Description

[Detailed Description of the Invention] B) Industry - Field of Application of J2 The present invention relates to a washing machine with a water storage tank equipped with a washing tank and a water storage tank for storing liquid in the washing tank for reuse. Regarding.

(B) Prior Art In a conventional washing machine with a water storage tank, when the liquid in the washing tank is sent to the water storage tank and stored, the water level detection means of the washing tank detects that the water in the washing tank has run out. Water supply was to be terminated at that point or after a certain period of time.

With such devices, the liquid in the washing tub can be completely transferred to the water storage tank, but a large amount of liquid still remains in the clothes, and this liquid cannot be transferred and reused.

(c) Purpose of the Invention The object of the present invention is to provide a washing machine with a water storage tank that can transfer liquid contained in clothes to a water storage tank and reuse as much liquid as possible.

(D) Structure of the Invention The present invention provides a connecting waterway that connects a washing tub and a water storage tank, a connecting valve provided in this waterway that opens and closes the waterway, and a pump that transfers liquid from the washing tub to the water storage tank. and a water level detection means for detecting the water level in the washing tub, and has a water level detection means for detecting the water level in the washing tub.
- During the liquid transfer process, after the water level detection means detects that the liquid in the washing tub has run out, the connecting valve is opened for a predetermined period of time, and the pump is driven, and after this predetermined period of time, the pump is driven. After the connecting valve is once closed and the pump is stopped, the connecting valve is opened again for a certain period of time and the permanent tab is driven.

With this configuration, while the pump is temporarily stopped and the connecting valve is closed, the liquid contained in the clothes will seep out.
When the pump is driven again and the connecting valve is opened, this seeping liquid is stored in a water tank, so that as much liquid as possible can be reused.

(P) Examples Examples of the present invention will be described below with reference to the drawings. Figure (1) shows the main structural parts of a washing machine with a water storage tank according to the present invention. ) is provided with a washing tub (3) that also serves as a dehydration tub.

Therefore, when the connecting valve (17) and the drain valve (10) are opened at the same time, the liquid in the water storage tank (15) is also drained via the connecting waterway (16), the drain valve (lO), and the drain channel (11).

When the connecting valve (17) is open and the drain valve (10) is closed, the washing tank (3) and the water tank (15) are communicated through the connecting waterway (16), and the pump (18) is rotated in the forward direction. As a result, the water in the washing tub (3) moves to the water storage tank (15) (hereinafter referred to as liquid movement), and by rotating the pump (18) in the opposite direction, the water is stored! The water in (15) moves to the washing tub (3) (hereinafter referred to as return of the liquid). (20)
is a float switch that detects the presence or absence of water in the water tank (15). When the float switch (20) is closed, there is no water in the water tank (15) and the float switch (
20) is open, there is water in the water tank (15).

It is placed a little apart from ~ (32).

(34) is a reuse selector switch, and this switch is used to select between reuse of stone phosphorus water, reuse of rinse water, no reuse, and drainage (water tank).

Here, reusing soap water means, as is clear from the process diagram in Figure 4, that after the washing process is completed, the washing liquid is transferred to the water tank (15) for reuse. What to store, rinsing water reuse means performing the above-mentioned 1-liquid transfer after the second rinsing process and storing the rinsing water in the water tank (15), and not reusing means rinsing water. tank 3
) drains all the water in the tank without transferring it to the water tank, and (water tank) drainage means opening the drain valve (10) and connecting valve (17) and draining the washing tank (3) to Water supply valve (
35) to open the valve. ○ in the process diagram in Figure 4
A mark indicates that the process is executed, and a value of 0 indicates a process that is executed only in the case of a careful course.

(41) is a drive circuit for rotating the pump (18) in the reverse direction.
) is opened when the drain is opened, and also serves as a vibration detection switch during dewatering, and in this embodiment is also used to cancel drainage abnormalities. (43) is a buzzer.

The operation of this embodiment will be explained according to the flowcharts shown in FIGS. (5) to (14). Figures (5) to (7) are flowcharts showing the general outline of the software of this embodiment. Since the routine is shown in the form of a subroutine in FIG. (14), FIGS. (8) to (14) will be explained first.

Figure (8) shows a flowchart of the above-mentioned 1-liquid return,
To restore the liquid, the microcomputer (23) first determines whether there is water in the washing tub (3) based on the open/closed state of the liquid level switch (25). If there is water in the FC washing tank (3), proceed to the next process without recovering the liquid, and if there is no water in the FC washing tank (3), the microcomputer checks whether there is an abnormality in the pump (18). Judgment is made based on the stored contents in (23), and if the pump abnormality has occurred, the water supply valve (35) is opened until the liquid level switch (25) is closed to supply water to the washing tub (3).

Here, the occurrence of abnormality in the pump (18) means that the pump (18)
Specifically, in this embodiment, when the pump (18) is not operating normally due to foreign matter being clogged in the Even if the operation is performed for more than 3 minutes, the liquid level switch (25) that is the water level detection means for the washing tub (3) or the float switch (2) that is the water level detection means for the water storage tank (15) is not activated.
This refers to a case where there is no change in at least -B of 0). In such a case, the microcomputer (23) determines that there is a problem with the pump, stores this fact, and from now on connects the connecting valve (17). is closed to stop the pump (18).

If there is no abnormality in the pump, determine whether there is water in the water tank (15) by checking the open/closed state of the float switch (20). (20) OFF ) has a connecting valve (17).
Open and output to the drive circuit (40) and pump (18)
Rotate it in the opposite direction to drain the water from the water tank (15) to the washing tank (3).
Move to V. If there is no water in the water tank (15) (float switch (20) ON), open the water supply valve (35) until the liquid level switch 25) closes and drain the washing tank (3). water supply.

When the liquid level 1'/te (25) closes while the pump (18) is rotating in reverse, the connecting valve (17) is immediately closed and the pump (18)
) to complete the liquid return. Also, while the bong is rotating in reverse, the water in the water tank (15) runs out and the float switch (20
) is closed, the reverse rotation continues for 11 seconds from that point to complete the liquid return. This is a float switch (
20) is closed, there is still some water left in the water tank (15), and there is also water in the connecting waterway (16) other than the water tank, so drain all of this water and remove it from the washing tank. This is to reduce waste of water as much as possible by returning to (3). If the liquid level switch (2q) is not closed at this point, the water supply valve <35) is opened to supply water until it is closed.

If the liquid level switch (25) does not close even if the pump (18) continues to rotate in reverse for 3 minutes, or if the float switch <20
) does not close, it is determined that there is something wrong with the pump as described above, the connecting valve <17> is closed, and the pump (18>) is stopped.

The microcomputer (23) then stores the pump abnormality and does not operate the pump (18) in subsequent operations.

Figure 9) shows the above-mentioned "liquid movement" which is the gist of the present invention.

A flowchart of the process is shown in which the microcomputer (23) first determines whether or not the liquid movement occurs after the occurrence of a pump abnormality based on the stored contents.
) Drain as shown in the figure, but do not move the liquid. If there is no abnormality in the pump, the microcomputer (23) determines whether there is water in the water tank (15) based on the open/closed state of the float switch (20), and
5) If there is water inside (float switch (20) OF
F) does not move the liquid, but drains the water in the washing tub (3). This is because if there is dirty water in the water storage tank (15) and you move the liquid from the washing tank (3), the moved liquid may become dirty and cannot be reused. ) If the liquid moves even though there is water in it, it is a water storage tank (15)
This is to prevent water from overflowing from the top end.

If there is no water in the water tank (15) (float switch <
20) ON), the presence or absence of water in the washing tub (3) is determined, and if there is no water (liquid level switch (25) OFF), the liquid is not moved and the process proceeds to the next process. When there is water (liquid level switch (25) ON), open the connection valve (17), and after 10 minutes, output to the drive circuit (39) to rotate the pump (18) in the forward direction, and then open the washing tub (3). Transfer the water inside to the water tank (15). 10 seconds after this means that the connection waterway (16
) and the pump (18) are expelled by the water transferred from the washing tub (3), and when the pump (18) rotates, it is provided to ensure normal operation of the pump and to suppress foaming caused by air. It's time.

Even after rotating the pump (18) for 3 minutes, the liquid level switch (
25) does not open, it is determined that there is something wrong with the pump, and the microcomputer (23) stores this. After the pump malfunction occurs, close the connecting valve <17>, stop the pump (18), and drain the water in the washing tub <3> by opening the drain valve (10>).The pump (18) will no longer operate. .

When transferring the liquid after the second rinsing process, when transferring the rinsing water to the water tank (15), and when the rinsing switch knob (26) is on the water injection rinsing side, or If you remember performing water rinsing during the second rinse, (even though water rinsing was performed), press the rinse selector knob (2
6) may be adjusted to the rinsing side, so if you pour in water, the microcomputer (2)
3)) Perform the following operation. When the liquid level switch (25) opens the connecting valve (17) within 55 seconds, the pump (18>) rotates forward until 55 seconds have passed, and the connecting valve (17) remains open. When the liquid level switch (25) opens after 55 seconds, the pump (18) is stopped at that point and the connection valve (25) is opened.
17> Close. In either case, the liquid level switch (25)
The connecting valve (
17> and keep the pump (18> stopped).

For normal liquid movement other than the above, 15 seconds after the liquid level switch 25) is opened, the connecting valve (17) is closed, the pump (18) is stopped, and this state is maintained for 45 seconds. Open the connecting valve (17) for just a second and pump (18)
Rotate clockwise and drain the water seeping out from the clothes into the water tank (15).
Send to. In other words, even if there is no liquid in the washing tank (3) (outer tank (2)), the clothes still contain the liquid, so the liquid seeps out of the clothes for 45 seconds and is poured back into the water tank (1).
5) for reuse.

Also, when rinsing is performed in the second rinse, there is a lot of water in the washing tank (3) due to water rinsing, and if all of it is transferred to the water tank (15), the water tank (
15) may overflow, so connect the connecting valve (17).
After 55 seconds have elapsed since opening, the connecting valve (17) is closed to stop the pump (18).

Next, a tank cleaning process for automatically cleaning the inside of the water tank (15) will be explained based on the flowchart in FIG. (10). For tank cleaning, the microcomputer (23) first determines based on the stored contents whether or not the pump abnormality has occurred, and if the pump abnormality has occurred, the tank is not cleaned and the process proceeds to the next step. If there is no pump abnormality, there is no water in the water tank (15) and there is water in the washing tank (3).
0> and the liquid level switch (25), open the connecting valve 17). When the connecting valve <17) is opened, water moves from the washing tub (3) to the water tank (15) side, and as explained in the above-mentioned liquid movement, first the connecting waterway <16) and the pump (1
8) Expel the air inside and output the output to the drive circuit (39) after 1 second from the IJFI configuration of the connecting valve (17) to rotate the pump (18) forward and open the drain valve (1o).

The forward rotation of the pump (18) stirs the water transferred to the water tank (15) to wash away dirt adhering to the water tank wall. The pump 18) is driven until the liquid level switch (25) is opened. Unlike $ movement, the drain valve (10) is open, so after the pump (18) stops, the water in the water tank (15) is drained through the connecting waterway (16) and the drain valve (1o). This action causes the water tank (15) (especially the lower part) to
, the connecting waterway (16), and the inside of the tank 18) are automatically cleaned.

Pump (18) rotates forward for 3 minutes! If the liquid level switch (25) does not open even if the liquid level switch (25) continues, the microcomputer (23) determines that something is wrong with the pump and stops the pop/pump (18). During the draining and dewatering steps after tank cleaning, the connection valve (17) is kept open as described later, so the water with dissolved dirt in the water storage tank (15) is drained during the draining and dewatering steps. It does not remain in the water tank.

Next, the drainage process will be explained based on FIG. (11).

During the draining process, if the microcomputer (23) remembers that it is after the tank cleaning process, the drain valve (1
0), open the connection valve (17) at the same time, and open the water tank (17).
Also perform drainage from step 5. Drainage is continued until 1 minute and 15 seconds have passed after the liquid level switch (25) is opened, but draining is continued until 2 minutes and 3 minutes have passed.
If the liquid level switch <25) does not open even after 0 seconds, the microcomputer (23) determines that there is an abnormality in drainage, closes the connection valve 17) and the drain valve (10), and stores this fact. The drainage abnormality is erased from the memory of the microcomputer (23) by opening the upper lid <42> and once opening the lid switch 41), and then turning the lid switch (41)
When you close it, the water will start draining again.

Here, the meaning of clearing the memory of drainage abnormality by opening the upper cover (42) is as follows. The first action the user normally takes is to open the top cover (42) to take out the laundry, thinking that the washing is complete, and at this time there is water in the washing tub (3). If the operation is interrupted and you realize that there is something wrong with the drainage, and the cause is, for example, that you forgot to turn down the drain hose, you can immediately resume operation by turning down the drain hose and closing the top cover 42). . In the dehydration process shown in Fig. (12), if the micro pump unit (23) remembers that it is after the tank cleaning process, the connecting valve (17) is opened during the dehydration operation, and the water storage tank is (15) Drain the remaining water inside. In the dehydration operation, first, it is determined whether the upper lid (42) is closed or not by checking the open/closed state of the lid switch (41).
Only when the lid switch (41) is ON), the drain valve operating solenoid <12> is operated to open the drain valve (10), release the brake, and switch the clutch to dewatering.
Turn on the power to the right rotation drive circuit (37) and allow the motor (7) to rotate to rotate the washing tub (3). The motor (7) stops rotating when the remaining operation time for dewatering reaches 30 seconds, and the solenoid <12) is cut off to suppress noise when the brake is applied.

The glue cent dewatering process in Figure (13) is a combination of the above-mentioned draining process and dehydrating process, and the liquid level switch (25)
The dehydration operation begins as soon as the opening occurs.

The reversal in Fig. (14) is that in the push washing course selected by the course selection/start switch (33), the drive circuit (37) is first energized for 1.2 seconds to turn on the motor (7), that is, the rotary blade (6). Rotate clockwise, stop for 0.7 seconds, then connect the drive circuit (3
After energizing 8) for 12 seconds and rotating motor 7) counterclockwise,
．． The basic cycle is to stop for 9 seconds and repeat the cycle 6 times. In other courses selected with the course selection/start switches (28) to (32), the drive circuit (37) and the driver
8) Apply electricity and reverse the motor (7). Although not shown in the flowchart, if the t-switching knob (25) is set to the water injection rinsing side during the rinsing process,
At the same time as turning over, open the water supply valve (35) and perform water rinsing.

Next, according to the flowcharts in Figures (5) to (7),
The overall operation of the washing machine with water tank of this embodiment will be explained. t
When the tA switch (22) is turned on, the microcomputer (23) starts operating, resets the output terminal of the microcomputer, and then clears the internal data write memory (RAM) to the initial state. When any one of the course selection/start switches (28) to (33) is input, a course corresponding to this input is set. Then, within 3 seconds, the course selection/start switch (2
If any of the information in 8) to (33) cannot be input, start driving on the set course, then press the start switch (
28) - (33) Manual efforts will not be accepted and course changes will not be allowed.

Another start switch (28) to (33) within 3 seconds
If any one of these is input, a course based on this new start switch is set. When the same start switch (28) to <33) is pressed twice in succession within 3 seconds, a careful course is activated, and the washing process time, rinsing process time, and spin-drying process time can be set longer. Also,
When the reuse selector switch (34) is set to the (water tank) drain position and any of the start switches (28) to (33) is pressed, the water tank drain course is set.

Therefore, first, the (water tank) drainage course will be explained.

This drainage course opens the connecting valve (17) and the drain valve (10), and also opens the top lid (42) and opens the lid switch/ch (41).
) is open and the liquid level switch (25) is open (there is no water in the washing tub (3)), open the water supply valve (35) for 1 minute after starting operation, and close the water supply port (36). Supply water.

If you connect the external hose to the water supply port 36) here,
This hose leads water to the water tank (15) side and t+ii
Dirt in the water tank (15) that did not come off during the tank cleaning process described above can be easily cleaned. The water led to the water tank (15) is immediately discharged because the connecting valve (F) and the #L water valve (10) are opened. Of course, the interior of the washing tub (3) can also be easily cleaned using this port.

The reason why the water supply valve (35) is opened only when the liquid level switch (25>) is open is because there is liquid in the washing tub (3), and if the drain hose is not turned down, the water supply valve (35) is opened only when the liquid level switch (25) is open. mouth(
36) Water may overflow when water is supplied, so this is for safety reasons.

Also, if you close the lid (42) and the lid switch (41), the water supply valve (35) will not open, so the water tank (15) will not open.
Only the washing tank (3) can be drained.

Connecting force (17) and I-[Water valve (1o) closes after 3 minutes,
The buzzer (43) sounds to notify the completion of the (water tank) drainage course.

Next, the push washing course is special, so other normal washing 71
II: The case of J-S (fully automatic course, semi-automatic course, wash only course, rinse dehydration course, dehydration only course) will be explained.

First, determine whether the set course is a rinse dehydration course or a dehydration only course, and if it is a dehydration only course, select the
7) Proceed to the final dehydration shown in the figure. If neither course is selected, perform the liquid return process shown in Figure (8), and then
) If there is water, wash it! Move to (3). When the liquid level switch (25) is opened, it is determined whether it is a careful course or a standard course, and if it is a careful course, 15
For 10 minutes in the case of the standard course, perform the washing process by inverting as shown in Figure (14).In other words, rotate the rotor blades (6) for 1.2 seconds on each side with a 0.7 second stop. .

After finishing the washing process or starting the rinse/dehydration course.
When the reuse switch (34) is in the soap water reuse position, the liquid movement shown in FIG. 9 is carried out to move the water to the water tank (15). In the case of a simple washing course, a buzzer <43) is sounded to notify the completion of the washing process.

At the end of the wash only course, if the reuse selector switch (34) is set to the soap water reuse position, move the liquid for 1 minute and 30 seconds to the dehydration step shown in Figure (12) and start operation. This allows you to take out the laundry in a dehydrated state without getting your hands wet. Then, put another laundry in the washing machine 1MII and return the soapy water that was transferred to the water tank 15). It can be reused and washed by washing.

If you only have a wash course, use the wash lFJ as described above.
Since the operation is stopped with the liquid remaining in the tank, there is no need to get your hands wet when taking out the laundry, or to move or restore the liquid, thereby reducing time.

In cases other than the above, drain water as shown in Figure 11 and dehydrate as shown in Figure 12 for 1 minute and 30 seconds before proceeding to the first rinsing process. If there is water in the water tank (15) when draining starts (float swig - (20) OFF)
During the draining and dewatering, the connecting valve (17) is also opened to drain the water in the water tank (15).

The first rinse is for 2 minutes after water supply (14)
The process can be completed by reversing the diagram, and after completion of the process, if the reuse selector switch (34) is in the rinse water reuse position for purposes other than the rinse water dehydration course, perform tank cleaning as explained in Figure <10>. Clean the water tank (15).

What this means is that when rinsing water is reused, the water in the washing tub at the end of the second rinsing process is transferred and stored in the water tank, or the water at the end of the 1st rinsing process is Instead of draining the water in the washing tank, use it for washing the tank and store it.Clean the water tank as much as possible so that the water after the second rinsing process does not get dirty in the tank. It's for a reason.

The reason why tank cleaning is not performed in the rinse dewatering course is that drainage abnormalities such as the drain port not being tilted down may not be discovered if tank cleaning is performed.

In other words, the rinsing and dewatering course is to execute the range shown in the process diagram in Figure (4), but at the start of execution, the washing tub (
3) If there is no liquid in tank 151, you will not be able to find any abnormality in the drainage during the first rinsing process or during dewatering, and even if you continue to clean tank 151 after the first rinsing process, No drainage pattern was found. (When cleaning the tank, the pump (18) forcibly moves the liquid from the water tank from the washing tank, so the liquid level switch (25) opens, and at that point, the process proceeds to reset dewatering.

In other words, /1:/&lThe washing tub only rotates with water being distributed in the tub and the water storage tank. ) In this state, if you perform the second rinse with water, the water will drain into the washing tub (3).
) can be hidden away. Therefore, in the case of the Sugi dehydration course, the 2-minute period (13) is performed without cleaning the tank.
Proceed to the reset dehydration shown in the figure, where you can discover any water abnormalities. This 2 minute interval is the time after the liquid level switch (25) is opened (reset).

Next, water is supplied and the process proceeds to the second round. For this rinsing, the above-mentioned inversion is performed for 3 minutes in the careful course and 2 minutes in the standard course.

When the second nailing process is completed, as shown in flow chart 1 in Figure (7), in the case of the semi-automatic course, the washing tank (3) is filled with water and the operation is terminated, and the microphone [1]
If the computer (23) remembers that there is an abnormality in the pump, it will notify you of this, and if it does not, it will sound the buzzer (43) to notify you of the end and then return to the initial state. The buzzer in case of pump abnormality is
10 intermittently in shorter cycles than the buzzer at the end of the course
It beeps for seconds, and after 10 seconds, the display lamp (not shown) continues to blink.

If it is not a semi-automatic course but a fully automatic course or a dehydration only course, proceed to the final dehydration process. This dehydration is lyce /
However, before performing this reset dehydration, if the reuse selector switch (34) is in the rinse water reuse position, move the liquid and remove the rinse water from the washing tub (3). Transfer the water to the water tank (15).

On the other hand, when the water reuse selector switch (34) is in the no-reuse position (indicated in the flow chart as neither rinse water reuse nor soap water reuse), tank cleaning is performed. This is the reuse switch (3) mentioned above.
4) When the washing tank is in the position of rinsing water reuse, the liquid in the washing tank is not simply drained, but is used for i-purification, similar to the tank cleaning performed after the first rinse cycle. This is done to remove as much dirt as possible from the water tank (15) and connecting waterway (16).
The reason why we use the water after the sanding process is because it is the cleanest water.

The final glue cent dehydration time is 5 minutes and 3 minutes in the careful course.
0 seconds, and 3 minutes 30 seconds on the standard course. When the operation is finished, the microcomputer (23) notifies the pump if there is any abnormality in the memory, otherwise it sounds the buzzer (43) to notify the end and then returns to the initial state. The above is the case of a normal washing cycle.

The special wash cycle, the push wash cycle, is used to wash delicate fabrics such as sweaters and blankets.

(F) Effects of the Invention The water storage tank of the present invention (;I In the case of a washing machine, when reusing the liquid, the liquid transfer process from the washing tank to the water storage tank is carried out after the liquid has run out in the washing tank. Once the water supply to the water tank is stopped,
During this time, the liquid contained in the clothes is allowed to seep out, and the water is restarted to be fed to the water tank, allowing the seeped liquid to be stored in the tank, allowing for as much liquid as possible to be reused. The ratio is high.
