The lock lever 99 turned upside down is put on the canopy 98 turned upside down, the guide groove 99d of the lock lever 99 is aligned with the guide rail 98d facing the canopy 98, and the lock lever 99 is moved from the inside to the outside. The guide groove 99d of the lock lever 99 is completely fitted into the opposing guide rail 98d of the canopy 98. Then, the finger contact recess 99a on the outer surface of the lock lever 99 reaches a position where it closes the lock lever opening 98c of the canopy 98 and stops. The other lock lever 99 is similarly fitted to the opposite side. Then, since the protrusion 99e for stopping the spring of the lock lever 99 is located at the opposite position, the spring 100 is attached between the protrusions 99e in the form shown in FIG.

  When the spring 100 is attached between the protrusions 99e, the lock levers 99 are pushed outward by the springs 100, and the finger rests 99a on the outer surfaces of the lock levers 99 are for the lock lever of the canopy 98. It reaches a position where it closes the opening 98c and stops. In this way, the canopy unit is completed.

  Thereafter, the canopy unit is attached to the above-described inner plug unit. The attachment is performed as follows. Place the inner plug unit, and place the canopy unit above the inner plug unit in the longitudinal direction of the inner plug unit. In that case, for example, a thumb and a middle finger are applied to the finger contact recess 99a of the lock lever 99, a force is applied in a direction in which both fingers approach, the lock lever 99 is pressed, and the locking claw 99b is retracted inward.

  Next, the canopy unit is pushed into the inner plug unit. After pushing in completely, release the finger from the lock lever 99. Then, the locking claw 99b is fitted into a locking claw fitting hole 79 provided on the left and right sides of the inner plug 71, and the tip of the locking claw 99b is outward from the locking claw fitting hole 79 of a predetermined length. Stick out. The lever 96 is in contact with the upper end of the notch 98b by the action of the lever spring 97, and can be pushed downward by the height of the notch 98b. Further, the four screw holes 76a of the inner plug 71 and the four screw holes (not shown) provided in the canopy 98 are substantially in a straight line.

  Thereafter, the assembled canopy unit and the inner plug unit are reversed, the screws b3 are inserted into the four screw holes 76a of the inner plug 71, and the canopy unit and the inner plug unit are integrally attached. Then, the plug main body 70 is completed by attaching the annular packing 89 to the outer peripheral portion of the inner plug 71.

  The plug body 70 is attached to the shoulder member 40 as follows. The plug body 70 is placed above the shoulder member 40 in accordance with the front-rear direction of the shoulder member 40. In that case, for example, a thumb and a middle finger are applied to the finger contact recess 99a of the lock lever 99, a force is applied in a direction in which both fingers approach, the lock lever 99 is pressed, and the locking claw 99b is retracted inward.

  Next, the plug body 70 is pushed into the shoulder member 40. After pushing in completely, release the finger from the lock lever 99. Then, the locking claw 99 b is fitted into the claw fitting holes 48 provided on the left and right sides of the shoulder member 40, and the plug body 70 is attached to the shoulder member 40. In this case, the annular packing 89 provided on the outer peripheral portion of the inner plug 71 abuts on the inner peripheral surface of the cylindrical body 43 of the shoulder member 40 to prevent the hot water from flowing out from this location. Further, the distal end portion 84b of the cylindrical packing 84 projecting outward from the valve chamber 81 comes into contact with the wall surface where the hole 47a of the recess 46 of the shoulder member 40 is opened so as to surround the hole 47a. Is communicated with the steam pipe 64 while being shielded from the outside. When removing the plug main body 70, the reverse operation, that is, the engagement between the locking claw 99b and the claw fitting hole 48 is released and the plug main body 70 is lifted and removed.

  In the state where the plug body 70 is attached to the shoulder member 40, the pouring port 86 is closed by the valve member 90 with respect to the inside of the inner container 20, but the steam port 85 is connected to the inside of the inner container 20 through the hollow chamber 77. As shown in FIG. 3, the steam generated in the inner container 20 flows out of the spout 44 via the white spout 44 and the white spout 44. 2, 3, 4, and sent to the temperature sensing member 34.

  During pouring, the lever 96 is pushed down, so that the valve member 90 is pushed down, and the pouring port 86 opens into the inner container 20. Therefore, as shown in FIG. 4, hot water is poured from the pouring spout 44 as indicated by the black arrows 7 and 8.

  When the electric kettle 10 falls to the front side, an annular packing 89 is provided on the outer periphery of the inner plug 71, and the steam port 85 is provided in the vicinity of the handle 68 on the rear side from the valve member 90. Hot water does not flow out from the outer periphery, and the steam port 85 is positioned above the surface of the hot water (when water is filled up to the full water position M shown in FIG. 1), so there is almost no outflow from the steam port 85.

  When the electric kettle 10 falls backward, the steam port 85 is located in the hot water and the hot water flows into the valve chamber 81 from the hollow chamber 77, but the water stop ball valve 82 in the valve chamber 81 is immediately cylindrical. It reaches the rear end portion 84c of the packing 84, contacts the rear end portion 84c, and closes the steam passage. In this case, the water stop ball valve 82 can be easily moved to the cylindrical packing 84 side by the inclined bottom wall 81a and the inclined wall 88e of the inner plug cover 88. Therefore, the outflow of hot water is greatly reduced compared to the conventional one even when it falls to the rear side.

  The present invention is not limited to the configuration of the above-described embodiment, and can be appropriately changed in design without departing from the gist of the invention.
