There are many electrical appliances in life, which can greatly facilitate our life and improve our quality of life. However, electrical appliances are being replaced too quickly, and some electrical appliances that were once "all the rage" are now rare.
Today, I will take stock of 5 kinds of electrical appliances that used to be hot, but now they suddenly "fell off the altar". When I learned the truth, I couldn't help but sigh: it was really "not wronged".
1. Zero cold water gas water heater
What is a zero-cold gas water heater? It is a water heater that immediately has cold water as soon as the faucet is turned on. Traditional water heaters need to clean the cold water in the pipes before they can use hot water.
The advantage of a zero-chilled gas water heater is that there is no need to drain the cold water and there is no need to wait. This is especially true when the distance between the ends of water is long, and when you wash your face in the morning. The face has been washed, and the cold water has not been washed. If you have zero cold water, you won't have this trouble.
However, there are also quite a few disadvantages to the "zero cold water heater".
The energy consumption and cost are high, and if the distance between the ends of the water is long, it will be a big consumption.
It is difficult to install and maintain, and it is necessary to install a waterway circulation, which will not only increase the installation cost, but also make maintenance more difficult.
It affects the water quality, because if the hot water is kept circulating for a long time, it is easy to cause the precipitation of minerals and impurities in the water, which is easy to have a certain impact on the water quality.
The price is relatively high, and it is much more expensive than ordinary gas water heaters.
In order to save waiting time, but also to save some cold water, let the whole waterway circulate. However, it is necessary to increase the cost of buying water heaters, the cost of installing plumbing, and the high cost of gas. For the average family, it is really not cost-effective.
Second, the electronic cat's eye
Compared with the traditional mechanical peephole, the electronic peephole has a wider viewing range and higher definition, and can also be remotely monitored through the Internet. In addition, the electronic cat's eye is stronger and not easy to remove, so naturally there is no need to worry about being used by criminals to unlock the lock with a hook.
However, in recent years, smart locks with cameras have become more and more popular, and their prices have become lower and lower. The function of the electronic peephole has been included in the smart lock, and it has also added functions such as face recognition unlocking and hovering automatic photography.
If a smart lock is installed, the electronic peephole becomes a redundant ornament. Naturally, it was slowly eliminated.
3. Sink dishwasher
What is a sink dishwasher? It is installed on the countertop like a sink, and its biggest selling point is that it is easy to install. In contrast to built-in dishwashers, sink dishwashers can be replaced without cutting the countertop.
However, there are quite a few disadvantages of sink dishwashers.
The capacity is limited, and the relatively large utensils can't be put in, let alone pots.
The washing effect is mediocre because the sink dishwasher only has a washing spray arm at the bottom and not at the top, so it cannot wash the dishes adequately.
Occupies a sink space, and installing it next to the sink will take up the area of the sink.
The price is relatively high, and for families with a limited budget, the cost performance is really a bit low.
Comparatively speaking, built-in dishwashers are simply a whole bunch of advantages. As a result, sink dishwashers are slowly becoming obsolete, and built-in dishwashers are the first choice.
4. Automatic stir-fry machine
I found that the automatic stir-fry machine is simply an invention of "taking off your pants and farting". It just does the simplest stir-fry in cooking, and the most tedious steps such as washing and preparing vegetables are not missing.
The reason why many people are too lazy to cook by themselves is because of the links such as choosing vegetables, washing vegetables, cutting vegetables, and cleaning up. Comparatively speaking, the stir-fry process is not very time-consuming and laborious.
For many people, the process of stir-frying is the most healing. Watching yourself turn your ingredients into a dish is a rewarding experience.
The most important thing is that the dishes fried in the stir-fry machine are not very delicious, and they can only be said to be average, and they cannot be compared with the skillful initial at all.
To put it mildly, it is to spend a lot of money and buy a "blender" to go home. Moreover, it does the coolest stir-fry part, making cooking more boring.
5. Household air conditioning fan
Because the price of air conditioning is too expensive, and there are also problems such as installation space that need to be considered. And the gimmick of the air conditioner fan is that it is cheap, saves electricity, and does not need to be installed. However, when I really started, I found that it was 108,000 miles away from what I imagined.
There is no refrigeration effect, it is in the form of water cooling + ice crystal box, to blow out cold air, and the effect is a little cooler than an electric fan.
It's very troublesome, and if you don't add an ice crystal box, it's even worse than an electric fan. You need to take the ice crystal box to the refrigerator to freeze, and you also need to change the water regularly, otherwise the water quality will be very dirty.
It consumes a lot of electricity, and compared with air conditioners, it is indeed more energy-efficient, but it is also much larger than ordinary electric fans.
Moreover, it is not silent at all, and there will be a lot of noise at night, which makes people unable to sleep.
Summary at the end of the article
The above 5 kinds of electrical appliances have a lot of problems, and they have been gradually eliminated by the market, so it is best not to pay IQ tax.
