Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a drying device that simply dries cooking scraps such as unnecessary portions of foods from homes and commercial stores, so-called raw garbage.
[0002]
[Prior art]
Conventionally, cooking scraps such as unnecessary portions of ingredients from homes and commercial stores are mostly discarded as raw garbage.
However, recently, as seen in ecology, garbage disposal problems, recycling laws, etc., efforts have been made to recycle organic waste as an organic fertilizer rather than simply throwing away garbage.
As part of this, various garbage processing apparatuses have been developed, and there are small garbage processing apparatuses intended for general households and large garbage disposal apparatuses intended for stores.
And even in fast-food stores that are chained, efforts are being made to process cooking scraps (mainly vegetable scraps) from the stores themselves and recycle them as organic fertilizers.
[0003]
By the way, the amount of cooking waste from a relatively small store such as a fast food store with such a chain development is small enough to install and process the above-mentioned large garbage disposal device in each store. In addition, it is not easy to secure a place for installing such a large apparatus, which is an amount that cannot be processed by the small household garbage processing apparatus described above.
For this reason, chain-developed fast food stores sometimes adopt a method in which cooking waste from each store is collected at a collection station and put into a large processing unit consisting of a bio-type decomposition tank to produce organic fertilizer. Many.
[0004]
[Problems to be solved by the invention]
However, it is possible to install a common collection station as used in the above-mentioned chain-developed fast food stores, and to transfer the cooking waste from each store to the collection station every time it is generated. It is time consuming and wasteful.
Therefore, it is more efficient if it is possible to store cooking waste at each store to some extent and then transport it to the collection station.However, if the storage period of cooking waste at each store is extended in this way, it becomes unsanitary due to water separation and rot. There is a problem that there is also a smell. Moreover, when cooking waste containing a large amount of water separation is put into a bio-type decomposition tank, there arises a problem that the processing capacity of the decomposition tank is hindered.
[0005]
Therefore, the present invention is made to solve the above-mentioned problems, and the object of the present invention is to easily dry cooking waste stored in each store without taking up space, and to easily recycle cooking waste as organic fertilizer. It is in providing the drying apparatus which can do.
[0006]

[0011]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, preferred embodiments of a drying apparatus 10 according to the present invention will be described in detail with reference to the accompanying drawings.
First, the structure of the drying apparatus 10 is demonstrated using FIGS.
The main body 12 is formed in a shape that can be placed by placing the opening 14a in the opening 14a of the can 14 having an upper opening. In the case of the drying apparatus 10 of the present embodiment, the can body 14 is assumed to be a pail can that is widely distributed. For this reason, the main body 12 is formed in a cylindrical body having a larger diameter than the outer diameter of the opening 14a in accordance with the shape of the opening 14a of the pail can having a cylindrical outer shape (the planar shape is circular).
[0012]
The lower surface 12a of the main body 12 has a function of directly contacting the opening 14a mouth edge of the can body 14 and covering the opening 14a. And the microwave for drying the cooking waste 16 accommodated in the inside of the can body 14 is irradiated toward the inside of the can body 14 from the main-body part 12. As shown in FIG. And in order to prevent this microwave from leaking outside from the opening part 14a, the lower surface 12a of the main-body part 12 is comprised with the material which can shield a microwave, and functions as a shielding cover.
Further, a cylindrical skirt portion 18 extending downward is formed on the lower outer peripheral surface of the main body portion 12 so as to extend downward so that the inner peripheral surface faces the upper outer peripheral surface of the can body 14. The skirt portion 18 is also made of a material capable of shielding microwaves, and functions as a shielding plate that suppresses leakage of microwaves from the opening portion 14 a of the can body 14 that is closed by the lower surface of the main body portion 12.
[0013]
Further, in the present embodiment, a plurality of guide pieces 20 (preferably three or more) are extended on the outer peripheral side of the lower surface 12 a of the main body 12, and a disc as a second shielding lid is provided between the guide pieces 20. The body 22 is held away from the lower surface 12a and parallel to the lower surface 12a. Since the disc body 22 is further provided as a shielding lid, leakage of microwaves from the opening 14a of the can body 14 is further reduced. Note that the disc body 22 and the skirt portion 18 are not essential components, and may be provided as necessary.
Further, each guide piece 20 is provided so as to be positioned on a virtual circumference having a diameter smaller than the inner diameter in accordance with the inner diameter of the opening 14 a of the can body 14, and the main body portion 12 is provided with the opening 14 a of the can body 14. It functions as a guide when attaching to the camera. That is, when the main body 12 is attached to the opening 14a of the can body 14, the main body 12 is positioned after the main body 12 is positioned with respect to the can 14 so that all the guide pieces 20 are inside the opening 14a. It is moved downward and placed in the opening 14 a of the can 14. Thereby, the center of the cylindrical main body portion 12 can be reliably positioned near the center of the cylindrical can body 14.
[0014]
In addition, a pair of grip portions 24 are provided on the upper surface of the main body portion 12 so that the main body portion 12 can be easily held by hand. Further, an engagement hook 26 is attached to the outer peripheral surface of the main body portion 12 so that its root portion can be freely rotated by a screw, a rivet or the like, and a tip formed in a hook shape can swing. The engaging hook 26 is used when the main body 12 is fixed to the can 14 after the main body 12 is placed in the opening 14 a of the can 14. The tip of the shape is engaged with the base portion 28 a of the handle 28 provided on the can body 14. By engaging the engagement hook 26 with the handle 28 of the can body 14, it is possible to prevent the main body portion 12 from rotating in the reverse direction with respect to the can body 14 due to a reaction when a stirring means described later rotates. .
An intake port 30 and an exhaust port 32 are provided on the outer peripheral surface of the main body 12.
Reference numeral 34 denotes an air vent for leading the steam 36 emitted from the cooking scraps 16 to the outside of the can 14, and the exhaust port 32 of each main body 12 of the disc body 22 and the lower surface 12 a of the main body 12. It is provided in the part near.
[0015]
The first electric motor 37 as the rotation driving means is provided inside the main body 12, and its output shaft 38 is disposed on the axis of the main body 12, and the lower surface 12 a of the main body 12 and the disc body 22. And the tip protrudes from the disc body 22. It is also possible to combine the first electric motor 37 and the reduction gear mechanism to reduce the rotation of the output shaft 38 and increase the rotational torque.
The microwave generating means 40 is provided in the main body 12, and the irradiation port of the waveguide 42 that opens to the disk body 22 through the waveguide 42 that penetrates the lower surface of the main body 12 and the disk body 22. The microwave 40a is irradiated into the can 14 from 42a.
In the present embodiment, the main body 12 includes a fan 44 for cooling the first electric motor 37, the microwave generation means 40, a control means described later, and the like, and a second electric motor that rotationally drives the fan 44. A motor 46 is also provided.
[0016]
The main body 12 is provided with a detecting means 48 for detecting that the main body 12 is placed on the opening 14 a of the can 14. As an example, the detection means 48 is slidable on the lower surface 12a of the main body 12 and is disposed so as to pass through the lower surface 12a so as not to drop downward, and has a lower end protruding from the lower surface 12a. The detection pin 48a is always urged in the direction in which the detection pin 48a protrudes from the lower surface 12a, and when the detection pin 48a is pushed into the lower surface 12a by a predetermined amount, the detection pin 48a The limit switch 48b is switched from OFF to ON when pressed. The detection means 48 is not limited to this configuration, and various configurations such as a configuration using an optical sensor or a proximity switch can be employed.
When the main body 12 is placed on the opening 14a of the can body 14 by the detection means 48, the detection pin 48a is pushed into the main body 12 by the weight of the main body 12 at the opening 14a rim, Since the limit switch 48b is turned on from off and the state of the limit switch 48b is detected, it is possible to detect that the main body 12 is placed on the can 14. This is because the output shaft 38 protruding from the main body 12 is prevented from rotating in an exposed state and the safety is improved.
[0017]
An operation switch 50, a stop switch 52, and an operation time setting timer 54 are disposed on the upper surface of the main body 12, and a control unit 56 is disposed inside the main body 12.
The control means 56 is configured using a sequencer, a CPU, and the like, and controls the operation of the electric motors 37 and 46 and the microwave generation means 40 based on the states of the detection means 48, the operation switch 50, the stop switch 52, and the timer 54. . In summary, the control means 56 activates the operation switch 50 only when it detects that the main body 12 is placed on the opening 14a of the can body 14 via the detection means 48, and the electric motors 37, 46, Control is performed so that the microwave generation means 40 can be operated. Details of the operation will be described later.
[0018]
The stirring means 58 has an upper end that is detachably connected to the output shaft 38 and is rotatable integrally with the output shaft 38, and a wing body 62 that is attached to the shaft body 60 and extends laterally. Have The stirring means 58 is formed separately from the main body 12, is inserted into the can body 14, and rotates inside the can body 14. And it is thrown in in the can 14 by the feather body 62, and the accumulated cooking waste 16 is stirred.
In the present embodiment, the two wings 62 described above are provided as an example, extend laterally from the outer peripheral surface near the lower end of the shaft body 60, rotate at a portion near the bottom surface 14 b of the can body 14, and cook scraps. 16 can be stirred from the bottom.
[0019]
In the present embodiment, the agitating means 58 is located above the wing 62 and extends radially from the shaft 60 to prevent the agitating means 58 from tilting in the can 14. 64 is provided as an example.
The aforementioned wings 62 and the second wings 64 extend at right angles to the shaft body 60 as an example, and the diameter of the circular locus drawn by the tips of the wings when rotating about the shaft body 60 is a can body. It is formed so as to be smaller than the inner diameter of 14. In addition, the wing body 62 and the second wing body 64 may be configured to extend directly from the outer peripheral surface of the shaft body 60, but in the present embodiment, the wing body 62 and the second wing body 64 are attached to a ring body 66 that can be externally fitted to the shaft body 60. The ring body 66 is externally fitted to the shaft body 60, moved to a predetermined position along the axial direction of the shaft body 60, and the ring body 66 is fixed to the shaft body 60 by means such as a screw, thereby the shaft body 60. Attached to.
[0020]
In addition, the drying apparatus 10 of the present embodiment has a shape that can be laid on the inner bottom surface of the can body 14 (slightly smaller than the inner diameter of the can body 14), and a shaft that corresponds to the output shaft 38 on the top surface. A base portion 68 is provided in which a bearing 70 is formed which is fitted to the lower end 60a of the body 60 and rotatably supports the shaft body 60.
By providing the base portion 68 and the bearing 70, it is possible to effectively prevent the lower end of the shaft body 60 from being shaken when the shaft body 60 is rotated, and efficient stirring is possible.
In particular, in the present embodiment, the agitating means 58 is connected to the output shaft 38 at the connected portion even after the upper end of the shaft body 60 and the lower end of the output shaft 38 are in a connected state, as will be described later. Can be bent. Therefore, if the base portion 68 is not present, the lower end of the shaft body 60 is in a free state, and the stirring means 58 cannot be rotated well with the axis of the shaft body 60 aligned with the axis of the output shaft 38. .
Therefore, a structure for supporting the lower end of the shaft body 60 is necessary.
[0021]
Next, the structure of the coupling mechanism 72 provided between the lower end of the output shaft 38 and the upper end of the shaft body 60 will be described.
First, as shown in detail in FIG. 3, the structure of the output shaft 38 is such that the outer peripheral surface on the distal end side is formed into a tapered surface that gradually becomes smaller in diameter toward the distal end, and is slightly larger than the region A formed on the tapered surface. Engagement pins 38a project from the upper outer peripheral surface toward the side. A pair of engaging pins 38 a are provided at point-symmetric positions with respect to the axis of the output shaft 38. By forming the outer peripheral surface on the front end side of the output shaft 38 into a tapered surface, the output shaft 38 can be smoothly introduced and inserted into the connecting cylinder provided at the front end of the shaft body 60 described later.
[0022]
Next, the structure of the upper end of the shaft body 60 will be described with reference to FIG.
In the upper part of the shaft body 60, one guide long hole 60 a is formed that extends along the axial direction of the shaft body 60 and passes through the shaft body 60 through the axis.
The upper part of the shaft body 60 is inserted into the connecting cylinder 74. On the lower side of the connecting cylinder 74, a pin insertion hole 74a passing through the connecting cylinder 74 through the axis of the connecting cylinder 74 is opened, and the pin insertion hole 74a and the guide long hole 60a are formed. In the state of communication, a rotation preventing pin 76 is mounted in the pin insertion hole 74a so as to penetrate the guide long hole 60a. As a result, the connecting cylinder 74 and the shaft body 60 are arranged so that the connecting cylinder 74 fitted on the upper portion of the shaft body 60 is within the range in which the rotation prevention pin 76 can move within the guide long hole 60a. It is connected so that it can move along the axis of the body 60 and can rotate integrally. The total length of the rotation prevention pin 76 is set to a length that does not protrude from the pin insertion hole 74a at both ends.
Further, an engagement recess 74 b into which each engagement pin 38 a provided on the output shaft 38 is fitted is formed at the upper end of the connecting cylinder 74.
Further, the outer diameter of the lower side region B including the portion where the pin insertion hole 74a of the connecting cylinder 74 is opened is formed to be slightly smaller than the upper side, and the whole is a two-stage cylinder.
[0023]
An outer cylinder 78 for closing the pin insertion hole 74 a in which the detent pin 76 is inserted is provided in the lower side region B formed in the small diameter of the connecting cylinder 74. It is slidably fitted on the surface. A flange portion 78a is formed over the entire outer peripheral surface of the upper cylindrical body 78 formed in a cylindrical shape.
Further, a coil spring 80 as an urging means is attached to the outer cylinder 78 and the shaft body 60 between the upper surface 66a of the ring body 66 to which the second wing body 64 is attached and the flange portion 78a of the outer cylinder 78. It is mounted in a state of being fitted and contracted. The coil spring 80 always urges the outer cylinder 78 upward with respect to the ring body 66, but the upper opening edge of the outer cylinder 78 is formed at the boundary of the region B of the connecting cylinder 74. The contact with the stepped portion 74c restricts upward movement and prevents the connecting cylinder 74 from coming off. When an external force in the direction of the ring body 66 (downward) is applied to the connecting cylinder 74, the coil spring 80 is elastically deformed, so that the connecting cylinder 74 is guided in the ring body 66 direction and the non-rotating pin 76 is guided. It can move until it contacts the lower end of the long hole 60a. When no external force is applied, the connecting cylinder 74 is moved upward via the outer cylinder 78 by the urging force of the coil spring 80, and the detent pin 76 contacts the upper end of the guide slot 60a. Is in a state.
[0024]
By the connecting mechanism 72 described above, the connecting cylinder 74 can move in the vertical direction within the range of the length of the guide long hole 60a, and the protruding length of the output shaft 38 from the disc body 22 or the axial length of the shaft 60 Even when a slight assembly error occurs, the engagement pin 38a of the output shaft 38 and the engagement recess 74b of the connecting cylinder 74 are reliably engaged.
The connection mechanism 72 does not necessarily have the configuration shown in FIG. 4. For example, when the above-described assembly error is small, only the connection cylinder 74 is fixed to the upper part of the shaft body 60. A structure may be adopted. In addition, although not shown, if the outer diameter of the shaft body 60 is sufficiently large, a structure in which the engaging recess 74b is formed directly on the upper end of the shaft body 60 may be employed.
[0025]
Next, the operation / use method of the drying apparatus 10 will be described.
First, the user inserts the stirring means 58 into the empty can 14 in advance. The agitation means 58 is provided with not only the wing body 62 but also the second wing body 64 on the upper side of the shaft body 60. When the agitation means 58 falls down even slightly, the tip of the second wing body 64 becomes the inner periphery of the can body 14. Touch the surface. Thereby, the stirring means 58 is maintained in a state of hardly tilting (not tilting), and the shaft body 60 is positioned at the approximate center of the can body 14 formed in the cylindrical body.
Next, the user sequentially puts cooking scraps 16 from the store into the can 14.
[0026]
And if the cooking waste 16 accumulates in the can 14 to some extent, it is necessary to dry the cooking waste 16.
Therefore, the user places the main body 12 on the opening 14a of the can 14 so as to close the opening 14a. At this time, the main body 12 is first positioned so that each guide piece 20 that protrudes most from the lower surface 12 a of the main body 12 enters the opening 14 a of the can 14. In this state, the main body 12 is lowered and placed on the can 14. Since the shaft body 60 of the stirring means 58 is positioned at the approximate center of the can body 14, the output shaft 38 projecting to the center of the lower surface 12 a of the main body portion 12 positioned with respect to the can body 14 by the guide piece 20 is ensured. It can be fitted into the engaging recess 74 b of the connecting cylinder 74 at the top of the stirring means 58. The detection means 48 detects that the limit switch 48b is turned on when the main body portion 12 is placed in the opening 14a of the can body 14, and indicates that the main body portion 12 is placed on the can body 14. Output a signal.
[0027]
Next, the user operates the operation switch 50 provided on the upper surface of the main body unit 12 to change from the off state to the on state.
In the control means 56, the operation switch 50 is turned on in a state where the detection means 48 detects that the main body portion 12 is placed on the opening 14 a of the can body 14 by inputting the detection signal. When this is detected, the electric motor 37 is operated to stir the cooking waste 16 in the can 14. At the same time, the microwave generating means 40 is operated to start irradiation of the microwave 40a into the can 14. Further, the second electric motor 46 is operated to rotate the cooling fan 44, and the components arranged in the main body 12 are cooled.
[0028]
The cooking waste 16 is stirred by the wing body 62 while being heated by the irradiation of the microwave 40a, whereby the moisture contained therein is efficiently evaporated. Then, the steam 36 moves to the inside of the main body portion 12 through the disk body 22 and the vent hole 34 provided in the lower surface 12 a of the main body portion 12. An air flow (indicated by a solid line) is generated in the main body 12 in which outside air is introduced from the intake port 30 by the rotation of the fan 44 and this outside air is exhausted to the outside again from the exhaust port 32. . The steam 36 that has entered the inside of the main body 12 is discharged from the exhaust port 32 to the outside of the main body 12 by the flow of air. Moreover, the vapor | steam 36 which entered in the main-body part 12 by the flow of this air is spread | diffused, and it can prevent that the exhaust port 32 vicinity dew condensation or a water droplet adheres to the exhaust port 32 vicinity.
The above is the description of the drying operation, and the cooking waste 16 is dried by this drying operation.
The user can arbitrarily stop the drying operation by operating the stop switch 52.
Since the volume of the dried cooking waste 16 is reduced, a large amount of cooking waste 16 can be stored in the can 14, the number of times of transportation to the collecting station can be reduced, and cooking discarded in the can 14 by drying. The scrap 16 can be prevented from water separation and decay, the inside of the store does not smell, and the disassembly at the accumulation station can be performed smoothly.
[0029]
The control means 56 monitors the setting state of the timer 54 by the user, and when the timer 54 is set, determines that the ON state of the operation switch 50 is valid for the time set by the timer 54. A drying operation is performed, and when the set time is over, the drying operation is forcibly stopped. Therefore, the user can operate the timer 54 to perform a drying operation for a set time, and thereafter automatically terminate the drying operation. The set time may be determined in consideration of the amount of cooking waste.
[0030]
【The invention's effect】
When using the drying apparatus according to the present invention, it exists as an empty can that has been used in various stores, for example, a pail can etc. can be used as a can body, and the drying apparatus can be configured simply, saving space, and It becomes possible to easily store cooking waste generated at a store for each store. Therefore, the number of times of conveyance to the accumulation station can be reduced, which is efficient, and the cooking debris at the accumulation station is smoothly decomposed by drying the cooking debris.
