Description

Technical Field

[0001] This utility model relates to the field of household appliances, and in particular to a heating base and an electric slow cooker. Background Technology

[0002] An electric slow cooker includes a base, a pot body, and an inner pot. The inner pot is located inside the pot body, and the pot body is equipped with a heating plate for heating the liquid inside the pot body. In turn, the liquid heats the food inside the inner pot, thus heating the food inside the inner pot.

[0003] When the electric slow cooker is working, the temperature difference of the heating surface of the heating plate is large. Localized overcooling and boiling will produce a large number of bubbles and noise. The noise generated by the heating plate will be transmitted downwards and dissipated outwards through the base. When the noise is loud, it will affect the user experience. Utility Model Content

[0004] In view of this, it is necessary to provide a heating base and an electric slow cooker to address the above problems, so as to reduce the noise generated by the electric heating plate from escaping outward through the base.

[0005] This utility model first provides a heating base, including: a bottom shell; an inner shell disposed on the bottom shell, the inner shell having a heating cavity; and a heating element disposed on the bottom wall of the inner shell; wherein, there is a receiving cavity between the bottom shell and the inner shell, and a noise-reducing baffle is disposed in the receiving cavity, the noise-reducing baffle being located below the heating element.

[0006] In the aforementioned heating base, the heating chamber inside the inner shell is used to hold liquid. The inner pot of the electric slow cooker is located inside the heating chamber. The heating element can heat the liquid inside the chamber, thereby heating the food in the inner pot. When the heating base is working, the noise generated by the heating element will dissipate downwards. Some of the noise will be blocked and attenuated by the noise reduction baffles, thus playing a role in noise reduction and sound attenuation. This reduces the noise generated by the heating element during operation from dissipating outwards through the bottom shell, improving the user experience.

[0007] In one embodiment, the noise-reducing baffle is disposed on the bottom shell, and the noise-reducing baffle extends generally in a direction parallel to the heating element.

[0008] This design ensures that the noise reduction surface of the noise reduction baffle is perpendicular to the direction of most noise propagation, thereby improving the noise reduction baffle's attenuation effect on the noise generated by the heating element.

[0009] In one embodiment, the bottom wall of the bottom shell is provided with heat dissipation holes, and the inner wall of the heat dissipation holes is provided with the noise reduction baffle.

[0010] This design allows the noise-reducing baffle to block some of the noise that escapes through the heat dissipation holes, thus reducing noise; at the same time, the noise-reducing baffle also increases the strength of the heat dissipation holes.

[0011] In one embodiment, the heat dissipation hole has opposing first inner sidewalls and second inner sidewalls; the noise reduction baffle includes a first baffle and a second baffle, the first baffle extending from the first inner sidewall toward the second inner sidewall, and the second baffle extending from the second inner sidewall toward the first inner sidewall.

[0012] With this configuration, the first and second baffles can improve the attenuation effect of the noise reduction baffles on noise waves propagating in the vertical direction; and, some noise will be redirected after being blocked by the first or second baffles, and the first and second inner sidewalls can also attenuate some noise waves propagating in the horizontal direction, thereby improving the noise reduction effect.

[0013] In one embodiment, the projection of the first baffle on the horizontal plane coincides with the projection of the second baffle on the horizontal plane.

[0014] This design reduces the likelihood of noise waves propagating vertically escaping directly without being attenuated by the first or second baffle, thus improving noise reduction. Furthermore, the first and second baffles also prevent foreign objects from entering the cavity through the heat dissipation holes.

[0015] In one embodiment, the first baffle is located above the second baffle, and the top of the second inner sidewall is higher than the top surface of the first baffle.

[0016] With this configuration, noise waves propagating in the horizontal direction will be preferentially blocked and attenuated by the portion of the second inner wall that is higher than the top surface of the first baffle, thereby improving the noise reduction effect.

[0017] In one embodiment, the vertical distance H between the top of the second inner sidewall and the top surface of the first baffle satisfies: H≥2mm.

[0018] This configuration can improve the blocking and attenuation effect of the portion of the second inner sidewall that is higher than the top surface of the first baffle on noise propagating towards the outward periphery.

[0019] In one embodiment, the heat dissipation holes are arranged in groups, and each group of heat dissipation holes is formed by a plurality of heat dissipation holes spaced apart circumferentially along the bottom shell. The heating element includes a heating tube, and the projection of the heating tube on the horizontal plane is located within the projection of the line connecting the outer edges of the first baffle of the innermost group of heat dissipation holes on the horizontal plane.

[0020] This design ensures that the heat and noise generated during the operation of the heating base can be evenly dissipated through multiple heat dissipation holes, preventing heat concentration from affecting the normal use of the heating base and also preventing noise concentration from increasing and affecting the user experience. Furthermore, it prevents the noise waves generated when the heating tube undergoes localized supercooling and boiling, producing a large number of bubbles, from directly entering the heat dissipation holes, thereby significantly attenuating the noise that dissipates vertically downwards from the bubble generation area and improving the noise reduction effect.

[0021] In one embodiment, the bottom wall of the bottom shell is provided with a through hole, and the bottom wall of the bottom shell is also provided with a third baffle extending upward from the edge of the through hole, the third baffle and the inner wall of the through hole forming the heat dissipation hole.

[0022] This design ensures sufficient space for processing noise-reducing baffles while also preventing the bottom wall of the base from becoming too thick, which would increase the overall weight of the heating base.

[0023] This utility model also provides an electric slow cooker, including an inner pot and a heating base as described above, wherein the inner pot is disposed inside the heating chamber. Attached Figure Description

[0033] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "or / and" as used herein includes any and all combinations of one or more of the associated listed items.

[0034] An electric slow cooker consists of a base, a pot body, and an inner pot. The inner pot is located inside the pot body, which has a heating plate to heat the liquid inside. This liquid then heats the food inside the inner pot. When the slow cooker is working, the heating surface of the heating plate experiences a large temperature difference, which can cause localized subcooling and boiling, generating numerous bubbles and noise. This noise is transmitted downwards and dissipates outwards through the base. Excessive noise can negatively impact the user experience.

[0035] To solve the above problems, such as Figures 1 to 6 As shown, this application provides a heating base and an electric slow cooker to reduce the noise generated by the electric heating plate from dissipating outward through the base.

[0036] like Figures 1 to 2 As shown, specifically, the heating base 100 includes a bottom shell 10, an inner shell 20, and a heating element 30. The inner shell 20 is disposed on the bottom shell 10 and has a heating cavity 21. The heating element 30 is disposed on the bottom wall of the inner shell 20. There is a receiving cavity 40 between the bottom shell 10 and the inner shell 20. A noise reduction baffle 12 is disposed in the receiving cavity 40 and is located below the heating element 30.

[0037] In the aforementioned heating base 100, the heating chamber 21 of the inner shell 20 is used to hold liquid. The inner pot 200 of the electric slow cooker is located inside the heating chamber 21. The heating element 30 can heat the liquid in the heating chamber 21, thereby heating the food in the inner pot 200 through the liquid. When the heating base 100 is working, due to the large temperature difference of the heating surface of the heating element 30, local supercooling and boiling will occur, generating a large number of bubbles and noise. The noise generated by the heating element 30 will dissipate downwards, and some of the noise will be blocked and attenuated by the noise reduction baffle 12, thereby playing a role in noise reduction and sound attenuation, reducing the noise generated by the heating element 30 during operation from dissipating outwards through the bottom shell 10, and improving the user experience.

[0038] like Figure 1 and Figure 3 As shown, in one embodiment, the noise-reducing baffle 12 is disposed on the bottom shell 10, and the noise-reducing baffle 12 extends approximately in a direction parallel to the heating element 30. That is, the noise-reducing surface of the noise-reducing baffle 12 faces the heating element 30 and is parallel to the heating surface of the heating element 30. Here, the influence of processing and assembly errors is ignored. Since most of the noise generated by the heating element 30 during operation propagates in a direction perpendicular to the heating element 30, the noise-reducing surface of the noise-reducing baffle 12 is perpendicular to the propagation direction of most noise, thereby improving the noise attenuation effect of the noise-reducing baffle 12 on the noise generated by the heating element 30 during operation.

[0039] In another embodiment, the noise-reducing baffle 12 may extend in a direction perpendicular to the heating element 30, or the extension direction of the noise-reducing baffle 12 may be inclined to the heating element 30, that is, the noise-reducing surface of the noise-reducing baffle 12 is perpendicular to the heating surface of the heating element 30 or forms an angle with the heating surface of the heating element 30. In this case, the noise-reducing baffle 12 can also block some of the noise transmitted downward through the side wall of the inner shell 20 after the bubbles at the gas-liquid interface burst. Of course, in other embodiments, the noise-reducing baffle 12 may also be provided in the inner shell 20 and extend downward toward the heating element 30.

[0040] like Figures 1 to 2 As shown, the bottom wall of the bottom shell 10 is provided with heat dissipation holes 11, and the inner wall of the heat dissipation holes 11 is provided with noise reduction ribs 12. Heat inside the bottom shell 10 can be dissipated through the heat dissipation holes 11. Since some of the noise generated by the heating element 30 will dissipate outward through the heat dissipation holes 11, the noise reduction ribs 12 are provided on the inner wall of the heat dissipation holes 11 to block some of the noise dissipating through the heat dissipation holes 11, thus achieving noise reduction and sound attenuation. At the same time, the noise reduction ribs 12 also increase the strength at the heat dissipation holes 11.

[0041] like Figure 2 and Figure 4As shown, in one embodiment, the bottom wall of the base shell 10 is provided with a through hole 13, and the bottom wall of the base shell 10 is also provided with a third baffle 14 extending upward from the edge of the through hole 13. The third baffle 14 and the inner wall of the through hole 13 form a heat dissipation hole 11. In this way, the bottom wall of the base shell 10 is not made too thick, thus avoiding an increase in the overall weight of the heating base 100. Of course, in other embodiments, the through hole 13 can also be opened on the bottom wall of the base shell 10, and the through hole 13 can directly serve as the heat dissipation hole 11.

[0042] like Figure 2 As shown, the heat dissipation hole 11 has a first inner sidewall 111 and a second inner sidewall 112 opposite to each other; the noise reduction baffle 12 includes a first baffle 121 and a second baffle 122, the first baffle 121 extends from the first inner sidewall 111 toward the second inner sidewall 112, and the second baffle 122 extends from the second inner sidewall 112 toward the first inner sidewall 111. Both the first baffle 121 and the second baffle 122 can attenuate some of the noise waves propagating in the vertical direction. Since most of the noise emitted towards the bottom wall of the base shell 10 when the heating base 100 is working propagates in the vertical direction, the first baffle 121 and the second baffle 122, which protrude from the first inner sidewall 111 and the second inner sidewall 112 respectively, can improve the attenuation effect of the noise-reducing baffle 12 on the noise waves propagating in the vertical direction. Furthermore, some noise will be redirected after being blocked by the first baffle 121 or the second baffle 122, and the first inner sidewall 111 and the second inner sidewall 112 can also attenuate some of the noise waves propagating in the horizontal direction, thereby improving the noise reduction effect. It should be noted that the noise wave in the vertical direction refers to the noise wave that propagates approximately in the vertical direction, and its propagation direction can be completely vertical or at a small angle to the vertical direction; the noise wave in the horizontal direction refers to the noise wave that propagates approximately in the horizontal direction, and its propagation direction can be completely horizontal or at a small angle to the horizontal direction.

[0043] like Figure 2 As shown, in one embodiment, the first baffle 121 is perpendicular to the first inner sidewall 111, and the second baffle 122 is perpendicular to the second inner sidewall 112, so as to ensure the attenuation effect of the first baffle 121 and the second baffle 122 on noise waves propagating in the vertical direction. Of course, in other embodiments, the first baffle 121 may also form an angle with the first inner sidewall 111, and the second baffle 122 may also form an angle with the second inner sidewall 112, as long as the first baffle 121 and the second baffle 122 can both attenuate part of the noise waves propagating in the vertical direction. This embodiment of the present invention does not impose specific limitations here.

[0044] like Figure 2As shown, in one embodiment, there is one first baffle 121 and one second baffle 122, with the first baffle 121 located above the second baffle 122. Noise waves propagating vertically are first blocked by the first baffle 121, and some of the noise waves will deflect and propagate horizontally. Noise waves propagating horizontally are then blocked by the second inner wall 112, and some of the noise waves deflect and propagate vertically again. Noise waves propagating vertically are blocked by the second baffle 122, and some of the noise waves deflect and propagate horizontally again. Noise waves propagating horizontally are then blocked by the first inner wall 111, and some of the noise waves deflect and dissipate vertically again outside the bottom shell 10. Figure 2 P represents the propagation path of the noise.

[0045] In another embodiment, there is one first baffle 121 and one second baffle 122, with the second baffle 122 located above the first baffle 121. Noise waves propagating vertically are first blocked by the second baffle 122, and some of the noise waves are redirected and propagated horizontally. Noise waves propagating horizontally are then blocked by the first inner wall 111, and some of the noise waves are redirected and propagated vertically again. Noise waves propagating vertically are blocked by the first baffle 121, and some of the noise waves are redirected and propagated horizontally again. Noise waves propagating horizontally are then blocked by the second inner wall 112, and some of the noise waves are redirected and dispersed vertically out of the bottom shell 10. Of course, in other embodiments, there can be two, three, or more first baffles 121 and second baffles 122, and preferably, the first baffles 121 and second baffles 122 are arranged alternately in the vertical direction.

[0046] like Figure 2As shown, the first baffle 121 is located above the second baffle 122, and the top of the second inner sidewall 112 is higher than the top surface of the first baffle 121. Noise waves propagating in the horizontal direction will be preferentially blocked and attenuated by the portion of the second inner sidewall 112 that is higher than the top surface of the first baffle 121, thereby improving the noise reduction effect. In the illustrated embodiment, the first inner sidewall 111 is closer to the center of the bottom shell 10 than the second inner sidewall 112, that is, the first inner sidewall 111 is away from the center of the bottom shell 10, and the second inner sidewall 112 is towards the center of the bottom shell 10. Since the heating element 30 is usually located at the center of the inner shell 20, most of the noise generated when the heating base 100 is working propagates from the center of the heating element 30 towards the outer periphery. At this time, the noise waves propagating towards the outer periphery will be preferentially blocked and attenuated by the portion of the second inner sidewall 112 that is higher than the top surface of the first baffle 121. Furthermore, since some of the noise waves blocked by the second baffle 122 will turn towards the center of the bottom shell 10 and propagate horizontally, the noise that dissipates outside the bottom shell 10 can also propagate towards the center of the bottom shell 10. The first inner sidewall 111 and the second inner sidewall 112 can further reduce the noise dissipation to the outside of the heating base 100. Of course, in other embodiments, the second inner sidewall 112 may be closer to the center of the bottom shell 10 than the first inner sidewall 111, that is, the second inner sidewall 112 may be away from the center of the bottom shell 10, and the first inner sidewall 111 may be towards the center of the bottom shell 10.

[0047] Preferably, the vertical distance H between the top of the second inner sidewall 112 and the top surface of the first baffle 121 satisfies: H ≥ 2 mm. H can be any value greater than or equal to 2 mm, such as 2 mm, 2.1 mm, 2.2 mm, 2.3 mm, 2.4 mm, 2.5 mm, 3 mm, 4 mm, or 5 mm. This improves the blocking and attenuation effect of the portion of the second inner sidewall 112 above the top surface of the first baffle 121 on noise propagating towards the outward periphery.

[0048] like Figure 2 , Figure 4 and Figure 6As shown, the projection of the first baffle 121 onto the horizontal plane coincides with the projection of the second baffle 122 onto the horizontal plane. That is, when looking down at the heating base 100, the desktop or other external structures at the bottom of the heating base 100 cannot be directly seen through the heat dissipation holes 11. This reduces the likelihood of vertically propagating noise waves escaping directly without being attenuated by the first baffle 121 or the second baffle 122, further improving noise reduction. Furthermore, the first baffle 121 and the second baffle 122 also prevent external dust and other foreign objects from entering the receiving cavity 40 through the heat dissipation holes 11. It should be noted that the coincidence of the projection of the edge of the first baffle 121 away from the first inner wall 111 onto the horizontal plane and the projection of the edge of the second baffle 122 away from the second inner wall 112 onto the horizontal plane also falls under the category of partial overlap of the projections of the first baffle 121 and the second baffle 122 onto the horizontal plane.

[0049] like Figure 3 and Figure 5 As shown, the heat dissipation holes 11 are arranged in groups, with each group consisting of multiple heat dissipation holes 11 spaced apart circumferentially along the bottom shell 10. Since the heating element 30 is typically located at the center of the inner shell 20, the multiple heat dissipation holes 11 spaced apart circumferentially along the bottom shell 10 ensure that the heat and noise generated by the heating base 100 during operation are dissipated evenly through the multiple heat dissipation holes 11, preventing heat concentration from affecting the normal operation of the heating base 100, and also preventing noise concentration from increasing and affecting the user experience. Each group of heat dissipation holes 11 may include two, three, four, or more holes. Furthermore, the bottom wall of the bottom shell 10 may have one, two, three, four, or more groups of heat dissipation holes 11. When there are two or more groups of heat dissipation holes 11, each group of holes 11 is arranged radially spaced along the bottom shell 10.

[0050] like Figure 3 and Figure 5 As shown, in one embodiment, the heat dissipation hole 11 is an arc-shaped hole or a strip-shaped hole. Arc-shaped and strip-shaped holes have simple structures, are easy to manufacture, and can ensure the heat dissipation effect of the heating base 100. Specifically, when the heating element 30 is circular and the heat dissipation hole 11 is an arc-shaped hole, the projection of the center of the arc-shaped hole onto the horizontal plane is preferably coincident with the projection of the center of the heating element 30 onto the horizontal plane. Of course, in other embodiments, the heat dissipation hole 11 can also be a circular hole, a square hole, or other regular or irregular shapes; this embodiment of the present invention does not impose specific limitations here.

[0051] like Figure 4As shown, when the third baffle 14 and the inner wall of the through hole 13 form a heat dissipation hole 11, the bottom wall of the bottom shell 10 is also provided with a fourth baffle 15 extending upward from both ends of the arc-shaped hole or the strip-shaped hole. The fourth baffle 15 is connected to both the first baffle 121 and the third baffle 14. The fourth baffle 15 can block noise escaping towards both ends of the arc-shaped hole or the strip-shaped hole.

[0052] like Figure 1 As shown, the heating element 30 includes a heating tube 31 and a heating plate 32. The heating tube 31 is located at the bottom of the heating plate 32 and heats the liquid in the heating chamber 21 through the heating plate 32. The projection of the heating tube 31 on the horizontal plane is located within the projection of the line connecting the outer edges of the first baffle 121 of the innermost set of heat dissipation holes 11 on the horizontal plane. Specifically, when the heating tube 31 is annular, the heat dissipation holes 11 are arc-shaped holes, and the projection of the center of the arc-shaped hole on the horizontal plane coincides with the projection of the center of the heating tube 31 on the horizontal plane, the diameter D2 of the line connecting the outer edges of the first baffle 121 of the innermost set of heat dissipation holes 11 is greater than the outer diameter D1 of the heating tube 31. In this way, the noise waves generated when the heating tube 31 undergoes localized supercooling and boiling to produce a large number of bubbles, which propagate vertically, will not directly enter the heat dissipation hole 11. Instead, they need to be attenuated by the first baffle 121, the second inner wall 112, the second baffle 122, and the first inner wall 111 in sequence before dissipating. This can significantly reduce the noise that dissipates vertically downward from the bubble generation area and improve the noise reduction effect.

[0053] like Figure 1 As shown, this embodiment of the present invention also provides an electric slow cooker, including an inner pot 200 and the aforementioned heating base 100, with the inner pot 200 disposed within the heating chamber 21. The heating element 30 can heat the liquid within the heating chamber 21, thereby heating the food in the inner pot 200 through the liquid, thus achieving the heating of the food in the inner pot 200. The electric slow cooker can be an electric stew pot or similar appliance that uses the heating element 30 to heat the liquid within the heating chamber 21, and the liquid within the heating chamber 21 to heat the inner pot 200; this embodiment of the present invention does not impose specific limitations here.

[0054] The technical features of the above embodiments can be combined in any way. For the sake of brevity, 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, they should be considered to be within the scope of this specification.

[0055] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
