Description

Technical Field

[0001] The invention relates to the technical field of volutes, and in particular to a quick-detachable fan installation structure for a stove. Background Art

[0002] The centrifugal fan in the stove is usually fastened in the bellows by screws, that is, the volute of the centrifugal fan is fastened in the bellows. The volute is usually fixed in the bellows in two ways. One is the single-sided fixing method, that is, fixing one side of the volute on the crossbeam of the bellows. Although this fixing method is simple and convenient, it is not very firm. When the fan is running, the volute is easy to vibrate, thereby increasing the noise of the whole machine; the second is the double-sided fixing method, that is, fixing the two sides of the volute on the two side beams of the bellows respectively. This will increase the number of crossbeams and the number of fixing screws, thereby increasing the difficulty of disassembling the volute. Summary of the invention

[0003] The object of the present invention is to provide a quick-detachable fan installation structure for a stove, which is not only easy to disassemble the volute, but also can reduce vibration and noise.

[0004] The purpose of the present invention is achieved by providing the following technical solutions:

[0005] The present invention provides a quick-detachable fan installation structure for a stove, comprising a fixing boss arranged on the inner side wall of a bellows, in which the fan is installed; and also comprising a fixing plate installed on the outer ring surface of a volute of the fan, wherein the end of the fixing plate rests on the fixing boss and is fixedly connected thereto, a shock-absorbing block is inserted between the bottom of the air outlet of the volute and the bottom wall of the bellows, and the fixing plate and the shock-absorbing block are respectively located on both sides of the volute.

[0006] Preferably, the shock absorbing block is wedge-shaped, and the head of the wedge-shaped shock absorbing block is inserted between the bottom of the air outlet of the volute and the bottom wall of the bellows.

[0007] Preferably, the minimum gap between the volute and the bottom wall of the bellows is located between the air outlet of the volute and the fixing plate.

[0008] Preferably, a shock-absorbing plate is provided between the fixing plate and the fixing boss, and the shock-absorbing plate is fixed to the side wall of the bellows.

[0009] Preferably, at least one side edge of the shock absorbing plate is bent downward to form a supporting portion abutting against the fixing boss, and at least another side edge of the shock absorbing plate is bent upward to form a fixing portion fixed to the inner wall of the bellows.

[0010] Preferably, one side edge of the shock absorbing plate is bent upward to form the fixing portion, and the other side edge of the shock absorbing plate is bent downward to form the supporting portion.

[0011] Preferably, the fixing boss is formed by the inner side wall of the bellows protruding toward the inside of the bellows.

[0012] Preferably, the fixing plate is provided with a handle for facilitating carrying of the fan.

[0013] Preferably, the fixing plate is located at an upper end portion of one side of the volute, and the shock absorbing block is located at a lower end portion of a corresponding side of the volute.

[0014] Preferably, the bellows is provided with an air outlet, and the air outlet of the volute is connected to the air outlet via an air outlet adapter.

[0015] The beneficial effects of the present invention are:

[0016] The present invention provides a quick-detachable fan installation structure for a stove. A fixing boss and a fixing plate are provided so that the end of the fixing plate is placed on the fixing boss and fixedly connected thereto, thereby completing the single-sided fixing of a volute and a bellows. A shock-absorbing block is inserted between the bottom of the air outlet of the volute and the bottom wall of the bellows, and the fixing plate and the shock-absorbing block are respectively located on both sides of the volute, so that the shock-absorbing block completes the support for the other side of the volute. In this way, not only can the volute of the fan be stably fixed, the vibration of the volute is reduced, thereby reducing the noise of the whole machine, but also because the shock-absorbing block is filled between the bottom of the air outlet of the volute and the bottom wall of the bellows, compared with the existing double-sided fixing with screws, the installation structure of the present invention is more convenient and quick to disassemble and install.

[0028] The present invention is further described in conjunction with the following examples.

[0029] A quick-detachable fan installation structure for a stove according to the present invention is as follows: Figure 1 As shown, the fan is installed in the bellows 1, and the fan includes a volute 2, in which a motor 3 and an impeller 4 are installed, and the motor 3 and the electric impeller 4 rotate to generate wind. The quick-detachable fan installation structure includes a fixed boss 11 provided on the inner side wall of the bellows 1, and the fixed boss 11 is formed by the inner side wall of the bellows 1 protruding toward the inside and outside of the box. The quick-detachable fan installation structure also includes a fixing plate 5 installed on the outer annular surface of the volute 2 of the fan, and the fixing plate 5 is located at the upper end of the right side of the volute 2. The end of the fixing plate 5 is placed on the fixing boss 11, and the fixing plate 5 and the fixing boss 11 are fixedly connected by screws.

[0030] The present invention sets a fixing boss 11 and a fixing plate 5, so that the end of the fixing plate 5 is placed on the fixing boss 11 and fixed thereto, thereby completing the fixing of the volute 2 and the right side of the bellows 1; and then by inserting a shock-absorbing block 6 between the bottom of the air outlet 21 of the volute 2 and the bottom wall of the bellows 1, the shock-absorbing block 6 is located at the lower end of the left side of the volute 2, so that the shock-absorbing block 6 completes the support of the left side of the volute 2. Since the fixing plate 5 and the shock-absorbing block 6 are respectively located on both sides of the volute 2, and are approximately symmetrical about the center of the volute 2, this can not only more stably fix the volute 2 of the fan, reduce the vibration of the volute 2, and thus reduce the noise of the whole machine, but also because the shock-absorbing block 6 is filled between the bottom of the air outlet 21 of the volute 2 and the bottom wall of the bellows 1, compared with the existing bilateral fixing with screws, the installation structure of the present invention is more convenient and quick to disassemble and install.

[0031] like Figure 1 As shown, the minimum gap between the volute 2 and the bottom wall of the bellows 1 is located between the air outlet 21 of the volute 2 and the fixing plate 5. The shock absorbing block 6 is wedge-shaped, and the head of the wedge-shaped shock absorbing block 6 is inserted between the bottom of the air outlet 21 of the volute 2 and the bottom wall of the bellows 1, thereby completing the fixing of the left side of the volute 2.

[0032] like Figure 1 As shown, an exhaust port 12 is provided on the left side of the bellows 1, and the air outlet 21 of the volute 2 is connected to the exhaust port 12 through an air outlet adapter 7. A sealing ring is provided between the air outlet adapter 7 and the air outlet 21 of the volute 2 to prevent the air in the volute 2 from leaking.

[0033] like Figure 1As shown, the fixing plate 5 is provided with a handle 51 for conveniently carrying the fan. In order to reduce the vibration transmitted from the volute 2 to the bellows 1, a shock-absorbing plate 8 is provided between the fixing plate 5 and the fixing boss 11. The right edge of the shock-absorbing plate 8 is bent upward to form a fixing portion 82 fixed to the inner side wall of the bellows 1. The front and rear side edges and the left side edge of the shock-absorbing plate 8 are bent downward to form a supporting portion 81 abutting against the fixing boss 11.

[0034] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention, rather than to limit the scope of protection of the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the present invention.
