In addition, FIGS. 1 and 4 respectively show the closed state of the front door 20 of the oven 100, and FIGS. 2 and 5 respectively show the open state of the front door 20 of the oven 100. FIG. 3 and FIG. 6 respectively show a state in which the front door of the oven 100 is opened and the net member 30 is removed from the heating chamber HC of the oven 100. In addition, in each figure, two directions orthogonal to each other in a plane parallel to the surface (mounting surface) on which the heating object is placed in the net member 30 are set as the X-axis direction (first direction) and the Y-axis direction (second direction), and the direction perpendicular to the X-axis direction and the Y-axis direction is set as the Z-axis direction (third direction). In the following description, the X-axis direction is set as the left-right direction of the oven 100, the Y-axis direction is set as the front-back direction of the oven 100, and the Z-axis direction is set as the up-down direction of the oven 100. The oven 100 of this embodiment is a heating cooking machine having a net member 30 on which the heating object is placed. As shown in the figures, the oven 100 has a main body 10 with an open front (surface on the -Y direction side) and a front door 20 installed on the front of the main body 10 in an openable and closable manner. The main body 10 and the front door 20 constitute a box-shaped heating chamber HC for heating a heating object, and a net member 30 and a heater 12 are arranged inside the heating chamber HC. The main body 10 is, for example, a shell having an inner surface made of metal, and a foot (support foot) 11 is provided at the bottom of the outer side (outer shell), and a net member 30 is arranged inside. A plurality of heaters 12 are provided inside the main body 10 so as to extend in the left-right direction (X-axis direction). In the case of the present embodiment, as shown in Figs. 4 to 6, one upper heater 12a is provided above the mesh member 30, and two lower heaters 12b to 12c are provided below the mesh member 30, but the number and arrangement of the heaters 12 can be arbitrary. For example, a carbon heater, a quartz tube, a halogen heater, an armored heater, etc. can be used as each heater 12. In addition, a reflective member 13 can be provided inside the main body 10 for efficiently irradiating the heating object on the mesh member 30 with heat rays (e.g., infrared rays) emitted from the heaters 12a to 12c. In the case of the present embodiment, the reflective member 13 is, for example, a metal plate member extending in the left-right direction (X-axis direction), and can include a plurality of reflective surfaces (reflective plates) 13a to 13f. The reflective surfaces 13a to 13b constitute at least a portion of the upper surface (top surface) inside the heating chamber HC, the reflective surface 13a is arranged above the upper heater 12a (on the +Z direction side), and the reflective surface 13b is arranged in front of the upper heater 12a (on the -Y direction side). The reflective surfaces 13c to 13d constitute at least a portion of the lower surface (bottom surface) inside the heating chamber HC, the reflective surface 13c is arranged in front of the lower heaters 12b to 12c (on the -Y direction side), and the reflective surface 13d is arranged below the lower heaters 12b to 12c (on the -Z direction side). In addition, the reflecting surfaces 13e~13f constitute at least a part of the inner surface of the interior of the heating chamber HC, and the reflecting surface 13e is arranged behind the lower heaters 12b~12c (+Y direction side (inside)), and the reflecting surface 13f is arranged between the upper heater 12a and the lower heaters 12b~12c in the up-down direction (Z axis direction). In the examples shown in Figures 4 to 6, the reflecting surfaces 13a, 13b, 13c, 13e of the reflecting member 13 are arranged at an angle and/or curvature so that the heat rays radiated from the heaters 12a~12c are efficiently irradiated to the heating object on the mesh member 30. In addition, the reflecting surfaces 13d and 13f are processed to diffusely reflect the heat rays radiated from the heaters 12a~12c, and specifically, a plurality of protrusions (convex portions) in the shape of quadrangular pyramids are formed. In addition, the reflecting surface 13d may be configured as a part of a tray 14 provided at the lower part of the main body 10 in a manner that allows for removal (loading and unloading). The tray 14 is a member for receiving objects (e.g., bread crumbs) dropped from the heating object placed on the net member 30. The front door 20 has a hinge member at its lower part (e.g., the lower end), and the front door 20 is configured to be able to open and close the heating chamber HC (main body 10) by rotating in the θX direction (rotation direction around the X axis) with the lower end as the center. In addition, the front door 20 may have a handle portion 22, a window portion 23, and an operating portion 24. The handle portion 22 is a portion that the user holds in order to open and close the front door 20, and can be made of a material that is difficult to transmit heat from the heating chamber HC (for example, resin, plastic). The window portion 23 is made of a light-transmitting component so that the user can confirm the inside of the heating chamber HC when the front door 20 is closed (closed state). In the case of the present embodiment, in order to reduce the leakage of heat from the inside of the heating chamber HC to the outside of the oven 100, the window portion 23 is made of a double structure of LowE glass (low-emissivity glass). In addition, the operating portion 24 is a portion operated by the user in order to set and adjust the heating temperature and/or heating time of the heating chamber HC, and can be made of, for example, a button or a dial. The operation unit 24 may also include a display unit (display) for displaying information such as the set temperature of the heating chamber HC, the set time, the measured temperature of the heating chamber HC, the remaining time for heating, and the elapsed time. In addition, when the measured temperature of the heating chamber HC is displayed on the display unit, a sensor for measuring the temperature inside the heating chamber HC may be provided. The net member 30 is a member in which a metal rod is formed into a net shape in a manner capable of carrying a heating object, and the net member 30 can be moved parallel to the front-rear direction (Y-axis direction) (i.e., translated) in accordance with the opening and closing of the front door 20. For example, when the user opens the front door 20, the net member 30 is translated forward (-Y direction) along with the opening action and is pulled out from the inside of the heating chamber HC. On the other hand, when the user closes the front door 20, the net member 30 moves inward (in the +Y direction) in translation with the closing action and is disposed between the upper heater 12a and the lower heaters 12b to 12c in the heating chamber HC. If the net member 30 is translated while the net member 30 is being taken out or put in, the distance between the net member 30 and the main body 10 (for example, the upper heater 12a and the reflecting surface 13a of the reflecting member 13) in the vertical direction can be kept constant during the translation of the net member 30, thereby reducing the possibility that the heating object is caught on the main body 10 while the net member 30 is being taken out or put in. In addition, the oven 100 of the present embodiment is configured to be able to remove the net member 30 from the inside of the heating chamber HC, thereby improving the cleanability of the inside of the heating chamber HC. That is, the oven 100 of the present embodiment is configured to be able to move the net member 30 in translation when taking out and putting in the net member 30, and to be able to easily remove the net member 30 from the inside of the heating chamber HC. In the following, the structure of the mechanism for taking out and putting in the net member 30 in the oven 100 of the present embodiment is specifically described. In the oven 100 of the present embodiment, as shown in the various figures (especially Figures 4 to 6), a shaft member 40, a guide member 50 and an arm member 60 are provided as the mechanism for taking out and putting in the net member 30. In addition, as shown in Figure 3, the net member 30 can be configured to have a mounting portion 31 (first portion), a supported portion 32 and a hook 33. The mounting portion 31 is a portion for mounting the object to be heated. The supported portion 32 is a portion that protrudes from the outer frame of the mounting portion 31 in the left-right direction, is supported by the guide member 50, and is hooked by the top end portion 63 of the arm member 60. The hook 33 is a portion for hooking the net member 30 to the shaft member 40, and a plurality of hooks can be provided in a manner that can be separated in the left-right direction (X-axis direction). The shaft member 40 is made of, for example, a metal rod, and is extended in the left-right direction (X-axis direction) inside the heating chamber HC so as to be hooked to the hook 33 hung on the net member 30. An opening portion 41 extending in the front-rear direction (Y-axis direction) is provided on the inner side surface (surface on the side in the X-axis direction) of the heating chamber HC, and the shaft member 40 is configured to be guided by the opening portion 41 and to be movable in the front-rear direction. In addition, the shaft member 40 is pushed toward the inner side (+Y direction) of the heating chamber HC by a pushing member such as a spring member. The pushing member is arranged between the inner side surface of the heating chamber HC and the outer side surface (outer casing) of the main body 10, and is omitted from the drawings. In addition, from the perspective of the cleanability of the interior of the heating chamber HC, the shaft member 40 is ideally one, but as long as the cleanability can be ensured, it can be two or more. The guide member 50 is composed of a protrusion protruding from the inner side surface of the heating chamber HC toward the center of the heating chamber HC, supports the net member 30 inside the heating chamber HC, and guides the net member 30 so that the net member 30 can translate in the front-rear direction. In the case of the present embodiment, the guide member 50 is composed of a protrusion extending in the front-rear direction (Y-axis direction) on the inner side surface of the heating chamber HC, and more specifically, it can be composed of a plurality of (two) protrusions 51, 52 arranged in a manner of sandwiching the supported portion 32 of the net member 30 from the upper and lower directions (Z-axis direction). Here, the opening portion 41 of the shaft member 40 may be arranged on the inner side surface of the heating chamber HC, and the opening portion 41 may be arranged on the inner side of the heating chamber HC (+Y direction side) relative to the guide member 50. By setting such a configuration, when the net member 30 is removed from the inside of the heating chamber HC, the shaft member 40 extending in the left-right direction across the heating chamber HC can be arranged inside the heating chamber HC by using a spring member or other repelling member, thereby improving the cleanability of the heating chamber HC. The arm member 60 has a top end portion 63 that can be hooked on the supported portion 32 of the net member 30, and is arranged (mounted) on the front door 20 in such a manner that the net member 30 is pulled out from the inside of the heating chamber HC by the opening action of the front door 20. In the present embodiment, the arm member 60 can be configured as a link mechanism, which includes: a plate-shaped first portion 61 mounted on the front door 20; and a plate-shaped second portion 62 having a top end portion 63, which is rotatably mounted on the first portion 61 by a hinge mechanism or the like. The top end portion 63 is formed, for example, by a groove formed in the second portion 62 so that a metal rod constituting the supported portion 32 of the net member 30 passes therethrough, and the metal rod of the supported portion 32 of the net member 30 can be hooked on the supported portion 32 of the net member 30 by passing the metal rod of the supported portion 32 of the net member 30 through the groove. With such a structure, when the user opens the front door 20, the arm member 60 pulls the net member 30 forward (-Y direction) and the net member 30 can be pulled out from the inside of the heating chamber HC. On the other hand, when the user closes the front door 20, the shaft member 40 that is pushed toward the inside of the heating chamber HC by the push member (spring member) pulls the net member 30 inward, so that the net member 30 can be arranged inside the heating chamber HC. Here, as shown in FIG. 4 , when the front door 20 is divided into three equal regions in the vertical direction and defined as the first region R ₁ , the second region R ₂ , and the third region R ₃ from the lower end of the front door 20 , the arm member 60 (the first portion 61 ) can be provided in the second region R ₂ . The second region R ₂ can also be understood as the central region (central portion) of the front door 20 in the vertical direction. By mounting the arm member 60 on the front door 20 in this way, as shown in FIG. 5 , when the heating object is placed on or taken out of the net member 30 with the front door 20 opened (open state), the arm member 60 can be reduced from becoming an obstacle. In the oven 100 of the present embodiment, the top end portion 63 of the arm member 60 is removed from the supported portion 32 of the net member 30, and the hook 33 of the net member 30 is removed from the shaft member 40, so that the net member 30 can be easily removed from the inside of the heating chamber HC as shown in FIG. 3 and FIG. 6. In addition, when the net member 30 is removed, as described above, since the shaft member 40 is arranged inside the heating chamber HC by the elastic member, the inside of the heating chamber HC, such as the lower heaters 12b~12c and the reflection surfaces 13c~13e, can be easily cleaned. That is, the cleanability of the heating chamber HC can be improved. The invention is not limited to the above-mentioned embodiments, and various changes and modifications can be made without departing from the spirit and scope of the invention.
