Description

  The present invention relates to a clothes dryer for drying textiles such as clothes and a clothes dryer having a washing function.

  A conventional clothes dryer of this type will be described with reference to FIGS. FIG. 7 is a longitudinal sectional view of a conventional clothes dryer, and FIG. 8 is a diagram showing a drying cycle. A rotating drum 103 that rotates with the clothes 102 placed inside the outer case 101 is disposed, and a clothes insertion port formed on the front surface of the rotating drum 103 is open to the front surface of the outer case 101 and is opened and closed by a door 104. . The inside of the rotary drum 103 is also a drying chamber 105, and constitutes an air circulation path 109 for circulating air in the order of the heat absorber 108, the drying chamber 105, and the radiator 107. The heat absorber 108 is arranged in a substantially vertical direction, and the heat radiator 107 is located on the leeward side of the heat absorber 108 and is attached substantially parallel to the heat absorber 108. Further, a partition plate 114 is provided between the heat absorber 108 and the heat radiator 107 substantially in parallel with the heat absorber 108 (see, for example, Patent Document 1).

  About the clothes dryer comprised as mentioned above, the operation | movement is demonstrated below. The heat absorber 108 and the heat radiator 107 constitute a heat pump cycle in which the refrigerant circulates together with the compressor 110, the throttle means 111 such as a capillary tube, and the like, and the gas refrigerant becomes a high temperature and high pressure state by driving the compressor 110. Flows into the radiator 107. By exchanging heat with the circulating air circulating in the air circulation path 109 by the radiator 107, the circulating air is heated, the refrigerant is cooled and condensed, and the phase changes to a high-pressure liquid refrigerant state. Next, the high-pressure liquid refrigerant is depressurized by the throttle means 111 and flows into the heat absorber 108 as a low-temperature low-pressure liquid refrigerant or a gas-liquid two-phase refrigerant. The heat absorber 108 exchanges heat with the high-humidity air coming from the drying chamber 105, the circulating air is cooled and dehumidified, and the refrigerant is heated to become a low-pressure gas refrigerant and reach the compressor 110.

  On the other hand, when the circulating air is cooled by the heat absorber 108 and the air is cooled below the dew point temperature, condensation is formed on the surface of the heat absorber 108 and the air is dehumidified. The air whose absolute humidity is reduced is heated by the radiator 107, becomes high-temperature and low-humidity air, is blown into the drying chamber 105 by the blower 106, and dries the clothes 102. Since the heating amount at this time is the sum of the heat exchange amount in the heat absorber 108 and the input of the compressor 110, the air temperature exiting from the air outlet 115 is higher than the air temperature flowing in from the air inlet 116. It becomes higher and the heating amount is more than the input of the compressor 110 that is the input of the device. At this time, dehumidified water dewed by the heat absorber 108 is dropped by gravity onto a drain pan 117 disposed below the heat absorber 108 and discharged from the drain port (not shown) to the outside of the apparatus.

JP 2005-304985 A

However, since part of the circulating air also flows into the drain pan 117, if the depth of the drain pan 117 is not sufficient, it is rolled up again before the dehumidified dehumidified water is drained, There is a possibility that the drying efficiency is lowered by scattering to the drying chamber 105 and the like. In a general clothes dryer, since the width of the air circulation path 109 is shorter than the length in the width direction of the heat exchanger such as the heat absorber 108 and the heat radiator 107, the width of the air outlet 115 and the air inlet 116. The circulating air velocity passing through the heat exchanger is higher and lower in the airflow direction, which is closer to the air outlet 115 which is the outlet of the box in which the heat exchanger is disposed, and the wind velocity is higher. The earlier one is more likely to roll up dehumidified water. For this reason, the drain pan 117 is provided with an inclination so that the dehumidified water is drained from the side near the air outlet 115 having a high circulating air speed to the side far from the air outlet 115, and even when a large amount of dehumidified water is generated, the dew condensation water is as much as possible. Suppression of winding is suppressed.

  However, the pressure difference is generated inside the drain pan 117 due to the difference in the flow velocity of the circulating air flowing directly above the drain pan 117, and is substantially orthogonal to the circulating air flow inside the drain pan 117 from the low flow velocity to the higher one. The flow of the dehumidifying water is naturally disturbed by the inclination of the drain pan 117, and the flow of the dehumidified water can be rolled up and scattered even if the depth of the drain pan 117 is sufficiently secured. . As a countermeasure, a space and a partition plate 114 are provided between the heat absorber 108 and the heat radiator 107 to prevent the heat radiator 107 from reaching the heat radiator 107 even if the dehumidified water is scattered. As a result, the size of the clothes dryer is increased, so that the spatial distance between the heat absorber 108 and the heat radiator 107 is limited.

  Accordingly, the present invention solves the above-described conventional problems, and provides a heat pump device that can smoothly drain dehumidified water, saves space, and has high drying efficiency. Is intended to provide.

  In order to solve the conventional problems, a clothes dryer of the present invention includes a compressor that compresses a refrigerant, a radiator that radiates heat of the compressed refrigerant into the air, and a pressure of the high-pressure refrigerant is reduced. A throttle part and a heat absorber that takes away heat in the air by the decompressed refrigerant, and form a refrigerant circulation line that returns from the compressor to the compressor through the radiator, the throttle part, and the heat absorber. A heat pump is arranged inside a box having an inlet and an outlet for circulating air to constitute a heat pump device, the circulating air heated by the radiator is discharged from the outlet of the box, and the clothes are stored in the drying The circulated air that has been blown into the room by a blower and deprived of moisture from the clothes is discharged out of the drying chamber, led from the entrance of the box to the heat absorber, and the circulated air dehumidified by the heat absorber is again released from the heat. Air circulation to the vessel In the clothes dryer comprising the above, the heat absorber has an inclination so as to drain dehumidified water in a direction substantially orthogonal to the direction of flow of the circulating air and away from the outlet of the box. And a drainage pan provided with a plate-like member that is substantially parallel to the flow direction of the circulating air.

  By arranging a plate-like member that is substantially parallel to the flow direction of the circulating air in the drain pan, the generation of an air flow that is substantially perpendicular to the circulating air flow generated inside the drain pan is suppressed, and the dehumidified water is smoothly drained. This makes it possible to prevent the dehumidified water from being rolled up and scattered, and thus can provide a clothes dryer equipped with a heat pump device with stable performance that does not reduce the drying efficiency. In addition, since the depth of the drain pan can be reduced, a clothes dryer having a thinner heat pump device can be realized.

  The clothes dryer of the present invention can smoothly drain dehumidified water, and can prevent the dehumidified water from splashing even when the drain pan depth is shallow, so it is thin and has stable performance that does not reduce drying efficiency. A heat pump device can be provided, and a clothes dryer that saves space while maintaining drying performance can be realized.

  A first invention includes a compressor that compresses a refrigerant, a radiator that radiates heat of the compressed refrigerant into the air, a throttle unit that depressurizes the pressure of the high-pressure refrigerant, and A box having a circulating air inlet and outlet, and a heat pump that forms a refrigerant circulation line from the compressor to the radiator through the heat sink, the throttle portion, and the heat absorber to return to the compressor. A heat pump device is arranged inside the body, the circulating air heated by the radiator is discharged from the outlet of the box, and blown by a blower into a drying chamber containing the clothes, thereby removing moisture from the clothes. In addition, an air circulation path is constructed in which the circulating air is discharged out of the drying chamber, led from the inlet of the box to the heat absorber, and the circulating air dehumidified by the heat absorber is again introduced into the radiator. In the clothes dryer Provided below the heat absorber is a drain pan which is inclined so as to drain dehumidified water in a direction substantially orthogonal to the direction of flow of the circulating air and away from the outlet of the box, Is a clothes dryer in which a plate-like member that is substantially parallel to the flow direction of the circulating air is disposed.

  With this configuration, by arranging a plate-like member that is substantially parallel to the flow direction of the circulating air in the drain pan, the occurrence of an air flow that is substantially perpendicular to the circulating air flow generated inside the drain pan is suppressed, and smooth. Since the dehumidified water can be drained and the dehumidified water can be prevented from being rolled up and scattered, a clothes dryer having a heat pump device with stable performance that does not reduce the drying efficiency can be provided. In addition, since the depth of the drain pan can be reduced, a clothes dryer having a thinner heat pump device can be realized.

  In the second invention, in particular, the drain pan of the first invention is configured integrally with the bottom surface of the box of the heat pump device, and the drain pan is integrated with the box of the heat pump device. The height of the device can be shortened.

  In the third aspect of the invention, in particular, the drainage path on the drainage pan of the first or second invention is configured to have a meandering shape by the plurality of plate-like members, and the circulating air flow generated inside the drainage pan Therefore, the dehumidified water can be drained more smoothly and the dehumidified water can be prevented from being rolled up and scattered.

  According to the fourth aspect of the invention, in particular, a drain pan is also formed in the lower part of the radiator of any one of the first to third aspects, and a plate-like member is disposed also in the drain pan. Circulating air contains lint waste generated from dry clothing, and even if a lint filter is disposed in the circulation path, fine lint waste cannot be captured and adheres to the surface of the heat absorber. When such lint waste reaches the drain pan with dripping of dehumidified water and accumulates, a part of the dehumidified water is rolled up in the case of poor drainage caused by accumulation, or when the clothes dryer body is tilted and installed in the radiator. There is a possibility of scattering. However, a drain pan similar to the above is also formed in the lower part of the radiator, and a plate-like member is disposed so that the dehumidified water is surely drained up to the radiator and does not reach the drying chamber. Can be minimized.

In the fifth invention, in particular, the heat pump device according to any one of the first to fourth inventions is configured above the drying chamber. In clothes dryers that are assumed to be installed on the floor, the drying chamber is generally located above the entire clothing dryer in consideration of the ease of taking out clothes. There is no margin in the direction. However, since the clothes dryer of the present invention has a structure capable of sufficiently draining even if the depth and inclination angle of the drain pan is shallow, it can be disposed above the drying chamber by reducing the thickness of the heat pump device. As a result, when the heat pump device is disposed below the clothes dryer, a separate pump or the like may be required for draining dehumidified water, but drainage is possible only with natural drainage due to the difference in height. In addition, the air circulation path length is shortened, heat loss is reduced, and drying efficiency is increased.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. Note that the present invention is not limited to the embodiments.

(Embodiment 1)
1 is a cross-sectional view of a clothes dryer according to Embodiment 1 of the present invention, FIG. 2 is a view showing a drying cycle system of the clothes dryer, and FIG. 3 is a horizontal cross-sectional view of the vicinity of the heat pump device of the clothes dryer. .

  1 to 3, the outer tub 1 is elastically supported by a plurality of suspension mechanisms 3 inside a housing 2 of a clothes dryer. The drum 4 is a drying chamber in which the clothes 5 are accommodated and dried. The drum 4 has a drum insertion port 6 through which the clothes 5 are taken in and out on the front side, is configured in a bottomed cylindrical shape, and is disposed in the outer tub 1. . The drum 4 is rotatably provided by a drum rotating shaft 11, a plurality of discharge holes 8 are provided in the peripheral wall 7 of the drum 4, and a stirring baffle for efficiently lifting the clothes 5 on the peripheral wall 7 in the drum 4. 9 is provided. The outer tub 1, the drum 4, and the drum rotation shaft 11 are disposed to be inclined upward by an angle θ (for example, 20 °) with respect to the horizontal.

  A driving unit 10 is provided outside the outer tub 1 to rotate the drum 4 forward and backward. On the front surface of the housing 2, there are provided a substantially circular insertion port 6 a that is provided in correspondence with the drum insertion port 6 and puts in and out the clothing 5, and a door 12 that opens and closes this. The opening of the outer tub 1 facing the inlet 6a is connected to the housing 2 by a packing 13 while ensuring an airtight structure.

  An air circulation path 14 including the outer tub 1 and the drum 4 is configured at a substantially upper portion of the outer tub 1. In the air circulation path 14, the circulating air discharged from the drum 4 through the outlet 15 of the outer tub 1 passes through the lint filter 16, the heat absorber 17, the radiator 18, and the blower 19 in this order, and sucks the outer tub 1. It is configured to circulate again into the drum 4 through the mouth 20. The lint filter 16 captures lint such as lint and lint contained in the circulating air generated from the garment 5, thereby preventing problems caused by lint accumulation in the heat absorber 17, the heat radiator 18, and the blower 19. It is provided so as to be removable from the clothes dryer main body. The blower 19 includes a fan motor 19a that drives the blower 19 and a motor current measuring device 19b that measures the current value of the fan motor 19a.

  The heat absorber 17 and the heat radiator 18 are heat exchangers including a pipe through which the refrigerant flows and fins that promote heat exchange. The compressor 21 compresses the refrigerant, the throttle unit 22 depressurizes the high-pressure refrigerant, and removes foreign matter in the refrigerant. A heat pump device 24 is configured in a casing 32 that is a box together with a strainer 23 for separation. Further, in order to detect the refrigerant temperature in the compressor 21, a temperature detection unit 21 a that detects the refrigerant temperature is disposed in a pipe immediately after the compressor 21.

  In order to make the heat pump device 24 as small as possible, as shown in FIG. 3, the air inlet 24a, the heat absorber 17, the radiator 18, and the air outlet 24b are arranged in this order. The compressor 21, the throttle unit 22, and the strainer 23 are all disposed on either the left or right side of the outside of the air path of the vessel 17. At this time, a region in which the pipes including the throttle unit 22 and the strainer 23 are collectively arranged without waste is referred to as a storage unit 25. In order to efficiently connect the blower 19 and the heat pump device 24 in a space-saving manner, an air outlet 24 b is provided adjacent to the housing portion 25 that houses the compressor 21 and the like, and is connected to the blower 19.

By disposing the blower 19 on the side of the compressor 21 by arranging in this way, the heat pump device 24 can be reduced in size, and the air outlet 24b can be positioned corresponding to the heat absorber 17 and the radiator 18. In the air circulation path 14, the dehumidified water is prevented from being rolled up or scattered in cooperation with the inclined direction of the drain pan 28 by being moved to one side from the center in the width direction.

  The high-temperature and high-humidity circulating air from the drum 4 is dehumidified and absorbed by the heat absorber 17 and then heated by the radiator 18 to be supplied into the drum 4 as high-temperature drying circulating air, thereby drying the clothes 5. At this time, the thermal energy released from the radiator 18 to the circulating air is approximately equal to the sum of the amount of power consumed by the compressor 21 and the amount of heat absorbed from the heat absorber 17. Therefore, an output higher than the power input to the compressor 21 is obtained from the radiator 18, and the garment 5 can be dried with low power consumption.

  However, if the circulating air is continuously circulated through the air circulation path 14, the amount of heat of the circulating air gradually increases by the amount input to the compressor 21, and the amount of heat of the refrigerant in the heat pump device 24 increases accordingly. Since the pressure also increases, the compressor 21 is finally overloaded. For this reason, the heat pump device 24 cannot operate stably, and the output of the compressor 21 must be reduced, resulting in a reduction in drying efficiency. Therefore, an exhaust port 26 that exhausts a part of the circulating air and an intake port 27 that supplements the exhausted circulating air and sucks the outside air are provided after the outlet 15 of the outer tub 1.

  On the other hand, when the high-temperature and high-humidity circulating air is cooled to the dew point temperature or lower by the heat absorber 17, dew condensation occurs on the surface of the heat absorber 17 and the air is dehumidified. The dehumidified water dewed by the heat absorber 17 is dropped by gravity onto a drain pan 28 formed integrally with the bottom surface of the casing 32 of the heat pump device 24 in the downward direction of the heat absorber 17.

  The configuration of the drain pan 28 will be described with reference to FIGS. 4 is a top view in the vicinity of the drain pan 28 (the heat absorber 17 and the radiator 18 are respectively indicated by broken lines), and FIG. 5 is a longitudinal sectional view in the vicinity of the drain pan 28. The drain pan 28 is inclined so as to be lowered toward the housing portion 25, and a plurality of plate-like members 29 that are substantially parallel to the flow direction of the circulating air are arranged in a meandering manner. On the side of the accommodating portion 25, in addition to the throttle portion 22 and the compressor 21, a drain port 30 for draining dehumidified water generated in the heat absorber 17 is also configured along the bottom surface of the casing 32, and is accommodated from the drain pan 28. A slope and a rib are provided to guide dehumidified water that is naturally drained to the portion 25 to the drain port 30.

  The meandering arrangement of the plate member 29 will be described. As shown in FIG. 4, two wall portions 31 a and 31 b that are parallel to each other in a direction substantially orthogonal to the flow direction of the circulating air are erected upward on the inner bottom surface of the drain pan 28. From the side surface of the wall 31a, a plurality of plate-like members 29a are provided at substantially equal intervals in the downstream direction of the flow of the circulating air. A plurality of plate-like members 29b are provided at substantially equal intervals from the side surface of the wall portion 31b toward the upstream direction of the flow of the circulating air. And the meandering arrangement | positioning of the plate-shaped member 29 is comprised by arrange | positioning so that the plate-shaped member 29a and the plate-shaped member 29b may be inserted alternately.

  The control unit (not shown) controls the drive unit 10, the blower 19, the compressor 21, and the like, controls the drying operation, and also detects the detected value from the temperature detection unit 21a and the current measured by the motor current measuring device 19b. A value or the like is input. The control unit also has an air volume detection unit (not shown) that detects the air volume of the circulating air from the current value measured by the motor current measuring device 19b.

  1 to 3 indicate the flow of the circulating air, and arrow B in FIG. 2 indicates the flow of the refrigerant flowing through the pipe of the heat pump device 24.

About the clothes dryer comprised as mentioned above, the operation | movement and an effect | action are demonstrated below.
In the drying process, the drum 4 rotates while holding the wet clothes 5 at the beginning of operation. The circulating air heated by the radiator 18 is blown by the blower 19 and arrives inside the drum 4 from the suction port 20. The circulating air arriving at the drum 4 comes into contact with the wet clothing 5 and deprives the moisture of the clothing 5, and then exits the drum 4 while containing lint generated from the clothing 5, from the outlet 15 provided in the outer tub 1. Exit the outer tank 1. The circulating air exiting the outer tub 1 is dehydrated by the heat absorber 17 after the lint is removed by the lint filter 16 and reaches the radiator 18 again. The dehumidified water that has condensed on the surface of the heat absorber 17 is dropped by gravity onto a drain pan 28 that is disposed below the heat absorber 17.

  Since the width of the air outlet 24b is shorter than the length in the width direction of the heat exchanger such as the heat absorber 17 or the radiator 18, the circulating air speed passing through the heat absorber 17 or the radiator 18 is reduced to the air outlet 24b. A speed difference occurs such that the closer one is faster and the farther one is slower, and the higher the wind speed, the more easily the dehumidifying water is rolled up. However, in this configuration, the drain pan 28 is configured to have a downward slope toward the accommodating portion 25 away from the air outlet 24b. Therefore, dehumidified water is reduced at a place where the circulating air speed is relatively fast, and the circulating air is reduced. This makes it difficult to roll up dehumidified water.

  Further, a pressure difference is generated inside the drain pan 28 due to the difference in speed of the circulating air (arrow A) flowing directly above the drain pan 28, and the inside of the drain pan 28 is directed from the low flow velocity to the high flow velocity of the circulating air. An air flow substantially perpendicular to the circulating air flow that causes the inclination of the drain pan 28 to flow backward in the high direction is generated, and the inclination of the drain pan 28 may impede the flow of dehumidified water that is naturally drained. However, since the plate-like member 29 is disposed in the drain pan 28 substantially in parallel with the flow direction of the circulating air, the dehumidified water is smoothly drained in order to suppress the generation of an air flow that flows backward in the above inclination. Since it is possible to prevent the dehumidifying water from being rolled up and scattered, it is possible to provide the heat pump device 24 having a stable performance in which the drying efficiency does not decrease.

  In addition, since it is configured to suppress the generation of air flow, which is a cause of dehumidification water winding up and scattering, it is possible to sufficiently discharge dehumidified water even when the depth of the drain pan 28 is shallow or the inclination angle is shallow. Thus, a thinner heat pump device 24 can be realized while maintaining the drying efficiency. Therefore, after the drum 4 and the inlet 6a of the clothes 5 are configured above the clothes dryer, the heat pump device 24 can be configured in a limited area above them. As a result, when the heat pump device 24 is disposed below the clothes dryer, a separate pump or the like may be required for draining the dehumidified water, but it can be drained only by natural drainage due to the height difference. . In addition, the circulation path length is shortened, heat loss is reduced, and drying efficiency is increased.

  In addition, since the plate-like member 29 has a meandering shape, the flow of air substantially orthogonal to the circulating air flow that reverses the inclination generated inside the drain pan 28 can be greatly suppressed. And can prevent scattering. At this time, the optimum value of the interval between the plate-like members 29 is the material and surface wettability of the drain pan 28 and the plate-like member 29, the flow rate of circulating air, the depth and inclination of the drain pan 28, and the drying rate (dehumidified water generation rate ), Etc., but if the interval is too short, drainage will be poor, so it is better to secure an interval of at least 8 to 10 mm.

  In the present embodiment, the plate-like member 29 is formed in a meandering shape on the lower side of the heat absorber 17, but is not limited thereto, and may be configured on the lower side of the radiator 18. . The circulating air contains lint waste generated from the dried clothes 5, and even if the lint filter 16 is disposed in the circulation path, the fine lint waste cannot be captured and adheres to the surface of the heat absorber 17. When such lint waste flows into the drain pan 28 together with dehumidified water and accumulates, or when the clothes dryer itself is tilted, a part of the dehumidified water is rolled up, 18 may be scattered. Even in such a case, a drain pan 28 similar to that described above is formed at the lower portion of the radiator 18 and the plate-like member 29 is disposed, so that the dehumidified water is reliably discharged, and the dehumidified water is contained in the drum 4. Since the clothes 5 are not reached, the deterioration of the drying performance can be minimized.

(Embodiment 2)
FIG. 6 is a top view of drain pan 28 of the clothes dryer according to Embodiment 2 of the present invention (heat absorber 17 is indicated by a broken line). Since the basic configuration is the same as that of the first embodiment, the description is omitted, and different points will be mainly described. The same components as those in the first embodiment are denoted by the same reference numerals.

A plurality of the plate-like members 29 are arranged in the same manner as in the first embodiment, but are alternately arranged at an angle α toward the downward inclination direction of the drain pan 28.
Therefore, since the plate-like member 29 is configured to be inclined in the inclination direction of the drain pan 28 while suppressing the flow of air substantially orthogonal to the circulating air flow that reverses the inclination of the drain pan 28, the dehumidified water is also It can be drained more naturally, and can further prevent the dehumidifying water from being rolled up.

  As described above, since the clothes dryer according to the present invention is configured to stably operate the heat pump device and efficiently perform the drying operation while saving space, the clothes dryer has a drying function as well as a clothes dryer. It is also useful as a machine.
