  The cleaning water spray nozzle group 12 includes first and second cleaning water spray nozzles 12A and 12B. The liquid spray nozzle group 13 includes first and second detergent spray nozzles 13A and 13B, and a water repellent coating. There are an agent injection nozzle 13C and a wax injection nozzle 13D. These nozzles are, for example, the first washing water jet nozzle 12A, the first detergent jet nozzle 13A, the second wash water jet nozzle 12B, the water repellent coating agent jet nozzle 13C, the second detergent jet nozzle 13B, and the wax jet nozzle 13D. Are arranged from the front part to the rear part in this order.

  Each of the injection nozzle groups 12 and 13 is attached to a plurality of support members (not shown, but may be pipes themselves) each having a front view shape formed in, for example, an arch shape (bow shape). Yes.

  The water supply pipe 14 is branched from the main supply pipe 21 (also referred to as a header) 21 connected to a water supply pipe (to be described later) on the water supply device 15 side, and an electromagnetic switching for injection in the middle. A sub-supply pipe (also referred to as a branch pipe) 22 having a valve 23 connected to each of the injection nozzles (or arches) 12 and 13 and a sub-supply pipe 22 provided with the liquid agent injection nozzle 13 are used for injection. The injector 24 is provided on the downstream side of the electromagnetic opening / closing valve 23.

  The water supply device 15 includes a water tank 31 provided on the ground side, a water pump 32 disposed in the water tank 31, and cleaning water discharged from the water pump 32. It is comprised from the water supply pipe | tube 33 supplied to the main supply pipe | tube 21 of this. In the middle of the water supply pipe 33, a flexible one, that is, a rubber hose is used so that the car wash machine main body 1 may be moved.

  Further, the liquid supply pipe 16 has one end connected to a suction port of an injector 24 provided in each sub supply pipe 22 and the other end opened into each liquid tank 17 so that the liquid supply tank 17 has an inside. The liquid agent is configured by a plurality of liquid agent supply pipes 25 that can supply (lead) the predetermined liquid supply pipe 22 to a predetermined sub supply pipe 22. A liquid agent pump for supplying the liquid agent may be provided in the middle of the liquid agent supply pipe 25 in some cases.

The car wash machine is provided with a control device for automatically performing the car wash operation.
According to the car wash course selected on the operation panel 5, the control device travels the car wash machine body 1, injects washing water and liquid from each of the injection nozzles 12 and 13, brushing operation with a brush, and drying with a drying nozzle. The operation is performed automatically, and this control device is provided with a water amount adjusting unit capable of adjusting the amount of water supply according to the type of liquid agent used, which is the gist of the present invention. The water amount adjusting unit will be described.

  As shown in FIG. 3, this water amount adjusting unit is a liquid agent (also referred to as a conventional liquid agent) that contains impurities (oil content) such as a normal hexane extract material, and contains no impurities or a small amount. Is used to increase the amount of water so that the content of impurities in the wastewater discharged from the car wash machine is less than the legally regulated value. A water increase button (an example of a water increase instruction unit) 41 that is provided to instruct an increase in the amount of water supplied and a water increase signal from the water increase button 41 are input and provided in the middle of the sub supply pipe 22. An opening time extending portion 42 for extending the set opening time of the injection electromagnetic on-off valve 23 is configured.

  That is, this car washer was designed to save water by corresponding to the improved liquid agent, and at least the set opening time at the electromagnetic on-off valve 23 for injection provided in the middle of the sub-supply pipe 22 corresponds to the improved liquid agent. The normal opening time in the case of the conventional liquid agent and the extended opening time in the case of corresponding to the conventional liquid agent (when longer than the normal opening time) is provided, and the water increase button 41 is pressed In this case, in response to the water increase instruction, the set opening time of the electromagnetic solenoid on / off valve 23 is changed to the extended opening time. More specifically, the set opening time of a timer for a predetermined work time in the car wash course (for example, an injection time in finish cleaning) is increased.

  In the above configuration, when the liquid used for the car wash is an improved liquid, the car wash may be performed at a desired car wash course without pressing the water increase button 41 provided on the operation panel 5.

On the other hand, when the liquid agent used for car washing is a conventional liquid agent, the water increase button 41 provided on the operation panel 5 is pushed before the car washing operation is started, and the washing water injection time is set longer.
Then, a desired car washing course is selected, and the start button on the operation panel 5 is pressed to start car washing.

  When the car wash is started, the car wash machine main body 1 starts to travel from the front end to the rear end of the vehicle C, and washing liquid such as washing water and liquid agent is jetted from each of the jet nozzle groups 12 and 13. The outer surface of the vehicle C is brushed by the brushes 6 to 8 and cleaned. When the vehicle C is cleaned, for example, the traveling direction of the car wash machine body 1 is reversed and the drying process is started.

  In this way, when washing a car with a car washer that saves water, the amount of water is adjusted according to the type of the liquid agent. Since the time is lengthened, the concentration of impurities in the wastewater is not more than the regulation value even in the case of a conventional liquid agent containing a large amount of impurities, and therefore, deterioration of the environment can be prevented. In other words, improvement of the environment can be maintained even when the conventional liquid agent is used.

  By the way, in the above embodiment, when the water increase button is pressed, the washing water injection time is lengthened. For example, only water from the liquid agent injection nozzle in a non-injection state (non-use state) is diluted, that is, diluted. Only water may be jetted for a predetermined time.

  That is, as shown in FIG. 4, a supply electromagnetic on-off valve 26 is provided in the middle of the liquid supply pipe 25 and the liquid injection nozzle 13 is not sprayed, that is, the liquid supply is not supplied with the liquid. The supply electromagnetic opening / closing valve 26 provided in the pipe 25 is closed, and the injection electromagnetic opening / closing valve 23 of the auxiliary supply pipe 22 related to the liquid agent injection nozzle 13 is opened for a predetermined time (set opening time) to inject only water. . In this case as well, the concentration of impurities in the wastewater can be set to a regulation value or less, as in the above-described embodiment.

  In this case, as shown in FIG. 5, the water amount adjustment unit is provided on the operation panel, for example, as shown in FIG. 5, for example, a water increase button (an example of the water increase instruction unit). ) 51 and a water increase signal from the water increase button 51 are input to close the supply electromagnetic on-off valve 26 and open the injection electromagnetic on-off valve 23 for a predetermined time (which may be simply referred to as a water supply unit). ) 52.

  Further, in the car wash machine in which only the water is supplied to the sub supply pipe 22 in order to discharge the liquid agent remaining in the sub supply pipe 22 after the injection of the liquid agent, the water for discharging the residual liquid agent is used. You may make it lengthen supply time (it can also be said to be water injection time). Of course, in this car wash machine, similarly to the one shown in FIG. 5, a supply electromagnetic on-off valve 26 is provided in the middle of the liquid supply pipe 25 and when water for discharging the remaining liquid is supplied. The supply electromagnetic opening / closing valve 26 is closed. Also in this case, since the supply amount of water increases, the concentration of impurities in the waste water can be made equal to or less than the regulation value as in the above-described embodiment.

  In this case, as shown in FIG. 6, the water amount adjustment unit includes a water increase button (an example of a water increase instruction unit) 61 provided on the operation panel to instruct an increase in the amount of water supply, The water increase signal from the water increase button 61 is input, and the opening time extending portion 62 is configured to open the injection electromagnetic opening / closing valve 23 longer than the set opening time.

  By the way, in each of the above-described embodiments, it has been described that the water increase instruction is given by pressing the water increase button. For example, by setting the necessity of the water increase in advance on the operation panel (car wash machine) Since the type of the liquid agent is known when it is set on the main body), a water increase instruction may be automatically given according to the type of the liquid agent to be used in the selected car washing course. Of course, the portion for setting whether or not the amount of water increase is necessary on the operation panel (for example, a setting button, a setting switch, etc.) is the water increase instruction portion.

  Further, although the description has been made so that the car washer is driven with respect to the vehicle, conversely, the car may be driven with respect to the car washer (that is, the car washer and the vehicle are relatively movable). As long as it is provided).
