Description

  The present invention relates to a car wash machine provided with a pair of top brushes in a car wash machine body so that an automobile can be washed with the top brush.

Conventionally, in a normal car wash machine, only one top brush is provided in the car wash machine body, but a car wash machine in which two top brushes are provided in the car wash machine body is already known (for example, the following patent document) 1 and 2).
JP-A-62-273150 JP-A-11-222108

  However, in a conventional car wash machine having two top brushes, two top brushes having the same structure are used, and the brush hairs of both brushes are made of the same material. Effective cleaning that matched the different characteristics of the two areas of the car body was not possible.

  For example, the bristle made of synthetic resin bristle is relatively soft and has an advantage that it can be cleaned without damaging the protrusions of the vehicle body, but has a disadvantage that the cleaning effect of the vehicle surface is not high. Brush bristles made of foam have the advantage of being well-familiar with the surface of the vehicle when it contains water and have a high cleaning effect on the surface of the vehicle, but have the disadvantage of being easily entangled and damaged by protrusions on the surface of the vehicle. Since only one of synthetic resin bristle or cloth or foam cleaning body is used as the brush material of the top brush in the car wash machine, it corresponds to the protrusion in an automobile having a protrusion on the body surface. It was not possible to effectively distinguish between the area and the area connected before and after the area.

  The present invention has been proposed in view of the above, and it is a first object of the present invention to provide a car wash machine that can be effectively washed according to the characteristics of two different areas of the car body surface to be washed. It is a second object of the present invention to provide a car wash machine capable of effectively cleaning an area corresponding to an object and an area continuous before and after the area.

  In order to achieve the first object, a first aspect of the present invention provides a car wash machine in which a pair of top brushes are provided in a car wash machine body, and the car can be washed with the top brushes. The material of the bristle is different in at least a part of the areas of the top brushes.

  In order to achieve the second object, a second aspect of the present invention provides a car wash machine in which a pair of top brushes are provided in a car wash machine body, and the car having protrusions on the upper surface of the vehicle body can be washed with the top brush. In one top brush, a portion of the bristle corresponding to the protrusion is composed of a synthetic resin bristle, and the other top brush has a portion of the bristle corresponding to the protrusion being a cloth or foam. It is characterized by comprising a washed product.

  As described above, according to the first aspect of the present invention, it is possible to perform effective cleaning that matches the characteristics of the region of the vehicle body surface to be cleaned.

  According to the second aspect of the present invention, the region corresponding to the protrusion on the vehicle body surface is one top brush in which the bristle of the portion corresponding to the protrusion is made of a synthetic resin bristle. The region connected to the front and back of the region corresponding to the protrusion can be cleaned with the other top brush in which the brush bristles corresponding to the protrusion are made of a cloth or a foam cleaning body. As described above, the region corresponding to the protrusion on the vehicle body surface and the region connected before and after the region can be accurately and effectively washed.

  Embodiments of the present invention will be specifically described below based on the embodiments of the present invention illustrated in the accompanying drawings.

  DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. 1 is a gate-type frame as a car-washing machine body which is formed in a gate shape so that an automobile V as a vehicle to be cleaned can pass through in the front-rear direction. The portal frame 1 is mounted on the rails 2 and 2 laid on the ground via the guide wheels 3 and 3, and is reciprocated on the rails 2 and 2 by driving a driving motor (not shown). It is like that.

  The portal frame 1 is provided with a front top brush Tf and a rear top brush Tr that are arranged close to each other in the front-rear direction at a middle portion in the front-rear direction, and a pair of left and right is disposed on the rear side of the rear top brush Tr. Side brushes Sl and Sr are disposed, and a front nozzle TN, a side nozzle SN, and a pair of left and right rocker brushes Rl and Rr are disposed on the front side of the front top brush Tf. Furthermore, an operation panel having a built-in control device C comprising a microcomputer for controlling the operation of the brushes Tf, Tr, Sr, Sl, Rl, Rr and the nozzles TN, SN at the front end of the portal frame 1. CP and a vehicle body upper surface position detecting device K having a large number of photoelectric elements arranged at equal intervals in the vertical direction are arranged. A plurality of cleaning water spray nozzles (not shown) are disposed on the upper part of the portal frame 1. Note that the front side of the portal frame 1 refers to the side closer to the vehicle V (right side in FIG. 1) when viewed from the frame 1 at the start position (left end in FIG. 1), and the rear side refers to the side far from the vehicle V. (Left side in FIG. 1).

  Thus, like the conventional car washer, the top surface of the vehicle body and the front and rear end portions can be brushed and cleaned by the top brushes Tf and Tr, and the side surface and front and rear end surfaces of the vehicle body can be brushed and cleaned by the side brushes Sr and Sl. In addition, the lower side of the vehicle body can be brushed and cleaned by the rocker brushes Rl and Rr, and the upper surface and the side surface of the vehicle body can be dried by the top nozzle TN and the side nozzle SN, respectively. The position of the upper surface of the vehicle body can be detected by the element. The control device C detects the vehicle shape of the automobile V to be cleaned based on the detection signal from the vehicle body upper surface position detection device K and the detection signal from a travel position detection device (not shown) that detects the travel position of the portal frame 1. And the top brush Tr and the like can be controlled based on the detection result.

  Further, the front top brush Tf and the rear top brush Tr are spaced apart from each other in the front-rear direction (left-right direction in FIG. 1) of the outer periphery of the top brushes Tf, Tr in the front-rear direction (left-right direction in FIG. 1). In particular, in the illustrated example, the distance between the rotation shafts 20 of the top brushes Tf and Tr is the maximum diameter of the side brushes Sr and Sl (that is, the outer diameter during rotation). ) To be smaller than each other. In addition, the top brushes Tf and Tr rotate in the same direction during cleaning, and at least a part (both ends in the illustrated example) of the top brushes Tf and Tr in the axial direction is in mutual contact with each other. Since the brush bristles 30 of both top brushes Tf and Tr move in opposite directions and rub against each other at the contact portion, the cleaning effect of the top brushes Tf and Tr themselves can be enhanced. Thus, the brushes Tf and Tr are kept clean for a long period of time, and the cleaning effect on the upper surface of the vehicle body is improved.

  In addition, the pair of top brushes Tf and Tr are different in the material of the brush bristles 30 in at least a part of the axial direction of the top brushes Tf and Tr. That is, in the illustrated example, one top brush, for example, the front top brush Tf, has a left-half brush bristles 30B corresponding to protrusions (for example, a rear mirror RM, a rear wiper RW, etc. described later) on the upper surface of the vehicle V. The brush hair 30A in the right half is formed of a cloth or foam cleaning body. In the other top brush, for example, the rear top brush Tr, all brush hairs 30 including portions corresponding to the protrusions are made of a cloth or a foamed cleaning body.

  Next, a structure for attaching the rear top brush Tr to the portal frame 1 will be described.

  A pair of left and right guide rails 4, 4 are vertically fixed to the left and right sides of the portal frame 1, and movable carriages 6, 6 that support the brush support shaft 5 are mounted on both sides of the guide rails 4, 4. The movable carriages 6 and 6 are moved up and down along the guide rails 4 and 4 by a lifting device 8 described below.

  One end of each of upper and lower chains 11 a and 11 b is attached to the upper and lower edges of each movable carriage 6, 6, and the upper chain 11 a is rotatably supported on the upper part of the portal frame 1. The other end of the lower chain 11b is connected to the upper end of the weight 14 via a chain wheel 13 fixed to the upper end of the weight 14, and the other end of the lower chain 11b is connected to the weight 14 via a chain wheel 15 pivotally supported on the portal frame 1. The weight of the movable carriage 6 and the sum of the total weights of the front top brushes Tf supported thereby are substantially balanced with the weights of the left and right weights 14.

  A driven sprocket 16 is fixed to one end of the rotary support shaft 12, and this driven sprocket 16 is linked to a drive sprocket 19 fixed to an output shaft of a brush moving motor 18 via a transmission chain 17. By rotating forward, the rotation support shaft 12 is rotated in one direction, the movable carriages 6 and 6 are lowered via the upper and lower chains 11a and 11b, and when the motor 18 is driven in reverse, the movable carriages 6 and 6 are raised. It has become so.

  The brush support shaft 5 fixedly supported between the movable carriages 6 and 6 is fitted with both ends of the rotary shaft 22 having a hollow cylindrical shape of the rear top brush Tr through a bearing so as to be rotatable. The base of the brush bristles 30 made of the cloth of the rear top brush Tr or the foamed cleaning body is fixed to the outer periphery of the shaft 22.

  A driven sprocket 24 is fixed to one end of the rotary shaft 22, and this driven sprocket 24 is attached to a drive sprocket 28 fixed to an output shaft 27 of a brush drive motor 26 fixedly supported on the brush support shaft 5 via a bracket 25. Accordingly, the brush drive motor 26 is driven to rotate the rotary shaft 22 through the output shaft 27, the drive sprocket 28, the transmission chain 29, and the driven sprocket 24. The top brush Tf can be rotated. The driven sprockets 24 and 28 and the transmission chain 29 are built in the bracket 25.

  The brush moving motor 18 is controlled by the control device C based on a detection signal of a load detection device (not shown) that detects a contact load of the rear top brush Tr with respect to the vehicle body surface. A torque detector that detects the rotational torque of the brush drive motor 26 is used as the load detection device.

  That is, the control device C is configured to detect the power consumption of the brush drive motor 26 and to control the brush moving motor 18 forward and backward. For example, when the rotational torque of the brush drive motor 26 is equal to or less than a predetermined lower limit value. The brush moving motor 18 is driven to rotate forward to lower the top brush Tr. If the rotational torque of the brush drive motor 26 does not recover to a predetermined range at this time, the top brush Tr continues to descend to the lower limit position and the lower limit switch ( (Not shown) is turned on to stop the brush moving motor 18 and when the rotational torque of the brush drive motor 26 is within the set range, the operation of the brush moving motor 18 is stopped, and the rotational torque of the brush drive motor 26 is further stopped. Exceeds a predetermined value, the brush moving motor 18 is driven in reverse to raise the top brush Tr. At this time, when the rotational torque of the brush drive motor 26 exceeds a predetermined upper limit value, the operation of the car wash machine is completely stopped.

  Thus, since the operation of the brush moving motor 18 is controlled according to the contact load on the vehicle body surface of the rear top brush Tr, that is, the rotational torque of the brush drive motor 26, the elevation of the rear top brush Tr is controlled. The rear-side top brush Tr can be moved up and down following the upper surface of the vehicle body with an appropriate contact surface pressure when going forward and backward with the portal frame 1. Such a method of raising and lowering control is conventionally known, and is described in, for example, Japanese Patent Application Laid-Open No. 59-106350.

  The load detection device may be any device that can detect at least the contact load of the top brush Tr. In addition to the illustrated example, the load detection device is a detection device that detects the current, power, or rotation speed of the brush drive motor 26. Alternatively, a detection device that detects a reaction force moment accompanying the rotation of the top brush may be used as the load detection device.

  Next, a structure for attaching the front side top brush Tf to the portal frame 1 is basically the same as the structure for attaching the rear side top brush Tr to the portal frame 1 and will not be described. To do. However, the brush moving motor 18 that drives the front top brush Tf to move up and down is based on a detection signal from the vehicle body upper surface position detection device K and a detection signal from a travel position detection device (not shown) that detects the travel position of the portal frame 1. The front top brush Tf is controlled to be raised and lowered by being controlled according to the vehicle shape of the detectable vehicle V. That is, the elevation position of the front top brush Tf is controlled to a target level that is a certain level higher than the detected upper surface shape of the vehicle V, so that the contact surface pressure with the upper surface of the vehicle is always a substantially appropriate value. Such a method of raising and lowering control according to the vehicle shape of the top brush is well known in the art, and is described in, for example, Japanese Patent Publication No. 4-43017.

  By the way, as shown in FIG. 7, the rear top brush Tr of the pair of top brushes Tf, Tr has a large inclination of the left and right intermediate portions m, m respectively directed from the central portion of the vehicle body front end portion to the left and right corner portions. The first type of automobile V1 is suitable for cleaning, and the front top brush Tf is suitable for cleaning the second type of automobile V2 having a small inclination.

  That is, the penetration depth E2 of the rear top brush Tr suitable for cleaning the first type of vehicle V1 with respect to the front end of the vehicle body of the first type of vehicle V1 is equal to that of the second type of vehicle V2. The front top brush Tf suitable for cleaning is set to be larger than the penetration depth E1 at the time of cleaning with respect to the front end portion of the vehicle body of the first type automobile V1. In addition, the rear top brush Tr suitable for cleaning the first type of automobile V1 has the brush bristles 30 at positions corresponding to the left and right intermediate portions of the front end of the vehicle body orthogonal to the axis of the outer periphery of the rotary shaft 22. The front top brush Tf, which is attached to the plane with an inclination angle and is suitable for cleaning the second type of vehicle V2, has brush bristles 30 in the position corresponding to the left and right middle portions of the front end of the vehicle body. On the other hand, it is attached to the outer periphery of the rotating shaft 22 with an inclination angle smaller than the brush bristles 30 of the rear top brush Tr, or is attached to the outer periphery of the rotating shaft 22 substantially along the plane as shown in the illustrated example. For the above attachment, the outer periphery of the left and right intermediate portions of the rotating shaft 22 of the rear top brush Tr is formed on the outwardly expanding tapered surface 22t, and the large diameter end of the tapered surface 22t is the large diameter of the rotating shaft 22. The cylindrical outer end portion 22e and the small-diameter end thereof are continuous with the small-diameter cylindrical central portion 22c of the rotary shaft 22, respectively, and the brush bristles 30 of the rear top brush Tr according to the outer peripheral shape of the rotary shaft 22. Is formed in a drum shape.

  Further, the front top brush Tf has a rotary shaft 22 formed in a simple cylindrical shape, and the bristles 30 are arranged on the outer periphery of the rotary shaft 22 so as to be substantially along a plane perpendicular to the axis line over the entire axial direction. . In addition, the brush bristles 30 attached to both outer ends of the outer peripheral portion of the rotating shaft 22 are formed longer than the inner brush bristles. Therefore, the front side top brush Tf is centered at both ends at the time of rotation. The diameter is larger than that of the portion, so that it can easily go around the corner portion of the front end of the vehicle body, and the corner portion can be cleaned accurately.

Thus, as described above, one of the pair of top brushes Tf and Tr (rear side top brush Tr) is inclined by the left and right intermediate portions m and m respectively directed from the center portion of the vehicle body front end portion to the left and right corner portions. Since the first type automobile V1 having a large slope is suitable for cleaning the other type (front top brush Tf), the second type automobile V2 having a small inclination is suitable for washing. Even in the case of the automobile V1 having a large inclination of the left and right intermediate portions m, m respectively directed from the center of the vehicle body front end portion to the left and right corner portions, and the vehicle V2 having a small inclination, it is possible to cleanly clean the vehicle body front end portions without leaving them unwashed. Next, the operation of the embodiment will be described.
[Washing passenger cars]
When washing a passenger car type vehicle V, as shown by the solid line in FIG. 1, the gate-type frame 1 is kept at the start position and the vehicle V is stopped at a predetermined car wash position, and the operation panel CP of the car wash machine is used. The car wash is started by selecting a car wash course and vehicle type and pressing the start button. As a result, the top brushes Tf and Tr are rotationally driven, and when they are lowered from the upper limit position (chain line position in FIG. 1) to the lower limit position (solid line position in FIG. 1), a driving motor (not shown) is driven. The mold frame 1 starts to travel (FIG. 8 (A)).

  When the front top brush Tf reaches the front end of the vehicle V by the advancement of the portal frame 1 (FIG. 8B), the front top brush Tf thereafter detects the vehicle top surface detection device K and the detection signal of the travel position detection device. In accordance with the detected vehicle shape detected in advance, the upper surface of the vehicle body is controlled so as to follow the upper surface of the vehicle body and the upper surface of the vehicle body is cleaned. On the other hand, the rear top brush Tr is in contact with the vehicle body surface (that is, brush rotation). In accordance with the rotational torque of the motor 26, the upper surface of the vehicle body is cleaned so as to follow the upper surface of the vehicle body to clean the upper surface of the vehicle body ((B) to (E) in FIG. 8). However, the rear top brush Tr is controlled so as to avoid the rear glass at the portion corresponding to the rear glass, so that even if the avoidance instruction described later is neglected, the brush hair is made of cloth or foaming synthetic resin. Thus, the risk of damaging the rear wiper that may be provided on the rear glass can be avoided.

  When the portal frame 1 reaches the reversal position (the chain line position in FIG. 1) and the forward movement is finished, the brush rotation direction is reversed and the backward movement of the portal frame 1 is started. Also in this case, basically, the front top brush Tf is controlled to move up and down in accordance with the detected vehicle shape, and the rear top brush Tr is controlled to move up and down in accordance with the contact load, as in the case of going forward ((W) to FIG. 8). The rear top brush Tr is controlled so as to avoid the rear glass in the rear glass corresponding portion, as in the case of going forward, so that even if the avoidance instruction described later is neglected, The risk of damaging the rear wiper that may be provided on the rear glass by the rear top brush Tr whose brush bristles are made of cloth or foamable synthetic resin can be avoided. When the portal frame 1 returns to the start position, the cleaning process ends.

  In the cleaning step, cleaning water is sprayed from a cleaning water spray nozzle (not shown), and the side brushes Sr and Sl operate in the same manner as a conventionally known car wash machine. Moreover, after completion | finish of the said washing | cleaning process, the portal frame | frame 1 is reciprocated and a rinse process and a drying process are performed, but since it is not the summary of invention, description is abbreviate | omitted.

In addition, if a rear wiper avoidance key serving as an avoidance instruction input means is pressed before washing, and an avoidance instruction is given, the front top brush Tf whose brush bristles corresponding to the rear wiper are made of synthetic resin bristle is also compatible with the rear glass. In the portion, control is performed so as to avoid the rear glass in the same manner as the rear side top brush Tr, and therefore, damage to the rear wiper is more reliably prevented.

[Standard cleaning of one-box type cars]
When washing a one-box type vehicle V, the car wash course and vehicle type are selected on the operation panel CP of the car wash machine with the gate-type frame 1 waiting at the start position and the vehicle V stationary at a predetermined car wash position. When the start button is pressed, the car wash is started. From the start until the top brushes Tf and Tr reach the rear end of the ceiling surface of the vehicle V ((A) to (E) in FIG. 9), basically the same lift control is performed as in the case of washing of a passenger car type. Made. Thereafter, the front top brush Tf is cleaned at the rear end of the upper surface of the vehicle body as in the case of the passenger car type cleaning, but the ceiling cleaning height is maintained for the rear top brush Tr. Thus, the rear end of the upper surface of the vehicle body is not cleaned ((f) to (h) in FIG. 9). Therefore, even if the avoidance instruction to be described later is neglected, the rear top brush Tr in which the brush bristles 30 are made of cloth or foaming synthetic resin may be provided at the rear end of the vehicle body. The risk of damaging the rear wiper RW can be avoided. In the case of an automobile with a rear mirror RM, as shown in FIGS. 10E to 10G, the front top brush Tf is controlled to be lifted up and down so as to bypass the rear mirror RM based on the detected vehicle shape.

When the outward movement of the portal frame 1 is completed, the brush rotation direction is reversed, and the backward movement of the portal frame 1 is started. In this case as well, basically, the front top brush Tf is controlled to move up and down according to the detected vehicle shape, and the rear top brush Tr is controlled according to the contact load, respectively. In the same way as when going forward, until the rear end of the vehicle body ceiling surface is reached, control is performed so as to avoid the rear end portion of the upper surface of the vehicle body. The risk of damaging the rear mirror RM and the rear wiper RW, which may be provided at the rear end of the vehicle body, can be avoided when the rear top brush Tr 30 is made of cloth or foamable synthetic resin. When the portal frame 1 returns to the start position, the cleaning process ends.

[Washing when there is a rear-mirror avoidance instruction in a one-box type car]
In addition, when a rear mirror avoidance key (not shown) as an avoidance instruction input means provided on the operation panel CP is pressed during car washing, the rear top brush Tr is controlled without an avoidance instruction by the avoidance key. And only the control of the front top brush Tf is different from the case where there is no avoidance instruction. That is, when the front top brush Tf reaches the rear end of the vehicle body ceiling surface, the front top brush Tf is slightly lowered along the rear mirror RM, and then advances while maintaining the ceiling surface cleaning height, and passes through the rear mirror RM with a margin. It descends to the lower limit position ((e) to (h) in FIG. 11). Then, when the portal frame 1 goes backward, it comes into contact with the rear end of the upper surface of the vehicle body at the lower limit position, and after rising by a predetermined amount, the portal frame 1 is slightly re-traveled to move the front top brush Tf. When it is separated from the rear end of the upper surface of the vehicle body and the direction of rotation of the brush is changed and then raised again to reach the ceiling cleaning height, the raising is stopped and the portal frame 1 is re-returned. When the front top brush Tf reaches the rear end of the vehicle body ceiling surface, the brush rotation direction is changed ((R) to (F) in FIG. 11). The subsequent steps are the same as when there is no avoidance instruction. According to such avoidance control, the front top brush Tf in which the brush bristles 30B corresponding to the rear mirror are made of synthetic resin bristle can effectively clean the rear end of the upper surface of the vehicle body while avoiding the rear mirror RM. Damage can be prevented more effectively.

[Washing when there is an instruction to avoid rear wiper in a one-box type car]
Further, when a rear wiper avoidance key (not shown) as an avoidance instruction input means provided on the operation panel CP is pressed at the time of car washing, the rear top brush Tr is controlled without an avoidance instruction by the avoidance key. And only the control of the front top brush Tf is different from the case where there is no avoidance instruction. In other words, when the front top brush Tf reaches the rear end of the vehicle body ceiling surface, the front top brush Tf moves forward while maintaining the height of cleaning the ceiling surface up to that point, and descends to the lower limit position when passing through the rear wiper RW with a margin (see FIG. 12 (i) to (chi)). When the portal frame 1 goes backward, it comes into contact with the rear end of the upper surface of the vehicle body at the lower limit position. After that, the portal frame 1 is lifted by a predetermined amount that is smaller than that in the case of the rear mirror avoidance instruction, and then the portal frame 1 is slightly restored. The front top brush Tf is moved away from the rear end of the upper surface of the vehicle body and the direction of rotation of the brush is changed. Thereafter, the lift is stopped again when the height is reached again by reaching the ceiling cleaning height. Let go. When the front top brush Tf reaches the rear end of the vehicle body ceiling surface, the brush rotation direction is changed ((R) to (F) in FIG. 12). The subsequent steps are the same as when there is no avoidance instruction. According to such avoidance control, the front top brush Tf in which the brush bristles 30B corresponding to the rear wiper are made of synthetic resin bristle can effectively clean the rear end of the upper surface of the vehicle body while avoiding the rear wiper RW. Damage can be prevented more effectively.

Thus, according to the above embodiment, the front top brush Tf and the rear top brush Tr are arranged so that the outer periphery of both the top brushes Tf and Tr at the time of rotation is the longitudinal direction of the portal frame 1 (the horizontal direction in FIG. 1). ) Are arranged close to each other such that the mutual distance between them is smaller than the maximum diameter of the side brushes Sr, Sl, and in particular in the illustrated example, the distance between the rotation axes 20 of the top brushes Tf, Tr is the side brush Sr, The vehicles V are sufficiently close to each other so as to be smaller than the maximum diameter of Sl (that is, the outer diameter at the time of rotation). The pair of front and rear top brushes Tf and Tr can be used for cleaning. In this case, at the time of traveling, immediately after the fine dirt is lifted from the surface of the vehicle body by washing with the preceding front side top brush Tf, it can be re-washed again with the rear side top brush Tr that tracks the body surface. When returning to the frame 1, as in the case of going forward, immediately after the fine dirt is lifted from the vehicle body surface by washing with the preceding rear top brush Tr, the front top brush Tf that tracks the vehicle body surface is re-started again. Since it can be cleaned, the entire body surface can be cleaned cleanly. Moreover, since the body surface can be washed twice with the pair of front and rear top brushes Tf and Tr during the backward movement of the gate-type frame 1 from the opposite direction to the forward movement, the forward and reverse movements with different brush operating directions can be performed. The car body surface can be washed with high density without unevenness by performing the brushing washing twice each time. As a result of the above, it is possible to clean cleanly even in a short time even for a very dirty automobile V.

  Further, in this embodiment, the front end portion of the bonnet upper surface of the passenger car type automobile V is cleaned twice both when the top brushes Tf and Tr are going forward and backward, so the front end portion of the bonnet surface where dirt is easily noticeable. The finish against is good.

  In the above-described embodiment, the pair of top brushes Tf and Tr are brush brushes in at least a part of the top brushes Tf and Tr (regions corresponding to protrusions such as the rear mirror RM and the rear wiper RW in the illustrated example). In other words, one of them (the front top brush Tf) has a bristle 30B corresponding to the projection formed of a synthetic resin bristle, and the other (the rear top brush Tr). ), All the bristles 30 including a portion corresponding to the protrusion are made of a cloth or a foamed cleaning body. Therefore, the region corresponding to the protrusion on the vehicle body surface is cleaned while increasing the safety against the protrusion with the front top brush Tf in which the bristle 30B corresponding to the protrusion is made of a synthetic resin bristle. In addition, in the region continuous before and after the region corresponding to the projection, the brush bristles 30 corresponding to the projection can be cleaned cleanly with the rear top brush Tr made of a cloth or foam cleaning body. it can. As a result, as is clear from the above-described embodiment, the safety corresponding to the protrusions is sufficiently secured, and the region corresponding to the protrusions on the vehicle body surface and the region connected to the front and rear of the region are paired with a pair of top brushes. It is possible to accurately and effectively wash using Tf and Tr.

  Although the embodiments of the present invention have been described in detail above, the present invention is not limited to the above-described embodiments, and various small design changes can be made without departing from the present invention described in the claims. Is possible.

  For example, in the above-described embodiment, the present invention is such that the vehicle V is stationary, the frame 1 as the car wash machine body is reciprocated back and forth with respect to the vehicle V, and the frame 1 is provided with a processing device and a drying device. Although what was implemented in the mobile car wash machine was shown, in this invention, it was equipped with the fixed flame | frame and the vehicle moving means to move a motor vehicle to the front-back direction with respect to the fixed flame | frame, A pair of top brushes to this flame | frame You may implement in the car wash machine which provided cleaning means, such as.

  Moreover, in the said Example, although the car wash machine provided with the rear wiper avoidance key and rear mirror avoidance key as an avoidance instruction | indication input means is shown, in this invention, it can implement also in the car wash machine which is not equipped with such an avoidance instruction input means. It is.

  Moreover, in the said Example, the brush hair 30B of the left half area | region of one top brush Tf is made from a synthetic resin bristle, the brush hair 30A of the right half area | region is made from cloth or a foam washing body, and the other side Although all of the bristles 30 of the top brush Tr are made of a cloth or foam cleaning body, the invention of claim 1 shows at least a partial region of one top brush Tf and the other top brush Tr.
