  The present invention relates to a car wash machine installed in a gas station, for example, and used for car washing, and more particularly to a car wash machine equipped with a high-pressure pump for injecting wash water at a high pressure.

  Conventionally, as a car wash machine used for car washing, it is installed in a gas station, etc., and the liquid agent and washing stored in the liquid storage tank in the car to be washed are moved relative to each other in the front-rear direction. 2. Description of the Related Art A car wash machine that performs water washing by jetting water and brushing is known. In addition, there is a gate-type car wash machine that has a gate shape so that the main body of the car wash machine straddles the vehicle to be cleaned. As this car washing process, it has a washing process which brushes and wash | cleans, spraying a liquid agent and washing water, and has a drying process which blows and dries after washing.

  In the washing step, first, dirt is removed using washing water, then washing is performed using a liquid agent such as shampoo, and further washing is performed using washing water. After this washing process, a drying process is performed in which air is blown from each blowing nozzle and dried. In addition, car washing is performed by appropriately combining liquid agent (coating agent) application processes such as a water repellent coat and wax as necessary. In addition, an operation panel and a remote panel are provided for selecting a desired mode from a plurality of car wash modes, selecting a type of liquid agent to be used, and setting a predetermined car wash mode.

  By performing high-pressure cleaning (tilt high pressure) with a high-pressure pump, dirt and foreign matter adhering to the vehicle body can be removed cleanly and a high cleaning effect can be obtained. However, since the amount of water to be used increases when high-pressure washing is performed, it is difficult to obtain a water-saving effect.

  In addition to the low-pressure pump that is installed to perform a normal car wash, such as a car wash machine with a high-pressure spray, a configuration in which a high-pressure pump for high-pressure spray is installed increases the equipment cost of the car wash machine. It becomes a problem.

  Therefore, it is desired to realize a car washing machine that can reduce the equipment cost of the entire car washing machine and can achieve a high washing effect that can be achieved by using a high-pressure pump and a sufficient water saving effect.

  In view of the above problems, the present invention can achieve a high washing effect and a sufficient water-saving effect in a car washing machine that performs car washing while relatively moving the car washer main body and the vehicle to be washed in the front-rear direction, and further reduces the equipment cost. An object of the present invention is to provide a car wash machine capable of reducing the above.

  In order to achieve the above object, the present invention provides a car washing machine that performs car washing while relatively moving the car wash machine body and the vehicle to be washed in the front-rear direction, and has a washing process and a drying process as the car washing process, Has a high-pressure washing step and a low-pressure washing step, has a plurality of injection nozzles as washing means, and has a high-pressure pump and a water amount adjusting means comprising a multistage solenoid valve for supplying washing water to the injection nozzles A water distribution section is provided, and the high-pressure pump is used for the low-pressure washing step, and the amount of water is smaller than that used in the high-pressure washing step via the water amount adjusting means.

  According to this configuration, water is supplied to the high-pressure washing process and the low-pressure washing process for performing washing through the same high-pressure pump and the water distribution unit having the water amount adjusting means. Equipment costs can be reduced compared to car wash machines. In addition, since a high-pressure pump is provided, high-pressure cleaning that exhibits a high cleaning effect can be performed. Moreover, since the water amount adjusting means is provided, it is possible to clean with the same amount of water as that of the conventional low-pressure pump by adjusting to the predetermined amount of water necessary for cleaning, even if a high-pressure pump is used. A water-saving effect can be achieved. That is, it is possible to obtain a car wash machine that can achieve a high cleaning effect and a sufficient water saving effect and can further reduce the equipment cost.

  Further, in the car wash machine having the above-described configuration, the water amount adjusting means may be configured such that the water flow rate by the multistage solenoid valve is different from each other, and the multistage solenoid valve having a predetermined number of stages is used in combination. It is characterized by the ability to adjust the amount of water in multiple stages more than the number of stages. According to this configuration, the amount of water can be adjusted in multiple stages, so that the cleaning can be performed with the minimum amount of water required depending on the region to be cleaned. In addition, the amount of water can be adjusted in multiple stages from a small amount of circulating water using only the solenoid valve with the least amount of circulating water to a large amount of circulating water using all the solenoid valves all at once.

  In the car wash machine having the above-described configuration, when the water volume ratio is 1: 2: 4 and the water volume of the first stage solenoid valve is L, the water volume of the second stage solenoid valve is 2L, The amount of water in the three-stage solenoid valve is 4L, and the amount of circulating water can be adjusted in seven stages from L to 7L by combining these amounts of water. According to this configuration, the total amount of water can be adjusted in seven stages from L to 7L, so that it is possible to perform cleaning with the optimum amount of water depending on the region to be cleaned.

  According to the present invention, in the car wash machine configured as described above, the spray nozzle includes a swing nozzle. According to this configuration, it is possible to spray cleaning water and liquid containing cleaning agent while swinging this spray nozzle, and spray it uniformly over a wide area, so that wasteful consumption of cleaning water is suppressed and further water saving effect is achieved.

  Embodiments of the present invention will be described below with reference to the drawings. Moreover, the same code | symbol is used about the same component and detailed description is abbreviate | omitted suitably.

  The car wash machine WA of the present embodiment is a car wash machine that performs a car wash using compressed air, water, and a liquid agent while relatively moving the car wash machine body and the vehicle to be cleaned in the front-rear direction, and is a schematic side view of FIG. As shown in FIG. 4, a tank storage unit 50 for storing a plurality of liquid storage tanks (not shown) for storing various liquid agents such as detergents and waxes, and cleaning water and liquid agents from the respective liquid storage tanks via an electromagnetic valve or the like. The distribution piping part 51 to distribute is provided. Moreover, it is provided with a plurality of injection nozzles for injecting cleaning water and various liquid agents, for example, an injection nozzle 10A for mainly injecting cleaning water, and an injection nozzle for injecting cleaning water mainly mixed with various liquid agents 10B.

  The injection nozzle 10 (10A, 10B) is configured to be capable of high-pressure spraying in order to exhibit a higher cleaning effect. Moreover, it is set as the structure which can respond also to the low pressure washing process which performs car washing with a smaller amount of water corresponding to a normal car wash. For this reason, the car wash machine WA of the present embodiment is capable of handling both the high pressure washing process and the low pressure washing process using the injection nozzle 10 (10A, 10B). For example, the injection nozzle 10A is used for high-pressure spraying for pre-rinse, shampoo, and wax, and the injection nozzle 10B is used for high-pressure spraying for final rinse.

  In general, in a car wash machine configured to perform high-pressure spraying in addition to a normal car wash, both a low-pressure pump and a high-pressure pump are installed. However, in this embodiment, in order to reduce equipment costs, Only the pump P is installed so as to correspond to both the high-pressure washing process and the low-pressure washing process. In addition, as the high-pressure pump P, for example, a vertical multistage spiral pump can be used.

  For this purpose, the car wash machine WA according to the present embodiment supplies water from the water tank 70 to the water distribution part 71 via the water distribution pipe 73 and supplies the wash water from the water distribution part 71 to the distribution pipe part 51 provided in the car wash machine main body 1. At the same time, the water distribution section 71 is provided with a high-pressure pump P and a water amount adjusting means 72 so as to be adjusted to an appropriate amount of water corresponding to the high-pressure washing step and an appropriate amount of water corresponding to the low-pressure washing step. That is, in the low-pressure washing process, the amount of water is made smaller than that used in the high-pressure washing process via the water amount adjusting means 72.

  Then, water is supplied from the water amount adjusting means 72 to the distribution pipe section 51 via the water distribution cable K1. The water distribution cable K <b> 1 is introduced into the upper rear surface of the car wash machine body 1 from a support guide 62 provided on an upper part of a tilting pole 60 that is erected on the support leg 61 so as to be tiltable. The water distribution cable K <b> 1 is installed by being slackened in advance so as to correspond to the traveling movement of the car wash machine body 1.

  The water amount adjusting means 72 is composed of a multi-stage type electromagnetic valve, and by using a combination of this multi-stage type electromagnetic valve with a predetermined number of stages, it is possible to adjust the water quantity in multiple stages more than the number of stages. For example, it is possible to adjust the amount of water in multiple stages more than the number of stages of the multistage type by combining the circulation water quantities by the respective solenoid valves as different water quantity ratios.

  In other words, the amount of circulating water by the multistage solenoid valve is set to a different water volume ratio, and the amount of circulating water using all the solenoid valves at the same time is very small, from the small amount of circulating water using only the solenoid valve with the least circulating water volume. The water volume can be adjusted in multiple steps up to a large volume of water. With this configuration, the amount of water can be adjusted in multiple stages, so that the cleaning can be performed with the minimum amount of water required depending on the region to be cleaned. That is, even when the high-pressure pump P is used, the amount of water can be reduced to the same level as when washing is performed using the low-pressure pump, and as a result, the same cleaning effect as when washing is performed using the low-pressure pump.

  For example, in this embodiment, as shown in FIG. 2, the water amount adjusting means 72 provided with a three-stage solenoid valve is used. Further, when the water volume ratio of these solenoid valves is 1: 2: 4 as shown in FIG. 3 and the first stage solenoid valve V1 has the water volume L, the second stage solenoid valve V2 has the water volume of 2L. The third stage solenoid valve V3 is a multi-stage type with a water volume of 4L. With such a configuration, as shown in FIG. 4, the first-stage solenoid valve V1, the second-stage solenoid valve V2, and the third-stage solenoid valve V1 are obtained from the water amount L by the first-stage solenoid valve V1. Since the amount of water can be adjusted in seven stages up to a total of 7 L by the electromagnetic valve V3, it is possible to perform cleaning with the optimum amount of water depending on the region to be cleaned.

  That is, the amount L of water by the first stage solenoid valve V1, the amount of water 3L (L + 2L) by simultaneously using the first stage solenoid valve V1 and the second stage solenoid valve V2, and the first stage electromagnetic valve. By using the valve V1 and the third stage solenoid valve V3 at the same time, the amount of water 5L (L + 4L), the first stage solenoid valve V1, the second stage solenoid valve V2, and the third stage solenoid valve V3 Can be adjusted to an appropriate amount of water by appropriately combining three-stage solenoid valves, such as a water amount of 7 L (L + 2L + 4L).

  As described above, the car wash machine WA according to the present embodiment supplies water to the high-pressure washing process and the low-pressure washing process for washing through the water distribution unit 71 having the same high-pressure pump P and the water amount adjusting means 72. Therefore, the equipment cost can be reduced as compared with a car wash machine including both the high pressure pump P and the low pressure pump. Moreover, since the high-pressure pump P is provided, high-pressure cleaning that exhibits a high cleaning effect can be performed. Further, since the water amount adjusting means 72 is provided, it is possible to perform cleaning with the same amount of water as that of the conventional low pressure pump by adjusting to a predetermined amount of water necessary for cleaning, even if the high pressure pump P is used. Sufficient water saving effect can be achieved. That is, it is possible to obtain a car wash machine WA that can achieve a high cleaning effect and a sufficient water-saving effect and can further reduce the equipment cost.

The vehicle sensor 8 includes a photoelectric sensor, an ultrasonic sensor, and the like, and detects the vehicle to be cleaned CA that enters the car wash machine body 1. Moreover, in order to detect the vehicle shape of the to-be-cleaned vehicle CA, the vehicle shape detection part (not shown) which consists of an area sensor which consists of a transmissive | pervious photoelectric sensor may be provided in the entrance part of the car wash machine main body 1.

  An operation panel 7 is disposed on the front surface on one side of the car wash body 1. The operation panel 7 has the same operation buttons as the remote panel 7A, and accepts a car wash and sets car wash conditions by the operation of a user who gets off the vehicle to be cleaned CA.

  As setting of the car wash conditions, buttons for adding shampoo, waxing, water repellent coat, etc. to the water wash are provided on the operation panel 7 and the remote panel 7A. There are also buttons for high-grade shampoo, high-grade wax (for example, glazing coating), high-grade water repellent coating, special coating, etc., and a button for selecting a high-pressure washing process. In addition, equipment setting buttons such as front guard, fender pole, door mirror, rear wiper, and no applicable equipment are provided.

  The car wash machine WA of the present embodiment is a car wash machine that performs a car wash of the vehicle to be cleaned CA while relatively moving the car wash machine body 1 and the vehicle to be cleaned CA in the front-rear direction. In addition to the process, a high-pressure washing process can be performed.

  That is, the first and second water purification nozzles 11 and 13, the first and second detergent nozzles 12 and 15, the water repellent coating nozzle 14, and the wax nozzle 16 are each provided with a plurality of injection nozzles, and high pressure is applied to these injection nozzles. The spray nozzle 10 (10A, 10B) that can be sprayed is used.

  Therefore, when a high-pressure washing process is selected via the operation panel 7 or the remote panel 7A, an appropriate amount of water is set according to each process, and the water amount adjusting means 72 is driven and controlled according to the setting.

  For example, when pre-cleaning is performed by high-pressure spraying, the first water purification nozzle 11 is used, and a plurality of injection nozzles 10 provided in the upper, middle, and lower portions are simultaneously opened to open a large amount of solenoid valves V1, V2, and V3. Supply water. When low pressure cleaning is selected, the solenoid valves V1 and V2 are opened to supply a medium amount of water to the plurality of injection nozzles 10 provided at the upper part, middle part, and lower part of the first water purification nozzle 11.

  Thus, since it was set as the structure which supplies water via the water distribution part 71 which has the same high pressure pump P and the water quantity adjustment means 72 to a some injection nozzle, it is a high-pressure and a large quantity to the some injection nozzle 10 (10A, 10B). High pressure cleaning is possible by supplying water, and low pressure cleaning is also possible by supplying a small amount or medium amount of water to the plurality of jet nozzles 10 (10A, 10B).
