TECHNICAL FIELD OF THE INVENTION
The present invention relates to a garbage processing machine for drying garbage such as garbage.
[0002]
[Prior art]
2. Description of the Related Art Conventionally, there has been known a garbage disposer in which garbage such as garbage is kept in a dry state so as not to rot, and odor components generated during treatment are deodorized. Generally, such a kitchen waste processing machine is configured to deodorize and discharge steam generated by heating kitchen waste.
[0003]
Garbage is mainly generated in the kitchen, so it is convenient to install a garbage disposal machine indoors, but there are many factors that deteriorate the indoor environment, such as odor leakage, increased humidity due to the discharge of water vapor, and increased temperature due to heat sources. Indoor installation was difficult.
A garbage disposal machine that solves this problem is disclosed in Japanese Patent Application Laid-Open No. H11-169821. This garbage disposal machine puts garbage into the heating section and heats it, evaporates the water contained in the garbage, cools and condenses the gas in the condensing section communicating with the heating section, and reduces the water vapor content. The waste gas is forcibly sent back to the heating section through the circulation path by the fan to efficiently evaporate and dry the water contained in the garbage. It is drained to the outside and can be used indoors.
[0004]
[Problems to be solved by the invention]
However, in such a garbage disposer, the garbage is gradually dried from the outer surface, so the garbage is efficiently dried in the initial stage of heating and drying. It was difficult to dry sufficiently to the center.
As a result, the drying time becomes longer and the drying cost becomes higher.
An object of the present invention is to solve the above problems and efficiently dry garbage.
[0005]
[Means for Solving the Problems]
The garbage processing machine according to claim 1 of the present invention that solves the above problems,

The storage unit has a double structure including an inner container rotatable with the kitchen waste stored therein and an outer container storing the inner container,
A structure that allows water to pass through the peripheral wall of the inner container, and a rotation driving unit that rotates the inner container in a state where the rotation axis is inclined,
The gist of the invention is to form an inflow port for applying gas from the condensing unit to the kitchen waste falling while rotating in the inclined inner container in the storage unit.
[0006]
The garbage processing machine according to claim 2 of the present invention is the garbage processing machine according to claim 1,
A drainage port for dehydration is formed at the lowermost end of the outer container, and a trap for storing a certain amount of water is formed in the drainage portion,
The gist of the present invention is to provide a dewatering drainage channel that communicates the dewatering drainage port with the water reservoir of the trap.
[0007]
The garbage processing machine according to claim 3 of the present invention is the garbage processing machine according to claim 1 or 2,
Forming the opening of the inner container in the same direction as the opening of the outer container, providing a lid that can be opened and closed at the opening of the outer container,
The invention is characterized in that the lid has an outlet for sending gas in the outer container to the condenser, and the inlet, and the opening area of the inlet is smaller than the outlet.
[0008]
Further, the kitchen waste treatment machine according to claim 4 of the present invention is the kitchen waste treatment machine according to claim 3,
The point is that a filter is attached to the outlet.
[0009]
Moreover, the kitchen waste processing machine according to claim 5 of the present invention is the kitchen waste processing machine according to any one of claims 1 to 4,
The gist is that a stirring protrusion is provided on the inner peripheral wall of the inner container.
[0010]
The garbage disposer according to claim 1 of the present invention having the above configuration, even before the inner container is rotated, the moisture of the garbage is discharged to some extent from the inner container to the outer container by its own weight, and the garbage that has moved upward during the rotation is removed. It is further dehydrated by the force of falling.
The water remaining in the garbage after being dehydrated to some extent in this manner is further heated by the heating means and evaporates, sent to the condensing part by the returning means, condensed and drained from the drain part. The gas dried in the condensing section returns to the storage section from the inflow port and is applied to the kitchen waste.
The garbage is lifted by the rotation of the inner container, and when it falls apart and falls, it comes into sufficient contact with the dried gas and dries quickly. By repeating this cycle, efficient drying is performed.
[0011]
Further, the kitchen waste disposal machine according to claim 2 of the present invention can drain water from the outer container using the drainage section. In this case, the trap of the drainage section can be used for both drainage from the condenser section and drainage from the dewatering drainage channel. That is, it is possible to prevent the odor from the outside such as a sewer pipe from entering the outer container through the drainage drainage channel by using the trap of the drainage part.
In addition, since the drainage drainage channel is connected to the water storage portion of the trap, the communication path between the condensation portion and the drainage drainage channel is blocked by the water in the water storage portion. As a result, the gas from the condenser does not flow to the outer container (outside the inner container) through the drainage drainage channel, but all the gas is applied to the garbage falling in the inner container, and the garbage is dried. Used for

Further, in the garbage processing machine according to claim 3 of the present invention, an inflow opening having a small opening area is provided in a lid portion facing the garbage, and dry gas is blown from the inflow opening toward the garbage at a high speed. dry.
Moreover, since the inflow port is narrower than the outflow port, the pressure difference between the upstream side and the downstream side of the inflow port is maintained. That is, the storage section is maintained in a low pressure state. As a result, it becomes possible to evaporate water at a low temperature with a reduced boiling point, and it is difficult for odor to leak to the outside.
[0013]
Further, in the kitchen waste treatment machine according to claim 4 of the present invention, since the gas sent to the condenser passes through the filter at the outlet, dust generated from the kitchen waste can be prevented from adhering to the heat exchange surface of the condenser. In addition, the condensation efficiency can be maintained satisfactorily for a long time.
Furthermore, since the opening area of the outlet is larger than that of the inlet, a large filter area can be ensured while keeping the flow path resistance small. As a result, it is possible to suppress an increase in the pressure in the storage section, and it is difficult for the filter to be clogged.
[0014]
Further, in the garbage disposer according to claim 5 of the present invention, the agitating projection catches and lifts a large amount of garbage, and then drops the garbage, thereby increasing the contact with the dried gas.
[0015]
BEST MODE FOR CARRYING OUT THE INVENTION
In order to further clarify the configuration and operation of the present invention described above, a preferred embodiment of a kitchen waste disposal machine of the present invention will be described below.
[0016]
A garbage processing machine as one embodiment of the present invention will be described with reference to FIGS. FIG. 2 is a diagram in which the heating unit of the kitchen waste treatment machine shown in FIG. 3 is cut along a cutting line AA ′. The kitchen waste disposal machine is arranged in a kitchen cabinet.
As shown in FIG. 1, the kitchen garbage disposer is roughly divided into a heating unit 10 for heating the garbage G with an electric heater (hereinafter referred to as an inner heater 14), and a condensing unit for condensing water vapor generated from the garbage G. 20, a cut-off drain section 30 (drain section) for shutting off and draining a flow path connecting the condenser section 20 and the drain pipe 1 (may be a drain pipe of a kitchen sink), and a gas cooled by the condenser section 20 Is returned to the heating unit 10 again, and a controller (not shown) for controlling heating, air blowing, and the like.
[0017]
The condensing unit 20 includes a fin tube 21, and cools the gas in the fin tube 21 by heat exchange with the outside air to condense the water contained in the gas.
The cutoff drain section 30 includes an S-shaped trap 31 and a dewatering drainage channel 35 described later. The trap 31 has a downstream flow path 32 through which water from the fin tube 21 flows downward, and a downstream flow path 32. An upward flow path 33 that rises once from the path 32 and a drainage flow path 34 that communicates with the drain 1 again from the upward flow path 33 are formed. Reference numeral 31a denotes a water storage portion for storing a certain amount of water in the trap 31, and indicates a portion below a water storage upper end portion c which is a lower end of a connection portion between the upflow channel 33 and the drainage channel 34.
[0018]
The return section 40 is provided in the air supply pipe 41 communicating the heating section 10 and the upper end of the fin tube 21 of the condenser section 20, the return pipe 42 communicating the lower end of the fin tube 21 and the heating section 10, and the air supply pipe 41. The fan 43 sucks the gas in the heating unit 10, sends the gas to the fin tube 21, and returns the fan 43 to the heating unit 10 again, and a return tube electric heater (hereinafter, referred to as an outer heater 44) for heating the return tube 42. And
Note that bellows portions 41a and 42a are formed on the heating section 10 side of the air supply pipe 41 and the return pipe 42, respectively.
[0019]
As shown in FIGS. 2 and 3, the heating unit 10 includes an inner container 11 for storing garbage G (not shown in FIG. 3) and an outer container 12 for storing the inner container 11 at a predetermined interval. And a storage unit 13 having a double structure.
The inner container 11 and the outer container 12 are provided by inclining a stainless steel bottomed cylinder having openings 11e and 12e formed on the upper surface thereof at an angle θ (here, 30 degrees) from the horizontal direction. The opening 11 e of the inner container 11 is formed in the same direction as the opening 12 e of the outer container 12.
[0020]
The inner container 11 is made of a punching metal (a metal net may be used) in which a number of small holes 11c through which water can pass are formed in the peripheral wall portion 11a and the bottom portion 11b. A large number of flat rectangular stirring blades 11d (protruding portions for stirring) extending toward the central axis are provided on the peripheral wall portion 11a.
[0021]
An inner heater 14 (heating means) for heating and drying the garbage G is provided above the peripheral wall 12 a of the outer container 12 in a meandering manner on the inner peripheral surface of the outer container 12.
On the other hand, in the lower part of the peripheral wall portion 12a of the outer container 12, four recesses 12c are formed in front, rear, left and right, and rollers 15 rotating in each recess 12c are provided.
A motor 17 (rotation driving means) is provided outside the outer container 12, and only one of the four rollers 15 (here, the right rear roller 15a) is rotationally driven.
The inner container 11 is supported by the four rollers 15, and is configured to rotate slowly about a tilted central axis as a rotation axis by a roller 15a rotated and driven by a motor 17.
[0022]
In addition, a cover 18 that opens and closes to open and close the inner container 11 is provided in the opening 12 e of the outer container 12, and can be opened and closed by a hinge 18 d fixed to the peripheral wall portion 12 a of the outer container 12. The lid 18 has an outlet 18 a connected to the air supply pipe 41 and a nozzle 18 b (inlet) connected to the return pipe 42. The nozzle 18b is arranged near the rotation axis of the inner container 11, and has an opening area smaller than the outlet 18a. In addition, a filter 18c is attached to the outlet 18a.
[0023]
On the bottom surface portion 12b of the outer container 12, a drainage drainage port 12d is formed at the lowermost position. As shown in FIG. 1, the dewatering drainage port 12d and the water storage portion 31a (here, the downstream A dewatering drainage channel 35 is provided for connection with the position b) below the channel 32.
In addition, the code | symbol a shows the upper end of the connection part of the down flow path 32 and the up flow path 33. Further, the position b is higher than the position a and lower than the upper end c of the water storage.
[0024]
Next, the operation of the kitchen waste disposal machine will be described.
First, when the lid 18 is opened and the inner container 11 in which the garbage G is put is stored in the outer container 12, or when the garbage G is put into the inner container 11 in the outer container 12, the garbage G is included in the garbage G. The discharged water passes through the small hole 11c of the inner container 11 and is discharged to the outer container 12 by its own weight, flows down the peripheral wall 12a of the inclined outer container 12 to the drainage drainage port 12d, and flows through the drainage drainage channel 35. It passes through and accumulates in the trap 31.
[0025]
Then, the motor 17 and the inner heater 14 are operated by a start operation of the drying process.
The motor 17 drives the roller 15a (FIGS. 2 and 3) to rotate, and the inner container 11 in contact with the roller 15a also rotates. Since the other rollers 15 also rotate by the rotation of the inner container 11, the inner container 11 rotates smoothly while maintaining its position.
While the inner container 11 is rotating, the garbage G is repeatedly lifted and dropped by the stirring blades 11d. When the garbage G falls, it collides with the inner peripheral surface of the inner container 11, and the garbage G is further dehydrated.
[0026]
In addition, the garbage G is heated by the inner heater 14, and the moisture evaporates. When the water in the trap 31 has not reached the water level a, the air existing in the outer vessel 12 and the fin tube 21 is pushed out to the sewer pipe 1 by the generation of steam.
[0027]
On the other hand, when a predetermined time has elapsed from the start of heating by the inner heater 14, the fan 43 and the outer heater 44 (heating means) of the return section 40 are operated. The gas containing a large amount of water vapor in the outer container 12 flows through the filter 18c of the outlet 18a to the condenser 20 and is cooled when passing through the fin tube 21. At this time, since the gas sent to the fin tube 21 is cooled, water vapor contained in the gas is condensed and becomes water to flow down to the trap 31.
When the gas having a reduced water vapor content flows through the return pipe 42, the gas is heated to a high temperature by the outer heater 44 to have a low humidity and is sent back to the outer container 12, and is dropped in the inner container 11. It is jetted from the nozzle 18b toward the garbage G.
[0028]
Since the garbage G falls apart when falling while rotating in the inner container 11, the contact area with the dried gas increases, and the evaporation of moisture can be promoted.
Further, the relative humidity of the gas immediately after passing through the fin tube 21 is close to 100%, but the temperature is increased by the external heater 44 and the saturated amount of water vapor is increased. Although not changed, the relative humidity is greatly reduced. Drying of the garbage G is promoted by the low humidity and high temperature gas.
[0029]
The water condensed in the condensing section 20 and flowing down to the trap 31 accumulates in a U-shaped portion connected from the down flow path 32 to the up flow path 33, and the accumulated water rises to a water level a, so that the down flow path 32 The gas flow path from the to the upstream flow path 33 is shut off. As a result, the space including the outer container 12 and the fin tube 21 is sealed from the outside.
Further, when water accumulates to the water level b, the gas flow path from the down flow path 32 to the dewatering drain path 35 is also shut off.
[0030]
In this way, the water that flows down from the fin tube 21 and the drainage drainage pipe 35 accumulates in the trap 31, but the water in the upward flow path 33 exceeding the water level c is reduced via the drainage flow path 34. Since the water flows into the water pipe 1, the water level does not increase and the water level is stabilized.
In addition, since the water level difference between the downstream flow path 32 and the upstream flow path 33 is determined by the pressure difference between the inside of the closed space and the inside of the sewer pipe 1, in a state where the pressure in the closed space is a negative pressure value. Stable at water level d higher than water level c. On the other hand, since the pressure of the dewatering drainage channel 35 and the outer container 12 is lower than that of the return pipe 42, the water in the dewatering drainage channel 35 is stabilized at a water level e higher than the water level d of the downstream flow path 32.
Most of the odor components generated from the garbage G are dissolved in the water stored in the trap 31 and drained to the drain 1. Moreover, the pressure in the closed space is naturally adjusted by the trap 31.
[0031]
In the sealed space water-sealed by the trap 31, a part of the air existing at the start of the operation is pushed out to the side of the sewer pipe 1, so that the content of water vapor in the gas increases. Further, the amount of heat taken by the fin tube 21 is made larger than the amount of heat given by the outer container 12, and the generated water vapor is surely condensed and discharged as moisture, so that the whole inside of the closed space is slightly negatively pressurized. Can be.
In addition, since the opening area of the nozzle 18b of the return pipe 42 is small, the nozzle 18b allows the upstream side (low pressure side of the outer vessel 12 and the like) and the downstream side (high pressure side of the return pipe 42 and the like) of the fan 43 in the gas circulation path. And the pressure difference can be maintained. On the other hand, the outlet 18a has a larger opening area than the nozzle 18b, and the flow resistance is smaller than that of the nozzle 18b even when the filter 18c is mounted inside. Therefore, the pressure loss at the outlet 18a is small, The pressure can be maintained as low as the inlet pressure of the fan 43.
As described above, the inside of the outer container 12 has a slight negative pressure, so that the boiling point is lowered and it is possible to evaporate water at a low temperature. Water vapor from the garbage G is condensed and drained together with the odor, thereby preventing odor leakage and humidity rise, and does not deteriorate the indoor environment of the kitchen.
[0032]
Further, even if the gas sent from the outer container 12 to the condenser 20 contains dust generated from the garbage G, the dust is collected by the filter 18c, so that the dust does not adhere to the inner peripheral surface of the fin tube 21. As a result, the heat exchange is not hindered, the condensation is favorably performed, and the water in the circulating gas can be efficiently removed.
In addition, since the opening area of the outlet 18a is large, a large surface area of the filter 18c can be secured while keeping the passage resistance small. As a result, the pressure increase in the outer container 12 due to the outlet 18a is suppressed, and the filter 18c is less likely to be clogged, so that the kitchen waste disposal machine can be used efficiently for a long period of time.
[0033]
Further, since the opening area of the nozzle 18b is small, the flow path resistance of the return pipe 42 becomes larger than that of the dewatering drainage channel 35. However, since the dewatering drainage channel 35 communicates with the water storage part 31a of the trap 31, The gas flow path is blocked by the water accumulated in the section 31a, and all the gas dried through the condensing section 21 is sent into the inner container 11, and can be reliably applied to the garbage G, and the drying is promoted. .
Further, since the dewatering drainage channel 35 and the downstream flow channel 32 are configured to be shut off by the water in the water storage portion 31a, the gas that has passed through the condensing portion 21 is separated into the return pipe 42 and the dewatering drainage channel 35. That is, it does not flow backward to the drainage drainage channel 35 and is not sent to the space between the outer container 12 and the inner container 11. Therefore, all the gas from the condenser 21 can be directly blown onto the garbage G in the inner container 11, and the garbage G can be efficiently dried.
[0034]
In addition, since the drainage from the condensing section 20 and the drainage from the dewatering drainage channel 35 are shared by one trap 31, it can be manufactured at low cost and can be reduced in space and compact. Moreover, the backflow of the odor from the drain pipe 1 to the drainage drainage channel 35 and the condensing section 21 can be prevented with only one trap 31.
[0035]
According to the above-mentioned kitchen garbage disposer, the garbage G can be dehydrated to some extent before the drying start operation. Further, during the heating by the inner heater 14, the garbage G is dropped by the rotation of the inner container 11, thereby promoting the dehydration. At the same time, the water vapor in the garbage G evaporates due to the heating. In addition, the garbage G falls apart when it is lifted by the rotation of the inner container 11 and then falls, so that it comes into sufficient contact with the dried gas.
As described above, since dehydration and evaporation are combined and the dried gas is evenly applied to the garbage G, drying can be performed efficiently. As a result, the drying time is shortened, and the cost of electricity for heating can be kept low, which is economical.
[0036]
Further, the garbage G is stirred with the rotation of the inner container 11, and the dried portion and the undried portion of the garbage G are mixed well. Can be dried.
Further, since the nozzle 18b is provided on the lid 18 facing the garbage G, it is possible to directly blow dry gas onto the garbage G. Moreover, since the opening area is small, the jetting force is strong, and the dried gas can be applied to the garbage G at the back.
[0037]
Although the embodiments of the present invention have been described above, the present invention is not limited to these embodiments at all, and it goes without saying that the present invention can be implemented in various modes without departing from the gist of the present invention.
For example, instead of the inner heater 14, a configuration in which the garbage G is heated by, for example, a gas burner or a microwave may be used.
Further, a configuration may be employed in which the water in the garbage G is evaporated by hot air heated by the outer heater 44 without the inner heater 14.
The outer heater 44 does not necessarily have to be provided. In this case, since the temperature of the gas from the condensing section 21 rises in the outer container 12 to become dry air, the drying process of the garbage G can be performed at low cost.
[0038]
Further, the condensing unit 20 is not limited to natural cooling. For example, the condensing unit 20 may be configured to be cooled by blowing air from the outside with a fan, or may be configured to be cooled by water from a kitchen sink.
In addition, the stirring protrusion provided on the inner peripheral wall of the inner container 11 is not limited to a flat plate such as the stirring blade 11d, and may be a twisted plate or a conical protrusion. The shape is not limited as long as the garbage G is hooked up from the lower part of the inner container 11 to the upper part.
[0039]
【The invention's effect】
As described above in detail, according to the garbage disposal machine of claim 1 of the present invention, the garbage is dewatered, and the garbage is rotated and separated, and the dried gas is evenly applied to the garbage. Can be dried. As a result, the drying time is shortened, and the required heating amount is reduced to save energy.
[0040]
Further, according to the garbage treatment machine of the second aspect of the present invention, since the dewatering drainage channel communicates with the trap water storage portion, it can also be used as a trap for the condensed water drainage portion to reduce the manufacturing cost. In addition, the space can be saved and the device can be made compact. In addition, the lower end of the dewatering drainage channel is blocked by water, so that all the gas that has passed through the condensing section can be sent to the inside of the inner container and reliably hit on the garbage for drying.
[0041]
Furthermore, according to the garbage disposal machine of the third aspect of the present invention, since the inflow port having a small opening area is provided in the lid portion facing the garbage, it is possible to blow dry gas toward the garbage, thereby promoting drying. In addition, since the inside of the outer container is maintained at a negative pressure by the inflow port to easily evaporate the moisture of the garbage, drying can be performed more efficiently.
[0042]
Furthermore, according to the garbage processing machine of the fourth aspect of the present invention, since the filter is attached to the outlet having a large opening area, clogging of the filter can be suppressed, and the rise in the pressure in the storage portion is suppressed at the outlet. In addition to making it easier to evaporate, it is possible to prevent the dust from the garbage from adhering to the heat exchange surface of the condensing portion and efficiently condense it, thereby further shortening the drying time.
[0043]
Furthermore, according to the garbage disposer of claim 5 of the present invention, since a large amount of garbage is lifted by the agitating projection, the amount of garbage that comes into contact with the dried gas can be increased and drying can be performed in a short time.
