Abstract

A temperature detection module for detecting a temperature of a measurement target is provided. The temperature detection module includes a temperature sensor, and a holder for holding the temperature sensor such that movement is possible in a separation and contact direction in which the temperature sensor is separated from and brought into contact with the measurement target. The temperature sensor includes a sensor main body portion in which a temperature detection element is accommodated, and a spring portion that is integrally provided on the sensor main body portion. The spring portion is of a type that expands and contracts only in a single direction, and expands and contracts only in the separation and contact direction. The spring portion is attached to the holder and biases the temperature sensor such that a detection surface comes into contact with the measurement target.

First claim

The invention claimed is:

1. A temperature detection module for detecting a temperature of a measurement target, comprising:
a temperature sensor; and
a holder configured to hold the temperature sensor such that movement is possible in a separation and contact direction in which the temperature sensor is separated from and brought into contact with the measurement target,
wherein the temperature sensor includes:
a sensor main body portion in which a temperature detection element is accommodated; and
at least two spring portions provided integrally on the sensor main body portion and having end portions on a side opposite to the sensor main body portion in the separation and contact direction that are coupled together,

the spring portions expand and contract only in a single direction, and expand and contract only in the separation and contact direction, and
the spring portions are attached to the holder and bias the temperature sensor such that a detection surface comes into contact with the measurement target.

2. The temperature detection module according to claim 1 ,
wherein stoppers configured to come into contact with each other and thus restrict the position of the temperature sensor relative to the holder when the temperature sensor is displaced to a restriction position are provided between the holder and the temperature sensor.

3. The temperature detection module according to claim 1 ,
wherein the holder includes a locking portion that is locked to the spring portions in a direction orthogonal to the direction in which the spring portions expand and contract.

4. The temperature detection module according to claim 3 , wherein the spring portions are arranged at positions that are rotationally symmetrical with respect to a center of the sensor main body portion.
