JPS62106860A - Nozzle gun of spray type car washing machine - Google Patents

Abstract

PURPOSE:To effectively utilize jet energy and to enable the washing of all areas, by constituting a nozzle gun by connecting a handle having a jet nozzle provided to the leading end thereof and the grip part provided to the rear part of said handle in a freely bendable manner. CONSTITUTION:When the roof 22 of a car 21 is washed, a handle 30 and a grip part 6 are held by left and right hands and bent against a flexible hose 2 and a coil spring 11 to direct a nozzle 17 at a right angle to the roof 22. Therefore, even a short man can wash a high roof. When the skirt part of the car 21 is washed, the handle 30 is held to revolve a swivel joint by 180 deg. and, if necessary, the coil spring 11 is bent. Hereupon, the jet nozzle 17 can be directed at a right angle to a car body because an emitting pipe is bent in a V-shape. Therefore, even the short man can wash the skirt part of the car without stooping.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a nozzle gun for a spray-type car wash machine for washing automobiles.

[Prior Art] Recently, when a coin, for example, a 100 yen coin is inserted and a start switch is pressed, washing water, for example, water or washing water containing wax or detergent is sprayed out for a predetermined period of time, and the washing water is used to wash the car. A simple spray-type washer Φ machine using a so-called vending machine is known.

This kind of car wash machine has a pump, motor, washing water, wax,
Detergent and the like are stored in a box, and a nozzle gun is provided at the end of a hose connected to a pump in the car wash box, and the car is washed with washing water sprayed from this nozzle.

To make the operation of this nozzle gun easier,
The nozzle gun is equipped with a handle, but the problem with the conventional handle is that it is difficult to wash high parts of the car, such as the roof. Furthermore, even if the roof part can be washed, there is a problem that the spray nozzle tends to face diagonally to the roof, so the spray energy is not effectively used for washing the car. The underside of the car cannot be washed properly.

[Object of the Invention] Therefore, an object of the present invention is to provide a spray-type car wash machine having a nozzle gun with good operability, that is, a spray-type car wash machine that can easily and completely wash the roof and underside of a car.

[Configuration 1 of the Invention] In order to achieve the above-mentioned object, the present invention provides a nozzle gun with a handle and a grip part provided at a predetermined interval,
The handle and the grip are connected in a bendable manner.

[Operations and Effects of the Invention] Therefore, during operation, the operator grasps the grip portion and the steering wheel, and injects the washing water from the injection nozzle toward the automobile to be washed. The car is then washed with the washing water, but according to the present invention, the handle and the grip are connected so that they can bend freely, so the user holds the handle and the grip with each hand and bends it by a predetermined amount. be able to. Therefore, even short people can direct the spray nozzle at right angles to the roof, and the spray energy can be used effectively for cleaning. In addition, since it can be bent to any desired maximum degree, the underbody of the car can also be efficiently washed.

[Preferred Embodiment] When carrying out the present invention, the handle and the grip are connected by a flexible hose, and spirally wound coil springs are provided around the outer circumference of the hose at predetermined intervals. Preferably, the handle and the handle are connected by a spherical swivel joint so that the handle can be bent freely. In addition, it is preferable that the handle is provided at right angles to the joint attached to the flow pipe via a swivel joint, and that the grip portion is preferably formed by bending it around the outer circumference of the hose in a shape of approximately 60 degrees. .

[Example] Hereinafter, one embodiment of the present invention will be described with reference to the accompanying drawings.

Referring to FIG. 1, a nozzle gun 1 according to the present invention is attached to a hose 2 extending from a car wash box 20. As shown in FIG. As is well known, the car wash box 20 houses a pump driven by a motor, a tank for washing water detergent, wax, etc., and other valves, etc., and a hose 2 is connected to the discharge port of the pump. There is. The car wash box is equipped with a ladder control device, similar to a vending machine.

The hose 2 extends for a predetermined length, and as shown in FIG.
It is inserted into the grip part 6 bent at 0 degrees, extended for a predetermined length, and inserted and fixed into one joint 3a of the swivel joint 3.

A four part 7 is formed at the rear end of the grip part 6, and a coil spring 8 of a predetermined length is inserted and fixed into this recess, and the hose 2
is protected.

One end of a coil spring 11, which is a flexible member, is inserted and fixed into the tip end 9 of the grip part 6.

The other end of this coil spring 11 is inserted and fixed into a cover 5 fixed to the joint 3a.

The other joint 3b of the swivel joint 3 is connected to a discharge pipe 16 which is bent into a substantially square shape, and an injection nozzle 17 is provided at the tip of this discharge pipe. Note that reference numeral 18 indicates a bowl-shaped scattering prevention member for preventing washing water from scattering around.

A partially protruding thick part 19 is formed on the outer periphery of the cover 14 fixed to the joint 3b, and the base 31 of the handle 30 is screwed into this thick part, so that the cover 14 is secured to the joint 3b.
It is screwed in at a substantially right angle to 4.

When cleaning the roof 22 of the automobile 21, for example, when cleaning the roof 22 of the automobile 21, the handle 30 and the grip 6 are held in the left and right hands, respectively, and the flexible hose 2 and the coil spring 11 are removed.
When bent against the roof 22, the nozzle 17 points at right angles to the roof 22. Therefore, even a short person can clean a tall roof. Also, when cleaning the undercarriage, hold the handle 30 and turn the swivel joint 3 180 degrees and bend the flexible member as necessary.The discharge pipe 16 is bent in an F-shape, so the injection nozzle can be opened. It can be oriented at right angles to the vehicle body. Therefore, even tall people can wash the underbody of the car without bending over.

FIG. 3 shows another embodiment of the present invention, in which a handle 30 provided with an injection nozzle 17 and a grip 6 through which a hose 2 is inserted are connected by a spherical swivel joint 40. In FIG. 3, the same parts as in FIG. 2 are given the same reference numerals. This embodiment also has the same effects as the previous embodiment.

[Summary 1] As described above, according to the present invention, since the handle and the grip portion are connected in a bendable manner, the handle can be arbitrarily bent to arbitrarily select the spray direction of the spray nozzle. Therefore, the spray nozzle can be directed at right angles to both high and low places, and the spray energy can be used effectively to clean all areas.
