Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to an air conditioner, and particularly to improvements in a temperature display device and an operation display device thereof.

[Prior art]

Conventionally, this type of air conditioner has been equipped with an automatic temperature controller to appropriately adjust the room temperature, and a neon lamp to display the operating status.

An air conditioner equipped with such a display device allows users to set the dial of the automatic temperature controller to any desired position in order to maintain a temperature that is comfortable for the user, and to turn the dial off when the air conditioner is running. In addition to lighting the indicator lamp, once the room temperature has been adjusted to the set temperature, the operation indicator lamp is turned off by the operation of the automatic temperature controller.

However, in the temperature display and operation display device of such an air conditioner, it is not possible to know what the set temperature and room temperature are, and the appropriate temperature can be found indirectly by referring to the number on the dial of the automatic temperature controller. This makes it extremely difficult to set the temperature to match the time, changes in outside temperature, the condition of the user, and the initial room temperature. It has drawbacks such as being extremely undesirable from the standpoint of omitted energy.

[Summary of the invention]

In order to eliminate such drawbacks, this invention
To provide an air conditioner which is equipped with a temperature display part on the air conditioner body, can always display the set temperature and the room temperature if there is a difference between the temperatures, and can easily notify the operating status. This is the purpose.

[Embodiments of the invention]

The present invention will be explained in detail below with reference to illustrated embodiments. In FIG. 1, reference numeral 1 indicates an indoor main body of a separate air conditioner, and reference numeral 2 indicates a temperature display section having a plurality of temperature display lamps 3, which is provided on the front surface of the main body 1.
Reference numeral 4 denotes a control device for controlling the lighting of the indicator lamp 3, which connects a room temperature detector having a thermistor 5 etc. disposed in the air suction section (not shown) of the main body 1 and the temperature display section 2 with electricity. connected. Reference numeral 6 denotes a remote control section, which incorporates a room temperature setting device having a temperature adjustment volume 8 provided with a knob 7 as a temperature setting operation means, and is electrically connected to the control device 4.

At this time, the room temperature is sensed by the thermistor 5 in the air suction section of the main body 1, the same temperature as this temperature is displayed on one of the temperature display lamps 3, and the set temperature is determined by the temperature adjustment volume 8 on the remote control section 6.
Similarly, one of the temperature display lamps 3 displays the temperature corresponding to the set position.

In such a case, if there is a difference between the temperatures, the room temperature and set temperature should always be displayed independently. For example, the room temperature should be displayed as a dimming point at regular intervals, and the set temperature should be displayed constantly. ,
The display format of room temperature and set temperature is changed to make it easier to distinguish between the two.

To explain the operation of the air conditioner configured in this way, for example, when the indoor temperature is 30°C, the knob 7 of the temperature control volume 8 is set to the "4" position and the air conditioner 1 is operated for cooling. Start. Immediately after starting, thermistor 5 detects the room temperature,
The temperature display lamp 3 indicating the position of 30°C starts to dim.
Also, the set temperature is 27°C, which corresponds to the temperature display lamp 3 corresponding to the "4" position of the temperature control volume 8.
lights up.

After that, as the room temperature decreases, the temperature rises to 29℃.
When the temperature reaches 30°C, the lamp 3 indicating the 30°C position is dimmed.

In this way, when the room temperature is further lowered and reaches 27°C, which is the same as the set position of the temperature control volume 8, the control device 4 transmits the information to the outdoor main body (not shown) and compressor (not shown). At the same time, in order to match the display form of the room temperature and the set temperature, only one lamp 3 indicating the 27°C position is turned on. 27℃
Let them know that they are kept in good condition. Then, after a certain period of time has elapsed, as the room temperature rises, the cooling operation is restarted and the lamps 3 corresponding to the rising temperature are dimmed.

An example of a control device that performs the above-mentioned operations is shown in FIG. 2 and will be briefly described. 40A,
40B is a window comparator group, which is composed of multiple window comparators that generate temperature signals in 1°C units from 24°C to 30°C, and each window comparator is An output (H level) is output only to the window comparator where the room temperature voltage input from the room temperature detector 5 is within the voltage value corresponding to ±0.5° C. to the AND circuit and the OR circuit. Reference numeral 41 denotes a voltage match comparison circuit, which compares the room temperature voltage value from the room temperature detector 5 and the set temperature voltage value from the room temperature setter, and if they match, outputs a match output (H level) to the output terminal 42, and if there is a mismatch, it outputs a match output (H level) to the output terminal 42. In this case, a mismatch output (H level) is output to the output terminal 43.

Note that an intermittent pulse for changing the display form is input to the input terminal 44 of the AND circuit 45.

Here, the operation of the device shown in FIG. 2 will be briefly explained. First, when the room temperature is 30°C and the set temperature is 27°C, the detected voltage value from the room temperature detector 5 is outputted at H level only for the comparator to which the 30°C reference voltage of the window comparator group 40A is input, and one side of the AND circuit is output. given to. On the other hand, the output terminal 43 of the voltage coincidence comparison circuit 41 has a mismatch output (H
level) is generated, AND is taken with the intermittent pulse input from the input terminal 44, and the signal is ANDed through the OR circuit.
given to the other side of the circuit. Therefore, lamps that are compatible with 30°C will turn off. Also, the set temperature voltage value from the room temperature setting device 6 is determined by the comparator group 4.
H level is output only for the comparator to which the 0B 27℃ reference voltage is input, and the output is output via the OR circuit.
The 27℃ lamp will be lit continuously.

Note that when the room temperature and the set temperature match, the output terminal 43 of the comparison circuit 41 becomes L level and the output terminal 42 becomes H level, so the intermittent pulse is
It will be turned off and only the 27℃ lamp will be lit continuously.

As explained above, the control device can be constructed with a simple circuit as shown in Fig. 2, and it is obvious that program control using a microcomputer is also possible in addition to such a circuit. The present invention is not limited to these examples.

〔Effect of the invention〕

The present invention is constructed as described above, and a room temperature detector such as a thermistor that senses the room temperature and a room temperature setting device such as a temperature control volume that determines the set temperature are electrically connected to a control device. Furthermore, by electrically connecting the temperature display unit that displays room temperature and set temperature to the control device, it is possible to display the room temperature and set temperature when there is a difference between them and when the air conditioner is in operation, and when the room temperature and set temperature are different. Since the display format is changed on the temperature display section to indicate when the air conditioner is stopped and the air conditioner is stopped, the user can always visually recognize the two cases, and also when the room temperature and set If the temperature matches, the cooling operation will stop, so you can be notified at the same time whether it is running or not, which prevents the room temperature from dropping too low or rising too high, and is also effective in terms of energy conservation.

It should be noted that although the above explanation has been given using an example of cooling, it goes without saying that the same method can be used for heating.
