Description

  The present invention relates to a garbage disposal device for crushing garbage generated in a kitchen or the like, and in particular, when automatically supplying crushed water supplied to a hopper during crushing of garbage, the lock timing of an opening / closing lid to the hopper By automatically supplying water with a slight delay, cuffs and the like are prevented from being wetted by automatically supplied tap water.

  A grinder-type apparatus is known as a garbage disposal apparatus for crushing garbage such as garbage generated in ordinary households and restaurants. The grinder-type garbage disposal apparatus has a crushing unit in which rotating crushing blades and combing crushing blades each having a comb-like tooth portion provided radially are stacked alternately (see, for example, Patent Documents 1 and 2). The crushing unit is housed in a hopper and crushes garbage etc. while rotating the rotary crushing blade and discharges it to the sewer pipe or the discharge treatment tank side.

  In such a garbage disposal apparatus, the crushing process is performed in a state where the opening of the hopper (corresponding to the opening of the sink) is closed by the opening / closing lid. Therefore, the on / off control of the crushing process is often performed in synchronization with opening / closing of the opening / closing lid. Here, the opening and closing of the opening / closing lid means locking and unlocking of the opening / closing lid mounted on the hopper to the hopper.

  By the way, when crushing garbage, tap water is used as crushing water (crushing water), so water is supplied to the hopper in connection with crushing operation. There is a case where water is automatically supplied to the hopper. This is because in the case of automatic water supply, a water supply amount recommended in advance can be secured, so that an optimal water amount for the crushing process can always be supplied into the hopper.

  The automatic water supply may be performed from a tap water faucet (water tap) provided on the upper surface side of the sink or may be supplied directly to the hopper through the above-described opening / closing lid. When performing an automatic water supply process, a water supply process and a crushing process are performed simultaneously in connection with the lock | rock of the opening-and-closing lid with respect to a hopper.

  However, when automatic water supply is performed in synchronization with the lock of the opening / closing lid in this way, the water supply process is started almost simultaneously with the locking of the opening / closing lid. Before leaving the open / close lid, tap water is suddenly discharged from the faucet, and in some cases, the user's cuffs and the like may be wetted by the tap water.

  In addition, when controlling on / off of the crushing process in relation to opening / closing of the opening / closing lid, it should be confirmed by a buzzer or the like whether or not the opening / closing lid is securely locked and transitioned to the crushing processing mode. preferable.

  Therefore, the present invention solves such a conventional problem, and proposes a garbage disposal device in which the automatic water supply timing is delayed with respect to the lock timing of the opening / closing lid.

In order to achieve the above-described problem, the invention described in claim 1 includes a hopper attached and fixed to a sink,
A crushing unit for crushing the garbage contained in the hopper;
An opening / closing lid for closing the opening of the hopper;
A detecting means provided between the open / close lid and the hopper and detecting an open / closed state of the open / close lid;
An automatic water supply means composed of a tap water faucet provided on the upper surface side of the sink, and an adjusting means for adjusting the water discharge amount of the tap water provided in association with the faucet and supplying water to the hopper ,
It consists of a drive motor that drives the crushing unit and a control unit that controls the automatic water supply means,
When the closed state of the open / close lid is detected by the detection unit, the control unit controls the adjustment unit of the automatic water supply unit after a predetermined time from the detection timing to start the automatic water supply process from the faucet. Then, the crushing process is started by driving the drive motor from a point of time later than the automatic water supply process .

  In this invention, the opening / closing lid is mounted on the hopper, and the opening / closing lid is rotated in a predetermined direction to lock the opening / closing lid to the hopper. The on / off valve provided in the automatic water supply means opens at a timing delayed by a predetermined time ta (for example, 1 to 2 seconds) from the timing at which this detection state is detected by the detection means and the detection signal is obtained. Water discharge starts. If one to two seconds have passed since the lock of the open / close lid, the user's hand is away from the open / close lid, so even if tap water is discharged from the faucet, the cuff gets wet by the discharged tap water. There is nothing.

  When crushing garbage, in order to increase crushing efficiency and eliminate clogging of crushed materials in the discharge pipe, the stage before the crushing process is started, that is, before the motor that drives the crushing unit rotates. It is preferable to supply tap water into the hopper at the stage. For this reason, control is performed so that automatic water supply starts after a predetermined time ta has elapsed after lock detection of the open / close lid, and crushing processing starts after a predetermined time (predetermined time tb after lock detection) has elapsed after the start of automatic water supply. Is done.

  The notification means can be driven at the timing when the detection signal is obtained. With this notification sound, it is possible to easily confirm that the open / close lid is securely locked and transition to the crushing processing mode. In particular, when the crushing process starts after the locking timing of the opening / closing lid, the rotation sound of the drive motor and the rotary crushing blade cannot be confirmed, so if there is no notification processing by this notification sound, the opening / closing lid is locked, and This is because it cannot be confirmed whether or not the crushing processing mode is executed.

  When the notification means is driven both at the start and end of the crushing processing mode, it is impossible to determine which notification sound represents the start of the crushing processing mode, so the sounding method (sound transmission pattern) is changed. .

  In addition, a notification sound may be sounded during the crushing process mode, for example, when the crushing process reaches the middle of the set time. This is because the progress of the crushing process can be grasped. As means for recognizing the start and end of the crushing processing mode, voice guidance, message display, and the like can be considered in addition to the notification means.

  As a crushing unit built in the hopper, rotary crushing blades and fixed crushing blades are alternately stacked, and the rotary crushing blades are driven to rotate and crush the garbage with the rotary crushing blades and fixed crushing blades. A discharging grinder type crushing unit can be used. It can also be applied to hammer mill type and chain mill type crushing units.

  In this invention, automatic water supply is performed with a delay from the locking timing of the opening / closing lid.

  According to this, since tap water is discharged after an operator's hand leaves | separates from an opening-and-closing lid | cover, it can prevent reliably getting an operator's cuff wet.

  Embodiments of the garbage disposal apparatus of the present invention will be described below with reference to the drawings.

  FIG. 1 is a front sectional view showing an outline of the configuration of the garbage disposal apparatus 1 according to this embodiment. The garbage disposal apparatus 1 is the grinder type described above, and is installed on the back side of the kitchen sink S provided in the kitchen facility. It attaches so that the opening part So of the kitchen sink S may be plugged up. The garbage (crushed material) crushed by the garbage treatment apparatus 1 is discharged to the sewage pipe or the discharge treatment tank (both not shown).

  A faucet 100A is attached and fixed to the upper surface side of the kitchen sink S. The faucet 100A includes a faucet body 101, a water discharge port 102 led out from the faucet body 101 to the kitchen sink S side, and an operation plug (handle) 103 for adjusting the amount of water.

  The main water pipe 110 is branched into two via a water stop cock 113, and a water outlet 102 a is connected to one branch pipe 111. In relation to the water outlet 102 a, the first branch pipe 111 in the faucet body 101 is provided with an adjustment valve 106 that adjusts the amount of water discharged by raising and lowering the operation plug 103.

  The other branch pipe 112 branched from the water main pipe 110 is connected to the other water outlet 102b via the water stop cock 114 and the on-off valve 100B. The on-off valve 100B functions as a water discharge amount adjusting valve for adjusting the water discharge amount of tap water, and an electromagnetic valve is used in this example. The on-off valve 100B is provided separately from the faucet body 101.

  In the present invention, the faucet 100A and the on-off valve 100B constitute an automatic water supply means 100. The automatic water supply means 100 can also be controlled by a control means 120 that controls the whole garbage disposal apparatus 1. The control means 120 is supplied with a detection signal Sa from the detection means 6 (magnetic sensor 6b) related to the open / close lid 11, and an automatic water supply process is performed at a predetermined timing based on the detection signal Sa.

  In the above description, the normal tap water adjustment and the automatic water supply means are completely separated from each other. However, for example, the on-off valve 100B constituting the automatic water supply means 100 and the adjustment valve 106 may be shared. In this case, for example, the on-off valve 100B may be configured as an interlocking on-off valve so that the amount of water discharged can be adjusted by the operation plug 103, and the adjusting valve 106, the branch pipe 111, and the water outlet 102a are not required. .

Then, the garbage processing apparatus (apparatus main-body part) 1 is demonstrated.
As shown in FIG. 2, the garbage processing apparatus 1 has a cylindrical shape and has a hopper 3 into which garbage or the like is charged. The upper end of the hopper 3 is fitted and fixed to the opening So of the kitchen sink S via the attachment means 2 (shown by a chain line).

  The crushing unit 4 is mounted inside the hopper 3 so as to be detachable from the hopper 3. The crushing unit 4 has the third rotary crushing blade 16 at the lowermost stage, and a fitting portion 37 provided on the lower surface of the hub is fitted to the drive shaft 10 of the reduction unit (not shown). The lower part of the hopper 3 which is the apparatus main body is a housing (case) for fixing to the kitchen sink S, and a drive motor and a speed reduction unit as drive means are installed in the housing (not shown). The drive motor rotates the rotary crushing blade of the crushing unit 4 via the speed reduction unit. Although details are not shown, the drive shaft 10 for transmitting the driving force to the crushing unit 4 and the fitting portion 37 of the crushing unit 4 are formed in a square shaft shape or a spline shaft shape so as to engage with each other. .

  The hopper 3 is an upright cylindrical tubular body having a pair of fitting portions (in this example) extending downward from the input opening 7 side at a position 180 ° apart on the inner peripheral surface in this example. Then, a groove portion 3a is formed. The crushing unit 4 is inserted into and removed from the input opening 7 and is detachable from the hopper 3.

  A drain pipe connection port 8 is provided at the lower end of the peripheral surface of the hopper 3. A bottom plate 9 inclined toward the drain pipe connection port 8 is provided inside the hopper 3, and the central portion of the bottom plate 9 serves as a bearing portion that receives the drive shaft 10 of the reduction unit.

  An opening / closing lid (shown by a chain line) 11 shown in FIG. 1 is detachably attached to the charging opening 7 of the hopper 3. When the garbage disposal apparatus 1 is used, the input opening 7 is closed by the open / close lid 11 so that a hand or the like is not inadvertently inserted into the hopper 3 during the garbage treatment, and the crushed garbage Garbage is prevented from scattering to the kitchen sink S side.

  A drive motor for the crushing unit 4 is started in conjunction with the opening / closing lid 11. Therefore, the detection means 6 which detects that the closing opening part 7 was obstruct | occluded using the permanent magnet 6a etc. which were provided in the opening / closing lid | cover 11 is provided. When it is detected by the magnetic sensor 6b provided on the hopper 3 side that the closing opening 7 is closed (locked), the control means 120 controls the drive of the drive motor and the like.

The crushing unit 4 will be described with reference to FIG.
3 shows the first rotary crushing blade 12 arranged at the uppermost stage of the crushing unit 4, FIG. 3A is a plan view thereof, FIG. 3B is a front view thereof, and FIG. 3C is a side view thereof. The first rotary crushing blade 12 includes a single stirring arm 20 that extends horizontally from the side portion of the bearing portion 19. As for the 1st rotation crushing blade 12, the pressing surface 20a is formed in the front and back both surfaces in the rotation direction of the stirring arm 20. As shown in FIG.

  The pushing surface 20 a is an inclined surface (tapered surface) inclined in a direction in which the upper end protrudes from the lower end on both side surfaces of the stirring arm 20. By forming the pushing surfaces 20a on both side surfaces of the agitating arm 20, the first rotary crushing blade 12 can apply a pressing force to the garbage that is in contact with the pushing surface 20a by bidirectional rotation. it can. Thereby, the 1st rotation crushing blade 12 takes in garbage by rotation operation, and pushes it into the crushing blade of a lower stage.

  Moreover, the edge 20b is formed in the lower end side of the both sides | surfaces of the pushing surface 20a, and the 1st rotation crushing blade 12 is a crushing blade which crushes garbage roughly in cooperation with the 1st fixed crushing blade 13 shown in FIG. Function.

  A handle 21 is formed on the upper surface of the stirring arm 20 in the first rotary crushing blade 12. The handle 21 is provided at a position 90 ° away from the stirring arm 20 so as to extend from the bearing portion 19 to the left and right by the same length. The handle 21 functions as a grip portion (handle) when pulling up the crushing unit 4.

  Since the handle 21 is used as a gripping portion, the handle 21 is selected to have a length enough for a finger. The bearing portion 19 is provided with an insertion hole 19a through which a shaft head (locking portion) 36a of a rotary drive shaft 36 (see FIG. 7) provided on the third rotary crushing blade 16 described later can be inserted. The insertion hole 19a has a D-shaped cross section. Accordingly, the corresponding portion of the rotary drive shaft 36 has a D-shaped cross section, so that both are rotationally integrated.

  4 shows the first fixed crushing blade 13 disposed in the lower stage of the first rotary crushing blade 12, FIG. 4A is a plan view, FIG. 4B is a front view, and FIG. 4C is a side view thereof. The first fixed crushing blade 13 includes two arms 23 extending horizontally from the hub 22 at intervals of 180 degrees. Each arm 23 has a flat plate shape, and edges are formed on the upper and lower ends of both side surfaces, and functions as a crushing blade in cooperation with the first rotary crushing blade 12 and the second rotary crushing blade 14 shown in FIG.

  Each arm 23 is provided with a tab 24 that functions as a rotation preventing means at each tip. The tab 24 is an arm extending in the vertical direction so as to extend in the longitudinal direction of the hopper 3, and the rotation of the first fixed crushing blade 13 can be performed by fitting the tab 24 into the fitting groove 3 a of the hopper 3. regulate. In this example, a long tab having an entire length selected in consideration of the mounting position (depth) of the first rotary crushing blade 12 with respect to the hopper 3 is used.

  The reason why the long tabs 24 are used is to ensure that the rotation of the first fixed crushing blade 13 is restricted. The second is to fill the fitting groove 3a with the tab 24 while reducing the space of the fitting groove 3a as much as possible. For this reason, the tab 24a extending upward is selected several times longer than the tab 24b provided below the arm 23, and the fitting length with respect to the fitting groove 3a is made longer. Further, when the crushing unit 4 is mounted on the hopper 3 as shown in FIG. 1 by lengthening the upper tab 24a in this way, the space from the input opening 7 side to the tip of the upper tab 24a is reduced, and the fitting is performed. The crushed garbage is prevented from adhering in the groove 3a.

  As shown in FIG. 4C, the width of the upper end side of the tab 24 is selected so as to be substantially the same as the width of the fitting groove 3a, and becomes slightly narrower toward the lower end. This is to reduce backlash after the tab 24 is mounted on the fitting groove 3a and to more smoothly engage the tab 24 with the fitting groove 3a.

  The lower tab 24b is formed so that a gap of a predetermined height is formed when the second rotary crushing blade 14 is interposed between the first fixed crushing blade 13 and the second fixed crushing blade 15. Is provided. Therefore, in this example, the length of the lower tab 24b is selected to be approximately ½ of the length to the cutting edge of the second rotary crushing blade 14.

  The diameter of the inner hole 23a of the hub 22 is larger than the diameter of the second rotary crushing blade 14 shown in FIG. 5 and the diameter of the rotary drive shaft 36. Each dimension does not interfere.

  FIG. 5 shows the second rotary crushing blade 14. The second rotary crushing blade 14 is disposed in the lower stage of the first fixed crushing blade 13. FIG. 5A is a plan view thereof, and FIG. 5B is a cross-sectional view thereof taken along the line AA.

  The second rotary crushing blade 14 includes three arms 28 that extend radially from the hub 27 at intervals of 120 degrees. Each arm 28 has a radius slightly shorter than the inner diameter of the hopper 3 so as not to contact the inner wall of the hopper 3. Each arm 28 is formed with a comb tooth portion 28a having a predetermined pitch on the bottom surface.

  An engagement hole 27 a is formed at the center of the hub 27 of the second rotary crushing blade 14, and is fitted to the rotation drive shaft 36, whereby a rotational force is applied to the second rotary crushing blade 14. Therefore, like the second rotary crushing blade 14, the engagement hole 27 a that comes into contact with the second rotary crushing blade 14 is non-circular (for example, a square hole) so as to be rotationally integrated with the rotary drive shaft 36. The cross section may have a D shape as described above.

  FIG. 6 shows an example of the second fixed crushing blade 15. The 2nd fixed crushing blade 15 is arrange | positioned at the lower stage of the 2nd rotary crushing blade 14 so that the 2nd rotary crushing blade 14 may mesh | engage. 6A is a plan view, and FIG. 6B is a cross-sectional view taken along the line AA.

  The second fixed crushing blade 15 has a shape in which a ring 33 surrounds eight arms 31 extending radially in a tangential direction from the hub 30 at equal intervals. A pair of tabs 33 a are formed on the outer periphery of the ring 33 at intervals of 180 °. The pair of tabs 33 a function as rotation preventing means for fixing the second fixed crushing blade 15 to the hopper 3. Therefore, the pair of tabs 33a is formed as a plate body slightly narrower than the width so that the tabs 33a can be fitted in the fitting grooves 3a formed on the inner wall of the hopper 3. This width is substantially the same as the width of the tab 24 b of the first fixed crushing blade 13. The rotation of the second fixed crushing blade 15 is regulated by fitting the tab 33a into the fitting groove 3a.

  These tabs 33a have a predetermined height, and the lower tab 24b of the first fixed crushing blade 13 is in contact with the upper surface of the tab 33a, so that the first fixed crushing blade 13 and the second fixed crushing blade 15 are in contact with each other. A gap having a predetermined height is formed between them, and the size is selected so that the second rotary crushing blade 14 is just engaged. The center hole 30a of the hub 30 is dimensioned so as not to interfere with the rotation drive shaft 36.

  Of the eight arms 31, the second fixed crushing blade 15 has a comb tooth portion 31a formed on the upper surface of the six arms 31. The comb teeth portion 31a of the second fixed crushing blade 15 has a pitch that meshes with the comb teeth portion 28a of the second rotary crushing blade 14 shown in FIG. 5, and as shown in FIG. 2 When the fixed crushing blades 15 are overlapped, the comb-tooth portions 28a and 31a of both are in an engaged state in which a slight gap is formed.

  Thereby, the comb tooth portion 31a of the second fixed crushing blade 15 crushes the garbage sent from the upper crushing blade in cooperation with the comb tooth portion 28a of the second rotary crushing blade 14.

  As described above, since the number of the arms 28 of the second rotary crushing blade 14 is three and the number of the arms 31 of the second fixed crushing blade 15 is eight, the distance between the arms 31 is narrower than the distance between the arms 28.

  For this reason, when the comb tooth portions 31a are provided on all the eight arms 31, the comb tooth portions 31a of the second fixed crushing blade 15 always exist between the arms 28 of the second rotary crushing blade 14, and a certain degree When the block-shaped garbage of a magnitude | size is thrown in, the situation which the garbage does not enter between the arms 28 of the 2nd crushing blade 14 and becomes difficult to crush occurs.

  Therefore, in the second fixed crushing blade 15, among the eight arms 31, for example, the two arms 32 are not provided with the comb-tooth portion 31 a, so that the second rotary crushing blade 14 is rotated during the rotation operation. 2 When the arm 31 not provided with the comb tooth portion 31a of the fixed crushing blade 15 is positioned between the arms 28 of the second rotary crushing blade 14, a wide space is formed in the circumferential direction.

  Thereby, even when block-shaped garbage having a certain size is introduced, the garbage enters between the arms 28 of the second rotary crushing blade 14, and the comb tooth portion 28 a is rotated by the rotation of the second rotary crushing blade 14. And the garbage is crushed in cooperation with the comb tooth portion 31a of the other arm 31 of the second fixed crushing blade 15.

  In addition, since the crushing ability is reduced when the number of the arms 31 that are not provided with the comb-tooth portions 31a is large in the second fixed crushing blade 15, for example, when the eight arms 31 are provided, the arms 32 that are not provided with the comb-tooth portions 31a. As shown in the drawing, about two are preferable.

  Each arm 32 extends radially along the tangential direction of the hub 30 so that when the second rotary crushing blade 14 rotates, the meshing point with the second fixed crushing blade 15 is shifted in the circumferential direction, The crushing load peak is suppressed and the load is flattened.

  As shown in FIG. 6A, the second fixed crushing blade 15 has pressing surfaces 31 b and 32 a formed on the side surfaces located on the rotation direction side among the side surfaces of the arms 31 and 32. The pressing surfaces 31b and 32a are both wave-like wavefronts, and are formed as wavefronts having a taper whose lower end is shorter than the upper end. By making the pressing surfaces 31b and 32a into wavefronts, the garbage is captured by the concave portions having the taper, and the movement of the garbage in the radial direction is suppressed, so that the garbage can be reliably crushed.

  FIG. 7 shows an example of the third rotary crushing blade 16, where FIG. 7A is a plan view thereof, and FIG. 7B is a cross-sectional view thereof taken along the line AA.

  The third rotary crushing blade 16 is configured as a disk 35, and a large number of slits 35a are arranged on the entire surface of the disk 35 excluding the central rotary drive shaft 36. In the third rotary crushing blade 16 of this example, a plurality of slit groups are formed, and in each slit group, adjacent slits 35a are arranged substantially in parallel.

  The upper surface of the third rotary crushing blade 16 is a flat surface and rotates while contacting the bottom surface of each arm 31 of the second fixed crushing blade 15 shown in FIG. In addition, the slit 35a shown in FIG. 7 penetrates the third rotary crushing blade 16 from the front and back, and a sharp edge is formed at the opening edge of the upper surface side of the slit 35a.

  The upper surface of the third rotary crushing blade 16 rotates while rubbing against the bottom surface of the arm 31 of the second fixed crushing blade 15, but one side of the arms 31 and 32 of the second fixed crushing blade 15 is inclined to the bottom surface side. Since the wave fronts 31b and 32a are formed, the third rotary crushing blade 16 rotates the third waste crushing blade 16 in contact with the garbage (that is crushed to a certain size) in contact with the wave fronts 31b and 32a. A force for pressing the rotary crushing blade 16 can be applied.

  Garbage that has been crushed by the comb tooth portion 28a (FIG. 5) of the second rotary crushing blade 14 and the comb tooth portion 31a (FIG. 6) of the second fixed crushing blade 15 and dropped onto the upper surface of the third rotary crushing blade 16 Although caught in the slit 35a, the garbage is pressed against the slit 35a by the wave fronts 31b and 32a as the third rotary crushing blade 16 rotates. The garbage is crushed by the edge portion of the slit 35a by this rotation operation. The finely crushed food waste falls downward through the slit 35a, passes through the bottom plate 9 of the hopper 3 shown in FIG. 1, and is discharged from the drain pipe connection port 8 to the outside.

  In addition, the slit 35a forms the opening part (or opening step part) which becomes wide toward the bottom face side, so that the garbage pushed into the slit 35a easily falls.

  A rotary drive shaft 36 is integrally formed with the disk 35 at the center of the third rotary crushing blade 16. The rotary drive shaft 36 is rotationally integrated with the first and second rotary crushing blades 12 and 14, and is rotationally free with respect to the first and second fixed crushing blades 13 and 15. It is made into a shape. Therefore, the rotary drive shaft 36 corresponding to the first and second rotary crushing blades 12 and 14 is a square shaft portion (fitting shaft portion), and the rest are round shafts. And the screw part is cut in the axial head, and it is comprised so that it may function as the latching | locking part 36a.

  A fitting portion 37 that functions as a part of the rotation drive shaft 36 is provided on the lower surface of the disk 35, and is configured to be rotated and engaged with the drive shaft 10 of the reduction unit (not shown). In order for the fitting portion 37 to be in a good fitting state with the drive shaft 10, the inner hole 37a (see FIG. 2) is a square hole or a hexagonal hole. The latter is illustrated in FIG. It is assumed that the fitting length of the fitting portion 37 is selected so that the fitting portion 37 is in a sufficiently fitted state with the drive shaft 10 of the reduction unit.

  The first rotary crushing blade 12, the first fixed crushing blade 13, the second rotary crushing blade 14, the second fixed crushing blade 15 and the third rotary crushing blade 16 configured in this way are in this order as shown in FIG. The rotary drive shafts 36 that are arranged and provided in the third rotary crushing blade 16 are penetrated to be stacked with each other. Then, the crushing unit 4 with which the some crushing blades 12-16 were integrated is obtained by screwing the screw 29a from the upper end of the latching | locking part 36a which is a shaft head of the rotational drive shaft 36, and fastening. At this time, the tabs 24 of the first fixed crushing blades 13 and the tabs 33a of the second fixed crushing blades 15 are integrated in a state where their positional relationships are adjusted so that they are continuous (in a straight line).

  Then, with the tabs 24 and 33a being fitted along the fitting groove 3a, the crushing unit 4 is lowered in the hopper 3 along the fitting groove 3a. At this time, the crushing unit 4 is lowered using the grip portion 21. When the crushing unit 4 is lowered to the bottom surface of the hopper 3, the fitting portion 37 provided on the third rotary crushing blade 16 is fitted to the drive shaft 10 of the reduction unit.

  Here, the tabs 24 and 33a of the crushing unit 4 are only mounted in the fitting groove 3a, and it is not necessary to fix the tabs 24 and 33a to the hopper 3 with screws or the like. This is because the crushing unit 4 can be stably locked to the hopper 3 by using the tab 24 and the relatively short tab 33a. Thus, by extending the tab 24 relatively long, it can be reliably fixed in the hopper 3 while preventing the crushing unit 4 from rotating. Since the crushing unit 4 is merely fitted to the hopper 3, the crushing unit 4 can be easily pulled up, and cleaning of the hopper 3, the crushing unit 4, and the like is facilitated.

  As described above, in the grinder-type garbage disposal apparatus 1, the comb-tooth portions of the rotary crushing blades and the stationary crushing blades that are stacked mesh with each other with a slight interval, and the rotary crushing blades rotate to rotate the crushing blades. Crush between the blades and the comb teeth of the fixed crushing blade with a ridge.

  Now, in the garbage processing apparatus 1 in which such a crushing unit 4 is housed in the hopper 3, in the present invention, when automatic water supply is performed in association with the opening / closing operation of the opening / closing lid 11, the opening / closing lid 11 as described above. The automatic water supply is executed with a slight delay from the timing when the lock on the hopper 3 is detected.

  An example of the control means 120 is shown in FIG. The control unit 120 includes a control unit 121 including a CPU that controls the entire apparatus. The control unit 121 is supplied with a detection signal Sa from a detection sensor 6b that detects the locked state of the open / close lid 11. A drive motor 122 for driving the crushing unit 4 in association with the control signals Sb and Sc from the control unit 121 and an on-off valve (water discharge amount adjusting means) 100B connected to the branch pipe 112 shown in FIG. Is done.

  Further, in this example, the buzzer 124 and the speaker 126 that performs voice guidance are controlled as control means by the control signals Sd and Se from the control unit 121. FIG. 12 shows a case where the control signal Sf is further generated and the display means (for example, LCD) 125 is also controlled by this control. A combination use example of the notification unit 124, the display unit 125, and the speaker 126 is arbitrary.

  FIG. 9 is a timing chart showing an example of control by the control unit 121. First, when the opening / closing lid 11 attached to the hopper 3 is rotated to the lock position, the detection sensor 6b detects the lock. When the detection signal Sa when the lock of the open / close lid 11 is detected is supplied to the control unit 121, the control unit 121 determines that the open / close lid 11 is locked (FIG. 9A).

  When the lock state of the open / close lid 11 is detected, the open / close valve 100B is controlled to be in an open state (FIG. 9C) with a slight delay from this detection timing (ta = 1 to 2 seconds). Thus, the crushed water is automatically supplied into the hopper 3 through the opening / closing lid 11. Since the opening degree of the on-off valve 100B is adjusted in advance, an optimal amount of water can be supplied into the hopper 3 as the crushed water supplied automatically.

  In this way, the tap water is not automatically supplied at the same time as the opening / closing lid 11 is locked, but is automatically supplied with a slight delay, so that the operator's hand is separated from the handle of the opening / closing lid 11 and then water is supplied. As a result, it is possible to almost certainly avoid a situation in which the operator's cuffs are wetted by the tap water discharged.

  The drive motor 122 is driven after a little later than the detection timing of the opening / closing lid 11, for example, after about tb = 5 seconds from the lock detection timing (FIG. 9B). This starts the crushing process mode.

  Although the actual crushing process is started after supplying the crushed water in this way, the crushing process is not performed simultaneously with the water supply process, but the crushing process is performed after the water supply process in the hopper 3 or the crushing unit 4. This is because it becomes difficult to attach crushed food waste to the inner wall of the hopper 3 or the surfaces of the crushing blades 12 to 16 during the crushing process. Of course, the crushing process may be executed simultaneously with the water supply process.

  On the other hand, the buzzer 124 as the notification means is driven for a predetermined time (described later) at substantially the same timing as the above-described lock detection before the automatic water supply process and the crushing process described above (FIG. 9D). By driving the buzzer 124, a buzzer sound reverberates, whereby the user can reliably predict that the opening / closing lid 11 is locked and the crushing process is started subsequently. .

  When the notification process using the buzzer sound ends, the voice guidance is activated (FIG. 9E). For example, a voice guidance saying “The crushing mode has started” is performed. This makes it possible to reliably recognize whether the crushing processing mode has started or ended without making a mistake.

  The crushing time can be arbitrarily set. In this example, about 60 seconds is set as the crushing processing time (FIG. 9B). Even after the crushing process is completed, the water supply process is continued for a predetermined time (FIG. 9C). After this, the water supply is a follow-up water. In this example, about 5 seconds are secured as the follow-up water treatment. By carrying out the additional water, the crushed material adhering to the inner wall of the hopper 3 or the crushing unit 4 can be washed away. That is, the additional water is used as cleaning water.

  When the crushing process ends, the buzzer 124 is driven again, and the end of the crushing process can be confirmed by a buzzer sound (FIG. 9D). In this example, the buzzer 124 is driven even when about half of the crushing process is completed. Thus, it can be seen that the crushing process has progressed by about half, so that it is easy for the user to perform subsequent setup such as dishwashing.

  When the buzzer 124 is driven several times, it becomes impossible to determine what timing the buzzer sound is for informing. In order to avoid this, the sound can be distinguished by changing the sound transmission pattern such as the length of the sound.

  FIG. 10 shows an example thereof. As a buzzer sound for informing the start of the crushing process, for example, “beepy” is sounded three times as shown in FIG. 10A. For example, a sound is generated for 150 msec, and an interval of 500 msec is opened to drive again for 150 msec. Then, for the third time after 500 msec, a 500 msec sound is generated.

  When half of the crushing process is finished, for example, a buzzer is sounded twice as shown in FIG. 10B. The sounding time and interval are shorter than in the case of FIG. 10A. For example, it sounds at 100 msec intervals.

  When the crushing process is completed, the length of the buzzer sound for informing the end is changed even when it sounds three times as shown in FIG. 10C. For example, a sound is generated only for 200 msec, and the drive is performed again for 2000 msec with an interval of 500 msec. And for the third time after 500 msec, a long sound is made for 500 msec.

  Thus, even in the same crushing process, by adjusting the sound length and interval according to the timing, that is, the sound transmission pattern, it is easy to determine whether the crushing process has started, is in the middle, or has been completed. Recognized with certainty.

  Similar to the buzzer sound, the content of the voice guidance is changed depending on the timing of the crushing process. When the crushing process is in progress, for example, a guidance such as “Soon to be finished” is broadcast, and when the crushing process is finished, the guidance is given, for example, “The crushing process is finished”. By using this voice guidance together, it is possible to easily grasp the timing of the crushing process.

  The notification means 124 or the like may be disposed on the back side of the kitchen sink S, or may be installed in a space on the upper surface side of the kitchen sink S that does not interfere with the kitchen. In the case of using together with the LCD 125 as the display means and the speaker 126 as the sound means, it is preferably installed in the above-mentioned space. It is easier to hear.

  When the buzzer and the display are used together, as shown in FIG. 11E, by displaying on the display means 125 such as “starting crushing mode”, “coming soon”, “crushing mode is finished” It is possible to reliably grasp when the crushing process is performed. Buzzer, voice guidance and display guidance can all be performed. This is because it is possible to cope with the hearing impaired and the elderly.

  The processing from FIG. 11A to FIG. 11D is the same as the processing shown in FIG. 10A to FIG.

  The automatic water supply means 100 described above is an example, and can be applied to a faucet of a shower pull-out faucet system in which the faucet 100A is pulled out to the kitchen sink S side and can be used as a shower nozzle. As the crushing unit 4, a hammer mill type or chain mill type crushing unit can be used instead of the grinder type.

  The present invention can be used for general households such as apartment houses and detached houses, and kitchens such as restaurants.
