  Drawing 2 is a side view showing the state where the door of the cooking-by-heating machine concerning one embodiment of the present invention was closed. As shown in the figure, the handle 9 of the heating cooker 1 according to the present embodiment has a book in one direction parallel to the surface plane of the front surface of the door 7 when the door 7 closes the cooker body 2. In the embodiment, the handle portion 8 is positioned at a position where the axis 11 connecting the handle 9 mounting position of the door 7 and the handle portion 8 is substantially perpendicular to the door 7 when viewed from the lateral direction.

  Moreover, FIG. 3 is a side view which shows the state which fully opened the door of the heating cooker concerning one Embodiment of this invention. As shown in the figure, the handle 9 of the heating cooker 1 in the present embodiment has a handle 9 of the door 7 when viewed from the same direction as when the door 7 is closed when the door 7 is fully opened. The handle portion 8 is positioned at a position where the axis 11 connecting the attachment position and the handle portion 8 is substantially horizontal to the door 7.

  Thus, the heating cooker 1 according to the present embodiment has the door 11 with the axis 11 connecting the handle 9 mounting position of the door 7 and the handle portion 8 when the handle 9 is in a state where the door 7 closes the cooker body 1. The handle portion 8 is positioned at a position substantially perpendicular to the door 7, and when the door 7 is fully opened, the axis 11 that connects the handle 9 mounting position of the door 7 and the handle portion 8 is approximately the door 7. The handle 8 is movable so as to be positioned respectively at horizontal positions. With such a configuration, when developing the cooking device 1, it is not necessary to secure the length of the handle 9 in the lower space of the door 7, and the restriction on the height of the heating chamber 3 can be suppressed.

  Further, when the door 7 is in the closed state, the handle 9 mounting surface of the door 7 faces the user side, so that the user can visually recognize the handle 9 and the door 7 is fully opened. In this case, even if the back surface of the door 7 faces the user side, the handle portion is positioned so that the axis 11 connecting the handle 9 mounting position of the door 7 and the handle portion 8 is substantially horizontal to the door 7. 8 can be positioned so that the handle 9 can be seen even when the user closes the door 7, and the door 7 can be easily opened and closed regardless of whether the door 7 is closed or open. It can be set as the easy-to-use heating cooker 1 which can be performed.

  Next, an example of a mechanism for moving such a handle will be described. FIG. 4 is a cross-sectional view seen from the side with the door closed on the line AA in FIG. As shown in the figure, the handle 9 of the heating cooker 1 in the present embodiment has a handle portion 8 formed by a rod-shaped gripping rod 9a, and a right handle holding portion 9b for holding the right side of the gripping rod 9a. The left handle holding portion 9c holds the left side of the gripping rod 9a, and one ends of the right handle holding portion 9b and the left handle holding portion 9c are rotatably attached to the upper portion of the door 7. An upper right support plate 12a is integrally attached to the right handle holding portion 9b, and an upper pulley 13 is integrally attached to the upper right support plate 12a. Since the upper pulley 13 is integrally attached to the right handle holding portion 9b that is rotatably attached to the door 7, the handle 9 can also be rotationally driven by the rotation of the upper pulley 13. A lower pulley 14 is disposed inside the door 7 at the lower right side of the door 7, and the lower pulley 14 is integrally fixed to one end of the lower support plate 15. The other end of the lower support plate 15 protrudes from the door 7 and is fixed to the main body 2. Therefore, the lower pulley 14 does not rotate. The upper pulley 13 and the lower pulley 14 are respectively connected by a wire 16, and the wire 16 is detoured by a guide 18 in order to avoid a structure of the door 7 such as a radio wave leakage prevention plate 17. The guide 18 is attached to the door 7 so that the attachment position can be freely moved so that the tension of the wire 16 can be adjusted.

  FIG. 5 is a cross-sectional view seen from the side with the door closed on the BB line of FIG. As shown in the figure, a spring holder 19 is rotatably attached to the door 7 on the upper left side of the door 7 which is opposite to the handle mounting position on the door 7. The spring holder 19 is integrally attached to the upper left support plate 12b, and the upper left support plate 12b is integrally attached to the left handle holding portion 9c of the handle 9, respectively. A spring 20 is wound around the spring holder 19, and the handle 9 is always urged by a spring force so that the axis connecting the handle 9 mounting position and the handle portion 8 is substantially perpendicular to the door 7. ing. Therefore, since the spring holder 19 is integrally attached to the left handle holding portion 9c that is rotatably attached to the door 7, the handle 9 can also be driven to rotate as the spring holder 19 rotates.

  The operation of the handle 9 configured as described above will be described with reference to FIGS. When the handle 9 which is the handle portion 8 of the handle 9 is gripped and pulled forward, the door 7 is opened. As shown in FIG. 4, the lower pulley 14 is fixed to the lower support plate 15 so that it cannot be rotated by the lower support plate 15, so that the wire 16 is wound around the lower pulley 14 as the door 7 is opened. . With this winding, the upper pulley 13 connected by the wire 16 is also drawn in the winding direction of the wire 16 to the lower pulley 14. Further, since the upper pulley 13 is rotatably attached to the door 7, the upper pulley 13 is also rotated by the amount that is pulled. Accordingly, the upper right support plate 12a fixed integrally with the upper pulley 13 and the right handle holding portion 9b fixed integrally with the upper right support plate 12a are also rotated, and as a result, the handle 9 is moved.

  6 is a cross-sectional view seen from the side with the door fully open along the line AA in FIG. 1, and FIG. 7 is a cross-sectional view seen from the side with the door fully opened along the line BB in FIG. is there. As a result, as shown in FIGS. 4 and 5, when the door 7 is in a state where the cooker body 1 is closed, the axis 11 that connects the handle 9 mounting position of the door 7 and the handle portion 8 is However, as shown in FIGS. 6 and 7, when the door 7 is fully opened, the handle 9 mounting position of the door 7 and the handle 8 are connected. It will move so that the handle part 8 may be located at a position where the axis 11 is substantially horizontal to the door 7.

  On the other hand, when closing the door, if the handle 7 is closed by holding the grip bar 9a which is the handle portion 8 of the handle 9 and closing the door 7 to the main body 2 side, the lower pulley 14 as shown in FIGS. Is fixed to the lower support plate 15 so as not to rotate, so that the wire 16 is detached from the lower pulley 14 as the door 7 is closed. At this time, as shown in FIGS. 5 and 7, the spring holder 19 is fixed to the upper left support plate 12b, and the handle 9 is always set to the handle 9 mounting position by the spring force of the spring 20 wound around the spring holder 19. By urging the axis connecting the handle portion 8 so as to be substantially perpendicular to the door 7, the extra length of the wire 16 that comes off as the door 7 is closed is the aforementioned spring force. As a result, the upper pulley 13 rotates and is rewound onto the upper pulley 13. With these series of actions, the heating cooker 1 according to this embodiment is configured such that when the handle 9 is in a state where the door 7 closes the cooker main body 1, the axis 11 connecting the handle 9 mounting position of the door 7 and the handle portion 8. The handle portion 8 is positioned at a position substantially perpendicular to the door 7, and when the door 7 is fully opened, the axis 11 connecting the handle 9 mounting position of the door 7 and the handle portion 8 is relative to the door 7. Thus, the handle portions 8 are movable so as to be positioned at substantially horizontal positions.

  By the means as described above, the cooking device 1 according to the present embodiment has the handle 9 within the movable range of the door 7 from the state where the door 7 closes the cooking device body 2 to the state where the door 7 is fully opened. According to the open state of the door 7, the position of the handle portion 8 becomes substantially horizontal with respect to the door 7 from the position where the axis connecting the handle 9 mounting position of the door 7 and the handle portion 8 is substantially perpendicular to the door 7. It is possible to sequentially vary the range up to the position. That is, the handle 9 sequentially changes the angle of the axis connecting the handle attachment position to the door 7 and the handle portion 8 according to the amount of the wire 16 wound around each of the upper pulley 13 and the lower pulley 14 depending on the degree of opening and closing of the door 7. It is moved by the link moving means.

  FIG. 8 is an explanatory view showing the state of the handle in each open / close state of the door. As shown in the figure, according to such a configuration, as the handle 9 opens and closes the door 7, the axis 11 connecting the handle 9 mounting position and the handle portion 8 becomes substantially perpendicular to the door 7. Since the position is sequentially changed in a range from a position to a position that is substantially horizontal with respect to the door 7, it is not necessary for the user to take a posture of forcing the wrist even when opening and closing the door 7, and the natural door 7. Thus, the usability of the heating cooker 1 can be further improved. In addition, in the heating cooker 1 having such a configuration, if the grip bar 9a of the handle 9 is configured to be rotatable with respect to the right handle holding portion 9b and the left handle holding portion 9c, the user can use the handle portion 8 as a handle. Even if the gripping rod 9a is tightly gripped, even if the axis 11 connecting the handle 9 mounting position and the handle portion 8 is variable according to the opening and closing of the door 7, the change in angle can be absorbed by rotation, so that it is more convenient to use. improves.

  In addition, as apparent from FIG. 8, the cooking device 1 according to the present embodiment has a lower end portion of the door 7 attached to the cooking device body 2, and the door 7 is closed from the front opening of the cooking device body 2. It moves between the state parallel to the floor 21. The link movable means described above is such that the position of the handle portion 8 is such that the axis 11 connecting the handle 9 mounting position of the door 7 and the handle portion 8 is always parallel to the floor surface 21 as the door 7 is opened and closed. Is variable. With such a configuration, the handle 9 is always parallel to the floor surface 21 in any open state, and even when the door 7 is fully opened, both the door 7 and the handle 9 are both floor surfaces 21. Can be parallel to The handle portion 8 of the handle 9 is always present in the field of view of the user standing on the front surface of the cooker body 2 regardless of the open / closed state of the door 9. Since the door 7 can be opened and closed naturally, the usability of the heating cooker 1 can be further improved. In addition, since the handle 9 becomes parallel to the door 7 when the door 7 is fully opened, the lower fulcrum of the main body 2 can be further lowered regardless of the height of the handle 9, so that the interior height D is sufficiently secured. Therefore, a large space in the cabinet can be secured. In addition, even if this structure attaches the door 7 to the upper end part of the cooker main body 2, and the handle 9 is attached to the lower end part of the door 7, it can show | play the same effect.

  FIG. 9 is a side view showing a state where the door is fully opened and a cooking dish is placed on the door. As shown in FIG. 9, the cooking device 1 of the present embodiment has the lower end portion of the door 7 attached to the cooking device body 2, the door 7 is parallel to the floor 21 in the fully opened state, and the door 7. A space is formed above the door 7 and the handle 9 in the fully opened state. According to such a configuration, when the door 7 is fully opened, the handle 9 is also parallel to the floor surface 21, so that not only the surface of the door 7 but also the surface of the handle 9 is a cooking dish 22 such as a square dish. It can be secured enough as a space to take out. And when putting in and out the cooking pan 22 in the heating chamber 3, it can be performed after it is once placed on the door 7, so that the usability of the heating cooker 1 can be further improved.

  The clearance between the handle 7 and the handle 9 of the handle 9 is secured so that the user's operation finger can enter when the door 7 is closed, while the door 7 is being opened / closed, and when the door 7 is opened. If it is necessary, more specifically, if it is 15 mm to 60 mm, good usability can be obtained. When the gap dimension is smaller than 15 mm, it is difficult for the user's finger to enter, and the finger may be caught when the gap dimension changes during opening and closing. On the other hand, if the gap size exceeds 60 mm, the cooking device itself becomes large, and the handle 9 protrudes abnormally from the door 7 and is difficult to use. Of these, 20 mm to 40 mm is the best gap size, and if it is within such a range, further improvement in usability and better design can be imparted to the cooking device.

As described above, according to the present embodiment, the same effect can be obtained with a configuration different from that of the first and second embodiments. It is to be noted that by integrating such link movable means so as to constitute either the left or right handle holding part, it is not necessary to provide the movable means on the other side, so that the manufacturing can be simplified. It is also possible to provide such link movable means on both the left and right handle holding portions. With this configuration, the operation can be ensured. For example, even if one of the movable means breaks down, the handle can be moved by the other movable means. Can be improved.

Embodiment 4 FIG.
The heating cooker 1 in the present embodiment is different in the structure for moving the handle 9 in each of the above-described embodiments. Different parts will be described below. 13 is a sectional view seen from the side with the door corresponding to FIG. 4 in the first embodiment closed, and FIG. 14 is a side view seen from the side with the door corresponding to FIG. 6 in the first embodiment fully opened. FIG. In addition, the same code | symbol is attached | subjected to the structure similar to Embodiment 1, and the description is abbreviate | omitted. In FIG. 13, the upper right support plate 12a is integrally attached to the right handle holding portion 9b of the handle 9 at the upper portion of the door 7, and the upper roller 28 is integrally attached to the upper right support plate 12a. Since the upper roller 28 is rotatably attached to the door 7, the handle 9 can also be rotated. A lower roller 29 is disposed in the door 7 at the lower right side of the door 7. The lower roller 29 is integrally attached to one end side of the lower support plate 15. The other end side of the lower support plate 15 is provided with a main body attachment portion, and the other end side protrudes from the door 7 and is fixed to the main body 2. Has been. Therefore, the lower roller 29 does not rotate. The upper roller 28 and the lower roller 29 are connected by two connecting plates 30.

  The operation of the handle 9 having such a configuration will be described. The door 7 is opened when the gripping rod 9a which is the handle portion 8 of the handle 9 is grasped and pulled toward the front. However, since the lower roller 29 is fixed to the lower support plate 15 so as not to rotate, the door 7 is opened. Therefore, the connecting plate 30 is inclined in the direction in which the door 7 opens. According to this operation, the distance of the connecting portion between the upper roller 28 and the lower roller 29 of the connecting plate 30 changes, but since the length of the connecting plate 30 is constant, this distance can be obtained by rotating the rotatable upper roller 28. Let the change absorb. Since the upper roller 28 is rotatably attached to the door 7, when the connecting plate 30 rotates the upper roller 28 to absorb the change in the distance of the connecting portion, the upper roller 28 is moved to the upper right support plate 12 a and the right handle. Since the holding part 9b is fixed integrally, the result handle 9 is rotated according to the opening / closing operation of the door. The operation of closing the door 7 toward the main body 2 by grasping the grip portion 9a of the handle 9 operates in reverse to the above-described operation. As a result, the handle 9 is always on the floor surface regardless of the open state. Even when the door 7 is fully opened, both the door 7 and the handle 9 can be parallel to the floor surface.

  As described above, even if the movable means of the handle 9 as in the present embodiment is used, the same effect can be obtained with a configuration different from the above-described embodiments. In the present embodiment, the right handle holding portion 9b is provided with a movable means for moving such a handle 9, but it goes without saying that the left handle holding portion 9c may be provided.
