Abstract

PURPOSE:To always keep a window pane of the door of a cooking device clean without damaging a transparency of the window pane by wiping off adhering oil and the like by a method wherein coating material mainly based on polytitanocarbosiran is applied on an inner surface of the door having the window pane. CONSTITUTION:Water is put in a water pan 9 of a cooking unit, an item to be cooked is placed on a burning net 4, an upper heater 5 and a lower heater 6 are energized to completely grill the cooking item. In this case, although oil and the like adhere to an inner surface of a cooking housing or a door 2, the adhering oil and the like can be completely wiped off due to the fact that a coating film having polytitanocarbosiran having a high heat-resistant characteristic as its major material has been applied. As a result, it is possible to keep the window pane 8 of the door 2 always clean and transparent.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to cooking appliances such as open and open toasters used in general households.

Conventional Technology Conventionally, it has been known that this type of cooker has had its inner wall treated with self-purification or coated with fluorine to improve cleaning efficiency. Nothing had been treated in this way.

Problems to be Solved by the Invention In conventional cookers of this type, when reheating fried foods or grilling fish inside the cooker, scattered oil adheres to the inner surface of the door including the window glass, causing problems during cooking. The problem was that the heat burned it in, making it impossible to remove it even with wiping, making it difficult to see inside or outside through the window glass, and leaving a persistent odor.

In order to solve this problem, an attempt was made to coat the inner surface of the door, including the window glass, with fluorine, but this could not be achieved because the temperature of the fluorine part exceeded 880°C during dry firing, exceeding the heat resistance limit.

The present invention is intended to solve these problems, and it is an object of the present invention to provide a cooking appliance in which oil adhering to the inner surface of the door can be easily wiped off.

Means for Solving the Problem In order to solve this problem, the present invention coats the inner surface of the door including the window glass with a paint mainly composed of polytitanocarbosilane.

Function: Due to this structure, the paint based on polytitanocarpojifusi is non-adhesive, and oils adhering to the inner surface of the door can be easily wiped off. Moreover, the paint mainly composed of polytitanocarbosilane has high heat resistance, and it is possible to provide a robust cooker that will not cause any abnormality even if it is erroneously energized continuously during dry firing.

EXAMPLE Hereinafter, an example of breeding of the present invention will be explained based on the drawings.

In FIGS. 1 and 2, l represents a cooking device body having an opening at the front end. This opening can be opened and closed by a door 2. Inside the cooker 8 formed inside the cooker body 1, a grill 4 is provided near the center, an upper heater 5 is provided above the grill 4, and a lower heater 6 is provided below. are provided respectively, and an upper heater 6 is provided.
A heat reflecting plate 7 is provided above. In addition, the top, both sides, back, and bottom of the inner wall surface of the cooking device 8 and the inner surface of the door 2 (including the window glass 8 attached to the door 2) are each made of polytitanocarposilane as a main material. In particular, the inner surface of the window glass 8 is coated with a transparent undiluted solution without adding any pigment. A paint mainly composed of polytitanocarbosilane (trade name: Tyrannocoat (manufactured by Ube Industries, Ltd.)) has the structure shown below and has excellent thermal stability.

CH.

-S i -CHt - This polytitanocarbosilane is dissolved in a solvent such as toluene or xylene, and coated on the inner wall surface of the cooking device 8 and the inner surface of s2 as described above.

By baking at a temperature of approximately 500° C., good adhesion to the base material and the non-adhesive properties of silicone can be obtained.

In addition, numeral 9 in the figure is a water tray disposed at the lower end of the cooking device 8, and is made of a material with good heat reflection efficiency (for example, a stainless steel plate). Reference numeral 10 denotes an oxidation catalyst type smoke removal member attached to a partial notch of the plate (2) forming the top surface of the cooking device 8, through which the cooking gas is released to the outside. A heat equalizing plate having a plurality of openings is disposed above the subordinate heater 6, and the temperature distribution on the lower surface of the food placed on the grill 4 is made uniform.

Next, the operation of the cooker configured as above will be explained. In the case of grill cooking, water is first poured into the water tray 9, food to be cooked such as fish is placed on the grill 4, and the upper heater is heated. -5
Then, the lower heater 6 is energized to bake. At this time,
Since the oil that is scattered and attached to the heat reflecting plate 7 is heated to 850° C. or higher and thermally decomposed, the heat reflecting effect is maintained forever. Further, oils adhering to the inner surfaces of the cooking device 8 and the door 2 can be wiped off after cooking due to the non-adhesive nature of the coating film mainly composed of polytitanocarbosilane on the surface. In addition, the polytitanocarposifun has high heat resistance, with a temperature of 800°C during grill cooking and a temperature change of 4 when continuously energized.
Can withstand temperatures of 00°C. In addition, the water tray 9
Any oil that falls on the food can be thrown away along with the water after cooking.

Effects of the Invention As described above, according to the present invention, even if scattered oil adheres to the inner surface of the door, it can be easily wiped off. In particular, the door window glass can be kept clean forever by wiping it without impairing its transparency. Moreover, the paint mainly composed of polytitanocarbosilane has high heat resistance, and it is possible to provide a robust cooker that will not cause any abnormality even if it is erroneously energized continuously during dry firing.
