back direction.

The second lower coupling portion 311f may protrude from the housing 310 toward the blocking plate portion 141. More specifically, the second lower coupling portion 311f may protrude downward from a corner connecting the bottom portion 311 and the side portion 313. This second lower coupling portion 311f may be coupled to the blocking plate portion 141 at the upper side of the blocking plate portion 141.

The housing 310 may be coupled to the blocking plate portion 141 by coupling the second lower coupling portion 311f and the blocking plate portion 141. At this time, the second lower coupling portion 311f may protrude toward the lower side from the housing 310 at a length corresponding to the height difference between the blocking plate portion 141 and the duct portion 143.

In this embodiment, the duct portion 143 is illustrated as being disposed approximately at the lateral center within the overall space 103. And the housing 310 is disposed biased to one side in the lateral direction within the battlefield space 103.

Accordingly, the first lower coupling portion 311e coupled to the duct portion 143 and the second lower coupling portion 311f coupled to the blocking plate portion 141 may be arranged to be spaced apart laterally. That is, one lateral side of the housing 310 is coupled to the duct portion 143 by the first downward coupling portion 311e, and the other lateral side of the housing 310 is coupled to the blocking plate portion by the second downward coupling portion 311f.

The duct portion 143 can be maintained in a cooled state by cold air flowing inside the duct portion 143. Accordingly, a partial area of the housing 310 in contact with the duct portion 143 may be cooled by the duct portion 143.

In addition, some other areas of the housing 310 are arranged to be spaced apart from the blocking plate portion 141, so that they are less affected by the blocking plate portion 141, which maintains a relatively high temperature compared to the duct portion 143.

That is, by maintaining the area of the housing 310 spaced apart from the blocking plate 141, the influence of heat transmitted from the blocking plate 141 can be avoided.

The front of the water tank 320 may be formed in a shape that includes a plane parallel to the vertical plane formed by the second front panel 130. Additionally, the front of the water tank 320 may be formed to be substantially the same plane as the vertical plane formed by the second front panel 130.

Edge areas on both sides of the front of the water tank 320 may be formed in a curved shape. This is to reduce the possibility of collision between the water tank 320 and the second front panel 130 during the withdrawal process of the water tank 320 and to reduce the risk of injury due to the water tank 320.

When the control panel 200 blocks the second front panel 130, the water tank 320 is not exposed to the front of the cooking appliance. However, when the control panel 200 opens the second front panel 130, the water tank 320 may be exposed to the front of the cooking appliance.

The user can withdraw the water tank 320 exposed to the front from the inside of the cooking appliance, or reinsert the withdrawn water tank 320 into the cooking appliance through the access hole 132.

A gripping portion 325 may be provided on the water tank 320 so that the user can hold the water tank 320 with his or her hand. This gripping portion 325 may be provided to be exposed toward the front of the water tank 320.

The recessed surface portion 325a may be disposed at a predetermined distance from the front to the rear of the water tank 320. And the connection surface portion 325b can connect the front of the water tank 320 and the recessed surface portion 325a.

An insertion space 326 surrounded by the connection surface portion 325b and the recessed surface portion 325a may be formed on the lower side of the connection surface portion 325b. This insertion space 326 may be opened forward.

As an example, the recessed surface portion 325a may form a vertical wall extending from the bottom of the water tank 320 to the top. And the connection surface portion 325b may be connected to the top of the recessed surface portion 325a.

Accordingly, the insertion space 326 can be disposed on the front side of the recessed surface portion 325a and the lower side of the connection surface portion 325b. This insertion space 326 is disposed in a position biased toward the lower side of the water tank 320, and can be opened in a position biased toward the lower side of the front of the water tank 320.

In this embodiment, the connection surface portion 325b may be formed to be inclined upward toward the rear side. That is, the connection surface portion 325b may be formed in a shape whose position becomes higher toward the rear.

Accordingly, the insertion space 326 may be formed in a shape that expands further toward the upper side toward the rear. By forming the insertion space 326 in this shape, a space for the user's fingers can be effectively secured within the insertion space 326, allowing the user to hold the water tank 320 more stably. .

In addition, the water tank 320 may further include a gripping protrusion 325c. The gripping protrusion 325c is provided on the gripping portion 325 and may be formed to protrude from the connection surface portion 325b.

On the connection surface portion 325b, a plurality of gripping protrusions 325c may be arranged to be spaced apart from each other at a predetermined distance in the front-back direction. Each gripping protrusion 325c may be formed to protrude downward from the connection surface portion 325b.

The connection surface portion 325b is a portion where the user's fingers touch when the user puts his/her hand inside the grip portion 325. By forming the grip protrusion 325c on this connection surface portion 325b, the user can hold the water tank 320 more stably and effectively prevent the water tank 320 from slipping from the fingertips. do.

Meanwhile, including FIGS. 9 and 17 to 19, a sliding protrusion 327 may be disposed between the housing 310 and the water tank 320. The sliding protrusion 327 may be disposed between the bottom portion 311 of the housing 310 and the bottom surface of the water tank 320.

In this embodiment, the sliding protrusion 327 is illustrated as being provided in the water tank 320. These sliding protrusions 327 may be formed to protrude downward from the bottom of the water tank 320.

As another example, the sliding protrusion 327 may be provided on the housing 310. In this case, the sliding protrusion 327 may be formed to protrude upward from the bottom portion 311 of the housing 310.

In the water tank 320, a pair of sliding protrusions 327 may be disposed to be spaced apart from each other at a predetermined distance in the lateral direction. Each sliding protrusion 327 may be formed to extend in the front-back direction.

The lateral length of each sliding protrusion 327 may be set to be much shorter than the lateral length of the bottom portion 311 of the housing 310. That is, the sliding protrusion 327 may be formed in the shape of a long, thin rod.

The entire bottom of the water tank 320 does not contact the bottom portion 311 of the housing 310, but contacts the bottom portion 311 of the housing 310 through the sliding protrusion 327. can do. That is, the area where contact is made between the bottom of the water tank 320 and the bottom part 311 of the housing 310 may be limited to the contact area between the sliding protrusion 327 and the bottom part 311.

The sliding protrusion 327 formed as described above may serve to reduce the frictional force generated when the water tank 320 moves by reducing the contact area between the housing 310 and the water tank 320.

Meanwhile, in the housing 310, a pair of guide protrusions 317 may be disposed to be spaced apart from each other at a predetermined distance in the lateral direction. Each guide protrusion 317 protrudes from the bottom portion 311 toward the upper side and may be formed to extend in the front-back direction.

The vertical length of the guide protrusion 317 may be set shorter than the vertical length of the sliding protrusion 327. That is, while the sliding protrusion 327 contacts the bottom 311 of the housing 310, the guide protrusion 317 does not contact the bottom of the water tank 320.

The lateral spacing between the pair of guide protrusions 317 may be set wider than the lateral spacing between the pair of sliding protrusions 327. Additionally, a pair of sliding protrusions 327 provided in the water tank 320 may be disposed between a pair of guide protrusions 317.

In this way, the sliding protrusion 327 disposed between the pair of guide protrusions 317 can move forward and backward within an area limited between the pair of guide protrusions 317. That is, the guide protrusion 317 may play a role in suppressing the water tank 320 from shaking in the lateral direction while it moves forward and backward by regulating the movement area of the guide protrusion 317.

In addition, a lateral protrusion 329 may be provided on at least one of the housing 310 and the water tank 320. The lateral protrusion 329 may protrude from the guide protrusion 317 or the sliding protrusion 327 so as to be disposed between the guide protrusion 317 and the sliding protrusion 327 that face each other in the lateral direction.

In this embodiment, it is illustrated that the water tank 320 is provided with a lateral protrusion 329. On the bottom of the water tank 320, a plurality of lateral protrusions 329 may be arranged to be spaced apart at predetermined intervals in the front-back direction. Each lateral protrusion 329 protrudes laterally from the sliding protrusion 327 and may be disposed between the sliding protrusion 327 and the guide protrusion 317 that face each other in the lateral direction.

For example, a pair of guide protrusions 317 are disposed between a pair of guide protrusions 317, and lateral protrusions 329 are positioned between the guide protrusions 317 and sliding protrusions 327 that face each other in the lateral direction. can be placed.

At this time, the sum of the lateral lengths of the pair of lateral protrusions 329 is set equal to the value obtained by subtracting the lateral spacing between the pair of sliding protrusions 327 from the lateral spacing between the pair of guide protrusions 317. It can be.

That is, the lateral spacing between the guide protrusion 317 and the sliding protrusion 327 facing each other in the lateral direction may be set equal to the lateral length of the lateral protrusion 329.

Accordingly, the space between the guide protrusions 317 and the sliding protrusions 327, which face each other laterally, is filled with the lateral protrusions 329, and the sliding protrusions 327 only move in the front-back direction between the pair of guide protrusions 317. It becomes movable and cannot move laterally.

The lateral protrusions 329 may serve to regulate the lateral movement of the water tank 320 moving forward and backward in the passage formed between the pair of guide protrusions 317. That is, the lateral protrusion 329 may play a role in suppressing lateral shaking of the water tank 320 while the water tank 320 moves forward and backward.

The lateral protrusion 329 can significantly reduce the contact area between the guide protrusion 317 and the water tank 320 compared to the case where the sliding protrusion 327 is in contact with the guide protrusion 317.

That is, the lateral protrusion 329 may serve to reduce the friction force generated when the water tank 320 moves by reducing the contact area between the guide protrusion 317 and the water tank 320.

Preferably, each lateral protrusion 329 may be formed in a curved shape. These lateral protrusions 329 can more effectively reduce the contact area between the guide protrusions 317 and the lateral protrusions 329.

In addition, if the lateral protrusion 329 is formed in a curved shape, when the water tank 320 is inserted into the housing 310, the lateral protrusion 329 can be easily inserted into the area between the pair of guide protrusions 317. The effect of being able to do so may also be provided.

Referring to FIGS. 15, 16, and 19, the second front panel 130 may be provided with a lower groove portion 134. The lower groove portion 134 is provided on the front surface of the first inner wall portion 131a and may be exposed toward the front of the first inner wall portion 131a.

The lower groove portion 134 may be formed in a depressed shape from the front side to the rear side of the first inner wall portion 131a. The space surrounded by the lower groove portion 134 in the first inner wall portion 131a may be open to the upper and front sides.

Additionally, the lower groove portion 134 may be formed in a depressed shape from the top of the first inner wall portion 131a toward the lower side. The lower groove portion 134 formed in this way may be opened upward toward the grip portion 325. This lower groove 134 may be connected to the space inside the gripper 325, that is, the insertion space 326, in the vertical direction.

The lower groove 134 may serve to expand the front entrance of the insertion space 326 formed inside the gripper 325. This lower groove 134 can contribute to allowing the user to more easily reach into the grip portion 325 and hold the water tank 320.

Preferably, the upper end of the first inner wall portion 131a may be formed to slope downward toward the front side. Accordingly, a lower groove portion 134 having a concave shape toward the front and downward may be provided at the top of the first inner wall portion 131a.

FIG. 22 is a cross-sectional view taken along the line “X

20 to 22, the cooking appliance according to an embodiment of the present invention may further include an opening module 400. The opening module 400 is provided to push the control panel 200 located in the closed position forward and move it to the open position.

The opening module 400 may include a pushing member 410. The pushing member 410 is disposed on the rear side of the control panel 200 and may be rotatable. In this embodiment, the pushing member 410 is illustrated as being rotatable about a vertical axis.

The pushing member 410 may be formed in a cam shape. A portion of the pushing member 410 may protrude in a centrifugal direction compared to other portions. In this embodiment, the pushing member 410 contacts the rear of the control panel 200 at least once during one rotation and may be formed in a cam shape that can push the control panel 200 forward.

According to this, while the pushing member 410 rotates one revolution, contact may occur between the back of the control panel 200 and the pushing member 410. In this way, when contact occurs between the back of the control panel 200 and the pushing member 410, the pushing member 410 contacts the back of the control panel 200 and pushes the control panel 200 forward, controlling The panel 200 may move toward the open position while being pushed forward by the pushing member 410.

The open module 400 may be placed in the battlefield space 103. The pushing member 410 provided in the open module 400 may also be disposed in the battlefield space 103. That is, the pushing member 410 may be disposed on the rear side of the second front panel 130.

When the control panel 200 is in the closed position, the entire area of the pushing member 410 may be disposed on the rear side of the second front panel 130. When the pushing member 410 begins to rotate, a portion of the pushing member 410 may protrude toward the front of the second front panel 130.

A cam passing hole 136 may be provided in the second front panel 130. The cam passage hole 136 may be formed to penetrate the panel body 131 in the front-back direction. The cam passage hole 136 may form a passage necessary for the pushing member 410 to pass through the second front panel 130.

A portion of the pushing member 410 may protrude toward the front of the second front panel 130 through the cam passage hole 136. If the rotation of the pushing member 410 continues in this state, the pushing member 410 is positioned at a position (hereinafter, “standby position”) where the entire area of the pushing member 410 is disposed on the rear side of the second front panel 130. It can be returned to (referred to as).

The opening module 400 can tilt the control panel 200 located in the closed position toward the front at a set inclination. In this embodiment, the setting tilt is exemplified as the tilt of the control panel 200 at which the control panel 200 can be moved to the open position by its own weight.

For example, when the inclination of the control panel 200 in the open position is 0° and the inclination of the control panel in the closed position is 90°, the set inclination may be set to an inclination in the range of 30 to 60°. At this time, the setting tilt may change due to the location of the center of gravity of the control panel 200, the location of the center of rotation of the control panel 200, the characteristics of the hinge module 250, etc.

The pushing member 410 rotates when the opening module 400 operates to tilt the control panel 200 forward, and pushes the control panel 200 forward so that the control panel 200 is tilted by the set tilt. You can.

The inclination of the control panel 200 tilted forward can be adjusted by the distance at which the pushing member 410 pushes the control panel 200. And the distance at which the pushing member 410 pushes the control panel 200 may vary depending on the shape of the pushing member 410. For example, as the diameter and eccentricity of the pushing member 410 increase, the distance at which the pushing member 410 pushes the control panel 200 may increase.

As another example, the set tilt is exemplified as the tilt of the control panel 200 at which the control panel 200 can be moved to the open position only when additional external force is applied.

For example, the tilt of the control panel 200, which rotates forward rather than in the closed position but cannot rotate to the open position on its own if left as is, may be set to a set tilt.

In this case, after the primary opening operation of the control panel 200 is performed by the operation of the opening module 400, the control panel 200 can be moved to the open position only when the user manually pulls it forward.

At this time, the setting inclination is a value that allows the control panel 200 to be located in a position where it is easy for the user to grab and pull the control panel 200, but where the control panel 200 cannot be moved to the open position due to its own weight. can be set.

Accordingly, the effect of allowing the user to easily and conveniently move the control panel 200 to the open position and the effect of preventing the fully opening operation of the control panel 200 due to unintended misoperation will be provided. You can.

Meanwhile, the opening module 400 may further include a driving unit 420. The driving unit 420 is provided to provide power to rotate the pushing member 410. This driving unit 420 may include a driving motor that generates rotational force to rotate the pushing member 410.

In addition, the opening module 400 may further include a pushing member detection unit 430. The pushing member detection unit 430 may be provided to control the operation of the driving unit 420. According to this embodiment, the pushing member detection unit 430 detects the position of the pushing member 410, and the control unit that controls the operation of the cooking appliance can control the operation of the driving unit 420 according to the detection result. .

The pushing member detection unit 430 may include a sensor that contacts at least a portion of the pushing member 410 and detects the position of the pushing member 410. In this embodiment, the pushing member detection unit 430 is illustrated as being provided in a form including a microswitch type sensor. This pushing member detection unit 430 can be turned on/off according to the movement of the actuator protruding on the microswitch.

The pushing member 410 may be provided with a contact protrusion 415. The contact protrusion 415 may be formed to protrude from the pushing member 410. These contact protrusions 415 may rotate together with the pushing member 410 and change their positions. Preferably, the contact protrusion 415 may be disposed adjacent to the outer peripheral surface of the pushing member 410.

The contact protrusion 415 may be provided to contact the actuator protruding on the sensor of the pushing member detection unit 430. The sensor may be turned on/off according to the movement of the actuator in contact with the contact protrusion 415, and the on/off sensor may generate a signal. In this way, the position of the pushing member 410 can be determined by the signal generated by the micro switch.

As an example, the sensor of the pushing member detection unit 430 may be placed on the upper side of the pushing member 410. The actuator of this sensor may protrude downward toward the pushing member 410. Correspondingly, the contact protrusion 415 may protrude upward from the pushing member 410 toward the sensor.

According to this embodiment, the pushing member detection unit 430 and the contact protrusion 415 may be provided to determine the position of the pushing member 410. More specifically, the pushing member detection unit 430 and the contact protrusion 415 may be provided to determine whether the pushing member 410 has returned to the standby position.

According to this, the position of the contact protrusion 415 can be set to a position where it can contact the actuator of the sensor when the pushing member 410 returns to the standby position. In this case, when the pushing member 410 returns to the standby position, the sensor of the pushing member detection unit 430 turns on, and accordingly, the operation of the drive unit 420 stops, and the position of the pushing member 410 returns to the standby position. It can be maintained.

The control panel 200 may be provided with a plurality of buttons for setting the operation of the heating unit, as well as a button for setting the opening and closing operation of the control panel 200 (hereinafter referred to as the “control panel opening and closing button”). It can be provided.

When the user presses the control panel open/close button, the drive unit 420 starts operating, and accordingly, the pushing member 410 may start rotating. The pushing member 410 that has started rotating in this way can push the control panel 200 forward.

The control panel 200 pushed forward in this way can be tilted by the set tilt and then moved to the open position. At this time, the control panel 200 can be moved to the open position by its own weight while being tilted by the set inclination.

As another example, while the control panel 200 is tilted at a tilt similar to the set tilt, the user may manually move the control panel 200 to the open position.

Meanwhile, when the pushing member 410 rotates as described above, the contact protrusion 415 also moves together with the pushing member 410. When the moving contact protrusion 415 comes into contact with the actuator of the sensor, as shown in FIG. 23, the sensor turns on and generates a signal according to the movement of the actuator in contact with the contact protrusion 415.

As a result of the signal generated by the sensor, the operation of the driving unit 420 stops, and the movement of the pushing member 410 also stops accordingly. At this time, the movement of the pushing member 410 stops at the standby position, and the position of the pushing member 410 can be maintained at the standby position. Accordingly, the pushing member 410 does not protrude to the outside of the main body 100 but remains hidden inside the main body 100.

When the position of the control panel 200 is changed to the open position, as shown in FIG. 4, the second front panel 130, which was hidden on the rear side of the control panel 200, is exposed to the front side. In this state, if the pushing member 410 remains protruding forward of the second front panel 130, the appearance is not good, and when the control panel 200 returns to the closed position, the control panel ( A collision may occur between 200) and the pushing member 410.

If a collision occurs between the control panel 200 and the pushing member 410 when the control panel 200 returns to the closed position, the user may be surprised by the noise generated during the collision, and the control panel 200 or the open position may be Damage to the module 400 may occur. Additionally, a problem may occur in which the movement of the control panel 200 to the closed position is not completed properly.

Considering this, in this embodiment, the pushing member 410, which has completed the task of pushing the control panel 200, stops at the standby position and is then maintained in the standby position. To this end, the position of the pushing member 410 is detected by the pushing member detection unit 430, and the operation of the pushing member 410 and the driving unit 420 that rotates it can be controlled based on the detection result.

As a result, the cooking appliance of this embodiment can effectively prevent noise from being generated or damage to the control panel 200 or the opening module 400 during the opening and closing process of the control panel 200.

In addition, the cooking appliance of this embodiment not only maintains the rear appearance of the control panel 200 to look good regardless of whether the control panel 200 is opened, but also allows the control panel 200 to be opened and closed smoothly. It can provide an effect that allows.

[Control panel opening and closing structure]

Referring to Figures 2 to 5, the cooking appliance of this embodiment may be provided in the form of a small or medium-sized steam oven.

In a cooking appliance provided in the form of a small or medium-sized steam oven, it is difficult to secure a space for placing the water supply device 300 between the cavity where the cooking chamber is formed and the control panel. In order to place a water supply device between the cooking compartment and the control panel, the vertical gap between the upper surface of the cavity and the control panel must be sufficient to allow placement of the water supply device, which is not easy in small and medium-sized steam ovens.

The control panel 200 of this embodiment provided in such a cooking appliance can serve as a cover that covers the water supply device 300, especially the water tank 320, from the front side. This control panel 200 may be provided in a form that covers the entire battlefield space 103 where the water supply device 300 is placed from the front side.

The front of the battlefield space 103 may be covered by the control panel 200, but when the control panel 200 moves to the open position, the inside of the battlefield space 103 opens to the front.

To prevent this, a second front panel 130 may be provided on the front of the battlefield space 103. The second front panel 130 is disposed on the front side of the battlefield space 103 and can serve as a cover that covers the battlefield space 103 from the front side.

Typically, the first front panel 120 may be made of a metal material to ensure structural rigidity and at the same time withstand high heat.

In comparison, the second front panel 130 may be formed of a synthetic resin material such as plastic. The second front panel 130 does not need to support heavy objects, and the area around the battlefield space 103 where the second front panel 130 is placed is compared to the area around the galley 101 where the first front panel 120 is placed. This is because the temperature is maintained at a fairly low level.

Considering this, the front of the battlefield space 103 can be covered by the second front panel 130 made of a light and inexpensive material instead of a heavy and expensive metal plate.

In order to withdraw the water tank 320 and reinsert the withdrawn water tank 320, a passage for entering and exiting the water tank 320 must be formed in the front of the battlefield space 103. This passage may be provided by an access hole 132 formed in the second front panel 130.

The water tank 320 can be accessed through the access hole 132, and the front of the water tank 320 mounted inside the battlefield space 103 is connected to the second front panel 130 through the access hole 132. can be exposed to the front of.

The control panel 200 blocks the second front panel 130 from the front and can block exposure of the front of the water tank 320 and the access hole 132. This control panel 200 can be rotated to the open position to expose the access hole 132 to the front, and in this state, the water tank 320 can be accessed.

Meanwhile, the area where the second front panel 130 is disposed is an area extending long in the horizontal direction and is an area where bending deformation, etc. are likely to occur. This area is an area that would not be exposed if the control panel 200 was not provided to open and close the access hole 132.

However, if the control panel 200 is provided as disclosed in this embodiment, when the control panel 200 opens the access hole 132, the area where the second front panel 130 is placed is also connected to the access hole 132. They have no choice but to be exposed together.

If the second front panel 130 is formed integrally with the first front panel 120, the bending deformation generated in the second front panel 130 when the control panel 200 opens the access hole 132 A problem may arise where the back is exposed as is.

Additionally, the second front panel 130 is provided with structures related to opening the control panel 200, structures related to entering and leaving the water tank 320, and structures related to fixing the housing 310.

If the second front panel 130 is made of a metal material together with the first front panel 120, a problem arises in that it takes a lot of man-hours and costs to form the second front panel 130 with the above structures.

Considering this, in this embodiment, the second front panel 130 may not be formed integrally with the first control panel 120 but may be provided separately.

In addition, the second front panel 130, which is provided separately in this way, may be formed of a synthetic resin material such as plastic, unlike the first control panel 120 formed of a metal material. Preferably, the second front panel 130 may be made of a synthetic resin material that has a stiffness greater than that of the metal material forming the first control panel 120.

By providing the second front panel 130 in the form described above, bending deformation of the second front panel 130 can be prevented, and the control panel 200 is exposed when the access hole 132 is opened. The exterior of the second front panel 130 can appear smooth and neat.

In addition, as the second front panel 130 is provided in the form described above, structures related to the opening of the control panel 200, structures related to entering and exiting the water tank 320, structures related to fixing the housing 310, etc. Since they can be molded together with the second front panel 130 by a method such as injection, the second front panel 130 and related structures can be easily manufactured at a low cost.

Figure 24 is a diagram showing a change in inclination of the control panel of a cooking appliance according to an embodiment of the present invention, and Figure 25 is a perspective view showing a water tank withdrawal state of a cooking appliance according to an embodiment of the present invention.

Referring to FIGS. 22 to 24, the opening operation of the control panel 200 in this embodiment can be performed automatically.

For example, when the user presses the control panel open/close button, the open module 400 may push the control panel 200 forward (see FIGS. 22 and 23). Accordingly, the control panel 200 is tilted by the set inclination (see (a) of Figure 24), and then gradually tilted further forward due to its own weight (see (b) of Figure 24) and can be moved to the open position ( (see (c) in Figure 24).

As described above, by automatically opening the control panel 200, the cooking appliance of this embodiment not only eliminates the inconvenience caused by manual operation, but also reduces the risk of injury to the user that may occur during manual operation. It can provide a lowering effect.

The opening operation of the control panel 200 according to this embodiment is performed in such a way that the control panel 200 rotates downward and unfolds forward, which allows the opening operation of the control panel 200 to be performed automatically. can play an important role.

The control panel 200 of this embodiment rotates between the closed position and the open position, but may rotate around the bottom of the control panel 200. This control panel 200 can be moved to the open position by rotating around the bottom of the control panel 200.

The control panel 200 can rotate downward and move to the open position, and can be unfolded forward from the open position. The control panel 200 can be tilted by the set inclination by the operation of the opening module 400 and then moved to the open position by its own weight.

This is possible because the control panel 200 can rotate downward and unfold forward. If the control panel 200 is provided in a form that rotates upward, the opening operation of the control panel 200 cannot be automatically performed through the operation of the opening module 400 as described above.

Meanwhile, the control panel 200, which rotates to the open position and unfolds forward, may be placed between the door 150 and the water tank 320, as shown in FIGS. 24 and 25.

That is, when the control panel 200 is rotated to the open position and unfolded forward, the water tank 320 is pulled out of the battlefield space 103 or inserted into the battlefield space 103. It may be placed above the panel 200.

Additionally, when the control panel 200 is rotated to the open position and unfolded forward, the access hole 132 may be disposed above the control panel 200.

According to this, the control panel 200 that opens the entrance hole 132 for entering and exiting the water tank 320 may be placed at a lower position than the movement path of the water tank 320.

In this way, the control panel 200 is placed at a lower position than the movement path of the water tank 320, so that the control panel 200 does not act as an obstacle blocking the access hole 132 and the water tank 320 from the user's line of sight. It becomes impossible.

Accordingly, not only can the access hole 132 and the water tank 320 be clearly visible during the process of withdrawing or inserting the water tank 320, but also the user has to bend down to check the location of the access hole 132. Since there is no need for it, the convenience and stability of the cooking appliance can be improved.

In addition, the control panel 200, which is disposed at a lower position than the movement path of the water tank 320 as described above, supports the water tank 320 from the bottom during the process of withdrawing or inserting the water tank 320 and holds the water tank ( 320) can play a role in guiding the movement path.

Accordingly, the effect of allowing the user to withdraw or insert the water tank 320 more safely and conveniently can be provided.

Additionally, the control panel 200, which is unfolded to be disposed between the water tank 320 and the door 150 as described above, may serve as a structure that blocks the space between the door 150 and the water tank 320.

This control panel 200 may serve to block water from falling so that water flowing down from the water tank 320 does not fall toward the door 150 and contaminate the door 150 and its surroundings.

In addition, the control panel 200 may serve to block the heat discharged from the top of the door 150 and its surroundings (e.g., galley) from being transmitted toward the user who is withdrawing or inserting the water tank 320. there is.
