Abstract

The utility model relates to an oven device which comprises an infrared furnace end with an intake pipe, an igniter and a reducing valve. The oven device is characterized in that: the igniter comprises a gas valve which is internally cut with a fuel gas channel and a spitfire tube; wherein, the intake end of the fuel gas channel is connected with the reducing valve while the outlet end (a nozzle) of the fuel gas channel is connected with the intake pipe of the infrared furnace end; one end of the spitfire tube is communicated with the fuel gas channel; the other end (a spitfire mouth) of the spitfire tube is as high as or slightly higher than the furnace face of the infrared furnace end. After the fuel gas enters the fuel gas channel of the gas valve from the reducing valve, most of the fuel gas enters the furnace end through the nozzle, while a fraction of the fuel gas enters the spitfire tube; the fuel gas in the spitfire tube begins to burn after being ignited, and the flame is spurted to the upper side of the infrared furnace end through the spitfire mouth, which can directly lead the flame to the infrared furnace end. Therefore, the furnace end does not need any change; more particularly, the oven device can swiftly and conveniently light a fire dispensing with a fire-leading nick.

Description

an oven device

technical field

The utility model relates to an oven, in particular to a portable oven device which is easy to ignite.

Background technique

At present, barbecue food is more and more popular among consumers, and there are more and more barbecue activities. People usually use portable ovens suitable for home use and outings as barbecue tools, which are light and affordable; and because infrared burners save gas and have high firepower, barbecues are hygienic, convenient, and have good barbecue effects, so portable ovens are usually equipped with Infrared burner. As shown in Figure 4, the infrared burners currently on the market usually use an electrode-type ignition device 1 to ignite, and the electrode-type ignition device 1 is arranged on the infrared burner. The ignition device, the electrode must be close to the burner head plate, so a gap 2 has to be opened on the protective net of the infrared burner head, and the ignition tube is placed on the gap opened by the infrared burner head protection net to ensure the success of the ignition. The change in the structure of the infrared burner caused by such an ignition method not only has a low ignition rate, but also forms a loophole in the protective net of the infrared burner, which affects the combustion effect and is unsightly.

This kind of portable oven usually uses a screw-in light steel cylinder to provide gas, and the steel cylinder can be screwed into the oven at any time according to the needs before use; , for the convenience of adjustment, it is usually necessary to turn the pressure reducing valve according to the direction of adjustment, so a set of screws is usually installed in front of the nozzle at the end of the gas outlet pipe, which is fixed in the screw hole corresponding to the end face of the air inlet hole of the furnace head, so that the pressure reducing The valve can rotate freely under the action of external force to facilitate the adjustment of firepower; when the oven is placed on the table for grilling, because the portable steel cylinders are often randomly configured, sometimes it is inevitable that the height from the bottom of the furnace body to the table is insufficient , then the steel cylinder needs to be placed obliquely.

At present, although some stove manufacturers hope to use the flame igniter on similar stoves; however, the flame igniter and the valve are integrated and cannot rotate freely; therefore, how to meet the needs Free-spinning pressure relief valve and cylinder connections? becomes a design problem.

Utility model content

The technical problem to be solved by the utility model is to provide a flame-spraying ignition oven device that does not need any modification to the burner head and can be plugged and connected with the burner head.

Another technical problem to be solved by the utility model is to provide an oven device that can quickly connect the pressure reducing valve and the gas bottle, and the pressure reducing valve can rotate freely, in view of the existing technical situation.

The technical scheme adopted by the utility model to solve the above-mentioned technical problems is: the oven device includes a burner head with an air intake pipe, an igniter and a pressure reducing valve, and the feature is that the igniter includes a gas channel inside. Gas valve and fire pipe, wherein the inlet end of the gas channel is connected to the pressure reducing valve, and the gas outlet end is the nozzle connected to the intake pipe of the burner head; one end of the fire pipe is connected to the gas channel, and the other end is the height of the fire port is equal to or slightly Height above the stove top. After the gas enters the gas channel of the gas valve from the pressure reducer, most of it enters the burner head through the nozzle, and a small part enters the flame nozzle. Light the gas going into the burner. Since the utility model is provided with a fire spray tube on the gas valve, the flame can be ignited directly to the infrared burner head, so there is no need to make any changes to the burner head, especially without setting a fire opening gap on the burner head. Easy to fire.

The flame spraying pipe can adopt a right angle and be arranged above the gas valve; the shape of the fire spraying pipe can also be arc or other shapes according to the needs of the actual structure or the preference of personal design.

In order to quickly connect the pressure reducing valve and the gas valve, and to achieve the purpose of freely rotating the pressure reducing valve, the inlet end of the gas channel can be connected to the pressure reducing valve through a quick connector. The use of the quick connector can make the gas valve and the pressure reducer quickly, safely and conveniently plugged in and separated, and the pressure reducing valve can be rotated at any angle.

Preferably, a connecting pipe can be provided between the inlet end of the gas valve gas channel and the quick connector, and the two are connected through the connecting pipe, which not only facilitates the assembly of the product, but also fully satisfies the freedom of rotation of the pressure reducing valve. At the same time, the gas bottle connected to the pressure reducing valve also needs to be separated from the gas valve by a certain distance to facilitate the placement of the gas bottle.

The connecting pipe can be connected with the male plug of the quick connector, and the female plug of the quick connector is fixed on the pressure reducing valve.

For the safety of use and the neat and beautiful appearance of the product, the air valve, connecting pipe and male plug can be arranged in the control box.

Compared with the prior art, since the utility model is equipped with a flame spray tube on the gas valve, the flame can be directly ignited to the infrared burner, so there is no need to make any changes to the burner, especially no need to install The ignition gap can be quickly and conveniently ignited; moreover, when the flame-throwing igniter is ignited, the flame range is large, and the ignition time can be controlled, so the one-time ignition rate is close to 100%; The use of joints can not only connect the corresponding pipelines quickly, safely and conveniently in an instant, but also solve the problem that the flame igniter cannot be rotated, and the pressure reducing valve can be rotated freely according to the needs of use.
