Definitions

  • the invention relates to a heatable bath or shower tray with means for heating and means for connection to media guides a heater.
  • the invention relates to a method for producing a bath or shower tray.
  • the present invention seeks to propose a heated bath or shower tray, which is easier to produce, has a lower weight and at the same time ensures better heat transfer to the bath water. Moreover, it is an object of the present invention to propose a simple and cost-effective production method for the bath or shower tray according to the invention.
  • the above-described object is achieved in that the bath or shower tray made of aluminum or an aluminum alloy.
  • Aluminum or aluminum alloys have a significantly lower weight and at the same time have much higher coefficients of thermal conductivity than conventional steel bath or shower trays.
  • the necessary strength of the bath or shower trays are also provided by aluminum or aluminum alloys.
  • the bath or shower tray according to the invention thus ensures on the one hand a significantly reduced weight while improving heat transfer to the bath or shower water. Preference is given to using aluminum-magnesium alloys, since these are distinguished by good formability and high strength.
  • the bath or shower tray according to the invention is made of at least one superplastic deformable sheet of aluminum or an aluminum alloy.
  • the superplastic deformation of sheets enables very high degrees of deformation and thus correspondingly great changes in shape to be achieved with only a few work steps.
  • the superplastic deformability is basically no property of the aluminum alloy, but rather the structural adjustment of the aluminum alloy. With suitable microstructure adjustment, almost all aluminum alloys, but in particular high magnesium-rich aluminum alloys, can be deformed superplastically. It is a hot forming, which is carried out at about 0.5 to 0.65 times the melting temperature.
  • the superplastic deformation can be achieved in a simple manner, the high degree of deformation, which are necessary for the production of bath or shower trays, with few process steps.
  • means for heating according to a first embodiment of the invention can be made available by heating channels or pipes applied to the bath or shower tray.
  • heating channels or pipes applied to the bath or shower tray can be used in this way to the medium for heating adapted Schukanäle or pipes, for example KunststoffMapkanäle or pipes, alternatively copper pipes.
  • the bath or shower tray according to the invention can be further improved that another deep-drawn sheet of aluminum or an aluminum alloy is provided, which connected to the back of the bath or shower tray the heating channels or pipes of the means for heating the bath or shower tray forms.
  • the heating channels or tubes are provided in one step at the same time when connecting the two sheets available.
  • the second sheet is connected to the first sheet using a soldering process.
  • the second sheet is equipped with a plated aluminum solder layer.
  • the superplastic deformable first and / or second sheet formed from at least one core layer with a magnesium-free cladding on the one hand can be ensured that an enamel layer can be applied very well to the bath or shower tray.
  • it allows the use of very good superplastic deformable aluminum alloys as a core layer with a very high strength, without reducing the adhesive properties of a later applied enamel layer.
  • cladding layers of an aluminum alloy with a magnesium content of less than 100 ppm are considered to be magnesium-free.
  • the alloy types AA 1xxx, AA 8xxx or alternatively also AA 3xxx with an Mg content of less than 100 ppm are therefore preferably used for the cladding layer.
  • the bath or shower tray is insulated on the back.
  • the bath or shower tray is preferably embedded in an insulating body consisting of a heat-insulating material.
  • the bath or shower tray can also be coated on the back with a heat insulating material.
  • a heat-insulating materials are, for example, polystyrene or other plastics, which a corresponding have poor heat conduction. But there are also other substances with low heat conductivity used. Due to the high heat conduction of the aluminum sheets of the bath or shower tray only small amounts of heat are needed to heat the bath or shower tray with good insulation. In addition, the energy consumption for warming the bath or shower tray can thereby be significantly reduced, so that, for example, a connection of the bath or shower tray in the return of a heating system is conceivable.
  • an enamel layer is preferably provided.
  • the above-mentioned object is procedurally achieved in that at least a first sheet consisting of aluminum or an aluminum alloy is formed by superplastic forming in a bath or shower tray.
  • the superplastic forming allows very high degrees of deformation, so that in a few steps from a sheet metal a bath or shower tray can be formed.
  • a sheet with a superplastic deformable core layer and a magnesium-free cladding layer to use.
  • the core layer of the sheet is preferably rich in magnesium in order to easily achieve a superplastic forming and at the same time by a curing process the highest possible strengths in the formed state.
  • an enamel layer adheres better to nearly magnesium-free aluminum alloys, so that over the magnesium-free cladding layer, which has a magnesium content of less than 100 ppm, a very good adhesion of the enamel layer on the surface of the formed aluminum sheet can be achieved.
  • the means for heating the bath or shower tray can be provided in an economical manner by the fact that a second sheet of aluminum or an aluminum alloy is reshaped and the second sheet is firmly bonded to the back of the bath or shower tray, wherein the back of the bath or shower tray together with the formed second sheet forms the means for heating.
  • the second sheet of aluminum or an aluminum alloy merely needs to be reshaped in such a way that when connecting the second sheet to the first sheet already formed for the bath or shower tray, heating channels or pipes are formed on both sides by both sheets. These can then be connected via the connection means with the media guide a conventional heater.
  • the back of a suitably shaped plastic plate is used, which For example, using an ultrasonic welding is applied to the back of the bath or shower tray.
  • the installation of heating pipes or heating channels on the back of the bath or shower tray is thus eliminated. Due to the good heat conduction properties of aluminum, the connection in the return of a heating device is already sufficient to achieve sufficient heating.
  • the bath or shower tray made from the first metal sheet is materially connected by welding or soldering to the rear-provided, deformed second metal sheet.
  • Welding such as brazing, allows for an economic, material bond between the two formed sheets, so that the cost of producing the heated bath or shower tray can be minimized.
  • Both sheets may consist of, for example, a magnesium-rich core material and a magnesium-poor cladding material.
  • Fig. 1 is first in a sectional view a sheet metal 1 of an embodiment of a bath or shower tray according to the invention to recognize, which consists of a core layer 2, a cladding layer 3 and an enamel layer 4.
  • a core layer 2 a cladding layer 3 and an enamel layer 4.
  • the cladding layer 3 is usually almost free of magnesium, ie it contains less than 100 ppm of magnesium. Magnesium interferes with the coating of aluminum with an enamel layer 4.
  • the magnesium-free plating layer 3 effectively prevents diffusion of magnesium to the surface of the plating layer 3, so that the enamel layer 4 adheres better to the aluminum sheet 1.
  • Fig. 2a now shows an embodiment of a heatable bath 5 according to the invention in a schematic side view, with circulating heating channels 6 are indicated.
  • the bathtub 5 according to the invention also has connection means 7 for connecting heating media of a heating device.
  • the connecting means 7 are usually formed according to the connection means of other heating means, such as radiators, so that the bath or shower tray 5 according to the invention can be easily connected to the water cycle of a heater.
  • Fig. 2b shows an embodiment of a heated shower tray 12 according to the invention in a schematic side view.
  • the heating channels 6 and connecting means 7 are similar to those from the Fig. 2a .
  • the exemplary shower tray 12 off Fig. 2b differs from the exemplary bathtub 5 Fig. 2a essentially by the lower edge height and by the approximately rectangular orientation of the tub bottom and side wall to each other.
  • a heated heating medium for example the hot water of a heater
  • the walls of the bathtub 5 or shower tray 12 are heated and the filled water remains warm for a long time.
  • the circulating run heating channels 6 are in the Fig. 2a, b merely indicated and are formed, for example by connecting the first already converted to the shower tray or bathtub sheet metal with the second sheet 8.
  • Fig. 3a, b is a schematic sectional view of the in the Fig. 2a, b illustrated embodiments is.
  • the sheet 8 has been converted accordingly to form heating channels 6 and connected to the sheet 1 cohesively, for example by welding or soldering.
  • the heating channels 6 are formed, through which a heating medium is performed.
  • the back plate and the use of steel or a correspondingly shaped plastic plate is conceivable.
  • a body 9 is shown made of insulating material in which the bath 5 and the shower tray 12 is embedded in order to minimize heat loss.
  • the bathtub 5 or the shower tray 12 may also be coated with heat insulating material only on the back.
  • first metal sheet 1 is superplasticly deformable, formed from aluminum or an aluminum alloy, it is particularly advantageous to mold structures into the region of the metal sheet 1, which later acts as the bottom of the bath or shower tray 5, 12.
  • tears or lens structures can be incorporated into the floor, which reduce the risk of slipping on the floor and increase the tread resistance.
  • a second embodiment of the invention, heated bath or shower tray is in the Fig. 4a, b shown in a schematic sectional view.
  • the sectional view of the second embodiment of a bathtub according to the invention 10 or shower tray 13 separate heating pipes or channels 11 can be seen, which are applied to the rear of the bath 10 and shower tray 13 formed sheet metal 1. Due to the good heat conduction of aluminum, the bath 10 of the invention or the shower tray 13, the metal sheet 1 of the bath 10 or shower tray 13 is homogeneously heated in this embodiment, so that in the bath 10 or shower tray 13 filled water retains its heat longer.
