[Problems to be Solved by Prior Art and Invention]

 In general, this type of automobile wash tank has a lid hose that fits over the outer peripheral edge of the upper end of the liquid injection hose protruding from the wash tank to cover the upper end opening of the liquid injection hose. is there. By the way, in this product, when the wash solution is injected from the injection hose, air may be trapped in the tank, which may cause the wash solution to overflow from the top opening of the injection hose. It Therefore, conventionally, as disclosed in Japanese Utility Model Laid-Open No. 57-66950 and Japanese Utility Model Laid-Open No. 57-66952, there are those in which a wash tank is provided with an air vent pipe for venting air or a liquid injection hose is integrally provided with an air vent hole. However, in these cases, the air vent tube and the air vent hole are both open during normal use with the lid closed, so there is a problem that dust and dirt may enter the tank from here. is there. On the other hand, as shown in Japanese Utility Model Application Laid-Open No. 57-66951, there is also one in which the upper end of an air vent pipe inserted in a liquid injection hose in a loose fitting manner is attached to the bottom face of the lid in a communicating state. However, in this product, when the lid is opened, the air vent pipe that hangs down from the lid is still inserted in the liquid injection hose, so when the lid is released, the lid closes the top opening. There is a problem that it is easy to return to the position and this hinders the work of injecting the wash liquid. Moreover, with this product, when the wash liquid that has flowed down the outer periphery of the air vent pipe reaches the lower end of the air vent pipe, it is sucked into the air vent pipe together with the air in the tank trying to escape to the outside. There is a problem that it moves with the air and overflows from the upper end of the air vent pipe.

[Means for Solving the Problems]

 In view of the above situation, the present invention was devised with the object of providing an air bleeding structure for a liquid injection hose in a vehicular wash tank for an automobile that can eliminate these drawbacks. The liquid injection hose includes a liquid hose and a lid that covers the upper opening of the liquid injection hose, and the washing liquid for an automobile is configured to inject the wash liquid from the upper opening of the liquid injection hose. Is divided into a liquid passage pipe part that allows the wash liquid to flow into the tank and a ventilation pipe part that allows the air inside the tank to be vented by communicating the inside and outside of the tank, and the lower end opening of the liquid passage pipe part is the ventilation pipe part. Lower than the lower end opening of the liquid passage, and the upper end opening of the liquid passage section is set higher than the upper end opening of the ventilation tube section. The upper part of the upper end opening on the ventilation pipe side is covered, and the inclination is set to reach the position corresponding to the outer peripheral edge of the ventilation pipe part. It is characterized in that it has a long tubular shape so as to reach the upper end opening position of the ventilation pipe section below the upper opening position of the liquid passage tube section. According to the present invention, when the liquid is poured into the wash tank, the work of pouring the wash liquid is easy, and the wash liquid does not overflow.

【Example】

 Next, an embodiment of the present invention will be described with reference to the drawings. In the drawings, reference numeral 1 denotes a wash tank in which the present invention has been implemented, and the wash tank 1 stores a wash liquid for cleaning window glass of an automobile. The upper surface of the wash tank 1 is As will be described later, a base end of a liquid injection hose 3 to which a lid 2 is detachably attached to an upper end opening is attached via a rubber packing member 1a.

In the liquid injection hose 3, a liquid passage pipe portion 4 for allowing the wash liquid to flow into the tank 1 and a ventilation pipe portion 5 for removing the air in the tank 1 are formed as partitions. Of the lower end openings 6 and 7 of the pipe portions 4 and 5, the lower end opening 6 of the liquid passage pipe portion 4 is lower than the lower end opening 7 of the passage pipe portion 5 so as to sink deeper into the tank 1. On the other hand, among the upper end openings 8 and 9 of both pipe parts 4 and 5, the upper end opening 8 of the liquid passage pipe part 4 is higher than the upper end opening 9 of the base pipe part 5, but the raised upper end. A portion of the opening 8 on the side of the ventilation pipe portion 5 covers the upper side of the upper end opening 9 of the base pipe portion and forms an inclined surface 8a so as to reach a position corresponding to the outer peripheral edge position of the base pipe portion 5.

On the other hand, the lid 2 has a disc-shaped ceiling portion 2a, a skirt portion 2b that hangs in a cylindrical shape from an outer peripheral edge of the ceiling portion 2a, and a knob that further protrudes from the outer periphery of the ceiling portion 2a in the outer diameter direction. The bottom portion 2c and a locking piece 2d for locking to an appropriate locking member (not shown) are formed, and the skirt portion 2b is provided with an upper end opening 8 which is elevated above the liquid passage tube portion 4. A locking groove 2e that is deeply fitted to the upper end of the liquid injection hose 3 so as to wrap around the bottom, and formed on the inner circumference of the lower end of the hem 2b. It has a cylindrical shape so as to be locked by a locking projection 2f formed corresponding to the position. Further, a breather groove 2g is formed on the inner surfaces of the ceiling portion 2a and the skirt portion 2b of the lid body 2 to let air in and out of the tank when the lid body 2 is closed.

In the embodiment of the present invention configured as described above, when the lid 2 is opened and the washing liquid is poured into the washing tank 1 from the filling hose 3, the air in the tank 1 is the vent pipe. The wash solution does not overflow as it escapes to the outside through the part 5.

That is, in the present invention, the liquid injection hose 3 is divided into the liquid passage pipe portion 4 and the ventilation pipe portion 5, and the upper end opening 8 of the liquid passage pipe portion 4 is the upper end of the ventilation pipe portion 5. It is set to be higher than the opening 9, and in addition, a sloped surface 8a is formed at a portion of the liquid pipe portion upper end opening 8 that is set to be higher so as to cover the ventilation pipe portion upper end opening. As a result, the upper end opening 9 on the side of the ventilation pipe cannot be seen directly from above, and as a result, the injection hose 3 has the ventilation pipe 5 integrally formed, but is However, it does not flow into the upper end opening 9 on the ventilation pipe section side by mistake, and the same wide-diameter injection work can be performed as if the liquid passage tube section 4 was formed over the entire diameter of the injection hose 3. Then, the wash liquid flowing down through the liquid passage pipe portion 4 is dropped into the tank 1 through the liquid passage pipe portion side lower end opening 6, but at this time, the liquid passage pipe portion side lower end opening 6 is made into the air passage pipe portion side. Since it is set to be lower than the lower end opening 7, even if the temporary ventilation pipe section 5 has a small diameter, the washing liquid will not be sucked into the ventilation pipe section 5 together with the air. Therefore, smooth and reliable injection of the wash liquid can be performed.

Further, the lid body 2 is not easily closed like the one provided with the conventional air vent pipe, and therefore, the liquid injection work is not disturbed by the lid body 2. After the liquid injection work is completed in this way, the lid body 2 is closed. However, the lid body 2 has an elongated tubular shape at the hem portion 2b and closes the vent pipe upper end opening 9 as well. When the liquid is injected, the ventilation pipe portion 5 required for removing the air in the tank 1 becomes an opening when the lid body 2 is closed, and dust and dust enter the tank 1 from here. It doesn't get lost.

[Operation effect]

 In summary, since the present invention is constructed as described above, the liquid injection hose is divided into the liquid passage pipe portion and the ventilation pipe portion, and the liquid passage pipe side upper end opening is the ventilation pipe side upper end. The ventilation pipe side upper part opening of the liquid passage side higher than the opening is inclined so as to cover above the ventilation pipe side upper end opening, and the ventilation pipe side upper end opening is formed. As a result, the injection hose has an integrally formed vent pipe, but during injection, the wash liquid erroneously flows into the top opening of the vent pipe. There is no end. Moreover, since the wash liquid flowing down the liquid passage pipe falls into the tank through the lower end opening of the liquid passage part which is set lower than the lower end opening of the air passage part, the wash liquid is discharged together with the air in the tank. It will not be sucked into the department. Therefore, smooth and reliable injection of the wash liquid can be performed. In addition, this liquid injection work has an air vent pipe that is inserted into the liquid injection hose, and the lid body can be maintained in the open state without returning to the closed state naturally when the hand is released. Therefore, the above-mentioned liquid injection work can be performed easily and surely without being obstructed by the lid and without overflow of the wash liquid from the liquid passage pipe and the ventilation pipe. be able to.

Moreover, the lid has a long tubular shape when the upper end of the liquid injection hose is closed by this, and not only the upper end opening on the liquid passage side but also the upper end opening on the ventilation pipe side is formed. The vent pipe part, which was needed to remove air from the tank when pouring, was left open when the lid was closed, and dust and dirt would enter the tank from here. In particular, it is possible to reliably avoid problems such as dust clogging the wash nozzle.
