Description

[Detailed Description of the Invention] [Industrial field of application] The idea is to collect hot water discharged to prevent freezing of car wash machines at coin car wash areas in winter and keep it at an appropriate temperature for reuse. The present invention relates to a water discharge circulation device for saving water and saving energy and improving sales efficiency in a car wash machine.

[Prior Art] Conventionally, this kind of thing is as follows.

Car wash machines that use a hand-held wash nozzle to wash the car generally have a car wash hose connected to the main body or operation unit and a wash nozzle connected to the other end. It is long enough to work around the vehicle.

As described above, the cleaning nozzle and car wash hose are exposed to the outside air, and the cleaning water remaining in the car wash hose or in the cleaning nozzle may freeze during the winter. At that time, hot water was discharged from the main body washing water tank, and the discharged hot water was discarded to the ground as it was.

Further, in order to replenish the discarded hot water, it was necessary to newly supply water from a water source to the water tank and convert the heat into hot water by a heat source such as a boiler.

In addition, as one of the existing technologies, the warm water supplied to prevent freezing is stored in a recovery tank installed at a low position below the ground, etc. by gravity fall, and is re-supplied to the water tank by a pump. Is.

[Problems to be Solved by the Invention] The conventional techniques described above have the following problems.

As a problem from the above-mentioned prior art, the hot water discharged to prevent freezing of the car wash machine in winter is discarded at the car wash after being supplied. This wastes water.

Furthermore, in order to replenish the discarded hot water, it is necessary to newly replenish the water from the water source and heat-convert this into hot water with a boiler or the like, which requires a large amount of heat.

Furthermore, the method of collecting hot water in a recovery tank provided under the ground, which is an existing technology, and then re-supplying it to the water tank with a pump, requires a space because the recovery tank is installed under the ground, It is difficult to move.

In addition, when detergent water, wax, etc. remaining on the washing nozzle or car wash hose gets mixed in the recovery tank, a filtration device is required before sending it to the water tank to prevent mixing in these water tanks. Becomes complicated, and equipment costs, construction costs, etc. rise, and it is difficult to relocate.

Furthermore, the discharged hot water travels on the ground and reaches the recovery tank by natural fall, so that sand, pebbles, and the like are easily mixed therein, which easily causes freezing and pump trouble.

The present application has been made in view of such problems of the conventional technique, and an object thereof is to solve the above-mentioned problems.

[Means for Solving the Problem] In order to achieve the above object, the present invention is as follows.

That is, the present application is a storage for recovering discharged water or hot water in a freeze prevention structure in which a minute amount of water or warm water is discharged from the car wash nozzle in a car washing machine such as a coin car wash where the car is washed from a hand-held cleaning nozzle. The container is attached to the main body, and the container is a waterproof circulation device that is connected to a pipe for supplying cleaning water to the cleaning nozzle by a pipe line and supplies water or hot water collected in the container again to the cleaning nozzle. .

In this case, the piping that constitutes the circulation system can be passed through a heat source for heating the wash water of the main body or a tank of wash water that has been turned into warm water by heating.

[Operation] Next, the operation of the present invention will be described.

First, the hot water discharged from the washing nozzle 18 for preventing freezing in the winter is accumulated in the container 25, passes through the pipe 20, the filter 28, and the pipe 23, and is controlled by the pump 9 under the control of the solenoid valve 16. , Car wash hose 19 and car wash nozzle 1
8 is re-supplied.

The warm water collected in the container is re-supplied to the car wash hose 19 and the cleaning nozzle 18 via the pipe 20, the filter 28, and the pipe 23, while the pipe 20 and the filter 2 are supplied.
8. The water is circulated to the boiler 17 by the water discharge circulation pump 10 via the pipe 21 and is appropriately heated here, and then supplied again to the container 25 via the pipe 22.

Further, a water level gauge 2 installed between the pipe 20 and the pipe 22.
In No. 6, the water level equilibrium state is obtained with the storage container 25 at a certain point, but due to a trouble such as a mistake in storing the cleaning nozzle 18 in the storage device 25, and a relatively slight pipe breakage,
When the water content of the circulation meter decreases, this equilibrium is broken and the water level drops. This lowering of the water level is detected by the lower limit level sensor 27, and a signal is sent to the solenoid valve 15 which is synchronized with the lower limit level sensor 27, so that the hot water in the water tank 1 is piped under the control of the solenoid valve 15. 20 via
To restore the total amount of water in the circulation system to a constant amount.

[Embodiment of the Invention] A description will be given with reference to the drawings.

FIG. 1 shows a structural model of a car washer that employs the water discharge circulation device according to the present invention.

As a typical principle of the coin car wash machine in the coin car wash area, water from the water tank 1 and the concentrated detergent tank 2 and the concentrated detergent are supplied to the warm detergent tank 3 by the pump 7 to be appropriately mixed and kept warm, and the detergent water. Stored as. The detergent water in the warm detergent tank 3 is sent to the washing nozzle 18 via the car wash hose 19 by the pump 8 while being controlled by the flow rate of the electromagnetic valve 12.

Here, the water in the water tank 1 is supplied from the water source A, and in order to keep this water at an appropriate temperature, it is converted into hot water by the boiler 17 by using the pump 6.

Further, the water in the water tank 1, the base wax tank 4 and the finish wax tank 5, the base wax and the finish wax are
While being controlled by the flow rates of the solenoid valves 11, 13, 14 respectively, the pump 8 sends the washing liquid to the washing nozzle 18 via the car washing hose 19. Here, in order to prevent freezing in winter, it is necessary to supply hot water to the car wash hose 19 and the wash nozzle 18 at appropriate times.

The water discharge circulation device of the present invention is provided with a container 25 having an appropriate capacity to store hot water discharged at a proper time, and the cleaning nozzle 18 is housed in the container 25 to prevent timely released freezing. The warm water is accumulated in the container 25, and the pipe 20 is connected to the container 25.
