Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a garbage processing apparatus for processing garbage discharged from a kitchen or the like.

[0002]

2. Description of the Related Art Conventionally, there is a so-called kitchen built-in type garbage disposal apparatus which is installed under a kitchen sink to introduce garbage from a drain port of the sink. This type of garbage disposer is located below the drain of the kitchen sink,
There is a known garbage processing tank and a transfer path for transferring garbage to the garbage processing tank, and an opening / closing gate for opening and closing the input port above the garbage input port at the upper end of the transfer path. ing.

[0003] In addition, a ventilation fan as ventilation means and an odor component are removed from the discharged air in an exhaust passage which is a path for discharging air from the garbage processing tank in order to ventilate the garbage processing tank. Equipped with a deodorizer, which is a deodorizing means for the purpose.

When a user disposes of garbage, the user operates an opening / closing gate to open an input port, and the garbage can be sent from the input port to a garbage processing tank through a transfer path. I have.

[0005]

However, in the above-mentioned garbage disposal apparatus, if a ventilation fan having an appropriate capacity in consideration of the ventilation volume in the garbage decomposition tank is provided and the ventilation fan is operated to perform ventilation. Even when the opening / closing gate is operated to open the inlet, it is difficult to increase the amount of exhaust air due to the pressure loss caused by the deodorizer provided in the exhaust passage.

When the exhaust air volume cannot be increased in this way, the flow rate of the air flowing from the input port toward the garbage decomposition tank at the time of opening the input port is small (the flow velocity is low). There is a problem that the odor in the decomposition layer leaks. To cope with this problem, a ventilation fan having a large maximum ventilation capacity can be provided, but there is a problem that the ventilation fan becomes large.

[0007] The present invention has been made in view of the above points, and even in a garbage disposal apparatus having a deodorizing means that causes a pressure loss in the exhaust passage, the garbage can be introduced without increasing the size of the ventilation means. It is an object of the present invention to provide a garbage disposal device that can prevent an odor from leaking from a charging port at times.

[0008]

To achieve the above object, according to the first aspect of the present invention, an input port (7) for inputting garbage and a gate (8) capable of opening and closing the input port (7). And a garbage processing tank (2) for treating the garbage input from the input port (7) and discharging the gas in the garbage processing tank (2). An exhaust passage (B), a ventilation means (63) provided in the exhaust passage (B) for ventilating the inside of the garbage treatment tank (2), and a deodorizing exhaust gas provided in the exhaust passage (B). In a garbage disposal apparatus provided with a deodorizing means (61), a bypass passage (D) for bypassing the deodorizing means (61) and an opening and closing means (65) for opening and closing the bypass passage (D) are provided in the exhaust passage (B). When the gate (8) closes the input port (7), the opening / closing means (65) is provided. Close to control in this way,
When the gate (8) has the opening (7) open, a control means (22) for controlling the opening and closing means (65) to open is provided.

According to this, when the input port (7) is opened for the input of garbage, the garbage disposal tank is opened from the bypass passage (D) which opens the opening / closing means (65) and bypasses the deodorizing means (61). The gas in (2) can be exhausted.
Therefore, the flow rate of the air flowing from the inlet (7) toward the garbage disposal tank (2) can be increased because the deodorizing means (61) is less susceptible to the pressure loss.
In this way, it is possible to prevent the odor from leaking from the input port (7) at the time of inputting the garbage without using a large-sized ventilation means having a large maximum ventilation capacity.

The invention described in claim 2 solves the following problem.

Conventionally, in a general garbage processing apparatus,
The temperature in the garbage processing tank is higher than the outside temperature due to the decomposition or drying of the garbage, and the water generated due to the decomposition or drying of the garbage is steam.
Then, among the parts that communicate with the garbage processing tank, the part of the garbage processing tank that has a lower temperature than the garbage processing tank is likely to invade water vapor in the garbage processing tank and form dew to form dew.

[0012] There is a problem that the dew water is generated and accumulated in a ventilation path such as the bypass passage according to the first aspect of the present invention.

On the other hand, in the invention according to claim 2,
The control means (22) is characterized in that when the gate (8) closes the input port (7), the opening / closing means (65) is controlled to be opened at predetermined time intervals.

According to this, the gas can be flowed into the bypass passage (D) periodically. The upstream side of the opening / closing means (65) of the bypass passage (D) communicates with the garbage processing tank (2), and when the temperature is lower than the inside of the garbage processing tank (2), the opening / closing means of the bypass passage (D) ( 65) Condensed water is generated in the passage on the more upstream side, but due to the gas flowing periodically in the bypass passage (D), the condensed water is discharged before staying in a large amount. Therefore, it is possible to prevent the dew water from hindering the ventilation of the bypass passage (D).

According to the third aspect of the present invention, the bypass passage (D) has a water trap portion (D21) downstream of the opening / closing means (65), and the opening / closing means (65) of the bypass passage (D). ) It is characterized in that the water in the water trap part (D21) is dried by ventilating further downstream.

According to this, the dew water can be retained in the water trap section (D21) provided downstream of the opening / closing means (65) of the bypass passage (D) and dried by ventilation. Therefore, the condensed water is not discharged in a water state downstream of the bypass passage (D), but is discharged as steam. In this way, it is possible to prevent the condensed water from adhering to the components downstream of the bypass passage (D).

According to the invention described in claim 4, the opening (65) of the bypass passage (D) is located on the upstream side (D10) of the opening / closing means (65).
1) is characterized in that water condensed inside is drained to the upstream side of the bypass passage (D).

According to this, the upstream side (D1) of the opening / closing means (65) of the bypass passage (D) communicates with the garbage disposal tank (2), and has a lower temperature than the inside of the garbage disposal tank (2). If so, dew condensation water is generated in the passage upstream of the opening / closing means (65) of the bypass passage (D), but the generated dew condensation water can be drained to the upstream side of the bypass passage (D). Therefore, a large amount of dew water does not stay in the bypass passage (D). In this way, it is possible to prevent the condensed water from hindering the ventilation of the bypass passage (D).

According to the fifth aspect of the present invention, there is provided a gate opening / closing detector (20) for detecting opening / closing of a gate (8);
An electromagnetic valve (65) is provided as the opening / closing means (65), and the control means (22) is configured to control opening / closing of the electromagnetic valve (65) according to a detection signal of the gate opening / closing detector (20). And

According to this, when the gate (8) is switched from the closed state to the open state, the electromagnetic valve (65) provided in the bypass passage (D) is activated by the detection signal from the gate open / close detector (20). Open quickly. Meanwhile, the gate (8)
When switching from the open state to the closed state, the electromagnetic valve (65) provided in the bypass passage (D) is quickly closed by a detection signal from the gate opening / closing detector (20), so that the garbage can be inserted. Odor can be reliably prevented from leaking from the mouth (7).

In the invention according to claim 6, the ventilation means (63) is an electric fan (63).

When the electric fan (63) is used for the ventilation means (63) as described above, it is easy to secure the flow rate if the pressure loss in the exhaust passage (B) is small, but the flow rate is reduced if the pressure loss is large. Therefore, the effect of reducing the influence of the pressure loss by the deodorizer (61) by the configuration of the present invention is extremely large.

Further, the invention according to claim 7 is characterized in that the exhaust passage (B) is configured to discharge gas in the garbage disposal tank (2) to the outside.

According to this, when the input port (7) is opened for the input of garbage, the garbage disposal tank is opened from the bypass passage (D) which opens the opening / closing means (65) and bypasses the deodorizing means (61). (2) Since the gas inside is exhausted, the odor leaks from the outlet of the exhaust passage (B), but since it can be exhausted outdoors, the user's discomfort can be prevented.

In the invention according to claim 8, the garbage treatment tank (2) is characterized in that the inputted garbage is decomposed by microorganisms.

As described above, the garbage disposal apparatus (1) using microorganisms can prevent the odor generated at the time of decomposition of garbage by microorganisms from leaking from the inlet (7).

The reference numerals in parentheses attached to the respective means indicate the correspondence with specific means described in the embodiments described later.

A stirring blade 55 is provided in the portion. The stirring blade 55 efficiently dries the overflowed microbial carrier 40 and the garbage decomposition residue, and transfers the dried microbial carrier 40 and the garbage decomposition residue to the garbage treatment tank 2 adjacent to the drying tank 2b. On the other hand, it is scraped out into a detachable collection container 41.

As shown in FIG. 2, the gate 8 is in the open position X
And the closed position Y, the communication between the drain port 4 and the charging port 7 is established or cut off. The gate 8 is rotated by an electric motor, which is an electric driving means, or a rotating means such as a stepping force of the user himself. Here, the open position X is a position in which the gate 8 is housed in the discharge passage 12 and communicates between the drain port 4 and the input port 7, and the closed position Y is a position where the gate 8 is connected to the drain port. This is a position where the space between the inlet 4 and the inlet 7 is shut off.

A is a pipe forming an intake passage for supplying air into the garbage processing tank 2, and a pipe A is provided in the kitchen cabinet space below the sink 3 and in the garbage processing tank 2 (with the collection container 41 attached). Above the part) space. On the other hand, B is a pipe forming an exhaust passage for discharging gas (decomposed gas or water vapor generated by decomposition of garbage) in the garbage processing tank 2, and the pipe B connects the upper space in the decomposition tank 2 a with the outside. Communicating.

The pipe B is provided with a deodorizer 61 which is a deodorizing means for removing odor components from the gas passing through the pipe B. In this example, a thermocatalytic high-temperature deodorizer that oxidizes and decomposes odor components at a high temperature is used as the deodorizer 61. Although this type of deodorizer has excellent deodorizing performance, it has a relatively large ventilation resistance, so that pressure loss is likely to occur around the deodorizer 61.

The upstream side and the downstream side of the deodorizer 61 of the pipe B pass through the heat exchanger 62 and exchange heat between the gas heated by the deodorizer 61 and the gas flowing into the deodorizer 61. The energy required for gas heating at the time of deodorization by the deodorizer 61 is reduced. In this example, a double-pipe countercurrent heat exchanger is used as the heat exchanger 62.

Downstream of the heat exchanger 62 of the pipe B (downstream of the cooling passage of the heat exchanger 62), there is provided an electric fan 63 for feeding the air in the pipe B to the downstream side.
In this example, an electric fan of a type that drives a sirocco fan with an electric motor is used as the electric fan 63. When the electric fan 63 is operated, air is supplied into the garbage processing tank 2 through the pipe A, and gas in the garbage processing tank 2 is discharged through the pipe B. Therefore, the electric fan 63 is a ventilation fan serving as ventilation means in the present embodiment.

On the upstream side of the electric fan 63 of the pipe B, there is a pipe C which communicates the space inside the kitchen cabinet with the inside of the pipe B.
Is connected. When the deodorizer 61 and the electric fan 63 are operated, the gas heated at the time of deodorization and cooled by the heat exchanger 62 and the air sucked in through the pipe C are located downstream of the connection point between the pipes B and C. And a gas mixed with. Therefore, since a gas having a lower temperature than the gas flowing out of the heat exchanger 62 flows, the influence of heat on the electric fan 63 and piping components downstream thereof can be reduced.

A portion of the pipe B on the upstream side of the heat exchanger 62 (upstream of the heating side passage of the heat exchanger 62) and a connection point between the pipes B and C are connected by a pipe D. D is provided with an electromagnetic valve 65 which is an opening / closing means for communicating or blocking this path. The pipe D is a bypass passage that bypasses the deodorizer 61 provided in the pipe B.

Reference numeral 22 denotes a control device serving as control means. The control device 22 controls the stirring motor 5 based on input signals from the limit switch 20, the water content sensor 42 and the like.
3. It is configured to control the deodorizer 61, the electric fan 63, the electromagnetic valve 65, a heater (not shown), and the like.

Next, the garbage disposal apparatus 1 based on the above configuration
The operation of will be described.

The garbage is put into the sink 3 through the drain port 4,
As the garbage accumulates in the draining part 5, the water in the garbage naturally flows out from the plurality of small holes formed in the draining part 5 to the discharge path 12, and the garbage is drained. Done. At this time, the gate 8 is in the closed position Y and the drain 4
And the opening 7 are shut off. The water flowing out of the discharge passage 12 is sent to a drain pipe 14 through a drain trap 13.

When the user wants to dispose of the garbage deposited in the draining section 5, first, the gate 8 is turned from the closed position Y to the open position X, and the inlet 7 is opened. . Next, the draining part 5 is removed upward, and the garbage in the draining part 5 is discharged from the input port 7 through the transfer path 6 to the decomposition tank 2.
Send to a. After the garbage is sent to the decomposition tank 2a, the gate 8 is turned from the open position X to the closed position Y, and the space between the drain port 4 and the charging port 7 is shut off.

In the decomposition tank 2a, the stirring blade 50 is rotated to stir the garbage sent into the decomposition tank 2a and the microorganism carrier 40 in the decomposition tank 2a. Thereby, the garbage is decomposed by the microorganisms in the microorganism carrier 40 into decomposed gas and decomposed water. When the garbage decomposition residue in the decomposition tank 2a increases and a part of the microorganism carrier 40 and the garbage decomposition residue falls into the drying tank 2b, these are mixed with the stirring blades 5 in the drying tank 2b.
After being dried by rotation of 5, it is sent to the collection container 41.

Here, the control operation of the control device 22 will be described with reference to FIG.
This will be described with reference to the flowchart shown in FIG.

When the power of the garbage processing apparatus 1 is turned on,
First, the control device 22 includes the deodorizer 61 and the electric fan 6.
Activate 3 to ventilate the garbage disposal tank 2,
Power is supplied to a heater (not shown) to disassemble tank 2a and drying tank 2
b is heated (step S1).

Next, it is determined whether or not the gate 8 is at the open position X (step S2).
That is, the terminal 20a of the limit switch 20 in FIG.
When the limit switch 20 is in the ON state when the terminal 20b is brought into contact with the terminal 20b by the driving piece 21, the control device 22 that has received the ON signal sets the rotation speed of the electric fan 63 to the Hi level and opens the electromagnetic valve 65 ( Step S3).

As a result, air is supplied into the garbage processing tank 1 from the pipe A and the inlet 7, and the gas in the garbage processing tank 2 is discharged outside via the pipe B having the deodorizer 61 having a large pressure loss. And exhausted outside through a pipe D that bypasses a deodorizer 61 attached to the pipe B.

After executing step S3, it is next determined whether or not the gate 8 is at the closed position Y (step S4).
If it is in the closed position Y, that is, if the limit switch 20 is in the off state, the electromagnetic valve 65 is closed (step S
5) Shut off the pipe D.

If step S5 is executed, or if it is determined in step S2 that the gate 8 is not at the open position X, that is, if the gate 8 is at the closed position Y, the controller 2
2 executes normal disassembly control (step S6). When the normal disassembly control is performed, the control device 22 controls the air flow amount level of the electric fan 63 based on the signal from the moisture content sensor 42. For example, when the water content is 40% or more, the rotation speed of the electric fan 63 is set to the Hi level, the steam in the decomposition tank 2a is quickly discharged, and the water content is reduced. When the water content is less than 40%, the rotation speed of the electric fan 63 is set to the Lo level.

The control device 22 is provided with a moisture content sensor 42.
The operating state of the stirring motor 53 is also controlled based on the signal from For example, when the water content is 50% or more, the stirring motor 53 is operated for 30 seconds every 15 minutes to frequently stir the microorganism carrier 40 in the decomposition tank 2a and the inputted garbage,
The water contained in the microorganism carrier 40 and the garbage is diffused as steam into the garbage processing tank 2 to facilitate discharge. When the water content is less than 30%, the stirring motor 53 is turned on every 30 minutes.
It operates for 2 seconds, and when the water content is 30% or more and less than 50%, the operation interval is changed according to the water content.

Further, the controller 22 controls the water content sensor 4
Based on the signal from the control unit 2, the power supply state of a heater (not shown) is also controlled. For example, when the water content is 50% or more, the heater is controlled to generate heat so that the temperature in the decomposition tank 2a is 60 ° C.
The water contained in the microorganism carrier 40 and the garbage in the decomposition tank 2a is easily evaporated. When the water content is less than 30%, the heater is controlled to generate heat so that the temperature in the decomposition tank 2a becomes 40 ° C., and when the water content is 30% or more and less than 50%, the temperature is controlled according to the water content.

Incidentally, 60 ° C. is the upper limit temperature at which the bacteria carried on the microbial carrier 40 do not die. At 40 ° C., the bacteria carried on the microbial carrier 40 continue the decomposition of garbage and the decomposition tank 2a. This is the minimum temperature at which insects and the like do not occur. Therefore, at 40 ° C. to 60 ° C., the garbage is decomposed satisfactorily, and no insects appear in the decomposition tank 2a. Also, the heater (not shown) is set such that the temperature in the drying tank 2b is lower than the temperature in the decomposition tank 2a by 5 times.
The temperature is raised by about 10 ° C. to 10 ° C., so that the microorganism carrier 40 and the garbage decomposition residue in the drying tank 2b can always be dried.

After executing the normal disassembly control in step S6, the process returns to step S2.

According to the above configuration and operation, the charging port 7
Is closed, the operation of the electric fan 63 causes
Introducing outside air via pipe A and treatment layer 2 via pipe B
Internal gas is discharged, and the inside of the garbage disposal tank 2 is ventilated. Thereby, the oxygen required for the decomposition of garbage is supplied into the garbage processing tank 2. Also, when the inlet 7 is opened for the input of garbage, the electromagnetic valve 65 is opened and the deodorizer 61 is opened.
The gas in the garbage processing tank 2 can be exhausted also through a pipe D that bypasses the garbage.

Therefore, the flow rate of the air flowing from the inlet 7 toward the garbage disposal tank 2 can be increased because the deodorizer 61 is less affected by the pressure loss. That is, the flow velocity of the air at the inlet 7 can be increased. In this way, even if a large electric fan having a large maximum ventilation capacity is not employed, it is possible to prevent the odor from rising from the inlet 7 and leaking into the kitchen when the garbage is charged.

As described above, it is not necessary to employ a large-sized electric fan, so that the garbage disposal apparatus 1 does not become large. Further, since the electric fan need not have a large maximum ventilation capacity, power consumption does not increase.

The pipe B discharges the gas in the garbage disposal tank 2 to the outside. According to this, when the charging port 7 is opened for charging the garbage, the gas in the garbage processing tank 2 is exhausted from the pipe D that opens the electromagnetic valve 65 and bypasses the deodorizer 61. Although the odor leaks from the outlet, the odor can be exhausted to the outside, so that discomfort to the user can be prevented.

(Second Embodiment) Next, a second embodiment will be described with reference to FIGS.

The second embodiment differs from the first embodiment in the control of opening and closing the electromagnetic valve 65 performed by the control device 22. The same parts as those in the first embodiment are denoted by the same reference numerals, and description thereof will be omitted.

The schematic configuration of the garbage processing apparatus of the present embodiment is almost the same as that of the garbage processing apparatus 1 of the first embodiment shown in FIG. FIG. 4 is a diagram illustrating a schematic configuration of a pipe (bypass passage) D of the garbage processing apparatus according to the present embodiment.

As shown in FIG. 4, an exhaust passage for discharging the gas (decomposed gas generated by the decomposition of garbage, steam, etc.) in the garbage processing tank 2 to the outside is formed in the upper part of the garbage processing tank 2. The pipe B is connected, and gas is discharged by an electric fan 63 which is a ventilation means provided in the pipe B. The pipe B is located upstream of the position where the deodorizer 61 or the heat exchanger 62 is provided, and downstream of the pipe B not shown in FIG. 4 where the deodorizer 61 or the heat exchanger 62 is provided. And the part upstream of the position where the electric fan 63 is provided is a pipe D which is a bypass passage.
Connected.

As shown in FIG. 4, the pipe D has a substantially U-shape, and an electromagnetic valve 65 as an opening / closing means for communicating or blocking this path is provided at the lowermost portion. The pipe D has an upstream portion D1 that forms an upstream side from a position where the electromagnetic valve 65 is provided, and a downstream portion D2 that forms a downstream side.
It is composed of A suction port D3 on the side surface of the portion where the passage is arranged in the vertical direction of the downstream side portion D2, through which the inside of the pipe D communicates with the outside and through which air outside (inside the housing of the garbage disposal apparatus) can be sucked. Is provided.

Next, the control operation of the control device 22 will be described with reference to the flowchart shown in FIG.

The control operations from step S1 to step S6 are the same as those in the first embodiment. However,
If it is determined in step S2 that the gate 8 is not at the open position X, that is, if the gate 8 is at the closed position Y, the control device 22 determines whether or not the closed state of the electromagnetic valve 65 has continued for 12 hours or more (step S21). ). 1 when closed
If it is determined that the operation has continued for 2 hours or more, the electromagnetic valve 65 is opened (step S22), and after 30 seconds (step S23), the electromagnetic valve 65 is closed (step S24).

When step S24 is executed, or in step S21, the closed state of the electromagnetic valve 65 becomes 12
If it is determined that the operation has not continued for the time, the control device 22 executes the normal disassembly control (step S6).

The steam in the garbage disposal tank 2 is always in communication with the garbage decomposition tank 2 even when the electromagnetic valve 65 is closed, and is upstream of the pipe D which is lower in temperature than the garbage decomposition tank 2. It invades the side part D1 and forms dew on the inner wall of the upstream side part D1 to form dew. When the amount of dew water increases, the dew water accumulates at the bottom D11 of the upstream side part D1.

According to the flow shown in FIG.
5 is opened at least about every 12 hours, the dew condensation water adhering to the inner wall of the upstream side part D1 and the dew condensation water accumulated in the bottom part D11 are discharged from the garbage disposal tank 2 flowing through the pipe D when the electromagnetic valve 65 is opened. Due to the gas inside, it is sent from the upstream part D1 to the downstream part D2. That is, the condensed water does not remain in the upstream portion D1 for about 12 hours or more. The time of 12 hours is set in step S21 because, in the garbage disposal apparatus according to the present embodiment, in about 12 hours, dew condensation water is not generated enough to prevent gas from flowing into the pipe D. It is.

When the electromagnetic valve 65 is opened, the downstream side D2
When the electromagnetic valve 65 is closed, the condensed water stays at the bottom D21 of the downstream portion D2. The bottom part D21 of the downstream part D2 is the water trap part in the present embodiment.
However, even when the pipe D is closed while the electromagnetic valve 65 is closed, the electric fan 63 is always operating, and the processing of the garbage sucked from the suction port D3 is provided in the downstream portion D2 of the pipe D. Relatively dry air in the casing of the device flows downstream from the inlet D3.

The dew water remaining in the bottom 21 is dried by the air flowing through the downstream portion D2. That is, it is exhausted downstream as steam. The suction port D3 is provided on the side surface of the portion where the passage is arranged in the up-down direction of the downstream side portion D2, in order to surely send the condensed water retained in the bottom portion 21 downstream as steam.

For example, if the suction port D3 is provided above the most upstream part (immediately after the electromagnetic valve 65) of the downstream part D2, the bottom part D2
Although the effect of drying the condensed water accumulated in the bottom 21 is great, when the sucked air stream collides with the condensed water accumulated in the bottom portion 21, the condensed water becomes droplets and is sent downstream along with the air stream. If the condensed water is sent downstream in a water state, the water may adhere to the electric fan 63 which is a component disposed on the downstream side, and the life of the electric fan 63 may be reduced, which is not preferable. Therefore, it is preferable that the suction port D3 is provided on the side surface of the portion where the passage is arranged in the vertical direction of the downstream portion D2 above the level of the condensed water retained in the bottom portion D21.

The opening area of the suction port D3 needs to be smaller than the sectional area of the pipe D. If the opening area of the suction port D3 is large, even when the gate 8 opens the input port 7 and the electromagnetic valve 65 is opened to communicate with the pipe D, the flow velocity of the air flowing from the input port 7 is sufficiently increased. However, the odor in the garbage processing tank 2 may flow backward from the charging port 7, which is not preferable.

However, if the opening area of the suction port D3 is too small, the flow rate of the suction air decreases, causing a problem that the accumulated dew water cannot be sufficiently dried. The opening area of the suction port D3 needs to be an area that can secure an air flow rate that can dry the dew condensation water remaining in the bottom D21 within 12 hours. In this example, in order to satisfy both of these conditions, the diameter of the pipe D is 11 mm, while the diameter of the suction port D3 is 2 mm.
mm.

According to the above-described configuration and operation, it is possible to prevent the odor from rising from the inlet 7 and leaking into the kitchen when the garbage is thrown in, without employing a large electric fan having a large maximum ventilation capacity. The same effects as in the first embodiment can be obtained.

In addition to this, the pipe D which is a bypass passage
The dew water generated in the upstream side part D1 can be discharged as steam. Accordingly, the dew condensation water flows through the bypass
Can be prevented from interfering with the ventilation.

Further, as a measure for preventing the condensed water from hindering the ventilation of the pipe D, a method of providing a heating means for heating the pipe D in order to prevent the generation of the condensed water in the pipe D may be employed. However, according to the present embodiment, since the heating means for the pipe D is unnecessary, an increase in the number of components and an increase in power consumption can be suppressed.

In this embodiment, 12 hours, 11 hours
Real numerical values such as mm and 2 mm are mere examples, and can be appropriately set according to various characteristics of the garbage processing apparatus 1 and the like.

(Other Embodiments) In each of the above embodiments, the garbage disposal apparatus 1 is installed under the sink 3 of the kitchen, and the garbage is introduced from the inlet 7 communicating with the drain 4 of the sink 3. However, the inlet 7 may be located outside the sink 3 or the garbage disposal device 1 may be installed at a position other than below the sink 3. Further, it may be installed indoors other than the kitchen, or may be installed outdoors. However, the garbage disposal apparatus installed indoors including the kitchen has a greater effect of preventing discomfort to a user or the like due to odor leakage according to the present invention.

In each of the above embodiments, the limit switch 20 is used to detect the open state of the gate 8, but another gate open / close detector such as a magnet switch may be used.
Further, the gate opening / closing detector is attached at a position operated by the driving piece 21, but may be attached to a portion such as a foot pedal which is linked to the gate. Further, the gate opening / closing detector is mounted at a position for detecting a state where the gate 8 fully opens the inlet 7, but may be mounted at a position for detecting an intermediate state between the gate open position X and the gate closed position Y. When the gate 8 is opened and closed by an electric switch and power, the gate opening / closing detector may detect the electric signal.

In each of the above embodiments, the electric fan 63 is used as the ventilation means, but an electric pump or the like may be used.

Further, in each of the above embodiments, the electromagnetic valve 65 is used as the opening / closing means of the pipe D which is a bypass passage. A door member for communicating or blocking the door member may be provided, and the door member may be operated by the driving force of the servo motor.

In each of the above embodiments, the gate 8 has a spherical shape and is opened and closed by a rotating operation. However, if the gate 8 can shut off between the drain port 4 and the inlet port 7, the slide system may be used. Alternatively, another gate such as a desorption type may be used.

Further, in the second embodiment, the control for opening the electromagnetic valve 65 periodically and the configuration for ventilating to the downstream side D2 downstream of the electromagnetic valve 65 provide a piping D
The condensed water is discharged as water vapor to prevent the condensed water from obstructing the ventilation of the pipe D.
The upstream side of the electromagnetic valve 65 is configured such that dew condensation water formed inside can be drained to the upstream side of the pipe D (that is, in the garbage disposal tank 2) to prevent the dew condensation water from interfering with the ventilation of the pipe D. It may be to prevent.

For example, as shown in FIG. 6, the upstream side D101 of the pipe D is disposed so as to be inclined so that the condensed water generated inside can be drained to the upstream side. It may prevent the air from being hindered. According to this, the control for opening the electromagnetic valve 65 periodically and the installation of the suction port D3 become unnecessary.

In the second embodiment, the downstream portion D2 of the pipe D has a structure having the bottom portion 21 as a water trap portion. However, dew condensation water flows to downstream components such as the electric fan 63. If there is no problem even if it adheres, the downstream side portion D2 of the pipe D may have a structure without a water trap portion.

Further, in the second embodiment, the suction port D3 is provided at the downstream side D2 for the purpose of drying the dew condensation water. However, the pipe C provided for the purpose of reducing the thermal effect on the electric fan 63 and the like is provided. May be disposed at the position where the suction port D3 is provided, so that both of the above objects can be achieved.

Further, in each of the above embodiments, the garbage disposal tank 2 decomposes garbage with microorganisms. However, the garbage disposal tank 2 is not limited to this, and may be of a type for drying garbage.
