Description

[Detailed description of the invention] This invention relates to an electric opener in which the lower heater of the roasting chamber can be moved vertically, and the purpose is to improve the operability of the vertical movement and improve the roasting efficiency. It is something.

The implementation sequence of the present invention will be explained below with reference to the drawings. Reference numeral 1 is an open main body, inside of which a roasting chamber 2 is partitioned and a door body 3 which can be opened and closed is pivoted to the front opening of the roasting chamber.

A front operation panel 4 is disposed at the front opening edge of the roasting chamber, and control switches and operating knobs for a roasting heater, etc., which will be described later, are arranged on the panel.

The door body 3 is mounted on the upper edge of the front operation panel 4 and is pivotally supported by a shaft 5 provided above the front operation panel 4.

The roasting chamber 2 is provided with an upper heater 66 and lower heaters 1 and 7 on the upper and lower sides, respectively.
6 is fixedly supported between the side walls 9, 9 as a device below the ceiling wall 8 of the roasting chamber 2, and lead wires (not shown) are connected to the terminal pins 6', 6' as appropriate. Heat generation is controlled by a control switch 10 arranged on the operation panel 4.

One of the lower heaters 7.7 is attached to a reflecting plate 11 provided below the roasting chamber 2, and the reflecting plate 11 is movable up and down within the roasting chamber 2.

That is, the reflecting plate 11 is made smaller than the width between the two side walls 9 of the roasting chamber 2, and its both sides are slightly upwardly oriented KFFr.
A vertically elongated transparent hole is bent to form a heater mounting portion 12°12, the lower heaters 1 and 7 are fixedly supported between the heater mounting portions, and terminal pins 7' and 7' thereof are bored in the side wall 9. 13, 13, these terminal pins 7', ?
A lead wire (not shown) is connected to each of the upper heaters 6.6, and the heat generation is controlled by a control switch 10 disposed on the front operation panel 4, similar to the upper heater 6.6.

The heater mounting portion 12.12 of the reflector includes:
Net shelf support pieces 14, 14, which are made of cut and raised pieces of multiple hooks.
are integrally formed, and an appropriate mesh shelf (not shown) is installed between the mesh shelf support pieces.
can be suspended.

Further, on the lower surface of the reflector plate 11, a sliding metal fitting 15 extending from both ends of the reflecting plate and extending along the heater mounting portion 12 is fixed with a rivet or the like. It is made to be able to slide freely on a guide rod 16 which is formed to hang down along the side wall 9, and as shown in FIG. The guide rod 16 is inserted between the two, resulting in the reflection plate 1
1 moves up and down reliably but does not swing in the left, right, front and back directions.

Of course, the guide rod 16 is fixed and suspended between ears 18, 18 cut and raised at the upper and lower parts of the side wall 9.

Further, the lower heater 7 and the γ reflector 1 are attached to the side wall 9 to which the guide rod 16 hanging down along the side wall 9 is attached.
A notch 19 is enlarged along the guide rod 16 so that a sliding metal fitting 15 extending from both ends of the guide rod 16 can be inserted therethrough.

20 is stretched along the back wall 21 of the open main body 1,
In addition, it is an arm piece made of a metal round bar whose both ends are bent along the side walls 9, 9, and the bent portion 22 is located near the back wall 21, that is, behind the side wall 9. The device is placed in a recess 23 with a notch opening on the side, and its free end 24 is locked to the sliding fitting 15, and is bored into the sliding fitting 15 as shown in FIGS. 2 and 3. Horizontal slit 24
The free end portion 24 is loosely fitted and locked inside.

Therefore, the arm piece 20 is connected to the sliding fitting 15 or the guide rod 1.
6, the road edge portion 24 reciprocates within the horizontally elongated slit 24 when the road edge portion 24 moves up and down along the horizontal slit 24 and rotates around the bent portion 22 which becomes the rotation fulcrum portion. be.

A tension spring piece 25 is tensioned between the hook 26 provided on the side wall 9 at the center of the free end 24 and the bent part 22 of the arm piece 20. The free end portion 24 is always urged upward.

That is, the reflector plate 11 of the lower heater 7.7, which is engaged with the free end portion 24, is always urged upward by a spring.

Reference numeral 27 denotes an operating lever for vertically moving the reflector 11 of the lower heater 7.7 by manual operation.The operating lever has an operating piece 29 installed at one end in a vertically long slit 28 bored in the front panel 4, and the operating lever 27 sequentially moves the reflector 11 of the lower heater 7. The other end engaging portion 30 extends along the side wall 9 and engages with the sliding fitting 15 formed on the reflecting plate 11 of the lower heater 7.7. A slit 24' is formed, and the horizontally long slit is connected to the sliding fitting 15 as shown in FIG.
The free ends 2 of the arm pieces 20 are aligned with the horizontally elongated slits 24 formed in the slits 24 and 24 to form an overlapping state.
4 are engaged with each other in a loosely fitted state.

An operating knob 31 is attached to the one end operating piece 29, and by holding the operating knob and moving it up and down, the operating lever 29
Reference numeral 7 moves up and down, and the sliding fitting 15 that engages with the other end holding portion 30 can be moved up and down, that is, the lower heater γ and the reflecting plate 11 of 7 can be moved up and down.

A vertical portion 32 along the side wall 9 is provided between the operating piece 29 at one end of the operating lever 2γ and the engaging portion 30 at the other end, and a guide groove 33 is provided in the vertical portion. A guide pin 34.3 that can protrude from the side wall 9 is provided in the guide groove.
4 is placed on the top and bottom for drinking.

However, the operating lever 2γ moves up and down along the guide bins 34, 34, and the operating knob 31 attached to the operating piece 29 at one end moves up and down accurately along the front cylinder panel 4. .

Reference numeral 35 designates a display board on the front panel 4 that indicates the vertical movement range of the operating knob 31, and the operating knob 31 is placed on an appropriate drinking station of the eyelid drawn on the display board to indicate the range of vertical movement of the operating knob 31. Lower heater γ.

7, the upper and lower softness can be displayed.

Reference numeral 36 is provided on the vertical portion 32 of the operating lever 27, and prevents the upward biasing force of the operating lever 27 against the tension of the spring piece 25 stretched over the arm piece 20.
This is an articulation device for stopping the T at a predetermined drinking stop, and includes a sawtooth section 37 carved on the end face of the vertical section 32, and a pressing piece 38 provided on the side wall that bites into the sawtooth section with elasticity. It is more intimidating.

Since the present invention is constructed as described above, all operating parts are placed at the front, and the operation can be performed from the front while visually observing the inside of the roasting chamber, and the lower heater can be reliably set in the designated device. Roasting efficiency can be improved by allowing close proximity between the two.

Furthermore, when holding the operating lever, only the fingertips to be operated are brought close to the main unit, so there is no risk of burns because the palm of the hand does not hit the heated main unit, and the operating lever can be moved up and down while maintaining the horizontal position. Since it can be adjusted in different directions, its operability is improved and an electrical open circuit that is extremely easy to handle can be obtained.
