The use of high-temperature fire to heat gas stoves is suitable for high-temperature cooking, such as blasting, and can increase the taste of vegetables. However, if it is not possible to select a stove, not only is there not enough firepower, but cooking is inefficient and the taste of the food is affected。
So, what are the details to be taken into account in selecting the many brands and models of gas stoves in the market? Let's go over it。
Basic parameters for gas stoves
1. Air source adaptation
The gas stove nozzle structure of different sources is different and not universal, and therefore attention needs to be paid to the type of gas source at home when selecting. Currently, the main domestic sources of gas are natural gas, liquefied petroleum gas and artificial gas, which require the selection of the corresponding stoves based on the domestic sources。
2. Rating heat flows
The rated heat flow of the gas stoves, also known as firepower, is mostly between 3. 8 and 5. 2 kw. The choice could be based on family cooking habits, such as those used to cook, and the choice of gas stoves around 4. 2 kw would be sufficient, while those who like to fire would be advised to choose 5. 2 kw。
Although the greater the fire, the better the fire experience, the household does not recommend the choice of gas stoves above 5. 2 kw, which are costly and easy to burn and are not suitable for daily household use。
3. Thermal efficiency
According to the national standard, 63 per cent of gas stoves are energy efficient and more energy efficient. Currently, many medium- and high-end gas stoves can reach 70 per cent or higher, and it is recommended that preference be given to such products。
Number of stove eyes
There are more domestic gas stoves and two stoves. It is recommended that preference be given to double stoves so that cooking can be more efficient by cooking on the one hand and stew on the other. During holidays, for example, multiple dishes can be produced at the same time, saving more time。
Ii. Association
Gas stoves can be divided into desktops, embedding and table embedding, depending on how they are installed。
1. Desktop gas stoves
They are cheaper and can be used directly on the table, without the need for specialized installation, suitable for users with low budget, temporary or small space. Desktop gas stoves occupy a larger amount of space and are difficult to clean, and households are not recommended for long-term use。
2. Embedded gas stoves
It's embedded directly into the surface and it enhances the overall beauty of the kitchen. And embedded gas stove surfaces are smooth, almost unsanitary and easy to clean. However, embedded gas stoves require openings on the stage, the overall cost of initial installation is higher and, if the stoves are replaced at a later stage, the size of the openings needs to be noted。
3 and 2 embedded gas stoves
Two types of installation, on or below the support stage, are used in practice, which usually chooses a more fixed mode. However, it is easier for a two-use embedded gas stove to choose the means of installation according to its needs than a desktop or embedded one。
Iii. Materials of gas stoves
1. Panel materials
Gas stove panels can be divided into stainless steel, steeled glass, ceramic panels, etc。
Stainless steel panels: have the advantage of shaving and heat tolerance, but are prone to oil contamination and more troublesome cleaning. The stainless steel panels are suitable for household use with a higher frequency of daily use and in pursuit of durability。
Steeled glass panels: have advantages such as coloured, cleanliness, but care needs to be taken to select blastproof glass with a 3c mark. In the process of use, care is taken to avoid the use of heavy objects to impact the panel or to make the panel cold and hot, which may lead to the break-up of the steel-coated glass panel。
Ceramic panels: appearance and impurity, between stainless steel and steel-coated glass panels, but with a low hardness, easy to scrape, relatively high prices and slightly lower utility。
2. Cookers and lid materials
As an important combustion component of the gas stoves, the first and the cover of the stoves, using copper or copper alloys, have the advantage of high temperature tolerance, corrosive resistance, and thermal fitness, and are the best materials. The second is other material alloys, which are slightly lower in price and have a good value for money. On the other hand, stoves and fire caps that use materials such as iron and cast iron are highly rusty and have a short useful life and, although cheap, do not refuel such gas stoves。
The second option is a stove and a firecap with disassembly structures that are easily cleaned on a daily basis。
3. Ignition
The main ones are electro-pulse ignition and voltage ceramic ignition。
The electro-pulse ignition is easier than simple, with a high hit rate, except for battery power。
The voltage ceramic ignition is more frequent in the cookers, and there is no need to use batteries for a single switch to fire. The success rate of the voltage ceramic ignition is related to the environmental humidity, which is not easily lit, and the speed of ignition is slower。
Iv. Safety performance
1. Fire suppression protection
Qualified gas stoves must be equipped with fire-closing protections, which can automatically cut off the gas source in case of accidental fire out and avoid gas leaks. Common gas stove shut-off protection units are mainly thermally sensitive, thermal and photovoltaic。
Heat-sensitive: using a two-metal piece structure with simple structure and low cost advantages. However, installation is difficult and has a short useful life。
Thermal voltage: composed of two components: thermal voltage and electromagnetic valves, which are made of different thermal voltages generated by different alloy materials in a function of temperature. Thermal voltage security protection is simple, convenient, low-cost and widely used. It is only this way that it is characterized by high heat inertity, slow reaction and short operational life。
Ion induction: also known as pv. When gas is used in combustion, the flame ion has a single-directive electrical feature, which reacts rapidly and has high safety advantages。
It is recommended that priority be given to thermal electromechanics and ion-sensor protections, which are relatively more secure。
Additional security features
High-end gas stoves have some nearby safety features. For example, child locking devices, dry burning techniques, etc., can avoid the danger of children being mis-operated or having a prolonged porridge to forget the fire。
V. Branding
The choice of well-known branded gas stoves is not only of guaranteed quality, but also of good after-sales service and more secure use locally。
The domestic market for gas stoves is dominated by national product brands such as boss, fang tai, american, washington, supor, creative commons, etc., which have a good reputation and are guaranteed after-sales services, which can be chosen from their own budgets。
Finally, recommendations such as openings, installation of gas stoves are handled by professionals and are used to ensure that they are well ventilated and that the pipes are well connected to avoid safety risks arising from inappropriate installation。
