Moreover, FIG. 3 shows the garbage processing method of this garbage processing apparatus. Further, FIG. 4 shows an electrical block configuration of the garbage disposal apparatus, FIG. 5 shows a cross section of the garbage disposal apparatus, and FIG. 6 shows a use state of the garbage disposal apparatus.

  A garbage disposal apparatus 1 according to an embodiment of the present invention includes a reaction chamber 20 that accommodates garbage and a main body 3 that includes a compressor 10 that compresses a refrigerant, and is connected to the compressor 10. A drying means for drying the garbage using heat generated by driving the compressor 10, a condensation means provided on one side of the drying means for condensing water vapor evaporated from the garbage, and a condensing means. And storage means for collecting and storing condensate that is connected and condensed with water vapor.

  The compressor 10 has a function of compressing the refrigerant in the compressor 10 to a high temperature and a high pressure. The high-temperature and high-pressure refrigerant compressed by the compressor 10 moves to the reaction chamber 20 through a pipe connected to the compressor 10 due to the pressure generated in the compressor 10.

  The reaction chamber 20 is where the collected garbage is dried, and a drying unit and a condensing unit are provided in the reaction chamber 20. In addition, a garbage tray 20a can be disposed in the reaction chamber 20 so as to facilitate collection and transportation of the garbage. The garbage tray 20a can be manufactured in various forms depending on the embodiment.

  The drying means is for drying garbage collected in the reaction chamber 20, and includes a garbage tray 20 a, a first heating unit 21, an electric heating plate 23, a second heating unit 30, and the like. And the first circulation fan 40.

  The first heating unit 21 is for primarily drying the collected garbage, and is provided in the lower part of the reaction chamber 20. The first heating unit 21 raises the temperature in the reaction chamber 20 using the heat of the high-temperature refrigerant compressed by the compressor 10, and the garbage in the reaction chamber 20 is dried by such a rise in temperature. .

  The electric heating plate 23 is for heating the garbage uniformly, and is provided on the upper portion of the first heating unit 21. The electric heating plate 23 converts electric power into heat and generates heat. Due to the heat generated by the electric heating plate 23, the garbage is uniformly heated, and the garbage can be dried uniformly.

  The second heating unit 30 is connected to the first heating unit 21 and increases the temperature of the reaction chamber 20 using the refrigerant that has passed through the first heating unit 21, and is provided on the inner wall of the reaction chamber 20. . Specifically, the refrigerant passing through the second heating unit 30 has a lower temperature and pressure than the refrigerant passing through the first heating unit 21 but has a temperature sufficient to increase the temperature of the reaction chamber 20. Therefore, the temperature of the reaction chamber 20 is increased.

  The first circulation fan 40 forcibly stirs the air in the reaction chamber 20, and the garbage in the reaction chamber 20 whose temperature is increased by the first heating unit 21 and the second heating unit 30. The hot water vapor evaporated from is forced to stir. Since the water vapor stirred by the first circulation fan 40 keeps the temperature in the reaction chamber 20 uniform, more efficient drying is performed. Further, the stirred water vapor moves to the condensing means in the upper part of the reaction chamber 20 due to the density difference.

  The condensing unit condenses the water vapor generated by the drying unit, and includes a cooling unit 50 and a condensed water tray 53.

  The cooling unit 50 cools and condenses high-temperature water vapor to generate condensed water, and the refrigerant that has passed through the third heating unit 60 and the capillary tube 51 described later is transferred to maintain a low-temperature state. It is supposed to be. The refrigerant transferred to the cooling unit 50 passes through the first heating unit 21, the second heating unit 30, and the third heating unit 60, is transferred to the capillary 51 in a low temperature / low pressure state, and then the capillary 51 Passing through, the volume expands to a lower temperature. Therefore, the cooling unit 50 is in a low temperature state, lowers the temperature of the high temperature water vapor, and thus condenses the water vapor to generate condensed water.

  The cooling unit 50 is made of copper having antibacterial, deodorizing, and detoxifying functions in order to remove malodors generated from high-temperature water vapor, and the water vapor has been deodorized by such a cooling unit 50. It is condensed with. In the present embodiment, the cooling unit 50 is made of copper, but it is also possible to manufacture the cooling unit 50 using platinum, palladium, rhodium, or the like that has antibacterial, deodorizing, and detoxifying functions.

  The condensed water tray 53 collects the condensed water condensed by the cooling unit 50 and is provided at the lower part of the cooling unit 50. The condensed water collected in the condensed water tray 53 is discharged to a storage means outside the reaction chamber 20 through a drain pipe 55 connected to the lower part of the condensed water tray 53. As described above, the reaction chamber 20 is for drying raw garbage and condensing water vapor generated during drying. Therefore, the reaction chamber 20 should desirably be sealed so that malodors resulting from the drying and condensation processes do not flow out of the garbage disposal apparatus 1.

  The storage means is formed on one side of the main body 3, stores the condensed water condensed by the condensing means, and evaporates it to the outside of the main body 3. The storage means 55, the evaporating tray 61, the third heater And a drier 63.

  The water distribution pipe 55 discharges condensed water collected in the condensed water tray 53 to the outside of the reaction chamber 20, and is connected to the lower part of the condensed water tray 53. The evaporating tray 61 collects condensed water discharged through the drain pipe 55 and is provided at a lower portion on one side of the main body 3.

  The third heating unit 60 evaporates the condensed water collected on the evaporation tray 61, and is provided on the evaporation tray 61. The third heating unit 60 is connected to the second heating unit 30 and evaporates the condensed water collected in the evaporation tray 61 using the heat of the refrigerant that has passed through the second heating unit 30. Yes.

  The dryer 63 is for removing moisture and foreign matter contained in the refrigerant, and is connected to the third heating unit 60. When the refrigerant contains moisture and foreign matter, the performance of the compressor 10 may be inferior, so the dryer 63 is connected to the pipe that has passed through the third heating unit 60, and the moisture contained in the refrigerant. In addition, foreign matter is removed by the dryer 63.

  Further, since there is heat also in the refrigerant that has passed through the dryer 63, the dryer 63 is provided in the evaporation tray 61 so that the condensed water in the evaporation tray 61 can be evaporated using this heat. Accordingly, the condensed water discharged to the evaporation tray 61 is heated and evaporated by the refrigerant that has passed through the third heating unit 60 and the dryer 63. The water vapor evaporated by the third heating unit 60 and the dryer 63 is discharged to the outside of the main body 3 through a water vapor discharge port 65 formed on one side of the main body 3.

  The garbage disposal apparatus 1 includes a second circulation fan 70, a first temperature sensor 57, a second temperature sensor 41, a controller 80, and an air duct 66.

  The second circulation fan 70 is for adjusting the amount of heat generated by the third heating unit 60, and is provided in the third heating unit 60. The 1st temperature sensor 57 measures the temperature of the cooling unit 50, and is provided in piping at the exit side of the cooling unit. The second temperature sensor 41 measures the temperature of the reaction chamber 20 and is provided in a pipe on the outlet side of the second heating unit 30.

  When the temperature of the refrigerant that has passed through the third heating unit 60 is high, the cooling unit 50 connected to the third heating unit 60 cannot maintain sufficient cooling performance. On the contrary, when the temperature of the refrigerant that has passed through the third heating unit 60 is low, the temperature in the reaction chamber 20 is low, so that the garbage cannot be dried.

  Therefore, in order to prevent overload of the compressor 10 and to keep the temperature in the reaction chamber 20 constant, the second temperature sensor 41 that senses the temperature of the second heating unit 30 is provided in the second heating unit 30. Provided in the piping on the outlet side, receives the signal of the second temperature sensor 41, and controls the second circulation fan 70 by the controller 80 to adjust the heat generation amount of the third heating unit 60.

  In addition, a first temperature sensor 57 for measuring the dry state of the garbage is provided in the piping on the outlet side of the cooling unit 50, and the dry state of the garbage is measured in response to a signal from the first temperature sensor 57. When the drying of the garbage is completed, the controller 80 shuts off the power supply of the compressor 10.

  At this time, the dry state of the garbage can be measured as follows. Since the garbage during drying still contains moisture, it can generate water vapor, but the dried garbage does not generate any more water vapor. Therefore, when the drying is completed, the water vapor flowing into the cooling unit 50 does not exist, and thereby the temperature of the cooling unit 50 shows a change. The temperature change is measured by the first temperature sensor 57 to measure the dry state of the garbage, and the controller 80 controls the driving of the compressor 10.

  Further, in order to manually operate the controller 80, a display 83 linked to the controller operation switch 81 and the controller 80 is provided on the front surface of the garbage disposal apparatus 1.

  The air duct 66 is for discharging water vapor evaporated from the condensed water of the evaporation tray 61 to the outside of the main body 3 through the water vapor discharge port 65, and is coupled to the water vapor discharge port 65. The air duct 66 includes a blower fan 67 for forcibly flowing out the water vapor generated from the evaporation tray 61 to the outside of the garbage disposal apparatus 1. The driving of the blower fan 67 is controlled by a controller 80 to which the first temperature sensor 57 and the second temperature sensor 41 are connected.

  A garbage disposal method of the garbage disposal apparatus 1 configured as described above will be described with reference to FIG.

  First, the change of the refrigerant will be mainly described. The low-temperature gaseous refrigerant is compressed by the compressor 10 to be in a high temperature / high pressure state, and the first heating unit 21, the second heating unit 30, and the third heating unit 60 are changed. While passing, it becomes a state of medium temperature and medium pressure. The refrigerant in the intermediate temperature / intermediate pressure state passes through the dryer 63 in order to remove moisture and foreign matters contained in the refrigerant, then passes through the capillary 51 to become a low temperature / low pressure state, and passes through the cooling unit 50. In addition, the refrigerant that has passed through the cooling unit 50 moves to the compressor 10 after being in a low temperature / low pressure state.

  In this process, malodor and water vapor that can be generated from garbage are treated as follows. When the garbage is stored in the reaction chamber 20, the temperature of the reaction chamber 20 rises due to the heat generated from the first heating 21 and the heat generated from the second heating unit 30, and thus stored in the reaction chamber 20. Garbage is dried.

  The high-temperature water vapor generated from the drying process moves to the cooling unit 50 due to the density difference, and is condensed inside the cooling unit 50 to become condensed water. At this time, since the cooling unit 50 is made of copper or the like having a deodorizing function, the malodor contained in the transferred water vapor is removed, and the water vapor from which the malodor is removed is condensed to be condensed water. The condensed water is discharged to the evaporation tray 61 through the drain pipe 55.

  The condensed water discharged to the evaporating tray 61 is changed to water vapor again by the third heating unit 60 and the dryer 63 and is discharged to the outside through the water vapor outlet 65. Garbage that has undergone such a process is in a state where moisture has been removed, and can be reduced to 80 to 90% of the original bulk volume.

  As shown in FIG. 5, the coating layer is provided on the inner surface of the main body 3 of the garbage processing apparatus 1 so that malodors generated when the garbage is dried and water vapor generated from the evaporation tray 61 do not flow out of the main body 3. 5 is desirable.

  Further, a filter 68 for removing the bad smell of water vapor evaporated from the condensed water in the evaporation tray 61 may be assembled in the air duct 66. As the filter 68, a photocatalytic filter having an antibacterial and deodorizing function, a carbon filter, a silver nanofilter, or the like can be used.

  Further, as shown in the use state diagram of FIG. 6, by connecting a duct (not shown) of the gas range hood and the air duct 66 with a duct connecting pipe 100, water vapor generated from the garbage disposal apparatus 1 is converted to the duct of the gas range hood. Can be discharged.

  Another embodiment of the present invention will be described with reference to FIG. Moreover, in the figure, the same code | symbol is attached | subjected to the same structural member as embodiment mentioned above.

  The other embodiment illustrated in FIG. 7 includes heat radiation fins 31 for increasing the heat transfer efficiency of the second heating unit 30 and the third heating unit 60. According to this embodiment, the radiating fin 31 expands the cross-sectional areas of the second heating unit 30 and the third heating unit 60, so that the drying time can be shortened.
