Description

[Detailed Description of the Invention] The present invention relates to a water heater handle attachment device that notifies the boiling of water by blowing a reed.

For this type of water heater, the blowing effect of the boil alarm reed is affected by the leakage of boiling steam pressure, so it is necessary to ensure that the spout cover is completely closed to the spout, so it is necessary to A spout lid opening/closing operating arm is inserted into the spout lid so that it can move forward and backward, and the operating arm and the spout lid are connected via a dead point passage mechanism. They are often installed in a cantilevered manner, making it difficult to securely install them.

The present invention was developed with the aim of firmly mounting the handle mounted in a cantilevered manner as described above in a stable state without wobbling back and forth, left and right, and up and down. do.

In FIG. 1, reference numeral 1 denotes a container body of a water heater, and a spout 2 is watertightly attached to the front of the container, and a handle 3 is attached in a cantilevered manner to the rear upper part.

Reference numeral 4 denotes a lid that is detachable from the container body 1, and a blowing device 6 (details are omitted) having a reed 5 is housed in the center thereof, and a knob portion 7 is provided.

Reference numeral 8 denotes a spout lid for opening and closing the spout 2, which is rotatably supported by a pivot pin 10 on a bearing plate 9 attached to the container main body 1, and is provided in a recess on the lower surface of the front inclined portion 3a of the handle 3. It is connected by a connecting pin 12 to one end of an operating arm 11 that moves forward and backward within the U-shaped hole 3b.

Reference numeral 13 denotes a substantially C-shaped leaf spring mounted between the bearing plate 9 and the connecting pin 12, and the connecting pin 12 in the opening/closing position of the spout lid 8 is connected to the attachment part of the leaf spring 13 to the bearing plate 9. The spout lid 8 is set to exceed the dead point connecting with the pivot pin 10.
This functions to restrict the opening and closing position of the opening/closing position.

The cantilevered mounting portion 3c of the handle 3 is provided with a fitting groove 3c ₁ having an expanded opening at the lower end into which a mounting fitting to be described later is fitted, and the outer portion 3
A plurality of screw insertion holes _3c3 are provided through _c2 .

As shown in FIG.
A contact part 20a formed to have approximately the same width as the rear wall width of c ₁ , and a mounting part 2 connected to the contact part 20a hanging down from the center part and forming a plurality of screw hole bosses 20b ₁ .
0b, a pair of reinforcing parts 20c bent from both sides of the mounting part 20b to have substantially the same width as both side wall widths of the fitting groove 3c ₁ , and a pair of reinforcing parts 20c formed from the lower end of each reinforcing part 20c to the fitting groove 3c _1. The substrate portion 20d is bent to a size that fits into the inner circumferential wall of the lower end expansion opening, and has a plurality of through holes _20d1 .

Next, the process of attaching the handle 3 to the container body 1 via the above-mentioned mounting bracket 20 will be explained. First, the reinforcing plate 21 is attached to the inner wall surface of the container body 1,
The crimping studs 22 are inserted through the plurality of through holes formed in the reinforcing plate 21 into the container body 1 through through holes formed in alignment with the through holes, and the crimping rivets 22 are inserted into the upper surface of the container body 1. Insert the protruding part into the through hole _20d1 provided in the base plate part 20d of the mounting bracket 20 and tighten it,
The mounting bracket 20 is attached and fixed to the container body 1.

Next, the mounting bracket 20 is fitted into the fitting groove 3c ₁ of the cantilevered mounting part 3c of the handle 3, and the screw 23 is inserted through the screw insertion hole 3c ₃ of the outer part 3c ₂ to attach the mounting bracket 20.
is screwed into the screw hole boss _20b1 of the mounting portion 20b and fastened.

The handle 3 attached to the container body 1 as described above is housed so as to cover the mounting bracket 20 with its cantilevered mounting portion 3c, and also covers one entire surface and both end surfaces of the contact portion 20a of the mounting bracket 20. is the fitting groove 3
Since the reinforcing _portion 20c is in contact with the rear wall surface and both side wall surfaces of the reinforcing portion 20c, and each longitudinal end surface of the reinforcing portion 20c is in contact with the front and rear wall surfaces of the fitting groove _3c1 , the handle 3 will not wobble in the front and rear and left and right directions. .

In addition, since the outer part _3c2 of the handle 3 is attached to the attachment part 20b of the mounting bracket 20 with screws 23, the handle 3 does not wobble up and down, and the attachment bracket 20 is attached to the inner wall surface of the container body 1. Since it is attached together with the attached reinforcing plate 21, the outer wall of the container body 1 will not be deformed even when the water heater is moved by gripping the handle 3.

As mentioned above, the present invention provides a fitting groove in the cantilever-type mounting part of the handle, and attaches a fitting to the container body together with a reinforcing plate in a shape that contacts the front, rear, and both side walls of the fitting groove. The simple structure of fitting the mounting bracket into the fitting groove of the handle and securing it with screws allows the handle to be firmly and stably attached to the container body without wobbling, making it extremely easy to use. be.
