Description

Technical Field

[0001] The invention relates to the field of food processing electrical appliances, in particular to a food processor with high processing efficiency and thorough cleaning. Background Art

[0002] Food processors, such as food processors and soymilk machines, include a machine base, a food container disposed on the machine base, and a processor disposed in the food container (for example, the processor is a blender or a crusher). When in use, the machine base drives the processor to work in the food container, providing a variety of functions such as crushing, stirring, and even steaming ingredients, which are very popular with users. However, after the food is processed, the ingredients will adhere to the inner wall or even the top cover of the food container, requiring manual cleaning, which increases the difficulty of cleaning and affects the user experience.

[0003] Chinese patent CN201610048007X discloses a food processor cleaning machine capable of spraying at multiple angles. A nozzle is provided at the bottom of the inner pot, and an adjustment structure for adjusting the size of the sprayed water flow is installed at the nozzle outlet. Water flow is sprayed from the bottom of the inner pot from bottom to top at multiple angles to clean the inner pot. This technical solution uses multi-angle spraying water flow to clean the lower part of the inner pot and the blade, but the sprayed water flow cannot clean the upper end of the inner wall of the cup body and the inner side of the top cover, and the cleaning effect needs to be further improved; and the spraying water flow angle depends on multiple spray holes with different angles to the horizontal direction. The fixed angle of each spray hole results in that water flow can only be sprayed in a fixed direction, which further limits the cleaning effect. Summary of the invention

To this end, the present invention provides a food processor with efficient processing and thorough cleaning, which can improve the food processing efficiency in the food processing state by using a rotating cleaning device, and can provide a more thorough spray cleaning in the rotating process in the cleaning state.

[0005] The present invention provides a food processor with high processing efficiency and thorough cleaning, comprising a base with a built-in motor, a food container arranged on the base, a container cover that can be covered on the food container, and a processing device arranged in the food container and driven by the motor;

[0006] It also includes a rotating cleaning device connected to an external water source and rotatably arranged above the processing device;

[0007] The rotary cleaning device comprises a processing auxiliary surface arranged near the processing processor and at least one pair of nozzles for generating a driving force couple when spraying water columns to drive the rotary cleaning device to rotate, and the nozzles are arranged away from the processing processor;

[0008] The working states of the food processor include food processing state and cleaning state: in the food processing state, the rotary cleaning device rotates so that the processing auxiliary surface forms a circular blocking surface for blocking food; in the spray cleaning state, the rotary cleaning device rotates under hydraulic drive and sprays a water column through the nozzle toward the upper end of the inner wall of the food container or / and the inner wall of the container cover.

[0009] In a preferred embodiment, the rotary cleaning device is detachably and rotatably mounted on the inner side wall of the container cover, or the rotary cleaning device is rotatably mounted on the top end of the rotating shaft of the processing unit.

[0010] In a preferred embodiment, each nozzle is provided with a one-way valve which is opened only in the spray cleaning state, and the valve opening of the one-way valve is exposed outside the nozzle.

[0011] In a preferred embodiment, the rotary cleaning device includes a spray body, a water inlet joint for connecting to an external water source, and a water channel arranged in the spray body, the water channel is located between the water inlet joint and the nozzle; the nozzle is arranged on the spray body, and the bottom side of the spray body facing the processing processor is a processing auxiliary surface.

[0012] In a preferred embodiment, the water channel is arranged to gradually decrease and extend from the connection with the water inlet joint toward the nozzle.

[0013] In a preferred embodiment, the spray body includes a spray bottom cover and a spray upper cover detachably assembled on the spray bottom cover, and the nozzle is arranged on the spray upper cover; an exhaust hole is arranged on the spray bottom cover, and the exhaust hole is located at the end of the water channel and close to the nozzle.

[0017] In a preferred embodiment, the upper nozzle of each wing is inclined at the same inclination angle toward the driving nozzle on the same wing.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] The present invention arranges a rotatable rotary cleaning device above the processing unit in the processing container, arranges the side of the rotary cleaning device close to the processing unit as a processing auxiliary surface, and utilizes the processing auxiliary surface to selectively form a circular blocking surface for blocking the food when the food processor is in the food processing state.

[0028] 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.

[0029] like Figure 1 As shown, the present invention discloses a food processor with efficient processing and thorough cleaning, comprising a machine base 1 with a built-in motor 19, a food container 21 arranged on the machine base 1, a container cover 4 that can cover the food container 21, and a processing device 22 arranged in the food container 21 and driven by the motor 19; it also includes a rotating cleaning device 5 connected to an external water source and rotatably arranged above the processing device 22; the rotating cleaning device 5 includes a processing auxiliary surface arranged near the processing device 22 and at least one pair of nozzles for generating a driving force couple when spraying a water column to drive the rotating cleaning device 5 to rotate, and the nozzles are arranged away from the processing device 22.

[0030] Among them, the working status of the food processor includes food processing status and cleaning status.

[0031] In the food processing state, the motor 19 drives the processor 22 to process the food in the food container 21. The food is pushed by the processor 22 to rotate and flip in the food container 21, and hits the processing auxiliary surface of the rotating cleaning device 5 upward, thereby pushing the rotating cleaning device 5 to rotate. The processing auxiliary surface rotates to form a circular blocking surface for blocking the food. The circular blocking surface provides blocking for the food, which can not only prevent the food from continuing to jump upward to reduce the food from adhering to the inner wall of the container cover 4, but also promote the food to roll downward toward the processor 22, thereby increasing the chance of the food being processed by the processor 22 to improve the processing efficiency.

[0032] After the food processing state is completed, after the food is taken out from the food container 21, the food processor can enter the cleaning state as needed, and the cleaning state includes a spray cleaning state and a rotation cleaning state.

[0033] In the spray cleaning state, the rotary cleaning device 5 rotates under hydraulic drive, and sprays a water column from the nozzle toward the upper end of the inner wall of the food container 21 and / or the inner wall of the container cover 4, spraying and flushing the upper end of the inner wall of the food container 21 and / or the inner wall of the container cover 4.

[0034] After the spray cleaning state is completed, the motor 19 is started again to drive the processor 22 to rotate rapidly in the food container 21, so that the processor 22 drives the water flow in the food container 21 to rotate and roll to form a vortex. The vortex will flush and clean the food remaining on the processor 22, the outer surface of the rotary cleaning device 5 (especially the auxiliary processing surface), the lower end of the inner wall of the food container 21 and the bottom, so that the food processor can be thoroughly cleaned.

[0035] The processor 22 generally includes a rotating shaft connected to the motor 19 and a stirrer or a crushing blade arranged on the rotating shaft. When the processor 22 is a stirrer, it provides a function of crushing, stirring and mixing the food in the food container 21 under the drive of the motor 19. When the processor 22 is a crushing blade, it provides a function of chopping and breaking the food in the food container 21 under the drive of the motor 19.

[0036] In one embodiment, the food processing machine further comprises a water tank 31, a water pump 32 and a water pipe 33 connected to the water tank 31 through the water pump 32, and the end of the water pipe 33 is connected to the rotary cleaning device 5. The food processing machine is in a spray cleaning state. The water in the water tank 31 is pumped to the rotary cleaning device 5 by the water pump 32 through the water pipe 33 and the water supply joint 41, and the water is transported to the rotary cleaning device 5 with a certain water pressure. The water enters the waterway 52 of the rotary cleaning device 5, and the water is sprayed from a pair of nozzles toward the upper end of the inner wall of the food container 21 or / and the inner side wall of the container cover 4, forming a pair of force couples to drive the rotary cleaning device 5 to rotate. As the rotary cleaning device 5 rotates, the water column can be sprayed to the upper end of the inner wall of the food container 21 and various positions of the inner side wall of the container cover 4, and the residual food on the upper end of the inner wall of the food container 21 and the inner side wall of the container cover 4 is washed away.

[0037] After the spray cleaning state is completed, the food processor enters the rotating cleaning state, the water pump 32 is turned off, and the motor 19 is started again to drive the processing unit 22 to rotate rapidly in the food container 21, so that the processing unit 22 drives the water flow in the food container 21 to rotate and roll to form a vortex, and the vortex will flush and clean the remaining food on the processing unit 22, the outer surface of the rotating cleaning device 5, the lower end of the inner wall and the bottom of the food container 21.

[0038] After the cleaning state, the interior of the food container 21, the inner wall of the container cover 4, the outer surface of the rotating cleaning device 5 and the processing unit 22 can be completely and thoroughly cleaned, which is beneficial to improve the cleaning effect and enhance the user experience. It also effectively prevents bacteria from growing in cleaning dead corners due to the long-term presence of food residues to ensure hygienic and safe use.

[0039] The rotary cleaning device 5 is rotatably arranged above the processing unit 22, and includes at least two implementation modes: the first one is as follows: Figure 1 and Figure 2 As shown, the rotary cleaning device 5 is detachably rotatably mounted on the inner side wall of the container cover 4; the second embodiment is that the rotary cleaning device 5 is rotatably mounted on the top of the processing device 22, specifically, it is rotatably mounted on the top of the rotating shaft of the processing device 22, and the water pipe 33 is routed inside the rotating shaft. This structure will be relatively complex and puts forward higher requirements on the structure and strength of the processing device 22. Therefore, this application is described in detail in the first manner.

[0040] See Figure 2-Figure 4 The rotary cleaning device 5 specifically comprises a spray body 51, a water inlet joint 53 for connecting to an external water source, and a water channel 52 provided in the spray body 51, wherein the water channel 52 is located between the water inlet joint 53 and the nozzle; wherein the bottom side of the spray body 51 facing the processing processor 22 is a processing auxiliary surface 500, a pair of nozzles are provided on the spray body 51, the water inlet joint 53 is fixed in the middle of the spray body 51, and the spray body 51 has side wings distributed on two opposite sides of the central axis O-O' of the water inlet joint 53 (see Figure 2 As shown, the two side wings are marked as 501 and 502 respectively), and a pair of nozzles are distributed on the two side wings.

[0041] In one embodiment, a through groove and a water outlet joint 41 located in the through groove and connected to an external water source are provided on the inner side wall of the container cover 4 (for example, the water outlet joint 41 is connected to the water tank 31 via a water pipe 33 via a water pump 32); the rotary cleaning device 5 is connected to the water outlet joint 41 via a water inlet joint 53, so that the rotary cleaning device 5 is movably assembled on the inner side wall of the container cover 4, so that the rotary cleaning device 5 can self-rotate about the central axis O-O' of the water inlet joint 53 (wherein the central axis O-O' coincides with the rotation axis of the rotary cleaning device 5, and the two are the same concept), so that during the self-rotation process, the water column sprayed from the nozzle can be used to automatically clean the upper end of the inner wall of the food container 21 or / and the inner side wall of the container cover 4.

[0042] Specifically, a pair of limiting buckles 54 are provided on the spray body 51 at two opposite sides of the water inlet joint 53, a fixing member 42 is provided on the inner side wall of the container cover 4 at the outer side of the water outlet joint 41, and a limiting convex ring 421 is provided on the outer side wall of the fixing member 42, the water inlet joint 53 is plugged and connected with the water outlet joint 41, and the end buckle 541 of the limiting buckle 54 is buckled on the limiting convex ring 421 of the fixing member 42 for limiting, so as to ensure that the water inlet joint 53 and the water outlet joint 41 are kept plugged and connected rotatably, so that the rotating cleaning device 5 is plugged into the water outlet joint 41 according to the water inlet joint 53 and rotates relative to the water outlet joint 41. This structure makes the rotating cleaning device 5 easy to assemble relative to the container cover 4.

[0043] The water channel 52 is gradually reduced and extended from the connection with the water inlet joint 53 toward the nozzle. Specifically, each wing has a connection end 508 connected to the water inlet joint 53 and a spray end 509 away from the connection end 508, the nozzle is set at the spray end 509, and the part of the water channel 52 in each wing 501 and 502 is gradually reduced and extended from the connection end 508 toward the spray end 509. This structure optimizes the water channel structure, so that after the water from the external water source enters the water channel 52 from the water inlet joint 53, the water flows toward the nozzle along the gradually reduced water channel 52, and the water pressure increases continuously during the flow process, and finally a water column is sprayed out from the nozzle with a larger spray force, so that the sprayed water column can produce a better cleaning effect on the food processor.

[0044] Especially see Figure 5 As shown. The spray body 51 includes a spray bottom cover 512 and a spray upper cover 511 detachably mounted on the spray bottom cover 512, and the nozzle is arranged on the spray upper cover 511. In addition, a first water tank is arranged on the lower side of the spray upper cover 511, and a second water tank 5120 is arranged on the upper side of the spray bottom cover 512. The first water tank and the second water tank 5120 have the same extension shape as the waterway 52. ​​When the spray upper cover 511 and the spray bottom cover 512 are assembled and connected, the first water tank and the second water tank 5120 jointly enclose the waterway 52. ​​This structure facilitates the manufacture and assembly of the rotary cleaning device 5, and also facilitates the subsequent cleaning of the waterway 52 by opening the spray upper cover 511, which is conducive to improving the safety of use.

[0045] The water inlet joint 53 is fixed at the center of the spray cover 511, and the water channel 52 has a water channel center connected to the water inlet joint 53, and the water channel center has a larger size; and the water channel 52 extends sub-water channels from the water channel center toward two opposite ends, each sub-water channel is respectively located in each side wing 501 and 502, and each sub-water channel is gradually reduced from the water channel center toward the nozzle; and the end of the water channel 52 close to the nozzle has an arc transition shape, so that the water in the water channel 52 can reduce the resistance according to the arc transition shape to flow to the nozzle more smoothly, ensuring that the water column sprayed from the nozzle has a greater spray force to improve the cleaning ability.

[0046] Furthermore, a one-way valve 7 is provided at each nozzle, and the valve port 73 of the one-way valve 7 is exposed outside the nozzle, so that the rotary cleaning device 5 allows the water in the water channel 52 to flow through the valve port 73 of the one-way valve 7 and spray outward when providing the spray cleaning work. When the food processor is in the spray cleaning state, the rotary cleaning device 5 provides the spray cleaning work for the food processor, and the water flow in the water channel 52 flushes the valve port 73 of the one-way valve 7 from the nozzle and then sprays out from the valve port 73 to clean the food processor; when the food processor is in the food processing state, the rotary cleaning device 5 is not working, and the valve port 73 of the one-way valve 7 is closed, so that when the food processor is used to process and make food, the food will not enter the water channel 52 from the nozzle, and the water channel 52 will not be blocked, causing the rotary cleaning device 5 to fail to work, and the food will not remain in the water channel 52 to breed bacteria, thereby eliminating health and safety hazards.

[0047] The one-way valve 7 includes a valve seat 71 and a valve body 72 disposed on the valve seat 71, and a valve port 73 of the valve body 72 is exposed outside the nozzle. The valve seat 71 is limitedly disposed at the nozzle to block the nozzle, ensuring that the water flow of the water channel 52 can flush the valve port 73 of the one-way valve 7 under pressure and spray out from the valve port 73. The shape of the valve port 73 can be a straight line shape, a thin hole or other shapes, which are not limited here.

[0048] See Figure 8 In the embodiment shown, an exhaust hole 57 is also provided on the shower body 51. The exhaust hole 57 is located at the end of the water channel 52 and is arranged close to the nozzle, so that the air remaining in the water channel 52 can be discharged from the exhaust hole 57, ensuring that the water flow is unobstructed with the outside air when entering the closed water channel 52. It can be understood that the exhaust hole 57 is a capillary pore that allows water to flow out without overcoming the surface tension, and there will be no water leakage. For example, the exhaust hole 57 is arranged on the shower bottom cover 512 and is located at both ends of the second water tank 5120.

[0049] In one embodiment, the nozzle further includes two driving nozzles 56 respectively arranged on two side wings, and each driving nozzle 56 is respectively located on different vertical sides on each side wing (specifically, the two driving nozzles 56 are arranged on different vertical sides of the two side wings of the spray cover 511). The functions of the two driving nozzles 56 include at least: first, water from an external water source flows toward the two driving nozzles 56 after generating water pressure through the water channel 52, and a pair of parallel force couples or driving force couples are generated on the spray body 51 when the two driving nozzles 56 spray out water columns, which drive the spray body 51 to rotate around the central axis O-O', and drive the rotating cleaning device 5 to rotate around the central axis O-O' for spraying, so that the rotating cleaning device 5 can be driven by water power, without external driving components, with a simple structure and reliable operation; second, by using the two driving nozzles 56 arranged on different vertical sides on the two side wings, the water column can be sprayed toward the upper end of the inner wall of the food container, so that the upper end of the inner wall of the food container can be cleaned.

[0050] In one embodiment, the nozzle further includes two upper nozzles 55 respectively arranged on two side wings and connected to the water channel 52, and the upper nozzles 55 are arranged on the spray upper cover 511. The upper nozzles 55 are used to spray water upward to spray and rinse the inner wall of the container cover 4, so that the food processor can be thoroughly cleaned by the rotary cleaning device 5.

[0051] Further integration Figure 6 The number of the upper nozzles 55 is also multiple. Each nozzle 55 is set at an angle with the top surface of the spray body 51 (such as Figure 6 As described above, the top surfaces of the two nozzles 55 and the spray body 51 have angles γ1 and γ2 respectively, so that the water jets from the upper nozzles 55 are intersecting, ensuring that all positions on the inner wall of the container cover 4 can be cleaned. Preferably, each nozzle 55 has an equal angle with the top surface of the spray body 51.

[0052] In a preferred embodiment, the upper nozzle 55 of each wing is tilted toward the driving nozzle 56 located on the same wing at an equal tilt angle (i.e., γ1=γ2). This structure has at least the following advantages: first, the existence of the tilt angle allows the water columns sprayed from the pair of upper nozzles 55 to form a cross, and the crossed water columns are sprayed to a larger area when the cleaning device rotates, thereby achieving a better cleaning effect; second, because the tilt angle is tilted toward the driving nozzle 56, the water columns sprayed from the pair of upper nozzles 55 can increase the parallel force couple that causes the spray body 51 to rotate around the central axis O-O', that is, it can assist the pair of driving nozzles 56 to generate a larger driving force couple on the spray body 51, ensuring that the cleaning device can rotate under the action of water.

[0053] Combine again Figure 4 , Figure 6-Figure 8As shown. In order to allow the rotary cleaning device 5 to self-rotate the central axis O-O' under the action of the driving force couple generated by a pair of driving nozzles 56 without external force driving, in a preferred embodiment, the two side wings located on the two opposite sides of the central axis O-O' have a rotational overlap structure that rotates 180°, that is, the rotational overlap structure means that the outer structure of any one of the side wings completely overlaps with the outer structure of the other second water tank 5120 after rotating 180° clockwise or counterclockwise around the central axis O-O'. This structure enables the rotary cleaning device 5 to have an outer structure that is easy to rotate, which is conducive to a pair of driving force couples of equal size, opposite direction but not collinear when the pair of driving nozzles spray water. The driving force couple is used to drive the spray body 51 to automatically rotate with the central axis O-O' of the water inlet joint as the rotation axis without external force driving, which has the advantages of small rotation resistance, stable rotation and simple structure, and provides a reliable spray cleaning solution for applying the cleaning device to the food processing machine.

[0054] Specifically, the shape and size of each wing conform to a rotational overlap structure rotated 180°; and the shape and size of the driving nozzle 56, the upper nozzle 55 and the exhaust hole 57 provided on each wing and the position characteristics on each wing also conform to a rotational overlap structure rotated 180°.

[0055] like Figure 6 In the embodiment, the position of each driving nozzle 56 on each wing conforms to the rotational overlap structure of 180° rotation. That is, the distance A1 between each driving nozzle 56 and the end of the wing is equal, and the vertical distance B1 between each driving nozzle 56 and the top end of the wing is also equal.

[0056] like Figure 7 In the embodiment, each driving nozzle 56 is arranged to protrude from the vertical side surface of the side wing of the spray body 51, and the length of the vertical side surface of each driving nozzle 56 protruding from the opposite end thereof is equal; the specification and size of each driving nozzle 56 itself are also the same (ie, Figure 5 The outer dimensions of the two driving nozzles 56 are marked as C1 and C2, C1=C2).

[0057] like Figure 8 In the figure, the positional characteristics of each exhaust hole 57 on each wing also conform to the rotational overlap structure rotated by 180° (G1=G2, H1=H2).

[0058] When the food processing machine is in the spray cleaning state, the rotary cleaning device 5 uses the water pump 32 to deliver water of a certain pressure from the water tank 31 through the water pipe 33 from the water inlet joint 53 into the waterway 52, so that the rotary cleaning device 5 rotates automatically. During the automatic rotation process, the nozzle 56 is driven to spray a water column toward the upper end of the inner wall of the food container 21 so that the upper end of the food container 21 can be cleaned, and the upper nozzle 55 sprays a water column toward the inner wall of the container cover 4 so that the inner wall of the container cover 4 can be cleaned. The cleaning is thorough and a better use experience can be obtained.

[0059] 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.
