Description

CtS Mt M fff

The innovation concerns one that works at low temperature and with low consumption in a closed circuit Laundry washing and drying machine operating in an open circuit working machine is transformable.

There are laundry washing and drying machines known which, in addition to the usual centrifugal means, generate additional means a stream of hot air to dry the laundry.

Such machines can be in a closed circuit, with internal air circulation, as well as in an open circuit Work cycle, with the air '. sucked in from the outside and is expelled to the outside again after use.

These machines are very bulky because, in addition to the usual washing machine components, they also have an additional, built-in electric fan, steam condensation and heating means for drying air with high energy consumption are.

The innovation is primarily based on the task of applying the structure of a conventional washing machine to also one

I create laundry drying machine.

Another task is the easy and inexpensive implementation this transformation.

The innovation is also based on the task of one of to create a washing and drying machine that can be transformed into a closed loop into an open loop and vice versa.

These and other tasks according to the innovation are carried out by a

Laundry washing and drying machine solved, which has a housing, to contain and carry a drum unit with motor, at least one line and a pump for draining the water, a channel for supplying the drum with heating means sucked in by a motor fan and by corresponding heating means has heated air and a channel for the exit of the moist air and is characterized in that a capacitor on the outside of the housing of this machine is arranged, which is in the area of the suction side of the motor fan and the end of the outlet duct for the moist air is connected, wherein the capacitor is removable and a line is provided, which extends from the capacitor to extending to the at least one water drainage line.

The features and advantages of the innovation are shown below with reference to one of the accompanying schematic drawings illustrated, non-limiting exemplary embodiment described in more detail. Show it:

Fig. 1 is a perspective view in partial section of the new

appropriate machine and
FIG. 2 also shows a perspective view of an enlarged detail of the capacitor of the machine according to FIG.

In the drawings, a washing and drying machine according to the control is designated as a whole by 10, which essentially comprises a housing 11 in which a drum unit 12 with the corresponding motor 13 is arranged. One hole 12 leads the runoff water via a first line 15 to a filter 16 and to a pump 17 for final discharge into a drain line 18.

directly from the bottom of the drum unit 12 goes outside

the one channel 19 for the inlet and outlet of the moisture-saturated air, the one designated as a whole with 20 Condenser unit leads, which is arranged in the area of the upper part of the housing 11 of the washing and drying machine 1st.

The condenser unit 20 consists of a prismatic container 21 (Fig. 2) tapered shape, which extends from a
Area 22 for receiving the channel 19 expands to an opposite area 23, where a bore 24 is formed, in which the suction side of a motor fan 25 is located.

The container 21 is for example through a screen 26 in
two areas 22, 23 are separated and in the receiving area 22 has an element 27 for sprinkling cold water taken from the water supply network via a line 28 with a control valve 29. At the bottom of the container 21, a line 30 for discharging the condensed water and the cold water to the filter 16 and to the pump 17 is connected.

The motor fan 25 then sucks the air out of the condenser 20 in a known manner, guides it through a heating means 31, E.g. a group of resistors to heat them up again and from here back into the drum unit 12 via a To lead line 32, creating a closed air circuit.

In the case of a machine in accordance with the innovation, the mode of operation is extremely easy.

After the normal washing process, the laundry should now be dried.

ί

For this purpose throw over snap fasteners (not shown) the circuit of the drying unit switched on. The motor fan 25 starts the moist air present in the drum to be sucked in via the channel 19 and allows it to flow through the condenser 20.

In the condenser 20, the air in the area 22 is first sprinkled with cold water through the element 27 and expanded then in the area 23. To support this expansion, a diaphragm 26 can advantageously be provided in order to

m rich 22 to be separated from area 23.

The resulting condensation water and the washing water are discharged via line 30 to filter 16 and pump 17. TDlLe presence of water flowing in the same current with the air at the bottom of the condenser 20, especially in the area 23, furthermore promotes the formation of condensation water.

Then the air is led into the channel 23, where it is heated by the resistor 31. The air heated in this way flows to the drum unit 12, where it is again saturated with moisture becomes and covers the same distance again in a closed circuit.

Attention is drawn to the fact that the innovation takes advantage of the construction of a commercial washing machine, simply by adding different elementary parts and by arranging them on the outside in accordance with the innovation of the specially constructed capacitor 20. The capacitor 20 can also be removed from the housing, whereby a Washing and drying machine in an open circuit with inlet and outlet of ambient air is created.

The special design of the condenser triggers an almost continuous expansion of the sucked in, moist air and therefore a good breakdown of the condensation water, and thanks also to the presence of the irrigation and the screen 26, if the same is provided.
