Description

Technical Field

[0001] The present invention relates to a filter cleaning device provided in a vehicle air conditioning system such as an automobile. Background Art

[0002] In a vehicle air conditioning device, when external air is taken in and conditioned and then sent indoors, the external air is purified by a filter and then supplied indoors. Since dust contained in the external air accumulates on the filter and causes clogging, the filter needs to be cleaned. In addition, when the internal air is circulated indoors, a filter is provided to purify dust generated indoors, and the dust accumulated on the filter needs to be cleaned. In addition, an invention for automating the cleaning of the filter is known in the past (Patent Document 1).

[0003] The vehicle air conditioning device described in Patent Document 1 is configured such that, if the glove box is opened to store or take out small items, a cable pulls the brush box, and a scraper member removes foreign matter on the air filter and discharges it from the exhaust duct. Also, if the glove box is closed, a tension coil spring is used to return the brush box and the scraper member to their original positions.

[0004] Patent Document 1: Japanese Patent Application Publication No. 2007-216712

[0005] The vehicle air conditioning device described in Patent Document 1 does not require a motor to drive the scraping member, nor does it require wiring to supply power to the motor, so it is a device that can achieve a reduction in manufacturing cost. However, there is a problem that dust remains accumulated on the filter and becomes clogged when the glove box is not opened or closed. Summary of the invention

[0006] The present invention is used to solve the above-mentioned conventional problems, and its object is to provide a filter cleaning device which does not require a motor or electrical wiring, thereby reducing the manufacturing cost and allowing the filter to be cleaned frequently every time a vehicle is used.

[0007] In order to solve the above-mentioned existing problems, the filter cleaning device of the invention of method 1 is arranged in a vehicle air conditioning device, and the filter cleaning device comprises: a filter; a cleaning piece abutting against the filter to remove dust attached to the surface of the filter; and a movable mechanism connected to the cleaning piece and controlling the movement of the cleaning piece while maintaining the distance between the cleaning piece and the filter substantially constant, and the movable mechanism utilizes the inertial force generated by acceleration, deceleration and turning of the vehicle to enable the cleaning piece to move relative to the filter.

[0008] In the invention of mode 1, since the movable mechanism utilizes the inertial force generated by the acceleration, deceleration and steering of the vehicle to control the cleaning member to be relatively movable relative to the filter, no motor or electrical wiring is required, and the manufacturing cost can be reduced. In addition, since the inertial force generated by the acceleration, deceleration and steering of the vehicle is generated every time the vehicle is used, the filter can be cleaned frequently.

[0009] The invention of mode 2 is based on the invention of mode 1, and the movable mechanism has: a rod-shaped brush stand for holding the cleaning member; and a guide rail for sliding contact with the sliding contact parts formed at both ends or the center of the brush stand and supporting the sliding contact parts, and the brush stand can move back and forth along the long side direction of the guide rail, and the guide rail is arranged near the end or the center of the filter. In this way, the inertial force can be converted into a force along the linear direction of the filter for use.

[0010] The invention of mode 3 is based on the invention of mode 2, in which a buffer device is provided near both ends of the guide rail in the long side direction, and the buffer device generates a repulsive force on the brush table when the brush table approaches or abuts against the brush table, so as to alleviate the collision between the brush table and the guide rail. Thus, even when subjected to a large inertial force, damage to the movable mechanism can be prevented.

[0011] The invention of mode 4 is based on the invention of mode 2, and the load per unit length in the long side direction near the sliding contact part of the brush table supported by the guide rail is greater than the load per unit length outside the sliding contact part of the brush table. As a result, the inertial force acting on the brush table can be increased, and the deformation of the brush table is also suppressed, so that the brush table can slide smoothly on the guide rail.

[0012] The invention of mode 5 is based on the invention of mode 1, wherein the movable mechanism has a rod-shaped brush stand for holding the cleaning member, one end of the brush stand is rotatably fixed near the filter, and the other end is a free end that can rotate back and forth. Thus, the movable mechanism can be simplified and the manufacturing cost can be reduced.

[0013] The invention of mode 6 is based on the invention of any one of modes 1 to 5, wherein the movable mechanism is formed so that when the vehicle is viewed from the side, the movable direction of the cleaning member is inclined relative to the traveling direction of the vehicle. Thus, even when the vehicle is not acted upon by inertial force, the cleaning member can be moved toward one end of the filter due to the gravity, thereby preventing the cleaning member from stopping at the middle position of the filter and obstructing ventilation in the room.

[0014] The invention of mode 7 is based on the invention of mode 1, wherein the movable mechanism has a rotating shaft and a plate-shaped brush stand for holding a cleaning member, one end of the brush stand in the short side direction is rotatably fixed to the rotating shaft, and the other end is a free end that can rotate back and forth, and the cleaning member is held on the free end side. In this way, the movable mechanism can be simplified and the manufacturing cost can be reduced.

[0015] The filter cleaning device of the invention of method 8 is arranged in a vehicle air conditioning equipment, and the filter cleaning device comprises: a filter; a cleaning piece abutting against the filter to remove dust attached to the surface of the filter; and a movable mechanism directly or indirectly connected to the filter, and while maintaining the distance between the cleaning piece and the filter at a substantially constant, the filter is movably controlled, and the movable mechanism utilizes the inertial force generated by acceleration, deceleration and turning of the vehicle to enable the filter to move relative to the cleaning piece.

[0016] In the invention of mode 8, since the movable mechanism utilizes the inertial force generated by the acceleration, deceleration and steering of the vehicle to control the filter to be relatively movable relative to the cleaning member, a motor and electrical wiring are not required, and the manufacturing cost can be reduced. In addition, since the inertial force generated by the acceleration, deceleration and steering of the vehicle is generated every time the vehicle is used, the filter can be cleaned frequently.

[0017] The filter cleaning device of the invention of method 9 is arranged in a vehicle air conditioning equipment, and the filter cleaning device comprises: a filter; a cleaning piece, which abuts against the filter and removes dust attached to the surface of the filter; and a movable mechanism in a roughly cover-shaped manner, which is arranged at a position opposite to the filter across the cleaning piece, and while maintaining the distance between the cleaning piece and the filter at a roughly constant distance, the cleaning piece is controlled to be movable, and the movable mechanism utilizes the inertial force generated by acceleration, deceleration and turning of the vehicle to enable the cleaning piece to move relative to the filter.

[0018] In the invention of mode 9, since the movable mechanism formed in a substantially cover shape utilizes the inertial force generated by the acceleration, deceleration and turning of the vehicle to control the cleaning member to be relatively movable relative to the filter, a motor and electrical wiring are not required, and the manufacturing cost can be reduced. In addition, the inertial force generated by the acceleration, deceleration and turning of the vehicle is generated every time the vehicle is used, so the filter can be cleaned frequently.

[0019] The invention of mode 10 is based on the invention of any one of modes 1, 8 and 9, and a dust box is formed near the filter and at least on one side of the movable direction of the cleaning tool. Thus, the dust removed from the filter by the cleaning tool can be accumulated in the dust box, and the accumulated dust can be discharged to the outside in a concentrated manner.

[0020] According to the inventions of modes 1, 8 and 9, no motor or electrical wiring is required, and the manufacturing cost can be reduced. In addition, since the inertial force generated by the acceleration, deceleration and turning of the vehicle is generated every time the vehicle is used, the filter can be cleaned frequently. In addition, according to the invention of mode 2, the inertial force can be converted into a force along the linear direction of the filter for use.

[0021] According to the invention of mode 3, even when subjected to a large inertial force, the movable mechanism can be prevented from being damaged. In addition, according to the invention of mode 4, the inertial force acting on the brush table can be increased, and the deformation of the brush table can be suppressed, so that the brush table can slide smoothly on the guide rail. In addition, according to the inventions of modes 5 and 7, the movable mechanism can be simplified, and the manufacturing cost can be reduced.

[0022] According to the invention of mode 6, it is possible to prevent the cleaning tool from stopping at the middle position of the filter and obstructing ventilation. In addition, according to the invention of mode 10, the dust removed from the filter by the cleaning tool can be stored in the dust box, and the stored dust can be discharged to the outside in a concentrated manner.

[0024] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. However, the present invention is not limited to the embodiment. Figure 1 (a) is a cross-sectional view showing a state where the filter cleaning device of the present invention is installed in a vehicle air conditioning device, Figure 1 (b) is a perspective view showing a first embodiment of the filter cleaning device of the present invention. Figure 2 (a) is a side view when an inertial force acts toward the rear of the vehicle. Figure 2 (b) is a side view when an inertial force acts toward the front of the vehicle. A first embodiment of the filter cleaning device of the present invention will be described below with reference to these drawings.

[0025] The filter cleaning device 10 of the first embodiment is provided in a vehicle air conditioning device, such as Figure 1 As shown in (a), the fan 82 is provided on the upstream side (above) of the fan 82 provided inside the vehicle air conditioner main body box 81, and supplies the air having passed through the filter 1 into the room.

[0026] The filter cleaning device 10 comprises a filter 1, a cleaning piece 2 and a movable mechanism 3, wherein the cleaning piece 2 abuts against the filter 1 to remove dust attached to the surface of the filter 1, and the movable mechanism 3 is connected to the cleaning piece 2 to control the movement of the cleaning piece 2 while maintaining the distance between the cleaning piece 2 and the filter 1 approximately constant.

[0027] Moreover, the movable mechanism 3 utilizes the inertial force generated by the acceleration, deceleration and steering of the vehicle to enable the cleaning member 2 to move relative to the filter 1. Thus, no motor or electrical wiring is required, and the vehicle's electricity is not used, so there is no burden on the overall power consumption of the vehicle, the structure is environmentally friendly, and the manufacturing cost can be reduced. In addition, since the inertial force generated by the acceleration, deceleration and steering of the vehicle is generated every time the vehicle is used, the filter 1 can be cleaned frequently.

[0028] The movable mechanism 3 includes: a rod-shaped brush stand 4 for holding the cleaning member 2; and guide rails 5a, 5b for sliding contact with and supporting the sliding contact portions 4a, 4b formed at both ends of the brush stand 4. The brush stand 4 can reciprocate along the long side direction of the guide rails 5a, 5b, which are provided near both ends of the filter 1. Thus, the inertial force can be converted into a force along the linear direction of the filter 1 for utilization.

[0029] The guide rails 5a and 5b are provided with respective buffer devices 6a, 6b, 6c, and 6d near both ends in the long side direction, and the buffer devices 6a, 6b, 6c, and 6d are configured to generate a repulsive force on the brush table 4 when the brush table 4 approaches or abuts against it, thereby relieving the collision between the brush table 4 and the guide rails 5a and 5b. Thus, even when subjected to a large inertial force, the movable mechanism 3 can be prevented from being damaged.

[0030] The load per unit length in the long side direction near the sliding contact parts 4a and 4b supported by the guide rails 5a and 5b of the brush table 4 is set to be greater than the load per unit length outside the sliding contact parts 4a and 4b of the brush table. In this way, the inertial force acting on the brush table 4 can be increased, and the deformation of the brush table can also be suppressed, so that the brush table 4 can slide smoothly on the guide rails 5a and 5b.

[0031] Dust boxes 7a and 7b are formed near the filter 1 and on both sides of the movable direction of the cleaning member 2. In addition, as long as the dust boxes 7a and 7b are formed on at least one side of the movable direction of the cleaning member 2, it is included in the present invention. Thus, the dust removed from the filter 1 by the cleaning member 2 can be accumulated in the dust boxes 7a and 7b, and the accumulated dust can be discharged to the outside in a concentrated manner.

[0032] In addition, the movable mechanism 3 is preferably formed so that, when the vehicle is viewed from the side, the movable direction of the cleaning member 2 is inclined relative to the traveling direction of the vehicle. Thus, even when the vehicle is not subjected to inertial force, the cleaning member can be moved toward one end of the filter 1 due to gravity, thereby preventing the cleaning member 2 from stopping at the middle position of the filter 1 and obstructing ventilation in the room.

[0033] Here, the inertial force is generated by the acceleration, deceleration and steering of the vehicle. When the vehicle is accelerating, Figure 2 As shown in (a), since the inertial force acts from the front to the rear of the driver, the movable mechanism 3 of the filter cleaning device 10 also acts from the front to the rear of the vehicle, so that the cleaning member 2 located on the vehicle front side of the filter 1 can move toward the vehicle rear side of the filter 1. On the contrary, when the vehicle is decelerated, as shown in FIG. Figure 2As shown in (b), since an inertial force acts from the rear of the driver toward the front, the movable mechanism 3 of the filter cleaning device 10 also acts from the rear of the vehicle toward the front, so that the cleaning member 2 located on the rear side of the filter 1 can move toward the front side of the filter 1. In addition, although not shown in the figure, the inertial force is also generated by changing the direction of travel of the vehicle by turning, so that the cleaning member 2 can move relative to the filter 1.

[0034] Figure 3 (a) is a stereoscopic view showing the first embodiment of the cleaning tool. In addition, for ease of understanding, the sliding contact portion of the brush stand 4 is not depicted (the same applies below). The cleaning tool 2a of the first embodiment is formed of a sponge as a synthetic resin porous body, and a base formed at one end is slidably fixed to the groove portion 4c of the brush stand 4.

[0035] Figure 3 (b) is a perspective view showing a second embodiment of the cleaning tool. The cleaning tool 2b of the second embodiment is formed of a brush bristle material, and a base formed at one end is slidably fixed to the groove 4c of the brush stand 4. In addition, the material of the brush bristle material can be various materials such as nylon, PP, PE, and natural fiber.

[0036] Figure 3 (c) is a perspective view showing a third embodiment of the cleaning tool. The cleaning tool 2c of the third embodiment is formed by a scraper made of soft synthetic resin, and a base formed at one end is slidably fixed to the groove 4c of the brush stand 4. In addition, in this figure, protrusions 4d, 4d are formed on the side of the scraper, but a scraper without protrusions may also be used.

[0037] Figure 3 (d) is a perspective view showing a fourth embodiment of the cleaning tool. The cleaning tool 2d of the fourth embodiment is formed of a nonwoven fabric, and a base formed at one end is slidably fixed to the groove 4c of the brush base 4.

The buffer device 6a of the first embodiment is formed near the two ends of the long side direction of the guide rail 5a, and an insertion hole 6g for inserting the convex portion 4d is formed on the side. In addition, a spring 6h is provided in the insertion hole 6g as a biasing member, and the convex portion 4d of the brush table 4 is configured so that the spring 6h will be rebounded if it is pressed. Thus, even when subjected to a large inertial force, damage to the movable mechanism can be prevented.

[0039] Figure 4(b) is a cross-sectional view showing a second embodiment of the buffer device. The buffer device 6e of the second embodiment is formed near the two ends of the long side direction of the guide rail 5a, and an insertion hole 6g is formed on the side for inserting the convex portion 4e formed by a magnet. In addition, a magnet 6i is provided in the insertion hole 6g, and the magnet 6i has the same magnetic pole as the opposite surface of the convex portion 4e on the convex portion 4e side, and the convex portion 4e of the brush table 4 will be rebounded if it approaches the magnet 6i. In this way, even when subjected to a large inertial force, damage to the movable mechanism can be prevented.

[0040] Figure 4 (c) is a cross-sectional view showing a third embodiment of the buffer device. The buffer device 6f of the third embodiment is formed near the two ends of the long side direction of the guide rail 5a, and an insertion hole 6g is formed on the side for inserting the convex portion 4f composed of a soft member. In addition, a cushion member 6j composed of a soft member is provided in the insertion hole 6g, and is configured so that if the convex portion 4f of the brush table 4 abuts against the cushion member 6j, both are deformed to absorb the impact force. Thus, even when subjected to a large inertial force, damage to the movable mechanism can be prevented.

[0041] Figure 5 2 is a perspective view showing a second embodiment of the filter cleaning device of the present invention. In the filter cleaning device 20 of the second embodiment, the filter 21 adopts a corrugated pleated filter, and the top of the cleaning member 22 is formed into a corrugated shape corresponding to the filter 21. By adopting a pleated filter, the surface area can be increased and the collection efficiency can be improved. The other structures are the same as those of the first embodiment, so the description is omitted.

In the filter cleaning device 30 of the third embodiment, the guide rail 35 is arranged near the central part of the filter 1, and the sliding contact part 34a is formed in the central part of the brush stand 34. Thus, the filter cleaning device 10 of the first embodiment can be manufactured more cheaply, and the manufacturing cost can be reduced. The other structures are the same as those of the first embodiment, so the description is omitted.

[0043] Figure 7: is a stereoscopic diagram showing the fourth embodiment of the filter cleaning device of the present invention. In the filter cleaning device 40 of the fourth embodiment, the movable mechanism 43 has a rod-shaped brush stand 44 for holding the cleaning member 42, one end of the brush stand 44 is fixed to the shaft body 8 in a rotatable manner, and the other end of the brush stand 44 becomes a free end that can rotate back and forth, and the shaft body 8 is arranged on a base near the filter 41 that is fan-shaped when viewed from above. In addition, magnets 46 are arranged at two locations of the shaft body 8, and magnets (not shown) are also arranged on the brush stand 44 corresponding thereto, so that the surfaces facing each other become the same magnetic poles, and the function of the buffer device described in the first embodiment is exerted. In this way, the movable mechanism 43 can be simplified, and the manufacturing cost can be reduced. The other structures are the same as those in the first embodiment, so the description is omitted. In addition, in this embodiment, the inertial force is also generated by changing the direction of travel of the vehicle by turning, so that the cleaning member 42 can move relative to the filter 41.

[0044] Figure 8 : is a stereoscopic diagram showing the fifth embodiment of the filter cleaning device of the present invention. In the filter cleaning device 50 of the fifth embodiment, the movable mechanism 53 has: a base having a ventilating port for setting the filter 51; a bearing, which is set on the base; a rotating shaft 9, which is pivotally supported on the bearing; and a plate-shaped brush stand 54, which holds the cleaning member 52. One end of the brush stand 54 in the short side direction is fixed to the rotating shaft 9 in a rotatable manner, and the other end becomes a free end that can rotate back and forth, and the cleaning member 52 is held on the free end side. In addition, the filter 51 forms an arc shape when viewed from the side, and the inertial force generated by the acceleration, deceleration and steering of the vehicle is used to make the cleaning member 52 rotate back and forth while sliding in contact with the filter 51, thereby cleaning. As a result, the movable mechanism 53 can be simplified, and the manufacturing cost can be reduced.

[0045] Fig. 9 6 is a perspective view showing a sixth embodiment of the filter cleaning device of the present invention. The filter cleaning device 60 of the sixth embodiment comprises: a filter 61; a cleaning member 62 abutting against the filter 61 to remove dust attached to the surface of the filter 61; and a movable mechanism 63 directly or indirectly connected to the filter 61, and controlling the filter 61 to be movable while keeping the distance between the cleaning member 62 and the filter 61 substantially constant. Moreover, the movable mechanism 63 is configured to utilize the inertial force generated by the acceleration, deceleration and steering of the vehicle so that the filter 61 can move relative to the cleaning member 62. Specifically, a track having a U-shape in a side view is provided at both ends of the long side direction of the filter 61, and the filter 61 and the belt fixedly installed at both ends of the short side direction of the filter 61 can move on the track by means of rollers, and the cleaning member 62 cleans by sliding contact with the filter 61 that moves back and forth by utilizing the inertial force, and the cleaning member 62 is held by a brush stand fixed to the middle part of the left and right tracks.

[0046] The filter cleaning device 60 of the sixth embodiment is configured as a movable mechanism that uses the inertial force generated by the acceleration, deceleration and steering of the vehicle to control the filter 61 to be relatively movable relative to the cleaning member 62, so no motor or electrical wiring is required, and the manufacturing cost can be reduced. In addition, since the inertial force generated by the acceleration, deceleration and steering of the vehicle is generated every time the vehicle is used, the filter 61 can be cleaned frequently.

[0047] Fig.10 : is a stereoscopic diagram showing the seventh embodiment of the filter cleaning device of the present invention. The filter cleaning device 70 of the seventh embodiment comprises: a filter 71; a cleaning member 72, which abuts against the filter 71 and removes dust attached to the surface of the filter 71; and a movable mechanism 73 having a substantially cover shape and a ventilation hole 12, which is arranged at a position opposite to the filter 71 across the cleaning member 72, and the cleaning member 72 is controlled to be movable while the distance between the cleaning member 72 and the filter 71 is kept substantially constant. Moreover, the movable mechanism 73 is configured to utilize the inertial force generated by the acceleration, deceleration and steering of the vehicle so that the cleaning member 72 can move relative to the filter 71. In addition, the four sides of the filter 71 are surrounded by the side walls 11, 11 of the base having a ventilation hole, so as to prevent the cleaning member 72 from detaching from the filter 71, and the ventilation hole is provided with the filter 71.

[0048] The filter cleaning device 70 of the seventh embodiment is constituted as a movable mechanism 73 in a substantially cover shape, and uses the inertial force generated by the acceleration, deceleration and steering of the vehicle to control the cleaning member 72 to be relatively movable relative to the filter 71, so that no motor or electrical wiring is required, and the manufacturing cost can be reduced. In addition, the inertial force generated by the acceleration, deceleration and steering of the vehicle is generated every time the vehicle is used, so the filter 71 can be cleaned frequently. In addition, in this embodiment, even if the direction of travel of the vehicle is changed by steering, an inertial force is generated, so that the cleaning member 72 can be relatively movable relative to the filter 71.
