Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a roaster such as a toaster oven.

Conventionally, in Juichi Buntosuku and other machines, the grill installed inside the housing was moved back and forth in conjunction with the door that opened and closed on the front of the housing, but the grill was supported from both sides. Pins are formed to protrude, and these holding pins are inserted into horizontal long holes formed in both side walls of the casing in which the baking chamber is formed.

Therefore, the inside of the baking chamber and the outside thereof communicate with each other through the long holes serving as openings.

With conventional toaster ovens of this type of structure, there are no particular problems when baking for an appropriate cooking time, but if the roasting state continues for a long time due to problems with setting the time switch or failure of the time switch, etc. The following problems arise.

In other words, the structure of the toaster oven is designed to be safe no matter how long the heating element inside the oven is energized, and the toaster oven is designed to be safe even if the heating element inside the oven is energized for a long time. Designed to be as safe as possible.

However, as mentioned above, when the grilling chamber and the outside communicate with each other through an opening such as a long hole, the flame inside the grilling chamber may leak out through the long hole and directly heat the external case, which is extremely dangerous. be.

In particular, when the food to be cooked in the grill chamber becomes carbonized and smoke exits from the elongated hole and burns outside the housing, the combustion temperature is high and the painted parts of the outer case may catch fire, or the painted parts of the outer case may catch fire. The synthetic resin products contained in the product may catch fire and cause a fire.

The present invention has been made in view of these points, and an object of the present invention is to provide a roaster in which the outside of the roasting chamber does not become high temperature.

An embodiment of the present invention will be described based on the drawings.

First, an outer case 1 whose outer surface is painted is provided, a knob 2 made of synthetic resin is attached to the side surface of this outer case 1, and a bottom plate 4 to which legs 3 made of synthetic resin are fixed is attached to the lower surface. ing.

A housing 6 having an opening 5 formed in the front surface is provided inside the outer case 1, and the top and back surfaces of the housing 6 are covered with a reflecting plate 7 to form a baking chamber 8.

Moreover, a rod-shaped heating element 10 is attached to the upper and lower portions of the housing 6 between the side walls 9 by means of sheath heat or the like.

Furthermore, a long hole 1 is provided slightly below the center of the both side walls 9.
1 is installed horizontally.

Next, a grill 12 is provided inside the casing 6, and two support pins 13 that fit into the elongated holes 11 are provided on both sides of the grill 12 so as to protrude outward.

A tension spring 14 is provided on the outside of the casing 6 and has one end locked to the support pin 13 on the front side and the other end locked to the upper back part of the grilling chamber 8. It is always biased backwards.

A support bracket 15 is provided at the lower front of the opening 5, and a door 16 for opening and closing the opening 5 is rotatably attached to the support bracket 15.

A handle 17 is attached to the outside of the upper end of the door 16, and a bracket 18 is formed at the center of the inside.

A door arm 19 formed of a wide plate material is rotatably attached to the bracket 1B, and locking notches 20 and 21 into which the support pin 13 is fitted are formed at the lower edge of the door arm 19.

In particular, the locking notch 20 is always engaged with the support pin 13.

The door arm 19 is formed in a shape that sufficiently covers the elongated hole 10 when the door 16 is closed, and serves as a cover member.

Note that 22 is a timer.

In such a configuration, when the door 16 is opened or closed, the grill 12 also moves back and forth, but in the open state, the door 16 is also biased in the closing direction by the tension spring 14 that pulls the grill 12. The door 16 is maintained in a horizontal position by its own weight.

At this time, the heating element 10 is not energized, so
The door and arm 19 do not need to close the elongated hole 11.

When the door 16 is closed, the grill 12 also moves back and becomes ready for roasting, but at this time the door arm 19 covers the elongated hole 11.

Therefore, even if the roasting time is incorrectly set on the timer 22 and roasting is performed for a long time, the temperature in the roasting chamber 8 becomes high and the object to be roasted becomes flammable. Since the amount of air is limited, oxygen quickly runs out, and even if a flame occurs, it is quickly extinguished.

Furthermore, the flame does not escape from the casing 6, so it is safe.

For this reason, the high-temperature part is limited to the inside of the baking chamber 8, which has been designed with safety in mind, and the coating on the outer case 1 will not burn, and the knobs 2 and legs 3 will not become soft.

In the above embodiment, the door arm 19 was used as a covering member for the elongated hole 11.
A cover member may be provided separately from the door arm 19.

In the present invention, the elongated hole formed to hold the grill grate as described above is provided so as to be covered by the door arm interlocked with the door, so that the inside of the grill chamber can be isolated from the outside air.
As a result, even if the temperature inside the roasting chamber becomes high and the object to be roasted becomes flammable, the elongated hole that opens to the outside is covered, so it will not burn outside the roasting chamber.
As a result, the high-temperature part is limited to only the inside of the firing chamber, which has the effect of not inducing a fire.

Claims (1)

[Claims] 1. Long holes for slidably holding the grill in the front-rear direction are formed on both side walls forming a grilling chamber of a housing with a heating element installed inside and an open front, and the front of the housing is opened and closed. A door is provided, the door and the grill are connected by a door arm, and the door arm is made wide so that when the door is closed, the door arm covers the elongated hole and doubles as a covering member.
