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, which is cut open by a first column casing and a second column casing, and is shown with reference to fig. 2 to 13, in an embodiment of the present invention, there is provided a vertical air conditioner indoor unit, which includes a first column casing 10 and a second column casing 20. First column shell 10 is vertical column, and the front side of first column shell 10 is opened and is equipped with first air outlet 11 that is used for blowing out first air current, and first air outlet 11 is the vertical bar form. The second cylindrical shell 20 is in a vertical column shape, a second air outlet 21 for blowing out a second air flow is formed in the front side of the second cylindrical shell 20, and the second air outlet 21 is in a vertical bar shape. The second cylindrical shell 20 and the first cylindrical shell 10 are arranged in the transverse direction, and an induced draft interval 16 is formed between the two shells, so that when the first air outlet 11 and/or the second air outlet 21 are/is exhausted, air in the induced draft interval 16 is driven to flow forward under the action of negative pressure. The left-right direction perpendicular to the front-rear direction of the indoor unit of the vertical air conditioner is the "transverse direction". The second column housing 20 is laterally movably disposed to adjust the width of the induced draft space 16.

The utility model discloses when the vertical air conditioner indoor set moves, can make first column shell 10 and the alternative of second column shell 20 or open the air supply simultaneously. When the first air outlet 11 and/or the second air outlet 21 are/is exhausted, the indoor air in the induced draft interval 16 is driven to flow forwards under the action of negative pressure, and a flow guiding and air mixing effect is formed. 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. When it is necessary to change the effect of mixing air, the amount of induced air, and the like, the second column housing 20 is caused to move in the lateral direction. The induced air volume of induced air interval 16 can be changed like this, also can change first air current and the mixed wind effect of second air current simultaneously to and change the mixed wind effect of first air current, second air current and induced air current, obtain different air-out effects, more air-out forms satisfy user's individual needs, promote user and use experience.

In some embodiments of the present invention, the first outlet 11 and the second outlet 21 may be an integral vertical bar extending from top to bottom, or an intermittent vertical bar formed by a plurality of vertically arranged sub-outlets. One of the first and second gas streams is a heat exchange gas stream and the other is a non-heat exchange gas stream. The non-heat exchange air flow is one or more of indoor air, fresh air flow, purified air flow, humidifying air flow or washing air flow.

Preferably, the first air flow is preferably a heat exchange air flow, and the "heat exchange air flow" refers to an air flow which performs heat exchange with the heat exchanger 14 of the air conditioner and is used for regulating the indoor temperature. The heat exchanger 14 is connected with the compressor, the heat exchanger of the outdoor unit, the 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 air flow 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 exchange gas flows through the first air outlet 11 and is blown to the indoor environment, and the indoor environment is cooled and heated. The second air flow can be heat exchange air flow, and the non-heat exchange air flow can be one or more of indoor air, fresh air flow, purified air flow, humidifying air flow or washing air flow, and the function of the second air flow is to assist in adjusting the indoor environment.

In this embodiment, when the second cylinder case 20 also blows out the indoor air, a stronger wind mixing effect can be achieved, so that the airflow comes closer to the room temperature. When the second cylinder 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 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 the heat exchanger does not need to be arranged in the second cylindrical shell 20, the second cylindrical shell 20 can be designed to be thinner, so that the second cylindrical shell is obviously thinner than the first cylindrical shell 10, the asymmetric design not only meets the requirement of mixed air, but also enables the appearance of the vertical air conditioner indoor unit to be more novel and unique, and the competitiveness of products is improved.

For example, the ratio of the width of the second column casing 20 in the lateral direction to the width of the first column casing 10 in the lateral direction may be made smaller than 1/2. The ratio of the depth dimension of the second column shell 20 in the front-rear direction to the depth dimension of the first column shell 10 in the front-rear direction is less than 1/2 to form a dual-column differentiated appearance. The second outlet 21 may be flush or substantially flush with the front and rear positions of the first outlet 11, for example, with a front and rear distance of not more than 5cm, so as to achieve better mixing of the non-heat exchange air flow and the heat exchange air flow.

In some embodiments of the present invention, an air duct 17 is provided between the upper end of the first column casing 10 and the upper end of the second column casing 20 to communicate the front portion of the first air duct 19 with the second air duct 28.

The damper 18 is disposed at a connection position of the air duct 17 and the first air duct 19, and when the air duct 17 is closed by the damper 18, a surface of the damper 18 facing the first air duct 19 and a side wall of the first air duct 19 are located on the same plane. The damper 18 rotates about a vertically disposed axis of rotation. The damper 18 is simple in construction and is itself a movable part of the wall of the first duct 19, the damper 18 being rotatable about a vertically disposed axis of rotation. As shown in fig. 7, when the damper 18 is opened, a part of the first airflow enters the air guiding duct 17 through the damper 18. As shown in fig. 8, when the damper 18 is closed, the first air duct 19 is completely closed, and the first air flow completely flows out of the first air outlet 11.

In some embodiments of the present invention, the vertical air conditioner indoor unit further includes a driving device and a transmission device. The driving device is arranged on the second cylinder shell. The driving device drives the second cylinder shell to move transversely through the transmission device. The transmission 24 comprises a gear and a rack which are engaged with each other and fixedly connected with the first column housing 10. The gear is arranged on the driving device and driven by the driving device to rotate.

In some embodiments of the present invention, the rear wall of the first cylindrical shell 10 and the rear portions of the two side walls are provided with the first air inlet 13 communicated with the first air outlet 11. A heat exchanger 14 and a heat exchange fan 15 are arranged in the first cylindrical shell 10, the heat exchange fan 15 enables heat exchange airflow passing through the heat exchanger 14 to flow out of the first air outlet 11, and the first airflow is the heat exchange airflow at the moment.

In some embodiments of the present invention, the vertical air conditioner indoor unit further includes an induced draft fan 31. The induced draft fan 31 is used to promote the air flow into the second cylindrical housing 20 and out of the second outlet 21. The air inlet of the induced draft fan 31 can be communicated with the indoor space, so that the indoor air enters the second cylindrical shell 20 and flows out from the second air outlet 21, and at the moment, the second air flow is the indoor air. The air inlet of the induced draft fan 31 can also be communicated with the outdoor space, so that the fresh air flow enters the second cylinder shell 20 and flows out from the second air outlet 21, and at the moment, the second air flow is the fresh air flow.

In some embodiments of the present invention, the lower end of the second cylindrical shell 20 is provided with an air inlet of the second cylindrical shell 20 communicated with the second air outlet 21. The vertical air-conditioning indoor unit further comprises a lower shell 30 and a telescopic hose 34, the first cylindrical shell 10 and the second cylindrical shell 20 are arranged at the top end of the lower shell 30, and the induced draft fan 31 is an axial flow fan or a centrifugal fan and is arranged in the lower shell 30. First shell 10 and second shell 20 set up in the top of inferior valve 30, and inferior valve 30 has the effect of supporting, has also provided induced air fan 31's installation space simultaneously, can avoid setting up the fan in second shell 20 to can be thinner with second shell 20 design, it is more unique to make things convenient for nature. As shown in fig. 9, the lower casing 30 is provided with a fresh air inlet 33 and at least one indoor air inlet, which are alternatively communicated with the air inlet of the induced draft fan or simultaneously communicated with the air inlet of the induced draft fan. The fresh air inlet 33 is connected with a fresh air pipe so as to introduce fresh air flow from the outside. Further, if the second air flow is a purified air flow, a humidified air flow or a water washing air flow, a functional module 32 may be disposed in front of the air inlet of the induced air fan 31 in the lower casing, and the functional module is a corresponding purified module, a humidified module or a water washing module. The flexible hose 34 is connected with the air outlet of the induced draft fan and the air inlet of the second cylinder shell 20.

In some embodiments of the present invention, as shown in fig. 5, a second air duct 28 communicating with the second air outlet 21 is disposed in the second cylindrical shell 20 for guiding the non-heat-exchange airflow in the second cylindrical shell 20 to the second air outlet 21 more smoothly. The distance between the two side walls of the second air duct 28 is gradually reduced from back to front, forming a tapered shape. The tapered air duct can accelerate the air flow.

In some embodiments of the present invention, a third air inlet 23 communicated with the second air outlet 21 is disposed on the rear portion of the side wall of the second column shell 20 far away from the first column shell 10 and the rear wall of the second column shell 20. The above arrangement makes the air intake of the first and second cylindrical shells 10 and 20 be indoor air. The first air intake opening 13 is located at the rear side of the third air intake opening 23. Preferably, the induced draft fan 31 is a cross flow fan, which is disposed inside the second cylindrical housing 20.

In some embodiments of the present invention, as shown in fig. 9, a second air duct 28 in a vertical strip shape is disposed in the second cylindrical shell 20 and is communicated with the second air outlet 21, and the lower end of the second air duct 28 is an air inlet thereof. A plurality of flow deflectors 25 arranged vertically are arranged in the second air duct 28, each flow deflector 25 extends from front to back, and the distance between the front end and the rear end of the flow deflector 25, which is closer to the flow deflector bending part 251, is increased by bending the rear end downwards. The second airflow flows from bottom to top, and after encountering each guide vane 25, is guided by its guide bending 251 to gradually change from upward to forward flow. The diversion bent part 251 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 flow guiding bent part 251 is in rounded transition with the rest of the flow guiding sheet 25.

Further, considering that the second airflow enters the second cylindrical shell 20 from the bottom of the second cylindrical shell 20, the air outlet amount at the middle or upper part of the second air outlet 21 may be slightly smaller. Therefore, the embodiment of the utility model provides a set up a plurality of water conservancy diversion pieces 25 of vertical arrangement in second column shell 20 very much to the position leans on the water conservancy diversion piece 25 before more, the rear end distance is big more, makes second air outlet 21 more even at vertical everywhere air-out. Of course, the problem of small air output quantity in the middle or upper part of the second air outlet 21 can be fully utilized, so that the air mixing effect on the upper side is poor, and air can be supplied to places needing cold quantity, namely places needing no soft air.

In some embodiments of the present invention, the second column casing 20 is provided with a wind guide 27 for guiding the transverse wind outlet direction of the second wind outlet 21. "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, etc. In addition, a first air deflector 12 for guiding the transverse air outlet direction of the first air outlet 11 is installed on the first cylindrical shell 10.

As shown in fig. 10 to 13, the indoor unit of a floor air conditioner may be configured to: the air guide 27 is used to adjust the transverse air outlet direction of the second air outlet 21, so that the second air flow can converge into the first air flow at the first air outlet 11. That is, after the first air guiding plate changes the air outlet direction of the first air flow, the air guiding member 27 is controlled to operate, so as to ensure that the second air flow can always converge into the heat exchange air flow. For example, as shown in fig. 10, when the first air guide plate 12 swings forward, the air guide 27 guides the air forward. As shown in fig. 12, when the first air guide plate 12 swings left, the air guide 27 guides the air to the left. As shown in fig. 13, when the first air guide plate 12 swings right, the air guide 27 guides the air to the right. The main control board of the air conditioner can be electrically connected with the air guide 27 and the motor of the first air guide plate 12 at the same time, so as to control the two to act cooperatively.

The end of the first plate 271 close to the second plate 272 has a bent portion 2711 bent backward, and an air guiding channel 270 with a gradually decreasing distance from back to front is formed between the bent portion 2711 and the second plate 272. The width of the front end of the air guide channel is smaller than that of the second air outlet, and the front end of the air guide channel is in contact with the inner wall of the air channel. The air guide 27 is rotatably mounted to the second column casing 20 about a vertical axis so as to change a lateral air outlet direction of the second air outlet 21 by adjusting a relative position of the air guide passage 270 and the second air outlet 21.

For example, as shown in fig. 10 and 11, when the air guide passage 270 faces the second air outlet 21, the non-heat-exchange air flow is guided to be blown out toward the front. As shown in fig. 12, the air guide 27 is rotated clockwise with respect to the state of fig. 10, so that the air guide passage 270 is directed to the front left, and the second air flow is guided to be blown out to the front left. As shown in fig. 13, the air guide 27 is rotated counterclockwise with respect to the state of fig. 10 so that the air guide passage 270 is directed to the front right, and the second air flow is directed to the front right. The air guide 27 of the present embodiment has a very simple structure and occupies a small space, and is particularly suitable for the narrow air outlet of the second air outlet 21, and the design is very ingenious.

In some embodiments of the present invention, a side wall 281 of the second air duct 28 has a first abdicating groove 2812 and a first sliding groove 2811 communicated with the first abdicating groove 2812, another side wall 282 of the second air duct 28 has a second abdicating groove 2821, and the first plate 271 is slidably mounted on the first sliding groove 2811. The air guide 27 is rotatable to a first position and a second position.

As shown in fig. 12.

When the air guide 27 is located at the second position, the second plate 272 is embedded into the second avoiding groove 2821, and the air guide surface of the second plate 272 is located on a plane formed by the rear edge of the opening of the second avoiding groove 2821 and the vertical edge of the second air outlet 21, which is close to the second avoiding groove 2821. As shown in fig. 13.

In some embodiments of the present invention, the second air outlet 21 can be closed by the air guide 27.
