How to choose range hood and gas stove?

In the process of purchasing range hoods and gas stoves, we should pay attention to the following aspects:

1, exhaust air volume

The exhaust air volume of range hood refers to the exhaust air volume per unit time when the static pressure is zero. Generally speaking, the greater the air volume, the stronger the ability of the range hood to absorb and exhaust oil smoke. The country stipulates that the exhaust air volume of range hoods should be more than or equal to 7 cubic meters per minute, while the exhaust air volume of general range hoods can reach 13~ 15 cubic meters per minute.

2. Wind pressure

The wind pressure of range hood and gas stove refers to the static pressure when the air volume of range hood is 7 cubic meters per minute. The greater the wind pressure, the stronger the downward flow resistance of the range hood. Under the condition of long smoke exhaust pipe, products with large wind pressure value can ensure the complete exhaust of lampblack. The state stipulates that the wind pressure of range hoods should be greater than or equal to 80Pa.

3. Noise

The noise of range hoods and gas stoves in the kitchen often annoys many people who cook. Noise refers to the sound made by a range hood when it works normally at high speed at rated voltage and rated frequency. Noise is an important technical index to measure the performance of range hood. Obviously, the smaller the noise value of the range hood, the better. The national standard value does not exceed 74dB. The noise of the gas stove in the kitchen has been reduced.

4. Engine thrust

The suction of range hood and gas stove depends on the power of motor. Generally, the motor power on the market is between180-220 W. Relatively speaking, the greater the motor power, the better the smoking effect. But it doesn't mean that the greater the motor power, the better. This needs to take into account the size of kitchen fumes. If the oil smoke is not big, don't choose high power, otherwise it will waste electricity. ?

Pay special attention to the following points when buying:

1, logo: it includes two aspects-the logo of the range hood and the instruction manual. The range hood shall be marked with its model, manufacturer or distributor name, trademark, rated voltage, rated input power and certification mark. If the range hood has lighting bulbs, the maximum power of the bulbs used should also be marked on or near the lampholder. At the same time, each range hood is accompanied by a Chinese instruction manual to help consumers use it safely. The manual should indicate the minimum distance between the range hood and the supporting surface of the cooker, and it is forbidden to bake the range hood directly with fire.

2. Structure: In the structural design of the range hood, it should be considered that it is convenient to effectively remove accumulated grease and dirt, and the surface of the shell should be as smooth and flat as possible. Usually the range hood needs to be fixed on the wall, so in addition to keys, holes, hooks and so on. It also requires a suitable device to fix it on the wall, and this device should be made of metal that is not easy to move or deform.

3. Consumers should choose a suitable range hood according to the size of their kitchen and the amount of lampblack. European-style lampblack machine has beautiful appearance and fine manufacturing technology, but there is no large-capacity lampblack machine, which is suitable for modern kitchens with large space and little lampblack. Deep range hood has beautiful appearance. Compared with other range hoods, they generally have the advantage of large air volume. Moreover, the structure of the large-capacity smoke collection hood is beneficial to absorbing and discharging oil fume, and is suitable for kitchens with more oil fume and larger space. Thin range hood is light and beautiful, occupies small space and is suitable for small kitchens. Sub-deep range hood is between thin range hood and deep range hood, which is suitable for kitchens with moderate space and large lampblack.

4. Choose producers and operators with good after-sales service. Under normal circumstances, you should buy a well-known brand of range hood. These enterprises have high-quality service team, advanced production technology and production capacity, which can not only produce high-quality range hoods, but also provide high-quality after-sales service to relieve the worries in the use of range hoods.

5. Consumers should choose range hood products according to their consumption ability. When buying, they can feel whether there is air leakage around the range hood and whether the air volume is large. If there is no air leakage and the air volume is large, it shows that the range hood has strong oil absorption ability; You can also directly feel the noise of the range hood, especially the front noise, and touch the shell to see if it vibrates. Quiet and stable range hood is the first choice for users.

Gas stove:

1. Gas cookers require extremely high safety performance. You must buy products from professional manufacturers with large production scale, such as Vantage's cooker products, to ensure that the self-produced rate of spare parts can reach over 99%.

2. Igniter is the most critical component in the ignition system of table gas stove. The igniter with strong ignition and crisp sound ensures the success rate and service life of the furnace. At present, Vantage's new energy-saving stove has realized the combination of igniter and flameout protection device, which is safer.

3. Burner and distributor are the most critical components in the combustion system of table gas stove. Rust-proof burner and forged copper distributor ensure the thermal efficiency of combustion and long service life, while the alloy honeycomb of Vantage energy gathering furnace uses alloy material, which excites high-energy light waves equivalent to 60% of gas efficiency at the high temperature of 860℃, and forms double heating with the flame.

4. The appearance of the gas stove should be beautiful and generous, and there should be no collision around the body. The surface of some products made of cast iron, steel plate and other materials should be painted evenly and smoothly, without foaming or falling off. The overall structure of the gas stove should be stable and reliable, the stove surface should be smooth and flat, without obvious warping, and all parts should be firmly installed without looseness.

5. The installation position of the switch knob, nozzle and ignition device of the gas stove must be accurate. When the gas is ignited by ventilation, the gas should be basically ignited every time (it should be started at least 8 times for 10 to ignite the flame), and the flame should burn all the fire holes within 4 seconds after ignition. When the electronic igniter is used for ignition, there should be no electric shock when the human body touches the metal part of the cooker. When the flame burns, it should be uniform, stable and blue, without yellow fire and red fire. Maybe you will ask: Why did the shaped charge furnace first become popular in Lanhuo? In fact, it is the infrared heating generated by the alloy honeycomb burner at high temperature, not the "red fire".

6. During the ignition test, you should also check whether the throttle of the gas stove is easy to adjust and whether the pot bracket is installed correctly.
