Description

Technical Field

[0001] The utility model relates to the technical field of noise reduction of household appliances, in particular to a noise reduction housing and a gas water heater. Background Art

[0002] Due to its excellent performance, gas water heaters have gradually entered thousands of households. Gas water heaters are usually installed on the wall in a wall-mounted manner, which is small and convenient and does not occupy limited spaces such as kitchens.

[0003] Since components that are prone to generate noise, such as a blower and a water pump, are usually configured inside a gas water heater, during the operation of the gas water heater, noise is likely to leak from the connection between the front panel and the side panel, resulting in a poor user experience.

[0004] In order to reduce the leakage noise at the connection between the front panel and the side panel, a foam, such as EVA foam (ethylene-vinyl acetate copolymer), is installed at the connection between the front panel and the side panel of the housing of the existing gas water heater. However, the sound insulation effect of EVA foam is poor, and there are gaps at the connections between the EVA foam and the front panel and the side panel, and noise is likely to diffract from the gaps, so the noise reduction effect is not good and the user experience is poor. Summary of the Utility Model

[0005] The first technical problem solved by the utility model is to provide a noise reduction housing, which effectively solves the problem that noise of the existing gas water heater is likely to leak from the connection between the front panel and the side panel, affecting the user experience. A sealing ring is clamped between the first flanging of the front panel and the second flanging of the side panel of the noise reduction housing, which can significantly reduce the noise leaking from the front panel and the side panel during the operation of the gas water heater, and the user experience is good.

[0006] The second technical problem solved by the utility model is to provide a gas water heater, which effectively solves the problem that noise of the existing gas water heater is likely to leak from the connection between the front panel and the side panel, affecting the user experience. A sealing ring is clamped between the first flanging of the front panel and the second flanging of the side panel of the noise reduction housing, which can significantly reduce the noise leaking from the front panel and the side panel during the operation of the gas water heater, and the user experience is good.

The panel is provided with the first flanging, and the side plate is provided with the second flanging. On the one hand, it can increase the contact area between the panel and the side plate, improve the sealing performance of the connection between the panel and the side plate, and on the other hand, it can also fix the sealing ring, simplify the fixing structure of the sealing ring, and reduce the use cost.

[0035] In the description of the present application, it should be noted that unless otherwise clearly defined and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or an integral connection; it may be a mechanical connection or an electrical connection; it may be directly connected, or indirectly connected through an intermediate medium, and it may be the communication inside two elements.

[0036] Existing gas water heaters generally stamp fixed flanges on the side plates, and squeeze strip-shaped EVA cotton into the fixed flanges through the panel to achieve the sealing between the panel and the side plate. However, this installation method requires stamping fixed flanges on the side plates in advance, with a relatively high manufacturing process difficulty and manufacturing cost. Due to the poor elasticity and small density of EVA cotton, the sealing effect decays and the sound insulation ability decreases after multiple squeezes (such as maintenance). In addition, EVA cotton cannot completely fill the connection between the panel and the side plate, and there are inevitably gaps, and noise is also likely to leak from the gaps. Therefore, the noise reduction effect is poor and the user experience is not good.

[0037] Next, in combination with Figures 1 to 7 , the embodiments of the present invention will be described.

[0038] According to the embodiments of the present invention, on the one hand, as Figure 1As shown, a noise reduction housing is provided, mainly including a panel 1, side plates 2 and a sealing ring 3.

[0039] The noise reduction housing described in this embodiment is mainly used for gas water heating equipment. The noise reduction housing is used to cover various components inside the gas water heating equipment. On the one hand, it provides an installation space. On the other hand, it reduces the noise leakage at the connection between the panel 1 and the side plates 2 of the gas water heating equipment, improving the sound insulation effect of the gas water heating equipment.

[0040] It should be noted that the gas water heating equipment described in the embodiments of this application includes, but is not limited to, equipment such as gas water heaters and wall-mounted boilers that use gas combustion to provide hot water.

[0041] Furthermore, as Figure 1 and Figure 2 shown, the side plates 2 surround the panel 1. The four sides of the panel 1 are recessed inward to form a first flanging 4, and the four sides of the side plates 2 are recessed inward to form a second flanging 5. The sealing ring 3 is clamped between the first flanging 4 and the second flanging 5.

[0042] It can be seen that for the noise reduction housing provided in the embodiments of this application, the sealing ring 3 is clamped by the first flanging 4 around the panel 1 and the second flanging 5 around the side plates 2. When the gas water heating equipment is operating, the sealing ring 3 can seal the first flanging 4 and the second flanging 5, blocking the gap at the connection between the panel 1 and the side plates 2 and reducing the leakage noise at the connection between the panel 1 and the side plates 2. The panel 1 is provided with the first flanging 4, and the side plates 2 are provided with the second flanging 5. On the one hand, it can increase the contact area between the panel 1 and the side plates 2, improving the sealing performance of the connection between the panel 1 and the side plates 2. On the other hand, it can also fix the sealing ring 3, simplifying the fixing structure of the sealing ring 3 and reducing the use cost.

[0043] Moreover, the sealing ring 3 is an integral sealing structure, which is easier to install compared to traditional strip-shaped EVA cotton, and can expand the sealing area, reducing the gap at the connection between the panel 1 and the side plates 2, with a better sound insulation effect.

[0044] It should be noted that the inner and outer directions mentioned in the embodiments of this application are as Figure 3 and Figure 5 shown.

[0045] In one embodiment, as Figure 7 shown, the sealing ring 3 is provided with slots 301 with the slots opening outward around its perimeter. The slots 301 are inserted into the first flanging 4 or the second flanging 5, and one side wall of the slots 301 is clamped between the first flanging 4 and the second flanging 5. In the embodiments of this application, the sealing ring 3 is clamped and fixed by the cooperation of the slots 301 with the first flanging 4 and the second flanging 5. Compared with the traditional stamping flanging structure, the process difficulty is reduced, the materials for the stamping part are saved, and the manufacturing cost is relatively low.

[0046] Exemplarily, asFigure 7 As shown, the slot 301 is inserted into the second flanging 5, and the side wall of the slot 301 close to the panel 1 is clamped between the first flanging 4 and the second flanging 5. In order to improve the connection stability between the sealing ring 3 and the first flanging 4 or the second flanging 5, at least one side of the sealing ring 3 can also be bonded to the first flanging 4 or the second flanging 5 through fixing glue.

[0047] Furthermore, in one embodiment, as Figure 7 shown, the width dimension of the slot 301 gradually expands from the slot opening inward, and the width of the slot opening of the slot 301 is less than or equal to the thickness of the second flanging 5, so as to form a squeezing force at the slot opening, so that the second flanging 5 is clamped in the slot 301. In addition, the thickness of the sealing ring 3 is less than or equal to the distance between the first flanging 4 and the second flanging 5, so that the sealing ring 3 is clamped between the first flanging 4 and the second flanging 5.

[0048] It should be noted that the panel 1 is fixedly connected to the side plate 2 to clamp the sealing ring 3. The embodiment of the present application does not limit the fixed connection method between the panel 1 and the side plate 2. It can be a snap-fit fixed structure for quick installation, or it can be set as a fastener-type fixed structure with firm connection.

[0049] In one embodiment, as Figures 1 to 3 shown, a pair of lugs 201 extending toward the panel 1 are respectively provided at the top and bottom of the side plate 2, and the pair of lugs 201 are respectively fixedly connected to the panel 1 through fasteners 202. Compared with the snap-fit fixed structure, the fastener-type fixed structure is more firm and is conducive to improving the connection stability between the panel 1 and the side plate 2.

[0050] Specifically, the fasteners 202 can adopt conventional fasteners such as screws and bolts. Threaded holes or round holes are correspondingly provided on the lugs 201 and the panel 1. By passing the fasteners 202 through the threaded holes or round holes on the lugs 201 and the panel 1 respectively, the lugs 201 are fixedly connected to the panel 1, that is, the side plate 2 is fixedly connected to the panel 1. The structure is simple, the installation is convenient, and the use cost is low, further improving the connection stability between the side plate 2 and the panel 1.

[0051] In addition, the lugs 201 can be formed by cutting a part of the second flanging 5 and bending it toward the side plate 2, so as to reduce the processing difficulty of the lugs 201 and further reduce the manufacturing cost.

[0052] Furthermore, in one embodiment, the outer side surface of the lug 201 is in close contact with the inner side surface of the panel 1, and the first flanging 4 is provided with an avoidance groove 401 for avoiding the lug 201. The fastener 202 passes through the top surface of the panel 1 and is connected to the lug 201, so that the lug 201 is hidden inside the panel 1, avoiding the lug 201 from affecting the flatness of the surface of the panel 1 and having a beautiful appearance.

[0053] Furthermore, in one embodiment, the lug 201 is disposed outside the sealing ring 3. The fastener 202 fixes the lug 201 and the panel 1 without affecting the sealing effect of the sealing ring 3, which can prevent noise from leaking from the fixed connection between the side plate 2 and the panel 1, and further improve the sound insulation effect.

[0054] In some other embodiments, the outer side surface of the lug 201 can also be closely attached to the inner side surface of the panel 1 through fixing glue.

[0055] In one embodiment, as Figure 2 shown, the panel 1 includes a bottom plate 101 and a third flanging 102 surrounding the periphery of the bottom plate 101. The peripheral side of the third flanging 102 extends towards the side plate 2 and is connected to the first flanging 4. By providing the third flanging 102, it is convenient to install the first flanging 4.

[0056] In one embodiment, as Figure 2 and Figure 4 shown, the side plate 2 includes an upper side plate, a lower side plate and a pair of sub - side plates. The upper side plate and the lower side plate are arranged oppositely. The opposite sides of the upper side plate are respectively connected to the tops of the pair of sub - side plates. Similarly, the opposite sides of the lower side plate are respectively connected to the bottoms of the pair of sub - side plates. The connection method can be selected as plug - in connection.

[0057] In one embodiment, as Figure 4 shown, the noise - reducing housing further includes a back plate 6. The periphery of the back plate 6 is detachably connected to the side plate 2. The back plate 6, the side plate 2 and the panel 1 together form a closed housing to accommodate various components of the gas water heating device. The detachable installation form can adopt any existing structure, such as snap - fit connection for quick installation, or fastener connection to improve the connection tightness. An air inlet is provided at the upper end of the back plate 6 to introduce external air into the interior of the noise - reducing housing.

[0058] Furthermore, in one embodiment, as Figure 2 and Figure 4 shown, a mounting bracket 7 is also fixedly provided on one side of the upper side plate close to the back plate 6, and a mounting bracket 7 is also fixedly provided on one side of the lower side plate close to the back plate 6. The noise - reducing housing is fixed to the wall through a pair of mounting brackets 7.

[0059] Specifically, the opposite sides of the back plate 6 are integrally formed with a pair of sub-side plates respectively for easy installation and use. The upper end of the back plate 6 is fixedly connected to the upper side plate and the mounting bracket 7 respectively through fasteners, and the lower end of the back plate 6 is fixedly connected to the lower side plate and the mounting bracket 7 respectively through fasteners to improve the connection stability and reduce the number of mounting points. The fasteners can be conventional fasteners such as screws and bolts. Correspondingly, the upper side plate, the lower side plate, the mounting bracket 7 and the back plate 6 are respectively provided with threaded holes or round holes. The upper side plate and the lower side plate are respectively inserted into a pair of sub-side plates. The mounting bracket 7 extends a flange along the width direction of the back plate 6, and a plurality of mounting holes are provided on the flange. The mounting bracket 7 is fixed to the wall through the mounting holes.

[0060] Further, in one embodiment, the panel 1 is integrally formed with the first flange 4, and the side plate 2 is integrally formed with the second flange 5. Specifically, the third flange 102 of the panel 1 is bent inward to form the first flange 4, and the upper side plate, the lower side plate and a pair of sub-side plates are bent inward respectively and jointly form the second flange 5. By integrally forming the panel 1 with the first flange 4 and the side plate 2 with the second flange 5, it is possible to prevent noise from leaking from the connection between the panel 1 and the first flange 4 and the connection between the side plate 2 and the second flange 5, improve the sound insulation effect, and further enhance the user experience.

[0061] It should be noted that the material of the sealing ring 3 is not limited in the embodiments of the present application, and any existing material can be selected according to needs. In one embodiment, in order to improve the sealing effect, the sealing ring 3 is a silicone gasket. The silicone gasket has good elasticity, still has a good sealing effect after multiple disassembly and assembly, has a long service life, and also has a better sound insulation effect than EVA cotton. In addition, the silicone gasket can be made into a dark color, such as black, which can prevent the light inside the noise reduction housing from transmitting through the silicone gasket to form light leakage compared with the traditional white silicone gasket.

[0062] In some other embodiments, the material of the sealing ring 3 can also be selected from other conventional materials according to needs.

[0063] According to an embodiment of the present invention, on the other hand, a gas water heating device is also provided, including: a noise reduction housing.

[0064] The gas water heating device of the embodiments of the present application has the noise reduction housing, and the panel 1 and the side plate 2 are provided with the first flange 4 and the second flange 5, and cooperate with the sealing ring 3, which can reduce the leakage noise at the connection between the panel 1 and the side plate 2. Compared with the existing gas water heating devices, the noise is smaller, it has a good sound insulation effect, and the user experience is better.

[0065] To implement the basic functions of the gas water heating equipment, the gas water heating equipment in the embodiments of the present application may further include other necessary modules or components, such as a blower, a water pump, etc. It should be noted that the other necessary modules or components included in the gas water heating equipment can be any suitable existing structures. For the sake of clearly and briefly explaining the technical solutions provided by the embodiments of the present application, the above parts will not be elaborated herein, and the accompanying drawings of the specification have also been correspondingly simplified. However, it should be understood that the scope of the present utility model is not limited thereby.

[0066] In the specific content of the above specific implementation manners, the technical features can be combined arbitrarily without contradiction. For the sake of concise description, not all possible combinations of the above technical features are described. However, as long as the combinations of these technical features do not exist in contradiction, they should all be considered as the scope recorded in this specification.

[0067] The specific content of the above specific implementation manners only expresses several implementation manners of the present utility model. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several deformations and improvements can still be made, and these all belong to the protection scope of the present utility model. Therefore, the protection scope of the patent of the present utility model shall be subject to the appended claims.
