Description

[Detailed description of the device]

[0001]

[Industrial applications]

 This invention relates to a heating chair in which a heating device is provided on the chair.

[0002]

[Prior Art]

 Conventionally, when a person sits in a chair and studies or works at a desk in the cold winter season, of course, there is a heating device in the room, but the heating device alone did not warm the feet and waist. For this reason, a separate heating device has been placed under the feet or on the waist to warm it.

However, in this case, a person often forgets to switch off the heating device when he / she is away from the chair, and there is a risk of causing a fire if the electricity is wasted or if the switch is left off for a long time. there were.

[0004]

[Problems to be solved by the device]

 As mentioned above, according to the conventional method, people often forget to turn off the heater switch when they leave their chairs, and if the electricity is wasted or if they leave it off for a long time, a fire may occur. There was a risk of causing. Therefore, the present invention eliminates the above-mentioned drawbacks, and provides a heating chair that does not waste electricity or cause a fire by forgetting to switch off the heating equipment even when a person leaves the chair. With the goal.

[0005]

[Means for Solving the Problems]

 In order to achieve the above object, in the present invention, a seat heating element provided on a seat of a chair, a warm air heating device provided below the chair and including a blower and a heating element, and the chair And a human body detection device which, when detecting a human body, energizes both of the heating elements and deenergizes both of the heating elements when the human body is not detected.

[0006]

With this structure, the heating element of the heating device provided on the chair is activated only when the human body detection device detects the human body, and when the person leaves the chair. But I never forget to switch off the heating equipment.

[0007]

【Example】

 Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings.

In FIG. 1, reference numeral 1 is a chair in which a seat heating element 3 is provided inside a seat 2. Reference numeral 4 denotes a warm air heating appliance disposed between, for example, the rear leg portions 5 of the chair 1, and an outside air intake port 7 is provided on a rear side wall portion 6a of a main body 6 of the warm air heating appliance 4 and A fan 9 which is rotationally driven by a motor 8 is arranged inside the suction port 7 to form a blower. Further, a heating element 11 is provided near the hot air outlet 10 formed on the front side wall portion 6b of the main body 6. Reference numeral 12 is a power cord.

An operating plate 13 that is elastically deformable by pressure is provided above the inside of the seat 2, and a base 14 below the operating plate 13 is always elastically biased upward. A safety switch 16 having an actuator 15 is provided. A return pile 17, which is an elastic body, is held between the operating plate 13 and the base portion 14 and always urges the operating plate 13 upward. And these comprise the pressure sensor switch 18 as a human body detection apparatus.

FIG. 3 shows an electric circuit, in which the temperature fuse 25, the power switch 21, the safety switch 16, the thermostat 22, and the seat heating element 3 are connected in series to the power supply 26, and the thermostat 22 and the seat A motor 8 is connected in parallel to the series circuit of the heating element 3, and a push button switch 23a and a series circuit of the heating element 11 are connected in parallel to the motor 8, and the push button switch 23a is connected via a diode 24. The push button switch 23b is connected in parallel.

Next, the operation will be described.

First, the power switch 21 is turned on, and one of the push button switches 23a and 23b is pressed and closed. When a person sits on the chair 1, the seat portion 2 is pressed downward as shown in FIG. Therefore, downward pressure is also applied to the operating plate 13, which has always been urged upward by the return pile 17, and is pushed downward. Then, the actuator 15 of the safety switch 16 which always elastically urges upward is also pushed downward, and the safety switch 16 is closed. As a result, the seat heating element 3 heats up to heat the seat 2, the heating element 11 heats, and the motor 8 drives the fan 9 to rotate, and the fan 9 drives the fan 9 into the main body 6 through the outside air inlet 7. Aspirate outside air. The sucked air is heated by the heating element 11, and the heated air is sent from the warm air outlet 10 to the feet of a person to heat it. At this time, the seat heating element 3 stops energization to the seat heating element 3 by the thermostat 22 when the temperature exceeds a preset temperature, and energizes the seat heating element 3 when the temperature becomes lower than the set temperature. Starting, the seat portion 2 is constantly maintained at a constant temperature. The heating element 11 of the hot-air heating appliance 4 is provided with push-button switches 23a and 23b for selecting the amount of heat generation so that the user's favorite temperature can be obtained. When the push button switch 23a is pressed, normal full-wave energization is performed, and the push button switch 23b is turned off. When the push button switch 23b is pressed, the push button switch 23a is turned off, and the amount of heat generated when the push button switch 23a is pressed can be obtained.

When the person leaves the chair 1 after studying or working, the operating plate 13, which has been pressed downward by the pressure of the person, is pushed up by the restoring pile 17 which is an elastic body. As a result, the actuator 15 of the safety switch 16 is returned upward by the urging force of the safety switch 16 to cut off the energizing circuit, so that both the heating elements 3 and 11 and the blower are de-energized.

As described above, according to the present embodiment, when a person leaves the seat portion 2 of the chair 1, the operating plate 13 which has been pressed downward by the pressure of the person until now becomes the restoring pile 17 which is an elastic body. Therefore, it is pushed up. As a result, the actuator 15 of the safety switch 16 also returns upward due to its urging force and shuts off the energizing circuit, so that both the heating elements 3 and 11 and the air blower are de-energized. Disappears.

Further, since the chair 1 and the warm air heating device 4 are integrated, it is not necessary to use a heating device separate from the indoor heating device, and the space around the desk can be effectively utilized. Wear.

In the above embodiment, the pressure when a person sits on the chair is detected by the human body detection device to energize or de-energize the heating element, but the present invention is not limited to this. For example, as a human body detection device that detects a human body, an optical sensor that detects a change in the amount of light that occurs when a person sits in a chair or an infrared sensor that detects the amount of heat generated by the human body when a person sits in a chair. It doesn't matter what you apply.

[0017]

[Effect of the device]

 As described above, according to the present invention, since the human body detection device is used in the chair, even when a person leaves the chair, the heating appliance is not forgotten to be turned off, which results in wasteful use of electricity and a long time. There is no risk of causing a fire if you forget to turn off the switch.
