For this reason, the operation with the left hand is somewhat troublesome.

  In addition, since the shaft 7b is provided below the hot water supply lever 7 in the conventional hot water supply lever 7, the worst hot water supply lever when the user presses the rear side of the pressing portion 7a, for example, the upper surface in the vicinity of the shaft 7b. 7 The hot water switch below is not turned on.

  Moreover, since the shaft 7b of the conventional hot water supply lever 7 is provided below the hot water supply lever 7, when the user presses the pressing portion 7a, the rear end portion 7c of the hot water supply lever 7 moves up significantly. Thus, a large gap is generated between the shoulder member 2 and the appearance is deteriorated.

  A device shown in FIG. 13 has been proposed to improve the operability of the conventional example. The electric hot water storage container 11 shown in FIG. 13 is provided with an operation unit 14 having various switch buttons 15 and a display unit 16 on the upper surface of the nose unit 13 on the front side of the lid member 12, and the nose unit 13 below the operation unit 14 has a front side. A rectangular pocket portion 17 that is long in the left-right direction with the side opened is provided, and a hot water supply lever 18 that is long in the left-right direction for electrically driving the electric pump is disposed in the pocket portion 17.

  Most of the hot water supply lever 18 is housed in the pocket portion 17, and when it is moved down with a finger as shown by an arrow, an electric pump (not shown) is driven to supply hot water from the hot water supply port 19 (see, for example, Patent Document 2). ).

  By the way, in the conventional example shown in FIG. 13, the hot water supply lever 18 is housed in the pocket portion 17, and the operability and appearance from both the left and right sides are good, but the operation is performed by putting a finger in the pocket portion 17. It has a problem that it is slightly inferior and difficult to care for.

  Further, the conventional example shown in FIG. 13 has two front panel parts, two sliding pins as shafts, and two sliding pins for attaching the hot water supply lever 18 as shown in FIG. 7 parts of a single bearing member and a single reinforcing member are required, resulting in a problem that the production cost increases and the assembly takes time.

As shown in FIG. 1, the same arc surface as the side surface of the operation unit 50 and the lid member 22, that is, flush with the front surface 65 c is the same arc surface as the front surface of the nose portion 33, as shown in FIG. . Thus, since the hot water supply lever 65 has at least the upper surface 65a flush with the upper surface of the operation unit 50, the appearance of the hot water supply lever 65 is improved and the maintenance is simplified.

  In addition, although each surface of the hot water supply lever 65 demonstrated the same example as each surface of the nose part 33, it may be a little larger or smaller than it. For example, the width in the left-right direction of the hot water supply lever 65 may be greater than or equal to the width S in the left-right direction of the main body 56a of the microcomputer board 57 (see FIG. 9).

  When the hot water supply lever 65 is set in the recessed portion 61, as shown in FIG. 11, the position of the hot water supply switch 58a is in the vicinity of the hot water supply port 25 that does not overlap with the hot water supply port 25 in a plan view or a front view. It becomes near in the left-right direction. Therefore, an increase in the size of the three-layer structure of the hot water supply lever 65, the hot water supply switch 58a, and the hot water supply port 25 is prevented, and the hot water supply switch 58a is more reliably turned on regardless of which part of the hot water supply lever 65 is pressed. In other words, the hot water supply lever 65 moves like a seesaw and the adverse effect that the hot water supply switch does not turn on is eliminated.

  The invention of the present application is not limited to the configuration of the above embodiment, and it is needless to say that the design can be appropriately changed without departing from the gist of the invention.
