Definitions

  • the invention relates to a dryer, in particular for laundry, with a control system with valve flaps for controlling the supply, exhaust and circulation air quantities which can be transported by means of a blower for the drying process in a dryer drum.
  • a control system with valve flaps only for the exhaust air quantities of a dryer is known from DE-OS 36 00 059. Dryers with such control systems are also known, in which, however, the valve flaps are located at different points of the dryer for controlling the individual air quantities, which entails a correspondingly large structure of such dryers.
  • the object of the invention is to achieve a smaller size, that is to say smaller dimensions, in such dryers.
  • control system has a coherent valve space which is divided into a first and a second valve sub-space by means of a partition, at least the first valve sub-space being formed from a valve chamber which is essentially closed to the environment has at least one blow-in opening which is connected to the blower outlet of the blower, which is connected to the interior of the drum via its suction inlet side, and which has at least one exhaust air opening which connects the valve chamber to the surroundings, that the second valve sub-chamber has at least one suction opening which connects the surroundings with the inside of the drum, that at least one first or second valve flap is present at least for the opening and closing of the suction and blowing opening, which can be moved at least into an open position and into a closed position via at least one controllable drive are that the first valve flap opens at least the flow path from the inlet opening to the drum interior or in its closed position to the exhaust air opening in one of its opening positions and the second valve flap opens the flow path from the surroundings via the suction opening to the
  • the entire control system for controlling the amounts of air to be transported is combined in a valve space, into which all channels for the air flow open, so that from there the drying process can be controlled centrally, that is at one point, by means of valve flaps.
  • a control system is very small and therefore also reduces the overall size of the dryer.
  • the first valve flap divides an increasing proportion of the flow quantity which can be blown in via the blower opening for the outlet from the exhaust air opening with decreasing open position up to its closed position.
  • the required drying air is heated by a heat exchanger serving as a heater and sucked through the drum by means of the blower. This creates a vacuum inside the drum, which should support the evaporation of the water from the laundry.
  • the first valve flap can be actuated accordingly in the direction of its closed position, depending on the increase in pressure, the flow rate causing the pressure rise is released to the exhaust air opening, so that the negative pressure inside the dryer can be maintained.
  • the first valve flap in each of its positions exposes an opening in the partition which connects the interior of the drum to the surroundings via the first valve chamber and the suction opening of the second valve chamber when the second valve flap is in one of its open positions.
  • the heat exchanger is arranged over the entire circumference of the inflow openings which can be released by the first and second valve flaps in one of their open positions towards the inside of the drum.
  • the second valve flap when the second valve flap is in one of its opening positions, the ambient air can also be conducted into the interior of the dryer via the first valve chamber and the part of the heat exchanger located below, through the suction opening and the opening in the partition, so that when the fan is operating for the inflowing air from the environment has a larger heating surface of the heat exchanger serving as a heater, which means that a higher efficiency and thus comparable dryer performance compared to known dryers can be used with a smaller heat exchanger, which in turn enables a reduction in the overall size of the dryer.
  • the drive moves the two valve flaps in opposite directions during their pivoting movements when opening and closing. This enables precise control of the quantity of the ratio of fresh air supplied from the environment and the amount of circulating air circulated inside the dryer by means of the fan. Because depending on the position of the valve flaps, which can be controlled depending on each other, the quantities of fresh air supplied and circulated recirculated air and the exhaust air change.
  • the drive controls the first and second valve flaps together. This results in a positive coupling of the valve flaps which can be moved in opposite directions, so that a faulty control of the control system is largely excluded.
  • a third valve flap which can be controlled by a drive is provided for opening and closing the exhaust air opening. This allows you to control the amount of exhaust air exiting through the exhaust air opening.
  • the blow-out opening is continuously connected for blowing out the laundry from the drum after the drying process via at least one channel with the end face of the dryer drum which is open towards the input side.
  • the flow rate controlled by the exhaust air opening via the blow-out opening can be used to blow the laundry out of the dryer drum after the drying process has ended.
  • the second valve sub-space is a second valve chamber which corresponds essentially to the first valve chamber and forms a part of the channel used for blowing out the laundry, which is closed off from the environment via a shut-off part which is firmly connected to this valve flap, regardless of the valve position of the second valve flap is.
  • the blower is the two for sound and heat insulation
  • Valve chambers and the heat exchanger comprises a housing which has a continuous opening which connects the surroundings with the interior of the drum. In this way it can be achieved that during operation of the fan, a portion of the fresh air in the environment is sucked into the interior of the drum by the negative pressure prevailing there, which is sufficient to prevent the propagation of sound and thus the generation of noise and which serves as an energy collecting hood Exhausts the heat generated inside the drum for the drying process.
  • At least one of the two valve flaps preferably the first valve flap, is arranged in such a way that in each of the flap positions it can hold, it is oriented at least with a part of its total area substantially parallel to the direction of flow.
  • the direction of flow is determined by the flow volume of the fan, which is led into the valve chamber via the injection opening.
  • this is the amount of flow that flows from the environment into the interior of the valve chamber via the suction opening. This achieves a largely laminar flow of the flow rates at the valve flaps, which ensures that the flow rates are forwarded to the intended locations of the dryer without the occurrence of turbulence in the valve chamber.
  • This also makes it possible to pivot the valve flaps with little effort, which protects the drive mechanism of the valve flaps and what allows the use of drives with low power.
  • At least the first and the second valve flap are arranged in such a way that in the inflow direction these valve flaps, in each flap position they can occupy, oppose the flow only with a small effective resistance area of their total area, preferably with their end faces facing in the direction of the inflow direction .
  • At least the first valve flap is designed in the shape of an airfoil, in particular with an upward curvature.
  • FIG. 1 shows a dryer, designated as a whole by 10, which is mounted on supports 12.
  • a dryer drum 16 Arranged in the housing 10 is a dryer drum 16 which can be rotated about an axis 14.
  • the dryer drum 16 has openings on its outer circumference 18 for the passage of air and / or water vapor in a known and therefore not shown manner. For reasons of simplification, only air transport is addressed in the following. However, this implies that water vapor, as far as it arises, can be transported accordingly by the facilities.
  • the dryer 10 is essentially divided into a lower part 20 and an upper part 22.
  • the lower part 20 of the dryer 10 is surrounded by an insulating jacket 24 for sound and heat insulation.
  • the dryer drum 16 is located in the interior 26 of the dryer, which can be connected to the upper part 22 of the dryer 10 via channels 28 and 30 for the air inlet and outlet.
  • a fluff filter 32 is arranged between the interior 26 of the dryer 10 and the duct 30 for the air outlet.
  • the upper part 22 of the dryer 10 essentially consists of a heat exchanger 34 serving as a heating element, a blower 36 and a valve chamber 38 with three valve flaps 40, 42 and 44.
  • the valve chamber 38 consists of two connected valve chambers 50 and 52, which are divided by means of a partition 48.
  • the valve chamber 38 is essentially a cuboid box made of sheet metal with a square cut, which is placed on the heat exchanger 34 and which, with its five outer sides, closes off the interior of the valve chambers 50, 52 from the surroundings.
  • the first valve chamber 50 has an injection opening 54 on the front side 53 of the valve chamber 38 facing the blower 36, which is connected to the blower outlet 56 of the blower 36.
  • the fan 36 is connected with its air intake side 58 via a duct 60 (FIG. 1) to the duct 30 for the air outlet and thus to the interior 26 of the dryer 10.
  • first valve chamber 50 On the side of the first valve chamber 50 opposite the injection opening 54 there is an exhaust air opening 62 in the rear wall 64 of the valve chamber 38.
  • This exhaust air opening 62 leads to the outside (surroundings) by means of a chimney 66.
  • the underside 68 of the first valve chamber 50 facing the heat exchanger 34 forms a first inflow opening 70 which opens into the air inlet channels 71 of the heat exchanger 34 which are divided by the heating rods 69 and which in turn open into the air inlet channel 28, so that an air-permeable connection of the first valve chamber 50 is provided the interior 26 of the dryer 10 is possible.
  • the second valve chamber 52 which essentially corresponds to the first valve chamber 50 with regard to the chamber volume, has on its side facing the blow outlet 56 of the blower 36 a suction opening 80 in the front side 53 of the valve chamber 38 which essentially corresponds in cross section to the blow-in opening 54.
  • This suction opening 80 for the fresh air supply leads to the outside (surroundings).
  • the cross section of this suction opening 80 can be enlarged if a triangular cutout 80a, which can be covered by the second valve flap 42, is provided in the outer wall 115 of the second valve chamber 52 facing the loading side.
  • the underside 72 of the second valve chamber 52 facing the heat exchanger 34 forms a second inflow opening 74 that is comparable to the first inflow opening 70 and, like the first inflow opening 70, is connected to the interior 26 of the dryer 10.
  • the two inflow openings 70 and 74 are communicatively connected to one another.
  • the partition 48 has in its lower part facing the heat exchanger 34 an opening 76 which extends over its entire length.
  • two valve flaps 40 and 42 Arranged in the two valve chambers 50 and 52 are two valve flaps 40 and 42 which can be pivoted about a shaft 96 and 112, respectively, which essentially runs parallel to the drum axis 16, in order to open and close the two inflow openings 70 and 74. In its closed position 75 shown in FIG.
  • the first valve flap 40 pivotably arranged in the first valve chamber 50 closes the first inflow opening 70 from above and completely clears the way from the blowing opening 54 to the exhaust air opening 62.
  • the path between the first inflow opening 70 and the blow-in opening 54 for blowing in the air from the blower 36 is completely open and the path between the blow-in opening 54 and the exhaust air opening 62 is blocked.
  • the opening position of the first valve flap 40 decreasing until it closes, an increasing proportion of the amount of air that can be blown in by means of the blower 36 via the blowing opening 54 is divided for the exit from the exhaust air opening 62.
  • the first valve flap 40 has an upwardly curved shape and, with its underside facing the interior 26 of the dryer 10, releases the opening 76 already described in the partition 48 in each of its positions, also in its closed position 75.
  • the second valve flap 42 pivotably arranged in the second valve chamber 52 closes the second inflow opening 74 from above and thus blocks the supply of fresh air via the suction opening 80 into the interior 26 of the drum 10. If the second valve flap 42 is in one of its open positions (FIGS. 2, 3 and 5), it gives the way for the fresh air supply from the suction opening 80 free into the interior 26 of the drum 10 via the second inflow opening 74.
  • the path for the fresh air is opened via the suction opening 80 and the opening 76 of the partition 48 into the subspace of the first valve chamber 50 which is separated from the lower side of the first valve flap 40 towards the first inflow opening 70.
  • the second valve flap 42 is essentially flat.
  • a pressure cylinder 88 is provided as a common drive for the two valve flaps 40 and 42, which actuates the two valve flaps 40 and 42 via a lever linkage designated as a whole as 90.
  • the lever linkage 90 consists of a drive rod 92 which is articulated at one end to the piston rod 94 of the pressure cylinder 88 and which is firmly connected at its other end to a shaft 96 (FIG. 8).
  • the first valve flap 40 is fixedly attached to this shaft 96 by means of a screw connection 98.
  • the shaft 96 is guided by means of plain bearing bushes 100 in the outer wall 102 of the first valve chamber 50 opposite the partition 48 and in the partition 48 itself.
  • a connecting rod 106 is firmly connected at one end to the shaft 96 via a further screw connection 104.
  • a clamping screw 108 is articulated, which connects the end of the connecting rod 106 to the one end of a web 110 with which the second valve flap 42 is fixed is bound.
  • the clamping screw 108 is provided to make the distance from the connecting rod 106 to the web 110 correspondingly adjustable to one another in order to better coordinate the opposite movement of the two valve flaps 40, 42.
  • a fixed rod (not shown) can also be used as a connecting member instead of the tensioning screw 108.
  • the second valve flap 42 is V-shaped and is connected to the second valve chamber 52 so as to be rotatable about an axis 112 which is mounted in the partition wall 48 and in the outer wall 115 opposite the partition wall 48 by means of slide bearing bushes 114. If the cylinder 88 shown in FIG. 7 is now actuated, its piston rod 94 extends and pivots the drive rod 92 counterclockwise, so that the first valve flap 40 firmly connected to it moves out of its closed position 75 shown in FIG. 7 into one of its open positions (Fig.4) swiveled. As a result of this movement of the drive rod 92, the connecting rod 106 is likewise moved counterclockwise around the shaft 96 in FIG.
  • the second drive designated as a whole by 116, has a pressure cylinder 118 (FIG. 7) with a piston rod 120, to which a drive rod 122 is articulated at one end and engages at its other end on a shaft 124 which is comparable to shaft 96 is mounted in the outer wall 102 and the partition 48.
  • the third valve flap 44 which essentially forms a flat plate, is fixedly connected to this shaft 124.
  • a triangular blow-out opening 126 is cut into the partition 48 and connects the first valve chamber 50 to the second valve chamber 52.
  • the third valve flap 44 On the side facing the partition 48, in order to cover this triangular blowout opening 126, the third valve flap 44 has a triangle 128 which is somewhat larger than the triangle opening and is designed as a plate and which, in the fully open position of the third valve flap 44, closes this triangular blowout opening 126 and in its position closing the exhaust air opening 62 releases this blow-out opening 126 again.
  • 7 shows the third valve flap in its fully open position, in which it completely clears the exhaust air opening 62.
  • the piston rod 120 By actuating the pressure cylinder 118, the piston rod 120 is retracted and the drive rod 122 moves around the shaft 144 in a clockwise direction, so that the third valve flap 44, which is firmly connected to the shaft 124, is also moved in a clockwise direction to close the exhaust air opening 62, and the triangular blow-out opening 126 releases in the partition 48.
  • An opening 130 corresponding to the triangular blow-out opening 126 is cut into the outer wall 115 of the second valve chamber 52 on the front side of the entrance opening 131 to the drum 16 (FIG. 9). Attached to this opening 130 is the blow-out hose 132 shown in FIGS. 9 and 2, which is connected in a known and therefore not shown manner via inflow openings 134 to the inside of the drum.
  • connection of the two triangular openings 126 and 130 is achieved via the rear chamber part 136 of the second valve chamber 52.
  • the front chamber part 138 facing the suction opening 80 is completely separated from the rear chamber part 136 of the second valve chamber 52 via a shut-off part 140 firmly connected to the second valve flap 42 and via the chamber wall 141 drawn in between.
  • FIGS. 3 to 5 The functions of the three valve flaps 40, 42 and 44 for a drying process are now explained below with reference to the figures, in particular FIGS. 3 to 5.
  • Fig. 3 the flap position is shown, as it is usually set at the beginning of a drying process.
  • the second valve flap 42 is fully open and clears the way for the fresh air from the surroundings of the dryer via the suction opening 80 to the second inflow opening 74 and via the opening 76 of the partition 48 to the first inflow opening 70.
  • the fresh air is introduced into the interior by the vacuum 26 generated by the fan 36 in the interior 26 of the dryer 10 via the first and second inflow openings 70 and 74 through the channels 71 over the entire heatable surface of the heat exchanger 34 and the air inlet channel 28
  • the dryer drum 16 is conveyed and from there it is sucked back into the fan 36 via the fluff filter 32, the air outlet duct 30 and the suction duct 60. From there, the air sucked in via the shaft 60 is again completely released into the open via the blowing opening 54 and the exhaust air openings 62 when the first valve flap 40 is in its closed position 75. In this way, all of the air drawn in via the suction opening 80 by the fan 36 is released into the open again via the exhaust air opening 62.
  • the second valve flap 42 is closed, fresh air can no longer flow into the interior 26 of the dryer 10 via the suction opening 80. Rather, the amount of air in the dryer is now circulated 100% by means of the fan 36 when the valve flap 40 is fully open and blocks the path to the exhaust air opening 62.
  • the flow path is the following. The air is transported via the first outlet opening 70 and the air inlet channels 71 of the heat exchanger 34 to the air inlet channel 28 via the blow outlet 56 and the blow-in opening 54 and from there, as already described, is brought back into the blower interior for a new circulation process, as already described.
  • valve flaps 40 and 42 assume an intermediate position between the maximum possible opening and closing position, the air flow blown into the first valve chamber 50 is divided by the first valve flap 40 and part of the air is divided by the degree of the opening position the first inflow opening 70 into the interior 26 of the dryer 10 and the other portion transported to the exhaust air opening 62. If the first valve flap 40 is in such a position, the second valve flap 42 which is positively coupled to it is also in one of its open positions and thus opens the second inflow opening 74.
  • the fresh air supplied via the suction opening 80 is then increased into the interior through the opening 76 in the partition 48 by means of the flow generated by the blower 36 which passes through the first inflow opening 70 26 of the drum 10 sucked in, so that, on the one hand, together with the portion of the part sucked in via the suction opening 80 into the second inflow opening 74 into the interior 26 of the dryer 10, the entire surface of the heat exchanger for heating the supplied fresh air is fully utilized and, on the other hand, that Inflow of the air via the suction opening 80 is facilitated, which reduces the inflow of fresh air that can be fed into the Drum inside increased. It is advantageous if the flow direction at the blower outlet is aligned with the fresh air flowing in via the suction opening 80, which is ensured by the structural design of the valve chambers 50, 52 with their openings for the air passage.
  • valve chamber 38 and the two valve flaps 40 and 42 arranged there any quantities of fresh air can be mixed exactly with the circulating air portion in the system and that there is an exhaust air discharge maintaining the vacuum inside 26 of dryer 10.
  • the entire surface of the heat exchanger 34 can be used to heat the fresh air for the drying process.
  • the third valve flap 44 is pivoted in front of the exhaust air opening 62 by means of a separately controllable drive 116 and the flow path from the blowing opening 54 to the outside (surroundings) is thus blocked.
  • the third valve flap is pivoted downward, the triangular blow-out opening 126 is opened.
  • the first valve flap 40 is wide open in its closed position 75 and the second valve flap 42 for the supply of a high proportion of fresh air.
  • the second valve flap 42 has the shut-off part 140 and the second valve chamber 52 has the dividing wall 141 with which the front chamber part 138 is shut off from the rear 136 of the second valve chamber 52.
  • the second valve chamber 52 would be unnecessary and the second valve flap 42 would not require a shut-off part 140. Then the second valve chamber 52 could be formed by the environment.
  • the underside of the heat exchanger 34 is closed off from the inside of the drum in a known and therefore not described manner by fins 133 and by an end plate 137 (FIG. 1) which can be driven by a drive 135. In this way, it is prevented that air can flow back into the valve chamber 38 via the air inlet channel 28 during blowing out, which could hinder the blowing out process.
  • this has a housing 150 with an upper and a lower housing half 152 and 154.
  • the lower housing half 154 essentially forms a box-shaped frame for the heat exchanger 34 and the shaft 60 of the blower 36.
  • This lower housing half 154 opens upwards to an opening for receiving the lower edge of the upper housing half 152, which sits on the valve chamber 38 and essentially covers this and the fan 36.
  • the two housing halves 152 and 154 delimit a completely circumferential gap 156. This gap 156 serves to ensure that air can continuously flow from the surroundings into the interior 26 of the dryer 10 when there is negative pressure.
  • the air flowing through the gap 156 on the one hand suppresses the sound emissions of the blower 36, on the other hand it absorbs the radiated heat of the heat exchanger 34 and accumulates as it rises in the upper housing half 152 serving as an energy collecting hood, from where it depends on Flap position and operating state of the dryer inside its 26 is continuously discharged, which leads to a reduction which leads to heat in the vicinity of the dryer.
  • the two housing halves 152 and 154 can, as shown in FIG. 1 for the lower housing half 152, be provided with insulation 158.
  • valve flaps 40 and 42 can be controlled in such a way that the second valve flap 42 is always slightly open, so that the air from the gap 156 is constantly at it can flow into the second inflow opening as long as the fan 36 is operating. It is also conceivable that the second inflow opening 74 is slightly larger in cross section than the second valve flap 42, so that this measure also ensures that air can constantly flow into the interior 26 of the dryer via the gap 156.
  • the pressure increase in the interior 26 of the dryer 10 which is brought about by the supply of a fresh air quantity portion via the gap 156 can then be reduced by the opening position assumed by the first valve flap 40 closer to its closed position 75, in which the correspondingly supplied quantity portion by division of the via the first inflow opening 70 separated by the fan recirculated air and is released to the exhaust port 62. In this way, a constant negative pressure can be achieved in the dryer.
