Technical Field
[0001] The present disclosure relates to a collecting apparatus and, more specifically, to a trash and garbage collecting apparatus using a bag, the apparatus being configured to discard the bag, trash, and garbage into a trash bin at the same time, and to keep a collection container, the trash bin, and an area around the trash bin clean.
Background Art
[0002] In general, a vacuum cleaner is a cleaning device designed to suck up dust and the like by using air pressure differences. Specifically, a vacuum cleaner cleans by sucking dust from carpeted living room floors using a difference in air pressure.
[0003] FIG. 32 is a concept view illustrating an existing trash collecting apparatus. Referring to FIG. 32, the existing trash collecting apparatus includes a suction port, a vacuum suction device, a separating device, a collection container, a bag-supporting container, and a collection bag.
[0004] First, the vacuum suction device sucks air to change the inside space of the trash collecting apparatus into a vacuum state. Then, dust, debris, garbage dirt, and air are sucked through the suction port by a pressure difference.
[0005] Therefore, the separating device filters trash such as dust, debris, garbage dirt, and the like sucked by a pressure difference. In addition, trash such as dust, debris, garbage, and the like are collected in the collection bag provided in the bag-supporting container. In addition, air is discharged outward through the vacuum suction device.
[0006] However, an upper portion of the collection bag and an upper portion of the bag-supporting container of the existing trash collecting apparatus are open. Therefore, when the vacuum cleaner is operated, a lot of dust, debris, and garbage get stuck on a lower surface of the separating plate 23 provided at a lower portion of the separating device.
[0007] Accordingly, there is a problem of contaminating the lower surface of the separating plate due to remaining dust, debris, and garbage. Therefore, a user should separate the separating device from the vacuum cleaner, and then wipe the lower surface of the separating plate to remove a lot of dust, debris, and garbage, and clean the separating plate periodically.
[0008] Furthermore, the existing trash collecting apparatus includes a suction tube provided outside the separating device, and one portion of the suction tube is connected to an outer portion of the collection container, so that when the collection container is attached and detached, there is a great risk of damage or destruction to the suction tube.
[0009] Furthermore, for the existing trash collecting apparatus, the suction tube is bent twice, and the diameter of the suction tube is formed small, resulting in a problem that air is not properly sucked from the flow space between the collection container and the collection bag to the passage portion.
Disclosure Technical Problem
[0010] The present disclosure has been made keeping in mind the above problems occurring in the related art, and an objective of the present disclosure is to provide a trash and garbage collecting apparatus using a bag, and the apparatus includes a bag fixing means to efficiently mount and separate an upper end of a collection bag to and from a part of a separating container in a separating device, and a suction passage provided at a part of the separating device and communicating with a collection container and a passage portion, so that the apparatus is capable of efficiently attaching and detaching the collection container to and from the separating device, and there is no longer a need for a bag supporting container for supporting the collection bag in the collection container.
[0011] Another objective of the present disclosure is to provide a trash and garbage collecting apparatus using a bag, the apparatus being configured to gather and fit, at a portion of a separating plate, an upper portion of a collection bag collecting trash and garbage therein between a nozzle through which trash and garbage are transferred and a nozzle cap securely fitted over the nozzle, so that there is no risk of dust, debris, and garbage stuck on a lower surface of the separating plate.
[0012] Yet another objective of the present disclosure is to provide a trash and garbage collecting apparatus using a bag, the apparatus including a suction passage provided at a portion of a separating device and formed long in a direction of gravity, and a collection container attached and detached separately from the suction passage, so that there is no risk of damage or destruction to the suction passage, and air is efficiently sucked from a flow space between the collection container and a collection bag to a passage portion.

Mode for Invention
[0034] Hereinafter, exemplary embodiments of the present disclosure will be described in detail with reference to accompanying drawings such that the technical idea of the present disclosure can be easily embodied by one of ordinary skill in the art to which this present disclosure belongs.
[0035] However, the following embodiments are merely examples to help understand the present disclosure, and the scope of the rights of the present disclosure is not reduced or limited thereto. Furthermore, the present disclosure may be implemented in many different forms and is not limited to the embodiments described herein.
[0036] First, according to the present disclosure, a trash and garbage collecting apparatus 10 using a bag will be described.
[0037] FIG. 1 is a concept view illustrating a trash and garbage collecting apparatus 10 using a bag according to the present disclosure.
[0038] Referring to FIG. 1, according to the present disclosure, the trash and garbage collecting apparatus 10 using a bag includes a suction port 15, a separating device 20, a vacuum suction device 27, a passage portion 28, a collection container 30, a collection bag 40, and a suction passage 45a.
[0039] First, the suction port 15 is a passage through which trash, garbage, and air are sucked. At this point, the suction port 15 is formed in a circular pipe shape that is transversely long.
[0040] Furthermore, the separating device 20 communicates with the suction port 15 and serves to separate trash, garbage, and air introduced through the suction port 15 from each other. Specifically, the separating device 20 communicates with the suction port 15, and trash and garbage are separated from air inside the separating device 20.
[0041] At this point, the separating device 20 is formed in a hollow cylinder or elliptical cylinder.
[0042] Furthermore, the vacuum suction device 27 is provided at an outlet side of the separating device 20 and sucks trash, garbage, and air through the suction port 15 and the separating device 20 in communication with the suction port 15. At this point, the vacuum suction device 27 is installed at an upper portion of the separating device 20.
[0043] A first portion and a second portion of the passage portion 28 communicate respectively with the separating device 20 and the vacuum suction device 27, so that the passage portion 28 connects the separating device 20 and the vacuum suction device 27 to each other.
[0044] The collection container 30 is provided at a lower portion of the separating device 20. At this point, the collection container 30 is empty and has a shape of which a part of an upper portion is open.
[0045] Air sucked through the suction port 15 passes through the separating device 20 and then is discharged outward by the vacuum suction device 27. Furthermore, trash and garbage sucked through the suction port 15 pass through the separating device 20 and then are accommodated in the collection container 30 by a centrifugal force.
[0046] Furthermore, the collection bag 40 is provided in the collection container 30, and trash introduced through the separating device 20 is accommodated in the collection bag 40. At this point, the collection bag 40 may be made of vinyl, paper, or other materials.
[0047] Furthermore, a space between the collection bag 40 and the collection container 30 is a flow space 41 through which air flows.
[0048] Referring to FIG. 1, the separating device 20 includes a body part 21 and a separating container 21a.
[0050] Furthermore, the separating container 21a is provided in the body part 21 and accommodates trash, garbage, and air sucked from the suction port 15. At this point, the separating container 21a has an empty inside part, and a cross section of the separating container 21a is formed in a circle or an ellipse.
[0051] Meanwhile, the suction passage 45a is provided in a space between an inside part of the body part 21 and an outside part of the separating container 21a. A lower end and an upper end of the suction passage 45a communicate respectively with an inner upper portion of the collection container 30 and an inner lower portion of the passage portion 28. Therefore, the suction passage 45a is a passage through which air included in the flow space 41 between the collection bag 40 and the collection container 30 is sucked.
[0052] In other words, air included in the flow space 41 between the collection bag 40 and the collection container 30 passes through the suction passage 45a and the passage portion 28 and then flows to the vacuum suction device 27.
[0053] Furthermore, the lower end of the suction passage 45a communicates with the inner upper portion of the collection container 30 and serves as a passage through which air introduced from the flow space 41 flows.
[0054] Furthermore, the upper end of the suction passage 45a communicates with the inner lower portion of the passage portion 28 and serves as a passage through which air introduced from the flow space 41 is discharged.
[0055] The air introduced from the flow space 41 passes through the suction passage 45a and the passage portion 28 and then is discharged to the vacuum suction device 27.
[0057] Furthermore, the separating plate 23 is provided at a lower portion of the separating container 21a and separates the separating container 21a from the collection container 30. At this point, the separating plate 23 is horizontally flat in a circular plate shape or an elliptic plate shape of a predetermined thickness.
[0058] The bag fixing means is provided at the separating container 21a to fix an upper end of the bag and may include a nozzle 23a and a nozzle cap 23b.
[0059] The nozzle 23a is formed at one portion of a lower surface of the separating plate 23, communicates with the separating container 21a and the collection container 30, and serves as a passage through which trash and garbage passing through the separating container 21a are transferred. At this point, the nozzle 23a is provided at an upper portion of an inside part of the collection container 30 and has a circular pipe shape with open upper and lower portions, the shape being formed in the direction of gravity.
[0060] Trash and garbage sucked through the suction port 15 pass through the separating container 21a and the nozzle 23a of the separating plate 23 and then are accommodated in the collection bag 40.
[0061] Furthermore, the nozzle cap 23b is fitted over and coupled to an outer circumferential surface of the nozzle 23a to gather an upper portion of the collection bag 40 and attach it in a one-touch manner. At this point, the nozzle cap 23b has a circular pipe shape formed in a direction of gravity. An inner diameter of the nozzle cap 23b is formed in a size corresponding to an outer diameter of the nozzle 23a so that the nozzle cap 23b and the nozzle 23a may be fastened to each other.
[0062] Specifically, the upper portion of the collection bag 40 is securely fitted between the outer circumferential surface of the nozzle 23a and an inner circumferential surface of the nozzle cap 23b in a one-touch manner.
[0063] Thereafter, the separating device 20 is coupled to the collection container 30 while a central portion and a lower portion of the collection bag 40 are disposed inside the collection container 30.
[0064] According to the present disclosure, the trash and garbage collecting apparatus 10 using a bag includes the nozzle 23a and the nozzle cap 23b to which the collection bag 40 are attached in a one-touch manner, and the suction passage 45a provided in a part of the inside space of the separating device 20 and communicating with the collection container 30 and the passage portion 28. Therefore, attachment and detachment of the collection container 30 to and from the separating device 20 are easily performed. Moreover, there is no longer a need for a bag-supporting container 35 in the collection container 30 to support the collection bag 40.
[0065] Furthermore, according to the present disclosure, the trash and garbage collecting apparatus 10 using a bag is configured to gather and fit over the upper portion of the collection bag 40 which is capable of collecting trash and garbage in a one-touch manner between the nozzle 23a through which trash and garbage are transferred at one side of the separating plate 23 and the nozzle cap 23b securely fitted over an outer portion of the nozzle 23a. Therefore, dust and residue do not stick to the separating plate 23, and a lower surface of the separating plate 23 can be kept clean, which is an advantage.
[0066] In addition, according to the present disclosure, for the trash and garbage collecting apparatus 10 using a bag, when the collection bag 40 is detached, it is possible to prevent trash particles from leaking out of the collection bag 40 in advance, and it is easy to prepare the collection bag 40, which is an advantage.
[0067] Meanwhile, a second portion of the vacuum suction device 27 includes an outlet filter 46 filtering fine dust included in air passing through the vacuum suction device 27.

[0147] Referring to FIG. 30, the outlet 24 and the suction filter 24a are provided in the vacuum suction device 27, not in the passage portion 28.
[0148] FIG. 31 is a front-sectional view illustrating the trash and garbage collecting apparatus with the separating plate 26, a hemispherical collection container 30, and an arch passage portion 28.
[0149] Referring to FIG. 31, the conical separating plate 26 may have a conical shape with the diameter being reduced in a direction from the upper portion to the lower portion thereof.
[0150] Furthermore, a lower portion of the collection container 30 may have a hemispherical shape to expand the space occupied by the collection bag 40.
[0151] At this point, the suction passage 45a may be formed in the space between the body part 21 and the separating container 21a.
[0152] Furthermore, an upper portion of the passage portion 28 may have an arch shape to expand a space where air passing through the outlet 24 and the suction filter 24a flows.
[0153] The vacuum suction device 27 and the passage portion 28 are connected to a passage having a circular pipe shape.
[0154] In other words, a first end of the vacuum suction device 27 may communicate with the passage portion 28, and a second end of the vacuum suction device 27 may communicate with the outlet filter 46.
[0155] Meanwhile, the pressure of air in the vacuum suction device 27 is defined by a suction pressure P1. The pressure of air in the collection bag 40 is defined by an internal pressure P2. The pressure of air in the flow space 41 between the collection container 30 and the collection bag 40 is defined by a spatial pressure P3.
[0156] Referring to FIG. 3, trash and garbage sucked by the vacuum suction device 27 pass through the suction port 15, the separating device 20, and the nozzle 23a, and then are accommodated in the collection bag 40 inserted in the collection container 30.
[0157] Furthermore, air sucked by the vacuum suction device 27 passes through the suction port 15, the separating device 20, the through holes 22a of the conical basket 22, the outlet 24, the suction filter 24a, and the passage portion 28, and then is discharged outward through the vacuum suction device 27 and the outlet filter 46.
[0158] Therefore, at the conical basket 22, a pressure drop may occur in the air passing through the through holes 22a of the conical basket 22. In other words, the suction pressure P1 is formed lower than the internal pressure P2 by the pressure drop value ΔP.
[0159] Furthermore, the lower end and the upper end of the suction passage 45a communicate respectively with the collection container 30 and the passage portion 28 provided at the upper portion of the separating device 20. Therefore, the spatial pressure P3 is formed equal to the suction pressure P1.
[0160] Therefore, the spatial pressure P3 is formed lower than the internal pressure P2 by the pressure drop value ΔP.
[0161] Accordingly, the collection bag 40 may have a shape inflated toward the inner circumferential surface of the collection container 30 by air having the internal pressure P2. Therefore, the shape and size of the collection bag 40 are changed to be similar to the collection container 30.
[0162] According to the present disclosure, the trash and garbage collecting apparatus using a bag includes the bag fixing means which allows the collection bag to be attached in a one-touch manner, and the suction passage at a part of the inside space of the separating device which communicates with the collection container and the passage portion. Therefore, it is easy to attach and detach the collection container to and from the separating device, and there is no longer a need for a bag-supporting container to support the connection bag in the collection container.
[0163] Furthermore, according to the present disclosure, the trash and garbage collecting apparatus using a bag is configured to gather and insert the upper portion of the collection bag collecting trash and garbage in a one-touch manner by the bag fixing means. Therefore, dust and residue do not stick to the lower surface of the separating plate, and the lower surface of the separating plate can be kept clean, which is an advantage.
[0164] In addition, according to the present disclosure, for the trash and garbage collecting apparatus using a bag, when the collection bag is detached, it is possible to prevent trash particles from leaking out of the collection bag in advance, and it is easy to prepare the collection bag, which is an advantage.
[0165] Furthermore, according to the present disclosure, the trash and garbage collecting apparatus using a bag includes the suction passage which is formed long in the space between the outer part of the separating container and the inner part of the body part in a direction of gravity and has an inner diameter formed greater than an existing diameter. Therefore, there is no risk of damage or destruction of the suction passage, and moreover, air can be efficiently sucked from the flow space between the collection container and the collection bag to the passage portion.
[0166] Furthermore, according to the present disclosure, the trash and garbage collecting apparatus using a bag is configured to discard the bag and trash into a trash bin, and the collection container, and to always keep the trash bin and the area around the trash bin clean.
[0167] As described above, the present disclosure has the technical idea of mainly providing the trash and garbage collecting apparatus 10 using a bag. The embodiments described above with reference to the accompanying drawings are only embodiments, and the real scope of the rights of the present disclosure is based on the scope of the patent claims, but also extends to various equivalent embodiments that may exist.
