Description

  The present invention relates to a garbage processing machine that processes and reduces the amount of garbage generated in a kitchen or the like.

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

Japanese Patent No. 3298511 JP-A-10-99841

  Patent Document 1 discloses a drying-type garbage that supplies warm air to an upper part of a container in which raw garbage is stored and performs a drying process while pulverizing the garbage with a fixed blade and a rotary blade provided in the storage container. A processing machine is described. In this garbage disposal machine, the storage container is configured to be detachably disposed along with the rotary blade with respect to the exterior body, and is configured so that the garbage after drying can be taken out and discarded.

  However, the garbage processing machine has a problem in that it is inconvenient to use because it is necessary to take out the storage container and discard the dried garbage after processing each time the garbage is processed. In addition, even if the previously processed dry waste remains in the storage container, if there is a space for storing new raw waste, it is possible to continue processing, but in this case , The time required for processing becomes longer.

  In addition, when discarding dry garbage from the storage container, there is a stirring member with a blade for breaking the garbage inside. There is a risk of injury. In addition, by making it possible to remove the stirring member from the storage container, the problem of workability related to disposal can be solved, but in this case, it is necessary to take out the stirring member present in the discarded garbage. Because of this, the possibility of injury cannot be eliminated.

  Furthermore, since the stirring member of the said garbage processing machine makes the cantilever structure which supported only the lower end rotatably, it is weak in rigidity. As a result, since hard garbage cannot be crushed, there exists a problem that processing efficiency is bad.

  Patent Document 2 describes a garbage processing machine having a stirring member in which a rotating shaft is penetrated in a horizontal direction inside a processing tank and a blade is provided on the rotating shaft. And in this garbage processing machine, by providing a discharge port that can be opened and closed in the treatment tank so as to be located on the outer periphery of the rotation locus of the stirring member, by rotating the stirring member in a state where the discharge port is opened, It is configured so that treated garbage can be discharged out of the treatment tank.

  Since the garbage processor of this patent document 2 is supported at both ends so that the rotating shaft of the stirring member penetrates the treatment tank, it is possible to ensure the rigidity related to the crushing of the garbage. However, since a rotation shaft is installed at the center of the treatment tank, the storage volume and the stirring region in the storage container are reduced by the space occupied by the rotation shaft. In addition, since the wing portion that is also used for stirring and discharging the garbage has a structure in which the pipe member is bent in a substantially L shape, there is a problem that the efficiency with respect to the discharge is poor.

  The present invention has been made in view of conventional problems, and an object of the present invention is to provide a garbage disposal machine capable of improving the convenience of use and improving the processing efficiency.

  In order to solve the above-described problems, the present invention firstly provides a processing machine main body having a processing tank for storing raw garbage, and a lid that is disposed in the processing machine main body so as to be openable and closes an inlet to the processing tank. In a garbage processing machine comprising a body, a stirring member for stirring the garbage in the treatment tank, and a heating means for heating the garbage in the treatment tank, the stirring member can be rotated forward and reverse A pair of bearing plate portions fixed to a pair of shaft portions disposed at opposite positions of the processing tank and extending in a direction substantially orthogonal to the shaft center of the shaft portions; A blade portion extending between the tips of the bearing plate portions, a discharge port that can be opened and closed is provided on a surface located on the outer peripheral portion of the rotation locus of the stirring member in the processing tank, and the discharge port is provided outside the processing tank. Disposing a waste container to store the discharged garbage and driving the By rotating the stirring member in the forward rotation direction by the step, the trash in the processing tank is stirred by the wing part, and by rotating in the reverse direction, the trash in the processing tank is discharged from the discharge port by the wing part. It is an object of the present invention to provide a garbage disposal machine characterized by being made possible.

  According to this garbage processing machine, since it can be set as the structure which does not have a shaft in the center of a processing tank, after ensuring rigidity, the reduction | decrease of the storage volume and stirring area | region of garbage can be prevented. In addition, it is possible to prevent inconvenience that garbage is caught in the shaft during stirring. As a result, it is possible to improve the processing efficiency of garbage.

  Further, the garbage can be stirred and crushed by rotating in the forward direction, and the garbage can be discharged from the discharge port to the waste container by rotating in the reverse direction. Therefore, both the stirring function and the discharge function can be provided by one stirring member. As a result, it can be realized at low cost without complicating the internal structure.

In this garbage processing machine, it is preferable that the wing portion of the stirring member is provided such that the tip thereof is inclined toward the front side in the rotation direction at the time of forward rotation for stirring the garbage. In this way, during normal rotation, the garbage is scraped toward the center of the treatment tank, and during reverse rotation, the garbage is scraped outward from the center of the treatment tank. Agitation and discharge are possible.
In this case, it is preferable that both side portions of the wing portion are inclined backward in the rotation direction from the outside toward the inside. If it does in this way, since it acts so that garbage may be gathered in the center at the time of rotation, it becomes possible to improve discharge efficiency and to make the shape of a discharge port small.

  In addition, the present invention secondly, in the agitation member used in the garbage processing machine, which is installed over the opposing position of the treatment tank containing the garbage and which performs the agitation process of the garbage by the rotational drive by the driving means, the treatment tank A pair of bearing plate portions that are fixed to a pair of shaft portions disposed at opposite positions of the shaft portions and extend in a direction orthogonal to the axis of the shaft portions, and a wing portion that extends between the tip ends of the bearing plate portions. The stirring member characterized by this is provided.

In this stirring member, it is preferable that the wing portion is provided such that a tip thereof is inclined toward the front side in the rotation direction.
Moreover, it is preferable to provide a continuous plate part between the front-end | tips of the said bearing plate part, and to provide the said wing | blade part in the edge of this continuous plate part.
In this case, it is preferable that the continuous plate portion is provided so as to extend in a tangential direction with respect to the rotation locus. If it does in this way, the resistance at the time of rotation can be reduced and the crushing efficiency of garbage can be improved.
Alternatively, it is preferable to provide the continuous plate portion and the wing portion so as to extend flush with each other. In this way, a large amount of garbage can be moved, so that the stirring efficiency and the discharge efficiency can be improved.

  Moreover, it is preferable to provide the bearing plate part with a D-shaped attachment hole that penetrates the shaft part having a D-shaped cross section. In this way, the assembly workability of the stirring member can be improved, and the assembly state can be stabilized (rotation prevention).

  Furthermore, it is preferable that both side portions of the wing portion are inclined backward in the rotational direction from the outside to the inside. In this way, raw garbage can be collected in the center.

  In the garbage processing machine of the present invention, the garbage can be reliably agitated and crushed by rotating the stirring member in the normal rotation direction, and the garbage can be discharged from the discharge port to the waste container by rotating in the reverse direction. Moreover, since the stirring member is provided with a blade portion between the tips of the pair of bearing plate portions, there is no shaft in the center of the treatment tank. As a result, it is possible to prevent a reduction in the storage volume of the garbage and the agitation region while ensuring rigidity.

  The bearing plate portions 47A and 47B are arranged in a direction perpendicular to the shaft centers of the shaft portions 39A and 39B (that is, in the radial direction of the rotation locus). ) Is fixed so as to extend. The bearing plate portions 47A and 47B are provided with D-shaped mounting holes 48 having the same shape as the shaft portions 39A and 39B having a D-shaped cross section.

  The continuous plate portion 49 extends in a rectangular shape between the tip ends of the bearing plate portions 47A and 47B, and the direction (line) perpendicular to the left-right direction applied to the pair of shaft portions 39A and 39B is the tangential direction of the rotation locus. Configured to be located. Thus, the continuous plate portion 49 is configured not to have excessive resistance against garbage during rotation.

  The wing part 50 is provided in the continuous plate part 49 so as to extend between the front ends of the bearing plate parts 47A and 47B via the continuous plate part 49 by being connected to the front end edge with respect to rotation in the forward rotation direction.

  As shown in FIGS. 1 and 2, the processing tank 21 is provided with a fixed blade 52 having a concave shape in plan view so as to be positioned at the lower end of the rectangular tube-shaped upper portion 22. The fixed blade 52 has blade portions 53 at both ends positioned in the breaking groove 51 of the blade portion 50, and sandwiches the raw garbage placed on the blade portion 50 with the blade portion 53 when the stirring blades 46A and 46B rotate. Thus, the garbage is broken.

  Further, a pair of electrodes 54a and 54b (see FIG. 5) are disposed in the processing tank 21 as means for detecting the moisture content of raw garbage. When a predetermined voltage is applied to the electrodes 54a and 54b from a voltage application circuit (not shown), a current flows using garbage as a conductor, and the magnitude of the current is proportional to the resistance value. Since it is approximately proportional to the amount of moisture contained in the waste, the moisture content can be detected. The electrodes 54a and 54b serve as garbage detection means for detecting the presence or absence of garbage according to the energized state.

  In the garbage processing machine configured as described above, an operation panel 55 shown in FIG. 4 is disposed at a predetermined position on the front side. The operation panel 55 includes an ON / OFF switch 56 for operating or stopping the entire device, a temporary stop switch 57 for temporarily stopping the operation, and a state in which garbage is being processed by the stirring member 45 and the heater 30. In-process display 58 indicating that the waste container 37 is not attached, and a discharge switch 60 for discharging the garbage from the treatment tank 21 to the waste container 37. . The temporary stop switch 57 and the discharge switch 60 are provided with LEDs on the back to indicate the operation (execution) state of the switches 57 and 60 by turning on and off.

  As shown in FIG. 5, the microcomputer 61, which is a control means disposed on a control board (not shown), is operated according to a preset program by connecting a power outlet to a commercial power source. Specifically, when the user puts garbage into the processing tank 21 and turns on the ON / OFF switch 56 of the operation panel 55, the cover 11 of the insertion port 16 is closed by the microswitch 18. When garbage is detected, the garbage processing can be started.

  Then, the presence or absence of garbage is determined by the electrodes 54a and 54b, and when it is turned on, the garbage processing is executed. When it is not turned on, the power is automatically shut off after a predetermined time has elapsed. To stop. In the garbage processing, the electrodes 54a and 54b detect whether the garbage is in a dry state or an undried state. If the garbage is in an undried state, the garbage processing is executed. Dispose of processed garbage automatically. Further, when the discharge switch 60 is turned on, the state where the waste container 37 is mounted is detected by the micro switch 38 in the state where the garbage disposal is not performed, and the lid 11 of the input port 16 is closed. If so, the discharge process is executed.

  Next, the control by the microcomputer 61 will be specifically described.

  When power is turned on by the user operating the ON / OFF switch 56, the microcomputer 61 first executes input processing of the switches 56, 57, and 60 in step S1, as shown in FIG. In step S2, it is determined whether the operated switch is the discharge switch 60 or not. If it is not the discharge switch 60, the process proceeds to step S3. If it is the discharge switch 60, the process skips the following steps S3 to S11 and proceeds to step S12.

  In step S3, it is detected whether or not a pause is requested by operating the pause switch 57. If no temporary stop request has been made, the process proceeds to step S4. If a temporary stop request has been made, the process proceeds to step S5.

  In step S4, it is detected by the micro switch 18 whether the lid 11 has been opened. If the opening of the lid 11 is detected, the process proceeds to step S5. If the opening of the lid 11 is not detected, the process proceeds to step S8.

  In step S5, stop processing for stopping the operations of the agitating member 45, the heater 30, the fan 28, and the deodorizer 27 is executed, and then in step S6, the process waits until the closed state of the lid body 11 is detected by the microswitch 18. . When the closed state of the lid 11 is detected, in step S7, the process waits until the pause state is released. If the pause is released, the process proceeds to step S8.

  In step S8, garbage processing is performed by operating the stirring member 45, the heater 30, the fan 28, and the deodorizer 27, and the process returns to step S1. In this garbage disposal, the stirring member 45 is rotated forward so as to maintain a preset rotation speed by the motor 42. The heater 30 is on / off controlled so as to maintain a preset temperature control temperature based on the detection value of the thermistor 32. The fan 28 circulates the air in the processing tank 21 so as to maintain the air volume preset by the fan motor 29. The deodorizer 27 maintains the heating temperature by the catalyst heater at a preset temperature based on the detection value of the thermistor.

  Next, in step S9, the microcomputer 61 detects whether the garbage in the processing tank 21 is in a dry state by the garbage treatment based on the detection values of the electrodes 54a and 54b. Specifically, the detection values by the electrodes 54a and 54b are compared with a preset threshold value, and when the detection value has reached the drying threshold value, it is determined that it is in a dry state, and the drying threshold is determined. When the value has not been reached, it is determined that the state is undried. If it is determined that it is in a dry state, the process proceeds to step S10, and if it is determined that it is not in a dry state, the process returns to step S1.

  In step S10, an end process for stopping the operations of the agitating member 45, the heater 30 and the fan 28 is executed. In step S11, after the end process is finished, the temperature is set in advance in order to lower the temperature in the processing tank 21 to a predetermined temperature. It is detected whether the waiting (cooling) time has elapsed. If the standby time has elapsed, the process proceeds to step S12 to execute the discharge process. If the standby time has not elapsed, the process returns to step S1.

  Next, a discharge process after the end of the garbage process and a discharge process when the user operates the discharge switch 60 will be described.

  In this discharge process, as shown in FIG. 7, the microcomputer 61 first detects whether or not the garbage process of step S8 is being executed in step S20. If dust is being processed, the process proceeds to step S23, an error notification sound is output by the piezoelectric buzzer, and the process proceeds to step S29. If the garbage is not being processed, the process proceeds to step S21.

  In step S21, it is detected by the micro switch 38 whether or not the waste container 37 is attached. If the disposal container 37 is not attached, the process proceeds to step S23, an error notification sound is output by the piezoelectric buzzer, and the process proceeds to step S29. If the disposal container 37 is attached, the process proceeds to step S22.

  In step S <b> 22, it is detected whether or not the lid body 11 that closes the insertion port 16 is closed by the microswitch 18. If the lid 11 is not closed, the process proceeds to step S23, an error notification sound is output by the piezoelectric buzzer, and the process proceeds to step S29. If the lid 11 is closed, the process proceeds to step S24.

  In step S24, it is detected whether or not a flag f indicating the execution state of the discharge process is zero. If f is 0 (not executing), the process proceeds to step S25, and if f is 1 (executing), the process proceeds to step S28.

  In step S25, the agitating member 45 is rotated clockwise in FIG. 1 by rotating the motor 42 in the reverse direction. Then, in step S26, a discharge timer for measuring a preset discharge time is reset and started. Thereafter, in step S27, 1 is input to f to indicate that the discharge process is being executed.

  In step S28, it is detected whether or not the discharge timer has counted up. If the discharge timer has counted up, the process proceeds to step S29. If the count has not been counted up, the process returns to step S21.

  In step S29, the agitating member 45 is stopped by stopping the motor 42 and the discharging process is completed. Then, in step S30, 0 is input to f to indicate that the discharging process is stopped, and the process returns.

  When the waste that has been treated in this way is discharged from the treatment tank 21 to the disposal container 37, the user opens the cover 20 and removes the disposal container 37 from the opening 19. Thereafter, after the waste in the waste container 37 is discarded, the waste container 37 is again placed in the processor main body 10 through the opening 19.

  In this garbage disposal machine, the garbage can be reliably agitated and crushed by rotating in the forward direction, and the treated garbage can be discharged from the discharge port 33 to the waste container 37 by rotating in the reverse direction. Specifically, since the tip of the wing portion 50 is provided so that the tip thereof is inclined toward the front side in the rotation direction at the time of forward rotation that stirs the garbage, the garbage is removed from the treatment tank 21 at the time of forward rotation. It acts to scrape toward the center and acts to scrape the dust outward from the center of the processing tank 21 during reverse rotation, so that efficient stirring and discharging can be realized.

  Thus, since one stirring member 45 can have both a stirring function and a discharge function, it is possible to provide a garbage disposal machine that can be stirred and discharged at low cost without complicating the internal structure. Further, since the stirring blades 46A and 46B constituting the stirring member 45 are provided with the blade portion 50 between the tip ends of the pair of bearing plate portions 47A and 47B, the shaft does not exist in the center of the processing tank 21. Therefore, after ensuring the rigidity of the stirring member 45, it is possible to prevent the storage volume of the garbage and the reduction of the stirring area. In addition, it is possible to prevent inconvenience that garbage is caught in the shaft during stirring. As a result, it is possible to improve the processing efficiency of garbage.

  Further, in the stirring blades 46A and 46B constituting the stirring member 45, the continuous plate portion 49 provided with the blade portions 50 is provided so as to extend in a tangential direction with respect to the rotation locus, thereby reducing resistance during rotation. In addition, the efficiency of crushing garbage can be improved. Furthermore, since the D-shaped mounting holes 48 are provided in the bearing plate portions 47A and 47B of the stirring blades 46A and 46B, the directionality during the assembling work can be defined, so that the workability can be improved. Thus, it is possible to stabilize the assembled state (prevent rotation).

  FIG. 8 shows a garbage disposal machine according to the second embodiment. This garbage disposal machine is different from the first embodiment only in that the configuration of one stirring blade 46B constituting the stirring member 45 is changed.

  Specifically, as shown in FIG. 9, the stirring blade 46B includes a pair of bearing plate portions 47A and 47B in which a D-shaped mounting hole 48 is formed, as in the first embodiment. The bearing plate portions 47A and 47B are provided with a continuous plate portion 49 so as to extend between the tips. The continuous plate portion 49 of the second embodiment is configured such that the tip in the rotation direction is inclined forward and outward with respect to the rotation direction at the time of forward rotation for stirring and crushing raw garbage. Then, the wing portion 50 is provided on the leading edge of the continuous plate portion 49 so as to be flush with the continuous plate portion 49, so that the tip portion is rotated with respect to the rotation direction when the wing portion 50 is rotated forward. And are configured to incline forward and outward. In other words, the stirring blade 46B of the present embodiment is provided with the blade portion 50 having the integral continuous plate portion 49 between the tips of the bearing plate portions 47A and 47B.

  In the agitating blade 46B of the second embodiment configured as described above, as in the first embodiment, during the normal rotation for stirring the garbage, it acts to scrape the garbage toward the center of the processing tank 21. On the other hand, at the time of reverse rotation for discharging the treated dust, the dust is scraped outward from the center of the treatment tank 21. Moreover, in the present embodiment, since the continuous plate portion 49 and the wing portion 50 are provided flush with each other, the contact area with the garbage increases, and a large amount of dust can be moved.

In the third embodiment, the configurations of the blade portions 50A and 50B are different from those in the first embodiment, and the stirring blades 46A and 46B are also different in configuration.

  As shown in FIG. 11 (A), the blade portion 50A of the stirring blade 46A located on the right side in FIG. 10 has a break groove 51 for inserting the same fixed blade 52 as in the first embodiment as a boundary. It is divided into a plate portion 62A and plate portions 62B and 62C on both sides thereof. And 62 A of board parts are comprised so that the front-end | tip may incline forward outward with respect to a rotation direction at the time of forward rotation. Further, the plate portions 62B and 62C on both sides located in the vicinity of the bearing plate portions 47A and 47B have their tips inclined forward and outward with respect to the rotation direction during forward rotation, and from the outer edge to the inner side. It is provided so as to be inclined obliquely so that the inner edge is located on the rear side in the rotational direction (to the side of the plate portion 62A). As a result, the plate portions 62B and 62C of the wing portion 50A act so as to collect garbage in the center during forward rotation. On the other hand, since the outer edge is located on the rear side in the rotation direction during the reverse rotation, the dust acts on both sides.

  As shown in FIG. 11B, the blade portion 50B of the stirring blade 46B located on the left side in FIG. 10 is divided into a central plate portion 63A and plate portions 63B and 63C on both sides, like the blade portion 50A. The center plate portion 63A is configured such that the tip end thereof is inclined forward and outward with respect to the rotation direction during forward rotation. The plate portions 63B and 63C on both sides located in the vicinity of the bearing plate portions 47A and 47B are inclined forward and outward with respect to the rotation direction during forward rotation, and the inner side (the plate portion 63A). The outer edge is provided so as to be inclined obliquely from the side edge toward both outer edges so that the outer edge is located on the rear side in the rotation direction. As a result, the plate parts 63B and 63C of the wing part 50B act so as to scrape garbage into both sides during forward rotation. On the other hand, during reverse rotation, the inner end edge is located on the rear side in the rotation direction, and thus acts to collect dust in the center.

  In the stirring member 45 of the third embodiment configured as described above, the blade portions 50A and 50B of the stirring blades 46A and 46B act so as to gather raw garbage toward the center of the processing tank 21 or collect dust. It acts to scrape outward from the center of the treatment tank 21. Therefore, it is possible to prevent unbalanced garbage and to efficiently stir and discharge. Specifically, at the time of forward rotation for stirring the garbage, the blade portion 50A of the stirring blade 46A acts to gather the garbage toward the center of the processing tank 21. On the other hand, the blade portion 50B of the stirring blade 46B acts so as to scrape the garbage outward. And since these gathering actions and scraping actions combine, the garbage in the processing tank 21 can be stirred uniformly, so that the stirring efficiency can be improved. On the other hand, at the time of reverse rotation for discharging the treated dust, the blade portion 50B of the stirring blade 46B acts to send the treated dust outward while being scraped toward the center of the treatment tank 21. Therefore, since the efficiency of discharging to the discharge port 33 can be improved, the opening area of the discharge port 33 can be reduced.

  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, in the second embodiment, the stirring member 45 is configured by using different stirring blades 46A and 46B, but the stirring member 45 may be configured by a pair of stirring blades 46B and 46B. Similarly, in 3rd Embodiment, the stirring member 45 may be comprised by a pair of stirring blade 46A, 46A, and the stirring member 45 may be comprised by a pair of stirring blade 46B, 46B.

  Of course, the stirring blades 46A and 46B of the first embodiment, the stirring blades 46B of the second embodiment, and the stirring blades 46A and 46B of the third embodiment may constitute the stirring member 45 in various combinations as desired. it can. In addition, the stirring member 45 is not limited to the combination of the pair of stirring blades 46A and 46B, and can be configured by combining three or more stirring blades by changing the formation angle of the attachment hole 48.

  Furthermore, in each said embodiment, although the stirring member 45 which consists of a pair of stirring blade 46A, 46B was applied to the garbage processing machine equipped with the discharge function, it applied to the garbage processing machine which is not equipped with the discharge function. Even in this case, as described above, the rigidity of the stirring member 45 can be secured, and the storage volume of the garbage and the stirring area can be prevented from being reduced. In addition, it is possible to prevent inconvenience that garbage is caught in the shaft during stirring. As a result, it is possible to improve the processing efficiency of garbage.
