Description

[Detailed Description of the Invention] The present invention relates to a boiler in which the rotating direction of the handle can be changed.

The handle attached to the top end of the boiler has its base end pivoted to the pivot member of the outer case, and the other end removably engaged with the lock member of the outer case, so that the lid can be opened. It can be rotated to open and close.

However, in the past, since the pivot member and the lock member were fixed to the outer case, the rotating direction of the handle was determined in advance, which could make it extremely difficult to operate depending on the user's skill.

In other words, for example, when a boiler is placed with the operating section with switches, indicator lamps, etc. arranged in front, if the pivot member of the handle is on the left side, the handle will move upward to the right, that is, counterclockwise. It can be rotated, but this is easy to operate if a right-handed user holds a rice scoop or the like in his right hand and grasps the handle with his left hand, but for left-handed users, it is difficult to rotate the handle with his left hand. Later, the user had to transfer the rice scoop etc. to his left hand, and since the left side of the boiler was the pivot point for the handle, it was extremely inconvenient as it got in the way and made the rice scoop difficult to handle.

Conversely, if the pivot point of the handle was on the right side, it would be difficult for a right-handed user to operate the handle due to the exact opposite situation.

The present invention was developed in view of the above circumstances, and its purpose is to replace the pivot member that pivots the base end of the handle and the lock member that locks the other end with respect to the outer case. To provide an easy-to-use boiler which can be attached easily and allows a user to easily change the rotating direction of a handle to a direction that is easy to operate, regardless of whether the user is left or right-handed.

An embodiment of the present invention will be described below with reference to the drawings.

Reference numeral 1 denotes an outer case that houses a pot 2 and a well-known boiling heating device (not shown); 3 a hinge stand that is a pivot member that is removably attached to the outer case 1; The proximal end portion 5a of 5 is rotatably supported.

Reference numeral 6 denotes a retaining pawl provided at the other end of the handle 5, which engages with a locking member 7 detachably attached to the outer case 1 and can be released from its retaining by pressing a push button 8. has been done.

A lid 9 is attached to the handle 5 and moves together with the handle 5 to open and close the opening of the pot 2 when the handle 5 is rotated.

Reference numeral 10 denotes an operation box equipped with a switch 11 and an indicator lamp 12 and attached to the outer case 1.

Now, the hinge base 3 and the lock member 7, which are pivot members of the handle 5, will be described in detail with reference to FIG.
．． 13 and the surface that abuts on the outer case 1 are integrally formed with two engaging protrusions 14.1!1 whose cross sections cut out from the engaging part 14a and the retaining part 14b form a substantially convex shape, The locking member 7 also has a locking portion (not shown) with which the locking claw 6 of the handle 5 engages, and has the same shape and the same spacing as the locking projections 14 and 14 of the hinge base 3 on the surface that comes into contact with the outer case 1. Two locking protrusions 15.15 are integrally formed.

By the way, as shown in FIG. 3, a pair of left mounting holes 16.16 and a pair of right mounting holes 17.17 are formed in the peripheral wall of the outer case 1 on both sides in the radial direction. The mounting holes 16.16 and 17.17 are each of the same shape.

Therefore, if we describe the shape of the left mounting hole 16, the left mounting hole 16 has an insertion hole portion 16a that is slightly larger than the retaining portion 14b of the engagement protrusion 14, and a vertical width of the engagement protrusion 1.
The locking hole portion 1 has approximately the same dimensions as the upper and lower thickness of the engaging portion 14a of No. 4.
6b are shaped to be continuous in the horizontal direction.

Therefore, for example, in order to attach the hinge stand 3 to the left mounting hole 16.16, the engaging protrusions 14, 14 are inserted into the insertion holes 16a, 16a of the left mounting hole 16.16, and the retaining portions 14b are inserted.
, 14b are projected into the outer case 1, and in this state, the hinge stand 3 is moved along the peripheral wall of the outer case 1 toward the locking hole 16b.

Then, the engaging parts 14 a , 14 a and the locking hole part 16
b , 16 b are inserted and tightly fitted, and the retaining portions 14 b, 14 b of the engaging protrusion 14 support both upper and lower peripheral edge portions of the locking hole portions 16 b, 16 b between the hinge base 3; A hinge stand 3 is attached to the left side of the outer case 1.

In the boiler constructed as described above, the left mounting hole 16.16 and the right mounting hole 17.17 of the outer case 1 have the same shape, and the engagement protrusion 14.14 of the hinge base 3 and Since the locking protrusions 15 and 15 of the locking member 7 have the same shape, the hinge base 3 and the locking member 7 can be attached to either the left or right mounting hole.

When the hinge base 3 is installed in the left mounting hole 16.16 of the outer case 1 and the locking member 7 is installed in the right mounting hole 17.17 (see Fig. 1), the rotation direction of the handle 5 is reversed. The direction is clockwise, which is convenient for right-handed users who hold a rice scoop or the like in their right hand as described above.

However, for left-handed users who hold a rice scoop or the like in their left hand, it is difficult to operate a boiler in which the handle 5 rotates counterclockwise, so in this case, the direction of rotation can be changed as follows. can.

That is, the push button 8 of the handle 5 is pressed down to release the engagement between the engagement pawl 6 and the lock member 7, and the hinge base 3 is moved along the peripheral wall of the outer case 1 to the insertion hole 16a side of the left mounting hole 16. When moved, the engagement protrusions 14.14 are inserted into the insertion holes 16a, 16.
a, and the hinge stand 3 can be removed from the outer case 1.

Then, remove the locking member 7 from the right mounting hole 17.17 in the same manner, and then convert the locking member 7 to the left mounting hole 16.16 and the hinge base 3 to the right mounting hole 17.17 and install them. 5 is a clockwise rotation direction, making it easier for left-handed users to operate.

Moreover, the operation of attaching and detaching the hinge stand 3 and the lock member 7 is as follows.
It is extremely easy to do since it simply moves them laterally.

As is clear from the above description, the present invention makes it possible to attach and detach the pivot member that pivots the base end of the handle and the lock member that locks the other end of the handle without using any tools. Since the mounting positions of the pivot member and the lock member are made interchangeable so that the direction of rotation of the handle can be changed, the direction of rotation of the handle can be changed even if the user's dominant arm is left or right. It is possible to provide a boiler that can be changed in a direction that is easy to use, and that can be changed very easily.
