Description

Technical Field

[0001] The utility model belongs to the technical field of food processing devices, and in particular relates to a waterproof food processing machine. Background Art

[0002] Existing food processing machines, such as wall-breaking machines with a detachable and washable cup body, generally have a detachable connection between the grinding cup and the motor assembly via a connector. During the operation of the machine, water vapor will be generated in the grinding cup cavity, and condensation water may form at the connector position. If condensation water forms at this position, it will enter the inside of the motor along the motor shaft. Over time, it will cause the iron core in the motor to rust, leading to motor failure and damage. Moreover, after the user disassembles the cup body for cleaning, there may be cleaning water at the bottom of the cup body, which may still cause the cleaning water to flow along the motor shaft to the inside of the motor assembly, damaging the motor.

[0003] There are some existing technologies that provide certain waterproof protection for motors. For example, the invention patent with application number CN202311464569.9 discloses a food processing machine. This solution arranges a hydrophobic part between the cup body and the motor assembly. When the shaft seal fails, the liquid in the cup body will leak out through the shaft hole along the surface of the rotating shaft, and the hydrophobic part can receive and collect the leaked liquid, thereby preventing the leaked liquid on the rotating shaft from flowing along the rotating shaft into the main unit of the motor, greatly improving the service life of the electrical components of the food processing machine and the safety of user use.

[0004] However, in the prior art, a waterproof barrier is mostly provided between the cup body and the motor. When water flows at the upper bracket or the shaft hole of the motor assembly, it will directly enter the motor body, causing the iron core of the motor cup body to rust. Therefore, the waterproof performance needs to be further improved, and the existing waterproof structure is complex, which is not conducive to reducing costs. Utility Model Content

[0005] The utility model provides a waterproof food processing machine, which solves the technical problem of poor waterproofness of the motor and high risk of water entering the motor component by arranging an isolation sleeve and arranging matching annular ribs and drainage ribs on the isolation sleeve, through improving the structure of the motor component itself.

[0006] The technical solution adopted by the utility model is:

[0007] The utility model provides a waterproof food processing machine, comprising a main unit with a built-in motor assembly and a cup body installed on the main unit, a crushing knife is arranged inside the cup body, the motor assembly is located below the cup body and drives the crushing knife to rotate, the motor assembly comprises an upper bracket, a lower bracket and a motor fixed between the upper bracket and the lower bracket, an isolation sleeve is arranged between the motor and the upper bracket, the isolation sleeve covers the upper surface of the motor and is penetrated by a through hole for a rotating shaft to pass through, an annular rib surrounding the through hole and a drainage rib arranged outside the annular rib are convexly arranged on the upper surface of the isolation sleeve, and the annular rib and the drainage rib cooperate to form a water retaining groove for outward drainage.

[0008] The utility model provides a waterproof food processing machine, by providing an isolation sleeve between the motor and the upper bracket, the isolation sleeve covers the upper surface of the motor, plays the effect of isolating water flow and noise, by convexly providing annular ribs and drainage ribs surrounding the through hole on the upper surface of the isolation sleeve, the annular ribs are used to surround the through hole to form a whole circle of closed enclosure, when water flows down from the upper bracket, the annular ribs block the water flow outside the through hole, the annular ribs and the drainage ribs cooperate to form a water retaining groove for outward drainage, the water flow blocked outside the through hole is temporarily stored in the water retaining groove and guided to the surroundings, during the drainage process, due to the heat generated by the operation of the motor, a part of the water flow temporarily stored in the water retaining groove can be diffused outward, and a part of it is evaporated by the heat of the motor to achieve drying, thereby reducing the risk of water flow flowing into the inside of the motor from the through hole, improving the waterproofness of the motor itself, making the waterproofness more direct, and preventing the motor core from rusting and damaging and failing, and at the same time, the evaporated water flow also has a heat dissipation effect on the motor, avoiding the temperature rise of the motor, and extending the service life of the motor, adopting the mode of cooperating with the annular ribs and the drainage ribs, the structure is simple, which is conducive to reducing production costs.

[0009] In a preferred embodiment, the upper bracket is provided with an outer hole for the shaft to pass through, the outer diameter of the annular rib is smaller than the inner diameter of the outer hole, and the upper surface of the upper bracket is convexly provided with a water retaining rib surrounding the outer hole.

[0010] An outer hole is provided on the upper bracket for the rotating shaft to pass through to realize transmission with the crushing knife. The outer diameter of the annular rib is smaller than the inner diameter of the outer hole, so that the annular rib plays an effective water-blocking role. A water-blocking rib surrounding the outer hole is convexly provided on the upper surface of the upper bracket to block the water from the water inlet source of the motor assembly. The water-blocking rib, annular rib and drainage rib form a water-blocking barrier in sequence, which further enhances the waterproof effect and further reduces the risk of water flowing into the motor.

[0011] In a preferred embodiment, the upper end of the annular rib extends into the outer hole;

[0012] Alternatively, the annular rib is provided with a drainage surface extending obliquely downward from the inside to the outside.

[0013] By extending the upper end of the annular rib into the outer hole, the annular rib and the water retaining rib overlap in the height direction, thereby avoiding the formation of a gap between the two, preventing water from flowing into the motor through the gap, and reducing the flow path of the water flow. When water enters the outer hole, the water flow can be directly blocked by the annular rib and then enter the water retaining groove between the annular rib and the drainage rib, thereby improving the waterproofness of the motor.

[0014] By arranging a drainage surface extending downward from the inside to the outside on the annular rib, the annular rib can be utilized to a certain extent to drain water flow or water droplets. Compared with the case where a lateral end surface is formed at the top of the annular rib, it can prevent water droplets from staying on the annular rib or splashing inward, and can guide water flow into the water retaining groove to evaporate or flow out, thereby improving the waterproofness of the motor.

[0015] In a preferred embodiment, the lower end of the water retaining rib protrudes relative to the lower surface of the upper bracket.

[0016] The lower end of the water retaining rib protrudes relative to the lower surface of the upper bracket, which strengthens the structural strength of the outer hole position of the upper bracket and extends the vertical height of the water retaining rib. It also facilitates the overlapping setting of the water retaining rib and the annular rib in the height direction, thereby improving the water retaining effect of both.

[0017] In a preferred embodiment, the raised height of the annular rib is H1, and the raised height of the drainage rib is H2, satisfying H1≥H2; the raised height of the annular rib is H1, satisfying H1≥2mm.

[0018] Since the annular rib is closer to the through hole than the drainage rib, and the distance between the upper bracket and the isolation sleeve is limited, setting H1≥H2 can avoid the problem of the annular rib being too low and the water-blocking effect being unsatisfactory, and at the same time avoid the problem of the drainage rib being too high, causing the overall height of the motor assembly to be large. Therefore, while reducing the height of the motor assembly, the water-blocking effect of the annular rib is ensured. The raised height of the annular rib is greater than or equal to 2mm, which can still play an effective water-blocking effect when too much condensed water flows in from the outer hole. Preferably, 2mm≤H1≤10mm to avoid the problem of the annular rib being too high, causing the overall height of the motor assembly to be large.

[0019] In a preferred embodiment, the drainage rib includes a first retaining rib extending circumferentially along the annular rib, and the first retaining rib is provided with a first opening.

[0020] By making the drainage rib include a first retaining rib extending circumferentially along the annular rib, processing is easy and cost is reduced. The first retaining rib is provided with a first opening, and a regular open annular water retaining groove is formed between the first annular rib and the annular rib. Condensed water temporarily stored in the water retaining groove can be discharged from the first opening, preventing water from flowing into the through hole when there is too much condensed water, thereby improving the waterproof effect.

[0021] In a preferred embodiment, the drainage rib further includes a second retaining rib surrounding the outside of the first retaining rib, and the second retaining rib is provided with a second opening staggered from the first opening.

[0022] By setting the second retaining rib, the annular rib, the first retaining rib and the second retaining rib are layered to guide water outward along the through hole, so that the speed of water discharge outward is slowed down, thereby forming a temporary storage trend in the water retaining groove, relying on the heat evaporation of the working motor to achieve the cooling effect of the motor.

[0023] In a preferred embodiment, the first retaining rib is provided with a plurality of symmetrically arranged first openings.

[0024] A plurality of first openings are provided on the first retaining rib, so that the water temporarily stored in the water retaining groove formed between the first retaining rib and the annular rib can flow into the water retaining groove between the second retaining rib and the first retaining rib, and the water evaporates and continues to be discharged at a position close to the outer periphery of the isolation sleeve, thereby improving the waterproof effect of the motor and achieving a cooling effect on the motor when the water evaporates.

[0025] In a preferred embodiment, the drainage rib is a spiral rib having one end connected to the annular rib and the other end extending outward in a spiral shape;

[0026] By setting the drainage ribs as spiral ribs, the water blocked by the annular ribs flows outward in a single direction, and the flow speed is slowed down, so that water vapor is formed during the flow process to take away the heat of the motor, thereby improving the temperature rise of the motor.

[0027] In a preferred embodiment, the drainage ribs include a plurality of segmented ribs extending radially outward around the annular ribs.

[0028] The drainage ribs are made of multiple radial segmented ribs surrounding the annular ribs, and water retaining grooves are formed between the segmented ribs and between the annular ribs and the segmented ribs. The water flow is temporarily stored in different parts of the isolation sleeve and evaporates directly after the motor is working, thereby reducing the heat of the motor.

[0029] In a preferred embodiment, the upper bracket is exposed from the main machine, the cup body is detachably mounted above the upper bracket, and the upper bracket is provided with an outer hole for the shaft to pass through and a water leakage hole staggered from the outer hole.

[0030] By exposing the upper bracket directly to the main machine, the upper bracket is used to form a supporting platform for supporting the cup body, and the overall height of the food processor is reduced. A drainage hole is also provided on the upper bracket, and the water flow is discharged away from the motor assembly through the drainage hole. When there is too much condensed water or water in the cup body, the water is diverted and guided to reduce the water flow reaching the outer hole position of the upper bracket, thereby reducing the water flow entering the through hole of the isolation sleeve and the inside of the motor.

In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described may be combined in an appropriate manner in any one or more embodiments or examples.

[0045] like Figure 1-5 As shown, the utility model provides a waterproof food processor, including a main unit 10 with a built-in motor assembly 30 and a cup body 20 installed on the main unit 10, wherein a crushing knife 21 is arranged inside the cup body 20, and the motor assembly 30 is located below the cup body 20 and drives the crushing knife 21 to rotate, as shown in FIG. Figure 2 As shown, the motor assembly 30 includes an upper bracket 31, a lower bracket 32 ​​and a motor 33 fixed between the upper bracket 31 and the lower bracket 32, an isolation sleeve 34 is provided between the motor 33 and the upper bracket 31, the isolation sleeve 34 covers the upper surface of the motor 33 and is penetrated by a through hole 341 for the rotating shaft to pass through, an annular rib 342 surrounding the through hole 341 and a drainage rib 343 arranged on the outside of the annular rib 342 are convexly provided on the upper surface of the isolation sleeve 34, and the annular rib 342 and the drainage rib 343 cooperate to form a water retaining groove 344 for outward drainage.

[0046] like Figure 1 As shown, the food processor provided in this embodiment is a food processor that does not need to be washed by hand, and the food processor also includes a slurry receiving cup 40 and a residual water box 50. Preferably, the host 10 is provided with an installation cavity for installing the cup body 20, and the cup body 20 is detachably installed in the installation cavity, so as to facilitate the user to disassemble and clean and remove the cup body 20 to pour out after preparing the thick slurry. In fact, the food processor can also be a fixed structure of the cup body 20 and the host 10, or the food processor is a wall breaking machine with a motor 33 placed below.

[0047] In a preferred embodiment, the upper bracket 31 is exposed to the main unit 10 , the cup body 20 is detachably mounted above the upper bracket 31 , and the upper bracket 31 is provided with an outer hole 311 for the shaft to pass through and a water leakage hole 313 staggered from the outer hole 311 .

[0048] By directly exposing the upper bracket 31 to the main unit 10, the upper bracket 31 is used to form a supporting platform for supporting the cup body 20, thereby reducing the overall height of the food processor. A drainage hole is also provided on the upper bracket 31, and the drainage hole is used to drain water away from the motor assembly 30. When there is too much condensed water or water carried by the cup body 20, the water is diverted and guided to reduce the water flow reaching the outer hole 311 of the upper bracket 31, thereby reducing the water flow entering the through hole 341 of the isolation sleeve 34 and the inside of the motor 33.

[0049] The waterproof food processing machine provided by the utility model has an isolation sleeve 34 between the motor 33 and the upper bracket 31, and the isolation sleeve 34 covers the upper surface of the motor 33 to isolate the water flow and the noise. The upper surface of the isolation sleeve 34 is provided with an annular rib 342 and a drainage rib 343 surrounding the through hole 341, and the annular rib 342 is used to surround the through hole 341 to form a full circle of closed enclosure. When water flows down from the upper bracket 31, the annular rib 342 blocks the water flow outside the through hole 341, and the annular rib 342 and the drainage rib 343 cooperate to form a water retaining groove 344 for outward drainage, which temporarily blocks the water flow outside the through hole 341. There is a water retaining groove 344 which guides the water in all directions. During the drainage process, since the motor 33 generates heat when it works, part of the water temporarily stored in the water retaining groove 344 can diffuse outward, and part of the water can be evaporated by the heat of the motor 33 to achieve drying, thereby reducing the risk of water flowing into the motor 33 from the through hole 341, improving the waterproofness of the motor 33 itself, and making the waterproofness more direct, thereby preventing the iron core of the motor 33 from rusting and being damaged and failing. At the same time, the evaporated water also has a heat dissipation effect on the motor 33, thereby avoiding the temperature rise of the motor 33 and extending the service life of the motor 33. The annular rib 342 and the drainage rib 343 are matched with each other, and the structure is simple, which is conducive to reducing production costs.

[0050] In a preferred embodiment, Figure 2-4As shown, the upper bracket 31 is provided with an outer hole 311 for the shaft to pass through, and the outer diameter of the annular rib 342 is smaller than the inner diameter of the outer hole 311. Figure 2 The upper surface of the upper bracket 31 is provided with a water retaining rib 312 surrounding the outer hole 311. Figure 3 , 4 As shown, the water retaining rib 312 may be optionally configured such that the lower end thereof protrudes relative to the lower surface of the upper bracket 31 .

[0051] like Figure 4 As shown, by providing an outer hole 311 on the upper bracket 31 for the shaft to pass through to achieve transmission with the crushing blade 21, the outer diameter R2 of the annular rib 342 is smaller than the inner diameter R1 of the outer hole 311, so that the annular rib 342 plays an effective water blocking role. Figure 5 As shown, a water retaining rib 312 is convexly provided on the upper surface of the upper bracket 31 around the outer hole 311, which is used to block the water from the source of the motor assembly 30. The water retaining rib 312, the annular rib 342, and the drainage rib 343 sequentially form a water retaining barrier, further improving the waterproof effect and further reducing the risk of water entering the motor 33. The lower end of the water retaining rib 312 protrudes relative to the lower surface of the upper bracket 31, which strengthens the structural strength of the outer hole 311 of the upper bracket 31 and extends the vertical height of the water retaining rib, and also facilitates the overlapping arrangement of the water retaining rib 312 and the annular rib 342 in the height direction, thereby improving the water retaining effect of both.

[0052] In a preferred embodiment, Figure 4 As shown, the upper end of the annular rib 342 extends into the outer hole 311 , that is, in this embodiment, the annular rib 342 and the water retaining rib 312 overlap in height direction.

[0053] By extending the upper end of the annular rib 342 into the outer hole 311, the annular rib 342 and the water retaining rib 312 overlap in the height direction, thereby avoiding the formation of a gap between the two, preventing water from flowing into the motor 33 through the gap, and reducing the flow path of the water flow. When water enters the outer hole 311, the water flow can be directly blocked by the annular rib 342 and then enter the water retaining groove 344 between the annular rib 342 and the drainage rib 343, thereby improving the waterproofness of the motor 33.

[0054] As another preferred embodiment of this embodiment, Figure 4 As shown, the annular rib 342 is provided with a drainage surface 3421 extending obliquely downward from the inside to the outside.

[0055] By providing a drainage surface 3421 extending downward from the inside to the outside on the annular rib 342, the annular rib 342 can be used to a certain extent to drain water or water droplets. Compared with the case where a lateral end surface is formed at the top of the annular rib 342, it can prevent water droplets from staying on the annular rib 342 or splashing inward, and can guide water to enter the water retaining groove 344 to evaporate or flow out, thereby improving the waterproofness of the motor 33.

[0056] Of course, it should be noted that, in fact, the situation where water droplets stay on the upper end of the annular rib 342 or splash inwards can be avoided by reducing the thickness of the annular rib 342 .

[0057] In a preferred embodiment, the protruding height of the annular rib 342 is H1, and the protruding height of the drainage rib 343 is H2, satisfying H1≥H2; the protruding height of the annular rib 342 is H1, satisfying H1≥2mm.

[0058] Since the annular rib 342 is closer to the through hole 341 than the drainage rib 343, and the distance between the upper bracket 31 and the isolation sleeve 34 is limited, setting H1≥H2 can avoid the annular rib 342 being too low and causing an unsatisfactory water-blocking effect, and at the same time avoid the drainage rib 343 being too high, causing the problem of the overall height of the motor assembly 30 being large. Therefore, while lowering the height of the motor assembly 30, the water-blocking effect of the annular rib 342 is ensured. The protruding height of the annular rib 342 is greater than or equal to 2mm, which can still play an effective water-blocking effect when too much condensed water flows into the outer hole 311. Preferably, 2mm≤H1≤10mm to avoid the problem of the annular rib 342 protruding too high causing the overall height of the motor assembly 30 to be large.

[0059] In addition, it should be noted that the present invention does not limit the specific structure of the drainage rib 343, and it can adopt any of the following implementation examples:

[0060] Implementation Example 1: Figure 1-5 In the embodiment shown, the drainage rib 343 includes a first retaining rib 3431 extending circumferentially along the annular rib 342, and the first retaining rib 3431 is provided with a first opening 3433, such as Figure 5 As shown, more preferably, the drainage rib 343 further includes a second blocking rib 3432 surrounding the outside of the first blocking rib 3431 , and the second blocking rib 3432 is provided with a second opening 3434 staggered from the first opening 3433 .

[0061] By making the drainage rib 343 include a first retaining rib 3431 extending circumferentially along the annular rib 342, the processing is easy and the cost is reduced. The first retaining rib 3431 is provided with a first opening 3433, and a regular open annular water retaining groove 344 is formed between the first annular rib and the annular rib 342. The condensed water temporarily stored in the water retaining groove 344 can be discharged from the first opening 3433, preventing the water flow from entering the through hole 341 when there is too much condensed water, thereby improving the waterproof effect. By setting the second retaining rib 3432, the annular rib 342, the first retaining rib 3431, and the second retaining rib 3432 are layered and drained outward along the through hole 341, so that the speed of water discharge outward is slowed down, thereby forming a temporary storage trend in the water retaining groove 344, relying on the heat of the motor 33 to evaporate, and achieve the cooling effect of the motor 33.

[0062] Alternatively, if Figure 5 As shown, the first retaining rib 3431 and the second retaining rib 3432 are respectively provided with a first opening 3433 and a second opening 3434 , and the first opening 3433 and the second opening 3434 are staggered.

[0063] In fact, two symmetrically arranged first openings 3433 may be provided on the first blocking rib 3431. Alternatively, the first blocking rib 3431 may be provided with four symmetrically arranged first openings 3433.

[0064] A plurality of first openings 3433 are provided on the first retaining rib 3431, so that the water temporarily stored in the water retaining groove 344 formed between the first retaining rib 3431 and the annular rib 342 can flow into the water retaining groove 344 between the second retaining rib 3432 and the first retaining rib 3431, and the water evaporates and continues to be discharged at a position close to the outer periphery of the isolation sleeve 34, thereby improving the waterproof effect of the motor 33 and achieving a cooling effect on the motor 33 when the water evaporates.

[0065] Of course, it is understandable that, in fact, the drainage rib 343 can also include a third retaining rib arranged on the periphery of the second retaining rib 3432, and so on, so that there are multiple circles of drainage ribs 343 around the annular rib 342 to form more water retaining grooves 344.

[0066] Implementation Example 2, such as Figure 6 As shown, the drainage rib 343 is a spiral rib having one end connected to the annular rib 342 and the other end extending outward in a spiral shape;

[0067] By setting the drainage ribs 343 as spiral ribs, the water blocked by the annular ribs 342 flows outward in a single direction, and the flow speed is slowed down, so that water vapor is formed during the flow process to take away the heat of the motor 33, thereby improving the temperature rise of the motor 33.

[0068] Implementation Example 3, such as Figure 7 As shown, the drainage rib 343 includes a plurality of segmented ribs extending radially outward around the annular rib 342 .

[0069] The drainage ribs 343 are made of multiple radial segmented ribs surrounding the annular ribs 342, and water retaining grooves 344 are formed between the segmented ribs and between the annular ribs 342 and the segmented ribs. Water flows temporarily at different locations on the isolation sleeve 34 and evaporates directly after the motor 33 is working, thereby reducing the heat of the motor 33.

[0070] The parts not described in the present invention can be realized by adopting or drawing on the existing technology.

[0071] The various embodiments in this specification are described in a progressive manner, and the same or similar parts between the various embodiments can be referenced to each other, and each embodiment focuses on the differences from other embodiments.

[0072] The above are only embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the scope of the claims of the present invention.
