The weight sensing unit 74 detects the weight of the deodorant introduced into the rotating tub 30. As a method for sensing the weight, a method using a current value sensed due to torque generated when the driving motor rotates, the weight sensing sensor Various weight sensing methods used conventionally, such as using a method, using an optical sensor, or using an infrared sensor may be used.

The control unit 75 is a microcomputer that controls the washing machine according to the operation information input from the signal input unit 71. When the water supply step is performed, the control unit 75 controls the water supply valve 42 and the rotating tank 30 to be driven. The water supplied from the water supply nozzle 44 is stored in the first heater 15 on the lower side of the water tank 20 without being introduced into the rotary bath 30.

In addition, the controller 75 detects the water supply level, determines whether the detected water level is a heater safety level, and when it is determined that the heater safety level is determined, the water supply is terminated and the first heater 15 is driven to drive the water in the water tank 20. Is heated to produce steam.

In addition, the controller 75 senses the temperature of the water heated by the first heater 15 and determines whether the detected water temperature is equal to or less than a predetermined temperature (preliminarily stored in the controller 75 according to the type of deodorant) and detects If the set temperature is less than or equal to the predetermined temperature, the driving time of the first heater 15 (the time from the first driving of the first heater 15) may supply the deodorizing substance with a predetermined amount of humidification depending on the weight of the deodorizing substance. In this case, the data obtained by the experiment is stored in advance in the control unit 75. At this time, the appropriate humidification amount is approximately 2% to 5% of the weight of the deodorant. If the driving time of 15) is longer than or equal to the predetermined time, the first heater 15 is turned off and the humidification step is completed.

In addition, after the control unit 75 performs proper humidification to the deodorant, in the deodorizing step, first, the drain valve 52 is driven to drain the water stored in the water tank 20 to discharge water from the water tank 20 to the outside. In addition, the blower fan 61 and the second heater 62 of the blower 60 are driven to supply hot air to the deodorant of the rotary tub 30. At this time, the drain valve 52 is kept open, the hot air supplied to the rotating tank 30 is discharged to the outside through the exhaust device 50 containing the odor particles to improve the deodorizing performance.

In addition, by rotating the rotary tub 30 at the same time as the supply of hot air, it is possible to further improve the odor separation effect.

In addition, the control unit 34 has a timer for countering the driving time of the first heater 15, and has a predetermined temperature (heating temperature of the stored water according to the type of deodorant) and a predetermined time (first according to the amount of deodorant). Data such as the driving time of the heater 15) is stored in a ROM table in advance.

The driving unit 76 drives the water supply valve 42, the drain valve 52, the driving motor 13, the first heater 15, and the blower 60 according to the driving control signal of the controller 75.

Next will be described the operation of the washing machine according to the present invention.

4 is an operation flowchart showing a humidification step of the washing machine according to an embodiment of the present invention, Figure 5 is an operation flowchart showing a deodorizing step of the washing machine according to an embodiment of the present invention.

First, to describe the operation of the humidifying step of the washing machine according to an embodiment of the present invention.

When the user puts the deodorant inside the rotating tub 30 and selects driving information such as a deodorizing course according to the material, the driving information selected by the user is input to the controller 75 through the signal input unit 71. In this way, the control unit 75 sets the heating temperature of the stored water to a predetermined temperature according to the material of the deodorant selected by the user.

In addition, the control unit 75 detects the weight of the deodorant introduced into the rotating tank through the weight sensing unit 74 (S100), and compares the detected weight with the stored data to determine the driving time of the first heater 15 for a predetermined time. Set to.

Subsequently, the water supply valve 42 is driven to supply water from the water supply nozzle 44 into the water tank 20 (S110). At this time, the controller 75 drives the rotary water tank 30 (S120). 20) the water supplied into the rotary tank 30 is not introduced into the rotary tank 30 by the centrifugal force by the rotation of the rotary tank 30, flows between the space between the rotary tank 30 and the water tank 20 to the bottom of the water tank 20 The water is stored in the first heater 15 side. At this time, the maximum water level of the water to be stored is lower than the lower height of the rotating tub so that water does not flow into the deodorant in the rotating tub (30).

Next, detect the water level of the water stored in this way (S130), and determine whether the detected water level is the heater safety level (level that the first heater can be completely submerged in water) (S140), if the heater safety level is a water supply valve ( 42) off to end the water supply step (S141).

Thereafter, the first heater is driven (S150), and the stored water is heated to generate steam. The deodorant is humidified using the hot steam generated in this way. At this time, the driving state of the rotating tub 30 is maintained for even humidification of the deodorant.

In addition, by sensing the temperature of the water to be heated (S160), it is determined whether the detected water temperature is below a predetermined temperature (S170). If the detected water temperature is less than the predetermined temperature, it is determined whether the heater driving time is more than the predetermined time (S180). If the heater driving time is more than the predetermined time, the first heater is turned off (S190), and the humidification step is terminated.

In addition, if the detected water temperature in step S170 is greater than the predetermined temperature, the first heater 15 is turned off (S171), and it is determined whether the driving time of the first heater 15 is longer than the predetermined time (S172). If the driving time of the first heater 15 is more than a predetermined time, the humidifying step is terminated.

In this way, it is possible to provide an appropriate humidification temperature and humidification amount according to the deodorant by varying the temperature of the water heated and the driving time of the first heater 15 according to the material of the deodorant and the amount of the deodorant, thereby preventing damage to the deodorant. The deodorizing effect can be improved.

Next, the control method of the washing machine according to the present invention enters the deodorization step after the humidification step is completed. First, the water stored in the water tank 20 is discharged to the outside by driving the drain valve 52. (S200) Thereafter, the air blower 60 is driven to heat the outside of the water tank 20 to heat the air, and then supply hot air to the deodorant in the rotating water tank 30. (S210) The air volume of the supplied hot air is determined by experiment. If the air volume increases, the internal temperature drops and the time for contacting the deodorant and the hot air can be shortened. Therefore, the wind speed that can increase the deodorization efficiency is determined experimentally.

In addition, the odor particles can be separated from the deodorant to some extent only by the supply of hot air, but in order to improve the deodorization efficiency, in one embodiment of the present invention, the rotary bath 30 is driven simultaneously with the supply of the hot air (S220). ), By rotating the forward and reverse rotation, it is possible to further improve the separation effect of the odor particles by the friction of the rotating tank 30 and the deodorant.

As such, the air containing the odor particles separated from the deodorant is exhausted to the outside through the exhaust device 50 to completely separate the odor particles from the deodorant.
