Referring to the drawings to describe the above content in more detail as follows.

2 is a cross-sectional view showing the structure of a controller assembly for a washing machine according to the present invention, Figure 3 is a plan view of FIG.

As shown in FIG. 2, the present invention provides an electric equipment compartment 10 provided in a main body (see 1 in FIG. 1), a driving circuit board 20 provided at a bottom side of the electric equipment compartment, and an electric equipment compartment. A control panel 30 provided at the top and having a display on the top surface, a support panel 40 for supporting a bottom portion of the control panel, mounted on the driving circuit board and penetrating the support panel and the control panel And a light emitting means 60 which emits light at the periphery of the switch.

At this time, the light emitting means 60, one end is mounted to the drive circuit board 20 to emit light along the periphery of the switch 50, and the light emitting in a predetermined color when the switch is rotated left and right A light emitting element 61 which emits light in a predetermined color different from the predetermined color when the switch is moved up and down, and a supporter for supporting the light emitting element such that the other end of the light emitting element is positioned near the support panel 40; 62) is included.

In addition, as shown in FIG. 3, the light emitting device 61 accurately indicates the position of the switch 50 and evenly emits light to the entirety of the knob 51 which is a part of the switch to give a subtle aesthetic appearance. It is preferable that a plurality is provided along the circumference of the switch.

The light emitting device 61 is preferably a light emitting diode (LED) having a plurality of colors.

On the other hand, in order for the light of the light emitting device 61 to pass through the support panel 40 and the control panel 30 in order to diverge to the outside, the material of the support panel and the control panel corresponding to the light emitting device It is preferable that the material of a part consists of a transparent or translucent material.

In addition, the material corresponding to the light emitting device 61 of the support panel 40 and the part corresponding to the light emitting device of the control panel 30 is preferably made of a transparent or translucent material.

The present invention made as described above performs the following role.

First, the role of the switch 50 (hereinafter referred to as "rotary switch") provided in the washing machine is as follows.

As the customer rotates the dial knob 51 protruding on the control panel 30, the wiper (not shown) is also rotated along the circumferentially arranged contact portion (not shown), and the wiper has a specific function. The desired function is selected by the consumer pressing the knob when the contact point indicating the mode is reached. Therefore, the function mode is performed simultaneously with pressing the rotary switch.

That is, the rotary switch 50 controls the function mode according to the variety of types of laundry, such as jeans washing, wool washing, etc., which are diversified functions of the washing machine, and a function mode according to the amount of laundry, as one part instead of a plurality of buttons. You can do it.

In other words, as the consumer rotates the dial knob 51 of the rotary switch 50, the wiper is rotated. At this time, the wiper is rotated in contact with the contact portion, and thus the mechanical analog variation is converted into a digital quantity. The function mode is in a state where it can be performed, and when the consumer reaches the desired function mode, the consumer stops rotating the dial knob and presses the dial knob. At this time, the microcomputer (not shown) sends a pulse signal to the selected mode. ) To perform the desired function mode.

Therefore, the present invention can optimize the space of the controller assembly, as well as the cost of the number of parts by easily selecting a variety of functions with a single rotary switch 50 even without using a plurality of buttons Savings and simplifying the production process.

Second, the role of the light emitting means 60 is as follows.

As the functions of the washing machines are diversified, consumers have more and more choices, and they are increasingly demanding more and more complicated operation power. To alleviate this complexity, washing machines can be operated easily regardless of age or gender. Conditions should be provided in the washing machine.

One of them is the light emitting means 60, which indicates the position of the rotary switch as a predetermined color light so that the user can easily recognize the position of the rotary switch 50, which is the core of the controller, or a specific position. When pressing the rotary switch in the light of the color different from the color serves to accurately inform the location of the current washing course.

In addition, the operation of the light emitting means may be performed as follows.

First, the LED 61 starts to emit light in accordance with a time input (especially a dark night time) input to the microcomputer or starts to emit light when the user rotates the rotary switch 50.

Thereafter, the user rotates the rotary switch 50 to select a desired course among a plurality of washing courses. When the rotary switch reaches the washing course to be selected, the user presses the rotary switch to select the washing course. At this time, a tact switch (not shown) in which the shaft of the wiper is located behind the contact portion is selected. By pressing the light of a different color from the initial color is turned on the LED (61).

Therefore, as the LED 61 emits light at a specific washing course, it is easy to know what washing course is currently in progress, and the preparation for the next washing can be facilitated.

As described above, according to the present invention, the wiper and the contact of the rotary switch may be smoothly rotated while contacting each other, and thus, the desired contact may be selected.

Therefore, the consumer can select various washing courses while turning the rotary switch left and right.

In addition, the present invention displays the position of the rotary switch and the current position of the washing course selected by the rotary switch according to the light emitting means, so that the operation of the rotary switch becomes easier.

In other words, when washing in the dark night, the user can identify the rotary switch without turning on a separate fluorescent lamp, and even the grandmother or grandfather who is poor at operating the washing machine controller can easily recognize the position of the rotary switch and the washing course. The rotary switch can be easily operated.

In addition, the light emitting means can enhance the appearance of the product.
