Detailed Description

The present invention will be further described by way of examples with reference to the accompanying drawings, but the present invention is not limited thereto.

As shown in fig. 1-2, the gas distributor 100 includes: a shell 110, a first-stage nozzle 111, a second-stage nozzle 112 and a partition plate 120.

The partition plate 120 divides the inner cavity of the housing 110 into a first-stage chamber 151 and a second-stage chamber 152, the first-stage nozzle 111 is disposed in the first-stage chamber 151, and the second-stage nozzle 112 is disposed in the second-stage chamber 152.

The gas distributor 100 further includes a baffle 130, the baffle 130 is disposed in the two-stage chamber 152 and extends from the partition plate 120, and the extension direction of the baffle 130 is the same as the arrangement direction of the two-stage nozzles 112.

The two-stage chamber 152 of the gas distributor 100 is provided with a baffle 130, and the baffle 130 can guide the gas in the two-stage chamber 152 to the two-stage nozzle 112 in the two-stage chamber 152, which is far from the gas inlet, so as to avoid unsmooth fire transmission in the two-stage nozzle 112.

As shown in fig. 2, the baffle 130 and the partition plate 120 are formed together in a substantially Y-shaped structure.

The two-stage nozzle 112 is arranged such that the ratio of the length of the line segment to the extended length of the baffle 130 is 5: 1.

If the extended length of the baffle 130 is too long, the two-stage nozzle 112 near the splitter plate 120 may not easily contact the gas, and the fire may be more smoothly transferred, so that the ratio of the length of the line segment formed by the two-stage nozzle 112 to the extended length of the baffle 130 is limited to 5:1, which may guide the gas entering from the two-stage gas inlet 142 to the two-stage nozzle 112 further away (left side in the drawing), and may not greatly reduce the gas receiving capacity of the two-stage nozzle 112 near the splitter plate 120.

The casing 110 is provided with a first section of the air inlet 141 and a second section of the air inlet 142, the first section of the nozzle 111 and the second section of the nozzle 112 are arranged on a first surface 161 of the casing 110, the first section of the air inlet 141 and the second section of the air inlet 142 are arranged on a second surface 162 of the casing 110, and the second surface 162 is perpendicular to the first surface 161.

The arrangement surfaces of the first-stage nozzle 111 and the second-stage nozzle 112 are perpendicular to the arrangement surfaces of the first-stage air inlet 141 and the second-stage air inlet 142.

The first-stage intake port 141 and the second-stage intake port 142 are disposed near the partition plate 120.

The number of two-stage nozzles 112 is larger than the number of one-stage nozzles 111. The two-stage nozzle 112 is a nozzle that is activated when the temperature demand of the gas water heater 200 is high, the one-stage nozzle 111 is a nozzle that is activated when the temperature demand of the gas water heater 200 is low, and the one-stage nozzle 111 is activated before the two-stage nozzle 112, so that the number of nozzles of the two-stage nozzle 112 is large, so as to meet the requirement of the gas water heater 200 for rapid temperature rise.

In the present embodiment, the number of the two-stage nozzles 112 is twice the number of the one-stage nozzles 111. However, the present invention is not limited to this, and the ratio of the number of the two-stage nozzles 112 to the number of the one-stage nozzles 111 may be set as needed.

The partition plate 120 includes a first portion 121, a second portion 122, and a third portion 123 connected in sequence, the first portion 121 extending perpendicular to the second surface 162, the third portion 123 extending perpendicular to a third surface 163, the third surface 163 being opposite to the second surface 162, and the baffle 130 being connected to the junction of the third portion 123 and the second portion 122.

The first portion 121 of the partition plate 120 is disposed perpendicular to the second surface 162 so that the partition plate 120 does not obstruct the gas from entering from the one-stage gas inlet port 141. The third portion 123 of the partition plate 120 extends perpendicular to the third surface 163 so that the partition plate 120 does not prevent the combustion gas from contacting the first-stage nozzle 111 and the second-stage nozzle 112.

The distance between the baffle 130 and the two-stage nozzle 112 is half the distance between the baffle 130 and the second surface 162.

The distance between the baffle 130 and the secondary nozzle 112 being half the distance between the baffle 130 and the second surface 162 may facilitate the baffle 130 to better direct the fuel gas entering from the secondary inlet 142.

The opening areas of the first-stage air inlet 141 and the second-stage air inlet 142 are generally set according to the power of the gas water heater 200 when the gas water heater 200 is shipped and are also fixed. However, the present invention is not limited thereto, the opening area of the first air inlet 141 and/or the second air inlet 142 is adjustable, for example, a rotatable baffle may be disposed on the first air inlet 141 and/or the second air inlet 142 to adjust the opening area of the first air inlet 141 and/or the second air inlet 142, and the rotation of the rotatable baffle may be controlled manually or automatically.

The present embodiment also provides a gas water heater 200, and the gas water heater 200 includes the gas distributor 100 as above.

Cold water enters from the water inlet connection 202 and flows through the heat exchanger assembly 210 and exits from the water outlet connection 203. The gas enters from the gas inlet connector 201, passes through the proportional valve assembly 204, enters the gas distribution chamber, is sprayed into the combustion chamber box 208 through the nozzle of the gas distribution chamber, meanwhile, the fan component 206 conveys air to the interior of the combustion chamber box 208, the gas and the air are mixed and combusted in the interior of the combustion chamber box 208, the generated flue gas flows upwards and flows through the heat exchanger component 210, and finally the flue gas flows out from the gas collecting hood component 211.
