       FIELD OF THE INVENTION 
       [0002]    The present application relates to a food processor, in particular, to a soybean milk maker. 
       BACKGROUND OF THE INVENTION 
       [0003]    The prior household soybean milk maker is divided into three types according to the working principle on bean crushing and soybean milk making thereof 
         [0004]    The first type of soybean milk maker is mounted, in the cup body thereof, with a mesh cover. Beans are placed in the mesh cover and are crushed by a cutter projected in the mesh cover. Then soybean milk made therefrom flows into the cup body through holes of the mesh cover. 
         [0005]    In the second type of soybean milk maker, the mesh cover is removed. Beans are placed in the cup body, and are crushed and made into soybean milk through high-speed rotating of the cutter. This type of soybean milk maker may be further provided, on an inner wall of the cup body, with a baffle to facilitate the crushing of the beans. With the baffle, the space in the cup body becomes irregular, and by changing circulation direction of the fluid, the material flowing to the wall of the cup under a radial force of the blade flows back to the proximity of blade to be crushed. 
         [0006]    In the third type of soybean milk maker, the mesh cover is replaced by a flow guiding member. Where performing the crushing, the material is placed in the cup body and is circulated inside and outside the flow guiding member under the pumping action of the crushing cutter to be crushed and made into soybean milk. 
         [0007]    However, to make soybean milk, a large space is needed in each of the above three types of soybean milk makers such that the material can be repeatedly circulated to the proximity of the crushing cutter to be crushed, thereby the circulation path of the material is long, which inevitably reduces the times that the material is in collision with the crushing cutter per unit of time, thereby reducing the crushing efficiency. It is found that the soybean milk making cycle of the prior household soybean milk maker generally lasts for about 25 minutes, some even last for at least 30 minutes. Thus the soybean milk making speed is too slow to be adapted to the rapid pace of modern life. Moreover, in the prior household soybean milk maker, a boiling process is generally performed such that the soybean milk is cooked, which further increases the time for making soybean milk since the time for the boiling of the soybean milk is long. 
       SUMMARY OF THE INVENTION 
       [0008]    In view of this, it is necessary to provide a soybean milk maker with high crushing efficiency to realize a rapid soybean milk making. 
         [0009]    It is provided according to the present application the following technical solutions to realize the above object. 
         [0010]    A rapid soybean milk making soybean milk maker includes a base and a control unit.

The motor and the crushing and cooking device are disposed on the base, the motor is electrically connected to the control unit, and the crushing cutter is located in the crushing and cooking device. While a material is mingled with water in the crushing and cooking device and is crushed by the crushing cutter into seriflux or paste, the seriflux or paste is heated and cooked by heat generated by frictions among the seriflux or paste, the crushing cutter and the crushing and cooking device. 
         [0011]    The crushing and cooking device has a volume of 50-1000 milliliters.

         [0013]    The crushing and cooking device is a closed container or a substantially closed container. 
         [0014]    The soybean milk maker further includes a heating unit electrically connected to the control unit. 
         [0015]    A diameter of a sphere having a volume equal to that of the crushing and cooking device is D, a diameter of a rotation plane of the crushing cutter is d, a ratio of D to d is α, and 1&lt;α&lt;3. 
         [0016]    The crushing and cooking device is a hollow sphere, a hollow cylinder or a hollow ellipsoid. 
         [0017]    The crushing and cooking device is provided with a feeding inlet and a discharging outlet. 
         [0018]    A ratio of a volume of the material and the water after being mingled to a volume of the crushing and cooking device is 1:2 to 1:1. 
         [0019]    The heating unit is disposed on the crushing and cooking device. 
         [0020]    The heating unit is disposed upstream the crushing and cooking device. 
         [0021]    The soybean milk maker further includes a water tank communicated with the crushing and cooking device, the heating unit is disposed on the water tank or on a water feeding passage communicating the water tank with the crushing and cooking device; or the soybean milk maker is further provided with an automatic feeding unit, the crushing and cooking device is provided with a feeding inlet, the automatic feeding unit is communicated with the feeding inlet of the crushing and cooking device, and the heating unit is provided on the automatic feeding unit. 
         [0022]    The heating unit is disposed downstream the crushing and cooking device. 
         [0023]    The soybean milk maker further includes a receiving device on which the heating unit is disposed; or the soybean milk maker further includes a receiving device and a discharging passage corresponding to the receiving device, the crushing and cooking device is provided with a discharging outlet, the discharging passage is communicated with the discharging outlet of the crushing and cooking device, and the heating unit is provided on the discharging passage. 
         [0024]    The crushing and cooking device is further provided with an opening on which a cover body is removably provided. 
         [0025]    The motor is horizontally provided in the base and is located at a side of the crushing and cooking device, and a shaft of the motor passes through the side wall of the crushing and cooking device and extends into the crushing and cooking device; or the motor is provided in the base and is located above the crushing and cooking device, the motor drives the crushing cutter to rotate through a driving shaft which passes through a hole in a top wall of the crushing and cooking device and extends downwards into the crushing and cooking device; or the motor is provided in the base and is located below the crushing and cooking device, the motor drives the crushing cutter to rotate through a driving shaft which passes through a hole in a bottom wall of the crushing and cooking device and extends upwards into the crushing and cooking device. 
         [0026]    In the present application, the crushing and cooking device is different from the open type large volume cup body of the existing soybean milk maker, particularly the small-space container having a volume of 50-1000 milliliters. The material and water are circulated in the space of the same container, the crushing cutter is larger relative to the effective work space of the container, the crushing cutter can be protruded into the material during the crushing, the material and water are restricted, by the crushing and cooking device, around the crushing cutter to be crushed, and the crushing and circulating path of the material is short, these are all within the scope of the crushing and cooking device of the present application. It should be noted that, the volume referred to herein should be interpreted as the volume of the effective work space of the crushing and cooking device. For example, for a hollow body having a “gourd” shape, the lower portion of the hollow body is the effective work space of the hollow body, as long as the volume of the lower portion is within the scope, it also falls within the protection scope of the present application. 
         [0027]    Term “substantially closed” mentioned in the present application means that the crushing and cooking device may also be in the following non-closed state. For example, a passage communicated with the crushing and cooking device is provided on the crushing and cooking device, and the passage is provided thereon with a hole or a slit; or the passage is sufficient long and is completely opened. As long as the structure is configured to be not only being unclosed but also being able to restrict the material and water therein for crushing such that the seriflux will not be spilled during the crushing process, the configuration is within the scope of the “substantially closed” according to the present application, and fall within the protection scope of the present application. 
         [0028]    Advantageous effects of the present application include the following. 
         [0029]    In the present application, the crushing and cooking device is different from the open-type large volume cup body of the existing soybean milk maker, the crushing and cooking device mentioned herein refers to the closed or substantially closed small-space container, particularly small-space container having a volume of 50-1000 milliliters. Since the crushing and cooking device has a small space and is closed or substantially closed, the probability that the material in the crushing and cooking device is crushed is increased, which not only increases the crushing efficiency, but also can make the crushing and cooking device be applicable to a higher ratio of the weight of the material to that of the water (for example, the ratio may be 2:1, which ratio can not be realized by the cup body of the existing soybean milk maker). Therefore, the soybean milk maker according to the present application can make food having a higher concentration, for example, mud-like or paste-like food. Meanwhile, the material and water in the crushing and cooking device occupies a large percent of the volume of the crushing and cooking device (compared with the material and water added in the cup body of the existing soybean milk maker, for example, the percent may be more than ½), thus more energy is provided for the crushing and colliding during the crushing process, thereby the temperature of soybean milk or soybean mud or soybean paste can be increased rapidly, which facilitates self-cooked of the soybean milk. At the same time, since heat is not easily to be dissipated, the soybean milk or soybean mud or soybean paste is continuously heated with the proceeding of the crushing, thereby is heated to a self-cooked temperature. 
         [0030]    The crushing and cooking device according to the present application is different from cup body of the soybean milk maker available in the market. The volume of the cup body of the soybean milk maker available in the market is generally large relative to the crushing cutter, therefore the material can not be well defined in the proximity of the crushing cutter, and it requires another structure such as a mesh cover, a flow guiding device or a baffle to help to increase the crushing effect. The crushing and cooking device of the present application is disposed adjacent to the crushing cutter to define the material in the proximity of the crushing cutter, to thereby form a drastic turbulence crushing effect and improve the crushing efficiency and the cooking efficiency. Since the cup body of the soybean milk maker available in the market has a large volume, the soybean milk maker can only be used to make low-concentration soybean milk having a good fluidity. 
         [0031]    In the present application, the crushing and cooking device is designed to have a volume of 50-1000 milliliters, which not only can ensure the normal demand for soybean milk but also can make soybean milk complying with the food safety requirements as soon as possible. In the present application, generally, high concentration soybean milk is made in the crushing and cooking device, and then is blended with water into soybean milk having a desired concentration. If the volume of the crushing and cooking device is smaller than 50 milliliters, soybean milk made therefrom is insufficient for a single person. If the volume of the crushing and cooking device is larger than 1000 milliliters, heat is dissipated too rapidly, it is difficult to provide a crushing cutter and a motor matching with the crushing and cooking device, and the time for the crushing and the cooking is long, which therefore is uneconomical. 
         [0032]    In the present application, a uniquely designed crushing and cooking device is employed. The dimension of the crushing and cooking device is small relative to the crushing cutter, the material is defined, by the crushing and cooking device, in the proximity of the crushing cutter where being crushed, and the peripheral wall of the crushing and cooking device is adjacent to the crushing cutter such that the material is always in an ideal cut state. To see from a macroscopic perspective, the crushing and cooking device is filled with the material during the crushing, and a drastic turbulence crushing and cooking effect is formed in the proximity of the crushing cutter. Besides, since the crushing and cooking device is a closed or substantially closed container, heat generated by frictions among the seriflux/paste, the crushing cutter and the crushing and cooking device can be highly gathered within a short time such that temperature in the crushing and cooking device can be rapidly increased, thereby the seriflux/paste can be heated and cooked. That is, the soybean milk maker of the present application is different from the existing soybean milk maker in that, it does not require a heating device to boil soybean milk, but can realize “self-heated” based on the motor and the crushing and cooking device. In this way, time separately spent for boiling soybean milk after the material is crushed in the existing soybean milk maker is eliminated by the present soybean milk maker, which greatly reduces the overall time for making the soybean milk, and the soybean milk can be made within five minutes, which further makes it possible for a ready-to-drink type soybean milk maker. Where water is injected into the crushing and cooking device, the crushing cutter stirs the water such that the peripheral wall of the crushing and cooking device is automatically washed. During the crushing, only a small quantity of water and beans are blended and crushed in the present soybean milk maker, in this way, the crushing cutter only stirs and crushes the “minimum” material, which not only saves energy but also increases bean content in per unit volume, thereby the crushing efficiency and crushing thinness of the material are improved. Moreover, the concentration and the volume of soybean milk finally made by the soybean milk maker can be adjusted by controlling the amount of water or other liquid blended with the soybean milk, which can meet individual needs of consumers. 
         [0033]    It is preferable that the crushing and cooking device is configured to have a volume of 100-500 milliliters. In this way, soybean milk after being blended with water can meet the demand of a single person and can also meet the demand of a three-person family, thereby having a good applicability. 
         [0034]    Since the crushing and cooking device is a closed container or a substantially closed container, it can prevent heat from dissipating, thus heat generated by frictions among the seriflux/paste, the crushing cutter and the crushing and cooking device can be highly gathered within a short time, thereby temperature in the crushing and cooking device can be increased rapidly, and thus the seriflux/paste can be heated and cooked. 
         [0035]    Water and/or material can also be heated by a heating unit of the soybean milk maker before being crushed and cooked or during the crushing and cooking process, such that a high temperature, for example, at least 90, is maintained in the crushing and cooking device, which can assist the cooking, therefore the time for the making of the soybean milk is further reduced. 
         [0036]    The ratio of the diameter of the rotation plane of the crushing cutter to the diameter of the sphere having a volume equal to that of the crushing and cooking device is defined to be 1:3 to 1:1, which not only can ensure a smooth circulation of the material but also can define the material more efficiently such that the material is in the proximity of the crushing cutter, to thereby enhance the crushing effect of the crushing cutter. 
         [0037]    The crushing and cooking device may be a hollow sphere, a hollow cylinder or a hollow ellipsoid. 
         [0038]    The heating unit may be disposed on the crushing and cooking device, or be disposed upstream or downstream the crushing and cooking device. For example, the heating unit is disposed on the water tank or on a water feeding passage communicating the water tank with the crushing and cooking device; or the soybean milk maker is further provided with an automatic feeding unit, the crushing and cooking device is provided with a feeding inlet, the automatic feeding unit is communicated with the feeding inlet of the crushing and cooking device, and the heating unit is disposed on the automatic feeding unit; or the soybean milk maker further includes a receiving device and a discharging passage corresponding to the receiving device, the crushing and cooking device is provided with a discharging outlet, the discharging passage is communicated with the discharging outlet of the crushing and cooking device, and the heating unit is disposed on the discharging passage. 
         [0039]    The soybean milk maker of the present application employs a crushing and cooking device that can be opened and closed, therefore the user can open the cover body of the crushing and cooking device to add material into the crushing and cooking device where using the soybean milk maker, in this way, the feeding mechanism and/or the water feeding mechanism may be eliminated from soybean milk maker, therefore the structure of the soybean milk maker is more compact and it is applicable to be used in household, besides the cost of the whole maker is also reduced. Moreover, to clean the crushing and cooking device, an automatic cleaning can be performed by sealing and closing the cover body and the crushing and cooking device, and a manual cleaning can also be performed by the user after the cover body is opened, therefore, many choices are provided in use and it is more convenient. Moreover, the crushing and cooking device has a certain volume, where being added with the material manually, the problem of bad crushing and cooking due to adding too much material can be effectively avoided, which has a “Fool-Proof” effect and can ensure the quality of soybean milk. Further, the user can also open the cover body anytime anywhere to replace the crushing cutter according to various materials to be crushed and cooked. 
         [0040]    The motor of the soybean milk maker is horizontally provided on the base and is located at a side of the crushing and cooking device, the center of gravity of the whole soybean milk maker is lowered, the stability of the whole maker is improved, and the probability that the seriflux or water enters the motor and the control unit during a manual operation is reduced, thus the making of the soybean milk is more safe and reliable. Further, the crushing cutter is brought into direct contact with the material and is driven by the motor to rotate at a high speed to thereby crush the material. Thereby the crushing efficiency is improved. 
         [0041]    The motor of the soybean milk maker of the present application is extended in the crushing and cooking device from the bottom portion of the crushing and cooking device such that the cutter shaft or the shaft of the motor is always in the seriflux during the making of the soybean milk, that is, the shaft of the motor is washed by the seriflux continuously. In this way, most of the heat generated by the friction between the shaft of the motor shaft or the cutter shaft rotated at a high speed and the bearing will be directly transferred to the seriflux, which, on the one hand, can reduce the temperature of the shaft of the motor or the cutter shaft to prevent the soybean milk from being burned due to the overheat of the shaft of the motor or the cutter shaft, meanwhile the shaft of the motor or the cutter shaft is cleaned by the washing of the seriflux, and thus the problem that the shaft of the motor or the cutter shaft is stuck and can not be cleaned up is solved; on the other hand, it also facilitates the cooking of the soybean milk, thereby the time for making the soybean milk is further reduced. Further, since the soybean milk maker is provided with a base, the center of gravity of the whole soybean milk maker is lowered and the stability of the whole maker is improved. Still further, since the crushing cutter is in direct contact with the material and is driven by the motor to rotate at a high speed to crush the material, the crushing efficiency is improved.

     DETAILED DESCRIPTION 
       [0058]    The present application is further described in detail hereinafter in conjunction with the figures and the embodiments. 
         [0059]    The soybean milk maker according to the present application is applicable to make seriflux or paste-like food, for example, soybean milk and rice paste. The material mentioned herein refers to raw material before crushed such as beans or rice. 
       First Embodiment 
       [0060]    Referring to the soybean milk maker according to a first preferred embodiment of the present application shown in  FIGS. 1 to 3 . The soybean milk maker  10  includes a base  11 , a control unit  12 , a crushing and cooking device  131 , a feeding mechanism  132 , a discharging mechanism  133 , a crushing cutter  134  and a motor  135  for driving the crushing cutter  134  to rotate. The feeding mechanism  132  and the discharging mechanism  133  are communicated with the crushing and cooking device  131 , respectively. The crushing cutter  134  is located in the crushing and cooking device  131 . The crushing cutter  134  stirs the material and water in the crushing and cooking device  131  such that the material is crushed and cooked into soybean milk. The motor  135  or the crushing and cooking device  131  is mounted on the base  11 . 
         [0061]    The base  11  is substantially of a “U” shape, and includes a pedestal  111 , a top plate  112  arranged opposite to the pedestal  111  and a supporting arm  113  connecting the top plate  112  and the pedestal  111 . The top plate  112  is provided with a through hole  1121  such that the motor  135 , the feeding mechanism  132  and the like are exposed outside the through hole  1121 . 
         [0062]    The crushing and cooking device  131  is a closed container or a substantially closed container provided around the crushing cutter  134  in a three-dimensional space. The peripheral wall of the crushing and cooking device  131  is arranged adjacent to the crushing cutter  134  in the three-dimensional space. In the present embodiment, the crushing and cooking device  131  is substantially a hollow sphere, the inner surface of the peripheral wall of which is configured to be a streamline shape arc surface. Since the crushing and cooking device  131  is closed or is substantially closed, noise transmitted to the external of the crushing and cooking device  131  is greatly reduced during the operating process of the crushing cutter  134  in the crushing and cooking device, which thereby can reduce the noise. Moreover, the closed or substantially closed structure can also enhance circulating pressure of the material and water in the crushing and cooking device  131 , which thereby facilitates the crushing of the material. A mounting portion  1311  is provided on the peripheral wall of the crushing and cooking device  131 , the mounting portion  1311  is provided with a through hole, through which a shaft of the motor  135  is protruded into the crushing and cooking device  131 , and the motor  135  is fixedly connected to the mounting portion  1311  via bolts in a vertical manner. In the present embodiment, the inner surface of the crushing and cooking device  131  is coated with a non-stick material such that it is not easy for the soybean milk to adhere to the inner surface. In the present application, the crushing and cooking device is configured to have a volume of 50-1000 milliliters, which not only ensures a normal soybean milk requirement but also can cook the soybean milk as soon as possible such that the cooked soybean milk complies with the requirements of the food safety. The soybean milk maker according to the present application can finish the making of soybean milk within five minutes. If the volume of the crushing and cooking device is smaller than 50 milliliters, soybean milk made by the soybean milk maker is insufficient for a single person, thereby the utility of the soybean milk maker is low; if the volume of the crushing and cooking device is larger than 1000 milliliters, heat is dissipated too rapidly during the crushing and cooking process, it is difficult to provide a crushing cutter and a motor matching with the crushing and cooking device, and the time for the crushing and the cooking is long, which therefore is uneconomical. 
         [0063]    In the present embodiment, the volume of the crushing and cooking device is 300 milliliters. 
         [0064]    The feeding mechanism  132  includes a bean feeding assembly  136  for feeding beans into the crushing and cooking device  131  and a water feeding assembly  137  for injecting water into the crushing and cooking device  131  (as shown in  FIG. 1 ).

One end of the bean feeding passage  1362  is communicated with the bin  1361 , and the other end thereof is communicated with the crushing and cooking device  131 . The bin  1361  is corresponded to the bean feeding passage  1362  and is mounted to the peripheral wall of the crushing and cooking device  131  via screws. The bean feeding passage  1362  is provided with a bean feeding controller  1363  for controlling the opening and closing of the bean feeding passage  1362 . The bean feeding controller  1363  includes a driving portion  1364 , a connecting rod  1365  and a baffle plate  1366 . The baffle plate  1366  is rotatably mounted in the bean feeding passage  1362 , and the connecting rod  1365  connects the driving portion  1364  with the baffle plate  1366 . 
         [0066]    The water feeding assembly  137  includes a water tank  1371 , a water inlet tube  1373  and a water feeding passage provided on and extended through the peripheral wall of the crushing and cooking device  131 . In the present embodiment, the water feeding passage and the bean feeding passage are integrated into one passage. One end of the water inlet tube  1373  is communicated with the water tank  1371 , and the other end thereof is communicated with the water feeding passage. The water inlet tube  1373  is provided with a check valve  1374  to prevent water from flowing back to the water tank  1371 . The bean feeding controller  1363  is electrically connected to the control unit  12 . Further, a sealing assembly is provided on the inner surface of the peripheral wall of the crushing and cooking device  131  at a position corresponding to the bean feeding passage  1362  for sealing the bean feeding passage  1362 . In the present embodiment, the sealing assembly is a soft rubber  1313 , one end of which is connected to the inner surface of the peripheral wall of the crushing and cooking device  131 . During the making of soybean milk, the soft rubber  1313  is adhered to the inner surface of the peripheral wall of the crushing and cooking device  131  under the impact of water flow, sealing the bean feeding passage  1362  to thereby preventing the material from entering the bean feeding passage  1362  during the making of soybean milk. 
         [0067]    The discharging mechanism  133  includes a discharging passage  1331  and a discharging controller  1332  for controlling the discharging of the seriflux. The discharging passage  1331  is provided on and extended through the peripheral wall of the crushing and cooking device  131  corresponding to a boiling container  14 . The discharging controller  1332  is a control valve including a valve body  1333 , a valve core  1334 , a connecting body  1335  and an operating portion  1336 . The valve body  1333  is corresponded to the discharging passage  1331  and is fixedly connected to the peripheral wall of the crushing and cooking device  131 . The valve core  1334  is rotatably mounted in the valve body  1333 . The operating portion  1336  is mounted to the valve body  131  via a connecting seat  1337 , and one end of the operating portion  1336  is connected to the valve core  1334  via the connecting body  1335  for driving the valve core  1334  to rotate, and the other end thereof is electrically connected to the control unit  12 . It is to be understood that the valve body  1333  may be integrated with or detachably connected with the crushing and cooking device  14 . 
         [0068]    The crushing cutter  134  is mounted to the end of the shaft of the motor  135 , and includes at least one blade which can pump the seriflux. In the present embodiment, the distance between the end of the blade of the crushing cutter  134  and the inner wall of the crushing and cooking device  131  within the rotation plane of the crushing cutter  134  is smaller than the radius of the crushing cutter  134 . In this way, the material can be forced to pass through the interspace between the crushing cutter  134  and the crushing and cooking device  131  to thereby be better guided to the crushing cutter  134  for being crushed. Further, the motor has a rated speed of 6000-50000 r/min, which is sufficient to ensure the efficiency of heat produced by friction. The efficiency of heat produced by friction is low if the rated speed is too low. However, it is unsafe to the user if the rated speed is too high, besides it is also noisy if the rated speed is too high. 
         [0069]    Further, the ratio of the diameter of the crushing cutter  134  to a diameter of a sphere having a volume equal to that of the crushing and cooking device  131  may be further defined to be 1:3 to 1:1, which not only can ensure a smooth circulation of the material but also can effectively define the material to be adjacent to the crushing cutter  134 , and thus the crushing effect of the crushing cutter  134  is enhanced. It is difficult to mount the crushing cutter  134  in the crushing and cooking device  131  if the ratio of the radius of the crushing cutter  134  to the radius of the sphere having the volume equal to that of the crushing and cooking device  131  is larger than 1:1; and if the ratio of the radius of the crushing cutter  134  to the radius of the sphere having the volume equal to that of the crushing and cooking device  131  is smaller than 1:3, the material can not be well defined to be adjacent to the crushing cutter  134  by the crushing and cooking device  131  since the crushing and cooking device  131  is too large relative to the crushing cutter  134 , therefore the efficiency of the crushing and cooking is reduced. In the present embodiment, it is desirable if the ratio of the radius of the crushing cutter  134  to the radius of the sphere having the volume equal to that of the crushing and cooking device  131  is 1:2. 
         [0070]    Where assembling the soybean milk maker  10 , firstly, the mounting portion  1311  of the crushing and cooking device  131  is fixedly connected to the top plate  112  of the base  11  via bolts; then the motor  135  is mounted to the mounting portion  1311 ; subsequently, the bin  1361  is mounted to the crushing and cooking device  131 , and then the water tank  1371  is communicated with the water feeding passage via the water inlet tube  1373 ; finally, the discharging controller  1332  is mounted to the crushing and cooking device  131 . 
         [0071]    Reference is made to  FIG. 3 . Where making soybean milk with the soybean milk maker  10 , firstly, the bean feeding controller  1363  is actuated by the control unit  12  such that beans for making soybean milk are all fed into the crushing and cooking device  131  through the bean feeding passage  1362 . Then the water for making soybean milk is partly injected into the crushing and cooking device  131  through the water inlet tube  1373 . Meanwhile, the motor  135  is actuated to drive the crushing cutter  134  to rotate in the crushing and cooking device  131  such that the material is crushed and is made into high concentration soybean milk. Since the soybean milk has a high concentration and the material is forced, by the crushing and cooking device  131 , to be adjacent to the crushing cutter, friction forces among the high concentration soybean milk, the crushing cutter  134  and crushing and cooking device  131  are large, causing the temperature thereof being increased until the high concentration soybean milk is fully cooked. Then, the discharging passage  1331  is opened by the control unit  12  to discharge the cooked high concentration soybean milk into a container (such as a cup). Next, the remained part of the water for making soybean milk is injected into the crushing and cooking device  131  such that the residual soybean milk adhered to the inner surface of the peripheral wall of the crushing and cooking device  131  is blended with the water, thereby the mixture is discharged, through the discharging passage  1331 , into the container and is blended with the soybean milk previously discharged into the container. 
         [0072]    In the present embodiment, where making soybean milk, in a case that the ratio of the weight of the material to the weight of the water is 1:10 to 2:1, a high concentration seriflux or paste can be made after the material is mingled with the water in the crushing and cooking device  131  and is crushed by the crushing cutter  134 , therefore the seriflux or paste, the crushing cutter  134  and the crushing and cooking device  131  can rub against one another more effectively such that the temperature can be increased by the frictions therebetween. If the ratio of the weight of the material to the weight of the water is smaller than 1:10, the concentration of the seriflux or paste made after the material is mingled with the water in the crushing and cooking device  131  and is crushed by the crushing cutter  134  is too low, therefore the friction forces among the seriflux or paste, the crushing cutter  134  and the crushing and cooking device  131  are small, and thus they can not rub effectively with one another to increase the temperature; if the ratio of the weigh of the material to the weight of the water is larger than 2:1, the concentration of the seriflux or paste made after the material is mingled with the water in the crushing and cooking device  131  and is crushed by the crushing cutter  134  is too high, the seriflux or paste may be condensed on the crushing cutter  134  or the crushing and cooking device  131 , and the seriflux or paste can not be evenly heated. In the present embodiment, it is desirable if the ratio of the weight of the material to the weight of the water is 1:3. Moreover, the temperature can also be effectively increased by frictions among the seriflux or paste, the crushing cutter and the crushing and cooking device  131  if the ratio of the volume of the mixture of the material and the water to the volume of the crushing and cooking device  131  is ranged from 1:2 to 1:1. The material and the water will overflow the crushing and cooking device  131  if the ratio of the volume of the mixture of the material and the water to the volume of the crushing and cooking device  131  is larger than 1:1; and friction forces among the seriflux or paste, the crushing cutter  134  and the crushing and cooking device  131  will be reduced if the ratio of the volume of the mixture of the material and the water to the volume of the crushing and cooking device  131  is smaller than 1:2. In the present embodiment, it is desirable if the ratio of the volume of the mixture of the material and the water to the volume of the crushing and cooking device  131  is 1:1.5. 
         [0073]    Where cleaning the soybean milk maker  10 , firstly, water is injected into the crushing and cooking device  131 ; the motor  135  is actuated to drive the crushing cutter  134  to rotate, the crushing cutter  134  in turn drives the water to rotate in the crushing and cooking device  131 , washing the shaft of the motor, the inner surface of the peripheral wall of the crushing and cooking device  131 , the bean feeding passage  1362  and so on. In this way, the soybean milk maker is automatically cleaned. 
         [0074]    The soybean milk maker  10  employs the crushing and cooking device  131  having the unique configuration, thus the time for making soybean milk is greatly reduced, the soybean milk maker  10  can finish the making of soybean milk within ten minutes, which soybean milk maker steps into an era of making soybean milk quickly, and solves the problem that a long period is spent by the prior soybean milk maker for making soybean milk, which problem has puzzled the industry for a long time. 
         [0075]    During the period in which the material for making soybean milk is stirred by the crushing cutter  134  of the soybean milk maker  10  and is crushed to make soybean milk in the crushing and cooking device  131 , the high concentration soybean milk is also cooked. In this way, the crushing of the material and the cooking of the material are performed simultaneously, thus the soybean milk is also cooked. 
         [0076]    It can be understood that the inner surface of the crushing and cooking device may be further provided with ribs for interfering with the flow, to thereby facilitate rebounding of the material to the crushing cutter. 
         [0077]    It can be understood that the high concentration soybean milk may also be blended with water in the crushing and cooking device, then soybean milk got by the blending process is discharged into the container; and the motor is rotated to stir the soybean milk during the blending process. 
         [0078]    It can be understood that the process of blending the high concentration soybean milk with water may also be performed partly in the crushing and cooking device and partly in the container. 
         [0079]    It can be understood that the sealing assembly may also have other valve type sealing structures.

The inner layer  4312  is superposed to the thermal insulation layer  4311 , forming a closed crushing chamber. Since the crushing and cooking device  431  is provided with a thermal insulation layer, noise generated during the crushing process can be effectively reduced, and the crushing chamber is isolated from the external environment, thereby influence of the external environment on the process of making soybean milk is reduced. 
         [0083]    It can be understood that the crushing and cooking device may include a plurality of thermal insulation layers. 
         [0084]    It can be understood that a vacuum layer may be provided between the inner layer and the thermal insulation layer to further isolate the crushing chamber from the external environment.

In the present embodiment, the cutter shaft  14  is the shaft of the motor  16 , which passes through the wall of the crushing and cooking device  151  and extends into the crushing and cooking device  151 . The minimum distance d 1  between the crushing cutter  13  and the bottom of the crushing and cooking device  151  is 1-30 millimeters, therefore the crushing cutter  15  can be embedded in the material, which increases the probability that the crushing cutter  15  is in collision with the material. If the minimum distance d 1  between the crushing cutter  15  and the bottom of the crushing and cooking device  151  is smaller than 1 millimeter, the material may be stuck between the crushing cutter  15  and the crushing and cooking device  151 , which increases the difficulty of the cleaning. If the minimum distance d 1  between the crushing cutter  15  and the crushing and cooking device  151  is larger than 30 millimeters, it is difficult to stir the material at the bottom of the crushing and cooking device  151 , and there may occur that the crushing cutter can not catch the material at the bottom at all, which will waste more electrical energy. In the present embodiment, the minimum distance d 1  between the crushing cutter  15  and the bottom of the crushing and cooking device  151  is 10 millimeters. 
         [0113]    Where the soybean milk maker  10  is used to make soybean milk, firstly, the cover body  152  is opened, at this time, the material can be easily put into the crushing and cooking device  151 ; then the cover body  152  is closed to close the opening  1511 , at this time, power source may be switched on such that the motor  16  is controlled by the control unit  12  to perform the making of the soybean milk. 
         [0114]    Where cleaning the soybean milk maker  10 , the crushing cutter  15  is driven by the motor  16  to rotate, the crushing cutter  15  stirs water to rotate in the crushing and cooking device  15 , washing the cutter shaft  14  and the inner peripheral wall of the crushing and cooking device  15 , thereby realizing an automatic cleaning of the soybean milk maker  10 . Of course, the soybean milk maker may also be cleaned manually. That is, the cleaning may be performed by the user manually after the cover body  152  is opened. Therefore, many choices are provided in use and it is more convenient. 
         [0115]    In the soybean milk maker  10  according to the present application, the crushing and cooking device  15  that can be opened and closed is employed. Therefore the user can open the cover body  152  of the crushing and cooking device  15  to add the material into the crushing and cooking device  151  where using the soybean milk maker  10 . In this way, the feeding mechanism and/or the water feeding mechanism may be eliminated from the soybean milk maker  10 , therefore the structure of the soybean milk maker is more compact and it is applicable to be used in household, besides the cost of the whole maker is also reduced. Moreover, the crushing and cooking device  151  has a certain volume, where being added with the material manually, the problem of bad crushing and cooking due to adding too much material can be effectively avoided, which has a “Fool-Proof” effect and can ensure the quality of soybean milk. Further, the user can also open the cover body  152  anytime anywhere to replace the crushing cutter  15  according to various materials to be crushed and cooked. 
         [0116]    The motor  16  of the soybean milk maker  10  according to the present application is horizontally provided on the base  11  and is located at a side of the crushing and cooking device  151 , the center of gravity of the whole soybean milk maker is lowered, the stability of the whole maker is improved, and the probability that the seriflux or water enters the motor  16  and the control unit  12  during a manual operation is reduced, thus the making of the soybean milk is more safe and reliable. Further, the crushing cutter  13  is brought into direct contact with the material and is driven by the motor  16  to rotate at a high speed to thereby crush the material. Thereby the crushing efficiency is improved. 
         [0117]    In the soybean milk maker  10  according to the present application, the crushing and cooking device  15  that can be opened and closed is employed. Therefore the user can open the cover body  152  of the crushing and cooking device  15  to add the material into the crushing and cooking device  152 . In this way, the feeding mechanism and/or the water feeding mechanism may be eliminated from the soybean milk maker  10 , therefore the structure of the soybean milk maker is more compact and it is applicable to be used in household, besides the cost of the whole maker is also reduced. Moreover, the crushing and cooking device  151  has a certain volume, where being added with the material manually, the problem of bad crushing and cooking due to adding too much material can be effectively avoided, which has a “Fool-Proof” effect and can ensure the quality of soybean milk. Further, the user can also open the cover body  152  anytime anywhere to replace the crushing cutter  13  according to various materials to be crushed and cooked. 
         [0118]    It can be understood that the speed and rotation direction of the motor may be switched where performing the crushing or the washing to increase the crushing effect or the cleaning effect. 
         [0119]    It can be understood that the rapid soybean milk making soybean milk maker  10  not only can be used to make soybean milk, but also can be used to make other food that needs to be crushed and heated such as fruit and vegetable juice, sesame paste or the like. 
         [0120]    It can be understood that, in the present soybean milk maker, heat generated by frictions includes not only heat generated by friction of the seriflux or paste itself, friction between the seriflux or paste and the crushing cutter  13 , and friction between the seriflux or paste and the crushing and cooking device  15 , heat generated by frictions among elements in the crushing and cooking device  13  can also be used to heat the seriflux or paste, which should also fall within the protection scope of the present application.
