Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a so-called hop-up toaster with a shutter that opens and closes a bread inlet in connection with the lifting and lowering operations of a bread lifting device. The purpose is to provide a time interval between the two operations and to obtain a configuration in which both operations are performed reliably and smoothly using a simple mechanism.

In conventional hop-up toaster with a shutter, when toasting bread, a certain distance is placed between the top of the standard bread and the shutter, and when the hook of the lifting plate is released, the shutter is opened at the beginning of the rise of the bread and the bread is raised. was.

However, when baking bread that is taller than standard bread, such as Yamagata bread, the gap becomes smaller, and the bread protrudes into the input slot before the shutter is completely opened, causing it to get stuck in a part of the shutter and stop rising. An inconvenience has occurred.

Normally, a hop-up toaster is configured to open an automatic switch in conjunction with the lifting operation of the lifting device.
Because the lifting device was not raised sufficiently, the circuit remained closed and heating continued, which could lead to a fire.

The present invention solves the above-mentioned conventional drawbacks, and embodiments of the present invention will be described below with reference to the accompanying drawings.

In the figure, 1 is the outer shell body, 2 is a lowering hand that can be rotated approximately 90 degrees, and 3 is a top plate fixed to the upper surface of the outer shell body 1.

This top plate 3 is provided with a bread inlet 4 and a slot 5, and an engaging portion 7 of a shutter 6 is inserted into the slot 5 and is slidable horizontally.

9 is a lift knob, 10 is a temperature adjustment knob, and 11 is an operation knob for manually opening and closing the shutter 6.

Reference numeral 12 denotes an inner cylindrical body which includes a central heater 13 and side heaters 14, and a reflection plate 15 is attached to the side heaters 14.

One guard 11 of the guards attached to each of the heaters 13 and 14 is formed with a sloped portion 18 and a pan support portion 19 for moving the pan 20 toward the center.

A center bimetal part 21 is arranged near the central heater 13, and the inclined part 18 and the pan support part 19 support the pan 20.
moves to the center heater 13 side, and the center bimetal part 2
1, a certain distance is ensured, and the browning is stable.

22 is a bread tray supported by the lifting plate 23, which is formed by bending a wire rod.
It is located at

Reference numeral 23 denotes an elevating plate, which moves the bread tray 22 up and down.

A frame 24 is fixed to the inner cylindrical body 12 and supports the temperature control rod 25 and the fulcrum portion 26 of the operating rod 34 of the shutter 6.

Reference numeral 27 denotes an operating metal fitting, which has a suppression spring 28, an operating portion 29, and an operating shaft portion 30, and operates in the same manner as the operating rod 34.

Reference numeral 31 denotes a sliding metal fitting, the lower end of which loosely fits into the operating rod 34 and has a leaf spring 32 into which the engaging portion 7 of the shutter 6 is fitted, and which slides guided by the shaft 33 to open and close the shutter 6. .

Next, the operation in the above configuration will be explained.

When the elevating plate 23 is lowered, the bread 20 is lowered and is supported by the bread support portion 19 of the guard 17 above the lowest position of the bread receiver 22.

When the elevating plate 23 is further lowered, the leaf spring 28 is pressed, and the actuating metal fitting 21 and the actuating shaft 34 are rotated in the opposite direction of the arrow.

The rotation of the operating shaft 34 causes the shutter 6 to slide via the sliding fitting 31, thereby closing the bread inlet 4.

The elevating plate 23 is locked in a lower position by a hook (not shown).

In this state, the heaters 13 and 14 are energized, and when the center bimetal 21 detects the completion of roasting, the elevating plate 23
is released and begins to rise.

At the beginning of the rise of the elevating plate 23, the contact portion 35 of the elevating plate 23 rotates the actuating portion 29 in the direction of the arrow.

That is, the operating metal fitting 21 rotates, the shutter 6 slides in the direction of the arrow via the operating rod 34 and the sliding metal fitting 31, and the bread inlet 4 is opened.

After this, the bread receiver 22 comes into contact with the lower end surface of the bread 20 and lifts the bread 20.

As is clear from the above description, the toaster of the present invention has an actuating part for closing the shutter at the lowest position of the elevating plate, and the bread is raised after the actuating part completes the operation. This prevents the inconvenience that the pan gets stuck in a part of the shutter and stops rising, and the opening/closing operation of the shutter and the raising and lowering of the pan can be performed smoothly.
