Description

Technical Field

[0001] The invention relates to the field of kitchen cooking appliances, and in particular to a food processor for making bread. Background Art

[0002] The food processor for making bread generally has both a stirring function and a heating function, and mainly includes: a machine body with a rotational driving function; a cup body mounted on the machine body; and a stirring device mounted in the cup body and rotationally driven by the machine body. The food processor may also have a heating device arranged around the cup body, so as to heat and bake the dough in the cup body to make bread.

[0003] For food processors with heating function, the heating device is usually in direct contact with the cup body, and a temperature sensor is provided on the cup body to feed back the temperature of the cup body to the food processor, thereby controlling the temperature of the food cooked in the cup body. Commonly used temperature sensors include positive temperature coefficient (PTC) thermistors and negative temperature coefficient (NTC) thermistors. Among them, temperature sensors made of NTC thermistors are widely used in household appliances such as water heaters, water dispensers, dishwashers, disinfection cabinets, and dryers. The principle is that the resistance value drops rapidly as the temperature rises.

[0004] 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 buckled in place, the knob reaches the set trigger position, triggering the micro switch to power on the machine, so that the motor drives the stirring device to rotate to stir the dough, and the heating device heats up to bake the dough. During the use of the food processor, since the rotation of the stirring device easily causes the cup lid to rotate, the knob may be out of the set trigger position with the rotation of the cup lid, which in turn causes the micro switch to disconnect, causing the food processor to abnormally power off and stop working. In addition, accidentally turning the cup lid during the operation of the food processor will also cause the food processor to stop working.

[0005] CN103565301A discloses an electric food processor. The electric food processor comprises a pot body, a handle, a pot body cover, a 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 body and the handle is fixed to the pot body, the pot body cover is locked on the pot body by rotating so that the block on the pot body cover enters the slot on the handle, and 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 to press the micro switch to turn it on. The stirring knife group of the electric food processor disclosed in CN103565301A is directly driven to rotate by a driving motor. Due to the high rotation speed of the driving motor, there may be a situation of insufficient torque when stirring highly sticky food such as dough. Therefore, it is often necessary to use a transmission mechanism to reduce the rotation speed and increase the driving torque.

[0006] CN109758006A discloses a food processor. The food processor comprises a cup body, a cup cover rotatably buckled on the cup body, a handle, a machine body, a driving motor located in the machine body, a pulley transmission mechanism, and a stirring knife group located in the cup body. The pulley transmission mechanism comprises a small pulley, a belt, a large pulley, and a transmission wheel. The small pulley drives the large pulley to rotate through the belt, which reduces the speed of the driving motor to a certain extent and increases the torque. However, a single pulley transmission mechanism is prone to uneven speed due to belt slippage.

[0007] These existing technical solutions cannot prevent the cup cover from accidentally rotating during the operation of the machine, causing the machine to stop working, which brings inconvenience in use. In addition, the separate pulley transmission mechanism may cause insufficient torque due to belt slippage.

[0008] Therefore, it is desired to provide a food processor that can overcome the above-mentioned shortcomings. Summary of the invention

[0009] In order to solve the deficiencies of food processors in the prior art, the present invention provides a food processor with an electric-controlled locking device and a multi-stage transmission mechanism.

[0010] The technical solution adopted by the present invention to solve the technical problem is to provide a food processor with an electric-controlled locking device, the food processor comprising: a screen assembly; a body assembly, which includes a body top cover, a body, body internals and a base, wherein the body assembly is provided with a motor, a transmission mechanism, a top micro switch, a bottom micro switch and an electric-controlled locking device; a bread cup assembly, which is configured to be placed in the body internals of the body assembly, the bread cup assembly comprising a cup cover, a cup body kit, a bottom cover, a heating tube, a stirring device and a rod linkage device, wherein the cup cover can be rotatably buckled on the cup body kit, the cup body kit is composed of an inner liner, a middle-layer fixing part, an outer shell and an outer shell cover, the heating tube is arranged on the middle-layer fixing part, the stirring device is arranged in the inner liner and is waterproofed by means of a sealing ring and an oil seal; and a base assembly. The middle-layer fixing part is also equipped with an NTC temperature sensor and a fuse. When the cup lid is buckled into place on the cup body kit, the cup lid turns on the top microswitch and at the same time turns on the bottom microswitch through the rod linkage device. The food processor can only be powered on and operated after both the top microswitch and the bottom microswitch are fully turned on. While the food processor is powered on, the NTC temperature sensor feeds back the temperature around the inner pot to the food processor. When the temperature of the heating tube is too high, the fuse will automatically blow, and the electronically controlled locking device will lock the cup lid in place until the food processor finishes working and the electronically controlled locking device is powered off to allow the cup lid to be opened.

[0011] According to a preferred embodiment of the present invention, the transmission mechanism comprises a combination of a pulley transmission mechanism and a planetary gear transmission mechanism.

[0012] According to a preferred embodiment of the present invention, the pulley transmission mechanism is located on the base and acts as a primary reduction mechanism, and the planetary gear transmission mechanism is located in the bottom cover and acts as a secondary reduction mechanism.

[0013] According to a preferred embodiment of the present invention, the pulley transmission mechanism includes a small pulley, a belt and a large pulley. The small pulley drives the large pulley to rotate through the belt, thereby reducing the rotation speed of the motor and increasing the torque.

[0014] According to a preferred embodiment of the present invention, the planetary gear transmission mechanism includes a sun gear, planetary gears, a planetary carrier and a ring gear, and the sun gear drives the planetary gears and the planetary carrier to rotate about the ring gear to further reduce the rotation speed and further increase the torque.

[0015] According to a preferred embodiment of the present invention, the top micro switch is located on the top of the body and is triggered by means of a top switch connecting rod, and the bottom micro switch is located on the base and is triggered by means of a bottom switch connecting rod.

[0016] According to a preferred embodiment of the present invention, silicone is provided around the top switch connecting rod, and the silicone can move up and down along with the top switch connecting rod.

[0017] According to a preferred embodiment of the present invention, the rod linkage device includes an upper connecting rod located between the side of the middle-layer fixing member and the outer shell and a lower connecting rod located in the bottom cover. When the cup body kit is placed in the inner part of the fuselage and the cup cover is snapped into place on the cup body kit, the flange on the cup cover presses down the top switch connecting rod to turn on the top micro switch, and the edge of the cup cover presses down the upper connecting rod of the rod linkage device to drive the lower connecting rod, and then presses down the bottom switch connecting rod to turn on the bottom micro switch.

[0018] According to a preferred embodiment of the present invention, the electrically controlled locking device includes a push rod. When the food processor is powered on and starts working, the electrically controlled locking device pushes out the push rod so that the top switch connecting rod presses against the cup cover, thereby locking the cup cover in place.

[0019] According to a preferred embodiment of the present invention, the latch of the cup cover is in the form of a protrusion provided on the flange of the cup cover.

[0020] Compared with the existing technical solutions, the food processor of the present invention has the following beneficial effects: on the one hand, an electrically controlled locking device is used to firmly lock the cup cover on the cup body when the food processor is running, so as to prevent the machine from stopping due to the accidental rotation of the cup cover during the operation of the food processor; on the other hand, the multi-stage deceleration brought by the pulley transmission mechanism and the planetary gear transmission mechanism makes the rotation speed of the stirring device of the food processor uniform and the torque sufficient, so that the stirred dough is free of particles and has good kneading properties. In addition, since the middle-layer fixing part is equipped with an NTC temperature sensor and a fuse, when the food processor starts the baking function, the NTC temperature sensor will continuously feed back the temperature around the inner pot to the food processor, so that the temperature control is accurate and the bottom is prevented from being burnt and burnt when baking bread; when the temperature of the heating tube is too high, the fuse will automatically break, which protects the heating tube and improves the safety performance during use. In addition, since the inner pot is equipped with an oil seal and a sealing ring, the inner pot can be put into the dishwasher for cleaning, making cleaning more convenient and quick.

Furthermore, terms such as "first," "second," and the like are not intended to emphasize the order or importance of the components referred to.

[0104] Reference Figure 1 , which shows a three-dimensional schematic diagram of a food processor according to an embodiment of the present invention. The food processor mainly includes a screen assembly 1, a body assembly 2, a bread cup assembly 3 and a base assembly 4. The screen assembly 1 is arranged on a panel of the body assembly 2, and the body assembly 2 is fixed on the base assembly 4. Preferably, the base assembly 4 is an electronic scale assembly for easy weighing. A control knob may be provided on the body assembly 2, and the function of the food processor can be controlled by the control knob. Preferably, the screen assembly 1 includes an eight-inch screen, on which the operating status of the food processor can be displayed.

[0105] Reference Figure 2 , which shows a cross-sectional schematic diagram of a bread cup assembly 3 of a food processor according to an embodiment of the present invention. The bread cup assembly 3 can be placed on the body assembly 2. Figure 3-Figure 4 A schematic diagram of a partial exploded view of the body assembly 2 of the food processor is shown in FIG. Figure 5-Figure 7 yes Figure 2 FIG. 2 is an exploded schematic diagram of the main parts of the bread cup assembly 3 shown in FIG.

[0106] First refer to Figure 3The body assembly 2 includes a body top cover 201, a body 208, a body inner part 210 and a base 225. The screen assembly 1 is arranged on the front panel of the body 208. The control knob is usually arranged on the front panel of the body 208 below the screen assembly 1. The top micro switch 203 is fixed to the top of the body 208 by the top micro switch bracket 204 and is closed by the body top cover 201. The top micro switch 203 is triggered by means of the top switch connecting rod 202. Silicone is arranged around the top switch connecting rod 202, and the silicone can move up and down with the top switch connecting rod 202. When the bread cup assembly 3 is placed in place and the cup cover 303 is buckled in place, the flange on the cup cover 303 presses down the top switch connecting rod 202 to turn on the top micro switch 203. The electric control locking device 207 is installed in the electric control locking device base 206 arranged below the top switch connecting rod 202. The electric control locking device 207 includes a push rod. When the food processor is powered on and starts working, the electric control locking device 207 pushes out the push rod to press against the top switch connecting rod connector 205, so that the top switch connecting rod 202 presses against the locking position of the cup cover 303, thereby locking the cup cover 303 in place. The locking position of the cup cover 303 is preferably in the form of a protrusion provided on the flange of the cup cover 303.

[0107] Figure 3 Also shown is a body inner part 210 on the body assembly 2 for placing the bread cup assembly 3. The body assembly 2 of the food processor according to the present invention is an L-shaped structure, and the body inner part 210 is arranged in a recess in the lower platform of the L-shape. The body inner part 210 has a shape matching the bottom cover 339 of the bread cup assembly 3, and the bread cup assembly 3 can be stably placed in the body inner part 210. The body inner part 210 can be equipped with a transmission cap 209 for a transmission mechanism and a bottom switch connecting rod 211 for a bottom micro switch 226. The bottom switch connecting rod 211 is supported in the body inner part 210 by a bottom switch connecting rod bracket 212.

[0108] Next, refer to Figure 4, which shows an exploded schematic diagram of the internal parts of the body assembly 2 of the food processor according to an embodiment of the present invention. These internal parts are mounted on a base 225 fixed on the base assembly 4. Specifically, the circuit board bracket 221 is vertically fixed on the base 225, and the motor bracket 218 is horizontally fixed on the base 225, which corresponds to the L-shaped structure of the body assembly 2. The circuit board 220 is fixed on the circuit board bracket 221, and the motor 213 is fixed on the motor bracket 218. The motor bracket 218 is also provided with a motor shockproof glue 219 to buffer the vibration caused by the rotation of the motor 213. The pulley transmission mechanism is installed in the space between the motor bracket 218 and the base 225. The pulley transmission mechanism acts as a primary reduction mechanism, which includes a small pulley 222, a belt 223 and a large pulley 224. The output rotating shaft of the motor 213 drives the small pulley 222 to rotate, and the small pulley 222 drives the large pulley 224 to rotate through the belt 223. The rotation of the large pulley 224 is output to the large pulley fixing column 215. Figure 3 The transmission cap 209 shown in the drawing, the large pulley fixing column 215 passes through the motor bracket 218 and is supported thereon by the bearing 214. During this transmission process, the speed decreases and the torque increases.

[0109] Figure 4 Also shown is a bottom micro switch 226 , which is fixed to the motor bracket 218 via a bottom micro switch bracket 227 . Figure 4 The connector pad 217 and the connector 216 shown in the figure will be further described in detail later in conjunction with the heating tube 316, the NTC temperature sensor 341 and the fuse 342.

[0110] Go to Figure 5 , which shows an exploded schematic diagram of the bottom cover portion 339 of the bread cup assembly 3 and the planetary gear transmission mechanism installed therein. The planetary gear transmission mechanism acts as a secondary reduction mechanism, which includes a sun gear 331, planetary gears 332, a planetary carrier 330 and a ring gear 327. A plurality of planetary gears 332 are placed around the sun gear 331 and sandwiched between the planetary carrier 330 and the planetary carrier bottom cover 333. Each planetary gear 332 is driven by the sun gear 331 to rotate around a corresponding pin on the planetary carrier 330. The sun gear 331, the planetary gears 332 and the planetary carrier 330 are installed in the ring gear 327. The lower part of the ring gear 327 is closed by the ring gear cover 335. A plurality of ball bearings 334 are provided between the ring gear cover 335 and the planetary carrier bottom cover 333 to facilitate the rotation of the planetary carrier bottom cover 333 relative to the ring gear cover 335. As described above in conjunction with Figure 4As described above, the output of the large pulley fixing column 215 is transmitted to the transmission column 338 through the transmission cap 209, and the sun gear fixing column 337 connected to the transmission column 338 drives the sun gear 331 to rotate, and the sun gear 331 then drives the planetary gear 332 and the planetary carrier 330 to rotate about the ring gear 327. The circular transmission block fixing column 329 inserted into the center of the planetary carrier 330 outputs the rotation of the planetary carrier 330 to the circular transmission block 325, thereby further reducing the rotation speed and further increasing the torque. The ring gear 327 and the ring gear cover 335 are fixed on the bottom cover part 339 through the upper gear box fixing cover 326, and the circular transmission block 325 is set in the central recess of the gear box fixing cover 326. Preferably, the circular transmission block fixing column 329 is inserted into the copper sleeve 328 to reduce wear. The sun gear fixing column 337 is supported in the ring gear cover 335 by means of a bearing 336. Figure 5 Also shown is a lower connecting rod 340, which is mounted on the bottom cover portion 339 through an elastic member. Figure 6 The role of the lower link 340 in the rod linkage is further described in detail.

[0111] Figure 6 3 is an exploded schematic diagram of a cup cover 303 and a part of a cup body kit of a bread cup assembly 3. The bread cup assembly 3 includes a cup cover 303, a cup body kit, a bottom cover 339, a heating pipe 316, a stirring device and a rod linkage device. Figure 6 As shown in the figure, the cup cover 303 has a central opening, in which a transparent cover 301 is provided for observing the situation in the cup. A silicone ring 302 is sandwiched between the cup cover 303 and the transparent cover 301 to strengthen the seal. The cup cover 303 can be rotatably buckled on the cup body kit. The cup body kit consists of an inner liner 304, a middle-layer fixing member 315, an outer shell 321 and an outer shell cover 313. The outer shell cover 313 is used to cover the middle-layer fixing member 315 and the outer shell 321. A pair of handles are provided on the outer shell cover 313, and the pair of handles are covered by the corresponding pair of handle covers 314. The upper connecting rod 323 of the rod linkage device is arranged between the middle-layer fixing member 315 and the outer shell 321. The heating pipe 316 is fixed to the middle-layer fixing member 315 by means of the heating pipe fixing member 317. The upper end of the upper connecting rod 323 of the rod linkage device extends out from the edge notch of the outer shell cover 313, and the lower end of the upper connecting rod 323 of the rod linkage device is fixed to the inner surface of the outer shell 321 by means of the upper connecting rod fixing member 324. A heating tube ceramic fixing block 318 and an upper connecting rod ceramic fixing block 322 are also provided between the middle fixing member 315 and the outer shell 321. An NTC temperature sensor 341 and a fuse 342 are mounted on the middle fixing member 315, which are fixed to the middle fixing member 315 by means of an NTC fixing glue 319 and a fuse fixing block 320, respectively. The heating tube 316, the NTC temperature sensor 341 and the fuse 342 are electrically connected to the above-mentioned combination through corresponding conductive pins. Figure 4 The connector 216.

[0112] Figure 7 304 and the stirring device disposed therein. The inner container 304 is provided with a handle 305 to facilitate the removal of the inner container 304. The stirring device includes a stirring blade 306, which is connected to the transmission member 312 and the above-mentioned combination through a stirring blade fixing column 309. Figure 5 The circular transmission block 325. The stirring blade fixing column 309 is supported in the fixing box 311 by means of the bearing 310, and the stirring blade 306 is also waterproof by means of the sealing ring 307 and the oil seal 308.

[0113] Reference Figure 8 , which shows a three-dimensional schematic diagram of a food processor removing a bread cup assembly 3 according to an embodiment of the present invention. Figure 4 It is understood that when the bread cup assembly 3 is placed in place, the conductive pins extending out of the bottom cover 339 of the bread cup assembly 3 can be electrically connected to the connector 216 fixed on the body inner part 210 of the body assembly 2 to energize the heating tube 316, the NTC temperature sensor 341 and the fuse 342.

[0114] Specifically, when the bread cup assembly 3 is placed in place on the inner body part 210 of the body assembly 2 and the cup cover 303 is rotated and buckled into place on the cup body kit, the flange on the cup cover 303 presses down the top switch link 202 to turn on the top micro switch 203, and at the same time, the cover edge of the cup cover 303 presses down the upper link 323 of the rod linkage device extending from the edge notch of the outer shell cover 313, and the upper link 323 drives the lower link 340 to extend out of the hole on the bottom cover 339 through shape matching, and then presses down the bottom switch link 211 to turn on the bottom micro switch 226. The food processor can only be powered on and operated after the top micro switch 203 and the bottom micro switch 226 are all turned on. During the power-on operation of the food processor, the NTC temperature sensor 341 continuously feeds back the temperature around the inner pot 304 to the food processor, and when the temperature of the heating tube 316 is too high, the fuse 320 will automatically blow. During this process, the electric-controlled locking device 207 always locks the cup cover 303 in place until the food processor finishes working, and then the electric-controlled locking device 207 is powered off to allow the cup cover 303 to be opened.

[0115] The food processor may further 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.
