JP 2006-317125 A JP 2006-317126 A

  In range hoods such as those described in Patent Documents 1 and 2, after most of the airflow including oil smoke and water vapor rising from below collides with the fixed hood and the current plate provided at the bottom of the movable hood, the fixed hood and movable hood It has a structure in which it is sucked from a suction port provided between the current plate and discharged to the outside.

  In such a structure, airflow may escape to the side of the main body, and it is required to improve the collection efficiency of oily smoke and water vapor.

  The oil smoke sucked into the intake flow passage is a phenomenon that is especially seen when the room temperature is low, but is likely to condense on the surface of the current plate.

  For this reason, the current plate is subjected to a surface treatment such as fluorine processing, and the current plate is easily removed to prevent dew condensation, and the surface of the current plate is easily wiped off during routine maintenance to improve the cleaning performance.

  However, the range hood is installed on the wall side (back side) of a high place, the current plate itself is large and cannot be moved, so it is difficult for the user to wipe the current plate when cleaning it. There was also a problem that it was difficult to remove.

  In addition, in the range hoods described in Patent Documents 1 and 2, a fixed hood / movable hood and a rectifying plate are used so that oil smoke or steam can be sucked in any position of the IH cooking heater or the gas stove. The opening width (the distance between the fixed hood / movable hood and the rectifying plate) of the suction port provided between the two is formed substantially uniformly.

  The rectifier plate on the movable hood side moves with the movement of the movable hood, but since this rectifier plate is fixed to the movable hood, the opening width of the suction port provided between the movable hood and the rectifier plate is It does not change.

  For this reason, when grilling fish or the like using a grill (heating means) provided in an IH cooking heater or gas stove, the grill exhaust port is normally provided on the wall side, so that oil smoke or steam discharged from the exhaust port is provided. The oil smoke and vapor that could not be sucked in from the suction port collide with the flow straightening plate and flow to the rear of the main body, so that condensation tends to occur on the flow straightening plate and the rear wall, and there is a lot of condensed water. Then, there was a drawback of dripping.

  In recent years, IH cooking heaters have become widespread. However, since the IH cooking heater generates heat by induction heating due to induction heating, the temperature around the IH cooking heater does not increase so much.

  For this reason, since the wall around the IH cooking heater cannot be heated, the temperature difference from the oily smoke and steam generated by cooking is increased, and condensation is more likely to occur on the wall surface. And in order to prevent dripping of this dew condensation water, the user had to wipe off dew condensation water and had the subject that the effort of cleaning took.

  Moreover, in the range hood provided with the drive device as disclosed in Patent Document 2, the drive motor, the pulley connected to the shaft of the drive motor, the wire wound around the pulley, and the position detection means are provided as one plate material. Since the drive device is unitized by placing it on the drive unit, when the drive motor is damaged or failed and replaced with a new drive motor, etc., the drive device unitized on the plate is removed and replaced, so the drive motor etc. However, there is a problem that the replacement work cost and the part cost are high.

  Furthermore, if the left and right movements are not aligned when the movable hood is stored and the drawer is moved, the sliding portions of the guide rail and the guide groove are bitten, resulting in defective storage and extraction.

  Furthermore, if there is an obstacle during the storing operation of the movable hood and the current plate, the obstacle may be caught.

  Moreover, there is a possibility that oil of oil smoke sucked into the range hood adheres to the sliding portions of the guide rail and the guide groove and the oil sticks.

  In view of the above-described problems, an object of the present invention is to provide a range hood that is unlikely to cause malfunctions in storage and extraction.

  Furthermore, in view of the above problems, an object of the present invention is to provide a range hood in which an obstacle is not caught or oil is not likely to stick.

  In order to achieve the above object, the range hood of the present invention is provided with a fan unit containing a fan for exhaust, a fixed hood provided at a lower portion of the fan unit, and a retractable hood that can be stored and pulled out of the fixed hood. A movable hood having a movable hood, wherein the movable hood is moved in a retractable and retractable manner, and the movable hood is provided on both right and left sides in the retracted and retracted direction. A movable hood drive control unit that controls driving, and the movable hood drive control unit has an alignment control function for controlling the movable hood drive device so as to align movements on both the left and right sides of the movable hood. Features.

  In the range hood of the present invention, the movable hood drive control unit has a movable hood temporary stop control function in which the movable hood storage movement operation is temporarily stopped before the movable hood is completely stored. Features.

  Furthermore, the range hood of the present invention is characterized in that the moving movement of the movable hood and the current plate is performed by a stop instruction to stop the operation of the range hood.

  In the movable hood drawer / storage movement operation and the rectifying plate (first rectifying plate 108a) grill operation position / cleaning position / storage movement operation, the switches at the respective positions are the first connecting member and the second connecting member. Turns on and off as the camera moves. The on / off signal is read by the main control circuit including the micro, and the operation of the movable hood and the movable hood driving device and the rectifying plate driving device for moving the rectifying plate (first rectifying plate 108a) are performed. It is controlled properly.

  The positioning control of the movable hood will be described with reference to FIG.

  In the operation of pulling out the movable hood 107, the second connecting member 134 on the left side is moved from the rear position 138a (hood) storage 138a (storage state of the movable hood 107) to the front end position 138b and (hood) projection 138b (drawing state of the movable hood 107). ) The movable hood 107 moves.

  Along with the above-described operation of the second connecting member 134, the second connecting member 203 on the right side is moved from the rear position 205 a · (hood) storage 205 a (storage state of the movable hood 107) to the front end position 205 b · (hood) protrusion 205 b (movable). The hood 107 is pulled out).

  In the operation of pulling out the movable hood 107, the moving operation difference (displacement) between the left and right second connecting members 134.203 is corrected by temporarily stopping at the intermediate second positions 137c and 204c. By correcting the movement operation difference (displacement), the operation failure due to the biting at the sliding portion of the guide rail or the guide groove does not occur, and the movable hood 107 is reliably pulled out.

  In the illustration of FIG. 16, the second connecting member 134 on the left side arrives at the intermediate second position 137c, and the second connecting member 203 on the right side moves to the intermediate second position 137c when the second drive motor 120 is on standby. Arrives late. By moving the second drive motor 120 and the fourth drive motor 201 at the same time after pausing the delayed fourth drive motor 201 for a predetermined time (for example, 500 ms), the left and right side moving operations of the movable hood are aligned. Matching is done.

  In this way, a pair of hood drive motors (movable hood drive devices) that apply a moving operation force (push / pull force) to the left and right sides of the movable hood are controlled by the left and right alignment control function of the movable hood drive control unit. .

  For this reason, when moving and retracting the movable hood, the left and right sides of the movable hood do not go too quickly or too late, and they are aligned and moved together, causing malfunction due to biting. The movable hood 107 is reliably pulled out.

  The 500 ms pause will be described.

  The 500 ms pause is to align the start positions at which the pair of drive motors (second drive motor 120 and fourth drive motor 201) resume operation.

  When the operation of the fourth drive motor 201 that has stopped after arriving late at the intermediate second position 204c is resumed, the moving operation on the fourth drive motor 201 side is delayed until momentum is gained. In order to eliminate irregularities caused by this delay, a 500 ms pause was provided.

  The obstacle pinching prevention operation / retry operation will be described with reference to FIG.

  These operations are achieved by the movable hood temporary stop control function, the movable hood slow speed transition control function, and the movable hood movement operation reversal control function provided in the movable hood drive control unit.

  The movable hood is temporarily moved at the third intermediate position 205c (hood) temporary stop 205c (before the movable hood is stored) in a moving operation in which the storage is performed.

  After the temporary stop has elapsed for a predetermined time (for example, 700 ms), the second drive motor 120 and the fourth drive motor 201 are restarted to complete the storage of the movable hood. The storage of the movable hood is completed when the second connecting member 134 reaches the left rear position 138a · (hood) storage 138a, and the second connecting member 203 reaches the right rear position 205a · (hood) storage 205a. To do.

  As described above, the movable hood is temporarily stopped by the pause control function that pauses before the storage is completed, so that the obstacle can be easily evacuated as compared to the case where the storage is completed without the temporary stop. Obstacle pinching due to is prevented.

  The movable hood operates the second drive motor 120 and the fourth drive motor 201 at 50% of the rated torque from the temporary stop position until the storage is completed. The movable hood is stored slowly with a weak force of slow speed.

  For this reason, the movable hood does not strongly tighten the obstacles between them, so that the obstacles are not damaged. Thus, safety is improved by the slow speed transition control function of the movable hood.

  If an obstacle is caught by mistake, the storage of the movable hood is not completed. Therefore, even if time elapses, the second connecting member 134 is positioned at the left rear position 138a · (hood) storage 138a, and the second connecting member 203 is also positioned at the right rear position 205a · (hood) storage 205a. Not reach.

  In this case, when a certain time has elapsed, the movable hood is reversely moved in the pulling-out direction and temporarily stopped at the third intermediate position 2. Then, the movable hood is again moved in the storage direction. At this time, since the second drive motor 120 and the fourth drive motor 201 are operated at 100% of the rated torque, the movable hood is quickly stored.

  If the movable hood is not completely stored even in this re-storage, the movable hood is reversed in the pulling-out direction and an error is notified.

  Thus, since the movable hood moves in the pull-out direction by the moving motion reversal control function of the movable hood, the obstacle can be easily removed by being caught, and the safety is improved.

Although the above-described obstacle pinching prevention operation / retry operation has been described with respect to the movable hood, the same operation is performed on the current plate (first current plate 108a).

The rectifying plate (first rectifying plate 108a) moves back and forth between the second intermediate position (137c, 204c) and the rear position (137a, 202a). Except where the moving operation range is different from the movable hood, the obstacle pinching prevention operation / retry operation is common to the movable hood.

  When the rectifying plate (first rectifying plate 108a) and the movable hood are moved, the second connecting member and the first connecting member are moved back and forth along the guide rail and the guide groove. Oil smoke or the like generated from the range adheres to the guide rail or the guide groove and the oil can be fixed.

  This oil adhesion is removed by the movement operation of the current plate (first current plate 108a) and the movable hood. This removal will be described later.

  The positioning of the movable hood will be described with reference to FIGS.

  First, the hood alignment timing chart shown in FIG. 18 will be described.

  When the operation switch 113c is turned on, the second drive motor 120 and the fourth drive motor 201 rotate forward and the movable hood is pulled out. When the second connecting member 134 that moves forward arrives at the intermediate position 137c, the switch at the intermediate position 137c is turned on, and the second drive motor 120 stops.

  The fourth drive motor 201 continues to operate. When the second connecting member 203 arrives at the intermediate position 204c with a delay, the switch at the intermediate position 204c is turned on and the fourth drive motor 201 stops.

After the switch at the intermediate position 204c is turned on, after the elapse of 500 ms, the second drive motor 120 and the fourth drive motor 201 are simultaneously rotated in the forward direction to further pull out the movable hood.

  When the second connecting member 134 arrives at the front end position 138b, the switch at the intermediate position 138b is turned on and the second drive motor 120 is stopped. When the second connecting member 203 arrives at the front end position 205b with a delay, the switch at the front end position 205b is turned on and the fourth drive motor 201 is stopped.

  As described above, at the intermediate position 137c and the intermediate position 204c, the second drive motor 120 that arrives first waits for the fourth drive motor 201 that arrives late, aligns the movable hood, and rotates the movable hood together. Thus, the malfunction due to the biting is eliminated, and the movable hood 107 is reliably pulled out.

  Further, the positioning of the movable hood will be described from the aspect of the operation flowchart with reference to FIG.

  In step 2001, the operation switch 113c is pressed. The second drive motor 120 and the fourth drive motor 201 start operation, and the movable hood is pulled out to the user side (step 2002).

  In step 2003, arrival of the second connecting member 134 at the intermediate position 137c is sequentially determined. When arrival is confirmed, the second drive motor 120 stops operation (step 2004).

  In step 2005, arrival of the second connecting member 203 at the intermediate position 204c is sequentially determined. When arrival is confirmed, the fourth drive motor 201 stops operation (step 2006).

The above steps (2003 and 2005) are executed until the arrival of the second connecting member 134 and the arrival of the second connecting member 203 are observed.

  After 500 ms has elapsed since the operation of the delayed fourth drive motor 201 is stopped (step 2007), the second drive motor 120 and the fourth drive motor 201 start operation simultaneously (step 2008), and the movable hood is pulled out to the user side. Carry like.

  In step 2009, arrival of the second connecting member 134 at the front end position 138bc is sequentially determined. When arrival is confirmed, the second drive motor 120 stops operation (step 2010).

  In step 2011, arrival of the second connecting member 203 at the front end position 205bc is sequentially determined. When arrival is confirmed, the fourth drive motor 201 stops operation (step 2012).

  Thus, the operation for pulling out the movable hood is completed (step 2013).

  Next, a retry operation timing chart for preventing oil sticking and preventing obstacles (when an abnormality occurs when the current plate is housed) will be described with reference to FIG.

  This operation is a mode when the operation of the range hood is stopped.

  When the operation switch 113a is turned on, the first drive motor 116 and the third drive motor 200 rotate forward and the rectifying plate (first rectifying plate 108a) is pulled out. When the first connecting member 134 that moves forward arrives at the intermediate position 137c, the switch at the intermediate position 137c is turned on, and the first drive motor 116 stops.

  The third drive motor 200 continues to operate, and when the first connecting member 202 arrives at the intermediate position 204c, the switch at the intermediate position 204c is turned on and the third drive motor 200 stops.

  The first drive motor 116 and the third drive motor 200 are simultaneously reversely rotated 500 ms after the third drive motor 200 is stopped.

  As a result of this reverse rotation, the current plate (first current plate 108a) moves in the storage direction, contrary to the previous movement. When the first connecting member 202 arrives at the third intermediate position 205c, the switch at the third intermediate position 205c is turned on, and the first drive motor 116 and the third drive motor 200 are stopped.

  When the operation of the range hood is stopped, the rectifying plate (first rectifying plate 108a) reciprocates, so that the first connecting member 134 and the first connecting member 202 remove oil adhering to the guide rail and the guide groove.

  By this removal, prevention of oil sticking is suppressed. For this reason, in the next use of the range hood, there is no occurrence of a defective moving operation of the movable hood and the current plate (first current plate 108a).

  Now, after stopping at the third intermediate position 205c, the first drive motor 116 and the third drive motor 200 are reversely rotated after 700 ms has elapsed. With this reverse rotation, the housing of the current plate (first current plate 108a) is completed.

  In the operation for completing the storing of the current plate (first current plate 108a), the first drive motor 116 and the third drive motor 200 are rotated at a rated torque of 50%. Since the rectifying plate (first rectifying plate 108a) is stored at a slow speed with a weak force, it is possible to prevent the obstacle from being caught.

  Moreover, even if it is pinched, the force stored in the rectifying plate (first rectifying plate 108a) is weak, so that the obstacle can be prevented from being damaged.

  The storage completion operation is executed for a maximum of 6 seconds. When the switches at the rear positions 137a and 207a are not turned on within 6s due to an obstacle being caught or other causes, the reverse rotation of the first drive motor 116 and the third drive motor 200 is stopped.

  After a pause of 500 ms, the first drive motor 116 and the third drive motor 200 are rotated forward this time. Since the rectifying plate (first rectifying plate 108a) is pulled out, the obstacle that has been caught can be easily removed.

  When the third intermediate position 205c is switched on, the forward rotation of the first drive motor 116 and the third drive motor 200 stops. After waiting for 3 seconds, the first drive motor 116 and the third drive motor 200 are reversed.

  At this time, the first drive motor 116 and the third drive motor 200 are reversely rotated at the full rated torque. This is because the trapped obstacle has already been removed and does not exist.

  The reverse rotation of the first drive motor 116 and the third drive motor 200 at this full rated torque is executed for 3 seconds. When the switches at the rear positions 137a and 207a are not turned on, the reverse rotation of the first drive motor 116 and the third drive motor 200 is stopped.

  Then, the first drive motor 116 and the third drive motor 200 are rotated forward by taking a pause of 500 ms, and the operation is terminated when the third intermediate position 205c is switched on to notify the abnormality.

  Between the third intermediate position 205c and the rear position (137a, 207a) described above, the first drive motor 116 and the third drive motor 200 prevent obstacle pinching and retry operation by repeating forward / reverse rotation. It is possible to cope with obstacles related to storage movement of the board.

  Further, oil sticking prevention / obstruction pinching prevention / retry operation will be described from the aspect of the operation flowchart with reference to FIGS.
