Abstract

PURPOSE:To improve assembling property, to maintain the quality of external appearance when an equipment is hung up and to reduce danger that water is invaded into an internal part by mounting a rotary stand to the boss part of a cover by a screw in an energized condition to the cover side with utilizing the material elasticity of the rotary stand itself. CONSTITUTION:A sliding groove 23 is formed on a lower surface near the outer circumference of a cover 19 and a boss 24 is formed in a center. Plural projections 25 to correspond to the sliding groove 23 of the cover 19 are mounted near the outer circumference and a deep tray-shaped rotary stand 27 to have a hole 26, which corresponds to the boss 24, are mounted in the center to the cover 19 freely rotatably by a screw 37. Then, the whole rotary stand 27 is energized by the material elasticity of the rotary stand 27 itself in the cover 19 side without using a spring, etc. Accordingly, when the equipment is hung up, an interval (c) between the outer circumferential part of the rotary stand 27 and the outer circumferential part of the cover 19 is not increased but suitably maintained. Then, the rotary force of the rotary stand 27 is suitable maintained as well. Since the energization of the rotary stand 27 in the cover 19 side is realized by the material elasticity of the rotary stand 27 itself, it is not necessary to use the parts such as the spring, etc., and the number of the parts can be decreased.

Further, the rotary table holder 6 and the rotary table 7 coupled to the lower part thereof constitute a rotation function section, and this rotation function section is rotatably attached to the cover 4 by a support frame 8. A sliding part receiving part 9 corresponding to the sliding part 6 of the cover 4 is formed near the outer periphery of the rotary table receiving part 6. As shown in the figure, a gap a is provided between the support frame 8 and the rotary table holder 6 to enable smooth rotation. In addition, to assemble the parts, first, with the container body 1 upside down from the figure, attach the rotary stand holder 9, and then attach the terminal plate 10.
and a terminal block 12 having a terminal bar 11 is attached and connected,
After that, the support frame 8 is fixed to the cover 4 with screws, etc., and the rotating table 7
is fixed to the rotating table holder 6 with screws or the like.

Problems to be solved by the invention In such a configuration, in order to perform the rotation function, 3.
-7 The rotary table 7, the rotary table holder 6, and the support frame 8 are required, which requires a large number of parts and is complicated to assemble. A gap a is provided between the rotary table holder 6 and the support frame 8 in order to allow this. However, as a result, when the container is lifted, the gap between the outer circumference of the container (-4) and the rotary table 7 increases, which impairs the appearance quality and furthermore, there is a risk of water droplets entering the interior. However, there was a problem in that the possibility of malfunction of the control device inside the vessel also increased.

The present invention improves ease of assembly by reducing the number of component parts and simplifying the structure, maintains the appearance quality when lifting the container, and has a rotary stand-equipped electric device that reduces the risk of water intrusion into the interior. The purpose is to provide water heaters.

Means for Solving the Problems In order to solve the objects, the present invention comprises a bottomed cylindrical container which 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 that covers the lower opening of the container and is attached to the container via the container mounting bracket; and a cover that covers the lower surface of the cover and has a hole in the center that corresponds to the boss. The rotary table is composed of a substantially deep dish-shaped rotary table having a sliding receiving part corresponding to the sliding part of the cover near the outer periphery, and this rotary table is biased toward the cover side by using the material elasticity of the rotary table itself. This is an electric water heater with a rotary stand that is rotatably attached to the post section of the cover with screws.

In the above structure, the present invention has a rotating function using only the rotary table and screws, so the number of parts is small, so assembly is easy, and the dimensional accuracy of parts does not matter even if they are thicker than conventional products. The stand is rotatably attached to the cover side under pressure due to the elasticity of the material, so when lifting the vessel,
There is no increase in the outer periphery gap between the cover and the rotary table, the appearance quality can be kept high, and there is no increase in the chances of water droplets entering, so there is no adverse effect on the internal control circuit.

Example Hereinafter, one embodiment of the present invention will be explained based on the drawings. I will explain.

In FIG. 1, a bottomed cylindrical container 16 made of a thin plate of stainless steel or the like is suspended and supported within a cylindrical container body 16. As shown in FIG. A heater 17 is attached to the back side of the bottom surface of the container 16, and a container mounting fitting 18 is further fixed. a cover 19 that covers the lower opening of the vessel body 16;
A ring-shaped holding plate 20 is fixed to the container mounting bracket 18 with screws 21 on the lower surface of the container 16, and the container 16 is pulled downward and fixed therein. A hot water temperature control device 22 in the container 16 is arranged in a space formed by the container 16 and the cover 19. A sliding groove 2 is provided on the lower surface near the outer periphery of the cover 19.
3, and a post 24 is formed downward in the center.

A plurality of protrusions 26 corresponding to the sliding grooves 23 of the cover 19 are provided near the outer periphery, and a hole 2 corresponding to the post 24 is provided in the center.
A deep dish-shaped rotary table 27 having a rotary plate 6 is rotatably attached to the cover 19 by screws 37. In this installation, the vicinity of the center hole 26 of the turntable 27 is deformed to the cover 19 side by an appropriate amount by tightening the screw 37, and therefore the outer body of the turntable 27 is attached to the cover 19.
It is biased by the elasticity of the material of the conversion table 27 itself without using a spring or the like on the side.

Therefore, when lifting the vessel, the outer periphery of the rotating table 27 and the cover 1
The gap C at the outer periphery of No. 9 is maintained properly without increasing,
In addition, the rotational force of the rotary table 27 is maintained appropriately, and the biasing of the rotary table 27 toward the cover 19 is realized by the elasticity of the material of the rotary table 27 itself, so there is no need to use parts such as springs. , the number of parts can be reduced.

On the other hand, a terminal block 28 is temporarily fixed to a portion near the outer periphery of the rotary table 27 with a claw, and then fixed with a screw 29. The terminal block 28 has a terminal bar 29 on the outside of the container body 16 and a terminal plate 30 on the inside.
are electrically coupled.

In addition, a plurality of lead wires 31 coming out from the hot water temperature control device 22
is taken out downward from a through hole 33 provided in a part of the disk portion 32 of the cover 19, and is connected to the terminal plate 3o by a connector 34 via a lead wire 36 with screws 7 and 36. Connector 34 is covered by cover 1
9 with a claw or the like, and the lead wire 36 is bent when the rotary table 2 is rotated.

Effects of the Invention As is clear from the description of the embodiments above, the present invention provides a rotation function using only the rotary table and screws, and uses the elasticity of the material of the rotary table itself to rotate the lower surface of the vessel without using a spring. Since it is attached to the cover side so that it can rotate freely in a biased state, the number of component parts is greatly reduced and the structure is simple, which improves ease of assembly and reduces the gap between the outer periphery of the rotary table and the cover when lifting the instrument. Since the water does not increase or change, it is possible to maintain a high-quality appearance and to greatly reduce the chance of water intrusion into the interior of the vessel.
