Definitions

  • the invention relates to a combined suction and liquid discharge device with a container for liquid detergent and a pump for pumping the liquid detergent via a riser from the detergent container to a discharge device, with a dirt container for sucked-up dirt and dirt-laden liquid via a suction hose into the dirt container a common cover part for detergent containers and dirt containers, the cover part sealing the dirt container and the detergent container airtight and liquid-tight.
  • CH 575 748 Such a combined suction and liquid discharge device is known, for example, from CH 575 748.
  • CH 575 748 describes a generic device which can be used both as a combined suction and liquid discharge device and as a pure suction device.
  • a liquid-tight dirt container is hung in the detergent container.
  • this container When used as a pure suction device, this container is removed and the entire volume of the detergent container is used as a dirt container. To do this, in a further operation after the Removing the dirt container before putting the cover part back on, the riser can be removed from the cover part, since it otherwise remains in the detergent container now used as a dirt container and can be damaged or contaminated.
  • the object and the aim of the present invention are to find a combined suction and liquid discharge device of the type described in the introduction, in which the removal of the riser from the cover part for using the device as a pure suction device no longer has to be carried out in a separate operation.
  • valve body is provided in the opening in the cover part, which closes the opening when the detergent container is removed from the dirt container, this prevents the supply of false air to the dirt container during pure suction operation.
  • a higher negative pressure can therefore be generated in the dirt container and thus the vacuum can be used to vacuum with the detergent container removed just as well as with a conventional suction device.
  • valve body consists of a flexible membrane which is fixed on one side to the edge of the opening in the dirt container and which has the opening in the cover part when the container for the cleaning liquid is removed has proven to be a particularly inexpensive and reliable design of such a closing valve of the dirt container closes.
  • the riser is rigid in its upper region and lifts the valve body from its seat in the opening in the cover part when the detergent container is inserted into the dirt container. This saves an additional component for opening the valve body when the detergent container is inserted.
  • the riser is detachably attached to the detergent container, this has the advantage that the riser can be removed from the detergent container for cleaning or repair in the event of any damage or wear.
  • the riser is detachably attached to the detergent container with a quick-release fastener.
  • the riser pipe For cleaning and maintenance of the riser pipe, it has proven to be very favorable if it consists of a rigid pipe section in its upper area and a flexible hose in its lower area, the rigid pipe section and the flexible hose being separable from one another.
  • a microswitch is provided which is actuated by an actuating element on the detergent container and which prevents the pump from being switched on when the detergent container is removed.
  • the pump for the liquid cleaning agent has a non-return valve on its suction side, which is opened by a cleaning tappet fastened to the riser pipe with the cover and the detergent container inserted. This is to reduce the risk of the pump running dry immediately and being damaged if it is switched on accidentally with the detergent container removed.
  • the check valve replaces a complex electrical safety circuit that prevents the pump from starting when the detergent container is removed.
  • a particularly compact design for the combined suction and liquid discharge device according to the invention is obtained if the pump for the liquid cleaning agent and the motor suction fan are arranged together on the cover part of the dirt container.
  • Figure 1 shows a combined suction and liquid discharge device with a container 1 for liquid detergent and a pump 2 for pumping the liquid detergent via a riser 3 from the detergent container 1 to a discharge device 4.
  • the detergent container 1 is inserted into a dirt container 5 for sucked-up dirt and contaminated liquid 6.
  • a motor suction fan 7 is used to suck dirt and dirt-laden liquid through a suction hose 8 into the dirt container 5.
  • a common cover part 9 is provided for the detergent container 1 and the dirt container 5.
  • the riser pipe 3 is attached to the detergent container 1 and, when the cover part 9 is in place, passes through an opening 10 in the cover part and, via a coupling part 11, makes a liquid-tight connection to the suction side of the pump 2.
  • the riser on the coupling part is sealed by means of one or two rubber rings 12, 13 which are fastened on the connecting piece of the riser 3.
  • a valve body 12 which consists of a flexible membrane and which closes the opening 10 when the detergent container 1 is removed from the dirt container 5.
  • the riser 3 is rigid in its upper region 14 and, when the detergent container 1 is inserted into the dirt container 5, lifts the valve body 12 from its seat in the opening in the cover part.
  • the riser pipe is fastened to the upper edge of the detergent container 1 with an adjusting lock 15, which consists of a flexible clip.
  • the riser 3 consists of a rigid pipe section in its upper region 14 and a flexible hose in its lower region 15, the rigid pipe section and the flexible hose being separable from one another.
  • the pump 2 for the liquid cleaning agent has a non-return valve 17 on its suction side, which is opened by an actuating tappet 18 attached to the riser pipe with the cover 9 and detergent container 1 inserted.
  • the pump 2 for the liquid cleaning agent and the motor suction fan 7 are arranged together on the cover part 9 of the dirt container 5.
  • the pump 2 is arranged on the blower outlet channel 20, so that no special mounting for the pump 2 is required and less base area for the motor-driven blower 7 and pump 2 on the cover part is required.
  • a microswitch 19 can be provided (shown in dashed lines in FIG. 2), which is actuated by the detergent container via two magnetic connections 20, 21 of the same pole and which interrupts the power supply to the pump when the detergent container is removed.
  • the spring-loaded pressure switch 22 is operated with the detergent container removed by the weight of the magnet 20 via the lever 23, so that it interrupts the power supply to the pump 2.
