The problem of the drum rotating while lying down has been fixed, so the washing machine is full of inefficiency. The drum washing machine is pretty, but think carefully before buying it. Hello, everyone. This is Fun Science. After disassembling and cleaning a regular washing machine and a drum washing machine for a month, the pros and cons of the two types of washing machines have been clearly organized, so I would like to share my thoughts on the drum washing machine with you. The general comparison between a drum washing machine and a drum washing machine is like this, but Fun Science will only look at it from a technical perspective. We think that a drum washing machine is convenient because it has a front-loading method with the door in the front, and it has a pretty design, so it seems like a washing machine with the latest technology. On the other hand, a regular washing machine feels like an old model that has gone out of style. Technically, a regular washing machine is the basic method, and a drum washing machine is a derivative of a regular washing machine that has a drum lying down to put in and take out laundry from the front, and it is not an advanced method that is different from the previous generation. From now on, I will tell you why Fun Science does not recommend a drum washing machine. This video was created based on my personal experience, so please refer to it when purchasing and using it. 1. The drum washing machine weighs 100 kg, which is twice as much as a regular washing machine. A regular washing machine weighs 50 kg, while a drum washing machine usually weighs 100 kg. The main reason drum washing machines are heavy is because of the weight and frame. (Weight) Drum washing machines have a problem because they lay the heavy drum on its side and spin it with water. Various parts are added to solve this problem, so the structure is complicated and heavy. A regular washing machine has a motor on the bottom, but a drum washing machine has a motor that is overwhelmingly larger and heavier than a regular washing machine motor, so the center of gravity is shifted to the back. Therefore, the back is heavy and the front is light, so you need to put a weight on the front to balance the front and back so that the drum does not wobble as it spins. The yellow lump of metal you see on the screen is a weight, and it weighs 9 kg. This is a part that regular washing machines do not have. (Frame) And the washing machine frame needs to be strong to hang the lying drum and weight in the middle of the washing machine, so it is heavy. A strong frame and thick iron plate are required because a spring is attached to the frame to pull the washing tub and the 9 kg weight, and a shock absorber is required to support it from below, which leads to an increase in weight. A drum washing machine with a stainless steel dryer is that much heavier. If you tap the iron plate on the outside of the washing machine, the drum washing machine has a thick iron plate so it makes a dull sound, while a regular washing machine has a thin iron plate so it sounds like tapping a tin plate. This is the only way to prevent the up, down, left, and right movement of the washing tub as it rotates, so the drum washing machine is bound to be heavier. A regular washing machine has its parts concentrated at the bottom, so the load is on the floor, making it stable, sturdy, and natural like a top, but a drum washing machine is supported in the air, so it is not sturdy and its durability is low. 2. It is expensive. If it weighs twice as much because it has a lot of parts, it is normal for the price to be higher. Samsung mainly produces washer-dryer sets, so it is difficult to compare, but if you compare the 15kg LG washing machine, the regular washing machine (TR15MK) costs 451,600 won and the drum washing machine costs 651,960 won (T15WUA). The drum washing machine is 45% more expensive than the regular washing machine. 3. The washing performance is half. The regular washing machine uses a chemical reaction where the surfactant removes contaminants from the fabric while the washing drum is full of water, and the centrifugal force and strong water currents wash, so the washing power is excellent, but the drum washing machine washes by the drop of the laundry falling inside the rotating drum, so the power is weak, so the washing power is low, and if there is a lot of laundry or a large comforter, the washing does not take place well because there is no drop. For the drum washing machine, the laundry must be filled only halfway into the washing drum to create a drop and wash. You should not cram it in just because it is putting in. 4. It is difficult to clean. Since the motor of a regular washing machine is located at the bottom, you can disassemble it from top to bottom without taking the washing machine out, so you can disassemble it and clean it on the spot. However, since the bolts on the motor of a drum washing machine must be loosened at
