DE2951318A1 - Hand held multi purpose bath spray - has water current deflectable through central head or surrounding elastic spray - Google Patents

Abstract

Time is saved in bathing, and overall hygiene improved by simple and inexpensive means, by use of a hand-held spray, serving a number of functions. The flow of water is deflectable in the handle tube. In each case, following switching-on of a deflecting tap, it is able to emerge through a centrally sited spray head or through an elastic shower spray mounted in a ring shape round this. A cartridge chamber outflow may incorporate a throttling disc, to generate fall in pressure towards a soaped water duct. This permits even soaping over the whole body, with foam generated in the spray head, and easy rinsing, plus massage.

Description

Sanitary hand shower with multiple functions

Showering with soap is becoming more and more popular as part of daily body care in the separate shower stand or in the bathtub, because here with one tolerable expenditure of time and material has a high effect in terms of cleanliness and health maintenance is achieved. However, there are still defects in this process, in particular the that lathering the body by hand by rubbing it with a bar of soap or with liquid soap. Access to all parts of the body is included not possible without special aids. To achieve maximum effectiveness should however, the soap can be distributed evenly over the entire surface of the skin and leave it for a certain period of time.

It is also not beneficial to Rinsing and rinsing process with an insufficiently controlled shower jet Having to handle, especially since many parts of the body are not at all with the standing model can be coated.

The subject of the invention is a hand shower with multiple functions, which in a known manner to the mixer tap of a bathtub or to a shower stand is connected and enables the following functional levels: 1. Evenly across Pleasant lathering distributed over the entire surface of the body, with the lather generated in the shower head itself and the superfluous splashing of water jets is avoided.

2. Rinsing the body surface with a slightly expanded water jet, however, there is still a lot of unnecessary splashing of water jets around is contained.

3. Normal showering with a stronger water jet, using the shower head can be hand-held or wall-mounted.

4. Additional intensive skin surface massage with water pressure jets and massage nubs.

5. Increased stimulation of the skin blood flow through optional use of medicinal soaps.

The problem is solved in the application that in the handle tube a hand shower is provided with a switchover tap through which the water flow, which was previously set to the desired shower temperature, from a shower process can be switched to a soaping process. Washed around in a second channel then a throttled amount of water a soap cartridge and is the one produced in the process Lye stream through a chamber system to form soap foam and through a second, concentrically arranged around the main shower ring-shaped elastic shower squeezed out. The ring-shaped elastic shower head is still fluffy with an easily interchangeable one hairy fleece coated and both cause together that different on a large area Body shapes can be painted evenly and sensitively.

The soap cartridge is intended for one-time soaping and after they have been consumed, the body can remove the soap residue with the same stream of water to be freed. There is also an increase in the water flow by switching the centric main shower can also be partially started up. In the end full shower operation can be set by further actuation of the switchover tap, which can be done in a known manner close to the body or from a wall bracket.

Finally, the double shower head can be used against a known per se Massage head can be exchanged, e.g. with High pressure jets and massage nubs causes an increased blood flow demand, especially when A medical soap cartridge was used in the previous lathering process.

The formation of the soap cartridges and the soap cartridge chamber are associated with a number of features, which are also the subject of the application are: 6. Already the cylindrical overall shape is dimensioned so that in a fixed Period and only by surface detachment the amount of soap in a one-off Body soap is used up.

7. The soap mass is made in such a way that it does not dissolve prematurely and the openings for the lye and soap foam duct clogged.

8. By increasing the surface area within a cylindrical basic shape is the period of time for the soap removal that is required for the body surface soaping Period adjusted.

9. It is intended to add various fragrances to the soap base to be attached and is thus made possible by changing the soap cartridges as required, to make the use of the device more attractive.

lo. The bottom of the cartridge chamber on the outlet side is designed as a throttle disc designed with fine bores to create a pressure gradient to the subsequent foaming channel to produce, which facilitates the foaming process.

11. The walls of the cartridge chamber can be equipped with water channels be provided to ensure that the soap cartridge is flushed evenly.

12. The water guiding channels in the cartridge chamber wall and the throttle disc can optionally also be manufactured in one piece and easily replaceable as an insert be.

13. Instead of the soap cartridges, liquid soap containers can also be used with the same dimensions as the soap cartridges.

14. The liquid soap containers can be used in this way be hooked so that their spout exits through the throttle disc and the liquid soap out of its container through the build-up of water pressure in front of the throttle disc is squeezed.

15. The liquid soap containers can also be placed outside the cartridge chamber can already be used in a housing, which has the functions of a throttle disc, Water channels and plugs take over.

Both together can be inserted or removed from the cartridge chamber will.

The complete device works in the same way as the well-known hand showers to the mixer tap above a bathtub or directly to a shower stand connected and equipped with conventional hitching devices for storage.

When connected to bathtubs, the advantage is inevitably that the water temperature can be set without the shower running through. When connected At shower stands, the water temperature can usually only be felt at the shower outlet. This circumstance can possibly be avoided by the connection hose still a test tap with drainage is connected upstream, which is only activated after the desired The water temperature can be switched to the shower inlet.

When switching to the soaping process, through occurs in the supply line Throttling of the amount of water flowing through a pressure build-up, which under certain circumstances a Backflow of soap solution into the drinking water pipe can result in what is existing contravenes official approval regulations. It is therefore still suggested that the already described test tap to be attached to the mixer tap as a pressure relief valve to form part of the water flow D in the tub drains.

The presence of such a pressure relief valve is also required if a gas water heater is used for hot water preparation, which is used with the greatly reduced water flow rate by itself no longer respond would.

Those to be developed specifically for use in the apparatus of the application Soap cartridges or liquid soap containers should already be colored by the fabric or the color of the envelope can be distinguished by fragrance notes.

They are lined up on plastic sheets for sale and shipping and attached so that it can be easily picked up, rolled up, an attractive sales package and can be unrolled and hung on the wall hook in the bathroom.

The sales packs can contain soap cartridges or liquid soap containers with only one scent note, as well as with mixed sets, so-called family packs, of which there are again different compositions can give.

Finally, it is suggested to use both soap cartridges as well To supplement liquid soap containers with medicinal bath products, especially when used in conjunction with the additional massager, a high level of Provide health promotion. You can use the sales packs in a certain percentage attached.
