Abstract

PURPOSE:To suppress the contamination degree of the room to a predetermined value by detecting the contamination degree of the room by means of contamination degree detecting mechanisms and controlling the operations of an electric dust collector, and a fan by a control circuit, in the titled air cleaner. CONSTITUTION:The contamination degree detecting mechanism 12 detects the contamination degree of air within the room, and transmits a signal for instructing the operations of the electric dust collector 8 and the fan 9 to a control circuit 11. Thus, the surplus driving of the air cleaner is prevented, and environmental sanitary problems generated by the individual difference of air cleaner users who sense the air contamination degree can be removed.

Description

[Detailed description of the invention] Industrial use! 111・ The present invention relates to an air cleaner.

Conventional configuration and its problems Conventional air purifiers have filters 1 and 4 as shown in Figure 1.
, an electric dust collector 2, a fan 3 for sucking and blowing out air, and a power switch 5. The air purifier is operated by a person who senses the level of contamination in the room and turns on the power switch 6. This is done by Note that 6 is a power source. Similarly, the air cleaner is stopped by a person sensing the degree of contamination in the room and turning off the power switch 5.

However, in general, there are individual differences in how people perceive the degree of pollution in a room, so when operating an air purifier, it is important to avoid operating the air purifier excessively or even if the air in the room is polluted. However, there are cases where the air purifier cannot be operated properly.

In the former case, such a situation leads to excessive consumption of electricity, and in the latter case, it does not have an adverse effect on the human body in terms of environmental health.

OBJECTS OF THE INVENTION The present invention obviates the drawbacks of the prior art and aims to keep the degree of indoor contamination at a constant level.

Structure of the Invention In order to achieve this object, the present invention provides a control circuit for controlling the pollution degree detection function and the operation and stop of the electric dust machine and the fan, and detects the pollution degree of the room by the pollution degree detection function. Control 1! This is to control the operation of the fan in the electric dust machine section through the JL path.

DESCRIPTION OF EMBODIMENTS Below, an embodiment of the present invention will be described with reference to FIGS. 2 to 4.

In the figure, 7.10 is a filter, 13 is a power switch, and 14
indicates a 7L source.

When the power switch 13 of the air purifier shown in FIG. Electric dust machine 8 and fan 9
Sends a signal to instruct the driver to operate the vehicle.

Next, when the control circuit 11 closes the output contact 8a of the electric dust machine 8 and the output contact 9a of the fan 9 shown in FIG. 3, the air cleaner starts operating and purifies the air.

Next, as shown in FIG. 4, after the air purifier is operated, the air is purified and the pollution level in the room becomes below the environmental standard level, and when this is detected by the pollution level detection function 12, the pollution level detection function 12 sends a signal to the control circuit 11 to stop the operation of the electric dust machine 8 and the fan 9. And production.”
1 circuit 11 opens the output contact 8a of the electric dust machine 8 and the output contact 9a of the fan 9, and
stop operating.

Next, after the electric dust machine 8 and the fan 9 are stopped, when the pollution level in the room increases and becomes below the environmental standard level, the ilG pollution level detection function 12 detects that the air pollution level is above the environmental standard level. Upon detecting this, the air purifier starts operating the electric dust machine 8 and fan 9 in the same manner as described above.

Similarly, the air purifier operates the electric dust machine 8 and fan 9 when the degree of pollution in the room is above the environmental standard, and operates the electric dust machine 8 and fan 9 when it is below the environmental standard. Perform the action to stop operation. Note that the control circuit is configured to have a certain degree of differential between the ON point (, φU rotation) and OFF point (stop) of the electric dust machine 8 and the fan 9.

As mentioned above, the air purifier operates according to the pollution level of the room, so if the pollution level of the room is below the environmental standard level, the output contacts 81L and 9a of the electric dust machine 8 and fan 9 shown in FIG. This has the advantage of avoiding unnecessary power consumption because no current is applied and only the control circuit is operating. It has the advantage of being able to purify the air regardless of individual differences between users by controlling the degree of contamination of the air in accordance with environmental standard levels.

Effects of the Invention As is clear from the above, the air cleaner of the present invention has a detection function for detecting air pollution, and controls the operation and stopping of the electric dust machine and fan in the air cleaner depending on the degree of air pollution. A circuit is installed to turn on (operate) the electric dust machine and fan and turn it off (off) according to the degree of contamination in the room.
This system prevents over-operation of air purifiers, which was a problem with conventional devices, and eliminates environmental hygiene problems caused by individual differences in how air purifier users perceive the degree of air pollution. It is effective.
