Definitions

• the present invention is for method and means at outlets for polluted air, primarily outlet air from vacuum cleaners
• the outlet air from a vacuum cleaner there is a great number of very small particles which are not caught by the filters of the vacuum cleaner In homes having a central vacuum cleaner these particles are blown out outside the home, but when using ordinary vacuum cleaners they are blown out in the home In some cases the outlet air may also contain very small liquid droplets, j which below are included in the term particles
• blow out is in the form of dry dust without any measures for binding of the dust, why persons who are near the outblow position immediately are exposed to the harmful dust
• all kinds of blow out devices require some maintenance, primarily exchange of filters and cleaning and exchange or emptying of collecting container
• the object of the present invention to avoid blowing out dust into rooms or otherwise in a way that causes human contact with the dust without introducing other disadvantages It is a further object to obtain a binding of the dust It is also an objective of the invention that all dust that has been sucked up immediately shall be discharged without being collected in a filter or container
• the invention shall also be applicable for all kinds of installations from those having a single outlet to larger installations with a central vacuum cleaner and several connections in various rooms and spaces
• the blowing out of air is from the vacuum cleaner to the sewage system where connection of the outgoing air is between two water traps
• the invention thus is for the method of discharging the air from the vacuum cleaner and the "double" water trap
• the invention also is for a water trap for use with the method
• the water trap which is upstream of the vacuum cleaner, and to which water is regularly supplied from a wash basin or the like, has a higher water column than the water trap downstream of the vacuum cleaner in order to prevent the air from the vacuum cleaner from blowing out in the wrong direction
• FIG 1 shows the device at rest
• FIG. 1 shows the device in operation
• Figure 3 shows an alternative way of arranging the water traps
• Figure 4 schematically shows the components which cooperate in a system with a device according to the invention
• the device according to the invention comprises a first water trap 4 and a second water trap 5 Water is supplied to the first water trap through an inlet tube 1 which is connected to a wash basin 10, a dish washing desk or a similar device which uses water frequently, preferably a least daily
• the first water trap 4 is connected to the second water trap 5 by means of a short tube end as shown in figures 1 and 2, or through a somewhat longer vertical tube as shown in figure 3 or in any other suitable way
• a side tube 2, 16 is connected between the water traps and at its other end it has means 14 for air-tight connection os a hose 12 or other means through which the outflowing air from the vacuum cleaner 11 is supplied Preferably this connection also has a lid 15 for air-tight closure when the device not is in use
• An outlet tube 3 extends itself from the second water trap 5 and is at its other end connected to a soil pipe 13 which is vented in the usual way
• the two water traps are different so that the height H of the water head of the first water trap 4 is higher than
• the two water traps may be positioned at a distance from each other as shown in figure 4 och adjacent each other, possibly joined together as one unit as shown in figures 1-3
• a further tube 16 for air or one may make several connecting points at each such tube 2, 16 Thereby that a wash basin or another often used water consuming unit is connected to the first water trap water is refilled within a short time after that blowing of air has been interrupted why the risk that the second water trap 9 shall remain with so little water that it is not sealed is very small
