Description

Technical Field

[0001] The present invention relates to a clothes dryer.

Background Art

[0002] In recent years, in clothes dryers such as washing and drying machines, a configuration including a heat pump type drying device has become mainstream. In this drying device, a fan device, an evaporator and a condenser included in the heat pump device are arranged in a circulation path connected to a clothing storage section. In the drying process, air circulates between the storage section and the circulation path by the operation of the fan device, and the condenser becomes hot and the evaporator becomes cold by the operation of the heat pump device. The air heated by the condenser is supplied into the storage section and contacts the wet clothes. The air that has taken moisture from the clothes by contact returns into the circulation path, passes through the evaporator, and is cooled and dehumidified by the evaporator.

[0003] The less moisture there is in the air supplied into the storage section, the easier it is for the clothes in the storage section to dry, and the higher the drying efficiency of the clothes. However, the air circulating between the storage section and the circulation path has more moisture than the air outside the storage section and the circulation path even after being dehumidified. Therefore, it is conceivable to reduce the moisture of the circulating air and reduce the moisture of the air supplied into the storage section by exhausting a part of the air flowing in the circulation path to the outside and sucking in air with less moisture from the outside.

[0004] Patent Document 1 describes a clothes dryer in which, in an air circulation path for circulating drying air so as to guide it from an outer tub through a heat absorber (evaporator) and through a radiator (condenser) to the outer tub, an exhaust port is provided between the outer tub and the heat absorber, and a part of the drying air flowing through the air circulation path from the outer tub toward the heat absorber is discharged outside the air circulation path. An air intake for sucking in outside air is provided in the air circulation path between the outer tub and the exhaust port, and a blower fan is provided between the air intake and the exhaust port.

[0005] [Patent Document 1] Japanese Patent Publication No. 2005-318917 [Overview of the project] [Problems that the invention aims to solve]

[0006] In cases where an exhaust port is provided between the outer tub and the evaporator, as in the clothes dryer described in Patent Document 1 above, the highly humid air before dehumidification will be exhausted from the circulation path, which may cause the area around the clothes dryer to become humid and lead to a deterioration of the surrounding environment.

[0007] This invention has been made in view of the above problems, and aims to provide a clothes dryer that can improve the drying efficiency of clothes while minimizing deterioration of the surrounding environment. [Means for solving the problem]

[0008] A clothes dryer according to a main aspect of the present invention comprises a storage section for storing clothes, a circulation path connected to the storage section, a fan device disposed in the circulation path for circulating air in an air circulation path formed by the storage section and the circulation path, an evaporator disposed downstream of the fan device in the circulation path for cooling and dehumidifying the air flowing through the circulation path, a condenser disposed downstream of the evaporator in the circulation path for heating the air after it has been dehumidified by the evaporator, and an exhaust port provided between the evaporator and the condenser in the circulation path for discharging a portion of the air that has passed through the evaporator to the outside of the air circulation path.

[0009] According to the clothes dryer of this embodiment, since the air from which moisture has been reduced by dehumidification in the evaporator is discharged to the outside of the air circulation path through the exhaust port, even if this air spreads around the clothes dryer, the surrounding area is less likely to become hot and humid, and the surrounding environment is less likely to deteriorate.

[0010] In the clothes dryer according to this embodiment, a configuration may be adopted that further includes an air intake port provided in the air circulation path for taking in air from outside the air circulation path as air is discharged from the exhaust port, an opening provided in the storage section into which clothes are inserted, and a door that closes the opening. In this case, the air intake port may be provided in the storage section.

[0011] According to the above configuration, outside air is drawn into the air circulation path through the air intake and mixed with the air circulating within the air circulation path, thereby reducing the humidity of the circulating air. This reduces the humidity of the air supplied to the storage area, improving the drying efficiency of clothes. Furthermore, the air intake can also function as a vent, allowing air to enter and exit the storage area when the door is opened and closed. [Effects of the Invention]

[0012] According to the present invention, it is possible to provide a clothes dryer that can improve the drying efficiency of clothes while minimizing the deterioration of the surrounding environment.

[0013] The effects and significance of the present invention will become even clearer from the following description of embodiments. However, the following embodiments are merely examples of how the present invention can be implemented, and the present invention is not limited in any way to those described in the following embodiments. [Brief explanation of the drawing]

[0014] [Figure 1] Figure 1 is a schematic side cross-sectional view showing the configuration of a drum-type washing machine and dryer according to an embodiment. [Figure 2] Figure 2 is a perspective view showing the heat exchanger housing and introduction duct portion of a drying apparatus according to an embodiment. [Figure 3] Figure 3 is a longitudinal cross-sectional view of the heat exchanger housing and inlet duct cut at the location of the exhaust port, according to an embodiment. [Figure 4]Figure 4 is a diagram illustrating the airflow within the air circulation path during the drying process according to an embodiment. [Modes for carrying out the invention]

[0015] Figure 1 is a schematic side cross-sectional view showing the configuration of a drum-type washing machine and dryer 1.

[0016] The drum-type washer-dryer 1 comprises a rectangular box-shaped casing 10. A circular opening 11 into which laundry is loaded is formed on the front of the casing 10. The opening 11 is covered by a door 12 that can be opened and closed.

[0017] An outer tub 20 is placed inside the housing 10. The outer tub 20 is elastically supported by a plurality of dampers 21 and springs 22. Inside the outer tub 20, an inner tub, a drum 23, is rotatably positioned. The drum 23 rotates around a horizontal axis. The drum 23 has a circular opening 23a on its front. Laundry is put into the drum 23 through the input opening 11 and the opening 23a. The outer tub 20 and the drum 23 constitute a washing tub W in which clothes (laundry) are contained and washed and dried. The washing tub W corresponds to the "containment section" of the present invention.

[0018] The outer tub 20 has a substantially cylindrical opening 20a in front of the opening 23a of the drum 23, which is connected to the input port 11 by a water-sealing packing. Numerous dewatering holes 23b are formed in the circumferential wall of the drum 23. In addition, baffles 24 for scooping up laundry are provided in the circumferential wall inside the drum 23. The drum 23 may rotate around a rotation axis that is inclined with respect to the horizontal direction, provided it is a horizontal-axis type.

[0019] Behind the outer tub 20, a drive motor 30 that generates torque for rotating the drum 23 is arranged. The drive motor 30 is, for example, an outer rotor type DC brushless motor. During the washing process, rinsing process, and drying process, the drive motor 30 rotates the drum 23 at a rotational speed at which the centrifugal force applied to the laundry in the drum 23 is smaller than the gravitational force and the laundry tumbles. On the other hand, during the dehydration process, the drive motor 30 rotates the drum 23 at a rotational speed at which the centrifugal force applied to the laundry in the drum 23 is much larger than the gravitational force and the laundry sticks to the circumferential wall of the drum 23.

[0020] At the bottom of the outer tub 20, a drain port 20b is formed. A drain passage 40 composed of a drain hose or the like is connected to the drain port 20b. A drain valve 41 and a drain filter 42 are provided in the drain passage 40. The drain valve 41 includes, for example, a valve and a torque motor for opening and closing the valve.

[0021] When the drain valve 41 is opened, the water accumulated in the outer tub 20 is discharged outside the machine through the drain passage 40. The drain filter 42 captures foreign matters such as lint contained in the drain water.

[0022] At the upper part inside the housing 10, a water supply section 50 is arranged. The water supply section 50 includes a water supply valve 51 and a water supply passage 52. One end of the water supply passage 52 is connected to the water supply valve 51, and the other end is connected to a water injection port 20c provided on the back surface of the outer tub 20. When the water supply valve 51 is opened, tap water from a water tap flows through the water supply passage 52 and is supplied into the outer tub 20 from the water injection port 20c.

[0023] Note that the water supply section 50 may include an automatic dosing device for automatically dosing liquid detergent or liquid softener into the outer tub 20. The automatic dosing device includes, for example, a liquid agent tank for storing liquid detergent or liquid softener, and a pump for sending the liquid detergent or liquid softener in the liquid agent tank into the water supply passage 52. In this case, the liquid detergent or liquid softener discharged into the water supply passage 52 is sent into the outer tub 20 by the water flowing through the water supply passage 52.

[0024] An air intake port 25 is provided on the rear upper side of the outer tank 20. An air intake pipe 60 is connected to the air intake port 25. The air intake pipe 60 extends above the outer tank 20 and has an inlet 61 at a position higher than the outer tank 20.

[0025] A drying device 100 is located at the top of the housing 10 to dry the laundry in the drum 23 using heated air, i.e., hot air. The drying device 100 includes a circulation path 110, a fan device 120, a heat pump device 130, and a heater 140.

[0026] The circulation path 110 is an air passage through which air flows and is connected to the outer tank 20. The circulation path 110 includes an outlet duct 111, a fan casing 112, a heat exchanger housing 113, and an inlet duct 114. The circulation path 110 is located above the outer tank 20 within the housing 10.

[0027] The outlet duct 111 is connected at one end to an exhaust port 20d located on the rear of the outer tank 20, and at the other end to an intake port of the fan casing 112. The exhaust port 20d may be located at the rear of the circumferential surface of the outer tank 20.

[0028] The heat exchanger housing 113 has a box-like shape that is elongated in the front-to-back direction and is positioned above the outer tank 20, adjacent to the front of the fan casing 112. The rear end of the heat exchanger housing 113 is connected to the discharge port of the fan casing 112. The inlet duct 114 extends from the front end of the heat exchanger housing 113 and is connected to the inlet 20e formed in the front upper part of the outer tank 20.

[0029] The circulation path 110 is narrowed in the section of the introduction duct 114 downstream of the heat exchanger housing 113, resulting in a smaller flow area.

[0030] The fan device 120 is, for example, a centrifugal fan and includes a fan 121 housed in a fan casing 112 and a fan motor 122 for rotating the fan 121. The fan device 120 circulates air between the outer tank 20 and the circulation path 110. Air discharged from the outer tank 20 through the exhaust port 20d flows through the circulation path 110 in the order of the outlet duct 111, fan casing 112, heat exchanger housing 113, and inlet duct 114, and is introduced into the outer tank 20 through the inlet port 20e.

[0031] The heat pump device 130 includes an evaporator 131, a condenser 132, a compressor 133, a refrigerant circulation path 134, and a pressure reducer 135.

[0032] The evaporator 131 and the condenser 132 are positioned upstream and downstream of the airflow within the heat exchanger housing 113, respectively.

[0033] The compressor 133 compresses the refrigerant. The refrigerant circulation path 134 connects the evaporator 131 and condenser 132 to the compressor 133 and circulates the refrigerant. The pressure reducer 135, for example, is an expansion valve and is located between the evaporator 131 and condenser 132 in the refrigerant circulation path 134 to reduce the pressure of the refrigerant.

[0034] When compressor 133 operates, the refrigerant, compressed to high temperature and pressure, flows to condenser 132. Heat exchange with the high-temperature refrigerant flowing through condenser 132 heats the air flowing through circulation path 110. The refrigerant cooled by the air is depressurized through pressure reducer 135, becoming low temperature and low pressure, and flows to evaporator 131. Heat exchange with the low-temperature refrigerant flowing through evaporator 131 cools and dehumidifies the air flowing through circulation path 110. The refrigerant heated by the air returns to compressor 133.

[0035] The heater 140 is, for example, a semiconductor heater and is located within the heat exchanger housing 113, downstream of the condenser 132 in the airflow.

[0036] A drying filter 150 is positioned near the inlet of the heat exchanger housing 113 in the circulation path 110. The drying filter 150 captures foreign matter such as lint and dust contained in the air flowing through the circulation path 110. The drying filter 150 is detachable from the heat exchanger housing 113. An inlet / outlet 13 is formed on the top surface of the housing 10 at a position that overlaps vertically with the position of the drying filter 150 in the circulation path 110. The inlet / outlet 13 is closed by an openable / closable lid 14. When cleaning the drying filter 150, the user can open the lid 14 and remove the drying filter 150 from the circulation path 110 and take it out of the housing 10 through the inlet / outlet 13. Furthermore, the user can open the lid 14 and put the cleaned drying filter 150 back into the housing 10 through the inlet / outlet 13 and install it in the circulation path 110.

[0037] The circulation path 110 is provided with an exhaust port 115 located between the evaporator 131 and the condenser 132 in the heat exchanger housing 113.

[0038] Furthermore, the washing tub W and the circulation path 110 form an air circulation path CR through which air is circulated by the operation of the fan device 120.

[0039] Figure 2 is a perspective view showing the heat exchanger housing 113 and the introduction duct 114 in the drying apparatus 100. Figure 3 is a longitudinal cross-sectional view of the heat exchanger housing 113 and the introduction duct 114 cut at the location of the exhaust port 115.

[0040] As shown in Figure 2, the top surface 113a of the heat exchanger housing 113 is provided with three exhaust ports 115 arranged in the left-right direction. Each exhaust port 115 is composed of, for example, multiple elongated holes arranged in the front-to-back direction. The portion of the top surface 113a where the three exhaust ports 115 are provided is a sloping surface that descends toward the rear.

[0041] As shown in Figure 3, the evaporator 131 includes three heat exchangers 131a arranged in the front-to-back direction, i.e., in the direction of airflow. Each heat exchanger 131a is provided with numerous fins 131b. The condenser 132 includes three heat exchangers 132a arranged in the front-to-back direction. Each heat exchanger 132a is provided with numerous fins 132b.

[0042] Within the heat exchanger housing 113, the top surface 113a and bottom surface 113b are provided with four top ribs 113c and 113d extending in the left-right direction, respectively, in the upstream region where the evaporator 131 is located, spaced apart in the front-rear direction. Additionally, the top surface 113a and bottom surface 113b are provided with four top ribs 113e and 113f extending in the left-right direction, respectively, in the downstream region where the condenser 132 is located, spaced apart in the front-rear direction.

[0043] Each heat exchanger 131a of the evaporator 131 is positioned between the two front and rear top ribs 113c and between the two front and rear bottom ribs 113d. Similarly, each heat exchanger 132a of the condenser 132 is positioned between the two front and rear top ribs 113e and between the two front and rear bottom ribs 113f.

[0044] The three exhaust ports 115 are located on the top surface 113a of the heat exchanger housing 113, between the downstream (front row) top rib 113c and the upstream (rear row) top rib 113e. That is, the three exhaust ports 115 are sandwiched between the two top ribs 113c and 113e. The upstream top rib 113e protrudes lower than the downstream top rib 113c.

[0045] As shown in Figure 3, the drying filter 150 is positioned within the heat exchanger housing 113, upstream of the evaporator 131, and in close proximity to the evaporator 131. The drying filter 150 has a rectangular box shape that is flattened in the front-to-back direction. The drying filter 150 has openings 151 and 152 formed on its front and rear sides. A filter mesh 153 is attached to the opening 151 on the downstream side of the front side. Foreign matter such as lint contained in the air passing through the drying filter 150 is stopped by the filter mesh 153 and accumulates inside the drying filter 150.

[0046] An insertion opening 113g is formed in the top surface 113a of the heat exchanger housing 113. The drying filter 150 is inserted into the heat exchanger housing 113 through the insertion opening 113g and can be removed upward from the heat exchanger housing 113. A handle portion 154 is provided at the upper end of the drying filter 150 for gripping when attaching or detaching the drying filter 150.

[0047] As shown in Figure 3, the heater 140 is positioned within the heat exchanger housing 113, downstream of the condenser 132, and in close proximity to the condenser 132.

[0048] In the drum-type washer-dryer 1, various wash-and-dry cycles, wash cycles, and dry cycles are performed. In the wash-and-dry cycle, the washing, intermediate spin-drying, rinsing, final spin-drying, and drying cycles are performed in order. In the wash cycle, the washing cycle is performed up to the final spin-drying cycle, but the drying cycle is not performed. In the dry cycle, only the drying cycle is performed. Depending on the cycle, the rinsing and intermediate spin-drying cycles may be performed two or more times.

[0049] In the washing process, water containing detergent is filled into the outer tub 20 up to a washing water level corresponding to the load of laundry contained in the drum 23. The laundry immersed in this water tumbles inside the drum 23 as the drum 23 rotates repeatedly in the forward and reverse directions. The water containing detergent penetrates deep into the laundry, and the dirt is removed from the laundry by the combined force of the detergent and the mechanical force of tumbling.

[0050] During the rinsing process, the drum 23 rotates forward and backward with water filling the outer tub 20 up to the rinsing water level, causing the laundry to tumble around inside the drum 23. This allows the detergent contained in the laundry to be discharged along with the water, thus rinsing the laundry.

[0051] In the intermediate and final dewatering processes, the drive motor 30 rotates at high speed in one direction, causing the drum 23 to rotate in one direction at a speed at which the centrifugal force acting on the laundry inside the drum 23 is much greater than that of gravity. Due to the action of centrifugal force, the laundry is pressed against the circumferential walls of the drum 23 and dewatered.

[0052] During the drying process, the fan device 120 and the heat pump device 130 operate. As shown by the solid arrows in Figure 4, drying air circulates between the outer tub 20 and the circulation path 110, i.e., within the air circulation path CR. Furthermore, the drum 23 rotates in both forward and reverse directions, causing the laundry, i.e., the clothes, to tumble inside the drum 23.

[0053] Air heated by the condenser 132 is introduced into the outer tub 20, i.e., the washing tub W, through the inlet 20e, and comes into contact with the clothes inside the drum 23. The heated air removes moisture from the clothes, drying them out.

[0054] The air containing moisture removed from the clothes returns to the circulation path 110 through the exhaust port 20d, passes through the fan device 120, and reaches the evaporator 131. As the moisture-containing air passes through the evaporator 131, it is cooled and dehumidified by the evaporator 131. The dehumidified air is heated again in the condenser 132 and introduced into the washing tub W.

[0055] Within the heat exchanger housing 113, the internal pressure downstream of the evaporator 131 is higher than the atmospheric pressure outside the heat exchanger housing 113. Therefore, as shown by the dashed arrow in Figure 4, some of the air that has passed through the evaporator 131 is discharged from the exhaust port 115 to the outside of the heat exchanger housing 113, i.e., the air circulation path CR, without going to the condenser 132. The air discharged from the exhaust port 115 is dehumidified air, contains less moisture, and is at a lower temperature. Therefore, even if this air spreads outside the housing 10, i.e., around the drum-type washing machine 1, the surroundings are less likely to become hot and humid, and the surrounding environment is less likely to deteriorate.

[0056] As shown in Figure 3, the exhaust port 115 is located between two top ribs 113c and 113e. Therefore, some of the air is guided by the two top ribs 113c and 113e and flows smoothly to the exhaust port 115. In addition, the downstream top rib 113e protrudes downward more than the upstream top rib 113c, and some of the air hits the tip of the downstream top rib 113c, making it easier for the air to flow towards the exhaust port 115.

[0057] Furthermore, since the exhaust port 115 is located on the top surface 113a of the heat exchanger housing 113, even if the water condensed on the evaporator 131 due to dehumidification is blown away by the airflow (wind), it is less likely to reach the exhaust port 115 and less likely to be discharged from the exhaust port 115.

[0058] Furthermore, just before reaching the evaporator 131, foreign matter such as lint in the air is removed by the drying filter 150, thus preventing foreign matter from being discharged along with the air from the exhaust port 115.

[0059] As air is discharged from the exhaust port 115, as shown by the dashed arrow in Figure 4, outside air is drawn into the outer tub 20 through the intake port 25, i.e., into the air circulation path CR, and mixed with the air circulating within the air circulation path CR. The humidity of the circulating air is reduced, and as a result, the humidity of the air supplied to the washing tub W is reduced. This allows the air that comes into contact with the clothes to remove more moisture from the clothes, thus increasing the drying efficiency of the clothes.

[0060] In addition, during the drying process, the heater 140 may operate together with the heat pump device 130. In this case, the air supplied to the washing tub W becomes hotter than when only the heat pump device 130 is operating. Therefore, the heater 140 is operated, for example, when drying heat-resistant clothing.

[0061] When putting laundry, i.e., clothes, into or out of the drum 23, the door 12 is opened and closed. The air intake 25 is provided on the circumferential surface of the outer tub 20, i.e., the washing tub W, and also functions as a vent that allows air to enter and exit when the door 12 is opened and closed. That is, when the door 12 is closed, the air inside the outer tub 20 is discharged from the air intake 25, and when the door 12 is opened, outside air is drawn into the outer tub 20 from the air intake 25. This allows the door 12 to be opened and closed smoothly.

[0062] <Effects of the Embodiment> According to this embodiment, the drum-type washing and drying machine 1 includes a heat pump device 130 which includes a fan device 120 arranged in the circulation path 110 and circulating air in an air circulation path CR composed of the washing tub W and the circulation path 110, an evaporator 131 arranged downstream of the fan device 120 in the circulation path 110 and cooling and dehumidifying the air flowing in the circulation path 110, and a condenser 132 arranged downstream of the evaporator 131 in the circulation path 110 and heating the air after it has been dehumidified by the evaporator 131, and an exhaust port 115 provided between the evaporator 131 and the condenser 132 in the circulation path 110 and discharging a portion of the air that has passed through the evaporator 131 to the outside of the air circulation path CR.

[0063] With this configuration, the air from which moisture has been reduced by dehumidification in the evaporator 131 is discharged to the outside of the air circulation path CR through the exhaust port 115. Therefore, even if this air spreads around the drum-type washing machine 1, the surrounding area is less likely to become hot and humid, and the surrounding environment is less likely to deteriorate.

[0064] Furthermore, according to this embodiment, since an air intake port 25 is provided in the washing tub W to take in outside air from the air circulation path CR as air is discharged from the exhaust port 115, the air intake port 25 can function as a vent that allows air to be taken in and out of the washing tub W when the door 12 is opened and closed.

[0065] Although embodiments of the present invention have been described above, the present invention is not limited in any way by the above embodiments, and various modifications are possible to the embodiments of the present invention other than those described above.

[0066] For example, the air intake 25 may be provided not in the washing tub W, but in the circulation path 110, for example, in the outlet duct 111. In this case, it is preferable that the washing tub W be provided with a vent to allow air to enter and exit when the door 12 is opened and closed.

[0067] Furthermore, a door body such as a flapper that opens and closes the exhaust port 115, and an opening and closing device for opening and closing the door body may be provided. In this case, the exhaust port 115 may be opened during the drying process, once the clothes have dried to a certain extent, so that a portion of the air flowing through the air circulation path CR is discharged.

[0068] Furthermore, the exhaust ports 115 may be of any number, shape, and size as long as they can expel air. Also, the exhaust ports 115 may be located not on the top surface 113a of the heat exchanger housing 113, i.e., the top surface of the circulation path 110, but for example, on either the left or right side. Similarly, the intake ports 25 may be of any number, shape, and size as long as they can draw in air.

[0069] Furthermore, the drying apparatus 100 does not necessarily need to be equipped with a heater 140.

[0070] Furthermore, the configurations of the evaporator 131 and condenser 132 are not limited to those of the above embodiment, and may be any configuration.

[0071] Furthermore, the above embodiment illustrates a drum-type washing and drying machine 1 equipped with a horizontal-axis drum 23. However, the present invention can also be applied to a so-called vertical-type washing and drying machine, which has a vertical-axis washing and dewatering tub with a pulsator as an inner tub inside an outer tub. Furthermore, the present invention can also be applied to a clothes dryer that has only a drying function and no washing function. [Explanation of symbols]
