  However, in the case of such a garbage processing machine, for example, if there is no input of garbage over a long period of time, the microorganisms involved in the decomposition itself will not be consumed for maintenance, and drying will proceed and the next garbage will be collected. When it was thrown in, there was a problem that it was difficult to start decomposition, or that it consumed more power than necessary to contribute to the decomposition of garbage.

  The present invention solves the above-described problem, and is a garbage disposal machine that is easy to use and can provide good decomposition and drying performance according to any usage environment even in intermittent usage. Is realized.

  In order to solve the above-mentioned conventional problems, the garbage processing machine of the present invention is to set the temperature of the treatment tank to a temperature near the freezing point and slightly higher than the freezing point, unless there is no garbage input over a long period of time. As a result, it is possible to provide an easy-to-use garbage disposal machine that can reduce power consumption even when no garbage is thrown in, and that can exhibit the decomposition performance more quickly when the garbage is recharged.

  The present invention realizes an easy-to-use garbage processing machine that can exhibit the decomposition performance more quickly when the garbage is re-introduced even if the garbage is not input for a long period of time.

  The first invention is provided with a low processing mode in which the temperature of the treatment tank is lowered when the garbage input detection means does not detect the input of garbage exceeding a predetermined time, and the temperature is higher than near the freezing point. Therefore, even if no garbage is input for a long period of time, it is possible to realize an easy-to-use garbage processing machine that can exhibit the decomposition performance more quickly when the garbage is re-input.

  The second aspect of the present invention provides a low-treatment mode in which the operation of the agitation means is reduced from the normal time when the waste input detection means does not detect the input of the garbage over a predetermined time, so that the garbage input over a long period of time. Even if there is no waste, it is possible to realize an easy-to-use garbage processing machine that can exhibit the decomposition performance more quickly when the garbage is re-introduced, according to all usage environments.

  According to a third aspect of the present invention, there is provided a low processing mode in which the operation of the ventilation fan is interrupted or kept at a low rotation speed when the garbage input detection means does not detect the input of garbage for a predetermined time, thereby suppressing the operation over a long period of time. Even if no garbage is thrown in, it is possible to realize an easy-to-use garbage disposal machine that can exhibit the decomposition performance more quickly when the garbage is thrown in again, according to all usage environments.

  According to a fourth aspect of the present invention, there is provided a humidity detecting means for detecting the humidity in the processing tank, and the low processing mode is not entered until the humidity in the processing tank becomes lower than the predetermined humidity. Even if there is no garbage input, when the humidity in the treatment tank is high and sufficient drying is not progressing, do not enter the low treatment mode, operate normally, and maintain the dry decomposition performance of the garbage in the treatment tank. As a result, an easy-to-use garbage disposal machine with stable performance can be realized.

  According to the fifth aspect of the present invention, by detecting the opening and closing of the lid as garbage input detection means for detecting the input of garbage, it is possible to detect the introduction of garbage more easily and automatically. A good garbage disposal machine can be realized.

  According to a sixth aspect of the present invention, by providing a low processing mode in which the operation of the ventilation fan is stopped when the garbage input detection means does not detect the input of garbage over a predetermined time, the substrate of the processing tank is overdried. This makes it possible to realize an easy-to-use kitchen garbage disposal machine that can exhibit its decomposition performance more quickly when waste is re-introduced, according to all usage environments.

  According to the seventh aspect of the present invention, it is possible to know that the user is operating in the low processing mode by notifying that the user is operating in the low processing mode by a lamp display or the like. It is possible to pay attention to the load, and it is possible to realize an easy-to-use garbage disposal machine with more stable performance.

  According to an eighth aspect of the present invention, in the low processing mode, immediately after the garbage input detecting means detects the input of the garbage, or after the predetermined time has elapsed, the low processing mode is canceled to re-input the garbage. After a certain period of time has elapsed since the start of re-injection, or after a sufficient period of decomposition performance has been restored, the substrate is restored from the low processing mode, preventing over-drying of the substrate at the initial stage of re-injection, and more stable performance. A user-friendly garbage disposal machine can be realized.

  The ninth aspect of the invention can alert the user that the user has returned from the low processing mode, or is in the process of returning, so that the user can pay attention to overload when throwing in the garbage. An easy-to-use garbage disposal machine with more stable performance can be realized.

  The tenth invention is in the low processing mode, and when the humidity in the processing tank detected by the humidity detecting means exceeds a predetermined value or rises to a predetermined value or more, a device is notified by a lamp display or the like. This makes it possible to inform the user of the abnormalities and to realize an easy-to-use garbage disposal machine with more stable performance.

  The eleventh aspect of the invention is in the low processing mode, and stops the operation of the ventilation fan while the stirring means is stirring or for a predetermined time after the stirring is stopped. Even in such a case, it is possible to realize an easy-to-use garbage disposal machine with little equipment discharge.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. Note that the present invention is not limited to the embodiments.

(Embodiment 1)
A first embodiment of the present invention will be described with reference to FIGS.

  FIG. 1 is a sectional view of a garbage disposal main unit 1 (hereinafter referred to as a main unit) according to a first embodiment of the present invention.

  The treatment tank 2 includes a base material A (hereinafter referred to as a base material) made of “microorganism carrier such as garbage and sawdust” and has a lid 3 on the upper side. Can be done. The lid 3 is provided with a lid detection switch 4 for detecting the opening of the lid. The processing tank 2 is provided with a stirring means 5 for stirring the base material A, and is rotated by a motor such as a motor to perform a base material stirring operation for stirring the base material A. A heating means 6 composed of a resistance heater or the like and a temperature sensor 7 for detecting the temperature of the processing tank 2 are attached to the outer wall of the processing tank 2, and the processing tank 2 is heated as necessary to form a base material in the processing tank 2. A is maintained at a predetermined temperature. An intake passage 8 and an exhaust passage 9 communicating with outside air are connected to the processing tank 2, and a ventilation fan 10 that blows air from the processing tank 2 toward the outside air is provided in the exhaust passage 9. Further, a humidity detecting means 15 for measuring the humidity in the processing tank 2 is attached to a part of the processing tank 2.

  The lid detection switch 4, the stirring means 5, the heating means 6, the temperature sensor 7, the ventilation fan 10, the warm air heater 12 and the intake fan 13, the outside air temperature sensor 14, and the humidity detection means 15 are all connected to the control device 16. .

  The operation of the garbage disposal machine configured as described above will be described.

  FIG. 2 is a flowchart showing the operation of this garbage disposal machine. First, a normal processing operation will be described. The garbage processing machine by the microorganism usually performs continuous garbage processing. Therefore, the processing tank 2 is always kept at a predetermined temperature T0 by the temperature sensor 7 and the heating means 6 by the control device 16 (S0001) and continuously stirred intermittently by the stirring means 5 (S0002). ). At the same time, the ventilation fan 10 is continuously operated (S0003).

  When the user opens the lid 3, the control device 16 stops the stirring means 5 by a signal from the lid detection switch 4 (S0004) (S0005). Subsequently, when the user throws the garbage to be treated into the treatment tank 2 (S0006) and closes the lid 3, the lid detection switch 4 detects the opening / closing of the lid 3, that is, the introduction of the garbage, and the control device 16 (S0007).

  When the opening / closing of the lid 3 is detected by the lid detection switch 4, the control device 16 performs a preliminary drying operation for a predetermined time thereafter (S0008). Meanwhile, if necessary, the hot air heater 12 is also operated simultaneously (S0009). Garbage thrown in by this preliminary drying process loses a certain amount of water by evaporation, and the evaporated water is discharged to the outside air simultaneously with the exhaust through the exhaust passage 9 (S0010). After elapse of a predetermined time (S0011), the control device 16 stops the warm air heater 12 (S0012) and the intake fan 13 (S0013).

  Thereafter, the control device 16 keeps the treatment tank 2 at a predetermined temperature by the temperature sensor 7 and the heating means 6 (S0001) and is stirred intermittently by the stirring means 5 (S0002). At the same time, the ventilation fan 10 is continuously operated (S0003).

  Now, when the opening of the lid 3 of the lid detection switch 4 is detected (S0007), it is detected that the garbage is thrown in (S0101). Thereafter, when the lid 3 is closed and the lid detection switch 4 detects the closure of the lid 3, the closing interval timer tm is reset (S0102), and thereafter the addition of the closing interval timer tm starts (S0103). The process proceeds as described above, and during that time, the insertion interval timer tm is added until the opening / closing detection of the lid 3 is detected (S0007), and the time is measured.

  The insertion interval timer tm is continuously evaluated in the process (S0104), and when the predetermined time ts is exceeded, the low processing mode is entered (S0105).

  In the low processing mode, the control target temperature T0 of the processing tank 2 is decreased (S0106). Then, the operation of the stirring means 5 is reduced more than usual (S0107). In addition, the operation of the ventilation fan is interrupted or suppressed to low rotation (S0108). These low processing modes continue until the lid detection switch 4 detects the opening of the lid 3 (S0109), and at the same time, the normal control target temperature T0, the normal stirring means 5 operation, and the normal ventilation fan operation. Return to (S0110).

  Now, the above low processing mode will be described in detail. The control target temperature T0 is the type of garbage processing machine that decomposes garbage with microorganisms. When the garbage is continuously input, the microorganisms are activated actively when the decomposition is continued, and the evaporation of moisture occurs. It is set above normal temperature (30 ° C or higher).

  In the low processing mode, the control target temperature T0 is set to about 5 ° C. This is a temperature set to maintain the entire base material A at a temperature exceeding at least the freezing point (0 ° C.). When used in an environment where the outside air temperature is very low, the substrate A freezes when the substrate A falls below freezing point (0 ° C.). When the base material A is frozen, it will take a lot of time for the microorganisms of the base material A to start moving when the next garbage is put in. In addition, because the moisture inside the garbage that is not originally released by freezing is freed by freezing, when the garbage is thrown in and the temperature in the treatment tank 2 rises, the frozen moisture is melted at one time and processed. A region in which the surface and the inside of the tank 2 are locally excessively watery and air does not enter easily occurs. Anaerobic fermentation becomes active in a state where there is too much water and no air enters, so a strong odor may be emitted. This can be prevented in advance by maintaining the substrate A at a freezing point (0 ° C.) or higher. As a result, the generation of malodor associated with anaerobic fermentation can be prevented, and a more convenient kitchen garbage processing machine can be realized.

  Further, in the low processing mode, the operation of the stirring means 5, for example, the timing of stirring is extremely reduced compared with the normal time, and stirring is performed at intervals of several times a day. In this way, by taking an interval at least twice that of normal time, the base material A is prevented from being dried and crushed more than necessary. It is possible to shift to a good state.

  In the present invention, stirring is not completely stopped. Since the agitation is not completely stopped, the minimum intake performance is ensured even during the low processing mode. As a result, the generation of malodor associated with anaerobic fermentation can be prevented, and a more convenient kitchen garbage processing machine can be realized.

  Further, in the low processing mode, the operation of the ventilation fan 10 is interrupted or suppressed to a low rotation as compared with the normal time. As a result, the amount of ventilation that circulates is reduced. For example, when the amount of ventilation that circulates when the outside air is at a low temperature, the temperature inside the treatment tank 2 can be easily maintained, and the power consumption for maintenance is also suppressed. At the same time, the diffusion of moisture is suppressed and it becomes difficult to become overdried.

  However, when the ventilation fan 10 is completely turned off and stopped, it is good in terms of drying and power consumption. However, since it is difficult for air to enter the base material A, anaerobic fermentation is performed without air. As a result, it becomes possible to prevent the generation of malodor associated with anaerobic fermentation, and to realize a more convenient garbage processing machine.

  The humidity H in the processing tank 2 is always measured during normal operation (S0201). However, when the above-described charging interval timer tm exceeds a predetermined time ts (S0105), the humidity H is a predetermined humidity. If it exceeds Hs, that is, if the humidity is higher than necessary, the low processing mode is not entered and the operation is continued as it is (S0202).

  That is, when the humidity is higher than necessary even after the predetermined time ts has elapsed, it is assumed that the substrate A still has sufficient moisture, or there is an undecomposed product in the middle of decomposition, and the low processing is performed as it is. When moving to the mode, there is too much moisture, and as a result, anaerobic fermentation that does not allow air to enter becomes active, resulting in a strong odor. The present invention does not emit such a strong odor.

  In addition, the input of garbage is detected by detecting the opening and closing of the lid, and it is possible to detect the introduction of garbage more easily and automatically. It can be realized.

  Further, when the above-described stirring is not completely stopped and the exhaust passage 9 provided with the ventilation fan 10 has a passage communicating with the outside air even when the ventilation fan 10 is stopped, the ventilation fan 10 is temporarily Even if the operation is completely stopped, moisture by stirring is discharged out of the machine body due to the diffusion effect, so that an appropriate air flow can be ensured as in the case described above, and stable performance can be ensured.

  FIG. 4 is an external view of a part of the lid 3 of the garbage disposal machine according to the embodiment of the present invention. On the surface of the lid 3, a low processing mode display lamp 17 that is visible from the outside is disposed. A warning display lamp 18 is further arranged on the surface of the lid 3.

  This display lamp 17 is used to indicate to the user by lighting that the process of the main body is in a state corresponding to one of the low processing modes described above. As a result, the user can know the state of the garbage processing machine, and can adjust the amount of waste input again in accordance with the state, which helps to obtain more stable performance.

  Immediately after the garbage input detection means detects the introduction of garbage, or after a predetermined time has elapsed, the low processing mode is released, so that after a certain period of time has elapsed after the garbage has been re-introduced or reintroduced. By returning from the low processing mode after sufficient disassembly performance has been restored, it is possible to prevent over-drying of the base material at the initial stage of re-input, and to realize an easy-to-use garbage disposal machine with more stable performance. is there.

  In addition, by using the display lamp 17 to notify the user that the user has returned from the low processing mode or is in the process of returning, the user may be careful about overload when throwing in the garbage. It is possible to realize an easy-to-use garbage disposal machine with more stable performance.

  Now, when in the low processing mode, the humidity H in the processing tank 2 is measured by the humidity detecting means 15 (S0301), and when the predetermined value is exceeded or rises above the predetermined value, a warning display lamp 18 is displayed. By notifying (S0302), it is possible to notify the user of the abnormality of the device, and it is possible to realize a user-friendly garbage disposal machine with more stable performance.

  Now, in the low processing mode, FIG. 5 is a diagram showing the operating states of the stirring means 5 and the ventilation fan 10.

  As shown here, the operation of the ventilation fan 10 is stopped while the stirring means 5 is stirring or including the predetermined time tw after the stirring is stopped. An easy-to-use garbage disposal machine with little discharge of the substrate can be realized.

  In addition, although it demonstrated with the garbage processing machine of the type which decomposes | disassembles garbage with microorganisms through the Example of this invention, it is not limited to microorganisms in particular, and if it operates substantially continuously, drying will be carried out. Even if it is the main type and does not use microorganisms, it has the same effect.

  As described above, the garbage processing machine according to the present invention, for example, reduces the heat retention temperature of the treatment tank to about 5 ° C. when there is no input of garbage for a predetermined period, prevents unnecessary drying, and reduces the temperature. In this case, it is possible to provide a garbage processing machine that does not freeze and does not interfere with the input of garbage again and has more stable performance.
