2. Description of the Related Art Heating and cooling of offices and the like has been performed for a long time, but in most cases, a large amount of cold air or hot air is blown out from a specific portion of the ceiling of a room or installed on the floor. Since the air is blown from the machine in a certain direction, there was a bias in the temperature and air flow in the room. Therefore, it was not always possible to create a comfortable environment for all people due to the position of each person's desk and the adaptability to heating and cooling. Also, after a certain time in the evening, the air conditioning and heating of all offices will stop, so the air conditioning and heating would have been completely lost during overtime work. In recent years, in order to eliminate such problems,
Panels have been proposed for heating and cooling around the desk of each person, but there is a risk that water pipes may be required to cause water leakage, or that only cooling or heating functions are useful only in specific seasons. was there.

[0003]

SUMMARY OF THE INVENTION The present invention solves the above-mentioned drawbacks of the prior art and is installed on the floor in the vicinity of the edge of a desk.
A compact structure that does not require water piping and can be used only by connecting to a power source, and it is an object to enable safe and clean cooling and heating around the desk for each person without worrying about water leakage.

It is blown out on the upper surface of 15.

On the other hand, the heating duct blower 8 installed above the heating duct D of the flow path Y in the second central portion sucks in the air flowing in from the upper suction port 4 at the upper end of the cooling duct R and heats it. The hot air switching damper 12 is sent downward in the duct D and is heated by passing through the high temperature side portion 6b of the thermoelectric element 6 having the Peltier effect, which is installed in the substantially central portion in the height direction of the heating duct D. After flowing into the lower portion of the first flow path X which has become ready for circulation by
The first flow path X is raised to be discharged upward from the warm air discharge port 3.

In the case of use for heating, first, the warm air switching damper 12 provided between the first duct X and the heating duct D of the second central passage Y is operated to operate the first duct. The high temperature side portion 6b of the thermoelectric element 6 of the heating duct D of the central flow passage Y and the heating outlet in a state where they cannot flow through the first flow passage X and the heating duct D of the second central flow passage Y. 9 and the cold air switching damper 13 provided in the third flow path Z are operated, and the flow direction of the air cooled through the low temperature side portion 6a of the thermoelectric element 6 is set to the upper end. Set to cooling outlet 10.
Also in this operation, when the operation / selection switch 14 provided on the surface of the first flow path X facing the desk 15 side in FIG. 1 is switched to the heating side, the switching dampers 12 and 13 are immediately switched to the above-described states. It is preferable that it is designed so that

When energization is started in this state, the temperature of the high temperature side portion 6b of the thermoelectric element 6 rises due to the Peltier effect,
The temperature of the low temperature side portion 6a of the thermoelectric element 6 drops. Then, the air that has flowed in from the lower intake port 5 of the room air located under the desk 15 of the heating duct D by the cooling duct blower 7 installed below the cooling duct R of the flow path Y in the second central portion The third flow path is sucked and sent upward in the cooling duct R, and is cooled by the low temperature side portion 6a of the thermoelectric element 6 having the Peltier effect, which is installed substantially in the center of the cooling duct R in the height direction. It flows into Z, and the flow direction is regulated by the cool air switching damper 13 provided in the third flow path Z toward the cool air discharge port 10 side at the upper end, and is discharged upward from the cool air discharge port 10. On the other hand, in the heating duct D, the air flowing in from the upper suction port 4 at the upper end of the cooling duct R is sucked in by the heating duct blower 8 installed above the heating duct D of the flow path Y in the second central portion. Is sent downwards,
The heating duct D is heated by the high temperature side portion 6b of the thermoelectric element 6 having the Peltier effect, which is installed substantially in the center of the heating duct D, and cannot be circulated under the first flow path X by the hot air switching damper 12. Since it is in such a state, it is blown out around the leg of the person sitting on the chair 17 from the heating outlet 9 to the position below the heating duct D and below the desk 15.

As described above in detail, the cooling / heating partition for parallel use of desks according to the present invention uses a thermoelectric element having the Peltier effect as a heat source, and the cavity in the partition is vertically separated by a drawing wall.
The partition is divided into two channels, and the central channel is divided into two in the thickness direction by a partition plate into a heating duct and a cooling duct, which are constructed in a wonderful manner as described above, resulting in a very compact structure. Although it has excellent cooling and heating capacity, the moving part is only two switching dampers, so the structure is simple and there are few failures, and as a power source to supply to the thermoelectric element with Peltier effect used as a heat source. Since the DC power source is used, it is possible to use a solar cell and save power consumption, and further, it is possible to keep the desk area safe and clean.

When the above two switching dampers are used for either cooling or heating, the temperature that has passed through the heating duct of the second central passage is controlled by the operation / selection switch. If the structure is such that the flow path of the wind and the cold air that has passed through the cooling duct of the second central flow path are switched at the same time, the operation is easy, and the hot air discharge port, the upper suction port, and the lower suction port are easy to operate. If filters are installed at each of the mouth, the cold air outlet, and the cooling air outlet, it is effective for cleaning the air in the environment. Industrial applicability of the side-by-side cooling / heating partition according to the present invention having such various effects is extremely great.
