Embodiment
To enable above-mentioned purpose of the present utility model, feature and advantage more obvious understandable, below in conjunction with the accompanying drawings to this
The embodiment of utility model is described in detail.
Referring to Fig.1 and 2, the return air service chamber 100 that the utility model is provided is assembled with fan coil 200, specifically,
Return air service chamber 100 is cuboid, starts several perforates 120 on a side of cuboid, perforate 120 is generally square
Hole, the blower fan 210 and part of fan coil 200 then enter in return air service chamber 100 from the perforate 120 so that both
It is fitted close.
Maintenance door 110 is provided with a side adjacent with the side where perforate 120, maintenance door 110 is examined with return air
Repair case 100 to connect by hinge 113, handle 111 is provided with maintenance door 110, stainless steel can be used to be used as handle 111 and hinge
113 material.If the length of maintenance door 110 is larger, two handles 111 can be symmetrical arranged in the longitudinal direction.
When staff holds handle 111, maintenance door 110 can be driven to be rotated along hinge 113, then staff enters
Entering the inside of maintenance door 110 namely the inside of return air service chamber 100 can overhaul to blower fan 210, thus not necessarily in existing skill
In art, fan coil 200 is overhauled at return air inlet, so that fan coil 200 can be not necessarily mounted near return air inlet.
Finish and make when to the maintenance of fan coil 200, close maintenance door 110, due in return air service chamber 100 air flow compared with
It is many, in order to avoid maintenance door 110 is rushed open by air-flow, then latch 112, the side are provided with a side of maintenance door 110
It is relative with the side where hinge 113.When maintenance door 110 is closed, using latch 112 by maintenance door 110 and return air service chamber
100 fix.When the length of maintenance door 110 is larger, three latches 112 can be symmetrical arranged in the longitudinal direction.Similarly, latch
112 material is selected from stainless steel.
