[0016] [First embodiment] FIG. 1 is a plan view showing a controller according to a first embodiment of the present invention. This controller 1 is a wired or wireless controller that controls the operation of the heating and cooling equipment, and is formed in a substantially rectangular shape. The controller 1 is provided with a display unit 1A on the front side for displaying menus and the like, and further provided with a plurality of air holes (ventilation holes) 1B for detecting room temperature in the left corner. Although detailed illustration is omitted here, the information displayed on the display unit 1A can be seen through a see-through part arranged to cover the opening of the upper case 2.

[0017] Fig. 2 is a cross-sectional view of the controller taken along line AA in Fig. 1. The controller 1 includes an upper case 2 having an air hole 1B, a lower case 3 which is combined with the upper case 2 to form the case of the controller 1 together with the upper case 2, a temperature sensor 4 as a temperature detection means, a temperature sensor holding part 5 which holds the temperature sensor 4, a wiring board 6, and a cushioning material 7. The upper case 2 and the lower case 3 are formed by injection molding of resin, and are integrated together by hooks and / or screws. The temperature sensor 4 is composed of a sensor body 4A as a temperature detection section, and a lead wire 4B connected to the sensor body 4A. Although various configurations capable of detecting temperature can be applied to the temperature sensor 4, a thermistor is applied in this embodiment. The temperature sensor holding component 5 includes a first temperature sensor holding component 11 and a second temperature sensor holding component 12.

[0018] Fig. 3 is a perspective view showing the first temperature sensor holding part 11, and Fig. 4 is a perspective view showing the second temperature sensor holding part 12. Fig. 5 is a perspective view showing the first temperature sensor holding part 11 from the opposite side to Fig. 3, and Fig. 6 is a perspective view showing the second temperature sensor holding part 12 from the opposite side to Fig. 4. The first temperature sensor holding component 11 and the second temperature sensor holding component 12 are formed by injection molding of resin. The first temperature sensor holding part 11 has a cylindrical body and an opening 21 formed in a position corresponding to the air hole 1B. The temperature sensor holding part 5 holds the sensor body 4A of the temperature sensor 4 in this opening 21. As a result, the controller 1 holds the sensor body 4A near the air hole 1B without blocking the air hole 1B, and is configured to be able to detect room temperature with sufficiently high accuracy with a simple configuration that only requires forming the air hole 1B on the upper case 2 side.

[0019] Furthermore, the first temperature sensor holding component 11 includes a tongue-shaped (inclined wall-shaped) mating portion (guide portion) 22 for mating the lead wire 4B of the temperature sensor 4, and a first guiding portion 23 formed of a recessed groove for guiding the lead wire 4B of the temperature sensor 4 to the mating portion 22. The mating portion 22 functions as a portion capable of guiding (a required portion of) the lead wire 4B. In this embodiment, the recessed groove associated with the first guiding portion 23 is configured in a substantially V-groove shape. Thereby, the controller 1 holds the lead wire 4B of the temperature sensor 4 in a predetermined position, thereby holding the sensor main body 4A in a predetermined position, and the sensor main body 4A can be easily disposed in the predetermined position and assembled.

[0020] The second temperature sensor holding part 12 is formed in a substantially cylindrical shape and has a space S provided at a position corresponding to the air hole 1B and the opening 21. The second temperature sensor holding part 12 is inserted into the first temperature sensor holding part 11 and held by the first temperature sensor holding part 11. For this reason, the second temperature sensor holding part 12 is provided with a locking piece 33, and the first temperature sensor holding part 11 is provided with a groove 24 into which the locking piece 33 locks. Thus, the temperature sensor holding part 5 is configured to be easily assembled. Furthermore, the second temperature sensor holding part 12 has a second guiding part 31 formed of a recessed groove that guides the lead wire 4B of the temperature sensor 4 to the fitting part 22 of the first temperature sensor holding part 11, and a pressing part 32 that presses the lead wire 4B of the temperature sensor 4 against the upper case 2. The second guiding part 31 and the pressing part 32 are arranged side by side in the space between the fitting part 22 and the first guiding part 23. The recessed groove associated with the second guiding part 31 is configured in a substantially V-groove shape. By providing the second guiding part 31 and the pressing part 32 in this manner, the controller 1 can hold the sensor main body 4A in a predetermined position more reliably.

[0021] 7, the upper case 2 is formed with a cylindrical positioning wall 41 surrounding the air hole 1B, and is further formed with a positioning recess 42. The first temperature sensor holding component 11 is provided with a positioning rib 26 that abuts against the positioning wall 41, and a positioning protrusion 25 that corresponds to the positioning recess 42 (FIG. 3). As a result, the rib 26 and the protrusion 25 form a positioning portion for positioning the temperature sensor holding component 5 in the upper case 2, and the controller 1 can be assembled even more easily.

[0022] The wiring board 6 (FIG. 2) is connected to the lead wire 4B of the temperature sensor 4, and is equipped with a signal processing circuit for detecting the room temperature by the temperature sensor 4, a drive circuit for driving the display unit 1A, and the like. The lead wire 4B of the temperature sensor 4 is conductively connected to one surface 6A of the wiring board 6 facing the lower case 3. The lead wire 4B is routed and arranged in the order of the fitting portion 22, the second guide portion 31, the holding portion 32, and the first guide portion 23 from the connection point with the wiring board 6 toward the sensor main body 4A. At this time, due to the fact that the fitting portion 22 is inclined from the lower case 3 side toward the upper case 2 side as it moves away from the connection point with the wiring board 6, the lead wire 4B is guided to approach the upper case 2 side, and is hooked and fixed by the second guide portion 31 when passing through the gap between the fitting portion 22 and the second guide portion 31. In this case, the lead wire 4B portion located between the gap and the sensor main body 4A is hooked and fixed in a serpentine manner by utilizing the holding portion 32 provided on the second temperature sensor holding component 12 and the first guiding portion 23 provided on the first temperature sensor holding component 11. Here, since the tip portion of the holding portion 32 that guides the lead wire 4B and the tip portion of the first guiding portion 23 that also guides the lead wire 4B are located near the upper case 2, the sensor main body 4A is disposed adjacent to the air hole 1B of the upper case 2 at the opening 21, and the accuracy of detecting the room temperature can be improved.

[0023] The cushioning material 7 may be a flexible material, and is provided between the second temperature sensor holding component 12 and the lower case 3 for the purpose of absorbing dimensional variations of each component by elasticity. By absorbing dimensional variations of each component by elasticity in this way, the assembly can be simplified by a further simple configuration. Various configurations may be used for the cushioning material 7, and for example, double-sided tape or adhesive may be used. The cushioning material 7 may be provided on the upper case 2 side.

[0024] According to the above configuration, the temperature sensor can be arranged without providing a mechanism for holding the temperature sensor in the upper and lower cases by holding the sensor main body 4A near the air hole 1B using the temperature sensor holding part 5 having the opening 21 formed in the part facing the air hole 1B, and this allows the upper and lower cases to be flexibly used for other products. Furthermore, by providing the fitting part 22 (more specifically, the fitting part 22 and the first guide part 23), assembly can be simplified.

[0025] Furthermore, the second temperature sensor holding part 12 is formed in a cylindrical shape and is inserted into the first temperature sensor holding part 11 so as to be held by the first temperature sensor holding part 11, which makes assembly even easier. Furthermore, by providing the second guiding part 31 and the pressing part 32, the sensor main body 4A can be held in a predetermined position even more reliably.

[0026] Furthermore, by providing the positioning portion, the temperature sensor holding component 5 can be easily positioned in the upper case 2.

[0027] Furthermore, the elasticity of the cushioning material 7 absorbs the dimensional variations of the various parts, and the assembly can be simplified by the simple structure.

[0028] Other Embodiments Although specific configurations suitable for carrying out the present invention have been described in detail above, the configurations of the above-described embodiments can be modified in various ways without departing from the spirit of the present invention.
