Definitions
- the invention relates to a heater for heating the washing liquid in a dishwasher with a pump which is connected in a liquid-conducting manner to a washing container and is arranged outside the washing container and consists essentially of a motor and an impeller arranged in a pump housing.
- Dishwashers are operated with washing programs in which heated washing liquid is circulated by a pump, the washing liquid acting on the items to be cleaned arranged in a treatment room - a washing container - by means of appropriate devices, usually by means of spray devices, such as rotating spray arms.
- heating means are arranged in dishwashers, which are arranged, for example in DE-OS 35 28 696, on the bottom of the washing container.
- the arrangement of heating means on the bottom of the washing container leads to a reduction in the size of the filling space for items to be cleaned and to calcification of the heating means due to the evaporation of the washing liquid when the heating means is completely dried again.
- the heating means are also arranged in a continuous-flow heater which can be arranged outside the washing compartment. This arrangement requires an additional outlay on liquid lines and reduces the space for the arrangement of units required in a dishwasher.
- the invention is therefore based on the object of providing a powerful heater for heating the washing liquid, which is arranged outside the washing container, without restricting the space for further units of the dishwasher.
- heating means are arranged on the pump housing in heat-conducting contact with the interior of the pump housing.
- the pump with the motor and pump housing is arranged outside the rinsing container, the loading space of the rinsing container is not restricted, since liquid lines which are required anyway are used.
- the heating means are arranged according to the invention on the pump housing of the pump which is required anyway, no further aggregate is required in the space outside the rinsing container, so that there is no restriction of this space for further aggregates. Since all of the rinsing liquid is circulated by the pump, i.e. is repeatedly passed through the pump housing, sufficient heating of the rinsing liquid is reliably ensured and efficient heating is created.
- the invention provides a powerful heater for heating the washing liquid, which is arranged outside the washing container, without restricting the space for further units of the dishwasher.
- the heating means are arranged on the outside of the pump housing according to a preferred embodiment of the invention.
- the heating means are arranged on the outside on the side of the pump housing facing the motor. Due to the arrangement of the heating means in the space between the motor and the pump housing, additional protection of the heating means is not necessary.
- a further improvement in the accessibility of the heating means, for example for repair work but also easier assembly, is achieved according to an advantageous embodiment of the invention in that the heating means are arranged on the outside on the side of the pump housing facing away from the motor.
- the heating means are designed as electrical resistance heating, which can preferably be designed as a tubular heater or alternatively as a thick-film heater.
- the part of the pump housing that carries the heating means is made of stainless steel.
- the part of the pump housing that carries the heating means is equipped with an enameled surface.
- an enameled surface In particular when using thick-film radiators, which are usually applied directly to the surface as a paste-like mass and therefore require an insulating layer for metallic supports, the use of e.g. enameled sheets avoided applying an additional insulating layer.
- the use of non-rustproof materials for the part of the pump housing that carries the heating means is also possible, since the enamelled surface ensures protection of the surface that comes into contact with the flushing liquid, which may have chemical additives.
- a temperature switch is arranged in a particularly advantageous manner, the temperature switch alternatively being 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 rinsing liquid or to control the operation of the heating means.
- the thermal switch is expediently arranged on the pump housing.
- the heating means are according to a preferred embodiment of the invention covered with an insulating layer, thus avoiding energy loss and damage to the motor.
- the insulating layer is expediently covered with a protective plate.
- FIG. 1 shows a schematic representation of a section through a pump of a dishwasher with heating means arranged on the outside on the side of the pump housing facing the motor according to a preferred embodiment of the heating according to the invention
- FIG. 2 shows a schematic representation of a section through a pump of a dishwasher with heating means arranged on the outside on the side of the pump housing facing the motor according to an advantageous embodiment of the heating according to the invention
- FIG. 3 shows a schematic illustration of a section through a pump of a dishwasher with heating means arranged on the outside on the side of the pump housing facing away from the motor according to a further advantageous embodiment of the heating according to the invention
- FIG. 4 shows a schematic representation of a section through a pump of a dishwasher with heating means arranged on the outside on the side of the pump housing facing away from the motor according to a further advantageous embodiment of the heating according to the invention
- Dishwashers are operated with washing programs in which heated washing liquid is circulated by a pump 1, the washing liquid using appropriate devices, usually using spray devices not explained in detail. directions, such as rotating spray arms, arranged in a treatment room - a washing container 2 - arranged, not shown, to be cleaned.
- the pump 1 is arranged outside the washing container 2, which is only shown in sections.
- the pump 1 is connected to the rinsing tank 2 via a suction pipe 3 in a manner not described in a liquid-conducting manner.
- the pump 1 essentially consists of a motor 4 and an impeller 5, the impeller 5 being surrounded by a pump housing 6.
- the pump housing 6 is composed of two parts - 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 a bayonet fitting, not described in more detail, with the interposition of a seal 11 and with the housing of the motor 4, which is not explained in more detail connected.
- the direction of flow of the rinsing liquid is indicated by an arrow 9.
- heating means 10, 10 'on the pump housing 6 are in thermally conductive contact with the interior of the pump housing 6, i.e. arranged with the flushing liquid passed through the interior of the pump housing 6. It is also common to all the exemplary embodiments shown that the heating means 10, 10 'are arranged on the outside of the pump housing 6 and that all the heating means 10, 10' shown are designed as electrical resistance heating, tubular heating elements being designated 10 and thick-film heating elements 10 '.
- a temperature switch 13 in the exemplary embodiments a thermal switch, is arranged on the pump housing 6 for securing the temperature of the heating means 10, 10 ′ and for regulating the temperature of the rinsing liquid or for controlling the operation of the heating means 10, 10 ′.
- a pressure switch is also possible.
- FIG. 1 and 2 show embodiments of the invention in which the heating means 10, 10 ′ are arranged on the outside on the side facing the motor 4 - on the lower part 8 of the pump housing - of the pump housing 6.
