Description

Technical Field

[0001] This utility model relates to the field of food processor technology, and specifically to a food processor. Background Technology

[0002] Food processors such as blenders, juicers, and soy milk makers typically include a blending cup, a body, and a lid. The blending cup rests on a base support of the body, which also includes a side support located beside the blending cup for connecting to the lid, allowing the lid to snap onto the top of the blending cup. A drawback of these food processors is the high noise level generated when the large blades inside the blending cup rotate. Utility Model Content

[0003] This utility model aims to at least partially solve one of the technical problems in the related art.

[0004] Therefore, embodiments of this utility model propose a low-noise food processor.

[0005] The food processor of this utility model includes a body and a food processor cup. The body includes a bottom support and a side support. The food processor cup is adapted to be placed on the bottom support. The side support is located on the side of the food processor cup and surrounds a portion of the outer peripheral surface of the food processor cup.

[0006] In this embodiment of the food processor, after the food processor cup is placed on the bottom support, the side support surrounds a portion of the outer circumference of the food processor cup. At this time, the sound propagation path emitted by part of the cup wall when the stirring blade inside the food processor cup is working is blocked by the side support, making its propagation path longer, its energy loss greater, and its operating noise lower.

[0007] In some embodiments, the outer surface of the side support includes a sound-absorbing surface surrounding a portion of the outer peripheral surface of the cooking cup, and a sound-absorbing gap extending circumferentially along the cooking cup is formed between the sound-absorbing surface and the cooking cup.

[0008] In this embodiment, the food processor, specifically the food processor cup and the side support, are spaced apart to prevent the vibration of the food processor cup from being transmitted to the side support and thus making the side support a noise source, resulting in better noise reduction.

[0009] In some embodiments, the width of the silencing gap varies circumferentially along the cooking cup.

[0010] In this embodiment of the food processor, the width of the silencing gap varies. When sound passes through the silencing gap, its propagation path after being reflected by the silencing surface and the outer surface of the food processor cup is more likely to overlap and become chaotic. This makes it easier for sound interference and cancellation to occur. Combined with the absorption of the vibration energy of the sound by the silencing surface and the outer surface of the food processor cup, the noise emitted by the food processor is lower.

[0011] In some embodiments, the width of the silencing gap gradually decreases or decreases in a stepped manner from the middle to both ends of the silencing gap along the circumference of the cooking cup.

[0012] In this embodiment, the food processor has a sound-absorbing gap that gradually decreases in width from the inside out or in a stepped manner. On the one hand, the smaller the width, the more sound reflections occur, the greater the air viscosity loss, and the more obvious the high-frequency cancellation. On the other hand, it also avoids forming a funnel shape, further preventing noise from gathering, and the food processor emits lower noise.

[0013] In some embodiments, along the circumference of the cooking cup, the width of the middle part of the silencing gap is A, and the width of the end of the silencing gap is B, wherein 1.5mm≤A≤6.8mm, and 1.1≤A / B≤1.72.

[0014] In this embodiment, the food processor is designed with 1.5mm≤A≤6.8mm and 1.1≤A / B≤1.72. This design avoids both excessively large maximum width of the noise reduction gap, which would reduce the compactness of the food processor's structure, and excessively small minimum width of the noise reduction gap, which would increase the likelihood of resonance between the food processor cup and the side support.

[0015] In some embodiments, the outer surface of the side support further includes two arc surfaces, which are respectively connected to the two ends of the silencing surface that are opposite to each other along the circumference of the cooking cup, and the two arc surfaces surround a portion of the outer circumferential surface of the cooking cup.

[0016] The food processor in this embodiment features a two-curved design, which allows the side support to encircle the food cup at opposite ends along its circumference. This design provides better sound cancellation and interference reduction at the curved surfaces, resulting in better noise reduction.

[0017] In some embodiments, along the circumference of the cooking cup, the width of the middle part of the silencing gap is A, the radius of curvature of the two arc surfaces is R, 1.5mm≤A≤6.8mm, 0.8A≤R≤3A.

[0018] In this embodiment, the food processor is configured with 1.5mm≤A≤6.8mm and 0.8A≤R≤3A. This makes it easier for the curved surface to reflect the sound back to the noise reduction gap when the sound travels from the noise reduction gap to the curved surface. As a result, the noise reduction effect is better and the interference and cancellation of sound is better.

[0019] In some embodiments, the sound-absorbing surface transitions smoothly with the curved surface.

[0020] In this embodiment, the food processor features a smooth transition between the sound-absorbing surface and the curved surface, which enhances the aesthetics of the side support and brings the edge of the curved surface away from the sound-absorbing surface closer to the food processor cup, resulting in better noise reduction.

[0021] In some embodiments, on a projection plane orthogonal to the central axis of the cooking cup, the angle formed by the line connecting the first end of the projection outline of the sound-absorbing surface to the center of the cooking cup and the line connecting the second end of the projection outline of the sound-absorbing surface to the center of the cooking cup is M, where M ≥ 90°.

[0022] In this embodiment, the food processor has a larger area surrounding the outer periphery of the food processor cup by setting M≥90°, resulting in better noise reduction.

[0023] In some embodiments, the thickness of the wall containing the sound-absorbing surface of the side support is C, wherein 2mm≤C≤5.5mm.

[0024] In this embodiment, the food processor, by setting 2mm≤C≤5.5mm, results in greater energy loss when sound penetrates the wall of the side support, better energy absorption by the side support, and lower noise from the food processor. Furthermore, it avoids the structural weakness and short lifespan caused by excessively thin side support walls.

[0025] In some embodiments, the body is generally L-shaped, the upper edge of the side support is higher than the upper edge of the cooking cup, and the height difference between the two is D, wherein D≥3mm.

[0026] In this embodiment, the food processor, by setting D≥3mm, absorbs more energy when the sound emitted by the side support propagates upwards from the food processor cup, resulting in lower noise. Attached Figure Description

[0036] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0037] The following describes the food processor 100 according to an embodiment of the present invention with reference to the accompanying drawings.

[0038] like Figures 1-7 As shown, the food processor 100 of this embodiment includes a body 1 and a food processor cup 2. The body 1 includes a bottom support portion 12 and a side support portion 11. The food processor cup 2 is adapted to be placed on the bottom support portion 12, and the side support portion 11 is located on the side of the food processor cup 2 and surrounds a portion of the outer peripheral surface of the food processor cup 2.

[0039] It is understandable that the side support 11 is provided with a relief groove. When the food processor 2 is placed on the bottom support 12, the spout of the food processor 2 is located in the relief groove, which makes the food processor 2 fit the side support 11 more closely, so that the food processor 100 has a compact structure and small size.

[0040] In this embodiment of the invention, after the food processor 100 is placed in the bottom support 12, the side support 11 surrounds a portion of the outer circumference of the food processor 2. At this time, the sound propagation path emitted by part of the cup wall of the food processor 2 when the stirring blade inside the food processor 2 is working is blocked by the side support 11, making its propagation path longer, its energy loss greater, and the food processor 100 operating noise lower.

[0041] In some embodiments, such as Figure 3 , Figure 4 and Figure 6 As shown, the outer surface of the side support 11 includes a sound-absorbing surface 111 that surrounds a portion of the outer peripheral surface of the cooking cup 2. A sound-absorbing gap 3 extending circumferentially from the sound-absorbing surface 111 and the cooking cup 2 is formed between them. That is, the cooking cup 2 is spaced apart from the side support 11, preventing the vibration of the cooking cup 2 from being transmitted to the side support 11 and thus preventing the side support 11 from becoming a noise source, resulting in better noise reduction.

[0042] For example, the cross-sectional profiles of the two sides of the side support 11 and the cooking cup 2 that are opposite each other are generally the same.

[0043] In some embodiments, the width of the silencing gap 3 varies along the circumference of the cooking cup 2.

[0044] That is, the width of the silencing gap 3 varies. When sound passes through the silencing gap 3, its propagation path after being reflected by the silencing surface 111 and the outer surface of the food processor 2 is more likely to be superimposed and confused. As a result, sound interference and cancellation are more likely to occur. Combined with the absorption of the vibration energy of sound by the outer surfaces of the silencing surface 111 and the food processor 2, the noise emitted by the food processor 100 is lower.

[0045] For example, the width of the noise reduction gap 3 can vary randomly along its extension direction. For instance, the noise reduction surface 111 can be set as a frosted surface with multiple protrusions, or the noise reduction surface 111 can be a wavy surface extending along its extension direction.

[0046] In some embodiments, along the circumference of the cooking cup 2, the width of the silencing gap 3 gradually decreases or decreases in a stepwise manner from the middle to both ends of the silencing gap 3.

[0047] By setting the width of the silencing gap 3 to gradually decrease from the inside out or in a stepped manner, on the one hand, the smaller the width, the more sound reflections, the greater the air viscosity loss, and the more obvious the high-frequency cancellation. On the other hand, it also avoids forming a funnel shape, further avoiding noise concentration, and the noise emitted by the food processor 100 is lower.

[0048] It should be noted that the width at the middle position of the silencing gap 3 refers to the average width of the middle section of the silencing gap 3, while the width at the end of the silencing gap 3 refers to the average width of its outlet section. For example... Figure 6 As shown, along the circumference of the cooking cup 2, the width of the silencing gap 3 gradually decreases from the middle to both ends of the silencing gap 3.

[0049] In some embodiments, such as Figure 6 As shown, along the circumference of the cooking cup 2, the width of the middle part of the silencing gap 3 is A, and the width of the end of the silencing gap 3 is B, where 1.5mm≤A≤6.8mm, 1.1≤A / B≤1.72.

[0050] By setting 1.5mm≤A≤6.8mm and 1.1≤A / B≤1.72, on the one hand, the maximum width of the noise reduction gap 3 is not too large, which would reduce the structural compactness of the food processor 100; on the other hand, the minimum width of the noise reduction gap 3 is not too small, which would increase the probability of resonance when the food processor cup 2 comes into contact with the side support 11.

[0051] For example, the width A of the middle part of the silencing gap 3 can be 1.5mm, 3.5mm or 6.8mm, and the ratio of the width A of the middle part of the silencing gap 3 to the width B of the end part can be 1.1, 1.4 or 1.72A.

[0052] In some embodiments, such as Figure 4 and Figure 6As shown, the outer surface of the side support 11 also includes two arc surfaces 112. The two arc surfaces 112 are respectively connected to the two ends of the sound-absorbing surface 111 that are opposite to each other along the circumference of the cooking cup 2. The two arc surfaces 112 surround a part of the outer circumferential surface of the cooking cup 2.

[0053] The design of the two curved surfaces 112 makes the side support 11 form a hug around the 2 at the two opposite ends of the circumference of the cooking cup 2. The curved surfaces 112 have a better effect on canceling out and interfering with sound, resulting in better noise reduction.

[0054] For example, both arc surfaces 112 extend along the height direction of the side support 11, and the two arc surfaces 112 are arranged in a mirror symmetrical manner.

[0055] Optionally, along the circumference of the cooking cup 2, the width of the middle part of the silencing gap 3 is A, and the radius of curvature of the two arc surfaces 112 is R, where 1.5mm≤A≤6.8mm and 0.8A≤R≤3A.

[0056] By setting 1.5mm≤A≤6.8mm and 0.8A≤R≤3A, when sound propagates from the silencer gap 3 to the arc surface 112, the arc surface 112 more easily reflects the sound back to the silencer gap 3, thus achieving better interference and cancellation effects on the sound and better noise reduction.

[0057] For example, the ratio of the radius of curvature R of the arc surface 112 to the width A of the middle part of the silencing gap 3 can be 0.8, 1.1, 1.5, 2 or 3.

[0058] In some embodiments, such as Figure 4 As shown, the sound-absorbing surface 111 and the curved surface 112 transition smoothly.

[0059] The smooth transition between the sound-absorbing surface 111 and the curved surface 112 makes the side support part 11 more aesthetically pleasing at this point, and also makes the edge of the curved surface 112 away from the sound-absorbing surface 111 closer to the cooking cup 2, resulting in better noise reduction.

[0060] For example, the silencing surface 111 is in contact with the arc surface 112 at the junction with the arc surface 112. The width of the gap formed between the outer peripheral surface of the cooking cup 2 and the arc surface 112 can gradually increase or gradually decrease in the direction away from the silencing gap 3.

[0061] In some embodiments, such as Figure 5 As shown, on the projection plane orthogonal to the central axis of the cooking cup 2, the angle formed by the line connecting the first end of the projection outline of the sound-absorbing surface 111 to the center of the cooking cup 2 and the line connecting the second end of the projection outline of the sound-absorbing surface 111 to the center of the cooking cup 2 is M, where M ≥ 90°.

[0062] By setting M≥90°, the area of ​​the sound-absorbing surface 111 surrounding the outer periphery of the cooking cup 2 is larger, resulting in better noise reduction.

[0063] For example, M can be 90°, 95°, 115°, or 120°. The larger the angle, the greater the ratio of the area enclosed by the outer circumference of the cooking cup 2 to the outer circumference of the cooking cup 2, and the better the sound is muffled by the side support 11.

[0064] In some embodiments, such as Figure 6 As shown, the thickness of the wall where the sound-absorbing surface 111 of the side support 11 is located is C, where 2mm≤C≤5.5mm.

[0065] By setting C to 2mm ≤ C ≤ 5.5mm, the energy loss when sound penetrates the wall of the side support 11 is greater, the side support 11 absorbs sound energy better, and the noise emitted by the food processor 100 is lower. Furthermore, it avoids the structural strength and lifespan caused by an excessively thin wall of the side support 11.

[0066] For example, the thickness C of the wall where the sound-absorbing surface 111 of the side support 11 is located can be 2 mm, 2.8 mm or 5.5 mm.

[0067] In some embodiments, such as Figure 7 As shown, the body 1 is roughly L-shaped, with the upper edge of the side support 11 higher than the upper edge of the blending cup 2, and the height difference between the two is D, where D≥3mm. By setting D≥3mm, the side support 11 absorbs more energy when the sound emitted from the blending cup 2 propagates upwards, resulting in lower noise.

[0068] For example, the height difference D between the upper surface of the side support 11 and the upper edge of the food processor 2 can be 3mm, 5mm or 7mm. The food processor 100 also includes a lid, with one part inserted into the food processor 2 and the other part covering the top of the food processor 2 to fill the height difference.
