CONSTITUTION:A driving motor 2 stored in a main body 1, a cup 9 mounted on the main body 1, and cutters 5 located in the cup 9, connected to the motor 2 via connectors 4, 7, and fixed to a cutter shaft 3 supported by a cup base 8 are provided, and a partition body 10 is horizontally provided in the cup 9.

Description

Description: [0001] The present invention relates to a household electric cooking machine such as a mixer. 2. Description of the Related Art A conventional electric cooking machine will be explained below with reference to FIG. Shaft 3 of motor 2 included in main body 1
A connector 4 is fixed to the shaft 6 of the cutter 5, and a connector 7 is fixed to the shaft 6 of a cutter 5 for crushing and cutting materials. When the cup stand 8 is placed on the main body 1, the connectors 4 and 7 are fitted together, and the cutter 5 can be driven by the motor 2. With the above-described structure, the material such as fruit placed inside the cup 9 is circulated within the cup 9 while being cut by the rotating cutter 5. In this way, the material becomes finely divided and juice is produced. [0004] However, the conventional structure described above has a problem in that periodic pulsating noise is generated. In other words, the material in the cup 9 moves upward along the inner surface of the cup while being cut by the cutter 5 rotating at high speed. This movement reduces the amount of material remaining below the cup 9, and the amount of material moving from the bottom to the top becomes unbalanced with the amount of material circulating from the top to the center of the bottom. This imbalance causes periodic pulsating noise. Another problem is that the cutting efficiency is poor because the material has a large vertical flow. [0005] The present invention solves the problems of the conventional structure described above, and aims to provide an electric cooking machine that can suppress periodic pulsation noise and improve cutting efficiency. [Means for Solving the Problems] The means of the present invention for achieving this object includes a driving motor included in a main body, a cup placed on the main body, and a motor located inside the cup. , a cutter driven by the motor, and a horizontal partition provided above the cutter inside the cup. [0007] The material cut by the cutter and moving upward along the inner surface of the cup collides with a partition provided inside the cup. The material is thus forced to circulate downwardly and centrally. In other words, due to the forced circulation effect of this partition, the amount of movement from the bottom of the cup to the top and the amount of circulation from the top to the center of the bottom become balanced. In this way, periodic pulsating noise can be suppressed. In addition, the forced circulation speeds up the period of vertical flow of the material, increases the number of times the material hits the cutter per unit time, and allows efficient cutting. [Embodiment] The configuration of an embodiment of the present invention will be explained below with reference to FIG.
・Explanation will be given based on FIGS. 2 and 3. In the figure, 1 is a main body, and 2 is a driving motor, which is supported within the main body 1. Reference numeral 3 designates its rotating shaft, which is held by a bracket 11 and bearings 12 and 13 fixed to the main body 1 which also serves as a bracket. 4 is below the connector fixed to the rotating shaft 3. Also, 9 is a cup for storing ingredients such as fruits, and the seal 14
It is screwed onto a cup stand 8 formed on the main body 1 via a screw. Reference numeral 5 denotes a cutter for crushing and cutting materials such as fruits, and is fixed to one end of a cutter shaft 6 supported by a bearing 15 fixed to a cup stand 8. A connector 7 is fixed to the other end of the cutter shaft 6 and is fitted with the lower connector 4. Further, above the cutter 5 in the cup 9, a partition body 10, which is the key point of this embodiment, is provided in the horizontal direction. As shown in FIG. 2(a), the partition body 10 has a concave portion 17 on its outer periphery so as to fit into a rib 16 of the cup 9. In other words, when the partition body 10 is fitted into the cup 9, the ribs 16 and the recesses 17
Due to this action, the partition body 10 is prevented from rotating. In addition, the shape of the partition body 10 is not limited to the disk shape shown in FIG. 2(a), but also the shape of the partition body 10, as shown in FIG. A shape having an opening 18 in the center, a shape having a large number of holes 19 as shown in FIG. 2(c), etc. can be considered. In addition to the method shown in FIG. 2, methods shown in FIGS. 3(c) and 3(d) may also be considered as a method for fixing the partition body 10. In the fixing method shown in FIG. 3(c), a spring 21 is provided on the lid 20 that covers the top of the cup 9, and a partition body 10 is attached to this spring 21 to maintain a constant downward force. . Further, in the method shown in FIG. 3(d), a rod or screw 22, etc. is provided on the lid 20, and the partition body 1 is
0 at a constant height. 00
12] The operation of this embodiment will be explained below. First, the cup 9 is screwed onto the cup stand 8 via the seal 14 and placed on the main body 1. At this time, the upper connector 7 and the lower connector 4 are automatically fitted together. Next, materials such as fruits are put into the cup 9, and the partition body 10 is fitted into the cup 9. Thus motor 2
When driven, the material is crushed and cut by the cutter 5. At this time, the material is thrown in the circumferential direction by the cutter 5 rotating at high speed, and moves upwards of the cup along the inner surface of the cup. During this movement, the material collides with a partition 10 provided horizontally inside the cup 9. This collision forces the material to circulate downward to the center. As a result, the amount of movement of the material from the bottom to the top of the cup 9 and the amount of movement of the material circulating from the top to the center of the bottom are balanced even in a short period of time. Since the amount of movement of the material is balanced in this way, it is possible to suppress the periodic pulsating noise that was a problem in the conventional example. [0013] Also, the forced circulation speeds up the period of vertical flow of the material, increases the number of times the material is cut by the cutter 5 per unit time, and improves cutting efficiency. [0014] As described above, the present invention has a drive motor included in the main body, a cup placed on the main body, and a cutter located above the cutter 5 inside the cup. However, by providing a horizontal partition inside the cup, an electric cooking machine is realized which can suppress periodic pulsation noise and improve cutting efficiency.
