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.
However, when the existing air conditioner needs to perform rapid cooling/heating, the air quantity of the fan is sometimes required to be increased, the air outlet temperature is reduced (cooling) or the air outlet temperature is increased (heating), which can cause the human body to feel that the hot air/cold air is forcefully and directly blown, so that the human body feel uncomfortable.
Disclosure of Invention
The utility model aims to overcome or at least partially solve the problems and provide a vertical air conditioner indoor unit with more comfortable cold air or hot air temperature.
The utility model further aims to improve the integration degree of the mixed flow air-inducing structure and the existing structure of the indoor unit of the vertical air conditioner and reduce the influence of the flow-inducing air-mixing structure on the structure of the indoor unit of the vertical air conditioner.
Particularly, the utility model provides a vertical air conditioner indoor unit, which comprises a shell, wherein a heat exchange air outlet is formed in the front of the shell and used for blowing heat exchange air flow to an indoor environment;
the heat exchange air flow device comprises a shell, and is characterized in that at least one air mixing air duct is formed in the shell, and an air mixing outlet and an air mixing inlet which are communicated with the air mixing air duct are respectively formed in the front part and the lateral side part of the shell, so that when heat exchange air flow outwards flows from the heat exchange air outlet, indoor air in the air mixing air duct is mixed into the heat exchange air flow under the action of negative pressure.
Optionally, the number of the air mixing channels is two; and is also provided with
The air mixing outlets of the two air mixing channels are respectively positioned at two lateral sides of the heat exchange air outlet, and the air mixing inlets of the two air mixing channels are respectively positioned at two lateral sides of the shell.
Optionally, in a direction from the air mixing inlet to the air mixing outlet, the air mixing duct extends forward and obliquely toward a lateral center direction of the housing.
Optionally, a grille is disposed at each air mixing outlet, and is used for guiding indoor air in the air mixing duct to the heat exchange airflow.
Optionally, at least one air mixing fan is arranged in each air mixing duct.
Optionally, a plurality of air mixing fans are arranged in each air mixing duct, the air mixing fans are arranged at intervals along the vertical direction, and each air mixing fan is an axial flow fan.
Optionally, each air mixing fan is arranged at the air mixing inlet.
Optionally, a grille is arranged at each air mixing inlet, and each air mixing fan is mounted on the grille.
Optionally, the vertical air conditioner indoor unit further includes a wind mixing housing, which includes a top wall, a bottom wall, a front wall and a rear wall, so as to enclose the wind mixing duct together, the wind mixing housing is detachably installed in the housing, and an inlet and an outlet are respectively opposite to the wind mixing outlet.
Optionally, the ratio of the air outlet area of the air mixing outlet to the air inlet area of the air mixing inlet of each air mixing duct is less than 0.9.
In the vertical air conditioner indoor unit, the air mixing duct is formed in the shell and is used for introducing indoor air, so that the indoor air flows out from the air mixing outlet of the air mixing duct. Therefore, when the vertical air conditioner indoor unit operates, heat exchange airflow flows outwards from the heat exchange air outlet, so that the peripheral pressure of the heat exchange airflow is reduced, the higher the flow speed is, the lower the pressure is, and a negative pressure area is formed. Under the negative pressure, indoor air in the air mixing duct is mixed into heat exchange airflow to form a drainage air mixing structure. 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 addition, the air mixing duct is arranged in the shell, the air mixing inlet and the air mixing outlet are both formed in the shell, and the air mixing shell is detachably arranged in the shell. 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 the original air duct fan and the like, and does not need to excessively adjust the layout of the internal components of the shell.

The embodiment of the utility model provides a vertical air conditioner indoor unit which is an indoor part of a split vertical air conditioner. The air conditioner is used for conditioning indoor air, including adjusting temperature, humidity, air quality of the air, humidifying the indoor air, dehumidifying, introducing fresh air, and the like. The air conditioner may be constituted by an evaporator, a condenser, a compressor, a throttle device and other necessary elements to form a vapor compression refrigeration cycle system to output cool/hot air through a fan to achieve cooling and heating of an indoor environment.
Fig. 1 is a schematic structural view of an indoor unit of a stand air conditioner according to an embodiment of the present utility model; FIG. 2 is an enlarged view at A of FIG. 1; fig. 3 is a schematic cross-sectional view of a floor air conditioner indoor unit according to one embodiment of the present utility model.
As shown in fig. 1 to 3, the indoor unit of a floor air conditioner according to an embodiment of the present utility model includes a housing 10. The front part of the housing 10 is provided with a heat exchange air outlet 12 for blowing out heat exchange air flow to the indoor environment so as 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 and fresh air, the heat exchange air outlet 12 may also be used to blow out the conditioning air flow such as purified air flow and fresh air flow.
At least one air mixing duct 600 is formed inside the housing 10. The front and lateral sides (i.e., left/right sides) of the housing 10 are respectively provided with a mixing air outlet 14 and a mixing air inlet 13, which are communicated with the mixing air duct 600, so that when the heat exchange air flow outwardly flows from the heat exchange air outlet 12, the indoor air in the mixing air duct 600 is mixed into the heat exchange air flow by means of negative pressure. Specifically, fig. 3 illustrates the flow direction of indoor air with open arrows, and illustrates the flow direction of heat exchange air flow with ordinary arrows. Indoor air enters the air mixing duct 600 from the side (left/right) of the casing 10 through the air mixing inlet 13, flows out through the air mixing outlet 14, and is mixed into the heat exchange air flow flowing forward.
In the indoor unit of the vertical air conditioner according to the embodiment of the present utility model, the air mixing duct 600 is formed inside the casing 10, and is used for introducing indoor air, so that the indoor air flows out from the air mixing outlet 14 of the air mixing duct 600. Thus, when the indoor unit of the vertical air conditioner is operated, the heat exchange air flows outwards from the heat exchange air outlet 12, so that the peripheral pressure is reduced, the higher the flow speed is, the lower the pressure is, and a negative pressure (the pressure is lower than the indoor atmospheric pressure and is called as negative pressure) area is formed. Under the negative pressure, indoor air in the air mixing duct 600 is mixed into the heat exchange airflow to form a drainage air mixing structure. 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 addition, in the embodiment of the utility model, the air mixing duct 600 is arranged in the shell 10, the air mixing inlet 13 and the air mixing outlet 14 are both arranged in the shell 10, the drainage air mixing structure has small influence on the appearance of the indoor unit of the vertical air conditioner, and the influence on the internal structures such as the original duct and the fan is also small, so that the layout of the internal components of the shell 10 is not required to be adjusted too much.
In some embodiments, as shown in fig. 1 to 3, an indoor heat exchanger 20, a blower 30 may be provided within the housing 10. The rear of the housing 10 may be provided with an air inlet 11. The indoor heat exchanger 20 and the throttle device are connected with a compressor, an outdoor heat exchanger and other refrigerating elements arranged in the air conditioner outdoor unit through pipelines to form a vapor compression refrigeration cycle system. Under the action of the fan 30, indoor air enters the shell 10 through the air inlet 11, forms heat exchange airflow after forced convection heat exchange with the indoor heat exchanger 20, and flows out of the heat exchange air outlet 12 through the guidance of an air duct. An air guiding device 50 may be mounted at the heat exchange air outlet 12, for example, comprising a plurality of swing blades rotatable about a vertical axis, so as to adjust the air outlet direction of the heat exchange air outlet 12.
In some embodiments, the ratio of the air outlet area of the air mixing outlet 14 to the air inlet area of the air mixing inlet 13 of each air mixing duct 600 may be less than 0.9, preferably less than 0.85, so that the indoor air can flow out of the air mixing outlet 14 at a fast flow rate, and the air mixing quantity is larger.
Fig. 4 is a schematic structural view of a mixing air case 60 in a vertical air conditioner indoor unit according to an embodiment of the present utility model.
In some embodiments, as shown in fig. 4, the floor air conditioner indoor unit may further comprise at least one air mixing shell 60. Each mixing housing 60 includes a top wall 61, a bottom wall 62, a front wall 64, and a rear wall 63. The top wall 61, the bottom wall 62, the front wall 64, and the rear wall 63 collectively enclose a mixing duct 600. Each of the mixing wind shells 60 is detachably installed in the housing 10, and its inlet and outlet are opposite to one mixing wind inlet 13 and one mixing wind outlet 14, respectively.
In this embodiment, the air mixing housing 60 is designed as an independent component, and the original structures such as a framework and an air duct inside the housing 10 do not need to be redesigned, which is beneficial to realizing the generalization of the components of the product.
In some embodiments, as shown in fig. 1 to 3, the number of the air mixing duct 600 may be two. And the air mixing outlets 14 of the two air mixing channels 600 are respectively positioned at two lateral sides of the heat exchange air outlet 12, and the air mixing inlets 13 of the two air mixing channels 600 are respectively positioned at two lateral sides of the shell 10. The scheme fully utilizes the space on two sides of the heat exchange air outlet 12, so that the air mixing quantity is larger, and the appearance of the indoor unit of the vertical air conditioner is more symmetrical and attractive. Furthermore, since two air mixing ducts 600 are provided, it is not necessary to design each air mixing duct 600 excessively large, and the influence on the existing structure inside the casing 10 is further reduced.
Further, as shown in fig. 3, the air mix duct 600 extends forward and obliquely toward the lateral center direction of the housing 10 in the direction from the air mix inlet 13 to the air mix outlet 14. That is, the left air mix duct 600 is extended rightward and forward, and the right air mix duct 600 is extended leftward and forward. The design can enable the air outlet flow of the air mixing duct 600 to flow obliquely and forwards, and the air outlet flow is converged into the heat exchange air flow at a better angle.
In some embodiments, as shown in FIG. 2, a grille may be provided at each of the air mixing outlets 14 for directing the indoor air within the air mixing duct 600 to the heat exchange airflow. Further, the grille bars of the grille may be made rotatable about a vertical axis so as to adjust the mixing angle of the indoor air, thereby changing the mixing amount (the volume of the indoor air mixed into the heat exchange air flow).
In some embodiments, as shown in fig. 1 and 3, at least one air mixing fan 80 may be disposed within each air mixing duct 600. After the air mixing fan 80 is started, the indoor air flow can be promoted, the indoor air mixing amount is increased, and the air mixing effect is more obvious.
Further, as shown in fig. 1 and 3, a plurality of air mixing fans 80 may be disposed in each air mixing duct 600, and the plurality of air mixing fans 80 may be arranged at intervals in the vertical direction. The air volume of each air mixing fan 80 can be independently adjusted, so that the air conditioner can selectively turn on/off the air mixing fans 80 with corresponding heights or adjust the rotating speed of the air mixing fans 80 according to the air flow temperature distribution in the height direction of the indoor space, and the air mixing can be carried out by mainly introducing the air flow with a larger temperature difference with the heat exchange air flow. Each of the air mixing fans 80 is an axial flow fan.
In some embodiments, as shown in fig. 1 and 3, each of the air mixing fans 80 may be disposed at the air mixing inlet 13. Specifically, a grill may be provided at each of the air mixing inlets 13, to which each of the air mixing fans 80 is mounted.
In the description of the present embodiment, a description referring to the terms "one embodiment," "some embodiments," "illustrative embodiments," "examples," "specific examples," or "some examples," etc., means that a particular feature, structure, material, or characteristic described in connection with the embodiment or example is included in at least one embodiment or example of the present utility model. In this specification, schematic representations of the above terms do not necessarily refer to the same embodiments or examples. Furthermore, the particular features, structures, materials, or characteristics described may be combined in any suitable manner in any one or more embodiments or examples.
