[Embodiment]
Hereinafter, a car wash brush according to an embodiment of the present invention will be described with reference to the drawings.
First, a schematic configuration of the car wash machine will be briefly described with reference to FIG.

  In this car wash machine, a top brush 2 for cleaning the upper surface of the vehicle C is provided on the upper part of a frame body (also a car wash machine main body) 1 whose front view is a gate shape. The side brush 3 for cleaning the side surface of the vehicle C is provided, and further, a rocker brush 4 for cleaning tires and the like is provided below both side portions. Hereinafter, each of the brushes 2 to 4 will be described as a car wash brush 11.

  As shown in FIG. 2, the car wash brush 11 includes a rotating support shaft 12 and a cylindrical brush 13 attached to the rotating support shaft body 12. In the axial direction of the support shaft body 12, the support shaft body 12 is divided and attached. Hereinafter, the divided divided brush 13 'will be described.

  That is, as shown in FIG. 3, the divided brush 13 ′ includes a ring member 21 provided with a hole portion 22 that can be fitted around the support shaft body 12, and an outer periphery of the ring member 21 at predetermined intervals (a predetermined angle). And the brush material 24 respectively held in a plurality of holding grooves 23 formed in (2). In FIG. 3, only one brush member 24 is shown, but of course, a plurality of brush members 24 are arranged over the entire outer periphery.

  The support shaft body 12 is hollow and is configured so that high-temperature hot air is supplied to the hole 12a. Specifically, a high-temperature hot air generator (not shown) is provided on the frame body 1 side, and the hot air generated by the hot air generator is supplied to the support shaft 12 via a duct, piping, and the like. It is configured to be supplied into the hole 12a. The warm air is supplied to the support shaft 12 when the brush material 24 freezes in the standby car wash machine by the operator's operation.

  4 and 5, for example, the brush member 24 is formed by alternately folding a rectangular cloth (knitted with natural fibers) with a predetermined width B (in a zigzag shape). It is folded in the same plane with the middle as the center to make a fan shape (also called a fan shape).

The brush member 24 is attached to the ring member 21 as follows.
That is, the holding groove 23 includes a circular hole portion 23a and a groove portion 23b connected to the hole portion 23a and having a width narrower than the inner diameter of the hole portion 23a. At the time of attachment to 23, the folded portion of the brush material 24 is inserted into the groove portion 23b and the hole portion 23a, and in order to prevent the brush material 24 from coming off, a cylindrical shape is used as a core material in the hole portion 23a. The locking member 25 is inserted.

  Furthermore, the heat conductive wire 31 is arranged along an appropriate position of the cloth brush material 24, for example, along the folded peak portion 24a or valley portion 24b. If it demonstrates concretely, as shown in FIG. 5, the heat conductive wire 31 will be arrange | positioned at linear intervals on the sheet-like member S made from a rectangular cloth. For example, when the part of this heat conductive wire 31 is just folded, it is located along the peak part 24a and / or valley part 24b, and located in the peak part 24a and / or valley part 24b, respectively. .

  Further, the arrangement surface of the heat conductive wire 31 is preferably located on the inner surface side so as not to come into contact with other brush members and the vehicle body of the washing vehicle when folded, as shown by the broken line in FIG. In addition, it is arranged on the back side in the peak portion 24a, and is arranged on the front side as shown by the solid line in the valley portion 24b (of course, it may be arranged collectively on either surface). In addition, by arranging the heat conductive wire 31 in the peak portion 24a and the valley portion 24b, at least the portion that contacts the cleaning vehicle is surely thawed.

The heat conductive wire 31 is made of carbon fiber such as carbon nanotube.
And as a method of attaching the said heat conductive wire 31 to the cloth-made brush material 24, after arrange | positioning the said heat conductive wire 31 to one surface (for example, back surface) of one cloth, this heat conductive wire At least one cloth larger than 31 (may be the same cloth as the brush material or a cloth made of a different material) and sewn so as to cover and sandwich the heat conductive wire 31 Or you may affix with an adhesive agent. Of course, a sandwich type in which the heat conductive wire 31 is disposed between two sheets of cloth may be used. In this case, it is not necessary to distinguish between the front and back of the arrangement surface of the heat conductive wire 31.

In particular, when the heat conductive wire 31 is disposed, at least some portion (end portion or intermediate portion) is provided so as to approach the support shaft body 12.
For example, it is desirable to arrange the heat conductive wire 31 over substantially the entire length of the sheet-like member S and make it into a fan shape by further folding the center in a zigzag manner. By doing in this way, a part of heat conductive wire 31 will be arranged inside ring member 21 (holding groove) directly attached to support shaft body 12, and heat transmitted to support shaft body 12 will be carried out. This is because it can be best transmitted to the heat conductive wire 31 via the ring member 21. More specifically, the holding groove 23 a that holds the brush material 24 is formed so as to approach the inner surface of the hole 22 of the ring member 21. In some cases, a part of the holding groove 23 a may be communicated with the hole 22, and a part of the brush material 24 may be brought into direct contact with the support shaft body 12.

Of course, as the material of at least the support shaft body 12 and the ring member 21, a metal such as a steel plate having good thermal conductivity is used.
When the car wash is performed by the car wash machine having the car wash brush according to the above-described configuration and the car wash operation is completed, the car wash machine body returns to a predetermined retreat position and stops and enters a standby state.

If the outside air temperature is less than or equal to zero degrees during this standby time, the water remaining on the brush material 24 is naturally frozen.
In this state, when the car wash operation is started, first, the hot air generator provided in the frame body 1 is driven to supply hot hot air to the hole 12a of the support shaft body 12. . Then, the support shaft 12 is heated, and the heat is transmitted to the heat conductive wire 31 disposed on the brush member 24 via the ring member 21, so that the entire brush member 24 is warmed. That is, the frozen brush material 24 is melted in a short time, and the car washing operation can be started more quickly than in the conventional case where the hot air is blown from the outside of the brush material.

  By the way, in the said embodiment, although the heat conductive wire was arrange | positioned so that it might come to the mountain part or valley part folded into a fan shape, it is the intermediate plane part 24c (FIG. 5) between a mountain part and a valley part. Arranged on the plane of the sheet-like member, in parallel with the crease, at a predetermined interval, the heat conductive wire is arranged in a straight line, and the sheet-like member has a predetermined width. Therefore, it may be folded (in this case, the heat conductive wire is not necessarily located in the peak or valley).

  Moreover, in the said embodiment, although the normal cloth (what is called what knitted natural fiber) was used as a material of a brush material, what knitted synthetic fibers, such as nylon, for example may be used.

  In the above embodiment, the heat conductive wire is arranged on the surface of the sheet-like member. For example, the fibers constituting the heat conductive wire are knitted into the sheet-like member. Also good. In this case, the heat conductive fibers themselves may be knitted as a whole, or may be knitted with a predetermined width and at predetermined intervals.

  Moreover, in the said embodiment, although demonstrated as what folded a sheet-like member as a brush material, it is not limited to such a shape, For example, what is not folded, for example, the shaft center of a support shaft body The present invention can also be applied to a planar member arranged in an orthogonal plane, that is, an annular sheet member.

  Furthermore, in the above embodiment, the heating shaft is heated to supply the hot air to the hole portion. However, for example, a heater (heating wire) may be embedded in the supporting shaft body.
