The present invention relates to a drum type washing machine for washing laundry in a drum rotating about a horizontal axis or an inclined axis.

Background Art [0002] Conventionally, in a drum type washing machine having a transverse drum, in a washing stroke, water is contained in an outer tank to a predetermined washing level, and the drum is rotated at a predetermined rotational speed such that laundry does not stick to the drum. Using a baffle formed on the circumferential surface of the ladle, the laundry is lifted to the top and dropped to the bottom, so-called tumbling is performed to wash the laundry. Also in the rinsing stroke, water is contained in the outer tank to a predetermined rinsing level (same level as the washing level), and the laundry is tumbled and rinsed by washing the laundry in the same manner as the washing stroke (see Japanese Laid-Open Patent Publication No. 2003-93777).

In the conventional drum type washing machine, the rinsing performance is reduced due to the fact that the amount of rinsing is small compared to the vortex type automatic washing machine which puts a lot of water in the washing dehydration tank and stirs the laundry by rotating the rotary blade to rinse the laundry. Tends to fall. For this reason, the number of times of rinsing was normally performed three times in the drum type washing machine, compared with having two vortex fully automatic washing machines. This was a factor and required long driving times.

In addition, when washing laundry made of pile fabrics such as towels (laundry of pile fabrics), the piles of surfaces were entangled with each other due to strong tapping during washing or rinsing, which caused agglomeration in laundry after drying. .

The present invention relates to a drum type washing machine, and aims to solve such a problem.

The drum type washing machine according to claim 1 of the present application for achieving the above object comprises a transverse drum installed freely in an outer tub, and rotates the drum in a state in which water is stored in the outer tub to perform a washing stroke and a rinsing stroke. A drum type washing machine which executes and washes laundry contained in a drum,

Rinse control in which the drum is filled with water up to a predetermined rinsing level in which the bath ratio (quantity / loading amount) is 4 or more in the rinsing stroke, and the laundry is stirred in the water contained up to the rinsing level. It is characterized by including the means.

In this configuration, water is contained in the outer tank in the rinsing stroke up to a predetermined rinsing water level such that the bath ratio (bath ratio in the dry state of the laundry) is 4 or more, preferably 5 or more. That is, water is loaded up to a water level (a large quantity) higher than a water level (amount) which has been subjected to tapping rinsing for a load of the same laundry. In addition, as in the conventional tapping rinse, it is not lifted away from the water and dropped into the water, and the drum is rotated to rinse the laundry so that the laundry is agitated mainly in water without being lifted away from the water. As the rotation control of the drum at this time, the rotation speed can be the same or smaller as compared to the conventional tapping rinsing, or the ON time when the drum is intermittently rotated can be considered. On the other hand, even at the same rotational speed, water becomes resistant as much as the quantity of water, so that the laundry cannot be raised high.

With such a configuration, since the laundry can be stirred and rinsed in a lot of water, that is, rinsing close to that of the vortex type automatic washing machine can be performed, the rinsing performance is improved. In addition, since the laundry is not hardly beaten, even pile fabrics such as towels can make the piles difficult to entangle, thereby reducing agglomeration after drying.

In addition, the drum type washing machine according to claim 2 includes a transverse drum provided freely in an outer tub, and rotates the drum in a state in which water is stored in the outer tub to perform a washing stroke and a rinsing stroke to wash laundry contained in the drum. In the drum type washing machine

Washing control means for carrying out tapping cleaning of the laundry by containing water up to a predetermined washing level in the washing administration and rotating the drum so that the laundry does not stick to the drum inner circumferential surface;

In the rinsing stroke following the washing stroke, water is stored up to a predetermined rinsing level higher than the washing stroke, and the rotational speed of the drum is reduced compared to the washing stroke, or the ON time when the drum is intermittently rotated is shortened. And rinsing control means for rinsing the laundry.

In this configuration, in the rinsing stroke following the washing stroke, water is contained up to a predetermined level higher than the washing stroke. Then, rotational control is performed to reduce the rotational speed of the drum or to shorten the ON time when the drum is intermittently rotated as compared with the washing stroke. In this way, like washing in a washing stroke, it is not lifted away from the surface of the water and dropped into the water, but is hardly lifted away from the surface of the water.

By setting it as such a structure, the rinsing performance improves similarly to Claim 1, and the aggregation of the laundry after drying can be reduced.

Next, the drum type washing machine according to claim 3 includes a transverse drum provided freely in the outer tub, and rotates the drum in a state in which water is stored in the outer tub to perform a washing stroke and a rinsing stroke to wash laundry contained in the drum. In the drum type washing machine to wash,

In addition to the standard course, we offer a special course suitable for washing laundry that is easy to bind, such as towels.

In the washing process in the standard course, the first washing control means for holding the water up to a predetermined washing water level, and rotating the drum so as to prevent the laundry from sticking to the inner peripheral surface of the drum to perform washing and washing of the laundry;

In the cleaning process in the dedicated course, water containing water of a load equal to a predetermined washing level higher than the standard course is contained, and the rotational speed of the drum is reduced as compared with the cleaning process in the standard course, or the drum is intermittent. And a second washing control means for washing the laundry by shortening the ON time at the time of rotation.

In this configuration, in the washing operation in the exclusive course, water is loaded to a predetermined washing level higher than the standard course for the laundry of the same load. Then, rotational control is performed so as to reduce the rotational speed of the drum or to shorten the ON time when the drum is intermittently rotated as compared with the cleaning stroke in the standard course. In this way, like tapping cleaning in a special course, it is not lifted away from the water surface and dropped into the water, but hardly knocked away from the water surface, or gently washed, or the laundry is stirred in the water. Clean the laundry. On the other hand, in the cleaning administration of this dedicated course, it is preferable in terms of cleaning performance to make the drum operation time, that is, the cleaning time longer than the standard course.

According to such a configuration, in the exclusive course for washing towels and the like, the laundry is not knocked out strongly by increasing the quantity of water in the washing process while avoiding dropping the laundry at a high position. It can make a pile difficult to entangle and can reduce the agglomeration after drying.

6 is a block diagram of an electric system of the drum type washing machine of the present embodiment having the above configuration. The control unit 50 (corresponding to the washing control means, the first washing control means, the second washing control means, and the rinsing control means) is composed mainly of a microcomputer (microcomputer) including a CPU, a ROM, a RAM, a timer, and the like. Based on the control program stored in the ROM, various controls are executed to perform the operation operations of each cycle of washing, rinsing, dehydration and drying.

The controller 50 is provided with a key input signal from the various operation keys formed on the operation panel 5 to give the user various settings and instructions, and a water level sensor that detects the water level stored in the outer tank 10. 52), the drum outlet temperature sensor 53 for detecting the water temperature at the time of washing or rinsing, the temperature at the outlet side of the drum 13 at the drying stroke, and the coolant temperature for detecting the temperature of the coolant after dehumidification at the drying stroke. In order to detect the ambient temperature of the drum type washing machine, which is the temperature which is affected by the sensor 54 and the motor 20, the atmospheric temperature sensor 62 disposed on the control board and the supply voltage (power supply voltage) from the commercial power source are supplied. From the voltage detecting circuit 63 for detecting, the speed sensor 64 for detecting the rotational speed of the motor, the bubble detecting sensor 55 for detecting the occurrence of abnormal bubbles in the outer tub 10, and the like.

This load driving unit 51 includes an inverter circuit (inverter means, output means). The inverter circuit outputs a drive voltage to the motor 20 in accordance with the duty ratio determined by the controller 50 based on the rotation speed detected by the speed sensor 64.

Therefore, the drum type washing machine of the present embodiment will be described taking the control operation of the washing operation as an example of the standard course. Hereinafter, the flowchart of FIG. 7 will be described.

When the start key 5b is pressed and operation is started, the control part 50 first determines the load amount of the laundry in the drum 13 (step S1). For example, the drum 13 is raised to a predetermined low rotational speed (140 rpm), and the load applied to the drum 13 at the length of the rise time of the rotational speed between the predetermined rotational speeds at this time is obtained, and the The load amount is determined based on the load. That is, since the load to the drum 13 becomes large, so that the load amount is large, on the contrary, it is determined that the load amount is large, so that the load to the drum 13 is large. Then, the washing water level and the rinsing water level are determined based on this load amount.

Next, a washing stroke is performed. The control unit 50: washing control means and first washing control means first supplies water to the washing water level determined according to the load amount (step S2). When water (detergent solution) is filled up to the washing water level, the drum 13 is rotated to wash the laundry (step S3). In this washing stroke, the drum 13 is rotationally controlled as follows. That is, firstly, the drum 13 is lifted in the drum 13 so that the laundry is lifted and dropped (tumbled), so that a predetermined first rotational speed (for example, 45 rpm), a predetermined ON-OFF time (for example, 10 seconds ON-3 seconds OFF), for a predetermined time (e.g., 3 minutes). Next, the rotational speed is lowered, and a predetermined second rotational speed (eg, 30 rpm), a predetermined ON-OFF time (eg, 10 seconds ON-3 seconds OFF, so that the laundry rolls near the bottom of the drum 13). ) Is rotated for a predetermined time (for example, 30 seconds). Then, after rotating for the predetermined time again at the first rotational speed and ON-OFF time, the rotational speed is increased at this time, so that the laundry lightly sticks to the inner wall surface of the drum 13 (eg, a predetermined third rotational speed (for example, , 60 rpm) and a predetermined ON-OFF time (e.g., 10 seconds ON-3 seconds OFF), for a predetermined time (e.g., 30 seconds). This repeats this operation.

At the first rotational speed, the laundry is patted and washed. At the second rotational speed, the laundry is scrubbed. At the third rotational speed, the detergent liquid in the laundry is partially removed, so that the new detergent liquid penetrates the laundry. That is, in this washing stroke, the washing of the laundry is mainly carried out, and the washing power is improved by adding scrubbing and penetrating washing to the tapping washing, as compared with only tapping washing.

When the predetermined washing time elapses in this way, the rotation control of the drum 13 is stopped, it drains from the inside of the outer tank 10 (step S4), and a washing stroke is complete | finished. Then, the drum 13 is rotated at a high speed to perform intermediate dehydration, and the detergent powder contained in the laundry is discharged together with water (step S5). In this way, the process moves to the rinsing cycle.

When the rinsing stroke is started, the controller 50 (rinsing control means) first supplies water up to the rinsing water level determined according to the load amount (step S6). 8 is a table showing the washing water level and the rinsing water level corresponding to the load of laundry, and as shown in this table, the rinsing water level is higher than the washing water level at the same load amount. That is, in the rinsing stroke, the yield is higher than that in the washing stroke. At this time, the rinse water level is a water level at which the bath ratio (amount / load amount) in the dry state of the laundry is 4 or more, preferably 5 or more, and the quantity is higher than that in the conventional drum type washing machine for the same load amount. It is increasing.

When water is supplied to the rinsing water level, the drum 13 is rotated to rinse the laundry (step S7). In this rinse stroke, the drum 13 is rotationally controlled as follows. That is, a fourth ON speed (e.g. 45 rpm) equal to or lower than the first rotation speed at the time of tapping cleaning of the washing stroke, and a short ON time (e.g. 4 seconds) compared to the ON-OFF time at the tapping cleaning, The drum 13 is rotated for a long OFF time (eg 6 seconds). At this time, the laundry in the drum 13 is stirred in the mainly contained water without being lifted far from the water surface, as shown in Fig. 9B. As a result, water penetrates into the laundry, and the detergent powder is discharged from the laundry and diluted with the contained water. The rinsing at this time is not a tapping rinse in which the laundry is dropped from the upper part of the drum 13 performed in the conventional drum type washing machine as shown in FIG. 9A, but is a rinse close to that of the vortex type automatic washing machine.

In this way, when the predetermined rinsing time has elapsed, the rotation control of the drum 13 is stopped, drainage is carried out from the inside of the outer tub 10 (step S8), and the first washing stroke is completed. Then, in order to perform the second rinsing stroke, the drum 13 is rotated at high speed to perform intermediate dehydration, and the detergent powder in the laundry which has not been exhausted by the first rinsing is discharged together with water (step S9). , S10). In this way, the flow shifts to the second rinsing cycle, and the same rinsing as the first rinsing is performed. When the second rinsing cycle is finished, the final spin speed is higher than that of the intermediate spin and the spin time is longer, and the water in the laundry is sufficiently discharged (step S11). Subsequently, the process shifts to the drying administration to dry the laundry (step S12), and the washing operation ends.

Thus, in the drum type washing machine in this embodiment, the rinsing stroke is not as hard as the conventional rinsing stroke or the washing stroke, but the amount of water is increased in comparison with the conventional rinsing stroke or the washing stroke. Since the rinsing close to the vortex type automatic washing machine which is stirred at is performed, the rinsing efficiency of the laundry is good, and the rinsing performance can be improved. Thereby, the number of times of rinsing which was three times conventionally can be reduced by 2 times, and the time required for washing operation can be shortened. Moreover, even if the laundry of pile fabrics, such as a towel, is hard to entangle a pile, the piled up after drying can be reduced.

On the other hand, by performing the above rinsing operation, not only the laundry of the pile fabric but also the tangling of the hair on the surface of the laundry of the fleece fibers can be reduced, and the occurrence of fluff can also be suppressed.

On the other hand, in this drum type washing machine, besides courses such as a standard course as a washing course, a special course for exclusively washing laundry which is easy to stick together such as pile fabrics or laundry which is easy to cause fluffs such as fleece fabric can be provided. In the washing stroke of this dedicated course, the washing water level is controlled to be the same as the rinsing water level in the rinsing stroke of the standard course under the control of the controller 50 (second washing control means), that is, than the washing level of the standard course. In this water level, rotation control of the same drum 13 as that of the rinsing stroke is performed so that the laundry is washed by stirring in water without being hardly beaten. In addition, the rinse stroke is the same as the rinse stroke of the standard course.

By providing such a special course, the laundry of the pile fabric can be washed well while suppressing agglomeration, and the laundry of fleece fiber can be washed well while suppressing the occurrence of fluff.

Hereinafter, although one Example of the drum type washing machine of this invention was described, this invention is not limited to the said Example, A change and correction can be suitably implemented within the range of the meaning of this invention.

In the present invention, the rinsing performance is improved because the laundry can be rinsed under a lot of water by rinsing, that is, rinsing close to that of the vortex automatic washing machine can be performed. In addition, since the laundry is not hardly beaten, even pile fabrics such as towels can make the piles difficult to entangle, thereby reducing agglomeration after drying. In addition, in the exclusive course for washing towels and the like, in order to prevent the laundry from being beaten strongly by washing the laundry at a higher position while increasing the amount of water than the standard course in the washing process, even the pile fabric such as the towel is piled up. It can make it hard to grow, and the aggregation after drying can be reduced.
