As shown in Fig. 5, Fig. 8, Fig. 12 and Fig. 13, the bottom wall side lead wire holding portion Ab8 is formed on the left part of the front part of the base portion Ab1 and serves to hold the lead wire AL1 of the speaker AL.

[0029] As shown in FIG. 3, the cover member Ac is mainly formed of a lower cover part Ac1 and a rear cover part Ac2. The lower cover part Ac1 has a substantially rectangular shape in a plan view, and is attached to the bottom wall Ab to cover the blower fan 115 from below, as shown in FIG. 3. As shown in FIG. 3, the lower cover part Ac1 has an intake port Ac1a for drawing air outside the housing 111 into the inside. When the blower fan 115 is driven, the outside air is drawn into the housing 111 through the intake port Ac1a, and the heated air inside is discharged to the outside of the system from the exhaust port Ab1a of the base part Ab1 of the bottom wall Ab by the air flow generated by the drawing. The rear cover part Ac2 extends upward from the rear end part of the lower cover part Ac1, as shown in FIG. 3. As shown in FIG. 3, rear cover part Ac2 forms the lower rear end of the side surface of main body 110, and covers automatic retractable power cord unit 120 from the rear side.

[0030] (1-1-2) Shoulder member The shoulder member 111c is a member made of a metal such as stainless steel, and is disposed inside the container 111a by fitting into the side wall Aa of the container 111a through the upper opening of the side wall Aa, as shown in Figs. 3 and 4. As shown in Figs. 3 and 4, the shoulder member 111c is mainly formed of a bottom wall Ca, a curved portion Cb, a flange portion Cc, and a vertical wall Cd. The bottom wall Ca has a substantially rounded rectangular shape in a plan view (see Fig. 4). As shown in Fig. 3, the flange member Da of the protective frame 111d is attached to the lower surface of the bottom wall Ca. An insertion opening for the inner pot 130 is formed in the bottom wall Ca from the front end to the rear (see Figs. 3 and 4). In addition, openings are formed on the left and right sides of the front end of the bottom wall portion Ca (more specifically, the area in front of the insertion opening of the inner bowl 130) for inserting the upper extension wall portion and the claw portion LD1 of the stopper LD of the lever mechanism 119 (see FIG. 4). In addition, an opening is formed on the rear end of the bottom wall portion Ca (more specifically, the area behind the insertion opening of the inner bowl 130) for inserting the fixing portion 153 of the hinge mechanism 150 (see FIG. 3). As shown in FIG. 3 and FIG. 4, the curved portion Cb extends upward while curving from the outer end of the bottom wall portion Ca. As shown in FIG. 3, the flange member Da of the protective frame 111d is attached to the lower surface of the curved portion Cb in the same way as the lower surface of the bottom wall portion Ca. As shown in FIG. 3, the flange portion Cc extends outward from the upper end of the curved portion Cb. The vertical wall portion Cd has a substantially rectangular shape in a front view, and extends upward from the front edge of an opening (opening for inserting the fixing portion 153 of the hinge mechanism 150) at the rear end of the bottom wall portion Ca, as shown in Fig. 3 and Fig. 4. The left end, upper end, and right end of the vertical wall portion Cd are covered with the hinge cover 154 of the hinge mechanism 150 by covering the vertical wall portion Cd with the hinge cover 154 of the hinge mechanism 150 (see Fig. 3 and Fig. 4). The shoulder member 111c also serves to reflect upward the light of the LED 147 guided by the light guide member 148 when the cover body 140 is in the closed state. In order to efficiently reflect the light of the LED 147 guided by the light guide member 148, the surface of the shoulder member 111c may be subjected to a mirror finish.

[0031] (1-1-3) Protective frame The protective frame 111d has the function of housing the inner pot 130, and is made of, for example, resin. As shown in Figures 3, 11 and 12, the protective frame 111d is mainly composed of three members: a flange member Da, an intermediate member Db and a bottom member Dc. These components will be described in detail below.

[0032] The flange member Da has a generally rounded rectangular shape in plan view, and as shown in Figs. 3, 11 and 12, constitutes the upper part of the protective frame 111d, and is connected to the intermediate member Db and is connected to the bottom wall Ab of the container 111a by a spacer 111e. An insertion opening for the inner pot 130 is formed in the center of the flange member Da (see Fig. 3). The flange member Da also has an opening (not shown) for inserting the upper extension wall and the claw LD1 of the stopper LD of the lever mechanism 119. The flange member Da also has a first bearing portion (not shown) for mounting the first rotation shaft LE of the lever mechanism 119 and a second bearing portion (not shown) for mounting the second rotation shaft LF of the lever mechanism 119 in the lower part of the front end of the flange member Da. 3, a fixing portion 153 of the hinge mechanism 150 is attached to the rear end of the flange member Da, which passes through an opening at the rear end of the bottom wall portion Ca of the shoulder member 111c. The flange member Da is also formed with a screw receiving portion Da1 that is disposed inside the cylindrical wall portion Ea5 of the spacer 111e and has a substantially cylindrical shape (see FIG. 11). With the screw receiving portion Da1 disposed inside the cylindrical wall portion Ea5 of the spacer 111e, a screw (not shown) is inserted into the screw receiving portion Da1 through the screw receiving hole Ea4a in the top wall portion Ea4 of the spacer 111e (see FIG. 11).

[0033] The intermediate member Db is a substantially cylindrical member, and constitutes the middle part of the protective frame 111d and is connected to the flange member Da and the bottom member Dc as shown in Fig. 3, 11 and 12. As shown in Fig. 3, a heat retention heater HT is disposed inside the intermediate member Db.

[0034] The bottom member Dc is a bowl-shaped member that opens upward, and constitutes the lower part of the protective frame 111d and is connected to the intermediate member Db, as shown in Figures 3, 11, and 12. An opening for passing a center sensor 114 is formed in the center of the bottom wall of the bottom member Dc (see Figure 3). As shown in Figures 3, 11, and 12, an induction heating coil 113 is disposed on the outside of the bottom wall and the curved wall part of the bottom member Dc.

[0035] (1-1-4) Spacer Four spacers 111e are arranged above the base part Ab1 of the bottom wall Ab of the housing 111a, below the flange member Da of the protective frame 111d, inside the side wall Aa of the housing 111a, and outside the induction heating coil 113, so as to face closely to the side wall Aa of the housing 111a, away from the induction heating coil 113. In addition, the spacers 111e are arranged so that one of the four second screw receiving parts Ab7 formed on the base part Ab1 of the bottom wall Ab of the housing 111a is covered by a screw receiving part Ea8 (described later) and a cylindrical wall part Ea9 (described later) of one spacer 111e (see FIG. 5, FIG. 11 to FIG. 13). The spacers 111e play a role of connecting the bottom wall Ab of the housing 111a and the flange member Da of the protective frame 111d. As shown in Figs. 10 to 13, the spacer 111e is mainly formed of a base portion Ea1, a right side wall portion Ea2, a left side wall portion Ea3, a top wall portion Ea4, a cylindrical wall portion Ea5, a lead wire mounting wall portion Ea6, a lead wire holding portion Ea7, a screw receiving portion Ea8, and a tube wall portion Ea9. As shown in Figs. 10 to 13, the base portion Ea1 extends upward while curving, and then extends straight upward. As shown in Figs. 10, 11, and 13, the right side wall portion Ea2 extends rearward from the right end of the base portion Ea1. As shown in Figs. 11 and 12, the left side wall portion Ea3 extends rearward from the left end of the base portion Ea1. As shown in Figs. 10, 11, and 13, the top wall portion Ea4 extends rearward from the upper end of the base portion Ea1. As shown in Fig. 10, a screw receiving hole Ea4a is formed in a portion of the top wall portion Ea4 that is inside the cylindrical wall portion Ea5. As shown in Figs. 10, 11, and 13, the cylindrical wall portion Ea5 has a substantially cylindrical shape and extends upward from the top wall portion Ea4 so as to surround the screw receiving hole Ea4a of the top wall portion Ea4. As described above, with the screw receiving portion Da1 of the flange member Da of the protective frame 111d disposed inside the cylindrical wall portion Ea5, a screw (not shown) is inserted into the screw receiving portion Da1 of the flange member Da of the protective frame 111d through the screw receiving hole Ea4a of the top wall portion Ea4 (see Fig. 11). As a result, the spacer 111e is fastened to the flange member Da of the protective frame 111d.As shown in Figs. 10, 11 and 13, the lead wire mounting wall Ea6 extends rightward from the rear end of the right side wall Ea2, extends upward while curving, and then extends straight upward. When the spacer 111e is disposed as described above, the orientation of the spacer 111e is adjusted so that the rear surface of the lead wire mounting wall Ea6 faces the opposite side to the induction heating coil 113 side, as shown in Fig. 11. Also, as shown in Figs. 10, 11 and 13, a notch Ea6a is formed in the vertical middle part of the lead wire mounting wall Ea6. As shown in Figs. 11 to 13, a part of the lead wire AL1 of the speaker AL is attached to the spacer 111e in which the screw receiving part Ea8 and the cylindrical wall part Ea9 cover the second screw receiving part Ab7 formed on the front left part of the base part Ab1 of the bottom wall Ab of the housing body 111a. As shown in Fig. 11 and Fig. 13, in this spacer 111e, the lead wire AL1 of the speaker AL enters the rear side of the lead wire mounting wall portion Ea6 through the notch Ea6a, and a part of the lead wire AL1 of the speaker AL is attached to the rear surface of the lead wire mounting wall portion Ea6 so as to extend in the up-down direction. As shown in Fig. 10, Fig. 11 and Fig. 13, the lead wire holding portion Ea7 is formed on the upper end side of the lead wire mounting wall portion Ea6 and has a substantially hook shape. The lead wire holding portion Ea7 plays a role of holding the lead wire AL1 of the speaker AL. As shown in Fig. 10, Fig. 12 and Fig. 13, the screw receiving portion Ea8 extends forward from the lower end of the base portion Ea1. Also, as shown in Fig. 10, a screw receiving hole Ea8a is formed in the screw receiving portion Ea8. As shown in Figures 10, 12 and 13, the cylindrical wall portion Ea9 extends downward from the outer end of the screw receiving portion Ea8. As described above, with the screw receiving portion Ea8 and the cylindrical wall portion Ea9 covering the second screw receiving portion Ab7 of the bottom wall Ab of the housing body 111a, the screw SC2 is inserted into the second screw receiving portion Ab7 of the bottom wall Ab of the housing body 111a through the screw receiving hole Ea8a of the screw receiving portion Ea8. This causes the spacer 111e to be fastened to the bottom wall Ab of the housing body 111a.

[0036] (1-2) First packing The first packing PK1 is made of an elastic material such as rubber or elastomer, and has a generally circular ring shape (see Fig. 3). As shown in Fig. 3, the first packing PK1 is disposed between the flange member Da and the intermediate member Db, and serves to close the gap between the flange member Da and the intermediate member Db over the entire circumference.

[0037] (1-3) Second packing The second packing PK2 is made of an elastic material such as rubber or elastomer, and has a substantially circular ring shape (see FIG. 3). The second packing PK2 also serves to seal the gap between the intermediate member Db and the bottom member Dc over the entire circumference (see FIG. 3).

[0038] (1-4) Pot placement part The pot placement part 112 is a substantially annular member made of resin or the like, and is fitted into the insertion opening for the inner pot 130 in the bottom wall part Ca of the shoulder member 111c and the insertion opening for the inner pot 130 in the flange member Da of the protective frame 111d, as shown in FIG. 3. The pot placement part 112 is also formed with a high step part 112a (see FIG. 3) and a low step part (not shown). The high step part 112a is one step higher than the low step part, and is formed at the front and rear parts of the pot placement part 112 as shown in FIG. 3, and is located above the bottom wall part Ca of the shoulder member 111c. As shown in FIG. 3, when the inner pot 130 is accommodated in the protective frame 111d, the flange part 133 of the inner pot 130 is placed on the high step part 112a. This prevents the inner pot 130 from coming into contact with the metal shoulder member 111c. The low stage is formed on the left and right sides of the pot mounting portion 112, and is located above the bottom wall portion Ca of the shoulder member 111c. When the inner pot 130 is housed in the protective frame 111d, the flange portion 133 of the inner pot 130 is not placed on the low stage. As a result, a gap is formed between the low stage and the flange portion 133 of the inner pot 130, and the inner pot 130 housed in the protective frame 111d can be easily removed by inserting a finger into this gap.

[0039] (1-5) Induction heating coil Induction heating coil 113 is an induction heating source that inductively heats inner pot 130, and as described above, is disposed on the outside of the bottom wall and curved wall portion of bottom member Dc of protective frame 111d.

[0040] (1-6) Heater The warming heater HT is an annular heater used during warming operation, and is disposed inside the intermediate member Db of the protective frame 111d as described above, and is disposed outside the cylindrical wall portion 132 of the inner pot 130 when the inner pot 130 is housed in the protective frame 111d as shown in Fig. 3. Note that the warming heater HT may be used not only during warming operation, but also during rice cooking operation.

[0041] (1-7) Center sensor The center sensor 114 is a sensor for detecting the temperature of the inner bowl 130 and for detecting the presence or absence of the inner bowl 130, and as shown in Fig. 3, it protrudes upward through an opening in the bottom member Dc of the protective frame 111d. The center sensor 114 is biased upward by a biasing member such as a coil spring. In other words, the center sensor 114 is in a state in which it can freely protrude and retract in the vertical direction. When the inner bowl 130 is housed in the protective frame 111d, the center sensor 114 comes into contact with the bottom wall portion 131 of the inner bowl 130 to measure the temperature of the inner bowl 130.

[0042] (1-8) Speakers The speaker AL is responsible for sounding notifications to people when cooking starts and ends, and outputs sounds based on commands from the microcomputer MC on the microcomputer board CB via the relay board RB. As described above, the speaker AL is disposed inside the cylindrical wall part Ab4 of the bottom wall Ab of the container 111a, and is attached directly above the speaker hole Ab1b in the base part Ab1 of the bottom wall Ab of the container 111a.

When the blower fan 115 is driven, outside air is sucked in through the intake port Ac1a of the lower cover part Ac1 of the cover member Ac of the housing 111a, flows into the housing 111, and is sent upward as it is. The outside air sent upward is supplied to the control board 118 and the like through the heat sink 116, cooling them.

[0046] (1-12) Heat sink The heat sink 116 is a component for efficiently exchanging heat with the outside air, and is disposed above the blower fan 115 as shown in FIG.

[0047] (1-13) Control board The control board 118 is a board that constitutes a power supply circuit and has several heat generating components mounted thereon. The control board 118 is accommodated in the rear space of the housing 111 as shown in Fig. 3, and is communicatively connected to the microcomputer board CB.

[0048] (1-14) Automatic retractable power cord unit Automatic rewind power cord unit 120 is composed of a power cord (not shown) and an automatic rewind mechanism (not shown), and is housed in the rear space of housing 111 as shown in FIG. 3. The power cord is composed of an attachment plug, an electric wire, and the like. The attachment plug is disposed at the tip of the electric wire. The electric wire is wound around the automatic rewind mechanism so as to be freely extensible.

[0049] (1-15) Lever mechanism Lever mechanism 119 is for opening and closing cover 140, and as shown in Figures 1 to 3, is mainly composed of an operating part LA, a lever body LB, a transmission member LC, a stopper LD, a first rotating shaft LE, a second rotating shaft LF, a first torsion spring LG, a second torsion spring LH, and a third torsion spring (not shown), etc. These components will be described in detail below.

[0050] The operating part LA is a member that is pressed down by a person when changing the cover 140 from a closed state to an open state, and is disposed in front of the front wall portion of the side wall Aa of the housing body 111a as shown in Figs. 1 to 3. The operating part LA is fastened to the lever main body LB by a screw or the like as shown in Fig. 3. Therefore, a person can press down the operating part LA to press down the lever main body LB via the operating part LA.

[0051] As shown in FIG. 3, the lever body LB is a plate member extending in the front-rear direction. As shown in FIG. 3, the lever body LB is provided so as to pass through an opening Aa1 in the front wall portion of the side wall Aa of the housing body 111a, and the front portion of the lever body LB protrudes from the front wall portion of the side wall Aa of the housing body 111a. In this way, the lever body LB is disposed closer to the front side of the main body 110. As described above, the operating part LA is fastened to the lever body LB, and in this state, the front portion of the lever body LB is covered by the operating part LA. The lever body LB is formed with a bearing hole for passing the first rotation shaft LE. The lever body LB is rotatable around the first rotation shaft LE, and is biased by the first torsion spring LG in the clockwise direction around the first rotation shaft LE as viewed from the right side.

[0052] The transmission member LC has a bearing hole for passing the second rotating shaft LF (see FIG. 3), and the transmission member LC is biased by the second torsion spring LH in a counterclockwise direction about the second rotating shaft LF in a right side view, and is attached to the stopper LD. When the lever body LB rotates about the first rotating shaft LE against the biasing force of the first torsion spring LG, the transmission member LC is rotated by the lever body LB in a clockwise direction about the second rotating shaft LF in a right side view, and applies a force to the stopper LD to rotate together with the stopper LD. When the lid body 140 is in a closed state and pressure cooking is not performed, when the transmission member LC is rotated to apply a force to the stopper LD, the stopper LD rotates about the second rotating shaft LF against the biasing force of the third torsion spring. Then, the state in which the claw portion LD1 of the stopper LD is locked to the locked portion 149 of the lid body 140 is released, and the lid body 140 is in the open state. Furthermore, when the lid body 140 is in the closed state and pressure cooking is being performed, the stopper LD does not rotate about the second rotation shaft LF even if a force is applied to the stopper LD by rotating the transmission member LC. Therefore, when pressure cooking is being performed, the closed state of the lid body 140, that is, the state in which the claw portion LD1 of the stopper LD is locked to the locked portion 149 of the lid body 140, is maintained.

[0053] The stopper LD is a member formed of metal or the like, and is mainly formed of a base portion (not shown), an upper extended wall portion (not shown), a claw portion LD1 (see FIG. 4), a front extended wall portion (not shown), and the like. The base portion is a plate member having a substantially rectangular shape. The upper extended wall portion extends upward from the left and right ends of the base portion. As shown in FIG. 4, the claw portion LD1 extends forward from the upper end of the upper extended wall portion. When the cover body 140 is in a closed state, the claw portion LD1 is engaged with the engaged portion 149 of the cover body 140. The front extended wall portion extends forward from the left and right ends of the base portion. The front extended wall portion is formed with a bearing hole for passing the second rotating shaft LF. By passing the second rotating shaft LF through this bearing hole, the stopper LD becomes rotatable around the second rotating shaft LF. The stopper LD is biased by a third torsion spring in a counterclockwise direction about the second rotation shaft LF when viewed from the right side.

[0054] As described above, the first rotating shaft LE is attached to the first bearing portion of the flange member Da of the protective frame 111d. At this time, the first rotating shaft LE is inserted into the inside of the coil portion of the first torsion spring LG and into the bearing hole of the lever main body LB, as shown in FIG.

[0055] As described above, the second rotating shaft LF is attached to the second bearing portion of the flange member Da of the protective frame 111d. At this time, the second rotating shaft LF is inserted through the inside of the coil portion of the second torsion spring LH and the inside of the coil portion of the third torsion spring, as well as through the bearing hole of the transmission member LC and the bearing hole of the front extended wall portion of the stopper LD, as shown in FIG.

[0056] As described above, the first torsion spring LG is a member for biasing the lever main body LB. As described above, the first rotation shaft LE is inserted into the inside of the coil portion of the first torsion spring LG, one end of the first torsion spring LG is attached to the lever main body LB, and the other end of the first torsion spring LG is attached to the flange member Da of the protective frame 111d.

[0057] The second torsion spring LH is a double torsion spring, and as described above, it is a member that biases the transmission member LC and attaches the transmission member LC to the stopper LD. As described above, the second rotating shaft LF is inserted inside both coil portions of the second torsion spring LH, a portion that connects one coil portion and the other coil portion of the second torsion spring LH is attached to the transmission member LC, and both ends of the second torsion spring LH are attached to the stopper LD.

[0058] As described above, the third torsion spring is a member for biasing the stopper LD. As described above, the second rotating shaft LF is inserted inside the coil portion of the third torsion spring, one end of the third torsion spring is attached to the flange member Da of the protective frame 111d, and the other end of the second torsion spring LH is attached to the stopper LD.

[0079] <Features of the rice cooker according to the embodiment of the present invention> (1) In the rice cooker 100 according to the embodiment of the present invention, the spacer 111e is disposed above the base part Ab1 of the bottom wall Ab of the container 111a, below the flange member Da of the protective frame 111d, inside the side wall Aa of the container 111a, and outside the induction heating coil 113, so as to face closely to the side wall Aa of the container 111a away from the induction heating coil 113. In addition, in the spacer 111e covering the second screw receiving part Ab7 formed on the front left part of the base part Ab1 of the bottom wall Ab of the container 111a, a part of the lead wire AL1 of the speaker AL is attached to the rear surface of the lead wire attachment wall part Ea6 of the spacer 111e so as to extend in the vertical direction. Therefore, in the rice cooker 100, the lead wire AL1 of the speaker AL can be prevented from being affected by noise from the induction heating coil 113 as much as possible. Therefore, in the rice cooker 100, the speaker AL can output sound with the best possible quality and volume. Furthermore, in this rice cooker 100, the lead wire mounting wall portion Ea6 of the spacer 111e can prevent at least a part of the lead wire AL1 of the speaker AL attached to the rear surface of the lead wire mounting wall portion Ea6 of the spacer 111e from approaching the induction heating coil 113 as much as possible.

[0080] (2) In the rice cooker 100 according to the embodiment of the present invention, the lead wire AL1 of the speaker AL is held by the bottom-wall-side lead wire holding portion Ab8 of the bottom wall Ab of the container 111a and the lead wire holding portion Ea7 of the spacer 111e. Therefore, in this rice cooker 100, it is possible to reduce the risk that at least a part of the lead wire AL1 of the speaker AL will become misaligned and come close to the induction heating coil 113.

[0081] (3) In the rice cooker 100 according to the embodiment of the present invention, the spacer 111e connects the bottom wall Ab of the container 111a and the flange member Da of the protective frame 111d. Therefore, in this rice cooker 100, the spacer 111e can fix the position of the protective frame 111d relative to the bottom wall Ab of the container 111a.

[0082] (4) In the rice cooker 100 according to the embodiment of the present invention, the cushion member BM is disposed between the speaker AL and the speaker cover CV, and is in contact with both the upper end surface of the speaker AL and the lower surface of the central recess CV1a of the speaker cover CV. Therefore, in this rice cooker 100, it is possible to prevent vibrations caused by sound output from the speaker AL from being transmitted to the speaker cover CV as much as possible.

[0083] (5) In the rice cooker 100 according to the embodiment of the present invention, a square tube wall portion Ab3 is formed in the bottom wall Ab of the housing 111a, and a groove CVa is formed in the speaker cover CV by a top wall portion CV1, an outer wall portion CV2, and an inner wall portion CV3. The speaker cover CV is fastened to the bottom wall Ab of the housing 111a so that the groove CVa fits into the square tube wall portion Ab3 of the bottom wall Ab of the housing 111a. Therefore, in this rice cooker 100, it is possible to prevent as much as possible the positive phase sound output from the lower side of the speaker AL and the opposite phase sound output from the upper side of the speaker AL from canceling each other out.

[0084] (6) In the rice cooker 100 according to the embodiment of the present invention, an opening Ab3a for passing the lead wire AL1 of the speaker AL is formed in the front end of the left wall of the square tube wall portion Ab3 of the bottom wall Ab of the container 111a.
