Description

Commercial infrared high-efficiency energy-saving cooker

technical field

The utility model relates to a cooker, in particular to the technical field of a commercial energy-saving infrared gas cooker.

Background technique

The existing household gas cooker for kitchen is mainly composed of a burner and a hob. The burner is usually made of cast iron. The gas and air are introduced into the annular chamber through the gas inlet pipe and the air inlet pipe to mix, and then ignited by the igniter for combustion. , the combustion gas is sprayed out through the holes on the annular chamber to complete the heating operation. It has the following disadvantages and deficiencies: first, the thermal energy utilization rate of the gas is low; second, the distribution is uneven and only concentrated at the gas injection holes of the annular chamber.

Existing household gas stoves are not suitable for commercial occasions such as restaurants and restaurants. Existing commercial stoves often use a blower to blow air to assist combustion when burning and heating, which has the disadvantages of outdoor power consumption and high noise, and also has the problem of low utilization rate of gas heat energy.

Utility model content

The purpose of the utility model is to provide a commercial infrared high-efficiency energy-saving cooker with high utilization rate of gas heat energy and uniform firepower distribution.

The purpose of this new model is achieved as follows: a commercial infrared high-efficiency energy-saving cooker is composed of a cooker frame and a cooker head. The combustion plate is enclosed to form three combustion chambers, and the first, second, and third horn-shaped tubes communicating with them are respectively arranged on the three combustion chambers from the outside to the inside, and the air inlets of the three horn-shaped tubes are respectively provided with Gas nozzles, radiant nets are set above the infrared combustion plate.

Compared with the prior art, the beneficial effects of the present invention are:

1. Energy saving, gas saving, environmental protection, gas saving up to 50%

The novel technical point, one, adopts ceramic burning infrared ray plate (being infrared ray burning plate), and its shape is inverted cone shape, has more than 10,000 fire holes on it. When the flame is burning, the flame is converted into infrared rays to speed up the heating process of the object. Due to the transmission of infrared radiation, the performance of the gas stove is greatly improved; secondly, the inner cavity of the stove head is divided into two concentric chambers, and each chamber is introduced with gas and air by a trumpet-shaped drainage tube. This special internal structure using aerodynamic technology promotes the turbine-type rotation of the gas after entering the combustion chamber of the stove, so that the gas can be more fully pre-mixed, and the mixed gas is evenly distributed to more than 10,000 fire holes, and the gas is guided through the fire holes. The flow spiral overflows, and continuously delivers the mixed gas required for combustion to each fire hole, and enhances the adhesion of the mixed gas to the fire hole after the spiral overflows the fire hole, so that the gas is adsorbed on the surface of the combustion plate for full combustion. Effectively inhibit the precipitation of harmful gases such as CO, CH, NO×, and the powerful heat flow converts heat energy into flameless infrared radiation transfer, making the most effective and full use of the heat flow generated by gas combustion, greatly reducing the physical The loss of heat flow can save gas up to 40-48%.

2. It is specially designed for commercial use, and no longer uses a blower to blow air in for combustion. It has the functions of stable combustion, no noise, and energy saving.

3. The stove head is made of steel plate covered with a layer of enamel material. The burner has a service life of up to 10 years and is durable.

4. Specially designed air intake volume control mechanism, rotating the cover can make the air inlet on the cover cover and the air inlet hole at the front end of the horn-shaped tube (except for the nozzle mounting plate) from completely overlapping (that is, fully open) to gradually closing the air inlet wind hole. On the one hand, the air is taken in from the air inlet of the cover, and on the other hand, the air is taken in from the air inlet on the side of the horn-shaped tube, so that the amount of air intake can be easily controlled according to the combustion situation, so that the combustion effect reaches the best.

5. The stove adopts three concentric combustion chambers, and each combustion chamber takes in air (mixed gas) from its tangential direction, and the flow direction of the gas in the three combustion chambers from the inside to the outside is sequentially opposite, which helps Due to the full cooperation of gas and air, full and complete combustion is finally achieved.

Detailed ways

Figure 1, Figure 2, Figure 3 and Figure 4 show that the new model is composed of a cooker frame 11 and a cooker head. The cooker head structure is: three cylinders located at the same center with an opening at the top, and an inner concave infrared burning plate 27 with an isosceles trapezoidal cross section. Enclosed to form three combustion chambers, the three combustion chambers are respectively provided with first, second and third horn-shaped tubes 21, 22, 23 communicating with them from the outside to the inside. The three horn-shaped tubes 21, 22, Gas nozzles 24, 25, 26 are respectively arranged on the air inlet of 23, and the radiation net 28 is arranged on the infrared combustion plate 27 tops. The first, second, and third horn-shaped pipes 21, 22, and 23 are all arranged along the tangential direction of their corresponding combustion chambers, and the airflow directions of the first horn-shaped pipe 21 and the second horn-shaped pipe 22 are opposite, and the second horn-shaped pipe 21 The airflow direction of the tube 22 is opposite to that of the third flared tube 23 . Air intake holes 30 are evenly distributed on the first, second and third trumpet-shaped tubes.
