Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a washing machine equipped with a water absorption pump so that so-called bath water or the like can be used for washing.

[0002]

2. Description of the Related Art Conventionally, when bath water is used in a washing machine, a submersible motor built-in water absorption pump unit for transferring the bath water to the tub of the washing machine has been supplied. This water absorption pump unit has a structure in which one end of a water absorption hose is equipped with a water absorption pump, and the other end of this water absorption hose is faced to a tub of a washing machine or is connected to a water inlet of the washing machine. Is put in the bath water of the bathtub and the water absorption pump is driven in this state.

[0003]

However, in the above-mentioned conventional structure, since the water absorption pump is used while being immersed in the bath water of the bathtub, the service life of the water absorption pump itself is short,
In addition, since the tip of the water-absorbing hose is heavy and the power cord is also attached, there is a drawback that the handleability when transferring water to the tank is poor. Furthermore, since the power cord is submerged in the bath water, great consideration must be given to its insulating structure, resulting in high cost.

The present invention has been made in view of the above-mentioned circumstances, and an object thereof is to have a long service life of a water absorption pump, good handleability when transferring water into a tank, and a power source for the water absorption pump. An object of the present invention is to provide a washing machine in which the insulation structure of the cord can be simplified as compared with the conventional one, and further the pump efficiency of the water absorption pump is improved.

[0005]

[Means for Solving the Problems] A first means comprises a washing machine body having a tub, an agitator and required equipment such as a washing machine motor and having a water receiving portion for receiving water from a tap water. And a water suction pump incorporated into the main body of the washing machine, which has a suction port and a discharge port, discharges water sucked from the suction port and supplies the water to the tub, and one end has a suction port of the water suction pump. A water absorption hose connected to the side, the other end is arbitrarily arranged in a water storage part such as a bathtub, and a water passage from the water receiving part to the water absorption pump and the water absorption hose is configured to have a water supply valve, It is configured to include water filling means for filling the water suction pump and the water suction hose with water from the water receiving portion (the invention of claim 1).

A second means is the same as the first means, wherein the water filling means is connected to the first water supply valve, the second water supply valve, one end of which is connected to the suction port of the water absorption pump, and the other end of which is connected. One of the branch portions is in communication with the water receiving portion via the first water supply valve, and the other branch portion is in communication with one end of the water suction hose via the second water supply valve. The present invention is characterized in that it has a water channel (the invention of claim 2).

A third means is the same as the first or second means, except that a pump drive control means for driving the water suction pump after charging the water from the water receiving portion to the water suction pump and the water suction hose is provided. It has a feature (the invention of claim 3).

A fourth means is the water absorbing hose according to the first or second means, wherein the water-absorbing hose is provided at one end with a connector detachably connected to a mating connection target portion, and a magnet is provided on the connector. A magnetic detection means is provided in the vicinity of the mating connection target portion, and when the connection of the connector is detected by the magnetic detection means, water from the water receiving portion is filled into the water absorption pump and the water absorption hose side. (The invention of claim 4). The fifth means is characterized in that, in the first or second means, an activated carbon filter is provided at the other end of the water absorbing hose (the invention of claim 5).

[0009]

In the first means, the washing machine main body is provided with the water absorption pump, one end of the water absorption hose is connected to the suction port side of the water absorption pump, and the other end is arbitrarily arranged in the water storage part such as a bathtub. Since the water absorption pump is not submerged in water, the life of the water absorption pump itself is extended, and there is no water absorption pump at the tip of the water absorption hose, and the power cord is also attached. There is no need to do so, and the handling property when transferring water to the tank is improved. Furthermore,
Since the power cord is not submerged in the bath water, the insulation structure can be simplified as compared with the conventional structure.

Further, in this first means, the water absorbing means for filling the water from the water receiving portion into the water absorbing pump and the water absorbing hose is provided. Therefore, prior to the driving of the water absorbing pump, The water absorption hose can be filled with water, that is, it can be primed,
As a result, the water suction pump does not suck air and does not run idle, and it is possible to pump up bath water or the like from the beginning, resulting in good pump efficiency. Moreover, since there is no no-load operation, the pump motor will not overheat.

In the second means, by opening both the first water supply valve and the second water supply valve, it becomes possible to fill the water absorption pump and the water absorption hose with the water from the water receiving port, which is relatively You can prime the water with a simple structure. Further, if the first water supply valve is opened and closed while the second water supply valve is closed, water can be supplied to and stopped in the tank through the water absorption pump.

In the third means, since the water suction pump and the pump drive control means for driving the water suction pump after filling the water suction hose with the water from the water receiving portion are provided, the third means automatically operates after priming. Water transfer to the tank can be started.

In the fourth means, when the connection of the connector is detected by the magnetic detecting means, the water from the water receiving portion is filled into the water absorbing pump and the water absorbing hose, so that the water absorbing hose is disconnected. The water will not be splashed out of the washing machine without being filled with water.

In the fifth means, since the activated carbon filter is provided at the other end of the water absorption hose, when the bath water is used for washing, the dirt contained in the bath water can be adsorbed and the bath can be cleaned cleanly. You will be able to transfer water. In particular, in this case, since the water suction pump and the water suction hose are primed, water can be sufficiently sucked even by an activated carbon filter which is a relatively dense filter.

That is, when air is in the water absorption hose when the water absorption pump is driven (priming is not made),
Since the suction power of the water absorption pump for air is weak, if the water absorption hose is equipped with an activated carbon filter, which is a relatively dense filter, it will be difficult to suck up the air in the water absorption hose and eventually it will absorb water. It takes a considerable amount of time, and it is practically difficult to use the activated carbon filter.

However, in the fifth means, since the water suction pump and the water suction hose can be primed before driving the water suction pump, there is no problem even if the activated carbon filter is used.

Then, one end 17a of the pipe 17 is connected to the suction port 9a of the water suction pump 7, the other end is branched, one branch 17b is connected to the water receiving port 5, and the other is branched. The part 17c is formed so as to communicate with and connect to one end 20a of the water absorption hose 20 described later. Further, the first water supply valve 18 is interposed in one branch portion 17b of the pipe 17, and the second water supply valve 19 is interposed in the other branch portion 17c of the pipe 17. The first water supply valve 18 and the second water supply valve 19 are electromagnetic valves.

On the other hand, the washing machine main body 1 is provided with a water absorption hose 20, and the water absorption hose 20 has one end 2 thereof.
A pipe 17 in which 0a is the suction port 9a side of the water suction pump 7
Which is connected to the other branch portion 17c of the
b is arrange | positioned in the bathtub B as a water storage part.

As shown in FIG. 3, the water absorbing hose 20 is provided at its one end 20a with a connector 21 which is detachably connected to the tip of the branching portion 17c which is the mating connection target portion. , Magnet 2 in this connector 21
2 is provided. On the other hand, a reed switch 23, which is magnetic detection means, is provided near the tip of the branch portion 17c. A Hall element may be used as the magnetic detection means.

6 and 7, the water-absorbing hose 2 is shown.
The other end portion 20b of 0 is shown, and the other end portion 20b is shown.
The filter device 24 is attached so as to communicate with the opening of the. The filter case 25 in the filter device 24 has one end 25a inserted into the opening of the other end 20b, and the other end 25b of the filter case 25 is provided with a plastic suction port body 26. There is. The suction port body 26 is provided with a notch-shaped auxiliary suction portion 26a at its edge. Then, a mesh-shaped filter portion 27 having a relatively large mesh is formed.

Further, in the filter case 25, from the filter portion 27 side to the one end portion 25a side, a sponge filter 28, a relatively fine mesh-shaped filter portion 29, an activated carbon filter 30, and a slightly large mesh shape are arranged in this order. The filter part 31 is provided. The activated carbon filter 30 includes a cloth bag 30a and a relatively fine activated carbon 30b contained therein.

Next, FIG. 8 shows an electrical configuration. The control circuit 32 is configured to include a microcomputer, to which a signal is given from a switch input section 33, a hose connection detection circuit 34, a water level sensor 35, and a flow rate detection circuit 36 as a flow rate detection means. ing. Further, the control circuit 32 follows the operation program stored in advance and based on the input signals, the first water supply valve 18, the second water supply valve 19, the pump motor 1
2. The washing machine motor 37 and the drain valve 38 are drive-controlled via drive circuits 39 to 43, respectively, and the display section 44 is drive-controlled. This control circuit 32 is
In addition to controlling the washing operation, it also functions as pump drive control means.

The hose connection detection circuit 34 comprises the above-mentioned reed switch 23, and the connector 21 of the water absorption hose 20 is connected to the tip of the other branch portion 17c of the pipe 17 so that the reed switch 23 is connected. A connection detection signal is output when a switch operation, for example, a closing operation is performed. Further, in the flow rate detection circuit 36, when the blades 11 of the water absorption pump 7 are in a rotation-free state, the blades 11 rotate due to water flow, so that an induced voltage is generated in the coil 14 of the pump motor 12. Focusing attention and detecting the induced voltage or the frequency thereof, the flow rate of water according to the rotation speed of the blade 11 is detected.

That is, FIG. 9 shows a schematic structure of the pump motor 12, and when the permanent magnet 13 is rotated by the rotation of the blade 11, an induced voltage is generated as shown in FIG. 10 according to the rotation speed thereof. The frequency changes. FIG. 7A shows the case where the blade 11 has a relatively low rotation speed, in which case the induced voltage is low and the generation frequency is low (the cycle is long). FIG. 11B shows the case where the blade 11 has a relatively high rotation speed, in which case the induced voltage is high and the generation frequency is high (the cycle is short). Also,
FIG. 11 shows the relationship between the induced voltage and the rotation speed.
2 shows the relationship between the generation frequency and period and the rotation speed. By thus measuring the induced voltage or the generated frequency (cycle), the rotation speed of the blade 11 is detected, and the flow rate of water is detected based on this rotation speed.

FIG. 13 shows a flow chart of the water supply control into the tank in the control circuit 32. In this control, for example, the first water supply stroke in the washing operation is started. In this case, when the user wants to use the bath water, the connector 21 of the one end 20a of the water absorption hose 20 is connected to the tip of the branch portion 17c of the pipe 17,
Put the other end 20b of the water absorption hose 20 so as to be submerged in the water of the bathtub. If the user wants to use tap water, the water suction hose 20 is removed.

Therefore, in step S1 of FIG. 13, the first water supply valve 18 is opened. And it transfers to step S2 and judges whether the water absorption hose 20 is connected based on the signal from the hose connection detection circuit 34. Now, for example, assuming that the water suction hose 20 is disconnected (when tap water is used), the flow proceeds to step S3, and the flow rate of tap water per unit time is determined based on the signal from the flow rate detection circuit 36. , 10 liters per minute or less, more than 10 liters per minute and less than 15 liters per minute, or more than 15 liters per minute is detected. Thereafter, when it is determined that the water supply level in the tank reaches the set water level based on the signal from the water level sensor 35 (step S4), the first water supply valve 18 is closed (step S5).
This water supply process ends.

When it is detected in step S2 that the water suction hose 20 is connected (when using bath water), the process proceeds to step S6 according to "Y" in step S2. In step S6, it is determined whether or not the tap water flow rate detection result found in step S3 described above due to the previous use of the washing machine is 10 liters per minute or less. Water filling time t
Set a to "20 seconds".

Further, the flow rate detection result of tap water is 10 per minute.
If it exceeds the liter, "N" in step S6
In accordance with step S7, it is determined whether it is 15 liters per minute or less (whether it is more than 10 liters per minute and less than 15 liters per minute) and exceeds 10 liters per minute and 1 per minute.
If it is 5 liters or less, the process proceeds to step S9 and the water filling time ta is set to "10 seconds". Further, when the flow rate exceeds 15 liters per minute, step S
In accordance with “N” of 7, the process proceeds to step S10 and the water filling time ta is set to “5 seconds”.

Thereafter, as shown in step S11, the pump motor 12 is electromagnetically braked by, for example, regenerative braking, so that the blades 11 are prevented from rotating. And
It transfers to step S12 and opens the 2nd water supply valve 19. As a result, both the water supply valves 18 and 19 are opened, so that tap water is filled into the water absorption pump 7 and the water absorption hose 20 through the pipe 17 of the water filling means 8 and the both water supply valves 18 and 19. .

In this case, since the blades 11 of the water suction pump 7 are prevented from rotating, the water flow in the water suction pump 7 is satisfactorily blocked and the filling of water is ensured.
The time at which filling is completed at this time varies depending on the flow rate of tap water, but since the water filling time ta is set in advance according to the flow rate, the set water filling time is set as shown in the next step S13. Since the process waits for the time ta, it means that filling of water with just enough amount is being executed.

When the elapse of the water filling time ta is judged in this step S13, the process proceeds to step S14, the pump motor 12 is energized to drive the water absorption pump 7, and thereby the water absorption pump 7 and the water absorption hose. The water suction pump 7 is operated in a state where the water is filled in the water 20.
Thereafter, as shown in step S15, when it is determined that a predetermined time, for example, 5 seconds has elapsed, the first water suction valve 18
Is closed, that is, the supply of tap water is stopped. As a result, the bath water is sucked up and the discharge port 9a of the water suction pump 7 is discharged.
Is discharged from and supplied into the tank. In this case, dust and dirt contained in the bath water are removed by the filter device 24. In particular, relatively large dust is captured by the filter portion 27 of the suction port body 26 and the sponge filter 28, and dirt is adsorbed by the activated carbon filter 30.

According to this embodiment, the washing machine body 1 is provided with the water absorption pump 7, and the one end 20 of the water absorption hose 20 is provided.
Since a is connected to the suction port 9a side of the water suction pump 7 and the other end 20b is arbitrarily arranged in the bath B,
Unlike the conventional case where the water absorption pump is used in a state of being submerged in water, the service life of the water absorption pump 7 itself becomes longer, and
There is no water absorption pump at the other end, which is the tip of the water absorption hose 20, and there is no need to attach a power cord to the water absorption hose 20. As a result, handling is easy when transferring water into the tank. Furthermore, since the power cord is not submerged in the bath water, the insulating structure can be made simpler than before.

Further, according to this embodiment, since the water filling means 8 for filling the water from the water receiving portion 5 into the water absorbing pump 7 and the water absorbing hose 20 is provided, prior to the driving of the water absorbing pump 7, The water suction pump 7 and the water suction hose 20 can be filled with water, that is, priming can be performed, and as a result, the water suction pump 7 does not suck air and run idle, thus It is possible to pump up bath water etc. from the pump and the pump efficiency is good. Moreover, since there is no no-load operation state, the pump motor 12 does not overheat.

In particular, according to this embodiment, the water filling means 8
However, the first water supply valve 18, the second water supply valve 19 and one end 17a are connected to the suction port 9a of the water suction pump 7, the other end is branched, and one branch 17b is a water receiving port. 5 to the first
Of the other branch part 17c, which is connected through the water supply valve 18 of
Is one end 20a of the water suction hose 20 and the second water supply valve 1
Since it is configured to have a pipe 17 that is a water passage that is connected and communicated via 9, the first water supply valve 18 and the second water supply valve 19 are both opened so that the water receiving port 5 It becomes possible to fill the water absorption pump 7 and the water absorption hose 20 with this water, and it is possible to prime the water with a relatively simple configuration.

If the first water supply valve 18 is opened / closed while the second water supply valve 19 is closed, tap water is supplied through the water absorption pump 7 in an uncontrolled state (the blades 11 are free to rotate). It can be supplied to the tank and stopped. Thus, when water is supplied to the tank, the blades 1 of the water absorption pump 7
It is possible to detect the flow rate of tap water based on the induced voltage of the pump motor 12 generated with the rotation of 1 and its frequency. Focusing on this point, in the present embodiment, since the flow rate detection circuit 36 is provided, the flow rate of tap water can be detected, and the water suction pump 7 and the water suction hose 20 can be detected based on the detected flow rate. Since the water filling time is set, it is possible to fill the water in proper time without excess or deficiency.

Further, according to this embodiment, the water from the water receiving portion 5 is filled in the water absorption pump 7 and the water absorption hose 20 and then the water absorption pump 7 is driven, so that the water is automatically pumped after priming. It is convenient because you can start transferring water to the tank.

Furthermore, according to the present embodiment, when the reed switch 23 detects the connection of the connector 21, the water from the water receiving port 5 is filled into the water absorbing pump 7 and the water absorbing hose 20. Water hose 20
Water will not be refilled with the water removed and will not splash out of the washing machine.

Further, according to this embodiment, the water absorption hose 20
Since the activated carbon filter 30 is provided at the other end portion 20b of the above, when the bath water is used for washing, dirt contained in the bath water can be adsorbed cleanly, and clean water can be transferred to the tank. In this case, in particular, since the water suction pump 7 and the water suction hose 20 are primed, even the activated carbon filter 30, which is a relatively dense filter, can sufficiently suck water.

That is, when the water suction hose 20 is filled with air when the water suction pump 7 is driven (no priming is performed), the water suction pump 7 has a weak suction force to the air, and therefore the water suction hose 20 is relatively dense. If the activated carbon filter 30, which is a filter, is provided, the air in the water absorption hose 20 cannot be easily sucked up, and in the end, it takes a considerable amount of time to suck in the water, and the activated carbon filter 30 is actually used. Is difficult to use, and there is a problem that it is difficult to clean the bath water.

However, according to this embodiment, the water suction pump 2
Since water can be primed in the water absorption pump 7 and the water absorption hose 20 prior to 0 driving, the water absorption capacity of the water absorption pump 7 is sufficiently exerted, and water is sufficiently pumped up even if the activated carbon filter 30 is used. Therefore, it can greatly contribute to the purification of bath water.

When the filter device 24 is to be cleaned, the filter device 24 may be placed in an appropriate drainage place and the water absorption pump 7 and the water absorption hose 20 may only be filled with water. Since the water is discharged from 24, the dust attached when the bath water is pumped is discharged to the drainage place together with the water, and the filter device 24 can be easily cleaned.

Next, FIG. 14 shows a second embodiment of the present invention, in which the structure of the water filling means 51 is different. That is, the water filling means 51 includes the first water supply valve 5
2, the second water supply valve 53 and the water passage 54 are configured, but the water passage 54 has one end 54a connected to the water receiving port 5 and the other end having the water receiving port 54. It is branched into two parts on the downstream side when viewed from the 5 side, the first water supply valve 52 is interposed in one branch part 54b, and the second water supply valve 53 is interposed in the other branch part 54c. , Is connected to the suction port 9a of the water suction pump 7.

In this case, when bath water is used, the electromagnetic brake is applied to the pump motor 12 of the water suction pump 7 to close the first water supply valve 52 and open the second water supply valve 53. The water suction pump 7 and the water suction hose 20 are filled with tap water, and then the water suction pump 7 is driven and the second water supply valve 53 is closed. This causes the bath water to be pumped up and transferred into the tub of the washing machine. Further, if the first water supply valve 52 is opened while the second water supply valve 53 is closed, water can be supplied into the tank without passing through the water suction pump 7.

As the water passage, the structure of the pipe 17 which is the water passage of the first embodiment, and the water passage 5 of the second embodiment described above.
It is not limited to the configuration of No. 4, but various kinds can be considered. Further, the location and quantity of the water supply valve can be changed appropriately.

[0048]

As is apparent from the above description, the present invention can obtain the following effects. According to the invention of claim 1, since the water absorption pump is not used in a state of being submerged in water, the service life of the water absorption pump itself is extended,
In addition, since there is no water absorption pump at the tip of the water absorption hose and it is not necessary to attach a power cord, the handleability when transferring water to the tank is improved. Furthermore, since the power cord is not submerged in the bath water, the insulation structure can be simplified as compared with the conventional structure. Furthermore, the water suction pump and the water suction hose can be primed prior to the drive of the water suction pump, and as a result, the water suction pump does not suck air and run idle, and it is possible to pump bath water etc. from the beginning. The pump efficiency is good. Moreover, since there is no no-load operation,
The pump motor will not overheat.

According to the second aspect of the invention, by opening both the first water supply valve and the second water supply valve, it becomes possible to fill the water absorption pump and the water absorption hose with water from the water receiving port. It is possible to prime the water with a relatively simple structure.
Further, by opening and closing the first water supply valve with the second water supply valve closed, it is possible to supply and stop water supply into the tank through the water absorption pump. In this case, it is possible to detect the water supply flow rate based on the induced voltage or frequency generated in the pump motor of the water suction pump.

According to the third aspect of the invention, since the water suction pump and the water suction hose are filled with water from the water receiving portion and then the water suction pump is driven, the water is automatically transferred to the tank after priming. It's convenient to get started.

According to the fourth aspect of the invention, when the connection of the connector is detected by the magnetism detecting means, the water from the water receiving portion is filled in the water absorbing pump and the water absorbing hose side. Since water is not filled when the water is removed, it is possible to prevent water from splashing out of the washing machine.

According to the invention of claim 5, since the activated carbon filter is provided at the other end of the water absorption hose, when the bath water is used for washing, dirt contained in the bath water can be adsorbed cleanly, You can transfer clean water to the tank. Particularly in this case, since the water suction pump and the water suction hose are primed, water can be sufficiently pumped up without any trouble even with an activated carbon filter which is a relatively dense filter.
