TOUCH CONTROL PANEL ASSEMBLY

OUTLINE OF TOUCH CONTROL PANEL

The touch control section consists of the following units.

(1)Key Unit

(2)Control Unit (The Control Unit consists of Power Unit and LSI Unit).

The principal functions of these units and the signals com- municated among them are explained below.

Key Unit

The key unit is composed of a matrix, signals generated in the LSI are sent to the key unit through P110-P117. When a key pad is touched, a signal is completed through the key unit and passed back to the LSI through P100, P101, P102, P103, ANI6 and ANI7 to perform the function that was requested.

Control Unit

Control unit consists of LSI, ACL circuit, indicator circuit, power source circuit, relay circuit, buzzer circuit, synchro- nizing signal circuit, absolute humidity sensor circuit and back light circuit.

1)ACL

This circuit generates a signal which resets the LSI to the initial state when power is supplied.

2)Indicator Circuit

This circuit consists of 40 segments and 16 common electrodes using a Liquid Crystal Display. The Liquid Crystal Display (LCD) is drived by LCD driver IC3.

3)Power Source Circuit

This circuit generates voltages necessary in the control unit from the AC line voltage.

In addition, the synchronizing signal is available in order to compose a basic standard time in the clock circuit.

4)Relay Circuit

A circuit to drive the magnetron, fan motor, turntable motor and light the oven lamp.

5)Buzzer Circuit

The buzzer is responsive to signals from the LSI to emit audible sounds (key touch sound and completion sound).

6)Synchronizing Signal Circuit

The power source synchronizing signal is available in order to compose a basic standard time in the clock circuit.

It accompanies a very small error because it works on commercial frequency.

7)Door Sensing Switch

A switch to “tell” the LSI if the door is open or closed.

8)Back Light Circuit

A circuit to drive the back light (Light emitting diodes LD10- LD15).

9)Absolute Humidity Sensor Circuit

This circuit detects moisture of the cooking food to allow its automatic cooking.

R-530EK specifications

The Sharp R-530EK is a notable microwave oven that combines functionality with innovation to enhance cooking convenience. With a sleek design and user-friendly interface, this model has earned a place in many kitchens around the globe.

One of the primary features of the Sharp R-530EK is its powerful microwave output. The oven boasts a maximum power of 900 watts, ensuring that food can be heated quickly and evenly. This power level allows users to prepare a variety of meals, from reheating leftovers to cooking dishes from scratch, in significantly less time than traditional cooking methods.

The R-530EK is equipped with a spacious interior, offering 25 liters of capacity. This ample space allows for cooking larger dishes or multiple servings at once. The turntable design ensures even cooking by rotating food during the heating process, further enhancing the microwave's efficiency.

Another standout feature of the Sharp R-530EK is its array of pre-programmed auto-cook menus. These presets simplify cooking by providing specific times and power levels for various types of food, including popcorn, pizzas, and oatmeal. Users can simply select the appropriate setting, and the microwave takes care of the rest, making it ideal for those who may not have extensive cooking experience.

The microwave utilizes advanced inverter technology, a feature that sets it apart from many conventional microwave ovens. Inverter technology allows for continuous and consistent power output, providing more precise temperature control. This means that delicate foods such as seafood or chocolate can be heated without the risk of overcooking or burning, resulting in better texture and flavor.

Additionally, the R-530EK is designed with multiple cooking functions that enhance its versatility. These include defrosting capabilities, grilling options, and even signals indicating the completion of cooking cycles. The easy-to-read digital display and intuitively designed buttons contribute to the overall user experience, making it accessible for individuals of all ages.

Moreover, this microwave oven ensures safety with features such as a child lock, which prevents accidental operation by little hands. The Sharp R-530EK is both an efficient and reliable addition to any kitchen, embodying the perfect blend of cutting-edge technology and practical design to meet the demands of modern cooking. With its impressive range of features and performance capabilities, it stands as a valuable tool for aspiring chefs and busy families alike.
