Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to the structure of an electric stove having a quartz tube heater unit.

Structure of conventional examples and their problems Conventionally, among electric stoves, those that have a swinging device in which the main body swings from side to side,
As shown in FIG. 3, a swinging timing motor 103 is mounted on the top of a flat bottom plate 102 that is engaged with the lower end surface of the main body case 101, and a crank 104 connected to the timing motor 103,
There is a problem in that the swinging portion of the rod 105 is exposed to the outside, which is not desirable from a safety standpoint.
Furthermore, when a flat bottom plate 102 is disposed inside the main body case 101 as shown in FIG.
02, the balance of the bottom plate 102 is difficult to obtain, and therefore, the main body case 101 tends to be installed at an angle.

In addition, conventional stands with a swing drive device installed inside the stand solve the above-mentioned problems of safety and stability, but the swing drive device on the fixed side and the power switch located on the movable side A connection with the heater unit is required, and a relay lead wire must be wired near the center of rotation, which poses a problem in that assembly such as connection processing becomes complicated.

Purpose of the invention The present invention aims to solve these conventional problems, and aims to improve safety, improve the stability of the bottom plate attachment method, and improve quality.

Composition of the invention In order to achieve the above object, the electric stove of the invention includes a main body case containing a built-in heater unit,
The main case includes a bottom plate provided at the lower part of the case, and a stand, and the bottom plate has a bottom part that is fixed to the lower edge of the case, and a box-shaped recess that stands upward from all four sides of the bottom part. A swing drive device for swinging the main body case is built into the recess of the bottom plate, a shaft protruding downward is provided at the center of the recess of the bottom plate, and the shaft is connected to a spacer in the swing drive device. The electric stove is constructed such that the electric stove is inserted through an insertion hole of an arm that also serves as an arm, and is inserted into an insertion hole of a stand, and the main body case is supported by the stand so as to be horizontally rotatable.

DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. 1 and 2.

In FIGS. 1 and 2, reference numeral 1 denotes a vertically elongated main body case with an open front, which includes a vertical quartz tube heater unit 2 and a parabolic reflector 3 whose focal point is at the center of the quartz tube heater unit 2. There is a power switch 4 at the bottom to turn the power on and off.
has been established. On the lower end surface of this main body case 1,
A bottom plate 14 is provided. The bottom plate 14 has a bottom part 5 that is locked to the lower end bent part 6 of the main body case 1, and a box-shaped recess 7 that stands upwardly from the bottom part 5 from all sides. This recess 7 is provided with a swing drive device, the details of which will be explained below. A shaft 8 projecting downward is fixed at the center of the storage portion 7, and this shaft 8 is inserted into an insertion hole 9a of the arm 9 and an insertion hole 10a formed in the stand 10. In addition, this arm 9 has a storage section 7 and a stand 10.
It acts as a spacer and protects the central shaft (shaft 8) during rocking drive. By fixing the arm 9 to the stand 10, the recess 7 of the bottom plate 14 and the main case 1 are configured to be swingable relative to the stand 10. The arm 9 is rotatably connected to a bow-shaped rod 11, and the other end of the rod 11 is rotatably connected to a crank 13 whose center portion is fixed to a timing motor 12. The timing motor 1
2 is placed and fixed on the upper side of the storage section 7 of the bottom plate 14.

In the above configuration, when the power switch 4 is turned on,
The quartz tube heater unit 2 is energized, and the heat generated therefrom is radiated forward either directly or reflected by the parabolic reflector 3. At the same time, the timing motor 12 is energized and the crank 1 engaged therewith.
3, the rod 11, and the arm 9, the main body case 1 swings left and right with respect to the stand 10. Furthermore, the arm 9, rod 11, crank 13, main shaft of the timing motor 12, etc., which are the constituent members of the swing drive device,
Since it is built in between the recess 7 of the bottom plate 14 and the stand 10, it is not exposed to the outside, and the bottom part 5 of the bottom plate 14 is connected to the lower end bent part 6 of the main case 1.
By being locked with this, stability is increased and quality is improved.

Although this embodiment describes an embodiment for an electric stove, it goes without saying that the same effect can be achieved in an electric stove with a fan that has a built-in fan motor.

Effects of the Invention As is clear from the description of the above embodiments, according to the electric stove of the present invention, the bottom plate provided at the lower end of the main body case has a rocking drive device in a recess that stands upwardly from the bottom surface from all sides. Since it is built-in, the rocking drive device is not exposed to the outside, and stability is increased at the joint surface between the main body case and the bottom plate, which has a significant effect on improving product quality.
