OPERTATING METHOD FOR STEAMER WITH COMPLEX FUNTION}

The present invention relates to a method for controlling a steam machine having a complex function for washing, and more specifically, to wash and implement a complex function such as steam car wash, air mixed steam car wash, and air car wash in one steam machine. It relates to a steam machine control method with a combined function.

Since the present invention relates to a related device for washing a hand in a self-cleaning car wash, a detailed description of the automatic car washing device using an automatic car wash is omitted.

The inventor of the present invention has previously filed a multi-purpose brush for automobile car wash (hereinafter referred to as "steam car wash hand brush") and filed a patent application No. 10-1528639-0000 and patent application No. 10-2017-0156854.

The washing method is to wash the car by either water washing or steam washing method, and after washing, it is necessary to wipe off water (moisture) or water stains on the car body with a rag, or to wipe off or dust the engine room or the room. In this case, the borrower has to work physically using a suitable cleaning tool, there is a problem of fatigue and hard work.

However, self-cleaning car washes are equipped with convenient facilities such as guns or guns that can spray water or steam for effective and efficient car wash, but the above-mentioned facilities are not suitable for a series of subsequent work performed after a new car. Does not help

For example, the above-described steam car wash hand brush can be used efficiently only when it is provided with steam produced by a steamer. However, since most car wash steamers produce steam only, the steam car wash hand brush is used only in winter when the temperature drops below zero. There is a problem that is difficult to use.

The inventors of the present invention have been devised to solve the above-mentioned problems, and there are remarkable achievements, and the present invention is proposed through the present invention.

The purpose of the present invention is to wash the water, as well as steam car wash, air wash and hot air using moisture or water stains, using the car wash to remove dust or foreign matter, such as washing the car wash a complex function that can be used at any time To provide a steamer control method.

Another object of the present invention is to provide a method for controlling a steam machine having a combined function for washing a car which can shorten steam generation time and improve steam pressure.

As a solution for solving the object of the present invention,

The controller determines whether the preheat mode button, the water car wash mode button, the steam car wash mode button, or the air car wash steam car wash mode button arranged on the control unit are selected.

When the preheat mode button is selected, the controller supplies power to the heating element to heat the heater housing when the temperature sensed by the temperature sensor attached to the heater housing is lower than the temperature set for the heater housing, and conversely, the sensing temperature is the heater. When the temperature is higher than the set temperature of the housing, the power supply to the heating element is cut off to continuously control the heater housing to be maintained at the set temperature range.

When the steam car wash mode button is selected, if the sensing temperature of the temperature sensor is within the set temperature range, the controller drives the feed water pump to supply water to the steam chamber to discharge steam, and conversely, the temperature of the heater housing is set. If it falls below one temperature range, it controls to supply power to the heating element.

When the air-mixed steam car wash mode button is selected, the controller supplies power to the air supply means and the water supply pump at the same time when the sensing temperature of the temperature sensor corresponds to the temperature range of the set heater housing. By supplying the water transported by the steam chamber and, on the contrary, when the sensing temperature is lower than the set temperature, all the heating wires wound around the heating element and the spacer are applied to control the temperature of the heating housing to be maintained in the set temperature range.

When the hot air mode is selected by the air car wash mode button, the controller supplies power to the air supply means and the heat-generating heating element adopted among the blower and the hot air heater or the hot air heater, and controls the temperature of the heater housing to be maintained within the set temperature range.

When the cold wind mode is selected, the controller controls to supply power to the blower or the hot air fan to supply air into the air passage.

When the water wash mode button is selected, the controller is characterized in that the power is supplied only to the water supply pump.

The present invention can be washed only with steam produced by the heated heater housing by supplying water into the water supply pump into the steam chamber, and steam the water supplied by the hot water and the water supply pump heated by the air supply means. At the same time, it can be washed by feeding into the chamber. ③ Only hot air heated by the air supply means can be supplied to the steam chamber to wash with hot air. ④ Air can be washed by supplying cold air to the steam chamber through the air supply means. ⑤ It can wash the water by supplying water into the steam chamber with water supply pump without heating the heater housing, so it is possible to control complex functions with a single car wash steamer.

In addition, the present invention can shorten the steam generation time by mixing the water and air into the steam chamber, it is possible to reduce the amount of use of the steam there is an effect that can significantly reduce the amount of waste water generated.

As described above, the present invention has an effect that can be used in four seasons by implementing a single car wash function such as steam car wash, water car wash, hot air (air) car wash, steam and air mixed car wash.

Hereinafter, with reference to the accompanying drawings a preferred embodiment of the steam generator control method having a combined function for washing according to the present invention will be described in detail. Prior to the description, the main configuration of the steamer according to the present invention will be described first.

1 and 2, Figures 1 and 2 is a perspective view and an exploded perspective view of a steam control method with a composite function of the present invention, the steamer 100 with a composite function is the main body having a cover 101 ( 110).

The main body 110 has an operation mode as shown in FIG. 9 on the front surface 112a (preheat mode button a, steam car wash mode button b, air mixed steam car wash mode button c, air car wash mode button ( d), the water washing mode button (e)] is provided with an operation unit 151 for selection and the rear side 112b is coupled to the water supply pipe, the water outlet pipe and the power inlet cable (not shown), the body 110 A heater 130, a controller 150 having a circuit control function, and a feed water pump 111 are embedded therein.

3 and 6 are perspective views illustrating the heater described above, FIG. 5 is a longitudinal sectional view of the heater, and FIG. 6 shows another example of the use of the heater shown in FIG. 5. One longitudinal section view.

The heater 130 is a lump form heater housing 130a made of aluminum (Al) or copper material (Cu) having excellent thermal conductivity, and a heat-transmitting heating element 133 having a built-in heating wire coupled to the heater housing. ) (See FIG. 7).

In FIG. 4, reference numeral 133a denotes a coupling hole into which the above-described heating element 133 is inserted, reference numeral 134 denotes a steam chamber for rapidly heating and vaporizing water, and in FIG. 5, reference numeral 103a denotes a housing cap and 138 denotes an air passage. 131a is a connecting member for hermetically connecting the steam chamber 134, and 139 is a connecting tube for connecting the connecting member connected to the duct to the inlet.

The heating element is heated by a built-in heating wire is connected to the power supply terminal of both ends.

Although the cross section of the heater housing 130a is illustrated in the drawings, the shape of the heater housing 130a is merely an exemplary embodiment of the heater 130, and the shape thereof is not particularly limited.

The heater housing 130a described above may further include air supply means capable of selectively supplying air (hot air / cold air) into the steam chamber 134.

As an example of employing the air supply means, a duct 131 having an air passage 131a spaced a predetermined distance around the heater housing 130a may be further coupled, and a nonflammable spacer may be disposed in the air passage 131a space. In the drawing, a heating wire (not shown in the drawing) is installed on the wire, and the air blower 140 is coupled to the surface of the duct 131 so as to pass through the air passage 131a. The air heated through the hot air is supplied into the steam chamber 134 by combining the hot air fan (not shown in the drawing) with the air passage 131a so as to be supplied into the air or into the hot air fan (not shown). It can also be implemented to supply.

The hot air provided by the air supply means may preheat the heater housing 130a together with a heating element during the initial start-up, or maintain the temperature of the heated heater housing 130a during use.

One side of the air passage is connected to communicate with the steam chamber, the other side is closed so that the outside air flows into the steam chamber via the air passage when the blower is operating.

The method of blowing hot air into the steam chamber 134 through the hot wire and the blower wound around the nonflammable spacer can heat the air in the air passage 131a and the heater housing 130a at the same time by the heat generated from the hot wire. By heating the housing 130a more quickly there is an advantage that can reduce the steam generation time.

On the other hand, the method of supplying hot air or air to the steam chamber 134 through a hot air fan with a built-in hot wire is a slow rate of heating the heater housing (130a) by hot air, but heated hot It is useful for quickly drying or removing water (moisture) or water stains by blowing the heated hot air into the steam chamber 134, and is useful for removing dust or foreign matter when blowing air in an unheated state.

The above air supply means may be connected to a hose or tube connected between the feed pump and the steam chamber. In this case, the effect of preheating the heater housing by the hot air heated in the duct cannot be expected, but by incorporating air into the steam chamber together with the water, the vaporization rate can be increased, and a smaller amount can be washed. can see.

Meanwhile, the heater housing 130a rapidly heated by the heating element 133 is discharged in a vaporized state while the water introduced through the feed pump 111 connected to the steam chamber 134 passes, and the steam chamber in the vaporization process. Alkali chemicals contained in water accumulate on the inner wall of 134 in a scale form, and as a pipeline is gradually occluded, it acts as a fatal defect on the reliability (unavailability) of the product.

The present invention may further employ a customs member 137 for customizing the pipeline of the steam chamber 134 in order to overcome the pipeline blockage problem as described above.

Customs member 137 employed in the present invention,

The screw shaft 134d is rotated in the steam chamber 134 by using the flow rate of the water supplied by the feed water pump 111 or the airflow introduced by the aforementioned hot air blower or blower 140.

More specifically, as shown in FIG. 7, the tubular member 137 has a screw shaft 134b having a length similar to that of the steam chamber 134 while having an outer diameter slightly smaller than that of the steam chamber 134. In the rotatable installation of the 134d in the steam chamber 134, the rotation is coupled to one side of the shaft 134d to rotate the shaft 134d by a flow rate or air flow formed in the steam chamber 134. The bearing 134c is provided with a wing 134a and a passage (not shown) through which a fluid or gas is passed while being fixed to an inner diameter of the steam chamber 134 so as to receive the shaft 134d to rotate.

Since the above-mentioned blockage of the pipeline is intensified more than when a large amount of steam is continuously manufactured, the customs member 137 can be more reliably adopted in the steam manufacturing apparatus 100 designed for this purpose. have.

The above-described customs member 137 is a screw 134b shaft 134d is rotated as described above by the flow rate or air flow flowing along the steam chamber 134, so that the pipeline of the steam chamber 134 continues to be customised. Even if manufactured, the problem of clogging the pipe line can be reliably prevented.

As described above, the present invention supplies the water to the water supply pump 111 into the steam chamber 134 to wash only with steam generated by the heated heater housing 130a, or the hot water heated by the air supply means described above. The water supplied by the air and the water supply pump 111 may be simultaneously supplied into the steam chamber 134 to wash the car, and only the hot air heated by the air supply means is supplied to the steam chamber 134 to wash the hot air. It is also possible.

One side of the steam chamber 134 described above is coupled to the water inlet 135 connected to the water supply pump 111 and the hose connected to the steam car wash hand brush (not shown) as shown in FIGS. The outlet 136 is coupled to each other.

The above-described selection of the car wash method may be operated in a manner selected by control selectively by the operation unit 151 and the controller 150.

Hereinafter, a control method according to an operation mode of a car wash steamer will be described in more detail with reference to FIG. 9.

According to the present invention, the driving mode according to the steam car control with the composite car washing function according to the present invention includes a preheating mode button (a), a steam car washing mode button (b), a mixed air car washing mode button (c), and an air car washing mode button (d). The user may select one of the water car wash mode buttons (e) to operate.

The above-described preheating mode button (a) is an operation mode for controlling the temperature to preheat the heater housing 130a in advance or to keep it at a constant temperature. For example, the multipurpose steamer 100 according to the present invention is continuously operated in a self-cleaning car wash. When not in use, it refers to the operation mode for maintaining the temperature of the heater housing 130a so that subsequent users can use immediately, the above-described steam car wash mode button (b) is the user of the steam to wash the car using steam Refers to the operation mode, the air-mixed steam car wash mode button (c) refers to the operation mode of the steamer that can mix and wash air when the user washes the steam, the air car wash mode button (d) is a hot air or cold air It refers to the operation mode of the steamer to dry or remove the moisture (water) or water stains on the surface of the vehicle body faster, and the water wash mode button (e) Not as a heated says the operation mode of the Steamer to mulsecha.

The control method of the controller for each operation mode will be described in detail.

When the preheat mode button (a) of the operation unit 151 is selected, the controller 150 displays the temperature sensed by the temperature sensor (not shown) attached to the heater housing 130a with respect to the heater housing 130a. When the temperature is lower than the set temperature, power is supplied to the heating element 133 to heat the heater housing 130a. On the contrary, when the sensing temperature is higher than the setting temperature of the heater housing 130a, the power supplied to the heating element 133 is cut off. The electrical circuit is controlled so that the temperature of the heater housing 130a continues to generate heat in the set temperature range.

When the steam car wash mode button (b) of the operation unit 151 is selected, the controller 150 drives the water supply pump 111 to operate the steam chamber 134 when the sensing temperature of the temperature sensor corresponds to the set temperature range. When water is supplied into the water and, on the contrary, when the temperature of the heater housing 130a falls below the set temperature range, the heating circuit 133 supplies power to control the electrical circuit to operate the heating element so that the temperature of the heater housing 130a is increased. Done.

When the air mixing steam car wash mode button (c) of the operation unit 151 is selected, the controller 150 controls the air supply means and water supply when the sensing temperature of the temperature sensor corresponds to the temperature range of the heater housing 130a. Supplying power to the pump 111 at the same time to continuously supply the hot air and hot water transported by the feed water pump 111 into the steam chamber 134, on the contrary, if the sensing temperature is lower than the set temperature heating element 133 The electric circuit is controlled so that the temperature of the heating housing 130a rapidly reaches a set temperature range by applying power to all the heating wires wound around the spacers.

When the above-described mixed air car wash mode button (c) is selected, water and air are supplied together in the steam chamber 134 under the control of the controller 150 to pass through the steam chamber. Since the air is heated faster when it comes into contact with the surface, the vaporization rate of the water, that is, the steam production time, is shortened, and the exhaust pressure of the steam is rapidly increased.

When the air washing mode button (d) of the operation unit 151 is selected, the controller 150 applies power to the air supply means and the heat generator 133 employed among the blower and the hot air fan 140 having the hot wire or hot wire. The temperature of the heater housing 130a is controlled to be maintained within a set temperature range.

At this time, the action of the air supply means and the heating element 133, if the temperature sensed by the temperature sensor is lower than the set temperature range of the heater housing 130a, the controller controls to supply power to the air supply means and the heating element 133 If the temperature is higher than the set temperature, the power is cut off.

The air car wash mode is further subdivided into hot air and cold air mode. When the hot air mode is selected, the controller 150 supplies power to the hot wire and the blower to heat air passing through the air passage 131a to supply the steam passage. In selecting the cold wind mode, only the blower is operated so that air without heating is supplied into the steam chamber.

The set temperature of the heater housing 130a is set to different temperature ranges during the hot air mode and the steam car wash mode of the above-described air car wash mode. That is, the hot air temperature in the air car wash mode (d) is set to a temperature range that does not burn, and the set temperature of the heater housing 130a in the steam car wash mode (b) is set to a temperature at which steam can be produced. It is important.

When the water washing mode button e is selected, the controller 150 may apply power only to the water supply pump 111 to wash the water using the water passing through the steam chamber 134.

When air is supplied to the steam chamber through the air passage 131a as described above, the air is supplied in a heated state by latent latent heat to the heater housing 130a, so that the temperature of the water is increased, thereby reducing the steam generation rate. It works.

As described above, the present invention provides a driving mode suitable for washing the car by selectively controlling the car wash method, such as water washing, steam washing, washing with air, washing with hot air or cold wind, dust washing or drying by wind, etc. You can switch and drive, so you can always use the steamer.

In addition, the present invention can generate steam more quickly by the preheating function and the temperature holding function, and by reducing the steam generation time by mixing water and hot hot air into the steam chamber together, increasing the exhaust pressure of the steam Can be washed with less steam (reduced waste water).
