問１[0001]The present invention relates to cleaning of a bathwater heater using tap waterpressure and a cleaning tool.
[0002]

Conventionally, the bathwater heater is cleaned by such methods as removing

an attachment from a hot water port and then injecting pressurized water from a vinyl
hose into the bathwater heater or using commercially available carbonate chemicals.
[0003]

The above methods may have downsides as listed below.

(i) It is difficult to completely clean off sludge by injecting pressurized water; theremaining sludge may result in rapid accumulation of sludge when the bathwater
heater is used again.
(ii) Chemical cleaning is difficult to perform.
(iii) Chemical cleaning is expensive; the cost for performing a single chemical cleaning ishigh.
(iv) These cleaning methods may cause water pollution.
(v) For a bath using milky bathwater, in particular, the bathwater heater easily
becomes dirty, and these cleaning methods may not prevent the noise and sludge
coming out of a hot water port when bath water is reheated while bathing, which is very
unsanitary.
The present invention is made to solve these problems.
[0004]An aspect of the present invention is a bathwater heater cleaning tool

including a resin-made-stepped pipe (1), a nozzle (2), and a sponge cleaning tool (3)provided on the distal end of the nozzle (2). The bathwater heater cleaning tool is usedwith tap water having a certain pressure to clean the bathwater heater.

問２[0016]

FIG. 2 is a plan view of a type-1 jig 2a. FIG. 2 illustrates the positional

relationship between the type-1 jig 2a and a base plate 1a, a circular guide 8, and ajigsaw blade 10 for cutting, where the jigsaw 1 is not shown in the drawing.
[0017]

A diagonal slider 4 is held by two screw-equipped guiding blocks 7 on the front

face of the metal type-1 jig 2a. Fixing attachments 3 are provided at both ends on therear side of the type-1 jig 2a. The screw-equipped guiding blocks 7 selectively fix thediagonal slider 4 or allow the diagonal slider 4 to slide along a 45-degree line of whichangle to a side of a plate member is 45 degrees, which is half the angle of a right-angle
corner of the plate member. The distal end 5 of the diagonal slider 4 has an arrowhead
shape. A bearing 6 is provided in the distal end 5. A joint end of the circular guide 8
dedicated for the jigsaw 1 is rotatably joined to the bearing 6.
[0018]

FIG. 3 is a front view of the type-1 jig 2a. The type-1 jig 2a is attached to theplate member so as to hold the plate member with the fixing attachments 3 pushed
against the rear face portions near a side A and a side B of the plate member. The sideA and the side B join each other at the right-angle corner which is to be processed into aquadrant round corner. In FIG. 3, the state of the bearing 6 in the distal end 5 joined
to the circular guide 8 is illustrated.
[0019]

When attaching the type-1 jig 2a to the plate member, first, the distal end 5,

having an arrowhead shape, of the diagonal slider 4 is positioned at a vertex G of theright-angle corner by sliding the diagonal slider 4, and then, the two fixing attachments
3 are screwed to fix the plate member on the rear side of the plate member. In thisstate, the bearing 6 in the distal end 5 of the diagonal slider 4 is always on the 45-degreeline when moved within the sliding range of the diagonal slider 4. Thus, the distancefrom the side A to the bearing 6 is the same as the distance from the side B to thebearing 6, regardless of the position of the bearing 6. Now, a quadrant round corner
can be made with high accuracy by a single cut by the following procedure: positioning aside face of the jigsaw blade 10 of the jigsaw 1 at a start point of cutting the side A or theside B; fastening the screws of the screw-equipped guiding blocks 7 of the diagonalslider 4 and a screw of a circular guiding block 9; and moving the jigsaw 1 along withthe rotating circular guide 8 to the other one among the side A and side B, thereby
cutting the plate member.
