【発明が解決しようとする課題】
本発明は以上述べた問題点を解決し、温度センサで検出された室内温度と室外温度とから推奨設定温度を算出して表示する場合に、推奨設定温度に対する設定温度の乖離度(差)が一目でわかるものを提供することを目的とする。
【0005】
【課題を解決するための手段】
本発明は上述の課題を解決するため、室内温度を検出する室内温度センサと、室外温度を検出する室外温度センサと、リモコン装置の操作で設定される設定温度および運転モードを受信する受信部と、前記室内温度センサ、室外温度センサおよび受信部からのデータに基づいて推奨設定温度を算出すると共に、算出された推奨設定温度と前記設定温度との差を算出する制御部と、同制御部からのデータに基づき、推奨設定温度と、推奨設定温度と設定温度との乖離度を表示する表示部とを設けて構成する。
【0006】
前記乖離度の表示は、前記推奨設定温度を基準にして前記設定温度が高いか低いかを相対表示するようにする。
【0007】
なお、前記推奨設定温度は、前記表示部の中心にディジタル表示し、前記乖離度は、前記推奨設定温度を中心にして左右に形成したバーグラフ上に表示するようにしてもよい。
【0008】
前記バーグラフは、中心から左右に行くにつれてそれぞれ順次異なる発光色のものを用いるようにしてもよい。
【0009】
【発明の実施の形態】
以下、図面に基づいて本発明による空気調和機を詳細に説明する。
図1は本発明による空気調和機の一実施例を示す要部ブロック図、図2は本発明による空気調和機の動作説明のためのフローチャートである。
図1において、1は空気調和機を遠隔制御するためのリモコン装置、2は空気調和機の室内機に設けられ、室内温度を検出する室内温度センサ、3は室外機に設けられ、室外の温度を検出する室外温度センサ、4はリモコン装置1からのリモコン信号を受信する受信部、5は室内温度センサ2、室外温度センサ3および受信部4で受信されたリモコン装置1からの運転モードのデータに基づいて推奨設定温度を算出し、算出された推奨設定温度とリモコン装置1からの設定温度との差を算出する制御部、6は制御部5からのデータに基づいて推奨設定温度と、推奨設定温度と設定温度との乖離度を表示する表示部で、同表示部6は受信部4や制御部5と共に室内機に付設されている。図3は表示部6の一例で、中央に推奨設定温度をディジタル表示するための7セグメント表示器を設け、その左右に推奨設定温度に対する使用者の設定した設定温度の高低を相対表示するバーグラフ用の表示器(例えば、LEDを用いる)を配置している。
【0010】
以上の構成において、その動作を図2のフローチャートを用いて説明する。
空気調和機はリモコン装置1の操作等で運転開始のリモコン信号が発信されたとき受信部4でこれを受信する。この受信に応動し、室内温度センサ2で室内の温度を検出し(ステップ1、以降、ST1と略す)、室外温度センサ3で室外の温度を検出し(ST2)、使用者によって設定されたリモコン装置1からの運転モードと設定温度のリモコン信号を受信部4で受信する(ST3)。室内温度センサ2および室外温度センサ3で検出された温度データ、および受信部4で受信されたデータは制御部5に入力され、同制御部5により、室内温度(例えば、30℃)と室外温度(例えば、33℃)と運転モード(例えば、冷房運転)とに基づいて推奨設定温度(例えば、28℃)を算出し(ST4)、次いで、推奨設定温度(前記28℃)と設定温度(例えば、26℃)の差(−2℃)を算出する(ST5)。算出されたデータは表示部6に入力し表示する(ST6)。すなわち、図3に示す如く、中央の7セグメント表示器で推奨設定温度「28℃」をディジタル表示し、設定温度は左方の「−2℃」のバーグラフ(LED)を点灯する。
【0011】
これにより、使用者は自分の設定した温度が26℃であるのに対して空気調和機内で算出される推奨設定温度が28℃であり、省エネルギーの観点や健康面からすれば設定温度が約2℃低いことがわかるので、これを無視してこのまま運転を続けるか、推奨に従って設定温度を上げるか等を選択することができる。
【0012】
なお、表示部6のバーグラフは、例えば、LEDを用い、推奨設定温度に比べて設定温度が低い場合の−1℃、−2℃、−3℃の表示用と、推奨設定温度に比べて設定温度が高い場合の+1℃、+2℃、+3℃の表示用を設ける。そして、中心から左右に行くにつれてそれぞれ順次異なる発光色、例えば、中心寄りから設定温度の高い方(右方)を順次黄色、橙色、赤色等とし、設定温度の低い方(左方)を順次緑色、空色、青色等とし、自分の設定した温度が推奨設定温度に比べてどれくらい高いか低いかを色で判断できるようにしてもよい。
なお、本願は空気調和機を例として説明しているが、これに限るものではなく、例えば、温水暖房機やガス冷暖房機等、温度管理を行っている他の製品にも適用可能である。
【0013】
【発明の効果】
以上に説明したように、本発明による空気調和機によれば、温度センサで検出される室内温度、室外温度と、使用者が設定した運転モードとから推奨設定温度を算出し、さらに、推奨設定温度と設定温度の差(乖離度)を算出し、これら推奨設定温度、および推奨設定温度と設定温度の乖離度を室内機の表示部に表示するもので、推奨設定温度は中央に7セグメント表示器等でディジタル表示し、推奨設定温度と設定温度の乖離度は7セグメント表示器の左右にLED等を用いてバーグラフ式に表示する。これにより、使用者は自分の設定した温度が推奨設定温度に比べてどれくらい高いか低いかが一目でわかるので、例えば、冷房運転の際に不用意に室外温度より異常に低い温度に設定するのを避けることができ、また、このまま運転を続けるか、推奨に従って設定温度を設定しなおすか等を健康面や省エネルギー運転の観点から選択することができる。なお、バーグラフは、中心から左右に行くにつれて順次発光色を変えることにより乖離度がわかりやすくなり、なお一層使いやすいものとなる。

BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, an air conditioner according to the present invention will be described in detail with reference to the drawings.
FIG. 1 is a block diagram showing a main part of an embodiment of an air conditioner according to the present invention, and FIG. 2 is a flowchart for explaining the operation of the air conditioner according to the present invention.
In FIG. 1, reference numeral 1 denotes a remote control device for remotely controlling an air conditioner, 2 denotes an indoor temperature sensor that is provided in an indoor unit of the air conditioner and detects an indoor temperature, and 3 denotes an indoor temperature sensor that is provided in an outdoor unit. Temperature sensor 4 for detecting the remote control signal from the remote control device 1, a receiving unit 5 for receiving a remote control signal from the remote control device 1, and operation mode data from the remote control device 1 received by the indoor temperature sensor 2, the outdoor temperature sensor 3 and the receiving unit 4 The control unit 6 calculates a recommended set temperature based on the data, and calculates a difference between the calculated recommended set temperature and the set temperature from the remote control device 1. The display unit 6 displays the degree of divergence between the set temperature and the set temperature. The display unit 6 is attached to the indoor unit together with the reception unit 4 and the control unit 5. FIG. 3 shows an example of the display unit 6, in which a 7-segment display for digitally displaying the recommended set temperature is provided at the center, and a bar graph on the left and right of which indicates the relative level of the set temperature set by the user with respect to the recommended set temperature. (For example, using an LED).
[0010]
The operation of the above configuration will be described with reference to the flowchart of FIG.
In the air conditioner, when a remote control signal for starting operation is transmitted by operation of the remote control device 1 or the like, the receiving unit 4 receives the signal. In response to this reception, the indoor temperature sensor 2 detects the indoor temperature (step 1, hereinafter abbreviated as ST1), the outdoor temperature sensor 3 detects the outdoor temperature (ST2), and the remote controller set by the user. The receiving unit 4 receives the remote control signal of the operation mode and the set temperature from the device 1 (ST3). The temperature data detected by the indoor temperature sensor 2 and the outdoor temperature sensor 3 and the data received by the receiving unit 4 are input to the control unit 5, and the control unit 5 controls the indoor temperature (for example, 30 ° C.) and the outdoor temperature. A recommended set temperature (for example, 28 ° C.) is calculated based on (for example, 33 ° C.) and an operation mode (for example, cooling operation) (ST4), and then a recommended set temperature (for example, 28 ° C.) and a set temperature (for example, 28 ° C.). , 26 ° C.) (−2 ° C.) (ST5). The calculated data is input to the display unit 6 and displayed (ST6). That is, as shown in FIG. 3, the recommended set temperature “28 ° C.” is digitally displayed on the central 7-segment display, and the bar graph (LED) of “−2 ° C.” on the left of the set temperature is turned on.
[0011]
As a result, the user sets the recommended temperature calculated in the air conditioner to 28 ° C. while the temperature set by the user is 26 ° C. From the viewpoint of energy saving and health, the set temperature is about 2 ° C. Since it is known that the temperature is lower by ° C., it is possible to select whether to ignore this and continue the operation as it is or to increase the set temperature according to the recommendation.
[0012]
In addition, the bar graph of the display part 6 uses, for example, an LED, for displaying −1 ° C., −2 ° C., and −3 ° C. when the set temperature is lower than the recommended set temperature, and for comparing with the recommended set temperature. A display for + 1 ° C, + 2 ° C, and + 3 ° C when the set temperature is high is provided. Then, as the color goes from the center to the left and right, the emission colors sequentially differ, for example, yellow, orange, red, etc., sequentially with the higher set temperature (right) from the center, and green with the lower set temperature (left). , Sky blue, blue, or the like, and it may be possible to determine by color how much higher or lower the temperature set by the user is than the recommended set temperature.
Although the present application describes an air conditioner as an example, the present invention is not limited to this. For example, the present invention can be applied to other products that perform temperature management, such as a hot water heater and a gas cooler / heater.
[0013]
【The invention's effect】
As described above, according to the air conditioner of the present invention, the recommended set temperature is calculated from the indoor temperature, the outdoor temperature detected by the temperature sensor, and the operation mode set by the user, and further, the recommended setting is performed. The difference (degree of deviation) between the temperature and the set temperature is calculated, and the recommended set temperature and the degree of divergence between the recommended set temperature and the set temperature are displayed on the display unit of the indoor unit. Digital display is performed by a display or the like, and the divergence between the recommended set temperature and the set temperature is displayed in the form of a bar graph using LEDs or the like on the left and right of the 7-segment display. As a result, the user can see at a glance how high or low the temperature set by himself / herself is higher than the recommended set temperature.For example, when the cooling operation is performed, carelessly setting the temperature abnormally lower than the outdoor temperature can be avoided. It can be avoided, and it is possible to select whether to continue the operation as it is or to reset the set temperature according to the recommendation from the viewpoint of health and energy saving operation. The divergence of the bar graph is easily changed by sequentially changing the emission color as going from the center to the left and right, so that the bar graph becomes even easier to use.
