Description

  The present invention relates to a trash can provided with a lid that automatically opens and closes.

2. Description of the Related Art Trash bins that can be opened and closed by stepping on a pedal with feet are well known. In addition, the trash box shown in Patent Document 1 allows the hook-shaped shutter pig to be automatically closed after the garbage is thrown away by the tension of the rubber belt, and immediately after the shutter pig is closed, spraying for aroma / deodorant or insect repellent. It is intended to be done.
Japanese Patent Laid-Open No. 11-059807

  By the way, the trash can with a foot pedal as described above is difficult to separate the trash can main body, the pedal part, and the cover plate. There is a problem of getting in the way. In addition, since the trash box described in Patent Document 1 must be operated manually when opening the shutter cover, it is easy to get dirty by touching the lever with dirty hands, and holding large trash with both hands. There is a problem that it is difficult to operate.

  Therefore, the present invention is intended to provide a trash can that can be used in a sanitary manner while the lid automatically opens and closes without requiring an opening and closing operation, thereby significantly improving convenience.

  For this purpose, the trash can according to claim 1 forms a frame-like body that is detachably attached to the upper end opening edge of the trash can body, hinges a lid that is opened and closed by a motor inside the frame-like body, An infrared sensor is provided on the front surface of the frame-like body, and the movement of the object is sensed by the sensor to activate the motor to automatically open the lid, and the movement of the object is not sensed by the sensor. In this case, an opening / closing control board for automatically closing the lid is provided in the frame-like body.

  According to a second aspect of the present invention, in the above trash box, the motor and the lid are connected via a reduction gear group, and a spring for biasing the lid in the opening direction is provided.

  According to a third aspect of the present invention, in the trash box, a germicidal lamp is provided on the inner surface of the lid.

  In the trash box according to the first aspect, the lid automatically opens and closes without requiring an opening and closing operation, which is highly convenient and can be used hygienically.

  According to the second aspect of the present invention, the load accompanying opening and closing of the lid is reduced, so that the lid can be smoothly opened and closed even when a low-horsepower DC motor is used as a drive source.

  In the invention described in claim 3, as soon as the trash in the trash box is thrown away, it is sterilized and can always be kept hygienic.

  Next, examples of the present invention will be described. FIG. 1 is an external perspective view of the trash box, FIG. 2 is a central vertical cross-sectional view thereof, and FIG. 3 is a vertical cross-sectional view in which the vertical position is shifted. Reference numeral 1 denotes a plastic trash box body. Reference numeral 2 denotes a plastic frame body that is detachably attached to the upper end opening edge of the trash box body. The frame body includes a main body portion 2a and a bottom surface portion 2b. These are formed in a hollow shape by being fixed with a combination screw. 3 is a plastic lid molded to a size that matches the inside of the frame-like body, and this lid is formed on the upper surface of the front edge of the rear side of the frame-like body 2 as shown in FIG. The support shaft 4a is inserted into the plurality of bearing portions 4 so as to be hinged so as to be opened and closed. Reference numeral 5 denotes a winding spring provided on the bearing portion 4, and the winding spring urges the lid 3 upward to bear the weight of the lid 3 so that the lid 3 can be opened and closed with a slight force. Like that. Reference numeral 6 denotes a fan-shaped gear integrally formed on the rear edge of the lid 3 so as to protrude.

  Further, 7 is a battery box formed on the bottom surface 2b corresponding to the bottom of the rear side of the frame-like body 2, 7a is an open / close lid formed on the bottom surface 2b for battery replacement, and 8 is a frame-like body 2. A power switch provided on the rear side, 9 is a gear box provided in the frame-like body 2 and incorporating a reduction gear group, and 10 is a direct current motor fixed to the side of the gear box. It is connected to the gear 11 exposed on the upper surface of the gear box through the reduction gear group. The gear 11 is engaged with the gear 6. For this reason, the rotating shaft of the motor 10 operates forward and backward, the rotational speed thereof is several tenths, the gear 11 rotates forward and backward, and the gear 3 is driven strongly to open and close the lid 3. It is like that.

  Further, 12 is an infrared sensor provided at the front of the frame-like body 2, 13 is a pilot lamp made of LEDs, 14 is a push button type opening operation switch, and 15 is a closing operation switch. Reference numeral 16 denotes an opening / closing control board provided in the frame-like body 2. As shown in the block diagram of FIG. 4, the opening / closing control board 16 includes these electronic components, the battery box 7, the power switch 8, The motor 10 and the like are wired.

  Reference numeral 17 denotes an ultraviolet germicidal lamp provided on the inner surface of the lid 3. The germicidal lamp 17 is also wired to the open / close control board 16 and its lighting is controlled.

  The infrared sensor 12 senses the movement of an object such as a human body or dust that moves immediately before the infrared sensor 12 and transmits the detection signal to the open / close control board 16. When the open / close control board 16 receives the detection signal, the motor 10 is turned on. The lid 3 is automatically rotated through the reduction gear group as shown in FIG. If the infrared sensor 12 does not sense the movement of an object such as a human body or dust for a certain period of time, the open / close control board 16 rotates the motor 10 reversely to automatically close the lid 3 as shown in FIG.

  For this reason, even if it has trash with both hands, it opens automatically without touching the lid 3, and it is very convenient for putting the trash into the trash box body 1. Since it is closed, it does not stain your hands, and the odor does not spread or pests do not enter, so you can always maintain hygiene.

  Further, the germicidal lamp 17 can be used more hygienically by setting so that the lighting is controlled by the open / close control board 16 and the lid 3 is lit for several minutes after being closed. In addition, it is possible to prevent the dry battery from being consumed by lighting the germicidal lamp 17 only for a few minutes after the lid 3 is closed.

  Further, the motor 10 and the lid 3 are connected via a reduction gear group, and the spring 5 that biases the lid 3 in the opening direction is provided, so that the weight is offset and the dry battery is used as a power source. Even if the low-horsepower DC motor 10 is used as a drive source, the lid 3 can be opened and closed smoothly.

  Further, in this trash box, the frame-like body 2 can be detached from the trash box body 1 and can be carried to the trash disposal place with the trash box body 1 alone, and only the trash box body 1 can be always kept clean by washing with water. In that case, there is no fear that the opening / closing control board 16 provided in the frame-like body 2 will be damaged by water wetting.

  Although the sensitivity setting of the infrared sensor 12 can be adjusted by the opening / closing control board 16, the opening operation switch 14 and the closing operation switch 15 want to open / close the lid 3 regardless of the setting sensitivity. To be operated on. The pilot lamp 13 is provided for displaying the setting status.

  In addition, the trash can of this embodiment has a feature that it can be easily and easily installed anywhere by using a dry battery as a power source. Of course, a commercial power source can also be used as a power source.

The perspective view of the trash can which is an Example of this invention. The center longitudinal cross-sectional view of the principal part of the trash can which is an Example of this invention. The longitudinal cross-sectional view of the principal part of the trash can which is an Example of this invention. The block diagram of the opening / closing control circuit of the trash can which is an Example of this invention.
