Description

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a burner of a gas device.

2. Description of the Related Art

A conventional burner generally includes a plurality of air inlet holes and a plurality of flame exit pores. Generally, each air inlet hole is of the same size with each flame exit pore.

Taiwan Pat. No. 1306498 discloses a burner for a gas device. The burner includes an inlet port, a passage, a plurality of air inlet holes, and a plurality of flame exit pores. Gas is to be directed into the burner through the inlet port and flows in the passage thereafter. Air is to be introduced into the burner through each air inlet hole for mixing with the gas in the passage. A flame, which is provided by combustion of a mixture of the gas and the air in the passage, can exit each flame exit pore. Each air inlet hole is designed to have a greater size than each flame exit pore. Therefore, air is introduced into the burner through each air inlet hole due to negative pressure effect. In contrast to the conventional burner that includes each air inlet hole having the same size with each flame exit pore, each air inlet hole and each flame exit hole of I306498 are different in size. Specifically, the air inlet hole is intended to be bigger for allowing a greater amount of air to be introduced into the burner, thereby alleviating a common incomplete combustion problem. However, the gas near the inlet port is still not mixed with the air thoroughly, thereby creating red flames in a region near the inlet port and resulting in an incomplete combustion in that region. Another problem is that the density of gas near a region far away from the inlet port is low as compared to that near the inlet port, thereby resulting in weak frames in that region.

The present invention is, therefore, intended to obviate or at least alleviate the problems encountered in the prior art.

SUMMARY OF THE INVENTION

According to the present invention, a burner of a gas device includes a first plate, a second plate engaged with and disposed opposite to the first plate, and a chamber formed by the first and second plates and partially delimited in the first plate and partially delimited in the second plate. The chamber includes first and second distal ends disposed at two opposite ends, and first and second lateral sides disposed at two opposite sides. The chamber further includes a gas inlet hole for allowing gas to enter into the chamber, which is disposed at the first distal end and includes an air inlet hole for allowing air to enter into the chamber, which is disposed at the first distal end. Furthermore, the chamber includes a first channel defined therein and connecting with the gas inlet hole and the air inlet hole, and a first compartment defined therein and connecting with the first channel. Moreover, the chamber includes a first plurality of flame exit pores and a second plurality of flame exit pores disposed at the first and second lateral sides respectively. The first and second plurality of flame exit pores connect with the first compartment.

It is an object of the present invention to provide a burner that avoids the problem of an incomplete combustion.

It is also an object of the present invention to provide a burner having a chamber that has a configuration that enables gas and air introduced therein to mix together thoroughly.
