The indoor unit of a floor type air conditioner according to an embodiment of the present invention may generally include a case 10, an air duct 20, and a guide 30. The casing 10 has a first air blowing port 11, and the first air blowing port 11 is used for blowing an air flow in the casing 10 into a room to condition indoor air. The air flow can be cold air produced by the indoor unit of the vertical air conditioner in a refrigeration mode, hot air produced in a heating mode, fresh air in a fresh air mode and the like. The number of the first blowing ports 11 may be one or more. An air duct 20 is provided in the housing 10, and has an air inlet 23 and a first air outlet 21 facing the first air blowing port 11, for guiding the air flow in the housing 10 to the first air blowing port 11. The flow guide member 30 is arranged in the air duct 20 and has a hollow structure, the front surface of the flow guide member is provided with air outlet holes 34 at intervals, and the rear surface of the flow guide member is provided with air inlet holes (not numbered in the figure); one end of the flow guiding element 30 is close to the first air outlet 21 and defines an air outlet gap 25 with the air duct 20, the air flow in the casing 10 reaches the first air outlet 21 through the air outlet gap 25, the other end of the flow guiding element 30 is communicated with the outside of the casing 10, and the air outside the casing 10 flows into the flow guiding element 30 through the air inlet and flows out of the flow guiding element 30 from the air outlet 34 to reach the first air outlet 21. In the present invention, the air outside the casing 10 may be indoor air, or may be air of outdoor environment (in this case, it is equivalent to introduce fresh air), or may be air including indoor air and outdoor environment. In the vertical air conditioner indoor unit provided by the embodiment of the invention, the air duct 20 is internally provided with the flow guide piece 30, the flow guide piece 30 is of a hollow structure, the front surface is provided with air outlet holes 34 at intervals, and the rear surface is provided with air inlet holes; one end of the flow guide member 30 is close to the first air outlet 21 and defines an air outlet gap 25 with the air duct 20, the air flow in the casing 10 reaches the first air outlet 21 through the air outlet gap 25, the other end of the flow guide member 30 is communicated with the outside of the casing 10, the air outside the casing 10 flows into the flow guide member 30 through the air inlet and flows out of the flow guide member 30 from the air outlet 34 to reach the first air outlet 21, so that the air flow blown out from the first air outlet 21 to the first air supply outlet 11 is formed by mixing two air flows from different sources, the difference between the air outlet temperature and the room temperature is reduced, the air flow of the first air supply outlet 11 is prevented from being too cold or too hot, the air outlet is more comfortable, and a user can feel a comfortable blowing feeling of being cool but not cold in the cooling mode. Generally, a plurality of air outlets 34 are formed on the front surface of the flow guide element 30 at regular intervals, and the air outlet can be more uniform through a dense porous design. One or more air intakes may be provided on the housing 10 to allow air to enter the housing 10 through the air intakes. As shown in fig. 5, the housing 10 may be formed by combining a front cabinet 101 and a rear cabinet 102.
Since the indoor unit of the floor type air conditioner is generally disposed with the rear side thereof being close to the wall, it is required to have a stronger forward blowing capability. Therefore, in some embodiments of the present invention, as shown in fig. 1 to 4, the first air blowing opening 11 is opened at the front side of the casing 10, and the first air outlet 21 is opened at the front side of the air duct 20, so that the first air blowing opening 11 can blow air forward far away. As shown in fig. 5, the air inlet on the casing 10 may include a first air inlet 131 opened at the rear side and the left and right sides of the lower portion of the casing 10, and a second air inlet 132 opened at the upper portion of the casing 10 corresponding to the first air outlet 11, and an end of the air guide member 30 far away from the first air outlet 21 is covered and fastened with the second air inlet 132. The first air inlet 131 and the second air inlet 132 are relatively, the air entering the housing 10 from the first air inlet 131 reaches the first air outlet 21 through the air outlet gap 25, and the air entering the housing 10 from the second air inlet 132 reaches the first air outlet 21 through the diversion member 30. In addition, other air supply ports can be arranged on the shell 10 to be matched with the first air supply port 11 for use, so that various air supply modes can be realized. For example, as shown in fig. 5, the air duct 20 has two second air outlets 22. The casing 10 has two second supply ports 12 to match with the two second air outlets 22, respectively. Two second blowing ports 12 are opened at both lateral sides of the casing 10, respectively. For example, the first air blowing port 11 may be located at the upper part of the casing 10, and the two second air blowing ports 12 may be located at the middle part of the casing 10, so that the air blown by each air blowing port is staggered in the vertical direction and the left-right direction, thereby forming an air blowing effect, further dispersing the air flow, and improving the cooling/heating speed and the air flow comfort of the indoor unit of the floor air conditioner. An air guide mechanism may be installed at each second air blowing opening 12, for example, an air guide plate having an axis extending in a vertical direction may be installed at each second air blowing opening 12 so as to rotatably guide the air blowing direction.
As shown in fig. 2 to 5, in some embodiments, the inner wall of the air duct 20 adjacent to the first air outlet 21 is tapered, the flow cross section of which gradually decreases along the airflow direction, and the air outlet gap 25 is an annular air outlet gap 25 defined by the flow guide 30 and the tapered portion of the air duct 20; and the flow guide member 30 is configured to guide the airflow in the housing 10 to the annular air outlet gap 25 and make the airflow gradually converge toward the airflow center direction under the guidance of the inner wall of the air duct 20 (the airflow direction is indicated by arrows in fig. 2 to 4). In other words, the flow cross section of the air duct 20 becomes gradually smaller in the air flow direction adjacent to the first air outlet 21. The ring shape is not limited to a circular ring shape, and may be other various "ring shapes" such as a long circular ring shape, a square ring shape, an elliptical ring shape, and the like. In the indoor unit of the vertical air conditioner of the embodiment of the invention, the inner wall of the air duct 20 close to the first air outlet 21 is tapered, so that the flow cross section is gradually reduced along the airflow direction. And, the deflector 30 inside the air duct 20 and the tapered portion of the inner wall of the air duct 20 define an annular air outlet gap 25. In this way, the air flow entering the air duct 20 from the air inlet 23 of the air duct 20 flows to the first air outlet 21, and is guided by the flow guiding member 30 to blow toward the inner wall of the air duct 20, and finally flows into the annular air outlet gap 25. Because the air outlet cross section of the annular air outlet gap 25 is smaller, the air outlet speed is higher. The high-speed airflow is gradually converged towards the center of the airflow in the outward flowing process under the guidance of the gradually-reduced inner wall of the air duct 20 to form a convergence effect, so that the wind power is stronger, the air supply distance is longer, and the requirements of the indoor unit of the vertical air conditioner on long-distance air supply and strong air supply are met. In the indoor unit of the vertical air conditioner of the embodiment of the invention, the flow guide member 30 not only defines the annular air outlet gap 25 with the inner wall of the air duct 20, so as to achieve the effect of increasing the air speed, but also just guides the air flow to the annular air outlet gap 25, or forces the air flow to flow towards the annular air outlet gap 25, so as to force the air flow to be subjected to the polymerization and guidance of the tapered inner wall, and form the final polymerization air outlet effect. The invention realizes a very good polymerization air supply effect only by improving the air duct 20 and additionally arranging the flow guide piece 30, has very simple structure and lower cost, is easy to realize mass production and popularization, and has very ingenious conception. Meanwhile, the gathered wind energy further promotes the air outside the shell 10 to enter the flow guide piece 30 from the air inlet hole, so that a better flow guide effect is realized, the proportion of natural wind in the airflow of the first air supply opening 11 is increased, and the blowing feeling of a user is better.
In some embodiments, as shown in fig. 2 to 4, the air duct 20 is configured to make the upward angle of the air flow in the bottom section 252 of the annular air outlet gap 25 greater than the downward angle of the air flow in the top section 251 thereof, so that the air flow in the bottom section 252 of the annular air outlet gap 25 drives the air flow in the remaining sections to flow upward and forward together. The upward-raising angle refers to an angle between the airflow direction (as shown by the hollow arrow in fig. 2) of the bottom section 252 of the annular air outlet gap 25 and the horizontal plane, and the downward-lowering angle refers to an angle between the airflow direction of the top section 251 of the annular air outlet gap 25 and the horizontal plane (if the airflow is blown out horizontally, the downward-lowering angle is 0 °). Because the rising angle of the air flow rising part is larger than the declining angle of the sinking part, the air flow mixed by a plurality of air flows integrally rises and flows. In the refrigeration mode, the rising and flowing cold air can fully avoid the human body and scatter downwards after reaching the highest point, so that the shower type refrigeration experience is realized. Moreover, the air flow is blown upwards to be beneficial to improving the air supply distance.
For example, as shown in fig. 2, the inner walls of the air duct 20 adjacent to the top edge and the two lateral side edges of the first air outlet 21 are inclined gradually from back to front toward the horizontal central axis of the first air outlet 21, and the inner walls adjacent to the bottom edge of the first air outlet 21 extend in the vertical direction; and the air inlet 23 is positioned lower than the first air outlet 21 so that the bottom section 252 of the annular air outlet gap 25 is located upstream of the air duct 20 compared to the other sections. The air flow uplift angle at the bottom of the annular air outlet gap 25 is the largest and is 90 degrees, so that the gap space of the bottom section 252 of the annular air outlet gap 25 is larger. Based on the above two designs, the bottom section 252 of the annular air-out gap 25 has a larger air volume and stronger wind power than the rest sections. The bottom powerful airflow has advantages in the processes of impact and polymerization with the airflow on the upper part of the annular air outlet gap 25 and the airflow on the two transverse sides, and the airflow is more powerfully driven to integrally lift and flow upwards and upwards together, so that a better lifting and air supply effect is realized.
In some embodiments, as shown in FIG. 5, the duct 20 may be provided with a constriction 27 having a smaller flow cross-sectional area than the remaining sections. The neck section 27 is located on the upstream side of the baffle 30, for example, at a position adjacent to the first air outlet 21. The constriction 27 accelerates the air flow before it reaches the flow guide 30, so that the air flow impacts the flow guide 30 at a faster speed, and is thus more strongly guided by the flow guide 30 towards the inner wall of the air duct 20. In addition, a plurality of flow guiding ribs extending along the airflow direction may be disposed on the inner wall of the air duct 20 to guide the airflow, and the structural strength of the air duct 20 may also be enhanced.
With continued reference to fig. 5, in some embodiments, the wind tunnel 20 may include a front shell 201, a rear shell 202, and a drip tray 203. The rear side and the lower side of the front case 201 are opened, and the first air outlet 21 is opened on the front case 201. The front side and the lower side of the rear shell 202 are opened, and the rear shell 202 covers and buckles the rear side of the front shell 201 to form a structure with the lower side opened together. The drain pan 203 is covered and fastened to the lower sides of the front and rear cases 201 and 202 to close the open lower sides thereof. The air inlet 23 of the air duct 20 opens on the water pan 203. In the embodiment, the air duct 20 is divided into three parts, namely a front shell 201, a rear shell 202 and a water pan 203, so that the parts can be independently processed and manufactured conveniently, and the performance requirement can be better met.
The indoor stand air conditioner may have a heat exchanger 40 and a first fan 501. In some embodiments, as shown in FIG. 5, the heat exchanger 40 may be disposed inside the wind tunnel 20 and mounted on the drip tray 203. The heat exchanger 40 may be a two-stage structure, and includes a first heat exchange section 401 and a second heat exchange section 402, the first heat exchange section 401 and the second heat exchange section 402 are both flat-plate-shaped, and top ends of the two heat exchange sections are connected, and bottom ends of the two heat exchange sections are disposed on the water pan 203 and located at two sides of the air inlet 23 respectively. The inverted v-shaped structure of the heat exchanger 40 can make the heat exchange area large enough, and make the contact with the air flow flowing upwards from the air inlet 23 more sufficient, and the heat exchange efficiency is higher. The water pan 203 is used for carrying the heat exchanger 40 on one hand and receiving condensed water dropping from the surface of the heat exchanger 40 during air conditioning and refrigeration on the other hand. As mentioned above, the air duct 20 may be located at the middle upper portion of the housing 10, and one or more first air inlets 131 are opened at the lower portion of the housing 10, for example, as shown in fig. 5, the first air inlets 131 are opened at the rear side and the lateral sides of the housing 10. The heat exchanger 40 is used for exchanging heat of the airflow entering the air duct 20 through the first air inlet 131 and the air inlet 23. Here, the heat exchanger 40 is defined to exchange heat with the air entering the housing 10 through the first air inlet 131, and as mentioned above, the first air inlet 131 and the second air inlet 132 are relative terms, and the air entering the housing 10 through the first air inlet 131 may or may not be exchanged heat with the heat exchanger 40, but the air entering the housing 10 through the second air inlet 132 is not necessarily exchanged heat with the heat exchanger 40. The first fan 501 may be installed below the air duct 20 upstream of the heat exchanger 40 to face the air inlet 23 so as to blow the air flow entering the lower space of the housing 10 from the first air inlet 131 toward the inside of the air duct 20. The first fan 501 may be a double suction centrifugal fan as shown in fig. 5, or may be another type of fan. When the first fan 501 is a double-suction centrifugal fan, a motor, a volute 510, an auxiliary air duct 511 connected to the volute 510 and the air duct 20, and the like are also provided.
In some embodiments, as shown in fig. 2-5, the outer surface of the flow guide 30 includes an outer end surface 31 and a wind guide surface 33. The outer end face 31 faces the first air outlet 21, and the outer end face 31 is provided with a plurality of air outlet holes 34. The air guide surface 33 extends from an edge of the outer end surface 31 in a direction away from the first air outlet 21, and the air guide surface 33 is configured such that the edge defines an air intake hole. The air guide surface 33 is mainly used for guiding the air flow, so that the air flow can flow to the inner wall of the air duct 20 more smoothly and stably. The air inlet holes are defined by the edges of the air guide surface 33, that is, only one air inlet hole is formed in the rear surface of the whole flow guide member 30, so that the whole structure of the flow guide member 30 is simplified, and the production and the application are convenient. In some embodiments, the air guiding element 30 may include a first air guiding shell 301 and a second air guiding shell 302 that are snap-connected, an outer surface of the first air guiding shell 301 forms the outer end surface 31, and an outer surface of the second air guiding shell 302 forms the air guiding surface 33.

In addition, the indoor unit of the vertical air conditioner may further be provided with a front trim (not shown in the drawings), which has a structure matching the shape of the outer end surface 31 of the air guide member 30 and is configured to movably shield the outer end surface 31 of the air guide member 30, so that the outer end surface 31 of the air guide member 30 can be shielded when air mixing, that is, air outlet from the air outlet hole 34 is not needed, and at this time, the indoor unit of the vertical air conditioner outputs air only from the annular air outlet gap 25, so as to achieve rapid cooling or heating.
Referring now to fig. 3, in some embodiments, the indoor unit of a floor air conditioner further includes: and a second fan 502 disposed inside the baffle 30 for forcing the air outside the housing 10 to flow into the air inlet holes and then out of the air outlet holes 34. The second fan 502 may be an axial fan as shown in fig. 2 and 3, or may be another type of fan. Preferably, the vertical air-conditioning indoor unit further includes a flow guiding channel 60 disposed in the flow guiding element 30, one end of the flow guiding channel is disposed near the air outlet 34, and the other end of the flow guiding channel is adapted to the air inlet, and the air outside the casing 10 flows through the flow guiding channel 60 and then flows out of the flow guiding element 30 from the air outlet 34 to the first air outlet 21; the second fan 502 is disposed in the draft channel 60. The second fan 502 can be conveniently fixed by providing the flow guide channel 60, and on the other hand, the inlet end of the flow guide channel 60 is generally smaller than the size of the air inlet hole, so that the air outside the housing 10 can be guided by the second fan 502, and the air outside the housing 10 can be guided to the front surface of the flow guide 30 from the rear side of the housing 10 more quickly. When the inlet end of the flow directing passage 60 is generally smaller than the air inlet opening, the second air inlet opening 132 may also be sized to match the size of the inlet end of the flow directing passage 60.
Referring now to fig. 4 and 5, in some embodiments, the indoor unit of a floor air conditioner further includes: one end of the induced air pipe 70 is connected to the air inlet, the other end is located in the outdoor environment, and the outdoor air flows into the diversion member 30 through the induced air pipe 70, flows out of the diversion member 30 from the air outlet 34, and reaches the first air outlet 21. By providing the draft tube 70, air from the outdoor environment can be introduced into the baffle 30. The connecting of the induced duct 70 to the air inlet includes the direct connecting of the outlet end of the induced duct 70 to the flow guide 30, or the connecting of the outlet end of the induced duct 70 to the inlet end of the flow guide channel 60. Preferably, the induced duct 70 is connected to the inlet end of the flow guiding channel 60, while the outlet end of the induced duct 70 is smaller than the inlet end of the flow guiding channel 60, i.e. there is still a passage between the induced duct 70 and the flow guiding channel 60 for the indoor air to enter, so that the air entering the flow guiding channel 60, i.e. inside the flow guiding element 30, comprises the fresh air of the outdoor environment and the indoor air (for example, the air flow direction is shown in fig. 4) entering from the induced duct 70, and accordingly, the air reaching the first air supply opening 11 can be composed of three air flows: the air after the heat exchange of heat exchanger 40, the new trend of outdoor environment and indoor air not only can accelerate indoor air and flow like this, more can increase user experience comfort level. In addition, when the air guiding pipe 70 is provided, the indoor unit of the floor air conditioner can also independently operate in a fresh air mode, that is, the heat exchanger 40 does not work, and only the air guiding pipe 70 guides fresh air in the outdoor environment into the room. With continued reference to fig. 4 and 5, in some embodiments, the indoor unit of a floor air conditioner further includes: and the purification module 80 is arranged in the induced air pipe 70 and/or between the outlet end of the induced air pipe 70 and the air outlet 34 and is used for purifying the outdoor air. In embodiments where a diversion channel 60 and a second fan 502 are provided, as shown in FIG. 4, the purge module 80 is disposed within the diversion channel 60 downstream of the second fan 502. The specific structural components of the purification module 80 may adopt any module capable of realizing an air purification function in the prior art, and will not be described in detail herein.
In some embodiments, as shown in fig. 1 and 5, the first air supply outlet 11, the first air outlet 21 and the flow guide member 30 are all oblong with a length direction vertically arranged as a whole. An oblong refers to a shape formed by two parallel spaced straight sides joined by two symmetrically disposed arcs (usually semicircles). In the present embodiment, the first air blowing port 11 is formed in an oblong shape, and the following three points are considered. On one hand, compared with a circular air supply outlet which is used conventionally, the overall shape of the oblong air supply outlet with the same air outlet area is more 'flat', and airflow aggregation is facilitated. On the other hand, because the oblong air supply outlet is vertically arranged in the length direction, compared with a round air outlet with the same air outlet area, the height (the distance from the highest point to the lowest point of the air supply outlet) of the air supply outlet is higher, and the length of the blown air flow in the vertical direction is longer. The air flow with longer length is blown forward or blown upwards, and then the covered length (the size of the air flow landing area along the front-back direction) is longer after falling on the ground in front of the air conditioner due to gravity, and the space of the air flow coverage area is larger. For example, when the height of the air blowing opening is 20cm, the coverage length of the air flow after falling to the ground is 2m, and when the height of the air blowing opening is 25cm, the coverage length of the air flow after falling to the ground can reach 3 m. In a third aspect, compared with a traditional circular air supply outlet, the shape of the oblong air supply outlet is more matched with that of the shell 10 (the shell 10 is a long strip vertically arranged in the length direction), so that the oblong air supply outlet is more harmonious and attractive.
Thus, it should be appreciated by those skilled in the art that while a number of exemplary embodiments of the invention have been illustrated and described in detail herein, many other variations or modifications consistent with the principles of the invention may be directly determined or derived from the disclosure of the present invention without departing from the spirit and scope of the invention. Accordingly, the scope of the invention should be understood and interpreted to cover all such other variations or modifications.
