In this regard, many spa facilities for physical and mental relaxation have recently been developed. Among them are various SPAs whose interiors rush streams of water against human bodies to massage and relax someone.

However, here in SPAs usually pure or cyclic water is stormed after the pressure increase against the massage sites of a body. Since you can not control the exit amount of water well, it can lead to pore widening. If the water quality in this case is not good enough, bacteria can penetrate through expanded pores in the body. In connection with this, you can not relax well. Even worse, it would cause skin diseases or other diseases.

As a result, some people buy SPA tubs that can be fitted with ozone to enjoy SPA at home. By inserting ozone into water stream, the cleanness of the water can be guaranteed. In addition, the strength of the water flow and the type of massage by the water can be changed according to the needs of the user, whereby relaxation can be realized in different degrees.

To operate the water supply system 10 after the SPA mode becomes the first solenoid valve 14 through the control module 11 opened while the second solenoid valve 16 through the control module 11 is closed. In connection with this, the water escapes through the hydrotherapy nozzle 132 and thus generates output current Wo2. Conversely, the water supply system 10 through the switching unit 20 set to the micro bubble mode, then the first solenoid valve 14 closed and the second solenoid valve 16 opened, such that of the ozone generating module 15 produced ozone is added to the water flow, the one from the engine 12 sucked water through the microbubble generator 131 is performed. As a result, the output current Wo1 is generated.

It should be noted that the engine 12 Running water stream on the route to the hydrotherapy nozzle 132 as opposed to on route to the micro bubble generator 131 a much smaller resistance is exposed. When opening the first solenoid valve 14 Therefore, most of the water flow through the hydrotherapy nozzle 132 Running while only a little water flow through the microbubble generator 131 exit.

The water supply system 10 also has a pressure switch 17 on that with the engine 12 and the control module 11 connected is. The pressure switch 17 serves to detect the outlet pressure of the engine 12 , This will determine if there is water flow through the engine 12 flows. Is shown that the engine 12 has not sucked any water, then sends the pressure switch 17 the control module 11 a signal to the engine 12 to put out of service. In this way is caused by idle combustion of the engine 12 to avoid.

The water supply system 10 It is also equipped with at least one drain valve 191 . 192 provided that to a pipeline of the water supply system 10 connected. Using the drain valve 191 the water left behind in the pipeline is first removed before the actual water outlet. Only after that will water supply through the water supply system 10 performed in SPA mode or the microbubble mode.

According to the embodiment, water is supplied cyclically. The water source 40 can be designed as a bathtub. The one from the water outlet module 13 generated output current Wo1, Wo2 is forwarded to a bathtub, the engine 12 is also operated by the water in the bathtub. In this way, the cyclical running of water is possible. The water outlet of the water source 40 is with a filter 41 provided to the engine 12 to filter conducted water. In this way, the blocking of the pipeline by hair or foreign bodies is avoidable.

The water supply system 10 is still with a filter detection unit 42 provided to determine if the filter 41 exactly at the water outlet of the water source 40 is arranged. It detects that the filter 41 not at the water source 40 is provided, then a signal to the control module 11 passed through the water supply system 10 is shut down to eventually protect the piping of the system.

Compared to 1 indicates the control module 11 in 2 a processing unit 111 , a WS / DC converter unit 112 , a leak detection unit 113 , an overload detection unit 114 and an electromagnetic control unit 115 on.

The processing unit 111 serves here for signal processing and for controlling all components in the water supply system 10 and is connected to the first solenoid valve 14 , the ozone generation module 15 , the second solenoid valve 16 , the pressure switch 17 , the WS / GS converter unit 112 , the leak detection unit 113 , the overload detection unit 114 and the electromagnetic control unit 115 connected.

The WS / GS converter unit 112 is between the AC power source 30 and the processing unit 111 arranged. Using the WS / GS converter unit 112 becomes that of the AC source 30 provided current energy converted into direct current, the operation of the processing unit 111 serves.

The leak detection unit 113 is to the AC power source 30 and the processing unit 111 connected and used for leakage detection. If the output current does not correspond, for example, to the input current, then there may be a leakage at the power line. This leakage is from the leak detection unit 113 detected, then a signal is sent to the processing unit 111 forwarded. In this case, the power is interrupted to protect the power lines and thus increase the safety in use.

The overload detection unit 114 is also with the AC power source 30 and the processing unit 111 connected to determine if the of the AC power source 30 incoming power is overloaded. If so, a signal is sent to the processing unit 111 forwarded. In this case, power will be cut off and all components will be disabled to avoid damaging the power lines.

The electromagnetic control unit 115 is to the overload detection unit 114 and the processing unit 111 connected and is under control of the processing unit 111 , The overload detection unit 114 sends the electromagnetic control unit 115 Electricity to the engine 12 to get started, such that the engine 12 Water from the water source 40 can suck.

Referring to 2 has the water supply system 10 furthermore a regulation unit 18 on and is connected to the second solenoid valve 16 and the engine 12 connected. Here, the regulating unit 18 be designed as a Venturi tube to the amount of ozone from the second solenoid valve 16 to regulate. The regulation unit 18 receives the flow of water from the engine 12 and mix it appropriately with the ozone. The mixed with the ozone water flow is thus back to the water inlet of the engine 12 transported. That way, the engine can 12 the mixed with the ozone water flow to the water outlet module 13 hand off.

In 3 For example, electrical connections are drawn with thinner lines, water supply lines with thicker lines, while the unavailable connections are marked with dashed lines.

Receives the processing unit 111 one from the switching unit 20 emitted signal to switch the water supply system 10 in SPA mode, the water left in piping is drained through the drain valve 191 . 192 drained. Subsequently, the electromagnetic control unit 115 to drive the motor 12 through the processing unit 111 regulated, such that the engine 12 Water from the water source 40 sucks. At the same time, the first solenoid valve 14 through the processing unit 111 open. According to the embodiment, most of the water flow when opening the first solenoid valve 14 to the hydrotherapy nozzle 132 , This is because the water flow on the route to the hydrotherapy nozzle 132 a much smaller resistance than on the way to the microbubble generator 131 is exposed. Through the hydrotherapy nozzle 132 the water pressure is increased so that the stronger output current Wo2 is produced and discharged. Due to the small amount that can cause the microbubble generator 131 running water does not affect the effect of SPA.

It should be noted that the pressure switch 17 , the filter detection unit 42 , the leak detection unit 113 and the overload detection unit 114 in the SPA mode of the water supply system 10 permanently in operation. It is found that the water outlet pressure of the engine 12 not enough or the filter 41 not at the water outlet of the water source 40 is arranged, or is leakage or

Current overload detected, then the current through the processing unit 111 interrupted. In this case, the engine becomes 12 put out of order to ensure increased safety during use.

Regarding 4 is an embodiment of the water supply system according to the invention 10 shown schematically in the microbubble mode. In the illustrated embodiment, the switching unit 20 switched sequentially. That is, in order to switch to the microbubble mode, it must first be set to the SPA mode. Only then can the water supply system 10 by pressing the switching unit again 20 be switched to the micro bubble mode. For this reason, the water left behind before being adjusted to the microbubble mode by the drain valve 191 . 192 already drained. In connection with this, a repeated water outlet is no longer necessary. Will the water supply system 10 through the switching unit 20 set to the micro bubble mode, then the first solenoid valve 14 through the processing unit 111 closed, such that of the engine 12 generated water flow through the microbubble generator 131 is omitted.

At this time, the ozone generation module 15 put into operation. By opening or closing the second solenoid valve 16 by means of the processing unit 111 may the ozone be added to the water stream or not. By the regulation unit 18 (Venturi tube), the amount of ozone can be regulated, that of the engine 12 supplied water stream is mixed with ozone. Subsequently, the water stream mixed with ozone is returned to the water inlet of the engine 12 transported. In this way, water flow with ozone through the engine 12 to the microbubble generator 131 of the water outlet module 13 be forwarded to generate the output current Wo1. This ensures the cleanliness of the water. By means of the micro-bubbles, the skin and the pores can be covered, whereby foreign bodies are excluded. In this case, the body can be cleaned properly. At the same time, anions are generated when the microbubbles burst in the water, so that the user can relax properly.

By means of the water supply system of a hydrotherapy system according to the invention, the water cleanliness and the safety during use can be increased. By means of the motor according to the invention, the user can choose either SPA or microbubble mode as needed. This ensures increased applicability of the hydrotherapy system according to the invention.

The foregoing description illustrates the embodiments of the invention and is not intended to limit the claims. All equivalent changes and modifications that may be made by those skilled in the art in accordance with the description and drawings of the invention are within the scope of the present invention.
