Abstract

PURPOSE:To use effectively reflected light by changing the height and the direction of a light emitting element to search the receivable state and arranging a device most suitably to a room where the device is installed and for the use. CONSTITUTION:If reception is impossible though a reception confirming test switch 15 is depressed after installing the device, the height and the direction of a case 12 to which a light emitting element 3 is fixed are regulated by freely contractible and expansible metallic fittings 14 and a flexible supporting tool 13, and the receivable position is searched while depressing the switch 15. Metallic fittings 14 are expanded to perform direct transmission even if an obstacle 16 is interposed, and the position where reception is possible by reflection on a floor 9, a wall surface 10, and a ceiling 11 is searched if direct transmission is impossible. Thus, the height and the direction of the light emitting element are changed without moving the device body to obtain the receivable state.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to an infrared wireless automatic control device that automatically controls equipment at a remote location using an infrared transmitting device built into the equipment.

Conventional technology This type of control device is based on the relationship between the installation positions of equipment on the transmitting side (for example, air conditioners, fan heaters, etc.) and equipment on the receiving side (for example, ventilation fans, humidifiers, etc.) based on the layout of the room. From the beginning, the positional relationship is often limited to some extent, and the positional relationship is often not ideal, such as when used in a facing position, such as with a television remote control device.

Therefore, in order to ensure reliable reception in conventional devices of this kind, for example, as shown in FIG.
and 4 are installed so that the orientation of 3 is vertical and the orientation of 4 is horizontal.On the other hand, the light receiving elements of the infrared receiving device 6 incorporated in the receiving device 5 are also installed with 7 and 8. They were installed so that 7 was oriented vertically and 8 was oriented horizontally, so as to make effective use of the reflection of infrared rays from the floor 9, wall 10, and ceiling 11. .

Problems to be Solved by the Invention However, such conventional means are not only affected by the reflection characteristics of walls, etc., but also because the transmission direction is fixed, the positional relationship between the transmitting side equipment and the receiving side equipment and their If there is a light blocking object such as furniture in the way, reception may not be possible depending on how it is placed, and in such cases, even if you ignore the good positional relationship of each device in the room. However, there is a problem in that either the transmitting device or the receiving device must be forcibly moved to a location where it can receive data.

Means for Solving the Problems In order to solve these problems, the present invention provides a method for attaching the light emitting element of the transmitting device incorporated in the transmitting side equipment to the tip of a retractable metal fitting, and for adjusting the radiation direction of the light emitting element. It is mounted so that it can be rotated freely, and a test switch for confirming reception is provided on the transmitting device.

If no reception is received even after pressing the test switch for confirming reception using the above method, change only the height and direction of the light-emitting element while leaving the transmitting device in the same position, and then press the test switch to locate the light-emitting element that can receive data. You can search by pressing.

EXAMPLE Hereinafter, an example of the present invention will be explained with reference to FIG. 1st
In the figure, 1 is a transmitting device, 2 is a transmitting device incorporated in 1, 3 is a light emitting element, 12 is a case for fixing 3,
13 is a flexible support that supports 12, 14 is 13
15 is a test switch for confirming reception.

In the above configuration, if reception is not received even after pressing the test switch 15 for confirming reception after installing the device, adjust the height and direction of the case 12 in which the light emitting element 3 is fixed using the telescoping metal fitting 14 and the flexible support 13. , you can search for a position where reception is possible while pressing the test switch 15. Furthermore, even if there is an obstacle 16 on the way, direct transmission is possible by extending the metal fitting 14, and even if direct transmission is impossible, it is appropriate to receive by reflection from the floor 9, wall 10, and ceiling 11. You can search for a suitable location. In addition, 5 is a device on the receiving side, and 6 is built into 5. According to the infrared wireless automatic control device of the present invention, reception is possible by simply changing the height and direction of the light emitting element without moving the device itself. By being able to find the condition of the equipment, you can not only choose the most suitable equipment placement for the room where the equipment is installed and its intended use, but also the positioning of the equipment as long as it is within the reach of the reflected light even if there is an obstacle in the way. (no walls or sliding doors).
