Embodiments for Carrying Out the Invention

[0023] Hereinafter, embodiments of the present invention will be described with reference to the drawings. Note that the present invention is not limited by this embodiment.

[0024] FIG. 1(a) is a perspective view showing a dryer in which a filter cleaning device according to the present invention is installed, and FIG. 1(b) is a cross-sectional view showing the internal structure of the dryer. The dryer according to the present invention will be described below with reference to these figures.

[0025] The dryer 40 according to the present invention includes a dryer main body 30 having a door 30a on the front surface, and hot air generated by a blowing means (fan) 33 and a heating means 32 is circulated and supplied through ventilation ducts 31a, 31b, 31c into a rotary drum 30b rotatably disposed in a tank 30d for accommodating clothes or the like, so that the clothes can be dried. Further, the filter cleaning device 10 according to the present invention is detachably installed in the air passage on the exhaust side from the tank 30d of the ventilation ducts 31a, 31b, 31c. In addition, the filter cleaning device 10 is configured to be able to be taken in and out from an outlet 30e formed on the upper surface portion of the dryer main body 30. Note that the outlet 30e can also be formed on the front surface portion of the dryer main body 30.

[0026] Reference numeral 30c is a motor for rotating the rotary drum 30b, and this motor 30c rotates the rotary drum 30b during various processes such as a drying process, a washing process, a rinsing process, and a dehydration process. As an example, a heat exchanger can be used for the heating means 32. Note that various methods such as a heat pump type and a heater type can be adopted as the method of the heat exchanger. Further, although the dryer 40 is of a drum type, it is not limited thereto, and for example, various methods such as a vertical type can be adopted.

[0027] FIG. 2(a) is a perspective view showing a filter cleaning device according to the present invention, and FIG. 2(b) is a perspective view showing the filter cleaning device according to the present invention with the lid body opened. FIG. 3(a) is a perspective view showing the operation of the filter cleaning device when mounted on a dryer, with the cleaning body in the initial position. FIGS. 3(b) and (c) are perspective views showing the operation of the filter cleaning device when removed from the dryer. FIG. 3(b) shows the state where the cleaning body is slightly moved, and FIG. 3(c) shows the state where the cleaning body is moved to the end of the forward path. FIGS. 4(a) to (c) are perspective views of the states corresponding to FIGS. 3(a) to (c) viewed from the lower side. In FIGS. 3 and 4, the filter panel and the lid body are omitted. The details of the filter cleaning device according to the present invention will be described below with reference to these figures.

[0028] A filter cleaning device 10 according to the present invention includes a main body case 1 that is detachably attached to a ventilation duct, a filter panel 2 provided on the upper surface of the main body case 1 in a state where the main body case 1 is attached to the ventilation duct and having a handle part 2a that can be gripped by a user, an arc-shaped filter body 3 provided inside the main body case 1 for collecting dust, a ventilation path 4 provided upstream of the filter body 3, a rotating shaft 5 installed in the ventilation path 4, a cleaning body 6 that is provided on the rotating shaft 5 and rotatably abuts against the filter body 3 to remove or discharge dust attached to the filter body 3, and a cleaning mechanism 7 that moves the cleaning body 6 in conjunction with the rotating shaft 5.

[0029] The lid body 13 and the bottom plate 1a constitute the main body case 1. The lid body 13 is formed with ventilation holes 13a and is installed so as to be freely opened and closed by a hinge 13b connected to the bottom plate 1a. Inside the lid body 13, a dust box 13c for accommodating dust removed from the filter body 3 is formed.

[0030] Further, the cleaning mechanism 7 includes a rack gear member 7a that meshes with a pinion gear 5a formed at one end of the rotation shaft 5 to convert the rotation of the rotation shaft 5 into a radial movement with respect to the axial direction of the rotation shaft 5, a connecting means A8a that is partially interlocked with the rack gear member 7a and moves the rack gear member 7a in the forward path direction, and a connecting means B8b that moves the rack gear member 7a in the return path direction. The pressing member 8 includes a pressing member 8. In a state where the filter cleaning device 10 is removed from the ventilation duct, the rack gear member 7a is interlocked with the reciprocating movement of the pressing member 8 in the reciprocating direction. In a state where the filter cleaning device 10 is attached to the ventilation duct, the pressing member 8 is not interlocked with the reciprocating movement of the rack gear member 7a in the reciprocating direction. A gear 5b is formed at the other end of the rotation shaft 5. This gear 5b meshes with the gear on the drive source side of the dryer body, and the rotation of the rotation shaft 5 during automatic cleaning is controlled by a control device installed on the dryer body side. As a result, when discarding dust, it is possible to easily discharge the dust without soiling the user's hands by operating the pressing member. During automatic cleaning, excellent operability and dust removal performance can be exhibited while ensuring safety.

[0031] Note that the filter cleaning device 10 according to the present invention is mainly used by being detachably attached to the ventilation duct of the dryer, but is not limited thereto, and can be used by being attached to various devices equipped with a ventilation duct.

[0032] Further, the connecting means A8a converts the rotational movement of the pressing member 8 opening outward into a linear movement of the rack gear member 7a in the forward path direction, and the connecting means B8b converts the rotational movement of the pressing member 8 closing inward into a linear movement of the rack gear member 7a in the return path direction. As a result, the pressing member 8 rotates outward from the initial position, closes inward, and returns to the initial position. During this period, the cleaning body 6 can reciprocally clean the filter body 3, so that the dust removal performance can be improved.

[0033] The connecting means A8a is fixed such that a protrusion 8c formed at one end of the pressing member 8 is fitted into a guide groove 7b formed at one end of the rack gear member 7a and is slidable in the longitudinal direction of the guide groove 7b. In a state where the filter cleaning device 10 is mounted on the ventilation duct, the protrusion 8c is not pressed when the rack gear member 7a moves in the reciprocating direction. As a result, during automatic cleaning, the pressing member does not rotate, enabling a simple structure, ensuring safety, and allowing the dust removal performance to be exhibited.

[0034] FIG. 5(a) is a perspective view showing the operation of the filter cleaning device in a state of being mounted on the dryer, showing a state where the cleaning body is moved to the middle of the filter body. FIG. 5(b) is a perspective view corresponding to FIG. 5(a) viewed from the lower side. In FIG. 5, the filter panel and the lid body are omitted. As shown in these figures, the connecting means B8b is a clamp member 8b that is connected to the pressing member 8 via a connecting shaft 12a and moves by the rotation of the movable shaft 9c. The clamp member 8b has a protruding piece 9d. In a state where the pressing member 8 is closed inward, the protruding piece 9d is pressed, and the clamp member 8b is lifted upward with the movable shaft 9c as a fulcrum. That is, since the clamp member 8b is in a state of moving to a position where it does not interfere with the movable region of the rack gear member 7a, the pressing member 8 does not move in conjunction with the movement of the rack gear member 7a. On the other hand, when the filter cleaning device 10 is removed from the dryer and the pressing member 8 is opened outward (see FIGS. 3(c) and 4(c)), the protruding piece 9d is released, and the clamp member 8b is configured to move to a position where it interferes with the movable region of the rack gear member 7a. Therefore, the rack gear member 7a moves in conjunction with the movement of the pressing member 8. As a result, it is possible to achieve both safety during automatic cleaning and improved operability when operating the pressing member 8 with a simple structure.

[0035] Fig. 6(a) is a plan view showing the operation of the filter cleaning device when attached to the dryer, and Fig. 6(b) is a plan view showing the operation of the filter cleaning device when removed from the dryer. Further, Fig. 7(a) is a cross-sectional view taken along the line C-C of Fig. 6(a), and Fig. 7(b) is a cross-sectional view taken along the line B-B of Fig. 6(a). As shown in these figures, the connecting means A8a has a support member 14 that contacts the rack gear member 7a and supports movement in the reciprocating direction. The support member 14 is configured to contact at least two or more surfaces including the surface facing the pinion gear 5a with the rack gear member 7a sandwiched therebetween. In Fig. 7(b), the support member 14 contacts the rack gear member 7a at three surfaces. Thereby, the support member 14 can surely bring the rack gear member 7a into contact with the pinion gear 5a. With a simple structure, the operability during the operation of the pressing member 8 can be improved, and the rotation of the cleaning body during automatic cleaning can be smoothly performed.

[0036] Also, when the filter cleaning device 10 is attached to the dryer body, the filter panel 2 is fixed at a position closing the take-out port 30e, and the pressing member 8 is on the side of the filter panel 2 and is arranged inside the take-out port 30e when viewed from the vertical side. When the filter cleaning device 10 is removed from the ventilation duct, the pressing member 8 is reciprocally movable to the side of the filter panel 2, and when the filter cleaning device 10 is attached to the ventilation duct, the pressing member 8 is configured not to be reciprocally movable to the side. Thereby, it is possible to prevent the pressing member 8 from rotating when the filter cleaning device 10 is attached to the dryer body 30, ensure safety during automatic cleaning, and reduce the accommodation space of the filter cleaning device 10 in the dryer body 30.

[0037] Further, the outer surface of the filter panel 2 is formed in a substantially rectangular shape, and the pressing member 8 has a knob portion 8d for gripping during opening and closing operations at one end. The knob portion 8d is a part of the outer surface of the filter panel 2 and is arranged near one of the four corners. Thereby, the filter cleaning device 10 can be made compact and the appearance can be improved.

[0038] Although not shown in the drawings, one end of the pressing member has a knob portion for gripping during the opening and closing operation. In a state where the filter cleaning device is attached to the ventilation duct, the knob portion is disposed on the inner surface side of the filter panel and may be configured so as not to be operable from the outside. This can improve the safety during the automatic cleaning of the filter cleaning device.

[0039] Also, as shown in FIG. 6(a), the pressing member 8 is rotatably connected to the filter panel 2 or the main body case 1 by a fixed shaft 11. The pressing member 8 has a knob portion 8d for gripping during the opening and closing operation at one end, and between the fixed shaft 11 and the knob portion 8d, there is a branch portion 12 connected via a rack gear member 7a and a connecting shaft 12a. The relationship between the linear distance A from the fixed shaft 11 to the knob portion 8d and the linear distance B from the fixed shaft 11 to the base of the branch portion 12 is such that the linear distance B is approximately 1 / 2 or less of the linear distance A. Thus, by utilizing the principle of the lever, the force of the user's finger can be reduced, and the operability during the operation of the pressing member 8 can be further improved.
