Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to an improvement of a creamer container for an ice creamer incorporated in a freezer compartment of a refrigerator body.

[Conventional technology]

FIG. 8 shows, for example, Japanese Patent Application No. 1-37590 filed by the applicant earlier.
FIG. 1 is a cross-sectional view showing an ice creamer incorporated in a freezer compartment of a conventional refrigerator-freezer shown in FIG.
Is a freezer compartment, and (2) is a creamer main body fixed to a partition shelf (3) partitioning the freezer compartment with screws or locking claws.

The creamer body is provided with a creamer motor (4), a plurality of gears (5) for decelerating and transmitting the rotation of the motor, and a rotation transmission shaft (6) which is directly connected to the gear of the final group and rotates. . The creamer container (7) shown enlarged in FIG. 9 is made of aluminum or the like which is a highly heat-conductive member, and has a protrusion (7a) at the center of its lower surface.
(8) has a stirring fan having a plurality of stirring blades (8a), the lower end of which is fitted to the projecting portion (7a) for axial support and the uppermost end of which is fitted with the rotation transmission shaft (6). Recess (6a)
The convex portion (8b) that fits with is integrally formed. (9)
Is a lid for detachably covering the upper opening of the creamer container (7), and the convex portion (8) of the stirring fan (8) is provided at the center thereof.
A shaft hole (9a) through which b) passes is drilled.

Reference numeral (8C) is a positioning flange integrally formed with the stirring fan (8), and is axially supported by the shaft hole (9a) and acts as vertical positioning so that the stirring fan can smoothly rotate.

Reference numeral (10) is an aluminum tray containing a lid cooling material installed on the floor surface (1a) of the freezing room, on which the creamer container (7) is placed.

(11) is a band made of synthetic resin for preventing frostbite when a wet hand or the like is in direct contact with the creamer container (7) made of aluminum or the like which is a heat conductive member when it is cooled. The frame is attached to the outer peripheral surface of the creamer container (7). The frame is composed of a lid mounting flange (11a), a tapered caulking flange (11b), and a frostbite protection wall (11C).

The upper end of the creamer container (7) is folded back outward in a U-shaped cross section, and the outer peripheral portion (7b) is caulked so as to be in close contact with the tapered surface of the tapered caulking flange (11b) of the frame (11).

In this state, as shown in Fig. 10, the inner peripheral surface of the frame (11
d) and the outer surface (7C) of the creamer container have a gap (13) of a predetermined size. When the container outer wall (7C) and the frame inner surface (11d) vary in size and the container is washed with hot water, etc. It is configured to prevent cracking and deformation of the frame (11) due to thermal expansion or contraction of the synthetic resin due to high temperature or low temperature during ice cream production.

Next, the operation will be described. Put the ice cream raw material in the creamer container (7), set the stirring fan (8) and the lid (9), and then set the aluminum tray (1) containing the cold storage material in the freezer compartment (1).
0) Set it to the specified position above. Next, the fitting concave portion (6a) of the rotation transmission shaft (6) of the creamer main body is fitted into the convex portion (8b) at the uppermost end of the stirring fan (8), and the creamer motor (4) is driven. By turning on the start switch (not shown), the creamer motor (4) is rotationally driven, and is sequentially written to the stirring fan (8) via the plurality of gears (5) and the rotation transmission shaft (6). The stirring force (8a) of the stirring fan is rotated by the deceleration transmission of the rotational force, and while the air is mixed with the ice cream raw material, it is made into a cream and is cooled by the cooler (not shown). Due to the cold storage effect of the aluminum tray (10) containing the cold storage material, the creamer container (7) is rapidly cooled from around and on the floor side, and ice cream is completed in a short time.

[Problems to be solved by the invention] Since the conventional ice creamer container is configured as described above, since the outer periphery of the creamer container is in close contact with only the tapered surface of the tapered caulking flange of the frame, Due to the deformation of the frame during caulking work and repeated high and low temperatures of the container, heat shrinkage of the synthetic resin frame may cause the inner peripheral surface of the frame and the outer peripheral surface of the creamer container to come into close contact, as shown in Fig. 11. There is a deviation from the crimped state,
The frame does not adhere to the creamer container and it moves up and down,
There was a problem that it had to be repaired by rotating it, which resulted in defective crimping.

The present invention has been made to solve the above problems, and an ice cream that can prevent the crimping of the frame and the creamer container from being defective and can absorb the variation in the dimensions of the outer peripheral portion of the creamer container and the inner peripheral surface of the frame. The purpose is to obtain a creamer container.

[Means for Solving the Problems]

In the ice creamer container according to the present invention, a plurality of thick parts for adhesion are formed on the inner wall of the frame, and only the thick parts of the frame on the outer peripheral surface of the creamer container are adhered to each other. A gap having a predetermined size is formed between the outer peripheral surfaces of the container.

[Action]

When the outer peripheral portion of the ice creamer container in this invention was caulked so as to be in close contact with the tapered surface through the tapered caulking flange of the frame, the thick wall portion for adhesion formed on the inner peripheral surface of the frame was caulked to the outer peripheral surface of the creamer container. Due to the pressurization at this time, the frame and the creamer container are firmly fixed by the close engagement.

[Example of device]

An embodiment of the present invention will be described below with reference to the drawings. Note that the same or corresponding portions as those of the conventional one are designated by the same reference numerals and the description thereof is omitted. In FIGS. 1 to 3, (14) is the inner peripheral surface (11d) of the frame of the tapered caulking flange (11b).
Is a plurality of thick parts for adhesion which are integrally formed with each other. 4 and 5 show another embodiment of the present invention,
A notch (15) is provided on the outside corresponding to the thick part (14) for adhesion, and is formed by punching on the outer peripheral part (7b) of the creamer container (7) corresponding to this notch. The circular boss (16) is locked so as to come into close contact with the notch (15).

Therefore, at the joint between the creamer container (7) and the frame (11) by caulking, there is a gap of a predetermined size between the outer peripheral surface (7C) of the creamer container (7) and the inner peripheral surface (11d) of the frame. In order to provide (13), the frame (11) is deformed during caulking work, repeated high and low temperatures of the creamer container (7), or dimensional variation of the outer wall (7C) of the creamer container (7), etc. ) Is firmly fixed to the caulked part with no gaps by the thick-walled part (14) for adhesion, which is arranged in an appropriate size so that cracking does not occur. Also, if the circular boss (16) is formed on the outer peripheral portion (7b) as in the other embodiment of the present invention, the frame (11) and the creamer container (7) are coupled more firmly without rotating.

In the above embodiment, the inner peripheral surface (11d) of the frame (11)
A crack (13) with a predetermined size was formed between the creamer container (7) and the outer peripheral surface (7C) to prevent cracking of the frame (11). During cleaning, ice cream raw material and dirty water may infiltrate and adhere to the gap (13), and even after the creamer container (7) is dried, it is difficult to remove dirt and mold, and so on. As shown in Figure 7, the tip edge of the frostbite protection wall (11C) of the frame (11) is
A close flange (17) may be provided so as to be in close contact with C). Since this close flange (17) is formed in a fin shape, even if the dimensions of the outer peripheral surface (7C) of the creamer container (7) vary slightly, only the tip is in contact and the frostbite protection wall (11
Since part C) is elastically deformed, there is no risk of cracking due to dimensional variations of the creamer container (7), thermal shrinkage at high or low temperatures, or cracking due to thermal expansion.

[Effect of device]

As described above, according to the present invention, since the plurality of thick-walled portions for adhesion are provided on the inner wall of the frame and the outer wall of the creamer container is closely joined to the inner wall of the frame by caulking, the creamer is formed only by the thick-walled portion of the frame. It has a practical effect such that it is closely attached to the container side and a gap of a predetermined size is formed in the other part, and there is no risk of caulking failure due to thermal contraction of the synthetic resin due to variations in the caulking part or repeated high and low temperatures.
