Description

  The present invention relates to a washing / drying machine for drying clothes by supplying air for drying after washing clothes and the like, and more particularly, warmed air for drying clothes in a washing / dehydrating tank for washing, rinsing and dehydrating. And a washing / drying machine having an air passage for drying the clothes by circulating the air.

  Drying clothes using a washing and drying machine is a combination of waste heat generated from components such as an electric motor that rotates a washing and dewatering tank and an electric fan fan, and / or heat from a dedicated heat source such as a heater. Warm air is produced, and the warmed air is warmed by a blower fan and blown onto clothing in the rotating drum at a high speed so as to suppress the occurrence of “wrinkles” and perform drying.

  At this time, water vapor evaporated from the residual moisture of the clothing is generated by the warm air, and it is necessary to remove this water vapor.

  As a technique for this purpose, by flowing tap water through the air passage disposed between the outer tub and the back cover, the hot air containing water vapor is cooled by using low temperature tap water. A water-cooled dehumidification method has been proposed in which moisture is removed by condensation. Details of the washing / drying machine having such a configuration are described in Japanese Patent Application Laid-Open No. 2010-82346 (Patent Document 1).

JP 2010-82346 A

  The washing and drying machine described in Patent Document 1 blows warmed air through the air passage to the clothes that have been dehydrated in the washing and dewatering tub. An air circulation passage is formed.

  Since the washing and dewatering tub rotates while drying, the lint that peels off from the clothes as the drying progresses, the lint after washing that remains in the washing and dehydration tub, or dust, together with the circulating air, enters the ventilation passage. To move on. In particular, dust containing the yarn waste (hereinafter simply referred to as dust) is attached to a part of the air passage located in the outer tub and the back cover.

  For the purpose of dehumidifying the circulating air and washing away dust, a cooling nozzle that flows tap water for dehumidification is removed in this air passage, and dust attached to the wall of the air passage is removed separately from the cooling nozzle. There is a cleaning nozzle for running tap water.

  The cooling nozzle flows tap water in the downward direction of the washing / drying machine, and the cleaning nozzle flows tap water in the downward and lateral direction of the washing / drying machine. It was.

  However, the air passage has a passage configuration that passes between the outer tub and the back cover, passes through the space above the outer tub and below the upper surface cover, and reaches the washing and dewatering tub. Therefore, it was confirmed that a large amount of dust adheres to the wall surface of the bent portion of the air passage.

  The main reason for this is that the circulating air undergoes a large change of direction at the bent portion, and dust is separated from the air. Since dust and the like are still dry during the drying operation, dust easily adheres to the wall surface of the air passage when the air rides on the circulating air and collides with the air passage with speed. In particular, it was confirmed that a lot of dust adheres to the wall surface where the circulating air in the bent portion collides.

  However, the cooling nozzle is configured to flow tap water toward the lower side of the washing / drying machine, and the cleaning nozzle is configured to flow tap water toward the lower side and lateral direction of the washing / drying machine. Therefore, the dust adhering to the wall surface near the bent portion could not be washed away.

  For this reason, a bad odor is generated from the accumulated dust, which leads to an unpleasant environment for the user, which is not preferable. In addition, if dust accumulates over a long period of time, drying efficiency may decrease due to the phenomenon that the cross-sectional area of the air passage is reduced or, in extreme cases, the air passage is blocked. .

  An object of the present invention is to provide a washing / drying machine capable of cleaning dust accumulated in the air passage passage, and in particular, dust attached to the wall surface of the air passage above the cleaning nozzle can be washed. It is to provide a laundry dryer.

  A feature of the present invention is that it is connected to an air passage that constitutes a part of the air passage on the lower side of the upper surface cover that constitutes the housing, and is disposed between the outer tank and the back cover that constitutes the housing. The vertical air passage is formed by a vertical passage, an oblique passage formed following the longitudinal passage, and a lateral passage formed following the oblique passage. A washing / drying machine is provided with a washing nozzle disposed in the middle of the passage, and provided with a washing port for ejecting washing water in a lateral direction, a downward direction, and an upward direction with respect to the wall surface of the vertical passage.

  According to the present invention, cleaning water can be supplied from the cleaning nozzle in the upward, lateral, and downward directions, and dust accumulated in the air passage can be removed. In particular, it is possible to clean dust accumulated in an oblique passage above (downstream as viewed from the air flow) the cleaning nozzle.

  The above is the approximate configuration of the washing / drying machine, and the flow of the circulating air for drying is indicated by the flow line indicated by the thick arrow. However, the present invention relates to the air passage 29 through which the circulating air flows. Description of the operation of the machine is omitted.

  Next, the cleaning mechanism of the air passage 29 according to the present invention will be described with reference to the drawings. FIGS. 4 and 5 show a cross section of the longitudinal air passage 40 constituting a part of the air passage 29 provided with the cleaning mechanism. Yes.

  4 and 5 show a state in which the air passage switching valve switches the air passage. FIG. 4 shows that the air passage switching valve 43 blocks communication with the inside of the housing 1 and the air passage 29 circulates air. FIG. 5 shows a state where the air passage switching valve 43 blocks the air passage and sucks air inside the housing 1.

  4 and 5, reference numeral 40 is a cylindrical vertical air passage having a rectangular cross section installed in a space between the outer tub 2 and the back cover 1 d, and this is a back cover 1 d by a fixing screw boss 41. It is fixed to.

  The lower part of the vertical air passage 40 is connected to the lower inside of the outer tub 2 as described above, and the upper part of the vertical air passage 40 is a horizontal air passage (located in the space between the top cover 1e and the outer tub 2). (Not shown).

  The connecting portion 42 to the lateral air passage is composed of a lateral passage 42A and an oblique passage 42B, and the lateral passage 42A is connected to the lateral air passage. The oblique passage 42B is provided with an air passage switching valve 43, and is provided with a valve seat 44 formed inside the oblique passage 42B and an air intake 45 opened in a wall portion forming the oblique passage 42B.

  When the air passage switching valve 43 closes the air intake 45, the lateral passage 42A and the oblique passage 42B are connected, and when the air passage switching valve 43 opens the air intake 45 and closes the valve seat 44. The lateral passage 42A and the oblique passage 42B are blocked.

  The oblique passage 42B is formed continuously to the longitudinal passage 40A of the longitudinal blower passage 40, and the cleaning nozzle is located below (upstream as viewed from the air flow) the connection portion between the longitudinal passage 40A and the oblique passage 42B. 46 and a cooling nozzle 47 is fixed to the lower side.

  A meandering rib 48 is formed below the cooling nozzle 47 so that tap water supplied from the cooling nozzle 47 and the washing nozzle 46 meanders and flows to improve heat exchange efficiency with circulating air. I am doing so. These tap water for cleaning and cooling flows into the outer tub 2 after falling down the vertical passage 40A, and is then drained.

  Here, in the drawing, a cleaning nozzle 46 and a cooling nozzle 47 are arranged in a direction perpendicular to the paper surface. The cooling nozzle 47 flows tap water downward, and the cleaning nozzle 46 is downward and lateral. Tap water flows on both sides of the direction.

  Since the cleaning nozzle 46 is arranged close to one side of the vertical passage 40A, one surface does not contact one wall surface of the vertical passage 40A and faces the first predetermined distance, and the other surface. Is opposed to the other wall surface of the vertical passage 40A at a second predetermined distance longer than the first predetermined distance, and the tap water flows in the lateral direction. Similarly to the cooling nozzle 47, the cleaning nozzle 46 allows tap water to flow downward in the longitudinal passage 40A.

  Further, the cleaning nozzle 46 is configured to supply tap water toward the oblique passage 42B, and thereby is configured to wash dust adhering to the oblique passage 42B.

  The configuration of the cleaning nozzle 46 will be described in detail below. FIGS. 6 and 7 are a front view and an external perspective view of the cleaning nozzle 46 according to the present invention, and the cleaning nozzle 46 is connected to a water supply solenoid valve (not shown). The tap water supply part 49 and the L-shaped washing water supply part 50 intersecting with the tap water supply part 49 at a right angle are configured.

  The cleaning water supply unit 50 has a cleaning water passage (not shown) communicating with the tap water supply unit 49 inside, and the cleaning nozzle 46 has a plurality of lines arranged in a row communicating with the cleaning water passage. A lateral cleaning port 51, a plurality of downward cleaning ports 52 (not shown in FIGS. 6 and 7) arranged in a row, and a plurality of upward cleaning ports 53 also arranged in a row. It has.

  The direction of each of the cleaning ports 51 to 53 is determined in three directions. Since the horizontal cleaning port 51 has the above-described configuration, it is orthogonal to the wall surface of the vertical passage 40A. The cleaning water is supplied in the horizontal direction (the supply state is a state in which the water is ejected at a speed so as to collide with the wall surface of the vertical passage), and the lower cleaning port 52 is in the same supply state as the horizontal cleaning port 51 The cleaning water is supplied in a downward direction parallel to the wall surface of the passage 40A, and the upward cleaning port 53 is attached so as to clean dust attached to the oblique passage 42B in the same supply state as the lateral cleaning port 51. In this state, the cleaning water is supplied to the oblique passage 42B.

  The number and arrangement position of each cleaning port vary depending on the size of the air passage, and the optimum number and position are determined depending on the width of the air passage.

  8, 9, and 10 are cross-sectional views of portions of the cleaning nozzle 46 where the lateral cleaning port 51, the lower cleaning port 52, and the upper cleaning port 53 are provided, with respect to the cleaning water passage 54. The lateral cleaning port 51, the downward cleaning port 52, and the upward cleaning port 53 are communicated with each other.

  Here, the washing water passage 54 has a passage section that is long in the vertical direction, and the lateral washing port 51, the lower washing port 52, and the upper washing port 53 can communicate with each other.

  In FIG. 8, the horizontal cleaning port indicates one horizontal cleaning port 51 </ b> A of the two-way cleaning ports that are directed to the opposite wall surface to supply cleaning water to the opposite wall surface of the vertical passage 40 </ b> A as described above. ing. The lateral cleaning port 51A communicates with a lower portion of the cleaning water passage 54, which jets cleaning water toward the wall surface at the second predetermined distance as described above. The lateral cleaning port 51 is designed to eject a large amount so as to supply cleaning water to the wall surface at the second predetermined distance and two wall surfaces adjacent thereto.

  In FIG. 9, the upward cleaning port 53 is communicated with the uppermost portion of the cleaning water passage 54, which jets the cleaning water toward the oblique passage 42B as described above.

  Further, in FIG. 10, a lateral cleaning port 51B provided separately from the lateral cleaning port 51A shown in FIG. 8 is communicated with a lower portion of the cleaning water passage 54, which is the first predetermined as described above. The cleaning water is ejected toward the wall surface at a distance.

  Here, the diameter of the lateral cleaning port 51B is configured to be larger so that the amount of cleaning water supplied is smaller than that of the lateral cleaning port 51A. This is because the cooling nozzle 47 also flows tap water toward the wall surface having the first predetermined distance, so that much washing water is not required.

  In addition, a lower passage 52 communicates with the lowermost portion of the washing water passage 54, and this supplies tap water toward the wall surface having a first predetermined distance, and the supply amount thereof is also as described above. Further, since there is a part for the cooling nozzle 47, so much washing water is not required.

  Here, the supply amount of the cleaning water of the horizontal cleaning port 51, the downward cleaning port 52, and the upward cleaning port 53 of the cleaning nozzle 46 is as follows: the horizontal cleaning port 51> the downward cleaning port 52> the upward cleaning port. There are 53 relationships.

  This is because the lateral cleaning port 51 needs a lot of cleaning water because it needs to clean the three wall surfaces of the vertical passage 40A, and the downward cleaning port 52 has the cooling nozzle 47 and the vertical passage 40A. It is only necessary to supply the cleaning water to the remaining one wall surface, the upward cleaning port 53 may be substantially ejected to the hot air collision portion of the oblique passage 42B, and it is desired to increase the collision speed of the cleaning water. The above relationship was adopted. The relationship between the lower cleaning port 52 and the upper cleaning port 53 may be reversed from the relationship with the cooling nozzle 47.

  4 and 5, the cleaning nozzle 47 is attached to the wall surface on the back cover side in the vicinity of the connection portion between the vertical passage 40A and the oblique passage 42B, so the upward cleaning port 53 extends along the vertical passage 40A. If it is opened, cleaning water is supplied near the starting point of the oblique passage 42B, and there is a concern that a sufficient cleaning effect cannot be obtained.

  For this reason, the upward cleaning port 53 is oriented near the center of the oblique passage 42B at an angle so that cleaning water can be supplied toward the vicinity of the center of the oblique passage 42B. Preferably, the upward cleaning port 53 is directed to the wall surface of the oblique passage 42B in the vicinity where the center lines of the vertical passage 40A and the horizontal passage 42A intersect.

  Here, since the vertical air passage 40 has a rectangular cross section, the wall surface of the oblique passage 42Bno is also on a plane forming a rectangle, so that a plurality of washing water is supplied so as to hit this plane. In the case of a slit-shaped cleaning port, cleaning water having a shape along this is supplied.

  The shapes of the lateral cleaning port 51, the lower cleaning port 52, and the upper cleaning port 53 described above are circular so as to create a circular water flow. However, the present invention is not limited to this, and as described above, the slits are formed. It goes without saying that the shape may be a shape.

  In the circulation drying operation in which the air passage switching valve 43 blocks the air intake 45 and connects the lateral passage 42A and the oblique passage 42B, the washing water is directed upward from the upper washing port 53 of the washing nozzle 47. When the water is ejected, the washing water hitting the wall surface of the oblique passage 42B rebounds, and there is a possibility that splashes may fly to the drying filter ahead of the lateral passage 42A.

  Therefore, when the cleaning water is ejected from the upper cleaning port 53 of the cleaning nozzle 47, the air passage switching valve 43 closes the valve seat 44 of the oblique passage 42B and blocks the connection between the lateral passage 42A and the oblique passage 42B. In order to prevent the spray from splashing up to the drying filter.

  Here, the washing water blocked by the air passage switching valve 43 hangs down from the air passage switching valve 43 and is located along the wall surface of the vertical passage 40A (located on the outer tub 2 side) together with the washing water ejected from the lateral washing chestnut 51. To the wall).

  Note that the cooling nozzle 47 and the cleaning nozzle 46 are provided separately, but in some cases, the cooling nozzle 47 can also be used as the cooling nozzle 47.

  In this case, the supply amount of the cleaning water supplied from the lower cleaning port 52 and the horizontal cleaning port 51B may be designed so as to obtain a supply amount that can cover the cooling nozzle 47.

  Further, even when a care tool is used, it has been impossible to clean until the air path switching valve 43 is exceeded, whereas in the present embodiment, the vicinity of the air path switching valve 43 is cleaned. Since the nozzle 47 can be used for cleaning, a higher-grade washing / drying machine can be provided.

  As described above, in the present invention, it is possible to provide a washing / drying machine capable of cleaning dust accumulated in the air passage passage, and in particular, dust attached to the wall surface of the air passage above the cleaning nozzle. A washing / drying machine that can be washed can be provided.
