Description

  The present invention relates to a washing machine, and more particularly to a washing machine having a drying function.

  In a washing machine having a drying function, lint accumulated on a filter during a drying operation leads to a decrease in drying performance, and therefore the user needs to care for each time after the operation is completed. Since this imposes a burden on the user, it has been considered to have a function of automatically cleaning the filter.

  As a conventional first washing machine having such an automatic filter cleaning function, a filter is disposed in a circulation path portion that flows from the bottom to the top, water is poured from above into a shower, and is deposited and deposited on the lower surface of the filter. There are some which wash away yarn waste (for example, refer to JP 2009-142351 A).

  In addition, as a conventional second washing machine having an automatic filter cleaning function, a filter is disposed at the outlet on the water tank side of the path through which the circulating air exits the water tank and enters the drying unit, and the drum centrifugal force during the drying operation Is set so that the dustproof body arranged behind the drum moves on the filter, so that the yarn waste is always removed during the drying operation to prevent a decrease in drying efficiency (for example, JP 2008-272222 A). No. Publication (Patent Document 2)).

  In addition, as a conventional third washing machine equipped with a filter automatic cleaning function, there is a thing that provides a bypass as a lint collection path in the circulation path and collects lint accumulated on the filter in a predetermined collection box (for example, JP, 2004-154321, A (patent documents 3) reference).

JP 2009-142351 A JP 2008-272222 A JP 2004-154321 A

  In the first conventional washing machine, there is a problem in that the filter mounting direction is restricted to the horizontal direction in order to sprinkle the filter part from the top to the bottom to wash away lint, so that the structure cannot be easily removed.

  In the second conventional washing machine, a filter is disposed behind the water tank, and a dustproof body having a spring that moves up and down by centrifugal force is attached to the rear of the drum. Therefore, there is a problem that the structure becomes complicated because it moves to the position of the filter and scrapes off the lint.

  Further, in the third washing machine of the prior art, a bypass that is different from the original circulation path is provided, and the yarn waste accumulated on the filter in the circulation path is automatically collected. There is a problem that it becomes complicated.

  Therefore, an object of the present invention is to provide a washing machine that can easily remove filter lint and the like with a simple configuration without complicating the mounting direction of the filter, the cleaning structure, and the air path.

In order to solve the above problems, the washing machine of the present invention is:

Thereby, when the door 7 is closed, the door 7 is brought into close contact with the packing 18 to prevent the liquid in the water tank 2 from leaking out of the water tank 2. Further, when the drain motor 23 opens the drain valve 22, the liquid in the water tank 2 sequentially flows through the drain duct 19, the connection case 20, and the drain hose 21 to the outside of the outer box 1. Further, when the circulation pump 24 is driven with the drain valve 22 closed, the liquid in the water tank 2 can be taken out of the water tank 2 and returned to the water tank 2 through the drain duct 19 and the circulation duct 25. . Further, the connection case 20 accommodates the lint filter 70.

  The drum 3 is disposed so that the rear side is lowered with respect to the front side and is inclined with respect to the horizontal direction. Further, a drum opening 26 facing the outer box opening 6 and the water tank opening 16 is provided on the front surface of the drum 3. Further, a plurality of small holes 27 (only six are shown in FIG. 2) are provided in the peripheral wall of the drum 3 over the entire circumference. A plurality of baffles 28 (only one is shown in FIG. 2) are provided on the inner surface of the peripheral wall of the drum 3 so as to protrude radially inward.

  FIG. 3 is a schematic cross-sectional view for explaining the drying unit 100 of the drum type washing and drying machine. In FIG. 3, the same components as those shown in FIG. In FIG. 3, reference numeral 200 denotes a drying filter attached to the drying unit 100.

  As shown in FIG. 3, in this drum type washing and drying machine, a drying unit 100 for drying laundry is disposed above the water tank 2 and on the back side.

  In the drying operation, in the drying operation, the air containing the moisture of the laundry is introduced from the rotating drum 3 through the outlet 66 and the outlet duct 62, and heated hot air is introduced into the drum 3 through the inlet duct 61, Supply via the inlet 64.

  The warm air introduced into the drum 3 hits the laundry in the drum 3, deprives the laundry of moisture and becomes moist air, and enters the drum opening 26 of the drum 3 and the small holes 27 formed in the peripheral wall of the drum 3. It flows out into the water tank 2, and is led out into the lead-out duct 62 through a lead-out port 66 that opens at the bottom bottom of the water tank 2.

  A cooling plate 50 is disposed below the water tank 2 and between the inner peripheral surface of the water tank 2 and the outer peripheral surface of the drum 3. The cooling plate 50 has a rear side inclined downward, and the water supply from the cooling water duct 14 flows from the front to the rear along the upper surface of the cooling plate 50. A plurality of water reservoirs 50a are formed in the cooling plate 50 at predetermined intervals in the front-rear direction.

  To such a cooling plate 50, tap water flowing through the cooling water duct 14 is supplied during the drying operation. Specifically, the tap water that has flowed through the cooling water duct 14 is discharged onto the upper surface of the cooling plate 50 and flows backward while staying in the water reservoir 50a.

  During the drying operation, the air heated by the drying unit 100 blows out from the inlet 64 into the drum 3. Thereby, the air hits the laundry in the drum 3, and the moisture of the laundry evaporates. The moisture-containing air flows out of the drum 3 through the small holes 27 and flows along the cooling plate 50. At this time, tap water is supplied to the cooling plate 50 through the cooling water duct 14. Then, the air containing moisture is cooled by the tap water flowing on the cooling plate 50 and is cooled by the cooling plate 50 cooled by the tap water. Thereby, the water | moisture content of the air which flows along the said cooling plate 50 condenses effectively. That is, the air is sufficiently dehumidified to become low humidity. The low-humidity air is sucked into the drying unit 100 through the outlet 66 and the outlet duct 62, and then heated to return into the drum 3 again.

  FIG. 4 shows forms of the introduction duct 61 and the outlet duct 62. 4, the same reference numerals are assigned to the same components shown in FIGS.

Further, as a part of the lead-out duct 62 (shown in FIG. 3), a concave groove 62a extending upward from the lead-out port 66 is provided. Covers 51 and 52 are attached to the bottom of the water tank 2 so as to cover the concave grooves 61a and 62a. A cooling plate 50 is disposed in the lower part of the water tank 2 and in the vicinity of the outlet 66.

  The air passage P (shown in FIG. 5), the inlet duct 61, the inlet 64, the drum 3 (shown in FIG. 3), the outlet 66 and the outlet duct 62 of the drying unit 100 constitute a circulation drying passage.

  FIG. 5 is a schematic diagram of a longitudinal section of the drying unit 100, and FIG. 6 is a schematic diagram of the top surface of the drying unit 100. 5 and 6, the left side is the front of the drum type washing and drying machine, and the right side is the rear side of the drum type washing and drying machine.

  As shown in FIGS. 5 and 6, the drying unit 100 includes a casing 101, a blower fan 102 disposed on the upper portion of the casing 101, a motor 103 that rotationally drives the blower fan 102, a heater 104, and an upper portion of the casing 101.

  A suction port 101 a that opens toward the side is provided on the rear side of the casing 101. A lead-out duct 62 is connected to the suction port 101a. In addition, an outside air inlet 101 b communicating with the outside is provided on the lower side of the casing 101. In the wind passage P of the casing 101, an intake flap 110 that opens and closes the outside air intake port 101b is rotatably arranged. The shaft 110a of the intake flap 110 is driven by a motor (not shown).

  Further, an exhaust flap 120 is rotatably disposed in an opening 106 a of an exhaust duct 106 that communicates with the wind passage P in the casing 101.

  The air in the water tank 2 (shown in FIGS. 2 and 3) is driven by rotating the blower fan 102 by the motor 103 while the intake flap 110 closes the outside air inlet 101b (first flap position). 3 is drawn into the blower fan 102 through the air passage P in the casing 101 through the outlet port 66, the outlet duct 62, and the inlet port 101a shown in FIG. 3, heated by the heater 104, and blown out from the outlet 105. 3 is supplied into the drum 3 through the introduction duct 61 and the introduction port 64 shown in FIG.

  FIG. 7 shows a schematic diagram of a longitudinal section of the drying unit 100 during the exhaust drying operation. The same components as those in FIG. 5 are denoted by the same reference numerals. In FIG. 7, the air passage P in the casing 101 shown in FIG. 5 is separated into the air passages P 1 and P 2 by the intake flap 110.

  As shown in FIG. 7, during the exhaust drying operation, the intake flap 110 is in a state where the outside air intake port 101b is opened (second flap position), and the exhaust flap 120 is where the opening 106a of the exhaust duct 106 is opened. Then, by rotating and driving the blower fan 102 by the motor 103, the outside air sucked into the blower fan 102 through the outside air suction port 101b and the air passage P1 is heated by the heater 104 (shown in FIG. 6). It blows out from the blower outlet 105 and is supplied into the drum 3 through the inlet duct 61 and the inlet 64. The air in the water tank 2 passes through the air passage P2 in the casing 101 through the outlet port 66, the outlet duct 62, and the suction port 101a, and is discharged to the outside through the exhaust duct 106.

  The air passage P, the introduction duct 61, the introduction port 64, the drum 3 (shown in FIG. 3), the outlet port 66, the outlet duct 62, and the exhaust duct 106 of the drying unit 100 constitute an exhaust drying passage.

  Next, the automatic cleaning of the drying unit 100 will be described below with reference to FIG. FIG. 8 shows a schematic diagram of a longitudinal section of the drying unit 100 during automatic cleaning.

  As shown in FIG. 8, the intake flap 110 is rotated to the third flap position facing the filter surface of the dry filter 200. Here, the intake flap 110 is provided with a plurality of nozzles 300 connected to a water supply pipe (not shown). Then, by blowing water from the nozzle 300 toward the filter surface of the dry filter 200 in a shower shape, the yarn waste 250 accumulated on the filter surface of the dry filter 200 is removed. At this time, the removed yarn waste 250 flows down together with water into the lower part of the water tank 2 through the suction port 101a and the lead-out duct 62, and is discharged to the outside through the drainage duct 19.

  By performing this automatic cleaning function at the end of drying or during the washing operation, it is possible to prevent the drying performance from being deteriorated due to filter clogging during the next drying operation, and the filter is always dried while maintaining a clean condition. You can drive.

  FIG. 9 shows a perspective view of the drying filter 200 attached to the drying unit 100. As shown in FIG. 9, the dry filter 200 includes a handle portion 201 having a handle 201 a on the upper side, a box portion 202 that extends downward from the lower side of the handle portion 201 and that opens on one side surface, and a box portion 202. And a lid 203 covering the opening 202a. The lid 203 is provided with a substantially circular opening 203a facing the suction port 101a of the drying unit 100 shown in FIG. Moreover, the cover part 203 is attached to the box part 202 so that rotation is possible centering on a lower end.

  By removing the drying filter 200 from the drying unit 100 and opening the lid portion 203, yarn waste can be easily removed from the box portion 202.

  FIG. 10 is a horizontal sectional view of the drying filter 200 as viewed from the line XX shown in FIG. FIG. 10 shows a state where the lid 203 is closed.

  As shown in FIG. 10, the box portion 202 of the dry filter 200 includes a first vertical frame portion 210 as an example of a vertical frame portion extending in the vertical direction, and an upstream side and a horizontal side from the lower end of the first vertical frame portion 210. A bottom surface portion 220 as an example of a bent portion that is bent and extended in the direction, and second and third vertical frame portions 230 and 240 that are bent and extended in the upstream and lateral directions from both ends of the first vertical frame portion 210. Including. Moreover, the net | network part 211,231,241 is provided in the 1st vertical frame part 210 and the 2nd, 3rd vertical frame part 230,240, respectively. The surfaces of the mesh portions 211, 231, and 241 are substantially vertical filter surfaces of the dry filter 200.

  In the drying filter 200, the yarn waste 250 contained in the air sucked through the substantially circular opening 203a of the lid portion 203 stays mainly in the mesh portion 211 of the first vertical frame portion 210. Then, the air from which the yarn waste 250 has been removed is sucked into the blower fan 102 (shown in FIG. 5) on the downstream side of the drying filter 200.

  The net portions 231 and 241 of the second and third vertical frame portions 230 and 240 may not be provided. However, the net portions 211 of the first vertical frame portion 210 are clogged due to the presence of the net portions 231 and 241. However, the loss of the air passage P is small and the air blowing performance can be prevented from deteriorating.

  FIG. 11 is a schematic diagram of a longitudinal section of the drying unit 100 showing a state in which the drying filter 200 is removed. As shown in FIG. 11, the drying filter 200 is detachably attached in the vertical direction from the drying unit 100 at the top of the main body, so that the drying filter 200 can be easily attached and detached using the space above the main body. On the other hand, when the drum-type washing / drying machine is installed in a narrow place (for example, a washroom), it is structurally difficult to take out the drying filter from the side of the main body.

  According to the drum type washing / drying machine having the above-described configuration, when the drying unit 100 sucks air from the water tank 2 through the air passage P, the lint and the like are removed by the drying filter 200 whose filter surface is substantially vertical. Then, the lint and the like accumulated on the filter surface of the dry filter 200 is blown out in a shower shape from the nozzle 300 disposed on the downstream side of the dry filter 200 in the air passage P toward the dry filter 200. By doing so, the lint etc. accumulated on the filter surface opposite to the nozzle 300 are blown away to the upstream side and removed. At this time, since the filter surface of the dry filter 200 is substantially vertical, it is possible to employ a structure in which the dry filter 200 is taken out in a vertical direction in a narrow space above the main body. Further, the blown-off lint and the like flow down together with water into the outlet duct 62 and the like upstream of the suction port 101a of the air passage P of the drying unit 100, and after washing the outlet duct 62 and the like, the drainage duct 19 is passed through. Can be discharged to the outside. In this way, it is possible to easily remove the yarn waste and the like of the drying filter 200 with a simple configuration without complicating the mounting direction of the drying filter 200, the cleaning structure, and the air path.

  The dry filter 200 includes a first vertical frame portion 210 extending in the vertical direction, and a bottom surface portion 220 that is a bent portion extending from the lower end of the first vertical frame portion 210 upstream and in the horizontal direction. By using the dry filter 200 having at least the net part 211 provided in the first vertical frame part 210, even if lint or the like accumulated on the net part 211 falls, it can be received by the bottom part 220, It is possible to prevent the dry filter 200 from falling into the main body when taken out.

  Further, the air flow in the air passage P can be controlled with a simple configuration by the intake flap 110 disposed in the air passage P of the drying unit 100 and on the downstream side of the drying filter 200. For example, the air intake passage 110 switches the air passage P that discharges the air in the water tank 2 to the outside through the drying unit 100 or circulates the air in the water tank 2 through the drying unit 100. By providing the nozzle 300 in such an intake flap 110, the nozzle 300 can be disposed on the downstream side of the drying filter 200 without disturbing the airflow in the air passage P.

  Further, by setting the intake flap 110 to the first flap position, the circulation drying passage (P, 61, 64, 3, 66, 62) is closed and the exhaust drying passage (P1, P2, 61, 64, 3, 66). , 62, 106) is opened, and the air in the water tank 2 is discharged to the outside through the drying unit 100 and the exhaust drying passage. Further, by setting the intake flap 110 to the second flap position, the exhaust drying passage is closed and the circulation drying passage is opened, and the air in the water tank 2 is circulated through the drying unit 100. Further, by setting the intake flap 110 to the third flap position, the intake flap 110 faces the filter surface of the dry filter 200 and blows fluid (water in this embodiment) from the nozzle 300 toward the dry filter 200. Thus, the filter surface can be cleaned.

  Further, in a drum-type washing / drying machine in which it is difficult to take out the drying filter 200 from the side of the main body because it is installed in a narrow place (washroom), the drying filter 200 is detachably attached from the upper part of the main body. Thus, the drying filter 200 can be easily attached and detached using the space above the main body. Further, since the filter surface is substantially vertical, even if the filter has a large filter area, the filter 200 is taken out in the upper part of the main body by taking out the dry filter 200 along the direction parallel to the filter surface, that is, the vertical direction. There is no need to provide an opening.

  In the above embodiment, the drum type washing and drying machine has been described as the washing machine. However, the present invention may be applied to washing machines having other configurations.

Then, the lint and the like accumulated on the filter surface of the filter 200 is blown out from the nozzle 300 disposed on the downstream side of the filter 200 in the air passage P toward the filter 200 (for example, water). By doing so, the lint etc. accumulated on the filter surface opposite to the nozzle 300 are blown away to the upstream side and removed. At this time, since the filter surface of the filter 200 is substantially vertical, it is possible to adopt a structure in which the filter 200 is taken out in the vertical direction in a narrow space in the upper part of the main body. Further, the blown off lint and the like flow down together with the fluid (for example, water) into the suction path 62 on the upstream side of the suction port of the wind path P of the drying unit 100, and after washing the wind path, for example, the drainage path 19 It becomes possible to discharge to the outside.

  According to the embodiment, the airflow in the wind passage can be controlled with a simple configuration by the flap 110 disposed in the wind passage P of the drying unit 100 and on the downstream side of the filter 200. For example, the air passage in the water tank is exhausted to the outside through the drying unit 100 or the air passage for circulating the air in the water tank through the drying unit 100 is switched by the flap 110. By providing the nozzle 300 in such a flap 110, the nozzle 300 can be disposed on the downstream side of the filter 200 without disturbing the airflow in the air passage.

The position can be switched between a flap position, a second flap position where the exhaust drying passage is closed and the circulation drying passage is opened, and a third flap position facing the filter surface of the filter 200.

  According to the above embodiment, by setting the flap 110 to the first flap position, the circulation drying passage is closed and the exhaust drying passage is opened, and the air in the water tank is discharged to the outside through the drying unit 100 and the exhaust drying passage. . Further, by setting the flap 110 to the second flap position, the exhaust drying passage is closed and the circulation drying passage is opened, and the air in the water tank 2 is circulated through the drying unit 100. Furthermore, by setting the flap 110 to the third flap position, the flap 110 faces the filter surface of the filter 200, and the filter surface can be cleaned by blowing fluid from the nozzle 300 toward the filter 200.

In the washing machine of one embodiment,
The filter 200 is detachably attached in the vertical direction from the upper part of the main body.

  According to the above embodiment, in a washing machine in which it is difficult to take out the filter 200 from the side of the main body because it is installed in a narrow place (washroom), the filter 200 is detachably attached from the top of the main body in the vertical direction. Thus, the filter 200 can be easily attached and detached using the space above the main body. In addition, since the filter surface is substantially vertical, it is necessary to provide a large extraction opening at the top of the main body by removing the filter 200 along the direction parallel to the filter surface even if the filter has a large filter area. There is no.
