Description

  The present invention relates to a garbage disposal apparatus that can be used by being connected to a sink called a deposer, or can be carried or moved to be used at an arbitrary location.

  The basic configuration of the desposer attached to the sink is such that pulverization blades are provided in a pulverization chamber continuous to the sink, and pulverized garbage is discharged from the pulverization chamber through a mesh (Patent Document 1).

  In the above basic configuration, there is a risk of reaching the grinding chamber (Problem A), and the crushed dust adheres to the wall of the grinding chamber, causing bad odor and requiring cleaning (Problem B). Driving the motor in the water supply state causes motor baking, and a predetermined control is required for the pulverization operation and pulverized garbage outflow (Problem C). Further, the pulverized raw garbage is discharged naturally and there is a risk of clogging. There are some problems (Problem D).

  As a countermeasure against the problem C, Patent Document 2 discloses a configuration in which a flow rate detection switch is provided in a water supply pipe and a motor is operated while water is being supplied to a sink. Patent Document 3 discloses a configuration in which a crushing chamber is provided with a lid, the switch is turned on and off by opening and closing the lid, and water is supplied to the crushing chamber for a certain period of time including before the motor is operated.

  In addition, as a countermeasure against pipes caused by the natural flow of pulverized raw garbage (countermeasure for Problem D), Patent Document 4 discloses a configuration in which a waste water obtained by solid-liquid separation of a waste water from a desposer is circulated and transported by a jet pump. In Patent Document 5, a configuration is disclosed in which drainage from a deposer is discharged to a predetermined location by a transport flow (air mixing).

FIG. 1 of JP-A-8-290073. JP 2001-259463 A. JP-A-9-85119. JP 2000-282535 A. JP2003-1133A.

  As measures against pipe clogging, the forced discharge means disclosed in Patent Documents 4 and 5 described above requires a forced discharge device that is independent of the deposer device for the existing sink. .

  Accordingly, the present invention provides a novel sink garbage processing apparatus that can be compactly configured as a whole even if it is provided with a forced discharge means, and that can be easily provided with a new crushing mechanism. Is proposed.

The garbage processing apparatus according to the present invention includes a crushing mechanism for finely crushing garbage with a rotary cutting blade in a crushing chamber having a predetermined volume, and a discharge capable of forcibly discharging waste water containing pulverized material in the crushing chamber. Provided with an appropriate water level sensor having different detection water levels for controlling each operation of the crushing mechanism and the discharge mechanism in the crushing chamber. An object to be crushed , provided with an overflow drain portion provided, mounted on a rotating shaft mounted with a rotary cutting blade in the crushing mechanism so as to face the cutting blade body so as to be freely rotatable, and has an appropriate rotational resistance It is characterized by providing a blade body for preventing entanglement .

Therefore, the garbage thrown into the pulverization chamber is pulverized by the pulverization mechanism, and at the same time, the pulverized material is forcibly discharged from the pulverization chamber together with the drainage. functions as a device, further by an overflow drain portion with a perforated plate, while being drained from the overflow unit when the amount of water flowing into the grinding chamber is large, and Desupoza device without operating the grinding mechanism and the discharge mechanism When not used, it is drained from the overflow drainage section. In addition, the rotation of the rotary cutting blade causes the waste water in the crushing chamber to be in a vortex state. As a result, the blade body rotates at a speed slower than that of the rotary cutting blade body, and reaches the cutting blade portion. In addition to restricting the amount of raw garbage, the raw garbage, which is a long fiber such as a cocoon, directly reaches the rotary blade portion and does not get entangled with the rotary cutting blade body.

  Moreover, the garbage processing apparatus according to the present invention (Claim 2) is a total discharge part in which a drain pipe is connected to a mouthpiece opening provided at the lowermost part of the crushing chamber and an open / close valve is provided in the drain pipe. When the crushing mechanism and the discharge mechanism are not used without being operated with the deposer device, the on / off valves of all the discharge units that are closed during the crushing operation are opened, and the overflow discharge unit is opened. The crushing chamber can be used as a simple drainage passage without waiting for drainage.

In addition, the present invention (Claim 3 ) employs a submersible pump as the discharge mechanism, and the configuration in which the drive motor of the submersible pump is also used as the drive motor of the crushing mechanism, further reducing the size of the entire apparatus. To do.

Moreover, the garbage processing apparatus according to the present invention (Claim 4) is the above-described garbage processing apparatus, wherein the garbage storage chamber and the garbage storage chamber and the grinding chamber are connected between the grinding chamber and the sink. A garbage storage mechanism composed of trapping pipes that intervene. The garbage is temporarily stored in the storage chamber and sent to the crushing and discharging mechanism (garbage processing device) together with the wastewater to process the garbage. It is.

  As described above, the present invention provides a forced discharge mechanism such as a submersible pump or a forced discharge pump in the pulverization chamber, so that the forced discharge of pulverized garbage can be realized simply by incorporating the device of the present invention into the sink. By preventing the occurrence and further providing an overflow drainage section, it is possible to use both normal drainage and a deposer device.

  Furthermore, by attaching a whole drainage part (Claim 2), it can also be used as normal drainage without retaining drainage in the grinding chamber.

  In particular, by providing a free-rotating blade body that faces and faces the cutting blade portion (claim 3), entanglement of the raw garbage with the cutting blade body is prevented, and reliable pulverization of the raw garbage is realized.

  Furthermore, by adopting a submersible pump as the discharge mechanism, the pump drive motor is also used as a garbage crushing motor (Claim 4), thereby further reducing the size of the entire apparatus.

  Further, if a garbage storage mechanism having a trap tube is provided between the crushing chamber and the sink (claim 5), it is possible to block the odor from the garbage crushing chamber from rising to the sink.

  Next, an embodiment of the present invention will be described. The garbage processing apparatus shown in the embodiment includes a crushing and discharging mechanism unit 1 and a garbage storage mechanism unit 2.

  The pulverizing / discharging machine unit 1 includes a pulverizing / discharging unit 12 and a water level sensor 13 provided in the pulverizing chamber 11, an input unit 14, an overflow draining unit 15, and a total discharging unit 16 disposed in the pulverizing chamber 11.

  The crushing chamber 11 has an appropriate volume determined by the amount of dust to be crushed once.

  The crushing and discharging unit 12 includes a submersible pump 121, a cutting blade unit 122, a blade body 123, a pump discharging pipe 124, and a circulation pipe (circulation mechanism) 125.

  The submersible pump 121 is provided with a suction port in the peripheral portion of the rotating shaft, and a cutting blade portion 122 is disposed immediately before the suction port. The cutting blade part 122 is composed of a rotary cutting blade body 122a mounted on the rotary shaft and a fixed cutting blade body 122b that slides on the rotary cutting blade body 122a, and cuts garbage by the repulsive action of both cutting blade bodies. It is to be crushed. In particular, the fixed cutting blade 122b is provided across the opening of the cylindrical portion raised around the suction port.

  The blade body 123 is close to the cutting blade portion 122 (on the opposite side to the suction port) and is mounted on a rotation shaft so as to be freely rotatable. The blade body 123 does not have a flat plate parallel to the rotation plane, and has an appropriate rotational resistance. The shape is provided.

  The pump discharge pipe 124 is connected to a discharge location outside the apparatus such as a sewer pipe. The circulation pipe 125 is branched from the discharge pipe 124 and returns the waste water to the pulverization chamber 11. The circulation pipe 125 is smaller in diameter than the pump discharge pipe 124 and has a rising portion, or is provided with an open / close valve. The circulation is stopped naturally or by valve control when there is a decrease.

  The water level sensor 13 detects the water level in the crushing chamber 11 and is installed at a water level corresponding to the control target. At least the upper level sensor 131 for starting the driving of the crushing discharge unit 12 is stopped. A lower sensor 132 is provided.

  The input part 14 is provided in the upper part of the crushing chamber 11 and serves as an inlet for the garbage A. In this embodiment, the input part 14 is not in communication with the garbage storage mechanism part 2.

  The overflow drainage unit 15 is provided with an eye plate opening 151 in the upper part of the crushing chamber 11, and a drain pipe 152 is connected to the eye plate opening 151.

  The total discharge part 16 is configured such that a drain pipe 162 is connected to a pan opening 161 provided at the lowermost part of the crushing chamber 11, and an open / close valve 163 is provided in the drain pipe 162.

  The garbage storage mechanism 2 includes a garbage storage chamber 22 provided with an opening / closing lid 21 at an appropriate location on the bottom surface of the sink B, and a water supply unit (water supply tank) that can discharge the garbage A in the garbage storage chamber 22 at a stretch. 23, an open / close valve 24, and a water supply pipe 25), a lowermost part of the garbage storage chamber 22 and the input part 14 are connected to each other, and a trap pipe 26 that exhibits a siphon action is formed.

  In addition, in the said garbage storage mechanism 2, you may make it implement the effect | action similar to a water supply part by the arbitrary waste_water | drain from a sink, without providing a water supply part.

  In addition, appropriate control means such as a control circuit for controlling the operation of the drive motor of the submersible pump 121 based on detection of the water level sensor 13 and controlling the opening / closing operation of the valves of the respective parts is provided as necessary. You should be prepared.

  Thus, the open / close lid 21 of the garbage storage chamber 22 provided on the bottom surface of the sink B is opened, the garbage A is put in, the open / close lid 21 is closed, and an operation start instruction (turns on a switch provided in the control unit). As a result, the opening / closing valve 24 is opened and a predetermined amount of transport water is supplied from the water supply tank 23, and the garbage A enters the crushing chamber 11 through the trap pipe 26 together with the transport water. When the water supply part is not provided, the garbage A can be sent into the crushing chamber 11 by flowing a necessary amount of water through the sink with the open / close lid 21 opened.

  When the garbage A in the garbage storage chamber 22 flows into the pulverization chamber 11, the trap pipe 26 seals the space between the pulverization chamber 11 and the garbage storage chamber 22. The odor will be cut off.

  In the crushing chamber 11, when the upper sensor 131 detects the water level of the crushing chamber 11, the submersible pump 121 is operated to finely cut and crush the garbage A with the cutting blade 122, and the pulverized product is submerged in the submersible pump 121. Then, together with the drainage, it is discharged from the pump discharge pipe 124 to a predetermined location (such as a sewer pipe). Of course, the suction side of the submersible pump 121 is naturally provided with a screen for sucking only the pulverized material having a predetermined size or less.

  Then, when all of the pulverized material and waste water are discharged and the lower sensor 132 detects that the water level in the pulverization chamber 11 is the lowest water level, the submersible pump 121 is stopped. As a result, the garbage A is crushed and forcibly discharged. Therefore, even if the drain pipe is clogged with the pulverized material, the clogging is eliminated by the pressure of the next forced drainage. Become.

  When the water level in the crushing chamber 11 is higher than the planned water level, the water is discharged from the overflow drainage unit 15.

  Further, when discharging the pulverized material, a part of the waste water may be returned to the pulverization chamber 11 again through the circulation pipe 125, and a part of the discharged water may be circulated to secure the pulverization time. This circulation mechanism is not always necessary.

  When the crushing operation in the crushing chamber 11 is not performed (when used only for normal drainage), the on-off valves 163 of all the discharge sections 16 that are closed during the crushing operation are opened, and the crushing chamber 11 is opened. It can be used as a simple drainage passage.

  Although the garbage storage mechanism 2 shown in the embodiment is interposed between the sink B and the garbage disposal apparatus of the present invention only with the crushing and discharging mechanism, Therefore, safety considerations such as attaching an open / close lid are necessary.

  Furthermore, the device of the present invention is not necessarily fixedly connected to the sink, and can be carried or used indoors as a device that can be moved together with the garbage storage mechanism or the crushing and discharging mechanism unit alone. You can also

  Further, as illustrated in FIG. 2, the present invention may be configured such that the pulverization mechanism of the pulverization discharge unit 12 in the pulverization chamber 11 uses a unique motor 126 without using the motor of the submersible pump 121. Good (note that the numbers shown are the same as those in FIG. 1).

  Furthermore, as illustrated in FIG. 3, the present invention does not employ a submersible pump as the discharge mechanism, but attaches a discharge blade 127 to the drive motor 126 of the crushing mechanism, and rotates the blade 127 around the blade 127. The forced discharge mechanism may be adopted in such a shape that the crushed material-containing water raised in step 1 is pushed out to the discharge pipe 128.
