In addition, the conventional garbage inlet has a problem that the size of the inlet is greatly changed according to the garbage pay-as-you-go bag to damage the surrounding landscape of the residential area.

In addition, the conventional waste inlet opening is opened to the user who does not use the pay-as-you-go bag, so that it is not possible to appropriately cope with the waste-based used in each region.

In addition, in the related art, when the number of households in charge of the waste inlet increases due to a constant storage capacity at the top of the discharge valve, the installation cost increases greatly by additionally installing the waste inlet.

In addition, the inner surface of the lower connection portion of the waste inlet and the outer surface of the lower side of the waste inlet valve may be directly connected to the waste conveying pipe to generate a lot of corrosion, and when corrosion occurs, repair costs increase.

The object of the present invention is convenient to use in view of the above-mentioned conventional problems, and also looks good, meets the waste-based agent, can completely block the smell of food to the outside, and simply change the storage capacity at no additional cost. It is to provide a trash can.

In the present invention, in order to achieve the above object, when the trash is in contact with the pay-as-you-go garbage bag recognition system, the lock of the trash inlet door is released. After that, the entrance door is opened to inject waste, and when the foot switch is released, the entrance door is closed, and the safety cover is returned to its original position, and the waste introduced into the lower part is temporarily stored in the chute of the lower (underground) valve of the waste inlet. Each discharge valve is opened when the garbage is automatically collected from the storage, and the auxiliary air inlet is automatically opened due to the pressure difference due to the negative pressure when the garbage discharge valve is opened. The waste that was being stored has an air flow that creates a vacuum. Is moved to the carrier hub via a conveying pipe, there is provided a garbage charging port of the discharge valve is closed when the auxiliary air intake is also a self-locking so that the vacuum refuse collection system.

In addition, when the inlet door is open, the discharge valve does not open when the garbage is collected from the storage, it is automatically moved to the next process.

In addition, the outside of the connection part is coated with a special paint on the inside and outside to prevent corrosion, to insulate the connection parts of the lower and upper to prevent the anode (Anode) discharge to the atmosphere, the trash that can cause the most corrosion The inner surface of the lower connection part of the inlet port and the outer surface of the lower side of the waste inlet valve are prevented from being exposed to the corrosion conditions of the conveying pipe to prevent corrosion, and the maintenance of the inner surface of the lower connection part of the waste inlet port is possible for partial plural. As a result, the lifespan is extended.

In addition, the garbage inlet of the vacuum waste collection system is an external connection device consisting of an input device for knowing the state of the external device and an output device for controlling the external device, and a pay-as-you-go bag detection capable of detecting the metal paint of the pay-per-bag. A contactless magnetic device comprising a sensor, a control device which acts to release a door lock key by outputting a signal to a peripheral device through an external connection device by a control device when a signal is input from the sensor, and a power supply device that supplies power to the system.

Figure 1 shows an overall cross-sectional view of the circular type of the waste inlet (CS) of the vacuum waste collection system according to the present invention.

In the garbage inlet according to the present invention, in order to discard the garbage, when the waste-based garbage bag is brought into contact with the meter-based recognition system 4-1 described later, the locking device of the garbage inlet door 4-4 is released, and the foot switch 4-2 ), The safety cover (3-2) is rotated downward to close the inside of the chute (see Figures 1a, 2a and 3a), so that only a certain amount of waste can be introduced and affect the vacuum waste collection system. The long length or bulky playful waste is not prevented or the input of garbage that does not meet the standard is prevented, and the inlet door 4-4 is opened after the safety cover 3-2 is rotated downward to open the garbage. The input door 4-4 is closed when the foot switch 4-2 is released. In addition, as the safety cover 3-2 returns to its original position, the garbage falls down.

The waste thus injected is temporarily stored in the chute of the lower (underground) valve 3 of the waste inlet, and when each waste is automatically collected from the storage, each discharge valve 3-3 is opened and the auxiliary air inlet ( 3-4) is a check valve type which is automatically opened due to a pressure difference when the waste discharge valve is opened as described above, and when the valve is opened, the waste which is temporarily stored in the chute is formed with an air flow to form a vacuum. It is moved to the storage via the transfer pipe (1). In addition, the auxiliary air intake port 3-4 is automatically closed when the discharge valve 3-3 is closed.

If the inlet door (4-4) is open, the discharge valve (3-3) does not open automatically when moving to the next process when collecting garbage in the collection. On the contrary, when the discharge valve 3-3 is opened, the closing door 4-4 does not open. Thus, the inlet door (4-4) and the discharge valve (3-3) is opened at the same time to provide a safety plate function to prevent a safety accident, such as a person sucked.

When a certain amount of garbage temporarily stored in the garbage inlet is accumulated, the level switch (3-1) is activated to display the trash full on the display panel (4-3), the garbage inlet door (4-4) is not opened.

The lower (underground) connection part 2 of the garbage inlet according to the present invention is a space provided to protect the outside of the lower valve 3 and to maintain and repair it. The outside of the connection part 2 is coated with a special paint on the inside and the outside to prevent corrosion, and insulates the connection part of the lower part 2-2 and the upper part 2-3 to prevent the anode from being discharged to the atmosphere. . In the case of corrosion of the connection part 2, since corrosion by the potential difference is more than corrosion by oxygen, the upper part (2-) of the connection part 2 is prevented to prevent anode discharge at the part connected to the ground. By providing an insulator at the boundary between 3) and the lower part 2-2, the potential difference is balanced to prevent electrical corrosion. A person can enter and maintain and repair through the inspection port 2-1 of the connector 2. The housing 4 of the garbage inlet and the upper portion 2-3 of the connecting portion 2 are integrally formed so that the appearance of the surface exposed to the ground becomes beautiful. The connecting portion 2 is intended to be jointly used for each type of waste inlet.

The lower (underground) valve 3 of the waste inlet according to the present invention is coated with a special paint on the outside and the inside to prevent corrosion, and where the corrosion is very severe, corrosion resistance is prevented by using corrosion resistant materials. In addition, corrosion is prevented by isolating the inner surface of the lower portion (underground) of the garbage inlet and the outer surface of the valve 3 from the corrosion conditions of the transfer pipe. The lower part 3-5 and the upper part of the lower valve 3 are completely sealed so that the smell of garbage temporarily stored in the chute is not discharged to the outside. The auxiliary air intake port 3-4 is opened only when the discharge valve 3-3 is opened by the above-mentioned differential pressure so that air can flow into the chute. In addition, the height can be adjusted deeper to the basement in the connecting portion of the upper and lower (3-5) so as to adjust the height as needed. As described above, the safety cover 3-2, the foot switch 4-2 and the garbage inlet door 3-5 are mechanically connected to secure safety. This operation employs a fast response pneumatic operation.

In the cylinder for driving the lower valve 3, the angle between the air cylinder and the link device for driving the discharge valve is inclined by about 5 ° to prevent the discharge valve from being opened automatically by weight when garbage is put into the chute. Doing.

The waste inlet outer housing (4) is designed with aesthetics in mind and secures a grill area where sufficient air flow can be introduced when driving the discharge valve, and the inlet door ( 4-4) The bottom is curved. The inlet door 4-4 is designed to be sealed to prevent the internal and external air and odors from escaping, and the grill area and the sound absorbing material are adopted so that the air noise is less than the reference value.

Next, in the pay-as-you-go envelope recognition system, there are a barcode recognition system, a logo pattern recognition system (recognizing a mark or a logo with a built-in camera), and a non-contact magnetic recognition system for recognizing a special paint. It employs the most efficient contactless magnetic recognition system. The special paint can be used by painting on the logo and designation site of each municipality.

As shown in Fig. 12, the contactless magnetic recognition system is capable of detecting a metal coating of an external connection device, a pay-as-you-go envelope made up of an input device capable of knowing the state of the external device and an output device capable of controlling the external device. Pay-as-you-go envelope detection sensor, when a signal is input from the sensor outputs a signal to the peripheral device through the external connection device by the control device, in the present invention acts to release the door lock key, a plurality of ports that can control other devices And a power supply for supplying power to the system.

Referring to Fig. 12A, the principle of the pay-as-you-go envelope detection sensor will be described in more detail. If a special paint that can be recognized by the magnetic recognizer is applied to the pay-as-you-go envelope, it can be applied to the logo or designation area. The detection unit detects the electromagnetic wave reflected from the transmitting part of the recognizer in response to the special metal coating material painted on the payload envelope. Since the detected signal is weak in signal power and cannot act at all, the signal detected by the detector is amplified as a reflected wave signal by an amplifier to operate the door lock control device in the controller to open the door lock.

The transmitter oscillates to transmit electromagnetic waves, amplifies the electromagnetic waves transmitted from the oscillator to increase the output of the oscillated signal, and the impedance matching unit performs impedance matching to prevent smooth transmission and failure of the transmitter.

15 shows a pay-as-you-go envelope recognition system using a barcode. Specifically, if the bar code is printed on the pay-per-bag, and the pay-per-bag printed with the bar code is close to the bar code reader in the inlet, the bar code value of the pay-per-bag is read by the bar code reader and scanned by the bar code value storage device. Save the barcode value. When the stored barcode value and the existing barcode value are compared with each other, the door lock control device is operated by the control driving device to open the door lock. If the metering bag is not inserted into the slot for the specified time, the slot is forcibly closed by the door lock open timer. In addition, when the metering bag is inserted into the inlet within a predetermined time, the inlet is closed by the metering bag inlet sensor regardless of the door lock open timer.

In Fig. 16, the payload envelope recognizer using the pattern recognizer is shown. A figure is printed on a pay-as-you-go envelope and the pay-as-you-go envelope with the figure is placed close to the NTSC camera in the slot. The camera scans the figure of the pay-as-you-go envelope and digitizes the data by the sync detection circuit and the device that converts the analog to digital and stores the data in the pattern storage device. Data stored in the pattern storage device is converted by the edge detection device and then stored in the pattern storage device. This pattern storage device stores data converted by the edge detection device. The converted data is rotated and moved by a center rotation detection device so that the figure does not have a position and inclination similar to the reference pattern, and is converted, and then stored in the pattern storage device. The data formed through the two conversions as described above is compared with the reference pattern. If the compared figures match each other, the door lock control device is operated by the control driving device to open the door lock. If the metering bag is not inserted into the slot for the specified time, the slot is forcibly closed by the door lock open timer. In addition, when the payload envelope is inserted into the feed opening within a predetermined time, the feed opening is closed by the payload envelope input detection sensor regardless of the door lock open timer.

The control panel 3-7 is waterproof against heavy rain and provides a heater and a filter to prevent condensate generation of compressor air in winter.

According to the waste inlet of the vacuum waste collection system according to the present invention, when opening the inlet, the internal safety device operates to provide only a certain space to the user. As a result, a number of users can defend against a mistake caused by the user using the waste inlet, and the discharge valve of the vacuum waste collection system is a safety device to block the upper vacuum during operation (opening). It is possible to fundamentally block the input of long and bulky wastes that could cause the waste collection system to shut down.

In addition, by installing a foot switch, the problem of hygiene when opening the door with the handle as the multiple users use the garbage inlet is solved, and when the garbage door is opened by hand, the garbage bag is heavy This inconvenience is solved, and when the garbage is put into both hands, the trash broth is put on the hands to solve the problem that the user is unpleasant.

By adopting the vertical (upper) feeding method, it is necessary to use both hands to put garbage horizontally, so that the inconvenience caused to the user is improved, and when the foot valve is closed, the opening is automatically opened to provide convenience to the user. Done.

By taking the same shape, the size of the inlet is greatly changed according to the waste-based bag of the conventional waste inlet, which solves the problem of surrounding landscape, and the food waste inlet, as well as the 20- to 100 liters of the waste-based bag, is the same. You can install the inlet by changing only the inlet location according to the size of the garbage bag.

The lower valve 3 is completely sealed with the inlet outer housing 4 to completely block the odor generated inside the waste inlet. When the discharge valve 3-3 is operated, the auxiliary air inlet 3-4 is closed. Is automatically opened due to the pressure difference to inhale the odor inside the discharge valve (3-3), and the auxiliary air inlet is a safety device that prevents the collection pressure of the vacuum waste collection system from being transmitted to the inlet door (4-4). It will work. By adopting a non-contact magnetic recognition system that recognizes the municipal logo on the waste-based bag and the special paint on the designated area, and opens the entrance door (4-4) only for the garbage bags used by each municipality, Users who do not use a pay-as-you-go bag will not open the entrance door, and it will be compatible with the waste pay-as-you-go system used in each region of Korea.

Since the storage capacity can be changed, in the related art, when the number of households in charge of the waste inlet increases due to a constant capacity at the top of the discharge valve 3-3, an additional waste inlet must be additionally installed, thereby greatly increasing the installation cost. By adopting the present invention, even when the number of households increases, by changing the lower side 3 and the lower connection height of the lower valve, it is possible to simply change the storage capacity at the time of construction without changing other specifications.

It can be used as a structure in which food waste can be thrown in by using food waste buckets used in ordinary households.
