Description

Technical Field

[0001] The present application relates to the field of household appliance technology, and in particular to a silencer and a steamer. Background Art

[0002] Steam-heated steamers are common cooking appliances in modern kitchens. They offer advantages such as ease of operation and high cooking efficiency, making them widely used in homes and the catering industry. However, existing steam-heated steamers often produce high noise levels during use, primarily due to the water hammer effect.

[0003] Water hammer is a phenomenon in fluid dynamics that primarily occurs in closed systems such as water pipes or steamers. Rapid changes in steam pressure within a steamer, particularly when a heating plate is quickly turned on or off, or when the fluid in the steam pipe suddenly changes its state of motion, can cause the fluid to violently impact the pipe walls or valves, producing a noise similar to a hammer striking a valve. This is known as the water hammer effect.

[0004] Specifically, during the heating process of a steam-heated steamer, steam is continuously generated and accumulated within the confined space, causing the steam pressure to gradually increase. When the steam pressure reaches a certain level, if the steam outlet valve is suddenly opened, the high-pressure steam will flow out rapidly, exerting a huge impact force on the valve and the steamer tube wall in a short period of time, resulting in a loud noise.

[0005] The water hammer effect not only causes noise pollution and affects the user's cooking experience, but may also damage the structure of the steamer and shorten the service life of the equipment. Summary of the Invention

[0006] In view of this, the present application provides a silencer and a steamer, which have a simple structure and a small size and can significantly reduce the noise of steam heating.

[0007] In the first aspect, the present application provides a silencer device, comprising a base and an air outlet cover, wherein the air outlet cover is connected to the base, the base is penetrated by a steam channel, the air outlet cover is penetrated by an air outlet channel, and a silencer is arranged between the steam channel and the air outlet channel, and the steam in the steam channel can communicate with the outside world through the silencer and the air outlet channel.

[0008] By adopting the above technical solution, the base and the outlet cover are securely connected together through some means (such as threaded or snap-fit ​​connections) to form a single, integrated structure. A steam channel is designed within the base to guide the flow of steam. The outlet cover, on the other hand, has an outlet channel extending through it, serving as the final outlet for steam from the device to the outside world. When steam flows through the steam channel and attempts to exit through the outlet channel, it must first pass through the silencer. The structural design of the silencer (such as porous materials or labyrinthine channels) increases the length and complexity of the steam flow path, obstructing the flow, thereby slowing its velocity and dissipating its energy. The silencer effectively suppresses the noise generated by the steam flow, providing a quieter and more comfortable user experience. While slowing the steam flow, the silencer also allows for more efficient heat exchange with the surrounding environment, thereby improving steam utilization efficiency. The silencer device of this application features a simple design and compact structure, making it easy to install and use. Furthermore, its diverse connection methods make it suitable for various types of steam heating equipment. By reducing the noise and impact force during steam flow, the silencer of the present application can also effectively protect the internal structure of the steam heating equipment and extend its service life.

[0009] In some embodiments, a connecting piece is further included, and the air outlet cover is connected to the base via the connecting piece, and the silencer is arranged between the connecting piece and the air outlet cover.

[0010] By adopting the above technical solution, the air outlet cover is connected to the base through a connector. This connection method can more flexibly adjust the relative position between the air outlet cover and the base, thereby ensuring that the silencer can be accurately set between the steam channel and the air outlet channel. The design of the connector can include a variety of structures such as threads, snaps, flanges, etc. to meet the needs of different application scenarios. The shape and size of the internal channel of the connector can optimize the steam flow path to reduce the formation of turbulence and eddies, and further reduce noise. By arranging the silencer between the connector and the air outlet cover, the steam flow path can be more accurately controlled and the silencer effect can be optimized. The design of the connector makes the installation and replacement of the silencer more convenient. The user can fix the silencer in the appropriate position without complicated operations and processes, and also reduces the after-sales maintenance costs.

[0011] In some embodiments, the silencer is a filter, and the air outlet cover and the connector are detachably connected to fix the filter between the air outlet cover and the connector.

[0012] By adopting the above technical solution, the filter is typically made of a porous material, such as metal mesh, plastic mesh, or fiber mesh. These materials have good air permeability and a certain structural strength to withstand the pressure and flow rate of steam. The porous structure of the filter effectively disperses the flow of steam, slowing its flow rate and absorbing some noise. The filter also acts as a filter, removing impurities or particles that may be carried by the steam, ensuring the cleanliness of the outgoing steam. The outlet cover and the connector are connected by a detachable connection, which ensures that the user can easily remove the filter for cleaning or replacement without disassembling the entire silencer. Common detachable connection methods include threaded connections, snap-on connections, and slot connections, all of which are simple in structure and easy to operate. The design of using a filter as a silencer not only provides effective noise suppression, but also is easy to maintain, improves steam quality, and exhibits good flexibility and cost-effectiveness. This design makes the silencer of the present application have a wider application prospect in steam heating equipment.

[0013] In some embodiments, the base is connected to a one-way valve, and the one-way valve is configured to allow the steam channel to flow in a one-way manner toward the gas outlet channel.

[0014] By adopting the above technical solution, the one-way valve can ensure that the steam will not flow back during the flow process. In some high-pressure steam applications, steam backflow may cause safety hazards. The presence of the one-way valve can effectively prevent this from happening and improve the safety of the entire system. The setting of the one-way valve makes the steam flow more smoothly, reduces the turbulence and eddy currents caused by backflow, and helps to further improve the silencer effect. By preventing steam backflow, the one-way valve can ensure that the steam is fully utilized during the flow process, reducing energy waste. The silencer device of the present application further enhances system safety, optimizes steam utilization efficiency, improves silencer effect, and extends service life on the basis of maintaining the original technical effect. This design makes the silencer device have higher reliability and performance in steam heating equipment.

[0015] In some embodiments, the one-way valve includes a weight and a limit member, wherein the limit member is connected to the base and is used to limit the weight from separating from the base, and the weight is used to open the steam channel when the steam pressure in the steam channel reaches a set value, and to close the steam channel when the steam pressure in the steam channel is less than the set value.

[0016] By adopting this technical solution, when the steam pressure in the steam channel reaches the set value, the steam pressure overcomes the gravity of the weight, pushing the weight to move and open the steam channel, allowing steam to flow freely through the steam channel to the exhaust channel. Once the steam pressure in the steam channel drops below the set value, the weight is acted upon by gravity and moves downward, resealing the steam channel and preventing steam from flowing in the opposite direction, thus achieving a one-way flow function. The weight's mass, shape, and size can be adjusted to suit the specific design, increasing application flexibility. The position and shape of the stopper ensure that the weight is not obstructed or damaged during movement. The one-way valve using a combination of a weight and a stopper not only offers the advantages of automatic adjustment, pressure adaptability, and backflow prevention, but also simplifies the structure, reduces costs, and improves maintenance ease. This design enhances the reliability and performance of the silencer in steam heating equipment while reducing the complexity and cost of the overall system.

[0017] In some embodiments, the weight includes a cone and a vertical body connected integrally, the base is provided with a conical surface matching the cone and a cylindrical surface connected to the conical surface, and the vertical body is located in a space surrounded by the cylindrical surface.

[0018] By adopting the above technical solution, the combination of the cone and the conical surface improves the reliability and service life of the one-way valve seal. The pitot part is located in the space surrounded by the cylindrical surface on the base. This space provides a stable guide for the pitot, preventing the weight from shaking or deflecting during movement. At the same time, the design of the pitot can also adjust its mass and size according to actual needs to achieve adaptability to different steam pressures and more precise opening / closing control. The combined structure of the cone and pitot makes the weight more stable during movement, reducing the possibility of shaking or deflection, which not only enhances the functionality and stability of the one-way valve, but also optimizes its structural compactness and adaptability. This design is also easy to manufacture and install, improving production efficiency and convenience of maintenance.

[0019] In some embodiments, an inner sealing ring and an outer sealing ring are connected to the outer periphery of the base and are spaced apart.

[0020] By adopting the above technical solution, the combined use of the inner sealing ring and the outer sealing ring can improve the sealing performance of the connection with the steamer, reduce steam leakage, and ensure efficient and stable cooking of the steamer.

[0021] In some embodiments, the gas outlet channel includes a steam cavity and an air outlet hole that are interconnected. The steam cavity is connected to the steam channel through a silencer, and the air outlet hole is connected to the steam cavity and the outside.

[0022] By adopting this technical solution, the steam chamber design creates a certain pressure gradient within it, promoting smooth steam flow and gradual pressure release. A silencer, positioned between the steam chamber and the steam channel, primarily functions to reduce noise generated during steam flow. The exhaust channel design includes key components such as the steam chamber, silencer, and exhaust port, which work together to ensure smooth steam discharge and effectively reduce noise.

[0023] In some embodiments, in the axial direction of the steam channel, the distance between the end of the air outlet located in the steam cavity and the muffler is greater than the distance between the end of the air outlet away from the steam cavity and the muffler.

[0024] The above technical solution helps the steam heat the water at the bottom of the steamer, improving heating efficiency. It also helps the steam form a certain amount of vortex and buffer in the steam chamber, allowing the steam to fully diffuse and slow down before flowing out of the outlet, thereby reducing noise generation.

[0025] In a second aspect, the present application provides a steamer comprising the silencer device described in the first aspect.

[0026] Because the steamer integrates an efficient silencer, it reduces the noise generated during the steaming process, providing users with a quieter and more comfortable cooking environment. This steamer not only retains the steaming function of traditional steamers but also achieves significant improvements in noise reduction. The steamer provided in this application successfully achieves the dual goals of noise reduction and efficient steaming by cleverly incorporating a silencer. This steamer not only provides users with a superior cooking experience but also promotes innovation and development in steamer technology.

[0027] In summary, this application has at least one of the following beneficial technical effects:

[0028] 1. The silencer device of this application effectively reduces the noise of steam heating water, providing users with a quieter and more comfortable use environment.

[0029] 2. The silencer device of the present application has a simple design and a compact structure, and is easy for users to install and use.

[0030] 3. The steamer is integrated with a high-efficiency silencer, which reduces the noise generated by the steamer during the steaming process. It not only retains the steaming function of the traditional steamer, but also makes significant progress in noise reduction. BRIEF DESCRIPTION OF THE DRAWINGS

[0043] The following is a detailed description of the embodiments of the present invention in conjunction with the accompanying drawings. In the absence of conflict, the features of the following embodiments can be combined with each other.

[0044] Example 1

[0045] See also Figures 1-4 The silencer 100 provided in an embodiment of the present application includes a detachably connected base 1, a connector 3, and an air outlet cover 2. The air outlet cover 2 is threadedly connected to the connector 3, which is in turn threadedly connected to the base 1. The base 1 is connected to an inner sealing ring 4 and an outer sealing ring 5, spaced apart from each other. When assembled with a steamer, the steamer liner 9 is positioned between the inner sealing ring 4 and the outer sealing ring 5. The silencer 100 and the steamer liner 9 are fixedly connected as one by tightening the base 1 and the connector 3.

[0046] Refer to Figures 2 and 3. A steam channel 11 extends through the base 1, and an outlet channel extends through the outlet cover 2. A silencer is provided between the steam channel 11 and the outlet channel. The steam within the steam channel 11 can communicate with the outside world through the silencer and the outlet channel, effectively reducing the noise emitted by steam. The outlet channel includes a steam chamber 21 and an outlet hole 22, which are interconnected. The outlet hole 22 connects the steam chamber 21 with the outside world. The silencer in this embodiment is a filter 6. The connector 3, filter 6, and base 1 enclose a buffer chamber 31, which can buffer and reduce the noise of steam entering the steam chamber 21 from the steam channel 11.

[0047] In the axial direction of the steam channel 11 , the distance between the end of the air outlet 22 located in the steam cavity 21 and the muffler is greater than the distance between the end of the air outlet 22 away from the steam cavity 21 and the muffler.

[0048] The base 1 is connected to a one-way valve, which is configured to unidirectionally conduct the steam channel 11 toward the air outlet channel. The one-way valve includes a weight 7 and a limiter, the limiter is connected to the base 1 and is used to limit the weight 7 from separating from the base 1, and the weight 7 is used to open the steam channel 11 when the steam pressure in the steam channel 11 reaches a set value, and to close the steam channel 11 when the steam pressure in the steam channel 11 is less than the set value. Specifically, the one-way valve can be a valve body made of metal material, which is provided with a movable part, such as a spring or a weight 7, for controlling the flow direction of steam. The shape of the one-way valve can be round, square or other shapes suitable for installation on the base 1. The one-way valve can be connected to the base 1 by threads, snaps or other connection methods to form a stable connection structure.

[0049] The one-way valve works as follows: when the steam pressure in steam passage 11 exceeds a certain value, the movable component (e.g., weight 7) is pushed open, allowing steam to pass smoothly through the one-way valve into the outlet passage. When the steam pressure in steam passage 11 drops below a certain value, the movable component automatically closes, preventing external air from flowing back into steam passage 11.

[0050] When steam enters the silencer 100 through the steam channel 11, it first passes through the control of the one-way valve. Only when the steam pressure in the steam channel 11 exceeds a certain value can the steam enter the air outlet channel. Then, the steam passes through the filtering and sound absorption of the silencer, most of the sound waves are absorbed, and the remaining small amount of sound waves are discharged through the air outlet channel. Due to the presence of the one-way valve and the silencer, the noise generated during steam discharge is greatly reduced, and the comfort and safety of the working environment are improved. In addition, the design of the one-way valve can effectively prevent steam backflow, avoid equipment damage and other safety hazards caused by steam backflow, extend the service life of the equipment, reduce maintenance costs, and improve overall production efficiency.

[0051] The limiting member in this embodiment is a clip 8 , which is clamped to one end of the base 1 close to the filter 6 . The clip 8 can limit the weight 7 from escaping from the end close to the filter 6 .

[0052] Specifically, base 1 can be made of a metal material, such as stainless steel or aluminum alloy, to ensure high-temperature and corrosion resistance. Base 1 can be cylindrical or other shapes suitable for installation on steam equipment. Steam channel 11 runs through base 1, and its diameter can be adjusted to accommodate different steam flow rates based on the actual application scenario.

[0053] The outlet cover 2 can also be made of metal, such as stainless steel or aluminum alloy, to ensure its strength and durability. The outlet cover 2 is connected to the base 1 via threads, snaps, or other fastening methods. This connection method facilitates assembly and disassembly, facilitating maintenance and replacement of silencers. The outlet cover 2 can be round, square, or other shapes suitable for installation on steam equipment to accommodate various installation spaces.

[0054] The silencer is arranged between the air outlet cover 2 and the base 1, and is clamped and fixed by a threaded connection between the air outlet cover 2 and the base 1. The silencer can be a filter 6, a porous material or sound-absorbing cotton, etc. The filter 6 can be made of a metal wire mesh or a nylon mesh, and has good air permeability and sound absorption effect. The porous material can be ceramic or porous metal, and the microporous structure inside it can effectively absorb sound waves. The sound-absorbing cotton can be made of glass fiber or polyester fiber, and has good sound absorption performance. The thickness and aperture of the filter 6 can be adjusted according to the actual application scenario to adapt to different steam flow rates and noise levels. The shape of the filter 6 can be round, square or other shapes suitable for installation between the air outlet cover 2 and the connector 3.

[0055] The operating principle of this embodiment is as follows: when steam enters the silencer 100 through the steam passage 11, it first passes through the buffer chamber 31 to buffer the temperature and steam. The filtration and sound absorption effects of the silencer then enter the steam chamber 21 for further noise reduction. The steam is then discharged from the air outlet 22 to heat the water outside the silencer 100. The silencer 100 reduces the noise generated by the water hammer effect during steam heating of the water, improving the comfort and safety of the working environment. Furthermore, the material selection and structural design of the base 1 and air outlet cover 2 provide excellent high-temperature and corrosion resistance, extending the service life of the equipment, reducing maintenance costs, and improving overall production efficiency.

[0056] Example 2

[0057] The difference between this embodiment and the above embodiments is that there is no one-way valve in the base 1, which can reduce costs in practical applications.

[0058] Example 3

[0059] Please refer to Figure 4 The difference between this embodiment and the above embodiment is that the one-way valve includes a weight 7 and a limiter, the limiter is used to limit the weight 7 from separating from the base 1, the weight 7 is used to open the steam channel 11 when the steam pressure in the steam channel 11 reaches a set value, and close the steam channel 11 when the steam pressure in the steam channel 11 is less than the set value.

[0060] Specifically, the weight 7 can be a metal block of a certain mass, shaped like a cone 71, a sphere, or other shapes suitable for installation within the one-way valve. The surface of the weight 7 can be polished to reduce friction and improve response speed. The stopper can be a fixed baffle or stop pin, which limits the range of movement of the weight 7 and prevents it from separating from the base 1. The stopper can be made of metal or plastic to adapt to different usage environments.

[0061] The weight 7 comprises an integrally connected cone 71 and a drop 72. The base 1 is provided with a conical surface 12 that mates with the cone 71 and a cylindrical surface 13 connected to the cone 12. The drop 72 is positioned within the space surrounded by the cylindrical surface 13 for movement and guidance. This design allows the weight 7 to open rapidly when the steam pressure in the steam passage 11 reaches a set value, and to close rapidly when the steam pressure falls below the set value, thereby effectively controlling the flow of steam.

[0062] The advantage of this embodiment is that the weight of the weight hammer 7 can be adjusted by installing vertical bodies 72 of different weights on the cone 71, thereby adjusting the conduction pressure value of the one-way valve.

[0063] Example 4

[0064] The difference between this embodiment and the above embodiments is that the air outlet cover 2 and the connecting member 3 are integrated into one piece, which can simplify the structure and reduce the assembly process and cost.

[0065] Example 5

[0066] See also Figure 5 and Figure 6 , an embodiment of the present application provides a steamer, comprising a silencer 100 as described in any of the aforementioned embodiments.

[0067] See also Figure 6 The steamer's bottom 91 is clamped and fixedly connected to the base 1 via a connector 3. The inner sealing ring 4 abuts the inner surface of the bottom 91, while the outer sealing ring 5 abuts the outer surface of the bottom 91, achieving a seal. Steam generated by the steam generator enters the silencer 100 through the steam passage 11 and is discharged from the outlet 22 of the outlet cover 2 into the inner pot 9, where it exchanges heat with the water inside. This effectively reduces the noise caused by the water hammer effect.

Those skilled in the art should understand that the present invention is not limited to the foregoing embodiments, which are merely illustrative of the principles of the present invention.
