Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a temperature detecting tool for cooking utensils.

[0002]

2. Description of the Related Art FIG. 1 shows a prior application (Japanese Patent Application No.
Fig. 3 is an embodiment diagram of a temperature detecting tool for a cooker of No. 3-313479), and Fig. 3 is an explanatory view showing only a part of a thermistor g taken out from Fig. 1. In the figure, a is a metal cylinder, b is its cap body,
c is a fixing bracket whose upper end is mounted in the metal cylinder a,
The lower end of the fixing member c is fixed to the fixing member d, and the upper end of the fixing member c is vertically slidably fitted into the metal cylinder a. A coil spring e is interposed between the upper surface of the fixing bracket c and the lower surface of the hat body portion b, and the hat body portion b is constantly moved upward by the elastic force of the coil spring e to abut the lower surface of the cooking device f. Reference numeral g denotes a thermistor attached to the lower surface side of the cap body portion b, and its withdrawal cord h is once withdrawn laterally and then bent downward to be connected to the connector i through the fixing metal fitting c. . Since the thermistor g is mounted sideways, the withdrawal cord h is withdrawn laterally, but it has already been proposed to fix the thermistor g vertically. In this case, the withdrawal cord h Is drawn vertically out of the thermistor g. FIG. 2 shows an example in which the thermistor g is mounted vertically, and it is mounted using a mounting base k for shaving, but since it is considerably troublesome, it seems that it has not been implemented just by a plan. .

[0003]

A method of vertically mounting the thermistor g as described above (FIG. 2) has also been publicly known, but vertically mounting is difficult because the fixing method is difficult. Absent. The thermistor g can be mounted sideways because it can be mounted by providing a simple mounting bracket made of a thin metal plate such as the mounting bracket j in FIG.

In the case of sideways mounting, the pull-out cord h is first pulled out to the side and then bent downward so that the vertical portion of the fixing bracket c can pass loosely. In the case of this structure,
When the cookware f is moved up and down violently like cooking of Chinese food, a problem of disconnection occurs. That is, when the cap body b and the thermistor g move up and down violently against the elastic force of the coil spring e, if the movement is too violent, the vertical portion of the withdrawal cord h in the fixing bracket c passes loosely. Even the cap body part b
Of the lead-out cord h in the metal tubular body a, it vibrates laterally like a temporary line. Although FIG. 3 is written over the actual movement for easy understanding, when the thermistor g is suddenly lowered together with the cap body b, the withdrawal cord h in the metal cylinder a is moved sideways. It will inflate elastically.

At this time, a bending phenomenon on the left and right sides as shown in FIG. 4 occurs at the portion indicated by the arrow a. When this is repeated, the wire is broken at the portion a. When an experiment is conducted using the experimental apparatus, an initial abnormality is seen in the portion indicated by the arrow A after the vertical movement of about 100,000 times. 10
The number of ten thousand times is almost safe in practical use, but it can be increased to about 300,000 times by one bending method of the withdrawal cord h at the portion a. FIG. 5 and subsequent figures are those of the present invention, which will be described in detail below.
