Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a thin and compact hot air generator.

[0002]

2. Description of the Related Art Conventionally, a hot air generator of this type has a structure as shown in FIGS. That is, inside the outer case 1, a heater cover 3 for holding the heater 2,
It is composed of a fan 5 that rotates at a high speed by a motor 4, and a fan case 6 that surrounds the motor 4 and the fan 5 and that has a substantially spiral shape and guides the air blown from the fan 5 to the heater 2. Energization (heat generation) to the heater 2 At this time, the fan 5 blows air so that warm air is discharged to the leeward side of the heater 2.

[0003]

However, in the conventional structure as described above, the fan case 6 surrounds the motor 4 and the fan 5, and the warm air generator is a separate component from the outer case 1. The thickness direction of the fan case 6 is increased by the thickness of the fan case 6, and as shown in FIG. 6, a substantially circular hole 7 is formed so that the fan case 6 fits into the outer case 1. For this reason, the strength around the hole 7 of the outer case 1 is weak, and the height at the hand (generally about 6 mm) that may occur during use.
The outer case 1 may be destroyed when it falls from 0 cm) to the floor. As a countermeasure against this, a reinforcing rib around the hole 7 was also examined, but there was a problem that the air supply capability was lowered and the wiring process was inconvenient due to the purpose of being particularly thin.

Therefore, the present invention eliminates the need for reinforcing ribs,
The purpose is to obtain a strong and thin hot air generator.

[0005]

In order to achieve the above object, the hot air generator of the present invention comprises a motor, a fan rotated by the motor, and a support plate for supporting and fixing the fan and the motor. A heater that receives the air blown by the fan and emits warm air, a substantially spiral fan case that guides the air blown by the fan to the heater, and a heater cover that holds the heater are provided, and the fan case is an outer casing of the main body. It is formed by integral molding, and the support plate is attached to the opening of the main body contour forming the fan case and is integrated with the main body contour.

[0006]

According to the present invention, since the fan case is formed integrally with the outer casing of the main body and the supporting plate is attached inside the opening forming the fan case of the outer casing and integrated with the outer casing of the main body, the present invention has the above-mentioned structure. A thin and strong main body contour can be obtained.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the warm air generator of the present invention will be described below with reference to the drawings. In FIG. 1, reference numeral 8 is an outer casing of the main body, 9 is an outer rotor motor in which a shaft 10 is caulked to a support plate 11, and a fan 12 is attached to the periphery of the motor 9, and the fan 12 is driven by the motor 9 at a high speed. Rotate. Reference numeral 13 denotes a substantially spiral fan case integrally formed with the main body outer case 8 that covers the motor 9 and the fan 12. Reference numeral 14 is a heater cover that holds a heater 15 that receives the air blown from the fan 12, and the opening on the leeward side faces the outside of the main body outer case 8. Reference numeral 17 is a power cord. The front plate 18 is finally attached, and a replaceable filter 19 is set.

FIG. 2 is a sectional view of this embodiment of the invention. The drawing shows the completion of the assembly, and the support plate 11 is fitted and attached to the fan case 13 formed integrally with the main body outer case 8 at the same position as the outer surface of the main body outer case 8.

FIG. 3 shows a commercialized embodiment using the warm air generator of the present invention. The thin and compact warm air generator of this embodiment is attached to the side surface of the bed 20 so that the hot air outlet is on the upper side, that is, along the side surface of the bed 20,
On the bed mattress 21, a bag 22 for inflating warm air is provided to dry the futon or the bed mattress 21.
It was used as a heating device.

Next, the operation of the structure of this embodiment will be described. A fan that rotates at a high speed by the motor 9 supplies the air, which has passed through the filter 19 and is free of dust and the like, into the fan case 13 and is blown to the heater 15. At this time, the heater 15
When electricity is supplied to the heater 15, warm air is discharged to the leeward side of the heater 15. A fan case 1 having a substantially spiral shape in the warm air generator
3 is integrally molded with the outer casing 8 of the main body, and further the support plate 11
By assembling the fan case 13 in the opening, the support plate 11 and the main body outer case 8 do not overlap with each other and can be made thin, and a wall forming the fan case 13 stands in the hole around the opening. Since the area around the opening is strongly reinforced, it is not necessary to newly provide a reinforcing rib or the like.

Further, when the bed is attached to the side surface of the bed 20, assuming that the thickness of a typical futon on the bed mattress 21 is 5 cm, the thickness of less than that thickness is ideal for the bed 20 to fit into the bed, which is ideal. It is most suitable for such commercialization. By the way, in the case of a hot air generator with a thickness of 4 cm, the reduction of the wall pressure of 3 mm (of the main body outer case) is close to 10% of the total thickness, and the influence is extremely high.

Further, since the fan case 13 is formed integrally with the main body outer case 8 and the support plate 11 for supporting and fixing the motor 9 has a plate shape, the vibration width generated from the motor 9 and the fan 12 is spread and transmitted. Can be made smaller, which is effective in reducing noise.

[0013]

As described in the above embodiments, according to the warm air generator of the present invention, the main body outer casing is formed by integrally molding the fan case, and the support plate forms a part of the main body outer casing. By doing so, the outer casing of the main body and the support plate are fitted at the same surface position, and ribs for reinforcement are not required, so there is no problem of air supply, wiring processing, etc. A wind generator is obtained.

Further, as shown in the embodiment of commercialization in which the warm air generator of the present invention is fixed to the side surface of a bed as a bed drying apparatus for bedding, it has a thinner thickness and a high practical value.
