FIELD OF THE INVENTION The present invention relates generally to household bean milk and bean curd makers, and more particularly, to a reinforcing device for household bean milk and bean curd makers, which reinforces a structure for fastening a drive motor to a main body using a bracket, thus reducing vibration and noise, and which is constructed such that a body cap extends to a predetermined length, thus preventing a lower portion of the main body from being thermally deformed, and thereby reducing vibration and noise.
DESCRIPTION OF THE RELATED ART The process of making bean milk and bean curd using a traditional method is as follows.
First, beans are washed, and the washed beans are soaked in water for many hours. The soaked beans are grinded by a mill or a blender to obtain an extract of beans. The extract of beans is strained through a sieve or closely perforated cloth to be divided into bean curd dregs and an extract of protein.
Next, only the extract of protein is put into a vessel, such as a pot, and is boiled. At this time, the extract of protein may boil over. Thus, in order to prevent the extract of protein from boiling over, heating power must be carefully regulated by a user. After the extract of protein is boiled for a predetermined period, additives, including sugar, salt, and others, are added to the extract of protein into the bean milk.
Meanwhile, when it has been several minutes since a coagulant, such as calcium sulphate, was added to the extract of protein boiled for the predetermined period, and the extract of protein with the coagulant was stirred, watery bean curd is made. Further, when the watery bean curd is pressed in a frame to have a predetermined shape, the bean curd is made.
However, the conventional method of making bean milk and bean curd has a problem in that several processes are individually executed, thus it is inconvenient and complicated to make the bean milk and the bean curd, and it takes longer time to make the bean milk and the bean curd, and thereby the conventional method is inefficient.
In order to solve the problem, there have been proposed various devices for easily and conveniently making bean milk and bean curd at home. For example, there are Korean Patent No. 99-225772, Korean Patent No. 2000-228659, Korean U.M. Registration No. 158856, Korean U.M. Registration No. 250843, etc. The Korean Patent No. 99-225772 was published on Oct. 15, 1999, and is titled �household bean curd maker�. The Korean Patent No. 2000-228659 was published on Mar. 15, 2000, and is titled �household bean curd maker�. The Korean U.M. Registration No. 158856 was registered on Jul. 16, 1999, and is titled �household bean curd maker�. The Korean U.M. Registration No. 250843 was registered on Oct. 5, 2001, and is titled �household bean curd maker with fixed-type blade unit�.
FIG. 1 is a sectional view of the conventional household bean milk and bean curd maker. As shown in FIG. 1, the is conventional household bean milk and bean curd maker includes a housing 1 which has a cavity to contain water therein. A main body 2 is provided on an upper portion of the housing 1 to open or close the housing 1, like a lid. A drive motor 3 is installed in a predetermined portion of the main body 2, and generates rotating power when electricity is applied to the drive motor 3. A drive shaft 4 transmits the rotating power from the drive motor 3. A cutting blade 5 is provided at an end of the drive shaft 4. A heater 6 downwardly extends from the main body 2, and generates heat when electricity is applied to the heater 6, thus heating an interior of the housing 1. A temperature sensing bar 7 detects the temperature of the interior of the housing 1. A filter net 9 is detachably mounted to a predetermined portion of the main body 2, and contains beans therein. Further, the household bean milk and bean curd maker also includes a body cap 8 to protect a lower portion of the main body 2 and a part of the drive shaft 4.
The conventional household bean milk and bean curd maker which is constructed as described above is operated as follows.
First, a user puts water into the housing 1. The beans are put into the filter net 9 which is detached from the main body 2, and then the filter net 9 having the beans is assembled with the body cap 8 which is mounted to the lower portion of the main body 2. Thereafter, the main body 2 is placed on the upper portion of the housing 1 so that the filter net 9 is put into the housing 1.
Next, when a power switch (not shown) is turned on to apply electricity to the household bean milk and bean curd maker, a control unit (not shown) outputs a control signal to operate the heater 6 and the temperature sensing bar 7. At this time, a primary heating process is executed while maintaining a predetermined temperature, for a predetermined period.
When the primary heating process has been completed, the control unit outputs a control signal to operate the drive motor 3. As the drive motor 3 is operated, the beans contained in the filter net 9 are grinded by the cutting blade 5 provided at the end of the drive shaft 4. While the beans are grinded, the turbulence of water contained in the housing 1 is caused by a rotation of the cutting blade 5. By the turbulence, bean grains which are finely grinded by the cutting blade 5 come out of the filter net 9. Thus, the beans grinded by the cutting blade 5 are divided into bean-curd dregs which remain in the filter net 9, and the extract of protein which flows out the filter net 9.
Thereafter, the control unit outputs control signals to operate the heater 6 and the temperature sensing bar 7. At this time, a secondary heating process is executed while maintaining a predetermined temperature, for a predetermined period. Through the above-mentioned process, bean milk is obtained.
When the user desires to make bean curd, the user takes the heated extract of protein out of the housing 1. Next, the coagulant is added to the heated extract of protein so as to coagulate the extract of protein. Thereafter, the coagulated protein is pressed in the frame to produce the bean curd.
However, the conventional household bean milk and bean curd maker has a problem that a force to fasten the drive motor 3 to the main body 2 is relatively weak, thus causing vibration and noise. The conventional household bean milk and bean curd maker has another problem that the body cap 8 is short, thus a part of the lower portion of the main body 2 which is not covered with the body cap 8 may be thermally deformed, and thereby causing vibration and noise.
SUMMARY OF THE INVENTION Accordingly, the present invention has been made keeping in mind the above problems occurring in the prior art, and an aspect of the present invention is to provide a reinforcing device for household bean milk and bean curd makers, which increases a force to fasten a drive motor to a main body using a bracket, thus reducing vibration and noise.
Another aspect of the present invention is to provide a reinforcing device for household bean milk and bean curd makers, which is constructed such that a body cap extends to a predetermined length, thus preventing a lower portion of the main body from being thermally deformed, and thereby reducing vibration and noise.
