Description

[Detailed Description of the Invention] (b) Industrial field of application The present invention is a cooking device for foaming ingredients, and in particular, an ingredient for frothing ingredients such as fresh cream, milk, egg yolk and sugar to froth an ice cream dough. Relates to a suitable cooker.

(B) Conventional technology Conventionally, as this type of cooking device, a stirring device having a disk is rotated to foam a material such as egg white, etc.
It is known from Japanese Laid-Open Patent Publication No. 33065. This cooker does not have a mark to check the foaming state of the material, and because the material convects during operation, it is difficult to check the foaming state of the material, and the user stops the operation by intuition and confirms the foaming state. If the amount of foaming was insufficient, the product was restarted to foam the material.

In particular, when foaming materials such as fresh cream, milk, egg yolk, and sugar to produce an ice cream dough, unlike the case of foaming a single material such as egg white, it does not completely foam, but “6 to 7”. "Separation" (1.6 times the initial volume ~ 2.0
Although it is optimal to foam with a double volume increase, this optimum foaming state could not be easily confirmed.

In order to solve the above problems, as shown in FIG.
The step (d) for display is formed on the engaging part (b) with the rotating shaft (c) of (a), and the stirrer (a) is rotated into the disk (e) to be inserted into the container (f). It is possible to confirm the foaming state of the material by covering the stepped portion (d) with the material when the predetermined amount of the material is in the desired foaming state.

However, in this configuration, since the rotating shaft (c) is extended inside the container (f) through the sleeve (g) of the container (f), the outside of the engaging portion (b) of the stirring body (a) is The diameter is increased, and the peripheral speed of the outer peripheral portion of the engaging portion (b) is increased. Therefore, even if the foamed material in the desired foaming state reaches the height at which the stepped portion (d) is covered, the peripheral speed of the upper surface of the stepped portion (d) causes the material to fly outward and the desired foaming state. Even if it is in the state, there is a problem that the display step (d) is not covered.

(C) Problems to be solved by the present invention The present invention has been made in view of the above problems, and the operation is stopped in the foaming state of the material even when the agitator has a large engaging portion with the rotating shaft. An object is to provide a cooker that can be easily checked without doing.

(D) Means for Solving Problems In order to solve the above-mentioned object, the present invention has a built-in motor,
A base that projects the rotation shaft of the motor upward, a container that is placed on the base and that projects the rotation shaft inside through a sleeve, and a container that is mounted on the rotation shaft and rotates at the bottom of the container. A circular disc that rotates in proximity to the inner bottom of the container, and a ring shape that is integrally erected upward toward the upper side concentrically with the center of rotation of the circular disc. The ring-shaped display cylinder has a smaller diameter than the outer diameter of the disc and has a space from the center of the stirring body.

(E) Action According to the configuration of the present invention, a predetermined amount of material is put in the container,
When the stirrer is rotated, bubbling progresses while the air is mixed by the rotation of the disk around the display cylinder, and the volume increases.

And the material whose volume has increased until it covers the upper surface of the display tube is
The pulsation is caused to fly outward by the rotational force, and the pulsation of contacting the display cylinder again is repeated, the volume further increases, and the material passes over the display cylinder and flows into the space between the center of the stirring body and the display cylinder. At this time, it can be confirmed that the material is in a desired foaming state.

(F) Embodiment An embodiment of the present invention will be described in detail below with reference to FIGS. 1 and 2.

Is formed in a substantially L shape. (2) is a motor arranged in the housing portion (1a) of the base (1), screwed to a metal fixing plate (3) attached to the base (1), and its output shaft (2a ) Has a cooling fan (4)
And the small pulley (5) is installed. (6) is the fixed plate
A rotating shaft that is rotatably attached to (3) and a large pulley on the bottom.
(7) is attached and the upper part is projected from the mounting part (1b). (8) is a belt that is hung between the small pulley (5) and the large pulley (7), and transmits the drive of the motor (2) to the rotating shaft (6).

(9) is a transparent synthetic resin container which is mounted on the mounting portion (1b) of the base (1) and is detachably fixed by bayonet engagement. The rotating shaft (6) extends through the container (9) via the (10). (11) is a transparent synthetic resin lid that opens and closes the upper opening of the container (9) by bayonet engagement, and a handle (12) for removing the lid (11) is integrally formed on the top. Is forming.

(13) is a stirrer made of synthetic resin that is detachably mounted on the upper part of the rotating shaft (6) protruding into the container (9).
An engaging portion (14) that engages with the rotation stop (14), and this engaging portion (14)
A disk (15) that is formed integrally with the container (9) in close proximity to the inner bottom surface of the container (9), and has a ring shape integrally formed with the disk upward concentrically with the center of rotation of the disk (15). It is composed of a display tube (16). The display cylinder (16) is formed to have a smaller diameter than the outer diameter of the disc (15), and the outer periphery of the display cylinder (16) of the disc (15) serves as a foaming portion (15a) essential for foaming. It is formed to have a larger diameter than the outer diameter of the mating portion (14) and has a space from the outer diameter of the engaging portion (14). Furthermore, the indicator tube (16) is made up of a predetermined amount of ingredients, such as fresh cream, milk, egg yolk and sugar, placed in the container (9) for 6 to 7 minutes (1.6 to 2.0 times the initial volume). It is formed at a height at which a part of the material flows over the display tube (16) and flows into the above-mentioned interval when it foams. The display cylinder (16) is formed with a proper number of through holes (17) from the upper part to the disk (15) leaving the upper end, and the upper edge of the through hole (17) is inside the container (9). It is formed so that the liquid surface of a predetermined amount of the material put in the container reaches, and the upper edge of the through hole (17) is used as a guide when the material is inserted.

Next, the operation will be described. The container (9) is placed and engaged on the base (1), and the stirring body (13) is attached to the rotating shaft (6) protruding into the container (9) through the sleeve (10). Put a predetermined amount of ingredients such as fresh cream, milk, egg yolk and sugar into the container (9) up to the upper edge of the through hole (17) of the display cylinder (16) of the stirring body (13) (see FIG. 1A). ), The upper opening of the container (9) is covered with the lid body (11), and the motor (2) is driven to rotate the stirring body (13). Then, the foaming portion (15a) on the outer periphery of the display cylinder (16) of the disc (15)
The rotation of the material causes convection of the material, and air is continuously supplied into the material to foam. The material that has entered the gap between the engaging portion (14) of the stirring body (13) and the display cylinder (16) has a through hole due to centrifugal force.
Since it flows out from (17), no material that does not foam remains between the engaging portion (14) of the stirring body (13) and the display cylinder (16).

Since the viscosity of the material is low at the initial stage of operation, the material is agitated by the rotational force of the foaming portion (15a) of the disc (15) and convection occurs along the inner surface of the container (9) as shown in FIG. 1B. To do.

As the whipping progresses, the viscosity of the material increases, and the convection of the material due to the rotation of the whipping portion (15a) of the disc (15) is suppressed,
The indicator tube (16) gradually begins to be covered with material. At this time, the material is blown outward by the rotational force of the display cylinder (16) and repeats the operation of contacting the display cylinder (16) again (hereinafter referred to as pulsation). In this state, the material can take in air not only from the space between the outer periphery of the display cylinder (16) and the material but also from the through hole (17), and the foaming efficiency is higher than that without the through hole (17). Can be improved.

As the bubbling progresses further, the viscosity of the material increases, the pulsation becomes smaller, and the convection of the material due to the rotational force of the bubbling portion (15a) of the disc (15) significantly decreases, and a part of the material is displayed on the display cylinder.
It goes over (16) and flows into the space between the engaging portion (14) and the display cylinder (16) (see FIG. 1c). In this state, the lid (1
You can check through 1). This is the so-called "6-7 minute stand"
In this state, the material is optimally used as an ice cream dough that is foamed to 1.6 times to 2.0 times the initial volume.
At this time, the material covering the upper surface of the display cylinder (16) tends to be blown off by the rotational force, but a part of the material easily gets over the display cylinder (16) due to pulsation and the engaging portion (14) And the display tube (16). The stirring body (13) is preferably formed in a color different from that of the material so that it can be more clearly confirmed that the material has flowed into the gap between the engaging portion (14) and the display cylinder (16).

(G) Effect of the Invention According to the present invention, it is possible to provide a cooker that is extremely easy to handle, such as being able to easily and reliably determine the foaming state of materials without stopping operation. it can.
