What are the selection criteria for gas stoves?

Common sense of gas stove purchase, safety and environmental protection are the selection criteria.

Whether the gas stove is good or not, the key depends on the stove. The stove is known as the "heart of the stove". As the core component of the cooktop, the cost of the stove accounts for 1 3 of the total cost. The difference in the air intake mode of the stove is related to the safety, power and energy-saving performance of the cooker.

The air intake mode of the built-in gas stove is divided into two types: "upper air intake" and "incomplete upper air intake". One of the best ways to get air is "up to the air". At present, the Italian Sabaf is a professional manufacturer of "upward intake" stoves.

The expert commented: "The burner head in this way is reliable and safe – the glass panel will not be affected by tempering, it is highly clean, and it is also beneficial for maintaining a healthy atmosphere." However, its air intake is slightly smaller, and it is difficult for the furnace heat load to meet the high standards.

Experts also said that at present, most of the so-called "upward intake" type stoves in China are actually not really fully enclosed "upward intake".

Incomplete upper air intake includes: "side air intake", "rear air intake", "lower air intake", "three-dimensional air intake", etc., characterized by large firepower, and the size of the fire can be adjusted, can meet the needs of the Chinese people, the disadvantage is poor cleaning, especially the existence of potential safety hazards, there is a possibility of tempering resulting in tempered glass panel bursting.

The mainstream and direction of the development of built-in gas stoves should be completely upper air inlet burners, which has become the consensus of industry experts, mainly because of its good cleanliness, safety and environmental protection, and the representative stove head is Sabaf, Italy. However, the fire power of the built-in gas stove is generally small, the heat flow is generally only about about it, and the center fire is small and generally cannot be adjusted separately in use.

Safe, gas-saving, about some qualified products, as long as you choose some big brands, these are comprehensive.

The parameter selection of gas stove depends on the rated heat load, adjustment range, thermal efficiency, accessory function and material.

1. Rated heat load.

Of course, the maximum firepower of the gas stove is that the bigger the better, and the more vigorous the fire section, the better the taste of stir-frying. Generally speaking, the heat of the stew should not be less than; The heat of stir-frying should not be less than; The power of stir-frying should not be less than 4kw.

2. Adjustment range.

A good gas stove can not only produce a large fire, but also a small fire. Between the large fire and the small fire, is the adjustment range of the gas stove. The average fire knob can only be rotated 180°, while the adjustment range is wider than that of the well-known product, but it can be rotated 220° or more.

3. Thermal efficiency.

Under the same firepower, the higher the thermal efficiency of the product, the more gas-saving. Moreover, the thermal efficiency of a gas stove placed directly on the countertop is higher than that of a built-in one.

4. Attachment function.

Choose a gas stove with precise temperature control and timing, if you want to make a pot of soup, each stage of the feast needs to have different firepower, with precise temperature control and timing These two functions, you don't need to look at the stove often to make soup, it will be very convenient.

5. Material. The less likely the stove is to rust, the better the material with high temperature resistance, otherwise the rust will block the pores and fire holes, resulting in insufficient combustion and insufficient firepower. Copper, aluminum, cast iron.

Problems to pay attention to when buying a gas stove:

1. To understand whether there is a flame-out protection device, the stove with a flame-out protection device has a higher safety, and when the flame is extinguished by wind or water, the gas can be automatically cut off.

2. Look at the damper adjustment. When conducting the ignition test, you should also check whether the air control door of the gas stove is easy to adjust and whether the installation of the pot bracket is appropriate.

3. Look at the surface panel of the cooker, and the stainless steel panel is the best. The panel should have a certain thickness, and some cooker steel plates are thinner and easy to deform. The surface of some products made of cast iron, steel plate and other materials should be evenly painted without blistering or falling off.

4. Be clear about the type of gas used in your home, whether it is natural gas, artificial gas or liquefied petroleum gas. When purchasing, you should pay attention to the express indication on the box, which can also be identified by its model. For example, if the model number is JZ12T2-A, J stands for household, Z stands for stove, 2 stands for two-eye stove, T stands for natural gas, if the letter is R, it means artificial gas, and if it is Y, it stands for liquefied petroleum gas.

5. The installation position of the switch knob, nozzle and ignition device of the gas stove must be accurate, when ventilating and ignition, it should be ensured that the gas can be ignited every time it is ignited, and the flame should burn all the fire holes within 4 seconds after ignition.
