The utility model divides the lower half of the volute, which is the most difficult to disassemble, into two parts bounded by a fan support plate. Replace the volute tongue with the folded edge of the fan support plate, so that after the screw is unscrewed, the lower half of the volute can be easily pulled out from under the impeller, which includes the fan and the fan support plate, and the fan is installed through the fan support plate In a suitable position, the fan includes a volute, the volute includes a volute tongue, the volute is set as a split structure with the fan support plate as the boundary, the fan support plate is provided with a folded edge as a part of the volute tongue, and the folded edge is closely matched with the volute, This design method is simple in structure. Two folded edges are turned over on the fan support plate, and these two folded edges are used to replace the original volute tongue part at the lower part of the volute. In this way, the volute will not be damaged during disassembly. The obstacle of the volute tongue part in the prior art can easily remove the volute, so as to achieve the purpose of easy disassembly.

Description

Air-supply structure for air-conditioning duct machine

technical field

The utility model relates to an air supply structure, in particular to an air supply structure for an air conditioner air duct machine.

Background technique

In the prior art, the air conditioner generally includes an indoor unit and an outdoor unit, the indoor unit is arranged indoors, and the outdoor unit is arranged outdoors. One of the indoor units commonly used in central air conditioners is called a ducted unit. The air duct unit is generally installed above the ceiling, and an inspection opening of a suitable size will be set on the ceiling below the indoor unit. Due to space constraints, the inspection opening cannot be set too large. Once the indoor unit of the air conditioner fails , It is the most economical and reasonable way to disassemble and assemble directly through the inspection port. This requires that the fan of the air conditioner must be easy to disassemble and assemble. It is best to disassemble the fan directly without disassembling the air conditioner casing and motor. However, because the volute tongue part of the fan volute is generally a raised structure, and the outlet is diffused upwards and downwards, the traditional structure will be hindered by the impeller when it is directly taken down, and the volute passes through the fan support plate Finally, it is difficult to take it out without enough space, so many existing air supply systems are difficult to disassemble in a small space.

Most of the existing air duct machines directly insert the air outlet of the entire volute into the opening of the fan support plate. To disassemble the volute cannot be taken out directly from the air inlet of the air duct machine, but the air duct machine needs to be removed. The fan can be taken out only after the sheet metal and flange of the air inlet are disassembled. The biggest disadvantage of the existing technology is that the volute of the fan will be stuck by the fan support plate and the impeller, and cannot be disassembled directly, which is very unfavorable for maintenance personnel to operate .

Contents of the invention

The utility model overcomes the above-mentioned defects, and divides the lower half of the volute, which is the most difficult to disassemble, into two parts bounded by the fan support plate, and replaces the volute tongue with the folded edge of the fan support plate. In this way, after the screw is unscrewed, The lower half of the volute is easily extracted from under the impeller.

The technical scheme adopted by the air supply mechanism for air-conditioning duct machine of the utility model is: it includes a fan, a fan support plate, the fan is installed in a suitable position through the fan support plate, the fan includes a volute, the volute includes a volute tongue, and the volute A split structure is set with the fan support plate as the boundary, and the fan support plate is provided with a folded edge as a part of the volute tongue, and the folded edge is closely matched with the volute.

The split structure of the volute is divided into the upper part of the volute and the lower part of the volute, and the lower part of the volute is less than half of the whole volute.

This design method is simple in structure. Two folded edges are turned over on the fan support plate, and these two folded edges are used to replace the original volute tongue part at the bottom of the volute. In this way, the volute will not be damaged when disassembling. The obstacle of the volute tongue in the prior art can easily remove the volute, which has achieved the purpose of easy disassembly.

Description of drawings

Fig. 1 is a structural schematic diagram of an air supply mechanism for an air-conditioning duct machine of the present invention.

In the figure, 1-volute upper part, 2-volute lower part, 3-impeller, 4-fan support plate, 5-flange.

Detailed ways

The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

The technical scheme adopted by the air supply mechanism for the air-conditioning duct machine of the utility model is: it includes a fan, a fan support plate 4, the fan is installed in a suitable position through the fan support plate 4, the fan includes a volute, and the volute includes a volute tongue, The volute is set as a split structure with the fan support plate 4 as the boundary, and the fan support plate 4 is provided with a folded edge 5 as a part of the volute tongue, and the volute tongue and the volute are closely matched. The split structure of the volute is divided into an upper part 1 of the volute and a lower part 2 of the volute, and the lower part 2 of the volute is less than half of the whole volute.

After the volute upper part 1 and the volute lower part 2 are fastened together, the outlet is fixed on the fan support plate 4 after passing through the opening on the fan support plate 4 . In this way, the motor is powered on and rotates, driving the impeller 3 to rotate, sucking the air from both sides of the upper part of the volute 1 and the lower part of the volute 2 to do work on it, and then blowing the air out from the outlet through the expansion of the volute, thereby Realize the function of air supply.
