BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a desk on which office automation equipment is placed, which is equipped with an air conditioning function to keep the feet of the desk cool.

0002

BACKGROUND OF THE INVENTION The popularity of office automation equipment has been rapid due to its wide range of advantages, including improved office efficiency, lower paper consumption, and more efficient use of office space. These devices are equipped with heat exhaust fans to cool the electronic components inside. Since this waste heat hitting the worker's face increases the power of air conditioning, there are partitions and the like that are equipped with heat exhaust paths that take the heat exhaust path into consideration. In addition, in order to warm the feet of operators who operate office automation equipment for long periods of time, the backboard of the desk was equipped with a hot air supply duct to blow hot air to the feet of operators. From this point of view, floor-blowing air conditioners are also becoming popular.

[Problems to be Solved by the Invention] However, there seems to have been no consideration for returning waste heat from office automation equipment to the operator's feet to prevent the feet from getting cold. There was little air convection under the desk, especially when a desk with a backboard or sideboard was installed in an area surrounded by a partition. For this reason, there was almost no heat transfer, and cold air tended to be trapped during both cooling and heating operations. Even though the upper body was in a perfectly air-conditioned environment, only the lower body felt cold, and by concentrating and sitting for long periods of time, the lower body seemed to become even colder without realizing it.

The present invention has been made in view of the above circumstances, and its purpose is to provide a desk equipped with an air conditioner that can effectively utilize waste heat from office automation equipment and prevent the operator's feet from getting cold. There is a particular thing.

[0005]

[Means for Solving the Problems] In order to achieve the above object, the desk equipped with an air conditioning function of the present invention is a desk on which office automation equipment is placed, and a ventilation duct is installed around the desk to flow air from the upper part of the room to the lower part. The exhaust heat from the office automation equipment was sent to the ventilation duct, and an outlet was provided below the ventilation duct to blow out the exhaust heat at the foot of the desk. In order to encourage convection to flow air from the upper part of the room to the feet of the desk, the intake port of the ventilation duct is installed at the upper part of the room, or the top of the ventilation duct is connected to an air supply duct that has an opening at the top of the room.
The blower was installed below the suction port.

[0006]

[Operation] The waste heat from the office automation equipment is not directly released into the room and diffused, but is released to the foot of the desk according to the direction of the ventilation duct. Warm air stays near the ceiling of the room, so it is drawn into the ventilation duct through the inlet installed at the top of the room or the opening on the top of the room, mixed with the waste heat from the office automation equipment, and distributed to the feet of the desk. It is emitting. If the blower is placed above the inlet, the air taken in through the opening in the top of the room will exit through the inlet, so the blower should be placed below the inlet to direct the heat that accumulates during heating to the foot of the desk.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention will now be described in detail with reference to the drawings. An example is shown in FIG.
The top board of the machine is structured into two levels, top and bottom, with the printer placed on the top top board 3, and the keyboard, CRT, computer terminal, word processor, etc. placed on the bottom top board 3a. . The back plate 2 of the desk 1 may or may not also serve as a partition, but it is raised to near the ceiling 7 of the room 5, and the area above the top plates 3 and 3a is equipped with the above-mentioned office automation equipment. Intake ports 9 connected to the exhaust ports of each office automation device are opened to take in exhaust air. A ventilation duct 11 that wraps around the intake port 9 and extends vertically is integrally formed with the back plate 2 and is vertically elongated from the floor 13 to the ceiling 7, and an air outlet 15 is provided near the floor 13 of the duct 11. Further, the top of the duct 11 is connected to a heat collection path 19 installed under the ceiling so as to continuously surround the openings 17 provided intermittently in the ceiling 7 and guide the top of the duct 11. Furthermore, a suction port 21 is provided in the upper part of the back plate 2 so as to communicate with the ventilation duct 11, and an opening/closing damper 23 is provided between the suction port 21 and the heat collection path 19. A blower 25 is installed in the ventilation duct 11 at a position below the top plate 3a so as to blow out air to the outlet 21.

During heating in winter, in order to introduce hot air accumulated near the ceiling of the room 5 into the ventilation duct 11, the damper 23 is opened, and warm air containing exhaust heat from the office automation equipment is sent from the air outlet 15 to the blower 25. warm air is blown out at the feet of desk 1. When the blower 25 is started, the exhaust heat from the office automation equipment flows into the ventilation duct 11 from the suction port 9, and the exhaust heat is sent to the operator's feet without interfering with the cooling power of the office automation equipment. The same applies to summer cooling, but if the air temperature near the ceiling 7 is lower than the exhaust heat from the office automation equipment, it is better to close the damper 23. Therefore, depending on the situation, it may be better to close the suction port 21 as well. Further, the upper end of the ventilation duct 11 remains open to the upper part of the room 5, and it functions satisfactorily without providing the suction port 21, the heat collection path 19, etc., and can be said to be advantageous in terms of simplicity. However, it is certainly more effective to provide a heat collection path 19 and connect the ventilation duct 11 to the heat collection path 19 in a heating room of the ceiling type. In this way, the desk 1 is constructed which can keep the operator's feet warm at all times using the waste heat from the office automation equipment.

[0009]

[Effects of the Invention] As explained in detail above, the desk equipped with an air conditioning function of the present invention is provided with a ventilation duct around the desk that flows air from the upper part of the room to the lower part of the room, and the duct is connected to the exhaust heat of the office automation equipment. The exhaust heat is discharged to the feet of the desk through the outlet below, so even when working at a desk for long periods of time, the air-conditioned environment at the feet is higher than the room temperature, making it difficult for workers to work. It has the effect of preventing your feet from getting cold. Also,
If the air near the top of the room is taken into the ventilation duct through the inlet or the opening on the top of the room, it will compensate for the lack of exhaust heat from office automation equipment and create conditioned air that can reliably warm the feet of the desk. be.
