Description

The present invention relates to a container body, in particular a container body having a container body and a lid body.

In the past, there has been a proposal for an electric kettle with a lid having a detachable mechanism in which a pair of left and right engaging members are provided in the lid, each having an outwardly facing operating piece that is exposed on the lid and allows the thumb and the opposing index finger or ring finger to be hooked separately, and a spring is applied between these engaging members so that the engaging pieces of each engaging member always protrude from two windows provided on the left and right of the diameter line of the peripheral wall of the lid (see, for example, JP 2009-172109 A). In this electric kettle, a locking recess is formed in the lid that engages with the engaging pieces that protrude from two left and right points on the diameter line of the peripheral surface of a recess formed by the shoulder of the lid, facing the detachable mechanism.

JP 2009-172109 A

In the electric kettle described above, when the engaging piece of the detachable mechanism is engaged with the engaging recess of the container, the flat bottom surface of the engaging recess of the container faces the flat top surface of the engaging piece of the detachable mechanism, and the engaging piece of the detachable mechanism is biased by a spring to the side opposite the axial end of the lid. In such a case, the pressure between the flat bottom surface of the engaging recess of the container and the flat top surface of the engaging piece of the detachable mechanism becomes insufficient, and there is a risk that the lid will become unstable in the vertical direction.

The object of the present invention is to provide a container body that can increase the pressure contact force between the locking member of the locking mechanism and the locked portion when the locking member is locked to the locked portion of the main body, and can stabilize the lid as much as possible in the vertical direction.

The container body according to the present invention is
A main body having a pair of left and right engaged portions;
a cover body that is detachably attached to the main body via a locking mechanism having a pair of left and right locking members that can be locked to the locked portion;
A pair of left and right connecting members connectable to the locking member ,
The locking mechanism rotates the locking member about a rotation axis to lock it to the locked portion.

According to the above configuration, when the locking member is locked to the locked portion, it can apply a force to the locked portion in the direction of locking. Therefore, in this container body, when the locking member is locked to the locked portion, the pressure contact force between the locking member and the locked portion can be increased and the lid body can be stabilized as much as possible in the vertical direction compared to when the locking member is biased to the opposite side of the axial side of the lid body. Furthermore, this makes it possible to prevent the sealing property of the seal member from being impaired, even if the container body is provided with a seal member that keeps the main body and the lid body tight when the lid body is attached to the main body.

In the present invention ,
It is preferable that the connecting member renders the engaging member non-rotatable when the engaging member is engaged with the engaged portion.

The above configuration makes it possible to prevent the locking member from accidentally rotating and releasing the locked state when the locking member is locked to the locked portion.

In the present invention,
The locking member is formed with a first fitting portion,
The connecting member is formed with a second fitting portion that can be fitted into the first fitting portion,
It is preferable that the first fitting portion and the second fitting portion are fitted together when the locking member is locked to the locked portion.

The above configuration makes it possible to prevent the locking member from accidentally rotating and releasing the locked state when the locking member is locked to the locked portion.

In the present invention,
The connecting member is movable in a vertical direction, and when connecting with the locking member, the connecting member moves down toward the locking member,
It is preferable that, when the locking member is locked to the locked portion, the locking member abuts against a lower side of the locked portion.

According to the above configuration, when the locking member is locked to the locked portion, the locking member can be released from its non-rotatable state by raising the connecting member. Therefore, in this container body, when the locking member is locked to the locked portion and an operating part is provided that can move up and down relative to the connecting member, the lid can be detached from the main body by simply moving the operating part upward.

In the present invention,
The locking mechanism further includes a biasing member.
It is preferable that the biasing member biases the locking member in a direction in which the locking member is locked to the locked portion.

The above configuration makes it possible to prevent the locking member from accidentally rotating and releasing the locked state when it is locked to the locked portion. When the container body includes this locking member and the above-mentioned connecting member, it is possible to adjust the force required by the user to release the locking member from being locked to the locked portion, or adjust the sealing property of the sealing member, depending on the design of the locking member or the connecting member.

In the present invention,
A moving body connected to the pair of left and right connecting members is further provided,
The connecting member is preferably interlocked with the moving body.

In the present invention,
the connecting member also moves downward in accordance with the downward movement of the movable body, and the connecting member is connected to the locking member to prevent the locking member from rotating;
It is preferable that as the movable body moves upward, the connecting member also moves upward, the connection between the connecting member and the locking member is released and the locking member is released from its non-rotatable state, so that the state in which the locking member is locked to the locked portion can be released.

The upper end of the sidewall member 310 supports the upper end of the discharge port forming portion 350 as shown in FIG. 1, FIG. 3 to FIG. 5. A notch is formed at the upper end of the rear part of the sidewall member 310, and the main body connecting portion 402 of the handle unit 400 is fitted into this notch as shown in FIG. A front protrusion 311 inclined toward the front side is formed at the upper part of the front part of the sidewall member 310.

(1-2) Liquid Container The liquid container 320 is a member capable of storing liquid therein, and is housed inside the sidewall member 310 as described above. As shown in FIG. 3, the liquid container 320 is formed of an inner wall member 321 and a heater plate 322. The inner wall member 321 is a member formed of a resin or a metal such as stainless steel, and has a substantially cylindrical shape, and constitutes the sidewall of the liquid container 320 as shown in FIG. 3. As shown in FIGS. 3 to 5, the lower end of the discharge port forming portion 350 is attached to the upper end of the inner wall member 321. The inner peripheral surface of the inner wall member 321 may be coated with a corrosion-resistant resin (not shown) such as fluororesin. The heater plate 322 is a metal plate material, and covers the lower opening of the inner wall member 321 so as to close it as shown in FIG. 3. That is, the heater plate 322 constitutes the bottom of the liquid container 320. A print heater 341 , which is one component of a heater unit 340 , is disposed on the lower surface of the heater plate 322 .

1 and 3, bottom member 330 constitutes the bottom of main unit 300, is attached to the lower side of side wall member 310, and covers liquid container 320, heater unit 340, etc. from below. Note that bottom member 330 has an opening formed therein to expose the lower end of power supply terminal 342.

(1-4) Heater Unit Heater unit 340, as shown in Fig. 3, is attached to heater plate 322, and is mainly composed of print heater 341 and power supply terminal 342. Print heater 341 serves to heat the liquid in liquid container 320. When connection terminal 602 provided on power supply base 600 is electrically connected to power supply terminal 342, power is supplied from connection terminal 602 to print heater 341. Note that a heater unit of a conventionally known electric kettle can be used as this heater unit 340.

(1-5) Outlet Forming Part The outlet forming part 350 is a member having a substantially cylindrical shape, and is attached to the main unit 300 as shown in Figs. 1 to 3. As described above, the upper end of the outlet forming part 350 is supported by the upper end of the side wall member 310, and the lower end of the outlet forming part 350 is attached to the upper end of the inner wall member 321 of the liquid container 320. Also, as shown in Figs. 1 to 3, a front protrusion 351 that inclines upward toward the front is formed at the upper part of the front part of the outlet forming part 350. The front protrusion 351 is supported by the front protrusion 311 of the side wall member 310 as shown in Figs. 1 and 3. In this way, in the electric kettle 100 according to the embodiment of the present invention, the spout 301 is formed by a part of the outlet forming part 350 (i.e., the front protrusion 351). 4 and 5, an outwardly recessed claw receiving portion 352 is formed in the middle of the left and right portions of the discharge port forming portion 350. A claw portion RL2 of a locking lever RL of a locking mechanism LM of the lid unit 500 is locked to this claw receiving portion 352 (see FIGS. 4 and 5). As shown in FIGS. 4 and 5, an inclined portion 353 inclined outward is formed on the upper side of the claw receiving portion 352. The inclined portion 353 comes into contact with the claw portion RL2 of the locking lever RL of the locking mechanism LM of the lid unit 500 when the lid unit 500 is attached to the main unit 300 or when the lid unit 500 is removed from the main unit 300.

1 to 3, the handle unit 400 is mainly composed of a grip portion 401, a main body connection portion 402, and a dial mechanism 403. Each of these components will be described in detail below.

(2-1) Grip Part Grip part 401 is a member formed of resin or the like, and serves as a handle when a user carries kettle body 200. As shown in Figures 1 to 3, grip part 401 extends downward from the rear part of main body connection part 402.

(2-2) Main Body Connection Portion The main body connection portion 402 is for connecting the handle unit 400 to the main body unit 300. The main body connection portion 402 is fitted into the notch at the upper end of the rear portion of the side wall member 310, as described above.

(2-3) Dial Mechanism Dial mechanism 403 is for adjusting the temperature of print heater 341 of heater unit 340 (i.e., the temperature of the liquid in liquid container 320), and is connected to heater unit 340. Dial mechanism 403 is disposed at the rear of main body connection section 402, as shown in Figures 1 to 3.

(3) Lid unit As shown in Figs. 1 to 5, the lid unit 500 is a detachable, generally cylindrical lid that covers the upper part of the main unit 300. A user can remove the lid unit 500 from the main unit 300 by operating a lock mechanism 550 (described later) via an operating lever 560 provided on the lid unit 500. This allows the user to pour liquid into the liquid container 320 after removing the lid unit 500 from the main unit 300. When heating the liquid in the liquid container 320, the user attaches the lid unit 500 to the main unit 300 to make the inside of the liquid container 320 a closed space. As shown in Figs. 1 to 5, the lid unit 500 is mainly composed of a bottom plate member 520, an opening/closing button 530, an opening/closing valve 540, a lock mechanism 550, a lock mechanism LM, an operating lever 560, an unlocking prevention structure RP, and a seal member 590. Each of these components will be described in detail below.

(3-1) Bottom Plate Member As shown in FIG. 3 to FIG. 5, the bottom plate member 520 mainly constitutes the lower part of the lid unit 500, and is formed by a side wall portion 521 and a bottom wall portion 522. The side wall portion 521 has a substantially cylindrical shape. As shown in FIG. 3 to FIG. 5, the top surface member 510 (described later) is placed on the upper side of the side wall portion 521. As a result, a steam flow space SP1 surrounded by the top surface member 510 and the bottom plate member 520 is formed (see FIG. 3). The steam flow space SP1 plays a role in forming a flow path for the steam generated in the liquid container 320. As shown in FIG. 3, a flow path forming portion 523 is formed in the front part of the side wall portion 521. The flow path forming portion 523 is a portion that opens toward the spout 301 of the kettle body 200. The flow path forming portion 523 forms a discharge path DP that guides the liquid in the liquid container 320 to the spout 301. As shown in FIG. 4, openings 521a are formed on the lower left and right sides of the side wall 521, and the claw RL2 of the lock lever RL of the lock mechanism LM can protrude from the openings 521a. The bottom wall 522 has a substantially circular ring shape in a plan view, and forms a step structure in a vertical cross-sectional view as shown in FIG. 3 to FIG. 5. As shown in FIG. 3 to FIG. 5, an opening/closing valve 540 is disposed on the lower side of the bottom wall 522. Note that, here, as shown in FIG. 3, the bottom wall 522 abuts against the packing 543 of the opening/closing valve 540 when the opening/closing valve 540 is in a closed state. And, the bottom wall 522 does not abut against the packing 543 of the opening/closing valve 540 when the opening/closing valve 540 is in an open state. This makes it possible to guide the liquid in the liquid container 320 to the discharge path DP when the opening/closing valve 540 is in an open state. 3 and 4, a central opening is formed in the center of the bottom wall 522, and the shaft 542 of the on-off valve 540 is fitted into this central opening. As shown in FIG. 3, a rear communication hole 522a is formed in the rear of the bottom wall 522 (i.e., rear of the central opening). When the on-off valve 540 is closed, the rear communication hole 522a comes into contact with the packing 543 of the on-off valve 540 and is closed, and when the on-off valve 540 is open, the rear communication hole 522a is opened and communicates the internal space of the liquid container 320 with the vapor circulation space SP1. As shown in FIG. 3, a front communication hole 522b is formed in the front of the bottom wall 522 (i.e., forward of the central opening and rear of the flow path forming portion 523). As shown in FIG. 3, the front communication hole 522b communicates the vapor circulation space SP1 with the discharge path DP.

(3-2) Opening/Closing Button As shown in Figs. 3 to 5, the opening/closing button 530 is fitted into the opening of the upper surface member 510 and is connected to the tip of the shaft portion 542 of the opening/closing valve 540. As shown in Figs. 2 to 5, the cylindrical wall portion BP2 of the moving ball mounting member BP of the locking mechanism 550 is disposed on the outside of the opening/closing button 530. The opening/closing button 530 is biased upward by a coil spring CS1 disposed so as to surround the shaft portion 542 of the opening/closing valve 540. When the user presses the opening/closing button 530 downward against the biasing force of the coil spring CS1, the opening/closing valve 540 moves downward in conjunction with the pressing action. This causes the opening/closing valve 540 to be in an open state.

(3-3) On-off valve The on-off valve 540 is composed of a valve body 541, a shaft 542, and a packing 543, as shown in Figs. 3 to 5. The valve body 541 has a substantially disk shape, and is disposed below the bottom plate member 520 of the lid unit 500, as shown in Figs. 3 to 5. The shaft 542 is a rod-shaped member extending upward from the rear of the upper surface of the valve body 541, as shown in Figs. 3 and 4. As described above, the shaft 542 is fitted into the central opening of the bottom wall 522 of the bottom plate member 520, and the tip of the shaft 542 is connected to the on-off button 530. The packing 543 has a substantially annular shape, and is attached to the outer edge of the valve body 541, as shown in Figs. 3 to 5.

(3-4) Locking Mechanism The locking mechanism 550 is for locking the lid unit 500 to the main unit 300 (see Figures 4 and 5) when the lid unit 500 is attached to the main unit 300. As shown in Figures 4 and 5, the locking mechanism 550 is mainly composed of a moving ball mounting member BP and a lever stopper LS. These components will be described in detail below.

(3-4-1) Moving Ball Mounting Member As shown in Fig. 4 and Fig. 5, the moving ball mounting member BP is mounted on the upper side of the lever stopper LS and is connected to the lever stopper LS and is also connected to the operating lever 560. As shown in Fig. 2, Fig. 4 and Fig. 6, the moving ball mounting member BP is mainly formed of a base part BP1, a cylindrical wall part BP2, a pedestal part BP3, a first spring mounting part BP4 and a second spring mounting part BP5. Of these parts, the parts that contribute to the lock mechanism 550 are the base part BP1, the cylindrical wall part BP2, the first spring mounting part BP4 and the second spring mounting part BP5. As shown in Fig. 6, the base part BP1 is a plate-like part having a substantially rectangular shape. As shown in Fig. 4, an opening is formed in the center of the base part BP1. As shown in Figures 4 and 6, the cylindrical wall portion BP2 has a substantially cylindrical shape and extends upward from the upper edge of the opening of the base portion BP1. As shown in Figures 3 to 5, the cylindrical wall portion BP2 is sandwiched between the open/close button 530 and the operating lever 560, and is connected only to the operating lever 560. That is, the operating lever 560 and the moving ball mounting member BP (and the lever stopper LS) are interlocked with each other, but the open/close button 530 and the moving ball mounting member BP are not interlocked with each other. For this reason, when the operating lever 560 and the moving ball mounting member BP are lifted upward, the open/close button 530 is not lifted upward, and the height positional relationship between the operating lever 560 and the moving ball mounting member BP and the open/close button 530 changes (see Figures 4 and 5). As shown in Figs. 2, 4 and 6, the pedestal portion BP3 is formed on the left and right sides of the upper surface of the base portion BP1, and has a generally cylindrical shape with the upper portion concave downward (in other words, the upper portion is cut into a generally inverted cone shape). As shown in Figs. 2 and 4, the moving ball 570 is movably placed on the pedestal portion BP3. Also, as shown in Figs. 2 and 6, a convex guide portion BP3a that spreads radially from the center of the pedestal portion BP3 in a plan view is formed on the pedestal portion BP3. As shown in Figs. 2, 4 and 6, the first spring installation portion BP4 is formed on the left and right sides outside the pedestal portion BP3 on the upper surface of the base portion BP1. As shown in Figs. 4 and 6, one end of the coil spring CS2 that urges the moving ball placement member BP and the lever stopper LS downward is fitted into the first spring installation portion BP4. The second spring mounting parts BP5 are formed on the left and right of the center of the lower surface of the base part BP1, and extend outward in the left and right directions, respectively, as shown in Fig. 4. As shown in Fig. 4, one end of the coil spring CS3 that biases the lever stopper LS, the locking lever RL, and the bearing part 580 outward in the left and right directions is fitted into the second spring mounting parts BP5.

(3-4-2) Lever stopper As shown in Fig. 4, Fig. 5, Fig. 7 and Fig. 8, the lever stopper LS is a pair of left and right members, which is connected to the moving ball mounting member BP and is connected to the operating lever 560 via the moving ball mounting member BP. As shown in Fig. 7 and Fig. 8, the lever stopper LS is mainly formed of a base portion LS1, an upper standing wall portion LS2, a lower standing wall portion LS3, a spring installation portion LS4 and a convex fitting portion LS5. Note that only one of the pair of left and right lever stoppers LS is drawn in Fig. 7 and Fig. 8. As shown in Fig. 7, the base portion LS1 is a substantially rectangular plate member in which a recessed portion LS1a is formed on the axial side of the lid unit 500. The moving ball mounting member BP is mounted on the upper side of the base portion LS1, and the lever stopper LS is fitted to the moving ball mounting member BP so as to be slidable and movable. The upper standing wall portion LS2 extends upward from the front and rear portions of the base portion LS1, as shown in Fig. 7 and Fig. 8. When the moving ball placement member BP is placed on the upper side of the base portion LS1, the upper standing wall portion LS2 is fitted into a groove portion (not shown) formed on the lower side of the base portion BP1 of the moving ball placement member BP. The lower standing wall portion LS3 extends downward from the inner edge portion of the recessed portion LS1a of the base portion LS1, as shown in Fig. 4, Fig. 7, and Fig. 8. The spring installation portion LS4 is formed on the inner surface of the lower standing wall portion LS3 (i.e., the surface on the axis side of the lid unit 500), as shown in Fig. 4 and Fig. 7. As shown in Fig. 4, one end of the coil spring CS3 is fitted into the spring installation portion LS4. The protruding fitting portion LS5 extends downward from the front and rear portions of the outer end portion of the base portion LS1 as shown in Figures 5, 7 and 8. The protruding fitting portion LS5 is capable of fitting with the recessed fitting portion RL1a of the locking lever RL, as will be described in detail later.

(3-5) Locking Mechanism The locking mechanism LM is mainly composed of a locking lever RL, a bearing portion 580, and a torsion spring TS, as shown in Figures 4 and 5. These components will be described in detail below.

(3-5-1) Locking Lever As shown in Figs. 4, 5, 9 and 18, the locking lever RL is a pair of left and right members, and can be connected to the lever stopper LS. As shown in Figs. 9 and 18, the locking lever RL is mainly formed of a base portion RL1, a claw portion RL2, an outer wing portion RL3 and an inner wing portion RL4. Note that only one of the pair of left and right locking levers RL is depicted in Figs. 9 and 18. As shown in Figs. 9 and 18, the base portion RL1 has a substantially cylindrical shape. As shown in Figs. 5, 9 and 18, the base portion RL1 has a recessed fitting portion RL1a recessed from the upper side to the lower side at each of the front end portion and the rear end portion, a bearing hole RL1b extending from the front end portion to the rear end portion, and a space RL1c formed in the center portion in the front-rear direction. As shown in FIG. 5, when the claw portion RL2 is biased by the torsion spring TS (see FIG. 9 and FIG. 16) in a direction in which the claw portion RL2 is engaged with the claw receiving portion 352 of the discharge port forming portion 350 of the main body unit 300 (i.e., so that the upper surface of the claw portion RL2 is approximately parallel to a plane perpendicular to the axis of the lid unit 500), the concave fitting portion RL1a fits with the convex fitting portion LS5 of the lever stopper LS. Then, as shown in FIG. 4, FIG. 5, and FIG. 18, the axis AX is inserted into the bearing hole RL1b. Since the axis AX is fixed in the lid unit 500, the locking lever RL is rotatable about the axis AX (see FIG. 10, etc.). Then, as shown in FIG. 4, FIG. 9, and FIG. 18, the torsion spring TS and the cylindrical portion 582 and the columnar portion 583 of the bearing portion 580 are arranged in the space RL1c. As shown in Figures 4, 5, 9 and 18, the claw portion RL2 extends outward from the outer end of the upper part of the base portion RL1 and can be engaged with the claw receiving portion 352 of the outlet forming portion 350 of the main unit 300. In this case, the upper surface of the claw portion RL2 abuts against the claw receiving portion 352 of the outlet forming portion 350 (see Figures 4 and 5). As shown in Figures 9 and 18, the outer wing portion RL3 extends inward from the front end and rear end of the base portion RL1. As shown in Figures 9 and 18, the inner wing portion RL4 extends inward from the front end and rear end of the portion of the base portion RL1 where the space RL1c is formed.

(3-5-2) Bearing The bearing 580 is a pair of left and right members as shown in FIG. 4 and FIG. 5, and defines the height position of the axis AX in the lid unit 500. As shown in FIG. 16 to FIG. 18, the bearing 580 is formed of a base 581, a cylindrical portion 582, a columnar portion 583, a wing portion 584, and a bottom plate portion 585. Note that only one of the pair of left and right bearings 580 is depicted in FIG. 16 to FIG. 18. The base 581 is a plate-like portion having a substantially rectangular shape as shown in FIG. 16. The cylindrical portion 582 has a substantially cylindrical shape as shown in FIG. 16 to FIG. 18, and is formed on the front side of the base 581. The columnar portion 583 has a substantially cylindrical shape as shown in FIG. 16, and is formed in the internal space of the cylindrical portion 582. As shown in FIG. 16, the columnar portion 583 is formed with a bearing hole 583a that runs from the front end to the rear end, and the axis AX is inserted through the bearing hole 583a. As shown in FIG. 16, the torsion spring TS is disposed in the space surrounded by the cylindrical portion 582 and the columnar portion 583. As described above, the cylindrical portion 582 and the columnar portion 583 (and the torsion spring TS) are disposed in the space RL1c of the lock lever RL. As shown in FIG. 16 to FIG. 18, the wing portion 584 is a pair of portions that extend inward from the front end and rear end of the base portion 581. As shown in FIG. 16 to FIG. 18, the bottom plate portion 585 is a plate-like portion formed below the wing portion 584. 16 and 17, the length of the bottom plate 585 in the front-rear direction is greater than the length between the pair of wings 584, and the length of the bottom plate 585 in the left-right direction is less than the length of the wings 584. As shown in FIG. 17, a lower upright wall insertion hole 586 surrounded by the base 581, the wings 584, and the bottom plate 585 is formed in the bearing 580. When the lid unit 500 is locked to the main unit 300, the lower upright wall LS3 of the lever stopper LS is inserted into this lower upright wall insertion hole 586. Moreover, as shown in FIG. 4 and 10, the inner surface of the base 581 of the bearing 580 abuts against at least a part of the outer surface of the lower upright wall LS3 of the lever stopper LS, regardless of whether the lid unit 500 is locked to the main unit 300. Therefore, not only the lever stopper LS but also the bearing portion 580 (and the locking lever RL via the bearing portion 580) is biased outwardly to the left and right by the coil spring CS3.

(3-5-3) Torsion Spring As described above, the torsion spring TS biases the claw portion RL2 of the locking lever RL in a direction to lock the claw portion RL2 of the locking lever RL with the claw receiving portion 352 of the outlet forming portion 350 of the main unit 300 (i.e., biases the claw portion RL2 of the locking lever RL so that the upper surface of the claw portion RL2 of the locking lever RL is approximately parallel to a plane perpendicular to the axis of the lid unit 500). The torsion spring TS is disposed on the outer periphery of the axis AX and in a space surrounded by the cylindrical portion 582 and the columnar portion 583 of the bearing portion 580 (see FIG. 16). The torsion spring TS is disposed in the space RL1c of the locking lever RL together with the cylindrical portion 582 and the columnar portion 583 of the bearing portion 580.

(3-6) Operation Lever The operation lever 560 is operated by the user when the lock mechanism 550 is released, and as described above, is connected to the moving ball mounting member BP of the lock mechanism 550 and is connected to the lever stopper LS of the lock mechanism 550 via the moving ball mounting member BP of the lock mechanism 550. As shown in Figs. 3 to 5, the operation lever 560 is formed of a base portion 561 and a flange portion 562. The base portion 561 has a substantially cylindrical shape, and is fitted into an opening of the upper surface member 510 as shown in Figs. 3 to 5. The flange portion 562 is a substantially disk-shaped portion for the user to support the operation lever 560 with his/her fingers, and extends outward from the upper end portion of the base portion 561 as shown in Figs. 3 to 5. As shown in Figs. 3 to 5, an opening is formed in the center of the flange portion 562, and the open/close button 530 is exposed through this opening. In addition, a groove is formed on the lower surface of the flange 562. This groove functions as a non-slip surface for the user's fingers.

(3-7) Unlock Prevention Structure The unlock prevention structure RP is intended to prevent an operation to release the state in which the lid unit 500 is locked to the main body unit 300 when the kettle body 200 is tilted. As shown in Fig. 4, the unlock prevention structure RP is mainly composed of a moving ball mounting member BP, an upper surface member 510, a moving ball 570, etc.

(3-7-1) Moving Ball Placement Member The moving ball placement member BP constitutes part of the above-mentioned lock mechanism 550, and also constitutes part of the unlocking prevention structure RP. As described above, the moving ball placement member BP is mainly formed of the base portion BP1, the cylindrical wall portion BP2, the pedestal portion BP3, the first spring installation portion BP4, and the second spring installation portion BP5, but of these portions, only the pedestal portion BP3 contributes to the unlocking prevention structure RP. The details of the moving ball placement member BP have already been described, so a detailed description thereof will be omitted here.

(3-7-2) Top Surface Member As shown in Figures 1 to 3, the top surface member 510 is a member having a substantially circular ring shape, and constitutes the top surface of the lid unit 500. That is, an opening is formed in the center of this top surface member 510. As shown in Figures 3 to 5, the opening of the top surface member 510 is fitted with the open/close button 530, the cylindrical wall portion BP2 of the moving ball mounting member BP of the locking mechanism 550, the base portion 561 of the operating lever 560, and the like. In addition, as shown in Figure 4, moving ball receiving portions 511 are formed on the left and right portions of the lower surface of the top surface member 510. The moving ball receiving portion 511 is a portion for receiving the moving ball 570 placed on the moving ball placing member BP of the locking mechanism 550 when the moving ball placing member BP of the locking mechanism 550 moves upward (i.e., for sandwiching the moving ball 570 in cooperation with the moving ball placing member BP of the locking mechanism 550), and is formed of a central portion 511a and a peripheral portion 511b as shown in FIG. 4. The central portion 511a is a recessed portion having a substantially hemispherical shape, and is located above the peripheral portion 511b in a vertical cross-sectional view as shown in FIG. 4. The peripheral portion 511b is a recessed portion having a substantially annular shape (having a substantially semicircular shape in a vertical cross-sectional view), and is formed around the central portion 511a and is located slightly below the central portion 511a in a vertical cross-sectional view as shown in FIG. 4. In addition, as shown in FIG. 4, a spring installation portion 512 is formed outside the moving ball receiving portion 511 on the lower surface of the upper surface member 510. As shown in FIG. 4 , one end of a coil spring CS 2 that urges the moving ball placement member BP of the lock mechanism 550 and the lever stopper LS of the lock mechanism 550 downward is fitted into the spring installation portion 512 .

(3-7-3) Moving Ball The moving ball 570 is spherical, and as described above, is movably placed on the base portion BP3 of the moving ball placement member BP. The moving ball 570 moves in the tilt direction between adjacent guide portions BP3a. When the kettle body 200 is upright, the moving ball 570 is fitted into the moving ball receiving portion 511 of the upper surface member 510 when the moving ball placement member BP of the locking mechanism 550 moves upward (see FIGS. 10 and 14).

(3-8) Sealing Member Sealing member 590 is a circular member made of an elastic material such as rubber or elastomer, and is attached to the outer periphery of the lower surface of bottom wall portion 522 of bottom plate member 520 as shown in Figures 3 to 5. Sealing member 590 serves to close the gap between liquid container 320 and bottom plate member 520 (in other words, to keep liquid container 320 and bottom plate member 520 tightly sealed) when lid unit 500 is attached to main body unit 300 as shown in Figures 3 to 5.

2. Power supply stand The power supply stand 600 serves as a power supply unit that supplies electricity to the electric kettle 100 and also serves as a base for the electric kettle 100. As shown in Figs. 1 and 3, the power supply stand 600 mainly comprises a power switch (not shown), a power cord 601, a power plug (not shown), and a connection terminal 602 that is electrically connected to the heater unit 340. The power switch is a switch for switching the connection state between the power supply terminal 342 of the heater unit 340 and the connection terminal 602. When the power switch is turned on, the heater unit 340 is electrically connected to the power supply stand 600. As a result, electricity is supplied to the heater unit 340, and the liquid in the liquid container 320 is heated. The power supply stand 600 can have the same configuration as a power supply stand for a conventionally known electric kettle.

<Operation to release the state in which the lid unit is locked to the main body unit in the electric kettle according to the embodiment of the present invention and 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 to the main unit 300 when the lid unit 500 is attached to the main unit 300. The user can release the state in which the lid unit 500 is locked to the main unit 300 (hereinafter referred to as the "locked state") by operating the locking mechanism 550 via the operating lever 560 (hereinafter referred to as the "unlocking operation"). The operation 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 Figures 4 and 5. 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. At this time, the torsion spring TS biases the claw portion RL2 of the locking lever RL of the locking mechanism LM in a direction that causes the claw portion RL2 of the locking lever RL of the locking mechanism LM to be locked to the claw receiving portion 352 of the discharge port forming portion 350. 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 outward to the left and right. In addition, the coil spring CS2 biases the moving ball placement member BP of the locking mechanism 550 and the lever stopper LS of the locking mechanism 550 downward. At this time, the convex fitting portion LS5 of the lever stopper LS of the locking mechanism 550 is fitted into the concave fitting portion RL1a of the locking lever RL of the locking mechanism LM. This prevents the locking lever RL of the locking mechanism LM from rotating around the axis AX (i.e., locked state). In addition, in the locked state, the height position of the operating lever 560 and the height position of the open/close button 530 are approximately the same.

Next, the unlocking operation will be described with reference to Figures 10 and 11. 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 the main unit 300 with the other hand. At this time, in conjunction with the movement of the operating lever 560, the moving ball mounting 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 in the center of the base part BP3 of the moving ball mounting member BP of the locking mechanism 550 in a plan view is pushed into the center 511a of the moving ball receiving part 511 of the upper surface member 510, and the user cannot lift only the operating lever 560, the moving ball mounting member BP of the locking mechanism 550, and the lever stopper LS of the locking mechanism 550 upward any further. This operation also 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 lever RL of the locking mechanism LM becomes rotatable about the axis AX, and the locked state is released. Furthermore, when performing the unlocking operation, even if the user lifts the operating lever 560 upward without holding the main unit 300 with the other hand, the main unit 300 cannot be lifted upward. This is because the force of the coil spring CS2 is adjusted so that the force required for the unlocking operation, i.e., the force required to lift the movable ball mounting member BP of the locking mechanism 550 and the lever stopper LS of the locking mechanism 550 upward against the force of the coil spring CS2, is smaller than the force required to lift the main unit 300. Note that if there is liquid in the liquid container 320, its weight will be even heavier, resulting in a similar result. Also, 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 unlocking operation, the user hooks his/her finger on the flange 562 of the operating lever 560 and further lifts the operating lever 560 upward, thereby lifting the entire lid unit 500 upward. At this time, the claw portion RL2 of the locking lever RL of the locking mechanism LM abuts against the upper end of the claw receiving portion 352 of the discharge port forming portion 350, and the locking lever RL of the locking mechanism LM is lifted upward and rotates against the biasing force of the torsion spring TS around the axis AX, so that the claw portion RL2 of the locking lever RL of the locking mechanism LM is finally positioned above the claw receiving portion 352 of the discharge port forming portion 350. This allows the user to remove the lid unit 500 from the main unit 300. When 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, it is again urged by the torsion spring TS so that its upper surface becomes approximately parallel to the plane perpendicular to the axis of the lid unit 500. Then, when the lid unit 500 is removed from the main unit 300 and the user releases his/her finger from the flange portion 562 of the operating lever 560, the moving ball placement member BP of the locking mechanism 550 and the lever stopper LS of the locking mechanism 550 are again urged downward by the coil spring CS2. Then, an engagement 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, when the lid unit 500 is completely removed from the main unit 300, it is in the same state as the lid unit 500 shown in FIG. 4 and FIG. 5 when only the lid unit 500 part shown in FIG. 4 and FIG. 5 is seen. Also, when the lid unit 500 is removed from the main unit 300, even if the user lifts the entire lid unit 500 upward without holding the main unit 300 with the other hand, the main unit 300 cannot be lifted upward. This is because the biasing force of the torsion spring TS is adjusted so that the force required to lift the locking lever RL of the locking mechanism LM upward while abutting the upper end of the claw receiving part 352 of the discharge port forming part 350 and rotate it against the biasing force of the torsion spring TS around the axis AX is smaller than the force required to lift the main unit 300. Note that if the liquid container 320 contains liquid, its weight becomes even heavier, resulting in the same result.

<Operation for locking the electric kettle according to the embodiment of the present invention>
Here, the operation of attaching the lid unit 500 removed from the main unit 300 back to the main unit 300 and locking the lid unit 500 to the main unit 300 (operation to put into a locked state) will be described with reference to Figures 12 and 13. First, the user pushes in 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 in the lid unit 500 until the claw portion RL2 of the locking lever RL of the locking mechanism LM reaches the lower side of the claw 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, whereby the lever stopper LS of the locking mechanism 550, the locking lever RL of the locking mechanism LM, and the bearing portion 580 slide inward against the biasing force of the 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 of the claw receiving portion 352 of the discharge port forming portion 350, 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. In this state, a locked state that prevents the claw portion RL2 of the locking lever RL of the locking mechanism LM from rotating is maintained.

<Prevention of unlocking operation when the electric kettle according to the embodiment of the present invention is tilted>
If the unlocking operation is possible when the kettle body 200 is tilted, there is a risk that the lid unit 500 will be detached from the body unit 300 and the liquid in the liquid container 320 will spill out. For this reason, 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. Hereinafter, the unlocking prevention structure RP that prevents the unlocking operation when the kettle body 200 is tilted will be described with reference to Figs. 14 and 15. Note that Figs. 14 and 15 show a state in which the kettle body 200 is tilted to the left. First, when the kettle body 200 is tilted in the locked state, the moving ball 570 placed at the center of the base part BP3 of the moving ball placement member BP of the locking mechanism 550 in a plan view rolls on the base part BP3 of the moving ball placement member BP of the locking mechanism 550 in the tilting direction. At this time, the moving ball 570 rolls between the guide parts BP3a of the moving ball mounting member BP of the locking mechanism 550 formed in the tilting direction. When the operating lever 560 is lifted to perform the unlocking operation in this state, the moving ball 570 is pushed into the peripheral part 511b of the moving ball receiving part 511 of the upper surface member 510. In this case, unlike when the moving ball 570 is pushed into the center part 511a of the moving ball receiving part 511 of the upper surface member 510 (see FIGS. 10 and 11), the fitting state between the convex fitting part LS5 of the lever stopper LS of the locking mechanism 550 and the concave fitting part RL1a of the locking lever RL of the locking mechanism LM is not released. That is, the locking lever RL of the locking mechanism LM is prevented from rotating about the axis AX because 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. 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 discharge port forming portion 350 (i.e., the unlocking operation is prevented).

<Opening and closing state of the liquid path in the electric kettle according to the embodiment of the present invention>
Here, the open/close 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 teacup (when discharging liquid) will be described. First, when the on-off valve 540 is in a closed state (i.e., when the on-off button 530 is not pressed downward), the packing 543 of the on-off valve 540 is in a state of close contact with the lower surface of the bottom plate member 520 (see Figures 3 to 5). This closes the liquid path (i.e., the inside of the liquid container 320 is a generally closed space). Therefore, even if the kettle body 200 is tilted when the on-off valve 540 is in a closed state, liquid will not flow directly into the discharge path DP from between the on-off valve 540 and the lower surface of the bottom plate member 520. Therefore, if the kettle body 200 is accidentally tipped over, it is possible to suppress a large amount of liquid from leaking out of the spout 301. On the other hand, when the on-off valve 540 is in an open state (i.e., 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 upper part of the liquid container 320 is in an open state. This opens the liquid flow path. When the on-off button 530 is pressed downward once, the button locking mechanism (not shown) maintains the on-off button 530 in a pressed state, i.e., the liquid flow path in an open state. Then, the user can pour the liquid in the liquid container 320 into a container such as a cup or a teacup by tilting the kettle body 200 toward the spout 301 with the liquid flow path open. After that, when the user presses the on-off button 530 again, the pressed state of the on-off button 530 is released, and the on-off valve 540 and the on-off button 530 are returned upward by the urging force of the coil spring CS1. This causes the on-off valve 540 to close the liquid flow path again.

<Features of the electric kettle according to the embodiment of the present invention>
(1)
In the electric kettle 100 according to the embodiment of the present invention, the claw portion RL2 of the locking lever RL of the locking mechanism LM can rotate about the axis AX, and in the locked state, is biased by the torsion spring TS in a direction in which it is locked to the claw receiving portion 352 of the outlet forming portion 350 of the main unit 300. Therefore, in the electric kettle 100, in the locked state, the pressure between the claw receiving portion 352 of the outlet forming portion 350 and the claw portion RL2 of the locking lever RL of the locking mechanism LM can be increased as much as possible, the lid unit 500 can be stabilized as much as possible in the vertical direction, and the force required by the user to release the lock can be adjusted. In addition, in the electric kettle 100, the sealing property of the seal member 590 can be adjusted so that the sealing property is not impaired.

(2)
In the electric kettle 100 according to the embodiment of the present invention, in the locked state, the convex fitting portion LS5 of the lever stopper LS of the lock mechanism 550 and the concave fitting portion RL1a of the lock lever RL of the lock mechanism LM are fitted together, and the lock lever RL of the lock mechanism LM cannot rotate about the axis AX. Therefore, in the locked state, the electric kettle 100 can prevent the lock lever RL of the lock mechanism LM from accidentally rotating and releasing the locked state.

(3)
In the electric kettle 100 according to the embodiment of the present invention, the lever stopper LS of the locking mechanism 550 is biased downward by the coil spring CS2, so that 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. In the locked state, the upper surface of the claw portion RL2 of the locking lever RL of the locking mechanism LM abuts against the claw receiving portion 352 of the outlet forming portion 350. Therefore, in this electric kettle 100, the user can lift the operating lever 560 upward to release the lock, and then lift the operating lever 560 further upward to detach the lid unit 500 from the main body unit 300 as is.

<Modification>
(A)
In the electric kettle 100 according to the previous embodiment, the lever stopper LS of the locking mechanism 550 is formed with a convex fitting portion LS5, and the locking lever RL of the locking mechanism LM is formed with a concave fitting portion RL1a. However, a concave fitting portion may be formed in the lever stopper LS of the locking mechanism 550, and a convex fitting portion may be formed in the locking lever RL of the locking mechanism LM. In addition, in the locked state, the lever stopper LS of the locking mechanism 550 and the locking lever RL of the locking mechanism LM do not necessarily have to be fitted together, and the lever stopper LS of the locking mechanism 550 does not necessarily have to put the locking lever RL of the locking mechanism LM in a non-rotatable state.

(B)
In the electric kettle 100 according to the previous embodiment, when the operating lever 560 is lifted upward in the locked state, the locked state is released, and as a result, the locking lever RL of the locking mechanism LM is in a state in which it can rotate around the axis AX. However, when the operating lever 560 is lifted upward in the locked state and the locked state, the locked state is released, and as a result, the locking lever RL of the locking mechanism LM may be in a state in which it can slide toward the axis line side (i.e., inward direction) of the lid unit 500 (i.e., in a state in which it can be released from the lock). In this case, in the locked state, the locking lever RL of the locking mechanism LM is prevented from sliding toward the axis line side (i.e., inward direction) of the lid unit 500, and thus the unlocking operation is prevented when the kettle body 200 is tilted.

(C)
In the electric kettle 100 according to the previous embodiment, the locked state is released by lifting the operating lever 560 upward in the locked state. However, in the locked state, for example, a finger may be placed on the upper surface of the flange 562 of the operating lever 560, and the operating lever 560 may be pushed downward (i.e., the opposite side to the side where the lid unit 500 is detached from the main unit 300) to release the locked state. In this case, the lid unit 500 can be removed from the main unit 300 by pinching the opening/closing button 530 with the fingers and lifting the entire lid unit 500 upward with the operating lever 560 pushed in. Alternatively, a gripping portion fixed to the upper portion of the lid unit 500 is provided, and the lid unit 500 can be removed from the main unit 300 by gripping the gripping portion and lifting the entire lid unit 500 upward with the operating lever 560 pushed in.

(D)
In the electric kettle 100 according to the previous embodiment, the dial mechanism 403 for adjusting the temperature of the print heater 341 of the heater unit 340 is disposed at the rear of the main body connection part 402 of the handle unit 400. However, the dial mechanism 403 may be disposed in the power supply base 600.

(E)
In the electric kettle 100 according to the previous embodiment, a groove is formed on the underside of the flange 562 of the operating lever 560 of the lid unit 500. However, this groove does not have to be formed, and the role of preventing slipping may be fulfilled by attaching an anti-slip sticker or the like.

(F)
In the electric kettle 100 according to the previous embodiment, the guide portion BP3a is formed on the base portion BP3 of the moving ball mounting member BP of the locking mechanism 550 of the lid unit 500. However, the guide portion BP3a does not have to be formed.

(G)
In the electric kettle 100 according to the previous embodiment, the print heater 341 is used as the heat source, but the heat source is not particularly limited and may be a sheath heater or the like.

Note that each of the above modified examples may be applied individually, or multiple examples may be combined and applied.
