The utility model provides a vertical air conditioner indoor unit. An indoor unit of a floor type air conditioner is an indoor part of a split type air conditioner for conditioning indoor air, such as cooling/heating, dehumidifying, introducing fresh air, and the like. The vertical air conditioner indoor machine can be a conventional floor type cabinet machine or a vertical wall-mounted machine.
Fig. 1 is a schematic front view of a vertical air conditioner indoor unit according to an embodiment of the present invention, and fig. 2 is an enlarged view of an N-N sectional view of fig. 1. In FIG. 2, the flow direction of the heat exchange gas flow is indicated by solid arrows, and the flow direction of the non-heat exchange gas flow is indicated by hollow arrows.
As shown in fig. 1 and 2, the indoor unit of a floor type air conditioner according to an embodiment of the present invention may generally include a first casing 10 and a second casing 20.
The first cylindrical shell 10 is in a vertical cylindrical shape, that is, a hollow cylindrical shell. A first air outlet 12 for blowing out heat exchange air flow is opened on the front side of the first cylindrical shell 10. The "heat exchange airflow" refers to airflow that exchanges heat with the heat exchanger 17 of the air conditioner and is used for adjusting the indoor temperature. The heat exchanger 17 is connected with a compressor, a heat exchanger of an outdoor unit, a throttling device and other refrigeration elements through pipelines to form a vapor compression refrigeration cycle system. When the vertical air conditioner indoor unit is in a refrigeration mode, the heat exchange airflow is cold air; when the vertical air conditioner indoor unit is in a heating mode, the heat exchange air flow is hot air. The heat transfer gas flows through the first air outlet 12 and is blown to the indoor environment, thereby completing the refrigeration and heating of the indoor environment.
The second cylindrical shell 20 is in a vertical cylindrical shape, that is, a hollow cylindrical shell. A second air outlet 22 for blowing out non-heat exchange air flow is opened at the front side of the second cylindrical shell 20. Specifically, the non-heat exchange air flow may be one or more of indoor air, fresh air flow, purified air flow, humidified air flow or water washing air flow, and is used for auxiliary regulation of indoor environment. The second column casing 20 and the first column casing 10 are arranged in the lateral direction, and an air-inducing space 13 is formed therebetween. The front and rear of the induced draft space 13 are both communicated with the indoor environment. The "lateral direction" is indicated in the drawings, and the left-right direction perpendicular to the front-rear direction of the indoor unit of the floor air conditioner is the "lateral direction". The utility model discloses when the vertical air conditioner indoor unit moves, can make first column shell 10 and 20 alternatives of second column shell or open the air supply simultaneously. When the first air outlet 12 and/or the second air outlet 22 is/are exhausted, the indoor air in the induced draft interval 13 is driven to flow forwards under the action of negative pressure.
The first outlet 12 and the second outlet 22 may be a vertical bar extending from top to bottom, or may be an intermittent vertical bar formed by a plurality of vertically arranged sub-outlets, so as to fully utilize the height space of the first cylindrical shell 10 and the second cylindrical shell 20.
The existing vertical air conditioner indoor unit has the defects of unobvious appearance difference and poor air supply experience, so that users have many complaints. Particularly, when an air conditioner is used for refrigeration, the air outlet temperature is low, the air speed is high, and cold air is blown directly to a human body to cause discomfort, so that the wind is hard and not soft enough.
The embodiment of the utility model provides an in, when first shell 10 and/or second shell 20 air-out, locate to form negative pressure environment at induced air interval 13, make the indoor air at vertical air conditioning indoor set rear flow forward through induced air interval 13 to sneak into the air-out air current of first shell 10 or second shell 20, form the drainage and mix the wind effect. Compared with heat exchange airflow, the temperature of the mixed air flow is closer to room temperature, the comfort is higher, the wind sense is softer, the air quantity and the air speed are increased, and the air supply distance is longer.
In some embodiments of the present invention, the vertical air conditioning indoor unit is further configured to: the operation mode is provided in which the heat-exchange air flow blown out from the first outlet 12 and the non-heat-exchange air flow blown out from the second outlet 22 are mixed in front of the indoor unit of the floor standing air conditioner. Specifically, the normal directions of the first outlet 12 and the second outlet 22 may be clamped by an angle greater than 0, so that the two outlet air flows can be mixed. Of course, the air guide structure is used for guiding air, so that the two air outlet flows can be mixed. Thus, when the indoor air is blown out from the second cylindrical shell 20, the mixing amount of the indoor air is larger, the mixing speed is higher, a stronger air mixing effect can be realized, and the airflow is closer to the room temperature. When the second cylindrical shell 20 blows out conditioning air flows such as fresh air flow, purified air flow, humidifying air flow or washing air flow, the conditioning air flows can be mixed with the heat exchange air flow more early and more, the mixing rate is enhanced, and the conditioning air flows can be better diffused to all places indoors.
In addition, because need not to set up the heat exchanger in the second shell 20, can be thinner with the design of second shell 20 ground, make it obviously be thinner than first shell 10, this kind of asymmetric design both had satisfied the needs of mixing the wind just, made the outward appearance of vertical air conditioning indoor set novel more unique again, had promoted the competitiveness of product.
For example, the ratio of the width of the second column housing 20 in the lateral direction to the width of the first column housing 10 in the lateral direction may be made smaller than 1/2. The width refers to a distance between two points at which the outer wall of the second cylindrical shell 20 or the first cylindrical shell 10 is farthest in the lateral direction on both lateral sides. The ratio of the depth dimension of the second column casing 20 in the front-rear direction to the depth dimension of the first column casing 10 in the front-rear direction is less than 1/2, which means the distance between two points at which the front and rear outer walls of the second column casing 20 or the first column casing 10 are farthest in the front-rear direction. Thus, the size difference between the two is large enough to form a double-column differentiated appearance. The second outlet 22 can be flush or substantially flush with the front and back of the first outlet 12, for example, the distance between the front and back is not more than 5cm, so that the non-heat exchange air flow and the heat exchange air flow are mixed better.
In some embodiments, as shown in fig. 2, a second air duct 25 communicating with the second air outlet 22 is disposed in the second cylindrical shell 20, so that the non-heat-exchange air flow in the second cylindrical shell 20 is guided to the second air outlet 22 more smoothly. The distance between the two lateral side walls 251, 252 of the second air duct 25 is gradually reduced from back to front, forming a taper. The tapered air duct can accelerate the air flow, so that the non-heat-exchange air flow can be blown out of the second air outlet 22 more quickly, and the negative influence of the wind speed caused by no fan arranged in the second cylindrical shell 20 can be compensated to a certain extent.
In some embodiments, as shown in fig. 2, the air inducing space 13 may be a gradually expanding shape with a gradually increasing transverse dimension from back to front, so that the air outlet flows of the first air outlet 12 and the second air outlet 22 can better form a negative pressure at the outlet area of the air inducing space 13, so that the air flow of the air inducing space 13 is larger.
Fig. 3 is an enlarged view of fig. 2 at a, fig. 4 is a schematic view of the indoor stand air conditioner shown in fig. 2 when switched to the left air blowing mode, and fig. 5 is a schematic view of the indoor stand air conditioner shown in fig. 2 when switched to the right air blowing mode.
In some embodiments, as shown in fig. 2 to 5, a wind guide 26 for guiding the wind direction of the second wind outlet 22 is installed on the second cylindrical shell 20. "directing the lateral wind direction" refers to changing the angle between the wind direction and the front-back direction, for example, blowing the wind forward right, forward left, forward right, and so on. In addition, the first cylindrical shell 10 is provided with an air guide swing vane 16 for guiding the transverse air outlet direction of the first air outlet 12.
The vertical air conditioner indoor unit can change the included angle between the non-heat exchange air flow and the heat exchange air flow by adjusting the air outlet direction of the first air outlet 12 and/or the second air outlet 22, so as to change the intersection position of the non-heat exchange air flow and the heat exchange air flow. Specifically, the larger the included angle between the wind direction of the heat exchange airflow and the wind direction of the heat exchange airflow is, the closer the intersection position is, that is, the closer to the indoor unit of the vertical air conditioner is; the smaller the included angle is, the farther the intersection position is, namely, the farther away the vertical air conditioner indoor unit is. The vertical air conditioner indoor unit can adjust the intersection position according to the position of a human body so as to avoid the intersection position from approaching the human body and causing discomfort to the human body.
In addition, the indoor unit of the floor air conditioner may be further configured to: the air guide 26 is used to adjust the transverse air outlet direction of the second air outlet 22, so that the non-heat-exchange air flow can be converged into the heat-exchange air flow of the first air outlet 12. That is, after the air guiding swing blade 16 changes the air outlet direction of the heat exchange air flow, the air guiding member 26 is controlled to operate, so as to ensure that the non-heat exchange air flow can always converge into the heat exchange air flow. For example, as shown in fig. 2, when the air guide flaps 16 swing forward, the air guide 26 guides the air forward. As shown in fig. 4, when the air guide flaps 16 swing to the left, the air guide 26 is guided to the left. As shown in fig. 5, when the air guide flaps 16 swing to the right, the air guide 26 is guided to the right. The main control board of the air conditioner can be electrically connected with the air guide 26 and the motor of the air guide swing blade 16 at the same time so as to control the two to act cooperatively.
In some embodiments, as shown in fig. 3, the air guide 26 may include a first plate 261 and a second plate 262 which are laterally spaced apart. Of course, the second plate 262 is connected to the first plate 261 by other structures, which are not shown in fig. 3. The end of the first plate 261 close to the second plate 262 has a bent portion 2611 that bends backwards, and an air guiding channel 260 that is gradually narrowed from back to front is formed between the bent portion 2611 and the second plate 262. The air guide 26 is rotatably mounted to the second column casing 20 about a vertical axis x, so as to change the lateral air outlet direction of the second air outlet 22 by adjusting the relative position of the air guide channel 260 and the second air outlet 22.
For example, as shown in fig. 2 and 3, when the air guiding channel 260 faces the second air outlet 22, the non-heat-exchange air flow is guided to be blown out towards the front. As shown in fig. 4, the air guide 26 is rotated clockwise with respect to the state of fig. 2, so that the air guide passage 260 is directed to the front left, and the non-heat-exchanged air flow is guided to be blown out to the front left. As shown in fig. 5, the air guide 26 is rotated counterclockwise with respect to the state of fig. 2, so that the air guide passage 260 faces the front right direction, so as to guide the non-heat-exchanged air flow to be blown out toward the front right direction. The air guide piece of the embodiment has a very simple structure, occupies a small space, is particularly suitable for the narrow air outlet of the second air outlet 22, and is skillfully designed.
In some embodiments, as shown in fig. 3, a second air duct 25 communicating with the second air outlet 22 may be disposed in the second cylindrical housing 20. One lateral side wall 251 of the second air duct 25 defines a receiving slot 2512, and the other lateral side wall 252 defines a recess 2523. When the air guide 26 rotates to a transverse limit angle, the first plate 261 is extended into the receiving groove 2512, so that the air guide surface of the bent portion 2611 is flush with the surface of the transverse side wall 251 of the second air duct 25, as shown in fig. 4, and air flow can enter the air guide channel 260 from the second air duct 25 more smoothly. Similarly, when the air guide 26 is rotated to another lateral limit angle, the second plate 262 is inserted into the recess 2523, so that the air guide surface of the second plate 262 is flush with the surface of the lateral side wall 252 of the second air duct 25, as shown in fig. 5.
Fig. 6 is a schematic view of the indoor stand air-conditioner shown in fig. 2 when the second outlet 22 is closed.
In some embodiments, the second air outlet 22 can be closed by the air guide 26. As shown in fig. 6, the air guide 26 is rotated to a position where the first plate 261 closes the second outlet 22, so as to close the second outlet 22.
In some alternative embodiments, a conventional rotating air deflector may also be used to direct the air exiting from the second outlet 22.

In some embodiments, if the non-heat exchange gas stream is a purge gas stream, a humidification gas stream, or a water wash gas stream, a purge module, a humidification module, or a water wash module may be disposed in the lower column housing 30.
In some embodiments, as shown in fig. 8, the second outlet 22 is vertical. A second air duct 25 in a vertical bar shape is arranged in the second cylindrical shell 20 and communicated with the second air outlet 22, a plurality of guide vanes 23 arranged vertically are arranged in the second air duct 25, each guide vane 23 extends from front to back, and the rear end of each guide vane is bent downwards to form a guide bending part 231. The non-heat-exchange air flow flows from bottom to top, and after meeting each guide vane 23, the non-heat-exchange air flow is guided by the guide bending part 231 thereof, and gradually changes from top to front. Therefore, the diversion bending part 231 plays a role in changing the direction of the airflow, so that the turning of the airflow is smoother, and the wind loss is smaller. The diversion bent part 231 is in round transition with the rest of the diversion sheet 23.
Further, considering that the non-heat-exchange air flow enters the second casing 20 from the bottom of the second casing 20, the air output at the middle or upper part of the second air outlet 22 may be smaller. Therefore, the embodiment of the utility model provides a set up a plurality of water conservancy diversion pieces 23 of vertical arrangement in second column shell 20 very much to the position leans on the water conservancy diversion piece 23 before more, the rear end distance is big more, makes second air outlet 22 more even at vertical everywhere air-out.
