Further, the air inlet set up in the rear side cambered surface of dustcoat, the gas outlet set up in the front side cambered surface of bellying, the air inlet with the gas outlet is 180.
Further, the air inlet and the air outlet are a plurality of strip-shaped holes.
Furthermore, the motor, the fan assembly, the heat exchanger assembly, the combustion chamber assembly and the burner assembly of the gas water heater are sequentially arranged from top to bottom.
Further, the air outlet faces the motor.
Furthermore, the area of the air inlet is more than or equal to 500mm2The outer circumference of the convex part is more than or equal to 300 mm.
The utility model has the beneficial effects that:
the sound propagation channel and the air flow channel are formed in the shell of the gas water heater, on one hand, the noise generated by the water heater is attenuated in the shell propagation process, so that the diffusion propagation of system noise is effectively reduced, the product noise is reduced, and meanwhile, the air outside the shell enters the water heater through the channel, so that the heat dissipation of key components inside the water heater is realized.
Additional aspects and advantages of the utility model will be set forth in part in the description which follows and, in part, will be obvious from the description, or may be learned by practice of the utility model.

the air conditioner comprises an upper shell 10, a convex part 20, an outer cover 30, an air outlet 21, an air inlet 31, a hollow chamber 40, a motor 50, a fan assembly 60, a heat exchanger assembly 70, a combustion chamber assembly 80 and a burner assembly 90.
Detailed Description
The present invention will now be described in detail with reference to the accompanying drawings. This figure is a simplified schematic diagram, and merely illustrates the basic structure of the present invention in a schematic manner, and therefore it shows only the constitution related to the present invention.
In the description of the present invention, it is to be understood that the terms "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "top," "bottom," "inner," "outer," and the like are used in the orientations and positional relationships indicated in the drawings for convenience in describing the present invention and for simplicity in description, and are not intended to indicate or imply that the referenced devices or elements must have a particular orientation, be constructed in a particular orientation, and be operated in a particular manner and are not to be construed as limiting the present invention.
Referring to fig. 1-4, the gas water heater of the present invention comprises an upper housing 10, a motor 50, a fan assembly 60, a heat exchanger assembly 70, a combustion chamber assembly 80, and a burner assembly 90 are arranged in the water heater from top to bottom, the upper housing 10 is provided with a cylindrical protruding portion 20 for conveniently mounting the motor 50, an outer cover 30 is fixedly mounted outside the protruding portion 20, the protruding portion 20 is provided with an air outlet 21, the outer cover 30 is provided with an air inlet 31, and the protruding portion 20 and the outer cover 30 enclose to form a hollow chamber 40.
The hollow chamber 40 is a passage for outside air to enter the water heater, the outside air can enter the machine to reduce the temperature rise of the surfaces of all elements, the hollow chamber 40 is also a passage for the noise of the water heater to spread outwards, and the noise is effectively attenuated in the hollow chamber 40 in the spreading process, so that the noise of the product is effectively reduced.
As shown in fig. 4, after entering the hollow chamber 40 through the air inlet 31, the outside air flows out from the air outlet 21 into the water heater, so as to cool the internal components of the water heater. The propagation direction of the water heater noise is opposite, the noise is propagated from the air inlet 31 to the outside of the machine after entering the hollow chamber 40 from the air outlet 21, and the noise is effectively attenuated in the propagation process, particularly in the propagation process of the hollow chamber 40.
Further specifically, air inlet 31 sets up in the rear side cambered surface of dustcoat 30, and gas outlet 21 sets up in the preceding cambered surface of bellying 20, and air inlet 31 and gas outlet 21 are 180, can prolong the propagation path of noise in order to promote the noise reduction effect from this, and the preceding cambered surface that the gas outlet 21 selection set up in bellying 21 faces motor 50 simultaneously, and outside air can carry out the heat transfer cooling that lasts to motor 50 after entering into the water heater inside from gas outlet 21 to extension motor 50's life. In addition, the area of the second air inlet is designed to be more than or equal to 500mm2The outer circumference of the bulge is more than or equal to 300mm, the requirement on installation size is guaranteed, meanwhile, the contact area of the inner wall of the hollow cavity 40 and the air inlet flow can be guaranteed, and the noise reduction and heat dissipation effects are improved.
