201109595 六、發明說明 【發明所屬之技術領域】 本發明，係有關於具備有遙控器之位置檢測功能的空 調機。 【先前技術】 空調機，係成爲將室內機與室外機經由連接配管來相 連結的構成。在室內，使用者係使用獨立的遙控控制器 (以下，稱爲遙控器）來對於空調機之功能進行操作。 空調機，係將室內之空氣取入至室內機的熱交換器 中’並藉由加熱、冷卻、除濕等之功能來作調整，而將此 調整後之空氣吹出至室內，藉由此，來對於室內作空調。 此時，室內溫度之控制，係根據使用者藉由遙控器所設定 了的設定溫度、和藉由被設置在室內機本體處之吸入溫度 熱阻器所檢測出的吸入空氣溫度，而進行之。 但是，由於通常空調機之室內機係被安置在室內之高 處，因此，係並不一定會成爲與使用者之居住空間相同的 溫度，而會產生有溫度差。又，依存於例如在室內機之前 方被放置有障礙物的情況等之室內環境，會產生被作了空 調後之吹出口的空氣滞留在室內機附近而無法在室內全體 作循環之所謂的短路現象，而會有在與使用者所居住的空 間之溫度間出現大的溫度差之情況。 又，當使用者位在射入有陽光之窗邊或是使用有瓦斯 爐之廚房等的局部性溫差爲大之空間的情況時，亦會有與 -5- 201109595 所吸入之空氣溫度之間產生大的溫度差之情況。 相對於此，在先前技術之空調機中，係提案有下述之 控制方法：在對於空調機進行操作之遙控器處搭載將室溫 檢測出來之室溫熱阻器，而將在使用者之任意位置處的室 溫檢測出來。而後，從遙控器而將所檢測出之室溫對於空 調機作送訊，並且，藉由遙控器位置檢測手段來辨識出使 用者之任意的位置，而對於該處與吸入口之空氣溫度之間 的溫度差作修正。 又，作爲用以檢測出室溫之手段，由於隨著室溫而使 電阻値改變之溫度熱阻器係爲低價，且能夠得到充分之檢 測精確度，因此，係多所被使用，但是，作爲遙控器之位 置檢測手段，係提案有各種之方法。 作爲檢測出遙控器位置的先前技術，專利文獻1〜4 係爲週知。 專利文獻1中，係揭示有一種空調用遙控器之技術， 其係具備有遙控器控制手段，該遙控器控制手段，係具備 有：在遙控器與空調機之間而進行雙方向通訊的遙控器通 訊手段、和對於時間作計測之時間計測手段，其特徵爲： 根據藉由時間計測手段所計測出之從指令之送訊起直到處 理結果之受訊爲止的經過時間，來計算出與空調機之間的 距離，並根據距離來進行空調控制。 專利文獻1，係爲將紅外線作爲通訊媒體而對空調機 本體與遙控器作雙方向通訊者’並藉由對於在雙方向通訊 時之送受訊間的時間作測定’來測定出距離°由於紅外線 -6 - 201109595 訊號之通訊速度係爲光速，因此，紅外線訊號前進lm所 需要之時間’係僅需要約3 .3 η秒。故而，爲了檢測出室 內空間中的距離’係最少需要數百Ρ秒之解析度，但是， 一般而言，在家庭電器製品中所被使用的泛用微電腦之計 時器的精確度，最多也僅爲數//秒，因此，係需要非常高 精確度之計時器’若是對成本面作考量，則並不現實》 又，當想定爲實際使用在家庭電器製品中的情況時， 亦有必要對於雜訊所導致之誤檢測作考慮，但是，爲了檢 測出數百Ρ秒的時間差，係並無法附加雜訊截除用之濾波 電路，而成爲無法期待S/N比之提升，並發生無法以高精 確度來進行檢測之問題。 專利文獻2中，係揭示有一種環境調整系統，該環境 調整系統，係具備有：作出在密閉空間中之環境條件的環 境設備、和對於此環境設備而藉由無線電波來賦予密閉空 間之環境條件指令的附有感測器之遙控器，並且，係由環 境設備或是附有感測器之遙控器所受訊的訊號之強度或者 是傳輸延遲時間，而求取出距離》 專利文獻2，係爲將無線電波作爲通訊媒體而對環境 設備與遙控器作雙方向通訊者，並由受訊時之訊號強度或 是傳輸延遲時間而求取出距離。爲了檢測出遙控器之方 向，係需要設置複數之成爲受訊部的天線，而在成本上殘 留有課題。又，爲了從傳輸延遲時間而求取出距離，係與 專利文獻1之紅外線方式相同的，由於電波亦爲非常高 速，因此，在演算處理上係殘留有課題。又，由於電波係 201109595 爲法律規制之對象，因此，相對於製品之規格，並無法對 於訊號強度自由地作設定，而在泛用性上亦殘留有課題。 專利文獻3，係揭示有一種關於位置檢測系統及位置 檢測方法以及紅外線遙控器受訊機之技術，其中，係具備 有受光紅外線訊號之2個以上的受光手段，各受光手段， 係具備有將複數之受光單元配列在MxN個之2維矩陣上 所構成的受光面，並在因應於受光強度而輸出檢測訊號的 同時，對於在受光面上之紅外線訊號的受光位置作特定。 而位置檢測手段，係由受光位置而根據三角測量之原理等 來計算出遙控器送訊機之相對位置。藉由此，而檢測出紅 外線遙控器之送訊機與受訊機間的相對性位置關係。 在專利文獻3中，由於係藉由三角測量之原理來演算 出遙控器位置，因此，係必須要在室內機側處設置一對之 具備有將紅外線光源之像在2維矩陣之受光單元上作結像 的精確度爲高之光學系的受光部，而會耗費非常大的成 本，並且，將此作收容之室內機的尺寸亦不得不增大，在 成本競爭力爲重要的家庭電器製品中，係終究無法作使 用。 在專利文獻4中，係揭示有一種電性機器之技術’該 電性機器，係由電性機器本體和遙控器所構成，該電性機 器本體，係具備有進行對於遙控器之訊號送訊的訊號送訊 手段、和進行從遙控器而來之訊號之受訊的訊號受訊手 段、和使用者可直接進行操作的輸入手段、和將由輸入手 段所致之遙控器位置檢測訊號作送訊的手段’而該遙控 -8- 201109595 器，係具備有：進行從電性機器本體而來之訊號之受訊的 訊號受訊手段、和進行對於電性機器本體之訊號送訊的訊 號送訊手段、和當受訊了遙控器位置檢測訊號時，直接將 遙控器位置檢測確認訊號送訊至電性機器本體處的送訊手 段，電性機器本體，係在送訊了遙控器位置檢測訊號後， 對於直到受訊了遙控器位置檢測確認訊號爲止所經過的時 間作計測，並根據計測時間而演算出電性機器本體與遙控 器間之距離，再將演算出之距離訊號作送訊，而遙控器， 係根據所受訊了的距離訊號，而輸出警報。 專利文獻4，係與專利文獻1相同的，爲對於電性機 器本體與遙控器作雙方向通訊者，並藉由對於在雙方向通 訊時之送受訊間的時間作測定，來測定出距離。因此，係 與專利文獻1相同的，在精確度或是成本面上殘留有大的 課題。 [先前技術文獻] [專利文獻] [專利文獻1]日本特開2008-309379號公報 [專利文獻2]日本特開2007-127348號公報 [專利文獻3]日本特開2001-197577號公報 [專利文獻4]日本特開2004-304408號公報 【發明內容】 [發明所欲解決之課題] 在先前技術中’係存在著：依存於空調機所在之空調 -9 - 201109595 空間的環境條件，而在設定溫度與使用者所在之周圍空間 溫度之間產生大的溫度差之問題。舉例而言，係有著如同 前述一般之在窗邊或是蔚房之類的局部性溫度差爲大之環 境、或者是發生有空調後所吹出的空氣在室內機附近滯留 而並未在室內全體作循環之所謂的短路現象一般之環境。 因此，爲了解決此問題，係提案有下述之方法：亦即 是，使用如同前述一般之在遙控器處所具備的遙控器位置 檢測手段和溫度熱阻器，來檢測出使用者之任意位置處的 溫度，並藉由將所檢測出之位置資訊和溫度資訊送訊至空 調機處，而對溫度差作修正。 然而，如同上述一般，爲了檢測出遙控器之位置，係 需要專用之遙控器位置檢測裝置，而有著會造成成本上升 或是裝置之複雜化的問題。 本發明，係爲了解決上述之先前技術的課題而進行 者，其目的，係在於提供一種能夠以低成本而檢測出遙控 器之位置的空調機。 [用以解決課題之手段]

內紅外線發光二極體32、33、34。藉由如此這般地來構 成，而謀求系統之簡單化以及成本之降低。 另外，「位置」’係藉由「距離」與「方向」來作表 現。 在圖5中，係藉由切換（SW)電源70、18.5V電源 71、12V 電源 72、8.5V 電源 73、調節器（regul at〇r ) 74、5V電源75，而構成電源部。於此些處，係被供給有 從交流電源51而來之電力。室內機微電腦22，係被連接

內紅外線發光二極體3 3之陰極側係經介於電阻R2而被連 接於載波頻率產生開關元件49之其中一端處，室內紅外 線發光二極體3 4之陰極側係經介於電阻R3而被連接於載 波頻率產生開關元件49之其中一端處。又，載波頻率產 生開關元件49之另外一端，係成爲0V。 詳細雖於後再述，但是，室內紅外線發光二極體 3 2、3 3、3 4，係預先對於分別擔當存在於何一位置（區 域）處之遙控器5的檢測一事作了決定（參考圖3 )。例 如，室內紅外線發光二極體3 2，係爲中區域檢測用，並 -18- 201109595 對於從正面而觀察室內機2時之正面方向（中間區域）送 訊紅外線訊號。又，室內紅外線發光二極體3 3，係爲左 區域檢測用，並對於從正面而觀察室內機2時之左方向 (左區域）送訊紅外線訊號。又，室內紅外線發光二極體 3 4，係爲右區域檢測用，並對於從正面而觀察室內機2時 之右方向（右區域）送訊紅外線訊號。 在此種構成中，參考圖6之流程圖（一倂參考圖 1 1 )，來對於從室內機2而來之位置判別訊號的輸出動作 作說明。 當室內紅外線受光元件18受訊從遙控器5而來之後 述的位置檢測要求訊號，而後室內紅外線受光元件1 8進 行內部處理並變換爲數位訊號而對於室內機微電腦22作 了輸出時（SI : YES )，室內機微電腦22，係因應於所受 訊了的位置檢測要求訊號，而開始遙控器位置檢測控制。 在本實施型態中，爲了實行遙控器位置檢測控制，係 使用3個的室內紅外線發光二極體3 2、3 3、3 4，來檢測 出遙控器5之方向、距離。 首先，將開關元件35、36、37設爲ON，並從室內紅 外線發光二極體32、33、34而將藉由載波頻率產生用之 開關元件49而被調變爲38kHz之載波頻率（DUTY 50% )後的紅外線訊號作送訊（S2

22，係對於DC/DC換流電路38而輸出將輸出電壓設爲可 作複數階段之變化的輸出電壓指令訊號。藉由此，在室內 紅外線發光二極體32中所流動之驅動電流係被變更，而 位置判別訊號之輻射強度，係如同圖1 1中所示一般，從 「強」—「中」—「弱」—「微弱」地而階段性地減弱。 又，在S 4與S 5中亦同樣的，開關元件3 5、3 6、3 7 係被依序作切換，並與步驟S 3同樣的，位置判別訊號之 輻射強度係階段性地減弱。 關於此些之詳細內容，係於後參考圖18等而作說 明。 另外，在本實施型態中，雖係設爲經由DC/DC換流 電路38來將驅動電流設爲可變之構成，但是，經由設置 複數之限制電阻，並對於此限制電阻作切換，亦可得到相 -20- 201109595 同之效果。 〈遙控器側之遙控器位置檢測裝置的構成〉 接著，針對遙控器側之遙控器位置檢測裝置的構

Field of the Invention The present invention relates to an air conditioner including a position detecting function of a remote controller. [Prior Art] The air conditioner is configured to connect the indoor unit and the outdoor unit via a connection pipe. Indoors, the user operates an independent air conditioner (hereinafter referred to as a remote controller) to operate the functions of the air conditioner. The air conditioner takes the air from the room into the heat exchanger of the indoor unit' and adjusts it by heating, cooling, dehumidifying, etc., and blows the adjusted air to the room, thereby For indoor air conditioning. At this time, the control of the indoor temperature is performed according to the set temperature set by the user by the remote controller and the intake air temperature detected by the suction temperature heat resistor provided at the indoor unit body. . However, since the indoor unit of the air conditioner is usually placed at a high level in the room, the temperature is not necessarily the same as the living space of the user, and a temperature difference is generated. In addition, depending on the indoor environment in which an obstacle is placed in front of the indoor unit, for example, a so-called short circuit in which the air that has been blown out by the air conditioner stays in the vicinity of the indoor unit and cannot be circulated indoors is generated. Phenomenon, there will be a large temperature difference between the temperature of the space in which the user lives. In addition, when the user is in a space where a local temperature difference such as a window with a sunlight or a kitchen with a gas burner is used, there is also a temperature between the air temperature and the air temperature inhaled by -5-201109595. A large temperature difference is generated. On the other hand, in the air conditioner of the prior art, there is proposed a control method in which a room temperature heat resistor that detects a room temperature is mounted on a remote controller that operates the air conditioner, and will be used by the user. The room temperature at any position is detected. Then, the detected room temperature is sent from the remote controller to the air conditioner, and the position of the user is recognized by the remote controller position detecting means, and the air temperature of the air inlet and the suction port is recognized. The temperature difference between them is corrected. Further, as means for detecting the room temperature, since the temperature of the resistor is changed to a low temperature with room temperature, and the temperature is low, and sufficient detection accuracy can be obtained, many of them are used, but As a means of detecting the position of the remote controller, various methods have been proposed. As prior art for detecting the position of the remote controller, Patent Documents 1 to 4 are well known. Patent Document 1 discloses a technique of a remote controller for an air conditioner, which is provided with a remote controller control means including a remote control for bidirectional communication between a remote controller and an air conditioner. The means for communicating with the device and the time measuring means for measuring the time are characterized in that: the air conditioner is calculated based on the elapsed time from the transmission of the command to the reception of the processing result by the time measuring means. The distance between the machines and the air conditioning control according to the distance. Patent Document 1 is to measure the distance by using infrared rays as a communication medium to make a two-way communication between the air conditioner main body and the remote controller and to measure the time between transmission and reception in the case of communication in both directions. -6 - 201109595 The communication speed of the signal is the speed of light, so the time required for the infrared signal to advance lm 'only needs about 3 . 3 η seconds. Therefore, in order to detect the distance in the indoor space, it requires a resolution of at least several hundred seconds. However, in general, the accuracy of the timer of the general-purpose microcomputer used in household electrical appliances is at most only In the number of / / sec, therefore, it is necessary to have a very high precision timer. If it is considered for the cost side, it is not realistic. Also, when it is considered to be actually used in household electrical appliances, it is also necessary to In view of the erroneous detection caused by noise, in order to detect the time difference of several hundred secs, it is impossible to add a filter circuit for noise interception, and it is impossible to expect an increase in the S/N ratio, and it is impossible to High accuracy for detection problems. Patent Document 2 discloses an environment adjustment system including an environmental device that makes an environmental condition in a confined space, and an environment in which a confined space is given by radio waves to the environmental device. The remote command of the conditional command is attached to the sensor, and the intensity of the signal received by the environmental device or the remote controller with the sensor is the transmission delay time, and the distance is taken out. Patent Document 2 It is a two-way communication between the environmental equipment and the remote controller by using radio waves as a communication medium, and the distance is obtained by the signal strength or the transmission delay time at the time of receiving the signal. In order to detect the direction of the remote controller, it is necessary to set a plurality of antennas to be the receiving unit, and there is a problem in terms of cost. In addition, in order to obtain the distance from the transmission delay time, the radio wave is also at a very high speed in the same manner as the infrared method of Patent Document 1, and therefore there is a problem in the calculation processing. Moreover, since the electric wave system 201109595 is a subject of legal regulation, it is not possible to freely set the signal strength with respect to the specifications of the product, and there is a problem in the generality. Patent Document 3 discloses a technique for detecting a position detecting system, a position detecting method, and an infrared remote controller, in which two or more light receiving means having a light receiving infrared signal are provided, and each light receiving means is provided. The plurality of light receiving units are arranged on the light receiving surface formed by the MxN two-dimensional matrix, and the detection signal is output in response to the received light intensity, and the light receiving position of the infrared signal on the light receiving surface is specified. The position detecting means calculates the relative position of the remote controller from the light receiving position based on the principle of triangulation. Thereby, the relative positional relationship between the transmitter of the infrared remote controller and the receiver is detected. In Patent Document 3, since the position of the remote controller is calculated by the principle of triangulation, it is necessary to provide a pair of light receiving units having an image of the infrared light source in a two-dimensional matrix on the indoor unit side. The accuracy of the image is high in the light-receiving portion of the optical system, which is very expensive, and the size of the indoor unit to be accommodated has to be increased, and the household electrical appliance is important in cost competitiveness. In the end, the system cannot be used after all. Patent Document 4 discloses a technique of an electric device, which is composed of an electric machine body and a remote controller, and the electric device body is provided with signal transmission for a remote controller. The signal transmission means, the signal receiving means for performing the signal from the remote controller, the input means for the user to directly operate, and the remote position detecting signal by the input means for transmitting The remote control-8-201109595 is equipped with a signal receiving means for transmitting signals from the electrical machine body and a signal transmitting signal for signal transmission to the electrical machine body. The means, and when the remote position detection signal is received, the remote position detection confirmation signal is directly sent to the communication means at the electric machine body, and the electric machine body transmits the remote position detection signal After that, the time elapsed until the remote controller position detection confirmation signal is received is measured, and the distance between the electric machine body and the remote controller is calculated according to the measurement time. Off, the calculated distance signal is sent for transmission, and the remote controller outputs an alarm according to the distance signal received. Patent Document 4 is the same as Patent Document 1, and is a bidirectional communication device for an electric machine main body and a remote controller, and measures the distance between the time of transmission and reception when communicating in both directions. Therefore, in the same manner as in Patent Document 1, there is a large problem remaining on the accuracy or the cost. [Patent Document 1] [Patent Document 1] JP-A-2008-309377 (Patent Document 2) JP-A-2007-127348 (Patent Document 3) JP-A-2001-197577 [Problem to be Solved by the Invention] In the prior art, there is a problem that depends on the environmental conditions of the air conditioner -9 - 201109595 where the air conditioner is located, There is a problem of a large temperature difference between the set temperature and the temperature of the surrounding space where the user is located.

Fig. 5 is a view showing a system configuration of the indoor transmitting and receiving unit 16 that functions as a remote controller position detecting device on the indoor unit 2 side. Fig. 6 is a flow chart for explaining an output operation of a position discrimination signal from the indoor unit 2. First, the remote controller position detecting device on the indoor unit 2 side uses the indoor infrared light receiving element 18 and the indoor infrared ray of the indoor transmitting and receiving unit 16 that constitutes the two-way communication between the indoor unit 2 and the remote controller 5 as described above. Light-emitting diodes 32, 33, 34. By constructing in this way, the system is simplified and the cost is reduced. In addition, "location" is represented by "distance" and "direction". In Figure 5, by switching (SW) power supply 70, 18. 5V power supply 71, 12V power supply 72, 8. The 5V power supply 73, the regulator (regul at〇r) 74, and the 5V power supply 75 constitute a power supply unit. At these places, power from the AC power source 51 is supplied. The indoor unit microcomputer 22 is connected. • 17-201109595 at the 5V power supply 75. The indoor unit microcomputer 22 is connected to the switching elements 35, 36, and 37, and controls the ΟΝ/OFF of each switching element. Further, at the indoor unit microcomputer 22, a carrier frequency generation switching element 49 for generating a carrier frequency is connected, and control is made for the generation of a carrier frequency (DUTY 5 0%) of 38 kHz. Further, the indoor unit microcomputer 22 is connected to the DC/DC converter circuit 38 which receives the 12V power source 72 as an input, and controls the output voltage of the DC/DC converter circuit 38. At the output side of the DC/DC converter circuit 38, the anode side of the indoor infrared light-emitting diode 32 is connected via the switching element 35, and is connected to the room via the switching element 36. The anode side of the infrared light-emitting diode 3 3 is connected to the anode side of the indoor infrared light-emitting diode 34 via the switching element 37. The cathode side of the indoor infrared light-emitting diode 32 is connected to one end of the carrier frequency generating switching element 49 via the resistor R1, and the cathode side of the indoor infrared light-emitting diode 33 is interposed between the resistor R2. Connected to one end of the carrier frequency generating switching element 49, the cathode side of the indoor infrared light emitting diode 34 is connected to one end of the carrier frequency generating switching element 49 via the resistor R3. Further, the other end of the carrier frequency generating switching element 49 is 0V. Although the details will be described later, the indoor infrared light-emitting diodes 3 2, 3 3, and 3 4 are determined in advance for the detection of the remote controller 5 at which position (area) is present (refer to image 3 ). For example, the indoor infrared light-emitting diode 32 is used for mid-range detection, and -18-201109595 transmits an infrared signal to the front direction (middle area) when the indoor unit 2 is viewed from the front. Further, the indoor infrared light-emitting diode 3 3 is used for detecting the left area, and transmits an infrared signal to the left direction (left area) when the indoor unit 2 is viewed from the front. Further, the indoor infrared light-emitting diodes 3 4 are for detecting the right area, and send infrared signals to the right direction (right area) when the indoor unit 2 is viewed from the front. In such a configuration, the output operation of the position discriminating signal from the indoor unit 2 will be described with reference to the flowchart of Fig. 6 (refer to Fig. 1 1). When the indoor infrared light receiving element 18 receives the position detection request signal described later from the remote controller 5, the indoor infrared light receiving element 18 performs internal processing and converts it into a digital signal to output to the indoor unit microcomputer 22 (SI: YES), the indoor unit microcomputer 22 starts the remote position detection control in response to the position detection request signal that has been received. In the present embodiment, in order to implement the remote controller position detection control, three indoor infrared light-emitting diodes 3 2, 3 3, and 3 4 are used to detect the direction and distance of the remote controller 5. First, the switching elements 35, 36, and 37 are turned ON, and the carrier frequency (38 kHz) is converted from the indoor infrared ray-emitting diodes 32, 33, and 34 by the carrier frequency generating switching element 49 (DUTY). After 50%), the infrared signal is sent (S2). In addition, the infrared signal ' is shown in the figure as a basic operation signal. Further, in the basic operation signal, the operation information (intake temperature, humidity, etc.) of the indoor unit 2 is added. -19 to 201109595 Next, the indoor infrared light-emitting diode 32 for detecting the medium region is used to transmit the position discrimination signal (S3) shown in Fig. 11. Then, the indoor infrared light-emitting diode 3 3 for detecting from the left region is transmitted, and the position discrimination signal (S4) shown in Fig. 11 is transmitted. Thereafter, the indoor infrared light-emitting diodes 34 for detecting from the right region are transmitted, and the position discrimination signal (S 5 ) shown in Fig. 11 is transmitted. Further, in step S3, the indoor unit microcomputer 22 turns on the switching elements 35 of the switching elements 35, 36, and 37, and detects the indoor infrared light-emitting diodes 32 for the medium area by the carrier frequency. The infrared signal of the position discriminating signal after the switching element 49 is generated and converted to the carrier frequency of 38 kHz is transmitted. At this time, the indoor unit microcomputer 22 outputs an output voltage command signal for changing the output voltage to a plurality of stages for the DC/DC converter circuit 38. Thereby, the driving current flowing in the indoor infrared light-emitting diode 32 is changed, and the radiation intensity of the position determining signal is as shown in Fig. 11. From "strong" - "medium" - " Weak" - "weak" and gradually weakened. Further, similarly in S4 and S5, the switching elements 35, 3, and 3 are sequentially switched, and the radiation intensity of the position discriminating signal is gradually weakened in the same manner as in step S3. The details of this will be described later with reference to Fig. 18 and the like. Further, in the present embodiment, the drive current is made variable by the DC/DC converter circuit 38. However, by setting a plurality of limiting resistors, the limiting resistor is also switched. The same effect can be obtained with phase -20- 201109595. <Configuration of remote controller position detecting device on the remote controller side> Next, the configuration of the remote controller position detecting device on the remote controller side will be described with reference to Figs. 7 and 8 . Fig. 7 is a view showing the configuration of the remote controller 5. Fig. 8 is a view showing the system configuration of the remote controller 5. Fig. 7(a) shows the display operation of the remote controller 5. As shown in (a) of FIG. 7, the remote controller 5 is composed of an operation surface 48 provided with an operation key 65, an LCD module 50 displayed with an operation information, and two-way communication with the indoor unit 2. The remote controller covered by the cover 40a is configured to be sent to the receiving unit 40. Further, the light cover 40a is provided with a vent hole 40b for a room temperature heat resistor and humidity sensing which will be described later. (b) of Fig. 7 is a display case for the display operation surface of the remote controller 5 and is provided with a back cover 80. (c) of Fig. 7 is a display for the state in which the back cover 80 of the remote controller 5 is unloaded into the battery 44. In other words, the remote controller 5 allows the user to operate the space 1 regardless of the position in the room, and the wireless device with the infrared light-emitting diode has a remote control unit for the remote control. 40 or LCD mode | battery 44 for power supply. (d) of Fig. 7 is a constructor for the remote controller transmitting and receiving unit 40. Fig. 7(d) is a view seen from the direction A in the case of the device 5 shown in Fig. 7(a). The remote controller sends the receiving unit 40, and the other is B. The exhibition is set up to receive the light under the back of the receiver, and is adjusted to the machine, and a 5 〇 into the remote control, Department-21 - 201109595 is equipped with a remote control infrared light-receiving element 4 1, remote control infrared light-emitting diode Body 42. Further, the remote controller transmitting and receiving unit 40 also functions as a remote controller position detecting device on the remote controller side, and the system is simplified and the cost is reduced. Further, a room temperature heat resistor 43a and a humidity sensor 43b that detect the room temperature are mounted next to the remote controller transmitting and receiving unit 40, so that the room temperature and humidity around the remote controller 5 can be detected at any time. . As shown in Fig. 8, generally, the remote controller 5 is provided with a remote controller micro-computer 45. The remote controller microcomputer 45 is connected to a carrier frequency generating switching element 46 for generating a carrier frequency, and controls the generation of a carrier frequency of 38 kHz. Further, the remote controller microcomputer 45 is connected to the switching element 47, and controls the ON/OFF of the switching element 47. The remote control infrared light receiving element 4 1 is connected to the battery 44 via one of the switching elements 47, and the other end is connected to the remote control microcomputer 45. The remote control infrared light receiving element 4 1 is for indoor use. The position discrimination signal sent by the machine 2 is received and output to the remote controller microcomputer 45. Further, the remote control infrared light receiving element 41 is turned OFF by the switching element 47. The remote control infrared light-emitting diode 42 has an anode side connected to the battery 44, and a cathode side connected to one end of the carrier frequency generating switching element 46 via a resistor R4. Further, the other end of the carrier frequency generating switching element 46 is 0V. One end of the room temperature thermistor 43a is connected to the battery 44, and one end of the -22-201109595 is connected to the remote controller microcomputer 45, and the room temperature information signal is output to the remote controller microcomputer 45. The remote controller microcomputer 45 transmits the room temperature information as the temperature of the peripheral space of the remote controller 5 to the indoor transmitting and receiving unit 16 of the indoor unit 2 via the remote controller transmitting and receiving unit 40 based on the room temperature information signal. When the room temperature information of the remote controller 5 is received by the indoor transmitting and receiving unit 16, the indoor unit microcomputer 22 is based on the room temperature information of the remote controller 5 and the suction temperature resistor 23 of the indoor unit 2. The room temperature information is compared and the temperature difference (temperature difference) is appropriately corrected (refer to Figure 4). The humidity sensor 4 3 b is connected to the battery 44 at one end, and the other end is connected to the remote controller microcomputer 45, and outputs the humidity information signal to the remote controller microcomputer 45. The remote controller microcomputer 45 transmits the humidity information as the humidity of the peripheral space of the remote controller 5 to the indoor transmitting and receiving unit 16 of the indoor unit 2 via the remote controller transmitting and receiving unit 40 based on the humidity information signal. When the humidity information of the remote controller 5 is received by the indoor transmitting and receiving unit 16, the indoor unit microcomputer 22 is the humidity information of the remote controller 5 and the humidity information from the humidity sensor 25 of the indoor unit 2. For comparison, the difference in humidity (humidity difference) is appropriately corrected (refer to Fig. 4). In Fig. 8, the remote controller microcomputer 45 recognizes each operation mode by the user pressing a specific operation key 65. When the command signal of the remote controller position detection caused by the operation of the operation key (the position confirmation key (not shown) 65 is input to the remote controller microcomputer 45, the remote controller microcomputer 5 is for detecting the above position. The request signal is sent to the indoor unit 2-23-201109595, and the 载波/OFF of the carrier frequency generating switching element 46 is controlled, and the driving current is flowed at the infrared illuminating diode 42 of the remote controller, and the infrared ray is received by the remote controller. The switching element 47 of the element 41 is set to an ON state for a specific time. The reason why the remote control infrared light receiving element 41 is set to the ON state at a specific time is to receive a signal for determining the position from the indoor unit 2 only for a specific period of time. Normally, the power of the remote control infrared light receiving element 4 1 is turned off (the switching element 47 is turned off), and the standby power is consumed, whereby the battery life of the remote controller 5 is extended and sought. Prevention of malfunctions in an environment where there is strong noise in the radiation. <Detection of distance of remote controller> Next, the detection of the distance between the indoor unit 2 and the remote controller 5 will be described with reference to Figs. 9 to 12 . Figure 9 is a graph showing the relationship between the drive current flowing in the infrared light-emitting diode and the radiation intensity. Figure 1 〇 ' is a diagram showing the relationship between the arrival distance of the infrared signal and the radiation intensity. Fig. U' is a diagram for explaining a position discrimination signal transmitted from the indoor unit 2 side. Fig. 12 is a diagram showing the range of the infrared light receiving element 41 of the remote controller at each radiation intensity of the position discriminating signal. Fig. 13 is a timing chart for explaining the detection operation of the distance between the indoor unit 2 and the remote controller 5. As shown in FIG. 9 , the indoor infrared light-emitting diode (3 2, 3 3, 3 4 ) is provided with a radiation intensity of the radiated red-24 - 201109595 external signal as the driving current increases. Infinitely enhanced characteristics. Moreover, as shown in Fig. 1 一般, the infrared radiation intensity is attenuated as the distance increases in accordance with the law inversely proportional to the square of the distance. Therefore, the radiation intensity is weak, and it is only able to reach a position close to the indoor unit 2. On the other hand, a signal with a strong radiant intensity can reach a greater distance than a signal with a weak radiant intensity. Further, the infrared light-receiving element (the infrared light-receiving element of the remote control, if it is not input with a signal having a radiation intensity exceeding a certain threshold, cannot be recognized as a signal. Therefore, it is closer to the indoor unit 2 At the position of the signal, it can be used for all signals from the signal with weak radiation intensity until the signal with strong radiation intensity. However, if it is far from the indoor unit 2, it cannot be received. To the signal that the radiation intensity is weak, and only the signal with strong radiation intensity can be received. In this embodiment, the attenuation characteristics of the above-mentioned infrared rays are utilized. As shown in FIG. The machine 2 sends a positional discrimination signal of the radiation intensity of the "strong", "medium", "weak", and "weak" general stages to the remote controller 5. The positional discrimination corresponding to the radiation intensity of the plurality of stages The signal-receiving range of the remote-controlled infrared light-receiving element 41 of the remote controller 5 is generally as shown in FIG. 12, and becomes "far" and "medium" depending on the radiation intensity. Nearly j, "very close" is a range of four stages. That is, it can be defined as follows: the remote control infrared is controlled by -25-201109595 optical element 41, if it can be received, the radiation intensity is "weak" The discriminating signal is that the remote controller 5 is in the "very close" position of the indoor unit 2, and if it is able to receive the position where the radiation intensity is "weak", the remote controller 5 is in the indoor unit 2 At the "near" position, if it is received by the positional signal whose radiation intensity is "medium", the remote control is located at the "middle" position of the indoor unit 2, and if it is only able to receive the position where the intensity is "strong" When the signal is determined, the remote controller 5 is located at the "far" position of the chamber 2. Thus, it can be known that if the remote receiver infrared receiver 4 1 can be always received to the position discrimination signal, The radiance can detect the distance between the indoor unit 2 and the remote controller 5. Therefore, the indoor unit microcomputer 22 is "strong" in order to recognize the radiation intensity of the remote control signal at each stage. ""中", "弱" The "weak" general bit information (injection strength information) is attached to the position discriminating signal. Further, the controller 5 recognizes that the position discriminating signal is transmitted from the indoor infrared illuminating two 32, 33, and 34, and the "left area" and "right area" of the middle area are generally used. The information (area information is added to the position discrimination signal. With this configuration, the remote controller microcomputer 45 can easily recognize that the system has been received from the room by the position discrimination signal received by the infrared light receiving element 41 via the remote controller. The position of the infrared light-emitting diodes 33, 34 is sent to the position discrimination signal, and is judged to be the position discrimination signal until the radiation intensity has been received. Position position number, capable of 5 series radiation internal light The ejaculation is strong and the 5 is attached, and the (radiation makes the telemagnet J, ) is attached to, 32, and the remote control -26-201109595 microcomputer 4 5, the determination result is set to the infrared signal (position result signal) And sent to the indoor unit 2 via the remote control infrared light-emitting diode 42. The indoor unit microcomputer 22 of the air conditioner 1 can detect from the discrimination result of the received infrared signal. The distance from the remote control 5 ("far", "middle", "near", "very close"). In addition, 'the radiation intensity information is added to the position discrimination signal' so it is at the remote control 5 The system does not require a circuit for measuring and discriminating the radiation intensity of the position discrimination signal. In addition, the position result signal transmitted from the remote controller 5 to the indoor unit 2 is set to include the following table. The information displayed in 1 means that the position result signal includes: (1) "remote controller ID" for identifying the remote controller 5 (2) with respect to the detection of the area The "information result of the position discrimination signal" of the position discrimination signal sent from the indoor infrared light-emitting diode 32, (3) is transmitted with respect to the indoor infrared light-emitting diode 3 for detecting from the left area The positional discrimination signal of the position discrimination signal transmitted from the indoor infrared light-emitting diode 34 for detecting the right region is detected by the positional discrimination signal of the position discrimination signal. Received result (5) Information such as "temperature, humidity" detected by the remote controller 5. In addition, the indoor unit 2 (indoor computer microcomputer 22) that receives the position result signal of Table 1 from the remote controller 5 is It is recognized that the remote controller 5 is located at a distance of "near" in the middle area. -27- 201109595

The result of the position discrimination signal (output result information) __ temperature 'humidity zone: weak left zone: strong right zone: strong additionally, in this embodiment In the state, although it is set to identify the distance of 4 stages ("far", "middle", "near", "very close"), it can be signaled by more radiation intensity in the complex stage. Sending a message and detecting the distance more finely. Next, a method of detecting the distance between the indoor unit 2 and the remote controller 5 will be described with reference to the timing chart shown in Fig. 13. In this description, in order to make the description of the distance easy to understand, it is assumed that the general direction of the middle area, the right area, and the left area is not distinguished, that is, the difference between the directions is omitted. First, the remote controller microcomputer 45 transmits the position detection request signal from the remote controller infrared light emitting diode 42 to the indoor unit 2 (time point ta). In addition, the location detection request for the transmission may be set as the sender by the operation of the user, or may be set as the function of the remote controller microcomputer 45 without depending on the operation of the user. . When the indoor infrared light receiving element 18 provided in the indoor unit 2 receives the position detection request signal (the time point ta' which is slightly at the same time as the time point ta), the indoor unit microcomputer 22 is detected in response to the received position. Requesting the signal 'and performing the internal processing as shown in the flow chart of FIG. 6' and sending the -28-201109595 infrared signal (basic operation signal) of the specific transmission code from the indoor infrared light-emitting diode 32 Then, the position discrimination signal e whose radiation intensity is "strong", the position discrimination signal f whose radiation intensity is "middle", the position discrimination signal g whose radiation intensity is "weak", and the radiation intensity are "weak". The position discrimination signal h is sent (time point tb). Here, since there is no difference in direction, the description will be made as the only light-emitting diode 32. In addition, the specific transmission code is, for example, based on the format of the Association of Home Appliances Products. When the remote control infrared light receiving element 4 1 of the remote controller 5 is connected to the specific transmission code (basic operation signal) and the position discrimination signal is received (the time point tb is exactly the same as the time point tb), the remote control The microcomputer 45 discriminates the signal from the received position to determine which of the "strong", "medium", "weak", and "weak" radiation signals can be received. In addition, although the indoor unit 2 is placed indoors in the same manner as the remote controller 5, even if the remote controller 5 is remote from the indoor unit 2 in the same room, only the radiation intensity can be received. Strong position discrimination signal. On the other hand, if the remote controller 5 is in a position very close to the indoor unit 2, the remote controller can always receive the positional discrimination signal whose radiation intensity is "weak". The remote controller microcomputer 45 transmits a position result signal (refer to Table 1) as a result of the discrimination to the indoor unit 2 via the remote control infrared light-emitting diode 42 (time point tc). For example, when the remote controller 5 can always receive a signal until the radiation intensity is "weak", the position result signal includes information indicating "weakness". • 29 - 201109595 When the indoor infrared light receiving element 18 of the indoor unit 2 receives the position result signal, the indoor unit microcomputer 22 detects the distance from the remote controller 5 from the received position result signal. Distance (" far j, "middle", "near j, "very close"). In Fig. 13, for example, the remote control infrared light receiving element 41 receives the position discrimination signals e, f (time point tb'). On the other hand, the position discrimination signals g, h cannot be received. That is, since the signal having the radiation intensity "strong" corresponding to the position discriminating signal e and the signal of the radiation intensity "middle" corresponding to the position discriminating signal f are received, the signal is not received corresponding to the position discrimination. The signal of the "weak" radiation intensity of the signal g and the signal of the "weakness" of the radiation intensity corresponding to the position discrimination signal h can be determined that the distance from the remote controller 5 is "medium". In addition, in order to simplify the description, it is assumed that there is no difference in direction. However, as in the present embodiment, there is an indoor infrared light-emitting diode 3 2 having directivity (refer to FIG. 15). In the case of 3 3 or 3 4, the remote controller 5 receives the position discrimination signal transmitted from the indoor infrared light-emitting diodes 32, 33, 34, and as shown in Table 1, As a result, the position result signal is sent from the remote controller 5 to the indoor unit 2, whereby the indoor unit 2 (the indoor unit microcomputer 22) can detect the remote controller 5 by this (that is, by distinguishing the direction) The more accurate distance β is of course only one example. In order to detect the distance between the indoor unit 2 and the remote controller 5, the bit information (radiation intensity information) is added to the position discrimination signal. However, as will be described later, -30-201109595 is not limited to this example. <Direction Detection by Remote Control> Next, the direction detection method of the remote controller 5 will be described with reference to Fig. 18 . FIG. 14 is a diagram showing the arrangement of the indoor infrared light-emitting diodes provided in the indoor transmitting and receiving unit 16 used for the indoor unit 2 as the remote controller position detecting device, showing the indoor infrared light emitting. Figure 16 of the directivity of the diode is a diagram showing one example of indoor environmental conditions. Fig. 17 is a timing chart for explaining the position detection operation of the remote controller for explaining the correction by the placement position information, as shown in Fig. 14 (a), In the indoor unit 2, the indoor transmitting and receiving unit 16 used for the remote controller position detecting device is provided with three indoor infrared light emitting diodes: the middle area detecting indoor infrared light emitting diode 3, and the left area detecting unit The indoor line light-emitting diode 3 3 and the indoor infrared emitter body 34 for detecting the right area are used. On the other hand, the indoor infrared light-emitting diodes 32, 33, and 34 are expanded in a fan shape and arranged in a direction different from each other in the direction of the difference. Regarding this configuration, it is as described with reference to Fig. 3 and before. As shown in (b) of FIG. 14 , the infrared light-emitting diode 32 for the middle area detection is a transmission position discrimination signal for viewing the front direction (middle area) of the indoor unit from the front side, and the left area is The indoor infrared light-emitting diode 3 3 is used for viewing from the front side. Figure. Figure, diagram. In the case of the 红外 , , 系 红外 红外 红外 红外 红外 红外 红外 红外 红外 红外 红外 红外 红外 红外 红外 红外 红外 红外 红外 红外 红外 红外 红外 红外 红外 红外 红外 红外 红外 红外 红外 红外 红外 红外 红外 红外 红外 红外 红外 红外 红外 红外 红外 红外 红外 红外 红外 红外The light-emitting diodes 34 are for the right-hand direction (right area) when the indoor unit 2 is viewed from the front side, and the transmission position discrimination is performed. In addition, the indoor infrared light-emitting diodes 3 3 and the right area detection for detecting the left area are used. The mounting angle of the indoor infrared light-emitting diodes 34 is such that the indoor infrared light-emitting diodes 3 for detecting the centering region have the same angle on the left and right sides, that is, in this example, The arrangement is such that the overlapping portions of the respective regions are reduced and the ranges of the respective regions are slightly the same. Fig. 15 is for the directivity of the indoor infrared light-emitting diodes (32, 33, 34). The indoor infrared light-emitting diode (32, 33, 34) uses the slightly center of the lens as the optical axis, and radiates infrared rays from the center. Have Directional, that is, the optical axis is set to 0°, and as the angle becomes larger as 10", 20°, the radiation intensity is attenuated and weakened, so that the indoor infrared light emitting diode is The bodies 32, 33, and 34 are respectively disposed in different directions and transmit (radiation) position discrimination signals, and are disposed at positional signals transmitted by the indoor infrared light-emitting diodes disposed in the direction of the position of the remote controller 5 The attenuation of the radiation intensity is minimized, and the attenuation of the radiation intensity of the positional discrimination signal transmitted by the indoor infrared light-emitting diode disposed in other directions becomes larger. Therefore, if it is located toward the remote controller 5 The position discriminating signal from the indoor infrared illuminating diode that has been sent in the direction, the positional signal of the remote controller 5 being sent to the direction of its -32-201109595 is able to A position discrimination signal that is subjected to a weaker radiation intensity, whereby the drive current flowing in the indoor infrared light-emitting diodes 32, 33, 34 is generally set to be detectable from the distance described above. change 'While the radiation intensity is as strong as "strong", "medium", "weak", and "weak" is generally able to discriminate: the positional signal that is sent to the position that can receive the weakest radiation intensity The remote controller 5 is present in the direction in which the indoor infrared light-emitting diode is facing. Another reason for changing the radiation intensity is as follows. Assuming that only a single infrared signal (position discrimination signal) of the same radiation intensity is transmitted, the infrared signal is reflected and directed in a different direction due to indoor environmental conditions such as walls or obstacles. In the case of the transmission, that is, as shown in Fig. 16, in general, when the radiation direction toward the left region is set to A, the radiation direction toward the middle region is set to B, and the radiation toward the right region is to be irradiated. When the direction is set to C, the radiation toward the right region is reflected by the wall in the room and becomes radiation toward the left region (reference symbol C'). For example, although the remote controller 5 is positioned in the left area (refer to the remote controller 5 of the solid line), the remote controller 5 is subjected to an infrared signal that is sent to the right area and is sent to the wrong direction. . However, the reflected infrared signal is weakened due to its long transmission path and is attenuated when it collides with a wall or an obstacle. Therefore, the radiation intensity is weaker than that of the infrared signal directly subjected to the signal. And was accepted. Because -33- 201109595, by making the radiation intensity changeable in the complex phase, since there is a difference in the radiation intensity of the signal to be received, there is no erroneous detection, and it becomes possible. Determine the correct direction. For example, when there is a remote control 5 (refer to the solid line) in the area where the infrared signal of the left area is transmitted to the signal of the "weak" radiation intensity, the infrared light is emitted from the room. The infrared signal (position discriminating signal) sent by the LED 3 3 is able to be received until it is "weak", but is sent to the right area and reflected and is made in the left area. The infrared signal received by the signal is unreachable due to the attenuation of the infrared signal with weak radiation intensity. Therefore, it is a "strong" signal that can only be signaled to be a strong radiation intensity signal. Therefore, it can be discriminated that the remote controller 5 is positioned in the left region of the position discriminating signal that can be always received to the weakest radiation intensity. However, the indoor unit 2 is generally disposed at a position close to a corner of the room because it is placed on the wall surface of the room and avoids the position of the window or the like. Therefore, there are many indoor environmental conditions that cause reflection as described above. Therefore, in the present embodiment, it is assumed that the setting of the adjustment can be performed in accordance with the indoor environmental conditions when the indoor unit 2 is set at the position. For this point, reference is made to the flowchart of FIG. After the indoor unit 2 is placed, it is determined whether or not the indoor unit 2 is set in the indoor unit microcomputer 22 (S11). In the present embodiment, the decision of S11 is dependent on the judgment of the user. When the result of the decision to use -34-201109595 at S11 is that the setting is not made, the "no setting" instruction is used as the infrared signal by the remote controller 5 in response to the user's operation. The indoor unit microcomputer 22 commands (S12), and the indoor unit microcomputer 22 directly performs normal determination (S1 3). Further, if the initial state of the indoor unit microcomputer 22 is "no setting", the S 1 2 system can be omitted. On the other hand, when the result of the determination by the user at S11 is that the setting is made, the "set" indication is passed through the remote controller 5 as an infrared signal for the indoor unit in response to the user's operation. The microcomputer 22 commands (S14), and the next step is made by the user. That is, when the setting of the wall is immediately on the left side of the indoor unit 2, the instruction of "the wall exists on the left side" is used as the infrared signal by the remote controller 5 by the operation of the user. The indoor unit microcomputer down command (S 1 5 ), and the indoor unit microcomputer 22 performs an adjustment (S16) of increasing the output result information of the position result signal of the left area as the α stage, and performs the adjustment according to the adjustment. The usual decision (S17). Moreover, when the setting of the wall is immediately adjacent to the right side of the indoor unit 2 as shown in FIG. 16, the indication that "the wall exists on the right side" is passed through the remote controller 5 by the user's operation. As an infrared signal, for the indoor unit microcomputer down command (S 18), the indoor unit microcomputer 22 performs an adjustment (S19) of increasing the output result information of the position result signal of the right area as the α stage (S19), and performs the basis. The normal judgment after this adjustment is made (S20). -35- 201109595 That is, it is assumed that there is a remote controller 5' at the position shown by the dotted line in Fig. 16. As a result, the remote controller 5' is capable of emitting infrared diodes from the room. The position discriminating signals sent by the 32, 33 and 34 respectively have been received until the "weak". Therefore, when it is assumed that the position result signal transmitted from the remote controller 5' is as in the case of Table 2 below, the indoor unit microcomputer 22 cannot determine where the remote controller 5' exists. However, if the "wall exists on the right side" is set in the indoor unit microcomputer 22 as in S18, the indoor unit microcomputer 22 outputs the right area of the position result signal of the table 2 as in the case of S1 9 . The result information (radiation intensity) is corrected in two stages (α = 2), that is, from "weak" to "strong", so that the position of the remote controller 5' can be correctly identified. That is, when it is assumed that the remote controller 5' is present at the position shown by the broken line in Fig. 16, the position discrimination signal transmitted from the indoor unit 2 toward the right area is originally at the remote controller 5. 'The department can't detect it, or even if it can detect it, it can only detect the radiation intensity is "strong". In the present embodiment, by setting the matter (there is a wall on the right side) in the indoor unit microcomputer 22 (S18), the indoor unit microcomputer 22 is capable of the general remote controller 5 as shown in Fig. 16. 'It is correctly judged (S20) for the direction in the vicinity of the boundary between the middle region and the left region. In addition, although there is a difference between the left side and the right side in the idea of this matter, it is the same in the above S15 to S17. • 36- 201109595 [Table 2] Remote control Π) H IS·, 丨, 口木ΠΑ方 tc Position discrimination signal of the received result (Μ -, 1 cough It 刖 ii results information)) Temperature, humidity in the area : weak left area: weak right area: weak position result signal example (correction. After) remote control ID position discrimination signal training result ii out result information) temperature, humidity area: weak left area: weak right area: strong target The position result signal, after receiving the signal, the indoor unit microcomputer 22 is modified for the right area. In addition, when the setting of the wall is adjacent to both sides of the indoor unit 2, the instruction of "there is a wall on both sides" is used as the infrared signal by the remote controller 5 by the user's operation. The indoor unit microcomputer down command (S2 1 ), and the indoor unit microcomputer 22 performs the adjustment (S22) of the increase of the α-stage correction result information of the position result signals of the left and right areas and performs the adjustment according to the adjustment. Determination (S23) ^ The idea of this point is also the same as that of the aforementioned S 18 to S20. That is, in the present embodiment, as shown in FIG. 17, generally, by setting whether the left, right, or both sides of the indoor unit 2 are placed at the wall side in the air conditioner 1 is set. Means, the system configuration is: When it is set to be in the case of the wall edge, the output of the position discrimination signal is adjusted for the correction of the specific stage, and the detection of the error caused by the reflection can be further avoided. Composition. Further, in the present embodiment, the indoor environmental condition is set by the user via the remote controller 5. However, for example, a DIP switch (not shown) may be provided at the indoor unit 2. (Dual ln-line -37- 201109595

Further, in the present embodiment, the output result information of the position result signal transmitted from the remote controller 5 is adjusted by the indoor unit 2 (the indoor unit microcomputer 22) (refer to Table 2). However, this department is only one of them. For example, it is also possible to correct the current position of the indoor infrared light-emitting diodes 3 2, 3 3, and 3 4 when the position determination signal is transmitted to the remote controller 5 (Adjustment). Further, it may be set such that the correction of the output result information (radiation intensity) at the position result signal shown in Table 2 is performed by the remote controller 5 (remote controller microcomputer 45) that generates the position result signal, and The corrected position result signal (refer to the table below Table 2) is sent to the indoor unit 2. In this case, the setting of the indoor environmental conditions is performed on the remote controller microcomputer 45, for example, in accordance with the flowchart of FIG. Further, for example, when the setting is "there is a wall on the right side", it is set as the output result information (radiation) of the right region of the position result signal received from the remote controller 5 as in S1 9 . The intensity is corrected by the alpha phase. However, for example, the correction of the output result information may not be performed, and the distance corresponding to the output result information may be corrected. Specifically, when the setting of the "wall on the right side" is set, if the output result information* in the position result signal received by the indoor unit microcomputer 22 is the "weak" shot intensity in the right area, It can be set as follows: the output result information is not corrected, but the distance is corrected and discriminated as in the "middle" mode. That is, it is also possible to set the correspondence between the radiation intensity and the distance shown in Fig. 12 in accordance with the setting of the indoor environmental conditions. The idea of this point is the same when it is set to "there is a wall on the left side". Further, when there is substantially no indoor environmental condition in the right region as shown in Fig. 16, the operation of the indoor infrared light-emitting diode 34 for detecting the right region may be stopped. The idea of this point is the same when the setting of "there is a wall on the left side" (that is, the case where there is substantially no left area). Next, the operation of the position detection of the remote controller 5 will be described with reference to the timing chart of Fig. 18. This timing chart is based on the flowchart of Fig. 6. First, the remote controller microcomputer 45 transmits the position detection request signal to the indoor unit 2 via the remote control infrared light-emitting diode 42 in response to the operation of the operation key 65 (time point tj). When the indoor infrared light receiving element 18 provided in the indoor unit 2 receives the position detection request signal from the remote controller 5 (the time point tj ' at the same time point tj), the indoor unit microcomputer 2 2 The internal processing is performed in response to the received position detection request signal, and the infrared signal of the specific transmission code is simultaneously transmitted from the indoor infrared illuminating diodes 32, 33, 34 (time point tk). The same as the above, the specific transmission code ′ is equivalent to the basic operation signal of Fig. 11. For example, it is based on the format of the Institute of Home Appliances. The infrared signal of the specific transmission code is received by the infrared light receiving element 4 ! at the time point tk' at the same time as the time point tic -39 - 201109595. Next, the indoor microcomputer 22 is an outdoor line light-emitting diode 32 for detecting the medium area, and sequentially transmits the discrimination signal e of the "strong" radiation intensity and the position discrimination signal f and the radiation of the radiation intensity "middle". The weak position is determined by the signal g and the radiation intensity "weak" position signal h (time point tm). Next, the indoor microcomputer 22 detects the position (e, f, g, h) (time point tn) of the position of the indoor infrared light-emitting diode 3 for area detection. The indoor microcomputer 22 is connected to the indoor infrared emitter 3 4 for detecting the right region, and sequentially transmits the same position discrimination signal (e, f, g, (time point tp). The position discrimination signal from the diode (32, 33, 34) is based on the way that the infrared light-emitting diode from which the infrared light-emitting diode is sent is added, and the "domain" is added. The general direction information (information) of the "area" and the "right area", and the "strong", "medium", "weak" and "weak" general spokes are added in a way that can identify the radiation intensity of the area. In contrast, the remote controller microcomputer 45' on the remote controller 5 side is attached to the remote control infrared light receiving element 41, and is slightly at the same time point tm' as the time point tm and the time point tn. The point tn ', the point tp is slightly at the same time point tp ', and the received position discrimination is in Fig. 18. At the time point tm ', the positional discrimination signal is transmitted by the inner red position. Set the judgment from the left news, light two h) sent the indoor zone knowledge , Mediated by the strong radio time signal and time. -40- 201109595 f, at the time point tn ', the position discrimination signal e, f, g is received, and at the time point tp ', the position discrimination signal e is received. Then, the remote controller microcomputer 45, when all the position discrimination signals are received at the time point tp', receives the received result of the position discrimination signal as the position result signal (reference table) 1), and is sent to the indoor unit 2 via the remote control infrared light-emitting diode 42 (time point tr). When the position result signal is received by the indoor infrared light receiving element 18 provided in the indoor unit 2 (the time point tr' which is slightly at the same time as the time point tr), the indoor unit microcomputer 22 is received from the receiver. The location result signal is used to determine which position discrimination signal is detected in the "stronger to weaker middle zone", "stronger to weaker zone", and "stronger to weaker zone" and detected. The distance and direction (ie, position) from the remote control 5. In the example shown in Fig. 18, the remote control infrared light receiving element 41 of the remote controller 5 is "strong" in the position discrimination signal transmitted from the indoor infrared light emitting diode 32 for detecting the middle area. And "Zhong" and "Weak" and "Weak" in the position discrimination signal sent from the indoor infrared light-emitting diodes 3 3 for detection from the left area, and received There is a "strong" in the position discrimination signal transmitted from the indoor infrared light-emitting diode 34 for detecting the right area. As a result, the remote controller microcomputer 45 transmits the received result of the position discrimination signal as a position result signal to the indoor unit 2 via the remote control infrared light-emitting diode 42 ( Time point -41 - 201109595 tr) When the positional result signal is received by the indoor infrared light receiving element 18 of the indoor unit 2, the indoor unit microcomputer 22 is based on the received position result signal. Perform calculations. In the example shown in Fig. 18, > among the three position result signals, the position is judged by the position transmitted from the indoor infrared light-emitting diode 33 for the left-side field detection 5H 57Λ It has been received until the weakest radiation intensity y. Therefore, the direction of the remote controller 5 is set to the factory left area J, and since the distance system can be directly received to the factory weak J, it is set as the factory near j) and the position of the remote controller 5 is determined as the factory left. The area i field is near _ 1 , and: the distance from the remote controller 5 is set to the factory near J > the direction is set to the factory left area j, and When the position of the remote controller 5 is detected as 0, by the present embodiment, the air conditioner 1 that performs the two-way communication between the indoor unit 2 and the remote controller 5 is maintained in the infrared transmission and reception system using the ριτ wi Under the state > by emitting the infrared light The driving current of the diode is set to be variable. ♦ The position of the remote controller can be detected easily and at low cost without separately setting a dedicated system. In addition, the remote control user can also be used by the prior art bidirectional communication function. In the above-described embodiment, although the radiation intensity of the indoor infrared light-emitting diodes 32, 33, and 34 of the indoor unit 2 is variable, the radiation intensity of the indoor infrared light-emitting diodes 32, 33, and 34 may be changed. It is assumed that the radiation intensity of the remote control infrared light-emitting diode 42 of the remote controller 5 is made variable, and the distance is detected by the received result of the indoor infrared light-receiving element 18. -42- 201109595 Further, it is also possible to set a plurality of indoor infrared rays 1 to 8 and arrange them in a predetermined direction as the indoor infrared light-emitting diodes 3 2, 3 3 and the ground, and then The result of the reception of the indoor light component detects the direction of the remote controller 5. Further, in the present embodiment, the information of the radiation intensity is added to the position discriminating signal. However, as a state, it is also possible to prepare a pulse in the interval of A to X and to pulse the section. The radiation intensity is "strong", and the C to D area is set to the radiation intensity "medium", and the pulse setting in the E to F section is "weak", and the pulse in the G to Η interval is set as radiation! Weak", to send the message to the middle area, similarly, the pulse with the change of the radiation intensity at I~Ρ is sent to the left area, and the radiation intensity will be changed in each interval of Q~X. The right side of the vein. Then, the radiation intensity at (middle, left, and right) is detected by counting the pulse of which one can be at each region. Fig. 19 is a view showing a concrete example of the case where the interval from Α to X is used. For example, the interval of A to B, the interval of C to D, the interval between E and G to Η is fixed to 30 pulses of a certain period, and the position discrimination signal whose intensity has changed is sent to the middle region. The pulse of each interval of I~Ρ is sent to the left area as a position discrimination signal, and the pulse of Q~X is used as a position discrimination signal for changing the radiation intensity to receive the infrared light of the light receiving element 34. As a bit, he implements the pulse between the type Α~Β as the intensity of the radiation. The area of the same rushing signal to the pulse of the area 5 that has been received by the signal is used as the undulation, and the same The change of each section is sent to the right-43-201109595 area. When the remote control side of the infrared signal is sent to the indoor unit 2, the indoor unit microcomputer 22 can be used by each The field (middle, left, right) and the received result of each radiation intensity are detected by the direction and distance of the remote device 5. In addition, if the remote controller 5 is located near the indoor unit 2, the system can count To the majority of the pulse. In addition, this The time pulse is a pre-determined infrared signal of 38 kHz, DUTY 50%, etc. Further, as another embodiment, it is also possible to set the timing from 11 to t24 seconds. For t2 seconds, set the radiation intensity to "strong", and set t3 seconds to t4 seconds to the radiation intensity "medium", and set the seconds to t6 seconds to the radiation intensity "weak", and then set t7 seconds to t8 seconds as the radiation intensity. "Weak", and sent to the middle area, the same, at each time t9 ~ 11 6 seconds, the radiation intensity is changed, and sent to the area, the same, in tl7 seconds ~ t24 seconds At each time, the intensity of the radiation is changed and sent to the right area. Then, the radiation intensity map 20 in each region (middle, left, and right) is detected by the time when it can be always received for each region, and is shown for A diagram showing a specific example of the timing when t24 seconds are counted. For example, 'the position discrimination signal that changes the radiation intensity at the time of t1 to t2, t3 to t4, t5 to t6, and t7 to t8 is sent to the area in the transmission, and the same is taken as the t9 to t16. At each time, the positional discrimination signal whose spoke intensity is changed is sent to the left area, and the radiation intensity is changed to the first time at each time of tl 7~t24. Degree t5 irradiance is left to the right area at the position of the 〇 各 • 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 When the result of the remote control side of the infrared signal is sent to the indoor unit, the indoor unit microcomputer can receive the result of each radiation intensity by each area (middle, left, right). , to detect the position by the direction and distance of the remote control. Further, if the remote controller 5 is located in the vicinity of the indoor unit 2, it can be received for a longer period of time. Further, the timing from 11 seconds until t24 seconds is started as the to second when the termination bit representing the end of the basic information among the basic information attached to the basic operation signal. In addition, the timing signal uses an infrared signal having a predetermined decision of 38 kHz, DUTY 50%, and the like.
