DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a garbage disposer for drying garbage such as garbage.

[0002]

2. Description of the Related Art Heretofore, as this type of kitchen waste disposal machine, there is known a kitchen waste disposal machine for drying kitchen waste such as garbage so as not to rot, and for deodorizing odor components generated during processing. . Such a kitchen waste treatment machine has a structure in which steam generated by heating kitchen waste is deodorized and discharged.

Since garbage is mainly generated in kitchens, it is convenient to install a garbage disposer indoors. However, garbage is generated, the humidity rises due to the discharge of water vapor, and the temperature of room temperature is reduced by heat sources. It is difficult to install a kitchen waste disposal machine indoors, because such factors cause deterioration of the indoor environment such as rising. On the other hand, a heating unit that heats the garbage stored in the processing tank with the main heater that heats the processing tank, and a condensing unit that cools and condenses steam are provided, and the heating unit is heated by the steam generated by heating the garbage. This space is closed while gas present in the space that communicates with the condensing part is extruded, and the amount of water vapor condensed is increased to reduce the pressure in this closed space (hereinafter referred to as the closed space) to a negative pressure. And drying treatment.

[0004] By applying a negative pressure to the closed space in this way, it is possible to prevent odor from leaking from a sealing portion such as a lid, and to lower the boiling point of steam to perform low-temperature treatment. In addition, since odor and water vapor do not need to be discharged indoors by draining odor components generated from kitchen waste together with condensed water to an external drainage mechanism such as a sewer pipe, a kitchen waste treatment machine can be used indoors. can do. In particular,
By housing the garbage disposal machine in kitchen equipment such as a sink cabinet, the garbage disposal machine can be arranged without providing a separate space and invisible from the surroundings, which is preferable.

In this garbage disposer, the gas in the space is extruded by the steam and the majority of the sealed gas is converted into steam, so that the volume shrinkage when the gas is cooled in the condensing section can be increased. Therefore, the steam generated in the heating section can be smoothly flowed into the condensation section. As a mechanism for forming such a closed space, while storing the water discharged from the condensing section, it is connected to a storing section for shielding the heating section and the condensing section side from the outside air, and to an opening provided on a side portion of the storing section. And a drain portion extending to the outside and having a discharge path connected to a sewer pipe or the like.

[0006]

By the way, in this kitchen garbage processing machine, from the beginning of the kitchen garbage drying process, the kitchen garbage stored in the processing tub is heated from the wall side of the processing tub by the main heater, and the kitchen garbage is heated. The garbage in the garbage is dried by evaporating the water. By continuing the heating, the garbage in the portion close to the treatment tank is first dried by the evaporation of the water. The dried garbage layer thus serves as a heat insulating layer, which prevents the propagation of heat from the main heater to the entire garbage.
Therefore, there is a problem that not only the heating efficiency of the main heater is reduced, but also the temperature around the garbage processing machine is increased by excessively heating the processing tank to become high temperature and radiating heat to the outside. In particular, when the kitchen waste disposal machine is housed in a closed space such as a kitchen appliance such as a sink cabinet, heat radiation from the treatment tank heats up the interior of the space, thereby damaging the appliance. And so on.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problem, and it is possible to suppress an excessive rise in temperature of a processing tank itself for storing garbage, increase a heating efficiency of a main heater, and prevent a rise in ambient temperature. The purpose is to provide a machine.

[0008]

In order to achieve the above-mentioned object, a structural feature of the invention according to the first aspect is that a garbage such as garbage stored in a processing tank is heated by a main heater for heating the processing tank. A heating unit for heating, a condensing unit that communicates with the heating unit and cools the gas containing water vapor generated from the garbage, a drainage unit that drains water condensed in the condensing unit to the outside, and heats the gas cooled in the condensing unit And a return heater for heating the gas cooled in the condensing section which is forcibly sent back to the heating section by the returning means. There is provided a heating ratio changing means which can change the heating ratio during the drying process of the garbage.

According to the invention of the first aspect, kitchen waste such as garbage stored in the processing tank by the heating unit is heated by the main heater from the processing tank wall side and included in the kitchen waste. The evaporating water evaporates and cools the gas in the condensing section communicating with the heating section to condense the water vapor. Furthermore, the gas cooled in the condensing section is forcibly sent back to the heating section by the return means, so that the gas containing a large amount of water vapor in the heating section is smoothly sent to the condensing section, and the gas cooled in the condensing section is contained in the steam. The gas whose amount has been greatly reduced is returned to the heating section again. Therefore, the water contained in the kitchen waste can be efficiently evaporated, and the water vapor can be efficiently condensed. Further, most of the odor generated from the kitchen garbage can be drained together with the condensed water from the drainage section to a sewer pipe or the like outside the kitchen garbage disposal machine.

Further, according to the first aspect of the present invention, at the time of starting the drying process of the garbage, the garbage stored in the processing tank is heated from the inside by the main heater, so that the garbage can be centered on the portion close to the processing tank. When heated, the moisture contained therein becomes water vapor and starts to evaporate smoothly. Further, if the process of heating the garbage is continued, the garbage mainly in a portion close to the processing tank is dried by heating, and the moisture contained therein is lost by evaporation. As a result, the garbage in the portion close to the processing tank acts as a heat insulating layer, and the transfer of heat from the main heater to the entire garbage in the processing tank becomes worse. The heating ratio with the return heater is changed, and the heating by the return heater is mainly performed from the heating by the main heater. That is, the gas returned from the condensing section to the heating section is heated by the heating of the return heater, and is sprayed on the kitchen garbage exposed in the processing tank. For this reason, the heating from the processing tank is set to zero or zero, while the exposed kitchen waste other than the part near the processing tank is efficiently heated by the gas heated by the return heater. Therefore, it is possible to prevent the heating efficiency of the heater from being lowered and prevent the processing tank from being excessively heated.

[0011] Further, a structural feature of the invention according to claim 2 is that, in the kitchen garbage processing machine according to claim 1, the heating ratio changing means changes the heating ratio at the time of starting the drying process of the garbage. Is defined by the elapsed time. Thus, the timing of changing the heating ratio can be appropriately set in advance according to the capacity of the processing tank, the amount of kitchen waste, and the like.

[0012] Further, a structural feature of the invention according to claim 3 is that, in the kitchen garbage processing machine according to claim 1, the heating rate changing means for changing the heating rate by the heating rate changing means is provided in the processing tank or its surroundings. It is specified by temperature.
The temperature around the processing tank refers to the temperature of the space around the processing tank, the temperature of kitchen waste close to the processing tank, and the like. This makes it possible to easily detect the drying state of the kitchen garbage based on the temperature change of the kitchen garbage and the like, and to appropriately define the timing of changing the heating ratio regardless of the capacity of the processing tank and the amount of the kitchen garbage.

[0013]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a schematic configuration of a kitchen waste disposal machine installed in a sink cabinet K of a kitchen according to a first embodiment. 2 is shown in a sectional view, and FIG.
Fig. 3 schematically shows the state of installation of the kitchen waste disposal machine in the sink cabinet K.

The kitchen waste disposal machine includes a heating unit 10 for heating the garbage A, a condensing unit 20 for condensing water vapor generated from the garbage A in the heating unit 10, a condensing unit 20 and an external sewage pipe G.
And a blocking means for draining the water according to the state of the stored water, and a return means 40 for returning the gas cooled in the condenser 20 to the heater 10 again.
And a control device 50 for controlling the operation of the processor.

The heating unit 10 includes a heating chamber 11 having an adiabatic closed structure for accommodating a processing tank 12 for storing garbage A, and a processing tank 1.
2 is provided with a main heater 13 provided outside the bottom surface for heating the processing tank 12. On the upper surface of the heating chamber 11, the processing tank 1
A cover 14 is provided to open and close an opening for taking in and out of the unit 2. However, the lid 14 may be provided on one side surface of the heating chamber 11. A temperature sensor 16 for detecting the temperature of the processing tank 12 is provided on an outer wall of the processing tank 12, and the temperature sensor 16 is connected to an input side of a control device 50 described later.

The condensing section 20 is constituted by a fin tube type heat exchanger 22, and the upstream side thereof is a communication pipe 21.
The heating chamber 11 communicates with the upper end of the side surface of the heating chamber 11, and the downstream side is connected to the cutoff drain section 30 and the return means 40 via the communication pipe 23. The lower end of the communication pipe 23
It is connected to a suction side of a fan 42 described later. In addition,
Instead of using a fin tube type heat exchanger, the condensing section may have a structure in which a plurality of pipes are juxtaposed at an arbitrary inclination.

The cut-off drain section 30 includes a tank 31 for storing water.
A condensed water discharge pipe 32 which is connected to the discharge side of the fan 42, penetrates the upper surface of the tank 31 and faces down to the bottom surface thereof, and allows water from the condensing section 20 to flow downward; Is a drainage channel that is connected to the opening 31a, communicates with the tank 31 and the sewer pipe G, and drains to the sewer pipe G water that exceeds the lower end of the opening 31a that is the set water level b in the tank 31. And a pipe 33.

The return means 40 includes a return pipe 41 branched from the condensed water discharge pipe 32 and connected to a side wall of the heating chamber 11 to communicate the condensing section 20 and the heating section 10 with each other.
3 and a fan 42 connected to the lower end side. The fan 42 forcibly flows the gas cooled by the condenser 20 toward the heating chamber 11. At the end of the return pipe 41 on the heating unit 10 side, a nozzle 43 for injecting gas toward the garbage A in the heating chamber 11 is provided. A return heater 45 is provided in a part of the return pipe 41. The return heater 45 is a linear heater wound around the return tube 41, but may be a plate-like or tubular-like other heater. Further, a heater of a type embedded in the return pipe 41 may be used.

The control device 50 is composed of a control section composed of a microcomputer or the like, and a drive section. Based on a "drying control program" shown in FIG. 3, the drive of the fan 42, the main heater 13 and The switching drive of the return heater 45 is controlled. The switching control of the heater 45 back to the main heater 13, switching from the main heater 13 and returns the heater 45 from the start of the drying process operation after a predetermined switching time t _C lapse back only to the heater 45 is performed. The switching time t _C means a time required for the garbage located in the vicinity of the processing tank 12 to be sufficiently dried by heating of the main heater 13, and is defined in advance by the capacity of the processing tank, the amount of the garbage, and the like. For about one hour, for example. Also,
Regarding the control of the heating ratio of the main heater 13 and the return heater 45, either one can be set to 100% and the other can be set to 0%, but it is also possible to simultaneously heat both at a predetermined ratio.

Next, the operation of the kitchen waste disposal machine configured as described above will be described. In the heating chamber 11, the processing tank 12 into which the garbage A is put is accommodated, and after the lid 14 is closed, the power is turned on and the control device 50 starts the execution of the "drying control program", and the fan After performing initialization processing of various variables such as turning off the return heater 45 and the return heater 45, heating by the main heater 13 and the return heater 45 is started, the fan 42 is turned on, and the drying process of the garbage A is performed ( Steps 60-63). At the start of the drying process, the heating chamber 11, the condensing section 20, and the inside of each pipe are at atmospheric pressure. Therefore, as shown in FIG. 4A, the water level in the tank 31 and the water level in the condensed water discharge pipe 32 are reduced. It is the same.

The heating raises the temperature in the processing tank 12 and the heating chamber 11 to evaporate the water contained in the garbage A and expand the air in the heating chamber 11, so that the inside of the heating chamber 11 is pressurized. You. The pressure increase in the heating chamber 11 is transmitted to the water in the condensed water discharge pipe 32, and the water surface in the condensed water discharge pipe 32 is pushed down. When the water level in the condensed water discharge pipe 32 reaches the water level a at the tip (lower end) of the pipe, as shown in FIG. The gas is discharged into the tank 31 and the pressure in the heating chamber 11 stops rising. That is, the pressure rise in the heating chamber 11 is limited by the level difference h ₁ in the tank 31.

On the other hand, when a certain time has passed since the start of heating by the main heater 13 and the return heater 45, the heating chamber 11
The gas containing a large amount of water vapor therein flows into the condensing section 20, is cooled when passing through the heat exchanger 22, and is returned to the heating chamber 11 through the return pipe 41. At this time, the gas sent from the heating chamber 11 to the heat exchanger 22 is cooled and the dew point is lowered, so that the water vapor contained in the gas is condensed into water and flows down through the communication pipe 23 and the condensed water discharge pipe 32. And flows down into the tank 31.

Since the heating chamber 11 is isolated from the atmosphere by the condensed water stored in the tank 31, the pressure in the closed space including the heating chamber 11 and the condensing section 20 gradually decreases due to the condensation of water vapor. When the pressure is lower than the atmospheric pressure, the water in the tank 31 is sucked into the condensed water discharge pipe 32, and the water level of the condensed water discharge pipe 32 rises above the water level in the tank 31 as shown in FIG. Further, since the inside of the heating chamber 11 has a negative pressure, the boiling point of water vapor in the heating chamber 11 is reduced, and water can be evaporated at a low temperature. From the outside to the outside. Further, most of the odor components generated from the kitchen garbage dissolve in the condensed water, and are discharged together with the condensed water.

The gas having a reduced water vapor content in the condensing section 20 flows through the return pipe 41 and is injected by the nozzle 43 into the garbage A in the processing tank 12. By directly injecting the gas with reduced humidity into the garbage A, the evaporation of the water contained in the garbage A is promoted.

On the other hand, the condensed water that continues to flow down from the condensing section 20 accumulates in the tank 31. Since the water in the tank 31 that exceeds the set water level b flows through the discharge pipe 32 to the sewer pipe G, Water does not grow too much. For this reason, the water surface on the tank 31 side does not become higher than the set water level b, so that the pressure increase in the closed space due to the rise of the water surface is prevented, and as a result, odor leakage from the heating chamber 11 can be prevented.

When the pressure in the enclosed space drops significantly below the atmospheric pressure, the water level in the condensed water discharge pipe 32 rises, and the water level in the tank 31 falls, and the tank 31 When the water inside falls to water level a,
As shown in (d), the gas in the tank 31 is sucked into the condensed water discharge pipe 32. Therefore, the pressure in the enclosed space is
Only it drops to a predetermined value determined by the water level h ₂ of the condensed water in the exhaust pipe 32 based on the level difference h _1.

By continuing to heat the processing tank 12 by the main heater 13, the garbage in the vicinity of the wall of the processing tank 12 in the garbage stored in the processing tank 12 is sufficiently heated and dried. This kitchen waste acts as a heat insulating layer, and it becomes difficult for the heat from the main heater 13 to be efficiently transmitted to the kitchen waste. By leaving such a state, the processing tank 12 is excessively heated, and the heat is radiated to the surroundings, thereby increasing the ambient temperature. Here, the above-mentioned predetermined switching time t to be in such a heating state.
After passing _C , the control device 50 changes the heating rate,
The heating of the main heater 13 is stopped, and the return heater 4 is stopped.
Only 5 is heated (steps 64 and 65).

Therefore, the processing tank 12 is not heated any more, so that the kitchen waste in the vicinity of the wall in the processing tank 12 is not heated. On the other hand, the kitchen waste other than the portion adjacent to the processing tank 12 is heated by the return heater 45 and is heated.
The gas returned to the garbage is sprayed through the nozzle 43 and sprayed on the exposed garbage, thereby heating the garbage very efficiently.

As a result, the entire kitchen waste can be efficiently heated without lowering the heating efficiency of the heater, and the drying performance of the kitchen waste treatment machine can be improved. Further, it is possible to reliably prevent the disadvantage that the temperature of the processing tank 12 rises due to excessive heating, and the high heat is radiated to increase the ambient temperature.
Therefore, even if the kitchen waste disposal machine is installed in a closed space such as a sink cabinet, it is possible to suppress a rise in the temperature of the internal space, thereby causing thermal damage to the sink cabinet and objects contained in the cabinet. Properly installed without giving. In addition, the kitchen waste disposal machine can be installed in a compact form without being noticed, which is convenient. Then, when a predetermined drying processing time t _S has elapsed, the return heater 45 is turned off, and when the temperature T of the processing bath 12 further decreases to Ts (for example, 70 ° C.), the fan 42 is turned off, so that kitchen waste is removed. The drying operation is stopped, and the control by the control device 50 ends (steps 66 to 71).

In this embodiment, the main heater 1
In the switching of the heating ratio between the return heater 3 and the return heater 45, the driving of the main heater 13 is stopped, and only the return heater 45 is driven. Driving may be performed in a state of being reduced to the extent. Further, in the present embodiment, the switching of the heating ratio is performed once, but it is also possible to change the heating ratio a plurality of times by changing the heating ratio.

Further, according to the kitchen waste treatment machine of the present embodiment,
The gas cooled by the heat exchanger 22 of the condensing section 20 is supplied to the heating chamber 11.
A return pipe 41 for sending the gas to the garbage A is provided by forcibly circulating the gas in the closed space by the fan 42, so that a gas containing a large amount of water vapor generated by heating the garbage A flows into the heat exchanger 22, The gas cooled by the heat exchanger 22 and having a reduced water vapor content can be sent back to the heating chamber 11 again. Therefore, the water contained in the garbage A can be efficiently evaporated and the generated water vapor can be efficiently condensed, and the garbage disposal performance of the kitchen waste disposal machine can be enhanced.

Further, by using a simple structure in which the flow of gas from the condensed water discharge pipe 32 to the tank 31 is shut off by the water accumulated in the tank 31, an on-off valve such as a solenoid valve having a complicated mechanism is provided. The space including the heating chamber 11 and the condensing section 20 can be sealed from the outside without using a heat exchanger. Therefore, the kitchen waste disposal machine can be configured to be inexpensive and free from failure, and the water in the tank 31 is set at the set water level b.
Is flowed to the sewer pipe G, so that drainage can be performed while maintaining a closed space. In addition, since the pressure range in the sealed space can be adjusted by the water level difference between the condensed water discharge pipe 32 and the tank 31, it is possible to prevent a decrease in heating efficiency and leakage of odor components due to a high pressure in the sealed space. And the backflow of water from the tank 31 due to the low pressure can be prevented.

Further, since the garbage disposal machine is configured to condense water vapor generated from heated garbage A and drain it together with odor, it is possible to prevent odor leakage and increase in humidity, thereby preventing deterioration of the indoor environment. . Further, the heating chamber 11
Since the inside has a negative pressure, it is possible to prevent the odor from leaking from the gap with the lid 14 or the like, so that the sealing performance of the device is not unnecessarily increased, and the boiling point is lowered to dry at a low temperature. Since the treatment can be performed, power consumption required for heating can be reduced, and a rise in indoor temperature can be suppressed. Further, there is no need to provide an expensive device such as a vacuum pump to make the inside of the heating chamber 11 a negative pressure, and further, it is not necessary to provide a deodorizing device or a water vapor discharging device or the like. And the cost can be reduced.

Next, a second embodiment will be described. In the present embodiment, the change of the heating ratio of the main heater 13 and the return heater 45 is not performed after a lapse of a predetermined time from the start of the drying process described in the above-described embodiment. and, when the temperature of the processing tank 12 is equal to or higher than the temperature T _C of the provisions predetermined stops driving the main heater 13 is the only return heater 45 which was switched so as to drive. Processing tank 1
The temperature 2 is detected by the temperature sensor 16. Further, the portion of step 64 of the "drying process control program" executed by the control device 50 is changed to steps 64a and 64b as shown in FIG.

With the above configuration, the garbage in the vicinity of the wall of the processing tub 12 in the garbage stored in the processing tub 12 is sufficiently heated and dried, and the heat from the main heater 13 is efficiently applied to the garbage. not easily transmitted, the temperature treatment tank 12 is excessively heated rises above the predetermined temperature T _C, the temperature sensor 16
Detects this and outputs a signal (steps 64a and 64a).
4b). In response, control device 50 activates main heater 13
Is stopped, and switching control is performed so that only the return heater 45 is driven (step 65). As a result, the same effects as in the above embodiment can be obtained in this embodiment. In the present embodiment, regarding the temperature detection,
Instead of attaching the temperature sensor 16 to the wall surface of the processing tank 12, the temperature of the bottom of the processing tank 12,
1 The temperature of the atmosphere inside and outside may be detected.

In each of the above embodiments, an S-shaped pipe can be used as shown in FIG. 6 instead of the tank type drainage section. That is, the blocking drainage section 80 is provided with the fan 42 provided in the communication pipe 23 of the condensation section 20.
A down pipe section 81 connected to the high pressure side of the pipe to flow condensed water downward, and an up pipe section 82 which rises once from the down pipe section 81
And a discharge pipe portion 83 that communicates with the downstream sewer pipe G again from the upstream pipe section 82. Due to the siphon effect of the S-shaped pipe, the same operation and effect as those obtained by the above-mentioned block drainage section 30 can be obtained in the block drain section 80.

As for the main heater 13, a heating means such as a gas burner or a high frequency wave may be used instead. Further, in the present embodiment, the fan 42 is operated after a lapse of a predetermined time from the start of heating by the main heater 13, but is not limited to this. For example, the temperature in the heat exchanger 22,
The temperature of the treatment tank 12, the temperature, humidity, pressure, etc. in the heating chamber 11, or the water level in the cutoff drain section 30 may be detected, and the operation may be performed based on the detected values.
It may be operated simultaneously with the heating by the main heater 13. In addition, the kitchen waste processing machine shown in each of the above embodiments is merely an example, and can be implemented in various forms without departing from the gist of the present invention.
