Description

High-power infrared horizontal heat radiation outdoor gas heater

Technical field

The invention relates to the technical field of outdoor heaters, in particular to a high-power infrared horizontal heat radiation outdoor gas heater.

Background technique

Most of the existing gas heaters use combustion gas to heat them. These outdoor gas heaters are characterized by high efficiency and cleanliness, and become the best tools for outdoor heating.

At present, the style and structure of outdoor heaters are various. The more common one is the umbrella gas heater, which uses a cylindrical burner with an umbrella-shaped radiation cover. The burner is produced by mixing gas and air. The flame acts as a heat source, and the hot air is pressed to the bottom through the umbrella cover to transfer heat to the surroundings. The advantage is that since the burner and the umbrella cover are disposed at a high position, the heating range is 360 degrees, but there are also disadvantages, and the disadvantage is that The heat is mainly transmitted in a convective manner, and the hot air itself moves upwards. Most of the heat is diffused into the atmosphere within a short distance from the bottom of the umbrella cover. Standing under the heater, the crowd will feel that the head is hot and the lower body is still cold, and the heat utilization rate is extremely low.

Technical solution

The present invention is directed to the above-mentioned deficiencies in the prior art, and provides a high-power infrared horizontal heat radiation outdoor gas heater, which is provided with an opening in the front panel of the box and an infrared gas burner at the opening, the infrared gas The burner is installed in a horizontally outward radiation direction, and can be directed and centrally heated to an area, and the infrared light can be actively absorbed by the human body, thereby improving heat utilization, reducing energy consumption, and reducing the use cost.

The technical solution of the present invention is implemented as follows:

A high-power infrared horizontal heat radiation outdoor gas heater comprises a box for placing a gas bottle, and an ignition control device is arranged on the box body, and a universal wheel is arranged at the bottom of the box body on the front panel of the box body An opening is provided, in which two or more infrared gas burners are relatively independent, and the infrared gas burner is installed in a horizontal outward radiation direction, and a metal mesh cover is installed outside the opening.

A plurality of vent holes are arranged on the gas equalization plate.

The infrared gas burner adopts the introduction of gas into the box body and burns inside the ceramic plate. Since the surface of the ceramic plate is covered with honeycomb small holes, the surface of the entire ceramic plate is fully burned after a short time to generate heat radiation infrared rays, and the temperature rises rapidly. The heat is high and there is no visible flame; the ceramic plate has a large area and many fire holes, and the surface of the hot ceramic plate can completely burn the gas and has superior wind resistance. The gas equalizing plate has a curved shape and is provided with a plurality of venting holes to ensure that the gas can uniformly fill the inside of the casing after entering.
