Description

Press washer, washing machine and washing equipment

The present disclosure relates to a washing machine, a washing machine, and a washing apparatus for washing laundry such as clothes.

Conventional washing machines include a vertical washing machine that stirs and wash laundry such as clothes in a rotating tub, and a drum that lifts the laundry in the rotating direction in the rotating tub and drops it from above to wash it. There is a washing machine. Both washing machines wash laundry by applying mechanical force to the laundry in addition to the chemical power of the detergent. The dehydration of the washed laundry is generally centrifugal dehydration in which water is separated from the laundry by centrifugal force generated by high-speed rotation of the rotating tub.

These washing machines that wash by applying a strong mechanical force to the laundry are those that are prone to fabric damage, those that are prone to being out of shape when the laundry is tangled and pulled, and those that are prone to deterioration in texture, etc. It is not suitable for washing delicate clothes such as clothes (generally hand-washed, for example, knitted wool and woolen fabrics such as sweaters and cardigans, and scarves made of fine fibers). Also, dehydration after washing is not appropriate for such laundry with prolonged centrifugal dehydration.

Then, the washing machine provided with the washing apparatus which wash | cleans it by pushing repeatedly with a hand is considered so that it can wash without damaging the clothes etc. of such a delicate material (for example, patent document 1). reference).

As shown in FIG. 13, a conventional washing machine 100 described in Patent Document 1 includes a washing unit 101 having a washing tub (not shown) in which a water flow generating pulsator (not shown) is provided on the inner bottom. And a dehydrating part 102 having a dewatering tank (not shown) having a centrifugal dewatering rotary rod (not shown) provided therein. A small tank 103 is disposed adjacent to the rear of the dehydrating unit 102. The small tank 103 is formed in a shallow flat container shape.

When washing laundry such as a sweater, water is supplied to the small tub 103 to the extent that the laundry that is folded and set in the small tub 103 is immersed, and the washing operation is started after the detergent is introduced. When the washing operation is started, the washing action member 104 alternately applies a pressing action and a relaxation action to the laundry. Thereby, absorption and discharge | release of the detergent liquid to a laundry are repeated, stain | pollution | contamination is discharge | released in a liquid, and it can wash without damaging a sweater etc.

However, the conventional configuration described in Patent Document 1 has a problem that it is not easy to use when washing laundry such as a sweater in the small tub 103 and a good cleaning effect cannot be obtained.

That is, the small tub 103 in which the washing is performed is disposed behind the dewatering unit 102 disposed adjacent to the washing unit 101. For this reason, the size of the small tank 103 is restricted, and the area of the small tank 103 cannot be sufficiently secured. For this reason, the object to be cleaned is folded into a size that can be set in the small tub 103 and is washed in that state, so that the object to be cleaned tends to wrinkle at the end of the washing. Moreover, since the user needs to work with his arms extended to the small tub 103 disposed at a position away from the front surface of the washing machine, the user experience is poor.

A water level switch 33 is provided.

The bottom 14a of the washing tank 14 is provided with a drain hole 34 for discharging the washing water used in the washing process or the like. The drain hole 34 communicates with a drain passage 36 provided with a drain valve 35. By opening and closing the drain valve 35, the drain and supply of the cleaning water in the cleaning tank 14 are stopped.

Further, the water tank unit 11 is provided with an overflow channel 37 for draining the cleaning water in the cleaning tank 14 to the outside when the water level in the cleaning tank 14 exceeds a predetermined level (see FIG. 5 and the like). ). The overflow path 37 has an overflow hole 37 a in the upper part of the cleaning tank 14, and is connected to the drain path 36 on the downstream side of the drain valve 35.

In the overflow channel 37, a check valve (not shown) is provided. The check valve is configured to open the overflow path 37 in the discharge direction and seal the overflow path 37 in the inflow direction. In the washing process and the rinsing process, the check valve allows the washing water that has flowed out of the overflow hole 37a to pass through and is discharged to the outside. Further, the dehydration process is configured to prevent the outside air from flowing into the cleaning tank 14 when the air in the cleaning tank 14 is sucked by the pump 20 described later.

A suction port 38 is provided at the bottom 14 a of the cleaning tank 14. The suction port 38 is provided at a position covered with the cleaning object 16 when the cleaning object 16 is set in the cleaning tank 14. For example, in the present embodiment, the suction port 38 is provided substantially at the center of the bottom portion 14a. A suction path 39 is provided in communication with the suction port 38. The suction path 39 connects the cleaning tank 14 and the suction port 20 b of the pump 20 via the suction port 38. The pump 20 sucks cleaning water from the air in the cleaning tank 14 and the object to be cleaned 16 through the suction path 39. As described above, at this time, the pump 20 functions as a suction unit.

When the cleaning water is sucked from the cleaning object 16 by the pump 20, the air in the cleaning tank 14 is also sucked. At this time, the water tank section 11 is provided with an outside air introduction section 40 that introduces outside air into the cleaning tank 14 from the outside of the cleaning tank 14 at this time. The outside air introduction unit 40 only needs to be provided with an opening above the level of the cleaning water stored in the cleaning tank 14. For example, in the present embodiment, the outside air introduction unit 40 is provided in the water level detection unit 30 that communicates with the inside of the cleaning tank 14.

The outside air introduction section 40 is provided with an air volume adjustment valve 41 which is an air volume adjustment section capable of adjusting the air volume introduced. The air volume adjusting valve 41 has a narrow air passage area portion in the flow path like a needle valve, for example, and is configured to be able to adjust the air volume sucked by the pump 20. The outside air to be sucked in may be introduced directly from the outside of the washing machine S1, or may be introduced through the internal space of the washing machine S1.

The suction path 39 is provided with a gas-liquid separation unit 42 that separates the air in the cleaning tank 14 and the cleaning water sucked from the object 16 to be cleaned and stores the sucked cleaning water. The gas-liquid separation unit 42 is configured by a pressure vessel. Further, the gas-liquid separator 42 includes a secondary side communication port 43 that communicates with the suction path 39 and a primary side communication port 44 that communicates with the suction port 20 b of the pump 20. A suction path opening / closing part 39 a for opening and closing the suction path 39 is provided between the primary side communication port 44 of the gas-liquid separation unit 42 and the suction port 20 b of the pump 20.

A barrier 45 is provided between the primary side communication port 44 and the secondary side communication port 43. The barrier 45 is formed so as to protrude downward from the top surface of the gas-liquid separator 42. The barrier 45 prevents the cleaning water sucked into the gas-liquid separator 42 from the secondary side communication port 43 from entering the primary side communication port 44.

A dewatering drain 46 is provided at the bottom of the gas-liquid separator 42. The dewatering drain port 46 communicates with a dewatering drain path 48 having a dewatering drain valve 47 that can be opened and closed. An overflow detection unit 49 is provided at a predetermined height of the inner wall of the gas-liquid separation unit 42. The overflow detection unit 49 is constituted by, for example, a pair of electrodes and the like, and detects that the washing water accumulated in the gas-liquid separation unit 42 has reached a predetermined amount. When the overflow detection unit 49 detects the washing water, the dewatering drain valve 47 is opened and the washing water is drained. The overflow detection unit 49 is provided so that a certain space exists between the lower end of the barrier 45 and the water surface when the washing water is detected.

As shown in FIG. 5 and the like, the control unit 50 is disposed, for example, on the side surface inside the lid body 12. An operation display unit 51 is provided on the upper surface of the control unit 50. The control unit 50 controls the washing process, the rinsing process, and the dehydrating process so that the washing operation is executed, so that the pump 20, the opening / closing unit 24, the water supply valve 28, the drain valve 35, the first switching unit 22a, the second switching unit. The switching unit 22b, the suction path opening / closing unit 39a, the air volume adjustment valve 41, the dewatering drain valve 47, and the like are controlled.

The operation and action of the press washing machine S1 configured as described above will be described below.

The user grasps the handle 12b and pulls out the water tank 11 and the lid 12 stored in the housing 3 (see FIGS. 1 and 2). And in the operation display part 51 (refer FIG. 5) provided in the upper surface front part of the cover body 12, selection of a driving course, the time of each process, etc. are input. The control unit 50 performs a washing, rinsing, and dehydration process based on the setting content input by the operation display unit 51. The user can arbitrarily select such as performing only the washing step or only the dehydration step. The setting operation in the operation display unit 51 may be performed after an object 16 to be described later is set in the cleaning tank 14.

After the user operates the handle 12b to unlock, the user opens the lid 12 by rotating it in the direction of arrow R to the position indicated by the broken line in FIG. And the to-be-cleaned object 16 is arranged in the bottom part 14a of the washing tank 14, and is set. Depending on the size of the object 16 to be cleaned, the object 16 to be cleaned may be folded and set. When the set of the cleaning object 16 is completed and the lid 12 is closed and locked, the control unit 50 starts operation according to the operation course set by the operation display unit 51.

In the washing process of the driving course, the controller 50 first performs a water supply operation. When the control unit 50 opens the water supply valve 28, tap water and detergent are supplied as cleaning water from the water supply path 27 into the cleaning tank 14. At this time, the air volume adjusting valve 41 is opened, and the drain valve 35, the suction path opening / closing part 39a and the dewatering drain valve 47 are closed. The supplied cleaning water gradually permeates the object 16 to be cleaned and is contained between the fibers of the object 16 to be cleaned. When the cleaning water is supplied to the inside of the cleaning tank 14 up to a predetermined water level and the water level switch 33 of the water level detection unit 30 detects that the cleaning water has reached the predetermined water level, the control unit 50 opens the water supply valve 28. Close.

When the supply of water is finished, the control unit 50 closes the opening / closing unit 24 and the air volume adjustment valve 41 so that only the discharge port 20a and the pressing unit 19a communicate with the first switching unit 22a via the first path 21a. (See FIG. 5). At the same time, the control unit 50 switches the second switching unit 22b so that only the suction port 20b and the pressing unit 19b communicate with each other via the fourth path 21d.

Next, the control unit 50 drives the pump 20 for a predetermined time or until the pressing unit 19a reaches a predetermined pressure. Thereby, the air in the pressing part 19b is sucked through the fourth path 21d, and the air is supplied into the pressing part 19a through the first path 21a. Then, as shown in FIG. 8A, the pressing portion 19b contracts (arrow B1), and the pressing portion 19a expands (arrow A1).

Specifically, the expansion / contraction part 19d of the pressing part 19a extends, and the pressing part 19a extends toward the object to be cleaned 16 in the direction of the arrow A1. Thereby, as for the to-be-cleaned object 16 below the press part 19a, the part pressed by the press surface 19c is compressed, and thickness becomes thin. As the object to be cleaned 16 is compressed and its volume changes, part of the cleaning water contained in the object to be cleaned 16 is pushed out of the object to be cleaned 16. As a result, a water flow is generated inside the object 16 to be cleaned, and the dirt adhering to the object 16 is removed away from the fibers by the water flow.

Further, a part of the cleaning water contained in the object to be cleaned 16 is inside the object to be cleaned 16 from below the pressing part 19a to below the pressing part 19b, that is, in the direction indicated by the arrow C1 in FIG. 8A. Move to. The washing water moving in this way pushes up the pressing surface 19c of the pressing portion 19b while expanding the object 16 to be cleaned below the pressing portion 19b.

Next, the control unit 50 keeps the opening / closing unit 24 and the air volume adjustment valve 41 closed so that only the discharge port 20a and the pressing unit 19b communicate with the first switching unit 22a via the second path 21b. Switch to. At the same time, the control unit 50 switches the second switching unit 22b through the third path 21c so that only the suction port 20b and the pressing unit 19a communicate with each other.

Next, the control unit 50 drives the pump 20 for a predetermined time or until the pressing unit 19b reaches a predetermined pressure. Thereby, the air in the pressing part 19a is sucked through the third path 21c, and the air is supplied into the pressing part 19b through the second path 21b. As shown in FIG. 8B, the pressing portion 19a contracts (arrow A2), and the pressing portion 19b expands (arrow B2).

Specifically, the expansion / contraction part 19d of the pressing part 19b extends, and the pressing part 19b extends in the direction of the arrow B2 toward the object 16 to be cleaned. Thereby, as for the to-be-cleaned object 16 below the press part 19b, the part pressed by the press surface 19c is compressed, and thickness becomes thin. As the object to be cleaned 16 is compressed and its volume changes, part of the cleaning water contained in the object to be cleaned 16 is pushed out of the object to be cleaned 16. As a result, a water flow is generated inside the object 16 to be cleaned, and the dirt adhering to the object 16 is removed away from the fibers by the water flow.

Further, a part of the cleaning water contained in the object to be cleaned 16 is inside the object to be cleaned 16 from below the pressing part 19b to below the pressing part 19a, that is, in the direction indicated by the arrow C2 in FIG. 8B. Move to. Then, the cleaning water moving in this way pushes the pressing surface 19c of the pressing portion 19a upward while expanding the object 16 to be cleaned below the pressing portion 19a.

Thus, in the washing step, the pressing portions 19a and the pressing portions 19b are configured to expand and contract alternately at different timings. For example, pressurization 1 second due to expansion of the press part 19a and decompression 1 second due to contraction of the press part 19b are repeated for a predetermined time (for example, 10 minutes). As a result, the object 16 to be cleaned is pushed and washed as if it were hand-washed, and the cleaning effect is exhibited.

That is, dirt can be removed by generating a multi-directional water flow inside the object 16 without mechanical force acting on the object 16 to be cleaned such as stirring and tapping. The press washer S1 may be configured such that the expansion and contraction of the pressing portion 19a and the pressing portion 19b are alternately performed at a predetermined pressure as well as alternately at a predetermined time as described above.

When a course for consistently executing from the washing process to the dewatering process is set, the control unit 50 sequentially executes the rinsing process and the dewatering process following the washing process.

In the rinsing process, for example, a rinsing operation is performed after the draining operation and the intermediate dehydrating operation. In the draining operation, the drain valve 35 is opened, and the cleaning water in the cleaning tank 14 is drained from the drain hole 34 to the outside through the drain path 36. At this time, the control unit 50 opens the air volume adjustment valve 41 to allow the cleaning tank 14 to communicate with the outside air, promotes air replacement, and smoothly discharges the cleaning water.

Since the intermediate dehydration operation is the same as the final dehydration operation described later, detailed description is omitted here. Note that the operation time of the intermediate dehydration operation is shorter than the final dehydration operation, for example, for 1 minute.

Therefore, in the rinse operation, the water supply valve 28 is opened by the control unit 50 and a predetermined amount of cleaning water is supplied into the cleaning tank 14. Thereafter, similarly to the washing step, the pump 20 is driven by the control unit 50, and the expansion and contraction of the pressing portions 19a and 19b are alternately repeated to dilute the detergent concentration of the washing water inside the article 16 to be cleaned. . The rinsing process is repeated a plurality of times (for example, twice).

Control part 50 performs a dehydration process after performing a rinse process. In the dewatering step, a draining operation and a final dewatering operation are performed.

First, the control unit 50 controls the drainage operation. The drain valve 35 is opened by the control unit 50, and the cleaning water in the cleaning tank 14 is drained from the drain hole 34 to the outside through the drain path 36. At this time, the air volume adjusting valve 41 is opened, the inside of the cleaning tank 14 is communicated with the outside, and the cleaning water is discharged smoothly. At this time, the air volume adjustment valve 41 is open, all the opening / closing parts 24 are closed, and the dewatering drain valve 47 is closed.

The control unit 50 controls the final dehydration operation after the drainage operation is completed. With the drain valve 35 closed, the control unit 50 opens the opening / closing unit 24 and the suction path opening / closing unit 39a, and sets the air volume adjustment valve 41 to a predetermined opening. Further, the control unit 50 presses the first switching unit 22a with the discharge port 20a through the first path 21a so that the discharge port 20a communicates with the pressing unit 19a and through the second path 21b. It switches so that the part 19b may communicate.

That is, the control unit 50 switches the first switching unit 22a so that all the pressing units 19 (19a, 19b) communicate with the discharge port 20a and air is supplied. Thereby, the press part 19 communicates with outside air, and the inside becomes atmospheric pressure. Further, the control unit 50 closes the second switching unit 22b so that the communication between the suction port 20b and all the pressing units 19 (19a, 19b) is blocked.

Next, the control unit 50 drives the pump 20. The pump 20 sucks the air in the cleaning tank 14 and the cleaning water inside the article 16 to be cleaned through the suction path 38 through the suction path 39. As shown by an arrow C3 in FIG. 9, the suctioned cleaning water flows out from the suction port 38 of the cleaning tank 14 to the suction path 39, moves to the gas-liquid separation unit 42, and is stored.

The sucked air in the cleaning tank 14 is supplied to the pressing portions 19a and 19b through the first and second paths 21a and 21b via the gas-liquid separator 42 and the pump 20. Accordingly, as shown in FIG. 9, the pressing portion 19a expands (arrow A3) and the pressing portion 19b expands (arrow B3).

When the air in the cleaning tank 14 is sucked, the outside air is introduced into the cleaning tank 14 from the outside air introduction unit 40. However, if the air volume adjusting valve 41 is throttled, sufficient outside air cannot be sucked, and the inside of the cleaning tank 14 is depressurized to become a lower pressure than the outside air. At this time, the supply of air from the pump 20 is small. For this reason, due to the pressure difference between the outside air and the inside of the cleaning tank 14, the outside air flows into the inside of the pressing part 19 from the opened opening / closing part 24, the pressing part 19 expands, and the object to be cleaned 16 is pressed. With such a configuration and action of the pressing portion 19, the pressing surface 19 c can be pressed against the object to be cleaned 16, and the cleaning water contained in the object to be cleaned 16 can be forced out. .

Also, the outside air that has flowed into the washing tank 14 from the outside air introduction unit 40 pushes out the washing water remaining between the fibers of the article 16 to be washed and moves it to the suction port 38. The washing water carried to the suction port 38 is carried from the suction port 38 through the suction path 39 to the gas-liquid separation unit 42 and is effectively dehydrated from the object 16 to be cleaned.

In this manner, the pressing portion 19 is expanded by the pump 20 so that the pressing surface 19c of the pressing portion 19 is brought into close contact with the object to be cleaned 16 and can be pressed uniformly. Introduced, a predetermined dewatering performance can be obtained.

The controller 50 sucks the cleaning water together with the outside air introduced into the cleaning tank 14 by the pump 20, stops the driving of the pump 20 after a predetermined time (for example, 4 minutes), and ends the dehydration process. .

During the dehydration process, when the washing water flows into the gas-liquid separation unit 42 exceeding the set amount, the control unit 50 detects this with the overflow detection unit 49 and stops the driving of the pump 20 to close the dewatering drainage that has been closed. The valve 47 is opened to drain the washing water from the drainage part 7a.

In the present embodiment, the press washer S1 is configured such that in the dehydration process, the air sucked together with the cleaning water from the inside of the cleaning tank 14 is supplied to the pressing unit 19 via the pump 20 and moves. Although comprised, you may be comprised so that it may discharge | emit outside, without moving to the press part 19. FIG.

Further, in the present embodiment, in the washing machine S1, the first switching unit 22a is provided at the branching portion of the pressurizing path 21, and the second switching unit 22b is provided at the branching portion of the decompression path 23. However, it is not limited to this configuration. For example, the press washing machine S1 may be configured by providing a pressurizing path and a depressurizing path for each of the plurality of pressing portions, and by providing an on-off valve that opens and closes each path.

In the present embodiment, in the dehydration process, the opening / closing part 24 is opened, the inside of the pressing part 19 is opened to the atmosphere, and the pressure difference between the inside of the pressing part 19 and the inside of the cleaning tank 14 is used. Although the configuration in which the object to be cleaned 16 is pressed is illustrated, the opening / closing part 24 may be closed and the pump 20 may be driven. According to such a configuration, air is supplied to the pressing portion 19 via the outside air introduction portion 40, and the article 16 to be cleaned is pressed in a state where the inside of the pressing portion 19 has increased to a predetermined pressure. Therefore, with such a configuration, the object to be cleaned 16 is more strongly dehydrated than when the atmospheric pressure is released. However, in this case, since the pressure difference between the inside of the pressing portion 19 and the inside of the cleaning tank 14 becomes large, it is desirable to strengthen the structure of the pressing portion 19 and consider the setting of a predetermined pressure. Furthermore, it is desirable to set the pressure, the time of each process, etc. in consideration of the influence on delicate clothing.

In the present embodiment, an example is shown in which the fluid that is supplied to the inside of the pressing portion 19 and expands the pressing portion 19 is air. However, the present invention is not limited to this, and other gases or liquids may be used. In the case of gas, as in the present embodiment, ambient air may be sucked with a pump or the like, and there are few restrictions when exhausting, which is convenient. In the case of a liquid, water, an aqueous solution or oil can be used. In the case of liquid, it is desirable that the washing machine S1 has a storage part for storing the liquid. Since the liquid has a higher density than air and is not as elastic as a gas, the pressing portion 19 can be reliably expanded.

The press-washing machine S1 of the present disclosure is not limited to the configuration of the present embodiment as long as it has a configuration that presses and cleans the article 16 to be cleaned.

With such a configuration, it is possible to generate a multi-directional water flow inside the object to be cleaned 16 without stirring the object to be cleaned 16, and it is possible to enhance the cleaning effect by suppressing fabric damage and shape loss.

Moreover, in the washing machine S1 of the present embodiment, the pump 20 may be configured to perform suction dehydration by sucking the air in the cleaning tank 14 and sucking the cleaning water from the object 16 to be cleaned. With such a configuration, the cleaning water can be effectively sucked and dehydrated from the object 16 to be cleaned by the pump 20, and can be effectively dehydrated without damaging the object 16 to be cleaned. Further, the press machine S1 of the present embodiment may be configured such that the dehydration operation is performed continuously after the press washing operation. With such a configuration, it is not necessary to move the object to be cleaned 16 that has been washed by observing the progress of the press-washing operation, and the vicinity of the object to be wetted by the movement of the wet object to be cleaned 16 does not need to be transferred.

Moreover, the press machine S1 of the present embodiment may include the housing 3 in which the cleaning tank 14 is accommodated. In this case, the cleaning tank 14 may be configured to be drawable from the housing 3.
