Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a water supply control device for an automatic washing machine that performs a series of washing, rinsing, and dehydrating operations for clothes and the like.

Conventional technology Conventionally, the water supply control device of this type of self-blade seat washing machine includes a course setting device that sets the washing time and water flow strength in four stages depending on the type of fabric and degree of dirt, and a water supply temperature that sets the water supply temperature in four stages. The user manually switches the water temperature setting device according to the type and amount of laundry to be operated each time a washing operation is performed.

Problems to be Solved by the Invention In such conventional automatic washing machines equipped with a course setting device and a water temperature setting device, the user can judge the type of laundry and
Appropriate water temperature settings must be made according to the type of water.
If the settings are incorrect, there are drawbacks such as clumped laundry and insufficient dirt removal.

The present invention aims to solve these problems by automatically setting the water temperature according to the type of laundry.

Means for Solving the Problem In order to solve this problem, the present invention provides a course setting means for setting the washing paddle time and water flow in N stages (N is a natural number) according to the type of cloth, and a course setting means for setting the washing paddle time and water flow in N stages (N is a natural number) according to the type of cloth. course information generating means for generating control information regarding the n-th (l≦n≦N) course set from the output of the means and the course data stored in the storage means; and a temperature of water supplied to the wash basin. water supply setting means for setting the water supply in X stages (X is a natural number), and the Xth (1≦X≦X) water supply set from the output of this water supply setting means and the water supply data stored in the storage means. The water supply information generation means for generating control information, the course information generation means, and the output of the water supply information generation means are used as inputs, and when the output of the course information generation means is inputted for the first time, the information corresponding to the nth course is preliminarily inputted. The water supply system includes a control means for controlling a hot water supply valve and a water supply valve driving means so as to supply water as set.

With this configuration, for example, when you set a course to wash laundry items that are sensitive to heat, such as tools, the water supply is not automatically set to only provide hot water, which prevents the laundry from shrinking. can. Furthermore, when a course for washing heavily soiled laundry is set, water-only water supply is not automatically set, so that insufficient stain removal can be prevented.

Embodiments Hereinafter, embodiments of the present invention will be described with reference to FIGS. 1, 2, and 3.

FIG. 1 is a block diagram showing the configuration of an embodiment of the present invention. K) is a course setting means that sets the washing time and water flow in N stages (N is a natural number) depending on the type of laundry and how dirty it is. (2) is a course information generation means, which includes the output of the course setting means (1) and the storage means (3).
The output and the receiver are input. Here, the storage means (3) stores data regarding the n-th course, data for supplying water in accordance with the course, and the like. The course information generating means (2) generates control information output regarding the nth course set by the course setting means (1). (4) is a water supply setting means that sets the temperature of water supplied to the washing tub in X stages (X is a natural number). (5
) is a water supply information generating means, which generates control information output according to a predetermined water supply setting from the output of the water supply setting means (4) and the data of the storage means (3). The course information generating means (
2) and the water supply valve driving means (8) to open and close the hot water supply valve and the water supply valve to control the inflow of hot water and water into the washing machine. It also controls the pulsator driving means (9) to rotate and stop the pulsator. Although not shown in the drawings, the system is configured so that displays are displayed according to the course and water supply.

FIG. 2 is a cross-sectional diagram showing the specific configuration of this embodiment.

00) is a washing tub, and a pulsator drive means (
A pulsator αD rotationally driven by 9) is provided. Course setting means (1) (is a button switch,
It is located at a position that is easy for the user to operate. The water supply setting means (4) is also a bushing switch, and is provided at the same position as the course setting means. The Q2+ is a microcomputer that uses a built-in program to determine the water supply and water supply, and generates signals to drive the hot water valve, water supply valve, and pulsator, respectively. Specifically, the storage unit (12a) stores course data, water supply data, appropriate water supply data suitable for the course, etc.; the input unit (12b) receives the outputs of the course setting means and the water supply setting means; an output section (12c) that outputs control signals to the hot water supply valve drive means (7), the water supply valve drive means (8), and the pulsator drive means (9); and the storage section (12a).
, an input section (12b), and an output section (12c), and has an arithmetic control section (126) that performs data comparison operations. That is, the arithmetic control section (12d) performs the functions of the cone information generating means (2), the water supply information generating means (5), and the control means (6) as shown in FIG. 71' of FIG. Note that a3 is a hot water valve that is opened and closed by the hot water valve driving means (7), and (1, 1) is a hot water valve driving means (7).
8), the water supply valve is opened and closed by (1 is the start switch for starting the washing work.
) is a setting display LED for water supply.

Next, the operation of this embodiment will be explained. FIG. 3 shows the main part of a flowchart controlled by a microcomputer (1?J).

Generally, after the user puts the laundry into Wash@A (10),
Add detergent and set the course according to the laundry. This operation causes the microcomputer (12) to
When it is determined that the whirl course llW [ffl course] is selected in Step 11, the water supply setting display LED is turned on in Step C2.
to W A RM. In step CI, the hot water supply valve (131) is opened via the hot water supply valve drive means (7J), and the water supply valve CI is opened via the water supply valve drive means (8) to allow hot water and water to flow into the washing tub.

In addition, step c! If it is determined in step 11 that the course is other than the whirl course, it is determined in step C7 what course the next course is, the water supply setting display LED corresponding to the course determined in step ω is turned on, and the water supply valve Q31 is turned on. Or open the water supply valve ■. Next, the microcomputer takes step (2)
When the water level reaches the set level in step 6), proceed to the next washing step with Step Assistant.

In this way, in this embodiment, if the user sets the course according to the type of laundry and how dirty it is, the appropriate amount of water can be automatically supplied to the laundry. This can prevent it from becoming insufficient.

Effects of the Invention The present invention includes a course setting means according to the type of cloth, a storage means, a course information generation means, and a set corresponding to the nth course when only the output of the supply water temperature generation means is input. The device is equipped with a control means for controlling the hot water supply valve and the water supply valve driving means so as to supply water as set in advance, so that if the user sets the course according to the laundry, This makes it possible to provide the optimal water temperature depending on the level of dirt.
