Abstract

<P>PROBLEM TO BE SOLVED: To reduce the occurrence of trouble produced when undue force is applied to an opening/closing mechanism through a garbage charging part. <P>SOLUTION: This garbage feeding mechanism comprises a rotary drum 30 feeding garbage from the inlet 25 of the garbage into a garbage storage part by rotating. The rotary drum 30 is supported rotatably by a driving roller 40 in contact with the peripheral surface of the rotary drum. When the rotation of the rotary drum 30 is stopped by any reason, even if a user applies a forcibly rotating force thereto, the rotating drum 30 slips on the drive roller 40 and rotates alone. Accordingly any undue force is not applied to the motor 50 driving the drive roller 40, and the frequency of troubles can be reduced. <P>COPYRIGHT: (C)2005,JPO&NCIPI

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a trash can provided in a trash can and a trash can using the trash can.
[0002]
[Prior art]
For example, Patent Literature 1 discloses a trash can in which a lid member provided on an upper portion of a trash container is electrically opened and closed. This is a mechanism in which a sensor or the like is provided in the upper part of the trash box, and the lid member automatically opens and closes when a person approaches or holds a hand.
[0003]

JP-A-11-292208
[Problems to be solved by the invention]
Since the above-mentioned trash can is electrically driven, for example, even when a large amount of trash is stored in the trash storage unit, the motor attempts to drive when a sensor detects the approach of a person or the like. For this reason, if a large amount of dust is stored, the dust may be caught by the rotating mechanism of the lid member and may be forced to rotate while applying excessive force, which may cause a failure or the lid member may not be completely closed. In addition, when a person forcibly presses the lid member, an excessive force is applied to the motor, and the motor may break down. However, such problems are unlikely to occur if management is performed so that the amount of garbage in the garbage storage unit is always kept below the standard.However, users may concentrate on a certain period of time and increase sharply. It is virtually impossible to keep the capacity below a predetermined reference at all times.
For this reason, in the case of an electric trash can, there has been a demand for the development of a mechanism capable of minimizing the adverse effect on the motor even if trash is caught or a person tries to operate the trash can due to the above factors.
[0005]
In order to enhance the sanitary condition of the trash box itself, it is desirable to periodically clean the lid member and the trash container that frequently contact the trash. However, in the case of the one disclosed in Patent Literature 1, although the dust container can be easily cleaned, when cleaning a lid member, a tray, and the like that constitute a dust feed mechanism for feeding dust into the dust container, It is necessary to remove them together with the frame members holding them. Since the lid member, the tray, and the like are attached via the hinge mechanism, it takes time and effort to remove and wash them alone.
[0006]
The present invention has been made in view of the above, and it is possible to reduce the adverse effect on the motor as much as possible, reduce the frequency of failures, and easily remove and clean the trash can even if trash is caught or a person tries to force operation. It is an object of the present invention to provide a garbage feed mechanism and a trash box using the garbage feed mechanism.

BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, the present invention will be described in more detail based on the embodiments shown in the drawings. FIG. 1 is a cross-sectional view showing the internal structure of a dust feeding mechanism 10 according to one embodiment of the present invention, and FIG. 2 is a perspective view seen from the front. As shown in these drawings, the dust feeding mechanism 10 of the present embodiment includes a frame member 20, a rotating drum 30, a driving roller 40, and a motor 50.
[0009]
The frame member 20 includes a front plate portion 21, a back plate portion 22, and two opposing side plate portions 23. These are formed in a substantially rectangular frame shape when viewed from below, and the front plate portion 21 rises linearly from the lower end when viewed from the side plate portion 23 direction, and then forms a circular arc-shaped rear direction. The rear plate portion 22 is formed so as to bend substantially and rise up further, and the back plate portion 22 rises substantially linearly from the lower end. The lower end is opened, and is detachably attached to the upper part of the dust container 100 via the lower end opening 24 so that the lower end opening 24 and the upper end opening 101 of the dust container 100 communicate with each other. .
[0010]
Further, in a portion of the front plate portion 21 located above the lower end opening portion 24, a portion formed in an arc shape has an opening length along the arc in the width direction between the side plate portions 23, 23. Along the opening, the opening is a substantially rectangular shape as viewed from the front.
[0011]
The rotary drum 30 is formed in a substantially cylindrical shape, and is disposed in the frame member 20 along the width direction, that is, with the axial direction along the direction in which the side plates 23 and 23 face each other. The rotating drum 30 includes a dust receiving portion 31 which is cut out in a groove shape along the axial direction on a peripheral surface thereof. More specifically, the dust receiving portion 31 is cut out in a substantially fan shape when viewed from the side as shown in FIGS. It has crossing groove wall surfaces 31a and 31b, and is configured to receive dust introduced by the groove wall surfaces 31a and 31b. As shown in FIGS. 4A and 4B, the intersection of the groove wall surfaces 31a and 31b is viewed from the outer peripheral arc of the substantially fan-shaped dust receiving portion 31 with respect to the rotation center P of the rotary drum 30. Preferably, the position is eccentric to the back side. As a result, the area of the groove wall surface 31a or 31b can be increased as compared with the case where the intersection position of the groove wall surfaces 31a and 31b coincides with the rotation center of the rotary drum 30. Can be increased.
[0012]
Further, the cutout length of the dust receiving portion 31 of the rotary drum 30 along the arc, that is, the length of the outer peripheral arc is preferably substantially the same as the opening length of the inlet 25 along the arc (FIG. 1). reference). Thus, when the dust receiving portion 31 faces the input port 25, the size of the input port 25 is not substantially reduced.
[0013]
The dust receiving portion 31 formed on the rotating drum 30 is formed over the entire length in the axial direction in view of the easiness of processing, but a driving roller 40 described later needs to contact the peripheral surface of the rotating drum 30. For this reason, caps 32, 32 are attached to each end in the axial direction so that they can come into contact with each other even in a range where the dust receiving portion 31 is formed. Of course, when manufacturing the rotating drum 30, it is also possible not to form the notch serving as the dust receiving portion 31 only near each end in the axial direction. In this case, it is not necessary to attach the caps 32, 32. Absent.
[0014]
The drive roller 40 is provided so that the outer surface of the roller can come into contact with the peripheral surface of the rotary drum 30, and transmits the rotational force of the drive roller 40 to the rotary drum 30 by friction to rotate the rotary drum 30. In the present embodiment, as shown in FIGS. 1 and 2, the drive roller 40 is located near the lower end opening 24 of the frame member 20 and near one of the side plate portions 23, near the front plate portion 21. And the rear plate 22 side. The rotating drum 30 is supported by arranging it on the driving roller 40 so that the peripheral surface of one cap 32 of the rotating drum 30 is in contact with the driving roller 40. In order to make the rotating drum 30 rotatable when the driving roller 40 comes into contact with the peripheral surface of the rotating drum 30, a portion that rotates while contacting the peripheral surface of the rotating drum 30 and that is located near the lower portion of the rotating drum 30 is required. A supporting member is required. In the present embodiment, the two drive rollers 40 also function as members that support the rotary drum 30. However, since the other end of the rotary drum 30 cannot be supported only by the drive roller 40 provided only in the vicinity of the one side plate portion 23, in the present embodiment, as shown in FIG. In the vicinity of the side plate portion 23, support rollers 45 having the same height as the drive roller 40 and having a function of only supporting the rotary drum 30 are provided on the front plate portion 21 side and the back plate portion 22 side. And the other cap 32 is contacted and supported.
[0015]
The drive roller 40 only needs to be able to rotate the rotary drum 30 by friction, and the drive roller 40 may be one as long as it can rotate smoothly. Further, for example, the four rollers arranged near the lower end opening 24 of the frame member 20 are all constituted by support rollers, and the driving roller 40 is arranged near the upper part of the peripheral surface of the rotating drum 30 (cap 32). It can also be provided so as to be able to come into contact with the located part.
[0016]
In the present embodiment, the motor 50 is provided in the space above the rotary drum 30 in the frame member 20. A drive belt 52 is wound around a drive roller 40 between a rotation output unit 51 such as an output shaft and a gear of the motor 50 and the drive roller 40, and the power of the motor 50 is transmitted to the drive roller 40. In this embodiment, as shown in FIG. 1, since two drive rollers 40 are used, two drive belts 52, 52 are wrapped around the rotation output unit 51, and the two drive rollers 40, 40 The motor 50 rotates in the same direction. In addition, the arrangement position of the motor 50 is not limited, and may be arranged in an empty space in the frame member 20. For example, it can be provided in a side space of the rotating drum 30. Further, depending on the arrangement position of the motor 50, the drive roller 40 may be directly connected to the rotation output unit 51 of the motor 50 without passing through the drive belt 52.
[0017]
The power source of the motor 50 is arbitrary, but in this embodiment, a battery 55 is used. Further, although the drive switch of the motor 50 is also optional, in the present embodiment, a detection sensor 56 such as an optical sensor is provided near the upper part of the front plate portion 21 and a person holds the detection sensor 56 by holding a hand. , The motor 50 is driven. Of course, it is also possible to adopt a structure in which the motor 50 is driven using another switch such as a push button.
[0018]
Further, a control circuit for controlling the rotation amount of the rotating drum 30 is connected to the motor 50. This control circuit includes a position sensor 57 for detecting a reference position in the rotation direction of the rotary drum 30. In a normal operation, when the rubber receiver 31 rotates, for example, by a predetermined angle from the reference position, the rubber receiving portion 31 faces the insertion port 25. For example, it is configured to stop for a few seconds while receiving dust from the input port 25. Thereafter, when the rotary drum 30 further rotates by a predetermined angle, the outer peripheral surface 33 of the rotary drum 30 on which the dust receiving portion 31 is not formed faces the inlet 25. In the normal operation, the position sensor 57 detects the reference position, for example, every time the rotating drum 30 makes one revolution. However, the detection of the reference position by the position If the time is not longer than the predetermined time, it is preferable that the control circuit outputs a signal for stopping the driving to the motor 50. Further, even when the position sensor 57 does not detect that the reference position has stopped at the predetermined position for a predetermined time or more, that is, when the rotation of the rotating drum 30 does not stop for a predetermined time or more, there is a possibility that some trouble has occurred. Therefore, it is preferable to output a signal for stopping the driving of the motor 50.
[0019]
Next, the operation of the dust feeding mechanism 10 according to the present embodiment will be described. The dust feed mechanism 10 is mounted such that the lower end opening 24 of the frame member 20 is communicated with the upper end opening 101 of the dust container 100 as shown in FIG. Is done.
[0020]
In the non-use state, the rotary drum 30 of the dust feeding mechanism 10 is set such that the outer peripheral surface 33 on which the dust receiving portion 31 is not formed faces the inlet 25 (solid line in FIG. 1, FIG. 4B). And the state of FIG. 5 (a)). Thereby, the inside of the trash box 110 including the trash feeding mechanism 10 and the trash container 100 is not seen from the outside, and a clean feeling is given. On the other hand, when the detection sensor 56 detects that the user is approaching, or when the user puts his hand over the detection sensor 56, the motor 50 is driven, the drive roller 40 is rotated in a predetermined direction, and the position sensor 57 is When it is detected that the receiving portion 31 has reached the position facing the insertion port 25, the rotation of the rotary drum 30 stops for a few seconds (the imaginary line in FIG. 1, the state shown in FIGS. 4A and 5B). ). During this time, the user puts dust into the dust receiving portion 31 through the slot 25. Then, when a predetermined stop time elapses or when the detection sensor 57 detects that the user has left, the rotating drum 30 is rotated again by the motor 50 and the driving roller 40.
[0021]
Since the dust receiving portion 31 of the rotating drum 30 faces the upper end opening 101 of the dust containing portion 100 during the rotation, dust falls into the dust containing portion 100 and is stored therein. When a predetermined amount of dust is stored, the dust feeding mechanism 10 is removed from the dust storage unit 100, and the dust in the dust storage unit 100 is discarded.
[0022]
On the other hand, if the operation of the rotating drum 30 is different from the normal operation and continues to rotate or is stopped, as described above, the signal from the position sensor 57 is output as described above. Then, a stop signal is sent from the control circuit to the motor 50, and the driving of the motor 50 is stopped.
[0023]
Further, for example, even when the user forcibly moves while the dust receiving unit 31 is stopped with the dust receiving unit 31 facing the insertion port 25, the rotating drum 30 is driven by the driving roller 40 and the supporting roller. 45 and slide on. For this reason, an excessive force is less likely to be applied to the motor 50 via the driving roller 40. Accordingly, it is possible to reduce a failure caused by artificially applying an excessive force to the rotating drum 30.
[0024]
The rotating drum 30 is not rotatably supported by the shaft member, but is rotatably supported by the driving roller 40 and the supporting roller 45 that are in contact with the peripheral surface as described above. Therefore, it is not necessary to remove the shaft member when removing, and the shaft member can be removed very easily, maintenance work such as cleaning is easy, and the cleaning property is excellent.
[0025]
The present invention is not limited to the above embodiment. For example, in the above-described embodiment, the dust feeding mechanism 10 and the dust storage unit 100 are used as a single set and used alone. However, as shown in FIGS. 100 may be arranged adjacent to each other, and the dust feeding mechanism 10 may be attached to each of the two. Thus, even if one of the dust storage units 100 is full of dust and the movement of the rotating drum 30 of the dust feeding mechanism 10 is deteriorated, the dust receiving unit 31 of the rotating drum 30 of the other dust feeding mechanism 10 can be used. You can put garbage from. In this case, it is possible to eliminate the partition wall between the adjacent dust storage units 100 and communicate with the inside. In any case, by providing the plurality of dust mechanisms 10 and the dust storage units 100 in parallel, it is possible to increase the entire dust storage amount and reduce the maintenance frequency. In a narrow space such as a toilet, the depth of the trash can cannot be made too large. In this way, by providing a plurality of garbage mechanisms 10 and garbage storage units 100 in a horizontal direction in a narrow space such as a toilet. , The amount of garbage can be increased.
[0026]
【The invention's effect】
According to the dust feeding mechanism and the dust box of the present invention, the dust drum is provided with a rotating drum that rotates to send dust from the dust inlet to the dust container, and the rotating drum is rotated by a driving roller that contacts the peripheral surface thereof. The configuration is supported as possible. Therefore, in the case where the rotation of the rotating drum is stopped for some reason, even if the user applies a force to rotate the rotating drum, the rotating drum slides on the driving roller and rotates alone. The load of failure can be reduced without imposing an excessive load. Further, since the rotating drum is merely supported on the driving roller, it is extremely easy to remove and maintenance work such as cleaning work can be easily performed.
