DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0021] A cooking appliance 10 with a detachable handle according to one embodiment of the present invention will be described with reference to Figs. 1 to 7. As shown in Figures 1 to 3, a cooking device 10 with a detachable handle of this embodiment includes a container-shaped cooking device 1 and a detachable handle 2 that is detachably attached to the cooking device 1. In this embodiment, the cooking device 1 has a cylindrical shape with a bottom and is centered on a central axis C.
[0022] Here, the definitions of directions used in this embodiment will be described. In this embodiment, an XYZ orthogonal coordinate system (three-dimensional orthogonal coordinate system) is appropriately set in each drawing, and each configuration will be described. In each drawing, the Z-axis direction corresponds to the direction in which the central axis C of the cooking appliance 1 extends. In this embodiment, the Z-axis direction is called the up-down direction. In the up-down direction (Z-axis direction), the upper side is the +Z side, and the lower side is the -Z side.
[0023] The direction perpendicular to the central axis C is called the radial direction. Of the radial directions, the direction approaching the central axis C is called the radially inner direction or simply the inner direction, and the direction away from the central axis C is called the radially outer direction or simply the outer direction. Additionally, the direction going around the central axis C is called the circumferential direction.
[0024] In each figure, the X-axis direction and the Y-axis direction correspond to the direction in which a horizontal plane perpendicular to the up-down direction extends (horizontal direction). In this embodiment, the X-axis direction is called the front-to-back direction, and the Y-axis direction is called the left-to-right direction. In the front-to-back direction (X-axis direction), the front side is the +X side, and the rear side is the -X side. In the left-to-right direction (Y-axis direction), the left side is the +Y side, and the right side is the -Y side.
[0025] Each component of the cooking appliance with detachable handle 10 will now be described in detail. As shown in FIG. 1, the cooking device 1 of this embodiment is in the form of a container with an open top, specifically, for example, a frying pan. The cooking device 1 has a metal base material made of, for example, iron, stainless steel, aluminum, copper, titanium, or a composite material thereof. The surface of the base material of the cooking device 1 may be provided with a coating made of a fluorine material or the like. The cooking device 1 is formed by subjecting the base material to a pressing process, a bending process, or the like. The cooking device 1 may also be referred to as a heating cooking device or the like.
[0026] The cooking appliance 1 has a bottom wall 11, a side wall 12, a folded portion 13, and an outer wall portion 14. In this embodiment, the bottom wall 11, the side wall 12, the folded portion 13, and the outer wall portion 14 are integrally formed from a single member (base material).
[0027] The bottom wall 11 has a plate shape extending in a direction perpendicular to the central axis C, and in this embodiment, has a disk shape.
[0028] The side wall 12 is tubular about the central axis C, and is substantially cylindrical in this embodiment. The lower end of the side wall 12 is connected to the outer periphery of the bottom wall 11. The side wall 12 extends upward from the outer periphery of the bottom wall 11. Specifically, in this embodiment, the side wall 12 extends upward from the outer periphery of the bottom wall 11 toward the radially outward side. That is, the diameter of the side wall 12 is gradually increased from the lower end connected to the bottom wall 11 toward the upper side. The diameter of the side wall 12 may be substantially constant from the lower end connected to the bottom wall 11 toward the upper side.
[0029] The folded portion 13 extends outward from the upper opening of the side wall 12. In this embodiment, the folded portion 13 is provided in a part (rear side) of the upper opening of the side wall 12 in the circumferential direction. The folded portion 13 is in the form of a plate extending in a direction perpendicular to the up-down direction (horizontal direction), and a pair of plate surfaces face the up-down direction. In this embodiment, the folded portion 13 is in the form of a curved strip extending along the circumferential direction. Note that in this embodiment, the folded portion 13 extends in the horizontal direction, but may be inclined, for example, obliquely upward or downward in the radial expansion direction. That is, the folded portion 13 may extend in the up-down direction as it approaches the radial direction, and may be inclined with respect to the horizontal plane (XY plane).
[0030] The outer wall portion 14 extends downward from the radially outer end, i.e., the outer end, of the folded portion 13. In this embodiment, the outer wall portion 14 is provided on 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 form of a plate extending in a direction perpendicular to the radial direction, and a pair of plate surfaces face in the radial direction. The outer wall portion 14 is in the form of a flat plate. In this embodiment, the outer wall portion 14 is in the form of a rectangular plate, and the circumferential dimension is larger than the vertical dimension.
[0031] The outer wall portion 14 may have a curved plate shape extending along the circumferential direction. That is, the outer wall portion 14 may extend in an arc shape centered on the central axis C in a cross-sectional view perpendicular to the central axis C. In this case, the plate surface of the outer wall portion 14 facing radially outward is a convex curved surface bulging radially outward, and the plate surface of the outer wall portion 14 facing radially inward is a concave curved surface recessed radially outward.
[0032] In this embodiment, the dimension of the outer wall portion 14 along the circumferential direction and the dimension of the folded-back portion 13 along the circumferential direction are the same. However, this is not limited thereto, and the dimension of the outer wall portion 14 along the circumferential direction may be larger than the dimension of the folded-back portion 13 along the circumferential direction. Alternatively, the dimension of the outer wall portion 14 along the circumferential direction may be smaller than the dimension of the folded-back portion 13 along the circumferential direction. In other words, the dimension of the folded-back portion 13 in the circumferential direction may be larger than the dimension of the outer wall portion 14 in the circumferential direction.
[0033] As shown in Figures 6 and 7, the detachable handle 2 is detachably fixed to a cooking appliance 1 for cooking. The detachable handle 2 is made of a highly heat-resistant resin or metal member suitable for cooking. As shown in Figure 2, the detachable handle 2 has a rod-like or rounded columnar outer shape that is easy for a user to grip with the palm of their hand, and extends substantially in the front-rear direction.
[0034] Specifically, in the illustrated example, the detachable handle 2 extends upward (+Z side) toward the rear (-X side) and is slightly inclined with respect to the front-rear direction (X-axis direction). However, the present invention is not limited to this, and the detachable handle 2 may extend, for example, parallel to the X-axis direction.
[0035] 2, in a side view of the detachable handle 2 seen from the left-right direction (Y-axis direction), the upper surface of the detachable handle 2 is a curved convex surface that bulges upward. In addition, in this side view, the lower surface of the detachable handle 2 is a curved concave surface that recesses upward. This makes it easier for the user's palm to fit the detachable handle 2 when the user grips the detachable handle 2. However, the configuration is not limited to the above, and for example, in this side view, at least one of the upper surface and the lower surface of the detachable handle 2 may extend linearly.
[0036] The detachable handle 2 has a handle main body 21, an attachment portion 22 provided on the handle main body 21 and attached to the cooking appliance 1, an operating portion 25 provided on the handle main body 21 and connected to the attachment portion 22, a first urging portion (urging portion) 30, and a second urging portion 31.
[0037] The handle body 21 extends substantially in the front-rear direction. The handle body 21 has an overall outer shape that is rod-like or rounded columnar. Specifically, the outer shape of the handle body 21 is, for example, a polygonal column such as a rectangular column with rounded corners, a cylinder, a semi-cylinder, or an elliptical column. The handle body 21 is columnar or tubular with a hollowed-out interior, and other components can be accommodated in the internal space.
[0038] The attachment part 22 is disposed at the front end of the handle body 21. The attachment part 22 is detachably attached to the cooker 1 and fixed to the cooker 1. Specifically, as shown in Fig. 6, the attachment part 22 is detachably attached to the outer wall part 14 of the cooker 1. As shown in Figs. 4 and 5, the attachment part 22 has a pair of walls 23, 24 that open upward. The pair of walls 23, 24 are disposed side by side in the front-to-rear direction.
[0039] Of the pair of walls 23, 24, the wall 23 located on the front side is provided to protrude forward from the front end surface of the handle body 21. The wall 23 is plate-shaped. The wall 23 is substantially L-shaped in the side view of each handle shown in Figs. 2 to 7.
[0040] 4 and 5, one wall portion 23 is rotatable 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 has a cylindrical shape extending in the left-right direction inside the handle body 21. The one wall portion 23 may be referred to as the first wall portion 23, etc.
[0041] One wall portion 23 has a support wall portion 23a protruding forward from the front end surface of the handle body 21, a body wall portion 23b extending upward from the front end portion of the support wall portion 23a, and an anti-slip protrusion 23c.
[0042] The support wall 23a is a plate extending in the front-rear direction, and a pair of plate surfaces face the up-down direction. A front portion of the support wall 23a is located forward of the front end surface of the handle body 21, and a rear portion of the support wall 23a is disposed inside the handle body 21.
[0043] The lower end of the main body wall 23b is connected to the front end of the support wall 23a. The main body wall 23b is in the form of a plate extending in a direction perpendicular to the radial direction of the cooking appliance 1, and a pair of plate surfaces face in the radial direction (front-rear direction). The main body wall 23b is in the form of a flat plate. In this embodiment, the main body wall 23b is in the form of a polygonal plate such as a rectangular plate, or a semicircular plate that is convex 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 thereto, and for example, the dimension in the up-down direction and the dimension in the left-right direction of the main body wall 23b may be approximately the same as each other, or the dimension in the left-right direction may be smaller than the dimension in the up-down direction.
[0044] In addition, as described above, when the outer wall portion 14 is formed in a curved plate shape extending in the circumferential direction around the central axis C, it is preferable that the main body wall portion 23b is formed in a curved plate shape extending in the circumferential direction so as to be in close contact with a plate surface (concave curved surface) facing radially inward of the outer wall portion 14 (see FIG. 6). That is, in this case, the plate surface facing the rear side (radially outward) of the main body wall portion 23b is formed in a convex curved surface shape extending in the circumferential direction.
[0045] The anti-slip protrusion 23c is disposed on a wall surface facing the rear side of one wall portion 23. Specifically, the anti-slip protrusion 23c protrudes rearward from a plate surface (wall surface) facing the rear side of the main body wall portion 23b. The anti-slip protrusion 23c comes into contact with a plate surface of the outer wall portion 14 facing radially inward.
[0046] In this embodiment, the anti-slip protrusions 23c are rib-shaped and extend in the left-right direction. A plurality of the anti-slip protrusions 23c are provided at intervals from each other. In this embodiment, a plurality of the rib-shaped anti-slip protrusions 23c are provided lined up in the up-down direction.
[0047] In this embodiment, the one wall 23 has a metal L-shaped plate-shaped body 23d and a rubber non-slip cover 23e that covers a part of the L-shaped plate-shaped body 23d. The non-slip cover 23e covers the area of the L-shaped plate-shaped body 23d that is disposed on the front part of the support wall 23a and the main body wall 23b. The non-slip protrusion 23c is provided on a part of the non-slip cover 23e. Specifically, the non-slip protrusion 23c is provided on a part of the non-slip cover 23e that constitutes a wall surface facing the rear side of the main body wall 23b. Therefore, the rubber non-slip protrusion 23c elastically deforms and comes into close contact with the outer wall 14, thereby providing a non-slip function and suppressing unintended sliding movement between the one wall 23 and the outer wall 14.
[0048] Of the pair of walls 23, 24, the other wall 24 located on the rear side is disposed on the front end surface of the handle body 21. The other wall 24 is a wall surface that constitutes at least a part of the front end surface of the handle body 21. The other wall 24 may also be referred to as the second wall 24, etc.
[0049] The other wall portion 24 has a pressing wall surface 24a facing forward and a step portion 24b facing downward. The pressing wall surface 24a is disposed on the upper portion of the front end surface of the handle body 21. The pressing wall surface 24a is flat and extends in a direction perpendicular to the radial direction of the cooking appliance 1. Specifically, in this embodiment, the pressing wall surface 24a is a polygonal surface such as a rectangular surface, or a semicircular surface that is convex 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 thereto, and for example, the dimensions in the up-down direction and the left-right direction of the pressing wall surface 24a may be approximately the same, or the dimension in the left-right direction may be smaller than the dimension in the up-down direction.
[0050] In addition, as described above, when the outer wall portion 14 is in the form of a curved plate extending in the circumferential direction around the central axis C, it is preferable that the pressing wall surface 24a is in the form of a curved concave surface extending in the circumferential direction so as to be in close contact with the plate surface (convex surface) facing radially outward of the outer wall portion 14 (see Figure 6).
[0051] The step portion 24b is disposed below the pressing wall surface 24a. The step portion 24b is connected to the lower end of the pressing wall surface 24a and extends rearward from the lower end. The step portion 24b is a wall surface facing downward. The step portion 24b is disposed above the support wall portion 23a and spaced apart from the support wall portion 23a.
[0052] Although not shown, the other wall portion 24 may further have a pressing protrusion protruding forward from the pressing wall surface 24a. The pressing protrusion contacts the plate surface of the outer wall portion 14 facing radially outward. Only one pressing protrusion may be provided, or multiple pressing protrusions may be provided at intervals. In this case, the pressing protrusion provides an anti-slip function, and unintended sliding movement between the other wall portion 24 and the outer wall portion 14 is suppressed.
[0053] The pair of walls 23, 24 can be moved toward or away from each other by operating an operating unit 25 described later. The outer wall 14 is inserted between the pair of walls 23, 24 that open upward from above, in the left-right direction, or in the circumferential direction about the central axis C. In other words, the mounting portion 22 is attached to the outer wall 14 from below, in the left-right direction, or in the circumferential direction about the central axis C.
[0054] As shown in Figures 2 to 7, the operating unit 25 switches the mounting portion 22 between a closed state (see Figures 2, 4 and 6) in which the outer wall portion 14 is clamped between a pair of wall portions 23, 24, and an open state (see Figures 3, 5 and 7) in which the outer wall portion 14 can be removed from between the pair of wall portions 23, 24.
[0055] In detail, as shown in Figures 4 and 5, the operating unit 25 has a lever 26 fixed to one of the pair of wall portions 23, 24 of the mounting portion 22, a locking mechanism 27 that locks the lever 26 when the mounting portion 22 is closed, and an unlocking mechanism 28 that releases the locked state of the lever 26 by the locking mechanism 27.
[0056] The lever 26 is fixed to the support wall portion 23a of the one wall portion 23. The lever 26 is rotatable around a rotation shaft 29 provided inside the handle body 21 and is supported by the handle body 21. That is, the lever 26 and the one wall portion 23 rotate integrally around the rotation shaft 29. When the user presses a portion of the lever 26 exposed to the outside of the handle (a lever body portion 26a described later) downward by, for example, gripping the detachable handle 2 with the palm of the hand in the open state of the attachment portion 22 shown in FIG. 5, the lever 26 and the one wall portion 23 rotate around the rotation shaft 29, and the attachment portion 22 enters the closed state shown in FIG.
[0057] The lever 26 has a lever main body portion 26a that is positioned on the upper part of the handle body 21 and exposed to the outside of the handle, a lever connection portion 26b that is positioned inside the handle body 21 and connects the rear portion of the support wall portion 23a to the lever main body portion 26a, and an extension portion 26c that extends from the lever main body portion 26a into the inside of the handle body 21.
[0058] The lever body 26a extends in the front-rear direction. The lever connection part 26b is made of, for example, metal, and is formed integrally with the L-shaped plate-shaped body 23d of one of the walls 23. The rear end of the lever connection part 26b is fixed to the lever body 26a. The extension part 26c is provided so as to hang down from the lever body 26a.
[0059] The locking mechanism 27 is provided inside the handle body 21. The locking mechanism 27 has a locked portion 27a provided on a part of the lever 26, and a locking portion 27b that is detachably locked to the locked portion 27a.
[0060] In this embodiment, the locked portion 27a is provided at the lower end of the extension portion 26c and has a hole shape facing forward. The locking portion 27b is provided inside the handle body 21 and has an axis or pin shape extending in the front-rear direction. The locking portion 27b is inserted into a guide hole 21a provided inside the handle body 21. The movement of the locking portion 27b in the front-rear direction is guided by the guide hole 21a.
[0061] When the user pushes lever 26 (lever main body 26a) downward and the mounting portion 22 is closed as shown in Fig. 4, the rear end of locking portion 27b is inserted into recessed locked portion 27a, and locked portion 27a and locking portion 27b are locked, thereby locking lever 26. At this time, locking mechanism 27 locks one wall portion 23 fixed to lever 26 together with lever 26. That is, locking mechanism 27 locks mounting portion 22 in the closed state.
[0062] The lock release mechanism 28 has a release main body portion 28a arranged at the bottom of the handle main body 21, and a connecting portion 28b arranged inside the handle main body 21 and rotatably connecting the release main body portion 28a and the engaging portion 27b.
[0063] A part of the release main body 28a is disposed inside the handle main body 21, and the other part (hereinafter, may be referred to as the release button) is exposed to the outside of the handle. Specifically, the release button is disposed on the underside of the handle main body 21, toward the front end. It is preferable that the release button is located forward of the portion where the user grips the detachable handle 2. The release main body 28a is supported by the handle main body 21 and is capable of swinging around a swing shaft 32 provided inside the handle main body 21. The swing shaft 32 is cylindrical and extends left and right inside the handle main body 21.
[0064] The connecting portion 28b is provided on a portion of the release main body portion 28a that is located above and rearward of the pivot shaft 32. The connecting portion 28b is connected to a front end portion of the locking portion 27b.
[0065] When the user operates the release button of the lock release mechanism 28 with the index finger or the like while gripping the detachable handle 2 in the closed state of the attachment part 22 shown in Fig. 4 (pushing it backward as shown in Fig. 3), the release main body part 28a swings around the swing shaft 32 as shown in Fig. 5, and the locking part 27b of the lock mechanism 27 connected to the connecting part 28b is pulled forward. This releases the locking state between the locking part 27b and the locked part 27a, and the locked state of the lever 26 by the lock mechanism 27 is released. When the lever 26 is unlocked, the locking of the attachment part 22 in the closed state is also released, and it becomes possible to open the attachment part 22.
[0066] The first biasing portion (biasing portion) 30 is provided on the handle main body 21 and biases the attachment portion 22 from the closed state shown in Fig. 4 to the open state shown in Fig. 5. The first biasing portion 30 is, for example, a tension coil spring or the like, and is disposed inside the handle main body 21. One end of the first biasing portion 30 is connected to the handle main body 21, and the other end of the first biasing portion 30 is connected to the lever 26 or one of the walls 23. In the illustrated example, one end of the first biasing portion 30 is connected to the front wall portion of the handle main body 21 (the rear side of the other wall portion 24), and the other end of the first biasing portion 30 is connected to the lever connection portion 26b.
[0067] The first biasing portion 30 biases the one wall portion 23 in a direction (forward) in which the one wall portion 23 moves away from the other wall portion 24. In other words, the first biasing portion 30 also biases the lever 26 from the closed state of the lever 26 shown in Fig. 4 to the open state of the lever 26 shown in Fig. 5. Specifically, the first biasing portion 30 biases the one wall portion 23 and the lever 26 so as to rotate about the rotation shaft 29 from the closed state to the open state.
[0068] Therefore, when the locked state of the lever 26 and the mounting portion 22 by the lock mechanism 27 is released by the lock release mechanism 28, the one wall portion 23 is moved away from the other wall portion 24 by the biasing force of the first biasing portion 30, and the mounting portion 22 is stably opened. Accordingly, the lever 26 is also stably opened.
[0069] In this embodiment, when the mounting portion 22 is changed from the closed state shown in FIG. 6 to the open state shown in FIG. 7, the cooking appliance 1 tilts due to its own weight, and the outer wall portion 14 is locked between the pair of walls 23, 24. In the example shown in FIG. 7, the outer wall portion 14 is hooked between one wall portion 23 and the other wall portion 24, and is locked between the pair of walls 23, 24. In detail, the connection portion between the folded portion 13 and the outer wall portion 14 abuts against the rear side of the upper end of the one wall portion 23, and the lower end side of the outer wall portion 14 abuts against the lower end side (the front end side of the step portion 24b) of the pressing wall surface 24a of the other wall portion 24, and the cooking appliance 1 is locked between the pair of walls 23, 24. In this way, the cooking appliance 1 is prevented from falling off the detachable handle 2.
[0070] Further, the second biasing portion 31 is provided on the handle main body 21, and biases the release main body portion 28a of the lock release mechanism 28 from the unlocked position shown in Fig. 5 to the locked position shown in Fig. 4. The second biasing portion 31 has a function of maintaining the lock release mechanism 28 in the locked position. The second biasing portion 31 is, for example, a tension coil spring, and is disposed inside the handle main body 21. The second biasing portion 31 is inserted into a through hole or notch (not shown) that penetrates the lever connection portion 26b in the front-rear direction.
[0071] In the illustrated example, one end of the second biasing portion 31 is connected to the rotation shaft 29. The other end of the second biasing portion 31 is connected to a portion of the release main body 28a that is located below and forward of the swing shaft 32. The second biasing portion 31 biases the release main body 28a to swing from the unlocked position to the locked position around the swing shaft 32.
[0072] 5, when the user releases the index finger or the like from the release button of the lock release mechanism 28 while pressing the release button rearward, the biasing force of the second biasing portion 31 causes the release main body 28a to swing about the swing shaft 32. Specifically, the biasing force of the second biasing portion 31 causes the release main body 28a to swing from the unlocked position to the locked position, but at this time, the biasing force of the first biasing portion 30 keeps the attachment portion 22 and the lever 26 in the open state.
[0073] In the cooking appliance 10 with a detachable handle of this embodiment described above, the cooking appliance 1, such as a frying pan, is provided with a folded portion 13 that protrudes outward from an upper opening of the side wall 12, and an outer wall portion 14 that protrudes downward from the folded portion 13. In addition, the attachment portion 22 of the detachable handle 2 has a pair of walls 23, 24 that open upward, and the outer wall portion 14 is inserted between the pair of walls 23, 24.
[0074] With outer wall portion 14 inserted between the pair of wall portions 23, 24, the user operates operation portion 25 (lever 26) to close mounting portion 22, whereby outer wall portion 14 is clamped between the pair of wall portions 23, 24 and detachable handle 2 is fixed to cooking appliance 1. In addition, when the user operates operation portion 25 (lock release mechanism 28) to open mounting portion 22, outer wall portion 14 can be removed from between the pair of wall portions 23, 24, and the fixed state between detachable handle 2 and cooking appliance 1 is released.
[0075] In this embodiment, the attachment part 22 of the detachable handle 2 is not disposed inside the side wall 12 of the cooking appliance 1, and one wall part 23 (the front wall part 23) of the pair of walls 23, 24 of the attachment part 22 is disposed between the side wall 12 and the outer wall part 14 of the cooking appliance 1, and is covered from above by the folded part 13. This prevents the detachable handle 2 from becoming soiled by the food being cooked, making it hygienic. In addition, because the detachable handle 2 is made less likely to become soiled, the process of washing the handle after use can be omitted or simplified, and it is easy to wash. When the circumferential dimension of the folded portion 13 is greater than the circumferential dimension of the outer wall portion 14, adhesion of the food to one wall portion 23 is further suppressed, and the above-mentioned effect becomes more pronounced.
[0076] Furthermore, because outer wall 14 of cooking appliance 1 is inserted between a pair of walls 23, 24 that open upward, even if a user erroneously operates operation unit 25 (lock release mechanism 28) and unintentionally switches mounting unit 22 from a closed state to an open state, cooking appliance 1 will tilt due to its own weight, making it easier for outer wall 14 to get caught on walls 23, 24. Therefore, in this embodiment, problems such as cooking appliance 1 falling due to user erroneous operation, etc. can be prevented, and safety is high.
[0077] In addition, in this embodiment, when the attachment portion 22 is in the open state, the cooking appliance 1 tilts due to its own weight, and the outer wall portion 14 is engaged between the pair of walls 23, 24. In this case, even if the user erroneously operates the operating unit 25 and the mounting unit 22 unintentionally switches from the closed state to the open state, the cooking appliance 1 will tilt due to its own weight, and the outer wall 14 will be caught between the pair of walls 23, 24, and will be locked in place. Therefore, problems such as the cooking appliance 1 falling due to user erroneous operation, etc., are more stably prevented.
[0078] In this embodiment, the folded portion 13 and the outer wall portion 14 of the cooking appliance 1 are provided at a part of the upper opening of the side wall 12 in the circumferential direction. In this case, the folded portion 13 and outer wall portion 14 provided on a portion of the circumference of the upper opening of the side wall 12 make it possible to hygienically and safely attach and detach the detachable handle 2 to the cooking appliance 1, while preventing an increase in the weight of the cooking appliance 1 as a whole and a bulkiness when stored.
[0079] In this embodiment, the side wall 12, the folded portion 13 and the outer wall portion 14 of the cooking appliance 1 are integrally formed from a single member. For example, in the case of conventional products where a bracket for mounting a handle is fixed to the side wall of a cooking appliance by welding and a removable handle is attached to this bracket, welding marks are generated on the surface facing the inside of the side wall (inner surface), which makes the cooking appliance look bad, and dirt from the cooking ingredients accumulates in the unevenness of the welding marks. Also, when the bracket is fixed to the side wall of a cooking appliance by screws or rivets, the appearance of the cooking appliance is marred and dirt is likely to accumulate in the unevenness of the screws or rivets (see, for example, Patent Publication No. 3232034, etc.).
[0080] In contrast, in the above-described configuration of this embodiment, the side wall 12, folded portion 13, and outer wall portion 14 of the cooking device 1 are integrally formed from a single member, so that when the folded portion 13 and outer wall portion 14 are provided on the side wall 12, the appearance of the cooking device 1 is not marred by welding marks, screws, rivets, etc. This results in an aesthetically pleasing exterior design of the cooking device 1. Also, since there are no projections or recesses on the side wall 12 of the cooking device 1, food does not accumulate and become dirty, making it hygienic. Furthermore, since the welding and riveting processes are not required, the manufacturing of the cooking device 1 is facilitated and the manufacturing costs are reduced.
[0081] However, in the present invention, the folded portion 13 and the outer wall portion 14 of the cooking device 1 are not necessarily limited to being formed without welding as described above. For example, a member having the shape of the folded portion 13 and the outer wall portion 14 may be formed, and the upper end portion of the side wall 12 of the cooking device 1 and the inner circumferential side of the folded portion 13 may be welded together to form them as a single unit. In the former method, the folded portion 13 and the outer wall portion 14 of the cooking device 1 can be formed as a single unit by, for example, casting, and in the latter method, the folded portion 13 and the outer wall portion 14 of the cooking device 1 can be formed as a single unit by pressing and welding. In other words, the optimal method may be selected by considering the manufacturing cost, manufacturing process, and appearance of the finished product, etc.
[0082] In addition, in this embodiment, the operating portion 25 has a lever 26 fixed to one of the pair of wall portions 23, 24 of the mounting portion 22, a locking mechanism 27 that locks the lever 26 when the mounting portion 22 is in the closed state, and an unlocking mechanism 28 that releases the locked state of the lever 26 by the locking mechanism 27. In this case, when the user operates the lever 26, one wall 23 (the front wall 23) approaches the other wall 24 (the rear wall 24), so that the outer wall 14 is sandwiched between the pair of walls 23, 24. This allows the cooking appliance 1 to be held by the detachable handle 2.
[0083] Furthermore, in this state (the attachment portion 22 is closed), the lever 26 is locked by the locking mechanism 27, so that the attachment portion 22 is stably maintained in the closed state. This prevents the detachable handle 2 from unintentionally coming off the cooking appliance 1. In this embodiment, the user normally holds the detachable handle 2 (handle body 21) with the palm of his / her hand, which keeps the lever 26 in the closed state, and the lever 26 is not unlocked. Therefore, even if the user uses the device incorrectly, it prevents the detachable handle 2 from unintentionally coming off the cooking appliance 1 and the cooking appliance 1 from falling off the detachable handle 2, and functions as a double safety mechanism.
[0084] Furthermore, when the user operates the lock release mechanism 28 to release the locked state of the lever 26, the one wall portion 23 can be separated from the other wall portion 24, and the outer wall portion 14 can be removed from between the pair of walls 23, 24. This allows the detachable handle 2 to be removed from the cooking appliance 1.
[0085] In this embodiment, the detachable handle 2 has a first biasing portion 30 that is provided on the handle body 21 and biases the attachment portion 22 from the closed state to the open state. In this case, when the locked state of the lever 26 is released by the lock release mechanism 28, the first biasing portion 30 returns the mounting portion 22 from the closed state to the open state. This makes it easy to remove the outer wall portion 14 from between the pair of walls 23, 24, and also makes it easy to insert the outer wall portion 14 between the open pair of walls 23, 24 the next time the detachable handle 2 is attached to the cooking appliance 1. This makes the cooking appliance 10 with a detachable handle easy to use.
[0086] In this embodiment, the second biasing portion 31 maintains the lock release mechanism 28 in the locked position by its biasing force. In this case, the second biasing portion 31 prevents the lock release mechanism 28 from unintentionally switching from the locked position to the unlocked position. This also prevents the attachment portion 22 from unintentionally switching from the closed state to the open state.
[0087] The present invention is not limited to the above-described embodiment, and the configuration may be modified within the scope of the present invention, as described below. In the illustration of the modified example, the same reference numerals are used for the same configuration as the above-described embodiment, and the following mainly describes the differences.
[0088] 8 is a side cross-sectional view showing a part of a cooking appliance 20 with a detachable handle according to a first modified example of the embodiment described above, showing an open state of the attachment part 22. In this first modified example, the outer wall part 14 has a flange part 14a that protrudes outward from the lower end part of the outer wall part 14. In this case, even if the user erroneously operates the operation unit 25 (unlock mechanism 28) and the mounting unit 22 unintentionally switches from the closed state to the open state, the cooking appliance 1 will tilt due to its own weight, and the flange 14a of the outer wall 14 will be more likely to come into contact with the other wall 24 (rear wall 24) of the pair of walls 23, 24. This further reduces the occurrence of problems such as the cooking appliance 1 falling due to a user's erroneous operation, etc.
[0089] In the first modified example, the step portion 24b of the other wall portion 24 faces the flange portion 14a from above. 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 comes into contact with and gets caught on the step portion 24b of the other wall portion 24 (the rear wall portion 24) from below. This more stably prevents the cooking appliance 1 from falling due to a user's erroneous operation or the like.
[0090] Fig. 9 is a side cross-sectional view showing a portion of cooker 40 with a detachable handle according to a second modified example of the embodiment described above, showing the open state of attachment part 22. Fig. 10 is a side cross-sectional view showing a portion of cooker 50 with a detachable handle according to a third modified example of the embodiment described above, showing the open state of attachment part 22.
[0091] In the second modified cooking appliance with a detachable handle 40, the length (radial dimension) of the folded portion 13 is shorter than in the above embodiment, and the distance (radial dimension) between the outer wall portion 14 and the side wall 12 is narrower. In the third modified cooking appliance with a detachable handle 50, the distance between the one wall portion 23 and the other wall portion 24 is wider than in the above embodiment. In these second and third modified cooking appliances, when the attachment portion 22 is in the open state, the cooking appliance 1 tilts due to its own weight, and one wall portion 23 of the pair of walls 23, 24 is engaged between the outer wall portion 14 and the side wall 12. Note that in Figures 9 and 10, the outer wall portion 14 is not in contact with the other wall portion 24 of the attachment portion 22. In this case, even if the user erroneously operates the operation unit 25 (lock release mechanism 28) and the mounting unit 22 unintentionally switches from the closed state to the open state, the cooking appliance 1 will tilt due to its own weight, and one wall 23 (the front wall 23) of the pair of walls 23, 24 will get caught between the outer wall 14 and the side wall 12, thereby being locked in place. Therefore, problems such as the cooking appliance 1 falling due to user erroneous operation, etc., are stably prevented.
[0092] 11 is a perspective view showing cooker 1 of cooker 60 with a detachable handle according to a fourth modified example of the embodiment described above. In this fourth modified example, cooker 1 is, for example, a pot or the like. That is, the vertical dimension (depth dimension) of cooker 1 may be shallow or deep. Also, in this fourth modified example, folded portion 13 and outer wall portion 14 are provided around the entire circumferential circumference of the upper opening of side wall 12. In this case, when attaching the detachable handle 2 to the cooking appliance 1, it can be attached from any position in the circumferential direction, which provides a high degree of freedom and makes it easier to use.
[0093] In the above-described embodiment and each modified example, the structure is shown in which the other wall portion 24 on the rear side of the pair of walls 23, 24 is fixed, and the one wall portion 23 on the front side moves, so that the outer wall portion 14 is engaged between the pair of walls 23, 24. However, the present invention is not limited to this, and the one wall portion 23 on the front side of the pair of walls 23, 24 may be fixed, and the other wall portion 24 on the rear side may slide back and forth or rotate, so that the outer wall portion 14 is engaged between the pair of walls 23, 24, and the cooking appliance 1 may be detachable from the detachable handle 2. Specifically, the one wall portion 23 may be fixed to the handle main body 21, and the other wall portion 24 may move relative to the handle main body 21 and the one wall portion 23, so that the one wall portion 23 and the other wall portion 24 can approach or move away from each other.
[0094] In that case, it is also possible to configure the support wall 23a and main body wall 23b on the one wall 23 side to be made of metal, and the other wall 24 side to be provided with a rubber anti-slip cover. That is, instead of providing the anti-slip cover on the one wall 23, it is also possible to provide the anti-slip cover on the other wall 24. In this way, the metal support wall 23a is present below the other wall 24, and the rubber anti-slip cover, which has a lower heat resistance than metal, is not exposed downward, so that it is possible to protect the rubber anti-slip cover (the other wall 24) from the stove fire during cooking, thereby improving safety.
[0095] Although not specifically shown, cooking appliance 1 is not limited to a bottomed cylindrical shape centered on central axis C, and may be, for example, a bottomed polygonal cylindrical shape such as a bottomed square cylindrical shape.
[0096] The present invention may be combined with the various configurations described in the above-mentioned embodiments and modifications, and may include additions, omissions, substitutions, and other modifications, without departing from the spirit of the present invention. The present invention is not limited to the above-mentioned embodiments, but is limited only by the claims. [Explanation of symbols]
