Description

[Technical field]

[0001] The present invention relates to a method for cleaning irregular objects, which can clean irregular objects such as helmets for firefighters, motorcycle drivers, or factory workers, firefighter facepieces, firefighter fire boots, and fire hose attachment metal terminals with a high degree of cleanliness and high efficiency without causing damage such as scratches or deformation. [Background technology]

[0002] Firefighters need to wear helmets while fighting fires, motorbike drivers need to wear helmets while driving, and people who work in or enter factories need to wear helmets for safety. These helmets are generally semi-spherical in shape and have various protrusions and recesses, which makes them unsuitable for automatic washing in a washing machine, so they are usually washed by hand one by one.

[0003] On the other hand, a device has also been proposed in which helmets and the like are loaded into a cleaning device and mechanically cleaned. Patent Documents 1 to 3 disclose cleaning devices in which one helmet is mounted in a chamber and a cleaning liquid is sprayed onto the helmet to clean the helmet individually. Patent Document 4 discloses a cleaning device that cleans multiple (four) helmets at once. In this cleaning device, four helmets are mounted on mounting parts installed at four fixed positions spaced at equal intervals within a chamber, and each helmet is cleaned with a cleaning liquid while being prevented from moving. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] JP 2018-57991 A [Patent Document 2] JP 2016-60984 A [Patent Document 3] Utility Model Registration No. 3244271 [Patent Document 4] JP 2002-254043 A Summary of the Invention [Problem to be solved by the invention]

[0005] However, cleaning helmets manually requires the cleaner to perform tedious tasks, and the cleaning efficiency is extremely low and time-consuming. In particular, at fire stations, firefighters wash their own helmets, etc., and this causes a problem in that firefighters spend their time on incidental tasks other than their actual firefighting activities.

[0006] Furthermore, even when helmets are mechanically washed using a cleaning device, the conventional devices described in Patent Documents 1 to 3 require that one helmet be mounted at a predetermined position in a cleaning tank or cleaning chamber, and that each helmet is subjected to an individual cleaning process, making the cleaning process cumbersome and inefficient. Also, in the cleaning device described in Patent Document 4, four helmets are placed at cleaning positions set to be spaced apart at a predetermined distance, and undergo cleaning while being held in that position, so there is a limit to the number of helmets that can be washed in one process, making the cleaning efficiency low and the cleaning work cumbersome.

[0007] The present invention has been made in consideration of such problems, and has an object to provide a method for cleaning irregular objects, which can clean irregularly shaped helmets, etc., highly efficiently and without complicated processing, without damaging each other even when multiple helmets, etc. are placed in a cleaning tank. [Means for solving the problem]

[0008] The cleaning method for an irregularly shaped object according to the first aspect of the present invention comprises the steps of: A sponge-like cushioning material is placed in a first bag having a net shape and an opening, the irregular-shaped object to be cleaned is placed in the first bag, another sponge-like cushioning material is placed on top of the irregular-shaped object, and the opening of the first bag is closed. a sponge-like bottom cushioning material is placed on the bottom of a second bag having a net shape larger than the first bag and an opening, and side wall cushioning materials are placed to surround the bottom cushioning material; the first bag with the irregular object stored therein is inserted into the space surrounded by the bottom cushioning material and the side wall cushioning materials; and the opening of the second bag is closed; Then, multiple irregular-shaped objects stored in the second bag are loaded into a cleaning tank, cushioning material is loaded into the cleaning tank, and the irregular-shaped objects are washed by agitating them together with water and cleaning liquid in the cleaning tank.

[0009] In this cleaning method for irregularly shaped objects, for example, The irregularly shaped object is a firefighter's helmet or a firefighter's facepiece.

[0011] This application 2 The cleaning method for irregularly shaped objects according to the present invention comprises the steps of: In a method for cleaning a fire hose as an irregular object, A mesh bag is provided with a plurality of partitions, and a plurality of bag sections are arranged in one direction. A cushioning material is inserted into each bag section through the opening of the mesh bag. The mesh bag containing the cushioning material is then wound around a metal fitting of a fire hose. The mesh bag is then fixed to the metal fitting with a string. A plurality of fire hoses with mesh bags wound around the metal fittings are loaded into the cleaning tank, and a cushioning material is loaded into the cleaning tank. The cushioning material is then stirred together with the water and cleaning liquid in the cleaning tank. 、 The fire hose is cleaned. Effect of the Invention

[0012] In the first invention of the present application, a double bag structure is formed with a first bag containing an irregular object such as a helmet or facepiece, and a second bag larger than the first bag and containing the first bag containing the helmet, and a cushioning material is placed in the first bag and the second bag, and a plurality of these bags are placed in the cleaning tank together with the cushioning material and agitated by the water flow in the cleaning tank. At this time, the helmets, etc. are agitated by the water flow and move chaotically in the cleaning tank, colliding with the inner wall of the cleaning tank and other helmets, but since the cushioning material is placed in the first bag, and the cushioning material is placed between the second bag and the first bag, and further, the cushioning material is placed in the cleaning tank, the helmets, etc. are not damaged even if they collide chaotically. Moreover, according to the method of the present invention, a plurality of helmets, etc. are placed in the cleaning tank and washed in the same manner as in a home washing machine or a coin laundry, so that a large number of helmets can be washed efficiently with simple operations. In addition, in the present invention, an irregular object such as a helmet is placed in a first bag together with a cushioning material, and the first bag containing the irregular object is similarly placed in a second bag together with a cushioning material, and the irregular object is placed in a double bag state before being thrown into the cleaning tank, so that the irregular object is reliably prevented from being scratched by collisions when moving around chaotically in the cleaning tank. The scratch prevention effect of this double bag is superior to the case where a large amount of cushioning material is used in a single bag.

[0013] In the second invention, fire boots are placed in a mesh bag and washed in a cleaning tank. In the third invention, a mesh bag containing cushioning material is wrapped around the metal fittings of a fire hose, and the metal fittings and hose are washed in the cleaning tank. This means that even if the metal fittings move chaotically in the cleaning tank and collide with each other, they will not be damaged. In the second and third inventions, irregular objects can be washed efficiently and with the same ease as a home washing machine or coin laundry. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0015] Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings. Fig. 1 shows a firefighter's helmet 1, which is an irregular-shaped object to be cleaned in this embodiment. This helmet 1 is not simply a hemispherical shell, but has a complex shape with various convex and concave portions.

[0016] FIG. 2 shows a net-like pouch 2 used in this embodiment. The pouch 2 is made of a cushioning material, such as nylon or polyester. The official water absorption rate of nylon is 4.5%, and that of polyester is 0.4%. The mesh pouch 2 allows a cleaning solution of water with a cleaning agent added thereto to pass through, but allows a helmet or the like inside to remain flexibly stored. One end of a linear fastener 3 is attached along the edge of the upper opening of the mesh pouch 2, and the other end of the fastener 3 is attached to the edge of the lid 4 at the top of the pouch 2. By engaging these fasteners 3, the lid 4 closes the top of the pouch 2, and the contents can be stored in the pouch 2.

[0017] In this embodiment, this small bag 2 is used, and a silicone sheet 5 is placed on the bottom of this small bag 2 as shown in Fig. 2. This silicone sheet 5 is a sheet of sponge formed into a plate shape and impregnated with silicone, and is a sheet with cushioning properties. The sponge is impregnated with silicone in order to increase its strength when agitated by the water flow in the washing tub and to increase its durability. The sponge is a porous soft material with countless fine holes inside.

[0018] Next, as shown in FIG. 3, the helmet 1 is placed upside down on the silicone sheet 5 in the pouch 2.

[0019] Then, as shown in FIG. 4, another silicon sheet 6 is placed on top of the helmet 1 to cover the upper end of the helmet 1 with the silicon sheet 6.

[0020] Next, as shown in FIG. 5, when the zipper 3 is engaged and the opening of the pouch 2 is closed with the lid 4, the helmet 1 is stored in the pouch 2.

[0021] Next, as shown in Fig. 6, a large bag 12 larger than the small bag 2 is prepared. Like the small bag 2, this large bag 12 is made of a mesh-like elastic material and allows cleaning water, which is water with a cleaning solution dissolved in it, to pass through but not objects inside. This large bag 12 also has an opening at its upper end, and the inside of the large bag 12 is closed with the lid 14 by engaging a fastener 13 attached to the edge of this opening with a fastener 13 attached to the edge of a lid 14 that closes the opening.

[0022] Then, a silicone sheet 15 is placed inside the large bag 12. This silicone sheet 15 is made up of five sheets, with one rectangular sheet laid on the bottom of the large bag 12, and four sheets standing along the four stitches of the rectangular sheet, and arranged to surround the bottom sheet. This forms a space made up of the five silicone sheets 15.

[0023] Next, as shown in Figures 7 and 8, the helmet 1 stored in the small pouch 2 shown in Figure 5 is placed in the large bag 12. The small pouch 2 is placed in a space formed by five silicone sheets 15, and a sixth silicone sheet 16 is placed so as to cover the upper part of the space. As a result, the small pouch 2 is surrounded by the six silicone sheets 15, 16. Then, the fastener 13 provided on the edge of the upper opening of the large bag 12 is fastened, the lid 14 is closed, and the helmet 1 stored in the small pouch 2 is sealed in the large bag 12.

[0024] The helmet 1 thus stored in the double mesh bag of the large bag 12 and the small bag 2 together with the silicone sheets 5, 6 and the silicone sheets 15, 16 is loaded into the cleaning tank 20 as shown in Fig. 9. At this time, a plurality of silicone sheets 21 are also loaded into the cleaning tank 20. Thereafter, the opening lid of the cleaning tank 20 is closed, and a cleaning liquid in which a cleaning agent is dissolved in water is introduced into the cleaning tank 20, and the cleaning liquid is stirred to clean the helmet 1. Thereafter, the helmet 1 is taken out of the large bag 12 and the small bag 2, and a rack is placed in a static drying chamber where the helmet is dried at an appropriate temperature, and the helmet 1 is hung on the rack to dry.

[0025] Next, the operation of the cleaning method of the present embodiment configured as described above will be described. Helmets, particularly firefighter helmets, have various protrusions on their shells for the purpose of increasing the strength of the shell. Therefore, if such helmets are loaded directly into a cleaning tank and washed with an agitated water flow of cleaning liquid, the helmets will collide with each other or with the inner surface of the cleaning tank 20, causing scratches on the shell of the helmet, especially on the outer surface. In this embodiment, the helmets are stored in the mesh-like small bag 2 sandwiched between two silicone sheets 5, 6, and the small bag 2 is further stored in the mesh-like large bag 12 surrounded by six silicone sheets 15, 16. Therefore, these silicone sheets function as buffer materials, and even if the helmets 1 collide with each other or with the wall of the cleaning tank, they will not be scratched or deformed. On the other hand, the small bag 2 and the large bag 12 are made of a mesh-like material, so that the cleaning liquid permeates into the bags, and the helmets 1 move randomly in the cleaning liquid due to the agitated flow of the cleaning liquid and come into contact with the cleaning liquid, and the helmets 1 in the bags can be thoroughly washed.

[0026] In this embodiment, a silicone sheet 21 is further inserted into the cleaning tank 20, so that the helmets 1 stored in the small bag 2 and the large bag 12 can be further cushioned from the impact that may occur when they are randomly moved by the agitated flow of the cleaning liquid.

[0027] The silicone sheets 5, 6, 15, 16, 21 are sponges impregnated with silicone, so they are strong and are less likely to wear out even when used for a long period of time. The helmet 1 is merely sandwiched between the silicone sheets 5, 6 in the small bag 2 and is not fixed to the small bag 2. The small bag 2 containing the helmet 1 is also merely surrounded by the silicone sheets 15, 16 in the large bag 12 and is not fixed to the large bag 12. However, the sizes of the small bag 2 and the large bag 12 are set so that there is no gap between the helmet 1, the small bag 2, and the large bag 12, so that the helmet 1 does not move in any direction within the small bag 2 or the large bag 12. On the other hand, if the distance between the helmet 1, the small bag 2, and the large bag 12 is relatively gentle, the helmet 1 will swing freely within the mesh-like small bag 2 while being protected by the silicone sheets 5, 6, and the entire small bag 2 will swing freely within the large bag 12 while being protected by the silicone sheets 15, 16. In this case, the silicone sheets 5, 6, 15, 16 are particularly effective in preventing the helmet 1 from being scratched while allowing the helmet 1 to swing. In any case, the sizes of the small bag 2, the large bag 12 and the silicone sheets can be determined taking into consideration the cleaning effect and the scratch prevention effect. In this way, according to this embodiment, helmets that are irregular objects can be washed in a simple manner similar to that of a home washing machine or a coin laundry, so that a large number of helmets can be washed efficiently and easily with simple operations. The washing program is different from that of a home or coin laundry washing machine, and a dedicated program is prepared for washing helmets and the like.

[0028] Next, another embodiment of the present invention will be described. This embodiment is a cleaning method for cleaning a facepiece 30 instead of a helmet 1. As shown in Fig. 10, the facepiece 30 is a face guard or face shield that a firefighter wears on his face during firefighting activities to ensure breathing at the scene of a fire and to protect the face from fire or obstacles. Unlike a welding facepiece, a firefighter's facepiece has an extremely complicated shape due to the necessity of its use.

[0029] The firefighter's facepiece 30 as a respiratory protective device having such a complex shape can also be washed in the same manner as the above-mentioned helmet 1. First, as shown in Fig. 11, a silicon sheet 5 is placed on the bottom of the small bag 2, and the facepiece 30 is placed on the silicon sheet 5.

[0030] Thereafter, the facepiece is washed with the cleaning liquid in the same steps as those in Figures 4 to 9. In the case of this facepiece 30, as in the case of the helmet 1, the cleaning liquid penetrates the small bag 2 and the large bag 12, which are mesh nets, and directly contacts the facepiece 30 in the cleaning tank 20, and the facepiece 30 is washed by the water flow of the cleaning liquid, and even if the facepiece 30 moves violently in the cleaning tank 20 and hits other facepieces and the wall of the cleaning tank, the facepiece 30 is not scratched.

[0031] Next, another embodiment of the present invention will be described. This embodiment relates to a method for cleaning fire-resistant shoes 40 as shown in Fig. 12. As shown in Fig. 13, the fire-resistant shoes 40 are placed in a mesh bag 41 formed from a mesh net material into a pentagonal bag. The mesh bag 41 has an opening on its maximum side, and a line fastener 42 for opening and closing the opening is attached to the edge of the opening. After the fire-resistant shoes 40 are placed in the mesh bag 41, the fastener 42 is closed to seal the fire-resistant shoes 40 in the mesh bag 41.

[0032] In this state, the fireproof shoes 40 are put into the cleaning tank 30 shown in Fig. 9, and the fireproof shoes are cleaned by the agitated flow of the cleaning liquid. In this embodiment, the cleaning liquid penetrates the mesh bag 41, which is a mesh net, and directly contacts the fireproof shoes 40 in the cleaning tank 20, and the fireproof shoes 40 are cleaned by the water flow of the cleaning liquid. Even if the fireproof shoes 40 move violently in the cleaning tank 20 and collide with other fireproof shoes 40 or the wall of the cleaning tank, the fireproof shoes 40 are not damaged.

[0033] Next, another embodiment of the present invention will be described. This embodiment relates to a method for cleaning a fire hose. As shown in FIG. 14, a fire hose 50 is composed of a hose portion made of a long, rollable material, a fire water discharge end 52 provided at both ends of the hose portion, and a fire water intake end 51. The discharge end 52 is an end for discharging pressurized water to extinguish a fire, and the intake end 51 is an end for taking high-pressure water from a fire hydrant by being connected to the fire hydrant. These discharge end 52 and intake end 51 are cylindrical parts made of metal because they need to maintain their shape with high strength so that they are not deformed by high-pressure water or come off after being attached to the fire hydrant. Therefore, the discharge end 52 and the intake end 51 are rigid and heavy, and therefore are parts that are easily damaged by collision with each other or with the cleaning wall in the cleaning tank.

[0034] For this reason, as shown in Figs. 15 and 16, a protective member 60 is used at the discharge end 52 and the intake end 51 in order to clean the fire hose 50 with an agitated flow of cleaning liquid in the cleaning tank 20. The protective member 60 is made of a cushioning material, like the small bag 2 and the large bag 12, and allows the cleaning liquid, which is water with a cleaning agent added, to pass through, but keeps the contents stored inside flexible. The protective member 60 is bag-shaped with one edge open, and a vertical partition 62 is formed at the open end so as to divide the open end into three. The partition 62 forms three bag sections in the protective member 60. A silicon sheet 61 made of a porous sponge impregnated with silicon is stored in each bag section. A string 65 is attached to the protective member 60 near its center, and a string 66 is attached to the protective member 60 near its opening.

[0035] Then, as shown in Fig. 17, the discharge end 52 and the intake end 51 of the fire hose 50 are aligned, and as shown in Fig. 18, the discharge end 52 and the intake end 51 are connected, and then the protective member 60 is wound around the discharge end 52 and the intake end 51. At this time, the protective member 60 is arranged so that the partition 62 of the protective member 60 is parallel to the longitudinal direction of the discharge end 52 and the intake end 51, and the protective member 60 is wound around the metal parts so that the protective member 60 surrounds the metallic discharge end 52 and the intake end 51. Then, as shown in Fig. 19, the center of the width of the wound protective member 60 is tied with a string 65, and further, the opening of the protective member 60 is tied with a string 66.

[0036] Thereafter, the fire hose 50 prepared as shown in FIG. 20 and the discharge end 52 and the water intake end 51 with the protective member 60 wrapped around them are loaded into the cleaning tank 20 together with a silicone sheet 21 as a cushioning material, and the fire hose 50, as well as the discharge end 52 and the water intake end 51, are cleaned by the agitated flow of cleaning liquid.

[0037] In this embodiment, the fire hose 50 is washed in a state exposed to the cleaning liquid in the cleaning tank 20, and the discharge end 52 and the water intake end 51 are washed in a state surrounded by a silicon sheet 61 and a protective member 60 (mesh net bag). At this time, the cleaning liquid penetrates the mesh bag (protective member 60) and the silicon sheet 61 to reach the outer surfaces of the discharge end 52 and the water intake end 51, so that even if the discharge end 52 and the water intake end 51 are surrounded by the protective member 60 and the silicon sheet 61, they are sufficiently washed by the cleaning liquid. And, since the discharge end 52 and the water intake end 51 are surrounded by the protective member 60 containing the silicon sheet 61 as a cushioning material, the discharge end 52 and the water intake end 51, which are heavy and have high rigidity, are exposed to the agitation flow in the cleaning tank 20 and collide with each other or with the cleaning tank wall, the discharge end 52 and the water intake end 51 are not damaged. [Industrial Applicability]

[0038] According to the present invention, by using cushioning materials such as mesh nets and silicone sheets, irregularly shaped objects such as firefighter helmets and facepieces, which may be scratched or deformed when washed in a washing tank due to collisions, can be washed without scratching or deforming, and multiple irregularly shaped objects can be washed simply and quickly by simply putting the objects into the washing tank in a simple manner similar to washing clothes in a home washing machine or at a coin laundry, which can significantly reduce the incidental work of firefighters in a fire station, for example. The same applies to washing fire boots and fire hoses, and is extremely useful in reducing work that firefighters do not otherwise have to do. [Explanation of symbols]
