Abstract

PROBLEM TO BE SOLVED: To activate an air cleaner, only when a table is attended by a user. SOLUTION: This smoking table is provided with an air cleaner 6, 7, a human body detecting sensor 1, and a control member which makes the air cleaners operate by the human body detecting output from the human body detecting sensor 1. The human body detecting area of the human body detecting sensor 1 faces downward the table. Therefore, the table can detect only a table user and make the air cleaners operate.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a smoking table for preventing the diffusion of tobacco smoke and purifying the air.

[0002]

2. Description of the Related Art There has been provided a smoking table which has a built-in air purifier and which uses a table to prevent the diffusion of cigarette smoke and purify the air. In this smoking table, a human body detecting means is provided. In addition, there is one in which an air purifier is operated according to human body detection.

[0003]

In the case of operating the air purifier by detecting a human body, it is not necessary to turn on the switch, and it is possible to surely prevent the diffusion of smoke. The air purifier is activated even though people who pass by far away from the table, that is, people who do not intend to smoke at the table, respond even if no one is smoking Sometimes occurred.

[0004] The present invention has been made in view of such a point, and an object of the present invention is to provide a smoking table in which an air purifier operates only when a table user is present.

[0005]

SUMMARY OF THE INVENTION The present invention provides an air purifier and a human body detection sensor.
A smoking table provided with a control member for operating an air purifier with a human body detection output from a human body detection sensor is characterized in that a human body detection area of the human body detection sensor is directed to a lower side of the table.

The air purifier can be operated by detecting only a table user.

If the human body detection sensors are provided on the diagonal line of the table, a table user can be reliably detected with a small number of human body detection sensors.

[0008] By making the orientation of the human body detection sensor variable, it is possible to eliminate an area where a human body cannot be detected near the table.

By providing a cover for covering the human body detection sensor, the human body can be detected while protecting the human body detection sensor.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail below with reference to an example of an embodiment. The smoking table shown in FIG. 1 has a suction opening 4 covered with a wire mesh 3 at the center of the upper surface of a top plate 10 thereof. Is provided with a duct 5 connected to the suction port 4 inside the main body, and an air purifier including an air filter 6 and a fan 7 is arranged in a path of the duct 5, and the air sucked from the suction port 4 is provided. Is discharged from the lower outlet 8 after passing through the air filter 6.

The smoking table is provided with the human body detection sensor 1 and the control circuit block 9 which receives the human body detection output of the human body detection sensor 1 and operates the fan 7. The detection sensor 1 is mounted on the lower surface of the peripheral portion of the top panel 10, and the human body detection area A is set downward.

The control circuit block 9 also includes a timer circuit and a power supply circuit, and the operation flow is shown in FIG.
Human body detection sensor 1 when a person approaches a smoking table
Is detected, the ON output of the control circuit block 9
Starts the count by activating the timer,
By operating the fan 7 (air purifier), the smoke of the tobacco is suctioned from the suction port 4 and passed through the air filter 6 to be cleaned.

The above timer is reset if the human body detection sensor 1 operates within the delay time,
If the human body detection sensor 1 is not turned on and the time count ends, the power is turned off and the fan 7 is stopped.

If the detection area A of the human body detection sensor 1 is directed downward toward the lower side of the table, the installation location does not have to be the lower surface of the top plate section 10, and as shown in FIG. It may be the side surface of the (leg). In this case, since the top panel 10 can be separated, it can be disassembled and transported.

As shown in FIG. 3, the attachment 12 of the human body detection sensor 1 can be used to change the direction of the human body detection sensor 1, that is, to shift or widen the detection area A. By doing so, it is possible to eliminate an area where a human body cannot be detected near the table.

Further, as shown in FIG. 4, when the human body detecting sensors 1 are arranged on a diagonal line of the table, even in the case where the duct 5 is provided at the center as shown in the drawing, two human body detecting sensors 1 and 1 are provided. Accordingly, human body detection can be performed in the entire area below the table.

FIG. 5 shows a case where a cover 2 for covering the outer peripheral portion of the human body detection sensor 1 is provided. By covering the cover 2, the human body detection sensor 1 can be protected.

[0018]

As described above, according to the present invention, there is provided a smoking table including a human body detection sensor and a control member for operating an air purifier with the human body detection output from the human body detection sensor. Because the detection area is set below the table, only the table user can be detected and the air purifier can be activated,
It is possible to eliminate a situation in which the air purifier is activated simply by passing a person around the table, and it is possible to eliminate wasteful consumption of power due to a malfunction.

By providing the human body detection sensors on the diagonal line of the table, a table user can be reliably detected with a small number of human body detection sensors.

Further, by making the direction of the human body detection sensor variable, it is possible to eliminate an area where a human body cannot be detected near the table.

Further, by providing a cover for covering the human body detection sensor, the human body can be detected while protecting the human body detection sensor.
