Abstract

(57) [Abstract] [Purpose] To be able to accurately know the contamination caused by the increase of carbon oxide concentration in the indoor air while using the indoor air treatment equipment. [Structure] A sensor 21 for detecting a carbon oxide concentration or an oxygen concentration in a main body case 10 of an indoor air treatment equipment, and an informing means 22 for informing by a display or an alarm or both of them.
And a control means 23 for operating the notification means 22 based on the detection result of the sensor 21. And the sensor 21
The carbon oxide concentration or oxygen concentration is detected by the control means 23.
When it is determined that the concentration of carbon oxide in the indoor air has risen above a certain value, the control means 23 activates the notification means 22 to display or give an alarm or both.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an indoor air treatment device for treating indoor air, such as an air purifier, an air conditioner, a fan heater, and a stove.

[0002]

[Prior Art]

 Conventionally, for example, in the case of a stove, if it is used for a long time in a closed room, the carbon oxide concentration will rise and it will adversely affect the human body. There was one that turned on the display prompting. However, no measures were taken against air pollution due to an increase in carbon oxide in other air purifiers.

[0003]

[Problems to be solved by the device]

 However, even in the conventional stove, it was not possible to accurately know the contamination due to the increase in the carbon dioxide concentration in the indoor air due to the difference in the indoor environment and the indoor space. Moreover, in the air purifier and the like, it was not possible to know the above-mentioned contamination of the room air.

Therefore, an object of the present invention is to make it possible to accurately know the contamination due to the increase in the carbon oxide concentration of the indoor air while using the indoor air treatment equipment.

[0005]

[Means for Solving the Problems]

 Therefore, the present invention is, for example, as shown in the following illustrated embodiments, a sensor 21 for detecting the carbon oxide concentration or oxygen concentration in the indoor air, a notifying means 22 for notifying by a display or an alarm or both of them, and And a sensor control device 23 that operates the notification means 22 based on the detection result of the sensor 21.

[0006]

When the sensor 21 detects the carbon oxide concentration or the oxygen concentration and the sensor control device 23 determines that the carbon oxide concentration of the indoor air has risen to a certain value or more, the sensor control device 23 notifies the alarm means. 22 is activated to give a display, an alarm, or both.

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is an external perspective view showing an air purifier. Reference numeral 10 indicates a main body case. The body case 10 has a box shape, and an air outlet 11 is provided at an upper portion of the front surface thereof, and an air inlet 12 is provided at a lower surface thereof. Further, a window 10a is provided in the lower part of the front surface, and the display means 13 is provided in the window 10a. An operation switch 15 is provided outside the main body case 10 so as to be electrically connected to a control device 20 described later in the main body case 10 via a lead wire 14. On the other hand, in the main body case 10, as shown in FIG. 2, a dust collector 16, a fan 17, a fan motor 18, a smoke sensor 19 and a controller 20 electrically connected to them. Equipped with.

Then, the operation switch 15 drives the fan motor 18 through the control device 20 to rotate the fan 17, thereby taking in air from the suction port 12 in the direction of arrow A in the drawing, and taking in the taken air. After the smoke and dust are adsorbed by the dust collector 16, they are discharged in the direction of arrow B. The display means 13 displays the dust collecting state and the ON / OFF state of the switch. When smoke is generated in the room, the smoke sensor 19 detects the smoke and sends a signal to the control device 20 to instruct the control device 20 to display the detection result on the display means 13 or to give an alarm. put out.

By the way, in the main body case 10, as shown in FIGS. 1 and 2, a sensor 21 for detecting a carbon oxide concentration or an oxygen concentration, an informing means 22, and a sensor for operating the informing means 22. And a control device 23. The sensor 21 is provided with a part thereof exposed from the surface of the main body case 10. In addition, the notification means 22 has, for example, a display unit that displays ventilation or the concentration of carbon oxide or oxygen, or an alarm device such as a buzzer, or both of them, and notifies both of them. An object is provided adjacent to the display means 13 in the window 10a.

Then, while the air purifier is in use, the sensor 21 detects the carbon oxide concentration or the oxygen concentration, and the sensor control device 23 determines that the carbon oxide concentration has risen above a certain value which has a bad effect on the human body. When this occurs, the sensor control device 23 activates the notification means 22 to display or give an alarm or both.

[0011]

[Effect of the device]

 Therefore, according to this invention, the sensor detects the carbon oxide concentration or the oxygen concentration in the indoor air, and the sensor control device activates the notification means to notify by the display or the alarm or both of them. It is possible to accurately know the contamination caused by the increase in the concentration of oxidized carbon in the indoor air while using the processing equipment. Therefore, it is possible to prevent the adverse effect on the human body due to the increase in the concentration of carbon dioxide in the air.
