<Structure of detergent injection device>
FIG. 3 shows a perspective view of the detergent charging device 100 of the vertical washing machine, FIG. 4 shows a top view of the detergent charging device 100, and FIG. 5 shows an exploded perspective view of the detergent charging device 100.

  As shown in FIGS. 3 to 5, the detergent feeding device 100 includes a water supply unit 1, a detergent case 2 detachably housed in the water supply unit 1, and a flexible housing detachably housed in the water supply unit 1. It is composed of a finishing agent charging section 3.

  The detergent case 2 has a vessel-shaped stirring section 21 in which the detergent is stored. An annular flow path is formed by the outer wall 26, the bottom 27, and the inner wall 28 of the stirring section 21. The water flow swirls through this annular flow path. By providing a truncated cone-shaped convex portion 20 protruding upward on the bottom of the stirring portion 21, the outer peripheral side of the convex portion 20 serves as an inner wall 28.

  Further, the outer wall 26 of the stirring section 21 is provided with an inflow port 22 through which tap water flows into the stirring section 21. Further, the outlet 23 is provided in the center of the stirring section 21 and further inside the inner wall 28. The outflow port 23 is provided in the shape of a mortar above the convex portion 20, and has a through hole 23 a at the center of the bottom of the outflow port 23.

  Further, the water supply unit 1 is provided with a box body 1a having an open upper portion, an inflow path 11 provided on one side surface of the box body 1a and connected to a downstream end of a water supply pipe 170, and the other side surface of the box body 1a. An inlet 13 is provided on the lower side of the washing machine for supplying a mixed liquid of water and detergent into the washing tub 103 (shown in FIG. 2). Further, the inflow path 11 is configured to communicate with the inflow port 22 of the stirring section 21.

  A branch path 24 is provided on the outer wall 26 of the stirring section 21, and a drain pipe 30 (shown in FIGS. 10 and 11) is provided at the tip of the branch path 24. A siphon structure is provided by covering the drain cylinder 30 with the cap component 4. The bottom of the branch path 24 is inclined so as to gradually lower from the annular flow path of the stirring section 21 toward the tip side drain pipe 30.

  In the water supply unit 1, a box-shaped softening agent feeding section 3 is mounted. The softening agent input part 3 is provided with a second inflow port 31 on the side surface, which communicates with the second inflow path 12 connected to the water supply valve 180 (shown in FIG. 2).

  A second drain (not shown) is provided at the bottom of the softening agent charging section 3, and a cap component 5 is put on the second drain to provide a siphon structure. The bottom surface of the softening agent input portion 3 is inclined so as to gradually decrease toward the second drain.

<Main flow of water in stirring section>
FIG. 6 is a diagram for schematically explaining the water flow in the stirring section 21, the upper stage of FIG. 6 is a top view, and the lower stage is a drawing in which a transverse sectional view is schematically written.

  The water that has flowed in from the inflow port 22 swirls along the outer wall 26 of the stirring section 21, and the water level gradually rises. From the central outflow port 23 where the water level exceeds the height of the inner wall 28. It will be leaked. The inflowing water is not immediately discharged until the water level reaches the height of the inner wall 28, and swirls in the stirring unit 21 to obtain a stirring force.

<Secondary flow of water in stirring section>
FIG. 7 is a sectional view schematically explaining the water flow in the stirring section 21. Since the viscous action is weak near the water surface, the water flow is fast and the centrifugal force (arrow R1) becomes large, and near the bottom surface, the water flow is slow and the centrifugal force (arrow R2) becomes small due to the effect of the viscosity, and the centrifugal force circulates vertically. Secondary flow occurs. Specifically, the centrifugal force is small at the bottom of the stirring section 21, an inward flow is possible, the inner wall 28 rises, the water surface makes an outward flow, and the inner wall 28 circulates downward along the outer wall 26. This secondary flow promotes further stirring.

<Detergent injection>
The stirring section 21 also serves as a detergent charging section, and the volume of the stirring section 21 is selected according to the required detergent amount. FIG. 8 and FIG. 9 show examples of powder detergent injection.

  As shown in FIG. 8, in the example in which the water flow swirls into the donut shape, the water flowing from the inflow port 22 stirs while breaking down the powder from the bottom surface. By the action of the secondary flow, the vertical circulation flow increases the stirring force, and the powder detergent rides on the secondary flow and flows to the outlet 23 without remaining in the stirring section 21.

  Further, as shown in FIG. 9, in the example in which the agitating portion 21 is put in the vicinity from the center to the near side, the powder detergent comes around the portion where the water flow swirls and the outlet 23, and part of the detergent 22 enters the inlet 22. Although it will be spilled, the water flow from the outlet 23 flows into the water supply unit 1 without any problem.

<Dama of powder detergent>
A powder detergent can be crap when dissolved in water. Since the lump-shaped powdered detergent has a large size, centrifugal force acts and it floats on water, so that it does not immediately flow to the outlet 23. The lumps are gradually released by the stirring force of the water flow, and the melted substances flow out in order. Here, the lump is a lump of the powder detergent in which only the surface is dissolved in water and water hardly penetrates into the inside and is hardly dissolved.

<Branch route>
FIG. 10 is a diagram illustrating a path branched from the stirring unit 21. It is a relatively narrow branch path 24 that branches from the stirring section 21, and water flows into the branch path 24 when water flows in.

  The branch path 24 is provided so as not to obstruct the mainstream of turning, and a siphon structure in which the cap part 4 is covered on the drain tube 30 is provided at the tip thereof. Further, by inclining the bottom surface of the branch path 24 so as to gradually lower toward the siphon structure, it is possible to drain all the water in the stirring unit 21 without reducing the stirring force of the stirring unit 21. .

  The siphon structure composed of the drain cylinder 30 and the cap component 4 is an example of a drainage auxiliary section.

  FIG. 11 is a top view of the detergent case 2, in which an outer wall 26 of the stirring section 21 is provided with a branch path 24. A drain pipe 30 for a siphon is connected to the end of the branch path 24, and the drain pipe 30 is covered with a cap component 4 to form a siphon structure.

  The branch path 24 branches right beside the inflow port 22 and is provided so as to branch in a direction opposite to the main flow of the swirling water flow in the stirring section 21. By using a path that branches in the opposite direction to the main flow of the swirling water flow in the stirring section 21, it is possible to prevent the undissolved powder detergent from flowing into the branch path 24.

<Inlet>
The amount of water flowing in is generally 0.5 to 1.5 liters per minute, and even at a low flow rate of 0.5 liters per minute, stirring is performed, and at a rate of 1.5 liters per minute from the stirring section 21. It is necessary to prevent problems such as overflow, the powder detergent not being stirred, and the powder detergent not flowing out. In the part where the mainstream's momentum is weakened, the pile of powder detergent may not be able to collapse and the powder detergent may stick to the bottom and side surfaces, especially when the amount of water flowing in is 0.5 liters per minute. Likely to happen.

  There is sufficient momentum in the water flow near the inflow port 22, but the force of the water flow gradually disappears as it swirls in the stirring section 21, and the flow velocity becomes the slowest in front of the inflow port 22 (upstream side of the swirling water flow). The flow becomes such that the flow velocity is recovered near the inflow port 22. In order to obtain the required flow rate, the diameter of the inlet 22 is appropriately selected according to the stirring action.

  FIG. 12 is a view for explaining the installation angle of the inflow port 22 of the detergent case 2 in the vertical direction, and is a cross-sectional view taken along the line XII-XII shown in FIG. 11. The discharge direction of water from the inflow port 22 is inclined downward with respect to the horizontal direction, and water is discharged from the inflow port 22 toward the bottom surface of the stirring unit 21.

  The discharge direction of the water at the inflow port 22 of the inflow path 11 is set to an angle at which it collides with the bottom surface of the stirring unit 21 at a position distant from the inflow port 22, and the fast water flow is sent to a place where the water flow weakens, and the powder detergent is used. Can be cut down. Further, the discharge direction of water at the inflow port 22 is set so that a swirling water flow is formed in the stirring section 21.

  13 is a view for explaining the installation of the inflow port 22, and is a cross-sectional view taken along the line XIII-XIII shown in FIG.

  In the first embodiment, the center line of the inflow path 11 is formed so as to be substantially in contact with the outer wall 26. Since the water from the inflow port 22 flows in so as to contact the circle of the outer wall 26, the decrease in the force of the water can be minimized.

<Outlet>
The outlet 23 is provided at a position higher than the inner wall 28. The water level in the stirring unit 21 rises while the water and the powdered detergent that have flowed in through the inflow port 22 are stirred, and flow out from the outflow port 23. The detergent water flowing out from the outlet 23 to the water supply unit 1 (shown in FIG. 3) is supplied to the washing tub 103 (shown in FIG. 2) from the input port 13 (shown in FIG. 3).

  Japanese Patent Laid-Open No. 11-319380 and Japanese Patent No. 3636107 disclose a washing machine in which a detergent is dissolved in water by using a stirring blade that agitates water and the detergent in a detergent input box. In such Japanese Patent Laid-Open No. 11-319380 and Japanese Patent No. 3636107, the stirring blade and the power for driving the stirring blade are required, and the accumulated detergent may cause rotation failure of the stirring blade. It requires periodical maintenance, which raises the problem of high component costs and increased power consumption.

  In addition, Japanese Patent Laid-Open No. 2017-312 discloses a washing machine in which detergent water is foamed when a water flow collides with a plurality of projection shapes provided in a water injection path. In JP-A-2017-312, there is a problem that the structure becomes complicated because it is necessary to provide a complicated path or to provide a plurality of pins and ribs in the path.

  On the other hand, according to the vertical washing machine of the first embodiment, in the stirring section 21 of the detergent feeding device 100, the vessel-shaped stirring section 21 is driven by the force of the water discharged from the inflow port 22 of the inflow path 11. A water flow swirling inside can be created, and the swirling water flow efficiently dissolves the detergent (mainly powdered detergent) put in the stirring section 21 by the stirring action. Thereby, with a simple configuration, the detergent can be dissolved in water by the swirling water flow in the stirring unit 21, and then the detergent can be put into the washing tub 103 through the outlet port 23. Therefore, it becomes possible to reduce the undissolved residue of the detergent and prevent the deterioration of the cleaning performance, and the cleaning performance can be improved without providing the time for dissolving the detergent in the washing process. Further, the detergent can be dissolved in water with a simple structure without using a stirring mechanism such as a stirring blade or a driving unit thereof.

  Further, since the inflow port 22 is formed in the outer wall 26 of the stirring unit 21 of the detergent feeding device 100, a water flow along the outer wall 26 can be created, and the powder detergent piled in the stirring unit 21 can be formed. The momentum of breaking down the powder detergent is obtained, and a high stirring force that promotes the dissolution of the powder detergent is obtained. In addition, by providing the outlet 23 at a position higher than the inlet 22, water is spread over the entire stirring unit 21 before the outflow starts from the outlet 23, and it is possible to stir all of the detergent put in the stirring unit 21. Become.

  Further, by providing the truncated cone-shaped convex portion 20 projecting upward at the bottom of the stirring portion 21 of the detergent feeding device 100, it is possible to easily form the annular flow path in which the water flow swirls.

  In addition, by forming an annular flow path in the stirring section 21 of the detergent feeding device 100, the flow path is narrowed, the momentum of the swirling water flow is increased, and the stirring force can be further increased. In addition, in the annular flow path in the stirring section 21, a viscous action of water causes a secondary flow due to a flow velocity difference between the water surface and the bottom surface, and the secondary flow circulating in the vertical direction further enhances the stirring force. It becomes possible.

  Further, by providing the outflow port 23 on the center side of the stirring unit 21 of the detergent feeding device 100, it is possible to cause only the detergent sufficiently dissolved in the stirring unit 21 to flow out from the outflow port 23. The powder detergent randomly charged is agitated by the swirling main flow and the secondary flow, but the detergent gradually gathers toward the center side by the secondary flow, and the outlet at the center side of the stirring unit 21. By being sent to 23, all the detergent can be poured into the washing tub 103 and the undissolved detergent is prevented. Further, the lump-shaped powdered detergent is swirled outside the flow path in the stirring section 21 due to the centrifugal force, and the lumps are dissolved by the stirring action to dissolve or become powder particles, and the outlet 23 Flow to.

  Instead of the outlet 23 provided on the center side of the stirring unit 21 of the detergent feeding device 100, an outlet may be provided on the side wall and the upper side of the stirring unit 21 (see the third embodiment).

  Further, the outlet may be provided on the center side of the stirring section 21 of the detergent feeding device 100, and the outlet may be provided on the upper side of the side wall of the stirring section 21. As a result, only the detergent sufficiently dissolved in the stirring section 21 is allowed to flow out from the central outlet, while it is allowed to flow out from the side wall and the upper outlet of the stirring section 21 when the amount of water flowing from the inlet 22 is large. Thus, it is possible to prevent overflow from the stirring section 21.

  In addition, by branching from the side wall of the stirring section 21 of the detergent feeding device 100 to form one branch path 24 connected to the drainage auxiliary section (4, 30), the side wall of the stirring section 21 is changed to the branch path 24. The siphon structure (4, 30) as an example of the flow-in / drainage assisting unit makes it possible to drain the residual water that has not been discharged from the outflow port 23 and to discharge all the water supplied to the stirring unit 21. .

  Further, since the siphon structure is not arranged in the region in which the water flow swirls in the stirring section 21, it is possible to deal with the liquid detergent without disturbing the main flow of the swirling water flow and without reducing the stirring force.

  14 to 16 are modified examples in which the installation position of the inflow port 22 is different. In FIG. 14, the center line of the inflow path 11 connected to the inflow port 22A is arranged outside the tangent line of the outer wall 26. Further, in FIG. 15, the center line of the inflow path 11 connected to the inflow port 22B is arranged inside the tangent line of the outer wall 26. Further, in FIG. 16, the center line of the inflow path 11 which is continuous with the inflow port 22C is arranged further inside the tangent line of the outer wall 26.

  As shown in FIGS. 14 and 15, the openings of the inflow ports 22A and 22B become wider as the center line of the inflow path 11 becomes outward, so that the diameter of the inflow port 22 is reduced as shown in FIG. By taking the value, the discharge direction is stable regardless of the amount of water. In the case of the stirring section 21 having an annular flow path, the inflow port 22 needs to be arranged so as not to collide with the inner wall 28.

  In the first embodiment, the stirring portion 21 having the side surface of the truncated cone as the outer wall 26 is provided, but the shape of the outer wall of the stirring portion is not limited to this, and for example, the side surface of a truncated pyramid or the side surface of a cylinder is the outside. The wall may be a stirring unit as long as it is a vessel-shaped stirring unit capable of forming a swirling water flow.

[Second Embodiment]
FIG. 17 is a schematic diagram illustrating a stirring unit of a detergent charging device of a vertical washing machine as an example of the washing machine according to the second embodiment of the present invention. The vertical washing machine of the second embodiment has the same configuration as the vertical washing machine of the first embodiment except for the outlet of the stirring section of the detergent throwing device, and FIGS. . In FIG. 17, 2011 is an inflow path, 2027 is a bottom inside the stirring unit 2021, and 2028 is an inner side wall of the stirring unit 2021.

  Like the stirring portion 21 shown in FIG. 7 of the first embodiment, the outlet 23 is provided at the center of the convex portion 20 provided on the bottom of the stirring portion 21, while the second embodiment is different. In the vertical washing machine of No. 2, as shown in FIG. 17, the low convex portion 2020 provided on the bottom of the stirring unit 2021 is lower than the inflow port 2022. Therefore, the outlet 2023 provided in the center of the low convex portion 2020 is located at a position lower than the inlet 2022.

  According to the vertical washing machine having the above-described structure, the stirring section 2021 can generate a water flow swirling in the vessel-shaped stirring section 2021 by the force of the water discharged from the inflow port 2022 of the inflow path 2011. Due to the water flow, the detergent (mainly powder detergent) put in the stirring unit 2021 is efficiently dissolved by the stirring action. Thus, with a simple configuration, the detergent can be dissolved in water by the swirling water flow in the stirring unit 2021 and poured into the washing tub 103 (shown in FIG. 2). Therefore, it becomes possible to reduce the undissolved residue of the detergent and prevent the deterioration of the cleaning performance, and the cleaning performance can be improved without providing the time for dissolving the detergent in the washing process.

  Further, since the inflow port 2022 is formed in the outer wall 2026 of the stirring unit 2021, it is possible to create a fast water flow along the outer wall 2026, and the force of breaking down the pile of the powdered detergent charged in the stirring unit 2021 can be obtained. In addition to being obtained, a high stirring force that promotes dissolution of the powder detergent is obtained.

  Further, by providing the outlet 2023 on the center side of the stirring unit 2021, it is possible to cause only the detergent sufficiently dissolved in the stirring unit 2021 to flow out from the outlet 2023. The randomly added powder detergent is agitated by the swirling water flow and gradually sent to the outlet 2023 in the center of the agitation unit 2021, so that all the detergent can be introduced into the washing tub 103. , Prevent undissolved detergent. Further, the lump-like powdered detergent is swirled outside the flow path in the stirring section 2021 due to the centrifugal force, and the lumps are dissolved by the stirring action to dissolve or become powder particles, and the outlet 20233 is discharged. Flow to.

[Third Embodiment]
FIG. 18 is a schematic diagram illustrating a stirring unit of a detergent charging device of a vertical washing machine as an example of the washing machine according to the third embodiment of the present invention.

It is in the vicinity of 6022 and shifted to the upstream side of the swirling water flow.

  As a result, the flow velocity can be increased by narrowing the flow passage cross-sectional area in the low speed region (near the inlet 6022 and upstream of the swirling water flow) where the flow velocity is weakened by the water flow swirling in the annular flow passage formed in the stirring section 6021. In addition, it is possible to suppress variations in the speed of the swirling water flow, prevent the powder detergent from staying in the low speed region of the swirling water flow, and reduce the stirring force, and perform stable stirring.

  The vertical washing machine of the sixth embodiment has the same effects as the vertical washing machine of the first embodiment.

[Seventh Embodiment]
22 is a perspective view of a detergent case 7002 of a detergent throwing device of a vertical washing machine as an example of the washing machine according to the seventh embodiment of the present invention, FIG. 23 is a top view of the detergent case 7002, and FIG. It is sectional drawing of the detergent case 7002 seen from the XXIV-XXIV line of FIG. The vertical washing machine according to the seventh embodiment has the same configuration as that of the vertical washing machine according to the first embodiment except for the convex portion of the stirring section of the detergent throwing device and the bypass path. Is used. 22 to 24, 7023 is an outflow port, 7023a is a through hole, and 7027 is a bottom inside the stirring unit 7021.

<Bypass route>
FIG. 29 is a diagram illustrating a bypass path 7025 that branches the water flow of the stirring unit 7021 and returns to the stirring unit 7021 again. The water flow branched from the main flow in the agitation unit 7021 by the bypass path 7025 can receive a momentum of the main flow to form a relatively fast branched water flow that detours via the bypass path 7025. When the water flowing from the inflow port 7022 is stirred with the detergent in the stirring section 21, a branched water flow is generated in the bypass path 7025, and even if the powder detergent before dissolution is mixed in the bypass path 7025, the water is flown to the stirring section 7021 again. By returning, it will be stirred again.

  When the first path 7025a of the bypass path 7025 is provided so as to be in the swirling direction of the water flow and in contact with the outer wall 7026, water easily flows in, and the third path 7025c returning to the stirring unit 21 again is also outside at the confluence with the main flow. It may be provided so as to be in contact with the wall 7026.

  Further, since a branched water flow that is sufficiently fast with respect to the speed of discharge from the siphon structure is generated, it is possible to prevent the undissolved powder detergent from entering the inside of the siphon structure and clogging the inside of the siphon structure. The siphon structure can be arranged on the second path 7025b in the middle of. Here, the siphon structure is composed of a drain pipe 7030 and a cap component (not shown) that covers the drain pipe 7030.

  Further, as shown in FIGS. 25 to 28, the first path 7025a of the bypass path 7025 is provided with an opening at the upstream end above the bottom 7027 in the stirring section 7021. Since the powdered detergent before dissolution sinks below the swirling water flow in the stirring unit 7021, it becomes difficult to mix into the branched water flow flowing into the bypass path 7025, and the powdered detergent is effectively retained in the bypass path 7025. Can be suppressed.

  On the other hand, the bottom of the third path 7025c of the bypass path 7025 is inclined so as to gradually decrease from the annular flow path of the stirring section 7021 toward the tip side drain pipe 7030. Therefore, it is possible to drain the water from the third route 7025c of the bypass route 7025 and discharge all the water supplied into the stirring unit 21.

  According to the vertical washing machine described above, the bypass passage 7025 that branches from the outer wall 7026 of the stirring unit 7021 and merges into the stirring unit 7021 again can create a branched flow having a relatively high flow velocity. Become. By providing the bypass path 7025 with a siphon structure as an example of the drainage auxiliary portion, it is possible to prevent the powder detergent from being deposited near the bypass path 7025 and the siphon structure.

  The vertical washing machine of the seventh embodiment has the same effects as the vertical washing machine of the first embodiment except for the effect of the configuration of the branch path 24 of the first embodiment.

  In the seventh embodiment, one bypass path 7025 that branches from the sidewall of the stirring unit 7021 and merges into the stirring unit 7021 again is formed, but branches from the sidewall of the stirring unit 7021 and merges into the stirring unit 7021 again. A plurality of bypass paths may be formed.
