DE102011102584A1 - Device for electronic control of liquid body wash in sanitary area e.g. shower for use by physically disabled people, has water pump that is operated, when motion sensor is switched on, so that cleaning agent is transported to shower head - Google Patents

Abstract

The device comprises plexiglass(RTM: light transparent weather resistant thermoplastic) case, water pump, battery and timer. The water pump is operated for predetermined period, when motion sensor is switched on, so that liquid cleaning agent is transported to shower head.

Description

The device contains a pump (washing water pump), battery and timer. Charging takes place by means of a solar panel with low voltage (12 V).

By light (artificial light or window light), which hits the solar panel, the battery is charged. You do not need an additional power source. The device is easy to fix by screws or hooks on the shower screen. This device consists of a Plexiglas housing and a thickness of 3 mm, thereby shock and water test.

The device is mounted to the shower. Advantage: It will be very helpful especially for people with disabilities, also for appropriate nursing staff. Can also be used in hotels - also outdoors. Solution: By adding the liquid soap at the same time, the device is water-saving and practical. No extra shower bottles in the shower room.

Figure 6 shows the technical drawing functional.

Functionality:

• A

  = Pump

  B

  = Supply pipe for the soap

  C

  = Non-return valve for backflow prevention

  D

  = T-piece to continue soap

  e

  = Hose

  F

  = Input connection to the tap

  G

  Timer for determining how long soap will be in the water cycle

  H

  = Relay (responsible for the motion sensor)

  I

  = Motion sensor

  J

  = Battery for operating the pump

  K

  = Output f. Water connection shower hose

  L

  = Vessel f. d. Soap plexiglass housing 3 mm

From point (F), water flows through a tee (D) to connect the shower hose (K) to the shower head. Only when the motion sensor (I) is switched on, a time switch relay is activated, which switches on the wash water pump (A) for approx. 5 seconds. Time adjustable. The pump withdraws from the container (L), which can be filled with 700 ml liquid soap, the soap and shoots it through the backflow preventer (C) to the tee and on to (K), where it can escape at the shower head which leads to it that soap and water is mixed. The supply pipe (B) leading to the soap container (L) is filled with liquid soap. The battery (J) is charged by the solar panel (low voltage, extra overvoltage protection not necessary). When the battery is empty, the charging time is 30 hours. Charging is generally not necessary in case of light.

Description of an embodiment:

As you enter the shower, run water and touch the motion sensor with your hand to turn on the unit and mix the soap with water (body cleaner exits about 3 seconds after it has been pressed).

When touching the sensor again, repeat the process.

Claims (1)

Device for the electronic control of liquid body cleanser in the sanitary area (shower), characterized in that the device consists of a Plexiglas housing, characterized in that when switching on the motion sensor, the wash water pump starts and thus liquid detergent is transported into the shower head.
