1 is a perspective view showing a general washing machine, Figure 2 is a side cross-sectional view showing a typical washing machine.

In general, the washing machine is fixed to the cabinet (2) to form the exterior, as shown in Figure 1 or 2, and suspended by the support member (4) inside the cabinet (2) and at the same time wash water is received An outer tub 6, an inner tub 10 rotatably installed in the outer tub 6, and a washing blade 8 disposed at a bottom thereof, and disposed below the outer tub 6, and the washing vane 8. ) And a motor (12) for driving the inner tank (10), a power transmission device (14) for selectively supplying the driving force of the motor (12) to the washing blade (8) and the inner tank (10), and the cabinet ( 2) is configured to include a microcomputer 16 to control the driving of the washing machine built in one side.

Here, the top cover 18 that forms the upper part of the washing machine is mounted on the upper end of the cabinet 2, and the base 20 provided with legs is mounted on the lower end of the cabinet 2.

The top cover 18 has an access hole (not shown) is formed in the center of the laundry, the lid 22 is opened and connected to one side to enable the opening and closing of the access hole, the rear portion of the outer tank (6) A water supply hose 24 and a water supply valve 26 for supplying the wash water are installed.

In addition, the outer tank 6 is provided with a drain valve 28 and a drain hose 30 for draining the wash water to the outside, and a temperature sensor 32 for detecting the water temperature of the wash water on one side of the outer tub, and washing An electrode sensor 34 for sensing conductivity of water is installed.

The electrode sensor 34 has a terminal portion 34a for measuring the potential difference between the wash water and the washing water and the received two terminals, and calculates the conductivity of the wash water from the potential difference measured by being connected to the terminal portion 34a. It is comprised by the conductivity calculation part 34b.

The temperature sensor 32 and the electrode sensor 34 is connected to the microcomputer 16 to transmit the detected water temperature and conductivity of the wash water.

The microcomputer 16 calculates the hardness and detergent amount of the wash water from the water temperature and the conductivity of the received wash water, and controls the driving of the washing machine by setting a washing algorithm according to the calculated value.

In addition, one side of the top cover 18 is provided with a display unit 36 for informing the consumer of the operating state of the washing machine, the display unit 36 is typically a liquid crystal display (LCD) or a light emitting diode (LED). Is produced.

The display unit 36 is connected to the microcomputer 16 to display washing conditions and washing conditions of the washing machine to the consumer.

In the conventional washing method of the washing machine configured as described above, the washing water is supplied to the outer tub 6 through the drain valve 24 and the drain hose 26 according to the quantity of water injected into the inner tub 10.

At this time, when washing is started, the water temperature of the wash water supplied by the temperature sensor 32 is sensed, the conductivity of the wash water supplied by the electrode sensor 34 is sensed, and the detected water temperature and conductivity Is transferred to the microcomputer 16.                         

The microcomputer 16 obtains the hardness of the wash water by analyzing the water temperature and conductivity of the received wash water, and calculates the amount of detergent of the wash water from the hardness and the water temperature of the wash water.

When the hardness and detergent amount of the wash water is calculated as described above, the microcomputer 16 resets and optimizes the washing algorithm according to the hardness and detergent amount of the washing water, and the washing is performed according to the set washing algorithm.

However, the washing method according to the related art functions of the temperature sensor 32 and the electrode sensor 34 even when the quality of the wash water is incorrectly detected by the temperature sensor 32 or the electrode sensor 34. Since it is impossible to stop the washing, it is not possible to prevent the incorrect washing algorithm from being set according to the water quality of the washing water that has been sensed.

That is, the water temperature and conductivity of the wash water are factors that determine the hardness and detergent amount of the wash water. If an inappropriate washing algorithm is set, the washing machine is not provided with a function for adjusting the operation of the temperature sensor 32 or the electrode sensor 34, and washing is performed according to an inappropriate washing algorithm.

The present invention has been created to solve the above problems, the purpose of the present invention is provided with a function to adjust the operation of the temperature sensor and the electrode sensor in the washing machine, more suitable according to the operation of the temperature sensor and the electrode sensor The laundry algorithm is set to provide a washing method of the washing machine that can improve the washing performance of the washing machine.

Washing method of the washing machine of the present invention for realizing the above object is the first step of setting the operation of the temperature sensor and the electrode sensor after the power is applied to the washing machine, the temperature sensor and electrode sensor set in the first step According to the second step of determining the operation mode of the sensor according to the presence or absence of operation, the third step of setting the washing algorithm according to the operation mode of the sensor determined in the second step, and according to the washing algorithm set in the third step Characterized in that the washing is made in a fourth step.

Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

3 is a flowchart illustrating an example of a washing method of a washing machine according to the present invention.

Here, the same reference numerals as the above-mentioned drawings indicate the same members.

In the washing method of the washing machine according to the present invention, as shown in FIG. 3, in the first step, the operation of the temperature sensor 32 and the electrode sensor 34 for detecting the water quality of the washing water is set when power is applied to the washing machine. (See step1, 2)

That is, the operation unit 38 of the washing machine is provided with an operation button for adjusting the operation of the temperature sensor 32 and the electrode sensor 34, the operation of the sensor is set by the user as necessary.

Such a method for setting the operation of the sensor may be performed by the user in operation of the temperature sensor 32 and the electrode sensor 34 for more efficient washing in a situation in which the user correctly recognizes various washing conditions and whether the sensor is broken in advance. This method is used when setting arbitrarily.

Therefore, when the user knows in advance the failure or bad state of the sensor to operate the operation button to stop the operation of the sensor.

On the other hand, the washing machine is provided with a function for adjusting the operation of the sensor itself, when the power is applied to the washing machine to check the failure and failure of the temperature sensor 32 and the electrode sensor 34, the temperature sensor If 32 or the electrode sensor 34 is determined to be faulty or defective, the operation is automatically stopped.

Such a method for setting the operation of the sensor is performed irrespective of the user to prevent the erroneous detection due to the failure and defect of the temperature sensor 32 and the electrode sensor 34, and is automatically performed at each washing operation. Washing performance is secured stably.

In the second step, the operation mode of the sensor is determined from the operation mode data according to the operation of the temperature sensor 32 and the electrode sensor 34 set in the first step, and the operation mode of the sensor is determined by the display unit of the washing machine. Displayed at 36 (see step 3, 4).

The operation mode data is classified according to the operation of the temperature sensor 32 and the electrode sensor 34 and is given a operation mode. The operation mode data is pre-stored in an inactive memory built into the washing machine and loaded when the power is applied.

That is, the operation mode of the sensor is determined from the operation mode data according to the operation of the sensor set in the first step, and the operation mode of the determined sensor is displayed on the display unit 36 to inform the user.

In more detail, as shown in Table 1 below, when the operation of the temperature sensor 32 and the electrode sensor 34 is stopped, the operation mode of the sensor is set to '1', and the display unit 36 has a ' S1 'is displayed.

In addition, when the temperature sensor 32 operates normally while the operation of the electrode sensor 34 is stopped, '2' is set as an operation mode of the sensor, and 'S2' is displayed on the display unit 36.

In addition, when the temperature sensor 32 and the electrode sensor 34 operate normally, '3' is set as an operation mode of the sensor, and 'S3' is displayed on the display unit 36.

In the third step, an appropriate washing algorithm is set according to the operation mode of the sensor determined in the second step (see step 5, 8, 9, 11, 12, and 13).

That is, when the operation mode of the sensor is '1', since the operation of both the temperature sensor 32 and the electrode sensor 34 is stopped, the water temperature and conductivity of the wash water are not detected, and thus the Water quality grasping becomes impossible and thus a standard washing algorithm is set.

This standard washing algorithm is previously input to the microcomputer 16 of the washing machine, and is a washing algorithm set by determining the quality of the wash water as a standard.

In addition, when the operation mode of the sensor is '2', since only the temperature sensor 32 is normally operated, the water temperature of the washing water is detected by the temperature sensor 32, and the washing algorithm is detected according to the detected washing water temperature. Is set.

Typically, the washing algorithm is determined according to the water temperature and hardness of the washing water and the amount of detergent. The hardness and detergent amount of the washing water are determined by the water temperature and conductivity of the washing water detected by the temperature sensor 32 and the electrode sensor 34. Is calculated.

As described above, when the operation mode of the sensor is '2', the conductivity of the wash water is not detected because the electrode sensor 34 does not operate, and thus the hardness value of the wash water detected during pre-washing or the microcomputer The washing algorithm is set by considering the standard hardness value stored in (16) as the conductivity of the wash water.

Here, the factor influencing the setting of the washing algorithm is the water temperature of the washing water, and it is preferable that the conductivity of the washing water and the amount of detergent do not affect the setting of the washing algorithm. Therefore, when the operation mode of the sensor is '2' as described above, the second washing algorithm is determined according to the hardness of the wash water and the amount of detergent calculated by the water temperature of the wash water.

On the other hand, when the operation mode of the sensor is '3', since the temperature sensor 32 and the electrode sensor 34 operate normally to detect the water temperature and conductivity of the wash water, the hardness of the wash water from the water temperature and conductivity of the wash water. And the amount of detergent is calculated to set the optimal washing algorithm.

That is, the water temperature is sensed by the temperature sensor 32 and the conductivity is sensed by the electrode sensor 34, and the hardness and detergent amount of the wash water by the microcomputer 16 from the detected water temperature and conductivity. This is calculated, and an appropriate washing algorithm is set according to the washing water temperature, hardness, and detergent amount. Therefore, when the operation mode of the sensor is '3' as described above, the third washing algorithm is determined according to the hardness of the wash water and the amount of detergent calculated by the water temperature and conductivity of the wash water.

In the fourth step, the washing is performed according to the washing algorithm set in the third step.

In the washing method of the washing machine of the present invention configured as described above, the operation mode of the sensor is determined by the operation of the temperature sensor and the electrode sensor, and an appropriate washing algorithm is set according to the operation mode of the sensor so that the washing is performed. And washing is performed by the optimal washing algorithm according to the operation of the electrode sensor has the advantage that the washing performance of the washing machine is improved.                     

In addition, the operation of the temperature sensor and the electrode sensor can be easily adjusted by the user directly operating the operation unit of the washing machine, there is an advantage that the operating mode and washing algorithm of the sensor most suitable by the user directly set according to the washing conditions. .

In addition, the washing machine is provided with a function for inspecting the failure and failure of the temperature sensor and the electrode sensor internally, and if the sensor is determined to be a failure or failure, the operation of the sensor is stopped, so that the failure and failure of the temperature sensor and the electrode sensor According to the operation mode of the appropriate sensor is automatically set there is an effect that the degradation of the washing performance is prevented.
