Description
Technical field
The present invention relates to a kind of in the air-supply arrangement of outdoor machine of air conditioner etc. the structure of set fan guard.
Background technology
Generally speaking, in the air-supply arrangement of outdoor machine of air conditioner etc.,, the fan guard (for example, with reference to patent documentation 1～3) of the grid construction that covers the air blow-off outlet is set for the consideration of security and in order to protect blower-use impeller.But fan guard will become the resistance of the air draught that is blown out from the air blow-off outlet.That is, fan guard is a main cause that causes the static pressure rising of pressure fan.The air that blows out from impeller becomes big with the sound that the grid mutual interference mutually of the grid of fan guard is produced, and is increased by the noise level that off-premises station produced.
As Figure 18 and shown in Figure 19, only in the fan guard 9 of the grid construction that constitutes by steel wire a, b, c, d, promptly except air blows out face, the side also be grid construction fan guard 9 (for example, with reference to patent documentation 3) in, this tendency is problem hardly.But, as Figure 13～shown in Figure 17, have the frame wall portion of tubular, and only air blowing out in the fan guard 9 that face is a grid construction (for example, with reference to patent documentation 1,2), the static pressure of pressure fan obviously raises, and produces big noise.The noise of this moment 6 the power (=V that blow out wind speed V
6) expression.
Figure 13～off-premises station device shown in Figure 15 possesses: the shell 1 of the box of growing crosswise, on the front panel 2 of shell 1 set opening 2a, be installed in the top board 8a of the fan guard 9 that the synthetic resin on the front panel 2 makes, the side plate 4,5 that is separately positioned on the shell 1 in Machine Room and the fan room, shell 1 and base plate 8b and set a pair of foot 10 in the mode that covers opening 2a in the bottom of base plate 8b.
In this off-premises station device, if pressure fan is driven, so, and the fan of pressure fan (impeller) rotation, air will be from being inhaled at the set air suction inlet in the back side of shell 1.The air that is inhaled into from air suction inlet is blown towards the place ahead from the opening 2a of shell 1.As Figure 14 and shown in Figure 15, fan guard 9 is the square members that possess at the members of frame of the place ahead that air is blown (shown in Fig. 15 about) tubular that length is outstanding according to the rules.The air that is provided with grid construction at the front surface of fan guard 9 blows out grid 91.Four frame wall 92a～92d of portion that constitute fan guard 9 form by the blind plate that does not have opening.
Therefore, in the fan guard 9 of this structure, as shown in figure 15, when air when the opening 2a of shell 1 and the air by fan guard 9 blow out grid 91 and are blown, fan guard 9 becomes the resistance of air draught, and the static pressure of pressure fan is raise.As a result, the air grid that blows out grid 91 also can increase with the noise level that air mutual interference is mutually produced.
Figure 16 and Figure 17 represent to suck from the side air, and the outdoor machine of air conditioner device of blow out air upward.This off-premises station device possesses the shell 1 of the quadrangular barrel shape of lengthwise.Shell 1 has front 23, a pair of side 24,25 and the back side 22.On the whole surface of the front 23 of shell 1 and the front portion of each side 24,25 form air suction inlet 23a, 24a, the 25a of grid structure respectively.The rear portion of the whole surface at the back side 22 of shell 1 and each side 24,25 forms by blind plate.In shell 1, be provided with and overlook the heat exchanger that is the U word shape, corresponding with air suction inlet 23a, 24a, 25a respectively.
Lower surface at shell 1 is installed base plate 29.Be provided with fan guard 28 cylindraceous on the top of shell 1.The pressure fan (diagram is omitted) that heat exchanger is set in shell 1 and is positioned at the top of heat exchanger.Be provided with end cap 26a flat, square tube shape in the upper end of shell 1.On end cap 26a, be provided with circular open not shown in the figures.Opening installation at end cap 26a is processed into fan guard 28 cylindraceous by pull and stretch.Fan guard 28 under the state that its diameter dwindles slightly than end cap 26a towards above extend.Be provided with the air that possesses grid construction at the upper surface of fan guard 28 and blow out grid 27.
The frame wall 26b of portion and the structure shown in Figure 13～Fig. 15 of fan guard 28 that forms drum is same, is formed by blind plate.Therefore, in this structure, fan guard 9 also still becomes the resistance of the air draught that is blown out from the air blow-off outlet, becomes the main cause that the static pressure that causes pressure fan raises.
In order to address this problem, following this structure has been proposed.For example, according to disclosed structure in patent documentation 4, in the off-premises station of box,, blow out grid blowing out side configuration air at the suction side of propeller fan configuration heat exchanger.In off-premises station, be provided with and blow out the 1st of grid from screw to air and blow out stream and do not blow out grid and arrive the outside the 2nd and blow out stream by air.The air that blows out stream by the 2nd air is by between fan guider and the propeller fan, and the opening that blows out between grid and the fan guider from air is blown to the outside.Like this, the air draught that blows out from propeller fan is divided into flowing through and the 1st blows out the air draught of stream and flow through the 2nd air draught that blows out stream.As a result, to blow out the air capacity of stream corresponding with flowing through the 2nd, and the 1st air capacity that blows out stream of flowing through reduces.Blow out stream from the 1st and blow out the also minimizing thereupon of air capacity that grid is blown towards air.
In addition, in order to solve same problem, following this structure is proposed also.For example, same according to disclosed structure in patent documentation 5, in the off-premises station of box, the most peripheral of fan guard part is along the size of the axially-extending regulation of fan motor.Prolongation at fan guard is provided with otch, so just forms narrow air duct between fan guard and shell.Utilize this air duct, the part of the air-flow of the air that blows out from propeller fan is escaped to circumferencial direction.
But, according to disclosed structure in patent documentation 4, need to form in addition with blow out from propeller fan to air the 1st of grid blow out stream different the 2nd blow out stream.In the case, blow out passage in order to form the 2nd, need implement special Machining of Curved Surface at the edge part that blows out side of fan guider (horn mouth), it is complicated that the 2nd structure that blows out passage becomes.Because more the air of volume is flowed through and the 2nd blown out stream, therefore, also need to be controlled at the 2nd noise that blows out in the stream to be produced.Owing to blow out the big opening of formation between grid and the shell at air, therefore, degraded appearance also needs to improve the installation constitution that air blows out grid.
According to disclosed structure in patent documentation 5, enlarge the width of the circular housing that constitutes fan guard, and, on housing, form the elongated cuts of extending along its circumferencial direction.But if only form otch on housing, so, the static pressure that just can't suppress pressure fan fully raises.Because otch, the rigidity of housing descends, and therefore, fan guard can't be supported fully, easy deformation.Have the off-premises station of air blow-off outlet for the sidewall at shell, if form otch at the whole peripheral part of shell, so, will be short-circuited, the heat exchanger effectiveness of heat exchanger will variation.So-called short circuit is meant, for example under the situation that hot blast blows out from off-premises station when refrigeration, the air that is blown is blocked the phenomenon that is inhaled into once more in the off-premises station because of barrier etc.If this short circuit continues, so, can't utilize off-premises station to implement sufficient heat extraction, therefore, degradation problem under the refrigerating efficiency will appear.

On the frame wall 26b of portion of the fan guard 28 that forms drum, two elongated openings 93 are arranged in parallel along the width of frame wall portion, and, the opening of arranging along width 93 to circumferencial direction along fan guard 28, interval according to the rules is provided with.Therefore, the air of ormal weight is in fan drum 1, and not only the air from fan guard 28 upper surfaces blows out grid 27, and also the opening 93 from the frame wall 26b of portion of fan guard 28 blows out.
Therefore, in this fan guard 28, the air that the pressure fan in shell 1 is blown towards the top blows out grid 27 from the air of fan guard 28 upper surfaces and is blown, and, also from a plurality of openings 93 of the frame wall 26b of portion, be blown.Like this, blow out air capacity, the wind speed reduction that grid 27 blows out from air.Therefore, the static pressure of pressure fan rises and is suppressed, and the grid that blows out grid 27 because of air also can reduce with the noise that mutual interference mutually produced of air.As a result, not only the unnecessary driving load on fan motor reduces, and power consumption also can reduce.Therefore, can realize low noise, energy-conservation air-supply arrangement.
And according to above-mentioned structure, a plurality of openings are set at the position away from the front portion of the front that is short-circuited easily because of the relation with the shape of heat exchanger 11 and two sides.Therefore, according to this structure, not only can avoid the blow out air quilt, and can avoid the decline of heat exchanger effectiveness near air suction inlet 23a, the 24a of heat exchanger 11, the short circuit that 25a sucks.
In addition, according to above-mentioned structure, the frame wall portion of fan guard 28 has the function as the installing frame that blows out tube and shell 1 installation at air.Therefore, the frame wall portion at fan guard 28 forms opening 93 easily.Therefore, do not need special channels configuration.That is, do not need horn mouth formed yet and be used for the shape of steering current, perhaps demarcation strip is processed into the shape of regulation.The frame wall portion of fan guard 28 constitutes the installing frame to end cap 26a, and has very high rigidity, and is therefore, not yielding.
(variation)
In the present embodiment, also can reinforcing rib L shown in Figure 9 be set at each opening 93 places.
