Description

  The present invention relates to a clothes dryer for drying clothes and the like.

  Conventionally, this type of clothes dryer is provided with a drying filter that captures lint from the clothes during the drying operation. Since lint is gradually trapped and accumulated in the drying filter during the drying process, clogging occurs and the air volume decreases, so it is considered that the lint captured by the drying filter is washed away with water (for example, Patent Documents). 1).

  FIG. 8 shows a conventional washing and drying machine described in Patent Document 1. In FIG. In FIG. 8, a water tank 52 is elastically supported in a casing 51, and a cylindrical rotating tank 53 is rotatably provided in the water tank 52. The rotating tank 53 is rotationally driven by a motor 54 attached to the outside of the rear surface of the water tank 52. A large number of holes 55 are provided in the peripheral side surface of the rotating tub 53 to communicate with the water tank 52. The rotating tub 53 functions as a laundry room during washing and functions as a drying room during drying. Wash water in the water tank 52 passes through a drain pipe 57 from a drain port 56 provided at the bottom, is discharged through a drain valve 58 and a drain filter 59, and reaches a drain trap 60 outside the machine.

  A blower 61 is disposed in the lower part of the casing 51, and drying air is blown into the rotary tank 53 from the blower opening 63 provided in the front part of the water tank 52 through the circulation air passage 62 during the drying operation. In the circulation air passage 62, an evaporator 64 and a condenser 65 of a heat pump device are arranged, and the drying air that has been wetted by contact with clothes flows out of the rotary tank 53 and enters the circulation air passage 62 to evaporate. After being cooled and dehumidified by the cooler 64, it is heated by the condenser 65, and becomes high-temperature dry drying air that circulates to the rotary tank 53.

  During the drying operation, lint generated from clothes and the like is blown together with the drying air and adheres to and accumulates on the blowing means 61 provided in the circulation air passage 62, causing the function to deteriorate. A drying filter 66 that captures the air is provided in the circulation air passage 62 and is disposed on the windward side of the air blowing means 61.

  As the drying operation proceeds, lint accumulates on the dry filter 66 and the circulating air flow decreases, so water is poured from the water injection pipe 67 along the surface of the dry filter 66 to wash away the captured lint. The washing of the lint is performed after the drying operation is completed, and the washed-off water and lint are discharged from the drain pipe 57 through the drain path 68 and the drain valve 58 to the outside of the machine.

  However, the conventional configuration has a problem that the lint washed away from the dry filter by pouring water from the water pouring pipe is easily clogged by the drainage path including the drainage pipe and the drainage path. The drainage path is provided with a lint filter included in the laundry drainage and a drainage filter that captures the lint washed away from the dry filter. The lint captured by the drainage filter is discarded by removing the drainage filter from the drainage path. The drainage path is provided with a drainage valve on the upstream side of the drainage filter. The drainage valve opens and closes according to the drainage operation, and prevents water leakage from the drainage path when the drainage filter is removed. The lint flowing through the drainage path is easily clogged by the drainage valve that opens and closes the drainage path, which hinders the operation of the drainage valve and makes the drainage path open and close uncertain.

  In particular, the lint trapped by the dry filter is pressed against the filter surface by the circulating dry air during the drying operation and collects and accumulates in a film form. Lint deposited on the drying filter is generally removed after the drying operation. Since the lint after the drying operation is fixed to the filter surface in a dry state, it is difficult to disperse and flow the lint attached to the filter surface by water injection. It is necessary to pour water vigorously. When lint separated from the filter surface in a lump, the drainage path was clogged with lint. Moreover, in order to prevent clogging of the drainage path by the detached lint, there is a problem that the amount of water when flowing the lint increases.

  SUMMARY OF THE INVENTION The present invention solves the above-described conventional problems, and an object thereof is to provide a clothes dryer that can prevent clogging of a drainage path due to lint removed from a dry filter device.

  In order to solve the conventional problems, a clothes dryer of the present invention includes a dry filter device that captures lint contained in drying air, and a lint that removes lint captured by the dry filter device from the dry filter device. A removing unit; and a lint crushing unit that crushes the lint removed by the lint removing unit.

  Thereby, the lint removed from the dry filter device can be crushed and flowed, and clogging of the drainage path by lint can be prevented.

  The clothes dryer of the present invention can prevent the drainage path from being clogged by the lint removed from the drying filter device.

  The control means 46 is disposed at the lower front part in the housing 2, and includes a motor 10, a washing water supply valve 13, a washing drain valve 17, a blowing means 26, a heat pump device 27, a lint removing means driving motor 39, a water supply valve 42c, The cutter driving motor 43b and the like are controlled to sequentially control each of the steps of washing, rinsing, dewatering and drying.

  The output of the pressure detection means (not shown) for detecting the pressure in the water tank 1 and the water level of the washing water, the motor rotation speed detection means 47 for detecting the rotation speed of the motor 10, and the temperature of the refrigerant flowing through the radiator 29 are as follows. The output of the refrigerant temperature detecting means 48 to be detected is input.

  The operation and action of the washing / drying machine configured as described above will be described below. By inputting the selection of the driving course and the time of each process from the operation display unit 49 provided at the upper front of the housing 2, the control means 46 performs a series of operations from washing to drying based on the set content. It is possible to carry out, and it is also optionally possible to carry out only the drying step.

  When washing is performed, the door body 11 is opened, the laundry 5 is put into the rotating tub 4, and an operation course or the like is input from the operation display unit 49 to start the operation. Water and detergent are supplied inside, and the rotating tub 4 is driven to rotate by the motor 10 to start the washing process.

  When the rotating tub 4 rotates at a predetermined speed, the laundry 5 is lifted in the rotating direction by the stirring baffles 9 provided at a plurality of locations on the inner peripheral surface, and is tapped by dropping from above in the rotating tub 4. Washing is performed by repeating the washing for a predetermined time.

  After the washing process, the rinsing process and the dehydrating process are executed to complete the washing. When an operation course that consistently executes from the washing process to the drying process is selected and input, when the washing process is completed, the control means 46 executes the drying process following the washing process. Moreover, when drying wet clothes etc., only a drying process can be performed.

  In the drying process, when the laundry 5 or wet clothing (hereinafter referred to as clothing) that has been dehydrated is stored in the rotating tub 4 and the drying process is executed, the rotating tub 4 is rotated at the rotation speed set in the drying process. , The air blowing means 26 and the heat pump device 27 are driven, and the air circulation of the drying air into the rotating tub 4 is started. In this drying process, the water tank 1 plays the same role as a drying chamber in a clothes dryer.

  In the heat pump device 27, the refrigerant is compressed by the operation of the compressor 28, and by this pressure, the refrigerant flows through the pipe line 32 from the compressor 28 and circulates through the radiator 29, the throttle means 30, the heat absorber 31, and the compressor 28. Since the heat of the compressed refrigerant flows into the radiator 29, it is radiated to the air in contact with the fins provided in the pipe line 32 provided in the radiator 29, so that the drying refrigerant flowing in the circulation air passage 21 is used. Air is heated.

  The heated drying air is supplied to the rotating tub 4 from the air blowing port 20, takes moisture from the laundry 5 or clothes, becomes moist air, and is discharged from the discharge port 19 to the circulation air passage 21. Lint L such as lint is generated from clothes as the clothes are dried. The drying air discharged from the discharge port 19 is introduced from the introduction unit 35 into the drying filter device 25, and the mesh of the filter unit 37 captures the lint L.

  The drying air from which the lint L has been removed by the drying filter device 25 is dehumidified when sensible heat and latent heat are taken away when passing through the heat absorber 31 through which the refrigerant that has been depressurized by the throttling means 30 flows to a low pressure. Condensed water generated by dehumidification is dropped into a water storage unit (not shown), and the dehumidified and dried drying air passes through the radiator 29 and is heated. The dehumidified condensed water is drained outside the machine through the washing drainage path 16.

  The amount of heat by which the drying air is heated by the radiator 29 is substantially equal to the sum of the power consumption of the compressor 28 and the amount of heat absorbed from the drying air by the heat absorber 31. It is possible to heat the drying air by obtaining an output that is equal to or higher than the power input to. However, if the drying air in the circulation air passage 21 is repeatedly circulated, the amount of heat of the entire drying air will continue to be accumulated by subtracting the amount of heat radiated naturally from the amount corresponding to the power consumption of the compressor 28. Become.

  At the same time, the amount of heat of the refrigerant in the heat pump device 27 continues to increase, the temperature and pressure of the refrigerant rise, and there is a possibility that an overload will be applied to the compressor 28 before long. In order to avoid this, an exhaust port 33 for exhausting a part of the drying air flowing through the circulation air passage 21 to the outside of the circulation air passage 21 and an intake port 34 for introducing outside air into the circulation air passage 21 are provided. Yes.

  In order to reduce the amount of heat possessed by the refrigerant, the control means 46 opens the intake valve 34 a provided at the intake port 34 based on the output of the refrigerant temperature detection means 48 to introduce outside air into the circulation air passage 21, and the exhaust port 33. A part of the drying air flowing through the circulation air passage 21 is exhausted to the outside of the circulation air passage 21 by opening the exhaust valve 33 a provided in the air.

  Circulation air is introduced by the introduction of the outside air into the circulation air passage 21, the cooling of the outside air flowing into the circulation air passage 21 by the partial exhaust of the drying air flowing through the circulation air passage 21, and the exhaust of the high-temperature drying air. Since the temperature of the drying air flowing through the passage 21 is lowered, the temperature of the refrigerant is also lowered, and the compressor 28 is prevented from being overloaded due to the excessive rise in the refrigerant temperature.

  When the refrigerant temperature is lowered to a predetermined temperature, the intake valve 34a and the exhaust valve 33a are closed, the introduction of outside air from the intake port 34 and the exhaust from the exhaust port 33 are eliminated, and the air blown into the circulation air passage 21 is dried. The amount of heat is accumulated in the working air, and drying air with a high drying effect circulates.

  The amount of lint L generated from the laundry 5 such as clothes increases from the start of drying when the clothes are wet, and the amount of lint L generated increases as the drying of the clothes progresses. Will increase.

  When the drying process is performed in a state where the lint L is accumulated on the drying filter device 25, the drying air circulating in the circulation air passage 21 is less likely to flow from the drying filter device 25 to the downstream side, and the drying performance is reduced. The control means 46 removes the lint L accumulated on the dry filter device 25 after the drying operation, for example.

  Specifically, the lint removing unit 38 has a spiral shape inscribed along the filter unit 37, and the control unit 46 drives the lint removing unit drive motor 39 to rotate the lint removing unit 38.

  When the lint removing means 38 scrapes the lint L, the lint L on the mesh is applied with forces in the radial direction and the thrust direction of the mesh. Because of these forces, the lint L moves in the direction Z along the rotation axis of the lint removing means 38 while being scraped off, so that even if the lint L scraped off is fine, it is transferred to the lint crushing means 40. And can be transported.

  While the lint removing unit 38 is being driven, the control unit 46 opens the water supply valve 42c and injects water from the nozzle portion 42a. The lint L transferred to the end of the lint removing unit 38, that is, the outlet 37a of the filter unit 37 absorbs the water sprayed from the nozzle unit 42a, increases its mass, falls to the lint crushing unit 40, and falls into the lint. Housed in the storage room 41. The water sprayed from the nozzle part 42 a is also absorbed by the lint L accommodated in the lint accommodating chamber 41.

  Further, after the lint removing unit 38 is driven for a predetermined time, the control unit 46 drives the cutter driving motor 43b and rotates the rotary blade 43a to finely pulverize the lint L. The pulverized lint L passes through the washing drainage path 16 from the discharge part 44 through the discharge path 45 by the water sprayed from the nozzle part 42a, and is discharged outside the machine. The discharge part 44 provided in the lower part of the lint storage chamber 41 is configured to allow the lint L finely pulverized to a predetermined size to pass therethrough.

  In the present embodiment, since the lint L can be removed from the filter unit 37 without spraying water onto the filter unit 37, the lint can be used even during the driving of the blowing unit 26, for example, during the drying operation. L can be transferred to the lint crushing means 40 by the lint removing means 38, and the drying air can be passed smoothly without the lint L being deposited in a large amount on the filter unit 37.

  As described above, in the present embodiment, the rotating tank 4 that is rotatably provided in the housing 2, the motor 10 that rotationally drives the rotating tank 4, and the circulation that introduces drying air into the rotating tank 4. An air passage 21, an air blowing means 26 for blowing air to the circulation air passage 21, a dehumidifying means 31 for dehumidifying drying air that has come out of the rotating tank 4, and a heating means 29 for heating the drying air dehumidified by the dehumidifying means 31; The dry filter device 25 that captures lint contained in the drying air, the lint removing means 38 that removes the lint captured by the dry filter device 25 from the dry filter device 25, and the lint removed by the lint removing means 38 is crushed. The lint crushing means 40 is provided, the lint removed from the dry filter device 25 can be crushed and flowed, and the drainage path can be prevented from being clogged by lint. In addition, by pulverizing the lint, water flowing through the lint can be reduced.

  In the present embodiment, since the heat radiator 29 of the heat pump device 27 is used as a heating unit and the heat absorber 31 is used as a dehumidifying unit, a predetermined drying performance can be obtained at a low temperature and with a small amount of power consumption. . In addition, a heating means may be comprised with a heater and a dehumidification means may be comprised with a water-cooling type heat exchanger.

  In this embodiment, the washing / drying machine having a washing function is used. However, even in a clothes drying machine having no washing function, the same effect can be obtained with respect to the performance of discharging lint and the performance of the heat pump device. can get.

  In the present embodiment, the electric cutter 43 is used as the lint crushing means 40. For example, a configuration in which a jet flow collides with the lint L and crushes with a water flow (not shown), or a shredder is used. Thus, a configuration (not shown) in which the lint L is finely cut by a plurality of blades may be used.

In order to discharge lint, the control means 46 first opens the water supply valve 42c to supply water from the nozzle part 42a to the lint storage chamber 41 and store the water in the water storage part 40c.

  Water whose water level W in the water storage section 40c exceeds the height h1 of the water seal section 40b is discharged from the drainage section 40a and flows into the discharge path 45. In the meantime, the control means 46 drives the lint removal means drive motor 39 to rotate the lint removal means 38 and scrapes the lint L of the filter portion 37 with the spiral shaped part of the lint removal means 38.

To increase. The lint L immersed in the water accumulated in the water storage unit 40c is finely pulverized by the electric cutter 43 of the lint crushing means 40 and dispersed in the water storage unit 40c.
