Problems to be Solved by the Invention However, in such a configuration, the rotating table 7, the rotating table holder 6, and the support frame 8 are required in order to perform the rotation function, which increases the number of parts and makes assembly difficult. This was complicated, and required dimensional accuracy between the parts in order to achieve smooth rotation. Furthermore, in the above conventional configuration, a gap is provided between the rotary table holder 6 and the support frame 8 in order to rotate the container body 1 smoothly.
When the cover 4 and the turntable 7 are lifted up, the gap between the outer periphery of the cover 4 and the turntable 7 increases, which not only impairs the appearance quality but also increases the chances of water droplets entering the interior. Therefore, there is a problem that the possibility of malfunction of the control device inside the vessel 1 increases.

The present invention solves these problems by improving assembly efficiency, maintaining the appearance quality when lifting the container, and reducing the chance of water intrusion into the interior. The purpose of this invention is to provide an electric water heater with a stand.

Means for Solving the Problems In order to solve the above problems, the present invention provides a bottomed cylindrical container that is suspended and supported within a substantially cylindrical container body and has a container mounting bracket on the lower surface, and a boss in the center. a cover that has a sliding part near the outer periphery and is attached to the container body via the container mounting bracket so as to cover the bottom opening of the container body; a substantially deep dish-shaped rotary table having a hole corresponding to the boss portion and a sliding part receiver corresponding to the sliding part of the cover near the outer periphery, and the rotary table is always biased toward the cover side. In this state, it is rotatably attached to the boss portion with a screw.

Effect According to the above configuration, the rotary table is rotatably attached to the boss portion provided on the cover that covers the lower opening of the vessel body, and
Since the rotary function is achieved using only the rotary table and screws, the number of parts is reduced, and therefore assembly is extremely simple.

In addition, since the rotary table is rotatably attached to the cover while always being biased, the outer gap between the cover and the rotary table does not increase when the instrument is lifted, and as a result, the appearance quality is improved. Not only can high quality be maintained, but also there is less chance of water droplets penetrating into the interior, thereby eliminating any adverse effects on the internal control circuit.

Embodiment Hereinafter, one embodiment of the present invention will be described based on the accompanying drawings.

In FIGS. 1 and 2, a bottomed cylindrical container 16 made of a thin plate of stainless steel or the like is suspended and supported within a substantially cylindrical body 16, and the back side of the bottom of this container 16 is A heater 1 is attached to the container, and a container mounting bracket 18 is fixed to the lower surface. The lower opening of the container body 16 is covered by a cover 19, and a ring-shaped retaining plate 20 is disposed on the lower surface of the cover 19, and the retaining plate 20 and the cover 19 are connected by screws 21 to the container. Mounting bracket 1
8, the container 16 is pulled downward and fixed. Further, a hot water temperature control device 22 for controlling the temperature of hot water inside the container 16 is disposed in a space formed by the container 16 and the cover 19. Said cover 1
A sliding groove 23 is formed on the lower surface near the outer periphery of 9, and a boss portion 24 is integrally formed in the center so as to protrude downward. The substantially deep dish-shaped rotary table 27 has a plurality of protrusions 25 formed near its outer periphery corresponding to the sliding grooves 23 of the cover 19, and a hole 26 corresponding to the boss portion 24 formed in the center. , and this turntable 27 is connected to the cover 19.
The boss part 241C1 of the cover 1
It is rotatably mounted with a screw 39 in a state where it is always biased towards the 9 side. This prevents the rotary table 27 from falling off the cover 19, and the load of the electric water heater is also borne by the plurality of protrusions 26 via the sliding grooves 23. Further, since the rotary table 27 is always urged toward the cover 19 by the circular wave-shaped spring 28, the gap C between the rotary table 27 and the cover 19 increases when the container body 16 is lifted. This is no longer the case, and as a result, the gap C is maintained appropriately, and the rotational force of the rotary table 270 is also maintained appropriately.

On the other hand, a terminal block 29 is temporarily fixed to a portion near the outer periphery of the rotary table 27 with a claw, and then fixed with a screw 30. The terminal block 29 is provided with a terminal bar 31 on the outside and a terminal plate 32 on the inside, and the terminal bar 31 and the terminal plate 32 are electrically coupled.

Further, the plurality of IJ-wires 33 coming out of the hot water temperature control device 22 are taken out downwardly through a through hole 35 provided in a part of the disk portion 34 of the cover 19, and are connected to the lead wires 37 by a connector 36. It is connected to the terminal plate 32 via a screw 38. The connector 36 is fixed to the cover 19 with a claw or the like, and when the rotary table 27 rotates,
The lead wire 37 is to be bent.

Effects of the Invention As is clear from the description of the embodiments above, according to the present invention, the rotary table is rotatably attached to the boss portion provided on the cover that covers the lower opening of the vessel, and the rotary table and the screw are connected together. Since the rotary function is exerted by a chisel, the number of parts can be reduced, and as a result, the bottom of the tank can be simplified, making it possible to improve ease of assembly.

In addition, since the rotary table is rotatably attached to the cover while always being biased, the outer gap between the cover and the rotary table does not increase when the instrument is lifted, and as a result, the appearance quality is improved. Not only can high quality be maintained, but since there is less chance of water droplets entering the interior, it is possible to eliminate any adverse effects on the internal control circuit.
