Electricity is thereby supplied to the heater unit 340 and the liquid in the liquid container 320 is heated. It should be noted that a configuration similar to that of a conventionally known electric kettle can be applied to the power supply base 600 .

<Regarding the operation of releasing the state in which the lid unit is locked with respect to the main unit in the electric kettle according to the embodiment of the present invention and the operation of each mechanism associated with the operation>
In the electric kettle 100 according to the embodiment of the present invention, the locking mechanism 550 of the lid unit 500 can lock the lid unit 500 with respect to the main unit 300 when the lid unit 500 is attached to the main unit 300 . Then, the user can release the state in which the lid unit 500 is locked with respect to the main unit 300 (hereinafter referred to as the “locked state”) by operating the lock mechanism 550 via the operation lever 560 . (This operation is hereinafter referred to as "unlocking operation"). The operations of the operating lever 560, the locking mechanism 550, and the locking mechanism LM when the unlocking operation is performed will be described below.

First, the locked state will be described with reference to FIGS. 4 and 5. FIG. In the locked state, the claw portion RL2 of the locking lever RL of the locking mechanism LM is locked to the claw receiving portion 352 of the discharge port forming portion 350. As shown in FIG. At this time, the torsion spring TS moves the locking lever of the locking mechanism LM in the direction in which the claw portion RL2 of the locking lever RL of the locking mechanism LM is locked with respect to the claw receiving portion 352 of the discharge port forming portion 350. It biases the claw portion RL2 of RL. In addition, the coil spring CS3 biases the lever stopper LS of the locking mechanism 550, the locking lever RL of the locking mechanism LM, and the bearing portion 580 in the laterally outward direction. In addition, the coil spring CS2 urges the movable ball placing member BP of the lock mechanism 550 and the lever stopper LS of the lock mechanism 550 downward. At this time, the convex fitting portion LS5 of the lever stopper LS of the locking mechanism 550 is fitted with the concave fitting portion RL1a of the locking lever RL of the locking mechanism LM. As a result, the locking lever RL of the locking mechanism LM cannot rotate about the axis AX (that is, is locked). Also, in the locked state, the height position of the operating lever 560 and the height position of the open/close button 530 are substantially the same.

Next, the unlocking operation will be described with reference to FIGS. 10 and 11. FIG. The user hooks the fingers of one hand on the flange 562 of the operating lever 560 and lifts the operating lever 560 upward while holding down the main unit 300 with the other hand. At this time, in conjunction with the movement of the operating lever 560, the moving ball placing member BP of the locking mechanism 550 and the lever stopper LS of the locking mechanism 550 are also lifted upward against the biasing force of the coil spring CS2. As a result, the moving ball 570 placed on the central portion of the pedestal portion BP3 of the moving ball placing member BP of the lock mechanism 550 in plan view is pushed into the central portion 511a of the moving ball receiving portion 511 of the top surface member 510, The user cannot lift up only the operating lever 560, the moving ball placing member BP of the locking mechanism 550, and the lever stopper LS of the locking mechanism 550 any further. Also, this operation causes the convex fitting portion LS5 of the lever stopper LS of the locking mechanism 550 to come out of the concave fitting portion RL1a of the locking lever RL of the locking mechanism LM. As a result, the fitting state between the convex fitting portion LS5 of the lever stopper LS of the locking mechanism 550 and the concave fitting portion RL1a of the locking lever RL of the locking mechanism LM is completely released, and the locking mechanism LM is locked. The lever RL becomes rotatable around the axis AX, and the locked state is released. Further, when the unlocking operation is performed, even if the user lifts the operation lever 560 upward without pressing the body unit 300 with the other hand, the body unit 300 cannot be lifted upward. This is because the force required for the unlocking operation, that is, the force required to lift the moving ball mounting member BP of the locking mechanism 550 and the lever stopper LS of the locking mechanism 550 upward against the biasing force of the coil spring CS2 is This is because the biasing force of the coil spring CS2 is adjusted so as to be smaller than the force required to lift the unit 300. Note that if the liquid container 320 contains liquid, the weight of the liquid container 320 becomes even heavier, and the same result is obtained. Further, when the unlocking operation is performed, the height position of the operating lever 560 becomes higher than the height position of the open/close button 530 .

Next, a method for removing the lid unit 500 from the main unit 300 will be described. After the lock release operation, the user lifts the operation lever 560 further upward while hooking the finger on the collar portion 562 of the operation lever 560, thereby lifting the entire lid unit 500 upward. At this time, while the claw portion RL2 of the locking lever RL of the locking mechanism LM is in contact with the upper end portion of the claw receiving portion 352 of the discharge port forming portion 350, the locking lever RL of the locking mechanism LM is moved upward. As it rotates about the axis AX while being lifted against the biasing force of the torsion spring TS, the pawl portion RL2 of the locking lever RL of the locking mechanism LM finally reaches the pawl receiving portion of the outlet forming portion 350. It is positioned above 352. Therefore, the user can remove the lid unit 500 from the main unit 300 . When the pawl portion RL2 of the locking lever RL of the locking mechanism LM reaches the upper side of the inclined portion 353 of the discharge port forming portion 350, the torsion spring TS again causes the upper surface to become perpendicular to the axis of the lid unit 500. It is biased to be substantially parallel. Then, when the lid unit 500 is removed from the main unit 300 and the user releases the finger from the flange 562 of the operation lever 560, the movable ball placing member BP of the lock mechanism 550 and the lever stopper LS of the lock mechanism 550 are moved by the coil spring CS2. is urged downward again by Then, a fitting state is formed between the convex fitting portion LS5 of the lever stopper LS of the locking mechanism 550 and the concave fitting portion RL1a of the locking lever RL of the locking mechanism LM. That is, the lid unit 500 completely removed from the main unit 300 is in the same state as the lid unit 500 shown in FIGS. 4 and 5 when only the lid unit 500 portion shown in FIGS. 4 and 5 is viewed. . Further, when the lid unit 500 is removed from the main unit 300, even if the user lifts the entire lid unit 500 upward without pressing the main unit 300 with the other hand, the main unit 300 cannot be lifted upward. . This is done by lifting the claw portion RL2 of the locking lever RL of the locking mechanism LM in contact with the upper end portion of the claw receiving portion 352 of the discharge port forming portion 350 and lifting the torsion spring TS around the axis AX. This is because the biasing force of the torsion spring TS is adjusted so that the force required to rotate against the force is smaller than the force required to lift the main unit 300 . Note that if the liquid container 320 contains liquid, the weight of the liquid container 320 becomes even heavier, and the same result is obtained.

<Regarding the operation to lock the electric kettle according to the embodiment of the present invention>
Here, referring to FIG. 12 and FIG. 13, the lid unit 500 removed from the main body unit 300 is reattached to the main body unit 300, and the lid unit 500 is locked with respect to the main body unit 300 (operation to be locked). I will explain while First, the user pushes the lid unit 500 until the claw portion RL2 of the locking lever RL of the locking mechanism LM reaches the upper side of the inclined portion 353 of the discharge port forming portion 350 . Then, the user further pushes the lid unit 500 until the pawl portion RL2 of the locking lever RL of the locking mechanism LM reaches the lower side of the pawl receiving portion 352 of the discharge port forming portion 350 . At this time, the lower surface of the claw portion RL2 of the locking lever RL of the locking mechanism LM abuts against the inclined portion 353 of the discharge port forming portion 350, thereby causing the lever stopper LS of the locking mechanism 550 and the locking lever of the locking mechanism LM to contact. RL and bearing portion 580 slide inward against the biasing force of coil spring CS3 (see FIGS. 12 and 13). Then, when the upper surface of the claw portion RL2 of the locking lever RL of the locking mechanism LM reaches the lower side of the upper end portion of the claw receiving portion 352 of the discharge port forming portion 350, the claw portion of the locking lever RL of the locking mechanism LM RL2 is engaged with the pawl receiving portion 352 of the outlet forming portion 350 . Further, in this state, the locked state is maintained in which the claw portion RL2 of the locking lever RL of the locking mechanism LM is prevented from rotating.

<Regarding blocking of unlocking operation at the time of tilting in the electric kettle according to the embodiment of the present invention>
If the unlocking operation is possible while the kettle body 200 is tilted, the lid unit 500 may be removed from the body unit 300 and the liquid in the liquid container 320 may flow out. Therefore, the electric kettle 100 according to the embodiment of the present invention is designed so that the unlocking operation is prevented by the unlocking prevention structure RP when the kettle body 200 is tilted. 14 and 15, an unlock prevention structure RP that prevents an unlock operation when the kettle body 200 is tilted will be described below. 14 and 15 show a state in which the kettle body 200 is tilted to the left. First, when the kettle main body 200 is tilted in the locked state, the moving ball 570 placed on the center of the pedestal portion BP3 of the moving ball placing member BP of the locking mechanism 550 in plan view moves to the position where the moving ball of the locking mechanism 550 is placed. It rolls in the tilting direction on the pedestal portion BP3 of the member BP. At this time, the moving ball 570 rolls between the guide portions BP3a of the moving ball placing member BP of the lock mechanism 550 formed in the tilting direction. In this state, when the operating lever 560 is lifted to perform the unlocking operation, the moving ball 570 is pushed into the peripheral portion 511 b of the moving ball receiving portion 511 of the top member 510 . In such a case, unlike when the movable ball 570 is pushed into the center portion 511a of the movable ball receiving portion 511 of the upper member 510 (see FIGS. 10 and 11), the convex fitting portion LS5 of the lever stopper LS of the lock mechanism 550 and the recessed fitting portion RL1a of the locking lever RL of the locking mechanism LM are not released. That is, since the concave fitting portion RL1a of the locking lever RL of the locking mechanism LM is fitted into the convex fitting portion LS5 of the lever stopper LS of the locking mechanism 550, the locking lever RL of the locking mechanism LM is , are prevented from rotating about the axis AX. Therefore, when the kettle body 200 is tilted, the claw portion RL2 of the locking lever RL of the locking mechanism LM is kept locked to the claw receiving portion 352 of the outlet forming portion 350 (that is, locked). release operation is blocked).

<Regarding the opened/closed state of the liquid path in the electric kettle according to the embodiment of the present invention>
Here, the opening/closing state of the liquid path for pouring the liquid in the liquid container 320 from the spout 301 into a container such as a cup or a cup (during liquid ejection) will be described. First, when the on-off valve 540 is closed (that is, when the on-off button 530 is not pressed downward), the packing 543 of the on-off valve 540 is in close contact with the bottom surface of the bottom plate member 520 (see FIG. 3). (See FIG. 5). As a result, the liquid path is closed (that is, the inside of the liquid container 320 becomes a substantially closed space). Therefore, even if the kettle body 200 tilts when the on-off valve 540 is closed, the liquid does not flow directly from between the on-off valve 540 and the lower surface of the bottom plate member 520 to the discharge path DP. Therefore, it is possible to prevent a large amount of liquid from leaking from the spout 301 when the kettle body 200 is accidentally overturned. On the other hand, when the on-off valve 540 is in the open state (that is, when the on-off button 530 is pressed downward), the packing 543 of the on-off valve 540 is separated from the lower surface of the bottom plate member 520, and the liquid container 320 is closed. The top is open. This opens the liquid flow path. Note that once the open/close button 530 is pressed downward, the state in which the open/close button 530 is pressed by a button locking mechanism (not shown), that is, the state in which the liquid flow path is opened is maintained. Then, the user can pour the liquid in the liquid container 320 into a container such as a cup or a cup by tilting the kettle body 200 toward the spout 301 with the liquid flow path open. Thereafter, when the user presses the open/close button 530 again, the pressed state of the open/close button 530 is released, and the open/close valve 540 and the open/close button 530 are returned upward by the biasing force of the coil spring CS1. As a result, the opening/closing valve 540 closes the liquid flow path again.
