Description

Technical Field

[0001] The utility model relates to the technical field of food processors, and in particular to a food processor that is easy to dissipate heat. Background Art

[0002] A food processor is a multifunctional kitchen appliance that can knead dough, beat eggs, and stir food, saving time and effort. These appliances typically feature multiple gears to meet user requirements for mixing or kneading different ingredients. Mid- to high-speed gears increase motor speed, torque, or power. High-speed motors generate more heat, causing the machine to heat up during operation. Furthermore, the electronic components in food processors also generate heat during use. However, existing food processors typically feature side cooling vents that utilize natural airflow to dissipate heat. This method is slow and ineffective. Inadequate heat dissipation during prolonged operation can shorten the lifespan of the food processor. Utility Model Content

[0021] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions of the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings herein can be arranged and designed in various different configurations.

[0022] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but rather merely represents selected embodiments of the present invention. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without creative effort are also within the scope of protection of the present invention.

[0023] See also Figure 1-4This embodiment discloses a food processor that is easy to dissipate heat, which includes an upper shell 1 and a lower shell 2. The upper shell 1 is rotatably connected to the lower shell 2, that is, the upper shell 1 can rotate up and down relative to the lower shell 2, which is convenient for users to install the dough bucket and mixing tools. The lower shell 2 is provided with a first air inlet 221 and a plurality of support feet 7. The support feet 7 are arranged at the bottom of the lower shell 2, and the side wall of the upper shell is provided with a heat dissipation hole 11. A driving mechanism 4 and a limit cover 3 are installed in the upper shell 1. The driving mechanism 4 includes a motor 41 and a gear assembly 42. The two ends of the motor 41 are respectively provided with a first output shaft 411 and a second output shaft 412. The first output shaft 411 is connected to the gear assembly 42. The gear assembly 42 is used to drive accessories such as a dough hook and an egg beater to rotate. In this embodiment, the gear assembly 42 is a prior art and will not be described in detail here. A fan 6 is connected to the second output shaft 412, and the fan 6 is a low-speed fan. The second output shaft 41 and the fan 6 are located in the limit cover 3. The limit cover 3 is provided with a second air inlet hole 32. When the motor 41 is working, the fan 6 is driven to rotate, and the external cold air is sucked into the lower shell 2 from the first air inlet hole 221, and enters the limit cover 3 through the second air inlet hole 32. The cold air is dispersed in the gap between the limit cover 3 and the motor 41, reducing the diffusion area of ​​the cold air. The cold air can quickly exchange heat with the hot air generated by the motor 41, and then be discharged to the outside from the heat dissipation hole 11, so that the internal and external air convection dissipates heat, which greatly improves the heat dissipation effect inside the food processor.

[0024] See also Figure 2-3 In this embodiment, a wind collecting cover 5 is provided within the lower housing 2. The wind collecting cover 5 is provided with an air outlet 51, and the first air inlet 221 is embedded within the wind collecting cover 5. The wind collecting cover 5 defines the flow path of external cold air, allowing the cold air to more concentratedly dissipate heat from the motor 41. External cold air is drawn into the wind collecting cover 5 through the first air inlet 221, then blown out through the air outlet 51, and then enters the limiting cover 3 through the second air inlet 32.

[0025] Specifically, the limiting cover 3 is located above the air collecting cover 5. The limiting cover 3 is provided with a bevel 31, and the second air inlet 32 ​​is provided on the bevel 31. Since the internal installation space of the food processor is limited, the above design allows the second air inlet 32 ​​to be configured as a long strip, and the gaps between adjacent air inlet holes can also be configured to be larger, thereby increasing the overall aperture of the second air inlet 32 ​​and indirectly increasing the air intake of the limiting cover 3, thereby improving air convection and further accelerating heat dissipation. In this embodiment, the bevel 31 is formed by the arc chamfer between the side wall and the bottom wall, and the second air inlet 32 ​​is provided at one end of the bevel 31 close to the bottom wall, thereby shortening the flow path of the cold air.

[0026] It should be noted that, in this embodiment, the first air inlet 32 ​​can be provided at the bottom of the lower housing 2 or at the side wall of the lower housing 2. When the first air inlet 32 ​​is provided at the side wall of the lower housing 2, it is close to the bottom of the lower housing 2, thereby preventing the limiting cover 3 from blocking the position of the first air inlet 32 ​​and affecting air intake. Preferably, the first air inlet 32 ​​is provided at the bottom of the lower housing 2.

[0027] Please refer back to Figure 1-4 The lower housing 2 includes a bottom cover 22 and a lower shell 21. The bottom cover 22 is fixed to the bottom of the lower housing 21. The bottom cover 22 is provided with a chamber 222 opening upward. The air collecting cover 5 blocks the opening of the chamber 222. The chamber 222 is divided into an air inlet chamber 2221 and a power cord storage chamber 2222. The first air inlet hole 221 is provided at the bottom of the air inlet chamber 2221. The cold air sucked in through the first air inlet hole 221 can remove the heat from the surface of the power cord. The bottom of the air inlet chamber 2221 is recessed toward the upper housing 1 to prevent the first air inlet hole 221 from contacting the workbench and affecting the amount of cold air entering.

[0028] For details, please refer to Figure 4 The chamber 222 is located at one end near the edge of the bottom cover 22. The chamber 222 is enclosed by multiple side walls. A notch 2223 is provided in the first side wall of the chamber 222. A fixing hole 2224 is provided at the junction of the second side wall and the bottom of the chamber 222. The power cord passes through the notch 2223 and is led out through the fixing hole 2224 to the outside. When the wind condenser 5 blocks the opening of the chamber 222, it can secure the power cord. In this embodiment, the second side wall can be the side wall of the bottom cover 22.

[0029] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0030] The above-described embodiments merely represent several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present utility model patent shall be determined by the appended claims.
