Description

Technical Field

[0001] The invention relates to the technical field of motors, in particular to a high-power motor for kitchen appliances. Background Art

[0002] Electric motors are commonly known as motors. They refer to electromagnetic devices that realize the conversion or transmission of electric energy according to the law of electromagnetic induction. Electric motors are widely used in a wide range of fields. For example, in the field of kitchen appliances, axial flow exhaust fans and range hoods used in the kitchen all use electric motors as driving parts.

[0003] After searching for the utility model with patent publication number CN210468968U, it is disclosed that a sealed oil-proof plastic-sealed motor for kitchen electrical appliances is disclosed. The inner side of the end cover and the connection between the plastic-sealed casing are sealed with silicone to effectively improve the oil-proof effect of the motor, effectively avoid the occurrence of kitchen fumes entering the interior of the motor, thereby increasing the service life of the plastic-sealed motor. However, the motor casing is sealed as a whole. Since the internal electronic components of the motor will dissipate heat when the motor is running, if it is fully sealed, although it can well prevent fumes from entering the interior of the motor, relatively speaking, the heat is difficult to dissipate. Simply relying on the heat conduction of the casing to dissipate heat has a poor effect on heat dissipation, which makes it easy for a large amount of heat to be concentrated inside the motor. The heat will affect its performance and make its operation unstable. When the internal temperature is too high, the internal electronic components of the motor will easily be overheated and damaged. Therefore, the present invention proposes a high-power kitchen appliance motor. Summary of the invention

[0032] To make the purpose, technical solution and advantages of the embodiments of the present invention more clear, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0033] The embodiment provides a high-power kitchen electric motor, which is mainly used to solve the problem that the existing kitchen electric motor relies on full sealing of silicone, which can effectively prevent the entry of oil smoke, but relatively speaking, its heat dissipation effect is poor, and it is difficult to quickly dissipate heat, which makes the motor prone to overheating and damage. The following technical solutions are provided. Figure 1 - Fig.10 Make a detailed description:

[0034] A high-power kitchen electric motor comprises a base 1 and a motor housing 2 arranged on the base 1, a rotating shaft 3 rotatably penetrates the motor housing 2, preferably, the motor housing 2 comprises a main housing, two ends of the main housing are respectively provided with a front cover and a rear cover, the front cover and the rear cover can be connected to the main housing by screws, and a sealing gasket is provided at the connection when connected, so that the motor housing 2 can be detached and separated for easy maintenance, a stator 4 is provided on the inner wall of the motor housing 2, a rotor 5 is provided on the rotating shaft 3, and the rotating shaft 3 is driven to rotate under the cooperation of the rotor 5 and the stator 4, and a heat dissipation mechanism 6 for dissipating heat from the motor housing 2 is provided on the base 1, and by providing the heat dissipation mechanism 6, the motor housing 2 can be dissipated to avoid heat accumulation inside the motor housing 2;

[0035] An air inlet 7 is provided at one end of the rear end cover of the motor housing 2, and a sleeve 8 rotatably sleeved on the shaft 3 is provided at the front end cover of the motor housing 2. A first through hole 9 communicating with the sleeve 8 is penetrated through the outer surface of the shaft 3, and a second through hole 10 communicating with the sleeve 8 is penetrated through the front end cover of the motor housing 2, and an exhaust pipe 11 is connected to the rear end cover of the motor housing 2. When heat is dissipated, the airflow flows into the shaft 3 through the air inlet 7, and then flows into the sleeve 8 through the first through hole 9, and then flows into the motor housing 2 through the second through hole 10, so as to blow and dissipate heat to the electronic components inside the motor housing 2, and finally discharged from the exhaust pipe 11, so as to export the heat inside the motor housing 2;

[0036] The heat dissipation mechanism 6 includes a water tank 601 arranged on the base 1, and a partition 602 is arranged on the water tank 601, which is used to separate the water tank 601 into a filter chamber and a refrigeration chamber that are not connected to each other. Preferably, the water tank 601 includes a box body and a box cover arranged on the top of the box body. One side of the box body is connected to two drain pipes, and the two drain pipes are connected to the filter chamber and the refrigeration chamber respectively. In actual use, a valve is provided on the drain pipe, and the water is turned off or released by opening and closing the valve. A semiconductor refrigeration plate 603 is arranged in the refrigeration chamber. The cooling end of the semiconductor refrigeration sheet 603 is located in the refrigeration cavity, and the heat exchange end thereof is located outside the water tank 601. During use, liquid (water or coolant) needs to be added to the filter cavity and the refrigeration cavity respectively. The open end of the rotating shaft 3 rotates and extends into the refrigeration cavity. An inner wall on one side of the water tank 601 and the partition 602 are both connected with an L-shaped air inlet pipe 604. An air supply member 605 is provided on the water tank 601. The air supply member 605 is used to pressurize the external gas in turn through the two air inlet pipes 604. Preferably, as Figure 6As shown, the lateral end of the air inlet pipe 604 on the left is connected to the left side wall of the water tank 601, and its vertical end is located in the filter chamber. The lateral end of the air inlet pipe 604 on the right is connected to the partition 602, and its vertical end is located in the refrigeration chamber. It should be noted that the liquid in the filter chamber is lower than the lateral ends of the two air inlet pipes 604, and the liquid in the refrigeration chamber is lower than the air inlet duct 7 of the rotating shaft 3. When the motor is working, the external air flow first enters the liquid in the filter chamber from the left air inlet pipe 604, and the air flow needs to permeate out. When permeating, the oil and dust in the air flow will be intercepted in the liquid in the filter chamber. The clean gas that permeates through the water enters the liquid in the refrigeration chamber through the air inlet pipe 604 on the right, and then permeates out. When the clean gas is permeating, the semiconductor refrigeration sheet 603 is energized to cool the liquid, thereby cooling the clean gas. After cooling and drying The clean airflow then enters the motor housing 2 to blow and dissipate the heat of the internal electronic components, and is finally discharged from the exhaust pipe 11. The gas is filtered by a water filter, and then cooled and refrigerated. The cooled gas is circulated again. While blowing and dissipating the heat, the heat can also be extracted to improve the heat dissipation efficiency of the motor. Since the gas needs to be permeated with water twice, in order to ensure that the gas can be permeated with water smoothly, the circulating airflow is pressurized by the set air supply member 605, so that the airflow can smoothly flow through the filter chamber and the refrigeration chamber in turn. Since the air is continuously supplied to the inside of the motor housing 2, the air flow can carry the heat and be discharged through the exhaust pipe 11 under the action of wind pressure. Even if the exhaust pipe 11 is connected to the outside, it is mainly discharged to the outside under the action of wind pressure. There is wind pressure transported outward. Under the action of wind pressure, the oil smoke from the outside will not flow back to the motor housing 2 through the exhaust pipe 11;

[0037] In this solution, the motor housing 2 has an air inlet and an air outlet that are connected to the outside. When the air is taken in, the airflow will be permeated with water twice in sequence. The first permeation can filter out the oil smoke or impurities, and the second permeation can cool the airflow. While ensuring the heat dissipation of the motor, it can also prevent the oil smoke from entering the motor. At the same time, the clean and cooled airflow after water filtration does not directly enter the motor housing 2, but needs to circulate from the inside of the shaft 3 first. When the motor is running, the shaft 3 also has a certain temperature and heat. After the airflow is permeated with water, it contains a certain amount of moisture, which is discharged from the inside of the shaft 3. It can not only dissipate the heat of the rotating shaft 3, but also perform heat exchange to dissipate the heat of the rotating shaft 3, and also remove moisture in the airflow, so that the gas entering the motor housing 2 will not contain much moisture, and will not cause corrosion to the internal components of the motor. It should be noted that the rotating shaft 3 is a straight rod structure, and the gas flows faster along the inside thereof. The moisture in the airflow can be removed by heat exchange, but the airflow will not be overheated. Through two water-permeable filtrations, it can not only effectively prevent oil smoke from entering the motor, but also ensure the airflow circulation inside the motor to ensure the heat dissipation efficiency.

[0038] like Figure 6 As shown, in this embodiment, the air supply member 605 includes a guide rod 6051, which coaxially rotates and passes through the lateral sections of the two air inlet pipes 604 and one end of which is fixed to the rotating shaft 3 through a support rod, and the support rod is connected to the inner wall of the rotating shaft 3. The diameters of the support rod and the guide rod 6051 are smaller than the diameter of the air inlet duct 7, and will not block the air inlet duct 7 and will not affect the normal circulation of the airflow. Two first impellers 6052 are fixedly provided on the guide rod 6051, and the two first impellers 6052 are respectively located in the two air inlet pipes 604. When the rotating shaft 3 rotates, the guide rod 6051 is driven to rotate synchronously, thereby driving the two first impellers 6052 to rotate. Since the two first impellers 6052 are respectively arranged in the two air inlet pipes 604, suction is generated when they rotate, thereby pressurizing the airflow, so that the airflow can circulate quickly and penetrate water smoothly out of the liquid.

[0039] like Figure 6 As shown, in this embodiment, the inner wall of the water tank 601 is provided with a first conical shell 12 corresponding to the rotating shaft 3, and a second impeller 13 is provided on the guide rod 6051 and located in the first conical shell 12. Through the first conical shell 12, when the guide rod 6051 rotates, the second impeller 13 is driven to rotate synchronously. The second impeller 13 cooperates with the first conical shell 12 to generate suction. The suction is used to make the airflow that permeates the water and is located above the refrigeration cavity more easily enter the air inlet 7. At the same time, it is also used to pressurize the airflow in the air inlet 7 so that it can circulate quickly and enter the motor housing 2 more easily.

[0040] like Figure 6 As shown, in this embodiment, a rotating rod 14 is coaxially rotated in the vertical end of the air inlet pipe 604 located in the filter chamber. The top of the rotating rod 14 is transmission-connected to the guide rod 6051 through a bevel gear assembly 15. The bevel gear assembly 15 includes two bevel gears, which are respectively fixed on the rotating rod 14 and the guide rod 6051 and the teeth of the two are meshed. The bottom end of the rotating rod 14 is connected with a stirring piece 16. The stirring piece 16 has a U-shaped structure. When water permeability filtration is performed, oil and other impurities in the airflow will be trapped in the water in the filter chamber. There will be oil stains in the water in the filter chamber. After long-term use, the dirty oil will float on the liquid surface. Through the rotating rod 14 and the bevel gear assembly 15, when the guide rod 6051 rotates, the bevel gear assembly 15 will drive the rotating rod 14 to rotate, so that the stirring piece 16 stirs the water, causing it to generate a vortex, thereby preventing the oil stains from completely covering the liquid surface and ensuring the normal water permeability of the airflow. It should be noted that the liquid in the filter chamber needs to be replaced regularly to ensure normal use.

[0041] like Figure 4As shown, in the present embodiment, a second conical shell 17 and a third impeller 18 are fixedly provided on the rotating shaft 3 and in the casing 8. Through the third impeller 18, when the airflow flows from the rotating shaft 3 to the casing 8, the third impeller 18 rotates, so that the airflow in the casing 8 can flow more easily to the motor casing 2. At the same time, it is also used to increase the circulation speed of the airflow along the motor casing 2 and improve the heat dissipation efficiency of the motor. The second conical shell 17 can play a limiting role by utilizing its conical structure to prevent the wind force of the third impeller 18 from affecting the normal flow of the airflow from the rotating shaft 3 to the casing 8.

[0042] like Figure 1 and Figure 2 and Figure 7 As shown, in this embodiment, a water pipe 19 is spirally wound on the outer surface of the motor housing 2, and both ends of the water pipe 19 are connected to the refrigeration chamber of the water tank 601. A water delivery component 20 is provided in the water tank 601, which is used to transport the water in the refrigeration chamber to the water pipe 19 to form a circulation flow. Through the spirally wound water pipe 19, when the water in the refrigeration chamber is cooled, the water flow is transported along the water pipe 19 through the water delivery component 20, and then flows back to the refrigeration chamber, thereby forming a water flow cycle. When the water flow is flowing, it exchanges heat with the outer shell of the motor housing 2 through the water pipe 19, thereby reducing the temperature of the motor housing 2, thereby reducing the internal temperature of the motor housing 2. Preferably, the water pipe 19 adopts a copper pipe. In the overall design, the airflow enters the interior of the motor housing 2 for blowing and heat dissipation, and the cold water circulation performs heat exchange and cooling on the motor housing 2 from the outside, and the inner and outer double layers cool and dissipate heat, thereby improving practicality.

[0043] like Fig.10 As shown, in this embodiment, the water delivery member 20 includes a conduit 201 disposed in a water tank 601, and the two ends of the conduit 201 are respectively connected to a liquid inlet 202 and a liquid outlet 203, two ring plates 204 are arranged in the conduit 201 along its length direction, a first spring 205 is arranged on the inner wall of the conduit 201 at one side of the liquid outlet 203, and a liquid outlet control ball 206 is connected to the free end of the first spring 205, and a second spring 207 is arranged on the ring plate 204 near the liquid inlet 202, and the first spring 205 is connected to the liquid outlet control ball 206. The free ends of the second springs 207 are connected to a liquid inlet control ball 208. Preferably, the diameters of the liquid inlet control ball 208 and the liquid outlet control ball 206 are smaller than the inner diameters of the ring plate 204, the liquid inlet 202 and the liquid outlet 203. A sleeve 209 is vertically connected to the conduit 201. A piston rod 2010 is movably inserted in the sleeve 209. One end of the water pipe 19 is connected to the liquid outlet 203. A linkage member is provided on the rotating shaft 3. When the rotating shaft 3 rotates, the linkage member drives the piston rod 2010 to slide back and forth. Fig.10As shown, without external interference, the liquid inlet control ball 208 blocks the liquid inlet 202 under the elastic resistance of the second spring 207, and the liquid outlet control ball 206 blocks the ring plate 204 on the right side under the elastic resistance of the first spring 205, and the piston rod 2010 is driven to slide back and forth through the linkage. When the piston rod 2010 slides upward, under the action of pressure, the liquid inlet control ball 208 squeezes the second spring 207 and releases the blockage of the liquid inlet 202. At this time, the water flow in the refrigeration chamber flows from the liquid inlet 202 to between the two ring plates 204 and part of the water flows out. The piston rod 2010 slides up and down to squeeze the water, and under the action of pressure, the liquid inlet control ball 208 blocks the liquid inlet 202, and the liquid outlet control ball 206 squeezes the first spring 205 to expose the inner hole of the right ring plate 204. At this time, the water between the two ring plates 204 is discharged from the liquid outlet 203, and then flows along the water pipe 19. The piston rod 2010 slides up and down to achieve the function of pumping and draining water, so that the water in the refrigeration chamber is continuously transported to the water pipe 19, and then flows back to the refrigeration chamber from the other end to form a water circulation.

[0044] like Figure 7 As shown, in this embodiment, the linkage member includes a round wheel 21 eccentrically fixed on the rotating shaft 3, and a rocker arm 22 is rotatably sleeved on the round wheel 21. One end of the rocker arm 22 is hingedly connected to the piston rod 2010. When the rotating shaft 3 rotates, the round wheel 21 is driven to rotate synchronously. Since the round wheel 21 is eccentrically fixed on the rotating shaft 3, the rocker arm 22 is driven to shake, so that the rocker arm 22 pulls or resists the piston rod 2010, so as to achieve the effect of driving the piston rod 2010 to slide back and forth up and down. Preferably, the sleeve 209 is fixedly connected to the water tank 601, and the piston rod 2010 slides through the water tank 601. The setting of the linkage member makes it possible to use the rotation of the rotating shaft 3 as the power part for water delivery, which is achieved by the operation of the motor itself, thereby achieving an energy-saving effect.

[0045] like Fig. 9 As shown, in the present embodiment, a connecting ring 23 is provided on the inner wall of the exhaust duct 11, and a sealing plate 25 is connected to the connecting ring 23 through a third spring 24. The sealing plate 25 is in contact with and overlaps the pipe mouth of the exhaust duct 11. It should be noted that the elastic force of the third spring 24 is relatively small. In the absence of external interference, the third spring 24 pulls the sealing plate 25, thereby sealing the exhaust duct 11. When the motor is not in use, its air inlet and outlet ends are both in a sealing device to prevent external impurities from entering. When the motor is running, it is affected by the air flow inside the motor casing 2. Due to the continuous delivery of air flow into the motor casing 2, under the action of air pressure, the air flow inside the motor casing 2 flows to the exhaust duct 11, and under the pressure of the air flow, the sealing plate 25 is automatically pushed open without affecting the normal circulation of the air flow.

[0046] like Figure 5 and Figure 6As shown, in this embodiment, a recess is constructed on the water tank 601 and located at the bottom of the filter chamber, and the heat exchange end of the semiconductor refrigeration plate 603 is located in the recess. Preferably, the partition 602 is made of a heat-insulating material (extruded polystyrene board). By constructing the recess and locating the heat exchange end of the semiconductor refrigeration plate 603 in the recess, part of the heat is transferred to the filter chamber through the heat of the heat exchange end. It should be noted that the liquid in the filter chamber is not heated to form high-temperature hot water, but the water in the filter chamber is kept at a certain temperature (slightly higher than normal temperature) to prevent oil stains from condensing and facilitate air flow and water permeability.

[0047] The working process of the present invention is as follows: when cooling the motor, an external airflow is drawn in, and the airflow is first passed through water twice. The first time is used to filter the oil and dust impurities in the airflow, and the second time is used to cool the airflow. The cooled and filtered airflow is then circulated into the shaft 3, and then circulated into the motor housing 2 through the sleeve 8. By passing the airflow through water twice, the external oil and dust impurities will not be carried into the motor housing 2, and the motor can be effectively cooled by blowing. At the same time, when the motor is running, the shaft 3 rotates as a power source. The piston rod 2010 is driven to slide reciprocatingly up and down by the rocker arm 22, and the refrigerated water is transported to the water pipe 19 and then returned to the water tank 601 by the cooperation of the liquid inlet control ball 208 and the liquid outlet control ball 206, forming a cold water circulation. When the water flows in the water pipe 19, the shell wall of the motor shell 2 is exchanged with heat. With the overall structure, the air flow flows along the inside of the motor shell 2 to blow and dissipate heat. The cold water circulation exchanges heat and cools the motor shell 2 from the outside, and the inner and outer double layers cool and dissipate heat, thereby improving the heat dissipation efficiency of the motor, thereby improving practicality.

[0048] The above are only preferred specific implementation modes of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and inventive concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
