Description

  The present invention relates to a garbage disposal machine used in general households.

  Currently, in household garbage processing machines, water vapor generated when heating and drying garbage is discharged to the outside of the garbage processing machine, that is, indoors, but odors and humidity make the room uncomfortable and cause condensation. There are problems such as. For this reason, a garbage processing machine has been proposed in which hot and humid air generated when heating and drying the garbage is cooled with cooling water, absorbed by condensing water vapor and odor, and not exhausted indoors.

  For example, in Patent Document 1, high-temperature and high-humidity polluted air generated by drying garbage in the decomposition tank is guided to the purification chamber, and brought into contact with water sprayed from a nozzle provided on the upper surface of the purification chamber. A garbage processing machine is disclosed that deodorizes and dehumidifies by adsorbing impurities therein and water vapor to water and then returning the deodorized tank to the decomposition tank. An electric water pump is provided as means for supplying water to the nozzle. As a result, a water circulation path of water tank → nozzle → purification chamber → water tank is formed.

  Moreover, in patent document 2, as shown to FIG. 1 and FIG. 5 of the literature, it dehumidifies from the warm air containing the water | moisture content which was supplied to garbage and finished drying, and supplies the warm air of low humidity to garbage again A water-passing dehumidifier is provided. This dehumidifying device is a system in which the air to be dehumidified and cooling water are in direct contact with each other, and the inside of the dehumidifying device is divided up and down by a vent plate made of a punching metal, and the inside is filled with cooling water. The dehumidified air is supplied from the lowermost part, and rises in the cooling water as many small bubbles when passing through the ventilation plate. At this time, moisture in the air to be dehumidified becomes condensed water and is absorbed by the cooling water to perform dehumidification. The cooling water is supplied from the inlet at the lower part of the apparatus and circulates to the outlet at the upper part of the apparatus.

JP 11-197634 A (paragraphs 0029 and 0034) Japanese Patent Laid-Open No. 7-313962 (FIGS. 1 and 5)

  In the techniques described in Patent Documents 1 and 2, by allowing the water vapor generated from the garbage to contact and absorb the cooling water, the garbage can be dried without exhausting a large amount of moisture and odor into the room.

  However, when spraying cooling water as in Patent Document 1, there is a problem that the apparatus becomes large in order to secure a space in which the cooling water is sprayed. Further, in order to atomize the cooling water, it is necessary to apply a water pressure at the inlet of the nozzle, and an electric water pump as disclosed in Patent Document 1 is necessary, and accordingly, the entire apparatus becomes complicated and large. At the same time, there is a problem that power consumption increases. Further, although impurities are sterilized by ozone gas, there is a problem that the water containing impurities circulates through the circulation channel including the water tank at all times and is not hygienic.

  In addition, in the method in which high-temperature and high-humidity air is sent from the lower part of a container filled with cooling water as in Patent Document 2, it is possible to reduce the size of the whole garbage disposal apparatus by configuring the dehumidifier in a flat plate shape. Since the liquid head from the liquid level of the cooling water to the lower part of the container is hung on the supply unit, it is necessary to increase the pressure of air to a pressure higher than that of this head, requiring a large amount of fan power and increasing power consumption. There are challenges. Further, this method is unsanitary because the cooling water that absorbs odorous components and the like always stays in the apparatus, which may cause a bad odor. Therefore, it is an object to provide a dry-type garbage processing machine that suppresses the increase in the size of the apparatus and the increase in power consumption, and does not require indoor exhaust, and does not emit odors and moisture, and the garbage is dried. .

  In order to solve the above-mentioned problems, the present invention is to cool a part of high-temperature and high-humidity air generated during the drying process of garbage on a vertical wall surface on which a liquid film is formed by naturally flowing cooling water on the surface. A dry-type garbage treatment machine equipped with water-cooled dehumidifying means for contacting water was used.

  ADVANTAGE OF THE INVENTION According to this invention, the dry-type garbage processing machine which suppresses the enlargement of an apparatus and the increase in power consumption, and dry-processes garbage without exhausting indoors is obtained.

  In addition, because the cooling water that has adsorbed impurities and water vapor is drained to the sewage system, it is possible to avoid the emission of bad odors and moisture into the room, and to keep the inside of the dry garbage processing machine hygienic. .

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is an overall system diagram of a dry-type garbage processing machine according to the present invention, and FIG. 2 is a system diagram of circulating air in the drying processing section.

  FIG. 2 is a diagram for explaining a drying processing unit including a drying container 3, an air circulation fan 4, an air heater 5, a deodorizing device 6, a water-cooled dehumidifying device 7, and the like. In this drying processing unit, the high-temperature and high-humidity air A1 is discharged from the drying container 3, and the high-temperature and high-humidity air A1 is branched into A2 that goes to the water-cooled dehumidifier 7 and A3 that bypasses the water-cooled dehumidifier 7. Although not shown in the figure, an electric stirring blade is installed inside the drying container 3.

  The water-cooled dehumidifier 7 is connected to the outlet of a flow rate adjusting valve V that is connected to the clean water and adjusts the flow rate of the cooling water. Inside the water-cooled dehumidifier 7, a water-cooled dehumidifying plate having meandering ribs 71 provided on a vertical wall surface is provided. A cooling water outlet is provided at the lower part of the apparatus, and this outlet is connected to a sewage system.

  Further, a circulating air outlet is provided at the lower part of the water-cooled dehumidifying device 7, and this circulating air A4 merges with the circulating air A3 that bypasses the water-cooled dehumidifying device 7 to become the circulating air A5. Led to the side. The circulation air outlet of the air circulation fan 4 is connected to the air heater 5.

  The air heater 5 is an electric heater in which a heating wire 51 is provided. The outlet air A7 of the air heater 5 is branched into A8 that goes to the deodorizing device 6 and A9 that bypasses the deodorizing device 6. A deodorizing heater 6 h is provided at the air inlet of the deodorizing device 6. The deodorizing device 6 has a catalyst supported on a honeycomb-shaped surface, and has a property that the deodorizing effect increases as the temperature of the air increases.

  The outlet air A11 of the deodorizing device 6 is led to the drying container 3 together with the circulating air A9 bypassing the deodorizing device 6. The joined air duct is provided with a temperature sensor T1 for measuring the hot air temperature.

  The operation of the dry garbage processing machine configured as described above is as follows. First, garbage is thrown into the disposer 1 opened in the sink 10 such as a kitchen. It should be noted that a protective lid is installed at the garbage input port 11 when the garbage processor is not used. In the disposer 1, the raw garbage thrown in by the crushing hammer rotating inside is crushed. During the crushing of garbage, tap water is supplied to the disposer to promote crushing and convey the crushed garbage to the solid-liquid separator 2.

  In the solid-liquid separator 2, the crushed garbage and the tap water used for conveyance are separated into solid and liquid, and the liquid portion separated from the garbage is drained from the drain pipe 21 to the sewage system. On the other hand, the solid part of the garbage which has been subjected to solid-liquid separation is put into the drying container 3 by natural fall.

  In the drying container 3, the input garbage is dried by hot air A12 while being stirred by a stirring blade omitted in the drawing. At this time, water vapor and odor components are separated from the garbage and generated, and together with the hot air whose temperature has been reduced, the hot and humid air A1 is discharged from the drying container 3. The hot and humid air A1 is branched into two, A2 and A3, by the air circulation duct, and A2 is led to the water-cooled dehumidifier 7.

  In the water-cooled dehumidifier 7, the cooling water W <b> 2 is supplied to the surface of a water-cooled dehumidifying plate in which a rib 71 is provided on a wall surface installed substantially vertically. The cooling water W2 is obtained by adjusting the flow rate and depressurizing the tap water W1 supplied from a pipe directly connected to the tap water with the flow rate adjusting valve V. The cooling water W2 forms a falling liquid film on the water-cooled dehumidifying plate, and flows down while meandering the surface of the plate by the ribs 71.

  The high-temperature and high-humidity air A2 guided to the water-cooled dehumidifier 7 is cooled in contact with the cooling water that forms a falling liquid film inside the water-cooled dehumidifier 7, and is one of water vapor and odor components generated in the drying container 3. Part is condensed and absorbed at the interface with the cooling water. The high-temperature and high-humidity air A <b> 2 becomes the circulating air A <b> 4 with reduced humidity and reduced odor components, and is discharged from the water-cooled dehumidifier 7. On the other hand, the cooling water that has absorbed the water vapor and the odor component rises in temperature due to the latent heat of the water vapor and becomes drainage W3, which is led to the drain pipe 21 and drained into the sewage system.

  The circulating air A4 joins with the hot and humid air A3 bypassing the water-cooled dehumidifier 7 to become the circulating air A5, and is pressurized and blown by the air circulating fan 4 to become the circulating air A6, which is led to the air heater 5. The air heater 5 is an electric heater 51 provided with a heating wire 51 therein, and the circulating air A6 is heated by the electric heater 51 to become high-temperature circulating air A7.

  The high-temperature circulating air A7 branches into A8 guided to the deodorizing device 6 and A9 bypassing the deodorizing device 6. The high temperature circulating air A8 is further heated and guided to the deodorizing device 6 by the deodorizing heater 6h, and the odor component is decomposed by the nano platinum catalyst supported on the honeycomb-shaped surface. The deodorized high-temperature circulating air A11 joins with the high-temperature circulating air A9 that bypasses the deodorizing device 6, becomes hot air A12 for drying, and is supplied to the drying container 3 again.

  As described above, the high-temperature and high-humidity air that has come out of the drying container 3 is deodorized and dehumidified while returning to the circulating air flow path including the water-cooled dehumidifying device 7, and returns to the drying container 3 as dry air. Moreover, the cooling water which absorbed the water vapor | steam and odor component discharged | emitted from the water-cooling type dehumidifier 7 is drained by a sewer system.

  The result of the garbage drying operation by a present Example is shown in FIG. FIG. 3 shows the temperature sensor T1 of hot air A12 when a standard garbage of about 700 g, which is a standard amount of garbage generated for a family of four, is processed by the dry garbage processing machine according to this embodiment. It is the result of actual measurement and the result of actual measurement of the hot and humid air A1 discharged from the drying container 3. Both temperatures change at a substantially constant value during the drying operation, and the temperature rises when the end of drying is near. Therefore, the end of drying can be determined from this temperature trend, and the heating and drying operation can be stopped.

  In addition, when the garbage processed after the drying operation of FIG. 3 was confirmed, the condition of drying was good and the weight was reduced from about 700 g to about 25 g. This confirmed the effectiveness of the present invention.

  As described above, in the present embodiment, the water-cooled dehumidifier 7 is used as the moisture discharging means of the dry-type garbage disposal machine, and the indoor comfort is maintained by eliminating the need for exhausting outside the garbage disposal machine, that is, indoors. is doing. Furthermore, this water-cooled dehumidifier 7 forms a falling liquid film by flowing cooling water on a vertical wall surface, and the hot and humid air from the drying container 3 and the cooling water are in direct contact with the surface of the falling liquid film. Therefore, the water-cooled dehumidification device is thinner than the spray method and the bubble generation method, and the entire dry garbage treatment machine can be made compact.

  Further, in this embodiment, by supplying the cooling water W1 as a direct water supply type, a pump for supplying and circulating the cooling water becomes unnecessary, so that the entire apparatus is reduced in size, simplified in structure, and related to the pump. This makes it possible to avoid malfunctions such as malfunctions and water leaks, and avoid power consumption increase due to pump power.

  Further, in this embodiment, the cooling water is naturally flowed down and the dehumidified air is sucked by the dry air blower fan in the water-cooled dehumidifying device 7, so that the head for spraying the cooling water as in Patent Document 1 is used. And a fan that requires higher pressure and suction force than the full liquid type liquid head as in Patent Document 2 are not required, the working fluid transfer power is reduced, and the power consumption of the entire apparatus is reduced. ing.

  Furthermore, in this embodiment, since the water-cooled dehumidifying device 7 is a falling liquid film type, the odor component sticks to the inner surface of the container by spraying the cooling water as in Patent Document 1, or the cooling is performed as in Patent Document 2. A sanitary garbage disposal machine that can avoid rot and decay of odor components due to the retention of water and does not generate malodors or microorganisms has been realized.

  Further, in the present embodiment, the hot and humid air A1 from the drying container 3 is branched, a part is discharged to the water-cooled dehumidifier 7 and the rest is discharged from the water-cooled dehumidifier 7 by bypassing the water-cooled dehumidifier 7. Circulated into the circulating air A4. At this time, when the entire amount is passed through the water-cooled dehumidifier 7, a substantial portion of the cooling water is used for sensible heat cooling, and the dehumidifying ability cannot be sufficiently exhibited. In this embodiment, by branching the high-temperature and high-humidity air A1, an appropriate amount is guided to the water-cooled dehumidifier 7 so that the dehumidifying performance of the water-cooled dehumidifier 7 is sufficiently exhibited, and the dehumidifying effect is improved and the operation time is improved. The power consumption of the heater etc. is reduced.

  Furthermore, in this embodiment, both the water-cooled dehumidifying device 7 and the deodorizing device 6 using the catalyst are provided as means for deodorizing the circulating air. By decomposing and deodorizing the odor component with the deodorization device 6, the deodorization effect is improved corresponding to various odor components.

  Further, in this embodiment, the air heater 5 for heating and drying garbage is provided between the water-cooled dehumidifying device 7 and the deodorizing device 6, so that the temperature of the air supplied to the deodorizing device 6 is increased and the deodorizing is performed. The deodorizing ability of the device 6 is improved. In this embodiment, the deodorizing heater 6h is provided at the inlet of the deodorizing device 6. However, since the inlet air temperature of the deodorizing heater 6h is increased in advance by the air heater 5, the power consumption of the deodorizing heater 6h is reduced. Has been. In addition, although the structure which provides the heater for exclusive use of a deodorizing which heats the whole quantity of the to-be-deodorized air led to this catalyst deodorizing apparatus in the upstream of a catalyst deodorizing apparatus is a well-known technique, in this Example, it is for garbage drying. A point where the air heater 5 is provided upstream, a part of the circulation air A7 for drying heated by the air heater 5 is branched and reheated by the deodorizing heater 6h provided at the inlet of the deodorizing device 6. Is a feature.
