Technical field

TECHNICAL FIELD [0001] The present invention relates to a disposer device, wherein a water supply opening / closing valve is provided on a water supply port side of the disposer device main body, and a drainage opening / closing valve is provided on a drain port side, and the drainage opening / closing valve is closed while the water supply opening / closing valve is closed. The present invention relates to a disposer device that opens the valve and cleans the drain pipe by draining the water stored in the disposer body into a drain pipe connected to the drain port. The present invention also relates to a cleaning / rinsing method for the disposer device. More specifically, the disposer device main body is provided with a water supply on / off valve on the water supply side, a drain on / off valve on the drain port side, and the water supply on / off valve is closed. The present invention relates to a disposer device that cleans the drain pipe by opening the drain on-off valve while draining and draining the water supply stored in the disposer apparatus main body to the drain pipe connected to the drain port.

Background art

[0002] In recent years, disposer devices have been widely used for crushing garbage such as garbage generated in ordinary households and restaurants and discharging it to sewage. As a crushing method for the disposer apparatus, a grinder type in which a crushing unit in which a plurality of crushing blades are stacked in a hopper of the disposer apparatus is detachably provided is widely used.

[0003] Since the crushing unit rotates at the time of crushing operation of the disposer device, the throwing port diameter of the disposer device is designed to be small (for example, 82 mm) so that the user does not touch the fracturing unit directly. For this reason, it was difficult to clean the residue remaining inside the hopper after the crushing process was completed. As a result, the residue remaining inside the hopper was not rotted or slime, etc., which caused a bad odor.

[0004] Therefore, in order to facilitate the cleaning of the inside of the hopper, a disposer apparatus has been developed in which the disposer apparatus is designed to have a large diameter (for example, 130 mm). In order to prevent the user from touching the crushing unit directly while increasing the inlet diameter, the hopper inlet is closed with a lid during the crushing operation of the device.

[0005] In this disposer device, in addition to the inner wall surface of the hopper, The crushed residue is likely to remain at the bottom plate that guides the crushed material to the discharge port or at the connection between the hopper and the discharge pipe. For this reason, even if the diameter of the inlet of the disposer device is increased, if the residue is completely eliminated, the problem will be solved.

[0006] In view of this, a disposer device is disclosed in which a crushing unit is configured to be detachable with a hopper force in order to remove residues such as the bottom plate of the disposer device as described above (Japanese Patent Laid-Open No. 2004-298809). ).

[0007] However, in the disposer apparatus disclosed in the above-mentioned Japanese Patent Application Laid-Open No. 2004-298809, when cleaning the inside of the hopper after the crushing process, the user himself takes out the demolition unit from the kitchen sink and removes the inside of the crushing unit and the hopper. There was a problem that it had to be cleaned, and it took time and effort. In addition, when the user himself / herself cleans, the connection part between the hopper and the discharge pipe is a difficult place to clean, so it was difficult to completely eliminate slime and odor. Furthermore, there was a problem that the crushed material and the cleaning agent remained inside the hopper just by performing the cleaning process after the crushing process.

[0008] Further, the soot introduced into the disposer device is crushed by a crushing unit such as a crushing blade and then drained into a drain pipe. At this time, in order to make the dredging easier to flow into the drainage pipe, a constant amount of water (crushed water) is always supplied during crushing treatment, and the crushed dredging water flows into the drainage pipe along with this crushing water.

However, a general disposer device leaves the above-described water supply operation to the user's judgment. For this reason, there may be cases where the necessary amount of water supply (for example, 8LZ) is not enough to supply water or the water supply is stopped during the drainage of crushed dredging. As a result, crushed soot remains in the drain pipe, which accumulates and accumulates in the drain pipe, causing clogging of the drain pipe.

[0010] Therefore, in order to ensure the necessary amount of water supply in the crushing mode, a so-called automatic water supply type disposer device has been developed that automatically starts water supply when the operation is switched to the crushing mode ( For example, refer to JP 2004-220783 A). In this disposer device, for example, a water supply port is provided on the side wall of the hopper, and a predetermined amount of water is automatically supplied into the hopper! /

[0011] The automatic water supply type disc disclosed in the above-mentioned Japanese Patent Application Laid-Open No. 2004-220783 is performed with a force. Even when the Poser device is used, there are the following problems. For example, in recent years, in housing complexes, multiple dwelling unit exclusive parts (infills) and the frame parts that support those dwelling unit exclusive parts

Skeleton infill houses (hereinafter referred to as SI houses) composed of (skeletons) are widely used. In the case of SI housing, a common vertical main is placed in a common area (eg corridor). Since this common drain pipe is separated from the drainage section of each room, for example, in the kitchen, there is a tendency for the length of the drainage side branch pipe to be connected between them to be long. The crushed soot tends to remain in the side branch pipe. For this reason, it is difficult to wash away all the soot in the drainage pipe side branch pipe. As a result, over time, soot accumulates and accumulates in the drainage pipe, which may cause a problem that the drainage pipe is clogged and a bad odor is caused.

[0012] The present invention has been made in view of the above problems, and an object thereof is to provide a cleaning Z rinsing method for a disposer apparatus that can easily keep the inside of the disposer apparatus clean. .

Another object of the present invention is to provide a disposer device that can easily clean the drain pipe and prevent clogging of the drain pipe.

Disclosure of the invention

Means for solving the problem

[0013] In order to solve the above-mentioned problem, the present invention provides a disposer device that crushes the culm thrown into the hopper with a crushing means, and discharges the crushed culm together with the water supplied by the water supply means together with the hopper force. A cleaning step of driving the crushing means and cleaning the inside of the disposer device using a cleaning liquid containing a cleaning agent in the water supplied from the water supply means, And a rinsing step of driving the crushing means and rinsing the inside of the disposer apparatus using the water supplied by the water supply means after the cleaning step.

In the present invention, the cleaning process of the disposer device is performed by supplying a cleaning liquid while driving the crushing means. Since the crushing means is driven to rotate, the supplied cleaning liquid is washed between the inner wall surface of the hopper, between the crushing blades of the crushing unit, and every corner on the back side to clean the inside of the hopper. The cleaning liquid used in the cleaning is also discharged from the hopper discharge loca. this The discharged cleaning liquid includes soot remaining from the crushing process.

[0015] In some cases, the cleaning agent or wrinkles during the crushing process may remain in the hopper after the cleaning process. Therefore, in the present invention, a rinsing step is further provided after the cleaning step. The rinsing step is performed by supplying water while driving the crushing means. Since the crushing means is driven to rotate, the supplied water reaches the corners on the inner wall of the hopper, between the crushing blades of the crushing unit and on the back side (hereinafter referred to as the inside of the hopper), and remains in these parts. Wash away any cleaning solution. The water used for rinsing is also discharged from the hopper discharge loca. This discharged water includes cleaning liquid and soot remaining slightly from the time of crushing.

[0016] In the present invention, the cleaning agent refers to a general neutral detergent, an enzyme that decomposes oil, a substance that removes slime, a function such as sterilization, disinfection, fragrance, mold prevention, or suppression of generation of microorganisms. Means having

[0017] Further, the inside of the disposer device includes the inside of the hopper, the bottom plate surface provided below the hopper, and the discharge port through which crushed material and cleaning liquid are discharged.

[0018] Further, in the cleaning Z rinsing method of the disposer apparatus according to the present invention, the disposer apparatus includes an opening / closing valve provided on the discharge port side of the hopper, and the opening / closing valve is closed in the rinsing step after the opening / closing valve is closed. It is also preferable that water is supplied into the hopper by water supply means, and the inside of the disposer device is rinsed in a state where a predetermined amount of water is accumulated in the hopper.

[0019] According to this method, since the rinsing process is performed in a state where a predetermined amount of water is accumulated in the hopper, the entire inner surface of the hopper touches the accumulated water, and the entire hopper can be reliably rinsed. . In addition, water can be saved in the case of stored water. Furthermore, after the rinsing process, the accumulated water is discharged at once, so that the soot remaining at the outlet can be surely poured.

[0020] Here, the discharged material includes, in addition to the residue of the waste, the cleaning liquid used in the cleaning process, the water used in the rinsing process, and the like.

[0021] Further, in the case of the rinsing step in which water is stored as described above, it is preferable to start the rinsing step after the cleaning liquid inside the hopper is completely discharged in the cleaning step.

[0022] According to this method, the cleaning liquid remaining after the crushing process can be avoided from being used as rinsing water in the rinsing process. [0023] Further, in the cleaning Z rinsing method of the disposer apparatus of the present invention, the disposer apparatus has a cleaning agent supply means for supplying the cleaning agent into the hopper, and the cleaning agent supply means is the disposer apparatus. It is also preferable to supply the cleaning agent into the hopper when the operation is switched to the cleaning step.

[0024] It is also preferable to perform the washing step and the rinsing step after the crushing treatment is performed a plurality of times.

[0025] According to this method, since the cleaning Z rinsing process is automatically started without the user's awareness, the disposer device can always be kept clean.

[0026] In order to solve the above problems, the present invention provides a disposer device main body provided with a water supply port on its upper side and a drain port for draining crushed dredging on its lower side, A water supply opening / closing valve provided on the water supply port side of the disposer device main body, a drainage opening / closing valve provided on the drain port side of the disposer device main body, the water supply opening / closing valve, and the drainage opening / closing valve; A control unit for controlling the opening / closing operation of the water, and the control unit opens the drainage on / off valve while closing the water supply on / off valve for a certain amount of water stored in the disposer device main body. Thus, the drain pipe is drained to the drain pipe communicated with the drain port, and the drain pipe is washed. In the following, the drain pipe cleaning process is referred to as “flushing” without accompanying such a crushing process.

[0027] When the drainage on-off valve is closed and the water supply on-off valve is opened by the control unit, water is supplied to the inside of the disposer device main body. Since the drainage on-off valve is closed, a certain amount of water is stored inside the device. When a certain amount of water is collected, the water supply on / off valve is closed and the drain on / off valve is opened, and a certain amount of water stored inside the disposer device main body enters the drain pipe through the drain port. Drained. In the present invention, since a certain amount of water is stored and drained, the drain pipe is discharged at a fixed time per time compared to the crushing mode in which crushing is performed while the water supply is sequentially drained with the on-off valve open. The amount of water drained into the water increases. As a result, the collected water flows into the drain pipe at once, so that the water accumulated in the drain pipe by this water flow is drained into the crushing tank.

[0028] Further, in the disposer device according to the present invention, the disposer device body includes the drain pipe. An operation unit for inputting a set value based on information for shifting to an operation for performing a cleaning process, and the control unit counts a value corresponding to the information, and adds the information input from the operation unit to the information. The set value based on this is compared with the counted value, and based on the result of the comparison, the operation is shifted to the operation of performing the washing treatment of the drain pipe.

[0029] Further, as the information for shifting to the operation of performing the drain pipe cleaning process, the number of times, hours, or days in which the crushing mode for crushing the soot is selected is used.

[0030] According to this configuration, the operation of the disposer device is automatically shifted to drain pipe cleaning based on information input by the operation unit. Therefore, the automatic transition process eliminates the need for the user to sequentially switch the operation of cleaning the drain pipe, thereby reducing the burden on the user.

[0031] Further, the disposer device of the present invention has mode selection means for switching the disposer device main body between a crushing mode for crushing the ridge and a drain pipe cleaning mode for performing the drain pipe cleaning process, When the mode selection means switches to the drain pipe cleaning mode, the control unit shifts to an operation for performing the drain pipe cleaning process.

[0032] According to this configuration, when the user selects each operation of the mode selection unit, the operation of the disposer device is switched to each mode. Therefore, the operation of the disposer device can be automatically shifted to drain pipe cleaning regardless of the user's intention.

The invention's effect

[0033] According to the present invention, since the rinsing process is further provided after the cleaning process, the cleaning agent remaining after the cleaning process, the residue remaining in the crushing process, etc. can be reliably discharged from the disposer device. Can do. Thereby, the inside of a hopper can be kept cleaner. According to the present invention, since the water stored in the disposer device main body is caused to flow to the drain pipe at once, the drain pipe is washed with the collected drainage, and the effect of suppressing the clogging of the drain pipe is obtained.

In addition, the connecting pipe 66 is provided with a tap water open / close valve (for example, a solenoid valve) 55, and the water supply open / close valve 55 is opened and closed in conjunction with the operation mode of the disposer device 1, so that The supply of tap water is controlled.

[0039] Inside the hopper 3, a crushing unit 6 is detachably attached to the hopper 3. The crushing unit 6 includes a crushing blade and a fixed crushing blade to constitute the crushing unit 6, and the rotating crushing blade is fitted to the drive shaft 7 a of the speed reduction unit 7. The configuration of the crushing unit 6 will be described later.

[0040] The upper portion of the hopper 3 is provided with a charging opening 4 for charging garbage such as garbage, and the charging opening 4 is closed by a lid 5. The lid 5 has a disk shape having substantially the same diameter as the input opening 4 and is detachably attached to the hopper 3. Also this lid 5 functions as a switch for switching the operation mode of the disposer device.

FIG. 2 shows a top view of the lid body 5 attached to the flange 74. As shown in FIG. 2, the word “OFF” is written on the flange 74 arranged around the lid 5, and it is rotated clockwise by 60 ° in the illustrated state from this “OFF” position. The text “Fracture mode” is displayed at the position. On the other hand, the characters “wash Z rinsing mode” are written at the position rotated 60 ° counterclockwise in the illustrated state from the position marked “OFF”. Corresponding to the position where each mode of the flange 74 is indicated, the lid 5 is provided with, for example, a magnet, and a proximity sensor is provided at the position of the hopper 3 facing this. When the lid 5 is rotated to each mode position, the operation mode of the disposer device 1 is switched to each mode described above.

[0042] Further, the lid body 5 is provided with an attaching / detaching mechanism that performs a rotation operation to lock and unlock the lid body 5 in a closed state. For example, the lid 5 is attached to the inside of the opening 4 corresponding to the hopper 3 and is rotated from the “OFF” notation position to the “crushing mode” notation position, or from the “OF Fj notation position” to the “wash Z When it is rotated to the notation position “rinsing mode”, a rib or the like (not shown) of the lid 5 is locked and the lid 5 is locked to the closing opening 4 in a closed state. In addition, the lid 5 in the locked state can be rotated from the notation position of “crushing mode” to the notation position of “OFF” or from the notation position of “wash Z rinsing mode” to the notation position of “OFF”. When it is rotated, the locking of the ribs and the like is released and the lock is released, and the lid 5 is detachable to the inside corresponding to the hopper 3 of the closing opening 4.

Returning to FIG. 1, a bottom plate 10 inclined toward the drain pipe connection port 8 formed on the outer periphery of the hopper 3 is provided at the lower part of the hopper 3, and the drive of the speed reduction unit 7 is provided at the center of the bottom plate 10. A shaft hole portion through which the shaft 7a passes is formed.

A drive motor 82 for driving the crushing unit 6 is installed on the outer periphery of the hopper. A rotation shaft (not shown) of the drive motor 82 is connected to the drive shaft 7 a of the speed reduction unit 7, and the rotation crushing blade of the crushing unit 6 is rotated by the drive of the drive motor 82.

[0045] A cleaning agent storage tank 62 for storing the cleaning agent is provided on the outer peripheral upper portion of the hopper 3 on the back side of the kitchen sink S via the mounting table 63. This cleaning agent storage tank 62 is an example of cleaning agent supply means. The cleaning agent storage tank 62 has a predetermined amount of cleaning. The agent is contained. Suitable detergents include, for example, general neutral detergents, enzymes that degrade oils, those that remove slime, and those that have functions such as sterilization, disinfection, aroma, mildew prevention, and generation control of microorganisms. Used for. Further, the cleaning agent may be any of solid, gel or liquid type. Then, it is preferable that the cleaning agent storage tank 62 has a size that can store an amount of cleaning agent that will not disappear for more than 3 months to half a year, assuming that the cleaning process is performed once for Z1 weeks. It is also preferable to attach a fuel gauge to the cleaning agent storage tank 62 so that the amount of cleaning agent can be checked appropriately.

A cleaning agent injection pipe 64 that connects the cleaning agent storage tank 62 and the disposer device 1 is attached to the lower side surface of the cleaning agent storage tank 62. This cleaning agent injection pipe 64 is an example of a cleaning agent supply means. The cleaning agent injection pipe 64 is provided with a cleaning agent opening / closing valve (for example, a solenoid valve) 60 for controlling the injection amount of the cleaning agent, and the cleaning agent opening / closing valve 60 in conjunction with the switching of the operation mode of the disposer device 1. Is opened and closed. When the cleaning agent on-off valve 60 is opened, the cleaning agent is injected into the hopper 3 by the weight of the cleaning agent. The cleaning agent storage tank 62 is installed at a position where the cleaning agent injection pipe 64 is higher than the surface of the cleaning liquid stored in the hopper 3. As a result, the backflow of the cleaning liquid stored in the hopper 3 to the cleaning agent storage tank 62 is prevented.

It should be noted that the cleaning agent storage tank 62 may be installed detachably with respect to the kitchen sink S and the disposer device 1 or may be configured integrally with the disposer device 1. In the case of detachable installation, a space for accommodating the cleaning agent storage tank 62 may be provided in the kitchen sink S, and the cleaning agent storage tank 62 may be detachably stored in this space. Thereby, the cleaning agent storage tank 62 can be easily taken out, and the cleaning agent can be easily replenished. Further, the cleaning agent storage tank 62 itself may be replaced. In the example shown in FIG. 1, the cleaning agent storage tank 62 is installed via the mounting table 63 above the protruding portion 3b protruding so as to cover the drive motor 82 of the hopper 3, but the cleaning agent storage tank The position where 62 is installed is not limited to this! /.

[0048] Furthermore, the method for injecting the cleaning agent from the cleaning agent storage tank 62 into the hopper 3 is to provide the cleaning agent storage tank 62 with a pump and drive the pump to inject the cleaning agent into the hopper 3. You may do it. [0049] Below the hopper 3, a discharge treatment tank (not shown) in which discharged substances are stored is installed. The discharge treatment tank and the drain pipe connection port 8 formed at the lower end of the peripheral surface of the hopper 3 are communicated with each other via an S-shaped drain pipe 50 (generally referred to as an S-shaped trap). In addition, a drain opening / closing valve (for example, a solenoid valve) 52 for controlling drainage inside the hopper 3 is provided in the vicinity of the downstream side of the drainage pipe connection port 8, and interlocks with switching of the operation mode of the disposer device 1. Open and close. When the drainage on-off valve 52 is opened, the crushed garbage, the crushed water used at the time of crushing, the cleaning liquid used at the time of washing Z rinse, etc. are discharged to the discharge treatment tank from the drain pipe connection port 8 of the hopper 3 .

Next, the configuration of the crushing unit 6 will be described with reference to FIG. 1 and FIGS. 3A to 7B.

[0051] As shown in FIG. 1, the crushing unit 6 includes a plurality of crushing blades, and in this example, 5 crushing blades are stacked. That is, 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 are stacked in this order to constitute the crushing unit 6. The By holding the crushing unit 6 on the inner surface of the hopper 3, a rupture chamber is formed.

[0052] 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 are overlapped with almost no vertical spacing. The dimensions are set so that the crushed garbage does not enter the crevice between the upper and lower edges of the crushing blade and remain in the crushing unit 6.

FIG. 3A is a plan view showing a configuration of the first rotary crushing blade 12 arranged at the uppermost stage of the crushing unit 6, FIG. 3B is a front view, and FIG. 3C is a right side view of FIG. 3B. The first rotary crushing blade 12 includes a single stirring arm 20 in which the side force of the bearing portion 19 extends horizontally. The first rotary crushing blades 12 are formed with pushing surfaces 20 a on both front and rear surfaces in the rotation direction of the stirring arm 20.

The pushing surface 20a 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 stirring arm 20, the first rotary crushing blade 12 moves downward with respect to the garbage that is in contact with the pushing surface 20a in both forward and reverse rotations. The force to be pressed against can be controlled. As a result, the first rotary crushing blade 12 takes in the garbage by rotation and moves it to the lower crushing blade. Push in.

[0055] The first rotary crushing blade 12 has an edge 20b formed on the lower end side of both side surfaces of the pushing surface 20a, and coarsely crushes garbage in cooperation with the first fixed crushing blade 13 shown in Figs. 4A to 4C. It functions as a crushing blade.

The first rotary crushing blade 12 has a handle 21 formed on the upper surface of the stirring arm 20. The handle 21 is provided at a position 90 ° away from the stirring arm 20 so as to extend from the bearing 19 to the left and right by the same length. The handle 21 functions as a grip (handle) when pulling up the crushing unit 6.

[0057] In order to be used as a gripping portion, the handle 21 is selected to have a length that allows a finger to be applied. The bearing portion 19 has a through hole 19a through which a shaft head (locking portion) of a rotary drive shaft 36 (see FIG. 1) provided on a third rotary crushing blade 16 described later can be inserted. . The through-hole 19a has a substantially D-shape when viewed from above. Therefore, the corresponding portion of the rotary drive shaft 36 also has a substantially D-shape when viewed from above, so that both can rotate integrally. Made.

FIG. 4A is a plan view showing a configuration of the first fixed crushing blade 13 arranged at the lower stage of the first rotary crushing blade 12, 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 at the upper and lower ends of both side surfaces. In cooperation with the first rotary crushing blade 12 and the second rotary crushing blade 14 shown in FIGS. 5A and 5C described above. Functions as a crushing blade.

[0059] Each arm 23 is provided with a tab 24 that functions as 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 first fixed crushing is achieved by fitting the tab 24 into the fitting groove 3a (see FIG. 1) of the hopper 3. The rotation of the blade 13 is restricted. In this example, a long tab whose entire length is selected in consideration of the mounting position (depth) of the first rotary crushing blade 12 with respect to the hopper 3 is used.

[0060] The reason why the long tab 24 is used is to ensure that the rotation of the first fixed crushing blade 13 is restricted. The second reason is to fill the fitting groove 3a with the tab 24 while minimizing the space of the fitting groove 3a. Therefore, 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 increased. [0061] Further, when the crushing unit 6 is attached to the hopper 3 as shown in Fig. 1 by lengthening the upper tab 24a in this way, the opening opening 4 side force also has less space to the tip of the upper tab 24a. Thus, the broken garbage is prevented from adhering to the fitting 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 attached to the fitting groove 3a and to more smoothly engage the tab 24 to the fitting groove 3a.

[0063] When the second rotary crushing blade 14 is interposed between the first fixed crushing blade 13 and the second fixed crushing blade 15, the lower tab 24b is formed with a gap having a predetermined height. It is provided to do this. Therefore, in this example, the length of the lower tab 24b is selected to be approximately 1Z2 up to the cutting edge of the second rotary crushing blade 14!

[0064] The diameter of the inner hole 23a of the hub 22 is such that the shaft diameter of the second rotary crushing blade 14 shown in Figs. 5A and 5B is larger than the diameter of the rotary drive shaft 36. Do not interfere with the rotary drive shaft 36! / Speak.

FIG. 5A is a plan view showing the configuration of the second rotary crushing blade 14 arranged at the lower stage of the first fixed crushing blade 13, and FIG. 5B is a cross-sectional view along the line AA.

[0066] The second rotary crushing blade 14 includes three arms 28 extending 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.

[0067] The central portion of the hub 27 of the second rotary crushing blade 14 is provided with an engagement hole 27a, which is engaged with the rotary drive shaft 36 (see Fig. 1), whereby rotational force is generated by the second rotary crushing blade. Given to 14. Therefore, the engagement hole 27a that contacts the second rotary crushing blade 14 in the same manner as 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 upper force is the same as described above, but it may be a D-shaped shape.

FIG. 6A is a plan view showing a configuration example of the second fixed crushing blade 15 disposed at the lower stage of the second rotary crushing blade 14 so as to be mated with the second rotary crushing blade 14, and FIG. 6B It is a BB cross-sectional view. [0069] 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 33a are formed on the outer periphery of the ring 33 at intervals of 180 °. The pair of tabs 33a 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 into 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 24b of the first fixed crushing blade 13. The rotation of the second fixed crushing blade 15 is restricted by fitting the tab 33a into the fitting groove 3a.

[0070] These tabs 33a have a predetermined height, and the lower tab 24b of the first fixed crushing blade 13 contacts the upper surface of the tab 33a, so that the first fixed crushing blade 13 and the second fixed crushing blade 13 are in contact with each other. A clearance of a predetermined height is formed between the blade 15 and the dimensions so as to fit exactly with the second rotary crushing blade 14. The center hole 30a of the hub 30 is dimensioned so as not to interfere with the rotary drive shaft.

[0071] The second fixed crushing blade 15 has eight arms 31, and the six arms 31 have comb teeth 3la formed on the upper surface. The comb teeth 31a of the second fixed crushing blade 15 has a pitch that allows the comb teeth 28a of the second rotary crushing blade 14 shown in FIGS. 5A and 5B to pass between the teeth, as shown in FIG. Further, when the second rotary crushing blade 14 and the second fixed crushing blade 15 are overlapped with each other, a narrow gap is formed between the comb tooth portions 28a and 31a.

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.

[0073] As described above, the arm 28 of the second rotary crushing blade 14 has three arms 28 and the arm 31 of the second fixed crushing blade 15 has eight arms. The interval of is narrow.

[0074] Therefore, when the comb teeth 31a are provided on all eight arms 31, the comb teeth 31a of the second fixed crushing blade 15 always exist between the arms 28 of the second rotary crushing blade 14. When a certain amount of block-shaped garbage is put into the state, it is assumed that the garbage will not enter between the arms 28 of the second rotary crushing blade 14 and become difficult to crush.

[0075] 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 31a, so that the second rotary crushing blade 14 is rotating. If the arm 31 is located between the arms 28 of the second rotary crushing blade 14 by providing the comb tooth portion 3 la of the second fixed crushing blade 15, a wide space is formed in the circumferential direction! To be. [0076] Thereby, even when a certain amount of block-shaped garbage is thrown in, the garbage enters between the arms 28 of the second rotary crushing blade 14, and the second rotary crushing blade 14 is rotated by the rotational motion to comb. The garbage is broken by the cooperation of the tooth portion 28a and the comb tooth portion 31a of the other arm 31 of the second fixed crushing blade 15.

[0077] Note that, when the number of the arms 31 in the second fixed crushing blade 15 where the comb teeth 31a are not provided is large, the crushing ability is lowered. For example, when the eight arms 31 are provided, the comb teeth 31a are not provided. Do not set up! As shown in the figure, two arms 32 are preferred! /.

[0078] Each arm 32 extends radially along the tangential direction of the hub 30, so that when the second rotary crushing blade 14 rotates, the crushing point with the second fixed crushing blade 15 is set in the circumferential direction. By shifting, the peak of the crushing load is suppressed and the load is flat.

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

FIG. 7A is a plan view showing a configuration example of the third rotary crushing blade 16, and FIG. 7B is a side view thereof.

[0081] 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.

[0082] 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 FIGS. 6A and 6B. Further, the slit 35a shown in FIGS. 7A and 7B penetrates through the third rotary crushing blade 16, and a sharp edge is formed at the opening edge of the upper surface side of the slit 35a.

[0083] The top 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 the bottom surface of one side of the arms 31 and 32 of the second fixed crushing blade 15 is on the bottom surface. Since the wave fronts 31b and 32a that are inclined to the side are formed, the third rotary crushing blade 16 rotates with respect to the garbage (that has been crushed to a certain size) in contact with the wave fronts 31b and 32a. Thus, the pressing force can be applied to the third rotary crushing blade 16.

[0084] The third rotary crushing blade is crushed by the comb tooth portion 28a (Figs. 5A and 5B) of the second rotary crushing blade 14 and the comb tooth portion 31a (Figs. 6A and 6B) of the second fixed crushing blade 15. Garbage that has fallen on the upper surface of 16 is caught in the slit 35a. However, when the third rotary crushing blade 16 rotates, it is pressed against the garbage force S slit 35a by the wave fronts 31b and 32a. This rotation operation destroys garbage by the edge of slit 35a. Then, the garbage that has been crushed is dropped through the slit 35a, passes through the bottom plate 10 of the hopper 3 shown in FIG. 1, and is discharged from the drain pipe connection port 8 to the outside.

Note that the slit 35a is formed with an opening (or an opening step) that widens by force toward the bottom surface side, so that the garbage pushed into the slit 35a can easily fall.

A rotational 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 has 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 others are round shafts. The shaft head is then threaded so that it functions as a locking part 36a! RU

[0087] A fitting portion 37 that functions as a part of the rotational 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 7a of the reduction unit 7 described above. RU In order for the fitting portion 37 to be in a good fitting state with the drive shaft 7a, the inner hole 37a (see FIG. 1) is a square hole. Hexagonal holes may be used. In addition, it is assumed that the fitting length of the fitting portion 37 is selected so that the fitting portion 37 can be fitted to the drive shaft 7a of the speed reduction unit 7 as much as possible.

[0088] 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 as described above are arranged in this order, The rotary drive shafts 36 provided in the third rotary crushing blade 16 are passed through each other so as to be stacked. After that, as shown in FIG. 1, a plurality of crushing blades 12 to 16 are assembled by tightening screws 29a from the upper ends of the locking portions 36a, which are the heads of the rotary drive shafts 36, and tightening them. Obtained crushing unit 6 is obtained. The At this time, the tabs 24 of the first fixed crushing blade 13 and the tabs 33a of the second fixed crushing blade 15 are integrated with their positional relationships adjusted so as to be continuous (in a straight line).

[0089] Then, with the tabs 24 and 33a fitted in the fitting groove 3a, the crushing unit 6 is lowered in the hopper 3 along the fitting groove 3a. At this time, the breaking unit 6 is lowered using the gripping part 21. When the crushing unit 6 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 7a of the speed reduction unit 7 shown in FIG.

Here, the tabs 24 and 33a of the crushing unit 6 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. By using the long tab 24 and the relatively short tab 33a, the crushing unit 6 can be stably locked to the hopper 3. Thus, by extending the tab 24 relatively long, the crushing unit 6 can be reliably fixed in the hopper 3 while preventing the crushing unit 6 from rotating. Since the crushing unit 6 is simply fitted to the hopper 3, the crushing unit 6 can be easily pulled up. Therefore, the hopper 3 and the crushing unit 6 can be easily cleaned.

[0091] The crushing unit 6 may have a structure in which a force housing having a structure directly fixed to the hopper 3 is prepared, and the crushing unit is fixed to the housing.

[0092] Since the crushing unit 6 is fitted to the drive shaft 7a by its own weight, the rotary drive shaft 36 may not come off from the drive shaft 7a during operation of the apparatus!

Next, control of the disposer device 1 will be described with reference to FIG. FIG. 8 is a block diagram showing the configuration of the disposer device 1.

The disposer device 1 has a control unit 78 that controls the operation of the entire disposer device. The control unit 78 has a CPU (Central Processing Unit), a ROM (Read Only Memory) in which the CPU operation program is stored, a RAM (Random Access Memory) that constitutes the work area of the CPU, and the like. The

The lid 5 has a switch function for switching the operation mode of the disposer device.

When the lid 5 is switched to the “crushing mode”, the crushing mode signal S1 is generated, and when the lid 5 is switched to the “washing Z rinsing mode”, the cleaning Z rinsing mode signal S2 is generated. The generated signals S 1 and S2 are supplied to the control unit 78. The drain on / off valve 52 of the drain pipe 50 is connected to the control unit 78. When the cleaning Z rinsing mode signal S2 is supplied, the control unit 78 generates a drain pipe opening / closing signal S2a corresponding to the drain opening / closing valve 52. Then, the generated drain pipe opening / closing signal S2a is supplied to the drain on / off valve 52 of the drain pipe 50, and the opening / closing operation of the drain on / off valve 52 of the drain pipe 50 is controlled.

The water supply on / off valve 55 of the connecting pipe 66 is connected to the control unit 78. When the cleaning Z rinsing mode signal S2 is supplied, the control unit 78 generates a connection pipe opening / closing signal S2b corresponding to the water supply opening / closing valve 55. Then, the generated connection pipe opening / closing signal S2b is supplied to the water supply opening / closing valve 55 of the connection pipe 66, and the opening / closing operation of the water supply opening / closing valve 55 is controlled.

The cleaning agent on / off valve 60 of the cleaning agent storage tank 62 is connected to the control unit 78. When the cleaning Z rinsing mode signal S2 is supplied, the control unit 78 generates an injection pipe opening / closing signal S2c corresponding to the cleaning agent opening / closing valve 60. Then, the generated injection pipe opening / closing signal S2c is supplied to the cleaning agent on / off valve 60 of the cleaning agent injection pipe 64, and the opening / closing of the cleaning agent on / off valve 60 of the cleaning agent storage tank 62 is controlled.

A drive motor 82 for driving the crushing unit 6 is connected to the control unit 78. When the crushing mode signal S1 or the cleaning Z rinsing mode signal S2 is supplied from the lid 5, the control unit 78 generates drive (stop) signals Sid, S2d corresponding to the respective mode signals, and drives the drive motor. Supply to 82. The drive motor 82 is driven by the supplied drive signals Sid and S2d, and rotates the crushing unit 6 in conjunction with this.

[0100] The speaker 80 is connected to the control unit 78, and when the drive signals Sid and S2d are supplied to the drive motor 82 that rotationally drives the crushing unit 6, a certain period of time has passed and the control unit 78 is connected to the speaker 80. Supply Sle and S2e. Until the speaker 80, the end signal Sle, S2e is generated to generate a buzzer sound to inform the user of the end of the crushing or cleaning Z rinsing process.

Next, the operation of the disposer device 1 will be described. FIG. 9 is a flowchart showing the operation mode switching operation of the disposer device 1. In the following description, since a known method is adopted for the “crushing mode”, the description is omitted.

[0102] First, in step S10, the user selects an operation mode of the disposer device 1. The operation mode is selected by changing the lid 5 from “OFF” to “Fracture mode” or from “OFF” to “Washing”. This is done by rotating it to the “cleaning mode” position. Here, when “crushing mode” is selected, the process proceeds to step S40, and when “cleaning Z rinsing mode” is selected, the process proceeds to step S20. To change the operation mode, an operation unit (remote control device) with buttons for “crushing mode”, “washing / rinsing mode” and “OFF” is provided on a part of the kitchen sink S or the wall of the kitchen. Alternatively, this operation may be performed by selecting any button on the operation unit.

[0103] In step S40, a crushing process is performed, and in step S20, a washing Z rinsing process is performed. Details of each process will be described later. When the processing in steps 20 and 40 is completed, a buzzer sounds to notify the end of the processing. Based on the buzzer sound, the user returns the lid 5 from the “crushing mode” to the “OFF” position when the “breaking frame mode” is selected. On the other hand, when the “cleaning Z rinsing mode” is selected, the lid 5 is returned from the “cleaning Z rinsing mode” to the “OFF” position. That is, the lid 5 is returned to the initial position (step S60).

[0104] Generally, after the processing in the "crushing mode" is completed, the "washing Z rinsing mode" is selected to wash the crushed material remaining after the crushing processing. Therefore, when “crushing mode” is selected in step S10, “wash Z rinsing mode” may be selected in step S60.

Next, the operation of the disposer device 1 when “cleaning Z rinsing mode” is selected in step S10 shown in FIG. 9 will be described with reference to FIG. 1, FIG. 8, and FIG. FIG. 10 is a flowchart showing the operation of the cleaning Z rinsing mode.

First, when the operation mode of the disposer device 1 is switched to the “washing / rinsing mode” by the user, the control unit 78 supplies the drainage pipe closing signal to the drainage on-off valve 52 of the drainage pipe 50 in step S22. Close the drain valve 52.

Next, in step S 24, the controller 78 supplies a connection pipe open signal to the water supply on / off valve 55 of the connection pipe 66 and opens the water supply on / off valve 55 of the connection pipe 66. As a result, automatic water supply from the water pipe into the hopper 3 is started.

Next, the control unit 78 has a timer (counter) function, and determines whether or not a preset water supply time has passed with reference to when the water supply opening / closing valve 55 is opened ( Step S

26). If the set water supply time has elapsed, the water supply opening / closing valve is set in step S28. Close 55 and stop water supply to hopper 3. On the other hand, if the set water supply time has not elapsed, the water supply is continued with the open / close valve of the water pipe open (step S26). As a result, the on-off valve 52 for drainage of the drain pipe 50 is closed (step S22), so that a predetermined amount of tap water accumulates inside the hopper 3. Here, the “water supply time” is set to a time during which the supplied tap water does not overflow from the hopper 3, and the surface of the supplied tap water is the tip of the cleaning agent injection pipe 64 of the cleaning agent storage tank 62. The position is set so that it does not touch. Further, in this embodiment, a force that sets the amount of water stored in the hopper 3 according to time, for example, a sensor is provided on the inner peripheral surface of the hopper 3, and the tap water is stored in the hopper 3 until this sensor detects tap water. You can adopt the method! ,.

[0109] In parallel with step S24, when the drainage on-off valve 52 is closed, the control unit 78 supplies the injection pipe open signal to the cleaning agent on-off valve 60 in step S30 and performs cleaning. Open the cleaning agent on-off valve 60 of the agent injection pipe 64. As a result, the cleaning agent is automatically injected into the hopper 3. Next, in step S32, the control unit 78 determines whether or not the preset injection time has passed with reference to the time when the cleaning on-off valve 60 of the cleaning agent injection pipe 64 is opened. When the set injection time has elapsed, in step S34, the cleaning agent on / off valve 60 of the cleaning agent injection pipe 64 is closed to stop the injection of the cleaning agent into the hopper 3. On the other hand, if the set injection time has passed! / ヽ!, If the cleaning agent on-off valve 60 of the cleaning agent injection pipe 64 remains open, the cleaning agent injection is continued (step S32). ). As a result, the cleaning agent is mixed into the tap water in the hopper 3 so that the inside of the hopper 3 is filled with the cleaning liquid.

[0110] It should be noted that the timing of injecting the cleaning agent into the hopper 3 may be any time before the water supply is started, until the water supply is started and ended, or after the water supply is ended.

[0111] Next, in step S36, the control unit 78 supplies a drive signal to the drive motor 82 when the supply of tap water and the injection of the cleaning agent are stopped. The drive motor 82 is driven by this drive signal, and the crushing unit 6 is rotationally driven in conjunction with this. The crushing unit 6 is driven reversely every 5 seconds, for example. As a result, the cleaning liquid inside the hopper 3 is stirred by the crushing unit 6 and the cleaning process inside the hopper 3 is performed. Further, by rotating the crushing unit 6, the cleaning agent can be sufficiently mixed and dissolved in the tap water. [0112] The cleaning treatment may be performed at the start or during the supply of the power tap water and the cleaning agent performed after the cleaning liquid is accumulated in the hopper 3.

[0113] Next, in step S38, the controller 78 determines whether or not the cleaning process has passed a preset cleaning time. The cleaning time is set to 60 seconds, for example, by a timer. If the set cleaning time has elapsed, the process proceeds to step S41. If the set cleaning time has elapsed, in that case, the process returns to step S38.

Next, in step S 41, the controller 78 supplies the drain pipe open signal to the drain on / off valve 52 of the drain pipe 50. As a result, the drain opening / closing valve 52 of the drain pipe 50 is opened, and the cleaning liquid inside the hopper 3 and the crushed material remaining after the crushing process are drained into the discharge treatment tank through the drain pipe connection port 8. Furthermore, the crushed material remaining at the bottom plate 10 and the drain pipe connection port 8 is discharged at the same time. When drainage is started, the process proceeds to the rinsing process in step S48.

[0115] Next, in step S48, when drainage of the cleaning liquid accumulated in the hopper 3 is started, the control unit 78 supplies a connection pipe open signal to the water supply on / off valve 55 of the connection pipe 66, and the connection Open the water supply on / off valve 55 of the pipe 66. As a result, automatic water supply from the water pipe into the hopper 3 is started.

In parallel with step S48, in step S50, the control unit 78 supplies a drive signal to the drive motor 82 to drive the crushing unit 6 to rotate. At this time, the crushing unit 6 is driven reversely every 5 seconds, for example. As a result, the water supplied to the inside of the hopper 3 is scattered by the crushing unit 6 on the inner peripheral surface of the hopper 3 and spreads between the crushing blades and every corner on the back side of the crushing blades. Since the drainage on-off valve 52 is open (step S41), the supplied water passes through the crushing unit 6, the bottom plate 10, and the drainage pipe connection port 8 inside the hopper 3 into the discharge treatment tank. Discharged. At this time, the cleaning liquid in the cleaning process inside the hopper 3 and the crushed material in the crushing process and the crushed material remaining in the bottom plate 10 and the drain pipe connection port ⁸ are discharged at the same time.

[0117] Next, in step S52, the control unit 78 determines whether or not the rinsing process has passed a preset rinsing time. The rinsing time is set to a time that can sufficiently drain the cleaning solution remaining after the cleaning process. For example, if the tap water supplied is 8 liters Z minutes, it is set to 60 seconds, for example. If the set rinsing time has elapsed, step S54, 5 Shifting to 6, the supply water on-off valve 55 of the connecting pipe 66 is closed to stop the supply of tap water, and the crushing unit 6 is stopped. On the other hand, if the set rinsing time has not elapsed, the supply of tap water and the rotation of the crushing unit 6 are continued (step S52).

Next, in step S54, the control unit 78 supplies a connection pipe closing signal to the water supply on / off valve 55 of the connection pipe 66, and closes the water supply on / off valve 55 of the connection pipe 66. As a result, automatic water supply from the water pipe into the hopper 3 is stopped.

[0119] In parallel with step S54, in step S56, the controller 78 supplies a drive stop signal to the drive motor 82 to stop the crushing unit 6 from rotating.

[0120] In step S58, after stopping the supply of tap water and the driving of the crushing unit 6, a buzzer sound is generated to inform the user of the end of the rinsing process. A water detection sensor for detecting water may be provided on the bottom surface of the hopper 3 and a buzzer sound may be generated when the rinsing process is finished when the water detection sensor no longer detects water.

[0121] Here, the rinsing process has been performed through step S41 which is the same as or during the start of the drainage of the cleaning liquid. Instead, it is detected that the drainage of the cleaning liquid during the cleaning process is completed. It may be performed after step S44 described later.

FIG. 11 is a flowchart showing the operation of the disposer apparatus when the rinsing step is performed after the cleaning liquid drainage is completed. The processing from step S20 to step S41 is the same as the operation of the disposer apparatus shown in FIG.

[0123] First, in step S44, the controller 78 determines whether or not the drainage of the hopper 3 has been completed. Whether or not drainage inside the hopper 3 is completed is determined by installing a water detection sensor below or on the bottom of the inner peripheral surface of the hopper 3 and when the signal detected by the water detection sensor is turned off. Detects termination. Another method is to calculate the time of water drained from the hopper 3 from the amount of drainage drained from the drain pipe connection port 8 in advance, and that the drainage is completed when this calculated time has elapsed. It is also possible to judge.

[0124] When it is determined that the drainage of the cleaning liquid has been completed, the controller 78 performs a rinsing process in steps S48 to S58. Since the rinsing process is performed by the same method as the rinsing process described above, the description thereof is omitted.

[0125] According to this embodiment, the hopper 3 of the disposer device 1 is removed from the kitchen sink S. The disposer device 1 can be cleaned and rinsed in the kitchen sink s without removing it.

[0126] In addition, when only the cleaning process is provided after the crushing process, the cleaning liquid used in the cleaning process and wrinkles during the crushing process may remain. On the other hand, according to this embodiment, since the rinsing process is further provided after the cleaning process, the remaining cleaning agent and the like can be reliably discharged. Furthermore, since a cleaning agent is used in the cleaning process, depending on the components of the cleaning agent, iron or the like contained in tap water may adhere as soot to the inner peripheral surface of the hopper 3 after the cleaning process. On the other hand, in this embodiment, since the rinsing process is further provided after the cleaning process, the deposits can be removed.

[0127] Further, since the cleaning agent used in the cleaning process and the water used in the rinsing process are allowed to flow from the drain pipe connection port 8, the residue remaining on the drain plate connection port 8 and the bottom plate 10 below the hopper 3 is removed. Can be discharged.

Therefore, in this embodiment, the inside of the hopper 3 can be kept clean by providing a washing step and a rinsing step after the washing step.

In the above embodiment, in the cleaning process, the crushing unit 6 is driven in a state where the cleaning liquid is stored in the hopper 3 to clean the hopper 3. On the other hand, similarly to the rinsing process, the washing process may be performed while draining water without accumulating water in the hopper 3. At this time, since it is not necessary to store water in the hopper 3 in both the cleaning process and the rinsing process, it is not necessary to provide the drain opening / closing valve 52 of the drain pipe 50 of the disposer device 1.

[0130] [Second Embodiment]

Next, the present embodiment will be described with reference to the drawings.

[0131] In the first embodiment, the rinsing process is performed in a state where water does not accumulate in the hopper 3. On the other hand, the present embodiment is different from the first embodiment in that the rinsing process is performed with water stored in the hopper 3. The configuration of other disposer devices and the crushing and cleaning processes performed by this device are the same as those in the first embodiment, and therefore, common constituent elements are denoted by the same reference numerals and detailed description thereof is omitted. Omitted.

FIGS. 12 and 13 are flowcharts showing the operation of the cleaning Z rinse mode according to the present embodiment. Yat.

[0133] First, as shown in FIG. 12, when the user selects the cleaning Z rinsing mode, step S2

Cleaning to 0 Z rinsing is performed. The processes up to the cleaning process (steps S72 to S90) performed before the rinsing process are the same as those in the first embodiment.

[0134] When it is determined in step S90 that the drainage of the hopper 3 has been completed, the process proceeds to a rinsing process in step S102 (see Fig. 13).

[0135] As shown in FIG. 13, the rinsing process is started in step S102, and the control unit in step S104.

78 supplies a drain pipe closing signal to the drain on / off valve 52 of the drain pipe 50 and closes the drain on / off valve 52.

[0136] Next, when the drain on-off valve 52 is closed in step S106, the controller 78 supplies a connection pipe open signal to the water supply on-off valve 55 of the connection pipe 66, and the water supply on-off valve of the connection pipe 66 is supplied. Open 55. Thereby, automatic water supply from the water pipe into the hopper 3 is started.

[0137] Next, in step S108, the control unit 78 determines whether the water supply time set in advance by the timer has passed or not with reference to the time when the water supply opening / closing valve 55 is opened. The water supply time is, for example, the time that the supplied tap water does not overflow from the hopper 3, and is set to 15 to 20 seconds if the supplied tap water is 8 liters Z minutes. If the controller 78 determines that the set water supply time has elapsed, the water supply opening / closing valve 55 is closed in step S110 to stop water supply into the hopper 3. On the other hand, if the control unit 78 determines that the set water supply time has passed, the control unit 78 continues the water supply by opening the water supply opening / closing valve 55 of the connecting pipe 66 and keeping it open (step S). 108). As a result, since the drain opening / closing valve 52 of the drain pipe 50 is closed (step S104), a certain amount of tap water accumulates in the hopper 3.

Next, in step S112, when a certain amount of tap water is accumulated in the hopper 3, the control unit 78 supplies a drive signal to the drive motor 82 to drive the crushing unit 6 to rotate. The broken unit 6 is driven inversion every 5 seconds, for example. The tap water stored in the hopper 3 is distributed by the crushing unit 6 to the inner wall surface of the hopper 3, between the crushing blades of the crushing unit 6, and to the corners on the back side of the crushing blades. Thus, in the present embodiment, the crushing unit 6 is rotationally driven in a state where a certain amount of tap water is accumulated in the hopper 3 to perform the rinsing process. [0139] Next, in step S114, the control unit 78 determines whether or not the rinsing process has passed a preset rinsing time. The rinsing time is a time during which the cleaning liquid remaining after the cleaning process can be sufficiently drained, and is set to 60 seconds, for example. If the controller 78 determines that the set rinsing time has elapsed, the process proceeds to step S116. On the other hand, when it is determined that the set rinsing time has not elapsed, the rotational drive of the crushing unit 6 is continued (step S114).

[0140] Next, in step S116, the control unit 78 supplies a drive stop signal to the drive motor 82 to stop the rotational drive of the crushing unit 6 connected to the drive motor 82.

[0141] Next, in step S118, the controller 78 supplies a drain pipe open signal to the drain open / close valve 52 of the drain pipe 50. As a result, the drain open / close valve 52 of the drain pipe 50 is opened, and the water stored in the hopper 3 passes through the crushing unit 6, the bottom plate 10, and the drain pipe connection port 8 and is discharged into the discharge treatment tank. At this time, the cleaning liquid in the cleaning process inside the hopper 3, the crushed material in the crushing process, and the crushed material remaining in the bottom plate 10 and the drain pipe connection port 8 are simultaneously discharged.

[0142] Next, in step S120, the control unit 78 determines whether or not the drainage of the hopper 3 is completed based on whether or not the water detection sensor is detected. If the water detection sensor stops detecting water, the control unit 78 determines that the drainage of the hopper 3 has been completed, and the process proceeds to step S122. On the other hand, when the water detection sensor detects water, the controller 78 determines that the drainage of the hopper 3 has not been completed, and continues the process of step S120.

[0143] Next, in step S122, a buzzer sound is generated to notify the user of the end of the rinsing process. This buzzer sound may be generated when the rotation drive of the crushing unit 6 in step S116 is stopped.

[Third Embodiment]

Next, the present embodiment will be described with reference to the drawings.

[0145] In the first and second embodiments, the cleaning Z rinsing process is not performed unless the cleaning Z rinsing mode is selected. In contrast, the present embodiment is different from the first and second embodiments in that the cleaning Z rinsing process is automatically performed when the crushing process is performed a predetermined number of times. The configuration of other disposer devices and the crushing and cleaning processes performed by this device are the same as those in the first and second embodiments, so a common configuration is used. Elements are denoted by the same reference numerals and detailed description thereof is omitted.

FIG. 14 is a flowchart showing an example of the operation in the cleaning Z rinse mode according to the present embodiment.

[0147] Cleaning The Z rinsing mode is automatically started immediately after the crushing process is performed a plurality of times. Accordingly, first, in step S200, it is set how many times the “crushing mode” is executed and then the operation mode of the disposer apparatus 1 is shifted to the “washing / rinsing mode”. That is, here, the number of times of processing in the “crushing mode” is set. For example, if the crushing mode is selected three times a day and the washing Z rinsing mode is performed after the third crushing process, set “3”. The setting is performed by providing an operation unit having a numeric button for inputting the number of processing times of the “crushing mode” on the surface of the kitchen sink S, and selecting the numeric button of this operation unit. The input value is stored in the memory of the control unit 78 as a set value. Note that the method of inputting the number of processing times is not limited to the above method, and various methods can be employed.

[0148] Next, in step S202, the user selects an operation mode of the disposer device 1. When the “crushing mode” is selected, the process proceeds to step S204, and when the “cleaning Z rinsing mode” is selected, the process proceeds to step S210. Here, the case where the user selects the first crushing mode will be described.

[0149] In step S204, a crushing process is performed. As a result, the crushing unit 6 is rotated and water supply is started, and the crushed crushed material is discharged into the discharge treatment tank together with the water.

[0150] When the crushing mode is selected by the user, in step S206, the control unit 78 counts the number of times of processing in the crushing mode, and stores the counted number of times of processing in the memory. Here, the initial value n = 0 is stored in advance in the area where the processing count value of the memory is stored, and when the crushing mode is selected, the control unit 78 adds +1 to the initial value n. Then, the added value (number of processing times) n = 1 is stored in the memory.

Next, in step S208, the process count value added in step S206 is compared with a preset setting value. If the comparison indicates that the processing count value is equal to the set value, the process proceeds to step S210. On the other hand, when the processing count value is smaller than the set value, the processing returns to step S202, and the processing count value in the crushing mode reaches the set value count. If not, no wash Z rinse treatment is performed.

In the present embodiment, since the set value is set to “3”, the process returns to step S202. Such an operation (steps S202 to S208) is repeated until the preset set value is equal to the processing count value. When the “crushing mode” is selected three times, the processing count value becomes “3”, and the processing count value becomes equal to the set value, so that the process proceeds to the next step S210.

When the condition of step S208 is satisfied, in step S210, the “crushing mode” is automatically shifted to the “washing Z rinsing mode”, and the washing Z rinsing process is started. When the cleaning Z rinsing process ends, the process proceeds to step S212.

In step S212, the controller 78 initializes the processing count value n stored in the memory to 0.

When the memory is initialized, the process returns to the initial step S202. At this time, the process may return to step S200 for changing the number of times of processing (setting value) in the crushing mode for shifting to the “cleaning Z rinsing mode” set first.

[0155] In the above-described example, the force that has been shifted to the "cleaning Z rinsing mode" based on the number of times the crushing mode is selected. For example, a timer is provided in the control unit 78, and after a certain period of time or days have elapsed A configuration may be adopted in which the mode is automatically shifted to the “cleaning / rinsing mode”.

It should be noted that the technical scope of the present invention is not limited to the above-described embodiment, but includes various modifications to the above-described embodiment without departing from the spirit of the present invention. including.

However, the cleaning agent is attached to the lid 5, and the hopper is melted with tap water supplied with water. 3 Cleaning solution can be supplied inside!

[0158] In the above embodiment, the cleaning agent is automatically supplied. However, the user may supply the cleaning agent manually.

[0159] Furthermore, in the above embodiment, the present invention is applied to the grinder-type detachable disposer apparatus 1. However, not only the non-detachable disposer apparatus but also the hammer mill-type chain mill-type disposer apparatus. It can be easily understood that the present invention can be applied.

[0160] [Fourth embodiment] Next, a fourth embodiment will be described with reference to the drawings. In the present embodiment, a case where the drain pipe 50 used in the SI house is cleaned will be described. Since the configuration and the like of the other deposer devices are the same as those in the first to third embodiments described above, common constituent elements are denoted by the same reference numerals and detailed description thereof is omitted.

The upper end of the hopper 3 is fitted and fixed to the inside corresponding to the hopper 3 of the input opening 4 of the kitchen sink S through the attachment means 2 (shown by chain lines).

[0162] Inside the hopper 3, a crushing unit 6 is detachably attached to the hopper 3. The fracture unit 6 has a 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 7 a of the speed reduction unit 7. 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 7 as drive means (not shown) are installed therein. The drive motor rotates the rotary crushing blade of the crushing unit 6 through the speed reduction unit 7. The drive shaft 7a that transmits the driving force to the fractured frame unit 6 and the fitting portion 37 between the crushing unit 6 are formed in a square shaft shape or a spline shaft shape.

[0163] The hopper 3 is an upright cylindrical tubular body, and in this example, a pair of hoppers 3 extending downward from the charging opening 4 side of the hopper 3 at a position 180 ° apart in this example. The fitting portion (groove portion in this example) 3a is formed. The crushing unit 6 is inserted into and removed from the input opening 4 and is detachable from the hopper 3.

[0164] A drainage pipe connection port (drainage port) 8 is provided at the lower peripheral surface of the hopper 3, and a drainage pipe 50 is connected to the drainage pipe connection port 8. A drain opening / closing valve (for example, a solenoid valve) 52 is provided at the drain pipe connection port 8, and drainage is controlled by opening / closing the drain opening / closing valve 52.

[0165] Inside the hopper 3, a bottom plate 10 inclined to the drain pipe connection port 8 is provided, and the center portion of the bottom plate 10 serves as a bearing portion that receives the drive shaft 7a.

[0166] A lid 84 is detachably attached to the inside of the hopper 3 corresponding to the input opening 4. The When the deposer device 1 is used, the opening 84 is closed by the lid 84, so that hands and the like are not inadvertently inserted into the hopper 3 during the garbage treatment, and the crushed garbage is Kitchen Sink Do not scatter on the S side.

The drive motor is started in conjunction with the lid 84. For this purpose, a detecting means for detecting that the closing opening 4 is closed (locked) using a permanent magnet 83 provided on the lid 84 is provided. When it is detected that the closing opening 4 is closed by the magnetic sensor 232 provided on the hopper 3 side, the drive of the drive motor and the like are controlled by the control unit 78 described later (crushing mode).

[0168] The hopper 3 fitted with such a crushing unit 6 is attached and fixed to the kitchen sink S via the attachment means 2. The attachment means 2 has a flange 74, which is fixedly attached to the kitchen sink S, and the hopper 3 is fixed to the kitchen sink S through the flange 74.

[0169] A tap water supply port 9 is provided on the upper peripheral surface of the hopper 3, and a connecting pipe 66 connected to the water pipe is connected to the water supply port 9. A water supply opening / closing valve (for example, a solenoid valve) 55 is provided at the water supply port 9, and the water supply to the inside of the hopper 3 is controlled by the opening / closing operation of the water supply opening / closing valve 55.

[0170] The lid body 84 includes an upper lid 82a and an inner lid 82b, which are used by being integrated with screws (not shown). The internal space formed by the upper lid 82a and the inner lid 82b functions as a water storage part 72, and a lid for supplying tap water as shown in the figure at a predetermined position on the outer wall of the inner lid 82b. Body side water supply port 88 is provided. A water supply port 9 provided in the hopper 3 is located at a position facing the water supply port 88 on the lid side.

Next, the case where the disposer device 1 described above is installed in an SI house will be described with reference to FIGS. 15 and 16. Fig. 16 shows the configuration of the drain pipe 50 used in SI houses.

[0172] As shown in FIG. 16, the boundaries of each floor (rooms R1 to R3) of the apartment are partitioned by concrete slabs CS. Drainage mains 50b extending to the upper and lower floors are provided in common areas (for example, corridors) of apartment buildings. The drainage main pipe 50b and the drainage section of the room R2 (for example, the sink 100 shown in FIG. 16) are connected by a drainage side branch pipe 50c. One end side of the drainage horizontal branch pipe 50c is connected to the drainage main pipe 50b via the drainage pipe joint 54. As shown in FIG. 15, an S trap pipe 50 a bent in an S shape is connected to the drain pipe connection port 8 of the disposer device 1 installed in the sink 100 through a connecting pipe 51 as shown in FIG. The S trap pipe 50a and the drainage horizontal branch pipe 50c are connected to each other via the conversion adapter 57. Drainage from the disposer device 1 installed in the sink 100 is drained into the drainage main pipe 50b via the connecting pipe 51, the S trap pipe 50a and the drainage side branch pipe 50c (see arrow in FIG. 16).

[0174] In this way, the drain main 50b provided in the common section and the disposer device 1 installed in the sink 100 of the room R2 are provided at a distance D1 as shown in FIG. The length of the drainage side branch pipe 50c provided between the two is also increased. The drain pipe 50 includes an S trap pipe 50a, a drain main pipe 50b, and a drain side branch pipe 50c.

Next, the control of the disposer device 1 will be described with reference to FIG. 15 and FIG.

FIG. 17 is a block diagram showing a configuration of the disposer device 1. As shown in FIG.

[0176] The disposer device 1 has a control unit 78 that controls the operation of the disposer device 1 as a whole. The control unit 78 includes a CPU (Central Processing Unit), a ROM (Read Only Memory) that stores an operation program of the CPU, a RAM (Random Access Memory) that constitutes a work area of the CPU, and the like.

[0177] The lid 84 has a switch function for switching the operation of the disposer device 1 to the crushing mode. When the “crushing mode” is selected by the user, a crushing mode signal S is generated, and the generated crushing mode signal S is supplied to the control unit 78. The crushing mode signal S is generated in conjunction with the rotation operation of the lid 84 described later.

[0178] The control unit 78 is connected to an operation unit 67 for inputting information (conditions) for automatically shifting the operation of the disposer device 1 to the flushing mode. Examples of information input to the operation unit 67 include the total number of operations in the crushing mode, the number of days, and the time. When the information I input from the operation unit 67 satisfies a certain condition (see FIG. 18 to be described later), the control unit 78 shifts the disposer device 1 to the flushing mode and executes the flushing mode signals Ia to Id to be executed. Generated.

The drain on / off valve 52 provided at the drain pipe connection port 8 is connected to the control unit 78. When the information from the operation unit 67 satisfies a certain condition, the control unit 78 generates a drain pipe opening / closing signal la that opens and closes the drain opening / closing valve 52. The generated drain open / close signal la is the drain open of drain 50 This is supplied to the closing valve 52, and the opening / closing operation of the draining on / off valve 52 of the drain pipe 50 is controlled.

[0180] The water supply on-off valve 55 of the connecting pipe 66 is connected to the controller 78. When the crushing mode signal S is supplied from the lid 84, the control unit 78 generates an open / close signal Sb corresponding to the crushing mode. Further, when the information I from the operation unit 67 satisfies a certain condition, the control unit 78 generates an open / close signal lb corresponding to the flushing mode. The generated opening / closing signal Sb, lb is supplied to the water supply opening / closing valve 55 of the connecting pipe 66, and the opening / closing operation of the water supply opening / closing valve 55 is controlled.

A drive motor 82 that drives the crushing unit 6 is connected to the control unit 78. When the crushing mode signal S is supplied from the lid 84 or the information from the operation unit 67 satisfies a certain condition, the control unit 78 generates drive (or stop) signals Sc and Ic corresponding to each mode. And supplied to the drive motor 82. The drive motor 82 is driven by the supplied drive signals Sc and Ic, and rotates the crushing unit 6 in conjunction therewith.

[0182] The speaker 80 is connected to the control unit 78, and when the drive signal Sc, Ic is supplied to the drive motor 82 that rotationally drives the crushing unit 6, and after a certain time has passed, the control unit 78 sends an end signal Sd, Supply Id. The speaker 80 generates a buzzer sound for notifying the user of the end of the crushing process or the flushing process based on the end signals Sd and Id.

Next, the flushing mode mode will be described with reference to FIGS. 15 to 19.

FIG. 18 and FIG. 19 are flowcharts showing an example of the operation in the flushing mode of the disposer device 1 according to the present embodiment. In the following description, since a known method is adopted for the “crushing mode”, the description is omitted.

[0185] The flushing mode is automatically started immediately after the crushing process is performed a plurality of times. Accordingly, first, in step S300, it is set how many times the “crushing mode” is executed before the operation of the disposer apparatus 1 is shifted to the “flushing mode”. That is, here, the set value of “crushing mode” is input to the operation unit 67. For example, if the user selects the crushing mode three times a day, and enters the flushing mode after the 21st crushing mode selection one week later, enter the setting value “21”. The input value is stored in a memory included in the control unit 78 as a set value.

[0186] Next, in step S302, the user selects an operation mode of the disposer device 1. When “Fracture mode” is selected, the process proceeds to step S304.

[0187] In step S304, a crushing process is performed. As a result, the crushing unit 6 is rotated and water supply is started, and the crushed crushed material is sequentially discharged into the waste water treatment tank through the drain pipe 50 together with the water. In the crushing mode, the drain on-off valve 52 is assumed to be open.

[0188] When the crushing mode is selected by the user, the controller 78 counts the number of times of processing in the crushing mode, and stores the counted number of times of processing in the memory (step S306). Here, the initial value n = 0 is stored in advance in the area where the processing count value of the memory is stored, and when the crushing mode is selected, the control unit 78 adds +1 to the initial value n. Then, this added value (processing count value) n = 1 is stored in the memory.

Next, in step S308, the control unit 78 compares the process count value added in step S306 with the set value input to the operation unit 67. If the number of processing times is equal to the set value by this comparison, the process proceeds to step S310. On the other hand, if the processing count value is not equal to the set value, the process returns to step S302, and the flushing mode is not performed because the processing count value in the crushing mode has not reached the specified count “21”. Then, the operations of steps S302 to S308 are repeated until the preset setting value and the processing count value become equal. When the “crushing mode” is selected 21 times, the processing count value becomes “21”, and the processing count value becomes equal to the set value (step S308), so the process proceeds to the next step S310 (automatic transition).

[0190] In step S310, after the "crushing mode" ends, the mode automatically shifts to the "flushing mode", and the drain pipe 50 is flushed. The flushing mode will be described later. When the flushing process ends, the process proceeds to step S312.

[0191] In step S312, the control unit 78 initializes the processing count value n stored in the memory to zero. When the memory processing count value is initialized, the process proceeds to step S314.

[0192] In step S314, the user determines whether or not to change the setting value of the crushing mode set in step S300. If you want to change the setting value of crushing mode, proceed to processing force S step S300. On the other hand, when the processing frequency value in the crushing mode is not changed, the process proceeds to step S302. In the flowchart of FIG. 18, the setting of step S 200 can be separated from the operation mode (independently). In this case, step S200 and step S314 are not required, and the return mode is set after step S312.

[0194] Next, the flushing mode (step S310) will be described.

First, in step S320, the control unit 78 supplies the drain pipe closing signal la to the drain on / off valve 52 of the drain pipe 50, and closes the drain on / off valve 52.

[0196] Next, when the drainage on-off valve 52 is closed, in step S322, the control unit 78 supplies the communication pipe open signal lb to the water supply on-off valve 55 of the connection pipe 66, and the connection pipe 66 is opened and closed for water supply. Open valve 55. Thereby, automatic water supply from the water pipe to the inside of the hopper 3 is started.

[0197] Next, in step S324, the control unit 78 determines whether or not the water supply time set in advance by the timer has elapsed with reference to the time when the water supply opening / closing valve 55 is opened. The water supply time is a time during which a sufficient amount of water can be supplied for the cleaning process. In this example, the water supply time is set so that the supplied tap water does not overflow from the hopper 3. If tap water supplied is 8 liters Z minutes, it is set to 15 to 20 seconds.

[0198] If the control unit 78 determines that the set water supply time has elapsed, the control unit 78 proceeds to step S326. On the other hand, if the controller 78 determines that the set water supply time has not elapsed, the water supply on / off valve 55 of the connecting pipe 66 is kept open to continue water supply (step S324). As a result, since the drain opening / closing valve 52 of the drain pipe 50 is closed (step S320), a certain amount of tap water accumulates in the hopper 3.

Next, in step S326, the controller 78 closes the water supply opening / closing valve 55 and stops water supply into the hopper 3 inside.

Next, in step S328, the control unit 78 supplies the drain pipe open signal la to the drain on / off valve 52 of the drain pipe 50. As a result, the drain open / close valve 52 of the drain pipe 50 is opened, and the water stored inside the hopper 3 is drained to the outside of the hopper 3 at once. The water drained from the drainage pipe connection port 8 of the hopper 3 (flushing water) passes through the S trap pipe 50a and the drainage side branch pipe 50c, and is drained to the drainage main pipe 50b provided in the common area (Fig. 16). At this time, the flushed water (washed water) accumulates and accumulates crushed material in the S trap pipe 50a and the drainage side branch pipe 50c at the same time as the drainage main pipe 50b. (Step S330).

[0201] Next, in step S332, the control unit 78 detects whether or not the drainage of the hopper 3 has been completed. Drainage completion is detected by installing a water detection sensor below or on the bottom surface of the inner periphery of hopper 3 and detecting the end of drainage inside hopper 3 when the signal detected by the water detection sensor is turned off. . When the control unit 78 detects the completion of drainage, the control unit 78 generates a buzzer sound to notify the end of drainage from the speaker 80. Another method for detecting wastewater is to calculate the time of water drained from the hopper 3 from the amount of drainage drained from the drain pipe connection port 8 in advance, and when the calculated time has elapsed, the drainage is completed. It is also possible to judge.

In this embodiment, after a certain amount of water is accumulated in the hopper 3, the drain opening / closing valve 52 is opened and drained into the drain pipe 50. For this reason, the amount of water discharged into the drain pipe 50 per unit time is larger than in the crushing mode in which crushing is performed while sequentially draining water with the drain opening / closing valve 52 opened. As a result, the collected water flows into the drain pipe 50 all at once, and the soot accumulated in the drain pipe 50 is also discharged at once by this water flow. As a result, the drain pipe 50 is cleaned, and the drain pipe 50 is prevented from being clogged.

[0203] In the above embodiment, the force that has been shifted to the flashing mode based on the number of times the crushing mode has been selected. For example, a timer is provided in the control unit, and after a certain period of time or number of days has passed, It is good also as a structure which shifts to flushing mode in general.

[0204] [Fifth embodiment]

Next, the present embodiment will be described with reference to the drawings.

[0205] In the first embodiment, the mode is automatically shifted from the crushing mode to the flashing mode by inputting a set value. On the other hand, this embodiment is different from the first embodiment in that the user switches to the flashing mode to execute the flushing mode (the point that there is no operation unit 67 in FIG. 17). Since the configuration of the other disposer device 1 is the same as that of the first embodiment, common constituent elements are denoted by the same reference numerals and detailed description thereof is omitted.

FIG. 20 shows a top view of the lid 84 that switches the operation of the disposer device 1. The lid 84 functions as mode selection means. As shown in Figure 20, around the outer edge of the lid 84 Is fitted with a flange 74. On the flange 74, the characters “OFF” are written, and the characters “crushing mode” are written at a position rotated from the “OFF” written position by 60 ° clockwise in the illustrated state. On the other hand, the characters “Flushing Mode” are displayed at a position rotated 60 ° counterclockwise from the “OFF” position. Corresponding to the position where each mode of the flange 74 is indicated, the lid 84 is provided with a magnet 83, for example, and a proximity sensor 232 is provided at the position of the hopper 3 facing this (see FIG. 15). ). Then, when the lid 84 is rotated to each mode position, the operation mode of the disposer device 1 is switched to each mode described above. Thus, the lid 84 functions as a switch for switching the operation mode of the disposer device 1.

[0207] Next, the operation of the disposer device 1 will be described. FIG. 21 is a flowchart showing the operation mode switching operation of the disposer device 1. The operation in the flushing mode is the same as that in FIG. 19 of the first embodiment, and the description is omitted.

[0208] First, in step S400, the user selects an operation mode of the disposer device 1.

The operation mode is selected by rotating the lid 84 from “OFF” to “crushing mode” or from “OFF” to “flashing mode”. Here, when “crushing mode” is selected, the process proceeds to step S404, and when “flushing mode” is selected, the process proceeds to step S402.

[0209] In step 404, a crushing process is performed, and in step S402, a flushing process is performed. When the processing of steps 402 and 404 is completed, a buzzer sounds to notify the end of the crushing mode and the flashing mode. Based on the buzzer sound, the user returns the lid 84 from the “crushing mode” to the “OFF” position when “breaking frame mode” is selected. On the other hand, when “flushing mode” is selected, the lid 84 is returned from the “flushing mode” to the “OFF” position. That is, the lid 84 is returned to the initial standby position (step S406).

[0210] Generally, after the processing in the "crushing mode" is completed, the "flushing mode" is selected to drain the soot that accumulates and accumulates in the drain pipe 50. Therefore, if “Fracture mode” is selected in Step S400, “Flushing mode” is selected in Step S406. You may make it.

[0212] [Sixth embodiment]

Next, the present embodiment will be described with reference to the drawings.

[0213] This embodiment is different from the first and second embodiments in that the crushing unit is driven and the cleaning agent is supplied to the inside of the hopper 3 until the water supply start force in the flushing mode is completed until the drainage is completed. Different. Since the configuration of the other disposer device 1 is the same as that of the first and second embodiments, common constituent elements are denoted by the same reference numerals and detailed description thereof is omitted.

FIG. 22 is a diagram showing a configuration of the disposer device 1 according to the present embodiment. As shown in FIG. 22, a cleaning agent storage tank 62 for storing the cleaning agent is provided on the outer periphery of the hopper 3 on the back side of the kitchen sink S via the mounting table 43. The cleaning agent storage tank 62 is an example of cleaning agent supply means. A predetermined amount of cleaning agent is stored in the cleaning agent storage tank 62. As the cleaning agent, for example, a general neutral detergent, an enzyme that decomposes oil, a product that removes slime, a product that has functions such as sterilization, disinfection, fragrance, mold prevention, and generation control of microorganisms are preferably used. It is done. In addition, the cleaning agent may be a solid, gel, or liquid! /, Misalignment type.

[0215] A cleaning agent injection pipe 64 for connecting the cleaning agent storage tank 62 and the disposer device 1 is attached to the lower side surface of the cleaning agent storage tank 62. This cleaning agent injection pipe 64 is an example of a cleaning agent supply means. The cleaning agent injection pipe 64 is provided with a cleaning agent on-off valve (for example, a solenoid valve) 60 for controlling the injection amount of the cleaning agent. The on-off valve for the cleaning agent is interlocked with the change of the operation mode of the disposer device 1. 60 opens and closes. When the cleaning agent on / off valve 60 is closed, the cleaning agent is injected into the hopper 3 by the weight of the cleaning agent. Further, the cleaning agent storage tank 62 is installed at a position where the cleaning agent injection pipe 64 is higher than the surface of the water stored in the hopper 3. As a result, the cleaning agent collected in the water inside the hopper 3 is collected. Back flow to the tank 62 is prevented.

It should be noted that the cleaning agent storage tank 62 may be installed detachably with respect to the kitchen sink S and the disposer device 1 or may be configured integrally with the disposer device 1. The cleaning agent storage tank 62 itself may be replaceable. In the example shown in FIG. 22, the cleaning agent storage tank 62 is installed above the protruding portion 3b of the hopper 3 via the mounting table 43. However, the position where the cleaning agent storage tank 62 is installed is limited to this. It will never be done. Furthermore, the method of injecting the cleaning agent from the cleaning agent storage tank 62 to the hopper 3 is to provide a pump in the cleaning agent storage tank 62 and drive this pump to inject the cleaning agent into the hopper 3. Also good.

[0217] The operation of the flushing mode using such a disposer device 1 will be described below.

[0218] The flushing mode of the present embodiment is performed after the start of water supply to the inside of the hopper 3 (step S322) shown in FIG. 19 until the drainage of the inside of the hopper 3 is completed (step S332). The crushing unit 6 is driven to rotate. In other words, the crushing unit 6 is driven to rotate while any of the water is stored in the hopper 3. As a result, the water stored inside the hopper 3 is stirred by the crushing unit 6 and reaches the inner peripheral surface of the hopper 3, between the crushing blades and the back side of the crushing blade, and the inside of the hopper 3 is simultaneously cleaned. Is called.

[0219] When the crushing unit 6 is driven to rotate, the cleaning agent on-off valve 60 of the disposer apparatus 1 shown in Fig. 22 is opened, and the cleaning agent is supplied from the cleaning agent storage tank 62 to the inside of the hopper 3. Also good. As a result, the cleaning liquid is stirred by the crushing unit 6 and reaches the inner peripheral surface of the hopper 3, the space between the crushing blades, and the back surface side of the crushing blades, and the cleaning effect can be further improved.

[0220] It should be noted that the technical scope of the present invention is not limited to the above-described embodiments, but includes those in which various modifications are made to the above-described embodiments without departing from the spirit of the present invention.

For example, in the above-described fourth to sixth embodiments, the case where the disposer device 1 is applied to an SI house has been described. However, the present invention can also be applied to a general house or the like. That is, it can be applied to all drain pipes. [0222] Furthermore, in the above embodiment, the force is applied not only to a non-detachable disposer apparatus in which the present invention is applied to a grinder-type detachable disposer apparatus, but also to a hammer mill type or a chain mill type disposer apparatus. It can be easily understood that the invention can be applied. Further, in the above-described embodiment, the force of supplying water from the water supply port 9 provided on the upper peripheral surface of the hopper 3 to the inside of the hopper 3 through the storage portion 72 of the lid 84 is not limited to this. A configuration may be adopted in which water is automatically supplied to the disposer device 1 by controlling the electromagnetic on-off valve provided on the faucet from the faucet with an electromagnetic on-off valve provided around S. The point is that the water supply to the disposer apparatus 1 may be automatically supplied to the inside of the disposer apparatus 1 via a solenoid valve or the like.
