Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a cold / hot air switching panel suitable for forming a wall of a general house or a wall of a bathroom.

<Prior Art and Problems Thereof> A large number of so-called cooling / heating device walls, in which a heating device and a cooling device are provided in a wall panel and hot air or cold air is blown into a room by a fan, have already been proposed. All of these device walls are for hot air or cold air,
Moreover, since the heating device and the cooling device are incorporated in the panel, the thickness of the panel itself is inevitably increased. As a result, in addition to the time and labor required for assembling and constructing the panel, various problems such as narrowing the living room space of the building were presented.

<Means for Solving the Problems> The present invention has been made to solve the above problems. A fan is arranged in the approximate center of the plane of a rectangular flat panel.
The air blower around the inside of the panel is formed as an air passage, and at each of the four corners in the panel of this air passage, a heat surface that can switch between heat dissipation and heat absorption by using the Peltier effect is provided, and this heat surface is marked. By changing the polarity of the DC power source that fires, each heat surface can be changed to a heat radiation surface or a heat absorption surface, and the air blown from the blower to the room can be changed from cold air to warm air or from warm air to cold air. is there.

<Operation> That is, the cold / warm air switching panel of the present invention has a thin and lightweight panel by providing a hot surface capable of switching between heat absorption and heat dissipation by utilizing the Peltier effect in the air passage in the surface of the panel. Be promoted. Also, by switching the DC power supply applied to the hot surface, the heat absorbing effect and the heat radiating effect can be varied on the hot surface, so it is possible to switch the blowing air from the blower from cold air to warm air or from warm air to cold air. Become.

<Implementation Cooling> The cold / hot air switching panel of the present invention will be described in detail below with reference to the drawings.

FIG. 1 is an explanatory schematic diagram of the cold / hot air switching panel 1.
The cold / hot air switching panel 1 has a panel shape for a structural body used to construct a general house, that is, a so-called rectangular flat plate shape. As the frame of the panel, a wooden frame material or a lightweight steel material is usually used. In this panel, the blower 2 is arranged in the approximate center of the plane, and the periphery thereof is formed as an air passage 11. Then, at the four corners of the air passage 11, heat absorbing / dissipating devices 3A, 3B, 3C, 3D are incorporated respectively. These heat absorbing / radiating device 3
(3A, 3B, 3C, 3D) uses the Peltier effect.
As shown in the figure, a semiconductor Peltier element 31 made of a bismuth tellurium (Bi ₂ Te ₃ ) compound or the like is sandwiched between a pair of hot surfaces 32 and 33, and the hot surfaces 32 and 33 are exposed to the air passage 11. It The DC power supply circuit E is connected to either one of the Peltier elements 31. When a predetermined voltage, for example, about 10 V is applied to the Peltier element 31 by the DC power supply circuit E, the Peltier effect is exhibited in which the heat surface 32 has a heat radiating action and the other heat surface 33 has a heat absorbing action. . Normally, the heat-absorbing / radiating device 3 is sealed by a resin mold with the heat surfaces 32 and 33 exposed to the outside and is formed in a small size, and therefore has a high moisture resistance. Further, since it is driven by the DC power supply circuit E, unlike the conventional cooling and heating device, it does not require a medium such as liquid or gas, and the operation and maintenance are extremely simple. Also, there is little noise and vibration. Therefore, even if it is incorporated in the panel as described above, the panel itself hardly emits noise and hardly vibrates, which makes it suitable as a building frame.

Next, based on FIG. 1, the cold / hot air switching panel 1
The temperature switching action will be described.

First, the DC power supply circuit E applies a predetermined voltage to each of the Peltier elements 31, 31 ... Of the heat-absorbing / radiating devices 3A, 3B ... (See FIG. 2). Then, the Peltier effect is exerted, and the heat radiating action works in the cross section 32 of each of the heat absorbing / radiating devices 3A, 3B. Further, an endothermic action works on the other hot surface 33. Therefore, when the outside air O is taken into the panel and introduced from the hot surface 33 side, the heat is absorbed, and the outside air O is further blown to the hot surface 32 through the air passage 11. In addition, suction ports 12 and 13 are formed in the vicinity of the heating surface 32 in a communicating state, and the indoor air I sucked from the suction ports 12 and 13 is heated by the heating surface 32 and blower 2 Is released to the inside of the room via. This warms the room.

On the other hand, if the polarity of the DC power supply in the DC power supply circuit E is switched in the opposite manner by a changeover switch (not shown), the action of the Peltier element 31 is reversed, and the heat absorbing action is exerted on the heat surface 32. The hot surface 33 then radiates heat. Therefore, in each of the heat dissipation / radiation devices 3 (3A, 3B, 3C, 3D), the heat absorption function works on the heat surface 32,
The indoor air I sucked from the suction ports 12 and 13 absorbs heat and is blown out into the room as cool air through the blower 2.

As described above, the cold / hot air switching panel 1 works as a cold air panel.

In the above description, the upper surface material of the cold / warm air switching panel 1 is not added, but, for example, a wood plywood may be attached, or a concrete thin plate or a plate material made of a synthetic resin material may be attached. Furthermore, if a far-infrared ray generating panel or the like is attached to the upper surface of the heat absorbing / radiating device as needed, the far-infrared ray generating panel will be heated to generate effective infrared rays. It can be used as it is as a wall panel that composes the above.

This far-infrared ray generation panel has a special alumite coating formed on the surface of, for example, an Al-1.5% Fe alloy, and when heated to 50 to 60 ° C. by the heat radiating portion 32 of the heat absorbing / radiating device 3, a far infrared ray of about 8 to 10 μm. It generates infrared rays.

Therefore, the sauna chamber and the drying chamber can be easily formed by the synergistic heat effect of the radiant heat and the warm air.

<Effect of the device> As described above, the cold / warm air panel of the present invention drives the air-absorbing / heat-dissipating device because the air-absorbing / heat-dissipating device utilizing the Peltier effect is incorporated in the in-plane air passage of the panel together with the fan With the length that switches the polarity of the DC power supply, the blowing air can be changed from warm air to cold air or from cold air to warm air, making it extremely convenient to use. In addition, since the heat sink / radiator can be sealed and miniaturized, the entire panel can be made thin, and since no medium such as liquid or gas is used, maintenance is easy and there is little noise or vibration. It is also suitable as a wall panel.
