Description

  The present invention relates to a sink slag treatment apparatus that pulverizes cocoons generated in a kitchen by a slag pulverization apparatus and causes the slag to flow out to a sewer pipe or the like through a drain line of the sink.

  Conventionally, a household sink slag treatment device has a soot smashing device attached between the sink outlet of the sink and the drain pipe. In order to make it easy to discharge the processed material after pulverizing the cocoon, a certain amount of water is required for the pulverizer, and as a technique for automatically performing the water supply, There is a system in which a primary water supply system branched from the water is drawn into a sink and an electromagnetic valve is provided, and the electromagnetic valve is opened in a timely manner to automatically supply water to the inside of the pulverizer. (For example, refer to Patent Document 1).

  In the above technology for automatically supplying water to the pulverization treatment device, the primary water supply system was directly connected to the pulverization treatment chamber of the pulverization treatment device, causing water breakage when the solenoid valve was open. At this time, the inside of the water supply pipe becomes negative pressure, and there is a risk that the sewage in the pulverization chamber will flow back deep into the water supply system due to the reverse siphon action.

  In order to prevent the backflow, it is conceivable to provide a vacuum breaker in the water supply system from the electromagnetic valve to the pulverizer, but a generally used vacuum breaker is used as shown in FIG. 5, for example. .

  In FIG. 5, 1 is a sink sink, 2 is a top plate of the sink, 3 is a drain outlet, 4 is a pulverization processing device, 4a is a pulverization processing chamber in the culm pulverization processing device 4, 5 is a vacuum breaker, and 6 is primary. A side water supply system, 7 is a secondary side water supply system, 8 is a T joint for connecting the primary side water supply system 6 and the secondary side water supply system 7, and 9 is a check valve.

  In FIG. 5, a check valve 9 is provided between the vacuum breaker 5 and the feed water inlet of the slag crushing treatment device 4 in consideration of the case where the vacuum breaker 5 has malfunctioned. However, in this case, the crushed garbage pieces may adhere to the check pipe installed in the water supply pipe or in the vicinity thereof, and the function of preventing the backflow may be impaired.

JP 2000-5620 A

  In the structure shown in FIG. 5, the vacuum breaker 5 must be installed at a position 150 mm higher than the top plate 2 according to the regulations of the Air Conditioning and Sanitation Engineering Society (SHASE-S206), and the water supply on the primary side of the vacuum breaker 5 In order to raise the system 6 and the secondary water supply system 7 above the top plate 2, it is necessary to provide two holes in the top plate, and there are problems in the installation location of the vacuum breaker 5 and design issues, The structure around the vacuum breaker 5 is lacking in compactness.

  Moreover, in the conventional vacuum breaker 5 equipped with the valve body made into the float, the float floats with the water pressure at the time of water supply, and the air intake for the negative pressure destruction is plugged with the float, and the water overflows from the air intake Although water is not used, water may splatter at the start of water supply.

  An object of this invention is to provide the sink treatment apparatus which can mainly eliminate the above problems.

  In order to achieve the above object, according to the present invention, as described in claim 1, a sink slag treatment device in which a smashing treatment device is attached to the bottom of the drain of the sink of the sink is provided. Between the water supply port formed in the main body and the solenoid valve that supplies and stops water, and with respect to the top surface of the top plate of the sink, the primary flow path and the secondary flow path are on the same main body side. The vacuum breaker provided is provided in a projecting manner, and a check valve is provided between the vacuum breaker and the primary water supply system communicated with the primary flow path of the vacuum breaker.

The above-described invention is preferably embodied as follows.

Therefore, the appearance on the top plate around the vacuum breaker will be simplified and a clean feeling will be exhibited, so that the vacuum breaker can be attached to the sink without causing the installation location of the vacuum breaker, In addition, the appearance around the vacuum breaker can be made excellent, and the structure around the vacuum breaker can be made compact.

  In addition, when water is accidentally cut off while supplying water to the smashing treatment device through the solenoid valve and vacuum breaker, negative pressure is generated in the water supply system due to reverse siphon action, and the smashing is caused by the negative pressure. The filth in the treatment device tries to flow back into the water supply system through the water supply port of the main body, but as soon as the backflow occurs, the check valve closes to prevent the backflow, and the negative pressure As a result of this, the air is rapidly taken into the water supply system from the vacuum breaker, so that the negative pressure is instantaneously destroyed. The situation of the reverse flow deep inside is surely prevented, and the reverse flow due to the reverse pressure from the secondary side water supply system is also prevented.

According to the third aspect of the present invention, the through hole becomes the same size as the mounting hole of the mixing faucet, and it is convenient for compactly fixing the vacuum breaker to the lateral part of the mixing faucet at the top plate part of the sink. In addition, it is possible to connect the primary side water supply system and the secondary side water supply system to the lower surface of the vacuum breaker body without waste and without trouble, and furthermore, the mounting hole of the mixing faucet and the vacuum Since the breaker mounting through-hole can be formed with the same processing tool, it is rational in the production of the sink device.

  According to the invention described in claim 4, the vacuum breaker is firmly fixed to the top plate of the sink so that the upper portion thereof is located on the top plate and the lower portion is located below the top plate. In addition, the primary water supply system and the secondary water supply system can be connected to the lower surface of the main body of the vacuum breaker without any trouble, which contributes to making the vacuum breaker more compact.

  According to the invention of claim 5, since the upper part of the main body of the vacuum breaker is substantially concentric with the lower part of the main body and has a cylindrical shape with a larger diameter than the lower part, the valve element is placed in the upper part of the main body of the vacuum breaker.

Embodiments of the present invention will be described below.
FIG. 1 is a schematic view of a sink-top treatment device according to an embodiment of the present invention, FIG. 2 is a schematic view in which a part of the tray-treatment device is omitted, and FIG. 3 is a vacuum breaker mounting structure of the sink-top treatment device. FIG. 4 is a diagram showing a flow of the operation of the sink stand processing apparatus.

  1 and 2, the pulverization processing device 4 has a main body part 4A inside a pulverization processing chamber 4a, and the main body part 4A has a water supply port 4b communicating with the pulverization processing chamber 4a. . The inlet of the pulverization processing device 4 communicates with the drain port 3 on the bottom surface of the sink 1 and can be closed by a lid 4c, and the treated product outlet 4d of the pulverization processing device 4 is connected to the drain pipe 3A. Has been. A motor 4B for pulverization is fixed below the main body 4A.

  The vacuum breaker 5 is of a deck installation type, and as shown in FIGS. 2 and 3, etc., the main body made of a cylindrical body is the main body, and the main body has an upper portion 5A having a cylindrical outer peripheral surface. And the lower part 5B. The upper part 5A is substantially concentric with the lower part 5B and has a larger diameter than the lower part 5B. A radial surface part 5C is formed at the boundary between the upper part 5A and the lower part 5B, and the lower part 5B is a male screw part. The screw portion 5B is screwed onto the nut body 5D from the lower end side thereof.

  An air intake 5a (not shown) is formed on the top surface of the upper part 5A, and a valve body 5b for opening and closing the air intake 5a is installed inside the upper part 5A. At this time, the air intake 5a Is opened when the valve body 5b is lowered, and is closed when the valve body 5b is raised. In addition, in order to prevent other things from entering through the air intake port 5a and water overflowing due to a malfunction, the upper 5A is provided with a cover (not shown) covering the outer peripheral surface and the top surface of the upper 5A. The cover also functions as a guide means for causing water that has overflowed from the air intake port 5a to flow down into the sink 1 through the top plate 2.

  A water supply inlet a1 and a water supply outlet b1 are formed on the lower surface of the lower part 5B, and these water supply inlet a1 and water supply outlet b1 are communicated with each other through a water supply passage in the main body. The water supply passage in the main body has a primary flow path a2 communicated with the water supply inlet a1, a secondary flow path b2 communicated with the water supply outlet b1, and the primary flow path a2 and the secondary flow path b2. And a combined flow path through which air flows from the air intake port 5a by opening the valve body 5b. At this time, the relationship between the valve body 5b, the water supply inlet a1 and the water supply outlet b1, and the water supply passage in the main body from the water supply inlet a1 to the water supply outlet b1 is as follows, that is, the specific pressure from the water supply inlet a1. When the feed water flows in, the valve body 5b is immediately lifted and displaced by the pressure to close the air intake port 5a. In the closed state, the water feed passage in the main body connects the feed water outlet b1 and the feed water inlet a1 in a sealed manner. On the other hand, if the negative pressure acts on the water supply inlet a1 or the water supply outlet b1 because the water supply from the water supply inlet a1 is cut off, the valve body 5b immediately descends to open the air intake 5a. Then, the air flows into the coupling flow path of the water supply passage in the main body, the inflow destroys the negative pressure inside the water supply passage in the main body, and the water supply outlet b1 and the water supply inlet a1 are hermetically communicated. No longer Uninasa are.

  A through hole serving as a mounting hole 2a having a diameter of about 35 mm to 38 mm is formed in the top plate 2 of the sink. When the vacuum breaker 5 is fixed, a male screw portion 5B is inserted from above the hole 2a, and an upper portion 5A. 5C is brought into contact with the upper surface of the top plate 2, and then the synthetic rubber packing 10 and the polyethylene packing 11 are externally inserted into the male screw portion 5B, and the nut body 5D is screwed into the male screw portion 5B. Wear and conclude. At this time, the height from the radial surface portion 5C to the air intake 5a matches the height from the upper edge (overflow edge) of the sink 1 to the air intake 5a, and the size is 25 mm or more. The size is close to 25 mm. The dimension of 25 mm satisfies the SHASE regulations, and the negative pressure fracture performance can be reduced to 13 mm or less without hindrance.

  A primary water supply system 6 extends from the water supply inlet a1 of the vacuum breaker 5, and a check valve 9 and a solenoid valve 10 are mounted in this order toward the upstream side in the water supply system 6. The order of the solenoid valve 10 and the check valve 9 may be reversed. The former end of the water supply system 6 is connected to the water supply 6A. A secondary-side water supply system 7 extends from the water supply outlet b <b> 1 of the vacuum breaker 5, and the tip of the water supply system 7 is connected to the water supply port 4 b of the main body 4 </ b> A of the soot pulverization processing device 4.

The electromagnetic valve 10 is connected to a control panel 11 of the soot pulverization processing device 4 and is controlled to be opened and closed by the control panel 11 in relation to the operation of the soot pulverization processing device 4. The control panel 11 is connected to a switch 12 interlocked with the lid body 4c of the smashing processing device 4, and the switch 12 is turned ON by completely closing the lid body 4c, whereby the smashing processing device 4 A signal for starting the crushing processing operation is input to the control panel 11, and the switch 12 is turned off by opening the cover 4c, whereby the control panel 11 operates the crushing processing device 4 in the crushing processing operation. It will be in the state that does not occur.
In FIG. 1, 13 is a mixing faucet, and 14 is a hot water system.

Next, an example of use and operation of the above-described sink pallet treatment apparatus will be described with reference to FIG.
As shown in step 100, after the raw garbage generated in the kitchen is put into the pulverization processing chamber 4a of the pulverization processing apparatus 4, the lid 4c is completely closed. As a result, as shown in step 101, the switch 12 interlocked with the lid 4c is turned on and the electromagnetic valve 10 is opened.

  When the electromagnetic valve 10 is opened, the water in the water 6A flows into the main body water supply passage through the primary side water supply system 6, the electromagnetic valve 10, the check valve 9, and the water supply inlet a1. The inflowing water pushes the center of the valve body 5b right above by the water pressure, and the valve body 5b smoothly moves upward in a good balance state and closes the air intake port 5a. Therefore, no water leaks from the air intake 5a in the proper operating state.

  When the air intake 5a is closed, the water supply passage in the main body from the water supply inlet a1 to the water supply outlet b1 is sealed, and all the water that has flowed into the water supply passage in the main body passes through the water supply outlet b1 and is supplied to the secondary side. It flows out to the system 7. As a result, as shown in step 102, water is supplied at an appropriate flow rate into the pulverization chamber 4a through the water supply port 4b of the main body 4A of the soot pulverization apparatus 4.

  Next, as shown in step 103, after 5 seconds elapse from the time point when the switch 12 is turned on, the control panel 11 starts the motor 4B of the kneading crusher 4 to start the crushing operation. Thereby, as shown in step 104, the garbage in the crushing processing chamber 4a is crushed. The object to be processed thus pulverized is discharged to the outside through the drain pipe 3A with water continuously supplied from the water supply port 4b.

  Next, as shown in step 105, after the control panel 11 performs the crushing operation of the soot crushing device 4 for 60 seconds, for example, the motor 4B is automatically stopped to stop the crushing operation. Thereby, as shown in step 106, the crushing processing operation of the soot crushing processing device 4 is stopped. Since the water supply from the water supply port 4b is continuously performed even in the stopped state, the object to be processed in the pulverization processing chamber 4a of the soot pulverization processing device 4 flows out through the drain pipe 3A.

  Next, as shown in step 107, for example, after 10 seconds have elapsed from the time when the control panel 11 stops the motor 4B of the soot pulverization processing device 4, the electromagnetic valve 10 is closed and the pulverization processing of the soot pulverization processing device 4 is performed. Water supply to the chamber 4a is stopped. At this time, the water in the pulverization processing chamber 4a of the soot pulverization processing device 4 and the drain pipe 3A communicating with the pulverization processing chamber 4a almost completely flows out to the outside and a small amount of processing object having a relatively high specific gravity. (For example, an egg shell or the like) remains in the crushing chamber 4a or the drain pipe 3A.

  When the solenoid valve 10 is closed, no pressure water is supplied to the water supply passage in the main body. On the other hand, the water in the water supply passage in the main body is supplied from the secondary side flow path b2 to the soot pulverization processing device 4. It tends to flow out toward the drain pipe 3A through the pulverization chamber 4a. Therefore, the valve body 11 falls due to its own weight or negative pressure due to siphon action, and air flows into the main body water supply passage through the air intake 5a, and the negative pressure due to siphon action is destroyed by the inflow, and the main water supply passage or Water inside the secondary side water supply system 7 flows out smoothly into the drain pipe 3A.

  Next, as shown in step 108, the control panel 11 opens the electromagnetic valve 10 again for, for example, 11 seconds or 40 seconds after 11 seconds have elapsed since the electromagnetic valve 10 was closed. As a result, the water in the water supply 6A is supplied to the pulverization processing chamber 4a of the straw pulverization processing device 4 through the vacuum breaker 5 and the like as described above. As a result, a small amount of processing object having a relatively large specific gravity remaining in the pulverization processing chamber 4a or the drain pipe 3A is washed away cleanly.

  The series of operations described above are those during normal use. For example, when an object to be processed is pulverized in the pulverization processing chamber 4a in step 104, the water supply 6A may be in an unintended water cutoff state. The operation at this time is performed as follows.

  Since the control panel 11 holds the electromagnetic valve 10 in an open state, the electromagnetic valve 10 remains open. Therefore, a negative pressure acts on the primary side water supply system 6 by the reverse siphon action in the water supply 6A. Since the negative pressure causes a back flow in the water in the primary water supply system 6, the check valve 9 is instantaneously closed. On the other hand, the water inside the main body water supply passage and the secondary water supply system 7 in a sealed state tends to flow into the drain pipe 3A through the pulverization chamber 4a. By the same action as when the valve is closed, the valve body 11 immediately descends and the air intake 5a is opened, and the air flows into the main body water supply passage through the air intake 5a. The internal negative pressure of the inner water supply passage and the secondary side water supply system 6 is destroyed, and the water inside the main body water supply passage, the primary side water supply system 6 and the secondary side water supply system 6 is smoothly pulverized into the processing chamber 4a. And then flows out to the drain pipe 3A. Therefore, a situation in which the object to be processed flows backward deeply in the secondary side water supply system 7, the main body water supply passage and the primary side water supply system 6 is reliably avoided.
