【發明內容】 現在’省電源意識的高漲，在遙控器也被要求裝載延 長電池壽命的功能，安全又清潔的電力的供應源。 藉由進行倂用在專利文獻1所揭示的太陽電池與內設 的鋰電池’來延長鋰電池的電池壽命的方式，是在遙控器 也爲有效的手段。 但是’在以專利文獻1所揭示的方式中，在太陽電池 與鋰電池的雙方具備電壓檢測電路之故，因而藉由電壓檢 測電路雖些微也會消耗常時電力。 又’在以專利文獻1所揭示的方式，裝載著充分大的 太陽電池，而在白天光亮的時間帶成爲從太陽電池可供應 所有電力，惟如遙控器地考慮顧客的方便性，而有期盼小 型的機器上可裝載太陽電池的面積上有限制。所以無法將 維持遙控器的通訊時所必需的大電流的充分大的面積的太 -6 - 201110505 陽電池無法裝載於遙控器。 專利文獻2是藉由太陽電池進行乾電池的補助，而且 具備在需要大電流的通訊時將電源從太陽電池轉換至乾電 池的電源供應線路轉換手段，延長乾電池的壽命者，惟需 要轉換電源供應線路所用的電路與檢測出電源電壓的電 路，使得全體的電路構成成爲複雜的缺點問題。又，藉由 檢測出電源電壓的電路會產生多餘的電力消耗的缺點問題 是與專利文獻1同樣。 太陽電池的發電量是比例於照度而增加之故，因而在 照度大的條件下，可容易地想像太陽電池的輸出電壓超過 乾電池的端子電壓。若太陽電池的輸出電壓超過乾電池的 端子電壓，而將轉換電源供應線路所用的電路構成作爲電 子式開關[例如使用FET(Field Effect Transistor)的開關電 路]時，藉由洩漏電流有充電電流從太陽電池流至乾電 池。乾電池是依種類有所不同惟只容許微量的充電電流， 尤其是，針對於鹼性乾電池或錳乾電池並不容許所有充電 電流。充電電流流入至乾電池，是誘發乾電池的洩漏液 體，而有污損遙控器的可能性。 又，藉由將轉換電源供應線路所用的電路構成作爲機 械式開關就可防止洩漏電流。但是，在轉換電源供應線路 時從任一電池都發生未能供應電源之狀態，而有因瞬間地 降低電力而在遙控器產生錯誤動作之虞，或是每當發訊時 起因於機械式開關轉換所用的機械式開關的耐久性的遙控 器的降低壽命，或在開關元件的小型化上有界限等的缺點 201110505 問題。 專利文獻3是隨著攜帶機器的小型化，使得能量密度 高的電池的使用用途會擴大，惟能量密度高的電池是與鋰 電池相比較，電壓變化率較大，而使用昇降壓變頻器來實 現電壓的穩定化（定電壓化）者。 如該專利文獻3所示地，爲了提昇攜帶機器的電路的 穏定性，考量進行定電壓化的方式是有效果。又，在達到 電池的終止電壓之後才使用昇降壓變頻器以昇壓電壓，而 實現電池的長壽命化的方式是可實現高效果，電池的長壽 命化。 但是，有關於以單體電池所使用的機器上有效，惟如 本發明，組合太陽電池與太陽電池以外的其他電池加以使 用的電路，其他電池降壓時，藉由漏流會有充電電流流在 其他電流之故，因而產生與上述的專利文獻2同樣的問 題。 這樣，本發明是提供一種可實現穩定的使用性與長壽 命化的遙控器作爲課題。 本發明是爲了解決此些課題，申請專利範圍第1項的 •一種遙控器，屬於倂用太陽電池與其他電池而將電力供應

此外，在室內機2的化粧框23，具備室內機發送接收 部231，及室內機顯示裝置2 3 2。 室內機發送接收部231是可接收由遙控器4所發送的 紅外線訊號，成爲藉由從遙控器4所發送的紅外線訊號可 進行空調機1的操作的構成。又’室內機發送接收部23 1 是可將紅外線訊號發送至遙控器4。 室內機顯示裝置23 2是顯示空調機1的動作狀態。 <遙控器的構成> -10- 201110505

如第4圖所示地’在遙控器4的背面裝設有可裝卸的 -11 - 201110505 乾電池承窩蓋4 1 1 » 又，如第5圖所示地，具備：當拆下乾電池承窩蓋 411，轉換供應於遙控器4的電池轉換開關421，及將電源 供應於遙控器4所用乾電池（未予圖示）予以插入所用的乾 電池承窩422，及與乾電池電性地連接的電池連接端子 42 3 ° 第6圖是本實施形態的遙控器的外觀右側視圖，第7 圖是本實施形態的遙控器的側面斷面模式圖。 如第6圖所示地，遙控器4是在背面中央部形成有置 放手指部4 2 7。 如第7圖所示地，將電源供應於遙控器4的鋰一次電 池43 1，是裝備於遙控器4的內部而成爲無法從外部容易 地取出的構造。又，在遙控器4的乾電池承窩422封入有 下述的注意牌子428。 <遙控器的電路構成> 以下，針對於本實施形態的遙控器4的電路構成，使 用第8圖及第9圖加以說明。 第8圖是未具備比較例的太陽電池的遙控器的電路模 式圖。 表示於第8圖的比較例的遙控器的電路是具備：作爲 電源的乾電池432，及微電腦440，及發送電路441，及 LCD403，及操作按鈕404。 乾電池43 2是將電源供應於發送電路441及微電腦 -12- 201110505 440，而且經由微電腦44〇也將電源供應东 微電腦440是將以操作按鈕4〇4所操 動作指示接受作爲電性訊號，製作發送至

過乾電池的端子電壓。當太陽電池的輸出 的端子電壓，則充電電流會從太陽電池流 降低乾電池的安全性，或誘發乾電池的漏 之虞。 第9圖是本實施形態的遙控器的電路 本實施形態的遙控器4的電路是除了 的電路（參照第8圖）以外，還具備： 451，及具旁路的昇壓電路452，及二極 及調整器456，及充電用電容器457，及；{ 將乾電池43 2(參照第8圖）變更成鋰一次胃 > LCD403。 作的空調機1的

5a的陰極側與二極 體455b的陰極側相連接的方式，由相對配置的兩個二極 體45 5a，455b所構成的電路。 亦即，二極體”或”電路45 5是針對於二極體45 5 a的 陽極側的電壓與二極體45 5b的陽極側的電壓，電流從電 壓高側流動的電路。 又，二極體45 5 a的陽極側是被連接於將後述的鋰一 次電池43 1作爲供應源的電源供應電路。一方面，二極體 45 5b的陽極側是被連接於將後述的太陽電池402作爲供應 源的電源供應電路。又，二極體45 5 a，45 5b的陰極側是 被連接於作爲負荷的微電腦440。藉此，電源從以二極體” 或"電路45 5所選擇的電源供應電路供應至微電腦440。 <將太陽電池作爲供應源的電源供應電路> 首先，針對於將被連接於二極體"或"電路455的二極 體45 5b的陽極側的太陽電池402作爲供應源的電源供應 電路加以說明。 太陽電池402的輸出電壓是藉由照度有所變更。通 常，遙控器4是以室內照度被使用作爲前提來設計太陽電 池4 02之故，因而當接觸到如太陽光地強烈光，會使得太 陽電池40 2的輸出電壓上昇，而藉由高電壓會破壞微電腦 44 0或電路元件之虞。 -14- 201110505 所以，將太陽電池402作爲供應源的電源供應電路， 是在太陽電池402與二極體45 5b的陽極側之間配置調整 器456，成爲限制供應於微電腦440等的電壓上限値而確 保安全性的電路構成。 又，調整器456的限制電壓，是比從後述的鋰一次電 池431的端子電壓（約3.2V)考慮防止逆流二極體451的壓 降（例如0.4V)的數値（亦即，2.8V)還要大，且被設計成不 會破壞微電腦440等的電壓値（例如，3.0V)。 又，在太陽電池402，是連接有可蓄電太陽電池402 的電力的電性雙重層電容器所構成的充電用電容器457。 藉由具備充電用電容器457，將太陽電池402作爲供 應源的電源供應電路，是即使藉由開閉窗簾或室內燈的點 燈，熄燈變更室內照度時，或是歪斜遙控器4時等所產生 的強度變化所致的太陽電池402的輸出電壓的變動，也可 提昇電源供應的穩定性。又，在供應至負荷的電流少的狀 態下，即使太陽電池402的輸出電壓小時，在某一定時 間’也可以以被蓄積在充電用電容器45 7的電力電源供應 至負荷。 <將鋰一次電池作爲供應源的電源供應電路> 以下，針對於將被連接於二極體"或"電路455的二極 體455a的陽極側的鋰一次電池431作爲供應源的電源供 應電路加以說明。 經由二極體”或”電路45 5作爲與太陽電池402，充電 •15- 201110505 用電容器45 7連接的電路構成時，必須解決以下的缺點問 題。亦即，若有充分照度時，則太陽電池402及充電用電 容器457的電壓比鋰一次電池431變高，而二極體455a 的陰極側的電壓比二極體455a的陽極側的電壓變高。所 以，在二極體45 5a發生漏流，而漏流是作爲鋰一次電池 431的充電電流流動。鋰一次電池431是容許少量的充電 電流，惟在容許的充電電流上有所限制，必須儘可能減小 充電電流。 通常，爲了防止逆電流將低漏流性的防止逆流二極體 45 1插入在電路上加以使用。但是，低漏流性的防止逆流 二極體451是壓降大之故，因而會降低來自鋰一次電池 4 3 1的供應電壓。 亦即，鋰一次電池431的端子電壓是約3.2V左右， 對此，藉由防止逆流二極體4 5 1，例如發生約0.4 V的壓 降，成爲來自鋰一次電池 431的供應電壓是成爲大約 2.8V。在此，若將微電腦440的驅動電壓作爲2.5V時， 則即使在插入防止逆流二極體45 1的狀態下，微電腦440 是也正常地驅動。但是，在鋰一次電池43 1的端子電壓降 低至2.8V的時刻，則來自鋰—次電池431的供應電壓是 成爲大約2.4V而有無法正常地起動微電腦440之虞。 如此地，即使鋰一次電池43 1的端子電壓比微電腦 440的驅動電壓還要高時，藉由防止逆流二極體451的壓 降’鋰一次電池43 1是也無法將電源供應於微電腦440。 換言之’會顯著地降低鋰一次電池43 1的有效使用期間。 -16- 201110505 又，發送電路44 1是在發送時流著500mA左右的大 電流之故，因而在流著大電流的瞬間地降低鋰一次電池 43 1的端子電壓。藉此，供應電壓至微電腦440瞬間地降 低，而有產生微電腦440被復置的LCD4〇3的顯示瞬間地 變薄等的不方便之虞。 於是，本實施形態的遙控器4，是在將鋰一次電池 431作爲供應源的電源供應電路插入昇壓電路45 3 (具旁路 的昇壓電路452)就可解決。 具旁路的昇壓電路452是與昇壓電路45 3並聯地配置 旁路用二極體454所構成的電路。又，昇壓電路45 3的輸 出電壓是可確保微電腦440的驅動電壓（例如，2.5V)，且 被設定在比調整器45 6的限制電壓（例如3.0V)還要低的電 壓（例如2.6 V)。 具旁路的昇壓電路452是在輸入電壓超過昇壓電路 453的輸出電壓的狀態下（例如鋰一次電池的初期狀態下， 鋰一次電池的端子電壓爲3.2V，而輸入電壓成爲2.8V的 狀態），經由並聯地配置的旁路用二極體454而可供應電 源之故，因而停止昇壓電路45 3，而可減低在昇壓電路 453的耗電。 —般，在輸出電壓具不會下降至電流容量的約80%附 近的特性的鋰一次電池43 1，其效果是更大，使用期間的 大約80%是不必將昇壓電路453予以動作就可使用。 —方面，具旁路的昇壓電路452，是在輸入電壓低於 昇壓電路453的輸出電壓的狀態下（例如，鋰一次電池的 -17- 201110505 端子電壓降低至2.8V，而輸入電壓成爲2.4V的狀態），藉 由昇壓電路45 3被昇壓而可確保微電腦440的驅動電壓。 藉此，將鋰一次電池43 1作爲供應源的電源供應電路，是 可提昇電源供應的穩定性，信賴性。 又，鋰一次電池43 1藉由放電使得端子電壓降低，即 使成爲比微電腦的驅動電壓還要低的狀態時，也藉由昇壓 電路45 3被昇壓而可確保微電腦44 0的驅動電壓。藉此， 成爲儘量地延長使用鋰一次電池431，而可達成長壽命 化。 如此地，具旁路的昇壓電路452，是藉由並聯地配置 旁路用二極體454，成爲可減低爲了提昇穩定性與信賴性 所配置的昇壓電路453的缺點的昇壓電路453的耗電，而 可達成鋰一次電池4 3 1的長壽命化。 又，將昇壓電路453的方式使用頻率變動型的昇壓方 式’在昇壓率低時，將頻率作成低就可減小在昇壓電路 453的耗電之故，因而比變動任務方式的昇壓電路成爲可 更抑制耗電。 如此地，藉由在頻率變動型昇壓電路453並聯地設置 旁路用二極體454，經常地可確保電路的穩定性，惟遙控 器的使用期間的大部分，是不使用昇壓電路454之故，因 而同時地可達成遙控器的穩定動作與電池長壽命化。 (發送電路） 發送電路441是在發送時瞬間地需要大電流的負荷。 -18- 201110505 然而，太陽電池402是設置於遙控器4的表面（參照 第2圖），惟遙控器4是若考慮使用者的方便性則期盼爲 小型，又，在遙控器4的正面，配置有操作按鈕404, LCD403。所以可配置太陽電池402的面積是有限，而在 以太陽電池4 0 2作爲供應源的電源供應電路所供應的電流 量有限度。 因此，如第9圖所示地，以太陽電池402作成供應源 的電源供應電路是電源供應於不需要大電流的微電腦440 或LCD403，而瞬間地需要大電流的發送電路441是作成 從鋰一次電池43 1直接接受電源供應的構成較佳。 藉此，可強化對於遙控器4的負荷的電源供應的穩 定。 又，遙控器4是分別成爲操作按鈕404被操作而爲了 發送紅外線訊號需要大電流的發送狀態，及不需要大電流 的僅驅動微電腦44〇或LCD403的待機狀態。在此，遙控 器4是並不是頻繁地操作者，待機狀態的期間與發送狀態 的期間相比較較久。 如此地，將遙控器4設計成以太陽電池402可維持待 機狀態的電力就可以。 藉此，室內照度爲發電上充分時，則待機狀態的電源 供應是從以太陽電池402作爲供應源的電源供應電路所供 應，可抑制鋰一次電池43 1的耗電，而可達成遙控器4的 長壽命化。 又’若作成由操作按鈕4 0 4的操作在所定時間後熄燈 -19- 201110505 LCD403的構成，貝IJ更可達成省電力化與長壽命化。 <對微電腦的電源供應> 針對於遙控器4的各狀態的電源供應分別加以說弓 首先，針對於遙控器4爲待機狀態，且遙控器4 太陽電池402的照度爲維持待機狀態的電力上充分的 (例如200米燭光）加以說明。 這時候從以太陽電池402作爲供應源的電源供應 所供應的電壓（3.0V)，比從以鋰一次電池43 1作爲供 的電源供應電路所供應的電壓（2.6 V〜2.8 V)還要高。 所以，藉由二極體"或”電路455，以從太陽電池 作爲供應源的電源供應電路被電源供應於微電腦440。 以下，針對於遙控器4仍爲待機狀態，而遙控器 於太陽電池402的照度變小時加以說明。 此時，利用太陽電池402所發電的電壓是降低， 由被蓄積在充電用電容器45 7的電壓，從以太陽電池 作爲供應源的電源供應電路的電壓，是某一定時間維 以鋰一次電池4 3 1作爲供應源的電源供應電路所供應 壓（2.6V〜2.8V)還要高的狀態。 所以，藉由二極體”或”電路4 5 5，以從太陽電池 作爲供應源的電源供應電路被電源供應於微電腦440。 之後，藉由將電流從充電用電容器45 7繼續供應 電腦440，充電用電容器45 7的電壓是會減少。亦即 陽電池4 0 2作爲供應源的電源供應電路所供應的電壓 對於 情形 電路 應源 402 4對 惟藉 402 持比 的電 402 至微 從太 會減 -20- 201110505 少〇 以從太陽電池402作爲供應源的電源供應電路 的電壓比以從鋰一次電池43 1作爲供應源的電源供 所供應的電壓還要小，則藉由二極體"或"電路455 一次電池43 1作爲供應源的電源供應電路電源供應 腦 44 0。 如此地，轉換以太陽電池402作爲供應源的電 電路與以鋰一次電池43 1作爲供應源的電源供應電 由二極體"或"電路45 5所進行，不必具備監視各該 用的電壓檢測電路，而可簡化電路。 又，電壓檢測電路是即使未被選擇作爲將電源 負荷的電路時也經常耗電，所以，未具備鋰一次電 的電壓檢測電路的本實施形態的遙控器4，是與具 檢測電路的電路相比較，可實現鋰一次電池43 1 命。 此外，也不必具備太陽電池402的電壓檢測 故，因而成爲可抑制待機狀態的耗電。藉此，與具 檢測電路的電路相比較，成爲可將太陽電池402作 化。

Description of the Invention: [Technical Field] The present invention relates to a non-prior art. By loading a solar cell, a force supply to a device loaded with a solar cell domain is disclosed. In addition, as a solar cell power supply, the technology is reduced, and the following are disclosed. In the patent document 1 (the lithium-ion battery belt provided in Japan, the function of supplying the power source to the gas meter after the sunset is not available from the solar cell, and the solar cell in the patent document 1 is used. Both sides of the pool are provided with an electric conversion unit detected by an electric voltage detecting circuit. Patent Document 2 (a radio remote control device that converts a power source from a solar cell when a solar cell and a dry battery are formed in Japan. The electric remote control. The technology of converting the solar energy into electric energy and the electric device is directed to the load of many primary batteries that are built from the sunlight generated by sunlight during the day. 0 0 0 - 2 2 0 7 9 8), reveals that with the solar cell, during the daytime, the solar cell supplies power to the gas meter, the time zone for photovoltaic power generation, and the lithium-ion gas shut-off control device from the inside. In order to realize the body occlusion control device, the solar voltage detecting circuit is disclosed, and the power supply Kaiping 7-240968 for converting the power source supplied from the pressure gauge to the gas meter is provided. The publication discloses a power supply, and has a power supply line switching hand that requires communication of a large current to a dry battery. Patent Document 2 discloses that a source voltage detecting means is provided, and when detecting a voltage of a solar cell of -5 - 201110505 is detected, 'The radio remote control that converts the power from the solar cell to the dry battery. Patent Document 3 (JP-A-2003-47238) discloses that after the battery reaches the rated discharge end voltage, the voltage is boosted by using a step-up and step-down frequency converter, and the power is supplied to the load, thereby realizing the long life of the battery. Battery-operated electronic devices and mobile communication devices. [Patent Document 1] Japanese Laid-Open Patent Publication No. Hei. No. 2000-220968. Patent Document 2: Japanese Patent Laid-Open Publication No. Hei. No. Hei. The rise in consciousness, the remote control is also required to load a function that extends battery life, a safe and clean source of electricity. The method of extending the battery life of the lithium battery by using the solar battery disclosed in Patent Document 1 and the built-in lithium battery ’ is also an effective means for the remote controller. However, in the method disclosed in Patent Document 1, since the voltage detecting circuit is provided in both the solar cell and the lithium battery, the voltage detecting circuit slightly consumes the constant power. Further, in the manner disclosed in Patent Document 1, a sufficiently large solar cell is mounted, and in the daytime, the time zone is bright, and all the electric power can be supplied from the solar cell, but the remote control considers the convenience of the customer, and there is a period of time. There is a limit on the area on which a small machine can be loaded with solar cells. Therefore, it is impossible to maintain a sufficiently large area of the large current necessary for maintaining the communication of the remote controller. The -6 - 201110505 anode battery cannot be mounted on the remote controller. Patent Document 2 is a subsidy for a dry battery by a solar battery, and has a power supply line switching means for switching a power source from a solar battery to a dry battery when communication requiring a large current is required, and prolonging the life of the dry battery, but it is necessary to convert the power supply line. The circuit and the circuit that detects the power supply voltage make the overall circuit configuration a complicated shortcoming problem. Further, the problem that the circuit for detecting the power supply voltage generates excessive power consumption is the same as that of Patent Document 1. The amount of power generated by the solar cell is increased in proportion to the illuminance. Therefore, under the condition of high illuminance, it is easy to imagine that the output voltage of the solar cell exceeds the terminal voltage of the dry cell. If the output voltage of the solar cell exceeds the terminal voltage of the dry battery, and the circuit used to convert the power supply line is configured as an electronic switch [for example, a switching circuit using an FET (Field Effect Transistor)], a charging current is supplied from the sun by a leakage current. The battery flows to the dry battery. Dry batteries vary depending on the type, but only a small amount of charging current is allowed. In particular, all charging currents are not allowed for alkaline dry batteries or manganese dry batteries. The charging current flows into the dry battery, which is a possibility of inducing a leaking liquid of the dry battery and contaminating the remote controller. Further, leakage current can be prevented by using a circuit configuration for switching the power supply line as a mechanical switch. However, when a power supply line is switched, a state in which power is not supplied from any of the batteries occurs, and an error occurs in the remote controller due to instantaneous power reduction, or a mechanical switch occurs whenever the power is transmitted. The problem of the reduced life of the remote controller of the durability of the mechanical switch used for the conversion, or the limitation of the miniaturization of the switching element, etc. 201110505. Patent Document 3 is that as the portable device is miniaturized, the use of a battery having a high energy density is expanded, but a battery having a high energy density has a large voltage change rate compared with a lithium battery, and a buck-boost converter is used. A person who stabilizes the voltage (constant voltage). As shown in the patent document 3, in order to improve the stability of the circuit of the portable device, it is effective to consider the method of performing constant voltage. Further, after the end voltage of the battery is reached, the step-up and step-down frequency converter is used to boost the voltage, and the way to extend the life of the battery is to achieve high effects and long life of the battery. However, it is effective on a machine used for a single battery, but as in the present invention, a combination of a solar cell and a battery other than a solar cell is used. When other batteries are stepped down, there is a charging current flow by leakage. The other currents cause the same problems as those of Patent Document 2 described above. Thus, the present invention has been made in an effort to provide a remote controller capable of achieving stable usability and long life. The present invention is directed to a remote controller for solving the above problems, and the invention relates to a remote controller for supplying power to a load using a solar battery and another battery, and is characterized in that the solar battery and the other The junction of the battery uses a diode "or circuit, and the solar cell and the other batteries described above supply power from the higher voltage to the above load. According to the present invention, stable use can be provided, and long [Embodiment] The embodiment (hereinafter referred to as "the embodiment") used for carrying out the present invention will be described in detail with reference to the drawings as appropriate. <Overall Configuration of Air Conditioner> First, the overall configuration of the air conditioner 1 that is operated by the remote controller 4 of the present embodiment will be described with reference to Fig. 1 .

The indoor unit transmission/reception unit 231 is configured to receive the infrared signal transmitted from the remote controller 4, and to operate the air conditioner 1 by the infrared signal transmitted from the remote controller 4. Further, the indoor unit transmitting and receiving unit 23 1 can transmit the infrared signal to the remote controller 4. The indoor unit display device 23 2 is an operation state in which the air conditioner 1 is displayed. <Configuration of remote controller> -10- 201110505 Hereinafter, the configuration of the remote controller 4 of the present embodiment will be described with reference to Figs. 2 to 7 . Fig. 2 is a front elevational view showing the remote controller of the embodiment.

Further, the remote control transmitting and receiving unit 401 is formed with indoor air. The thermistor ventilation path 4 that is ventilated to the inside of the remote control transmission/reception unit 401. Fig. 3 is a plan view of the remote controller of the present embodiment. Further, the thermistor ventilation path 4 of the transmitting and receiving unit 401 of the transmission remote controller is removed. The remote control transmitting/receiving unit 40 1 is provided with a light transmitting diode 424 that transmits an infrared signal to the indoor unit transmitting/receiving unit 231 (see FIG. 1 ) of the indoor unit 2 . And an infrared receiver 4 2 5 that receives an infrared signal from the indoor unit transmitting and receiving unit 231 of the indoor unit 2, and detects a temperature of the air around the remote controller 4 via the thermistor ventilation path 410. 4 is a rear view of the remote controller of the present embodiment, and FIG. 5 is a rear view of the exterior of the remote controller of the present embodiment in which the dry battery socket cover is removed. As shown in Fig. 4, 'the detachable -11 - 201110505 dry battery socket cover 4 1 1 is installed on the back of the remote control 4. Also, as shown in Fig. 5, it has: when the dry battery is removed The socket cover 411 converts the battery changeover switch 421 supplied to the remote controller 4, and the dry battery socket 422 for supplying a dry battery (not shown) for supplying power to the remote controller 4, and a battery electrically connected to the dry battery.

Take out the structure. Again, the dry electricity in the remote control 4 The pool socket 422 is enclosed with the attention sign 428 described below. <Circuit Configuration of Remote Control> The circuit configuration of the remote controller 4 of the present embodiment will be described below with reference to Figs. 8 and 9 . Fig. 8 is a circuit diagram of a remote controller of a solar battery which does not have a comparative example. The circuit of the remote controller of the comparative example shown in Fig. 8 includes a dry battery 432 as a power source, a microcomputer 440, a transmission circuit 441, an LCD 403, and an operation button 404. The dry battery 43 2 supplies the power to the transmitting circuit 441 and the microcomputer-12-201110505 440, and also supplies the power to the east microcomputer 440 via the microcomputer 44. The power is transmitted as an electrical signal by the operation command of the operation button 4〇4. The signal sent to the machine 2 is sent from the transmission circuit 441 to the infrared signal. At the same time, the instructions of the microcomputer LCD 403 are operated. Further, the microcomputer 440 is configured to generate a signal from the periphery of the remote controller 4 detected by the remote controller 42 (see FIG. 3) to the indoor unit 2 of the air conditioner 1, and to generate an infrared signal from the LED 424. Here, the problem of the shortcoming of installing the solar cell at the time of comparison can be further explained. The amount of power generated by the solar cell is increased in proportion to the illuminance, and it is conceivable that the solar cell is dried at the terminal voltage of the battery under conditions of high illuminance. When the terminal voltage of the output of the solar cell, the charging current will reduce the safety of the dry battery from the flow of the solar cell, or induce the leakage of the dry battery. Fig. 9 is a circuit diagram of a remote controller according to the present embodiment. The circuit of the remote controller 4 of the present embodiment includes: 451, a bypass booster circuit 452, and a circuit (see Fig. 8). The diode and the regulator 456, and the charging capacitor 457, and { change the dry battery 43 2 (see Fig. 8) to the lithium primary stomach > LCD 403. The indoor pole body 424 of the air conditioner 1 of the air conditioner 1 (see, the 440th is the delivery of the air temperature transmission circuit 441 of the room temperature thermistor. The remote controller circuit of the example is added, and thus the pool is provided. The output voltage overvoltage exceeds the dry battery to the dry battery, and the liquid has a fouled remote control mode diagram. The remote control of the comparative example is a counter-current diode I" or "circuit 4 5 5, C-yang battery 402, and I pool 43 1. The -13- 201110505 <Diode" or "circuit>diode" or "circuit 45 5 is a way in which the cathode side of the diode 45 5a is connected to the cathode side of the diode 455b, by relative arrangement A circuit composed of two diodes 45 5a, 455b. That is, the diode "OR" circuit 45 5 is a circuit for the voltage on the anode side of the diode 45 5 a and the voltage on the anode side of the diode 45 5b, and the current flows from the high side of the voltage. Further, the anode side of the diode 45 5 a is connected to a power supply circuit that supplies a lithium primary battery 43 1 to be described later as a supply source. On the other hand, the anode side of the diode 45 5b is connected to a power supply circuit that uses a solar battery 402 to be described later as a supply source. Further, the cathode side of the diodes 45 5 a, 45 5b is connected to the microcomputer 440 as a load. Thereby, the power source is supplied to the microcomputer 440 from the power supply circuit selected by the diode "or" circuit 45 5 . <Power Supply Circuit Using Solar Cell as Supply Source> First, a power source for supplying the solar battery 402 on the anode side of the diode 45 5b of the diode " or " circuit 455 as a supply source The supply circuit is described. The output voltage of the solar cell 402 is changed by the illuminance. Generally, the remote controller 4 designs the solar battery 4 02 on the premise that the indoor illumination is used, and thus, when it is exposed to intense light such as sunlight, the output voltage of the solar battery 40 2 rises, and the high voltage is increased. Destroy the microcomputer 44 0 or circuit components. In the power supply circuit using the solar battery 402 as a supply source, the regulator 456 is disposed between the solar battery 402 and the anode side of the diode 45 5b, and the upper limit of the voltage supplied to the microcomputer 440 or the like is limited. And the circuit structure to ensure safety. In addition, the limit voltage of the regulator 456 is a number 値 (that is, 2.8 V) that prevents a voltage drop (for example, 0.4 V) of the countercurrent diode 451 from a terminal voltage (about 3.2 V) of the lithium primary battery 431 to be described later. It is also large and is designed not to damage the voltage 微 (for example, 3.0 V) of the microcomputer 440 or the like. Further, the solar battery 402 is a charging capacitor 457 including an electric double layer capacitor to which electric power of the solar battery 402 can be stored. The power supply circuit including the charging capacitor 457 and the solar battery 402 as a supply source is generated when the indoor illumination is turned off by turning on or off the curtain or the indoor lamp, or when the remote controller 4 is tilted. The variation of the output voltage of the solar cell 402 due to the change in intensity can also improve the stability of the power supply. Further, in a state where the current supplied to the load is small, even if the output voltage of the solar battery 402 is small, the electric power stored in the charging capacitor 45 7 can be supplied to the load at a certain timing ′. <Power supply circuit using a lithium primary battery as a supply source> Hereinafter, a lithium primary battery 431 connected to the anode side of the diode 455a of the diode " or " circuit 455 is used as a supply source The power supply circuit is described. When the diode "OR" circuit 45 5 is configured as a circuit connected to the solar cell 402, and the capacitor is connected to the capacitor 45 7 , the following disadvantages must be solved. That is, when there is sufficient illuminance, the voltage of the solar battery 402 and the charging capacitor 457 becomes higher than that of the lithium primary battery 431, and the voltage on the cathode side of the diode 455a becomes higher than the voltage on the anode side of the diode 455a. . Therefore, a leakage current occurs in the diode 45 5a, and the leakage current flows as a charging current of the lithium primary battery 431. The lithium primary battery 431 allows a small amount of charging current, but there is a limit on the allowable charging current, and the charging current must be minimized. Usually, in order to prevent reverse current, a low leakage current preventing reverse current diode 45 1 is inserted and used for the circuit. However, the low leakage leakage preventing reverse current diode 451 has a large voltage drop, and thus the supply voltage from the lithium primary battery 433 is lowered. In other words, the terminal voltage of the lithium primary battery 431 is about 3.2 V. In this case, by preventing the countercurrent diode 45, for example, a voltage drop of about 0.4 V occurs, the supply voltage from the lithium primary battery 431 becomes About 2.8V. When the driving voltage of the microcomputer 440 is 2.5 V, the microcomputer 440 is normally driven even when the anti-current diode 45 1 is inserted. However, when the terminal voltage of the lithium primary battery 43 1 is lowered to 2.8 V, the supply voltage from the lithium-secondary battery 431 is about 2.4 V and the microcomputer 440 cannot be started normally. Thus, even if the terminal voltage of the lithium primary battery 43 1 is higher than the driving voltage of the microcomputer 440, the lithium primary battery 43 1 cannot supply the power to the microcomputer 440 by preventing the voltage drop of the countercurrent diode 451. In other words, the effective use period of the lithium primary battery 43 1 can be significantly reduced. Further, since the transmission circuit 44 1 has a large current of about 500 mA at the time of transmission, the terminal voltage of the lithium primary battery 43 1 is lowered instantaneously when a large current flows. As a result, the supply voltage is instantaneously lowered to the microcomputer 440, and the display of the LCD 4〇3 in which the microcomputer 440 is reset is instantaneously thinned, which is inconvenient. Therefore, the remote controller 4 of the present embodiment can be solved by inserting the power supply circuit having the lithium primary battery 431 as a supply source into the boosting circuit 45 3 (the boosting circuit 452 having the bypass). The bypass booster circuit 452 is a circuit including a bypass diode 454 disposed in parallel with the booster circuit 453. Further, the output voltage of the boosting circuit 453 is a voltage that ensures the driving voltage of the microcomputer 440 (for example, 2.5 V), and is set to be lower than the limiting voltage of the regulator 456 (for example, 3.0 V) (for example, 2.6 V). The bypass booster circuit 452 is in a state where the input voltage exceeds the output voltage of the booster circuit 453 (for example, in the initial state of the lithium primary battery, the terminal voltage of the lithium primary battery is 3.2 V, and the input voltage becomes 2.8. In the state of V, the power supply can be supplied via the bypass diode 454 arranged in parallel, so that the boosting circuit 45 3 is stopped, and the power consumption in the boosting circuit 453 can be reduced. In general, the lithium primary battery 43 1 having a characteristic that the output voltage does not fall to about 80% of the current capacity is more effective, and about 80% of the use period does not require the boosting circuit 453 to be operated. be usable. In the aspect, the bypass booster circuit 452 is in a state where the input voltage is lower than the output voltage of the booster circuit 453 (for example, the lithium primary battery -17-201110505 terminal voltage is lowered to 2.8V, and the input is When the voltage is in the state of 2.4 V, the boosting circuit 45 3 is boosted to secure the driving voltage of the microcomputer 440. Thereby, the power supply circuit using the lithium primary battery 43 1 as a supply source can improve the stability and reliability of the power supply. Further, the lithium primary battery 43 1 is lowered in voltage by the discharge, and even when it is lower than the driving voltage of the microcomputer, the boosting circuit 45 3 is boosted to secure the driving voltage of the microcomputer 44 0 . . Thereby, the use of the lithium primary battery 431 can be extended as much as possible, and the life can be extended. In this way, the bypass booster circuit 452 is provided with the bypass diode 454 in parallel, thereby reducing the voltage of the booster circuit 453 for improving stability and reliability. The power consumption of the circuit 453 can achieve a long life of the lithium primary battery 433. Further, in the booster circuit 453, the frequency fluctuation type boosting method is used. When the boost rate is low, the frequency is reduced to reduce the power consumption of the booster circuit 453. The boost circuit of the mode can further suppress power consumption. As described above, by providing the bypass diode 454 in parallel with the frequency fluctuation type boosting circuit 453, the stability of the circuit can be always ensured, but most of the use period of the remote controller does not use the boosting power. The reason for the road 454 is that the stable operation of the remote controller and the long life of the battery can be achieved at the same time. (Transmission Circuit) The transmission circuit 441 is a load that requires a large current instantaneously at the time of transmission. -18- 201110505 However, the solar battery 402 is disposed on the surface of the remote controller 4 (refer to FIG. 2), but the remote controller 4 is expected to be small in consideration of the user's convenience, and on the front side of the remote controller 4 The operation button 404 and the LCD 403 are disposed. Therefore, the area of the configurable solar cell 402 is limited, and the amount of current supplied by the power supply circuit using the solar cell 420 as a supply source is limited. Therefore, as shown in Fig. 9, the power supply circuit using the solar battery 402 as a supply source is a power supply for the microcomputer 440 or the LCD 403 which does not require a large current, and the transmission circuit 441 which instantaneously requires a large current is made once from the lithium. The configuration in which the battery 43 1 directly receives the power supply is preferable. Thereby, the stability of the power supply to the load of the remote controller 4 can be enhanced. Further, the remote controller 4 is in a transmission state in which the operation button 404 is operated to transmit a large amount of current for transmitting an infrared signal, and a standby state in which only the microcomputer 44A or the LCD 403 is driven without requiring a large current. Here, the remote controller 4 is not an operator frequently, and the period of the standby state is longer than the period of the transmission state. In this manner, the remote controller 4 is designed such that the solar battery 402 can maintain the power in the standby state. Thereby, when the indoor illuminance is sufficient for power generation, the power supply in the standby state is supplied from the power supply circuit using the solar battery 402 as a supply source, and the power consumption of the lithium primary battery 43 1 can be suppressed, and the remote controller 4 can be realized. Long life. Further, if the operation of the operation button 407 is turned off after a predetermined period of time -19-201110505, the LCD 403 can achieve power saving and long life. <Power Supply to Microcomputer> The power supply for each state of the remote controller 4 is first said to be in a standby state for the remote controller 4, and the illuminance of the solar battery 402 of the remote controller 4 is the power for maintaining the standby state. Sufficient (for example, 200 m candle) is explained. At this time, the voltage (3.0 V) supplied from the power supply using the solar battery 402 as a supply source is higher than the voltage (2.6 V to 2.8 V) supplied from the power supply circuit supplied with the lithium primary battery 43 1 . . Therefore, the power supply circuit from the solar battery as the supply source is supplied to the microcomputer 440 by the diode "or circuit 455. Hereinafter, the remote controller 4 is still in the standby state, and the remote controller is in the solar battery. In this case, the voltage generated by the solar battery 402 is lowered, and the voltage stored in the charging capacitor 45 7 is from the voltage of the power supply circuit using the solar battery as a supply source. For a certain period of time, the voltage supplied by the power supply circuit of the lithium primary battery 4 3 1 as the supply source (2.6V to 2.8V) is still high. Therefore, by the diode "or" circuit 4 5 5 The power supply circuit of the solar battery as a supply source is supplied to the microcomputer 440 by the power supply. Thereafter, by continuously supplying the current from the charging capacitor 45 7 to the computer 440, the voltage of the charging capacitor 45 7 is reduced. That is, the positive battery 4 0 2 The voltage supplied by the power supply circuit as the supply source should be sourced for the situation. The circuit is only 402. The ratio of the power to the 402 is reduced to -20-201110505. The voltage supplied from the solar battery 402 as a supply source is smaller than the voltage supplied from the lithium primary battery 43 1 as a supply source, and the diode " or " The battery 43 1 serves as a power supply circuit for supplying power to the brain 44 0. Thus, the electric circuit that converts the solar battery 402 as a supply source and the power supply that supplies the lithium primary battery 43 1 as a supply source are supplied by the diode " Or the circuit 45 5 does not need to have a voltage detection circuit for monitoring each of them, and the circuit can be simplified. Moreover, the voltage detection circuit consumes power even when it is not selected as a circuit that loads the power supply, so The remote controller 4 of the present embodiment having the voltage detecting circuit for lithium primary power can realize the lithium primary battery 43 1 compared with the circuit having the detecting circuit. Therefore, it is not necessary to provide the voltage detection of the solar battery 402. The power consumption can be suppressed in the standby state, whereby the solar battery 402 can be made in comparison with the circuit having the detection circuit. In the case of the circuit, there is no large variation in the voltage supplied to the microcomputer. Moreover, the current is not supplied from the power supply circuit in the switching transmission state and the standby state, and thus the actions of the microcomputer 440 and the LCD 403 are not performed. Therefore, the stable usability of the remote controller 4 can be achieved. The supplied circuit, the lithium-to-micro power supply path is a backup voltage of the long-lived circuit supplied by the voltage of the tank 43 1 by the voltage into a small 440 State, when the state is unstable-21 - 201110505 <Modification of Remote Control Circuit> Hereinafter, a modification of the embodiment will be described. Fig. 10 is a circuit diagram showing a state in which the battery transfer switch is connected to the lithium primary battery and the solar battery in the remote controller according to the modification of the embodiment. Fig. 1 is a circuit diagram showing a state in which a battery changeover switch is connected to a dry battery for a remote controller according to a modification of the embodiment. In addition to the remote controller circuit (see Fig. 9), a modification of the embodiment includes a battery changeover switch 42 1 and a supplementary dry battery 462. The battery changeover switch 42 1 is a switch that switches the two-contact switch of the two circuits and is disposed inside the remote controller 4 covered by the dry battery socket cover 41 (refer to Fig. 4, Fig. 5). Further, the battery changeover switch 42 1 does not switch between the communication state and the standby state, but is operated by the operator when the auxiliary dry battery 462 is inserted after the end of the lithium primary battery 43 1 is used. The auxiliary dry battery 462 is an alkaline dry battery or a manganese dry battery inserted into the dry battery socket 422, and is connected to the circuit via the battery connection terminal 42 3 . Also, these are dry batteries for general-purpose products that are also available in hypermarkets. When the solar battery 402 and the lithium primary battery 43 1 are used, when the power is supplied to the remote controller 4, as shown in FIG. 10, the battery changeover switch 421 is connected to the solar battery 402, the regulator 456, and the charging capacitor 457. The lithium primary battery 43 1 is connected to the anode side of the countercurrent diode 45 1 to perform a changeover switch. This is equivalent to the circuit diagram shown in Fig. 9 -22-201110505, and thus the description thereof is omitted. On the other hand, the case where the lithium primary battery 431 is discharged and the remote controller 4 is in an unusable state will be described. As shown in FIG. 1, the user switches the battery changeover switch 42 1 into the solar cell 402, the regulator 45 6 and the charging capacitor 457, and prevents the anode side of the countercurrent diode 451 from being once from the lithium. The battery 431 is connected to the auxiliary dry battery 462. In the remote controller circuit of the comparative example shown in Fig. 8, the anti-current diode 451 is assembled, and the step-up booster circuit 452 and the diode 455a are approximately equal. According to this configuration, the microcomputer 440 is supplied with power from the supplementary dry battery 462 via the booster circuit 452. Further, a power supply is directly supplied from the auxiliary dry battery 462 to the transmission circuit 441 which requires a large current. By the use of the commercially available alkaline dry battery or the manganese dry battery as the auxiliary dry battery 462 after the discharge of the lithium primary battery 433, the remote controller 4 can be used. Further, the auxiliary dry battery 46 2 is electrically disconnected from the lithium primary battery 43 1. The solar battery 402 is electrically disconnected, and no charging current flows to the auxiliary dry battery 462 by leakage. Thereby, leakage from the auxiliary dry battery 462 can be prevented. Further, the circuit is switched so that only one battery changeover switch 42 1 can be operated, and by the user's setting error 'operation error, the charge current flows in the auxiliary dry battery 462 to prevent liquid leakage. Further, when the battery changeover switch 421 is switched, there is no power supply from the lithium primary power -23-201110505 pool 43 1 and the auxiliary dry battery 462 to the microcomputer 440, but the power is supplied to the microcomputer 440 by the charging capacitor 457. Therefore, there is no case where the setting of the microcomputer 44 0 is reset. Further, the charging current flows from the charging capacitor 45 7 to the auxiliary dry battery 462, and the reverse current capacitor 451 is prevented from being prevented. At the same time, the auxiliary dry battery 462 starts to lower the voltage earlier than the lithium primary battery 431, but is boosted by the booster circuit 453, so that the operation of the microcomputer 440 or the LCD 403 is not unstable. In addition, it is possible to extend the life of the auxiliary dry battery 462. When the auxiliary dry battery 462 has a sufficient voltage, current flows through the bypass diode 454, and the power consumption of the booster circuit 453 is suppressed to be the same as in the case of the lithium primary battery. Further, at the time of transmission, a large current is required by the transmission circuit 441, and even if the terminal voltage of the auxiliary dry battery 462 is lowered, the voltage is boosted by the booster circuit 453, so that the operation of the microcomputer 44 or the LCD 403 does not occur. Unstable situation. Thereby, the stable usability of the remote controller 4 can be obtained, the life of the auxiliary dry battery 462 can be extended, and the power of the remote controller circuit can be saved. Further, when the solar battery 402 and the lithium primary battery 431 are used, when the remote controller 4 supplies power, it is not necessary to insert the auxiliary dry battery 462. Further, the lithium primary battery has a long life compared with the manganese dry battery or the alkaline dry battery, and the remote controller circuit of the embodiment has the solar battery 402 and the like, and can have a longer life. Therefore, in the empty dry battery socket 422, when the remote controller 4 (including the air conditioner 1 of the remote control-24-201110505 4) is shipped, the operation for the battery changeover switch 421 and the insertion of the auxiliary dry battery 462 are enclosed. Note that the brand 428 (refer to Figure 7) is also available. Thereby, when the lithium primary battery 43 1 or the solar battery 402 supplies electric power to the remote controller circuit, the dry battery which is not originally required is inserted into the dry battery socket 4 22, and the dry battery is consumed by natural discharge without using the electric power in the dry battery. It can prevent waste that becomes unusable. <Others> The remote controller 4 of the present embodiment is incorporated in the air conditioner 1, but the present invention is not limited thereto, and may be used in, for example, an AV (Audio, Visual) machine. Remote control. Further, a lithium primary battery is exemplified as another battery connected in parallel with the solar battery 402 via the diode " or " circuit 455, but of course, the same can be obtained by using another primary battery that can tolerate leakage. The effect can be appropriately selected. BRIEF DESCRIPTION OF THE DRAWINGS Fig. 1 is a configuration diagram of an air conditioner including a remote controller according to the present embodiment.
