[0034] Combine the following Figures 1 to 7 , describing an embodiment of the utility model.

[0035] According to an embodiment of the present utility model, on the one hand, as Figure 1 As shown, a noise reduction shell is provided, which mainly includes a panel 1, a side panel 2 and a sealing strip 3.

[0036] The noise reduction housing mentioned in this embodiment is mainly used for gas water heaters. The noise reduction housing is used to cover various components inside the gas water heater, on the one hand to provide installation space, on the other hand to reduce the noise leaked from the connection between the panel 1 and the side panel 2 of the gas water heater, and improve the sound insulation effect of the gas water heater.

[0037] It should be noted that the gas water heating equipment mentioned in this embodiment includes but is not limited to gas water heaters, wall-mounted boilers and other equipment that utilizes gas combustion to provide hot water.

[0038] Furthermore, if Figure 1 and Figure 2 As shown, the side panel 2 is arranged around the panel 1. The panel 1 is provided with a first enclosure 4 extending toward the side panel 2. The side panel 2 is provided with a second enclosure 5 extending toward the panel 1. The first enclosure 4 is in contact with the second enclosure 5. The sealing strip 3 is attached and covered at the contact between the first enclosure 4 and the second enclosure 5.

[0039] It can be seen that the noise reduction shell provided in the embodiment of the present application increases the contact area between the panel 1 and the side panel 2 by abutting the first enclosure 4 around the panel 1 with the second enclosure 5 around the side panel 2, improves the sealing of the connection between the panel 1 and the side panel 2, and seals the abutment between the first enclosure 4 and the second enclosure 5 by the sealing strip 3. When the gas water heater is in operation, the first enclosure 4 and the second enclosure 5 can preliminarily close the connection between the panel 1 and the side panel 2, reducing noise leakage from the connection between the panel 1 and the side panel 2. The sealing strip 3 is attached and coated on the abutment between the first enclosure 4 and the second enclosure 5, which can further close the abutment between the first enclosure 4 and the second enclosure 5, further reducing noise leakage from the abutment between the first enclosure 4 and the second enclosure 5, thereby improving the sound insulation effect of the noise reduction shell and providing a better user experience.

[0040] In one embodiment, Figure 3 and Figure 5 As shown, the first enclosure 4 includes a first step portion 401 and a first connecting portion 402 connected in sequence, and the first step portion 401 extends along the inner side of the panel 1. The second enclosure 5 includes a second step portion 501 and a second connecting portion 502 connected in sequence, and the second step portion 501 extends along the inner side of the panel 1. The first connecting portion 402 abuts against the second connecting portion 502 so that the first step portion 401, the first connecting portion 402, the second connecting portion 502 and the second step portion 501 form a sealing groove. The sealing strip 3 is embedded in the sealing groove.

[0041] The first connection part 402 is abutted against the second connection part 502 to increase the contact area between the panel 1 and the side panel 2, thereby improving the sealing performance of the connection between the panel 1 and the side panel 2. The first step part 401, the first connection part 402, the second connection part 502 and the second step part 501 are used to form a sealing groove for installing the sealing strip 3, and no other installation parts are required, so that noise leakage from the installation parts can be avoided, and good sound insulation effect is achieved.

[0042] It should be noted that the inner and outer directions in the embodiments of the present application are as follows: Figure 3 shown.

[0043] Exemplarily, the panel 1, the first step portion 401 and the first connecting portion 402 are integrally formed. The side panel 2, the second step portion 501 and the second connecting portion 502 are also integrally formed. Specifically, the four sides of the panel 1 are first bent inward to form the first step portion 401, and then bent toward the side panel 2 to form the first connecting portion 402. Similarly, the four sides of the side panel 2 are first bent inward to form the second step portion 501, and then bent toward the panel 1 to form the second connecting portion 502, which is convenient for manufacturing and processing.

[0044] Further, in one embodiment, if Figure 1 and Figure 7 As shown, the sealing strip 3 is clamped between the first step portion 401 and the second step portion 501, so that the inner side of the sealing strip 3 covers the outer side of the first connection portion 402 and the second connection portion 502. By clamping the sealing strip 3 with the first step portion 401 and the second step portion 501, the sealing strip 3 can be fixed to prevent the sealing strip 3 from falling off, thereby improving the installation stability of the sealing strip 3. The outer side of the sealing strip 3 can be aligned with the outer side of the side panel 2 to prevent the sealing strip 3 from being worn, thereby improving its service life.

[0050] Further, in one embodiment, the outer side of the ear 8 is in close contact with the inner side of the first connecting portion 402. The third step portion 6 is provided with an avoidance groove 9 for avoiding the ear 8. The ear 8 passes through the avoidance groove 9 and abuts against the first enclosure 4. That is, the outer side of the first enclosure 4 is the sealing strip 3, and the inner side of the first enclosure 4 is the ear 8, which is convenient for installing the sealing strip 3, and the ear 8 is hidden inside the first enclosure 4, and the appearance is beautiful.

[0051] Furthermore, in one embodiment, a fastener is installed on the inner side of the sealing groove so that the sealing strip 3 can seal the connection between the support ear 8 and the first enclosure 4, thereby preventing noise from leaking from the connection between the support ear 8 and the first enclosure 4 and further improving the sound insulation effect.

[0052] In one embodiment, Figure 2 As shown, the panel 1 includes a bottom plate 101 and flanges 102 arranged around the bottom plate 101, and the flanges 102 extend toward the side plates 2 and are connected to the first enclosure 4.
