Description

[Detailed Description of the Invention] This invention relates to a remote control device for electrical equipment having a timer operation function.

Microcomputers and electronic controllers used to control electrical equipment generally have a timer operation function, and a timer time reduction circuit for operation tests is usually added to this timer operation function. . This timer time reduction circuit is a so-called short circuit, and by short-circuiting it during manufacturing tests or maintenance services, it shortens the timer operation time from, for example, 3 hours to 3 minutes, and thereby tests the timer operation function. This makes it possible to do this in a short time.

By the way, as mentioned above, the timer operation function is tested only a few times, such as during manufacturing tests or during maintenance services, and a special short-circuit switch is installed just to short-circuit the timer time reduction circuit. I didn't do that. However,
When actually conducting the test, the tester connected two lead wires on the circuit board of the timer time reduction circuit, and used these lead wires to perform short-circuit measures. After the test was completed, the lead wires were removed. however,
Such short circuit treatment is a very troublesome task for the test personnel, and causes a significant drop in work efficiency, especially when testing a large number of devices.

This idea was made in view of the above circumstances, and its purpose is to easily test the timer operation function without the need to install a special switch or to perform any troublesome work. The purpose of the present invention is to provide a highly practical remote control device that can perform various functions.

An embodiment of this invention will be described below with reference to the drawings.

In Figure 1 a, b, c and Figure 2, 1 is the main body of the remote control device, and cable 2
It is connected to the control section of electrical equipment, such as an air conditioner. In this case, the air conditioner employs a microcomputer as a control unit and has a timer operation function for controlling operating time.
The front case 3 of the main body 1 has operation knobs 4, 5, 6, 7 for setting various operations.
A push button switch 8, an operation scale, etc. are provided. Further, pin insertion holes 11a and 11b are formed in the back case 10 of the main body 1. A shorting pin 12, which is a mounting body for testing, is inserted into the pin insertion holes 11a and 11b. The shorting pin 12 includes an insulating hand-held portion 12a, a diode 12b built into the hand-held portion 12a, and conductive pins 12c and 12d connected to both ends of the diode 12.

On the other hand, a single-sided circuit board 13 is disposed inside the main body 1, and this circuit board 13 has the above-mentioned pin insertion holes 11.
Conductive eyelets 14 at positions corresponding to a and 11b
a and 14b are fixed through each other. In this way, the eyelets 14a, 14b become the components of the timer time reduction circuit, and the eyelets 14a, 14b
By short-circuiting between them, a substantial timer time reduction circuit is formed. That is, when the shorting pin 12 is inserted and attached to the pin insertion holes 11a and 11b, the pins 12c and 12d of the shorting pin 12 are inserted into the pin insertion holes 11a and 11b.
are fitted into the eyelets 14a and 14b to form a short circuit via the diode 12b, thereby forming a timer time reduction circuit. Furthermore, various operating state setting circuits (not shown) are formed on the circuit board 13, and sliders 15 connected to the respective operation knobs..., 5,... slide into contact with these setting circuits as appropriate. It's becoming like that.

FIG. 3 shows an electric circuit formed on the circuit board 12. That is, eyelet 14a, 1
4b and the shorting pin 12 form a timer time reduction circuit for a timer on the electrical equipment (air conditioner) side. In addition, in FIG. 3, 16 is a light emitting diode for defrosting display, 17 is a light emitting diode for filter reset display, and 18 is a light emitting diode for displaying filter reset.
1 is a light emitting diode for indicating operation/stop, and furthermore, although not shown in FIG. 1a, light emitting diodes for indicating various operating states are provided.

Therefore, when testing the timer operation function, the tester can form a timer time reduction circuit by simply inserting and attaching the shorting pin 12 into the pin insertion holes 11a and 11b as shown by the arrows in FIG. and can be easily tested. In this case, since the shorting pin 12 has a diode 12b, it is necessary to ensure a certain directionality when installing it, but marks specifying the installation direction are placed on the shorting pin 12 and the pin insertion holes 11a and 11b in advance. By attaching it, you can prevent installation errors. Therefore, there is no need to provide a special short-circuit switch for testing only a few times, which does not cause design or cost problems, for example. Further, the troublesome work of connecting and disconnecting lead wires is no longer necessary, and there is no reduction in work efficiency even when testing a large number of devices. In particular, by forming the pin insertion holes 11a and 11b in the back case 10 of the main body 1, there is no problem with the design and there is no fear of dust intrusion.

In the above embodiment, a case was described in which the shorting pin 12 was used as a mounting body for testing, but there is no particular limitation on its shape, and it is not necessarily necessary to incorporate the diode 12b. Alternatively, the diode 12b may be connected to the circuit board 13 in the main body 1 in the same manner. Furthermore, since the circuit board 13 has a single-sided circuit configuration, the conductive eyelets 14a and 14b are employed, but if a double-sided circuit board is employed, the eyelets 14
a and 14b can be made unnecessary. Furthermore, although the pin insertion holes 11a and 11b are formed in the back case 10 of the main body 1, they may also be formed in the front case 3, etc. In this case, by attaching a rotary label etc. to the pin insertion holes, the design can be improved. and can solve the dust problem. Moreover, although only the test of the timer operating function has been described, it goes without saying that if this test is performed while the electrical equipment is in operation, it is possible to simultaneously test not only the timer operating function but also other parts.

As mentioned above, according to this invention, a timer time reduction circuit is formed by attaching a test mount to the main body of the device, so there is no need to provide a special switch, and moreover, it saves troublesome work. It is possible to provide a highly practical remote control device that can be used without having to perform any operations.
