The first embodiment:

referring to fig. 1, the utility model discloses a gas heater falls shell of making an uproar includes in the first embodiment: a housing 1 and an inner partition 2. The housing 1 is provided with a first air inlet 11. The inner partition 2 is disposed in the housing 1, a first cavity 13 (see fig. 5) is formed between the inner partition 2 and the housing main body 12 of the housing 1, and a second cavity 15 (see fig. 5) is formed between the inner partition 2 and the side plate 14 of the housing 1. Importantly, referring to fig. 2 and 5 (see fig. 5 and fig. 4), the inner partition 2 is provided with a louver 21 having a second air inlet 211; the first air inlet 11, the second cavity 15, the second air inlet 211 and the first cavity 13 are sequentially communicated. With the arrangement, when the outside air enters the first cavity 13, the air flows in the sequence of the first air inlet 11 → the second cavity 15 → the second air inlet 211 → the first cavity 13; similarly, the noise reduction housing for the gas water heater is disposed in the first cavity 13, so that when noise is transmitted from the first cavity 13 to the outside, the noise transmission route is sequentially the first cavity 13 → the second air inlet 211 → the second cavity 15 → the first air inlet 11. The second air inlets 211 based on the louver 21 are distributed at intervals and have small sizes, thereby having an obvious noise blocking effect. Moreover, the second air inlet 211 is covered by the blades 212 of the louver 21, so that part of the noise can be directly intercepted to prevent the noise from entering the second air inlet 211, thereby further reducing the noise. In particular, the flow cross-section of the flow tube is larger based on both the first cavity 13 and the second cavity 15 according to the flow continuity equation. When noise passes through the second air inlet 211 from the first cavity 13, the flow cross section of the flow pipe becomes smaller; when the air continues to enter the second cavity 15 from the second air inlet 211, the flow cross section of the flow pipe is increased; when the air enters the first air inlet 11 from the second cavity 15, the through-flow section of the flow pipe is reduced; finally, when the air enters the external environment from the first air inlet 11, the through-flow section of the flow pipe is enlarged; therefore, the noise is greatly attenuated when being transmitted to the external environment through blocking and attenuation for many times, so that the effect of reducing the noise is effectively realized. Therefore, in the optimal product, the ratio of the effective sectional area of the first air inlet 11 to the effective sectional area of the second cavity 15 is between 0.6 and 0.9; the ratio of the total effective sectional area of the second inlet 211 to the effective sectional area of the second chamber 15 is between 0.7 and 0.95.

Preferably, referring to fig. 1 and 5, the inner partition 2 is disposed at the top of the housing 1, the bottom of the vane 212 of the louver 21 is connected with the bottom of the second air inlet 211, and the top of the louver 21 extends obliquely in the height direction and in the direction away from the second chamber 15. With such an arrangement, when the noise is transmitted from bottom to top, the noise is blocked by the blades 212 of the louver 21 and cannot enter the second air inlet 211, and only after the noise bounces back from the top of the housing 1, a part of the noise may enter the second air inlet 211, thereby greatly reducing the noise pollution of the gas water heater. More preferably, referring to fig. 5, the first intake vent 11 is located below the second intake vent 211. So set up, when the noise got into second cavity 15 from first cavity 13 through second air intake 211, based on first air intake 11 was located the below of second air intake 211, still need be propagated to the direction of height based on the noise, just can downwards directive first air intake 11 after the bounce, even make the noise can't directly be from second air intake 211 directive first air intake 11 to further reduce gas heater's noise pollution.

Preferably, referring to fig. 1 and 5, the connection between the inner partition 2 and the side plate 14 of the housing 1 is hermetically connected by a sealing ring 3. By the arrangement, the inner partition plate 2 can not only play a role in sealing to further reduce noise, but also buffer the mutual collision between the inner partition plate 2 and the shell 1, thereby avoiding the generation of resonance noise. Further, the vibration energy can be effectively consumed by the cushioning of the seal ring 3, thereby further reducing noise pollution.

Referring to fig. 1 and 3, the gas water heater of the present invention comprises: a burner device 4, a heat exchanger device 5 and a fan device 6 and the noise reduction shell of the gas water heater. The burner device 4, the heat exchanger device 5 and the fan device 6 are all positioned in the first cavity 13 and are communicated in sequence according to the gas flow direction; the burner device 4 is provided with an air inlet 41 communicated with the first cavity 13, the shell 1 is provided with a through hole 16 communicated with the outside, and a smoke outlet 65 of the fan device 6 is connected with the through hole 16. So, the inside gas flow direction of gas heater does: first cavity 13 → air intake hole 41 → burner means 4 → heat exchanger means 5 → fan means 6 → liquid outlet → external noise-proof duct. The connection position of the fan device 6 and the heat exchanger device 5 is positioned below the shutter 21; the connection of the heat exchanger device 5 to the burner device 4 is located below the louvers 21. With this arrangement, when noise generated by collision between elements is transmitted from bottom to top, the bottom of the louver 21 is connected to the bottom of the second air inlet 211 based on the inner partition 2 being provided at the top of the housing 1, and the top of the louver 21 extends obliquely in the height direction and in the direction away from the second chamber 15; so that the noise is not easily passed from the first chamber 13 to the second air inlet 211 to enter the second chamber 15, thereby facilitating the noise to be consumed in the first chamber 13. More preferably, referring to fig. 1 and 3, the burner apparatus 4, the heat exchanger apparatus 5 and the blower apparatus 6 are connected in order in the height direction, and the air intake holes 41 of the burner apparatus 4 are provided at the bottom of the burner apparatus 4. So arranged, the junction of the heat exchanger device 5 and the burner device 4 is located at the bottom of the housing 1, i.e. farther away from the louver 21, and thus less likely to pass through the louver 21, thereby further reducing the noise pollution of the gas water heater.

Preferably, referring to fig. 1 and 3, the fan device 6 includes a hood assembly 61 connected to the heat exchanger device 5, a scroll 62 connected to the hood assembly 61, a motor assembly 63 connected to a turbine within the scroll 62, and a chill wheel 64 for cooling the motor assembly 63. The motor assembly 63 and the cool wind wheel 64 are disposed at a side of the first cavity 13 away from the louver 21, and the motor assembly 63 and the cool wind wheel 64 are disposed in a staggered manner with respect to the louver 21 in a horizontal plane. In this way, part of the noise generated by the motor assembly 63 and the cooling wind wheel 64 can be reduced to pass through the shutter 21, thereby reducing the noise pollution of the gas water heater as much as possible. More preferably, the inner partition 2 is provided with a noise grill 22 extending in the gravity direction, the motor assembly 63 and the cool air wheel 64 are located on a horizontal first side 221 of the noise grill 22, and the louver 21 is located on a horizontal second side 222 of the noise grill 22 disposed opposite to the horizontal first side 221. This is arranged so that the louver 21 is directly shielded by the noise grill 22, thereby preventing more noise from passing through the louver 21.

The second is the embodiment:

the second embodiment includes the first embodiment, which is different from the first embodiment in that: as an alternative arrangement of the louver 21, the inner partition 2 is disposed at the bottom of the housing 1, the top of the vane 212 of the louver 21 is connected with the top of the second air inlet 211, and the bottom of the louver 21 extends obliquely in the direction of gravity and in the direction away from the second cavity 15. Similarly, the arrangement is similar to the principle, only the position of the louver 21 is changed, and the noise reduction effect of the louver is not greatly different from that of the louver when the inner partition 2 is arranged at the top of the shell 1, namely the arrangement mode is the same optimized arrangement mode. However, the component layout of the first embodiment is relatively suitable for the installation and use requirements of the product.

In the detailed description of the embodiments, various technical features may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.

The detailed description of the above embodiments only expresses several embodiments of the present invention, and the description thereof is more specific and detailed, but should not be construed as limiting the scope of the present invention. It should be noted that, for those skilled in the art, without departing from the concept of the present invention, several variations and modifications can be made, which all fall within the scope of the present invention.
