Description

Technical Field

[0001] The utility model relates to the technical field of water heaters, in particular to a water heater housing. Background Art

[0002] During the operation of a gas water heater, noise will be generated. The noise of the gas water heater mainly comes from the vibration of the internal fan and combustion. There are mainly two ways of transmitting this vibration. One is through the air in the air inlet channel, and the other is that the sound source drives the housing to vibrate, causing the air near the water heater to vibrate and thus spread to the outside of the water heater. Moreover, the former will also drive the housing to vibrate to a certain extent. Therefore, reducing the housing vibration can also reduce the noise of the water heater during operation to a certain extent.

[0003] In the prior art, in order to reduce the housing vibration, the common practice is to increase the overall thickness of the housing to increase the overall weight of the housing, which can reduce part of the vibration to a certain extent. However, the above method not only greatly increases the manufacturing cost of the water heater, but also greatly increases the weight of the water heater, resulting in an increase in transportation cost. Summary of the Utility Model

[0004] The technical problem solved by the utility model is to provide a water heater housing to solve the problem that in the prior art, in order to reduce the vibration of the water heater housing, the weight and cost of the water heater are greatly increased; while reducing the vibration of the water heater housing and reducing the noise of the water heater, the cost is reduced.

[0008] The water heater housing of the utility model, compared with the background art, has the beneficial effects as follows:

[0009] The water heater shell provided by the utility model is used to support the first side plate, the second side plate and the front shell of the bottom shell by arranging at least one support frame between the bottom shell and the front shell. Since the first side plate and the second side plate arranged relatively to the bottom shell are easy to generate a large amplitude when subjected to vibration excitation, and vibrate in a direction perpendicular to the first side plate and the second side plate, the first side plate and the second side plate are connected by connecting the two ends of the support frame, which can greatly increase the structural strength of the first side plate and the second side plate, thereby reducing the vibration amplitude and reducing the occurrence of resonance. The water heater shell provided by the utility model increases the strength of the bottom shell and the front shell by the support frame, thereby reducing the vibration amplitude of the water heater shell during the operation of the water heater, so as to achieve the purpose of reducing the noise when the water heater is working. Compared with the prior art, the utility model increases the structural strength of the first side plate and the second side plate by arranging the support frame connected to the first side plate and the second side plate. Compared with the weight increase caused by the increase in the overall thickness of the water heater shell in the prior art, the overall weight increase of the water heater shell of the utility model is less, so the manufacturing cost and transportation cost are both less increased.

[0011] In one embodiment, the support frame further includes a first reinforcement structure, and the first reinforcement structure is arranged at intervals along the extension direction of the support frame.

[0034] In the description of the present application, it should be noted that unless otherwise clearly defined and limited, the term "connection" 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 directly connected, or indirectly connected through an intermediate medium, and it may be the internal communication of two elements. For those of ordinary skill in the art, the specific meaning of the above terms in the present application can be understood according to specific situations.

[0035] Such as Figure 1As shown in the figure, this embodiment provides a water heater housing, which includes a bottom case 1 and a front case 2. The front case 2 is detachably connected to the front side of the bottom case 1. The bottom case 1 includes a bottom plate, a first side plate 11 and a second side plate 12 oppositely arranged in the width direction, and a first end plate 14 and a second end plate 15 oppositely arranged in the length direction. A receiving cavity is formed inside the bottom case 1, and components such as a water pump and a water-gas linkage valve are accommodated in the receiving cavity. The front case 2 includes a panel 21 and bending plates 22. There are two bending plates 22, and the two bending plates 22 are respectively arranged on both sides of the panel 21. The bending plates 22 are bent from one side of the panel 21 towards the direction close to the bottom case 1, and the two bending plates 22 are respectively butted against the first side plate 11 and the second side plate 12 to close the opening of the bottom case 1. The connection surfaces between the two bending plates 22 and the panel 21 are both arc-shaped surfaces. The first end plate 14 and the second end plate 15 are respectively connected to the two ends of the panel 21 by means of screws or the like.

[0036] During the operation of the water heater, the first side plate 11, the second side plate 12 and the panel 21 are easily excited by vibration to generate a relatively large amplitude, and the vibration of the water heater housing will cause a relatively large noise in the water heater.

[0037] The water heater housing provided in this embodiment reduces the vibration of the water heater housing and reduces the noise during the operation of the water heater. As Figure 1 and Figure 2 shown in the figure, the water heater housing further includes at least one support frame 3. The support frame 3 is arranged between the bottom case 1 and the front case 2, and the two ends of the support frame 3 are respectively connected to the first side plate 11 and the second side plate 12. Since the first side plate 11 and the second side plate 12 of the bottom case 1 oppositely arranged are easily excited by vibration to generate a relatively large amplitude and vibrate in the direction perpendicular to the first side plate 11 and the second side plate 12, by connecting the first side plate 11 and the second side plate 12 at both ends of the support frame 3, the structural strength of the first side plate 11 and the second side plate 12 can be greatly increased, thereby reducing the vibration amplitude and reducing the occurrence of resonance. Compared with the prior art, the water heater housing provided in this embodiment is provided with a support frame 3 connected to the first side plate 11 and the second side plate 12 to increase the structural strength of the first side plate 11 and the second side plate 12. Compared with the increase in weight caused by the increase in the overall thickness of the housing in the prior art, the overall weight of the water heater housing provided in this embodiment increases less, so the manufacturing cost and transportation cost both increase less.

[0038] In one embodiment, the support frame 3 includes a first connecting portion and a second connecting portion. The first connecting portions are located at both ends of the support frame 3, and the two first connecting portions are respectively connected to the first side plate 11 and the second side plate 12. The second connecting portion protrudes between the two first connecting portions and elastically presses against the inner wall of the front shell 2. By elastically pressing the second connecting portion protruding between the two first connecting portions against the inner wall of the front shell 2, while supporting the front shell 2 to increase the strength of the front shell 2, the stress surface between the support frame 3 and the front shell 2 is increased, so that the force between the support frame 3 and the front shell 2 is more uniform, and at the same time, the vibration amplitude of the front shell 2 is reduced. Further reduce the vibration amplitude of the water heater shell during the operation of the water heater, so as to achieve the purpose of reducing the noise during the operation of the water heater, and at the same time, the manufacturing cost and transportation cost will not be increased.

[0039] Of course, in other embodiments, the support frame 3 can also be set as an arc-shaped frame. The two ends of the arc-shaped frame are respectively connected to the first side plate 11 and the second side plate 12, and the vertex of the arc-shaped frame elastically presses against the inner wall of the front shell 2.

[0040] In one embodiment, the number of the support frames 3 is set according to the lengths of the first side plate 11 and the second side plate 12. When the lengths of the first side plate 11 and the second side plate 12 are longer, the number of the support frames 3 is set to be more. Exemplarily, three support frames 3 are provided, and the three support frames 3 are arranged at intervals along the length directions of the first side plate 11 and the second side plate 12 to ensure the uniformity of the structural strength of the first side plate 11, the second side plate 12 and the front shell 2, so that the bottom shell 1 and the front shell 2 are stressed evenly, and the service life is prevented from being shortened due to uneven stress. When the lengths of the first side plate 11 and the second side plate 12 are shorter, one or two support frames 3 are provided.

[0041] In one embodiment, as Figures 1-3 shown, extension plates 13 are provided on the inner walls of both the first side plate 11 and the second side plate 12. The extension plates 13 are perpendicular to the first side plate 11 and the second side plate 12. The first connecting portion includes a connecting plate 31 arranged parallel to the extension plate 13, and the extension plate 13 and the connecting plate 31 are fixedly connected. A connecting hole 311 is provided on the connecting plate 31, and a threaded hole 131 is provided on the extension plate 13. After the extension plate 13 and the connecting plate 31 are attached, a fastening screw 5 passes through the connecting hole 311 and is screwed with the threaded hole 131, so as to fixedly connect both ends of the support frame 3 to the first side plate 11 and the second side plate 12 respectively. In other embodiments, a clamping protrusion and a clamping groove can also be correspondingly provided on the connecting plate 31 and the extension plate 13, and both ends of the support frame 3 are fixedly connected to the first side plate 11 and the second side plate 12 respectively by means of clamping cooperation between the clamping protrusion and the clamping groove.

[0042] In one embodiment, the second connecting portion includes an abutting plate 32. Since the connecting surface between the panel 21 and the bending plate 22 is an arc surface, in order to prevent the support frame 3 from interfering with the surface shell 2, the abutting plate 32 protrudes from the connecting plates 31 at both ends so that the abutting plate 32 can abut against the panel 21.

[0043] In one embodiment, the support frame 3 is integrally die-cast from galvanized steel sheet or cold-rolled sheet, which ensures the support strength of the support frame 3, further improves the structural strength of the bottom shell 1 and the surface shell 2, and thus reduces the vibration of the water heater shell.

[0044] In one embodiment, the water heater shell further includes a buffer member 4. The second connecting portion is elastically pressed against the inner wall of the surface shell 2 through the buffer member 4. The buffer member 4 is adhesively fixed to the abutting plate 32. After the surface shell 2 and the bottom shell 1 are fixedly connected, the buffer member 4 is in a compressed state. This can increase the force-bearing area between the abutting plate 32 and the panel 21, make the force between the abutting plate 32 and the panel 21 more uniform, and at the same time, the buffer member 4 has the function of damping and buffering, reducing the vibration amplitude of the surface shell 2. The buffer member 4 can be made of materials with good damping performance such as rubber.

[0045] In addition, on the one hand, since both the surface shell 2 and the support frame 3 are metal parts with poor deformation ability, the direct abutment between the abutting plate 32 and the panel 21 may cause irreversible deformation of the surface shell 2; on the other hand, due to the existence of errors in the processing and manufacturing process, it is difficult to ensure that the abutting plate 32 and the panel 21 are completely fitted. By providing the buffer member 4 between the abutting plate 32 and the panel 21, on the one hand, it can prevent the surface shell 2 from deforming, and on the other hand, it can ensure that the abutting plate 32 and the panel 21 are completely fitted and the force is more uniform.

[0046] Of course, in other embodiments, a buffer member 4 such as a spring or a shock pad can also be provided between the abutting plate 32 and the panel 21, and the elastic force of the spring or the shock pad is used to realize the elastic abutment between the support frame 3 and the surface shell 2, so that the support frame 3 can not only support the surface shell 2, but also buffer the vibration force received by the surface shell 2.

[0047] In one embodiment, as Figure 3 and Figure 4As shown, the support frame 3 further includes an engaging portion for connecting the first connecting portion and the second connecting portion. The connection between the first connecting portion and the engaging portion, as well as the connection between the engaging portion and the second connecting portion, are both stepped connections. The engaging portion includes an engaging plate 33. The length of the abutting plate 32 is set corresponding to the width of the panel 21, and the length of the connecting plate 31 is set corresponding to the width of the extending plate 13. The engaging plate 33 is arranged corresponding to the arc surface at the connection of the panel 21 and the bending plate 22. To avoid interference between the support frame 3 and the arc surface, the engaging plate 33 should be arranged below the arc surface. The abutting plate 32, the engaging plate 33, and the connecting plate 31 are arranged in sequence from the direction close to the face shell 2 to the direction close to the bottom shell 1, and are located at different height positions. One end of the abutting plate 32 and the engaging plate 33 is connected by a first vertical plate 34, and the other end of the engaging plate 33 is connected to the connecting plate 31 by a second vertical plate 35. The connection between the first vertical plate 34 and one end of the engaging plate 33 is a stepped connection, defined as the first step; the connection between the other end of the engaging plate 33 and the second vertical plate 35 is also a stepped connection, defined as the second step. The connection between the second vertical plate 35 and the connecting plate 31 is also a stepped connection, defined as the third step.

[0048] In one embodiment, the support frame 3 further includes a first strengthening structure, which is arranged at intervals along the extending direction of the support frame 3. By arranging the first strengthening structure at intervals along the extending direction of the support frame 3, the anti-deformation ability of the support frame 3 in the extending direction can be increased. Thus, when the first side plate 11 and the second side plate 12 are vibrated in a direction perpendicular to the first side plate 11 and the second side plate 12, the support frame 3 will not be deformed due to the vibration, better support the first side plate 11 and the second side plate 12, and reduce the vibration of the first side plate 11 and the second side plate 12.

[0049] In one embodiment, the first strengthening structure is arranged at the stepped connection. The first strengthening structure is provided at both the first step and the second step.

[0050] In one embodiment, the first strengthening structure includes a rib 36. By adding ribs 36 at the first step and the second step, the strength of the first step and the second step is increased by using the ribs 36, avoiding the generation of acting forces in opposite directions along the extending direction on the support frame 3 when the first side plate 11 and the second side plate 12 vibrate, resulting in fractures at the first step and the second step.

[0051] In other embodiments, the first strengthening structure can also include other strengthening structures such as increasing the thickness of the first step and the second step.

[0052] In one embodiment, the support frame 3 includes a second reinforcement structure, which is connected to the side of the second connection portion facing away from the face shell 2 and is perpendicular to the side of the second connection portion facing away from the face shell 2. By providing the second reinforcement structure, the anti-deformation ability of the support frame 3 when subjected to a force perpendicular to the extension direction of the support frame 3 is increased, the panel 21 is better supported, and the vibration of the panel 21 is reduced.

[0053] In one embodiment, the second reinforcement structure includes a flange 37, which is connected to the side of the abutment plate 32 facing away from the face shell 2 and is perpendicular to the side of the abutment plate 32 facing away from the face shell 2. When the face shell 2 is subjected to a vibration force perpendicular to the direction of the panel 21, the vibration force will be transmitted to the abutment plate 32 of the support frame 3. In order to increase the strength of the abutment plate 32, a flange 37 perpendicular to the abutment plate 32 is provided on the abutment plate 32. The flange 37 can increase the anti-deformation ability of the abutment plate 32, can provide more powerful support for the panel 21, and reduce the vibration of the panel 21.

[0054] In one embodiment, the first reinforcement structure and the second reinforcement structure are both triangular ribs. The first reinforcement structure and the second reinforcement structure are set to have the same structure that has both anti-deformation ability along the extension direction of the support frame 3 and anti-deformation ability perpendicular to the extension direction of the support frame 3, such as triangular ribs, and the triangular ribs are set at the first step and the third step. One right-angled side of the triangular rib located at the first step is connected to the first vertical plate 34, and the other right-angled side is connected to the connecting plate 33; one right-angled side of the triangular rib located at the third step is connected to the second vertical plate 35, and the other right-angled side is connected to the connecting plate 31. In this way, a total of four triangular ribs are set along the extension direction of the support frame 3, and the four triangular ribs work together to increase the anti-deformation ability of the support frame 3 in the extension direction. For the triangular ribs located at the first step and the third step, since they are located at different heights of the support frame 3 perpendicular to its extension direction, the anti-deformation ability perpendicular to the extension direction of the support frame 3 can be increased.

[0055] By arranging the first reinforcing structure and the second reinforcing structure on the support frame 3, the deformation resistance of the support frame 3 when subjected to force along the extension direction and perpendicular to the extension direction is improved at the same time, the overall strength of the support frame 3 is strengthened, and the supporting strength of the bottom shell 1 and the surface shell 2 is improved, which can reduce the vibration of the water heater shell and further reduce the noise of the water heater shell.

[0056] In the specific contents of the above-mentioned specific implementation methods, the various technical features can be combined in any non-contradictory manner. In order to make the description concise, not all possible combinations of the above-mentioned technical features are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0057] The specific content of the above specific embodiments only expresses several embodiments of the present utility model, and its description is relatively specific and detailed. However, it should not be construed as a limitation on the scope of the patent for 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 for the present utility model shall be subject to the appended claims.
