Description

Technical Field

[0001] The present disclosure relates to a cleaner for a vehicle. Background Art

[0002] In recent years, the number of vehicles equipped with on-board cameras for photographing conditions around the vehicle has been increasing. In the case of on-board cameras, the lens, which is the photographing surface, may be dirty due to rain or mud. Therefore, in order to remove foreign matter such as water droplets attached to the lens, there is a known device for blowing cleaning fluid or compressed air to the lens of the on-board camera to remove foreign matter (see Patent Document 1).

[0003] In the foreign matter removal device of Patent Document 1, a compressed air generating unit is provided near the vehicle-mounted camera, and compressed air from the compressed air generating unit is ejected from a nozzle to blow high-pressure air onto the lens of the vehicle-mounted camera, thereby removing water droplets attached to the lens.

[0006] Patent Document 1: Japanese Patent Application Publication No. 2001-171491 Summary of the invention

[0007] Problems to be solved by the invention

[0008] However, the air supply unit such as the compressed air generating unit takes in external air from the inlet. Therefore, when taking in air, foreign matter may enter the air supply unit from the inlet.

[0009] In addition, the air supply unit has a driving unit for driving the air supply unit main body. The vibration of the driving unit may be transmitted to the air supply unit main body and affect the operation of the air supply unit main body. In addition, vibration sound may be generated due to the vibration of the driving unit.

[0010] In addition, when the washer fluid is sprayed from the nozzle, the washer fluid remains at the front end of the nozzle, and sometimes the washer fluid droplets are reflected on the vehicle camera. In addition, the nozzle spray port may be clogged due to foreign matter (mud or garbage, etc.) attached to the nozzle spray port or raindrops freezing at the nozzle spray port.

[0011] One of the objects of the present disclosure is to provide a vehicle cleaner that prevents foreign matter from entering an interior of an air supply unit.

[0012] Another object of the present disclosure is to provide a vehicle cleaner that suppresses the vibration of a driving unit from being propagated to a blower unit main body.

[0013] Another object of the present disclosure is to provide a vehicle cleaner capable of removing water droplets or foreign matter attached to the tip of a nozzle and a jet port.

[0014] Technical solutions to solve problems

[0015] One aspect of the present disclosure provides a vehicle cleaner comprising:

[0016] an air supply unit having an inlet for taking in air to be sprayed toward the cleaning object;

[0017] The filter is arranged at the inlet to prevent foreign matter from entering the air supply unit and allows air to pass through.

[0018] According to the above structure, the filter is provided at the inlet of the air supply unit, so that foreign matter can be prevented from entering the interior of the air supply unit. For example, foreign matter such as garbage can be prevented from entering the interior of the air supply unit when air is taken in.

[0019] Furthermore, the filter may be attachable to and detachable from the inlet of the air supply unit.

[0020] According to the above configuration, when the filter is deteriorated, it can be replaced with a new filter.

[0021] Furthermore, the intake port of the air supply unit may take in air outside the vehicle.

[0022] When the intake port takes in air outside the vehicle, there is a high possibility that more foreign matter will enter. According to the above configuration, it is possible to prevent foreign matter from entering the interior of the air supply unit.

[0023] Furthermore, the air supply unit may be a non-volumetric air supply unit that continuously takes in the air.

[0024] In the case of the non-volumetric air supply unit, since air is continuously taken in, there is a high possibility that more foreign matter will enter. According to the above configuration, it is possible to prevent foreign matter from entering the interior of the non-volumetric air supply unit.

[0025] Furthermore, the air supply unit may include a bracket for housing the air supply unit, wherein the bracket has a drain hole for draining water that enters from an inlet of the air supply unit.

[0026] According to the above configuration, water that has entered through the inlet of the air supply unit can be discharged to the outside.

[0027] Furthermore, a heating unit may be provided in the vicinity of an inlet of the air supply unit.

[0028] According to the above structure, it is possible to prevent the snow from being blown up during snowfall or when the snow accumulated on the road surface is attached to the inlet or the periphery of the inlet. In addition, it is also possible to prevent the water droplets attached to the inlet or the periphery of the inlet from freezing.

[0029] One aspect of the present disclosure provides a vehicle cleaner comprising:

[0030] An air supply unit having an air supply unit main body for supplying air to be sprayed toward a cleaning object, a support unit for at least supporting the air supply unit main body, and a drive unit for driving the air supply unit main body;

[0031] The vibration-proof part suppresses the vibration of the driving part from being propagated to the supporting part.

[0032] According to the above structure, the vibration-proof part suppresses the vibration of the driving part from being propagated to the support part. Therefore, the vibration of the driving part can be suppressed from being propagated to the air supply part body via the support part. In addition, the generation of vibration sound caused by the vibration of the driving part can be suppressed.

[0033] Furthermore, the vibration-proof part may include an elastic member for absorbing vibration of the driving part and a mounting part for mounting the elastic member on the driving part.

[0034] The support portion is attached to the elastic member so as to be in a non-contact state with the driving portion.

[0035] According to the above structure, the vibration of the driving part is absorbed by the elastic member, so the vibration of the driving part can be suppressed from being propagated to the support part. In addition, the support part and the driving part are in a non-contact state, so the vibration of the driving part can be suppressed from being propagated to the support part.

[0036] In addition, the mounting portion may have a rod shape, the elastic component may have a cylindrical shape having a through hole, a groove recessed in a direction orthogonal to the axial direction of the through hole may be formed on the side of the elastic component, the mounting portion may be inserted into the through hole, and a portion of the supporting portion may be inserted into the groove.

[0037] According to the above structure, the elastic component can be simply installed on the driving part by inserting the mounting part into the through hole of the elastic component. In addition, the supporting part is installed on the elastic component by inserting a part of it into the groove formed on the side of the elastic component. In the case of increasing the size of the elastic component in order to improve the vibration-proof effect, it is sufficient to increase the size of the elastic component in a direction orthogonal to the axial direction of the through hole instead of in the axial direction of the through hole. Therefore, the vibration-proof effect can be improved without enlarging the supporting part and / or the air supply part as a whole.

[0038] Furthermore, the vibration-proof portion may further include a holder portion that surrounds the driving portion in a state of being in contact with the driving portion, and the mounting portion may be formed integrally with the holder portion.

[0039] According to the above configuration, the mounting portion can be stably mounted on the driving portion by the holder portion. In addition, the vibration of the driving portion can be transmitted to the elastic member via the holder portion and the mounting portion, and the vibration can be absorbed by the elastic member.

[0040] Furthermore, the vibration-proof portion may include at least three mounting portions arranged around the driving portion, and at least three elastic members mounted to the driving portion via the three mounting portions.

[0041] According to the above structure, the mounting part is arranged at least three places around the driving part. For example, when the mounting part is arranged at only two places around the driving part, the driving part may rotate relative to the supporting part around the axial direction of the mounting part. In contrast, by arranging the mounting part at at least three places around the driving part, the driving part can be prevented from rotating relative to the supporting part around the axial direction of the mounting part.

[0042] Furthermore, the vibration-proof portion may include a holder portion that supports the driving portion and is connected to the supporting portion, and the holder portion may include a leaf spring portion that absorbs vibration of the driving portion.

[0043] According to the above configuration, by absorbing the vibration of the driving portion by the leaf spring portion, it is possible to suppress the vibration of the driving portion from being propagated to the supporting portion while supporting the driving portion by the holder portion.

[0044] Furthermore, the holder portion may include a flange portion in contact with the support portion, the leaf spring portion may extend from the flange portion along the drive portion in a non-contact state with the drive portion, and a front end portion of the leaf spring portion may be in contact with the drive portion.

[0045] According to the above configuration, the leaf spring portion absorbs the vibration of the driving portion propagated from the front end portion thereof, thereby suppressing the vibration from propagating to the flange portion.

[0046] Furthermore, the holder portion may include a rotation restraining portion that is locked to the support portion and restrains rotation of the holder portion relative to the support portion.

[0047] According to the above configuration, the rotation suppressing portion can suppress the holder portion from rotating relative to the support portion due to vibration of the drive portion.

[0048] One aspect of the present disclosure provides a vehicle cleaner, wherein:

[0049] A nozzle is provided, the nozzle having a cleaning liquid injection port for injecting cleaning liquid onto a cleaning surface of a cleaning object, and two air injection ports for injecting air onto the cleaning surface of the cleaning object,

[0050] The two air injection ports are arranged on both sides of the cleaning liquid injection port.

[0051] According to the above structure, water droplets or foreign matter attached to the front end and the injection port of the nozzle can be removed by air ejected from the air injection port. For example, water droplets or foreign matter attached to the front end and the injection port of the cleaning liquid can be removed by ejecting air from the air injection port. The water droplets are, for example, residual cleaning liquid or rainwater. In addition, the air injection port and the cleaning liquid injection port are formed on one nozzle, so the appearance of the vehicle cleaner is improved compared with the case where a plurality of nozzles are provided.

[0052] Furthermore, the two air ejection ports may be located on both sides of the cleaning liquid ejection port in a first direction, and a width of the air ejection port in a second direction perpendicular to the first direction may be greater than a width of the cleaning liquid ejection port in the second direction.

[0053] According to the above configuration, the width of the air injection port in the second direction is large, so the air can be injected without hindering the air flow. On the other hand, the width of the cleaning liquid injection port in the second direction is narrow, so the cleaning liquid can be injected while being widely spread.

[0054] Furthermore, the two air ejection ports may be located on both sides of the cleaning liquid ejection port in the first direction, and the width of the air ejection port in the first direction may be wider than the width of the cleaning liquid ejection port in the first direction.

[0055] According to the above configuration, the width of the air injection port in the first direction is large, so the air can be injected without hindering the air flow. On the other hand, the width of the cleaning liquid injection port in the first direction is narrow, so the cleaning liquid can be injected while being widely spread.

[0056] Furthermore, the area of ​​a surface of the air ejection port orthogonal to the ejection direction of the air may be larger than the area of ​​a surface of the cleaning liquid ejection port perpendicular to the ejection direction of the cleaning liquid.

[0057] According to the above configuration, the air injection port has a wide area, so the air can be injected without hindering the air flow. On the other hand, the cleaning liquid injection port has a narrow area, so the cleaning liquid can be injected while being widely spread.

The bracket 5 and the bracket cover 6 are examples of a bracket.

[0108] [Multi-blade fan 4]

[0109] First, the main reference Figure 6 to Figure 8 The multi-blade fan 4 will be described. Figure 6 It is an exploded perspective view of the multi-blade fan 4. Figure 7 It is an axial cross-sectional view of the multi-blade fan 4. Figure 8 It is a radial cross-sectional view of the multi-blade fan 4. In the following description, for convenience, the side of the multi-blade fan 4 where the impeller 11 of the multi-blade fan body 10 is provided is referred to as the front, and the opposite side is referred to as the rear.

[0110] The multi-blade fan 4 is configured to continuously take in air from the outside and continuously send out the taken-in air. Figure 6 As shown, the multi-blade fan 4 includes a multi-blade fan main body 10, a driving unit 20, and a vibration-proofing unit 30. The multi-blade fan main body 10 is an example of an air supply unit main body.

[0111] The multi-blade fan main body 10 is configured to take in the air to be blown toward the vehicle-mounted camera 2 and to send out the taken-in air. The multi-blade fan main body 10 includes an impeller 11 , a housing 12 , and a support portion 13 .

[0112] The impeller 11 can be rotated around the rotation axis Ax by the driving unit 20. The impeller 11 has a disk-shaped main disk 11a and a plurality of blades 11b. The plurality of blades 11b are formed to extend in the radial direction. The plurality of blades 11b are mounted on the main disk 11a to form a ring shape. Figure 7 As shown, the main disk 11a has a cylindrical shaft portion 11c extending from the rear surface along the rotation axis Ax. The shaft portion 11c has a rotation shaft hole 11d for inserting the rotation shaft 21b of the motor 21 of the driving unit 20. When the motor 21 is driven, as the rotation shaft 21b of the motor 21 rotates, the shaft portion 11c of the main disk 11a also rotates, and the impeller 11 rotates around the rotation axis Ax.

[0113] The housing 12 has a substantially donut-shaped internal space inside, and the impeller 11 is accommodated in the internal space. The housing 12 has an air intake port 12a, an air outlet 12b, and a drain port 12c (see Figure 4B). The air intake port 12a is an opening for taking in air from the outside. The air outlet port 12b is an opening for sending out the air taken in from the air intake port 12a. The drain port 12c is an opening for discharging water that has entered the interior of the multi-blade fan 4. The air intake port 12a opens on the extension line of the rotation axis Ax of the impeller 11. The air outlet port 12b opens in a direction that intersects with the rotation axis Ax of the impeller 11. The drain port 12c opens in a direction that intersects with the rotation axis Ax of the impeller 11. The drain port 12c connects the internal space of the housing 12 to the outside. The drain port 12c opens at the bottom of the housing 12 when the vehicle cleaner 3 is installed on the vehicle V. The water that has penetrated into the interior of the housing 12 falls to the outside through the drain port 12c, so that the water does not accumulate in the interior of the housing 12.

[0114] The housing 12 includes a front housing 12A and a rear housing 12B which are divided into two parts in a manner of sandwiching the impeller 11. The front housing 12A has bracket mounting portions 12d at two opposite locations on the side. The multi-blade fan 4 is fixed to the bracket 5 via the bracket mounting portions 12d. Figure 7 As shown, the rear housing 12B has an opening 12e at its center into which the shaft portion 11c of the main disk 11a of the impeller 11 is inserted. A sealing member 14 is arranged between the opening 12e of the rear housing 12B and the shaft portion 11c of the main disk 11a of the impeller 11. The sealing member 14 prevents water and the like from entering the driving portion 20 from the housing 12 and allows the impeller 11 to rotate about the rotation axis Ax.

[0115] When the impeller 11 rotates, the air sucked from the air inlet 12a is pushed against the inner peripheral surface of the rear housing 12B by the blades 11b. The pushed air is guided along the inner peripheral surface of the rear housing 12B and guided to the air outlet 12b, and is sent from the air outlet 12b to the air duct forming part 70 of the bracket 5. That is, the air sucked from the direction of the rotation axis Ax of the impeller 11 is pushed out in the radial direction by the rotating blades 11b, and is pushed against the inner peripheral surface of the rear housing 12B, and is sent from the air outlet opened in the radial direction to the air duct forming part 70 of the bracket 5.

[0116] like Figure 7 As shown, the support portion 13 supports the housing 12. The support portion 13 is connected to the motor 21 of the drive unit 20 via the vibration-proof portion 30. In addition, the support portion 13 accommodates the front portion of the motor 21 of the drive unit 20 therein. In this embodiment, the support portion 13 is integrally formed with the housing 12. The support portion 13 has an octagonal cross-section (see FIG. 1 ) extending rearward along the rotation axis Ax from the rear surface of the rear housing 12B.

The support portion 13 is connected to the motor case 22 of the drive unit 20 by engaging the engagement claw 22 c of the motor case 22 of the drive unit 20 with the engagement hole 13 a.

[0117] It should be noted that the support portion 13 is integrally formed with the housing 12. However, for example, the support portion 13 may be formed separately from the housing 12 and integrated by being assembled or bonded to the housing 12. In addition, the cross section of the support portion 13 is an octagon. However, for example, the cross section of the support portion 13 may also have a polygon other than a circle, an ellipse, or an octagon.

[0118] The driving unit 20 is configured to drive the multi-blade fan body 10 . The driving unit 20 includes a motor 21 and a motor housing 22 .

[0119] The motor 21 rotates the impeller 11 around the rotation axis Ax. The motor 21 has a motor body 21a and a rotation shaft 21b. The motor body 21a has a substantially prism shape. The rotation shaft 21b extends forward along the rotation axis Ax from the front surface of the motor body 21a. The rotation shaft 21b is inserted into the rotation shaft hole 11d of the shaft portion 11c of the main disk 11a.

[0120] The motor housing 22 accommodates and supports the motor 21. The motor housing 22 includes a motor housing portion 22a and a support portion mounting portion 22b. The motor housing portion 22a accommodates the rear portion of the motor 21. The support portion mounting portion 22b extends forward from the front end of the motor housing portion 22a.

[0121] It should be noted that the support portion 13 has the engagement hole 13a, and the motor housing 22 has the engagement claw 22c. However, the support portion 13 may have the engagement claw, and the motor housing 22 may have the engagement hole.

[0122] The vibration-proof part 30 is configured to suppress the vibration of the driving part 20 from being propagated to the supporting part 13. The vibration-proof part 30 includes a plurality of elastic members 31, a plurality of elastic member mounting parts 32 (hereinafter referred to as mounting parts 32), and a cage part 33.

[0123] The elastic member 31 absorbs the vibration of the motor 21 and suppresses the vibration of the motor 21 from propagating to the support portion 13. The elastic member 31 is, for example, a vibration-proof rubber having a cylindrical shape with a through hole 31a. The mounting portion 32 is provided so as to be in contact with the motor 21. The elastic member 31 is mounted to the motor 21 via the mounting portion 32. The mounting portion 32 has, for example, a rod shape that can be inserted into the through hole 31a of the elastic member 31. Figure 7 and Figure 8As shown in FIG. 1 , the elastic member 31 is provided so as to be in contact with the mounting portion 32 and the support portion 13. The support portion 13 is mounted on the elastic member 31 in a non-contact state with the motor 21. Figure 6 As shown, the holder portion 33 is formed to surround the motor 21 while being in contact with the motor 21. In this embodiment, the holder portion 33 includes a front holder portion 33A and a rear holder portion 33B that are divided in a manner of sandwiching the motor 21. The mounting portion 32 is integrally formed with the holder portion 33 and includes a front mounting portion 32A and a rear mounting portion 32B.

[0124] The mounting portion 32 is arranged at four locations around the motor 21 and extends in the radial direction of the motor 21. The elastic member 31 is mounted on the mounting portion 32 by inserting the mounting portion 32 into the through hole 31a of the elastic member 31. In addition, a groove 31b is formed on the side surface of the elastic member 31 over the entire circumference, and is recessed in a direction orthogonal to the axial direction of the through hole 31a. The support portion 13 is mounted on the motor 21 via the elastic member 31 by inserting a part of the support portion 13 into the groove 31b of the elastic member 31. The vibration of the motor 21 transmitted to the elastic member 31 via the holder portion 33 and the mounting portion 32 is absorbed by the elastic member 31.

[0125] The motor case 22 is connected to the support portion 13 via the elastic member 31 by inserting a portion of the motor case 22 into the groove 31b of the elastic member 31. The vibration of the motor 21 transmitted to the elastic member 31 via the motor case 22 is absorbed by the elastic member 31.

[0126] It should be noted that the mounting portion 32 is integrally formed with the holder portion 33. However, the mounting portion 32 may be formed separately from the holder portion 33 and may be integrated by assembly or bonding.

[0127] In addition, the mounting portion 32 and the elastic member 31 are arranged at four locations around the motor 21. The number and arrangement of the mounting portions 32 and the elastic member 31 are not limited to being arranged at four locations. For example, when the mounting portions 32 and the elastic member 31 are arranged at three locations around the motor 21, the motor 21 can be prevented from rotating with respect to the support portion 13 around the axial direction of the mounting portion 32.

[0128] In addition, the holder portion 33 is formed so as to surround the entire circumference of the motor 21. However, for example, the holder portion 33 may be formed so as to surround a portion of the motor 21.

[0129] The groove 31b of the elastic member 31 is formed over the entire circumference of the side surface of the elastic member 31. However, for example, the groove 31b may be formed in a part of the side surface of the elastic member 31.

[0130] The shapes of the mounting portion 32 and the elastic member 31 are not limited to the present embodiment. The mounting portion 32 and the elastic member 31 may be in other shapes as long as they can absorb the vibration of the motor 21 and suppress the vibration of the motor 21 from propagating to the support portion 13. When the elastic member 31 has a cylindrical shape, the shape can be enlarged in a direction orthogonal to the axial direction of the through hole 31a rather than in the axial direction of the through hole 31a, so that the vibration of the motor 21 can be further absorbed.

[0131] Thus, in this embodiment, the vibration isolating portion 30 is used to suppress the vibration of the motor 21 from being propagated to the support portion 13. Therefore, the vibration of the motor 21 can be suppressed from being propagated to the multi-blade fan body 10 of the multi-blade fan 4 via the support portion 13. In addition, the generation of vibration sound caused by the vibration of the motor 21 can be suppressed.

[0132] In addition, the elastic member 31 of the vibration-proof part 30 is mounted on the motor 21 via the mounting part 32. The support part 13 is mounted on the elastic member 31 in a non-contact state with the motor 21. Therefore, the vibration of the motor 21 is absorbed by the elastic member 31, and the vibration of the motor 21 can be suppressed from propagating to the support part 13. In addition, the support part 13 is in a non-contact state with the motor 21, so the vibration of the motor 21 can be suppressed from propagating to the support part 13.

[0133] In addition, the elastic member 31 is mounted on the mounting portion 32 by inserting the rod-shaped mounting portion 32 into the through hole 31a of the elastic member 31. In addition, the support portion 13 is mounted on the elastic member 31 by inserting a part of it into the groove 31b formed on the side of the elastic member 31. In the case of increasing the size of the elastic member 31 in order to improve the vibration-proof effect, the elastic member 31 can be increased in a direction orthogonal to the axial direction of the through hole 31a rather than in the axial direction of the through hole 31a. Therefore, the vibration-proof effect can be improved without enlarging the support portion 13 and / or the multi-blade fan 4 as a whole.

[0134] The holder portion 33 surrounds the motor 21 while being in contact with the motor 21. The mounting portion 32 can be stably mounted on the motor 21 by the holder portion 33. The vibration of the motor 21 can be transmitted to the elastic member 31 via the holder portion 33 and the mounting portion 32, and the vibration can be absorbed by the elastic member 31.

[0135] In addition, the mounting portion 32 and the elastic member 31 are preferably arranged at least three locations around the motor 21. For example, when the mounting portion 32 is arranged at only two locations around the motor 21, the motor 21 may rotate with respect to the support portion 13 around the axial direction of the mounting portion 32. In contrast, by arranging the mounting portion 32 at least three locations around the motor 21, it is possible to prevent the motor 21 from rotating with respect to the support portion 13 around the axial direction of the mounting portion 32.

[0136] In addition, a part of the motor case 22 is attached to the elastic member 31. Since the vibration of the motor 21 transmitted to the elastic member 31 via the motor case 22 is absorbed by the elastic member 31, the vibration of the motor 21 can be suppressed from being transmitted to the support portion 13.

[0137] [Bracket 5]

[0138] Next, the main reference Figure 4A , Figure 4B and Figure 5 The bracket 5 will be described.

[0139] The bracket 5 supports and fixes the backup camera 2A and the rear view camera 2B. In addition, the bracket 5 accommodates the multi-blade fan 4 and delivers the air sent out from the multi-blade fan 4 to the backup camera 2A and the rear view camera 2B.

[0140] like Figure 4B As shown, the bracket 5 includes a camera mounting portion 50, a multi-blade fan storage portion 60, and an air duct forming portion 70. The camera mounting portion 50 includes a reversing camera mounting portion 50A and a rear view camera mounting portion 50B.

[0141] The camera mounting portion 50 is arranged to protrude forward from the front surface of the flat plate portion of the bracket 5. The multi-blade fan housing portion 60 is formed by being recessed rearward from the front surface of the flat plate portion of the bracket 5. The air duct forming portion 70 is formed by being recessed rearward from the front surface of the flat plate portion of the bracket 5. The portion of the front surface of the flat plate portion of the bracket 5 corresponding to the multi-blade fan housing portion 60 and the air duct forming portion 70 is opened. When viewed from a direction orthogonal to the direction of air delivered from the air delivery port 12b of the multi-blade fan 4 (hereinafter referred to as the air delivery direction), the multi-blade fan housing portion 60, the reversing camera mounting portion 50A, and the rearview camera mounting portion 50B are arranged in this order. In the present embodiment, the direction orthogonal to the air delivery direction is Figure 4B The front-to-back direction of the bracket 5 ( Figure 6 The air guide duct forming portion 70 extends from the multi-blade fan housing portion 60 along the arrangement direction of the backup camera mounting portion 50A and the rear view camera mounting portion 50B.

[0142] The camera mounting portion 50 is used to mount and fix the vehicle-mounted camera 2 on the bracket 5. The backing camera 2A and the rear-view camera 2B are mounted on the upper surfaces of the backing camera mounting portion 50A and the rear-view camera mounting portion 50B, respectively, by fastening members (not shown). The backing camera mounting portion 50A has a through hole 50Aa at its center to receive the wiring connected to the backing camera 2A. The rear-view camera mounting portion 50B has a through hole 50Ba at its center to receive the wiring connected to the rear-view camera 2B.

[0143] It should be noted that the reversing camera 2A and the rear view camera 2B are mounted on the upper surfaces of the reversing camera mounting portion 50A and the rear view camera mounting portion 50B, but may be partially housed inside the reversing camera mounting portion 50A and the rear view camera mounting portion 50B.

[0144] The multi-blade fan storage portion 60 stores the multi-blade fan 4. Figure 4B and Figure 5 As shown, the multi-blade fan storage portion 60 has a recess 61 that is recessed from the front surface of the flat plate portion of the bracket 5 to the rear. The recess 61 has a shape corresponding to the outer shell 12 of the multi-blade fan main body 10 of the multi-blade fan 4, and stores the outer shell 12 of the multi-blade fan main body 10 of the multi-blade fan 4. An opening 61a is formed on the bottom surface of the recess 61. The support portion 13 and the motor 21 of the multi-blade fan main body 10 of the multi-blade fan 4 are inserted through the opening 61a. The multi-blade fan 4 is stored in the multi-blade fan storage portion 60 in a state where the support portion 13 and the motor 21 of the multi-blade fan main body 10 protrude from the bracket 5 to the rear through the opening 61a.

[0145] The multi-blade fan storage portion 60 has a multi-blade fan mounting portion 61b at two locations opposite to each other on the side of the recess 61. The bracket mounting portion 12d of the multi-blade fan 4 is mounted on the multi-blade fan mounting portion 61b by a fastening member. The sealing member 62 is arranged around the opening 61a of the bottom surface of the recess 61. When the multi-blade fan 4 is mounted on the bracket 5, the housing 12 of the multi-blade fan main body 10 is pushed against the sealing member 62, and the sealing member 62 is elastically deformed, whereby the multi-blade fan 4 is sealed relative to the opening 61a of the bracket 5.

[0146] The multi-blade fan housing 60 has a drainage passage 60c connected to the drainage port 12c of the multi-blade fan 4. The drainage passage 60c is an example of a drainage hole. The drainage passage 60c is a space connected to the drainage port 12c of the multi-blade fan 4 when the multi-blade fan 4 is stored in the multi-blade fan housing 60. Water discharged from the drainage port 12c of the multi-blade fan 4 is discharged from the drainage passage 60c of the multi-blade fan housing 60.

[0147] The multi-blade fan storage portion 60 is connected to the air duct forming portion 70. The portion of the side surface of the recessed portion 61 of the multi-blade fan storage portion 60 that is opposite to the air outlet 12b of the multi-blade fan 4 opens in the air outlet direction of the air outlet 12b of the multi-blade fan 4 (in the present embodiment, the left direction of the bracket 5). When the multi-blade fan 4 is stored in the multi-blade fan storage portion 60, the air outlet 12b of the multi-blade fan 4 is connected to the air duct forming portion 70, and the air sent out from the air outlet 12b of the multi-blade fan 4 is transported to the air duct forming portion 70. The multi-blade fan storage portion 60 and the air duct forming portion 70 are arranged at a position rearward of the front surface of the flat plate portion of the bracket 5, so that the air is sent out from the air outlet 12b of the multi-blade fan 4 to the rear and left direction of the front surface of the flat plate portion of the bracket 5.

[0148] The air duct forming portion 70 forms at least a portion of the air duct 8 that conveys the air sent out from the air outlet 12b of the multi-blade fan 4. In the present embodiment, the air duct forming portion 70 covers the front surface with the bracket cover 6 and forms the air duct 8 together with the bracket cover 6. The air duct forming portion 70 extends from the air outlet 12b of the multi-blade fan 4 in the air delivery direction. The air duct forming portion 70 has a branching portion 71. The air conveyed in the air duct forming portion 70 is branched by the branching portion 71. The air duct forming portion 70 conveys the air sent out from the air outlet 12b of the multi-blade fan 4 first in a direction substantially the same as the air delivery direction, and then branches by the branching portion 71 and conveys it to the reversing camera 2A and the rear view camera 2B, respectively.

[0149] The air duct forming portion 70 is arranged at a position behind the front surface of the flat plate portion of the bracket 5. Therefore, the air duct 8 is arranged behind the front surface of the flat plate portion of the bracket 5, and the air is transported to the rear and leftward of the front surface of the flat plate portion of the bracket 5 by the air duct 8.

[0150] It should be noted that the air duct 8 is formed by the air duct forming portion 70 and the bracket cover 6. However, for example, the portion of the front surface of the flat plate portion of the bracket 5 corresponding to the air duct forming portion 70 may not be opened, and the air duct 8 may be formed only by the air duct forming portion 70. The detailed structure of the air duct 8 will be described later.

[0151] The bracket 5 also has a vehicle body mounting portion 53. The vehicle body mounting portion 53 is provided at both ends of the bracket 5 in the left and right directions. Figure 2 As shown, the vehicle body mounting portion 53 is mounted to the outer panel of the vehicle V in such a manner that the front surface of the flat plate portion of the bracket 5 faces downward.

[0152] [Bracket cover 6]

[0153] Next, the main reference Figure 4A and Figure 4B The bracket cover 6 will be described.

[0154] The bracket cover 6 is configured to cover a portion of the front surface of the bracket 5. In the present embodiment, the bracket cover 6 covers the multi-blade fan storage portion 60 and the air duct forming portion 70. The bracket cover 6 is mounted on the front surface of the flat plate portion of the bracket 5 by a fastening device. The bracket cover 6 includes a first cover portion 6a and a second cover portion 6b. The first cover portion 6a covers the front surface of the multi-blade fan storage portion 60. The first cover portion 6a includes a cutout 6c that communicates with the drainage passage 60c of the bracket 5. The cutout 6c is an example of a drainage hole of the bracket. Water discharged from the drainage port 12c of the multi-blade fan 4 is discharged from the cutout 6c of the bracket cover 6 via the drainage passage 60c of the bracket 5. In addition, the first cover portion 6a includes an opening 6d corresponding to the air intake port 12a of the multi-blade fan 4. The multi-blade fan 4 takes in external air from the air intake port 12a via the opening 6d of the first cover portion 6a.

[0155] The second cover portion 6b covers the front surface of the air duct forming portion 70, and forms the air duct 8 together with the air duct forming portion 70 of the bracket 5. It should be noted that the bracket cover 6 has the second cover portion 6b. However, when the air duct 8 is formed only by the air duct forming portion 70, the bracket cover 6 may also have only the first cover portion 6a.

[0156] [Nozzle 9]

[0157] The nozzle 9 is configured to spray cleaning fluid and / or air toward the vehicle-mounted camera 2. Figure 4B As shown, the nozzle 9 is integrally formed with the second cover portion 6b of the bracket cover 6. In the present embodiment, the nozzle 9 has a nozzle 9A for a reversing camera and a nozzle 9B for a rear view camera. The air sent out from the multi-blade blower 4 is transported to the nozzle 9A for the reversing camera and the nozzle 9B for the rear view camera via the air duct 8. The air transported to the nozzle 9A for the reversing camera and the nozzle 9B for the rear view camera is sprayed from the front ends of the nozzle 9A for the reversing camera and the nozzle 9B for the rear view camera toward the reversing camera 2A and the rear view camera 2B. In addition, the cleaning fluid transported from the box 100 via the connecting hose 103 is sprayed from the front ends of the nozzle 9A for the reversing camera and the nozzle 9B for the rear view camera toward the reversing camera 2A and the rear view camera 2B.

[0158] It should be noted that the nozzle 9 is integrally formed with the bracket cover 6. However, for example, the nozzle 9 may be formed separately from the bracket cover 6 and integrated by assembling or bonding to the bracket cover 6. In addition, when the air duct 8 is formed by using the air duct forming portion 70, the nozzle 9 may be formed integrally with the bracket 5. It should be noted that integrally forming includes integrally forming, or separately forming and integrating by assembling or bonding. The detailed structure of the nozzle 9 will be described later.

[0159] As described above, in the present embodiment, the bracket 5 includes the camera mounting portion 50 and the air duct forming portion 70. Therefore, it is possible to prevent the air duct 8 from being misaligned with respect to the vehicle-mounted camera 2 with a simple structure.

[0160] The camera mounting portion 50 includes a backup camera mounting portion 50A and a rear view camera mounting portion 50B. The air duct forming portion 70 includes a branching portion 71 that branches the air duct forming portion 70 into two portions. Therefore, air can be supplied to each of the backup camera 2A and the rear view camera 2B.

[0161] In addition, bracket 5 includes multi-blade fan housing portion 60 communicating with air guide duct forming portion 70. Therefore, it is possible to prevent multi-blade fan 4 from being displaced relative to air guide duct 8 with a simple structure.

[0162] In addition, the multi-blade fan storage portion 60, the reversing camera mounting portion 50A, and the rear view camera mounting portion 50B are arranged in this order, and the air duct forming portion 70 extends from the multi-blade fan storage portion 60 along the arrangement direction of the reversing camera mounting portion 50A and the rear view camera mounting portion 50B. The air from the multi-blade fan 4 is transported along the arrangement direction of the reversing camera mounting portion 50A and the rear view camera mounting portion 50B by the air duct forming portion 70. Therefore, it is easy to smoothly circulate air to the rear view camera mounting portion 50B located farther from the storage portion of the multi-blade fan 4. Therefore, more air from the multi-blade fan 4 can be transported to the rear view camera 2B.

[0163] The bracket cover 6 forms a part of the air duct 8, and forms the air duct 8 together with the air duct forming portion 70 of the bracket 5. The nozzle 9 is integrally formed with the bracket cover 6. Therefore, the nozzle 9 can be prevented from being misaligned with respect to the air duct 8 with a simple structure.

[0164] In addition, the bracket 5 has a drainage passage 60c communicating with the drainage port 12c of the multiblade fan 4. The bracket cover 6 has a cutout 6c communicating with the drainage passage 60c of the bracket 5. Therefore, water entering from the inlet of the multiblade fan 4 can be discharged to the outside.

[0165] In addition, by using the bracket 5 having the above-mentioned structure, the vehicle-mounted camera 2 is arranged at a position forward of the front surface of the flat plate portion of the bracket 5. The multi-blade fan 4 is arranged at a position rearward of the front surface of the flat plate portion of the bracket 5. The air outlet 12b of the multi-blade fan 4 sends air to the rear of the front surface of the flat plate portion of the bracket 5 and to the left of the bracket 5. Therefore, the vehicle-mounted camera 2 is arranged so as not to overlap with the air outlet 12b of the multi-blade fan 4 in the air outlet direction of the air outlet 12b of the multi-blade fan 4. Therefore, the air flow from the multi-blade fan 4 to the vehicle-mounted camera 2 becomes good.

[0166] In addition, with the bracket 5 having the above-described structure, the air duct 8 is arranged at a position rearward of the front surface of the flat plate portion of the bracket 5. The air duct 8 extends from the air outlet 12b of the multi-blade fan 4 in the air outlet direction. Therefore, the air duct 8 is arranged so as not to overlap with the vehicle-mounted camera 2 in the air outlet direction of the air outlet 12b of the multi-blade fan 4. Therefore, the air from the multi-blade fan 4 can be smoothly delivered to the vehicle-mounted camera 2.

[0167] In addition, the multi-blade fan 4 and the air duct 8 are located behind the front surface of the flat plate portion of the bracket 5 and do not protrude from the front surface of the flat plate portion of the bracket 5. Therefore, when the bracket 5 is mounted on the outer panel of the vehicle V, the multi-blade fan 4 and the air duct 8 do not protrude forward from the outer panel, and interference with the vehicle-mounted camera 2 can be prevented.

[0168] [Filter 7]

[0169] Next, the main reference Figure 4B and Figure 5 The filter 7 will be described.

[0170] The filter 7 is configured to prevent foreign matter from entering the multi-blade fan 4 from the outside and to allow air to pass through. The filter 7 is detachably disposed on the front side of the air intake port 12a of the multi-blade fan 4. The filter 7 is composed of a porous material and filters air containing foreign matter from the outside. The filter 7 is composed of, for example, polyurethane foam (sponge), non-woven fabric, etc. In this embodiment, Figure 4B As shown in FIG. 1 , the filter 7 has a disc-like shape having a thickness T and is disposed between the bracket cover 6 and the air inlet 12a of the multi-blade fan 4. For example, when the filter 7 is made of sponge, the thickness T is formed to be greater than the distance D ( Figure 5 In this case, the filter 7 is sandwiched between the bracket cover 6 and the air intake port 12a of the multi-blade fan 4 in a compressed state, and finer foreign matter can be filtered.

[0171] Thus, in the present embodiment, the filter 7 is provided at the air intake port 12a of the multi-blade fan 4. Therefore, it is possible to prevent foreign matter from entering the interior of the multi-blade fan 4 from the air intake port 12a. For example, when the multi-blade fan 4 is driven to take in air from the air intake port 12a, it is possible to prevent foreign matter such as garbage from entering the interior of the multi-blade fan 4.

[0172] Furthermore, even if multi-blade fan 4 is used as the air supply unit and more foreign matter is likely to enter multi-blade fan 4 in order to continuously take in air, filter 7 can prevent foreign matter such as garbage from entering the interior of multi-blade fan 4.

[0173] In addition, the filter 7 is detachably provided with respect to the air intake port 12a of the sirocco fan 4. Therefore, when the filter 7 is deteriorated, it can be replaced with a new filter 7.

[0174] In addition, the vehicle cleaner 3 is mounted on the outer panel of the vehicle V, and the air intake port 12a of the multi-blade fan 4 is connected to the outside of the vehicle. The multi-blade fan 4 takes in the air outside the vehicle from the air intake port 12a, and there is a high possibility that more foreign matter enters, but the filter 7 can prevent foreign matter outside the vehicle from entering the interior of the multi-blade fan 4.

[0175] [Air duct 8]

[0176] Next, the main reference Fig. 9 The air guide duct 8 will be described. Fig. 9 yes Figure 3 A cross-sectional view of the vehicle cleaner unit 1 taken along the line IX-IX.

[0177] The air duct 8 is configured to convey air from the multi-blade fan 4 to the reversing camera 2A and the rear view camera 2B. In the present embodiment, the air duct 8 is formed by the air duct forming portion 70 of the bracket 5 and the second cover portion 6b of the bracket cover 6. The air duct 8 is connected to the air outlet 12b of the multi-blade fan 4 accommodated in the multi-blade fan accommodation portion 60. The air duct 8 extends from the air outlet 12b of the multi-blade fan 4 along the air delivery direction A. The air duct 8 has a first opening 8a, a second opening 8b, and an air inlet 8c. The first opening 8a is an opening for delivering air to the reversing camera nozzle 9A. The second opening 8b is an opening for delivering air to the rear view camera nozzle 9B. The first opening 8a and the second opening 8b are formed at positions that do not overlap with the air outlet 12b of the multi-blade fan 4 in the air delivery direction A. The first opening 8a and the second opening 8b open in a direction intersecting the air delivery direction A. The first opening 8a and the second opening 8b are formed by covering the portion of the air duct forming portion 70 of the bracket 5 except for the portion corresponding to the nozzle 9 with the bracket cover 6. The air introduction port 8c is connected to the air outlet 12b of the multi-blade fan 4 and opens in the air delivery direction A. The air from the air outlet 12b of the multi-blade fan 4 is introduced into the air duct 8 through the air introduction port 8c.

[0178] The air duct 8 has a main conveying path 80, a first branch path 81, and a second branch path 82. The first branch path 81 and the second branch path 82 are formed by branching from the main conveying path 80 using the branch portion 71. The main conveying path 80 conveys the air introduced from the air inlet 8c in a direction substantially the same as the air delivery direction A (hereinafter referred to as the air conveying direction B). The first branch path 81 conveys a portion of the air conveyed by the main conveying path 80 and branched by the branch portion 71 to the nozzle 9A for the reversing camera. The second branch path 82 conveys a portion of the air conveyed by the main conveying path 80 and branched by the branch portion 71 to the nozzle 9B for the rearview camera.

[0179] The first branch path 81 extends from the main conveying path 80 at a first angle θ1 relative to the air conveying direction B of the main conveying path 80, and the second branch path 82 extends from the main conveying path 80 at a second angle θ2 relative to the air conveying direction B of the main conveying path 80. By making the first angle θ1 and the second angle θ2 different, different amounts of air can be conveyed to a plurality of cleaning objects. For example, by setting the second angle θ2 smaller than the first angle θ1, the second branch path 82 can convey more air than the first branch path 81.

[0180] The branch portion 71 of the air duct 8 has a partition 71a and a guide plate 71b. The partition 71a constitutes a part of the first branch path 81. The guide plate 71b constitutes a part of the second branch path 82. The partition 71a is arranged in the middle of the air conveying path of the main conveying path 80 along a direction intersecting the air conveying direction B (i.e., the air delivery direction A) relative to the main conveying path 80. The partition 71a is arranged to overlap with a part of the air delivery outlet 12b of the multi-blade fan 4 in the air delivery direction A. The partition 71a extends toward the first opening 8a. A part of the air conveyed in the main conveying path 80 collides with the partition 71a, and the direction in which it is conveyed is changed toward the first opening 8a. The guide plate 71b is connected to the end opposite to the end of the first opening 8a connected to the partition 71a, and extends toward the second opening 8b. In the present embodiment, the partition plate 71a extends from the left edge of the first opening 8a (the edge close to the second branch path 82) toward the main conveying path 80 in a direction perpendicular to the air delivery direction A. The guide plate 71b extends from the portion connected to the partition plate 71a to the right edge of the second opening 8b (the edge close to the first branch path 81) in a direction intersecting the air delivery direction A.

[0181] In addition, the air guide 8 has a first inner surface 83 and a second inner surface 84. The first inner surface 83 is an inner surface connecting the air inlet 8c and the first opening 8a. The first inner surface 83 extends from the air inlet 8c toward the first opening 8a and in a direction intersecting with the air delivery direction A. The second inner surface 84 is an inner surface connecting the air inlet 8c and the second opening 8b. The second inner surface 84 has a first portion 84a and a second portion 84b. The first portion 84a extends from the air inlet 8c along the air delivery direction A. The second portion 84b extends from the first portion 84a to the second opening 8b in a direction intersecting with the air delivery direction A. The second portion 84b extends in the same direction as the guide plate 71b. The first inner surface 83 and the first portion 84a of the second inner surface 84 constitute a portion of the main conveying path 80. The second portion 84b of the second inner surface 84 constitutes a portion of the second branch path 82. In the present embodiment, the first inner surface 83 is constituted by a portion of the rear surface of the bracket cover 6. The second inner surface 84 is formed by the inner surface of the air guide duct forming portion 70 of the bracket 5. It should be noted that the first inner surface 83 may also be formed by the bracket 5.

[0182] like Fig. 9 As shown, the air duct 8 transports the air sent out from the air outlet 12b of the multi-blade fan 4 via the air inlet 8c in the air sending direction A along the air sending direction B of the bracket 5 using the main transport path 80. Then, the air duct 8 branches the air using the branching portion 71, and the branched air is transported using the first branch path 81 and the second branch path 82, and is sent out from the first opening 8a and the second opening 8b.

[0183] Thus, in the present embodiment, the air duct 8 has a partition 71a disposed in a direction intersecting the air delivery direction A in the middle of the air delivery direction A. For example, the partition 71a extends in a direction orthogonal to the air delivery direction A. By using the partition 71a to change the direction of a part of the air, it is possible to transport air to a plurality of cleaning objects (reversing camera 2A and rear view camera 2B) using one air duct 8. Thus, it is possible to transport air to a plurality of cleaning objects using a simple structure.

[0184] In addition, the partition plate 71a overlaps a part of the air outlet 12b of the multiblade fan 4 in the air outlet direction A. Therefore, the direction of a part of the air sent along the air outlet direction A can be changed more effectively by the partition plate 71a.

[0185] In addition, the partition plate 71a extends toward the first opening 8a corresponding to the back-up camera 2A. Therefore, the partition plate 71a can be used to change the direction of a part of the air and guide it toward the first opening 8a corresponding to the back-up camera 2A.

[0186] In addition, the first opening 8a is formed at a position that does not overlap with the air outlet 12b of the multi-blade fan 4 in the air outlet direction A. The air guide duct 8 has a first inner surface 83 that connects the air outlet 12b (air inlet 8c) of the multi-blade fan 4 and the first opening 8a. Therefore, the first inner surface 83 can be used to guide air in the direction of the first opening 8a corresponding to the backup camera 2A.

[0187] In addition, the air guide 8 has a second inner surface 84 that connects the air outlet 12b (air inlet 8c) of the multi-blade fan 4 and the second opening 8b. The second inner surface 84 has a first portion 84a extending from the air outlet 12b of the multi-blade fan 4 along the air delivery direction A, and a second portion 84b extending from the first portion 84a to the second opening 8b. Therefore, the first portion 84a of the second inner surface 84 can be used to transport air along the air delivery direction A, and the second portion 84b can be used to guide air in the direction of the second opening 8b corresponding to the rearview camera 2B.

[0188] The air duct 8 has a guide plate 71b extending from the end of the partition plate 71a opposite to the end connected to the first opening 8a toward the second opening 8b. Therefore, the guide plate 71b can guide air toward the second opening 8b relative to the rear view camera 2B.

[0189] In addition, the air duct 8 delivers different amounts of air to the reversing camera 2A and the rear view camera 2B, respectively. Therefore, each cleaning object can be cleaned with an amount of air corresponding to the function and / or shape of each cleaning object. Thus, a vehicle cleaning unit 1 that can efficiently clean multiple cleaning objects with different functions and / or shapes can be provided.

[0190] In addition, the air duct 8 has a main conveying path 80, a first branch path 81, and a second branch path 82. The first branch path 81 and the second branch path 82 are formed to convey different amounts of air to the reversing camera 2A and the rear view camera 2B, respectively. Therefore, the first branch path 81 and the second branch path 82 can be used to convey an amount of air corresponding to the function and / or shape of each cleaning object.

[0191] In addition, the first branch path 81 extends from the main conveying path 80 at a first angle θ1 relative to the conveying direction of air of the main conveying path 80. The second branch path 82 extends from the main conveying path 80 at a second angle θ2 relative to the air conveying direction B of the main conveying path 80. The second angle θ2 is smaller than the first angle θ1. Therefore, more air flows from the main conveying path 80 to the second branch path 82 than to the first branch path 81, and therefore, the second branch path 82 can convey more air than the first branch path 81.

[0192] In addition, when viewed from a direction perpendicular to the air delivery direction A, the multi-blade fan 4, the backup camera 2A, and the rear view camera 2B are arranged in this order. Therefore, the rear view camera 2B is arranged farther from the multi-blade fan 4 than the backup camera 2A. With this structure, more air flows from the main delivery path 80 to the second branch path 82 than to the first branch path 81, so the second branch path 82 can deliver more air than the first branch path 81.

[0193] In addition, the first branch path 81 is formed to supply air to the reversing camera 2A. The second branch path 82 is formed to supply air to the rear view camera 2B. Therefore, it is possible to perform cleaning with an amount of air corresponding to the functions of the reversing camera 2A and the rear view camera 2B. The reversing camera 2A obtains an image near the vehicle V when reversing. The rear view camera 2B always obtains an image behind the vehicle V. For example, by supplying more air to the rear view camera 2B than to the reversing camera 2A, the rear view camera 2B can prevent foreign matter from adhering and always obtain a good image.

[0194] [Structure of the nozzle 9]

[0195] Next, refer to Figure 10 to Figure 15B The structure of the nozzle 9 will be described. Fig.10 It is a perspective view showing the vehicle washer unit 1 to which the connection hose 103 is connected. Fig.11 yes Figure 3 A cross-sectional view of the vehicle cleaner unit 1 taken along the line XI-XI. Fig. 12A yes Figure 2 XIIA-XII cross-sectional view of the vehicle cleaner unit 1 .

Fig. 13B 1 is a diagram showing an injection port of a nozzle for a rear view camera, and is a diagram showing the injection port of the nozzle for a rear view camera as seen from below. Fig.14A 2B is a diagram showing a rear view camera and a nozzle for the rear view camera, and is a diagram viewed from the front of the rear view camera 2B. Fig. 14B 1 and 2 . The figure shows a rear view camera and a nozzle for the rear view camera, and is a figure showing the rear view camera 2B as seen from an oblique angle. Fig.15A It is a diagram showing a nozzle for a rear view camera according to a first modification. Fig. 15B1 is a diagram showing a nozzle for a rear view camera of Modification 2. It should be noted that the same reference numerals are used for the common components of the nozzle for a rear view camera 9A and the nozzle for a rear view camera 9B, and finally, "A" is marked for the components of the nozzle for a rear view camera 9A, and "B" is marked for the components of the nozzle for a rear view camera 9B.

[0196] like Fig.10 As shown, the nozzle 9 is connected to the air duct 8, conveys air from the air duct 8, and sprays from the front end to the vehicle-mounted camera 2 as the cleaning object. The nozzle 9 has a cleaning liquid introduction path 90 connected to the connecting hose 103. The nozzle 9 sprays the cleaning liquid conveyed through the connecting hose 103 and the cleaning liquid introduction path 90 from the front end to the vehicle-mounted camera 2 as the cleaning object. The connecting hose 103 is led back to the front side of the bracket 5 from the back side of the bracket 5 through a through hole (not shown). In this embodiment, the nozzle 9 has a reversing camera nozzle 9A for spraying to the reversing camera 2A and a rear view camera nozzle 9B for spraying to the rear view camera 2B. It should be noted that in the following description, the common structure of the reversing camera nozzle 9A and the rear view camera nozzle 9B is described as the structure of the nozzle 9, and the description of the respective structures of the reversing camera nozzle 9A and the rear view camera nozzle 9B is omitted.

[0197] <Straight portion 91 of nozzle 9>

[0198] like Fig.11 As shown, the nozzle 9 extends from the air guide duct 8 in a direction (hereinafter referred to as the nozzle extension direction C) intersecting the air conveying direction B. In this embodiment, the nozzle extension direction C is orthogonal to the air conveying direction B.

[0199] like Figure 10 to Figure 12B As shown, the nozzle 9 has a straight portion 91 and a front end portion 92. The straight portion 91 is connected to the air duct 8 and extends linearly from the air duct 8 along a direction intersecting the air conveying direction B (nozzle extension direction C). Fig. 12A and Fig. 12B As shown, the straight portion 91 extends from the air duct 8 to the lens 2a of the vehicle-mounted camera 2. The reversing camera 2A and the rear view camera 2B are installed at different positions and directions relative to the air duct 8, so the reversing camera nozzle 9A and the rear view camera nozzle 9B extend in different directions. Fig. 12A As shown in FIG. 1 , the straight portion 91A of the backup camera nozzle 9A extends in a direction substantially the same as the long side direction of the frame of the backup camera 2A. Fig. 12BAs shown, the straight portion 91B of the rear view camera nozzle 9B extends slightly obliquely with respect to the longitudinal direction of the housing of the rear view camera 2B. The straight portion 91B extends so as to approach the housing of the rear view camera 2B as it approaches the lens 2Ba of the rear view camera 2B.

[0200] The front end portion 92 sprays cleaning fluid or air from the front end of the opening toward the vehicle-mounted camera 2. The front end portion 92 extends from the front end of the straight portion 91 in a direction toward the lens 2a of the vehicle-mounted camera 2. Fig.14A ) is perpendicular to the nozzle extension direction C.

[0201] like Fig.11 As shown, the nozzle extension direction C of the nozzle is the same as the arrangement direction of the partition 71a of the air duct 8. The straight portion 91 guides and transports the air sent out from the air duct 8 in a manner that the air that collides with the partition 71a and changes direction is transported along the arrangement direction of the partition 71a. In this embodiment, the straight portion 91 guides and transports the air sent out from the air duct 8 along a direction (nozzle extension direction C) orthogonal to the air transport direction B.

[0202] Thus, in the present embodiment, the straight portion 91 of the nozzle 9 extends along a direction (nozzle extension direction C) that intersects the air delivery direction B and is orthogonal to the width direction E of the front end portion 92 of the nozzle 9. The straight portion 91 guides the air from the air duct 8 along the nozzle extension direction C. Therefore, the straight portion 91 of the nozzle 9 can be used to change the direction of the air from the air delivery direction B to the nozzle extension direction C. For example, even if the cleaning surface of the cleaning object (for example, the lens 2a of the vehicle-mounted camera 2) is located in a position that does not overlap with the multi-blade fan 4 in the air delivery direction A, the nozzle 9 can be used to change the direction of the air to the cleaning surface of the cleaning object and transport it. Therefore, air can be ejected from the nozzle 9 in a desired direction.

[0203] In addition, in this embodiment, the nozzle extension direction C is orthogonal to the air conveying direction B. Therefore, for example, even if the cleaning object having a cleaning surface at the front end extends in a direction orthogonal to the air conveying direction B, the nozzle 9 can be used to change the direction of the air to the direction in which the cleaning object extends and convey it.

[0204] It should be noted that the structure of the nozzle 9 having the straight portion 91 can also be applied to a nozzle that only ejects air. Even in the case of a nozzle that only ejects air, the same effects as described above can be obtained.

[0205] <Gas-Liquid Structure of Nozzle 9>

[0206] like Fig.10 and Fig.11As shown, the nozzle 9 has a partition 96 at least at the front end 92 at a position approximately in the center of the width direction of the nozzle 9. The backup camera nozzle 9A has a partition 96A at a position approximately in the center of the width direction of the backup camera nozzle 9A, which extends from the middle of the straight portion 91A to the front end 92A. The rear view camera nozzle 9B has a partition 96B at the front end 92B at a position approximately in the center of the width direction of the rear view camera nozzle 9B. Air delivery paths 97, 97 are formed on both sides of the partition 96, and a cleaning liquid delivery path 98 is formed inside the partition 96.

[0207] like Figures 12A to 13B As shown, the air delivery paths 97, 97 are connected to the air injection ports 95, 95 respectively, and the cleaning liquid delivery path 98 is connected to the cleaning liquid injection port 94 via the cleaning liquid injection path 99. The cleaning liquid injection port 94 and the air injection ports 95, 95 are formed at the front end of the front end portion 92 of the nozzle 9. The cleaning liquid injection port 94 and the air injection ports 95, 95 are formed as independent individual injection ports by using the dividing portion 96.

[0208] The air conveyed in the nozzle 9 is branched by the dividing portion 96 and conveyed through the air conveying paths 97, 97. The air conveyed through the air conveying paths 97, 97 is ejected from the air ejection ports 95, 95.

[0209] like Fig. 12A and Fig. 12B As shown, the cleaning liquid delivery path 98 is connected to the cleaning liquid introduction path 90. In addition, the front end 98a of the cleaning liquid delivery path 98 is formed in a reduced diameter manner. The front end 98a of the cleaning liquid delivery path 98 and the cleaning liquid injection port 94 are connected by the cleaning liquid injection path 99. The cleaning liquid injection path 99 is formed so as to become wider as it approaches the cleaning liquid injection port 94. The cleaning liquid introduced from the cleaning liquid introduction path 90 is delivered by the cleaning liquid delivery path 98, and pressure is applied to the front end 98a of the cleaning liquid delivery path 98, and is ejected from the cleaning liquid injection port 94 via the cleaning liquid injection path 99.

[0210] like Fig.13A and Fig. 13B As shown, the air injection ports 95, 95 are arranged on both sides of the cleaning liquid injection port 94 in the width direction E of the front end portion 92 of the nozzle 9. The cleaning liquid injection port 94 is used to inject cleaning liquid from the center of the front end of the nozzle 9, and the air injection ports 95, 95 are used to inject air from both ends of the front end of the nozzle 9.

[0211] The shapes of the air injection ports 95, 95 and the shape of the cleaning liquid injection port 94 are different from each other. Fig.13A and Fig. 13BAs shown, the width of the air injection ports 95, 95 in the direction perpendicular to the width direction E of the front end portion 92 is set to W1, and the width of the direction parallel to the width direction E of the front end portion 92 is set to W3. In addition, the width of the cleaning liquid injection port 94 in the direction perpendicular to the width direction E of the front end portion 92 is set to W2, and the width of the direction parallel to the width direction E of the front end portion 92 is set to W4. In this embodiment, the width W1 of the air injection ports 95, 95 is wider than the width W2 of the cleaning liquid injection port 94. In addition, the width W3 of the air injection ports 95, 95 is wider than the width W4 of the cleaning liquid injection port 94. In addition, the area of ​​the surface of the air injection ports 95, 95 orthogonal to the injection direction of the air is larger than the area of ​​the surface of the cleaning liquid injection port 94 perpendicular to the injection direction of the cleaning liquid.

[0212] It should be noted that the widths W1 and W3 of the air injection ports 95, 95 are set wider than the widths W2 and W4 of the cleaning liquid injection port 94. However, either the widths W1 and W3 of the air injection ports 95, 95 may be set wider than the corresponding widths W2 and W4 of the cleaning liquid injection port 94.

[0213] In addition, the widths W1 and W3 of the air injection ports 95 and 95 are set wider than the widths W2 and W4 of the cleaning liquid injection port 94, so the areas of the air injection ports 95 and 95 become larger than the area of ​​the cleaning liquid injection port 94. However, for example, the air injection ports 95 and 95 and the cleaning liquid injection port 94 may be formed in such a manner that the areas of the air injection ports 95 and 95 become larger than the area of ​​the cleaning liquid injection port 94 regardless of the widths W1 and W3 of the air injection ports 95 and 95 and the widths W2 and W4 of the cleaning liquid injection port 94.

[0214] Thus, in the present embodiment, the air injection ports 95, 95 are arranged on both sides of the cleaning liquid injection port 94. Therefore, water droplets or foreign matter attached to the front end of the nozzle 9 can be removed by the air injected from the air injection ports 95, 95. For example, water droplets or foreign matter attached to the front end of the nozzle 9 and water droplets or foreign matter attached to the cleaning liquid injection port 94 can be removed by the air injected from the air injection ports 95, 95. The water droplets are, for example, water droplets of residual cleaning liquid or rainwater. In addition, since the air injection ports 95, 95 and the cleaning liquid injection port 94 are formed in one nozzle 9, the appearance of the vehicle cleaner 3 is improved compared with the case where a plurality of nozzles are independently provided for both air and liquid.

[0215] The width W1 of the air injection ports 95, 95 is wider than the width W2 of the cleaning liquid injection port 94. Therefore, the air injection ports 95, 95 can inject air without hindering the flow of air. On the other hand, the cleaning liquid injection port 94 can inject the cleaning liquid while spreading it widely.

[0216] The width W3 of the air injection ports 95, 95 is wider than the width W4 of the cleaning liquid injection port 94. Therefore, the air injection ports 95, 95 can inject air without hindering the flow of air. On the other hand, the cleaning liquid injection port 94 can inject the cleaning liquid while spreading it widely.

[0217] In addition, the area of ​​the surface of the air injection ports 95, 95 perpendicular to the injection direction of the air is larger than the area of ​​the surface of the cleaning liquid injection port 94 perpendicular to the injection direction of the cleaning liquid. Therefore, the air injection ports 95, 95 can inject air without hindering the flow of air. On the other hand, the cleaning liquid injection port 94 can inject while spreading the cleaning liquid widely.

[0218] <Tip shape of nozzle 9>

[0219] The front end of the nozzle 9 is formed so that at least one end in the width direction thereof extends toward the downstream side of the injection direction relative to the central portion. Fig.14A and Fig. 14B As shown, the front end of the nozzle 9 is formed such that both ends 9e, 9e of the front end portion 92 in the width direction E extend downstream of the center portion 9c in the ejection direction G. The front end of the nozzle 9 extends downstream in the ejection direction G while bending from the center portion 9c to the ends 9e.

[0220] It should be noted that the front end of the nozzle 9 is not limited to a curved shape. Fig.15A As shown in FIG. 1 , the nozzle 9 may linearly extend from the central portion 9c to the end portions 9e, 9e to the downstream side of the injection direction G. In addition, the end portions 9e, 9e of the front end of the nozzle 9 in the width direction E extend to the downstream side of the injection direction G relative to the central portion 9c. However, for example, Fig. 15B As shown, it may extend toward the downstream side while being inclined with respect to the injection direction G from one end portion 9e to the other end portion 9e.

[0221] like Fig. 14B As shown, both ends 9e, 9e of the nozzle 9 have contact portions 9a, 9a respectively in contact with the vehicle-mounted camera 2. In this embodiment, the contact portions 9a, 9a not only extend over the front end of the nozzle 9, but also extend over the front end 92 to contact with the vehicle-mounted camera 2. It should be noted that the contact portions 9a, 9a extend over not only the front end of the nozzle 9, but also extend over the front end 92 to contact with the vehicle-mounted camera 2, but at least part of the front end of the nozzle 9 is sufficient.

[0222] The width W5 of the front end of the nozzle 9 is set larger than the width W6 of the cleaning surface (for example, the lens 2 a ) of the vehicle-mounted camera 2 .

[0223] It should be noted that Figures 14A to 15BIn the figure, the vehicle-mounted camera 2 and the nozzle 9 are shown as the structure of the rear-view camera 2B and the nozzle 9B for the rear-view camera, but the backup camera 2A and the nozzle 9A for the backup camera have the same structure. In the case where the vehicle cleaner 3 has a plurality of nozzles 9, the front ends of the plurality of nozzles 9 may have mutually different shapes. That is, the front ends of the nozzle 9A for the backup camera and the nozzle 9B for the rear-view camera may also have mutually different shapes. For example, the front ends of the nozzle 9A for the backup camera and the nozzle 9B for the rear-view camera have Fig.14A The shape of the nozzle 9A for the rearview camera may be different in length in the injection direction and / or in the width direction between the center and the end, or in the degree of curvature from the center to the end. Fig.14A The front end of the rear view camera nozzle 9B has a shape similar to Fig.14A Different shapes, such as Fig.15A shape.

[0224] Thus, in the present embodiment, one end 9e of the front end of the nozzle 9 in the width direction E extends to the downstream side of the central portion 9c in the spraying direction G. Therefore, water droplets attached to the central portion 9c of the front end of the nozzle 9 flow toward the end, thereby preventing the water droplets attached to the front end of the nozzle 9 from being detected by the vehicle-mounted camera 2 (an example of the detection surface of the vehicle-mounted sensor).

[0225] In addition, both end portions 9e, 9e of the front end of the nozzle 9 in the width direction E extend downstream of the central portion 9c in the ejection direction. Therefore, water droplets attached to the central portion 9c of the front end of the nozzle 9 flow toward both end portions 9e, 9e, thereby preventing the water droplets attached to the front end of the nozzle 9 from being reflected on the vehicle-mounted camera 2.

[0226] In addition, the end of the front end of the nozzle 9 has a contact portion 9a that contacts the vehicle-mounted camera 2. Therefore, water drops attached to the central portion of the front end of the nozzle 9 flow toward the vehicle-mounted camera 2 via the contact portion 9a at the end, thereby preventing water drops from falling from the end of the front end of the nozzle 9.

[0227] In addition, the front end of the nozzle 9 is bent from the central portion 9c to the end portion 9e and extends toward the downstream side of the spraying direction. Therefore, the water droplets attached to the central portion 9c of the front end of the nozzle 9 flow smoothly toward the end portion 9e, thereby preventing the water droplets attached to the front end of the nozzle 9 from being detected by the vehicle-mounted camera 2.

[0228] In addition, the vehicle cleaner 3 includes a plurality of nozzles 9, and the front ends of the plurality of nozzles 9 have mutually different shapes. Therefore, it is possible to use nozzles 9 having front ends with different shapes according to the shapes and directions of the cleaning surfaces of the plurality of vehicle-mounted cameras 2. For example, the front end of the nozzle 9 has different lengths in the spraying direction of the central portion and the end portions, different lengths in the width direction of the central portion and the end portions, or different degrees of bending from the central portion to the end portions. Therefore, it is possible to efficiently flow water droplets attached to the central portion of the front end of the nozzle 9 toward the end portions according to the shapes and directions of the cleaning surfaces of the plurality of vehicle-mounted cameras 2.

[0229] In addition, the nozzle 9 sprays the washer fluid and the air toward the lens 2a of the vehicle-mounted camera 2. Therefore, it is possible to prevent the washer fluid remaining at the tip of the nozzle 9 after spraying the washer fluid from being detected by the vehicle-mounted camera 2.

[0230] In addition, the width of the front end of the nozzle 9 is larger than the width of the cleaning surface (for example, the lens 2a) of the vehicle-mounted camera 2. Therefore, the water droplets attached to the central portion 9c of the front end of the nozzle 9 flow toward the end portion 9e, thereby more reliably preventing the water droplets attached to the front end of the nozzle 9 from being detected by the vehicle-mounted camera 2.

[0231] It should be noted that the tip shape of the nozzle 9 can also be applied to a nozzle that only sprays air or a nozzle that only sprays cleaning fluid. Even in the case of a nozzle that only sprays air or a nozzle that only sprays cleaning fluid, the same effect as described above can be obtained.

[0232] (Second Embodiment)

[0233] Next, a vehicle cleaner 203 according to a second embodiment will be described with reference to the drawings. Fig.16 It is a front view showing a vehicle cleaner unit 201 according to the second embodiment. In the description of the second embodiment, components having the same reference numerals as those already described in the description of the first embodiment will be omitted for convenience of description.

[0234] The vehicle cleaner unit 201 of the second embodiment is different from the first embodiment in that it has a heat wire 204 provided around the air intake port 12a of the multi-blade fan 4. It should be noted that the structure of the vehicle cleaner unit 201 other than the heat wire 204 is the same as that of the first embodiment, and its description is omitted for convenience of description.

[0235] The heat wire 204 is an example of a heating unit. The heat wire 204 is provided on the front surface of the bracket cover 6 so as to surround the periphery of the opening 6d of the bracket cover 6. The heat wire 204 extends upward from the periphery of the opening 6d of the bracket cover 6, and is led back to the back side of the bracket 5, and is connected to a predetermined heat source (not shown) in the vehicle. The heat wire 204 heats the periphery of the air intake port 12a of the multi-blade fan 4 by the heat transmitted from the heat source.

[0236] Thus, in the above-mentioned embodiment, the periphery of the air inlet 12a of the multi-blade fan 4 is heated by the heat wire 204 provided around the air inlet 12a of the multi-blade fan 4. Therefore, it is possible to prevent snow from being blown up during snowfall or snow accumulated on the road surface and adhering to the air inlet 12a of the multi-blade fan 4 or its periphery. In addition, it is also possible to prevent water droplets adhering to the air inlet 12a of the multi-blade fan 4 or its periphery from freezing.

[0237] It should be noted that in the above embodiment, the heating wire 204 is disposed on the front surface of the bracket cover 6. However, for example, the heating wire 204 may be disposed on the rear surface of the bracket cover 6. The heating wire 204 may be disposed on other components instead of the bracket cover 6.

[0238] In addition, other devices that heat the periphery of the air intake port 12a of the multi-blade fan 4 may be used instead of the heat wire 204. For example, air may be branched from the air guide duct 8 and the branched air may be blown toward the opening 6d of the bracket cover 6 and its periphery, or toward the air intake port 12a of the multi-blade fan 4 and its periphery. In these cases, it is possible to prevent the adhesion of snow to the air intake port 12a of the multi-blade fan 4 and the freezing of attached water droplets or the like.

[0239] (Third Embodiment)

[0240] Next, a vehicle cleaner unit 301 according to a third embodiment will be described with reference to the drawings. Fig.17 1 is a diagram showing a vehicle-mounted camera 302 and a nozzle 309 of a vehicle washer unit 301 according to a third embodiment. Fig.18 Yes means Fig.17 FIG. 3 is a diagram showing the ejection port of the nozzle 309. It should be noted that, in the description of the third embodiment, for components having the same reference numerals as those already described in the description of the first embodiment, description thereof will be omitted for the sake of convenience.

[0241] In the vehicle cleaner unit 301 of the third embodiment, the cleaning surface of the rear view camera 302B and the cleaning surface of the back-up camera 302A have different sizes from each other, and the back-up camera nozzle 309A and the rear view camera nozzle 309B have different shapes from each other, which is different from the first embodiment. In this embodiment, the cleaning surface is the lens 302Aa, 302Ba, and the lens 302Ba is formed smaller than the lens 302Aa. It should be noted that in the vehicle cleaner unit 301, the structure other than the back-up camera 302A, the rear view camera 302B, the back-up camera nozzle 309A and the rear view camera nozzle 309B is the same as the first embodiment, and its description is omitted for the sake of convenience.

[0242] like Fig.17 As shown, the reversing camera 302A has a circular lens 302Aa. The rear-view camera 302B has a circular lens 302Ba. The lens 302Ba of the rear-view camera 302B has a diameter smaller than the diameter of the lens 302Aa of the reversing camera 302A. That is, the width of the lens 302Ba of the rear-view camera 302B is formed to be smaller than the width of the lens 302Aa of the reversing camera 302A. It should be noted that the width of the lens 302Ba and the lens 302Aa is the width in the direction orthogonal to the spray direction of the cleaning fluid and the air (hereinafter referred to as the spray direction), which is equivalent to the lens diameter in the present embodiment.

[0243] The rear view camera nozzle 309B corresponds to the shape of the lens 302Ba and is formed to be smaller than the reverse camera nozzle 309A. Fig.17 As shown, the width W7 of the rear view camera nozzle 309B in the direction perpendicular to the spraying direction is smaller than the width W8 of the lens 302Aa of the backup camera 302A in the direction perpendicular to the spraying direction.

[0244] In addition, the washer fluid injection port 394B of the rear view camera nozzle 309B is formed so that the injection angle of the washer fluid is smaller than the injection angle of the washer fluid injection port 394A of the backup camera nozzle 309A. Fig.17 As shown, the angle θ3 is formed to be smaller than the angle θ4. The angle θ3 is the expansion angle of the cleaning liquid injection path 399B of the rear view camera nozzle 309B from the front end 398Ba of the cleaning liquid delivery path to the cleaning liquid injection port 394B. The angle θ4 is the expansion angle of the cleaning liquid injection path 399A of the backup camera nozzle 309A from the front end 398Aa of the cleaning liquid delivery path to the cleaning liquid injection port 394A. In addition, as Fig.18 As shown, the width W9 of the washer fluid injection port 394B of the rear view camera nozzle 309B may be formed to be smaller than the width W10 of the washer fluid injection port 394A of the backup camera nozzle 309A.

[0245] In addition, if Fig.18 As shown, the washer fluid injection port 394B of the rear view camera nozzle 309B is formed so that the area of ​​the surface perpendicular to the injection direction of the washer fluid is smaller than the area of ​​the washer fluid injection port 394A of the backup camera nozzle 309A.

[0246] The air ejection ports 395B, 395B of the rear view camera nozzle 309B are formed so that the area of ​​the surface perpendicular to the ejection direction of the washer fluid is smaller than the area of ​​the air ejection ports 395A, 395A of the backup camera nozzle 309A.

[0247] In addition, as described in the first embodiment, the backup camera 302A and the rear view camera 302B are mounted on the bracket 5 in a manner facing different directions. That is, the distance between the lens 302Ba of the rear view camera 302B and the air duct 8 is closer than the distance between the lens 302Aa of the backup camera 302A and the air duct 8. In accordance with this structure, the length of the nozzle 309B for the rear view camera in the injection direction is formed to be smaller than the length of the nozzle 309A for the backup camera in the injection direction.

[0248] It should be noted that the cleaning surface is the lens 302a of the vehicle-mounted camera 302. However, for example, the cleaning surface may be an area including the lens 302a of the vehicle-mounted camera 302 and its surroundings.

[0249] In addition, as an example in which the shape of the rear view camera nozzle 309B is smaller than the shape of the reverse camera nozzle 309A, the width and length of the rear view camera nozzle 309B are reduced compared to the width and length of the reverse camera nozzle 309A. In addition, the spray angle of the washer fluid of the washer fluid injection port 394B of the rear view camera nozzle 309B is made smaller than the spray angle of the washer fluid of the reverse camera nozzle 309A. In addition, the area of ​​the washer fluid injection port 394B and the air injection ports 395B, 395B of the rear view camera nozzle 309B is made smaller than the area of ​​the washer fluid injection port 394A and the air injection ports 395A, 395A of the reverse camera nozzle 309A. However, at least one of them may be formed smaller than the reverse camera nozzle 309A.

[0250] For example, the area of ​​any one of the washer fluid injection port 394B and the air injection port 395B, 395B of the rear view camera nozzle 309B may be smaller than the area of ​​the corresponding washer fluid injection port 394A or the air injection port 395A, 395A of the backup camera nozzle 309A.

[0251] Thus, in the above-mentioned embodiment, the nozzle 309A for the back-up camera and the nozzle 309B for the rear-view camera have different shapes according to the sizes of the back-up camera 302A and the rear-view camera 302B having different sizes of the cleaning surface (e.g., the lens 302Aa, 302Ba). Therefore, the back-up camera 302A and the rear-view camera 302B having different sizes of the cleaning surface can be cleaned efficiently.

[0252] For example, the widths of the backup camera nozzle 309A and the rear view camera nozzle 309B in the direction perpendicular to the spraying direction are different, so that the backup camera 302A and the rear view camera 302B having different cleaning surfaces can be cleaned efficiently.

[0253] In addition, the lengths of the spraying directions of the backup camera nozzle 309A and the rear view camera nozzle 309B are different, so that the backup camera 302A and the rear view camera 302B having different positions and angles of the washing surfaces can be efficiently washed.

[0254] In addition, the spray angles of the washer fluid of the backup camera nozzle 309A and the rear view camera nozzle 309B are different, so the backup camera 302A and the rear view camera 302B having different washing surface sizes can be efficiently washed at different washer fluid spray angles.

[0255] In addition, the areas of the surfaces orthogonal to the spraying directions of the cleaning liquid spraying ports 394 and / or the air spraying ports 395, 395 are different for the backup camera nozzle 309A and the rear view camera nozzle 309B. Therefore, the backup camera 302A and the rear view camera 302B having different sizes of the washing surfaces can be efficiently washed with different spraying angles of the cleaning liquid and / or different spraying amounts of the air.

[0256] In addition, the plurality of cleaning objects are the back-up camera 302A and the rear-view camera 302B. The vehicle cleaner unit 301 can efficiently clean the back-up camera 302A and the rear-view camera 302B. For example, the cleaning surface of the rear-view camera 302B is smaller than the cleaning surface of the back-up camera 302A. Therefore, by making the size (width and / or length, shape of the jet port, etc.) of the rear-view camera nozzle 309B smaller than the size of the back-up camera nozzle 309A, the back-up camera 302A and the rear-view camera 302B can be efficiently cleaned.

[0257] It should be noted that the shape of the nozzle 9 can also be applied to a nozzle that only sprays air or a nozzle that only sprays cleaning liquid. Even in the case of a nozzle that only sprays air or a nozzle that only sprays cleaning liquid, the same effect as described above can be obtained.

[0258] In addition, this embodiment can also be applied to any of the first embodiment and the second embodiment.

[0259] (Variation of multi-blade fan)

[0260] In the first to third embodiments described above, a multi-blade fan having a vibration-proof part composed of an elastic member, an elastic member mounting part, and a retaining frame part is described, but the vibration-proof part is not limited to this structure. For example, the vibration-proof part may also be composed of a leaf spring or the like. Hereinafter, a modified example of a multi-blade fan using a leaf spring is described with reference to the accompanying drawings.

[0261] Fig.19 It is a perspective view of a multi-blade fan 104 according to a modified example. Fig. 20 It is an exploded perspective view of a multi-blade fan 104 according to a modified example. Fig.21 It is a diagram for explaining the connection relationship between the support portion 113 and the holder portion 133 of the multi-blade fan 104 according to the modified example. Fig.22A It is an axial cross-sectional view of a multi-blade fan 104 according to a modified example. Fig. 22B 1 is an axial cross-sectional view of a multi-blade fan 104 of a modified example. It should be noted that: Fig.22A It is a cross-sectional view of a portion including a support portion mounting portion 137 (hereinafter referred to as mounting portion 137 ) of the holder portion 133 cut along the rotation axis Ax. Fig. 22B It is a cross-sectional view of a portion of the first leaf spring 135A including the holder portion 133 cut along the rotation axis Ax. Fig.22A and Fig. 22B In FIG. 1 , only the housing 112 and the holder portion 133 are shown in cross section. Fig.23A It is a diagram showing a holder portion 133 of a multi-blade fan 104 according to a modified example. Fig. 23B The figure shows a holder 133 mounted on a motor 121 of a multiblade fan 104 of a modified example. It should be noted that in the description of the multiblade fan 104, the description of the components already described in the description of the multiblade fan 4 of the first embodiment will be omitted for the sake of convenience.

[0262] like Fig.19 and Fig. 20 As shown, the multi-blade fan 104 includes a multi-blade fan body 110, a motor 121, and a holder 133. The multi-blade fan 104 is an example of an air supply unit. The multi-blade fan body 110 is an example of an air supply unit body. The motor 121 is an example of a driving unit.

[0263] The multi-blade fan body 110 includes an impeller 111, a housing 112, and a support 113. The impeller 111 is rotated around a rotation axis Ax by a motor 121, and air is sucked in from an air inlet 112a. The housing 112 accommodates the impeller 111 in a substantially donut-shaped internal space formed by a front housing 112A and a rear housing 112B.

[0264] The support portion 113 supports the housing 112. Fig.21 As shown in FIG. 1 , the support portion 113 has a cylindrical shape extending backward along the rotation axis Ax from the rear surface of the rear housing 112B. In this embodiment, the support portion 113 is integrally formed with the housing 112. The support portion 113 accommodates the motor 121 therein. Fig.21 and Fig.22A As shown, the support portion 113 has an engagement hole 113a, and the engagement claw 133a of the holder portion 133 is engaged with the engagement hole 113a, thereby connecting with the holder portion 133. Fig.21 As shown in FIG. 1 , the support portion 113 has a plurality of plate-shaped ribs 113b extending along the rotation axis Ax on the inner surface. Among the plurality of ribs 113b, a part of the ribs 113b guides the rotation inhibiting portion 138 of the holder portion 133 and locks the rotation inhibiting portion 138. In addition, when the holder portion 133 is mounted on the support portion 113, the mounting portion 137 and the first leaf spring 135A of the holder portion 133 are guided between adjacent ribs 113b. The rib 113b that locks the rotation inhibiting portion 138 is formed to be shorter than the other ribs 113b by an amount corresponding to the rotation inhibiting portion 138.

[0265] It should be noted that the support portion 113 is cylindrical and is integrally formed with the housing 112. However, for example, the support portion 113 may be formed separately from the housing 112 and integrated by being assembled or bonded to the housing 112. In addition, the support portion 113 may also have a cylindrical shape with an elliptical or polygonal cross section.

[0266] It should be noted that the structure of the multi-blade fan body 110 other than the support portion 113 is the same as the structure of the multi-blade fan body 110 of the first embodiment, and the description thereof is omitted for convenience of description.

[0267] The holder portion 133 supports the motor 121 while absorbing the vibration of the motor 121, thereby suppressing the vibration of the motor 121 from propagating to the support portion 113. The holder portion 133 is provided to cover the side surface and the rear surface of the motor 121. The holder portion 133 includes a flange portion 134, a leaf spring portion 135, a bottom portion 136, a mounting portion 137, and a rotation suppressing portion 138. The holder portion 133 is made of metal, and the flange portion 134, the leaf spring portion 135, the bottom portion 136, the mounting portion 137, and the rotation suppressing portion 138 are integrally formed.

[0268] The flange portion 134 is in contact with the support portion 113. The flange portion 134 has a ring shape extending radially outward of the motor 121.

[0269] The leaf spring portion 135 contacts the motor 121 and absorbs vibration of the motor 121. The leaf spring portion 135 includes a plurality of first leaf springs 135A and a plurality of second leaf springs 135B.

[0270] The first leaf spring 135A extends forward from the flange portion 134, and the front end portion is bent inward. In this embodiment, six first leaf springs 135A are arranged at equal intervals along the circumference of the flange portion 134. Fig.23A As shown, the first leaf spring 135A has a straight portion 135Aa, a flexure 135Ab, and a contact portion 135Ac. The straight portion 135Aa extends from the flange portion 134 along the rotation axis Ax. The flexure 135Ab extends from the straight portion 135Aa while being inclined inward relative to the rotation axis Ax. The contact portion 135Ac is provided at the front end portion that is bent inward from the flexure 135Ab and contacts the motor 121. The contact portion 135Ac extends along the axial direction of the motor 121 and contacts the side surface of the motor 121. In addition, as shown in FIG. Fig. 22B and Fig. 23B As shown, the contact portion 135Ac has a protrusion 135Ad protruding radially inward of the motor 121 and contacts the front surface of the motor 121. It should be noted that the contact portion 135Ac may not have the protrusion 135Ad.

[0271] like Fig. 23B As shown in the figure, when the motor 121 is stored in the holder 133, the flange 134 and the flexure 135Ab of the first leaf spring 135A extend along the long side direction of the motor 121 in a non-contact state with the motor 121, and the contact portion 135Ac contacts the front end of the motor 121. The flexure 135Ab is deformed so as to extend parallel to the rotation axis Ax due to the contact portion 135Ac contacting the motor 121. As a result, the first leaf spring 135A is in a state where deformation elastic force is always generated.

[0272] The second leaf spring 135B extends rearwardly from the flange portion 134 along the rotation axis Ax. The rear end portion of the second leaf spring 135B is bent inwardly so as to be recessed rearwardly and connected to the bottom portion 136. Fig.22A As shown, a portion of the second leaf spring 135B connected to the bottom 136 contacts the rear end of the motor 121 to absorb vibration of the motor 121. In this embodiment, six second leaf springs 135B are arranged along the circumferential direction of the flange 134 at equal intervals.

[0273] It should be noted that the leaf spring portion 135 includes the first leaf spring 135A and the second leaf spring 135B. However, the leaf spring portion 135 may include only one of the first leaf spring 135A and the second leaf spring 135B. The shapes and numbers of the first leaf spring 135A and the second leaf spring 135B are not limited to those of the present embodiment.

[0274] The bottom portion 136 is recessed rearward and accommodates the rear end portion of the motor 121 .

[0275] The mounting portion 137 engages with the support portion 113 to mount the holder portion 133 on the support portion 113. The mounting portion 137 extends forward from the flange portion 134 along the rotation axis Ax. The mounting portion 137 has an engagement claw 133a at the front end portion. The engagement claw 133a engages with the engagement hole 113a of the support portion 113. In the present embodiment, the two mounting portions 137 are arranged at opposite positions in the circumferential direction of the flange portion 134. In addition, the mounting portion 137 is arranged radially outward of the first leaf spring 135A.

[0276] The rotation inhibiting portion 138 inhibits the rotation of the retaining frame portion 133 relative to the support portion 113. The rotation inhibiting portion 138 extends forward from the flange portion 134 along the rotation axis Ax. The rotation inhibiting portion 138 has a cutout portion 138a at the front end portion. The cutout portion 138a is guided and locked to the rib 113b of the support portion 113. In the present embodiment, the rotation inhibiting portion 138 is arranged at four locations in the circumferential direction of the flange portion 134. In addition, the rotation inhibiting portion 138 is arranged radially outward of the first leaf spring 135A.

[0277] Thus, in the above-mentioned modification, the vibration of the motor 121 is suppressed from propagating to the support portion 113 by the holder portion 133 functioning as a vibration-proof portion. Therefore, the vibration of the motor 121 can be suppressed from propagating to the multi-blade fan body 110 of the multi-blade fan 104 via the support portion 113. In addition, the generation of vibration sound caused by the vibration of the motor 121 can be suppressed.

[0278] The holder 133 supports the motor 121 and is connected to the support portion 113. The holder 133 includes a leaf spring 135 for absorbing vibration of the motor 121. Therefore, by absorbing the vibration of the motor 121 using the leaf spring 135, the motor 121 can be supported by the holder 133 while the vibration of the motor 121 can be suppressed from being propagated to the support portion 113.

[0279] The leaf spring portion 135 includes a first leaf spring 135A in contact with the front portion of the motor 121 and a second leaf spring 135B in contact with the rear portion of the motor 121. Therefore, the vibration of the motor 121 can be further suppressed from being propagated to the support portion 113.

[0280] The holder portion 133 has a flange portion 134 in contact with the support portion 113, and the first leaf spring 135A extends from the flange portion 134 along the motor 121 in a non-contact state with the motor 121, and contacts the motor 121 at the contact portion 135Ac. The first leaf spring 135A can suppress the vibration from propagating to the flange portion 134 by absorbing the vibration of the motor 121 propagating from the contact portion 135Ac.

[0281] The holder 133 has a rotation inhibiting portion 138 which is locked to the support portion 113 and inhibits the holder 133 from rotating relative to the support portion 113. Therefore, the rotation inhibiting portion 138 can inhibit the holder 133 from rotating relative to the support portion 113 due to vibration of the motor 121.

[0282] The embodiments of the present disclosure are described above. Of course, the technical scope of the present disclosure should not be interpreted restrictively by the description of the embodiments. The present embodiment is only an example, and those skilled in the art can understand that various embodiments can be changed within the scope of the invention described in the claims. The technical scope of the present disclosure should be determined based on the scope of the invention described in the claims and its equivalent scope.

[0283] In the above-mentioned embodiment, the example in which the vehicle washer unit is provided at the rear part of the vehicle V is described. However, the vehicle washer unit may be provided at the front part of the vehicle V or at the side part of the vehicle V.

[0284] In addition, in the above embodiment, an example is described in which the cleaning object is the back-up camera 2A, 302A and the rear-view camera 2B, 302B. However, for example, the cleaning object may be any one of the back-up camera 2A, 302A and the rear-view camera 2B, 302B, or may be a camera used for other purposes. In addition, the cleaning object may also be a sensor different from a camera, such as LiDAR (Light Detection and Ranging or Laser Imaging Detection and Ranging).

[0285] In addition, in the above-mentioned embodiment, the air duct 8 supplies different amounts of air to the backup cameras 2A, 302A and the rear view cameras 2B, 302B as the cleaning objects. However, for example, the air duct 8 may supply the same amount of air to the backup cameras 2A, 302A and the rear view cameras 2B, 302B as the cleaning objects by changing the position of the partition plate 71a or the like.

[0286] In addition, in the above-mentioned embodiment, the vehicle cleaner 3, 203 has a non-volumetric multi-blade fan 4, 104 that continuously sends out as an air supply unit. However, the vehicle cleaner 3, 203 may also have an axial flow fan or a diagonal flow fan as a non-volumetric air supply device. In this case, it is necessary to change the position of the air intake 12a of the bracket 5 according to the intake of the axial flow fan or the diagonal flow fan. In addition, the vehicle cleaner 3, 203 may also have a compressed air generating unit that sends out compressed air as an air supply unit.

[0287] This application is based on Japanese Patent Application No. 2019-17121 filed on February 1, 2019, Japanese Patent Application No. 2019-17122 filed on February 1, 2019, and Japanese Patent Application No. 2019-17123 filed on February 1, 2019, the contents of which are incorporated herein by reference.
