- Siphons in a household appliance wherein the siphon is in a liquid-filled state.
- FIG. 1 shows a schematic representation of an ozone circuit 103 in a domestic appliance 100.
- the ozone circuit 103 is integrated into an air circuit in which a fan 106 draws in air, enriches it with ozone and mist via an ozone generator 101 and a fog generator 123, and enriches the air into a tub 120 of the household appliance 100.
- the mist generator comprises a tank 1 1 1 which is filled with a liquid 1 13. If necessary, liquid can be refilled into the tank 11 of the mist generator 123 with a tank filling valve 15 arranged on the mist generator 123.
- the refilling of liquid in the tank 1 1 1 is in the normal operation of the mist generator 123 continuously necessary, since by the generation of mist continuously liquid 1 13 from the tank 1 1 1 is introduced into the ozone circuit 103.
- the mist generation usually takes place by means of a piezoelectric oscillator, which generates the mist by oscillating at a certain frequency in the liquid 1 13.
- the fog generator 123 has a sensor for an upper level 1 17, which preferably cooperates with the tank filling valve 15 1.
- the tank contents can always be kept at a defined level.
- the tank emptying valve 1 19 cooperates with a sensor for a lower level 121, which allows precise control of the tank emptying valve 1 19.
- the enriched with ozone and mist air in the tub 120 and the work space is brought into contact with the treated.
- the air then flows out of the tub 120, wherein in addition a filter 105 is installed in the circuit 103.
- this filter 105 consists of an activated carbon filter, which frees the air from excess ozone.
- the filter 105 is T-shaped and thus provides a ventilation port 107 of the household appliance via a third outlet. Since the filter 105 is in the circuit 103, it also decomposes 100 ozone during the ozone production phase of the household appliance.
- the switching siphon 207 comprises an opening 109 which is connected via a hydraulic connection 209 to the tank 1 1 1 of the mist generator 123. Via the hydraulic connection 209, the switching siphon 207 can be filled with liquid 1 13 from the tank 1 1 1 or emptied.
- the switching siphon 207 and the tank 1 1 1 are arranged so that their respective liquid levels are at the same height.
- the liquid level in the switching siphon 207 simultaneously with the liquid level in the tank 1 1 1 with existing means such as tank filling valve 1 15, tank emptying valve 1 19, sensor for the upper level 1 17 and sensor for the lower level 121, controlled and controlled .
- the switching of the siphon 207 between closed and open corresponds directly to the liquid level in the tank 1 1 1 of the mist generator 123.
- the switching siphon 207 is in a liquid-filled state.
- the bypass or switching siphon 207 is impermeable to air and forces the flow of air or ozone through the filter 105 to flow. The filter 105 is thus actually turned on.
- FIG. 3 shows a schematic representation of an ozone circuit 103 in the domestic appliance 100 with a switching siphon 207 in a bypass, the tank 11 of the fog generator 123 and the switching siphon 207 being in a state emptied of liquid.
- the bypass or the siphon 207 is thus in an air-permeable state and allows the air and the ozone stream to bypass the filter 105 and to flow through the bypass.
- This state is suitable, for example, in an operating mode of the household appliance, in which the ozone content in the circuit is to be increased.
- the flow resistance of the filter 105 may be additionally increased and, for example, 20 times as high as the resistance of the open bypass.
- Fig. 4 shows a schematic representation of an embodiment of an ozone circuit in a household appliance 100 wherein the switching siphon 207 is integrated into the tank 1 1 1 of a mist generator 123 and wherein the switching siphon 207 and the tank 1 1 1 in a filled with liquid 1 13 state are located.
- the ozone generator 101 and the T-shaped filter 105 are arranged in parallel with the ozone generator 101 is directly upstream of the switching siphon 207. Now, when air is sucked in by the fan 106 and brought into the circuit 103, so first part of the air is enriched with ozone.
- Fig. 5 shows a schematic representation of an embodiment of an ozone circuit in a household appliance 100 wherein the switching siphon 207 is integrated into the tank 1 1 1 of a mist generator 123 and wherein the switching siphon 207 and the tank 1 1 1 are in a deflated state of liquid.
- the switching siphon 207 is integrated into the tank 1 1 1 of a mist generator 123 and wherein the switching siphon 207 and the tank 1 1 1 are in a deflated state of liquid.
- FIG. 6A shows a schematic representation of an embodiment of a filter 105 in a domestic appliance 100, wherein the filter 105 is integrated in a hydraulically switchable siphon 207 and wherein the siphon 207 is in a liquid-filled state.
- FIG. 6B shows a schematic representation of one embodiment of a filter 105 in a household appliance 100, wherein the filter 105 is integrated into a hydraulically switchable siphon 207 and wherein the siphon 207 is in a state deflated by liquid.
- the siphon 207 is in an air-permeable state. As a consequence, the air does not flow through the filter 105, because the flow resistance through the air-permeable siphon 207 is considerably lower. The filter 105 is thus virtually switched off.
- FIG. 7A shows a schematic representation of one embodiment of a multi-stage siphon 207 in a household appliance 100 with the siphon 207 in a liquid-depleted condition.
- a free breathing tube 701 with a ventilation opening 107 opens into a switching siphon 207 until just above the siphon bottom surface.
- the respiratory tube 701 itself is designed as a filter 105, wherein the filtering effect is effected by radial passage through the filter wall of the respiratory tube 701.
- the switching siphon 207 has an integrated bypass flow path on which allows it flowing air from the circuit 103 to flow around the breathing tube 701 side and exit from the siphon 207.
- the switching siphon has an opening 109, which allows filling and emptying of the switching siphon 207 with liquid.
- the ventilation opening 107 of the household appliance 100 and the diversion around the filter 105 are completely opened.
- a mechanical ventilation through the ventilation channel outside an ozone operation can take place.
- the filter 105 is in fact turned off.
- FIG. 7B shows a schematic representation of an embodiment of a multi-stage siphon 207 in a household appliance 100, wherein the siphon 207 is in a middle filling state.
- the mouth of the breathing tube 701 is here in the liquid.
- the integrated bypass is open.
- a mechanical ventilation can take place via the filter 105, wherein the air circulation takes place via the bypass without filtering action.
- an ozone-building mode of the home appliance 100 may be performed.
- FIG. 7C shows a schematic representation of an embodiment of a multi-stage siphon 207 in a domestic appliance 100, wherein the siphon 207 is in a liquid-filled state.
- the siphon is completely filled with the liquid here.
- both the ventilation opening 107 and the internal bypass are closed.
- the respiratory flow of the domestic appliance 100 and the ozone stream or the ozone circuit 103 take place exclusively via the filter 105.
- an ozone depletion mode of the household appliance 100 can take place.
- the filter 105 is actually turned on.
