Description

Anti-overflow reliable adds hot type food preparation machine

Technical Field

The utility model relates to a food preparation machine field especially relates to a reliable hot type food preparation machine that adds of anti-overflow.

Background

In a conventional heating type food processor, a heating device is generally provided below a stirring cup, and when the machine is started, the heating device heats a slurry in the stirring cup to an appropriate temperature by means of heat transfer.

When current food preparation machine is in order to guarantee the heating, the thick liquid can not spill over from the rim of a cup of stirring cup, generally set up anti-overflow spare on the bowl cover, in order to facilitate the assembly processing between anti-overflow spare and the bowl cover, anti-overflow spare all sets to the multistage, but can cause the resistance great like this, influence the transmission speed and the reliability of signal, especially with the conductive part of the signal conduction spare intercommunication of the handle upper end of stirring cup, the conductive part of anti-overflow spare contacts and wearing and tearing will influence the transmission speed and the reliability of signal with the signal conduction spare for a long time, thereby cause food preparation machine's anti-overflow unreliable, influence food preparation machine's normal use.

The existing anti-overflow piece is of a rod-shaped structure, and the food processor stirs and crushes food materials at a high speed by a blade, so that the materials in the stirring cup are in a high-speed rotation process. For the anti-overflow piece of the revolving body, after the food material is hung on the anti-overflow piece, more food material can be hung on the anti-overflow piece along with the rotation of the revolving body, and particularly after the food processing machine detects an anti-overflow signal, although the power supply of the heating body is immediately cut off, the food material is still in a heating state and continuously rises due to thermal inertia, so that the food material hung on the anti-overflow piece is increased. After the food material falls back, the food material hung on the anti-overflow piece drops due to the action of gravity to enable the anti-overflow piece to recover the original function, but part of the food material can be attached to the anti-overflow piece, the less the food material is required to be attached, the better the anti-overflow detection is, the better the food material is, due to the action of surface tension, the food material attached to the anti-overflow piece can shrink into a spherical shape, and at the moment, the rod-shaped anti-overflow piece just provides the optimal attachment surface for the attached food material, so that a large amount of food material can be attached to the anti-overflow piece and further influences the normal work of the anti-.

Meanwhile, the existing spill-proof piece is usually formed integrally with the cup cover, and the spill-proof piece is made of a metal material, and the volume of the spill-proof piece is smaller than that of the cup cover. When the cup cover is produced, on one hand, the spill-proof piece is greatly impacted in the injection molding cavity, and the possibility of deformation or displacement is high; on the other hand, the anti-overflow piece of metal material can make the plastic cool down rapidly and solidify after the plastic contact with hot melt state, and produces great difference in temperature around the plastic of other positions and the anti-overflow piece, and then makes the inside bad of bowl cover, influences the bowl cover reliability.
