The example of filter tank/recess structure

Referring to Fig. 2 to 10B, these accompanying drawings are represented the embodiment that suitable recess/filter tank structure and port are provided with.For example, in Fig. 3, shown water connector 133 is positioned at or near the bottom of recess 129, and air connector 141 is positioned at or near the top of this recess.

Referring to Figure 11 and Figure 12, show another configuration.In these two figure, water connector 133 is near the top of recess 129.This structure is applicable to the peripheral water supply in top distribution system 131, and the prior art patent is disclosed like that as described above.Air connector 141 is near the bottom.In this embodiment, can provide a public air inlet for all devices of band air line or air supply system, setting is positioned at the housing servant quarters and locates near the bottom.Select among the embodiment optional, as shown in Figure 6, be arranged at independently air inlet of housing below for each device all provides.Can also be as shown in figure 12 molded or be inserted in the filter tank 127 head cushion 113, rather than head cushion 113 is molded into (accompanying drawing 6) in the housing 103.In Figure 12, by disconnecting being connected of water end (W.E.) mouth 135 in water connector 133 and the filter tank 127, and the connection of air connector 141 gentle port ones 43, and filter tank 127 removed from recess, thus dismounting filter tank 127.This operation is finished by an action,, catches the place of filter tank near the top that is, and firmly pulling makes jockey/port connect disconnection and makes all latch-up structures open.

Referring to Figure 13, Figure 13 represents the water of recess, another structure configuration of air connector.Water connector 133 is arranged on any appropriate position of recess 129.Though be arranged on position near the bottom at this this connector, any appropriate location that it is set to recess all is fine.With water connector 133 adjacents air connector 141 is being set.Both join gentle distribution and supply system 131,139 supplies by suitable moisture for this.Water and air connector 133,141 are aimed at the gentle port one 35,143 of the water on the filter tank 127, to form the gentle passage of suitable water.

Referring now to Figure 14.Water connector and air connector are set together and have formed overall structure 138.In Figure 14, whole water/air connector 138 is installed on the housing 103 in the recess 127.The connector 138 of this integral body or combination is cut apart by the center air duct 161 that is installed in the annular water supply line 163.This jockey 138 is connected the suitable gentle distribution system 131,139 of water.Filter tank 127 comprises water/gas port one 36, and water/gas port one 36 provides with the suitable of water/air connector 138 and is connected.Connector/port combination can also comprise suitable latch-up structure, to lock this connection or lock connector and port.In this embodiment, provide water gentle to nozzle, simplified installation and removal by a connector system.

As mentioned above, water connector is arranged on any appropriate location of recess.It can adopt any appropriate configuration.When filter tank is not installed, preferably, water connector is not pressurizeed.One embodiment of the present of invention are a kind of like this systems, and it makes bathtub obtain the water supply and makes mounted filter tank pressurized, and the jockey that is positioned at empty recess simultaneously breaks with current and separates.This can realize by a valve is provided for each connector, wherein connector be installed in the recess, below the recess or other place in the bathtub.This water connector can also be combined with automatic valve, and this automatic valve turn-offs this water connector when filter tank is disassembled.In these connectors, adopt so-called quick connection valve to connect, when filter tank water end (W.E.) mouth is pushed on the water connector, open this valve, and when filter tank be disassembled and water connector and water end (W.E.) mouth between the connection disconnection time close this valve.

Referring now to Figure 15,, wherein represents details as the quick connection/kick-off valve of water connector/port assembly.Filter tank 127 has water end (W.E.) mouth 135, and its structure is set to be suitable for the water that clamping goes in recess 129 and connects 133 structures.This port organization is suitable for opening clack valve 164 (being represented by dotted lines out the situation that clack valve is opened among the figure), enters filter tank thereby make water to connect by this connector/port.When the dismounting filter tank, pulling force makes this connector separate with port, thereby this makes clack valve close the outflow of prevention water under the hydraulic pressure effect.

Basically, syndeton is suitable for allowing the filter tank port separate from jockey with reversible manner, and also provides the water of pressurization to connect after filter tank installs between water system and filter tank inside.

Air feed connection at recess can be arranged at any suitable location.For atmosphere or non-pressurised air supply system, because this system always is not in pressurized state, so the demand of sealing and valve connects different with water.For these non-pressurised systems, any system that can set up after filter tank installs from the air inlet of bathtub to the air pipe line of filter tank inside all is suitable.In Fig. 6, the air connector 141 near the top that shows at recess links to each other with air supply system 139.Air supply system comprises gas manifold or the air intake structure 168 that is positioned at housing pillow or top rail (top rail) below.Air inlet can be the shell nozzle that is communicated with atmosphere in fact, takes the form of fill opening or baffle openings (plenum or baffled opening) on housing.Attached arbitrarily filter, aqueous water remover or the like can be installed in the air feed manifold of housing below, perhaps hide to be located in the filter tank.For aesthetic consideration and in order to prevent that epiclast from entering air supply system, the air inlet that is communicated with atmosphere preferably adopts retaining to pull protection arbitrarily.But the opening on top rail that leads to top rail below chamber that is communicated with air connector also is can imagine among the present invention to obtain.In addition, the air distribution system that air is offered each recess air connector adopts single air inlet, also can imagine to obtain.The gas port also should be dismantled from air connector with reversible manner, as previously mentioned.Basically, for non-pressurised system, the arbitrary structures that the recess air connector is aimed at filter tank gas port all can be able to be imagined to obtain.For forced gas supply system 139, system comprises that suitable seal part, air compressor, pressure vessel or the like can be imagined and obtains.

Water connector and air connector, and the gentle port of water end (W.E.) mouth that is complementary can comprise suitable latch-up structure, so as to guarantee water gentle enter filter tank and/or help filter tank is fixed in the recess.For example, this can comprise locking annular ring, spring loaded pin and hole.

The appearance and size of filter tank only needs corresponding consistent a kind of like this degree that arrives with the recess size, that is, the gentle port of water of filter tank can be aimed at or be communicated with to the water of recess and air connector, and form the gentle passage of suitable water.May retain remarkable space between the housing wall at recess place and filter tank outer surface, perhaps alternatively, filter tank also can be arranged to closely cooperate with recess.For outward appearance and comfortable consideration, the filter tank jet tray preferably also should closely cooperate with around the recess, thereby provides suitable continuous surface in the bathtub cavity volume.

Bathtub preferably includes the injection apparatus that has identical recess and port organization more than, so filter tank can freely be exchanged, exchange.Alternatively, different injection apparatus need be installed in the ad-hoc location in the bathtub, will consider these difference during the corresponding different filter tank of design and these injection apparatus.For example, angular position device, side device, reclining apparatus, shank injection apparatus can adopt the filter tank/recess configuration and the standard of separating with the foot injection apparatus.Injection apparatus can also be provided with shower nozzle, or other suitable water filling device that is higher than waterline.

Therefore alternatively, some filter tanks can have the nozzle that does not need air feed, are exactly optional for some injection apparatus air connectors that this filter tank is installed.But preferably all reclining apparatus all have air connector, and therefore the filter tank of nozzle arrangements can be used for all injection apparatus arbitrarily, thereby realizes interchangeability completely.For example, be provided with the filter tank that the recess of G﹠W connector can be used to have only the water end (W.E.) mouth, not need air feed simultaneously.Preferably, recess should be arranged so that realizes interchangeability completely between filter tank, no matter and whether filter tank needs to supply water or air feed.

Can imagine that what obtain is to make that filter tank is interchangeable, and make filter tank can have nozzle arrangement miscellaneous.For example, in order to change the nozzle arrangement in the injection apparatus, can just filter tank be dismantled, another identical recess size with this matches, the filter tank of port compatible gets final product and replace.Unique basic demand of filter tank interchangeability is that filter tank will have suitable dimensions and port organization and setting, thereby can be installed in the recess that meets preassigned.

Filter tank internal structure example

In case set the standard of recess structure, wherein said standard is that then filter tank can be configured to the gentle arbitrary structures that is sent to filter tank jet tray top nozzle respectively from the gentle port of water of water at the structure of water and air connector and setting.

Filter tank can be made with any suitable method by any suitable material.Basically, the requirement to internal structure is to deliver to water from the water end (W.E.) oral instructions nozzle water distribution system of nozzle water inlet.Equally, there is a cover gas to be sent to the nozzle air distribution system of nozzle air inlet from filter tank gas port.Any suitable architecture that meets this requirement all be the present invention can imagine and obtain.

Filter tank design can be adopted the conventional spout of obtaining easily on the market, or at the customized nozzle of special filter tank structure.Nozzle can assemble or be installed on the jet tray of filter tank with any suitable method, and described method for example is used on the filter tank housing method of boring and bonding nozzle, perhaps when making filter tank nozzle directly is molded in method on the jet tray.In the accompanying drawings, shown in nozzle be schematically because should be understood that: the present invention is not limited to any nozzle arrangements, the present invention can use the nozzle of any suitable architecture.
