Description

Technical Field

[0001] The utility model relates to the field of household appliances, in particular to a sound insulation device and a cooking appliance. Background Art

[0002] In existing cooking appliances, such as an electric slow cooker, it includes a heating base, a cooking pot body and an inner pot. The inner pot is located inside the cooking pot body. The heating base heats the liquid inside the cooking pot body and heats the food ingredients inside the inner pot through the liquid, so as to realize heating the food ingredients inside the inner pot.

[0003] When the electric slow cooker is working, there is a large temperature difference on the heating surface of the electric hot plate, and local subcooled boiling occurs to generate a large number of bubbles. During the rising process of the bubbles, they are blocked by the pad rack and the slow cooker. The small bubbles coalesce to form large bubbles. Finally, the large bubbles break after floating out of the water surface, generating a large noise of bubble breaking. At the same time, the impact force generated by the bubble breaking acts on the slow cooker, causing the slow cooker to generate shaking noise, which affects the user experience. Summary of the Utility Model

[0004] In view of this, it is necessary to provide a sound insulation device and a cooking appliance for the above problems, so as to reduce the outward dissipation of noise generated when the cooking appliance is working.

[0005] The utility model provides a sound insulation device for a cooking appliance. The cooking appliance includes a lid body, and the top wall of the lid body has an air outlet hole communicating with the outside. The sound insulation device includes: a box body, including a bottom wall and a side wall, the bottom wall and the side wall enclose a cavity with an open mouth, and the box body is used to be arranged on the inner wall surface of the lid body and the open mouth of the box body is correspondingly arranged with the air outlet hole; and a plurality of through holes, the through holes are arranged on the side wall.

[0006] The top wall of the lid body of the cooking appliance is provided with an air outlet hole. When noise occurs inside the cooking appliance, it will be transmitted through this air outlet hole. The sound insulation device involved in this application is used to be installed at the air outlet hole of the lid body. Since a plurality of through holes are all arranged on the side wall of the box body, noise cannot escape outward through the bottom wall, and can only escape outward through the through holes arranged on the side wall, the cavity and the air outlet hole in sequence, so as to isolate part of the noise waves escaping towards the bottom wall; since energy loss will occur when the noise passes through the through holes, part of the noise waves escaping towards the side wall can be attenuated, so as to reduce the outward dissipation of noise generated when the cooking appliance is working, enabling the sound insulation device to play a role in noise reduction and sound insulation, and improving the user experience.

[0007] In one embodiment, the flow area of each through hole on the outer wall surface of the side wall is larger than the flow area of the through hole on the inner wall surface of the side wall.

[0008] With such a setting, the flow area of the through hole on the outer wall surface of the side wall is larger than that on the inner wall surface of the side wall, which is beneficial to increasing the energy loss when noise passes through the through hole and further improving the noise reduction effect.

[0009] In one embodiment, along the thickness direction of the side wall, the flow area of the through hole gradually decreases from the outer wall surface of the side wall towards the inner wall surface of the side wall.

[0010] With such a setting, energy loss can be continuously generated when noise passes through the through hole, thereby improving the attenuation effect on the noise wave escaping towards the side wall.

[0011] In one embodiment, when the sound absorption device is installed at the air outlet of the cover body, each through hole has a central axis, and an included angle α is formed between the central axis and the horizontal plane, satisfying: 0° ≤ α ≤ 45°.

[0012] With such a setting, the noise wave along the vertical direction can be reduced from escaping through the through hole.

[0013] In one embodiment, a plurality of the through holes are arranged along the circumferential direction of the side wall.

[0014] With such a setting, the plurality of through holes are arranged along the circumferential direction of the side wall, which is beneficial to further improving the noise reduction effect.

[0015] In one embodiment, it further includes a water leakage hole, and the water leakage hole is opened on the side wall and close to the bottom wall.

[0016] With such a setting, the condensed water generated in the cavity can be discharged from the box body through the water leakage hole, and the water leakage hole arranged on the side wall can prevent noise from escaping through the bottom wall.

[0017] In one embodiment, the bottom end of any through hole is not lower than the top end of the water leakage hole.

[0018] With such a setting, it can be ensured that all the through holes on the side wall will not be blocked by condensed water, avoiding affecting the noise reduction and sound absorption effect of the sound absorption device due to the blockage of the through holes by condensed water.

[0019] In one embodiment, the box body is a silica gel part.

[0020] With such a setting, the silica gel part has the characteristics of a loose molecular structure and porosity, and can effectively isolate the propagation of noise waves, thereby improving the noise reduction and sound absorption effect of the sound absorption device.

[0021] In one embodiment, the sound absorption device further includes a plurality of fixing parts, and the plurality of fixing parts are arranged at intervals along the circumferential direction of the top end of the side wall for fixing with the cover body.

[0022] With such a setting, it is beneficial to fix the sound insulation device on the cover body through the fixing member.

[0023] The present utility model also provides a cooking appliance, including: a pot body; a cover body provided with an air outlet on the top wall thereof, the cover body and the pot body enclosing a cooking cavity; and the sound insulation device located in the cooking cavity, the top end of the side wall being attached to the inner wall surface of the cover body, and the air outlet corresponding to the open mouth of the box body.

[0024] With such a setting, it is avoided that noise escapes through the gap between the side wall and the inner wall surface of the cover body, thus affecting the noise reduction and sound insulation effect of the sound insulation device.

[0025] In one embodiment, the upper edge of the pot body has a receiving portion, the cover body is provided with a blocking portion and a lapping portion, the lapping portion and the blocking portion form a step, the blocking portion extends downward from the lower edge of the cover body, and the lapping portion is lapped on the receiving portion.

[0026] With such a setting, the blocking portion extends downward from the lower edge of the cover body, which can block the gap between the lapping portion and the receiving portion, improve the sealing performance between the cover body and the pot body, and thus reduce the noise generated in the cooking cavity from escaping outward through the gap between the cover body and the pot body, enhancing the user experience.

[0027] In one embodiment, the receiving portion is a groove, the blocking portion is located in the groove, and the lapping portion is lapped on the edge of the groove.

[0028] With such a setting, the inner and outer side walls of the groove and the blocking portion can isolate part of the noise waves; and the noise needs to turn multiple times between the groove and the blocking portion before it can possibly escape outward through the gap between the edge of the groove and the lapping portion, causing energy loss of the noise and attenuating part of the noise waves.

Specific embodiments

[0038] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0039] It should be noted that when a component is referred to as "installed on" another component, it can be directly on the other component or there can also be an intermediate component. When a component is considered to be "arranged on" another component, it can be directly arranged on the other component or there may be an intermediate component at the same time. When a component is considered to be "fixed to" another component, it can be directly fixed to the other component or there may be an intermediate component at the same time.

[0040] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the technical field to which the present invention belongs. The terms used in the description of the present invention herein are only for the purpose of describing specific embodiments, and are not intended to limit the present invention. The term "or / and" used herein includes any and all combinations of one or more of the related listed items. In the present invention, "a plurality" includes two.

[0041] In existing cooking appliances, such as electric slow cookers, they include a heating base, a cooking pot body, and an inner pot. The inner pot is located inside the cooking pot body. The heating base heats the liquid inside the cooking pot body and then heats the ingredients inside the inner pot through the liquid, thereby achieving the heating of the ingredients inside the inner pot. When the electric slow cooker is working, there is a large temperature difference on the heating surface of the electric hot plate, and local subcooled boiling occurs, generating a large number of bubbles. During the rising process of the bubbles, they are blocked by the pad rack and the slow cooker, and the small bubbles coalesce to form large bubbles. Finally, when the large bubbles float to the water surface and break, it generates a relatively large noise from the bubble breakage. At the same time, the impact force generated by the bubble breakage acts on the slow cooker, causing the slow cooker to generate shaking noise, which affects the user experience.

[0042] To solve the above problems, as Figures 1 to 8 shown, the present application provides a sound insulation device 10 and a cooking appliance applying the sound insulation device 10 to reduce the outward dissipation of noise generated when the cooking appliance is working.

[0043] The sound insulation device 10 of the present application is applied to a cooking appliance. The cooking appliance includes a pot body 20 and a lid body 30. The lid body 30 covers the pot body 20 to enclose a cooking cavity 40 with the pot body 20. An air outlet hole 31 communicating with the outside is provided on the top wall of the lid body 30, and the cooking cavity 40 is communicated with the outside through the air outlet hole 31. It is worth mentioning that for an electric slow cooker or an electric slow cooker, an inner pot and an inner lid covering the inner pot will be placed in the cooking cavity. The lid body 30 refers to the outer lid body cooperating with the pot body 20, rather than the inner lid cooperating with the inner pot. When noise occurs in the cooking cavity, the noise will be transmitted out through the air outlet hole 31, affecting the user experience.

[0044] When the sound insulation device 10 is installed on the lid body 30, the generated noise will first pass through the sound insulation device and then be transmitted out through the air outlet hole 31. And through the noise reduction of the sound insulation device 10, it is beneficial to reduce the noise, thereby improving the user experience.

[0045] Specifically, as Figures 2 to 3 shown, specifically, the sound insulation device 10 is used to be installed at the air outlet hole 31 of the lid body 30. The sound insulation device 10 includes a box body 11 and a plurality of through holes 13, where: the box body 11 includes a bottom wall 111 and a side wall 112. The bottom wall 111 and the side wall 112 enclose a cavity 113 with an open mouth. The box body 11 is used to be arranged on the inner wall surface of the lid body 30 and the open mouth of the box body 11 is correspondingly arranged with the air outlet hole; a plurality of through holes 13 are arranged on the side wall 112.

[0046] In the sound insulation device 10 provided by the present utility model, since the air outlet 31 is provided on the top wall of the cover body 30, when the box body 11 is arranged on the cover body 30, the gas generated in the cooking appliance needs to be discharged from the cooking appliance through the through holes 13, the cavity 113 and the air outlet 31 on the side wall 112 in sequence; since a plurality of through holes 13 are all arranged on the side wall 112 of the box body 11, therefore, the noise generated in the cooking appliance due to the bubble breakage or the shaking of the stew pot cannot escape outward through the bottom wall 111, and can only escape outward through the through holes 13, the cavity 113 and the air outlet 31, so that at least part of the noise waves escaping towards the bottom wall 111 can be isolated; in addition, when the noise passes through the through holes 13, energy loss will also occur, so as to attenuate the noise waves escaping towards the side wall 112, thereby reducing the outward escape of the noise generated when the cooking appliance works, so that the sound insulation device 10 can play a role in noise reduction and sound insulation, and improve the user experience.

[0047] As Figure 3 shown, the flow area of each through hole 13 on the outer wall surface of the side wall 112 is larger than the flow area of the through hole 13 on the inner wall surface of the side wall 112. In this way, the energy loss generated when the noise passes through the through holes 13 can be further increased, so as to attenuate more noise waves escaping towards the side wall 112, thereby reducing the outward escape of the noise generated when the cooking appliance works, and further reducing the noise reduction effect of the sound insulation device 10.

[0048] As Figure 2 and Figure 4 shown, since the air outlet 31 of the cooking appliance is opened on the top wall of the cover body 30, therefore, the fixing member 12 can fix the box body 11 on the cover body 30, the bottom wall 111 can isolate part of the noise waves in the vertical direction, and the side wall 112 can attenuate part of the noise waves in the horizontal direction. Among them, the noise waves in the vertical direction refer to the noise waves that propagate roughly in the vertical direction, and their propagation direction can be completely along the vertical direction or form a small angle with the vertical direction; the noise waves in the horizontal direction refer to the noise waves that propagate roughly in the horizontal direction, and their propagation direction can be completely along the horizontal direction or form a small angle with the horizontal direction. Since most of the noise generated by the bubble breakage in the cooking appliance propagates from bottom to top, therefore, isolating part of the noise waves in the vertical direction through the bottom wall 111 can further reduce the outward escape of the noise generated when the cooking appliance works.

[0049] As Figure 3As shown, in one embodiment, the through hole 13 is circular in any cross section parallel to the side wall 112. The opening diameter of the through hole 13 on the outer wall surface of the side wall 112 is D, and the opening diameter of the through hole 13 on the inner wall surface of the side wall 112 is d, where D > d, so that the flow area of the through hole 13 on the outer wall surface of the side wall 112 is larger than the flow area of the through hole 13 on the inner wall surface of the side wall 112. Of course, in other embodiments, the through hole 13 may also be in regular or irregular shapes such as oval, triangular, rectangular, etc. in the cross section parallel to the side wall 112, and the opening shape of the through hole 13 on the outer wall surface of the side wall 112 may be the same as or different from the opening shape of the through hole 13 on the inner wall surface of the side wall 112, as long as it is ensured that the flow area of the through hole 13 on the outer wall surface of the side wall 112 is larger than the flow area of the through hole 13 on the inner wall surface of the side wall 112, so that energy loss will occur when noise passes through the through hole 13. The embodiments of the present utility model do not make specific limitations here.

[0050] As Figure 3 shown, along the thickness direction of the side wall 112, the flow area of the through hole 13 gradually decreases from the outer wall surface of the side wall 112 towards the inner wall surface of the side wall 112. Noise can continuously generate energy loss when passing through the through hole 13, so as to improve the attenuation effect on the noise wave escaping towards the side wall 112, further reduce the outward escape of noise, and enhance the noise reduction and silencing effect of the silencing device 10. Moreover, the structure of the through hole 13 is simple, which is convenient for processing the through hole 13 on the side wall 112.

[0051] As Figure 3 shown, when the silencing device 10 is installed at the air outlet 31 of the cooking appliance, each through hole 13 has a central axis a, and there is an included angle α between the central axis a and the horizontal plane b, satisfying: 0° ≤ α ≤ 45°. Among them, the included angle α can be any angle within the range of 0° to 45°, such as 0°, 5°, 10°... 40°, 45°. The included angle α between the central axis a of the through hole 13 and the horizontal plane b is small, which can reduce the outward escape of the noise wave along the vertical direction through the through hole 13. It can be understood that the smaller the included angle α between the central axis a and the horizontal plane b, the less the noise wave along the vertical direction escapes through the through hole 13. Therefore, the included angle α is preferably 0°.

[0052] As Figure 3 shown, in one of the embodiments, a plurality of through holes 13 are arranged along the circumferential direction of the side wall 112 to attenuate as many noise waves along the horizontal direction as possible and improve the noise reduction effect. It is worth mentioning that the plurality of through holes 13 can be arranged at intervals along the circumferential direction of the side wall 112, or the plurality of through holes 13 can be evenly distributed along the circumferential direction of the side wall 112; or the plurality of through holes 13 are arranged in an array on the side wall 112.

[0053] As Figures 5 to 6As shown, the sound insulation device 10 further includes a water leakage hole 14, which is opened on the side wall 112 and close to the bottom wall 111. Herein, being close to the bottom wall 111 means that along the height direction of the side wall 112, the water leakage hole 14 is located in the area below the midline of the side wall 112. That is to say, at least part of the through holes 13 are higher than the water leakage hole 14. The condensed water generated in the cavity 113 can be discharged from the box body 11 through the water leakage hole 14, avoiding the condensed water blocking all the through holes 13 and affecting the normal exhaust of the cooking device through the through holes 13 and the air outlet holes 31. Moreover, the water leakage hole 14 is provided on the side wall 112 to avoid opening holes on the bottom wall 111, which may cause noise to escape outward through the openings on the bottom wall 111.

[0054] As Figure 6 shown, preferably, the bottom end of any through hole 13 is not lower than the top end of the water leakage hole 14. That is to say, along the height direction of the side wall 112, the distance h between the bottom end of the through hole 13 at the bottommost part of the side wall 112 and the top end of the water leakage hole 14 is h≥0. Thereby, it can be ensured that all the through holes 13 on the side wall 112 will not be blocked by condensed water, avoiding the influence of the condensed water blocking the through holes 13 on the noise reduction and sound insulation effect of the sound insulation device 10.

[0055] Among them, the number of the water leakage holes 14 can be one, two, three or more. The multiple water leakage holes 14 are arranged at intervals along the circumferential direction of the side wall 112, avoiding the condensed water or foreign objects blocking one of the water leakage holes 14 and resulting in the inability of the condensed water in the cavity 113 to be discharged normally.

[0056] In one embodiment, the box body 11 is a silica gel part. The silica gel part has the characteristics of a loose molecular structure and porosity, which can effectively isolate the propagation of noise waves, thereby improving the noise reduction and sound insulation effect of the sound insulation device 10. Moreover, the silica gel part has good thermal stability, is not easy to deform or damage in a high-temperature environment for a long time, has a long service life, and a low cost. Of course, in other embodiments, the box body 11 can also be made of other materials such as rubber and plastic, and the embodiments of the present utility model do not make specific limitations herein.

[0057] The sound insulation device 10 may also include a plurality of fixing members 12, which are arranged at intervals along the circumferential direction of the top end of the side wall 112 for fixedly connecting with the cover body 30, or the fixing members 12 are detachably connected to the cover body 30 for connecting the box body 11 at the air outlet hole 31. Refer to Figure 6 shown, in this embodiment, the sound insulation device 10 includes two.

[0058] Specifically, the fixing member 12 can be in the shape of a stepped structure to be able to cooperate with the assembly hole or the fixing position of the cover 30 for snap connection. It can also be in other shapes, or be fixed to the cover 30 through fasteners. The specific shape is not limited as long as it can be fixed to the cover 30. For example, the fixing member 12 can be set as fasteners such as screws and bolts to ensure the stability and reliability of the connection between the box body 11 and the cover 30, and it is also convenient for disassembling, assembling or replacing the sound insulation device 10. Moreover, the number of the fixing members 12 can be two, three or more. The multiple fixing members 12 are arranged at intervals along the circumferential direction of the side wall 112 to ensure the reliable connection between the box body 11 and the cover 30, and at the same time ensure that the end of the side wall 112 far from the bottom wall 111 fits against the inner wall surface of the cover 30. It is worth mentioning that the fixing member 12 can be integrally formed with the box body 11, which is beneficial to processing and reduces the fixing relationship between the fixing member 12 and the box body 11.

[0059] As Figures 1 to 2 shown, a cooking appliance provided by an embodiment of the present invention includes a pot body 20, a cover 30 and the above-mentioned sound insulation device 10, wherein: an air outlet hole 31 is provided on the top wall of the cover 30, and the cover 30 and the pot body 20 enclose a cooking cavity 40; the sound insulation device 10 is located in the cooking cavity 40, the top end of the side wall 112 fits against the inner wall surface of the cover 30, and the air outlet hole 31 corresponds to the open mouth of the box body 11. The gas generated in the cooking cavity 40 can also be discharged from the cooking appliance through the through hole 13, the cavity 113 and the air outlet hole 31. The fixing member 12 is used to fit the end of the side wall 112 far from the bottom wall 111 against the inner wall surface of the cover 30, so that the noise generated in the cooking cavity 40 can only escape outward through the through hole 13, the cavity 113 and the air outlet hole 31, and avoid the noise escaping through the gap between the side wall 112 and the inner wall surface of the cover 30 and affecting the noise reduction effect of the sound insulation device 10.

[0060] Among them, the cooking appliance can be an electric stew pot, an electric slow cooker, an electric steamer, etc., which heat the liquid in the cooking cavity 40 through a heating plate and heat the inner pot or food placed in the cooking cavity 40 through the liquid in the cooking cavity 40. The embodiment of the present invention does not make specific limitations here.

[0061] As Figures 4 to 5 shown, an extension part 1121 extends outward from the end of the side wall 112 far from the bottom wall 111. The fixing member 12 fixes the box body 11 to the inner wall surface of the cover 30 through the extension part 1121. The extension part 1121 is convenient for connecting with the fixing member 12 and can increase the contact area between the side wall 112 and the inner wall surface of the cover 30, further avoiding the noise escaping through the gap between the side wall 112 and the inner wall surface of the cover 30.

[0062] As Figure 2 and Figure 7As shown, the upper edge of the pot body 20 has a receiving portion 21. The lid body 30 is provided with a blocking portion 32 and a lapping portion 33. The lapping portion 33 and the blocking portion 32 form a step. The blocking portion 32 extends downward from the lower edge of the lid body 30, and the lapping portion 33 is lapped on the receiving portion 21. The lapping portion 33 is supported on the receiving portion 21 to increase the contact area between the upper edge of the pot body 20 and the lower edge of the lid body 30, and improve the sealing performance between the lid body 30 and the pot body 20. Due to manufacturing errors, there may be a gap between the lapping portion 33 and the receiving portion 21 and they may not fit perfectly. Since the blocking portion 32 extends downward from the lower edge of the lid body 30, it can block this gap, further improving the sealing performance between the lid body 30 and the pot body 20, thereby reducing the noise generated in the cooking cavity 40 from escaping through the gap between the lid body 30 and the pot body 20 and enhancing the user experience. Moreover, the step formed by the lapping portion 33 and the blocking portion 32 cooperates with the receiving portion 21 to limit the lid body 30, ensuring the stability and reliability when the lid body 30 is covered on the pot body 20.

[0063] As Figure 7 shown, in one embodiment, the receiving portion 21 has a supporting surface 212 and a mating surface 213. The lapping portion 33 is lapped on the supporting surface 212, and the blocking portion 32 and the mating surface 213 are at least partially overlapped. The blocking portion 32 and the mating surface 213 can isolate some noise waves that tend to escape towards the gap between the lid body 30 and the pot body 20. And the noise needs to turn at the lower edge of the blocking portion 32 and the upper edge of the mating surface 213 before it may escape through the gap between the supporting surface 212 and the lapping portion 33, causing energy loss when the noise passes through the blocking portion 32, the lapping portion 33 and the receiving portion 21, so as to further attenuate some noise waves that tend to escape towards the gap between the lid body 30 and the pot body 20, thereby reducing the noise generated in the cooking cavity 40 from escaping and enhancing the user experience.

[0064] As Figure 8 shown, in another embodiment, the receiving portion 21 is a groove 211, the blocking portion 32 is located in the groove 211, and the lapping portion 33 is lapped on the edge of the groove 211. The groove 211 can increase the contact area between the blocking portion 32 and the receiving portion 21, further improving the sealing performance between the lid body 30 and the pot body 20. The inner and outer walls of the groove 211 and the blocking portion 32 can isolate some noise waves that tend to escape towards the gap between the lid body 30 and the pot body 20. And the noise needs to turn multiple times between the groove 211 and the blocking portion 32 before it may escape through the gap between the edge of the groove 211 and the lapping portion 33, causing energy loss when the noise passes through the groove 211, the blocking portion 32 and the lapping portion 33, so as to further attenuate some noise waves that tend to escape towards the gap between the lid body 30 and the pot body 20, thereby reducing the noise generated in the cooking cavity 40 from escaping and enhancing the user experience.

[0065] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of concise description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope recorded in this specification.

[0066] The above-described embodiments only express several implementation manners of the present utility model. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several variations and improvements can still be made, and these all belong to the protection scope of the present utility model. Therefore, the protection scope of the present utility model patent shall be subject to the appended claims.
