Definitions
- the invention relates to a bottom group of a housing having a tumble dryer with at least one arranged below a heat source and a heat sink of a heat pump of the tumble separator shelf on which the heat source and the heat sink stand up.
- a known tumble dryer in particular a condensation dryer, comprises a heat pump with two heat exchangers, namely a heat-emitting heat source and a heat-receiving heat sink, wherein process air used for drying laundry is heated by the heat source and supplied to the laundry for absorbing moisture therefrom, and the moisture absorbed during the drying of laundry is condensed by means of the heat sink to which the process air laden with the moisture is fed.
- a clothes dryer with heat pump has a much lower energy consumption than a clothes dryer without heat pump. The energy efficiency of a clothes dryer with heat pump increases with the volume of heat exchangers used in the heat pump, ie the volume of the heat source and the heat sink.
- a heat pump often used in a tumble dryer contains a refrigerant which circulates in a self-contained cycle and thereby cyclically evaporates while absorbing heat and is condensed with the release of heat.
- the evaporation of the refrigerant takes place predominantly in the heat sink. This can therefore also be referred to as an evaporator or evaporator. It flows to the refrigerant as a mixture of liquid and gas. As a gas, the refrigerant then passes to a compressor, where it is compressed.
- the compressor is also the drive that drives the refrigerant through its circulation. From the compressor, the compressed refrigerant reaches the heat source, where it is liquefied with the release of heat.
- This heat source is therefore also to be referred to as a condenser or condenser.
- the liquefied refrigerant passes into a relaxation device, in particular a valve, a diaphragm or a capillary, in which its internal pressure is reduced and it already partly turned back into gas. The resulting mixture of liquid and gas returns to the heat sink.
- a corresponding tumble dryer with a bottom group comprising a heat pump is known, for example, from DE 10 2008 044 277 A1.
- a liquid tank is usually arranged on the bottom side, in which condensing water can accumulate on the heat sink of the heat pump.
- the liquid basin is also used to collect the flushing fluid used in this case.
- the heat exchangers of the heat pump are usually arranged above the liquid tank, for which purpose above the liquid tank a separating floor can be arranged, on which the heat exchangers stand up. The space below the heat exchanger or the separating tray is thus limited by the liquid pool.
- the object of the invention is to increase the energy efficiency of a heat pump having a tumble dryer and to specify a corresponding floor group.
- the floor assembly according to the invention of a housing having a tumble dryer with at least one below a heat source and a heat sink of a heat pump of the tumble dryer separating shelf on which the heat source and the heat sink stand up is characterized in that in the separating bottom at least a trough-like, waterproof and in the direction the heat source open formed recess is formed, wherein a bottom of the recess is completely below a maximum diesstechniks Stahl a bottom side disposed below the partition floor liquid tank and the heat source rests on the ground.
- the bottom of the depression is located completely below the maximum liquid filling height of the liquid basin arranged below the bottom on the bottom side.
- the recess is trough-shaped and waterproof, a bottom-side portion of the heat source located in the recess can be positioned lower than is possible with a conventional parting tray which would be located entirely above a maximum liquid level of a liquid pool of the clothes dryer.
- the floor assembly according to the invention can thus be developed for the heat source additional space within the liquid pool.
- a heat source with a height that is greater than a height of a heat source that could be installed in the same tumble dryer without the floor assembly according to the invention can be installed in a tumble dryer. This is accompanied by an increase in the energy efficiency of a laundry dryer equipped with a floor assembly according to the invention.
- the possible size of the heat source depends inter alia on how far the bottom of the depression is located below the maximum liquid filling height of the liquid pool.
- the heat source could, at a high, in particular maximum, liquid level in the liquid tank, come into direct contact with a liquid present in the liquid tank. This would be even more likely in a tumble dryer equipped with a self-cleaning system for cleaning at least one heat exchanger of its heat pump, since such a dryer may produce a greater amount of liquid in the liquid pool at least during a corresponding self-cleaning.
- a corresponding immersion of the heat source in a liquid contained in the liquid pool would be associated with a loss of power of the heat source, since on the one hand, the liquid the heat source and thereby indirectly abküh the process air to be heated by her len and on the other hand, the relative humidity in the vicinity of the heat source would be increased.
- the floor assembly according to the invention or its arrangement on a tumble dryer a corresponding loss of power of the heat source, and thus of the heat pump as a whole, can be effectively avoided.
- a clothes dryer of the aforementioned type is a household appliance, which is set up using condensation drying for drying wet and / or wet laundry.
- the tumble dryer may be formed, for example, as a drum dryer, drying oven, washer-dryer or the like.
- At least one securing means for securing a positioning of the heat source relative to the bottom of the recess is arranged on a side of the bottom of the recess facing the heat source.
- the securing means for example, a positive connection between the separating tray and the heat source can be produced.
- the securing means may be formed as a closed, substantially perpendicular from the bottom of the recess projecting wall.
- several separate securing means may be arranged in the form of projections protruding vertically from the bottom of the recess at the bottom of the recess.
- the bottom of the recess is formed supporting.
- the heat source can be placed on the bottom of the recess and carried by this and held.
- the bottom of the recess or the separating tray is to be provided for this purpose with a suitable dimensional stability.
- reinforcing ribs or the like can be arranged on the separating bottom, in particular on the bottom side.
- the separating tray is disposed below the heat source and the heat sink of the heat pump, wherein at least one open in the direction of the evaporator lowering is formed on the separating bottom, so that a bottom of the lowering completely below the maximum copesstechniks Stahl the bottom side located below the partition floor arranged liquid pool of the clothes dryer.
- the lowering does not have to be formed in a watertight and trough-like manner according to the recess, since physical contact between the heat sink and a liquid contained in the liquid tank or consequent cooling of the evaporator does not adversely affect the cooling performance of the heat sink.
- the relative humidity in the vicinity of the heat sink is already relatively high anyway, so that an increase in the relative humidity in its environment can be virtually ruled out by the presence of the liquid present in the liquid tank.
- the lowering may alternatively be formed trough-like and waterproof according to the depression.
- at least one further securing means for securing a positioning of the heat sink relative to the bottom of the lowering is arranged on a side of a bottom of the depression facing the heat sink.
- a tumble dryer in the form of a drum dryer or a washer dryer because of the vibrations occurring during operation of a drum dryer or washer dryer.
- a proper positioning of the portion of the heat sink relative to the bottom of the reduction can be reliably ensured under such loads, which improves the robustness of a suitably equipped clothes dryer and a Geisseschb- formation within the tumble dryer by juxtaposition of improperly interconnected components prevented.
- the securing means for example, a positive connection between the separating tray and the heat sink can be produced.
- the securing means may be formed as a closed, substantially perpendicular from the bottom of the lowering projecting wall. Alternatively, a plurality of separate securing means in the form of protruding perpendicularly from the bottom of the lowering protrusions may be arranged at the bottom of the lowering.
- the bottom of the sink is designed to be load-bearing.
- the heat sink can be placed on the floor of the lowering and carried and held by this.
- the bottom of the lowering or the separating tray is to be provided for this purpose with a suitable dimensional stability.
- reinforcing ribs or the like can be arranged on the bottom of the lowering, in particular on the bottom side.
- At least one opening is formed at the bottom of the depression. Should it happen during operation of a tumble dryer, that the heat sink temporarily partially immersed in a liquid contained in the liquid tank, this configuration at falling liquid level in the liquid tank, a liquid located on the bottom of the sink drain through the opening again and into the liquid pool reach.
- the opening means may be provided, which allow only a drainage of the liquid, but prevent the liquid from entering the area above the separating bottom. If the opening is made relatively large, can also ambient air between the bottom of the Heat sink and the top of the bottom of the sink pass, whereby these areas can be dried, which for example prevents odor or mold on these components of a tumble dryer.
- the heat source is a condenser and the heat sink is an evaporator for a refrigerant circulating in the heat pump.
- the invention also provides a tumble dryer which comprises the bottom group according to the invention or one of its described embodiments.
- This dryer is connected in accordance with the above mentioned floor covering groups of the invention.
