Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a mixer for use in general households.

Conventional technology In recent years, mixers have become mainstream because they can be used to grind and mix vegetables and fruits to make juices, soups, etc., as well as desserts such as ice cream and mousse, and drinks such as shakes. There is.

Conventionally, this type of mixer has been constructed as shown in FIGS. 7 and 8. The configuration will be explained below.

As shown in FIG. 7, a rotary shaft 24 to which a long sword-shaped cutter 23 is attached is rotatably supported at the center of the bottom of a mixer tip 22 having a lid 21. As shown in FIG.

This rotating shaft 24 is connected via couplings 25, 26 to
It is connected to an electric motor 28 within the mixer body 27.

The inner wall of the mixer tip 22 is provided with a plurality of triangular lips 3 in order to circulate the cooking material 29 to improve the agitation performance and thereby enable the cooking material 29 to be finely cut.
0 is set. Further, as shown in FIG. 8, a container 33 having a rotating body 32 rotatably supported via a coupling 31 that can be attached to the mixer main body 27 in exchange for the mixer tip 22 is provided as a separate part. There is.

In the above configuration, when the electric motor 28 is energized, the coupling ring 26 rotates and the coupling 25 connects the rotating shaft 24 to the rotating shaft 24.
The cutter 23 attached to the rotates (approximately 1010
000 rpm, the cooking material 29 in the mixer tap 21 is crushed to produce juice or the like.

Furthermore, when the container 33 is attached to the mixer main body 27 in place of the mixer tip 21, the rotating body 32 similarly rotates via the coupling 31, and ice cream or the like can be whipped.

Problems to be Solved by the Invention However, according to the above configuration, when making a drink that uses a large amount of hard cooking ingredients such as ice, such as shakes and frozen cocktails, the high speed rotation of the cutter 23 causes the cooking ingredients 29 to Cutter 23, rib 30, and lid body 2
It is crushed while colliding with 1 etc., but is it a relatively large and hard cooking material such as ice? 9, the number of collisions with the inner wall of the mixer tip 22 and the ribs 30 increases before the particles are crushed into fine pieces. In addition, since the cooking ingredients 29 remain in their original shape immediately after startup, the vibrations of the mixer top 22 due to collisions will increase and cause the mixer top 22 to fall over, the lid 21 to come off during cooking and the ingredients to be cooked to be thrown out, and grinding noises. It had problems such as getting too big. Also, when cooking ice cream etc., if you use the mixer tip 22,
Since the cutter 23 is rotated continuously at a constant speed, it takes a long time to whip ice cream, for example, to cause changes in the ingredients. It is very inconvenient in terms of ease of use and storage, as it has to be replaced and cannot be used for cooking in the same container.

Therefore, the present invention solves the above problems.Even if a large amount of comparatively hard and large cooking ingredients such as ice are thrown in, the mixer top will not fall over or the lid will come off, and the noise is small and there is no danger. The aim is to provide a mixer that can be used with peace of mind, and is also easy to use and can grind juices and whip ice cream without having to replace the mixer tip with a separate container. The purpose is to provide.

Means for Solving the Problems In order to solve the above problems, the first means of the present invention is to provide a mixer main body with a built-in electric motor, a mixer top placed on the mixer main body, and a bottom part of the mixer top. This mixer is equipped with a cutter rotatably provided in the mixer, and a control means that energizes the motor intermittently and continuously after a predetermined period of time.

Moreover, in order to solve the above-mentioned problem, the second means of the present invention is a mixer in which the mixer body is provided with an operating means for changing the setting of the operating time in intermittent operation.

Effect According to the first means, even when a large amount of relatively hard and large ingredients such as ice are thrown in, the electric motor is energized intermittently, and after the cooking ingredients have been roughly pulverized, the electric motor is continuously energized. Therefore, the cooking ingredients are smaller than when the mixer tip is continuously energized from the beginning, so the impact on the mixer tip can be reduced, and it is possible to prevent it from tipping over or the lid coming off.

According to the second means, since the mixer body is provided with an operating means that can change the operating time setting in intermittent operation, it is possible to change the rotation of the cutter to foam the material and entrain air bubbles. Therefore, ice cream or the like can be whipped without using a separate container.

EXAMPLE A first example of the present invention will be described below with reference to FIGS. 1 to 3.

At the center of the bottom of a mixer tip 2 having a lid 1, a rotary shaft 4 to which a long sword-shaped cutter 3 is attached is rotatably supported. The rotating shaft 4 is connected to an electric motor 8 in the mixer main body 7 via couplings 5 and 6.

A control device (control means) 9 is disposed on one side of the mixer body 7 to control the electric motor 8 to be energized intermittently and to be continuously energized after a predetermined period of time. In addition, a plurality of triangular ribs 11 are provided on the inner wall of the mixer tip 2 to circulate the cooking material 10 to improve stirring performance and to enable the cooking material 10 to be finely cut.

Next, the operation of the above configuration will be explained based on FIGS. 2 and 3. FIG. 2 is a characteristic diagram showing the relationship between the voltage applied to the motor 8 and time when the mixer main body 7 is intermittently energized. In FIG. 2, tl is on time and t2 is off time, and both tl and t2 can be usually set in the range of 0 seconds to several seconds. Furthermore, assuming that the predetermined time until continuous energization starts is T, the relationship between the rotational speed of the electric motor 8 and time at this time is shown in FIG. In FIG. 3, the solid line A shows the case where the energization changes from intermittent energization to continuous energization after T seconds, and the broken line B shows the case where energization is carried out continuously from the time of startup.

When the electric motor 8 is energized by the control device 9, the coupling 6 rotates, and the rotation shaft 4 is connected via the coupling 5.
The cooking ingredients in the mixer tip 2 are pulverized by the rotation of the cutter 3 attached to the mixer tip, but for T seconds after startup, as shown in Figure 3, the power is intermittently energized, so it is much slower than continuous energization. It has a low rotation speed and rotates slowly.

Therefore, even when a large amount of relatively hard and large cooking material IO is thrown in, it can be roughly pulverized in T seconds without giving a large impact to the mixer tip 2, lip 11, lid 1, etc. Thereafter, the current is continuously energized, but since the cooking material in the mixer top 2 is slightly smaller than at the time of starting, the impact caused by collision with the inner wall of the mixer top 2, the ribs 11, and the lid 1 is reduced. As a result, the mixer tip 2 does not fall over due to vibrations, the lid 1 does not come off, etc., and therefore the mixer tip 2 can be used safely without any risk of low noise.

Next, a second embodiment will be explained based on FIGS. 4 to 6.

In this embodiment, the intermittent operation time setting for the mixer main body 7 in FIG. 1 can be changed.

For example, an operation switch (operation means) 12 having three settings of C, D, and E is provided, and this operation switch 1
The time setting can be changed using the dial No. 2. In other words, with just the mixer tip 2, you can create anything from pulverizing something like juice to whipping ice cream.

Next, the operation of the configuration of this embodiment will be explained in FIGS. 5 and 6.
This will be explained based on the diagram. The three settings of the operation switch 12 are C: continuous energization, D = the same setting as in the first embodiment, and E: intermittent energization as shown in FIG. 5 (t3 is on time, t4 is off time). . C is a conventional mixer, which is used to make ordinary juices and the like. Further, as shown in the first embodiment, D is used when making juice using a relatively hard and large cooking material such as ice. E is used for cooking ingredients that require whipping, such as ice cream.
When foaming, it is necessary to stir the material or cause a change in the flow of the material to incorporate air bubbles.

FIG. 6 is a characteristic diagram showing the relationship between the rotation speed of the electric motor 8 and time when the operation switch 12 is set to E. The electric motor 8 is rotated intermittently to accelerate and decelerate the rotation of the cutter 3, and the mixer tip 2 By changing the flow of the material in the mixer and incorporating more air bubbles, fine, high-quality foaming can be achieved in a short time by using the same mixer tip 2 and cutter 3 that create juices, etc. be able to.

In the second embodiment, the operation switch 12 has three settings, but more time settings can be provided by changing the times 13 and 14 as necessary.

Effects of the Invention As described above, according to the configuration of the present invention, the electric motor in the mixer main body is energized intermittently to roughly crush the cooking ingredients, and then energized continuously, so that the impact on the mixer tip is reduced. Therefore, there is no possibility of the tip falling over due to vibration or the lid coming off, and it is possible to provide a mixer that can be used safely without any risk of low noise.

According to another aspect of the present invention, since the mixer body is provided with an operation means that can change the setting of the operating time in intermittent operation, the rotation of the cutter is changed, so that it is possible to make juice etc. at the same time. With the mixer tip and cutter, it is possible to provide a mixer that can whip fine, high-quality foam in a short time.
