Is lifted up, and is opened after the opening of the lid 7, and FIG.
As shown in (2), all the openings 2a are open. Here, water is supplied into the container 2 of the main body 1.

Next, when the lid 7 is tilted in the closing direction, the inner lid 24 first descends toward the opening 2a of the container 2 and comes into contact with the opening 2a. At this time, since the inclined portion 3b of the upper case 3 is formed above the opening 2a, it slides down along the inclined portion 3b, and as shown in FIG. To be housed. When the lid 7 is further lowered, the shaft of the connecting member 32 is
4 slides along the third hole 30 of the seal member 29 provided on the seal member 4, closes the lid 7 behind the inner lid 24, is locked to the main body 1 by the latch device 16, and closes the lid 7. As shown in FIG. 1, the inner lid 24 is pressed by the opening 2 a of the container 2 to be in a close contact state, and leakage of hot water or steam to the outside is closed.

Next, a method of removing the inner cover 24 for cleaning the inner surface of the inner cover 24 when the inner surface of the inner cover 24 is contaminated with hot water or the like will be described. First, in the same manner as described above, the lid 7
Then, the inner lid 24 is opened, and the opening 2a of the container 2 is fully opened as shown in FIG. Then, when the inner lid 24 is pulled away by holding the lid 7, the inner lid 24 and the lid 7 are connected by the flexible connecting member 32. As shown in FIG. 6, the cover 7 and the inner cover 2
4 is separated.

After only the inner lid 24 has been cleaned with water or the like, the second locking portion 32b of the connecting member 32 is pushed into the third hole 30 of the sealing member 29 as shown in FIG. Then, the inner lid 24 is attached to the connecting member 32 again, so that the inner lid 24 is attached to the lid 7.

According to the embodiment, the cover 7 and the inner cover 24 below the cover 7 are connected, and the cover 7 and the inner cover 24 are connected by the connecting member 32. Since the opening 24 is opened, when the lid 7 is opened, the steam in the container 2 is hardly applied to a hand or the like, so that there is no discomfort and the handling is improved. Further, the connecting member 3 for connecting the lid 7 and the inner lid 24 is provided.
2 is made of a flexible material having good heat resistance and the inner lid 24 is detachably provided on the lid 7, so that the inner lid 24 can be easily attached and detached, and the cleanability of the inner lid 24 is significantly improved. .

As is apparent from the above description, the following effects can be obtained by the electric water heater according to the present invention.

A lid composed of an upper lid and a lower lid, an inner lid provided below the lid, and a hinge device for pivotally supporting the lid so that it can be opened and closed;
A latch device for locking the lid to the main body, an opening / closing lever for releasing the latch device, and the like are provided. The lower lid and the inner lid are connected by a connecting member so that the inner lid is opened later than the lid is opened. Therefore, when the lid is opened, the steam in the container is less likely to catch on the hands and the like, there is no discomfort, and the handleability is improved.

Further, the connecting member is formed in a substantially string shape, and its entire length is formed sufficiently longer than the thickness between the lower cover and the inner cover, and first and second locking portions are formed at both ends of the connecting member. The first locking portion is fixed to the lower lid, and the shaft of the connecting member is slidably penetrated through the inner lid so that the second locking portion is locked to the inner lid,
After the lid is opened by the length of the connecting member, the second locking portion is locked to the inner lid to open the inner lid. It is less likely to be disturbed, there is no discomfort, and the handling is improved.

Further, the connecting member is formed in a substantially string shape, and its entire length is formed sufficiently longer than the thickness between the lower cover and the inner cover, and first and second locking portions are formed at both ends of the connecting member. Of the lower lid and the inner lid are fitted into the first and second holes provided substantially at the center of the lower lid and the inner lid, and a retaining seat protruding in a flange shape with an interval from the first locking part is provided. The connecting member is fixed to the lower lid by the first locking portion and the retaining seat, and the shaft of the connecting member is slidably penetrated through the second hole of the inner lid so that the second locking portion is formed by the inner lid. And the spring member is interposed between the spring seat and the lower cover, and the spring seat is constantly urged toward the inner cover side by interposing a spring seat between the connecting members. The inner lid is urged toward the container by the urging force of the spring seat until the inner cover is opened by the length of the connecting member, and after the lid is opened by the length of the connecting member, the second locking portion is opened. Second because the inner lid engaged with the hole has to be opened, and during the opening operation of the lid, difficult to apply such a steam hand in the vessel, there is no discomfort, the handling property is improved.

Further, since the inner lid is detachably attached to the lid by a connecting member, the inner lid can be attached and detached, and the cleaning property of the inner lid is significantly improved. Further, the connecting member is made of a flexible material, and an elastic sealing member is attached to a second hole provided in the inner lid to provide a third hole in the elastic sealing member.
