Abstract

Crushing water is supplied to a housing in a hopper (3). Flushing water is supplied to a trap tube (40) connected to a discharge opening of the housing. A water discharge/supply section (42) for the flushing water is connected to the trap tube. The crushing water is supplied before a crushing treatment. The supply of the flushing water is made for a predetermined period not only after the crushing treatment but also during the crushing treatment. When the flushing water is supplied to the trap tube during the crushing treatment, the water flow in the trap tube causes suction force to act on crushed objects flowed to the discharge opening of the housing and the force pushes out the objects. The suction force causes the crushed objects to be discharged to the drainage pipe side after passing all the way through the inside of the trap tube, so that a discharge efficiency is increased. After a predetermined time after the completion of the crushing treatment, flushing water for post crushing treatment is supplied, and this discharges remaining objects in the trap tube and flushes the trap tube.

Garbage disposal equipment

Technical field

The present invention relates to a garbage disposal apparatus that can be applied to kitchen facilities. Specifically, in addition to the supply of crushed water to the main body of the garbage processing device, when supplying cleaning water to the trap tube connected to the discharge side of the main body of the garbage processing device, the crushing process is not limited to after the crushing process. In addition, by supplying cleaning water, it is possible to avoid the retention of crushed material in the trap pipe.

Background art

[0002] Hammer mill type and grinder type are known as garbage disposal devices for crushing garbage used in general households and restaurants.

[0003] In the hammer mill type garbage disposal apparatus, a fixed hammer or a swingable hammer is provided on a disk disposed at the bottom of a cylindrical hopper. The garbage thrown into the hopper is pressed against the inner peripheral surface of the hopper by the centrifugal force generated by the rotation of the disk, and the garbage is broken by the hammer. The broken garbage falls down from a groove formed in the wall surface of the hopper or a gap between the outer edge of the disk and the inner peripheral surface of the hopper. The shredded garbage that has fallen is discharged to the drain pipe side.

[0004] Hammer mill type garbage processing equipment is designed to operate a high-speed disk at a speed of several thousand revolutions (rpm) to grind the garbage in the hopper. Is particularly loud and vibrant because it hits the hammer and the inner surface of the hopper and is crushed.

[0005] On the other hand, a grinder type garbage disposal apparatus uses a crushing unit in which rotating blades having comb-shaped blades and stationary blades are alternately stacked. These rotary blades and fixed blades constituting the crushing unit are held together with a slight gap, and when the rotary blades rotate, the rotary blades and the fixed blades are crushed while sandwiching garbage. The pitch between the stacked rotary blades and fixed blades becomes stronger toward the lower layers. Therefore, the garbage thrown into the hopper is first roughly crushed by the upper rotary blade and fixed blade, and the lower It is further crushed by a rolling blade and a fixed blade and discharged downward.

[0006] This grinder-type garbage disposal apparatus having a structure in which rotating blades and fixed blades are alternately stacked does not require the use of centrifugal force, so that the number of rotations can be reduced and noise can be reduced.

[0007] In such a garbage processing apparatus, there are cases where tap water used as treated water for flowing down crushed garbage is automatically supplied. In this case, treated water (hereinafter referred to as crushed water) is automatically supplied into the housing provided in the main body of the garbage processing apparatus.

[0008] When the seed garbage disposal apparatus is installed in a kitchen sink, a trap pipe is usually connected between the housing and the drain pipe. Washing water is also supplied separately from the crushed water for the purpose of discharging the accumulated matter in the trap tube and cleaning the inside of the trap tube.

[0009] By the way, in the above-described garbage processing apparatus, when automatic water supply processing and trap tube cleaning processing are performed in combination, at what timing the two processings are performed, particularly which cleaning processing is performed. Whether to do it at the timing is a problem. This is because, depending on the timing of the cleaning process, the crushed material of Hauzinaka can not be discharged effectively, or a part of the crushed material remains in the trap tube. Wash water can be wasted.

[0010] Therefore, the present invention solves such a conventional problem, and in particular, when washing water is used in addition to the crushed water, the garbage is crushed and the crushed material is washed. We propose a garbage treatment device that can avoid the retention in the trap tube by performing the water supply timing during the crushing process not only after the crushing process.

BEST MODE FOR CARRYING OUT THE INVENTION

[0014] Next, a case where the garbage processing apparatus according to the present invention is applied to a tap water supply system of a garbage processing apparatus attached to a kitchen sink will be described.

FIG. 1 shows a conceptual diagram when the present invention is applied to a tap water supply system of a garbage disposal apparatus 1 installed in a household kitchen sink.

[0016] The waste disposal device 1 is attached and fixed to the bottom surface of the drain outlet So provided at the substantially central bottom of the kitchen sink S. As will be described later, the garbage disposal apparatus 1 has a cylindrical hopper 3 and a crushing unit is provided therein. The crushing unit is driven to rotate by motor 6.

[0017] As the demolition unit, use the above-mentioned non-mer mill type that grinds the garbage using a hammer mill, or the grinder type that crushes the garbage using a fixed blade and a rotating blade. be able to. The embodiment shown below is a garbage disposal apparatus using the latter (grinder type). As shown in FIG. 1, a tap water supply port 9 and a connecting pipe 10 connected to the supply port 9 are connected to the upper peripheral surface of the hopper 3. A drain pipe connection port 21 is provided on the lower peripheral surface of the hopper 3, and crushed water used for crushing (water that flows the crushed material) is drained through the drain pipe connection port 21. Drained into tube 39.

A well-known trap pipe, for example, an S-shaped trap pipe 40 is connected between the drain pipe connection port 21 and the drain pipe 39. In this example, a branch pipe 41 is provided between the S-shaped trap pipe 40 and the drain pipe connection port 21. The branch pipe 41 is substantially T-shaped, and the first branch pipe 41a is connected to the S-shaped trap pipe 40 described above, and on the second branch pipe 41b side connected to the S-shaped trap pipe 40 in a vertical state. Is connected to a discharge water supply section 42 that functions as a discharge water supply means for the cleaning water. The discharge water supply section 42 is provided to prevent crushed material from staying in the S-shaped trap pipe 40. The discharged water stays in the pipe by supplying cleaning water to the S-shaped trap pipe 40. At the same time, the trap tube is cleaned.

[0020] In the example of FIG. 1, as the kitchen sink S, a sink provided with a stepped portion 50 located in a lower part that is recessed by one step with respect to the upper flat surface (overflow edge) Sa is used. A faucet tube 51 protrudes and is fixed to the stepped portion 50. By operating the handle 52 of the faucet pipe 51, tap water is opened and closed (stopped).

[0021] The stepped portion 50 is further provided with a vacuum break force 60 for tap water supplied to the garbage disposal apparatus 1. The vacuum breaker 60 is provided so that the tap water and the water (sewage) on the side of the garbage treatment device 1 are not directly mixed, and the tap water is introduced to the vacuum breaker 60. Then, the tap water discharged from the vacuum breaker 60 is led to the garbage disposal device 1 and the S-shaped trap tube 40.

[0022] For this reason, the vacuum breaker 60 is also a double type. The first branch pipe 53a branched from the water main pipe 53 is connected to the faucet pipe 51. The second branch pipe 53b and the third branch pipe 53c branched from the water main pipe 53 are connected to a water supply connection port (water supply port) provided in the vacuum breaker 60, respectively.

[0023] The second branch pipe 53b and the third branch pipe 53c are provided with a crushed water on-off valve 55 and a washing water on-off valve 57 to control water supply. As the crushed water on-off valve 55 and the washing water on-off valve 57, for example, electromagnetic valves are used. There is no guide between the spout associated with the second branch pipe 53b and the connecting pipe 10. A water pipe 54 is connected. It is also possible to connect directly to the tap water supply port 9 without going through the connecting pipe 10. The water outlet associated with the third branch pipe 53c is connected to the discharge water supply unit 42 described above via a water conduit 56.

[0024] By connecting the water pipes and the like in this way, the treated water (crushed water and washing water) is connected to the tap water supply port 9 and the drain port 21 side of the garbage treatment device 1 through the vacuum breaker 60, respectively. Water).

[0025] As the vacuum breaker 60, an open-air type (atmospheric pressure type) is used. Even if a negative pressure that causes an increase in the level of sewage due to water breakage acts on the drain pipe side, the vacuum break force 60 can reliably separate the water system from the sewage system.

FIG. 2 shows an example of a garbage disposal apparatus 1 to which the present invention can be applied. The garbage disposal apparatus 1 has a hopper 3. A hopper 3 into which garbage or the like is placed is mounted on the base frame 2, and the upper end of the hopper 3 is fitted to the drain port So of the kitchen sink S.

[0027] Inside the hopper 3, a crushing unit 4 is mounted so as to be detachable from the hopper 3. In the frame breaking unit 4, a rotary crushing blade described later is fitted to the drive shaft 5 a of the speed reduction unit 5, and the motor 6 attached to the base frame 2 rotates the rotation crushing blade of the crushing unit 4 via the speed reduction unit 5. . In the drive shaft 5a for transmitting the driving force to the crushing unit 4, the fitting portion with the crushing unit 4 is formed in a square shaft shape or a spline shaft shape.

[0028] The hopper 3 has a charging opening 7 formed at the upper end, and a lid 8 is detachably attached to the charging opening 7. The input opening 7 is provided with the supply port 9 described above. Tap water is supplied from the supply port 9 to the lid 8 and then supplied from the lid 8 into the hopper 3, which is used as crushed water.

[0029] The lid 8 includes an inner lid 8a and an upper lid 8b. The inner lid 8a has a cylindrical shape with an opening at the top and a bottom at the bottom. The water cover 12 protrudes from the bottom 11 and a plurality of water supply ports 13 are formed around the water pad 12. A water reservoir 11 a is formed by the water pad 12 and the water supply port 13.

[0030] The plurality of water supply ports 13 are formed on the entire surface from the inner peripheral side force to the outer peripheral side of the bottom 11 of the water storage unit 11a. The water supply ports 13 can be arranged radially, for example.

[0031] The water reservoir 11a includes a supply port 18 that penetrates the side of the inner lid 8a from the outer peripheral surface to the inner peripheral surface. Therefore, when the lid 8 is fitted into the charging opening 7, it communicates with the supply port 9 of the hopper 3. Thus, the supply port 18 is formed.

[0032] The water pad 12 is formed in a portion facing the wall surface force supply port 18 erected with respect to the bottom 11. The water pad 12 is disposed substantially perpendicular to the direction of water discharge from the supply port 18 in the lateral direction. In the vertical direction, an inclined surface is formed that is inclined in a direction in which the upper side is located on the back side. This is because the water supplied into the lid 8 is evenly dispersed around and dropped into the hopper 3.

[0033] Inside the hopper 3, a bottom plate 22 inclined toward the drain pipe connection port 21 is provided, and a hole 22a through which the drive shaft 5a of the speed reduction unit 5 passes is formed at the center of the bottom plate 22.

In this example, the lid body 8 is closed by rotating the lid body 8 in a predetermined direction by a predetermined angle while the lid body 8 is attached to the closing opening 7. When closed, the lid 8 is locked to the hopper 3. The garbage disposal apparatus 1 is in an operating state with the lid 8 locked. The locked state of the lid 8 is detected by the detection means 24 attached to the outer peripheral surface of the hopper 3. As the detection means 24, a magnetic sensor (proximity sensor) or the like is used. Therefore, a magnet (not shown) is attached and fixed to the lid 8 at a corresponding position.

The garbage disposal apparatus 1 includes a control unit (control means equipped with a CPU) 25 that controls the rotational drive of the motor 6. The control unit 25 opens and closes the crushed water on / off valve 55 and the rinsing water on / off valve 57 according to the detection signal from the detecting means 24 and the control signal generated based on the internal clock, and starts the rotation of the motor 6 and Control stop etc. Also, the buzzer 70 and speaker 72 are driven according to the opening / closing control of the crushing water on / off valve 55 and the rinsing water on / off valve 57. The

[0036] In this example, a crushing blade similar to the structure disclosed in Japanese Patent Application Laid-Open No. 2004-298809 is used as the crushing unit 4 mounted in the housing 31. Therefore, the crushing unit 4 is used as a unit in which the first rotary crushing blade 26, the second fixed crushing blade 27, the third rotary crushing blade 28, the fourth fixed crushing blade 29, and the fifth rotary crushing blade 30 are overlapped. Is done.

[0037] Nozzle 31 is cylindrical and has an outer diameter substantially equal to the inner diameter of hopper 3. The crushing unit 4 is also equipped with the loading opening 7 side force of the hopper 3. The winging 31 is provided with a detachable handle 31c made of a circular metal rod. The handle 31c is attached to the upper end side of the housing 31 so as to extend in the diameter direction. [0038] The first rotary crushing blade 26 is composed of a single stirring arm extending horizontally from one side of the side portion of the bearing portion 32.

[0039] The second fixed crushing blade 27 includes two flat arms extending horizontally at intervals of 180 degrees, and the edges formed on both side surfaces thereof function as crushing blades.

[0040] The third rotary crushing blade 28 includes three arms extending radially from the center at intervals of 120 degrees. Each arm is formed with a comb tooth portion having a predetermined pitch on the bottom surface side.

[0041] The fourth fixed crushing blade 29 has a shape in which eight arms extending radially in the tangential direction at equal intervals are surrounded by a ring. Of the eight arms, for example, six arms have comb teeth formed on the upper surface thereof that mesh with the third rotary crushing blade 28, and these mesh with the third rotary crushing blade 28. The comb tooth portion of the fourth fixed crushing blade 29 crushes the garbage sent from the upper crushing blade cap in cooperation with the comb tooth portion of the third rotary crushing blade 28.

[0042] Tabs 29a projecting radially at intervals of 180 degrees are formed on the outer periphery of the ring. The tab 29a is fitted in the longitudinal groove 3 lb of the housing 31 to restrict the rotation of the fourth fixed crushing blade 29.

[0043] The fifth rotary crushing blade 30 has a disk shape, and is configured by arranging a large number of slits on the entire surface except the central hub. In this example, it is composed of a plurality of slit groups, and adjacent slit groups are arranged substantially in parallel.

The upper surface of the fifth rotary crushing blade 30 is a flat surface, and rotates while being in contact with the bottom surface of each arm of the fourth fixed crushing blade 29. Further, the slit penetrates the fifth rotary crushing blade 30 from the front and back, and a sharp edge is formed at the opening edge of the upper surface side of the slit. Therefore, the garbage that has been crushed by the comb teeth of the third rotary crushing blade 28 and the comb teeth of the fourth fixed crushing blade 29 and dropped onto the upper surface of the fifth rotary crushing blade 30 is caught in the slit, and the fifth rotation. As the crushing blade 30 rotates, it is pressed against this slit and crushed by the edge portion of the slit. The finely crushed garbage is dropped together with crushed water through the slit, passes through the bottom plate 22 of the hopper 3 and is discharged from the drain pipe connection port 21 to the outside.

[0045] In relation to the opening / closing operation of the lid 8, the crushed water on / off valve 55 and the rinsing water on / off valve 57 are controlled to control the supply of water to the crushed water and the rinsing water. The water supply control is control of crushed water into the housing 31 and cleaning water control to the S-shaped trap tube 40. The water supply control is performed by the control unit 25 based on a detection signal from the detection means 24 and the like. The control unit 25 has a tie inside. It is assumed that it has a digital function (counter function).

[0046] Next, an example of this water supply control will be described with reference to FIG. When the crushing process is performed, the crushed material is discharged at the same time. Tb is the crushing / discharging process time during which the crushing process and the discharging process proceed simultaneously. In order to enhance the crushing effect even after the crushing process is completed, an example is shown in which crushing 'discharge processing is continued for a predetermined time Tc. These processing times and predetermined times may be expressed as processing periods or predetermined periods for convenience of explanation.

In this example, the crushing and discharging process times Tb and Tc are set to substantially the same time. If these processing times Tb and Tc are set too short, the crushing and discharging processes will be insufficient, and conversely if too long, the processing time and power will be wasted. According to various experiments, it was found that the treatment times Tb and Tc are preferably about 30 to 40 seconds, and about 60 to 70 seconds in total.

[0048] Of course, the crushing / discharging treatment time Tb can be set to a long time, and the subsequent crushing / discharging processing time Tc can be set to be short so that the total processing time can be set to be the same. . For example, when the total processing time (Tb + Tc) = 60 seconds, Tb = 40 seconds and Tc = 20 seconds. In the description of FIG. 3, Tb = 30 seconds and Tc = 30 seconds are set. This will be described with reference to FIG.

[0049] At the stage when the garbage is dropped into the woozing 31, the lid 8 is attached to the opening 7. After installation, the lid body 8 is locked to the hopper 3 by rotating the lid body 8 in a predetermined direction by a predetermined angle (A in FIG. 3 and B in FIG. 3, time points tl to t2). Since the detection means 24 is provided at the lock position of the hopper 3, the proximity and separation of the lid 8 are detected by the detection means 24.

[0050] Based on the signal from the detection means 24, the control unit 25 generates a lock detection signal (closeness of the lid 8) and an unlock signal (separation of the lid 8) (C in FIG. 3). , Time t2, t9).

[0051] When the lock detection signal is generated, the crushed water opening / closing valve 55 is first controlled to open by the control signal from the control unit 25 (D in FIG. 3, time point t2). As will be described later, the crushed water on-off valve 55 is continuously controlled to be in the open state from time t2 to time t7 (Tx). When the crushed water open / close valve 55 is opened, crushed water is supplied to the lid body 8 through the water supply port 9, so that crushed water is introduced into the housing 31 from the water supply port 13 provided at the bottom of the lid body 8. Water is supplied (Ε in Fig. 3) [0052] The reason for pre-watering for a predetermined time Ta immediately before the start of the crushing process is to smoothly wet the inner wall of the housing 31 and the surface of the crushing unit 4 with the crushed water. It is possible to prevent garbage from adhering to these members during the subsequent crushing process. Therefore, the time Ta for this preliminary water supply should be set to about 5 seconds.

[0053] When this pre-water supply time elapses, a full-scale crushing process is performed while water supply continues (G in FIG. 3, time t3-). Accordingly, the drive motor 6 is energized from time t3, and the rotary crushing blades 26, 28, 30 of the crushing unit 4 are driven to rotate (F in FIG. 3). The crushing process for garbage proceeds with the cooperation of the rotary crushing blade and the fixed crushing blade. During the crushing and discharge process (period Tb) in which crushing and discharge are performed at the same time, crushed water is supplied. Is accelerated.

[0054] Immediately after the crushing and discharging process is started, the crushing is sufficiently advanced! /,!, So that the crushed material does not fall from the fifth rotary crushing blade 30 to the bottom plate 22 side. Experiments confirmed that when the crushing process progresses and the garbage is crushed to a certain degree of fineness, the finely crushed crushed material begins to fall from the fifth crushing blade 30 to the bottom plate 22 side. . Therefore, the first half of the crushing / discharge period Tb (about 10-15 seconds after the start of crushing) is almost only crushing treatment, and after that, almost constant amount of crushed material falls to the bottom plate 22 side and is discharged. The

[0055] Therefore, in this example, the process shifts to a process for assisting the discharge process of the crushed material from the time t4 when a predetermined time Δt (for example, 15 seconds) has elapsed after the start of the crushing. That is, the supply of cleaning water to the S-shaped trap tube 40 is started. Therefore, the cleaning water on-off valve 57 is controlled to be in the open state and cleaning water is supplied (J in Fig. 3 and K in Fig. 3).

[0056] Thereby, the washing water is supplied to the S-shaped trap pipe 40 side, and acts on the crushed material flowing down from the bottom plate 22 through the drain pipe connection port 21 to the first branch pipe 41a of the branch pipe 41. The washing water at this time will help the crushed material flow down, and the crushed material will be discharged more smoothly. The crushed material is discharged to the drain pipe 39 side through the S-shaped trap pipe 40.

[0057] The discharge process assistance period Td can be set to any time, but in this example, the discharge process assistance period Tb is set to a time of about 10 seconds in order to end the discharge process assistance. The

[0058] After the crushing and discharging process (period Tb) is completed, the crushing and discharging process (period Tc) continues (G in Fig. 3). According to various experiments, it has been found that the crushing of the general garbage put into the hopper 3 is almost completed during the period Tb of the crushing and discharging process. Therefore, during the crushing / discharging treatment time Tc, the drive motor 6 may be stopped and only the wastewater treatment may be performed by supplying only the crushed water opening / closing valve 55 with equal power.

[0059] Here, a large amount of garbage that is difficult to crush, such as those rich in fiber, bones, and shells, is input as garbage, and all crushing is performed in the crushing 'discharge process (period Tb). Considering that it may not be completed, after the crushing and discharging process (period Tb), the drive motor 6 is continuously operated and water is supplied from the crushing water on-off valve 55 to crush and discharge. Processing (period Tc) is set (F in Figure 3). The buzzer 70 informs the user that the process has shifted to the discharge process (H in Fig. 3, time t6). In this example, voice guidance is performed simultaneously (I in Fig. 3, time t6). For voice guidance, a simple message such as “Discarding of crushed material” is sufficient. Either a buzzer sound or a voice plan that does not execute both a buzzer sound and voice guidance may be used.

[0060] The crushing process is a force that almost ends in the crushing / discharge process period Tb. In the case of the above-mentioned hard-to-crush garbage, a part of the crushed material may remain in the housing 31. In addition, a part of the crushed material may remain attached to the inner wall of the housing 31 or the crushing unit 4 by the crushing process in the period Tb. Therefore, the residual treatment and the cleaning treatment are performed simultaneously using the second half period Tc. Therefore, crushed water is also supplied during the latter half of the period Tc.

[0061] The crushing and discharging process period Tc in the latter half is supplied when the crushing and discharging process is continued when the crushing process is not completed in the period Tb and when the crushing process is completed. Dispersion of crushed water into the interior of the housing 31 by the crushing unit 4 makes it possible to dispose of the residue on the inner wall of the housing 31 and the crushing unit 4, and cleaning of the inner wall of the housing 31 and the crushing unit 4. The processing can be performed almost certainly.

[0062] At time t7 when the crushing / discharge process period Tc ends, the crushing water on-off valve 55 is controlled to be closed, and the supply of crushing water is stopped (D, E, G in Fig. 3). At the same time, washing water is opened and closed The valve 57 is controlled to be in the open state, and is supplied to the cleaning hydraulic trap tube 40 side for a short time Te (for example, 5 seconds) from the time t7. Since the cleaning water is discharged and supplied into the S-shaped trap tube 40 (K in Fig. 3, time points t7 to t8), the crushed material staying in the S-shaped trap tube 40 is discharged all at once, and at the same time the inside of the tube is cleaned Is done.

[0063] At almost the same time as the start of the cleaning process (time point t7), the buzzer 70 is called again and voice guidance is provided. The voice guidance may be a simple message such as “garbage disposal finished”. By using the buzzer sound and voice guidance in this way, the user who is away from the kitchen can reliably recognize the end of the garbage disposal.

[0064] When the garbage disposal apparatus 1 is used again, the lock of the lid body 8 is released at an arbitrary time point t9 thereafter, and the lid body 8 is removed (see Figs. 3A and 3). B, time tlO), the lid 8 may be attached.

[0065] During the crushing process, the crushed material is uniformly dropped with the crushed water to the bottom plate 22 side and discharged, and the crushed material is discharged to the drain pipe 39 side without being retained by the supply of washing water during the crushing process. Is done. Since the crushed material is discharged evenly in this way, there is no possibility that the drainage pipe 39 is clogged by the crushed material.

Meanwhile, in the control unit 25, a lock detection signal and a lock release signal are generated in synchronization with the detection of the proximity and separation of the lid 8 by the detection means 24 as shown in C of FIG. The energization of the drive motor 6 is started by the lock detection signal, and the energization of the drive motor 6 is released by the lock release signal.

[0067] The example in Fig. 3 is an example in which the lock of the lid 8 is released at the stage where all the processes (crushing / discharging process) are completed (time point t9). The drive motor 6 is de-energized at the time before being driven!

[0068] When the drive motor 6 is energized, for example, when the lid 8 is forcibly released during the rupture / discharge process period Tb that has entered the assist time Td with cleaning water, As shown in the figure, a lock release signal is generated in synchronization with the separation of the lid 8 at that time, and at this time, energization of the drive motor 6 is forcibly stopped (B, C, D, F in Fig. 4). ).

[0069] As a result, even during the crushing and discharging process, the crushing and discharging process is forcibly stopped (G in Fig. 4). After that, only the flush water open / close valve 57 is opened, and the process proceeds to the discharge process using flush water only. (J in Figure 4 and K in Figure 4). This is because even if it is part of the crushed material, if there is crushed material that is crushed by force, these will be discharged.

[0070] When the garbage disposal is forcibly terminated, a buzzer is sounded and voice guidance is provided (Η in Fig. 4 and 1 in Fig. 4). In this case, the voice guidance is performed, for example, “The garbage processing has been forcibly terminated”, so that the processing result by operating the lid 8 is notified.

[0071] When the lid 8 is mounted again and locked, the state returns to the initial state. Therefore, the process of Fig. 3 is started from the first routine, and the crushing and discharging process proceeds.

[0072] The supply amount of washing water and crushed water described above is suitably about 8 liters Zmin. However, the amount of crushed water at the time of prior water supply (time Ta) and the amount of rinsing water after discharge treatment and cleaning treatment (time Te) must be as large as during crushing and discharge treatment. Absent. Therefore, in this example, considering water saving, the crushed water on-off valve 55 and the rinsing water on-off valve 57 are controlled so that the amount of crushed water and washing water is approximately half that of the crushed and discharged water.

It should be noted that the cleaning water supplied from the discharge water supply unit 42 may be discharged as it is or may be ejected as a jet water stream.

Industrial applicability

The garbage disposal apparatus according to the present invention is extremely suitable when applied to a garbage disposal apparatus used for household kitchen sinks and the like.
