Description

Technical Field

[0001] The invention relates to kitchen cooking appliances, and in particular to a food processor with stirring and / or heating functions. Background Art

[0002] Existing food processors usually have a stirring function, and mainly include: a body with a rotational driving function; a cup body mounted on the body; and a stirring tool mounted in the cup body and driven by the body to rotate. The food processor may also have a heater disposed in the bottom area of ​​the cup body to heat the food in the cup body.

[0003] The food processor usually controls the power supply through the cooperation of a micro switch and a cup lid that rotates and buckles on the cup body. When the cup lid is closed, the knob reaches the set trigger position, triggering the micro switch to power on the machine so that the motor drives the cutter to rotate to stir the food and / or the heater to heat the food. During the use of the food processor, as the cutter rotates to stir the food and / or the heater heats the food, the food may tumble up and down and continuously impact the cup lid, which may easily cause the cup lid to rotate. The knob may be separated from the set trigger position as the cup lid rotates, thereby causing the micro switch to disconnect, causing the food processor to abnormally shut down and stop working. In addition, accidentally rotating the cup lid during the operation of the food processor will also cause the food processor to stop working.

[0004] CN103565301A discloses an electric food processor. The electric food processor comprises a pot body, a handle, a pot body cover, a machine body provided with a micro switch, a first rod, a base fixed to the bottom of the pot body, a second rod and a third rod. When the base is mounted on the machine body and the handle is fixed to the pot body, the block on the pot body cover enters the slot on the handle by rotation, thereby locking the pot body cover on the pot body, the pot body cover can press the upper end of the first rod downward to move the first rod downward, and the lower end of the first rod can push the second rod outward from the base when moving downward, so that one end of the second rod protrudes from the base and pushes one end of the third rod, and the other end of the third rod moves in the opposite direction at the same time, thereby pressing the micro switch to turn it on.

[0005] CN206371963U discloses a food processing machine with stable operation, comprising a cup body with a handle, a base arranged below the cup body, a motor arranged in the base, a crushing knife arranged at the bottom of the cup body, a cup cover rotatably buckled on the cup body, and a micro switch for opening / closing the motor, wherein a downwardly arranged rotary buckle is provided on the cup cover, and when the cup cover is rotatably buckled on the cup body, the rotary buckle is located above the handle and triggers the micro switch, and the food processing machine also comprises an anti-retraction structure for preventing the rotary buckle from being disengaged when the micro switch is triggered, and the anti-retraction structure limits the rotary buckle on the cup cover to prevent the rotary buckle from being disengaged from the set trigger position due to the rotation of the cup cover, causing accidental power failure of the motor, wherein the anti-retraction structure is constructed by the snap-fitting of the anti-retraction rib and the anti-retraction groove.

[0006] These existing technical solutions cannot prevent the machine from stopping working due to food churning and impacting the cup lid and / or accidentally turning the cup lid during operation, causing inconvenience in use; in addition, the existing technical solutions usually use a single trigger mechanism to control the microswitch. As long as the microswitch of a single trigger point is turned on, the machine can be powered on, which cannot guarantee safety.

[0007] Therefore, it is desirable to provide a food processor that can overcome the above-mentioned disadvantages. Summary of the invention

Preferably, a top switch push rod waterproof member 214 is provided on the top switch push rod 215. The top micro switch 216 can be triggered by the cup cover 101 directly acting on the top switch push rod 215, and the bottom micro switch 210 can be triggered by the cup cover 101 acting on the bottom switch push rod 211 via the rod linkage device. The food processor can only be powered on and operated after at least the first and second micro mechanisms are all connected.

[0061] A stirring blade 107 may be provided in the cup body 1, and a driving motor 205 may be provided in the machine body 2. A transmission mechanism may also be provided in the machine body 2, and the rotation of the driving motor 205 may be transmitted to the stirring blade 107 through the transmission mechanism. The transmission mechanism may be a pulley transmission mechanism, which includes a small pulley 206, a belt 207, a large pulley 208 and a transmission wheel 209. In addition, a heating device 108 may be provided at the bottom of the cup body 1, and the heating device 108 may be heated by supplying power to the heating device 108. Preferably, the heating device 108 includes a heating film for heating.

[0062] Specifically, the cup cover 101 includes at least a first and a second trigger part, and the at least first and second trigger parts are preferably in the form of a card block. The cup cover 101 is provided with a card position for supporting the cup cover 101 with an electric-controlled locking device during the power-on operation of the food processor, thereby locking the cup cover 101 in place. The electric-controlled locking device includes an electromagnetic switch 204 and a top buckle 201, wherein the electromagnetic switch 204 is fixed on the electromagnetic switch base 203, and the electromagnetic switch base cover 202 covers the electromagnetic switch base 203. Preferably, a top buckle waterproof part 213 is provided on the top buckle 201. The card position of the cup cover 101 is preferably set on the first card block, and the details of the card position on the first card block of the cup cover 101 are described in detail. Figure 4 As shown in more detail in the figure, the latching position is a recess provided on the first latching block, and the edge of the first latching block and the recess thereon is configured to enable the first latching block to easily push down the top switch push rod 215 and / or the top buckle 201 when the cup cover 101 is rotated to lock or rotated to unlock.

[0063] Figure 5 1 is a schematic top view of different states of a food processor according to an embodiment of the present invention, respectively showing the states of the cup cover 101 being rotationally locked, the cup cover 101 being rotationally unlocked, and the cup cover 101 being removed.

[0064] In the first state of the cup cover 101 rotationally locked, the cup cover 101 is rotated and buckled on the cup body 1, and the first clamping block pushes down the top clamping block 201 and the top switch push rod 215 at the same time, and the top switch push rod 215 turns on the top micro switch 216. At the same time, the second clamping block acts on the first rod 104 of the rod linkage device, and the first rod 104 makes the second rod 105 of the rod linkage device linked, and the second rod 105 then pushes the bottom switch push rod 211 to turn on the bottom micro switch 210. In this way, the top micro switch 216 and the bottom micro switch 210 are turned on at the same time, and then the food processor can be powered on and various functions, such as stirring and / or heating functions, can be controlled through the control panel 3. When the food processor is powered on and running, the electromagnetic switch 204 is energized to push out the push rod to press against the top buckle 201, and the top buckle 201 is stuck in the position on the cup cover 101, thereby preventing the cup cover 101 from rotating. In other words, the top buckle 201 presses against the position of the cup cover 101 under the action of the push rod, thereby locking the cup cover 101 in place.

[0065] The food processor can stop running after the expected function is completed, which can be achieved by the timer switch or the preset function switch on the control panel 3. After the food processor stops running, the electromagnetic switch 204 is powered off so that the push rod returns to the initial position and releases the top buckle 201, thereby allowing the cup cover 101 to move relative to the top buckle 201, so that the top buckle 201 can be pushed down by the first clamping block of the cup cover 101 so that the cup cover 101 can be rotated and unlocked.

[0066] In the second state of the cup cover 101 being rotated and unlocked, the first and second blocks of the cup cover 101 are disengaged from the snap-fit ​​position, and the top switch push rod 215 and the bottom switch push rod 211 and the rods of the rod linkage device return to their initial stable positions, so that the top micro switch 216 and the bottom micro switch 210 are disconnected. The stable position of the push rod and the rod can be maintained by an elastic member.

[0067] In the third state of removing the cup cover 101, the stirring tool 107 in the cup body 1 can be seen. At this time, the top micro switch 216 and the bottom micro switch 210 are both in the disconnected state, and the drive motor 205 will not be powered on to drive the stirring tool 107 to rotate, ensuring safe use.

[0068] Preferably, a sealing ring is sandwiched between the cup body 1 and the cup cover 101. The cup cover 101 is usually provided with a through hole at its center to allow steam to be discharged when the food in the cup body 1 is heated. At the same time, in order to prevent the food in the cup body 1 from overflowing during heating, an anti-overflow cover can be inserted into the through hole. The anti-overflow cover can be a hollow cylinder with a top so that it can be used as a measuring cup.

[0069] The body may also include other necessary components to realize its functions, which are well known to those skilled in the art and will not be described in detail herein.

[0070] The above description is only used to exemplify the present invention and is not used to limit the present invention. It should be pointed out that for ordinary technicians in this field, several improvements, modifications and variations can be made to the present invention, but these improvements, modifications and variations should be regarded as falling within the scope of protection of the present invention without departing from the spirit of the present invention.
