The present invention relates to a device for removing moisture and water in a steam spray hose of a steam generator for preventing freeze in winter, and a method thereof.

In general, a steam generator pumps the water in a water tank with a water pump and pumps it to a heater to generate steam, and then stores the generated steam under reduced pressure in the steam tank at a certain pressure, and is then removably connected to the steam spray pipe. Steam is sprayed through a steam gun installed in the hose. When such a steam generator is applied to a car washing of a vehicle, since it is used outdoors, a problem of freezing occurs in the winter season in winter.

That is, after using the steam generator, moisture and water remaining in the steam spray hose remain. In the cold winter season, moisture and water remaining in the steam spray hose freeze, and if you want to use it afterwards, the piping is blocked and it cannot be operated.

As a background technology of the present invention, as Korean Patent Registration No. 10-1764776, an'air steam device having a tank preheating structure for preventing freezing' has been proposed. This is a steam device that sprays steam to remove oil residues and dirt from the automobile engine.The housing body is provided with a receiving room and a drawer inside, an operation room at the top, a caster at the bottom, and a handle on one side.

The residual material suction means 50 sucks moisture and water remaining in the steam injection hose 32 when the use of steam is stopped or stopped. The residue suction means 50 may be a suction pump or a vacuum suction device.

As shown in FIG. 2, the residue suction means 50 may be configured to be connected to the air compressor 40 through a supply pipe 52 for suction operation so as to operate by compressed air supplied from the air compressor 40. In this way, when the residue suction means 50 is connected to the air compressor 40 and driven, a separate driving energy is unnecessary. At this time, a control valve 55 for operating a vacuum suction device is installed in the supply pipe 52 for suction operation.

Here, when the residue suction means 50 becomes a vacuum suction device, compressed air is introduced to generate negative pressure inside, thereby causing vacuum suction.

In addition, as shown in FIG. 2, the residual material suction means 50 is preferably connected to the water tank 12 through the residual material recovery pipe 54. Accordingly, the water sucked from the residue suction means 50 is recovered into the water tank 12 via the residue recovery pipe 54.

The operation of the moisture and water removal device in the steam injection hose of the steam generator for preventing freezing in winter will be described with reference to the flow chart of FIG. 3.

First, when the power to the steam generator 10 is turned on, the water in the water tank 12 is pumped by the water pump 14 to be pumped to the heater 16 to generate steam, and then the generated steam is brought to a constant pressure. As a result, the steam is stored under reduced pressure in the steam tank 20 and the steam is injected through the steam gun 30 installed in the steam spray hose 32 together with compressed air (S11).

Thereafter, when it is confirmed that the steam generator is stopped or the power is turned off (S12), the supply of compressed air and steam is cut off (S13) by blocking the control valve 63 for supplying steam.

Then, when the use of the steam generator 10 is stopped or stopped (S13), a step (S14) of confirming a freeze prevention mode (use in winter) is performed. The freeze protection mode means, for example, sensing an outside temperature and recognizing it as a freeze protection mode when the temperature is below a certain temperature. This may be accomplished by electrically connecting a temperature sensor (not shown) capable of sensing the outside air temperature to the control unit 100.

Then, when the freezing protection mode is confirmed, the control valve 62 for inhaling residues is opened, and the residual intake means 50 is turned on to forcibly suck and remove moisture and water remaining in the steam injection hose 32 (S15). ). When the residual material suction means 50 is turned on, negative pressure is generated, and moisture and water remaining in the steam injection hose 32 are quickly sucked in.

In addition, water sucked from the residue suction means 50 may be recovered into the water tank 12 through the residue recovery pipe 54 of FIG. 2.

Then, when it is confirmed that the suction means 50 has been operated for a set time (S16), the residue suction means 50 is turned off (S17).

Then, the air supply control valve 61 is opened, the air compressor 40 is turned on, and the air is supplied to the steam injection hose 32 to dry the inside of the steam injection hose 32 (S18). . At this time, heat to be generated from the heater 73 installed on the hot air supply pipe 71 is supplied to the steam spray hose 32.

As described above, according to the present invention, the moisture and water remaining in the steam injection hose are firstly sucked in after steam is used in the winter season, and the second hot air compressed air is used to quickly dry and remove it, thereby preventing freezing.
