Blender

Abstract

The present invention relates to a blender which comprises: a jar in which a blade module in which food is crushed is placed; a body in which the jar is seated and which has an opened lower surface; a motor assembly which is provided inside the body and rotates the blade module; a cooling fan which is provided at the lower end of a rotary shaft of the motor assembly and rotates when the motor assembly is driven to thereby force air flow in the inside of the body; a PCB module which is placed between the circumferential surface of the body and the motor assembly; a base plate which blocks the opened lower surface of the body and includes a plate suction port via which air is sucked into the inside of the body, and a plate drain port via which air is discharged to the outside of the body; and an air guide which connects the motor assembly to the plate drain port to thereby form a discharge path of air, wherein the PCB module is placed at the upper side of the plate suction port and is cooled by the sucked air.

Description

technical field [0001] The present invention relates to cooking machines. Background technique [0002] Generally, a cooking machine is a household electrical appliance that uses a blade rotated by an electric motor to cut food contained in a container into small pieces, pulverize it into powder, or make it into a liquid state. It can also be called a mixer in general. [0003] In a common cooking machine, a container is placed on the top surface of a main body with a built-in motor, and when the container is installed, a blade inside the container is connected to a rotating shaft of the motor to be rotatable. Also, the user can drive the motor by operating the main body after putting the food in the container, and the blade can be rotated by the driving of the motor, so that the food can be crushed. [0004] In recent years, the above-mentioned cooking machines have been gradually developed into large-capacity cooking machines with larger containers, and cooking machines u...

AI Technical Summary

Problems solved by technology

[0009] However, even in this prior art, the discharge port is formed at the center of the bottom surface of the main body, and the suction port is formed outside the bottom surface of the main body, so there is a possibility that the main body may be distorted depending on the state of the ground on which the main body is arranged. Problems with poor inhalation or exhalation efficiency

[0010] In addition, in this prior art, since the suction port and the discharge port are adjacently arranged, there is also a problem that the heated air may be recirculated.
