Description

Blender with UV sterilization and blow drying function {MIXER HAVING FUNCTION OF UV STERILIZING AND AIR-BLOW DRYING}

The present invention relates to a blender, and more particularly, to a blender capable of sterilizing and blowing drying inside a blade and a container by having a UV LED and a blower blade.

In general, a blender is commonly used to pulverize food and grind it into powder form, to prepare liquid juice, or to uniformly mix various ingredients. A conventional blender combines a container with a blade into a main body with a driving motor built into it, and the blade rotates as the driving motor is operated while the ingredients are put inside the container, so that the crushing or mixing of the ingredients is not possible. It is configured to be done. After the blender is operated, a lot of pulverized food ingredients are deposited on the inner wall of the container and the blade area. To remove this, water is usually poured into the container to wash. However, since the blade is provided on the bottom of the container, it is difficult to cleanly clean the vicinity of the blade due to the fear of the hand being cut. Accordingly, the inside of the container is contaminated due to food material debris remaining around the blade, and this contamination state accumulates, causing food poisoning and other various bacteria harmful to the human body to multiply, thereby threatening the health of the user. In addition, in the case of leaving without a separate drying operation after washing with water, bacterial propagation occurs vigorously due to residual moisture, and this also acts as a great threat.

On the other hand, in order to solve the above problems, the Korean Utility Model Registration No. 20-0443213 proposes an electric mixer having a sterilizing function by embedding an ultraviolet lamp. However, even according to the above registration utility model, since the ultraviolet lamp is disposed under the blade base, the blade disposed above the blade base and the inside of the container on the upper side do not have a substantially sterilizing effect and do not have a separate drying function. The fear of bacterial growth is still not resolved inside the blade and container.

Republic of Korea Utility Model Registration No. 20-0443213

The blade 240 is disposed inside the container 200, and the blade shaft 250 is coupled to the lower center of the blade 240. The blade shaft 250 acts as a rotation axis of the blade 240, and is coupled through the bottom surface of the container 200 as shown in FIG. 4 so that the upper end is coupled to the lower center of the blade 240 The lower end is coupled to the second coupler 280 to be described later. In addition, a packing 260 for sealing a penetrating portion of the bottom surface of the container 200 is fitted on the outer circumferential surface of the blade shaft 250. The packing 260 is configured in a diaphragm type having a diameter larger than the diameter of the bottom penetration portion of the container 200, a through hole is formed in the center so that the blade shaft 250 is penetrated, and the upper side is formed at the edge. A concave groove 262 to be viewed is formed. As the concave groove 262 is fitted with a locking hole 270 protruding from the bottom of the container 200, the packing 260 can be fixedly installed in the correct position without being separated.

The fixing cap 230 is coupled to the coupling rim 220 on the lower side of the container 200. The fixing cap 230 is for fixing and supporting the blade shaft 250 and the packing 260, and is configured in a generally short cylindrical shape, and a thread corresponding to the thread of the outer circumferential surface of the coupling rim 220 is formed on the upper inner circumferential surface. It is configured to be screwed to the coupling rim 220. In addition, a packing seating portion 232 on which the packing 260 is seated is protruded from the inner circumferential surface of the fixing cap 230 to the inside, and the blade shaft 250 is penetrated into the center of the fixing cap 230. do.

Meanwhile, a second coupler 280 is coupled to the lower end of the blade shaft 250.

The second concave-convex portion 284 is formed alternately with the above-described first concave-convex portion 146 and is engaged with each other, so that the first coupler 140 and the second coupler 280 are integrally rotatable. . Accordingly, when the driving motor is operated, the motor shaft 130 and the first coupler 140 coupled thereto are rotated, and the second coupler 280 coupled to the first coupler 140 and the blade coupled thereto The shaft 250 is rotated and finally the blade 240 is rotated.

As the fixing cap 230 is screwed to the coupling rim 220 on the lower side of the container 200, the blade shaft 250 and the packing 260 are fixed in place to prevent separation and separation, and thus the The blade 240 and the second coupler 280 coupled to the blade shaft 250 are firmly fixed and supported.

The container 200 has a handle 210 formed on one side so that the user can grip the container 200, the upper part is configured in an open shape, and the container lid 300 is detachably coupled to the upper opening. It is desirable. In addition, a measuring cup 310 may be coupled to the central portion of the container lid 300 to adjust the amount of food ingredients.

Through this configuration, as shown in Fig. 1, in a state in which the main body 100 and the container 200 are combined, put food materials to be crushed or mixed in the container 200, and close the container lid 300, and then the main body When the power of 100 is connected and the operation switch 120 is operated to operate the driving motor, the first coupler 140 and the second coupler 280 rotate as the motor shaft 130 of the driving motor rotates. And, while the blade shaft 250 and the blade 240 coupled to the second coupler 280 are rotated, a grinding or mixing operation of the food material is performed.

On the other hand, after the pulverization or mixing of the food ingredients is completed, as shown in FIG. 2, the container 200 and the container lid 300 are separated and washed with water to primarily remove food material debris from the inside. Then, as shown in FIG. 5, the container 200 is turned over and molded on the top of the main body 100 with the upper opening facing downward. Then, when the operation switch 120 is set to the sterilization and blowing drying position, the UV LED 160 disposed on the bottom surface of the container coupling groove 110 is turned on. The ultraviolet rays generated from the UV LED 160 are irradiated upward to directly sterilize the inside of the container 200 and the blade 240. At the same time, as the driving motor built in the main body 100 is operated, the first coupler 140 coupled to the motor shaft 130 rotates, and the blowing blade 148 formed outside the first coupler 140 ) Blows the wind upwards. Water on the inside of the container 200 and the blade 240 is dried by this wind. This sterilization and drying operation is preferably configured to be automatically stopped after being performed for a predetermined period of time. Meanwhile, as described above, a color LED 170 is additionally provided on the bottom surface of the container coupling groove 110, so that the color of the LED that emits light is changed according to the progress of the sterilization and drying operation so that the user can You can check the progress of the work with the naked eye. Since the container 200 is usually made of a transparent material so that the contents of the inside can be checked, when light of a specific color is emitted inside, it can be easily checked from the outside. For example, the red color LED 170 is turned on at the initial stage of the sterilization and drying operation, and the green color LED 170 is turned on when the sterilization and drying is almost completed, so that the user can easily grasp the progress.

In the above, specific embodiments of the present invention have been described. However, the spirit and scope of the present invention is not limited to these specific embodiments, and various modifications and variations are possible within the scope of not changing the subject matter of the present invention. Anyone who has it will understand.
