Description

DETAILED DESCRIPTION OF THE INVENTION Industrial Field of the Invention The present invention relates to an electric water heater whose direction can be freely changed through a turntable.

2. Description of the Related Art Conventionally, in this type of electric water heater, a substantially circular ring-shaped base made of synthetic resin or the like is provided at the lower end of the exterior body, and the base is rotatably supported on the turntable. It was attached to the base by a back plate that closes the space (Actual Kosho 59-
(See Japanese Patent No. 40889).

However, according to the above configuration, the back plate must be necessarily attached and detached when the turntable is attached and detached. Therefore, the assemblability is poor when the turntable is replaced or inspected. In the case of internal inspection, when the back plate was removed, the turntable was also removed, which made the work troublesome and led to the loss of the turntable itself.

The present invention solves the above-mentioned conventional problems, and an object thereof is to provide an electric water heater that is easy to assemble and inspect.

Means for Solving the Problems In order to achieve the above object, the present invention provides a container for containing a liquid heated by a heater, an exterior body covering the container, and a bottom surface provided on the lower end of the exterior body. Is provided with a substantially circular ring-shaped base having a groove formed in the circumferential direction, a circular ring-shaped rotary base which is rotatably and detachably attached to the groove, and a back plate which closes a space portion of the substantially circular ring-shaped base. The outer diameter of the back plate is located inside the groove forming portion of the base, and is fixed to the base independently of the turntable.

Operation According to the above configuration of the present invention, not only the turntable but also the back plate can be independently attached and detached.

Embodiments Embodiments of the present invention will be described below with reference to the accompanying drawings.

In the figure, a heater 3 is fixed to the outer bottom surface of the container 1 via a fixture 2. In addition, the exterior body 4 that covers the container 1
Has a base 5 made of synthetic resin at the lower open end thereof. The base 5 has a substantially circular ring shape, and its inner space is closed by a back plate 6. A predetermined space 7 is set between the back plate 6 and the outer bottom surface of the container 1, and a temperature control device 8 is housed therein. Reference numeral 9 is an angle for fixing the container 1, the base 5 and the back plate 6 with screws 10. A groove 11 is recessed from the outer peripheral portion of the lower surface of the base 5, that is, from the outer peripheral portion of the back plate 6, where the outer peripheral edge of the back plate 6 is located. A plurality of claws 12 are integrally formed toward the standing wall surface 11b.

These claws 12 can be molded in two halves by providing a cut hole 17 that is difficult to form the top wall 11C of the groove 11.

13 is a ring-shaped rotary table, and a plurality of pawls are provided above the inner peripheral portion of the rotary table.
By engaging 14 with the claw 12 of the base 5,
A plurality of protrusions 15 are attached to the shaft 11 so as to be rotatable and detachable, and the tips of which are in contact with the top wall 11c of the groove 11 are formed. Six legs 16 are projected from the lower surface of the rotary table 13 located below the lower end of the base 5. Three of the six legs 16 are higher than the other legs, and normally have a three-point support structure.

In the above-mentioned configuration, the water heater is the protrusion 15 of the turntable 13.
It slips over and is turned around.

Here, since the turntable 13 and the back plate 6 are independently attached to the base 5, each can be independently attached and detached. Therefore, the rotating table 13 can be easily replaced, and the temperature control device 8 and the like with the back plate 6 opened can be easily checked.

As described above, according to the present invention, the circumferential groove is formed on the lower surface of the base provided at the lower end of the exterior body, and the rotary base is attached to the groove in a rotatable and detachable manner. By setting the outer diameter of the back plate that closes the space to a size that is located inside the groove forming part of the base, the back plate and the rotary base can be independently fixed to the base, which allows assembly. The workability can be greatly improved.

As a result, it is possible to quickly and easily carry out an internal inspection and exchange of the turntable, which is an excellent effect.
