Description

Washing machine

Technical Field

The present invention relates to a washing machine having an automatic supply mechanism for automatically supplying a liquid detergent, a liquid softener, or other washing liquid.

Background

For example, patent document 1 describes a washing machine capable of automatically feeding a liquid detergent into a washing and dehydrating tub.

The washing machine of patent document 1 includes a detergent box provided in a housing and containing a liquid detergent. The detergent box closes the inside by closing a replenishment port for replenishing liquid detergent by a detergent box cover, and has an air flow inlet and a liquid discharge port. The air inlet is connected to an air pump. When the air pump works, the air pressure in the sealed detergent box rises, and the liquid detergent in the detergent box is pushed out from the liquid outlet and is put into the washing and dehydrating barrel.

In the above-described washing machine, when the liquid detergent remaining in the liquid discharge port is solidified into a gel form with age, and the solidified liquid detergent gradually accumulates, the liquid discharge port may be clogged. In this case, the liquid detergent may not be appropriately supplied.

Therefore, it is necessary to remove the solidified liquid detergent from the liquid discharge port, but the detergent box is disposed inside the housing, i.e., inside the washing machine. Therefore, it is difficult for a user to clean the liquid discharge port from the outside to remove the solidified liquid detergent.

Disclosure of Invention

Problems to be solved by the invention

The present invention has been made in view of the above problems, and an object of the present invention is to provide a washing machine capable of easily removing a washing liquid agent solidified at an outlet port portion of a casing (tank) from the outside.

Means for solving the problems

The washing machine of the main scheme of the invention comprises: a box body; a washing tub disposed in the cabinet to wash laundry; and an automatic feeding mechanism for automatically feeding the liquid agent for washing into the washing tub. Wherein, the automatic input mechanism includes: a box body configured in the box body and used for storing the liquid; an outlet portion provided in the cartridge and having a flow path through which the liquid discharged from the cartridge flows; and an anti-clogging member that is inserted into the case from the outside of the case in an accessible manner, in which a tip end portion of the anti-clogging member enters the flow path in an inserted state, and the liquid agent solidified in the flow path is captured by the tip end portion of the anti-clogging member.

According to the above configuration, the detergent for washing solidified in the flow path is caught by the distal end portion of the clogging member due to adhesion or the like at the time of solidification. When the clogging member is taken out from the case body to the outside, the tip end portion thereof is taken out to the outside together with the solidified liquid. This allows the solidified liquid agent to be removed from the flow path. Then, the solidified liquid detergent is removed from the top end portion of the clogging member by washing the top end portion.

Thus, according to the above configuration, when the solidified liquid agent accumulates in the flow path of the discharge port, the solidified liquid agent can be easily removed from the outside of the washing machine, and the discharge port can be easily prevented from being clogged.

In the washing machine according to the present aspect, the automatic supply mechanism may further include a supply port provided in the casing and through which the liquid agent is supplied. In this case, the clogging preventing member includes: a filter unit detachably attached to the inlet port and capturing foreign matter entering the case from the inlet port; and an anti-clogging portion including the tip portion and integrated with the filter portion.

According to the structure, foreign matters can be prevented from entering the box body from the feeding opening. Further, the filter portion is attached to the inlet, and the tip of the anti-clogging portion can be disposed in the flow path of the discharge port portion. Further, the inlet for introducing the liquid agent can be used as an insertion opening into which the blocking prevention member is inserted into the case.

In the washing machine of the scheme, the following structure can be adopted: the discharge port is provided at the bottom of the case, is formed to extend downward from the bottom and bend laterally, and has a vertical first flow path and a lateral second flow path included in the flow paths. In this case, the distal end portion enters the first flow path from above, and a receiving portion that covers a lower end surface of the first flow path from above is provided at a distal end of the distal end portion.

According to the above configuration, the liquid agent solidified in the first flow path can be received from below by the receiving portion, and when the distal end portion of the plug member is lifted upward in the first flow path, the solidified liquid agent is less likely to fall from the distal end portion. Therefore, the solidified liquid agent is easily recovered through the clogging preventing member.

Effects of the invention

According to the present invention, it is possible to provide a washing machine capable of easily removing a washing liquid agent solidified at an outlet port portion of a cartridge from the outside.

The effects and significance of the present invention will become more apparent from the description of the embodiments shown below.

Detailed Description

Hereinafter, an embodiment of a washing machine according to the present invention will be described with reference to the drawings.

Fig. 1 is a side sectional view of a fully automatic washing machine 1.

The full automatic washing machine 1 includes a casing 10 constituting an outer contour. The case 10 includes: a rectangular tubular body part 11 with an open upper and lower surface, an upper panel 12 covering the upper surface of the body part 11, and a foot rest 13 supporting the body part 11. An inlet 14 for laundry is formed in the upper panel 12. The inlet 14 is covered with an upper cover 15 that can be opened and closed.

The drive unit 30 includes a drive motor 31 and a transmission mechanism portion 32. The transmission mechanism unit 32 has a clutch mechanism 32a, and by switching operation of the clutch mechanism 32a, the torque of the drive motor 31 is transmitted only to the pulsator 24 to rotate only the pulsator 24 in the washing process and the rinsing process, and the torque of the drive motor 31 is transmitted to the pulsator 24 and the washing and dehydrating tub 22 to rotate the pulsator 24 and the washing and dehydrating tub 22 integrally.

A drain port 20a is formed at an outer bottom of the outer tub 20. A drain valve 40 is provided in the drain port portion 20 a. The drain valve 40 is connected to a drain hose 41. When the drain valve 40 is opened, the water accumulated in the washing and dehydrating tub 22 and the outer tub 20 is discharged to the outside of the machine through the drain hose 41.

A water supply unit 50 for supplying tap water into the washing and dehydrating tub 22 is disposed at the rear of the upper panel 12.

Fig. 2 is a schematic diagram showing the structure of the water supply unit 50.

The water supply unit 50 has a water supply valve 51. The water supply valve 51 is a so-called double valve, and has a main valve 52 and a sub valve 53 as electromagnetic valves. The water inlet 51a of the water supply valve 51 is connected to a faucet through a water supply hose not shown. A main water supply line 54 is connected to an outlet of the main valve 52 of the water supply valve 51. The main water supply path 54 has a water inlet 54a located at an upper portion of the washing and dehydrating tub 22.

The water supply unit 50 includes therein an automatic feed mechanism 60 for automatically feeding a liquid detergent, which is one of liquid agents for washing, into the washing and dehydrating tub 22.

The automatic loading mechanism 60 includes: a cartridge unit 61, a three-way valve 62, a sub water supply path 63, a supply pump 64, and a detergent supply path 65. The sub-valve 53 of the water supply valve 51 is also included in the automatic charging mechanism 60. The cartridge unit 61 includes a detergent cartridge 100 and a supply pipe 200. The liquid detergent is stored in the detergent box 100 in a stock solution state. The supply pipe 200 guides the liquid detergent of the detergent box 100 to one inlet of the three-way valve 62.

The sub water supply path 63 is connected to an outlet of the sub valve 53 and the other inlet of the three-way valve 62.

The outlet of the three-way valve 62 is connected to a supply pump 64, and the supply pump 64 is connected to a detergent supply path 65. The detergent supply path 65 has a supply port 65a located at an upper portion of the washing and dehydrating tub 22. The supply pump 64 may be a piston pump, for example.

The three-way valve 62 is switchable between a state in which the supply pipe 200 communicates with the supply pump 64 and a state in which the sub water supply passage 63 communicates with the supply pump 64.

As shown in fig. 1, the detergent box 100 of the automatic loading mechanism 60 is disposed inside the cabinet 10, i.e., the top panel 12. The upper panel 12 is provided with an opening 12b above a charging opening 101 formed in the upper surface of the detergent box 100. The opening 12b is covered with a cover not shown and covered with an upper cover 15 from above the cover. The user can put the liquid detergent into the detergent box 100 through the opening 12b and the input port 101 by opening the upper cover 15 and the cover.

Next, the structure of the cartridge unit 61 including the detergent box 100 will be described in detail.

Fig. 3 is a perspective view of the cartridge unit 61 showing a state before the clogging preventing member 300 is mounted to the detergent box 100. Fig. 4 is a perspective sectional view of the cartridge unit 61 showing a state where the clogging preventing member 300 is mounted to the detergent cartridge 100. Fig. 5 (a) and (b) are a top view and a side sectional view of the detergent box 100, respectively. Fig. 6 (a) to (c) are a front view, a side sectional view, and a top view, respectively, of the clogging member 300. In fig. 4, the solidified liquid detergent is schematically shown by a one-dot chain line ellipse. In fig. 5 (b), a part of the supply pipe 200 is indicated by a one-dot chain line.

The cartridge unit 61 is composed of a detergent cartridge 100, a supply pipe 200, and a filter-integrated clogging preventing member 300. The detergent box 100 corresponds to the box body of the present invention.

Referring to fig. 3, 4, and 5 (a) and (b), the detergent box 100 is formed of, for example, a resin material, and has a box shape long in the front and rear. A circular inlet 101 is formed in the upper surface of the detergent box 100 on the front side. Further, two annular ribs 102 are formed on the upper surface of the detergent box 100 around the input port 101. An annular rib, not shown, formed on the back side of the upper surface of the upper panel 12 enters between the two ribs 102, thereby forming a labyrinth seal structure. By this sealing structure, the liquid detergent can be prevented from entering the inside of the upper panel 12.

A filter housing 103 having a cylindrical shape with a substantially closed bottom is formed inside the inlet 101. The front portion of the peripheral surface of the filter housing portion 103 is recessed rearward to form a flat surface except for the upper end portion, and the peripheral surface has a tapered shape slightly expanding upward. Further, a plurality of vertically long slit-shaped holes 104 are formed in the peripheral surface of the filter housing portion 103 on both the left and right sides of the lower portion. A circular opening 105 with a missing front portion is formed in the bottom surface of the filter housing portion 103.

A circular discharge hole 106 and a discharge port 107 connected to the discharge hole 106 are provided in the bottom surface of the detergent box 100 at substantially right positions of the input port 101 and the filter housing part 103. The discharge port 107 has a shape extending downward from the discharge hole 106 and then bending rearward, and is composed of a cylindrical first pipe 108 with a bottom and a cylindrical second pipe 109 protruding rearward from the rear side of the circumferential surface of the first pipe 108. A first flow path 108a is formed in the first pipe 108 in the vertical direction, and a second flow path 109a is formed in the second pipe 109 in the front-rear direction, i.e., in the lateral direction. The first channel 108a and the second channel 109a constitute a channel 107a of the discharge port 107. As shown in fig. 5 (b), the second pipe portion 109 of the discharge port portion 107 is connected to the supply pipe 200.

The detergent box 100 has mounting pieces 110 having mounting holes 110a formed on the front, right and rear sides thereof. The mounting piece 110 is used when the detergent box 100 is fixed to the upper panel 12.

Referring to fig. 3, 4, and 6 (a), (b), and (c), the clogging preventing member 300 is formed of, for example, a resin material, and includes a filter portion 310 and an clogging preventing portion 320 integrated with the filter portion 310.

The filter unit 310 is formed in a substantially bottomed cylindrical shape, and a front portion of a peripheral surface thereof is recessed rearward except for an upper end portion, thereby forming a flat front surface 310a and a flat stepped surface 310b orthogonal to the front surface 310a at the front portion. A handle hole 311 for hooking a finger is formed at an upper portion of the front surface 310a of the filter part 310. The peripheral surface of the filter part 310 has a tapered shape slightly expanding upward, and the angle of expansion is increased at the upper end thereof to easily receive the liquid detergent.

A plurality of first holes 312 in the form of long slits are formed in the filter portion 310 so as to be aligned in the circumferential direction at the corner between the peripheral surface and the bottom surface. A plurality of small circular second holes 313 are formed in the bottom surface of the filter unit 310.

The anti-clogging portion 320 includes a rib 321 extending downward from the bottom surface of the filter portion 310 and having a cross-sectional shape, and a disc-shaped receiving portion 322 formed at the tip of the rib 321. Two right and left rectangular flow ports 323 penetrating in the front-rear direction are formed in the tip end portions of the ribs 321.

As shown in fig. 3, the anti-clogging member 300 is inserted into the detergent box 100 from the input port 101. At this time, the anti-blocking part 320 passes through the opening 105 of the filter accommodating part 103 and enters the inside of the detergent box 100.

When the clogging preventing member 300 is completely inserted into the detergent box 100, that is, when the attachment of the clogging preventing member 300 to the detergent box 100 is completed, as shown in fig. 4, the filter portion 310 is housed in the filter housing portion 103, and the tip end portion of the clogging preventing portion 320 enters the flow path 107a of the discharge port portion 107, that is, the first flow path 108 a. The lower end surface of the first flow path 108a is covered from above by the receiving portion 322 of the anti-clogging portion 320. The two flow ports 323 of the anti-clogging portion 320 are located in front of the inlet of the second flow path 109a to the discharge port portion 107.

The liquid detergent is previously put into the detergent box 100 from the input port 101 by the user. The introduced liquid detergent flows into the detergent box 100 through the first and

second holes

312 and 313 of the filter part 310 and the holes 104 and the opening 105 of the filter accommodating part 103.

The input port 101 has a relatively large opening area so that the liquid detergent can be easily input. Therefore, foreign matter may be erroneously introduced into the detergent box 100 from the inlet 101 when a liquid detergent is introduced. The foreign substances introduced into the detergent box 100 are captured by the filter part 310 without passing through the first and

second holes

312 and 313 of the filter part 310.

The full automatic washing machine 1 performs washing operations in various operation modes. In the washing operation, a washing process, an intermediate dehydration process, a rinsing process, and a final dehydration process are sequentially performed.

In the washing process and the rinsing process, the pulsator 24 rotates right and left in a state that water is accumulated in the washing and dehydrating tub 22. By the rotation of the pulsator 24, a water current is generated in the washing and dehydrating tub 22. In the washing process, the laundry is washed by the generated water flow and the detergent contained in the water. In the rinsing process, the laundry is rinsed by the generated water current.

In the intermediate dehydration process and the final dehydration process, the washing dehydration tub 22 and the pulsator 24 are integrally rotated at a high speed. The laundry is dehydrated by the centrifugal force generated in the washing and dehydrating tub 22.

During the water supply in the washing process, the liquid detergent is automatically supplied into the washing and dehydrating tub 22 by the automatic supply mechanism 60. At this time, first, the three-way valve 62 is switched to a state in which the supply pipe 200 and the supply pump 64 are communicated with each other. When the supply pump 64 is operated, the liquid detergent in the detergent box 100 is discharged from the discharge port 107 by the action of the pump. At this time, in the first flow channel 108a of the discharge port 107, the liquid detergent flowing in front of the flow port 323 of the rib 321 reaches the inlet of the second flow channel 109a through the flow port 323.

The liquid detergent discharged from the discharge port 107 is sent to the detergent supply path 65 through the supply pipe 200, the three-way valve 62, and the supply pump 64 as indicated by the broken line arrow in fig. 2. The supply pump 64 is operated for a predetermined time, and a predetermined amount of liquid detergent is stored in the detergent supply path 65.

Subsequently, the three-way valve 62 is switched to a state in which the sub water supply passage 63 and the supply pump 64 are communicated, and the sub valve 53 is opened. As shown by solid arrows in fig. 2, water from the faucet flows through the sub water supply path 63, the three-way valve 62, and the supply pump 64 to the detergent supply path 65, and washes away the liquid detergent. The liquid detergent flushed by the water is fed into the washing and dehydrating tub 22 from the supply port 65a of the detergent supply path 65 together with the water, as indicated by the one-dot chain line arrow in fig. 2. When the input of the liquid detergent into the washing and dehydrating tub 22 is completed, the sub-valve 53 is closed.

Then, water supply into the washing and dehydrating tub 22 is performed. The main valve 52 is opened, and water from the faucet is discharged from the water inlet 54a into the washing and dehydrating tub 22 through the main water supply path 54. When the water level in the washing and dehydrating tub 22 reaches a predetermined washing water level, the main valve 52 is closed, and the water supply is terminated.

Then, during the use of the full automatic washing machine 1, the solidified liquid detergent may accumulate in the flow path 107a of the discharge port 107 of the detergent box 100, i.e., in the first flow path 108 a. For example, when the detergent box 100 is left empty for a long period of time, the liquid detergent remaining in the first flow path 108a is likely to be solidified into a gel state by long-term contact with air, and if such a situation repeatedly occurs, the solidified liquid detergent gradually increases, and the first flow path 108a is clogged.

In the present embodiment, the distal end portion of the blockage prevention portion 320 enters the first flow path 108 a. Therefore, as shown by the one-dot chain line in fig. 4, the solidified liquid detergent adheres to the rib 321 or accumulates on the receiving portion 322 to be captured by the tip portion of the anti-clogging portion 320. That is, the tip portion of the anti-clogging portion 320 functions as a trap portion for the solidified liquid detergent.

In this way, when the solidified liquid detergent blocks the flow path 107a of the discharge port 107, i.e., the first flow path 108a, the user lifts the anti-clogging member 300 upward and removes it from the detergent box 100. At this time, the user can grasp the clogging member 300 by hooking the handle hole 311 with the fingers and grasping the upper end portion of the filter portion 310.

When the clogging preventing member 300 is detached from the detergent box 100, the top end portion of the clogging preventing portion 320 is taken out to the outside together with the solidified liquid detergent. Thereby, the solidified liquid detergent is removed from the first flow path 108 a. Then, by washing the tip end portion of the anti-clogging portion 320, the solidified liquid detergent is removed from the tip end portion.

When the cleaning of the clogging member 300 is finished, the user mounts the cleaned clogging member 300 to the detergent box 100.

< effects of the embodiment >

As described above, according to the present embodiment, the automatic feed mechanism 60 includes the blocking prevention member 300. The clogging prevention member 300 is inserted into the detergent box 100 from the outside of the casing 10 in an accessible manner, and in the inserted state, the top end portion of the clogging prevention member 300 enters the flow path 107a of the discharge port portion 107, and the liquid detergent solidified in the flow path 107a is captured by the top end portion of the clogging prevention member 300. Thus, when the solidified liquid detergent is accumulated in the flow path 107a of the discharge port 107, the solidified liquid detergent can be easily removed from the outside of the fully automatic washing machine 1, and clogging of the discharge port 107 can be easily prevented.

Further, according to the present embodiment, the clogging preventing member 300 is constituted by the filter portion 310 which is detachably attached to the inlet 101 and captures foreign matters entering the detergent box 100 from the inlet 101, and the clogging preventing portion 320 which is integrated with the filter portion 310 and captures solidified liquid detergent at the tip end portion thereof. This prevents foreign matter from entering the detergent box 100 through the inlet 101. Further, the tip end of the clogging preventing section 320 can be provided in the flow path 107a of the discharge port 107 only by attaching the filter section 310 to the inlet 101. Further, the inlet 101 for introducing the liquid detergent can be used as an insertion opening into which the blocking prevention member 300 is inserted into the detergent box 100.

Further, according to the present embodiment, the following configuration is adopted: the discharge port 107 extends downward from the bottom surface of the detergent box 100, is bent laterally, and has a vertical first flow path 108a and a lateral second flow path 109a, and the distal end of the blockage prevention unit 320 enters the first flow path 108a from above, and has a receiving unit 322 at the distal end thereof that covers the lower end surface of the first flow path 108a from above. Accordingly, the liquid detergent solidified in the first flow path 108a can be received from below by the receiving portion 322, and therefore, when the distal end portion of the clogging prevention portion 320 is lifted up in the first flow path 108a, the solidified liquid detergent is less likely to fall from the distal end portion. Therefore, it is easy to recover the solidified liquid detergent through the clogging member 300.

While the embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments, and various modifications other than those described above may be made to the embodiments of the present invention.

For example, the above embodiment employs the following configuration: the anti-clogging portion 320 of the anti-clogging member 300 includes a cross-shaped rib 321 and a disc-shaped receiving portion 322 formed at the tip of the rib 321. However, the anti-clogging portion 320 may have a structure different from the above structure as long as it can trap the solidified liquid detergent at the tip end portion thereof.

For example, in the configuration example of fig. 7 (a), the clogging member 300A has the clogging preventing portion 330 integrated with the filter portion 310. The anti-blocking portion 330 is composed of a cylindrical body portion 331 and a disk-shaped bottom portion 332 that blocks the opening of the bottom surface of the body portion 331. The bottom portion 332 corresponds to a receiving portion of the present invention. An opening 333 is formed on the rear side of the lower end of the main body 331. The opening 333 faces the inlet of the second channel 109 a. The body 331 is formed with a plurality of rectangular flow ports 334. The liquid detergent, which is introduced from the introduction port 101 and flows out from the second hole 313 of the filter unit 310 into the anti-clogging unit 330, flows into the detergent box 100 through the flow port 334. Further, a part of the liquid detergent in the detergent box 100 flows through the flow port 334 into the blocking-preventing part 330, and flows through the opening part 333 into the second flow path 109 a.

In the clogging preventing member 300A of fig. 7 (a), the liquid detergent solidified in the first flow path 108a can be captured by the distal end portion of the clogging preventing portion 330.

In the above embodiment, the clogging preventing member 300 is configured such that the clogging preventing portion 320 and the filter portion 310 are integrated. However, as shown in the example of fig. 7 (B), the blocking prevention member 300B may be configured without a filter unit.

In the configuration example of fig. 7 (b), the filter unit 310 is provided as a separate filter member 310 and is housed in the filter housing portion 103 of the detergent box 100A. In the detergent box 100A, the outlet 107 is formed behind the filter housing 103. Further, a circular insertion opening 111 is formed in the upper surface of the detergent box 100A at the rear of the input opening 101.

The plug member 300B is composed of a plug 340 and a cap 350 that plugs the insertion port 111. The anti-clogging portion 340 includes a rib 341 extending downward from the bottom surface of the cap portion 350 and having a cross-sectional shape, and a disk-shaped receiving portion 342 formed at the tip of the rib 341. Two right and left square flow ports 343 penetrating in the front-rear direction are formed in the tip end portions of the ribs 341. A knob 351 is provided on the upper surface of the cap 350. When the clogging preventing member 300B is inserted into the detergent box 100 from the insertion port 111, the top end portion of the clogging preventing portion 340 enters the first flow path 108a of the discharge port portion 107.

In the clogging preventing member 300B of fig. 7 (B), the liquid detergent solidified in the first flow path 108a can be captured by the tip end portion of the clogging preventing portion 340.

Further, although the detergent box 100 is disposed at the rear left end portion of the inside of the upper panel 12 in the above embodiment, it may be disposed at another position. The detergent box 100 may be disposed inside the cabinet 10 other than the upper panel 12.

Further, in the above embodiment, the automatic supply mechanism 60 is configured to include the detergent box 100 in the box unit 61 and automatically supply the liquid detergent stored in the detergent box 100. However, the automatic supply mechanism 60 may be configured to include a softener box in the box unit 61, which stores a liquid softener, which is a kind of liquid agent for washing, instead of the detergent box 100 or together with the detergent box 100, and automatically supply the liquid softener in the softener box, which has the anti-clogging member 300, as in the detergent box 100.

Further, in the above embodiment, the discharge port 107 is bent in an L shape, and the flow path 107a is also bent in an L shape, that is, includes the first flow path 108a in the vertical direction and the second flow path 109a in the lateral direction. However, the discharge port 107 and the flow path 107a may be linear. In this case, if the socket 322 is provided at the distal end of the plug 320, which is the plug member 300, the flow path 107a is easily blocked by the socket 322. Therefore, in this case, the receiving portion 322 may not be provided at the distal end portion of the anti-clogging portion 320.

Further, in the above embodiment, the fully automatic washing machine 1 is illustrated as an example of a washing machine provided with the automatic loading mechanism 60. However, the present invention can be applied to washing machines other than the full automatic washing machine 1, such as a full automatic washer-dryer, a drum type washing machine, a drum type washer-dryer, and the like. In a drum-type washing machine and a drum-type washing and drying machine, a washing tub is composed of an outer tub and a drum disposed in the outer tub.

In addition, the embodiment of the present invention can be modified in various ways as appropriate within the scope of the technical idea shown in the claims.
