Description

  The present invention relates to a method for controlling the operation of a washing / drying machine capable of drying laundry after dehydration in a washing and dewatering tub.

  In the drying process after the dehydration process, the warm air generated from the heating device and blower is sent into the washing and dehydrating tub, and the laundry and dewatering tank and rotating blades are rotated during the drying process to loosen the laundry. There is a laundry dryer to dry the.

  This includes, for example, an outer box, an outer tub supported in the outer box, a laundry dewatering tub that is rotatably disposed in the outer tub, has an upper surface opened, and has a dewatering hole formed in the peripheral wall surface. A rotating blade disposed at the inner bottom of the laundry dewatering tank; and warm air supply means for supplying warm air into the laundry dewatering tank during a drying process, wherein the warm air from the hot air supply means is removed from the laundry The water is supplied directly from the upper surface opening of the water tank or from the upper part of the outer tank through the dehydration hole.

  In the washing and drying machine having such a configuration, the washing process, the rinsing process, the dehydration process, and the washing operation automatically proceed, and when the process proceeds to the drying process after the dehydration process is completed, the warm air generator is activated in this drying process. Wind is generated and this warm air flows into the washing and dewatering tank. Then, the moisture is vaporized by contacting with the moisture-containing laundry placed on the upper surface of the rotary blade on the bottom surface of the laundry dewatering tank. The hot air containing moisture from the laundry and having a high humidity is guided to the upper side of the laundry dewatering tub, and is exhausted from the upper surface opening to the outside of the outer box through the exhaust hole.

  The above operation is performed for a predetermined time to perform a drying process for drying the laundry (see, for example, Patent Document 1).

JP-A-10-216396

In the drying process, as described above, the heater is turned on and the blower fan is operated to supply warm air into the washing and dehydrating tub. However, the air that has not been heated while rotating the washing and dehydrating tub, that is, outside air is taken in. Even if this is brought into contact with the laundry, a flow of outside air (wind) can be created in the washing and dehydrating tub, and the environment becomes the same as when the wind is applied to the laundry, reducing the moisture contained in the laundry. A washing machine that performs drying using such cold air is also considered.

  However, the conventional washing machine only supplies either hot air or cold air during the drying process. For this reason, depending on the quality of the laundry, ambient temperature, humidity, etc., the moisture contained in the laundry can be sufficiently blown away by supplying only cold air without heating the heater. On the other hand, there are cases where moisture cannot be sufficiently blown by simply supplying cold air, but these cases cannot be flexibly handled.

  The object of the present invention is to solve the disadvantages of the conventional example described above, and when drying the dehydrated laundry, different drying methods are set depending on conditions such as the quality of the laundry, ambient temperature, humidity, etc., and it is suitable for the laundry. An object of the present invention is to provide an economical operation control method for a washing / drying machine that can select a drying method and can meet the needs of the user and can reduce running costs.

Since the present invention to achieve the object, an outer box, a water tub disposed in the outer box, and the washing and dewatering tank bored a number of water-removal holes is rotatably disposed in the water tank, washing and A blower fan that supplies air from the upper surface side of the dewatering tub into the washing and dewatering tub, a heater that heats air supplied from the blast fan to the washing and dewatering tub, and an inner bottom of the washing and dewatering tub In a washing / drying machine having a rotary blade, the first step of rotating the washing and dewatering tub while operating the blower fan with the heater turned off, the washing and dehydrating tub while operating the blower fan and the heater The second step of rotating, and the third step of rotating the rotor blades reciprocally while operating the blower fan and the heater were operated.

In this way, if the moisture contained in the laundry can be removed simply by supplying cold air depending on the conditions such as the quality of the laundry, ambient temperature, and humidity, the cold air is supplied by operating only the blower fan. In the case of thick laundry or in the case where the ambient temperature is low and the humidity is high, the fan is heated and the heater is operated to supply hot air. As described above, by appropriately selecting a drying method, it is possible to efficiently dry and meet the needs of the user. Further, it is economical because it is not necessary to operate the heater unnecessarily.

It is a drying process figure which shows embodiment of the operation control method of this invention. It is explanatory drawing of the washing-drying machine with which the operation control method of this invention is implemented.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 is a drying process diagram showing an embodiment of the operation control method of the present invention, and FIG. 2 is an overall explanatory view of the washing / drying machine in which the method of the present invention is implemented. A water tank 2 was slidably disposed therein, and a rotary blade 3 was disposed at the bottom of the water tank 2 and a washing and dewatering tank 4 having a number of dewatering holes 5 formed in the peripheral wall was provided.

  In the figure, reference numeral 6 denotes a balancer attached to the upper part of the washing / dehydrating tub 4, and 7 denotes a motor for rotating the washing / dehydrating tub 4 and the rotary blade 3. Further, a top panel 9 provided with a lid 8 is attached to the upper opening of the outer box 1.

  In addition to this configuration, means for drying the clothes in the washing and dewatering tub 4 is provided. As a means for supplying hot air, an air inlet 11 provided with a filter 10 is provided at a side portion of the outer box 1, and a duct 14 is provided between the water tank 2 in the outer box 1 and positioned downstream of the air inlet 11. In the duct 14, a blower fan 12 and a heater 13 as heating means are sequentially arranged. In the figure, reference numeral 15 denotes a mist nozzle for supplying mist-like water (mist) into the washing and dewatering tub 4.

  As warm air discharging means, an inner lid 16 is provided in the upper opening of the water tank 2, and a discharge port 18 provided with a filter 17 is formed in the inner lid 16. An exhaust port 19 is provided in the top panel 9 at a position above the discharge port 18.

  An intake air temperature sensor 20 using a thermistor or the like is provided between the filter 10 and the blower fan 12, and an exhaust gas temperature sensor 21 is attached to the lower surface of the water tank cover 2 a attached to the upper part of the water tank 2.

  In such a washing / drying machine, the drying process performed after the washing process is divided into the first process to the third process according to different types of drying operation patterns, for example, as shown in the process chart of FIG. In the case of 4, 5 kg, it set to the ventilation eco-drying process which ventilates the air which is not heated in the 1st process. In this air blowing eco-drying process, the heater 13 is not energized while rotating the washing and dewatering tub 4, and only the blower fan 12 is operated to supply cold air into the washing and dewatering tub 4 for further dehydration.

  As a result, the outside air sucked from the intake port 11 is supplied into the washing / dehydrating tub 4, the outside air contacts the laundry, and the laundry / dehydrating tub 4 has the same environment as when the laundry is exposed to the wind, The moisture contained in the laundry is reduced.

  In this case, when there is no inner lid 16 in the washing / dehydrating tub 4, centrifugal force is generated by rotating the washing / dehydrating tub 4, so that outside air can be taken into the washing / dehydrating tub 4. However, in the type having the inner lid 16, since the suction force of the outside air is not easily generated, the blower fan 12 is operated as described above to suck in air.

  Next, similarly, with the heater 13 turned off, only the rotary blade 3 is rotated to scrape off the clothes clinging to the wall surface of the washing and dewatering tank 4.

  The second step is by rotating the tank while drying the washing / dehydrating tub 4 and blowing the warm air heated by energizing the heater 13 into the washing / dehydrating tub 4 by the blower fan 12 and applying it to the clothes for drying. Heat drying. In this case, the number of rotations of the washing / dehydrating tub 4 is rotated at a high speed of, for example, 300 rpm for 1 minute in the first stage, and the clothes stored in the washing / dehydrating tub 4 are spread out. Make a hole in. Here, the reason why the high-speed rotation of 300 rpm is set to a short time of 1 minute is that if the time is longer than that, the clothes are crushed in the washing and dewatering tub 4 and biased outward.

  In the next stage, the flat clothes are rotated for 14 minutes at a low speed of 150 rpm to dry the clothes. And finally, only the rotary blade 3 is rotated 7 times, and the clothes are replaced in the washing and dewatering tub 4. Such an operation is repeated twice. During this time, the warm air supplied into the washing and dewatering tub 4 comes into contact with the clothing, and then is discharged from the discharge port 18 into the outer box 1 and further discharged from the exhaust port 19 to the outside of the machine body.

  In the subsequent third step, the rotating blades 3 are rotated to perform stirring and drying. A drying operation is performed for a predetermined time while rotating the rotary blade 3 while supplying warm air. After that, move the clothes in small increments and loosen them to adjust the imbalance. Finally, rotate the washing / dehydrating tub 4 at a high speed of 300 rpm for 1 minute to spread the clothing from the center of the washing / dehydrating tub 4 and the clothing does not get tangled. Like that. This is repeated until the end of drying.

  Finally, as a finish, the rotary blade 3 is rotated 5 times to loosen and dry the clothes.

  The air drying eco-drying process which is the first process and the heat drying process by the tank rotation drying which is the second process may be transferred to the heat-drying process after the air eco-drying process is first performed as described above. However, both strokes can be selected and set to be switchable.

  The user may selectively switch between the air blowing eco-drying process and the heat-drying process according to the needs, but it may be automatically performed according to conditions such as ambient temperature, humidity, and laundry cloth quality. Set to. Accordingly, when the ambient temperature is high, when the humidity is low, when the laundry is thin, or when the fabric is thin, the heater 13 is not energized and the outside air taken in is washed as it is. The blow drying process to be supplied into the cum dewatering tank 4 is automatically set.

  On the other hand, when the ambient temperature is low, the humidity is high, or the laundry is thick, it is difficult to dry just by blowing air. The heating and drying process to be supplied into the cum dewatering tank 4 is automatically set.

  Furthermore, in the present invention, the operation time of the air blowing eco-drying process is automatically set according to conditions such as ambient temperature, humidity, and laundry cloth quality. As a result, more detailed operation control is possible, and the operation time is not prolonged more than necessary.
