Detailed Lesson Plan in Servicing Consumer Electronic Products and System - Domestic Electronic Appliances I. II. III. IV. Objectives At the end of the lesson 80% of the students should be able to A. Know the use of Rice Cooker B. Identify the different parts and its function of the Rice Cooker C. Perform diagnose faults and defects of a Rice Cooker D. Troubleshoot and repair common problems of a Rice Cooker Subject Matter “Maintain/repair Rice Cooker” Materials Screw Drivers, Long Nose Plier, Side Cutting Plier, Rice Cooker, Hand Outs, VOM References: https://www.recipetips.com/glossary-term/t--34028/rice-cooker.asp http://infomagiccom.blogspot.com/ Procedure A. Preparation Teacher Activity Students Activity “Good Morning Class” “Good Morning Sir” “Let us start this day by thanking God and ask for his guidance. Mr. Kim Please lead the prayer” “Before you take your seat kindly pick-up pieces of paper and arrange your chairs.” “Ms. Secretary may I know who are the absentees for this day?” (Mr. Kim will stand in front and will lead the prayer) (The Secretary of the class will stand and tell who are the absentees for the day.) B. Motivation Teacher Activity Students Activity “When you hear the word Rice Cooker what comes in to your mind?” (Students will raise their hands) “An appliance used to cook rice” “Thank you, by this technology it can make our work easier right?” “Yes Sir” “It prepares the rice automatically, knowing when the rice reaches the proper temperature, it will switch from a cooking mode to a warming mode.” “Our topic deals about the parts and function of a Rice Cooker and how to repair common problems” C. Lesson Proper Teacher Activity Students Activity “Now we are going to study the different parts and function of a rice cooker” “As we all know that a rice cooker is an electric kitchen appliance that is used to cook rice right?” “These are the basic parts of the rice cooker” 1. Thermal fuse 2. Heating plate/ element 3. Magnetic thermostat 4. Thermal resistor/ thermistor (Mica) 5. On-off micro switch 6. Panel Led indicator 7. Power cord 1. Thermal fuse cut off function when the heat flow due to the damage exceeds the reasonableness of the rice cooker. It serve as a protective device. 2. It is fused with metal. Generate 300400 watts, depending on the type of a cooker. If damage to this section, it is not possible to repair. 3. In the thermostat there is a magnet and spring, at room temperature the magnetic force is greater than the spring force. Thermostat metal parts (parts in direct contact with the rice pot) censoring the heat of the pan if the heat has reached approximately 134 degrees Celsius. Metal when exposed to heat, the magnetic power is reduced so that the spring force is greater than the magnetic force. As a result, regardless of the magnetic spring (away) so that pressing the lever and push the switch lever. 4. It is covered by some sort of paper (mica) that function at the time of warming. This also serves as a thermistor, the greater the resistance when the heat increases. The greater the resistance, the incoming voltage is reduced, thereby reducing the heat generated power heater. So as to control the heat so that the heat of the cooker while warming remains in the range of 70-80 centigrade. “Yes Sir” Teacher Activity Students Activity 5. Serves to move the switch from cooking to warming position and vice versa. Button switch is pressed by a lever actuated by the thermostat automatically or manually via the button panel. 6. Comprising led indicator for cooking and warming position. 7. It is used to power the whole rice cooker. “Those are the basic parts and function of the rice cooker” “Now, I will teach you on how to fix the different problems of a rice cooker?” “These are the different problems and how to fix them” “ Problem-No Power Possible Cause- Damage plug, blown thermal fuse Remedy/Action Taken- Check the plug, replace thermal fuse” “Problem- After several minutes the led indicator switches to warm Possible Cause- Damage magnetic thermostat Remedy/Action Taken- Replace magnetic thermostat “Problem- The indicator is always warm Possible Cause- Loss contact of the on-off micro switch Remedy/Action Taken- Cleaning the contacts with contact cleaner” D. Activity Teacher Activity Identify the different parts of a rice cooker by putting the name of the parts in the actual rice cooker. Students Activity I will be grouping you into two groups (The student will be group into two groups) I will provide the rice cooker I will give you the name of the parts of the rice cooker (The student will put the name of the parts in the rice cooker) E. Generalization Teacher Activity Based on what you have learned in this topic, who can now share their learnings? “Thank you. How about the parts of a rice cooker, anyone? “Very Good, it is very important to know the different parts and function of a rice cooker and how to fix them.” V. Students Activity (Student will raise their hands) “I have learned that rice cooker is easy to understand and how to fix them” (Student will raise their hands) “I have learned that there are 7 basic parts of a rice cooker” 1. Thermal fuse 2. Heating plate/ element 3. Magnetic thermostat 4. Thermal resistor/ thermistor (Mica) 5. On-off micro switch 6. Panel Led indicator 7. Power cord Evaluation Direction: Read the following question and write the answer on the space provided. I. Identification: ________1. It is fused with metal. Generate 300-400 watts, depending on the type of a cooker. ________2. It is covered by some sort of paper (mica) that function at the time of warming. ________3. Serves to move the switch from cooking to warming position and vice versa. II. VI. Enumeration 4 to 10 parts of a rice cooker Assignment A. Follow up assignment 1. Research additional problems of a rice cooker 2. Per group, submit a wiring diagram of a rice cooker References: http://infomagiccom.blogspot.com Prepared By: Jeferson C. Enoposa
