Description

The present invention relates to an apparatus for deodorizing indoor air in the process of circulating indoor air.

Photocatalysts are also used in indoor air circulation devices, so-called circulators, but unless the circulators are capable of satisfying the air circulation capability, the decomposition function of the photocatalyst cannot be fully exhibited. In addition, since most conventional circulators are manually turned on and off, the air circulation capacity of the circulator is constant regardless of whether there is a large temperature difference in each part of the room, which is preferable from the viewpoint of energy saving. It is not a thing.

A thermometer that detects the difference is connected, the photocatalyst layer is decomposed by the ultraviolet rays from the ultraviolet lamp, the indoor air passing through the air intake is deodorized, and the temperature difference is output from the thermometer. Based on the speed control drive circuit, the motor speed is controlled, and at the same time, the brightness of the ultraviolet lamp is controlled by the lighting dimming circuit. It is (claim 2).

According to claim 1, a strong and highly directional tornado-like vortex is generated by the propeller fan and a large number of spiral-shaped blades in front of the propeller fan, and this tornado-like vortex sufficiently circulates indoor air The temperature of the indoor air can be made uniform, and the photocatalyst layer can be decomposed by the ultraviolet light from the ultraviolet lamp, so that the indoor air is deodorized, antifouling (self-cleaning) and antibacterial Function can be expected.

According to claim 2, in addition to the effect of claim 1, the speed of the motor is controlled by the speed control drive circuit based on the output of the temperature difference from the thermometer, and at the same time, the brightness of the ultraviolet lamp is controlled by the lighting dimming circuit. Therefore, the air circulation capability of the indoor air circulation device and the decomposition function of the photocatalyst can be automatically adjusted according to the temperature difference in the room, thereby realizing energy saving.

1 and 2 show an indoor air circulation device 1 with a deodorizing function according to the present invention. As can be seen from FIGS. 1 and 2, the indoor air circulation apparatus 1 with a deodorizing function according to the present invention has a blowout port 14 in front of a propeller fan 4 that is driven to rotate by a motor 3 in a trumpet-shaped duct 2. In addition, a large number of spiral blades 5 are provided on the front surface, and a plurality of fins 8 having a photocatalyst layer 7 on the surface and an ultraviolet lamp 9 facing the photocatalyst layer 7 are provided in the air intake port 6 formed on the back surface of the propeller fan 4. The arrangement is arranged.

The trumpet-shaped duct 2 is fixed to the main body case 16 together with the annular outer case 15, and the main body case 16 forms a large number of fins 8 at the position of the air intake port 6 leading to the blowout port 14. Yes. In this example, a large number of fins 8 extend radially from the outer peripheral surface of the air intake port 6 toward the rotating shaft 17 of the propeller fan 4 and from the outer peripheral surface of the air intake port 6 in the radial direction. It is comprised with what extends to. These fins 8 have a photocatalytic layer 7 on the surface. The constituent material of the photocatalyst layer 7 is typically titanium dioxide, but other materials can also be used depending on the required function.

The ultraviolet lamp 9 is for causing a photocatalytic reaction to occur in the photocatalyst layer 7, and a total of six reflectors around the rotating shaft 17 of the propeller fan 4, for example, every 60 degrees toward the photocatalyst layer 7 of the fin 8. 18 together. The indoor air circulation device 1 with a deodorizing function can be supported by the stand 22 of the outer case 15 so that the angle can be adjusted.

FIG. 3 shows a circuit attached to the indoor air circulation device 1 with a deodorizing function of the present invention. As shown in FIG. 3, according to the present invention, in the indoor air circulation apparatus 1 with the deodorizing function, the speed control driving circuit 10 is connected to the motor 3 and the lighting dimming circuit 11 is connected to the ultraviolet lamp 9, respectively. A thermometer for detecting a temperature difference between the upper and lower parts of the room, for example, a thermocouple type thermometer 12 is connected to the drive circuit 10 and the lighting dimming circuit 11. Both the speed control drive circuit 10 and the lighting dimming circuit 11 are connected to the power supply unit 13 and the changeover switch 19, and are connected to the speed adjustment knob 20 and the dimming knob 21, respectively.

When the user turns on the power supply unit 13 and sets the changeover switch 19 to the manual side, the output of the thermometer 12 becomes invalid, and the speed adjustment knob 20 and the dimming knob 21 function instead. The user operates the speed adjustment knob 20 to adjust the rotational speed of the motor 3 and also adjusts the brightness of the ultraviolet lamp 9 by operating the dimming knob 21 to appropriately circulate the indoor air with a deodorizing function. Device 1 is used.

When the user sets the changeover switch 19 to the automatic side while the power supply unit 13 is on, the output of the thermometer 12 becomes valid, and the speed adjustment knob 20 and the dimming knob 21 do not function instead. Become. At this time, the output of the thermometer 12 detects the temperature difference between the upper and lower parts of the room and sends the output proportional to the temperature difference to the speed control drive circuit 10 and the lighting dimming circuit 11.

For this reason, the speed control drive circuit 10 drives the motor 3 based on the output of the temperature difference from the thermometer 12, and rotates the propeller fan 4 at a high speed when the temperature difference is large and at a low speed when the temperature difference is small. . Further, the lighting dimming circuit 11 turns on the ultraviolet lamp 9 based on the output of the temperature difference from the thermometer 12, and turns on the brightness when the temperature difference is large and dimmes when the temperature difference is small. Turn on.

FIG. 4 shows the operation of the indoor air circulation device 1 with a deodorizing function of the present invention. Due to the rotation of the propeller fan 4, the air that has entered from the air intake 6 becomes a strong and highly directional tornado-like vortex by the numerous spiral blades 5 at the position of the outlet 14. This tornado-like vortex circulates indoor air sufficiently. As a result, the temperature of the indoor air can be reliably made uniform.

In addition, since the indoor air circulation apparatus 1 with a deodorizing function is normally attached to the height position in the middle of the indoor side wall, the strong and highly directional tornado-like vortex becomes a horizontal air flow, It hits the opposite wall and changes direction, creating an air circulation in the room. Of course, the attachment position (installation position) may be on the floor or the ceiling surface.

At the same time, the photocatalyst layer 7 receives the oxidizing power of ozone generated by ultraviolet rays and discharge from the ultraviolet lamp 9, and performs a strong decomposing action on indoor air passing between the fins 8 of the air intake port 6. In addition to deodorizing air, it exhibits antifouling (self-cleaning) and antibacterial functions.

Further, the speed control drive circuit 10 controls the speed of the motor 3 based on the output of the temperature difference from the thermometer 12, and the lighting dimming circuit 11 controls the brightness of the ultraviolet lamp 9 at the same time. Accordingly, the air circulation capability of the indoor air circulation device 1 and the decomposition function of the photocatalyst layer 7 are automatically adjusted, so that energy saving can be realized.
