Description

  The present invention relates to a washing / drying machine that dries mainly washed clothes.

  In the conventional drying operation of this type of washing and drying machine, the outside air sucked by the electric blower is heated by a heating element such as a heater, and the obtained warm air is applied to the clothes in the washing tub so that steam from the clothes is discharged. The clothes are dried by discharging the contained air to the outside, but if the outside air sucked contains floating dust, it enters the washing dryer and condenses the heating elements and vapors. A filter for collecting dust is detachably provided because it is attached to a cooling device and further an electric blower or the like to hinder its function.

  If dust accumulates on the filter, the intrusion of outside air is hindered, the drying efficiency is lowered, and the electric blower is adversely affected. Therefore, it is necessary to periodically clean the filter. In this case, if the filter is lost, forgotten to be installed, or installed halfway, suspended dust will enter the main body. To prevent this, downstream of the removable main filter (primary filter body) On the side, a backup filter (secondary filter body) is fixed to the main body (for example, see Patent Document 1).

  FIG. 10 is a cross-sectional view showing a schematic configuration of the washing and drying machine described in Patent Document 1, and FIG. 11 is a perspective view of a fan casing portion of the washing and drying machine.

  10 and 11, a conventional washing and drying machine has a water tub 2 slidably disposed in an outer box 1, a rotatable wing 3 disposed at the bottom in the water tub 2, and a peripheral wall. A washing and dewatering tub 4 having a large number of dewatering holes 5 is provided. 6 is a balancer attached to the upper part of the washing / dehydrating tub 4, and 7 is a motor for rotating the washing / dehydrating tub 4 and the rotary blade 3. A top panel 9 having a lid 8 is attached to the opening at the top of the outer box 1.

  An opening 10 for taking in outside air during a drying operation is provided on the upper side of the outer box 1, and a fan casing 12 containing a blower fan 11 such as a sirocco fan is installed in the opening 10, and the fan casing 12 is formed. A secondary filter body 14 composed of a net-like secondary filter 14 a is fixed to the outside air inlet 13.

  The outer side of the secondary filter body 14 holds the primary filter 15a and the outer periphery of the primary filter 15a, and is detachably attached to guide portions 12a provided on both sides of the outside air intake port 13 of the fan casing 12. A primary filter body 15 including a primary frame body 15b is disposed. Further, a brush member 15 c that is in sliding contact with the secondary filter body 14 is provided inside the primary filter body 15.

  A duct 16 is provided between the discharge side of the fan casing 12 and the water tank 2, and a heater 17 for heating the sucked outside air is disposed in the duct 16.

  An inner lid 18 is provided at the upper opening of the water tank 2, and an outlet 20 having a filter 19 is formed in the inner lid 18.

  Further, an exhaust port 21 is provided in the top panel 9 at a position above the discharge port 20.

  The operation of the conventional washing dryer configured as described above during the drying operation is as follows.

  The blower fan 11 is actuated to take outside air from the opening 10 formed in the outer box 1 into the fan casing 12 through the primary filter body 15 and the secondary filter body 14, and heated by the heater 17. The wind is brought into contact with the laundry 22 in the washing and dewatering tub 4 through the duct 16 to evaporate moisture contained in the laundry 22. Then, the moisture-containing air is discharged to the outside through the filter 19 provided at the discharge port 20 and the exhaust port 21.

  When the outside air taken in from the opening 10 passes through the primary filter body 15 and the secondary filter body 14, dust and dust contained in the outside air are collected. Therefore, clean air from which dust and dirt have been removed is supplied to the washing and dewatering tub 4, and dust and dirt do not adhere to the blower fan 11 and the heater 17. Moreover, since the secondary filter body 14 is directly attached to the fan casing 12, even if the primary filter body 15 is forgotten to be attached to the opening 10, dust and dust do not enter the inside.

  Moreover, if dust accumulates on the primary filter body 15, it can be lifted upward and easily removed for cleaning. Further, when the primary filter body 15 is pulled out, the secondary filter body 14 is cleaned by the brush member 15c provided on the inner surface of the primary filter body 15, which is very convenient.

  FIG. 12 shows another example of a conventional washing and drying machine, and is a cross-sectional view of a hot air circulation path through which hot air for drying clothes is dried during a drying operation (see, for example, Patent Document 2).

  In FIG. 12, a heater 32 for heating the circulating air is provided in a part of the hot air circulation path 31, and the secondary filter body 34 and the hot air circulation path 31 are inserted into and removed from the heater 32 upstream of the heater 32. The possible primary filter body 33 is provided in order, and the brush member 35 that contacts the upstream surface of the secondary filter body 34 when the primary filter body 33 is inserted and removed from the hot air circulation path 31 is provided as the primary filter body. 33 is provided at the rear end of the downstream surface of 33.

  The operation of the conventional washing and drying machine configured as described above is as follows. The air heated by the heater 32 is blown to clothing stored in a drying chamber (not shown) by an electric blower (not shown), and the air containing the steam generated from the clothing flows into a condenser (not shown) where Is condensed and recovered, and dry air passes through the hot air circulation path 31 and reaches the primary filter body 33. Then, relatively large dust is captured by the primary filter body 33, fine dust that has passed through the primary filter body 33 is captured by the secondary filter body 34, and the clean air is heated again by the heater 32, The clothes are dried while repeating the operation of being sent to the drying room.

When the primary filter body 33 is clogged, the primary filter body 33 is removed from the hot air circulation path 31 and cleaned using a brush or the like. After cleaning, the primary filter body 33 is moved to the hot air circulation path 31. Try to insert. Further, when the primary filter body 33 is inserted into and removed from the hot air circulation path 31, the brush member 35 provided on the primary filter body 33 moves while contacting the upstream surface of the secondary filter body 34, and the secondary filter The dust adhering to the body 34 is removed, the removed dust falls on the primary filter body 33, and the secondary filter body 34 is automatically cleaned.

Installed and transmission gear And a shaft body that is integrally formed with an engagement gear that is engagably engaged with the transmission gear and that moves in conjunction with the opening / closing operation of the lid. Since the filter body is fixed inside the main body and is not visible from the outside, the degree of dirt is difficult to understand, and it cannot be confirmed without removing the primary filter body from the main body, but the shaft body moves in conjunction with the opening and closing operation of the lid. Thus, it is convenient because the dust removal body can be driven via the transmission gear engaged with the engagement gear of the shaft body, and the secondary filter body can be automatically removed. In particular, since the lid always opens and closes when the washing / drying machine is used, the secondary filter body is always fresh.

  The washing / drying machine according to the present invention is easy to use because the secondary filter body can be easily cleaned without removing the primary filter body.

  In a first aspect of the present invention, a substantially rectangular parallelepiped body having an outside air intake and an air outlet has an inner tub for storing laundry, an outer tub for rotatably storing the inner tub, and an outside air sucked from the outside air intake. And an electric blower that blows air into the inner tank and exhausts it from the exhaust port, and a collection filter body that is provided at the outside air intake port and collects dust, and the collection filter body is a secondary filter body And a primary filter body that faces the secondary filter body on the upstream side of the secondary filter body and is detachably attached to the main body, and the secondary filter body is fixed to the main body.

An electric blower 56 that passes through the passage port 44a and exhausts air from the exhaust port 41b, and a heater 57 that heats the air sucked by the electric blower 56 to a predetermined temperature are arranged.

  58 is a temperature / humidity sensor that catches the temperature and humidity in the inner tub 45, and a controller (not shown) that controls the operation of the heater 57 and the electric blower 56 based on the temperature / humidity data detected by the temperature / humidity sensor 58. Z) is also decorated.

  The collection filter body 54 includes a secondary filter body 60 and a primary filter body 61 that is detachably attached to the main body 40 so as to face the secondary filter body 60 on the upstream side of the secondary filter body 60. It is configured.

  As shown in FIG. 3, the secondary filter body 60 is fixed to the main body 40 and has a substantially flat secondary frame 60a, and a substantially circular shape whose outer periphery is supported and fixed by the secondary frame 60a. A secondary filter 60b and a dust remover 62 that removes dust adhering to the upstream surface of the secondary filter 60b are configured. The dust remover 62 is rotatably supported at the center of the secondary filter 60b and rotates while contacting the upstream surface of the secondary filter 60b to remove dust attached to the secondary filter 60b.

The frame 64 and a primary filter 65 fixed to the other end surface of the primary frame 64 and collecting dust contained in the sucked outside air.

  The size of the primary filter 65 is formed to be larger than the planar area of the secondary filter 60b as a whole, and the dust removed from the secondary filter 60b by the dust remover 62 is securely stored in the dust storage chamber 64b. can do.

  A guide rib 64c that can be inserted into a guide groove 53a formed to face the outside air inlet 53 of the main body 40 is provided on the outer surface of the primary frame body 64, and the primary filter body 61 is detachably attached to the main body 40. It has come to be supported.

  The handle 63 includes a handle portion 63a and an engagement gear 63b that is engagably engaged with the transmission gear 62b, and includes a shaft body 63c that is coupled to the handle portion 63a, and the top of the primary frame 64. It is supported by a bearing 64d that is suspended from the surface so as to be movable up and down.

  In the middle of the longitudinal direction of the shaft body 63c, a stopper 63d is provided in a direction orthogonal to the longitudinal direction. On the other hand, the bearing 64d is formed with a slit 64g that allows the stopper 63d of the shaft body 63c to move. An elastic body 66 is arranged on the outer periphery of the bearing 64d between the top surface of the primary frame body 64 and the stopper 63d, and the shaft body 63c, that is, the handle 63 is always on the lower side, that is, on the primary frame body 64 side. It is energized by the energizing force. In this embodiment, the handle 63 is set to the lowest position by the urging force of the elastic body 66, and the stopper 63d of the shaft body 63c is set in the vicinity of the exit of the slit 64g and not to protrude from the slit 64g. is doing. If the distance between the upper surface of the stopper 63d and the upper end of the slit 64g is L at the position where the handle 63 is lowered, this distance L is an allowable moving distance in the bearing 64d of the shaft body 63c. That is, when the handle 63 is lifted upward by a distance L, the stopper 63d comes into contact with the upper end of the slit 64g provided in the bearing 64d, and further upward movement of the handle 63 is restricted. Further, in this embodiment, while the handle 63 is moved upward by the distance L, the transmission gear 62b with which the engaging gear 63b of the shaft 63c is engaged is at least one turn, that is, the dust removing body 62 is at least one. It is designed to rotate after rotation.

  Further, in the present embodiment, the shaft body that prevents the shaft body 63c from wobbling and the engagement gear 63b of the shaft body 63c from separating from the transmission gear 62b of the dust removing body 62 at the portion provided with the slit 64g of the bearing 64d. The restriction portion 64h is used.

  A dust accumulation portion 64e is provided below the primary frame 64, and its lower surface has an inclined surface so that dust attached to the upstream surface of the secondary filter 60b can be securely stored by the rotation of the dust remover 62. The lower inclined surface 64f is formed, and further, the upstream side (A portion) is constituted by a part of the primary frame body 64 (the primary filter 65 is not disposed), so that the outside air cannot pass through. In addition, the dust from the secondary filter 60b does not reattach to the secondary filter 60b due to the external airflow. Further, by forming the outside air passage narrow hole constituting the secondary filter 60b smaller than the outside air passage narrow hole constituting the primary filter 65, the dust passing through the primary filter 65 is surely captured. Can be collected.

  The operation and action of the washing and drying machine in the present embodiment configured as described above are as follows. The operations and actions during the operations of washing, dewatering, rinsing, and dewatering are the same as those of the conventional washing and drying machine, and therefore the description thereof will be omitted. In particular, the operation during the drying process will be described.

  The clothing 67 stored in the inner tub 45 is washed and rinsed by the rotational force of the rotary blade 46, dehydrated by the high-speed rotation of the inner tub 45, and then moves to a drying process for the clothing 67.

  In the drying process, the heater 57 is energized and generates heat at the same time as the operation of the electric blower 56 is started. As a result, the outside air containing dust is cleaned by the collection filter body 54, becomes warm air in the air blowing path 55, enters the inner tank 45, dries the clothing 67, and vapors from the clothing 67. And is discharged to the outside through the exhaust port 41b through the passage port 44a.

  This drying process is repeated until the temperature and humidity sensor 58 detects a predetermined temperature and humidity, and then the operation is stopped. If such a drying process is repeated several times, dust accumulates on the collection filter body 54, obstructs intrusion of outside air, and lowers the drying efficiency. Therefore, the collection filter body 54 is periodically cleaned. Need to do. At this time, since the primary filter body 61 is provided above the main body 40 and in the vicinity of the operation section 42 to prevent the primary filter body 61 of the collection filter body 54 from being stained, it is always visible to the user. Since it can be confirmed, it is easy to judge whether cleaning work is necessary.

  When the secondary filter body 60 is cleaned, the engagement gear 63b formed on the shaft body 63c rotates the transmission gear 62b of the dust removing body 62 by grasping and pulling up the handle 63. Thereby, the dust remover 62a of the dust remover 62 rotates while contacting the upstream side surface of the secondary filter 60b, and the dust collected by the secondary filter 60b is removed, and the opening 64a of the primary filter body 61 is removed. Further, the dust is stored in the dust accumulation portion 64e. At this time, after at least the dust remover 62a is rotated one or more times, the stopper 63d comes into contact with the upper end of the slit 64g of the bearing 64d, and when the handle 63 is pulled up, the entire primary frame 64 is taken out from the main body 40. I can do it.

  At this time, if the handle 63 is moved up and down to such an extent that the stopper 63d does not contact the upper end of the slit 64g, the secondary filter 60b can be removed without removing the primary filter body 61. If the primary filter body 61 is removed from the main body 40 by holding the handle 63, the dust of the primary filter 65 is treated, and the dust accumulated in the dust accumulation portion 64e is thrown away from the opening 64a. I can finish it.

  Thereafter, when the guide ribs 64c formed on both sides of the primary frame body 64 are aligned with the guide grooves 53a and pushed in, the engaging gear 63b formed on the shaft body 63c is again engaged with the transmission gear 62b of the dust removing body 62. In addition, the transmission gear 62b is rotated, and the dust remover 62 removes dust left in the secondary filter 60b and securely stores the dust in the dust accumulation portion 64e.

  As described above, according to the present embodiment, the dust removing body 62 can be obtained via the transmission gear 62b engaged with the engagement gear 63b of the shaft body 63c only by grasping the handle 63 and taking it out of the primary frame 64. Can be driven to easily remove the dust from the secondary filter body 60.

  Furthermore, after the handle 63 is pulled out and then lifted, the secondary filter body 60 is cleaned, and then the primary filter body 61 is detached from the main body 40, and the primary filter body 61 can be easily cleaned. Also, when the primary filter body 61 is mounted on the main body 40, the secondary filter body 60 is cleaned, so that the secondary filter body 60 can be more reliably cleaned.

  Further, when the handle 63 is pulled out by a predetermined distance and then lifted, the stopper 63d is in contact with the upper end of the slit 64g of the bearing 64d, so that the primary frame body 64 can be easily taken out from the main body 40. At this time, since the predetermined distance is formed so that the dust removing body 62 rotates at least once or more, the dust removal of the secondary filter body 60 is reliably performed.

  Further, since the elastic body 66 that urges the handle 63 downward is provided, when the handle 63 is lifted and then released, the handle is lowered by the urging force of the elastic body 66. The operation of pulling down is unnecessary and convenient.

  Further, the portion provided with the slit 64g of the bearing 64d of the primary filter body 61, that is, the vicinity of the transmission gear 62b is used as the shaft body regulating portion 64h that prevents the engagement gear 63b from being detached from the transmission gear 62b. The engagement gear 63b and the transmission gear 62b are not disengaged when the handle 63 is operated, and the dust removal of the secondary filter body 60 can be performed reliably.
