The sewage throwing operation of the sewage treatment apparatus according to this embodiment will be described with reference to FIGS. 1, 2A, 2B, 3 and 5. When a sanitary article or other dirt is brought near the object detection sensor 3 incorporated in the upper surface of the main body 1 of the present device, the object detection sensor 3 such as a photoelectric sensor, an ultrasonic sensor, or a pyroelectric sensor is Detect this dirt or hand. At this point, the charging port 27 is closed. When the control means 9 receives this detection signal, the control means 9 rotates (normally rotates) the L-shaped lid motor 10 installed beside the L-shaped lid 2. The rotation of the L-shaped lid motor 10 rotates the pinion gear 17, the pinion gear 17 rotates the gear A18 connected thereto, and the gear A18 rotates the gear B28 connected thereto. When the gear B28 rotates, the column 30 fixed to the gear B28 swings around the rotation shaft 29, and the swing of the column 30 starts the opening movement of the L-shaped lid 2. When the gear B28 further rotates in the normal direction, the support column 30 also rotates in the same direction, and the insertion port 27 is further opened. When the L-shaped lid 2 is completely opened, the L-shaped lid motor 10 is stopped. At this time, the first end 201 of the L-shaped lid 2 abuts against the inner surface 22 of the main body, and the concave surface of the L-shape forms an upward waste container under the inlet 27. The filth receiver can temporarily receive filth introduced from the opening 27. Next, the control means 9 detects that a certain period of time has passed since the object detection sensor 3 detected the dirt or hand by means of a timer 34 timeout, and the L-shaped lid motor 10 is rotated in the opposite direction again (reverse rotation). ) Let me. The rotation of the L-shaped lid motor 10 causes the pinion gear 17 to rotate.
Are rotated in the opposite direction, the pinion gear 17 rotates the gear A18 connected thereto, and the gear A18 rotates the gear B28 connected thereto. When the gear B28 rotates, the column 30 fixed to the gear B28 is swung in the opposite direction around the rotation shaft 29, and the swing of the column 30 causes the L-shaped lid 2 to start closing the insertion port 27. At this time, the first end portion 201 of the L-shaped lid 2 is separated from the inner surface 22 of the main body, so that the waste is put into the recovery vinyl bag 13 by spontaneous fall. The insertion port 27 is completely closed when the second end 202 of the L-shaped lid 2 hits the inner surface 22 of the main body.

In this state, the concave side surface of the L-shaped lid 2 is not visible, and one side of the L-shaped convex side surface covers the charging port 27 from below and closes the charging port 27. There is. The surface shape of the surface forming the L-shaped lid 2 may be a surface cut out from a rotating body such as a cylinder or a spindle. In this embodiment, as seen from the front, as shown in FIGS. 1 and 2 (c). Cut out into an elliptical shape. In addition to this, the shape may be circular, square, or the like. The recovery door switch 16 is for confirming whether the recovery door 6 is opened or closed. When the recovery door 6 is closed, the recovery door switch insulator 15 attached to the recovery door 6 side is attached to the main body. The contact of the recovery door switch 16 is blocked, but when the recovery door 6 is opened, the recovery door switch insulator 15 is pulled out, and the contact of the recovery door switch 16 is connected. This allows the control means 9 to confirm that the recovery door 6 has been opened.

Next, the mechanism of the L-shaped lid 2 which can open and close the inlet 27 without leaking odor will be described with reference to FIGS. 3 (a) and 3 (b). The L-shaped lid 2 has a packing 21 at a first end 201 and a packing 2 at a second end 202.
0 is provided. When the L-shaped lid 2 is completely closed as shown in FIG. 3A, the packing 20 at the second end 202 is in the most contracted state. L-shaped lid 2
The packing 20 begins to expand when the sack starts to open. When the L-shaped lid 2 is further opened, the packing 21 of the first end 201 is
Starts to shrink against the inner surface 22 of the body, and then the packing 20 at the second end 202 is fully extended away from the inner surface 22 of the body. When the insertion port 27 is completely open as shown in FIG. 3B, the packing 2 of the first end 201 is
1 is the most contracted state. When the L-shaped lid 2 is closed, it follows the reverse of opening. Rocked second
The packing 20 of the end portion 202 of the first contact the inner surface 22 of the main body. After that, the packing of the first end portion 201 is fully extended and begins to separate from the inner surface 22 of the main body. With the above mechanism,
The inside cannot be seen when the L-shaped lid 2 is opened and closed, and the odor does not leak. Both ends of the L-shaped lid 2 in the rotation axis direction are covered with side wall surfaces (not shown) extending from the main body 1 and are sealed. The input detection sensor 11 is provided on the side wall surface. The material of the packing 20 is preferably natural rubber, synthetic rubber or the like, which can be easily molded and can withstand repeated expansion and contraction. Further, it is effective to make the shape into a bellows shape in order to secure elasticity.

The mechanism of the slidable closed slide lids 23 and 24 shown in FIGS. 4A and 4B is basically the same as the packings 20 and 21. When the L-shaped lid 2 is completely closed as shown in FIG. 4 (a), the sealing slide lid 23 at the second end 202 completely enters the groove of the L-shaped lid 2 and the sealing slide lid 23 is closed. The spring 25 for pushing out is in the most compressed state. When the L-shaped lid 2 starts to open, the spring 25 begins to expand and the closed slide lid 2

When is pushed out, the sealing slide lid 23 stops stretching and the sealing slide lid 23 is separated from the inner surface 22 of the main body as it is. Immediately before the sealing slide lid 23 separates, the sealing slide lid 24 of the first end 201 abuts the inner surface 22 of the main body, and the spring 26 begins to contract. As shown in FIG. 4B, when the insertion port 27 is completely opened, the closed slide lid 24 completely enters the groove of the L-shaped lid 2, and the spring 26 is in the most compressed state. . When the L-shaped lid 2 is closed it is the opposite of when it is opened and before the sealing slide lid 24 of the first end 201 is separated from the inner surface 22 of the body, the second end 20 is closed.
The second closed slide lid 23 abuts the inner surface 22 of the main body.
With the above mechanism, the inside cannot be seen when opening and closing the L-shaped lid,
A structure that does not leak odor is realized.

Next, the flow of operation will be described with reference to FIGS. 6 and 7. FIG. 6 is an operation flow chart when the filth is thrown in. As shown in FIG. 6, when the power is turned on (START), the standby state is entered. When a hand or filth is brought close to the main body 1 in the standby state, the object detection sensor 3 detects the hand or filth. When the control means 9 receives the detection signal from the object detection sensor 3, the control means 9 releases the standby state and starts the operation. The control means 9 first rotates the deodorizing fan 5. Next, the battery voltage is checked by the battery voltage detection means 36, and if the voltage level is below the set value, the battery replacement display L
Turn on ED32. Further, if the number of filth thrown is already equal to or more than the set value, the full display LED 31 is turned on. Then, the L-shaped lid motor 10 is driven to open the L-shaped lid 2. From this point, the timer 34 waits for a predetermined time to elapse. When the timer 34 has timed out and filth is received by the filth receiver, the input detection sensor 11 including a photoelectric sensor detects this, and the control means 9 receives this signal, whereby the control means 9 counts the number of inputs. The counter 35 is incremented. At this time, if the number of thrown batteries reaches the set value, the control means 9 causes the full display LED 3
1 is turned on. After the above steps, the L-shaped lid motor 10 is driven in the reverse direction to close the L-shaped lid 2. Then, the deodorizing fan 5 is stopped, and finally, the object detection sensor 3
If the object is not detected, it returns to the standby state again, and if it is detected, the operation is repeated from the place where the deodorizing fan 5 is rotated.

Next, the flow of the waste collection operation shown in FIG. 7 will be described. First, turn on the power (START)
Then, when the maintenance switch 14 of the main body in the standby state is pressed, all outputs are turned off. The control means 9 confirms the voltage level by the battery voltage detection means 36, and if the voltage level is below the set value, turns on the battery replacement display LED 32. Then, if the number of inputs is equal to or larger than the set value, the full-display LED 31 is turned on. Next, when the recovery door 6 is opened, the recovery door switch 16 detects that the recovery door 6 has been opened, and the counter 35 for the number of input sheets is set to zero. Finally maintenance switch 1
When it is confirmed that 4 has been pressed, it returns to the standby state. In this way, maintenance can be performed very easily.
