Description

[Detailed description of the invention] [Purpose of the invention] (Industrial application field) The present invention relates to a toaster oven, and includes a main frame forming a roasting chamber and an upper case member covering the upper and rear sides of the main frame. The present invention relates to a structure that prevents flames from coming out from a ventilation hole formed in an upper case member in a toaster that roasts food in a roasting chamber.

(Prior art) In conventional toaster ovens, a space is formed between the roasting chamber and the upper case member so that the heat in the roasting chamber is not conducted to the upper case member of the outer case as much as possible. A structure was adopted in which louver-shaped heat dissipation holes were formed in the upper case member.

(Problems to be solved by the invention) With the structure of the conventional toaster oven described above, the toaster oven may cause the toaster oven to malfunction due to incorrect operation of the switch such as setting the roasting temperature or roasting time, or by roasting the oil-based toaster to a temperature higher than the limit temperature of the toaster oven. There was a problem in that the flames could burn and the flames could come out from the vents in the outer case, creating a dangerous situation.

Looking at this phenomenon experimentally, we found that when the material to be cooked is roasted, the oil first gasifies and becomes oxygen-deficient, and this gas is formed on both sides of the main frame that forms the roasting chamber. Gas flows into the space between the main frame and the outer case through gaps in the roasting chamber, such as through the guide holes of the grill or the joints of the main frame members, and gas accumulates in this space. The material to be cooked continues to burn slightly, and if the electric heating element continues to be energized in this burning state, a gas explosion will occur, and the flame will come out of the roasting chamber through the guide hole in the main frame and touch the main frame. It was confirmed that gas ignited in the space between the exterior case and flames coming out from the ventilation holes of the exterior case.

The present invention was created in view of the above problems, and the space formed between the main frame forming the roasting chamber and the upper case member of the outer case covering this main frame,
To provide a toaster oven in which a portion of the upper case member that communicates with the ventilation hole is partitioned, and there is no risk of gas accumulated in the outer space of the roasting chamber being ignited and flames escaping from the ventilation hole. .

(Means for Solving the Problems) The toaster oven of the present invention has two plates on both sides facing each other, each side having a guide hole that guides the grill grates so that they can move forward and backward, and the back side of the toaster oven is closed with a reflective plate. an exterior case comprising a main frame forming a baking chamber; an upper case member having an upper surface portion that covers the upper surface side of the main frame; and a rear surface portion forming a ventilation hole and covering the rear side of the main frame;
an electric heating element disposed in the roasting chamber,
an upper heat shield plate that protrudes from the upper surface plate portion of the main frame and has a tip abutted on the upper surface portion of the upper case member;
a rear heat shield plate that is fixed to the back surface of the reflector plate and whose tip is in contact with the back surface portion of the upper case member;
a pair of side heat shields, the tips of which are in contact with the upper surface of the upper case member, the rear edges of which are in contact with the back surface of the upper case member, and which abut against both side plates of the main frame, respectively; A ventilation hole is provided in the rear surface of the upper case member, and a space is formed between the main frame and the upper case member by the upper heat shield plate, the rear heat shield plate, and the side heat shield plates. It is characterized by being separated from the part that communicates with the.

(Function) The toaster oven of the present invention is formed between the main frame and the upper case member of the outer case, which form a roasting chamber with the upper heat shield plate, the rear heat shield plate, and the side heat shield plates. The space is separated from a part that communicates with a ventilation hole formed on the back surface of the upper case member, and the flames coming out of the guide hole of the grill grate in the roasting chamber are collected in the part that communicates with the ventilation hole of the outer case.

In addition, 16 is an outer case, and this outer case 16
is constructed in the shape of a housing by an upper case member 17 and end plates 18 and 19. The upper case member 17 is composed of an upper surface part 21 that covers the upper side of the main frame 1 and a back surface part 22 that is bent downward from the rear of the upper surface part 21 and covers the back side of the main frame 1. A louver-shaped ventilation hole 23 is formed in the upper part of this back part 22. Further, the opening/closing door 20 is attached to a front opening formed by the upper case member 17 and both end plates 18 and 19 so as to be openable and closable, and is configured to open and close the front of the roasting chamber 2. Further, a see-through portion 24 through which the inside of the roasting chamber 2 can be viewed is formed in the opening/closing door 20.

The main frame 1 is covered with the exterior case 16, and a space 25 is formed between the outside of the main frame 1 and the exterior case 16. Further, a timer switch, a cord reel, etc. are arranged between the side plate 4 at one end of the main frame 1 and one end plate 18. Further, a side heat shield plate 26 is provided on the inner surface of the other end plate 19.

The material to be cooked placed on the gridiron 27 in the roasting chamber 2 is roasted by the heat generated by the electric heating element 11. By roasting the material to be cooked, the oil contained in the material to be cooked is gasified, and the gas is passed through the guide hole 28 formed in the main frame 1 or the gap between the joint between the main frame 1 and the reflecting plate 5. It flows out into the space 25 between the main frame 1 and the upper case member 17 outside the roasting chamber 2. When the material to be cooked is burned in the roasting chamber 2 and the gas ignites and explodes, flames exit from the guide hole 28 to the space 25 outside the roasting chamber 2. At this time, the space 25
Since the part of the upper case member 17 that communicates with the ventilation hole 23 is partitioned by the upper heat shield plate 10, the rear heat shield plate 30, and the side heat shield plates 15 and 26, There is no possibility of ignition by the gas accumulated in the exposed part, and no flame will come out from the vent hole 23 to the outside of the exterior case 16.

Note that a louver-shaped ventilation hole may also be formed in the rear part of the upper surface part 21 of the upper case member 17 of the exterior case 16, located in a partitioned part of the space part 25.

Note that by forming the upper heat shield plate 10 integrally with the reflection plate 5 of the main frame 1, the number of parts can be reduced.
