Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a configuration for positioning a container and spout of an electric water heater.

Conventional structure and problems Conventionally, this type of electric water heater required the use of special metal fittings to position the spout and container, which made assembly work difficult and made it impossible to completely prevent misalignment. As a result, there were cases where the through hole in the transparent cover and the transparent tube of the water level gauge were misaligned, making it impossible to check the water level inside the container from the outside.

Purpose of the invention The present invention aims to provide an electric water heater that does not require special fittings when assembling the container and spout, reliably prevents misalignment, and allows the water level in the container to be checked from the outside. It is.

Structure of the invention In particular, the present invention provides a protruding pipe for attaching a water level gauge to the side wall of the container, a claw part having a stopper part and a non-return protrusion on the horizontal part of the spout, and a protruding pipe with a stopper part and a non-return protrusion. To provide an electric water heater in which the water level in the container can be reliably confirmed from the outside by preventing misalignment of the spout and the container by engaging them between the spout and the container to regulate the position of the spout and the container. be.

DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below with reference to the accompanying drawings. 1 is a body, on the upper end of which a spout 2 is placed, and on the lower end a base 3 is fixed. 4 is a lid pivotally supported at the rear of the spout 2; 5 is a bottomed cylindrical container housed in the body 1; a projecting tube 6 projecting outward is provided at the upper and lower side walls of the container 5; It is provided. 16 is a packing fastened to the spout 2 and the container 5. Reference numeral 7 designates a transparent tube, and its upper and lower ends are connected to the protruding tube 6 via a flexible connecting tube 8 made of silicone rubber or the like to constitute a water level gauge. A vertically long through hole 1a is formed in the body 1 to correspond to the transparent tube 7, and the amount of water in the container 5 can be seen from the outside through a transparent cover 9 that closes the hole 1a. 10 is a heating element wrapped around the lower part of the container 5. Reference numeral 11 denotes a container mounting bracket, which is fastened to the base 3 with screws. As shown in FIG. 2, the spout 2 has an opening 2a set to have approximately the same diameter so as to fit softly onto the body of the container 5, a horizontal portion 2b on which a flange 5a is placed, and a stopper on the back side of the horizontal portion 2b. A claw portion 15 consisting of a portion 15a, a check projection 15b, and a saddle portion 15c is provided.

After fitting the packing 16 and spout 2 into the container 5, the protrusion 6 is inserted into the mounting hole 5b by positioning the mounting hole 5b provided on the side wall of the container 5 away from the claw portion 15 of the spout 2. Fitting push nut 1
It is fixed at 2. After this, when the container 5 is rotated in the direction of arrow A as shown in FIG. Due to this action, the positions of the container 5 and spout 2 are regulated to be constant. At this time, the position of the protruding pipe 6 is set so as to match the transparent cover 9 provided on the body 1, and the saddle part 15c has a packing 16 between the flange 5a of the container 5 and the horizontal part 2b of the spout 2. The container 5 and spout 2 are set at a height that allows easy rotation.

In this way, the positioning of the spout 2 and the container 5 is performed by the protruding tube 6 to which the transparent tube 6 is directly attached, so that the transparent tube 7 and the vertically long through hole 1a, which were often seen in the past, are
There will be no discrepancies.

Furthermore, since the outer diameter of the container 5 and the inner diameter of the spout 2 into which it is inserted are approximately the same, when the container 5 is rotated after insertion so that the protruding tube 6 is held in the saddle portion 15c provided on the claw portion 15 of the spout 2, there is no rattling in the thrust direction during assembly work, and workability is extremely good.

Furthermore, this eliminates almost any damage to the inner surface of the spout 2 caused by the end face of the flange 5a of the container 5 due to vibrations during assembly work.

Effects of the invention As stated above, with this invention, the positioning of the spout and container required during assembly can be done economically without the use of special metal fittings, and it is also possible to achieve electrical It is possible to provide a water heater, and its practical value is extremely great.
