Definitions

• the invention relates to an underwater cleaner, in particular for a swimming pool, with a suction nozzle housing with a suction nozzle communicating with a suction nozzle and a Sauggabe defining suction mouth, from the suction chamber emanates an outlet channel, to which a filter device is connected, with an opening into the suction water jet nozzle, via which water can be fed under pressure into the suction chamber so that, in accordance with the principle of the water jet pump, a vacuum is created in the suction chamber.
• swimming pool vacuum cleaner for cleaning swimming pools.
• Such devices are disclosed, for example, by US 5,317,776 A, US 5,842,243 A, US 6,119,293 A or US 6,473,927 Bl.
• the disadvantage is that these known pool vacuum cleaners are relatively bulky, require a certain lead time and / or are cumbersome to handle.
• the US 5,450,644 A shows a battery-powered underwater cleaner, which sucks water via a pump through a suction nozzle and a filter.
• the designed as a radial pump pump is arranged between the suction nozzle and filter.
• the US 4,962,559 A describes a wireless swimming pool vacuum cleaner, in which sucked through a pump through the suction nozzle and a filter water and fed back to the swimming pool.
• the filter is arranged between the suction nozzle and the pump.
• suction pumps suction, wireless underwater cleaners have the disadvantage of low suction, so that massive impurities such as sand, soil, pebbles can be sucked only insufficient.
• Pool vacuum cleaners with a higher suction capacity are not suitable for cleaning even hard-to-reach areas such as steps or corners of a swimming pool.
• a battery-powered pool vacuum cleaner in which water is sucked together with impurities and conveyed into a filter in accordance with the principle of the water jet pump via a suction nozzle. Since the water jet nozzle opens into the suction chamber at a relatively large distance from the suction nozzle, massier dirt particles can not or only with difficulty be removed.
• the water jet nozzle is supplied by a submersible pump, which removes water at the highest point of the suction chamber via a sieve. This has the disadvantage that when starting the pool vacuum cleaner the submersible pump promotes relatively long air only, because, the suction chamber is previously manually flowed tet. In any case, commissioning is difficult.
• the minimum depth of use is determined by the relatively large distance between the intake opening of the submersible pump and the surface to be cleaned. By sucking the water from the suction chamber there is a risk that particles clog the screen very quickly.
• a suction nozzle for a pool vacuum cleaner is known, is sucked in the polluted water according to the principle of water jet or Venturi pump.
• a water hose of an external water pressure source can be connected to the suction nozzle. Due to the water flowing into the suction chamber via the water jet nozzle, a negative pressure is created in the suction chamber, so that polluted water is sucked in via the suction nozzle.
• the disadvantage is that even with this suction nozzle only relatively light and low-mass soiling can be removed.
• a swimming pool cleaner which has a manifold for pressurized supplied water, from which branches off a number of Fegeschläuchen over which contaminants are fluidized. From the manifold lead further jet nozzles in the designed as Venturi chamber suction chamber of the pool cleaner, the jet nozzles are arranged distributed around the circumference of the suction nozzle. After the water jet principle, water is sucked in from the area of the bottom of the swimming pool and led to a filter. Since the jet nozzles essentially lead away from the sowing level at an angle of about 90 °, no impurities can be torn off the pool floor with them. This function must be taken over by the hoses.
• This pool cleaner is complex, voluminous and relatively unwieldy in the application. In addition, a high water flow rate and thus a pump with high flow rate is needed.
• FR 2 667 099 AI discloses a swimming pool vacuum cleaner, wherein two water jet nozzles open tangentially in a suction chamber and generate a swirl flow.
• the water jet nozzles are directed to the sowing level, wherein the fluid line of the water jet nozzles with the sow level an angle ⁇ 0 ° span.
• the flow rate through the water jet principle is relatively low due to the flow-unfavorable arrangement.
• the dirt is whirled up, so that a back pollution of the swimming pool by stray dirt particles can not be excluded.
• Another disadvantage is that two water jet nozzles are required, whereby a pump with a relatively high flow rate must be provided.
• the object of the invention is to avoid these disadvantages and to increase the cleaning performance for underwater cleaner of the type mentioned in the simplest possible way.
• the underwater cleaner should be as small as possible and handy to allow easy cleaning of steps or corners in a swimming pool.
• this is achieved in that the water jet nozzle in the region of the suction nozzle opens into the suction chamber, wherein preferably the distance between the water jet nozzle and the Saubiee is less than the smallest inner width of the outlet channel, and that a fluid line of the water jet nozzle in the region of the mouth in the Suction chamber with the sowing level an angle> 0, preferably> 0 and ⁇ 45, includes, wherein preferably the distance between the water jet nozzle and the sowing level corresponds to a maximum of two-thirds of the smallest inner width, preferably at most half the smallest inner width of the outlet channel.
• the distance between the water jet nozzle and the suction level is less than half the maximum height of the suction chamber.
• the distance between the water jet nozzle and the sowing level is a maximum of 7 cm, preferably a maximum of 2.5 cm to 3 cm.
• the water jet opens as close as possible to the suction level in the suction chamber. This causes the dirt particles are directly flowed by the water jet and torn away in the direction of the outlet channel, so that even massive dirt particles that could not be removed by the mere suction alone, can be solved from the bottom of the swimming pool and transported into the filter. The removal of impurities thus takes place by a combination of suction and pressure effect of the water jet. It is particularly advantageous if the water jet nozzle opens on a side opposite the outlet channel side into the suction chamber, wherein it is preferably provided that the water jet nozzle is directed into the outlet channel, with particular preferably the fluid line with the axis of the outlet channel an angle smaller than 180 ° , preferably between 150 ° and 170 °.

Due to this relatively low installation position of the suction opening of the underwater cleaner can be used even at low water levels. Since the submersible pump water not directly from the suction chamber, but outside of the suction takes directly from the pool, the commissioning of the underwater cleaner is straightforward, because on the suction side of the submersible pump air-filled spaces are avoided.
