Description

washing and drying machine

technical field

The invention relates to an integrated washing and drying machine.

Background technique

Among the existing all-in-one washing and drying machines, there is the following all-in-one washing and drying machine, which has: an outer cylinder; a substantially cylindrical drum disposed in the outer cylinder to rotate freely; an air suction duct disposed on the upper right side of the peripheral wall of the outer cylinder part; and an exhaust duct disposed on the upper left portion of the peripheral wall of the outer cylinder (for example, refer to Patent Document 1). The exhaust duct has: a first exhaust duct communicating with the inside of the outer cylinder through an opening formed in the peripheral wall of the outer cylinder; communicate with the first exhaust pipe. A fan and a filter are arranged inside the second exhaust duct.

During the drying process, by driving the fan, the air for drying the laundry is supplied from the suction duct into the outer tub, and the air in the outer tub is exhausted from the exhaust duct. Dust and lint (lint, fluff, etc.) contained in the air flowing in the exhaust duct are captured by the filter.

In the conventional washer-dryer, the fan is usually driven at a predetermined rotational speed during the drying process so that the flow of air supplied into the outer cylinder is kept substantially constant. However, when dust or the like flowing into the exhaust duct during the drying process is captured by the filter and clogs the filter, the resistance of the filter increases. In this way, although the fan is driven at a predetermined speed, the flow of air supplied to the outer cylinder will still be reduced, and the drying efficiency of the drying process will be significantly reduced.

It should be noted that, not only when the filter is clogged with dust or the like and the flow rate of air supplied to the outer cylinder is reduced, but also when the flow rate of air supplied to the outer cylinder is reduced for some reason, the same applies. There arises a problem that the drying efficiency in the drying process is significantly lowered.

An air intake duct inlet 54 is formed at the front lower end of the second air intake duct 53 to communicate with the outside of the machine. A circular air intake duct outlet 55 is formed at the lower end of the other end of the second air intake duct 53 on the side opposite to the side where the air intake duct inlet 54 is formed. The suction duct inlet 52 of the first suction duct 50 and the suction duct outlet 55 of the second suction duct 53 are connected by a suction duct connection pipe 56 .

A heater 57 is disposed inside the second air intake duct 50 . The heater 57 is, for example, a gas heater that burns gas supplied from an external gas supply path (not shown) and heats the surrounding air with the combustion heat. The air in the two suction pipes 53. That is, during the drying process, heated air for drying laundry is generated by heating of the heater 57 .

On the upper left portion of the peripheral wall of the outer cylinder 3, as shown in FIG. The exhaust duct 60 has a first exhaust duct 61 , a second exhaust duct 63 , and an exhaust duct connection pipe 65 connecting the first exhaust duct 61 and the second exhaust duct 63 .

The first exhaust duct 61 is a hollow box-shaped member that includes a front, a back, an upper surface, a left side, and a lower surface formed of the peripheral wall of the outer cylinder 3 and extends in the front-rear direction. A substantially rectangular opening 60 a is formed at the rear of the lower surface (outer peripheral surface of the peripheral wall of the outer cylinder 3 ) of the first exhaust duct 61 through which the first exhaust duct 61 communicates with the outer cylinder 3 . In addition, a circular exhaust duct outlet 62 is formed on the upper surface of the first exhaust duct 61 as shown in FIG. 1 .

The second exhaust duct 63 is provided above the first exhaust duct 61 and is a substantially rectangular parallelepiped hollow box-shaped member extending in the front-rear direction. The second exhaust duct 63 is fixed to the box body 2 by a fixing member not shown, and at the lower end near the front of the second exhaust duct 63, as shown in FIG. . The exhaust duct outlet 62 of the first exhaust duct 61 and the communication hole 64 of the second exhaust duct 63 are connected by an exhaust duct connecting pipe 65 .

In addition, an exhaust duct outlet 66 is formed at the upper end portion of the other end of the second exhaust duct 63 on the opposite side to the side where the communication hole 64 is formed. The exhaust duct outlet 66 protrudes outward from the upper surface of the casing 2, and the outer cylinder 3 and the outside of the machine pass through the exhaust duct 60 including the first exhaust duct 61, the exhaust duct connecting pipe 65 and the second exhaust duct 63. connected.

A fan 67 is arranged inside the second exhaust duct 63 . The fan 67 is driven, for example, during the drying process, so that the air in the drum 5 and the outer cylinder 3 flows out of the machine through the exhaust duct 60 from the exhaust duct outlet 66 .

In addition, as shown in FIG. 1 , a filter 68 is provided between the fan 67 and the communication hole 64 inside the second exhaust duct 63 . The filter 68 is inclined upward from the front side toward the rear side to divide the interior of the second exhaust duct 63 into the communication hole 64 side and the fan 67 side, and captures dust and lint contained in the air from the communication hole 64. (thread scraps, fluff, etc.).

Inside the second exhaust duct 63 , as shown in FIG. 4( a ), the lower end portion of the filter 68 is supported by a filter support stand 68 a. The filter support base 68a has a vertical portion 68a ₁ extending in the vertical direction on the side closer to the fan 67 than the communication hole 64 , and a horizontal portion 68a ₂ extending from the upper end of the vertical portion 68a ₁ in the direction opposite to the fan 67 . The front end of the horizontal portion 68a ₂ supports the lower end portion of the filter 68 above the communication hole 64 . Therefore, the horizontal portion 68a ₂ is arranged to cover a part of the communication hole 64 , and the vicinity of the lower end of the filter 68 is arranged to overlap the communication hole 64 in plan view.

As shown in FIG. 4( a ) and FIG. 4( b ), a moving member 80 is arranged around the communication hole 64 inside the second exhaust duct 63 . The moving member 80 has a cover member 81 and a support member 82 that supports the cover member 81 . The supporting member 82 is installed substantially parallel to the upper surface of the cover member 81 . The cover member 81 is a member capable of taking a closed position for closing the communication hole 64 . The supporting member 82 is provided so as to be able to swing in the vertical direction about a fulcrum 82a arranged near the vertical portion 68a ₁ of the filter support base 68a as a fulcrum. That is, when the support member 82 swings about the fulcrum 82a, the cover member 81 moves in the up-down direction.

As shown in FIG. 5 , when the cover member 81 is located at the lowermost position, the cover member 81 is arranged at a blocking position for blocking the communicating hole 64 . On the other hand, when the cover member 81 is located at the maximum opening position farthest upward from the closed position, the cover member 81 is arranged so that the upper surface of the cover member 81 contacts the front end of the horizontal portion _68a2 of the filter support stand 68a. Location. The cover member 81 is movable between the lowermost position and the maximum opening position, and the distance from the closed position changes according to the position.

The supporting member 82 is attached so as to be able to swing freely with respect to the fulcrum 82a, and when the fan 67 is not driven, the cover member 81 is arranged at the lowest position by its own weight. For example, during washing, since the fan 67 is stopped and no wind is generated, the cover member 81 is arranged at the closed position. Therefore, during washing, even if water is splashed toward the communication hole 64 of the second exhaust duct 63 due to the high-speed rotation of the drum 5, the communication hole 64 will be blocked by the cover member 81, and the water will hit the cover member. 81 without entering into the second exhaust pipe 63. Therefore, water does not reach the filter 68, and the filter 68 does not get wet.

In addition, the rubber packing 83 is attached to the outer peripheral part of the lower surface of the cover member 81 over the whole circumference. Therefore, when the cover member 81 is located at the closed position, the sealing performance between the outer peripheral portion of the cover member 81 and the peripheral portion of the communication hole 64 is improved.

During the drying operation, the cover member 81 is sucked toward the filter 68 by wind generated by the fan 67, and the communication hole 64 is opened. At this time, since the cover member 81 does not block the air passage, the drying air can pass normally. During the drying process, which position the cover member 81 is disposed between the lowermost position and the maximum opening position is determined according to the flow rate of air flowing into the second exhaust duct 63 through the communication hole 64 .

A position switch 85 for switching the ON state/OFF state according to the position of the moving member 80 is attached to the fulcrum 82a. When the support member 82 is swung upward so that the cover member 81 is arranged at the maximum opening position, the position switch 85 is turned on, and the cover member 81 is arranged below the maximum opening position on the support member 82 . In the case of swinging upward, the position switch 85 is turned off. In this embodiment, the position switch 85 is used to detect whether the cover member 81 is located at the maximum opening position.

As described above, when the fan 67 is driven during the drying process, the cover member 81 is pulled by the negative pressure of the fan 67 to move upward. At this time, the higher the rotation speed of the fan 67 is, the more the cover member 81 moves away from the lowermost position. According to the opening angle of the cover member 81 , the effective cross-sectional area of the drying air passage changes from fully closed to maximum open.

In the washer-dryer 1 of this embodiment, the rotation of the fan 67 is controlled to increase or decrease the air volume: by driving the fan 67 at a predetermined speed or more during the drying process, the air pressure of the drying air of the fan 67 The opening angle of the lid member 81 that is sucked upward, rotated upward, and opened is equal to or greater than a certain value, that is, the lid member 81 is disposed at the maximum opening position.

FIG. 6 is a control block diagram of the all-in-one washing and drying machine 1 . The control unit 100 of the washer-dryer 1 is, for example, composed of a microcomputer as shown in FIG. 6 , and is provided with: a central processing unit (CPU); And a random access memory (RAM), which temporarily stores data and the like used when executing the above programs. The operation of the washer-dryer 1 is controlled by the control unit 100 . The position switch 85, the fan 67, and the filter clogging display part 2a are connected to the control part 100. As shown in FIG.

In the all-in-one washer-dryer 1 of this embodiment, a predetermined rotation speed is preset as the rotation speed of the fan 67 in the drying process. Therefore, at the beginning of the drying process, it is generally set that when the fan 67 is driven at a predetermined speed, the cover member 81 is pulled by the negative pressure of the fan speed, and the cover member 81 is disposed at the maximum opening position. It should be noted that the above-mentioned setting is performed in a state where dust and the like are hardly clogged in the filter 68 (a state where filter clogging does not occur).

The control section 100 senses whether the cover member 81 is located at or below the maximum opening position according to which of the position switch 85 is on or off.

The point of sensing whether or not the cover member 81 is located at the maximum opening position will be described. In the all-in-one washer-dryer 1, when the filter 68 is partially clogged with dust or the like due to the drying operation for a long time, the resistance of the filter 68 increases. The air flow of the air duct 60 is also reduced. In this way, the negative pressure pulling the cover member 81 becomes smaller, and the cover member 81 moves below the maximum opening position. Therefore, the control portion 100 determines whether filter clogging has occurred in the filter 68 by sensing whether the cover member 81 is located at the maximum opening position.

When the cover member 81 is located below the maximum opening position (when filter clogging occurs in the filter 68), the control unit 100 controls the fan 67 so that the rotational speed of the fan 67 is increased by a preset predetermined amount (for example, 50 rpm). speed. In this embodiment, after the fan 67 is controlled to increase the rotation speed by a predetermined amount, it is determined whether the cover member 81 is at the maximum opening position, and then the rotation speed of the fan 67 is gradually increased by a predetermined amount until it is determined that the cover member 81 is at the maximum opening position. It is controlled in the way of the maximum opening position.

The filter clogging display part 2a is provided in the front surface of the housing|casing 2, For example, LED etc. are included. The filter clogging display part 2 a lights up when the filter 68 is clogged with dust or the like, making it difficult for air to pass through, and is used to notify that the filter clogging has occurred. In this embodiment, the control unit 100 determines that filter clogging has occurred when the lid member 81 is below the maximum opening position after starting the drying process, and lights the filter clogging display unit 2a.

The control method of the rotation speed of the fan 67 in a drying process is demonstrated based on FIG. 7. FIG. FIG. 7 is a flowchart illustrating a method of controlling the rotational speed of the fan 67 during the drying process.

In step S1, the control unit 100 drives the fan 67 according to a predetermined rotation speed, and starts the drying process. After that, proceed to step S2.

In step S2, the control unit 100 determines whether or not the cover member 81 is located at the maximum opening position. When the control part 100 determines that the cover member 81 is located in the maximum opening position, it returns to step S3. When the control part 100 judges that the cover member 81 is not located in the maximum opening position, it progresses to step S4.

In step S3, the control unit 100 determines whether or not a predetermined time preset as the duration of the drying process has elapsed. When the control unit 100 determines that the predetermined time has elapsed, the process ends. When the control part 100 judges that predetermined time has not passed, it returns to step S2.

In step S4, since the cover member 81 is not located at the maximum opening position, the control part 100 turns on the filter clogging display part 2a. After that, proceed to step S5.

In this embodiment, when the control unit 100 determines that the cover member 81 is not at the maximum opening position at the beginning after starting the drying process, the control unit 100 lights the filter clogging display part 2a, and then continues to turn on the filter. The display part 2a is blocked until the drying process is completed.

In step S5, the control unit 100 increases the rotational speed of the fan 67 by a predetermined amount. After that, proceed to step S6.

In step S6, the control part 100 determines whether the cover member 81 is located in the maximum opening position. When the control part 100 determines that the cover member 81 is located in the maximum opening position, it progresses to step S3. When the control part 100 judges that the cover member 81 is not located in the maximum opening position, it returns to step S5.

The integrated washer-dryer 1 of the present embodiment is provided with: an outer cylinder 3 for accommodating a substantially cylindrical drum 5 in a freely rotatable manner; The air flowing out of 60a passes through; the fan 67 generates an air flow passing through the exhaust duct 60; the moving member 80 moves according to the air flow rate passing through the exhaust duct 60; and the control part 100, as a control unit, The position of 80 controls the rotating speed of fan 67.

When such a structure is adopted, even if the air flow rate supplied to the outer tub 3 is reduced for some reason during the drying process, the rotation speed of the fan 67 is controlled based on the position of the moving member 80 that moves according to the air flow rate. Therefore, it is also possible to prevent the drying efficiency of the drying process from being significantly reduced due to the reduction of the air flow rate supplied to the outer cylinder 3 .

In the washer-dryer 1 of this embodiment, the exhaust duct 60 has: a first exhaust duct 61 communicating with the outer tube 3 through the opening 60a; and a second exhaust duct 63 arranged in the first exhaust duct 61, the second exhaust duct 63 communicates with the first exhaust duct 61 through the communication hole 64 formed on its lower surface, and the moving member 80 is equipped with: a cover member 81, which can be used as a block to block the communication hole 64. position; and a support member 82 that supports the cover member 81 so that the distance between the cover member 81 and the closed position changes when the communication hole 64 is opened.

When such a structure is adopted, since the cover member 81 blocks the communication hole 64 formed on the lower surface of the second exhaust duct 63 when the fan 67 is stopped, it is possible to prevent the above-mentioned communication hole 64 during the washing process and the rinsing process. Water entering the second exhaust duct 63 through the hole 64 adheres to the filter 68 .

In the integrated washing and drying machine 1 of this embodiment, it is provided with: a filter 68 disposed in the exhaust duct 60, the air flowing through the exhaust duct 60 passes through the filter, and the moving member 80 Blocked state to move.

When such a structure is adopted, since the moving member 80 moves according to the clogged state of the filter 68 in the exhaust duct 60, even when the flow rate of the air supplied to the outer tube 3 decreases due to the clogged filter 68 It can also prevent the drying efficiency of the drying process from being significantly reduced due to the reduction of the air flow rate supplied to the outer cylinder 3 .

The washer-dryer 1 according to this embodiment includes a filter clogging display unit 2 a as notification means for notifying filter clogging, and the control unit 100 controls the filter clogging display unit 2 a based on the position of the moving member 80 .

With such a configuration, when the filter 68 is clogged, the filter clogging display unit 2a can be used to notify that the filter clogging has occurred.

In the washer-dryer 1 of this embodiment, the filter 68 is arranged so that at least a part thereof overlaps the communicating hole 64 in a plan view.

With such a configuration, the area of the filter 68 can be increased compared to a case where the filter 68 is arranged so as not to overlap the communication hole 64 in plan view. Therefore, it is possible to suppress a reduction in the flow rate of air passing through the exhaust duct 60 due to clogging of the filter 68 .

As mentioned above, although embodiment of this invention was described, the structure of this embodiment is not limited to the said structure, Various deformation|transformation is possible.

For example, in the above-described embodiment, the exhaust duct 60 has the first exhaust duct 61 , the second exhaust duct 63 , and the exhaust duct connecting pipe 65 , but the structure of the exhaust duct 60 is arbitrary.

In the above-mentioned embodiment, the moving member 80 has the cover member 81 and the support member 82, but the structure of the moving member 80 is arbitrary. For example, the moving member 80 does not need to include the cover member 81 that can be set to the closing position for closing the communication hole 64 . It should be noted that, when the moving member 80 includes the cover member 81 that can be set to the closing position for closing the communication hole 64, the gas of coin laundromats such as coin laundromats that have a lint filter installed in the exhaust air path In an all-in-one clothes washer-dryer, even when the centrifugal force washing is performed at a slightly faster speed to make the quilt stick to the washing tub, a large amount of washing water will be rolled up, and the rolled up water It will enter the exhaust air duct side and prevent water from adhering to the lint filter. Thereby, there will be no problems that cleaning is difficult if the lint filter is wet, and that dust trapped by drying will prevent cleaning if agglomerated.

In the above-mentioned embodiment, the case where the flow rate of the air passing through the exhaust duct 60 decreases due to filter clogging has been described with respect to the moving member 80 , but the present invention is not limited thereto. The present invention can also be applied to situations where the flow of air through the exhaust duct 60 is reduced due to reasons other than filter clogging.

In the above embodiment, the filter clogging indicator 2a is turned on when it is determined that the filter clogging has occurred when the cover member 81 is not located at the maximum opening position and the filter clogging indicator 2a is notified that the filter clogging has occurred. Circumstances are described, but not limited to. For example, when the cover member 81 is separated from the maximum opening position by a predetermined distance, it is determined that filter clogging has occurred, and the filter clogging display part 2a may be turned on.

In the above-mentioned embodiment, the case where the filter clogging display part 2a which notifies occurrence of filter clogging was provided was demonstrated, but it is not limited to this. The all-in-one washer-dryer 1 of the present invention may not have a notification means for notifying that the filter clogging has occurred.

In the above-described embodiment, the filter clogging display portion 2a is provided as the notification means for notifying that the filter clogging has occurred, but the configuration of the notification means is arbitrary. For example, the notification unit may notify that the filter is clogged by sound.

In the above-mentioned embodiment, the case where the filter 68 is arranged so that at least a part thereof overlaps the communication hole 64 in a planar view has been described, but the present invention is not limited thereto. For example, the entire filter 68 may be disposed at a position different from that of the communication hole 64 in plan view.

In the above embodiment, there is the position switch 85 that switches the ON state/OFF state according to the position of the moving member 80, and the control unit 100 determines whether the position switch 85 is in the ON state or the OFF state. Whether it is located at the maximum opening position or whether the cover member 81 is located below the maximum opening position, but not limited thereto. For example, instead of the position switch 85 , an angle sensor that detects the angle of the supporting member 82 may be attached to the fulcrum 82 a. This angle sensor can detect the opening angle of the lid member 81 (the angle at which the lid member 81 moves relative to the closed position).

In the above-described embodiment, when the cover member 81 is not at the maximum opening position during the drying process, the rotation speed of the fan 67 is controlled to increase by a predetermined amount, and thereafter, the rotation speed of the fan 67 is gradually increased by a predetermined amount until Control is performed so as to determine that the cover member 81 is located at the maximum opening position, but the control method when increasing the number of rotations of the fan 67 is arbitrary.

For example, in the case of having an angle sensor for detecting the angle of the support member 82 as described above, the control unit 100 may control the rotation speed of the fan 67 in such a manner as to detect the degree of decrease in the opening angle of the cover member 81 (opening angle of the cover member 81 angle is smaller than the case at the maximum opening position), increase the rotational speed corresponding to the decrease in the opening angle of the cover member 81, and arrange the cover member 81 at the maximum opening position. That is, the control unit 100 determines that the clogged state of the filter 68 is not so bad when the degree of decrease in the opening angle of the cover member 81 is small, whereas when the degree of decrease in the opening of the cover member 81 is large, It was judged that the clogging state of the filter 68 was extremely bad. In this case, as to how much the rotation speed of the fan 67 is increased according to the degree of decrease in the opening angle of the cover member 81 so that the cover member 81 is disposed at the maximum opening position, the position of the fan 67 at this time has been obtained in advance through experiments or the like. The relationship between the rotation speed, the decrease degree of the opening angle of the cover member 81 and the increase amount of the rotation speed of the fan 67 and the like are stored in the control unit 100 .

In the above-mentioned embodiment, the case where the rubber packing 83 is attached to the outer peripheral portion of the lower surface of the cover member 81 has been described, but the present invention is not limited thereto. For example, when the rubber seal 83 is attached to the peripheral portion of the communication hole 64 , the sealing performance between the outer peripheral portion of the cover member 81 and the peripheral portion of the communication hole 64 is also improved. In addition, the rubber packing 83 which improves the sealing performance between the outer peripheral part of the cover member 81 and the peripheral part of the communication hole 64 may not be provided.

In the above embodiment, when the control unit 100 judges that the cover member 81 is not at the maximum opening position after the drying process starts, the control unit 100 turns on the filter clogging display unit 2a and then continues to turn on the filter. The case where the display part 2a is blocked until the drying process is finished has been described, but it is not limited thereto. For example, the control unit 100 may continue to turn on the filter clogging display unit 2a even after the drying process is completed.

Various modifications can be made to other structures without departing from the gist of the present invention.
