  Conventionally, it is provided in the lower part of the sink and in the cabinet, and the garbage thrown in from the inlet is crushed in the crushing chamber with water by a fixed blade and a rotating blade, and the crushed material is provided through the crushing chamber. Disposers are known which are discharged from the discharge holes and discharged from the discharge port of the apparatus main body to the drain pipe.

For example, the following Patent Document 1, Patent Document 2, Patent Document 3, and Patent Document 4 disclose such a disposer.
7 and 8 specifically show an example of this type of disposer (the one shown is disclosed in Patent Document 1).
In FIG. 7, reference numeral 200 denotes a sink, 202 denotes a cabinet in the sink 200, 204 denotes a sink, and 206 denotes a counter. A sink faucet 208 is installed on the counter 206.

A disposer 210 is provided below the sink 204 and in the cabinet 202 in a state of being suspended by the sink 204.
Reference numeral 212 denotes an apparatus main body of the disposer 210, which has an input port 214 that opens at the bottom of the sink at the upper end and a crushing chamber 216 as shown in FIG. 8.

The crushing chamber 216 is provided with a cylindrical fixed blade 218 and a rotary blade 220.
A number of crushing holes 222 are formed in the fixed blade 218 along the peripheral wall. Here, the crushing hole 222 constitutes a discharge hole for discharging the crushed material from the crushing chamber 216 to the outside, and at the same time, its periphery constitutes a crushing blade.
On the other hand, a hammer 224 is provided on the upper surface of the rotary blade 220 in a freely rotating state around an axis at a position eccentric from the rotational axis.
The rotary blade 220 is also provided with a crushing hole 226.

A motor 227 is directly connected to the rotary blade 220, and the rotary blade 220 is rotationally driven by the motor 227.
The apparatus main body 212 is provided with a discharge port for discharging the crushed material together with the waste water, and a drain pipe 228 for discharging the crushed material of the garbage together with the waste water extends from the discharge port.
The drain pipe 228 is provided with a trap 230 at a predetermined position as shown in FIG.

In the disposer 210, the rotary blade 220 is driven to rotate by the motor 227, and the garbage put into the crushing chamber 216 is crushed or ground by the rotary blade 220 and the fixed blade 218 under water supply and crushed.
The crushed garbage is discharged together with water from the many crushing holes 222 and 226 together with drainage, then flows into the drainage pipe 228 from the discharge port, and is discharged to the outside through the drainage pipe 228.

In this type of disposer, improvement of crushability is always required, but in the past, the focus has been on improving the blade shape, which improves crushability by improving drainage. No particular proposal has been made for.
That is, in a disposer that crushes garbage under the supply of a large amount of water, the quality of drainage is not only good or bad in drainage but also affects the quality of crushability.

  In this type of disposer, the air between the crushing chamber 216 and the trap portion 230, strictly speaking, the discharge port if the discharge holes (in the above, crushing holes 222, 226) of the crushing chamber 216 are not blocked by water. The air in the drainage pipe 228 between the trap portion 230 and the trap portion 230 can escape into the crushing chamber 216 through the discharge hole when the drainage flows into the drainage pipe 228. At this time, the flow of drainage is performed to some extent smoothly.

However, when a large amount of water flows into the crushing chamber 216, if the discharge hole of the crushing chamber 216 is blocked by the water, the air in the drain pipe between the discharge port and the trap portion has no escape space. And get trapped there.
Then, the trapped air becomes an obstacle, and the drainage does not smoothly flow from the crushing chamber 216 into the drain pipe 228, and the drainage performance deteriorates.

  At this time, the crushing chamber 216 is filled with a large amount of water, and the garbage or crushed material floats in the water. It will not be sufficiently crushed by the crushing blade, and crushing performance will deteriorate.

The present invention has been made to solve such problems.
In addition, as technologies that seem to be similar to the present invention, there are those disclosed in the following Patent Literature 5, Patent Literature 6, and Patent Literature 7, of which those disclosed in Patent Literature 5 and Patent Literature 7 are used for drainage. The air trapped in the drain pipe cannot escape and is different from the present invention.

  Moreover, although what is disclosed in Patent Document 6 seems to allow air trapped in the drain pipe upstream of the trap portion to escape into the sink, the one disclosed in Patent Document 6 has a dedicated overflow port. There is a difficulty that can only be applied to those with special sinks.

JP 2002-45722 A JP 2002-248368 A JP 2003-2111016 A JP 2003-305379 A JP 2002-172344 A JP 2001-276642 A JP 2000-84430 A

  With this background, the present invention can ensure smooth drainage even when the discharge hole in the crushing chamber is clogged with water, thereby realizing good drainage performance and crushing performance. The purpose of this is to provide a disposer that does not require processing of sinks, counters, etc.

  Thus, according to the first aspect of the present invention, the garbage disposed at the lower part of the sink and in the cabinet is crushed under the water supply by the fixed blade and the rotary blade in the crushing chamber, and the crushed material is crushed. In the disposer that discharges from the discharge hole that penetrates the chamber and discharges from the discharge port of the apparatus main body to the drain pipe, the ventilation pipe is raised from the portion between the trap portion and the discharge port in the drain pipe, The vent pipe includes a vent opening that opens in the cabinet, and air between the trap portion in the drain pipe and the discharge port is allowed to escape from the vent hole.

  According to a second aspect of the present invention, in the first aspect, the vent pipe includes a float valve that moves up and down in conjunction with a water level to allow only air to escape from the vent, while preventing overflow of drainage from the vent. It is provided.

  According to a third aspect of the present invention, the garbage thrown in from the charging port is crushed in the crushing chamber by the fixed blade and the rotating blade under water supply, and the crushed material is discharged from the discharge hole penetrating the crushing chamber. In the disposer configured to discharge from the discharge port to the drain pipe, air between the trap part and the discharge port in the drain pipe is discharged from a portion between the trap part and the discharge port in the drain pipe. The vent pipe to be escaped is extended, and the vent at the tip thereof is connected to the crushing chamber.

  According to a fourth aspect of the present invention, in the third aspect, the branch pipe is extended from the vent pipe, and the opening at the tip of the branch pipe is connected to the crushing chamber at a position below the vent hole. The pipe is provided with an on-off valve.

  According to a fifth aspect of the present invention, in the fourth aspect of the present invention, the opening at the tip of the branch pipe is connected to the crushing chamber at an upper and lower intermediate position of the fixed blade in the crushing chamber.

  According to a seventh aspect of the present invention, in any one of the third to sixth aspects, the crushing chamber includes a reverse-tapered anti-jumping shape portion that prevents the crushed material from jumping up toward the vent hole. It is characterized by that.

  According to an eighth aspect of the present invention, in any one of the third to seventh aspects, the vent includes a filter that prevents the crushed material from entering the vent pipe.

Effects and effects of the invention

As described above, according to the first aspect of the present invention, there is provided a vent opening that opens in the cabinet, and the vent pipe for releasing the air in the drain pipe between the trap section and the discharge opening is provided between the trap section and the discharge outlet of the drain pipe. According to the present invention, even if the discharge hole of the crushing chamber is clogged with a large amount of water, the inside of the drain pipe between the trap portion and the discharge port, that is, the crushing chamber, Air does not lose its escape and become trapped, and can escape well through the vent of the vent pipe.
Therefore, according to the present invention, it is possible to solve the problem that the air trapped between the trap part and the discharge port becomes an obstacle and the drainage performance is impaired, and the crushing chamber is filled with a large amount of water. However, smooth drainage can be secured.

Moreover, since drainage can be performed smoothly, excess water in the crushing chamber can be quickly discharged, and the garbage can be crushed well.
In other words, it is possible to solve the problem that the garbage is not in good contact with the crushing blade due to the state that the garbage or the middle of the crushing is floating in a large amount of water, and the crushing performance is thereby lowered. Can be efficiently crushed.

The disposer of the present invention is characterized in that a vent pipe raised from a drain pipe is housed in a space in the cabinet, and air in the drain pipe is released into the cabinet.
Therefore, in the present invention, there is no need to connect the vent pipe extending from the drain pipe with a counter, a sink, or the like, and the venting mechanism is completed by the disposer itself. Do not need.

In this case, the vent pipe can be provided with a float valve that opens and closes the vent in conjunction with the water level (claim 2).
In this way, air in the drain pipe can be escaped from the vent hole, while overflow of drainage from the vent hole can be prevented, and effectively preventing the overflow water from getting wet in the cabinet. it can.

Next, a third aspect of the present invention is such that a vent at the tip of a vent pipe extended from the drain pipe is connected to the crushing chamber in order to escape air in the drain pipe.
If it does in this way, since there is no possibility that the waste_water | drain in a drain pipe leaks outside, the advantage which does not need to provide the above vent valves is acquired.

  In addition, when the vent at the tip of the vent pipe is connected to the crushing chamber in this way, when a large amount of water is supplied to the crushing chamber, this vent pipe works as an overflow pipe to quickly remove excess water in the crushing chamber. It can be drained into the drain and removed from the crushing chamber. Thereby, the crushing efficiency in the crushing chamber can be increased.

Next, when the vent hole at the tip of the vent pipe is connected to the crushing chamber in this way, the branch pipe extends from the vent pipe so that the opening at the tip is positioned below the vent hole. In addition to being connected to the crushing chamber, the branch pipe is provided with an on-off valve.
In this fourth aspect, the water level in the crushing chamber can be lowered to the position of the opening at the tip of the branch pipe by opening the on-off valve, and the water level in the crushing chamber can be lowered at the connection port at the tip of the vent pipe by closing the on-off valve. Can be raised to position.

According to the fourth aspect, the water level is lowered or raised according to the amount of garbage, specific gravity and the like in the crushing chamber, so that crushing can be performed more efficiently.
For example, if the amount of garbage is small or the specific gravity is light, crushing can be performed more efficiently by lowering the water level, while the amount of garbage is high or the specific gravity is heavy. In this case, crushing can be performed more efficiently by increasing the water level.

If the amount of garbage is small or the specific gravity is light, if the water level in the crushing chamber is high, that is, if the amount of water is large, they will float in a large amount of water, and crushing with a crushing blade will be performed efficiently. I will not be broken.
Therefore, in this case, lowering the water level allows the garbage to be collected in a small amount of water, and by crushing it with a crushing blade under the aggregated state, efficient crushing is performed. Can do it.

On the other hand, when the amount of garbage is large or the specific gravity is heavy, it is better to crush using as many crushing blades as possible. Therefore, in this claim 4, in such a case, the water level is raised to raise the garbage. Try to contact as many crushing blades as possible.
This also enables efficient crushing.

  In this case, it is preferable that the opening at the tip of the branch pipe is connected to the crushing chamber at an intermediate position between the fixed blades in the crushing chamber (Claim 5).

The sixth aspect of the present invention further includes a control unit that controls opening / closing of the on-off valve in accordance with a load applied to a motor that rotationally drives the rotary blade.
If such a control unit is provided so as to perform opening / closing control of the on-off valve, the crushing of the garbage in the crushing chamber can be automatically maintained with high efficiency.

Specifically, when the amount of garbage is small or the specific gravity is light, the load on the motor is small. Therefore, the control unit can open the on-off valve to lower the water level, thereby reducing the amount of garbage or reducing the specific gravity. Garbage can be crushed efficiently.
On the other hand, when the load applied to the motor is large, the amount of garbage is large or the specific gravity is heavy. In this case, the water level is increased by closing the on-off valve, thereby increasing the amount or specific gravity. Heavy garbage can be crushed with high efficiency.

According to the seventh aspect of the present invention, in order to prevent the crushed material in the crushing chamber from jumping up and entering into the vent pipe as the vent of the vent pipe is connected to the crushing chamber, This is provided in the crushing chamber.
If it does in this way, it will become possible to prevent effectively that a crushed material jumps up at the time of crushing garbage, and enters into a vent pipe from a vent.

  On the other hand, claim 8 is provided with a filter at the vent, and even in this case, it is possible to effectively prevent the crushed material from entering the vent pipe.

Next, embodiments of the present invention will be described in detail with reference to the drawings.
In FIG. 1, 10 is a sink, 12 is a cabinet in the sink 10, 14 is a sink, 16 is a counter, and a sink faucet 18 is installed on the counter 16.

Reference numeral 20 denotes a disposer installed in the lower part of the sink 14 and in the cabinet 12, and 22 denotes a main body of the apparatus.
As shown in FIG. 2, the apparatus main body 22 has a crushing chamber 24, and the crushing chamber 24 is provided with a fixed blade 26 and a rotary blade 28 having a cylindrical shape.

A hammer 30 is provided on the upper surface of the rotary blade 28 in a freely rotating state around an axis at a position eccentric from the rotational axis.
On the other hand, the fixed blade 26 is provided with a number of crushing holes 32A formed of circular holes along the circumferential surface thereof. In the lower stage, a plurality of crushing holes 32B each having a long hole shape are provided along the circumferential surface.
That is, here, two types of crushing holes 32A and 32B of different types are formed in the upper and lower stages of the fixed blade 26, respectively.

These crushing holes 32A and 32B constitute crushing material discharge holes, and the peripheral edges thereof constitute crushing blades.
A driving motor 34 is directly connected to the rotary blade 28, and the rotary blade 28 is rotationally driven by the motor 34.

A discharge port 36 of the apparatus main body 22 has a drain pipe 38 extending from the discharge port 36. The drain pipe 38 is provided with a trap portion 40.
In this embodiment, the crushed food waste crushed in the crushing chamber 24 is discharged into the drain pipe 38 from the discharge port 36 together with the drainage, and is further discharged to the outside through the drain pipe 38.

A vent pipe 42 rises upward from a portion of the drain pipe 38 between the trap portion 40 and the discharge port 36.
The vent pipe 42 is provided with a vent hole 44 opened in the cabinet 12 at the upper end thereof, and the vent hole 44 is opened and closed by a float valve 46 that moves up and down in conjunction with the water level in the vent pipe 42. It has become.
In FIG. 2, reference numeral 48 denotes a cover.

The float valve 46 operates as follows.
That is, as shown in FIG. 3 (A), when drainage does not flow into the vent pipe 42, the float valve 46 is in the lowered position and the vent port 44 is open. The air inside can escape well through the vent 44 to the outside, i.e. into the cabinet 12.

On the other hand, as shown in (B), when drainage flows into the vent pipe 42 and the water level rises, the float valve 46 rises in conjunction with the rise of the water level and closes the vent hole 44.
Accordingly, the waste water flowing into the vent pipe 42 does not overflow into the cabinet 12 through the vent hole 44.

In the disposer 20 of this embodiment, the garbage thrown into the crushing chamber 24 from the charging port opened at the bottom of the sink is crushed by the rotary blade 28 and the fixed blade 26 that are rotationally driven by the motor 34 under water supply. The
The crushed material is discharged out of the crushing chamber 24 through the crushing holes 32 </ b> A and 32 </ b> B together with the drainage, further flows into the drainage pipe 38 from the discharge port 36, and is discharged outside through the drainage pipe 38.

  At this time, even if the crushing holes 32A and 32B may be clogged with a large amount of water, in this embodiment, the air loses escape space in the drain pipe 38 between the trap portion 40 and the discharge port 36, that is, the crushing chamber 24. The air between the trap portion 40 and the discharge port 36 can escape to the outside through the vent hole 44 of the vent pipe 42 without being trapped.

Therefore, according to the present embodiment, air is confined between the trap portion 40 and the discharge port 36 and the drainage performance is not impaired, and the crushing chamber 24 is filled with a large amount of water. Even if it is, smooth drainage to the drain pipe 38 can be ensured.
Moreover, since drainage can be performed smoothly, excess water in the crushing chamber 24 can be quickly discharged, and the garbage can be crushed well.

  In the present embodiment, the vent pipe 42 raised from the drain pipe 38 is housed in the space in the cabinet 12 and the air in the drain pipe 38 is allowed to escape into the cabinet 12, so that the vent pipe 42 extends from the drain pipe 38. It is not necessary to connect the vent pipe 42 to the counter 16, the sink 14, or the like, and the mechanism for ventilation can be completed by the disposer 20 itself.

  In addition, the vent pipe 42 is provided with a float valve 46 that opens and closes the vent hole 44 in conjunction with the water level, so that air in the drain pipe 38 can escape from the vent hole 44, while preventing overflow of drainage. As a result, the problem that the overflow water wets the cabinet 12 does not occur.

FIG. 4 shows another embodiment.
As shown in the figure, in this embodiment, the vent pipe 42 is bent halfway, and the vent hole 44 at the tip thereof is connected to the upper portion of the crushing chamber 24. Specifically, it is connected to the crushing chamber 24 at a position above the fixed blade 26.
In this way, air in the drain pipe 38 can be released, and in this embodiment, there is no possibility that drainage in the drain pipe 38 leaks to the outside. Therefore, the float valve 46 as described above is provided. The advantage which is not necessary is obtained.

  Further, when the vent 44 at the tip of the vent pipe 42 is connected to the crushing chamber 24 in this way, when a large amount of water is supplied into the crushing chamber 24, the vent pipe 42 functions as an overflow pipe. The excess water can be quickly removed into the drain pipe 38, and the crushing efficiency in the crushing chamber 24 can be increased.

FIG. 5 shows still another embodiment of the present invention.
In this embodiment, the branch pipe 50 is branched from the vent pipe 42 in the embodiment of FIG. 4, and the opening 52 at the tip of the branch pipe 50 is at a position below the vent hole 44. This is an example in which an open / close valve (electromagnetic valve) 54 is provided on the branch pipe 50 connected to the crushing chamber 24 at a position between the upper crushing blade 32A and the lower crushing blade 32B.

In this embodiment, a control unit 56 that controls the opening / closing of the opening / closing valve 54 according to the load applied to the motor 34 is also provided.
Here, the control unit 56 detects the current value of the motor 34 at the time of garbage crushing, detects the load applied to the motor 34, and if the load is small, opens the on-off valve 54 to open the branch pipe 50. .

At this time, the water level in the crushing chamber 24 is lower than that of the opening 52 of the branch pipe 50. Therefore, the garbage put into the crushing chamber 24 is crushed mainly by the lower crushing holes 32B under a small amount of water.
In other words, garbage or crushed materials are concentrated in low-level water and are efficiently crushed by the crushing holes 32B in a narrow space.

On the other hand, when the load applied to the motor 34 is large, that is, when the amount of garbage is large or the specific gravity is large, the control unit 56 closes the open / close valve 54 and shuts off the branch pipe 50.
At this time, the maximum water level in the crushing chamber 24 becomes the height up to the vent hole 44. Therefore, garbage and those in the middle of crushing are formed by both the lower crushing hole 32B and the upper crushing hole 32A, that is, in the crushing chamber 24. The whole crushing holes 32B and 32A are efficiently crushed.

FIG. 6 shows another embodiment of the present invention.
In this embodiment, the crushing chamber 24 is provided with a reverse-tapered anti-jumping shape portion 58, and further, the vent 44 is prevented from entering crushed material into the vent pipe 42, allowing only water and air to pass through. This is an example in which a filter 60 is provided.
Here, the filter 60 is provided with a round hole with a diameter of 0.5 to 3 mm or a long hole with a width of 0.5 to 3 mm.

By doing in this way, it becomes possible to effectively prevent the crushed material from jumping upward and entering the vent pipe 42 from the vent 44 when the garbage is crushed.
Further, by providing the filter 60, it becomes possible to effectively prevent the crushed material from entering the ventilation pipe.

  Although the embodiments of the present invention have been described in detail above, these are merely examples, and the present invention can be configured in various modifications without departing from the spirit of the present invention.
