(Prior Art) An air conditioner in an office is generally a ceiling blowout, ceiling suction or wall suction type air conditioning system for the entire room.

(Problems to be solved by the invention) Therefore, in the conventional air conditioner, cold air stays on the floor surface,
In both summer and winter, there is a phenomenon that the feet get cold, and in addition, the temperature distribution is often uneven in the plane due to the arrangement of furniture.

Further, even if the entire room can be made to have a uniform thermal environment, it will not be an environment in which everyone in the room is satisfied because of individual differences.

The present invention has been proposed in view of the above problems of the prior art, and an object thereof is to provide an auxiliary air conditioner capable of eliminating a vertical temperature distribution in a room and creating a thermal environment desired by an individual. The point is to provide a local air conditioner.

(Means for Solving the Problems) In order to achieve the above-mentioned object, a local air conditioner according to the present invention supplies a space in a panel constituting a desk by a partition wall including a thermoelectric element having a Peltier effect. It is divided into a side space and a discharge side space, and a supply side fin and a supply side fan that are in contact with the thermoelectric element are built in the supply side space, and a discharge side fin that is in contact with the thermoelectric element is included in the discharge side space. And a suction port and a pair of upper and lower outlets are arranged in the supply side space, and a suction port and a discharge port are arranged in the discharge side space.

In order to further improve the cooling and heating effect, the supply side fins and the discharge side fins are arranged orthogonal to each other, and the thermoelectric elements are arranged in a staggered manner along the discharge side fins,
The thermoelectric elements in each row may be arranged in series along the supply fins.

(Operation) Since the present invention is configured as described above, a thermoelectric element having a Peltier effect provided on a partition wall that divides a space in a panel forming a desk into a supply side space and a discharge side space is provided. When energized by a DC power source, the supply side fan and the discharge side fan built in each space are operated, and air is sucked into the space through the suction port, the air sucked into the supply side space is It is cooled or heated by the supply side fins and blown out from the blowout port to form a local thermal environment.

Further, among the upper and lower outlets in the supply side space during cooling, cool air is blown out from the upper outlet, and warm air is blown from the lower outlet during heating to form an environment of head cold foot heat.

On the other hand, the air sucked into the discharge side space is heated or cooled by the discharge side fins and is discharged from the air outlet.

Further, the heating / cooling is switched by switching +/- of the DC power source to the thermoelectric element.

Further, the supply side fins and the discharge side fins are arranged orthogonally, the thermoelectric elements are arranged in a staggered manner along the discharge side fins, and the thermoelectric elements in each row are arranged in series along the supply side fins. Therefore, the supply-side air passing through the supply-side fins sequentially passes over the thermoelectric elements arranged in series along the same fins and is gradually cooled or heated.

On the other hand, when the exhaust side air passes through the exhaust side fins, it passes over one thermoelectric element, then passes between adjacent thermoelectric elements in the next row, and is heated as compared with the supply side air, Alternatively, the degree of cooling is reduced, and the temperature increase or temperature decrease of the supply side cooling air or the heating air due to the discharge side air is prevented.

(Examples) The present invention will be described below with reference to illustrated examples.

(A) is a partition type office desk, which is a partition wall (3) comprising a thermoelectric element (2) having a Peltier effect, which is made of a heat insulating material in the center of the inside of a hollow panel (1) constituting the side wall thereof. ) Is provided and is partitioned by the partition wall (3) into a supply side space (a) and a discharge side space (b).

A supply side fan (4) is built in the supply side space (a), a supply side fin (5) in contact with one surface of the thermoelectric element (2) is arranged, and a supply side air suction port is provided at a lower portion. (6) is provided, and an upper air outlet (7a) and a lower air outlet (7b) for supply-side air are provided in the upper portion.

On the other hand, the discharge side fin (9) is built in the discharge side space (b), and the discharge side fin (9) that is in contact with the thermoelectric element (2) and is orthogonal to the supply side fin (5) is arranged, A discharge side suction port (10) is arranged in the lower part of one side part, and a discharge side blowout port (11) is arranged in the top part of the other side part.

Thus, the thermoelectric element (2) is connected to a DC power source,
As shown in the figure, the thermoelectric elements (2) in each row are arranged in a zigzag pattern along the discharge side fins, and the thermoelectric elements (2) are arranged in the supply side fins (5).
Are arranged at predetermined intervals along the longitudinal direction, that is, along the direction in which the supply-side air flows.

Since the illustrated embodiment is configured as described above, when a direct current is passed through the thermoelectric element (2) and at the same time the supply side fan (4) and the discharge side fan (8) are driven, the suction port (6 ), The supply side air sucked into the supply side space (a) is gradually cooled or heated while passing through the supply side fin (5), and is sucked out from the outlets (7a) (7b). A local thermal environment can be obtained.

On the other hand, the discharge side air sucked into the suction side space (b) through the discharge side suction port (10) is discharged through the blowout port (11).

The blowing of hot air and cold air can be switched by changing + and-of the DC power source for the thermoelectric element (2).

Next, a usage example of the illustrated apparatus will be described.

At the time of cooling, the set temperature for air conditioning in the entire room is set slightly higher. In this case, a comfortable thermal environment can be obtained without using this device for persons who prefer a little high temperature, such as elderly people and women.

In this setting, people who feel that it is hot use this device.

Therefore, during cooling, cold air tends to stay near the floor surface. In such a case, the lower outlet (7b) in the supply side space (a) is opened and closed by being mounted on the same outlet (7b). It is closed by a wing device so that cold air is blown out from the upper outlet (7a). It is comfortable to apply cold air to the upper body, especially the head. At this time, the cold wind is at a slight wind speed, so that it is not uncomfortable.

The air outlet may be a swinging device that automatically changes the wind direction.

Next, during heating, the entire room is conditioned at a slightly lower temperature, and those who prefer a higher temperature operate this device.

Generally, the lower half of the body often feels colder, so by closing the upper outlet (7a) and blowing warm air from the lower outlet (7b), the lower part of the top plate (1 ') of the office desk (A) A warm environment is provided, and a comfortable environment of head cold foot heat can be obtained.

In either case, the discharged air is blown out to the upper part of the room by a slightly high blowing speed, and is sucked from the suction port of the entire air conditioning to process the load.

Thus, in the above-mentioned embodiment, as shown in FIG. 5, the thermoelectric elements (2) are arranged in a staggered manner along the discharge side fins,
Since the thermoelectric elements (2) in each row are arranged in series along the supply side fins (5) at predetermined intervals, and the discharge side fins (9) are arranged so as to be orthogonal to the supply side fins (5). ,
During cooling, the supply-side air passing through the supply-side fins (5) is
It passes through the heat absorbing side of the plurality of thermoelectric elements (2) arranged in series and is gradually cooled.

At this time, the thermoelectric element (2) in which the discharge side air is arranged in series
Since the surface facing the discharge side space of the thermoelectric element becomes the heat radiation side when passing through above, the temperature of the discharge side air gradually rises, and if the temperature of the exhaust side is high, the cooling side of the thermoelectric element (2) The temperature also rises and it becomes impossible to lower the temperature of the supply side cool air.

However, according to the above-mentioned embodiment, since the thermoelectric elements (2) are arranged in a staggered pattern, when the air on the discharge side passes through the fins (9) on the discharge side, it passes over one thermoelectric element (2). After that, it passes through the middle of the adjacent thermoelectric elements (2) in the next row, and the rise in temperature of the exhaust side air is suppressed.
The temperature rise of the cold air on the supply side is prevented.

Due to the same reason as described above, the effect of raising the temperature of the hot air can be obtained even when + and-of the DC power source to the thermoelectric element (2) are switched and hot air is blown from the supply side space.

Although six thermoelectric elements (2) are used in the above embodiment, the number of the thermoelectric elements (2) is determined by the required capacity of the apparatus.

(Effects of the Invention) As described above, the present invention provides, in the space in the panel forming the desk installed in the office of the office, in the supply side space partitioned by the partition wall including the thermoelectric element having the Peltier effect. , A supply side fin and a supply side fan are built in, a discharge side space is provided with a discharge side fin and a discharge side fan, and a suction port and a blowout port are provided in the supply side space and the discharge side space, respectively. As a result, local cooling and heating can be performed according to personal preference without using cold / hot water pipes, refrigerant pipes, and the like, and uneven distribution of vertical temperature in the room can be eliminated.

Further, since the thermoelectric element having the Peltier effect is used, the switching operation between heating and cooling can be easily performed.

Furthermore, since the outlets in the supply side space are composed of upper and lower outlets, an ideal warm environment for head cold foot heat can be obtained.

In the invention of claim 2, the supply side fins and the discharge side fins are orthogonal to each other, the thermoelectric elements are arranged in a staggered manner along the discharge side fins, and the thermoelectric elements in each row are arranged in series along the supply side fins. By disposing the thermoelectric element, the heat absorption / exhaust effect by the thermoelectric element is improved, and the local cooling / heating effect is improved.
