Description

[Detailed Description of the Invention] The present invention relates to a heating blower that also serves as a seat for heating or keeping the human body warm in sauna rooms and other living spaces.

Generally, in order to heat or keep warm a living space such as a room and the human body therein, there is a method of irradiating or radiating the object to be heated with electromagnetic waves that are converted into thermal energy such as infrared rays, and a method of heating the object of heating by heating the air. There are two methods of filling the surrounding area and transmitting heat using the air as a medium. Heat is transmitted from the heating heat source to the heated object using these methods alone or in combination.

Up until now, as a general method, methods using air as a medium have been often used because the heat source temperature is relatively low and the thermal stimulus is mild, but when air is heated, it expands, reduces its specific gravity, and absorbs into the surrounding air. As a result, hot air rises near the ceiling even in a finite space such as a room, and the thermal energy of that air is conducted to the outside through the ceiling walls, etc., and loses thermal energy. As the temperature decreases, the specific gravity increases and it will not descend unless it becomes heavier than the next rising hot air.

Therefore, unless the object to be heated in the finite space is located on the ceiling, a decrease in heating efficiency is unavoidable.
For this reason, a method is generally adopted in which heated air is forcibly circulated and pumped into a heating effective space within a finite space, but the efficiency is greatly influenced by the pumping method.

When heating a human body in a sitting position, the most effective method is to heat the parts of the human body that are highly efficient at transmitting heat from the surface to the inside, i.e., parts with high heat transfer resistance and little subcutaneous fat layer, such as the lumbar vertebrae, dorsal vertebrae, and lower limbs. It has been revealed that this can be achieved by intensively pumping hot air from a close distance, and then setting up a flow that uses the buoyancy of the hot air to flow around the upper trunk of the body and heat it.

The purpose of this device is to centrally blow hot air directly to the waist, back, and lower limbs of a sitting person from a close distance, and the person who intends to use it can fix this heated air blower that also serves as a seat at any location. Alternatively, if it is placed movably and energized, a moderate amount of hot air will be sent out to the rear of the top of the blower and to the bottom of the front, providing intensive heating to the waist, back, lower legs, and both essential parts of the person sitting on it. It then flows around the body and performs secondary heating to achieve highly efficient heating.

Examples will be described below with reference to the drawings.

Figures 1 to 3 show its front, top, and right side views.
Further, FIG. 4 shows a front view and a central vertical sectional view, and FIG. 5 shows a partially broken perspective view.

The seat with a backrest 6 is formed into a box shape by a top plate 1, both side plates 2, 2, a front plate 3, a rear plate 4, and a bottom plate 5, and in its interior space, approximately in the center is a Shirotsko fan driven by an electric motor 14. 15
The casing 11 includes a casing 11 having a rectangular cross-sectional flow path with heating elements 12 and 13 disposed above and below the casing 11. Thus, the openings at both the upper and lower ends of the casing, that is, the upper and lower hot air ports 19, 20, the upper hot air outlet 7 provided at the rear of the upper seat plate, and the lower hot air outlet 8 provided below the seat front plate.
and are communicated with each other through wire meshes 9, 9, by substantially abutting each other.

Now, when the switch 16 is operated and electricity is received from the power supply through the cord 17, the motor 15 drives and rotates the fan 14, thereby drawing air from outside the seat box into the casing through the intake port 10 provided on the rear panel 4. A suction fan from the port 18 gives the air kinetic energy and sends it up and down in the casing flow path, giving it thermal energy as it passes around the electric heating elements 12 and 13 in the flow path. The hot air is pumped out from the upper hot air outlet 19 and the lower hot air outlet 20 at the lower end through the wire meshes 9, 9, respectively, and from the upper hot air outlet 7 and the lower hot air outlet 8, which are in communication with and almost in contact with the wire meshes 9, 9, to the outside of the seated body. In other words, the upper hot air outlet will concentrate on the waist and back parts of the human body, where the lower back is placed on the upper plate of the seated body and the back is in contact with the backrest, and the lower hot air outlet will concentrate on the lower limbs from close range. Send out hot air.

If the seat of this invention is placed inside a sauna room, for example, it will heat the air inside, giving the person sitting on the seat an effective sauna effect, and if it is brought into a living space such as a living room, it will take enough time to heat the entire room. The human body and its surroundings can be heated economically and in a short time using a much smaller amount of energy than thermal energy. As described above, the present invention provides an air heater that can be moved or fixed to a necessary location to heat a seated human body in the most economical way, thereby contributing to the lives of the people.
