DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a kettle with a whistle for notifying that hot water is boiling by means of a whistle attached to an opening of a spout, and in particular, a lid-shaped whistle unit provided with a whistle is attached to the kettle body. The present invention relates to a mounting structure of a whistle unit used for a vehicle.

[0002]

2. Description of the Related Art Conventionally, a kettle with a whistle as described above is formed in a lid shape so that when boiling hot water, water vapor at the time of boiling passes through the whistle portion of the whistle unit to generate an alarm sound. While the whistle unit is installed at the position that closes the spout of the kettle, the spout must be opened when pouring boiling water into a pot or teapot. And is pivoted between a position where the spout is closed and a position where the spout is opened.

As a mounting structure of a whistle unit in such a kettle with a whistle, for example, Japanese Utility Model Laid-Open No.
No. 735, Japanese Utility Model Laid-Open No. 2-8330, Japanese Utility Model Application Sho 61
These are disclosed in, for example, Japanese Patent Application Laid-Open Nos. 1806285, 2-63731 and 6-66526.

[0004]

However, in the mounting structure of the whistle unit described in the above-mentioned Japanese Utility Model Application Laid-Open Publication No. Sho 62-123735, the tip of the shaft rod inserted through the bearing fitting is swaged. In addition, the workability of mounting the whistle unit is poor, so that not only a lot of manpower and time are required for mounting, but also the swaged portion is exposed, so that the appearance design is inferior and the whistle unit cannot be replaced in case of failure.

In the structure disclosed in Japanese Utility Model Laid-Open Publication No. 2-8330, the whistle unit is mounted by screwing, and is concealed by the tip of the handle so that the head of the screw is not visible. The whistle unit is not always easy to replace because it takes a lot of time and effort to attach it, and it is necessary to remove the handle when removing it.

The mounting structure described in Japanese Utility Model Laid-Open Publication No. 61-180285 discloses a shaft that covers both sides of a bearing with a concave portion provided at the tip of a handle without caulking a shaft that supports the whistle unit. Although it is intended to prevent the rod from falling off, it is necessary to remove the handle, so that there is a problem in the workability of replacing the whistle unit as in the structure described in Japanese Utility Model Application Laid-Open No. 2-8330.

In Japanese Utility Model Laid-Open No. 2-63731,
A structure is disclosed in which a cover body is put on the outside of the bearing fitting to prevent the bearing rod from dropping off from the bearing fitting without caulking the bearing rod that supports the whistle unit. Although the mounting workability and replacement workability are relatively good, since separate members are used,
The number of parts and the number of assembling steps increase, and cost increases are inevitable.

In Japanese Utility Model Laid-Open Publication No. Hei 6-66526, a bearing fitting is covered with an end piece provided in a whistle unit.
Although a structure for preventing the shaft from dropping from the bearing is described, the end piece of the whistle unit becomes an obstacle when the shaft is inserted into the through hole of the bearing and the through hole of the whistle unit. There is a problem that installation and replacement of the whistle unit are troublesome, and solving these problems has been a problem in the production or quality of a kettle with a whistle.

In order to prevent the shaft of the whistle unit from being exposed, as shown in FIG. 10, recesses 101, 101 are formed without passing through the shaft hole in the bearing fitting 100, and the recesses 101, 101 are formed by the recesses 101, 101. A structure for supporting both ends of the shaft rod 102 is conceivable. In this case, the bearing 100
In order to not only increase the manufacturing cost, but also to prevent the shaft 102 from dropping due to deformation of the bearing fitting 100, for example,
Japanese Utility Model Application Laid-Open No. 2-8330 or Japanese Utility Model Application Laid-Open No. 61-1.
As described in Japanese Patent Application Laid-Open No. 806285, it is necessary to take measures to prevent deformation of the bearing bracket, such as sandwiching the bearing bracket by the end of the handle, which causes an increase in cost and also causes attachment and detachment of the whistle unit. On the contrary, it takes time and effort.
