The specific embodiment
Below in conjunction with the description of drawings embodiment of the invention.
At first the general construction of using refrigeration of the present invention and aircondition is described in conjunction with Fig. 6 and 7.
In Fig. 6, label 20 expressions one base plate, vertical (vertically) moulding 8 and 10 and level (laterally) moulding 6 and constitute a cabinet (though lid is housed on these mouldings are housed on the base plate 20, but it is not shown), two Worm compressors 21, a liquid receptacle 22, a gas receiver 23 or the like are contained in the compressor room of this cabinet bottom, unshowned heat exchanger is contained in compressor room top in this cabinet, and an electric appliance control box 24 is positioned at the compressor room upper right side, and its outside plate installs to cashier's office in a shop.In addition, the fan motor 14 of two fans 15 installs on the moulding (level of this cabinet or vertical moulding) through support of motor 1 or 5.According to the present invention, the lattice framing of support of motor installs to obliquely on the moulding of cabinet and constitutes one and makes the vibration of fan be difficult to pass to structure on the moulding of cabinet.Thereby although existing electric appliance control box must be contained in the compressor room, according to the present invention, electric appliance control box can be contained in the compressor room top and make whole refrigeration and aircondition compacter.By the way, the air entry of label 25 expression heat exchangers.
Fig. 7 is the side cutaway view of an example of using refrigeration of the present invention and aircondition, and the inside of cabinet separates with a dividing plate 26 on above-below direction, and compressor 21 or the like is contained in the compressor room of bottom of cabinet.There is a heat exchanger 13 and a vertically arranged heat exchanger 27 that tilts to install dividing plate 26 tops.One end of heat exchanger 13 has a side cover portion as reinforcement to install on the anterior horizontal moulding 6, and an end of heat exchanger 27 has a side cover portion as reinforcement to install on the rear horizontal moulding 7; The lattice framing that is used for supporting the support of motor 1 of a fan installs on the horizontal moulding 6 in front and rear part and 7 obliquely and the vibration that fan is produced is difficult to pass on horizontal moulding and the heat exchanger, thereby reduces the vibration of horizontal moulding and heat exchanger.For example, the dull and stereotyped female cap of each of cabinet (particularly protecgulum) can be designed so that easily that the vibration amplitude of horizontal moulding and heat exchanger all is equal to or less than 100 μ m.By the way, label 16 expression protecgulums (panel), label 28 expression bonnets (panel).
One example of the cabinet of this refrigeration and aircondition is described below in conjunction with Fig. 1-4.By the way, although two fans are housed among these figure, for simplicity's sake, fan and motor are all not shown.
In Fig. 1, support of motor 1 is made of a fan motor installed part 2 and lattice framing 3 and 4, and lattice framing 3 and 4 is parallel to each other but intersect 2 θ angles.The structure of support of motor 5 is identical, and these two support of motors flatly are installed between anterior horizontal moulding 6 and the rear horizontal moulding 7.Although the vibration that fan produces is passed on support of motor 1 and 5, but install on the horizontal moulding 6 in front and rear part and 7 because the lattice framing 3 and 4 of support of motor 1 and 5 intersects 2 θ angles, so the very little component of amplitude is resolved in the i.e. vibration on the fore-and-aft direction of cabinet of plane vibration of cabinet lid.Because the lattice framing 3 and 4 of support of motor 1 and 5 is mutually 2 θ angles, therefore can be connected respectively on the vertical moulding 8,9 of this cabinet and 10 the connecting portion (being the node portion of member) with respect to preceding lateral upright 3 and 4, thereby lattice framing improves the intensity of cabinet, the particularly moulding intensity in the vibration transfer part as the diagonal stay, thereby except reducing to pass to the vibration on the moulding, can effectively reduce the vibration on surface of the front panel of cabinet especially.In addition, support of motor 1 and 5 and the horizontal moulding in front and rear part constitute the such framework of truss and improve the rigidity on the top of cabinet, thereby whole cabinet is not easy to shake.
Fig. 2 illustrates another example of its basic structure cabinet identical with Fig. 1 embodiment.In this embodiment, the anterior horizontal moulding 6 of cabinet is different with rear horizontal moulding 7 installation site in vertical direction, thus support of motor 1 and 5 be not level but downward-sloping forward.And about the fan motor installed part 2 of support of motor 1 and 5, the installed surface of motor is level, and rotating shaft is not tilted thereby fan is installed on it aft-fan.Therefore the structure of the end face of cabinet is not complicated.According to this example, support of motor 1 and 5 lattice framing neither are parallel to each other, and be out-of-level again, thus the vibration of fan resolve into the lattice framing vertical direction on component and the component on the lattice framing direction, thereby reduce to pass to vibration on the front and rear covers of cabinet by lattice framing.
Fig. 3 illustrates the another example of cabinet.According to this example, heat exchanger 13 in the inside that is contained in cabinet with having upwardly sloped front and rear sides, the anterior horizontal moulding 6 that is contained in heat exchanger 13 front upper is configured to install the preceding moulding of support of motor 1 and 5, rear horizontal moulding 7 is different with anterior horizontal moulding 6 installation site in vertical direction, thereby support of motor 1 and 5 turns forward and tiltedly is installed on horizontal moulding 6 in this front portion and the rear horizontal moulding 7.Therefore, the vibration of fan is decomposed by established angle θ on the horizontal direction and the established angle α on the vertical direction, is distributed to the back of cabinet by heat exchanger 13 thereby the oscillating component on the fore-and-aft direction reduces.Thereby the vibration of passing on the front panel of cabinet reduces, thereby anterior moulding can omit maybe and can use light-duty front panel.
Fig. 4 is the right pseudosection of Fig. 3.Fan motor 14 is contained on the support of motor 5, and fan 15 is contained on the fan motor 14.Support of motor 5 is adorned thereon with oblique angle θ, and anterior horizontal moulding 6 is connected with heat exchanger 13, thereby the vibration that fan 15 produces is not directly passed on the front panel 16.And support of motor 5, vertical moulding 12 and heat exchanger 13 constitute truss structures, thereby have improved the rigidity of cabinet on fore-and-aft direction, thereby reduce the vibration on the rear board of cabinet.
By the way, when support of motor 1 and 5 is mounted to when having upwardly sloped front and rear sides shown in Fig. 1-4, before and after support of motor 1 and 5 must firmly be fixed on the horizontal moulding.If the bore of fan 15 is very big, then big, the Heavy Weight of the size of fan motor 14 is quite required great effort during installation, comprises a combination block of support of motor thereby sling with a crane.Therefore, as shown in Figure 5, on the anterior vertical moulding 8 and 10 rotating shaft is housed and is rotatably mounted anterior horizontal moulding 6 or support of motor is pivotally mounted on the horizontal moulding, and be convenient to the loading and unloading of fan motor on the horizontal moulding in front and back.
As mentioned above, according to the present invention, do not used its support parallel to each other but intersect the support of motor of certain angle.Therefore the vibration that produces of fan acts on cabinet and the moulding that lattice framing support of motor is connected non-orthogonally, but resolves into the component propagation, thereby the vibration of the panel of cabinet reduces.
And, because support of motor is mounted to and is having upwardly sloped front and rear sides, therefore fan pass to through the lattice framing of support of motor vibration on the front and back panel of cabinet resolve into equally with horizontal moulding vertical direction on component and the component on the horizontal moulding direction, thereby further reduce to pass to vibration on the front and back panel of cabinet.Particularly,, therefore vibrate the antinode portion that do not pass to horizontal moulding but its node portion because lattice framing is connected to the connecting portion of vertical moulding and horizontal moulding, thus the propagation of constrained vibration.
In addition, because heat exchanger is mounted obliquely within the cabinet, its end is connected on the horizontal moulding of forward-and-rearward of cabinet, so the vibration of fan also is distributed to the back of cabinet, thereby reduces the vibration of front and back panel except being mounted the angle decomposition through heat exchanger.
As mentioned above,, can prevent that the vibration of fan from passing to cashier's office in a shop, thereby noise reduces, thereby, can use high rotating speed, bigbore fan, thereby make refrigeration and control device compacter than existing structure according to the present invention.
