Description

Technical Field

[0001] This utility model belongs to the field of kitchen appliance technology, specifically relating to a food processing machine that cleans thoroughly. Background Technology

[0002] Patent CN218943127U discloses a food processing machine with good cleaning effect. It places a gas-liquid mixer between the gas supply component, water supply component, and the grinding chamber. This allows the gas and liquid to be fully mixed in the gas-liquid mixer with an enlarged cross-sectional area before entering the grinding chamber. Due to the mixing and confluence of the gas and liquid, microbubbles are formed in the water flow. Therefore, the bubble-water carrying the microbubbles enters the grinding chamber, and the impact of the physical bursting of the microbubbles enhances the cleaning effect of the grinding chamber. However, during further research, the applicant discovered that because the gas and water flow are fully mixed in the mixer, the water pressure and velocity discharged from the nozzle are weakened while microbubbles are fully formed, resulting in poor impact rinsing effect. Furthermore, the water flow enters the grinding chamber from the nozzle along a parabolic trajectory. Due to the limited water pressure and velocity, the water flow is difficult to reach the central blade axis of the grinding blade, creating a cleaning blind zone in the center of the grinding blade.

[0003] Although patent CN111481082A discloses an automatic cleaning method for a food processor, which places the water outlet (or nozzle) on the side wall of the grinding cup and diagonally above the grinding blades, with the outlet angled downwards, this method uses the cleaning water sprayed from the outlet to clean the grinding blades. The rotating grinding blades then impact the water flow, accelerating the movement of the cleaning water inside the grinding chamber and washing away the slurry adhering to the inner wall of the grinding chamber, thus improving the self-cleaning effect. However, the impact velocity of the cleaning water exiting the outlet is still limited. The water flows parabolically into the grinding chamber from the outlet, making it difficult to reach the central blade axis, thus creating a cleaning dead zone in the center of the grinding blades and causing incomplete cleaning. Utility Model Content

[0004] This invention provides a food processing machine that cleans thoroughly, solving the technical problem in the prior art where insufficient water flow impact force from the nozzle into the cup prevents the water from reaching the center of the pulverizing blade, creating a cleaning blind zone in the center of the pulverizing blade and resulting in incomplete cleaning of the pulverizing blade.

[0005] The technical solution adopted in this utility model is as follows: This utility model provides a food processor that thoroughly cleans food, including a main unit, a cup body installed on the main unit, a cup lid that fits onto the cup body, and a supply device. The cup body is provided with a pulverizing blade. The food processor also includes a nozzle, which is installed through the side wall of the cup body and has a hollow channel inside. The supply device communicates with the inner cavity of the cup body through the hollow channel. The supply device includes a water supply component and an air supply component that communicate with the hollow channel. The hollow channel includes a first channel, a second channel, and a third channel that are sequentially connected towards the inner cavity of the cup body, and the cross-sectional areas of the first channel, the second channel, and the third channel decrease sequentially. The third channel is inclined downwards towards the pulverizing blade.

[0006] This utility model provides a food processing machine for thorough cleaning. By improving the hollow channel of the nozzle, a simplified structure is achieved without adding extra components. The cross-sectional areas of the first, second, and third channels in the hollow channel decrease sequentially, forming a tapered multi-segment structure. As the cross-sectional area decreases, the water pressure and flow velocity gradually increase through the hollow channel, ultimately culminating in a high-speed jet from the third channel. This provides a strong impact force, solving the problem of insufficient water flow impact and allowing the water to spray a greater distance laterally to thoroughly clean the central area of ​​the pulverizing blade. Simultaneously, the third channel is angled downwards towards the pulverizing blade to guide the water flow. Combined with the increased water flow in the third channel, the water is precisely directed towards the center of the pulverizing blade, expanding the coverage area of ​​the central region and reducing blind spots, thus achieving thorough cleaning of the pulverizing blade.

[0007] In a preferred embodiment, the supply device further includes a three-way pipe, which includes a first interface, a second interface, and a third interface. The first interface, the second interface, and the third interface are respectively connected to the water supply component, the air supply component, and the first channel, thereby forming an alternating water and air pneumatic water flow in the first channel.

[0008] By setting up a three-way pipe, the first, second, and third interfaces of the three-way pipe are connected to the water supply component, the air supply component, and the first channel of the nozzle, respectively. The three-way pipe guides water and air in an orderly manner, forming an alternating water-air aerodynamic water flow. Compared with a single water flow and aerodynamic water mixed with air, this aerodynamic water flow further enhances the impact force of the water flow by the propulsion of the air during the flow process, forming a pulse flow effect. This has a more effective flushing and peeling effect on stubborn slurry and residue on the pulverizer blade and the bottom wall of the cup, making rinsing faster and more efficient. At the same time, the gradually narrowing hollow channel in the nozzle can increase the flow rate, and the aerodynamic water flow can more accurately and powerfully flush and cover the pulverizer blade area, effectively solving the problem of insufficient water flow impact force and incomplete cleaning caused by the blind spot in the center of the pulverizer blade in existing cleaning methods, achieving a more thorough and efficient cleaning effect.

[0009] In a preferred embodiment, the water supply component includes a first pipe connected to the first interface, the gas supply component includes a second pipe connected to the second interface, and a third pipe connects the third interface to the first channel. The inner diameter of the first pipe and the inner diameter of the second pipe are both not less than the inner diameter of the third pipe.

[0010] By guiding water and air into the three-way pipe through the first and second pipes, and then into the third channel through the third pipe, while ensuring that the inner diameters of the first and second pipes are not smaller than the inner diameter of the third pipe, the system prevents water and air from forming fully mixed aerosol water in the third pipe. This also ensures that the air and water can form an orderly water-air alternating pneumatic flow in the hollow channel of the subsequent nozzle, rather than being over-mixed in the third pipe, which would weaken or disable the pneumatic effect. This avoids water pressure loss and ensures that a high-pressure pneumatic water flow is formed at the nozzle, improving the impact and rinsing effect on the pulverizer and cup. It also avoids the problem of insufficient cleaning power causing stubborn slurry to be not thoroughly cleaned, resulting in more thorough and cleaner cleaning with high cleaning efficiency.

[0011] In a preferred embodiment, the length of the first channel is greater than the length of the second channel, and the length of the second channel is greater than the length of the third channel.

[0012] The first channel is longer than the second and third channels, providing more buffer and initial guidance space for the alternating water and air flow from the water supply and air supply components, ensuring that the pneumatic water flow can stably enter the hollow channel of the nozzle. The second channel has a smaller cross-sectional area, ensuring pressurization while being shorter than the first channel, thus avoiding the loss of water pressure and speed. The third channel is further shortened, allowing the water flow pressurized and accelerated by the second channel to be sprayed directly toward the pulverizer, reducing water flow stagnation and pressure attenuation, ensuring that the sprayed water flow has high speed and strong impact, covering the pulverizer area, and improving the cleaning effect on the pulverizer and the cup.

[0013] In a preferred embodiment, the nozzle includes a hollow body and an end wall connected to the end of the body. The side wall of the cup body is provided with a mounting hole. The body is fixed in the mounting hole. The end wall is radially expanded relative to the body and seals against the inner wall of the cup body. The first channel is formed in the body. The second channel and the third channel are provided through the end wall.

[0014] By designing the nozzle as a body and end wall structure, with the body fixed within the mounting hole on the side wall of the cup and the end wall radially enlarged relative to the body and sealingly fitted with the inner wall of the cup, this design prevents fluid leakage from the cup during cleaning through the mounting gap, improving the cup's sealing performance. It also enhances the connection stability between the nozzle and the cup, preventing nozzle displacement during water spraying. Simultaneously, a first channel formed within the body stably receives and transports water, while the second and third channels penetrate the end wall, accelerating and pressurizing the water flow while smoothly guiding it into the cup, allowing the high-pressure water to be sprayed towards the pulverizing blade.

[0015] More preferably, the hollow channel further includes a fourth channel and a fifth channel penetrating the end wall. The first channel, the fourth channel, and the fifth channel are sequentially connected to the inner cavity of the cup body, and the cross-sectional areas of the first channel, the fourth channel, and the fifth channel decrease sequentially. The fifth channel is inclined upward toward the cup lid.

[0016] Based on the nozzle's body and end-wall structure, a fourth and fifth channel, isolated from the second and third channels, are created using the end-wall. This allows the water flow entering the cup through the nozzle to be divided into multiple streams. One stream flows along the first, second, and third channels, cleaning the pulverizer, especially its center. Another stream flows along the first, fourth, and fifth channels. Guided by the upward tilt of the fifth channel towards the cup lid, and with the progressively decreasing cross-sectional areas of the first, fourth, and fifth channels creating a gradual pressurization effect, this not only rinses the cup lid but also guides the water flow towards the center of the lid, expanding the cleaning area and reducing the cleaning blind spot in the center of the lid, thus achieving thorough cleaning of the pulverizer and the cup lid.

[0017] In a preferred embodiment, the nozzle includes an outer section, a middle section, and an inner section formed by sequentially narrowing outer diameters, and the first channel, the second channel, and the third channel are sequentially disposed within the outer section, the middle section, and the inner section.

[0018] More preferably, the side wall of the cup body is provided with a mounting hole, and the inner section is fixed in the mounting hole.

[0019] By configuring the nozzle into an outer section, a middle section, and an inner section with successively tapering outer diameters, and correspondingly providing the first, second, and third channels, the nozzle can be easily formed and is simple to process. Simultaneously, by fixing the inner section within the mounting hole, reliable installation of the nozzle and the cup body is achieved. Furthermore, the small outer diameter of the inner section means that the mounting hole diameter does not need to be too large, thereby reducing the size of the mounting hole, minimizing leakage issues, and improving the sealing effect of the cup body.

[0020] More preferably, the first, second, and third channels are coaxially arranged, thereby further reducing the pressure loss of the water flow and forming a high-pressure water flow at the third channel, which enhances the scouring force and rinsing effect on the cup body and the pulverizing blade.

[0021] In a preferred embodiment, the nozzle includes a support tube and a silicone tube sleeved outside the support tube, and the side wall of the cup body is provided with a mounting hole, the silicone tube being sealed to the mounting hole.

[0022] The nozzle is composed of a support tube and a silicone tube sleeved outside the support tube. The silicone tube forms a flexible fit with the cup body mounting hole to achieve a sealing fit. At the same time, the support tube enhances the overall structural strength of the nozzle, ensuring both the stability of the nozzle installation and the sealing performance between the nozzle and the cup body.

[0023] In a preferred embodiment, one end of the support tube extends outside the silicone tube and is bent downward to connect with the supply device.

[0024] By utilizing the bending of the support tube to connect with the supply device, a smooth transition and docking between the nozzle and the supply device can be achieved. At the same time, it is not necessary to design the entire nozzle by bending, and the pipeline design of the supply device can be simplified. The structure is simplified, and the supply device can deliver the medium from bottom to top. The supply device and the cup are arranged in a reasonable manner to achieve a compact layout of the whole machine structure. Attached Figure Description

In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0032] like Figure 1-6 As shown, in one embodiment of this utility model, a food processor that thoroughly cleans food is provided, including a main unit 10, a cup body 20 installed on the main unit 10, a cup lid 30 covering the cup body 20, and a supply device. A pulverizing blade 60 is provided inside the cup body 20. The food processor also includes a nozzle 50, which is installed through the side wall of the cup body 20 and has a hollow channel inside. The supply device is connected to the inner cavity of the cup body 20 through the hollow channel. The supply device includes a water supply component and an air supply component connected to the hollow channel. The hollow channel includes a first channel 51, a second channel 52, and a third channel 53 that are sequentially connected in the direction of the inner cavity of the cup body 20. The cross-sectional areas of the first channel 51, the second channel 52, and the third channel 53 decrease sequentially. The third channel 53 is inclined downward toward the pulverizing blade 60.

[0033] This utility model does not limit the specific structure of the supply device, such as Figure 1 , 2 As shown, preferably, the water supply assembly includes a water tank 41 installed on the main unit 10 and a water pump 42 connected to the water tank 41, and the air supply assembly includes an air pump 43. Of course, in other embodiments, the water supply assembly is a water supply pipe connected to a kitchen water source.

[0034] like Figure 3 , 4 As shown in Figures 5 and 5, in a preferred embodiment, the first channel 51, the second channel 52, and the third channel 53 have circular cross-sections, as shown in Figure 5. Figure 5 As shown, the inner diameter R1 of the first channel 51, the inner diameter R2 of the second channel 52, and the inner diameter R3 of the third channel 53 decrease sequentially.

[0035] This utility model provides a food processing machine for thorough cleaning. By improving the hollow channel of the nozzle 50, without adding any additional structures, a simplified structure is achieved. The cross-sectional areas of the first channel 51, second channel 52, and third channel 53 in the hollow channel decrease sequentially, forming a tapered multi-segment structure. As the cross-sectional area decreases, the water pressure and flow velocity through the hollow channel gradually increase, ultimately exiting at high speed from the third channel 53 with strong impact force, solving the problem of insufficient water flow impact. This allows the water to spray a greater distance laterally, enabling it to thoroughly clean the central area of ​​the pulverizing blade 60. Simultaneously, the third channel 53 is angled downwards towards the pulverizing blade 60 to guide the water flow. Combined with the accelerated water flow in the third channel 53, the water flow is precisely directed towards the center of the pulverizing blade 60, expanding the coverage area of ​​the central region of the pulverizing blade 60, reducing the cleaning blind spot in the center of the pulverizing blade 60, and achieving thorough cleaning of the pulverizing blade 60.

[0036] In a preferred embodiment, the supply device further includes a tee pipe (not shown), which includes a first interface, a second interface, and a third interface. The first interface, the second interface, and the third interface are respectively connected to the water supply component, the air supply component, and the first channel 51, thereby forming an alternating water and air pneumatic flow within the first channel 51. Optionally, the tee pipe can be Y-shaped or T-shaped.

[0037] More preferably, the water supply component includes a first pipe connected to the first interface, the gas supply component includes a second pipe connected to the second interface, and a third pipe is connected between the third interface and the first channel 51. The inner diameter of the first pipe and the inner diameter of the second pipe are both not less than the inner diameter of the third pipe.

[0038] By setting up a three-way pipe, the first, second, and third interfaces of the three-way pipe are connected to the water supply component, the air supply component, and the first channel 51 of the nozzle 50, respectively. The three-way pipe guides water and air in an orderly manner, forming an alternating water-air aerodynamic water flow. Compared with a single water flow and aerodynamic water mixed with air, this aerodynamic water flow further enhances the impact force of the water flow by the propulsion of the air during the flow process, forming a pulse flow effect. It has a more effective flushing and peeling effect on the stubborn slurry residue on the pulverizer 60 and the bottom wall of the cup 20, making the rinsing faster and more efficient. Combined with the increased flow rate from the gradually narrowing hollow channel inside the nozzle 50, the aerodynamic water flow can more accurately and powerfully cover the area of ​​the pulverizer 60, effectively solving the problem of insufficient water flow impact force and incomplete cleaning caused by the blind spot in the center of the pulverizer 60 in existing cleaning methods, achieving a more thorough and efficient cleaning effect.

[0039] By guiding water and air into the three-way pipe through the first and second pipes, and then into the third channel 53 through the third pipe, while ensuring that the inner diameters of the first and second pipes are not smaller than the inner diameter of the third pipe, water and air are prevented from forming fully mixed aerated water in the third pipe. This also ensures that air and water can form an orderly water-air alternating pneumatic flow in the hollow channel of the subsequent nozzle 50, rather than being over-mixed in the third pipe, which would weaken or disable the pneumatic effect. This avoids water pressure loss and ensures that a high-pressure pneumatic flow is formed at the nozzle 50, improving the impact and scouring effect on the pulverizer 60 and the cup 20. It also avoids the problem of insufficient cleaning power causing stubborn slurry to not be thoroughly cleaned, resulting in more thorough and cleaner cleaning with high cleaning efficiency.

[0040] In addition, combined Figure 3 , 5 As shown, in a preferred embodiment, the length of the first channel 51 is greater than the length of the second channel 52, and the length of the second channel 52 is greater than the length of the third channel 53.

[0041] The first channel 51 is longer than the second channel 52 and the third channel 53, providing more buffer and initial guidance space for the alternating water and air flow from the water supply component and the air supply component, ensuring that the air flow can stably enter the hollow channel of the nozzle 50. The second channel 52 has a smaller cross-sectional area, which ensures pressurization while being shorter than the first channel 51, thus avoiding the loss of water pressure and speed. The third channel 53 is further shortened, allowing the water flow that has been pressurized and accelerated by the second channel 52 to be sprayed directly toward the pulverizer 60, reducing water flow stagnation and pressure attenuation, ensuring that the sprayed water flow has high speed and strong impact, covering the area of ​​the pulverizer 60, and improving the cleaning effect on the pulverizer 60 and the cup body 20.

[0042] It should be noted that this utility model does not limit the specific structure of the nozzle 50, such as... Figure 6 As shown, the nozzle 50 includes a hollow body and an end wall connected to the end of the body. The side wall of the cup body 20 is provided with a mounting hole. The body is fixed in the mounting hole. The end wall is radially expanded relative to the body and is sealed to the inner wall of the cup body 20. The first channel 51 is formed in the body. The second channel 52 and the third channel 53 are provided through the end wall.

[0043] Combination Figure 3 As shown, more preferably, the main body of the nozzle 50 includes a support tube 501 and a silicone tube 502 sleeved outside the support tube 501. The silicone tube 502 is integrally formed with the end wall. The side wall of the cup body 20 is provided with an installation hole. The silicone tube 502 is sealed to the installation hole. The first channel 51 is located inside the support tube 501. The second channel 52 and the third channel 53 are provided through the end wall.

[0044] More preferably, one end of the support tube 501 extends out of the silicone tube 502 and bends downward to connect with the supply device.

[0045] The nozzle 50 is composed of a support tube 501 and a silicone tube 502 sleeved outside the support tube 501. The silicone tube 502 forms a flexible fit with the mounting hole of the cup body 20 to achieve a sealing fit. At the same time, the support tube 501 enhances the overall structural strength of the nozzle 50, ensuring the stability of the nozzle 50 installation and the sealing performance between the nozzle 50 and the cup body 20. By bending the support tube 501 to connect with the supply device, a smooth transition and docking between the nozzle 50 and the supply device is achieved. This eliminates the need for a complete bending design of the nozzle 50 and simplifies the piping design of the supply device, resulting in a simplified structure. Furthermore, the supply device enables bottom-up medium delivery, and the rational arrangement of the supply device and the cup body 20 achieves a compact overall structure.

[0046] By configuring the nozzle 50 as a body and end wall structure, with the body fixed in the mounting hole on the side wall of the cup 20 and the end wall radially enlarged relative to the body and sealingly fitted with the inner wall of the cup 20, fluid leakage from the cup 20 during cleaning can be prevented from seeping through the mounting gap, improving the sealing performance of the cup 20. Furthermore, it enhances the connection stability between the nozzle 50 and the cup 20, preventing displacement of the nozzle 50 during water spraying. Simultaneously, the first channel 51 is formed within the body, stably receiving and transporting water flow. The second channel 52 and the third channel 53 penetrate the end wall, accelerating and pressurizing the water flow while smoothly guiding it into the cup 20, causing the high-pressure water flow to spray towards the pulverizer 60.

[0047] Of course, in other embodiments of this invention, the nozzle 50 is a silicone tube or a rigid tube.

[0048] In addition, it should be noted that this utility model does not limit the number of hollow channels in the nozzle 50.

[0049] like Figure 3 , 4 As shown in Figures 6 and 7, in a preferred embodiment, the first channel 51, the second channel 52, and the third channel 53 are sequentially connected to form a first hollow channel. The hollow channel also includes a fourth channel 54 and a fifth channel 55 penetrating through the end wall. The first channel 51, the fourth channel 54, and the fifth channel 55 are sequentially connected to the inner cavity of the cup body 20 to form a second hollow channel. The cross-sectional areas of the first channel 51, the fourth channel 54, and the fifth channel 55 decrease sequentially. The fifth channel 55 is inclined upward toward the cup lid 30, so that the second hollow channel is used to spray water toward the cup lid 30 for cleaning.

[0050] Based on the body and end wall structure of the nozzle 50, a fourth channel 54 and a fifth channel 55, isolated from the second channel 52 and the third channel 53, are set up on the end wall. Therefore, the water flow entering the cup body 20 through the nozzle 50 is divided into multiple streams. One stream (the water flow in the first hollow channel) flows along the first channel 51, the second channel 52, and the third channel 53, towards the pulverizer 60, especially cleaning the center of the pulverizer 60. The other stream (the water flow in the second hollow channel) flows along the first channel 51, the fourth channel 54, and the fifth channel 55. Under the guiding effect of the fifth channel 55 tilting upward towards the cup lid 30, and under the effect of the progressively decreasing cross-sectional area of ​​the first channel 51, the fourth channel 54, and the fifth channel 55 forming a step-by-step pressurization, it not only rinses the cup lid 30, but also guides the water flow towards the central area of ​​the cup lid 30, expanding the cleaning area of ​​the cup lid 30 and reducing the cleaning blind spot in the center of the cup lid 30, thus achieving thorough cleaning of the pulverizer 60 and the cup lid 30.

[0051] More preferably, combined with Figure 4 The hollow channel also includes a sixth channel and a seventh channel 56 penetrating the end wall. The cross-sectional areas of the first channel 51, the sixth channel (not shown), and the seventh channel 56 decrease sequentially and are connected to form a third hollow channel. The seventh channel 56 is arranged laterally or at an angle to flush towards the inner wall of the cup body 20. Thus, combined with... Figure 3 As shown, when the air supply component and water supply component are working, an alternating air-water flow is formed in the first channel 51. The air-water flow is accelerated and discharged through the first hollow channel, the second hollow channel and the third hollow channel to form three cleaning water flows, which respectively rinse the center of the crushing blade, rinse the cup lid (center) and rinse the inner side wall of the cup, so as to achieve thorough cleaning and remove stubborn slurry residue.

[0052] Understandably, in other embodiments, more hollow channels can be provided on the nozzle to clean the cup from more angles.

[0053] Of course, the nozzle 50 structure provided by this utility model is not limited to the one described above. In another preferred embodiment, the nozzle 50 includes an outer section, a middle section, and an inner section formed by sequentially narrowing outer diameters, with a first channel 51, a second channel 52, and a third channel 53 sequentially disposed within the outer section, the middle section, and the inner section. More preferably, a mounting hole is provided on the side wall of the cup body 20, and the inner section is fixed within the mounting hole; even more preferably, the first channel 51, the second channel 52, and the third channel 53 are coaxially arranged.

[0054] By configuring the nozzle 50 into an outer section, a middle section, and an inner section with sequentially tapering outer diameters, and correspondingly providing a first channel 51, a second channel 52, and a third channel 53, the nozzle 50 can be easily formed and its processing is simple. Simultaneously, by fixing the inner section within the mounting hole, reliable installation of the nozzle 50 and the cup body 20 is achieved. Furthermore, the small outer diameter of the inner section means that the diameter of the mounting hole does not need to be too large, thereby reducing the size of the mounting hole, minimizing leakage problems, and improving the sealing effect of the cup body 20.

[0055] The first channel 51, the second channel 52, and the third channel 53 are coaxially arranged, thereby further reducing the pressure loss of the water flow. High-pressure water flow is formed at the third channel 53, which enhances the flushing force and rinsing effect on the cup body 20 and the pulverizer 60.

[0056] For any parts not mentioned in this utility model, existing technologies can be used or referenced.

[0057] The various embodiments in this specification are described in a progressive manner. The same or similar parts between the various embodiments can be referred to each other. Each embodiment focuses on describing the differences from other embodiments.

[0058] The above description is merely an embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of this utility model should be included within the scope of the claims of this utility model.
