Referring to fig. 1 to 5, an outdoor gas water heater according to an embodiment of the present invention includes a housing 10, a combustion heat exchange device 20, a smoke collecting chamber 31, and a diffusion chamber 41.
A mounting chamber 11 is provided in the housing 10, and a first exhaust port 12 communicating with the top of the mounting chamber 11 is provided in the housing 10. Further, first air inlets 13 are provided at opposite sides of the cabinet 10, respectively. The combustion heat exchange device 20, the smoke collecting cavity 31 and the diffusion chamber 41 are all arranged in the installation cavity 11, the combustion heat exchange device 20 comprises a fire row 21 and a heat exchanger 22, and the fire row 21, the heat exchanger 22 and the smoke collecting cavity 31 are sequentially arranged from bottom to top. The diffusion chamber 41 communicates with the side of the smoke collecting chamber 31, and a second exhaust port 42 communicating with the diffusion chamber 41 is provided in the installation chamber 11, and the second exhaust port 42 communicates with the bottom of the diffusion chamber 41.
In normal operation, the flue gas flows upwardly through the heat exchanger 22 and the plenum 31 and then out through the first exhaust port 12, and since the flue gas is normally rising, little or no flue gas flows into the diffusion chamber 41. At the same time, the rising smoke can reduce the air pressure in the smoke collecting cavity 31 to suck the outside air into the mounting cavity 11. When the first exhaust port 12 is blocked, the smoke cannot flow out through the first exhaust port 12, and at this time, the smoke can flow into the diffusion chamber 41, and when the smoke in the diffusion chamber 41 is more, the smoke can flow out through the second exhaust port 42. Therefore, the flow of the smoke can be ensured, the accumulation of the smoke is avoided, and the exceeding of the smoke concentration in the water heater is avoided, so that the requirements of relevant authentication tests can be met when the smoke concentration test is carried out.
The flow of the flue gas enables the external fresh air to flow into the installation cavity 11 so that the fuel can be fully combusted, and the generation of harmful substances is reduced, so that the content of the harmful substances in the flue gas is ensured to be lower than the relevant standard.
When the water heater is just ignited and the flame is just extinguished, the fuel is not fully combusted, more harmful substances can be generated, the harmful substances in the smoke exceed the standard, the temperature of the smoke is low at the moment, the rising trend of the smoke is not obvious, the exceeding smoke can transversely escape into the diffusion chamber 41, part of exceeding smoke temporarily stays in the diffusion chamber 41, and a large amount of exceeding smoke is prevented from rapidly escaping to the outside.
In addition, an air flow sensor may be disposed at the top of the smoke collecting chamber 31, and a control system may be disposed on the casing 10, and the air flow sensor may be electrically connected to the control system. The shell 10 is also provided with an air inlet nozzle 15 for installing a fuel bottle, the air inlet nozzle 15 is communicated with a fire row 21 through an air inlet pipeline 16, the air inlet pipeline 16 is provided with an electromagnetic valve 17, and the electromagnetic valve 17 is also electrically connected with a control system. The electromagnetic valve 17 can control the on-off of the air inlet pipeline 16. When the first exhaust port 12 is clogged, the airflow speed detected by the airflow sensor becomes small, even zero. When the air flow rate is lower than a certain set value, the control system controls the electromagnetic valve 17 to operate, and cuts off the fuel supply to the fire grate 21 to stop combustion. Before stopping combustion, the flue gas generated by combustion may flow into the diffusion chamber 41.
Since the second exhaust port 42 is located in the installation cavity 11, external wind can be prevented from directly blowing to the second exhaust port 42 to inhibit the outflow of smoke during the wind-up.
Referring to fig. 3, a fume collecting hood 30 is provided in the installation chamber 11, and a fume collecting chamber 31 is provided in the fume collecting hood 30. A diffusion hood 40 is provided laterally of the fume collecting hood 30, and a diffusion chamber 41 is located in the diffusion hood 40. The second exhaust port 42 is provided on the diffusion cover 40.
In some embodiments, the diffusion hood 40 may be connected to the fume collection hood 30, i.e., the diffusion hood 40 and fume collection hood 30 together enclose a diffusion chamber 41.
Referring to fig. 3 and 4, first exhaust ports 12 are provided at opposite sides of the cabinet 10, a wind shielding structure 50 is provided at the top of the installation cavity 11, the wind shielding structure 50 includes a mounting plate 51 and a baffle plate 52, the mounting plate 51 is rotatably disposed in the installation cavity 11, the baffle plate 52 is provided at both sides of the mounting plate 51, and the baffle plate 52 is inclined downward.
When blowing wind, wind can be blown in from the first air outlet 12 on one side of the casing 10, the blown-in air flow drives the wind shielding structure 50 to rotate, the wind shielding structure 50 can shield the first air outlet 12 on the side, the condition that the outside air is filled into the smoke collecting cavity 31 to block the outflow of smoke is avoided, and meanwhile, the smoke in the smoke collecting cavity 31 can flow out through the first air outlet 12 on the other side of the casing 10. Therefore, by arranging the wind shielding structure 50, even when the wind blows, the smoke can be ensured to flow out, the accumulation of the smoke is avoided, and meanwhile, the outside fresh air can flow into the mounting cavity 11, so that the fuel can be fully combusted, and the generation of harmful substances is reduced.
The mounting plate 51 and the baffle plate 52 can be in an integrated structure, and during production, a sheet can be bent to form the mounting plate 51 and the baffle plate 52, so that the number of parts is reduced, and the production cost is reduced.
The combustion heat exchange device 20 is located between the first air inlets 13 on both sides of the casing 10. When the wind blows to one side of the casing 10, the air is shielded by the combustion heat exchange device 20, so that the air flow can be prevented from directly penetrating through the casing 10, and a part of air can be blown into the installation cavity 11 to assist combustion, and the condition of insufficient fuel combustion is avoided.
Referring to fig. 1 and 2, a second air inlet 14 and a first baffle 61 extending downward are provided at the bottom surface of the cabinet 10, and the first baffle 61 has a cross-shaped cross section. During windy, the air flow passes through the lower part of the casing 10, and the first baffle 61 can prevent the air flow from directly flowing through the lower part of the casing 10, so that part of the air can enter the mounting cavity 11 through the second air inlet 14 to assist combustion, and insufficient fuel combustion is avoided.
Further, a guide plate 62 is disposed at the bottom of the first baffle plate 61, two sides of the guide plate 62 are respectively provided with a second baffle plate 63 extending downward, and the second baffle plates 63 at two sides of the guide plate 62 are staggered back and forth. When the wind blows to one side of the casing 10, the second deflector 63 can block the air flow, and prevent the air from directly flowing under the casing 10, so that part of the air can enter the installation cavity 11 through the second air inlet 14 to assist combustion. In addition, the second baffle plates 63 on two sides of the guide plate 62 are staggered back and forth, so that part of air bypasses the second baffle plates 63 to reach the other side of the casing 10, the flow rate of the air reaching the other side of the casing 10 is low, and the air at the other side of the casing 10 is not completely blown away, so that enough air is ensured to enter the installation cavity 11 from the other side of the casing 10 to assist combustion, and the condition of insufficient fuel combustion is avoided.
In some embodiments, the first baffle 61 may also be in-line or wavy in cross-section.
In some embodiments, the second exhaust port 42 may be provided on an outer sidewall of the cabinet 10. Accordingly, a downwardly extending windshield may be provided on the cabinet 10 such that the second exhaust port 42 faces downward, preventing the air flow direction from facing the second exhaust port 42 during a wind-up.
An anti-toppling switch (not shown in the drawings) is also provided in the housing 10, and is electrically connected to the control system, and detects the inclination of the housing 10, and cuts off the fuel supply by the solenoid valve 17 when the housing 10 topples, so as to stop combustion.
