Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a freeze prevention device for a car washer,

The present invention relates to a freeze prevention device for a car washer, and more particularly, to a freeze prevention device for a car washer, which is constructed in an automatic or self-washer, and removes fluid remaining in a pipe for spraying water and detergent for washing, And to provide a new type of freeze prevention device capable of performing stable and stable washing work.

As a car washing facility, there is an automatic car washer which automatically injects water and detergent into the car when the automobile to be washed, and the operation of the washing means such as the washing brush and the injection of the compressed air to remove moisture, And a self-washing machine that carries out the cleaning operation directly.

Such a car washer requires spraying high pressure cleaning water for removing foreign substances and detergent, regardless of automatic and self, and spraying detergent to clean the surface of the vehicle in which the foreign matter is removed.

In order to spray the washing water and the detergent, the washing water and the detergent of the washing water and the detergent tank are moved through the supply line by the pumping means such as a compressor, and the washing water and the detergent are sprayed through the spray nozzle.

Such clean water and detergents can be a major problem in seasons when the outside temperature is always maintained, such as in spring, autumn, and summer, but in the season when the outside temperature falls to below zero, such as during the winter season, The water or the detergent is frozen and the nozzle or the supply pipe is damaged. As a result, it is difficult to perform normal washing in the daytime.

In order to solve such a problem, many freeze prevention devices for car washes have been developed and used. For example, in one example, hot water heated by a heating means is flowed to a supply pipe or nozzle, or all pipes are heated by using a heating wire To prevent the pipe from being frozen.

2, the compressor and the supply line are connected to blow the water and the detergent remaining in the supply line and the nozzle to the outside of the supply line and the nozzle to prevent freezing.

Registered Utility Model No. 20 - 0335460 - 0000 Utility Model Application No. 20 - 1997 - 0027897 Patent Application No. 10 - 1996 - 0064113 Patent Application No. 10 - 2004 - 0088654

In the case of one example in which the conventional technique is applied, since the period of the winter season is long in Korea, and the length of the supply pipe constituting the car was long, when the hot wire is wound around the entire supply pipe, However, since it takes a lot of facility cost and maintenance cost, it results in an excessive cost of installation and maintenance of the car washer, which causes an increase in the economic burden.

Particularly, a portion of the supply pipe and the nozzle are maintained in close contact with the frame. However, since most of the supply pipe and the nozzle are free to move from the frame, when the car wash is carried out with the hot wire covered, Frequently interferes with the frame and damages the heat ray.

If there is damage to the hot wire, there is a fear of a fire due to a short circuit of the hot wire in the winter, especially during a night when the manager does not reside, and there is a high possibility of a safety accident caused by a short circuit. The nozzle can not be kept warm, so that it can not prevent the phenomenon of being frozen in the end, and the cost for repairing the broken wire also becomes excessive.

In the two cases, the compressed air is strongly supplied to the supply pipe by using the compressor, and the cleaning water and the detergent remaining in the supply pipe or the nozzle are discharged to the outside to prevent freezing. However, It is difficult to remove the washing water and the detergent from the supply line and the nozzle, thus making it difficult to escape from the concern of freezing.

In order to solve this problem, compressed air is injected into the supply line and the nozzle periodically. However, since the compressed air itself contains water, water is always left in the supply line and the nozzle, and water and detergent falling through the nozzle There are various problems such as causing a safety accident that users slip in the process of car washing in the day while maintaining the state of being frozen on the floor.

Accordingly, it is an object of the present invention to provide a washing water supply pipe, a detergent supply pipe, a washing nozzle, and a washing water remaining in the detergent nozzle when the car is not washed in winter, And a freeze prevention device capable of preventing the detergent from being sucked in vacuum and being damaged by freezing, wherein the freeze prevention device comprises a wash water recovery pipe connecting the wash water supply pipe in front of the pumping means and the wash water tank, A detergent recovery pipe connected between the supply pipe and the detergent tank; a suction pump provided in the middle of the wash water recovery pipe and the detergent recovery pipe; and control means for intermittently or periodically activating the suction pump;

By preventing the freezing of the car washes, it is possible to provide maintenance easiness while improving the life and durability of the car washer. Also, it prevents the bottom from freezing due to washing water and detergent while preventing waste of washing water and detergent, It is possible to accomplish a goal that can be done.

The present invention relates to a washing water supply pipe, a detergent supply pipe, a cleaning nozzle and a detergent nozzle which constitute a car washer, a cleaning nozzle and a detergent nozzle, By freezing in the winter season, especially during nighttime, it is possible to prevent the washing water supply pipe, the detergent supply pipe, the washing nozzle and the detergent nozzle from being damaged, It is possible to easily manage the car wash while preventing a safety accident beforehand.
