Abstract

(57) [Abstract] [Purpose] To provide a mounting device for a blower that has a small number of parts, is easy to mount, and can reliably absorb vibration. [Structure] The blower 1 is attached to the base 13 by attaching the base 1
By using the elastic support leg 10 that inserts the engaging portion 11 into the engaging hole 15 of the third portion 3 and engages, and the fixing portion 9 that is screwed onto the base 13 by the screw 8. ,
Since the support leg 10 reliably absorbs the vibration of the blower 1, it is possible to prevent the vibration from being transmitted to the base 13 via the fixing portion 9.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a mounting device for a blower used in a combustion appliance such as a fan heater.

[0002]

[Prior art]

 Conventionally, in this type, in order to prevent the vibration of the blower from being transmitted to the base, cushion rubber is attached to the fixing portion by screws, or disclosed in Japanese Utility Model Publication No. 62-43214. As described above, in addition to the above cushion rubber, another spring material is interposed to surely prevent the transmission of vibration.

[0003]

[Problems to be solved by the device]

 By the way, with this conventional type, the size and hardness of the cushion rubber can easily reduce the vibration absorption capacity, and friction can occur between the cushion rubber and the fixing screw, causing screw deficiency. In addition, the number of parts such as cushion rubber and spring material is large, and it is troublesome to install and time consuming, and the cost is also high.

[0004]

[Means for solving problems]

 This invention focuses on this point and solves the above-mentioned drawbacks. In particular, the structure is such that a blower for sucking air and supplying it to a required place is mounted on a base, and the blower is a screw. It is attached by means of a fixing portion to be screwed and an elastic support leg that engages with an engaging hole formed on the base and absorbs vibration.

[0005]

[Action]

 To attach the blower 1, first, the support leg 10 integrally formed with the suction path member 4 made of synthetic resin, which constitutes the suction path of the sheet metal fan casing 3, is fitted into the engagement hole 15 formed in the base 13. After inserting and temporarily fixing the blower 1 by engaging with the locking portion 11 at its tip, the fixing portion 9 similarly integrally formed on the suction passage member 4 is fixed to the base 13 directly with the screw 8. The mounting is completed, and the mounting is extremely easy by the temporary fixing action of the supporting legs 10 and the direct mounting of the bis 8 and the blower 1 is made by the supporting legs 10 made of resin and having elasticity. The vibration of is surely absorbed and prevented from being transmitted to the base 12.

【Example】

 Next, a fan mounting device according to the present invention will be described with reference to a preferred embodiment shown in the drawings. A blower 1 absorbs indoor air and supplies it as combustion air to a combustion unit (not shown). The blower 1 is a flat sheet metal housing for housing a motor unit 2 and a turbo fan (not shown). It is composed of a casing 3.

Reference numeral 4 denotes a synthetic resin of rigidity, heat resistance, scratch resistance, and impact resistance, such as polypropylene, which covers a suction port 5 formed in the center of the bottom of the fan casing 3 and constitutes a suction path reaching the outside of the device. The suction passage member formed by the above is equipped with a detachable suction lid 7 having a filter net 6 at the tip end so as to be exposed to the outside of the instrument, and two screws 8 are provided in the vicinity of the suction lid 7. Is provided with a fixing portion 9 for fixing the blower 1.

Reference numeral 10 denotes a wing-shaped support leg projecting from both sides outward from a substantially central position of the fan casing 3 of the suction passage member 4, which gradually inclines downward toward the outside to provide elastic force. In addition to holding, the tip portion is provided with a locking portion 11 reinforced by three ribs. The fixing portion 9 and the support leg 10 are formed integrally with the suction passage member 4 and are made of synthetic resin. The suction passage member 4 itself is fixed to the bottom of the fan casing 3 with three screws 12. There is.

Reference numeral 13 is a base which is composed of a lower plate for fixing the blower 1, and a screw hole 14 into which a screw 8 for fixing the fixing portion 9 of the blower 1 is screwed, and a locking portion 11 of the support leg 10 penetrate. It is provided with a square engagement hole 15 for sandwiching the base 13 with the support leg 10 by sliding.

Reference numeral 16 denotes an air outlet opening to the side of the motor portion 2 of the fan casing 3, which communicates with an air blow passage made of rubber (not shown) to supply combustion air to the combustion portion. . Reference numeral 17 is a spindle for connecting and driving the motor unit 2 and the fan in the fan casing 3.

Next, the attachment of the blower 1 to the base 13 will be described. First, after the locking portions 11 of the support legs 10 on both sides are inserted into the engagement holes 15, the entire blower 1 is slid backward. For example, as shown in FIG. 3, the base 13 is sandwiched between the locking portion 11 and the support leg 10 to temporarily fix it, and the fixing portion 9 and the screw hole 14 are aligned with each other and the screw 8 is screwed into the blower. The mounting of No. 1 is completed, and is temporarily fixed by the supporting legs 10, so that the mounting is extremely easy.

Further, the support leg 10 is formed to be inclined downward, has elasticity, and is provided at a position symmetrical with the motor portion 2 via the fan casing 3, so that the blower 1 is driven. As shown in FIG. 2, the support leg 10 expands and contracts vertically by elastic force and absorbs it, and does not transmit it to the fixed portion 9 connected to the base 13 by the screw 8. Even if the blower 1 is not provided, it is possible to reliably prevent the vibration of the blower 1 from being transmitted to the base 13.

Further, since the support leg 10 is integrally formed with the suction path member 4, there is no inconvenience such that a separate member for absorbing vibration is provided, the number of parts increases, the mounting becomes complicated, and the cost increases. It is a thing. Furthermore, by mounting the blower 1 with the side of the fan casing 3 facing downward, it can be easily mounted even in a narrow space, that is, below the combustion section, and the overall size of the device can be made compact.

[0014]

[Effect of device]

 In short, the present invention is one in which a blower 1 for sucking air and supplying the air to a required place is mounted on a base 13. The blower 1 has a fixing portion 9 fixed by a screw 8 and a base 13. Since it is attached with the elastic support leg 10 that engages with the engaging hole 15 formed above and absorbs vibration, the vibration when the blower is driven is accurately absorbed by the support leg and transmitted to the base. Since it does not require a separate material such as cushion rubber or spring material, the number of parts is small, and there is a significant effect that it is not bothersome to install and is inexpensive.
