Description

Technical Field

[0001] This invention relates to the technical field of water heaters, and more particularly to shock-absorbing housings and gas water heaters. Background Technology

[0002] In daily life, gas water heaters are key devices for providing a stable supply of hot water, and their performance and safety are directly related to users' quality of life and safety.

[0003] Chinese invention patent with publication number CN114963496A discloses a gas water heater and its control method. The gas water heater adopts a relatively closed combustion heat exchange module and a fresh air module. The flue gas generated after the gas and air are mixed and burned in the combustion chamber is discharged through a special exhaust pipe in the fresh air module.

[0004] Because the entire combustion and exhaust system is located within a relatively independent and enclosed space, the operation of the internal fan, water flow, and energy release from combustion all cause vibrations of varying degrees when the water heater is running. These vibrations cannot be effectively mitigated within the enclosed space and are easily transmitted to the water heater's outer casing, causing significant vibration. This casing vibration not only generates noise, interfering with normal use, but can also cause loosening and wear of internal components due to prolonged vibration, affecting the water heater's normal operation and lifespan, and potentially even posing safety hazards. Summary of the Invention

[0005] The purpose of this invention is to provide a shock-absorbing housing and a gas water heater, which solves the problem that in the prior art, the vibrations generated by various internal components of a gas water heater during operation are concentrated in the internal space of the housing and are difficult to be effectively mitigated. This results in a large vibration intensity transmitted to the housing, which not only generates a lot of noise and interferes with the normal use of the user, but may also cause loosening and wear of internal parts, reduce the safety factor, or even cause safety hazards.

[0006] To achieve this objective, the present invention adopts the following technical solution: In a first aspect, the present invention provides a shock-absorbing housing, comprising: Face shell; A bottom shell is disposed on the top shell and surrounds the top shell to form an installation space for mounting devices; the inner side of the bottom shell is partially concave. A vibration damping component is disposed on the bottom shell and surrounds a partially concave area of ​​the bottom shell to form a vibration damping cavity to mitigate the vibration intensity transmitted to the bottom shell during operation.

[0007] Optionally, the portion of the bottom shell facing the shock-absorbing component is partially recessed to enclose the shock-absorbing component and form the shock-absorbing cavity.

[0008] Optionally, the shock absorption assembly includes: A shock-absorbing part is disposed on the bottom shell, and the shock-absorbing part and the opposite side of the bottom shell are spaced apart to form the shock-absorbing cavity.

[0009] Optionally, the damping portion is at least partially recessed on the side facing the bottom shell to form the damping cavity.

[0010] Optionally, the shock absorption assembly further includes: A sealing gasket is disposed between the shock-absorbing part and the bottom shell to mitigate the vibration intensity transmitted from the shock-absorbing part to the bottom shell.

[0011] Optionally, the shock-absorbing part includes: Fixing plate; A buffer plate is disposed on the fixed plate, and the buffer plate and the fixed plate enclose a plurality of spaced buffer cavities, and at least some of the buffer cavities contain buffer balls that can sway within the buffer cavities.

[0012] Optionally, the buffer plate and buffer ball are made of elastic material.

[0013] Optionally, the volume of the buffer ball is 30% to 70% of the volume of the buffer cavity.

[0014] Optionally, the shock-absorbing component is located in the middle of the bottom shell.

[0015] Optionally, the shock-absorbing assembly is detachably connected to the bottom shell; and / or, The bottom shell is provided with multiple sound-absorbing holes spaced apart at locations corresponding to the shock-absorbing cavity; and / or, The damping cavity is filled with a sound-absorbing layer.

[0016] In a second aspect, the present invention also provides a gas water heater, comprising: The shock-absorbing housing as described in any one of the first aspects; The burner is housed within the shock-absorbing housing; A heat exchanger is installed inside the shock-absorbing housing and uses the heat generated by the burner to heat the water flow.

[0017] The beneficial effects of this invention are: Firstly, by incorporating shock-absorbing components and a partially concave structure on the bottom shell to form a shock-absorbing cavity, the vibrations generated by the devices within the installation space are first transmitted to the shock-absorbing components and cavity for effective damping before being transmitted to the bottom shell. This significantly reduces the intensity of the vibration transmitted to the bottom shell, resulting in minimal vibration for both the bottom and top shells. Furthermore, the partially concave bottom shell further enhances its strength and shock resistance. Therefore, this shock-absorbing housing effectively mitigates vibrations generated by devices within the installation space during operation, ensuring that the vibration amplitude does not generate noise that interferes with normal user operation. It also effectively reduces the possibility of loosening or wear of components caused by vibration, thereby extending the overall lifespan of the machine and reducing the potential for safety hazards.

[0018] Secondly, during operation, the vibrations and noise generated by the burner and heat exchanger of this gas water heater can be effectively mitigated by the shock-absorbing components and the shock-absorbing cavity formed by the shock-absorbing components and the bottom shell. As a result, the vibrations and noise transmitted to the bottom shell are relatively small, the overall vibration amplitude of the shock-absorbing casing is small, and the noise is weak, ensuring the comfort of users during use. It can also effectively extend the service life of the gas water heater and reduce the possibility of causing safety hazards. Attached Figure Description

"Below," "below," and "under" the second feature includes the first feature being directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0024] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0025] like Figures 1 to 6 As shown, the present invention provides a shock-absorbing housing and a gas water heater.

[0026] The shock-absorbing housing includes a front shell (not shown in the figure), a bottom shell 1, and a shock-absorbing component 2. The bottom shell 1 is disposed on the front shell and encloses the front shell to form an installation space for mounting the device. The inner side of the bottom shell 1 is partially concave. The shock-absorbing component 2 is disposed on the bottom shell 1 and covers the partially concave area of ​​the bottom shell 1 to enclose and form a shock-absorbing cavity to mitigate the vibration intensity transmitted to the bottom shell 1 by the device during operation.

[0027] By incorporating a shock-absorbing component 2 and a partially concave structure on the bottom shell 1 to form a shock-absorbing cavity, when a device in the installation space operates, the resulting vibration is first transmitted to the shock-absorbing component 2 and the shock-absorbing cavity to effectively mitigate the vibration before it is transmitted to the bottom shell 1. This significantly reduces the intensity of the vibration transmitted to the bottom shell 1, thus preventing noticeable vibration in both the bottom shell 1 and the top shell as a whole. Furthermore, the partially concave design of the bottom shell 1 further enhances its strength and shock resistance. Therefore, this shock-absorbing housing effectively mitigates the vibration generated by devices in the installation space during operation, ensuring that the vibration amplitude does not generate noise that interferes with normal user operation. It also effectively reduces the possibility of loosening or wear of components caused by vibration, thereby extending the overall service life of the machine and reducing the potential for safety hazards.

[0028] Specifically, both the front shell and the bottom shell 1 are made of metal plates, which can be fixed together by snap-fitting, bonding, or welding to form an installation space. This installation space is used to install components, which may include burners, heat exchangers, water supply modules, and fans, etc. Components are generally mounted directly or indirectly on the bottom shell 1; therefore, vibrations generated by the components during operation are transmitted to the bottom shell 1 more significantly. A vibration damping assembly 2 is installed on the inner wall of the bottom shell 1. This assembly can at least partially separate the components from the bottom shell 1. Furthermore, recessed spaces can be provided between the vibration damping assembly 2 and the bottom shell 1, or on their opposite sides, forming a vibration damping cavity. This ensures that vibrations generated by the components during operation are preferentially transmitted to the vibration damping assembly 2 and the vibration damping cavity, thereby mitigating the vibration and effectively reducing the intensity of vibrations transmitted to the bottom shell 1.

[0029] In this embodiment, a recessed space is formed on the inner surface of the bottom shell 1, and the shock-absorbing component 2 is disposed over this space to form the aforementioned shock-absorbing cavity. To further improve the strength of the bottom shell 1, the local concavity of the bottom shell 1 can be formed by locally stretching the bottom shell 1 downwards, thus causing a local convexity on the outer surface of the bottom shell 1 and forming a locally concave space on the inner surface of the bottom shell 1. This creates a concave space without reducing the thickness of the bottom shell 1, which helps to enhance the strength of the area where the shock-absorbing component 2 is disposed on the bottom shell 1, thereby further improving the shock absorption effect of the bottom shell 1 itself.

[0030] Optionally, the shock-absorbing component 2 is located in the middle of the bottom shell 1.

[0031] Specifically, the middle of the bottom shell 1 is far from the edge, and the edge of the bottom shell 1 is connected to the front shell. Therefore, when vibration is transmitted to the bottom shell 1, the middle area of ​​the bottom shell 1 is more affected by the vibration. Therefore, the damping component 2 is set in the middle of the bottom shell 1, and the concave part of the bottom shell 1 is also located in the middle of the bottom shell 1, so as to specifically alleviate the vibration amplitude transmitted to the middle of the bottom shell 1.

[0032] Optionally, the shock-absorbing component 2 is detachably connected to the bottom shell 1.

[0033] Specifically, the shock absorber 2 can be detachably connected to the base shell 1 by means of snap-fit ​​or bolt connection, which facilitates the installation of the shock absorber 2 and the processing of the base shell 1. In this embodiment, multiple mounting holes are opened at intervals along the edge of the shock absorber 2, and a bolt can be inserted into each mounting hole. A fixing hole is opened on the base shell 1 corresponding to each mounting hole for the bolt to pass through, thereby fixing the shock absorber 2 inside the base shell 1.

[0034] Optionally, the damping assembly 2 includes a damping section 21. The damping section 21 is disposed on the bottom shell 1, and the damping section 21 and the opposite side of the bottom shell 1 are spaced apart to form a damping cavity.

[0035] Specifically, the damping part 21 is a metal plate that covers the concave portion of the bottom shell 1, creating a certain gap between the lower side of the damping part 21 and the inner side of the bottom shell 1, thereby enclosing and forming the damping cavity described above. The edge of the metal plate is fixedly connected to the bottom shell 1 through the aforementioned detachable connection method, thereby sealing the damping cavity and improving the vibration buffering effect on the central region of the bottom shell 1.

[0036] Optionally, to further improve the vibration mitigation effect, the damping part 21 is at least partially concave on the side facing the bottom shell 1 to form a damping cavity. That is, the damping part 21 protrudes upward in the same manner, so that the bottom wall of the damping part 21 is concave. This not only improves the strength of the damping part 21 itself, but also increases the distance between the bottom wall of the damping part 21 and the inner surface of the bottom shell 1, thereby increasing the damping cavity and further improving the damping effect of the damping assembly 2.

[0037] Optionally, the shock-absorbing assembly 2 also includes a sealing gasket 22. The sealing gasket 22 is disposed between the shock-absorbing part 21 and the bottom shell 1 to mitigate the vibration intensity transmitted from the shock-absorbing part 21 to the bottom shell 1.

[0038] Specifically, the sealing gasket 22 is annular and fits against the bottom wall of the shock-absorbing part 21 and abuts against the inner surface of the bottom shell 1, thereby separating the shock-absorbing part 21 from the bottom shell 1. At the same time, the sealing gasket 22 is made of a material with a certain elasticity, such as rubber, so that the vibration generated by the shock-absorbing part 21 can be relieved by the sealing gasket 22, thereby effectively reducing the vibration intensity transmitted from the shock-absorbing part 21 to the bottom shell 1, further reducing the possibility of vibration of the bottom shell 1, and also reducing the noise generated by vibration.

[0039] To further improve the damping effect of the damping section 21, the damping section 21 can be composed of multiple plate-shaped structures stacked together. Optionally, the damping section 21 includes a fixed plate 211 and a buffer plate 212; the buffer plate 212 is disposed on the fixed plate 211, and the buffer plate 212 and the fixed plate 211 enclose a plurality of spaced buffer cavities 213, and at least some of the buffer cavities 213 contain buffer balls (not shown in the figure) that can sway within the buffer cavities 213.

[0040] Specifically, the fixing plate 211 can be a metal plate, which is fixedly installed on the inner surface of the bottom shell 1. A buffer plate 212 is provided above the fixing plate 211. The surface of the buffer plate 212 facing the fixing plate 211 can have multiple notches at intervals to serve as buffer cavities 213. The multiple buffer cavities 213 can be the same shape and evenly distributed, or they can be different shapes and non-uniformly distributed. For example, the multiple buffer cavities 213 can be rectangular and arrayed on the buffer plate 212. In another embodiment, the multiple buffer cavities 213 can all be annular and radially spaced. The specific distribution of the buffer cavities 213 can be designed according to the actual shock absorption effect, and this application does not limit it.

[0041] A buffer ball can be placed in each buffer cavity 213, or a buffer ball can be placed in some buffer cavities 213 while the remaining buffer cavities 213 remain empty. For example, a buffer ball can be placed in one of two adjacent buffer cavities 213 while the other remains empty. The size of the buffer ball is smaller than the size of the buffer cavity 213, so that there is enough space in the buffer cavity 213 for the buffer ball to move.

[0042] By setting a damping section 21 consisting of a fixed plate 211 and a buffer plate 212, when vibration is transmitted to the damping section 21, the buffer balls in the multiple buffer cavities 213 will all shake. As the multiple buffer balls continuously impact the sidewalls of the buffer cavities 213, the disordered movement of the buffer balls can effectively dampen the vibration, thereby improving the damping effect of the damping section 21 and effectively reducing the intensity of vibration transmitted to the bottom shell 1. It should be understood that the specific number of layers of the damping section 21 can be designed according to the actual installation space and damping requirements, and is not limited to a fixed plate 211 and a buffer plate 212 in the example above. That is, in other embodiments, multiple fixed plates 211 can be stacked at intervals, and a buffer plate 212 can be set on each fixed plate 211.

[0043] Optionally, the buffer plate 212 and the buffer ball are made of an elastic material.

[0044] Specifically, to improve both shock absorption and noise reduction, both the buffer plate 212 and the buffer ball are made of elastic materials, such as rubber or silicone. This reduces noise generated when the buffer cavity 213 collides with the buffer plate 212 or the fixed plate 211 during shaking. Simultaneously, the increase in the overall weight of the base shell 1 after adding the buffer plate 212 and the buffer ball is minimal, ensuring that the overall weight of the shock absorber housing is kept within a reasonable range. To further enhance the shock absorption effect, the buffer ball can also be a solid sphere made of steel, with a layer of elastic material, such as rubber or silicone, covering its surface. The specific design can be tailored to the actual shock absorption requirements.

[0045] Optionally, the volume of the buffer ball is 30% to 70% of the volume of the buffer cavity 213.

[0046] Specifically, the volume of the buffer ball should not occupy too much of the buffer cavity 213, so as to avoid insufficient space within the buffer cavity 213 for the buffer ball to shake sufficiently and absorb the vibration amplitude; the volume of the buffer ball should also not be too small, so as to avoid the buffer ball shaking too much and being unable to absorb the vibration amplitude in time, thus reducing the shock absorption effect. The specific volume of the buffer ball can be designed according to the actual volume of the buffer cavity 213.

[0047] While mitigating vibration, the operation of the device also generates noise. Optionally, the bottom shell 1 is provided with multiple sound-absorbing holes 11 spaced apart from the part corresponding to the vibration damping cavity. The vibration damping cavity is also filled with a sound-absorbing layer.

[0048] Specifically, multiple through holes are formed on the surface of the bottom shell 1 as sound-absorbing holes 11. The sound-absorbing holes 11 can be elongated or circular, and their diameters are all small, achieving the effect of perforation sound absorption. To further enhance the sound absorption effect, the damping cavity can also be filled with sound-absorbing cotton or other structures as a sound-absorbing layer, thereby further reducing the possibility of noise transmission to the outside. This allows the damping shell to not only achieve the effect of vibration damping but also the effect of noise reduction.

[0049] The gas water heater includes a burner, a heat exchanger, and a shock-absorbing housing as described above; the burner is located inside the shock-absorbing housing; the heat exchanger is located inside the shock-absorbing housing and uses the heat generated by the burner to heat the water flow.

[0050] During operation, the vibration and noise generated by the burner and heat exchanger of this gas water heater can be effectively mitigated by the shock-absorbing component 2 and the shock-absorbing cavity formed by the shock-absorbing component 2 and the bottom shell 1. As a result, the vibration and noise transmitted to the bottom shell 1 are relatively small, the overall vibration amplitude of the shock-absorbing casing is small, and the noise is weak, ensuring the comfort of users during use. It can also effectively extend the service life of the gas water heater and reduce the possibility of safety hazards.

[0051] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here.
