JP2010032115A - Protective cover for door for heating device - Google Patents

Abstract

<P>PROBLEM TO BE SOLVED: To solve a problem wherein for example, when an oven function of a microwave oven is used for a long time, the surface temperature of a door may be increased and contact with the surface of the door of which temperature is increased may cause burns, and thus, it is required to pay attention to burns etc. due to contact with the surface of the door only when the surface temperature of the door is raised. <P>SOLUTION: Since a cover is provided on a door of a heating device, this prevents contact with the door surface of which temperature is raised during use, so as to prevent burns caused by contact with the door surface of which temperature is raised. Since the surface temperature of the door may be increased depending on a use method, the cover has a structure which can be easily attached/detached to/from the door of the heating device so that the cover can be used only when the temperature of the door is increased. To prevent deterioration of design performance of the door when the cover is not attached, the door itself has no specific device and mechanism, and a holding mechanism during attachment is provided in the cover itself. <P>COPYRIGHT: (C)2010,JPO&INPIT

Description

  The present invention relates to a heating apparatus that heats an object to be heated by a heater, a microwave, or the like, and relates to a protective cover for a heating apparatus door against an increase in door temperature.

  In general, a heating device that heats an object to be heated by a heater, a microwave, or the like, for example, a high-frequency heating device is provided with an operation unit such as a heating means on the surface of the device body (for example, see Patent Document 1).

FIG. 8 shows such a high-frequency heating device, and an operation unit 6 for operating a heating means (not shown) is provided on the front surface of the main body of the heating device 2 together with a door 4 for opening and closing the heating chamber 3 with a door handle 4a. Yes, the operation unit 6 is operated to perform various types of cooking.

  With conventional heating devices, the temperature of the door surface may become high depending on the method of use, and there is a risk of burns by touching the door surface. Although it is necessary to pay attention to touching the door when the temperature of the door becomes high, the present invention solves such a problem.

  The present invention solves such problems, and aims to provide a door protection cover for a heating device that prevents a burn caused by touching the door surface by attaching a heat protection cover to the door of the heating device. Is.

  In order to solve the above-mentioned conventional problems, according to the present invention, since a door protection cover against heat is attached to the door of the heating device, it is not possible to directly touch the surface of the door when the temperature is high. Prevent burns from touching.

  Further, by providing a gap through which air passes between the door protection cover and the door surface, and by providing a structure that allows the surface temperature of the door protection cover to be lower than the surface temperature of the door, the surface of the door protection cover Since the temperature can be lower than the door surface temperature, burns can be prevented even when the door surface temperature increases.

  The door's protective cover can be easily removed so that it can be attached only when necessary, such as when the door surface temperature is high or when the frequency of such usage is high. Can be removed.

  In addition, no special attachment / detachment mechanism is provided on the door, and the attachment / detachment mechanism is provided on the door protection cover, so that the design of the entire heating device is not restricted, and the design is particularly good with the door protection cover removed. There is no loss.

  The present invention can prevent burns and the like by attaching a protective cover against heat even when the door surface of the heating device becomes high and there is a risk of burns.

  The first aspect of the invention prevents the burns and the like by attaching the protective cover against the heat by detaching the present invention only when necessary, such as when the door of the heating device becomes hot and may cause a burn. Can do.

  According to a second aspect of the present invention, the protective cover is provided with a structure that allows air to pass between the protective cover and the surface of the door so that the surface temperature of the protective cover can be lower than the surface temperature of the door.

  In the third invention, the protective cover is provided with an attaching / detaching mechanism and the heating device door is attached / detached without providing a special mechanism. A door handle is required to attach the protective cover to the door.

  In the fourth invention, the protective cover has a structure in which the heating chamber can be seen by providing innumerable holes in a range where the heating chamber of the door of the superheater can be seen. A structure that can be washed when water adheres.

Embodiments of the present invention will be described below with reference to the drawings. In this embodiment,
Therefore, the present invention is not limited.

(Embodiment)
1 and 2 are a front view and a side view, respectively, showing a state in which a protective cover according to an embodiment of the present invention is attached to a built-in oven microwave oven.

  As shown in FIG. 1, the built-in oven microwave oven 1 includes a door 4, a door window 4 a, a door handle 4 b, and an operation unit 6. The protective cover 5 is attached to the door 4 so as to be held by the door handle 4b, and has a structure capable of gripping the door handle 4b.

  FIG. 3 is a cross-sectional view of the microwave oven door to which the protective cover 5 is attached. As shown in FIG. 3, the protective cover 5 is attached to the door so as to be attached to the door handle 4b by the attaching / detaching mechanism 5a and the attaching / detaching mechanism spring 5b, and the door 4 is not provided with a special attaching / detaching mechanism. .

  As described above, the present invention relates to a protective cover for a heating device door against an increase in the temperature of the door, and can be applied to a heating device that heats an object to be heated by a heater, a microwave, or the like.
