温の変化に対しての応答速度が遅いという問題もある。Conventionally, various types of temperature sensors for bathtubs have been provided as shown below. The one shown in Fig. 81 is a temperature sensor (2) in the form of a cell placed in hot water and suspended from the lid (9) of the bathtub (1). It is inserted when detecting the water and taken out when taking a bath so as not to get in the way.
Taking it in and out is a hassle. As shown in Fig. 2 and Fig. 3, there is a system that fixes the temperature in the bathtub 11) to solve this trouble of putting in and taking out the bathtub. Since it is attached in a shape that protrudes inside the bathtub +11, it can accurately detect the hot water inside the bathtub +11, but on the other hand, it gets in the way when bathing. The heat-sensitive element (6) is arranged near the inner peripheral surface of the bathtub (1) so as not to protrude into the bathtub (1). a) Since a temperature gradient toward the middle X direction occurs around the heat-sensitive element (5) within the sensor holder (4), it is difficult to accurately measure the water temperature, and If the heat-sensitive element 11 is disposed misaligned in the Since the contact area with hot water is small, there is also the problem that the response speed to changes in hot water temperature is slow due to the heat capacity of N.

ｅＭ性の充填材（１１）で満たされる。Embodiments of the present invention will be described below based on the drawings. Basically, the bathtub temperature sensor according to the present invention is attached to the inner circumferential wall of the bathtub f11, opens inward of the bathtub ill, and is recessed from the inner circumferential wall of the bathtub (1), as shown in Figures 7iA5 and M6. A mounting body 13) provided with a recess (2) and a recess (
2) It is installed protruding inside and its outer circumferential surface covers almost the entire surface of the bathtub +1
The device is characterized by being composed of a hollow t-cosa holer (14) that is immersed in the water inside the sensor hole (14), and a heat-sensitive element (6) that is housed in the sensor hole (4) and detects the temperature of the outer circumferential surface of the sensor hole (4). . The mounting body 13) has a paper-like shape with a flange extending from the opening edge, and
A cylindrical sensor holter (4) is integrally formed to protrude from the center of the drawing. The tip of the cover R1 (4) is closed, and the base opens outward from the bottom surface of the mounting body (31. The tip of the sensor holder 14) faces approximately on the same plane as the opening surface of the mounting body +31.・However, the sensor holder (4
) has a shape protruding into the recess f21 of the mounting body (3). A heat-sensitive element such as a thermistor: 6) is housed inside the sensor holter (4), and the sensor holter (4)
4) A gap between the inner peripheral wall and the heat-sensitive element (6) is filled with an eM filler (11) having good thermal conductivity.

ものである。The temperature control chamber formed as described above is placed in a bathtub il+, as shown in FIG. That is, a mounting hole 11 is formed in one place on the peripheral wall of the bathtub 11), and the mounting body (3) is inserted from the inside of the bathtub (1) into the flange (10). is secured to the inner circumferential wall of the bathtub 1.11. A thread is cut on the circumferential surface of the part of the mounting body (3) that protrudes to the outside of the bathtub (1). (15) is interposed. The hot water in the bathtub 11) enters the inside of the mounting body (3) of the temperature sensor (A) attached to the bath 14711+ in this way, that is, the recess (2), and as a result, the sensor holster (4)
) will be almost completely submerged in hot water. Therefore, almost no temperature gradient occurs in the sensor holder (4), and the silkworm body surrounding the heat-sensitive element (6) has a substantially uniform temperature rC. Thereby, even if the position of the heat-sensitive element (6) is slightly shifted in the X direction in FIG. 6, the temperature can be detected without any influence.

つきが少なくなって歩留りがよいという利点を有する。As described above, the present invention has a sensor holster that holds a heat-sensitive element protrudingly provided in a recess that is recessed below the inner circumferential wall of the bathtub provided in the mounting tube. It has the advantage that it does not get in the way when taking a bath while the temperature sensor remains fixed, and the sensor holter is protruded into the recess so that its outer circumferential surface is submerged in hot water over almost the entire surface. As a result, the temperature around the heat-sensitive element becomes approximately equal, and as a result, it is possible to accurately detect one time, and even if the position of the heat-sensitive element is slightly shifted, there is almost no effect on the characteristics of the temperature sensor. This has the advantage of reducing product variation and improving yield.
