Like all other technological devices, washing machines took many forms until they took their current form. After the machines, the first examples of which were wooden, the ones with the drying feature and then the fully automatic washing machines entered our homes.
The washing machines we use today are equipped with many technologies. These appliances, which have made great progress in terms of design, are equipped with higher capacities, many different washing programs and smart technologies that we can even control from the phone.
Even though all these features are improving day by day, there is one design concept that most machines have in common: Covers. The glass doors of almost all washing machines are always made inwards, ie ‘concave’. Have you ever thought about why?
There are two reasons why glass doors of washing machines are designed concave:
More efficient operation of the rotation mechanism inside the machine
The first reason for this design approach; to prevent the laundry from getting caught in the door part. The more the laundry moves and the more it spins, the better the washing will be, as its contact with water will increase. The fact that the glass extends inwards ensures that the laundry is pushed into this constantly rotating mechanism and thus it is washed better. If the door was flat, laundry could accumulate around the door and get stuck.
To prevent water leaks and protect the cap rubber
The tires surrounding the hole in the machines actually undertake a very important task. Even though these tires are produced to withstand high pressure, too much laundry in the machine and unbalanced rotation movements of the machine can cause them to tear. If it is torn, problems such as water leakage to the electronic parts of the machine and short circuit may occur.
The concave design of the cover glass also prevents the clothes from staying away from the cover rubber and its abrasion, in other words, possible water leakage is prevented.
