Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to an electric water heater with a rotary stand that is easy to use and operate.

BACKGROUND OF THE INVENTION A conventional electric water heater of this type has a configuration as shown in FIG.

As shown in the figure, a cover 4 covering the bottom opening of the container 1 is attached to the container mounting bracket 3 attached to the bottom surface of the container 2 inside the container 1, and a sliding groove 5 is provided near the outer periphery of the cover 4. A boss 6 is provided in the center. Further, the substantially deep dish-shaped rotary table 7 has protrusions 8 corresponding to the sliding grooves 6 of the cover 4 and holes 9 corresponding to the bosses 6 formed near its outer periphery, and is rotatably attached to the cover 4. ing.

On the other hand, a window 10 is formed in a part of the outer circumferential wall of the rotary table 7, and a terminal block 11 is fixed so as to face the outside from this window 1o, and a terminal block 11 is fixed so as to face the outside from the window 1o. A hot water temperature control device 12 provided in the space and the terminal block 11 are electrically connected by a lead wire 13.
The problem to be solved by the invention is that the cover 4 is fixed to the cover 4 by using a clamping screw or the like between a claw part 14 having a corrugated uneven part on the surface and a separate fixing member 15. In a conventional electric water heater with a rotary table, the lead wire 13 connecting the hot water temperature control device 12 and the terminal block 11 is fixed to the cover 4 using a claw portion 14 having a corrugated surface and a separate fixing device. Since the mounting member 16 is fixed with a clamping screw or the like, there are problems in that the number of components increases and the assembly becomes complicated.

The present invention solves the above-mentioned problems, and aims to provide an electric water heater with a turntable function that has a small number of component parts and is easy to assemble.Means for Solving the ProblemsThe present invention In order to achieve the above purpose, the first means is:
A bottomed cylindrical container is suspended and supported in a substantially cylindrical container body, and has a container mounting bracket on the lower surface, a boss part in the center, and a sliding part near the outer periphery, and the lower surface of the container is A cover attached to the container via the container mounting bracket so as to cover the opening, a hot water temperature control device provided in the space between the cover and the container, and a boss portion in the center that covers the lower surface of the cover. a hole corresponding to the cover, and a sliding receiving part corresponding to the sliding part of the cover near the outer periphery, a window part in a part of the outer peripheral wall, and the cover is rotatably attached to the cover with a screw. A substantially deep-dish-shaped rotary table, a terminal block facing the outside through a window of the rotary table, and a lead wire that penetrates a part of the cover and electrically connects the terminal block and the hot water temperature control device. A fixing part for the lead wire is formed on the cover, and the fixing part for the lead wire is attached to the groove part of the cover with a part of the lead wire in a meandering state, and the friction force between the wall of the cover and the lead wire is reduced. The series lead wire is fixed to the holder.

Further, the second means is such that a convex portion is formed in a part of the wall of the groove of the lead wire fixing portion of the first means in the direction in which the lead wire is removed.

Effects of the present invention With the above structure, in the first means, by inserting the lead wire into the groove of the lead wire fixing portion formed in the cover, a part of the lead wire becomes meandering, and the groove and the lead wire Since the lead wire is held by friction with the lead wire and not by a separate member, the number of parts is small and it is easy to assemble.

In addition, in the second means, since the lead wire fixing part of the first means is formed with a protrusion in the lead wire detachment direction, the holding force due to the friction between the fixing part and the lead wire is further increased by the protrusion. Since this method requires a force to overcome this, it is possible to secure even stronger holding power for the lead wire with the same number of parts as the first method.

EXAMPLE Hereinafter, an example of the present invention will be described with reference to FIGS. 1 to 4.

As shown in FIG. 23 is attached, and further a container mounting bracket 24 is fixed to the lower surface. The bottom opening of the vessel body 22 is covered by a cover 25.
A ring-shaped holding plate 26 is disposed on the lower surface of this cover 26, and this holding plate 26 and the cover 26
and are fixed to the container fitting 24 with screws, thereby fixing the container 21 so as to be drawn downward. Further, a temperature control device 2 is provided in a space formed by the container 21 and the cover 25 to control the temperature inside the container 21.
7 is placed. A sliding groove 28 is formed on the lower surface near the outer periphery of the cover 25, and a boss portion 29 is integrally formed in the center so as to project downward. The substantially deep dish-shaped rotary table 30 has a plurality of protrusions 31 formed near its outer periphery corresponding to the sliding grooves 28 of the cover 25, and a hole 32 corresponding to the boss portion 29 formed in the center. The turntable 3o is rotatably mounted on the boss portion 29 of the cover 25.

Further, a window portion 33 is formed in a part of the outer peripheral wall of the rotary table 3o, and a terminal block 34 is mounted so as to face the outside from this window portion 33. and are electrically coupled by two lead wires 35 passing through the cover 25, and the lead wires 35 are bent when the rotary table 3o rotates. A fixing portion 37 for the lead wire 35 is provided near the through hole 3e through which the lead wire 35 passes through the cover 25.
is formed. This fixing part 37 is connected to the two IJ-
On one side of the two adjacent walls 38, 39 of the three walls 38, 39, 40 corresponding to the wire 35, there is a wooden wall 41 facing almost perpendicular to the other wall, and a wall 41 slightly offset from this wall 41. A wall 42 is formed at the location where the two walls 41 . 42 are arranged in a staggered manner to hold the attached lead wires 36. Also,
The other adjacent walls 39 and 40 also hold the lead wire 35 in the same way as the two walls 41, 42 described above.

In the second configuration, when the lead wire 35 is attached to the fixed part 37, a part of the lead wire 36 becomes meandering as shown in the figure, and due to the frictional force between the fixed part 37 and the lead wire 36, it moves in the direction B. Holding force in the C direction is ensured.

Therefore, 350 lead wires can be easily set without using any separate members.

As described above, according to the first embodiment of the present invention, the lead wire 3
Since a part of the lead wire 5 can be attached to the fixing part 37 of the cover 26 in a meandering state and held by the frictional force with the wall, the lead wire 36 can be easily held without adding any separate parts.

Still, FIG. 4 shows a second embodiment, in which, like the first embodiment, the lead wire fixing part 37 is formed by three walls 38, 39, 40.
Staggered wall 41.42 between two adjacent walls 38.39
Furthermore, after the lead wire 35 is attached, a convex portion 45 is provided at one or more locations on the wall to provide resistance in the detachment direction (direction C). According to the second embodiment of the present invention, the effect is not only due to the frictional force as in the first embodiment, but also due to the
The mechanical holding force provided by 6 is added to securely hold the lead wire 3.
Effects of the Invention As is clear from the above embodiments, according to the present invention, in the first embodiment, a part of the lead wire is attached in a meandering state. The lead wires can be easily attached and held by friction with the staggered walls of the cover without adding any additional parts.

In addition to the first embodiment, the second embodiment has a protrusion in the direction in which the lead wire is removed, so the holding force for the lead wire requires a force to overcome the protrusion. It is possible to secure a holding force that is even greater than that of the first embodiment.
