The hollow chamber is provided with a volute fan assembly structure and is mainly composed of a mounting plate 4 and a plurality of volute fans. The specific structure is described in detail below. The volute fan assembly structure is disposed in the hollow chamber along the longitudinal direction, and the volute is provided on the front side of the mounting plate 4 and on the opposite side of the front panel 51. The mounting plate 4 divides the hollow chamber into two separate sections and the space between the rear and back panels of the mounting plate 4 is connected to an air intake duct 57 are formed. As a preferred solution, the air intake duct 57 is further provided with a heat exchange mechanism such as an evaporator. The space between the front of the mounting plate 4 and the front panel 51 forms the body air duct 56 of the air conditioner. The main body air duct 56 is connected to the upper air outlet 53 and the lower air outlet 54, respectively. In a position corresponding to the volute mounting location, the mounting plate 4 has a mounting plate air inlet opposite the position of the volute air inlet. The volute air outlet is connected to the body air duct (56). When the air conditioner is in operation, air passes through the air intake grille on the rear panel 55 and then into the suction duct 57, then through the mounting plate air inlet and into the volute air outlet, Is accelerated by the centrifugal fan and then passes through the volute air outlet to the body air duct 56 and then moves downward in the body air duct 56 to be discharged by the lower air outlet 54, / RTI > and / or the upper air outlet 53, as shown in FIG.

  A volute fan assembly structure of the present invention includes a mounting plate and at least three volute fans mounted on the front side of the mounting plate. At least three of the volute fans include an upper volute fan with an air outlet disposed at an upper portion and discharging air upwardly, and a lower volute fan with an air outlet disposed below and discharging air downwardly, Further comprising at least one intermediate volute fan between the upper and lower mandrel fans. Wherein the at least one intermediate fan includes at least one bidirectional volute fan having a bidirectional air outlet capable of simultaneously blowing air upward and downward, wherein the bidirectional air outlet and the volute fan adjacent to the bidirectional volute fan are movable in a forward and backward direction And arranged in a zigzag manner. The at least one intermediate volute fan can be a combination of a two-way volute fan and a volute fan blowing in one direction, and can also be a fully two-way volute fan. The bidirectional blower and the volute fan adjacent to the bidirectional volute fan are staggered in the forward and backward directions. In this case, the balun fans can be staggered in the forward and backward directions. In addition, the bidirectional air outlet can blow the air obliquely, Includes a combination of one or two approaches. The specific structure is described in detail below.

Next, referring to Figs. 3 to 18 as an example, the present invention will be described in detail. As shown in Figs. 5 to 7, the volute fan assembly structure includes the mounting plate 4 as well as three volute fans (hereinafter simply referred to as fans). The three volute fans include a first volute fan 1 provided at the top of the mounting plate 4, a third volute fan 3 disposed at the bottom of the mounting plate 4, 1 mounted on the mounting plate 4 and a second ferrite fan 2 disposed on the mounting plate 4 and disposed between the third ferrite fan 3 and the third ferrite fan 3. Wherein the first volute fan (1) has a first volute fan air outlet (18) for blowing air up; The third volute fan has a third volute fan air outlet 39 for blowing air down; The second vault fan has two air outlets, the first air outlet 28 of the second vault fan blows air upwards, and the second air outlet 29 of the second vault fan blows air downward Lt; / RTI > It should be noted that although the mounting plate in this embodiment is provided longitudinally and the three volute fans are also arranged lengthwise, the technical solution of the present invention is not proposed in a longitudinally mounted mounting plate structure have. It is also possible to use horizontal or inclined mounting plates. The definitions of longitudinal, transverse, and longitudinal directions mentioned in the text are all relative to the mounting plate.

The second vesicular fan 2 is disposed between the first and third vesicular fans 1 and 3, and the air outlet is provided in such a manner as to blow air in the longitudinal direction. When mounted on the same plane according to the conventional method of the three fans, the volute of the first and the third ves- sel fins (1) and (3) , Which prevents the air blown by the second (2) volute fan (2) from flowing smoothly into the body air duct (56). Thus, the three fans are provided in a spatially staggered configuration so that the first air outlet 28 of the second and second vena dulse fans are connected to the first and second air outlet 28 of the first and second vena fuels, And the position of the third ferrite fan (3). The influence on the blowing of the second boom lift fan 2 by the first and second boom boats 1 and 3 is minimized as much as possible and for example, And / or in the width direction.

In a preferred embodiment, as shown in Figure 6, the three fans use a staggered arrangement. Specifically, the mounting position of the second mandrel fan 2 on the mounting plate 4 is disposed in front of the mounting position of the third mandrel fans. For example, the second (2) volute fan (2) is disposed closer to the main body air duct (56) than the position where the first and third balun fans (1) and (3) The air blown by the second distillation fan 2 can at least partly avoid the disturbance of the volute of the first distillation column 1 and of the third distillation column 3 of the third distillation column 3, And moves more smoothly through the duct (56). Preferably, the shape of the mounting plate 4 is changed such that the mounting position of the second mandrel fan 2 on the mounting plate 4 is disposed on the front face of the mounting position of the second and third varicap fans . 6 to 8, the mounting plate has a first fan mounting portion 41, a second fan mounting portion 42, and a third fan mounting portion 43. As shown in FIGS. A step is formed between the second fan mounting portion 42 and the first fan mounting portion 41 and the third fan mounting portion 43 so that the second fan mounting portion 42 is mounted on the first fan mounting portion 42. [ (41) and the third fan mounting portion (43) so as to face the front panel (51). In this way, when the three fans are mounted on the mounting plate 4 without changing the shape of the three fans, the mounting position of the second balunts fan 2 on the mounting plate 4 becomes the first and third It may be allowed to be located in front of the mounting position of the volute fan. The merit of shifting in the anteroposterior direction merely increases the thickness to some extent in the anteroposterior direction and has a very small effect on the overall size of the air conditioner without increasing the thickness of the volute fan assembly in the width direction. In a preferred manner, the first air outlet 28 of the second vault fan and the rear wall of the second air outlet 29 of the second vault fan have a plane parallel to the mounting plate, And an inner surface which does not intersect with the volutes of the Vullet fan 1 and the third Vulse fan 3, respectively. In this way, the air blown by the second volute fan 2 may not be blown into the volute of the first and third volute fans 1 and 3, The influence of the blowing of the second boom lift fan 2 by the first and third baluns 1 and 3 is minimized.

Further, the present invention can be used in a manner (not shown) in which three fans are arranged shifted in the width direction. For example, the second volute fan 2 is disposed on the left or right side of the first and second volute fans 1 and 3, It is possible to reduce the disturbance of the blowing of the second distillate fan by the lute fan 3. However, this approach can greatly increase the width of the volute fan assembly in the width direction, which is undesirable in the overall layout of the air conditioner.

In another preferred embodiment, the first air outlet 28 and outlet 28 of the second vaulted fan and the second air outlet 29 of the second vestibule fan are also connected to the bevel of the second vestibule fan 2 It can be arranged obliquely with respect to the lute. 3 to 6, in the actual installation state, the volute of the second vestibule fan 2 is arranged in a manner substantially parallel to the plane of the second vestibule fan mounting portion 42 of the mounting plate 4 Respectively. As shown in Fig. 3, the volute plane of the second vestibule fan 2 extends considerably along the length direction. The first air outlet 28 of the second vault fan and the second air outlet 29 of the second vault fan are moved from the mounting plate 4 to the front panel 51 As shown in Fig. Specifically, the first air outlet 28 of the second vault fan is arranged to blow the air upward in the front direction, and the second air outlet 29 of the second vault fan blows air in the front downward direction . Referring to Figures 6, 10, and 11, the first air outlet 28 of the second varicule is located on the inner side of the rear wall of the first air outlet of the second vault fan adjacent to the second fan mounting portion 42 282 and an inner surface 281 of the front wall of the first air outlet of the second vault fan adjacent to the front panel 51. The inner surface 281 of the front wall of the first air outlet of the second vaulted fan may have a slope or camber and may include an extension line 2811 to the tangent of the slope or camber, 4 forms a first inclination angle? 1; The inner wall 282 of the rear wall of the first air outlet of the second vault fan may have a slope or a camber and the extension line 2821 to the tangent of the slope or camber and the plane of the mounting plate 4 may be the second The inclination angle [theta] 2 is formed. The first inclination angle [theta] 1 may be equal to or different from the second inclination angle [theta] 2. The second air outlet 29 of the second vaulted fan has an inner surface 292 of the rear wall of the second air outlet of the second vault fan adjacent to the second fan mounting portion 42, And an inner surface (291) of the front wall of the second air outlet of the second vault fan adjacent to the second air outlet. The inner surface 291 of the front wall of the first air outlet of the second vaulted fan may have a slope or camber and the tangential direction 2911 of the slope or camber and the plane of the mounting plate 4 may have a third inclination angle (3); The inner surface 292 of the rear wall of the second air outlet of the second vaulted fan may have a slope or camber and the tangential direction 2921 of the camber and the plane of the mounting plate 4 may have a fourth inclination angle? ). The third inclination angle 3 may be the same as or different from the fourth inclination angle 4. Preferably, the extension of the slope or the extension line 2821 of the camber tangent to the inner surface 282 of the rear wall of the first air outlet of the second varicap fan is connected to the first varicap fan 1 ) ≪ / RTI > The extension line of the slope or the extension line 2921 of the camber tangent to the inner surface 292 of the rear wall of the second air outlet of the second vault fan does not intersect with the volute of the third vestibule fan 1 city). Specifically, it means that the region on the extension line of the slope in the front-rear direction or the extension line 2821 of the camber tangent overlapping the protruding portion of the volute on the position plate is disposed on the front surface of the volute. By this arrangement, the air blown by the first air outlet 28 of the second and second boil-lined fans and the second air outlet 29 of the second boil- It is possible to prevent the air from being blown into the volute of the lute fan 3 and to prevent the air from blowing out of the air blowing air of the second balun 5 by the volute of the first and second vat Disturbance can be reduced.

In another preferred embodiment, a combination of the zigzag schemes described above is applied. 3 to 7, the mounting plate has a first fan mounting portion 41, a second fan mounting portion 42 and a third fan mounting portion 43, and the second fan mounting portion 42 And the second fan mounting portion 42 is formed between the first fan mounting portion 41 and the third fan mounting portion 43 and the second fan mounting portion 42 is formed between the first fan mounting portion 41 and the third fan mounting portion 43, And protrudes forward toward the front panel 51 with respect to the fan mounting portion 43. At the same time, the first air outlet 28 of the second volute fan and the second air outlet 29 of the second volute fan can be arranged obliquely with respect to the volute. In other words, it is inclined in the extending direction (that is, the front-rear direction) toward the front panel 51 from the mounting plate 4 in the direction away from the volute. Preferably, the extension line of the slope with respect to the inner surface 282 of the rear wall of the first air outlet of the second vault fan, or the extension line 2821 of the tangent of the camber, 1) does not intersect with the volute. The extension line of the slope with respect to the inner surface 292 of the rear wall of the second air outlet of the second var- uit fan and the extension line 2921 of the tangent of the camber do not intersect with the volute of the third var- The combination of the zigzag manner as described above can reduce an increase in the thickness (back-and-forth direction) of the volute fan assembly structure caused by the staggered points in the forward and backward directions. At the same time, the inclination angle of the first air outlet 28 of the second vena fuant fan to the volute of the second air outlet 29 of the second vena fuant fan can be prevented from becoming large enough to affect the air blowing of the volute fan And the size of the volute fan assembly structure in the thickness direction (front-back direction) and the width (width direction) are not significantly increased, and an optimized design of the entire structure of the air conditioner is realized. At the same time, since the disturbance of the air blowing of the second balunted fan by the first and third balun fans is very small, the air blown by the three fans can smoothly move into the body air duct 56 have.

Another preferred method is to provide a deflector in the first air outlet 28 of the second volute fan and / or the second air outlet 29 of the second volute fan, which are disposed obliquely to the second volute fan have. 12, the upper deflector 280 is provided at the first air outlet 28 of the second varuta fan and the lower deflector 290 is provided at the second air outlet 29 of the second varuta fan, Respectively. The upper deflector 280 is disposed at a position adjacent to the front wall of the first air outlet 28 of the second varicap fan, that is, the front panel 51; The lower deflector 290 is disposed at least in a position adjacent to the front wall of the second air outlet 29 of the second vault fan, that is, the front panel 51. The upper deflector 280 and the lower deflector 290 extend generally in a manner parallel to the mounting plate 4 and / or the front panel 51, i. Preferably, the upper deflector 280 and the lower deflector 290 are provided in the first air outlet 28 of the second vaulted fan and the second air outlet 29 of the second vaulted fan, And a sleeve structure mainly extending. In this way, air blown by the upper air outlet 28 and the lower air outlet 29, in order to reduce the disturbance of the air flow in the main body air duct 56 by reflection of the air flow of the front panel 51, And flows into the main body air duct 56 in a direction substantially parallel to the main body air duct 56. This makes the air flow in the main body air duct 56 more smooth and reduces energy loss. At the same time, when one of the upper air outlet 53 and the lower air outlet 54 is closed as shown in FIG. 3B, for example, the lower air outlet 54 is closed. At this time, the air blown downward by the second air outlet 29 of the second vault fan and the air outlet 39 of the third vault fan is changed to the lower end of the main air duct 56 Not only the flow path between the volute of the second varuta fan 2 and the front panel 51 but also the third varuta fan 3 moves toward the upper air outlet 53. The lower deflector is provided so that air blown downward by the lower air outlet is substantially parallel to the main air duct 56 and the air flow between the volute of the second volute fan 2 and the front panel 51 The air that has been converted from the lower side can smoothly move upward without being disturbed by the air blown by the lower air outlet 29. The lower deflector 290 is not installed and the air blown from the downwardly inclined lower air outlet 29 can cause a barrier against the lower switched air and the directionally changed air smoothly moves upward I can not. Similarly, when the upper air outlet 53 is closed, the effect produced by the upper deflector 280 is applied to the upper deflector 280 in the same manner as the effect produced by the lower deflector 290.

Preferably, the distance from the outer wall of the peripheral wall of the volute adjacent to the centerline 139 of the volute in the direction of the axis 111 to the axis 111 is greater than the distance of the peripheral wall of the volute from both sides of the axis 111 Is greater than the distance from the outer wall to the shaft 111, and the difference is H1 (not shown). Preferably, the outer wall of the peripheral wall of the volute has a cross-section that can be an arc, a trapezoid, a trimmed arc, a triangle or other polygon. The outer wall of the peripheral wall of the volute may be designed as an intermediate protruding structure, for example, to another vertical air conditioner structure having a curved housing. Moreover, since the peripheral wall of the volute has a generally constant thickness, the protrusion of the outer wall of the peripheral wall allows the inner wall of the peripheral wall to have a protruding structure. Comparing the volute in which the peripheral wall is perpendicular to the side wall increases the internal volume of the volute and improves the blowing ability of the volute fan.

For ease of manufacture, the volute may have a split structure. 13 to 15, the volute includes a first half 13 and a second half 15.
