Description

Motor heat dissipation wind guiding structure of food mixer

The novelty of the present invention belongs to the field of motor heat dissipation structure, and particularly relates to a motor heat dissipation air guiding structure for assisting motor heat dissipation in the casing of the food mixer.

According to the motor (5) installed in the casing (4) of the food mixer, heat is generated during operation, and for the purpose of heat dissipation, when the motor is cooled by the coaxial cooling fan (51), the casing ( 4) The air inlet hole (41) inhales the external cold air, and is forced to heat exchange and cool down by the cooling fan (51). Refer to the third figure; however, according to actual experience, the hot air after heat exchange is from the motor (5) After being discharged around, it still stays in the casing (4), and is repeatedly sucked in by the cooling fan (51), so that the effect of heat dissipation is not good, affecting the operation quality and the life of the parts, and how to improve it is necessary.

In view of this, the inventor of this case specially engaged in the design and manufacture of related food machinery for many years, accumulated rich experience, in-depth analysis and research, developed the "motor cooling and air guiding structure of food mixer" in this case, and after field trial verification, found It can effectively achieve the established practical efficacy goals, and is an ideal creation.

The new content of this case is aimed at how to solve the motor installed in the casing of the food blender. When the motor is running, heat will be generated. When the motor is cooled by the cooling fan, the heat is exchanged and the heat is discharged from the motor. The hot air in the shell causes poor heat dissipation and affects the quality of the operation and the life of the parts.

As a preferred solution, the present invention provides a motor heat dissipation air guiding structure of a food blender, which is disposed between a fan guard net of a heat dissipation fan of a motor in the casing and an air inlet hole of the casing, and is provided with an air guiding cover; When the cooling fan of the motor is operated, the air hood is connected to the casing through the air hood The air inlet hole absorbs the cold air from the outside to dissipate heat, and the hot air that remains in the casing after being exchanged by the heat exchange is blocked by the air hood, thereby ensuring that the cooling fan is simply sucked into the casing. The outside cold air can maintain the heat dissipation efficiency of the motor in an optimal state.

The first figure is a schematic diagram of the structure of the preferred embodiment of the present creation

The second figure is a schematic diagram of the state of use of the preferred embodiment of the present invention.

The third figure is a schematic diagram of the state of use of the conventional structure.

Referring to the first figure, the motor heat dissipation air guiding structure of the food blender comprises: an air guiding hood (1), which is a tubular body; a motor (2), which should be connected with a cooling fan (21) and a fan guard net (22); the motor (2) is installed in a casing (3) of the food mixer, and the casing (3) is provided with an air inlet hole (31); The cover (1) is installed between the fan guard net (22) of the motor (2) and the air inlet hole (31) of the casing (3), and is preferably tightly coupled; as shown in the second figure; Therefore, when the cooling fan (21) of the motor (2) is operated, the air inlet (31) connected to the casing (3) is sucked into the outside air through the air inlet (31) for heat dissipation; It should be emphasized that the hot air that remains in the casing after being exchanged from the motor after heat exchange is blocked by the created air hood (1), thereby ensuring that the cooling fan (21) is simply sucked into the casing. (3) The cold air outside, so that the heat dissipation efficiency of the motor can be maintained at an optimum state.

However, the heat-dissipating fan (21) that directly connects the air hood (1) to the motor (2) is also one of the possible embodiments of the creation.

In addition, the air hood (1) described in the present invention may be adapted to the space inside the casing or cooperated Various changes in the position of each component, such as horizontal, vertical or angular bending, are one of the possible implementations of the creation.

All of the above are only examples of the present invention. When it is not possible to limit the scope of the creation of the creation, that is, the simple equivalent changes, modifications and replacements made by the scope of the patent application and the content of the creation specification are all It should be within the scope of this creation patent.
