Hereinafter, a plurality of embodiments according to a washing machine will be described with reference to the drawings. In each embodiment, substantially the same elements are denoted by the same reference numerals, and the description thereof is omitted.
(First embodiment)
The washing machine 10 illustrated in FIG. 1 is a so-called vertical type washing machine in which the rotation axis of the rotation tub is oriented in the vertical direction, and includes an outer box 11, a top cover 12, a water tub 13, a rotation tub 14, a pulsator 15, A motor 16 and a water supply mechanism 17 are provided. The outer box 11 constitutes an outer shell of the washing machine 10 and is configured as a rectangular box as a whole by, for example, a steel plate. The top cover 12 is made of, for example, a synthetic resin and is provided on the upper portion of the outer box 11.

The water tank 13 and the rotating tank 14 function as a washing tub and a dehydrating tub for storing laundry such as clothes to be cleaned. The water tank 13 is provided in the outer box 11. The water tank 13 and the rotating tank 14 are configured in a cylindrical shape with a bottom having an upper surface opened. The rotating tank 14 has a plurality of small holes 14a, and water passes between the rotating tank 14 and the water tank 13 through the small holes 14a. Further, a drain port (not shown) is formed at the bottom of the water tank 13. A drainage mechanism (not shown) is connected to the drainage port of the water tank 13. The drainage mechanism includes a drainage valve and the like in the middle of a drainage path extending from the drainage port of the water tank 13 to the outside of the machine.

The motor 16 is connected to the rotating tub 14 and the pulsator 15 via a clutch mechanism (not shown). The clutch mechanism selectively transmits the rotation of the motor 16 to the rotary tank 14 and the pulsator 15. The motor 16 and the clutch mechanism transmit the driving force of the motor 16 to the pulsator 15 in a state where the rotation of the rotating tub 14 is stopped during the washing process of washing the laundry in the rotating tub 14 and the rinsing process of the laundry. Thus, the pulsator 15 is directly rotated in the forward direction and the reverse direction at a low speed. Further, the motor 16 and the clutch mechanism transmit the driving force of the motor 16 to the rotating tub 14 during the dehydration process for dehydrating the laundry in the rotating tub 14 so that the rotating tub 14 and the pulsator 15 are unidirectional. Drive at high speed.

The water supply mechanism 17 is provided above the outer box 11 and inside the top cover 12. The water supply mechanism 17 includes a water injection case 19 in the middle of the water supply path 18. The water injection case 19 has a rectangular container shape, for example, and is disposed above the water tank 13. A washing treatment agent case (not shown) is accommodated in the water injection case 19 so that it can be taken in and out. The laundry treatment agent case is provided with a liquid detergent container for storing liquid detergent, a powder detergent container for storing powder detergent, a softener container for storing softener, and the like.

A water inlet 19 a is provided at the bottom of the water injection case 19. The water injection port 19a communicates the internal space of the water injection case 19 with the outside. The water that has flowed into the water injection case 19 dissolves various laundry treatment agents via the laundry treatment agent case, and is poured into the water tank 13 from the water injection port 19a. The water injection port 19a is provided in the upper part of the water tank 13 and the rotary tank 14, and is provided at a position that can be visually recognized by the user when the user uses the washing machine 10. The water injection port 19a may be configured separately from the water injection case 19. A piping member such as a hose may be interposed between the water injection case 19 and the water injection port 19a.

The proximal end portion of the water supply path 18 is connected to a water source (not shown) such as a water supply existing outside the outer box 11. On the other hand, the front end portion of the water supply path 18 is branched into a plurality of, in this case, a normal water supply path 18A and a fine bubble water supply path 18B. The tip of the normal water supply passage 18A and the tip of the fine bubble water supply passage 18B are connected to the water injection case 19, respectively.

The normal water supply passage 18A includes a water supply valve 18A1. The normal water supply path 18A does not include the micro-bubble water generator 20 described later. The normal water supply path 18A supplies water supplied from a water source (not shown) as it is into the water injection case 19 as normal water that does not contain fine bubbles. That is, the normal water supply path 18 </ b> A can be defined as a general water supply path provided in the washing machine for supplying washing water into the water tank 13.

On the other hand, the water supply path 18B for fine bubble water includes a water supply valve 18B1 and a fine bubble water generator 20. The fine bubble water generator 20 is an example of a fine bubble water generator that generates fine bubble water containing fine bubbles. Although detailed illustration is omitted, the fine bubble water generator 20 includes a flow path having a throttle part and a protrusion part. The water flowing through this flow path is squeezed when passing through the throttle portion, and the flow velocity and pressure gradually increase, and collides with the protrusion in a state where the flow velocity and pressure are high. And if the water which became high flow velocity and high pressure collides with a projection part and passes the said projection part, the pressure of the water will fall rapidly. Due to the cavitation effect caused by this rapid pressure drop, a large number of fine bubbles having a diameter of several tens nm to several μm, for example, a diameter of 50 μm or less, for example, 10 ⁶ or more / ml are generated in water.

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

When the bubble particle size is several hundred nm to several tens of nm or less, it becomes smaller than the wavelength of light and cannot be visually recognized, and the liquid becomes transparent. The nano-order fine bubbles have characteristics such as a large total interface area, a low levitation speed, and a large internal pressure, as compared with bubbles of the micro-order or higher. For example, bubbles having a particle size of the micro order rapidly rise in the liquid due to the buoyancy, and rupture and disappear on the liquid surface. Therefore, the residence time in the liquid is relatively short. On the other hand, microbubbles having a particle size of nano-order have a long residence time in a liquid because of their small buoyancy.

And such water containing fine bubbles is excellent in surface active action, and contributes to the improvement of washing performance of laundry, in particular, washing performance of oily dirt including sebum dirt. That is, the fine bubble water generated by the fine bubble water generator 20 has a function of improving the cleaning performance by the fine bubbles.

The water supply path for fine bubble water 18B causes the fine bubble water generator 20 to generate fine bubble water by adding fine bubbles to water supplied from a water source (not shown). The fine bubble water supply path 18 </ b> B supplies the generated fine bubble water into the water injection case 19. That is, the water supply path 18B for fine bubble water can be defined as a water supply path for supplying fine bubble water provided separately from a general water supply path in order to supply fine bubble water into the water tank 13.

2 is composed mainly of a microcomputer, for example, and is provided, for example, on the back surface of an operation panel (not shown) provided in the upper portion of the outer box 11. The control device 30 controls the overall operation of the washing machine 10 by executing a control program. Moreover, the control apparatus 30 implement | achieves the water supply control process part 31 virtually by software by running a control program. In addition, the water supply control process part 31 may be comprised with a hardware, and may be comprised with the combination of software and hardware.

The water supply control processing unit 31 is an example of a water supply control unit, and controls the supply of normal water into the water tank 13 by controlling the operation of the water supply valve 18A1, and also controls the operation of the water supply valve 18B1. The supply of fine bubble water into the water tank 13 is controlled. The water supply control processing unit 31 appropriately sets the time for supplying normal water into the water tank 13 and the time for supplying fine bubble water into the water tank 13 during the water supply operation in the washing process or the rinse process in various operation courses. By adjusting, the supply amount of fine bubble water with respect to the total water supply amount supplied into the water tank 13 can be changed. Further, the water supply control processing unit 31 may be configured to supply normal water into the water tank 13 first and then supply fine bubble water into the water tank 13 during the water supply operation. 13 may be configured such that fine bubble water is supplied into the water tank 13 and then normal water is supplied into the water tank 13, or normal water and fine bubble water may be supplied into the water tank 13 at the same time. Good.

As illustrated in FIG. 3, the water supply control processing unit 31 supplies fine bubble water into the water tank 13 in the initial stage during the water supply operation of the washing process or the rinsing process in various operation courses. Then, it is comprised so that control which supplies normal water in the water tank 13 is executable. Further, as illustrated in FIG. 4, the water supply control processing unit 31 supplies normal water into the water tank 13 in the first half of the initial stage during the water supply operation in the washing process or the rinse process in various operation courses. In the latter half, control for supplying fine bubble water into the water tank 13 is configured to be executable. The control example shown in FIG. 3 and the control example shown in FIG. 4 may be selected based on, for example, a selection operation by a user, or may be automatically performed by the control device 30 based on a control program. You may comprise.

In addition, the control device 30 is configured to be capable of executing a plurality of types of operation courses, and the water supply control processing unit 31 is adapted to each of the operation courses, and the microbubble water with respect to the total water supply amount supplied into the water tank 13 The control for changing the supply amount, in other words, the control for changing the concentration of fine bubbles contained in the water supplied into the water tank 13 is configured. In addition, the density | concentration of the fine bubble supplied in the water tank 13 is calculated | required by dividing the amount of fine bubble water supplied in the water tank 13 by the total amount of water containing the normal water supplied in the water tank 13, for example. It is done. Moreover, the density | concentration of the microbubble supplied in the water tank 13 changes the supply ratio of the water other than the microbubble water supplied in the water tank 13 and the microbubble water supplied in the water tank 13, for example, normal water. Can be adjusted. Moreover, the density | concentration of the fine bubble supplied in the water tank 13, in other words, generation amount can be changed also by adjusting the water pressure of the water which flows through the water supply path 18B for fine bubble water. The water pressure of the water flowing through the fine bubble water supply path 18B is controlled, for example, by adjusting the opening of the water supply valve 18B1, the water pressure of the external water source itself, the flow path diameter of the fine bubble water supply path 18B, and the like. be able to.

As illustrated in FIG. 5, in the present embodiment, the control device 30 is configured to be capable of executing at least a standard course, a multi-supply short course, a small supply long course, and a high cleaning course.
When the standard course is executed by the control device 30, the water supply control processing unit 31 sets the supply amount of fine bubble water with respect to the total water supply amount supplied into the water tank 13 to a standard level, for example, 50%, and the water tank 13. The supply time for supplying the fine bubble water is set to a standard level, for example, 7 minutes.

When the multi-supply short-time course is executed by the control device 30, the water supply control processing unit 31 sets the supply amount of fine bubble water with respect to the total water supply amount supplied into the water tank 13 to a multi-level higher than the standard level described above. In addition, the supply time for supplying the fine bubble water into the water tank 13 is set to a short level shorter than the standard level. That is, simply increasing the amount of fine bubble water supplied into the water tank 13 increases the supply time. Moreover, since the flow velocity of water also falls by the flow-path resistance in the throttle part of the fine bubble water generator 20, when the supply amount of fine bubble water is increased, the supply time tends to be long. Therefore, in this multi-supply short-time course, the amount of fine bubble water supplied into the water tank 13 is increased, and the stirring time of the pulsator 15 at the time of water supply is set shorter than the standard so that the overall requirement is reached. The course is shortened.

When the small supply long time course is executed by the control device 30, the water supply control processing unit 31 sets the supply amount of the fine bubble water with respect to the total water supply amount supplied into the water tank 13 to a small level lower than the above-described standard level. In addition, the supply time for supplying the fine bubble water into the water tank 13 is set to a long level longer than the standard level. By reducing the supply amount of the fine bubble water supplied into the water tank 13, the supply time can be shortened. Therefore, in this small supply long time course, the stirring time of the pulsator 15 at the time of water supply can be set longer than the standard according to reducing the supply amount of the fine bubble water supplied in the water tank 13.

When the high cleaning course is executed by the control device 30, the water supply control processing unit 31 is configured as high-concentration fine bubble water in which the concentration of fine bubble water contained in the fine bubble water is higher than the concentration of fine bubble water in the standard course. Supply into the water tank 13. Since the concentration of fine bubble water in the standard course is 50 percent, for example, in this high cleaning course, the water supply control processing unit 31 is at least a high concentration higher than the concentration in the standard course, for example, a high level of 100 percent. Concentrated fine bubble water is generated and supplied into the water tank 13. That is, the water supply control processing unit 31 executes water supply into the water tank 13 not using the normal water supply path 18A but using the fine bubble water supply path 18B. In addition, the supply time of the fine bubble water in this high washing course can be set suitably, for example, may be longer than the supply time in a standard course, may be short, and may be the same.

According to the present embodiment, in the washing machine 10 configured to be able to execute a plurality of types of driving courses having different driving contents, the control device 30 supplies the total amount of water supplied into the water tank 13 according to each driving course. The supply amount of fine bubble water is changed. Thereby, the supply amount of fine bubble water can be optimized in each operation course, and the function of fine bubble water can be exhibited effectively.

In this case, the control device 30 determines the concentration of fine bubbles supplied into the water tank 13 according to the operation course, in other words, fine bubble water supplied into the water tank 13 and water other than the fine bubble water, The supply ratio of normal water is changed. Here, the factor that has the most influence on the effect of improving the cleaning performance by the fine bubble water is the “concentration” of the fine bubbles contained in the water supplied into the water tank 13. Therefore, by paying attention to the “concentration” of the fine bubbles and appropriately changing the concentration according to the operation course, it is possible to exhibit the cleaning performance suitable for each operation course.

Further, the control device 30 increases the supply amount of the fine bubble water with respect to the total water supply amount supplied into the water tank 13 more than a predetermined amount, and the supply time for supplying the fine bubble water into the water tank 13 is shorter than the predetermined time. A multi-supply short-term course can be executed. According to this multi-supply short time course, a large amount of fine bubble water can be supplied into the water tank 13 in a short time, and the time required for supplying the fine bubble water can be shortened.

Further, the control device 30 reduces the supply amount of the fine bubble water with respect to the total water supply amount supplied into the water tank 13 below a predetermined amount, and the supply time for supplying the fine bubble water into the water tank 13 is longer than the predetermined time. It is possible to carry out a small supply long time course. According to this small supply long time course, although the time required for supplying the fine bubble water becomes long, the fine bubble water can be gradually supplied into the aquarium 13, and the fine bubble water is brought into contact with the laundry treatment agent carefully. Can be supplied.

Further, the control device 30 can execute a high cleaning course in which high-concentration fine bubble water in which the concentration of fine bubble water contained in the fine bubble water is higher than a predetermined concentration is supplied into the water tank 13. According to this high cleaning course, the laundry treatment agent can be dissolved and supplied into the water tank 13 with high-concentration fine bubble water. Therefore, the function of fine bubble water can be exhibited more effectively, and the cleaning performance can be further improved.

Further, the water supply control processing unit 31 sets the concentration of the fine bubble water supplied to the standard course to 100 percent, and the concentration of the fine bubble water in the other operation courses to a concentration lower than 100 percent, for example, 70 percent, 50 percent. You may set it.

Further, the water supply control processing unit 31 may set the concentration of the fine bubble water supplied to the short course to a concentration lower than the concentration of the fine bubble water in the other operation course. That is, the time required for the water supply operation can be further shortened by shortening the supply time of the fine bubble water and reducing the concentration of the supplied fine bubble water. In particular, when washing laundry using a liquid detergent, a sufficient washing effect can be expected even if the supply amount of fine bubble water is reduced compared to washing laundry using a powder detergent. Therefore, in the case of using a liquid detergent, it is possible to exhibit a sufficient cleaning effect while shortening the water supply operation by shortening the supply time of the fine bubble water and reducing the concentration of the supplied fine bubble water. it can.

Note that the control example illustrated in FIG. 5 is merely an example, and the water supply control processing unit 31 can appropriately set the supply amount and supply time of the fine bubble water in each operation course. That is, for example, the supply amount of fine bubble water in the multi-supply short-time course can be set to the standard level, and the supply amount of fine bubble water in the other operation courses can be greater than, less than, or the same as the standard level. In addition, the supply amount of fine bubble water in the low supply long-time course can be set to the standard level, and the supply amount of fine bubble water in the other operation courses can be larger, less than or equal to the standard level.

Also, the supply time of the fine bubble water in the multi-supply short time course can be set to the standard level, and the supply time of the fine bubble water in the other operation courses can be made longer, shorter or the same as the standard level. Moreover, the supply time of the fine bubble water in the low supply long time course can be set to the standard level, and the supply time of the fine bubble water in the other operation courses can be made longer, shorter or the same as the standard level.

(Second Embodiment)
As illustrated in FIG. 6, in the present embodiment, the water supply control processing unit 31 changes the supply amount of the fine bubble water with respect to the total water supply amount supplied into the water tank 13 according to the operation process, not the operation course. . That is, for example, the standard course includes a washing process, a shower rinsing process, and a rinsing process. The washing process is a process in which water is supplied into the water tank 13 up to a predetermined water level for the washing process and the pulsator 15 is rotated to stir and wash the laundry in the rotating tank 14. The shower rinsing process is a process of rinsing the laundry in the rotating tub 14 while circulating the water in the water tub 13 through a circulation path (not shown) and returning the water from the upper part of the water tub 13 to the rotating tub 14 in a shower shape. The rinsing process is a process of supplying water to the water tank 13 up to a predetermined water level for the rinsing process and rotating the pulsator 15 to agitate the laundry in the rotating tub 14 for rinsing. In addition, the water level in the water tank 13 in the shower rinsing process can be set at a lower water level than the water level in the water tank 13 in the rinsing process.

In the washing process, the water supply control processing unit 31 sets the supply amount of fine bubble water to the standard level with respect to the total water supply amount supplied into the water tank 13. In the shower rinsing process, the water supply control processing unit 31 sets the supply amount of fine bubble water with respect to the total water supply amount supplied into the water tank 13 to a lower level than the standard level. Therefore, in the rinsing process, the water supply control processing unit 31 sets the supply amount of fine bubble water with respect to the total water supply amount supplied into the water tank 13 to a multilevel higher than the standard level.

According to the present embodiment, the control device 30 changes the supply amount of fine bubble water with respect to the total water supply amount supplied into the water tank 13 according to the operation stroke. Thereby, the supply amount of the fine bubble water can be optimized in each operation stroke, and the function of the fine bubble water can be effectively exhibited.

Note that the control example illustrated in FIG. 6 is merely an example, and the water supply control processing unit 31 can appropriately change and set the supply amount of fine bubble water in each operation process. That is, for example, the supply amount of the fine bubble water in the shower rinsing process can be set to the standard level, and the supply amount of the fine bubble water in the other operation processes can be made larger, smaller or the same as the standard level. In addition, the supply amount of the fine bubble water in the rinsing process can be set to the standard level, and the supply amount of the fine bubble water in the other operation processes can be made larger, smaller or the same as the standard level. Moreover, the water supply control processing part 31 can also change and set the supply time of the fine bubble water in each driving | operation process suitably similarly to the supply amount of the fine bubble water.

(Third embodiment)
As illustrated in FIG. 7, the control device 30 further realizes the temperature detection processing unit 32 virtually by software by executing a control program. The temperature detection processing unit 32 may be configured by hardware, or may be configured by a combination of software and hardware. The temperature detection processing unit 32 is an example of a temperature detection unit. In this case, the temperature detection processing unit 32 is configured to detect the temperature of water in the water tank 13. That is, a temperature detection sensor (not shown) is provided in the water tank 13, and the temperature detection processing unit 32 detects the temperature of the water in the water tank 13 through this temperature detection sensor.

And the water supply control processing part 31 adjusts the supply amount of the fine bubble water with respect to the total water supply amount supplied in the water tank 13 according to the temperature detected by the temperature detection processing part 32. That is, in the control example illustrated in FIG. 8, the water supply control processing unit 31 increases the supply amount of fine bubble water relative to the total water supply amount supplied into the water tank 13 as the temperature detected by the temperature detection processing unit 32 is lower. To do. In the control example illustrated in FIG. 9, the water supply control processing unit 31 decreases the supply amount of fine bubble water relative to the total water supply amount supplied into the water tank 13 as the temperature detected by the temperature detection processing unit 32 is lower. To do.

According to the present embodiment, the control device 30 adjusts the supply amount of fine bubble water relative to the total water supply amount supplied into the water tank 13 according to the temperature of the water in the water tank 13 detected by the temperature detection processing unit 32. To do. Thereby, according to the temperature of the water in the water tank 13, the supply amount of fine bubble water can be optimized, and the function of fine bubble water can be exhibited effectively.

In general, the cleaning performance is greatly influenced by the feed water temperature, but even if the feed water temperature is relatively low, the effect of improving the cleaning performance by about 10 to 20% due to the presence of fine bubble water is recognized. . Therefore, even if the water supply temperature is relatively low, at least for oily and dirt such as sebum dirt, cleaning performance equivalent to that when the water supply temperature is high can be expected.

In addition, you may comprise the temperature detection process part 32 so that the temperature outside the machine of the washing machine 10 may be detected. That is, for example, the washing machine 10 may include a temperature detection sensor on the outer surface of the outer box 11, and the temperature detection processing unit 32 may be configured to detect the temperature of the outside air of the washing machine 10 via this temperature detection sensor. Then, the water supply control processing unit 31 adjusts the supply amount of fine bubble water with respect to the total water supply amount supplied into the water tank 13 according to the temperature of the outside air detected by the temperature detection processing unit 32. According to this configuration, the supply amount of fine bubble water can be optimized according to the temperature of the outside air, and the function of fine bubble water can be effectively exhibited.
