Description

Technical Field

[0001] This application belongs to the field of household appliance technology, specifically relating to a food processing machine with good waterproof performance. Background Technology

[0002] In existing technologies, food processing machines, such as hand-washing blenders and handless soy milk makers, typically use water from an external water tank to transport water through pipes and check valves to the grinding chamber to grind ingredients. After the ingredients are processed, the slurry or wastewater is discharged into a receiving cup and a residual water box by a reversing valve assembly system. The main components for slurry and wastewater discharge are a rotary valve motor that drives gears and a valve core in conjunction with a slurry discharge detection plate. However, during the slurry and wastewater discharge process, water vapor rises from the discharge nozzle and enters the machine body. This causes the rotary valve motor and slurry discharge detection plate located near the discharge nozzle to be affected by the water vapor. The water vapor on the surface causes short circuits in the components, resulting in frequent failure alarms and malfunctions in the food processing machine during the slurry discharge process.

[0003] Chinese utility model patent CN208192930U discloses a food processing machine, which includes a grinding cup and a drain valve. The grinding cup has a discharge port at its bottom, and the drain valve is fixed to the bottom of the grinding cup to control the opening and closing of the discharge port. The drain valve includes a Hall sensor. The Hall sensor is used for non-contact detection of the position of the drain valve, thereby achieving precise detection of the valve position in the food processing machine and accurately controlling the opening and closing of the discharge port, avoiding abnormal pulping caused by incomplete opening or closing of the discharge port. To ensure the accurate operation of the Hall sensor, a waterproof coating is applied to the Hall plate (i.e., the discharge detection plate) of the Hall sensor to prevent the Hall sensor from malfunctioning due to water vapor during the discharge and waste removal process.

[0004] However, the waterproofing method described in the aforementioned patent applies to the vertical arrangement of the rotary valve motor and the slurry discharge detection plate, specifically when the rotary valve motor is connected above the drain valve and the slurry discharge nozzle is located below the slurry discharge detection plate. In this case, the rotary valve motor, being the uppermost of the three components, is farther from the slurry discharge port, and due to the obstruction of the drain valve and the slurry discharge nozzle, it is less affected by water vapor. Therefore, malfunctions can be avoided by waterproofing only the Hall sensor. With the iteration of food processing machine technology, in order to reduce the axial height of the entire machine and improve its operational stability, the rotary valve motor and the drain valve are usually arranged horizontally side by side. In this case, the drain valve cannot provide water vapor protection for the rotary valve motor, resulting in poor waterproofing and making the rotary valve motor susceptible to water vapor, which can lead to transmission failure. Utility Model Content

[0005] This application provides a waterproof food processing machine to solve the problem of how to prevent the rotary valve motor from becoming damp and causing transmission failure when the drain valve and rotary valve motor are placed side by side to reduce the overall height of the food processing machine.

[0006] The technical solution adopted in this application is as follows:

[0007] A waterproof food processing machine includes a machine body, a cup body with a liquid outlet located inside the machine body, a drain valve located outside the cup body, and a receiving cup located below the drain valve. The drain valve includes a valve housing, a valve core installed inside the valve housing, and a rotary valve motor that drives the valve core to rotate to control the opening and closing of the liquid outlet. The rotary valve motor has a waterproof sealing structure on its outer side.

[0008] This solution utilizes a drain valve to discharge the processed slurry or wastewater from cleaning the cup. This eliminates the need for users to manually remove the cup and pour out the slurry; a receiving cup directly collects the liquid, improving user convenience and preventing burns from the hot slurry when removing the cup. Simultaneously, a rotary valve motor controls the rotation of the valve core to open and close the outlet. During operation, the motor isolates the outlet from the outside, preventing slurry from flowing out. When drainage is needed, the motor rotates the valve core away from the outlet, allowing it to open to the outside, and the slurry or wastewater drains through the outlet. The combined action of the rotary valve motor and valve core enables proper drainage from the food processor.

[0009] Furthermore, this application's solution incorporates a waterproof sealing structure on the outside of the rotary valve motor to protect it. Since the receiving cup is located below the drain valve, the liquid temperature is high during slurry and waste discharge from the food processing machine. Water vapor rising from the receiving cup easily enters the drain valve above it, causing condensation on the rotary valve motor and potentially leading to motor malfunction and alarm. The waterproof sealing structure blocks the rising water vapor, preventing condensation on the rotary valve motor surface or entry into the motor, thus providing waterproof protection. This ensures the long-term stable operation of the rotary valve motor, effectively preventing malfunction due to water vapor condensation, and guaranteeing the valve core's control over the outlet, ensuring stable liquid discharge during long-term use of the food processing machine.

[0010] In a preferred embodiment of a food processing machine with good waterproof performance, a detection plate for detecting the rotational position of the valve core is provided above the valve housing, and the waterproof sealing structure also includes a waterproof part that extends outward and seals the detection plate.

[0011] By setting up a detection plate to accurately detect the position of the valve core, the on / off state of the liquid outlet can be precisely controlled, avoiding abnormal discharge or pulping caused by incomplete connection or incomplete closure of the liquid outlet, thus ensuring the reliability of pulping and discharge operations of the food processing machine.

[0012] The outward-extending waterproof section provides waterproof protection for the detection plate, achieving dual waterproofing for both the detection plate and the rotary valve motor. This method integrates the waterproof structures of the detection plate and the rotary valve motor into a single unit, facilitating assembly, improving the overall structural compactness, avoiding interference between components, and enhancing the sealing and waterproofing effect between the detection plate and the rotary valve motor. This prevents condensation from dripping onto the other component when the detection plate and the rotary valve motor are waterproofed separately, thus improving the waterproof protection for both components.

[0013] In a preferred embodiment of a food processing machine with good waterproof performance, the valve housing and the rotary valve motor are arranged side by side, and the waterproof part is a waterproof support with the side wall of the waterproof sealing structure extending outward and sealing and shielding the top of the detection plate.

[0014] With the valve housing and rotary valve motor arranged side-by-side, water vapor rising from the slurry cup can more easily and quickly reach the rotary valve motor through the valve housing into the machine body. The waterproof sealing structure on the outside of the rotary valve motor effectively isolates and blocks the incoming water vapor, preventing condensation and adhesion to the motor, thus providing waterproof protection. The waterproof section extends outwards to form a waterproof bracket that further protects the detection plate. This bracket supports and protects the detection plate from interference from other components, enhancing the structural stability of the waterproof section and further isolating and protecting the internal detection plate, ensuring its accuracy.

[0015] In a preferred embodiment of a food processing machine with good waterproof performance, a waterproof seal and a detection plate for detecting the rotational position of the valve core are provided above the valve housing, and the detection plate is sealed and fixed inside the waterproof seal.

[0016] This implementation method achieves precise detection of the valve core position by setting up a detection plate, thereby accurately controlling the opening and closing of the liquid outlet. This avoids abnormal discharge or pulping caused by incomplete connection or improper closure of the liquid outlet, ensuring the reliability of pulping and discharge operations of the food processing machine. A waterproof seal provides separate waterproof protection for the detection plate, preventing water vapor from entering the discharge valve from the valve body and affecting the detection plate. This prevents water vapor condensation and seepage onto the detection plate, thus avoiding detection failure due to water vapor. The waterproof seal further protects the detection plate from moisture, ensuring its detection reliability and service life.

[0017] In a preferred embodiment of a food processing machine with good waterproof performance, the top wall of the valve body is provided with an upwardly extending limiting post, and the waterproof seal is provided with a limiting groove that is inserted and matched with the limiting post.

[0018] The waterproof seal is fixed and installed by setting a limiting post and a limiting groove. The plug-in connection between the limiting groove and the limiting post is simple and effective, easy to install, and helps to maintain the relative position stability between the waterproof seal and the valve body. This ensures that the detection plate located above the valve body is always waterproofed during the long-term use of the food processing machine, and prevents water vapor from seeping into the detection plate and causing detection failure.

[0019] In a preferred embodiment of a food processing machine with good waterproof performance, the waterproof sealing structure is a sealing sleeve fitted around the rotary valve motor.

[0020] By installing a sealing sleeve to provide circumferential waterproof protection for the rotary valve motor, water vapor is effectively prevented from entering the motor from different directions. This protects the motor from moisture-induced malfunctions and alarms, ensuring stable driving of the valve core and guaranteeing the stability of the food processing machine under various operating conditions, including material processing and waste discharge. Furthermore, as a waterproof sealing structure, the sealing sleeve can be directly fitted onto the outside of the rotary valve motor during assembly, simplifying the process, providing excellent protection, and facilitating widespread adoption.

[0021] In a preferred embodiment of a food processing machine with good waterproof performance, the rotary valve motor includes an upper part and a lower part, the outer diameter of the lower part being larger than that of the upper part to form an upward stepped surface between the upper and lower parts, and the sealing sleeve includes a waterproof sleeve fitted on the outside of the upper part and a waterproof ring covering the step surface.

[0022] The sealing sleeve prevents water vapor from condensing and falling back onto the rotary valve motor through a waterproof sleeve, and achieves abutment assembly with the stepped surface through a waterproof ring. By setting the lower half with an enlarged outer diameter, the rotary valve motor forms an upward-facing stepped surface. The sealing sleeve is fitted and installed to fit the stepped surface, achieving a waterproof seal for the rotary valve motor while the stepped surface provides a limiting assembly for the sealing sleeve, preventing radial displacement of the sealing sleeve due to vibration during rotary valve motor operation. Furthermore, the waterproof ring covers the gap between the upper and lower halves, further preventing condensate from seeping into the rotary valve motor. Thus, the sealing sleeve effectively ensures the waterproof protection of the rotary valve motor and the entire food processing machine during operation.

[0023] In a preferred embodiment of a food processing machine with good waterproof performance, the outer diameter of the waterproof ring is larger than the outer diameter of the step surface.

[0024] By setting the outer diameter of the waterproof ring to be larger than that of the stepped surface, it facilitates the alignment and assembly of the sealing sleeve with the stepped surface, and also enhances the waterproof protection of the lower half of the sealing sleeve. With a larger outer diameter, the end of the waterproof ring extends beyond the stepped surface after assembly. When condensate flows down the waterproof sleeve, it falls along the end of the waterproof ring, creating a distance between it and the end of the stepped surface. This prevents condensate from dripping into the lower half of the rotary valve motor or flowing onto the stepped surface after falling along the end of the waterproof ring, thus further improving the waterproof protection effect of the sealing sleeve on the rotary valve motor.

[0025] In a preferred embodiment of a food processing machine with good waterproof performance, the drain valve further includes a discharge nozzle connected to the valve core, the machine body includes a housing, the housing is provided with a clearance opening for the discharge nozzle to pass through, and a sealing ring is provided between the clearance opening and the discharge nozzle.

[0026] By setting up a valve core that connects to the discharge nozzle, the rotary valve motor drives the valve core to connect or isolate the liquid outlet and the discharge nozzle. During food processing, the rotary valve motor controls the valve core to move to the liquid outlet, positioning it between the liquid outlet and the discharge nozzle to isolate them and prevent slurry leakage. During slurry and waste discharge, the rotary valve motor drives the valve core to move away from the connection between the liquid outlet and the discharge nozzle, allowing the slurry or wastewater to be discharged smoothly through the discharge nozzle. By setting a sealing ring between the clearance port and the discharge nozzle, water vapor is prevented from entering the machine body through the gap between the clearance port and the discharge nozzle when the high-temperature slurry is discharged from the discharge nozzle, and rising to the rotary valve motor or detection plate, which could cause the discharge valve to fail. This further achieves waterproof protection for the rotary valve motor and the detection plate.

[0027] In a preferred embodiment of a food processing machine with good waterproof performance, the sealing ring includes a first sealing part disposed between the clearance port and the discharge nozzle, and a second sealing part disposed at the connection between the discharge nozzle and the valve core.

[0028] By setting a first sealing part, water vapor is prevented from entering the leaching process through the gap between the avoidance port and the discharge nozzle, thus achieving a waterproof seal between the avoidance port and the discharge nozzle. The second sealing part works together with the first sealing part to further prevent water vapor from entering the machine body and rising to the exhaust valve, thereby strengthening the waterproof protection of the exhaust valve. This prevents the rotary valve motor and the detection plate from being affected by the condensation and fall of water vapor, which could lead to structural failure, and ensures the reliability and stability of the exhaust valve assembly.

Furthermore, the specific features, structures, materials, or characteristics described can be combined in any suitable manner in one or more embodiments or examples.

[0042] This application provides a food processing machine with good waterproof performance, such as... Figures 1 to 5 As shown, it includes a body 1, a cup body 2 located inside the body 1 and having a liquid outlet 21, a drain valve 3 located outside the cup body 2, and a receiving cup located below the drain valve 3. The drain valve 3 includes a valve housing 31, a valve core 32 installed inside the valve housing 31, and a rotary valve motor 33 that drives the valve core 32 to rotate to control the opening and closing of the liquid outlet 21. The rotary valve motor 33 is provided with a waterproof sealing structure on its outer side.

[0043] In this solution, the slurry processed inside the cup body 2 or the wastewater after cleaning the cup body 2 is discharged through the drain valve 3. This eliminates the need for the user to manually remove the cup body 2 to pour out the slurry. The slurry is directly collected by the receiving cup, which is convenient for the user and avoids burns from the high temperature slurry when removing the cup body 2, resulting in a better user experience.

[0044] Meanwhile, the rotary valve motor 33 controls the rotation of the valve core 32 to open and close the outlet 21. During the operation of the food processing machine, the rotary valve motor 33 controls the valve core 32 to rotate to isolate the outlet 21 from the outside, preventing the slurry in the cup body 2 from flowing out of the outlet 21 during the processing. When it is necessary to drain the slurry or waste liquid, the rotary valve motor 33 controls the valve core 32 to rotate to avoid the outlet 21, so that the outlet 21 is connected to the outside. The slurry or waste liquid in the cup body 2 is discharged through the outlet 21. The drainage of the food processing machine is achieved by the rotary valve motor 33 and the valve core 32 working together.

[0045] Furthermore, this application's solution incorporates a waterproof sealing structure on the outside of the rotary valve motor 33 to protect it. Since the receiving cup is located below the drain valve 3, the liquid temperature is high during slurry and waste discharge from the food processor. Water vapor rises from the receiving cup and easily enters the drain valve 3 above it, causing condensation on the rotary valve motor 33. This condensation can lead to motor malfunction and alarm. The waterproof sealing structure blocks the rising water vapor, preventing condensation on the surface of the rotary valve motor 33 or its interior, thus providing waterproof protection and ensuring its long-term stable operation. The waterproof sealing structure also enhances the waterproof effect at the drain valve 3 during slurry discharge, preventing motor malfunction due to condensation and ensuring the valve core 32's control over the outlet 21, thus enabling stable slurry discharge during long-term use of the food processor.

[0046] In one embodiment, such as Figure 1 , Figure 2 as well as Figure 5 As shown, a detection plate 4 for detecting the rotational position of the valve core 32 is also provided above the valve housing 31. The waterproof sealing structure also includes a waterproof part that extends outward and seals the detection plate 4.

[0047] By setting up the detection plate 4, the position of the valve core 32 can be accurately detected, thereby accurately controlling the opening and closing of the liquid outlet 21. This avoids abnormal discharge or pulping caused by the liquid outlet 21 not being properly connected or not tightly closed, and ensures the reliability of the pulping and discharge work of the food processing machine.

[0048] The outward-extending waterproof section provides waterproof protection for the detection plate 4, achieving dual waterproofing for both the detection plate 4 and the rotary valve motor 33. This method integrates the waterproof structures of the detection plate 4 and the rotary valve motor 33, facilitating assembly, improving the overall structural compactness, avoiding interference between components, and enhancing the sealing and waterproofing effect between the detection plate 4 and the rotary valve motor 33. This prevents condensation from dripping onto the other component when the detection plate 4 and the rotary valve motor 33 are waterproofed separately, thus improving the waterproof protection effect for both the detection plate 4 and the rotary valve motor 33.

[0049] Furthermore, the valve housing 31 and the rotary valve motor 33 are arranged side by side, and the waterproof part is a waterproof support with the side wall of the waterproof sealing structure extending outward and sealing and blocking above the detection plate 4.

[0050] With the valve housing 31 and rotary valve motor 33 arranged side by side, water vapor rising from the receiving cup can easily and quickly reach the rotary valve motor 33 through the valve housing 31 into the machine body 1. The waterproof sealing structure on the outside of the rotary valve motor 33 effectively isolates and blocks the incoming water vapor, preventing condensation and adhesion to the rotary valve motor 33, thus providing waterproof protection. The waterproof section extends outward to form a waterproof bracket to waterproof the detection plate 4. This bracket supports and protects the detection plate 4 from above, enhancing the structural stability of the waterproof section and further isolating and protecting the internal detection plate 4, preventing interference from other components and ensuring the accuracy of the detection plate 4.

[0051] In a preferred embodiment, such as Figures 1 to 5 As shown, a waterproof seal 5 and a detection plate 4 for detecting the rotational position of the valve core 32 are provided on the upper part of the valve body 31. The detection plate 4 is sealed and fixed inside the waterproof seal 5.

[0052] This implementation uses a detection plate 4 to accurately detect the position of the valve core 32, thereby precisely controlling the opening and closing of the outlet 21. This prevents abnormal discharge or pulping caused by incomplete connection or tight closure of the outlet 21, ensuring the reliability of the pulping and discharge operations of the food processing machine. A waterproof seal 5 provides separate waterproof protection for the detection plate 4, preventing water vapor from entering the drain valve 3 from the valve housing 31 and affecting the detection plate 4. This prevents water vapor condensation and seepage into the detection plate 4, thus avoiding detection failure due to water vapor. The waterproof seal 5 effectively protects the detection plate 4 from moisture, ensuring its detection reliability and service life.

[0053] Furthermore, such as Figure 4 As shown, the top wall of the valve body 31 is provided with an upwardly extending limiting post 311, and the waterproof seal 5 is provided with a limiting groove 51 that is inserted and matched with the limiting post 311.

[0054] The waterproof seal 5 is fixed and positioned by setting the limiting post 311 and the limiting groove 51. The insertion and connection between the limiting groove 51 and the limiting post 311 is simple and effective, easy to install, and helps to maintain the relative position stability between the waterproof seal 5 and the valve body 31. This ensures that the detection plate 4 located above the valve body 31 is always waterproofed during the long-term use of the food processing machine, and prevents water vapor from seeping into the detection plate 4 and causing detection failure.

[0055] In another embodiment, such as Figure 4 As shown, the waterproof sealing structure is a sealing sleeve 6 fitted outside the rotary valve motor 33.

[0056] By installing a sealing sleeve 6 to provide circumferential waterproof protection for the rotary valve motor 33, water vapor is effectively prevented from entering the rotary valve motor 33 from different directions. This protects the rotary valve motor 33 from water vapor affecting it and causing malfunction alarms, ensuring the stable driving effect of the rotary valve motor 33 on the valve core 32. This, in turn, guarantees the stability of the food processing machine under different working conditions, including material processing and slurry / waste discharge. Furthermore, as a waterproof sealing structure, the sealing sleeve 6 can be directly fitted onto the outside of the rotary valve motor 33 during assembly, simplifying assembly, providing good protection for the rotary valve motor 33, and facilitating widespread use.

[0057] Furthermore, such as Figures 1 to 4 As shown, the rotary valve motor 33 includes an upper half 331 and a lower half 332. The outer diameter of the lower half 332 is larger than that of the upper half 331 to form an upward step surface 333 between the upper half 331 and the lower half 332. The sealing sleeve 6 includes a waterproof sleeve 61 fitted on the outside of the upper half 331 and a waterproof ring 62 covering the step surface 333.

[0058] The sealing sleeve 6 prevents water vapor from condensing and falling back onto the rotary valve motor 33 via the waterproof sleeve 61, and achieves abutment assembly with the stepped surface 333 via the waterproof ring 62. By setting the lower half 332 with an enlarged outer diameter, the rotary valve motor 33 forms an upward-facing stepped surface 333. The sealing sleeve 6 is fitted and installed to fit the stepped surface 333, achieving waterproof sealing for the rotary valve motor 33. At the same time, the stepped surface 333 limits the sealing sleeve 6, preventing radial displacement of the sealing sleeve 6 due to vibration during the operation of the rotary valve motor 33. Furthermore, the waterproof ring 62 covers the gap between the upper half 331 and the lower half 332, further preventing condensate from seeping into the rotary valve motor 33. Thus, the sealing sleeve 6 effectively ensures the waterproof protection of the rotary valve motor 33 and the food processing machine as a whole during operation.

[0059] As a preferred embodiment of this example, Figure 3 , Figure 4 As shown, the outer diameter of the waterproof ring 62 is larger than the outer diameter of the step surface 333.

[0060] By setting the outer diameter of the waterproof ring 62 to be larger than that of the stepped surface 333, it facilitates the alignment and assembly of the sealing sleeve 6 with the stepped surface 333, and also enhances the waterproof protection of the lower half 332 provided by the sealing sleeve 6. The larger outer diameter of the waterproof ring 62, after assembly, extends beyond the end of the stepped surface 333. When condensate flows down the waterproof sleeve 61, it falls along the end of the waterproof ring 62, creating a distance between it and the end of the stepped surface 333. This prevents condensate from dripping into the lower half 332 of the rotary valve motor 33 or flowing along the end of the waterproof ring 62 to the stepped surface 333, thus further improving the waterproof protection effect of the sealing sleeve 6 on the rotary valve motor 33.

[0061] In one embodiment, such as Figure 1 , Figure 2 As shown, the drain valve 3 also includes a discharge nozzle 8 that communicates with the valve core 32. The machine body 1 includes a housing, which has a clearance opening for the discharge nozzle 8 to pass through. A sealing ring 7 is provided between the clearance opening and the discharge nozzle 8.

[0062] By setting the discharge nozzle 8 to connect to the valve core 32, the rotary valve motor 33 drives the valve core 32 to achieve connection or isolation between the liquid outlet 21 and the discharge nozzle 8. During food processing, the rotary valve motor 33 controls the valve core 32 to move to the liquid outlet 21, positioned between the liquid outlet 21 and the discharge nozzle 8, achieving isolation between the two and preventing slurry leakage. During slurry discharge and waste discharge, the rotary valve motor 33 drives the valve core 32 to move away from the connection between the liquid outlet 21 and the discharge nozzle 8, allowing the slurry or wastewater to be smoothly discharged through the discharge nozzle 8. By setting a sealing ring 7 between the clearance port and the discharge nozzle 8, water vapor is prevented from entering the machine body 1 through the gap between the clearance port and the discharge nozzle 8 when the high-temperature slurry is discharged from the discharge nozzle 8, and rising to the rotary valve motor 33 or the detection plate 4, causing the discharge valve 3 to fail. This further achieves the waterproof protection effect for the rotary valve motor 33 and the detection plate 4.

[0063] Furthermore, such as Figure 2 As shown, the sealing ring 7 includes a first sealing part 71 disposed between the clearance port and the discharge nozzle 8 and a second sealing part 72 disposed at the connection between the discharge nozzle 8 and the valve core 32.

[0064] By setting the first sealing part 71, water vapor is prevented from entering the leaching process through the gap between the avoidance port and the discharge nozzle 8, thus achieving a waterproof seal between the avoidance port and the discharge nozzle 8. The second sealing part 72 works together with the first sealing part 71 to further prevent water vapor from entering the machine body 1 and rising to the exhaust valve, thereby strengthening the waterproof protection of the exhaust valve. This prevents the rotary valve motor 33 and the detection plate 4 from being affected by the condensation and fall of water vapor, thus ensuring the reliability and stability of the exhaust valve assembly.
