Description

[Technical Field]

[0001] The present invention relates to a cooking device, and more particularly to a pressure cooking device that applies pressure and heat to ingredients in an inner pot. [Background technology]

[0002] In a conventional heating cooker that heats ingredients in the inner pot and is equipped with a cooker body that houses an inner pot and an opening / closing lid that engages with the cooker body to cover the inner pot so that it can be opened and closed freely, a cooker is known that is equipped with a flat cable that connects electrical components on the cooker body side to electrical components on the opening / closing lid side, and a guide section on the inner surface of the opening / closing lid that aligns the flat cable along the flat cable and stabilizes the bent shape when it bends, and a position control section that is separate from the guide section and has a slit cut out from the side edge at the tip of the flat cable to control the flat surface of the flat cable so that it is parallel to the inner surface of the opening / closing lid (Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Patent No. 6291453 Summary of the Invention [Problem to be solved by the invention]

[0004] However, in the above-mentioned cooking device, the slit opens toward one side of the flat cable in the cable width direction, so when excess length is generated in the flat cable as the opening and closing lid is opened and closed, there is a risk that the flat cable will shift widthwise, i.e., shift sideways, and come out of the slit, causing it to bend and break.

[0005] Therefore, the present invention solves the problems of the prior art as described above, and the object of the present invention is to provide a pressure cooking appliance that prevents breakage of the cable due to bending of the excess length that occurs when the opening and closing lid is opened and closed. [Means for solving the problem]

[0006] The invention of claim 1 is a pressure-heating cooker comprising a cooker body incorporating a pressure-heating control unit, an opening / closing lid equipped with a display and operation control unit and rotatably opening and closing via a hinge unit at one end of the cooker body, and a cable connecting the pressure-heating control unit of the cooker body and the display and operation control unit of the opening / closing lid via the hinge unit, wherein the opening / closing lid is equipped with a pair of left and right cable width direction regulating units that stand upright from the inner surface of the opening / closing lid and regulate the movement of the cable in the cable width direction from both the left and right sides, thereby solving the above-mentioned problem.

[0007] The invention of claim 2 solves the above-mentioned problem by, in addition to the configuration of the invention of claim 1, having a cable slip-off prevention part in which the opening and closing cover is cantilevered horizontally from one of the pair of left and right cable width direction regulating parts to regulate movement of the cable in the thickness direction.

[0008] The invention of claim 3 further solves the above-mentioned problem by providing, in addition to the configuration of the invention of claim 1 or claim 2, a cable separation section in which the opening / closing cover is formed in a raised state from the inner surface of the opening / closing cover in the region between the pair of left and right cable width direction regulating sections, thereby freeing the cable in a non-contact state with the inner surface of the opening / closing cover.

[0009] The invention of claim 4 further solves the above-mentioned problem by providing, in addition to the configuration of the invention of claim 1 or claim 2, the opening / closing cover with a cable base portion, located near the pair of left and right cable width direction regulating portions and opposite the hinge portion, which separates the cable from the inner surface of the opening / closing cover in a non-contact state, and a cable fixing portion which fixes the cable to the cable base portion.

[0010] The invention of claim 5 further solves the above-mentioned problem by, in addition to the configuration of the invention of claim 1 or claim 2, having a pressure adjustment section in the internal space of the lid, and the cable width direction regulating section being positioned facing the internal space of the lid at a position between the pressure adjustment section and the hinge section. [Effects of the Invention]

[0011] According to the pressure-heating cooker of the invention of claim 1 of the present invention, the pressure-heating cooker comprises a cooker main body incorporating a pressure-heating control unit, an open / close lid equipped with a display and operation control unit and rotatably opening and closing via a hinge unit at one end of the cooker main body, and a cable connecting the pressure-heating control unit of the cooker main body and the display and operation control unit of the open / close lid via the hinge unit, wherein the open / close lid is equipped with a pair of left and right cable width direction regulating units that stand upright from the inner surface of the open / close lid and regulate the movement of the cable in the cable width direction from both the left and right sides, so that even if excess length occurs in the cable, the cable width direction arrangement is maintained in the area between the pair of left and right cable width direction regulating units, and the excess length is absorbed by the cable bending in a gentle curve as it moves in the cable thickness direction, thereby preventing the cable from breaking due to bending when excess length occurs when the open / close lid is opened or closed.

[0012] According to the pressure cooking cooker of the invention of claim 2 of the present invention, in addition to the effects achieved by the invention of claim 1, the opening and closing lid is equipped with a cable fall-off prevention part that is horizontally mounted in a cantilevered manner from one of the pair of left and right cable width direction regulating parts and regulates movement of the cable in the thickness direction.As a result, when the cable moves in the cable thickness direction, it abuts against the cable fall-off prevention part and remains within the cable holding area formed by the pair of left and right cable width direction regulating parts and the cable fall-off prevention part, so that excess cable length generated when the opening and closing lid is opened and closed can be prevented from escaping from the cable holding area and bending, thereby preventing breakage of the cable.

[0013] According to the pressure cooking cooker of the invention of claim 3, in addition to the effects of the invention of claim 1 or claim 2, the opening / closing lid is provided with a cable separation section that is formed in a state where it is raised from the inner surface of the opening / closing lid in the area between a pair of left and right cable width direction regulating sections, and keeps the cable free to be in a non-contact state with the inner surface of the opening / closing lid.This means that the cable is always held in a position separated from the inner surface of the opening / closing lid, preventing damage to the cable caused by contact with the inner surface of the opening / closing lid when the opening / closing lid is opened or closed, and preventing deterioration due to heat conduction from the opening / closing lid, and enabling the cable to flexibly deform in the cable thickness direction within the cable holding area.

[0014] According to the pressure cooking cooker of the invention of claim 4, in addition to the effects of the invention of claim 1 or claim 2, the opening and closing lid is provided with a cable base portion, located near the pair of left and right cable width direction regulating portions and opposite the hinge portion, which separates the cable from the inner surface of the opening and closing lid in a non-contact state, and a cable fixing portion which fixes the cable to this cable base portion.As a result, the range in which the cable bends is limited to the area between the cable fixing portion and the hinge portion, and therefore, when excess length is generated in the cable as a result of opening and closing the opening and closing lid, it is possible to more reliably prevent the cable from breaking due to bending near the electrical connection portion.

[0015] According to the pressure cooking cooker of the invention of claim 5, in addition to the effects achieved by the invention of claim 1 or claim 2, the opening / closing lid is provided with a pressure adjustment unit in the internal space of the lid, and the cable width direction regulating unit is arranged facing the internal space of the lid at a position between the pressure adjustment unit and the hinge unit in the internal space of the lid.Therefore, the cable width direction regulating unit regulates the movement of the cable in the cable width direction within a predetermined range at the position between the pressure adjustment unit and the hinge unit where the amount of movement of the cable due to excess length generated by opening and closing the opening / closing lid can be greatest, so that it is possible to even more reliably prevent breakage of the cable caused by excessive movement in the width direction and bending of the cable that has been bent by opening and closing the opening / closing lid.

[0023] <Configuration of pressure cooker> First, the configuration of a pressure cooking device 100 according to this embodiment will be described. As shown in Figures 1 and 2, the pressure cooking device 100 of this embodiment is a pressure rice cooker, and includes a cooking device main body 110, an opening / closing lid 120 that is rotatably engaged with the cooking device main body 110 at a hinge portion 140, a pressure adjustment portion 130 provided inside the opening / closing lid 120, and a flexible flat cable 150 that electrically connects the cooking device main body 110 and the opening / closing lid 120.

[0024] The cooking appliance body 110 includes a side cover 111, a shoulder member 112 arranged on the side cover 111, a protective frame 113 formed in a hemispherical shape at the bottom center of the shoulder member 112, an inner pot 114 arranged within the protective frame 113, an induction heating coil 115 for heating the inner pot 114, a pressure and heating control unit 116 consisting of a board on which various electronic components are mounted and for controlling the operation of the induction heating coil 115, a cord reel 117 and a power plug 118 for supplying power to the pressure and heating control unit 116, etc.

[0025] The opening / closing lid 120 includes a lid molded body 121 that constitutes the main part of the opening / closing lid 120, a switch sheet 122 that is tightly fixed to the surface of the lid molded body 121, a lid opening lever 123 that is operated to place the opening / closing lid 120 in an open state, a liquid crystal display unit 124 that is arranged visible inside the lid molded body 121, an indicator lamp 125 that displays the control status, etc., and a display operation control unit 126 that is composed of a board on which various electronic components are mounted and controls the input of cooking instructions, displays the operation content on the liquid crystal display unit 124, and displays the control status, etc. by lighting the indicator lamp 125.

[0026] As shown in FIGS. 1 to 5, the lid molded body 121 constitutes the main part of the opening / closing lid 120, forms the lid internal space IS, and is integrally molded from polypropylene.

[0027] As shown in Figures 3 to 5, the lid molded body 121 includes a pair of left and right cable width direction regulating sections 121a that are formed as tapered plates and arranged opposite each other, and are molded integrally with the lid molded body 121 from the inner surface of the lid molded body 121 toward the lid internal space IS, and that regulate the movement of the flexible flat cable 150 in the cable width direction from both the left and right sides; a thin plate-like cable slippage prevention section 121b that is arranged horizontally in a cantilever state from the tip end of one cable width direction regulating section 121a toward the tip end of the other cable width direction regulating section 121a; and a cable separation section 121c that is formed in a state raised from the inner surface of the open-close lid 120 in the region between the pair of left and right cable width direction regulating sections 121a, and that separates the flexible flat cable 150 from the inner surface of the lid molded body 121 to keep it out of contact.

[0028] As shown in Figures 5, 6A and 6B, the lid molded body 121 has a cable holding area CA that is surrounded by the above-mentioned pair of left and right cable width direction regulating portions 121a, cable fall-off prevention portion 121b and cable separation portion 121c.

[0029] The pair of left and right cable width direction regulating portions 121a, the cable fall-off prevention portion 121b, and the cable separation portion 121c that form the cable holding area CA are positioned between the pressure adjustment portion 130 and the hinge portion 140 when the opening / closing lid 120 is attached to the cooking appliance body 110 via the hinge portion 140, as shown in Figures 2 and 4, etc.

[0030] As shown in Figures 4 and 5, the lid molded body 121 is provided with a cable base portion 121d that is molded integrally with the lid molded body 121 from the inner lid surface of the lid molded body 121 toward the lid internal space IS and separates the flexible flat cable 150 from the inner lid surface of the lid molded body 121 in a non-contact state against the inner lid surface of the lid molded body 121, a plate-shaped cable fixing portion 121e that is formed integrally with this cable base portion and fixes the flexible flat cable 150 to the cable base portion 121d at the width-direction bent portion 151a of the flexible flat cable 150, and a cable engagement claw 121f that is formed at the tip portion of this cable fixing portion 121e and protrudes toward the inner lid surface of the lid molded body 121 and engages with the bent corner portion 151b of the width-direction bent portion 151a of the flexible flat cable 150.

[0031] As shown in Figure 2, etc., when the opening / closing lid 120 is attached to the cooking appliance body 110, the cable base portion 121d, the cable fixing portion 121e, and the cable engagement claw 121f are positioned near the cable holding area CA and on the opposite side of the hinge portion 140 from the cable holding area CA.

[0032] As shown in Figures 1 and 2, the switch sheet 122 has an operation section 122a printed on it that allows the user of the pressure cooking cooker 100 to input instructions for cooking, reservation, cancellation, etc., and the areas corresponding to the liquid crystal display section 124 and indicator lamp 125 arranged on the opening / closing lid 120 are transparent so that these can be seen, and the switch sheet 122 is configured to be tightly fixed to the surface of the lid molded body 121.

[0033] The lid-opening lever 123 is configured so that when pressed by the user of the pressure cooking cooker 100, the opening and closing lid 120 is placed in an open state with the hinge portion 140 located at one side end (more specifically, the rear end) of the cooker body 110 as the rotation center.

[0034] The liquid crystal display unit 124 is positioned in a position that is visible through the transparent portion of the switch sheet 122 of the lid molded body 121, and is controlled by the display operation control unit 126 to display the instructions input from the operation unit 122a and the status of cooking operation, etc.

[0035] The pressure adjustment unit 130 is arranged in the lid internal space IS formed by the lid molded body 121 inside the opening / closing lid 120, and when cooking using the pressure cooking device 100, it releases high-pressure steam from the inside through the steam port 131 so that the pressure inside the inner pot 114 becomes a predetermined value.

[0036] As shown in Figures 6A and 6B, the hinge section 140 is composed of a hinge shaft 141 that is arranged near the rear end of the pressure cooking appliance 100 and serves as the center of rotation when the opening and closing lid 120 is opened and closed, a hinge spring 142 that is arranged coaxially with the hinge shaft 141 and urges the opening and closing lid 120 in the opening direction, a damper (not shown) that reduces the opening and closing speed of the opening and closing lid 120, and a hinge cover 143 that covers the hinge shaft 141, hinge spring 142 and damper from the back side of the pressure cooking appliance 100.

[0037] As shown in Figures 2 and 3, the flexible flat cable 150 as a cable is composed of a cable main body 151 electrically connected to the display operation control unit 126 of the opening / closing lid 120, and a main body side connector 152 provided at one end of this cable main body 151 and electrically connected to the pressure heating control unit 116 of the cooking appliance main body 110.

[0038] One end of the cable main body 151 is electrically connected to the display operation control unit 126 of the opening / closing lid 120, and extends through the lid internal space IS formed by the lid molded body 121 of the opening / closing lid 120, the gap inside the hinge cover 143 of the hinge part 140 between the hinge cover 143 and the hinge shaft 141, and the inside of the back surface of the side cover 111 of the cooking appliance main body 110 to the pressure heating control unit 116 of the cooking appliance main body 110, and is electrically connected to the pressure heating control unit 116 by the main body side connector 152.

[0039] As shown in Figures 3 to 6B, the cable main body 151 is arranged to pass through the cable holding area CA formed by a pair of left and right cable width direction regulating portions 121a, a cable fall-off prevention portion 121b, and a cable separation portion 121c of the lid molded body 121.

[0040] As shown in Figures 3 and 4, the cable main body 151 has a widthwise bent portion 151a in its middle portion, and further has a bent corner portion 151b formed inside this widthwise bent portion 151a. A cable engaging claw 121f provided on the cable fixing portion 121e engages with this bent corner portion 151b, thereby fixing the cable main body 151 to the cable base portion 121d.

[0041] <Flexible flat cable operation when opening and closing the cover> Next, the behavior of the flexible flat cable 150 when the opening / closing lid 120 of the pressure cooking device 100 is opened or closed will be described.

[0042] As described above, one end of the cable main body 151 of the flexible flat cable 150 is connected to the display operation control unit 126 of the opening / closing lid 120, and the cable main body 151 is fixed to the cable base portion 121d at its widthwise bending portion 151a by the cable fixing portion 121e within the internal space IS of the opening / closing lid 120, and is held within the cable holding area CA formed by a pair of left and right cable widthwise regulating portions 121a, the cable fall-off prevention portion 121b and the cable separation portion 121c, allowing movement in the cable thickness direction, and is arranged to extend to the pressure heating control unit 116 via the gap between the hinge cover 143 and the hinge shaft 141 and the inside of the back surface of the side cover 111 of the cooking appliance body 110.

[0043] The length of the path along which the cable main body 151 of the flexible flat cable 150 extends changes depending on the opening and closing operation of the opening and closing cover 120, so that excess length may occur depending on the state of the opening and closing cover 120.

[0044] That is, when the opening / closing cover 120 is in the closed state, as shown in FIG. 6A, the cable fall-off prevention portion 121b and the hinge cover tip portion 143a are positioned apart, forming a space with a high degree of freedom in the position that the cable main body 151 extending between them can take.

[0045] Furthermore, when the opening / closing cover 120 is in the closed state, the length of the path along which the cable main body 151 can extend is long, so the excess length is relatively short, and the cable main body 151 bends in a gentle curve from the hinge cover tip 143a to the cable fixing portion 121e, and is positioned to pass through the cable holding area CA.

[0046] In this case, the cable main body 151 is disposed in the immediate vicinity of the cable separation section 121c, and extends to a position separated from the inner surface of the opening / closing cover 120.

[0047] In contrast, when the opening / closing cover 120 is in the open state, as shown in Figure 6B, the cable fall prevention part 121b and the hinge cover tip part 143a are positioned relatively close to each other, and the cable main body 151 arranged between them is clamped and fixed in a bent state in the narrow space between the cable fall prevention part 121b and the hinge cover tip part 143a.

[0048] At this time, since the cable main body 151 is always fixed to the cable base portion 121d by the cable fixing portion 121e at its widthwise bending portion 151a, an excess length of the cable main body 151 occurs between the cable fixing portion 121e and the cable fall-off prevention portion 121b.

[0049] Therefore, when a user presses down on the opening lever 123 of the opening / closing lid 120 of the pressure cooking cooker 100 in the closed state shown in Figure 6A, the elastic force of the hinge spring 142 of the hinge section 140 causes the entire opening / closing lid 120 to rotate around the hinge axis 141, resulting in the open state shown in Figure 6B, and in this process the cable main body 151 moves significantly in the cable thickness direction within the cable holding area CA.

[0050] Conversely, when a user rotates the opening / closing lid 120 of the pressure cooking cooker 100 from the open lid state shown in Figure 6B to the closed lid state shown in Figure 6A, the cable main body 151 moves significantly in the cable thickness direction within the cable holding area CA.

[0051] During either operation, the flexible flat cable 150 maintains its arrangement in the cable width direction within the cable holding area CA between the pair of left and right cable width direction restricting portions 121a, and is allowed to move in the cable thickness direction.

[0052] Furthermore, by providing a cable fall prevention part 121b that is horizontally arranged in a cantilever state from one cable width direction regulating part 121a to the other cable width direction regulating part 121a, even when the cable main body 151 moves significantly in the cable thickness direction, the cable main body 151 abuts against the cable fall prevention part 121b, and therefore remains within the cable holding area CA without falling off from the cable holding area CA.

[0053] Furthermore, the cable base portion 121d and the cable fixing portion 121e are arranged near the pair of left and right cable width direction regulating portions 121a on the opposite side of the hinge portion 140, and by fixing the flexible flat cable 150 near the cable width direction regulating portion 121a, the range in which bending occurs due to the excess length of the cable main body 151 is limited to the area between the cable fixing portion 121e and the hinge portion 140.

[0054] Here, when the pressure adjustment unit 130 is arranged within the lid internal space IS, the dimensions of the lid internal space IS are set large in the vicinity of the pressure adjustment unit 130. Therefore, if there are no restrictions on the arrangement of the cable main body 151, the deflection caused by the excess length of the cable main body 151 that occurs when the opening and closing lid 120 is opened and closed may be greatest in the vicinity of the pressure adjustment unit 130.

[0055] In contrast to this, in this embodiment, when the opening / closing lid 120 is assembled to the cooking appliance body 110, the cable width direction regulating portion 121a is positioned facing the lid internal space IS at a position between the pressure adjusting portion 130 and the hinge portion 140 in the lid internal space IS, and therefore, at the position between the pressure adjusting portion 130 and the hinge portion 140, the cable width direction regulating portion 121a regulates the movement of the cable main body 151 in the cable width direction within a predetermined range.

[0056] As described above, according to the pressure cooking cooker 100 of this embodiment, the opening / closing lid 120 is provided with a pair of left and right cable width direction regulating parts 121a that are arranged opposite each other and regulate the movement of the cable main body 151 in the cable width direction from both the left and right sides, while allowing and holding movement in the cable thickness direction. Therefore, even if excess length occurs in the cable main body 151, the cable width direction arrangement is maintained in the area between the pair of left and right cable width direction regulating parts 121a, and the excess length is absorbed by bending in a gentle curve while moving in the cable thickness direction, thereby preventing breakage of the cable main body 151 due to bending when the opening / closing lid 120 is opened or closed.

[0057] Furthermore, since the opening / closing lid 120 is provided with a cable fall prevention part 121b that is arranged in a cantilever state from one cable width direction regulating part 121a to the other cable width direction regulating part, when the cable main body 151 moves in the cable thickness direction, it abuts against the cable fall prevention part 121b and remains within the cable holding area CA formed by the pair of left and right cable width direction regulating parts 121a and the cable fall prevention part 121b, so that the cable main body 151 that has excess length due to the opening / closing operation of the opening / closing lid 120 can be prevented from breaking due to detaching from the cable holding area CA and bending.

[0058] Furthermore, the opening / closing lid 120 is formed in a state where it is raised from the inner surface of the opening / closing lid in the area between the pair of left and right cable width direction regulating portions 121a, and is equipped with a cable separation portion 121c that frees the flexible flat cable 150 in a non-contact state with the inner surface of the opening / closing lid 120.As a result, the cable main body 151 is always held in a position separated from the inner surface of the opening / closing lid 120, so that the cable main body 151 that bends as the opening / closing lid 120 is opened or closed can be prevented from being damaged due to contact with the inner surface of the opening / closing lid 120 and from deterioration due to heat conduction from the opening / closing lid 120, and flexible deformation of the flexible flat cable 150 can be achieved within the cable holding area CA.

[0059] Furthermore, the opening / closing cover 120 is provided with a cable base portion 121d, located near the cable fall prevention portion 121b and on the opposite side from the hinge portion 140, which separates the flexible flat cable 150 from the inner surface of the opening / closing cover 120 in a non-contact state, and a cable fixing portion 121e which fixes the cable main body 151 to the cable base portion 121d.As a result, the range in which bending occurs due to excess length of the cable main body 151 is limited to the area between the cable fixing portion 121e and the hinge portion 140, and therefore it is possible to prevent the cable main body 151, which has excess length due to the opening / closing operation of the opening / closing cover 120, from bending near the electrical connection portion and breaking.

[0060] In addition to these, the opening / closing lid is provided with a pressure adjustment unit 130 in the lid internal space IS, and the cable width direction regulating unit 121a is arranged facing the lid internal space IS at a position between the pressure adjustment unit 130 and the hinge unit 140 in the lid internal space IS. Therefore, the cable width direction regulating unit 121a regulates the movement of the cable main body 151 in the cable width direction within a predetermined range at the position between the pressure adjustment unit 130 and the hinge unit 140 where the amount of movement of the cable main body 151 due to excess length generated by the opening / closing operation of the opening / closing lid 120 can be greatest, so that it is possible to more reliably prevent breakage of the cable main body 151 caused by excessive movement in the width direction and bending when the opening / closing lid 120 is opened or closed.
