Description

  The present invention relates to a waste container.

  For example, Patent Document 1 discloses a waste container device (indicated as “trash box” in Patent Document 1) suitable for discarding used sanitary products and the like. This waste container includes a container and a container cover member that is detachably provided on the container. The accommodating portion cover member is provided with an inlet on the upper surface for introducing waste such as used sanitary goods, and has a lid member for opening and closing the inlet. The lid member is provided with an outer lid portion (corresponding to “lid member 4” in Patent Document 1) and an inner lid portion (corresponding to “Tray 5” in Patent Document 1) that are substantially L-shaped in a side view, and is fully closed The outer lid part covers the inlet, and when fully opened, the inner lid part covers the inlet, and the boundary between the outer lid and inner lid is pivotally supported by the frame around the inlet. Yes. In other words, this lid member is configured so that the inner lid covers the insertion port even when opened when discarding wastes such as used sanitary products, and the user discards the waste in the storage unit that has already been discarded. There is an advantage that it is possible to prevent an object (such as a used sanitary product) from being uncomfortable. The lid member is opened and closed via an arm (“link member 81” in Patent Document 1) that rotates by a rotation drive unit that includes an electric motor as a drive source and a gear mechanism that transmits the rotation of the electric motor. . In addition, the housing cover member is provided with a sensor (infrared sensor or the like) that detects the approach of a human hand or the like, and the electric motor is driven based on a detection signal of the sensor.

Japanese Patent No. 40056494

  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, and the driving force of the electric motor is transmitted to the arm (link member) via the gear mechanism. The lid member is pressed by the rotation of the link member) to automatically open. As described above, since the outer lid portion and the inner lid portion are formed in a substantially L shape as described above, when the lid member is fully opened, the outer lid portion is in a standing posture close to 90 degrees in side view, and the inner lid portion is substantially The posture is almost horizontal. In this state, the user places garbage such as used sanitary goods on the inner lid. Thereafter, when the closing operation is performed, the electric motor is reversely driven. As a result, the arm (link member) returns to the original position, and the lid member is closed by its own weight. During this closing operation, the inner lid portion rotates downward from a substantially horizontal posture so as to move away from the inlet, and in the process, dust on the inner lid portion falls into the accommodating portion. .

  As described above, the lid member closes due to its own weight, but when the outer lid portion vigorously abuts the insertion port when closed, an abnormal noise is generated. In order to solve this problem, it is conceivable to separately provide a shock absorber in the shaft portion. However, 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 can prevent a situation in which the lid member closes vigorously when the lid member is closed and a loud sound is generated or the lid member is not completely closed. It is an object to provide a waste container.

In order to solve the above-described problem, the waste container of the present invention includes a lid member that opens and closes a charging port provided in an upper part of the container,
In the waste container including the opening / closing 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, and the outer lid portion covers the inlet when fully closed, and the inner lid portion is the inlet when fully opened. It is rotatably arranged so as to cover the mouth,
The opening / closing mechanism includes an arm that can contact the lid member, a rotation driving unit that includes a connecting shaft that is connected to a base end portion of the arm, and a control unit that controls the rotation driving unit. Become
The control unit is
During the opening operation of the lid member, the rotation drive unit is driven to rotate forward, the lid member is pressed in the opening direction by the arm, and the inner lid unit is operated to a fully opened position covering the insertion port,
During the closing operation of the lid member, the rotation drive unit is driven in reverse rotation with a rotational torque smaller than the rotational torque when the lid member rotates in its closing direction by its own weight, and the lid member is closed while contacting the arm. Actuate to slow down the closure speed of the lid member; and
After the lid member is fully closed, the reverse drive of the rotation drive unit is continued and the arm is separated from the lid member.

  The control unit is configured to control so that the rotation driving unit is temporarily forward-rotated and then reverse-rotated again after a predetermined angle before the fully-closed position where the outer lid part covers the insertion port. Preferably there is.

  The lid member and the inner lid portion are arranged so that the outer lid portion is inclined closer to the inlet port than in the vertical direction in a side view when the inner lid portion is fully opened to cover the inlet port. It is preferable that the angle formed by the lid portion is set.

A detection device for detecting the approach of a human hand or the like is disposed on the upper portion of the housing portion,
Preferably, the control unit is configured to drive the rotation driving unit when receiving 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, during the closing operation of the lid member, while the lid member is driven in reverse by a rotational torque smaller than the rotational torque when the lid member rotates in the closing direction by its own weight, the lid member is brought into contact with the arm. Close operation. Therefore, the closing speed of the lid member can be delayed without providing a separate buffer 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, when the cover is fully closed, it is possible to prevent the outer lid portion from vigorously contacting the frame portion around the inlet and generating abnormal noise.

  Further, after the lid member is fully closed, the rotation drive unit is controlled to continue the reverse rotation so that the arm is separated from the lid member. For this reason, at the time of closing, the lid member does not receive 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 rotation drive unit becomes highly viscous in a low-temperature environment such as winter, the lid member does not completely close due to that. Does not occur.

  In addition, when the outer lid part is configured to temporarily rotate the rotation drive part forward by a predetermined angle before the fully closed position, the closing operation of the lid member is braked. It is possible to more reliably prevent the generation of abnormal noise when contacting the frame portion around the insertion port.

FIG. 6 is a flowchart showing the opening / closing operation of the lid member.

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

  On the other hand, as shown in FIGS. 4 and 5, the housing portion cover member 20 is attached so that the lower portion 21 is open, is formed in a substantially square shape in plan view, and covers the opening of the upper portion 11 of the housing portion 10. . Specifically, a pair of protrusions 22, 22 and 23, 23 projecting inwardly on the inner surfaces of the housing portion cover member 20 near the lower portions of the front portion 27 and the rear portion 28, respectively, at a predetermined interval in the vertical direction. Flange portions 12 and 13 are formed between the pair of projections 22 and 22 of the front portion 27 and between the pair of projections 23 and 23 of the back surface portion 28 and project outward at the upper edge portion of the housing portion 10. Engage, thereby both being detachably connected.

  As shown in FIG. 2, the container cover member 20 has a top surface 26 formed with a loading port 24 that is an opening for loading garbage. In the present embodiment, the upper surface portion 26 is formed in an inclined surface shape that slightly inclines downward from the back surface portion 28 side toward the front surface portion 27 side. However, this is merely an example, and is substantially horizontal. It may be formed. The insertion port 24 is formed in an approximately rectangular shape in plan view from the vicinity of the boundary between the front portion 27 and the upper surface portion 26 to before reaching the back surface portion 28, and the lid member 30 is formed of the insertion port 24. 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 that are formed in 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 inlet 24, and when fully opened, that is, when the waste is introduced, the inner lid portion 32 is in a state of covering the inlet 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 insertion port 24. More specifically, the lid member 30 has projecting pieces 35 that project rearward to the left and right in the vicinity of the boundary portion 33 between the outer lid section 31 and the inner lid section 32, and project outward from each projecting piece 35. Each of the shaft portions 35a is provided, and each of the shaft portions 35a has a pair of bearing pieces 25 provided at predetermined intervals on the left and right sides so as to protrude downward on the back surface of the upper surface portion 26 of the housing portion cover member 20. It is inserted in the bearing hole 25a, and is thereby provided so as to be rotatable with respect to the accommodating portion cover member 20 around the shaft portion 35a.

  The lid member 30 includes the outer lid portion 31 and the inner lid portion 32 as described above, and is formed in an approximately 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. As with 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 when fully opened, the inner lid portion 32 has a substantially horizontal position that covers the inlet 24. Therefore, in this embodiment, the angle formed by the outer lid portion 31 and the inner lid portion 32, that is, the extension line of the tangent to 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 extended line on the back surface of the wall 321 intersects is formed to be less than a right angle. As a result, even when fully opened, the outer lid portion 31 does not take a substantially vertical posture with the shaft portion 35a as the center, but assumes a posture inclined to 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 container 1 is not used, the lid member 30 rotates downward with the shaft portion 35a as a fulcrum as shown in FIG. The input port 24 is closed by contacting the frame portion 261 around the input port 24 of the member 20.

  On the other hand, when the waste container 1 is used, that is, when the waste is discarded in the waste container 1, the lid member 30 moves upward with the shaft portion 35 a as the center as shown in FIGS. 2 and 5. , The outer lid portion 31 is separated from the frame portion 261 of the housing 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 of which the rear end portion is the rear end of the outer lid portion 31. It is connected to the part and formed integrally. When the lid member 30 is opened, the lid member 30 rotates upward about 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. And the closing port 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 to protrude in the direction of the back surface portion 28, the leading edge 321a of the bottom wall 321 of the inner lid portion 32 contacts the lower surface of the front edge portion 261a. Then, 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 is blindfolded by covering the insertion port 24, and wastes such as used sanitary goods housed in the housing portion 10 from the outside. (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 the 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 row-like protrusions 321 b extending in the front-rear direction are arranged side by side on the inner surface of the inner lid portion 32. Thereby, since the area of the dust which contacts the surface of the plurality of protrusions 321b,..., 321b is reduced, for example, even if dust having adhesiveness is placed on the inner lid portion 32, it is difficult to stick to the surface. Become.

  In addition, in order to reduce the sound which generate | occur | produces at the time of opening and closing of the cover member 30, the above-mentioned accommodating part 10, the accommodating part cover member 20, and the cover member 30 are all made of synthetic resin such as polypropylene rather than metal such as stainless steel. It is preferable that the resin is made of a resin imparted with antibacterial properties.

  As shown in FIGS. 4 and 5, the waste container 1 is provided with an opening / closing operation mechanism 40 that automatically opens and closes the lid member 30. The opening / closing operation mechanism 40 includes a rotation driving 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 coupled to the coupling shaft 412 a of the gear mechanism 412. Further, the distal end portion of the arm 44 is disposed 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 the leading edge 321a facing downward. When the lid member 30 is moved from this state in the opening direction, the arm 44 is controlled to rotate clockwise in FIG. That is, the arm 44 rotates from the solid line position (T1) shown in FIG. 4 and contacts the back side of the inner lid part 32 at the two-dot chain line position (T2). 4 rotates from the state of FIG. 4 to the state of FIG. 5 against the rotational torque, thereby moving the lid member 30 to the open position.

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

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

  The opening / closing mechanism 40 preferably includes a detection device that detects the approach of a hand or the like and outputs a detection signal to the control unit 42 to start driving the electric motor 411. The 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, and the window portion 26a corresponds to the window portion 26a. Be placed. Accordingly, the user can open and close the lid member 30 without directly touching the waste container 1.

  Next, the function of the controller 42 that opens and closes the lid member 30 will be described in detail with reference to the flowchart of FIG. First, when a power switch (not shown) of the waste container 1 is turned on, power is supplied from the dry batteries 45 and 45 (step 10 (S10)). Thereby, the detection operation of the infrared sensor 43 is started (step 11 (S11)). At this time, the electric motor 411 is not driven, and the opening / closing operation of the lid member 30 is not started.

  Next, when the user holds his hand near the window portion 26a, the infrared sensor 43 detects it (step 12 (S12)). When the infrared sensor 43 detects a hand, the detection signal is sent to the control unit 42, whereby a 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 moved by the arm 44 connected to the connecting shaft 412a. Drive forward in the opening direction. 4 and 5, the arm 44 rotates clockwise (in the direction of displacement from T1 to T3). When the arm 44 reaches the position of T2, the arm 44 comes into contact with the back surface of the inner lid portion 32 of the lid member 30. Thereafter, the inner lid portion 32 is pressed until reaching 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 integral with the inner lid portion 32, the outer lid portion 31 has a front end portion 311 of the frame portion 261 that forms the insertion port 24 of the housing portion cover member 20. The charging port 24 is opened away from the front edge 261a as shown in FIG. And the front-end edge 321a of the bottom wall 321 of the inner cover part 32 contact | abuts from the downward direction to the front edge part 261a of the frame part 261 of the insertion port 24, and it becomes impossible to rotate any more. This position is the fully open position (the arm 44 is at the position 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 rotational 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 rotational 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 normal rotation direction with a predetermined rotational torque, and kept fully open 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 places garbage such as used sanitary goods on the inner lid portion 32.

  After the predetermined set time, the control unit 42 switches the excitation direction of the pulse signal to the electric motor 411 to the reverse direction to drive the electric motor 411 in reverse (step 15 (S15)). Thereby, the arm 44 rotates in the closing direction (direction displaced from T3 toward T1). When the arm 44 rotates in the closing direction, the force for holding the lid member 30 in the open state decreases, so that the lid member 30 tries to rotate in the closing direction by 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 at the time of reverse driving of the electric motor 411 is smaller than the rotational torque when the lid member 30 rotates in its closing direction under its own weight. And control. Accordingly, 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 regulated by the arm 44. Although there is no separate buffer mechanism used only for the time, it is delayed (step 16 (S16)).

  By the above step 16, the closing speed of the lid member 30 can be delayed, and thereby the contact sound when the outer lid portion 31 of the lid member 30 comes into contact with the frame portion 261 forming the insertion 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, during the closing operation of the lid member 30, a predetermined angle before the fully closed position where the outer lid portion 31 covers the insertion port 24, It is preferable that a control process for applying a brake to the lid member 30 is set. In the present embodiment, a predetermined angle before the fully closed position (T2 position in the arm 44) where the outer lid portion 31 covers the inlet 24 (for example, the opening angle from the inlet 24 around the shaft portion 35a is 30 degrees or less. ), Preferably any angle of 20 degrees or less, more preferably any angle of 10 degrees or less), the control unit 42 performs the excitation direction of the pulse signal to the electric motor 411. Is switched to the normal rotation direction, and the electric motor 411 is controlled to temporarily rotate forward (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 is configured so that the rotation torque that the arm 44 generated at this time rotates in the opening direction is 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 as to obtain a rotational torque that cannot rotate the lid member 30 in the opening direction again. By this step 17, even if the closing operation of the lid member 30 is stopped or not stopped, the closing speed becomes extremely slow.

  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, the state is maintained, that is, the electric motor 411 is corrected. 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 to the reverse direction again, and the electric motor 411 is driven in reverse rotation, and the arm 44 is closed while contacting the inner lid portion 32. Is preferable for a quicker closing operation (step 18 (S18)). Thereby, the arm 44 rotates to the position (T2) of the two-dot chain line in FIG.

  Therefore, the lid member 30 is braked before the fully closed position in step 17 and the closing speed is slowed down in step 17, and thereafter, in step 18, the lid member 30 is gently and slowly closed while receiving the resistance of the electric motor 411. Thereby, even in a high temperature environment such as summer when the resistance of the lubricant used in the electric motor 411 and the gear mechanism 412 is reduced, the lid member 30 is quietly generated without generating a large contact sound at the final position of the closing operation. It will close slowly.

  In the present embodiment, the control unit 42 further supplies a pulse signal so as to continue the excitation direction of the pulse signal to the electric motor 411 in the reverse direction even after reaching the fully closed position of the lid member 30. Control is performed so that the arm 44 is moved away from the inner lid portion 32 by continuing the reverse rotation of the electric motor 411 (step 19 (S19)).

  As a result, the lid member 30 rotates from the position of the two-dot chain 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, there is a gap between the electric motor 411 and the gear mechanism 412, and the force is not received. That is, when the arm 44 rotates only to the position of the two-dot chain line (T2) in FIG. 4 when the lid member 30 is fully closed, the arm 44 is always in contact with the inner lid portion 32 even when fully closed. Will be. Therefore, when the rotation angle of the arm 44 at the final position of the closing operation becomes insufficient due to the resistance in a low temperature environment such as winter when the viscosity of the lubricant used in the electric motor 411 and the gear mechanism 412 becomes high. There is a possibility that the outer lid part 31 does not completely abut against the frame part 261 and remains slightly open. However, the control process of step 19 is provided as in this embodiment, and the standby position of the arm 44 when fully closed is set to the position (T1) separated from the inner lid portion 32 as described above, so that the lubricant Even in a low temperature environment where the viscosity becomes high, the outer lid portion 31 can be reliably brought into contact with the frame portion 261 and the charging port 24 can be reliably closed.

  In addition, it is preferable to provide the communication part (not shown) which can communicate with the external arbitrary apparatuses in the opening / closing operation mechanism 40 of the waste container 1 which concerns on this embodiment. Thereby, the operation status of the opening / closing mechanism 40 can be communicated. For example, the number of opening / closing operations of the waste container 1, the driving voltage of the electric motor 411, or the occurrence of an abnormal situation such as when the electric motor 411 is overloaded due to foreign matter caught in the lid member 30, etc. Extract operation information. The operation information can be transmitted from the communication unit to a communication terminal such as an installer of the waste container 1 or a rental company that rents the waste container 1. Based on the transmitted operation information, the business operator can respond quickly if it is abnormal information. For example, the battery life or replacement time, and the waste storage device 1 is full of waste. It is possible to predict when it will become (that is, maintenance time).

  In addition, the storage unit 10 can be provided with a foreign object detection device that detects a foreign object different from a preset disposal 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 object detection device as one piece of operation information from the communication unit. As a result, the foreign object detection device detects that a foreign object such as a metal or explosive material has been introduced into the storage unit 10, and transmits the detection signal from the communication unit to the communication terminal to promptly insert the foreign object. I can inform you.
