Abstract
Description
[Technical Field]
[0001] The present invention relates to the technical field of an openable hot plate having a first cooking plate and a second cooking plate. [Background technology]
[0002] Hot plates are electric cookers that use a heater to heat the cooking plate from the back side to cook food. Some hot plates have a foldable (openable and closable) first and second body parts, and cooking is performed with the first and second body parts open (see, for example, Patent Document 1).
[0003] In the hot plate described in Patent Document 1, cooking can be performed by heating a first cooking plate provided on a first main body with a heater, and cooking can be performed by heating a second cooking plate provided on a second main body with a separate heater. Therefore, cooking can be performed using both the first cooking plate and the second cooking plate simultaneously, improving convenience during cooking. [Prior art documents] [Patent documents]
[0004] [Patent Document 1] Japanese Patent Publication No. 2020-44444 Summary of the Invention [Problem to be solved by the invention]
[0005] Incidentally, a hot plate having a first cooking plate and a second cooking plate as described in Patent Document 1 is highly convenient because it allows cooking to be done using the first cooking plate and the second cooking plate simultaneously, but it tends to be large because it has the first cooking plate and the second cooking plate.
[0006] In particular, hot plates are stored in a closed state when not in use, and if the overall thickness is large when closed, this may reduce storage capacity.
[0007] SUMMARY OF THE INVENTION Therefore, an object of the present invention is to make the case thinner when closed and ensure good storage properties. [Means for solving the problem]
[0008] The hot plate of the present invention comprises a main body having a first cooking plate, and a lid body having a second cooking plate and adapted to be opened and closed relative to the main body using a fulcrum axis as a fulcrum between a closed position and an open position, wherein the first cooking plate has a first cooking surface portion on which an item to be cooked is placed and a first standing wall portion covering the first cooking surface portion from the outer periphery, and the second cooking plate has a second cooking surface portion on which an item to be cooked is placed and a second standing wall portion covering the second cooking surface portion from the outer periphery, and when the lid body is in the closed position, at least a portion of the second cooking plate or at least a portion of the first cooking plate is inserted inside the first standing wall portion or the second standing wall portion.
[0009] This reduces the overall thickness of the first cooking plate and the second cooking plate when the lid is in the closed position. [Effects of the Invention]
[0010] According to the present invention, the overall thickness of the first cooking plate and the second cooking plate is reduced when the lid body is in the closed position, thereby achieving a slimmer design when closed and ensuring good storage properties. [Brief explanation of the drawings]

[0012] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A hot plate according to an embodiment of the present invention will now be described with reference to the accompanying drawings.
[0013] The hot plate described below has a main body and a lid, the lid being openable and closable relative to the main body, and two movable legs rotatably supported on the lid. In the following description of the hot plate, the front, back, up, down, left, and right directions will be described with the lid closed and the main body placed on a table or other support surface. Therefore, the side where the lid is located is referred to as the upper side, the side where the main body is located is referred to as the lower side, and the direction in which the two movable legs are aligned is referred to as the left-right direction. However, the front, back, up, down, left, and right directions described below are for the sake of convenience, and the practice of the present invention is not limited to these directions.
[0014] <Hot plate configuration> (Overall schematic configuration) Hot plate 1 has a main body 2, a lid 3, and movable legs 4 (see FIGS. 1 to 4). When lid 3 is closed, hot plate 1 is formed as a flat block overall, with a planar shape that is generally rectangular, for example, generally square. Therefore, the outer surface of hot plate 1 has a first flat surface 5 facing upward, a second flat surface 6 facing downward, and an outer peripheral surface 7 positioned between the first flat surface 5 and the second flat surface 6, and outer peripheral surface 7 has four surfaces facing forward, backward, left, and right.
[0015] The four surfaces of the outer peripheral surface 7 are formed as two first side surfaces 7a located at the front and rear and two second side surfaces 7b located at the left and right. The portions of the outer peripheral surface between the first side surface 7a and the second side surface 7b are formed as curved surfaces 7c that are continuous with the first side surface 7a and the second side surface 7b, respectively.
[0016] Therefore, hot plate 1 has four curved surfaces 7c, and by forming hot plate 1 into a shape with four curved surfaces 7c, it does not have an angular shape, and is formed into a shape that is high in strength and does not cause discomfort when touched by the hand, such as pain. Also, hot plate 1 is formed into a flat block shape overall, and by forming it into a shape with four curved surfaces 7c, it has a high designability.
[0017] (Main body configuration) The main body 2 has a first housing 8 formed in a box shape that opens upward, a first heater (not shown) arranged inside the first housing 8, and a first cooking plate 9 attached to the first housing 8.
[0018] The first housing 8 has a bottom surface 10 facing in the vertical direction, a peripheral surface 11 protruding upward from the outer periphery of the bottom surface 10, and a pair of connecting protrusions 12 protruding from one side of the peripheral surface 11. The lower surface 10a of the bottom surface 10 corresponds to the second plane 6.
[0019] The first housing 8 is provided with a plurality of legs 13 protruding downward from the bottom surface 10 (see FIG. 4). The legs 13 protrude, for example, from the four corners of the bottom surface 10, and when the main body 2 is placed on a placement surface (upper surface) 100 such as a table, the legs 13 are placed on the placement surface 100 and have the function of holding the main body 2 in a stable state.
[0020] A plug accommodating section 14 that opens downward is formed on the lower surface 10a side of the bottom surface section 10. A pair of terminal holding sections 15 are provided at one end of the plug accommodating section 14 of the bottom surface section 10. A cord winding section 16 that protrudes downward is provided on the lower surface 10a side of the bottom surface section 10.
[0021] A first heater substrate (not shown) is disposed inside the main body 2, and the first heater is controlled by a control circuit formed on the first heater substrate. One end of a power cord 80 is connected to the first heater substrate.
[0022] When hot plate 1 is not in use, cable 81 of power cord 80 can be wound and held around cord winding portion 16. By winding and holding cable 81 around cord winding portion 16, cable 81 does not get in the way when hot plate 1 is not in use (stored), and cable 81 can be protected and hot plate 1 can be stored in a good condition.
[0023] Furthermore, when hot plate 1 is not in use, plug portion 82 of power cord 80 can be accommodated in plug accommodating portion 14, and the pair of terminals of plug portion 82 can be inserted and held in terminal holding portion 15. By accommodating plug portion 82 in plug accommodating portion 14 and inserting the pair of terminals into terminal holding portion 15, plug portion 82 does not get in the way when hot plate 1 is not in use (stored), and plug portion 82 can be protected and the hot plate 1 can be kept in a good stored state.
[0024] When using the hot plate 1, the pair of terminals are pulled out from the terminal holding portion 15, the plug portion 82 is removed from the plug accommodating portion 14, the cable 81 is unwound from the cord winding portion 16, and the power cord 80 is pulled out from the gap between the bottom portion 10 and the placing surface 100, thereby connecting the plug portion 82 to a commercial power source.
[0025] The peripheral surface portion 11 is composed of a first wall portion 17 and a second wall portion 18 positioned in the front and rear, a third wall portion 19 and a fourth wall portion 20 positioned in the left and right, and four curved wall portions 21 positioned between each wall portion (see FIGS. 1 and 2). The outer surface of the first wall portion 17 is formed as a first outer surface 17a, the outer surface of the second wall portion 18 is formed as a second outer surface 18a, the outer surface of the third wall portion 19 is formed as a third outer surface 19a, and the outer surface of the fourth wall portion 20 is formed as a fourth outer surface 20a. The first outer surface 17a, the second outer surface 18a, the third outer surface 19a, and the fourth outer surface 20a are all formed as flat surfaces.
[0026] First wall 17 has a recess 22 that opens forward (see FIG. 1). Main body 2 is provided with a selector switch 23, which is located in recess 22 and does not protrude outward (forward) from first outer surface 17a. Operating selector switch 23 allows for three different modes to be selected, including a power-off mode, a first heating mode in which first cooking plate 9 is heated, and a second heating mode in which both first cooking plate 9 and a second cooking plate (described later) are heated.
[0027] A pair of mounting ribs 24 are provided on the second wall portion 18, spaced apart from each other on the left and right sides, protruding slightly outward (rearward) from the second outer surface 18a (see FIG. 2). The mounting ribs 24 are formed, for example, in a linear shape extending vertically.
[0028] A shaft insertion hole 25 extending in the front-rear direction is formed in the third wall portion 19 (see FIG. 1). A slide knob 26 is provided on the main body 2, and the slide knob 26 is positioned outside the third outer surface 19a while connected to a connecting shaft (not shown) that is inserted into the shaft insertion hole 25. By operating the slide knob 26, it is possible to adjust the heating temperature of the first heater. The slide knob 26 is provided as a protrusion that protrudes outward (laterally) from one of the second side surfaces 7b.
[0029] A display unit 27 is disposed on the third wall portion 19. The display state of the display unit 27 is changed by operating the changeover switch 23 or the slide knob 26, and the user can recognize the usage state by visually checking the display state of the display unit 27.
[0030] The fourth wall 20 has a protrusion 28 that protrudes outward from the fourth outer surface 20a (see FIG. 2). Therefore, the protrusion 28 is provided as a protrusion that protrudes outward (laterally) from the other second side surface 7b.
[0031] For example, the outer surface 28a of the protrusion 28 is formed in a curved shape. An interference prevention notch 29 that opens upward and to the side (outward) is formed on the upper side of the protrusion 28 in the fourth wall 20 (see FIG. 5). Therefore, the interference prevention notch 29 is formed by a first notch-forming surface 29a facing laterally and a second notch-forming surface 29b facing upward.
[0032] A pair of locking portions 30 projecting laterally are provided on the fourth wall portion 20, spaced apart from each other in the front and rear (see FIGS. 5 and 6). The locking portions 30 project laterally from the upper end of the first notch-forming surface 29a. The locking portions 30 have an engagement surface 30a, a flat surface 30b, and a curved surface 30c as parts of their outer circumferential surface. The engagement surface 30a is formed as a surface facing downward, the flat surface 30b is formed as a surface facing laterally and continuing from the outer edge of the engagement surface 30a, and the curved surface 30c is formed as a surface that is convex upward and continues from the upper edge of the flat surface 30b on the opposite side of the engagement surface 30a with the flat surface 30b in between.
[0033] A pair of connecting protrusions 12 are provided spaced apart in the front and rear and protrude from the fourth wall portion 20 (see FIGS. 3, 5, and 6). A portion of each connecting protrusion 12 is positioned in the interference prevention notch 29, and is provided, for example, at a position immediately inside each of the pair of locking portions 30 in the front-to-rear direction. A support hole 12a that opens to the front or rear is formed in each connecting protrusion 12, and the support hole 12a is formed, for example, in the shape of an oblong hole that is long in the vertical direction.
[0034] The first cooking plate 9 is attached to the first housing 8 (see FIG. 3). Note that the first cooking plate 9 may be detachable from the first housing 8.
[0035] The first cooking plate 9 is attached to the first housing 8 facing the first heater, and has a first cooking surface 31 that is a plate-like plate facing up and down, a first standing wall 32 that protrudes from the outer periphery of the first cooking surface 31, and a first flange 33 that protrudes outward from the tip of the first standing wall 32 (see Figures 3 and 7). The first cooking plate 9 is attached to the first housing 8 with the first cooking surface 31 and the first standing wall 32 inserted inside the first housing 8, and the portion of the first cooking plate 9 other than the first flange 33 positioned inside the first housing 8.
[0036] The first cooking surface 31 is formed in a generally rectangular shape that is slightly smaller than the outer shape of the first housing 8, and the first standing wall 32 is gently inclined so as to displace outward as it approaches the first flange 33 from the first cooking surface 31 (see FIG. 7). Therefore, the size of the inner circumferential surface of the part of the first standing wall 32 that continues to the first flange 33 is slightly larger than the size of the inner circumferential surface of the part that continues to the first cooking surface 31.
[0037] (Lid configuration) The lid 3 has a second housing 34 formed in a box shape that opens downward, a second heater (not shown) disposed inside the second housing 34, and a second cooking plate 35 that is, for example, detachable from the second housing 34 (see FIGS. 1 to 4). The thickness (vertical width) of the lid 3 is smaller than the thickness of the main body 2, and the weight of the lid 3 is lighter than the main body 2. Therefore, the lid 3 is lighter than the main body 2.
[0038] The second housing 34 has a bottom portion 36 facing in the vertical direction, an outer periphery 37 protruding downward from the outer periphery of the bottom portion 36, and a pair of protruding connecting portions 38 protruding from one side of the outer periphery 37. The thickness of the second housing 34 is thinner than the thickness of the first housing 8. An upper surface 36a of the bottom portion 36 corresponds to the first plane 5.
[0039] The bottom 36 has storage recesses 39 formed on the left and right sides, spaced apart from each other (see FIG. 4). The storage recesses 39 are formed in positions ranging from both left and right ends of the bottom 36 to both left and right ends of the front and rear ends. Of the surfaces forming the storage recesses 39, the surface facing upward is formed as a hole forming surface 39a, and the surfaces facing sideways, which are continuous with both longitudinal end edges of the hole forming surface 39a, are formed as sliding surfaces 39b (see FIG. 8).
[0040] Two lock holes 40 and two protrusion insertion holes 41 are formed in the bottom portion 36. The lock holes 40 and the protrusion insertion holes 41 are opened in the hole forming surface 39a in the vicinity of the sliding surface 39b, and the lock holes 40 are formed in a position closer to the sliding surface 39b than the protrusion insertion holes 41.
[0041] The outer peripheral portion 37 is composed of a first wall portion 42 and a second wall portion 43 positioned in the front and rear, a third wall portion 44 and a fourth wall portion 45 positioned on the left and right, and four curved wall portions 46 positioned between each wall portion (see FIGS. 1 and 2). The outer surface of the first wall portion 42 is formed as a first outer surface 42a, the outer surface of the second wall portion 43 is formed as a second outer surface 43a, the outer surface of the third wall portion 44 is formed as a third outer surface 44a, and the outer surface of the fourth wall portion 45 is formed as a fourth outer surface 45a. The first outer surface 42a, the second outer surface 43a, the third outer surface 44a, and the fourth outer surface 45a are all formed as flat surfaces.
[0042] In hot plate 1, the front first side surface 7a of outer peripheral surface 7 is formed by first outer surface 17a of first housing 8 and first outer surface 42a of second housing 34, and the rear first side surface 7a of outer peripheral surface 7 is formed by second outer surface 18a of first housing 8 and second outer surface 43a of second housing 34. In addition, the left second side surface 7b of outer peripheral surface 7 is formed by third outer surface 19a of first housing 8 and third outer surface 44a of second housing 34, and the right second side surface 7b of outer peripheral surface 7 is formed by fourth outer surface 20a of first housing 8 and fourth outer surface 45a of second housing 34.
[0043] A pair of mounting ribs 47 are provided on the second wall 43, spaced apart from each other on the left and right sides, protruding slightly outward (rearward) from the second outer surface 43a (see FIG. 2). The mounting ribs 47 are formed, for example, in a linear shape extending vertically, and are positioned directly above the mounting rib 24 provided on the second wall 18 of the first housing 8.
[0044] An unlock button 48 is disposed inside the third wall portion 44 (see FIGS. 1 and 9). The unlock button 48 is connected to a lock member 49 located inside the second housing 34. The unlock button 48 and the lock member 49 are biased in the left-right direction toward the third outer surface 44a by a biasing spring (not shown), and when the unlock button 48 is not operated, the outer surface is positioned on the same plane as the third outer surface 44a.
[0045] The fourth wall portion 45 is formed with an interference prevention notch 50 that is open downward and to the side (outward) (see FIG. 5).
[0046] A pair of insertion portions 51 are provided at the front and rear of the fourth wall portion 45, spaced apart from each other (see FIGS. 9 and 10). The insertion portions 51 are formed with insertion openings 51a that open to the third wall portion 44 side.
[0047] A pair of protruding connecting portions 38 are provided spaced apart in the front and rear and protrude from the fourth wall portion 45 (see FIGS. 3, 5, 6, and 10). Each protruding connecting portion 38 is provided directly to the side of the insertion portion 51. Each protruding connecting portion 38 is positioned on both the front and rear sides of the interference prevention notch 50 and has an acted upon portion 52. The acted upon portion 52 has a guided portion 52a and a locked portion 52b that are provided continuously, and the locked portion 52b is positioned closer to the insertion portion 51 than the guided portion 52a (see FIGS. 6 and 10).
[0048] The outer peripheral surface of the protruding connecting portion 38 that continues to the locked portion 52b is formed as a slidable surface 38a, and the slidable surface 38a is continued to the fourth outer surface 45a on the side opposite to the locked portion 52b.
[0049] A fulcrum shaft 53 is provided on each of the protruding connecting portions 38 (see FIGS. 5 and 6). The two fulcrum shafts 53 are formed in a shape that extends in the front-rear direction, and protrude in directions that approach each other.
[0050] The lid 3 is connected to the main body 2 by inserting two fulcrum shafts 53 into the support holes 12a of the connecting protrusions 12, and can be opened and closed (rotated) with respect to the main body 2 between a closed position and an open position, with the fulcrum shafts 53 as the fulcrum. The closed position is a position where the lid 3 overlaps the main body 2 (see Figures 1 and 2), and the open position is a position where the lid 3 is opened 180 degrees with respect to the main body 2 (see Figures 3 and 4).
[0051] When the cover body 3 is connected to the main body 2, the two connecting protrusions 12 are positioned inside the two protruding connecting portions 38, and the two acted upon portions 52 are slidable or engageable with the two locking portions 30 of the main body 2, respectively (see Figure 6).
[0052] The second cooking plate 35 is attached to the second housing 34 facing the second heater, and has a plate-like second cooking surface 54 facing up and down, a second standing wall 55 protruding from the outer periphery of the second cooking surface 54, a continuous wall 56 protruding from the outer periphery of the second cooking surface 54, and a second flange 57 extending outward from the tip of the continuous wall 56. The continuous wall 56 and the second flange 57 protrude in substantially opposite directions from the outer periphery of the second cooking surface 54 (see Figures 3 and 7).
[0053] Second cooking plate 35 is provided with, for example, two inserted protrusions 58 spaced apart in the front and rear, protruding laterally (outward) from second flange 57. Second cooking plate 35 is provided with mounting bosses 59 protruding from second cooking surface 54 in substantially the same direction as continuous wall 56. Mounting boss 59 is located near continuous wall 56 on the opposite side in the left-right direction from the side on which inserted protrusions 58 are located.
[0054] An elastically deformable locked member 60 is attached to the mounting boss 59 by, for example, screwing.
[0055] The second cooking surface 54 is formed in a generally rectangular shape that is slightly smaller than the outer shape of the second housing 34, and the second standing wall 55 and the continuous wall 56 are positioned one above the other. The second standing wall 55 and the continuous wall 56 are gently inclined inward in the vertical direction as they move away from the second flange 57 (see FIG. 7). Therefore, the size of the inner circumferential surface of the second standing wall 55 where it connects to the second flange 57 is slightly larger than the size of the inner circumferential surface of the part where it connects to the second cooking surface 54, and the size of the inner circumferential surface of the continuous wall 56 where it connects to the second cooking surface 54 is slightly larger than the size of the inner circumferential surface at the tip.
[0056] The height of the second standing wall portion 55 is lower than the height of the first standing wall portion 32 on the first cooking plate 9, and the outer periphery of the second standing wall portion 55 and the continuous wall portion 56 is slightly smaller than the inner periphery of the first standing wall portion 32 on the first cooking plate 9.
[0057] The pair of insertion protrusions 58 of the second cooking plate 35 are inserted into the insertion openings 51a of the insertion portion 51 of the second housing 34. The second cooking plate 35 is attached to the second housing 34 by positioning the portion of the second cooking plate 35 other than the second flange portion 57 inside the second housing 34 and locking the locked member 60 with the locking member 49 connected to the unlock button 48.
[0058] On the other hand, when the second cooking plate 35 is attached to the second housing 34, pressing the unlock button 48 against the force of the spring releases the lock on the locked member 60 by the locking member 49, and the second cooking plate 35 can be removed from the second housing 34 by pulling the inserted protrusion 58 out of the insertion portion 51.
[0059] (Configuration of movable legs) The movable legs 4 are provided, for example, in two, spaced apart on the left and right, and are configured to be able to be housed in a housing recess 39 formed in the cover 3, and are formed in the same shape as the housing recess 39 (see FIGS. 1 to 4). However, it is also possible to provide one movable leg 4.
[0060] The movable leg 4 has a support portion 61 extending in the front-rear direction and a pair of supported portions 62 connected to both front and rear ends of the support portion 61, and the supported portions 62 are formed in a shape that extends in a direction perpendicular to the support portion 61. The boundary portion between the support portion 61 and the supported portions 62 is provided as, for example, a curved portion.
[0061] The support portion 61 has a gripping recess 61a formed in the center in the longitudinal direction.
[0062] The movable leg 4 is provided with a rotation shaft 63 that protrudes forward or backward from the tip of the supported portion 62 (see FIG. 8). The movable leg 4 is supported by the cover 3 so as to be rotatable between a first rotation position (see FIGS. 1 and 2) and a second rotation position (see FIGS. 3 and 4) with the rotation shaft 63 as a fulcrum. The rotation shaft 63 is inserted into a support hole (not shown) formed in the cover 3.
[0063] The two movable legs 4 rotate in opposite directions between the first rotation position and the second rotation position, and are rotated in opposite directions when rotated from the first rotation position to the second rotation position, and are also rotated in opposite directions when rotated from the second rotation position to the first rotation position.
[0064] The first rotation position is a position where the movable leg 4 is closed relative to the cover body 3 and accommodated in the accommodation recess 39, and the second rotation position is a position where the movable leg 4 is open relative to the cover body 3 and rotated approximately 90 degrees from the first rotation position.
[0065] As described above, by rotating the two movable legs 4 in opposite directions, it becomes possible to form storage recesses 39 in which the movable legs 4 are accommodated at both left and right ends of the cover body 3, and it becomes possible to position the support portions 61 at both left and right ends of the cover body 3 when accommodated in the storage recesses 39.
[0066] Therefore, when the movable leg 4 is accommodated in the accommodation recess 39, no parts of the cover body 3 are present on either the left or right side of the support portion 61, and only a part of the cover body 3 is present on one of the left and right sides of the support portion 61, making it easy to remove the movable leg 4 from the accommodation recess 39 and to rotate it easily from the first rotation position to the second rotation position.
[0067] A protrusion insertion hole 62a is formed in one supported portion 62 of the movable leg 4 (see FIG. 8). A mechanism arrangement space 62b is formed inside the one supported portion 62, and the protrusion insertion hole 62a is connected to the mechanism arrangement space 62b. A locking mechanism 64 is attached to the one supported portion 62 of the movable leg 4 in which the protrusion insertion hole 62a is formed.
[0068] The locking mechanism 64 is composed of a locking member 65 and a spring member 66 .
[0069] The locking member 65 has a plate-shaped slide portion 67 extending in a predetermined direction and an operating protrusion 68 protruding from the middle of the slide portion 67, with one end of the slide portion 67 in the longitudinal direction being provided as a spring support portion 67a and the other end of the slide portion 67 in the longitudinal direction being provided as an insertion portion 67b.
[0070] The locking member 65 has the slide portion 67 disposed in the mechanism arrangement space 62b except for the insertion portion 67b, and the operation protrusion 68 inserted into the protrusion insertion hole 62a. The locking member 65 is supported by the supported portion 62 so as to be slidable in the longitudinal direction of the slide portion 67 (the longitudinal direction of the supported portion 62).
[0071] For example, a compression coil spring is used as the spring member 66. The spring member 66 is arranged in the mechanism arrangement space 62b, with one end pressed against a predetermined surface of the supported portion 62 and the other end supported by the spring support portion 67a. Therefore, the locking member 65 is urged by the urging force of the spring member 66 in a direction in which the insertion portion 67b protrudes from the supported portion 62.
[0072] <Operation on a hot plate> When the hot plate 1 configured as described above is not in use, the lid 3 and the main body 2 are folded and closed, the lid 3 is in the closed position, and the movable legs 4 are housed in the housing recesses 39 and held in the first pivot position (see FIGS. 1 and 2). At this time, when the main body 2 is placed on the mounting surface 100, the lid 3 is placed over the main body 2, and the first cooking surface 31 of the first cooking plate 9 and the second cooking surface 54 of the second cooking plate 35 face each other vertically.
[0073] When the lid 3 is in the closed position, at least a portion of the second cooking plate 35 is inserted from above inside the first standing wall 32 of the first cooking plate 9 (see FIG. 11). Specifically, for example, the first flange 33 of the first cooking plate 9 and the second flange 57 of the second cooking plate 35 are overlapped or adjacent to each other, and the second cooking surface 54, second standing wall 55, and continuous wall 56 of the second cooking plate 35 are entirely inserted inside the first standing wall 32. At this time, the tip of the second standing wall 55 is not in contact with the upper surface of the first cooking surface 31, preventing the second standing wall 55 and the first cooking surface 31 from being damaged.
[0074] Furthermore, in the hot plate 1, the size of the inner circumference of the second standing wall portion 55 may be slightly larger than the size of the outer circumference of the first standing wall portion 32, so that at least a portion of the first standing wall portion 32 is inserted inside the second standing wall portion 55 when the lid body 3 is in the closed position.
[0075] When the movable leg 4 is accommodated in the accommodation recess 39 and held in the first rotation position, the movable leg 4 is in a state in which it does not protrude upward from the upper surface 36a of the cover 3 and does not protrude outward from the outer peripheral portion 37 of the cover 3 (see FIGS. 1, 2, and 8). At this time, the locking member 65 supported by the movable leg 4 has the operation protrusion 68 inserted into the protrusion insertion hole 41 formed in the cover 3, and the insertion portion 67b is pressed against the sliding surface 39b that forms the accommodation recess 39 by the biasing force of the spring member 66 (see FIG. 8). The insertion portion 67b of the locking member 65 is pressed against the sliding surface 39b, thereby holding the movable leg 4 in the first rotation position.
[0076] When cooking using the hot plate 1, it is desirable to first rotate the two movable legs 4 from the first rotation position to the second rotation position with the lid 3 in the closed position. When rotating the movable legs 4 from the first rotation position to the second rotation position, the user can insert the tips of their fingers into the gripping recesses 61a of the support parts 61 to lift and rotate the movable legs 4, making it easier to rotate the movable legs 4.
[0077] When the movable leg 4 is rotated from the first rotation position to the second rotation position, the insertion portion 67b of the locking member 65 slides from the sliding surface 39b to the hole forming surface 39a, and the operating protrusion 68 is pulled out from the protrusion insertion hole 41 (see Figure 12).
[0078] When the movable leg 4 is further rotated toward the second rotation position, the insertion portion 67b of the locking member 65 is inserted into the lock hole 40 by the biasing force of the spring member 66, and the movable leg 4 reaches the second rotation position (see FIG. 13). The movable leg 4 is rotated from the first rotation position to an angle of 90 degrees or slightly more than 90 degrees to reach the second rotation position, and the insertion portion 67b is inserted into the lock hole 40, thereby locking the movable leg 4 to the cover 3 at the second rotation position.
[0079] Next, with the two movable legs 4 rotated to the second rotation position, the lid 3 is opened from the closed position to the open position (see FIG. 14). The hot plate 1 does not have a locking mechanism for locking the lid 3 to the main body 2, so the lid 3 can be quickly and easily opened to the open position without the need for unlocking. In addition, by grasping the movable leg 4 farthest from the fulcrum shaft 53 and lifting and opening the lid 3, the lid 3 can be easily opened to the open position with little force.
[0080] As described above, hot plate 1 is provided with movable legs 4 that are rotatably supported on lid 3 and rotate between a first rotation position and a second rotation position. Therefore, movable legs 4 that have been rotated relative to lid 3 can be grasped with hand 90 and used as a handle to open lid 3, allowing lid 3 to be easily and reliably opened to the open position and improving the functionality of movable legs 4.
[0081] In particular, in the hot plate 1, as described above, the thickness of the lid body 3 is thinner than the thickness of the main body 2, making the lid body 3 lightweight, so that the lid body 3 can be easily and quickly opened to the open position with little force.
[0082] As described above, when the lid 3 is opened from the closed position to the open position, the interference prevention notch 29 formed in the main body 2 prevents the protruding connecting portion 38 provided on the lid 3 from contacting the main body 2, and the interference prevention notch 50 formed in the lid 3 prevents the connecting protrusion 12 provided on the main body 2 from contacting the lid 3. Therefore, the opening operation of the lid 3 can be performed smoothly.
[0083] As the lid 3 is opened toward the open position, the guided portion 52a of the acted portion 52 of the lid 3 slides and is guided by the locking portion 30 of the main body 2, and then the locked portion 52b engages with the locking portion 30 (see FIG. 15). Therefore, the lid 3 is locked to the main body 2 and held in a predetermined position. At this time, the lid 3 is opened, for example, by about 120 degrees relative to the main body 2.
[0084] In this way, the hot plate 1 is provided with a locking portion 30 that locks the lid body 3 at a position between the closed position and the open position, and when the lid body 3 is opened, it is temporarily held at an angle of, for example, approximately 120 degrees.
[0085] Therefore, the locking unit 30 locks the lid 3 while it is being opened, temporarily stopping the opening operation of the lid 3, so that even if the hand 90 holding the lid 3 or the movable leg 4 is released, the lid 3 will not open to the open position due to its own weight and will not accelerate toward the open position. This prevents the movable leg 4 from colliding with the placement surface 100 with a large impact due to acceleration, and prevents excessive load from being applied to the connecting portion between the lid 3 and the main body 2, improving safety during the opening operation of the lid 3 and preventing damage to the connecting portion between the lid 3 and the main body 2.
[0086] Furthermore, if the two movable legs 4 have not been rotated to the second rotation position when the cover body 3 is in the closed position, the two movable legs 4 may be rotated to the second rotation position when the cover body 3 is opened and temporarily held at an angle of approximately 120 degrees.
[0087] Next, in order to open the lid 3 to the open position, the locked state by the locking unit 30 is released (see Figure 16). The unlocking can be done by lifting the lid 3 upward while rotating it slightly toward the closed position.
[0088] When the cover 3 is rotated slightly toward the closed position, the locked portion 52b is disengaged from the locking portion 30, and the cover 3 is lifted upward, causing the fulcrum shaft 53 to move upward in the support hole 12a of the connecting projection 12. At this time, the acted-on portion 52 of the cover 3 is moved above the locking portion 30, and the cover 3 is placed in a state in which it can be further opened toward the open position.
[0089] Next, with the lid 3 lifted upward, the lid 3 is further opened toward the open position. As the lid 3 is further opened, the support portions 61 of the two movable legs 4 positioned in the second rotation position come into contact with the placement surface 100, and the lid 3 is held in the open position (see FIG. 17). Therefore, the lid 3 is held in the open position while being supported by the two support portions 61.
[0090] In this way, in the hot plate 1, when the main body 2 is placed on the placing surface 100, the movable legs 4 are rotated to the second rotation position and come into contact with the placing surface 100, thereby holding the lid 3 in the open position.
[0091] Therefore, when the lid body 3 is opened to the open position, the movable legs 4 come into contact with the placing surface 100 to hold the lid body 3 in place, so that the lid body 3 is held in the open position in a stable manner by the movable legs 4, ensuring sufficient safety during cooking.
[0092] The lid body 3 is held in an open position, opened 180 degrees relative to the main body 2, and the main body 2 is supported by the legs 13 while the lid body 3 is supported by the movable legs 4, making it possible to cook food using the first cooking plate 9 and the second cooking plate 35 in a stable position.
[0093] When cooking using hot plate 1, first cooking plate 9 and second cooking plate 35 are provided on hot plate 1, so cooking can be performed using both first cooking plate 9 and second cooking plate 35 simultaneously, improving convenience during cooking. However, cooking can also be performed using only first cooking plate 9 by operating selector switch 23 to set to the first heating mode, in which only first cooking plate 9 is heated.
[0094] In this way, with the hot plate 1, it is possible to cook using the first cooking plate 9 and the second cooking plate 35 simultaneously, or it is also possible to cook using only the first cooking plate 9, allowing you to select either one as needed, further improving convenience.
[0095] Hot plate 1 may be configured to be able to set a heating mode in which only second cooking plate 35 is heated.
[0096] Furthermore, in the hot plate 1, the height of the first standing wall portion 32 of the first cooking plate 9 is higher than the height of the second standing wall portion 55 of the second cooking plate 35. Therefore, it is preferable to use the first cooking plate 9 to cook foods that may be stirred with cooking tools such as a spatula or a turner, such as stir-fried vegetables or yakisoba, and it is preferable to use the second cooking plate 35 to cook foods that may be turned over with cooking tools such as a spatula or a turner, such as okonomiyaki or pancakes.
[0097] In this way, in the hot plate 1, the thickness of the lid 3 is thinner than the thickness of the main body 2, and the height of the first standing wall 32 is higher than the height of the second standing wall 55. This makes it possible to cook using both the first cooking plate 9 and the second cooking plate 35, which are provided with the first standing wall 32 and the second standing wall 55, respectively, which are different in height. Therefore, the food to be cooked using the first cooking plate 9 and the food to be cooked using the second cooking plate 35 can be selected according to the type, further improving convenience in cooking.
[0098] In particular, by using the first cooking plate 9 having the high first standing wall portion 32 to cook food such as stir-fried vegetables or fried noodles, the food is less likely to fly out from the first cooking plate 9, allowing the food to be cooked easily and safely. Also, by using the second cooking plate 35 having the low second standing wall portion 55 to cook food such as okonomiyaki or pancakes, the food is less likely to be turned over with cooking utensils that interfere with the second standing wall portion 55, allowing the food to be cooked easily and safely.
[0099] Furthermore, when the lid body 3 is opened to the open position, the vertical position of the first cooking surface portion 31 on the first cooking plate 9 and the vertical position of the second cooking surface portion 54 on the second cooking plate 35 are different positions, and the second cooking surface portion 54 is at a higher position than the first cooking surface portion 31.
[0100] In this manner, by positioning the first cooking surface portion 31 and the second cooking surface portion 54 at different heights when cooking, it becomes possible to select the first cooking plate 9 or the second cooking plate 35 depending on the type of food being cooked and the user's preferences, thereby further improving convenience in cooking.
[0101] When the cover 3 is held in the open position, the cover 3 is supported by the two movable legs 4 as described above.
[0102] At this time, as described above, when cooking food such as okonomiyaki using the second cooking plate 35 of the lid body 3, the food may be pressed down by the cooking utensil, and an external force may be applied from the cooking utensil to the movable leg 4 via the lid body 3.
[0103] In this way, even if an external force is applied to the movable leg 4 from the cooking utensil via the lid body 3 during cooking, the hot plate 1 is provided with a locking mechanism 64 that locks the movable leg 4 in the second rotation position relative to the lid body 3.
[0104] Therefore, since the movable leg 4 is locked to the lid body 3 by the locking mechanism 64, the movable leg 4 does not rotate toward the first rotation position even when an external force is applied, so that the lid body 3 can be held stably in the open position and will not tilt, thereby improving the safety of the cook when cooking.
[0105] Furthermore, since the hot plate 1 is provided with two movable legs 4 each locked by a locking mechanism 64, the user is reminded that the locking is performed twice and is therefore less likely to forget to lock the movable legs 4, which allows the user to have a high level of awareness in ensuring safety.
[0106] Furthermore, the hot plate 1 is provided with two movable legs 4, which are positioned apart from each other in a direction perpendicular to the axial direction of the fulcrum shaft 53 (left and right direction).
[0107] Therefore, the lid body 3 is held in the open position by two movable legs 4 positioned at a distance in a direction perpendicular to the axial direction of the fulcrum shaft 53. Therefore, even if one of the movable legs 4 is rotated only from the first rotation position to just before the second rotation position and is not locked, and an external force is applied to rotate one of the movable legs 4 from the second rotation position toward the first rotation position, the other movable leg 4 can securely hold the lid body 3 in the open position, thereby further improving the safety of the cook.
[0108] The closing operation of the lid 3 from the open position to the closed position is performed by closing the lid 3 on the main body 2. At this time, the slidable surface 38a of the protruding connecting portion 38 on the lid 3 and the acted-on portion 52 slide sequentially from the flat surface 30b to the curved surface 30c of the locking portion 30 on the main body 2 (see FIG. 18).
[0109] Therefore, the cover 3 can be smoothly moved from the open position to the closed position, and the cover 3 can be easily and quickly closed.
[0110] When the cover body 3 reaches the closed position and is closed against the main body 2, the operating protrusion 68 of the locking member 65 supported by the movable leg 4 can be operated and lifted to rotate the movable leg 4 from the second rotation position toward the first rotation position (see Figure 19).
[0111] When the operating protrusion 68 is operated and lifted, the slide portion 67 slides against the biasing force of the spring member 66, the insertion portion 67b is pulled out of the lock hole 40 of the lid body 3, and the movable leg 4 is unlocked from the lid body 3. In the state in which the movable leg 4 is unlocked from the lid body 3, the movable leg 4 is rotated about the rotation shaft 63 as a fulcrum, and the movable leg 4 is rotated from the second rotation position to the first rotation position and accommodated in the accommodation recess 39.
[0112] In this way, the hot plate 1 has a storage recess 39 formed in the lid 3, and the movable legs 4 are stored in the storage recess 39 in the first rotation position, so that the movable legs 4 do not protrude from the outer surface of the lid 3, and the hot plate 1 can be made smaller.
[0113] With the lid 3 closed on the main body 2, the hot plate 1 can be stored in a desired space such as a storage rack or cupboard.
[0114] Hot plate 1 can be stored, for example, in a horizontal position with main body 2 and lid 3 stacked vertically, and also in a vertical position with main body 2 and lid 3 stacked horizontally. In the horizontal position, it is suitable for storage in a space with limited vertical space, and in the vertical position, it is suitable for storage in a space with limited front-to-back or left-to-right space.
[0115] In hot plate 1, slide knob 26 protrudes outward from one second side surface 7b, and protrusion 28 protrudes outward from the other second side surface 7b. Therefore, when hot plate 1 is stored (placed) in the upright position with either second side surface 7b facing downward, slide knob 26 comes into contact with placement surface 100 when one second side surface 7b faces downward, and protrusion 28 comes into contact with placement surface 100 when the other second side surface 7b faces downward.
[0116] Therefore, when hot plate 1 is stored with either second side surface 7b facing downward, the presence of slide knob 26 or protrusion 28 makes hot plate 1 unstable, making it impossible to ensure a stable storage state, and the user can recognize that the storage state is improper. Therefore, when hot plate 1 is stored in the upright position, either first side surface 7a faces downward.
[0117] When either second side surface 7b faces downward, the opening and closing direction of main body 2 and lid 3 is the direction in which the axial direction of fulcrum shaft 53 is horizontal, and so there is a risk that main body 2 and lid 3 may unintentionally open due to the weight of main body 2 and lid 3 or vibrations. Therefore, by configuring slide knob 26 and protrusion 28 to protrude from second side surface 7b as described above, the user is made aware of an improper storage state, and unintentional opening of main body 2 and lid 3 during storage can be prevented.
[0118] On the other hand, in the vertically placed state, the user can stably store the hot plate 1 with either first side surface 7a facing downward. However, since the second wall portion 18 of the main body 2 and the second wall portion 43 of the lid 3 are provided with a pair of mounting ribs 24 and a pair of mounting ribs 47 that protrude slightly outward from the second outer surface 18a and the second outer surface 43a, respectively, it is desirable to store the hot plate 1 with the first side surface 7a on the side where the mounting ribs 24 and the mounting ribs 47 are provided facing downward (see FIG. 20).
[0119] By storing the hot plate 1 with the first side surface 7a on which the mounting ribs 24 and 47 are provided facing downward, the hot plate 1 is stored with the mounting ribs 24 and 47, which are each formed in a straight line, in line contact with the mounting surface 100, thereby ensuring that the hot plate 1 is stored in a more stable state.
[0120] Furthermore, in the hot plate 1, for example, the mounting ribs 24 and the mounting ribs 47 may be formed in a shape that allows them to make point contact with the mounting surface 100, and the hot plate 1 may be configured so that the mounting ribs 24 and the mounting ribs 47 are stored in a state in which they are in contact with the mounting surface 100 at four points.
[0121] Furthermore, when hot plate 1 is stored in the upright position, if wall surface 200 is present, either second side surface 7b may be stored facing wall surface 200, but in this case, slide knob 26 or protruding portion 28 is in a state where it can come into contact with wall surface 200, so second side surface 7b does not come into contact with wall surface 200. Therefore, even if hot plate 1 is stored immediately after cooking is finished and the temperature has not yet dropped sufficiently, the heat of hot plate 1 is unlikely to be conducted to wall surface 200, and wall surface 200 can be protected.
[0122] In particular, when the protrusion 28 comes into contact with the wall surface 200, the outer surface 28a of the protrusion 28 is formed in a curved shape, so that the wall surface 200 can be prevented from being scratched.
[0123] In the hot plate 1, the slide knob 26 may be formed in a rounded shape to prevent the wall surface 200 from being damaged when the slide knob 26 comes into contact with the wall surface 200.
[0124] <Summary> As described above, the hot plate 1 comprises a lid body 3 whose thickness is thinner than that of the main body 2, and at least one movable leg 4 that can be rotated relative to the lid body 3 between a first rotation position and a second rotation position. When the main body 2 is placed on the mounting surface 100, the movable leg 4 rotated to the second rotation position comes into contact with the mounting surface 100, thereby holding the lid body 3 in the open position.
[0125] Therefore, the lid body 3, which is thinner than the main body 2, is opened and closed relative to the main body 2, and when the lid body 3 is opened to the open position, the movable legs 4 come into contact with the placing surface 100 to hold the lid body 3 in place. This makes it easy to make the lid body 3 lightweight, and the lid body 3 is held in the open and closed position stably by the movable legs 4, ensuring high convenience while also ensuring sufficient safety during cooking.
[0126] In addition, the first cooking plate 9 has a first cooking surface portion 31 on which the food to be cooked is placed and a first standing wall portion 32 that covers the first cooking surface portion 31 from the outer periphery, and the second cooking plate 35 has a second cooking surface portion 54 on which the food to be cooked is placed and a second standing wall portion 55 that covers the second cooking surface portion 54 from the outer periphery, and when the lid body 3 is in the closed position, at least a part of the second cooking plate 35 or at least a part of the first cooking plate 9 is inserted inside the first standing wall portion 32 or the second standing wall portion 55.
[0127] Therefore, when the lid body 3 is in the closed position, the overall thickness of the first cooking plate 9 and the second cooking plate 35 becomes thinner, so that the hot plate 1 can be made thinner when the lid body 3 is closed, ensuring good storage properties of the hot plate 1 when not in use.
[0128] Furthermore, the inner circumference of the first standing wall portion 32 is larger than the outer circumference of the second standing wall portion 55, and at least a portion of the second standing wall portion 55 is inserted inside the first standing wall portion 32 when the cover body 3 is in the closed position.
[0129] Therefore, since the first cooking plate 9 is provided on the main body 2 which is thicker than the lid body 3, the height of the first standing wall portion 32 can be made sufficiently high, the insertion amount of the second standing wall portion 55 inside the first standing wall portion 32 can be increased, and the hot plate 1 can be made thinner.
[0130] In particular, it becomes possible to maximize the area of the first cooking surface portion 31 and the second cooking surface portion 54 relative to the volume of the hot plate 1, thereby improving the area efficiency of the first cooking surface portion 31 and the second cooking surface portion 54 while ensuring the compactness of the hot plate 1.
[0131] Furthermore, when the lid body 3 is in the closed position, the entire second standing wall portion 55 is inserted inside the first standing wall portion 32, thereby increasing the amount of insertion of the second cooking plate 35 into the first cooking plate 9, thereby making the hot plate 1 even thinner.
