A plurality of embodiments of the laundry processing apparatus will be described below with reference to the drawings. It should be noted that substantially the same elements in a plurality of embodiments are denoted by the same reference numerals, and descriptions thereof are omitted.

(First embodiment)
A washing machine 1 illustrated in FIG. 1 is an example of a clothing processing apparatus capable of performing predetermined processing on clothing, in this case, at least washing processing, rinsing processing, and spin-drying processing. Moreover, the washing machine 1 is a so-called drum-type washing machine in which the rotation center axis of the rotating tub extends in a horizontal direction or in a direction inclined with respect to the horizontal direction.

The washing machine 1 includes a washing tub 3 for washing clothes inside a rectangular box-shaped housing 2 that constitutes its outer shell. The washing tank 3 has a configuration in which a bottomed cylindrical drum is rotatably provided inside a bottomed cylindrical water tank. The peripheral wall of the drum is provided with a large number of small holes, and the inner peripheral surface of the drum is provided with baffles for raking up the clothes.

The washing machine 1 also includes a water supply section 4 for supplying water into the washing tub 3 and a drain section (not shown) for draining the water in the washing tub 3 to the outside of the washing machine. The water supply unit 4 has a water supply valve 11 and the like in the middle of a water supply path 10 extending from a water source (not shown) such as a water supply to the cleaning tank 3 . Further, the drain section has a drain valve or the like in the middle of the drain path extending from the bottom of the washing tank 3 to the outside of the machine.

Next, a configuration example of the water supply unit 4 described above will be described in more detail. As illustrated in FIG. 2, the water supply unit 4 includes a water supply valve 11, a mixing unit 12, a water injection case 13, a water injection hose 14, and the like in the middle of a water supply path 10 extending from a water source (not shown) to the cleaning tank 3. The water supply valve 11 is composed of, for example, a liquid on-off valve that can be opened and closed electromagnetically. The drain valve provided in the drain section is also composed of, for example, a liquid on-off valve that can be electromagnetically opened and closed. The mixing section 12 is provided in a substantially rectangular case shape.

The water supply path 10 is a path for supplying water from an external water source into the cleaning tank 3. In this case, it mainly includes a water source side path 10A, a mixing section 12, a cleaning tank side path 10B, and a water injection case 13. , and the water injection hose 14 are connected in this order from the upstream side.

The water source side path 10A has an upstream end connected to an external water source and a downstream end connected to the mixing section 12 . That is, the water source side path 10A extends from the external water source and is connected to the mixing section 12 . The cleaning tank-side path 10B has an upstream end connected to the mixing section 12 and a downstream end connected to the water injection case 13 . That is, the cleaning tank-side path 10B extends from the mixing section 12 and is connected to the water injection case 13 . The water injection case 13 is connected to the cleaning tank 3 via a water injection hose 14 .

In this case, the water supply valve 11 is provided in the water supply path 10 in the middle of the water source side path 10A. Therefore, the water supply valve 11 is configured to be located upstream of the mixing section 12 in the water supply path 10 .

Moreover, the water supply unit 4 further includes an automatic detergent injection unit 15 . The detergent automatic input unit 15 includes a detergent supply path 17 connecting the detergent tank 16 and the mixing part 12 and a metering pump 18 provided in the detergent supply path 17 . The detergent supply path 17 is an example of a clothing treatment agent supply path. The detergent supply path 17 is a path for supplying the detergent contained in the detergent tank 16 into the washing tank 3, and its downstream end is located in the middle of the water supply path 10, in this case, the water supply path. It is connected to a mixing section 12 provided in the middle of 10 . That is, the washing machine 1 has a configuration in which the mixing section 12 is provided at a portion where the detergent supply path 17 is connected to the water supply path 10 .

The metering pump 18 is configured to suck and deliver liquid by driving a piston with an actuator such as a motor or a solenoid. The metering pump 18 sucks a predetermined amount of detergent from the detergent tank 16, in this case, the amount used for one operation, and delivers the sucked detergent into the mixing section 12 via the detergent supply path 17. . As a result, a predetermined amount of detergent is automatically introduced into the mixing section 12 .

Also, the washing machine 1 has a configuration in which a water source side path 10A forming part of the water supply path 10 is connected upstream of a portion of the mixing section 12 to which the detergent supply path 17 is connected. In addition, the washing machine 1 is configured such that the washing tank side path 10B, which constitutes part of the water supply path 10, is connected below the portion of the mixing section 12 to which the water source side path 10A is connected. . Further, unlike the water source side path 10A and the washing tank side path 10B which are configured simply as water channels through which water flows, the mixing section 12 is a component having a space having a certain volume. Specifically, in the mixing section 12, the cross-sectional area orthogonal to the direction connecting the upstream side to which the water source side path 10A is connected and the downstream side to which the cleaning tank side path 10B is connected is the extending direction of the water source side path 10A. and the cross-sectional area perpendicular to the extending direction of the cleaning tank-side path 10B. In addition, the mixing section 12 is wider than the water source side path 10A and the cleaning tank side path 10B so that the water does not flow linearly in the mixing section 12 but spreads out to some extent. is an element.

Next, a configuration example of the control system of the washing machine 1 will be described. The control device 30 illustrated in FIG. 3 is mainly composed of a microcomputer, for example, and controls the overall operation of the washing machine 1 based on a control program. The control device 30 is connected to the water supply valve 11 and the metering pump 18 described above, as well as the motor for rotating the drum in the cleaning tank 3, the drain valve of the drain section, and the like. The control device 30 controls the operation of these components of the drive system to perform a known washing process for washing the clothes in the washing tank 3, a known rinsing process for rinsing the clothes in the washing tank 3, Various operations including a well-known dehydration process for dehydrating clothes are configured to be executable.

Next, an example of water supply operation by the washing machine 1 configured as described above will be described. Here, an example of the operation of supplying water together with the detergent into the washing tank 3 in the washing process will be described. When the water supply operation is started, the control device 30 of the washing machine 1 opens the water supply valve 11 to supply water from an external water source into the washing tub 3 through the water supply path 10 . The control device 30 also drives the metering pump 18 to feed a predetermined amount of detergent from the detergent tank 16 into the mixing section 12 .

As a result, the water supplied from the external water source and the detergent supplied from the detergent tank 16 coexist in the mixing section 12 . Then, in the mixing section 12, water is continuously supplied from the external water source, so that a water flow is generated. Thereby, the water and the detergent are mixed in the mixing section 12 . The water mixed with the detergent in the mixing unit 12 flows into the water injection case 13 from the cleaning tank side path 10B, and further flows from inside the water injection case 13 into the cleaning tank 3 via the water injection hose 14 . As a result, the water containing the detergent sufficiently mixed in the mixing section 12 is supplied into the cleaning tank 3 .

According to the washing machine 1, the mixing section 12 is provided at the portion where the detergent supply path 17 is connected to the water supply path 10. The mixing part 12 mixes the water supplied through the water supply path 10 and the detergent supply path 17. The supplied detergent is sufficiently mixed before being supplied into the washing tank 3 . Therefore, the detergent can be sufficiently mixed with water and then supplied into the washing tank 3, so that the washing effect of the detergent on the clothes can be exhibited sufficiently. Further, according to the washing machine 1, the mixing section 12 is provided not only as a channel through which water flows, but as a component having a space having a certain volume. Therefore, the water supplied into the mixing section 12 flows with a certain width in the mixing section 12, thereby further promoting the mixing of the water and the detergent. Note that the mixing section 12 is not limited to a rectangular shape as long as it has a cross-sectional area larger than that of the water source side path 10A and the cleaning tank side path 10B, and can be configured in various shapes such as a cylindrical shape, for example. .

Further, according to the washing machine 1, the water supply path 10 has a configuration in which the water source side path 10A and the washing tank side path 10B are connected to the mixing section 12. As shown in FIG. That is, since the mixing section 12 is provided in the middle of the water supply path 10, the water and the detergent can be mixed in the mixing section 12 in the process of the water flowing through the water supply path 10. The flow of water through path 10 can be used to increase the mixing efficiency of water and detergent.

Further, according to the washing machine 1, the water source side path 10A is connected upstream of the portion of the mixing section 12 to which the detergent supply path 17 is connected. That is, the water source side path 10A that supplies water into the mixing section 12 is connected upstream of the detergent supply path 17 that supplies detergent into the mixing section 12 . Therefore, the detergent supplied into the mixing section 12 can be efficiently flowed from the inside of the mixing section 12 to the cleaning tank 3 side by the water supplied into the mixing section 12 .

Further, according to the washing machine 1, the washing-tub-side path 10B is connected below the portion of the mixing section 12 to which the water-source-side path 10A is connected. That is, the outlet of water from inside the mixing section 12 is provided at a position lower than the inlet of water into the mixing section 12 . Therefore, the water that has flowed into the mixing section 12 is more likely to flow out of the mixing section 12, and it is possible to prevent the water that has once flowed into the mixing section 12 from flowing backward to the upstream side. In addition, since the inlet of the water into the mixing section 12 is provided at a relatively high position, the water that has flowed into the mixing section 12 flows in the mixing section 12 so as to fall. A falling stream of water can also be used to further promote the mixing of the detergent and water.

Further, according to the washing machine 1, the detergent supply path 17 is provided with the automatic detergent injection unit 15 that automatically injects the detergent. According to this configuration, the detergent can be automatically added, and the burden on the user can be reduced compared to a washing machine in which the user manually adds the detergent. Further, the detergent automatic injection unit 15 is configured to measure and inject a predetermined amount of detergent by a metering pump 18 . Therefore, compared to a washing machine in which a user manually adds detergent, the amount of detergent added in one operation can be accurately adjusted.

(Second embodiment)
This embodiment relates to an example of controlling the supply of water and detergent into the cleaning tank 3 . As illustrated in FIG. 4, when the washing process is started, the control device 30 of the washing machine 1 first detects the weight of the clothes contained in the washing tub 3 (A1). Note that the weight detection process for detecting the weight of the clothes determines the weight of the clothes based on the variation in the current value of the motor when the drum in the washing tank 3 is rotated at a predetermined rotational speed for weight detection, for example. Well-known methods such as a method and a method of determining by a physical weight measuring device that measures the variation in the weight of the entire cleaning tank 3 including the rotating tank can be appropriately adopted.

After completing the weight detection process, control device 30 determines the amount of detergent to be added according to the detected weight of the clothes (A2). As a result, the amount of detergent injected by one detergent injection operation of the metering pump 18 is set.

Next, the controller 30 drives the metering pump 18 to automatically supply the detergent through the detergent supply path 17 (A3). As a result, a predetermined amount of detergent is introduced into the mixing section 12 forming part of the water supply path 10 . Then, the controller 30 opens the water supply valve 11 to start supplying water through the water supply path 10 (A4). As a result, water is supplied into the mixing section 12 forming part of the water supply path 10 . Water and detergent are mixed in the mixing section 12 and supplied into the washing tank 3 .

Then, the control device 30 closes the water supply valve 11 when the open state of the water supply valve 11, that is, the operation of supplying water and detergent into the cleaning tank 3 continues for a predetermined time (A5). As a result, the operation of supplying water and detergent into the cleaning tank 3 is stopped. The predetermined time for which the water supply valve 11 is kept open can be changed and set as appropriate.

When the water supply valve 11 is closed, that is, when the supply of water and detergent into the cleaning tank 3 is stopped for a predetermined period of time, the control device 30 repeats the steps A3 to A5 described above. The predetermined time for maintaining the water supply valve 11 in the closed state can be changed and set as appropriate. Also, the number of times the processing of steps A3 to A5 is repeated can be changed and set as appropriate.

According to the second embodiment, the washing machine 1 is configured to alternately supply water through the water supply path 10 and automatically supply detergent through the detergent supply path 17 by the metering pump 18 . According to this configuration, the water and the detergent are supplied alternately into the mixing section 12, and the mixing of the water and the detergent in the mixing section 12 can be further promoted.

(Third embodiment)
This embodiment also relates to an example of controlling the supply of water and detergent into the cleaning tank 3 . As exemplified in FIG. 5, the control device 30 of the washing machine 1 performs weight detection processing (A1) for the weight of the clothes in the washing tub 3, determination processing (A2) for the detergent input amount based on the detected weight, detergent When the automatic detergent supply process (A3) through the supply path 17 is executed, the process of opening the water supply valve 11 (A4) and the process of closing the water supply valve 11 (A5) are alternately repeated. As a result, water is intermittently supplied into the mixing section 12 after a predetermined amount of detergent has been introduced. The number of times the process (A4) for opening the water supply valve 11 and the process (A5) for closing the water supply valve 11 are repeated can be changed and set as appropriate.

According to the third embodiment, the washing machine 1 is configured to intermittently supply water through the water supply path 10 after the metering pump 18 automatically supplies detergent through the detergent supply path 17. did. According to this configuration, the detergent supplied into the mixing section 12 can be efficiently mixed with water using the flow of water supplied thereafter and supplied into the washing tank 3 . Further, by intermittently supplying water after the detergent is supplied into the mixing unit 12, the flow of water supplied into the mixing unit 12 can be changed. The efficiency of mixing with the detergent can be further enhanced. Further, the detergent supplied into the mixing section 12 can be efficiently flowed out to the cleaning tank 3 side by the water supplied thereafter.

(Fourth embodiment)
This embodiment is an embodiment relating to a configuration example within the mixing section 12 . As illustrated in FIGS. 6 and 7, the mixing section 12 includes a mixing promotion section 40 composed of a plurality of protrusions 40a. The plurality of protrusions 40 a are arranged in a plurality of rows on the bottom surface of the mixing section 12 . Moreover, the plurality of protrusions 40 a are provided on the bottom surface of the mixing section 12 at a portion that does not face the detergent supply path 17 . Therefore, no protrusion 40 a is provided on the bottom surface of the mixing section 12 at the portion facing the detergent supply path 17 . Also, in this case, the plurality of protrusions 40a are all provided at the same height. The water source side path 10A and the cleaning tank side path 10B are connected to the mixing section 12 at positions shifted in the horizontal direction of the mixing section 12 .

According to the fourth embodiment, the water supplied from the water source side path 10A into the mixing section 12 flows toward the cleaning tank side path 10B while hitting the plurality of protrusions 40a. Therefore, turbulence is likely to occur in the water flowing through the mixing section 12, and the mixing of the water and the detergent can be further promoted.

In addition, the mixing promotion part 40 may have a configuration in which a projection part 40 a is also provided at a portion of the bottom surface of the mixing part 12 facing the detergent supply path 17 . According to this configuration, the detergent supplied from the detergent supply path 17 can be divided by the protrusions 40a, and the mixing of the detergent and water in the mixing section 12 can be further promoted. Further, the mixing promotion section 40 may have a configuration in which a plurality of protrusions 40 a are arranged at random positions on the bottom surface of the mixing section 12 .

Moreover, the mixing promotion part 40 may be configured such that the plurality of projections 40a have different heights. In this case, in the mixing section 12, by lowering the height of the protrusion 40a on the upstream side, that is, on the water source side path 10A side, the water supplied from the water source side path 10A into the mixing section 12 bounces off the protrusion 40a. The flow of water in the mixing unit 12 is directed from the water source side path 10A on the upstream side to the cleaning tank side path 10B side on the downstream side. can be stabilized.

Further, the water source side path 10A and the cleaning tank side path 10B are connected to the mixing section 12 at positions shifted in the horizontal direction of the mixing section 12 . According to this configuration, the water supplied into the mixing section 12 flows in the mixing section 12 along a diagonal line from the upstream side toward the downstream side. The flow path in can be lengthened to further promote mixing of water and detergent.

(Fifth embodiment)
This embodiment is also an embodiment related to a configuration example inside the mixing section 12 . As exemplified in FIGS. 8 and 9, the mixing section 12 includes a mixing promotion section 50 composed of rotary blades 50a. In this case, the rotor 50a is provided at the center of the bottom surface of the mixing section 12. As shown in FIG. At least the central portion of the rotor blade 50 a is provided on the bottom surface of the mixing section 12 at a portion that does not face the detergent supply path 17 . Therefore, at least the central portion of the rotor blade 50a is not provided in the portion of the bottom surface of the mixing section 12 that faces the detergent supply path 17 . The rotor blade 50 a may be configured to be rotated by a drive source such as a motor, or may be configured to be rotated using the flow of water in the mixing section 12 .

According to the fifth embodiment, the water flowing in the mixer 12 from the water source side path 10A on the upstream side to the cleaning tank side path 10B side on the downstream side can be stirred by the rotor 50a, thereby disturbing the flow. be able to. This can further promote mixing of water and detergent.

Note that the mixing promotion section 50 may be provided at a portion other than the central portion of the bottom surface of the mixing section 12 . Further, the mixing promotion section 50 may be configured to include a plurality of rotor blades 50a in the mixing section 12, for example. In this case, the mixing efficiency of water and detergent can be further improved by appropriately adjusting the arrangement positions of the plurality of rotor blades 50a.

(Sixth embodiment)
This embodiment is also an embodiment related to a configuration example inside the mixing section 12 . As illustrated in FIGS. 10 and 11, the mixing section 12 includes a mixing promotion section 60 composed of a plurality of walls 60a. The plurality of wall portions 60a are arranged on the bottom surface of the mixing portion 12 so as to alternately enter from the water source side path 10A on the upstream side toward the washing tank side path 10B side on the downstream side. As a result, on the bottom surface of the mixing section 12, a meandering flow path, a so-called labyrinth-like flow path, continuing from the upstream side to the downstream side is formed by the plurality of wall portions 60a. Further, the most upstream wall portion 60 a among the plurality of wall portions 60 a is provided at a portion of the bottom surface of the mixing portion 12 facing the detergent supply path 17 . Moreover, the plurality of wall portions 60a are provided at different heights. In this case, among the plurality of wall portions 60a, the height of the wall portion 60a on the most upstream side is low, and the height of the wall portion 60a located on the downstream side is higher.

According to the sixth embodiment, the water supplied from the water source side path 10A into the mixing section 12 flows along the meandering flow path formed by the plurality of wall portions 60a toward the washing tank side path 10B. Therefore, the channel in the mixing section 12 can be lengthened, and the mixing of water and detergent can be further promoted in the process of flowing through such a channel. Further, in the mixing section 12, the height of the plurality of wall sections 60a decreases toward the upstream side. Therefore, it is possible to suppress the water supplied from the water source side path 10A into the mixing section 12 to bounce off the wall portion 60a and flow back to the water source side path 10A side, and the flow of water in the mixing section 12 can be suppressed. Stability can be achieved from the water source side path 10A, which is the upstream side, toward the cleaning tank side path 10B side, which is the downstream side.

Further, according to the sixth embodiment, the wall portion 60 a is provided on the bottom surface of the mixing portion 12 at the portion facing the detergent supply path 17 . According to this configuration, the detergent supplied from the detergent supply path 17 can be separated by the wall portion 60a, and the mixing of the detergent and water in the mixing section 12 can be further promoted. Note that the mixing promotion section 60 may have a configuration in which the wall section 60 a is not provided at the portion of the bottom surface of the mixing section 12 that faces the detergent supply path 17 . Further, the mixing promoting section 60 may be configured such that the plurality of wall sections 60a have the same height.

(Seventh embodiment)
This embodiment is an embodiment in which a predetermined function is imparted to the water supplied to the inside of the mixing section 12 and thus the inside of the washing tank 3 . As illustrated in FIG. 12 , the water supply section 4 further includes a microbubble generator 70 in the water supply path 10 . In this case, the microbubble generator 70 is provided downstream of the water supply valve 11 in the water source side path 10A forming part of the water supply path 10 .

The microbubble water generator 70 is a device for generating microbubble water by adding microbubbles to the water passing through it. Although detailed illustration is omitted, the micro-bubble water generator 70 has a channel having a constricted portion and projections. The water flowing through this flow path is throttled when passing through the throttle portion, and the flow velocity and pressure gradually increase, and the water collides with the protrusion in a state of high flow velocity and high pressure. Then, when the water with high flow velocity and high pressure collides with the protrusion and passes through the protrusion, the pressure of the water drops rapidly. Due to the cavitation effect caused by this rapid pressure drop, a large number of fine bubbles with a diameter of several tens of nanometers to several microns, eg, 50 microns or less in diameter, are generated in water at a number of, eg, 10 ⁶ or more/ml.

Fine bubbles generated in this manner are called microbubbles, nanobubbles, ultrafine bubbles, and the like. Here, microbubbles are generally classified as follows according to the particle size of the bubbles. For example, bubbles having a particle size of several μm to 50 μm, that is, micro-order bubbles are called microbubbles or fine bubbles. On the other hand, bubbles with a particle diameter of several hundred nm to several tens of nm or less, that is, nano-order bubbles are called nanobubbles or ultrafine bubbles.

When the particle size of the bubbles is several hundred nm to several tens of nm or less, they become smaller than the wavelength of light and cannot be visually recognized, and the liquid becomes transparent. Nano-order microbubbles have characteristics such as a larger total interfacial area, a lower floating speed, and a higher internal pressure than micro-order or larger bubbles. For example, bubbles with micro-order particle diameters rise rapidly in the liquid due to their buoyancy, burst on the surface of the liquid and disappear, so that the residence time in the liquid is relatively short. On the other hand, microbubbles with a nano-order particle size have a low buoyancy and thus stay in the liquid for a long time.

Water containing such fine air bubbles is excellent in surface activity, and contributes to improvement in washing performance of laundry, particularly in washing performance against greasy stains such as sebum stains. That is, the micro-bubble water generated by the micro-bubble water generator 70 has a function of improving cleaning performance due to the micro-bubbles.

In addition, the anionic (anion) surfactant, which is the main component of the detergent, and the microbubbles in the microbubble water each individually have the ability to remove stains. However, for example, when fine-bubble water is added to concentrated detergent water by dissolving the detergent in fine-bubble water, an attractive interaction between molecules called hydrophobic interaction causes the surfactant in the detergent to interact with the fine bubbles. The air bubbles are adsorbed, thereby loosening the aggregates or micelles of the surfactant and making it easier to disperse in water. As a result, the surfactant readily reacts with stains in a short period of time, improving the cleaning ability.

That is, by dissolving the detergent in the microbubble water to generate the washing liquid, the interaction between the surfactant in the detergent and the microbubbles in the microbubble water works, and as a result, the detergent is simply dissolved in the tap water. The washing ability can be remarkably improved compared to the simple washing liquid or the simple fine bubble water. In addition, since dirt is emulsified and easily dispersed in water, an effect of preventing redeposition of dirt on clothes can be expected.

According to the seventh embodiment, it is possible to supply the micro-bubble water having the effects described above into the mixing section 12 and mix the micro-bubble water and the detergent. Therefore, it is possible to mix the detergent with water while enhancing the dispersibility of the detergent, and supply the mixed liquid of water and detergent with higher cleaning performance into the cleaning tank 3 .
