Definitions
- the invention relates to a hot water tank according to the preamble of the main claim.
- the insulating jacket consists of plastic foam.
- the insulating jacket is formed in one piece with the outer jacket by an integral foam made of polyurethane, the starting materials required for this being introduced into an optionally cooled mold, into which the prefabricated inner body, optionally pressurized inside, is inserted is.
- the insulating jacket is a dimensionally stable foam body made of polypropylene, the inner wall of which is hardened in a water- and vapor diffusion-tight manner by the action of pressure and temperature and directly forms the inner container wall of the reservoir surrounding the water space. This proposal is already based on efforts to protect the environment by facilitating recycling of the foam body
- recycled natural materials according to the invention reduces the cost of production and takes account of the idea of environmental protection by the fact that the starting material for the insulating jacket is already produced from abundant waste materials by a recycling process.
- wood waste, raw cellulose, flax, hemp, textile waste and preferably waste paper are suitable as natural substances.
- ISOFLOC is a material made from recycled paper that is used to form insulating fillings in cavities in roofs, walls and ceilings.
- the insulating jacket can be manufactured simply by blowing the thermal insulation material, as is known per se, into the cavity between the inner container and the outer jacket.
- a film bag made of recyclable material, preferably polyethylene can advantageously be inserted between the inner container and the outer jacket, into which the thermal insulation material is blown.
- the film bag prevents the thermal insulation material from escaping through recesses in the outer jacket, which are provided for the implementation of functional elements of the device.
- the thermal insulation material is compressed into inherently rigid molded parts, in particular half-shells, which form the insulating jacket. It is thereby achieved that no forces are exerted on the inner container during the production of the insulating jacket and this can therefore be made relatively thin-walled. This also makes it easier to remove and recycle the insulation jacket.
- a substance that reacts appropriately under pressure and temperature may also be added to the starting material.
- FIG. 1 An embodiment of the invention is shown in the drawing and explained in more detail in the following description.
- the single figure shows in perspective the details of the housing of a small electrical storage device, which is designed for wall mounting.
- the device shown has an inner container 10 with a connecting flange 12 for functional elements not shown, such as water inlet, water outlet, tubular heater and thermostat.
- functional elements such as water inlet, water outlet, tubular heater and thermostat.
- two shell-shaped molded parts 14, 16 are provided, which are preferably pressed from shredded, ground waste paper 18 and, as an insulating jacket, enclose the inner container 10 without a gap.
- the insulating jacket formed from the molded parts 14, 16 is surrounded by a housing jacket which is composed of a rear jacket shell 20 and a front jacket shell 22.
- the front casing shell 22 has at the top a wall recess 24 which can be closed by a flap (not shown), through which the functional elements of the device and additional thermal insulation elements isolating the connecting flange 12 can be inserted.
