A heat dissipation structure of a food processor

Abstract

A heat dissipation structure for a food processor includes a main unit with an air duct chamber housing a motor and a cooling fan. The motor's first output shaft is connected to the cooling fan. The bottom of the main unit has an air outlet channel and several spaced-apart air outlets. Several guide channels are spaced-apart along the air outlet channel, each guide channel being independently configured. Each air outlet corresponds to a guide channel. The air duct chamber is connected to each guide channel, and each guide channel is connected to its corresponding air outlet. This food processor, by having several spaced-apart guide channels along the air outlet channel, each guide channel being independently configured, and the air duct chamber connected to each guide channel, and each guide channel connected to its corresponding air outlet, ensures that hot air flowing into the air outlet channel flows directly along the guide channels to the air outlet and then returns to the outside, without circling within the air outlet channel. This improves the motor's heat dissipation efficiency and prevents heat accumulation on the air outlet ring assembly, thus keeping the air outlet ring assembly at a low temperature.

Description

Technical Field

[0001] This utility model relates to the field of food processor technology, and in particular to a heat dissipation structure for a food processor. Background Technology

[0002] A food processor is a device that can cook food, such as an air fryer. An air fryer consists of a main unit with an air duct chamber inside. Inside the air duct chamber are a motor and a cooling fan. The first output shaft of the motor is connected to the cooling fan. At the bottom of the main unit is an air outlet ring assembly with a ring-shaped air outlet channel. Several air outlet holes are arranged in a ring around the perimeter of the air outlet ring assembly. The air duct chamber, air outlet channel, and air outlet holes are connected in sequence. When the cooling fan rotates, cold air from outside enters the air duct chamber, passes through the motor, flows into the air outlet channel, and finally returns to the outside through the air outlet holes to cool the motor. However, when hot air flows into the air outlet channel, some of the hot air flows along the ring-shaped air outlet channel, that is, this part of the hot air circles on the air outlet channel (i.e., the hot air stays on the air outlet channel and circles), instead of flowing to the air outlet holes. This affects the heat dissipation efficiency of the motor. Moreover, heat accumulates on the air outlet ring assembly, causing the air outlet ring assembly to become very hot. If a user touches the air outlet ring assembly, they may be burned.

[0003] Therefore, further improvements are necessary. Utility Model Content

[0004] The purpose of this invention is to provide a heat dissipation structure for a food processor that is simple in structure, has smooth airflow, high heat dissipation efficiency, is safe and reliable, and is highly practical, so as to overcome the shortcomings of the prior art.

[0005] A heat dissipation structure for a food processor designed for this purpose includes a main unit, an air duct chamber inside the main unit, a motor and a cooling fan inside the air duct chamber, and the first output shaft of the motor connected to the cooling fan. The main unit is characterized by having an air outlet channel and several spaced air outlets at the bottom, with several guide channels spaced apart on the air outlet channel. Each guide channel is independently configured, and the air outlets correspond one-to-one with the guide channels. The air duct chamber is connected to each guide channel, and the guide channels are connected to the corresponding air outlets.

[0006] An air outlet ring assembly is provided at the bottom of the main unit. The air outlet ring assembly includes an air outlet ring and a connecting ring arranged in sequence inside and outside. The connecting ring is located on the outside of the main unit. An air outlet channel is formed between the air outlet ring and the connecting ring. Air outlet holes are distributed in a ring around the air outlet ring, and guide channels are distributed in a ring on the air outlet channel.

[0007] The air outlet duct is equipped with several spaced baffles, and a guide flow channel is formed between two adjacent baffles. Each guide flow channel is separated from the others by the baffles.

[0008] Each air outlet is located between two adjacent partitions, and each partition is located between two adjacent air outlets.

[0009] The baffles are arranged in a ring around the air outlet ring and extend upwards, with the top of the baffles pressing against the connecting ring.

[0010] The air outlet duct is equipped with several spaced-out guide components, each of which is set independently, and the guide channel is set inside the guide component.

[0011] The flow guide is distributed in a ring around the air outlet ring. The flow guide is provided with a baffle. The guide channel and the connecting ring are separated by the baffle. There is a gap between the connecting ring and the baffle.

[0012] The main unit includes a body, an air duct chamber located inside the body, an air outlet ring assembly installed at the bottom of the body, and several ventilation holes arranged in a ring at the bottom of the body. Each ventilation hole corresponds to a guide channel, and the air duct chamber is connected to the guide channel through the ventilation holes.

[0013] A container assembly is located below the main unit, with air outlets positioned on the top of the container assembly and arranged in a ring around the outer perimeter of the container assembly.

[0014] The top of the main unit is equipped with an air inlet, which is connected to the ventilation duct chamber. The main unit is equipped with an air duct cavity located below the air duct chamber. The air duct cavity is equipped with a blower and a heating element. The second output shaft of the motor is connected to the blower. The container assembly is equipped with a cooking chamber, which is connected to the air duct cavity.

[0015] This invention relates to a food processor with several guide channels spaced at intervals along the air outlet channel. Each guide channel is independently configured, and the air duct chamber is connected to each guide channel. The guide channels are connected to the corresponding air outlets. When hot air flows into the air outlet channel, it flows along the guide channels to the air outlets and then returns to the outside, without circling in the air outlet channel (i.e., hot air stays in the air outlet channel and circles). This improves the heat dissipation efficiency of the motor and prevents heat from accumulating on the air outlet ring assembly, thus keeping the air outlet ring assembly at a low temperature and preventing burns to the user.

[0029] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0030] First embodiment: See Figures 1-10 The heat dissipation structure of this food processor includes a main unit 1, an air duct chamber 2 inside the main unit 1, a motor 3 and a cooling fan 4 inside the air duct chamber 2, the first output shaft of the motor 3 is connected to the cooling fan 4, the motor 3 is located below the cooling fan 4, and the air outlet end of the cooling fan 4 is set downward to dissipate heat from the motor 3. The bottom of the main unit 1 is provided with an air outlet channel 5 and several spaced air outlet holes 6. Several guide channels 7 are spaced on the air outlet channel 5, each guide channel 7 is set independently, and the air outlet holes 6 correspond one-to-one with the guide channels 7. The air duct chamber 2 is connected to each guide channel 7, the guide channels 7 are connected to the corresponding air outlet holes 6, and the air outlet holes 6 are connected to the outside. The food processor is an air fryer.

[0031] The bottom of the main unit 1 is equipped with an air outlet ring assembly, which includes an air outlet ring 10 and a connecting ring 11 arranged sequentially inside and outside the main unit 1. The air outlet ring 10 and the connecting ring 11 are connected by screws. The connecting ring 11 is located on the outside of the main unit 1 and is sleeved on the outside of the air outlet ring 10. An annular air outlet channel 5 is formed between the air outlet ring 10 and the connecting ring 11. Air outlet holes 6 are distributed in an annular pattern around the air outlet ring 10 and are set downwards. Guide channels 7 are distributed in an annular pattern on the air outlet channel 5. When hot air flows into the air outlet channel 5, it will flow along the guide channels 7 to the air outlet holes 6 and then return to the outside, without circling in the air outlet channel 5. This prevents heat from accumulating on the air outlet ring assembly, thus keeping the temperature of the air outlet ring 10 and the connecting ring 11 low and preventing the connecting ring 11 from burning the user. In addition, the connecting ring 11 does not need to be made of expensive high-temperature resistant materials, which can reduce the overall cost of the machine.

[0032] The air outlet duct 5 is provided with several spaced baffles 8, and a guide flow channel 7 is formed between two adjacent baffles 8. Each guide flow channel 7 is separated from the others by the baffles 8, so that each guide flow channel 7 is not connected to the others. As a result, the hot air entering the guide flow channel 7 can only flow along the guide flow channel 7 to the air outlet 6, and cannot flow to other guide flow channels 7. That is, the hot air cannot circulate in the air outlet duct 5.

[0033] Each air outlet 6 is located between two adjacent partitions 8, and each partition 8 is located between two adjacent air outlets 6. Each air outlet 6 is also separated from each other by the partitions 8, so that one guide channel 7 corresponds to one air outlet 6, preventing each guide channel 7 and each air outlet 6 from interfering with each other; the length of the guide channel 7 and the length of the air outlet 6 are basically the same.

[0034] The baffles 8 are distributed in a ring around the air outlet ring 10 and extend upward. The top of the baffles 8 abuts against the connecting ring 11, thereby playing a blocking role. In addition, the baffles 8 can improve the structural strength of the air outlet ring 10.

[0035] The air outlet ring 10 is surrounded by several first barrier ribs 21, and each air outlet 6 is directly separated by the first barrier ribs 21. The partition 8 is located at the position of the first barrier ribs 21.

[0036] The main unit 1 includes a body 13, an air duct chamber 2 is located inside the body 13, an air outlet ring assembly is installed at the bottom of the body 13, and a number of ventilation holes 14 are arranged in a ring at the bottom of the body 13. The ventilation holes 14 are spaced apart at the bottom of the body 13, and each ventilation hole 14 corresponds to a guide channel 7. The ventilation holes 14 are located at the bottom of the air duct chamber 2, and the air duct chamber 2 is connected to the guide channel 7 through the ventilation holes 14. The ventilation holes 14 guide the hot air flowing out of the air duct chamber 2 and guide the hot air flowing out of the air duct chamber 2 into the guide channel 7.

[0037] The bottom of the body 13 is provided with an air guide shroud 22, which is connected to the connecting ring 11 by a snap fastener. Ventilation holes 14 are distributed in a ring around the air guide shroud 22. Several second barrier ribs 23 are arranged in a ring around the air guide shroud 22, and each ventilation hole 14 is separated from the other by the second barrier ribs 23.

[0038] A container assembly 15 is located below the main unit 1. An air outlet 6 is located on the top of the container assembly 15 and is arranged in a ring around the outer periphery of the container assembly 15. The air blown out from the air outlet 6 flows downward along the outer wall of the container assembly 15 (container 25) to remove the heat from the outer wall of the container assembly 15. Due to the setting of the guide channel 7, the hot air can flow out smoothly from the air outlet 6, and then the cold air continuously enters the air duct chamber 2 for replenishment, which improves the heat dissipation efficiency of the motor 3. Moreover, the air blown out from the air outlet 6 continuously dissipates heat from the outer wall of the container assembly 15, resulting in good heat dissipation and preventing the outer wall of the container assembly 15 from getting too hot to the touch.

[0039] The top of the main unit 1 (body 13) is provided with an air inlet 16, which is connected to the ventilation duct chamber 2; such as Figure 1 and Figure 11 As shown by the arrow, when the cooling fan blade 4 is working, the outside cold air enters the air duct chamber 2 through the air inlet 16, then passes through the motor 3, flows out of the air duct chamber 2 through the ventilation hole 14, enters the guide channel 7, and finally returns to the outside through the air outlet 6 to cool the motor 3.

[0040] The main unit 1 has an air duct cavity 17 located below the air duct chamber 2. The air duct cavity 17 contains an air supply fan blade 18 and a heating element 19. The second output shaft of the motor 3 is connected to the air supply fan blade 18. The container assembly 15 contains a cooking chamber 20, and the air duct cavity 17 connects to the cooking chamber 20. The motor 3 is a dual-output shaft motor. The air outlet of the air supply fan blade 18 faces downwards, the heating element 19 is located below the air supply fan blade 18, and the cooking chamber 20 is located below the air duct cavity 17. The air duct chamber 2 and the air duct cavity 17 are separated by an air guide shroud 22. When the air supply fan blade 18 is working, the heat generated by the heating element 19 flows downwards and enters the cooking chamber 20 to heat the food inside. The hot air circulates vertically. The structure and principle of heating the cooking chamber 20 described above are existing technologies and will not be described in detail here.

[0041] The container assembly 15 includes a base 24 and a cooking container 25. The cooking container 25 has a support foot 26 on its bottom outer side. The base 24 has a limiting groove 27. The limiting groove 27 is fitted around the periphery of the support foot 26 and mutually limits and cooperates with it, so that the cooking container 25 is not easy to accidentally shift between the base 24 and the connection structure between the two is more stable. The cooking cavity 20 is set inside the cooking container 25. The bottom of the air outlet ring 10 is connected to a support ring 28, and the top of the cooking container 25 abuts against the support ring 28.

[0042] Second embodiment: See Figures 11-13 The heat dissipation structure of this food processor differs from that of the first embodiment in that: The air outlet duct 5 is provided with several spaced-out guide elements 9, each corresponding to an air outlet 6. The guide elements 9 cover the air outlet 6 downwards. Each guide element 9 is set independently. The guide channel 7 is set inside the guide element 9. The guide element 9 has a blocking effect, so that each guide channel 7 is not connected to each other. Thus, the hot air entering the guide channel 7 can only flow along the guide channel 7 to the air outlet 6, and cannot flow to other guide channels 7. That is, the hot air cannot circulate in the air outlet duct 5.

[0043] The air guide 9 is distributed in a ring around the air outlet ring 10. The air guide 9 is provided with a blocking part 12. The guide channel 7 and the connecting ring 11 are separated by the blocking part 12. There is a gap between the connecting ring 11 and the blocking part 12. This structure prevents the hot air in the guide channel 7 from approaching and contacting the connecting ring 11, thereby keeping the temperature of the connecting ring 11 low and effectively preventing the connecting ring 11 from burning the user.

[0044] The other parts not described are the same as in the first embodiment, and will not be analyzed or explained here.

[0045] The above describes the preferred embodiments of this utility model, illustrating and describing its basic principles, main features, and advantages. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made without departing from the spirit and scope of this utility model, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
