Description

Condenser dryer

The present invention relates to a household condenser for a laundry, comprising a rotating drum for receiving laundry to be dried, a hot air generator circulating within said drum, and a steam generator for supplying steam to said drum, and more specifically to a supply system steam generator with water.

The condenser dryers of the type mentioned above are known, but all are designed with the demanding arrangement of the condensate distribution pipes, which makes it difficult to manufacture the dryer in question.

It is an object of the invention to create a condenser for a laundry which eliminates the disadvantages of the known solutions.

The task according to the invention is solved by the fact that in the area above the drum for receiving laundry, which is dried or dried. softens, arranged condensate storage tank or. distilled water. The condensate is supplied from the condensate receiver by means of a pumping means to said vessel via the condensate line. Said container comprises an inlet opening away from the drum, through which the condensate water is fed through the first branch of the condensate. Further, said container is designed with a vertical tunnel into which a second condensate water outlet extends and through which the condensate flows into a channel designed below said vessel.

• · ·

The above described connection between the condensate line and the container is designed in such a way that a large portion of the condensate flowing through the conduit is poured, while a smaller portion of the condensate flows through said tunnel past the vessel into said channel below the latter and downstream into the water container.

The invention will now be described in more detail by way of an embodiment and on the basis of the accompanying drawings, in which FIG. 1 is a schematic diagram of a laundry condenser according to the invention; 2 is a schematic three-dimensional view of the condensate vessel; FIG. 3 is a cross-section through a condensate vessel through plane III.

The laundry condenser according to the invention consists of a housing 1 in which a rotating drum 2 is arranged to receive the dryer to be dried. In the area under said drum 2 is arranged a condenser 3 under which is located the first blower 4, which pushes the flow of Ti cooling air through said capacitor 3, and cools from the drum 2 the flowing stream T ₂ hot and humid air taken from the laundry, which it dries it. A condensate is discharged from the condenser 3 through which a condensate is discharged from said stream T ₂ , which flows further down the condensate line 6 into the condensate receiver 7. In said condensate receiver 7, a pumping means 8 is arranged, which pushes the condensate through the conduit 9 into a container 10 arranged in the area above said drum.

2. Said pumping means 8 is, in a manner known per se, controlled by the electronic control of the condenser dryer of the invention.

In the extension of said channel 5, a second blower 11 is arranged, which pushes the flow T _{3 of the} air flowing from the condenser 3 through the channel 12 and through the heater 13 into said drum 2. Said blowers 4, 11 are preferably arranged on the same axis and simultaneously driven by a single drive unit 14. Further, in the area under said drum 2, a steam generator 15 is arranged, which is supplied with water, preferably distilled water, by a pump 16, which draws said water from a container 17 of water arranged at the same level in the neighborhood of the condensate receiver 7. . Said water container 17 is charged via the supply line 18 from said water tank 10 above the drum 2. A water sensor 19 is arranged in the water container 17, which, in case of low water level in said container 17, sends an appropriate signal to the display on the control panel of the condenser dryer, thereby alerting the user to low water levels. In such a case, the user, preferably, · · · · distilled water, must top up himself into said container 10 disposed above the drum 2, from where the water through the supply line 18 flows into said container 17. When said container 17 is fully filled, pour excess water downstream 20 into said receiver 7.

Said air flow T ₃ is either dry or moist depending on the mode of operation of the condenser. If the condenser is used to dry the laundry located in the drum 2, said stream T _{3 of the} air is substantially completely dry and is further heated by said heater 13 in channel 12. However, if said condenser according to the invention is used for softening or. refreshing the laundry, said stream T _{3 of the} air is moist and moistened by steam generated by the generator 15. The steam thus generated through the nozzle 21 enters said channel 5, after which the blower 11 pushes said stream of moist air ₃ through the channel 12 into the drum 2. The said heater 13 is not active in this case.

The above-mentioned container 2 is arranged above the drum 2 in which the condensate or the condensate is stored. distilled water is designed as a fully enclosed reservoir designed on the upper side away from the drum 2 facing side with an inlet 22 for condensate delivery, with which the first condensate inlet 23 from the conduit 9 cooperates, through which a pump 8 is supplied condensate from said condensate receiver 7. Said first condensate inlet 23 is essentially the first outlet of said conduit 9, and after said first outlet of said condensate conduit 9, a larger portion of the inlet condensate flows through the container 10. According to the invention, it is envisaged that said larger portion of the condensate represents about 2/3 of the total amount of condensate supplied by the pumping means 8 through the conduit 9. According to the invention, it is further provided that said container 10 is formed by a funnel tunnel 24, which is preferably oriented in a vertical direction. Entering the tunnel 24 at said upper, away from the drum 2 facing side of the container 10, cooperates with a second condensate inlet 25 from the conduit 9, after which a condensate is supplied from said condensate receiver 7 by means of a pumping means 8. Said second condensate inlet 25 is essentially a second branch from said conduit 9, whereby, after said second branch from said condensate conduit 9, a smaller portion of the condensate inlet flows through the container 10 through said vessel 10. According to the invention, it is envisaged that said smaller portion of the condensate represents about 1/3 of the total amount of condensate delivered by the pumping means 8 through the conduit 9.

The said smaller fraction flows through the second inlet 25 of the incoming condensate after the said • · · · • ·

tunnel 24 through the vessel 10 and is poured into the channel 26 on its lower side, facing the drum 2 and at the outlet of said tunnel 24, which is hydraulically connected to the supply line 18 through which it is distilled with water or. condensate is filled by said container 17.
