Abstract
The utility model relates to a side-mounted structure of a fan of a domestic gas water heater, which comprises a gas collecting cover, a heat exchanger, a combustion chamber, and a fan. The fan is positioned at one side of the combustion chamber; an air outlet of the fan and an air inlet of the combustion chamber are in the same plane; an air flow reversing cover forming a cavity is arranged between the air outlet of the fan and the air inlet of the combustion chamber; the reversing cover is provided with an air inlet and an air outlet; the air inlet is communicated with the air outlet of the fan, and the air outlet is communicated with the air inlet of the combustion chamber. With the side arrangement and the additional arrangement of the air flow reversing cover not only enable the height of a water heater to be lowered but also enable the state of combustion to be better.
Description
The utility model relates to domestic gas-fired water heater, refers to forced burning formula domestic gas-fired water heater especially.
Present forced burning formula domestic gas-fired water heater, the blower fan of generally supplying with combustion air all is located at the below of burner.Because by the height sum decision of parts such as gas skirt, heat exchanger, combustion chamber, blower fan, because the height of blower fan is higher, so the total height of water heater is higher, therefore the occasion that water heater is installed is restricted the total height of water heater substantially.Many manufacturers once did effort for the height that reduces water heater, but produced little effect.
The purpose of this utility model is to propose a kind of blower fan side located structure of domestic gas-fired water heater, mat moves to its blower fan position one side of combustion chamber from the below of combustion chamber, the height of complete machine is greatly reduced, gas heater just can be in highly less space mounting like this, thereby makes the installation position of gas heater be equipped with the bigger free degree.
The blower fan side located structure of a kind of domestic gas-fired water heater of the present utility model, mainly comprise gas skirt, heat exchanger, the combustion chamber, blower fan, described blower fan places a side of combustion chamber, the air outlet of this blower fan and the air inlet of combustion chamber or be in same plane, or be higher than the combustion chamber air inlet, between the air inlet of the air outlet of described blower fan and combustion chamber, be provided with an airflow-reversing cover, described airflow-reversing cover is a cavity, which is provided with an air inlet and an air outlet, this air inlet is connected with the air outlet of described blower fan, and this air outlet is connected with the air inlet of described combustion chamber.
The utility model has the advantages that: (1) is because the side direction placement of blower fan, the position of former blower fan is replaced by the airflow-reversing cover, and the height of airflow-reversing cover will be much smaller than the height of blower fan, therefore greatly reduce the total height of water heater, water heater just can be installed in the smaller occasion in space like this, even can be installed in below the Kitchen stand in kitchen; (2) insert the airflow-reversing cover with a constant volume, be equivalent to insert an air-capacitor in gas circuit, air-flow is had integral action, can make the air-flow of output more stable, stable wind speed and blast can make the flame height in the combustion chamber better and more stable.
Now the utility model is described in further detail for an embodiment and in conjunction with its accompanying drawing.
Fig. 1 is the structural representation of an embodiment of the present utility model;
Fig. 2 is the schematic diagram of the airflow-reversing cover in the foregoing description.
An embodiment of the present utility model, as shown in Figure 1, mainly comprise gas skirt 1, heat exchanger 2, combustion chamber 3, blower fan 4, described blower fan 4 places a side of combustion chamber 3, the air outlet 41 of this blower fan 4 is in same plane with the air inlet 31 of combustion chamber 3, also can be higher than combustion chamber air inlet 31 in case of necessity, between the air inlet 31 of the air outlet 41 of described blower fan 4 and combustion chamber 3, be provided with an airflow-reversing cover 6, this airflow-reversing cover 6 is a cavity, an air inlet 61 and an air outlet 62 are arranged, this air inlet 61 is connected with the air outlet 41 of described blower fan 4, and this air outlet 62 is connected with the air inlet 31 of described combustion chamber 3.Air-flow by blower fan 4 is discharged behind this airflow-reversing cover 6, turns over 180 °, enters the air inlet 31 of combustion chamber 3.For reducing height, this airflow-reversing cover 6 is made into the cavity of flat, and described air inlet 61 is all established its upper side with air outlet 62, and as shown in Figure 2, the volume of its cavity needs to be complementary with the blast and the air quantity of blower fan 4 simultaneously.
The actual measurement proof, the wind speed and the blast of the each point of air-flow on air outlet 41 planes of directly being discharged by blower fan 4 were both inequality, also unstable, insert an airflow-reversing cover 6 with a constant volume, promptly be equivalent in gas circuit, insert an air-capacitor, integral action is arranged, can absorb the fluctuation of air-flow, make the air-flow of output more stable.Therefore air-flow is behind airflow-reversing cover 6, and the wind speed when being discharged by its air outlet 62 is all more stable and consistent with blast.When the blast of the volume of airflow-reversing cover 6 and blower fan 4 and air quantity were complementary, the height of the flame in the combustion chamber 3 and stability were all very good.The blast that example is worked as blower fan is 20mmH
2O, nominal air delivery are 0.75m
3During/min, the volume of described airflow-reversing cover 6 can be chosen and be not less than 3.0 * 10
-4m
3In order to reduce the total height of water heater, the height of airflow-reversing cover 6 should be got smaller value, but is advisable to be not less than 15mm.Because the height of blower fan 4 generally reaches 160mm, and the height of airflow-reversing cover 6 only is 15-30mm, so the height of water heater reduces fairly obvious.
In sum, the utility model has not only reduced the height of water heater, and has improved the combustion position of water heater.
