Description

Technical Field

[0001] The invention relates to the field of household food processing equipment, and in particular to a low-noise food processing machine. Background Art

[0002] Existing household food processors (such as wall breaking machines, soy milk machines, and food processors) use motors to drive the agitator to rotate at high speed to achieve food mixing and crushing effects. In order to ensure better mixing and crushing effects, high-speed motors are often used to run at high speeds. Although this can improve food processing efficiency, it will also generate excessive working noise due to the high-speed rotation of the motor and the collision of ingredients in the food cup with the agitator.

[0003] In the prior art, noise reduction of food processing machines is generally achieved by adding a motor cover to the motor and adding noise-reducing materials. However, these noise reduction methods are costly to implement and have poor noise reduction effects, making it difficult to achieve low-cost and significant noise reduction.

[0004] There are also technical solutions in the prior art that add a closed outer cover to reduce noise. For example, Chinese patent application CNCN2020214162322 discloses a low-noise wall-breaking food processor, including a main body, a cup body and a cup cover installed on the upper part of the main body, and a first cover body and a second cover body that are arranged in a left-right rotating opening and closing manner through a connecting shaft, and the main body and the cup body are arranged in the cavity of the first cover body and the second cover body. The technical solution is to place the main body and the cup body in the cavity of the first cover body and the second cover body, which can effectively reduce the noise generated by the mixing blade and the food cutting directly transmitted to the outside world, and can also effectively reduce the noise generated by the high-speed rotating drive motor of the main body directly transmitted to the outside world. However, the means of adding an outer cover body will not only increase the realization cost of the product, resulting in a more complicated structure of the product, but also cause the user to frequently rotate the cover body during use, which is inconvenient for the user to operate and use.

DETAILED DESCRIPTION

[0031] In order to further explain the technical means and effects adopted by the present application to achieve the predetermined purpose, the specific implementation methods, structures, features and effects of the present application are described in detail below in conjunction with the accompanying drawings and preferred embodiments. In the following description, different "one embodiment" or "embodiment" does not necessarily refer to the same embodiment. In addition, specific features, structures, or characteristics in one or more embodiments may be combined in any suitable form.

[0032] like Figure 1-Figure 7 As shown, the present invention discloses a low-noise food processor, including a main machine 1 and a processing component 2 for processing food; the main machine 1 includes a main housing 11 enclosing a receiving cavity 111 and a support base 12 located at the bottom of the receiving cavity 111, and the vertical side surface of the receiving cavity 111 is provided with an assembly opening, and the assembly opening provides the processing component 2 to be inserted into the receiving cavity 111 or separated and removed from the receiving cavity 111; when the processing component 2 is inserted into the receiving cavity 111 from the assembly opening, the support base 12 provides support for the processing component 2, and the main housing 11 is arranged around the outer side surface of the processing component 2.

[0033] Compared with the prior art, the food processing machine disclosed in the present invention eliminates the need for a separate cover body to be provided on the outer side of the processing component 2. Instead, the main housing 11 of the main machine 1 is arranged into an enclosure structure to form the accommodating cavity 111 with an assembly opening on the vertical side. The processing component 2 is provided with an insertion operation into the accommodating cavity 111 or a removal operation from the accommodating cavity 111 through the assembly opening, so that the processing component 2 and the main machine 1 form a separable left-right enclosure structure, and the following technical effects are obtained accordingly: first, when the main housing 11 is arranged on the outer side of the processing component 2, the noise generated by the operation of the processing component 2 is shielded and isolated, thereby obtaining a better sound insulation and noise reduction effect with a simple structure, and the user operation and use are very simple; second, due to the left-right enclosure structure of the food processing machine, compared with similar products with the existing upper and lower structures, the overall structure is more compact and the external dimensions are smaller, so that it is convenient for users to store and use.

[0034] In order to further facilitate the user to insert the processing component 2 into the accommodating cavity 111 or remove it from the accommodating cavity 111 through the assembly opening, in a preferred embodiment, a guide device is provided on the support base 12, and the guide device provides guidance for the processing component 2 during the process of inserting it into the accommodating cavity 111 or removing it from the accommodating cavity 111.

[0035] For example, the guiding device is a sliding structure or a rotating structure arranged between the supporting base 12 and the main housing 11, so that the supporting base 12 is slidably arranged or rotated relative to the accommodating cavity 111 from the assembly opening.

[0036] The sliding structure is usually a matching structure of a slide rail and a slide groove. For example, a slide groove is provided on the inner wall of the accommodating cavity 111, and a slide rail located in the slide groove is correspondingly provided on the periphery of the support base 12, so that the support base 12 can slide in the slide groove using the slide rail, so that it can slide from the assembly opening into the accommodating cavity 111, or partially slide out of the accommodating cavity 111 through the assembly opening. The processing component 2 is placed on the support base 12, and then the support base 12 is pushed into the accommodating cavity 111 according to the sliding structure, so that the processing component 2 can be inserted into the accommodating cavity 111, so that the processing component 2 can be assembled to the host 1.

[0037] The rotating structure can be specifically implemented in various ways such as a rotating shaft and a hinge. Taking the hinge as an example, the support base 12 is hinged to the lower end of the main housing 11, so that the support base 12 can be rotated from the assembly opening into the accommodating cavity 111, or rotated out from the accommodating cavity 111 through the assembly opening. When in use, the processing component 2 is placed on the support base 12, and the support base 12 is rotated from the assembly opening into the accommodating cavity 111, so that the processing component 2 can be inserted into the accommodating cavity 111 to realize the assembly of the processing component 2 to the main unit 1; when the processing component 2 needs to be separated from the main unit 1, the support base 12 is rotated out from the accommodating cavity 111 through the assembly opening, and then the processing component 2 is removed from the support base 12, which is simple to operate and easy to use.

[0038] In one embodiment, the guide device includes a rotation-stopping groove 121 provided on the support base 12 and a support table 122 located around the rotation-stopping groove 121 to support the processing assembly 2. The rotation-stopping groove 121 provides a sliding guide for the bottom of the processing assembly 2, so that the bottom of the processing assembly 2 can be inserted into the accommodating cavity 111 along the rotation-stopping groove 121, or can be moved in the opposite direction along the rotation-stopping groove 121 to be separated from the accommodating cavity 111, so that the user can conveniently insert, assemble and separate the processing assembly 2 relative to the host 1.

[0039] Preferably, a guide opening is provided at the end of the stop groove 121 near the assembly opening, which further facilitates the bottom of the processing component 2 to be inserted into the stop groove 121 along the guide opening, and then allows the processing component 2 to be inserted into the accommodating cavity 111 to realize the assembly of the processing component 2 onto the main machine 1.

[0040] The first end of the support base 12 extends from the assembly opening to the accommodating cavity 111, and the guide opening is provided at the first end of the support base 12. This structure facilitates the use of the bottom of the processing assembly 2 and the first end of the support base 12 extending from the accommodating cavity 111 for guiding cooperation before inserting the processing assembly 2 from the assembly opening to the accommodating cavity 111, so as to facilitate operation by the user.

[0041] A plurality of foot pads 124 are provided at the bottom of the support base 12 , and the main machine 1 can be placed stably by using the foot pads 124 , ensuring that the food processor remains stable during use and is not prone to shaking and generating noise.

[0042] Specifically, a circuit board 16 is provided in the main housing 11 of the main machine 1, and a first coupler 15 electrically connected to the circuit board 16 is provided on the main housing 11, and the first coupler 15 is located in the accommodating cavity 111; the processing assembly 2 includes a cup holder 21 with a motor 214, a cup body 22 fixed on the cup holder 21, a processor 23 (for example, the processor 23 is a blender or a chopper) located in the cup body 22 and driven by the motor 214, and a cup cover 24 that can cover the cup body 22; a second coupler 211 electrically connected to the motor 214 is provided on the cup holder 21. When the processing assembly 2 is inserted into the accommodating cavity 111, the first coupler 15 is electrically connected to the second coupler 211, and the circuit board 16 cooperates with the first coupler 15 and the second coupler 211 to supply power to the motor 214 and control the operation of the motor 214. When the processor 23 driven by the motor 214 is powered on, it rotates in the cup body 22 to stir and break the food in the cup body 22 .

[0043] The host 1 further includes a limiting top plate 18 disposed at the top of the accommodating cavity 111 , and an operation panel 19 electrically connected to the circuit board 16 is disposed on the limiting top plate 18 , so that a user can operate the food processor through the operation panel 19 .

[0044] In this embodiment, the bottom side of the cup holder 21 is provided with a downwardly convex positioning boss 215 and a placement platform 216 located on the side of the positioning boss 215. When inserting the processing component 2 into the accommodating cavity 111, the positioning boss 215 is inserted from the guide opening of the anti-rotation groove 121, so that the processing component 2 cooperates with the anti-rotation groove 121 with the positioning boss 215, and the placement platform 216 is supported by the support platform 122, and the processing component 2 is pushed toward the accommodating cavity 111 until the second coupler 211 of the processing component 2 is coupled and connected with the first coupler 15 of the host 1, and the processing component 2 is inserted and assembled into the accommodating cavity 111, so that the operation is simple and convenient to use.

[0045] A first guide bevel 123 is provided between the support platform 122 and the anti-rotation groove 121, and the two opposite side surfaces of the positioning boss 215 have a second guide bevel formed by shrinking from top to bottom. When the positioning boss 215 is inserted from the guide opening of the anti-rotation groove 121, the second guide bevel and the first guide bevel 123 form an inclined surface matching connection, which is beneficial to reduce the matching resistance between the positioning boss 215 and the anti-rotation groove 121, so that the processing component 2 can be better assembled into the accommodating cavity 111 or separated from the accommodating cavity 111.

[0046] In a preferred embodiment, the main housing 11 is provided with an air inlet 13 and a first air guide interface 14, the air inlet 13 is located on the outer side of the main housing 11, and the first air guide interface 14 is located in the accommodating cavity 111, and a fan 17 is provided between the air inlet 13 and the first air guide interface 14; the cup holder 21 of the processing component 2 is provided with a second air guide interface 212 and an air outlet 213, a heat dissipation channel is provided between the second air guide interface 212 and the air outlet 213, and the motor 214 is located in the heat dissipation channel. When the processing component 2 is inserted and assembled into the accommodating cavity 111, the second coupler 211 of the processing component 2 is coupled and connected with the first coupler 15 of the main unit 1, and the first air guide interface 14 is connected with the second air guide interface 212.

[0047] The fan 17 is electrically connected to the circuit board 16. When the fan 17 is powered on and works, cold air is sucked in from the air inlet 13, and passes through the first air guide interface 14 and the second air guide interface 212 in sequence to enter the heat dissipation channel of the processing component 2 to dissipate heat for the motor 214, and the hot air is finally discharged from the air outlet 213 of the processing component 2. The entire heat dissipation channel is long, the heat dissipation effect is better, and the wind noise is small.

[0048] In addition, the fan 17 is arranged away from the air inlet 13, so that most of the noise generated by the operation of the fan 17 is contained by the main casing 11, and only a small amount of noise can be transmitted from the air inlet 13. However, because the fan 17 is arranged away from the air inlet 13, the transmitted noise is also reduced accordingly, which is beneficial to reduce the noise generated when the food processor is working, ensuring low noise during operation to improve the user experience.

[0049] Preferably, the circuit board 16 is located between the air inlet 13 and the fan 17. Specifically, the circuit board 16 is arranged close to the air inlet 13 to ensure that the cold air sucked from the air inlet 13 first dissipates heat for the circuit board 16, thereby using one fan 1 to dissipate heat for the host 1 and the processing component 2 at the same time, with a simple structure and better heat dissipation effect.

[0050] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
