Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to an electric water heater for general household use.

BACKGROUND OF THE INVENTION A conventional electric water heater consists of a cylindrical container with a heater installed at the bottom, a cylindrical body that suspends and supports this container, and a cylindrical body located below the container. a hot water temperature control device provided in an internal space of the container, a container support plate provided on the lower surface of the container, and a substantially disc-shaped cover that covers a lower end opening of the container, the substantially disc-shaped cover is fixed to the container support plate by pulling the container downward and fixing the container, and rotatably attaches a substantially disc-shaped rotary stand holder located below the substantially disc-shaped cover to the cover; The lead wires of the heater and hot water temperature control device extended from the space were connected from below to a terminal block mounted on the rotary table which was fixed to the rotary table holder.

Problems to be Solved by the Invention The rotation angle of the rotary table in the above-mentioned conventional electric water heater is approximately 180 degrees in order to avoid twisting or other stress on the internal wiring, that is, the lead wires of the heater and hot water temperature control device. Therefore, for example, if you try to rotate this rotary table more than 180 degrees, you will not be able to do so.
Therefore, it was not very convenient in terms of usability.

The object of the present invention is to provide an electric water heater that solves these problems.

Means for Solving the Problems In order to solve the above problems, the present invention provides a plurality of conductive ring plates arranged concentrically from the center on the lower surface of a substantially disc-shaped cover that covers the lower end opening of the vessel, and A turntable holder having a conductive brush that makes electrical connection by slidingly contacting the conductive ring plate is rotatably extended to the cover, and lead wires led out from the heater or hot water temperature control device are connected to the conductive ring plate. The lead wire led out from the brush terminal of the conductive brush is connected to the terminal plate of the terminal block attached near the outer periphery of the rotary base holder and to which the terminal bar is fixed, and the lead wire is connected to the terminal plate of the terminal block to which the terminal bar is fixed. The lead wires and terminal board are covered with a rotary table that is attached from below.

Effect According to the above structure, the conductive brush of the rotary table holder is slidably contacted with the conductive ring plate of the cover fixed to the lower end opening of the container, so that it can be attached to the rotary table holder. The rotary table can rotate a full 360 degrees, and as a result, the electric water heater can be freely rotated from the right or left, which is very convenient for the user.

EXAMPLE Hereinafter, an example of the present invention will be described based on the accompanying drawings.

In FIGS. 1 and 2, reference numeral 1 denotes a cylindrical container made of a thin plate of stainless steel or the like, and this container 1 is suspended and supported within a container 2 which is also cylindrical. In addition, a step-like protrusion is formed concentrically at the bottom of the container 1, and a flat donut-shaped heater 3 is mounted in the middle of the protrusion using a presser metal fitting 3a, and near the outer periphery of the presser metal fitting 3a. A plurality of U-shaped container support plates 4 are placed and attached to the outer surface of the bottom of the container 1. Reference numeral 6 denotes a substantially disk-shaped cover that covers the lower end opening of the container body 2, and by fixing this cover 6 to the container support plate 4 with screws 6, the container 1 can be pulled downward and fixed. There is. Further, a hot water temperature control device 8 is disposed in a space 7 approximately in the center between the cover 5 and the bottom of the container 1. Further, on the lower surface near the outer periphery of the cover 6, a plurality of protrusions 9 having spherical tips are provided so as to protrude downward. The groove 1o is provided on the upper surface of the rotary table holder 13, and the rotary table holder 11 is rotatably attached to the cover 6 by screws 12.

A plurality of conductive ring plates 13 are provided on the lower surface of the cover 6 in a concentric manner and located around the outer periphery of the screw 12. A connecting portion 14 located at is provided. On the other hand, the same number of conductive brushes 16 as the number of conductive ring plates 13 are provided on the upper surface of the turntable holder 11, which have contacts that slide into electrical connection with the conductive ring plate 13.

A conductive brush 15 comes into contact with the conductive ring plate 13 via a contact point with a constant force. Further, a part of the conductive brush 16 penetrates through the rotary table holder 11 and is inserted into the rotary table holder 11.
A brush terminal 16 located on the lower surface is provided.

In addition, a projection 17 is integrally formed on a part of the lower surface of the rotary table holder 11 so as to protrude downward, and a terminal block 20 is fitted into this projection 17. It is equipped with a terminal bar 18 facing toward the inside and a terminal plate 19 located inward, and the terminal bar 18 and the terminal plate 19 are electrically coupled.

The lead wires 21 led out from the heater 3 and the hot water temperature control device 8 are connected to the conductive ring plate 13. A lead wire 22 connected to the connecting portion 14 and led out from the brush terminal 16 is connected to the terminal plate 19 of the terminal block 20.

After completing the connection of the lead wires 22 in this way, by fixing the substantially dish-shaped rotary table 23 to the rotary table holder 11 from below with screws 24, the lead wires can be connected to the rotary table 23.
2, the terminal plate 19, and the brush terminal 16.

Furthermore, holes 26 and 26 are provided in the rotary table holder 11 and the rotary table 23, respectively, located directly below the screw 6, and
Rubber legs 2 are press-fitted into the holes 26 of the rotary table 23.

As is clear from the above structure, in one embodiment of the present invention, the rotary table holder 11 is stacked on the cover 5 from below and is rotatably attached with screws 12. On the other hand, a terminal block 20 is similarly attached to the protrusion 17 of the rotary table holder 11 from below, and a lead wire 22 is used to connect the brush terminal 16 and the terminal plate 19. Next, the rotary table 23 is fitted into the rotary table holder 11, and both are fixed with screws 24. In this way, the rotating part is integrated into a unit.

Here, the lead wire 21 on the container body 2 side, which has been assembled in advance, is connected to the connection part 14 of the cover 6, and the unitized rotating part is connected to the container support plate 4 with the screw 6.
The entire water heater is integrated by fixing it to the rotary table 23, and then the hole 26 of the rotary table 23 is sealed with the rubber leg 27, thereby preventing water or dirt from entering the inside, and the assembly is completed. .

In the above embodiment, a plurality of protrusions 9 are provided on the lower surface near the outer periphery of the substantially disc-shaped cover 6, and the ring-shaped groove 1o that fits with the protrusions 9 is rotated in the substantially disc-shaped manner. Although the explanation has been given on the groove provided on the upper surface of the pedestal 11, on the contrary, a ring-shaped groove is provided on the lower surface of the substantially disc-shaped cover 6.
Even if a plurality of protrusions are provided on the upper surface of the substantially disk-shaped rotary table holder 11, the same effects as in the above-mentioned embodiment can be obtained.

Effects of the Invention As is clear from the description of the above embodiments, according to the present invention,
The conductive brush on the rotary table holder is made to freely rotate and slide into contact with the conductive ring plate of the cover fixed to the lower end opening of the device, so the rotary table attached to the rotary table holder can rotate all 380 degrees. The electric water heater can be rotated, and as a result, the electric water heater can be freely rotated from the right or the left, making it possible to provide an electric water heater that is very convenient for the user.
