Description

[Detailed description of the invention] (Field of industrial application) The present invention is a local heating and cooling device intended primarily for individuals indoors.

(Prior Art) Conventionally, when heating and cooling a room as a whole, the effects of heating and cooling differ depending on the location, resulting in a lot of wasted energy consumption.

In order to deal with this problem, there is a local heating and cooling system designed to blow cool or warm air only around the office desks, desks, and other workbenches indoors, such as Jikkosho. No. 5-8675 or Jitsukai Sho 49
It has been proposed as Publication No.-74903.

(Problem that Koan tries to solve) Among the above-mentioned conventional technologies, the former is simply equipped with a special type of ejection pipe that blows out clean air, and is not particularly intended for air conditioning or heating. In the latter case, a part of the desk is equipped with a cooler, a heater, and a heat exchanger, and the cold and warm air obtained from these is blown out toward the user at the top of the desk. The structure is complicated, and the management and handling of the equipment is troublesome.

(Means for solving the problem) The present invention eliminates the disadvantages of heating and cooling for individuals in the above-mentioned conventional systems, and makes local heating and cooling effective in both summer and winter. Air outlets opening toward the rear are provided at arbitrary heights on the upper and lower front surfaces of table boards, etc., and the secondary outlets are connected to the connecting pipe by switching valves, and the connecting pipe is connected to the wall or It is characterized by being connected to an installation port placed on the floor so that it communicates with the wind duct.

In the drawings of the embodiment, reference numeral 1 indicates an office desk, but other desks and work tables may be used.

Air outlets 22' opening toward the rear are provided on the upper and lower front surfaces of the table board 1' of the desk 1, respectively, and these are connected to the connecting pipe 3 by switching the switching valve 7. By inserting and connecting the lower end of the connecting port 5 arranged in advance on the wall or floor 4 of the room, the inside of the connecting pipe 3 is communicated with the air passage 6 arranged on the wall or the lower surface of the floor.

(Function) In the above device, warm air obtained from a separate air conditioning equipment is used in winter, and this air is circulated through the air passage 6 to the connecting pipe 3, and as shown in FIG. 3A, the switching valve 7 This is blown out from the outlet 2' on the lower surface of the table plate 1', and in the summer, this air is blown out from the upper surface of the table plate 1' by switching the switching valve 7, as shown in FIG. 3B, using cold air. The air is discharged from the air outlet 2, and when the air is interrupted from each air outlet, please refer to Figure 3C.
As shown in , the switching valve 7 is set to the neutral position and the air supply is stopped.

(Effect of the invention) According to the present invention, cold air is blown out from the outlet 2 on the top surface of the table board 1' in the summer, and the cold air is directed backward along the top surface of the table board 1' without immediately flowing downward; is table board 1'
Warm air is blown downward from the outlet 2' on the bottom surface, so the air immediately flows upward and is blown downward without escaping, so the user's surroundings can always be kept in a comfortable environment. It can be operated easily and at any time using the switching valve 7, and can be closed using the switching valve 7 when not in use.Furthermore, by providing the connection port 5, the desk 1 can be moved to any location at any time. It is convenient as a local heating and cooling facility in offices, factories, etc. because it can obtain cooled and warmed air, and it also saves a lot of energy because it does not have to cool or heat the entire room or wasteful spaces such as unoccupied spaces. It has an economical effect.
