If you have questions, don’t hesitate to ask your teacher for assistance. Recognition of Prior Learning (RPL) You have already some basic knowledge and skills covered in this module because you have been working for some time; on already completed training in this area. If you can demonstrate competence to your teacher in a particular skill, talk to your teacher so you don’t have to undergo the same training again. If you have a qualification or Certificate of Competency from previous trainings show it to him/her. If the skills you acquired are consistent with and relevant to this module, they become part of the evidence. You can present these for RPL. If you are not sure about your competence skills, discuss this with your teacher. After completing this module, ask your teacher to assess your competence. Result of your assessment will be recorded in your competency profile. All the learning activities are designed for you to complete at your own pace. In this module, you will find the activities for you to complete and relevant information sheets for each learning outcome. Each learning outcome may have more than one learning activity. This module is prepared to help you achieve the required competency, in receiving and relaying information. This will be the source of information that will enable you to acquire the knowledge and skills in “Maintaining and Repairing a Rice cooker” independently at your own pace with minimum supervision from your teacher.

Fuse - A protective device in the current path that melts or breaks when current exceeds a predetermined maximum value. Half Wave - A diode rectifier that converts AC to pulsating DC by Rectifier eliminating either the negative or positive alternation of each input AC cycle. Leakage - Small undesirable flow of current through an insulator or dielectric. Light Emitting - A semiconductor diode that converts electric energy into Diode electromagnetic radiation at a visible and near infrared frequencies when its pn junction is forward bias. Output - Terminal at which a component, circuit or piece of equipment delivers current, voltage or power. Power Supply - Electrical equipment used to deliver either AC or DC voltage. Primary - First winding of a transformer. Winding that is connected to the source as opposed to secondary which is a winding connected to a load. Printed Circuit - Insulating board containing conductive tracks for circuit Board connections. Rectification - Process that converts alternating current to direct current. Rectifier - Diode circuit that converts AC to pulsating DC. Regulated - Power supply that maintains a constant output voltage

under changing load condition. - Component made of material that opposes the flow of current and therefore has some value of resistance. - Electromechanical device that has a rotating shaft connected to one terminal capable of making, breaking a connection to one or more other terminals. - Illustration of an electrical or electronic circuit with the components represented by their symbol. - Output winding of a transformer. Winding that is connected to a load. - Also called a short. Low resistance connection between two points in a circuit typically causing excessive current. - Metallic alloy used to two metal surfaces. - Process of ing two metallic surfaces to make an electrical by melting solder (tin and lead) across them. - Tool with an internal heating element used to heat surfaces being soldered to the point where the solder becomes molten. - Mechanical insulating upon which a device is fabricated. - Electrical device having two states, ON (closed) or OFF (open). - Sequence of operations intended to the correct operation or malfunctioning of a piece of equipment or system. - Inductor with two or more windings. - Systematic approach to locate the cause of a fault in an electronic circuit or system. - Known as a multitester.

INFORMATION SHEET 1.1 Rice Cooker Rice Cooker     

This self-contained kitchen appliance, is used primarily for cooking rice. It is used to prepare steamed rice and keep them warm after cooking. It consists of an insulated case containing a removable cooking pot. A heating element is located between the two containers, usually controlled by a thermostat. The cooking pot is usually calibrated to ensure proper proportions of the rice and water.

Application and Uses of Rice Cooker Rice cooker are used both in home and commercial kitchens for various purposes:  To cook rice  To keep rice warm  Could also be used as a steamer  Cooks automatically

PROPER HANDLING OF A RICE COOKER How to use a rice cooker? Before using any other accessory, make sure that the power unit is on a suitable work surface and switch to off. Put the protective cover over the drive that you will not be using rice cooker.

How the rice cooker operates? In most rice cookers, the rice and the water are poured in at the start of cooking. The heater then brings the water to boiling point, during which the rice absorbs the water and expands. After the present time, the rest of the water is boiled away and the machine either shuts off or switches to ‘ keep warm” mode. Some models allow s to add flavorings before or during the cooking.

Major Parts and their Functions

Power Cord - is a cord that temporarily connects an electrical appliance to an electrical power source. The term is generally used for cables using a power plug to connect to a single-phase.

. Cast Heater - A part of a rice cooker that produces heat to the aluminum pan. This serves as a heating element of the rice cooker.

Mica heater- consists of an etched-foil sandwiched between layers of mica. Installed by clamping to heat sinks, mica heater provide the ultimate temperature and wattage capability for fast warm-up.

Thermal fuse – is a cutoff which uses a one-time fusible link. Unlike the thermostat which automatically resets itself when temperature drops, the thermal fuse is more like an electrical fuse.

Thermostat assembly- a device, as in a home heating system that automatically responds to temperature changes and activates switches controlling the equipment.

4

Fluro pan- A part of a rice cooker where the rice is placed.

Outer Lid assembly - one of the major parts of a rice cooker and which serves as a wife of an aluminum pan, because this part is responsible to cover the bowl or an aluminum pan..

Body assembly- A part of a rice cooker in which the label are Usually found and the holder of the outer lid assembly.

Switch assembly - A part of a rice cooker that control the whole operation automatically.
