[0021] Refer to Figure 1-2 Describe a food processor according to an embodiment of the present invention.

[0022] In one embodiment, as Figure 1-2As shown in the figure, a food processor includes a base 1, an outer cover housing 2, a pulp cup 3, a crushing device, a pressure switch device 6, and a control circuit board 8. The outer cover housing 2 and the pulp cup 3 are both installed on the base 1, and the outer cover housing 2 covers the top of the pulp cup 3.

[0026] As another implementation manner of this embodiment, the control panel can be a touch panel. At this time, the first button and the second button can be touch buttons.

[0027] Among them, the first button can be set as a wall-breaking function key, and the second button can be set as a soymilk function key. The first button and the second button can be provided at the positions of A and B in Figure 1 The control circuit board 8 is configured to trigger the wall-breaking mode when the first button is pressed, control the motor 5 to drive the crushing blade 4 to rotate at a first speed suitable for wall-breaking, and at the same time control the heating device at the bottom of the cup to heat, so as to achieve the wall-breaking function; when the second button is pressed, the control circuit board 8 starts the soymilk mode, controls the motor 5 to make the crushing blade 4 rotate at a second speed suitable for soymilk making, and at the same time controls the heating device at the bottom of the cup to heat, to achieve high-temperature pressure maintenance inside the pulp cup 3, thereby realizing the soymilk making function.

[0028] During specific implementation, the user can select one of the two functions of wall-breaking and soymilk on the control panel, and the control circuit board 8 controls the rotation speed of the motor 5 and the heating of the heating device according to the user's selection, so as to achieve the wall-breaking or soymilk making function.

[0029] In the above embodiment, by providing a pulp cup 3 with a sealed cup mouth and a pressure switch device 6 on a traditional wall breaker, the internal cavity of the pulp cup 3 can be pressurized, so that the temperature inside the pulp cup 3 rises to a high temperature that meets the requirements of soy milk emulsification, thereby realizing the function of a soymilk maker. This food processor has both the functions of wall breaking and making soymilk, that is, it can be used for two purposes with richer functions.

[0030] In an implementation manner of this embodiment, the above food processor further includes a cooling device 7 provided on the side of the outer shell of the machine base 1. The lower end of the cooling device 7 is provided with an air inlet, and the cooling device 7 is connected to the control circuit board 8; an air-cooling cavity is formed between the inner wall of the outer cover housing 2 and the outer wall of the pulp cup 3. The top surface of the outer cover housing 2 is provided with an air outlet, and the air outlet can be a plurality of through holes evenly opened on the top surface of the outer cover housing 2. An air inlet is provided on the side surface of the outer cover housing 2, and the upper end of the cooling device 7 is correspondingly connected to the air inlet.

[0031] In another implementation manner of this embodiment, the above food processor further includes a cooling device 7 provided inside the machine base. The lower end of the cooling device 7 is connected with an air inlet, and the cooling device 7 is connected to the control circuit board 8; an air-cooling cavity is formed between the inner wall of the outer cover housing 2 and the outer wall of the pulp cup 3. The top surface of the outer cover housing 2 is provided with an air outlet, and the top surface of the machine base 1 is provided with an air inlet communicating with the air-cooling cavity. This implementation manner can further simplify the product structure.

[0032] In the above embodiment, the cooling device 7 includes an air inlet duct and a fan provided in the air inlet duct. The structure is simple, which is convenient for installation and maintenance, and the fan is connected to the control circuit board 8.

[0033] Among them, the side wall of the outer cover housing 2 is provided with a through hole at the corresponding position of the cooling device 7, and the upper end of the cooling device 7 communicates with the inner cavity of the outer cover housing 2 through this through hole.

[0034] During specific implementation, as Figure 1 shown by the flow direction of the cooling air flow represented by the arrow in the figure, the cold air blows from the air inlet through the cooling device 7 to the side wall of the pulp cup 3 to achieve cooling, and the hot air passing through the side wall of the pulp cup 3 is then discharged from the air outlet at the top of the outer cover housing 2 to the air-cooling cavity, which can quickly reduce the temperature inside the pulp cup 3 and achieve the effect of quickly opening the sealed cup cover.

[0035] In the above embodiment, the function of the wall breaker is that the motor 5 rotates at a high speed to crush the food in the crushing cup; the function of the soymilk maker is to first rotate at a high speed to crush the food in the crushing cup, and then heat to cook and emulsify the food in the cup at a high temperature to make soymilk. At the same time, the cooling device 7 is started to automatically complete the air-cooling effect, realizing the cooling and pressure reduction of the pulp cup 3, which is convenient for shortening the waiting time for opening the cover.

[0036] In this embodiment, as Figure 2As shown, the pressure switch device 6 includes a silica gel cap 61, a first ejector rod 62, a compression spring 63, a pressure plate 64, a second ejector rod 65, and a pressure switch 66 that are connected in sequence. The pressure switch 66 is connected to the control circuit board 8. An upper portion of the wall of the pulp cup 3 is provided with a pressure detection through-hole that communicates with the inner cavity of the pulp cup 3. The protruding end of the silica gel cap 61 extends into the inner cavity of the pulp cup 3 through the pressure detection through-hole.

[0037] In the above embodiment, the protruding end of the silica gel cap 61 is a circular arc convex surface. The rim of the silica gel cap 61 is arranged around the circular arc convex surface, and the side of the rim facing the pulp cup 3 fits on the outer surface of the side wall of the pulp cup 3, playing a sealing role.

[0038] The pressure switch device 6 is used to control the internal pressure of the pulp cup 3. During specific implementation, as shown by the pressure conduction direction represented by the arrow in Figure 2 When the internal pressure of the pulp cup 3 reaches the set pressure value, the pressure pushes the silica gel cap 61 and the first ejector rod 62, and conducts the pressure to the pressure switch 66 through the compression spring 63, the pressure plate 64, and the second ejector rod 65. The pressure switch 66 disconnects, and the control circuit board 8 controls the motor 5 and the heating device to stop stirring and heating. When the internal pressure of the pulp cup 3 is lower than the set pressure value, the pressure decreases, the silica gel cap 61 is pushed to reset, the pressure switch 66 conducts, and the control circuit board 8 controls the motor 5 and the heating device to start stirring and heating.

[0039] Based on the above embodiments, the following two working modes of the above food processor will be described in detail:

[0040] The wall-breaking production process may include the following steps: adding ingredients into the pulp cup 3, powering on the crushing device to work, and the motor 5 stirring and cutting the food at a high speed of greater than or equal to 30000 r / min. The working parameters can be set by the user himself or can be preset parameters built into the food processor. For example: it can be set that after the motor 5 runs at full speed for 10 seconds, then the motor 5 runs at full speed for 18 seconds, stops for 2 seconds, and keeps cycling until the work is completed.

[0041] The soy milk production process may include the following steps:

[0042] Pretreatment: Add soybeans and water into the pulp cup 3, cover the sealing cup lid to seal the pulp cup 3, start the heating device and the crushing blade 4, heat the temperature inside the pulp cup 3 to above 95 °C, and after the soybeans are crushed to less than 1 / 8 of the whole beans, the crushing blade 4 stops cutting;

[0043] High-temperature softening: Through the pressure switch device 6 and the heating device, continue to heat up the water-soybean mixture to 120 - 140 °C, and make the pressure in the pulp cup 3 be 120 - 134 kPa;

[0044] Emulsification and homogenization: Keep the temperature inside the pulp cup 3 at 120 - 140 °C. At the same time, start the crushing blade 4 to perform regular high-speed cutting to prepare soy milk. At this time, the motor 5 stirs and cuts at a high speed of greater than or equal to 15,000 r / min;

[0045] Cooling: Start the cooling device 7 and regularly operate the crushing blade 4 to cool the prepared soy milk to below 90 °C.

[0046] Since there is a sealed cup cover at the cup mouth, the pulp cup 3 has a tight seal, and the steam inside it cannot escape, resulting in an increase in pressure inside the pulp cup 3. Due to the increase in air pressure, the boiling point of water also rises accordingly. This means that in the high-pressure environment inside the pulp cup 3, water can remain in a boiling state at a temperature exceeding 100 °C, thus accelerating the cooking process of the food inside the pulp cup 3. To prevent potential safety hazards caused by excessive pressure inside the pulp cup 3, the above food processor is equipped with a pressure switch device 6, which can remind the control circuit board 8 when the pressure reaches a certain level. The control circuit board 8 can keep the pressure inside the pulp cup 3 within a safe range by controlling the motor 5 and the heating device.
