DETAILED DESCRIPTION

[0052] Reference Figure 1 to Figure 7 , a cooking device 10 with a detachable handle according to an embodiment of the present invention will be described.

[0053] like Figure 1 to Figure 3 As shown, the cooking device 10 with a detachable handle of the present embodiment includes a container-shaped cooking device 1 and a detachable handle 2 detachably attached to the cooking device 1. In the present embodiment, the cooking device 1 has a bottomed cylindrical shape with a central axis C as the center.

[0054] Here, the definition of directions used in this embodiment is described.

[0055] In the present embodiment, each configuration is described while appropriately setting an XYZ orthogonal coordinate system (three-dimensional orthogonal coordinate system) in each drawing.

[0056] In each figure, the Z-axis direction corresponds to the direction in which the central axis C of the cooking device 1 extends. In this embodiment, the Z-axis direction is called the up-down direction. The up-down direction (Z-axis direction) is the +Z side, and the down-down direction is the -Z side.

[0057] The direction perpendicular to the central axis C is called the radial direction. The direction close to the central axis C in the radial direction is called the radial inner side or simply the inner side, and the direction away from the central axis C is called the radial outer side or simply the outer side. In addition, the direction around the central axis C is called the circumferential direction.

[0058] In each figure, the X-axis direction and the Y-axis direction correspond to the direction in which the horizontal plane perpendicular to the up-down direction extends (horizontal direction). In this embodiment, the X-axis direction is referred to as the front-to-back direction, and the Y-axis direction is referred to as the left-to-right direction. The front side in the front-to-back direction (X-axis direction) is the +X side, and the rear side is the -X side. The left side in the left-to-right direction (Y-axis direction) is the +Y side, and the right side is the -Y side.

[0059] Each structure of the cooking device with a detachable handle 10 will be described in detail.

[0060] like Figure 1 As shown, the cooker 1 of this embodiment is in the shape of a container with an opening at the top, specifically, a frying pan, etc. The cooker 1 has a metal substrate composed of, for example, iron, stainless steel, aluminum, copper, titanium, or a composite material thereof. A coating composed of a fluorine material, etc., may also be provided on the surface of the substrate of the cooker 1. The cooker 1 is formed by performing a stamping process, a bending process, etc. on the substrate. In addition, the cooker 1 may also be renamed as a heating cooker, etc.

[0061] The cooking device 1 includes a bottom wall 11, a side wall 12, a folded portion 13, and an outer wall 14. In the present embodiment, the bottom wall 11, the side wall 12, the folded portion 13, and the outer wall 14 are integrally formed of a single member (base material).

[0062] The bottom wall 11 has a plate shape extending in a direction perpendicular to the central axis C, and in the present embodiment has a disk shape.

[0063] The side wall 12 is in a tubular shape with the central axis C as the center, and is roughly cylindrical in the present embodiment. The lower end of the side wall 12 is connected to the outer peripheral portion of the bottom wall 11. The side wall 12 extends upward from the outer peripheral portion of the bottom wall 11. Specifically, in the present embodiment, the side wall 12 extends upward as it extends from the outer peripheral portion of the bottom wall 11 toward the radial outside. That is, the diameter size of the side wall 12 gradually increases as it moves from the lower end connected to the bottom wall 11 toward the upper side. In addition, the diameter size of the side wall 12 may also be roughly constant from the lower end connected to the bottom wall 11 toward the upper side.

[0064] The folding portion 13 extends outward from the upper opening of the side wall 12. In the present embodiment, the folding portion 13 is provided in a circumferential portion (rear side) of the upper opening of the side wall 12. The folding portion 13 is in the shape of a plate extending in a direction (horizontal direction) perpendicular to the up and down directions, and a pair of plate surfaces thereof face the up and down directions. In the present embodiment, the folding portion 13 is in the shape of a curved band extending along the circumferential direction. Furthermore, in the present embodiment, the folding portion 13 extends in the horizontal direction, but may also be inclined obliquely upward or obliquely downward in the direction of the diameter expansion, for example. That is, the folding portion 13 may also be inclined relative to the horizontal plane (XY plane) as it extends in the up and down directions in the radial direction.

[0065] The outer wall portion 14 extends downward from the radially outer end portion of the folded portion 13, i.e., the outer end portion. In the present embodiment, the outer wall portion 14 is disposed in a circumferential portion (rear side) of the upper opening of the side wall 12 via the folded portion 13. The outer wall portion 14 is in the shape of a plate extending in a direction perpendicular to the radial direction, and a pair of plate surfaces thereof face the radial direction. The outer wall portion 14 is in the shape of a flat plate. In the present embodiment, the outer wall portion 14 is in the shape of a rectangular plate, and the circumferential dimension is greater than the vertical dimension.

[0066] In addition, the outer wall portion 14 may also be in the shape of a curved plate extending in the circumferential direction. That is, the outer wall portion 14 may also extend in the shape of an arc centered on the central axis C when viewed in a transverse section perpendicular to the central axis C. In this case, the plate surface of the outer wall portion 14 facing radially outward is in the shape of a convex curved surface bulging radially outward, and the plate surface of the outer wall portion 14 facing radially inward is in the shape of a concave curved surface recessed radially outward.

[0067] In the present embodiment, the circumferential dimension of the outer wall portion 14 is the same as the circumferential dimension of the folding portion 13. However, this is not limiting, and the circumferential dimension of the outer wall portion 14 may be larger than the circumferential dimension of the folding portion 13. Alternatively, the circumferential dimension of the outer wall portion 14 may be smaller than the circumferential dimension of the folding portion 13. In other words, the circumferential dimension of the folding portion 13 may be larger than the circumferential dimension of the outer wall portion 14.

[0068] like Figure 6 and Figure 7 As shown in FIG. 1 , the detachable handle 2 can be detachably fixed to the cooking device 1 for heating and cooking. The detachable handle 2 is composed of a resin component or a metal component with high heat resistance suitable for heating and cooking. Figure 2 As shown, the detachable handle 2 has a rod-like or rounded columnar shape that is easy for the user to hold with the palm of the hand, and extends in a substantially front-rear direction.

[0069] Specifically, in the example shown in the figure, the detachable handle 2 extends toward the upper side (+Z side) as it extends toward the rear side (-X side), and is slightly inclined relative to the front-rear direction (X-axis direction). However, this is not limited to this, and the detachable handle 2 may also extend parallel to the X-axis direction, for example.

[0070] In addition, if Figure 2 As shown, when the detachable handle 2 is viewed from the left and right direction (Y-axis direction), the upper surface of the detachable handle 2 is in the shape of a convex curved surface that bulges upward. In addition, in the side view, the lower surface of the detachable handle 2 is in the shape of a concave curved surface that is recessed upward. Therefore, when the user holds the detachable handle 2, the palm of the user is more likely to fit the detachable handle 2. However, the present invention is not limited to the above structure. For example, in the side view, at least one of the upper surface and the lower surface of the detachable handle 2 may also extend in a straight line.

[0071] The detachable handle 2 includes: a handle body 21; a mounting portion 22 provided on the handle body 21 and mounted on the cooking device 1; an operating portion 25 provided on the handle body 21 and connected to the mounting portion 22; a first force applying portion (force applying portion) 30; and a second force applying portion 31.

[0072] The handle body 21 extends in a substantially front-to-back direction. The overall shape of the handle body 21 is a rod or a rounded column. Specifically, the handle body 21 is in the shape of a polygonal column such as a rounded quadrilateral column, a cylindrical column, a semi-cylindrical column, or an elliptical column. The handle body 21 is in the shape of a hollowed-out column or a cylinder, and other components can be accommodated in its internal space.

[0073] The mounting portion 22 is disposed at the front end of the handle body 21. The mounting portion 22 can be detachably mounted on the cooking device 1 and fixed to the cooking device 1. Figure 6 As shown, the mounting portion 22 can be detachably mounted on the outer wall portion 14 of the cooking device 1. Figure 4 and Figure 5 As shown, the mounting portion 22 has a pair of wall portions 23 and 24 opened upward. The pair of wall portions 23 and 24 are arranged side by side in the front-rear direction.

[0074] One of the pair of wall portions 23 and 24, which is located on the front side, is provided to protrude to the front side from the front end surface of the handle body 21. One wall portion 23 is plate-shaped. Figure 2 to Figure 7 In each of the illustrated handles, one wall portion 23 is substantially L-shaped when viewed from the side.

[0075] like Figure 4 and Figure 5 As shown, one wall portion 23 can rotate around a rotation shaft 29 provided inside the handle body 21, and is supported by the handle body 21 via the rotation shaft 29. The rotation shaft 29 is cylindrical and extends in the left-right direction inside the handle body 21. In addition, one wall portion 23 may also be referred to as a first wall portion 23, etc.

[0076] One wall portion 23 includes a support wall portion 23 a protruding forward from the front end surface of the handle body 21 , a main body wall portion 23 b extending upward from the front end portion of the support wall portion 23 a , and an anti-slip protrusion 23 c .

[0077] The support wall 23a is in the shape of a plate extending in the front-rear direction, and its pair of plate surfaces face the up-down direction. The front side of the support wall 23a is located in front of the front end surface of the handle body 21, and the rear side of the support wall 23a is arranged inside the handle body 21.

[0078] The lower end of the main body wall portion 23b is connected to the front end of the supporting wall portion 23a. The main body wall portion 23b is in the shape of a plate extending in a direction perpendicular to the radial direction of the cooker 1, and a pair of plate surfaces thereof face the radial direction (front-rear direction). The main body wall portion 23b is in the shape of a flat plate. In the present embodiment, the main body wall portion 23b is in the shape of a polygonal plate such as a rectangular plate, or a semicircular plate protruding upward, and the dimension in the left-right direction (Y-axis direction) is larger than the dimension in the up-down direction (Z-axis direction). However, this is not limited to this, for example, the dimension in the up-down direction and the dimension in the left-right direction of the main body wall portion 23b may be substantially the same as each other, or the dimension in the left-right direction may be smaller than the dimension in the up-down direction.

[0079] Furthermore, as described above, when the outer wall portion 14 is in the shape of a curved plate extending in the circumferential direction around the central axis C, it is preferred that the main body wall portion 23b is formed in the shape of a curved plate extending in the circumferential direction in such a manner as to be in close contact with the plate surface (concave curved surface) of the outer wall portion 14 facing the radial inner side (see Figure 6 ). That is, in this case, the plate surface of the main body wall portion 23b facing the rear side (radially outward) is in the shape of a convex curved surface extending in the circumferential direction.

[0080] The anti-slip protrusion 23c is disposed on the rearward wall surface of one wall portion 23. Specifically, the anti-slip protrusion 23c protrudes rearward from the rearward plate surface (wall surface) of the main wall portion 23b. The anti-slip protrusion 23c contacts the radially inner plate surface of the outer wall portion 14.

[0081] In the present embodiment, the anti-slip protrusion 23c is rib-shaped and extends in the left-right direction. A plurality of anti-slip protrusions 23c are provided at intervals from each other. In the present embodiment, a plurality of rib-shaped anti-slip protrusions 23c are provided in a row in the up-down direction.

[0082] In addition, in the present embodiment, one wall portion 23 has a metal L-shaped plate-like body 23d and a rubber anti-skid cover 23e covering a portion of the L-shaped plate-like body 23d. The anti-skid cover 23e covers the front side portion of the L-shaped plate-like body 23d and the area of ​​the main wall portion 23b. In addition, an anti-skid protrusion 23c is provided on a portion of the anti-skid cover 23e. Specifically, the anti-skid protrusion 23c is provided on a portion of the wall surface of the main wall portion 23b that faces the rear side in the anti-skid cover 23e. Therefore, the rubber anti-skid protrusion 23c is in close contact with the outer wall portion 14 while elastically deforming, thereby obtaining an anti-skid function and suppressing accidental slippage of one wall portion 23 and the outer wall portion 14.

[0083] The other wall portion 24 located at the rear side of the pair of wall portions 23 and 24 is arranged on the front end surface of the handle body 21. The other wall portion 24 is a wall surface constituting at least a part of the front end surface of the handle body 21. In addition, the other wall portion 24 may also be referred to as a second wall portion 24 or the like.

[0084] The other wall portion 24 has a pressing wall surface 24 a facing the front side and a step portion 24 b facing the downward side.

[0085] The pressing wall 24a is disposed on the upper side of the front end surface of the handle body 21. The pressing wall 24a is in the shape of a plane extending in a direction perpendicular to the radial direction of the cooking device 1. Specifically, in the present embodiment, the pressing wall 24a is in the shape of a polygonal surface such as a rectangular surface, or in the shape of a semicircular surface protruding upward, and the size in the left-right direction (Y-axis direction) is larger than the size in the up-down direction (Z-axis direction). However, this is not limited to this, for example, the size of the pressing wall 24a in the up-down direction and the size in the left-right direction may be substantially the same as each other, or the size in the left-right direction may be smaller than the size in the up-down direction.

[0086] Furthermore, as described above, when the outer wall portion 14 is in the shape of a curved plate extending in the circumferential direction around the central axis C, it is preferred that the pressing wall surface 24a is formed into a curved concave surface extending in the circumferential direction so as to be in close contact with the plate surface (convex surface) of the outer wall portion 14 facing the radial outer side (see Figure 6 ).

[0087] The step portion 24b is arranged on the lower side of the pressing wall surface 24a. The step portion 24b is connected to the lower end of the pressing wall surface 24a and extends from the lower end to the rear side. The step portion 24b is a wall surface facing the lower side. The step portion 24b is arranged on the upper side of the supporting wall portion 23a separately from the supporting wall portion 23a.

[0088] In addition, although not particularly illustrated, the other wall portion 24 may further include a pressing protrusion that protrudes from the pressing wall surface 24a toward the front side. The pressing protrusion contacts the plate surface of the outer wall portion 14 that faces the radial outer side. The pressing protrusion may be provided with only one, or may be provided with a plurality of protrusions spaced apart from each other. In this case, the pressing protrusion can provide an anti-slip function, and the unexpected slippage of the other wall portion 24 and the outer wall portion 14 can be suppressed.

[0089] The pair of wall portions 23 and 24 can be moved closer to or farther from each other by operating the operation portion 25 described later. The outer wall portion 14 is inserted between the pair of wall portions 23 and 24 opened upward from the upper side, the left-right direction, or the circumferential direction around the central axis C. In other words, the mounting portion 22 is mounted on the outer wall portion 14 from the lower side, the left-right direction, or the circumferential direction around the central axis C.

[0090] like Figure 2 to Figure 7 As shown, the operating portion 25 switches the mounting portion 22 to a closed state in which the outer wall portion 14 is clamped between the pair of wall portions 23 and 24 (see Figure 2 , Figure 4 and Figure 6 ), and the open state where the outer wall portion 14 can be pulled out from between the pair of wall portions 23 and 24 (see Figure 3 , Figure 5 and Figure 7 ).

[0091] In detail, Figure 4 and Figure 5 As shown, the operating portion 25 includes: a rod 26 fixed to one wall 23 of a pair of wall portions 23 and 24 of the mounting portion 22; a locking mechanism 27 that locks the rod 26 when the mounting portion 22 is in a closed state; and a lock release mechanism 28 that releases the locking state of the rod 26 by the locking mechanism 27.

[0092] The rod 26 is fixed to the supporting wall portion 23a of the one wall portion 23. In addition, the rod 26 can rotate around the rotation axis 29 provided inside the handle body 21 and is supported by the handle body 21. That is, the rod 26 and the one wall portion 23 rotate integrally around the rotation axis 29. Figure 5 When the mounting portion 22 is in the open state, if the user holds the detachable handle 2 with the palm of his hand and pushes the portion of the rod 26 exposed outside the handle (the rod body 26a described later) downward, the rod 26 and one wall portion 23 rotate around the rotation axis 29, so that the mounting portion 22 becomes Figure 4 Shown in closed state.

[0093] The rod 26 includes: a rod main body portion 26a, which is arranged at the upper part of the handle body 21 and exposed to the outside of the handle; a rod connecting portion 26b, which is arranged inside the handle body 21 and connects the rear side portion of the supporting wall portion 23a with the rod main body portion 26a; and an extension portion 26c, which extends from the rod main body portion 26a to the inside of the handle body 21.

[0094] The rod body 26a extends in the front-rear direction. The rod connection part 26b is made of metal, for example, and is formed integrally with the L-shaped plate-shaped body 23d of one wall part 23. The rear end of the rod connection part 26b is fixed to the rod body 26a. The extension part 26c is provided to hang downward from the rod body 26a.

[0095] The lock mechanism 27 is provided inside the handle body 21. The lock mechanism 27 has a locked portion 27a provided at a part of the rod 26, and a locking portion 27b detachably locked to the locked portion 27a.

[0096] In this embodiment, the locked portion 27a is provided at the lower end of the extended portion 26c and is formed in a hole shape facing the front side. The locking portion 27b is provided inside the handle body 21 and is formed in a shaft shape or a pin shape extending in the front-rear direction. The locking portion 27b is inserted into the guide hole 21a provided inside the handle body 21. The locking portion 27b is guided by the guide hole 21a to move in the front-rear direction.

[0097] The user pushes the rod 26 (rod body 26a) downward. Figure 4As shown in FIG. 1 , when the mounting portion 22 is in the closed state, the rear end of the locking portion 27b is inserted into the recessed locked portion 27a, so that the locked portion 27a and the locking portion 27b are locked, thereby locking the rod 26. In addition, at this time, the locking mechanism 27 locks the wall portion 23 fixed to the rod 26 together with the rod 26. That is, the locking mechanism 27 locks the mounting portion 22 in the closed state.

[0098] The lock release mechanism 28 includes a release body portion 28 a disposed at the lower portion of the handle body 21 , and a connection portion 28 b disposed inside the handle body 21 and rotatably connecting the release body portion 28 a and the locking portion 27 b .

[0099] A part of the release main body 28a is arranged inside the handle body 21, and another part (hereinafter sometimes referred to as a release button) is exposed outside the handle. Specifically, the release button is arranged at a position close to the front end of the lower surface of the handle body 21. It is preferred that the release button is located at a position closer to the front side than the part where the user holds the detachable handle 2. The release main body 28a can swing around a swing shaft 32 provided inside the handle body 21 and is supported by the handle body 21. The swing shaft 32 is cylindrical and extends in the left-right direction inside the handle body 21.

[0100] The connection part 28b is provided in the part of the release main body part 28a which is located on the upper rear side of the swing shaft 32. The connection part 28b is connected to the front end part of the locking part 27b.

[0101] exist Figure 4 In the closed state of the mounting portion 22 shown in the figure, if the user keeps holding the detachable handle 2 and operates the release button of the lock release mechanism 28 with the index finger or the like (such as Figure 3 Press backward as shown), then Figure 5 As shown in FIG. 1 , the release body 28a swings around the swing shaft 32, so that the locking portion 27b of the lock mechanism 27 connected to the connecting portion 28b is pulled forward. As a result, the locking state between the locking portion 27b and the locked portion 27a is released, and the locking state of the rod 26 by the locking mechanism 27 is released. When the lock of the rod 26 is released, the lock of the closed state of the mounting portion 22 is also released, so that the mounting portion 22 can be opened.

[0102] The first force applying portion (force applying portion) 30 is provided on the handle body 21 and applies force to the mounting portion 22 from Figure 4 The closed state shown is Figure 5The first force applying part 30 is, for example, a tension coil spring, and is disposed inside the handle body 21. One end of the first force applying part 30 is connected to the handle body 21, and the other end of the first force applying part 30 is connected to the rod 26 or one wall portion 23. In the example shown in the figure, one end of the first force applying part 30 is connected to the front wall portion of the handle body 21 (the back side of the other wall portion 24), and the other end of the first force applying part 30 is connected to the rod connecting portion 26b.

[0103] The first force applying portion 30 applies force to the one wall portion 23 in a direction (front side) in which the one wall portion 23 is away from the other wall portion 24. In other words, the first force applying portion 30 also applies force to the rod 26 from Figure 4 The closed state of the rod 26 is shown Figure 5 Specifically, the first biasing portion 30 biases one wall portion 23 and the rod 26 so as to rotate them about the rotation axis 29 from the closed state to the open state.

[0104] Therefore, if the locking state of the rod 26 and the mounting portion 22 by the locking mechanism 27 is released by the lock release mechanism 28, the one wall portion 23 and the other wall portion 24 are separated by the force of the first force applying portion 30, and the mounting portion 22 is stably opened. In addition, along with this, the rod 26 is also stably opened.

[0105] Furthermore, in this embodiment, the mounting portion 22 is Figure 6 The closed state shown becomes Figure 7 In the open state shown, the cooking device 1 is tilted by its own weight, so that the outer wall portion 14 is caught between the pair of wall portions 23, 24. Figure 7 In the example shown, the outer wall portion 14 is hooked between one wall portion 23 and the other wall portion 24, thereby being locked between the pair of wall portions 23 and 24. Specifically, the connection portion between the folded portion 13 and the outer wall portion 14 abuts against the upper end rear side of one wall portion 23, and the lower end side of the outer wall portion 14 abuts against the lower end side (front end side of the step portion 24b) of the other wall portion 24, thereby locking the cooking device 1 between the pair of wall portions 23 and 24. In this way, the cooking device 1 can be prevented from falling off from the detachable handle 2.

[0106] In addition, the second force applying portion 31 is provided on the handle body 21, and applies force to the release body portion 28a of the lock release mechanism 28 from Figure 5 The unlocked position shown is Figure 4 The second force applying portion 31 has a function of maintaining the lock release mechanism 28 in the locked position. The second force applying portion 31 is, for example, a tension coil spring, etc., and is arranged inside the handle body 21. The second force applying portion 31 is inserted into a through hole or a not-shown cutout that penetrates the rod connecting portion 26b in the front-rear direction.

[0107] In the example shown in the figure, one end of the second urging portion 31 is connected to the rotation shaft 29. In addition, the other end of the second urging portion 31 is connected to a portion of the release body 28a located below and in front of the swing shaft 32. The second urging portion 31 urges the release body 28a so that it swings from the lock release position to the lock position around the swing shaft 32.

[0108] like Figure 5 As shown in FIG. 1 , when the user releases the release button of the lock release mechanism 28 while pushing the release button to the rear side, the release main body 28a swings around the swing axis 32 by the force of the second force applying part 31. Specifically, the release main body 28a swings from the lock release position to the lock position by the force of the second force applying part 31, but at this time, the mounting part 22 and the rod 26 are maintained in the open state by the force of the first force applying part 30.

[0109] In the cooking device 10 with a detachable handle of the present embodiment described above, the cooking device 1 such as a frying pan is provided with a folded portion 13 protruding outward from the upper opening of the side wall 12, and an outer wall portion 14 protruding downward from the folded portion 13. In addition, the mounting portion 22 of the detachable handle 2 has a pair of wall portions 23 and 24 opening upward, and the outer wall portion 14 is inserted between the pair of wall portions 23 and 24.

[0110] When the outer wall 14 is inserted between the pair of wall portions 23 and 24, the user operates the operating portion 25 (lever 26) to close the mounting portion 22, thereby clamping the outer wall 14 between the pair of wall portions 23 and 24, and fixing the detachable handle 2 to the cooking device 1. In addition, the user operates the operating portion 25 (lock release mechanism 28) to open the mounting portion 22, thereby pulling out the outer wall 14 from between the pair of wall portions 23 and 24, and releasing the fixing state of the detachable handle 2 and the cooking device 1.

[0111] In this embodiment, the mounting portion 22 of the detachable handle 2 is not arranged on the inner side of the side wall 12 of the cooking device 1, and one wall portion 23 (the front wall portion 23) of the pair of wall portions 23 and 24 of the mounting portion 22 is arranged between the side wall 12 and the outer wall portion 14 of the cooking device 1, and is thus covered from the upper side by the folded portion 13. Therefore, it is possible to prevent the detachable handle 2 from being contaminated by the cooking material, and it is hygienic. In addition, the detachable handle 2 is not easily contaminated, so the handle cleaning operation after use can be omitted or simplified, and the cleaning performance is good.

[0112] Furthermore, when the circumferential dimension of the folded portion 13 is larger than the circumferential dimension of the outer wall portion 14 , adhesion of the cooked food to the one wall portion 23 can be further suppressed, and the above-mentioned effects become more significant.

[0113] In addition, the outer wall portion 14 of the cooking device 1 is inserted between the pair of wall portions 23 and 24 that are open to the upper side, so even if the user erroneously operates the operation portion 25 (lock release mechanism 28) and accidentally switches the mounting portion 22 from the closed state to the open state, the cooking device 1 is tilted by its own weight, and the outer wall portion 14 is easily hooked on the wall portions 23 and 24. Therefore, in this embodiment, it is possible to prevent the cooking device 1 from falling due to erroneous operation by the user, and safety is high.

[0114] In the present embodiment, when the attachment portion 22 is in the open state, the cooking device 1 is tilted by its own weight, and thereby the outer wall portion 14 is locked between the pair of wall portions 23 and 24 .

[0115] In this case, even if the user erroneously operates the operation portion 25 and accidentally switches the mounting portion 22 from the closed state to the open state, the cooking device 1 is tilted by its own weight, and the outer wall portion 14 is locked by being hooked between the pair of wall portions 23 and 24. Therefore, the cooking device 1 is more stably prevented from falling due to erroneous operation by the user.

[0116] In the present embodiment, the folded portion 13 and the outer wall portion 14 of the cooking device 1 are provided in a portion of the upper opening of the side wall 12 in the circumferential direction.

[0117] In this case, by providing the folded portion 13 and the outer wall portion 14 which are part of the circumference of the upper opening of the side wall 12, the detachable handle 2 can be hygienically and safely attached to and detached from the cooker 1, while suppressing an increase in the overall weight of the cooker 1 and an increase in volume when stored.

[0118] In addition, in the present embodiment, the side wall 12, the folded portion 13, and the outer wall portion 14 of the cooking device 1 are integrally formed by a single member.

[0119] For example, when a bracket for mounting a handle is fixed to the side wall of a cooking device by welding and a detachable handle is mounted on the bracket as in the prior art, welding marks are formed on the inner surface (inner surface) of the side wall, which deteriorates the appearance of the cooking device, or dirt from the cooking food accumulates on the unevenness of the welding marks. In addition, even when the bracket is fixed to the side wall of the cooking device by screws or rivets, the appearance of the cooking device is deteriorated, or dirt easily accumulates on the unevenness of the screws or rivets (for example, refer to Japanese Patent Gazette No. 3232034, etc.).

[0120] In contrast, in the above-mentioned structure of the present embodiment, the side wall 12, the folded portion 13 and the outer wall portion 14 of the cooking device 1 are integrally formed by a single component, so when the folded portion 13 and the outer wall portion 14 are provided on the side wall 12, the appearance of the cooking device 1 is not damaged by welding marks, screws, rivets, etc. Thus, the appearance design of the cooking device 1 is excellent in aesthetics. In addition, no unevenness is generated on the side wall 12 of the cooking device 1, so that the cooked food does not accumulate and is contaminated, and it is hygienic. In addition, since the steps of welding and riveting are not required, the manufacturing of the cooking device 1 becomes easy, and the manufacturing cost can be reduced.

[0121] However, the present invention is not necessarily limited to molding the folded portion 13 and the outer wall portion 14 of the cooking device 1 without welding as described above. For example, a component having the shape of the folded portion 13 and the outer wall portion 14 may be molded as a whole by molding and welding the upper end portion of the side wall 12 of the cooking device 1 to the inner circumference of the folded portion 13. In the former method, for example, the folded portion 13 and the outer wall portion 14 of the cooking device 1 can be molded as a whole by casting, and in the latter method, the folded portion 13 and the outer wall portion 14 of the cooking device 1 can be molded as a whole by stamping and welding. That is, the most suitable method can be selected by studying the manufacturing cost, the manufacturing process, the appearance of the finished product, etc.

[0122] In addition, in the present embodiment, the operating portion 25 includes: a rod 26 fixed to one wall 23 of a pair of wall portions 23 and 24 of the mounting portion 22; a locking mechanism 27 that locks the rod 26 when the mounting portion 22 is in a closed state; and a lock release mechanism 28 that releases the locking state of the rod 26 by the locking mechanism 27.

[0123] In this case, the user operates the lever 26 to allow one wall 23 (front wall 23) to approach the other wall 24 (rear wall 24), thereby sandwiching the outer wall 14 between the pair of walls 23, 24. Thus, the cooking device 1 can be held by the detachable handle 2.

[0124] In addition, in this state (the closed state of the mounting portion 22), the rod 26 is locked by the locking mechanism 27, thereby stably maintaining the closed state of the mounting portion 22. Therefore, it is possible to suppress the undesirable situation that the detachable handle 2 accidentally falls off from the cooking device 1. In addition, in the present embodiment, the user usually holds the detachable handle 2 (handle body 21) with the palm of the hand, thereby maintaining the rod 26 in the closed state, and thus the lock of the rod 26 is not released. Therefore, even in the case of a user's mistaken use, the detachable handle 2 is prevented from accidentally falling off from the cooking device 1, and the cooking device 1 is prevented from falling off from the detachable handle 2, and it functions as a double safety mechanism.

[0125] Furthermore, by the user operating the lock release mechanism 28 to release the locked state of the rod 26, the one wall portion 23 can be separated from the other wall portion 24, and the outer wall portion 14 can be pulled out from between the pair of wall portions 23 and 24. Thus, the detachable handle 2 can be removed from the cooking device 1.

[0126] In addition, in the present embodiment, the detachable handle 2 includes a first force applying portion 30 , which is provided on the handle body 21 and applies force to the mounting portion 22 from the closed state to the open state.

[0127] In this case, when the locking state of the rod 26 is released by the lock release mechanism 28, the mounting portion 22 is returned from the closed state to the open state by the first force applying portion 30. Thus, the outer wall portion 14 can be easily pulled out from between the pair of wall portions 23 and 24, and when the detachable handle 2 is mounted on the cooking device 1 next time, the outer wall portion 14 can be easily inserted between the opened pair of wall portions 23 and 24. Therefore, the cooking device 10 with a detachable handle is easy to use.

[0128] Furthermore, in the present embodiment, the second biasing portion 31 maintains the lock release mechanism 28 at the locked position by its biasing force.

[0129] In this case, the second biasing portion 31 suppresses the lock release mechanism 28 from accidentally switching from the locked position to the unlocked position. Therefore, it is also possible to suppress the mounting portion 22 from accidentally switching from the closed state to the open state.

[0130] In addition, the present invention is not limited to the above-mentioned embodiments, and for example, as described below, structural changes can be made within the scope of the main purpose of the present invention. In addition, in the illustration of the modified example, the same figure mark is marked for the same structure as the above-mentioned embodiment, and the main difference is described below.

[0131] Figure 8 This is a side cross-sectional view of a portion of a cooking device 20 with a detachable handle showing a first modification of the above-described embodiment, showing an open state of the mounting portion 22. In the first modification, the outer wall portion 14 has a flange portion 14a protruding outward from the lower end portion of the outer wall portion 14.

[0132] In this case, even if the user erroneously operates the operation portion 25 (lock release mechanism 28) and accidentally switches the mounting portion 22 from the closed state to the open state, the cooking device 1 is tilted by its own weight, so that the flange portion 14a of the outer wall portion 14 is more likely to contact the other wall portion 24 (the rear wall portion 24) of the pair of wall portions 23 and 24. Therefore, the cooking device 1 is further prevented from falling due to erroneous operation by the user.

[0133] Furthermore, in the first modification, the step portion 24 b of the other wall portion 24 faces the flange portion 14 a from above.

[0134] In this case, when the mounting portion 22 is changed from the closed state to the open state due to a user's erroneous operation, the flange portion 14a of the outer wall portion 14 contacts and hooks the step portion 24b of the other wall portion 24 (the rear wall portion 24) from the bottom. Therefore, it is possible to more stably suppress the undesirable situation that the cooking device 1 falls due to a user's erroneous operation or the like.

[0135] Fig. 9 1 is a side cross-sectional view of a portion of a cooking device 40 with a detachable handle according to a second modified example of the above-mentioned embodiment, showing an open state of the mounting portion 22. Fig.10 It is a side cross-sectional view of a portion of a cooking device 50 with a detachable handle according to a third modified example of the above-mentioned embodiment, and shows an open state of the mounting portion 22 .

[0136] As a second variant, the cooking device 40 with a detachable handle has a shorter length (radial dimension) of the folded portion 13 and a narrower distance (radial dimension) between the outer wall portion 14 and the side wall 12 than in the above-mentioned embodiment. As a third variant, the cooking device 50 with a detachable handle has a wider interval between one wall portion 23 and the other wall portion 24 than in the above-mentioned embodiment. In the above-mentioned second and third variants, when the mounting portion 22 is in the open state, the cooking device 1 tilts due to its own weight, whereby one wall portion 23 of the pair of wall portions 23, 24 is stuck between the outer wall portion 14 and the side wall 12. In addition, in Fig. 9 and Fig.10 In the embodiment, the outer wall portion 14 does not contact the other wall portion 24 of the mounting portion 22 .

[0137] In this case, even if the user erroneously operates the operation portion 25 (lock release mechanism 28) and accidentally switches the mounting portion 22 from the closed state to the open state, the cooking device 1 is tilted by its own weight, and one wall portion 23 (the front wall portion 23) of the pair of wall portions 23 and 24 is hooked between the outer wall portion 14 and the side wall 12, thereby being locked. Therefore, it is possible to stably prevent the cooking device 1 from falling due to erroneous operation by the user.

[0138] Fig.11 This is a perspective view of a cooking device 1 of a cooking device 60 with a detachable handle, which is a fourth variation of the above-mentioned embodiment. In this fourth variation, the cooking device 1 is, for example, a pot or the like. That is, the vertical dimension (depth dimension) of the cooking device 1 may be shallow or deep. In addition, in this fourth variation, the folded portion 13 and the outer wall portion 14 are provided over the entire circumference of the upper opening of the side wall 12.

[0139] In this case, when the detachable handle 2 is mounted on the cooking device 1, it can be mounted from any position in the circumferential direction, so the degree of freedom is high and the usability is improved.

[0140] In the above-mentioned embodiment and each modified example, the structure in which the other wall portion 24 on the rear side of the pair of wall portions 23 and 24 is fixed and the one wall portion 23 on the front side moves, thereby the outer wall portion 14 is stuck between the pair of wall portions 23 and 24. The present invention is not limited to this, and the one wall portion 23 on the front side of the pair of wall portions 23 and 24 may be fixed, and the other wall portion 24 on the rear side may slide forward and backward, or rotate, thereby the outer wall portion 14 is stuck between the pair of wall portions 23 and 24, and the cooking device 1 can be attached to and detached from the detachable handle 2. Specifically, it may be configured that one wall portion 23 is fixed to the handle body 21, and the other wall portion 24 moves relative to the handle body 21 and the one wall portion 23, thereby the one wall portion 23 and the other wall portion 24 can approach or move away from each other.

[0141] In this case, the support wall 23a and the main body wall 23b on the one wall 23 side may be made of metal, and a rubber anti-slip cover may be provided on the other wall 24 side. That is, the anti-slip cover may be provided on the other wall 24 instead of on the one wall 23. According to this, the metal support wall 23a exists below the other wall 24, and the rubber anti-slip cover having lower heat resistance than metal is not exposed below, so that the rubber anti-slip cover (the other wall 24) can be kept away from the fire during cooking, and safety is further improved.

[0142] Although not particularly shown in the drawings, the cooking device 1 is not limited to a bottomed cylindrical shape centered on the central axis C, and may be, for example, a bottomed quadrilateral cylindrical shape or a bottomed polygonal cylindrical shape.

[0143] The present invention can also combine the various structures described in the above-mentioned embodiments and modifications, etc., within the scope of not departing from the main purpose of the present invention, and can also add, omit, replace, and make other changes to the structure. In addition, the present invention is not limited by the above-mentioned embodiments, etc., but only by the claims.
