Definitions

  • Embodiments of the present disclosure relate to a dryer provided with a heat pump cycle, and more particularly, to a dryer provided with a structure capable of discharging condensed water generated from an evaporator.
  • a dryer to dry clothes is provided with a heat pump cycle including a compressor, a condenser, and an evaporator.
  • the dryer as such has a blower passage that allows an air stream to pass in the order of the condenser, a drum to accommodate wet clothes, and the evaporator through a blower.
  • the dryer is configured such that the air stream circulated or taken is heated in the condenser, and the moisture of the clothes in the drum is evaporated by the heat of the heated air, while the evaporator collects the heat from the air that has acquired a large amount of moisture by passing through the drum. However, if the evaporator collects the heat from the air, the temperature of the air is lowered, so the moisture contained in the air is condensed, producing condensed water.
  • the condensed water is temporarily stored in a condensed water storage installed at a lower portion of the dryer or the evaporator, and is discarded by a user at a later time, or, if the dryer is configured as an integral unit with a washing machine, is discharged together with the washing water.
  • a drain mechanism is provided at a floor of the room where a washing machine or a dryer is installed, so the condensed water is flown downward by gravity from the condensed water storage to a drain-outlet.
  • a washing machine or a dryer is commonly installed at a basement where a drain mechanism such as a drainage fan is not installed. Accordingly, in order to have the condensed water of the dryer to flow through a drainpipe that is installed near to the ground, the condensed water needs to be pumped upward about 3 meters to be near the ground.
  • a technology of pumping condensed water W, while the height of water raised is low, is disclosed in the Japanese Unexamined Patent No. 2006-087672 that includes a drain mechanism in which a drain pump 6 raises the condensed water W stored in a condensed water storage 3 (see FIG. 5 ) to a height where a drum 14 is installed, such that the condensed water W is dropped and flown at an inside a drain hose 7 connected to a drain-outlet of the floor.
  • a structure of raising the condensed water W through a drain pump (see FIG. 6 ) disclosed in the Japanese Unexamined Patent No. 2006-087672 has a drain mechanism including a water storage tank 3 to store the condensed water W at a lower portion of the evaporator 13, and a drain pump 6 using a high power to raise the condensed water W by 3 meters at the point of time when the condensed water W is fully filled in the water storage tank 3 and to drain the condensed water W.
  • the drain mechanism as such has the following drawbacks.
  • the water storage tank 3 is configured to store the condensed water W, which is generated from the evaporator 13, in a manner to drop the condensed water W by gravity.
  • the storage tank 3 is needed to be installed at a lower portion of the drum 14 or the evaporator 13. Since the height of the drum 14 is established in advance due to the limitation for use, the height of the water storage tank 3 is difficult to be increased as a means to enlarge the volume available for storage, thereby resulting in the smallness of the volume of the water storage tank 3.
  • the condensed water (W) fully filled and stored in the water storage tank 3 is drained through the drain hose 7 by the drain pump 6 using a high power, but as shown in (b) of FIG. 6 , at the point of time when the condensed water W is completely drained from the water storage tank 3, the drain pump 6 is needed to be stopped to prevent the idling, the malfunction, or the noise.
  • the stopping of the drain pump 6, commonly having a length of about 3m and an inner diameter of about 13mm causes a large amount of condensed water W, for example, 0.4L to return back to the water storage tank 3.
  • the drain tank 3 starts the draining, most of the water storage tank 3 makes a dead volume, causing the condensed water W to be kept stored without being drained, so that the amount of condensed water W to be stored is becoming reduced.
  • the volume of the water storage tank 3 acting for draining is reduced, so that the water storage tank 3 is rapidly filled with the condensed water W, while having a demand for operating the drain pump 6 in more frequent manner. Since the ON/OFF frequency per unit time is increased, the drain pump 6 is broken earlier. In addition, noise is increased due to the frequent operation of the drain pump 6 using a high power.
  • German patent application DE102008041832 discloses a device wherein condensed water is collected at a sink, which then subsequently flows through a fibrous material filter into a condensate container.
  • a dryer 100 in accordance with the first embodiment of the present disclosure uses a heat pump cycle 1 including a compressor 11, a condenser 12, and an evaporator 13, and is configured to dry wet clothes.
  • the dryer 100 is provided with a blower passage 2 that allows an air stream to pass through in the order of the condenser 12, a drum 14 to accommodate clothes, and the evaporator 13.
  • the air stream is formed by a blower mechanism 14 installed at a lower portion of the evaporator 13. According to the configuration as such, the air stream is heated by the heat received from the condenser 12, and evaporates moisture in the clothes in the drum 14. The air stream containing the moisture is exhausted from the blower mechanism 15 while being deprived of the heat at the evaporator 13. In addition, as the temperature of the air stream is lowered, condensed water S is condensed at the evaporator 13.
  • the dryer 100 in accordance with the first embodiment of the present disclosure is provided with a drain mechanism 200 to discharge the condensed water W generated at the evaporator 13 to an outside.
  • the draining of the dryer 100 is not performed toward a drain-outlet that is positioned lower than the dryer 100, but is performed by raising condensed water W to a drainage portion that is installed higher than the dryer 100 by about 3 meters and by discharging the condensed water W.
  • the drain mechanism 200 includes a first water storage tank 3, a delivery pump 4, a second water storage pump 5, a drain pump 6, and a drain hose 7 that are installed from the evaporator 13 to a drainage portion to an outside the dryer 100.
  • the drain mechanism 200 is provided with a drain control unit (not shown) to control the delivery pump 4 and the drain pump 6.
  • the components of the dryer 100 will be described in brief.
  • the first water storage tank 3 is configured to temporarily accommodate the condensed water W generated at the evaporator 13.
  • the condensed water W is delivered by the delivery pump 4 from the first water storage tank 3 to the second water storage tank 5 at the point of time when the condensed water W is fully filled in the first water storage tank 3 or reaches a predetermined amount.
  • the delivery of the condensed water W is repeated in a number of times, and if the condensed water W is fully filled in the second water storage tank 5 or reaches a predetermined amount, the condensed water W is discharged by the drain pump 6 or by the drain hose 7 of an outside the dryer 100.
  • the drain hose 7 has one end opening at a position higher than the installation position of the second water storage tank 5 by about 3 meters, and the other end installed at the drain pump 6.
  • the first water storage tank 3 connects between an evaporator case 131 to accommodate the evaporator 13 and the drain pump 6 through a pipe.
  • the first water storage tank 3 is installed at a lower side of the evaporator 13. That is, the water droplets of the condensed water W generated at the evaporator 13 is collected at the first water storage tank 3 through a movement by gravity.
  • the first water storage tank 3 is provided in a rectangular parallel-piped shape available to be accommodated a lower side of the evaporator 13 inside a housing of the dryer 100.
  • the first water storage tank 3 has a volume smaller than the second water storage tank 5, that is to be described later, and is sufficiently small to be disposed at a position suitable for collecting the condensed water W from the evaporator 13.
  • a first water level detection unit 31 is provided at an upper side of the first water storage tank 3 to detect whether the condensed water W is fully filled or reaches a first predetermined amount in the first water storage tank 3.
  • a liquid level detecting sensor may be used as an example of the first water level detection unit 31.
  • the first water level detection unit 31 in accordance with the embodiment serves to detect whether a water level of the first water storage tank 3 corresponds to the first predetermined water level, but the present disclosure is not limited thereto, and the first water level detection unit in accordance with another embodiment may sequentially detect other water levels.
  • the delivery pump 4 is a small capacity-compact type pump when compared to the drain pump 6 that is to be described later, and is configured to deliver the condensed water W from the first water storage tank 3 to the second water storage tank 5.
  • the delivery pump 4 has a capability to raise the condensed water W to a position of the housing of the dryer 100, but lower than 3 meters.
  • the second water storage tank 5 is installed at a portion assuring a large space while avoiding the lower side of the evaporator 13 inside the housing of the dryer 100, so as to have a volume larger than that of the first water storage tank 3. If the first water storage tank 3 has a volume of about 0.1L, the second water storage tank 5 may have a volume of about 1.0L. That is, the second water storage tank 5 is configured to have a volume about ten times larger than that of the first water storage tank 3.
  • the first water storage tank 3 and the second water storage tank 5 have sizes set based on an assumption, as shown in FIG.
  • the second water storage tank 5 is also configured to a rectangular parallel-piped shape, and a second water level detection unit 51 is installed at an upper side of the second water storage tank 5 to detect whether the condensed water W is fully filled or reaches a second predetermined amount in the second water storage tank 5.
  • a liquid level detecting sensor may be used as an example of the second water level detection unit 31.
  • a water level detector or a water quantity detector may be used as an example of the second water level detection unit 31.
  • the second predetermined level is provided at a position lower than a maximum water level of the second water storage tank 5 by a predetermined level, such that the second water level detection unit 51, while the condensed water W is being discharged from the drain hose 7 to an outside by the drain pump 6, absorbs the condensed water W in spite of a backflow of the amount of a volume of the condensed water W contained in the drain hose 7, that is, the amount of a volume of the drain hose 7.
  • an opening is provided at an upper surface of the second water storage tank 5 to discharge the inside air to an outside even if the condensed water W is introduced into the inside the second water storage tank 5.
  • An air discharge pipe 52 is installed at the opening. The air discharge pipe 52 is installed so as to join the drain hose 7 at a position which is higher than the maximum water level of the second water storage tank 5.
  • the drain pump 6 has a capability to raise the condensed water W collected in the second water tank 5 by 3 meters, and to discharge the condensed water W to an outside. That is, when compared to the delivery pump 4, the drain pump 6 has a higher head and a larger flow rate.
  • the delivery pump 4 has a head of about 0.5m and a flow rate of about 0.5L/min, while the drain pump 6 has a head of about 3m and a flow rate of about 10L/min.
  • the drain control unit is configured to control the operation of the delivery pump 4 and the drain pump 6, and is implemented using a computer or a microcomputer provided with input/output parts, for example, a central processing unit (CPU), a memory, and an A/D converter.
  • the drain control unit is configured to operate the delivery pump 4 or the drain pump 6 for a first predetermined time in a case when the water level of the first water storage tank 3 is detected as the first predetermined water level by the first water level detection unit 31, such that the condensed water W is delivered from the first water storage tank 3 to the second water storage tank 5, and to operate the drain pump 6 for a second predetermined time in a case when the water level of the second water storage tank 5 is detected as a second predetermined water level by the second water level detection unit 51, such that the condensed water W is discharged from the second water storage tank 5 to an outside.
  • the first predetermined time represents a time taken for the water level of the first water storage tank 3 to change from the first predetermined water level to nearly zero as the delivery pump 4 is driven, and the first predetermined time may be set through an experiment.
  • the second predetermined time represents a time taken for the water level of the second water storage tank 6 to change from the second predetermined water level to nearly zero as the drain pump 6 is driven, and the second predetermined time may be set through an experiment.
  • the draining operation is controlled not on the basis of the water level measured when the delivery pump 4 and the drain pump 6 having been operated are stopped, but on the basis of the time of the operation of the delivery pump 4 and the drain pump 6. Accordingly, the condensed water W is effectively discharged in a simple configuration.
  • the drain control unit upon starting of an initial operation of the dryer 100, is configured to drive the drain pump 6 for a third predetermined time regardless of the output of the first water level detection unit 31 and the output of the second water level detection unit 51.
  • the second water storage tank 5 empties the second water storage tank 5 to store a reasonable amount of condensed water W. Accordingly, both of the delivery pump 4 and the drain pump 6 are prevented from being driven due to the mismatch in a starting timing of the delivery pump 4 and the drain pump 6, thereby preventing the noise from occurring as both of the delivery pump 4 and the drain pump 6 are driven.
  • the dryer 100 in accordance with the first embodiment of the present disclosure, the condensed water W generated at the evaporator 13 is collected in the first water storage tank 3, which is installed at a lower side of the evaporator 13 and having a small size, by gravity without using a driving force.
  • the condensed water W is stored to the first predetermined water level in the first water storage tank 3, the condensed water W is delivered to the second water storage tank 5 by the delivery pump 4 having a small size and a small output to be added into a large amount, and the large amount of condensed water W is raised high to be discharged to an outside.
  • the condensed water W is not raised in small units, but is collected into a large amount in the second water storage tank 5 and is discharged, thereby reducing the number of operation times of the drain pump 6. Accordingly, the lifespan of the drain pump 6 is prevented from being decreased due to the frequent operation of the drain pump 6 while significantly reducing the noise of the drain pump 6 generated from the many of operation times of the drain pump 6.
  • the second water storage tank 5 has a large volume when compared to the first water storage tank 3, and has a capability to a large amount of condensed water W until the discharge, thereby significantly reducing the ratio of the volume of the condensed water W, which flows backward from a higher position to the second water storage tank 5 when the drain pump 6 is stopped, to the volume of the condensed water W, which is discharged at a single discharge, and also reducing the volume of the condensed water W making the dead volume.
  • the drain hose 7 has an end opening at a higher position when compared to the conventional cloth dryer, and the condensed water W is effectively discharged to an outside even in a case when the condensed water W is needed to be raised to a high position to be discharged.
  • the first water storage tank 3 is configured to be miniaturized so as to be installed at a small area suitable for collecting the condensed water W generated at the evaporator 13 while the second water storage tank 5 is configured to be as large as possible to store the condensed water W.
  • the first water storage tank 3 having a small size is installed. That is, the design flexibility of the first water storage tank 3 and the second water storage tank 5 are improved.
  • the delivery pump 4 may be driven at all times if the noise is small.
  • a drain mechanism of the dryer 100 in accordance with the second embodiment of the present disclosure has a first water storage tank 3 installed in a different manner from the first embodiment of the present disclosure.
  • the first water storage water tank 3 is integrally installed with a lower portion of the evaporator case 131, differently from the first embodiment of the present disclosure wherein the evaporator case 131 is separately installed from the first water storage tank 3.
  • the first water storage tank 3 is further miniaturized and the condensed water W is effectively collected.
  • the integral installation of the first water storage tank 3 eliminates the need to install a pipe connecting the evaporator case 131 to the first water storage tank 3 or to install a seal configured to prevent water leakage, thereby assuring a simpler structure.
  • a drain mechanism 200 of the dryer 100 in accordance with the third embodiment of the present disclosure is different from the first embodiment in a way that the delivery pump 4 is not installed, and by the use of the drain pump 5 only, the delivery from the first water storage tank 3 to the second water storage tank 5 and the discharge of the condensed water W to an outside are achieved.
  • the drain mechanism 200 is provided with a conversion mechanism to convert between a first state, in which the drain pump 6 is connected to the second water storage tank 5 and the drain hose, and a second state, in which the drain pump 6 is connected to the first water storage tank 3 and the second water storage tank 5.
  • the first water storage tank 3 is connected to the drain pump 6 and a lower portion of the second water storage tank 5 via a pipe through a first conversion valve 81 that is represented as a three-way valve.
  • the drain pump 6 is connected to the other end of the drain hose 7 and to an upper portion of the second water storage tank 5 via a pipe through a second conversion valve 82.
  • the drain control unit is configured to control the conversion of the connection of each member by controlling the direction of the first conversion valve 81 and the second conversion valve 82.

In addition, as shown in (b) of FIG. 4 , the drain control unit controls the second conversion valve 82 such that the drain pump 6 is communicated with the second water storage tank 5 while the pipe directed toward the drain hose 7 is closed. Thereafter, the drain control unit operates the drain pump 6.
