Problems solved by technology

[0003] However, it has been shown that the filter device clogs up relatively quickly during an above-mentioned filter operation, although the water from the pump has been roughly cleaned by a coarse filter on the pump.
As a result, the filter operation must be interrupted more often in order to clean the filter device
Frequent cleaning of the filter unit is also associated with unpleasant things, because the pool filter must be removed from the pool for this purpose

Embodiment Construction

[0015] FIG. 1 shows a schematic side view of a longitudinal section of a pool filter 1 . The pool filter 1 has a housing 3 comprising a housing wall 3.1 in which a water inlet 3.2, a pool outlet 3.3 and a channel outlet 3.4 are formed. During filtering operation a flow path is formed in the housing 3 which extends between the water inlet 3.2 and the basin outlet 3.3. In the flushing operation a flow channel is formed in the housing 3 which extends between the water inlet 3.2 and the channel outlet 3.4.

[0016] The housing 3 has a transverse axis X and a longitudinal axis Y. A direction perpendicular to the longitudinal axis Y and perpendicular to the transverse axis Y is designated Z-direction. The housing 3 has a base 3.5, on which feet 3.6 are formed in order to support the housing 3 on a foundation. The water inlet 3.2 forms the end of the housing 3 away from the bottom along the Z direction. Moreover, the pool outlet 3.3 is formed at a position away from the bottom su...

Abstract

The invention relates to a pool filter comprising a housing, which can be supported on a ground side on the base, a longitudinal axis and a transversal axis, and a water inlet, a channel outlet and a pool outlet which are embodied in the housing wall thereof. A flow path from the water inlet to the pool outlet is embodied in the housing on the filter in the filter system and a filter device is arranged in the flow path. The invention is characterised in that a pre-filtering unit is arranged in the flow path in front of the filter device.

Description

technical field [0001] The invention relates to a pool filter with a pre-filter device, which is provided with a housing. Background technique [0002] Such a pool filter is known from the general prior art. Such a pool filter is conventionally installed on the floor of a pool and is arranged downstream of a pump which pumps the water to be cleaned into the pool filter. A filter device is arranged in the pool filter, which intercepts suspended matter contained in the water to be purified and, in certain cases, carries out a biological purification by means of additional filter aids. The purified water is then discharged back into the pool at a pool outlet. It is likewise known to have such a pool filter with a channel outlet through which water is drained when the pool filter is cleaned in a rinsing operation. [0003] However, it has been found that the filter device clogs relatively quickly during an above-mentioned filter operation, even though the water from the pump ...
