Description

Indoor unit of vertical air conditioner

Technical Field

The utility model relates to the technical field of air conditioning, in particular to a vertical air conditioner indoor unit.

Background

With the development of the age and the progress of technology, users not only expect air conditioners to have faster cooling and heating speeds, but also pay more attention to the comfort performance of the air conditioners. After the air conditioner is started to operate, a user feels cool or warm and simultaneously pays more attention to whether the wind feeling experience is comfortable.

Some existing air conditioners use a drainage air mixing technology to adjust the supply air temperature. Specifically, the indoor normal temperature air is mixed with the heat exchange air flow during the air conditioning operation. In the refrigeration mode, the temperature of the mixed air flow is higher than that of the heat exchange air flow, so that a cool and uncooled refrigeration effect is formed; in the heating mode, the temperature of the mixed air flow is lower than that of the heat exchange air flow, so that a heating effect of heat without dryness is formed, and the human body feel more comfortable.

However, in order to mix indoor air into heat exchange airflow, the existing drainage air mixing structure is widely changed for the air conditioning structure, so that the original overall shape of the air conditioner is thoroughly changed, the concealment is poor, and mass production popularization is not facilitated.

Disclosure of Invention

The utility model aims to overcome the problems or at least partially solve the problems, and provides the vertical air conditioner indoor unit with a simpler drainage and air mixing structure, so that the fusion degree of the mixed flow air guiding structure and the existing structure of the vertical air conditioner indoor unit is improved, and the influence of the drainage and air mixing structure on the structure of the vertical air conditioner indoor unit is reduced.

In particular, the present utility model provides a vertical air conditioner indoor unit comprising:

the shell is provided with a ventilation opening, and the ventilation opening penetrates through the front wall and at least one transverse side wall of the shell; and

at least one wind deflector, each wind deflector stands at a lateral side wall penetrated by the ventilation opening and has a wind guiding position for guiding indoor air at lateral side of the housing to the interior of the housing so that the indoor air is mixed into the heat exchange air flow in the interior of the housing.

Optionally, each said wind deflector is configured to taper away from a lateral side wall of said housing from a front end to a rear end when in said induced draft position.

Optionally, each said wind deflector is movably mounted to said housing for movement to a closed position parallel to a lateral side wall of said housing to conceal said vent.

Optionally, each said wind deflector is rotatably mounted to said housing about a vertical axis.

Optionally, in the closed position, the axis of rotation of the wind deflector is less from the front end of the wind deflector than from the rear end of the wind deflector.

Optionally, the vertical air conditioner indoor unit further includes: and the air guide device is arranged at the front opening part of the ventilation opening and is used for guiding the air outlet direction of the ventilation opening.

Optionally, the air guiding device includes a plurality of swing blades arranged transversely along the casing, each swing blade is in a vertical bar shape and configured to be capable of rotating around a vertical axis of the swing blade in a fixed shaft manner, and the air guiding device is configured to enable the plurality of swing blades to rotate synchronously so as to guide the air outlet direction of the ventilation opening together.

Optionally, each wind deflector is in a vertical bar shape.

Optionally, the air guiding device is configured to allow the plurality of swing blades to rotate to a coplanar state to close a portion of the vent opening forward.

Optionally, the vent extends through both of the lateral side walls of the housing; and is also provided with

The number of the wind shields is two correspondingly.

The inventive floor air conditioner indoor unit does not merely open the ventilation opening forward, but penetrates at least the front wall and at least one lateral side wall of the housing. Each wind deflector is erected at a lateral side wall penetrated by the ventilation opening and has a wind inducing position. When the vertical air conditioner indoor unit operates, heat exchange air flows are blown to the ventilation opening from back to front, and the pressure on the two lateral sides of the air flow is reduced, so that a negative pressure area is formed. And, the higher the flow rate, the lower the pressure. Under the action of negative pressure, indoor air at the lateral side of the shell enters the shell from the side part of the ventilation opening and is mixed with heat exchange airflow. In the process, the wind shield plays a role in guiding indoor air, so that drainage and wind mixing are realized.

In this way, in the refrigeration mode, the temperature of the mixed air flow is higher than that of the heat exchange air flow, so that a cool and uncooled refrigeration effect is formed; in the heating mode, the temperature of the mixed air flow is lower than that of the heat exchange air flow, so that a heating effect of heat without dryness is formed, the human body feels more comfortable, the circulation of indoor air is promoted, and the refrigerating/heating speed is higher.

Furthermore, in the vertical air conditioner indoor unit, when drainage and air mixing are not needed, the wind shield can be adjusted to the closing position, so that the wind shield shields the ventilation opening at the lateral side of the ventilation opening, and the drainage and air mixing function is closed. The utility model realizes the opening and closing of the drainage and air mixing functions by enlarging the ventilation opening and adjusting the wind shield, has ingenious conception and very simple structure. The drainage air mixing structure has small influence on the appearance of the indoor unit of the vertical air conditioner, has small influence on the internal structures such as an original air duct and a fan, and does not need to excessively adjust the layout of original components in the shell.

In the vertical air conditioner indoor unit, the wind shield is in a vertical strip shape, and the plurality of swing blades of the air guide device are in a vertical strip shape. Therefore, the wind shield and the swing blades tend to be consistent in appearance, so that the appearance integrity of the vertical air conditioner indoor unit is better, more concise and attractive.

Wherein fig. 3 and 5 illustrate the flow direction of the air flow with arrows.

As shown in fig. 1 to 5, the floor air conditioner indoor unit according to the embodiment of the present utility model may generally include a housing 10 and at least one wind deflector 60.

The housing 10 may have a vertically-erected column shape defining an accommodating space for accommodating main body components of the indoor unit of the floor air conditioner, such as the indoor side heat exchanger 20, the blower 30, the controller, and the like. The housing 10 has a conditioning airflow formed therein for conditioning indoor air, or the conditioning airflow is introduced from another path. The conditioning airflow may specifically be a heat exchange airflow, which is used to regulate the temperature of the indoor environment. When the air conditioner is in a refrigerating mode, the heat exchange airflow is cold air; when the air conditioner is in a heating mode, the heat exchange airflow is hot air. Of course, if the air conditioner has additional conditioning functions such as purifying, fresh air, humidifying, etc., the conditioning airflow may also include purifying airflow, fresh air airflow, humidifying airflow, etc.

The housing 10 is provided with a vent 12. In particular, the vent 12 extends through the front wall 101 and at least one lateral side wall 102, 103 of the housing 10 such that the vent 12 is simultaneously open forward and in a lateral direction. The directions referred to herein as "transverse" are already indicated in the figures. For example, in the embodiment shown in fig. 1-5, the vent 12 is made to extend through both lateral side walls 102, 103 of the housing 10. In other embodiments, the vent 12 may extend through only one lateral sidewall 102 or 103.

Each wind deflector 60 stands at a lateral side wall 102, 103 penetrated by the ventilation opening 12. That is, if the vent 12 penetrates the lateral side wall 102 of the left side of the housing 10, one wind deflector 60 is disposed on the left side of the housing 10. If the vent 12 penetrates the right lateral side wall 103 of the housing 10, a wind deflector 60 is provided on the right side of the housing 10. If the ventilation opening 12 penetrates both the left and right lateral side walls 102, 103 of the housing 10, two wind deflectors 60 are provided, respectively, on the left and right sides of the housing 10, as shown in fig. 1 to 5. Preferably, the ventilation opening 12 penetrates through the two lateral side walls 102 and 103 of the casing 10, so that the number of the wind shields 60 is correspondingly two, the drainage air mixing effect is enhanced, and the appearance of the vertical air conditioner indoor unit is more symmetrical.

In the embodiment of the present utility model, each of the wind deflectors 60 has a wind guiding position for guiding the indoor air laterally (left or right) of the housing 10 to the inside of the housing 10 so that the indoor air is mixed into the heat exchange air flow inside the housing 10, as shown in fig. 4 and 5. Fig. 5 illustrates the flow direction of indoor air with open arrows.

Specifically, when the indoor unit of the vertical air conditioner operates, heat exchange air flows blow to the ventilation opening 12 from back to front, and the pressure on two lateral sides of the air flow is reduced, so that a negative pressure area is formed. And, the higher the flow rate, the lower the pressure. Under the action of negative pressure, indoor air at the lateral side of the casing 10 enters the casing from the side of the ventilation opening 12 and is mixed with heat exchange air flow. In this process, the wind deflector 60 serves to guide indoor air, so that drainage of mixed air is achieved. In this way, in the refrigeration mode, the temperature of the mixed air flow is higher than that of the heat exchange air flow, so that a cool and uncooled refrigeration effect is formed; in the heating mode, the temperature of the mixed air flow is lower than that of the heat exchange air flow, so that a heating effect of heat without dryness is formed, the human body feels more comfortable, the circulation of indoor air is promoted, and the refrigerating/heating speed is higher.

In some embodiments, as shown in fig. 4 and 5, each wind deflector 60 is configured to taper away from lateral side walls 102, 103 of housing 10 from front end a to rear end B when in the induced air position. That is, each wind deflector 60 is inclined, so that the wind guiding angle and the included angle of the heat exchange airflow are acute angles, and the indoor air is mixed into the heat exchange airflow at an acute angle, so that the mixing process is smoother, and the mixing air quantity is larger.

In some embodiments, as shown in fig. 1-5, each wind deflector 60 may be movably mounted to the housing 10 so as to rotate to a closed position parallel to the lateral side walls 102, 103 of the housing 10 to shield the vent 12, as shown in fig. 1-3. When the vertical air conditioner indoor unit does not need to conduct drainage and air mixing, the wind shield 60 can be adjusted to the closing position so as to shield the ventilation opening 12 at the lateral side of the ventilation opening 12, and the drainage and air mixing function is closed. The vent 12 is left open only forward and only for air out.

The embodiment of the utility model realizes the opening and closing of the drainage and air mixing function only by enlarging the ventilation opening 12 and adjusting the wind shield 60, has very ingenious conception, has small influence on the appearance of the indoor unit of the vertical air conditioner by the drainage and air mixing structure, has small influence on the internal structures such as the original air duct, the fan and the like, and does not need to excessively adjust the layout of the original components in the shell.

Specifically, each wind deflector 60 may be rotatably mounted to the housing 10 about a vertical axis, and referring to fig. 6, the rotational axes of the two wind deflectors 60 are x1, x2, respectively. In this way, the wind deflector 60 can be rotated to a position where the end a and the end B of the wind deflector 60 are parallel in the front-rear direction or are located obliquely behind the end B, so that the wind deflector 60 guides the heat exchange air flow to be blown out from the lateral side of the ventilation opening 12, and the whole ventilation opening 12 is used for air outlet, thereby enlarging the air outlet angle range of the vertical air conditioner indoor unit.

Each wind deflector 60 may be manually rotated by an operator, or a stepping motor may be provided for each wind deflector 60, and the wind deflector 60 may be rotated by the stepping motor. The stepping motor is electrically connected with a controller of the air conditioner to receive the control of the controller. The user can control the operation state of the stepping motor through a remote controller, a display control panel, a mobile terminal and the like, thereby adjusting the position of the wind shield 60.

In some embodiments, as shown in fig. 3 and 5, the rotational axes x1, x2 of the wind deflector 60 are less distant from the front end a of the wind deflector 60 than from the rear end B of the wind deflector when in the closed position. I.e. x1, x2 are closer to the front end a of the wind deflector 60. So designed, when air is required, the rear end B of the wind deflector 60 can be rotated laterally outward by a larger extent (larger rotation radius, larger rotation radian), while the width of the front end a rotated laterally inward is not large (smaller rotation radius, smaller rotation radian), so that the lateral side of the ventilation opening 12 can be effectively opened, and the influence on the air outlet area of the ventilation opening 12 due to too large width of the front end a of the wind deflector 60.

In some embodiments, as shown in fig. 3, the indoor unit of the floor air conditioner may further include an air guiding device 50. The air guide 50 is provided at a portion of the vent 12 that is open forward for guiding an air outlet direction of the vent 12.

For example, as shown in fig. 3, the air guiding device 50 may include a plurality of swing blades 51 arranged transversely along the casing 10, where each swing blade 51 is in a vertical strip shape and configured to be pivoted about its vertical axis, and the air guiding device 50 is configured to enable the plurality of swing blades 51 to be synchronously pivoted so as to jointly guide the air outlet direction of the air vent 12.

Specifically, the swing blades 51 guide the lateral air outlet direction of the ventilation opening 12, and change the included angle between the air flow direction and the front-rear direction, so that the air flow is blown out frontward, leftward and rightward. In addition, the structure for synchronously rotating each swing blade 51 is very common in the field of air conditioning, and need not be described here.

In some embodiments, each wind deflector 60 may be provided in a vertical bar shape, and the plurality of swing blades 51 of the wind guiding device 50 may be provided in a vertical bar shape. As shown in fig. 1, the widths of the wind deflector 60 and the swing blade 51 are preferably made to coincide so that the user cannot distinguish between them. In this way, the wind shield 60 and the swing blade 51 tend to be consistent in appearance, so that the appearance of the vertical air conditioner indoor unit is better in integrity, more concise and attractive.

Fig. 6 is a schematic view of the indoor unit of the stand air conditioner shown in fig. 1 when the air guide 50 is in a closed state.

In some embodiments, as shown in FIG. 6, the air guide 50 may be configured to allow the plurality of vanes 51 to rotate to a coplanar condition to close the forward opening portion of the vent 12 with the wind deflector 60 in the closed position. When the vertical air conditioner indoor unit is in a stop state, the air guide device 50 and the wind shield 60 can be used for closing the ventilation opening 12 so as to prevent dust and impurities from entering the inside of the shell 10.

In some embodiments, as shown in fig. 3, the floor air conditioner indoor unit further includes an indoor side heat exchanger 20 and a blower fan 30.

The indoor side heat exchanger 20 is disposed in the housing 10, and exchanges heat with the air flow entering the housing 10 from the air inlet 11 to form a heat exchange air flow. Specifically, the air conditioner may perform cooling/heating by a vapor compression refrigeration cycle system. The vapor compression refrigeration cycle system mainly comprises an evaporator, a condenser, a compressor, a throttling device, a four-way valve and the like. During the air conditioning cooling operation, the indoor heat exchanger 20 functions as an evaporator. During the air conditioning operation, the indoor heat exchanger 20 functions as a condenser. The vapor compression refrigeration cycle system switches the flow direction of the refrigerant through the four-way valve, so that the switching between a refrigeration mode and a heating mode is realized, and the specific mode is the prior art in the field of air conditioning and is not needed to be described in detail herein.

A blower 30 is provided in the housing 10 for promoting the flow of air in the housing 10 in a direction outside the housing 10. As shown in fig. 3, the fan 30 may be a cross-flow fan that is vertically disposed (with an axis extending in an up-down direction). A through-flow duct (not shown) may be formed in the housing 10 to match the through-flow fan.

In some alternative embodiments, the indoor side heat exchanger 20 or the fan 30 may not be disposed in the casing 10, and cold air/hot air may be directly introduced from other parts of the air conditioner, and specific implementation manners are well known to those skilled in the art, and need not be described herein.

By now it should be appreciated by those skilled in the art that while a number of exemplary embodiments of the utility model have been shown and described herein in detail, many other variations or modifications of the utility model consistent with the principles of the utility model may be directly ascertained or inferred from the present disclosure without departing from the spirit and scope of the utility model. Accordingly, the scope of the present utility model should be understood and deemed to cover all such other variations or modifications.
