The utility model mainly provides an indoor set of air conditioning, the form of indoor set of air conditioning can have a lot, like the indoor set of wall-hanging air conditioning, indoor set of floor type air conditioning etc.. The main point is to adjust the position relationship between the air outlet direction of the volute 210 and the indoor heat exchanger 500, so that the airflow can extend along the surface of the heat exchanger and pass through the heat exchanger, thereby improving the heat exchanger efficiency of the airflow and the heat exchanger.
The following will mainly describe a specific structure of the air conditioning indoor unit.
Referring to fig. 1 to 11, in an embodiment of the present invention, the indoor unit of an air conditioner includes:
a housing 100, the housing 100 having a mounting cavity;
a volute 210, wherein the volute 210 is installed in the installation cavity, and an air outlet 250 of the volute 210 is arranged in an inclined manner towards the bottom of the installation cavity;
the first heat exchanger 510 is installed in the installation cavity corresponding to the air outlet, the first heat exchanger 510 extends from bottom to top to the top of the volute 210, so as to form an air inlet cavity by enclosing among the volute 210, the first heat exchanger 510 and the bottom of the installation cavity.
Specifically, in the present embodiment, the air conditioning indoor unit is described by taking an air duct unit as an example. The overall shape of the housing 100 may be many, such as a cuboid (on the basis of a cuboid, a recess, a protrusion, and an opening are provided according to actual needs), a cylinder, and the like. The housing 100 has an air inlet, an air outlet, and an air duct communicating the air inlet and the air outlet. The fan 200 and the indoor heat exchanger 500 are both mounted in a mounting cavity, which in some embodiments is part of an air duct. The indoor unit of the air conditioner includes the first heat exchanger 510, and in some embodiments, may also include a plurality of heat exchangers, such as the first heat exchanger 510 and the second heat exchanger 520. The first heat exchanger 510 and the second heat exchanger 520 may be disposed in the refrigerant circuit in parallel, or may be disposed in the refrigerant circuit in series. No matter the first heat exchanger 510 and the second heat exchanger 520 are connected in series or in parallel, the working modes of the first heat exchanger 510 and the second heat exchanger 520 can be different or the same by arranging a reasonable outdoor refrigerant flow path, that is, the first heat exchanger 510 and the second heat exchanger 520 can simultaneously refrigerate and simultaneously heat; one can also refrigerate and the other can heat.
The blower 200 includes a volute 210 and a wind wheel 220 disposed in the volute 210, and the motor 230 drives the wind wheel 220 to rotate, so as to form a negative pressure region and a positive pressure region in the volute 210, such that the air enters the volute 210 from an air inlet of the volute 210 and exits the volute 210 from an air outlet 250 of the volute 210. The volute 210 includes a curved surface portion and a straight surface portion, which are enclosed to form an accommodating chamber for accommodating the wind wheel 220, and an air outlet duct communicated with the accommodating chamber. The air outlet is positioned at one end of the air outlet duct far away from the accommodating cavity. The orientation of the air outlet determines the direction of the air outlet of the volute 210. The direction of the air outlet of the volute 210 is inclined towards the bottom of the installation cavity, so that the air outlet direction of the volute 210 is inclined towards the bottom of the installation cavity and is blown out.
There are many ways to achieve the downward inclination of the outlet 250, and an example will be described below.
The top of the volute 210 has a curved surface shell section 211 and a straight surface shell section 212 connected to the curved surface shell section 211, and the straight surface shell section 212 is inclined downward compared to the tangent plane at the top end of the curved surface shell section 211. Thus, when the airflow flows out from the air outlet duct, the airflow flows along the curved surface shell section 211 of the volute 210 first, and then flows along the straight surface shell section 212 of the volute 210, so that the airflow is downward inclined to flow out. The curved surface shell section 211 and the straight surface shell section 212 are in smooth transition, so that the airflow can smoothly flow out in a downward inclination mode.
The first heat exchanger 510 extends from bottom to top towards the top of the volute 210, so that the first heat exchanger 510 is obliquely arranged in the mounting cavity, and the higher side of the first heat exchanger is close to the top of the volute 210, and the lower side of the first heat exchanger is close to the bottom of the mounting cavity, or even is directly connected with the bottom of the mounting cavity. In this manner, the air flow blown out from the scroll 210 has a component extending along the air intake side of the first heat exchanger 510, so that the air flow sufficiently passes through the respective positions of the first heat exchanger 510. Meanwhile, an air inlet cavity is formed by enclosing among the volute 210, the first heat exchanger 510 and the bottom of the installation cavity, so that the air flow flowing out of the volute 210 is discharged from the air outlet of the air duct only after passing through the first heat exchanger 510, that is, the air flow needs to exchange heat with the first heat exchanger 510.
In this embodiment, the air outlet 250 of the volute 210 is inclined toward the bottom of the installation cavity, and meanwhile, the first heat exchange is inclined along the inclination trend of the air outlet 250 of the volute 210, so that the airflow flowing out of the volute 210 has a component flowing along the air inlet side of the first heat exchanger 510, and the airflow can be distributed on the air inlet side of the first heat exchanger 510 and passes through the first heat exchanger 510 under the action of the horizontal component of the airflow, thereby greatly improving the heat exchange time and the heat exchange efficiency of the air and the first heat exchanger 510, and being beneficial to improving the energy efficiency of the air conditioner; meanwhile, since the air outlet of the volute 210 is inclined downwards, the downward inclination angle of the first heat exchanger 510 can be reduced (the included angle between the downward inclination angle and the bottom of the housing 100 is increased), so that the installation of the first heat exchanger 510 is facilitated (the horizontal distance between the gravity center of the first heat exchanger 510 and the supporting position of the bottom of the first heat exchanger 510 is reduced); through setting up first heat exchanger 510 slope, be favorable to increasing first heat exchanger 510 heat transfer area to improve the heat exchanger rate.
In some embodiments, in order to ensure the air flow flowing along the air inlet side of the first heat exchanger 510 and fully spreading the first heat exchanger 510, the direction of the air outlet 250 of the volute 210 and the inclined direction of the first heat exchanger 510 are arranged at an included angle of 135 ° to 150 °. Within this angle, the airflow from the volute 210 can be ensured to be distributed over the first heat exchanger 510, and not a large amount of airflow is blown directly to the bottom of the installation cavity. When the included angle is smaller than 135 °, the airflow flowing out of the volute 210 is difficult to be distributed on the air inlet side of the first heat exchanger 510, so that the airflow passing through the bottom of the first heat exchanger 510 is too small, and the utilization rate of the bottom of the first heat exchanger 510 is reduced; when the included angle is larger than 150 °, part of the airflow flowing out of the volute 210 flows to the bottom of the air duct, so that the air passing through the bottom of the first heat exchanger 510 is too much, the heat exchange effect is changed, and the utilization rate of the upper part of the first heat exchanger 510 is reduced.
There are various combinations for realizing the arrangement of the included angle of 135-150 ° between the direction of the air outlet 250 of the volute 210 and the inclined direction of the first heat exchanger 510, which are illustrated below by way of example:
the top of the volute 210 is provided with a curved surface shell section 211 and a straight surface shell section 212 connected with the curved surface shell section 211, an included angle α of 5-10 degrees is formed between the straight surface shell section 212 and a tangent plane at the top end of the curved surface shell section 211, and/or an included angle β of 40-50 degrees is formed between the first heat exchanger 510 and the bottom of the installation cavity.
The included angle between the tangent planes at the top ends of the straight-surface shell section 212 and the curved-surface shell section 211 is not too small, and when the included angle is smaller than 5 degrees, the first heat exchanger 510 must deflect by a large angle to meet the better heat exchange efficiency, so that the installation of the first heat exchanger 510 is not facilitated, the width and the size occupied by the first heat exchanger 510 are increased, and the reasonable utilization of the space is not facilitated. It should not too big yet, when the contained angle is greater than 10, the tangent plane at the skew curved surface shell section 211 top of straight-sided casing is too much, will make the air current flow to the straight section of curved surface from curved surface shell section 211, produces great skew, causes the wind pressure loss of air current too big, is unfavorable for fan 200's high-efficient work.
The included angle between the first heat exchanger 510 and the bottom of the installation cavity is not too small, and when the included angle is smaller than 40 degrees, the distance from the lower end of the first heat exchanger 510 to the air outlet of the volute 210 is relatively long, so that the airflow in the volute 210 is not facilitated to flow to the bottom of the air inlet side of the first heat exchanger 510, and the utilization rate of the bottom of the first heat exchanger 510 is reduced; meanwhile, the installation of the first heat exchanger 510 is not facilitated, and the width dimension occupied by the first heat exchanger 510 is increased, which is not beneficial to the reasonable utilization of space. The included angle should not be too large, and when the included angle is larger than 50 °, the heat exchange area of the first heat exchanger 510 will be reduced, and meanwhile, the time for the air to flow out of the volute 210 and pass through the upper part of the first heat exchanger 510 will be shortened, which is not favorable for the air flow to exchange heat with the first heat exchanger 510.
Regarding the second heat exchanger 520, the indoor unit of the air conditioner further includes the second heat exchanger 520, and the second heat exchanger 520 and the first heat exchanger 510 are connected in series or in parallel in a refrigerant loop of the air conditioner; the second heat exchanger 520 is located on a side of the first heat exchanger 510 facing away from the volute 210. When the first heat exchanger 510 refrigerates and the second heat exchanger 520 heats, the indoor unit of the air conditioner can realize dehumidification and reheating, and can perform dehumidification treatment on air under the condition that the temperature change does not affect the use of a user. The second heat exchanger 520 is disposed at a side of the first heat exchanger 510 facing away from the scroll 210, so that the air flow is dehumidified and reheated first, which is beneficial to improving the dehumidification efficiency. The second heat exchanger 520 is disposed at an angle γ with respect to the bottom of the housing 100, where γ is, for example, 90.
