Abstract

PURPOSE:To enable temperature detection which can follow a drastic change in a room temperature and prevent unnecessary temperature detection actions by executing temperature detection actions in a specified time interval and reducing temperature detection actions for a specified time starting with manipulating an operation element. CONSTITUTION:When an attempt is made to set a required room temperature with a temperature control pushbutton switch 4 and depress an operation/stop pushbutton switch 5, a code signal which conforms to a preset room temperature and a code signal which instructs operation start are transmitted to an airconditioner main body from a main body 1 of a remote control device, thereby starting operation. During this operation, CPU 10 executes temperature detection actions by a temperature read circuit 14 for a specified time interval, displays detected temperature on a liquid crystal indicator 2 in a digital manner, and transmits a code signal which conforms to the detected temperature the airconditioner main body at the same time. In this case, the time interval of operation from its start, say, 20 minutes can be reduced. For example, temperature detection action is executed per minute. When the operation has entered in steady operation mode after the lapse of 20 minutes, the temperature detection action is executed at a longer time interval, say, every 50 minutes.

Description

Detailed Description of the Invention [Object of the Invention] (Industrial Application Field) The present invention relates to a remote control device for use in an air conditioner.

(Prior art) Generally, this type of remote control device has a temperature sensor for detecting indoor temperature, and the temperature sensor performs a temperature detection operation at predetermined time intervals, and the detected temperature is displayed on a display. or send it to the air conditioner itself.

The interval between temperature detection operations is set to, for example, 5 minutes.

(Problem to be Solved by the Invention) However, when starting operation or changing settings of operating conditions, the indoor temperature changes rapidly, and the temperature detection cannot be done in time at the 5-minute interval as described above.

On the other hand, if the interval is shortened, the temperature detection operation will be performed in vain during steady operation where the indoor temperature changes slowly, resulting in an unnecessary increase in power consumption. That is, the wireless remote control device uses a battery as a power source, and saving power is important.

This invention was made in view of the above circumstances, and the first purpose is to enable appropriate temperature detection that can follow sudden changes in indoor temperature when starting operation or changing operating condition settings. It is an object of the present invention to provide a remote control device which can save power by preventing wasteful temperature detection operations.

The second objective is to enable appropriate temperature detection that can follow sudden changes in indoor temperature during start-up operations and timer-controlled operation, and to prevent unnecessary temperature detection operations to save power. The purpose is to provide a remote control device that can save money.

[Structure of the Invention] (Means for Solving the Problems) A remote control device according to claim 1 includes: a control means for performing a temperature detection operation by a temperature sensor at predetermined time intervals; and control means for shortening the interval between detection operations.

A remote control device according to a second aspect of the present invention includes a control means for performing a temperature detection operation using a temperature sensor at predetermined time intervals, and a control means for shortening the interval of the temperature detection operation for a predetermined time from the start of operation.

(Function) In the remote control device according to the first aspect, the execution timing of the temperature detection operation changes depending on the rate of change in the indoor temperature based on the operation start operation or the operation condition setting change operation.

In the remote control device according to the second aspect of the present invention, the execution timing of the temperature detection operation changes depending on how quickly the indoor temperature changes between the initial operation start by operation start operation or timer control and the other steady operation.

(Example) Hereinafter, an example of the present invention will be described with reference to the drawings.

In FIG. 2, reference numeral 1 denotes the main body of the remote control device, which has a liquid crystal display 2 and an operation lid 3 on the front, and further has a temperature setting button 4 and a start/stop button 5, which are operation devices. .

The operating lid 3 can be opened and closed, and various operating devices are provided inside.

The control circuit is shown in FIG.

Reference numeral 10 denotes a CPU (central processing unit), which performs overall control of the remote control device.

For this CPU 10, a power supply circuit 11, a key input circuit 1
2. Oscillation circuit 13, temperature reading circuit 14, code selection circuit 15, infrared LED drive circuit 16, liquid crystal display 2
Connect.

The power supply circuit 11 has a built-in alkaline battery, and the CPU
In addition to l0, power is also supplied to the infrared LEDW driving circuit 16.

The key input circuit 12 includes a temperature control button 4, a run/stop button 5,
It also detects the operation of the operating device inside the operating lid 3.

The oscillation circuit 12 provides a clock signal to the CPU10.

The temperature reading circuit 14 operates in response to an operation command from the CPU 10, reads the temperature detected by the indoor temperature sensor 17, and supplies it to the CPU 10.

The code selection circuit 15 selects a code corresponding to the output of the key input circuit 12 and the output of the temperature reading circuit 14.

The infrared LED drive circuit 16 drives an infrared LED (infrared light emitting diode) 18 in accordance with a code signal given from the CPUI O, and transmits the signal to the air conditioner main body.

Next, the operation in the above configuration will be explained.

The desired room temperature is set using the temperature adjustment button 4, and the operation/stop button 5 is pressed. Then, from main body 1 to the air conditioner main body,
A code signal corresponding to the set indoor temperature and a code signal for an operation start command are transmitted, and operation is started.

During this operation, the CPU10 executes a temperature detection operation by the temperature reading circuit 14 at predetermined time intervals, digitally displays the detected temperature on the liquid crystal display 2, and transmits a code signal corresponding to the detected temperature to the air conditioner main body. .

In this case, as shown in FIG. 3, the interval between temperature detection operations is shortened for a predetermined period of time, for example 20 minutes, after the operation start operation. For example, a temperature detection operation is performed every minute.

Note that the same execution timing is used when the operation is automatically started by timer control.

When 20 minutes have passed and steady operation begins, the interval between temperature detection operations is lengthened. For example, a temperature detection operation is performed every 5 minutes.

The air conditioner body compares the received detected temperature data with preset room temperature data received in advance, and controls the operation according to the comparison result.

In this way, at the beginning of operation based on start-up operations and timer control, the temperature detection interval is shortened, taking into consideration that the indoor temperature changes rapidly. Appropriate temperature detection that can also be followed can be performed.

In steady-state operation, the interval between temperature detection operations is lengthened in consideration of the gradual change in indoor temperature, so that unnecessary temperature detection operations can be prevented and power can be saved.

Furthermore, when the operating condition, for example, the set indoor temperature is changed using the temperature adjustment button 4 during operation, the CPU 10 transmits a code signal corresponding to the new set indoor temperature and shortens the interval between temperature detection operations.

That is, as shown in FIG. 4, the temperature detection operation is performed every minute for a predetermined period of time, for example, 5 minutes, after the setting change operation.

After 5 minutes have elapsed, the interval between temperature detection operations is increased, and temperature detection operations are performed every 5 minutes.

In this way, by shortening the interval between temperature detection operations even when operating condition settings are changed, it is possible to perform appropriate temperature detection that can follow even sudden changes in indoor temperature. In this case, the shortening period is set to 5 minutes, which is shorter than at the beginning of operation, but this takes into account that the change in indoor temperature is smaller than at the beginning of operation.
We are trying to increase the power saving effect.

By the way, a book type as shown in FIGS. 5 and 6 may be used as the main body of the remote control device.

That is, the main body 20 includes a battery storage section 21, a lid 22 that uses the battery storage section 21 as a rotation axis, and a base 23 that is connected to the battery storage section 21.

A run/stop button 24 and an operating condition setting button 25°25.25, which are operating devices, are provided on the top surface of the lid body 22.

On the top surface of the base 23, a lid closure detection switch 26 and a lighting switch 27 are provided, as well as an operating condition setting knob 28.28° 28.28, which is an operating device.
A longitudinal display plate 29.29 is provided along the knob.

The display board 29 is a transparent acrylic board, and as shown in FIG. 7, the bottom part forms an inclined reflective surface. Light emitting diodes 31 are arranged opposite to each other at both ends of the display board 29.
．． 32 is provided, and the light from those light emitting diodes is transmitted to the display board 29.
so that it is reflected upward.

The control circuit is constructed as shown in FIG. 8, except that a lighting circuit 40 is used instead of the liquid crystal display 2 of the above-described embodiment.

The illumination circuit 40 constitutes the circuit shown in FIG. 9 together with the CPU10.

That is, by applying the DC voltage Vdd to the lid closing detection switch 26 via the resistor 41, the lid closing detection switch 26
A signal obtained depending on whether the CPU10 is turned on or off is supplied to the input port of the CPU10. Applying DC voltage Vdd to the lighting switch 27 via the resistor 42, turning on the lighting switch 27,
A signal obtained in response to the off state is supplied to the input port of CPU10.

A DC voltage Vd is applied to the light emitting diode 31 through the resistor 43 and the collector-emitter of the NPN transistor 44.
d and connects the base of transistor 44 to the output port of CPU10. Light emitting diode 32 and resistor 45
A DC voltage Vdd is applied between the collector and emitter of the NPN transistor 46, and the transistor 4
6 is connected to the output port of the CPU 10.

Therefore, the main body 20 performs the following operation in addition to performing the same temperature sensing operation as in the above embodiment.

When the lid 22 is opened, the lid closure detection switch 26 is turned off.
A logic "1" signal is supplied to CPU10. In this state, when the light switch 27 is turned on, the logic “
1” signal is provided.

Since the re-input is logic "1" and the AND condition is satisfied, CPU10 outputs a logic "1" signal.

Then, transistors 44 and 46 are turned on, and light emitting diodes 31 and 32 are lit.

When the light emitting diodes 31 and 32 are turned on, their light is applied to the display plate 29, and the display plate 29 functions as a scale plate. Therefore, operating conditions can be set even in a dark room such as a bedroom.

When the lid body 22 is closed, the lid closure detection switch 26 is turned off. Then, since the AND condition for re-input is no longer satisfied, the CPU 10 sets the output to logic "0". Then, transistors 44 and 46 are turned off, and light emitting diode 3
1.32 goes out.

In other words, even if the operator forgets to turn off the lighting switch 27, the illumination of the display board 29 can be turned off by closing the lid 22. This improves battery life.

In addition, the present invention is not limited to the above-mentioned embodiments, and various modifications can be made without changing the gist.
