Description

[Detailed Description of the Invention] This invention relates to a water heater, and particularly relates to an improvement in the mounting structure for rotatably attaching a double-sided handle to the body.

Conventionally, the handle installation configuration in which a double-sided handle is rotatably attached to a water heater involves placing the leg plate of the handle facing a plate-shaped mounting bracket installed upright on the side of the water heater, and attaching the handle using a stud member inserted through both. Many are used that have a rotatable support structure.

However, in the above-mentioned handle mounting structure,
The rivet members are caulked to maintain the rotational angle position of the handle, so if the rivet crimping force is too strong, the handle will become stiff and difficult to turn; on the other hand, if the rivet force is too weak, , the handle will be easier to turn, but it will also become unstable, and if you put it on a stove, etc., even if it is kept upright, the slightest vibration will cause it to fall to the side, putting you at risk of overheating.

A possible solution to the above disadvantages is to interpose an elastic washer such as a wave-shaped washer between the mounting washer and the handle leg plate, but since the elasticity of the elastic washer changes depending on the strength of the riveting process, It is difficult to obtain an appropriate rotational holding force.

This invention was made in order to solve the above problem, and its main purpose is to provide a water heater with a double-sided handle that can reliably provide an appropriate rotational holding force that matches the handle. be.

The second object of this invention is to provide a water heater with a double-sided handle that has a smooth handle attachment part and can be easily cleaned.

In the water heater according to this invention, a holding seat body having a substantially cubic shape as a whole is installed upright on the part of the body where the handle is attached, and the holding seat body can allow the handle to be rotated. The split seat part is composed of split seat parts facing each other with a minimum free gap, and is screwed from one split seat part to the other split seat part through the shaft hole of the handle side plate inserted into the free gap. The coupling screw is used as the rotation axis of the handle, and the screw shaft portion within the free gap is
The handle leg plate is characterized by a structure in which an elastic washer is fitted to elastically hold the handle leg plate on the opposing surface of the split seat portion.

Next, this invention will be explained in detail based on drawings showing an example of its implementation.

In the drawing, 1 is the body of the water heater, 2 is the spout, 3 is the lid for opening the water pitcher, 4 is the squirting lid, and 5 is the handle with both ends.
It is rotatably supported by special aluminum holding and receiving seats A ₁ and A ₂ fixed to the upper surface of the container body 1 .

The front support base A ₁ and the rear support base A ₂ are
Each is cubic in shape, and its main parts are evenly distributed. In other words, the holding and receiving seats A ₁ and A ₂ are each composed of two divided seat portions 6 and 7 that face each other with a minimum free gap that allows the insertion of the end leg plate 5a of the handle 5, and one The split seat portion 6 is erected on the top surface of the container while being abutted against an L-shaped support fitting 8 fixed to the top surface of the container by rivets or welding, and screws 9 are screwed into the support fitting 8 from the outside. It is fixed to the vessel by attaching it to the vessel.

The other split seat portion 7 faces the upper half of the split seat portion 6 with a minimum free gap that allows insertion of the end leg plate 5a of the handle 5, and The threaded cylindrical portion 6a protruding from the surface is fitted into a recess 7a provided on the opposing surface of the split seat portion 7, and the threaded cylindrical portion 6a is fitted into the shaft hole 5b of the leg plate 5a of the handle 5.
, and insert a flat washer 10 and a corrugated washer 1 into the cylindrical part.
1 and insert the split seat part 6 through the split seat part 7.
By screwing the screw 12 into the threaded cylindrical portion 6a of the handle 5, the leg plate 5a of the handle 5 is rotatably supported within the free gap under pressure using the threaded cylindrical portion 6a as a support axis. .

A portion of the divided seat portion 6 constituting the holding and receiving seat body A ₁ for supporting the front leg of the handle 5 is brought into contact with the spout 2 and cooperates with the spout to open the empty space 13 (Fig. 2). ] is formed, and a support mechanism for the blowing lid 4 is incorporated in the empty chamber 13 thereof. That is, 14 is a frame fixed to the outside of the spout, 15
1 is a support arm protruding from a part of the blowing lid 4 toward the inside of the frame, 16 is a support shaft that rotatably supports the support arm on the frame, and 17 is a cam piece 18 provided on the support arm.
The blowing lid 4 is a U-shaped leaf spring disposed inside the frame so as to be engaged with the blower lid 4, and the blowing lid 4 can be rotated to open and close around a support shaft 16, and is closed and closed by the elastic action of the leaf spring 17. and is adapted to be resiliently held in the open position.

According to the above water heater configuration, the holding body
Divided seat portion 6, which constitutes A ₁ and A ₂ respectively,
7 face each other with a minimum free gap that allows rotation of the leg plate 5a of the handle, and a screw 12 connecting the two split seat parts 6 and 7 is attached to the leg plate 5a.
Since the corrugated washer 11 for pressing the handle leg plate 5a is fitted into the screw shaft portion within the free gap, the minimum free gap that allows rotation of the handle leg plate 5a is , does not change due to the tightening of the screw 12 that serves as the support shaft of the handle, and is always kept constant, and the frictional holding force when the handle is rotated is determined only by the elastic force of the corrugated washer 11. Therefore, an appropriate steering wheel rotation holding force can be obtained reliably.

In addition, as mentioned above, the handle leg plate 5a is attached with the screw 1.
If the screw 12 is fitted into the cylindrical portion 6a surrounding the screw 12 without being in direct contact with the screw 12, there is no fear that the screw 12 will loosen due to the frictional force generated when the handle is rotated. Furthermore, if there is a cylindrical portion 6a, there is an advantage that it can be used as a gap material for facing the divided seat portions 6 and 7.

Furthermore, as mentioned above, the handle holding seat body
When A ₁ and A ₂ are cubic, it is extremely advantageous because the holding and receiving seat body can be used as an assembly chamber for the support mechanism of the blowing lid.

In addition, if the handle holding/receiving seat bodies A ₁ and A ₂ are cubic-shaped and the handle leg plate 5a is rotatably inserted into the opposing gap between the divided seat parts, the handle mounting mechanism part is Since it is covered with a holding and receiving seat, it is extremely easy to remove dirt, and the product value can be improved by designing the appearance.

As described above, according to this invention, in a water heater in which a double-sided handle is rotatably attached to the body of the water heater, a handle having a substantially cubic shape as a whole is attached to the part of the body to which the handle is attached. A seat is erected, and the holding and receiving seat is composed of divided seat parts facing each other with a minimum free gap that allows rotation of the handle, and from one divided seat part to the free gap. The split seat part connecting screw screwed into the other split seat part through the shaft hole of the handle leg plate inserted into the handle serves as the pivot shaft for the handle, and the handle leg plate is attached to the screw shaft part in the free gap. Since an elastic washer for elastically holding the split seat portion is fitted on the opposing surface, a water heater that can form an appropriate rotational holding force for the handle without being affected by the tightening of the handle support shaft is obtained. It will be done.
