Definitions
- the invention relates to a dishwasher with a washing container.
- a dishwasher has, as is known, a rinsing process 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".
- a rinsing process 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 heating of the rinsing liquid is usually carried out by means of electric heaters.
- 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. Due to the relatively high temperature of the rinsing liquid in the partial program step "rinsing" usually from 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 heating source e.g. a hot air blower, used in the rinsing tank to heat the humid air mixture during the drying process, so that the air in the washing container can absorb a larger amount of 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.
- the dishwashing machine according to the invention with a rinsing container has an air-conductively connected piping system to the rinsing container, into which at least one heat pipe protrudes with both ends, the heat pipe on the one hand being used for cooling and is used for drying as well as on the other hand for heating conducted air from the washing compartment.
- air is passed from the washing container in the at least one partial program step "drying" in the line system and back into the washing, whereby the above-mentioned advantages in the dishwasher according to the invention are used as intended.
- the purge bin has an outlet with a conduit to one end of the heat pipe, a conduit from one end of the heat pipe to the other end of the heat pipe and an inlet with a conduit from the other end of the heat pipe, with one in the conduit End of the heat pipe, a fan is arranged, which supplies at least a portion of the air in the washing container at least temporarily the conduit system.
- a replacement of polluted air from the environment is completely excluded, thus preventing back soiling of the treated material.
- the fan can be easily controlled, so that the use of the heat pipe can be controlled accurately and easily, for example compared to the dishwashing described in DE 27 16686 A1. machine.
- the fan increases the effect of the heat pipe, since the air to be conveyed is promoted faster.
- the air is cooled by means of the heat pipe.
- the cooling is used with removal of the absorbed heat energy.
- the air 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.
- a heater is arranged in the line between the inlet and the other end of the heat pipe. 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.
- a condenser is arranged in the conduit between the outlet and the one end of the heat pipe or alternatively in the conduit between the one end of the heat pipe and the other end of the heat pipe. If the dehumidification of the air through the heat pipe is not sufficient, the air is additionally passed to a condenser to ensure the drying function, which performs the missing dehumidification.
- Show it 1 shows a dishwasher according to the invention in a schematic representation with a vertically arranged heat pipe, the operation of which runs from top to bottom,
- FIG. 2 shows a dishwasher according to the invention in a schematic representation with a vertically arranged heat pipe, the operation of which runs from bottom to top,
- FIG. 3 shows a dishwasher according to the invention in a schematic representation with a horizontally arranged heat pipe, in which the air circulation runs from top to bottom and
- Fig. 4 shows a dishwasher according to the invention in a schematic representation with a horizontally arranged heat pipe, in which the air circulation runs from bottom to top.
- FIGS. 1 ', 1 ", 1'” show embodiments of the dishwasher 1, 1 ', 1 ", 1'” according to the invention with a washing container 2, 2 ', 2 ", 2'” are arranged in the dish baskets, not shown for the classification of items not shown.
- the same parts are marked with the same reference numerals.
- the dishwashing machine 1, 1 ', 1 ", 1'” has a line system 4, 4 ', 4 ", 4'” which conducts air conductively to the washing container 2, 2 ', 2 ", 2'", into which at least one Heat pipe 10, 10 ', 10 ", 10'” with both ends 11, 11 ', 11 ", 11'", 12, 12 ', 12 “, 12'” protrudes, wherein the heat pipe 10, 10 ', 10 " , 10 '", as will be explained in more detail below, on the one hand for cooling and thereby drying and on the other hand for heating air through from the washing container 2, 2', 2", 2 '"is used.
- the rinsing container 2, 2 ', 2 “, 2'” has an outlet 3, 3 ', 3 ", 3'” which leads to the line system 4, 4 ', 4 ", 4'” with a line 5, 5 ', 5 “, 5'” to one end 11, 11 ', 11 ", 11'” of the heat pipe 10, 10 ', 10 ", 10'", with a line 6, 6 ', 6 ", 6'” from one end 11, 11 ', 11 ", 11'” of the heat pipe 10, 10 ', 10 ", 10”' to the other end 12, 12 ', 12 “, 12'” of the heat pipe 10, 10 ', 10 " , 10 '”and with a conduit 7, 7', 7", 7 '"from the other end 12, 12', 12", 12 '"of the heat pipe 10, 10', 10", 10 '"to an inlet 8, 8 ', 8 ", 8'” of the washing container 2, 2 ', 2 ", 2'", wherein in the line 5, 5 ', 5 "
- This dishwasher 1 shows an embodiment of the dishwasher 1 according to the invention is shown schematically.
- This dishwasher 1 has a vertically arranged heat pipe 10, the operation of which runs from top to bottom.
- Such heat pipes white inside a capillary structure, which allows a non-described filled working fluid, from the "warm side” 12 to the "cold Side 11 of the heat pipe 10. Therefore, the line 5 is to the "cold side” 11 of the heat pipe 10 in the upper part of the washing container.
- FIG. 2 schematically shows a further embodiment of the dishwashing machine 1 'according to the invention.
- This dishwasher 1 ' likewise has a vertically arranged heat pipe 10', although its mode of operation, in contrast to the exemplary embodiment shown in FIG. 1, runs from bottom to top.
- no heat pipe 10 'with capillaries is needed, since the working liquid falls by gravity from the "warm side” 12' to the "cold side” 11 'of the heat pipe.
- FIG. 3 A further embodiment of the dishwasher 1 "according to the invention is shown schematically in Figure 3.
- this dishwashing machine 1 has a horizontally arranged heat pipe 10 " From top to bottom, therefore, the conduit 5 "is to the" cold side "11" of the heat pipe 10 "in the upper region of the washing compartment 2".
