Description

Description: TECHNICAL FIELD The present invention relates to a floor panel built-in air conditioner and an air conditioner applied to air conditioning of a small space such as office.

(Prior Art) Conventional office air conditioning uses either hot or cold air from a ceiling outlet, cool or hot air from an air conditioner installed indoors, or an air conditioning duct under the floor, or an underfloor air chamber. The hot and cold air is blown out from the air outlet provided on the floor.

(Problems to be Solved by the Invention) In the conventional cooling and heating method, the temperature of the entire room is planned to be uniform, and it is common to control the temperature in such a manner that it suits individual tastes and physical conditions of the day. It is difficult to partially create a warm environment.

If the air conditioner is too effective or the feet are cold even during heating, an electric heater or the like has been conventionally used, but a space for placing the heater was required.

On the other hand, in general, it is not possible to deal with the case where it is desired to cool only the area around the individual.

The present invention has been proposed in view of such a situation, and the intended place thereof does not require an extra space,
An object of the present invention is to provide a floor panel built-in type air conditioner and an air conditioner in which a thermal environment around an individual can be freely selected according to individual preference.

(Means for Solving the Problem) In order to achieve the above-mentioned object, a floor panel built-in type air conditioner according to the present invention includes a floor panel type casing including an air inlet, an outlet and an outlet, respectively. A thermoelectric conversion element having a Peltier effect disposed in the same casing, and heat absorption / dissipation fins disposed both above and below the element, a DC power source for the thermoelectric conversion element, and an air supply fan for the thermoelectric conversion element. Further, the air conditioner according to the present invention comprises one of the floor panels installed on the floor surface of the building from the floor panel built-in type air conditioner, and from the discharge port of the casing in the air conditioner. The discharged air is configured to flow through the lower space of the floor panel adjacent to the casing.

(Operation) Since the air conditioner according to the present invention is configured as described above, when the DC power is supplied from the DC power source to the thermoelectric conversion element, and when the supply fan is operated, suction is performed from the air suction port of the casing. The entrapped air is cooled on the heat absorption side and heated on the heat radiation side while passing through the heat absorption / radiation fins.

In the case of cooling, a direct current is caused to flow so that the upper side of the thermoelectric conversion element is on the heat absorbing side, and is taken out as cold air from the air outlet provided in the casing.

On the other hand, the air passing under the thermoelectric conversion element is heated and blown from the outlet of the casing to the lower part of the adjacent floor panel.

When heating is performed next, when the direct current to the thermoelectric conversion element is reversed, the upper side of the element becomes the heat radiation side and hot air is taken out. At this time, the lower side of the element becomes a heat absorption side, and cold air is discharged from the outlet of the casing.

According to a second aspect of the present invention, one of the floor panels is composed of the floor panel built-in type air conditioner, and the air discharged from the outlet of the casing when heated and cooled by the air conditioner is adjacent to the casing. It is intended to flow through the space below the floor panel.

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

(1) is a floor panel type casing having an air inlet (2) and an air outlet (3) on the upper surface, and an air outlet (4) on the side surface.

(5) is a thermoelectric conversion element having a Peltier effect disposed in the casing (1), and comb-shaped heat radiation fins (6) (6 ') so that heat can be efficiently converted into upper and lower surfaces thereof.
Are provided, and a heat source (A) is configured.

An air supply fan (7) for the heat source, a DC power supply (8) for the thermoelectric conversion element, and a booster fan (9) described later are further provided in the casing (1).

In the figure, (10) is a heat insulating material.

The air conditioner configured as described above is disposed on the floor surface, and when the direct current is supplied from the direct current power source (8) to the thermoelectric conversion element (5) and the supply fan (7) is operated, the casing (1 ) Is sucked into the casing (1) through the air suction port (2), and the suction air is cooled on the heat absorption side and passes on the heat radiation side while passing through the heat radiation fins (6) (6 '). Be heated.

In the case of cooling, a direct current is made to flow so that the upper side of the thermoelectric conversion element (5) is endothermic, the intake air is cooled by the upper heat absorption and release fins (6), and taken out as cold air from the air outlet (3), The local space in the room where the air conditioner is installed is cooled.

On the other hand, the suction air passing through the lower heat radiation and discharge fins (6 ') is heated and blown out from the discharge port (4) to the lower part of the adjacent floor panel.

At this time, if a sufficient air volume cannot be secured, a booster fan (9) arranged near the discharge port (4) is required.

Further, when heating is performed, if the direct current to the thermoelectric conversion element (5) is reversed, the upper heat absorbing and radiating fins (6) become the heat radiating side and hot air is taken out. At this time, the lower heat-radiating fins (6 ') are on the heat-absorbing side, and cool air is discharged from the discharge port (4).

FIG. 5 shows an air conditioner in which the air conditioner is incorporated in a room such as an office. One floor panel built-in air conditioner (C) under the desk (B) is used as the air conditioner. By operating the machine (C), the air under the desk (B) is sucked into the casing (1) through the suction port (2), and is blown into the space below the desk (B) through the air outlet (3) depending on the purpose. The cold or hot air is blown out to heat and cool the local space around the desk (B).

At this time, the air discharged from the discharge port (4) of the casing (1) flows through the space below the floor panel (D) adjacent to the air conditioner (C), and the adjacent floor panels (D).
If there is a gap between them, it will flow out little by little from the gap. If there is no gap between the floor panels (D), it is necessary to provide the floor panel (D) with a ventilation port (E).

(Effect of the invention) As described above, the floor panel built-in type air conditioner according to the present invention,
A floor panel type casing equipped with an air inlet, an outlet, and an outlet, a thermoelectric conversion element having a Peltier effect, and heat-radiating fins and DC power supplies for the thermoelectric conversion element, which are arranged on the upper and lower surfaces of the element. By incorporating an air supply fan for the thermoelectric conversion element in the above, it is possible to easily switch between cooling and heating simply by reversing the plus and minus of the direct current sent to the thermoelectric conversion element, and each individual has his or her own preference. Sometimes the work space can be cooled or heated.

In addition, since it cools and heats a small space, it has little effect on the surroundings and is suitable for personal use or for office equipment corners.

According to the invention of claim 2, one of the floor panels arranged on the floor surface of the building is constituted by the above-mentioned floor panel built-in air conditioner,
The air discharged from the casing outlet of the air conditioner constitutes an air conditioner that flows through the space under the adjacent floor panel. By putting the air conditioner inside the floor panel, the work space is air-conditioned. The space is not narrowed by the device, and the underfloor space for the exhaust air is smaller than that in the case where a cool / hot air duct or a chamber is provided under the floor.
