Description

[Technical field]

[0001] The present disclosure relates to a disposer water supply system and a disposer water supply method. [Background technology]

[0002] For example, Patent Document 1 discloses a configuration for supplying water to a disposer. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2021-20166 A Summary of the Invention [Problem to be solved by the invention]

[0004] As an example, in an automatic type disposer that automatically supplies water and automatically stops operation when the disposer is turned on, grinding and water supply begin simultaneously when the disposer starts operating. Therefore, for example, if the water supply time is extended, the disposer's grinding time will also be extended accordingly, and the motor noise during grinding will be generated for a long period of time.

[0005] For example, in a drainage system equipped with a siphon drain pipe, if the horizontal pipe of the siphon drain pipe is long, it takes a long time for the siphon to start up, and the total drainage time becomes longer, which in turn increases the time that the disposer motor noise is generated, leaving room for improvement.

[0006] The present disclosure takes into consideration the above and aims to provide a disposer water supply system and a disposer water supply method that can shorten the time during which a disposer's motor noise is generated when the horizontal pipe of the siphon drain pipe is long. [Means for solving the problem]

[0007] The disposer water supply system of the first aspect is a disposer water supply system comprising a disposer, a horizontal pull pipe provided downstream of the disposer and extending laterally, and a siphon drain pipe comprising a vertical pipe extending downward from the downstream end of the horizontal pull pipe, wherein the disposer has a motor that rotates a crushing member that crushes food waste, a water supply device that supplies water into the disposer, and a control device that controls the motor and the water supply device, and the control device controls the water supply device to supply water into the disposer's chamber before rotating the motor, controls the motor to rotate the motor after a first predetermined time has elapsed since the start of water supply, and controls the water supply device and the motor to stop the water supply and stop the rotation of the motor after a second predetermined time has elapsed since the start of water supply.

[0008] In the disposer water supply system according to the first aspect, the food waste put into the disposer can be crushed by a crushing member rotated by a motor, and the crushed food waste can be discharged from the disposer together with water supplied from the water supply device. The wastewater discharged from the disposer can be discharged through a siphon drain pipe.

[0009] To crush kitchen waste using the disposer water supply system according to the first embodiment, first, the kitchen waste is placed inside the disposer.

[0010] The control device controls the water supply device to supply water to the interior of the disposer before rotating the motor, controls the motor to rotate and start grinding kitchen waste after a preset first predetermined time has elapsed from the start of water supply, and controls the water supply device and the motor to stop water supply and stop motor rotation after a preset second predetermined time has elapsed from the start of water supply.

[0011] When water is supplied to the disposer, the water discharged from the disposer flows into the siphon drain pipe, filling the horizontal pipe with the water, and when the full water falls down the vertical pipe, a siphon force is generated, and the water on the upstream side of the vertical pipe is pulled towards the vertical pipe. The generation of siphon force allows for efficient drainage.

[0012] If the length of the horizontal pipe is long due to the size of the kitchen or the layout of the plumbing fixtures, it takes time for the water discharged from the disposer to reach the vertical pipe, and the time it takes for the siphon force to be generated, i.e., the time when the siphon starts to work, becomes longer, requiring longer water supply and drainage times. Therefore, in the case of a conventional system in which water is supplied to the disposer and the motor is rotated at the same time, the motor rotation time also becomes longer as the water supply becomes longer.

[0013] In the disposer water supply system of the first embodiment, water is supplied into the disposer's chamber before the motor is rotated, the motor is rotated after a first predetermined time has elapsed since the start of water supply, and water supply and motor rotation are stopped after a second predetermined time has elapsed since the start of water supply.

[0014] In this way, in the disposer water supply system according to the first aspect, the water supply is started in advance and the start of rotation of the motor is delayed, thereby shortening the motor rotation time from the start of water supply to the stop of water supply, and shortening the time during which the motor noise occurs. In addition, by starting the water supply in advance, the time lag from when the wastewater containing crushed materials is discharged from the disposer to when the siphon starts is shortened, making it possible to drain the water by making use of the transport capacity of the siphon drainage.

[0015] In the second aspect of the disposer water supply system, in the disposer system of the first aspect, the first specified time is a time longer than the time it takes for water discharged from the disposer after supplying water to the disposer's interior to reach and fall down the vertical pipe.

[0016] In the disposer water supply system of the second embodiment, the time required for the water discharged from the disposer after supplying water to the disposer's interior is longer than the time it takes for the water to reach the upright pipe and fall, so that the wastewater containing crushed kitchen waste is discharged from the disposer after siphon force is generated, thereby allowing the wastewater containing kitchen waste to be discharged efficiently.

[0017] The third aspect of the water supply method for a disposer is a water supply method for a disposer water supply system including a disposer that rotates a grinding member using a motor and supplies water to the interior of the disposer, and a siphon drain pipe that is provided downstream of the disposer and extends laterally, and includes a vertical pipe extending downward from the downstream end of the horizontal pipe, and includes a water supply step of starting water supply to the interior of the disposer before rotating the motor, a motor rotation step of rotating the grinding member with the motor to grind the kitchen waste in the interior after a first predetermined time has elapsed since the start of water supply, and a stopping step of stopping the water supply and the rotation of the motor after a second predetermined time has elapsed since the start of water supply.

[0018] In the disposer water supply method according to the third aspect, in the water supply step, water supply to the interior of the disposer is started before the motor is rotated. The wastewater discharged from the disposer flows into the siphon drain pipe.

[0019] In the motor rotation process, the motor rotates the crushing member to crush the food waste in the container after a first predetermined time has elapsed since the start of water supply. The wastewater containing the crushed food waste is discharged from the disposer to the siphon drain pipe.

[0020] In addition, the wastewater discharged from the disposer flows into the siphon drain pipe, filling the horizontal pipe with the wastewater. When the full wastewater falls inside the vertical pipe, a siphon force is generated, and the wastewater on the upstream side of the vertical pipe is pulled toward the vertical pipe, allowing for efficient drainage.

[0021] In the stopping step, the water supply and the rotation of the motor are stopped after a second predetermined time has elapsed since the start of water supply.

[0022] In the disposer water supply method according to the third aspect, the water supply is started in advance and the motor rotation start is delayed, thereby shortening the motor rotation time from the start of water supply to the stop of water supply, and shortening the time during which the motor noise occurs. In addition, by starting the water supply in advance, the time lag from when the wastewater containing crushed materials is discharged from the disposer to when the siphon starts is shortened, making it possible to drain the water by making use of the transport capacity of the siphon drainage. Effect of the Invention

[0023] As described above, according to the disposer water supply system and disposer water supply method disclosed herein, the time during which the disposer motor noise is generated can be shortened when the horizontal pipe of the siphon drain pipe is long. [Brief description of the drawings]

[Diagram 3] FIG. 2 is a block diagram showing a configuration of a control device. [Figure 4] 4 is a flowchart illustrating a control according to the embodiment. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0025] 1 to 4, a disposer water supply system 10 according to one embodiment of the present disclosure will be described.

[0026] In each figure, the directions indicated by the arrows X and Y are directions along the horizontal plane and are perpendicular to each other. The direction indicated by the arrow Z is a direction along the vertical direction (up and down direction). The directions indicated by the arrows X, Y, and Z in each figure are assumed to be mutually consistent.

[0027] <Siphon drainage system> The overall configuration of a disposer water supply system 10 according to this embodiment is shown in a schematic diagram in Figure 1. The disposer water supply system 10 according to this embodiment is equipped with a siphon drainage system 8 that efficiently discharges wastewater from a plumbing fixture 20 by utilizing siphon force.

[0028] The siphon drainage system 8 is used, for example, in a multi-story apartment building, and is equipped with a standpipe 12 that drains wastewater downward. The standpipe 12 extends in the up-down direction (vertical direction) of the apartment building, and penetrates the slabs 14 of each floor of the apartment building.

[0029] Each unit on each floor of the apartment building is provided with a plumbing fixture 20. One example of the plumbing fixture 20 is a kitchen sink, with a garbage disposer 22 and a drain trap 24 connected to the downstream side in the drainage direction.

[0030] (Configuration of Siphon Drainage System) An L-shaped piping member 26 bent into an L shape is disposed downstream in the drainage direction of the drain trap 24. The L-shaped piping member 26 includes a vertical section 26A connected to the drain trap 24 and extending vertically, a horizontal section 26B disposed horizontally on the slab 14 and extending horizontally, and a curved section 26C connecting the vertical section 26A and the horizontal section 26B.

[0031] A horizontal pipe member 28 is disposed on the slab 14 on the downstream side in the drainage direction of the L-shaped piping member 26. The horizontal pipe member 28 extends horizontally, that is, perpendicular to the vertical direction, on the slab 14. The L-shaped piping member 26 and the horizontal pipe member 28 are connected via a joint 30.

[0032] A curved drop pipe 32 is connected to the downstream end in the drainage direction of the horizontal pull pipe member 28 via a joint 34. A vertical pipe member 36 extending downward is connected to the downstream side of the drop pipe 32 via a joint 38. The downstream side of the drop pipe 32 is inserted into a through hole 14A formed in the slab 14.

[0033] The downstream end of the vertical pipe member 36 in the discharge direction is connected via a joint 42 to a junction joint 40 attached to the middle part of the vertical pipe 12 .

[0034] In this embodiment, the piping portion arranged horizontally on the slab 14, specifically the horizontal section 26B of the L-shaped piping member 26 and the horizontal pipe member 28, are the horizontal pipe 46 of the siphon drain pipe 44. From the viewpoint of ensuring drainage performance, the horizontal pipe 46 may be provided with a water gradient that slopes downward from the joint 30 toward the joint 34. In this embodiment, "horizontal" includes a slope of about the water gradient.

[0035] In this embodiment, the downwardly extending upright pipe member 36 serves as a upright pipe 48 of a siphon drain pipe 44 .

[0036] (Disposer configuration) The mechanical configuration of the disposer 22 of this embodiment is the same as that of a disposer of a general structure with a fully automatic water supply system. Inside the hopper 50 into which the kitchen waste is put, a crushing member 54 is provided, which is rotated by a motor 52 and includes a cutter for crushing the kitchen waste. In addition, a water supply pipe 56 for supplying water to the inside of the hopper 50 is connected to the hopper 50. A water pipe (not shown) drawn out as a water supply path separate from the kitchen sink faucet is connected to the water supply pipe 56. An electromagnetic valve 57 is provided in the water supply pipe 56, and water is supplied to the inside of the hopper 50 by opening the electromagnetic valve 57. The water supply pipe 56 and the electromagnetic valve 57 are examples of the water supply device of the present disclosure. The electromagnetic valve 57 and the motor 52 are controlled by a control device 61 provided in the disposer 22.

[0037] As shown in FIG. 3, the control device 61 includes a central processing unit (CPU) 61A, a read only memory (ROM) 61B, a random access memory (RAM) 61C, an interface 61D, and the like. Each component is connected to be able to communicate with each other via a bus 61E. The control device 61 also includes a storage unit 61F. For example, a hard disk drive (HDD), a solid state drive (SSD), a flash memory, or the like is used as the storage unit 61F. The storage unit 61F stores a control program for controlling the solenoid valve 57 and the motor 52, which will be described later, and various data. The control program and various data may be stored in the ROM 61B.

[0038] In this embodiment, a disposer operation processing program is stored as a part of the control program. In addition, a first predetermined time T1, a rotation time T2, a predetermined stop time T3, and a second predetermined time T4 are stored as data used in this processing. The first predetermined time T1, the rotation time T2, the predetermined stop time T3, and the second predetermined time T4 will be described later.

[0039] 1, an opening / closing lid 58 is removably attached to the opening of the hopper 50. When the disposer 22 is in use, the opening side of the hopper 50 is closed by the opening / closing lid 58, and the crushed kitchen waste such as food waste is prevented from scattering toward the kitchen sink during disposal.

[0040] The disposer 22 is configured to start operation in conjunction with the opening and closing lid 58. After the opening and closing lid 58 is attached to the opening of the hopper 50 to close the opening, the power switch 62 of the disposer 22 is turned on by rotating the opening and closing lid 58, and operation is started. The disposer 22 is provided with a control device 61 that controls the solenoid valve 57 and the motor 52 so that operation automatically stops after a preset predetermined time has elapsed.

[0041] The mechanical configuration of the disposer 22 of this embodiment is conventionally known, but the timing of starting the water supply and starting the rotation of the motor 52 is different from that of the conventional technology. The timing of starting the water supply and starting the rotation of the motor 52 will be described next.

[0042] (Action, effect) Next, the operation and effect of the disposer water supply system 10 of the embodiment will be described with reference to the flowchart of the disposer operation processing program in FIG.

[0043] (1) In the disposer water supply system 10 of the embodiment, when the power supply of the disposer 22 is turned on (step 100), an open command is output to the solenoid valve 57. This causes water supply to the hopper 50 to begin (step 102, the water supply process of the present disclosure). At this time, the motor 52 does not rotate, and only water supply is performed. Note that a certain amount of water is stored in the hopper, and the supplied water is discharged from the disposer 22 through the hopper 50. This water supply is an example of the water supply process of the present disclosure.

[0044] (2) In step 104, the process waits until a preset time (first preset time T1 in the present disclosure) has elapsed, and when the preset time has elapsed, the process proceeds to step 106 (motor rotation step in the present disclosure) and outputs a rotation command to the motor 52. This rotates the motor 52, the rotating crushing member 54 crushes the food waste, and the crushed food waste is discharged from the disposer 22 together with the water in the hopper 50. In this way, by starting the water supply in advance, the time lag between the discharge of wastewater containing crushed food from the disposer 22 and the activation of the siphon is shortened, making it possible to make use of the transport capacity of the siphon drainage. This rotation of the motor 52 is an example of a motor rotation process of the present disclosure.

[0045] Here, the timing when the siphon starts with (only) the water discharged from the disposer 22 can be set as the first predetermined time T1, but the first predetermined time T1 may be before or after the timing when the siphon starts. By setting the timing when the siphon starts (the timing when the water falls down the upright pipe 48) or a timing slightly delayed after the siphon starts as the first predetermined time T1, it becomes possible to efficiently discharge the wastewater containing the crushed kitchen waste using the siphon force.

[0046] In addition, as the crushing member 54 rotates, the amount of water discharged increases instantaneously, forcing the water in the hopper 50 into the siphon drain pipe, facilitating the activation of the siphon and enabling efficient water discharge.

[0047] (3) In step 108, it is determined whether the motor 52 has rotated for a predetermined rotation time T2, and when the predetermined rotation time T2 has elapsed since the motor 52 started to rotate, an instruction to stop the motor 52 for a predetermined time (predetermined stop time T3) is output (step 110, the stop step of the present disclosure). Since the supply of water continues while the motor 52 is stopped, a certain amount of the supplied water is stored in the hopper 50.

[0048] In the next step 112, it is determined whether the motor 52 has been stopped for a predetermined stop time T3, and after the predetermined stop time T3 has elapsed since the motor 52 stopped, the process proceeds to step 114, where an instruction is given to restart the rotation of the motor 52. This restarts the operation of the motor 52, and the crushing member 54 rotates.

[0049] After the motor 52 has rotated, the process proceeds to step 116, where it is determined whether or not the second predetermined time T4 has elapsed. If it is determined that the predetermined time T4 has elapsed, the process proceeds to step 118, where the rotation of the motor 52 and the water supply are stopped. That is, the rotation of the motor 52 and the water supply are stopped after the second predetermined time T4 from when the power is turned on. Note that, although the rotation of the motor and the water supply are stopped, the water remaining in the siphon drain pipe is pulled by the siphon and discharged.

[0050] However, after the water supply starts, the siphoning may be interrupted a while after the first siphoning occurs. However, as described above, by temporarily stopping the rotation of the motor 52 and then driving the motor 52 to rotate the crushing member 54, the water stored in the hopper 50 is pushed downstream, the amount of drainage increases instantaneously, and the siphoning can be easily started. The water pushed into the siphon drain pipe is filled up and allowed to flow into the vertical pipe, causing the siphoning to occur again, and the drainage remaining in the siphon drain pipe after the water supply stops can be efficiently discharged into the vertical pipe 12.

[0051] In the disposer water supply system 10 of this embodiment, water is supplied into the hopper before the motor 52 starts to rotate, in other words, the motor 52 is rotated to crush the kitchen waste after a preset time has elapsed since the start of water supply. Therefore, the disposer water supply system 10 of this embodiment can perform drainage making use of the conveying capacity of siphon drainage, and further, since the rotation time of the motor 52 can be shortened compared to when the motor 52 is rotated at the same time as the start of water supply to crush the kitchen waste, the time during which the motor noise is generated can be shortened.

[0052] In the control of the disposer water supply system 10, steps 110 to 114 (temporarily stopping the motor 52) may be provided as necessary, and may not be required. In this embodiment, the motor 52 is temporarily stopped in step 110, and the rotation of the motor 52 is resumed after a predetermined stop time T3. This provides the effect that the water stored in the hopper 50 is pushed downstream by the rotation of the crushing member 54, making it easier for the siphon to start.

[0053] As an example, the timing when the siphon starts with (only) the water discharged from the disposer 22 can be set as the first predetermined time, but the first predetermined time may be before or after the timing when the siphon starts. By setting the timing when the siphon starts (the timing when the water falls down the upright pipe 48) or a timing slightly delayed after the siphon starts as the first predetermined time, the wastewater containing the crushed kitchen waste can be efficiently discharged using the siphon force. In addition, as the crushing member 54 rotates, the water in the hopper is forcibly pushed into the siphon drain pipe, facilitating the activation of the siphon and enabling efficient drainage.

[0054] The first predetermined time is preferably equal to or longer than the time it takes for the water discharged from the disposer 22 after the water has been supplied into the hopper 50 of the disposer 22 (after passing through the water supply) to reach the upright pipe 48 and start to fall. The siphon force is generated when the water discharged from the disposer 22 reaches the upright pipe 48 and falls. Therefore, if the motor 52 is rotated to discharge wastewater containing crushed kitchen waste from the disposer 22 at the timing when the siphon force is generated or after the siphon force is generated, the wastewater containing the crushed kitchen waste can be efficiently discharged by the siphon force by rotating the motor 52 and pushing it out. In addition, T2 is set taking into consideration the time required for all of the kitchen waste in hopper 50 to be crushed and discharged from hopper 50, T3 is set taking into consideration the time required for a certain amount of water to accumulate in hopper 50, and T4 is set taking into consideration T1, T2, T3, and the rotation time of the motor started in step 114 (in other words, the time required to push the water in hopper 50 downstream and make it easier to start the siphon).

[0055] [Test example] A comparative test was conducted on the disposer water supply system of the embodiment to which the present disclosure is applied, the disposer water supply system of Comparative Example 1, and the disposer water supply system of Comparative Example 2.

[0056] The test will be described with reference to the timing chart in Figure 2. In the timing chart in Figure 2, the horizontal axis indicates the elapsed time (SEC) from the start of operation of the disposer.

[0057] The disposer water supply system of Comparative Example 1 and the disposer water supply system of Comparative Example 2 have the same system configuration as the disposer water supply system of the embodiment, but the length of the horizontal pipe is set to 14 m in the disposer water supply system of Comparative Example 1, and the length of the horizontal pipe is set to 20 m in the disposer water supply system of Comparative Example 2 and the disposer water supply system of the embodiment. Also, the timing of water supply and motor rotation is different in each of the disposer water supply systems of Comparative Example 1, Comparative Example 2, and the embodiment.

[0058] The disposer will ensure the minimum operating time required to crush all kitchen waste placed inside the cabinet (for example, the motor will rotate for 65 seconds).

[0059] Comparative Example 1 First, the disposer water supply system of Comparative Example 1 will be described.

[0060] (1) To crush food waste and other kitchen waste using a disposer, first put the food waste into the hopper, close the opening of the hopper with the opening / closing lid, and then rotate the opening / closing lid in the specified direction and turn on the disposer.

[0061] In a disposer, the time it takes to finish crushing the food waste placed inside the hopper (in other words, the time it takes for the motor to rotate, which is determined by the disposer manufacturer) is predetermined, and the water supply time is also predetermined based on the motor rotation time.

[0062] When the disposer power switch is turned on (0 sec on the horizontal axis), water starts to be supplied to the hopper, the motor rotates, and water starts to be discharged from the disposer. The motor stops once at 65 seconds, stops for 10 seconds, and then rotates again for 5 seconds from 75 seconds before stopping. Thus, in the disposer water supply system of Comparative Example 1, the motor rotation and water supply stop 80 seconds after the power is turned on, but after 80 seconds, the water remaining in the siphon drain pipe is pulled by the siphon and discharged.

[0063] The disposer used here has the capacity to crush all the food waste in the hopper within 65 seconds by rotating the motor, and to discharge the crushed food waste together with the supplied water from the hopper.

[0064] In addition, water continues to be supplied to the disposer for up to 80 seconds, but after a while, the wastewater that has filled the horizontal pipe reaches the vertical pipe, and as the full wastewater falls inside the vertical pipe, a siphon force is generated, and the wastewater upstream of the vertical pipe is sucked into the vertical pipe, allowing for efficient drainage.

[0065] Comparative Example 2 Next, the operation of the disposer water supply system of Comparative Example 2 will be described.

[0066] In the system of Comparative Example 2, the length of the horizontal pipe is, for example, 20 m, which is longer than that of the system of Comparative Example 1, so the siphon starts up slower than in the system of Comparative Example 1. Therefore, the water supply time and the motor operation time are also longer than those of Comparative Example 1.

[0067] When the disposer's power switch is turned on, water begins to be supplied to the hopper and the motor begins to rotate; the motor rotates until 45 seconds, then stops for 10 seconds from 45 to 55 seconds, rotates again from 55 to 105 seconds, and then stops from 105 to 115 seconds.

[0068] In Comparative Example 2, the horizontal pipe is long at 20 m, so the water supply time is long and the motor rotation time is also long. The motor rotates only for 45 seconds after the power is turned on, between 55 and 105 seconds, and between 115 and 120 seconds, for a total of 100 seconds.

[0069] The motor rotation and water supply stop 120 seconds after the power is turned on, but after 120 seconds, the water remaining in the siphon drain pipe is pulled and discharged by the siphon, and drainage ends 130 seconds after water supply begins.

[0070] (Example) Next, the operation of the disposer water supply system of the embodiment will be described with reference to the timing chart of FIG. 2 and the flow chart of FIG.

[0071] In the system of the embodiment, as in the system of the comparative example 2, the length of the horizontal pipe is, for example, 20 m. However, the timing of the operation of the motor is different from that of the system of the comparative example 2.

[0072] (1) In the disposer water supply system of the embodiment, when the power supply to the disposer 22 is turned on (step 100), as shown in Fig. 2, water supply to the hopper 50 is started first (step 102), and for 40 seconds, the motor 52 does not rotate and only the water supply is performed. Note that a certain amount of water is stored in the hopper, and the supplied water is discharged from the disposer 22 through the hopper 50. In this embodiment as well, some time after the water is supplied, the drainage water that has filled the horizontal pipe reaches the vertical pipe, and when the full drainage water falls inside the vertical pipe, a siphon force is generated, and the drainage water upstream of the vertical pipe is sucked into the vertical pipe, thereby enabling efficient drainage.

[0073] (2) When a preset time (first predetermined time T1; in this embodiment, for example, 40 seconds) has elapsed (step 104), the motor 52 rotates (step 106), the kitchen waste is crushed by the rotating crushing member 54, and the crushed kitchen waste is discharged from the disposer 22 together with the water in the hopper.

[0074] (3) When a preset time (65 seconds in this embodiment) has elapsed since the start of rotation of the motor 52, the motor 52 is stopped for a preset time (10 seconds) (steps 108, 110). Since the supply of water continues while the rotation of the motor 52 is stopped, a certain amount of the supplied water is stored in the hopper 50.

[0075] After a preset time has elapsed since the motor 52 stopped (in this embodiment, 10 seconds after the motor 52 stopped), the motor 52 restarts rotating (steps 112, 114). When the motor 52 restarts and the crushing member 54 starts rotating, the water in the hopper 50 is forcibly pushed into the siphon drain pipe, making it easier for the siphon to start again, and efficient drainage is achieved.

[0076] After the motor 52 rotates for a preset time (5 seconds in this embodiment), the rotation of the motor 52 and the water supply stop. That is, the rotation of the motor 52 and the water supply stop 120 seconds after the power is turned on, which is the second predetermined time T4 (steps 116, 118). Note that the rotation of the motor and the water supply stop 120 seconds after the power is turned on, but after 120 seconds, the water remaining in the siphon drain pipe is being pulled by the siphon and discharged. The stop here is an example of the stop process of the present disclosure.

[0077] Comparing Comparative Example 2 with the Example, in which the length of the horizontal pipe was 20 m, in Comparative Example 2, water supply and rotation of motor 52 start simultaneously, whereas in the Example, after water supply, rotation of motor 52 starts with a delay of a first predetermined time T1 (40 seconds). Therefore, in the Example, the rotation time of motor 52 was shortened compared to Comparative Example 2.

[0078] [Other embodiments] Although one embodiment of the present invention has been described above, the present invention is not limited to the above, and it goes without saying that the present invention can be implemented in various modified forms without departing from the spirit and scope of the present invention.

[0079] The water supply time, motor rotation time, first time, and second time described in the above embodiments are merely examples and may be changed as appropriate depending on the length of the siphon drain pipe, the specifications of the disposer, etc. [Explanation of symbols]
