Description

Technical Field

[0001] The present invention relates to the technical field of motors, and in particular to a driving motor for an energy-saving food processor. Background Art

[0002] As a multifunctional kitchen appliance, the food processor can realize various food processing functions such as kneading, stirring, and whipping cream through replaceable mixing heads, kneading hooks and other accessories. Its core power comes from the built-in drive motor, which usually uses a DC or AC motor. Its working principle is that the stator winding inside the motor generates a rotating magnetic field when energized, which interacts with the rotor, driving the output shaft to rotate, and then transmits power to the stirring component through transmission mechanisms such as belts and gears. By adjusting the motor speed and transmission ratio, the processing needs of different ingredients can be met.

[0003] The existing publication number CN119483103A discloses a switched reluctance motor for a food processor, comprising a protective shell, a regulating assembly being provided on the protective shell, the regulating assembly comprising a pad arranged in the protective shell, a stator being provided on the top of the pad, an extension rod being rotatably connected to the bottom of the stator, and the extension rod being mounted on the pad by bolts; a plurality of slide rails are distributed on the outside of the extension rod, and a resistance block is slidably connected to each slide rail, and one end of each resistance block is embedded with a reinforced magnetization sheet, a connecting disk is provided on the top of the stator, an offset groove is provided on the outside of the connecting disk, and a plurality of induction magnetic blocks are distributed on the top and bottom of the inner wall of the offset groove, and each induction magnetic block is respectively located at the top and bottom of the reinforced magnetization sheet; although the above technical solution can adjust the internal magnetic field distribution of the motor in real time by changing the waveform, peak value and effective value of the stator current, it drives the reinforced rotor rod and the connecting shaft to move continuously to the position of maximum magnetic field intensity, thereby realizing the influence on the output torque.

[0004] However, in the existing technology, when the drive motor is running at high load, such as kneading high-gluten dough for a long time, whipping cream at high speed, etc., the copper loss and iron loss of the stator winding and rotor will generate a large amount of heat, resulting in rapid accumulation of heat inside the motor. If the heat is not dissipated in time, the motor temperature will continue to rise, which can easily cause the motor efficiency to decrease, the noise to increase, and even shutdown protection. Traditional heat dissipation solutions generally use heat conduction diffusion of the metal casing and convection heat exchange of fixed linear air cooling channels. Some models are supplemented by axial fans for forced air cooling. Although some heat can be taken away by air convection, there is still a problem of insufficient heat dissipation path efficiency. In the compact space of the cylindrical casing, the fixed linear air cooling channel can only utilize the axial length of the motor casing. During heat dissipation, the airflow path is short and laminar. The contact time between the air and the movement components is limited, and it is difficult to fully take away the heat, resulting in low heat exchange efficiency. Summary of the Invention

[0005] The object of the present invention is to provide a drive motor for an energy-saving food processor to solve the problem of untimely heat dissipation of the drive motor for an energy-saving food processor proposed in the above-mentioned background technology due to low heat dissipation efficiency of the fixed linear air cooling channel and insufficient air flow turbulence effect.

[0006] The present invention provides a drive motor for an energy-saving food processor, which adopts the following technical solution:

[0007] A drive motor for an energy-saving food processor, applied to the energy-saving food processor, comprises a motor body, the motor body comprising a housing disposed in the energy-saving food processor and a core assembly disposed in the housing;

[0008] The heat dissipation device further comprises a plurality of heat dissipation units, which are distributed at equal intervals along the circumferential direction of the inner wall of the casing, and each group of the heat dissipation units comprises a flexible plate that is slidably fitted with the inner wall of the casing, elastic connectors fixedly connected to both ends of the flexible plate, a clamping member fixedly connected to the other end of the elastic connector, and a fixing seat fixedly mounted on the inner wall of the casing, the clamping member being rotatably connected to the fixing seat via a rotating shaft, a positioning wheel being abutted on the middle portion of one side of the flexible plate, the positioning wheel being fixedly connected to the inner wall of the casing, a driving wheel being symmetrically abutted on the other side of the flexible plate, a sliding post that slides along the inner wall of the casing, and a track corresponding to the sliding post being opened on the inner wall of the casing;

[0009] The slide post is slidably connected in the corresponding track and extends to the outside of the casing. A sealing ring fixedly connected to the slide post is rotatably sleeved outside the casing.

[0010] Furthermore, a temperature sensing unit is provided on the inner wall of the casing, and the temperature sensing unit includes a heat-conducting cavity hinged on the inner wall of the casing, a piston plate slidably connected to the heat-conducting cavity, and a transmission rod fixedly connected to the piston plate, a connecting rod is hinged between the other end of the transmission rod and the corresponding driving wheel, and an expansion unit is provided in the heat-conducting cavity;

[0011] In the initial state, a straight air-cooling channel is formed between adjacent flexible plates. The expansion unit expands due to heat and pushes the piston plate to move, causing the driving wheel to abut against the flexible plate and deform into an S shape, forming an S-shaped air-cooling channel between adjacent flexible plates.

[0012] Furthermore, a spring is provided on the transmission rod, and two ends of the spring respectively abut against the inner wall of the heat-conducting cavity and the piston plate.

[0013] Furthermore, the expansion unit is an air bag arranged in the heat-conducting cavity, and the air bag is filled with thermal expansion gas.

[0014] Furthermore, the bottom edge of the casing is provided with multiple groups of air inlets in the circumferential direction, and an adjustment unit is provided in the air inlet. The adjustment unit includes a baffle rotatably connected to the air inlet through an axis, and the baffle is provided with multiple groups of ventilation holes.

[0015] Furthermore, one end of the shaft extends outside the casing and is fixedly connected to a connecting arm, a sliding groove is provided on the connecting arm, a sliding rod is slidingly connected in the sliding groove, a ring is rotatably sleeved outside the casing, and the sliding rod is fixedly connected to the ring.

[0016] Furthermore, the collar is fixedly connected to one group of adjacent sealing rings, and the collar is driven to rotate synchronously by the rotation of the sealing ring.

[0017] Furthermore, a limiting support plate is fixedly connected to the air inlet, and when the baffle is fully closed, one side of its bottom is in contact with the limiting support plate.

[0018] Furthermore, the plurality of groups of air inlets are respectively located between adjacent flexible plates, and an air outlet channel is also provided on the housing.

[0019] Furthermore, torsion springs are provided at both ends of the rotating shaft, and both ends of the torsion springs are fixed on the clamping member and the fixing seat respectively.

[0020] Beneficial effects of the present invention:

[0021] By providing a heat dissipation unit and a temperature sensing unit, dynamic adjustment of the air-cooling channel is achieved. The temperature sensing unit drives the flexible plate in the heat dissipation unit to switch between a straight shape and an S shape according to the temperature changes of the core components. At low loads, the straight air-cooling channel is maintained to meet basic heat dissipation requirements and avoid excessive heat dissipation. At high loads, the thermal expansion gas controls the deployment of the airbag, pushing the flexible plate to form an S-shaped air-cooling channel. The S-shaped air-cooling channel significantly prolongs the residence time of the airflow in the heat dissipation area through a curved and folded path, so that the air and the core components are in contact for a longer time and can more fully take away the heat. At the same time, the bends of the S-shaped air-cooling channel force the airflow to generate turbulence to break the boundary layer, avoid local heat accumulation, and improve the heat dissipation efficiency.

[0022] By setting up an adjustment unit, adaptive control of the ventilation volume of the air inlet is achieved. When the load is low, the outside air enters the casing through the ventilation holes, limiting the air intake to avoid excessive heat dissipation and at the same time playing a dust-proof role. When the load is high, the baffles are opened, and multiple groups of baffles are distributed in a spiral shape along the circumference of the bottom of the casing, so that the outside air can enter the casing in large quantities and quickly along the spirally distributed baffles, forming high-speed turbulence in the S-shaped air cooling channel, thereby enhancing the heat dissipation effect.

[0039] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0040] Reference Figure 1-Figure 3 The present invention provides a driving motor for an energy-saving food processor, which is applied to an energy-saving food processor 100 and includes a motor body 200. The motor body 200 includes a housing 201 disposed in the energy-saving food processor 100 and a core assembly 202 disposed in the housing 201. The core assembly 202 includes a stator winding and a rotor component.

[0041] Reference Figure 3-Figure 7, also includes multiple groups of heat dissipation units 300, which are evenly spaced along the circumferential direction of the inner wall of the casing 201. Each group of heat dissipation units 300 includes a flexible plate 301 that slides in contact with the inner wall of the casing 201, elastic connectors 302 fixedly connected to both ends of the flexible plate 301, a clamping member 303 fixedly connected to the other end of the elastic connector 302, and a fixed seat 304 fixedly installed on the inner wall of the casing 201. The clamping member 303 is rotatably connected to the fixed seat 304 through a rotating shaft 305. Both ends of the rotating shaft 305 are provided with a torsion spring 3051, and the two ends of the torsion spring 3051 are respectively fixed to the clamping member 303 and the fixed seat 304. A positioning wheel 306 is abutted on the middle part of one side of the flexible plate 301. The positioning wheel 306 is fixedly connected to the inner wall of the casing 201. The other end of the flexible plate 301 The upper and lower sides are symmetrically abutted with driving wheels 307, and a sliding post 308 is fixedly connected to the driving wheel 307, which is guided and slidable along the inner wall of the casing 201. A track 309 corresponding to the sliding post 308 is opened on the inner wall of the casing 201. The sliding post 308 is slidably connected in the corresponding track 309 and extends to the outside of the casing 201. A sealing ring 310 fixedly connected to the sliding post 308 is rotatably sleeved on the outside of the casing 201. The sliding post 308 slides along the track 309 under the driving force, and the driving wheel 307 squeezes the flexible plate 301 accordingly. At this time, the positioning wheel 306 acts as a fulcrum, forcing the flexible plate 301 to bend, and the elastic connecting member 302 is extended by the hinged swing of the clamping member 303, eventually making the flexible plate 301 S-shaped. Synchronously, the sealing ring 310 is driven to rotate around the outer wall of the casing 201 by the displacement of the sliding post 308.

[0042] Reference Figure 4-Figure 5 and Figure 8-Figure 9 A temperature sensing unit 400 is provided on the inner wall of the casing 201. Specifically, the temperature sensing unit 400 is provided in two groups, and the two groups of temperature sensing units 400 are symmetrically arranged at the upper and lower positions on one side of the inner wall of the casing 201. The temperature sensing unit 400 includes a heat-conducting cavity 401 hinged on the inner wall of the casing 201, a piston plate 402 slidingly connected in the heat-conducting cavity 401, and a transmission rod 403 fixedly connected to the piston plate 402. A connecting rod 404 is hinged between the other end of the transmission rod 403 and the corresponding driving wheel 307. An expansion unit 405 is provided in the heat-conducting cavity 401. Specifically, the expansion unit 405 is an airbag arranged in the heat-conducting cavity 401, one end of the airbag is fixed to the inner wall of the heat-conducting cavity 401, and the other end of the airbag contacts with the piston plate 402. The airbag is filled with thermal expansion gas, which can be ammonia, nitrogen or air.

[0043] In the initial state, the flexible plate 301 maintains a straight shape under the tension of the elastic connector 302 and the constraint of the positioning wheel 306. A straight air cooling channel is formed between adjacent flexible plates 301, which meets the basic heat dissipation requirements under low load and avoids excessive heat dissipation. When the motor load increases and the temperature in the movement assembly 202 rises, the heat is transferred to the hot expansion gas in the airbag through the heat conduction cavity 401. The hot expansion gas expands after being heated, causing the airbag to deploy and push the piston plate 402 to slide axially along the heat conduction cavity 401. The transmission rod 403 and the connecting rod 404 abut against the drive wheel 307 and slide along the track 309. The sliding of the drive wheel 307 causes symmetrical thrust on both sides of the flexible plate 301. Due to the limiting effect of the middle positioning wheel 306, the flexible plate 301 bends and deforms from the initial straight state to an S-shape. The S-shaped air cooling channel formed by the two adjacent groups of flexible plates 301 changes the airflow path from axial straight flow to spiral flow, thereby further extending the residence time of the airflow in the heat dissipation area and improving the heat dissipation effect.

[0044] Reference Figure 8 A spring 406 is provided on the transmission rod 403, and the two ends of the spring 406 respectively abut the inner wall of the heat-conducting cavity 401 and the piston plate 402. When the motor load decreases and the temperature drops, the thermal expansion gas in the airbag contracts, and the piston plate 402 returns to its initial position under the tension of the spring 406.

[0045] Reference Figure 10-14 The bottom edge of the housing 201 is provided with a plurality of air inlets 203 in the circumferential direction. The air inlet 203 is provided with an adjustment unit 500. The adjustment unit 500 includes a baffle 501 rotatably connected to the air inlet 203 through a shaft 502. The baffle 501 is provided with a plurality of ventilation holes. The plurality of air inlets 203 are respectively located between adjacent flexible plates 301. Figure 3 The housing 201 is further provided with an air outlet passage 204 .

[0046] One end of the shaft 502 extends to the outside of the casing 201 and is fixedly connected to a connecting arm 503. A sliding groove 504 is provided on the connecting arm 503. A sliding rod 505 is slidingly connected in the sliding groove 504. A ring 506 is rotatably sleeved on the outside of the casing 201. The sliding rod 505 is fixedly connected to the ring 506. The ring 506 is fixedly connected to one group of adjacent sealing rings 310, and the ring 506 is driven to rotate synchronously by the rotation of the sealing ring 310.

[0047] When the motor is running at low load, outside air enters the casing 201 through the ventilation holes, flows through the linear air cooling channel at a lower flow rate, and takes away the small amount of heat generated by the low load operation of the motor. When the motor switches to high load operation, the core assembly 202 generates a large amount of heat. The expansion unit 405 expands due to the heat, pushing the piston plate 402 to move, causing the sliding column 308 to slide while the sealing ring 310 fixed thereto rotates synchronously. Since the ring 506 is fixedly connected to the sealing ring 310, the ring 506 rotates accordingly, causing the sliding rod 505 to slide in the sliding groove 504, driving the connecting arm 503 and the shaft 502 to rotate, thereby causing the baffle 501 to rotate to the open state. At this time, multiple groups of baffles 501 are spirally distributed along the circumferential direction of the bottom of the casing 201. Outside air can enter the casing 201 in large quantities and quickly along the spirally distributed baffles 501, forming high-speed turbulence in the S-shaped air cooling channel, thereby enhancing the heat dissipation effect.

[0048] A limiting support plate 507 is fixedly connected inside the air inlet 203. When the baffle 501 is fully closed, one side of its bottom is in contact with the limiting support plate 507. The limiting support plate 507 is in contact with the edge of the bottom side of the baffle 501 to support and limit the baffle 501 in the closed state.

[0049] The present invention provides a working principle of a drive motor for an energy-saving food processor: when the motor is running at low load, the initial pre-tightening force of the torsion spring 3051 enables the flexible plate 301 to maintain a straight shape under the tension of the elastic connector 302 and the constraint of the positioning wheel 306, and a straight air-cooling channel is formed between adjacent flexible plates 301. At this time, the outside air enters through the ventilation holes at a low flow rate, taking away a small amount of heat generated by the motor. When the motor switches to high load, the temperature of the core component 202 rises, and the heat is transferred to the airbag of the expansion unit 405 through the heat-conducting cavity 401. The hot expansion gas expands due to the heat, and the airbag expands to push the piston plate 402 along the axial direction. Sliding, the transmission rod 403 and the connecting rod 404 drive the driving wheel 307 to drive the sliding column 308 to slide along the track 309, and the positioning wheel 306 serves as a fulcrum to bend the flexible plate 301 into an S shape, forming an S-shaped air-cooling channel between adjacent flexible plates 301. At the same time, the displacement of the sliding column 308 drives the sealing ring 310 to rotate, and through the cooperation of the ring 506, the sliding rod 505 and the connecting arm 503, the baffle 501 is rotated to the open state, and multiple groups of baffles 501 are distributed in a spiral shape along the circumferential direction of the bottom of the casing 201. At this time, a large amount of outside air enters quickly, forming high-speed turbulence in the S-shaped air-cooling channel, greatly enhancing the heat dissipation effect.

[0050] When the motor switches from high load to low load, although the heat generation rate of the movement component 202 drops sharply, the hot expansion gas in the airbag cannot shrink instantly and remains in an expanded state for a short time. During this period, the piston plate 402 is continuously pushed by the gas, and the S-shaped deformation of the flexible plate 301 is maintained through the transmission rod 403 and the connecting rod 404, while the baffle 501 maintains an open angle, thereby quickly taking away the residual heat of the motor until the hot expansion gas dissipates heat through the heat conduction cavity 401 and shrinks. The piston plate 402 begins to retreat under the tension of the spring 406, triggering the flexible plate 301 to reset and the baffle 501 to close.

[0051] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
