Definitions
- the invention relates to a method for operating a device with at least one partial program step "drying", as e.g. in tumble dryers, dishwashers, dish dryers, shoe dryers, etc. is used.
- the items to be washed can be dried by self-heat drying if the rinsing liquid is heated in a "rinsing" part program step and the hot, rinsed items are automatically dried by the self-heat of the item to be washed during the drying process the partial program step "rinse" heated to a certain temperature and applied to the items to be washed via spraying.
- rinsing Due to the relatively high temperature of the rinsing liquid in the partial program step "rinsing" of usually about 65 ° C to 75 ° C is achieved that a sufficiently large amount of heat is transferred to the items to be washed, so that the water adhering to the items by the heat stored in the items to be washed evaporated.
- a separate heat source e.g. a hot air blower, used to heat the humid air mixture during the drying process so that the air in the rinse tank can absorb more moisture.
- a disadvantage of the heating systems described above according to the prior art described above is that the heating of the rinsing liquid is associated with a high energy requirement and the required heat energy must be regenerated for each heating phase by means of the electrical heating elements.
- the known heating systems have the disadvantage that the heating of the rinsing liquid in the partial program step “rinse" and the operations in the sub-program step “drying" are themselves associated with a high energy demand and the required heat energy is lost after the drying process.
- Object of the present invention is therefore to provide a method by which it is possible to operate devices of the type mentioned as economically as possible to dry the material to be dried efficiently and to keep the associated energy consumption as low as possible.
- the air is conveyed by means of a blower, thus facilitating control of the use of the heat pipe, e.g. compared to the method described in DE 27 16 686 A1.
- the air is cooled by means of the heat pipe.
- the actual function of a heat pipe the cooling with removal of the absorbed heat energy, used according to the inventive method.
- By cooling the air its moisture absorption capacity is lowered and the moisture content of the air precipitates as condensate.
- the air is heated by means of the heat pipe.
- the air is heated by means of a heater. If the heating of the air through the heat pipe is not sufficient, the air is additionally heated with a heater to ensure the drying function. Despite the additional energy consumption for the heating energy savings compared to the above-described prior art is achieved.
- the air is conducted past a condenser. If the dehumidification of the air due to the cooling by the heat pipe is not sufficient, the air is additionally passed to a condenser to ensure the drying function, which performs the missing dehumidification.
- the inventive method for operating a device with at least one partial program step "drying” is performed in the illustrated embodiment in a dishwasher.
- a dishwasher has, as is known, a rinsing method whose program sequence consists of at least one partial program step "pre-rinsing", one sub-program step “cleaning”, at least one sub-program step “intermediate rinsing", one sub-program step "rinsing” and one sub-program step “drying”.
- the invention in the illustrated embodiment in the at least one part program step "drying" air from a treatment room out of this via a line system, projects into the at least one heat pipe with both ends and back into this, while cooling the air cooled and you moisture is removed and then reheated.
- the treatment space of the dishwasher for this purpose-the washing container- is equipped with an outlet in the upper region of the washing container. From this outlet, an air line leads to a blower and from the blower to the "cold side" of the heat pipe.
- a heat pipe or "heat pipe” has the property by means of a contained working fluid heat at high speed and large amount from one side - so-called “cold side” - of the heat pipe to the other side - so-called “warm side” - the heat pipe If, therefore, the moist air introduced is “cold On the “cold side” of the heat pipe, the humid air removes the heat (sensible heat) and absorbs moisture It also dissipates the heat of condensation (latent heat) and transports the heat to the other end of the heat pipe - to the "warm side” of the heat pipe.
- a further air line leads from the "cold side" of the heat pipe to the "warm side” of the heat pipe and from there to an inlet located in the lower region of the washing container.
- the heated air introduced into the rinsing container is now much drier and therefore again has a high absorption capacity for moisture. It rises in the washing up and takes up the residual moisture on the material to be treated - the items to be washed. It will now, as already described above, fed back to the line system.
- the air additionally becomes air to ensure the drying function passed a condenser, which makes the missing dehumidification.
- the condenser may be arranged in the flow direction of the air before or after the "cold side" of the heat pipe, in the described embodiment, it is arranged after the "cold side" of the heat pipe.
- the air is additionally heated with a heater to ensure the drying function.
- the heater is arranged in the described embodiment shortly before the inlet of the treated air in the washing compartment. Despite the additional energy consumption for the heating energy savings compared to the above-described prior art is achieved.
- a method is provided with which it is possible to operate devices of the type mentioned as economically as possible, to efficiently dry the material to be dried and to keep the associated energy consumption as low as possible.
