This disclosure relates generally to apparatus for a jet massage. More particularly, the disclosure relates to a hydro-therapeutic bathtub jet massage device.
Jet massage devices are often used in a bathtub, hot tub (e.g., spa hot tub) or a whirlpool. Many conventional jet massage devices are built-in to the bathtub or the hot tub or a whirlpool. Other jet massage devices are heavy add-ons to a bathtub, a hot tub or a whirlpool, that when added to an already built bathtub, hot tub or whirlpool, becomes part of its permanent fixture. There is a desire to have overall portability and lightweight features of the jet massage device with no permanent attachment to the bathtub, bathroom floor or walls. Also, it would be desirable for a jet massage device which can be moved or stored away easily when not in use. It would be desirable for a jet massage device to be used with one bathtub and then moved to a different bathtub conveniently. In some conventional jet massage devices, when a jet massage device is used for an extended period of time, the motor may overheat. Thus, it would be desirable to have a jet massage device include an efficient form of heat dissipation.
The following presents a simplified summary of one or more aspects in order to provide a basic understanding of such aspects. This summary is not an extensive overview of all contemplated aspects, and is intended to neither identify key or critical elements of all aspects nor delineate the scope of any or all aspects. Its sole purpose is to present some concepts of one or more aspects in a simplified form as a prelude to the more detailed description that is presented later.
Disclosed is jet massage device. According to one aspect, a jet massage device including a pump unit submersible in liquid; an electronic unit electrically coupled to the pump unit, wherein the electronic unit includes a programmable component for determining one or more of the following of the pump unit: power ramp, voltage level, current level, water flow volume, water flow rate or frequency pulsing of a water stream; and a spa jet assembly, coupled to the pump unit and the electronic unit for delivering the water stream.
Advantages of the present disclosure may include overall portability and light weight of the jet massage device, ability to be moved or stored easily, and using the tube or pool water to cool the pump motor by aiding in heat dissipation since the pump unit may be entirely or partially submerged in water.
It is understood that other aspects will become readily apparent to those skilled in the art from the following detailed description, wherein it is shown and described various aspects by way of illustration. The drawings and detailed description are to be regarded as illustrative in nature and not as restrictive.
The detailed description set forth below in connection with the appended drawings is intended as a description of various aspects of the present disclosure and is not intended to represent the only aspects in which the present disclosure may be practiced. Each aspect described in this disclosure is provided merely as an example or illustration of the present disclosure, and should not necessarily be construed as preferred or advantageous over other aspects. The detailed description includes specific details for the purpose of providing a thorough understanding of the present disclosure. However, it will be apparent to those skilled in the art that the present disclosure may be practiced without these specific details. In some instances, well-known structures and devices are shown in block diagram form in order to avoid obscuring the concepts of the present disclosure. Acronyms and other descriptive terminology may be used merely for convenience and clarity and are not intended to limit the scope of the present disclosure.
While for purposes of simplicity of explanation, the methodologies are shown and described as a series of acts, it is to be understood and appreciated that the methodologies are not limited by the order of acts, as some acts may, in accordance with one or more aspects, occur in different orders and/or concurrently with other acts from that shown and described herein. For example, those skilled in the art will understand and appreciate that a methodology could alternatively be represented as a series of interrelated states or events, such as in a state diagram. Moreover, not all illustrated acts may be required to implement a methodology in accordance with one or more aspects.
In one example, the electronic unit 110 includes a manual control 112, for example, to turn it ON and OFF. In one example, the one or more electrical cables 120 connect the electronic unit 110 with the pump 140. The one or more electrical cables 120 may be housed in a flexible housing tube 122. The ends of the flexible housing tube 122 may include one or more fittings 124 (e.g., adapter or conduit fittings). The pump unit 140 is located inside a pump housing 142. In one example, the flexible housing tube 122 is connected through the pump housing 142 via a fitting 124. In one example, the pump housing 142 includes an output hole 144 and/or one or more small holes 146. The quantity of the output hole 144 and/or small holes 146 are design choices which may vary according to many factors, including but not limited to, the type of pump unit being used. In one example, the pump unit 140 includes a strainer 148 and one or more foam paddings 149. In one example, the strainer 148 is a mesh sponge or a filter foam. In one example, the pump unit 140 is entirely or partially submerged in water, and the water can cool the pump motor 147 by aiding in heat dissipation.
In one example, the jet massage device 100 of the present disclosure is a portable, hand-held hydro-therapeutic bath tub jet massage device. In one example, it can be controlled with the use of a remote control 130. The jet massage device 100 may be portable and lightweight and may allow a user to safely massage any part of the user's body while in any bathtub. An additional feature is an adjustable spa jet air-water stream, with freedom of motion. Although the jet massage device 100 is described herein as being used in a bathtub, one skilled in the art would understand that the jet massage device may be used in any pool of water or liquid and be within the scope and spirit of the present disclosure.
In one example, a programmable power supply (e.g., programmable DC power control circuit) is used. For example, the programmable power supply may pulse at different frequencies, “ramps of power”, or provide any variation in voltage level, and therefore water flow volume or rate, provided by a solid-state, programmable IC, as long as the “ramps” or pulses of power do not generate excessive transient currents in the pump motor 147 or control circuit. In one example, electronic circuit elements, familiar to those skilled in the art, for controlling and regulating excess voltage and current transients or surges may be integrated into a control circuit of the jet massage device.
In one aspect, the pump unit 140 is a 12 V submersible bilge pump unit which may be resting or floating in a water-filled bathtub. The pump unit 140 may not need to be anchored to the bathtub. It submerges and floats on its weight. In another example, the pump unit 140 may be anchored to the bathtub, for example, through the use of suction cups, hooks, screw, etc. One skilled in the art would understand that there are many types of fasteners that may be used to anchor the pump unit 140 to the bathtub without affecting the scope and spirit of the present disclosure. Thus, other types of fasteners (though not specifically mentioned herein) may be used without affecting the scope and spirit of the present disclosure.
In one aspect, the jet message device 110 includes a spa jet assembly 170. The spa jet assembly 170 may include two input holes: a first input hole is connected to an air supply tube 150 and a second input hole is connected to a water supply tube 160. The water supply tube 160 is also connected to the pump unit 140 where water flow is fed from the pump unit 140 to the second input hole of the spa jet assembly 170. In one example, the water supply tube 160 is made of material that allows it to have a flexible quality for bending. The spa jet assembly 110 may also include an output hole 144 where a mixture of water and air exits the spa jet assembly to create a massage sensation on the user's body.
In one example, the amount of air in the mixture of air and water is adjustable to provide a desired proportion of air in the air-water stream exiting out of the spa jet assembly 170. By adjusting the amount of air inputted into the spa jet assembly 170, a user can achieve different massage sensations. This adjustment may be achieved manually by placing a finger over the air supply tube 150 connected as an input to the spa jet assembly 170. In one example, the different massage sensations may be achieved by manually covering portions of an opening of the air supply tube 150. In one example, the water stream is aerated.
Alternatively, the amount of air inputted into the spa jet assembly 170 may be controlled by a mechanical valve that can be manually adjusted by the user, or electro-mechanically by the electronic unit 110, for example, through its programmable circuit. In one example, the mechanical valve is associated with the air supply tube 150.
In one example, the water supply tube 160 connects from the pump unit 140 (which may be resting on the floor of the bathtub or floating in the bathtub) to the second input hole which may be located on the top side of the spa jet assembly 110. The pump unit 140 may be placed in the bathtub with two waterproof electric cables (e.g., a positive lead and a negative lead) connecting it to the power supply, which rests on the bathroom floor outside of the bathtub. In one example, the power supply voltage is 0 to 12 Volts and its voltage output is adjustable. In one example, the AC/DC transformer-power supply 114 comprises of two discrete components: an AC/DC transformer component and a power supply component. It is not necessary for the two discrete components (the AC/DC transformer component and the power supply component) to be housed together. In one example, they are separately housed.
The electronic unit 110 is typically not intended to be submerged in water. However, certain precautions may be added to make the electronic unit 110 waterproof so that in the event of an accident where the electronic unit 110 is submerged into the bathtub filled with water, the user will still be protected from an electrical short circuit. In one example, sealant is used around the exterior boundary of the electronic unit 110 to ensure that it is waterproof. In another example, sealant is also applied to the boundaries of each of the subunits or components within the electronic unit 110. For example, the AC/DC transformer-power supply is waterproofed with a coating of sealant. For example, the power supply is waterproofed with a coating of sealant. For example, the control circuit is a waterproofed with a coating of sealant. For example, the programmable unit is a waterproofed with a coating of sealant. Additionally, waterproofing is applied to the electrical cables and wires that connect the various subunits within the electronic unit 110.
In one example, the two waterproof electric cables may be housed within a protective flexible tube connected between the power supply and the pump unit 140. In one example, the power supply includes a fuse, for example, to protect against an over-current supply (or short) to the pump motor 147 (not shown). The fuse may be housed within a waterproof housing. In one example, the fuse has an automotive-type overcurrent fuse rating based on recommended rating provided by the submersible pump manufacturer. In one example, the power supply is a direct current (DC) power supply with overcurrent and/or over-voltage protection. For example, the DC power supply may be rated for an operating range of approximately between 0V to 19V. In another example, the power supply is an alternating current (AC) power supply with overcurrent and/or over-voltage protection.
In one aspect, isolated electrical grounds of respective alternating current (AC) and direct current (DC) circuits in the power supply provide additional safety protection, following the National Electric Code guidelines for safely powering low-voltage electrical devices in occupied pools, baths and spas.
In one aspect, all the tubes for housing the electrical cables and wires (i.e., flexible electrical conduits) are sealed at all ends with waterproof sealant, such as silicone adhesive or equivalent. In addition, at the end of the flexible electrical conduit, a fitting is installed for coupling the flexible electrical conduits to the pump unit 140. And, at the other end of the flexible electrical conduit, another fitting is installed for coupling the flexible electrical conduit to the electronic unit, for example, to the power supply. One skilled in the art would understand that although in one aspect, the electronic unit 110 includes one or more of the following: power supply, control circuit and/or programmable unit, in another aspect, the power supply, control circuit and/or programmable unit are separately housed and are separate individual units. In one example, the fittings (e.g., adapter fittings, conduit fittings, etc.) are strong enough to allow either the pump unit 140 and/or power supply to be safely lifted by the flexible electrical conduit or tubing without the risk of damaging the electrical connections, cables and wires.
In one example, the pump unit 140 includes a pump motor 147 housed in a pump housing 142. The pump housing 142 may be made of plastic, fiber glass, or an equivalent durable material. The pump housing 142 provides protection for the pump motor 147, such as protection against having the pump motor 147 scrape or bump against the sides of the bathtub as it submerges and floats in the bathtub. In one example, the pump housing 142 is cylindrical in shape and includes a top side and a bottom side. In one example, the bottom side includes an opening for water to enter into the pump motor 147.
In one example, the pump housing 142 includes one or more holes on the top side of the pump housing 142 for pressure equalization, that is, by allowing air bubbles trapped in the pump housing 142 to flow out of the one or more holes. Inside the pump housing 142, foam padding 149 may be placed between the pump motor 147 and the inner wall of the pump housing 149 to provide additional protection for the pump motor 147. The foam padding 149 adds buoyancy. And, the foam padding 149 may reduce audible noise from the pump motor 147. In one example, the foam padding 149 is placed on the top portion of the pump unit 140. The foam padding 149 allows the top portion of the pump unit 140 to float if there is water in the bathtub, and the bottom portion of the pump unit 140 (i.e., the location of the pump motor 147) to be submerged in water for heat dissipation. This is unlike a pump unit that is hooked or attached to the side of the bathtub at a fixed height where the pump unit will only touch the water if the water level in the bathtub is high enough to reach the pump unit.
In one example, the bottom side of the pump housing 142 includes a strainer 148 (e.g., a mesh sponge) to filter the water (e.g., coarse filtration) before the water enters the pump motor 147. In one example, the strainer 148 is held in place under the pump motor 147 at the point where the water enters the pump motor 147. One skilled in the art would understand that there are many ways to hold or secure the strainer in place relative to the pump motor (i.e., within the pump housing) and that any of the ways employed is within the scope and spirit of the present application. For example, clips, other fasteners or Velcro type tapes may be used. Or, in one alternative, the strainer 148 is wrapped around the bottom end of the pump motor 147 where the water enters the pump motor 147. In addition to serving as a filtration of the water before the water enters the pump motor 147 and eventually exits through the spa jet assembly 170, the strainer 148 may also serve to cushion the pump motor 147 if it rests on the floor of the bathtub. The strainer 148 is removable (for example, for cleaning or for replacing).
In one example, an outlet opening 141 (e.g., outlet barb) of the pump unit 140 is connected by the water supply tube 160 (e.g., via a barb connector of standard size) to the spa jet assembly 170 held in the user's hand, which is also connected (e.g., via a smaller connector of standard size) to an air supply tube 150 for air supply. In one example, the diameter of the water supply tube 160 is greater than the diameter of the air supply tube 150. Any combination of standard sized air supply tube and/or water supply tube may be used. And fittings (e.g., adapter fittings, conduit fittings, etc.) may also be used (as needed) with either or both of the air supply tube and/or water supply tube. In one example, the water supply tube 160 and air supply tube 150 are both of a standard size, allowing different models/manufacturers of spa jet assemblies 170 with matching barb-style connectors to be changed out on the jet massage device 100 of the present disclosure.
In one example, a “muffler” may be added on the air supply tube 150 to reduce noise during operation of the jet massage device 100. In one example, an air control valve mounted above the spa jet assembly 170 may be included and is operated by the user to control the amount of air bubbles in the air-water stream exiting from the spa jet assembly 170.
In one aspect, the jet massage device 100 allows the user to hold the small spa jet assembly 170, allowing freedom of movement and positioning of the air-water jet stream. Being capable of being hand-held, the jet massage device 100 may be used for focused massage of any part of the user's body as the user chooses. For example, the user can control the air-water stream by the following:
In one example, the electrical cable 1520 includes a fuse 1526. In one example, the fuse 1526 is housed in a waterproof, automotive type fuse holder that is in-line with the electrical cable 1520. In one example, the electrical cable 1520 includes two conductors 1522 and a control circuit 1524. In one example, the control circuit 1524 is sequentially placed between the two conductors 1522 as shown in
In one example, the water supply tube 1560 is made of flexible material to allow bending and curving. Unless disclosed here, other features of the jet massage device 1500 may be the same or similar as those of the jet massage device 100 illustrated herein and in the previous figures.
In one example, the jet massage device (100 or 1500) includes waterproof light emitting diodes (LEDs), or other type of low-voltage lighting device(s), for example on pump unit or other part of the jet massage device. In one example, the LEDs or low-voltage lighting devices are connected to the same electrical circuits as the pump unit. In one example, the LEDs or low-voltage lighting devices change light intensity representative of the intensity of the water flow output from the pump unit 140. In another example, the power supply and control circuit of the lights are separate from that of the pump unit 140. In one example, LEDs or low-voltage lighting devices are also included one or more of the spa jet assembly and water supply tube.
In one example, the jet massage device (100, 1500) includes one or more DC control circuits units, for example, coupled between a DC power supply and pump cables. In one example, the DC control circuit unit includes different control features, including programmable circuits. The DC control circuit may use standardized electrical connections that are readily found in a consumer supply store. The DC control circuit may offer different control features (pump power pulsing, ramping, etc.) and/or massage effects. In one example, the power supply may be directly connected to the pump cable, thus enabling the pump unit to be powered with no form of control whatsoever.
