TECHNICAL FIELD
The present invention relates generally to a tub equipped with a sauna system, a water jet system, at least one massage & scrub disk assemblies, a tub clean system and a media center.
BACKGROUND OF THE INVENTION
It is well known that a walk-in bathtub is safe and comfortable. It allows the user to walk into and out of the bathtub without a risk of slips and falls. Its back place has been raised and created a built-in seat, some water jet nozzles have been installed on the tub walls. The user feels safe and comfortable during sitting on the built-in seat and getting a hydraulic massage by the water jet. Although the walk-in bathtub has these advantages mentioned above, it still has some faults. Firstly, it is only attractive to the users with old ages or physical disabilities, but the independent persons are not interested in these functions. Secondly, the walk-in bathtub makes a bathing very expensive because the bathing consumes lots of warm water, especially, used in some water shortage countries and areas. Thirdly, its open structure causes some problems too, for example, much heat loses. The users, especially those who are in poor health, easily catch a cold. These above reasons badly affect the commercialization of the walk-in bathtub.
BRIEF SUMMARY OF THE INVENTION

DETAILED DESCRIPTION OF THE INVENTION
FIG. 1 shows a perspective view of a walk-in bathtub with an outward swinging side door in accordance with the prior art;
Referring now to FIG. 2, FIG. 2 shows a perspective view of the multi-functional personal hygiene system with a left side door in a closed position with a preferred embodiment of the present invention. Similarly, FIGS. 3A˜3E show a perspective views of the multi-functional personal hygiene system with a left side door in an opened position with a preferred embodiment of the present invention.
In the example shown (FIG. 2), the multi-functional personal hygiene system mainly comprises the tub 1 where the user takes a sauna, a shower, a bath and a massage, an access door 20 with a door lock 21, a cover assembly which consists of a sliding cover 13, an eversible cover 14 and an immovable cover 4 (best shown in FIGS. 9A˜9G), a massage & scrub disk assembly 16 (best shown in FIGS. 10A˜10C), a support frame 17, the sauna system 65 (shown in FIG. 9E) that is adapted to supply the user a sauna and auxiliary heat the warm water in the tub 1, the water jet system 18 that is adapted to supply the user a shower or bath and a hydraulic massage, a cold water valve 2, a hot water valve 3, a hand held shower head 12, a front apron 19, six control buttons 5, 6, 7, 8, 10 and 11 (best shown in FIG. 9G), a leakage current circuit breaker 15 and the media center 9. It is important that the leakage current circuit breaker 15 is installed in the multi-functional personal hygiene system. It will switch off the whole hygiene system and protect the user in case of leakage of electricity.
Unlike prior art designs, the present invention allows the user to sit down on the built-in seat before entering the tub 1, then turn his or her body safely about 90 degrees and move the legs into the tub 1. In another word, sitting-in is safer than walking-in for the invalids.
As shown in FIGS. 2, 3A, 3C and 3D, for the user to easily operate the multi-functional personal hygiene system of the embodiment of the present invention, six buttons are installed on the top of the multi-functional personal hygiene system, they are named as POWER 10, TUB CLEAN 11, BATH MODE 8, MASSAGE 7, WATER JET 6 and SAUNA 5 (best shown in FIG. 9G). When the user wants to use the multi-functional personal hygiene system, he should do the following operations.
First of all, the power button 10 has to be pressed down, once this button is pressed down, the media center 9 has been started. An instant temperature value inside the tub 1 has been detected by a temperature sensor 38 (shown in FIGS. 3E and 12) and shown on the screen. For a new user, he/she can read some information in the media center 9, such as some information about the sauna, shower, bath and massage. Of course, he/she may read a tub manual in the media center 9 before doing the next operations.
Secondly, the user may press down the tub clean button 11 if he wants to clean the tub 1. Before pressing down this button, he has to close the access door 20, turn the handle 21 and lock the access door 20. The tub clean system is an auxiliary system that cleans the whole hygiene system automatically, saves the tub cleaning labour, and avoids a cross infection between different users, and is controlled by a circuit controller 63 (as shown in FIG. 9E). Once this button 11 is pressed down, the circuit controller 63 will close a drain solenoid valve 39 (normally opened) and open the water inlet solenoid valve 36 (normally closed, as shown in FIG. 3E) at once. The water, coming from a cold water line 35 and a hot water line 34 (as shown in FIG. 3E), passes a faucet 32 (as shown in FIG. 3C), and enters the tub 1 immediately. The water inlet solenoid valve 36 will close when a water level reaches to a predetermined level, the water level is controlled by a water level gage 40 (as shown in FIG. 3E). The tub clean system will not start if the sliding cover 13 and the eversible cover 14 do not cover the tub 1 completely because a magnetic switch 42 (shown in FIG. 3D) is off. The magnetic switch 42 is controlled by the eversible cover 14, the magnetic switch 42 will be on when the eversible cover 14 covers the tub 1 completely and be off when the eversible cover 14 opens. Once the magnetic switch 42 is on and the water level reaches to the predetermined water level, the pump 18 (as shown in FIGS. 2, 3A, 3C-3E) will start immediately. The water, mixed with some soap and antiseptic liquids, goes to all of the water jet nozzles with a wide spraying angle 22 (as shown in FIG. 3A) and the hydraulic massage water jet nozzles 26 (as shown in FIG. 3B), is jetted everywhere of the tub 1. The water jet will last a predetermined time, this time is controlled by the circuit controller 63 (as shown in FIG. 9E). The tub clean process will finish when this process lasts a predetermined time. The circuit controller 63 stops the pump 18, and opens the solenoid drain valve 39 (as shown in FIG. 3E). Conversely, as shown in FIG. 1, the walk-in bathtub with the prior art does not have this function because of shortage of the cover assembly shown in the present invention.
Thirdly, the user may press down a bath mode button 8 when he wants to take the bath. Usually, the users, especially the young users, just simply take a shower. But sometimes, they want to take the bath too, especially the old and infirm members in their family like to take the bath. So it is necessary that the multi-functional personal hygiene system is equipped with both a shower mode and a bath mode. Once the bath mode button 8 is pressed down, the multi-functional personal hygiene system will be on the bath mode. The bath mode will be cancelled and the multi-functional personal hygiene system goes back to the shower mode when the bath mode button 8 is pressed down again.
Fourthly, if the user wants to take the sauna, he may press down the SAUNA button 5 (shown in FIGS. 2, 3A, 3C, 3D and 9G). The sauna system includes a steam maker or a hot-air fan 65 (as shown in FIG. 9G) that is located in the immovable cover 4, a pipe 37 (as shown in FIG. 3E) that transports some steam or hot air into the tub 1, the sauna button 5 and the circuit controller 63 (as shown in FIG. 9E). After sitting on the built-in seat, closing and locking the access door 20 by turning the handle 21, the user can press down the SAUNA button 5 to start his sauna, then pulling out the sliding cover 13 and closing the eversible cover 14, the steam maker or hot-air fan 65 begins to work right away. The steam or hot air will go into the tub 1 along the pipe 37 (shown in FIG. 3 E) that connects the steam maker or hot-air fan 65 and the faucet 32 (as shown in FIG. 3C) of the tub 1. A temperature will be detected by the temperature sensor 38 and shown on the screen, and this temperature goes up instantly until reaching to a predetermined temperature, then the circuit controller 63 keeps this temperature. The user can finish his sauna by means of pressing the SAUNA button 5 again. It is very important that when the sauna system is working, the water jet button 6, the bath mode button 8, and the tub clean button 11 absolutely cannot work even if they have been pressed down carelessly.
As for the water jet system, it mainly comprises of the water inlet solenoid valve 36 (as shown in FIG. 3E), a water level gage 40 (as shown in FIG. 3E), the pump 18, the water jet nozzles with a wide spraying angle 22 (as shown in FIG. 3A), the hydraulic massage water jet nozzles 26 (as shown in FIG. 3B), a regulating valve 23 (as shown in FIG. 3A), a filter 30 (as shown in FIG. 3C), the circuit controller 63 (as shown in FIG. 9E), a faucet 32 (as shown in FIG. 3C), the temperature sensor 38 (as shown in FIG. 3E) and the solenoid drain valve 39 (as shown in FIG. 3E). In the example shown in FIG. 3B, four or more hydraulic massage water jet nozzles 26 are installed on the back wall of the tub 1 according to the present invention. These hydraulic massage water jet nozzles 26 jet the warm water on the user's body and legs, this process is similar to a hydraulic massage. The water jet nozzles with a wide spraying angle 22 are mounted on the wall of the closed space, and spray the warm water fog on the user's skins and aim at moisturizing and cleaning the skins.
Now, the user opens the access door 20, sits down on the built-in seat, turns his body 90 degrees. After sitting on the built-in seat, he closes and locks the access door 20 by turning the door lock handle 21. The user can press down the WATER JET button 6 to start his shower. If he wants to take a bath, he should press down the BATH MODE button 8 before pressing down the WATER JET button 6. Once the WATER JET button 6 is pressed down, the user may pull the sliding cover 13 out of the immovable cover 4 and close the eversible cover 14. The magnetic switch 42 will be on when the eversible cover 14 covers the tub 1 completely. The circuit controller 63 closes the solenoid drain valve 39, and opens the water inlet solenoid valve 36 immediately. After water passes the cold water line 35 and hot water line 34 (shown in FIG. 3E) and mixes, passes the water inlet solenoid valve 36 and a faucet 32 (shown in FIG. 3C), finally arrives in a tub pool. The cold water valve 2 and the hot water valve 3 is connected to its associated supply line 35 and 34 and controlled by the user to open and allow the water flow through the lines 35 and 34, or to close and stop the water flow through the lines 35 and 34. If the temperature sensor 38 (as shown in FIG. 3E) detects that the temperature of the water through the faucet 32 exceeds a predetermined temperature, the circuit controller 63 will shut up the water inlet solenoid valve 36 immediately, and open the drain solenoid valve 39, the media center 9 will show “alarm” on the screen. The filter 30 (as shown in FIG. 3C) is located at the bottom of the tub 1, before the inlet of the pump 18. The pump 18 is situated under the built-in seat and on a pedestal. Filtered water passes the pipe line 33 (as shown in FIGS. 3D and 3E) and arrives at the inlet of the pump 18. Some suction pipe lines connect the water jet nozzles to the outline 41. The pump 18 will start when the water level gage 40 detects that the water level arrives at a predetermined level, meanwhile, the warm water is jetted out of all the water jet nozzles. The regulating valve 23, which connects the inlet and outlet of the pump 18 by means of the pipe line, is adapted to adjust the pressure of the water jet nozzles. When the user feels that the water pressure is too high, he may open the regulating valve 23. Some of water coming from the pump will go back directly to the inlet of the pump. When he feels that the water pressure is too weak, he may close the regulating valve 23. The user may get a desirable jetting strength by turning the regulating valve 23. The temperature sensor 38 detects the water temperature and shows it on the screen 9. When this temperature drops, the circuit controller 63 will start the steam maker or hot-air fan 65 to make some steam or hot air, the steam or hot air will be sent into the tub pool and heats the water. When the water temperature goes up to the predetermined temperature, the circuit controller 63 will switch off the steam maker or hot-air fan 65, so the water temperature is always kept at the determined temperature. The magnetic switch 42 (as shown in FIG. 3D) is adapted to pause the multi-functional personal hygiene system, the magnetic switch 42 will be on when the sliding cover 13 and the eversible cover 14 cover the tub 1 completely, and off when the eversible cover 14 is pushed away. The water jet process may recover from the pause point instead of starting from the beginning when the sliding cover 13 and the eversible cover 14 cover the tub 1 completely again. If the user wants to finish the water jet, just opens the eversible cover 14 and press the WATER JET button 6 again. Once the water jet button 6 is pressed again, the solenoid drain valve 39 (shown in FIG. 3E) will be opened immediately by the circuit controller 63 (as shown in FIG. 9E) and the pump 18 will be switched off by the circuit controller 63. All the water in the multi-functional personal hygiene system will be drained completely. Similarly, it should be mentioned that all the operation on the SHOWER mode can be used on the bath mode.
As shown in FIGS. 2, 3A˜3E, a hand held shower head 12 is equipped on the top of the multi-functional personal hygiene system in accordance with a preferred embodiment of the present invention. This hand held shower head 12 is usually used for washing the user's head and face. Sometimes, it is used for cleaning the user's body with the clean water after the user takes a shower or bath with soap water as well. It is simply used for cleaning the tub 1 as well. It should be mentioned that when the water jet system is working, the sauna button 5, the bath mode button 8 and the tub clean button 11 absolutely cannot work even if they have been pressed down carelessly. The massage button 7 does or does not work according to the user's desire during the water jet system working.
