Detailed Description
Hereinafter, embodiments of the filter cleaning mechanism and the cloth product drying apparatus using the same according to the present invention will be described.
Lint and the like generated from a cloth product such as a dried cloth product flows into an air blowing path of the cloth product drying apparatus. It is undesirable for lint generated from the cloth product to adhere to the dried cloth product as lint. Further, if a large amount of the lint flows into the blower, the lint causes a failure of the blower. Therefore, a mesh filter for removing lint is provided in the air blowing path.
In the cloth product drying device, the cloth product is dried in a short time by very strong air supply to the cloth product. Therefore, the amount of air blown through the air blowing passage is large, and a large amount of lint adheres to the filter provided in the air blowing passage in a relatively short time depending on the state of the cloth product being dried. When lint adheres to the filter, the blowing efficiency is reduced, and therefore, the drying efficiency is also reduced, and the time required for drying becomes long. Moreover, the drying energy consumption also becomes large. In order to achieve efficient drying of cloth products, lint must often be removed from a filter provided in an air supply passage. Since frequent filter cleaning is required to ensure performance, the filter cleaning operation is a large burden on maintenance of the cloth product drying apparatus.
The present example aims to provide a filter cleaning mechanism that suppresses this heavy burden on maintenance, allows a cloth product drying apparatus to operate efficiently at all times, and prevents lint from scattering by a simple method.
Fig. 1 is a diagram illustrating an example of the basic configuration of the filter cleaning mechanism according to the present invention, and illustrates a state in which the cloth product drying apparatus is attached, detached, and transported, and detached and discarded. A) in the figure shows the installation state of the air blowing path 1. The air duct 1 is shown only partially on the paper, and the cross-sectional line part is a part detachable from the air duct. The wind during blowing flows in the direction of the arrow (from right 7 to left (lower) 8 in the figure). The filter 5 of the air blowing path and a part of the air blowing path on the upstream side thereof are integrally detachable from the air blowing path 1. Fig. 1 shows a cross section of the air duct 1, and although not shown, a cross-sectional line portion is integrally attached to and detached from the air duct wall surface in front of and inside the paper surface of the same length. The detachable portion has an opening on the upstream side of the air blowing path, and is formed in a cup shape including a surface of the filter 5 and a wall surface of the air blowing path. The cleaning mechanism 3 and the portion 4 for housing the cleaning mechanism 3 are provided at one end of the filter 5, and the cleaning mechanism 3 is held in the cleaning mechanism housing portion 4 in a state where the cleaning mechanism is attached to the air blowing path 1 of the fabric drying apparatus and air is blown. The cleaning mechanism of the illustrated embodiment is a general blade cleaning mechanism, and is a method of cleaning lint adhering to a filter by pressing the cleaning mechanism against the filter. The cleaning mechanism housing portion 4 is formed with a deep groove so that the pressure contact of the blade tip is released when the cleaning mechanism, that is, the blade is housed. The cleaning mechanism of the present embodiment discloses the blade cleaning mechanism 3 having a relatively simple structure, but other cleaning methods and mechanisms, such as a brush cleaning mechanism, may be applied.
In the figure, b) schematically shows a state when the filter 5 and the cleaning mechanism 3 are removed from the air blowing path 1 and carried by hand. Since the detachable portion of the embodiment of the present invention is formed in a cup shape, the lint 6 on the filter 5 is hardly peeled off and dropped off, and the lint 6 can be held in the cup by carrying the handle with the opening portion directed upward.
C) in the figure shows a state where the lint 6 is discarded from the filter 5 to the trash box 10 or the like. The cup-shaped attachable and detachable portion 2 of the present embodiment has a structure in which a wall surface 2f attached to one side of the filter and a wall surface 2b to which a blade serving as a cleaning mechanism is attached slide with each other. When cleaning the filter 5, the opening of the cup-shaped detachable portion 2 is directed downward in the dust box 10, and the wall surface 2b (movable portion) on the one side with the blade is slid downward with respect to the wall surface 2f attached to the one side of the filter. Thereby, the blade 3 moves parallel to the surface of the filter 5, scrapes off lint 6 on the filter 5, and discards it to the trash box 10 side. Since the attachable and detachable portion of the present embodiment is surrounded by the filter 5 and the cleaning mechanism 3 and has a cup shape with an opening on one surface, the lint 6 scraped off from the filter 5 by the cleaning mechanism 3 is less likely to scatter and can enter the dust box 10 through the opening.
In the structure of the present embodiment, the filter cleaned by the cleaning mechanism 3 projects to the opposite side of the cleaning mechanism 3, that is, to the outside of the cup shape. The cleaned filter 5 protrudes outward in the cup shape, and thus the surface of the filter 5 is easily accessible. This enables the filter to be easily cleaned even if the cleaning mechanism 3 is insufficiently cleaned.
In addition, the lint 6 and the like sandwiched by the blades 3 can be easily removed. The structure of the present embodiment is also configured such that the wall surface 2f attached to one side of the filter 5 and the wall surface 2b attached with the blade 3 as the cleaning mechanism can be completely separated by sliding the wall surface 2b as the movable portion. If the filter 5 and the blade 3 are configured to be completely separable, cleaning and maintenance of the filter and the blade are very easy. The state of the lint 6 attached to the filter 5 of the laundry drying device is various, and therefore it is almost impossible to ensure that the lint 6 on the filter 5 is completely cleaned by the cleaning mechanism 3 of the present embodiment in all situations. In this sense, the structure of the present embodiment, which is a structure that facilitates cleaning and maintenance of the filter 5 and the blade 3, is a very effective structure.
In the present embodiment, the filter cleaning 3 is manually performed. Needless to say, the setting of the motor, the switch, and the like can be automatically performed, but it is necessary to consider operability, cost, and the like.
Fig. 2 is a diagram illustrating an embodiment of the filter cleaning mechanism of the present invention. The figures show the details of the handling section. When installed in the fabric drying device, air flows in from the side of arrow 7 and is blown out from the filter surface 5 installed on the side and below in the directions of side arrow 8s and lower arrow 8 b. The filter surface 5 in the figure shows a structure in which a filter (translucent) is provided in a lattice structure supporting the filter. As shown in the example structure of fig. 2, the filter surface 5 may be formed on both sides of the cup shape. The cup-shaped attachable and detachable portion is constituted by a side 2b holding the blade as the cleaning mechanism 3 and a side 2f holding the filter 5. The upper part of the blade holding part also serves as a cover part 11 provided on the upper surface of the cloth product drying device, and a detachable handle part 12 is disposed on the upper side.
Fig. 3 is a diagram illustrating an operation method at the time of cleaning with respect to one embodiment of the filter cleaning mechanism of the present invention shown in fig. 2. The cleaning mechanism side wall surface 2b (movable portion) is pulled down from the filter side wall surface 2f above the dust box 10, and the lint 6 attached to the filter 5 is cleaned by the cleaning mechanism and discarded to the dust box 10. At this time, the detachable handle 12 can also be used as the cleaning mechanism operating handle 21 for pulling down the cleaning mechanism side wall surface 2 b.
In the embodiment of the present invention described with reference to fig. 1 to 3, the filter surface is disposed on the surface side adjacent to the cup-shaped opening. In this way, the movement of the blade cleaning mechanism 3 during cleaning of the filter 5 pushes the lint 6 toward the opening portion side, thereby preventing the lint from scattering and stably discharging the lint 6 to the trash box 10. The blade cleaning mechanism 3 described in the present embodiment is a system capable of realizing filter cleaning with a relatively simple structure.
Fig. 4 is a diagram for explaining an embodiment of a cloth product drying apparatus using the filter cleaning mechanism of the present invention. A cloth product drying apparatus using the filter cleaning mechanism of the present invention will be described. The apparatus shown in the figure is a horizontal rotary drum type drying apparatus which is widely used. The cloth product is fed into the rotary drum through a door 16 provided on the front surface of the apparatus. The rotary drum 15 is rotated by a motor 17 directly connected thereto, thereby agitating the cloth product and drying the cloth product by air sent from the blower fan 14. The air sent to the fabric product becomes warm air dried by a heater or the like not shown. The dry air circulates through an air supply passage 1 provided in the apparatus in accordance with the arrow.
A washing and drying machine having a washing function in addition to a drying function of a cloth product basically has the same configuration, and includes a water suction port 19 for supplying water to a rotary drum and a water discharge port 18 for discharging water, and performs washing by stirring a detergent and the cloth product together. The device of fig. 3 is a schematic view of a washing and drying machine having a washing function, and therefore, a water suction port 19 and a water discharge port 18 are also shown.
The filter cleaning mechanism of the present embodiment is disposed above the cloth product drying apparatus and upstream of the blower fan 14. In consideration of the maintainability of the filter 5, the filter cleaning mechanism of the present embodiment is preferably disposed at the upper portion of the illustrated cloth product drying apparatus. In particular, in an apparatus requiring water retention in the rotary drum 15, such as a washing/drying machine, the blower fan 14, the filter 5, and the cleaning mechanism 3 are preferably located at high positions not affected by water.
In the cloth drying apparatus of the embodiment of fig. 4, one fixed filter 13 is further disposed between the filter cleaning mechanism and the blower fan of the embodiment. In fact, although it is considered that the lint 6 flowing in the air blowing path can be substantially collected by the filter 5 of the filter cleaning mechanism of the present embodiment, the filter 5 may be damaged by chance in the mechanism for attaching and detaching the cleaning filter 5 as in the present embodiment. Further, in the structure in which a part of the air blowing path is attached and detached as in the present embodiment, there is a possibility that air blowing is directly performed in a state in which the attachment and detachment portion is attached and detached. In fact, although it is necessary to provide the detachable detection and control of the air blowing path so that the air blowing operation cannot be performed with the detachable portion detached, the risk of detection errors and erroneous control operations must be considered. Therefore, the embodiment of the cloth product drying apparatus of the present invention is based on the configuration in which the fixed filter 13 is provided between the filter cleaning mechanism and the blower 14.
In reality, since the air blowing operation is performed by the filter cleaning mechanism 2 of the present embodiment, the fixed filter 13 does not need to be cleaned, and a large burden on maintenance is not imposed. However, if the fixed filter 13 is located in the air blowing path, lint 6 and the like leaking from the upstream filter 5 may be deposited and obstruct the air blowing. Therefore, in the cloth product drying apparatus of the present embodiment, the fixed filter 13 is disposed in the vicinity of the filter cleaning mechanism of the present embodiment, and it is considered that the cleaning is easily performed from the cup-shaped attachable and detachable portion 2 of the filter cleaning mechanism. In fact, when the filter cleaning mechanism of the present embodiment is applied to a cloth product drying apparatus or the like, it is important to take such consideration into consideration.
In the cloth product drying apparatus of the embodiment of fig. 4, a lid 11 integrated with the outer package of the frame body is provided above the cup-shaped attaching and detaching portion 2. The cup-shaped attachment/detachment portion needs to be fitted in a cup shape in which the lid portion 11 of the filter side 2f and the vane side 2b are assembled. In the application of the cloth product drying apparatus, it is also considered to provide a sensor or the like on the cloth product drying apparatus side for preventing the filter side from being left assembled by chance. Since a general mechanical switch or optical sensor can be used as a mechanism for detecting a sensor or the like, detailed description thereof is omitted. In addition, since the cleaning mechanism 3 must be located at the standby position 4 when the cleaning mechanism is assembled to the cloth product drying apparatus, the cleaning mechanism does not adversely affect the air flow when the cleaning mechanism is mounted to the cloth product drying apparatus.
Fig. 5 is a diagram for explaining an example of the mounting arrangement of the filter cleaning mechanism according to the present invention. As described in the embodiment of fig. 4, the upper part of the apparatus is most preferable when the filter cleaning mechanism of the present embodiment is mounted on the cloth product drying apparatus. In the cloth product drying apparatus, it is necessary to be able to dry as many cloth products as possible in a limited apparatus size, and therefore, it is preferable to mount and arrange the rotary drum 15 as large as possible. In the case where a large rotary drum 15 is disposed in a substantially box-shaped device, the remaining installation space is a space near the motor 17 on the back side of the device and a space on the obliquely upper side of the cylindrical rotary drum 15 on the side of the device. In this case, the arrangement of the air duct 1 in front of and behind the cleaning device according to the present invention is effective in mounting in consideration of downsizing of the device, with the arrangement substantially shown in fig. 4.
First, a space on the obliquely upper apparatus side surface side of the cylindrical rotary drum 15 is used as a mounting portion of the blower fan 14 for sending air to the rotary drum 15. A vertical duct 1 is disposed on the back surface of the apparatus as a blowing path for blowing the air discharged from the drying drum 15 to a blowing fan 14 above the apparatus. In the mounting arrangement shown in fig. 4, the filter cleaning mechanism of the present embodiment is preferably mounted at a position (region 12 enclosed by a broken line) where the air duct is bent at a right angle.
The filter attaching/detaching portion with the cleaning mechanism of the present embodiment described in fig. 1 to 3 has a structure in which the filter is disposed on the side surface of the opening portion, and therefore, can be easily disposed in the broken line portion 23 in fig. 4.
As described above, the filter cleaning mechanism of the present embodiment is configured in the cup shape, so that when the filter is removed from the cloth product drying apparatus and conveyed, even when the cleaning mechanism cleans the filter on the dust box 10, scattering of lint attached to the filter can be prevented. However, needless to say, lint falling off from the filter falls outside the cup when the opening of the cup is directed downward during transportation. In order to further reliably prevent the scattering of lint from the filter 5 removed from the cloth product drying apparatus, it is effective to provide a cover for closing the cup-shaped opening. The cover provided in the cup-shaped opening is configured to open in conjunction with the operating rod of the cleaning mechanism, thereby improving the operability during cleaning. Further, by closing the cover when the fabric drying apparatus is attached, the malfunction can be eliminated and the operability can be improved. The structure for opening the cover when returning the filter cleaning mechanism to the cloth product drying apparatus can be relatively easily realized by assembling the shape of the guide portion, and the details thereof are omitted.
In addition, in the case of a structure in which a lid capable of locking the cup-shaped opening portion is provided according to the operation of attaching and detaching the cup-shaped filter cleaning mechanism portion from the cloth product drying apparatus, even if the waste falls from the filter, there is no fear that the waste falls out of the cup shape. When such a cover is provided, it is not necessary to move the cleaning mechanism above the dustbin. In the case of adopting a structure provided with a cover for such a cup shape, a method of interlocking the operation of the cleaning mechanism with the attachment/detachment operation of the cloth product drying apparatus is also conceivable. With this configuration, the lint can be discarded by opening the lid of the dustbin, and the operability is further improved. However, it is difficult to realize the cleaning by a simple structure in which a cleaning mechanism is provided in a part of the wall surface and cleaning is performed by sliding as in the embodiment shown in fig. 1 to 3. In order to operate the cleaning mechanism by the attaching and detaching operation of the cloth product drying apparatus, an independent cleaning mechanism needs to be arranged. Therefore, compared to the embodiment configuration of the present invention shown in fig. 1 to 3, there is a weak point that the configuration easily becomes complicated.
Fig. 6 is a diagram illustrating a structure of a filter cleaning mechanism according to an embodiment of the present invention, which includes a movable unit capable of rotating. A) in the figure shows the installation state of the air blowing path 1. The air duct 1 is shown only partially in the drawing, and the cross-sectional line part is a part detachable from the air duct. The wind during blowing flows in the direction of the arrow (from right 7 to left 8 in the figure). The filter 5 of the air supply passage and a part of the air supply passage on the upstream side thereof are integrally detachable. Since fig. 1 shows a cross section of the air duct 1, a cross-sectional line portion is integrally attached to and detached from the air duct wall surface in front of and inside the paper surface of the same length, although not shown. The detachable portion has an opening on the windward side (lower side in the figure) of the air blowing path, and is formed in a cup shape including a surface of the filter 5 and a wall surface of the air blowing path. The cleaning mechanism 3 and the portion 4 for housing the cleaning mechanism 3 are provided at one end of the filter 5, and the cleaning mechanism 3 is held in the cleaning mechanism housing portion 4 in a state where the cleaning mechanism is attached to the air blowing path 1 of the fabric drying apparatus and air is blown. The cleaning mechanism of the illustrated embodiment is a general blade cleaning mechanism, and is a method of cleaning lint adhering to a filter by pressing the cleaning mechanism against the filter. A deep groove is formed in the cleaning mechanism housing portion 4 so that the pressure contact of the blade tip is released when the cleaning mechanism (blade) is housed. The cleaning mechanism of the present embodiment discloses the blade cleaning mechanism 3 having a relatively simple structure, but may be used for other cleaning mechanisms and systems, such as a brush cleaning mechanism.
The same as described above applies to the treatment when the cloth product is detached from the cloth product drying apparatus and carried by hand to a trash, in which the treatment is carried by hand with the opening of the cup-shaped attaching and detaching portion 2 directed upward, and the lint 6 can be safely held in the cup-shaped attaching and detaching portion 2, as in b) of fig. 1.
B) in fig. 6 shows a state where the lint 6 is discarded from the filter 5 to the trash 10 or the like. The cup-shaped attachable and detachable portion 2 of the present embodiment has a structure in which a wall surface 2f attached to one side of the filter and a wall surface 2b to which a blade as a cleaning mechanism is attached are rotated about a rotational movable shaft 22. When cleaning the filter 5, the opening of the cup-shaped attaching and detaching portion 2 is directed downward above the dust box 10, and the cleaning mechanism operation handle portion 21 attached to the wall surface on one side of the filter is grasped and rotated by about 90 degrees. The filter 5 is rotated while being rubbed against the blade 3, thereby scraping lint from the filter, and the lint falls and is discarded to the dust box 10. The attaching and detaching portion 2 of the present invention is formed in a cup shape surrounding the filter 5 and the cleaning mechanism 3, and therefore, lint falling during conveyance of the attaching and detaching portion is prevented, and the lint 6 scraped off from the filter 5 by the cleaning mechanism 3 is less likely to scatter and can enter the dust box 10 from the opening.
Further, in the structure of the present embodiment, the filter cleaned by the cleaning mechanism 3 protrudes toward the outside of the cup shape, which is the opposite side of the cleaning mechanism 3. The cleaned filter 5 protrudes outward in the cup shape, and thus the surface of the filter 5 is easily accessible. This enables the filter to be easily cleaned even if the cleaning mechanism 3 is insufficiently cleaned. Further, the removal of lint 6 and the like sandwiched by the blade 3 can be performed from the opening surface after the movement of the filter, and the structure is easy to perform these operations.
The structure of the present embodiment is configured such that the wall surface 2f attached to one side of the filter 5 and the wall surface 2b attached with the blade 3 as the cleaning mechanism, which are connected by the rotation movable portion, cannot be separated. By adopting the structure that can not be separated, the filter 5 can be prevented from being forgotten to be installed when the clothes drying device is installed. By adopting the inseparable structure of the present embodiment, it is not necessary to provide the sensor or the like for preventing the filter from being erroneously mounted on the cloth product drying apparatus. This structure can be automatically performed by providing a motor, a switch, or the like, but similarly to the above, it is necessary to consider operability, cost, and the like.
As described above, by using the filter cleaning mechanism of the present embodiment and the cloth product drying apparatus using the same, filter cleaning in which scattering of lint does not occur can be realized in a simple manner. Further, a filter cleaning mechanism and a cloth product drying apparatus using the same are provided, which can easily perform cleaning work of a filter surface and a blade even when cleaning is not sufficient only in a normal cleaning operation.
