Description

Commercial Energy Saving Cookers

technical field

The utility model relates to a combustion appliance, in particular to the field of manufacturing commercial energy-saving gas stoves.

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: one, the thermal energy utilization rate of gas is low; two, the firepower distribution is uneven, only concentrated at the gas injection holes of the annular chamber, which is not suitable for commercial occasions such as restaurants and large restaurants. Be applicable.

Utility model content

The purpose of the utility model is to provide a commercial energy-saving cooker with high combustion heat efficiency, uniform firepower distribution and suitable for commercial use.

The purpose of this new model is achieved as follows: a commercial energy-saving cooker, including a cooker frame, a cooker head, and an igniter. The cooker stand structure is: the panel is fixed on four legs, and an opening is arranged on the panel; The upper opening of the cylinder is provided with a concave ceramic combustion infrared plate, which is in the shape of an inverted cone, and the entire infrared plate is evenly distributed with gas injection holes, and the radiation net is covered on the upper opening of the cylinder body, and Another inner cylinder with a smaller diameter on the coaxial line of the cylinder divides the chamber between the infrared board and the cylinder into an outer combustion chamber and an inner combustion chamber, and the outer combustion chamber and the inner combustion chamber are respectively A trumpet-shaped pipe for introducing gas is provided: two gas nozzles are respectively arranged at the openings at the large ends of the two trumpet-shaped pipes.

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

1. Energy saving, gas saving and environmental protection

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 suppress the precipitation of CO, CH, NOx and other harmful gases, 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.

Detailed ways

Figures 6 and 7 show that the new model includes a cooker rack 1, a cooker head 2, and an igniter. The cooker rack 1 has a structure as follows: the panel is fixed on four legs 1a, an opening is arranged on the panel, and a side vertical plate 1b is provided at the rear of the panel. ; Referring to Figures 2 to 5, the structure of the stove head 2 is: the upper opening of the cylindrical body 2b is provided with a concave ceramic burning infrared ray board 2c, the shape of the infrared ray board is an inverted cone shape, and the entire infrared ray board is evenly distributed with gas Spray holes, radiation net 2d cover on the upper opening of the cylinder 2b, another smaller diameter inner cylinder 2e coaxial with the cylinder 2b, the chamber between the infrared plate and the cylinder 2b The chamber separates the outer circular combustion chamber and the inner circular combustion chamber, and the outer circular combustion chamber and the inner circular combustion chamber are respectively provided with trumpet-shaped pipes 2f and 2h for introducing gas: two gas nozzles 2g and 2i are respectively arranged on the two trumpet-shaped pipes 2f, 2h at the big end opening.

The radiant net is conducive to uniform heat distribution and more complete combustion. The diameter of the inner cylindrical body 2e is equal to the diameter of the inverted frustum-shaped bottom plate of the ceramic combustion infrared ray plate 2c. The inverted frustum-shaped side plate of the ceramic combustion infrared plate 2c is formed by assembling and bonding a plurality of isosceles trapezoidal plates ( FIG. 5 ). Referring to Fig. 4, two trumpet-shaped pipes 2f, 2h of the inner circle combustion chamber and the outer circle combustion chamber are respectively arranged on the tangential direction of its circular combustion chamber, and the flow directions of the two air intakes are opposite; the two trumpet-shaped pipes 2f , 2h is also provided with an air inlet near the big end. That is, the mixed gas of gas and air enters the combustion chamber along the tangential direction after being introduced from the horn-shaped tube, and the flow direction of the mixed gas in the two concentric circular combustion chambers is opposite, for example, one clockwise and the other counterclockwise (viewed from the top view) .

Referring to Fig. 7, gas supply pipelines are installed on the stove frame 1: gas valves 2k and 2l are respectively installed on the two branch pipes of the gas main pipe 2j (Fig. 6), and then connected to the air inlets of the two gas nozzles 2g and 2i . Rather, the inner side of the pipe wall of the straight pipe portion is in this tangential direction. It can also be said that the intake air of the bell-shaped tube enters the circular combustion chamber along the tangential direction. The upper part of the cylindrical body 2b is also welded with a middle opening, which is used as a rectangular panel 2a fixed on the stove rack 1 . The electronic igniter can be arranged at the airflow inlet of the bell-shaped tube, and can also be arranged at the position above or below the ceramic combustion infrared plate. The gas branch pipes are all made of copper pipes, one is not rusty, and the other is easy to bend.

The cylinder 2b, the inner cylinder 2e, the two horn-shaped tubes 2h, 2f and the rectangular panel 2a of the stove 2 are all made of steel plates, and the surface is covered with a layer of enamel.

The two trumpet-shaped pipes 2h and 2f are preferably double-headed trumpet-shaped pipes, that is, both the air inlet and the air outlet are large-end openings, and the middle diameter is relatively small.

Existing commercial cooking ranges use ignition guns to ignite, but the present invention uses an electronic igniter (arranged above the ceramic burning infrared ray board) to ignite.

The stove frame 1 is provided with a protective vertical plate 1b, and the bottom of the stove frame 1 has four legs 1a.
