Description

Cooking appliances

[0001] The present disclosure relates to a cooking appliance, and more specifically, to a cooking appliance that allows the decorative panel of the door to be easily replaced and securely fixed to the decorative panel.

[0002] Various cooking appliances are being distributed, such as microwave ovens using microwaves, ovens using heaters, and cooktops.

[0003] Microwave ovens heat food by irradiating microwaves generated by a magnetron into a sealed cooking chamber to vibrate the water molecules of the food stored inside, while ovens heat food stored inside a cooking chamber by using a heater to heat the sealed cooking chamber.

[0004] In addition, cooking appliances are trending toward diversifying their functions, and cooking appliances are being developed that perform functions previously performed by two or more separate appliances in a single appliance.

[0005] The casing of such a cooking appliance can be fixed to the house in a built-in manner, or it can be supplied to consumers as a separate product and installed at a location desired by the user within the house.

[0006] FIG. 1 is a perspective view showing an example of a cooking appliance according to the prior art, and FIG. 2 is a front view of FIG. 1.

[0007] A cooking device (1) according to the prior art includes a casing (10) having a cavity (S) which is a cooking space for cooking food. A door (20) that opens and closes the cavity (S) via a lower hinge pivoting connector (30) may be provided at the front end of the casing (10). The lower end of the door (20) is connected to the hinge pivoting connector (30), and the upper end rotates forward relative to the hinge pivoting connector (30) to open and close the cavity (S).

[0008] Depending on the specifications, the door (20) may be equipped with a control panel (not shown) for cooking food in the cavity (S), and a wire harness for electrical connection between the control panel (not shown) provided in the casing (10) and the door (20) may be disposed in the hinge pivot connector (30) portion.

[0009] However, the cooking device (1) according to the prior art has a problem in that when the door (20) for opening the cavity (S) is opened, the hinge pivoting connector (30) with a complex structure including a wire harness is exposed to the user, which spoils the aesthetics of the product.

[0010] In addition, the cooking device (1) according to the prior art has a problem in that foreign substances such as oil generated from the food being cooked accumulate on the wire harness as well as the hinge pivot connector (30) even when the door (20) for closing the cavity (S) for cooking food is closed, requiring periodic cleaning.

[0011] In particular, when the cooking appliance (1) is provided as a built-in type, the product cannot be moved during cleaning, which leads to the problem of the cleaning time becoming longer.

[0012] A cooking device (1) according to the prior art has a problem in that foreign substances such as oil generated from the food being cooked accumulate on the wire harness as well as the hinge pivot connector (30) even when the door (20) for closing the cavity (S) for cooking food is closed, requiring periodic cleaning.

[0013] In addition, in the case of conventional technology, the door has a structure that makes it impossible to disassemble, or even if it can be disassembled, the front of the door cannot be easily replaced.

[0014] In the case of Patent Document 1, the structure is such that the front of the door cannot be easily replaced after the cooking appliance is installed, so there is a problem that it is difficult to change the design of the front of the door if the user wants to change it.

[0050] Additionally, a cooking device according to another embodiment of the present disclosure comprises a cavity forming a cooking chamber inside, a casing surrounding the cavity, and a door for opening and closing the cavity, wherein the door comprises a fixed frame having a coupling hole that is rotatably coupled to the casing, a deco panel having a hanger that is positioned on the front of the fixed frame and is supported by being hooked through the coupling hole, a locking bar that is slidably installed on the fixed frame to selectively restrict the upward movement of the hanger, and a top cover having a locking pin that is detachably coupled to the top of the fixed frame and restricts the sliding movement of the locking bar in the coupled state.

[0051]

[0052] Specific details of other embodiments are included in the detailed description and drawings.

[0053] According to the cooking appliance of the present disclosure, there is one or more of the following effects.

[0054] The present disclosure has the advantage that a deco hanger fixed to a deco panel of a door penetrates a hole formed in a fixed frame and is hooked onto the fixed frame, so the deco panel can be easily connected to the fixed frame, is stably fixed by the self-weight of the deco panel, and can be easily detached by the user.

[0055] In addition, the present disclosure has the advantage that, when the deco hanger is hooked onto the fixed frame by passing through a hole formed in the fixed frame, the locking bar slides to block the hole and restricts the deco hanger from moving upward, thereby stably fixing the deco hanger by the locking bar in addition to the self-weight of the deco hanger, and allowing it to be easily unlocked by sliding the locking bar.

[0056] In addition, the present disclosure has the advantage that the top cover is coupled to the upper part of the fixed frame to restrict the movement of the locking bar, and the front of the top cover applies pressure to the deco panel, thereby stably coupling the deco hanger of the deco panel and restricting the movement of the locking bar, thereby reducing the possibility of the locking bar moving during the process of opening and closing the door and reducing the possibility of the deco panel being easily detached.

[0057] In addition, the present disclosure has the advantage that the user can easily replace the control cover because the control cover is easily attached to and detached from the control panel through a panel locking part that applies elastic force.

[0058] Furthermore, the present disclosure allows for the replacement of both the door's decorative panel and the control panel's cover, which constitute the surface exposed to the user, when the user wishes to replace them with panels of a desired design or color. Therefore, there is an advantage in being able to pursue design consistency desired by the user.

[0059] In addition, since both the door's deco panel and the control panel's cover are replaceable, the present disclosure offers the advantage of being convenient for maintaining the internal structure of the door or control panel, and also offers the advantage of being easier to replace because space is secured to insert a finger or tool to replace the control cover when the door is open.

[0060] In addition, the present disclosure has a sloped structure in which the thickness of the deco support increases toward the bottom, thereby strengthening the fastening force as the deco panel descends due to its own weight, resulting in a firm and secure adhesion.

[0061] In addition, the present disclosure has the effect of fundamentally blocking the possibility of unlocking due to vibration during the product's service life, as the top cover equipped with a locking pin physically restricts the movement of the locking bar.

[0062]

[0063] In addition, the present disclosure has the advantage that the head of the height adjustment screw is exposed inside the case and a handle for user convenience is formed on the head, allowing the user to easily adjust the height by opening the door without taking out the already built-in cooking appliance.

[0064] In addition, the present disclosure has the advantage of preventing the aesthetic appearance of the product from deteriorating when the door is opened by concealing the area where the height adjustment screw is installed by means of a concealed cover.

[0065] In addition, the present disclosure has the advantage that when the door is opened, a hidden cover is pulled out to cover the height adjustment screw, and the user can remove the upper part of the hidden cover and operate the height adjustment screw, so that when the door is opened, the height adjustment screw is automatically hidden, and when height adjustment is required, the user can remove the upper part of the hidden cover and adjust it.

[0066] In addition, the present disclosure has the advantage of preventing the aesthetic appearance of the product from being degraded when the door is opened by concealing the area where the hinge pivot connector and the wire harness are installed by means of a concealed cover.

[0067] In addition, the present disclosure has the advantage of reducing the number of parts by concealing the hinge pivot connector, wire harness, and height adjustment screw through a concealment cover, thereby preventing the accumulation of foreign substances such as oil generated from food cooked in the cooking space, and concealing them with a single concealment cover instead of concealing each component separately.

[0068] In addition, the present disclosure has the advantage of improving user convenience by allowing cleaning of height adjustment screws, etc., to be performed by removing only a part of the detachable moving cover among the concealed covers.

[0069] In addition, the present disclosure has a design advantage in that the concealed cover can be simply installed without a separate driving source by moving the concealed cover in conjunction with the opening and closing of the door by means of an elastic member.

[0070] The effects of the present disclosure are not limited to those mentioned above, and other unmentioned effects will be clearly understood by those skilled in the art from the description in the claims.

[0099] The advantages and features of the present disclosure and the methods for achieving them will become clear by referring to the embodiments described below in detail together with the accompanying drawings. However, the present disclosure is not limited to the embodiments disclosed below but may be implemented in various different forms. These embodiments are provided merely to ensure that the disclosure is complete and to fully inform those skilled in the art of the scope of the invention, and the present disclosure is defined only by the scope of the claims. Throughout the specification, like reference numerals refer to like components.

[0100] Hereinafter, the present disclosure will be described with reference to drawings for explaining a cooking appliance (1) according to one embodiment of the present disclosure.

[0101] FIG. 3 is a perspective view showing a cooking device according to one embodiment of the present invention, and FIG. 4 is an exploded perspective view showing the cooking device of FIG. 3.

[0102] Referring to FIGS. 1 and 2, a cooking device (100) according to one embodiment of the present disclosure includes a casing (110) that forms an exterior. A cavity (S) capable of cooking food is provided inside the casing (110). The casing (10) may be formed with an open front surface.

[0103] The cavity (S) forms a cooking chamber where a user can cook food. The cavity (S) forms a roughly cuboidal space and may include sides forming the left and right sides of the cooking chamber, an upper surface forming the upper side, a lower surface forming the bottom side, and a rear surface forming the rear side. Through the open front of the casing (110), the user can introduce food for cooking into the cavity (S).

[0104] A cooking device (100) according to one embodiment of the present disclosure may further include a door (120) that opens and closes a cavity (S) with respect to a casing (110) by rotating a hinge-connected pivot member (200), as referenced in FIGS. 1 and 2. The door (120) closes the cavity (S) while covering the open front of the casing (110) and opens the cavity (S) while being spaced apart from the front of the casing (110).

[0105] The door (120) may be provided with a combination of a fixed frame (121), at least one decorative panel, and a door top cover. Of course, the door (120) may further include at least one inner door panel (129).

[0106] A deco panel can be detachably attached to the front of the fixed frame, and an inner door panel (129) can be attached to the rear of the fixed frame.

[0107] The door (120) may further include a door handle (not shown) to facilitate opening and closing by the user. The door handle may be formed on the front of the door top cover. More preferably, the door handle may be provided on the upper side of the deco panel.

[0108] However, the door (120) does not necessarily need to be equipped with a door handle. For example, as referenced in FIG. 4, the door (120) may further include a contact sensor attached to the back of the door top cover. When the closed state of the door (120) is detected by the contact sensor, the opening of the cavity (S) can be rotated in a one-touch manner according to the pressure applied by the user pushing the front of the door (120).

[0109] The detailed structure of the door (120) is described below in FIG. 16.

[0110] The door (120) serves to open and close the cavity (S) of the casing (110). To this end, a hinge installation part (not indicated in the drawing) in which a hinge pivot connector (130), described later, is installed may be provided at the lower front part of the casing (110). The hinge installation part may be formed one each at the lower left and lower right parts of the front part of the casing (110). The door (120) can open and close the cavity (S) in a pull-down manner in which the upper part rotates up and down around its lower part.

[0111] The hinge pivot connector (130) can be coupled to the hinge connection part (1217) of the fixed frame.

[0112] Meanwhile, a control panel (430) that displays the operating status of the cooking appliance (1) and controls its operation may be mounted on the front upper part of the casing (110). The control panel (430) may be provided as a touch panel. The control panel (430) may include an input section that controls its operation by capacitive touch input. The control panel (430) may be electrically connected through a pair of signal connection terminals (not shown) to receive electrical signals from the casing (110) side.

[0113] A control cover that covers the control panel can be attached to and detached from the front of the control panel. A panel catch is installed on the control cover, and the panel catch engages with the control panel to secure the control cover to the control panel. The detailed coupling structure of the panel catch is described later in FIG. 26.

[0114] In addition, when the aforementioned lighting module is provided inside the door (120), the cooking device (1) according to one embodiment of the present invention may further include a wire harness (refer to reference numeral '140' in FIG. 8a and FIG. 8b described later) for supplying power to the lighting module. The wire harness (140) is configured to be hidden from view by the concealed cover (200) described later.

[0115] A cooking device (1) according to one embodiment of the present disclosure further includes a concealed cover (200) that is withdrawn from the cavity (S) side when the door (120) is opened and is drawn into the cavity (S) side when the door (120) is closed, as referenced in FIGS. 3 and 4.

[0116] The concealed cover (200) is withdrawn from the cavity (S) side when the door (120) is opened and is retracted into the cavity (S) side when the door (120) is closed to always cover the hinge pivot connector (130).

[0117] Additionally, the concealed cover (200) can cover a portion of the bottom of the door (120) when the door (120) is open. The concealed cover (200) can be positioned so as not to overlap with the door (120) in the vertical direction when the door (120) is closed. The concealed cover (200) is positioned to overlap with the door (120) in the horizontal direction when the door (120) is closed.

[0118] Specifically, the concealment cover (200) can cover a portion of the bottom of the deco panel when the door (120) is opened.

[0119] And, when the door (120) is opened, the concealed cover (200) is pulled out from the cavity (S) side to cover the height adjustment screw, and when the door (120) is closed, it is pulled in to the cavity (S) side to expose a part of the height adjustment screw.

[0120] When the above door is closed, the above concealed cover is positioned in a location that does not overlap with the height adjustment screw in the vertical direction.

[0121] When the above door is closed, the door is positioned to overlap with at least a part of the height adjustment screw in the vertical direction.

[0122] FIG. 5 is a perspective view showing the hidden cover among the configurations of FIG. 3, and FIG. 6 is an exploded perspective view showing the moving cover among the configurations of the hidden cover of FIG. 5.

[0123] As referenced in FIGS. 5 and 6, the concealed cover (200) may include a fixed cover (210) fixed to a casing (110) and having a hollow (211) that is open at the front and back, and a moving cover (220) that moves under the guidance of the fixed cover (210).

[0124] The fixed cover (210) is formed in a roughly rectangular frame shape, and a hollow (211) may be formed in a rectangular shape inside. The hollow (211) of the fixed cover (210) may be formed to be open in the front-rear direction. Here, the hollow (211) of the fixed cover (210) may have a shape corresponding to the outer surface of the part with the largest vertical cross-sectional area among the moving cover (220).

[0125] The fixed cover (210) can be fixed to the casing (110). The fixed cover (210) can be fixed to the bottom of the casing (110). Specifically, the fixed cover (210) can be fixed to a guide frame (refer to the reference numeral '150' in FIGS. 8a and 8b described later) provided at the bottom of the front end of the casing (110). While fixed to the guide frame (150), the fixed cover (210) performs the function of guiding the moving cover (150) to slide forward and backward through the hollow (211).

[0126] As referenced in FIG. 5, the moving cover (220) may have a concealed space (225, 226) formed therein to conceal the hinge pivot connector (130) and the wire harness (140) inside. The concealed space (225, 226) may be formed to communicate in the front-rear direction of the moving cover (220).

[0127] Additionally, the moving cover (220) may be provided as a combination of a lower cover (222) and an upper cover (221). The lower cover (222) occupies the lower part of the hidden space (225, 226) and performs a sliding movement in accordance with the guidance of the fixed cover (210).

[0128] The upper cover (221) occupies the upper part of the concealed space (225, 226) and can be detachably coupled to the lower cover (222). A plurality of hook protrusions (229a) are formed on the inner surface of the upper cover (221), and a plurality of hook coupling grooves (229b) into which the plurality of hook protrusions (229a) are hook-hooked can be formed on the inner surface of the lower cover (222).

[0129] Here, the upper cover (221) may be provided with specifications of various heights to change the upper and lower heights of the hidden space (225, 226). For example, since the volume occupied by the hinge pivot connector (130) and wire harness (140) (or the height adjustment screw (180) described later) which are placed and hidden inside the hidden space (225, 226) varies from product to product, the upper cover (221) may be replaced and installed on the lower cover (222) to correspond to the upper and lower heights of the hidden space (225, 226). However, since the moving cover (220) is configured to be guided through the hollow (211) of the fixed cover (210), it is preferable that it be provided with specifications of various heights corresponding to the upper and lower heights of the hidden space (225, 226) changed by replacing the upper cover (221).

[0130] A pair of guide ends (227) may be integrally formed in the moving cover (220). More specifically, a pair of guide ends (227) may be formed at the rear end of the lower cover (222) of the moving cover (220). A pair of guide ends (227) may be formed extending in the moving direction of the moving cover (220) from the rear end of the moving cover (220). That is, a pair of guide ends (227) may be formed extending in the front-rear direction from the rear end of the moving cover (220). A first guide slot (228) cut in the left-right direction may be formed on the inner side of a pair of guide ends (227). A pair of guide ends (227) may be arranged at a predetermined distance apart in the left-right direction from the rear end of the moving cover (220).

[0131] A second guide slot (223) may be formed in the moving cover (220). More specifically, the second guide slot (223) may be formed on the inner bottom surface of the lower cover (222) of the moving cover (220). The second guide slot (223) may be formed by cutting into the bottom surface of the lower cover (222), extending in the moving direction (i.e., front-back direction) of the lower cover (222), and may be formed by cutting into the up-and-down direction. The second guide slot (223) may be formed by cutting a predetermined distance from the front end of the inner bottom surface of the lower cover (222) toward the rear.

[0132] Meanwhile, a limit projection (213) that is inserted into the interior of the second guide slot (223) may be formed on the fixed cover (210). By being inserted into the interior of the second guide slot (223), the limit projection (213) prevents the forward removal of the moving cover (220) by engaging with the rear end of the second guide slot (223) when the lower cover (222) slides forward.

[0133] FIG. 7 is a partial side perspective view taken in the direction of “B” of FIG. 3, FIG. 8a and FIG. 8b are cutaway perspective views taken along line AA of FIG. 3, showing the door closed (a) and the door open (b), FIG. 9a and FIG. 9b are side cross-sectional views taken along line CC of FIG. 3, showing the door closed (a) and the door open (b).

[0134] In a cooking appliance (1) according to one embodiment of the present disclosure, as referenced in FIGS. 8a to 9b, a hinge pivot connector (130) for pull-down pivot opening and closing of the casing (110) may be connected to the door (120).

[0135] The hinge pivot connector (130) may be positioned in the spaced-out space between the deco panel and the inner door panel (129) in the configuration of the door (120). The front end (131) of the hinge pivot connector (130) may be partially exposed to the lower portions of the deco panel and the inner door panel (129) and may be hinge-coupled to the casing (110). Preferably, the front end of the hinge pivot connector (130) may be hinge-coupled to the front end side of a guide frame (150) that is provided long in the front-rear direction on both the left and right sides of the lower front end of the casing (110).

[0136] Here, the leading edge (131) of the hinge pivot connector (130) can be concealed from the outside by being located in the concealed space (225, 226) of the moving cover (220) that is pulled forward when the door (120) is opened. The leading edge (131) of the hinge pivot connector (130) may be a part that is always in contact with the moving cover (220) when the door (120) is opened or when the door (120) is closed.

[0137] Such a hinge pivot connector (130) may be provided at both left and right ends of the door (120). That is, at the lower portions of both left and right ends of the front end of the casing (110), an installation portion may be provided for hinge-connecting the front end (131) of the hinge pivot connector (130), and a guide frame (150) may be arranged in the front and rear directions at the installation portion.

[0138] Meanwhile, a cooking device (1) according to one embodiment of the present disclosure may further include a height adjustment screw (180) provided at the lower end of a casing (110), as referenced in FIGS. 8a to 9b. The height adjustment screw (180) may be provided at the lower end of the front portion of the casing (110). More specifically, the height adjustment screw (180) may be installed to penetrate the lower front portion of the casing (110) where a front panel (112) covering the space between the casing (110) and the cavity (S) and a base panel (160) forming the lower surface of the casing (110) are joined.

[0139] The height adjustment screw (180) is provided with a head for height adjustment at the top, and the head of the height adjustment screw (180) is positioned in the hidden space (225, 226) of the moving cover (220) described above so as to be hidden from the outside.

[0140] Here, the hidden space (225, 226) formed in the moving cover (220) can be divided into a first hidden space (225) where a part of the height adjustment screw (180) described above is located, as referenced in FIGS. 5 and 6, and a second hidden space (226) where the tip (131) of the hinge rotation connector (130) described above is located.

[0141] As described above, a second guide slot (223) is formed on the bottom surface of the lower cover (222) corresponding to the first concealed space (225), so that the height adjustment screw (180) fixed to the casing (110) is not interfered with when the lower cover (222) slides in the forward and backward directions.

[0142] Additionally, the second guide slot (223) is a space into which a part of the height adjustment screw (180) is inserted.

[0143] Additionally, the bottom surface of the lower cover (222) corresponding to the second hidden space (226) is partially cut so as not to interfere with the rotation of the hinge rotation connector (130), and a round groove (224) having a rounded vertical cross-section may be formed on the upper part of the upper cover (221) corresponding to the second hidden space (226) to prevent the moving cover (220) from being lifted by the leading edge (131) of the hinge rotation connector (130). The round groove (224) may be formed with a rounded surface such that the moving cover (220) in contact is not lifted upwards, taking into account the rotational trajectory of the leading edge (131) of the hinge rotation connector (130).

[0144] However, the prevention of the lifting phenomenon of the moving cover (220) by the rotational movement of the leading edge (131) of the hinge rotational connector (130) is not necessarily achieved only by the round groove (224) of the moving cover (220). For example, the leading edge (131) of the hinge rotational connector (130) can also be designed so that contact with the moving cover (220) is made without interference.

[0145] Meanwhile, a cooking device (1) according to one embodiment of the present disclosure may include a guide frame (150) positioned on the lower side of the front end of the casing (110) to guide the forward and backward sliding movement of the moving cover (220), as referenced in FIGS. 8a to 9b.

[0146] A fixed cover (210) may be fixed to the guide frame (150), and a front end (131) of a hinge pivot connector (130) may be hinge-coupled to a front end further forward than the guide frame (150). Additionally, a case guide projection (117) that is inserted into the interior of the first guide slot (128) described above may be provided at the rear end of the guide frame (150).

[0147] The case guide projection (117) is inserted and positioned inside the first guide slot (128) to guide the forward and backward sliding movement of the moving cover (220), and also serves to limit the forward and backward sliding movement range of the moving cover (220) within the forward and backward length direction of the first guide slot (128).

[0148] Meanwhile, in a cooking device (1) according to one embodiment of the present disclosure, the moving cover (220) slides in the forward and backward directions relative to the fixed cover (210), and can be moved by the expansion and restoring force of the elastic member (230).

[0149] The elastic member (230) may be provided inside the lower front portion of the casing (110), as referenced in FIGS. 9a and 9b. Here, the elastic member (230) may be provided as a spring. The elastic member (230) provided as a spring may have one end (231) connected to a fixed cover (210) and the other end (232) connected to a moving cover (220).

[0150] Such an elastic member (230) can be expanded by a moving cover (220) that slides backward and is inserted into the casing (110) by contact with the front end (131) of the hinge pivot connector (130) when the cavity (S) of the door (120) is closed.

[0151] Conversely, the elastic member (230) can slide the moving cover (220) forward to be pulled out of the casing (110) while forming a restoring force that expands when the cavity (S) of the door (120) opens and then contracts. That is, the moving cover (220) can be moved in conjunction with the door (120) by having its front end constantly in contact with the front end (131) of the hinge rotation connector (130) of the door (120) according to the expansion and restoring force of the elastic member (230).

[0152] However, the elastic member (230) does not necessarily have to be provided as a spring, and may be provided as a torsion bar spring, although not shown. The elastic member (230) provided as a torsion bar spring may be provided such that the expansion and restoring forces described above are formed by connecting one end to a fixed body (210) or guide frame (150) in a fixed state and connecting the other end to a moving cover (220).

[0153] In this way, the cooking device (1) according to one embodiment of the present disclosure can be simplified internally by being configured to automatically be withdrawn and inserted from the casing (110) in conjunction with the opening and closing rotation of the door (120) according to the expansion and restoring force of the elastic member (230) without having to provide a separate power source for the sliding movement of the moving cover (220).

[0154] Meanwhile, a sealing member (190) may be further provided in the portion of the front section of the casing (110) where the front portion of the door (120) frame (121) of the door (120) is in close contact. The sealing member (190) may be made of a flexible material such as rubber or silicone, and performs the function of sealing the cavity (S), which is the cooking chamber, when compressed by the door (120) frame (121) or the door (120) top cover.

[0155]

[0156] Hereinafter, the operation of a cooking device (1) according to one embodiment of the present disclosure configured as above will be described.

[0157] First, as referenced in FIG. 9a, when the cavity (S) is closed using the door (120), the front end (131) of the hinge rotation connector (130) linked to the door (120) comes into contact with the moving cover (220) and moves it backward. At this time, the moving cover (220) can slide and move naturally into the interior of the casing (110) while being guided by the guide frame (150) along with the guide of the fixed cover (210), so as to prevent it from being lifted upward. Additionally, the elastic member (230) expands as the moving cover (220) moves into the interior of the casing (110) and continuously provides an elastic force forward.

[0158] Next, as referenced in FIG. 9b, when the cavity (S) is opened and rotated using the door (120), the moving cover (220) is stopped inside the casing (110) by the hinge rotation connector (130) of the door (120), and is pulled forward from inside the casing (110) by the restoring force of the elastic member (230), thereby receiving the tip (131) of the hinge rotation connector (130), the wire harness (140), and the upper part of the height adjustment screw (180) into the hidden space (225, 226) to conceal them from the outside.

[0159] In this way, the cooking device (1) according to one embodiment of the present disclosure can prevent the aesthetic appearance of the product from being degraded by using a moving cover (220) to conceal components such as a hinge pivot connector (130), a wire harness (140), and a height adjustment screw (180) from the outside when the door (120) is opened.

[0160] In addition, even when the door (120) is closed, foreign substances such as oil generated from food in the cooking chamber can be induced to accumulate only on the outer surface of the moving cover (220), thereby improving the user's cleaning convenience.

[0161]

[0162] Below, the height adjustment screw (180) is described in detail.

[0163] FIG. 10 is a perspective view showing the casing (110) and the height adjustment screw (180) with the exception of other configurations in FIG. 3.

[0164] The casing (110) may include an opening (110a) that is open in one direction. Specifically, the casing (110) has an opening (110a) that is open forward, and has a structure that is closed in the other direction.

[0165] More specifically, the casing (110) may include an upper surface (111) and a lower surface (160) facing each other, two side surfaces (114, 116) connecting the upper surface (111) and the lower surface (160) facing each other, and a rear surface (118) connecting the upper surface (111) and the lower surface (160) and the two side surfaces (114, 116).

[0166] Additionally, the casing (110) may be formed as a single unit or may be formed by combining several segments.

[0167] For example, as illustrated in FIG. 10, the casing (110) may include a base panel (160) forming the lower surface of the casing (110) and an upper panel (170) forming the upper surface and side surface of the casing (110).

[0168] The casing (110) includes a front panel (112) that covers the space between the casing (110) and the cavity (S). The front panel (112) may define a surface that intersects the front and rear directions. The front panel (112) may have an opening (112a) formed therein that corresponds to the opening (110a) of the casing (110).

[0169] The front panel (112) may be attached to the upper surface or the front side of the casing (110), but it is preferable to attach it to the base panel (160).

[0170] For example, the front panel (112) may further include a panel joining portion (1121) that is joined to the base panel (160). The panel joining portion (1121) may define a surface that intersects the front panel (112) and a surface that is parallel to the base panel (160). The panel joining portion (1121) creates surface contact between the front panel (112) and the base panel (160). The front panel (112) may be joined to the front end of the base panel (160).

[0171] Additionally, the front panel (112) may include a harness hole (112b) for accommodating a concealed cover (200). The harness hole (112b) may be positioned on the left and right sides of the bottom of the front panel (112), respectively. The harness hole (112b) provides a movement space when the concealed cover (200) is moved back and forth. The harness hole (112b) may be formed by penetrating the front panel (112) in the front and rear directions.

[0172] Additionally, a portion of the hinge pivot assembly (130) and the wire harness (140) is located inside the harness hole (112b).

[0173] It is preferable that the height adjustment screw (180) be installed in a position where it can be easily adjusted by the user when the door (120) is open.

[0174] For example, the height adjustment screw (180) can be attached to one side of the casing (110) adjacent to the edge of the opening of the casing (110). Specifically, the height adjustment screw (180) can be attached to a base panel (160) corresponding to the lower surface of the casing (110).

[0175] As another example, the height adjustment screw (180) can be attached to the front panel (112). Specifically, the height adjustment screw (180) can be attached to the panel joining portion (1121) of the front panel (112). A first screw hole (112c) in which the height adjustment screw (180) is installed is formed in the panel joining portion (1121).

[0176] As another example, the height adjustment screw (180) can be connected to the front panel (112) and the base panel (160). The height adjustment screw (180) can be connected by penetrating the front panel (112) and the base panel (160).

[0177]

[0178] FIG. 11a is a perspective view showing the height adjustment screw (180) and the concealed cover (200) in the configuration of FIG. 3, FIG. 11b is a drawing showing the operation of the height adjustment screw (180) of FIG. 11a, FIG. 12 is a cross-sectional view showing the height adjustment screw (180) of FIG. 11a and the surrounding area, FIG. 13 is a drawing showing, in order, a perspective view, a side view, a front view, a front cross-sectional view, and a side cross-sectional view of another height adjustment screw (180) and a wire harness (140) in one embodiment of the present disclosure.

[0179] Referring to FIGS. 11 to 13, the height adjustment screw (180) adjusts the installation height of the casing (110). Additionally, the height adjustment screw (180) is screw-coupled to the casing (110) to adjust the distance between the bottom surface (B) and the casing (110).

[0180] For example, part of the height adjustment screw (180) may be located inside the casing (110), and other part may be located outside the casing (110).

[0181] Specifically, the height adjustment screw (180) may include a screw leg (183), a screw head (181), and a screw body (182).

[0182] The screw leg (183) is located outside the casing (110). The screw leg (183) supports the weight of the casing (110) and the cooking appliance. The screw leg (183) may have an expanded outer diameter or cross-sectional area compared to the screw body (182).

[0183] The screw body (182) connects the screw leg (183) and the screw head (181), penetrates the casing (110), and has screw threads (184) formed on its outer surface. The screw body (182) can be inserted into the second screw hole (160a) and / or the first screw hole (112c) of the base panel (160).

[0184] The screw head (181) is located inside the casing (110). The screw head (181) may have an expanded outer diameter or cross-sectional area compared to the screw body (182).

[0185] The screw head (181) may have a structure that facilitates the transmission of external force to the user to rotate the height adjustment screw (180).

[0186] A head handle (187) that enhances grip strength may be formed on the screw head (181). If the screw head (181) is in the shape of a disc, the head handle (187) may have a shape that protrudes upward from the upper surface of the screw header and extends in one direction intersecting the up and down direction. The head handle (187) enhances the user's grip strength, allowing the user to easily rotate the height adjustment screw (180) with less force.

[0187] Additionally, a screw body (182) may be inserted into the casing (110), and a nut (185) with threads formed on its inner surface may be installed.

[0188] A nut groove (112d) for receiving a nut (185) is formed around at least one of the first screw hole (112c) and the second screw hole (160a). Specifically, the nut groove (112d) may be formed by the panel joint portion (1121) of the front panel (112) being recessed downward. The nut groove (112d) may be positioned to surround the first screw hole (112c).

[0189] When the height adjustment screw (180) is installed alone in the casing (110), it may encroach upon the space for installing other parts or interfere with other parts.

[0190] Therefore, it is preferable that the height adjustment screw (180) be installed by passing through the wire harness (140).

[0191] Specifically, the screw head (181) and screw leg (183) of the height adjustment screw (180) are located outside the wire harness (140), and a part of the screw body (182) may be located inside the wire harness (140).

[0192] Below, the detailed structure of the wire harness (140) to which the height adjustment screw (180) is attached is described.

[0193] The wire harness (140) may include a body hole (144) through which a screw body (182) passes, and a head groove (143) into which a screw head (181) is seated.

[0194] The body hole (144) may be a hole that penetrates the wire harness (140) vertically. The head groove (143) may be positioned to overlap the body hole (144) in a vertical direction.

[0195] The head groove (143) has a larger cross-sectional area than the body hole (144), so that the downward movement of the screw head (181) can be restricted. Additionally, the head groove (143) forms a space for accommodating the screw head (181). The head groove (143) can be formed by the upper surface of the wire harness (140) being recessed downward.

[0196] For example, the wire harness (140) may include a first harness (141) connected to the door (120) and a second harness (142) hinged to the first harness (141) and connected to the casing (110).

[0197] If the wire harness (140) includes a first harness (141) and a second harness (142) that are hinged together, the first harness (141) and the second harness (142) rotate around the hinge (149) when the door (120) rotates.

[0198] The first harness (141) has a first wire hole (147) through which a wire passes. The second harness (142) has a second wire hole (145) through which a wire passes. The first wire hole (147) is in communication with the second wire hole (145).

[0199] The body hole (144) and the head groove (143) described above may be formed in the second harness (142). The body hole (144) may be installed by penetrating the second wire hole (145). The body hole (144) may extend in a direction intersecting the second wire hole (145).

[0200] Specifically, the body hole (144) can be extended in the vertical direction, and the second wire hole (145) can be extended in the forward and backward direction.

[0201] The head groove (143) can be formed by the upper surface of the second harness (142) being sunk downward.

[0202]

[0203] A portion of the height adjustment screw (180) can be located in the first concealed space (225) of the moving cover (220) and concealed from the outside.

[0204] Here, the expressions of being concealed or covered mean that a part of the height adjustment screw (180) is not visible from the user's field of vision, and that the concealment cover (200) covers a part of the height adjustment screw (180) at least from the top.

[0205] Preferably, the expressions of being concealed or covered may mean that the concealed cover (200) covers a part of the height adjustment screw (180) from the top and wraps around the side of a part of the height adjustment screw (180).

[0206] Specifically, a portion of the screw head (181) and screw body (182) of the height adjustment screw (180) may be located in the first concealed space (225).

[0207] The lower part of the first concealed space (225) is open or partially open so that when the moving cover (220) moves back and forth, it does not interfere with the screw body (182).

[0208] Specifically, the screw body (182) is inserted into the second guide slot (223) formed in the lower part of the first concealed space (225). When the moving cover (220) moves back and forth, the screw body (182) moves within the second guide slot (223).

[0209] Accordingly, the present disclosure prevents foreign substances, such as oil generated from food cooked in the cooking space, from accumulating by concealing the hinge pivot connector (130), wire harness (140), and height adjustment screw (180) through the concealment cover (200), and since each component is concealed with one concealment cover (200) instead of being concealed separately, the number of parts can be reduced.

[0210] In addition, the present disclosure improves user convenience by allowing cleaning of height adjustment screws (180), etc., to be performed by removing only a part of the detachable moving cover (220) among the concealed covers (200).

[0211] Specifically, when the user opens the door (120), the moving cover (220) moves forward so that the upper cover (221) of the moving cover (220) is exposed into the space inside the casing (110).

[0212] The height adjustment screw (180) is covered by the upper cover (221). When the user removes the upper cover (221), a part of the height adjustment screw (180) (screw head (181)) is exposed. The user can adjust the position of the cooking appliance by adjusting the exposed height adjustment screw (180).

[0213]

[0214] Hereinafter, the operation of the height adjustment screw (180) will be explained with reference to FIGS. 11a and FIGS. 11b.

[0215] In the state of Fig. 11a, if the user wants to raise the height of the casing (110) or the cooking appliance, they hold the head handle (187) and rotate the screw head (181) in one direction (clockwise), and the height adjustment screw (180) moves downward relative to the casing (110) due to the interaction between the screw thread (184) and the nut (185).

[0216] The height adjustment screw (180) moved downward causes the distance between the screw leg (183) and the casing (110) to increase, and consequently, the distance between the bottom surface (B) and the bottom of the casing (110) increases.

[0217] Of course, if the user wants to raise the height of the casing (110) or the cooking appliance, contrary to the above description, they can simply hold the head handle (187) and rotate the screw head (181) counterclockwise.

[0218]

[0219] FIG. 14 is a cross-sectional view illustrating a height adjustment screw (180) according to another embodiment of the present disclosure, and FIG. 15 is a drawing illustrating, in order, a perspective view, a side view, a front view, a front cross-sectional view and a side cross-sectional view of the height adjustment screw (180) and the wire harness (140) illustrated in FIG. 14.

[0220] Referring to FIGS. 14 and 15, the height adjustment screw (180') according to another embodiment of the present disclosure (second embodiment) has a difference in the shape of the screw head (181') compared to the embodiment of FIG. 13 (first embodiment). Hereinafter, in describing the second embodiment, the differences from the first embodiment will be described mainly, and any configurations not otherwise described will be considered identical to the first embodiment.

[0221] The screw head (181') of the second embodiment may have a smaller size than the first embodiment to reduce the space occupied. Additionally, the head handle (187) of the first embodiment may be omitted in the screw head (181') of the second embodiment.

[0222] A mechanism groove (188) may be formed in the screw head (181') to which a rotating mechanism for rotating the screw head (181') is coupled. The mechanism groove (188) is a groove to which a rotating mechanism, such as a screwdriver, is coupled, and may be a groove in which the upper surface of the screw header is recessed downward.

[0223] For example, the mechanism groove (188) may extend in at least one direction. As another example, the mechanism groove (188) may be two grooves that extend intersecting each other.

[0224] Therefore, although the user has the burden of using the rotating mechanism, if height adjustment is not performed, the possibility of interference with other components is reduced due to the smaller screw head (181'), and the space occupied by the screw head (181') is reduced.

[0225]

[0226] Below, the detailed structure of the door (120) and the detachable structure of the deco panel (127) will be described in detail.

[0227] FIG. 17 is a perspective view of the door (120) shown in FIG. 16, FIG. 18 is a rear view of the door (120) shown in FIG. 17, FIG. 19 is a side view of the door (120) shown in FIG. 17, FIG. 20 is a cross-sectional view cut along line 20-20 of FIG. 18, FIG. 21 is an exploded perspective view of the door (120) shown in FIG. 16, FIG. 22 is an exploded perspective view of the door (120) viewed from a different side from FIG. 21, FIG. 23 is a cross-sectional view cut along line 23-23 of FIG. 22, and FIG. 24 is a cross-sectional view cut along line 24-24 of FIG. 22.

[0228]

[0229] Referring to FIGS. 17 to 24, the door (120) may be provided with a combination of a fixed frame (121), at least one deco panel (127), and a door (120) top cover (123). Of course, the door (120) may further include at least one inner door panel (129) (Fig. 4) and a deco hanger (311).

[0230] A deco panel (127) can be detachably attached to the front of the fixed frame (121), and an inner door panel (129) can be attached to the rear of the fixed frame (121).

[0231] The fixed frame (121) reveals the interior of the cavity through the deco panel (127) and the inner door panel (129), and further includes a central hole (1211) to reduce material costs. The fixed frame (121) may be formed in the shape of a square frame that encloses the central hole (1211).

[0232] The fixed frame (121) can be introduced into the inner side of the front edge of the casing (110) when the cavity (S) is closed by the door (120) and can be in close contact with the sealing member (190) of the casing (110). When the fixed frame (121) is in close contact with the sealing member (190), the front surface can be matched with the front edge surface of the casing (110).

[0233] The fixed frame (121) can be rotatably coupled to the casing (110). The bottom of the fixed frame (121) may be provided with a hinge connection part (1217) to which a hinge pivot connector (130) is coupled.

[0234] Specifically, the fixed frame (121) may include an inner frame (1213) that surrounds a central hole (1211) and a side frame (1214) that is attached to at least one outer surface of the inner frame (1213) to facilitate the connection of the deco panel (127) and maintain rigidity.

[0235] The inner frame (1213) is shaped like a plate and surrounds the central hole (1211). A connecting hole (1212) (1212) through which the deco hanger (311) passes is formed in the inner frame (1213).

[0236] The side frame (1214) reinforces the rigidity of the inner frame (1213) and prevents the inner frame (1213) from bending. The side frame (1214) may have a thicker thickness than the inner frame (1213) or a larger front-to-back width.

[0237] The side frame (1214) extends in the vertical direction and can be connected to both left and right ends of the inner frame (1213). The hinge connection part (1217) is connected to the side frame (1214) so ​​that the rigidity of the door (120) can be maintained when the door (120) is opened and closed.

[0238] The coupling hole (1212) is a hole formed by penetrating the fixed frame (121). It is preferable that the coupling hole (1212) be formed in the inner frame (1213) of the fixed frame (121) which has a thinner thickness.

[0239] Multiple coupling holes (1212) may be installed. Multiple coupling holes (1212) may be arranged symmetrically with respect to the central hole (1211). The coupling holes (1212) may be arranged on the left and right sides of the inner frame (1213).

[0240] It is preferable for the stability of the connection that two connection holes (1212) are arranged side by side adjacent to the top of the inner frame (1213), and two connection holes are arranged side by side adjacent to the bottom of the inner frame (1213).

[0241] The coupling hole (1212) has a shape corresponding to the shape of the deco hanger (311). Specifically, the coupling hole (1212) is rectangular. The coupling hole (1212) has a smaller size than the central hole (1211).

[0242] The fixed frame (121) may include a deco support (1216) on which the deco hanger (311) is hung. In particular, referring to FIG. 24, one end of the deco support (1216) is connected to a coupling hole (1212), and is an area on which the deco hanger (311) passing through the coupling hole (1212) is hung.

[0243] The deco support (1216) can be defined as a portion of the inner frame (1213) that surrounds the coupling hole (1212). Specifically, the deco support (1216) is a portion of the inner frame (1213) located below the coupling hole (1212).

[0244] The thickness of the deco support (1216) can increase as it moves further away from the coupling hole (1212). Specifically, the front-to-back thickness of the deco support (1216) can increase from the top to the bottom. Therefore, when the deco hanger (311) that has passed through the coupling hole (1212) moves downward and is caught on the deco support (1216), the fastening is made easier, while the fastening force is strengthened during fastening.

[0245] Additionally, the front of the deco support (1216) may be recessed further back than the front of the inner frame (1213). The front of the deco support (1216) provides a space where the bracket (310) of the deco hanger (311) is positioned.

[0246] Even if the deco panel (127) is hung by passing through the coupling hole (1212) by the deco hanger (311), it is supported by the self-weight of the deco panel (127), so the deco panel (127) may shake or the coupling of the deco panel (127) may be easily released.

[0247] Accordingly, the door (120) may further include a locking bar (124). In particular, referring to FIG. 18, the locking bar (124) is slidably installed on a fixed frame (121) to optionally restrict the movement of the deco hanger (311).

[0248] The locking bar (124) is installed on the rear of the fixed frame (121). When the locking bar (124) is installed on the rear of the fixed frame (121), the locking bar (124) is not exposed to the outside when the door (120) is closed.

[0249] A slider (1215) on which a locking bar (124) slides may be formed in the fixed frame (121). The slider (1215) extends in a horizontal direction and guides the locking bar (124) to reciprocate in a horizontal direction.

[0250] Specifically, the slider (1215) may be positioned at one end adjacent to the coupling hole (1212) on the rear side of the fixed frame (121). Additionally, the slider (1215) may be positioned such that the height of the locking bar (124) when moved is equal to the height of the coupling hole (1212). More specifically, the slider (1215) is positioned on the rear side of the inner frame (1213).

[0251] The locking bar (124) may have a size sufficient to cover the coupling hole (1212). When a part of the locking bar (124) covers the coupling hole (1212), another part of the locking bar (124) is positioned on the slider (1215). The length of the locking bar (124) may be longer than the length of the coupling hole (1212). This is because the slider (1215) cannot extend to the bottom of the coupling hole (1212) due to the space where the deco hanger (311) is hung.

[0252] The locking bar (124) may include a first bar (1241, FIG. 25) and a second bar (1243, FIG. 25) having a thicker thickness than the first bar (1241). The first bar (1241) is positioned closer to the coupling hole (1212) than the second bar (1243). The second bar (1243) may have a protruding area than the first bar (1241). When the user moves the locking bar (124), the second bar (1243) acts as a handle or increases friction with the locking pin (1233) described later.

[0253] When the locking bar (124) is in a locked state, it covers the coupling hole (1212) and is positioned to overlap with the deco hanger (311) in the vertical direction. The locking bar (124) covering the coupling hole (1212) means that a part of the locking bar (124) and the coupling hole (1212) are positioned to overlap in the vertical direction. When the locking bar (124) is in a locked state, it is positioned on the upper part of the deco hanger (311) to prevent the deco hanger (311) from moving upward and detaching from the coupling hole (1212).

[0254] When the locking bar (124) is in an open state, it exposes the coupling hole (1212) and is positioned so as not to overlap with the deco hanger (311) in the vertical direction. The locking bar (124) exposing the coupling hole (1212) means that the locking bar (124) and the coupling hole (1212) are positioned so as not to overlap in the vertical direction. When the locking bar (124) is in an open state, the deco hanger (311) can move upward, and the deco hanger (311) can pass through the coupling hole (1212) so that the deco panel (127) can be separated from the fixed frame (121).

[0255] Additionally, a limit projection (1218) that limits the horizontal movement of the locking bar (124) may be formed on the fixed frame (121).

[0256] The door (120) may further include a top cover (123) that is detachable from the top of the fixed frame (121).

[0257] The top cover (123) is attached to the top of the fixed frame (121) to restrict the movement of the locking bar (124) and the movement of the deco panel (127). Thus, the top cover (123) ensures that the deco panel (127) remains stably attached to the fixed frame (121). Additionally, it covers the locking bar (124) and the deco hanger (311) from the top to enhance the user's aesthetic sense.

[0258] Specifically, the top cover (123) may have a thickness greater than that of the inner frame (1213). When the top cover (123) is attached to the fixed frame (121), it may overlap the inner frame (1213) in a vertical direction. Additionally, the top cover (123) may have a thickness greater than that of the side frame (1214). When the top cover (123) is attached to the fixed frame (121), it may overlap the side frame (1214) in a vertical direction, and a portion of the top cover (123) may protrude further rearward than the side frame (1214).

[0259] The top cover (123) can be attached to the top of the inner frame (1213) and the top of the side frame (1214). The top cover (123) can be attached to the fixed frame (121) by a top hook (1232). In particular, referring to FIG. 20, the top hook (1232) can be attached to the top cover (123) in an elastically changing manner and fastened to the top of the side frame (1214).

[0260] The top cover (123) may further include an unlock button (1231) exposed on one side of the top cover (123) to move the top hook (1232) by an external force. The unlock button (1231) may be positioned on the side of the top cover (123).

[0261] The top cover (123) may further include a locking pin (1233) that restricts the movement of the locking bar (124). The locking pin (1233) contacts one side of the locking bar (124) to restrict the movement of the locking bar (124). The locking pin (1233) may extend downward from the bottom of the top cover (123). The locking pin (1233) may be positioned so as not to overlap with the inner frame (1213) in the vertical direction, and may be positioned to overlap with the inner frame (1213) in the front-rear direction.

[0262] One side of the top cover (123) may come into contact with one side of the deco panel (127). When the top cover (123) is attached to the fixed frame (121), the front side of the top cover (123) comes into contact with the rear side of the deco panel (127). The top cover (123) applies forward pressure to the deco panel (127). Thus, by restricting the movement in the forward and backward directions of the deco panel (127) fixed by the deco hanger (311), a stable connection is maintained.

[0263]

[0264] A deco panel (127) may be installed on a fixed frame (121) to cover at least the central hole (1211) of the fixed frame (121). Specifically, the deco panel (127) may cover the central hole (1211) and have a size larger than that of the fixed frame (121).

[0265] The deco panel (127) is attached to the front end of the fixed frame (121) to form the front exterior of the door (120).

[0266] The deco panel (127) may be provided with a transparent or translucent material that allows a user to observe the cavity (S) corresponding to the internal cooking chamber from the outside. Preferably, the deco panel (127) may be provided with a special material that allows the cooking chamber to be observed from the outside only when light from the lighting module illuminates the cooking chamber, provided that a lighting module (not shown) that illuminates the cooking chamber is provided.

[0267] In particular, the inner door panel (129) adjacent to the cavity (S) needs to be formed to withstand the high temperature and high pressure of the cooking chamber and needs to be equipped with waterproof and heat-insulating functions, so this can be considered in the selection of material.

[0268] Additionally, the deco panel (127) may have a transparent central part and opaque ends.

[0269] The deco hanger (311) is attached to one side of the deco panel (127) and passes through the coupling hole (1212) and hangs on the edge of the coupling hole (1212). The deco hanger (311) may have a shape that restricts movement in the forward and backward directions when it passes through the coupling hole (1212) and hangs on the edge of the coupling hole (1212). Of course, the deco hanger (311) may also be referred to as a hanger.

[0270] For example, particularly as illustrated in FIG. 23, the deco hanger (311) may have a hook shape. Specifically, the deco hanger (311) may include a first hanger part (3111) with one end connected to the deco panel (127) and a second hanger part (3112) extending downward from the other end of the first hanger part (3111). A deco support part (1216) is positioned in the space between the second hanger part (3112) and the deco panel (127).

[0271] Multiple deco hangers (311) may be arranged symmetrically with respect to the center of the deco panel (127). Specifically, deco hangers (311) may be placed on the left and right sides of the top of the deco panel (127), and on the left and right sides of the bottom of the deco panel (127).

[0272] As another example, the deco hanger (311) may have a protruding projection shape. As yet another example, the deco hanger (311) may not be directly attached to the deco panel (127) but may be attached by a bracket (310). If there are multiple deco hangers (311), the bracket (310) determines the position between them.

[0273] The bracket (310) secures a plurality of deco hangers (311) to the deco panel (127). The bracket (310) and the deco hangers (311) may be formed integrally or as separate components. The deco hangers (311) may have a protruding projection shape in addition to a hook shape.

[0274] Specifically, the bracket (310) may include a first holder (311a) and a second holder (311b) to which the deco hanger (311) is connected, and a connecting member (313) connecting the first holder (311a) and the second holder (311b). Additionally, the bracket (310) may include a connecting member (312) having a hole through which a screw connected to the deco panel (127) passes.

[0275] The connecting member (313) extends vertically, so that the connecting member (313) separates the first holder (311a) and the second holder (311b) vertically.

[0276] Since the left and right ends of the deco panel (127) are made of an opaque material, the bracket (310) can be positioned on both the left and right ends of the deco panel (127). The bracket (310) can be positioned so as not to overlap with the central hole (1211) of the fixed frame (121) in the front and rear directions. Therefore, the bracket (310) prevents the user from having the inside of the cavity obscured.

[0277]

[0278] Below, the method of attaching or detaching or replacing the deco panel (127) is described in detail.

[0279] FIG. 25 is a drawing illustrating a method of attaching and detaching a decorative panel (127) of a door (120).

[0280] Referring to FIG. 25a, first, the user opens the door (120) to expose the fixed frame (121) and the top cover (123).

[0281] Referring to FIG. 25b, the user separates the top cover (123) from the fixed frame (121) while pressing the unlock button (1231) of the top cover (123). When the top cover (123) is separated from the fixed frame (121), the force of the locking pin pressing the locking bar (124) is released, and the deco hanger (311) and the locking bar (124) are exposed to the top.

[0282] Referring to FIG. 25c, the user slides the locking bar (124) to change the locking bar (124) to an open state. When the locking bar (124) is slid, the coupling hole (1212) opens and the upper part of the deco hanger (311) opens. The user moves the deco panel (127) to the upper part to align the height of the deco hanger (311) and the coupling hole (1212), and then moves the deco panel (127) forward to separate the deco panel (127) from the fixed frame (121).

[0283] Therefore, the user can easily detach the deco panel (127) and attach another deco panel (127) of the user's choice to the fixed frame (121).

[0284] Referring to FIG. 25d, the user passes the deco hanger (311) of another deco panel (127) through the coupling hole (1212), then moves the deco hanger (311) downward to hang the deco hanger (311) at the bottom of the coupling hole (1212).

[0285] Referring to FIG. 25e, the user slides the locking bar (124) to change the locking bar (124) to a locked state. When the locking bar (124) is slid, the coupling hole (1212) is closed, and a part of the locking bar (124) is positioned on the upper part of the deco hanger (311).

[0286] Referring to FIG. 25f, the user attaches the top cover (123) to the fixed frame (121). When the top cover (123) is attached to the fixed frame (121), the locking pin presses the locking bar (124), and the deco hanger (311) and the locking bar (124) are covered by the top cover (123).

[0287] The coupling structure of the control cover (410) of the control panel (430) is described below.

[0288] FIG. 26 is a cross-sectional view taken along line 26-26 of FIG. 16.

[0289] Referring to FIG. 26, a control panel (430) that displays the operating status of the cooking appliance (1) and controls its operation may be mounted on the front upper part of the casing (110).

[0290] A control cover (410) covering the control panel (430) can be attached to the front of the control panel (430). The control cover (410) may be made of the same material as the deco panel (127). The control cover (410) may be made of a transparent material.

[0291] When a user wishes to replace panels with a design or color of their choice, both the door's decorative panel and the control panel's cover, which constitute the surfaces exposed to the user, can be replaced. This allows for the pursuit of design consistency.

[0292] In addition, since both the door's decorative panel and the control panel's cover are replaceable, there is the advantage of being convenient for maintaining the internal structure of the door or control panel. Furthermore, when the door is open, space is provided to insert fingers or tools to replace the control cover, making replacement even easier.

[0293] In the closed state of the door (120), the control cover (410) and the deco panel (127) may be spaced apart. Additionally, a partition bar (not shown) may be detachably attached between the control cover (410) and the deco panel (127).

[0294] Therefore, when replacing the control cover (410) with the door (120) closed, there is a gap between the deco panel (127) and the control cover (410) so that a finger or tool can be inserted to disassemble it. Additionally, when replacing the control cover (410) with the door (120) closed, the partition bar between the deco panel (127) and the control cover (410) can be removed, and a finger or tool can be inserted into the gap to disassemble it.

[0295] In addition, when the deco panel (127) is removed, there is a lot of space at the bottom of the control cover (410), so the control cover (410) can be replaced more easily.

[0296]

[0297] A panel catch (420) is installed on the control cover (410), and the panel catch (420) is caught on the control panel (430) so that the control cover (410) is fixed to the control panel (430).

[0298] The panel catch portion (420) may have a structure in which it is made of a material having elasticity, deformed by an external force, and restored by elasticity so as to be caught on the control panel (430).

[0299] Specifically, the control panel (430) may include at least one panel groove (432) into which a panel catch (420) is inserted, and panel protrusions (431a, 431b) located within the panel groove (432) and engaged with the panel catch (420).

[0300] More specifically, the panel hook portion (420) may include two panel hooks (421, 422) spaced apart from each other and a hook connecting portion (423) connecting the two panel hooks (421, 422). The hook connecting portion (423) is coupled to the rear surface of the control cover (410).

[0301] The two panel hooks (421, 422) can be bent in a direction that gets closer to each other as they move away from the hook connection (423).

[0302] The panel hooks (421, 422) are engaged with the panel protrusions (431a, 431b). The panel hooks (421, 422) may have an elastic restoring force in a direction that brings them closer to each other.

[0303] The control cover (410) can be easily attached to the control panel (430) by means of the panel catch (420) and can be easily detached from the control panel (430).
