  Hereinafter, an embodiment of the present invention will be described with reference to the drawings. In addition, the same code | symbol was attached | subjected to the same structure as the prior art example.

(Embodiment 1)
1 is a side view of the main part of the cooking device according to Embodiment 1 of the present invention when the door is closed, FIG. 2 is a side view of the main part of the cooking device when the door is opened, and FIG. 3 is a perspective view of the cooking device. It is. FIG. 4 is a diagram showing a resistance region of the damper when the door of the cooker is opened and closed, and FIG. 5 is a drag characteristic diagram with respect to the stroke of the damper of the cooker.

  The feature of the present invention is that the impact force is buffered before the door 4 is closed and before the door 4 is opened and reaches the terminal end in the opening / closing operation of the door 5 for taking in and out the article 3 to be heated in and out of the heating chamber 2. It is to configure a damper.

  Hereinafter, it demonstrates in detail according to an Example.

  In FIG. 1 thru | or FIG. 3, the cooking device 1 mounts the to-be-heated material 3 heated by an electric heating or a high frequency in the heating chamber 2 arrange | positioned inside, and opens and closes the door 4 with which the opening part of the heating chamber 2 was mounted | worn. In this configuration, the object to be heated 3 is taken in and out. The door 4 is mounted so as to be openable and closable with a hinge 8 as a fulcrum by urging a door arm 5 having a fulcrum on the door 4, a door guide roller 6 fixed and locked to the cooker 1 side, and a door spring 7. In addition, various electric components 9 such as a high-frequency oscillator, a heater, and a control board are arranged in the exterior of the cooking device 1 and the space of the heating chamber 2.

  Next, a related operation of the door 4 and the damper 10 which is a main part of the present invention will be described. When the door 4 is closed, as shown in FIG. 1, the inertial impact load P1 of the door 4 urged by the door spring 7 or the like pushes the convex portion 13 of the operating lever 12 that rotates at the fulcrum A11 on the cooker 1 side, and the arrow a It is the structure which is transmitted to the damper 10 by the movement of the direction and disappears by the buffering effect of the damper 10. There are various types of dampers 10 such as oil, air, grease, and a friction system depending on buffer conditions. The damper 10 this time needs to incorporate a return spring 14 for returning to the original state when the load on the damper 10 is released.

  When the door 4 is opened, as shown in FIG. 2, the inertial impact load P <b> 2 due to the dead weight of the door 4 containing a heavy object such as the observation window glass 15 is fixed to the door arm 5 interlocked with the movement of the door 4. The movement of the pin 16 pushes the connecting lever 18 to the opening side indicated by the arrow b. Then, the upper part of the connecting lever 18 rotates in the direction of the arrow c on the side opposite to the opening by the function of the fulcrum B17. Then, the projection of the operating lever 12 moves in the direction of the damper 10 indicated by the arrow d in conjunction with the movement of the connecting lever 18, and is transmitted to the damper 10 so that the inertial impact load P2 disappears.

The timing for activating the damper drag is not limited and may be activated at any time. However, if it is operated from the beginning, it feels awkward when opening and closing the door, and it takes time to open and close. Also, the damper drag just before the door is closed or just before the door may be operated, but if it is just before the door, it may not work well due to variations in the damper or assembly. Therefore, when the door is a practical timing for actuating the damper drag angle 1 to 30 ° from the closed terminal end, also good when the angle of 1 to 30 ° from the open time of termination.

Hereinafter, an example of the movement of the door 4 and an operation range of the damper 10 will be described with reference to FIG. When the door 4 is closed, the damper 4 is operated from an angle of 1 to 30 ° from the terminal end when the door 4 is closed, receives the inertial impact load P1 of the door 4 by the drag of the damper 10, and when the door 4 is also opened, When the door 4 is opened, the damper 10 is operated from an angle of 1 to 30 ° from the terminal end, and the inertial impact load P2 of the door 4 is received by the resistance of the damper 10 so that the impact force disappears.

Next, as shown in FIG. 5, the characteristic of the damper 10 is that the resistance of the damper 10 is strong at the first stage of the stroke, type A is weak at first, the type B is weak, and the resistance increases as the stroke increases. There are various types, such as type C, which maintains an average drag. The present invention employs Type B and Type C in the above damper configuration in order to relieve the momentary impact load when the damper 10 is joined via the door 4 and the operating lever 12 and smoothly open and close the door. . Normally, type A has a single-hole orifice structure for the damper cylinder, and type B and type C have a composite orifice structure and a swing type.

  As described above, according to the present invention, the impact on the cooker that occurs when the door is opened and closed disappears, and liquid food is not spilled or electrical components do not fail due to vibration.
