[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a base portion, a body portion provided on the upper portion of the base portion, a head portion located above the body portion, and a heat generating portion disposed in front of the head portion and supported by the head portion. It is related with the electric fan type heating apparatus provided with.
[0002]
[Prior art]
As an indoor heating device, one using liquid fuel or gaseous fuel such as a stove or a gas fan heater is known. These generate heat by burning fuel and attempt to warm the room temperature. However, the heating apparatus using these fuels must be ventilated by opening a window because indoor air becomes turbid as combustion gas is generated. Therefore, it is troublesome and troublesome for the residents to ventilate. In addition, ventilation causes heat loss, which is inefficient and increases fuel costs.
[0003]
On the other hand, a fan-type heating device is known. For example, there is a heating device disclosed in Utility Model Registration No. 3078539. This heating device is similar in appearance to a fan, and has the advantage of being easy to carry and easy to handle. Similar to the electric fan, the heating device includes a base part, a body part provided on the upper part of the base part, and a head part located above the body part. In the case of an electric fan, a blower unit having blades is arranged in front of the head unit. In the case of a heating device, a heat generating unit is arranged instead of the blower unit.
The heating unit includes a halogen heater, a reflector that reflects heat generated by the heater toward the front, and a safety net (protective cover) that is provided on the forefront of the heater and protects the heater and the reflector. ). The protective cover is provided so as not to touch the blades even in the case of the electric fan, but is provided so as not to touch the heater or the reflection plate also in the case of the heating device.
[Problems to be solved by the invention]
However, unlike the case of the electric fan, in the case of the heating device, the protective cover itself is heated by the heater. Further, the protective cover is often made of metal in order to ensure a desired strength. Due to the good thermal conductivity of the metal, touching the protective cover may cause burns. Therefore, it is necessary to devise a technique that prevents the user of the heating apparatus from being burned by touching the protective cover.
Furthermore, when a halogen heater is used as the heater, the user may feel dazzling light reflected by the reflecting surface. Therefore, it is desirable to take measures so that the user does not feel dazzling.
[0004]
The present invention has been made in view of the above circumstances, and the problem is that the electric fan does not burn even when the user touches the protective cover, and the user does not feel dazzling during use. It is to provide a mold heating device.
[Means for Solving the Problems]
In order to solve the above problems, a fan-type heating device according to the present invention includes a base part, a body part provided at an upper part of the base part, a head part located above the body part, and a front part of the head part. are arranged, e Bei and a heating unit which is supported by the head portion, the heat generating portion, a halogen heater, and a reflecting surface for reflecting the heat generated by the heater to the front, the heating unit A protective cover for protecting the heater and the reflective surface is provided at the foremost part of the protective cover, and flocking colored in a color having an antiglare effect is applied to the outer surface of the protective cover. what der those with the center portion of the reflective surface in such a form that it protrudes forward, the cylindrical supporting member is attached, and, at the front side of the cylindrical support member, the heater is supported Like so Is further to the rear side of the cylindrical support member, the small holes for heat radiation is characterized that you have been a large number along the circumferential direction.
In the electric fan type heating device having this configuration, the outer surface of the protective cover that protects the heater and the reflection mechanism is flocked. As a material used for flocking, a material having a lower thermal conductivity than that of a metal is used. Therefore, even if the user touches the protective cover, there is no worry of being burned. In addition, the flocked hair is matte and colored with an anti-glare effect (not dazzling), so there is no sense of incompatibility even if it is placed indoors. As a result, it is possible to provide a fan-type heating device that can solve the problems of the present invention.
[0005]
As a preferred embodiment of the present invention, provided with a heat radiation prevention cover provided on the front surface of the heater and on the rear surface side of the protective cover to prevent heat generated from the heater from being directly radiated forward,
In the central region of the protective cover that faces the heat dissipation prevention cover, there is a configuration in which no flocking is applied.
[0006]
When the heat from the heater is radiated directly forward, the user may feel quite dazzling. By providing the heat dissipation prevention cover, it is possible to prevent the forward emission of heat generation. Further, when flocking the protective cover, it is not necessary to plant the whole area of the protective cover. In the central area facing the heat radiation prevention cover, no heat is dissipated, so there is no need to plant hair. Thereby, the amount of flocking can be reduced.
[0008]
A cylindrical support member is attached to the center of the reflective surface, and the heater is supported on the front side. In other words, the reflective surface and the heater are arranged at a distance. Thereby, the heat radiation from the heater can be reflected over the entire reflection surface. Moreover, since many small holes for heat dissipation are formed along the circumferential direction on the rear side of the cylindrical support member, heat storage inside the cylindrical support member can be prevented.
[0009]
As still another preferred embodiment of the present invention, the heater is configured as a linear heater having an arc-shaped portion and linear portions extending from both ends of the arc-shaped portion, and the arc-shaped portion and the straight line The support part which supports a heater is provided in the shape part, and this heater is attached to the heat radiation prevention cover by fixing this support metal part to the back side of the heat radiation prevention cover.
[0010]
By forming the heater in a linear shape and attaching the heater to the heat radiation prevention cover via the support metal fitting, the heater can be reliably fixed.
[0011]
As still another preferred embodiment of the present invention, the support metal fitting is configured to be fitted into the outer peripheral portion of the cylindrical support member on the front side, and thereby, on the front side of the cylindrical support member. The heater is supported.
[0012]
With this configuration, a plurality of support metal fittings can be positioned on the outer peripheral portion on the front side of the cylindrical support member. Thereby, a heater can be reliably supported by the front side of a cylindrical support member.
[0013]
As still another preferred embodiment of the present invention, a fixed shaft member provided so as to penetrate the inside along the axial direction of the cylindrical support member,
A front end portion of the fixed shaft member is fixed to the heat radiation prevention cover, and a rear end portion is fixed to a base plate attached to the head portion.
[0014]
Although the heater is attached to the heat radiation prevention cover and is supported on the front side of the cylindrical support member, it is necessary to fix the heater itself to the main body of the electric fan type heating device. Therefore, using the fixed shaft member, the front side of the fixed shaft member is fixed to the heat radiation prevention cover, and the rear side is fixed to the base plate attached to the head portion. Thus, the heater is reliably fixed to the main body by the support metal fitting, the heat radiation prevention cover, and the fixed shaft member.
[0015]
As still another preferred embodiment of the present invention, the cylindrical support member is formed by rolling a flat plate member formed by pressing into a cylindrical shape.
[0016]
The cylindrical support member is formed in a cylindrical shape. However, in order to form such a shape, a flat plate member formed by pressing is rounded into a cylindrical shape, so that the cylindrical support member can be easily formed into a cylindrical shape.
[0017]
DETAILED DESCRIPTION OF THE INVENTION
A preferred embodiment of a fan type heating device according to the present invention will be described with reference to the drawings. FIG. 1 is an external perspective view seen from the front of the electric fan type heating device, and FIG. 2 is an external perspective view seen from the side.
[0018]
This heating device includes a base portion 1, a body portion 2 provided on the upper portion of the base portion 1, a neck portion 6 provided on the upper portion of the body portion 2, and a head portion 5 provided on the upper portion of the neck portion 6 ( And the heat generating part provided in front of the head part 5.
[0019]
The base part 1 is a part installed on the floor surface in the room, and has a wide flat part. The base unit 1 is provided with an operation knob 7 and can be set to any one of “OFF”, “ON”, and “ON (swing)”.
[0020]
The trunk | drum 2 is carrying out the elongate shape extended to an up-down direction, and has the fixing | fixed part 2a and the expansion | extension part 2b. The fixed part 2 a is fixed to the base part 1. The extending part 2b can move up and down relatively with respect to the fixed part 2a, and can adjust the height of the heat generating part. Moreover, the inside of the trunk | drum 2 is formed hollow in order to let wiring pass.
[0021]
The neck portion 6 is attached to the elongated portion 2b by a hinge mechanism so that the heat generating portion can be swung in the vertical direction (in the vertical plane). In other words, the heat generating part can be adjusted in the upward, horizontal, and downward directions.
[0022]
Inside the head unit 5, a swing mechanism in the horizontal direction, a support mechanism for the heat generating unit, and the like are incorporated. The structure of the base part 1, the trunk | drum 2, the neck part 6, and the head part 5 is provided with the structure similar to an electric fan.
[0023]
The heat generating part includes a reflective surface support part 4 and a protective cover 3 attached to the front surface of the reflective surface support part 4. The reflective surface support 4 and the protective cover 3 are formed in a circular shape when viewed from the front.
[0024]
Next, details of the heat generating portion will be described. FIG. 3 is an exploded perspective view showing the details of the heat generating part, and FIG. 4 is a side sectional view showing the internal structure of the heat generating part and the head part 5. FIG. 5 is a diagram showing details of the heater mounting structure, and FIG. 6 is a diagram showing a support cylinder 42 that supports the heater.
[0025]
A reflection plate 40 constituting a reflection mechanism is attached to the front surface of the reflection surface support section 4. The reflection plate 40 is formed with a reflection surface 40 b made of aluminum and an attachment hole 40 a for attaching the protective cover 3 to the reflection surface support portion 4. The reflective surface 40b is formed in a predetermined concave surface in order to efficiently reflect heat forward. In addition, the reflective surface support part 4 is formed with a synthetic resin. Further, a grip portion 4a for carrying by hand is also integrally formed.
[0026]
The protective cover 3 includes a disc 31 located at the center, spoke portions 32 formed in a large number radially from the center of the disc 31, and a ring portion 30 located on the outermost periphery. Each of these parts is coupled by a known method. The protective cover 3 is provided in order to prevent the hand from touching the internal mechanism as in the case of the electric fan. Among the parts constituting the protective cover 3, the ring portion 30 and the spoke portion 32 are subjected to electrostatic flocking on the outer surface. As for the ring part 30 and the spoke part 32, a core material is formed with a metal. This is to ensure a desired strength. However, since the protective cover 3 is heated by the heat reflected by the reflective surface 40b, there is a possibility that the hand may feel hot or may be burned when the protective cover 3 is touched. Therefore, although the core material is metal, electrostatic flocking is applied to the outer surface so that there is no problem even if it is touched by hand.
[0027]
In addition, the flocking is not glossy and is colored in a color having an antiglare effect. This eliminates the need for the user to feel dazzling. Examples of colors include black, dark ash, brown, dark brown, blue, ultramarine blue, and purple.
[0028]
This flock is formed by short fibers (pile). As the short fiber, for example, cotton, 6 nylon, 66 nylon, polyester or the like is used as a material. Moreover, the short fiber can be dyed in a color having an antiglare effect. Such materials have a much lower thermal conductivity than metals. Therefore, even when the heating device is in use, there is no problem even if it is touched by hand because it does not become so hot.
[0029]
In addition, about the disc 31 (equivalent to the center area | region of a protective cover) of the center part among the protective covers 3, it is not necessary to give flocking. This is because this portion is a position where heat does not pass due to the arrangement of the heater protection cover 41 described later. This eliminates the need for flocking more than necessary. Of course, electrostatic flocking may also be applied to this disc 31 just in case.
[0030]
As shown in FIGS. 3 and 4, two coupling bolts 45 (corresponding to a fixed shaft member) are attached and fixed to the rear surface of the heater protection cover 41 (corresponding to a heat radiation prevention cover). A heater protection cover 41 is provided at a position facing the rear surface of the disc 31, and a halogen heater 43 is provided therein. The inner surface (rear surface) of the heater protection cover 41 is formed as a reflection surface 41e that functions as a reflection mechanism, and reflects the heat generated by the halogen heater 43 (heat by light) toward the reflection plate 40. That is, the heat generated by the halogen heater 43 is reflected not only directly by the reflecting surface 40b but also by the reflecting surface 41a of the heater protection cover 41, and then reflected by the reflecting surface 40b. Things will also be included.
[0031]
A support cylinder 42 (corresponding to a cylindrical support member) is provided to fix the heater protection cover 41 to the reflection plate 40. The support cylinder 42 can be coupled to the reflector 40 and the heater protection cover 41 by an appropriate method such as fitting or caulking. As shown in FIG. 4, the inside of the support cylinder 42 is hollow, and is used as a space for arranging the coupling bolt 45 and passing the cord wire 44 of the halogen heater 43. Further, several small holes 42a are formed on the outer periphery of the support cylinder 42 so that heat is not accumulated inside. A large number of small holes 42 a are formed along the circumferential direction on the rear side in the cylindrical axis direction of the support cylinder 42. Moreover, the small hole 42a is formed in the long hole-shaped hole along the axial direction.
[0032]
In order to couple the protective cover 3 to the reflecting surface support portion 4, a pressing metal 7 is provided. The protective cover 3 is pressed against the reflecting surface support portion 4 by the pressing metal 7 and fastened by the screws 8. A hole 40a through which the screw 8 passes is formed in the outer peripheral portion of the reflecting plate 40. In FIG. 3, only one presser metal fitting 7 is shown, but a plurality of presser fittings are actually used.
[0033]
Inside the head portion 5, a swing motor 50, a mounting base plate 52, and a swing mechanism 53 are provided. The above-described coupling bolt 45 is coupled to the mounting base plate 52 by a nut 46. Thereby, the heat generating part is supported by the head part 5. The reflection surface support 4 is also fixed to the base plate 52 with screws. The swing mechanism 53 is a known mechanism, and details thereof are omitted. With this swing mechanism 53, the heat generating portion can be swung in a horizontal plane. The internal structure of the head unit 5 is protected by a cover member 54.
[0034]
The cord wire 44 of the halogen heater 43 and the cord wire 51 of the motor 50 are both connected to a circuit provided inside the base portion 1 through the body portion 2.
[0035]
In the base portion 1, a cord line 11 and an electronic circuit 10 for connecting to a commercial power source are provided. The electronic circuit 10 controls and drives the halogen heater 43 and the motor 50 according to the operation of the operation knob 9.
[0036]
<Detailed structure of heat generating part>
Next, the detailed structure of the heat generating portion will be described with reference to FIGS. FIG. 5 shows details of the heater mounting structure. The halogen heater 43 is provided with heating wires 43a therein, and lead wires 43b are connected to both ends of the heating wires 43a. The halogen heater 43 is a linear heater, and includes an arc-shaped portion 43c and linear portions 43d extending at both ends of the arc-shaped portion 43c.
[0037]
The halogen heater 43 is attached to the heater protection cover 41, and three support fittings 49 are used for the attachment. The support metal fitting 49 has a substantially Z shape, and the heater support portion 49 a is used at one place on the arc-shaped portion 43 c of the halogen heater 43 and two places on the linear portion 43 d so as to hold the halogen heater 43. The standing wall portion 49c of the support metal fitting 49 has an inner wall surface, and this inner wall surface faces the direction of the circle center of the arcuate portion 43a. The three inner wall surfaces constitute a fitting portion that fits to the outer periphery of the support cylinder 42 on the tip side. The support metal fitting 49 has an attachment portion 49b in which an attachment hole is formed. Corresponding to the attachment portion 49b, the heater protection cover 41 is formed with three attachment holes 41c. The support metal fitting 49 is attached to the heater protection cover 41 by the eyelet pin 20. It may be fixed with caulking instead of eyelet. The heater support portion 49a and the attachment portion 49b of the support metal fitting 49 have surfaces (parallel surfaces) in the same direction, and the standing wall portion (inner wall surface) 49c is orthogonal to them. Thereby, the shape of the support metal fitting 49 is substantially Z-shaped.
[0038]
The coupling bolt 45 described above is formed in a shaft shape extending in the front-rear direction. The front end of the coupling bolt 45 is fixed to the mounting bracket 47. An internal thread 45 a is formed at the rear side end of the coupling bolt 45. The mounting bracket 47 has two stepped portions 47a on both sides thereof, and mounting holes are formed in the stepped portion 47a. The mounting bracket 47 is fixed at a position of a mounting hole 41 d formed in the heater protection cover 41 by a caulking pin 48. Thereby, the front side of the coupling bolt 45 is fixed to the heater protection cover 41. The heater protective cover 41, the halogen heater 43, and the coupling bolt 45 are an integrated unit.
[0039]
FIG. 6 is a diagram showing the configuration of the support cylinder 42. (A) shows the assembled state, and (b) shows the unfolded state. Although it is cylindrical when assembled, it does not have to be a strict cylinder, and may be formed in a truncated cone (ie, cylindrical). As already described, the support cylinder 42 has many small holes 42a for heat dissipation. In the unfolded state, it is formed as a press-molded flat plate member. By rolling the flat plate member shown in (b), the cylindrical shape shown in (a) is obtained. Moreover, it is necessary to maintain a shape after rounding. Therefore, the engagement hole 42b is integrally formed at one end portion to be abutted when rounded, and the engagement protrusion 42c is integrally formed at the other end portion. And after rounding a flat plate member, a cylindrical shape can be maintained by inserting the engaging protrusion 42c into the engaging hole 42b.
[0040]
Next, a procedure for assembling the heat generating portion will be briefly described. A reflection plate 40 is attached to the reflection surface support portion 4, and a support cylinder 42 is attached to the center of the reflection surface 40. After attaching the support cylinder 42 to the reflection surface 40, these units may be attached to the reflection surface support portion 4. Next, the unitized halogen heater 43, heater protection cover 41, and coupling bolt 45 are assembled so as to be inserted from the front side of the support cylinder 42. At this time, the inner wall surfaces (three places) of the standing wall portion 49c of the support metal fitting 49 are fitted to the outer peripheral portion on the front side of the support cylinder 42. Thereby, the halogen heater 43 is supported on the front side of the support cylinder 42. Further, the female screw 45 a of the coupling bolt 45 is inserted into holes (two places) formed in the standing wall portion 52 a of the base plate 52. Then, the nut 46 is screwed into the female screw 45a. Thereby, the heater unit is fixed to the main body.
[0041]
<Configuration of the device for flocking>
FIG. 7 is a conceptual diagram showing an apparatus for applying electrostatic flocking to the protective cover 3. The protective cover 3 is suspended by a hanging jig 60 and is electrically grounded. In addition, pile supply devices 64 are provided on both sides so as to sandwich the protective cover 3, and an electrode 61 is disposed inside the pile supply device 64. The electrode 62 is covered with an insulating material. The electrodes 61 and 62 are applied with a high voltage. Since the short fiber (pile) supplied by the pile supply device 64 is charged by the electrode 61 and the protective cover 3 is grounded, the short fiber is directed toward the protective cover 3 by the electrostatic force. Further, since the electrode 62 is further provided, there is an effect of synergistically strengthening the electric field. Thereby, the suction | attraction force with respect to the protective cover 3 of a short fiber is strengthened.
[0042]
Note that an adhesive is applied to the surface of the protective cover 3 in advance. Thereby, the short fiber adhering to the surface of the protective cover 3 is firmly bonded. As the adhesive, acrylic, urethane, epoxy and the like are preferably used. The adhesive is applied by an appropriate method such as spray coating or dipping.
<Another embodiment>
The structure disclosed in this embodiment is merely an example, and the present invention is not limited to this.
