Description

  The present invention relates to a microwave heating type garbage processing machine, and more particularly, to a garbage processing machine that puts garbage in a processing container, stirs it, and heats and dries by irradiating microwaves while chopping with a rotating cutter. .

As this kind of garbage processing machine, there is one described in Japanese Patent Laid-Open No. 11-333415 previously proposed by the present inventors. In this garbage disposal machine, a microwave irradiation port is provided at the lower part of the side wall of the processing container and is closed with a microwave transmitting material, and the microwave from the microwave oscillator is irradiated into the processing container from the microwave irradiation port. A rotating cutter and a stirring blade are separately supported on the same axis line at the bottom in the processing vessel, and the rotating cutter is rotated slightly above the stirring blade at a higher speed to shred the garbage at the same time as stirring. It is like that.
JP-A-11-333415

  The present inventor made a prototype of a garbage processing machine having such a structure and conducted various experimental researches. If the raw garbage is dried to some extent, it will be heated locally by microwave irradiation, causing ignition, scorching, or shredding with a rotating cutter. We faced various problems such as the raw garbage and the water released at once from the raw garbage became bowl-like at the bottom of the processing container and shredded with a rotating cutter, which increased the processing time. In order to solve this problem, structural improvements have been made repeatedly, but it has been difficult to find the clue.

  As a result of trial and error, the present inventor found that when the raw garbage at a stage where drying is still insufficient and still contains a lot of moisture, the rotating cutter is suddenly rotated at a high speed and shredded, the raw garbage becomes bowl-shaped. When the food waste falls into the result of giving viscosity to the garbage, or while moisture still remains in the garbage, the microwave is absorbed by the moisture, but the garbage loses moisture. As the humidity of the processing vessel decreases, the absorption of microwaves due to moisture gradually decreases, so if you cut and agitate the garbage under the same conditions, you may experience excessive local heating due to microwave irradiation. I found out that I was invited.

  And from such knowledge, it came to devise the present invention which can easily eliminate the above-mentioned problems that could not be solved by structural improvements.

  The first aspect of the present invention is to detect the exhaust temperature to the outside of a processing container in a garbage processing machine that puts garbage into a processing container and irradiates it with microwaves while chopping it with a rotating cutter to heat and dry it. Input the temperature sensor, the input operation unit that can be input for each processing name indicating the type of garbage, and the rotation pattern of the cutter motor that rotates the rotating cutter for each processing name that indicates the type of garbage. Cutter motor control means for controlling the cutter motor so as to obtain a rotation pattern for each set process name by arbitrarily setting on the operation unit, and a plurality of processes indicating the type of garbage in the stop temperature at the end of drying A drying process automatic stop means is provided to automatically stop the drying process when the detected temperature of the temperature sensor reaches the set temperature for each process name by arbitrarily setting the input operation unit for each name. Special To.

  According to a second aspect of the present invention, in a garbage processing machine that puts garbage into a processing container and irradiates it with microwaves while chopping it with a rotating cutter and heats it to dry, it detects the exhaust humidity outside the processing container. Input the humidity sensor, input operation unit that can be input for each processing name indicating the type of garbage, and rotation pattern of the cutter motor that rotates the rotating cutter for each processing name that indicates the type of garbage. Cutter motor control means for controlling the cutter motor so as to obtain a rotation pattern for each set process name by arbitrarily setting on the operation unit, and a plurality of processes indicating the type of garbage for the stop humidity at the end of drying A drying process automatic stop means is provided that automatically stops the drying process when the detected humidity of the humidity sensor reaches the set humidity for each process name by arbitrarily setting the input operation unit for each name. Special To.

  According to the present invention, since the rotation pattern of the cutter motor can be arbitrarily set for each of a plurality of processing names indicating the type of garbage, for example, at the stage where the garbage contains a lot of moisture, the rotational speed of the rotating cutter is set. If it is kept low and the raw garbage is cut into large pieces and the rotational speed of the rotating cutter is increased stepwise or continuously as the moisture content decreases and drying proceeds, it is shredded in a state that contains a lot of moisture. As the drying progresses, the garbage is cut into fine pieces, and by changing the shredding speed and the stirring speed of the fine fragments, the progress of water evaporation for each kind of garbage Heating by microwave irradiation is consistently and appropriately performed in accordance with shredding, enabling efficient and uniform heating under temporally averaged temperature conditions, and local overheating by microwave irradiation. It can be stopped.

  At the beginning of operation, water is rapidly released from the garbage by heating with stirring, and when the garbage is heated by microwaves, the temperature rises suddenly to a certain height, but then does not rise so much. It is easier to cut after waiting for the heating. In addition, when cut from the beginning, the garbage becomes bowl-shaped as described above, or becomes viscous and becomes a nodule, but if the cutter motor is not rotated within a certain period of time from the start of microwave irradiation, This can be avoided.

  In addition, although there are a wide variety of garbage, the input operation unit can be used to easily perform appropriate processing according to the type of contents, input amount, moisture amount, etc. (hereinafter collectively referred to as the kind of garbage). The type of garbage can be selected in accordance with the input from now on, and the rotation pattern of the cutter motor can be set for the selected type of garbage by input from the input operation unit.

  Furthermore, if the drying end point for each type of garbage is arbitrarily set by temperature or humidity by touch input according to the menu displayed on the input operation unit, detection of the temperature sensor that detects the exhaust temperature outside the processing container When the humidity detected by the humidity sensor that detects temperature or exhaust humidity reaches the set temperature or set humidity, the drying process automatically stops, so appropriate drying process according to the type of garbage while preventing ignition Can be done.

  Next, embodiments of the present invention will be described in detail with reference to the drawings.

  1 to 3 are overall mechanism diagrams of Embodiment 1 of the present invention. Example 1 is a method in which a processing vessel is fixed and a stirring blade is rotated therein, and the basic configuration is the same as that described in the above-mentioned Japanese Patent Application Laid-Open No. 11-333415, and a bottomed cylindrical shape is used. The metal processing container 1 is fixedly installed in the housing 2, and the upper surface opening of the processing container 1 can be opened and closed by a microwave shielding upper lid 3 hinged to the housing 2. Two microwave irradiation ports 4 closed by a microwave transmitting material are provided, and two waveguides 5a and 5m are respectively provided from two magnetrons (microwave oscillators) 5 installed between the processing vessel 1 and the housing 2. A microwave is irradiated into the processing container 1 through the microwave irradiation port 4.

  Further, the air duct 6 and the exhaust duct 7 are connected to the processing vessel 1, and the air heated by the cooling fan in each magnetron 5 is heated by the heater 18 in the subsequent stage of each magnetron 5. The gas in the processing container 1 is blown from the exhaust port (not shown) provided in the upper part of the processing container 1 by the exhaust fan 8 while being blown as warm air into the processing container 1 through the air duct 6. Forced exhaust is performed through the exhaust duct 7 to the outside. A temperature sensor 19 is disposed at the inlet of the exhaust duct 7, and the temperature in the processing container 1 is detected by the temperature sensor 19. Furthermore, as shown in FIG. 4, a plurality of drain holes 1 a sized so as not to leak microwaves are provided at the bottom of the processing container 1, so that water can be automatically drained therefrom.

  On the other hand, a cutter shaft 9 and a cylindrical stirring shaft 10 are concentrically passed through the center of the bottom of the processing vessel 1, and a rotating cutter 11 is fixed to the upper end of the cutter shaft 9 as shown in FIG. The stirring blade 12 is fixed to the stirring shaft 10 below the rotary cutter 11. As shown in FIG. 1, the rotary cutter 11 is rotated in one direction by a cutter motor 13 installed in the lower part of the housing 2, and the stirring blade 12 is bidirectionally driven by a stirring motor 14 installed in the lower part of the housing 2. Can be reversed.

The configuration so far is almost the same as the conventional one, but the configuration described below is different from the conventional one.
First, the structure of the rotary cutter 11 will be described. As shown in FIGS. 4 and 5, the rotary cutter 11 is configured by combining long cutter blades 15 and short cutter blades 16 so as to cross each other. FIG. 8 shows only the long cutter blade 15 and FIG. 9 shows only the short cutter blade 16. The long cutter blade 15 extends horizontally with a slight gap between the blade 15a and the upper surface of the stirring blade 12 after both blades 15a fall vertically along the outer periphery of the core 12a of the stirring blade 12. The tip is inclined upward.

  The short cutter blade 16 has one of its blades 16a extending horizontally and the other extending obliquely upward from the middle. Further, the shape seen from above is such that both the long cutter blade 15 and the short cutter blade 16 go to the tip while curving in a C-shape toward the rotation direction of the rotary cutter 11 so that both of the blades can be easily cut. Pointed according to.

  Next, as shown in FIG. 4 to FIG. 6, the stirring blade 12 is formed by projecting horizontally from a cap-shaped core 12 a with both blades 12 b symmetrical, and the lower surface of both blades 12 b is flat with the processing vessel 1. Although it is flat so as not to form a gap with the bottom surface, when viewed from the top surface of both wings 12b, it has a mountain shape, and one side 12d of the highest peak portion 12c is gradually inclined and gradually decreases. At the same time, the edge becomes wider toward the tip while drawing a gentle curve, and the opposite side 12e of the peak 12c is a steep slope that rounds the peak 12c, and the edges of both wings 12b are parallel to each other. It has become. Furthermore, the tip surface 12f and the corners of both blades 12b are also rounded.

  A scraper 17, which is a round bar, is erected vertically at the tip of the peak portion 12 c of both blades 12 b of the stirring blade 12, and each scraper 17 has a vertically long protruding portion 17 a that is in sliding contact with the inner peripheral surface of the peripheral wall of the processing container 1. Is provided.

  As shown in FIG. 4, a discharge port 1b is provided in the vicinity of the drain hole 1a in the lower portion of the peripheral wall of the processing container 1, and this discharge port 1b is mounted on the outer peripheral wall of the processing container 1 as shown in FIG. It is opened and closed by the discharge door 100. 10 to 15 show specific examples of the mounting structure.

  The discharge door 20 is hinged to the outside of the peripheral wall of the processing container 1 by a hinge 21 so that it can be opened and closed. A hook 23 of a lock lever 22 pivotally supported on the outer side of the free end of the discharge door 20 is attached to the outer side of the peripheral wall of the processing container 1. By engaging with the chuck 24, the closed state can be locked. In this state, the convex portion 20a on the curved inner surface of the discharge door 20 fits into the discharge port 1b and is flush with the inner peripheral surface of the peripheral wall of the processing container 1, as shown in FIG.

  On the outer surface of the discharge door 20, an opening angle switching operation piece 25 is hinged so as to be opened and closed by a hinge 26 and closed by a torsion coil spring. The opening angle switching operation piece 25 has a knob portion 25a integrally projecting therefrom. On the other hand, a stopper projecting piece 27 is fixed to the fixed side (processing container 1 side) base portion 21a of the hinge 21 of the discharge door 20.

  As shown in FIGS. 10 and 13, when the discharge door 20 is closed, the free end 25 b of the opening angle switching operation piece 25 is separated from the stopper projecting piece 27 and is in pressure contact with the fixed side base portion 21 a.

  Accordingly, when the lock lever 22 is turned to release the lock and then the lock lever 22 is pulled forward and the discharge door 20 is opened, as shown in FIG. 11 and FIG. When the end 25b comes into contact with the stopper protrusion 27, the opening of the discharge door 20 is restricted, and the discharge door 20 is in a half-open state.

  While holding the knob 25 a of the opening angle switching operation piece 25, the lock lever 22 remains open until the free end 25 b of the opening angle switching operation piece 25 exceeds the stopper protrusion 27. Is pulled forward, the discharge door 20 is further opened from the half-opened state, and as shown in FIGS. 12 and 15, the open door 25 b is fully opened until the free end 25 b of the opening angle switching operation piece 25 comes into contact with the outer peripheral surface of the processing container 1. Opened.

  The opening / closing of the discharge door 20 is detected by the discharge door opening / closing detection sensor 28 shown in the block diagram of FIG. 16, and the opening / closing of the microwave shielding upper lid 3 on the upper surface of the processing container 1 is also detected by the upper lid opening / closing detection sensor 29. The

  The magnetron 5, the exhaust fan 8, the cutter motor 13, the agitation motor 14, the heater 18, and the like are controlled by a control panel according to an operation on a touch operation panel 30 (see FIG. 2) that is an input operation unit installed at the upper front of the housing 2. Is controlled by a control circuit 31 including a CPU, a ROM, and the like provided in. FIG. 16 shows a block diagram of an electrical configuration.

  In FIG. 16, the screen display of the touch operation panel 30 changes as described later according to a program written in the ROM in the control circuit 31, and an input to the control circuit 31 is performed by touching the screen. In addition to the detection signals from the temperature sensor 19, the discharge door opening / closing detection sensor 28, and the upper lid opening / closing detection sensor 29, the control circuit 31 includes a power switch 32 and an emergency stop switch 33 disposed in the vicinity of the touch operation panel 30. A signal is also input, and the driver circuits 5 a, 8 a, 13 a, 14 a, and 18 a of the magnetron 5, the exhaust fan 8, the cutter motor 13, the stirring motor 14, and the heater 18 are controlled by the control circuit 31. The alarm device 34 is also controlled. It should be noted that a humidity sensor 19a may be used instead of the temperature sensor 19, and control as described later may be performed from both the temperature and humidity using both the temperature sensor 19 and the humidity sensor 19a.

  FIG. 17 shows a timing chart of operations of the agitation motor 14 and the cutter motor 13 controlled by the control circuit 31 in contrast to changes in temperature and humidity in the processing container 1.

  The agitation motor 14 is controlled by the control circuit 31 from the start of the operation of the garbage processing machine (at the start of microwave irradiation) to the normal rotation at a certain time t1, the stop at the certain time t2, and the reverse rotation at the certain time t3. The phase operation is repeated periodically. These times t1, t2, and t3 are arbitrarily set on the touch operation panel 30.

  Under the control of the control circuit 31, the cutter motor 13 is kept rotating for the required time T0 set on the touch operation panel 30 from the start of operation of the garbage disposal machine (at the start of microwave irradiation), and thereafter intermittently. And the number of rotations is increased stepwise. The step switching time (time until switching to the next step) T1 to Tn, the intermittent time t of the intermittent rotation at each step, and the rotation speed r are described later on the touch operation panel 30. Is set arbitrarily.

  The garbage thrown into the processing container 1 is irradiated with microwaves at the lower part of the processing container 1 from the start of operation while being stirred by repeating the three stages of forward, stop and reverse rotation of the stirring blade 12. Heated. The garbage is agitated so that it is lifted up to the peak 12c by one side 12d of the gently sloping blades 12b by the forward rotation of the agitating blades 12b and close to the center. By the reversal of the blades 12, the agitation is performed so that the blades 12 bounce up to the tops 12 c on the opposite sides 12 e of the both blades 12 b. By such various stirring by the stirring blades 12, microwave penetration into the garbage is uniformly performed properly.

  Since the tip surfaces 12f of both blades 12b of the stirring blade 12 are rounded, a solid material such as a fish bone is sandwiched between the tip surface 12f and the inner peripheral surface of the processing vessel 1, and the stirring blade 12 Rotation is not impeded. Further, the scraper 17 scrapes the garbage attached to the surface of the microwave transmitting material of the microwave irradiation port 4 and the inner peripheral surface of the processing container 1 at the same time as stirring, so that it does not move and remains scorched without moving. There is no.

  The rotation cutter 11 is kept rotating for the required time T0 from the start of operation, and then intermittently rotated, and the rotation speed is increased stepwise as time elapses. This is because, at the beginning of operation, water removal from the garbage is rapidly performed by heating while stirring, and in the case of heating the garbage by microwave, the temperature in the processing container 1 is rapidly increased to a certain height. However, since it does not increase so much after that, it is more likely that the water generated by the cutting will start when the cutting by the rotary cutter 11 is started after waiting for sufficient water removal from the garbage and heating by the microwave. This is because the absorption rate of microwave energy is small, the utilization efficiency of microwave energy is increased, and cutting is facilitated. In addition, when the garbage is suddenly cut (chopped) from the beginning of operation, it becomes a bowl shape or a nodule due to viscosity, but when the size of the scrap of garbage is initially large and gradually becomes finer, This can be prevented and the load on the rotary cutter 11 can be reduced.

  Furthermore, as the garbage is dried and shredded, the moisture contained in the fine fragments decreases, the absorption of microwaves by the moisture decreases, and the amount of heat accumulated in each fine fragment also increases. It is because it will ignite or burn if it does not raise the stirring speed while cutting the further fragmentation by 11 and its fine piece. When the rotation of the rotary cutter 11 is controlled in this way, the temperature in the processing container 1 can be stabilized, the vaporization of moisture from each fine piece and the heat dispersion can be promoted, and excessive heating is performed. It is possible to heat efficiently while suppressing the above.

  Since the rotary cutter 11 has the structure as described above by the long and short cutter blades 15 and 16, the garbage that is pushed up by the both blades 12b of the stirring blade 12 can be cut by both blades of the long cutter blade 15 and the long cutter blades. At the falling edge of 15, the garbage on the outer peripheral portion of the core 12 a of the stirring blade 12 can be cut, and the garbage on the upper surface portion of the core 12 a of the stirring blade 12 can be removed at one horizontal blade portion of the short cutter blade 16. It can cut | disconnect and the garbage above the core 12a of the stirring blade 12 can be cut | disconnected by the other inclined blade part. And it can also stir simultaneously with such extensive cutting.

  As described above, the stirring blade 12 repeats the three-stage operations of normal rotation, stop, and reverse rotation, and the rotary cutter 11 rotates intermittently and increases the rotation speed stepwise as time passes. Since it rotates in the direction (forward rotation direction of the stirring blade 12), the stirring and cutting of the garbage is performed in an extremely complicated manner, and the shredding of the garbage, heating, and heat dispersion are performed efficiently. Note that the rotational speed of the rotary cutter 11 may be increased continuously instead of stepwise. It is also possible to easily set the speed at the time of forward rotation and reverse rotation of the stirring blade 12 as desired.

  Next, touch input by the touch operation panel 30 and control and operation performed based on the touch input will be described according to the screen display.

  FIG. 18 is a screen display of the touch operation panel 30 after the power is turned on with the power switch 32 turned on.

  Next, Example 2 which is a method of rotating and stirring the processing container itself will be described. 28 to 30 show the whole, and FIG. 31 shows a part thereof in an enlarged manner. In the second embodiment, a processing container 51 made of a microwave transmitting material (plastic) is used, and this is detachably mounted on a rotation cradle 54 in a microwave shielding chamber 53 provided in a housing 52. The rotary cradle 54 is rotated together.

  The microwave shielding chamber 53 is surrounded on a surface other than the upper surface by a metal plate 55 such as stainless steel that reflects microwaves, and the upper surface opening can be opened and closed by a microwave shielding upper lid 56 hinged to the housing 52. The microwave shielding upper cover 56 is opened so that the processing container 51 can be taken out from the upper surface opening of the microwave shielding chamber 53.

  In the microwave shielding chamber 53, the microwave from the microwave generator 57 installed in the housing 52 is irradiated from the lower side wall of the microwave shielding chamber 53 through the waveguide 58. In addition, the wind provided to cool the microwave generator 57 by the cooling fan 59 can be blown from the upper part of the side wall of the microwave shielding chamber 53 through the blower duct 60. On the other hand, an exhaust port 61 communicating with the outside of the housing 52 is provided on the side wall of the microwave shielding chamber 53 on the opposite side of the air duct 60a at the tip of the air duct 60 so that it can be forcibly exhausted by an exhaust fan (not shown). It has become.

  The processing vessel 51 has a bottomed cylindrical shape that tapers near the bottom, and its upper surface opening is closed with a top lid 62 that is hinged or detachable. The upper lid 62 has a concave portion 62a at the center, and a handle 63 for taking in and out the processing container 1 is provided inside the concave portion 62a (outside the center of the upper lid 62). A handle 51a is also provided on the peripheral wall of the processing container 51 itself. Further, the outer peripheral wall 62 b of the upper lid 62 has a mesh structure in order to introduce the air from the air outlet 60 a of the air duct 60 into the processing container 51 and exhaust it through the air outlet 61. That is, the outer peripheral wall 62b itself serves as an intake portion and an exhaust portion. An annular space 64 is formed between the outer peripheral wall 62b and the peripheral wall of the recess 62a. The air that has entered the annular space 64 from the air blowing port 60a is directed downward in the processing vessel 51 and exhausted. At this time, the peripheral wall 62c of the concave portion 62a is bent and hung so as to go to the exhaust port 61. Note that air may be blown into the processing container 51 not from the annular space 64 but from directly above (a portion corresponding to the recess 62a).

  As shown in an enlarged view in FIG. 31, a cutter shaft 66 having a cap-shaped cutter rotating core 65 is rotatably supported by a bearing 67 and is rotated on the cutter rotating core 65. The cutter 68 is tightened. Both blades of the rotating cutter 68 fall on the outer periphery of the cutter rotating core 65 as viewed from the cutter shaft 66 and then extend horizontally along the flat bottom surface of the processing vessel 51, and the tips of both blades are tapered. It is inclined upward along the side surface.

  At the lower end of the cutter shaft 66, a joint portion 66 a is provided outside the bottom of the processing container 51. When the processing container 51 is mounted on the rotation cradle 54, this joint portion 66 a is installed in the housing 52. The cutter motor 69 (FIG. 28) is coupled to a joint portion 70a on the cutter motor shaft 70 side so that the rotation of the cutter motor 69 can be transmitted to the rotary cutter 68.

  On the other hand, the rotation pedestal 54 is a bottomed cylindrical shape having a size that can be fitted to the cylindrical seat 51b at the bottom of the processing vessel 51, and has a cylindrical shaft 71 through which the cutter motor shaft 70 penetrates. A cylindrical shaft 71 is rotatably supported by a bearing 72 at the bottom center of the microwave shielding chamber 53. The cylindrical shaft 71 transmits the rotation of the stirring motor 73 (FIG. 28) installed in the housing 52 via a pulley and a belt.

  The cutter motor 69 is controlled by a cutter motor control circuit, and the stirring motor 73 is controlled by a stirring motor control circuit as shown in the timing chart of FIG. That is, the rotation cradle 54 and the processing vessel 51 mounted on the rotation cradle 54 are operated in three stages: forward rotation at a predetermined time t1, stop at a predetermined time t2, and reverse rotation at a predetermined time t3, like the stirring blade 12 of the above-described embodiment. Is repeated periodically. Further, the rotation cutter 68 is held by the cutter motor control circuit for a required time T0 arbitrarily set from the start of the operation of the garbage disposal machine (at the start of microwave irradiation), and is rotated intermittently thereafter. In addition, the rotational speed is increased stepwise. The switching time (time until switching to the next step) T1 to Tn, the intermittent time t of the intermittent rotation in each step, and the rotation speed r are arbitrarily set.

  In this embodiment, the garbage is largely stirred by rotating the processing container 51 itself. However, since the upper lid 62 of the processing container 51 rotates integrally with the processing container 51, the outer peripheral wall 62b of the upper lid 62 is meshed. By doing so, air can be blown and exhausted into the processing container 51.

  A plurality of drain holes 74 sized so as not to leak microwaves are provided at the bottom of the processing container 51, and the drain generated in the processing container 51 falls into the drain collection container 75 through the drain holes 74. The drain collection container 75 is detachably inserted into the rotation receiving base 54 and can be taken out simultaneously with or separately from the processing container 51.

  Since the cylindrical seat portion 51 b of the bottom of the processing container 51 is fitted to the rotation receiving base 54, the bottom of the processing container 51 also has a function as an upper cover for the rotation receiving base 54 and the drain collection container 75.

  The drain collection container 75 may be detachably installed in the housing 52 outside the microwave shielding chamber 53, and the drain from the drain hole 74 at the bottom of the processing container 51 may be guided to the drain collection container 75. Further, the upper lid 62 of the processing container 51 can be structured not to rotate integrally with the processing container 51. In that case, the processing container 51 can be taken in and out of the microwave shielding chamber 53 by holding the handle of the upper lid 62, and when the processing container 51 is mounted on the rotation cradle 54, the upper lid 62 is in relation to the microwave shielding chamber 53. The air inlet provided in the upper lid 62 is fixed and coincides with the air outlet 60a of the air duct 60, and the air outlet provided in the upper lid 62 coincides with the air outlet 61 communicating outside the housing 52 and remains in this state. Even if the processing container 51 rotates together with the rotation cradle 54, the upper lid 62 does not rotate, and the fitting portion of the upper lid 62 is in sliding contact with the upper surface opening of the processing container 51 to prevent the processing container 51 from swinging. A structure that can be used is good.
