Flushing device for rinsing and washing urine bottles, receptacles and other containers containing coarse substances -Sleaning device for the storage and handling of urine bottles, sticks and andra cartons

The invention relates to a flushing device for rinsing and washing urine bottles, vessels and other containers containing coarse substances, comprising a closed water tank connected to the water supply network, a water pump for supplying water from the water tank through a pipe to the wash space by means of nozzles.

In order to recirculate the water, the water-lock-like bend of the drain pipe is always open and at least partially made of a perforated material, preferably a sieve plate, inside the closed container completely surrounding the bend, and a pipe leading to the water tank is provided.

Such a device is known from DE-A-24 60 065, according to which the water used for rinsing is refueled in a separate rinsing tank at the top of the machine, from where it is lowered by its own weight onto the rinsing containers in the washing chamber. The rinsable waste is removed from the water trap with the water flow. At the same time, the choke made at the beginning of the first bend of the water trap ensures that the water trap is sufficiently emptied. The pump, which is directly connected to the water trap of the circulating water system, receives the necessary water by means of a separate solenoid valve connected directly to the washing space in the same way as in a washing machine. When the water trap is full, the circulating water system starts operating while the pump is already running.

The disadvantage of said device is that a separate flushing tank must be arranged at the top of the machine, in addition to which the flushing pressure cannot be adjusted to the desired size. In addition, the amount of water used for recycling depends on the washing space and water trap.

The object of the invention is to eliminate the above-mentioned drawbacks and to develop a coarse waste flushing device in which it is possible to carry out a circulating water wash by means of a pump with the following requirements: 1. The bottom of the washroom must always be open to the drain without moving parts.

2. The circulating water function is started by the water in the pump and the flushing tank, independent of the water level in the water trap of the scrubbing room.

This can be realized with the device according to the invention in such a way that the upper part of the water tank has a shut-off valve that seals the water tank airtight.

In the following, the invention will be explained in detail with reference to the accompanying drawing, in which the figure shows a device according to the invention schematically.

The structure and mode of operation of the device according to the invention are as follows.

The desired amount, e.g. 8 liters of water is led from the water supply network 1 to a water tank 2, from which water is pumped by a pump 3 69751 3 through a pipe 4 to the washing space 5 by means of nozzles 12 placed there.

During the first rinsing step, the water coming from the nozzles 12 at a suitable pressure, e.g. about 1 kp / cm2 and a flow rate of 130 l / min, flushes faeces, blood, papers and other waste from the containers to be cleaned, e.g. The rinsing step can then be repeated if necessary.

After the solids have been discharged into the sewer after the rinsing step or steps, water, e.g. about 5 liters, is supplied from the water supply network 1 to the water tank 2, after which the valve 11 of the air pipe leading from the top of the water tank 2 to the washing room 5 is closed. When the pump 3 is started, water, to which detergent can be added if necessary by means of devices not shown, flows through the pipe 4 to the washing space 5. The pressure in the water tank 2 decreases, whereby the liquid coming from the washing space 5 through the screen 8 is absorbed from which it is recycled at a flow rate of e.g. 100 1 / min.

Finally, the system with its vessels can be disinfected by means of steam generating devices 13 connected to the water tank 2.
