Description

[0001]
[Industrial application fields]
The present invention relates to a vertical electric warmer that performs heating locally.
[0002]
[Prior art]
2. Description of the Related Art In recent years, electric hot air heaters have become widespread as heaters that can be heated manually. And a vertical type that can be used as a handbag in a stable state at a certain place for a certain period of time, such as a person sitting on a chair facing a desk and working or standing and cooking to cook The demand for electric hot air heaters is increasing.
[0003]
A conventional vertical electric warmer of this type will be described with reference to FIG.
As shown in the figure, a reflecting plate 102 is provided inside a vertically long main body 101 having a front opening, a quartz tube heater 103 is provided vertically at the focal point of the reflecting plate 102, and a protective frame 104 is provided at the front opening. A fan motor 107 for blowing air to an air flow path 106 of air blown from an air outlet 105 provided at an upper portion of the reflecting plate 102 is provided behind the reflecting plate 102, and the main body 101 is placed on a base 108. (Not shown) so that it can swing freely.
[0004]
Heating is performed while the main body 101 is swung by the radiant heat of the quartz tube heater 103, the reflected heat of the reflecting plate 102, and the warm air blown from the outlet 105 by the fan motor 107.
[0005]
[Problems to be solved by the invention]
In such a configuration of the conventional vertical electric warmer, the entire human body is heated, so that the height of the main body 101 is increased, and the cross-sectional area from the lower part to the upper part of the main body 101 is substantially the same. As the whole was swung, there was a problem that the stability was poor, the occupied area was large, and it was easily noticeable.
[0006]
This invention solves the said subject, and it aims at providing the vertical type electric warmer which can be heated according to a life posture from the step to the waist with good stability.
[0007]
[Means for Solving the Problems]
In order to achieve the above object, the vertical electric warmer of the present invention has a hollow shape with a substantially elliptical cross section and a small cross sectional area above the lower part, and a suction port provided at the rear part. A main body having a discharge port opened at a narrow angle in the part, a fan motor provided in an air flow path that sucks air from the suction port and blows out from the blow-out port, and an air flow path between the fan motor and the blow-out port. A ceramic heater provided; a wind direction changing louver provided movably at the air outlet; and a carrying handle formed on the upper rear surface of the main body. The structure is formed at the height of the knee.
[0008]
The second means is configured to reciprocate the louvers for changing the wind direction by a timing motor within a certain range.
[0009]
[Action]
According to the first aspect of the present invention, when the air blown from the fan motor is heated by the ceramic heater and the warm air is blown locally from the narrow-angle air outlet and is sitting on the chair, Efficiently warms from the feet to the waist.
[0010]
And since the cross-sectional area of the upper part side becomes small sequentially, the main body has good stability, and since the ceramic heater is also housed inside, it becomes difficult to be noticed as a heater.
[0011]
In addition, because of the configuration of the second means, the louver automatically swings in spite of local heating, so that strong and weak warm air is applied to the human body and abnormalities are observed as if it were always heated locally. Comfortable warming can be obtained without feeling the heat.
[0012]
【Example】
Hereinafter, an embodiment of the present invention will be described with reference to FIGS.
[0013]
As shown in the figure, a main body 3 having a substantially elliptical cross section, a hollow shape in which the cross-sectional area from the lower part to the upper part is gradually reduced, a suction port 1 provided at the rear part, and a suction outlet 2 opened at a narrow angle at the front part is formed. It is provided on the base 4 and the height of the main body 3 is set to the height of the human knee.
[0014]
Then, a fan motor 6 is provided in the air flow path 5 that sucks air into the main body 3 from the suction port 1 and blows out from the blower outlet 2, and the air flow path 5 is provided in the air flow path 5 between the fan motor 6 and the blower outlet 2. A ceramic heater 7 for heating the air passing therethrough and warming the air is provided, and the blower outlet 2 is provided with a louver 8 for changing the wind direction which is long in the vertical direction. A connecting shaft 11 is provided below the louver 8, and a timing motor 12 that reciprocates within a certain range is connected to the connecting shaft 11 that penetrates the lower wall of the air outlet 2.
[0015]
Further, a recessed carrying handle 13 is provided on the rear surface of the upper portion of the main body 3, and an operation portion 14 for controlling energization of the fan motor 6, the ceramic heater 7 and the timing motor 12 is provided on the upper surface of the main body 3. The configuration.
[0016]
In the above configuration, when the fan motor 6 and the ceramic heater 7 are energized by operating the operation unit 14, the air sucked from the suction port 1 is sent to the ceramic heater 7 through the air flow path 5 by the fan motor 6. The warm air heated by the heater 7 and warmed is blown out from the air outlet 2, and when sitting on a chair, it is warmed almost from the feet to the waist.
[0017]
At this time, the blowing direction is changed by changing the direction of the louver 8.
When the timing motor 12 is energized, the connecting shaft 11 is reciprocally rotated within a certain range by the timing motor 12, and the air direction of the louver 8 is automatically changed accordingly, thereby blowing air.
[0018]
As described above, according to the vertical electric warmer of the embodiment of the present invention, the main body 3 is formed in a shape in which the cross-sectional area from the lower portion to the upper portion is sequentially reduced, and the height of the main body 3 is approximately the height of a human knee. Because it is formed in a stable, it can be warmed efficiently from the feet you want to get warm to around your waist, and the ceramic heater 7 is housed inside, making it less noticeable as a heater, near the reception desk Even if it is installed in an outpatient, it will not be noticed by an outpatient and will not give a sense of incongruity.
[0019]
Further, by automatically swinging the louver 8, it is possible to reduce abnormal heating locally and to obtain a comfortable warming.
[0020]
【The invention's effect】
As is clear from the above embodiments, according to the present invention, the cross section is substantially elliptical and the cross-sectional area from the lower part to the upper part is hollow and the suction part is provided at the rear part, and the front part is opened at a narrow angle. A body formed with an air outlet, a fan motor provided in an air flow path that sucks air from the air inlet and blows out from the air outlet, a ceramic heater provided in an air flow path between the fan motor and the air outlet, Because it has a louver for changing the wind direction movably provided at the air outlet, and a carrying handle formed on the upper rear surface of the main body, the main body is formed at the height of the knee. It is possible to provide a vertical electric warmer that has good stability and can heat from the feet to the waist according to the lifestyle.
[0021]
Moreover, since the louver for changing the wind direction is configured to reciprocate within a certain range by the timing motor, comfortable warming can be obtained without feeling abnormal heat.
