Description

  The present invention relates to a bio-type garbage processing machine.

  This kind of garbage processing machine ferments and decomposes garbage with a processing material that supports aerobic microorganisms (bio-fungi) on a base material, and can be rotated in the processing tank of the processing machine body. A stirring means is disposed, and a heating means for heating the inside is disposed outside the processing tank. And while maintaining the inside of a processing tank in the predetermined temperature range by the said heating means, it processes by stirring the input garbage with a processing material by the said stirring means.

  Prior art document information related to the garbage processing machine of the present invention includes the following.

JP 2002-263620 A

  In Patent Document 1, the output shaft of the drive motor is projected from the bottom of the processing tank for the purpose of downsizing and improving the stirring efficiency, and the first is radially formed from a boss that can be attached to and detached from the output shaft. In addition, there is described a garbage processing machine in which a third arm is projected and a vertical stirring member provided with a blade portion on each arm is mounted.

  The first blade portion provided on the first arm is agitated so as to push up the treatment material near the bottom of the treatment tank, and is provided so as to be inclined downward in the rotation direction. The second blade portion provided on the second arm is agitated so as to push up the treatment material near the outer peripheral wall at the bottom of the treatment tank, and is provided so as to be inclined downward in the rotation direction. It is comprised so that it may be located in the radial direction outer side from the said 1st blade | wing part by the dimension of. The third blade portion provided on the third arm is agitated so as to push the processing material pushed up by the first and second blade portions into the center and the outer periphery of the processing tank. It has a pair of wing pieces.

  However, the vertical stirrer having the rotating shaft extending in the vertical direction in this way has the inclination angles (twist angles with respect to the horizontal direction) of the first and second blade portions that act to push the processing material upward. ) Setting is very difficult.

  Specifically, in order to improve the stirring efficiency of the treated material and garbage with this stirring member, the inclination angle of each blade portion is set to make an obtuse angle with respect to the horizontal direction, and effective for stirring action. It is preferable to increase the area. However, when the inclination angle is made obtuse in this way, the resistance to the blade portion due to the processing material and garbage increases, so the torque required for the drive motor for rotating the stirring member increases, and the cost increases. There is a problem of becoming high. As a result, the stirring member itself needs to have high strength, and the processing tank and the processing machine main body for fixing the drive motor also need to have high rigidity, which increases the cost of the entire apparatus. In addition, with the use of a drive motor having a large torque, there is a problem that the user feels bothered by noise during operation and power consumption increases.

  On the other hand, if the inclination angle of each blade portion of the stirring member is set so as to form an acute angle with respect to the horizontal direction, the above problem does not occur. However, there is a problem in that the stirring efficiency of the processing material and the garbage is lowered and the processing material is simply scraped off as the humidity of the processing material approaches a dry state. Specifically, in the first and second stirring blades, a sufficiently upward pressing force cannot be applied to the treatment material depending on the condition of the treatment material, and the treatment material flows outward as the rotation occurs. Act on. As a result, there is a case where the pressing force by the blade part escapes outward and is lost, thereby acting only to be scraped off. This problem is prominent when the treatment tank is deep and a large pressure is applied to the lower layer.

  The present invention has been made in view of conventional problems, and it is an object of the present invention to provide a garbage processing machine that can reliably agitate a processing material and garbage without increasing the torque of a driving means. It is.

In order to solve the above problems, a garbage processing machine of the present invention includes a processing machine main body having a processing tank for storing a processing material, a stirring member for stirring the garbage and the processing material stored in the processing tank, and In the garbage processing machine provided with a stirring means composed of a driving means, the stirring member acts so as to push the processing material upward by projecting radially outward from the rotating shaft extending in the vertical direction and the rotating shaft. And a vertical wall protruding in the vertical direction from the stirring blade.
Specifically, the stirring blade has a plurality of blade portions arranged radially at a predetermined interval in the vertical direction of the rotation shaft and at a predetermined interval in the circumferential direction.

  Since the garbage processing machine configured as described above is a vertical type in which the rotation shaft of the stirring member is arranged to extend in the vertical direction, it is possible to reduce the size in the horizontal direction and save space on the floor surface to be installed. Can be achieved. Further, in this stirring member, depending on the inclination angle of the stirring blade, as in the conventional case, a sufficiently upward pressing force cannot be applied to the processing material, so that the processing material flows outward according to the rotation. Works. However, in the stirring member, since the vertical wall protruding in the vertical direction is provided on the stirring blade that acts to push the processing material upward, the vertical wall can suppress the action of the processing material flowing outward. . As a result, since it becomes possible to sufficiently apply an upward pressing force to the treatment material by the stirring blade, a sufficient stirring action can be obtained even when the treatment tank is deep. In other words, the garbage processing machine of the present invention can increase the effective area for stirring without changing the inclination angle of the stirring blade by providing the stirring blade with a vertical wall extending in the vertical direction. The degree of freedom in designing the inclination angle can be improved. As a result, in order to improve the stirring efficiency, it is not necessary to apply a driving means having a large torque. Therefore, it is possible to reliably prevent the conventional problems associated with applying the driving means having a large torque.

  In the said garbage processing machine, it is preferable to provide an acute-angle blade part in the edge of the rotation direction front side of the said vertical wall. If it does in this way, the big lump of the processing material containing a water | moisture content and garbage with much fiber can be cut, and the decomposition processing efficiency by a processing material can be improved significantly.

  In addition, it is preferable that the edge on the front side in the rotation direction of the vertical wall is an inclined edge that is inclined from the upper side to the lower side in the rotation direction. In this way, since it acts so that garbage may be taken in on a stirring blade, the stirring efficiency of a processing material and garbage can further be improved.

Furthermore, it is preferable to provide a plurality of the vertical walls at a predetermined interval radially outward about the rotation axis.
In this case, it is preferable to lower the overall height of the second vertical wall located outside than the first vertical wall located near the rotation axis.
In this way, the load on the stirring blade can be made uniform inside and outside in the radial direction.

  In the garbage processing machine of the present invention, since the vertical wall protruding in the vertical direction is provided on the stirring blade that acts to push up the treatment material upward, the treatment material flows outwardly by the vertical wall. Can be suppressed. As a result, it is possible to sufficiently apply an upward pressing force to the treatment material by the stirring blade, and a sufficient stirring action can be obtained even when the treatment tank is deep. Therefore, the degree of freedom in designing the inclination angle of the stirring blade itself can be improved, and it is not necessary to apply a large torque drive means to improve the stirring efficiency. Therefore, it is possible to reliably prevent the conventional problems associated with applying the driving means having a large torque.

  As shown in FIG. 6, the garbage processing machine configured as described above has a detection function for detecting the state of the processing function of decomposing the garbage with the processing material accommodated in the processing tank 20. Three temperature sensors 60 to 62 for detecting the temperature in the processing tank 20, the temperature of the processing material, and the temperature of the outside air are disposed. The processing tank temperature sensor 60 is disposed above the processing material in the processing tank 20. The substrate temperature sensor 61 is disposed on the bottom in the processing tank 20. The outside air temperature sensor 62 is disposed on the exterior body 11 of the processor main body 10.

  And as shown in FIG. 1, the control board 63 is arrange | positioned in the front lower part between the said exterior body 11 and the processing tank 20, The microcomputer 64 which is a control means mounted in this control board 63 is as follows. It operates according to a preset program. Specifically, the microcomputer 64 operates by converting electric power from a commercial power source into a DC voltage by the power supply circuit unit 65 and applying the DC voltage. Then, it functions as a lid opening means, and when the distance measuring sensor 46 detects that an object including a human body has come within a detectable range, the locking means 59 is operated to engage the locking receiving portion 58. By releasing the stop, the lid 54 is automatically opened by the biasing force of the hinge spring 55. When detecting that the lid body 54 is closed by the switch 57, the time measurement is started by the built-in time counting timer 66 using the closed time as a starting point of control, and the heater 45 is turned on and off. Then, control of the rotation of the stirring member 28 is started. Further, it functions as a processing material state determination means for determining the state of the processing function of the processing material based on the detection values of the temperature sensors 60 to 62 every predetermined time, and the heater 45 is turned on / off based on the determination result. In addition, the rotational speed of the stirring member 28 is controlled, and the state of the processing function of the processing material is displayed on the display unit of the operation panel 67.

  The garbage processing machine of the present embodiment configured as described above is a vertical type in which the rotation shaft 30 of the stirring member 28 is arranged so as to extend in the vertical direction, and thus can be miniaturized in the horizontal direction. Space can be saved on the floor. Moreover, since the drive motor 29 of the stirring member 28 is disposed on the partitioning partition plate 17 which is the upper part of the processing tank 20, there is no possibility of short-circuiting due to adhesion of water contained in raw garbage. It is possible to suppress the occurrence of malfunctions and failures.

  Furthermore, since the rotating shaft 30 of the stirring member 28 is supported at the upper end by the drive motor 29 and supported at the lower end by a cylindrical bearing portion 24 provided at the bottom of the processing tank 20, the mounting structure is special. Simplification can be achieved without the need for parts. And although the said bearing part 24 is provided in the bottom of the processing tank 20, since no hole is provided, the water in the processing tank 20 leaks outside (between the exterior body 11 and the processing tank 20). Can be prevented. As a result, it is possible to prevent the leaked water from adhering to the control board 63 disposed at the lower part of the processor main body 10, and to prevent malfunctions and failures due to the water leak.

  Furthermore, the stirring blade of the stirring member 28 has a plurality of blade portions 35, 40A, 40B arranged radially, and the first blade portion 35 at the lower end thereof is formed by a cover portion formed by the first rib portion 37b. Since the upper end of the bearing portion 24 is covered, it is possible to prevent the pulverized material and processing material from being disposed between the bearing portion 24 and the rotary shaft 30 from entering. As a result, it is possible to prevent the generation of noise due to the entry of foreign matter between the rotating shaft 30 and the bearing portion 24. Further, when the invading foreign matter is a powdered egg shell that acts as an abrasive, the lower end of the rotating shaft 30 or the bearing portion 24 is worn, and the gap between them is widened, whereby the stirring member 28 When the is rotated, there is a problem that the entire device vibrates. However, in the present embodiment, it is possible to reliably prevent such a problem from occurring, and it is possible to prevent life deterioration.

  In addition, the base member 25 and the rotary shaft 30 constituting the bottom of the bearing portion 24 are provided with spherical concave portions 26 and 31 that are recessed in a substantially hemispherical shape, and a spherical member 27 is provided therebetween, and the rotary shaft 30 and Since the resistance with the bearing portion 24 can be suppressed, the rotating shaft 30 can be supported so as to be smoothly rotatable. Further, the rotary shaft 30 of the stirring member 28 and the output shaft 29a of the drive motor 29 are connected by a joint member 33, and the rotary shaft 30 and the output shaft 29a are non-circular convex portions 29b having a D-shaped cross section, 32 and a non-circular recess 34 is provided in the joint member 33. That is, since the stirring member 28 of this embodiment is the structure which supports the both ends of the rotating shaft 30, the rigidity in an assembly state can be improved. And since the connection part of the both ends is performed by insertion / extraction, the assembly workability | operativity and removal workability | operativity can be improved.

  Next, the stirring action when the stirring member 28 is rotated will be specifically described. The operation of the stirring member 28 is determined by the microcomputer 64 based on the temperature detected by the temperature sensors 60 to 62, and the state (water content) of the treatment material is determined. The time to be changed is changed.

  When the agitating member 28 is rotated by the drive motor 29, each blade portion 35, 40A, 40B has a processing material containing garbage due to the effective stirring surface by being inclined downward toward the front side in the rotation direction. Pushed up. Here, the upward pressing force by the blade portions 35, 40A, and 40B may act so that the treatment material flows outward in accordance with the rotation, escapes outward, and is lost as in the conventional case. However, in this embodiment, it can suppress that a processing material flows outward by the vertical walls 38A-38C and 43A-43C which were provided in each blade | wing part 35, 40A, 40B. As a result, the upward pressing force can be sufficiently applied to the processing material by the blade portions 35, 40A, 40B.

  As described above, in the stirring member 28 of the present invention, since the upward pressing force can be reliably applied to the processing material regardless of the inclination angle of each of the blade portions 35, 40A, 40B, the processing tank 20 is deep. Even so, a sufficient stirring action can be obtained. In other words, the garbage processing machine according to the present invention is provided with the vertical walls 38A to 38C and 43A to 43C on the blade portions 35, 40A, and 40B, so that the inclination angles of the blade portions 35, 40A, and 40B are acute angles (slowly). ), The effective area for stirring can be increased without changing the inclination angle. Therefore, the freedom degree of design of the inclination angle of the blade | wing part which comprises a stirring blade can be improved. Further, in order to improve the stirring efficiency, it is not necessary to apply the drive motor 29 having a large torque as the drive means. Therefore, the conventional problems associated with applying the drive motor 29 having a large torque can be reliably prevented.

  Further, in the present embodiment, the sharp edges 39 and 44 are provided at the front edge in the rotational direction of the vertical walls 38A to 38C and 43A to 43C, so that a large lump of moisture-containing treatment material or fibers High quality garbage can be cut. As a result, the decomposition efficiency by the processing material can be greatly improved.

  Here, in the case where a plurality of vertical walls 38A to 38C and 43A to 43C are provided on each of the blade portions 35, 40A, and 40B as in the present embodiment, the vertical wall 38C that is provided at a location away from the rotary shaft 30. , 43C has a larger load applied during the rotation than the vertical walls 38A, 43A close to the rotating shaft 30. In addition, it has been confirmed by experiments that the garbage thrown into the treatment tank 20 tends to gather around the rotating shaft 30 when the stirring member 28 is rotated.

  And in this embodiment, since each vertical wall 38A-38C and 43A-43C are formed so that the total height may become low in order toward radial direction outer side, each vertical wall 38A-38C, 43A-43C. Can be made uniform. Moreover, since the garbage collected in the vicinity of the rotating shaft 30 can be reliably cut by the vertical walls 38A and 43A having a high overall height, the efficiency of the decomposition process of the garbage can be reliably improved.

  In addition, the garbage processing machine of this invention is not limited to the structure of the said embodiment, A various change is possible.

  For example, as shown in FIGS. 7A, 7 </ b> B, and 7 </ b> C, the vertical walls 38 </ b> A to 38 </ b> C and 43 </ b> A to 43 </ b> C of the blade portions 35, 40 </ b> A, and 40 </ b> B It is good also as the structure which set it as the inclined edges 38a and 43a which incline below in the rotation direction toward the downward direction, and provided the said blade parts 39 and 44 in the inclined edges 38a and 43a. In this way, when the agitating member 28 is rotated, it acts to take in the lump of the processing material and garbage into the upper surfaces of the blade portions 35, 40A, 40B, thereby further improving the agitation efficiency of the processing material and garbage. it can.
