Description

The present invention relates to a waste storage device.

For example, Patent Document 1 discloses a waste storage device (denoted as "trash can" in Patent Document 1) suitable for disposing of used sanitary napkins and the like. This waste storage device includes a storage unit and a storage unit cover member that is detachably provided on the storage unit. The accommodating portion cover member is provided with an input port on the upper surface for charging waste such as used sanitary products, and has a lid member for opening and closing the input port. The lid member includes an outer lid portion (corresponding to "lid member 4" in Patent Document 1) and an inner lid portion (corresponding to "sink 5" in Patent Document 1) which are substantially L-shaped when viewed from the side, and is fully closed. When the outer lid is fully open, the outer lid covers the insertion port, and when the inner lid is fully opened, the vicinity of the boundary between the outer lid and the inner lid is pivotally supported by the frame around the insertion port. There is. That is, this lid member is designed so that the inner lid portion covers the input port even at the time of opening when disposing of waste such as used sanitary napkins, and the waste in the storage portion already discarded by the user is discarded. It has the advantage of preventing people from feeling uncomfortable when looking at things (used sanitary products, etc.). The lid member is opened and closed via an arm (“link member 81” in Patent Document 1) that is rotated by a rotary drive unit including an electric motor as a drive source and a gear mechanism that transmits the rotation of the electric motor. .. Further, the accommodating portion cover member is provided with a sensor (infrared sensor or the like) for detecting the approach of a human hand or the like, and the electric motor is driven based on the detection signal of this sensor.

Japanese Patent No. 4005694

In the technique of Patent Document 1, when the sensor detects the approach of a human hand or the like, the signal is transmitted to the electric motor, the driving force of the electric motor is transmitted to the arm (link member) via the gear mechanism, and the arm (link member) is transmitted. The lid member is pressed by the rotation of the link member) to automatically open the lid member. Since the outer lid portion and the inner lid portion of the lid member are formed in a substantially L-shape as described above, when the lid member is fully opened, the outer lid portion is in an upright posture close to 90 degrees in a side view, and the inner lid portion is approximately. The posture is close to horizontal. In this state, the user puts garbage such as used sanitary napkins on the inner lid. After that, when the closing operation is performed, the electric motor is reversely driven. As a result, the arm (link member) returns to its original position, and the lid member closes due to its own weight. During this closing operation, the inner lid rotates downward from a substantially horizontal posture so as to move away from the inlet, and becomes an inverted posture. In the process, dust on the inner lid falls into the accommodating portion. ..

As described above, the lid member is closed by its own weight, but when the outer lid portion vigorously contacts the inlet when closed, an abnormal noise is generated. In order to solve this problem, it is conceivable to separately provide a shock absorber on the shaft portion, but Patent Document 1 does not specify this point, and if a separate shock absorber is provided, the structure becomes complicated. On the other hand, the lubricant applied to the electric motor and gear mechanism becomes highly viscous especially in a low temperature environment such as winter, and the arm (link member) does not return to the original position at the final position during the closing operation, and the lid. There may be a gap between the outer lid of the member and the frame around the slot.

The present invention has been made in view of the above, and it is possible to prevent a situation in which the lid member is vigorously closed and a loud noise is generated when the lid member is closed, or conversely, the lid member is not completely closed. The subject is to provide a waste storage device.

In order to solve the above problems, the waste storage device of the present invention includes a lid member for opening and closing the input port provided in the upper part of the storage portion.
In a waste storage device provided with an opening / closing operation mechanism for opening / closing the lid member.
The lid member includes an outer lid portion and an inner lid portion that are substantially L-shaped in a side view. When the lid member is fully closed, the outer lid portion covers the insertion port, and when the lid member is fully opened, the inner lid portion covers the insertion port. Arranged rotatably to cover the mouth
The opening / closing operation mechanism has an arm that can come into contact with the lid member, a rotation drive unit having a connecting shaft connected to a base end portion of the arm, and a control unit that controls the rotation drive unit. Become
The control unit
At the time of opening operation of the lid member, the rotation drive unit is driven in the normal direction, the lid member is pressed in the opening direction by the arm, and the inner lid portion is operated to a fully open position covering the inlet.
During the closing operation of the lid member, the rotation drive unit is reversely driven with a rotation torque smaller than the rotation torque when the lid member rotates in the closing direction by its own weight, and the lid member is closed while being in contact with the arm. It is operated to slow down the closing speed of the lid member, and
After the lid member is fully closed, the rotation drive unit is set to continue reverse drive and control the arm to be separated from the lid member.

The control unit is configured to control the rotation drive unit to be temporarily driven in the forward rotation and then in the reverse direction again at a predetermined angle before the fully closed position where the outer lid portion covers the insertion port. It is preferable to have.

The outer lid portion and the inner lid member are arranged so that when the inner lid portion covers the insertion port, the outer lid portion is inclined toward the insertion port rather than vertically in a side view. It is preferable that the angle between the lid and the lid is set.

A detection device for detecting the approach of a human hand or the like is arranged above the accommodating portion.
The control unit is preferably configured to drive the rotation drive unit when it receives a detection signal output from the detection device.

It is preferable that the opening / closing operation mechanism is provided with a communication unit capable of communicating with an arbitrary external device, and the operation status of the opening / closing operation mechanism can be communicated.

According to the present invention, when the lid member is closed, the rotation drive unit is reversely driven with a rotation torque smaller than the rotation torque when the lid member rotates in the closing direction by its own weight, and the lid member is brought into contact with the arm. Close operation. Therefore, the closing speed of the lid member can be slowed down without providing a separate cushioning mechanism that is used only at the time of closing, that is, with a simple configuration, and the lid member can be prevented from closing rapidly. As a result, it is possible to prevent the outer lid portion from vigorously contacting the frame portion around the insertion port to generate an abnormal noise when the lid is fully closed.

Further, after the lid member is fully closed, the reverse drive of the rotary drive unit is continued, and the arm is controlled to be separated from the lid member. Therefore, when the lid member is closed, the lid member is not subjected to a force in the opening direction by the arm. As a result, even if the lubricant applied to the electric motor and gear mechanism constituting the rotary drive unit becomes highly viscous in a low temperature environment such as winter, the lid member does not close completely due to that factor. Does not occur.

Further, by configuring the outer lid portion to temporarily drive the rotation drive portion in the forward rotation at a predetermined angle before the fully closed position, the closing operation of the lid member is braked, and the lid member is It is possible to more reliably prevent the generation of abnormal noise when contacting the frame around the slot.

Hereinafter, the present invention will be described in more detail based on the embodiments shown in the drawings. As shown in FIG. 1, the waste storage device 1 of the present embodiment has a storage unit 10 and a storage unit cover member 20 attached to the upper portion thereof. Specifically, the accommodating portion 10 is formed in a substantially square box shape in a plan view having a predetermined height at which the upper portion 11 is opened (see FIGS. 1, 4, and 5). The vertical, horizontal, depth and height dimensions are appropriately set in consideration of the storage capacity of waste (used sanitary products, etc.) and the installation location.

On the other hand, as shown in FIGS. 4 and 5, the accommodating portion cover member 20 is mounted so as to cover the opening of the upper portion 11 of the accommodating portion 10 with the lower portion 21 having an opening and being formed in a substantially square shape in a plan view. .. Specifically, on the inner surfaces of the front portion 27 and the back portion 28 of the accommodating portion cover member 20 near the lower portion, a pair of protrusions 22, 22, 23, and 23 projecting inward are arranged vertically at predetermined intervals. Flange portions 12 and 13 projecting outward at the upper edge of the accommodating portion 10 are formed between the pair of protrusions 22 and 22 on the front portion 27 and between the pair of protrusions 23 and 23 on the back portion 28, respectively. Engagement allows the two to be detachably connected.

As shown in FIG. 2, the accommodating portion cover member 20 is formed with an inlet 24 which is an opening for ejecting dust on the upper surface portion 26 thereof. In the present embodiment, the upper surface portion 26 is formed in an inclined surface shape that is slightly inclined downward from the back surface portion 28 side to the front surface portion 27 side, but this is only an example and is substantially horizontal. It may be formed in. The insertion port 24 has a substantially quadrangular opening formed in a plan view from the vicinity of the boundary between the front portion 27 and the upper surface portion 26 to the front portion 28, and the lid member 30 has the insertion port 24. Is arranged to open or close.

As shown in FIGS. 2, 4 and 5, the lid member 30 includes an outer lid portion 31 and an inner lid portion 32 formed so as to form a substantially L shape in a side view. When the lid member 30 is fully closed, the outer lid portion 31 is in a state of covering the charging port 24, and when the lid member 30 is fully opened, that is, when waste is charged, the inner lid portion 32 is in a state of covering the charging port 24. As described above, the vicinity of the boundary portion 33 between the outer lid portion 31 and the inner lid portion 32 is pivotally supported closer to the back surface portion 28 than the frame portion 261 around the input port 24. More specifically, the lid member 30 has projecting pieces 35 projecting rearward to the left and right near the boundary portion 33 between the outer lid portion 31 and the inner lid portion 32, and projecting outward to each projecting piece 35. Shaft portions 35a are provided respectively, and a pair of bearing pieces 25 provided at predetermined intervals on the left and right so that each shaft portion 35a projects downward on the back surface of the upper surface portion 26 of the accommodating portion cover member 20. It is inserted through the bearing hole 25a so that it is rotatably provided with respect to the accommodating portion cover member 20 around the shaft portion 35a.

The lid member 30 includes an outer lid portion 31 and an inner lid portion 32 as described above, and is formed in a substantially L shape in a side view. However, when the lid member 30 is fully closed, the outer lid portion 31 is formed on the upper surface portion 26. Like the upper surface portion 26, it has an inclined surface shape that becomes lower toward the front side so that it does not fit into the frame portion 261 and creates a gap. When fully opened, the inner lid portion 32 is in a substantially horizontal position covering the insertion port 24. In this embodiment, the angle formed by the outer lid portion 31 and the inner lid portion 32, that is, the extension of the tangent line of the outer surface of the outer wall portion 31 shown in FIG. 4 and the bottom of the inner lid portion 32. The angle θ at which the extension line of the back surface of the wall portion 321 intersects is formed so as to be less than a right angle. As a result, even when the outer lid portion 31 is fully opened, the outer lid portion 31 is not in a substantially vertical posture with respect to the shaft portion 35a, but is in an inclined posture toward the front side, and rotational torque in the closing direction due to its own weight is likely to act.

As a result, when the waste storage device 1 is not in use, the lid member 30 rotates downward with the shaft portion 35a as a fulcrum as shown in FIG. 4, so that the outer lid portion 31 covers the storage portion. The insertion port 24 is closed by abutting on the frame portion 261 around the insertion port 24 of the member 20.

On the other hand, when the waste storage device 1 is used, that is, when the waste is dumped into the waste storage device 1, the lid member 30 is upward with respect to the shaft portion 35a as shown in FIGS. 2 and 5. The outer lid portion 31 is separated from the frame portion 261 of the accommodating portion cover member 20 to open the insertion port 24.

As shown in FIGS. 3, 4 and 5, the inner lid portion 32 includes a bottom wall 321 and side walls 322 and 322 provided on the left and right sides thereof, and the rear end portion is the rear end portion of the outer lid portion 31. It is connected to the part and formed integrally. During the opening operation of the lid member 30, the lid member 30 rotates upward around the shaft portion 35a, so that the inner lid portion 32 moves forward from the inverted state of FIG. 4 to the substantially horizontal state of FIG. The inlet 24 is closed from below. At this time, since the front edge portion 261a of the frame portion 261 of the insertion port 24 is formed so as to project in the back surface portion 28 direction, the tip edge portion 321a of the bottom wall 321 of the inner lid portion 32 hits the lower surface of the front edge portion 261a. In contact, the inlet 24 is closed from below.

As a result, when the outer lid portion 31 of the lid member 30 is fully opened, the inner lid portion 32 covers the input port 24 to become a blindfold, and from the outside, waste such as used sanitary products stored in the storage portion 10 is used. (Garbage) is not visible. Further, the inner lid portion 32 has a structure reinforced by the left and right side walls 322 and 322, and prevents dust placed on the inner lid portion 32 from falling off in the left-right direction.

Further, as shown in FIGS. 2 and 3, a plurality of long row-shaped protrusions 321b are arranged side by side on the inner surface of the inner lid portion 32 in the front-rear direction. As a result, the area of dust that comes into contact with the surfaces of the plurality of protrusions 321b, ..., 321b is reduced, so that even if adhesive dust is placed on the inner lid portion 32, it is difficult for the dust to stick to the surface. Become.

The housing portion 10, the housing portion cover member 20, and the lid member 30 are all made of synthetic resin such as polypropylene rather than metal such as stainless steel in order to reduce the noise generated when the lid member 30 is opened and closed. It is preferable that the product is made of a resin having antibacterial properties.

As shown in FIGS. 4 and 5, the waste storage device 1 is provided with an opening / closing operation mechanism 40 that automatically opens / closes the lid member 30. The opening / closing operation mechanism 40 includes a rotation drive unit 41 and a control unit 42. The rotation drive unit 41 includes an electric motor 411 (stepping motor) and a gear mechanism 412, and the base end portion of the arm 44 is connected to the connecting shaft 412a of the gear mechanism 412. Further, the tip end portion of the arm 44 is arranged so as to be in contact with the back side of the inner lid portion 32 (see FIGS. 4 and 5).

As shown in FIG. 4, when the outer lid portion 31 of the lid member 30 is fully closed, the inner lid portion 32 is in a substantially vertical inverted posture with its tip edge 321a facing downward. When the lid member 30 is operated in the opening direction from this state, the arm 44 is controlled to rotate clockwise in FIG. That is, the arm 44 rotates from the position of the solid line (T1) shown in FIG. 4 and contacts the back side of the inner lid portion 32 at the position of the alternate long and short dash line (T2), and moves in the closing direction due to the weight of the lid member 30. It rotates clockwise from the state shown in FIG. 4 to the state shown in FIG. 5 against the rotational torque, thereby moving the lid member 30 to the opening position.

On the contrary, when the lid member 30 is operated in the closing direction, the arm 44 counterclockwise from the position (T3) shown by the solid line in FIG. 5 to the position (T1) shown by the solid line in FIG. It is controlled to rotate around. Since the inner lid portion 32 of the lid member 30 is in a substantially horizontal posture in the fully open position, the lid member 30 is always subjected to rotational torque due to its own weight in the counterclockwise direction of FIG. 5 with the shaft portion 35a as the center. Therefore, when the arm 44 rotates counterclockwise, the lid member 30 moves in the closing direction while the inner lid portion 32 always contacts the arm 44.

The control unit 42 is composed of a control board incorporating an electronic circuit or the like in which a computer program for adjusting the feed interval of the pulse signal supplied to the electric motor 411 is set. The function of the control unit 42 will be described later. Further, reference numeral 45 is a dry battery, which supplies electricity to the electric motor 411 and the control unit 42 of the rotary drive unit 41.

It is desirable that the opening / closing operation mechanism 40 is provided with a detection device that detects the approach of a hand or the like and outputs the detection signal to the control unit 42 to start driving the electric motor 411. This detection device includes, for example, an infrared sensor 43, and as shown in FIGS. 1, 4 and 5, a window portion 26a is provided on the upper surface portion 26 of the accommodating portion cover member 20 so as to correspond to the window portion 26a. Be placed. As a result, the user can open and close the lid member 30 without directly touching the waste storage device 1.

Next, the function of the control unit 42 for opening and closing the lid member 30 will be described in detail with reference to the flow chart of FIG. First, when the power switch (not shown) of the waste storage device 1 is turned on, electric power is supplied from the dry batteries 45 and 45 (step 10 (S10)). As a result, the detection operation of the infrared sensor 43 is started (step 11 (S11)). At this point, the electric motor 411 is not driven and the opening / closing operation of the lid member 30 does not start.

Next, when the user holds his / her hand near the window portion 26a, it is detected by the infrared sensor 43 (step 12 (S12)). When the infrared sensor 43 detects a hand, the detection signal is sent to the control unit 42, whereby the drive signal is supplied from the control unit 42 to the electric motor 411. That is, a pulse signal is supplied to the electric motor 411 to rotate the electric motor 411, and this rotational torque is transmitted to the connecting shaft 412a via the gear mechanism 412, and the lid member 30 is pressed by the arm 44 connected to the connecting shaft 412a. Forward rotation drive in the opening direction. The arm 44 rotates clockwise in FIGS. 4 and 5 (the direction of displacement from T1 to T3), and when it reaches the position of T2, it comes into contact with the back surface of the inner lid portion 32 of the lid member 30. After that, the inner lid portion 32 is pressed until it reaches the position of T3, and is pushed up against its own weight around the shaft portion 35a (step 13 (S13)).

As a result, since the outer lid portion 31 is integrated with the inner lid portion 32, the outer lid portion 31 has a frame portion 261 whose front end portion 311 forms an inlet 24 for the accommodating portion cover member 20. Separated from the front edge portion 261a, the inlet 24 is opened as shown in FIG. Then, the tip edge 321a of the bottom wall 321 of the inner lid portion 32 comes into contact with the front edge portion 261a of the frame portion 261 of the input port 24 from below, and further rotation is not possible. This position is the fully open position (the arm 44 is the position of T3).

When the lid member 30 reaches the fully open position, the control unit 42 controls to maintain the fully open state for a predetermined set time (step 14 (S14)). That is, when the rotation torque in the opening direction is not applied, the lid member 30 tries to rotate in the closing direction due to its own weight, but the control unit 42 resists the rotation torque in the closing direction due to its own weight. By controlling the pulse signal supplied to the electric motor 411, the lid member 30 is urged in the forward rotation direction with a predetermined rotational torque to maintain the fully open state for a predetermined set time. When the lid member 30 is in the fully open state, the inner lid portion 32 is in a substantially horizontal posture, and during that time, the user puts garbage such as used sanitary products on the inner lid portion 32.

After the above-mentioned predetermined set time, the control unit 42 switches the exciting direction of the pulse signal to the electric motor 411 in the opposite direction to reversely drive the electric motor 411 (step 15 (S15)). As a result, the arm 44 rotates in the closing direction (direction of displacement from T3 to T1). When the arm 44 rotates in the closing direction, the force for holding the lid member 30 in the open state becomes small, so that the lid member 30 tries to rotate in the closing direction due to its own weight following the movement of the arm 44. Therefore, the control unit 42 appropriately adjusts the pulse interval of the pulse signal so that the rotational torque of the electric motor 411 during reverse drive is smaller than the rotational torque when the lid member 30 rotates in the closing direction by its own weight. To control. As a result, the lid member 30 rotates in the closing direction with the back surface of the inner lid portion 32 always in contact with the arm 44, and the closing speed of the lid member 30 is restricted by the arm 44, so that the lid member 30 is closed. Even though it is not provided with a separate shock absorber used only for the time, it will be delayed (step 16 (S16)).

By step 16 described above, the closing speed of the lid member 30 can be slowed down, whereby the contact sound when the outer lid portion 31 of the lid member 30 comes into contact with the frame portion 261 forming the input port 24. Can be reduced. However, in order to further reduce the force when the outer lid portion 31 comes into contact with the frame portion 261, when the lid member 30 is closed, the outer lid portion 31 covers the input port 24 at a predetermined angle before the fully closed position. It is preferable that a control process for applying the brake to the lid member 30 is set. In the present embodiment, the opening angle from the insertion port 24 with the shaft portion 35a as the center is 30 degrees or less from the fully closed position (T2 position in the arm 44) where the outer lid portion 31 covers the insertion port 24. When any of the angles, preferably any angle of 20 degrees or less, more preferably any angle of 10 degrees or less) is reached, the control unit 42 excites the pulse signal to the electric motor 411. Is switched to the forward rotation direction, and the electric motor 411 is controlled to be temporarily driven in the forward rotation (step 17 (S17)).

As a result, the arm 44 temporarily generates rotational torque in the opening direction at a position on the predetermined angle T3 side from the T2 position, so that the lid member 30 in which the inner lid portion 32 is in contact with the arm 44 is closed. The brake is applied. However, the control unit 42 makes the rotation torque generated at this time that the arm 44 rotates in the opening direction smaller than the rotation torque in the closing direction due to the weight of the lid member 30, that is, the arm 44. Is controlled so that the rotation torque is such that the lid member 30 cannot be rotated in the opening direction again. By this step 17, the closing operation of the lid member 30 is stopped, or the closing speed becomes extremely slow even if the closing operation is not reached.

In step 17, the brake is applied immediately before the fully closed position, but if the control is such that the lid member 30 does not stop completely and the closing speed becomes extremely slow, that state is maintained, that is, the electric motor 411 is positive. It is also possible to bring the lid member 30 to the fully closed position while being driven to roll. However, the position where the brake is applied is immediately before the fully closed position as described above, and the distance between the outer lid portion 31 of the lid member 30 and the frame portion 261 is also very short. Therefore, from that position, the excitation direction of the pulse signal to the electric motor 411 is switched in the opposite direction, and the electric motor 411 is driven in the reverse direction, and the arm 44 is closed while the inner lid portion 32 is in contact with the arm 44. This is preferred for a faster closing operation (step 18 (S18)). As a result, the arm 44 rotates to the position (T2) of the alternate long and short dash line in FIG. 4 while being in contact with the inner lid portion 32.

Therefore, in step 17, the lid member 30 is braked before the fully closed position to slow down the closing speed, and then in step 18, the lid member 30 is quietly and slowly closed while receiving the resistance of the electric motor 411. As a result, the lid member 30 quietly does not generate a loud contact noise at the final position of the closing operation even in a high temperature environment such as summer when the resistance of the lubricant used for the electric motor 411 and the gear mechanism 412 becomes small. It will close slowly.

In the present embodiment, the control unit 42 further supplies the pulse signal to the electric motor 411 so that the exciting direction of the pulse signal to the electric motor 411 continues in the opposite direction even after reaching the fully closed position of the lid member 30, that is, The reverse drive of the electric motor 411 is continuously controlled so that the arm 44 is separated from the inner lid portion 32 (step 19 (S19)).

As a result, the lid member 30 rotates from the position of the alternate long and short dash line (T2) in FIG. 4 to the position of the solid line (T1), and the arm 44 is separated from the bottom wall 321 of the inner lid portion 32. As a result, a gap is formed between the electric motor 411 and the gear mechanism 412, and the force thereof is not received. That is, when the lid member 30 is fully closed, if the arm 44 rotates only to the position (T2) of the alternate long and short dash line in FIG. 4, the arm 44 is always in contact with the inner lid portion 32 even when the lid member 30 is fully closed. Will be there. Therefore, in a low temperature environment such as winter when the viscosity of the lubricant used for the electric motor 411 and the gear mechanism 412 becomes high, the rotation angle of the arm 44 at the final position of the closing operation becomes insufficient due to the resistance. There is a possibility that the outer lid portion 31 does not completely abut on the frame portion 261 and remains slightly open. However, by providing the control step of step 19 as in the present embodiment and setting the standby position of the arm 44 when fully closed to the position (T1) separated from the inner lid portion 32 as described above, the lubricant can be used. Even in a low temperature environment where the viscosity is high, the outer lid portion 31 can be reliably brought into contact with the frame portion 261 and the input port 24 can be reliably closed.

It is preferable that the opening / closing operation mechanism 40 of the waste storage device 1 according to the present embodiment is provided with a communication unit (not shown) capable of communicating with an arbitrary external device. Thereby, the operation status of the opening / closing operation mechanism 40 can be communicated. For example, the number of opening / closing operations of the waste storage device 1, the driving voltage of the electric motor 411, or the occurrence of an abnormal situation when a foreign matter is caught in the lid member 30 and the electric motor 411 is overloaded. Extract the operation information. These operation information can be transmitted from the communication unit to a communication terminal such as an installer of the waste storage device 1 or a rental company renting the waste storage device 1. Based on this transmitted operation information, the business operator can promptly respond to any abnormal information, and for example, the battery life and replacement time, and the waste storage unit 10 of the waste storage device 1 is full of waste. It is also possible to predict when it will be (that is, maintenance time).

Further, the accommodating unit 10 can be provided with a foreign matter detecting device that detects a foreign matter different from the preset waste object. As the foreign matter detection device, a detector that reacts with metal or other sensors is provided. In this case, the control unit 42 is provided with a function of transmitting the detection signal data output from the foreign matter detection device as one of the operation information from the communication unit. As a result, the foreign matter detecting device detects that foreign matter such as metal or explosive is thrown into the accommodating portion 10, transmits the detection signal from the communication unit to the above communication terminal, and promptly throws in the foreign matter. I can tell you.
