2. Description of the Related Art As an apparatus for treating garbage discharged in a kitchen or the like, the present applicant has disclosed in Japanese Patent Application Laid-Open No. 10-442, a garbage disposal apparatus for continuously treating garbage by dehydrating, crushing and decomposing microorganisms. Has filed. The garbage disposal process in this case is performed in the following order. First, the garbage thrown in from the inlet is deposited on the draining part, and the garbage is drained.
A gate, which is a blocking member, is disposed below the draining section, and shuts off between the draining section and the crushing section below the gate during draining. This prevents the water mixed in the garbage from flowing through the transfer path that transfers the garbage to the crushing unit, and further flows from the crushing unit to the microbial decomposition unit, and reduces the degradation performance of microorganisms in the microbial decomposition unit. To prevent.

[0003] The cutoff between the draining section and the pulverizing section is specifically performed as follows. That is, the gate is brought into contact with an annular seal member provided above and below the gate to seal it, and the opening and closing port is closed. Next, the gate is rotated to open the opening and closing port, thereby allowing communication between the draining section and the crushing section, sending garbage to the crushing section through the transfer path, and crushing the garbage finely in the crushing section. . Then, the crushed garbage is sent to a microbial decomposition section, where the garbage is decomposed by microorganisms.

[0004]

However, in the above-mentioned prior art, the gate has a spherical shape projecting upward, and when opening and closing the opening and closing opening, the gate is provided between the annular sealing members provided above and below. When it enters, it comes into contact with these seal members and rotates while sliding. The gate slides with the seal member over most of the operating range.

For this reason, the sliding resistance between the gate and the seal member is increased, and the operating force when rotating the gate is increased. In extreme cases, the gate cannot be closed. was there. The present invention has been made in view of the above point, and an object of the present invention is to reduce the operating force of a blocking member and, at the same time, reliably block an opening / closing opening by the blocking member.

The pressing portion 10c is a range other than the angle θ in the entire circumference of the outer peripheral edge of the spherical portion 10a.

The angle θ shown in FIG. 5 corresponds to the angle θ in FIG. Therefore, when the gate 10 is in contact with the seal member 15 in the closed position Y, the range of the angle θ in FIG. 5 of the seal member 15 is pressed by the first pressing portion 10b, and the range other than the angle θ in FIG. Is pressed by the second pressing portion 10c. Note that the angle θ

A pulverizing section 17 for pulverizing garbage is provided downstream of the transfer path 16. The pulverizing unit 17 includes a pulverizing blade 18 and a pulverizing motor 19 for driving the pulverizing blade 18 to rotate. On the left side of the crushing unit 17 in FIG. 1, there is provided a microbial decomposition unit 30 for decomposing the garbage crushed by the crushing unit 17 with microorganisms. A microbial container 31 is provided in the microbial decomposition unit 30. The microbial container 31 contains a microbial carrier carrying aerobic bacteria that can withstand high temperatures.

At the bottom of the microorganism container 31, there is provided a mesh-shaped water passage 32 having water permeability. Decomposed water generated by the decomposition of garbage by the water passage section 32 is discharged to a discharge passage 34 located below. The microorganism container 3 contains the microorganism container 3
A stirring blade 36 is provided to stir the garbage taken into the garbage 1 and the microbial carrier to increase the garbage decomposition efficiency. The stirring blade 36 is driven to rotate by a stirring motor 38 via a belt 37.

Above the microbial decomposition section 30, a temperature control heater 39 for heating the microbial carrier in the microbial container 31 to a predetermined temperature is provided. Then, the heat generated by the temperature control heater 39 is sent to the ventilation duct 33 by the fan 40 to heat the microorganism container 31 from the outer wall. Further, a ventilation pump 41 and a suction pipe 43 having a suction port at a tip thereof are installed above the microbial decomposition unit 30.

A ventilation pipe 42 made of vinyl chloride is connected to a discharge port of the ventilation pump 41. The downstream part of the ventilation pipe 42 is connected to the discharge pipe 35. And, by the ventilation pump 41, the microorganism container 31
The decomposition gas generated when the garbage is decomposed inside is discharged to the discharge pipe 35 through the ventilation pipe 42. This prevents the decomposed gas from leaking outside the garbage disposal apparatus 1, that is, indoors (for example, a kitchen).

The temperature control heater 39 and the ventilation pump 41 are configured to always operate when the garbage disposal device 1 is powered on (the outlet is plugged into the power source). Next, the operation of the garbage processing apparatus 1 based on the above configuration will be described. When the garbage is thrown in from the input port 3 and the garbage accumulates in the draining part 4, the water in the garbage is naturally discharged from the plurality of small holes formed in the draining part 4. The garbage is drained to 20. At this time, the gate 10 is at the closed position Y and shuts off the space between the charging port 3 and the crushing unit 17.

When the user treats the garbage deposited in the draining section 4, first, the gate 10 is turned from the closed position Y to the open position X, and the opening 14 is opened. . Next, the draining part 4 is removed upward, and the garbage in the draining part 4 is sent from the opening and closing port 14 to the crushing part 17 through the transfer path 16. Next, the gate 10 is rotated from the open position X to the closed position Y, and the opening / closing port 14 is closed, and the crushing unit 17 is closed.
By rotating the crushing motor 19 of the
Rotates and crushes the garbage finely. The crushed garbage is transported so as to blow to the left in FIG. 1 and sent into the microorganism container 31 of the microbial decomposition unit 30.

In the microorganism container 31, the stirring motor 38 is driven to rotate the stirring blade 36, and the garbage sent into the microorganism container 31 and the microorganism carrier in the microorganism container 31 are stirred. Thereby, the garbage is decomposed by the microorganisms in the microorganism carrier into decomposed gas and decomposed water. The outside air necessary for decomposing the garbage is sucked into the microorganism container 31 from the suction pipe 43 by the ventilation pump 41.

Microorganism container 31 generated by decomposition of garbage
The decomposed gas inside is discharged to the discharge pipe 35 by the ventilation pump 41, and the decomposed water is discharged from the discharge passage 34 to the discharge pipe 35. In addition, when not using the garbage processing apparatus 1,
The waste water is discharged from the discharge passage 20 located on the right side in FIG.
Sent to 5.

Next, the opening / closing operation of the opening / closing port 14 by the gate 10 will be described. When the gate 10 is at the open position X, the gate 10 is housed in the discharge path 20. At this time, there is communication between the upstream input port 3 in the garbage input direction A and the downstream crushing unit 17. Next, the gate 10 rotates from the open position X to the closed position Y. The gate 10 is rotated by a rotating means such as an electric motor as an electric driving means or a stepping force of a user himself.

In the closed position Y, the gate 10 comes into contact with the sealing member 15 and presses it to seal the opening / closing opening. At this time, the gate 1 is located between the charging port 3 and the crushing unit 17.
Blocked by 0. Next, the gate 10 rotates from the closed position Y to the open position X. When the gate 10 reaches the open position X, it is stored in the discharge path 20 again. In the present embodiment, at the closed position Y, the gate 10 presses the seal member 15 from above by the second pressing portion 10c, and presses the seal member 15 from the lateral direction by the first pressing portion 10b.

When the gate 10 rotates from the closed position Y to the open position X, the first and second pressing portions 10b, 1b
As soon as the gate 10 starts rotating, the gate 0c separates from the seal member 15 and rotates to the open position without being in contact with the seal member 15. When the gate 10 is in the open position X
When the first and second pressing portions 10b and 10c rotate in a state where they are not in contact with the seal member 15, and immediately before the gate 10 stops at the closed position Y,
It comes into contact with the seal member 15 and presses the seal member 15 from the lateral direction.

For this reason, compared to the prior art, the gate 1
In the operating range of 0, the sliding range between the gate 10 and the seal member 15 is small, and the sliding resistance is significantly reduced. Therefore, the operation force of the gate 10 can be reduced. Further, since the sliding resistance of the gate 10 is reduced, the gate 10 is easily rotated, and the operation of contacting the gate 10 with the seal member 15 and pressing the same is facilitated. Therefore, when the opening / closing opening 14 can be reliably shut off by the gate 10, if the angle θ shown in FIG. 4 is smaller than 150 °, the ratio of the first pressing portion 10b to the outer peripheral edge of the gate 10 becomes small, and the second The ratio of the pressing portion 10c increases. In this case, when the gate 10 rotates, the sliding portion between the gate 10 and the seal member 15 increases, so it is difficult to achieve the purpose of reducing the sliding resistance and reducing the operating force of the gate. is there. If the angle θ is greater than 180 °, it is difficult to shut off the opening 14 by the gate 10 when the gate 10 rotates from the open position X to the closed position Y. Therefore, the angle θ is 15
It is preferably between 0 ° and 180 °.

Further, in this embodiment, the gate 10 and the seal member 15 are in contact with each other in an inclined state such that the side closer to the open position X is lower and the side farther from the open position X is upper. By doing so, the movement of the gate 10 away from the seal member 15 when the gate 10 starts rotating from the closed position Y to the open position X can be further accelerated.

As a result, the gate 10 is connected to the sealing member 15
The sliding range of the operating range of the gate 10 can be further reduced as compared with the case where the gate 10 is contacted at a horizontal position. Next, the gate 10 is opened and closed at the closed position Y.
The state of contact between the gate 10 and the seal member 15 when the shutter is blocked will be described with reference to FIG.

FIG. 6 shows the sealing member 1 in the direction of arrow B in FIG.
FIG. 5 is an enlarged view of an angle θ of FIG. 5 and a boundary portion of a range other than the angle θ. FIG. 6A in FIG. 6 shows the seal member 15 when the gate 10 is at the open position X, that is, the seal member 15 in a state where the gate 10 is not in contact. FIG.
(B) shows the seal member 15 when the gate 10 is at the closed position Y, that is, the seal member 15 pressed against the gate 10.

In FIG. 6B, reference numeral 15- denotes a surface pressed by the first pressing portion 10b of the gate 10 in a direction perpendicular to the garbage input direction A, that is, a lateral direction. The second pressing portion 10c is a surface pressed in a direction parallel to the garbage input direction A, that is, from above. Further, as a result of being pressed by the first pressing portion 10b, the seal member 10 is compressed by a width e in a direction orthogonal to the direction of inputting garbage A, and is pressed by the second pressing portion 10c, so that the garbage input direction is obtained. It is compressed by a width f in a direction parallel to A.

The angle θ of the sealing member 15 shown in FIG.
In the range, the upper surface of the seal member 15 in the range of the angle θ is not necessarily required because only the side portion contacts the first pressing portion 10b. In the range other than the angle θ of the seal member 15, the side surface of the seal member 15 in a range other than the angle θ is not necessarily required because only the upper surface contacts the second pressing portion 10 c. (Second Embodiment) Next, a second embodiment of the present invention will be described with reference to FIGS.

In the second embodiment, a backflow prevention device 44 is provided in the suction pipe 43 in the garbage processing apparatus 1 of the first embodiment shown in FIG. Further, the same functions as those in the first embodiment are denoted by the same reference numerals. In the second embodiment, as in the first embodiment, the ventilation pump 41 is always operating when the garbage disposal device 1 is powered on (the outlet is plugged into the power source). When the ventilation pump 41 is operated and air is normally sucked, the air in the microorganism container 31 does not leak to the outside.

However, if the ventilation pump 41 is stopped due to a power failure or the like and no air is being taken, the microorganism container 31
There is a problem that the air inside leaks outside from the suction pipe 43 and the odor leaks out of the garbage disposal apparatus 1. Therefore, the second
In the garbage processing apparatus 1 according to the embodiment, a backflow prevention device 44 composed of an umbrella-shaped rubber valve shown in FIG.

In the second embodiment, the backflow prevention device 4
Although an umbrella-type rubber valve is used as 4, an electromagnetic valve (an electromagnetic check valve) that seals the suction pipe 43 when the power is turned off can be used instead of the umbrella-type rubber valve. (Third Embodiment) Next, a third embodiment of the present invention will be described with reference to FIGS.

The garbage processing apparatus 1 according to the third embodiment is provided with seal portions 50 shown in FIG. 9 at four places (50a to 50d) shown in FIG. This seal portion 50
The groove-side member 51, the protrusion-side member 52, and the filler 53 are formed. The groove side member 51 and the protrusion side member 52 are formed of a resin material such as polypropylene containing talc 20%. The width of the opening of the groove-side member 51 is larger than the width of the bottom, and the filling space of the filler 53 formed by the groove-side member 51 and the protrusion-side member 52 extends from the bottom of the groove-side member 51 toward the opening. It has a narrow structure. The filling space is filled with a filling material 53 such as a hot butyl sealant.

As a similar seal structure in the prior art, there is a seal structure in which a filler 53 filled in a groove-side member 51 having a rectangular cross section shown in FIG. However, according to this conventional technique, when the filler 53 is heated to reduce the viscosity, and is discharged from the nozzle 54 to fill the groove-side member 51, the wall surface of the filler 53 before the filler 53 reaches the bottom surface of the groove-side member 51. When you touch
As shown in FIGS. 11B and 11C, air is easily trapped in the corners of the bottom surface. Therefore, the filling material 53
Of the adhesive may decrease.

Further, if an elongated nozzle 54 whose tip reaches near the bottom of the groove side member 51 is used so as not to come into contact with the wall surface, heat radiation from the nozzle 54 is large, and the viscosity of the filler 53 in the nozzle 54 during the stop of discharge is increased. Rises. For this reason, since a stable discharge amount cannot be obtained, there are problems such as a material loss caused by throwing out the filler 53 and a heater for heating the nozzle 54 to be installed.

According to the seal portion 50 of the third embodiment, since the width of the opening of the groove-side member 51 is larger than the width of the bottom portion, as shown in FIG. 10 reaches near the bottom surface of the groove side member 51, and FIG.
As shown in (b), it is possible to prevent air from being trapped when the filler 53 is filled. Further, since the filling space of the filling material 53 is narrowed from the bottom of the groove side member 51 toward the opening, when the filling material 53 is crushed by the projection side member 52 as shown in FIG. Stress is generated on the contact surface between the groove-side member 51 and the protrusion-side member 52 and the filler 53, and a good adhesive strength can be obtained.

The seal portion 50 is used as a seal structure for preventing the odor inside the garbage disposal device 1 from leaking to the outside, but prevents water from entering from outside into the housing containing the electronic circuit. It can also be used as a seal structure for sealing. (Fourth Embodiment) Next, a fourth embodiment will be described.

In the second embodiment, the air in the microorganism container 31 leaks from the suction pipe 43 to the outside, and the garbage disposal device 1
An umbrella-type rubber valve (backflow prevention device) 44 is provided in the suction pipe 43 in order to prevent a problem that odor leaks outside. When the ventilation pump 41 is operating, the umbrella-shaped rubber valve 44 is opened by a negative pressure generated in the microbial container 31 to allow the outside air to be sucked into the microbial container 31.
When the ventilation pump 41 is not operating, the valve is closed by the elastic force of rubber so that the air in the microorganism container 31 is not leaked to the outside.

However, in such a configuration, it is difficult to lower the opening pressure of the valve corresponding to the elastic force of the rubber, and the negative pressure level in the microorganism container 31 becomes too high.
The valve may be damaged. Therefore, in the fourth embodiment, a backflow prevention device 44 provided in the suction pipe 43 is shown in FIG.
The electromagnetic check valve shown in Fig. 1 is used.

Hereinafter, the electromagnetic check valve 44 will be described with reference to FIG.
Will be described. When the electromagnetic check valve 44 is not energized, the valve body 44c is pressed against the valve seat 44d to close the valve. When the electromagnetic check valve 44 is energized, the coil 4
4c generates an electromagnetic force, and the valve body 44a is pulled up in FIG. Then, the valve body 44a is separated from the valve seat 44b and opened, so that the inside of the microorganism container 31 is communicated with the outside through the suction pipe 43. Thereby, the microorganism container 3
1 allows the outside air to be sucked into the inside.

On the other hand, when the power supply to the electromagnetic check valve 44 is interrupted due to power-off or power failure, the valve body 44a is pressed against the valve seat 44b by the spring force of the spring 44d to close the valve. Thereby, the inside of the microorganism container 31 and the outside are shut off. As described above, since the electromagnetic check valve 44 opens the valve by energizing and connects the inside of the microorganism container 31 to the outside irrespective of the negative pressure level in the microorganism container 31, the electromagnetic check valve 44 Can be kept low. Therefore, it is possible to prevent the valve from being damaged due to the negative pressure level in the microorganism container 31 becoming too high. When the power is not supplied to the garbage disposal apparatus 1, the power supply to the electromagnetic check valve 44 is cut off, the suction pipe 43 is surely cut off, and the air (odor) in the microorganism container 31 is shut off. Can be prevented from leaking to the outside.
