Abstract

PURPOSE:To raise the circulation efficiency of air and to improve the dust collecting capacity by providing two ultraviolet ray detecting sensors with a partition at the center between them, detecting the direction of a flame by the combination of two sensors, and changing the direction of the discharge air or the suction air. CONSTITUTION:The ultraviolet ray detecting sensors 2, 3 are disposed in front of a main body 1, and the partition is provided between these sensors 2, 3. When the air cleaner is put into operation and the flame 14 of a lighter, etc., is located at a position A, both sensors 2, 3 detect the flame and an actuator 13 moves the blades 9 of louver 8 to turn to the direction A. When the flame 14 is located at the position B or C, only one sensor of the sensors 2, 3 detects the flame and the actuator 13 moves the blades 9 of louver 8 to turn them to the direction B or C, and the air circulation of the place where the flame is generated is promoted.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to an air purifier that automatically operates by detecting flames from lighters, matches, etc.

2. Description of the Related Art Conventionally, as shown in FIG. 4, this type of air purifier has an ultraviolet detection sensor 20 that detects ultraviolet rays contained in the flame of a lighter or a matchstick, which is disposed on the front of the main body. The electric blower was started.

Problems to be Solved by the Invention In general, an air purifier removes air pollution caused by cigarette smoke. However, depending on the location of the air purifier in the room and the direction of the air purifier's intake and exhaust, air circulation may be affected, and dust collection efficiency may deteriorate depending on where smoke is generated. Some devices have a louver installed in the exhaust port so that the direction of the exhaust can be varied, but the user must operate the device to match the direction of the smoke being generated, in order to collect dust efficiently. .

Means for Solving the Problems In order to solve these problems, the present invention provides two ultraviolet detection sensors, a partition in the center of these sensors, and a combination of the outputs of the two sensors to determine the direction of the flame. Determine this and change the direction of exhaust or intake.

Effects According to the present invention, it is possible to provide an air purifier that improves air circulation efficiency in the direction in which smoke is generated and has good dust collection efficiency.

Example Embodiments of the present invention will be described with reference to the accompanying drawings.

In FIG. 1, ultraviolet detection sensors 2 and 3 are arranged on the front surface of a main body 1, and a partition 4 is provided between these ultraviolet sensors 2 and 3. Wind enters through the intake port 5 and exits through the exhaust port 6. 7 is a hand controller provided for manual operation. FIG. 2 shows a looper 8 installed at the exhaust port or the intake port 6. This configuration consists of several blades 9 arranged in a row,
Support points 11 and 12 are provided at both ends of the blade 9, the support point 11 enters the wall of the exhaust port, and the support point 12 is supported by the movable plate 1o. An actuator 13 for moving the movable plate 1Q is connected to the movable plate 1Q, and the blade 9 is moved by the operation of the actuator 13.
moves left and right.

In the above configuration, the operation of the air purifier depending on the position of the flame will be explained based on FIG. 3, which is a top view of the room in which the air purifier is placed. When the flame 14 is at position A, both the ultraviolet detection sensors 2 and 3 detect it. Therefore, when these two ultraviolet detection sensors 2゜3 detect both, the actuator 13 operates so that the blade 9 of the looper 8 faces in the direction A, the exhaust gas flows in the inlet direction, and the air in the inlet direction is improve circulation. Similarly, when the flame 14 is at position B or position C, only one of the ultraviolet detection sensors 2 and 3 detects it. Therefore, when only the ultraviolet detection sensor 2 or 3 is detected, the actuator 13 operates so that the blade 9 of the looper 8 faces in the direction B or C, and the exhaust gas flows in the direction B or C. Improve air circulation in direction C.

Although the exhaust port has been described above, the same applies to the intake port.

Effects of the Invention As described above, according to the present invention D'C, an air purifier can be provided that detects the location where a flame is generated, improves the circulation of air in that direction, and has high dust collection efficiency.
