Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to an electrically heated evaporator in which a cord is wound inside a container, and more particularly, in such an evaporator Related to the improvement of the lamp mechanism for visually confirming the energized state.

[Conventional technology]

2. Description of the Related Art Conventionally, there is known an electrically heated vaporizer in which a pilot lamp is arranged in the vaporizer in order to confirm the energization state. For example, in Japanese Utility Model Publication No. 60-3737, the 14th
As shown in the figure, the evaporator main body 50 has a shaft body 52 around which a cord is wound around the lower periphery, a lid body 53 fixedly attached to the shaft body 52 with a screw or the like, and a shaft body 52. It is composed of a rotatable lower cap 54 which is prevented from coming off, a pilot lamp 55 is arranged on the central outer plane of the shaft body 52, and the pilot lamp 55 is provided on the corresponding upper lid body 53. The openings 56 and the like are arranged so that they can be visually recognized.

[Problems to be solved by the present invention] In the conventional example as described above, in order to accommodate the cord wound around the lower outer peripheral side of the shaft body when the evaporator is not used, one of the lower caps is used. It is carried out by rotating the lid body, which is held in a state of being integrally fixed to the shaft body, with the other hand and relatively rotated with respect to the lower cap with the other hand.

For this reason, it is necessary to grasp the combination of the shaft body and the lid body on the rotating side with the palm, so the size cannot be made too large, but it is inevitable that a heating element is incorporated in the shaft body. In addition, the storage space for the pilot lamp, which is placed on the shaft more for service, is limited, and it is difficult to assemble the pilot lamp-related parts when manufacturing the vaporizer, and the pilot lamp space is small in the completed vaporizer. There was a problem that it was difficult to confirm the energized state.

The present invention has been made in view of the above points, and it is an object of the present invention to provide a vaporizer in which a large portion of a lamp cover for displaying a pilot lamp can be taken and the energization state can be easily confirmed. .

〔Example〕

The general appearance of the heating vaporizer according to the present invention is shown in FIG. 1, which is a fixed support at the bottom, as shown in more detail in FIG. 2 which is an exploded perspective view thereof. A lower container 5 forming a body, a rotating portion main body 4 composed of a combination of a lower rotating container 3 rotatably supported on the lower container 5 and an upper rotating container 2, and an upper side of the upper rotating container 2 are exposed. The lower container 5 and the upper container 1 rotatably support the rotating part main body 4 inside by fixing the outer peripheral part of the lower container 5 to the outer peripheral part of the lower container 5.

Hereinafter, these basic elements will be sequentially described.

Lower Container As shown in FIG. 2, the lower container 5 basically has a container shape in which a substantially square bottom wall 6 to four peripheral walls 7 are erected. A rotary shaft 8 is erected at the center of the bottom wall 6,
An annular frame 9 is erected near the outside of the bottom wall 6 at an equal distance from the rotary shaft 8. A code groove 11 for introducing the code 10 into the lower container 5 is formed at an appropriate position on the four-sided wall 7, and an annular frame 9 adjacent to the code groove 11 is formed.
A part of is also cut out.

Near the corners of the bottom wall 6 of the lower container 5, there are prepared cylindrical leg portions 12 whose upper portions are open to the inside and outside of the annular frame 9, respectively.
While avoiding the risk of heat transfer to the floor during use of the evaporator by separating the bottom wall lower part of the lower container 5 from the floor, the inside of the cylindrical leg 12 on the invisible side is opened. The outer side of the lower container 5 and the lower container 4
A ventilation path is formed between the inside and the inside.

The lower container 5 is further provided with a hanging portion 13 standing upward from the four peripheral walls 7 near each corner, and is also engaged on the bottom wall 6 between the annular frame 9 and the four peripheral walls 7 at one corner. The pivot 14 for the stop member is provided upright, and its function will be described in detail later.

Rotating part main body The rotating part main body 4 is basically composed of a rotating container upper part 2 and a rotating container lower part 3.

As shown in FIGS. 3 and 4, the lower part 3 of the rotary container has the bearing opening 16 at the center of the disk portion 15 and the lower part 5 of the rotary container described above.
It is adapted to be loosely fitted to the central rotating shaft 14 from above, and an annular partition wall 17 hangs below the disk portion 15 at a substantially intermediate portion between the bearing opening 16 and the circumferential portion. The annular partition wall 17 defines an annular outer peripheral chamber and an annular inner peripheral chamber. The annular outer peripheral chamber is a space for accommodating the cord 10 wound on the annular partition wall 17, and the annular inner peripheral chamber urges the lower part 13 of the rotary container, that is, the rotating part main body 4 in the direction in which the cord 10 is wound. A spiral leaf spring 18 is stored. Above the disc portion 15, holding portions 21 for inserting and fixing both legs of the heating element holder 20 that holds the heating element 19 downward are formed at positions equidistant from the bearing opening 16. On the circumferential surface of the disc portion 15, there is provided an engagement protrusion 22 that engages with a locking port provided in a hanging wall portion of the upper part 2 of the rotary container described later. A holder 24 of the fuse 23 is arranged near the circumference of the disc portion 15.

As shown in FIGS. 2 to 4, the upper part 2 of the rotary container has an opening 25 exposing the heating element 19 at the center, and the opening 25 has a mat placed on the heating element 19. An appropriate number of bridges 26 are laid across in an arch to prevent the bridges from shifting. The upper outer peripheral side portion of the upper part 2 of the rotary container is once hung downward and then bent outward to form a step portion 27 on the outer periphery.
And the upper part of the rotating container 2, that is, the rotating part main body 4 is stably supported by the opening 41 of the upper container 1 due to the existence of the step 27, and can rotate on the rotating shaft 8 of the lower container 5. Has become.

The outer peripheral side below the step 27 is again an annular hanging wall.
28, and the locking holes 29 are formed at appropriate intervals in the circumferential direction of the annular hanging wall portion 28.
The upper part 2 of the rotary container and the lower part 3 of the rotary container 3 are engaged by snap-engaging engagement projections 22 protruding upward from the lower part 3 of the rotary container.
A strong bond of is established. Below the annular hanging wall portion 28 is a circular flange portion 30 extending outward. One lower portion of the annular hanging wall portion 28 is cut out, and a lamp holder 32 for holding the lamp 31 is erected on the circular flange portion 30 immediately below this portion. An opening 33 is provided on the surface of the upper rotary container upper part 2 where the lamp 31 holder 32 is arranged, and a green light guiding material 34, for example, is arranged from the lamp holder 32 through the opening 3 to the upper part. The light when the lamp 31 is turned on is guided to the upper part 2 of the rotary container to indicate that the vaporizer is energized.

The outer peripheral contour of the circular flange portion 30 located on the outermost periphery of the rotary container upper portion 2 matches the outer peripheral shape of the disk portion 15 of the rotary container lower portion 3. That is, although these shapes are almost circular,
Locking claws 36 of the locking member 35 for preventing the rotary body 4 from rotating in the winding direction of the cord 10 by the spiral leaf spring 18 are provided at one or more positions in the circumferential direction. A notch 40 that abuts is provided.

That is, after the rotary body 4 is set on the rotary shaft 8 of the lower container 5, the locking member 35 having the shape shown in FIG. 2 is externally fitted onto the 5 locking shaft 14 of the lower container from above. Locking member 35
When the upper container 1 described later is fixed to the lower container 5, the retaining ribs projecting downward from the upper container prevent the upper container 1 from coming off upward.

The structure of the locking member 35 itself is such that the end surface on one side forms a locking claw 36 across the point pivotally supported by the locking shaft 14, and the inner side upper part on the locking claw 36 side is engaged. There is a retaining surface 37,
Further, a pressing portion 38 is formed on the outer side opposite to the pivot point, and the pressing portion 38 is provided outside the opening provided on the outer peripheral wall of the upper container 1 when the upper container 1 described later is fixed to the lower container 5. It is designed to project toward. (See FIG. 1). The locking member 35 has a structure in which the locking claw 36 side is always biased from the outside toward the inside by an elastic body 39. Therefore, the locking claw 36 of the locking member 35 is normally engaged with any one of the notches 40 formed on the outer peripheral portion of the rotating portion main body 4 and is coded by the spiral leaf spring 18 of the rotating portion main body 4. The rotation in the winding direction of 10 is stopped.

However, when the pressing portion 38 at the opposite end of the locking claw 36 of the locking member 35 is pressed toward the center so as to oppose the urging force of the elastic body 39, the locking claw 36 is provided on the outer periphery of the rotating portion body 4. The engagement with the notch 40 is released, and the rotating portion body 4 is rotated in the winding direction of the cord 10 by the action of the spiral leaf spring 18.

By the way, the notch 40 is not symmetrical in its plan view, and has a saw-tooth notch in which one side is much longer than the other side. Therefore, although the locking member 35 performs an effective locking action of the rotating portion main body 4 with respect to the rotation in the direction in which the locking claw 36 of the locking member 35 abuts the short side of the notch 40,
Conversely, the locking claw 36 of the locking member 35 is attached to the long side of the notch 40.
The locking member 35 does not effectively lock the rotary unit main body 4 with respect to the rotation in the sliding contact direction. Therefore, when the upper container 1 or the lower container 5 is grasped by one hand and the cord 10 is pulled, the notch 40 on the outer circumference of the rotating part body 4 is freely rotated without being restrained by the locking claw 36. It will be. Then, when the pulling of the cord 10 is stopped at an appropriate position, the rotating portion main body 4 starts to rotate in the direction in which the cord is wound by the leaf spring 18, but the locking claw 36 comes into contact with the notch 40 during the rotation. , The rotation will be stopped immediately.

Further, in this type of winding locking mechanism, in order to disengage the locking claw 36 and the notch 37, the locking member 35 is projected outward from the upper container on the opposite side of the locking claw 36. When the pressing portion 38 that is being pressed is pressed, the rotating body 4 rapidly starts to rotate because the winding force of the spiral leaf spring 18 is large, and the bottom surface of the rotating body 4 moves vertically and horizontally with respect to the rotating shaft 8. With a large fluctuation,
That is, it rotates in a "dancing" state. Therefore, in general, one-sided wear of the bearing opening 16 and the rotary bearing 8 is likely to occur, and problems such as locking failure are likely to occur.

In the embodiment of the present invention, means for coping with such a problem is provided. First, with respect to vertical deflection, the circular shape of the upper part 2 of the rotary container of the locking pressing surface 37 prepared on the locking member 35 is provided. Vertical movement of the upper surface of the flange portion 30, that is, vertical movement of the entire rotating portion main body 4, is restricted. Next, with respect to the left and right runout of the rotary unit main body 4, the inner surface of the locking member 35 in the non-locked state is brought into close contact with the outer peripheral surface of the rotary flange portion 30 of the rotary unit main body 4 as much as possible. , So that the shake can be prevented. In addition, when the locking member 35 is not locked, that is, when the pressing portion 38 of the locking member 35 is being pushed from the outside, the inner surface of the pressing portion 38 is increased by increasing the pressing degree. The rotary body 4 has a structure that provides frictional braking to the outer periphery of the rotary flange surface of
The rapid rotation itself may be restricted.

Upper Container The upper container 1 is a member that basically covers the upper part of the lower container 5, so that its lower contour is shaped to fit relative to the upper contour of the lower container 5, and each of them. Hooking part standing upright from the lower container 5 near the corner
An engaging portion that engages with 13 is appropriately formed, and by engaging both, the upper container 1 and the lower container 5 form a strong connection. The upper part of the upper container 1 exposes the upper part of the rotating part body 4 to the outside, and rotates the rotating part body 4 inside the combined structure of the upper container 1 and the lower container 5 without rattling. Circular opening in the center for
Has 41.

One or more lamp covers 42 are appropriately fitted to the outer surface of the circular opening 41 in the upper container 1, and the rotary body 4 is locked by the locking claws 36 of the locking member 35 at each position of the lamp cover 42. The lamp 31 arranged on the rotating portion main body 4 is designed so as to correspond to one of the lamp covers 42 when the rotation of the cord 10 in the winding direction is stopped. Therefore, when there is only one lamp cover part 42, there is also one notch 40 provided on the outer peripheral portion of the rotating part body 4, and when the rotating part body 4 is prevented from rotating by the locking member 35, The only lamp cover 42 and the lamp automatically correspond to each other and have a positional relationship.

In addition, at night, when the lamp is too bright and it is desired to energize it in the off state, it is possible to lock it at a position without a lamp cover, or to provide a small lamp cover and lock at that position. .

As for the lamp cover 42, one or more places can be arranged in the upper container 1 as described above.
The arrangement part of the lamp cover 42, the shape of the cover, and the color and the arrangement method of the light guide material 34 can be variously modified, and FIGS. 5 to 12 show typical examples thereof. is there.

[Effect of device]

According to the present invention described in detail above, in the heating vaporizer of the type in which the cord is housed inside, it is possible to obtain a structure in which the lamp cover does not have to be arranged on the rotating part side, and the lamp cover holds a part thereof. Since it can be arranged on the side of the fixed part that is good only, a large space can be taken, and the position of the heating evaporator can be easily confirmed at night and it is safe. Further, since a sliding contact portion is not required in the electric wiring while adopting the rotation mechanism, the failure is unlikely to occur even if it is repeatedly used frequently.

Further, even if the lamp is arranged on the rotating side, when the rotation is stopped, it coincides with the stationary lamp cover portion, so that it is not necessary to adjust the degree of rotation.
