Definitions

  • the invention relates to a washing machine set up for drying with a condenser which consists of a hollow body through which moist process air can flow from bottom to top and which is flushed with tap water for cooling purposes via a switchable valve in the inlet.
  • Such a so-called washer dryer is known from German Offenlegungsschrift 41 04 760.
  • a condenser arranged therein it has proven to be a problem that laundry fluff carried along in the process air during the drying section in particular can settle on the inner wall of the condenser and can dry out after the end of the drying section. This danger is particularly favored by limiting the flow of the cooling water to the smallest possible value in order to save fresh cooling water.
  • the invention has for its object to improve the washing machine described above so that the lint settling in the condenser can be rinsed out again.
  • the amount of water required for the condensation process should be kept as small as possible, whereas a large stream of water is required to rinse out the fluff. Both functions are to be implemented with just one inlet valve.
  • this object is achieved in that the inflow is dimensioned for a water flow which is suitable for flushing the fluff of the hollow body and can be operated intermittently for supplying cooling water.
  • a lint rinsing section can be inserted at suitable times during the washing and / or drying process, for which only a suitably long switch-on phase of the feed valve is required.
  • the invention is further developed in that the inlet is aimed at a baffle plate which distributes the rinsing or cooling water in a bell shape on all sides.
  • a uniform flushing of the inner walls of the hollow condenser body can be achieved, so that during the lint rinsing section, the strong flow of the cooling water reaches all surface sections of the condenser on which lint may have settled.
  • the bell-shaped distribution causes a largely intensive contact of the cooling water with the process air flow, so that the lint entrained by the process air does not reach the blower.
  • a further improvement of the washing machine set up according to the invention can be achieved in that projections projecting into the process air flow are arranged in the lower region of the hollow body and lead cooling water flowing down the walls into the air flow. As a result, large portions of the cooling water are directed directly into the air flow, which comes into more intensive contact with the cooling water. This measure increases the chance of being able to wash out almost all of the fluff carried in the process air stream. It also has a positive effect on the condensation effect.
  • a storage space for the cooling water is arranged in the upper region of the hollow body in the outflow region of the inlet, said storage space being provided with outflow openings which allow the delayed outflow of the cooling water.
  • the storage space arrangement is advantageously made such that its drainage openings are directed into the process air stream. As a result, the intimate contact between the process air stream and the cooling water can be intensified.
  • the hollow condenser body 1 is shaped in accordance with the free spaces remaining in the washing machine and the flow of moist process air flows from the supply air opening 2 arranged at the bottom to the fan connection opening 3 arranged at the top, essentially from bottom to top. This is indicated by the large, hollow arrows.
  • the supply air opening 2 arranged at the bottom is connected in a manner not shown to a tub of the washing machine and also serves as a drain opening for rinsing or cooling water supplied from above and used as such in the hollow body. It is pumped out of the tub in the usual way by a tub pump.
  • the inlet 4 contains a solenoid valve, not shown, and opens onto a baffle plate 5, which distributes the incoming water in a bell shape in the cavity of the condenser. It flows down the inner walls of the hollow body 1 to the inlet and outlet openings 2 and is partially caught by a protrusion protruding into the process air stream.
  • the projection consists of a distributor plate 6 which contains flow openings 7 for the process air. As a result, the cooling water is additionally brought into intensive contact with the process air flow. On the way up, the process air can touch several such projections in a manner not shown here, which force the process air into a meandering path, for example.
  • the cooling water is fed intermittently through the inlet 4. So that the interior of the condenser does not dry out during the feed pauses, as a result of which neither condensation nor lint washing would take place, a storage space 8 is arranged in the upper part in the inflow area of the water supply 4, the baffle wall 9 having drain openings 10.
  • the size of the drainage openings is such that they allow the delayed drainage of the pent-up cooling water at a time which corresponds approximately to the pause in the water supply.
  • the drain openings 10 can be arranged as in the example shown on the sides of the baffle 9 or only on the lower side or in the form of holes.
  • the storage space 8 can, in contrast to the case shown here, be arranged in a ring or U-shape around the cross section of the hollow body and direct its drainage openings into the process air flow from three or four sides. Decisive for the design of the hollow body and the storage space are essentially the local conditions in a washing machine in which this capacitor is to be arranged.
  • the fresh water inlet with its valve, not shown here, is designed for a large water flow rate for flushing out the fluff. Since only a small amount of water flow is required for condensing, the valve for the condensation process can be switched on in cycles.
  • the baffle plate 5 under the water inlet forces part of the fresh water to run down the walls. It also rinses the walls free of fluff during the condensation process. Due to the intensive swirling of part of the cooling water at the projections 6, fluff is washed out of the process air particularly effectively and the condensation effect is improved. In the intervals between the water supply, the water supply in the Storage space 8, the washing of the inner walls of the hollow body 1 and the feeding of the projections 6 for the purpose of swirling the cooling water.
  • the hollow body of the condenser is generally designed in such a way that the water runs at least partially down all walls from the highest point via a baffle plate.
  • the water accumulating during the lint rinsing process and flowing out through the supply air opening 2 into the tub of the washing machine is expediently pumped out by the drain pump so that no lint can get to the laundry. These fluff are then removed at the same time as the water to be pumped out.
  • condenser flushings are advantageously carried out when there is a low water level in the tub which does not reach the supply air opening 2 of the condenser.
  • the blower and the pump can be run while the fresh water is being supplied intermittently.
  • the upper part of the hollow condenser body is freed from fluff by directly washing the walls and the vertical part of the hollow body by swirling the water. With regular automatic use during the washing process, a small amount of water is sufficient to flush the fluff.
  • the measures according to the invention only require an inlet valve and a hose to the condenser inlet 4. Also, no further components are required for a second valve, since the water flow rates can be controlled by switching the valve on for different lengths or in cycles.
