<Operation of garbage disposal device>
Next, the operation of the garbage processing apparatus 1 shown in FIG. 1 will be described with reference to the drawings. A user of the garbage processing apparatus 1 throws garbage into the loading opening 7 and closes the loading opening 7 with the lid 11. FIG. 5 is an explanatory view showing the operation of the lid switch 12. First, as shown to Fig.5 (a), the direction of the cover 11 is attached to the insertion opening part 7 according to the attachment / detachment position 7a. In this state, the position detection magnet 15 of the lid 11 does not face either the first proximity sensor 16a or the second proximity sensor 16b of the closing opening 7.

  Next, when the lid 11 is rotated in the direction of arrow a and the orientation of the lid 11 is adjusted to the first operating time setting position 7b as shown in FIG. 5B, the position detection magnet 15 of the lid 11 is , Facing the first proximity sensor 16a of the closing opening 7. As a result, the output of the first proximity sensor 16a changes from off to on, and the control unit 17 can determine that the direction of the lid 11 is adjusted to the first operating time setting position 7b.

  Then, when the output of the first proximity sensor 16a is on for a predetermined time, the control unit 17 shown in FIG. 1 adjusts the direction of the lid body 11 to the first operation time setting position 7b. It is determined that the first operation time has been selected, and the driving of the motor 6 is started.

  Specifically, the rotation operation that repeats the forward rotation and the reverse rotation operation every several seconds, for example, every 5 seconds, is performed for a time (for example, 30 seconds) set in advance as the first operation time. The rotation speed of the motor 6 is set to about 100 rpm.

  Now, after the output of the first proximity sensor 16a is turned on, the control unit 17 determines that the lid body 11 is further rotated when the output is turned off within a predetermined time. Monitoring of the outputs of the first proximity sensor 16a and the second proximity sensor 16b is continued, and the motor 6 is not driven.

  When the lid 11 is further rotated in the direction of arrow a and the orientation of the lid 11 is adjusted to the second operating time setting position 7c as shown in FIG. 5C, the position detection magnet 15 of the lid 11 is , Facing the second proximity sensor 16b of the input opening 7. As a result, the output of the second proximity sensor 16b changes from off to on, and the control unit 17 can determine that the direction of the lid 11 is adjusted to the second operation time setting position 7c.

  Then, when the output of the second proximity sensor 16b is on for a predetermined time, the control unit 17 adjusts the direction of the lid 11 to the second operation time setting position 7c, and the user performs the second operation. It is determined that the time has been selected, and the rotation operation of the motor 6 as described above is performed for a time (for example, 1 minute) preset as the second operation time.

  As described above, when the desired operation time can be selected from a plurality of operation times while rotating the lid 11 in one direction, the first position close to the attachment / detachment position 7a that is the operation stop position. By setting the operation time at the operation time selection position 7b to be short, the user can perform intuitive operations.

  Next, the crushing process executed by rotating the motor 6 with the lid switch 12 as described above will be described with reference to FIGS. Here, a water supply port 14 is formed in the lid 11, and water can be supplied into the hopper 3 even when the charging opening 7 is closed with the lid 11. Water is supplied into the hopper 3 by flowing water into the hopper 3.

  When the motor 6 rotates, the crushing unit 4 has the first rotating crushing blade 22 and the third rotating crushing blade 24 that rotate together. On the other hand, the second fixed crushing blade 23 and the fourth fixed crushing blade 25 do not rotate.

  As a result, the garbage thrown into the hopper 3 from the charging opening 7 is stirred by the stirring arm 29 of the first rotary crushing blade 22 and roughly in cooperation with the arm 32 of the lower second fixed crushing blade 23. The crushed raw garbage is fed between the arms 32 of the second fixed crushing blade 23.

  The raw garbage sent between the arms 32 of the second fixed crushing blade 23 is rotated by the lower third rotating crushing blade 24, so that the comb teeth 32a of the arm 32 of the second fixed crushing blade 23 and The third rotary crushing blade 24 is finely crushed by meshing with the comb teeth portion 35a of the arm 35.

  The garbage that is crushed by the cooperation of the second fixed crushing blade 23 and the third rotary crushing blade 24 is further improved by the cooperation of the arms 35 of the third rotary crushing blade 24 and the slit 39 of the fourth fixed crushing blade 25. It is finely crushed and discharged downward from the slit 39.

  The control unit 17 stops the rotation of the motor 6 after the operation time set by the lid switch 12 has elapsed. Further, the controller 17 can open the lid 11 when the lid 11 is rotated during the rotation of the motor 6 and the output of the first proximity sensor 16a or the second proximity sensor 16b is turned off. Therefore, the rotational drive of the motor 6 is stopped. Thereby, the motor 6 is rotationally driven in a state where the lid 11 is opened, so that the rotary crushing blades are not rotated.

  FIG. 6 is a plan view showing a modification of the lid switch. The lid switch 12A shown in FIG. 6 includes a first proximity sensor 16a and a second proximity sensor so that the first operation time setting position 7b and the second operation time setting position 7c are arranged across the attachment / detachment position 7a. 16b.

  Accordingly, as shown in FIG. 6A, the direction of the lid 11 is attached to the input opening 7 in accordance with the attaching / detaching position 7a, and the lid 11 is rotated in the direction of arrow a, so that FIG. As shown in FIG. 5, the first operation time can be selected by matching the direction of the lid 11 with the first operation time setting position 7b. Further, by rotating the lid 11 attached to the input opening 7 in the direction of the opposite arrow b in accordance with the attaching / detaching position 7a, the orientation of the lid 11 is changed to the second operation as shown in FIG. 6C. The second operation time can be selected in accordance with the time setting position 7c.

  Thus, since the first operation time setting position 7b and the second operation time setting position 7c can be selected directly from the attachment / detachment position 7a, the operation is easy when there are two types of operation time that can be selected. .

  As a further modification of the lid switch, although not shown, a configuration in which a rotating body is provided in a part of the lid body 11 and can be locked by rotation of the rotating body, instead of a configuration in which the entire lid body 11 is rotated. It is also good. In this case, each magnet is provided on the rotating body side.

  Further, although two types of operation time can be selected, it is possible to adopt a configuration in which two or more types of operation time can be selected by increasing the number of proximity sensors.

  Furthermore, as a modification of the whole garbage disposal apparatus 1, it is good also as a structure which enabled automatic water supply in the hopper 3 using a solenoid valve etc. FIG. In this case, if it is set as the structure which can switch water supply time according to the operation time set with the lid switch 12, use of useless water is suppressed and it leads to water saving.

  The crushing method in the garbage disposal apparatus 1 may be a so-called hammer mill type in which a fixed hammer or a swingable hammer is provided on a rotationally driven disk disposed at the bottom of a cylindrical hopper. .

  The present invention is installed in a kitchen or the like of a building and can improve the convenience of processing garbage.
