2. Description of the Related Art
More and more modern people have been becoming more and more vulnerable to increasing psychological stresses. Thus, they choose to turn to leisure centers for hydrotherapy including muscle massage by applying pressurized water flow onto human body.
However, the quality of water flow used in the spa leisure center is hardly controllable. If the water used for muscle massage is of inferior quality, such as exceptional high intensity of bacteria, people might not achieve their original goal when deciding to receive some hydrotherapy.
Moreover, to improve the quality of water, a spa bathtub which is capable of adding ozone into water in order to improve the water quality has been introduced. However, safety concern arising out of the usage of electrical device in an environment that is so close to water has not been thoroughly addressed.
Because of the aforementioned problems, the present invention discloses a water supply apparatus with anti-bacterial functions capable of providing multiple operating modes associated with hydrotherapy.
To achieve the mentioned purposes, a water supply apparatus of a hydrotherapy device is disclosed according to the present invention. The system includes a water outlet module, a motor, a control module, a first magnetic valve, an ozone module, a second magnetic valve, and a pressure switch.
The water outlet module has a micro-bubble generator and a spa nozzle, for outputting a water flow. The motor is coupled with the water outlet module, for retrieving a water from a water source and providing the water to the water outlet module. The control module is coupled with the motor, an AC power source, and a switching unit. The control module receives a switching signal from the switching unit, and an electric power transmitted from the AC power source for driving the motor according to the switching signal. And the first magnetic valve couples with the control module, the motor, and the water outlet module and is controlled by the control module for determining whether to transmit the water from the motor to the spa nozzle of the water outlet module.
Additionally, the ozone module is coupled with the control module, for generating ozone and disinfecting the water. The second magnetic valve couples with the control module and the ozone module, and is controlled by the control module for determining whether to transmit the ozone. And, the pressure switch is coupled with the control module and the motor, for detecting the pressure of water outlet of the motor. If the pressure of the water outlet of the motor is low, which is indicative of the motor does not successfully retrieve the water, the control module may stop the motor from working.
Furthermore, the control module as described above is controlled by the switching unit, in order to determine whether to use the spa nozzle or the micro-bubble generator to output the water flow. Thus, by operating the switching unit, operation modes of the water supply apparatus could be determined.
And, the control module can further include a leakage detection unit and an overload detection unit, in order to detect a power leakage and a power overload. Additionally, the water supply apparatus may have a throttle unit coupled with the second magnetic valve and the motor, for controlling the output of the generated ozone. Thus, the appropriate amount of the ozone can be added into water in order to disinfect the water.
Moreover, the water supply apparatus can further include at least one drain valve, which is coupled with the motor and the water outlet module, for draining the water remaining in the pipes of the water supply apparatus. A strainer is installed associated with the water source for filtering the water to the motor. Thus, the strainer can prevent the pipes of the water supply apparatus from being clogged with hairs or dirt. And, the water supply system can further include a strainer detection unit for detecting whether the strainer is installed at the water source properly.
The water supply apparatus of the present invention can output good quality water by adding the ozone. And, the water supply apparatus is capable of detecting the power leakage and the power overload, enhancing the safety when the water supply apparatus is in use. Furthermore, the water supply apparatus can switch among at least two operation modes.
For further understanding of the invention, reference is made to the following detailed description illustrating the embodiments and examples of the invention. The description is only for illustrating the invention, not for limiting the scope of the claim.
The drawings included herein provide further understanding of the invention. A brief introduction of the drawings is as follows:

The water outlet module 13 includes a micro-bubble generator 131 and a spa nozzle 132. The micro-bubble generator 131 is configured to add micro-bubbles into water for outputting water flow Wo1. The spa nozzle 132 is for outputting pressurized water flow Wo2. By the water outlet module 13, the water supply system 10 can output at least two different water flows.
The motor 12 is coupled to the control module 11, the water outlet module 13, and the first magnetic valve 14. The motor 12 is configured to retrieve water from a water source 40, and transmits the retrieved water to the micro-bubble generator 131 or the spa nozzle 132 according to a control signal received from the control module 11. The control module 11 is also configured to transmit the power required for the motor 12 to function to the motor 12.
The ozone module 15 is coupled to the control module 11 and the second magnetic valve 16, for generating ozone that is capable of disinfecting the water flows. The control module 11 can control whether to transmit the generated ozone from the ozone module 15 to the water inlet of the motor 12 by opening or closing the second magnetic valve 16.
The control module 11 is the control center of the water supply apparatus 10 that controls signals, and is coupled to the motor 12, the first magnetic valve 14, the ozone module 15, the second magnetic valve 16, and the pressure switch 17. The control module 11 is further coupled to an alternating current (AC) power source 30 and a switching unit 20. The AC power source 30 is for providing requisite power to water supply apparatus 10, and the switching unit 20 is for setting the operation modes of the water supply apparatus 10.
Users can use the switching unit 20 to adjust the operating mode of the water supply apparatus 10 to choose between micro-bubbles and spa. The operation modes of the water supply apparatus 10 may at least include a micro-bubble mode and spa mode. After the control module 11 receives a switching signal from the switching unit 20, the control module 11 then controls the first magnetic valve 14 and the second magnetic valve 16 according to the switching signal in order to switch among the operation modes.
For example, if the spa mode is selected the control module 11 will then turn on the first magnetic valve 14 but turn off the second magnetic valve 16. Thus, the water retrieved by the motor 12 can be transmitted to the spa nozzle 132 and the pressurized water flow Wo2 is outputted. On the other hand, if the micro-bubble mode is selected the control module 11 will then turn off the first magnetic valve 14 but turn on the second magnetic valve 16. Thus, the ozone generated by the ozone module 15 can be added into the water retrieved by the motor 12, and the water flow Wo1 will be outputted through micro-bubble generator 131.
It is worth noting that the water supply apparatus 10 is configured to create a smaller flow resistance associated with the water to the spa nozzle 132 when compared with that associated with the water to the micro-bubble generator 131. Therefore, when the first magnetic valve 14 is turned on most of the water transmitted from the motor 12 flows to the spa nozzle 132. As such, the water supply apparatus 10 does not require another magnetic valve between the motor 12 and the micro-bubble generator 132.
Additionally, the water supply system 10 can further include a pressure switch 17 which is coupled to the motor 12 and the control module 11. The pressure switch 17 is for detecting the pressure of the water outlet of the motor 12, in order to ensure that the motor 12 retrieves the water successfully. If the detection of the pressure of the water outlet indicates that the motor 12 does not retrieve the water properly, the control module 11 then stops the motor 12 from operating. Thus, the consumption of the water may be reduced when the water retrieval of the motor 12 is not as desired while the integrity of the whole operation of the water supply apparatus 10 may be maintained.
Moreover, the water supply apparatus 10 may further include drain valves 191 and 192 coupled to water pipes of the water supply apparatus 10. After the operation mode of the water supply apparatus 10 is selected, the drain valve 191 and 192 may drain the water remaining in the water pipes before the operation of the water supply apparatus 10.
The water may be recycled in the water supply apparatus 10. More specifically, the water source 40 may come from the water in a bathtub, so that the water flows Wo1 and Wo2 that are sent to the bathtub may serve as the water source from which the motor 12 could retrieve before preparing the water to the water outlet module 13.
Considering the water may be recycled, the water supply apparatus 10 may further include a strainer 41 associated with the water source 40. With the strainer 41, the water flows may be filtered before being recycled as the water source 40. Consequently, dirt and/or hairs from the water flows may be stopped from entering into the pipes in order to minimize the occurrence of clogging. Additionally, the water supply system may include a strainer detection unit 42, for determining whether the strainer 41 is installed at the water source 40 or not. If the strainer 41 is not installed properly, the strainer detection unit 42 then sends a signal to the control module 11 for stopping the water supply apparatus 10 from operating.

The processing unit 111 is for processing signals and controlling other components of the water supply apparatus 10′. The processing unit 111 is coupled to the first magnetic valve 14, the ozone module 15, the second magnetic valve 16, the pressure switch 17, the AC-DC conversion unit 112, the leakage detection unit 113, the overload detection unit 114, and the electromagnetic control unit 115.
The AC-DC conversion unit 112 is disposed between the AC power source 30 and the processing unit 111. The AC-DC conversion unit 112 is for converting the power provided by the AC power source 30 into a DC power, and sending the DC power to processing unit 111. Thus, the processing unit 111 may function properly with the requisite electrical power.
The leakage detection unit 113 is coupled to the AC power source 30 and the processing unit 111, for detecting a power leakage. For instance, if the input power is not equal to the output power, the power leakage may have taken place in the circuit. When the detection result indicates the occurrence of the power leakage, the leakage detection unit 113 then sends a signal to the processing unit 111 for cutting off the power supply.
The overload detection unit 114 is coupled to the AC power source 30 and the processing unit 111, for detecting a power overload. If the magnitude of power provided from the AC power source 30 is over a threshold value, the overload detection unit 114 sends a signal to the processing unit 111 for cutting off the power supply. Detecting the power leakage and power overload may provide the water supply apparatus 10′ with additional protection/safety measures.
The electromagnetic control unit 115 is coupled to the overload detection unit 114 and the processing unit 111. The electromagnetic control unit 115 is controlled by processing unit 111, and is configured to receive the power to drive the motor 12.
Additionally, the water supply apparatus 10′ further includes a throttle unit 18 coupled to the second magnetic valve 16 and the motor 12. The throttle unit 18 may be a Venturi tube for adjusting the amount of ozone added into water. The throttle unit 18 receives the water from the motor 12, mixes a proper amount of ozone with the received water, and then sends the water back to the water inlet of the motor 12. Thus, the motor 12 may output the ozonized water to the water outlet module 13.

When the processing unit 111 receives the switching signal indicative of a selection of the spa mode, the drain valve 191 and 192 may drain the remaining water in the pipe lines, and the processing unit 111 then controls the electromagnetic control unit 115 to drive motor 12, in order to retrieve the water from water source 40. At the same time, the processing unit 111 turns on the first magnetic valve 14. Because the flow resistance associated with the water to the spa nozzle 132 is configured to be smaller than that associated with the water to the micro-bubble generator 131, when the first magnetic valve 14 is turned on most of the water flows to the spa nozzle 132. And thus the pressurized water flow Wo2 is outputted by the spa nozzle 132 with very little amount of water flowing to the micro-bubble generator 131.
When the water supply system 10′ operates in the spa mode, the pressure switch 17, the strainer detection unit 42, the leakage detection unit 113, and the overload detection unit 114 are still operating. Therefore, if the retrieved water is not enough, the strainer 41 does not installed at the water source 40 properly, or power leakage or power overload occurs, the processing unit 111 will cut the power off and deactivate the motor 12 for safety concern.

Specifically, the ozone module 15 is configured to operate when the water supply apparatus 10′ is in the micro-bubble mode. At the same time, the processing unit 111 controls the second magnetic valve 16 for determining whether to add the generated ozone into water. Additionally, the throttle unit 18 is for adjusting the amount of ozone added into the water, and for mixing the water with the generated ozone. The ozonized water is then transmitted to the water inlet of the motor 12, so that the motor 12 can send the ozonized water to the micro-bubble generator 131. Thus, the micro-bubble generator 131 generates the micro-bubbles with the ozonized water, and outputs the water flow Wo1. In doing so, the water supply apparatus 10′ may enhance the quality of the water flow Wo1.
As described above, the quality of the water flow and the safety can be improved through the water supply apparatus of the present invention. Furthermore, by providing spa mode and micro-bubble mode through one single motor the water supply apparatus of the present invention could satisfy increased demands from the consumers.
