Description

[Detailed explanation of the invention] (a) Industrial application field This invention is used for human body heating in vehicles (engine-powered) that do not have a heating space shielded from the outside air around the driver's seat, such as motorcycles and tractors. It is related to the device.

(b) Conventional technology In the past, the number of users of motorcycles has been increasing because anyone can easily ride a motorcycle, it is convenient, and maintenance costs are low. It is natural that they are not equipped with a heating device because they do not have a heated space.

(c) Problems that the invention aims to solve As mentioned above, since motorcycles are not equipped with heating devices, it is extremely painful to use them on cold days.

This is an extremely serious problem, especially in cases where the use of motorcycles is mandatory, such as for mail delivery, as it is not possible for people to use other means of transportation only on cold days like the average person.

The same applies to work vehicles such as tractors and forklifts.

Therefore, the present invention solves this problem and uses heat generated by the engine, even in vehicles such as motorcycles that do not have a heated space shielded from the outside air around the driver's seat. To provide a human body heating device for an engine-powered vehicle, which can directly and efficiently heat the human body by creating a heating space between the body and clothing, and which can be driven comfortably even on cold days.

(d) Means for solving the problem The gist of the present invention is to provide a heat exchanger that heats air using the heat generated by the engine as a heat source, and a system that uses air heated by the heat exchanger to be blown out from behind the driver's seat. The air blowing nozzle unit is equipped with a duct for feeding into the nozzle unit and an air blower, the blowing nozzle unit is installed in a state that projects upward from the bottom surface at a required height at the rear of the driver's seat, and a hot air blowing outlet is provided at the upper part of the blowing nozzle unit. The present invention is characterized by a human body heating system for engine-powered vehicles.

(E) Effect In this invention, the human body is directly exposed to warm air by operating the blow nozzle unit installed upright at the rear of the driver's seat, inserted from the hem of the jumper, etc., between the jumper and the human body. It is heated.

(F) Embodiment Figures 1 and 2 show an embodiment of the present invention when used on a motorcycle.
indicates a heat exchanger, B indicates a blowing nozzle unit, C indicates a duct, and D indicates a blower.

The heat exchanger A heats air using the heat generated by the engine 1 as a heat source, and in this embodiment, a case is shown in which exhaust heat from the engine 1 is used. Further, in this embodiment, a case is shown in which an engine cooling fan is used as the fan D. That is, the outer periphery of the exhaust pipe 3 between the engine 1 and the muffler 2 is surrounded by an outer cylinder 4 to form an air heating chamber 5, and a large number of heat fins 6 are erected around the outer periphery of the exhaust pipe 3 to form a heat exchanger. A, and the air intake side of the outer cylinder 4 is connected to an exhaust port 7 branched to the exhaust side of the engine cooling blower.

Next, the blow-off nozzle unit B is erected at the rear of the driver's seat E so as to protrude above the seat surface 8 by a required height, and is provided with a hot air blow-off port 9 at its upper end. It is desirable that the blow-off nozzle unit B be formed to be as thin as possible in the front-rear direction, and be slightly curved to follow the curved surface of the human body.

Further, the duct C connects the heat exchanger A and the blowing nozzle unit B, and the heat exchanger A side is connected to the hot air blowing side of the outer cylinder 4. Note that 1 in the figure
0 is a switching damper installed in the middle of the duct C, which serves to stop the air blowing to the blow-off nozzle unit B and at the same time discharge warm air to the outside from the exhaust port 11, thereby eliminating the need for heating. Used in cases.

In addition, if the opening degree of this damper 10 is configured to be able to be changed as desired, the blowout nozzle unit B
The amount of hot air flowing to the side can be adjusted, and the heating temperature can be adjusted.

In this embodiment, a case is shown in which the exhaust heat of the engine 1 is used as the heat exchanger A, but in the case of a water-cooled engine or the like, heat of cooling water may also be used. Furthermore, instead of using an engine cooling blower as the blower D, the amount of air blown can be adjusted by providing a separate blower.

Since this embodiment has the above configuration, when sitting in the driver's seat E of a motorcycle or the like as shown in FIG. When operated with the engine inserted between the two, exhaust heat from the engine 1 is converted into clean heated air by the heat exchanger A, and this heated air is turned into warm air by the blower D, which is then passed through the duct D and the blow-off nozzle unit B. The hot air is sent between the jumper and the human body from the air outlet 9, and the human body is heated directly and efficiently by the hot air sent in.

(g) Effects of the invention As explained in detail above, according to the invention, the heat generated by the engine can be effectively used to directly and efficiently heat the human body, and the hot air blowing nozzle unit can be placed in the driver's seat. The hot air outlet is installed at the rear of the jumper so that it protrudes above the seat surface at a required height, and the hot air outlet is provided at the top of the nozzle unit, making it easy to introduce hot air into the jumper while sitting in the driver's seat. It can be done easily and quickly with natural movements, and because of its upright position, it does not get in the way of driving or working, so it can be operated comfortably even on cold days, and it can also improve work efficiency. effective.
