Description

DETAILED DESCRIPTION OF THE INVENTION Industrial Field of the Invention The present invention relates to a mounting device of a mounting type integrated disc thermometer for detecting the temperature of a heating device.

2. Description of the Related Art Conventionally, a mounting device for a disc thermostat of this type has a structure as shown in FIGS. That is,
The disk thermo body 1 is held by the mounting portion 2, and the mounting portion 2 is integrally formed with the heat sensitive portion 2a and has two mounting holes (not shown). As shown in FIG. 3, the mounting of the disc thermostat is carried out by directly fixing the mounting portion 2 to the mounting member 3 with the screw 4, and the heat sensitive portion 2a is brought into contact with the heat sensitive portion 5, or As shown in the figure, one end of a mounting member 6 having a spring property is fixed to a mounting member 7 with a screw 8, and the other end of the mounting member 6 presses the mounting portion 2 of the disk thermo body 1 by its spring property. The heat-sensitive portion 2a is brought into contact with the heat-sensitive portion 9.

However, with such a structure, the heat-sensitive part 5,
In the case of 9 which is attached and detached like a pot of a rice cooker, in the case of FIG. 3, the disc thermo body 1 is fixed to the mounting member 3 and the position of the heat-sensitive part 5 formed of the pot is fixed. Since the heat-sensitive part 2a and the heat-sensitive part 5 are not securely contacted with each other, and in the case of FIG. 4, since the mounting bracket 6 holds only half of the mounting part 2 from one side, the heat-sensitive part like a pot There is a problem in that the heat-sensitive portion 2a wobbles when the portion 9 is attached or detached, or the surface of the heat-sensitive portion 2a inclines with respect to the heat-sensitive portion 9, resulting in unstable contact.

The present invention solves such a problem, and ensures that the heat-sensitive part and the heat-sensitive part are in contact with each other even when the position of the heat-sensitive part varies a little or the heat-sensitive part is detached. That is the purpose.

Means for Solving the Problems In order to achieve the above object, the present invention provides a hole in which a heat-sensitive portion of a disk thermostat projects in the center of a member having a spring property, and slit-shaped elongated holes parallel to both sides of the hole. Is provided, and the mounting portion of the disc thermostat is sandwiched between the inside and the outside of the two slit-shaped long holes, and a part of the member having the spring property is used as another member located near the heat-sensitive portion of the disc thermostat. It is designed to be fixed.

Action According to the above configuration, since the member having the spring property sandwiches both sides of the mounting portion of the disk thermo from both sides, the heat-sensitive portion integrally formed in the mounting portion does not wobble,
Further, since the member having the spring property has the spring property independently on both sides of the two slit-shaped long holes, the heat-sensitive part can be moved according to the contact condition of the heat-sensitive part,
Therefore, if the variation in the position of the heat-sensitive portion is equal to or less than the movable amount of the heat-sensitive portion, the heat-sensitive portion and the heat-sensitive portion can reliably contact each other without tilting the contact surface.

Embodiment An embodiment of the present invention will be described below with reference to the accompanying drawings. In FIG. 1 and FIG. 2, 11 is a pot of a rice cooker, and the pot 11 is detachably accommodated in a protective frame 12.
The temperature of the side surface of the pot 11 is detected by a disc thermostat 13 integrated with a mounting part. There are two holes 14b for use. Reference numeral 15 is a mounting metal fitting having a spring property, and this mounting metal fitting 15 has a round hole 15a at the center of which the heat-sensitive portion 14a of the disk thermostat 13 projects,
And on both sides of this round hole 15a are slit-shaped elongated holes 15b parallel to each other.
Is provided. The distance between the two elongated holes 15b is larger than the dimension A on the narrow side of the mounting portion 14 and smaller than the dimension B on the wide side. The length of the elongated hole 15b extends to a position outside the outer diameter line a when the heat-sensitive portion 14a is projected from the round hole 15a of the mounting member 15 and the mounting portion 14 is rotated. Further, the protective frame 12 is also provided with a round hole 12a through which the heat-sensitive portion 14a of the disc thermostat 13 protrudes, and further, the mounting bracket 15 has the heat-sensitive portion 14a.
The rivet 16 is fixed to the protective frame 12 in a state of protruding from the second round hole 12a toward the pot 11 side.

Next, when the disc thermo 13 is attached to the attachment fitting 15, its attachment and operation will be described. First, from the state in which the heat-sensitive portion 14a of the disc thermo 13 is projected from the round hole 15a of the mounting bracket 15 and the mounting portion 14 of the disc thermo 13 is located between the two elongated holes 15b provided in the mounting bracket 15, Slot 1
Insert the wide side of the mounting portion 14 under both outer sides of 5b, and rotate it to a position at right angles to the slot 15b. As a result, the mounting portion 14 is sandwiched between the inside and the outside of the two elongated holes 15b provided in the mounting bracket 15. Further, the mounting member 15 is provided with a cut-and-raised portion 15c which is inserted into the mounting hole 14b so that the mounting portion 14 is fixed at that position.

Regarding the operation of the disc thermostat 13, the heat sensitive portion 14a is movable by bending the portions on both sides of the elongated hole 15b of the mounting bracket 15 having spring property, and the pan 11 is protected by the protective frame 1.
When accommodated in 2, the accommodation position will vary by the difference between the outer diameter of the pot 11 and the inner diameter of the protective frame 12, but in this case, since the heat-sensitive portion 14a surely contacts the pot 11, the pot When the 11 is not housed in the protective frame 12, the protective frame 12 of the heat-sensitive part 14a
The margin from the inner surface of the pot is larger than the variation in the position of the pot 11. Further, the movable amount of the heat sensitive portion 14a is larger than the variation amount of the position of the pan 11. Therefore,
When the pan 11 is housed in the protective frame 12, first, one end of the heat-sensitive part 14a is pushed, and the corresponding part of the mounting bracket 15 bends accordingly, so that the surface of the heat-sensitive part 14a hits the pan 11 vertically. Become.

Effects of the Invention According to the present invention, as is clear from the description of the above embodiment,
Since both sides of the mounting portion of the disc thermostat are sandwiched between the inside and the outside of the two slit-shaped elongated holes provided in the member having the spring property, the heat-sensitive portion of the disc thermostat does not wobble. Further, since the member having the spring property has the spring property independently on both sides of the two slit-shaped elongated holes,
The heat-sensitive part can be moved according to the contact condition of the heat-sensitive part.As a result, if the variation in the position of the heat-sensitive part is less than the movable amount of the heat-sensitive part, the contact surface between the heat-sensitive part and the heat-sensitive part is It surely contacts without tilting.
