Description

  The present invention relates to a floor-standing type hot air heater provided with a hot air outlet on the front side, and more particularly, a floor-standing type provided with a pedestal at the bottom and swinging the main body of the hot air heater by the pedestal. It relates to hot air heaters.

  Conventionally, this type of floor-standing type hot air heater is configured to blow out hot air toward the front thereof. And when directing the blowing direction of warm air to the desired direction, generally the whole heater was lifted and the direction of the heater was changed. However, when the direction of the hot air is changed, an operation of lifting the entire heater is required every time, so there is an inconvenience that it is extremely troublesome.

  Then, what provided the base which makes the lower part of a heater main body rotatable the heater main body is known (for example, refer patent document 1). In other words, this type of pedestal includes a rotary shaft extending in the vertical direction at a substantially central portion, and the heater main body can be rotated around the rotary shaft so that the heater main body can be directed in a desired direction. ing.

  However, this type of heater body has a generally rectangular shape in plan view with the left-right direction being the longitudinal direction, and the heater body is supported by the rotating shaft. Load is likely to occur. When the uneven load is generated in the main body of the heater, there is a backlash in the direction intersecting with the axis of the rotation axis, which may cause the main body of the heater to tilt to the left or right, as well as smooth. There is an inconvenience that obstructs rotation.

  Also, in order to prevent rattling during rotation, a rotating plate made of an annular synthetic resin block is fitted in the vicinity of the outer periphery of the rotating shaft to increase the degree of adhesion between the heater body and the base. It has been proposed (see, for example, Patent Document 2).

  However, by providing a rotating plate around the rotating shaft, the rotating plate is always in sliding contact between the heater body and the pedestal even if the rattling caused by the uneven load on the heater body can be suppressed. For this reason, frictional resistance is generated during rotation, and smooth rotation may be hindered. In addition, in a warm air heater having a generally rectangular shape in plan view in which the left-right direction is the longitudinal direction, the uneven load generated in the left-right direction of the rotating shaft is relatively large, and a rotating plate is fitted near the outer periphery of the rotating shaft. There is a disadvantage that the inclination of the main body of the heater cannot be sufficiently suppressed only by itself.

Furthermore, in this type of heater, in order to use a household power source when performing heating operation, the power cord is extended from the heater body, and when the heater body is rotated, the heater body It is conceivable that the power cord enters and bites between the pedestal and the pedestal, and this may also prevent smooth rotation.
Japanese Utility Model Publication No. 3-118471 (FIGS. 1 and 7) Japanese Utility Model Publication No. 61-66711 (FIG. 1)

  In order to eliminate such inconvenience, the present invention suppresses the inclination of the main body of the heater due to an unbalanced load, prevents the power cord from being bitten during rotation, and allows the heater body to rotate smoothly. It aims at providing a type warm air heater.

In order to achieve such an object, the present invention provides a floor-standing warm air heater having a hot air outlet on the front side and a pedestal at the bottom, wherein the pedestal includes a base in contact with the floor surface; A main body mounting plate that is provided on the upper portion of the base with a gap and that integrally mounts the main body of the heater, a rotary shaft that rotatably connects the main body mounting plate to the base, and the rotation angle of the body mounting plate according to the rotation axis and a rotation restricting means for restricting a predetermined range, prior SL body mounting plate is formed in a generally rectangular plan view shape extending in the left-right direction, the group The base includes a main pedestal portion having substantially the same shape as the main body mounting plate in plan view, and a sub pedestal portion extending in the front-rear direction of the main pedestal portion, and the main body mounting plate includes the main body mounting plate. And a projection that projects into the gap toward the main pedestal portion when the front-rear direction of the main pedestal portion is matched, When the main body mounting plate is rotated relative to the base from a state in which the front and rear directions of the main body mounting plate and the main pedestal portion are matched, the main body of a portion that is disengaged from above the main pedestal portion The rotation restricting means is formed on the lower surface of the mounting plate in the front-rear direction, and the rotation restricting means is configured to use the main body mounting plate as the base from a state in which the front-rear direction of the main body mounting plate and the main pedestal portion are matched. In contrast , at least a part of the projection of the main body mounting plate is restricted to a range where the main base plate is positioned above the main pedestal when rotated .

  In the hot air heater of the present invention, the pedestal is constituted by the base and the main body mounting plate, and the base and the main body mounting plate are connected by the rotating shaft, whereby the hot air heater is provided. The direction of the warm air blown from the front side of the can be changed to a desired direction. And in this invention, since the said protrusion was provided in any one of the opposing surfaces where the said base and the said main body mounting plate mutually oppose, an unbalanced load is applied to a heater main body, and a heater main body is When the tilt is applied, the protrusion can be brought into contact with the other of the opposing surfaces of the base and the main body mounting plate to regulate the tilt of the main body of the heater. As a result, the load applied in the direction intersecting the rotation axis of the rotation shaft can be reduced, and the heater body can be smoothly rotated.

Furthermore, by providing the projection on the main body mounting plate, the projection can be prevented from being visually recognized from the outside, and the appearance of the heater can be prevented from being damaged by the projection. Further, the rotation angle of the main body placement plate regulated by the rotation regulating means (that is, the range to be swung) is a range in which at least a part of the protrusion is located above the main pedestal portion, so that the main body has a maximum angle. Even if the mounting plate is rotated, the protrusion does not come off the upper position of the main pedestal portion, and the inclination of the main body of the heater can be prevented in the entire rotation range of the main body mounting plate.

  Also, in the present invention, the main pedestal portion is provided with another protrusion that protrudes upward at a position facing the protrusion of the main body mounting plate or at an outer position than the protrusion. And

  According to the present invention, by providing the other protrusion on the main pedestal portion, even if the power cord is extended from the main body of the heater, the main body is placed without entering inside the other protrusion. When the plate is rotated, the power cord is prevented from biting between the main body mounting plate and the base, and a smooth rotation swinging operation can be obtained.

  At this time, the rotation restricting means is a part of the first non-exposed portion that is formed on the upper surface of the main pedestal portion so as to cover the main body placement portion when the main body placement plate is rotated in one direction. And a portion of the second non-exposed portion that is covered with the main body mounting portion and formed on the upper surface of the main pedestal portion when the main body mounting plate is rotated in the other direction. It is preferable that the rotation angle of the main body mounting plate is restricted within a range where the non-exposed portion is formed, and the other protrusion is formed on the third non-exposed portion.

  That is, when the main body mounting plate is rotated to the maximum angle in one direction and the main body mounting plate is restricted by the rotation restricting means, a part of the main body mounting plate is located above a part of the main pedestal portion. The first non-exposed portion is formed for covering. Similarly, when the main body mounting plate is rotated to the maximum angle in the other direction and the main body mounting plate is restricted by the rotation restricting means, the upper part of the main pedestal portion is similarly positioned above the main body mounting plate. Since the portion is covered, the second non-exposed portion is formed. The rotation restriction range by the rotation restriction means is set to a range in which a portion where a part of the first non-exposed part and a part of the second non-exposed part overlap each other is formed. It is possible to form the third non-exposed portion that is not exposed even if the is rotated in any direction. Then, by forming the other protrusion at a position that becomes the third non-exposed portion of the main pedestal portion, it is possible to prevent the other protrusion from being visually recognized from the outside. It can prevent that the external appearance of a heater is impaired by the protrusion.

  An embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a perspective view showing a floor-mounted hot air heater according to this embodiment, FIG. 2 is an explanatory front view showing a pedestal of this embodiment, and FIG. 3 is an explanatory side view showing a pedestal of this embodiment. 4 is an explanatory plan view showing the base of the pedestal of this embodiment, FIG. 5 is an explanatory bottom view showing the main body mounting plate of the pedestal of this embodiment, and FIG. 6 is the pedestal of this embodiment. It is explanatory drawing which shows the principal part.

  A warm air heater 1 of this embodiment shown in FIG. 1 is a floor-standing type that is placed on the floor in a room, and is provided with a pedestal 3 that supports the heater body 2. The heater body 2 has a depth dimension smaller than the width dimension on the front side, and is formed in a substantially rectangular shape that is long to the left and right when viewed in plan. Although not shown in the figure, a gas combustion device or a blower for generating warm air is built in the heater main body 2, and a hot air outlet 4 is provided on the front side as shown in FIG. Is provided. Further, a gas supply pipe (not shown) for supplying fuel gas of the gas combustion device and a power cord 5 connected to a household power source as a driving power source for the blower are extended from the rear portion of the heater body 2. .

  As shown in FIGS. 2 and 3, the pedestal 3 includes a main body mounting plate 6 that also serves as a bottom closing plate of the heater main body 2 and a base 7 that is in contact with the floor in the room. The base 7 includes a rotating shaft 8 extending upward, and the main body mounting plate 6 is rotatably connected to the upper portion of the base 7 via the rotating shaft 8.

  As shown in FIGS. 3 and 4, the base 7 includes a main pedestal portion 9 and a sub pedestal portion 10 that extends before and after the main pedestal portion 9. The main pedestal 9 is substantially the same in plan view shape as the main body placing plate 6, and the sub pedestal 10 is provided to increase the stability of the main pedestal 9. As shown in FIG. 4, the rotation shaft 8 is provided in the center of the main pedestal portion 9, and a stopper 11 described later is provided on the main pedestal portion 9 in the vicinity of the rotation shaft 8. . Further, a pair of restricting protrusions 12 (other protrusions in the present invention) are formed at a position at a predetermined distance on the left and right sides of the rotating shaft 8 (this position will be described in detail later).

  As shown in FIG. 5, the main body mounting plate 6 has a rotation connecting hole 13 that is rotatably fitted to the rotation shaft 8 of the base 7 and a rotation restricting hole into which the stopper 11 of the base 7 is inserted. 14. The stopper 11 and the rotation restricting hole 14 constitute the rotation restricting means of the present invention. Further, a pair of support protrusions 15 (protrusions in the present invention) are formed at positions where a predetermined distance on the left and right sides of the rotation connecting hole 13 exists. Both support protrusions 15 extend in a curved shape along the circumference around the rotation shaft 8.

  Then, by assembling the main body mounting plate 6 on the base 7 via the rotating shaft 8, the main body mounting plate 6 (and the heater main body 2) are rotatably connected as shown by phantom lines in FIG. Is done. As a result, the stopper 11 of the base 7 is inserted into the rotation restriction hole 14 of the main body placing plate 6, and the rotation angle of the main body placing plate 6 is restricted within a predetermined range. Moreover, each regulation protrusion 12 which protrudes on the base 7 and a part of each support protrusion 15 which protrudes under the main body mounting board 6 mutually oppose. In other words, the support protrusions 15 and the restricting protrusions 12 protrude into the gap formed between the base 7 and the main body mounting plate 6. A slight gap is formed between the restricting protrusion 12 and the support protrusion 15 facing each other (see FIG. 6).

  As shown in FIG. 4, when the main body mounting plate 6 on the base 7 is rotatable, the main body mounting plate 6 and the heater main body 2 can be rotated, and the outlet 4 of the heater main body 2 is rotated. (See FIG. 1) can be directed in a desired direction. Further, the rotation angle of the main body mounting plate 6 is restricted within a predetermined range by the stopper 11 of the base 7 and the rotation restricting hole 14 of the main body mounting plate 6, thereby preventing excessive rotation of the main body mounting plate 6. can do.

  Further, in FIG. 4, when the main body placement plate 6 is rotated clockwise (clockwise) to reach the maximum restriction angle, the first non-exposed portion A is partially formed on the main pedestal portion 9 of the base 7. Is formed. When the main body placement plate 6 is rotated clockwise (clockwise) to reach the maximum restriction angle, the first non-exposed portion A is formed on a part of the main pedestal portion 9 of the base 7. When the main body placing plate 6 is rotated counterclockwise (counterclockwise) to reach the maximum restriction angle, the second non-exposed portion B is formed on the other portion of the base 7 on the main pedestal portion 9. Further, the stopper 11 of the base 7 and the rotation restricting hole 14 of the main body placing plate 6 are set when the main body placing plate 6 is rotated to the right (rotated clockwise) to reach the maximum restriction angle, and when the main body is placed. The rotation is restricted so that a non-exposed portion is formed on the main pedestal portion 9 both when the plate 6 is rotated counterclockwise (counterclockwise) to reach the maximum restriction angle. That is, the third non-exposed portion C is formed at a position where the first non-exposed portion A and the second non-exposed portion B overlap.

  The restricting protrusion 12 is formed to protrude from the third non-exposed portion C. Thereby, even if the heater main body 2 is rotated in any direction, the regulation protrusion 12 is not exposed. Furthermore, the support protrusion 15 has a portion facing the restriction protrusion 12 regardless of which direction the heater body 2 is rotated.

  According to the pedestal 3 configured in this way, as shown in FIG. 6, even if an uneven load (indicated by an arrow in the figure) is applied to the heater body 2, the heater body 2 is only slightly inclined. Since the support protrusion 15 is in contact with and supported by the restriction protrusion 12, the heater body 2 can be smoothly rotated with a small load applied in the direction intersecting the axis of the rotating shaft 8. In addition, since the support protrusions 15 are provided on the lower surface side of the main body placing plate 6, the support protrusions 15 cannot be seen from the outside, and the appearance of the heater 1 can be prevented from being deteriorated. Further, even if the main body mounting plate 6 rotates while the support protrusion 15 and the restriction protrusion 12 are in contact with each other, the contact area between the support protrusion 15 and the restriction protrusion 12 is small, so that the frictional resistance is small and smooth rotation is achieved. Will not be disturbed. Further, even when the tip of the restriction projection 12 is scratched by the contact between the support protrusion 15 and the restriction protrusion 12, the restriction protrusion 12 is formed so as to protrude from the third non-exposed portion C and cannot be seen from the outside. The appearance of the heater 1 can be prevented from deteriorating. Furthermore, as shown in FIG. 6, even if the power cord 5 enters the gap formed between the base 7 and the main body placing plate 6, it is regulated by the regulating projection 12 and It is possible to prevent intrusion into the vicinity, and to prevent biting by the rotating support protrusion 15.

  In the present embodiment, an example in which the support protrusion 15 and the restriction protrusion 12 are provided so as to face each other is shown, but other than that, although not shown, the restriction protrusion 12 is connected to the outside of the support protrusion 15. You may provide in the position. In this case, the protrusion of the support protrusion 15 is further increased so that the gap with the main pedestal portion 9 is reduced, and the protrusion of the restriction protrusion 12 is increased and the gap with the lower surface of the main body mounting plate 6 is set. Is preferably provided to be small.
