Description
Technical Field
The invention relates to a washing and drying integrated machine.
Background
As a conventional washing and drying integrated machine, there is a washing and drying integrated machine (for example, refer to patent document 1) including: an outer cylinder; a substantially cylindrical drum rotatably disposed in the outer tube; an intake duct (not shown) disposed at the upper right part of the peripheral wall of the outer tube; and a first exhaust duct disposed at the upper left part of the peripheral wall of the outer tube. 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 the drying process is performed in the washing and drying integrated machine, air for drying the laundry is supplied from the suction duct into the outer tub by driving the fan, and the air in the outer tub is discharged from the exhaust 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 washing and drying integrated 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 peripheral surface wall of the outer cylinder and extending in the front-rear direction. During the drying process of the washing and drying integrated machine, air flowing into the first exhaust duct from the inflow port collides with the upper inner peripheral surface of the rear part of the first exhaust duct opposite to the inflow port, and the upper inner peripheral surface is formed at an upper corner 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. Therefore, maintenance is required to remove dust and the like accumulated on the inner peripheral surface of the exhaust duct by manual work.
In addition, there is a conventional washing and drying machine in which the operation mode includes a drum washing mode, and the operation in the drum washing mode can be performed before the washing operation, and the washing and drying machine generally performs washing in the drum by stirring force of the 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 integrated machine having an operation mode in which dust and the like contained in air flowing from an outer tube into an exhaust duct are removed even when the dust and the like are accumulated on an inner peripheral surface of the exhaust duct.
Solution for solving the problem
The washing and drying integrated machine of the invention is characterized in that the washing and drying integrated machine comprises: an outer cylinder; a substantially cylindrical drum rotatably disposed in the outer tube; and an exhaust duct communicating with the inside of the outer tube through an inflow port formed in an upper peripheral wall of the outer tube, wherein the operation mode includes an exhaust duct cleaning mode for cleaning the inside of the exhaust duct.
In the washing and drying integrated machine according to the present invention, preferably, the inlet is disposed at a position eccentric in any one of the right and left directions with respect to the rotation axis of the drum in a front view, the exhaust duct is a hollow box-shaped member disposed so as to extend from the front side toward the rear side and one end side thereof faces the inlet, and in the exhaust duct washing mode, the drum is rotationally driven around a predetermined rotation direction so that the upper end portion of the drum moves from the side not eccentric to the eccentric side of the inlet toward the eccentric side of the inlet in the vicinity of the upper peripheral surface wall of the outer drum.
In the washing and drying integrated machine according to the present invention, preferably, the operation mode further includes a drum washing mode for washing the inside of the drum, and the drum is rotationally driven at a rotational speed higher than that in the drum washing mode in the exhaust duct washing mode, and the amount of water supplied into the outer tub is larger than the amount of water supplied into the outer tub in the drum washing mode.
Preferably, in the washing and drying integrated machine of the present invention, the exhaust duct washing mode includes: a first exhaust duct cleaning mode in which the amount of water supplied into the outer tube is a first amount of water; and a second exhaust duct cleaning mode, which is performed after the first exhaust duct cleaning mode, and which is a mode in which the amount of water supplied into the outer cylinder is a second amount of water that is larger than the first amount of water.
Effects of the invention
According to the present invention, even when dust and the like contained in the air flowing from the outer tube into the exhaust duct are accumulated on the inner peripheral surface of the exhaust duct, the dust and the like accumulated on the inner peripheral surface of the exhaust duct can be removed by flowing water from the outer tube into the exhaust duct by operating in the exhaust duct cleaning mode. This improves maintainability, and reduces the necessity of cleaning the inside of the exhaust duct by manual work. This can suppress occurrence of a decrease in drying performance due to a decrease in exhaust gas amount caused by adhesion of dust or the like to the exhaust duct, a failure due to a decrease in exhaust gas air volume, or the like, and can reduce the number of times of cleaning the exhaust duct by manual work.
According to the present invention, in the exhaust duct cleaning mode, the water in the outer tube flows into the exhaust duct and then is easily stored in the exhaust duct. Therefore, in the exhaust duct cleaning mode, dust and the like accumulated in a wide area on the inner peripheral surface of the exhaust duct can be removed by the water flowing from the outer tube into the exhaust duct.
According to the present invention, in the exhaust duct cleaning mode, the amount of water contained in the interior of the outer tub is larger than the amount of water in the drum cleaning mode, and the rotational speed of the drum is larger than the rotational speed in the drum cleaning 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 duct cleaning mode, first, a strong water flow is generated in the exhaust duct in a state where the water level in the exhaust duct is low to remove dust and the like from the inner peripheral surface of the exhaust duct, and then, a gentle water flow is generated in the exhaust duct in a state where the water level in the exhaust duct is high to flush out dust and the like removed from the inner peripheral surface of the exhaust duct.

As shown in fig. 1, the washing and drying integrated machine 1 of the present embodiment is a commercial washing and drying integrated machine used in a slot machine shop or the like, and has a housing formed of a box 2 which is slightly vertically long.
An outer tube 3 is provided in a substantially central portion of the case 2. The outer tube 3 is formed in a cylindrical shape extending in a substantially horizontal direction by accumulating water supplied from an external water supply device or the like. The central portion of the outer tub 3 is opened in a circular shape, and an opening portion thereof is formed as an outer tub inlet/outlet 6 for inputting and outputting laundry.
An opening 10, which is slightly larger than the outer tube inlet and outlet 6 and is concentric with the outer tube inlet and outlet 6, is formed in a substantially central portion of the front surface of the case 2 in correspondence with the outer tube inlet and outlet 6. A door 11 as an opening/closing door that is opened when a user inputs and takes out laundry is attached to the opening 10 so as to be openable and closable. The door 11 also serves as a door for a laundry inlet/outlet 22 of the drum 5, which will be described later.
The rear surface of the case 2 is provided with a water supply port 12 connected to an external water supply device or the like, and the water supply port 12 is connected to the outer tube 3 via a water supply pipe 13. By setting the water supply valve 15 attached to the middle portion of the water supply pipe 13 to "on", water supplied from the water supply port 12 via the water supply pipe 13 flows into the outer tube 3 and is stored in the outer tube 3.
A drain port 16 is formed at the lowermost portion of the outer tube 3, and a drain pipe 17 is connected to the drain port 16. By setting the drain valve 18 attached to the middle portion of the drain pipe 17 to "open", the water stored in the outer tube 3 is discharged to the outside 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 rotatably provided around a central axis N. The drum 5 has a laundry inlet/outlet 20 formed in a central portion of a front surface thereof for inputting and outputting laundry. A plurality of holes 5a are bored in the peripheral surface wall of the drum 5 almost entirely, and the inside of the drum 5 communicates with the outer cylinder 3 via the holes 5 a. Thus, for example, water stored in the outer tub 3 during the washing process flows into the drum 5 through the holes 5 a.
The rear surface wall of the drum 5 is provided with a rotation shaft 30 protruding rearward along the central axis N. The center portion of the rotary shaft 30 is rotatably held by a bearing 31 of the outer tube 3, and a drum pulley 32 is attached to the rear end portion of the rotary shaft 30.
A motor 33 for rotationally driving the drum 5 is disposed at a position below the rear of the outer tube 3. A drive shaft 34 for transmitting the driving force of the motor 33 is rotatably provided to the motor 33. The drive shaft 34 extends forward, and a motor pulley 35 is attached to a distal end portion thereof. When the motor 33 is driven, the driving force of the belt 36 is transmitted to the rotary shaft 30 via the motor pulley 35, the belt 36, and the drum pulley 32, and the drum 5 is rotated.
A first air intake duct 50 is provided in the upper right portion of the peripheral wall of the outer tube 3. A substantially rectangular inflow port 51 is formed slightly forward of the central portion of the lower surface (outer peripheral surface of the peripheral wall of the outer tube 3) of the first air intake duct 50, and the air intake duct 50 communicates with the outer tube 3 via the inflow port 51. A circular suction duct inflow port 52 is formed at the rear of the upper surface of the first suction duct 50.
A second suction duct 53 is provided above the first suction duct 50. The second suction duct 53 is fixed to the casing 2 by a fixing member not shown. An intake duct inflow port 54 is formed at a front lower end portion of the second intake duct 53, and communicates with the outside. A circular intake duct outlet 55 is formed in a lower end portion of the other end of the second intake duct 53 opposite to the side where the intake duct inlet 54 is formed. The intake duct inflow port 52 of the first intake duct 50 and the intake duct outflow port 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 suction duct 53. The gas burner 57 is, for example, a gas burner that burns a gas supplied from an external gas supply path (not shown) and heats ambient air by the combustion heat thereof, and the gas burner 57 is turned on to heat the air in the second intake duct 53. That is, during the drying process, heated air for drying the laundry is generated by heating of the gas burner 57.
A first exhaust duct 60 is provided at the upper left part of the peripheral wall of the outer tube 3. The first exhaust duct 60 includes: the front surface, the back surface, the upper surface, the left side surface, and the lower surface constituted by the peripheral surface wall of the outer tube 3 are hollow box-like members extending in the front-rear direction. As described above, the first exhaust duct 60 is a hollow box-like member disposed so as to extend from the front surface side toward the rear surface side, and the rear surface side thereof faces the inflow port 61.
A substantially rectangular inflow port 61 is formed in the rear portion of the lower surface (outer peripheral surface of the peripheral wall of the outer tube 3) of the first exhaust duct 60, and the first exhaust duct 60 communicates with the outer tube 3 via the inflow port 61. Further, a circular exhaust duct outlet 62 is formed in an 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 outlet 66 is formed at an upper end portion of the other end of the second exhaust duct 63 opposite to the side where the exhaust duct inlet 64 is formed. The exhaust duct outlet 66 protrudes from the upper surface of the case 2, and the outer tube 3 communicates with the outside through the first exhaust duct 60, the exhaust duct connecting pipe 65, and the second exhaust duct 63.
A fan 67 is disposed in the second exhaust duct 63. The fan 67 is driven, for example, during the drying process, to cause the air in the drum 5 and the outer tub 3 to flow out of the machine from the exhaust duct outflow port 66.
A filter 68 is provided between the fan 67 and the exhaust duct inflow port 64 in 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 inlet 64 side and the fan 67 side, and captures dust and lint (lint, fluff, etc.) contained in the air from the exhaust duct inlet 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 on 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 operation mode of the washing and drying integrated machine 1 of the present embodiment includes: a laundry washing mode for washing laundry accommodated in the drum 5; a drum washing mode for washing the inside of the drum 5 before washing the laundry; and an exhaust duct cleaning mode for cleaning the inside of the first exhaust duct 60.
(washing mode)
The laundry washing mode is operated in an operation mode corresponding to the operation of the operation unit 80 provided in the casing 2 as shown in fig. 6 (a). In the washing and drying integrated machine 1 of the present embodiment, the drum 5 is driven to rotate at a drum rotation speed of 40 to 45rpm, for example, in the washing and cleaning mode. The water supply amount (water supply amount into the outer tub 3) in the laundry washing mode can be appropriately set to an amount corresponding to the operation of the operation unit 80.
(Drum washing mode)
In the case where the drum washing button 81 provided in the casing 2 is pressed with the door 11 closed, the drum washing mode is started. If the drum washing button 81 provided in the cabinet 2 is pressed with the door 11 opened, a sound "please press after closing the door" is played.
In the drum washing mode, water of a low water amount (water level 3 degrees at standard setting but water level 2 to 5 degrees) is supplied into the outer tub 3, and the drum 5 is rotated for 2 minutes (1 to 5 minutes) at standard setting so as to alternately repeat left rotation and right rotation. In the drum washing mode, the drum 5 is rotationally driven at a drum rotation speed of 40 to 45rpm, for example. As described above, in the washing and drying integrated machine 1 of the present embodiment, the drum 5 is rotationally driven at the same rotational speed as the rotational speed in the laundry washing mode in the drum washing mode.
Here, the amount of water supplied into the outer tube 3 will be described. As shown in fig. 7, in a state where the drum 5 is stopped, the horizontal height at which the lower end of the drum 5 is disposed is set to 0 degrees, the horizontal height at which the center of the drum 5 is disposed is set to 10 degrees, and the horizontal heights are set to 1 to 9 degrees by dividing the horizontal height into ten parts. Therefore, for example, in the drum washing mode, when water of 3 degrees is supplied, water is present only below the horizontal height of 1/4 of the height direction of the drum 5.
(exhaust duct cleaning mode)
After the drum washing button 81 provided to the cabinet 2 is operated for 10 seconds in a long time with the door 11 opened, the exhaust duct washing mode is started with the door 11 closed. In the washing and drying integrated machine 1 of the present embodiment, the exhaust duct washing mode is started by the above-described operation only in a state in which the number of maintenance washing operations stored therein has been reset.
As shown in fig. 6 (a), a front panel 82 is provided on the front upper portion of the case 2. The front plate 82 can be unlocked by inserting a dedicated key into a lock hole 83 formed in the lower end portion of the front plate 82, and can be opened by rotating upward about the 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 in an operable state, and when the reset button 84 is operated, the maintenance washing operation count is reset.
As described above, the maintenance washing operation number cannot be reset unless the owner of the washing and drying integrated machine 1 opens the front panel 82 by using a dedicated key. Therefore, it is not possible for a person other than the owner of the washing and drying integrated machine 1 to perform the operation in the exhaust duct washing mode next in a state where the operation in the exhaust duct washing mode has been completed.
In the washing and drying integrated machine 1 of the present embodiment, the exhaust duct washing mode is implemented by two operations, i.e., the first exhaust duct washing mode and the second exhaust duct washing mode that is implemented after the first exhaust duct washing mode.
In the first exhaust duct washing mode, water of a medium water amount (water level 6 degrees) is supplied into the outer tub 3, and the drum 5 is rotated in the left rotation direction for 2 minutes at the duct washing rotational speed. The water supply amount in the first exhaust pipe cleaning mode is not limited to 6 degrees, and water flow is easily generated in the first exhaust pipe 60 as long as the water level is, for example, 5 to 7 degrees.
The pipe cleaning rotational speed in the exhaust pipe cleaning mode is set according to the diameter of the drum 5. For example, when the diameter of the drum 5 of the washing and drying integrated machine 1 is 600mm, the pipe washing rotational speed is set to 90 to 130rpm, preferably about 120 rpm. When the diameter of the drum 5 of the washing and drying integrated machine 1 is 800mm, the pipe washing rotational speed is set to 60 to 100rpm, preferably about 80 rpm. As such, the rotational speed of the drum 5 in the first exhaust duct washing mode is greater than the rotational speed of the drum 5 in the drum washing mode.
In the washing and drying integrated machine 1 of the present embodiment, the inlet 61 is disposed at a position eccentric to the rotation axis of the drum 5 in a left direction in a front view, and in the exhaust duct washing mode, the drum 5 is driven to rotate 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 peripheral surface wall of the outer tube 3.
Since the water supply amount in the first exhaust duct cleaning mode is the water amount (water level 6 degrees), water is supplied into the outer tub 3 to a level slightly above 1/4 of the height of the drum 5. As such, the water supply amount in the first exhaust duct washing mode is greater than that in the drum washing mode.
In the second exhaust duct washing mode, a high water amount (9 degrees in water level) of water is supplied into the outer tub 3, and the drum 5 is rotated at the duct washing rotational speed for 1 minute. The water supply amount in the second exhaust duct cleaning mode is not limited to 9 degrees, and the water level in the first exhaust duct 60 is raised to a level that enables rinsing in the first exhaust duct 60, as long as the water level is, for example, 8 to 10 degrees. Further, the pipe cleaning rotational speed is the same as that of the first exhaust pipe cleaning mode. As such, the rotational speed of the drum 5 in the second exhaust duct washing mode is greater than the rotational 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 a high water amount (water level 9 degrees) and thus is greater than that in the first exhaust duct washing mode, and water is supplied into the outer tub 3 to a level slightly below 1/2 of the height of the drum 5. Thus, the second exhaust duct washing mode supplies more water than the drum washing mode, and more water than the first exhaust duct washing mode.
As shown in fig. 8, the washing and drying integrated machine 1 of the present embodiment includes a control unit 100 including a microcomputer, and the operation of the washing and drying integrated 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 microcomputer executes a program stored in the memory 102 by the control unit 100, thereby performing a predetermined operation, and data and the like used when executing the program are temporarily stored in the memory 102. The control unit 100 is connected to the operation unit 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 pipe cleaning mode.
< step S1 >
In step S1, the central control unit 101 repeatedly determines whether or not the drum washing button 81 is operated for 10 seconds in a long time with the door 11 opened. When the central control unit 101 determines that the drum washing button 81 is pressed for 10 seconds in a state where the door 11 is opened, the process proceeds to step S2.
< step S2 >
In step S2, the central control unit 101 repeatedly determines whether or not the door 11 has been closed. If 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 of the exhaust pipe cleaning mode. Therefore, in step S3, the central control unit 101 controls the water supply valve 15 to supply water of a medium water amount (water level 6 degrees) into the outer tube 3, and controls the motor 33 to rotate the drum 5 at the exhaust pipe washing rotational speed after the water supply is completed. When the operation in the first exhaust pipe cleaning mode is ended, the flow proceeds to step S4.
< step S4 >
In step S4, the central control unit 101 performs an operation in the second exhaust pipe cleaning mode of the exhaust pipe cleaning mode. Therefore, in step S4, the central control unit 101 controls the water supply valve 15 to supply a high water amount (9 degrees water level) of water into the outer tube 3, and controls the motor 33 to rotate the drum 5 at the exhaust pipe washing rotational speed after the water supply is completed. When the operation in the second exhaust pipe cleaning mode is ended, the flow proceeds to step S5.
< step S5 >
In step S5, the central control unit 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 showing the 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 duct cleaning mode is required, dust is deposited on the inner peripheral surface of the first exhaust duct 60.
In this state, when the first exhaust duct cleaning mode of the exhaust duct cleaning mode is started, as shown in fig. 10 (b), water is ejected from the drum 5, and water flows from the outer tub 3 into the first exhaust duct 60 through the inflow port 61. The water flowing in through the inlet 61 provided on the rear surface side of the drum 5 also flows toward the front surface side. Here, the water flows into the first exhaust duct 60 toward the blocked lower end portion on the front side of the first exhaust duct 60, and thus the inflow water is easily accumulated in the first exhaust duct 60.
As described above, in the first exhaust duct cleaning mode, the water amount supplied to the inside of the outer tube 3 is small, and therefore, as shown in fig. 10 (c), the water level in the first exhaust duct 60 is not high. In this state, when the drum 5 rotates, a strong water flow is formed in the first exhaust duct 60. The intense water flow removes dust deposited on the inner peripheral surface of the first exhaust duct 60 from the inner peripheral surface of the first exhaust duct 60.
The second exhaust duct cleaning mode of 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 water amount supplied to the inside of the outer tube 3 is large, the water level in the first exhaust duct 60 increases as shown in fig. 11 (a). In this state, the drum 5 rotates to flush the inner peripheral surface of the first exhaust duct 60 without forming a strong water flow in the first exhaust duct 60, thereby collecting dust removed from the inner peripheral surface of the first exhaust duct 60.
When the second exhaust duct cleaning mode of the exhaust duct cleaning mode 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 cylinder 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 tube 3; and a first exhaust duct 60 that communicates with the inside of the outer tube 3 through an inflow port 61 formed in the upper peripheral wall of the outer tube 3, and the operation mode includes an exhaust duct cleaning mode in which the inside of the first exhaust duct 60 is cleaned.
With such a configuration, even when dust and the like contained in the air flowing from the outer tube 3 into the first exhaust duct 60 accumulate 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 flowing water from the outer tube 3 into the first exhaust duct 60 by operating in the exhaust duct cleaning mode. Therefore, maintainability improves, and the necessity of cleaning the inside of the first exhaust duct 60 by manual work decreases. This can suppress occurrence of a decrease in drying performance due to a decrease in exhaust gas amount caused by adhesion of dust or the like to the first exhaust duct 60, a failure due to a decrease in exhaust gas air volume, or the like, and can reduce the number of times of cleaning the inside of the first exhaust duct 60 by manual work.
In the washing and drying integrated machine 1 of the present embodiment, the inflow port 61 is disposed at a position eccentric to the left direction with respect to the rotation axis of the drum 5 in front view, the first exhaust duct 60 as the exhaust duct is a hollow box-shaped member disposed so as to extend from the front side toward the rear side and one end side thereof is opposed to the inflow port 61, and in the exhaust duct cleaning mode, the drum 5 is rotationally driven so that the upper end portion of the drum 5 moves from the side not eccentric to the inflow port 61 toward the side eccentric to the inflow port 61 in the vicinity of the upper peripheral surface wall of the outer cylinder 3.
With such a configuration, water in the outer tube 3 is likely to be accumulated in the first exhaust duct 60 after flowing into the first exhaust duct 60. Therefore, in the exhaust duct cleaning mode, dust and the like accumulated in a wide area on the inner peripheral surface of the first exhaust duct 60 can be removed by the water flowing from the outer tube 3 into the first exhaust duct 60.
In the washing and drying integrated 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 rotational speed greater than that in the drum washing mode, and the amount of water supplied into the outer tub 3 is greater than the amount of water supplied into the outer tub 3 in the drum washing mode.
With such a configuration, in the exhaust duct cleaning mode, the amount of water supplied into the outer tube 3 is larger than that in the drum cleaning mode, and the rotational speed of the drum 5 is larger than that in the drum cleaning mode, so that a large amount of water flows from the outer tube 3 into the first exhaust duct 60, and dust and the like accumulated on the inner peripheral surface of the first exhaust duct 60 can be effectively removed.
In the washing and drying integrated machine 1 of the present embodiment, the exhaust duct washing mode includes: the first exhaust duct cleaning mode is a mode in which the amount of water supplied into the outer tube 3 is a first amount of water (water level 6 °); and a second exhaust duct cleaning mode, which is performed after the first exhaust duct cleaning mode, and which is a mode in which the amount of water supplied into the outer tube 3 is a second amount of water (9 degrees in water level) that is larger than the first amount of water.
When such a configuration is adopted, in the exhaust duct cleaning mode, first, a strong water flow is generated in the first exhaust duct 60 in a state where the water level in the first exhaust duct 60 is low, so that dust and the like accumulated on the inner peripheral surface of the first exhaust duct 60 are removed, and then, a gentle water flow is generated in the first exhaust duct 60 in a state where the water level in the first exhaust duct 60 is high, so that dust and the like removed from the inner peripheral surface of the first exhaust duct 60 are washed away.
The embodiments of the present invention have been described above, but the configuration of the present embodiment is not limited to the above configuration, and various modifications are possible.
For example, in the above embodiment, the explanation has been made on the case where the inflow port 61 is disposed at a position eccentric in the left direction with respect to the rotation axis of the drum 5 in the front view in the washing and drying integrated machine 1, but the present invention is not limited thereto. In the washing and drying integrated machine 1, the inflow port 61 may be disposed at a position eccentric in the rightward direction with respect to the rotation axis of the drum 5 in front view.
In the above embodiment, the first exhaust duct 60 of the washing and drying integrated machine 1 is described as a hollow box-shaped member that is disposed to extend from the front side toward the rear side and the rear side thereof is opposed to the inflow port 61, but the present invention is not limited thereto. In the washing and drying integrated machine 1, the first exhaust duct 60 may be a hollow box-shaped member that is disposed so as to extend from the front side toward the rear side, and the front side thereof faces the inflow port 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 around the right rotational direction. In addition, in the exhaust duct cleaning mode, the drum 5 may be rotationally driven to alternately repeat the left rotation direction and the right rotation direction.
In the above embodiment, the exhaust pipe cleaning mode is implemented by two operations, that is, the first exhaust pipe cleaning mode and the second exhaust pipe cleaning mode implemented after the first exhaust pipe cleaning mode, but is not limited thereto. The exhaust duct cleaning mode may be implemented by one operation, or may be implemented by three or more operations. Further, although examples of the operation times related to the first exhaust pipe cleaning mode and the second exhaust pipe cleaning mode of the exhaust pipe cleaning modes are shown, these operation times are arbitrary.
In the above embodiment, the exhaust duct cleaning mode is started when the door 11 is closed after the drum cleaning button 81 is operated for 10 seconds with the door 11 opened, but the present invention is not limited thereto. The operation for starting the exhaust pipe cleaning mode and the like are arbitrary.
In the above-described embodiment, the operation mode has the drum washing mode, but the present invention can be applied to a washing and drying integrated machine in which the operation mode does not have the drum washing mode.
Other structures may be variously modified within a range not departing from the gist of the present invention.
