Household appliances are indispensable partners in our daily life, and their existence greatly improves the convenience and comfort of our lives. When shopping for home appliances, many people hold the principle of practicality first, believing that affordable products are enough to meet daily needs.
With the rapid iteration of technology, many home appliances will face the fate of being eliminated after several years of use, which seems to provide sufficient reasons for us to choose low-cost products.
I would like to remind you that for some home appliances, the excessive pursuit of low prices can cause a lot of problems. These low-priced products may be greatly compromised in terms of performance, user experience, and even safety, making us feel a lot of inconvenience and even annoyance during use.
1. Projector
In recent years, projectors have gradually become a new favorite in the home, especially among young people. With its small size and flexible mobility, the projector can bring us the enjoyment of watching movies on a large screen in different spaces.
When buying a projector, we can't just look at basic parameters such as price and picture quality. Low-priced projectors often have many performance deficiencies and hidden dangers.
Problems with low-priced projectors:
(1) The first picture quality is not good. Low-priced projectors may not be able to reach the resolution standard of HD or even 1080P, which leads to a great reduction in picture clarity when viewing, which affects the viewing experience.
(2) The viewing environment is demanding. Low-cost projectors usually suffer from low brightness and poor light resistance, which means that in a lighted environment, especially during the day or with the lights on, the projection picture will be severely disturbed and become blurry.
(3) The service life is short and noisy. Low-cost projectors often use traditional bulb light sources, which have a short service life and poor heat dissipation performance, and may lead to problems such as halving the brightness and increasing noise when used for a long time.
Purchase suggestion:
(1) More attention should be paid to its performance indicators such as the number of lumens, resolution and type of light source. For projectors used in the living room, it is recommended to choose a product with a lumen count of more than 1500ANSI to ensure clarity when viewing during the day.
(2) In terms of resolution, at least 1080P standards should be selected to meet the needs of high-definition image quality. In terms of light source type, it is recommended to choose LED light source or laser light source, which perform better in terms of service life and stability.
(3) When choosing a projector, we also need to make trade-offs and trade-offs according to our actual needs and budget.
2. Gas water heater
In the water heater market, gas water heaters and electric water heaters are the two mainstream products. Compared with electric water heaters, gas water heaters have the advantages of large water output, sufficient water supply and instant heating, so more and more families are choosing gas water heaters.
When buying a gas water heater, we can't just look at the price factor. Low-cost gas water heaters often have many performance defects.
Problems with low-priced gas water heaters:
(1) Insufficient effluent flow. Low-cost water heaters often have a small number of liters and cannot meet the needs of multiple water points at the same time, which can cause a lot of inconvenience during use.
(2) The water temperature is unstable. The constant temperature technology of low-cost gas water heaters is often poor, and most of them use simple proportional valves to adjust the temperature, which leads to large fluctuations in water temperature, which is prone to the phenomenon of hot and cold, which affects the bathing experience.
(3) Finally, the safety performance is low. Low-cost water heaters usually have a low level of safety protection, and may lack features such as anti-dry-burning, anti-freeze protection, and current overload, which increases the safety risk during use.
Purchase suggestion:
(1) It is recommended to choose a water heater with a moderate number of liters and a capacity increase function to meet the water demand of different scenarios. In terms of thermostatic technology, priority should be given to products with dual water vapor temperature control, which can accurately control the temperature difference within a small range and provide a better bathing experience.
(2) When choosing a water heater with zero cold water function, we need to fully consider our own needs, installation costs and usage costs.
(3) In terms of safety performance, we should choose products with a high level of protection and a variety of safety protection functions to ensure safety and worry-free during use.
3. Wall-mounted air conditioner
The place of air conditioning in modern home is self-evident, it brings us coolness in summer and warmth in winter. Among the many types of air conditioners, wall-mounted air conditioners have become the choice of many families because of their advantages such as affordable price, easy installation and simple structure.
When it comes to buying a wall-mounted air conditioner, we can't just look at the price and brand. In fact, air conditioners at different price points, even if they are of the same brand, may have significant differences in performance and user experience.
Problems with low prices:
(1) Low-priced wall-mounted air conditioners often have the problem of low refrigeration efficiency.
(2) Many low-cost air conditioners use the fixed-frequency technology that is about to be eliminated, which not only makes the refrigeration efficiency low, but also easily leads to a large indoor temperature difference, which affects the comfort.
(3) Low-cost air conditioners usually have a lower energy efficiency rating, which means that they consume more electricity during operation, increasing the burden of electricity on the household.
(4) The quality of the compressor of the low-cost air conditioner is often not guaranteed, which not only shortens the service life of the air conditioner, but also may produce large noise during use, which affects the quiet atmosphere of the home.
Purchase suggestion:
(1) We should pay more attention to the performance and energy efficiency level of products. It is recommended to choose an air conditioner with inverter technology, which can control the indoor temperature more accurately, reduce temperature fluctuations, and be more energy-efficient and quiet during use.
(2) In terms of energy efficiency grades, priority should be given to products with grade 1 or grade 2 energy efficiency to reduce operating costs. For the core component of the compressor, we should choose products from well-known brands with guaranteed quality.
4. Air-cooled refrigerator
In the refrigerator market, air-cooled refrigerators have gradually become the mainstream choice, while traditional direct-cooling refrigerators are gradually declining. This is due to the advanced refrigeration technology of air-cooled refrigerators, which not only effectively avoid the trouble of frost, but also perform well in terms of temperature equalization and precise temperature control. In addition, the variety of designs and large capacity are also the reasons why air-cooled refrigerators are popular.
Problems with air-cooled refrigerators:
(1) The preservation effect is not good. Many low-cost air-cooled refrigerators lack an independent greenhouse control room, which makes the ingredients easy to dry and dehydrate, affecting the taste and freshness of the food.
(2) Food is easy to carry over flavors. Most low-cost refrigerators use a single-cycle system, which makes it impossible to effectively isolate the odor of different foods when the cold air circulates between the refrigerator and the fresh-keeping room, resulting in cross-flavoring of food and affecting the overall food quality.
(3) High power consumption and high noise. The compressor and fan of low-cost refrigerators often use fixed-frequency technology, which not only makes the refrigerator consume more electricity during operation, but also produces loud noise, which affects the quiet environment of the home.
Purchase suggestion:
When purchasing an air-cooled refrigerator, we should pay more attention to the performance and quality of the product.
(1) Priority is given to cross-door or multi-door styles, which can provide more reasonable space utilization and better food preservation effect.
(2) You should choose a refrigerator with a dual-circulation or multi-circulation system, which can effectively solve the problem of cross-flavor between foods.
(3) In terms of energy saving and noise control, it is recommended to choose refrigerators equipped with inverter technology, especially products with dual inverter (compressor + fan), which perform well in energy saving and noise control.
brief summary
In short, when buying these four appliances – air-cooled refrigerators, wall-mounted air conditioners, gas water heaters, and projectors – we should abandon the idea of overly low prices and instead focus on performance, quality, and safety. Only in this way can we truly enjoy the convenience and comfort brought by these home appliances, so that every day of life is full of beautiful experiences.
