[Industrial applications]

 The present invention relates to a toaster body switch structure, and in particular, a toaster in which a switch is turned on when a knob is pressed down.

[0002]

[Prior art]

 A toaster is a device that inserts sliced bread into the equipment and bake it by electric heat. In this toaster, for example, an elongated hole for inserting sliced bread is formed in the upper part of the equipment body, and an elevating plate supporting the lower part of the bread is moved downward in the equipment body so that it can move up and down. It is energized and can be operated from the side of the main body of the equipment, and the heating section with heaters is arranged on the left and right sides of the lower part of the long hole with this elevating plate in between. The heating part is provided with a heat reflection plate facing the pan.

Therefore, when the pan is inserted into the long hole, the lower part of the pan is supported by the lift plate, and then the knob connected to the lift plate is pressed down from the side of the main body of the device to lock the pan, and the switch is turned on to turn on the heater. When the bread heats up and both sides of the bread are baked to the desired degree, the lock is released and the lift plate is pushed up by the spring force, causing the bread to protrude from the long hole. The switch has a structure in which a switch operation piece made of an insulator formed on a part of the knob that moves up and down makes a pair of switch contact pieces fixed in the device body contact each other.

[0004]

[Problems to be solved by the device]

 However, according to the conventional toaster, when the knob connected to the lift plate is pressed down, the insulator of the switch operation lever integrally connected to the knob brings the pair of switch contact pieces fixed inside the device body into contact with each other. Because of the structure, the switch does not turn ON unless the insulator contacts the switch contact piece accurately.

Normally, the knob is guided up and down along a slit formed on the side surface of the device body, but depending on the state of depression of the knob, the switch operation lever fluctuates and does not come into accurate contact with the switch contact piece. Sometimes. Therefore, there is a drawback that the switch is not turned on or the switch contact piece is damaged.

In view of this, the present invention provides a body switch structure for a toaster in which the switch operating lever for contacting the switch contact piece descends without wobbling to ensure the ON operation of the switch contact piece.

[Means for Solving the Problems]

 The toaster body switch structure according to the present invention is configured such that the lifting body is connected to a lifting plate for placing a pan that is arranged to be able to move up and down below a long hole formed on the top surface of the equipment body, and the lifting body is a spring. Is urged through the guide rod so as to be able to move up and down, and the elevating body is connected with a pressure reducing lever and a switch operating lever. Further, the switch operating lever has an insulator, and the insulator is lowered toward a switch contact piece made of an elastic body fixed in the main body of the device to tilt one of the switch contact pieces to bring them into contact with each other. In the toaster in which the heating section is energized by means of the switch connection, a guide body provided with a guide groove for fitting the switch operation lever is provided inside the device body immediately below the switch operation lever. And characterized by being arranged with.

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. As shown in Fig. 1, a long hole 2 for inserting sliced bread is opened in the top surface of the toaster box-shaped device body 1, and the long hole 2 is sandwiched between the left and right sides of the device body 1. Partition plates 3 and 3 are arranged, and heating units 4 and 4 are arranged at the front and rear. The heating part 4 is equipped with a heater such as a nichrome wire or an infrared lamp.

Vertical guide elongated holes 5 and 5 are formed in the partition plates 3 and 3, and both ends thereof are inserted to engage the elevating plate 6, and the elevating plate 6 is below the elongated hole 2 and is a heating unit. It traverses the inside of the device main body 1 so as to be vertically movable between 4 and 4. A cylindrical elevating body 7 is connected to one end of the elevating plate 6, and the elevating body 7 is fitted to a guide rod 8 erected in the equipment body 1. A coil spring 9 is wound around the guide rod 8 to constantly urge the lifting body 7 upward.

A pressing lever 10 is horizontally connected to the lifting body 7, and the pressing lever 10 projects from a guide elongated hole 11 formed on one side surface of the device body 1, and a knob 12 is attached to an outer end portion thereof. A switch operating lever 13 is horizontally connected to the elevating body 7 so as to face the pressure reducing lever 10, and an insulator 14 having a substantially triangular cross section is attached and fixed to the end of the switch operating lever 13. Below the insulator 14, a pair of switches 16 and 16 having a pair of switch contact pieces 15 and 15a made of an elastic body are arranged in parallel in the device body 1 at a predetermined distance.

As shown in FIGS. 2 and 3, the switches 16 and 16 are fixed by projecting to a switch case 17 fixed in the device body 1, and the guide body 18 projects from the switch case 17 so that the switches 16 and 16 It is in parallel with 16. A guide groove 19 is formed along the center line in the guide body 18, and switch contact pieces 15a, 15a are arranged to face each other with the guide groove 19 interposed therebetween. The switch case 17 is connected to a power supply connection cord (not shown), and is electrically connected to a heater arranged in the heating section 4.

The switch operating lever 13 is fitted in the guide groove 19 and moves up and down. Therefore, slopes 19a, 19a are formed on the upper side of the guide groove 19 so that the switch operating lever 13 can be guided therein. Further, when the switch operating lever 13 is guided by the guide groove 19 and descends, the insulator 14 interrupts between the switch contact pieces 15a, 15a and tilts the switch contact pieces 15a, 15a toward the switch contact pieces 15, 15 side. . Therefore, the insulator 14 is arranged so that the top of the triangular cross section faces downward.

Although not shown, a trigger mechanism is provided which locks the elevator plate 6 when the elevator plate 6 is lowered to the inside of the device body 1 to the maximum extent and releases the lock when the bread is baked. It is common for the mechanism to have an adjusting knob that sets the degree of baking of the bread to the desired degree and rotate it to adjust the desired degree of baking.

Next, the operation of the above embodiment will be described. When the sliced bread is inserted into the slot 2, the lower portion of the bread is supported by the lift plate 6. Then, when the knob 12 is pressed down, the pressing lever 10 and the lift plate 6 are lowered against the force of the coil spring 9 and locked at a predetermined position.

When the lift plate 6 is lowered by depressing the knob 12, the switch operation lever 13 is lowered and guided to the guide groove 19 of the guide body 18, as shown in FIGS. 3 (A) to 3 (B). The insulator 14 contacts the switch contact pieces 15a, 15a and tilts toward the switch contact pieces 15, 15 so that the switch contact pieces 15, 15a come into contact with each other in order to tilt them toward the switch contact pieces 15, 15. The switches 16 and 16 are turned on. Therefore, power is supplied to the heaters of the heating units 4 and 4 to heat the pan P.

When the bread P is baked to a desired degree, the lock that locks the lifting plate 6 is released, the lifting body 7 is lifted by the force of the coil spring 9, and the switch operating lever 13 is also lifted to disconnect the edge. Since the body 14 releases the pressing force of the switch contact pieces 15a, 15a, the elasticity of them causes the contact between the switch contact pieces 15, 15a to be released and the energization to stop, so that the bread P can be picked out from the long hole 2 at a predetermined level. Exposed at height.
