Description

Technical Field

[0001] The utility model relates to kitchen appliances, and in particular to a food processor. Background Art

[0002] In the existing food processor with a motor disposed at the bottom of the cup body and directly driving a crushing device by a motor shaft, the motor is usually fixed below the cup body, and the power board is installed on one side of the motor and vertically arranged. For example, Patent CN201520523722.5 discloses a food processor. In this solution, the motor is installed below the cup body, and the power board is located on one side of the motor and vertically arranged. Since the dimensions of the motor and the power board in the axial direction are relatively long, such installation will make the bottom volume of the food processor relatively large and the height relatively high, resulting in a relatively large overall size of the food processor and an upward shift of the center of gravity of the food processor. During operation, the food processor is prone to obvious shaking or even tipping. To solve the above problems, Patent 202011039397.7 discloses a food processor. In this solution, an installation slot for the motor to pass through is provided on the power board, so that the power board is installed around the outside of the motor through the installation slot. This solution saves the cavity space for installing the motor and the power board to a certain extent. After the power board is horizontally arranged, the bottom volume of the food processor can be reduced to achieve a reduction in the height and center of gravity of the whole food processor. However, since an installation slot is provided on the power board in this solution, the overall effective use area of the power board is reduced, resulting in a reduction in the number of functional modules on the power board, and additional functional modules need to be provided to meet the multi-functional operation of the food processor. Summary of the Utility Model

[0003] The utility model provides a food processor to solve the problem that a food processor with a motor directly driven at the lower part cannot take into account the reliable layout of components on the power board and the compact installation of the motor and the power board.

[0004] To achieve the above object, the utility model adopts the following technical scheme: A food processor, comprising a housing, a cup body having a crushing cavity, a motor and a power board disposed below the cup body inside the housing, the motor being electrically connected to the power board, a rotating shaft driven by the motor penetrating the cup body and extending into the crushing cavity, and a crushing device installed at the end of the rotating shaft in the crushing cavity, characterized in that: the motor is a brushless motor, the motor includes a motor main body sleeved outside the rotating shaft, the outer diameter of the motor main body is greater than the height of the motor main body, a smart power module for controlling the motor is provided on the power board, an isolation seat for isolating the motor from the power board is provided below the motor, and the power board is horizontally hoisted on the isolation seat.

[0005] Since the intelligent power module is set on the power supply board to control the brushless motor, during operation, the intelligent power module will generate a lot of heat, and the motor operation will also generate a lot of heat. Although the isolation seat can, to a certain extent, isolate the heat of the motor from spreading to the power supply board, after the heat of the motor is transferred to the isolation board, the temperature of the isolation board rises after being heated, which will affect the heat dissipation effect of the power supply board and easily cause the temperature of the intelligent power module to be too high to work properly.

[0006] Therefore, the present utility model further adopts the following scheme. The isolation seat includes a first isolation board and a second isolation board which are separately arranged. The second isolation board is fixed to the bottom of the first isolation board. The first isolation board is located below the motor, and the power supply board is fixed to the bottom of the second isolation board. There is an unclosed heat insulation gap between the first isolation board and the second isolation board.

[0007] Further, the first isolation board is provided with a motor accommodation cavity for accommodating the motor. A fan is arranged in the motor accommodation cavity. An opening is arranged on the cavity wall of the motor accommodation cavity. The motor accommodation cavity communicates with the heat insulation gap through the opening.

[0008] Further, the first isolation board is provided with an upwardly protruding annular border. The annular border encloses to form the motor accommodation cavity. The opening is arranged on the annular border. The top of the annular border is provided with a top board protruding radially outward. The top board is provided with a downwardly protruding baffle. The baffle is located outside the opening. The top board, the annular border and the baffle jointly enclose to form an air duct. The air duct communicates with the motor accommodation cavity through the opening, and the bottom opening of the air duct communicates with the heat insulation gap.

[0009] Further, one of the first isolation board and the second isolation board is provided with a convex column, and the other is provided with a limit hole for the convex column to insert. The convex column is used to separate the first isolation board and the second isolation board to form a heat insulation gap, and the convex column and the limit hole cooperate to position the first isolation board and the second isolation board; or, one of the first isolation board and the second isolation board is provided with a limit rib, and the other is provided with a limit groove for the limit rib to insert. The limit rib is used to separate the first isolation board and the second isolation board to form a heat insulation gap, and the limit rib and the limit groove cooperate to position the first isolation board and the second isolation board; or, a protrusion is arranged between the first isolation board and the second isolation board. The first isolation board and the second isolation board are fixedly connected through the protrusion. The protrusion separates the first isolation board and the second isolation board to form a heat insulation gap.

[0010] Further, the isolation seat forms a motor accommodation cavity for accommodating the motor. An opening communicating with the inner cavity of the housing is arranged on the side wall of the motor accommodation cavity. A fan is connected to the lower end of the rotating shaft in the motor main body. A ventilation hole is arranged on the side wall of the motor main body. The ventilation hole is arranged opposite to the opening.

[0011] Further, positioning posts are provided at the bottom of the cup body, and a first mounting portion corresponding to the positioning posts is provided on the motor main body. The motor main body is fixedly connected to the positioning posts through the first mounting portion so that the motor main body is hoisted at the bottom of the cup body. A second mounting portion is further provided on the motor main body, and a positioning portion is correspondingly provided on the isolation seat. The isolation seat is fixedly connected to the second mounting portion through the positioning portion.

[0012] Further, positioning posts are provided at the bottom of the cup body, a first assembly portion is correspondingly provided on the motor main body, a second assembly portion is provided on the isolation seat, and after the second assembly portion holds the first assembly portion, they are jointly fixed on the positioning posts.

[0013] Further, a power board accommodation cavity for accommodating the power board is formed in the isolation seat, and the power board is sealed with glue in the power board accommodation cavity.

[0014] Further, the intelligent power module is connected with U-phase, V-phase, and W-phase output lines. The ends of the U-phase, V-phase, and W-phase output lines are fixed in the first socket. The motor is connected with U-phase, V-phase, and W-phase input lines. The ends of the U-phase, V-phase, and W-phase input lines are fixed in the second socket. The motor is electrically connected to the power board by plugging and mating the first socket with the second socket.

[0015] After adopting the above technical solutions, the following beneficial technical effects are achieved:

[0016] 1. In the present utility model, the relatively slender brushed motor in the prior art is replaced with a brushless motor whose outer diameter is greater than its height. Compared with the existing slender brushed motor, after adopting the brushless motor in this solution, on the one hand, the radial dimension of the motor becomes larger and the axial dimension becomes smaller. In the case of limited installation space, compared with the brushed motor, there is a larger installation space below the brushless motor in this solution. By horizontally fixing the power board on the isolation seat below the motor, the installation space below the motor is fully utilized, making the installation of the motor and the power board more compact. Since the motor and the power board are flattened, the center of gravity of the whole machine moves downward, and when the machine is running, the whole machine is more stable and not easy to shake. On the other hand, the brushless motor does not have carbon brushes, so no carbon powder is generated during the operation of the motor, and there is no need to additionally set a protective structure for protecting the power board. The noise generated by the brushless motor is relatively low, and the speed and steering can be smoothly changed through the brushless motor to meet the diverse processing requirements of food ingredients; at the same time, in the present utility model, the power board is horizontally placed below the motor, and there is no need to set an installation slot for the motor to pass through on the power board, making the power board structure complete and ensuring the reliable layout of the components on the power board; in addition, an isolation seat is provided between the motor and the power board, and the isolation seat can separate the motor and the power board to prevent the heat generated by the operation of the motor from diffusing to the power board, avoiding overheating and damage of the intelligent power module on the power board and thus unable to operate normally.

[0017] 2. In the present utility model, by setting the isolation base as a first isolation plate and a second isolation plate which are separately arranged, the power supply board is arranged on the second isolation plate, and a non-closed heat insulation gap is arranged between the first isolation plate and the second isolation plate. At this time, three layers of intervals are formed between the motor and the power supply board. After the heat generated by the motor operation is transferred to the first isolation plate, the air in the heat insulation gap will cool the first isolation plate. After the air in the heat insulation gap is heated, it will diffuse to the external air and the second isolation plate at the same time. At this time, the heat diffused to the second isolation plate is relatively low, which can more effectively avoid the diffusion of the motor heat to the power supply board.

[0018] 3. In the present utility model, a motor accommodation cavity is formed in the first isolation plate, a fan is arranged in the motor accommodation cavity, an opening is arranged on the wall of the motor accommodation cavity, and the rotation of the fan enables the air flow to flow through the opening in the heat insulation gap, thereby accelerating the air flow in the heat insulation gap. On the one hand, it can more effectively cool the first isolation plate. On the other hand, the flowing air flow will also cool the second isolation plate through cooling, further improving the heat dissipation effect of the power supply board.

[0019] 4. In the present utility model, the motor accommodation cavity is communicated with the heat insulation gap through an air duct, and the baffles and the top plate forming the air duct will have an aggregating effect on the air flow, further improving the air flow rate, so that the cooling effect of the air flow on the first isolation plate and the second isolation plate is better.

[0020] 5. In the present utility model, a convex column is arranged on one of the first isolation plate and the second isolation plate, and a limit hole is arranged on the other one. While separating the first isolation plate and the second isolation plate, the insertion of the convex column into the limit hole can realize the positioning of the first isolation plate and the second isolation plate. While achieving effective heat insulation, the parts required for installation and positioning are saved, and the installation cost is saved.

[0021] 6. In the present utility model, the protrusion used for isolating the first isolation plate and the second isolation plate is simultaneously used as the component connecting the first isolation plate and the second isolation plate, which can save the parts required for installation while achieving effective heat insulation, and save the installation cost.

[0022] 7. In the present utility model, a motor accommodation cavity is arranged in the isolation base, a fan is arranged in the motor main body, ventilation holes are arranged on the side wall of the motor main body, and an opening opposite to the ventilation holes is arranged on the side wall of the motor accommodation cavity. Through the rotation of the fan, the heat generated by the motor is timely diffused to the outside, ensuring the effective heat dissipation of the motor.

[0023] 8. In the present utility model, a power supply board accommodation cavity is arranged in the isolation base, and the power supply board is sealed with glue in the power supply board accommodation cavity. Since the power supply board is located below the motor and is closer to the bottom of the food processor, by sealing the power supply board with glue, it is avoided that when the user cleans the food processor, the water flow enters the food processor from the bottom, resulting in the contact of the power supply board components with water and causing a short circuit, affecting the normal operation of the food processor.

[0024] 9. In the present utility model, a first socket is provided at the other end of the three-phase output line connected to the intelligent power module, and a second socket is connected to the other end of the three-phase input line connected to the motor. The motor is electrically connected to the intelligent power module through the insertion and cooperation of the two sockets. The cooperation of the sockets can directly connect the three-phase lines, improving the installation efficiency of the components. Description of the Drawings

A stator assembly and a rotor assembly are arranged in the motor body 6, and the rotating shaft 8 runs through the center of the rotor assembly. A fan 7 is connected to the bottom of the rotating shaft 8, and the fan 7 is located inside the motor body 6. The top of the rotating shaft 8 extends from the top of the motor body 6, and a threaded hole is arranged at the top of the rotating shaft 8. A ventilation hole 62 is also arranged on the side wall of the motor body 6, and the motor is also connected to a U-phase input line 63, a V-phase input line 64, and a W-phase input line 65, respectively. The other ends of the three-phase input lines are respectively connected to sub-ends, and each sub-end is fixed in the second socket 66.

[0035] A rotating shaft 8 driven by a motor extends from the bottom of the cup body 2 into the grinding chamber. A grinding device 5 is also provided in the grinding chamber. A threaded column is provided at the bottom of the grinding device 5. The grinding device is threadedly connected to the threaded hole at the top of the rotating shaft 8 through the threaded column.

[0036] A first isolation plate 9 is arranged below the motor. The first isolation plate 9 is provided with an upwardly protruding annular rim 98 in the circumferential direction. The annular rim 98 and the top wall of the first isolation plate 9 are enclosed together to form a motor accommodating chamber 93 for accommodating the motor. The side wall of the motor accommodating chamber, that is, the annular rim 98 is provided with an opening 94. A top plate 96 protruding radially outward is arranged on the top of the annular rim 98. The top plate 96 is arranged around the motor accommodating chamber. The top plate 96 is provided with four second assembly parts 92. The second assembly part 92 is an annular convex column penetrating the center. The inner wall of the annular convex column is provided with a step. The center of the step is provided with a through hole. The outer circumference of the top plate 96 is provided with a downwardly protruding convex column 91. The bottom of the convex column 91 is provided with a threaded hole. The top plate 96 is also provided with a downwardly protruding baffle 97. The baffle is located outside the opening 94. The top plate 96, the baffle 97, and the outer wall of the annular rim 98 are enclosed to form an air duct. One end of the air duct is the opening 94, and the other end of the air duct is the bottom opening 95 of the air duct.

[0037] A second isolation plate 10 is arranged below the first isolation plate 9, and a peripheral edge extending downward is arranged circumferentially on the second isolation plate 10, so that the second isolation plate 10 and the peripheral edge are combined to form a box body with an opening at the lower end, and a power board accommodating cavity for accommodating the power board 11 is formed in the box body. The power board 11 is sealed in the power board accommodating cavity with glue poured downward from the front side, and a limiting hole 101 with an opening at the upper end is arranged on the outer periphery of the second isolation plate 10, and the limiting hole 101 is a cylindrical groove, and the bottom wall of the cylindrical groove is provided with an opening, and the depth of the cylindrical groove is less than the length of the protruding column.

[0038] The power supply board 11 is provided with an intelligent power module, and the intelligent power module is respectively connected with a U-phase output line 112, a V-phase output line 113 and a W-phase output line 111. The other ends of the three-phase output lines are respectively connected with female terminals, and each female terminal is fixed in the first socket 114.

[0039] During installation, the first assembly part 61 of the motor main body 6 and the second assembly part 92 of the first isolation plate 9 are sequentially sleeved on the positioning column 14 at the bottom of the cup body 2. The first assembly part 61 is pressed against the step of the positioning column 14 through a shock absorber, and the first isolation plate 9 is pressed against the shock absorber through the top wall of the second assembly part 92. The threaded hole of the positioning column, the through hole of the shock absorber, and the through hole of the annular convex column correspond in sequence. The screw sequentially passes through the through hole of the annular convex column and the through hole of the shock absorber and is threadedly connected with the threaded hole of the positioning column, so that the motor main body and the first isolation plate are jointly hoisted at the bottom of the cup body, and the ventilation hole 62 of the motor main body is disposed opposite to the opening 94 of the motor accommodation cavity wall.

[0040] Subsequently, the convex column 91 of the first isolation plate 9 is correspondingly inserted into the limiting hole 101 of the second isolation plate 10. The bottom of the convex column 91 abuts against the bottom wall of the cylindrical groove. The threaded hole at the bottom of the convex column 91 corresponds to the opening at the bottom wall of the cylindrical groove. The screw passes through the opening and is threadedly connected with the threaded hole at the bottom of the convex column 91 to fix the second isolation plate 10 to the bottom of the first isolation plate 9. Due to the separation of the convex column 91, a heat insulation gap 13 is formed between the first isolation plate 9 and the second isolation plate 10. The motor accommodation cavity is communicated with the heat insulation gap through the air duct. The first socket 114 is plugged into the second socket 66 to connect the motor with the intelligent power module of the power supply board.

[0041] The housing 1 includes a shell and a base that penetrate up and down. After being installed according to the above steps, the combination of the cup body, the motor, and the power supply board is installed in the shell, and then the base is fixed below the power supply board.

[0042] After the food processor runs, the external power supply supplies power to the power supply board through the socket. The intelligent power module of the power supply board controls the rotation of the motor through the three-phase line, and the fan rotates accordingly. When the fan rotates counterclockwise, the air flow enters the motor accommodation cavity through the ventilation hole 62 of the motor main body 6, then enters the air duct from the opening 94, and finally enters the heat insulation gap from the open end 95 at the bottom of the air duct, and then flows into the inner cavity of the housing from the heat insulation gap.

[0043] In this embodiment, the relatively slender brushed motor in the prior art is replaced with a brushless motor whose outer diameter is larger than its height. Compared with the prior slender brushed motor, after adopting the brushless motor in this solution, on the one hand, the radial dimension of the motor becomes larger and the axial dimension becomes smaller. In the case of limited installation space, compared with the brushed motor, there is a larger installation space under the brushless motor of this solution. The first isolation plate and the second isolation plate are installed and fixed under the motor. By horizontally fixing the power board on the second isolation plate under the motor, the installation space under the motor is fully utilized, making the installation of the motor and the power board more compact. Since the motor and the power board are flattened, the center of gravity of the whole machine moves downward. When the machine is running, the whole machine is more stable and not easy to shake. On the other hand, the brushless motor does not have a carbon brush, so no carbon powder is generated during the operation of the motor, and there is no need to separately set a protection structure for protecting the power board. The noise generated by the brushless motor is also relatively low, and the change of the rotational speed and the steering can be smoothly achieved through the brushless motor, meeting the diverse processing requirements for food ingredients; at the same time, in the present utility model, the power board is horizontally placed under the motor, and there is no need to set an installation slot for the motor to pass through on the power board, making the structure of the power board complete and ensuring the reliable layout among the components on the power board.

[0044] At the same time, because after adopting the brushless motor, the power board needs to be provided with an intelligent power module for controlling the motor. During the working process, both the intelligent power module and the motor on the power board will generate a lot of heat. After horizontally fixing the power board under the motor, the heat of the motor will be transferred to the power board, affecting the heat dissipation effect of the power board. And there are a first isolation plate and a second isolation plate between the motor and the power board. The first isolation plate and the second isolation plate are separated by convex posts to form a heat insulation gap. The motor accommodation cavity on the first isolation plate is also communicated with the heat insulation gap through an air duct. After the fan rotates, the air flow passes through the air duct and flows into the heat insulation gap, making the air in the heat insulation gap in a flowing state. When the motor works, it diffuses heat to the first isolation plate. The flowing air flow can better cool the first isolation plate and the second isolation plate. On the one hand, it more effectively avoids the diffusion of the motor heat to the power board. On the other hand, it can cool the second isolation plate, thereby reducing the temperature of the power board and ensuring the heat dissipation effect of the power board. Through the aggregation effect of the baffle and the top plate of the air duct on the air flow, the flowing rate of the air flow can be further increased, achieving a better heat dissipation effect.

[0045] In this embodiment, the convex posts used to isolate the first isolation seat and the second isolation seat are simultaneously used as the components for connecting the first isolation seat to the second isolation seat, which can save the parts required for installation and the installation cost while achieving effective heat insulation.

[0046] In this embodiment, a power board receiving cavity is provided in the isolation base, and the power board is sealed with potting glue in the power board receiving cavity. Since the power board is located below the motor and closer to the bottom of the food processor, by sealing the power board with potting glue, it is avoided that when the user cleans the food processor, water flows into the food processor from the bottom, causing the components of the power board to come into contact with water and resulting in a short circuit, which affects the normal operation of the food processor.

[0047] In this embodiment, a first socket is provided at the other end of the three-phase output line connected to the intelligent power module, and a second socket is connected to the other end of the three-phase input line connected to the motor. The motor is electrically connected to the intelligent power module through the plug-in cooperation of the two sockets. Through the cooperation of the sockets, the three-phase lines can be directly connected, improving the installation efficiency of the components.

[0048] In the above embodiment, the convex column for isolating the first isolation plate and the second isolation plate can be a cylinder or a prism, and the corresponding limit hole can be set as a cylindrical groove or a prism-shaped groove. The convex column can also be provided on the second isolation plate, and the limit hole is correspondingly provided on the first isolation plate. Of course, it can also be that a limiting rib protruding downward is provided at the bottom of the first isolation plate, and a limiting groove is provided on the second isolation plate. The axial length of the limiting rib is greater than the depth of the limiting groove. The limiting rib is inserted into the limiting groove and abuts against the bottom wall of the limiting groove, thereby separating the first isolation plate and the second isolation plate to form a heat insulation gap. Similarly, the limiting rib can be provided on the second isolation plate, and the limiting groove is provided on the first isolation plate. It can also be that the first isolation plate is provided with a protruding portion protruding downward, and the protruding portion directly abuts against the second isolation plate to separate the two to form a heat insulation gap. Similarly, the protruding portion can also be provided on the second isolation plate, or protruding portions are provided on both the first isolation plate and the second isolation plate, and the two are separated by the mutual abutment of the protruding portions to form a heat insulation gap. The protruding portion can also be the aforementioned convex column. When the protruding portion is provided alone, the protruding portion can also be an arc-shaped protruding portion.

[0049] The direction of air flow can also be from the heat insulation gap into the motor receiving cavity. When the motor shaft rotates clockwise, the rotation of the fan will drive the air flow to flow from the heat insulation gap into the motor receiving cavity through the air duct, and the continuous flow of air in the heat insulation gap can also be realized. Of course, to realize the air flow, the air duct structure can also not be provided, and an opening is provided at the bottom wall of the motor receiving cavity to directly connect the motor receiving cavity and the heat insulation gap, and the air flow between the motor receiving cavity and the heat insulation gap can also be realized.

[0050] In another embodiment, a separate isolation base can also be provided between the motor and the power supply board. The bottom of the cup body is provided with positioning posts, the side wall of the positioning posts is provided with steps, and the bottom of the positioning posts is provided with threaded holes. The motor body is provided with a first mounting portion corresponding to the positioning posts. The first mounting portion can still be a ring that penetrates through the center. A shock-absorbing member is sleeved inside the ring, and a through hole is provided in the center of the shock-absorbing member. The motor body is further provided with a second mounting portion. The second mounting portion can be a limit post, and the bottom of the limit post is also provided with a threaded hole. An isolation base is provided below the motor body. The isolation base is provided with a positioning portion. The positioning portion can be an annular convex post that penetrates through the center. The inner wall of the annular convex post is provided with steps, and an opening is provided in the center of the steps. During installation, first, the first mounting portion is sleeved on the positioning post. The first mounting portion is pressed against the step of the positioning post through the shock-absorbing member. The through hole of the shock-absorbing member corresponds to the threaded hole of the positioning post. After the screw passes through the through hole, it is threadedly connected to the threaded hole of the positioning post to hoist the motor at the bottom of the cup body. Subsequently, the limit post of the motor body is inserted into the center of the annular convex post of the isolation base. The bottom of the limit post abuts against the step of the annular convex post. The opening of the annular convex post corresponds to the threaded hole of the limit post. After the screw passes through the opening of the annular convex post, it is threadedly connected to the threaded hole of the limit post to fix the isolation base to the bottom of the motor body. Of course, the isolation base can be provided without a limit post. The annular convex post of the isolation base is provided corresponding to the first mounting portion of the motor body. The first mounting portion and the annular convex post are sleeved on the positioning post in sequence. The annular convex post supports the first mounting portion. The opening of the annular convex post, the through hole of the shock-absorbing member, and the threaded hole of the positioning post correspond in sequence. After the screw passes through the opening of the annular convex post and the through hole of the shock-absorbing member, it is threadedly connected to the threaded hole of the positioning post to fix the motor body and the isolation base together on the positioning post. In this embodiment, a motor accommodation cavity can be provided on the side of the isolation base facing the motor. The wall of the motor accommodation cavity is provided with an opening. The side wall of the motor body is provided with a ventilation hole. The ventilation hole is arranged opposite to the opening. By the rotation of the fan, the heat generated by the motor is timely dissipated to the outside, ensuring the effective heat dissipation of the motor. Of course, a power supply board accommodation cavity can also be provided on the side of the isolation base facing the power supply board. The power supply board is sealed with glue in the power supply board accommodation cavity. Preferably, a motor accommodation cavity and a power supply board accommodation cavity can be provided on the isolation base at the same time.

[0051] In another embodiment, the first isolation plate and the second isolation plate can be tightly attached and installed. At this time, a double-layer heat insulation can be formed between the motor and the power supply board through the two isolation plates, which can effectively prevent the heat of the motor from diffusing to the power supply board. The second isolation plate can also be integrally formed below the first isolation plate.

[0052] Of course, the aforementioned outer shell can also be provided below the cup body, and the top of the outer shell is fixedly connected to the bottom of the cup body; in other embodiments, the food processor can also be a hand-free soymilk maker. The outer shell has a frame structure. The unmanned soymilk maker further includes a water tank provided on one side of the outer shell and a slurry receiving cup placed on the bottom plate of the outer shell. A motor and a power supply board are provided inside the outer shell. The motor and the power supply board can adopt the aforementioned installation method.

[0053] Of course, the aforementioned cup body can be a transparent cup body made of glass material, or an opaque cup body made of stainless steel material.

[0054] It can be understood that the solutions of the above-mentioned embodiments in the present utility model are not independent and can be combined with each other.
