Description

Technical Field

[0001] This utility model relates to the field of household appliance technology, specifically to a food processing machine with good noise reduction effect. Background Technology

[0002] Existing food processors typically include a main unit, a grinding cup containing a stirring element within the main unit, a motor driving the stirring element, and a water tank connected to the grinding cup. Users place ingredients into the grinding cup, and water is automatically added via the water tank. The stirring element is then activated to process the ingredients. However, the grinding cup in existing food processors is exposed, and noise generated inside the cup can be projected through the feeding lid or the cup wall, resulting in significant noise when the machine is operating. To address this issue, the applicant's earlier patent application CN214964814U discloses a food processor with an optimized noise reduction structure. A fixed wall is provided on the end face of the main unit, forming an upper cavity that accommodates the cup, surrounding at least a portion of the cup. A water tank is mounted around at least a portion of the fixed wall on the main unit. The fixed wall and water tank form a multi-layered sound insulation structure around the cup, achieving noise reduction. However, since the upper cavity formed by the fixed wall for accommodating the cup is not a closed cavity, noise can still easily propagate through open assembly gaps, resulting in poor noise isolation.

[0003] To address the aforementioned issues, another patent of the applicant, CN217524820U, discloses a low-noise food processor. This processor has at least a partially open upper surface on the water tank to form a mating position for installing a vent plug. The vent plug and the mating position are sealed together to form a closed space within the water tank for accommodating at least a portion of the mixing cup assembly, thus isolating noise within this closed space and achieving a more effective noise reduction. While this solution further improves the overall noise reduction effect, the vent plug is exposed to the outside environment and is a structural component connecting the outside to the inside of the cup. Therefore, noise generated inside the cup is directly transmitted outward through the vent plug, resulting in significant noise reaching the outside and severely impacting the user experience. Utility Model Content

[0004] The purpose of this invention is to provide a food processing machine with good noise reduction effect, in order to solve the problem of how to prevent the vent plug from being exposed to the outside and causing noise to be directly transmitted to the outside, resulting in a large noise level, while the existing food processing machine surrounds the water tank on the outside of the cup body to improve noise reduction.

[0005] To achieve the above objectives, this utility model provides a food processing machine with good noise reduction effect, including a main unit, a grinding cup with a stirring component inside the main unit, and a motor for driving the stirring component to rotate. A water tank communicating with the grinding cup is provided on the upper surface of the main unit. The grinding cup includes a cup body located inside the main unit and a cup lid covering the cup body, with the cup lid protruding from the upper surface of the main unit. The bottom wall of the water tank includes a support part abutting against the upper surface of the main unit and an upwardly recessed cavity in the middle. The cup lid is located in the cavity. The cup lid and the water tank are provided with a mutually sealing fit and an exhaust channel connecting the cup body to the outside.

[0006] This application significantly reduces the lateral dimensions of the food processor by placing the water tank on the upper surface of the main unit, allowing users to flexibly place the machine in smaller spaces and improving the user experience. Simultaneously, water in the tank can directly enter the grinding cup by gravity, eliminating the need for a separate water pump to transport water from the tank to the grinding cup, simplifying the overall design, reducing production costs, and further improving the machine's compactness. Furthermore, the bottom wall of the water tank includes a support portion abutting against the upper surface of the main unit and a recessed cavity in the center. The cup lid is located within this cavity, allowing the water tank to act as a soundproof cover for the lid. Compared to existing lids that are directly exposed to the outside, this design completely isolates the lid from the outside environment, effectively reducing noise transmission during grinding and significantly improving noise reduction. Additionally, the lid and water tank have a sealed venting channel connecting the cup body to the outside, allowing steam generated during food processing to escape, preventing pressure buildup and ensuring safe operation. Meanwhile, as noise propagates outward through the exhaust channel, its placement on the lid and water tank significantly extends the channel's length, thus lengthening the noise's path. The noise gradually attenuates over distance, further enhancing noise reduction. Furthermore, the sealed fit between the lid and water tank ensures the exhaust channel remains airtight during exhaust, preventing liquid or vapor leakage between the tank and lid and potential contamination, effectively improving the overall hygiene and safety of the device.

[0007] In a preferred embodiment of a food processor with good noise reduction effect, the exhaust channel includes a first exhaust port located on the cup lid and communicating with the cavity, and a second exhaust port located in the water tank and communicating with the cavity and the outside. The food processor is also provided with a sealing element that seals and communicates the first exhaust port and the second exhaust port.

[0008] By configuring the exhaust channel to include a first exhaust port on the lid that communicates with the cavity and a second exhaust port in the water tank that connects the cavity to the outside, the first and second exhaust ports align and form a complete exhaust channel connecting the outside to the inside of the cup after the water tank is placed in position. This allows steam generated during food processing to be discharged to the outside through the first and second exhaust ports, effectively preventing safety hazards caused by excessive pressure inside the crushing cup. Simultaneously, the food processor is equipped with a sealing element that tightly connects the first and second exhaust ports, ensuring that steam does not leak out through the gap between them as it flows from the first to the second exhaust port, thus ensuring that steam can be smoothly discharged to the outside through the exhaust channel.

[0009] In a preferred embodiment of a food processing machine with good noise reduction effect, the water tank includes a box body forming a cavity and a support, and a cover covering the top of the box body. The second vent includes a first through hole on the box body and a second through hole on the cover. A sealing element seals between the first through hole and the second through hole, and seals between the first through hole and the first vent.

[0010] By setting the seal between the first through hole and the second through hole, and between the first through hole and the first vent hole, multiple sealing connections between the first through hole and the second through hole, as well as between the first through hole and the first vent hole, are achieved with a single seal. This eliminates the cumbersome structure that requires separate seals between the first through hole and the second through hole, and between the first through hole and the first vent hole. This effectively simplifies the structural components, reduces assembly difficulty, and improves the overall sealing reliability. At the same time, it reduces the risk of leakage that may result from the splicing of multiple components.

[0011] In a preferred embodiment of a food processing machine with good noise reduction effect, the sealing element includes a sleeve ring fitted on the inner wall of the first through hole, an overlapping ring extending upward from the sleeve ring and overlapping the upper port of the first through hole, and a sealing ring extending downward from the sleeve ring and inclined outward. The bottom end of the second through hole abuts against the overlapping ring, and the top end of the first vent hole abuts against the sealing ring.

[0012] By configuring the sealing element as a sleeve ring fitted inside the inner wall of the first through hole, an overlapping ring extending upward from the sleeve ring and overlapping the upper end of the first through hole, and a sealing ring extending downward from the sleeve ring and inclined outward, the first through hole and the second through hole can achieve a sealed fit through the overlapping ring after the cover is closed on the tank and the water tank is in place. Simultaneously, the first vent hole and the first through hole can achieve a sealed fit through the sealing ring, thereby ensuring reliable airtightness of the venting channel at multiple connection points and effectively preventing steam leakage. Furthermore, the inclined structure of the sealing ring can produce moderate elastic deformation during water tank assembly, enhancing the fit with the periphery of the first vent hole, further improving the sealing effect, and reducing the risk of material fatigue due to long-term thermal expansion and contraction.

[0013] In a preferred embodiment of a food processing machine with good noise reduction effect, the first exhaust port and the second exhaust port are vertically aligned.

[0014] By aligning the first and second exhaust ports vertically, steam can be smoothly discharged vertically, reducing flow resistance and eddy current generation, thereby lowering noise caused by airflow disturbance during exhaust. Furthermore, it reduces the structural complexity required to seal and connect the first and second exhaust ports, improving assembly efficiency and reducing production costs.

[0015] In a preferred embodiment of a food processing machine with good noise reduction effect, the cup lid includes a body connected to the cup body and a gripping part protruding upward from the middle of the body, and the cavity includes a first cavity adapted to the body and a second cavity adapted to the gripping part.

[0016] By designing the cup lid to include a main body connected to the cup body and a grip protruding upwards from the center of the main body, the cup lid can be securely connected to the cup body via the main body. The protruding structure of the grip facilitates opening and closing for the user, especially in high-temperature steam environments, avoiding the risk of burns from hand contact and improving safety and user experience. Furthermore, the cavity design includes a first cavity adapted to the main body and a second cavity adapted to the grip. On one hand, the first and second cavities achieve a perfect fit with the cup lid, ensuring precise positioning and stable limiting of the cup lid and water tank in both radial and axial directions, guaranteeing the stability of the connection between the water tank and the main unit. On the other hand, it maximizes the water tank's volume, increasing water storage capacity within a limited space, enhancing the continuous working capacity of the food processor, and improving the user experience.

[0017] In a preferred embodiment of a food processing machine with good noise reduction effect, the outer wall of the grip part is provided with multiple anti-slip ribs that extend vertically and are spaced apart circumferentially.

[0018] By providing multiple vertically extending and circumferentially spaced anti-slip ribs on the outer wall of the grip, the friction of the hand when gripping can be significantly increased, preventing slippage. Especially in humid or high-temperature environments, it can still maintain good controllability and improve the user experience.

[0019] In a preferred embodiment of a food processing machine with good noise reduction effect, the water tank includes a box body forming a cavity and a support part, and a cover covering the top of the box body. The cover is provided with a pressure relief hole connecting the inside of the box body to the outside.

[0020] By incorporating a pressure relief vent in the lid that connects the inside of the tank to the outside, the vent ensures pressure balance between the inside and outside of the tank as water flows into the cup. This prevents negative pressure from hindering water flow and ensures a stable and reliable water supply. Furthermore, the pressure relief vent prevents safety hazards caused by excessive internal pressure in high-temperature environments, enhancing overall safety.

[0021] In a preferred embodiment of a food processing machine with good noise reduction effect, the cover is provided with an upwardly raised portion, and a pressure relief hole is provided on the raised portion.

[0022] By providing an upward-raised bulge on the lid and placing the pressure relief hole on the bulge, the pressure relief hole is positioned relatively high relative to the lid surface, effectively preventing external liquids or foreign objects from flowing back into the water tank. In particular, if the liquid in the cup overflows through the venting channel, it can prevent the liquid from flowing along the lid surface and entering the water tank through the pressure relief hole, thereby effectively ensuring the cleanliness of the water tank and the normal operation of the water supply system.

[0023] In a preferred embodiment of a food processing machine with good noise reduction effect, the water tank includes a box body forming a cavity and a support, and a cover covering the top of the box body, with an upwardly protruding annular baffle around the periphery of the cover.

[0024] By incorporating an upward-protruding annular baffle around the perimeter of the lid, the baffle effectively prevents overflowing slurry or steam from the cup from flowing along the outer surface of the lid, thus preventing it from spreading to the connection area between the water tank and the main unit. This also avoids liquid seeping into electrical interfaces or mechanical mating surfaces, thereby improving the safety and reliability of the equipment. Simultaneously, it enhances the strength of the lid and reduces the risk of structural deformation caused by high-temperature and high-humidity environments, further ensuring sealing performance and long-term durability.

Detailed Implementation

[0027] To more clearly illustrate the overall concept of this utility model, a detailed description will be provided below with reference to the accompanying drawings.

[0028] It should be noted that many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0029] like Figures 1 to 8As shown, this utility model provides a food processing machine with good noise reduction effect, including a main unit 1, a grinding cup with a stirring component 5 inside the main unit 1, and a motor 6 for driving the stirring component 5 to rotate. A water tank 2 communicating with the grinding cup is provided on the upper end surface of the main unit 1. The grinding cup includes a cup body 4 located inside the main unit 1 and a cup lid 3 covering the cup body 4. The cup lid 3 is provided to protrude from the upper end surface of the main unit 1. The bottom wall of the water tank 2 includes a support part abutting against the upper end surface of the main unit 1 and an upward recessed cavity 23 in the middle. The cup lid 3 is located in the cavity 23. The cup lid 3 and the water tank 2 are provided with a mutual sealing fit and an exhaust channel communicating with the cup body 4 and the outside.

[0030] This application significantly reduces the lateral dimensions of the food processor by placing the water tank 2 on the upper surface of the main unit 1, allowing users to flexibly place the machine in a smaller space and improving the user experience. Simultaneously, water in the water tank 2 can directly enter the grinding cup by gravity, eliminating the need for a separate water pump to transport water from the tank 2 to the grinding cup, simplifying the overall design, reducing production costs, and further improving the machine's compactness. Furthermore, the bottom wall of the water tank 2 includes a support portion abutting against the upper surface of the main unit 1 and a recessed cavity 23 in the middle. The cup lid 3 is located within the cavity 23, allowing the water tank 2 to act as a soundproof cover for the cup lid 3. Compared to existing methods where the cup lid 3 is directly exposed to the outside, this completely isolates the cup lid 3 from the outside environment, effectively isolating noise within the cavity 23 and significantly reducing the outward transmission of noise during grinding, thus significantly improving noise reduction. Meanwhile, the lid 3 and water tank 2 are equipped with a mutually sealing exhaust channel that connects the cup body 4 to the outside. This allows steam generated during food processing to escape through the exhaust channel, preventing pressure buildup and ensuring safe use. Furthermore, as noise propagates through the exhaust channel, its placement on the lid 3 and water tank 2 significantly extends the channel's length, thus lengthening the noise's path to the outside. The noise gradually attenuates over distance, further enhancing noise reduction. The sealed fit between the lid 3 and water tank 2 ensures the exhaust channel remains airtight during exhaust, preventing liquid or steam leakage between the water tank 2 and lid 3 and causing contamination, effectively improving the overall hygiene and safety of the machine.

[0031] As a preferred embodiment of this application, such as Figure 3 , Figure 4 As shown, the exhaust channel includes a first exhaust hole 31 located on the cup lid 3 and connected to the cavity 23, and a second exhaust hole 24 located on the water tank 2 and connected to the cavity 23 and the outside. The food processing machine is also provided with a sealing element 7 that seals and connects the first exhaust hole 31 and the second exhaust hole 24.

[0032] By configuring the exhaust channel to include a first exhaust port 31 located on the cup lid 3 and communicating with the cavity 23, and a second exhaust port 24 located on the water tank 2 and communicating with the cavity 23 and the outside, the first exhaust port 31 and the second exhaust port 24 are aligned and fitted together after the water tank 2 is placed in position, forming a complete exhaust channel communicating with the outside and the inside of the cup body 4. This allows steam generated during food processing to be discharged to the outside through the first exhaust port 31 and the second exhaust port 24, effectively avoiding safety hazards caused by excessive pressure inside the crushing cup. Simultaneously, the food processor is also equipped with a sealing element 7 that seals the first exhaust port 31 and the second exhaust port 24, ensuring that steam does not leak out through the gap between them during the process of steam being discharged from the first exhaust port 31 to the second exhaust port 24, ensuring that steam can be smoothly discharged to the outside through the exhaust channel.

[0033] It should be noted that this application does not specifically limit the structure of the seal 7. As one preferred embodiment of this application, such as... Figure 4 , Figure 5 As shown, the water tank 2 includes a tank body 21 forming a cavity 23 and a support portion, and a cover body 22 covering the top of the tank body 21. The second vent 24 includes a first through hole 241 provided on the tank body 21 and a second through hole 242 provided on the cover body 22. The sealing member 7 seals between the first through hole 241 and the second through hole 242, and seals between the first through hole 241 and the first vent 31.

[0034] By setting the seal 7 to seal between the first through hole 241 and the second through hole 242, and between the first through hole 241 and the first vent hole 31, multiple sealing connections between the first through hole 241 and the second through hole 242, and between the first through hole 241 and the first vent hole 31, are achieved with a single seal 7. This eliminates the cumbersome structure that requires setting seals 7 separately between the first through hole 241 and the second through hole 242, and between the first through hole 241 and the first vent hole 31. This effectively simplifies the structural components, reduces assembly difficulty, and improves the overall sealing reliability. At the same time, it reduces the risk of leakage that may result from the splicing of multiple components.

[0035] Furthermore, such as Figure 5 As shown, the sealing element 7 includes a sleeve ring 71 fitted on the inner wall of the first through hole 241, an overlapping ring 72 extending upward from the sleeve ring 71 and overlapping the upper port of the first through hole 241, and a sealing ring 73 extending downward from the sleeve ring 71 and inclined outward. The bottom end of the second through hole 242 abuts against the overlapping ring 72, and the top end of the first vent hole 31 abuts against the sealing ring 73.

[0036] By configuring the sealing element 7 as including a sleeve ring 71 fitted inside the inner wall of the first through hole 241, an overlapping ring 72 extending upward from the sleeve ring 71 and overlapping the upper end of the first through hole 241, and a sealing ring 73 extending downward from the sleeve ring 71 and inclined outward, after the cover 22 is closed on the tank 21 and the water tank 2 is placed in position, the first through hole 241 and the second through hole 242 can achieve a sealed fit through the overlapping ring 72. At the same time, the first vent 31 and the first through hole 241 can achieve a sealed fit through the sealing ring 73, thereby ensuring that the vent passage maintains reliable airtightness at multiple connection points and effectively preventing steam leakage. Furthermore, the inclined structure of the sealing ring 73 can produce moderate elastic deformation during the assembly of the water tank 2, enhancing the fit with the periphery of the first vent 31, further improving the sealing effect, and reducing the risk of material fatigue due to long-term thermal expansion and contraction.

[0037] Furthermore, such as Figure 5 As shown, the inner wall of the first through hole 241 is provided with an inwardly extending annular rib, and the sleeve ring 71 includes a stepped portion sleeved on the outside of the annular rib. Meanwhile, the wall of the second through hole 242 is provided with a downwardly extending annular limiting rib. The bottom end of the limiting rib abuts against the upper surface of the stepped portion, and the outer wall abuts against the inner wall of the sleeve ring 71, thereby achieving a multi-seal fit between the first through hole 241 and the second through hole 242 and improving the sealing performance of both.

[0038] It should be noted that this application does not specifically limit the relative positional relationship between the first exhaust port 31 and the second exhaust port 24. As a preferred embodiment of this application, such as... Figure 5 As shown, the first exhaust port 31 and the second exhaust port 24 are aligned vertically.

[0039] By aligning the first vent 31 and the second vent 24 vertically, steam can be smoothly discharged vertically, reducing flow resistance and eddy current generation, thereby reducing noise caused by airflow disturbance during exhaust. Furthermore, it reduces the structural complexity required to seal and connect the first vent 31 and the second vent 24, improving assembly efficiency and reducing production costs.

[0040] As a preferred embodiment of this application, such as Figure 4 As shown, the cup lid 3 includes a body 32 connected to the cup body 4 and a gripping part 33 protruding upward from the middle of the body 32. The cavity 23 includes a first cavity 231 adapted to the body 32 and a second cavity 232 adapted to the gripping part 33.

[0041] By configuring the cup lid 3 to include a body 32 connected to the cup body 4 and a gripping part 33 protruding upward from the middle of the body 32, the cup lid 3 can be stably connected to the cup body 4 through the body 32. At the same time, the protruding structure of the gripping part 33 facilitates the user's opening and closing operation, especially avoiding the risk of hand burns in high-temperature steam environments, thus improving safety and human-machine interaction. Furthermore, the cavity 23 includes a first cavity 231 adapted to the body 32 and a second cavity 232 adapted to the gripping part 33. On the one hand, the first cavity 231 and the second cavity 232 can achieve a perfect fit with the cup lid 3, thereby enabling the cup lid 3 and the water tank 2 to achieve precise positioning and stable limiting in both the radial and axial directions, ensuring the stability of the connection and cooperation between the water tank 2 and the main unit 1. On the other hand, it can maximize the volume of the water tank 2, increase the water storage capacity in a limited space, enhance the continuous working capacity of the food processor, and improve the user experience.

[0042] Furthermore, such as Figure 6 As shown, the outer wall of the grip portion 33 is provided with multiple vertically extending and circumferentially spaced anti-slip ribs 331.

[0043] By providing multiple vertically extending and circumferentially spaced anti-slip ribs 331 on the outer wall of the grip 33, the friction of the hand when gripping can be significantly increased, preventing slippage. Especially in humid or high-temperature environments, it can maintain good operability and improve the user experience.

[0044] Furthermore, the diameter of the grip portion 33 is not less than 80mm, the height is not less than 15mm, and the spacing between the anti-slip ribs 331 is not less than 8mm and not more than 10mm.

[0045] As a preferred embodiment of this application, such as Figure 7 , Figure 8 As shown, the water tank 2 includes a box body 21 forming a cavity 23 and a support part, and a cover 22 covering the top of the box body 21. The cover 22 is provided with a pressure relief hole 221 that connects the inside of the box body 21 with the outside.

[0046] By providing a pressure relief hole 221 on the cover 22 to connect the inside of the tank 21 with the outside, the pressure relief hole 221 can balance the air pressure inside and outside the water tank 2 when water flows into the cup 4, preventing negative pressure from hindering the smooth flow of water and ensuring a stable and reliable water supply. At the same time, the pressure relief hole 221 can prevent safety hazards caused by excessive internal air pressure in the water tank 2 under high temperature environments, thus improving overall safety.

[0047] It should be noted that this application does not specifically limit the location of the pressure relief hole 221. As one preferred embodiment of this application, such as... Figure 7 , Figure 8As shown, the cover 22 has an upwardly raised portion 223, and a pressure relief hole 221 is provided on the raised portion 223.

[0048] By providing an upwardly raised portion 223 to the cover 22 and a pressure relief hole 221 on the raised portion 223, the pressure relief hole 221 is positioned relatively high relative to the surface of the cover 22, effectively preventing external liquids or foreign objects from flowing back into the water tank 2. In particular, if the slurry in the cup 4 overflows through the venting channel, it can prevent the liquid from flowing along the surface of the cover 22 and entering the water tank 2 through the pressure relief hole 221, thereby effectively ensuring the cleanliness of the inside of the water tank 2 and the normal operation of the water supply system.

[0049] As a preferred embodiment of this application, such as Figure 7 As shown, the water tank 2 includes a tank body 21 forming a cavity 23 and a support portion, and a cover 22 covering the top of the tank body 21. The cover 22 is provided with an upwardly protruding annular baffle portion 222 around its perimeter.

[0050] By providing an upward-protruding annular baffle 222 around the perimeter of the cover 22, the annular baffle 222 can effectively prevent the overflowing slurry or steam from the cup 4 from flowing along the outer surface of the cover 22, preventing it from spreading to the connection area between the water tank 2 and the main unit 1, and avoiding liquid seepage into electrical interfaces or mechanical mating surfaces, thereby improving the safety and reliability of equipment operation. At the same time, it can also increase the strength of the cover 22 and reduce the risk of structural deformation caused by high temperature and high humidity environments, further ensuring sealing performance and long-term durability.
