Description

[Detailed description of the invention] Industrial application field This invention is a toaster oven, etc. that can heat food containing oil and fat by applying a coating with a self-purifying function inside the cooking chamber. This relates to a heating cooker.

BACKGROUND ART A conventional cooking device of this type has a structure as shown in FIG. 4, for example. That is, a coating having a self-purifying function is directly applied to the side wall 3 of the substantially box-shaped inner casing 2 forming the cooking chamber 1, and the heater 4 that heats the cooking chamber 1 and the energization of this heater 4 are controlled. It was equipped with a control device 5 to

Problems to be Solved by the Invention In such a conventional configuration, the coating that has a self-purifying function applied to the side wall 3 is mainly made of a glassy base material with an oxidation catalyst added.
Also, since the baking temperature of the coating is high, the side wall 2
As the base material, aluminum-treated steel plates, etc., which have a high aluminum basis weight and are thick, have been mainly used. This has led to a significant increase in costs. In addition, this type of self-purifying coating is mainly black in color and the coating is thick, so
Most of the heat from the heater 3 will be absorbed, and as a result, it will take longer for the temperature of the coating to rise, and the amount of heat applied to the food will be reduced accordingly. It takes a long time to cook when heating for a short time,
Furthermore, since the amount of heating on the side wall 2 side of the food is particularly reduced, there is a problem in that the quality of cooking is extremely poor due to uneven heating. In addition, since it takes a long time for the temperature of the coating part to rise, there is a negative effect due to a reduction in the amount of heating of the food being cooked.Especially in the case of a device equipped with an automatic toast roasting device, it is necessary to set the roasting time on the circuit. This is difficult, leading to an increase in the cost of the circuit, and requires heating for a considerable period of time in order for the self-purification process to actually be effective. Furthermore, since the self-cleaning coating is applied directly to the side wall 2, the control device 4 is adversely affected by heat, and serviceability is also poor.

This invention solves these problems,
It is an object of the present invention to provide a heating cooker that has a self-purifying function that has little adverse effect on the food to be cooked or a control device, is inexpensive, and has good serviceability.

Means for Solving the Problems In order to solve the above problems, the present invention includes an inner plate member coated with a coating agent having a self-purifying function, and this inner plate member is made of an ultra-thin plate with a raised edge on the outer periphery. is formed into a substantially U-shape, and is attached to the inner wall with an engaging pawl provided on the inner plate member, with a gap formed by the edge stand on the inner wall of the cooking chamber.

Effect According to the above configuration, since the inner plate member is formed into an extremely thin plate and approximately U-shaped with the minimum necessary area,
It is inexpensive, and the temperature rise due to heat absorption from the heater saturates quickly, so there is little effect of uneven heating on the food being cooked.Moreover, the inner plate member is a separate part, and it is not connected to the inner wall of the cooking cabinet. Since there is a slight gap, there is little thermal influence on the control device, and serviceability is also good.

Embodiment Hereinafter, an embodiment of the present invention will be described based on the accompanying drawings. In FIGS. 1 to 3, reference numeral 11 denotes a cooking compartment having a heater 12, and this cooking unit 11 is formed into a substantially box shape by an inner casing 13 made of aluminum-treated steel plate or the like. 14 is the heater 1
This control unit includes a changeover switch 15 for controlling energization of 2, a timer 16, an automatic toast roasting device 17, and the like. Reference numeral 18 denotes an inner plate member formed in a substantially U-shape using an aluminized steel plate made of an ultra-thin plate of about 0.3 mm, for example, and the outer circumference of this inner plate member 18 has a diameter of about 1.5 mm.
A raised edge portion 19 of a height is provided, and an inner wall 20 is provided with
By applying a coating agent made by adding a thermal decomposition catalyst to a phosphate-based inorganic heat-resistant paint to a thickness of 100 μm to 200 μm by low-temperature baking, it has a self-cleaning function, and the rear surface 21 has a positioning claw. 22, and the front part of the edging part 19 is provided with an engaging pawl 23 provided with a cut-out to prevent it from coming off. The inner plate member 18 has the positioning claw 22 inserted into the insertion hole 25 provided in the back surface 24 of the inner casing 13, and the engaging claw 23 provided in the side wall 26 of the inner casing 13. The cooking chamber 1 is engaged with the square hole 27.
1, and has a slight gap between it and the inner casing 13 due to the raised edge part 19. Note that the shape of the inner plate member 18 is such that it is easy to be hit by oil droplets flying from cooking food, and the shape of the inner plate member 18 is such that it is easy to be hit by oil droplets that fly from cooking food, and the shape of the inner plate member 18 is such that it can
It is limited to the range that can be easily seen through 8.

Reference numeral 28 denotes a door that opens and closes the front opening of the cooking cabinet 11, and this door 28 is connected to a grill 29 on which food to be cooked is placed via a metal link 30.

As is clear from the above configuration, the inner plate member 18
is formed of an extremely thin plate with the minimum necessary area, and the coating agent that has a self-purifying function can be made thin and the heat mass is small, so the temperature rise of the inner plate member 18 due to heating by the heater 12 is short-lived. As a result, there is only a slight reduction in the amount of heat applied to the food to be cooked, so there is little negative impact on the quality of the cooking. Furthermore, even with automatic roasting equipment that uses a CR timer, etc., where the cooking time can only be corrected between the first and second toasting times when toast is continuously roasted, the amount of heating of the food will not decrease much. The time can be easily set, and since there is a slight air layer between the inner plate member 18 and the inner casing 13, there is little thermal influence on the control unit 14.

In addition, since the temperature of the inner plate member 18 rises quickly, the self-purifying function works in a short time, resulting in an improvement in the purifying ability. Furthermore, the cost of materials is reduced, and the installation method is simple, simply by inserting each pawl of the inner plate member 18 into the pawl holes of the inner housing 13, making the installation process simple and requiring no separate parts for installation. Therefore, it can be obtained at a low cost and can also improve serviceability.

Effects of the Invention As is clear from the above embodiments, according to the heating cooker of the present invention, a coating agent having a self-purifying function is applied to the inner plate member formed of an extremely thin plate in a substantially U-shape, and Since the plate members are attached to the inner wall of the cooking chamber with a slight gap, the temperature of the inner plate members increases rapidly due to heating by the heater, and as a result, there is only a slight negative effect on the food being heated due to a reduction in the amount of heat. As a result, the quality of cooking can be improved, and the self-purification ability can also be improved. Furthermore, the air layer provided between the inner panel members and the inner wall of the cooking chamber reduces the effect of heat on the control unit, and it is also inexpensive in terms of construction and materials, and has good serviceability. It is.
