As shown in fig. 1 and 2, an air deflector 30 is installed at an air outlet of a casing 10 of the floor air conditioner 100, and the air deflector 30 can rotate relative to the casing 10 to open and close the air outlet and adjust an air outlet direction. In the related art, a matching groove is provided at an air outlet section of the scroll casing 21 of the floor air conditioner 100, and when the air deflector 30 rotates to a position for closing the air outlet, a right side of the air deflector 30 contacts with a groove wall of the matching groove. Thus, when the air outlet is closed, no gap is formed between the air deflector 30 and the volute 21, so that the air conditioner is more attractive. However, in the cooling mode of the air conditioner, when the air guide plate 30 is rotated to guide the air to the right, the blown cold air directly impacts the groove wall of the engagement groove, the temperature of the groove wall of the engagement groove is rapidly lowered to easily form condensed water, and the condensed water flows down to the bottom of the cabinet 10 along the groove wall of the engagement groove. When the accumulated water is excessive, the condensed water flows to the ground from the bottom of the cabinet 10.

Specifically, the casing 10 may include a base 13, a pillar extending upward from the base 13, and an air inlet panel 11 and an air outlet panel 12 enclosing the outside of the pillar, where the base 13 and the pillar together form a frame of the floor air conditioner 100 to provide a supporting function for other components of the air conditioner; the air inlet panel 11 and the air outlet panel 12 together form a body of the floor air conditioner 100. Wherein, the air inlet is arranged on the air inlet panel 11, and the air outlet is arranged on the air outlet panel 12.

It should be further noted that the air inlet panel 11 and the air outlet panel 12 are both installed on the base 13, so that there is an assembly gap on the base 13, and therefore when condensed water formed on the air conditioner flows down onto the base 13 and accumulated water on the base 13 is large, the condensed water flows to the ground from the base 13.

Fig. 4 is a schematic structural diagram of an air duct assembly in an embodiment of the present application. Referring to fig. 4, the present embodiment provides an air duct assembly 20, the air duct assembly 20 includes a volute casing 21 and a volute tongue 22, and the volute casing 21 and the volute tongue 22 jointly define an air outlet duct.

Fig. 5 is a schematic view of the connection between the grating and the volute tongue in the embodiment of the present application. As shown in fig. 5, the volute tongue 22 includes a horizontally disposed connecting plate and a volute tongue guiding plate 221 extending vertically along an outer edge of the connecting plate, wherein the connecting plate specifically includes an upper connecting plate 222 and a lower connecting plate 223, the upper connecting plate 222 is connected to a top end of the volute tongue guiding plate 221, the lower connecting plate 223 is connected to a bottom end of the volute tongue guiding plate 221, and the upper connecting plate 222 and the lower connecting plate 223 are located on the same side of the volute tongue guiding plate 221.

Fig. 6 is a schematic structural diagram of a volute in the embodiment of the present application. As shown in fig. 6, the scroll casing 21 includes a top plate 211 disposed horizontally, a scroll casing guide plate 213 formed to extend vertically downward from an outer edge of the top plate 211, and a bottom plate 212 formed to extend horizontally from a bottom end of the scroll casing guide plate 213, and both the top plate 211 and the bottom plate 212 are located on the same side of the scroll casing guide plate 213.

The volute tongue 22 is detachably connected to the volute casing 21, and the volute casing guide plate 213 is opposite to the volute tongue guide plate 221, and the side of the volute casing guide plate 213 facing the volute tongue 22 and the side of the volute tongue guide plate 221 facing the volute casing 21 are used for guiding air, so that air entering the casing 10 from the air inlet flows along the volute casing guide plate 213 and the volute tongue guide plate 221 to guide the air to the air outlet.

The volute tongue 22 and the volute 21 can be detachably connected by screwing or clamping and the like. Illustratively, the upper connecting plate 222 of the volute tongue 22 is connected with the top plate 211 of the volute casing 21 through fastening screws, and the lower connecting plate 223 of the volute tongue 22 is connected with the bottom plate 212 of the volute casing 21 through fastening screws, so that the volute tongue 22 and the volute casing 21 are screwed together.

The volute casing 21 is an air outlet section of the volute casing 21 at a position close to the air outlet, the volute casing 21 is an air inlet section of the volute casing 21 at a position close to the air inlet, and the volute tongue 22 is an air outlet section of the volute tongue 22 at a position close to the air outlet. The distance between the air outlet section of the volute casing 21 and the air outlet section of the volute tongue 22 in the length direction of the floor air conditioner 100 is consistent with the width of the air outlet, so that the air outlet end of the air duct defined by the volute tongue 22 and the volute casing 21 is matched with the air outlet.

FIG. 7 is a schematic view illustrating a connection between an air deflector and an air duct assembly according to an embodiment of the present disclosure. As shown in fig. 7, the floor air conditioner 100 further includes an air deflector 30, a lower connecting plate 223 of the volute tongue 22 is provided with a lower mounting hole, an upper connecting plate 222 is provided with an upper mounting hole, an upper end of the air deflector 30 is rotatably mounted in the upper mounting hole, and a lower end of the air deflector 30 is rotatably mounted in the lower mounting hole. Therefore, the air deflector 30 can rotate relative to the volute tongue 22 to adjust the air after heat exchange to supply air left and right, and the air supply range is expanded.

It can be understood that the height of the air deflector 30 is determined by the distance between the lower connecting plate 223 and the upper connecting plate 222, and the volute tongue 22 is reasonably designed, so that the air deflector 30 mounted on the volute tongue 22 is matched with the air outlet. Specifically, when the air outlet is large, as shown in fig. 7, the height of the air deflector 30 is greater than the height of the volute casing 21, and the lower connecting plate 223 of the volute tongue 22 in the air duct assembly 20 is lower than the bottom plate 212 of the volute casing 21; or, when the air outlet is small, the height of the air deflector 30 may be the same as the height of the scroll casing 21, and the lower connecting plate 223 of the air duct assembly 20 is located at the same height as the bottom plate 212 of the scroll casing 21.

It should be noted that the air outlet section of the volute casing 21 is provided with a matching groove, when the air deflector 30 rotates to close the air outlet, the right side of the air deflector 30 is attached to the groove wall of the matching groove, so that when the air conditioner is not in operation and the air outlet is closed, no gap exists between the air deflector 30 and the volute casing 21, and the appearance is not affected. Specifically, referring to fig. 2, the volute guide plate 213 has a first abutting wall 2130 and a second abutting wall 2131, the first abutting wall 2130 is connected to the windward side surface of the volute guide plate 213, the second abutting wall 2131 is connected to the first abutting wall 2130 with an included angle therebetween, and the first abutting wall 2130 and the second abutting wall 2131 define a fitting groove together. When the air guiding plate 30 rotates to close the outlet, the air guiding plate 30 contacts the first abutting wall 2130 and the second abutting wall 2131. The windward side of the volute guide plate 213 refers to the side of the volute guide plate 213 facing the air duct, and the leeward side of the volute guide plate 213 refers to the side of the volute guide plate 213 facing away from the air duct; the angle between the first abutting wall 2130 and the second abutting wall 2131 is not limited, and is, for example, an obtuse angle in fig. 1 and 2.

FIG. 8 is a first partial schematic view of a lower portion of an air duct assembly according to an embodiment of the present disclosure. In this embodiment, as shown in fig. 8, the edge of the lower connecting plate 223 is provided with a peripheral side wall in an upward protruding manner, and the lower connecting plate 223 and the peripheral side wall together define a water collecting cavity with an open top; the lower part of the matching groove is provided with a water guide groove 2132 which extends from the air outlet section of the volute casing 21 to the air inlet section of the volute casing 21 and extends obliquely downwards, and the tail end of the water guide groove 2132 is positioned above the opening of the water collecting cavity. That is, the water guide groove 2132 is provided at a position of the volute guide plate 213 close to the bottom plate 212.

With such an arrangement, when the air deflector 30 rotates rightwards to guide the air rightwards in the cooling mode of the vertical air conditioner 100, the cold air is blown onto the first abutting wall 2130 and the second abutting wall 2131, so that the temperatures of the first abutting wall 2130 and the second abutting wall 2131 are suddenly reduced to form condensed water, the condensed water flows into the water guide groove 2132 along the first abutting wall 2130 and the second abutting wall 2131, the condensed water gathered in the water guide groove 2132 obliquely flows downwards along the water guide groove 2132, and after reaching the tail end of the water guide groove 2132, at least part of the condensed water flows in the vertical direction and falls into the water collecting cavity, so that the condensed water can be collected, and the condensed water in the matching groove is favorably prevented from falling to the bottom of the casing 10 and flowing to the ground.

The water chute 2132 is described below with reference to the drawings. The water chute 2132 includes, but is not limited to, the following possible implementation manners:

fig. 9 is a partial schematic view of a water chute on a volute according to an embodiment of the present disclosure. In a first possible implementation manner, as shown in fig. 9, a joint of the first abutting wall 2130 and the second abutting wall 2131 forms a vertically extending intersection line, the water guiding gutter 2132 may include a first guiding gutter and a second guiding gutter that are communicated with each other, the first guiding gutter is disposed on the first abutting wall 2130 and extends obliquely downward toward the intersection line, and the second guiding gutter is disposed on the second abutting wall 2131 and extends obliquely downward toward the intersection line. That is, the chute 2132 is substantially "V" shaped, with the ends of the "V" shaped chute 2132 lying on intersecting lines. The angle of the first diversion trench inclined to the intersection line and the angle of the second diversion trench inclined to the intersection line can be the same or different.

In a second possible implementation, the water chute 2132 may extend obliquely downward from the second abutting wall 2131 to the first abutting wall 2130, and the end of the water chute 2132 is located on the first abutting wall 2130. That is, the water chute 2132 in the present embodiment includes a first water guide segment located on the first abutment wall 2130 and a second water guide segment located on the second abutment wall 2131.

Fig. 10 is a partial enlarged view of B in fig. 4. In a third possible implementation, as shown in fig. 10, the water chute 2132 extends obliquely downward from the second abutting wall 2131 to the wind-facing side surface of the volute guide plate 213 via the first abutting wall 2130. That is, the water guide groove 2132 in this embodiment includes a first water guide section located on the first abutting wall 2130, a second water guide section located on the second abutting wall 2131, and a third water guide section 2132a located on the windward side surface of the volute guide plate 213, and the second water guide section, the first water guide section, and the third water guide section 2132a are sequentially communicated, and the end of the water guide groove 2132 is located on the windward side surface of the volute guide plate 213.

It should be noted that, in the second and third realizable manners, the obliquely downward extension of the water chute 2132 does not mean that the angles of the water guiding segments of the water chute 2132 inclined to the intersecting line are the same, so that the slopes of the water chutes 2132 as a whole are completely the same, but it may mean that the water guiding segments of the water chute 2132 have different slopes as long as the water chute 2132 as a whole has a downward inclination.

In the second and third realizable forms, the shape of the water chute 2132 is not limited. For example, in the example shown in fig. 10, when the water guide 2132 extends from the second abutment wall 2131 to the windward side of the volute guide plate 213, the water guide 2132 includes two parallel groove walls and a groove bottom located between the two groove walls, and the groove bottom is an arc surface. That is, the cross section of the water guide groove 2132 in the first direction is "U" shaped. The first direction is perpendicular to the axial direction of the water chute 2132, and the first direction is parallel to the horizontal plane.

For example, the inclination angle of the whole water chute 2132 may be 10 ° to 30 °, specifically, an included angle between the center line of the water chute 2132 and the horizontal plane is 10 ° to 30 °. Accordingly, when the water guide rail 2132 extends from the second abutment wall 2131 to the windward side of the volute guide plate 213 via the first abutment wall 2130, the inclination angles of the first water guide section, the second water guide section, and the third water guide section 2132a of the water guide rail 2132 are all 10 ° to 30 °. Therefore, the inclination angle of the water guide groove 2132 is moderate, and compared with the case that the water guide groove 2132 has a larger inclination angle, the inclination angle is favorable for avoiding the tendency that the condensed water collected in the water guide groove 2132 still flows obliquely downwards after flowing out from the tail end of the water guide groove 2132, thereby being favorable for avoiding the condensed water from flowing obliquely downwards to the bottom plate 212 of the volute casing 21.

The water chute 2132 adopts any one of the three manners, and the volute tongue 22 is required to be arranged so that the opening of the water collection cavity is positioned below the tail end of the water chute 2132 to ensure that the water collection cavity can collect the condensed water.

In the first and second modes, the entire water chute 2132 is only disposed on the matching groove, and the inner surface of a part of the peripheral side wall may be attached to the leeward side surface of the air outlet section of the volute guide plate 213, that is, the air outlet section of the volute guide plate 213 is located inside the peripheral side wall, so that the condensed water in the matching groove can directly flow downward into the water collecting cavity.

In the third mode, that is, when the water chute 2132 extends from the second abutting wall 2131 to the windward side surface of the scroll guide plate 213, as shown in fig. 8, the peripheral side wall may include a peripheral wall 2231 and a connecting wall 2232, the peripheral wall 2231 is disposed at the front side edge of the lower connecting plate 223 and extends upward, the connecting wall 2232 is disposed at the rear side edge of the lower connecting plate 223 and extends upward convexly, a grid mounting plate 2233 is disposed at the top of the connecting wall 2232 so as to protrude inward of the water collecting cavity, the height of the grid mounting plate 2233 is equal to or lower than the height of the bottom plate, and the end of the water chute 2132 is located above the grid mounting plate 2233. Here, the edge of the lower connection plate 223 facing the air outlet panel 12 is a front side edge, and the edge of the lower connection plate 223 facing the air inlet panel 11 is a rear side edge.

A third abutting wall 2234 protruding upward is provided on a side of the grill mounting plate 2233 close to the volute guide plate 213, and the third abutting wall 2234 abuts against a bottom of the air outlet section of the volute guide plate 213. Thus, compared with the first and second modes, the volute guide plate 213 of the present embodiment is abutted against the volute tongue 22, so that the fitting accuracy is higher, and the air duct assembly 20 is more beautiful as a whole. In fig. 8, both the connecting wall 2232 and the surrounding wall 2231 have an arc shape, and both ends of the connecting wall 2232 are connected to both ends of the surrounding wall 2231, respectively.

The floor air conditioner 100 further includes a grill 60, the grill 60 is established on the grill installation plate 2233 in the height direction of the floor air conditioner 100, and the grill 60 is located inside the air guide plate 30. That is, the grill 60 is also disposed within the wind tunnel between the crossflow blower 50 and the air deflection plates 30. When the floor air conditioner 100 is operated, the air in the air duct flows through the grille 60 and is then delivered to the air deflector 30. Through setting up grid 60, grid 60 is used for blockking that the user stretches into the wind channel with the finger from the air outlet in, and then is favorable to avoiding user's finger to be by the fish tail.

It is understood that the projected area of the grating mounting plate 2233 in the vertical direction is smaller than the area of the lower connecting plate 223, the grating mounting plate 2233 cannot completely shield the lower connecting plate 223, so that the top of the water collecting cavity enclosed by the surrounding wall 2231, the connecting wall 2232 and the lower connecting plate 223 is open.

As can be seen from the above, an exemplary flow path of the condensed water in the present embodiment is: the condensed water in the mating groove flows down into the water guide groove 2132 along the first abutting wall 2130 or the second abutting wall 2131, and flows obliquely downward along the water guide groove 2132 until the condensed water flows to the end of the water guide groove 2132; then, at least a part of the condensed water flows out of the water chute 2132 and flows onto the third abutting wall 2234 in the vertical direction under the action of gravity, and the condensed water flows onto the grid mounting plate 2233 through the third abutting wall 2234, and then drops onto the lower connecting plate 223 from the front side edge of the grid mounting plate 2233, and is collected by the water collecting chamber.

Here, the end of the water guide groove 2132 may be spaced apart from the bottom edge of the volute guide plate 213, and at this time, the condensed water flowing out from the end of the water guide groove 2132 flows along the windward side surface of the volute guide plate 213 to the third abutment wall 2234. Alternatively, the end of the water guide groove 2132 is located at the bottom edge of the volute guide plate 213, and at this time, the condensed water flowing out of the end of the water guide groove 2132 flows directly onto the third abutment wall 2234.

With continued reference to fig. 8, when the volute tongue 22 provided with the grille mounting plate 2233 is assembled with the volute casing 21, the rear side surface of the grille mounting plate 2233 is in contact with the front side surface of the bottom plate 212, and since the grille mounting plate 2233 is not higher than the bottom plate, the grille mounting plate 2233 does not protrude into the air duct, so as to prevent the wind resistance of the air duct from increasing. It can be understood that, when the lower connecting plate 223 is lower than the bottom plate 212, the height of the air deflector 30 is greater than that of the volute 21, and the air duct assembly 20 is particularly suitable for the floor air conditioner 100 with a large air outlet.

FIG. 11 is a second partial schematic view of a lower portion of an air duct assembly according to an embodiment of the present disclosure. Further, as shown in fig. 11, the upper surface of the grill mounting plate 2233 is lower than the upper surface of the bottom plate 212. In other words, the upper surface of the bottom plate 212 is higher than the upper surface of the grid mounting plate 2233. Therefore, the front side of the bottom plate 212 facing the air outlet exceeds a part of the upper surface of the grill mounting plate 2233, and the part of the bottom plate 212 exceeding the grill mounting plate 2233 is a blocking surface, which can block the condensed water on the grill mounting plate 2233 from flowing onto the bottom plate 212, so as to prevent the condensed water from flowing into the scroll casing 21.

Further, the height of the grill mounting plate 2233 gradually decreases from one side near the bottom plate 212 to the other side away from the bottom plate 212. That is, the grill mounting plate 2233 is gradually inclined downward from the rear to the front. From this, the upper surface of grid mounting panel 2233 is the inclined plane, and the inclined plane plays the water conservancy diversion effect, and the comdenstion water that falls on grid mounting panel 2233 flows down along the inclined plane and falls into the intracavity that catchments to ensure that the comdenstion water can be collected by the chamber that catchments as far as.

Alternatively, a blocking wall 2235 is protruded upward from the other side of the grill mounting plate 2233 away from the bottom plate 212, and the blocking wall 2235 is provided with a gap through which water flows. In this embodiment, the blocking surfaces of the blocking wall 2235, the grille mounting plate 2233 and the bottom plate 212 define a water receiving tank, and condensed water falls into the water receiving tank and then flows out of the gap, and then falls into the water collecting cavity.

In the third aspect, that is, when the water guide groove 2132 extends from the second abutting wall 2131 to the windward side surface of the volute guide plate 213, the water guide groove 2132 may be formed by the volute guide plate 213 being recessed toward the windward side surface, specifically, the third water guide segment 2132a is formed by the volute guide plate 213 being recessed toward the windward side surface. The third water guide segment 2132a may be formed by a stamping process or may be formed by an integral molding process such as injection molding.

Alternatively, the volute guide plate 213 may be provided with a water guide wall in a protruding manner, and the water guide groove 2132 is defined by the water guide wall and the volute guide plate 213.

Because the protruded water guide wall extends into the air duct to block part of the wind, the present embodiment is preferably implemented by forming the water guide groove 2132 by recessing the wind-facing side surface of the volute guide plate 213, and the water guide groove 2132 does not affect the wind resistance of the air duct.

The water guide groove 2132 may be provided in plural, and the plural water guide grooves 2132 are provided at intervals in the vertical direction. By providing the plurality of water guide grooves 2132, the flow guiding effect on the condensed water in the mating groove is enhanced, so that the condensed water in the mating groove can be guided into the water collection cavity of the volute tongue 22.

On the basis of the above embodiments, as shown in fig. 8 and 11, the air duct assembly 20 according to the embodiment of the present application may further include a drain pipe, the lower connecting plate 223 is provided with a drain hole 2236, the drain hole 2236 is communicated with the drain pipe, and the drain pipe is used for guiding out water in the water collecting cavity to the outside. Therefore, the drain pipe is used for draining the condensed water collected by the water collecting cavity, thereby being beneficial to preventing the condensed water from falling into the machine shell 10 and flowing out to the ground.

Preferably, the lower connecting plate 223 has a height gradually decreasing from the center thereof toward the edge thereof, and the water discharge holes 2236 are disposed near the edge of the lower connecting plate 223. Therefore, the lower connecting plate 223 has a high center and a low edge, so that condensed water accumulated in the water collecting cavity easily flows into the drain hole 2236 along the surface of the lower connecting plate 223 and is drained, thereby ensuring that water in the water collecting cavity is drained.

So far, the technical solutions of the present application have been described in connection with the preferred embodiments shown in the drawings, but it is easily understood by those skilled in the art that the scope of the present application is obviously not limited to these specific embodiments. Equivalent changes or substitutions of related technical features can be made by those skilled in the art without departing from the principle of the present application, and the technical scheme after the changes or substitutions will fall into the protection scope of the present application.
