Description

Cooking utensils and sound-absorbing components Technical Field

[0001] This utility model belongs to the field of cooking equipment technology, and specifically provides a cooking utensil and a sound-absorbing component. Background Technology

[0002] Existing cooking equipment often needs to release internal gases before, during, or after cooking. For example, negative pressure cooking equipment typically requires a vacuum pump to create a vacuum inside before cooking, thereby lowering the cooking temperature, preserving the nutrients in the food, and improving its texture. Similarly, pressure cookers need to release the high-pressure gases from inside the pot through a vent valve after cooking.

[0003] However, regardless of the type of cooking equipment, significant wind noise is generated during the exhaust process, especially when the exhaust flow is large, which affects the user experience. Summary of the Invention

[0004] One objective of this invention is to solve the problem of excessive wind noise when venting existing cooking appliances.

[0005] To achieve the above objectives, the present invention provides a cooking utensil in a first aspect, comprising:

[0006] The body has a cooking cavity;

[0007] The lid is used to open and close the cooking chamber, and the lid is provided with an exhaust channel for venting the gas inside the cooking chamber;

[0008] A noise-reducing component is embedded in the exhaust channel and, together with the peripheral wall of the exhaust channel, defines the noise-reducing channel. The flow area of ​​the noise-reducing channel alternately increases and decreases, so that the gas flow velocity repeatedly increases and decreases multiple times, thereby reducing wind noise.

[0009] Optionally, the silencing component includes multiple large-diameter segments and multiple small-diameter segments, with a small-diameter segment disposed between two adjacent large-diameter segments, so that the large-diameter segments and the small-diameter segments are alternately distributed; the large-diameter segments and the peripheral wall of the exhaust channel define an annular gap that allows gas to flow through; the small-diameter segments and the peripheral wall of the exhaust channel define an annular cavity that allows gas to flow through; the annular gap and the annular cavity constitute at least a part of the silencing channel.

[0010] Optionally, the outer periphery of both ends of the large-diameter section is rounded.

[0011] Optionally, the two outermost large-diameter segments in the axial direction among the plurality of large-diameter segments are referred to as end large-diameter segments; the muffler is provided with a connecting part, a snap-fit ​​part, and an operating part in sequence on the side of one of the end large-diameter segments away from the small-diameter segments; the cover is provided with an annular flange extending into the exhaust channel, the snap-fit ​​part and the operating part pass through the annular flange, the connecting part has a gap with the annular flange, and the snap-fit ​​part and the end large-diameter segment interfere with the annular flange respectively to fix the muffler to the exhaust channel.

[0012] Optionally, the annular flange is provided with a rib on the side facing the snap-fit ​​portion to abut against the snap-fit ​​portion, so that gas can flow through the gap between the rib, the annular flange and the snap-fit ​​portion; or, the snap-fit ​​portion is provided with multiple grooves on the side facing the connecting portion.

[0013] Optionally, the snap-fit ​​portion has a guide cone surface on the side away from the connecting portion, so that the snap-fit ​​portion passes through the annular flange by means of the guide cone surface; and / or, the operating portion is configured as a rod-shaped structure, and its diameter is smaller than the inner diameter of the annular flange.

[0014] Optionally, the noise-reducing component is a component made of an elastic material.

[0015] Optionally, the elastic material is silicone or polyurethane.

[0016] Optionally, the cooking appliance also includes a vacuum pump mounted on the lid, the outlet of which is connected to the exhaust channel to discharge the gas in the cooking chamber to the outside, thereby providing a negative pressure cooking environment for the cooking chamber.

[0017] The present invention provides a noise reduction component in a second aspect, which is the noise reduction component described in any one of the first aspects.

[0018] Based on the foregoing description, those skilled in the art will understand that in the aforementioned technical solution of this utility model, by embedding a sound-absorbing component within the exhaust channel of the cooking appliance, and by having the sound-absorbing component and the peripheral wall of the exhaust channel jointly define the sound-absorbing channel, and by alternately increasing and decreasing the flow area of ​​the sound-absorbing channel, the gas flow velocity can be repeatedly increased and decreased multiple times, effectively reducing wind noise. Therefore, the cooking appliance of this utility model effectively reduces wind noise and improves the user experience.

[0019] Furthermore, by having the silencing component have alternating large-diameter and small-diameter sections, and thus defining alternating annular gaps and annular cavities with the peripheral wall of the exhaust channel, the gas can be alternately compressed and expanded as it flows through the annular gaps and annular cavities, increasing the turbulence of sound propagation, thereby allowing some sound waves to cancel each other out and reducing wind noise.

[0020] Furthermore, by configuring the silencing component with a connecting part, a snap-fit ​​part, and an operating part, not only is the silencing component fixed, but the installation of the silencing component is also facilitated.

[0021] Furthermore, by providing a rib on the side of the annular flange facing the snap-fit ​​part axially, or by providing multiple grooves on the side of the snap-fit ​​part facing the connection part, the flow of gas in the exhaust channel is ensured.

[0022] Furthermore, by setting the sound-absorbing component to be made of elastic material, not only is the installation of the sound-absorbing component easier, but the elasticity of the sound-absorbing component itself can also absorb a certain amount of sound waves, thereby further reducing wind noise.

[0039] Those skilled in the art should understand that the embodiments described below are merely some embodiments of the present invention, and not all embodiments of the present invention. These embodiments are intended to explain the technical principles of the present invention and are not intended to limit the scope of protection of the present invention. Based on the embodiments provided by the present invention, all other embodiments obtained by those skilled in the art without creative effort should still fall within the scope of protection of the present invention.

[0040] It should be noted that in the description of this utility model, terms such as "center," "upper," "lower," "top," "bottom," "left," "right," "vertical," "horizontal," "inner," and "outer," which indicate direction or positional relationships, are based on the direction or positional relationships shown in the accompanying drawings. These are used merely for ease of description and do not indicate or imply that the corresponding device or element must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0041] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances. For example, unless otherwise specified, the terms "installation," "connection," "joining," and "fixing" can specifically refer to any feasible connection form such as bolt connection, screw connection, welding, insertion, riveting, fusion welding, or snap-fit.

[0042] As shown in Figures 1 and 2, in some embodiments of this utility model, the cooking appliance 001 includes a body 100 and a lid 200. The body 100 has a cooking cavity 101, and the lid 200 is used to open and close the cooking cavity 101. The body 100 is also provided with a lid opening button 110, so that the closed lid 200 can be opened by pressing the lid opening button 110.

[0043] As shown in Figure 1, in some embodiments of this utility model, the cover 200 is provided with an exhaust port 201 to discharge the gas in the cooking cavity 101.

[0044] As shown in Figure 3, in some embodiments of this utility model, the cooking appliance 001 further includes an exhaust adapter 310, a one-way valve 320, and a vacuum pump 330. The exhaust adapter 310 is connected to the exhaust port 201, and the exhaust adapter 310 is connected to the one-way valve 320 through a pipe 340. The one-way valve 320 is connected to the vacuum pump 330 through a pipe 340, so that when the vacuum pump 330 is working, the gas in the cooking chamber 101 is discharged to the outside, providing a negative pressure cooking environment for the cooking chamber 101.

[0045] The one-way valve 320 is used to prevent gas from flowing back into the cooking chamber 101.

[0046] Furthermore, provided that gas backflow into the cooking chamber 101 can be avoided, those skilled in the art may omit the one-way valve 320 as needed, for example, by integrating the vacuum pump 330 with a one-way exhaust module.

[0047] Referring again to Figure 3, in some embodiments of this utility model, the cooking appliance 001 further includes a solenoid valve 350. This solenoid valve 350 is connected to the exhaust adapter 310 via a pipe 340 and is also connected to the outside via the pipe 340. The solenoid valve 350 has an open state and a closed state. When the solenoid valve 350 is in the open state, gas cannot flow through it. When the solenoid valve 350 is in the closed state, gas can flow through it.

[0048] Those skilled in the art will understand that after cooking is finished, the air pressure inside the cooking chamber 101 may be low, causing the lid 200 to be unable to open due to atmospheric pressure. At this time, the solenoid valve 350 is opened to allow outside air to enter the cooking chamber 101 through the solenoid valve 350, so that the air pressure inside the cooking chamber 101 is consistent with the outside atmospheric pressure, thereby ensuring that the lid 200 can be opened smoothly.

[0049] Furthermore, the vacuum pump 330 does not operate when the cooking appliance 001 is performing high-pressure cooking. After cooking is complete, the cooking chamber 101 can also be depressurized via the solenoid valve 350.

[0050] Of course, in other embodiments of this utility model, those skilled in the art may omit the solenoid valve 350 and its associated pipeline 340 as needed.

[0051] As shown in Figures 4 and 5, in some embodiments of this utility model, an exhaust channel 202 is provided on the cover 200, which is used to exhaust gas from the cooking chamber 101. Specifically, the exhaust channel 202 is connected to the vacuum pump 330 through a pipe 340, so that the gas discharged by the vacuum pump 330 enters the outside through the exhaust channel 202.

[0052] Referring again to Figures 4 and 5, in some embodiments of this utility model, the cooking appliance 001 further includes a noise-reducing component 400. This noise-reducing component 400 is embedded in the exhaust channel 202 and, together with the peripheral wall of the exhaust channel 202, defines a noise-reducing channel 203. The flow area of ​​the noise-reducing channel 203 alternately increases and decreases, causing the gas flow rate to repeatedly increase and decrease multiple times, thereby reducing wind noise.

[0053] In addition, in other embodiments of this utility model, those skilled in the art may also, as needed, configure an exhaust channel 202, a silencing component 400, and a silencing channel 203 downstream of the solenoid valve 350.

[0054] As shown in Figures 5 to 7, in some embodiments of this utility model, the noise-absorbing component 400 includes a plurality of large-diameter segments 410 and a plurality of small-diameter segments 420, with a small-diameter segment 420 disposed between two adjacent large-diameter segments 410, so that the large-diameter segments 410 and the small-diameter segments 420 are alternately distributed.

[0055] As can be seen from Figures 5 to 7, the large-diameter section 410 and the peripheral wall of the exhaust channel 202 define an annular gap 2031 through which gas can flow.

[0056] As can be seen from Figures 5 to 7, the small diameter section 420 and the peripheral wall of the exhaust channel 202 define an annular cavity 2032 through which gas can flow.

[0057] As can be seen from Figures 5 and 7, the annular gap 2031 and the annular cavity 2032 constitute at least a part of the silencing channel 203.

[0058] Those skilled in the art will understand that by having the silencing member 400 have alternating large-diameter sections 410 and small-diameter sections 420, and thus defining alternating annular slits 2031 and annular cavities 2032 with the peripheral wall of the exhaust passage 202, the gas can be alternately compressed and expanded as it flows through the annular slits 2031 and annular cavities 2032, increasing the turbulence of sound propagation, thereby allowing some sound waves to cancel each other out and reducing wind noise.

[0059] As can be seen from Figure 6, in some embodiments of this utility model, the outer periphery of both ends of the large diameter section 410 is rounded 4101 to prevent sharp edges from obstructing gas flow and causing wind noise.

[0060] As shown in Figure 6, in some embodiments of this utility model, the two outermost large-diameter segments 410 in the axial direction among the plurality of large-diameter segments 410 are referred to as end large-diameter segments 411. The noise-reducing member 400 has a connecting part 430, a snap-fit ​​part 440 and an operating part 450 sequentially provided on the side of one end large-diameter segment 411 (the end large-diameter segment 411 on the top side in Figure 6) away from the small-diameter segment 420.

[0061] As shown in Figure 6, in some embodiments of this utility model, the cover 200 is provided with an annular flange 210 extending into the exhaust channel 202. The snap-fit ​​portion 440 and the operating portion 450 pass through the annular flange 210, and a gap 204 exists between the connecting portion 430 and the annular flange 210. The snap-fit ​​portion 440 and the large-diameter end section 411 interfere with the annular flange 210, in other words, the diameters of the snap-fit ​​portion 440 and the large-diameter end section 411 are both larger than the inner diameter of the annular flange 210, so as to fix the muffler 400 into the exhaust channel 202.

[0062] As shown in Figure 6, a guide cone surface 441 is provided on the side of the snap-fit ​​portion 440 away from the connecting portion 430, so that the snap-fit ​​portion 440 passes through the annular flange 210 with the help of the guide cone surface 441. The operating portion 450 is configured as a rod-shaped structure, and its diameter is smaller than the inner diameter of the annular flange 210, so as to pass smoothly through the annular flange 210.

[0063] Those skilled in the art will understand that when installing the silencer component 400, the operating part 450 can be passed through the annular flange 210 first, and then the operating part 450 can be pulled forcefully so that the locking part 440 also passes through the annular flange 210. Finally, the pipe 340 connected to the vacuum pump 330 is inserted into the peripheral wall of the exhaust channel 202.

[0064] As can be seen from Figures 5 and 6, the peripheral wall of the top of the exhaust passage 202 extends along the upper side in Figure 5 so that the pipe 340 can be fitted onto the top of the exhaust passage 202.

[0065] Furthermore, in other embodiments of this utility model, those skilled in the art can, as needed, configure the operating part 450 as any other feasible structure, such as a pull rope. Alternatively, those skilled in the art can, as needed, omit the operating part 450 and allow the locking part 440 to pass through the annular flange 210 by pressing the silencing member 400 upward.

[0066] As shown in Figures 5 and 7, in some embodiments of this utility model, a rib 211 is provided on the side of the annular flange 210 facing the snap-fit ​​portion 440 to abut against the snap-fit ​​portion 440, so that gas can flow through the gap between the rib 211, the annular flange 210 and the snap-fit ​​portion 440.

[0067] As can be seen from Figure 7, in some embodiments of this utility model, the distance between the large-diameter end section 411 and the snap-fit ​​portion 440 is greater than the sum of the thicknesses of the annular flange 210 and the rib 211, so that gas can flow smoothly between the annular flange 210 and the large-diameter end section 411.

[0068] Those skilled in the art will understand that, under the influence of gravity and the pressure of the gas discharged from the vacuum pump 330, the snap-fit ​​portion 440 will adhere tightly to the rib 211, thereby creating an airflow gap between the annular flange 210 and the large-diameter end section 411.

[0069] Furthermore, in some embodiments of this utility model, the sound-absorbing component 400 is made of an elastic material. This not only facilitates the installation of the sound-absorbing component 400, but also allows the elasticity of the component 400 itself to absorb a certain amount of sound waves, thereby further reducing wind noise.

[0070] The elastic materials include silicone, polyurethane, and rubber.

[0071] Based on the foregoing description, those skilled in the art will understand that the cooking appliance 001 of this utility model reduces wind noise during exhaust by configuring the sound-absorbing component 400, thereby improving the user experience; moreover, the sound-absorbing component 400 has a simple structure and is easy to install, effectively reducing production costs.

[0072] Furthermore, those skilled in the art can make appropriate adjustments to the technical solution of this utility model based on some of the embodiments described above. However, such adjustments will not deviate from the technical principles and concepts of this utility model and should still fall within the protection scope of this utility model.

[0073] As shown in Figure 8, in some other embodiments, the snap-fit ​​portion 440 is provided with a plurality of grooves 431 on the side facing the connecting portion 430. The grooves 431 extend radially from the outer peripheral surface of the snap-fit ​​portion 440 to the connecting portion 430, so as to ensure that gas can flow smoothly through the annular flange 210 through the grooves 431 even when there are no ribs 211 on the annular flange 210.

[0074] The technical solution of this utility model has been described in conjunction with several embodiments above. However, it will be readily understood by those skilled in the art that the protection scope of this utility model is not limited to these specific embodiments. Without departing from the technical principles of this utility model, those skilled in the art can disassemble and combine the technical solutions in the above embodiments, and can also make equivalent changes or substitutions to the relevant technical features. Any changes, equivalent substitutions, improvements, etc., made within the technical concept and / or technical principles of this utility model will fall within the protection scope of this utility model.

[0075] Finally, it should be noted that in this invention, the term "connection" refers to fluid communication, allowing fluid (e.g., air, liquid) to flow between two interconnected entities. Furthermore, this "connection" can be either a leak-free flow of fluid between two interconnected entities, or a flow with slight leakage between two interconnected entities.
