Definitions
- the present invention relates to a refrigerator, which is equipped with means for evaporating condensate accumulating in the device.
- the condensate that accumulates in a refrigeration device on an evaporator that cools its interior is drained via a pipeline into an evaporation pan outside the interior of the refrigeration device, in order to evaporate there and thus be released into the ambient air.
- the evaporation tray is usually mounted on a compressor of the refrigeration device so that waste heat generated by the compressor during operation can be introduced into the collected condensed water and thus promote its evaporation.
- the object of the invention is therefore to provide a refrigeration device with which it is possible to eliminate larger amounts of condensate accumulating space-saving and with minimal energy expenditure.
- an atomizer is connected to an existing collecting device for the condensate in the refrigerator, which atomizer is used to release the condensed water into the ambient air in the form of the finest droplets. These droplets extract the thermal energy required for their complete evaporation from the ambient air and therefore do not burden the energy balance of the refrigerator.
- This atomizer is preferably arranged above a collecting tray which is able to collect drops generated by the atomizer, which are too large for immediate evaporation.
- the collecting device is also preferably connected to an evaporation tray heated by a compressor.
- This evaporation shell can expediently be arranged as an intermediate store from which the atomizer is supplied with water. Such an evaporation tray can expediently simultaneously form the above-mentioned collecting tray for drops produced by the atomizer.
- the atomizer comprises an atomizer nozzle and a pump for pushing the condensed water through the atomizer nozzle.
- This can be an electrically driven pump, in particular a pump with a linearly movable piston and a lifting magnet displaceable in a coil for driving the piston.
- the pump can also be driven by opening or closing a door of the refrigerator, in which case a direct mechanical coupling of the pump to the movement of the door for driving the pump can be considered.
- a high-frequency oscillator in particular an ultrasonic oscillator, can be used to atomize the condensed water.
- FIG. 1 shows a schematic section through a refrigeration device according to the invention
- FIG. 2 shows a schematic section through a pump atomizer of the refrigeration device from FIG. 1;
- FIG. 3 shows a detail of a refrigeration device according to the invention with an ultrasound Atomizer.
- the refrigeration device shown schematically in section in FIG. 1 comprises a heat-insulating housing with a body 1 and a door 2 articulated thereon, which enclose an interior 3.
- An evaporator 5 is arranged on the back of the interior 3, which is divided into compartments by a plurality of shelves 4.
- the evaporator 5 is shown here as a plate-shaped body which is inserted between a wall of the insulating container of the body 1 delimiting the interior space 3 and a heat insulation material 6.
- a refrigerant circuit extends from a high-pressure outlet of a compressor 7 via a condenser 8 attached to the outside of the rear of the body 1 and the evaporator 5 to a suction connection of the compressor 7.
- the compressor 7 is in a recess 9 near the floor on the rear of the body 1 below the Evaporator 5 housed.
- An intake 13 of a pump atomizer 14 dips into the evaporation bowl 12.
- the structure of the pump atomizer is explained in more detail below with reference to FIG. 2. He creates a fine mist above the evaporation tray 12 from this sucked-in condensed water, the droplets of which evaporate quickly due to their small size.
- the air humidity generated in the niche 9 is washed away by an air flow which, driven by the condenser 8 into a chimney between the rear wall of the body 1 and an opposite, not shown furniture or building wall, initially by one along the underside of the Body 1 guided intake duct 15, then through the niche 9 and finally through the chimney to the outside.
- FIG. 2 shows an example of a possible construction of the pump atomizer 14.
- the suction nozzle 13 opens into a pump chamber 16, in which a piston 17 can be moved back and forth.
- a check valve is closed, which is shown here as a ball 18, which is held pressed by a leaf spring 19 against a valve seat 20 at the inlet of the pump chamber 16.
- a line 21 extends from the pumping chamber 16 to an atomizing chamber 22, in which entering condensed water is strongly swirled before it emerges through a fine nozzle opening and atomizes there into a mist 23.
- the piston 17 is displaceable with the aid of a magnet 25 which is held movably in a coil 24 to which current can be applied.
- the coil 24 is energized in a suitable direction so that the magnet 25 drives the piston 17 into the pumping chamber 16, to the right in the figure, a high pressure is built up in the pumping chamber 16, which leads to that Water flows through line 21 and is atomized.
- the piston 17 and the magnet 25 are rigidly connected or even formed in one piece.
- the compression spring 26 can be omitted because the magnet 25 is also able to drive the movement of the piston 17 out of the pump chamber 16.
- no counterforce of the compression spring 26 needs to be overcome, and the pressure that can be built up in the pumping chamber 16 is increased with the same design and loading of the coil 24.
- a control circuit can be provided which applies current to the coil 24 after a predetermined period of time in order to drive one or more movement cycles of the magnet 25. According to a further development, this control circuit also detects or controls the operation of the compressor 7 and only actuates the pump after the specified time period has elapsed when the compressor is in operation or has already been running for a certain time to ensure that the atomized water is soon removed from the air flow mentioned above.
- the control circuit can also be coupled to a movement of the door 2 in order to detect this and - instead of after the predetermined period of time - to drive a second given number of movement cycles of the magnet 25 after a given first number of door opening or closing operations ,
- a water level sensor may be provided on the evaporation bowl 12, which provides a signal indicating whether or not the water level in the bowl 12 exceeds a predetermined limit, and the control circuit drives the magnet back and forth for as long 25 on how the detected water level is above the limit.
- the coil 24 and the magnet 25 can be replaced by a lever mechanism which is coupled to a movement of the door 2 and which can extend, for example, through the suction duct 15.
- a user simultaneously drives a movement cycle of the piston 17 each time the door 2 is opened and closed.
- FIG 3 schematically shows a section through an evaporation tray 12 mounted on a compressor 7 according to a second embodiment of the invention.
- annular float 28 On the surface 27 of the water collected in the bowl 12 there is an annular float 28 which holds an ultrasonic generator 29 at a fixed, small distance below the water surface 27.
- the ultrasound generator 29 is of a known type, as used, for. B. is conventionally used in humidifiers. It acts as an atomizer by delivering ultrasonic energy to the water above it, resulting in a mist of fine drops rising from the water surface surrounded by the annular float 28.
- the unit comprising the float 28 and the ultrasound generator 29 is held on a swivel arm 31 connected to a switch 30. If the water level rises above a given limit value, the switch 31 closes and supplies the ultrasound generator 29 with energy until the water level has fallen below the limit value again. As long as the water level is low, only the waste heat from the compressor 7 is used to evaporate the condensed water collected. Only when the water level reaches a critical height is the ultrasound generator 29 switched on in order to support evaporation and to prevent the evaporation tray 12 from overflowing.
- the float 28, the swivel arm 31 and the switch 30 form a water level sensor which - without an ultrasound generator - can also be used as the water level sensor mentioned above in connection with FIG. 2.
