How to choose a gas hob?

Gas stove is a kitchen appliance that people often use.A high-quality gas stove can greatly improve cooking efficiency, let us enjoy cooking time!Poor quality gas stove not only inefficient cooking, but also easy to make kitchen utensils black.Therefore, it is important to choose a gas stove for our kitchen.How to choose a good gas stove?I want to share some skills with you!

A good gas stove must have the following characteristics:

High firepower, convenient ignition, safe, burner rust prevention, easy to clean.

Below, I will tell you how to choose a good gas stove for these five characteristics.

First of all, fire.

In the store, many guides tell you that "the heat load of the gas stove is mostly between 3.8kw-5kw, the higher the heat load, the greater the firepower, and often choose more than 4kw when stir-frying", which is correct, but one-sided.

In addition to thermal load, we also need to pay attention to energy efficiency levels!

Because the energy efficiency level is related to thermal efficiency, if the thermal load is also 4KW, the higher the thermal efficiency, the greater the firepower, the more energy-saving.

When purchasing, the high heat load and high energy efficiency level are the real big firepower.

Second, choose a good igniter.

At present, there are two main types of ignition devices on the market: electronic pulse ignition device and piezoelectric ignition device.

At present, most gas stoves are equipped with pulse ignition.Piezoelectric ignition has been phased out.

When purchasing, pay attention to whether the gas stove is ordinary pulse ignition or automatic pulse ignition!

Ordinary pulse ignition requires a period of time after pressing the knob to successfully ignite.Even if you see a fire and let go halfway, the ignition will still fail.

There is no need to press the knob after automatic pulse ignition operation.The pulse continued to ignite.A few seconds later, the automatic ignition was successful.

Therefore, automatic pulse ignition is better than ordinary pulse ignition.

Next, let's talk about safety devices.

The safety of the gas stove depends on whether the gas source can be cut off in time after the ignition is turned off.This is what we call a safety device.

The national standard for household gas cookers stipulates that since January 1, 2009, gas cookers without safety devices shall not be sold.

So we don't need to worry about safety devices, we need to think about which one to choose.

There are two types of safety devices on the market: thermocouples and ion sensing.

Thermocouple Safety Device:

The gas source is cut off by the temperature difference detected by the thermocouple.Some manufacturers can make it cut off the air source in about 10-20 seconds.Thermocouples do not need electricity.Therefore, most manufacturers use this method, which is low cost and mature application.

Ion Induction Safety Device:

The gas source can be cut off by sensing flame ions.In theory, the air source can be cut off within 0.5 seconds.Due to excessive sensitivity (when the flame shakes the air source will also be cut off), the manufacturer made a delay of 4-6 seconds, when the flame accidentally extinguished 6 seconds can be cut off.At present, only a few manufacturers use this method.Ion induction requires power consumption, and the frequency of battery replacement will be relatively high.

Therefore, many users will choose thermocouple safety devices for their own gas stoves.

In addition, we also have to consider the problem of combustion rust.

The main problem with burner rust is the material.

Burner mainly has cast iron base copper cover, aluminum base copper cover, all copper burner three kinds.

First of all, an all-copper burner is the best because copper conducts heat quickly and is not easy to oxidize and rust, but it is expensive.At present, there are relatively few models of all-copper burners on the market.

The difference between cast iron base and aluminum alloy base is temperature resistance.Cast iron has good temperature resistance, but it is easy to rust; aluminum alloy has poor temperature resistance, but it is not easy to rust.

Why are some models of the same base more expensive?The difference is the copper content of the copper cap.Some are all copper covers, some are copper alloy covers.All-copper is definitely better, but the price will be higher.It depends on individual needs.

Finally, cleaning.

Cleaning mainly involves the selection of panels.

At present, the gas stove panel has three kinds of stainless steel, tempered glass and ceramics.Stainless steel is resistant to high temperature and corrosion, but it is not easy to clean.Tempered glass is easy to clean, but the temperature resistance is not as good as stainless steel.Ceramic panels are resistant to high temperatures and easy to clean.But its price is higher, so there are few ceramic panel gas stoves on the market.There are mainly stainless steel gas cookers and tempered glass gas cookers on the market.A small budget is recommended to buy stainless steel, and a sufficient budget is recommended to buy tempered glass.

These are some tips for buying a gas stove more than that.We hope to help you choose the right gas stove for you.Thank you.
