Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to an electric water heater having a removable lid that opens and closes the opening of the container.

Conventional technology Conventional electric water heaters of this type include, for example,
As shown in Japanese Patent No. 57-64277, it had a structure as shown in FIG.

That is, the hinge stand 23 has an L-shaped groove in which an opening groove (not shown) and a locking groove (not shown) are connected to the rear side of the spout 22 placed on the upper end of the water heater main body 21. is provided so as to protrude outward from the side surface of the water heater main body 51, and a rotary shaft 25 fixedly mounted on the lid 24 for opening and closing the upper opening of the spout 22 is inserted through the opening groove of the hinge base 53 and engaged. A hinge was formed at the stop groove portion, and the lid 24 was engaged with this hinge so as to be openable and closable.

Problems to be Solved by the Invention However, with such a conventional configuration, when the lid 24 is opened and the user tries to transport the water heater by placing his hand on the lid 24 and the water heater body 21, the lid 24 easily comes off. However, there was a problem in that the electric water heater itself could be dropped, causing injuries such as burns.

This invention solves these problems,
The object of the present invention is to provide an electric water heater that can ensure safety during transportation of the water heater itself.

Means for Solving the Problems In order to solve the above problems, the present invention includes a spout that is placed on the water heater body and that locks the container;
A pair of walls integrally erected on the rear upper surface of the spout, a support shaft fixed to the wall, and a lid provided above the spout for opening and closing the opening of the container. It has a lever housed in the lid and a knob for operating the lever from outside the lid, and the lever is always biased by a spring to a position where it locks the support shaft. .

Effect According to the above configuration, the lever stored in the lid is
The support shaft fixed to the wall of the spout is constantly biased by a spring to the locking position, so even if the lid is pulled while it is open, it will not come off easily. , it is possible to provide an electric water heater with excellent safety.

Embodiment Hereinafter, an embodiment of the present invention will be described based on the accompanying drawings. In FIGS. 1 to 4, reference numeral 1 denotes a spout made of heat-resistant synthetic resin such as polypropylene resin, and this spout 1 is placed on the upper end of the water heater body 2 made of printed steel plate. A container 4 for holding water is secured to the inner step 1a via a packing 3. Further, a base 5 is provided at the lower end of the water heater main body 2, and the base 5 is screwed to the bottom surface of the container 4.

Reference numeral 6 denotes a lid for opening and closing the upper opening of the spout 1. This lid 6 is equipped with a pump mechanism (not shown) for pumping air into the inside, and inside the rear part there is a lid that follows the outer wall surface of the lid 6. A lever 7 formed into a shape is rotatably locked, and a knob 8 whose end surface projects outside the lid 6 is provided above the upper surface of the lever 7. Reference numeral 9 denotes a lower portion of the lid 6, and the lower portion 9 of the lid is integrally formed with a wall surface 9a facing the recess 7a provided near the lower end of the lever 7. Numeral 10 is a baffle provided between the lower lid 9 and the lever 7 that biases the end surface of the recess 7a of the lever 7 and the wall surface 9a of the lower lid 9 into close contact with each other. Reference numeral 11 denotes a pair of walls erected integrally on the rear upper surface of the spout 1. 12 is a support shaft fixed to a pair of walls 11, and this support shaft 12 fits into the recess 7 of the lever 7.
a and the wall surface 9a of the lower lid 9 to form a rotatable hinge.
are engaged so that they can be opened and closed.

13 is a handle rotatably engaged with the water heater body 2; 14 is a display board; 15 is a water level display window provided on the display board 14; This is a discharge port through which the hot water in the container 4 is discharged.

As is clear from the above configuration, in the embodiment of the present invention, the hinge of the lid 6 normally has a spring 10
Due to the biasing force, the recess 7a of the lever 7 and the wall surface 9a
Since the supporting shaft 12 fixed to the spout 1 is sandwiched between the and the spout 1, it is possible to hold the lid 6 and the water heater main body 2 with your hands while transporting the lid 6 with the lid 6 open.
remains engaged with the support shaft 12, so
There is no chance of it falling off, making it extremely safe.

Also, when removing the lid 6, as shown in Figure 2,
By pushing the knob 8 protruding outside of the lid 6 in the direction of arrow A, a space is created between the recess 7a of the lever 7 and the opposing wall surface 9a, so that the support shaft 12 can be attached and detached, and then By pulling up the entire lid 6 in the direction of arrow B, the lid 6 can be easily removed from the support shaft 12.

Furthermore, a lever 7, a spring 10, which constitutes a hinge,
The lower lid 9 and the pair of walls 11 that are erected behind the spout 1 and to which the support shaft 12 is fixed are all provided without protruding beyond the external line of the vessel, improving the appearance quality. Of course, it can be packed into a compact shape, and as a result, packaging costs can be reduced.

Further, as shown in FIG. 2, water droplets when the lid 6 is opened can be condensed into the container 4 from the outer peripheral end surface of the lid packing 17 provided on the outer periphery of the lower lid 9. There is no risk of water droplets leaking and getting the table etc. wet, making it very practical.

Effects of the Invention As described above, the present invention includes a lever housed in the lid and a knob for operating the lever from outside the lid, and the lever is always spring-loaded in a position where it locks the support shaft. Even if the lid is pulled while it is open, the lid will not come off easily, making it possible to provide an electric water heater with excellent safety. .
