As illustrated in figure 4f, lug 128 can be slipped into groove 118, thus can easily the top panel 120t of this draft chamber 120 be connected on the top panel 110t of this coil pipe casing 110.After by lug 128 insertion groove 118, the top panel 120t part of this draft chamber 120 is positioned at above the top panel 110t of this coil pipe casing 110.The top panel 120t of this draft chamber 120 also can be supported by this fan panel 131, is appreciated that the supporting provided by this fan panel 131 is optional.Return Figure 1A and 1B, the top panel 120t of this draft chamber 120 also can be supported by the side panel 120a of this draft chamber 120 and 120b.
Use groove 118 and lug 128 can contribute to reducing use screw as far as possible, thus can contribute to reducing as far as possible labour cost and/or the material cost of this indoor set 100 of assembling and/or reduce material cost.In certain embodiments, when the top panel 110t of this coil pipe casing 110 and top panel 120t of this draft chamber 120 is relatively long, the joint of groove 118 and lug 128 may not guarantee firm connection.In these embodiments, one or more screw can be used to strengthen the connection between the top panel 110t of this coil pipe casing 110 and top panel 120t of this draft chamber 120.
Each groove 118 and each coupling lug 128 can contribute to simplifying from the dismounting of this coil pipe casing 110 and/or settle this draft chamber 120.
Be appreciated that in certain embodiments, each groove can be positioned on the top panel of this draft chamber, and each lug can be positioned on the top panel of this coil pipe casing.
Return Figure 1B, by one or more alignment pin 123, this filter 122 is installed in this draft chamber 120.Fig. 5 A to 5F shows the embodiment of each alignment pin 123 and using method thereof.
As shown in Figure 5 A and 5B, each alignment pin 123 is generally configured to the profile with ' L ' shape, and the profile of being somebody's turn to do " L " shape comprises long-armed portion 123a and galianconism portion 123b.This long-armed portion 123a has length L5a, and this galianconism portion has length L5b.
This long-armed portion 123a and this galianconism portion 123b is configured to have the first unci 125a and the second unci 125b respectively.This first and second uncis 125a and 125b and this long-armed portion 123a and this galianconism portion 123b is configured to have installing hole 127.Above-mentioned installing hole can have diameter D5.
As seen in figs. 5c and 5d, alignment pin 123 can be configured to hold relatively thin filter 122a or relatively thick filter 122b.As shown in Figure 5 C, when using relatively thin filter 122a, the first unci 125a of this long-armed portion 123a is configured to the side panel 120a blocking this draft chamber 120.And this galianconism portion 123b is configured to this filter 122a to be maintained at suitable position.As shown in Figure 5 D, when using relatively thick filter 122b, the second unci 125b of this galianconism portion 123b is configured to the side panel 120a blocking this draft chamber 120.And this long-armed portion 123a is configured to this filter 122b to be maintained at suitable position.Had the alignment pin 123 of two arms of different length by configuration, alignment pin 123 can be configured to the filter holding different-thickness.This can contribute to the instrumentation simplifying this HVAC indoor set 100.
As shown in Fig. 5 E and 5F, the first unci 125a of alignment pin 123 or the second unci 125b is configured to the positioning chamber 124 of the side panel 120b blocking this draft chamber 120.Can use pin mounting structure 265 such as self-tapping screw that alignment pin 123 is fixed on positioning chamber 124.
As illustrated in figure 5f, positioning chamber 124 has hole clipping 261, and this hole clipping 261 is configured to engage such as sells mounting structure 265.The hole clipping 261 of positioning chamber 124 can have diameter D6.This diameter D6 can be configured to compared with the diameter D5 in the hole 127 of alignment pin 123 relatively little.This diameter D5 is configured to when in the hole 127 mounting structure 265 being positioned over alignment pin 123, and mounting structure 265 can freely rotate.The hole clipping 261 that this diameter D6 is configured to positioning chamber 124 can block this mounting structure 265.
When settling, when being used pin mounting structure 265 (as self-tapping screw) that alignment pin 123 is fixed on positioning chamber 124 by such as rotary motion, the hole clipping 261 of positioning chamber 124 can block pin mounting structure 265 (bar of such as screw), and alignment pin 123 does not rotate with mounting structure 265.This can contribute to the arrangement by using alignment pin 123 to simplify filter 122.
It is noted that alignment pin 123 also can be configured to block be positioned at the top panel 120t of this draft chamber 120 and/or the cavity of bottom panel 120d.
Positioning chamber 124 can contribute to placing or aim at alignment pin 123 rapidly, thus when unci 125a or 125b blocks positioning chamber 124, can align with the hole clipping 261 of positioning chamber 124 rapidly in the hole 127 of alignment pin 123.Positioning chamber 124 also can provide recess to hold pin mounting structure 265, thus pin mounting structure 265 does not protrude from side panel 120b.When being connected to by ventilation duct on side panel 120b (and/or 120a), the pin mounting structure 265 of recess does not generally disturb ventilation duct to be arranged on side panel 120b (and/or 120a).
For noted earlier, be appreciated that when not departing from the scope of the invention, can modify in detail.Description and described each embodiment are intended to be regarded as be only exemplary, and the broad sense of claims represents the scope and spirit that the present invention is real.
