Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a swing display device for a so-called double swing electric stove, electric fan, etc. whose main body rotates from side to side.

BACKGROUND ART FIG. 4 shows an external view of a double-oscillation electric stove generally available on the market, and FIGS. S and 6 show its double-oscillation mechanism.

That is, a fixed base 2 is fastened to the upper part of the leg 1, and a main body consisting of a heater 3, a reflector 4, a guard 5, a body 6, etc. is rotatably mounted on the upper part, and a double swing mechanism is installed inside the fixed base 2. The double swing mechanism will be explained below with reference to FIGS. 5 and 6.

The fixed base 2 is provided with a bearing part 2a, into which the rotary shaft 8, which is caulked by the rotary base 7 with crimping@6a, is inserted, and the upper end of the rotary base 7 and the bearing part 2a of the fixed base 2 is connected. A ratchet receiver 9 rotatable on the rotating shaft 8 is provided between them. A motor 10 is fastened to the rotary table 7, one end of an arm 11 is fixed to the motor shaft 10a, and one end of a coupling WL12 is rotatably inserted into the other end of the arm 11. The other end of the continuous plate 12 is rotatably inserted into the connecting plate insertion portion 9a of the ratchet receiver 9. Ratchet receiver 9
Oval-shaped recesses 9b are formed at 15° intervals in the fan-shaped portion, and a ratchet tip 14 guided by a chimp guide portion 2b extending from the fixed base 2 and biased by a spring 13 is brought into contact therewith. The lower part of the rotary table 7 is fastened to the back plate 15,
A body 6 is fastened to the back plate 15.

Therefore, when the body 6 is turned left and right by hand, the back plate 15, rotating table 7, motor 10, arm 11, connecting plate 12, ratchet receiver 9, and rotating shaft 8 rotate together, and the ratchet tip 14 rotates between the ratchet and the As it moves in and out of the concave portions 9b of the receiver 9, a click feeling is generated, and when the hand stops, the ratchet tip 14 engages with one of the five concave portions 9b (hereinafter, this manual rotation is referred to as free swinging).

Next, the case where the motor 10 rotates will be explained with reference to FIG. In this case, as described above, the ratchet receiver 9 engages with the ratchet tip 14 and is fixed to the fixed base 2. Therefore, in FIG. 7, the center C of the connecting plate insertion portion 9a
2 is the fixed center.

The center C3 of the motor shaft 10a is rotatable on the orbit A around the center C1 of the rotary shaft 8 by the rotary table 7, and the center C4 of the arm 11 is because C2 and C4 are connected by the connecting plate 12. It is rotatable on orbit B centered on C2. Now when the motor shaft 10a rotates in the direction of arrow D1, C
3 rotates on orbit A in the direction of arrow D2. Heel C4 also rotates on orbit B in the direction of arrow D2 while keeping the same distance from C3. Then, when C3 reaches C5 where C3C4=C5C6, C6r, C4, yl-, C3 starts rotating in the direction opposite to arrow D2. Similarly, when C3 reaches C7 and C4 reaches C8, which are C3C420706, C3 starts rotating again in the direction of arrow D2. As explained in the structure using Figures 5 and 6, this means that
Since the center C3 of the motor shaft 10a is in a positionally fixed relationship with the body 6, this means that the body 6 rotates (hereinafter, this rotation by the motor is referred to as automatic swing).

In this way, in the conventional so-called double-oscillating electric stove, the main body rotates at a fixed angle left and right (automatic oscillation) by a motor, and the center position of the rotation angle of the automatic oscillation is manually adjusted (free-oscillation). Therefore, the direction can be changed without lifting the legs, and the automatic swinging of the head allows for heating over a wide area.

Problems to be Solved by the Invention However, with the conventional structure, there was a problem in that the user could not know the center position of the rotation angle of the automatic swing until the automatic swing was reciprocated once.

Means for Solving the Problems In order to solve the above-mentioned problems, the present invention provides a light emitting body on a ratchet receiver that moves the center position of the rotation angle of the automatic swing, and a light emitting body is provided to correspond to the rotation of the ratchet receiver. A plurality of optical fibers whose light-receiving ends face the light emitter are provided on a fixed base, and each light emitting end of the plurality of optical fibers is provided on the surface of the fixed base.

Function Since the present invention has the above-described configuration, when the ratchet receiver that moves the center position of the rotation angle of the automatic swing rotates, the light emitting body also moves together with the ratchet receiver, and the plurality of optical fibers facing the light emitter move. The light-receiving end of the light-receiving end is switched sequentially, and the position of the light emitter, that is, the center position of the rotation angle of the automatic swing, can be displayed on the surface of the fixed table through the optical fiber.

Embodiment FIG. 3 shows an external view of an embodiment of the electric stove of the present invention. Note that the same members as in the conventional example are given the same reference numerals, detailed explanations are omitted, and the explanation will focus on the differences from the conventional example.

In FIG. 3, the fixed base 16 is provided with light emitting sections 17a1 to 17a5 of the optical fiber 17 (FIG. 1).

Figures 1 and 2 show its internal structure. The ratchet receiver 9 is provided with a light emitting body 18, and the fixed base 16 is provided with five optical fibers 17-1 to 17-5.
The light-receiving ends 17b1 to 17b5 of the five optical fibers 17-1 to 17-5 are provided so as to face the position of the light emitter that is stationary when the ratchet chip 14 is engaged with each of the five recesses 9b. The other end of the optical fiber 17, that is, the light emitting ends 17a1 to 17a5, is provided so as to face the inclined surface of the fixed base 16. The rest of the structure is the same as that of the conventional example, so a description thereof will be omitted.

Next, the operation of this embodiment will be explained. When the body 6 is turned by hand, the ratchet receiver 9 rotates around the rotating shaft 8 as described in detail in the conventional example, and when the body 6 is stopped, the ratchet receiver 9 rotates at 5.
The ratchet tip 14 engages with one of the two recesses 9b and becomes stationary. At this time, the light emitter 18 provided on the ratchet receiver 9 faces any one of the light receiving ends 17b1 to 17b5 of the five optical fibers 17-1 to 17-5, and the light emitter 18
The light of No. 8 passes through one of the five optical fibers 17 and reaches the five light emitting ends 17a1 to 17a provided on the fixed base 16.
Make one of 5 shine. In FIGS. 1 and 2, the ratchet chip 14 is now engaged with the central recess 9b of the five recesses 9b of the ratchet receiver 9, and the light emitter 18 is connected to the five optical fibers 17-1 to 17-5. Light receiving end 17b exactly in the center
3 and five light emitting ends 17 provided on the fixed base 16.
The central light emitting end 17a3 of a1 to 17a6 is illuminated to indicate that the electric stove is in a state of automatic swinging around the direction of arrow A in FIG. 2, which is the entire front.

As described above, according to this embodiment, since the center position of the automatic swing is displayed on the fixed base by light, there is an advantage that there is no need to wait for one round trip for the automatic swing as in the conventional example.

Effects of the Invention According to the present invention, since the center position of the automatic swing is displayed on the fixed stand by light, there is an effect that it is easy to orient an electric stove, an old man blower, etc. in the direction in which you want to take heat.
