Description

Technical Field

[0001] The present invention relates to the technical field of household electrical appliances, and in particular to hot water treatment equipment. Background Art

[0002] In related technologies, gas water heaters need to draw air through the air intake duct to participate in combustion during the heating process, and the air intake duct also becomes the main channel for combustion noise to radiate outward. At the same time, most traditional gas water heaters adopt a back air intake design, and the air inlet is located close to the combustion element. The combustion noise can be directly radiated from the air inlet to the outside of the water heater, and the radiated noise is large, which in turn affects the customer's usage experience. Summary of the Invention

[0003] The present invention aims to solve at least one of the technical problems existing in the prior art or related art.

[0004] To this end, one object of the present invention is to provide a hot water treatment device.

[0005] In view of this, a hot water treatment device is proposed according to the present invention, which includes: a first shell, the first shell includes an installation cavity and an air inlet; a second shell, the second shell is connected to the first shell, the second shell is located in the installation cavity, and the second shell includes a vent; wherein the second shell and the first shell form a silencer cavity, the air inlet is connected to the silencer cavity, and the vent is connected to the silencer cavity and the installation cavity.

[0006] The hot water treatment device provided by the present invention includes a first shell and a second shell connected to the first shell. The first shell includes an installation cavity and an air inlet, the second shell includes a vent, the second shell and the first shell enclose a silencer cavity, the air inlet is connected to the silencer cavity, the vent is connected to the silencer cavity and the installation cavity, and the air inlet, the vent and the silencer cavity are connected. The hot water treatment device provided by the present application is formed by a first shell with an air inlet and a second shell with a vent to enclose a silencer cavity, the installation cavity and the silencer cavity are separated, so that the entire shell assembly is formed with two air inlets, that is, during the air intake process, the air flow enters the silencer cavity from the air inlet and then enters the installation cavity through the vent. During the operation of the hot water treatment device, noise enters the silencer cavity through the vent and then can be radiated to the outside through the air inlet. The arrangement of the vent, the silencer cavity and the air inlet greatly extends the radiation path of the generated noise during the radiation process to the outside, and the noise radiated to the outside is greatly attenuated, so as to achieve the purpose of reducing noise and improving user comfort.

[0007] In addition, the hot water treatment equipment in the above technical solution provided by the present invention may also have the following additional technical features:

[0008] In the above technical solution, the hot water treatment equipment further includes: a partition, which is arranged on the first shell and located in the silencer cavity, and the partition is arranged opposite to the air inlet.

[0009] In this technical solution, the hot water treatment equipment also includes a baffle mounted on the first housing, located within the silencing chamber, and positioned opposite the air inlet. This allows air flowing in through the air inlet to be blocked by the baffle, which then flows along the baffle into the vent, thereby providing a diversion mechanism. Furthermore, noise entering the silencing chamber from the vent is radiated to the baffle, which in turn blocks some of the noise from escaping through the air inlet. This significantly extends the radiation path of the generated noise as it radiates to the outside world, significantly attenuating the noise radiated to the outside world and achieving the desired noise reduction.

[0010] In any of the above technical solutions, the first shell includes: a cover body, the air inlet is arranged on the cover body, and the partition is connected to the cover body; a main body, the cover body is connected to the main body to form an installation cavity; wherein the second shell is connected to the cover body or the main body.

[0011] In this technical solution, the first shell includes a cover plate and a main body, wherein the air inlet is arranged on the cover plate, and the partition is connected to the cover plate, so that the air inlet is located on the upper part of the hot water treatment equipment, thereby performing top plate ventilation. During the ventilation process, the partition can better block noise while guiding the airflow. Furthermore, the cover plate is connected to the main body to form an installation cavity, and the second shell is connected to the cover plate or the main body to form a structure in which the silencer cavity and the installation cavity are separated, which is farther away from the noise source, the noise transmission path is longer, and the noise intensity is more attenuated.

[0012] In any of the above technical solutions, the cover and the body are an integrated structure or a split structure.

[0013] In this technical solution, on the one hand, the cover and body are an integrated structure, which facilitates installation, increases the airtightness of the structure, improves the efficiency of air intake, prevents noise from radiating outward from the installation joint, reduces the path of noise radiation outward, and reduces noise transmission. On the other hand, the cover and body are separated structures, which facilitates disassembly and installation. At the same time, the specific structure of the cover and body can be set according to the specific model, improving design flexibility and cost-effectiveness. The structure of the body and cover can be improved separately according to the noise reduction effect to achieve the greatest possible noise reduction.

[0014] In any of the above technical solutions, the hot water treatment equipment further includes: a first mounting hole, which is opened on the first shell; a second mounting hole, which is opened on the second shell, and the center of the first mounting hole and the center of the second mounting hole are collinear.

[0015] In this technical solution, the hot water treatment equipment also includes a first mounting hole and a second mounting hole, wherein the first mounting hole is opened on the first shell and the second mounting hole is opened on the second shell. The center of the first mounting hole and the center of the second mounting hole are collinear for easy installation.

[0016] In any of the above technical solutions, the hot water treatment equipment further includes: a combustion component, which is arranged in the installation cavity, and the combustion component is located on a side of the installation cavity away from the muffler cavity.

[0017] In this technical solution, the hot water treatment equipment also includes a combustion element, and the position of the combustion element is limited, and it is arranged in the installation cavity, so that the combustion element that mainly generates noise during water treatment is separated from the silencer cavity. While the air is being taken in and ventilated, the path of the noise radiating to the outside is greatly extended. Furthermore, the combustion element is located on the side of the installation cavity away from the silencer cavity, so that the air is taken in and ventilated further away from the noise source, thereby reducing the propagation of noise from the source.

[0018] In any of the above technical solutions, the hot water treatment equipment also includes: a pipe fitting, one end of which is connected to the combustion component, and the other end of the pipe fitting is passed through the first mounting hole and the second mounting hole; a sealing member, which is sleeved on the pipe fitting and is located between the pipe fitting and the first mounting hole and the second mounting hole.

[0019] In this technical solution, the hot water treatment equipment also includes a pipe fitting and a sealing member. Specifically, one end of the pipe fitting is connected to the combustion member, and the other end of the pipe fitting is passed through the first mounting hole and the second mounting hole, so that the exhaust gas generated by the combustion member during the combustion process is discharged. The sealing member is sleeved on the pipe fitting and is located between the pipe fitting and the first mounting hole and the second mounting hole. When the smoke pipe extends out of the hot water treatment equipment, there are some gaps between the smoke pipe and the hot water treatment equipment. These gaps are also one of the paths for noise radiation. These gaps are sealed by the sealing member to reduce noise radiation.

[0020] In any of the above technical solutions, the main body includes: a back plate, which is provided with a receiving groove for placing the silencer; and a panel, which is arranged opposite to the back plate and is provided with the silencer.

[0021] In this technical solution, the main body includes a back panel and a panel. Specifically, a receiving groove is provided on the back panel. By eliminating the air inlet on the back, the back panel increases the space for placing sound-absorbing materials, thereby enhancing the noise reduction effect. Furthermore, the panel and the back panel are arranged back to back, and sound-absorbing materials are also provided on the panel to achieve multi-directional noise reduction.

[0022] In any of the above technical solutions, the vent is arranged on a side of the second shell close to the panel.

[0023] This technical solution defines the specific location of the vents, specifically, on the side of the second housing near the panel. This increases the path length between the air inlet and the vents, thereby lengthening the noise propagation path and enhancing noise attenuation. It also maximizes the distance between the air inlet and the noise source, effectively reducing noise and providing a better user experience.

[0024] In any of the above technical solutions, the ratio of the area of ​​the vent directly connected to the air inlet to the area of ​​the air inlet is less than or equal to 0.3.

[0025] In this technical solution, noise radiates outward through the silencer cavity. The silencer cavity can be regarded as a secondary radiation source, and the air inlet of the silencer cavity can be regarded as a radiation outlet. The vent is connected to the air inlet through a partition, so that when the noise radiates outward, the direct connection between the secondary radiation source and the noise radiation outlet, that is, the vent and the air inlet is cut off. The noise radiates to the surroundings through the vent, forming a shadow area behind the air guide plate. The sound wave needs to be reflected at least once to reach the shadow area. The ratio of the area between the vent and the air inlet through the partition to the area of ​​the air inlet is less than or equal to 0.3, that is, the area of ​​the overlapping part of the two air outlets is less than or equal to 0.3, so that the air inlet is located in the shadow area as much as possible, reducing the exposed area directly corresponding to the vent, so that the noise direct transmission area is less than or equal to 30% of the air inlet area, thereby reducing the proportion of noise directly transmitted through the air inlet.

[0026] In any of the above technical solutions, the partition includes: a shielding portion, which is arranged opposite to the air inlet; and a guide portion, which is arranged at at least one end of the shielding portion and extends toward one side of the vent.

[0027] In this technical solution, the baffle includes a shielding portion and a flow-guiding portion. Specifically, the shielding portion is disposed opposite the air inlet, and the flow-guiding portion is disposed at at least one end of the shielding portion, extending toward one side of the vent. The shielding portion and the flow-guiding portion cooperate to guide airflow while effectively blocking noise transmission. The flow-guiding portion is disposed at at least one end of the shielding portion. In actual processing, it can be disposed on one or both sides of the shielding portion. Any connection method that can achieve the purpose of guiding airflow and effectively blocking noise transmission is within the scope of protection of this application.

[0028] In any of the above technical solutions, the shielding portion is connected to the air guide portion; or the shielding portion and the air guide portion are spaced apart from each other along the direction from the air inlet to the vent.

[0029] In this technical solution, the installation position of the shielding part is limited. On the one hand, the shielding part is connected to the guide part. On the other hand, the shielding part and the guide part are spaced apart along the direction from the air inlet to the vent, so that the shielding part and the guide part are used in combination, and a flow channel is formed between the shielding part and the guide part, so that the airflow advances in an S-shaped route in the silencing cavity, increasing the area of ​​contact with the airflow, reducing the overlapping area of ​​the air inlet and the vent, and increasing the distance of noise propagation. The noise propagates in the cavity for a longer time, and the noise reaches the air inlet located in the shadow area after multiple reflections, and the intensity of the noise is more attenuated, thereby achieving a better noise reduction effect.

[0030] In any of the above technical solutions, the guide portion includes: an arc-shaped plate, a long strip plate or a bent plate.

[0031] In this technical solution, on the one hand, the guide plate includes an arc-shaped plate, which is a curved plate with a certain radius and arc length. It has a higher strength to withstand deformation and a stronger sense of design. It increases the area in contact with the airflow, changes the angle of contact with the airflow, better guides the airflow flow, and makes the noise propagation path longer, so that the noise propagates in the silencer chamber for a longer time and the intensity attenuates more. On the other hand, the guide plate includes a long strip plate with a simple structure, which is easy to install in the silencer chamber to guide the flow of airflow and block the propagation of noise. On the other hand, the guide part includes a bent plate, so that the guide plate forms a tortuous flow channel in the silencer chamber, thereby increasing the propagation path of the noise in the process of radiating to the outside world, using reflection to reduce the propagation intensity of the noise, further reducing the area of ​​direct connection between the air inlet and the vent, and reducing direct transmission of noise.

[0032] In any of the above technical solutions, there are multiple partitions, and the multiple partitions are arranged obliquely relative to the direction from the air inlet to the vent; and the multiple partitions are arranged at intervals along the direction perpendicular to the air inlet to the vent.

[0033] In this technical solution, multiple partitions are arranged at intervals and multiple partitions are arranged at an angle, that is, multiple flow channels are formed between the multiple partitions. Furthermore, by arranging them at an angle relative to the direction from the air inlet to the vent, the extension direction of the flow channel is also inclined relative to the direction from the air inlet to the vent, thereby setting multiple barriers between the vent and the air inlet, thereby better blocking noise while guiding the airflow in.

[0034] In any of the above technical solutions, the partition is located between the air inlet and the first mounting hole; or there are multiple partitions, and the multiple partitions are distributed on both sides of the first mounting hole.

[0035] In this technical solution, on the one hand, there is only one baffle, located between the air inlet and the first mounting hole, creating a barrier between the vent and the air inlet, blocking the connection between the vent and the air inlet. On the other hand, multiple baffles are symmetrically distributed about the line connecting the center of the first mounting hole and the center of the second mounting hole, thereby creating multiple barriers between the vent and the air inlet, evenly distributing the air flow from the air inlet and effectively blocking noise.

DETAILED DESCRIPTION

[0058] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that the embodiments of the present invention and the features therein can be combined with each other without conflict.

[0059] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0060] Refer to the following Figures 1 to 18 A hot water treatment apparatus 1 according to some embodiments of the present invention is described.

[0061] like Figures 1 to 18 As shown, one embodiment of the present invention provides a hot water treatment device 1 , which includes a first shell 10 and a second shell 20 .

[0062] Among them, such as Figures 1 to 5 As shown, the first housing 10 includes a mounting cavity 12 and an air inlet 162. The second housing 20 is connected to the first housing 10 and is located within the mounting cavity 12. The second housing 20 includes a vent 22. The second housing 20 and the first housing 10 form a muffler cavity 40. The air inlet 162 communicates with the muffler cavity 40, and the vent 22 communicates with the muffler cavity 40 and the mounting cavity 12.

[0063] The hot water treatment device 1 provided in this embodiment includes a first housing 10 and a second housing 20 connected to the first housing 10. The first housing 10 includes a mounting cavity 12 and an air inlet 162, and the second housing 20 includes a vent 22. The second housing 20 and the first housing 10 enclose a muffler cavity 40. The air inlet 162 is connected to the muffler cavity 40, and the vent 22 is connected to the muffler cavity 40 and the mounting cavity 12. Furthermore, the air inlet 162 is connected to the vent 22 and the muffler cavity 40.

[0064] The hot water treatment device 1 provided in the present application is formed by a first shell 10 with an air inlet 162 and a second shell 20 with a vent 22 to form a silencer chamber 40. The installation chamber 12 is separated from the silencer chamber 40, so that the entire shell assembly is formed with two air inlets 162. That is, during the air intake process, the airflow enters the silencer chamber 40 from the air inlet 162, and then enters the installation chamber 12 through the vent 22. During the operation of the hot water treatment device 1, the noise enters the silencer chamber 40 through the vent 22, and then can be radiated to the outside through the air inlet 162. Through the arrangement of the vent 22, the silencer chamber 40 and the air inlet 162, the radiation path of the generated noise is greatly extended during the radiation process to the outside, and the noise radiated to the outside is greatly attenuated, so as to achieve the purpose of reducing noise and improving user comfort.

[0065] Furthermore, the vent 22 is arranged on the side of the second shell 20 away from the air inlet 162, which greatly extends the radiation path of the noise when it is radiated to the outside world during air intake and ventilation, and has the unique performance advantage of noise reduction. The vent 22 is located on the side of the second shell 20 away from the air inlet 162, which makes the air intake and ventilation further away from the noise source, thereby reducing the propagation of noise from the source.

[0066] Furthermore, the air inlet 162 may be disposed on any wall surface of the first housing 10 except the wall surface used for installation, so as to achieve a better noise reduction effect.

[0067] Furthermore, if Figure 5 、 Figure 9 、 Figures 10 to 17 As shown, the hot water treatment equipment 1 further includes: a partition 30 , which is provided on the first shell 10 and located in the muffler cavity 40 , and the partition 30 is arranged opposite to the air inlet 162 .

[0068] In this embodiment, the hot water treatment device 1 further includes a partition 30, which is provided on the first shell 10, is located in the silencer chamber 40, and is arranged opposite to the air inlet 162. On the one hand, the partition 30 is used to guide the flow of air, so that after the air flows in through the air inlet 162, it is blocked by the partition 30, and the air flows along the partition 30 into the vent 22, playing a guiding role. On the one hand, the partition 30 cuts off the direct connection between the air inlet 162 and the vent 22, so that the noise enters the silencer chamber 40 from the vent 22 and radiates to the partition 30, and then the partition 30 blocks part of the noise from being transmitted out through the air inlet 162, so that the generated noise has a significantly extended radiation path during the radiation process to the outside world, and on the other hand, after being blocked, the noise radiated to the outside world is significantly attenuated, so as to achieve the purpose of reducing noise and improving user comfort.

[0069] Furthermore, the partition 30 is positioned opposite the air inlet 162, located between the air inlet 162 and the vent 22. This allows air to flow through the air inlet 162 on the first housing 10 and be blocked by the partition 30. The air then flows along the partition 30 and into the vent 22 on the connecting plate, thereby acting as a guide. Furthermore, noise enters the silencing chamber 40 through the vent 22 and radiates to the partition 30. This in turn prevents some of the noise from radiating out through the air inlet 162, significantly extending the radiation path of the generated noise as it radiates to the outside world. The noise radiated to the outside world is significantly attenuated, thereby achieving the purpose of noise reduction.

[0070] Furthermore, if Figures 1 to 3As shown, the first housing 10 includes a cover 16 and a body 14. An air inlet 162 is provided on the cover 16, a partition 30 is connected to the cover 16, and the cover 16 and the body 14 are connected to form a mounting cavity 12. The second housing 20 is connected to the cover 16 or the body 14.

[0071] Specifically, the first housing 10 includes a cover plate and a body 14. The cover plate 16 and the body 14 enclose an installation cavity 12, which is used to install working parts and electrical components. The air inlet 162 is provided on the cover plate, and the partition 30 is connected to the cover plate, so that the air inlet 162 and the working parts are blocked by the second housing 20 and the partition 30. Therefore, during the ventilation process, while guiding the airflow, it can better block noise. Furthermore, the second housing 20 is connected to the cover plate or the body 14, forming a structure that separates the silencer cavity 40 from the installation cavity 12. This structure is further away from the noise source, the noise transmission path is longer, and the noise intensity is more attenuated.

[0072] In one embodiment of the present invention, further, the cover plate and the main body 14 are an integrated structure, thereby achieving convenient installation, increasing the air tightness of the structure, improving the efficiency of air intake, avoiding noise radiation outward from the installation joints, reducing the path of noise radiation outward, and reducing noise propagation.

[0073] In one embodiment of the present invention, further, the cover and the main body 14 are split structures, which are convenient for disassembly and installation. At the same time, the specific structures of the cover 16 and the main body 14 can be set according to the specific model to improve design flexibility and economy. The structures of the main body 14 and the cover 16 can be improved separately according to the noise reduction effect to achieve maximum noise reduction.

[0074] Furthermore, if Figure 6 and Figure 7 As shown, the hot water treatment device 1 further includes: a first mounting hole 50 and a second mounting hole 60. The center of the first mounting hole 50 and the center of the second mounting hole 60 are collinear.

[0075] Furthermore, the hot water treatment equipment 1 further includes: pipes and sealing elements.

[0076] Specifically, the first mounting hole 50 is opened on the first shell 10, and the second mounting hole 60 is opened on the second shell 20. The center of the first mounting hole 50 and the center of the second mounting hole 60 are collinear. One end of the pipe fitting is connected to the combustion part, and the other end of the pipe fitting is passed through the first mounting hole 50 and the second mounting hole 60; the sealing part is sleeved on the pipe fitting, and the sealing part is located between the pipe fitting and the first mounting hole 50 and the second mounting hole 60.

[0077] Specifically, the pipe is used to discharge exhaust gas generated by the combustion element during the combustion process. Furthermore, when the smoke pipe extends out of the hot water treatment equipment 1, there are some gaps between the smoke pipe and the hot water treatment equipment 1. These gaps are also one of the paths for noise radiation. The sealant is used to block these gaps to reduce noise radiation.

[0078] In one embodiment of the present invention, further, Figure 9 and Figure 10 As shown, a mounting seat 70 is also included. The mounting seat 70 is set on the cover body 16. The mounting seat 70 is located in the muffler cavity 40. The first mounting hole 50 is set through the mounting seat 70.

[0079] In one embodiment of the present invention, further, Figure 9 and Figure 10 As shown, a mounting base 70 is further included. The mounting base 70 is arranged on the second shell 20 . The mounting base 70 is located in the muffler cavity 40 , and the second mounting hole 60 is set through the mounting base 70 .

[0080] In this embodiment, by providing a mounting seat 70 in the silencing chamber 40 , the airtightness of the silencing chamber 40 is enhanced, thereby preventing the propagation of noise.

[0081] In any of the above embodiments, further, the hot water treatment equipment 1 further includes a combustion element.

[0082] In this embodiment, the combustion component is arranged in the installation cavity 12, so that the combustion component that mainly generates noise during the operation of the hot water treatment equipment 1 is separated from the silencer cavity 40, and the noise radiation path to the outside world is greatly extended while the air is taken in and ventilated.

[0083] Furthermore, the combustion component is located on a side of the installation cavity 12 away from the muffler cavity 40, so that the air intake and ventilation are further away from the noise source, thereby reducing the spread of noise from the source.

[0084] In any of the above embodiments, further, Figure 3 、 Figure 4 and Figure 5 As shown, the body 14 includes a back plate 142 and a front plate 144 , and the front plate 144 is arranged opposite to the back plate 142 .

[0085] In this embodiment, the main body 14 includes a back panel 142 and a panel 144. Specifically, a receiving groove 1422 is provided on the back panel 142, and the receiving groove 1422 is used to place the sound-absorbing component; by eliminating the back air inlet 162, the back panel 142 increases the space for placing the sound-absorbing material, thereby enhancing the noise reduction effect.

[0086] Furthermore, the back panel 142 is used for the side of the equipment facing the installation surface, the panel 144 and the back panel 142 are arranged back to back, and the air inlet 162 is removed from the back panel 142, so that the air inlet 162 is away from the installation surface, so that during the operation of the hot water treatment equipment 1, the radiation noise is prevented from being reflected and coupled with the installation surface to cause noise enhancement.

[0087] Furthermore, sound-absorbing materials are also provided on the panel 144 to achieve multi-directional noise reduction.

[0088] Specifically, the sound-absorbing material includes sound-absorbing cotton.

[0089] Furthermore, the vent 22 is located on the side of the second housing 20 near the panel 144. This increases the path length between the air inlet 162 and the vent 22, thereby extending the noise propagation path and enhancing noise attenuation. This also maximizes the distance between the air inlet 162 and the noise source, effectively reducing noise and providing a better user experience.

[0090] In any of the above embodiments, if Figure 18 As shown, the ratio of the area of ​​the vent 22 directly communicating with the air inlet 162 to the area of ​​the air inlet 162 is less than or equal to 0.3.

[0091] In this embodiment, the noise is radiated outward through the air inlet 162 of the first shell 10. The cover 16 of the first shell 10 can be regarded as a secondary radiation source, and the air inlet 162 of the first shell 10 can be regarded as a radiation outlet. The noise entering the silencer cavity 40 through the vent 22 is radiated to the partition 30. When the noise radiates outward, the direct connection between the secondary radiation source and the noise radiation outlet, that is, the vent 22 and the air inlet 162 is cut off. After passing through the vent 22, the noise radiates to the surroundings, forming a shadow area behind the partition 30. The noise sound waves need to be reflected at least once before they can reach the shadow area. The ratio of the area directly connected between the vent 22 and the air inlet 162 to the area of ​​the air inlet 162 is less than or equal to 0.3, that is, the area of ​​the overlapping part of the two air vents is less than or equal to 0.3, so that the air inlet 162 is located in the shadow area as much as possible, reducing the exposed area directly corresponding to the vent 22, so that the direct transmission area of ​​the noise is less than or equal to 30% of the area of ​​the air inlet 162, thereby reducing the proportion of noise directly transmitted through the air inlet 162.

[0092] Specifically, if Figure 18 As shown, the noise is radiated into the muffler cavity 40 through the vent 22. Part of the area of ​​the air inlet 162 is blocked by the partition 30, and the other part of the area is directly connected to the vent 22, forming a Figure 18The straight-through area S1 shown is achieved by setting the position of the partition 30 and the area on the opposite side of the partition 30 and the vent 22 to achieve a ratio of the straight-through area S1 to the total area of ​​the air inlet 162 less than or equal to 0.3, so that the air inlet 162 is located in the shaded area in the figure as much as possible, reducing the exposed area directly corresponding to the vent 22, and thereby reducing the proportion of noise directly transmitted through the air inlet 162.

[0093] Furthermore, the area of ​​the air inlet 162 is in the range of 2000 mm. 2 Up to 5000mm 2 The area of ​​the vent 22 is in the range of 3000mm 2 Up to 8000mm 2 .

[0094] By limiting the area of ​​the air inlet 162 to 2000mm 2 Up to 5000mm 2 The area of ​​the vent 22 is in the range of 3000mm 2 Up to 8000mm 2 The overlapping area of ​​the air inlet 162 and the ventilation opening 22 does not exceed 30% of the total area of ​​the air inlet 162. The specific value can be determined based on the different volumes of the equipment. Different volumes correspond to different gas volumes, and different gas volumes correspond to different amounts of air required for combustion. Therefore, the area of ​​the air inlet 162 can be set to meet the requirements. This ensures that the air intake requirements are met while minimizing the outward radiation of noise.

[0095] In one embodiment of the present invention, further, Figure 11 、 Figure 13 、 Figure 14 and Figure 15 As shown, the partition 30 includes a shielding portion 32 and a flow guiding portion 34 .

[0096] The shielding portion 32 is disposed on the first shell 10 , and is opposite to the air inlet 162 ; the air guide portion 34 is disposed on the first shell 10 , and is located on at least one side of the shielding portion 32 .

[0097] Specifically, the shielding portion 32 is positioned opposite the air inlet 162, thereby forming a tortuous flow path between the shielding portion 32 and the first housing 10. This shielding portion 32 and the first housing 10 block and reflect noise entering through the vent 22, extending the noise propagation path, effectively attenuating and blocking the noise, and thus achieving the purpose of noise reduction. Furthermore, by locating the shielding portion 32 on the side wall opposite the vent 22, the layout space of the shielding portion 32 is increased, allowing for a variety of layout arrangements to achieve optimal noise reduction effects.

[0098] Furthermore, the guide portion 34 is provided on at least one side of the shielding portion 32. The guide portion 34 cooperates with the shielding portion 32 to achieve the function of guiding the inflow of air while better blocking the propagation of noise.

[0099] Specifically, there is one guide portion 34 connected to one end of the shielding portion 32. Alternatively, there are two guide portions 34 connected to both ends of the shielding portion 32. Providing guide portions 34 at one or both ends of the shielding portion 32 extends the flow path of the partition 30, increases the noise blocking area, and enhances the noise reduction effect.

[0100] Specifically, the shielding portion 32 and the guide portion 34 can be an integrated structure or a split structure. The specific structure and setting method can be specifically set according to the space of the silencer cavity 40 to achieve the best noise reduction effect.

[0101] In one embodiment of the present invention, the partition 30 further includes: a shielding portion 32 and a guide portion 34, and the shielding portion 32 is connected to the guide portion 34; or the shielding portion 32 and the guide portion 34 are spaced apart along the direction from the air inlet 162 to the vent 22.

[0102] Specifically, if Figure 11 As shown, the shielding portion 32 is a straight plate, and the air guide portion 34 is also a straight plate. The shielding portion 32 and the air guide portion 34 are spaced apart in a direction perpendicular to the extension of the shielding portion 32. By configuring both the shielding portion 32 and the air guide portion 34 as straight plates, the structure is simplified and easily installed in the muffler chamber 40.

[0103] Furthermore, along the extending direction perpendicular to the shielding portion 32, the shielding portion 32 and the guide portion 34 are spaced apart, and the guide portion 34 is arranged close to the side of the vent 22, that is, along the direction from the air inlet 162 to the vent 22, there is a certain distance between the shielding portion 32 and the guide portion 34, and a flow channel for air flow is formed by setting a certain distance, and then during the air intake process, the air enters the silencer chamber 40 through the air inlet 162, and after being blocked by the shielding portion 32, it flows along the length direction of the shielding portion 32 to both sides of the shielding portion 32, and after flowing out of the shielding portion 32 During the flow toward the vent 22, it is blocked by the guide portion 34 and then flows toward the gap between the shielding portion 32 and the guide portion 34, and then flows toward the vent 22. Then, under the combined action of the shielding portion 32 and the guide portion 34, the airflow advances in an S-shaped route in the silencer cavity 40, reducing the overlapping area between the air inlet 162 and the vent 22, increasing the path for noise propagation, and the noise propagates longer in the cavity. The noise reaches the air inlet 162 located in the shadow area after multiple reflections, and the intensity of the noise is more attenuated, thereby achieving a better noise reduction effect.

[0104] In one embodiment of the present invention, further, Figure 14 As shown, the air guide portion 34 comprises an arc-shaped plate.

[0105] Specifically, the curved plates are positioned on one or both sides of the shielding portion 32. By utilizing the curved plate, the curved plate's curvature provides enhanced flow guidance, while also offering increased strength to withstand deformation. The combined use of the curved plate and shielding portion 32 increases the area of ​​contact with the airflow, effectively guiding the airflow. Furthermore, the noise propagation path is lengthened, increasing the noise propagation path within the silencing chamber 40 and significantly attenuating the noise intensity.

[0106] In one embodiment of the present invention, the partition 30 further includes: a shielding portion 32 and a flow guiding portion 34. The shielding portion 32 and the flow guiding portion 34 are both configured as straight plates.

[0107] Specifically, if Figure 13 As shown, the baffle 30 includes a shielding portion 32 and a guide portion 34 connected to each other. An angle is formed between the shielding portion 32 and the guide portion 34, and the guide portion 34 extends toward the vent 22. By forming an angle between the shielding portion 32 and the guide portion 34, that is, forming a bent structure with the opening of the angle facing the vent 22, the baffle 30 can guide the intake airflow on the one hand, and on the other hand, the increased length and area of ​​the baffle 30 can maximize noise blocking, further increase the noise radiation path, and achieve a better noise reduction effect.

[0108] Furthermore, there are two air guides 34, each connected to the opposite ends of the shielding portion 32. This creates a trumpet-like structure between the shielding portion 32 and the air guides 34. This trumpet-like structure guides the incoming airflow. Furthermore, the trumpet-like structure's mouth faces the vent 22, increasing the noise blocking area. This maximizes the noise blocking effect of the partition 30, while also increasing the noise radiation path and enhancing noise attenuation, resulting in a more effective noise reduction effect.

[0109] In one embodiment of the present invention, further, Figure 15 As shown, the partition 30 includes a shielding portion 32 and a guide portion 34. The guide portion 34 includes a bent plate, one end of the bent plate is connected to one end of the shielding portion 32, and the other end of the bent plate extends toward the other end of the shielding portion 32.

[0110] In this embodiment, the structure of the shielding portion 32 can be a straight plate, an arc-shaped plate, or a bent plate. The guide portion 34 is configured as a bent plate. By configuring the guide portion 34 as a bent plate as a whole and connecting the guide portion 34 to the end of the shielding portion 32, during the inhalation process, the airflow enters the air inlet 162 and flows along the shielding portion 32 to the guide portion 34, and then continues to flow along the structure of the guide portion 34 to the vent 22. That is, by configuring the guide portion 34 as a bent plate, the flow path of the airflow is extended, and the propagation path of the noise radiating outward is also extended, thereby increasing the degree of noise attenuation during the propagation process. Furthermore, the bent plate is provided on one or both sides of the shielding portion 32, which increases the area blocked by the partition 30 for noise radiating through the vent 22, that is, reduces the area directly connected to the vent 22 and the air inlet 162, further enhancing the noise reduction effect.

[0111] Specifically, the bent plate has a V-, U-, or W-shape. By providing the bent plate at at least one end of the shielding portion 32, a zigzag flow path is formed between the partition 30 and the first housing 10. This increases the propagation path of combustion noise during radiation to the outside world, reduces noise transmission intensity through reflection, and further reduces the area of ​​direct communication between the air inlet 162 and the vent 22, thereby reducing direct noise transmission. The specific structural configuration is determined based on the specific product characteristics and is not limited here.

[0112] In one embodiment of the present invention, further, Figure 12 、 Figure 16 and Figure 17 As shown, there are multiple partitions 30, and the multiple partitions 30 are arranged obliquely relative to the direction from the air inlet 162 to the vent 22; and the multiple partitions 30 are arranged at intervals along the direction perpendicular to the air inlet 162 to the vent 22.

[0113] Specifically, the plurality of partitions 30 are spaced apart in a direction parallel to the surface of the side wall where the air inlet 162 is located, and the partitions 30 are inclined relative to the side wall where the air inlet 162 is located.

[0114] Specifically, by arranging multiple partitions 30 in a direction parallel to the surface of the side wall where the air inlet 162 is located, and the multiple partitions 30 are arranged at an angle relative to the side wall where the air inlet 162 is located, multiple flow channels are formed between the multiple partitions 30. Furthermore, by arranging them at an angle on the first shell 10, the extension direction of the flow channel is also inclined relative to the direction from the air inlet 162 to the vent 22, thereby providing multiple barriers between the vent 22 and the air inlet 162, thereby better blocking noise while guiding the airflow in.

[0115] Furthermore, the plurality of partitions 30 may be straight plates, curved plates or bent plates. On one hand, the partitions 30 include straight plates, which have a simple structure and are easy to install on the first housing 10 to block the propagation of noise. On the other hand, Figure 9 、 Figure 10 and Figure 16 As shown, the partition 30 includes a curved plate, which makes it more resistant to deformation, increases the distance that the noise propagates in the muffler chamber 40 after it is transmitted from the vent 22, and reduces the transmission intensity of the noise. Figure 17 As shown, the partition 30 includes a bent plate, and the angle of the bent plate can be specifically set according to the air demand, so as to extend the propagation path of the noise and reduce the propagation intensity of the noise by reflection.

[0116] In one embodiment of the present invention, further, Figure 12 As shown, there is only one partition 30 located between the mounting base and the air inlet 162 , so that a barrier is provided between the vent 22 and the air inlet 162 , thereby blocking the connection between the vent 22 and the air inlet 162 .

[0117] Specifically, the length of the partition 30 is greater than the width of the mounting seat, thereby achieving the functions of guiding the intake air through the partition 30 and blocking the propagation of noise.

[0118] Specifically, the partition 30 is arranged on both sides of the mounting seat, and one end of the partition 30 is connected to the mounting seat, so that the partition 30 and the mounting seat together form a shielding wall to guide the air flow entering the air inlet 162 and block the noise radiated by the vent 22.

[0119] In one embodiment of the present invention, further, Figure 16 and Figure 17 As shown, multiple baffles 30 are distributed on both sides of the mounting base. The baffles 30 on both sides of the mounting base 70 are symmetrically distributed about the line connecting the centers of the first mounting hole 50 and the second mounting hole 60, thereby balancing the gas flow on both sides of the mounting base and effectively blocking noise. The mounting base is a cylindrical structure, and the central hole of the cylindrical structure serves as the first mounting hole 50 or the second mounting hole 60 for the smoke pipe, for mounting the smoke pipe.

[0120] Furthermore, the hot water treatment device 1 includes a water heater. Specific embodiments

[0122] This embodiment provides a gas water heater. Figures 1 to 18As shown, the gas water heater includes a first shell 10, a second shell 20, a partition 30 and a burner. The first shell 10 includes a cover 16 and a body 14. The air inlet 162 is provided on the cover 16, and the vent 22 is provided on the second shell 20. The partition 30 is connected to the cover 16, and the cover 16 is connected to the body 14 to form an installation cavity 12. The second shell 20 and the first shell 10 form a silencer cavity 40, the air inlet 162 is connected to the silencer cavity 40, and the vent 22 is connected to the silencer cavity 40 and the installation cavity 12. The combustion component is provided in the installation cavity 12, and the combustion component is located on the side of the installation cavity 12 away from the silencer cavity 40, so that the air intake and ventilation are further away from the noise source, thereby reducing the propagation of noise from the source.

[0123] Specifically, during operation, air flows from the air inlet 162 of the cover 16 into the silencer chamber 40, and then enters the interior of the installation chamber 12 from the vent 22 of the second shell 20 along the partition 30. Compared with the traditional water heater's direct air intake from the back, the top air intake is farther away from the noise source, the noise transmission path is longer, and the noise intensity is more attenuated. This solution utilizes the cover 16 and the second shell 20 of the water heater to form two air inlets 162, which can isolate noise while taking in air for ventilation, and has the unique performance advantage of noise reduction. In addition, this solution sets a partition 30 inside the cover 16, which can better block noise while guiding the airflow in.

[0124] like Figures 10 to 17 The illustrated diagram shows various air distribution schemes for the partition 30. Different air distribution schemes have different flow resistance and sound insulation performance, and need to be adjusted and selected according to the performance requirements of the entire machine.

[0125] Furthermore, the area of ​​the air inlet 162 is 2000mm 2 Up to 5000mm 2 The area of ​​the ventilation opening 22 is 3000mm 2 Up to 8000mm 2 When noise radiates outward through the air inlet, the second shell 20 can be regarded as a secondary radiation source, and the air inlet 162 of the cover 16 can be regarded as a radiation outlet. The partition 30 is used to cut off the direct communication between the secondary radiation source and the noise radiation outlet, that is, the direct communication between the vent 22 of the second shell 20 and the air inlet 162 of the cover 16.

[0126] Figure 18 This is a schematic diagram of the partition 30 blocking direct noise transmission. Noise radiates through the vents 22 of the second housing 20, forming a shadow area behind the partition 30. Sound waves must reflect at least once before reaching the shadow area. Therefore, the partition 30 is required to position the air inlet 162 of the cover 16 as much as possible within the shadow area, reducing direct noise transmission. Furthermore, the ratio of the area of ​​the direct noise transmission region (S1) to the total area (S2) of the air inlet 162 is less than or equal to 0.3.

[0127] Furthermore, the air inlet 162 of the cover 16 can be located on the back side, front side, or both sides of the cover 16. The location of the vent 22 of the second housing 20 is not limited to being located on the front side near the panel 144.

[0128] Existing gas water heaters mainly adopt the back air intake solution, and multiple air inlets 162 are opened on the back plate 142 of the water heater. Figures 4 to 7 As shown, the air inlet 162 of the back plate 142 is cancelled, the back plate 142 is formed in one piece, and the air inlet 162 is moved up to the cover 16, making the back appearance of the hot water tank more simple and beautiful.

[0129] In addition, a smoke pipe opening is left at the top of the gas water heater. To facilitate the installation of the smoke pipe, the aperture of the smoke pipe opening is generally larger than the aperture of the smoke pipe. There are some gaps between the smoke pipe opening at the top of the main body 14 and the smoke pipe. These gaps are also one of the paths for noise radiation. This solution uses silicone sealants to seal this part of the gap to reduce noise radiation. The seal can be installed between the through hole of the cover 16 and the smoke pipe. Alternatively, the seal is installed between the through hole of the second shell 20 and the smoke pipe. Alternatively, the seal is installed between the second shell 20 and the volute of the centrifugal fan. In addition, the noise reduction effect can be further enhanced by adding porous sound-absorbing materials inside the water heater. For example, areas for accommodating porous sound-absorbing materials can be arranged in the accommodating grooves of the panel 144 and the back plate 142.

[0130] The gas water heater provided in this embodiment has a ventilation structure consisting of a cover 16, a second housing 20, and a partition 30 positioned at the top of the water heater. The air inlet channel is optimized, positioning the air inlet 162 away from the main noise source of the water heater. This also blocks the direct noise radiation path, achieving vibration and noise reduction. The gas water heater provided by the present invention not only has a simple appearance but also achieves excellent noise reduction, providing users with a better user experience.
