Abstract
A washing and drying integrated machine (1) with improved maintainability is provided with: an outer cylinder (3); a substantially cylindrical drum (5) rotatably disposed in the outer cylinder (3); and a first exhaust duct (60) which is communicated with the inside of the outer cylinder (3) through an inflow port formed in the upper part Zhou Mianbi of the outer cylinder (3) as an exhaust duct, and the washing and drying all-in-one machine (1) is provided with an exhaust duct washing mode for washing the inside of the first exhaust duct (60) as an operation mode.
Description
The invention relates to a washing and drying integrated machine.
As a conventional washing and drying machine, there is a washing and drying machine (for example, see patent document 1) including: an outer cylinder; a substantially cylindrical drum rotatably disposed in the outer cylinder; an intake duct (not shown) disposed at the upper right portion of the outer cylinder Zhou Mianbi; and a first exhaust duct disposed at the upper left portion of Zhou Mianbi of the outer cylinder. A second exhaust duct communicating with the first exhaust duct is provided above the first exhaust duct, and a fan and a filter are disposed inside the second exhaust duct.
When a drying process is performed in the washing and drying machine, air for drying the laundry is supplied into the tub from the air intake duct by driving the fan, and the air in the tub is discharged from the air discharge duct. Dust and lint (lint, fluff, etc.) contained in the air flowing into the second exhaust duct are captured by the filter.
In the conventional integrated washing and drying machine, the first exhaust duct is formed in a hollow substantially prismatic shape having a front surface, a rear surface, an upper surface, a left side surface, and a lower surface constituted by a circumferential surface wall of the outer tub and extending in the front-rear direction. In the drying process of the washing and drying integrated machine, the air flowing into the first exhaust duct from the inflow port collides against the upper inner circumferential surface of the rear part of the first exhaust duct opposite to the inflow port, the upper inner circumferential surface is formed at the upper corner part where the upper surface and the rear surface are vertically connected, and dust and the like contained in the air are easily accumulated at the upper corner part. Therefore, maintenance is required to remove dust and the like accumulated on the inner circumferential surface of the exhaust pipe by manual work.
In addition, some conventional washing and drying machines have a drum washing mode as an operation mode, and the washing and drying machines can be operated in the drum washing mode before the washing operation, and generally perform washing in the drum by an agitation force of a drum rotation speed (for example, 40 to 45 rpm) at the time of normal washing. Therefore, the water flow during the drum washing does not reach the upper corner of the first exhaust duct, and it is difficult to remove dust and the like accumulated in the upper corner of the first exhaust duct.

Disclosure of Invention
Problems to be solved by the invention
Accordingly, an object of the present invention is to provide a washing and drying machine having an exhaust duct cleaning mode in which dust and the like contained in air flowing from an outer cylinder into an exhaust duct are removed even when the dust and the like are accumulated on an inner peripheral surface of the exhaust duct.
Means for solving the problems
The washing and drying integrated machine of the invention is characterized by comprising: an outer cylinder; a substantially cylindrical drum rotatably disposed in the outer cylinder; and an exhaust duct communicating with the inside of the outer cylinder through an inflow port formed in an upper portion Zhou Mianbi of the outer cylinder, and the operation mode includes an exhaust duct cleaning mode for cleaning the inside of the exhaust duct.
In the integrated washer dryer of the present invention, it is preferable that the inlet port is disposed at a position eccentric to the rotation axis of the drum in either of the left and right directions in a front view, the exhaust duct is a hollow box-shaped member extending from the front side to the back side and having one end side facing the inlet port, and the drum is rotationally driven in a predetermined rotational direction so that the upper end portion of the drum moves from a side where the inlet port is not eccentric to a side where the inlet port is eccentric in the vicinity of the upper portion Zhou Mianbi of the outer cylinder in the exhaust duct washing mode.
Preferably, in the integrated washing and drying machine of the present invention, the operation mode further includes a drum washing mode for washing an inside of the drum, and in the exhaust duct washing mode, the drum is rotationally driven at a rotational speed higher than a rotational speed in the drum washing mode, and an amount of water supplied into the outer tub is larger than an amount of water supplied into the outer tub in the drum washing mode.
Preferably, in the integrated washing and drying machine of the present invention, the exhaust duct cleaning mode includes: a first exhaust duct cleaning mode in which the amount of water supplied into the outer tub is a first amount of water; and a second exhaust duct cleaning mode, which is performed after the first exhaust duct cleaning mode, and in which a second amount of water, which is larger than the first amount of water, is supplied into the outer tub.
Effects of the invention
According to the present invention, even when dust and the like contained in the air flowing into the exhaust duct from the outer cylinder are accumulated on the inner circumferential surface of the exhaust duct, the dust and the like accumulated on the inner circumferential surface of the exhaust duct can be removed by causing water to flow into the exhaust duct from the outer cylinder by operating in the exhaust duct cleaning mode. This improves maintenance performance and reduces the necessity of cleaning the inside of the exhaust pipe by manual work. This can suppress the reduction in drying performance due to the reduction in the amount of exhaust gas caused by the adhesion of dust or the like to the exhaust duct, and the occurrence of a failure due to the reduction in the amount of exhaust gas, and can reduce the number of times the exhaust duct is cleaned manually.
According to the present invention, in the exhaust duct cleaning mode, water in the outer cylinder is likely to be accumulated in the exhaust duct after flowing into the exhaust duct. Therefore, in the exhaust pipe cleaning mode, the water flowing from the outer cylinder into the exhaust pipe can remove dust and the like accumulated in a wide range of the inner peripheral surface of the exhaust pipe.
According to the present invention, in the exhaust duct washing mode, the amount of water contained in the outer tub is larger than that in the drum washing mode, and the rotation speed of the drum is larger than that in the drum washing mode, so that a large amount of water flows from the outer tub into the exhaust duct, and dust and the like accumulated on the inner peripheral surface of the exhaust duct can be effectively removed.
According to the present invention, in the exhaust pipe cleaning mode, first, a strong water flow is generated inside the exhaust pipe in a state where the water level in the exhaust pipe is low to remove dust and the like from the inner circumferential surface of the exhaust pipe, and then a gentle water flow is generated inside the exhaust pipe in a state where the water level in the exhaust pipe is high to wash away the dust and the like removed from the inner circumferential surface of the exhaust pipe.

A water supply port 12 connected to an external water supply facility or the like is provided on the rear surface of the housing 2, and the water supply port 12 and the outer cylinder 3 are connected by a water supply pipe 13. When the water supply valve 15 attached to the middle portion of the water supply pipe 13 is opened, the water supplied from the water supply port 12 through the water supply pipe 13 flows into the outer cylinder 3 and is stored in the outer cylinder 3.
A drain port 16 is formed in the lowermost portion of the outer cylinder 3, and a drain pipe 17 is connected to the drain port 16. When the drain valve 18 attached to the middle of the drain pipe 17 is opened, the water stored in the outer cylinder 3 is discharged to the outside of the machine through the drain pipe 17.
A drum 5 for accommodating laundry is disposed in the outer tub 3. The drum 5 is formed in a cylindrical shape and is provided to be rotatable about a central axis N. The drum 5 has a laundry entrance 20 formed in the center of the front surface thereof for putting in and taking out laundry. A plurality of holes 5a are bored in the circumferential wall of the drum 5 over substantially the entire circumference, and the inside of the drum 5 communicates with the outer cylinder 3 through the holes 5 a. Thus, for example, water accumulated in the outer tub 3 during the washing process may also flow into the drum 5 through the hole 5 a.
The rear wall of the drum 5 is provided with a rotary shaft 30 projecting rearward along the central axis N. The center of the rotating shaft 30 is rotatably held by a bearing 31 of the outer cylinder 3, and a drum pulley 32 is attached to the rear end of the rotating shaft 30.
A motor 33 for rotationally driving the drum 5 is disposed in a lower rear portion of the outer cylinder 3. A drive shaft 34 for transmitting the driving force of the motor 33 is provided to the motor 33 to be freely rotatable. The drive shaft 34 extends forward, and a motor pulley 35 is attached to a distal end portion thereof. A belt 36 is wound around the motor pulley 35 with a predetermined tension between the drum pulley 32 and the motor pulley 35, and when the motor 33 is driven, the driving force is transmitted to the rotary shaft 30 via the motor pulley 35, the belt 36, and the drum pulley 32, and the drum 5 rotates.
The first air intake duct 50 is provided at the upper right portion of Zhou Mianbi of the outer cylinder 3. A substantially rectangular inflow port 51 is formed slightly in front of the center portion of the lower surface of the first intake duct 50 (the outer peripheral surface of Zhou Mianbi of the outer cylinder 3), and the intake duct 50 communicates with the outer cylinder 3 via the inflow port 51. A circular intake duct inflow port 52 is formed in a rear portion of the upper surface of the first intake duct 50.
A second intake duct 53 is provided above the first intake duct 50. The second intake duct 53 is fixed to the casing 2 by a fixing member not shown. An intake duct inlet 54 is formed at a lower end portion of the second intake duct 53 in the front, and communicates with the outside of the machine. A circular intake duct outlet 55 is formed at the lower end of the second intake duct 53 on the side opposite to the side where the intake duct inlet 54 is formed. The intake duct inlet 52 of the first intake duct 50 and the intake duct outlet 55 of the second intake duct 53 are connected by an intake duct connecting pipe 56.
A gas burner (gas burner) 57 is disposed inside the second intake duct 53. The gas burner 57 is a gas burner that burns gas supplied from an external gas supply path (not shown), for example, and heats surrounding air by the combustion heat, and the air in the second intake duct 53 is heated by turning on the gas burner 57. That is, at the time of the drying process, heated air for drying the laundry is generated by heating of the gas burner 57.
The first exhaust duct 60 is provided in the upper left portion of Zhou Mianbi of the outer cylinder 3. The first exhaust duct 60 includes: the front surface, the back surface, the upper surface, the left side surface, and the lower surface formed by the peripheral surface wall of the outer cylinder 3 are hollow box-shaped members extending in the front-rear direction. As described above, the first exhaust duct 60 is a hollow box-shaped member that extends from the front side to the rear side and has the rear side facing the inlet 61.
A substantially rectangular inflow port 61 is formed in a rear portion of a lower surface of the first exhaust duct 60 (an outer peripheral surface of Zhou Mianbi of the outer cylinder 3), and the first exhaust duct 60 communicates with the outer cylinder 3 via the inflow port 61. A circular exhaust duct outlet 62 is formed in the upper surface of the first exhaust duct 60.
A second exhaust duct 63 is provided above the first exhaust duct 60. The second exhaust duct 63 is fixed to the case 2 by a fixing member not shown, and an exhaust duct inflow port 64 is formed at a front lower end portion of the second exhaust duct 63. The exhaust duct outlet 62 of the first exhaust duct 60 and the exhaust duct inlet 64 of the second exhaust duct 63 are connected by an exhaust duct connecting pipe 65.
Further, an exhaust duct outflow port 66 is formed at an upper end portion of the other end of the second exhaust duct 63 on the side opposite to the side where the exhaust duct inflow port 64 is formed. The exhaust duct outflow port 66 protrudes outward from the upper surface of the casing 2, and the outer cylinder 3 and the outside of the machine communicate with each other via the first exhaust duct 60, the exhaust duct connecting pipe 65, and the second exhaust duct 63.
A fan 67 is disposed inside the second exhaust duct 63. The fan 67 is driven, for example, during the drying process, and is used to flow the air in the drum 5 and the tub 3 out of the machine from the exhaust duct outflow port 66.
Further, a filter 68 is provided between the fan 67 and the exhaust duct inflow port 64 inside the second exhaust duct 63. The filter 68 is inclined obliquely upward from the front side toward the rear side to divide the interior of the second exhaust duct 63 into the exhaust duct inflow port 64 side and the fan 67 side, and captures dust and lint (lint, fluff, etc.) contained in the air from the exhaust duct inflow port 64.
An operation opening 8 for communicating the inside of the second exhaust duct 63 forward is formed in the front surface of the second exhaust duct 63, and an operation window 8a is opened in a position facing the operation opening 8 in the front surface wall of the casing 2. The operation opening 8 and the operation window 8a are always closed by the cover 8b, and when the operation opening 8 and the operation window 8a are opened by operating the cover 8b, the inside of the second exhaust duct 63 is exposed to the front, and maintenance of the filter 68 and the like can be performed.
As shown in fig. 5, the washing and drying integrated machine 1 of the present embodiment has the following operation modes: a laundry washing mode for washing the laundry accommodated in the drum 5; a drum washing mode for washing the inside of the drum 5 before the washing operation of the laundry; and an exhaust duct washing mode for washing the inside of the first exhaust duct 60.
(washing mode)
The laundry washing mode is an operation in an operation mode corresponding to an operation of the operation unit 80 provided in the cabinet 2 as shown in fig. 6 (a). In the integrated washing and drying machine 1 of the present embodiment, the drum 5 is rotationally driven at a drum rotation speed of, for example, 40 to 45rpm in the laundry washing mode. The amount of water supplied in the laundry washing mode (the amount of water supplied into outer tub 3) may be set to an amount of water appropriate for the operation of operation unit 80.
(Drum cleaning mode)
When the drum washing button 81 provided in the cabinet 2 is pressed with the door 11 closed, the drum washing mode is started. If the drum washing button 81 provided in the casing 2 is pressed in a state where the door 11 is opened, a sound "please press the door after closing" is played.
In the drum washing mode, a low amount of water (water level 3 degrees in the standard setting, but may be set to water level 2 to 5 degrees) is supplied into the outer tub 3, and the drum 5 is rotated for 2 minutes (may be set to 1 to 5 minutes) in the standard setting so as to alternately repeat left rotation and right rotation. In the drum washing mode, the drum 5 is rotated at a drum rotation speed of, for example, 40 to 45 rpm. As described above, in the integrated washer dryer 1 of the present embodiment, the drum 5 is rotationally driven at substantially the same rotational speed as that in the laundry washing mode in the drum washing mode.
Here, the amount of water supplied into the outer cylinder 3 will be described. As shown in fig. 7, in a state where drum 5 is stopped, the horizontal height at which the lower end of drum 5 is disposed is set to 0 degree, the horizontal height at which the center of drum 5 is disposed is set to 10 degrees, and these horizontal heights are divided into ten equal parts and set to 1 degree to 9 degrees, respectively. Therefore, for example, in the drum washing mode, when water of a level of 3 degrees is supplied, water is present only below the level of 1/4 in the height direction of the drum 5.
(exhaust pipe cleaning mode)
After the drum washing button 81 provided in the casing 2 is pressed for 10 seconds with the door 11 opened, the exhaust duct washing mode is started with the door 11 closed. In the integrated washing and drying machine 1 of the present embodiment, the exhaust duct washing mode is started only by the above-described operation in a state where the number of maintenance washing operations stored in the integrated washing and drying machine is reset.
As shown in fig. 6 (a), a front panel 82 is provided on the upper front portion of the case 2. The front plate 82 can be unlocked by inserting a dedicated key into a lock hole 83 formed in a lower end portion of the front plate 82, and can be opened by rotating upward with an upper end of the front plate 82 as a fulcrum. As shown in fig. 6 (b), when the front panel 82 is opened, the reset button 84 is operable, and when the reset button 84 is operated, the number of maintenance washing operations is reset.
As described above, the maintenance and cleaning operation count cannot be reset unless the owner of the integrated washer dryer 1 opens the front panel 82 with a dedicated key. Therefore, the person other than the owner of the integrated washing and drying machine 1 cannot perform the operation in the exhaust duct cleaning mode in succession to the operation in the exhaust duct cleaning mode in a state where the operation in the exhaust duct cleaning mode has been completed.
In the integrated washing and drying machine 1 of the present embodiment, the exhaust duct washing mode is performed by two operations, i.e., the first exhaust duct washing mode and the second exhaust duct washing mode performed after the first exhaust duct washing mode.
In the first exhaust pipe washing mode, a medium amount of water (water level 6 °) is supplied into the outer tub 3, and the drum 5 is rotated in the left rotation direction at the pipe washing rotation speed for 2 minutes. The water supply amount in the first exhaust duct cleaning mode is not limited to 6 degrees, but a water flow is likely to occur in the first exhaust duct 60 as long as the water level is, for example, 5 to 7 degrees.
The line washing rotation speed in the exhaust line washing mode is set according to the diameter of the drum 5. For example, when the diameter of the drum 5 of the integrated washer dryer 1 is 600mm, the pipe cleaning rotation speed is set to 90 to 130rpm, preferably about 120 rpm. When the diameter of the drum 5 of the integrated washing and drying machine 1 is 800mm, the pipe washing rotation speed is set to 60 to 100rpm, preferably about 80 rpm. As described above, the rotation speed of the drum 5 in the first exhaust duct washing mode is greater than the rotation speed of the drum 5 in the drum washing mode.
In the integrated washing and drying machine 1 of the present embodiment, the inlet 61 is disposed at a position eccentric to the rotation axis of the drum 5 in the left direction in the front view, and in the exhaust duct cleaning mode, the drum 5 is rotationally driven in the left rotation direction so that the upper end portion of the drum moves from the right side (the side where the inlet 61 is not eccentric) to the left side (the side where the inlet 61 is eccentric) in the vicinity of the upper portion Zhou Mianbi of the outer cylinder 3.
Since the water supply amount in the first exhaust duct cleaning mode is the medium water amount (water level 6 degrees), water is supplied into the outer tub 3 to a level slightly above the level 1/4 of the drum 5 in the height direction. In this way, the water supply amount in the first exhaust duct washing mode is larger than that in the drum washing mode.
In the second exhaust duct cleaning mode, a high water amount (water level 9 °) is supplied into the outer cylinder 3, and the drum 5 is rotated at the duct cleaning rotation speed for 1 minute. The water supply amount in the second exhaust duct cleaning mode is not limited to the water level of 9 degrees, but the water level in the first exhaust duct 60 rises to such an extent that the water level in the first exhaust duct 60 can be rinsed as long as the water level is, for example, 8 to 10 degrees. The line washing rotation speed is the same as the rotation speed in the first exhaust line washing mode. As described above, the rotation speed of the drum 5 in the second exhaust duct washing mode is greater than the rotation speed of the drum 5 in the drum washing mode. Further, the rotation direction of the drum 5 is the same as that of the first exhaust duct washing mode.
The water supply amount in the second exhaust duct washing mode is higher than the water supply amount in the first exhaust duct washing mode (water level 9 degrees) because of the high water supply amount, and the water is supplied into the outer tub 3 to a level slightly lower than the level 1/2 of the drum 5 in the height direction. As described above, the water supply amount in the second exhaust duct washing mode is greater than the water supply amount in the drum washing mode and greater than the water supply amount in the first exhaust duct washing mode.
As shown in fig. 8, the washing and drying machine 1 of the present embodiment includes a control unit 100 including a microcomputer, and the operation of the washing and drying machine 1 is controlled by the control unit 100. The control unit 100 includes a central control unit (CPU) 101 that controls the entire system, and a memory 102 is connected to the central control unit 101. The control unit 100 causes the microcomputer to execute a program stored in the memory 102, thereby performing a predetermined operation, and the memory 102 temporarily stores data used when the program is executed. The control unit 100 is connected with the operation portion 80, the drum washing button 81, the reset button 84, the water supply valve 15, the motor 33, and the drain valve 18.
The operation flow in the exhaust pipe cleaning mode will be described with reference to fig. 9. Fig. 9 is a flowchart showing an operation flow in the exhaust duct cleaning mode.
< step S1>
In step S1, the central control unit 101 repeatedly determines whether or not the drum washing button 81 is pressed for 10 seconds with the door 11 open. When the central control unit 101 determines that the drum washing button 81 has been pressed for 10 seconds with the door 11 open, the process proceeds to step S2.
< step S2>
In step S2, the central control unit 101 repeatedly determines whether or not the door 11 is closed. When the central control unit 101 determines that the door 11 is closed, the process proceeds to step S3.
< step S3>
In step S3, the central control unit 101 performs an operation in the first exhaust pipe cleaning mode, which is the exhaust pipe cleaning mode. Therefore, in step S3, central control unit 101 controls water supply valve 15 to supply a medium water amount (water level 6 degrees) of water into outer tub 3, and controls motor 33 to rotate drum 5 at the exhaust duct washing rotation speed after the water supply is completed. When the operation in the first exhaust pipe cleaning mode is finished, the process proceeds to step S4.
< step S4>
In step S4, the central control unit 101 performs an operation in the second exhaust pipe cleaning mode, which is the exhaust pipe cleaning mode. Therefore, in step S4, central control unit 101 controls water supply valve 15 to supply a high water amount (water level 9 °) of water into outer tub 3, and controls motor 33 to rotate drum 5 at the exhaust duct washing rotation speed after the water supply is completed. When the operation in the second exhaust pipe cleaning mode is finished, the process proceeds to step S5.
< step S5>
In step S5, the central control portion 101 controls the motor 33 to stop the drum 5 and controls the drain valve 18 to drain the water in the outer tub 3.
The operation in the first exhaust duct 60 when the operation in the exhaust duct cleaning mode is performed will be described with reference to fig. 10 and 11. Fig. 10 and 11 are diagrams illustrating an operation in the first exhaust duct 60 in the exhaust duct cleaning mode.
As shown in (a) of fig. 10, in general, when maintenance in the exhaust pipe cleaning mode is required, dust is deposited on the inner circumferential surface of the first exhaust pipe 60.
In this state, when the first exhaust duct washing mode of the exhaust duct washing mode is started, as shown in fig. 10 (b), water is ejected from the drum 5, and the water flows from the outer tub 3 into the first exhaust duct 60 through the inlet 61. The water flowing from the inlet 61 provided on the rear surface side of the drum 5 also flows to the front surface side. Here, the water flows into the first exhaust duct 60 toward the closed lower end portion on the front surface side of the first exhaust duct 60, and therefore the inflowing water is easily accumulated in the first exhaust duct 60.
In this manner, in the first exhaust duct cleaning mode, since the amount of water supplied into the outer tube 3 is small, the water level in the first exhaust duct 60 is not high as shown in fig. 10 (c). In this state, when the drum 5 rotates, a violent water flow is formed in the first exhaust duct 60. The intense water flow removes dust deposited on the inner circumferential surface of the first exhaust duct 60 from the inner circumferential surface of the first exhaust duct 60.
The second exhaust duct cleaning mode, which is the exhaust duct cleaning mode, is started in a state where dust is removed from the inner peripheral surface of the first exhaust duct 60. In the second exhaust duct cleaning mode, since the amount of water supplied into the outer cylinder 3 is large, the water level in the first exhaust duct 60 becomes high as shown in fig. 11 (a). In this state, the drum 5 rotates to wash the inner circumferential surface of the first exhaust duct 60 so as not to form a strong water flow in the first exhaust duct 60, thereby collecting dust removed from the inner circumferential surface of the first exhaust duct 60.
When the second exhaust duct cleaning mode of the exhaust duct cleaning modes is completed and the drum 5 is stopped and the water in the drum 5 is discharged, as shown in fig. 11 (b), the dust removed from the inner peripheral surface of the first exhaust duct 60 moves from the inlet 61 into the outer tube 3 or the drum 5 and is discharged from the drain port 16 together with the water.
The washing and drying integrated machine 1 of the present embodiment includes: an outer cylinder 3; a substantially cylindrical drum 5 rotatably disposed in the outer cylinder 3; and a first exhaust duct 60 as an exhaust duct communicating with the inside of the outer cylinder 3 through an inflow port 61 formed in an upper portion Zhou Mianbi of the outer cylinder 3, and the operation mode includes an exhaust duct cleaning mode for cleaning the inside of the first exhaust duct 60.
With this configuration, even when dust and the like contained in the air flowing from the outer cylinder 3 into the first exhaust duct 60 are accumulated on the inner peripheral surface of the first exhaust duct 60, the dust and the like accumulated on the inner peripheral surface of the first exhaust duct 60 can be removed by causing water to flow from the outer cylinder 3 into the first exhaust duct 60 by operating in the exhaust duct cleaning mode. Therefore, the maintenance performance is improved, and the necessity of cleaning the inside of the first exhaust duct 60 by manual work is reduced. This can suppress the occurrence of a decrease in drying performance due to a decrease in the amount of exhaust gas caused by dust or the like adhering to the first exhaust duct 60, a malfunction due to a decrease in the amount of exhaust gas, and the like, and can reduce the number of times the interior of the first exhaust duct 60 is cleaned by manual work.
In the integrated washing and drying machine 1 of the present embodiment, the inlet 61 is disposed at a position eccentric to the left direction with respect to the rotation axis of the drum 5 in the front view, the first exhaust duct 60 as an exhaust duct is a hollow box-shaped member disposed to extend from the front side to the back side and having one end side facing the inlet 61, and the drum 5 is rotationally driven in the exhaust duct cleaning mode so that the upper end portion of the drum 5 moves from the side where the inlet 61 is not eccentric to the side where the inlet 61 is eccentric near the upper portion Zhou Mianbi of the outer cylinder 3.
With such a configuration, the water in the outer tub 3 is easily accumulated in the first exhaust duct 60 after flowing into the first exhaust duct 60. Therefore, in the exhaust duct cleaning mode, the water flowing from the outer cylinder 3 into the first exhaust duct 60 can remove dust and the like accumulated in a wide area on the inner peripheral surface of the first exhaust duct 60.
In the integrated washing and drying machine 1 of the present embodiment, the operation mode further includes a drum washing mode for washing the inside of the drum 5, and in the exhaust duct washing mode, the drum 5 is rotationally driven at a rotation speed higher than the rotation speed in the drum washing mode, and the amount of water supplied into the outer tub 3 is larger than the amount of water supplied into the outer tub 3 in the drum washing mode.
With such a configuration, in the exhaust duct washing mode, the amount of water supplied into the outer tub 3 is larger than that in the drum washing mode, and the rotation speed of the drum 5 is larger than that in the drum washing mode, so that a large amount of water flows into the first exhaust duct 60 from the outer tub 3, and dust and the like accumulated on the inner peripheral surface of the first exhaust duct 60 can be effectively removed.
In the integrated washing and drying machine 1 of the present embodiment, the exhaust duct cleaning mode includes: a first exhaust pipe cleaning mode in which the amount of water supplied into the outer cylinder 3 is a first amount (water level 6 degrees); and a second exhaust duct cleaning mode, which is performed after the first exhaust duct cleaning mode, and in which the amount of water supplied into the outer cylinder 3 is a second amount (water level 9 degrees) that is larger than the first amount.
In the exhaust duct cleaning mode, first, in a state where the water level in the first exhaust duct 60 is low, a strong water flow is generated in the first exhaust duct 60 to remove dust and the like accumulated on the inner peripheral surface of the first exhaust duct 60, and then, in a state where the water level in the first exhaust duct 60 is high, a gentle water flow is generated in the first exhaust duct 60 to wash away the dust and the like removed from the inner peripheral surface of the first exhaust duct 60.
While the embodiments of the present invention have been described above, the structure of the embodiments is not limited to the above-described structure, and various modifications are possible.
For example, in the above-described embodiment, the case where the inlet 61 is disposed at a position eccentric to the rotation axis of the drum 5 in the left direction in the front view in the integrated washing and drying machine 1 has been described, but the present invention is not limited thereto. In the integrated washing and drying machine 1, the inlet 61 may be disposed at a position eccentric to the right direction with respect to the rotation axis of the drum 5 in the front view.
In the above embodiment, the case where the first exhaust duct 60 is disposed as a hollow box-shaped member extending from the front side to the rear side and having the rear side facing the inlet 61 in the integrated washing and drying machine 1 has been described, but the present invention is not limited thereto. In the integrated washing and drying machine 1, the first exhaust duct 60 may be a hollow box-shaped member that extends from the front side to the back side and whose front side faces the inlet 61. The structure of the exhaust duct of the present invention is arbitrary.
In the above embodiment, the case where the drum 5 is rotationally driven in the left rotational direction in the exhaust duct cleaning mode has been described, but the present invention is not limited thereto. In the exhaust duct cleaning mode, the drum 5 may be rotationally driven in the right rotational direction. In the exhaust duct cleaning mode, the drum 5 may be rotationally driven so as to alternately repeat the left rotation direction and the right rotation direction.
Although in the above-described embodiment, the exhaust pipe washing mode is implemented by two operations of the first exhaust pipe washing mode and the second exhaust pipe washing mode that is implemented after the first exhaust pipe washing mode, the present invention is not limited thereto. The exhaust pipe cleaning mode may be performed by one operation, or may be performed by three or more operations. Further, although an example of the operation times related to the first exhaust pipe washing mode and the second exhaust pipe washing mode of the exhaust pipe washing mode is shown, these operation times are arbitrary.
Although the above embodiment has been described in the case where the drum washing button 81 is pressed for a long time of 10 seconds with the door 11 open, and the exhaust duct washing mode is started with the door 11 closed, the present invention is not limited thereto. The operation for starting the exhaust pipe cleaning mode, and the like are arbitrary.
In the above embodiment, the operation mode has the drum washing mode, but the present invention may be applied to a washing and drying machine having no drum washing mode in the operation mode.
Other configurations may be variously modified within a range not departing from the gist of the present invention.
