Embodiment 1 FIG.
FIG. 1 is an overall perspective view of a heating cooker 100 according to the first embodiment. 2 is a cross-sectional view taken along the line XX of FIG. FIG. 3 is a schematic diagram showing the inside of the heating cooker 100 according to the first embodiment. 4 is a cross-sectional view taken along the line YY of FIG. FIG. 5 is a schematic diagram of the heating cooker 100 showing that the positions of the placement unit 10 and the heating means 30 of the heating cooker 100 according to Embodiment 1 are variable.

  As shown in FIG. 1, the heating cooker 100 includes a main body 1 whose front surface is open and a door 2 that covers the opening of the main body 1. The door 2 is a member having a handle 2a and is attached to the main body 1 so as to be rotatable. For example, the user can take out a member provided inside the main body 1 by grasping the handle 2 a and pulling out the door 2 to the front side of the main body 1.

  As shown in FIGS. 2 to 4, a heating chamber 5 is provided inside the main body 1. As shown in FIG. 4, a placement unit 10, a heating unit 30, and a shielding plate 40 are provided inside the heating chamber 5. The heating means 30 is provided behind the heating chamber 5 with respect to the placement unit 10. For this reason, even if the heating means 30 is damaged, it is possible to prevent the broken pieces of the heating means 30 from falling on the article to be heated 20. Therefore, it is possible to provide a heating cooker that does not cause discomfort to the user as compared with the prior art and has good workability. Details of the mounting unit 10, the heating unit 30, and the shielding plate 40 will be described later.

  As shown in FIG. 4, a focal point 50 </ b> F <b> 1 is defined inside the main body 1. A focal point 50F2 is defined on the horizontal line passing through the focal point 50F1 and on the back side of the main body 1 with respect to the focal point 50F1. Thereby, an ellipse 60V having the focal points 50F1 and 50F2 as a focal point is formed, and a substantially elliptical heating chamber 5 having an opening in the front in a side longitudinal sectional view of the main body 1 is formed. That is, the heating chamber 5 including an arc shape of an ellipse 60V in the side surface longitudinal sectional view of the main body 1 is formed. The inner wall surface 5a of the heating chamber 5 is made of, for example, a material (for example, aluminum) that reflects light introduced into itself.

  In addition, when the heating chamber 5 has an elliptical shape in a side longitudinal sectional view of the main body 1, the heating chamber 5 becomes a closed space, and even if the door 2 is pulled out to the front side of the main body 1, It will not be possible to put in and out 20 mag. For this reason, the heating chamber 5 needs to be formed so that the article to be heated 20 and the like can be taken in and out. Therefore, for example, it is desirable to configure the inner wall surface 5a provided on the front side of the heating chamber 5 so that the outside of the heating chamber 5 communicates with the inside of the heating chamber 5 with the door 2 opened.

  The placement unit 10 is a member for placing the article to be heated 20, and is configured, for example, by arranging rod-like members in a lattice shape. Although the arbitrary shape can be employ | adopted for the to-be-heated material 20, for example, suppose that it is a box-shaped thing like FIG. A heating unit 30 is provided on the back side of the heating chamber 5 with respect to the mounting unit 10. The heating means 30 is composed of, for example, a heat radiation type heater (glass tube heater) having a light source. The heating means 30 is provided so as to extend in the left-right direction of the heating chamber 5 inside the heating chamber 5. A shielding plate 40 is provided between the article to be heated 20 and the heating means 30.

  The shielding plate 40 is made of a material that does not reflect or transmit the light emitted from the heating unit 30. That is, the shielding plate 40 functions so that the light emitted from the heating means 30 and introduced into itself does not reach the back surface of the article to be heated 20. For example, the shielding plate 40 is made of a glossy metal such as aluminum that reflects light emitted from the heating unit 30. Further, for example, the shielding plate 40 is made of a material having good heat storage properties such as ceramic that stores heat by being emitted from the heating means 30. The shielding plate 40 is provided, for example, so that the vertical center of the shielding plate 40 is located on a horizontal line passing through the focal points 50F1 and 50F2.

  Here, the properties of the ellipse will be described with reference to FIG. When the point on the circumference of the ellipse 60V is the point P, the sum of the distance between the focal point 50F1 and the point P and the distance between the focal point 50F2 and the point P is constant. In general, an ellipse has a property of being directed toward the other focal point when light is emitted from one focal point as a light source. For this reason, when the inner wall surface 5a is formed of a reflecting member and the light source is provided at the focal point 50F2, the light emitted from the light source goes toward the focal point 50F1. In the first embodiment, using such an elliptical property, a part of the object to be heated 20 is provided at a position including the focal point 50F1, the heating unit 30 is provided at the focal point 50F2, and the light is emitted from the heating unit 30. The light is guided to the object to be heated 20 without leakage.

  Hereinafter, the path 60R of light emitted from the heating unit 30 of the first embodiment will be described. As shown in FIG. 4, the light emitted from the heating means 30 is reflected by the inner wall surface 5a and guided to the focal point 50F1, and the object to be heated 20 is heated. Note that the light path 60R shown in FIG. 4 is illustrated for convenience of description, and is not limited to the illustrated path.

  As described above, in the heating cooker 100 according to the first embodiment, the heating chamber 5 has a shape including an arc shape of an ellipse 60V in the longitudinal sectional view of the main body 1, and a part of the placement unit 10. Is located at the focal point 50F1, and the heating means 30 is located at the focal point 50F2. For this reason, the light emitted from the heating means 30 is reflected by the inner wall surface 5a and guided to the focal point 50F1, and the object to be heated 20 is heated. Therefore, the heating efficiency of the article to be heated 20 can be improved.

  A shielding plate 40 is provided between the article to be heated 20 and the heating means 30. For this reason, it can suppress that the back surface of the to-be-heated material 20 assumed that the heat of the heating means 30 is most transmitted is locally heated. Therefore, the to-be-heated material 20 can be heated evenly, and burning can be suppressed.

  In addition, it is desirable that a mark indicating an optimum (preferred) position where the article to be heated 20 is provided is provided on the upper surface of the placement unit 10. Here, the optimum position is, for example, a position indicating at least one of the center of the object to be heated 20 and the focal point 50F1, and is appropriately determined according to the shape of the object to be heated 20. Further, the mark refers to, for example, an optimum region where the object to be heated 20 is provided can be distinguished from other regions.

  For example, the mark applied to the placement unit 10 is such that the color of the optimal position on the top surface of the placement unit 10 where the article to be heated 20 is provided is different from the other areas on the top surface of the placement unit 10. Is. Further, for example, the mark applied to the placement unit 10 is a character or symbol indicating the optimum position where the article to be heated 20 is provided displayed on the upper surface of the placement unit 10. Further, for example, the mark applied to the placement unit 10 is a convex shape with the upper surface of the placement unit 10 positioned at an optimal position where the article to be heated 20 is provided protruding upward. Further, for example, the mark applied to the placement unit 10 is a concave shape in which the upper surface of the placement unit 10 located at an optimal position where the article to be heated 20 is provided is recessed downward.

  Moreover, although the example which prescribes | regulates the focus 50F2 on the back surface side of the main body 1 rather than the focus 50F1 on the horizontal line which passes the focus 50F1 was demonstrated, it is not limited to this. For example, the ellipse 60V may be formed by defining the focal point 50F2 on the back side of the main body 1 with respect to the mounting unit 10 and above the horizontal line passing through the focal point 50F1, and the back side of the main body 1 with respect to the mounting unit 10 The ellipse 60V may be formed by defining the focal point 50F2 below the horizontal line passing through the focal point 50F1. Even if the focal point 50F2 is defined in this way, the light emitted from the heating means 30 provided at the focal point 50F2 is reflected by the inner wall surface 5a and guided to the focal point 50F1, and the article to be heated 20 is heated.

Here, when the focal point 50F2 is defined on the back side of the main body 1 with respect to the placement unit 10 and above the horizontal line passing through the focal point 50F1, the place where the heating means 30 is provided also moves upward. Accordingly, it is desirable to move the position of the shielding plate 40 upward. Thereby, it can suppress that the back surface of the to-be-heated material 20 is heated intensively.
Further, when the focal point 50F2 is defined on the back side of the main body 1 with respect to the placement unit 10 and below the horizontal line passing through the focal point 50F1, the location where the heating means 30 is provided also moves downward. It is desirable to move the position of the shielding plate 40 downward. Thereby, it can suppress that the back surface of the to-be-heated material 20 is heated intensively.

  Further, as shown in FIG. 5, at least one position of the placement unit 10 and the heating unit 30 may be variable in at least one of the vertical direction and the front-rear direction of the heating chamber 5. In this case, it is necessary to change the focal points 50F1 and 50F2 with the movement of the placement unit 10 and the heating means 30, so that the shape of the ellipse 60V changes and the shape of the heating chamber 5 also changes.

  Moreover, although the YY cross-sectional shape of the heating cabinet 5 of FIG. 1 was demonstrated to the substantially elliptical shape, it is not limited to this. For example, the XX cross-sectional shape of the heating chamber 5 in FIG. In this case, for example, the placement unit 10 and the heating unit 30 are provided at positions that match in the front-rear direction of the heating chamber 5 and are different in the left-right direction of the heating chamber 5. Thus, it is not necessary to form the inner wall surface 5a of the main body 1 so that the outside of the main body 1 communicates with the inside of the heating chamber 5, and the inner wall surface 5a of the main body 1 can be formed into an elliptical shape. Therefore, the heating efficiency of the article to be heated 20 can be improved.

  Moreover, in the above description, although the example provided with the door 2 which covers the front side opening of the main body 1 was demonstrated, it is not limited to this. The left side surface of the main body 1 or the right side surface of the main body 1 may be opened, and the door 2 may be provided so as to cover the opening. In this case, even when the YY cross-sectional shape of the heating chamber 5 of FIG. Therefore, the heating efficiency of the article to be heated 20 can be improved.

  Moreover, in the above description, although the example which provides a part of to-be-heated object 20 in the focus 50F1 was demonstrated, it is not limited to this. For example, you may provide a part of mounting part 10 in the focus 50F1. Even in such a configuration, the light reflected from the upper inner wall surface 5a out of the light emitted from the heating means 30 passes through the inside of the object to be heated 20 and is introduced into the mounting portion 10, so that The heating efficiency of the heated object 20 can be improved.

  Moreover, you may make the reflectance in the inner wall surface 5a provided in the position facing the back surface of the heating means 30 among the inner wall surfaces 5a in the heating chamber 5 lower than the reflectance in the other inner wall surface 5a. As a method of reducing the reflectance on the inner wall surface 5a, for example, the light reflected from the reflecting plate 70 is formed by coating the reflecting material on the inner wall surface 5a in black, or configuring the reflecting material on the inner wall surface 5a with a low reflectance. There is a method of projecting the inner wall surface 5a to the front of the heating chamber 5 so as not to enter the heating means 30. In this way, it is possible to reduce the possibility that the heating means 30 will be damaged due to heat caused by reflection. Therefore, the lifetime of the heating means 30 can be extended.

  Moreover, although the example which provided a part of to-be-heated object 20 in the focus 50F1 and provided the heating means 30 in the focus 50F2 was demonstrated, it is not limited to this. For example, the heating means 30 may be provided at the focal point 50F1, and a part of the object to be heated 20 may be provided at the focal point 50F2. Even if comprised in this way, the light radiate | emitted from the heating means 30 is reflected by the inner wall face 5a, is guide | induced to the focus 50F1, and the to-be-heated material 20 is heated. Therefore, the heating efficiency of the article to be heated 20 can be improved.

A part of the light emitted from the heating means 30b is reflected by the inner wall surface 5a and guided to the focal point 50F1, and the object to be heated 20 is heated. Thus, only a part of the light emitted from the heating means 30a and 30b is directed to the focal point 50F1.

  As described above, in the heating cooker 100 according to the second embodiment, the heating means 30a and 30b are provided at positions that are different in the front-rear direction of the heating chamber 5 and coincide with each other in the vertical direction of the heating chamber 5, and the focal point 50F2.

For this reason, it can suppress that the one part area | region of the to-be-heated object 20 located in the focus 50F1 among the to-be-heated objects 20 is heated locally. Therefore, the to-be-heated material 20 can be heated evenly, and burning can be suppressed.

  In the above description, the example in which the heating means 30a and 30b are provided at the same position in the vertical direction of the heating chamber 5 has been described.
