Next, a description will be given of a specific embodiment of the present invention with reference to the drawings.
The following description will be made of a washing and drying machine having both a washing function and a drying function as an example of a drum-type laundry treatment apparatus according to the present invention. Those skilled in the art can understand that the drum type laundry treating apparatus of the present invention may also be a dryer having only a drying function.
As shown in fig. 1 to 2, the drum-type laundry treating apparatus 1 includes: a housing 10; an outer tub 20 supported in the housing 10; a drum 30 rotatably installed in the outer tub 20 for receiving laundry; and a heat pump device 40 for drying the laundry in the drum 30 using the heated air. For convenience of explanation, the front-back direction, the left-right direction, and the up-down direction are defined as shown in fig. 1, and these directions are used in the following drawings.
As shown in fig. 1, the casing 10 constitutes a substantially rectangular parallelepiped outer shape of the drum-type laundry treatment device 1, and includes a left wall plate 11, a right wall plate 12, a front wall plate (not shown), a rear wall plate 13, and a top wall plate (not shown) formed of a plate material such as a metal plate or a resin plate. In order to facilitate the observation of the structure inside the housing 10, the top wall plate and the front wall plate are not shown in fig. 1 to 3 and 9, and the respective wall plates are not shown in fig. 13.
As shown in fig. 1 to 2, the outer tub 20 has a bottomed cylindrical shape having a laundry inlet 21 at one end. The outer tub 20 is mounted in the housing 10 with the laundry inlet 21 facing forward, and is elastically supported by the housing 10 by the lower damper 22 and the upper suspension spring 23, thereby preventing vibration of the outer tub 20 from being transmitted to the housing 10. Further, although not shown, a door for opening and closing the laundry inlet 21 is attached to a front wall plate of the casing 10.
As shown in fig. 2, the drum 30 has a bottomed cylindrical shape with one end open, and stores laundry. The drum 30 is installed in the outer tub 20 so as to open toward the laundry inlet 21 of the outer tub 20. A plurality of fine holes may be formed in the outer circumferential wall and the bottom wall of the drum 30, so that the washing water and the heated air generated from the heat pump device 40 can flow between the outer tub 20 and the drum 30. The drum 30 is driven by a motor, not shown, and is rotatable about a rotation axis X extending in the horizontal direction. The rotation direction of the drum 30 may be clockwise in fig. 2, may be counterclockwise, or may be constantly switched between clockwise and counterclockwise. In addition, the rotation axis X of the drum 30 may be inclined upward toward the laundry inlet 21.
As shown in fig. 1 to 3, a heat pump device 40 of an integrated structure is disposed in an upper space portion 14 located above the outer tub 20 in the casing 10, and the heat pump device 40 dries laundry in the drum 30 with heated air. As shown in fig. 2, upper space 14 is a space sandwiched between the ceiling plate and the upper arc-shaped outer peripheral surface of outer tub 20 in the vertical direction, and includes not only a space above highest portion 20U of outer tub 20 but also spaces on both right and left sides of highest portion 20U and slightly below highest portion 20U (for example, a space in which suspension spring 23 is disposed in fig. 2).
As shown in fig. 4, 5, and 7, the heat pump apparatus 40 includes: an air path housing 50 having an air inlet 55 and an air outlet 56, the air inlet 55 and the air outlet 56 being respectively communicated with the inner cavity of the drum 30; an evaporator 60, which is a microchannel evaporator, disposed in the air path casing 50, for dehumidifying air guided out from the drum 30; a condenser 70, which is a microchannel condenser, disposed on the downstream side in the air flow direction of the evaporator 60 in the air path casing 50, and configured to heat the air passing through the evaporator 60; and a fan 80 disposed upstream of the evaporator 60 in the air path casing 50 in the air flow direction, for causing air to flow, so as to introduce the air in the drum 30 into the air path casing 50 through the air inlet 55, and to introduce the air having passed through the evaporator 60 and the condenser 70 into the drum 30. Further, the heat pump apparatus 40 includes a compressor 90, and the compressor 90 compresses the refrigerant flowing through the evaporator 60 and the condenser 70.
As shown in fig. 5 to 7, the air path case 50 includes: an air inlet 51 extending substantially in the vertical direction and having an air inlet 55 at a lower end thereof, the lower end of the air inlet 51 being connected to the outer tub 20 at a rear end side of the outer circumferential surface of the outer tub 20 and communicating with the inner cavity of the drum 30 via the fine holes of the wall portion of the drum 30, as shown in fig. 13; an air outlet 52 extending substantially in the vertical direction and having an air outlet 56 at a lower end thereof, the lower end of the air outlet 52 being connected to the outer tub 20 at a front end side of the outer circumferential surface of the outer tub 20 (i.e., the laundry inlet 21 side) and communicating with the inner cavity of the drum 30 through an opening of the drum 30 corresponding to the laundry inlet 21, as shown in fig. 13; and a housing body 53 connected between the inlet 51 and the outlet 52. Further, an expandable bellows 54 is interposed between the air inlet 51 and the housing main body 53, thereby preventing vibration of the outer tub 20 from being transmitted to the housing main body 53 via the air inlet 51. Although not shown, for example, an expandable bellows may be interposed between the gas outlet 52 and the case main body 53. In addition, in the present embodiment, by connecting the air outlet 52 to the front end side of the outer circumferential surface of the outer tub 20, the air heated by the heat pump device 40 can be directly supplied into the drum 30, and the air is not dispersed by the fine holes of the drum 30, as compared with the case where the air outlet 52 is connected to the rear end side of the outer circumferential surface of the outer tub 20, and the laundry in the drum 30 can be dried more efficiently.
As shown in fig. 5 to 7, the housing main body 53 has an upper housing 57 and a lower housing 58. The lower case 58 is formed into a substantially cup shape that opens upward, and includes a bottom wall portion 581 and a peripheral wall portion 582. An air inlet 51 is connected to the bottom wall 581 near the rear end thereof via a bellows 54, an air outlet 52 is connected to the front peripheral wall 582, and the air outlet 52 is located substantially directly in front of the air inlet 51. The upper case 57 is substantially plate-shaped and is fixed to the upper end of the peripheral wall 582 of the lower case 58 with screws or the like. In an internal space of the casing main body 53 surrounded by the upper casing 57 and the lower casing 58, an evaporator 60, a condenser 70, and a fan 80 are disposed. The front peripheral wall 582 is continuously provided with a compressor housing 583 forward, and the compressor housing 583 is formed into a substantially bottomed tubular shape that opens upward. The compressor 90 is mounted in the compressor housing 583, and is disposed outside the internal space of the casing main body 53. Thus, the evaporator 60, the condenser 70, the fan 80, and the compressor 90 are disposed in the upper space portion 14 by the casing main body 53 in an integrated structure.
As shown in fig. 7 to 9, the evaporator 60 is a substantially plate-shaped microchannel evaporator, and a pair of plate surfaces facing each other are a windward surface 61 and an air-out surface 62, respectively. The evaporator 60 absorbs heat from the refrigerant flowing inside to cool the high-humidity air flowing outside through the evaporator 60, and the water vapor in the air is condensed on the surface of the evaporator 60 to be precipitated as condensed water, thereby obtaining dry air. As shown in fig. 9, in the upper space portion 14, the evaporator 60 is disposed such that the windward surface 61 is located at the upper side and the air-out surface 62 is located at the lower side, and the windward surface 61 and the air-out surface 62 are inclined with respect to a horizontal line in the left-right direction, and the height of the right end is higher than that of the left end, that is, the right end becomes the upper end 63 and the left end becomes the lower end 64. Further, the evaporator 60 is located directly above the rotation axis X of the drum 30. Here, "the evaporator 60 is located directly above the rotation axis X of the drum 30" means that there is one or more intersection points between the orthographic projection of the evaporator 60 on the horizontal plane and the orthographic projection of the rotation axis X of the drum 30 on the horizontal plane.
As shown in fig. 7 to 9, the condenser 70 is a substantially plate-shaped microchannel condenser, and a pair of plate surfaces facing each other are a windward surface 71 and an air-out surface 72, respectively. The condenser 70 heats dry air flowing through the condenser 70 at the outside by heat release of the refrigerant flowing inside, thereby obtaining high-temperature and dry air. As shown in fig. 9, in the upper space portion 14, the condenser 70 is disposed such that the windward surface 71 is located on the lower side and the air-out surface 72 is located on the upper side, and the windward surface 71 and the air-out surface 72 are inclined with respect to a horizontal line in the left-right direction, and the height of the left end is higher than that of the right end, that is, the left end is an upper end 73 and the right end is a lower end 74.
As shown in fig. 9, in the upper space portion 14, the condenser 70 is located on the right side of the evaporator 60, and the evaporator 60 and the condenser 70 are arranged in the left-right direction, in other words, in the rotational direction of the drum 30 about the rotational axis X. Specifically, the upper end 63 of the evaporator 60 and the upper end 73 of the condenser 70 are close to each other, the lower end 64 of the evaporator 60 extends obliquely downward toward one side (left side) in the rotational direction of the drum 30, the lower end 74 of the condenser 70 extends obliquely downward toward the other side (right side) in the rotational direction of the drum 30, and the evaporator 60 and the condenser 70 are arranged in a substantially inverted V shape as viewed in the direction of the rotational axis X of the drum 30 (front-rear direction). Further, the lower end 64 of the evaporator 60 is at a higher elevation than the lower end 74 of the condenser 70. Further, a substantially V-shaped partition plate 571 is provided on the surface of the upper case 57 so as to be recessed downward, and the partition plate 571 is provided between the evaporator 60 and the condenser 70 and is in contact with the upper end 63 of the evaporator 60 and the upper end 73 of the condenser 70, respectively.
The above-mentioned "evaporator 60 and condenser 70 are arranged along the rotation direction of drum 30" means that the position of evaporator 60 in the rotation direction of drum 30 is different from the position of condenser 70 in the rotation direction of drum 30 as viewed in the direction of rotation axis X of drum 30, and as a typical example, there is no intersection between the orthographic projection of evaporator 60 on the vertical plane orthogonal to the front-rear direction and the orthographic projection of condenser 70 on the vertical plane orthogonal to the front-rear direction, and it is needless to say that the configuration shown in fig. 9 includes a configuration in which evaporator 60 arranged parallel to the horizontal plane and condenser 70 arranged parallel to the horizontal plane are sequentially arranged in the left-right direction.
As shown in fig. 7 and 8, the fan 80 is disposed behind the condenser 70 in the casing main body 53 of the air-path casing 50, and is disposed at a portion of the casing main body 53 connected to the air inlet 51 and the bellows 54. That is, the condenser 70 and the fan 80 are arranged along the direction of the rotation axis X of the drum 30 (i.e., the front-rear direction). Further, the fan 80 is located upstream of the evaporator 60 in the air path housing 50 in the air flow direction.
The fan 80 is disposed such that the rotation axis extends in the vertical direction. By operating the fan, the low-temperature and high-humidity air in the drum 30 is sucked into the casing main body 53 from the rear side of the drum 30 through the air inlet 51 and the bellows 54; the low-temperature and high-humidity air sucked into the casing main body 53 passes through the evaporator 60 from the upper windward surface 61, and water vapor in the air is condensed on the surface of the evaporator 60 by the heat absorption action of the refrigerant in the evaporator 60 to be precipitated as condensed water, thereby obtaining low-temperature dry air; the low-temperature dried air coming out of the air outlet surface 62 of the evaporator 60 passes through the condenser 70 from the lower windward surface 71, and the air is heated by the heat release action of the refrigerant in the condenser 70, thereby obtaining high-temperature dried air; the high-temperature dry air coming out of the air outlet surface 72 of the condenser 70 enters the drum 30 from the front side of the drum 30 through the air outlet member 52; the high temperature dry air contacts with the damp clothes in the drum 30, and the moisture contained in the clothes is evaporated into water vapor to be taken away, so that the air becomes low temperature and high humidity air; the air of low temperature and high humidity is sucked into the casing main body 53 again from the rear side of the drum 30 through the air inlet 51 and the bellows 54.
The air path in the air path casing 50 is divided into: a 1 st air passage region S1 that is a region from the intake port 55 of the air intake member 51 to the windward surface 61 of the evaporator 60 in the housing main body 53 via the bellows 54, in other words, a region located on the upstream side of the evaporator 60 in the air flow direction; a 2 nd air passage region S2 located between the air outlet surface 62 of the evaporator 60 and the windward surface 71 of the condenser 70 in the casing main body 53, in other words, located below the evaporator 60 and the condenser 70; and a 3 rd air passage region S3 extending from the air outlet surface 72 of the condenser 70 to the air outlet 56 of the air outlet 52, in other words, a region located on the downstream side of the condenser 70 in the air flow direction.
As shown in fig. 8, the 1 st air-passage region S1 is formed so that the air blown out from the fan 80 turns and flows toward the windward surface 61 of the evaporator 60 along the direction of the rotation axis X of the drum 30. The 1 st air passage region S1 has a flared shape with a gradually increasing width in plan view, and turns from the air outlet 81 provided on the side of the fan 80 and extends in the direction of the rotation axis X of the drum 30.
As shown in fig. 11, a slope 585 is provided on the bottom wall 581 of the duct case 50 defining the 1 st duct region S1. The slope 585 is inclined upward as going from the rear to the front, in other words, the slope 585 is inclined upward as approaching the evaporator 60. The angle α of the slope 585 to the horizontal is greater than 90 ° and less than 180 °. More preferably, the angle α formed by the slope 585 and the horizontal plane is 120 ° to 150 °. In addition, the dome 585 is formed parallel to the flow of air (including "substantially parallel") through the dome 585.
The ramp 585 has a top end 5851 and a bottom end 5852. The bottom end 5852 is located in the turned portion of the 1 st air-path region S1, and the slope 585 extends in the direction of the rotation axis X of the drum 30 (i.e., the front-rear direction), that is, the slope 585 has no turning portion in a plan view. However, the slope 585 may extend in the direction of the rotation axis X of the drum 30 after turning from the exhaust port 81 provided on the side of the fan 80.
The bottom end 5852 of the slope 585 is curved in an arc shape and connected to another portion of the bottom wall portion 581 of the air-path case 50 (i.e., a portion located on the upstream side of the slope 585).
The slope 585 does not extend to the windward surface 61 of the evaporator 60 in the front-rear direction, and a tip 5851 of the slope 585 is curved in an arc shape and connected to another portion of the bottom wall portion 581 of the air-path case 50 (i.e., a portion located on the downstream side of the slope 585). However, the slope 585 may extend in the front-rear direction to the windward surface 61 of the evaporator 60, and there may be no other portion of the bottom wall portion 581 between the tip 5851 of the slope 585 and the windward surface 61 of the evaporator 60. In addition, both the bottom end 5852 and the top end 5851 of the slope 585 are not necessarily curved in an arc shape, and at least one of the both may be curved in an arc shape and connected to another portion of the bottom wall portion 581 of the air-path case 50.
Further, the tip 5851 of the slope 585 is higher than the windward surface 61 of the evaporator 60, but the present invention is not limited thereto, and the tip 5851 of the slope 585 may be flush with the windward surface 61 of the evaporator 60. That is, the tip 5851 of the slope 585 is not lower than the windward surface 61 of the evaporator 60, so that the air flowing through the air path casing 50 can be reliably guided to the windward surface 61 of the evaporator 60, and the flowing air can be prevented from blowing to the side surface of the evaporator 60.
In addition, as shown in FIG. 12, the slope 585 is inclined in the rotation direction of the drum 30 (i.e., the left-right direction) in addition to the direction of the rotation axis X of the drum 30 (i.e., the front-rear direction). Specifically, the tip 5851 of the slope 585 slopes downward as it goes from the right side to the left side. In other words, the top 5851 of the slope 585 inclines downward as it goes from the upper end 63 to the lower end 64 of the evaporator 60 in the rotational direction of the drum 30. As can be seen from fig. 10 and 12, the slope of the tip 5851 of the ramp 585 in the left-right direction substantially coincides with the slope of the evaporator 60 in the left-right direction. In addition, although not shown, the slope 585 as a whole or at least a portion including the top end 5851 is inclined downward from the right side to the left side in addition to the top end 5851. In addition, although not shown, the other portion of the bottom wall portion 581 of the air path casing 50 located between the tip 5851 of the slope 585 and the windward surface 61 of the evaporator 60 is inclined in the left-right direction at substantially the same inclination as the tip 5851 of the slope 585.
As shown in fig. 10, the bottom wall portion 581 of the air path case 50 defining the 2 nd air path region S2 extends in an arc shape along the outer peripheral surface of the outer tub 20, and the bottom wall portion 581 of the air path case 50 defining the 2 nd air path region S2 is provided with a drain opening 584 at a position below the condenser 70, and the drain opening 584 is connected to a drain pipe for draining the washing water in the outer tub 20 via a hose or the like not shown.
As shown in fig. 7 and 8, the compressor 90 is located in the upper space portion 14, is disposed in the compressor housing portion 583 in front of the condenser 70, and is disposed in the vicinity of the right side of the air outlet 52. In the direction of the rotation axis X of the drum 30, the compressor 90 is disposed on the side (front side) of the laundry inlet 21 with respect to the condenser 70, and the fan 80 is disposed on the opposite side (rear side) of the compressor 90 with respect to the condenser 70. Further, the compressor 90 may be disposed in the upper space portion 14 at the rear of the evaporator 60.
By operating the compressor 90, the low-temperature and low-pressure gaseous refrigerant is compressed to become a high-temperature and high-pressure gaseous refrigerant; then, the refrigerant is sent into the condenser 70, and becomes a low-temperature and high-pressure refrigerant by heat dissipation in the condenser 70; then, the refrigerant passes through the expansion device 91 to become a low-temperature low-pressure gas-liquid two-phase refrigerant; then; the refrigerant enters the evaporator 60, and becomes a low-temperature low-pressure gaseous refrigerant by absorbing heat; thereafter, the refrigerant returns to the compressor 90 and is compressed again.
The drum-type laundry treatment apparatus 1 of the present embodiment operates as follows. Laundry is put into the drum 30 through the laundry inlet 21, and the laundry is washed as in a conventional washing machine. When the washed laundry needs to be dried, the fan 80 and the compressor 90 are operated at the same time, and the evaporator 60 and the condenser 70 generate high-temperature dry air to dry the laundry in the drum 30.
In the above-described embodiment, the configuration in which the fan 80 is disposed behind the condenser 70 as shown in fig. 8 has been described, but the present invention is not limited to this. For example, the fan 80 may be disposed in front of the condenser 70. That is, the condenser 70 and the fan 80 may be arranged along the direction of the rotation axis X of the drum 30 (i.e., the front-rear direction).
The present invention has been described above with reference to the embodiments and modifications thereof. However, the present invention is not limited to the above-described embodiments and modifications thereof. Variations that may be obtained by applying various modifications to the above-described embodiments as would occur to those skilled in the art are also included in the present invention, without departing from the spirit of the utility model and the scope of the meaning expressed by the terms of the claims.
