The invention provides a floor type air conditioner indoor unit.

In the embodiment of the present invention, as shown in fig. 1 to 5, 12 and 13, the floor type air conditioner indoor unit includes a main unit 100 and a sub-unit 200, wherein the sub-unit 200 is detachably connected to the main unit 100 and can independently operate with respect to the main unit 100; the sub-machine 200 comprises a machine shell 210, a first fan assembly 230 and an air outlet ring 231; the first fan assembly 230 is arranged on the casing 210, and the first fan assembly 230 is provided with a first air inlet 203; the air outlet ring 231 is provided with a first air outlet 204 disposed around the periphery of the air outlet ring 231.

The floor type air conditioner indoor unit is used for conditioning indoor air, an indoor heat exchange module can be arranged in the main unit 100 to be used for heat exchange conditioning of the indoor air, such as refrigeration, heating and the like, and the structure of the specific heat exchange module of the main unit 100 can refer to the existing technology of the floor type air conditioner indoor unit, and is not described herein again. The sub-machine 200 has an air outlet function to adjust the indoor air by blowing, the sub-machine 200 can be separably connected to the main machine 100, so that the sub-machine 200 can be communicated with and independent of the main machine 100 for adjusting the indoor air, the heat exchange effect of the indoor heat exchange module can not be influenced when the sub-machine 200 is connected with and separated from the main machine 100, and the heat exchange stability of the whole floor type air conditioner indoor machine is ensured.

It can be understood that the connection mode between the sub-machine 200 and the main machine 100 can be determined according to actual conditions, the sub-machine 200 can be connected inside the main machine 100 or outside the main machine 100, and optionally, the specific connection structure between the sub-machine 200 and the main machine 100 can be a snap connection, a magnetic connection or an insertion connection, etc. When the sub-machine 200 is separated from the main machine 100, the sub-machine 200 can move indoors relative to the main machine 100 to meet different indoor air conditioning requirements, for example, under the condition that the main machine 100 exchanges heat with the space of a certain indoor area, the sub-machine 200 can relay air supply to other indoor areas, so that the air of other areas can be exchanged heat quickly, and the air heat exchange conditioning range is enlarged; or when the main machine 100 is not started, the sub machine 200 independently supplies air for adjustment, so as to play a role in independently adjusting air; or when a plurality of people gather in the indoor area, the air supply can be realized in a long distance, fixed point and orientation way, and the air treatment effect is improved.

In this embodiment, the sub-machine 200 includes a first fan assembly 230 and an air outlet ring 231, which are disposed on the housing 210, the first fan assembly 230 is provided with a first air inlet 203, and the air outlet ring 231 is provided with a first air outlet 204, so that indoor air can enter the housing 210 from the first air inlet 203 and then be blown out from the first air outlet 204, thereby implementing an indoor air supply function. It can be understood that the air outlet ring 231 has a central through hole 231a, the first air outlet 204 is disposed around the periphery of the air outlet ring 231, when the first air outlet 204 blows air indoors, a negative pressure is formed at the periphery of the air outlet ring 231, so as to guide the air at the periphery of the first air outlet 204 and the central through hole 231a to the air outlet flow blown out from the first air outlet 204, and mix with the air outlet flow, so as to achieve the effect of increasing the amount of the supplied air.

In practical applications, the specific position of the air outlet ring 231 may be determined according to practical situations, for example, the air outlet ring may be disposed on the top or the side of the housing 210, so that the airflow blown out from the first air outlet 204 can be blown out toward the side, or blown out toward the upper side, or blown out toward the obliquely upper side, and the like, thereby meeting the air blowing requirements at different heights or directions, and simultaneously realizing the relay air blowing function for different indoor areas. If the main unit 100 is fixedly arranged in the living room, when the heat exchange effect of the main unit 100 to the air in the living room cannot cover other areas such as a kitchen or a bedroom, the sub-unit 200 can be placed at the doorway of the kitchen or the bedroom, and the first air outlet 204 of the air outlet ring 231 faces the kitchen or the bedroom, so that the air after heat exchange in the living room can be drained to be mixed with the air outlet flow blown out by the first air outlet 204 through the central through hole 231a of the air outlet ring 231 and the periphery of the air outlet ring 231 through the drainage function of the air outlet ring 231, the mixed air is blown to the kitchen or the bedroom, the air volume blown to the kitchen or the bedroom is increased, and the air conditioning efficiency in the kitchen or the bedroom is improved. Or, the sub-machine 200 may be placed inside a kitchen or a bedroom, and negative pressure is formed at the first air outlet 204 through the air outlet ring 231, so that heat exchange air in the living room is sucked into the kitchen or the bedroom, and air in the kitchen or the bedroom is adjusted. It should be noted that, considering that the air outlet of the main unit 100 of the floor type air conditioning indoor unit is usually located at a higher position, and the air flow blown out by the main unit 100 is blown out from the higher position, optionally, the air outlet ring 231 may be disposed at the top or upper position of the casing 210 of the sub-unit 200, so as to achieve a better relay air supply effect and achieve air conditioning of more indoor areas.

Optionally, the wind-out ring 231 may be fixedly disposed on the casing 210, or may be movably connected to the casing 210. When the wind outlet 231 is fixed to the casing 210, in order to increase the wind outlet amount, the wind outlet 231 may be disposed outside the casing 210, so that the central through hole 231a of the wind outlet 231 can smoothly guide the wind. When the air outlet ring 231 is movably connected with the casing 210, the air outlet ring 231 moves to the outside of the casing 210 when the first air outlet 204 needs to be exhausted, so that the multi-function of drainage and air supply is realized; when the first air outlet 204 does not vent air, the air outlet ring 231 moves to be accommodated in the casing 210, so as to achieve the integrity of the appearance of the whole machine and protect the air outlet ring 231.

It can be understood that the air outlet ring 231 may be circular arc, rectangular, triangular, or other special shapes, as long as the air outlet ring 231 is ensured to have a middle through hole for the air flow to pass through. The first air outlet 204 is disposed around the periphery of the air outlet ring 231, and may be in a closed-loop air outlet form, an arc air outlet form, or a plurality of small holes distributed around the periphery of the air outlet ring 231, so that the air flow can be guided to the air outlet flow from the central through hole 231a to increase the air supply volume.

In the technical scheme of the invention, the floor type air conditioner indoor unit is provided with the sub-machine 200 which is detachably connected with the main machine 100, and the sub-machine 200 has an air outlet function so as to realize the effect of air conditioning the whole indoor area or the local area; the sub-machine 200 includes a housing 210, a first fan assembly 230 and an air outlet ring 231, the first fan assembly 230 is provided with a first air inlet 203, the air outlet ring 231 is communicated with the first fan assembly 230, the air outlet ring 231 is provided with a first air outlet 204 arranged around the periphery of the air outlet ring 231, so as to guide air at the periphery of the first air outlet 204 and at the central through hole 231a of the air outlet ring 231 to the air outlet flow blown out from the first air outlet 204, thereby achieving the effect of increasing the air supply volume.

In order to further increase the air supply range of the floor type air conditioner indoor unit, please refer to fig. 2, fig. 3, fig. 5 and fig. 9, the air outlet ring 231 is rotatably connected with the casing 210.

It can be understood that, when the air outlet ring 231 rotates relative to the casing 210, the first air outlet 204 can be driven to rotate relative to the casing 210, and then the air outlet direction of the first air outlet 204 is adjusted, so as to achieve the function of increasing the air supply range. In the practical application process, the rotation mode of the air outlet ring 231 and the casing 210 may be determined according to the practical situation, for example, the rotation mode may be implemented by a driving transmission mode such as a driving motor-driven gear combination, a sprocket combination, or a turbine-worm combination. The specific rotation direction of the wind-out ring 231 and the housing 210 is not limited, and may be left-right rotation or up-down rotation.

Optionally, the wind outlet 231 is disposed at the top of the casing 210. In practical applications, the position of the wind outlet 231 may be determined according to practical situations, such as being disposed on the top or the side of the casing 210. In this embodiment, the air outlet ring 231 is disposed at the top of the casing 210 in consideration of the air supply and flow guiding effect of the air outlet ring 231, so that the air flow blown by the main unit 100 can be better relayed to supply air while the sub unit 200 supplies air. In addition to the above embodiments, the outlet coil 231 can rotate relative to the casing 210, so that the outlet airflow of the sub-unit 200 and the outlet airflow of the main unit 100 can be guided to a wider area range, thereby achieving air conditioning of more indoor areas.

Further, the wind outlet 231 may rotate up and down with respect to the housing 210. On the basis of the foregoing embodiment, the air outlet ring 231 is disposed at the top of the casing 210, and it can be understood that when the air outlet ring 231 rotates up and down relative to the casing 210, the first air outlet 204 is driven to rotate up and down, so that the air outlet flow can be blown out in the range with different heights, and the height range of the air outlet flow is increased. When the sub-machine 200 and the main machine 100 jointly operate for relay air supply, considering that the air outlets of most of the main machines 100 are arranged at a higher position, the air outlet ring 231 can better guide the heat exchange air flow blown out from the main machine 100 to the area ranges with different heights when rotating up and down, so as to achieve different air conditioning effects.

Specifically, referring to fig. 2, fig. 3, fig. 5 and fig. 9, the first fan assembly 230 includes a first air duct shell 232 disposed at the top of the casing 210 and a first air wheel 233 disposed in the first air duct shell 232, the air outlet ring 231 is rotatably connected to the first air duct shell 232, and the first air outlet 204 is communicated with the first air duct shell 232.

As can be appreciated, the first wind wheel 233 functions to drive the airflow to drive the indoor air into the first duct shell 232 and out of the first outlet port 204 of the outlet coil 231. The first wind wheel 233 may be a centrifugal fan. The first air duct shell 232 may be accommodated in the casing 210 or may be exposed from the casing 210, and the specific arrangement position of the first air duct shell 232 may be determined according to actual conditions. It should be noted that the first air duct casing 232 may be a casing structure independent from the casing 210, or may be a part of the casing 210, so as to accommodate the first wind wheel 233 to form a guiding function for the airflow.

In an actual application process, a specific structural shape of the first air duct shell 232 may be determined according to an actual situation, optionally, the first air duct shell 232 includes a volute 2321 and a three-way pipe 2322, one end of the three-way pipe 2322 is communicated with the volute 2321, and the other two ends are both communicated with the air outlet ring 231; the air outlet ring 231 is rotatably connected with the three-way pipe 2322; the first wind wheel 233 is arranged in the volute 2321; the volute 2321 is provided with a first air inlet 203.

It can be understood that the three-way pipe 2322 plays a role of communicating the volute 2321 with the air outlet ring 231, on the basis of the foregoing embodiment, the volute 2321 is disposed at the top of the casing 210, and the air outlet ring 231 can rotate up and down, and by disposing the three-way pipe 2322, the fixed volute 2321 can be communicated with the movable air outlet ring 231, so as to achieve a function of guiding air smoothly. In this embodiment, one end of the three-way pipe 2322 is communicated with the volute 2321, and the other two ends are communicated with the air outlet ring 231, so that the airflow in the volute 2321 can enter the air outlet ring 231 from the two ends of the three-way pipe 2322 at the same time, and the flow path of the airflow in the air outlet ring 231 is reduced, thereby reducing the air volume loss, and meanwhile, the airflow in the air outlet ring 231 is more uniform by entering from the two air outlets of the air outlet ring 231, and the noise caused by unbalanced airflow is reduced.

Optionally, a rotating mechanism may be disposed at two ends of the wind outlet ring 231 connected to the three-way pipe 2322, so that the rotation of the wind outlet ring 231 is more stable and reliable through the two rotating mechanisms.

In this embodiment, the first wind wheel 233 is disposed in the volute 2321, and drives the indoor air to enter the volute 2321 from the first air inlet 203, and then passes through the three-way pipe 2322 and the air outlet ring 231 in sequence, and then is blown out from the first air outlet 204. Optionally, the first air inlet 203 is disposed at the top of the volute 2321.

Further, referring to fig. 2, 3 and 11, the housing 210 is provided with a receiving groove 211 for receiving the air outlet ring 231, and the receiving groove 231 is disposed around the periphery of the first air inlet 203.

It can be understood that the receiving groove 211 functions to receive the wind outlet ring 231, and when the wind does not need to be discharged from the first wind outlet 204, the wind outlet ring 231 can be received in the receiving groove 211, and optionally, the position of the receiving groove 211 can be determined according to actual situations, for example, the receiving groove can be disposed on the top or the side of the housing 210.

On the basis of the foregoing embodiment, the volute 2321 is disposed at the top of the housing 210, and in order to ensure the integrity of the whole appearance of the sub-machine 200, the volute 2321 is accommodated inside the housing 210, in this embodiment, the accommodating groove 211 is disposed at the periphery of the volute 2321 to surround the first air inlet 203, so that when the air outlet ring 231 is accommodated in the accommodating groove 211, the internal space at the top of the housing 210 is fully utilized around the periphery of the volute 2321. When the first fan assembly 230 operates, the air outlet ring 231 rotates to the upper side of the casing 210, so as to ensure that the central through hole 231a can pass through the air flow, and the function of increasing the air volume by drainage is realized; or when the first fan assembly 230 does not operate, the air outlet ring 231 can rotate to be accommodated in the accommodating groove 211, so that the effect of protecting the air outlet ring 231 is achieved, and meanwhile, the overall height of the sub-machine 200 is reduced.

In order to achieve better drainage effect, referring to fig. 3, 8 to 11, in an embodiment of the present invention, the first air outlet 204 is shaped like a slit. It can be understood that, the strip-shaped first air outlet 204 is compared with air outlets of other shapes, and under the condition that the air flow rate is constant, the air flow rate blown out from the strip-shaped first air outlet 204 is larger, so that the surrounding air can be better driven to enter the air outlet flow, and the effects of increasing the air blowing rate and the air supply distance are achieved. Optionally, the first air outlet 204 is disposed around the periphery of the central through hole 231a to achieve a larger air outlet area, so as to achieve a wider air supply range.

Optionally, a caliber gap of the first air outlet 204 is not less than 1mm, and not more than 4 mm. The aperture clearance of the first air outlet 204 cannot be too large or too small, and if the aperture clearance is too small, the wind resistance is easy to increase, and the air volume is reduced; if too large, the drainage effect is poor. In this embodiment, the aperture gap of the first air outlet 204 may be 1mm, 2mm, 3mm or 4 mm.

Specifically, the air outlet ring 231 has an air guide wall 2311 away from the central axis, and the air guide wall 2311 is disposed obliquely outward with respect to the central axis of the air outlet ring 231 in the direction along the air outlet flow. It can be understood that the air guide wall 2311 plays a role in guiding the outlet airflow outwards from the outlet coil 231, and in the direction along the outlet airflow, the air guide wall 2311 is arranged outwards in an inclined manner relative to the central axis, so that the outlet airflow can be outwards diffused and blown out along the air guide wall 2311, and the outlet airflow range is expanded. Meanwhile, considering the aforementioned embodiment, the first air inlet 203 is disposed at the top of the volute 2321, and the air outlet ring 231 is disposed around the periphery of the volute 2321, the air guide wall 2311 diffuses the outlet air flow outwards to prevent the outlet air flow from flowing back to the first air inlet 203.

Optionally, an inclination angle of the wind guide wall 2311 with respect to a central axis of the wind outlet ring 231 is defined to be between 0 ° and 45 °. It can be understood that the inclination angle of the air guide wall 2311 with respect to the central axis of the air outlet ring 231 cannot be too large, and if it is too large, the air guide wall 2311 has a poor air guide effect. Further, for better air guiding effect, the angle of inclination of the air guiding wall 2311 with respect to the central axis of the air outlet ring 231 is between 0 ° and 20 °, and may be, for example, 1 °, 5 °, 10 °, 15 °, or 20 °.

In an embodiment of the present invention, referring to fig. 8 to 17, the wind guiding wall 2311 includes a first wind guiding section 2311a and a second wind guiding section 2311b, and the second wind guiding section 2311b is disposed on a side of the first wind guiding section 2311a close to the first air outlet 204; the first wind guiding section 2311a is parallel to the central axis of the wind outlet ring 231, and the second wind guiding section 2311b is arranged obliquely outward relative to the first wind guiding section 2311 a.

In the present embodiment, in order to prevent short-circuiting of the air flow, the air guiding wall 2311 is provided with the first air guiding section 2311a and the second air guiding section 2311b, and the second air guiding section 2311b is inclined outward relative to the first air guiding section 2311a, so that the air flow can firstly flow along the first air guiding section 2311a to the second air guiding section 2311b and then is blown out by the second air guiding section 2311b in an outward diverging manner.

It is understood that the first air inlet 203 is disposed at the top of the volute 2321, the air outlet ring 231 is disposed around the periphery of the volute 2321, the first outlet port 204 is also disposed around the periphery of the first inlet port 203, so that the first outlet port 204 is closer to the first inlet port 203, the outlet airflow blown out from the first outlet port 204 is easily sucked into the first inlet port 203 or has a flowing tendency toward the first inlet port 203, but affects the drainage effect of the hollow area of the air outlet ring 231 and even causes the phenomenon of short circuit of the air flow, in order to prevent this, the second wind guiding section 2311b near the first wind outlet 204 is disposed to be inclined outward, so that the outlet air flow can flow along the second wind guiding section 2311b inclined outwards and is blown out from the first air outlet 204 in the direction departing from the first air inlet 203, thereby reach and reduce the influence to the drainage effect and also reach and prevent that the air-out air current from flowing back to first air intake 204 simultaneously. Specifically, referring to a comparison between fig. 14 and fig. 15 and a comparison between fig. 16 and fig. 17, it can be seen that when the second wind guiding section 2311b is inclined outward, the amount of airflow flowing back from the first wind outlet 204 to the first wind inlet 204 is reduced, and a better wind outlet guiding effect is achieved.

It should be noted that the outward inclination angle α of the second wind guiding section 2311b cannot be too large, and since the airflow flows from the first wind guiding section 2311a to the second wind guiding section 2311b, the airflow still has a flowing tendency along the first wind guiding section 2311a when flowing to the junction of the two wind guiding sections, and when the outward inclination angle α of the second wind guiding section 2311b is too large, it is easy to cause that more airflow cannot flow along the second wind guiding section 2311b, but directly disengages from the second wind guiding section 2311b, and the outward divergent blowing effect cannot be achieved. Optionally, the second wind guiding segment 2311b is inclined outward relative to the first wind guiding segment 2311a by an angle α between 0 ° and 45 °. In practical applications, the outward inclination angle α of the second wind guiding section 2311b may be 1 °, 5 °, 10 °, 15 °, or 20 °.

Further, referring to fig. 8 to 17, in order to ensure the wind guiding effect of the wind guiding wall 2311 and prevent the airflow from flowing back to the first wind inlet 203, the depth of the first wind guiding segment 2311a is defined as L1, and the depth of the second wind guiding segment 2311b is defined as L2, which satisfies the following requirements: L2/(L1+ L2) ≥ 30%, that is, the second air guiding section 2311b cannot be too short, and if the second air guiding section 2311b is too short, the effect of guiding the air flow outwards by diverging cannot be achieved.

It can be understood that, on the basis of the foregoing embodiment, since the first air outlet 204 is closer to the first air inlet 203, the outlet airflow blown out from the first air outlet 204 is easily sucked into the first air inlet 203 or has a flowing tendency toward the first air inlet 203, which affects the drainage effect of the hollow area of the air outlet ring 231 and even causes the phenomenon of short-circuit of the airflow, and in order to prevent the phenomenon, the second air guiding section 2311b near the first air outlet 204 is disposed obliquely outward. In this embodiment, in order to achieve a better effect of preventing the short circuit of the air flow, the depth L2 of the second air guiding section 2311b has a certain requirement, in the practical application process, the air flow flows from the end of the second air guiding section 2311b connected with the first air guiding section 2311a to the air outlet end of the second air guiding section 2311b to blow out from the first air outlet 204, when the depth L2 of the second air guiding section 2311b is too short, the distance between the air outlet end of the second air guiding section 2311b and the first air inlet 203 is relatively short, so that the distance between the air outlet end of the second air guiding section 2311b and the first air inlet 203 is relatively short, the trend that the air flow flowing out from the air outlet end of the second air guiding section 2311b is adsorbed by the first air inlet 203 or directly sucked in is easily caused, and therefore the depth L2 of the second air guiding section 2311b cannot be too short, which can satisfy L2/(L1+ L2) being more than or equal to 30%, so as to increase the distance between the air outlet end of the second air guiding section 2311b and the first air inlet 203, thereby reach the better effect of outwards dispersing the air-out air current, and then reach the better effect of preventing the short circuit of air current.
