Description

[Detailed description of the invention] This invention describes how much electricity can be saved when using an air conditioner, for example, if power-saving operations are performed during cooling, compared to normal cooling without such controls. This invention relates to a power saving display device for an air conditioner, in which a display device that visually indicates whether the air conditioner is being operated is attached to the air conditioner.

Conventionally, many display devices that indicate the operating status of an air conditioner display, for example, whether the compressor is in operation or the current temperature in the air conditioner room.

Recently, as energy resources have become expensive and there has been a desire to save energy, air conditioners are often equipped with various energy-saving control circuits.

In view of the above points, the present invention is suitable for implementation in such cases.The purpose of the present invention is to display the energy saving status of the air conditioner during operation, to inform the user of the energy saving status, and to save electricity and save money. An object of the present invention is to provide a power saving display device for an air conditioner that can satisfy economic considerations.

In order to achieve this objective, the present invention provides a plurality of light emitting displays divided into sizes approximately proportional to the power saving rate of each power saving control means that can control the operation of an air conditioner and save power in multiple ways. It is provided with a divided display means consisting of elements, and the divided display means can be blinked or dimmed in conjunction with the operation of the power saving control means.

Hereinafter, embodiments of the present invention will be described in detail based on the drawings.

FIG. 1 is a diagram showing a display section of the present invention, and FIG. 2 is an electric circuit diagram constituting the present invention.

In Figure 1, a plurality of L's are made to emit light in a planar manner.
Light emitting display elements (hereinafter abbreviated as light emitting elements) 1 to 4 such as EDs or liquid crystals are divided into arcs and arranged so that they all form a circular pie chart.

For example, the entire light emitting element constitutes a substantially complete circle, and the light emitting element 1,
2 and 3 are each divided into 10% circular arcs, and the light emitting element 4 is divided into 70% circular arcs, making a total of 100%, which is approximately the entire circle.

Each of these display elements 1 to 4 constitutes a divided display means that is divided and arranged in a size approximately proportional to the electrical conductivity of the power saving control means.

In FIG. 2, a first operation switch 23 for the purpose of power saving and a second operation switch 2 for the purpose of power saving are also shown.
4, a first detector 25 such as a thermistor element that detects the air temperature inside the room to be air-conditioned, and a second detector 25 such as a thermistor element that similarly detects the outdoor air temperature of the room to be air-conditioned. 26 are connected in parallel to the microcomputer LSI 20 as inputs.

For example, a program store sequential type one-chip microcomputer 6*20 (hereinafter referred to as LSI) has multiple outputs, one of which is sent to a display buffer 20.
and the other is a buffer 2 for a switch that controls the power of a drive unit component such as a compressor of an air conditioner or a fan motor, such as a relay.
Connected to 2.

Then, the output of the buffer 21 is the light emitting element 1 to 4.
The output of the buffer 22 can be used, for example, for a switch coil 29 for an air conditioner's compressor, a switch coil 28 for an indoor blower, or a solenoid valve switch for saving capacity in a refrigerant circuit. The coils 27 are connected in parallel so that they can be turned on and off.

The operation of the present invention will be explained below based on FIGS. 1 and 2.

It is now assumed that all of the light emitting elements 1 to 4 are lit during normal operation of the air conditioner.

For example, if the operation switch 23 is turned on for the purpose of first power saving, which operates a circuit that keeps the humidity low and raises the set room temperature by that amount, then the input 6■20 outputs a signal to the buffer 21 to turn off the light emitting element 1 based on a pre-programmed sequence, and outputs a signal to the buffer 22 to send a signal to the compressor relay coil 29 and indoor fan motor relay coil 28 to operate the compressor and indoor fan, for example. By causing a time lag in the mode, a signal is output to keep the humidity low and perform power-saving control such as raising the indoor temperature by about 1°C and operating the air conditioner.

Furthermore, when the operation switch 24 for the purpose of second power saving, such as a capacity saving circuit, is turned on, the light emitting element 2 is turned off in the same manner as described above, and the capacity saving electromagnetic valve coil 27 is switched on, for example, to reduce the cooling capacity. An on or off signal is output to save power.

In addition, as a third power saving purpose, for example, the first detector 25 detects the indoor fixed temperature and the second detector 25 detects the outdoor air temperature.
When the value of the temperature detected by the detector 26 is above a certain value, for example, when the outdoor air temperature is higher than about 5°C, the operating rate of the compressor is increased by increasing the indoor air nodal temperature by 1°C and performing cooling operation. The LSI 20 determines to reduce the power consumption and perform power-saving operation, and outputs a signal to the buffer 21 to turn off the light emitting element 3.

As a result of these actions, as the control corresponding to each of the first to third power saving objectives is carried out sequentially, the display section in Figure 1A turns off the light in parts of the circumference and displays the amount of power saved during the current operation of the air conditioner. can be visually displayed and announced.

For example, when the first to third power-saving controls are performed, LEDs 1 to 3 are turned off, only LED 4 is lit, and the pie chart display indicates that the air conditioner is operating at 70% of the normal power consumption. Indicates that

As an application of the present invention, the amount of electricity saved can be expressed even more realistically by displaying the amount of electricity at each time in monetary terms on the dividing tangent line of the display section.

Furthermore, the same effect as described above can be obtained by arranging the display section divided into bar shapes and turning off the light in each section by power saving control, or by dimming the light emitting elements of the divided display section without turning off the light. You can.
