Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are exemplary only for the purpose of explaining the present invention, and should not be construed as limiting the present invention.

An air conditioner according to an embodiment of the present invention is described below with reference to the accompanying drawings. Alternatively, the air conditioner may be a mobile air conditioner.

Referring to fig. 3, 8, 12 and 20, an air conditioner according to an embodiment of the present invention includes: the air duct assembly comprises a shell, an air duct assembly and a heat exchanger 4a, wherein the air duct assembly comprises a shell and a fan assembly.

An accommodating cavity 21a and a rectifying cavity 11a which are communicated with each other are defined in the shell, an air duct inlet 113 communicated with the accommodating cavity 21a is formed on the shell, and an air outlet 111 in the shape of a slit is formed on the wall of one end, far away from the accommodating cavity 21a, of the rectifying cavity 11 a. The fan subassembly is established in the casing of air conditioner, the fan subassembly includes wind wheel 211 and is used for driving the motor 212 of wind wheel 211 pivoted, motor 212 links to each other with wind wheel 211, wind wheel 211 is established and is holding in the chamber 21a, hold chamber 21a and rectification chamber 11a and arrange in the axial direction of wind wheel 211, wind channel import 113 and air outlet 111 are located the axial both sides of wind wheel 211, be formed with the air intake relative and the intercommunication with wind channel import 113 on the casing of air conditioner, make air intake and air outlet 111 be located the axial both sides of wind wheel 211 from this. The heat exchanger 4a is arranged in the casing of the air conditioner and located at the upstream of the fan assembly, and the heat exchanger 4a and the fan assembly are arranged along the axial direction of the wind wheel 211.

When the air conditioner works, the motor 212 drives the wind wheel 211 to rotate, airflow enters the shell of the air conditioner from the air inlet and enters the shell through the air duct inlet 113, and after exchanging heat with the heat exchanger 4a, the airflow sequentially flows through the accommodating cavity 21a and the rectifying cavity 11a and is discharged to the indoor space from the air outlet 111, so that the indoor environment temperature can be improved. During the process of the air flow flowing through the rectification chamber 11a, the air flow can be rectified, so that the air flow is more orderly. The air current is discharged to the indoor from being the air outlet 111 of slit form after the rectification of rectification chamber 11a, under the condition that the power and the rotational speed of wind wheel 211 are the same, can increase air supply distance for the air supply is farther, plays better refrigeration/heating effect, and energy consumption and noise are all lower.

Most of the housing may be located inside the casing, and a portion of the housing adjacent to the air outlet 111 may be located outside the casing.

The air outlet 111 may be oriented to direct air out, and the air outlet 111 may also be oriented to direct air out forwards and obliquely upwards.

Alternatively, the outlet 111 may extend linearly or curvilinearly. For example, the outlet 111 may have a shape of a long strip, an arc, or a ring (e.g., a circular ring, an elliptical ring, a polygonal ring, etc.).

According to the principle that Q (air volume) is S (air outlet area) V (air speed), the smaller the air outlet area is, the larger the air outlet speed is under the same air volume, so that the air can be sent farther under the same air volume, and the better cooling/heating effect is achieved. Meanwhile, according to bernoulli's equation, for an incompressible fluid, there are: ρ gh +0.5 ρ v²+ p ═ C, i.e.: the energy + kinetic energy + pressure potential energy in gravity is constant. For gases, gravitational potential energy is negligible, so the higher the kinetic energy, the lower the pressure. Therefore, for high-speed jet flow, obvious low pressure is formed in the jet flow area, and the low pressure can form an adsorption traction effect on surrounding air, so that the total airflow flow is increased, and the effect of long-distance air supply can be further achieved.

Alternatively, wind wheel 211 may be a centrifugal wind wheel, whereby the blowing distance may be further increased. When the wind wheel 211 is a centrifugal wind wheel, the air outlet 111 can discharge air along the axial direction of the wind wheel 211. Specifically, external air flow enters the casing through an air inlet of the air conditioner, enters the casing through the air duct inlet 113, exchanges heat with the heat exchanger 4a, is radially thrown out of the wind wheel 211 after being pressurized by the wind wheel 211, and is changed into a backward direction through the accommodating cavity 21a and the rectifying cavity 11a, and is ejected out of the air outlet 111. In the process that the airflow flows to the rectification cavity 11a from the accommodating cavity 21a, the airflow changes the direction from the radial direction of the wind wheel 211 to the axial direction of the wind wheel 211, the axial direction of the wind wheel 211 can extend along the front-back direction, the forward air supply can be realized at the moment, and the backward airflow can be more orderly under the rectification action of the rectification cavity 11a, so that the airflow loss is reduced.

Optionally, when the wind wheel 211 is a centrifugal wind wheel, at least a portion of the rectification cavity 11a adjacent to the accommodating cavity 21a may be in a ring shape extending around the central axis of the wind wheel 211, so that the airflow pressurized by the wind wheel 211 is radially thrown out of the wind wheel 211 and turns backward, and the airflow of each portion in the circumferential direction of the wind wheel 211 may directly flow into the rectification cavity 11a, thereby reducing the flow loss.

In addition, the air duct inlet 113 and the air outlet 111 are arranged on two axial sides of the wind wheel 211, and meanwhile, the air inlet formed on the casing is arranged opposite to the air duct inlet 113, so that the air inlet and the air outlet 111 are arranged on two axial sides of the wind wheel 211, and airflow can generally flow along the axial direction of the wind wheel 211 in the process of flowing through the internal space of the air conditioner, so that the flow path of the airflow is simple, the flow path of the airflow can be reduced, the flow loss of the airflow is reduced, the airflow is blown out farther, and the mutual interference and influence of the airflow between the air inlet and the air outlet 111 can be reduced.

Alternatively, referring to fig. 3, 8, 12 and 20, the heat exchanger 4a may be a flat plate, thereby making the structure of the heat exchanger 4a simple and easy to manufacture, and ensuring that the heat exchanger 4a has a large heat exchange area, the heat exchange amount and the heat exchange effect, and making the structure of the whole air conditioner simple and compact. For example, the heat exchanger 4a may be disposed substantially perpendicular to the central axis of the wind wheel 211. When the air conditioner works, airflow enters the shell from the air inlet of the air conditioner and enters the shell from the air duct inlet 113 to exchange heat with the flat-plate-shaped heat exchanger 4a, and the airflow passes through the heat exchanger 4a and sufficiently exchanges heat with the heat exchanger 4a, so that a large heat exchange area is formed between the airflow and the heat exchanger 4a, and the heat exchange effect is ensured.

According to the air conditioner provided by the embodiment of the utility model, the air outlet 111 is arranged in a slit shape, and the air flow is ejected out through the air outlet 111 and can be blown to a farther place, so that a better cooling/heating effect is achieved, and the energy consumption and the noise are both lower; meanwhile, the air duct inlet 113 and the air outlet 111 are arranged on two axial sides of the wind wheel 211, so that the flow path of the air flow can be reduced, the flow loss of the air flow can be reduced, the air flow can be blown out farther, and the mutual interference and influence of the air flow between the air inlet and the air outlet 111 can be reduced.

According to some embodiments of the present invention, referring to fig. 3, 8, 12 and 20, the rectifying cavity 11a includes a first sidewall 111b and a second sidewall 112b extending along a length direction of the air outlet 111, the first sidewall 111b and the second sidewall 112b are disposed opposite and spaced apart, the air outlet 111 is defined between a free end of the first sidewall 111b and a free end of the second sidewall 112b, a distance W between the first sidewall 111b and the second sidewall at the air outlet 111 is not greater than 0.05D, and D is a diameter of the wind wheel 211. Therefore, the air outlet of the air outlet 111 can be ensured to have higher air outlet speed, so that the air conditioner can be ensured to supply air to a far place.

According to some embodiments of the present invention, the length range of the air outlet 111 is 0.5D-8D, said D being the diameter of the wind wheel 211. For example, when the outlet 111 is annular, the length of the outlet 111 is the circumference of the outlet 111; when the outlet 111 is in a strip shape, the length of the outlet 111 is the extending length of the outlet 111. Therefore, the air outlet 111 has a larger air outlet speed, and meanwhile, the air outlet area can be ensured, so that the air conditioner has a larger air outlet range, and the refrigerating/heating performance of the air conditioner is further improved.

According to some embodiments of the present invention, referring to fig. 3, 8, 12 and 20, in the axial direction of the wind wheel 211, the distance between the trailing edge of the blade of the wind wheel 211 and the air outlet 111 is D, the value range of D is 0.1D-1.5D, D is the diameter of the wind wheel 211. Therefore, after the airflow passes through the wind wheel 211 and before the airflow exits the air outlet 111, the airflow has enough flowing distance to adjust the flowing direction of the airflow and make the airflow more orderly, and the flow loss is reduced. Also, while the airflow becomes more orderly in the rectification chamber 11a, the flow path of the airflow in the rectification chamber 11a can be made shorter, so that the flow resistance and flow loss are smaller.

According to some embodiments of the present invention, referring to fig. 3, 8, 12 and 20, the housing includes a first housing 1a and a second housing 2a connected, the first housing 1a includes a first rectifying case 111c, a second rectifying case 112c and a baffle 113c, the first rectifying case 111c and the second rectifying case 112c may be cylindrical or conical, and the baffle 113c may be substantially perpendicular to the rotation axis of the wind wheel 211. The first rectifying case 111c is disposed around the outer circumference of the baffle 113c and the first rectifying case 111c is connected to the baffle 113c, the baffle 113c is located at one end of the first rectifying case 111c adjacent to the second case 2a, the second rectifying case 112c is disposed around the outer circumference of the first rectifying case 111c, a support member is disposed between the second rectifying case 112c and the first rectifying case 111c to space the second rectifying case 112c from the first rectifying case 111c, and both ends of the support member are respectively connected to the second rectifying case 112c and the first rectifying case 111c, the second rectifying case 112c, and the baffle 113c together define the rectifying chamber 11a, the second case 2a has a cylindrical shape and defines the accommodating chamber 21a, the second case 2a may have a cylindrical shape, and the second rectifying case 112c is connected to the second case 2 a. After the airflow flows into the accommodating cavity 21a and is pressurized by the wind wheel 211, the airflow can be radially thrown out by the wind wheel 211, meanwhile, the baffle 113c can prevent the airflow from diverging along the axial direction when flowing through the wind wheel 211, meanwhile, the rectifying cavity 11a and the accommodating cavity 21a are convenient to form, and the structure of the shell is simple.

The first sidewall 111b may be a part of the first rectifying case 111c, and the second sidewall 112b may be a part of the second rectifying case 112c (see fig. 1 to 17); the first side wall 111b and the second side wall 112b may be both part of the second rectification case 112c (refer to fig. 18 to 21).

Alternatively, referring to fig. 3, 8, 12 and 20, one side of the rectification cavity 11a facing the accommodating cavity 21a is opened to communicate with the accommodating cavity 21a, the airflow flows out in the radial direction of the wind wheel 211 after flowing through the wind wheel 211, the flow direction of the airflow is changed from the radial direction of the wind wheel 211 to be substantially in the axial direction of the wind wheel 211 during the process that the airflow flows into the rectification cavity 11a from the accommodating cavity 21a, and the airflow is blown out through the air outlet 111 after flowing through the rectification cavity 11 a. Therefore, the airflow inlet of the rectification cavity 11a has larger space and area, and airflow can directly flow into the rectification cavity 11a through the accommodating cavity 21a after flowing through the wind wheel 211, so that airflow flowing loss is reduced.

According to some embodiments of the present invention, referring to fig. 3, 8, 12 and 20, the flow area of the rectification chamber 11a is gradually reduced in the flow direction of the air flow. Therefore, in the process of rectifying the airflow flowing through the rectifying cavity 11a, the flow speed of the airflow can be gradually increased in the flowing direction of the airflow, so that the airflow flows out of the air outlet 111 at a higher speed, and the air supply distance of the air conditioner is further increased.

According to some embodiments of the present invention, referring to fig. 8, 10 and 18, at least one set of guide blade set is disposed in the rectification cavity 11a, for example, a set of guide blade set may be disposed, and a plurality of sets of guide blade sets may also be disposed. Each guide vane group comprises a plurality of guide vanes 13a, each group of the plurality of guide vanes 13a is arranged at intervals along the circumferential direction of the rectifying cavity 11a, and each guide vane 13a can be connected with the inner wall of the rectifying cavity 11a to fix the guide vane 13a in the rectifying cavity 11 a. When the guide vane groups are multiple groups, the multiple groups of guide vane groups are arranged at intervals along the flowing direction of the airflow. Therefore, by the guide vanes 13a, in the process of flowing the airflow through the rectification cavity 11a, the guide vanes 13a can further rectify the airflow, so that the airflow becomes more orderly, and the airflow loss is reduced. The number of the guide vane groups can be set according to the size of the rectifying cavity 11a and the distance of the airflow flowing through the rectifying cavity 11a, so that the guide vane 13a has relatively small airflow flowing resistance while the guide vane groups play a good rectifying role in the airflow, and a relatively good comprehensive effect is achieved.

When the casing includes the first casing 1a and the second casing 2a connected to each other, and the first casing 1a includes the first rectifying casing 111c, the second rectifying casing 112c, and the baffle 113c, the guide vane 13a is disposed in the rectifying cavity 11a, and both ends of the guide vane 13a are connected to the second rectifying casing 112c and the first rectifying casing 111c, respectively, and at this time, the guide vane 13a may serve as the support member. Thereby, the guide vane 13a can perform both the rectifying function and the function of spacing the second rectifying shell 112c and the first rectifying shell 111c apart.

In the present invention, "a plurality" means two or more.
