[Technical Field]

[0001] The following disclosure relates to a cooking appliance. [Background technology]

[0002] For example, Patent Documents 1 and 2 disclose cooking devices for cooking food. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Patent Publication No. 2021-63621 [Patent Document 2] Japanese Patent Publication No. 2022-56123 Summary of the Invention [Problem to be solved by the invention]

[0004] In a cooking appliance, water vapor generated from cooked food condenses in the heating chamber, forming droplets. The water produced by condensation (also called condensed water) falls downward, for example, after cooking is completed. The cooking appliances described in Patent Documents 1 and 2 are equipped with a structure that directs condensed water to a water receiving member located below the main body, thereby preventing condensed water from flowing onto the installation surface of the appliance, and are extremely useful in this field. However, there is room for improvement in order to collect condensed water more intentionally.

[0005] An object of the present disclosure is to provide a cooking appliance that can intentionally collect condensation water and effectively prevent the condensation water from flowing onto, for example, the installation surface. [Means for solving the problem]

[0006] The heating cooker of the present disclosure comprises a main body having a heating chamber therein, and a door provided on the main body that closes the opening of the heating chamber in an openable and closable manner, the main body having a frame provided around the opening, the frame contacting the edge of the door-side of a side wall located on at least one of the left and right sides of the heating chamber, the door and the frame each having surfaces that can abut against each other, and a gasket arranged on the door, the gasket being arranged so that the edge, the frame and the gasket form a recess when the door is viewed in a planar state when closed. [Effects of the Invention]

[0007] The present disclosure makes it possible to provide a cooking appliance that can intentionally collect condensation water and effectively prevent the condensation water from flowing onto the installation surface, for example. [Brief explanation of the drawings]

[0009] Hereinafter, an embodiment of a cooking device 1 according to the present disclosure will be described with reference to the drawings. The present disclosure is not limited to the contents described in the following embodiments, and appropriate design changes can be made within the scope of the configuration of the present disclosure. In the drawings, identical or equivalent elements are given the same reference numerals, and duplicate explanations will be omitted. Only the main parts are shown in the drawings. The following description will focus on the main parts and parts related to the present disclosure.

[0010] In this specification, when describing directions, when the cooking appliance 1 is installed on a horizontal installation surface, the side where a user using the cooking appliance 1 is located is referred to as the front (Y1), the opposite side is referred to as the rear (Y2), the left side as seen from the user is referred to as the left side (X1), and the right side is referred to as the right side (X2). Furthermore, of the vertical directions of the cooking appliance 1 installed on a horizontal surface, the vertically upward direction is referred to as the upward direction (Z1), and the vertically downward direction is referred to as the downward direction (Z2).

[0011] In this specification, when two lines or planes are "parallel," it means that the angle (absolute value) they form is within the range of 0°±3°. When two lines or planes are "orthogonal" (and "perpendicular"), it means that the angle (absolute value) they form is within the range of 90°±3°.

[0012] In the following embodiment, an example in which the cooking device 1 of the present disclosure is applied to a toaster oven will be described.

[0013] (Embodiment 1) 1, 2, and 3 are schematic diagrams (perspective views) showing a cooking device 1 according to this embodiment. Of these, FIGS. 1 and 3 are diagrams showing a state in which the door 20 is closed (referred to as a closed state), and FIG. 2 is a diagram showing a state in which the door 20 is open (referred to as an open state). FIG. 3 is also a diagram in which a part of the door 20 is cut away from FIG. 1. FIG. 4 is a diagram showing a state in which the door 20 has been removed from the cooking device 1 shown in FIG. 1. FIG. 5 is a diagram (perspective view) showing a state in which the door 20 and the housing (outer wall) 11 have been removed from the cooking device 1, as viewed from approximately the X2 direction. FIG. 6 is a cross-sectional view taken along line A-A' in FIG. 1, as viewed from the X2 direction. FIG. 7 is a cross-sectional view taken along line A-A' in FIG. 4, as viewed from approximately the X1 direction (perspective view).

[0014] As shown in FIG. 1 and other figures, the cooking device 1 includes a main body 10 having a heating chamber 12 therein, and a door 20 provided on the main body 10.

[0015] (Main body 10) The main body 10 has a rectangular parallelepiped housing (outer wall) 11 with an opening 10a on the front, and has a heating chamber 12 inside the housing 11. The heating chamber 12 is surrounded by the inner wall of the main body 10, and has an open front portion. The inner walls of the main body 10 include a left wall 13, a right wall 14, a rear wall 15, a bottom wall 16, and a top wall 17. These inner walls are made of, for example, metal plates.

[0016] The main body 10 also preferably has a front bottom wall 19 below the opening 10a (see FIG. 4, etc.). The below of the opening 10a means the portion below the center of the opening 10a in the up-down direction. For example, the front bottom wall 19 may be positioned so that the front end (the end on the door 20 side) of the front bottom wall 19 overlaps the lower end of the opening 10a in a side view (see FIG. 11). The front bottom wall 19 is also made of, for example, a metal plate. Details of the front bottom wall 19 will be described later.

[0017] A food placement section 50 is provided inside the heating chamber 12, where food to be cooked is placed (see FIG. 2). The food placement section 50 is, for example, a grill or a cooking tray. Guide sections 51 are provided on the left side wall 13 and the right side wall 14 so as to extend horizontally in the front-to-rear direction, and the food placement section 50 can be moved between a state in which the food placement section 50 is stored within the heating chamber 12 and a state in which the front portion of the food placement section 50 has moved forward (in the Y1 direction) from within the heating chamber 12. The guide sections 51 move the food placement section 50 forward and backward in conjunction with the opening and closing of the door 20. When the door 20 is closed, the food placement section 50 is stored within the heating chamber 12, and when the door 20 is open, the front portion of the food placement section 50 has moved forward (in the Y1 direction) from within the heating chamber 12, as shown in FIG. 2.

[0018] Heaters 60 are provided in at least one of the upper and lower parts of heating chamber 12 (FIG. 4). For example, one or more upper heaters extending in the left-right direction are arranged in the upper part of heating chamber 12, and one or more lower heaters extending in the left-right direction are arranged in the lower part of heating chamber 12. When two or more upper heaters are arranged, they are arranged parallel to each other, for example, at positions in front and behind heating chamber 12, and when two or more lower heaters are arranged, they are also arranged parallel to each other, for example, at positions in front and behind heating chamber 12.

[0019] A frame 18 is provided around the opening 10a of the heating chamber 12 (see FIG. 4). The frame 18 is located between the housing 11 (outer wall) that forms the outer surface of the cooking appliance 1 and the inner walls of the main body 10, namely, the left side wall 13, the right side wall 14, the bottom wall 16, and the top wall 17.

[0020] The front surface of frame 18 can come into contact with door 20. Of the front surface of frame 18, the portions located to the left, right, and upper of opening 10a when cooking appliance 1 is viewed from the front are also referred to as left front frame 18a, right front frame 18b, and upper front frame 18c, respectively (see FIG. 4). Left front frame 18a, right front frame 18b, and upper front frame 18c can come into contact with door 20 when door 20 is in a closed state.

[0021] The left front frame portion 18a abuts (is in contact with) an edge portion 13A on the door 20 side of the left side wall 13 of the main body 10. The edge portion 13A of the left side wall 13 forms a step portion with the edge portion on the opening 10a side of the left front frame portion 18a. The right front frame portion 18b abuts an edge portion 14A on the door 20 side of the right side wall 14 of the main body 10. The edge portion 14A of the right side wall 14 forms a step portion with the edge portion (also referred to as edge portion 18B) on the opening 10a side of the right front frame portion 18b (see FIG. 8).

[0022] FIG. 8 is a diagram for explaining that a step portion S is formed between the edge of the side wall and the edge of the frame portion, and is a diagram (top view) of the vicinity of the right front frame portion 18b viewed from the Z1 direction. FIG. 8 also shows the packing P on the door 20 side. As shown in FIG. 8, the step portion S is formed between the edge portion 14A of the right side wall 14 and the edge portion 18B of the right front frame portion 18b. As a result, when the door 20 is in a closed state (i.e., when the right front frame portion 18b and the surface 22a on the door 20 side are closer to each other than in the state shown in FIG. 8), a recess C is formed by the packing P on the door 20 side, the edge portion 14A of the right side wall 14, and the edge portion 18B of the right front frame portion 18b. In this way, a step portion S is formed between the edge of the side wall of the main body portion 10 on the door 20 side and the edge of the frame portion 18 on the opening 10a side, so that when the door 20 is viewed in a planar view in the closed state, a recess C is formed by the gasket P on the door 20 side, the edge of the side wall, and the edge of the frame portion on the side wall.

[0023] (Door 20) Door 20 is provided on the front side of main body 10 and can openably and closably close opening 10a of heating chamber 12 (see FIG. 2). Specifically, door 20 is attached to the lower part of frame 18 of main body 10 so as to rotate up and down around its lower end side, and in the closed state, the surface of door 20 facing main body 10 comes into contact with the front surface of frame 18 (i.e., left front frame 18a, right front frame 18b, and upper front frame 18c), thereby closing opening 10a.

[0024] A viewing window 23 is provided in the center of the door 20, for example, to allow the user to look into the heating chamber 12, and a grip 25 is provided, for example, at the top of the door 20, to be gripped when opening or closing the door 20 (see FIG. 9). FIG. 9 is a perspective view of only the door 20 and the front bottom wall 19 of the cooking appliance 1 shown in FIG. 1, viewed from approximately the Y2 direction.

[0025] The door 20 has a door frame 21, which is the housing of the door 20, a door panel 22, and a sight window 23 (see FIG. 9). The sight window 23 is, for example, a transparent plate such as glass. The door frame 21 is, for example, a box-shaped housing that is thin in the front-to-rear direction and has an open rear surface 21b. The door frame 21 has an opening 23a at a position corresponding to the sight window 23, and is integrally formed with a boss or the like for attaching a handle 25. The door frame 21 is, for example, made of a resin molded product produced by pouring a resin material into an injection mold. The sight window 23 is attached to the front of the door frame 21 so as to cover the entire front surface.

[0026] Frame openings 21a for installing a rotation mechanism and a rotation shaft are provided on both the left and right sides of the lower part of the door 20 (see FIG. 9). As a result, when the door 20 is in an open state, the lower part of the door 20 does not come into contact with the lower part of the frame part 18, and the door 20 can be opened and closed smoothly.

[0027] A door panel 22 is attached to the rear surface 21b of the door frame 21. The door panel 22 is disposed on the heating chamber 12 side of the door frame 21 and is made of a metal material such as aluminum. When the door 20 is in the closed state, the door panel 22 can abut against the frame portion 18.

[0028] The door frame 21 may have a lower surface (lower wall), or the lower surface may be open. For example, in Fig. 15 described later, the door frame 21 has an open lower surface, and a front bottom wall portion 19 of the main body portion 10 is attached to the portion where the lower surface is located. For example, the front end portion (Y1 side end portion) of the front bottom wall portion 19 is connected to the rear surface 21b of the door frame 21, and the rear end portion (Y2 side end portion) is connected to the bottom wall 16 of the main body portion 10 (see Fig. 15 described later, etc.).

[0029] A packing P is disposed on the door 20. As shown in FIG. 9, the packing P is disposed on a surface 22a of the door panel 22 that can come into contact with the frame portion 18. The packing P is disposed so that, when the door 20 is viewed from above in the closed state (i.e., viewed from the Z1 direction), a recess C is formed by the edge of the side wall located on at least one of the left and right sides of the heating chamber 12 on the door 20 side, the frame portion 18, and the packing P (see FIGS. 3 and 10). FIG. 10 is an enlarged view of portion E1 in FIG. 3. As described above, a step portion S is formed on the main body portion 10 side, and therefore, when the door 20 is in the closed state, this step portion S and the packing P form the recess C (see also FIG. 8).

[0030] The packings P are preferably provided so as to be located on both the left and right sides of the opening 10a when the door 20 is in a closed state. For example, as shown in FIG. 9, the packings P are provided continuously or intermittently along the periphery of the viewing window 23 on the surface 22a of the door panel 22 that can abut against the frame portion 18. In the portions of the surface 22a that are located on the left and right sides of the opening 10a when the door 20 is in a closed state, the packings P are preferably provided continuously along the edges of the side walls and the edges of the frame that contact the edges of the side walls. As will be described later, a recess 27 for forming a steam exhaust port 80 may be provided in the upper part of the surface 22a, but the packings P do not have to be provided in the portion that serves as a path for steam to be discharged toward the recess 27 (see FIG. 9).

[0031] When the door 20 is closed, condensation may occur between the frame 18 and the door 20. When the packing P is arranged to form the recess C as described above, the condensation that occurs between the frame 18 and the door 20 can easily flow downward along the packing P, so the cooking appliance 1 of this embodiment can intentionally collect the condensation. In consideration of this point, it is preferable that the packing P is arranged so that the condensation flows downward along the packing P when the door 20 is closed.

[0032] As described above, the main body 10 preferably has a front bottom wall 19 below the opening 10a. The front bottom wall 19 has an inclined portion 19a that slopes downward toward the rear wall 15 of the main body 10, and is disposed so as to be located below the recess C (see FIGS. 5 and 9).

[0033] By positioning the front bottom wall portion 19 below the opening 10a, the front bottom wall portion 19 can receive condensation water that flows down along the surface of the door 20 facing the opening 10a and the inner surface of the door 20, and by positioning the front bottom wall portion 19 so that it is positioned below the recess C, the front bottom wall portion 19 can also receive condensation water that flows down along the packing P. Furthermore, by providing the front bottom wall portion 19 with the inclined portion 19a, this condensation water can easily flow down to the bottom wall 16. When the cooking appliance 1 is in use, the bottom wall 16 is at a high temperature, so the condensation water that flows down to the bottom wall 16 evaporates. Therefore, the condensation water is sufficiently prevented from flowing onto the installation surface of the cooking appliance 1.

[0034] The front bottom wall 19 may further have a horizontal portion 19b extending horizontally toward the rear wall 15 of the main body 10 (see FIG. 9). The front bottom wall 19 is disposed so as to be located below the recess C when the door 20 is closed, and the portion of the front bottom wall 19 that overlaps with the recess C in a plan view may be the horizontal portion 19b (see FIG. 5) or the inclined portion 19a.

[0035] (Drainage section 30) It is preferable that the cooking appliance 1 further includes a drainage section 30. The drainage section 30 is provided so as to be located at least below the recess C. The drainage section 30 includes a drainage hole 31 and a dew receiving section 32 that receives condensation water flowing down from above and directs it to the drainage hole 31 (see FIG. 11). By providing the cooking appliance 1 with the drainage section 30 in this way, it is possible to direct condensation water to an intended location, and to prevent the condensation water from flowing onto the installation surface, for example. FIG. 11 is an enlarged view of part E2 in FIG. 4.

[0036] The dew receiving portion 32 is inclined downward toward the drainage hole 31. That is, the lowest part of the inclined dew receiving portion 32 is open, and this opening serves as the drainage hole 31 (see FIG. 11). Condensed water passes through the drainage hole 31 and is drained downward.

[0037] As described above, the main body 10 preferably has a front bottom wall 19 below the opening 10a, and the front bottom wall 19 is preferably arranged so as to overlap at least a portion of the drainage section 30 in a plan view (see FIG. 11 ). In a side view, the front bottom wall 19 is preferably located above the drainage section 30. By arranging the front bottom wall 19 and the drainage section 30 so as to overlap in a plan view, the cooker 1 can more reliably collect condensation water that flows down from above when the door 20 is closed, using at least one of the front bottom wall 19 and the drainage section 30. In such a cooker 1, if the door 20 has a water guide section 90 as described below, condensation water generated inside the door 20 can also be sufficiently prevented from flowing out onto the installation surface of the cooker 1, thereby more effectively preventing the outflow of condensation water (see Embodiment 2 described below).

[0038] Drainage section 30 may be provided integrally so as to extend in the left-right direction from below left front frame section 18a to below right front frame section 18b, but from the viewpoint of preventing waste materials such as bread crumbs from entering drainage section 30, it is preferable that it be provided on both the left and right sides of opening 10a (see FIG. 4). That is, cooking appliance 1 preferably includes, as drainage section 30, a drainage section provided below left front frame section 18a and a drainage section provided below right front frame section 18b.

[0039] As will be described later, it is preferable that the cooking appliance 1 further includes an operating unit 40 arranged below the door 20, and it is preferable that the drainage unit 30 be provided on a top surface 41a of a housing 41 that constitutes this operating unit 40 (see FIGS. 11 to 13). As shown in FIGS. 11 to 13, a part of the top surface 41a of the housing 41 is opened to form a drainage hole 31, and the top surface 41a of the housing 41 is provided with a dew receiving portion 32 that is inclined downward toward the drainage hole 31. FIG. 12 is an enlarged view of part E3 in FIG. 5, and FIG. 13 is an enlarged view of part E4 in FIG. 6.

[0040] (Operation unit 40) Cooking appliance 1 preferably has an operation unit 40 arranged below door 20 (see FIG. 4, etc.). Operation unit 40 has a housing 41 that is open at the rear, and members that can be operated by the user (for example, a display screen 46, operation buttons 47, an operation dial 48, and a water tank 44) are provided on the front surface of housing 41. A drainage unit 30 including a drainage hole 31 and a dew receiving unit 32 is preferably provided on top surface 41a of housing 41 (see FIGS. 11 to 13).

[0041] For example, the operation unit 40 includes a housing 41 that is open at the rear, a control board 42 attached to the housing 41, and a board cover 43 that is disposed behind the control board 42 and covers the control board 42. In this embodiment, the housing 41 is integrally provided so as to extend in the left-right direction from the lower front side of the left front frame portion 18a to the lower front side of the right front frame portion 18b (see FIG. 4), and the control board 42 and the board cover 43 are provided below the front side of the right front frame portion 18b (see FIG. 12). For example, a display screen 46, operation buttons 47, an operation dial 48, etc. are electrically connected to the control board 42.

[0042] A drainage section 30 (first drainage section 30A) is provided on a top surface 41a of the housing 41, and the board cover 43 is arranged so that the drainage hole 31 and the top surface 43a of the board cover 43 overlap in a plan view, and the top surface 43a of the board cover 43 is inclined downward toward the rear wall 15 of the main body 10 (see FIG. 12). The drainage hole 31 located above the board cover 43 is also referred to as the first drainage hole 31A, the dew receiving section 32 inclined toward the first drainage hole 31 is also referred to as the first dew receiving section 32A, and the drainage section 30 including the first drainage hole 31 and the first dew receiving section 32 is also referred to as the first drainage section 30A.

[0043] In a side view (e.g., when viewed from the X2 side), the first drainage holes 31A provided on the top surface 41a of the housing 41 and the top surface 43a of the board cover 43 are arranged in this order from top to bottom (see FIG. 12). The top surface 43a of the board cover 43 is inclined downward toward the rear wall 15 of the main body 10. In FIG. 12, the inclined surface of the top surface 43a is denoted by the reference symbol 43b. Condensation water that flows from the first dew receiving portion 32A into the first drainage holes 31A flows through the first drainage holes 31A onto the top surface 43a of the board cover 43, then runs down the inclined surface 43b of the top surface 43a onto the bottom wall 16 of the main body 10 (see FIG. 12). When the cooking appliance 1 is in use, the bottom wall 16 is at a high temperature, so the condensation water that flows down onto the bottom wall 16 evaporates. This effectively prevents the condensation water from flowing onto the installation surface of the cooking appliance 1. The front part of the board cover 43 is arranged to cover the control board 42 so that the condensed water that has passed through the first drainage hole 31A does not come into contact with the control board 42.

[0044] The operating unit 40 may include a housing 41 that is open at the rear, a water tank 44 that is detachably disposed on the front side of the housing 41, and a water tank cover 45 that is disposed behind the water tank 44 to cover the water tank 44. In this embodiment, the housing 41 that constitutes the operating unit 40 is integrally provided so as to extend in the left-right direction from the lower front side of the left front frame portion 18a to the lower front side of the right front frame portion 18b (see FIG. 4, etc.), and the water tank 44 and the water tank cover 45 are provided on the lower front side of the left front frame portion 18a (see FIGS. 13 and 14). The user can pull the water tank 44 forward (in the Y1 direction) from the housing 41. FIG. 14 is an enlarged view of portion E5 in FIG. 7.

[0045] A drainage section 30 (second drainage section 30B) is provided on the top surface 41a of the housing 41. In this embodiment, the drainage sections 30 are provided in two locations on the top surface 41a of the housing 41: one on the front lower side of the left front frame section 18a and one on the front lower side of the right front frame section 18b (see FIG. 4). The water tank cover 45 is arranged so that the drainage hole 31 and the top surface 45a of the water tank cover 45 overlap in a plan view, and the top surface 45a of the water tank cover 45 is inclined downward toward the rear wall 15 of the main body 10 (see FIG. 13). The drainage hole 31 located above the water tank cover 45 is also referred to as the second drainage hole 31B, the dew receiving section 32 inclined toward the second drainage hole 31B is also referred to as the second dew receiving section 32B, and the drainage section 30 including the second drainage hole 31B and the second dew receiving section 32B is also referred to as the second drainage section 30B.

[0046] In a side view (e.g., when viewed from the X1 side), second drainage holes 31B provided on top surface 41a of housing 41 and top surface 45a of water tank cover 45 are arranged in this order from top to bottom (see FIG. 14). Top surface 45a of water tank cover 45 is inclined downward toward rear wall 15 of main body 10. Condensation water that flows from second dew receiving portion 32B into second drainage holes 31B flows through second drainage holes 31B onto top surface 45a of water tank cover 45, then runs down top surface 45a and onto bottom wall 16 of main body 10 (see FIG. 13). When cooking appliance 1 is in use, bottom wall 16 is at a high temperature, so the condensation water that flows onto bottom wall 16 evaporates. This effectively prevents condensation water from flowing onto the installation surface of cooking appliance 1.

[0047] As will be described later, when the cooking appliance 1 is provided with a waste receiving member 70 below the main body 10, the bottom wall 16 of the main body 10 preferably has a dew receiving portion 16a that receives condensation water flowing down from above, and drainage holes 16b that drain the condensation water into the waste receiving member 70 (see FIGS. 12 and 13). The dew receiving portion 16a is inclined downward toward the drainage holes 16b. The condensation water that flows from the dew receiving portion 16a into the drainage holes 16b flows down into the waste receiving member 70 located below, so that the condensation water is more sufficiently prevented from flowing out onto the installation surface of the cooking appliance 1.

[0048] The cooking appliance 1 of this embodiment preferably has a steam generation function that heats water to generate steam. Cookers with a steam generation function usually produce a particularly large amount of condensation water, but by arranging the packing P in a predetermined position as described above, the condensation water can be intentionally collected. Furthermore, by providing the cooking appliance 1 with the drainage section 30 as described above, the outflow of condensation water can be effectively prevented. The cooking appliance 1 with a steam generation function has, between the housing 11 that constitutes the main body 10 and the heating chamber 12, a pump (not shown) and a steam generator (not shown) that heats water supplied from the water tank 44 via the pump to generate steam, and an opening (not shown) is formed in the inner wall of the main body 10 through which steam is blown from the steam generator into the heating chamber 12.

[0049] Cooking appliance 1 may further include a steam outlet 80 for discharging steam inside heating chamber 12 to the outside (see FIG. 1). For example, by providing a recess 27 in the upper part of surface 22a that can come into contact with frame portion 18 of door panel 22 (see FIG. 9), an opening (steam outlet) 80 for discharging steam is formed between door 20 and upper front frame portion 18c when door 20 is in the closed state. Recess 27 may be provided in upper front frame portion 18c instead of on the door 20 side.

[0050] (Exhaust receiving member 70) The cooking appliance 1 preferably further includes a waste receiving member 70 detachably arranged below the main body 10 (FIG. 6). The waste receiving member 70 is a member that receives water such as condensed water and waste such as crumbs.

[0051] A holder 71 for holding the waste receiving member 70 is provided on the underside of the main body 10 (FIG. 6). The holder 71 can hold the waste receiving member 70 in a state where it is provided below the main body 10. Specifically, the holder 71 is formed of a plate-like member extending in the front-to-rear direction of the main body 10, and the space between the upper surface of the holder 71 and the bottom surface of the main body 10 is the placement area for the waste receiving member 70, i.e., the storage position for the waste receiving member 70. After cooking, for example, the user can remove the waste receiving member 70 from the cooking appliance 1 and wash it by pulling out the waste receiving member 70 in the front direction Y1.

[0052] (Embodiment 2) The door 20 of the cooking appliance 1 of this embodiment has a water guide portion 90 that guides condensed water on the inside of the door 20 downward on at least one of the left and right sides of the inner surface facing the main body 10 (see FIG. 14). This embodiment is otherwise the same as the first embodiment, so a duplicated description will be omitted.

[0053] Fig. 15 is a diagram (perspective view) that schematically illustrates the internal structure of the door 20 included in the cooking appliance 1 according to this embodiment. Fig. 15 corresponds to a diagram in which the door panel 22 has been removed from the door 20 shown in Fig. 9. In Fig. 15, water guide portions 90 (left water guide portion 90B and right water guide portion 90A) are provided on both the left and right sides of the inner surface of the door 20 that faces the main body portion 10, but water guide portions 90 may be provided on only one side. The number of water guide portions 90 provided on one side may be multiple.

[0054] The water guide portion 90 is formed so as to protrude from the rear surface 21b (the surface on the Y1 side) of the door frame 21 towards the main body portion 10. The height of the water guide portion 90 from the rear surface 21b is, for example, approximately 1 to 3 mm. The inclination angle (acute angle) of the water guide portion 90 in the left-right direction is, for example, approximately 5 to 45 degrees. The inclination angles of the left water guide portion 90B and the right water guide portion 90A may be the same or different. The water guide portion 90 is preferably made of resin. The water guide portion 90 may be formed integrally with the door frame 21, for example.

[0055] When the door 20 is viewed from the front in the closed state, the water guide section 90 is inclined so that the end of the water guide section 90 located on the side edge of the inner surface of the door 20 on which the water guide section 90 is provided is positioned upward. In Figure 15, the left water guide section 90B is inclined so that the left end is positioned upward and the right end is positioned downward, and the right water guide section 90A is inclined so that the right end is positioned upward and the left end is positioned downward. By arranging the water guide section 90 at an angle in this way, the water guide section 90 can receive condensation water that flows down the inner surface of the door 20 and guide the condensation water downward by the weight and surface tension of the condensation water.

[0056] When the door 20 is in the closed state, the water guide portion 90 is located above the rotation mechanism and rotation shaft (neither of which are shown) that rotate the door 20. This sufficiently prevents condensed water from flowing downward through the frame opening 21a formed for installing the rotation mechanism and the rotation shaft.

[0057] The water guide portion 90 is also preferably arranged so that the rear end of the lower end overlaps the front bottom wall portion 19 in a plan view (see FIG. 15). In this case, condensation water running down the water guide portion 90 when the door 20 is closed can flow down to the front bottom wall portion 19. This sufficiently prevents condensation water generated inside the door 20 from flowing out onto the installation surface of the cooking appliance 1.

[0058] In FIG. 15, the rear end a (Y1 end) of the lower end (right end) of the left water guide section 90B is located above the front bottom wall section 19, and the rear end b (Y1 end) of the lower end (left end) of the right water guide section 90A is also located above the front bottom wall section 19. More specifically, the rear end a of the right end of the left water guide section 90B and the rear end b of the left end of the right water guide section 90A are located above the inclined portion 19c of the front bottom wall section 19 (see FIG. 15). The inclined portion 19c may be located inside the door 20, i.e., in a portion that is not visible from the outside when the door panel 22 is attached (see FIG. 9). The inclined portion 19c is inclined downward toward the rear wall 15 of the main body section 10.

[0059] (Embodiment 3) In the first and second embodiments, the packing P is provided on the door 20, but the packing P may be provided on the frame 18 of the main body 10. In this case, a step portion is provided in the vertical direction (meaning the vertical direction in the closed state) on at least one portion of the surface 22a that can abut against the frame 18 of the door panel 22, on the left or right side of the viewing window 23 (see also FIG. 8). The packing P is arranged so that this step portion and the packing P provided on the frame 18 form a recess C when the door 20 is viewed from above in the closed state (i.e., when viewed from the Z1 direction).
