Description

Stable and reliable food processor

Technical Field

The invention belongs to the field of food processors, and particularly relates to a stable and reliable connection triggering food processor without washing by hands.

Background

The traditional food processor comprises a main machine and a stirring cup arranged on the main machine, wherein a motor is arranged in the main machine, a crushing cutter driven by the motor is arranged in the stirring cup, and the stirring cup is connected with the main machine during operation, so that the crushing cutter can be driven by the motor to place food materials in the stirring cup, and the processing is realized by virtue of the crushing cutter. In order to prevent food from splashing out of the stirring cup in the processing process, a cup cover is usually arranged at the cup opening of the stirring cup. Because food processor is at the high-speed rotatory and drive crushing sword high-speed rotation of during operation motor, there is certain danger, needs to carry out operating condition's control to food processor, is provided with switch module in the host computer generally, and the stirring cup sets up corresponding trigger structure, and when the stirring cup broke away from the host computer, switch module control host computer outage was in order to make the motor stop work, avoided the user to take off the stirring cup and the danger that the motor continued to work brought at the during operation. In order to further promote the security of food processor, prior art still further links the trigger structure of stirring cup and bowl cover, when the bowl cover was opened, trigger structure just separated from with switch module, and the security of food processor is bigger promotes. However, the existing food processor has relatively single function, needs continuous participation of users in the use process, cannot meet the requirement that the users can obtain processed food without participation, and also needs manual cleaning after use, so that the ever-increasing use requirement of consumers cannot be met completely. Meanwhile, in the existing scheme, the switch component is usually arranged in the host, the motor is also arranged in the host, the safety component and the motor are only in an electric connection relationship, no correlation exists between the safety component and the motor in structure, the stirring cup is usually arranged on the host or is buckled and connected with the host, the stirring cup is in power connection with the motor, the switch component is triggered again, the motor and the switch component are not related in structure, the stirring cup needs to meet the power connection and the safety connection which are not related at the same time, the different installation dimension error requirements of the safety component and the motor are met, and the production and processing difficulty of the food processor is increased. Furthermore, because the power connection is not associated with the safety connection, the user is easy to mishandle when using, especially when the safety switch is triggered by the misoperation of the user, but the power connection part is not connected, and a high risk exists.

As an iterative lifting of the above-mentioned conventional food processor, there is also a food processor with automatic water feeding, pulping, automatic pulp discharging and cleaning, which is not washed by hand, and can complete all the working processes without participation of the user. Because the whole process does not need the participation of the user, the possibility of misoperation of the user is greatly reduced, and the potential safety risk of the food processor to the user is also greatly reduced. As a proposer of the hands-free technique, in order to make the hands-free food processor safer, in early solutions, a switch assembly was provided in the main machine and was triggered by means of a movable chamber connected to the main machine and forming a processing chamber. However, the continuous technical research and improvement prove that the scheme still has the following problems: because the switch assembly and the fixed cavity which is arranged in the host and forms the processing cavity together with the movable cavity are not directly related in structure, in the installation process of the food processor, the switch assembly and the fixed cavity are respectively arranged in the host, then the movable cavity is assembled with the host and processed, the installation dimension errors of the switch assembly, the installation dimension errors of the fixed cavity, the installation dimension errors of the movable cavity, the installation dimension errors of the host and the like are continuously overlapped, and when the movable cavity is installed and triggers the switch assembly, a very large trigger stroke is required to avoid that the movable cavity cannot normally trigger the switch assembly. Particularly, when the applicant sets flexible connection between the fixed cavity and the host, between the host and the motor, between the host shell and between the fixed cavity and the movable cavity for improving noise and crushing, the movable space between the fixed cavity and the movable cavity is larger, the requirement on the accuracy of the triggering structure of the movable cavity is higher, the requirement on the triggering stroke is longer, and the normal control and processing of the food processor are not facilitated. Although the probability of such a potential safety hazard is low, as a proposer of the hands-free technique, further technical improvement is required to solve such a potential safety hazard.
