Description

[Detailed description of the invention] (a) Industrial application field This invention relates to an air conditioner in which a sensor for detecting indoor temperature and/or humidity is provided in a remote case separate from the body of the air conditioner.

(b) Conventional technology As shown in Japanese Patent Application Laid-open No. 11042/1983, sensors are built into the body of an air conditioner and a remote case that is remote from the body, and either one of these sensors is connected indoors. The temperature and/or humidity of the air conditioner is detected to control the operation of the air conditioner.

(c) Problems that the invention aims to solve If the remote case is installed in a place suitable for controlling indoor temperature and humidity, the temperature and humidity will be detected by the remote case's sensor; In locations where it is not appropriate to control temperature and humidity, a sensor inside the air conditioner detects the temperature and humidity and controls the operation of the air conditioner. Because the sensor remained protruding from the case, there was a problem where the remote case's sensor was mistakenly thought to be working.

The present invention provides an air conditioner that solves these problems.

(d) Measures to solve the problem This proposal provides a first sensor for detecting indoor temperature and/or humidity on the body of the air conditioner, and a remote case separate from the body that detects the indoor temperature and/or humidity. A second sensor for detecting humidity is provided, and the remote case has an opening, a holder for making the second sensor appear and disappear from the opening, and a signal from the second sensor when the second sensor is protruded. and a changeover switch for outputting the signal from the first sensor when the second sensor is immersed.

(e) Operation With the above-mentioned means, when the second sensor in the remote case is used, the holder is operated to project the second sensor from the case, so that the temperature and/or humidity in the room can be accurately detected. On the other hand, when the first sensor in the aircraft is used without using the second sensor in the remote case, the holder is operated to retract the second sensor into the case, so that there is no misunderstanding that the second sensor in the remote case is operating.

(f) Example To explain based on the drawings, in Fig. 8, 1
The body 6 includes a centrifugal blower 2, a heat exchanger 3, and an electrical box 4 and is installed in a ceiling space 5, and a decorative panel 10 has an inlet 7 and an outlet 8 and is attached to the lower surface of the ceiling 9. A first sensor 11 for detecting temperature and/or humidity is provided in the suction passage between the suction port 7 and the centrifugal blower 2.

Reference numeral 12 denotes a remote case that controls the operation of the air conditioner 1, and as shown in FIGS. 1 to 7, the lower case 13 of this case includes an operation switch 14, a heating/cooling switch 15, a temperature control switch 16, and a wind speed switch. A lid 18 that covers an operating section such as a switch 17, a test run switch, etc., a second sensor 19 that detects temperature and/or humidity, and a sensor holder 22 that makes this sensor appear and retract from an opening 21 of an upper case 20. is provided.

This sensor holder 22 is attached to the sensor 1
9, a guard part 23 that covers the sensor 19, and a blind part 24 that blocks the opening 21, and rotates together with the guard part and the blind part in the direction of the arrow shown in FIGS. 1 and 5. As shown in FIG. 4, a diagonal groove 26 is provided on the outer peripheral surface of this rod-shaped member 25, and the lever 2 of the changeover switch 27 of the sensors 11, 19 is inserted into this groove 26.
8 is fitted.

29 is a hole for screwing the remote case 12 to the connection box 31 embedded in the indoor wall 30;
2 is a transparent plate, 33 is a switch 14, 15, 16,
17 is a liquid crystal display unit, 34 is a printed circuit board, and remote case 12 and electrical box 4 are connected to a metal pipe 35.
They are connected by a lead wire 36 inserted inside.

Next, the operation of the present device will be explained. If the installation location of the remote case 12 is suitable for controlling indoor temperature and humidity, then from the state shown in FIG. 5, lift the guard part 23 upward by hand as shown by the solid arrow and set it to the state shown in FIG. 1. The rod-shaped portion 25 also rotates at the same time, and the lever 28 of the changeover switch 27, which is fitted into the groove 26 of this rod-shaped portion, moves to the right, and the first
The second sensor 11 is disconnected from the operation control circuit, and the second sensor 19 is connected to the operation control circuit.

Next, after connecting the lower case 13 with the lead wire 36 and screwing the hole 29, when the upper case 20 is fitted into the lower case 13, the guard part 23 and the second The sensor 19 protrudes from the opening 21 of the upper case 20. Therefore, the temperature and humidity of the indoor air convecting along the indoor wall 30 is
The air conditioner 1 is accurately detected by the sensor 19, and the air conditioner 1 is operated based on the signal from this sensor.

On the other hand, if the installation location of the remote case 12 is not suitable for controlling indoor temperature and humidity, the guard part 23 can be moved from the state shown in FIG. 1 to the state shown in FIG. When set, the rod-shaped portion 25 also rotates in the opposite direction at the same time, and the lever 28 of the changeover switch 27 fitted in the groove 26 of this rod-shaped portion moves to the left, and the second sensor 19
is disconnected from the operation control circuit, and the first sensor 11 is connected to the operation control circuit.

Next, when the upper case 20 is fitted into the lower case 13, the blind part 24 opens into the opening 2 as shown in FIGS. 6 and 7.
1 and the outer surface of the blind part 24 is the upper case 20.
The second sensor 19 is flush with the outer surface of the sensor 19.
is inserted into the remote case 12, so the second
There is no risk of misunderstanding that the sensor 19 is working, and the remote case 12 has a clean appearance that prevents dust from entering through the opening 21. In this case, the operation of the air conditioner 1 is controlled by a signal from the first sensor 11 that detects the temperature and humidity of the intake air.

Note that, unlike the above embodiment, the remote case 12
is a switch 14,1 for controlling the operation of the air conditioner 1.
The second sensor 1 without providing 5, 16, 17, etc.
9 may be provided, or the switch 27 of the first and second sensors 11, 19 and the sensor holder 22 may not be interlocked.

Furthermore, if the word "sensor" is printed or colored on the front surface 37 of the guard portion 23 of the sensor holder 22, the presence of the second sensor 19 becomes clear.

(g) Effect of the invention According to this proposal, when using the second sensor installed in the remote case, the second sensor installed in the remote case is
Since the sensor is protruded, indoor temperature and/or humidity can be accurately detected. On the other hand, when using the first sensor inside the aircraft without using this second sensor, this second sensor is inserted into the remote case, and the second sensor is
Since the operation of the second sensor is stopped and the first sensor is activated, it is possible to prevent the user from misunderstanding that the second sensor is working.
