Description

Technical Field

[0001] The present invention relates to the technical field of air conditioning, and in particular to an air conditioning outdoor unit and an air conditioner. Background Art

[0002] In the outdoor unit of the air conditioner, a partition plate is used to separate the outdoor unit cavity into a heat exchange cavity and a compressor cavity. In the heat exchange cavity, an axial flow fan is often used to perform forced convection heat exchange on the heat exchanger.

The motor bracket is fixed to the chassis, the motor is fixed to the motor bracket by screws, the fan blades are fixed to the extended shaft of the motor, and part of the axial flow fan blades extends into the guide ring of the front panel, and the grille on the outer cover flows the air out.

[0003] However, the fan system of the existing air-conditioning outdoor unit is composed of many parts and the assembly positioning accuracy is poor. After the fan blades are extended into the guide ring, the axial coaxiality between the fan blades and the guide ring is poor, resulting in uneven gap between the fan blades and the cylindrical surface of the guide ring when the fan blades rotate. In addition, the grille structure of the outer cover will hinder the flow of air.

DETAILED DESCRIPTION

[0042] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0043] As mentioned in the background technology, the internal structure of the existing air conditioner outdoor unit, such as Figures 16 to 18 As shown, it usually includes structures such as a fan system, a guide ring, a motor bracket 230 and an air outlet grille. The guide ring and the air outlet grille are arranged correspondingly, the fan system is arranged on the motor bracket, and some blades of the fan system extend into the guide ring, so that the airflow is blown out through the air outlet grille under the guiding effect of the guide ring; however, in the above structure, the coaxiality of the fan system and the guide ring is poor, the gap between the blade and the guide ring is uneven during the rotation of the blade, and the air outlet direction of the air outlet grille is single, which will block the airflow, resulting in high noise during the operation of the air conditioner outdoor unit and poor user comfort experience. Therefore, in response to the above-mentioned problems, in the air-conditioning outdoor unit provided in the present application, the fan assembly 200 is connected to the air outlet grille 300, and the motor bracket 230 is eliminated. At the same time, since the air outlet grille 300 and the guide portion 110 are located on the same side of the fan assembly 200, part of the fan assembly 200 extends into the guide portion 110, which is beneficial to the coaxiality between the fan assembly 200 and the guide portion 110. The air outlet grille 300 is provided with a first air outlet portion 310 and a second air outlet portion 320, and there is an angle between the extension direction of the first air outlet portion 310 and the extension direction of the second air outlet portion 320, so that the airflow is blown out in different directions, thereby reducing the airflow disturbance problem caused by the obstruction of the air outlet grille 300 to the airflow, reducing the noise of the air-conditioning outdoor unit during operation, and improving the user comfort.

[0044] Please refer to Figures 1 to 15The present application provides an air conditioner outdoor unit, comprising: a casing 100, in which an air guide portion 110 is arranged; a fan assembly 200, which is arranged in the casing 100, and a part of the fan assembly 200 extends into the air guide portion 110; an air outlet grille 300, which is arranged on the casing 100 and opposite to the air guide portion 110, and the fan assembly 200 is connected to the air outlet grille 300; wherein the air outlet grille 300 has a first air outlet portion 310 and a second air outlet portion 320, and an extension direction of the first air outlet portion 310 and an extension direction of the second air outlet portion 320 have an included angle, and the airflow guided out by the air guide portion 110 is blown out by the first air outlet portion 310 and the second air outlet portion 320 respectively.

[0045] The air conditioner outdoor unit provided according to the present application includes a casing 100, a fan assembly 200 and an air outlet grille 300, wherein an air guide portion 110 is arranged in the casing 100; the fan assembly 200 is arranged in the casing 100, and a portion of the fan assembly 200 extends into the air guide portion 110; the air outlet grille 300 is arranged on the casing 100 and opposite to the air guide portion 110, and the fan assembly 200 is connected to the air outlet grille 300; wherein the air outlet grille 300 has a first air outlet portion 310 and a second air outlet portion 320, and an extension direction of the first air outlet portion 310 and an extension direction of the second air outlet portion 320 have an angle, and the airflow derived from the air guide portion 110 is blown out by the first air outlet portion 310 and the second air outlet portion 320 respectively. By connecting the fan assembly 200 with the air outlet grille 300, the matching accuracy between the fan assembly 200 and the guide portion 110 can be easily adjusted during the assembly process of the fan assembly 200. At the same time, the air outlet grille 300 is provided with a first air outlet portion 310 and a second air outlet portion 320, so that the airflow can flow out in different directions, which not only improves the outflow range of the airflow, but also reduces the airflow disturbance caused by the air outlet grille 300 blocking the airflow, thereby improving the energy efficiency of the air conditioner outdoor unit, reducing the noise problem generated during the operation of the air conditioner outdoor unit, and improving the user's comfort experience.

[0046] In the specific implementation process, the second air outlet 320 is arranged around the first air outlet 310. In this way, an air outlet channel is formed between the second air outlet 320 and the first air outlet 310, and the air outlet channel is arranged opposite to the guide portion 110. The airflow in the guide portion 110 flows into the first air outlet 310 and the second air outlet 320 respectively through the air outlet channel. Compared with the structure in which the air outlet grille 300 can only provide a single airflow direction, the air outlet grille 300 in this embodiment can make the airflow flow out at different angles. After rectifying the airflow, the outflow range of the airflow is expanded, and the efficiency of the air conditioner outdoor unit is improved.

[0047] In this application, if Figure 8As shown, the housing 100 includes an exterior end surface 120, an air outlet grille 300 is disposed on the exterior end surface 120, and a second air outlet portion 320 protrudes relative to the exterior end surface 120. The first air outlet portion 310 is connected to an end of the second air outlet portion 320 away from the exterior end surface 120, so that an air outlet channel formed between the first air outlet portion 310 and the second air outlet portion 320 provides an outflow space for airflow.

[0048] Specifically, a mounting groove 121 is provided on the appearance end surface 120, and the air outlet grille 300 is provided in the mounting groove 121; the mounting groove 121 includes a groove bottom surface 1210 and a groove side wall surface 1211, and the groove side wall surface 1211 is provided around the groove bottom surface 1210, and at least part of the second air outlet 320 is opposite to the groove side wall surface 1211. An opening is provided on the groove bottom surface 1210, and the guide space of the guide portion 110 is connected to the air outlet channel through the opening, and the first air outlet 310 is opposite to the opening. In this way, after the airflow is blown out by the second air outlet 320, the airflow is blown out more smoothly at the second air outlet 320, avoiding the influence of the external airflow on the air pressure at the second air outlet 320, and at the same time, it can also play a dustproof effect.

[0049] In the specific implementation process, the fan assembly 200 includes a guide vane 210, and the height direction of the guide vane 210 is L, with the axial direction of the fan assembly 200 as the height direction; the depth of the installation groove 121 is H1, 0.1L Figure 2 As shown in the figure, by limiting the proportional relationship between L and H1, the air volume and the thickness of the air conditioner outdoor unit can be better integrated. Because when H2 is constant, the smaller H1 is, the larger the protrusion of the grille relative to the panel (H2-H1), the larger the fan air volume, but the greater the impact on the appearance and the thickness of the air conditioner outdoor unit. The larger H1 is, the smaller the protrusion of the grille relative to the panel, the smaller the fan air volume, and the smaller the thickness of the air conditioner outdoor unit.

[0050] The guide part 110 is an annular structure, which encloses a guide space. The axial direction of the guide part 110 is the height direction, the height of the guide part 110 is H3, and the inner diameter of the guide part 110 is D0; 0.05<H3 / D0<0.5. This range is related to manufacturing feasibility and fan performance. The larger D0 is, the larger H3 can be. When H3 is outside this range, that is, D0 is smaller and H3 is larger, it is more difficult to manufacture sheet metal parts. In addition, the distance that the fan blade can extend into the guide ring is (H1+H3). This range of H3 can better match the fan blade to achieve the highest efficiency.

[0051] In the embodiments provided in this application, Figures 8 to 15 ​As shown, the first air outlet portion 310 includes: a first air outlet body 311, the first air outlet body 311 includes a plurality of first air guides 312, each of which is arranged at intervals along the radial direction of the first air outlet body 311, and a first air outlet gap 313 is arranged between two adjacent first air guides 312. Preferably, the first air guides 312 are ribs, and each of the first air guides 312 is respectively annular, so as to rectify the airflow and make it flow out. In a specific implementation, reinforcing ribs are also arranged along the radial direction of the first air outlet body 311, and the reinforcing ribs are respectively connected to each of the first air guides 312 to strengthen the structural strength of the first air outlet body 311. Preferably, there are four reinforcing ribs, which are evenly spaced along the circumferential direction of the first air outlet body 311 to reduce the blocking effect on the airflow.

[0052] Further, the second air outlet portion 320 includes: a second air outlet body 321, the two ends of the second air outlet body 321 are respectively connected to the first air outlet body 311 and the housing 100, and the second air outlet body 321 is arranged around the first air outlet body 311; wherein the second air outlet body 321 includes a plurality of second air guides 322, each of which is arranged at intervals along the circumferential direction of the second air outlet body 321, and a second air outlet gap 323 is arranged between two adjacent second air guides 322. Preferably, the second air guides 322 are ribs, and the airflow is rectified by each second air guide 322 to make the airflow flow out, and cooperate with each first air guide 312 to make the airflow flow out in different directions.

[0053] In the present application, the air outlet grille 300 includes a first air outlet body 311 and a second air outlet body 321, the two ends of the second air outlet body 321 are connected to the first air outlet body 311 and the housing 100 respectively, and the second air outlet body 321 is arranged around the first air outlet body 311; the air conditioner outdoor unit also includes: a mounting body 400, which is arranged on the first air outlet body 311, and the mounting body 400 extends from the first air outlet body 311 toward the middle of the housing 100, and at least part of the fan assembly 200 is arranged on the mounting body 400. The first air outlet body 311 is provided with an avoidance opening, and when the fan assembly 200 is installed on the mounting body 400, the fan assembly 200 is avoided. Preferably, the mounting body 400, the first air outlet body 311 and the guide part 110 are all coaxially arranged, so that when the fan assembly 200 is installed, it is conducive to the coaxial cooperation between it and the guide part 110.

[0054] In order to facilitate the control of the fan assembly 200, the first air outlet 310 and the air guide 110 are respectively provided with a wire groove 130. The fan assembly 200 includes: a driving component 220, which is arranged on the installation body 400, and the connecting wire of the driving component 220 is embedded in the wire groove 130. The installation body 400 is a sleeve structure, and the driving component 220 of the fan assembly 200 is arranged in the sleeve structure.

[0055] In a specific implementation, the fan assembly 200 includes a guide blade 210. Along the outflow direction of the airflow, the guide blade 210 includes a first blade end 211 and a second blade end 212 that are relatively arranged, and the horizontal distance between the first blade end 211 and the second blade end 212 is L; the guide portion 110 includes a first guide end 111 and a second guide end 112 that are relatively arranged, the first guide end 111 is connected to the casing 100, and the second guide end 112 extends toward the middle of the casing 100, and the horizontal distance between the second blade end 212 and the second guide end 112 is S; 0.2<S / L<1.5. The positional relationship between the fan blades and the guide part is that as S increases, the efficiency first increases and then decreases. By limiting the ratio range of S / L, the guide fan blades 210 are extended into a predetermined range within the guide part 110, thereby improving the rectification effect on the airflow, ensuring that the air-conditioning system can still maintain efficient operation under high load, reducing the energy consumption of the cooling equipment, and improving the working efficiency of the fan assembly 200.

[0056] In the present application, since the distance between the opening of the outer cover grille and the front panel of the external unit is H1, the distance that the fan blades can extend into the guide ring is (H1+H3). For most axial flow fan blades, the distance that can be extended is larger, and the position of the fan and the guide ring can have a wider adjustment range, which is more likely to achieve the highest efficiency working state.

[0057] The fan assembly 200 includes a guide vane 210. Along the outflow direction of the airflow, the guide vane 210 includes a first blade end 211 and a second blade end 212 that are arranged opposite to each other. The horizontal distance between the second blade end 212 and the air outlet grille 300 is d, and d>5mm. This arrangement avoids the situation where the distance between the guide vane 210 and the air outlet grille 300 is too small, resulting in interference between the guide vane 210 and the air outlet grille 300.

[0058] Furthermore, the guide vane 210 rotates around a predetermined circular trajectory, and the diameter of the circumferential surface where the predetermined circular trajectory is located is D4; the guide portion 110 is a ring-shaped structure, and the inner diameter of the ring-shaped structure is D0, and D0>D4. This arrangement enables the guide vane 210 to rotate inside the guide portion 110. It can ensure the smooth flow of air in the air conditioning system, prevent friction between the vane and the guide portion, and reduce unnecessary energy loss.

[0059] The air guide portion 110 is an annular structure, and the inner diameter of the annular structure is D0; the air outlet grille 300 includes an air outlet channel 324, and the air outlet channel 324 is arranged between the first air outlet portion 310 and the second air outlet portion 320, and the inner diameter of the second air outlet channel 324 is D2, and D2<D0. d1 is the width of the second air guide 322 (about 5 to 15 mm), that is, (D3-D2) / 2. D3 is the outer diameter of the second air outlet body 321, and D2 is the inner diameter of the second air outlet body 321, that is, the second air outlet body 321 is an annular structure, and the channel surrounded by the inner wall surface of the second air outlet body 321 is a partial channel section of the air outlet channel 324.

[0060] The casing 100 also includes an outer cover 140, a first side plate 161, a second side plate 162, a partition plate 170, a chassis 180 and an upper cover 190. The air outlet grille 300 is arranged on the outer cover 140. The outer cover 140, the first side plate 161, the second side plate 162, the upper cover 190 and the chassis 180 are respectively connected to enclose an installation cavity. The fan assembly 200 and the guide portion 110 are respectively arranged in the installation cavity. A partition plate 170 is also arranged in the installation cavity to divide the installation cavity into a heat exchange cavity and a compressor cavity.

[0061] The recessed portion of the outer cover panel (i.e., the installation groove 121) and the grille portion (i.e., the air outlet grille 300) are the outlets of the outdoor fan airflow. The first air outlet body 311 of the grille portion of the outer cover constitutes the outlet of the outer cover fan air outlet along the direction of the fan blade rotation axis, and the second air outlet body 321 of the grille portion constitutes the lateral outlet of the grille portion. The panel recessed portion makes the lateral air outlet of the grille smoother, and the air outlet area is (2πD2×H2+π(D0)2 / 4), which increases the lateral air outlet area, reduces the resistance of the outdoor fan, and increases the air volume; at the same time, under the condition of the same air volume, the air outlet area increases, thereby reducing the average flow velocity. The vortex is related to the flow velocity. When the flow velocity decreases, the vortex decreases or the intensity decreases, and the noise is reduced, making the user experience more comfortable.

[0062] The distance between the cover and the front panel of the outdoor unit along the direction of the fan blade rotation axis is (H2-H1). When the air outlet area is increased and the resistance is reduced, the thickness of the outdoor unit will not be increased. The structure is more compact, the cabinet volume is large, and the transportation cost is reduced. The experimental test results of this solution are shown in the following table and figure. Under the same power conditions, the air volume of this solution is higher; under the same speed conditions, the air volume is significantly improved. At 900rpm, the air volume is increased by about 5.2%. This shows that this solution has a good effect of improving the fan efficiency of the outdoor unit.

[0063]

[0064]

[0065] The outer cover of the air conditioner outdoor unit has the function of rectifying the airflow from the fan and protecting the outdoor unit. The outer cover is composed of a grille with many small holes. The airflow passes through the outer cover and flows along the grille. The outer cover has a rectifying effect on the airflow discharge; at the same time, human hands or other debris cannot enter the interior of the air conditioner outdoor unit through the small holes of the outer cover grille and contact the rotating fan blades and the live motor. The outer cover can protect the inside of the shell.

[0066] The fan assembly of the air conditioner outdoor unit has many components and poor assembly positioning accuracy, which affects the fan efficiency. The axial coaxiality of the fan blade extending into the guide ring is poor, resulting in uneven gap between the fan blade and the cylindrical surface of the guide ring when the fan blade rotates, that is, the blade tip gap. The size and uniformity of the fan blade tip gap will affect the efficiency and noise level of the fan.

[0067] The grille structure of the outer cover will hinder the air flow, affect the air volume of the outdoor unit, and thus affect the heat exchange efficiency of the heat exchanger, resulting in reduced air conditioning capacity and energy efficiency. When the air flows through the grid, it rubs against the surface of the structure, disturbing the air flow and generating eddies, which will increase the noise of the air conditioner outdoor unit and affect the user's comfort experience.

[0068] Compared with the prior art, the air conditioner outdoor unit of the present application can improve the fan efficiency, make the air conditioner more energy-saving, and improve the air conditioner energy efficiency. At the same time, it reduces the number of parts, reduces costs, reduces the noise of the air conditioner outdoor unit, and optimizes the user comfort.

[0069] The present application also provides an air conditioner, including an air conditioner outdoor unit, and the air conditioner outdoor unit is the air conditioner outdoor unit described above.
