Description

  The present invention relates to a cooking pot with a lid for cooking a large amount of food at once, more specifically, because the lid weight of the cooking kettle is heavy, a lid opening / closing drive device is installed on the side of the cooking kettle, The present invention relates to a cooking pot with a lid in which a lid and a lid opening / closing driving device are connected by a lid opening / closing arm and the lid is lifted by the lid opening / closing driving device.

As described in Japanese Patent No. 3718614, a cooking pot with a lid having a lid body that is open at the top and a lid that covers the top opening of the barrel body is widely used. In this case, in the cooking kettle that allows cooking inside the kettle while pressurizing or depressurizing the lid, the lid must be able to withstand the pressure. The body weight is very heavy. When the weight of the lid is too heavy to move manually, or when automation is performed, a lid opening / closing drive device is installed, and the lid body is opened and closed by the lid opening / closing drive device.

To open and close the lid with the lid opening / closing drive device, install the lid opening / closing drive device on the side of the hook body, connect the lid body and lid opening / closing drive device with the lid opening / closing arm, The lid is moved up and down by a driving device. As a method for raising and lowering the lid body, Japanese Patent No. 3718614 discloses a cooking pot for vertically raising and lowering the lid body, and providing a fulcrum that rotates about a horizontal axis at the top of the lid opening and closing drive device, The lid opening / closing arm is connected to the fulcrum, and the lid opening / closing arm is rotated about the horizontal axis of the fulcrum, so that the lid body connected on the front side of the lid opening / closing arm is flipped obliquely. Has been done.

When the lid is opened and closed, the operation amount of the lid opening and closing drive device is detected by a limit switch or the like, and it is detected that the lid has been moved to a predetermined position, and the raising or lowering of the lid is stopped. At this time, if the detection of the stop in the lid opening / closing drive device has not been correctly performed due to a shift in the detection position, the stop position of the lid is shifted.

When the lid is raised, there is no significant effect even if the lid stop position is slightly deviated. However, if the lid stop position is deviated when the lid is lowered, it may have a serious effect. If the lid stop position is set so that it slightly passes from the original stop position, the lid opening / closing drive device will further push down the lid even after the lid reaches the top surface of the hook body. Therefore, the hook body is pressed from above by a force exceeding the normal load. For example, the cooking pot body is often supported from the left and right by a rotary shaft so that it can be tilted and tilted by rotating it back and forth around the rotary shaft. Because the strength of the rotary shaft of the hook is weak compared to other parts, if a force stronger than usual is repeatedly applied from above the hook body, damage such as deformation may occur at the hook rotary shaft. there were.

An embodiment of the present invention will be described with reference to the drawings. The figure shows a cooking kettle embodying the present invention, which has a large capacity for cooking a large amount of ingredients at once. FIG. 1 is a front view showing an operation state in which the lid body 4 is flipped up. FIGS. 2 and 3 show examples of connection between the lid body and the lid opening / closing arm and the movement of the lid opening / closing arm. FIG. 3 is an assembly view of the lid and the lid opening / closing arm, and FIG. 3 is a cross-sectional view of FIG. In the case of FIG. 3, the left side of the figure is a state where the lid body 4 is lifted by the lid opening / closing arm 5, and the right side of the figure is a state where the lid opening / closing arm 5 is further lowered after the lid body 4 is placed on the hook body 1. Is shown.

The cooking pot with lid shown in FIG. 1 has a pot body 1 in the center and a stand 3 on the left and right of the pot body 1. The hook main body 1 and the gantry 3 are connected by a hook rotating shaft 2, and the hook main body 1 is configured to be able to rotate in the front-rear direction around the hook rotating shaft 2. The hook body 1 is a container having an open top, and a lid 4 for closing the opening is installed on the top of the hook body. When the cooking pot is a pressure pot or a vacuum pot, the lid 4 must be able to withstand pressure, and the lid 4 is made of a thick material. In that case, the weight of the lid 4 becomes heavy, and it may be difficult to open and close only by human power. Therefore, a lid opening / closing drive device 11 is provided right next to the cooking pot, and the lid body 4 is opened / closed by the lid opening / closing drive device 11. A fulcrum that rotates about the horizontal axis is provided on the top of the lid opening / closing drive device 11 side mount, and the lid opening / closing drive device 11 rotates the fulcrum. The base side of the lid opening / closing arm is connected to this fulcrum, and the tip side of the lid opening / closing arm is connected to the lid body 4.

The lid opening / closing drive device 11 and the lid body 4 are connected by the lid opening / closing arm 5, and the lid opening / closing arm is rotated by the horizontal axis of the fulcrum by the lid opening / closing drive device 11. Rotate around. Therefore, the lid connected to the distal end side of the lid opening / closing arm 5 moves up and down. In FIG. 1, the state in which the lid body 4 is lowered by the lid opening / closing drive device 11 is represented by a solid line, and the state in which the lid body 4 is flipped up by the lid opening / closing drive device 11 is represented by a broken line.

The lid opening / closing arm 5 is connected to the lid body 4 on the distal end side, and a lid body connecting member 12 for connecting to the lid opening / closing arm 5 is provided on the upper side of the lid body 4. The lid connecting member 12 has a columnar shape standing vertically from the lid 4 and is provided with two lid part connecting holes 7 penetrating the lid connecting member 12. The lid opening / closing arm 5 has an inverted U-shaped cross section so that the lid opening / closing arm 5 can be put on the lid connecting member 12, and the connection between the lid opening / closing arm 5 and the lid connecting member 12 is a recess of the lid opening / closing arm 5. The projection of the lid connecting member 12 is fitted into the top.

The arm connection hole 6 is provided at a position corresponding to the cover body connection hole 7 of the cover opening / closing arm 5. When the cover body 4 and the cover opening / closing arm 5 are connected, the arm connection hole 6 and the cover The connecting shaft 8 is inserted in a state where the body part connecting holes 7 are aligned, and fixed so that the connecting shaft 8 does not come off. At this time, the arm connecting hole 6 provided in the outer lid opening / closing arm 5 is adapted to the diameter of the connecting shaft 8, but the lid connecting hole 7 provided in the inner lid connecting member 12 is A long hole with a longer vertical diameter is used.

The lid opening / closing drive device 11 that drives the lid opening / closing arm 5 includes a lid opening limit switch 9 that is detected when the lid 4 is raised to the upper end position, and a lid 4 when the lid 4 is lowered to the top of the hook body 1. The lid closing limit switch 10 to be detected is provided, and the operation of the lid opening / closing drive device 11 is stopped by detection by the limit switch. Furthermore, the limit switch for detecting when the lid is closed is doubled, and the lid lower limit switch 13 is installed so that the lid opening / closing drive device 11 stops operating even when the lid lower limit switch 13 is activated. I have to.
The lid closing limit switch 10 and the lid lower limit switch 13 are different in the height position of the lid 4 to be detected. The lid closing limit switch 10 is a position where the lid 4 reaches the hook body 1 and the lid lower limit. The limit switch 13 further lowers the lid opening / closing arm 5 from the limit switch 13 so that the connection shaft 8 is detected at a position partway down the long hole of the lid body portion connection hole 7. Therefore, normally, the lid opening / closing drive device 11 is stopped at the position detected by the lid closing limit switch 10, and the lid lower limit switch 13 is activated by the lid closing limit switch 10. It is assumed that it did not stop.

In the case of FIG. 3, the lid 4 is lifted by the lid opening / closing arm 5 on the left side of the drawing, and the lid opening / closing arm 5 is further lowered after the lid 4 is placed on the hook body 1 on the right side of the drawing. Indicates the state. When the lid body 4 is lifted, the lid opening / closing arm 5 supports the upper inner surface of the lid body portion connection hole 7 on the upper surface of the connection shaft 8 and lifts the lid body 4. When the lid body 4 is lowered, the lid body 4 is supported by the connecting shaft 8 until the lid body 4 is placed on the hook body 1. However, when the lid body 4 is placed on the hook body 1, the lid body 4 is lowered. When the lid opening / closing arm 5 is further lowered, the connecting shaft 8 is separated from the upper inner surface of the lid portion connecting hole 7 as shown on the right side of FIG.

The descent stop of the lid opening / closing arm 5 in the normal state is performed by the operation of the lid closing limit switch 10. However, when the lid closed limit switch 10 does not stop because the detection position of the lid closed limit switch 10 has shifted, the lid opening / closing arm is further lowered even if the lid 4 is lowered to the upper part of the hook body 1. 5 will be lowered. At this time, if the lid body connecting hole 7 is vertically long, after the lid body 4 is lowered to the upper part of the hook body 1, only the lid opening / closing arm 5 is lowered while the lid body 4 remains. This does not mean that the lid opening / closing arm 5 pushes down the lid 4.

When the lid opening / closing arm 5 is further lowered and the lid lower limit switch 13 is activated, the lid opening / closing arm 11 is stopped from being lowered by the lid opening / closing drive device 11. For this reason, even if the lid opening / closing arm 5 does not stop at the position of the lid closing limit switch 10, the lid body 4 does not push down the hook body 1 strongly, and damage to the hook rotating shaft 2 can be prevented. .

4 and 5 relate to another embodiment. In this embodiment, contrary to the previous embodiment, the lid connecting member 12 is a concave portion, and the lid opening / closing arm 5 is a convex portion. The lid opening / closing arm 5 and the lid connecting member 12 are connected by fitting the convex portion of the lid opening / closing arm 5 into the concave portion of the lid connecting member 12. When the connecting shaft 8 is attached, the lid part connecting hole 7 of the lid connecting member 12 that is the outside is a round hole, and the arm part connecting hole 6 of the lid opening / closing arm 5 that is the inside is a vertically long slot. .

Also in the case of FIG. 5, the lid 4 is lifted by the lid opening / closing arm 5 on the left side of the drawing, and the lid opening / closing arm 5 is lowered after the lid 4 is placed on the hook body 1 on the right side of the drawing. Indicates the state. When lifting the lid body 4 in this shape, the lid body 4 is lifted by supporting the connection shaft 8 fixed to the lid body connection member 12 on the lower inner surface of the arm portion connection hole 6. When the lid body 4 is lowered, the connection shaft 8 is supported by the arm connecting hole 6 until the lid body 4 is placed on the hook body 1, but when the lid body 4 is placed on the hook body 1, the lid body 4 is supported. When the lid opening / closing arm 5 further descends from there, only the lid opening / closing arm 5 is lowered as shown on the right side of FIG.

Also in this case, when the lid 4 is closed, the lid closing limit switch 10 that operates when the lid 4 is lowered to the hook body 1 detects the stop position of the lid 4 and the lid opening / closing arm 5 Stop the operation. When the lid closing limit switch 10 is not stopped and the lid opening / closing arm 5 continues to lower after the lid 4 reaches the hook body 1, only the lid opening / closing arm 5 is lowered. Also in this case, a lid lower limit switch 13 is provided to detect at a position corresponding to the case where the connecting shaft 8 of the lid opening / closing arm 5 is lowered to the middle of the arm connecting hole 6, and the lid opening / closing arm 5 is provided with the lid lower limit. When the limit switch 13 is lowered, the operation of the lid opening / closing drive device 11 is stopped. The position detected by the lid lower limit switch 13 is within the range of the arm connecting hole 6 which is a long hole. When the lid opening / closing arm 5 is stopped at the detection position of the lid lower limit switch 13, the lid opening / closing arm is stopped. Even if 5 does not stop at the original stop position, the lid main body 1 is not pressed by the lid opening / closing arm 5.

If the lid opening / closing arm 5 has a shape that sandwiches the lid connecting member 12 when the lid opening / closing arm 5 and the lid connecting member 12 are connected, the arm connecting hole 6 of the lid opening / closing arm 5 on the outside is If the hole diameter matches the diameter of the connecting shaft 8 and the lid connecting member 12 has a shape that sandwiches the lid opening / closing arm 5, the lid connecting portion 7 of the lid connecting member 12 on the outside is connected to the connecting shaft 8. The hole diameter should match the diameter. In this way, the connecting hole on the outer side has a hole diameter that matches the diameter of the connecting shaft 8, so that the connecting shaft 8 can be fixed to the lid connecting member 12 or the lid opening / closing arm 5. If the connection shaft 8 can be fixed, the lid part connecting hole 7 or the arm part connecting hole 6 which is the inside can be made long in the vertical direction.

By making the lid part connecting hole 7 or the arm part connecting hole 6 into a long hole, even if the stop position of the lid opening / closing arm 5 is shifted and goes down beyond the stopping position, the lid body 1 is moved by the lid opening / closing arm 5. There is no holding down. Further, if the lid lower limit switch 13 is provided at that position and the lowering of the lid opening / closing arm 5 is stopped by the lid lower limit switch 13, the hook body 1 is not pressed down at the stop position by the lid lower limit switch 13. Damage to the rotary shaft 2 can be prevented.

The present invention is not limited to the embodiments described above, and many modifications can be made by those having ordinary knowledge in the art within the technical idea of the present invention.
