Definitions
- the invention relates to a heater for heating the washing liquid in a dishwasher with one connected to a rinsing container to conduct liquid, outside the rinsing tank arranged pump, which consists essentially of a motor and an impeller arranged in a pump housing, heating means on Pump housing arranged in thermally conductive contact with the interior of the pump housing are.
- Dishwashers are operated with dishwashing programs in which heated Rinsing liquid is circulated by a pump, the rinsing liquid using appropriate Devices, usually by means of spray devices, such as rotating ones Spray arms to be cleaned arranged in a treatment room - a rinsing container Loaded items to be washed.
- spray devices such as rotating ones Spray arms to be cleaned arranged in a treatment room - a rinsing container Loaded items to be washed.
- Heating agents are arranged in dishwashers to heat the washing liquid, such as in DE-OS 35 28 696 are arranged at the bottom of the washing compartment.
- the Arrangement of heating agents on the bottom of the rinsing container leads to a reduction in the size Filling room for dishes to be cleaned and for calcification of the heating medium due to the evaporation of the rinsing liquid when the complete drying is repeated Heating means.
- the heating means are also arranged in a water heater which is outside the Rinsing container can be arranged. This arrangement requires an additional one Effort on liquid lines and reduces the space for arranging one Dishwasher units required. Furthermore, e.g.
- a heater for cleaning machines is also known become, with a liquid-conducting connected with a wet chamber, outside the wet chamber arranged pump, which consists essentially of a motor and a there is an impeller arranged in a pump housing and in the direction of flow a swirl housing is arranged upstream of the suction side of the pump housing.
- This swirl housing is surrounded by a heating element.
- a pump is also known in which heating elements are arranged in the wall of the pump housing.
- a heater for heating the rinsing liquid is also in a dishwasher with a liquid-conducting connection to a washing container, Pump arranged outside the rinsing tank, which consists essentially of a Motor and an impeller arranged in a pump housing is known become, in the form of tubular heating elements in the interior of the pump housing are arranged.
- the invention is therefore based on the object of a powerful heater for heating to create the rinsing liquid which is arranged outside the rinsing container, without restricting the space for additional units in the dishwasher.
- heating means are arranged on the pump housing of the pump which is required anyway no additional unit is required in the space outside the washing compartment, so that there is no restriction of this space for further aggregates.
- the entire rinsing liquid is circulated by means of the pump, i.e. repeated through that Pump housing, sufficient heating of the rinsing liquid is guaranteed guaranteed and created a powerful heating.
- a powerful Heating created to heat the rinsing liquid outside the Dishwasher is arranged without the space for additional units of the dishwasher limit.
- the outside arrangement of the heating elements continues to ensure better access to the heating means, e.g. for repair work, but also a simpler installation and avoids a reduction in pump performance Disruption of the flow paths of the rinsing liquid pumped.
- the heating means are on the outside arranged on the side of the pump housing facing the motor.
- a further improvement in the accessibility of the heating means, e.g. to repair work but also the easier assembly is according to an advantageous embodiment Invention achieved in that the heating means on the outside facing away from the engine Side of the pump housing are arranged.
- the heating means are advantageously designed as electrical resistance heating, which is preferably designed as a tubular heater or alternatively as a thick-film heater could be.
- Embodiment of the invention achieved in that all of the above Alternatives are the part of the pump housing made of stainless steel that carries the heating means is made.
- the part of the heating element carrying the Pump housing equipped with an enameled surface Especially at Use of thick film radiators, which are usually applied directly as pasty mass the surface can be applied and therefore an insulating layer to metallic supports with the use e.g. enameled sheets the application of an additional Insulated layer avoided. Furthermore, the use of non-rustproof materials possible for the part of the pump housing carrying the heating means, since the enameled Protect the surface of the rinsing liquid with chemical additives surface in contact.
- a temperature switch is arranged in a particularly advantageous manner, the temperature switch alternatively is a pressure switch or preferably a thermal switch.
- a temperature switch serves on the one hand to safeguard the temperature of the heating means and on the other hand to regulate the temperature of the washing liquid or to control the operation of the heating means.
- the thermal switch is expediently arranged on the pump housing.
- the heating means of covered with an insulating layer, thus avoiding energy loss and damage to the motor become.
- the heating means are arranged on the outside on the side facing away from the engine
- the insulating layer is expediently provided with a Protective plate covered.
- Dishwashers are operated with dishwashing programs in which heated Rinsing liquid is circulated by a pump 1, the rinsing liquid using corresponding devices, usually by means of spray devices not explained in detail, like rotating spray arms, in a treatment room - a rinse tank 2 - arranged, not shown, to be cleaned items to be cleaned.
- the pump 1 outside the rinsing tank shown only in sections 2 arranged.
- the pump 1 is with the rinsing tank 2 via an intake port 3 connected in a manner not described in a liquid-conducting manner.
- the pump 1 in consists essentially of a motor 4 and an impeller 5, the impeller 5th is surrounded by a pump housing 6.
- the pump housing 6 consists of two parts assembled - a pump housing cover 7 and a pump housing lower part 8.
- the pump housing cover 7 and the pump housing lower part 8 are in one Bayonet lock not described in detail with the interposition of a Seal 11 and connected to the unspecified housing of the motor 4.
- the direction of flow of the rinsing liquid is indicated by an arrow 9.
