Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to a chair equipped with an air conditioning function.

(Conventional technology) For heating and cooling in large spaces, a large air conditioner is installed in the mechanical room of a building, hot or cold air is blown out from outlets throughout the room through ceiling ducts, and then returned to the air conditioner via the air intake. The indoor environment is maintained by circulating hot or cold air.

Indoor heating and cooling temperatures can be determined by attaching a temperature setting device to the air conditioner, or setting a temperature setting and temperature sensing device in the room to be used, and heating and cooling the entire room while controlling the air conditioner. It's on.

(Problem to be solved by the invention) In the conventional method, the indoor temperature during heating and cooling is set at a constant temperature, and the air is discharged downward from the air outlet in the ceiling, but the indoor temperature is not necessarily constant. However, there are the following problems.

When heating, warm air stagnates in the upper layers of the room, resulting in a low-temperature region near the floor, making your feet cold.

During cooling, cold air stagnates in the lower layers of the room and can cause physical damage.

Since the indoor temperature is constant, it is not possible to adjust the temperature depending on individual differences.

Unable to respond to requests for heating and cooling due to individual differences outside of heating and cooling operation or outside of the heating and cooling season.

The present invention was proposed in view of the problems of the prior art described above, and its purpose is to create a temperature environment according to the preferences of the occupants in the room, and at the same time realize air conditioning that keeps the head cold and the feet warm. The point is to provide a chair with an air conditioning function.

(Means for Solving the Problems) In order to achieve the above object, the chair according to the present invention has heat absorbing and dissipating fins arranged in parallel to a thermal element having a Peltier effect, and a blower is disposed opposite to the heat absorbing and discharging fins. A cold/hot air generator disposed at the bottom of the back of the chair, a hot air outlet and a cold air outlet disposed at the lower bottom surface of the seat and the head of the backrest, respectively, and a heat absorption/dissipation fin in the cold/hot air generator. and a duct selectively connecting the hot air outlet and the cold air outlet.

(Function) Since the present invention is constructed as described above,
During cooling, the heat absorbing and dissipating fins attached to the thermal element having a Peltier effect in the cold/hot air generator are connected to the cold air outlet at the head of the backrest through a duct, and power is supplied from the DC power source of the heating element of the cold/hot air generator. cooling the heat absorption/dissipation fan side arranged in parallel to the isothermal element;
A blower installed opposite to the fin blows out cold air from the upper part of the chair through the cold air outlet.

In addition, during heating, the heat absorption/exhaust fan of the cold/hot air generator and the hot air outlet provided on the bottom surface of the seat are connected by a duct, and when the current flow of the heating element is reversed, the hot air outlet is connected to the hot air outlet. Warm air is blown out from the bottom of the chair.

(Example) The present invention will be described below with reference to the illustrated embodiments.

A is a chair with a warm air outlet 2 at the front end of the bottom of the seat 1.
is arranged, and cold air outlets 5 are provided on both sides of the head 4 of the backrest 3.
is installed.

A cold/hot air generator B is mounted on the lower back surface of the chair A via supporting legs or the like.

The cold/hot air generator B has heat absorption/dissipation fins 7 and 7' arranged in parallel before and after a thermal element 6 having a Peltier effect, and a DC power supply unit 8 for the thermal element 6.
A cross-flow fan 9 as a blower is provided opposite each of the fins 7 and 7'.

The heat absorbing fin 7 portion is connected to the hot air outlet 2 or the cold air outlet 5 via the duct C, and the heat absorbing fin 7' is connected to the exhaust outlet 1.
Connected to 0.

In the figure, 11 is an air supply port in the cold/hot air generator B.

The thermal element 6 has, for example, a p-type semiconductor and an n-type semiconductor coupled through an electrode, each of the fins 7 and 7' for heat exchange is attached to the electrode, and a DC power supply is connected to the electrode to generate a DC current. The junction portion of the semiconductor is cooled or heated by flowing the semiconductor.

Since the illustrated embodiment is configured as described above, during heating, the heat absorption/dissipation fin 7 side and the hot air outlet are connected by the duct C (see FIG. 1), and the heating element 6 in the cold/hot air generator B is connected to the hot air outlet. The said Finn 7
When a DC current is applied from the DC power supply unit 8 so that the side becomes the heat radiation side, the heat absorption and radiation fins 7 are heated, and the warm air supplied by the cross flow fan 9 flows under the seat part 1 of the chair A. The hot air is blown out from a hot air outlet 2 provided at the front of the bottom.

On the other hand, exhaust gas is discharged from the heat absorbing/radiating fin 7' side through the exhaust port 10.

Next, during cooling, the heat absorption/dissipation fin 7 side and the cold air outlet 5 are connected by a duct C (see Fig. 2).
When a direct current is passed through the thermal element 6 in the opposite direction to the previous direction, the heat absorbing and dissipating fins 7 are cooled, and cooling air is blown out from the cold air outlet 5 provided at the head 4 of the backrest 3 of the chair A. be done.

On the other hand, exhaust gas is discharged from the heat absorbing/radiating fin 7' side through the exhaust port 10.

(Effects of the invention) According to the invention, as described above, a warm air outlet is provided at the bottom of the seat of the chair, a cold air outlet is provided at the back of the chair, and a Peltier effect is provided at the bottom of the back of the chair. A heat absorption/dissipation fin is arranged in parallel to a thermal element having a heat absorption/dissipation fin, and a cold/hot air generator having an air blower is disposed opposite to the heat absorption/dissipation fin, and a side of the heat absorption/dissipation fin of the cold/hot air generator and the hot air outlet are arranged. and a cold air outlet are selectively connected with a duct, and by passing a direct current through the heating element, hot air is blown from the bottom of the seat of the chair and cooling air is blown from the head of the backrest. With this structure, heating and cooling can be freely controlled depending on individual differences, and a personal air conditioner that keeps the head cold and feet warm can be created using a chair.
