Description

Technical Field

[0001] This application relates to the field of kitchen appliance technology, and more particularly to a food processing machine. Background Technology

[0002] During the use of existing food processing machines (such as soy milk makers, blenders, and pulverizers), the internal temperature of the motor will rise over time. The poor heat dissipation performance of the motor in existing food processing machines leads to malfunctions of circuit boards and electronic components, resulting in unstable product performance.

[0003] To address the aforementioned issues, prior art CN201710720155.6 discloses a blender, which includes upper and lower motor covers housing a motor assembly. The lower motor cover has a left air duct cover, a right air duct cover, a left air duct groove, and a right air duct groove on its side. The left air duct cover and the left air duct groove define a left air duct, and the right air duct cover and the right air duct groove define a right air duct. Simultaneously, the upper motor cover has a left air inlet hood connecting to the left air duct and a right air inlet hood connecting to the right air duct. Air enters the left and right air ducts through the left and right air inlet hoods and then enters the motor assembly for heat dissipation, subsequently flowing out through the air outlet on the base, thus achieving the purpose of cooling the motor assembly. However, the arrangement of the components in the above structure is not compact, and the left and right air duct covers, left air duct groove, and right air duct groove occupy the lateral space inside the blender casing, resulting in a large overall size of the blender. Utility Model Content

[0004] This application provides a food processing machine to solve the problem of non-compact component installation layout and large overall size of existing food processing machines.

[0005] This application provides a food processing machine, including a housing and a cup. A motor is installed inside the housing, and the output shaft driven by the motor is connected to a crushing device inside the cup. An air guide shroud with an opening at the lower end is installed on the outer side of the motor. A support plate that closes the opening is horizontally placed at the lower end of the air guide shroud. The air guide shroud and the top surface of the support plate form a receiving cavity for accommodating the motor. A cover plate is also installed on the top surface of the support plate. The cover plate and the support plate form an air duct. The cover plate cooperates with the air guide shroud so that one end of the air duct communicates with the receiving cavity, and the other end communicates with an air vent provided on the housing.

[0006] Compared with the prior art, this application has a horizontally placed support plate at the lower end of the air guide shroud, forming a cavity for accommodating the motor between the support plate and the support plate. At the same time, a cover plate is installed on the top surface of the support plate, and an air duct is formed between the support plate and the cover plate to connect the cavity. The air duct is used to dissipate heat from the motor in the cavity. Moreover, the air guide shroud is located above the support plate, and the cover plate is placed on the top surface of the support plate, so that the air guide shroud, the cover plate and the support plate are connected as a whole. This makes the installation layout of the three more compact and does not occupy the lateral space inside the housing, resulting in a smaller overall size of the food processing machine.

[0007] As a preferred technical solution, the side wall of the air guide shroud is provided with an avoidance opening, one end of the cover plate extends into the receiving cavity through the avoidance opening, and the avoidance opening is held in place on the outside of the cover plate.

[0008] The cover plate extends into the receiving cavity through the clearance opening of the air guide shroud. On the one hand, this allows the air duct formed by the cover plate and the support plate to connect with the inside of the receiving cavity. On the other hand, the clearance opening can limit the position of the cover plate to improve the installation stability of the cover plate.

[0009] As a preferred technical solution, the side wall of the air guide hood is provided with a communication port, and the end face of the cover plate abuts against the side wall of the air guide hood at the edge of the communication port, so that the air duct communicates with the receiving cavity through the communication port.

[0010] A connecting port is provided on the side wall of the air guide shroud. The air duct formed by the cover plate and the support plate can be connected to the receiving cavity through the connecting port to realize the circulation of gas inside the receiving cavity, so as to achieve the purpose of heat dissipation of the motor.

[0011] As a preferred technical solution, the motor includes a motor housing located within the receiving cavity, and the motor housing is provided with a heat dissipation vent, which is disposed opposite to one end of the air duct.

[0012] By setting heat dissipation vents on the motor housing, with one end of the vents facing the air duct, outside air can directly enter the motor housing through the vents when it flows into the housing cavity through the air duct, thus dissipating heat from the components inside the motor housing and further improving the heat dissipation effect of the motor.

[0013] As a preferred technical solution, one end of the cover plate extends through the air guide shroud into the receiving cavity and abuts against the outer wall of the motor housing at the edge of the heat dissipation port.

[0014] Place one end of the cover plate against the heat dissipation vent, so that one end of the air duct can cover the heat dissipation vent, ensuring that more air enters the motor housing to improve the heat dissipation effect.

[0015] As a preferred technical solution, the cover plate includes a separate first cover plate and a second cover plate, the air duct includes an air inlet duct formed by the first cover plate and the support plate and an air outlet duct formed by the second cover plate and the support plate, the air vents provided on the housing include an air inlet and an air outlet, the air inlet duct is connected to the outside through the air inlet, and the air outlet duct is connected to the outside through the air outlet.

[0016] The first cover plate and the support plate form an air intake duct to allow air to enter, and the second cover plate and the support plate form an air outlet duct to allow the dissipated air to flow out, thus achieving the purpose of air circulation. Moreover, the first cover plate and the second cover plate are set separately, which is conducive to the installation of both of them with the support plate.

[0017] As a preferred technical solution, the air duct includes a first air duct and a second air duct, and the cover plate includes an integrally formed first cover portion and a second cover portion. The first air duct is formed by the first cover portion and the support plate, and the second air duct is formed by the second cover portion and the support plate. The support plate is provided with a first ventilation hole and a second ventilation hole that are connected to the air outlet. The first air duct is connected to the air outlet through the first ventilation hole, and the second air duct is connected to the air outlet through the second ventilation hole.

[0018] The first and second cover portions, which are integrally formed, form the first and second air ducts with the support plate, respectively, thereby forming an airflow path. Moreover, the integrally formed first and second cover portions also facilitate the processing and manufacturing of the cover plate.

[0019] As a preferred technical solution, the support plate is provided with a water collection groove located between the first ventilation hole and the second ventilation hole, and the cover plate is provided with a hollow part to avoid the water collection groove, and the first cover part and the second cover part are arranged around the hollow part.

[0020] As a preferred technical solution, the food processing machine further includes a power board, which is mounted on the lower surface of the support plate.

[0021] Mounting the power board on the lower surface of the bracket plate makes good use of the bottom space of the bracket plate. On the other hand, it also ensures that the power board is located below the bracket plate, so the air after heat dissipation will not pass through the power board and will not condense on the power board, thus preventing damage to the power board.

[0022] As a preferred technical solution, the support plate is fixed to the lower end of the air guide shroud by fasteners;

[0023] Alternatively, the support plate may be provided with a positioning structure, and the air guide shroud may be positioned and installed on the positioning structure so as to be supported by the support plate.

[0024] As a preferred technical solution, the housing includes a cup body outer shell fitted onto the outside of the cup body and a bottom cover disposed at the bottom of the cup body outer shell;

[0025] Alternatively, the cup body is a glass cup body, the shell is fitted onto the lower part of the glass cup body, and the upper part of the glass cup body is exposed;

[0026] Alternatively, the food processing machine includes a base, the cup body is detachably mounted on the base, and the housing is formed as the outer wall of the base. Attached Figure Description

Detailed Implementation

[0039] To better understand the above-mentioned objectives, features, and advantages of this application, the solution of this application will be further described below. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0040] Many specific details are set forth in the following description in order to provide a full understanding of this application, but this application may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only some embodiments of this application, and not all embodiments.

[0041] Considering the problem that existing food processing machines, after adding a heat dissipation structure for the motor, have an insufficiently compact internal component layout, resulting in a large overall size, this application provides a food processing machine, such as... Figures 1-4 As shown, where Figure 1 This is a schematic diagram of the structure of a food processing machine according to an embodiment of this application; Figure 2 This is a schematic diagram showing the structure of a food processing machine with an air inlet according to an embodiment of this application; Figure 3 This is a schematic diagram of the structure of a food processing machine with an air outlet, according to an embodiment of this application. Figure 4 This embodiment of the food processor shows an exploded structural diagram of a wind deflector 5, a support plate 6, a cover plate, and a housing 1. The food processor includes a housing 1 and a cup body 2. Depending on the overall shape of the food processor, the housing 1 may include a cup body outer shell 11 fitted over the outside of the cup body 2 and a bottom cover 12 disposed at the bottom of the cup body outer shell 11. In this case, the cup body 2 is located inside the housing 1 (e.g., ...). Figure 1(As shown). The housing 1 can also be fitted onto the lower part of the cup body 2. In this case, the cup body 2 can be a glass cup, with the upper part of the glass cup exposed. The housing 1 can also be the outer wall of the machine base. In this case, the food processing machine has a split structure, and its cup body 2 can be detachably installed on the machine base, with the housing 1 being the outer wall of the machine base. In this embodiment, the housing 1 includes the outer shell 11 of the cup body and the bottom cover 12 as an example.

[0042] A motor 3 is installed inside the housing 1. The output of the motor 3 drives a pulverizing device 4 connected inside the cup body 2. For example, the motor 3 may be connected to an output shaft, which is connected to the pulverizing device 4, so that the motor 3 drives the pulverizing device 4 to rotate through the output shaft. In this embodiment, the motor 3 is preferably a brushless motor, and more preferably a variable frequency brushless motor.

[0043] An air guide shroud 5 with an open lower end is installed on the outer side of the motor 3. A support plate 6 with a closed opening is horizontally placed at the lower end of the air guide shroud 5. The top surface of the support plate 6 and the air guide shroud 5 enclose a receiving cavity, in which the motor 3 is located. In addition, a cover plate is installed on the top surface of the support plate 6. The cover plate can form an air duct with the support plate 6. With the cooperation of the cover plate and the air guide shroud 5, one end of the air duct is connected to the receiving cavity, and the other end is connected to the air outlet of the housing 1. Outside air can enter the air duct through the air outlet of the housing 1 and flow to the receiving cavity to dissipate heat from the motor 3 inside the receiving cavity.

[0044] Compared with the prior art, this embodiment of the application achieves heat dissipation for the motor 3. The air guide shroud 5 is located above the support plate 6, and the cover plate is placed on the top surface of the support plate 6, so that the air guide shroud 5, the cover plate and the support plate 6 are connected as a whole. This makes the installation layout of the three more compact and does not occupy the lateral space inside the housing 1, making the overall size of the food processing machine smaller.

[0045] In this embodiment, it should be noted that the air vent on the housing 1 can be either an air inlet 13 or an air outlet 14. Correspondingly, the air duct formed by the cover plate and the support plate 6 can be either an air inlet duct or an air outlet duct. This achieves heat dissipation for the motor 3 while improving the compactness of the installation layout.

[0046] Figure 5 This is a schematic diagram of the assembly structure of the air guide shroud 5, support plate 6, and cover plate of the food processing machine according to an embodiment of this application; Figure 6 This is an exploded structural diagram showing the assembly of the air guide shroud 5, support plate 6, and cover plate of the food processing machine according to an embodiment of this application. Figure 5 and Figure 6As shown, the cover plate in this embodiment of the application has a split structure, comprising a first cover plate 71 and a second cover plate 72. The first cover plate 71 and the support plate 6 enclose an air inlet duct, and the second cover plate 72 and the support plate 6 enclose an air outlet duct. The corresponding housing 1 is provided with an air inlet 13 and an air outlet 14. The air inlet duct communicates with the outside through the air inlet 13, and the air outlet duct communicates with the outside through the air outlet 14. That is to say, the cover plate and the support plate 6 of this application simultaneously form an air inlet duct and an air outlet duct to achieve air intake into the receiving cavity and air exhaust from the receiving cavity.

[0047] In this embodiment, by setting the cover plate as a separate first cover plate 71 and second cover plate 72, it is beneficial to manufacture the first cover plate 71 and second cover plate 72 and to install the first cover plate 71, second cover plate 72 and bracket plate 6.

[0048] It is understandable that the cover plate in this embodiment can also be an integral structure. In this case, the cover plate and the support plate 6 form two air ducts to realize air intake and air exhaust.

[0049] Preferably, the first cover plate 71 and the second cover plate 72 are installed in a vertical position so that the air inlet duct and the air outlet duct are distributed at 90°.

[0050] In this embodiment, a clearance opening 51 is provided on the side wall of the air guide shroud 5. This clearance opening 51 is used to avoid one end of the cover plate, so that one end of the cover plate can extend into the receiving cavity through the clearance opening 51. The cover plate extends into the receiving cavity through the clearance opening 51 of the air guide shroud 5. On the one hand, this allows the air duct formed by the cover plate and the support plate 6 to connect with the inside of the receiving cavity; on the other hand, the clearance opening 51 can limit the position of the cover plate, thereby improving the installation stability of the cover plate. This embodiment can be as follows... Figure 6 As shown, an avoidance opening 51 is provided on each of the two side walls of the air guide shroud 5. One of the avoidance openings 51 is used to avoid the first cover plate 71, and the other avoidance opening 51 is used to avoid the second cover plate 72.

[0051] In this application, in addition to the above-mentioned method of extending one end of the cover plate into the receiving cavity to achieve communication between the air duct and the receiving cavity, in another embodiment, a communication port (not shown in the figure) can be provided on the side wall of the air guide shroud 5. The end face of the cover plate abuts against the side wall of the air guide shroud 5 at the edge of the communication port, so that the air duct communicates with the receiving cavity through the communication port. In this embodiment, the cover plate does not need to extend into the receiving cavity, but directly communicates with the receiving cavity through the communication port on the air guide shroud 5.

[0052] In this embodiment, the cover plate and the support plate 6 are connected by a snap-fit ​​structure 711. For example, it can be as follows: Figure 6As shown, a buckle 711 is provided on the first cover plate 71, and a corresponding snap-fit ​​hole 61 is provided on the support plate 6. The first cover plate 71 and the support plate 6 are snapped together by the buckle 711 snapping into the snap-fit ​​hole 61. The connection between the second cover plate 72 and the support plate 6 can also be achieved by snapping.

[0053] Furthermore, one can refer to Figure 6 An upwardly extending protruding edge 712 can be provided on the top surface of the first cover plate 71, and a positioning protrusion 713 is provided on one side of the protruding edge 712. The aforementioned air guide shroud 5 can be embedded in the gap between the protruding edge 712 and the positioning protrusion 713, and is positioned by the protruding edge 712 and the positioning protrusion 713. This structure makes the connection between the first cover plate 71, the air guide shroud 5, and the support plate 6 tighter, and the resulting assembly structure is more compact. It should be noted that the installation method of the second cover plate 72 in this embodiment can be the same as that of the first cover plate 71.

[0054] In this embodiment, the support plate 6 is fixed to the lower end of the air guide shroud 5 by fasteners, such as... Figure 6 As shown, the air guide shroud 5 is provided with screw posts 51, and the bracket plate 6 is provided with through holes 62. Fasteners (which can be screws) pass through the through holes 62 and are fixed to the screw posts 51 to fix the air guide shroud 5 and the bracket plate 6.

[0055] In another embodiment, the air guide shroud 5 can also be supported by the bracket plate 6. In this case, the air guide shroud 5 can be positioned above the bracket plate 6 using a positioning installation method. For example, a positioning structure can be provided on the bracket plate 6, and the air guide shroud 5 can be positioned and installed on the positioning structure to achieve support by the bracket plate 6. The positioning structure can be a positioning slot installed on the bracket plate 6, with the lower end of the air guide shroud 5 embedded in the positioning slot to fix the air guide shroud 5 on the bracket plate 6.

[0056] By using the two installation methods described above, the air guide cover 5 and the bracket plate 6 can be integrated into a whole. When combined with the installation of the cover plate and the bracket plate 6, the three components form a whole, achieving a more compact structural layout and a smaller overall size.

[0057] In this embodiment, the air duct includes a first air duct and a second air duct. The cover plate includes an integrally formed first cover portion a and a second cover portion b. The first air duct is formed by the first cover portion a and the support plate 6, and the second air duct is formed by the second cover portion b and the support plate 6. The support plate 6 is provided with a first ventilation hole 63 and a second ventilation hole 64 that connect with the air outlet. The first air duct is connected to the air outlet through the first ventilation hole 63, and the second air duct is connected to the air outlet through the second ventilation hole 64. The integrally formed first cover portion a and the second cover portion b, together with the support plate 6, form the first air duct and the second air duct, respectively, thereby forming an airflow path. Moreover, the integrally formed first cover portion a and the second cover portion b also facilitate the processing and manufacturing of the cover plate.

[0058] It should be noted that both the first and second air ducts can be used for air intake, in which case the cover plate is the aforementioned first cover plate 71, with the first cover portion a and the second cover portion b formed on the first cover plate 71. Alternatively, both the first and second air ducts can be used for air exhaust, in which case the cover plate is the aforementioned second cover plate 72, with the first cover portion a and the second cover portion b formed on the second cover plate 72. Furthermore, the first and second air ducts can also be used interchangeably, with one for air intake and the other for air exhaust; in this case, the cover plate integrates the functions of both the first cover plate 71 and the second cover plate 72.

[0059] In this embodiment, the first cover portion a and the second cover portion b are formed on the first cover plate 71, and the first cover plate 71 forms the first air duct and the second air duct, as an example. Figure 6 and Figure 7 As shown, the first cover plate 71 includes a first cover portion a and a second cover portion b, which are arranged left and right.

[0060] In addition, such as Figure 6 As shown, in this embodiment, the support plate 6 is provided with a water collection trough 65 located between the first ventilation hole 63 and the second ventilation hole 64. The cover plate (i.e., the first cover plate 71) is provided with a hollow portion 714 to avoid the water collection trough 65. The first cover portion a and the second cover portion b are arranged around the hollow portion 714. That is, by providing the hollow portion 714, the water collection trough 65 can be avoided when the cover plate is installed on the support plate 6.

[0061] Preferably, a water guide column 66 communicating with a water collection tank 65 is provided at the bottom of the support plate 6. The water guide column 66 extends into the air vent, allowing water to flow out through the air vent via the water guide column 66 and the water collection tank 65. The air vent can be an air inlet 13 or an air outlet 14 on the bottom cover 12. In this embodiment, the air vent is... Figure 6 The air inlet 13 is shown.

[0062] In this embodiment, as Figure 8As shown, an air inlet 13 and an air outlet 14 are provided on the bottom cover 12 of the housing 1. The air inlet 13 is provided with an insertion hole 131, into which the water guide column 66 can be inserted.

[0063] Furthermore, in this embodiment, the inner side of the bottom cover 12 is provided with an upwardly raised portion 121, and the inner side of the raised portion 121 is provided with a through ventilation channel. The lower end of the ventilation channel forms an air vent, and the upper end of the ventilation channel is connected to the air duct. Through the above structure, the ventilation channel is provided with a certain height, which can effectively prevent water stains or dust from entering the air duct and the housing cavity with the outside air, and avoid damage to the motor 3.

[0064] It should be noted that the raised portion 121 in this embodiment can also be provided as two, with the lower end of one forming an air inlet 13 and the lower end of the other forming an air outlet 14.

[0065] Preferably, in this embodiment, as Figure 3 As shown, the food processing machine also includes a power board 8, which is installed on the lower surface of the support plate 6. On the one hand, it makes reasonable use of the bottom space of the support plate 6 to achieve a compact layout of the overall structure. On the other hand, it also makes the power board 8 located below the support plate 6, so that the air after heat dissipation will not pass through the power board 8 and will not condense on the power board 8, thus preventing damage to the power board 8.

[0066] In this embodiment, as Figure 2 and Figure 3 As shown, the motor 3 includes a motor housing located within a receiving cavity. A heat dissipation vent (not shown in the figure) is provided on the motor housing, and this vent is positioned opposite one end of the air duct. Because the heat dissipation vent is positioned opposite one end of the air duct, outside air flowing into the receiving cavity through the air duct can directly enter the motor housing through the heat dissipation vent, dissipating heat from the components inside the motor housing and further improving the heat dissipation effect on the motor 3.

[0067] Preferably, one end of the cover plate extends through the air guide shroud 5 into the receiving cavity and abuts against the outer wall of the motor housing at the edge of the heat dissipation vent. By abutting one end of the cover plate against the heat dissipation vent, one end of the air duct can cover the heat dissipation vent, ensuring more air enters the motor housing and improving heat dissipation. It should be noted that in this embodiment, when one end of the cover plate abuts against the heat dissipation vent, the aforementioned air duct connects to the receiving cavity. This can mean that the air duct connects to the space inside the motor housing located within the receiving cavity through the heat dissipation vent, or that part of the air duct connects to the receiving cavity and the other part connects to the heat dissipation vent.

[0068] It should be noted that the food processing machine in this application can be a soymilk maker, or a blender, pulverizer, or other electrical appliance.

[0069] It should be noted that, in this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0070] The above description is merely a specific embodiment of this application, enabling those skilled in the art to understand or implement this application. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of this application. Therefore, this application is not to be limited to the embodiments described herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
