Mode for Carrying Out the Invention

[0008] <Summary> A first cooking appliance according to an aspect of the embodiment includes a cooking container for cooking an object to be cooked, and a cooking lid for covering the cooking container. The cooking lid includes a lid body and a handle, and the handle is configured to be foldable. Thereby, it can be made thinner by folding the handle. The second cooking appliance according to another aspect of the embodiment is the first cooking appliance, wherein the handle is annular in plan view and has a groove portion on its top surface connecting the inner peripheral side and the outer peripheral side of the annulus. Thereby, it is possible to prevent the handle from being adsorbed to another plate-like member (for example, a cooking plate, a frying pan, etc.). The third cooking appliance according to another aspect of the embodiment is the first or second cooking appliance, wherein the handle is provided in a recessed portion of the lid body. Thereby, the height of the cooking lid can be reduced. The fourth cooking appliance according to another aspect of the embodiment is any one of the first to third cooking appliances, wherein the lid body has a dish-shaped lid portion and a flange portion provided at an opening-side end of the lid portion, and the cooking container has a dish-shaped plate portion and a peripheral edge portion that projects outward in a direction parallel to the flat portion of the plate portion from the opening-side end of the plate portion, and the flange portion has an overhanging portion that overhangs the inner peripheral side of the peripheral edge portion when the cooking lid is placed on the cooking container with the handle on the side opposite to the plate portion. Thereby, it is possible to restrict the cooking lid from moving in a direction parallel to the flat portion of the plate portion. The fifth cooking appliance according to another aspect of the embodiment is any one of the first to fourth cooking appliances, wherein when the cooking lid is placed on the cooking container with the handle located on the cooking container side, the cooking lid is supported by the handle with the lid body separated from the cooking container. Thereby, it is possible to easily take out the cooking lid.

[0009] The cooking apparatus according to one aspect of the embodiment is a cooking apparatus including a cooking appliance composed of a cooking container and a cooking lid, wherein the cooking appliance is any one of the first to fifth cooking appliances described above. Thereby, by folding the handle, the entire apparatus can be made thinner in the folding direction. The second cooking apparatus according to another aspect of the embodiment is the first cooking apparatus, and includes a heater for heating the cooking container and a temperature sensor for detecting the temperature of the cooking container, wherein the heater is annular with a part missing, and the temperature sensor is arranged at the central position of the annular part with a part missing. Thereby, it becomes easier for the temperature sensor to detect a high-temperature state, and quick responsiveness of the temperature sensor can be obtained. The third cooking device according to another aspect of the embodiment is the second cooking device, wherein the temperature sensor is supported so as to be movable closer to and farther from the cooking container and is biased toward the cooking container side. As a result, the temperature sensor can surely come into contact with the cooking container, and a highly reliable detection result can be obtained. The fourth cooking device according to another aspect of the embodiment is the second or third cooking device, wherein the cooking container has a plurality of ribs extending toward the heater side at intervals along the extending direction of the heater. Thereby, uneven heating by the heater can be suppressed.

[0010] <First Embodiment> Here, a cooking utensil including a cooking plate as an example of a cooking container and a cooking lid will be described, and a hot plate as an example of the cooking utensil will be described.

[0011] 1. Overall This will be described with reference to FIGS. 1 and 2. The hot plate X includes a first cooking unit A, a second cooking unit B, two or more cooking plates 7, and a cooking lid 8, and the first cooking unit A and the second cooking unit B can be overlapped with each other, and the cooking plate 7 and the cooking lid 8 can be accommodated between the first cooking unit A and the second cooking unit B. The first cooking unit A and the second cooking unit B here are rectangular, square, or similar shapes in plan view based on the use state, and as shown in FIG. 3(a), they are used in an unfolded and adjacent state. In FIG. 3, a first plate 71 and a second plate 73 (see FIG. 4) are arranged in the first cooking unit A, and a first plate 72 (see FIG. 4) and a cooking lid 8 are placed on the second cooking unit B. The first cooking unit A and the second cooking unit B are foldably coupled by a hinge portion 34 at an adjacent side and are configured to be foldable as shown in FIG. 1. The state of FIG. 1 is defined as an accommodation state, and the state of FIG. 3 is defined as an unfolded state or a use state. When folding, as shown in Fig. 3(b), the handle 81 places the cooking lid 8, which is located inside one side of the first cooking section A and the second cooking section (here it is the second cooking section B), that is, the cooking lid 8 turned inside out, on one side of the first cooking section A and the second cooking section B (here it is the second cooking section B), and rotates the other side of the first cooking section A and the second cooking section B (here it is the first cooking section) around the hinge portion 34. Hereinafter, each part will be described.

[0012] 2. Cooking section The first cooking section A and the second cooking section B have members with the same function, although their shapes are slightly different. When explaining the common parts, the first cooking section A and the second cooking section B are simply referred to as the "first and second cooking sections", and the configuration on the first cooking section A side is denoted by "A", and the configuration on the second cooking section B side is denoted by "B" for explanation. For example, the reference numeral of the housing of the first cooking section A is "3A", and the reference numeral of the housing of the second cooking section B is "3B". When there is no need to distinguish them, they are denoted as housings 3A, 3B. Also, when one of the configurations of the first cooking section A and the second cooking section B does not appear in the drawing, "A" and "B" are attached. That is, when "A" or "B" is attached to the reference numeral, even if it does not appear in the drawing, it is assumed to have that configuration.

[0013] As shown in Fig. 4, the first and second cooking sections A, B include heaters 1A, 1B for heating the cooking plate 7, operation levers 2A, 2B for turning on / off and setting the temperature of each heater 1A, 1B, and temperature adjustment units 4A, 4B (see Fig. 5(b)) for turning on / off and adjusting the temperature of the heaters 1A, 1B according to the operation of the operation levers 2A, 2B, which are provided in the housings 3A, 3B. In addition to the above configuration, the first and second cooking sections A, B may include, for example, first holding (supporting) means 51A, 51B for holding (supporting) the cooking plate 7, second holding means 52A, 52B for maintaining the accommodation state, and safety units 6A, 6B for preventing excessive temperature rise of the heaters 1A, 1B. Here, all of these are provided.

[0014] (a) Housing As shown in Fig. 4, the housings 3A and 3B have recesses 30A and 30B that are recessed from the opposing surfaces in the housed state. The housings 3A and 3B have a square, rectangular, or similar shape (here, a square shape) in plan view in the deployed state, and the recesses 30A and 30B also have a square, rectangular, or similar shape (here, a rectangular shape that is long in the direction parallel to the hinge portion 34) in plan view. In Fig. 4, the tips of the extension lines of the recesses 30A and 30B are shown as arrows to distinguish them from the extension lines of the bottom portions 31A and 31B. Heaters 1A and 1B are arranged at the bottom portions 31A and 31B of the recesses 30A and 30B of the housings 3A and 3B, and first safety units 61A and 61B are provided at the central positions of the heaters 1A and 1B. As shown in Fig. 3, hinge portions 35A and 35B are provided on one long side of the rectangular recesses 30A and 30B at the peripheral edge of the openings of the recesses 30A and 30B in the housings 3A and 3B, operation levers 2A and 2B are provided on one short side of the recesses 30A and 30B, first holding means 51A and 51B are provided on the short side of the recesses 30A and 30B, handle portions 32A and 32B are provided on the other long side of the recesses 30A and 30B, and second holding means 52A and 52B are provided on the handle portions 32A and 32B. As shown in Fig. 5(b), the housings 3A and 3B are provided with temperature adjustment units 4A and 4B and second safety units 62A and 62B between the recesses 30A and 30B and the outer wall portions 33A and 33B in the vicinity of the operation levers 2A and 2B. The housings 3A and 3B have hinge portions 35A and 35B. Here, the hinge portion 35A of the first cooking unit A is cylindrical, and the hinge portion 35B of the second cooking unit B has a fitting cylindrical portion 36 that fits inside the hinge portion 35A of the first cooking unit A, as shown in Fig. 5(a). Thereby, the housing 3A is connected to the housing 3B so as to be rotatable around the cylinder axis of the hinge portion 34.

[0015] (b) Heater As shown in Fig. 4, the heaters 1A and 1B are shaped such that the central portion of the short side of the rectangular shape corresponding to the recesses 30A and 30B is missing in a plan view of the unfolded state. The heaters 1A and 1B are each composed of a single sheathed heater. After their ends stand up from the recesses 30A and 30B, they extend in a rectangular shape within a plane parallel to the bottom portions 31A and 31B.

[0016] (c) Operating Lever and Temperature Adjustment Unit The operating levers 2A and 2B receive the operation of the user. Here, they are configured to be slidable in the short side direction of the housings 3A and 3B. When moving to one side to turn off the power supply and to the other side, the cooking plate 7 becomes hot. The temperature adjustment units 4A and 4B are each composed of a bimetal type temperature regulator that operates in conjunction with the operation of the operating levers 2A and 2B. The temperature regulator is electrically connected to the heaters 1A and 1B and adjusts the energization time of the heaters 1A and 1B according to the operation of the operating levers 2A and 2B.

[0017] (d) First Holding Means The first holding means 51A and 51B include engaged portions 53A and 53B (see Fig. 6) with which the engaging portions 74 of the cooking plate 7 engage, and engaging portions 54A and 54B (see Fig. 3) that engage with the cooking plate 7 in the engaged state. Here, the engaging portion 74 of the cooking plate 7 is composed of an extending portion that extends parallel to the bottom portions 31A and 31B of the recesses 30A and 30B as shown in Fig. 6(a). As shown in Fig. 6(b), the engaged portions 53A and 53B are composed of hole portions or recessed portions into which the extending portion (74) can be inserted and removed. During storage, with the cooking lid 8 stacked on one cooking plate 7 or with two cooking plates 7 stacked, they are stored in the recesses 30A and 30B. For this reason, the engaged portions 53A and 53B are long in the vertical direction. Thereby, the engaging portion 74 of the cooking plate 7 can be inserted into the engaged portions 53A and 53B from an oblique direction, and the cooking plate 7 and the cooking lid 8 (the cooking lid 8 does not have an engaging portion) can be easily stored in the recesses 30A and 30B. Note that the engagement relationship between the cooking plate 7 and the first holding means 51A and 51B may be reversed. The engaging parts 54A and 54B are provided with engaging pieces 55A and 55B that can slide out upward from the opening sides of the recesses 30A and 30B and project above the cooking plate 7 and the cooking lid 8 as shown in Fig. 5(b). The engaging pieces 55A and 55B have engaging portions 56A, 56B, 57A, and 57B at intervals in the vertical direction, and engage with the first plates 71 and 72 in a single state, the second plate 73, the first plate 71 and the second plate 73 in a stacked state, and the first plate 72 in a state where the first plate 72 and the cooking lid 8 are stacked. The engaging parts 54A and 54B here have a locking function with springs 58A and 58B that bias the engaging pieces 55A and 55B toward the cooking plate 7 side. The engaged parts 53A and 53B are two and are spaced in the short-side direction on one short-side of the recesses 30A and 30B as shown in Fig. 6(b). The two engaged parts 53A and 53B and the engaging parts 54A and 54B on the other short-side of the recesses 30A and 30B are at the three vertex positions of an isosceles triangle. Thereby, the cooking plate 7 can be held in a stable state.

[0018] (e) Second holding means The second holding means 52A and 52B includes a first engaging part 59A provided on the housing 3A of the first cooking part A and a second engaging part 59B provided on the housing 3B of the second cooking part B as shown in Fig. 3. Here, the first engaging part 59A is rotatable around a virtual axis parallel to the hinge part 34 and engages with the second engaging part 59B. Note that the engaging relationship between the first engaging part 59A and the second engaging part 59B may be reversed.

[0019] (f) Safety unit The safety units 6A and 6B include at least first safety units 61A and 61B that directly contact the cooking plate 7 and second safety units 62A and 62B arranged around the heaters 1A and 1B as shown in Fig. 5(b).

[0020] As shown in Fig. 4, the first safety units 61A and 61B are provided with temperature sensors 64A and 64B disposed at the central positions of the annular heaters 1A and 1B with a part of the short sides of the rectangular shape missing, that is, a shape with a part missing, in a plan view of the deployed state. This enables stable temperature control. Note that the centers of the heaters 1A and 1B correspond to the center of the cooking plate 7. As shown in Fig. 5, the first safety units 61A and 61B include temperature sensors 64A and 64B attached to the fixtures 63A and 63B, base bodies 65A and 65B that accommodate the fixtures 63A and 63B so as to be movable closer to or farther from the cooking plate 7, and biasing bodies 66A and 66B that bias the fixtures 63A and 63B in the base bodies 65A and 65B toward the cooking plate 7 side. Note that the base bodies 65A and 65B are fixed to the bottom portions 31A and 31B of the housings 3A and 3B. The temperature sensors 64A and 64B utilize bimetal and cut off power when the temperature exceeds a threshold temperature. The temperature sensors 64A and 64B are supported so as to protrude above the upper surfaces of the heaters 1A and 1B (the surfaces on which the cooking plate 7 is placed) when the cooking plate 7 is not placed. Thereby, when the cooking plate 7 is placed, the temperature sensors 64A and 64B surely come into contact with the cooking plate 7. Therefore, the temperature during cooking can be detected, and a rapid response can be made to an excessive temperature rise immediately after the start (so-called overshoot can be prevented).

[0021] The second safety units 62A and 62B utilize the bimetal of the temperature adjustment units 4A and 4B. The bimetal of the temperature adjustment units 4A and 4B detects the temperature between the bottom portions 31A and 31B of the housings 3A and 3B and the back surface of the cooking plate 7 as shown in Fig. 5(b). That is, the temperature of the ambient atmosphere around the heaters 1A and 1B is detected. Thereby, the unstable temperature state at the start of cooking can be quickly detected by the first safety units 61A and 61B, and the stable temperature state after a lapse of time from the start of cooking can be detected by the second safety units 62A and 62B. Note that the second safety units 62A and 62B detect the temperature of the ambient atmosphere around the heaters 1A and 1B through through-holes 68A and 68B provided in the peripheral walls of the recesses 30A and 30B of the housings 3A and 3B.

[0022] 3. Cooking Plate As shown in Fig. 4, the cooking plate 7 here is composed of flat first plates 71 and 72 and a second plate 73 having a plurality of hemispherical recesses 73a. Although the first plates 71 and 72 have the same configuration, for convenience, the first plate 72 is the one on which the cooking lid 8 is placed. The first plates 71 and 72 and the second plate 73 are rectangular in plan view, with engaging portions 74 provided at one short side portion and engaged portions 75 provided at the other short side portion. As shown in Fig. 6, there are two engaging portions 74 spaced apart in the short side direction, which engage (insert) with the engaged portions 53A and 53B of the first and second cooking portions A and B. As shown in Fig. 4, the engaged portion 75 is provided at the center in the short side direction of the other short side portion. The engaged portion 75 is formed by recessed portions on the upper surfaces of the peripheral edges 71b, 72b, and 73b of the first plates 71 and 72 and the second plate 73. As shown in Fig. 5(b), the engaging portions 54A and 54B of the first and second cooking portions A and B engage with the recessed portions. The first plates 71 and 72 have dish-shaped plate portions 71a and 72a and peripheral edges 71b and 72b that project outward in a direction parallel to the flat portions 71c and 72c of the plate portions 71a and 72a from the open side ends of the plate portions 71a and 72a. As shown in Fig. 5, the first plates 71 and 72 have a plurality of ribs 76 extending to the back side corresponding to the shapes of the heaters 1A and 1B on the back surface. The ribs 76 are provided so as to contact the outer peripheral surfaces of the heaters 1A and 1B, and a plurality of ribs 76 are provided at intervals along the extending direction of the heaters 1A and 1B as shown in Fig. 6(a). The ribs 76 have a length that is 0.5 to 3 times the dimension (width) in the direction orthogonal to the extending direction of the heaters 1A and 1B, and for the heaters 1A and 1B that are nearly rectangular, 2 to 4 ribs are provided for one of the short sides and the long sides. Thereby, the number of ribs 76 that block the radiant heat from the heaters 1A and 1B toward the first plates 71 and 72 (here, outward from the heaters 1A and 1B) is reduced, and the heating unevenness of the first plates 71 and 72 can be reduced. Note that the ribs 76 may be provided along the inside of the heaters 1A and 1B, or may be provided alternately on the inside and outside.

[0023] 4. Cooking lid As shown in FIGS. 4 and 7, the cooking lid 8 includes a lid body 80 and a handle 81. The handle 81 is attached to the lid body 80 by screwing a screw 82 inserted from the inside of the lid body 80 into a fixture 83 inside the handle 81. (1) Lid body The lid body 80 has a dish-shaped lid portion 80a corresponding to the planar shape of the cooking plate 7, and a flange portion 80b provided at the opening-side end of the lid portion 80a. As shown in FIG. 7, the lid portion 80a has a recessed portion 80d at the central portion of the top plate portion 80c. The handle 81 is provided in the recessed portion 80d. Thereby, the thickness of the cooking lid 8 can be reduced. The recessed portion 80d is recessed inward, that is, toward the cooking plate 7 side during use.

[0024] The flange portion 80b projects outward in the horizontal direction from the opening-side end of the lid portion 80a. The horizontal direction is a direction parallel to the bottom portions 31A, 31B of the housings 3A, 3B and the flat portion 72c of the first plate 72 (see FIG. 4) in the unfolded state or the housed state. As shown in FIG. 8, when the cooking lid 8 is placed on the first plate 72 with the handle 81 on the outer side (opposite side to the cooking plate 7), the flange portion 80b has at least an overhanging portion 80e that projects inside the inner peripheral side of the peripheral edge portion 72b of the first plate 72, and a flat portion 80f that extends flat in the horizontal direction from the outer peripheral edge of the overhanging portion 80e. The overhanging portion 80e is configured to be located inside the peripheral edge portion 72b of the first plate 72 as shown in FIG. 8(a). Thereby, the alignment of the cooking lid 8 with respect to the first plate 72 becomes easy. Also, the cooking lid 8 is positioned horizontally with respect to the first plate 72. The overhanging portion 80e is formed in an arc shape by bending. Thereby, the cooking lid 8 can be smoothly placed on the first plate 72. Also, the opening-side end portion of the cooking lid 8 can be reinforced. The flange portion 80b has, in addition to the protruding portion 80e and the flat portion 80f, a rounded curl portion 80g on the side of the top plate portion 80c from the horizontal outer peripheral edge of the flat portion 80f. Thereby, the safety when using or storing the cooking lid 8 can be improved.

[0025] (2) Handle The handle 81 is configured to be foldable. Specifically, the handle 81 is made of an elastic material such as silicone resin. As shown in FIGS. 7(b) and 7(c), the handle 81 has an attachment portion 84 attached to the lid body 80 via a fixture 83, a gripping portion 85 for gripping the handle 81 when holding it, and a connecting portion 86 that foldably connects the attachment portion 84 and the gripping portion 85. Here, the handle 81 has a "T" shape in a side view and a circular shape in a plan view when in use. This state is defined as the use state, and the folded state is defined as the folded state. The attachment portion 84 has a disk shape and has a stepped through hole 84a inside. The stepped portion of the through hole 84a has a smaller opening on the side of the lid body 80, and the stepped portion is clamped between the fixture 83 and the lid body 80. The gripping portion 85 has an annular shape in a plan view. Here, it has a circular ring shape. The dimension of the inner circumference of the gripping portion 85 is substantially equal to the dimension obtained by adding the thickness of the connecting portion 86 to the outer circumference of the attachment portion 84. The connecting portion 86 connects the gripping portion 85 to be bendable with respect to the attachment portion 84. Specifically, the connecting portion 86 is connected to be foldable outward with respect to the attachment portion 84 and foldable inward with respect to the gripping portion 85. When changing from the folded state to the use state, the gripping portion 85 is pulled out, and when changing from the use state to the folded state, the gripping portion 85 is pushed in. The handle 81 has, on the top surface of the gripping portion 85 (the surface opposite to the lid body 80), a groove portion 85a that connects the inner peripheral side and the outer peripheral side in the annular gripping portion 85 as shown in FIG. 4. Thereby, even when the top surface of the gripping portion 85 is adsorbed to the flat portion 72c of the first plate 72 due to moisture or the like when the cooking lid 8 is stored, air communicates through the groove portion 85a, so that the cooking lid 8 can be easily removed from the first plate 72. The fixture 83 has a size and shape that fits into the through-hole 84a of the attachment portion 84. The fixture 83 is made of a resin harder than the handle 81 and is configured to fit within the through-hole 84a. This prevents the fixture 83 from contacting the cooking plate 7.

[0026] 5. State (1) Storage state The first plate 71 and the second plate 73 are stacked and housed in the recess 30A of the housing 3A, and the cooking lid 8 is housed in the recess 30B of the housing 3B together with the first plate 72 with the handle 81 facing inward. In a state where the first cooking section A and the second cooking section B are overlapped, as shown in FIG. 2, since the handle 81 of the cooking lid 8 can be folded in the height direction, the thickness of the hot plate X can be reduced. When the first cooking section A is rotated around the hinge portion 34 and overlapped with the second cooking section B, even if the folding of the handle 81 is insufficient, since the handle 81 is made of silicone resin, it is possible to prevent the cooking lid 8 from being greatly deformed. The recessed portion 80d of the lid body 80 is configured to have a size that can accommodate the handle 81 when the folded handle 81 is viewed in plan. Thereby, the amount of protrusion of the folded handle 81 from the lid body 80 can be suppressed, and the thickness of the hot plate X in the storage state can be reduced.

[0027] (2) Use state The handle 81 and the recessed portion 80d are configured such that a person's finger can fit between the outer periphery of the handle 81 and the recessed portion 80d (peripheral wall portion). Thereby, it is possible to easily pull out the folded handle 81. In the storage state, as shown in FIG. 8(b), the flange portion 80b of the cooking lid 8 is configured to be separated from the peripheral edge portion 72b of the first plate 72. Specifically, when the folded cooking lid 8 is placed on the first plate 72, the cooking lid 8 is supported by the handle 81 such that the lid body 80 is separated from the first plate 72. Thereby, when taking out the cooking lid 8 in the storage state, it is possible to easily insert a finger between the first plate 72 and the cooking lid 8. As shown in FIG. 7(c), the handle 81 is configured to project from the top plate portion 80c of the lid body 80 in the folded state. Thus, when taking out the cooking lid 8 in the stored state, by pushing in one place of the flange portion 80b of the cooking lid 8, the distance between the first plate 72 and the cooking lid 8 increases on the side opposite to the portion pushed into the handle 81. This makes it easier for a finger to enter between the first plate 72 and the cooking lid 8.

[0028] <Second Embodiment> In the second embodiment, the description will focus on the parts different from the first embodiment. For the components having the same or corresponding configurations as those in the first embodiment, numbers obtained by adding "200" to the reference numerals in the first embodiment are mainly used. For example, the reference numeral for the cooking lid is "208", which is obtained by adding "200" to "8" of the cooking lid in the first embodiment. When there is no description of the configuration of the reference numerals shown in the drawings, the description is the same as that of the corresponding configuration in the first embodiment.

[0029] 1. Overall This will be described with reference to FIGS. 9 and 10. The hot plate X2 includes a first cooking section A2, a second cooking section B2, two or more cooking plates 207, and a cooking lid 208. The first cooking section A2 and the second cooking section B2 can be overlapped, and the cooking plates 207 and the cooking lid 208 can be accommodated between the first cooking section A2 and the second cooking section B2. Here, the first cooking section A2 and the second cooking section B2 are in a rectangular shape or a shape similar thereto with a short adjacent direction in a plan view based on the use state, and as shown in FIG. 10, they are unfolded and used. In FIG. 10, the first plate 271 and the second plate 273 are arranged in the first cooking section A2, and the first plate 272 and the cooking lid 208 are placed on the second cooking section B2. Note that FIG. 10(a) shows the unfolded state, and the handle 281 of the cooking lid 208 is on the lower surface side. The first cooking section A2 and the second cooking section B2 are foldably connected by a hinge portion 234 at an adjacent side. Also in the second embodiment, the state of FIG. 9 is defined as the stored state, and the state of FIG. 10 is defined as the unfolded state or the use state. Hereinafter, each part will be described.

[0030] 2. Cooking section The first cooking section A2 and the second cooking section B2 have members with the same functions, although their shapes and the like are slightly different, as in the first embodiment. When explaining the common parts, the first cooking section A2 and the second cooking section B2 are simply referred to as the "first and second cooking sections", and "A" is attached to the configuration on the side of the first cooking section A2, and "B" is attached to the configuration on the side of the second cooking section B2 for explanation. For example, the reference numeral of the housing of the first cooking section A2 is "203A", and the reference numeral of the housing of the second cooking section B2 is "203B". When there is no need to distinguish them, the housings are 203A and 203B. Also, when one of the configurations of the first cooking section A2 and the second cooking section B2 does not appear in the drawings, "A" and "B" are attached. That is, when "A" or "B" is attached to the reference numeral, even if it does not appear in the drawings, it is assumed to have that configuration.

[0031] As shown in FIGS. 11 and 12, the first and second cooking sections A2 and B2 include heaters 201A and 201B for heating cooking plates 207 (here, 271 and 273), operation levers 202A and 202B for turning on / off and setting the temperature of each heater 201A and 201B, and temperature adjustment units 204A and 204B (not shown) for turning on / off and adjusting the temperature of the heaters 201A and 201B according to the operations of the operation levers 202A and 202B, which are provided in the housings 203A and 203B. In addition to the above configuration, the first and second cooking sections A2 and B2 may include, for example, first holding (supporting) means 251A and 251B for holding (supporting) the cooking plate 207, second holding means 252A and 252B for holding the accommodation state, and safety units 206A and 206B for preventing excessive temperature rise of the heaters 1A and 1B. Here, all of these are provided.

[0032] (1) Housing As shown in FIGS. 11 and 12, the housings 203A and 203B have recesses 230A and 230B that are recessed in a rectangular shape from the opposing surfaces in the accommodation state, and heaters 201A and 201B and first safety units 261A and 261B are provided at the bottom portions of the recesses 230A and 230B. In the openings of the recesses 230A and 230B in the housings 203A and 203B, hinge portions 235A and 235B are provided on one long side of the recesses 230A and 230B, and handle portions 232A and 232B and second holding means 252A and 252B are provided on the other long side of the recesses 230A and 230B.

[0033] As shown in FIGS. 11 and 12, the housings 203A and 203B are composed of resin outer housings 233A and 233B that form the outer surfaces, metal inner housings 236A and 236B that form the recesses 230A and 230B, and resin upper housings 239A and 239B that cover the gaps at the upper ends of the outer housings 233A and 233B and the inner housings 236A and 236B. In the unfolded state, the housings 203A and 203B have a plurality of protruding ridges 231A and 231B that extend in the short side direction or the long side direction on the bottom outer surface (the surface facing the installation surface or the outer surface), as shown in FIG. 9. Thereby, the surface area can be increased and the heat dissipation characteristics can be improved. Further, the protruding ridges 231A and 231B can reinforce the bottom walls (front walls) of the outer housings 233A and 233B. The housings 203A and 203B have step portions 293A and 293B at one end or both ends in the longitudinal direction of the recesses 230A and 230B. Thereby, the space between the cooking plate 207 and the recesses 230A and 230B becomes smaller, and the heating efficiency can be increased. As shown in FIGS. 11 and 12, the housings 203A and 203B have recessed portions 294A and 294B adjacent to the engaging portions 254A and 254B of the first holding means 251A and 251B. The recessed portions 294A and 294B are sized such that a finger can fit under the cooking plate 207 in the mounted state, making it easy to remove the cooking plate 207 from the recesses 230A and 230B. Also, it becomes possible to release the engaging portions 254A and 254B and remove the cooking plate 207 with one hand.

[0034] As shown in Fig. 9, the handle parts 232A and 232B are provided on one side of the box shape formed by the housings 203A and 203B in the housed state. Here, they are provided on the side opposite to the hinge parts 235A and 235B that connect the housing 203A and the housing 203B. The handle parts 232A and 232B are rotatably supported by a rotation axis parallel to the hinge axis of the hinge parts 235A and 235B. The handle parts 232A and 232B have a "C" shape having a pair of extending parts 237A and 237B extending from the rotation axis side and handle parts 238A and 238B connecting the tips of the pair of extending parts 237A and 237B. The extending parts 237A and 237B are curved so as to follow the outer peripheral surfaces of the housings 203A and 203B when the handle parts 232A and 232B are tilted along the housings 203A and 203B. Thereby, it is possible to prevent the handle parts 232A and 232B from getting in the way when in use. The handle parts 232A and 232B are supported by the housings 203A and 203B so that the handle parts 238A and 238B come into contact with each other when the handle parts 232A and 332B are lifted during carrying. Thereby, the handle parts 232A and 232B can be easily lifted.

[0035] (2) Heater As shown in Figs. 11 and 12, the heaters 201A and 201B have a shape in which the central part of one short side of the rectangular shape corresponding to the recesses 230A and 230B is missing and the other end side is recessed toward the one short side. When viewed from above in the unfolded state, the heaters 201A and 201B have an "M" shape or a shape similar thereto. The heaters 201A and 201B are each constituted by a single sheathed heater. After the ends of the heaters are erected so as to pass through the through-holes of the recesses 230A and 230B, they extend in an M shape within a plane parallel to the bottom portions of the recesses 230A and 230B. As shown in FIG. 13, the heaters 201A and 201B include a pair of erected portions 211A and 211B erected from the bottom portion, a pair of short extension portions 212A and 212B extending outward in the short side direction from the tips of the erected portions 211A and 211B, a pair of long outer extension portions 213A and 213B extending in the longitudinal direction from the pair of short extension portions 212A and 212B, a pair of semicircular folding-back portions 214A and 214B folded back inward in the short side direction from the long outer extension portions 213A and 213B, a pair of long inner extension portions 215A and 215B extending in the longitudinal direction from the pair of folding-back portions 214A and 214B, and semicircular connecting portions 216A and 216B connecting the pair of long inner extension portions 215A and 215B. The heaters 201A and 201B are arranged such that the center in the short side direction between the pair of long outer extension portions 213A and 213B and the center in the longitudinal direction between the short extension portions 212A and 212B and the folding-back portions 214A and 214B are located at the center of the recesses 230A and 230B. As shown in FIG. 13, the interval in the short side direction between the long outer extension portions 213A and 213B and the long inner extension portions 215A and 215B adjacent to each other in the short side direction is in the range of 0.9 to 1.1 with respect to the interval in the short side direction between the pair of long inner extension portions 215A and 215B. Thereby, the cooking plate 207 can be heated evenly in the short side direction. In the longitudinal direction, the longitudinal interval L2 between the folding-back portions 214A and 214B and the connecting portions 216A and 216B is 1 / 2 or more with respect to the longitudinal interval L1 between the short extension portions 212A and 212B and the folding-back portions 214A and 214B. Specifically, it is in the range of 55 to 75%. Thereby, the cooking plate 207 can be heated evenly in the longitudinal direction. As shown in FIG. 13, the heaters 201A and 201B are supported at a plurality of locations by heater supports 217A and 217B. The upper surfaces of the heaters 201A and 201B are flat surfaces in order to ensure the contact area with the cooking plate 207.

[0036] (3) First holding means The first holding means 251A and 251B include engaged portions 253A and 253B with which the engaging portion 274 of the cooking plate 207 engages as shown in FIG. 12, and engaging portions 254A and 254B (see FIG. 3) that engage with the cooking plate 7 in the engaged state as shown in FIG. 10(a).

[0037] (3-1) Engaged Portion Here, the engaging portion 274 of the cooking plate 207 is constituted by an extending portion that extends parallel to the bottom portions of the recesses 230A and 230B as shown in FIG. 11, and the engaged portions 253A and 253B are constituted by hole portions into which the engaging portion 274 can be inserted and removed as shown in FIG. 12. Here, in order to stack and accommodate the first plate 271 and the second plate 273 as shown in FIG. 10(b), as shown in FIG. 14(b), it is constituted by two hole portions 295A and 295B provided vertically. Thereby, when using one cooking plate 207, by utilizing the bottom hole portions 295A and 295B, the vertical play of the cooking plate 207 is restricted. Further, the hole portions 295A and 295B are constituted by hole forming tools 291A and 291B made of a metal material having two recesses, and the hole forming tools 291A and 291B are attached to the upper housings 239A and 239B of the housings 203A and 203B by screws or the like (not shown). Thereby, the heat resistance of the hole forming tools 291A and 291B that come into contact with the engaging portion 274 is ensured. Also, by configuring the hole forming tools 291A and 291B from a metal material, the upper housings 239A and 239B can be configured from a resin material.

[0038] (3-2) Engaging Portion The engaging portions 254A and 254B have a locking function and include engaging portions 256A, 256B, 257A, and 257B provided at intervals in the vertical direction as shown in Fig. 14(c), engaging pieces 255A and 255B having stopper portions 250A and 250B, springs 258A and 258B that bias the engaging pieces 255A and 255B toward the cooking plate 207 side, and metal plates 260A and 260B provided on the lower surface sides of the engaging pieces 255A and 255B. Since the metal plates 260A and 260B are provided, heat resistance can be ensured even if the engaging pieces 255A and 255B are made of a resin material.

[0039] (4) Second holding means As shown in Figs. 11 and 12, the second holding means 252A and 252B are provided in the vicinity of the handle portions 232A and 232B. Specifically, the second holding means 252A and 252B are provided outside the rotation axis with respect to the handle portions 232A and 232B. Thereby, when holding and releasing, the handle portions 232A and 232B are less likely to get in the way, and the operability can be improved. Also, since they are held on both sides of the handle portions 232A and 232B, they can be held more firmly than when the second holding member is provided at one location. It includes a first engaging portion 259A (see Fig. 11) provided on the housing 203A of the first cooking unit A2 and a second engaging portion 259B (see Fig. 12) provided on the housing 203B of the second cooking unit B2. Here, the engaging piece that is the first engaging portion 259A is rotatably supported around a virtual axis parallel to the hinge portion 234 and the handle portions 232A and 232B, and engages with the engaging rod that is the second engaging portion 259B. That is, the second holding means 252A and 252B are buckle-type holding means. Note that the engagement relationship between the first engaging portion 259A and the second engaging portion 259B may be reversed.

[0040] (5) Safety unit The safety units 206A and 206B include at least first safety units 261A and 261B that come into direct contact with the cooking plate 207 and second safety units 262A and 262B arranged around the heaters 201A and 201B. As shown in FIG. 13 and the like, the first safety units 261A and 261B are provided at substantially the center in the short side direction between the pair of inner length extension parts 215A and 215B and at substantially the center in the longitudinal direction between the folding parts 214A and 214B and the connecting parts 216A and 216B in a plan view of the deployed state. Thereby, stable temperature control becomes possible. When viewed from above in the deployed state, the first safety units 261A and 261B are displaced from the center of the rectangular recesses 230A and 230B to the side opposite to the standing parts 211A and 211B. The side opposite to the standing parts 211A and 211B has a pair of inner length extension parts 215A and 215B, connecting parts 216A and 216B, and folding parts 214A and 214B, and tends to have an increased temperature, enabling temperature control at a location where the cooking plate 207 is likely to become hot.

[0041] As shown in FIG. 14, the first safety units 261A and 261B include fixtures 263A and 263B that are vertically movable with respect to the recesses 230A and 230B, temperature sensors 264A and 264B attached to the fixtures 263A and 263B, rod-shaped fixtures 266A and 266B that pass through the insertion holes of the flange parts 265A and 265B of the fixtures 263A and 263B and are fixed to the recesses 230A and 230B, and biasing bodies (spring bodies) 267A and 267B that are provided on the fixtures 266A and 266B and bias the flange parts 265A and 265B of the fixtures 263A and 263B toward the cooking plate 207 side. The biasing bodies 267A and 267B are arranged between the head parts of the fixtures 266A and 266B and the flange parts 265A and 265B of the fixtures 263A and 263B, and the end parts on the side opposite to the head parts of the fixtures 266A and 266B are fixed. As shown in FIG. 13(b), the fixtures 266 are provided at three or more locations. Here, there are three, and they are arranged at the vertex positions of an equilateral triangle when viewed from above in the deployed state. Thereby, the fixtures 263A and 263B can be supported in a well-balanced manner.

[0042] Similar to the first embodiment, the second safety units 262A and 262B utilize the bimetals of the temperature adjustment units 204A and 204B to detect the temperature of the ambient atmosphere around the cooking plate 207 through through-holes 268A and 268B provided in the peripheral walls of the recesses 230A and 230B of the housings 203A and 203B. As shown in FIG. 12, the through-holes 268A and 268B are provided in portions located on the inner sides of the recesses 230A and 230B in the stepped portions 293A and 293B. Thereby, the bimetal gets closer to the cooking plate 207 which is the heat source, the reaction speed of the bimetal increases, and the temperature of the cooking plate 207 can be stabilized early.

[0043] 3. Cooking Plate As shown in FIG. 10, here, the cooking plate 207 is a flat first plate 271, a first plate 272 having a ridge portion 272c, and a second plate 273 having a plurality of hemispherical recessed portions 273a. Similar to the first embodiment, the first plates 271 and 272 and the second plate 273 have an engaging portion 274 (see FIG. 11) and an engaged portion 275 (see FIGS. 11 and 14(c)). Similar to the first embodiment, the first plates 271 and 272 have plate portions 271a and 272a, peripheral edge portions 271b and 272b, and ribs 276. Similar to the first embodiment, the second plate 273 has a plate portion 273c, a plurality of recessed portions 273a provided in the plate portion 273c, a peripheral edge portion 273b, and ribs 276. The first plates 271 and 272 and the second plate 273 have flat contact portions 277 that contact the upper surfaces of the heaters 201A and 201B. Note that the ribs 276 are provided on the outer peripheral side of the contact portion 277. As shown in FIGS. 11, 12, and 14(a), the first plates 271 and 272 have contact portions 278 on the back surfaces of the plate portions 271a and 272a that come into contact with the temperature sensors 264A and 264B of the first safety units 261A and 261B. The contact portions 278 protrude downward from the plate portions 271a and 272a and are provided so as to push down the temperature sensors 264A and 264B downward. Thereby, the first plates 271 and 272 are surely in contact with the temperature sensors 264A and 264B.

[0044] <Others> (1) Configuration 1 The first plate 71 and the second plate 73 are overlapped and housed in the recess 30A of the housing 3A, and with the handle 81 on the inside, the cooking lid 8 is housed in the recess 30B of the housing 3B together with the first plate 72. In the state where the first cooking unit A and the second cooking unit B are folded, as shown in FIG. 2, the cooking lid 8 and the second plate 73 are located within the recesses 30A and 30B. Thereby, the cooking lid 8 and the second plate 73 do not interfere with each other. On the other hand, in Patent Document 1 described in the background art, since the flange portions of the plate 43 and the lid body 40 are sized to protrude from the main body in the state where they are set on the control-side main body and the non-control-side main body (hereinafter simply referred to as the "main body"), even when the plate 43 and the lid body 40 are housed in the main body and the main body is folded, the flange portions remain in a protruding state from the main body. For this reason, the plate 43 and the lid body 40 interfere with each other at the flange portions, and the flange portions may be damaged. In addition, if the flange portion of the plate 43 is damaged, there is also a risk of rusting due to peeling of the coating. Therefore, the above-described Configuration 1 solves the problem of damaging the flange portion in Patent Document 1. When paying attention to the problem of damaging the flange portion, the handle of the cooking lid 8 does not have to be foldable, and the configuration of the cooking lid 8, the cooking plate 7, and the safety units 6A and 6B are not particularly limited. The configuration described in Patent Document 1 is explained in the terms of that document.

[0045] (2) Configuration 2 The first plate 71 and the second plate 73 are stacked and accommodated in the recess 30A of the housing 3A. With the handle 81 facing inward, the cooking lid 8 is accommodated together with the first plate 72 in the recess 30B of the housing 3B. In the state where the first cooking section A is rotated around the hinge section 34 and overlapped with the second cooking section B, as shown in FIG. 2, the handle 81 of the cooking lid 8 abuts against the flat portion 72c of the first plate 72. Furthermore, the handle 81 is made of silicone resin. Thereby, the cooking lid 8 becomes difficult to slide with respect to the first plate 72, and it is possible to prevent the first plate 72 from being damaged. Also, since it abuts against the flat portion 72c of the handle 81, although the cooking lid 8 is only engaged by the engaging portion 54B of the first holding means 51B, its movement is restricted. In this way, the movement of the cooking lid 8 can be restricted with a simple structure. On the other hand, in Patent Document 1, only the flanges of the plate 43 and the lid body 40 are stacked and stored, and misalignment between the flanges can also occur. And when carrying the main body in a misaligned state, it becomes easy for an object to collide with the misaligned portion, and there is a risk of damage to the sliding portion between the plate 43 and the lid body 40, or rust due to peeling of the coating. Therefore, the above-described Configuration 2 solves the problem in Patent Document 1 that the plate and the lid body are likely to be misaligned during carrying. Incidentally, when paying attention to the problem of being likely to be misaligned, the handle of the cooking lid 8 does not have to be foldable, and the configuration of the cooking lid 8, the cooking plate 7, and the safety units 6A and 6B are not particularly limited. The configuration described in Patent Document 1 is explained in the terms of that document.

[0046] (3) Configuration 3 When the cooking lid 8 is accommodated together with the first plate 72 in the recess 30B of the housing 3B with the handle 81 facing inward, in a cooking utensil or a cooking apparatus where the handle 81 abuts against the first plate 72, the handle 81 is made of silicone resin. Thereby, the cooking lid 8 becomes difficult to slide with respect to the first plate 72, and it is possible to prevent the first plate 72 from being damaged. On the other hand, in Patent Document 1, the lid handle portion 41 is made of resin, and when the plate 43 and the lid handle portion 41 slide, there is a risk that the plate 43 may be scratched or rusted due to peeling of the coating. Therefore, the above-described Configuration 3 solves the problem in Patent Document 1 that the plate and the lid handle portion of the lid body are likely to be damaged by sliding. When paying attention to the problem of being easily damaged by sliding, the handle of the cooking lid 8 does not have to be foldable, and the configuration of the cooking lid 8, the cooking plate 7, and the configurations of the safety units 6A and 6B are not particularly limited. The configuration described in Patent Document 1 is explained in the terms of that document. Further, this problem can also be applied to a cooking appliance or a cooking device including a cooking container and a cooking lid.

[0047] (4) Configuration 4 The first and second cooking units A and B include heaters 1A and 1B having an annular shape or a shape close to an annular shape with a part missing, and temperature sensors 64A and 64B arranged at a central position of the annular shape or a shape close to an annular shape with a part missing and in contact with the cooking plate 7. Thereby, it is possible to prevent an excessive temperature (overshoot) due to the temperature rise after the start of heating. On the other hand, for example, in Patent Document 2 of Japanese Patent Application Laid-Open No. 2017-93727, only the second safety unit described in the embodiment is provided, and there is a possibility of overshooting after the start of heating. Therefore, the above-described Configuration 4 solves the problem in Patent Document 2 that there is a possibility of overshooting after the start of heating. When paying attention to the problem of overshoot, the folding structure of the cooking lid 8, the cooking plate 7, and the first and second cooking units A and B is not limited. Further, this problem can also be applied to a cooking device including a cooking appliance and a heater.

[0048] (5) Configuration 5 The first plates 71 and 72 have a plurality of ribs 76 extending toward the heaters 1A and 1B at intervals along the extending direction of the heaters 1A and 1B. Thereby, the number of ribs that block the radiant heat from the heaters 1A and 1B toward the first plates 71 and 72 is reduced, and the heating unevenness of the first plates 71 and 72 can be reduced. In contrast, in Patent Document 2 mentioned above, ribs are provided on both sides along the stretching direction of the heater, and the heating temperature at the portion where the radiant heat is blocked by the ribs is low, resulting in uneven heating. Therefore, the above-described Configuration 5 solves the problem of significant uneven heating in Patent Document 2. When focusing on uneven heating, the folding structures of the cooking lid 8, the cooking plate 7, and the first and second cooking parts A and B are not limited. Further, this problem can also be applied to a cooking apparatus including a cooking utensil and a heater.

[0049] As described above, the first and second embodiments have been explained, but the present invention is not limited to these embodiments. For example, the following modifications may be possible. Also, combinations of an embodiment, each modification, and each pair of modifications may be possible. In addition, examples not described in the embodiments and modifications, and design changes within the scope not departing from the gist are also included in the present invention.

[0050] <Modification> 1. Cooking Utensil The cooking utensil may be any cooking utensil including a cooking container for cooking an object to be cooked and a cooking lid with a handle for covering the cooking container. For example, it may be a cooking pot with a lid, a frying pan, a kettle, or the like. 2. Cooking Apparatus The cooking apparatus only needs to be able to heat the cooking container for cooking. For example, in addition to a hot plate, it may be a pot, a pressure vessel (autoclave) with a heater, or the like. Also, the hot plate may be a double-sided type or a single-sided type.

[0051] 3. Hot Plate In the embodiment, the first cooking part A and the second cooking part B were rotatably connected using the hinge part 34, but a structure not using the hinge part may also be used. As such a structure, for example, the independent first cooking part A and the second cooking part B may be overlapped, and a holding part or a holding body such as a buckle or a belt may be used to hold the overlapped state.

[0052] 4. Cooking Part The heaters 1A and 1B of the first and second cooking units A and B use a single sheath heater, but a plurality of sheath heaters may be used. When providing the first safety units 61A and 61B, in a plan view, they may be provided at positions that are the centroids of the figures formed by the peripheries of the plurality of sheath heaters. The heaters 1A and 1B of the first and second cooking units A and B have a rectangular shape (annular shape) with a part of the short side missing, but may have a polygonal annular shape such as a triangular shape with a part missing, an elliptical shape with a part missing, a circular shape, an oval shape, etc. The folded-back portions 214A and 214B and the connecting portions 216A and 216B of the heaters 201A and 201B are semi-circular, but may be linear, semi-elliptical, or semi-oval. Also, the short extension portions 212A and 212B, the outer long extension portions 213A and 213B, and the inner long extension portions 215A and 215B are linear, but may be curved. The handle portions 232A and 232B are provided on the surface facing the surface where the hinge portions 235A and 235B are provided in the housed state, but may be provided on other adjacent surfaces. For example, when providing the handle portion on the surface where the operation levers 202A and 202B are provided, it can be implemented by changing the positions of the operation levers 202A and 202B or ensuring non-interference, or the operation levers 202A and 202B may be provided on the surface facing the hinge portions 235A and 235B or the surface on the side where the first holding means 251A and 251B are provided. The second safety units 262A and 262B detect the temperature of the ambient atmosphere around the cooking plate 207 through the through holes 268A and 268B of the housings 203A and 203B. However, for example, they may be brought into contact with the portions located inside the recesses 230A and 230B in the step portions 293A and 293B to measure the temperature of the heat transmitted from the recesses 230A and 230B. Also in this case, by providing them on the step portions 293A and 293B of the cooking plate 207, the bimetal can be closer to the cooking plate 207, and the reaction speed of the bimetal can be increased. Incidentally, the second safety units 262A and 262B may be fixed to the recesses 230A and 230B with screws using the through holes 268A and 268B of the recesses 230A and 230B.

[0053] 5. Cooking lid (1) Lid body The lid body 80 was rectangular in plan view. However, when the hot plate and / or cooking plate is circular, elliptical, etc., it may be circular or elliptical according to them. The lid body 80 had a recessed portion 80d. However, when not paying attention to the thickness (height) of the cooking lid 8, it may not have a recessed portion, or conversely, a protruding portion may be provided. The recessed portion 80d was the same shape as the handle 81 in plan view. However, as long as it does not interfere with the folded handle 81, its shape may be different from the handle. However, considering the ease of pulling out the gripping portion 85 of the folded handle 81, it is preferable that a space for a finger to enter is formed between the folded gripping portion 85 and the recessed portion 80d. (2) Handle The handle 81 is circular in plan view. However, if it can be folded, it may have other shapes. However, considering the durability of repeated use of folding and pulling out, a circular shape is preferable.
