Description

[Technical field]

[0001] The present invention relates to a garbage disposal.

[0002] In light of the impact of the global COVID-19 pandemic, technology to properly dispose of garbage bags containing odorous garbage (such as diapers containing waste) is currently attracting attention from the perspective of hygiene management and virus infection prevention. In particular, in facilities such as hospitals, nursing homes, and daycare centers, large amounts of used diapers containing waste are generated every day, so suppressing the odor generated from used diapers stored in garbage bags is extremely important from the perspective of virus infection prevention and hygiene management.

[0003] In this regard, Patent Document 1 discloses a garbage disposal device that vacuum-disposes garbage bags that contain odor-generating materials such as used excretion care products. In the garbage disposal device disclosed in Patent Document 1, a vacuum suction nozzle connected to a vacuum suction pump is inserted into the garbage bag, and the vacuum suction nozzle sucks air from the garbage bag, creating a vacuum inside the garbage bag. After that, the opening of the garbage bag is sealed by a pair of sealing members while maintaining the vacuum state of the garbage bag. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] JP 2021-195173 A Summary of the Invention [Problem to be solved by the invention]

[0005] However, the structure of the waste disposal device disclosed in Patent Document 1 tends to be complicated. In particular, the structure of the vacuum suction nozzle tends to be complicated. Furthermore, since the waste bag needs to be held while maintaining the vacuum state inside the waste bag so that air does not enter the inside of the waste bag after the vacuum suction nozzle is pulled out from inside the waste bag, the structure of the holding mechanism for holding the waste bag also tends to be complicated. In addition, since the air inside the waste bag is sucked by the vacuum suction nozzle inserted inside the waste bag, if the waste stored in the waste bag contains liquid (for example, if the waste contains a large amount of urine or vomit), there is a risk that some of the liquid will be sucked by the vacuum suction nozzle. As a result, hygiene problems are likely to occur at the tip of the vacuum suction nozzle, and the nozzle and the vacuum suction pump are likely to break down. Thus, when considering the case where some of the waste stored in the waste bag contains liquid, there is a problem that a waste disposal device using vacuum suction noise is likely to cause problems in practical use.

[0006] To provide a garbage disposal machine that can effectively suppress odors emanating from garbage stored in a garbage bag with a relatively simple structure without using a vacuum suction nozzle or the like inserted into the inside of the garbage bag. [Means for solving the problem]

[0007] A garbage disposal according to one aspect of the present disclosure includes a housing having a vacuum chamber configured to accommodate a garbage bag containing garbage, a holding unit configured to hold the garbage bag with the opening of the garbage bag open, a vacuum pump connected to the vacuum chamber via a first vacuum hose and configured to draw air into the vacuum chamber to create a vacuum in the vacuum chamber, a sealing unit provided in the vacuum chamber and configured to seal the opening of the garbage bag, and a control unit configured to control the operation of the vacuum pump and the sealing unit. The control unit operates the vacuum pump and then operates the sealing unit. The sealing unit is configured to seal the opening after the inside of the garbage bag is in a vacuum state due to the vacuum state of the vacuum chamber.

[0008] According to the above configuration, the opening of the garbage bag is sealed after the inside of the garbage bag is in a vacuum state due to the vacuum state of the vacuum chamber. In this way, it is possible to provide a garbage disposal machine that can suitably suppress odors generated from garbage stored in the garbage bag with a relatively simple structure without using a vacuum suction nozzle or the like inserted into the inside of the garbage bag. Furthermore, even if the garbage stored in the garbage bag contains liquid, the opening of the garbage bag is sealed while maintaining the vacuum state inside the garbage bag without any liquid leaking out of the garbage bag. In this way, even if the garbage contains liquid, it is possible to suitably suppress odors generated from the garbage bag without causing any practical problems.

[0009] The garbage disposal machine may further include a degassing filter connected to the vacuum pump via a second vacuum hose and through which air sucked by the vacuum pump passes.

[0010] According to the above-mentioned configuration, the degassing filter can remove odors and bacteria from the air sucked by the vacuum pump. In this way, the air from which odors and bacteria have been removed by the degassing filter can be discharged to the outside of the garbage disposal machine.

[0011] The housing may further include a door and a partition wall facing the door. The vacuum chamber may be formed by at least the door and the partition wall. A suction hole may be formed in the partition wall. The vacuum hose may be inserted into the suction hole.

[0012] According to the above configuration, air present in the vacuum chamber is guided to the vacuum pump from the first vacuum hose inserted into the suction hole formed in the partition wall.

[0013] The door may have a first outer surface facing the outside and a first inner surface facing the vacuum chamber, the first outer surface being located on the opposite side to the first inner surface. The garbage bag may be held by the holder while being disposed on the first inner surface.

[0014] According to the above configuration, since the garbage bag is held by the holding portion while being placed on the first inner surface of the door, the garbage bag can be set in the garbage disposal relatively easily.

[0015] The housing may further include a ceiling portion. The ceiling portion may include a second outer surface facing the outside and a second inner surface located on the opposite side to the second outer surface and at least a portion of which faces the vacuum chamber. The vacuum chamber may be formed by at least the first inner surface, the partition wall, and the second inner surface.

[0016] According to the above configuration, the door is provided on the front or side of the garbage disposal machine housing rather than on the top side (ceiling side), so that users of the garbage disposal machine can set a garbage bag on the inside surface of the door relatively easily.

[0017] The sealing unit may have a first sealing unit provided on the first inner surface and a second sealing unit facing the first sealing unit across the garbage bag. The garbage disposal may further include a drive unit configured to move the second sealing unit toward the garbage bag. The control unit may operate the drive unit to move the second sealing unit toward the garbage bag after the inside of the garbage bag is in a vacuum state due to the vacuum state of the vacuum chamber, and operate the first sealing unit and the second sealing unit so that the opening of the garbage bag is sealed by the first sealing unit and the second sealing unit. Effect of the Invention

[0018] According to the present disclosure, a garbage disposal machine can be provided that is capable of effectively suppressing odors generated from garbage stored in a garbage bag with a relatively simple structure, without using a vacuum suction nozzle or the like that is inserted inside the garbage bag.

[0020] Hereinafter, the waste disposal machine 1 according to this embodiment will be described with reference to the drawings. FIG. 1 is a schematic diagram showing the front of the waste disposal machine 1 according to this embodiment. FIG. 2 is a schematic diagram showing the left side of the waste disposal machine 1. FIG. 3 is a schematic diagram showing the waste disposal machine 1 with the door 20 open. In the following description, the X-axis, Y-axis, and Z-axis set relative to the waste disposal machine 1 will be mentioned. One of these three axes is perpendicular to the remaining two axes. The Z-axis direction is the up-down direction, and includes the +Z-axis direction (upward) and the -Z-axis direction (downward). The X-axis direction is the left-right direction, and includes the +X-axis direction (rightward) and the -X-axis direction (leftward). The Y-axis direction is the front-rear direction, and includes the +Y-axis direction (forward) and the -Y-axis direction (rearward).

[0021] As shown in Figures 1 to 3, the exterior of the waste disposal machine 1 has a rectangular parallelepiped shape. The housing 2 of the waste disposal machine 1 includes a door 20, a left side wall 23, a right side wall 24, a rear wall 29, a bottom 22, and a ceiling 21. The door 20 can be opened and closed, and is provided with a handle 26 that allows a user to open and close the door 20. The ceiling 21 is provided with an operation switch 4 that allows a user to start the waste disposal machine 1, and a control unit 3 that is communicatively connected to the operation switch 4. The control unit 3 is disposed inside the ceiling 21.

[0022] The control unit 3 is configured to control each operation of the garbage disposal machine 1. In particular, the control unit 3 is configured to operate the vacuum pump 8, the electric actuator 7 (an example of a drive unit), and the seal heaters 5a, 5b (an example of a sealing unit) in response to a user's input operation (switch operation) on the operation switch 4 (see FIG. 4). The control unit 3 may be configured as, for example, a PLC (Programmable Logic Controller). The control unit 3 may include one or more processors, one or more memories, an input interface circuit, and an output interface circuit. The processor includes, for example, at least one of a CPU (Central Processing Unit) and an MPU (Micro Processing Unit). The memory includes a ROM (Read Only Memory) and a RAM (Random Access Memory).

[0023] The input interface circuit is communicatively connected to, for example, a sensor (not shown) and an operation switch 4, and is configured to receive a sensor signal output from the sensor and an operation signal output from the operation switch 4. The output interface circuit is communicatively connected to the vacuum pump 8, the electric actuator 7, and the seal heaters 5a, 5b, and is configured to output control signals to these devices.

[0024] Although not shown in FIG. 1, the garbage disposal machine 1 may be equipped with a display unit (e.g., an LCD display, etc.) that shows setting information and operating information of the garbage disposal machine 1, a touch panel configured to accept input operations from the user and arranged on top of the display unit, and an audio output unit (e.g., a speaker) that outputs audio guidance to the outside.

[0025] As shown in FIG. 3, the door 20 is configured to rotate around a rotation axis (not shown) parallel to the X-axis direction so as to form a predetermined angle with respect to the Z-axis direction. The maximum inclination angle of the door 20 with respect to the Z-axis direction is not particularly limited. When the door 20 is in an open state, an inner surface 223 (an example of a first inner surface) of the door 20 is exposed to the outside. A handle 26 is provided on an outer surface 221 (an example of a first outer surface) of the door 20 facing the outside. The inner surface 223 is located on the opposite side to the outer surface 221 and faces the vacuum chamber S (see FIG. 4). A seal heater 5a (an example of a first sealing portion) and a holding portion 6 are provided on the inner surface 223.

[0026] Next, the internal structure of the waste disposal machine 1 will be described in detail with reference to Figures 4 and 5. Figure 4 is a schematic diagram showing a cross section of the waste disposal machine 1 cut along the Z-axis direction. Figure 5 shows a cross section of the waste disposal machine 1 cut along the Z-axis direction, and is also a diagram showing a state in which a waste bag 40 is set in the waste disposal machine 1. Please note that in Figures 4 and 5, the cut surface of the waste disposal machine 1 is not hatched.

[0027] As shown in FIGS. 4 and 5, the housing 2 is provided with a vacuum chamber S. The vacuum chamber S is configured to accommodate a garbage bag 40 containing garbage G. When the door 20 is closed (as shown in FIG. 2), the vacuum chamber S is configured with the door 20, the partition wall 28, the ceiling portion 21, the bottom portion 22, the left side wall portion 23 (see FIG. 3), and the right side wall portion 24. More specifically, the vacuum chamber S is configured with the inner surface 223 of the door 20, the partition wall 28, the inner surface 213 of the ceiling portion 21, the inner surface 225 of the bottom portion 22, the inner surface of the left side wall portion 23 (not shown), and the inner surface 243 of the right side wall portion 24. Here, the inner surface 223 of the ceiling portion 21 (an example of a second inner surface) is located on the opposite side to the outer surface 212 of the ceiling portion 21 (an example of a second outer surface) facing the outside. A part of the inner surface 223 faces the vacuum chamber S.

[0028] Next, the garbage bag 40 will be described with reference to Fig. 5 and Fig. 6. Fig. 6 is a schematic diagram showing the garbage bag 40 held by the holder 6 provided on the inner surface 223 of the door 20. The garbage bag 40 is made of a material that can be vacuum packaged. The garbage bag 40 has, for example, a weldable film on the inside. The weldable film may be a synthetic resin film such as a polyethylene film or a polypropylene film.

[0029] 5 and 6, trash bag 40 has one surface 142, the other surface 143, a storage space 43 formed by surfaces 142, 143, for storing trash G, and an opening 42 communicating with storage space 43. The trash G is, for example, trash that generates an odor, and may be, for example, used diapers containing filth such as feces and urine, or food waste generated during cooking, etc. The trash bag 40 is placed on the inner surface 223 of door 20, and is held by a holder 6 provided on the inner surface 223 with opening 42 open.

[0030] Both ends of holding portion 6 are fixed to inner surface 223. Holding portion 6 is formed, for example, in a belt shape. A portion of garbage bag 40 is sandwiched between holding portion 6 and inner surface 223, and garbage bag 40 is fixed to inner surface 223 by the biasing force of holding portion 6. The shape of holding portion 6 is not particularly limited.

[0031] One surface 142 of the garbage bag 40 faces the seal heater 5a. The other surface 143 of the garbage bag 40 faces the seal heater 5b (an example of a second sealing portion) when the door 20 is closed. When the door 20 is closed, the seal heaters 5a and 5b are provided inside the vacuum chamber S. The seal heaters 5a and 5b are configured to seal the opening 42 of the garbage bag 40 in which garbage G is stored by thermal compression bonding.

[0032] The seal heater 5b is attached to the tip of a drive shaft 17 provided on the electric actuator 7. The electric actuator 7 is provided in the vacuum chamber S on the inner surface 213 of the ceiling portion 21. The electric actuator 7 is configured to move the seal heater 5b in the +Y-axis direction. In particular, the electric actuator 7 is configured to move the seal heater 5b toward the garbage bag 40 by extending the drive shaft 17 in the +Y-axis direction. With the seal heater 5b in contact with the other surface 143 of the garbage bag 40, a part of the garbage bag 40 near the opening 42 is thermally compressed by the seal heaters 5a and 5b. As a result, the opening 42 of the garbage bag 40 is sealed by the seal heaters 5a and 5b.

[0033] When the door 20 is closed, the partition wall 28 faces the inner surface 223 of the door 20 via the vacuum chamber S. The partition wall 28 is provided in the internal space 100 of the housing 2, and extends from the bottom 22 to the ceiling 21 in the Z-axis direction to form the vacuum chamber S, and extends from the left side wall 23 to the right side wall 24 in the X-axis direction. An upper end 281 of the partition wall 28 is fixed to the inner surface 213 of the ceiling 21, and a lower end 282 of the partition wall 28 is fixed to the inner surface 225 of the bottom 22. Similarly, a left end (not shown) of the partition wall 28 is fixed to the inner surface (not shown) of the left side wall 23, and a right end (not shown) of the partition wall 28 is fixed to the inner surface 243 of the right side wall 24.

[0034] A suction hole 30 is formed in the partition wall 28. The suction hole 30 communicates with the vacuum chamber S and an internal space 100 other than the vacuum chamber S. One end of a vacuum hose 10 (an example of a first vacuum hose) is inserted into the suction hole 30. An air intake cover 32 is provided on the partition wall 28 so as to cover the opening of the vacuum hose 10. The other end of the vacuum hose 10 is connected to the vacuum pump 8. In this manner, the air present in the vacuum chamber S is guided to the vacuum pump 8 via the vacuum hose 10.

[0035] The vacuum pump 8 is provided inside the bottom portion 22 and is connected to the vacuum chamber S via a vacuum hose 10. The vacuum pump 8 is configured to create a vacuum in the vacuum chamber S by sucking air from the vacuum chamber S.

[0036] The degassing filter 9 is provided inside the bottom 22, and is connected to the vacuum pump 8 via a vacuum hose 11 (an example of a second vacuum hose). The degassing filter 9 is configured to allow air from the vacuum chamber S sucked by the vacuum pump 8 to pass through. The degassing filter 9 can remove odors and bacteria from the air sucked by the vacuum pump 8. In this way, the air from which odors and bacteria have been removed by the degassing filter 9 can be discharged to the outside of the garbage disposal machine 1 via the vacuum hose 12.

[0037] (Garbage disposal method using garbage disposal device 1) Next, a series of steps in waste disposal using the waste disposal machine 1 will be described below with reference to FIG. 7. FIG. 7 is a flow chart for explaining a series of operations of the waste disposal machine. First, a user who uses the waste disposal machine 1 opens the door 20 and places the waste bag 40 containing waste G on the inner surface 223 of the door 20. At this time, as shown in FIG. 6, the waste bag 40 is held by the holding part 6 with the opening 42 of the waste bag 40 not closed, and one surface 142 of the waste bag 40 near the opening 42 faces the seal heater 5a. After completing the setting of the waste bag 40, the user closes the door 20. In this manner, the waste bag 40 is accommodated in the vacuum chamber S.

[0038] Next, in step S1, when a user operates the operation switch 4 provided on the waste disposal machine 1, the operation switch 4 transmits an operation signal to the control unit 3. In response to receiving the operation signal, the control unit 3 detects the operation of the operation switch 4 by the user. Note that, although in this example, the waste disposal machine 1 is started by the operation switch 4, the waste disposal machine 1 may also be started in response to an input operation by the user to an input interface other than the operation switch 4 (for example, a touch panel).

[0039] In step S2, the control unit 3 starts the vacuum pump 8. In response to the operation of the vacuum pump 8, the air in the vacuum chamber S is sucked by the vacuum pump 8 through the vacuum hose 10. As the air in the vacuum chamber S is sucked by the vacuum pump 8, the air in the vacuum chamber S gradually decreases. As the air in the vacuum chamber S decreases, the air present in the storage space 43 (inside the garbage bag 40) of the garbage bag 40 present in the vacuum chamber S is also led to the vacuum chamber S from the opening 42. Here, since the opening 42 is not completely closed, the storage space 43 communicates with the vacuum chamber S through the opening 42. Thereafter, the air led from the storage space 43 to the vacuum chamber S (especially the air containing odors and bacteria) is sucked by the vacuum pump 8 through the vacuum hose 10. In this way, as the air in the vacuum chamber S decreases, the air in the storage space 43 of the garbage bag 40 also decreases. As a result, the inside of the garbage bag 40 becomes a vacuum state due to the vacuum state of the vacuum chamber S.

[0040] The air sucked by the vacuum pump 8 passes through the degassing filter 9 via the vacuum hose 11. After that, odorous components and bacteria contained in the air are removed by the degassing filter 9, and the sucked air is discharged to the outside of the garbage disposal machine 1 via the vacuum hose 12.

[0041] The operating conditions of the vacuum pump 8 (for example, operating time, etc.) may be set in advance, or may be changed as appropriate in response to an input operation by the user via a touch panel (not shown).

[0042] After the storage space 43 for the garbage bag 40 is in a vacuum state due to the vacuum chamber S being in a vacuum state, the control unit 3 starts the electric actuator 7 (step S3). The control unit 3 may determine the vacuum state of the vacuum chamber S and the storage space 43 for the garbage bag 40 by comparing the time required to achieve a vacuum state of the vacuum chamber S and the storage space 43 for the garbage bag 40 with the time counted by the control unit 3 itself. The control unit 3 may also determine the vacuum state of the vacuum chamber S based on a sensor signal from a sensor (not shown) provided in the vacuum chamber S.

[0043] 5, in step S3, electric actuator 7 extends drive shaft 17 in the +Y-axis direction to move seal heater 5b toward trash bag 40. Thereafter, seal heater 5b comes into contact with the other surface 143 of trash bag 40. Control unit 3 may determine that seal heater 5b has come into contact with the other surface 143 by comparing the time required for seal heater 5b to come into contact with the other surface 143 of trash bag 40 with the time counted by control unit 3 itself.

[0044] Next, the control unit 3 operates the seal heaters 5a and 5b. Through the operation of the seal heaters 5a and 5b, the vicinity of the opening 42 of the garbage bag 40 is thermally compressed by the seal heaters 5a and 5b, and as a result, the opening 42 of the garbage bag 40 is sealed by the seal heaters 5a and 5b (step S4). After that, the control unit 3 operates the electric actuator 7 so that the drive shaft 17 contracts in the -Y axis direction. Next, in step S5, the control unit 3 notifies the outside of a message indicating that garbage processing has been completed. At this point, the control unit 3 may light or blink an indicator (not shown) to present the message to the outside. In addition, the control unit 3 may operate a speaker (not shown) so that the speaker outputs a voice guidance related to the message. Furthermore, the control unit 3 may display the message on a display (not shown). After checking the message, the user can open the door 20 to remove the vacuum-packaged garbage bag from the garbage processing machine 1.

[0045] According to this embodiment, the opening 42 of the garbage bag 40 is sealed after the storage space 43 of the garbage bag 40 is in a vacuum state due to the vacuum state of the vacuum chamber S. In this way, it is possible to provide a garbage disposal device 1 that can suitably suppress odors generated from garbage G stored in the garbage bag 40 with a relatively simple structure without using a vacuum suction nozzle or the like inserted into the storage space 43 of the garbage bag 40. Furthermore, even if the garbage G stored in the garbage bag 40 contains liquid matter (for example, garbage containing a large amount of liquid filth such as urine or vomit, or food waste containing a large amount of water), a part of the liquid matter remains in the storage space 43. Therefore, the opening 42 of the garbage bag 40 is sealed while the vacuum state inside the garbage bag 40 is maintained without the liquid matter leaking out into the vacuum chamber S. In this way, even if the garbage G contains liquid matter, it is possible to suitably suppress odors generated from the garbage bag 40 without causing any practical problems. Therefore, it is possible to provide a garbage disposal device 1 that is very useful in terms of virus infection prevention and hygiene management.

[0046] In addition, since the garbage bag 40 is held by the holding portion 6 while being placed on the inner surface 223 of the door 20, the garbage bag 40 containing garbage G can be set relatively easily inside the garbage disposal machine 1.

[0047] Furthermore, in this embodiment, since the door 20 is provided on the front side of the housing 2, not on the ceiling side, even a relatively short user can relatively easily set the garbage bag 40 on the inner surface 223 of the door 20. In particular, even if the overall height of the housing 2 becomes large depending on the height of the vacuum pump 8, the door 20 on which the garbage bag 40 is placed is provided on the front side. Therefore, even a relatively short user or a disabled person using a wheelchair can use the garbage disposal machine 1 relatively easily.

[0048] Although the embodiment of the present invention has been described above, the technical scope of the present invention should not be interpreted as being limited by the description of the embodiment. The embodiment is an example, and it is understood by those skilled in the art that various modifications of the embodiment are possible within the scope of the invention described in the claims. The technical scope of the present invention should be determined based on the scope of the invention described in the claims and its equivalents.

[0049] For example, the control unit 3 starts the electric actuator 7 after the storage space 43 for the garbage bag 40 is in a vacuum state due to the vacuum chamber S being in a vacuum state, but this embodiment is not limited to this. In this regard, the control unit 3 may start driving the electric actuator 7 before the storage space 43 for the garbage bag 40 is in a vacuum state due to the vacuum chamber S being in a vacuum state. In this case, the seal heater 5b moves to a position a predetermined distance away from the garbage bag 40. Thereafter, after the storage space 43 is in a vacuum state, the electric actuator 7 moves the seal heater 5b so that the seal heater 5b abuts against the other surface 143 of the garbage bag 40.
