Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a roaster capable of performing direct roasting and indirect roasting.

Conventionally, there are various types of roasters depending on the purpose of use. Of these, the heat generating part is limited to electric heaters, such as toasters exclusively for sliced bread, toaster ovens that can cook over open flames, so-called toaster ovens that have the same function as gas ovens but have a large capacity, and electric There are heavenly flames, etc. However, the optimal cooking content for each of these methods is limited to some extent; for example, it takes 6 minutes to toast sliced bread in an electric toaster oven or a bit oven toaster. It is impossible to do this with just one model. Another drawback is that the internal temperature distribution is not uniform, which tends to cause uneven cooking.Furthermore, even if the internal volume is large, only one plate can be set for cooking that requires a saucer, making it unusable. There is also the issue of efficiency.

The present invention has been made in view of these points, and it is an object of the present invention to provide a roaster that can be used in a wide variety of cooking applications with a single model.

The present invention enables relatively high-temperature direct-fire roasting of sliced bread, pizza, gratin, etc. using a first roasting chamber provided with a heating element, which is flattened and linked to a door. By providing a grill grate, it is possible to easily take in and out the roasted materials, and by providing a second roasting chamber that communicates with this first roasting chamber through a ventilation passage, a ventilation section is used to draw the roasted materials into and out of the first roasting chamber. The heated air is sent into the second roasting chamber to perform indirect roasting for cooking sponge cakes, kutskies, etc.
Moreover, since the heating is performed using hot air, the temperature distribution inside the oven is made uniform, and even if multiple saucers are provided, as long as there is a gap between them, even roasting can be achieved. be.

An embodiment of the present invention will be described based on the drawings. First, inside an outer case 1 formed by combining a plurality of plate materials, main frames 2 serving as an inner casing are provided facing each other, and a reflective plate is installed slightly below the center of these main frames 2. A partition plate 3 which also serves as a partition plate 3 is provided almost horizontally. Further, between the main frames 2, there are provided a rear reflector plate 4, a waste tray 7 located above the top plate 5, and the bottom plate 6, which can be freely pulled out to the front.
The lower part of the partition plate 3 is a first roasting chamber 8 which is flat and has a small volume, and the upper part of the partition plate 3 is a second roasting chamber 9 which has a large volume. In addition, horizontal grill guide holes 10 are formed in the first roasting chamber 8 portion of the main frame 2;
When viewed from the front, the main frame 2 on the right side is formed with a plurality of openings 11 located above and below the grid guide holes 10, and the main frame 2 on the left side has a baffle plate 12 for guiding airflow upward. A plurality of openings 13 are formed. Further, the main frame 2 located in the second roasting chamber 9 has air guide plates 14 and 15, respectively.
A plurality of openings 16, 17 are formed.

Next, in the first roasting chamber 8, two heating elements 18 made of rod-shaped heaters are installed on the upper and lower sides, and a grilling grate 20 having protrusions 19 projecting on both sides in the central part is installed in the front and back. It is set up so that it can move forward and backward.
Further, in the second roasting chamber 9, saucer supports 22 on which the saucers 21 are placed and fixed are provided in two vertical stages.

On the outside of the main frame 2 on the right side when viewed from the front, there is provided a vertical partition plate 25 that separates the space 23 and the motor storage chamber 24.
A motor 26 is provided which is fixed to the motor housing 5 and located within the motor storage chamber 24, and a fan 28 serving as a blowing section facing the opening 11 is formed on a motor shaft 27 of the motor 26. This fan 2
The air flow generated by the opening 11, the first roasting chamber 8, the opening 13, the space 29 formed by the main frame 2 and the outer case 1,
The opening 16, the second roasting chamber 9, the opening 1
7. The air circulates in the order of the space 23, and such a circulation path is defined as a ventilation path 30.

Next, a door holding plate 31 is fixed to the front lower part of the main frame 2, and these door holding plates 31 have front portions of the first roasting chamber 8 and the second roasting chamber 9. A door 32 for opening and closing the opening is rotatably attached by a support pin 33. A transparent glass 34 is attached to the center of the door 32, and a handle 35 is attached to the upper part.
Furthermore, brackets 36 that project inward are provided on both lower sides of the inner surface of the door 32. Next, one end of an L-shaped operating lever 37 is rotatably attached to the outer surface of the main frame 2 with a pin 38, and a connection between the operating lever 37 and the bracket 36 is provided with pins 39 and 40. They are connected by a link 41 that is rotatably attached.
At the tip of the operating lever 37, there is a floating part 42 formed in an arc centered on the pin 38 and a driving part 43 formed on a radial line centered on the pin 38, forming a substantially L-shape. A continuous slit 44 is formed, and one of the protrusions 19 of the gridiron 20 is fitted into the slit 44.

In addition, an operation panel 4 is provided on the front of the outer case 1.
5 is formed, and this operation panel 45 is provided with a switch 46 for controlling the driving of the motor 26 and a timer setting knob 47 for controlling the time period during which the heating element 18 is energized. This timer also controls the driving time of the motor 26 when the switch 46 is ON.

In addition, 48 is a knob for carrying, and 49 is a leg.

In such a configuration, when the door 32 is opened by holding the handle 35, the operating lever 37, which is connected to the door 32 by the link 41, rotates, but in the initial rotation range, the protrusion 19 is connected to the slit 44. Since the operating lever 37 is fitted into the floating portion 42 of the operating lever 37, only the operating lever 37 rotates. And door 32
After opening considerably, the protrusion 19 comes to fit into the drive part 43, and as the door 32 rotates, the gridiron 20 rapidly advances forward. Therefore, even if the position of the grill 20 is low with respect to the support pin 33 that is the center of rotation of the door 32, the grill 20 will not interfere with the door 32. Further, the saucer 21 is also set arbitrarily with the door 32 open.

The usage conditions vary depending on the content of cooking, but in the case of toast, pizza, gratin, etc., the switch 46 turns off the power to the motor 26, and the timer operation knob 47 powers only the heating element 18. , pound cake, cookie, cupcake, etc., the heating element 18 and the motor 26 are energized at the same time.

Further, in the case of toast etc., since the first roasting chamber 8 is flat and the distance of the heating element 18 to the gridiron 20 is close, roasting is performed using strong heat as direct flame roasting. This state is similar to that of a conventional toaster oven, and is particularly suitable for high-temperature roasting of thin items. Next, in the case of cakes, etc., a circulating air flow is generated by the fan 28 and flows in the ventilation passage 30 as shown by the arrow, but this air flow is heated by the heating element 18 and becomes high temperature, so the second Air heating is performed in the roasting chamber 9. Therefore, even if the saucers 21 are arranged in parallel, there is a gap between them, so that the heated air passes through evenly, and the object to be roasted is heated uniformly over the entire surface. Therefore, even if a larger number of trays 21 are provided, the roasting condition remains the same, and in some cases, it is possible to roast a very thick cake with a single tray 21.

In addition, during implementation, the temperature in the first roasting chamber 8 was 350 to 400°C, and the temperature in the second roasting chamber 9 was 350 to 400°C.
It is desirable that the temperature be around 200℃.

The present invention provides a first roasting chamber in which a heating element is provided as described above, and a second roasting chamber that is communicated with the first roasting chamber through a ventilation passage.
The roasting chamber is divided into two parts inside the warehouse, and a ventilation section is installed to generate an air flow through the ventilation passage.
When using the second roasting chamber, high temperature direct flame roasting can be performed, and when using the second roasting chamber, uniform heating can be performed at medium temperature, making it suitable for a variety of cooking. If the heating element is located lower, the thermal efficiency can be increased, and if the volume of the first roasting chamber is reduced, the direct flame will be even more powerful and roasting will be done quickly. Moreover, even if it is flattened, the roasting material can be easily taken in and out by using a grill grate, and even if multiple trays are installed in the second roasting chamber, which has a large capacity, the main frame will not fit. Since an opening corresponding to each saucer is formed, it is possible to sufficiently uniformly heat the roasted material in each saucer.
