DE3143724A1 - Electrically heatable lavatory seat - Google Patents

Abstract

In contrast to the conventional lavatory seats which endeavour to reduce a sensation of cold in a passive manner (padding), direct electrical heating is here selected. This can result in substantial savings in the costs of heating the lavatory, or prevent possible symptoms of a cold.

DESCRIPTION: Nuremberg, April 11, 1982

Title:

State of the art: Electrically heated toilet seat

There are padded, wooden toilet seats, which counteract the unpleasant feeling of cold due to their material properties.

Criticism of the state of the technique: The passive methods (upholstery, wooden Toilet seats) can only be used to a limited extent counteract the feeling of cold. The second possibility of indirect heating because of the toilet heating has the serious one Disadvantage that most of the heat through the ventilation goes off.

Task:

The invention is based on the object To improve the efficiency of heating a toilet seat, thereby significantly To save energy and at the same time possible symptoms of colds (hemorrhoid disease) to counteract.

Solution:

The problem was solved by the Heating in the form of an electric heating loop built directly into the toilet seat.

Further design the invention: The heating loop can be used directly during production the toilet seats are poured in during the casting process ^. A second possibility would be the heating loop subsequently in suitable Inserting toilet seats and then using a pour heat-resistant casting compound.

The power supply could be with a separate Low voltage power supply (24 V) or directly through the supply network (220 V). The "24 v solution" would have the decisive advantage, even in the event of an unforeseeable contact completely harmless with the supply voltage to be.

Obtainable benefits:

With a connected load of the heating of It would bring you 24 watts compared to the additional electric toilet heaters offered with a connected load of at least. SOO watts an energy saving of at least 20OO%. The seat temperature can be adjusted to the Body temperature continuously adjusted so that there may be symptoms of a cold could be avoided. Compared to the other indirect heating options can easily seat temperatures of 30 ° C and more can be reached. You wanted to achieve this with the indirect methods, the room would have to be kept at the desired seat temperature 1 This would require considerable additional effort of heating energy and would have additionally result in an uncomfortable room temperature.

The heating loop is placed in the toilet seat in such a way that heat is evenly distributed is achieved. Then the heating loop with the connection power for the power pack with a suitable pouring compound poured into the toilet seat.

The low-voltage power supply essentially consists of the isolating transformer and one fuse each for the primary and secondary side of the transformer.

The heating loop could be dimensioned so that it is suitable for direct connection to the 220 V network would be suitable.

In addition, an automatic temperature control is possible, e.g. in the form of a PTC thermistor integrated into the toilet seat could be.

It would also be possible to use the heating loop as a sensor for a proximity switch with which one could then automatically initiate the water rinse via suitable electronics.

The cumbersome, subsequent installation of the heating loop can be avoided by For example, the complete heating loop is pre-assembled on a heating loop carrier and then at Manufacturing process of the toilet seat pours the same.
