Description

[Detailed Description of the Invention] This invention relates to an electric cooking device such as a toaster oven.

Conventionally, this type of electric cooking appliance has been constructed as shown in FIGS. 1 to 3.

That is, inside the main body case 1, a baking chamber 3 with a front opening is formed by the housing 2.

The casing 2 consists of opposing inner walls 4 and 5 and a reflecting plate 6 suspended between these inner walls 4 and 5 on the rear and upper sides.

A control device built-in chamber 9 is provided on the right side of the roasting chamber 3 in which control devices such as a heater changeover switch 7 and a timer 8 are installed.

A cooling device 7L10 is formed on the wall surface of this control device built-in chamber 9 to prevent a rise in temperature inside the chamber.

A door 11 for opening and closing the front opening of the grilling chamber 3 is provided, and a grilling grate 12 that moves forward and backward in conjunction with the opening and closing of the door 11 is installed between the inner walls 4 and 5, and Heating elements 13 and 14 are provided above and below the gridiron 12.

A diffusion plate 17 in which a plurality of circular holes 15 and elongated holes 16 are formed is attached above the lower heating element 13 among these heating elements 13 and 14.

This diffusion plate 17 has the function of dispersing the heat of the heating element 13 in the vicinity of the grilling grate 12 and making the temperature distribution in the grilling chamber 3 uniform.

In such a configuration, when the heating elements 13 and 14 are energized, the temperature inside the baking chamber 3 increases, but since the diffuser plate 17 is made evenly on the left and right sides, the heat generation distribution is somewhat constant.

However, since there is a control device built-in chamber 9 on the right side of the baking chamber 3, which is designed to prevent the temperature from rising due to the cooling holes 10, the temperature on the right side of the baking chamber 3 tends to be low.

Therefore, there is a drawback that the temperature distribution within the combustion chamber 3 is not uniform.

This invention was made in view of the above points, and the purpose of this invention is to obtain an electric cooker that can equalize the temperature distribution within the roasting chamber.

This idea consists of a casing forming a grilling chamber with a front opening, a control equipment built-in chamber located on one side of the grilling chamber and having a plurality of cooling holes communicating with the outside air, and an opening in the front of the casing. A door that opens and closes, a grill installed between the inner walls of the housing, heating elements located above and below the grill, and a diffusion plate provided above the heating element below. , a notch is formed in a corner of the diffuser plate on the back side on the side of the control device built-in chamber.

Therefore, even if there is a low-temperature control equipment built-in room on one side of the grilling chamber, there is a cutout in the diffusion plate that covers the top of the heating element, so the amount of heat directed to the grill on the control equipment built-in room side will increase. When viewed from the inside of the grill, the internal temperature distribution is uniform, and in particular, the temperature on the grill is uniform throughout.

An embodiment of this invention will be explained based on FIGS. 4 and 5.

Components that are the same as those described with reference to FIGS. 1 to 3 are designated by the same reference numerals, and description thereof will be omitted.

In this embodiment as well, the diffusion plate 18 is provided above the lower heating element 13 as described above, but a notch 19 is formed in the back of the diffusion plate 18 on the control equipment built-in chamber 9 side. has been done.

Moreover, cooling holes 23, 24, and 25 are formed in the back surface 20, bottom surface 21, and top surface 22 of the control equipment built-in chamber 9.

In such a configuration, since a convection phenomenon occurs in the control device built-in chamber 9 through the cooling holes 23, 24, and 25 formed on three sides, the inside thereof is cooled, and the heater changeover switch 7
Even if the temperature inside the baking chamber 3 rises, the temperature of the timer 8, power cord (not shown), etc. is kept below a certain level, and the various control devices described above are thermally protected.

When the heating elements 13 and 14 are energized, the temperature inside the baking chamber 3 rises, but since there is a notch 19 in the diffusion plate 18 provided above the lower heating element 13, this part Heat is not diffused and more heat reaches the upper part of the gridiron 12 than other parts.

Therefore, the temperature distribution within the baking chamber 3 is made uniform.

In other words, the area in the grilling chamber 3 that requires uniform temperature distribution is the space above the grill 12, and even if the calorific value of the heating elements 13 and 14 is constant, the space above the grill 12 The temperature distribution in the space is made uniform by the presence of the notch 19 in the diffusion plate 18.

This idea is designed to control the diffusion plate when the baking chamber equipped with the heating element is adjacent to the control equipment chamber with high cooling efficiency, and the heating element is equipped with a diffusion plate. Since a notch is formed in the inner corner of the equipment-containing chamber, it is possible to equalize the temperature distribution inside the roasting chamber when the heating element is energized, thereby making it possible to maintain a constant roasting condition in each part. It has the following effects.
