  The operation of the lock release means 13 will be described with reference to FIGS. FIG. 7 is a partial cross-sectional view for explaining the operation of the lock release means 13, the release member 2 m and the lock member 47. FIG. 8 is a partial sectional view for explaining the operation of the lock release means 13 and the release member 2m. FIG. 9 is a perspective view of the lock release means 13. FIG. 10 is a perspective view of the release member 2m. 11A and 11B are perspective views for explaining a change in position due to the operation of the unlocking means 13, wherein FIG. 11A is a perspective view before the operation, and FIG. 11B is a perspective view in a state where the lid body 10 is opened by the operation.

  FIG. 9 shows the unlocking means 13. The unlocking means 13 includes an engaging portion 13f that is rotatably engaged with a fulcrum 13a (see FIG. 2) provided on the main body 2, and an operation portion 13c that is pressed by a user with a finger. The part 13f and the operation part 13c are in a substantially L-shaped positional relationship in a side view. The locking portion 13f is substantially U-shaped and locked to the fulcrum 13a and is provided on the end (upper end) side of the L-shaped long side (vertical portion), and the operation portion 13c is the L-shaped short side. It is provided on the tip (front end) side of the side (portion in the front-rear direction). The operation unit 13c has an upward slope from the front part to the rear part. That is, an arcuate inclined portion 13d having a substantially center at the intersection of the long side and the short side is provided at a corner portion connecting the long side and the short side at a substantially right angle, and the operation portion 13c It is provided in the middle of the arc of the inclined portion 13d that is easy to push on the stomach, and also has a role of anti-slip.

  The release member 2m of FIG. 10 includes a connecting portion 2t at the top, and includes a side surface 2u bent forward at the left and right ends of the connecting portion 2t, and a shaft through hole 2r at the bottom of the side surface 2u. A release portion pressing portion 2n is provided above the side surface 2u. The left and right end portions of the connecting portion 2t are provided with a release transmitting portion 2k provided extending downward. A transmission spring 2v (FIG. 8) made of a leaf spring is attached to the release transmission portion 2k.

  11A shows the state of the unlocking means 13 when the unlocking means 13 is not operated, and FIG. 11B shows the unlocking when the lid 10 is opened by operating the unlocking means 13. The state of the means 13 is shown.

  As described above, the unlocking means 13 rotatably locks the locking portion 13f to the fulcrum 13a, and the positional relationship between the fulcrum 13a and the operation portion 13c is a substantially L-shaped positional relationship in side view. When the portion 13c is pushed downward, the operation portion 13c rotates and moves to a position of an imaginary line 13h extending below the fulcrum 13a while drawing an arc centered on the fulcrum 13a.

  In addition, the inclined portion 13d and the operation portion 13c provided in the unlocking means 13 each have a circular arc shape on the side pressed by the finger. Therefore, when the operation unit 13c is pushed downward with the finger pad, when the operation unit 13c moves in the downward direction while drawing an arc centering on the fulcrum 13a while moving downward, the operation unit 13c comes into contact with the finger belly. The contact angle with the arcuate inclined portion 13d is changed. This change has a shape that can naturally change without being conscious when it is pressed by inflating the side of the inclined portion 13d that is pressed by the belly of the finger into an arc shape. Further, by adopting this shape, it is made difficult for the fingertip to hit the substantially L-shaped intersection when pressed.

  Specifically, by pushing down the operation portion 13c in the downward direction of the arrow V, the operation portion 13c rotates as shown in the arrow W to the locking portion 13f that is locked to the fulcrum 13a. As shown, the operation unit 13c moves just below the fulcrum 13a, so that the movement amount G (amount of movement in the front-rear direction) can be secured, so that the lid body 10 can be opened.

  Further, the unlocking means 13 in the state in which the lid body 10 is opened has a structure in which the locking member 47 is unlocked at a position where it has entered the amount of entry G rather than the front side surface 2f provided with the recess 2g. When pressed with the body or tableware together with 2f, the unlocking means 13 can only be pushed to the same surface as the front side surface 2f, and the lid 10 does not open.

The operation of opening the lid 10 by operating the lock release means 13 to release the lock member 47 of the lid 10 will be described with reference to FIGS.
As shown in FIG. 4, the lock member 47 is disposed on the left and right of the inner lid locking lever 53 disposed in the front center portion of the outer lid 4 and is composed of a pair of members. The lock member 47 is locked to the locking portion 2 s provided in the main body 2.

The lock member 47 releases the lock member 47 from the locking portion 2 s by the operation of the lock release means 13 entering inside from the recess 2 g of the front side surface 2 f by the release mechanism provided in the main body 2.
7 and 8 show examples of the release mechanism, and the release shaft 2p is provided with a release member 2m that rotates vertically through the through-hole 2r. Above the release shaft 2p, a release pressing portion 2n that pushes the lock member 47 forward to release from the locking portion 2s is provided, and below the release shaft 2p of the release member 2m, a release transmission portion 2k is provided. The release transmission portion 2k is provided with a transmission spring 2v.

  When the unlocking means 13 is operated by pushing down the operation portion 13c of the unlocking means 13 pivotally supported by the fulcrum 13a from the upper side to the lower side as indicated by the arrow V, the unlocking means 13 is pushed from the front side to the rear side. , As shown by the arrow W.

  A pressing portion 13e for pressing the transmission spring 2v is provided at a position substantially opposite to the operation portion 13c provided in the unlocking means 13. When the unlocking means 13 is pushed, the pushing portion 13e pushes the transmission spring 2v in the direction of arrow T. Then, a force is transmitted from the transmission spring 2v, which is a leaf spring, to the release transmission unit 2k, and the release transmission unit 2k rotates as indicated by an arrow Y. Since the lower side of the release shaft 2p moves in the direction of the arrow Y, the release member 2m is a rigid body and rotates about the release shaft 2p. Therefore, the release pressing portion 2n above the release member 2m rotates as indicated by the arrow Z.

  Then, the release pressing portion 2n rotates and pushes the lock member 47 biased in the direction of arrow u by the spring 47b to the front side to release the lock member 2s from being locked. Then, the lid body 10 is rotated and rotated about the outer lid rotation shaft 44 as a rotation axis by the biasing of the hinge portion 440.

  Here, there is a reason that the pressing portion 13e of the lock releasing means 13 pushes the transmission spring 2v and the transmission spring 2v moves the release transmission portion 2k of the release member 2m.

  It is not preferable that the lid body 10 is opened in a state where the pressure in the inner pot 3 during cooking is high. In order to avoid this, the lid 10 is prevented from opening even if the unlocking means 13 is operated in a state where the pressure in the inner pot 3 is increased during rice cooking.

  When the pressure is increased, the fitting force between the lock member 47 provided on the lid 10 and the locking portion 2s on the main body side is increased, and the fitting force is maintained even when the lock release means 13 is operated with a force of 10 kg. Therefore, the transmission spring 2a is bent and the force is not transmitted to the release member 2m, and the lid 10 is prevented from being opened without releasing the lock between the lock member 47 and the lock portion 2s. When pressure is not applied, such as during heat insulation after cooking, the lock member 47 is released and the lid 10 is opened by operating the lock release means 13 at about 1.5 km.

  As shown in FIG. 5, the lid heater 48 is a heating member for heating the condensation stored in the space between the outer lid inner surface member 43 and the inner lid 5 to steam. The lid heater 48 is attached to the lower surface of the outer lid inner surface member 43. The lid heater 48 is configured, for example, by affixing a heater wire in which a nickel chrome wire resistor is covered with a silicone rubber insulator in a planar shape.

  The inner lid 5 is a member that covers the upper opening 3a of the inner hook 3 when the lid body 10 is closed (see FIG. 2). The inner lid 5 includes an inner lid main body 51 disposed in the central portion of the inner lid 5, an inner lid frame 52 fixed to the outer peripheral portion of the inner lid main body 51, and an inner lid provided at the front end portion of the inner lid frame 52. The lid locking lever 53 and the locking lever urging member 54, the seal packing 55 provided over the entire outer peripheral edge, the tray support members 57 and 58 that support the dew condensation tray 7, and the inner lid body 51 Condensation pan 7 attached to the lower surface, pressure regulating valve 63 attached to the center of the upper surface of inner lid body 51, and steam recovery unit 6 attached to the upper surface of inner lid body 51 so as to cover pressure regulating valve 63 And a lower case 61.

Next, the effect | action of the rice cooker 1 which concerns on embodiment is demonstrated. First, the case of cooking rice will be described.
When cooking rice, as shown in FIG. 2, the unlocking means 13 is operated by operating the operation part 13 c of the unlocking means 13 that enters inside from the recess 2 g of the front side face 2 f with an operational feeling of pressing down from above. Is pushed from the front side toward the back side to unlock the lock member 47 provided in the lid body 10 and opens the lid body 10. Polished rice and water are put into the inner pot 3 and rice cooking is started with the lid 10 closed. As shown in FIG. 5, the steam generated in the inner pot 3 enters the steam flow path 56 between the dew receiving tray 7 and the inner lid 5 from the steam circulation hole 71 d and the dew condensation recovery hole 71 e.

  When the internal pressure in the steam flow path 56 rises above a predetermined pressure, the pressure regulating valve 63 is opened with the steam pressure. Then, the steam in the steam channel 56 flows through the pressure regulating valve 63 toward the ceiling surface 62e in the pressure regulating valve arrangement space 62g. When the inside of the pressure regulating valve arrangement space 62g is filled with steam, it enters the ceiling surface 62e in the steam storage space 62h beyond the partition 62n. When the inside of the steam storage space 62h is filled with steam, the steam enters the ceiling surface 62e in the discharge port arrangement space 62i beyond the partition 62o, and is discharged to the outside from the discharge port 62d.

  In this way, the steam flows so as to meander in the left and right and up and down directions of the steam flow paths 56 and 64, and temporarily enters the pressure regulating valve arrangement space 62g, the steam storage space 62h, and the discharge port arrangement space 62i. Since it is stored, it is difficult to discharge to the outside.

  Further, when the lid 10 is opened, the dew adhering to the lower surface of the dew receiving tray 7 is lowered and enters the steam flow path 56 through the dew collecting hole 71e. As shown in FIG. 5, the dew entering the steam channel 56 is stored on the plate portion 71 a of the dew receiving tray 7. Further, the dew condensation in the steam flow path 64 is temporarily stored in the lower case 61 and then flows out from the dew condensation outlet 61g onto the inner lid 5.

  The dew condensation in the steam channel 56 and on the inner lid 5 is heated by the lid heater 48 to become steam, and the steam flows back in the steam channel 56 and returns to the inner pot 3 to steam the rice. it can.

  Thus, the rice cooker 1 of this embodiment suppresses discharge | evaporating the vapor | steam which generate | occur | produces when cooking rice to the exterior of the rice cooker 1, and it makes steam steam in an appropriate state in the rice cooker 1. Can be. In addition, the rice cooker 1 causes the dew that falls when the lid 10 is released to flow into the lid 10, and causes the dew that has flown into steam again with the lid heater 48 to return it to the inner pot 3. Thus, the vapor pressure in the inner pot 3 can be kept in a good state. For this reason, it can suppress that a rice will be in the dry state.
