• Sharp blades:
The mixer grinder should be used with alertness. If you use it without any caution, there are possibilities of injuring
your hands. These blades can be dangerous; therefore, you have to keep the jar away from children and pets.
• Repair and maintenance:
If there is any fault in the mixer, then the repairing cost can be very high. Some parts of the mixer grinders are very
expensive. It can also be difficult to maintain as dirt and food items easily get stuck in the bottom.
Application of Mixer Grinders:
One of the primary uses of mixer grinders is to grind spices. Indian cuisine is known for its use of spices, and hav-
ing a mixer grinder in your kitchen can make the task of grinding spices much easier and faster. Mixer grinders
are also used for making chutneys, which are an integral part of Indian cuisine. From coriander and mint chutneys
to tomato and onion chutneys, a mixer grinder can help you prepare these condiments with ease.
Another popular use of mixer grinders is for blending fruits and vegetables to make smoothies and shakes. This
is especially useful for those who want to include more fruits and vegetables in their diet but do not have the time
to chop and blend them manually. Mixer grinders can also be used for preparing the batter for dosas and idlis,
which are a staple in South Indian cuisine.
Overload Protection in Mixer Grinders
Overload Protection is a crucial feature in Mixer Grinders that prevents the motor from getting damaged due to
excessive load or overheating. It automatically shuts off the motor when it detects an overload, ensuring the lon-
gevity and durability of the appliance. This feature is especially useful when grinding tough ingredients or using
the mixer grinder for an extended period.
Benefits of Overload Protection in Mixer Grinders
Having an overload protection feature in your Mixer Grinder offers several advantages. It safeguards the motor
from burning out, saving you from costly repairs or replacements. It also enhances the overall lifespan of the ap-
pliance, ensuring reliable performance for years. With overload protection, you can confidently use your mixer
grinder without worrying about overheating or excessive strain on the motor, making it a valuable addition to your
kitchen appliances.
Electric Iron:

An electric iron is a household appliance used to remove creases or wrinkles of the clothes by the combination of
heat and pressure. After turning it on, a flat triangular soleplate is pressed on the clothes to make them smooth
and flat.

An electric iron is an application of heating effect of current. Current is taken from the power supply which heats
up the coil inside the iron, and this heat is then transferred to the soleplate due to the conduction, and when it’s
rubbed on clothes, small strings of clothes stretch to go flat.
An electric iron might not remove creases when it’s too cold, and cloth might burn when it’s too hot, so there is a
range of temperature in which an electric iron operates effectively. Domestic irons generally range in operating
temperature from between 250 °F (121 °C) to 360 °F (182 °C).
Working:
When a current is passed through the heating element which is placed between the sole plate and pressure plate,
the element gets heated up and transfers its heat to the sole plate through conduction and in-turn the sole plate
also gets heated up. Now to remove the wrinkles in clothing, we should apply heat and pressure. Heat is formed
due to the coil and when we press the clothes with iron, the wrinkles are removed. For maintaining the optimum
temperature, a thermostat is used along with pilot lamp which serves as an indicator.
Types of Electric clothes irons:

There are basically two types of an electric iron which are given below.
Automatic:
1 It’s thermostat switch to regulate the heat to a predetermined value. When the predetermined value of the
temperature is reached, the thermostat switch automatically disconnects the electricity supply and reconnects
the same when iron starts cooling down.
