The utility model provides a shell subassembly 100 is applicable to gas heater, gas heater includes water heater body 70.

In the embodiment of the present invention, as shown in fig. 1, 6 and 7, the housing assembly 100 includes a face shell 20 and a reinforcing plate 30, and a display control assembly 60 is disposed on one side of the face shell 20; the reinforcing plate 30 is coupled to the face housing 20 and forms a cavity 40 between the reinforcing plate 30 and the face housing 20.

It can be understood that the display control component 60 is used for displaying parameters such as water temperature of the gas water heater and controlling the gas water heater by a user, so when the gas water heater is installed, the side of the water heater having the display control component 60 is usually set towards the user, so that the user can conveniently view and control the water heater.

It should be noted that when the combustion in the gas water heater is unstable, the pressure inside the gas water heater changes due to the pressure change of the inlet and outlet gases, and a fluctuating pressure difference is formed between the inside and the outside of the gas water heater, so that the gas flow generated in the gas water heater is agitated, and the resonance or shake of the face shell 20 is caused, thereby generating noise. Also, the gas water heater body 70 generates noise during operation, and the noise is transmitted to the outside of the gas water heater through the panel case 20. It can be known that, on display control assembly 60 located face-piece 20, face-piece 20 was the water heater towards the one side that the user set up, if face-piece 20 produced the noise, can cause great influence to user experience, was equipped with mounting hole 22 because of the panel, led to the sound insulation performance of panel also to descend to some extent.

According to the technical scheme of the utility model, the rigidity of the face shell 20 is improved by arranging the reinforcing plate 30, so that the natural vibration frequency of the face shell 20 is improved, when the pressure in the cavity of the gas water heater is changed due to unstable combustion inside the gas water heater, the face shell 20 is not easy to generate bending vibration, namely bending waves are not easy to generate, the resonance amplitude and the generated vibration noise of the face shell 20 are weakened, and the noise generated by the gas water heater is further reduced; and, a cavity 40 is formed between the reinforcing plate 30 and the face shell 20, so that the noise is transmitted from the inside of the gas water heater to the outside of the propagation path, the level of the propagation medium of the noise becomes more complicated, the noise needs to be propagated to the outside of the gas water heater through the reinforcing plate 30, the cavity 40 and the face shell 20, and the noise is weakened in the propagation process due to the change of the propagation medium, so that the noise emitted by the gas water heater is weakened, and the noise emitted by the gas water heater is further reduced.

In the present embodiment, the cavity 40 is a sealed cavity 40. When noise passes through the cavity 40, sound waves collide back and forth inside the cavity 40, and the sound wave energy is converted into mechanical energy, so that the noise is attenuated during the collision. In this embodiment, the cavity 40 is sealed, that is, the cavity 40 is not communicated with the inside or the outside of the gas water heater, so as to ensure that the sound waves repeatedly collide in the cavity 40 and are not transmitted from the gap at the joint of the face shell 20 and the reinforcing plate 30, thereby increasing the reflection times of the sound waves in the cavity 40 and further ensuring the noise reduction effect.

In other embodiments, the cavity 40 may be a non-sealed cavity 40, and the cavity 40 is communicated with the inside of the gas water heater. In the process of producing the gas water heater, the sealing requirement for the connection between the face shell 20 and the reinforcing plate 30 is relatively lower, so that the production process is simpler, thereby improving the production efficiency.

In the embodiment, the cavity 40 is filled with air, and the space for producing the gas water heater is filled with air, so that when the cavity 40 is formed, the reinforcing plate 30 is adhered to the face shell 20 to directly form the cavity 40 with air, and the production process is simple.

In other embodiments, it is also possible that the cavity 40 is vacuum-set, and the sound attenuation effect of the vacuum-set cavity 40 is relatively better.

In this embodiment, the outer edge of the reinforcing plate 30 at least partially has a folded edge toward the inner side of the panel case 20, and the height of the folded edge is smaller than the thickness of the air cavity, so as to improve the strength of the edge of the reinforcing plate 30.

In one embodiment, as shown in fig. 1 and 5, the reinforcing plate 30 is connected to the inner side of the front cover 20, and the reinforcing plate 30 is provided with an escape portion at a position opposite to the display control unit 60.

It will be appreciated that the display control assembly 60 is connected to the burner 71 in the housing assembly 100 to control the operation of the burner 71, and therefore the stiffener plate 30 needs to be provided with an escape portion to avoid the display control assembly 60. Alternatively, the avoiding portion may be a notch provided at the edge of the reinforcing plate 30, or may be a through hole 35.

In one embodiment, as shown in fig. 1 and 4, a mounting hole 22 is formed on the front cover 20, the display control assembly 60 is disposed on the mounting hole 22, the avoiding portion is a through hole 35, and the through hole 35 is used for mounting the display control assembly 60.

In the present embodiment, the display control assembly 60 is positioned and mounted by providing mounting holes 22 on the front cover 20. The size of reinforcing plate 30 is similar with face-piece 20 size, and reinforcing plate 30 keeps away the position with display control subassembly 60 through setting up through-hole 35, and through-hole 35 is used for supplying display control subassembly 60 to pass.

In the present embodiment, the periphery of the mounting hole 22 is bent toward the direction of the reinforcing plate 30 to form a detent 221, and the display control assembly 60 is embedded in the detent 221, so that the outward surface of the display control assembly 60 does not protrude out of the outward surface of the panel 20, thereby preventing the display control assembly 60 from being knocked, and being more beautiful. The reinforcing plate 30 is connected to the locking portion 221 through the through hole 35, so that the reinforcing plate 30 can be conveniently positioned and mounted on the face shell 20.

In an embodiment, as shown in fig. 1, the reinforcing plate 30 is a metal plate, the reinforcing plate 30 protrudes away from the face shell 20 to form a protrusion 31, the cavity 40 is formed between the protrusion 31 and the face shell 20, and a thickness of the cavity 40 is not less than 0.2 cm and not more than 1.8 cm.

In the embodiment, the face shell 20 and the reinforcing plate 30 are made of metal, and the reinforcing plate 30 is fixed to the face shell 20 by bonding, welding, or bolting, so as to enhance the connection strength between the face shell 20 and the reinforcing plate 30, thereby improving the rigidity of the face shell 20.

In the present embodiment, a part of the side wall of the reinforcing plate 30 facing the face shell 20 protrudes in a direction away from the face shell 20 to form the protrusion 31, that is, a distance is provided between the protrusion 31 and the face shell 20, and the distance between the protrusion 31 and the face shell 20 is the thickness of the cavity 40.

In the present embodiment, the side wall of the protrusion 31 facing away from the face shell 20 protrudes toward the direction away from the face shell 20, and is matched with the side wall of the protrusion 31 facing toward the face shell 20, so that the thickness of the whole reinforcing plate 30 is uniform, and the production is easy, for example, the reinforcing plate 30 can be directly manufactured by stamping; moreover, the reinforcing plate 30 has better stress resistance, is not easy to deform and has longer service life.

In other embodiments, the face shell 20 may be arched outward to form an arch, and the arch and the stiffener plate 30 may form a cavity 40 therebetween. Alternatively, the face shell 20 may be arched outward to form an arched portion, the reinforcing plate 30 may be protruded away from the face shell 20 to form a protrusion 31, and a cavity 40 may be formed between the protrusion 31 and the arched portion.

It is understood that if the thickness of the cavity 40 is less than 0.2 cm, a good noise reduction effect cannot be achieved, and if the thickness of the cavity 40 is greater than 1.8 cm, air vibration inside the cavity 40 may be caused, increasing noise. Therefore, the thickness of the cavity 40 is set to be in a range of 0.2 cm to 1.8 cm, so as to ensure the noise reduction effect of the cavity 40.

In one embodiment, as shown in fig. 4, the reinforcing plate 30 includes a connecting portion 33 closely attached to the face shell 20, and the connecting portion 33 is formed by bending the protruding portion 31 toward the face shell 20.

The connection between the connection portion 33 and the face case 20 is performed by bonding, welding, or bolting.

In one embodiment, as shown in fig. 4, the width of the connecting portion 33 is not less than 0.2 cm and not more than 3 cm.

It can be understood that if the width of the connection portion 33 is less than 0.2 cm, the connection strength between the reinforcing plate 30 and the face shell 20 is insufficient, which does not play a role of reinforcing the face shell 20, and may also cause the face shell 20 to vibrate, increasing noise; if the width of the connecting portion 33 is larger than 3 cm, the size of the convex portion 31 is reduced, the area of the cavity 40 is reduced, and the noise reduction effect of the cavity 40 is reduced. Therefore, the width of the connecting portion 33 is set to a range of 0.2 cm to 3 cm.

In an embodiment, as shown in fig. 4, the connecting portion 33 includes a first connecting portion 331 and a second connecting portion 332, the first connecting portion 331 is an outer edge of the reinforcing plate 30, and the second connecting portion 332 is disposed at an inner edge of the avoiding portion.
