DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a desk equipped with an air cleaning unit and used in an office or the like.

[Conventional technology]

BACKGROUND ART Conventionally, in an office or the like, an air purifying unit is placed near a partition of a desk, and an inlet and an outlet are formed in the partition.

[Problem to be solved by the invention]

However, the structure relies only on the suction force from the inlet to introduce air contaminated with cigarette smoke, etc. into the inlet, and the suction force cannot be increased too much, so the cigarette smoke on the desk etc. cannot be aspirated immediately. Therefore, cigarette smoke, etc. rises and is not sucked into the suction port. Therefore, the collection efficiency is poor.

In addition, since the air purification unit is placed around the desk,
There was a problem that the area around the desk became complicated.

An object of the present invention is to provide a desk that has good efficiency in collecting dirty air and that can neatly accommodate the area around the desk.

[Means for Solving the Problems] The desk of the present invention has partitions erected on at least two of the four sides surrounding the top plate except for the front side, a ventilation unit is housed in the side partition, and other An air cleaning unit is housed in a partition. The suction port of the air purifying unit is located further back than the discharge port of the blower unit.The front side refers to the part toward which a person sits.

[Effect]

According to the configuration of this invention, the dirty air on the desk, such as cigarette smoke exhaled by the person in front of the desk, is carried by the airflow blown from the ventilation opening of the side partition, and is carried to the other partitions. It is sucked into the air purification unit's suction port. The sucked air is purified by an air cleaning unit and then discharged.

Since the suction port is located further back than the discharge port, the air is blown toward the back, and smoke that drifts around the mouth can also be carried on the blown airflow.

〔Example〕

A first embodiment of the present invention will be described based on FIGS. 1 to 6. Partitions 2 to 4 are erected on both sides and the back side of the four sides around the top plate 1a of the desk 1. A blower unit 5 is housed in the front side of the partition 2 on the right side of the figure, and an air purifying unit 6 is housed in the back side of the partition 3 on the left side. Air outlet 8 of air blower unit 5

In this way, since dirty air is collected by both blowing and suction, the collection efficiency is high, and the cigarette smoke discharged on the desk 1 is well sucked in through the suction port 9 before it rises. be able to. The suction port 9 is located further back than the air outlet 8, so even if the smoke that has been discharged is floating around the mouth, the air inlet 8
It can be placed on the air blower.

In addition, the suction lower of the blower unit 5 is partitioned into the partition 20.
Since it is provided in the front part, when an ashtray is placed near the suction lower and a cigarette is placed on it, the sidestream smoke of the cigarette is sucked into the suction lower and sent from the blower unit 5 to the air cleaning unit 6. Therefore, sidestream smoke is prevented from escaping upward.

Since partitions 2 and 3 are provided on both the left and right sides of the desk 1, cigarette smoke is prevented from escaping to the neighbor, improving collection efficiency. In addition, since the partition 4 is located on the back surface of the desk 1, the air blowing lower has a guiding action and the collection efficiency is further improved.

Although the discharge port 10 of the air purifying unit 6 is provided on the top surface, the position of the discharge port 10 is separated from the suction port 9, and some of the smoke that approaches the suction port 9 is drawn into the discharge airflow from the discharge port 10.
