A user can fold the outer lid 3 and open the upper part of the washing machine 1 by grasping and pulling up the grip portion 3e (see FIG. 3) of the front lid 3a (see the two-dot chain line in FIG. 4).

[0012] An operation unit 5 (see FIGS. 3 and 4) operated by a user when operating the washing machine 1 is provided on the front upper part of the washing machine 1.

[0013] As shown in Figure 4, the washing machine 1 has a bottomed cylindrical outer tub 6 inside the housing 1k. The outer tub 6 is formed in a bottomed cylindrical shape with an opening 6a1 at the top. An inner tank 7 is provided coaxially inside the outer tank 6. The inner tank 7 has a bottomed cylindrical shape with an open top. Numerous small dewatering holes 7a are provided on the side circumference 7s of the inner tank 7. The outer tank 6 has a cylindrical body plate 6d with an axis in a substantially vertical direction and a bottom plate 6s that forms the bottom surface. A rotor blade 8 that rotates during washing and rinsing is provided above the bottom plate 6s of the outer tub 6.

[0014] The outer tank 6 has an outer tank cover 6a and an inner lid 6b on its upper surface. The inner lid 6b closes the opening 6a1 provided in the outer tank cover 6a. A drain outlet 6h is formed at the bottom of the outer tank 6. A balance ring 6c, which acts as a fluid balancer, is installed at the upper end of the shell plate 6d of the outer tub 6. The balance ring 6c has fluid sealed inside. During spin-drying, the balance ring 6c reduces vibrations caused by the imbalance of the clothes by moving the fluid to the opposite side of the clothes.

[0015] The washing machine 1 includes a drive unit 9 for rotating the inner tub 7 and the rotor blade 8, and a rotation detection device (not shown) and a motor current detection device (not shown) for detecting the operation of the drive unit 9. The drive unit 9 includes a motor 9a that rotates the inner tank 7 and the rotor blade 8, a clutch mechanism 9b that defines the rotation mode (agitation, dewatering) of the rotor blade 8 and the inner tank 7, and a rotating shaft 9c connected to the rotor blade 8. The rotating shaft 9c is located at the center of the outer tank 6 when viewed from above.

[0016] As shown in Figure 4, the washing machine 1 is equipped with a water supply unit 10 at the rear upper part that supplies water to the outer tub 6.

[0017] <Control circuit board 19> The rear of the washing machine 1, as shown in Figure 4, is equipped with a control circuit board 19 for controlling the washing machine 1. The control circuit board 19 includes a microcomputer, a drive circuit, and a sensor circuit. The drive circuit controls the motor 9a, the clutch mechanism 9b, and various valves. The sensor circuit controls a temperature sensor (not shown), a water quality sensor (not shown), and the like. The temperature sensor detects the temperature of the wash water. The water quality sensor detects the hardness of the wash water and the amount of detergent in the wash water.

[0018] Figure 5 shows a perspective view of the washing machine 1 with the outer lid 3 removed, as seen from the front and above, as indicated by the arrow in direction I in Figure 4. Figure 6 shows a perspective view of the washing machine 1 with the outer lid 3 removed, viewed from the upper right front. A washing liquid dispensing device 11 is provided at the upper rear of the washing machine 1, which dispenses detergent into the outer tub 6 during washing and fabric softener, etc., into the outer tub 6 during rinsing.

[0019] <Laundry liquid dispensing device 11> The laundry liquid dispensing device 11 shown in Figure 6 has a detergent tank 11a and a fabric softener tank 11b at the top, and manual dispensing cases 11c for detergent and fabric softener at the bottom. As shown in Figure 3, the detergent tank 11a and the fabric softener tank 11b are located on the outside of the outer lid 3. The manual dispensing case 11c includes a manual detergent dispensing case 11d and a manual fabric softener dispensing case 11e. In other words, the manual dispensing ports for detergent and fabric softener are combined into a single manual dispensing case 11c.

[0020] The laundry liquid dispensing device 11 matches the arrangement of detergent and fabric softener in the tanks (11a, 11b) to the arrangement of detergent and fabric softener in the manual dispensing case 11c. In other words, in the tanks (11a, 11b) and the manual dispensing case 11c, the detergent tank (11a) and case (11d) are located on the left side, and the fabric softener tank (11b) and case (11e) are located on the right side.

[0021] The upper ends of the detergent tank 11a and the fabric softener tank 11b shown in Figure 6 are open upwards, and are provided with a detergent tank lid 11a2 and a fabric softener tank lid 11b2 that can be opened and closed. The detergent tank 11a is pre-filled with liquid detergent by the user, and the liquid detergent is automatically dispensed into the outer tub 6 when washing begins. The fabric softener tank 11b is pre-filled with liquid fabric softener by the user, and the liquid fabric softener is automatically dispensed into the outer tub 6 during the rinse cycle.

[0022] As shown in Figure 3, the detergent tank 11a and the fabric softener tank 11b are exposed to the outside when the outer lid 3 is closed. Therefore, the user can visually inspect the detergent tank 11a and the fabric softener tank 11b when the outer lid 3 is closed. The detergent tank 11a has a viewing window 11a1 on its top surface. Therefore, the user can check the amount of detergent by looking through the viewing window 11a1. If the amount of detergent in the detergent tank 11a is low, the user can open the detergent tank lid 11a2 and refill it with liquid detergent. After that, closing the detergent tank lid 11a2 seals the detergent tank 11a.

[0023] The fabric softener tank 11b has a viewing window 11b1 on its top surface. Therefore, the amount of detergent can be checked by looking through the viewing window 11b1. If the amount of fabric softener in the fabric softener tank 11b is low, the fabric softener tank lid 11b2 can be opened to replenish the liquid fabric softener. When the fabric softener tank lid 11b2 is closed, the fabric softener tank 11b is sealed. The detergent tank 11a and the fabric softener tank 11b each contain enough liquid detergent and fabric softener for multiple washes. The laundry liquid dispensing device 11, under the control of the control circuit board 19, measures the laundry liquid contained in the detergent tank 11a and the fabric softener tank 11b and automatically dispenses the appropriate amount of laundry liquid into the outer tub 6. For this reason, the laundry liquid dispensing device 11 is equipped with an automatic dispensing unit 15 (see Figure 12) that measures the laundry liquid and transports it from the detergent tank 11a and the fabric softener tank 11b to the outer tub 6.

[0024] <Manual detergent dispenser 11d and manual fabric softener dispenser 11e for manual dispenser 11c> The manual dispensing case 11c shown in Figure 6 has a manual detergent dispensing case 11d on the left and a manual fabric softener dispensing case 11e on the right. The manual detergent dispenser case 11d and the manual fabric softener dispenser case 11e function as manual dispensers for the user to manually dispense powder detergent, liquid detergent, bleach, and fabric softener (finishing agent) into the outer tub 6 (see Figure 4), respectively.

[0025] The manual detergent dispenser 11d is for the user to manually add powdered detergent, liquid detergent, and bleach. The manual fabric softener dispenser 11e is for the user to manually add fabric softener. When the user wants to add powdered detergent, liquid detergent, or bleach, as shown in Figure 6, the user pulls out the manual dispensing case 11c and puts the powdered detergent, liquid detergent, or bleach into the manual detergent dispensing case 11d on the left. When the user adds fabric softener (finishing agent), as shown in Figure 6, the user pulls out the manual dispenser case 11c and puts the fabric softener into the manual fabric softener dispenser case 11e on the right.

[0026] <Detergent tank 11a on the left and fabric softener tank 11b on the right> As shown in Figure 6, when viewed from the washing machine 1, the detergent tank 11a is located on the left and the fabric softener tank 11b is located on the right.

[0027] As shown in Figures 5 and 6, with the manual dispensing case 11c closed, the manual dispensing case 11c is located below the fabric softener tank 11b in a vertical line. Below the fabric softener tank 11b, the manual dispensing case 11c has, when viewed from the washing machine 1, a manual detergent dispensing case 11d on the left and a manual fabric softener dispensing case 11e on the right.

[0028] In other words, the detergent-related components (detergent tank 11a and manual detergent dispenser 11d) are located on the left side, and the fabric softener-related components (fabric softener tank 11b and manual fabric softener dispenser 11e) are located on the right side. Therefore, the user will find it easy to understand and use, as the respective dispensing locations for detergent and fabric softener are aligned on the left and right sides, respectively. In addition, there are two possible combinations: (1) when the manual detergent dispenser 11d and the manual fabric softener dispenser 11e are arranged side by side below (vertically below) the detergent tank 11a, and (2) when the manual detergent dispenser 11d and the manual fabric softener dispenser 11e are arranged side by side below (vertically below) the fabric softener tank 11b. In this embodiment, case (2) is illustrated (an example where the manual detergent dispenser 11d is on the left and the manual fabric softener dispenser 11e is on the right).

[0029] As shown in Figure 3 of the top view, the top surface of the washing machine 1 is provided with a water tap connection port 2a and a bath water tap connection port 2b. Figure 7 shows a top view of the rear of the washing machine 1 with the top cover 2, detergent tank 11a, and fabric softener tank 11b removed. A water supply valve 12a for detergent and a water supply valve 12b for fabric softener, which are connected to the faucet connection port 2a and the bath faucet connection port 2b respectively, are provided below the top cover 2 (see Figure 4). A water supply box 13 is provided in front of the detergent water supply valve 12a and the fabric softener water supply valve 12b.

[0030] <Water supply box 13> The water supply box 13 shown in Figure 7 supplies water to the manual detergent dispenser 11d and the manual fabric softener dispenser 11e, respectively. The top of the water supply box 13 is fitted with a water supply box lid 13a.

[0031] Below the water supply box 13 are a manual detergent dispenser 11d and a manual fabric softener dispenser 11e, which supply water from the water supply box 13. A bath water pump 14 is installed near the lower part of the bath faucet connection port 2b, and is connected to the bath faucet connection port 2b. The bath water pump 14 draws up bath water through the bath faucet connection port 2b.

[0032] On the left side of the water supply box 13, there are detergent nozzles 15a and fabric softener nozzles 15b, which are inserted into the detergent tank 11a and the fabric softener tank 11b, respectively. An automatic dispensing unit 15 is provided to the left of the detergent nozzle 15a and the fabric softener nozzle 15b. The automatic dispensing unit 15 is responsible for dispensing liquid detergent from the detergent tank 11a into the water quality, temperature, and detergent detection tank 6k (see Figure 9) and the outer tank 6, as well as dispensing liquid fabric softener from the fabric softener tank 11b into the water quality, temperature, and detergent detection tank 6k (see Figure 9) and the outer tank 6.

[0033] Figure 8 shows a top view of the washing machine 1 with the top cover 2, detergent tank 11a, fabric softener tank 11b, and water supply box lid 13a (see Figure 7) removed. Below the water supply box lid 13a (see Figure 7), there is a manual detergent case channel 16a, a manual fabric softener case channel 16b, an automatic dispensing channel 16c, and a main water supply channel 16d. The manual detergent case flow path 16a is a flow path for supplying water from the detergent water supply valve 12a to the manual detergent dispenser case 11d (see Figure 6) in order to flush out powder detergent, liquid detergent, and bleach from the manual detergent dispenser case 11d.

[0034] The manual fabric softener case flow path 16b is a flow path for supplying water from the fabric softener water supply valve 12b to the manual fabric softener dispenser case 11e (see Figure 6) in order to flush out the fabric softener from the manual fabric softener dispenser case 11e. The automatic dispensing channel 16c is a channel for supplying water from the detergent water supply valve 12a to the hose 15h (see Figure 12) of the automatic dispensing unit 15 in order to dispense liquid detergent from the detergent tank 11a or liquid fabric softener from the fabric softener tank 11b. The main water supply channel 16d is the channel that supplies water to the outer tank 6.

[0035] <Manual detergent dispenser flow path 16a> During washing, the washing water supplied from the detergent water supply valve 12a (arrow α11 in Figure 8) flows through the manual detergent case flow path 16a, as shown by arrow α12 in Figure 8.

[0036] The water indicated by arrow α12 in Figure 8 is supplied from the detergent dispenser opening 16a1 to the manual detergent dispenser case 11d (arrow α14 in Figure 9). Figure 9 shows the II-II cross-sectional view of Figure 8.

[0037] Figure 10 shows the section III-III in Figure 9. As shown by arrow α14 in Figures 9 and 10, the water that flows from the detergent case inlet 16a1 to the manual detergent dispensing case 11d flows through the manual detergent dispensing case 11d, pushing the powdered detergent, liquid detergent, and bleach along with the laundry water (arrow α15 in Figures 9 and 10), and the powdered detergent, liquid detergent, and bleach are then dispensed together with the laundry water from the detergent dispensing hole 17a into the water quality, temperature, and detergent detection tank 6k (arrow α16 in Figures 9 and 10).

[0038] The water indicated by arrow α13 in Figure 8 flows from the detergent case inlet 16a2 to the laundry liquid inlet case 11f located below the manual detergent dispenser case 11d shown in Figure 9. The water then flows through the laundry liquid inlet case 11f, pushing away any remaining powdered and liquid detergents and bleach (arrow α17 in Figure 9), and the remaining powdered and liquid detergents and bleach are then introduced into the water quality, temperature, and detergent detection tank 6k through the detergent inlet hole 17a, along with the wash water (arrow α16 in Figure 9). A water quality sensor (not shown) and a temperature sensor are installed inside the 6k water quality, temperature, and detergent detection tank.

[0039] The water quality sensor detects the hardness (whether it's hard or soft water) of the wash water based on its conductivity, as well as the type and amount of detergent used. The temperature sensor detects the temperature of the wash water and rinse water. After detection, the wash water and detergent from the water quality, temperature, and detergent detection tank 6k are supplied to the outer tank 6. Based on the readings from the water quality sensor and temperature sensor, the AI ​​can perform washing that is appropriate for the amount of laundry, the water quality of the wash water, and the type and amount of detergent used.

[0040] <Main water supply channel 16d> The water supplied from the detergent water supply valve 12a shown in Figure 8 is supplied to the outer tank 6 through the main water supply channel 16d, as indicated by arrow γ21 in Figure 8.

[0041] <Manual fabric softener dispenser channel 16b> During rinsing, the rinse water supplied from the fabric softener water supply valve 12b shown in Figure 8 (arrow β11 in Figure 8) flows through the manual fabric softener case channel 16b, as shown by arrows β12 and β13 in Figure 8. The water indicated by arrow β12 in Figure 8 is supplied from the fabric softener dispenser opening 16b1 to the manual fabric softener dispenser 11e (arrow β14 in Figures 10 and 11). Figure 11 shows the section IV-IV of Figure 8.

[0042] Water flowing from the fabric softener dispenser opening 16b1 into the manual fabric softener dispenser 11e (arrow β14 in Figures 11 and 10) flows through the manual fabric softener dispenser 11e, pushing the fabric softener along (arrow β15 in Figures 11 and 10), and the fabric softener and rinse water are then dispensed from the detergent dispenser hole 17a into the water quality, temperature, and detergent detection tank 6k (arrow β16 in Figure 11).

[0043] The water indicated by arrow β13 in Figure 8 flows from the fabric softener dispenser opening 16b2 to the laundry liquid dispenser case 11f shown in Figure 11. Then, it flows through the laundry liquid dispenser case 11f, pushing out any remaining fabric softener (arrow β17 in Figure 11), and the fabric softener is added to the water quality, temperature, and detergent detection tank 6k from the detergent dispenser hole 17a along with the rinse water (arrow β16 in Figure 11). After the rinse water and fabric softener are detected, the rinse water and fabric softener from the water quality, temperature, and detergent detection tank 6k are supplied to the outer tank 6.

[0044] <Automatic feeding channel 16c> The water supplied from the detergent water supply valve 12a shown in Figure 8 (arrow γ11 in Figure 8) flows through the automatic dispensing channel 16c, as shown by arrow γ12 in Figure 8.

[0045] The water indicated by arrow γ12 in Figure 8 is supplied from the tank inlet 16c1 to the automatic supply hose 15h of the automatic supply unit 15 (see Figure 12) (arrow γ13 in Figure 12).

[0046] <Automatic feeding unit 15> Figure 12 shows a perspective view of the upper rear of the washing machine 1 (see Figures 1 and 4) with the top cover 2, detergent tank 11a, and fabric softener tank 11b removed, viewed from an oblique angle above and behind. The detergent nozzle 15a is connected to the detergent tank 11a (see Figure 6). The fabric softener nozzle 15b is connected to the fabric softener tank 11b (see Figure 6).

[0047] When dispensing liquid detergent from the detergent tank 11a shown in Figure 6, the liquid detergent is supplied from the detergent tank 11a to the automatic dispensing hose 15h (see Figure 12) by pulling and pushing a piston (not shown) provided in the automatic dispensing unit 15 shown in Figure 12. The liquid detergent supplied to the automatic dispensing hose 15h is supplied from the tank inlet 16c1 (see Figure 8) to the automatic dispensing hose 15h (see Figure 12) via water flowing through the automatic dispensing channel 16c from the detergent water supply valve 12a (arrow γ12 in Figure 8). The liquid detergent, along with the water, then flows through the automatic dispensing hose 15h (arrow γ13 in Figure 12) to the detergent dispensing hole 17a, as shown by arrow γ14 in Figure 12.

[0048] When dispensing liquid fabric softener from the fabric softener tank 11b shown in Figure 6, the liquid fabric softener is supplied from the fabric softener tank 11b to the automatic dispensing hose 15h (see Figure 12) by pulling and pushing a piston (not shown) provided in the automatic dispensing unit 15. The liquid fabric softener supplied to the automatic dispensing hose 15h is supplied by water flowing through the automatic dispensing channel 16c from the detergent water supply valve 12a shown by arrow γ12 in Figure 8 (arrow γ12 in Figure 8), which is supplied to the automatic dispensing hose 15h (see Figure 12) from the tank inlet 16c1 (see Figure 8). The liquid fabric softener, together with the water, then flows through the automatic dispensing hose 15h (arrow γ13 in Figure 12) to the detergent dispensing hole 17a, as shown by arrow γ14 in Figure 12.

[0049] <Manual dispensing case 11c and detergent dispensing hole 17a (see Figure 10)> Figure 13A shows a perspective view of the manual input case 11c from the upper right front. Figure 13B shows a top view of the manual input case 11c from above. As described above, the manual dispensing case 11c includes a manual detergent dispensing case 11d and a manual fabric softener dispensing case 11e. The manual detergent dispenser case 11d is formed in a vertically elongated concave case shape in the front-to-back direction, with a bottom plate 11d3 that is inclined so that the back side is positioned downwards. The back side of the manual detergent dispenser case 11d has a grid section 11d2 that has notches 11d1 which are holes. As a result, when powdered detergent, liquid detergent, or bleach is placed in the manual detergent dispenser case 11d, the powdered detergent, liquid detergent, or bleach moves along the bottom plate 11d3 towards the notch 11d1 of the grid section 11d2, allowing the powdered detergent, liquid detergent, or bleach to fall smoothly from the notch 11d1 of the grid section 11d2.

[0050] The manual fabric softener dispenser case 11e, like the manual detergent dispenser case 11d, is formed in a vertically elongated concave case shape in the front-to-back direction, with a bottom plate 11e3 that is inclined so that the back side is located downwards. The back of the manual fabric softener dispenser case 11e is configured as a siphon section 11e1 that supplies fabric softener to the water quality, temperature, and detergent detection tank 6k and the outer tank 6 via a siphon. When adding powdered or liquid detergent, bleach, or fabric softener to the manual dispenser 11c, the user pulls the dispenser 11c forward, as shown in Figure 6. The user then puts the powdered or liquid detergent or bleach into the manual detergent dispenser 11d on the left. The user also puts the fabric softener into the manual fabric softener dispenser 11e on the right. After that, as shown in Figures 5 and 10, the user pushes the manual dispenser 11c back in place. Therefore, when adding detergent or fabric softener, the user can pull out the manual dispenser 11c, add the detergent or fabric softener, and then push it back in to store it.

[0051] Furthermore, as shown in Figure 10, a detergent dispensing hole 17a for dispensing powdered detergent, liquid detergent, and bleach is formed on the extension line in the front-to-back direction of the vertically elongated manual detergent dispensing case 11d. Therefore, as shown by arrows α15 and α16 in Figure 9, powdered detergent, liquid detergent, and bleach can be smoothly dispensed into the detergent dispensing hole 17a. By positioning the detergent dispensing hole 17a perpendicular to the grid section 11d2 having the notch 11d1 of the manual detergent dispensing case 11d, the detergent is more likely to fall into the detergent dispensing hole 17a due to the recoil when the manual dispensing case 11c is pushed in.

[0052] As shown in Figure 10, by positioning the hole (detergent dispensing hole 17a) in the path connecting the manual detergent dispensing case 11d to the outer tub 6 on the extension of the grid section 11d2 having a notch 11d1 in the manual detergent dispensing case 11d, powdered detergent, liquid detergent, and bleach will fall directly from the manual detergent dispensing case 11d into the detergent dispensing hole 17a in the path. As a result, less detergent residue is left in the manual detergent dispenser case 11d (see Figure 10).

[0053] With the above configuration, when adding detergent or fabric softener, the left side of the tanks (11a, 11b) and the manual dispensing case 11c are designated for detergent and the right side for fabric softener, making it less likely for the user to get confused. By eliminating confusion for users regarding where to put detergent and fabric softener, it prevents reduced cleaning power due to incorrect dispensing. It also reduces the effort required for cleaning caused by incorrect dispensing.

[0054] As shown in Figure 10, the notch 11d1 in the grid section 11d2 of the pull-out type manual detergent dispenser case 11d and the detergent dispenser hole 17a in the path leading to the tank (water quality / temperature / detergent detection tank 6k and outer tank 6) are oriented vertically. Therefore, powdered detergent, liquid detergent, and bleach are less likely to remain undissolved in the pull-out manual detergent dispenser 11d. By ensuring that powder and liquid detergents, as well as bleach, are completely rinsed away, the AI ​​washing system (which adjusts washing based on water quality, temperature, detergent type, and clothing soiling) functions correctly. Furthermore, insufficient cleaning due to undissolved powdered and liquid detergents or bleach in the manual detergent dispenser 11d will be eliminated. The hassle of cleaning due to undissolved powdered and liquid detergents or bleach in the manual detergent dispenser 11d will be eliminated.

[0055] <Variation> In the above embodiment, as shown in Figure 10, a detergent dispensing hole 17a for dispensing powdered detergent, liquid detergent, and bleach was formed on the extension line in the front-to-back direction of the manual detergent dispensing case 11d. Figure 14 shows a modified example, corresponding to the section III-III in Figure 9. In contrast, in the modified example shown in Figure 14, the grid portion 11d2 having the notch 11d1 of the manual detergent dispenser case 11d and the detergent dispenser hole 27a are configured to overlap at least partially when viewed from above.

[0056] In the modified version, by providing a detergent input hole 27a below the grid section 11d2 through which powdered detergent, liquid detergent, and bleach flow, the powdered detergent, liquid detergent, and bleach can more easily fall into the tank (water quality, temperature, and detergent detection tank 6k or outer tank 6).

[0057] <<Other Embodiments>> 1. In the above embodiment, the case in which the manual dispensing case 11c is closed and located below the vertical line of the fabric softener tank 11b was described, but the manual dispensing case 11c may also be located below the vertical line of the detergent tank 11a.

[0058] 2. In the above embodiment, the case in which the detergent dispensing hole 17a is directly connected to the water quality, temperature, and detergent detection tank 6k was described, but it is also possible to configure the system so that the detergent dispensing hole 17a is directly connected to the outer tank 6 without performing AI washing.

[0059] 3. In the above embodiment, the case in which the detergent tank 11a, fabric softener tank 11b, and manual dispensing case 11c are located at the rear of the washing machine 1 was described, but the detergent tank 11a, fabric softener tank 11b, and manual dispensing case 11c may be located at the front, right, or left of the washing machine 1.

[0060] 4. In the above embodiment, the case in which the detergent tank 11a and the manual detergent dispenser 11d are arranged on the left side (one side) and the fabric softener tank 11b and the manual fabric softener dispenser 11e are arranged on the right side (the other side) was described. However, the detergent tank 11a and the manual detergent dispenser 11d may be arranged on the right side (the other side) and the fabric softener tank 11b and the manual fabric softener dispenser 11e may be arranged on the left side (one side).
