The motor 500, the partition box 400, the smoke exhaust impeller 640, the volute 620, the smoke cage 630, the cooling impeller 910, the fixing frame 920, the heat exchanger 700, and the burner 800 are installed inside the casing 100. The specific structure of the partition box 400 includes: a first sidewall, a partition cover 420, and a partition plate 430, wherein the first sidewall is a part of the case 100. The partition plate 430 is provided with a through-shaft hole 432, the partition cover 420 is provided with a first flanging group 421 and a second flanging group 422, the first flanging group 421 is fixedly connected with the partition plate 430, the second flanging group 422 is fixedly connected with the first side wall, and the third flanging group 431 is fixedly connected with the first side wall. The first side wall, the partition cover 420 and the partition plate 430 enclose an installation space, and the motor 500 is installed in the installation space, wherein the power shaft 510 of the motor 500 penetrates through the through shaft hole 432. The volute 620 is provided with a smoke exhaust 610 and a smoke exhaust impeller 640 is disposed inside the volute 620. The fixing frame 920 is installed on the partition plate 430, a movable space is formed between the fixing frame 920 and the partition plate 430, the cooling impeller 910 is located in the movable space, and the power shaft 510 of the motor 500 sequentially passes through the through-shaft hole 432, the cooling impeller 910 and the fixing frame 920 and is connected with the smoke exhaust impeller 640. The smoke exhaust pipe 300 and the air inlet pipe 200 are coaxially arranged, the smoke exhaust port 610 is in butt joint with the smoke exhaust pipe 300, and the air inlet pipe 200 is in butt joint with the air inlet 110. The lower part of the burner 800 is provided with an air inlet for receiving combustion air, the position of the air inlet is taken as the lower part, the heat exchanger 700 is positioned above the burner 800, the heat exchanger 700 is provided with a flue gas outlet, and the flue gas outlet is covered by the smoke hood 630.

When the gas water heater is operated, combustion air is introduced from the air inlet pipe 200 and introduced into the interior of the outer case 100 through the air inlet 110, and then flows down to the lower portion of the burner 800, and is introduced into the burner 800 through the air inlet. The burner 800 burns combustion air and generates flue gas, which is discharged through the flue gas outlet of the heat exchanger 700 and collected by the hood 630, discharged from the smoke discharge port 610 by the smoke discharge impeller 640, and discharged to the outside of the gas water heater through the smoke discharge pipe 300. This is substantially the case throughout the work flow of a gas water heater, in fig. 1, the solid arrows substantially indicate the movement trajectory of the combustion air, and the dashed arrows substantially indicate the movement trajectory of the flue gas.

Since the motor 500 is not heat-resistant and the combustion air has a certain high temperature, in the present embodiment, the combustion air passes through the air inlet pipe 200 and is heated by the flue gas in the smoke exhaust pipe 300 in the process of passing through the air inlet pipe 200, so that the combustion air has a high temperature. The temperature of the flue gas discharged from the smoke discharge pipe 300 can reach 140 ℃ generally, and the temperature of the combustion air at the moment can reach 70 ℃. Of course, the high temperature source of combustion air may also be derived from other means. The combustion air of high temperature flows in the inner space of the housing 100, thereby heating the motor 500. The utility model discloses the creative inner space through separating box 400 with motor 500 and shell 100 parts, blocks the combustion air of high temperature to motor 500's influence for motor 500 works in a temperature relatively lower environment, improves motor 500's life, improves gas heater's life then.

In some embodiments, the partition box 400 may be constructed in various ways, and the specific partition box 400 may be constructed in different ways according to actual needs. Specifically, the sheet-like member may be enclosed into a box shape by a plurality of sheet-like members. And a mounting lug is provided at a certain sidewall of the partition box 400. When the partition box 400 is installed, the motor 500 may be installed inside the partition box 400 in advance, and then fixedly connected to the housing 100 through the installation lugs. Of course, it is preferable to use a portion of the casing 100 as a sidewall of the partition box 400, which not only saves materials, but also facilitates the contact with the outside air, and plays a certain role in dissipating heat of the partition box 400.
