Description

The invention relates to household appliances, in particular to drum-type dryer machines with condensation

by structures.

The purpose of the invention is to improve serviceability.

FIG. 1 shows the machine, a general view; FIG. 2 is the same longitudinal section; on ig. 3 shows section A-A in FIG. 2; in fig. 4 - section B - B in FIG. 2; in fig. 5 is a device for condensing moisture; in fig. 6 is a diagram of the operation of the machine when the cycle is open; in fig. 7 is a section bb of FIG. 6; on fmg, 8 - section G-D in FIG. 6

The dryer dryer (Figs. 1 and 2) includes a housing 1 consisting of front 2 and rear 3 panels, side walls 4 and cover 5. On the outside of panel 2, there is a loading hatch 6, and on the inside — heater 7 and block 8 automatics. At the upper right end of panel 2 there is a QKHO 9 for the passage of air flow reflected by the right flap 10. The latter is a reflective plane made integral with panel 2. In the upper left part of panel 2 there is a left flap 11. Which is also integral with the panel 2 and represents a reflective plane for directing the air flow towards the heater 7. The flaps 10 and 11 are separated by a partition 12. At the bottom of the panel 2, there is an air intake container 13. On the rear panel 3, an actuator 14 rotation of the drum 15 and the fan 16 for circulating air passing through the openings of the disk 17 of the drum 15, and a fan 18 for cooling the air is installed. An air duct 19 for circulating air is provided in the rear panel 3. A partition 21 is installed between the channels 19 and 20. Under the cover 5 of the housing 1 between the side walls 4 there is a fixture 22 For moisture condensation, which consists of pex plates freely installed between front panel 2 and rear panel 3. The first plate 23 of the device 22 is mounted on the side of the drum 16 and has an intake drain groove 24 connected to a condensate-collecting container 13. The plates 25 and 25 are profiled and freely mounted one on another, while the sides of the plates are in contact with the side walls of the housing 1. The front edges adjacent plates on one half of the length of the curved opposite to contact with one another, and on the other

Half of the distance is bent in opposite directions for the same distance. Rear

the edges of the plates, on the contrary, on the corresponding half of the length of the side of the plates are bent in opposite directions and

bent in opposite direction with one another. The spaces between adjacent plates form multidirectional channels for the passage of immiscible flows of circulating 27 and cooled 28 air. The directions of the flows 27 and 28 at the approach and at the exit of the device 22 are parallel to each other. The stack of plates 25 and 26 against displacement is limited by side walls 4 and partitions 12 and 21, and fixed by a lid 5. Against the rear left half 29 of the stack of plates 25 and 26, a channel 20 is located for the cooled air flow leaving the blower 18. Vs

The rear right half 30 of the stack of plates 25 and 26 has a channel 19 for the circulating air flow coming out of the drum 15 through the aperture of the disk 17. The left flap 11 is installed against the front left half 31 of the bag, and the right flap 10 is installed against the front right half 32 of the bag In the rear panel 8, in the zone of location of the blower 18, there is a window 33 for collecting fresh air.

cooled air.

The dryer works as follows.

Wet laundry is loaded into the drum 15 through the loading hatch 6 located in the front panel 2. The automation unit 8 is installed on a predetermined program and the dryer is turned on. The first stage of the dryer operation is the accelerated heating of the wet laundry, which proceeds as follows: the heater 7 and the driver 14 are turned on. The fan 16 draws air through the holes of the disk 17 and through the stirred laundry in the rotating drum 15. Then the flow 27 of circulating air passes through the channel 19 and goes to the back right half of the 30 plate pack. Flow 27 leading to the rear right half of the bag 30 exits in the front left half of the bag 31 and is directed by the left flap 11 to the heater 7. The last heated air stream 27 passes back into the drum 15. Such a circulating movement of the air stream 27 repeats until as long as the laundry is not warmed up to an unstable temperature.

After reaching the required temperature for heating the wet laundry, the clothes dryer enters the second stage of its work. The second stage of operation begins with the inclusion of the blower 18. The activation is carried out by the automation unit 8. At the same time, the cooled air flow 28 flows through the window 33 in the rear panel 3 and is injected by the blower 18 to the rear left half of the plate pack 29. The entire plane of each of the plates of the bag is a dividing wall simultaneously for two different streams and participates in the heat exchange of the moist hot air stream 27 circulating under the action of the fan 16 with the stream of cooled air 28 — which is blown by the blower 18. A stream 28 brought to the back left half of the plate pack 29 exits in the front right half 32 of the pack and, reflected from the flap 10, is removed from the clothes dryer through the window 9 in the upper end of the panel 2. As a result of the contact of the cold 28 and the hot 27 wet air streams circulating inside the clothes dryer under the action of the fan 16, condensate appears on the plates 25 and 26 of the bag, which enters the intake groove 24 of the plate 23 and then enters the condensate trap 13. Air flows to t s long as the laundry reaches a given degree of drying, which is monitored by the humidity sensor. After reaching the required degree

The dryer dryer is automatically shut off. The cyUKWiHd is in a closed cycle, therefore, the breakthrough of humid air into the environment is completely excluded,

With an unclosed 14 cycles, the drying machine (Fig. 6) works as follows. Wet laundry is loaded into the drum 15 through the hatch 6. The automation unit 8 is installed on the required program and the dryer is turned on. The first stage of the dryer operation is accelerated heating of the wet laundry, which proceeds as follows: the heater 7 is turned on and the drive

5 14. The fan 16 draws air through the holes of the disk 17 and through the stirred laundry in the rotating drum 15. Next, the air flow 27 passes through the channel 19 and enters the rear right half of the 30-pack of plates. The air flow supplied to the rear right half of the package 30 comes out in the front left half of the package 31 and is directed by the left stator 11 to the heater 7, having passed it, the air

5, the flow, already heated, returns to the drum 15. This movement of the air flow is repeated even until the laundry has reached the required temperature. After the required temperature of warming up the wet laundry has been reached, the dryer enters the second stage of its work, which begins with turning two interlocked flaps 10 and 11 at an angle of 90 ° around the common axis. Remove moisture from warmer with heated

5, the air flow is sucked through the apertures of the disk 17 and flows to the back right half of the 30 plate pack. Wet air flow to the rear right half of the 30 pack goes into

0 front left half of the 31 plate pack. The entire plane of each of the plates of the bag is a demarcation wall for two different streams simultaneously and participates in the heat exchange of a moist hot air stream with cold fresh air entering the clothes dryer through the window 33. Condensate is released as a result of the contact of the streams on the plates 25 and 26 which flows down the intake piping 24 of the effluent into the condensate collection tank 13. Next, the already dried air flows out in the front left half of the bag 31 and is directed by the left flap 11 into the window 9 for removal howling dryer

5 exhaust air. The exhaust air from the heat exchange that takes place in the condenser is cooled and dried. Fresh air enters the clothes dryer through the window 33, made in the rear panel 3 against the rear left half 29

package i exit1 t in the front right half of the 32 package. As a result of the heat exchange that takes place in the condenser 22. fresh air is preheated and directed by the right flap 10 to the heater 7. Next, the already hot air enters the drum 15. The movement of the air flow when fresh air enters the laundry dryer The window 33 in the rear panel 3, and the exhaust air is removed from the laundry cyujnnKM to the window 9 of the upper end of the front panel 2, occurs until the laundry reaches a predetermined degree of drying. The degree of drying is monitored by a humidity sensor. After the required degree of drying has been achieved, the dryer is automatically switched off.

The proposed drying machine allows to significantly simplify maintenance and repair,
