JP 2004-263903 A

  According to the open / close type operation panel described above, the moving speed of the operation panel is set by the torsion coil spring and the damper. By the way, the preference of the moving speed of the operation panel may be different depending on the user, and there is a case where it is desired to make the moving speed in accordance with the user's desire.

  In this case, in the conventional structure, the moving speed of the operation panel is changed by replacing the torsion coil spring or damper, and if there is no reserve of the torsion coil spring having a different elastic force or a damper having a different torque, a new part is ordered. It takes time and effort to change the moving speed of the operation panel.

  In view of the above, an object of the present invention is to provide an openable / closable structure for an openable / closable operation panel for a cooker that can easily adjust the moving speed of the operation panel.

  [1] In order to achieve the above object, the present invention provides an openable operation panel that is movable between a protruding position protruding from an opening provided in a cooker body and a storage position stored in the cooker body. In the open / close structure, the control panel includes a swing shaft that allows the operation panel to swing relative to the cooker body, a coil portion, and a pair of end portions that extend from both ends of the coil portion. Is fixed to an operation panel side fixing portion provided on the operation panel side, and the other end is fixed to a main body side fixing portion provided on the cooking device body side, and the operation panel is attached to the cooking device body. A torsion coil spring that is biased toward the protruding position, a position restricting mechanism that releasably fixes the operation panel at the retracted position, and a release by the position restricting mechanism to release the operation panel from the retracted position. When moving to the protruding position, the torsion coil A damper mechanism that decelerates the moving speed of the operation panel against the urging force of the operation panel on the operation panel, and a plurality of at least one fixing part of the operation panel side fixing part and the main body side fixing part is provided. The angle formed by both end portions of the torsion coil spring at the storage position can be switched by changing a fixing portion to which the end portion of the torsion coil spring is fixed among the plurality of fixing portions. To do.

  According to the present invention, since the angle formed by both ends of the torsion coil spring when the operation panel is in the storage position can be switched by changing the fixing portion that fixes the end, the operation panel is in the storage position. The biasing force of the torsion coil spring can be adjusted.

  Accordingly, the moving speed of the operation panel can be easily adjusted without replacing the torsion coil spring and the damper mechanism.

  [2] The opening / closing structure described above can also be used in a cooker having a plurality of operation panels. For example, there may be a stove opening / closing operation panel and a grill opening / closing operation panel provided on the front panel of the cooking device. When the openable operation panel for the cooking device is a three-mouth type cooking device, three operation buttons for the stove are arranged. For this reason, the openable control panel for the stove is relatively wide and heavier than the openable control panel for the grill.

  In the conventional cooker, since the same torsion coil spring and the same damper mechanism are used in both open / close type operation panels, if both operation panels are projected from the front panel at the same time, the open / close type operation panel for the light weight grill is used. The opening and closing speed is faster than the openable control panel for the stove. Thereby, when a user protrudes both operation panels simultaneously, a strange feeling may be felt.

  In order to prevent this, in the conventional product, a combination in which both operation panels have the same opening / closing speed is searched and adjusted from a plurality of types of torsion coil springs and damper mechanisms.

  However, in the conventional structure, there are a plurality of torsion coil springs with different elastic forces and a plurality of damper mechanisms with different torques at the time of assembly, so that the assembled parts may be mistaken, resulting in poor yield.

  According to the opening / closing structure of the operation panel of the present invention, the urging force can be adjusted by changing the angle formed by both ends of the torsion coil spring, and the opening / closing speeds of the plurality of operation panels can be matched. Therefore, it is not necessary to prepare a large number of torsion coil springs having different elastic forces and damper mechanisms having different torques as in the prior art, and the yield can be improved.

  [3] In the present invention, a storage box for storing the operation panel at the storage position is detachably provided in the cooker body, a main body side fixing portion is provided in the storage box, and the storage box has the plurality of fixings. In order to change the fixed portion to which the end portion of the torsion coil spring is fixed, it is preferable to provide a cutout portion that is cut out so that the outer surface and the inner surface of the storage box communicate with each other.

  According to this, it is possible to remove the storage box from the cooker body, insert a finger from the notch, and change the fixing portion to which the end of the torsion coil spring is fixed, so that the work of adjusting the biasing force of the torsion coil spring is easy It becomes.

Each stove burner 2 is composed of an external flame type burner provided with a pan bottom temperature sensor 2b that abuts on the bottom surface of the cooking container on the virtues 2a and detects its temperature.

  A grill door 3a and left and right front panels 5 and 5 are provided on the front portion of the stove body 1 exposed forward under the counter top.

  On the right front panel 5, three push buttons 6 a, 6 a, and 6 a that perform point-extinguishing operations of a total of three stove burners 2, that is, two front left and right and one rear side, are arranged in parallel. Below the arrangement of the three push buttons 6a, 6a, 6a, there is arranged an operation panel 7 that can protrude forward from an opening provided in the front panel 5.

  Similarly, the left front panel 5 is also provided with a push button 6b for performing a fire extinguishing operation of a grill burner (not shown) provided on the grill 3. In addition, an operation panel 7 that can project forward of the front panel 5 is disposed below the portion where the push button 6b is disposed.

  As shown in FIG. 2, each front panel 5 includes a panel main body 51 and the front surface of the portion of the panel main body 51 above the arrangement portion of the push buttons 6a, 6a, 6a for the combo burner 2 and the push buttons 6a, 6a, It is composed of a pair of upper and lower decorative plates 52 and 52 ′ formed of a metal such as aluminum attached to the front surface of the panel body 51 between the arrangement portion 6 a and the operation panel 7.

  The operation panel 7 can be stored in a storage box 8 that is detachably provided in the cooker body 1. The front surface of the storage box 8 is open, and a swing shaft 81 is provided at the lower front portion of the storage box 8. The operation panel 7 includes a swing frame 71 that is pivotally supported by the swing shaft 81 so as to be swingable in the front-rear direction. The operation panel 7 protrudes forward of the front panel 5 by swinging the swing frame 71 forward.

  On the upper surface 72 of the operation panel 7 arranged on the right front panel 5, as shown in FIG. 2, the setting of the heating mode, the heating temperature, etc., the setting of the heating time, etc. of each of the burners 2 are performed. Various operation switches 72a to be performed and a display unit 72b are provided. A decorative plate 73 is provided on the front surface of the swing frame 71. Although not shown, the operation panel 7 disposed on the left front panel 5 is provided with various operation switches for grills and a display unit.

  A pinion 82 is rotatably provided on the inner side surface of the storage box 8 via a rotary damper 82a. Further, an arc-shaped rack 71 a that curves in the swinging direction and meshes with the pinion 82 is provided on the side surface of the swinging frame 71. In the embodiment, the rotary damper 82a, the pinion 82, and the rack 71a constitute the damper mechanism of the present invention.

  A torsion coil spring 9 including a coil portion 91 and end portions 92 a and 92 b extending from both ends of the coil portion 91 is disposed in the storage box 8. One end portion 92 a of the torsion coil spring 9 is fitted and fixed to a groove-like operation panel side fixing portion 74 provided at the rear end portion of the swing frame 71. The other end portion 92b is inserted into and fixed to any one of three hole-shaped main body side fixing portions 83a, 83b, 83c provided on the inner bottom surface of the storage box 8. Thereby, the torsion coil spring 9 generates a biasing force that pushes the swing frame 71 forward. In addition, each main body side fixing | fixed part 83a-c is arrange | positioned at intervals in the up-down direction.

  A claw portion 75 that protrudes rearward is provided at the rear end portion of the swing frame 71. In the storage box 8, a conventionally known push-push type engagement mechanism 84 that is releasably engaged with the claw portion 75 when the operation panel 7 is in the storage position is provided. In the embodiment, the claw portion 75 and the engagement mechanism 84 constitute the position restriction mechanism of the present invention.

  Further, an overhanging portion 71 b that protrudes upward is provided at the rear end edge of the swing frame 71. Further, a protruding portion 8 a that protrudes downward is provided on the upper edge of the opening in front of the storage box 8. When the operation panel 7 is in the protruding position, the projecting portion 71b and the protruding portion 8a come into contact with each other. Thereby, the protruding position of the operation panel 7 is defined.

  Next, the operation of the operation panel 7 configured as described above will be described. When the operation panel 7 is in the storage position, when the decorative plate 73 located on the same plane as the front panel is pressed backward, the engagement between the push-push engagement mechanism 84 and the claw portion 75 is released. As a result, the operation panel 7 swings forward by the biasing force of the torsion coil spring 9.

  At this time, the pinion 82 meshing with the rack 71a receives a braking force due to the viscous resistance of the oil of the rotary damper 82a, and the moving speed of the operation panel 7 becomes slow. As a result, it is possible to prevent the operation panel 7 from protruding vigorously by the urging force of the torsion coil spring 9 and causing an impact at the protruding position.

  And the operation panel 7 stops in a protrusion position by the protrusion part 71b and the protrusion 8a contacting. When returning the operation panel 7 from the protruding position to the storage position, the decorative plate 73 may be pressed backward to engage the claw portion 75 and the push-push engagement mechanism 84.

  By the way, although the operation panel 7 of the embodiment is configured to gently move from the storage position to the protruding position by the damper 82a, if the moving speed from the storage position to the protruding position is too slow, the user feels uncomfortable. There is a fear. Conversely, if the moving speed is too fast, an impact will occur. Therefore, it is necessary to set the moving speed to be appropriate by the rotational resistance of the pinion 82 by the damper 82a and the urging force of the torsion coil spring 9.

  In the conventional product, the damper 82a is changed to one having a different oil viscosity or the torsion coil spring 9 is changed to one having a different elastic force so that the moving speed described above becomes appropriate. The movement speed was adjusted to be appropriate. However, in this case, it is necessary to prepare a plurality of types of dampers 82a and torsion coil springs 9, and it takes time to replace parts.

  Moreover, in the thing provided with the two opening-and-closing type operation panels 7 like the cooking appliance of embodiment, when both are pressed back simultaneously, it is desirable to move to a protrusion position from an accommodation position at the same speed. However, when the same type of damper 82a and torsion coil spring 9 are used, the right operation panel 7 operates three stoves, whereas the left operation panel 7 only operates the grill. There is a possibility that the weight of the board 7 is different and the board 7 does not move at the same speed. In addition to this, if the same type of damper 82a and torsion coil spring 9 are used due to individual differences of the operation panel 7, there is a possibility that they will not open at the same speed.

  In the cooking device of the embodiment, as the fixing portion 83 for fixing the end portion 92b of the torsion coil spring 9, first to third fixing portions 83a to 83c are provided at three positions with an interval in the vertical direction. Thus, the angle α formed by the two end portions 92a and 92b of the torsion coil spring 9 can be adjusted in three stages depending on which of the three fixing portions 83a to 83c is fixed to the end portion 92b.

  Therefore, the urging force of the torsion coil spring 9 can be changed without replacing the torsion coil spring 9, the moving speed of the operation panel 7 can be adjusted to an appropriate speed, and both the operation panels 7 and 7 can be adjusted. Can be adjusted so that the movement speeds of the two match.

  As shown in FIG. 4, a cutout 8b is formed in the upper right part of the storage box 8 of the embodiment. The storage box 8 is removed from the cooker body 1, and a finger is inserted through the cutout 8b. The end portion 92b of the torsion coil spring 9 is easily switched to one of the three fixing portions 83a to 83c.

  In addition, in embodiment, although demonstrated using the cooking appliance provided with two operation panels 7, it is not restricted to this, Even if the number of the operation panels 7 is 1 or 3 or more, the "damper" of this invention It is possible to obtain the effect that the moving speed of the operation panel 7 can be adjusted to an appropriate speed without replacing the torsion coil spring.

  In the embodiment, the case where the three main body side fixing portions 83a to 83c are provided has been described. However, the number of main body side fixing portions is not limited to three, and the effect of the present invention can be obtained with two or four or more. be able to. In the embodiment, the three main body side fixing portions 83a to 83c are arranged at intervals in the vertical direction. However, the main body side fixing portions 83a to 83c are not limited to this, and the two end portions 92a, It is only necessary that the angle α formed by 92b can be changed.

  In the embodiment, a plurality of main body side fixing portions 83 and a single operation panel side fixing portion 74 have been described. However, the present invention is not limited to this, and the main body side fixing for fixing the end portion 92b of the torsion coil spring 9 is described. Only one part 83 may be provided, and a plurality of operation panel side fixing parts 74 that fix the end 92a of the torsion coil spring 9 may be provided, or a plurality of both fixing parts 74 and 83 may be provided.
