Description

[Technical Field]

[0001] The present invention relates to a hanging-type cleaning tool for a three-dimensional clothes dryer, and more particularly to a hanging-type cleaning tool used to remove dust adhering to the inner wall surfaces of a tunnel-shaped passage in a three-dimensional clothes dryer in which laundry, hung on hangers, is transported through the passage and dried with hot air. [Background technology]

[0002] A known example of this type of three-dimensional clothes dryer is described in Patent Document 1. In this conventional machine, clothes are hung on hangers, which are then hung on a chain conveyor and passed through a tunnel-like passage, and steam is blown onto the clothes as the hangers move through the passage, steaming them and then blowing hot air onto them to finish drying them.

[0003] When hot air or the like is blown onto the clothes from above in this type of three-dimensional clothes dryer, the hanging clothes sway back and forth in a large wave-like motion, hitting the inner wall surfaces of the passageway as they are transported. Therefore, when this type of dryer is used, dust such as lint is generated from the clothes, and this type of dust adheres to the inner wall surface of the passage, inevitably causing the inner wall surface of the passage to become dirty.

[0004] If this type of dirt is left unattended, it can have a negative effect on the finish of the clothes, so in the past, in order to clean this type of dirt, it was common to insert a mop or other cleaning tool into the corridor from the entrance side and use this type of cleaning tool to periodically wipe down the inner walls of the corridor. Therefore, conventionally, this type of cleaning requires time, effort, and cost, which in turn reduces the efficiency of the work of drying and finishing clothes.

[0005] [Patent Document 1] Japanese Utility Model Application Publication No. 6-75395 Summary of the Invention [Problem to be solved by the invention]

[0006] The present invention has been proposed in view of the above problems of the prior art. Therefore, the technical problem to be solved by this invention is to provide a hanging-type cleaning tool for a three-dimensional clothes dryer, which transports clothes hanging on hangers through a passageway to dry the clothes, and which is designed to reduce and save the time, effort and cost required to clean dust such as lint that adheres to the inner walls of the passageway, thereby improving the work efficiency of drying the clothes. [Means for solving the problem]

[0007] In order to solve the above problems, the present invention employs the following technical means. That is, as shown in FIG. 1 etc., the present invention relates to a cleaning tool 5 used to clean the inner wall surface 3a of the passage 3 of a three-dimensional clothes dryer 4 in which laundry clothes 1 hung on hangers 2 are transported through a tunnel-shaped passage 3, hot air is blown onto the clothes 1 from above, and the clothes 1 are dried and finished by the hot air, and the cleaning tool 5 is characterized in that it is composed of a wiping tool 6 that is transported in a hanging state within the passage 3, expands due to the hot air, and is pressed against the inner wall surface 3a of the passage 3 to wipe away dust adhering to the inner wall surface 3a, and a hanging tool 7 for hanging the wiping tool 6 within the passage 3, the wiping tool 6 being non-permeable and formed in a cylindrical shape with a hot air outlet 6d smaller than the hot air inlet 6c, and the hanging tool 7 is formed so as to be freely attached and detached to the wiping tool 6 with the hot air inlet 6c of the wiping tool 6 open.

[0008] In the present invention, the wiper 6 is non-permeable and cylindrical with a hot air outlet 6d smaller than the hot air inlet 6c. As a result, the hot air stagnates inside, increasing the contact friction with the inner wall surface 3a of the passage 3, and the wiper is firmly pressed against the inner wall surface 3a. This prevents the lower part from flowing backward and being carried in an inclined position when towed, and allows the wiper 6 to thoroughly clean the dirt on the inner wall surface 3a.

[0009] In an embodiment that can obtain this type of effect, the wiping tool 6 is formed in a tapered shape from the hot air inlet 6c toward the hot air outlet 6d, as shown in FIG. 1B and other figures.

[0010] Furthermore, in the cleaning tool 5 of the present invention, a partition 6f is provided in the body portion 6e of the wiping tool 6, extending in the longitudinal direction of the wiping tool 6 and dividing the body portion 6e into two equal parts, and it is preferable that this partition 6f forms adjacent parallel hot air flow paths in the body portion 6e.

[0011] This is because in this case, the body portion 6e of the wiper 6 is pressed firmly against the inner wall surface 3a by the bulges of the two adjacent parallel flow paths, allowing dirt to be wiped away in two stages, thereby making it possible to clean the inner wall surface 3a even more thoroughly. [Effects of the Invention]

[0012] The cleaning tool of the present invention is formed of a wiping tool that is transported in a suspended state within the tunnel-shaped passageway, expands with hot air and is pressed against the inner wall surface of the passageway to wipe away dust adhering to the inner wall surface, and a hanging tool for hanging the wiping tool within the passageway, the wiping tool being non-air permeable and formed in a cylindrical shape with a hot air outlet smaller than the hot air inlet, and the hanging tool being formed so as to be detachable from the wiping tool with the hot air inlet of the wiping tool left open.

[0013] Therefore, in the present invention, the wiper expands with hot air and is carried while being firmly pressed against the inner wall surface of the passage with large contact friction, so that dust such as lint adhering to the inner wall surface of the passage can be wiped off simply, easily and reliably. As a result, the time and effort required for cleaning the inner wall surfaces of such passages can be reduced and the cost can be reduced, and the efficiency of the work of drying and finishing clothes can be improved.

[0015] A preferred embodiment of the present invention will now be described with reference to the accompanying drawings. As shown in FIG. 1, the present invention relates to a cleaning tool 5 used to clean the inner wall surface 3a of the passage 3 of a three-dimensional clothes dryer 4, which transports laundry (clothes 1) hanging on hangers 2 through a tunnel-shaped passage 3 and blows hot air onto the clothes 1 from above to dry and finish the clothes 1.

[0016] The three-dimensional clothes dryer 4 is equipped with a radiator as a source of hot air, a blower that blows hot air onto the clothes 1 from above, and a hot air circulation path that guides and circulates the hot air from top to bottom.

[0017] As described above, the present invention relates to a cleaning tool 5 used to clean the inner wall surface 3a of the passage 3 of such a three-dimensional clothes dryer 4. As shown in Fig. 1B etc., the cleaning tool 5 of the present invention is transported in a suspended state within the passage 3, expands due to the hot air, and is pressed against the inner wall surface 3a of the passage 3 to wipe away dust adhering to the inner wall surface 3a, and is formed of a wiper 6 and a hanger 7 for hanging the wiper 6 within the passage 3.

[0018] The wiping tool 6 is non-permeable and cylindrical with a hot air outlet 6d smaller than the hot air inlet 6c. In this embodiment, the wiping tool 6 is made of ultrafine synthetic fiber cloth 6a (see FIG. 2, etc.), the inside of which is covered with a non-permeable sheet material 6b, and is cylindrical, tapering from the hot air inlet 6c to the outlet 6d. The length and width of the wiping tool 6 can be selected appropriately depending on the height and length of the passage 3, etc.

[0019] In addition, the wiping tool 6 of this embodiment has a partition 6f in its body portion 6e that extends in the longitudinal direction of the wiping tool 6 and divides the body portion 6e into two equal parts, and this partition 6f forms hot air flow paths in the body portion 6e in a parallel, adjacent manner.

[0020] The partition 6f is realized by sewing the opposing front and rear surfaces together in a straight line, for example by sewing. The length of the partition 6f is appropriately selected depending on the length of the wiping tool 6. In this embodiment, as shown in Fig. 8, the wiping tool 6 is provided with a plurality of attachment strings 6g attached at one end to each other at appropriate positions around the hot air inlet 6c.

[0021] The suspender 7 is made of metal, heat-resistant resin, or the like, and is formed in a hanger shape as shown in Fig. 5. In this embodiment, as shown in the figure, the suspender 7 has a hook 7b formed in the center of a bar 7a extending in the left-right direction, and a plurality of auxiliary bars 7c extending in the front-rear direction are fixed to the left and right positions of the bar 7a, sandwiching the hook 7b, so as to be perpendicular to the longitudinal direction of the bar 7a.

[0022] In this embodiment, a total of four auxiliary bars 7c are formed with the same length, and round holes 7d are formed in the tip end of each auxiliary bar 7c and at both ends of the bar 7a.

[0023] As shown in Fig. 8, the wiping tool 6 is detachably attached to the hanging tool 7 with the hot air inlet 6c open by passing a string 6g through the round hole 7d and tying it. Then, the hanging tool 7 with the wiping tool 6 attached is hung on an endless chain conveyor 8 as shown in Figs. 1B and 9.

[0024] Next, the operation of the present invention in this embodiment will be described. First, as shown in Fig. 8, the worker passes the string 6g of the wiping tool 6 through the round hole 7d at the corresponding position of the hanging tool 7, and ties the wiping tool 6 to the hanging tool 7. At this time, the hot air inlet 6c of the wiping tool 6 is opened and expanded into an oval shape when viewed from above.

[0025] Next, the worker hooks the hook 7b of the hanging tool 7 onto the chain conveyor 8, and hangs the wiping tool 6 from the chain conveyor 8. As a result, the wiping tool 6 is arranged in a suspended state within the passage 3, as shown in Figure 9. Then, the worker turns on the operation switch of the three-dimensional clothes dryer 4.

[0026] 1B, the chain conveyor 8 is driven to move the wiping tool 6 as shown by the arrows, and hot air is blown onto the wiping tool 6 from top to bottom as shown by the arrows in the same figure. As described above, the wiping tool 6 has a hot air inlet 6c and outlet 6d, and is formed in a cylindrical shape with no air permeability, with the hot air outlet 6d being smaller than the hot air inlet 6c. Therefore, when hot air is blown onto the wiping tool 6 from above, the wiping tool 6 expands and is pressed against the inner wall surface 3a of the passage 3, causing it to be moved.

[0027] In this case, the wiping tool 6 is tapered in this embodiment, so that the upper part of the wiping tool 6 is pressed against the inner wall surface 3a of the passage 3 over a wide area and comes into close contact with it, as shown in FIG.

[0028] 3, the body portion 6e of the wiper 6 has two parallel hot air flow paths that are adjacent to each other and separated by a partition 6f. Therefore, each flow path of the body portion 6e expands with the hot air and is pressed independently against the inner wall surface 3a of the passage 3. As a result, the contact friction between the inner wall surface 3a and the body portion 6e increases, allowing dirt on the inner wall surface 3a to be thoroughly wiped away in two stages.

[0029] Furthermore, the wiping tool 6 is tapered (see Fig. 1B and Fig. 4). Therefore, the amount of hot air flowing out from the lower part of the wiping tool 6 is reduced, and the hot air tends to stagnate there. As a result, the lower part of the wiping tool 6 is pressed strongly against the inner wall surface 3a.

[0030] As a result, when the chain conveyor 8 is driven and the wiping tool 6 is pulled, the wiping tool 6 does not tilt or flap; in other words, the wiping tool 6 is transported while maintaining a nearly vertical posture without assuming an inclined posture with the lower part tilted backward. Therefore, according to the present invention, dust adhering to the inner wall surface 3a can be reliably removed with the entire surface of the wiping tool 6, and the inner wall surface 3a can be thoroughly cleaned. The wiping tool 6 is replaced as needed depending on the degree of dirt.

[0031] In the above example, the wiper 6 is tapered, but the present invention is not limited to this. That is, the wiper 6 may be formed so that when it expands with hot air and is pressed against the inner wall surface 3a of the passage 3, the contact friction at the bottom is greater than that at the top.

[0032] In the embodiment shown in Fig. 10, the wiping tool 6 is formed with the same width in the vertical direction (longitudinal direction), and the hot air outlet 6d is formed with multiple small holes, so that the outlet 6d has a smaller area than the inlet 6c. In the embodiment shown in Fig. 11, the lower part of the wiping tool 6 is narrowed, so that the outlet 6d is smaller than the inlet 6c.

[0033] Furthermore, the shape of the hanger 7 is arbitrary as long as it can widen the hot air inlet 6c of the wiping tool 6. The embodiment shown in Fig. 12 is an example in which the attachment portion 7e for widening the inlet 6c of the wiping tool 6 is formed in a ring shape. Furthermore, in the case of the present invention, the wiping tool 6 is not limited to being attached to the hanger 7 by a string 6g, and may be attached by other well-known attachment and detachment means.
