Description

Multifunctional food processor

Technical Field

The utility model relates to the field of household appliances, in particular to a multifunctional food processor.

Background

At present, a meat grinder on the market is used for speed regulation by switching a diode parallel circuit through a micro switch, and the meat grinder only has two gears of full-speed gear and half-speed gear, for example, when a food processor disclosed in a patent CN216823025U presses different key switches, a motor outputs full speed or half-speed, and only can regulate the rotating speeds of the two motors, so that the processing mode of a product is limited, and more processing demands of a user are difficult to meet. The touch key triggering type meat grinder is characterized in that a user controls the motor to operate by lightly pressing the corresponding key to control the working time, and because the triggering stroke of the key is short, the touch feeling of the user is poor when the key is pressed, and especially when the key is pressed for a long time, the key is easy to lose efficacy, so that the motor is discontinuous in operation, and the reliability of the machine in use is affected.

More importantly, the existing multifunctional meat grinder generally comprises four gears of diced meat, minced meat, mashed meat and quick gear, and the four gears are all started by being pressed directly alone. However, since the final grain size requirements of the food materials under at least three functions of diced meat, minced meat and mashed meat are inconsistent, it is important to select the corresponding correct key gear. However, it is known that the size of the main frame of the household meat grinder is not very large, so that the keys are arranged on the main frame relatively tightly, which results in false triggering caused by the fact that the keys can be pressed to adjacent keys in actual operation. For example, the user originally wants to make the meat paste, but carelessly presses the meat paste function, and the actual effect of the subsequent meat paste is further affected.

Furthermore, the terms "first," "second," and the like, are used for descriptive purposes only and are not to be construed as indicating or implying a relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defining "a first" or "a second" may explicitly or implicitly include one or more such feature. In the description of the present application, the meaning of "a plurality" is two or more, unless explicitly defined otherwise.

As shown in fig. 1 to 6, the present application provides a multifunctional food processor, comprising a main machine 10, a pulverizing cup assembly 11 installed on the main machine 10, and a pulverizing knife 12 disposed in the pulverizing cup assembly 11, wherein a motor 13 and a control circuit 100 are disposed in the main machine 10, an output end of the motor 13 is connected with the pulverizing knife 12, the main machine 10 is provided with a key area, the key area is provided with a control key 14 and a plurality of function keys 15 connected in the control circuit 100, the control key 14 is a mechanical key, and the plurality of function keys 15 are used for selecting different processing modes; the motor 13 is adapted to run at a first rotational speed matching the selected machining mode when the control key 14 is continuously pressed and to stop when the control key is released from pressing. The operation time of the motor 13 is generally different from several seconds to several tens of seconds, so that the control key 14 is required to be continuously controlled after any one of the function keys 15 is selected to control the operation time of the motor 13.

Therefore, even if the user triggers by mistake, the user has a saving room, and the crushing effect of the food materials is not affected. For example, when the user selects the wrong function key 15, the user may power up again by powering down, or select the selected function key 15 again to cancel the function under the wrong function key, and then re-select.
