Description

Technical Field

[0001] The utility model relates to the technical field of combustion equipment, in particular to an infrared built-in burner. Background Art

[0002] Infrared cooktops utilize these characteristics of infrared radiation, achieving energy savings of over 40%. Infrared radiation panels, made of special refractory materials, convert the flame into infrared radiation, accelerating the heating process. This conversion of combustion heat into infrared radiation significantly improves gas stove performance.

[0003] In existing infrared burners, the ignition needle is usually placed inside the burner. During the combustion process, it is easily corroded by the combustion gas. At the same time, the needle tip of the ignition needle is exposed to the inner wall of the burner, resulting in a technical problem of a low service life of the ignition needle.

[0004] Therefore, improvements need to be made to this. Utility Model Content

In addition, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly indicating the number of the technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the present application, "several" or "multiple" means two or more, unless otherwise specifically defined. In this application, unless otherwise expressly specified or limited, terms such as "mounted," "connected," "connect," and "fixed" should be interpreted broadly. For example, they can refer to fixed, removable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediate medium; or internal communication between two components. A person skilled in the art will understand the specific meanings of these terms in this application based on the specific circumstances. In this application, unless otherwise expressly specified or limited, a first feature being "above" or "below" a second feature may include the first and second features being in direct contact, or the first and second features being in contact through another feature between them.

[0025] like Figure 1-4 As shown, an infrared built-in burner 1 is provided, comprising: a burner 1, wherein a furnace tube 2 is provided on the burner 1, wherein the furnace tube 2 is communicated with the burner 1, and at least a portion of the bottom of the burner 1 is recessed inward to form a receiving portion 3; a ceramic sheet 4, wherein the ceramic sheet 4 is built into the burner 1; a piezoelectric ceramic ignition needle 5, wherein the main body of the piezoelectric ceramic ignition needle 5 is installed in the receiving portion 3, and the needle head of the piezoelectric ceramic ignition needle 5 is placed at the position of the ceramic sheet 4; and an air intake pipe 6, wherein the air intake pipe 6 is connected to the burner 1 and is used for conveying gas.

[0026] In view of the technical problems described in the background art, an infrared built-in burner 1 is provided, which is a stove that can be used indoors or outdoors.

[0027] In the above technical solution, the accommodating portion 3 can be designed according to the size of the piezoelectric ceramic ignition needle 5, so that the piezoelectric ceramic ignition needle 5 is embedded in the accommodating portion 3. Since the main body of the piezoelectric ceramic ignition needle 5 is located outside the furnace head 1, it can prevent the combustion gas in the furnace from corroding the main body of the piezoelectric ceramic ignition needle 5. A ceramic sheet 4 is provided in the furnace and on the upper part of the piezoelectric ceramic ignition needle 5. The ceramic sheet 4 has a honeycomb-shaped or uniformly circular hole-shaped through hole, so that the needle tip of the piezoelectric ceramic ignition needle 5 can pass through the ceramic sheet 4 and be attached to the ceramic sheet 4, which can prevent the needle tip of the piezoelectric ceramic ignition needle 5 from being exposed to the combustion gas in the furnace.

[0028] like Figure 3 As shown, the burner includes a decorative cover 7, which surrounds the upper circumference of the burner head 1. The decorative cover 7 is made of metal. Preferably, the radial distance between the tip of the piezoelectric ceramic ignition needle 5 and the decorative cover 7 is 4 mm to 6 mm. At any position within this radial distance, an effective spark will be generated, instantly igniting the honeycomb ceramic sheet 4.

[0029] Specifically, it includes an air damper 8 , which is arranged at one end of the furnace tube 2 away from the furnace head 1 , and the air damper 8 can regulate the oxygen entering the furnace tube 2 .

[0030] refer to Figure 3 As shown, the stove includes a diverter plate 9, which is placed in the middle of the burner head 1 and has evenly spaced through holes. The diverter plate 9 has evenly spaced through holes in a semicircular area away from the furnace tube 2. The diverter plate 9 can ensure more uniform and complete combustion of the combustion gas in the burner head 1, prevent backfire, and make the stove safer to use.

[0031] refer to Figure 1 As shown, the air intake pipe 6 includes a first branch pipe and a second branch pipe connected to the first branch pipe. The first branch pipe passes through the furnace tube 2 and is placed in the furnace head 1. The second branch pipe is connected to the furnace head 1.

[0032] In practice, a secondary air intake system is employed. During operation, a first branch pipe and a second branch pipe deliver gas separately. The first branch pipe passes through the furnace tube 2 and is placed within the burner head 1. Preferably, an air inlet is provided at the bottom of the burner head 1, with the second branch pipe connected to the air inlet. This secondary air intake system ensures more uniform combustion.

[0033] The above does not limit the technical scope of the present invention. Any modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
